1 2000-07-25 Marius Vollmer <mvo@zagadka.ping.de>
2
3 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
4 scm_assoc_remove_x): Remove only the first cell with a matching
5 key, not all.
6
7 2000-07-24 Marius Vollmer <mvo@zagadka.ping.de>
8
9 * stime.c (scm_strftime): Recognize a return value of zero from
10 strftime as buffer overflow and take care to detect a valid zero
11 length result regardless. Thanks to David Barts!
12
13 2000-07-23 Marius Vollmer <mvo@zagadka.ping.de>
14
15 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
16 scm_assoc_remove_x): Remove all cells whose key is eq, eqv, or
17 equal (respectively) to the argument key, not all cells that are
18 eq, eqv, or equal to the first cell with the argument key. Thanks
19 to Neil Jerram!
20
21 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
22
23 * gc.h (SCM_FREE_CELL_CDR, SCM_SET_FREE_CELL_CDR), hooks.c
24 (make_hook), modules.c (OBARRAY, USES, BINDER): Pack and unpack
25 SCM values appropriately.
26
27 * modules.c (scm_standard_eval_closure): Don't pass an inum to
28 scm_makcclo, but rather a long value.
29
30 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
31
32 read.c (scm_lreadrecparen), srcprop.c (scm_set_source_property_x):
33 SCM_SETCDR and SCM_WHASHSET macros don't deliver a return value.
34 Thanks to Han-Wen Nienhuys for the bug report.
35
36 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
37
38 * root.[ch] (scm_call_catching_errors): Deprecated.
39
40 * root.c (scm_init_root): Initialize the root smob type using the
41 standard initialization functions.
42
43 2000-07-17 Marius Vollmer <mvo@zagadka.ping.de>
44
45 * eval.c (unmemocopy): Don't rely on V being a list of at least
46 one element. Thanks to Bill Schottstaedt!
47
48 2000-07-15 Michael Livshin <mlivshin@bigfoot.com>
49
50 * gc.c (scm_done_free): new.
51 expanded comments about scm_done_malloc.
52
53 * gc.h: added prototype for scm_done_free
54
55 2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
56
57 * gc.h (scm_take_stdin): Removed.
58
59 * gc.h (SCM_VALIDATE_CELL): Delegate cell checks to function
60 scm_assert_cell_valid to allow extensions to the checking
61 functionality without need to recompile everything.
62
63 * gc.[ch] (scm_assert_cell_valid, scm_set_debug_cell_accesses_x):
64 Added as conditionally compiled functions for the case that
65 SCM_DEBUG_CELL_ACCESSES is enabled.
66
67 * gc.c (debug_cells_p): Added to indicate whether compile-time
68 included cell access debugging is run-time enabled.
69
70 * gc.[ch] (scm_gc_running_p): Added to indicate that scm_igc is
71 being executed. Intended to be used instead of scm_gc_heap_lock
72 at most places.
73
74 * error.c (scm_error), gdbint.c (SCM_GC_P): Use scm_gc_running_p
75 instead of scm_gc_heap_lock.
76
77 * gc.c (scm_igc): Set scm_gc_running_p to true while running.
78
79 * gc.c (scm_mark_locations): Don't mark free cells.
80
81 * weaks.c (scm_scan_weak_vectors): Use SCM_FREE_CELL_P instead of
82 SCM_FREEP.
83
84 2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
85
86 * gc.c (scm_mark_locations): Minimized some variable scopes and
87 simplified the code a bit.
88
89 2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
90
91 * gc.h (SCM_SET_FREE_CELL_TYPE, SCM_SET_FREE_CELL_CDR,
92 SCM_FREE_CELL_P, SCM_FREE_CELL_CDR): Added since free cells
93 should not be accessed via SCM_C[AD]R. Further, using dedicated
94 macros to access free cells allows all other cell accessing macros
95 to treat acesses to free cells as errors, thus enabling better
96 error checks for cell accesses. SCM_FREE_CELL_P is supposed to
97 replace SCM_FREEP some time.
98
99 * gc.h (SCM_NEWCELL, SCM_NEWCELL2), gc.c (map_free_list,
100 free_list_length, scm_check_freelist, scm_debug_newcell,
101 scm_debug_newcell2, freelist_length, scm_gc_for_newcell,
102 scm_gc_mark, scm_gc_sweep, init_heap_seg): Only use the dedicated
103 cell accessors when accessing free cells.
104
105 2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
106
107 * gc.h (SCM_CELL_WORD, SCM_CELL_OBJECT): Treat the referenced
108 object as const in order to make the compiler warn about code like
109 SCM_CELL_WORD (x, n) = y. Instead, SCM_SET_CELL_WORD (x, n, y)
110 should be used.
111
112 (SCM_CELL_WORD_LOC, SCM_CARLOC, SCM_CDRLOC): Return the address
113 as an address to a non-const object, since these macros are used
114 to allow direct write access to objects.
115
116 2000-07-07 Dirk Herrmann <D.Herrmann@tu-bs.de>
117
118 * hashtab.c (scm_hash_fn_create_handle_x): Signal an error if the
119 given hash table has no slots.
120
121 2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
122
123 * gc.c (policy_on_error): Added in order to allow alloc_some_heap
124 to react to malloc failures in a context dependent way.
125
126 (scm_check_freelist): No need to flush streams before abort().
127
128 (scm_gc_for_newcell): Try to allocate new memory in three phases:
129 grow heap if preferred, if still no memory available collect
130 garbage, if still no memory available grow heap.
131
132 (heap_segment_table_size): Added to always reflect the actual
133 size of the heap segment table, because scm_n_heap_segs may differ
134 from the heap segment table size.
135
136 (alloc_some_heap): In case of malloc failure, react according to
137 the new policy_on_error parameter (either return to caller or
138 abort immediately). Further, keep heap_segment_table_size up to
139 date.
140
141 (scm_init_storage): Initialize heap_segment_table_size.
142
143 2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
144
145 * gh.h: Don't include <stdio.h>. Thanks to Han-Wen Nienhuys for
146 the hint.
147
148 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
149
150 * __scm.h (SCM_OUTOFRANGE, SCM_NALLOC, SCM_HUP_SIGNAL,
151 SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL, SCM_SEGV_SIGNAL,
152 SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL, SCM_SIG_ORD,
153 SCM_ORD_SIG, SCM_NUM_SIGS): Re-introduce these as deprecated
154 symbols.
155
156 * error.c (scm_wta): Re-introduce dispatching for SCM_OUTOFRANGE
157 and SCM_NALLOC, but as a deprecated feature.
158
159 2000-06-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
160
161 * debug.c: Added #include fluids.h.
162
163 * numbers.c (scm_gr_p, scm_leq_p, scm_geq_p): Turned into
164 primitive generics. (Thanks to Nicolas Neuss.)
165
166 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
167
168 * gc.c (alloc_some_heap): Use scm_memory_error to indicate a
169 failed attempt to get additional memory from the system.
170
171 (scm_gc_for_newcell): Changed the control structure to make the
172 behaviour explicit for the case that gc is not able to free any
173 cells.
174
175 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
176
177 * __scm.h (SCM_OUTOFRANGE): Removed.
178
179 * error.c (scm_wta): Removed sick dispatch code for range
180 errors. (More sick dispatches still to be removed.)
181
182 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
183 scm_hash_fn_remove_x): Eliminate redundant test for if unsigned
184 value is non-negative. Use scm_out_of_range to signal range
185 errors.
186
187 * hooks.c (make_hook), unif.c (scm_aind): Use scm_out_of_range to
188 signal range errors.
189
190 * list.c (scm_list_ref, scm_list_set_x, scm_list_cdr_set_x): Fix
191 error reporting (now uses original input parameter to report wrong
192 type argument errors). Use SCM_OUT_OF_RANGE to report range
193 errors and SCM_WRONG_TYPE_ARG to report type errors.
194
195 * strings.c (scm_substring): Make range checks for negative
196 values explicit (former behaviour relied on an implicit
197 conversion from signed to unsigned). Don't use SCM_ASSERT for
198 range checks.
199
200 * unif.c (scm_aind, scm_transpose_array, scm_bit_set_star_x,
201 scm_bit_count_star): Use scm_out_of_range to signal range
202 errors.
203
204 * unif.c (scm_transpose_array, scm_bit_position), vectors.c
205 (scm_vector_ref, scm_vector_set_x, scm_vector_move_left_x,
206 scm_vector_move_right_x): Use SCM_ASSERT_RANGE to check ranges.
207
208 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
209
210 * validate.h (SCM_VALIDATE_INUM_MIN_COPY,
211 SCM_VALIDATE_INUM_MIN_DEF_COPY, SCM_VALIDATE_INUM_RANGE_COPY):
212 Perform all range checks based on the input value. The former way
213 of using the value that is assigned to the target variable fails
214 if the assignment to the target variable itself can change the
215 value because of type conversion.
216
217 (SCM_ASSERT_RANGE): Use scm_out_of_range to signal range errors.
218
219 2000-06-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
220
221 * gc.c (scm_gc_for_newcell): Behave gracefully also if scm_igc
222 doesn't yield any new cells. In theory this could happen if all
223 cells allocated with NEWCELL are either in use or conservatively
224 marked and all cluster spine cells are conservatively marked.
225 (Thanks to Dirk.)
226
227 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
228
229 * __scm.h (SCM_NALLOC): Removed.
230
231 * error.c (scm_wta): Removed sick dispatch code for memory
232 errors. (More sick dispatches still to be removed.)
233
234 * numbers.c (scm_mkbig, scm_adjbig), ports.c (scm_make_port_type),
235 random.c (scm_i_copy_rstate, scm_c_make_rstate), smob.c
236 (scm_make_smob_type), srcprop.c (scm_make_srcprops), vectors.c
237 (scm_vector_set_length_x): Now using scm_memory_error to signal
238 memory errors.
239
240 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
241
242 * __scm.h: Removed some commented code and fixed some comments.
243
244 (SCM_HUP_SIGNAL, SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL,
245 SCM_SEGV_SIGNAL, SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL,
246 SCM_SIG_ORD, SCM_ORD_SIG, SCM_NUM_SIGS): Removed.
247
248 * async.c: Removed some commented code.
249
250 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
251
252 * gc.c (scm_gc_mark, scm_gc_sweep, scm_must_malloc,
253 scm_must_realloc, scm_must_free, alloc_some_heap): Use the
254 appropriate error signalling function.
255
256 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
257
258 * root.h (scm_first_type): Removed.
259
260 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
261
262 * gc.c (MIN_GC_YIELD): Removed.
263
264 2000-06-28 Michael Livshin <mlivshin@bigfoot.com>
265
266 * gc.c (scm_gc_for_newcell): don't try to do GC if it's blocked,
267 allocate instead.
268
269 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
270
271 * async.c (scm_gc_async, scm_gc_vcell, scm_sys_gc_async_thunk):
272 Moved to gc.c.
273
274 (scm_init_async): Moved initialization for scm_gc_async and
275 scm_gc_vcell to gc.c. Moved initialization of scm_asyncs here
276 from gc.c.
277
278 * async.h (scm_gc_async): Not globally visible any more.
279
280 * gc.c (scm_gc_stats): Made callable even from within regions
281 where gc is blocked.
282
283 (scm_gc_end): Eliminate the hardcoding of the marking of the
284 scm_gc_async from the gc core.
285
286 (scm_init_storage): Don't initialize the scm_asyncs list here.
287 This is now done in asyncs.c.
288
289 (scm_gc_vcell): Moved here from async.c.
290
291 (gc_async): Renamed from scm_gc_async, moved here from async.c
292 and made static.
293
294 (gc_async_thunk): Renamed from scm_sys_gc_async_thunk and moved
295 here from async.c.
296
297 (mark_gc_async): New hook function for scm_after_gc_c_hook.
298
299 (scm_init_gc): Added initialization of scm_gc_vcell and
300 gc_async. Further, add mark_gc_async to scm_after_gc_c_hook.
301
302 * init.c (scm_boot_guile_1): scm_init_gc requires asyncs to be
303 initialized.
304
305 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
306
307 * gc.c (scm_igc): Removed commented code that once was intended
308 to unprotect struct types with no instances.
309
310 * root.h (scm_type_obj_list): Removed.
311
312 2000-06-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
313
314 * async.c (scm_init_async): Switch to standard way of smob
315 initialization.
316
317 2000-06-21 Michael Livshin <mlivshin@bigfoot.com>
318
319 * guile-doc-snarf.in: use cut instead of sed, that's much much
320 faster. also, don't call basename more than needed. and, to gain
321 a couple of microseconds more, don't call cat needlessly. (thanks
322 to Brad Knotwell).
323
324 2000-06-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
325
326 * guile-snarf.awk.in, guile-snarf.in, snarf.h: Rename SCM__I to
327 SCM_SNARF_INIT_START, SCM__D to SCM_SNARF_DOC_START, SCM__S to
328 SCM_SNARF_DOCSTRING_START and SCM__E to SCM_SNARF_DOCSTRING_END.
329
330 2000-06-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
331
332 * eval.c, eval.h (scm_top_level_lookup_closure_var): Added.
333 #include "libguile/fluids.h".
334
335 * eval.h (SCM_TOP_LEVEL_LOOKUP_CLOSURE): New macro which replaces
336 SCM_CDR (scm_top_level_lookup_closure_var) everywhere.
337
338 * root.h (scm_top_level_lookup_closure_var,
339 scm_system_transformer): Removed. (It's no sense in having the
340 *variable* be a "fluid".)
341
342 * root.c (mark_root): Removed marking of
343 s->top_level_lookup_closure_var and s->system_transformer.
344
345 * modules.c (scm_selected_module): the_module is now a fluid.
346
347 2000-06-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
348
349 * gc.h, tags.h: Be kind to compilers which must see hash signs in
350 column 0. (Thanks to Ian Grant.)
351
352 * numbers.h: Put #ifdef HAVE_LONG_LONGS around declarations using
353 the long_long type. (Thanks to Bernard Urban.)
354
355 2000-06-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
356
357 * gc.c, gc.h (scm_default_init_heap_size_1,
358 scm_default_min_yield_1, scm_default_init_heap_size_2,
359 scm_default_min_yield_2, scm_default_max_segment_size): New global
360 variables. Can be customized by the application before booting
361 Guile. (We might want to be able to control these parameters
362 dynamically through the "options interface" in the future, but
363 note that that is additional functionality. Here we're giving
364 default values which the environment variables can override.)
365
366 * list.c (scm_cons_star): Updated comment.
367
368 * smob.h: Changed comments for scm_make_smob_type and
369 scm_make_smob_type_mfpe, warning that the latter might be
370 deprecated in a future release.
371
372 2000-06-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
373
374 * list.[ch] (scm_cons_star/cons*): Renamed from
375 scm_list_star/list*.
376
377 * list.[ch] (scm_list_star/list*): Provided as a deprecated alias
378 for scm_cons_star/cons*.
379
380 * gc.c (scm_protect_object): Updated comment.
381
382 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX): Removed.
383
384 * tags.h (SCM_UNPACK_CAR, SCM_NDOUBLE_CELLP): Removed.
385
386 2000-06-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
387
388 * init.c, init.h (scm_initialized_p): Renamed from `initialized'
389 and made global.
390
391 * gdbint.c (gdb_print): Print warning instead of calling scm_write
392 if Guile isn't yet initialized.
393
394 * print.c (scm_current_pstate, scm_make_print_state): Simplified
395 tests, using the assumption that Guile has been initialized.
396
397 Sun Jun 18 14:45:21 2000 Greg J. Badros <gjb@cs.washington.edu>
398
399 * print.c (s_scm_current_pstate): Do not segfault when the
400 print_state_pool is unitialized in `current-pstate', and better
401 verify its state before altering it in scm_make_print_state().
402
403 2000-06-18 Michael Livshin <mlivshin@bigfoot.com>
404
405 * scmsigs.c (s_scm_sigaction): guard the SIGIOT case with an
406 #ifdef -- it's missing on at least one platform. (thanks to
407 Jan Nieuwenhuizen).
408
409 2000-06-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
410
411 * list.c (list*): Added documentation from common-list.scm.
412
413 2000-06-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
414
415 * gc.c (scm_unprotect_object): The reference count is guaranteed
416 to be a positive number.
417
418 2000-06-15 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
419
420 * eval.c: Updated comment above scm_map.
421
422 2000-06-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
423
424 * gc.c (scm_protect_object): Avoid looking up the object handle
425 twice.
426 (scm_unprotect_object): Abort if scm_unprotect_object is called on
427 an unprotected object.
428
429 2000-06-14 Michael Livshin <mlivshin@bigfoot.com>
430
431 * gc.c (scm_unprotect_object): fix a nasty typo bug (thanks to
432 Dirk Herrmann).
433
434 2000-06-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
435
436 * socket.c (scm_getsockopt): Changed type for `optlen' from int to
437 size_t.
438 (scm_accept, scm_getsockname, scm_getpeername, scm_recvfrom):
439 Ditto for `tmp_size'.
440 (scm_addr_buffer_size): Changed type from int to size_t.
441
442 * random.c: #include <string.h>. (Needed by memcpy.)
443
444 * guile-snarf.awk.in: Replace the dot_doc_file arg with "-",
445 indicating stdin, instead of "" and don't reset ARGC. This is a
446 workaround for `nawk' in AIX 4.3 on RS6000 but, as far as I know,
447 it is correct, and perhaps even better.
448
449 2000-06-14 Gary Houston <ghouston@arglist.com>
450
451 * scmsigs.c (scm_init_scmsigs): if HAVE_SIGINTERRUPT is not
452 defined, add SA_RESTART to the sigaction flags correctly
453 (thanks to Dale P. Smith).
454
455 2000-06-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
456
457 * strings.c: #include <string.h>. (Thanks to Bill Schottstaedt.)
458
459 * net_db.c (scm_resolv_error): Only use macro NETDB_INTERNAL if
460 defined. It isn't on sgi irix 5.3. (Thanks to Bill Schottstaedt.)
461
462 * Makefile.am (.c.doc): Pipe output (the .x contents) to /dev/null.
463
464 2000-06-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
465
466 * fports.c (scm_setvbuf): Use `free' instead of `scm_must_free'
467 since read and write buffers are allocated by `malloc'.
468
469 * Makefile.am: Removed old test code.
470
471 * gh_test_c.c, gh_test_repl.c: Removed.
472
473 2000-06-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
474
475 * iselect.c (SCM_NLONGBITS): Add workaround for the Sun 4.2
476 compiler.
477
478 * inet_aton.c (inet_aton): Cast init value for `cp'.
479
480 * ramap.c (s_scm_array_fill_x): Cast `ve' properly in case
481 `scm_tc7_uvect'.
482
483 * symbols.c (scm_intern_obarray_soft,
484 scm_sysintern0_no_module_lookup): Cast `name' to unsigned char ptr
485 in calls to scm_strhash.
486
487 * strports.c (st_resize_port): Substituted SCM_UCHARS for
488 SCM_CHARS.
489 (st_write): Cast argument to strncpy to char ptr.
490 (scm_mkstrport): Substituted SCM_ROUCHARS for SCM_ROCHARS.
491 (scm_strport_to_string): Cast argument to scm_makfromstr to char
492 ptr.
493
494 * ports.c (scm_ungetc): Cast value to unsigned char ptr before
495 storing in putback_buf.
496 (scm_unread_string): Substituted SCM_ROCHARS for SCM_ROUCHARS.
497
498 * ioext.c (s_scm_read_line): Cast result of call to
499 scm_do_read_line to unsigned char ptr.
500
501 * gdbint.c (SEND_STRING): Cast argument to char pointer.
502
503 * fports.c (fport_flush): Declare `ptr' as unsigned char (was
504 char).
505
506 * Makefile.am (DOT_DOC_FILES): List doc-files explicitly. (We
507 shouldn't use Make rules which aren't supported by most Make
508 programs.)
509 (OMIT_DEPENDENCIES): Defined to "libguile.h ltdl.h". (We don't
510 want these dependencies recorded, since they would get bogus
511 relative paths; libguile.h is only used in gh.h and guile.c.)
512 (EXTRA_DOT_X_FILES, EXTRA_DOT_DOC_FILES): New variables.
513 (guile-procedures.txt): Depend on EXTRA_DOT_DOC_FILES.
514 (modinclude_HEADERS): Removed kw.h.
515
516 * guile-snarf.in: Change regexp "^SCM__I" --> "^ *SCM__I".
517 (The preprocessor might insert spaces before the identifier.)
518
519 * snarf.h (SCM_SNARF_HERE, SCM_SNARF_INIT, SCM_SNARF_DOCS):
520 Renamed from SCM_HERE, SCM_INIT, SCM_DOCS.
521
522 * smob.h (scm_smobfuns): Removed deprecated type.
523
524 * smob.c, smob.h (scm_newsmob): Removed deprecated function.
525 (Replaced by `scm_make_smob_type'.)
526
527 * keywords.c (scm_tc16_kw): Removed deprecated type.
528 (Replaced by scm_tc16_keyword.)
529
530 * kw.h: Removed deprecated header file.
531
532 * evalext.c (serial-map): Removed deprected alias for scm_map.
533 (Has been replaced by `map-in-order'.)
534
535 * ramap.c (serial-array-copy!, serial-array-map!): Removed
536 depracted aliases. (Replaced by `array-copy-in-order!' and
537 `array-map-in-order'.)
538
539 2000-06-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
540
541 * gc.h (SCM_VALIDATE_CELL): Rewritten.
542 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
543 SCM_SET_CELL_OBJECT): Use new version of SCM_VALIDATE_CELL.
544 (Thanks to Han-Wen Nienhuys.)
545
546 2000-06-10 Michael Livshin <mlivshin@bigfoot.com>
547
548 * guile-doc-snarf.in: don't pipe the CPP output right into sed --
549 write it to the temp file first and check the CPP return code.
550 (I introduced this bug earlier, and this probably caused people
551 with non-GNU C preprocessors to get empty *.x files and not to
552 have the build fail right away...).
553
554 * scmsigs.c (s_scm_sigaction): guard the SIGSYS case with an ifdef
555 -- at least my libc5-based Linux system doesn't define SIGSYS.
556
557 2000-06-08 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
558
559 * snarf.h, guile-snarf.awk.in, guile-snarf.in: Replaced snarf
560 markers with identifiers (SCM__I, SCM__D, SCM__S, SCM__E).
561 (Thanks to Bernard Urban.)
562
563 2000-06-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
564
565 * modules.c (scm_system_module_env_p): Fixed detection of system
566 modules.
567
568 2000-06-06 Marius Vollmer <mvo@zagadka.ping.de>
569
570 * scmsigs.c (scm_sigaction): Silently ignore setting handlers for
571 `program error signals' because they can't currently be handled by
572 Scheme code.
573
574 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
575
576 * procs.h (SCM_SET_SUBRF): Added.
577
578 * procs.c (scm_make_subr_opt): Don't assign to SCM_SUBRF, use
579 SCM_SET_SUBRF instead. Thanks to Bernard Urban for the bug
580 report.
581
582 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
583
584 * gc.h (SCM_CARLOC, SCM_CDRLOC): Don't take the address of a SCM
585 value.
586
587 * sort.c (scm_sorted_p, scm_merge, scm_merge_list_x,
588 scm_merge_list_step): Don't take the address of SCM_CAR. Use
589 SCM_CARLOC instead. Thanks to Bernard Urban for the bug report.
590
591 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
592
593 * boolean.h (SCM_TRUE_P): Removed, as people might use it as a
594 replacement for !SCM_FALSEP.
595
596 * backtrace.c (display_error_body), boolean.h (SCM_BOOLP), gc.c
597 (scm_unhash_name), gh_data.c (gh_module_lookup), load.c
598 (scm_primitive_load), print.c (scm_simple_format), procs.c
599 (scm_procedure_documentation), procs.h (SCM_TOP_LEVEL), ramap.c
600 (scm_array_fill_int), scmsigs.c (scm_sigaction), stacks.c
601 (narrow_stack, scm_make_stack, scm_stack_id), symbols.c
602 (scm_string_to_obarray_symbol), throw.c (scm_catch,
603 scm_lazy_catch, scm_ithrow), unif.c (scm_make_uve, scm_array_p,
604 scm_array_set_x, scm_bit_set_star_x, scm_bit_count_star),
605 validate.h (SCM_VALIDATE_BOOL_COPY, SCM_VALIDATE_PROC): Replace
606 uses of SCM_TRUE_P (x) with SCM_EQ_P (x, SCM_BOOL_T).
607
608 2000-06-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
609
610 * eval.c (scm_badformalsp): New static function.
611 (SCM_CEVAL): Check arguments for procedure-with-setter closures.
612 (Thanks to Keisuke Nishida.)
613
614 The major reason for Guile's slow loading speed has been the fact
615 that a chain of Scheme level procedures has been evaluated for
616 every top-level symbol lookup during the first pass through the
617 code.
618
619 The following is a kludge which I suggested four years ago, and
620 which I've repeatedly suggested since. Personally, I've never
621 been bothered by Guile's slow loading speed, so I thought I would
622 let someone else do it...
623
624 But since the new environments will be included first in
625 Guile-1.5, I thought it would make people happy to get the kludge
626 into 1.4.
627
628 * modules.c: Added #include "libguile/vectors.h";
629 Added #include "libguile/hashtab.h";
630 Added #include "libguile/struct.h";
631 Added #include "libguile/variable.h";
632 Capture Scheme level `module-make-local-var!' to be used in the
633 standard eval closure.
634 (scm_standard_eval_closure): New primitive.
635
636 * modules.h (scm_standard_eval_closure): Declare.
637
638 * eval.c (scm_lookupcar): Test for !SCM_CONSP (SCM_CAR (env))
639 instead of SCM_TRUE (scm_procedurep (SCM_CAR (env))).
640
641 * symbols.c (scm_sym2vcell): Bypass dispatch in the evaluator for
642 standard eval closures.
643
644 * variable.c: Code layout fixes.
645
646 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
647
648 * Makefile.am: Added LIBS line to libpath which accidentally
649 disappeared in the change of 2000-06-01.
650 (Thanks to Dale P. Smith.)
651
652 2000-06-03 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
653
654 * scmsigs.c (scm_segfault): Removed. (Was probably added by
655 mistake since it is not mentioned in ChangeLog.)
656
657 * gc.h (SCM_VALIDATE_CELL): Cast result to (void) in order to
658 avoid compiler warnings in gcc. (Does this work for other
659 compilers?)
660
661 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
662
663 * gc.h (SCM_VALIDATE_CELL): Don't "use" the value returned by
664 abort ().
665 (SCM_CARLOC, SCM_CDRLOC): Define directly instead of using
666 SCM_CELL_OBJECT_0 and SCM_CELL_OBJECT_1. It's not correct to take
667 the address of these expressions since they use SCM_VALIDATE_CELL.
668 (Thanks to Bernard Urban.)
669
670 * dynl.c: Changed #include <ltdl.h> --> #include
671 "libltdl/ltdl.h". (Thanks to Bill Schottstaedt.)
672
673 2000-06-01 Craig Brozefsky <craig@red-bean.com>
674
675 * Makefile.am: libguile_la_LDFLAGS gets -version-info args
676 from GUILE-VERSION definition of LIBGUILE version. Added to
677 libpath.h definitions for guileversion and libguileversion which
678 both get their values from GUILE-VERSION definition.
679
680 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
681
682 * numbers.h (SCM_BIGP): Don't use SCM_SMOB_PREDICATE in header
683 file: Code using numbers should not be required to include
684 smob.h.
685
686 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
687
688 * coop-threads.c.cygnus, coop-threads.h.cygnus, fsu-pthreads.h,
689 mit-pthreads.c, mit-pthreads.h: Deleted.
690
691 * Makefile.am (EXTRA_DIST), scmsigs.c, threads.[ch]: Drop
692 references to deleted files and fsu/mit thread support in
693 general.
694
695 2000-05-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
696
697 * hooks.c (symbol_name, scm_create_hook): Restored the original
698 behaviour of scm_create_hook. Changing it was bad as Carl
699 R. Witty has pointed out.
700
701 * gc.c (scm_init_gc): We can still rely on scm_create_hook to
702 protect the object.
703
704 2000-05-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
705
706 * gc.c (scm_init_gc): Protect scm_after_gc_hook, since this will
707 soon not be done by scm_create_hook any longer.
708
709 * hooks.c (make_hook, print_hook, scm_create_hook,
710 scm_make_hook_with_name, scm_make_hook), hooks.h (SCM_HOOK_NAME,
711 SCM_HOOK_PROCEDURES, SCM_SET_HOOK_PROCEDURES,
712 scm_make_hook_with_name), init.c (scm_boot_guile_1): Hooks no
713 longer have names. As an intermediate solution, the name
714 predicate is emulated via object properties, but use of this
715 feature is deprecated.
716
717 * hooks.h (scm_free_hook): Removed, as it is never defined.
718
719 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
720
721 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_FIXABLE):
722 Un-deprecated since otherwise user code can't determine whether a
723 number fits into an inum any longer. The names should be changed
724 some time, though.
725
726 * numbers.c (scm_big2inum): Eliminated use of SCM_UNEGFIXABLE.
727
728 * tags.h (SCM_UNPACK_CAR): Deprecated.
729
730 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
731
732 * filesys.h (SCM_OPDIRP), fluids.h (SCM_FLUIDP, SCM_FLUID_NUM),
733 fports.h (SCM_OPFPORTP, SCM_OPINFPORTP, SCM_OPOUTFPORTP), hooks.h
734 (SCM_HOOK_ARITY), keywords.h (SCM_KEYWORDP, SCM_KEYWORDSYM),
735 numbers.h (SCM_NUMP, SCM_BIGSIGN, SCM_BDIGITS, SCM_NUMDIGS):
736 Replace SCM_UNPACK_CAR appropriately. Don't access cells via
737 SCM_{SET}?C[AD]R unless they are known to be cons cells.
738
739 * gc.c (scm_heap_seg_data_t, scm_mark_locations, scm_cellp,
740 init_heap_seg): Remove unused struct member variable 'valid'.
741
742 2000-05-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
743
744 * fports.c (fport_write), ports.c (scm_markstream, scm_port_mode,
745 scm_print_port_mode), ports.h (SCM_OPPORTP, SCM_OPINPORTP,
746 SCM_OPOUTPORTP, SCM_INPUT_PORT_P, SCM_OUTPUT_PORT_P, SCM_OPENP),
747 procs.h (SCM_CLOSCAR), unif.h (SCM_ARRAY_NDIM, SCM_ARRAY_CONTP),
748 variable.h (SCM_VARIABLEP): Replace SCM_UNPACK_CAR
749 appropriately.
750
751 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
752
753 * gc.c (free_list_length), hash.c (scm_hasher), macros.c
754 (scm_macro_type), objects.c (scm_class_of), options.c
755 (scm_options), print.c (scm_iprin1), strports.c (st_seek), throw.c
756 (SCM_LAZY_CATCH_P): Replace SCM_UNPACK_CAR appropriately.
757
758 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
759
760 * eval.c (scm_macroexp, SCM_CEVAL, scm_force), tags.h: Replace
761 SCM_UNPACK_CAR with SCM_CELL_TYPE or SCM_CELL_WORD_0.
762
763 * eval.c (scm_force): Add documentation.
764
765 * eval.c (scm_force, scm_cons_source): Don't access cells via
766 SCM_{SET}?C[AD]R unless they are known to be cons cells.
767
768 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
769
770 * strings.h (SCM_NSTRINGP, SCM_NRWSTRINGP), tags.h
771 (SCM_NDOUBLE_CELLP), vectors.h (SCM_NVECTORP): Deprecated.
772
773 * gc.c (scm_igc), gc.h (SCM_PTR_MASK, SCM_PTR_LT): Removed #ifdef
774 nosve #endif conditionally compiled code.
775
776 2000-05-23 Michael Livshin <mlivshin@bigfoot.com>
777
778 * gc.c (scm_heap_seg_data_t): fixed comment for the `span' member.
779
780 2000-05-22 Michael Livshin <mlivshin@bigfoot.com>
781
782 * guile-doc-snarf.in: put the preprocessed file through sed to
783 trim all lines to 1024 chars. I hope it doesn't break anybody's
784 sed. we'll see. (note: this is lossy trimming, i.e. the spill
785 isn't wrapped around but actually chopped off. this seemed to me
786 safe because the current snarfer doesn't understand multi-line
787 cookies anyway. in the long term, it would be nice not to depend
788 on AWK for anything.)
789
790 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): reverted
791 the previous change to this macros, after deciding to torture the
792 snarfer instead.
793
794 2000-05-21 Michael Livshin <mlivshin@bigfoot.com>
795
796 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): brought
797 the yucky, ugly and nasty conditional compilation back. sorry,
798 but it was either that or requiring GAWK to build Guile.
799 (lots of places): removed the code that implemented the old GC
800 scheme.
801
802 * init.c (scm_boot_guile_1): removed the code conditioned on
803 !GUILE_NEW_GC_SCHEME.
804
805 * __scm.h: (GUILE_NEW_GC_SCHEME): removed.
806
807 * gc.c (scm_protect_object, scm_unprotect_object): change the
808 implementation to more efficient (at least in the time complexity
809 sense). the calls should now also be thread-safe -- I suspect
810 that people expect them to be. (thanks to Han-Wen Nienhuys)
811 (lots of places): removed the code that implemented the old GC
812 scheme.
813
814 * hashtab.c (scm_hash_fn_create_handle_x): add missing
815 SCM_REALLOW_INTS before return. I really wonder about the
816 possible interactions between hashtables, threads & GC. it
817 doesn't look healthy at all.
818
819 2000-05-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
820
821 * unif.c (scm_bit_count): Fixed the parameter checks. Thanks to
822 Dale P. Smith.
823
824 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
825
826 * __scm.h (SCM_DEBUG_CELL_ACCESSES), gc.h (SCM_): Added as a new
827 debug option to verify all accesses to cells actually access
828 objects on the heap.
829
830 * gc.h (SCM_VALIDATE_CELL): Added. Only performs validation if
831 SCM_DEBUG_CELL_ACCESSES is set to 1.
832
833 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
834 SCM_SET_CELL_OBJECT): Use SCM_VALIDATE_CELL to check every cell
835 that is accessed.
836
837 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
838
839 * gh_data.c (gh_scm2chars, gh_scm2shorts, gh_scm2longs,
840 gh_scm2floats, gh_scm2doubles): Change !SCM_NIMP to SCM_IMP.
841
842 * gc.c (scm_cellp): Fixed and simplified.
843
844 * throw.c (JBJMPBUF, SETJBJMPBUF, SCM_JBDFRAME, SCM_SETJBDFRAME,
845 make_jmpbuf, scm_init_throw): Now using double cells to represent
846 jump buffers when using debug extensions.
847
848 (freejb): Removed.
849
850 2000-05-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
851
852 * gh.h gh_data.c gh_funcs.c (gh_new_procedure*, gh_chars2byvect,
853 gh_shorts2svect, gh_longs2ivect, gh_ulongs2uvect, gh_floats2fvect,
854 gh_doubles2dvect, gh_doubles2scm, gh_define, gh_lookup,
855 gh_module_lookup): Accept const pointers as parameters.
856
857 * gh.h gh_data.c (gh_int2scmb): Deprecated.
858
859 2000-05-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
860
861 * __scm.h (SCM_DEBUG_REST_ARGUMENT): Renamed from
862 SCM_DEBUG_REST_ARGUMENTS in order to clarify that we don't test
863 the actual arguments in the list, but rather the rest argument as
864 a list of arguments.
865
866 * validate.h (SCM_VALIDATE_REST_ARGUMENT): Added.
867
868 * async.c (scm_noop), eval.c (scm_map, scm_for_each), list.c
869 (scm_list_star, scm_append, scm_append_x), ports.c
870 (scm_close_all_ports_except), ramap.c (scm_array_map_x,
871 scm_array_for_each), regex-posix.c (scm_make_regexp), stacks.c
872 (scm_make_stack), strings.c (scm_string_append), struct.c
873 (scm_make_struct, scm_make_vtable_vtable): Validate rest arguments.
874
875 * dynl.c (DYNL_GLOBAL, sysdep_dynl_link, kw_global, sym_global,
876 scm_dynamic_link, scm_init_dynamic_linking), dynl.h
877 (scm_dynamic_link): Removed possibility to pass flags to
878 scm_dynamic_link, as it had no effect anyway.
879
880 * filesys.c (scm_fcntl): Made single optional rest argument into
881 a standard optional argument.
882
883 * hooks.c (scm_run_hook): A list of rest arguments is never
884 SCM_UNBNDP.
885
886 * list.c (scm_append, scm_append_x), stacks.c (scm_make_stack),
887 strings.c (scm_string_append): Don't perform half-hearted checks
888 to see whether the rest argument forms a proper list any more, use
889 SCM_VALIDATE_REST_ARGUMENTS instead.
890
891 * ports.c (scm_close_all_ports_except): Accept empty list of rest
892 arguments.
893
894 * posix.c (scm_convert_exec_args), print.c (scm_simple_format):
895 Simplify verification of rest argument.
896
897 * stacks.c (scm_make_stack), stacks.h (scm_make_stack), throw.c
898 (ss_handler, handler_message): Make first mandatory rest argument
899 of scm_make_stack into a standard mandatory argument.
900
901 * unif.c (scm_transpose_array, scm_enclose_array,
902 scm_array_in_bounds_p), unif.h (scm_transpose_array,
903 scm_enclose_array, scm_array_in_bounds_p): Make first mandatory
904 rest argument into a standard mandatory argument.
905
906 2000-05-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
907
908 * __scm.h: Added SCM_DEBUG as default debug option. (Thanks to
909 Keisuke Nishida for the suggestion.) Added debug option
910 SCM_DEBUG_REST_ARGUMENTS.
911
912 * eval.c (scm_map, scm_for_each): Make sure all lists have the
913 same length. Also, removed redundant parameter checks.
914
915 2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
916
917 * Makefile.am: Let 'make clean' remove *.x and *.doc files.
918
919 * __scm.h: Improved explanation of giving options to make.
920
921 * __scm.h (SCM_DEBUG_TYPING_STRICTNESS), tags.h
922 (SCM_STRICT_TYPING, SCM_DEBUG_TYPING_STRICTNESS): Renamed
923 SCM_STRICT_TYPING to SCM_DEBUG_TYPING_STRICTNESS and moved the
924 corresponding declaration and comment to __scm.h.
925

927 (scm_remainder, scm_modulo), numbers.h (SCM_SRS, SCM_MAKINUM,
928 SCM_INUM): Removed conditionally compiled code for Turbo C.
929
930 * gdbint.c (gdb_maybe_valid_type_p): Eliminated call to scm_tag.
931 That check can be assumed to be redundant except for very rare
932 conditions that actually indicate broken heap data.
933
934 2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
935
936 * numbers.c (scm_logcount, scm_integer_length): Reordered
937 dispatch sequence.
938
939 2000-05-15 Gary Houston <ghouston@arglist.com>
940
941 * stime.c (scm_strftime): don't reset TZ if zone is an empty
942 string. append a "0" to the zone for TZ.
943
944 2000-05-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
945
946 * numbers.c (scm_logbit_p, scm_bit_extract): Reordered dispatch
947 sequence.
948
949 (scm_bit_extract): Fixed handling of bignums.
950

959 'serial-array-map!), smob.c (scm_newsmob), smob.h (scm_smobfuns,
960 scm_newsmob), tag.c (scm_tag), tag.h (scm_tag), tags.h
961 (scm_tc16_flo, scm_tc_flo, scm_tc_dblr, scm_tc_dblc): Wrapped
962 deprecated code between #if (SCM_DEBUG_DEPRECATED == 0) #endif.

965 scm_output_port_p), print.c (scm_get_print_state), validate.h
966 (SCM_VALIDATE_CHAR): Replace use of deprecated macros
967 SCM_INPORTP, SCM_OUTPORTP, SCM_ICHRP by SCM_INPUT_PORT_P,
968 SCM_OUTPUT_PORT_P, SCM_CHARP, respectively.
969
970 2000-05-14 Gary Houston <ghouston@arglist.com>
971
972 * stime.c (scm_strftime): if HAVE_TM_ZONE is not defined, hack the
973 TZ environment variable so that the %Z format returns the zone
974 from the input vector instead of the system default.
975
976 from Keisuke Nishida:
977 * fports.c (scm_setvbuf): minor docstring fix.
978 * ports.h (scm_generic_fgets): obsolete prototype deleted.
979
980 2000-05-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
981
982 * __scm.h: Added new section for debugging options.
983
984 (SCM_DEBUG_DEPRECATED): If 1, no deprecated code is included to
985 help developers to get rid of references to deprecated code.
986
987 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_UNEGFIXABLE,
988 SCM_FIXABLE, SCM_FLOBUFLEN): These macros are no longer provided
989 as part of the interface and are marked as deprecated in the
990 header file.
991
992 * numbers.c (scm_make_real, scm_make_complex): Inlined the
993 corresponding macros SCM_NEWREAL and SCM_NEWCOMPLEX,
994 respectively.
995
996 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX, SCM_INEXP, SCM_CPLXP,
997 SCM_REAL, SCM_IMAG, SCM_REALPART, scm_makdbl, SCM_SINGP,
998 SCM_NO_BIGDIG, SCM_NUM2DBL, scm_dblproc): Deprecated.
999
1000 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1001
1002 * gc.h (scm_cell, SCM_CELL_WORD, SCM_CELL_OBJECT,
1003 SCM_SET_CELL_WORD, SCM_SET_CELL_OBJECT): Scheme cells now consist
1004 of two scm_bits_t values instead of two SCM values, because it is
1005 legal for cell entries to hold values that are not scheme objects.
1006
1007 (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR):
1008 Use SCM_SETC[AD]R to modify contents of pairs.
1009
1010 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1011
1012 * numbers.c (IS_INF, isfinite): Added FIXME comment.
1013
1014 (scm_abs, scm_magnitude): Make these two independent of each
1015 other. scm_abs now reports an error if given a complex argument.
1016
1017 (scm_istr2flo, scm_integer_p). Use SCM_REAL_VALUE instead of
1018 SCM_REALPART if the object is known to be real.
1019
1020 (scm_init_numbers): No need to use SCM_NEWREAL macro for speed
1021 here.
1022
1023 * numbers.h (SCM_SINGP): Set to 0 instead of SCM_BOOL_F.
1024
1025 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1026
1027 * eq.c (scm_eqv_p): Separate handling of real and complex
1028 values. Remove #ifdef SCM_BIGDIG #endif test.
1029
1030 * eval.c (SCM_CEVAL, SCM_APPLY), gh_data.c (gh_scm2floats,
1031 gh_scm2doubles), hash.c (scm_hasher), ramap.c (scm_array_fill_int,
1032 ramap_rp, scm_array_map_x), random.c (vector_scale,
1033 vector_sum_squares), unif.c (scm_make_uve, scm_array_p,
1034 scm_array_set_x): Use SCM_REAL_VALUE instead of SCM_REALPART if
1035 the object is known to be real. Use SCM_COMPLEXP instead of
1036 deprecated SCM_CPLXP. Use SCM_INEXACTP instead of deprecated
1037 SCM_INEXP.
1038
1039 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1040
1041 * numbers.c: No need to include unif.h.
1042
1043 (IS_INF): Returned to old test for now: x == x + 1 will not work
1044 for large numbers due to rounding errors.
1045 Thanks to Kalle Olavi Niemitalo.
1046
1047 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
1048
1049 * numbers.c (scm_divbigdig): Removed outdated comment.
1050
1051 (scm_number_to_string, scm_string_to_number, scm_number_p,
1052 scm_real_p, scm_integer_p, scm_inexact_p, scm_gr_p, scm_leq_p,
1053 scm_geq_p, scm_make_rectangular, scm_make_polar,
1054 scm_inexact_to_exact): Added comments.
1055
1056 (add1, scm_init_numbers): Removed add1.
1057
1058 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
1059
1060 * numbers.c (IS_INF): The new test is x == x + 1. The old test
1061 x == x/2 did not work for zero values. Thanks to Han-Wen Nienhuys
1062 and Ivan Toshkov.
1063
1064 (scm_number_to_string, scm_sum, scm_difference, scm_two_doubles,
1065 scm_num2long, scm_num2long_long, scm_num2ulong): Reordered
1066 dispatch sequence.
1067
1068 2000-05-09 Marius Vollmer <mvo@zagadka.ping.de>
1069
1070 * scmsigs.c (take_signal): Execute SCM_ASYNC_TICK for SIGSEGV,
1071 SIGILL and SIGBUS signals. These signals are not continuable and
1072 must be handled for real right away.
1073
1074 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1075
1076 * numbers.c (scm_zero_p, scm_positive_p, scm_negative_p,
1077 scm_real_part, scm_imag_part, scm_magnitude,
1078 scm_inexact_to_exact): Reordered dispatch sequence.
1079
1080 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1081
1082 * feature.c: No need to include "libguile/smob.h"
1083
1084 (scm_loc_features, features, scm_add_feature, scm_init_feature):
1085 Removed variable 'scm_loc_features' as a pointer to the SCM value
1086 holding the features list. Using variable 'features' instead,
1087 which holds the interned pair. Thus, SCM_SETCDR can be used
1088 instead of pointer trickery.
1089
1090 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1091
1092 * alist.c (scm_acons): Use SCM{_SET}?_CELL_OBJECT as long as a
1093 cell is not known to be a valid pair.
1094
1095 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1096
1097 * eval.c (ASRTSYNTAX, scm_m_body, scm_m_letrec1): Removed
1098 ASRTSYNTAX. Using SCM_ASSYNT instead.
1099
1100 (scm_m_body): Don't create a redundant cons cell.
1101
1102 (scm_m_do): Removed redundant test 'bodycheck'.
1103
1104 (bodycheck): Removed.
1105
1106 * stacks.c (stack_depth, read_frame, read_frames): Removed
1107 redundant calculation of size, minimized some variable scopes.
1108
1109 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1110
1111 * pairs.c (scm_cons, scm_cons2): Use SCM{_SET}?_CELL_OBJECT as
1112 long as a cell is not known to be a valid pair.
1113
1114 (scm_pair_p): Eliminated redundant SCM_IMP test.
1115
1116 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1117
1118 * eval.c (scm_m_body, scm_macroexp, unmemocopy, scm_eval_args,
1119 scm_deval_args): Eliminated redundant SCM_IMP tests.
1120
1121 * hashtab.c (scm_ihashx, scm_sloppy_assx, scm_delx_x), weaks.c
1122 (scm_make_weak_key_hash_table, scm_make_weak_value_hash_table,
1123 scm_make_doubly_weak_hash_table): Fixed critical sections.
1124 Thanks to Keisuke Nishida.
1125
1126 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1127
1128 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest):
1129 Fixed some goto-related initialization bugs (introduced by me).
1130
1131 2000-05-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
1132
1133 * numbers.h (SCM_INUM0): Uses SCM_MAKINUM instead of SCM_PACK.
1134
1135 * dynl.c (dynl_obj, DYNL_OBJ, get_dynl_obj): Removed.
1136
1137 (DYNL_FILENAME, DYNL_HANDLE): Use SCM_CELL... macros instead of
1138 pointer trickery.
1139
1140 (SET_DYNL_HANDLE): Added.
1141
1142 (scm_dynamic_object_p): Simplified.
1143
1144 (scm_dynamic_unlink, scm_dynamic_func): Changed comment. Deliver
1145 better error message when accessing unlinked dynamic objects.
1146 Eliminated call to get_dynl_obj.
1147
1148 2000-05-03 Marius Vollmer <mvo@zagadka.ping.de>
1149
1150 * scmsigs.c (orig_handlers) [!HAVE_SIGACTION]: Fix declaration to
1151 be an array of function pointers instead of being a pointer to an
1152 array returning function. Thanks to Kalle Olavi Niemitalo!
1153
1154 2000-05-03 Dirk Herrmann <D.Herrmann@tu-bs.de>
1155
1156 * numbers.c (scm_divbigbig, scm_divbigint), numbers.h
1157 (scm_divbigbig, scm_divbigint): Don't return zero any more to
1158 indicate that a division has a remainder, return SCM_UNDEFINED
1159 instead. It is improbable that anyone actually used these
1160 functions outside of numbers.c. For this reason and due to the
1161 change in behaviour the functions are static now. Thus, if
1162 surprisingly there are users of these functions they will at least
1163 get alarmed.
1164
1165 * numbers.c: Removed #ifdef SCM_BIGDIG #endif in those functions,
1166 that already have a clean dispatch order. Note: SCM_BIGDIG is
1167 always defined.
1168
1169 * numbers.c (scm_inexact_p): Simplified.
1170
1171 * numbers.c (scm_num_eq_p, scm_less_p, scm_max, scm_min,
1172 scm_product, scm_num2dbl, scm_angle): Reordered dispatch
1173 sequence, thereby fixing some comparisons of SCM values with
1174 integer constants.
1175
1176 * numbers.c (scm_divide): Division by zero of inums leads to an
1177 error now. (Formerly, an infinite number was returned.)
1178
1179 Respect the fact, that scm_divbigbig does now return SCM_UNDEFINED
1180 if a division has a remainder.
1181
1182 2000-05-02 Gary Houston <ghouston@arglist.com>
1183
1184 * Makefile.am (INCLUDES): add ${INCLTDL} (thanks to Tim Mooney).
1185
1186 2000-05-02 Dirk Herrmann <D.Herrmann@tu-bs.de>
1187
1188 * numbers.c (scm_logtest, scm_division): Reordered dispatch
1189 sequence, thereby fixing some comparisons of SCM values with
1190 integer constants.
1191
1192 * numbers.h (scm_makdbl): Mark as deprecated at the point of
1193 declaration.
1194
1195 * eval.c (SCM_CEVAL, SCM_APPLY), gh_data.c (gh_double2scm,
1196 gh_doubles2scm), numbers.c (scm_istr2flo, scm_max, scm_min,
1197 scm_sum, scm_difference, scm_product, scm_divide, scm_sys_expt,
1198 scm_sys_atan2, scm_make_rectangular, scm_make_polar,
1199 scm_real_part, scm_imag_part, scm_magnitude, scm_angle,
1200 scm_long2num, scm_long_long2num, scm_ulong2num), ramap.c
1201 (ramap_rp, scm_array_map_x), random.c (scm_random,
1202 scm_random_uniform, scm_random_normal_vector_x, scm_random_exp),
1203 struct.c (scm_struct_ref), unif.c (scm_array_to_list): Replace
1204 call to scm_makdbl with a call to scm_make_real or
1205 scm_make_complex, depending on whether the imaginary part is known
1206 to be zero.
1207
1208 2000-05-01 Gary Houston <ghouston@arglist.com>
1209
1210 * scmsigs.c: fix the definition of orig_handlers for the case
1211 that HAVE_SIGACTION is not defined (thanks to
1212 Kalle Olavi Niemitalo).
1213
1214 * Makefile.am: remove include_HEADERS (was libguile.h)
1215 libguile.h: moved to top level directory.
1216
1217 2000-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1218
1219 * numbers.c (SCM_SWAP): Moved to the top of the file to allow for
1220 a wider use.
1221
1222 * numbers.c (scm_modulo, scm_gcd, scm_lcm, scm_logand, scm_logior,
1223 scm_logxor): Reordered dispatch sequence, thereby fixing some
1224 comparisons of SCM values with integer constants.
1225
1226 * number.c (scm_logtest): Removed some redundant SCM_{N}?IMP
1227 tests.
1228
1229 2000-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1230
1231 * numbers.c (scm_quotient, scm_remainder): Removed code that was
1232 conditionally compiled based on BADIVSGNS. BADIVSGNS does not
1233 occur anywhere else throughout guile.
1234
1235 * numbers.c (scm_quotient): Fixed parameter number in error
1236 message.
1237
1238 * numbers.c (scm_remainder): Reordered dispatch sequence.
1239
1240 2000-04-25 Gary Houston <ghouston@arglist.com>
1241
1242 * posix.c (scm_execlp): docstring fix (thanks to Martin
1243 Grabmueller).
1244
1245 2000-04-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
1246
1247 * eval.c (undef_object): Made into a local static variable
1248 (suggested by Jost Boekemeier).
1249
1250 2000-04-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
1251
1252 * pairs.c (cxrs, scm_init_pairs): Simplify initialization of
1253 c[ad]+r functions.
1254
1255 * procs.c (scm_init_iprocs), procs.h (scm_subr, scm_iproc,
1256 scm_dsubr, scm_init_iprocs): Removed.
1257
1258 * procs.h (SCM_SUBRF, SCM_DSUBRF): Access the cell words
1259 directly instead of casting a cell to a C struct.
1260
1261 2000-04-22 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1262
1263 Better modularization of GC extensions through new C level GC
1264 hooks:
1265
1266 * weaks.c (scm_weaks_prehistory): New function: Add
1267 scm_weak_vector_gc_init to scm_before_mark_c_hook; Add
1268 scm_mark_weak_vector_spines to scm_before_sweep_c_hook.
1269 (scm_scan_weak_vectors): New function; added to
1270 scm_after_sweep_c_hook.
1271
1272 * weaks.h (scm_weak_vectors, scm_weaks_prehistory): Added
1273 declarations.
1274
1275 * guardians.h (scm_guardian_gc_init, scm_guardian_zombify): Are
1276 now static.
1277
1278 * guardians.c (scm_guardian_gc_init): Turned into a hook function
1279 and added to scm_before_mark_c_hook.
1280 (scm_guardian_zombify): Turned into a hook function and added to
1281 scm_before_sweep_c_hook.
1282
1283 * async.c (scm_sys_gc_async_thunk): Run after-gc-hook.
1284 Added #include "libguile/gc.h".
1285
1286 * gc.h: Added #include "libguile/hooks.h".
1287
1288 * gc.c: Removed #include "libguile/guardians.h".
1289 (scm_before_gc_c_hook, scm_before_mark_c_hook,
1290 scm_before_sweep_c_hook, scm_after_sweep_c_hook,
1291 scm_after_gc_c_hook): New C level hooks.
1292 (scm_after_gc_hook): New Scheme level hook.
1293 (scm_gc_sweep): Moved scanning of weak vectors to weaks.c.
1294 (scm_igc): Moved initialization of scm_weak_vectors and the call
1295 to scm_guardian_gc_init to respective module.
1296 (scm_mark_weak_vector_spines): Moved to weaks.c;
1297 Call to scm_guardian_zombify moved to guardians.c;
1298 Run scm_before_gc_c_hook, scm_before_sweep_c_hook,
1299 scm_after_gc_c_hook at appropriate places.
1300 (scm_init_gc): Initialize scm_after_gc_hook.
1301
1302 * hooks.c, hooks.h (scm_make_hook_with_name): Removed deprecated
1303 function.
1304
1305 * init.c (scm_boot_guile_1): Added `scm_init_hooks'.
1306
1307 * Makefile.am: Added hooks.c, hooks.h, hooks.x.
1308
1309 * feature.c, feature.h: Broke out hook code into separate files.
1310
1311 * hooks.c, hooks.h: New files.
1312
1313 * *.*: Change includes so that they always use the "prefixes"
1314 libguile/, qt/, guile-readline/, or libltdl/.
1315 (Thanks to Tim Mooney.)
1316
1317 * Makefile.am (INCLUDES): Removed THREAD_CPPFLAGS and INCLTDL.
1318 (DEFS): Added. automake adds -I options to DEFS, and we don't
1319 want that.
1320 Removed all -I options except for the root source directory and
1321 the root build directory.
1322
1323 * numbers.c (scm_odd_p, scm_even_p): Use SCM_WRONG_TYPE_ARG
1324 instead of SCM_ASSERT (0, ...). (Some compilers will complain
1325 about control reaching end of function otherwise, and, besides,
1326 the new code is not less clear.)
1327
1328 * gc.c (scm_must_malloc, scm_must_realloc, scm_must_free): Added
1329 calls to malloc debugging functions.
1330
1331 * init.c (scm_boot_guile_1): Added calls to debug-malloc init
1332 functions.
1333
1334 * Makefile.am: Added debug-malloc.c, debug-malloc.h,
1335 debug-malloc.x.
1336
1337 * debug-malloc.c, debug-malloc.h: New files.
1338
1339 2000-04-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
1340
1341 * numbers.c (scm_exact_p, scm_odd_p, scm_even_p): Added
1342 documentation strings.
1343
1344 * numbers.c (scm_exact_p, scm_odd_p, scm_even_p, scm_abs,
1345 scm_quotient): Reordered dispatch sequence to first handle
1346 immediates, second handle bignums and finally handle generic
1347 functions respectively signal wrong type arguments. Hopefully
1348 this will allow for easier separation when goops is integrated.
1349
1350 2000-04-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
1351
1352 * gc.c (which_seg): Use SCM2PTR to convert a non immediate SCM
1353 variable into a pointer to a heap cell.
1354
1355 * gc.c (scm_mark_locations, scm_cellp, init_heap_seg,
1356 scm_unhash_name): Remove redundant cast to SCM_CELLPTR.
1357
1358 2000-04-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
1359
1360 * print.c (scm_iprin1): Don't assign zero to SCM values, use

1636
1637 * async.h: kill the scm_async_t struct. having a heap cell
1638 pretending to be a C struct is not helthy, and is not needed here

1641 * async.c: reflect the fact that asyncs are now represented by
1642 single heap cell each.

1708 * guardians.c (scm_guardian_zombify): mark all zombies in a
1709 separate loop after processing all the currently known live
1710 guardians, so as to not introduce order dependencies (thanks to
1711 Gary Houston). note that the order problems are still there if
1712 some guardians are themselves zombies, but that's a sick case that
1713 I'm not going to worry about.
1714 also, make another outer loop to process zombified
1715 guardians (which are uncovered while marking zombies).

1776 SRCPROPCOPY, SRCPROPPLIST), struct.c (scm_make_struct,
1777 scm_make_vtable_vtable): Use SCM_{SET_}?CELL_WORD* to access cell
1778 entries with raw data.
1779
1780 * gc.c (scm_init_storage), sort.c (applyless), strop.c
1781 (scm_string_to_list): Eliminate unnecessary casts to SCM.
1782
1783 * mallocs.c (scm_malloc_obj): Store result of malloc as raw
1784 data.
1785
1786 * ports.c (scm_close_all_ports_except): Duplicate documentation
1787 text removed.
1788
1789 * print.c (scm_iprin1): Use SCM_ITAG3.
1790
1791 * procs.h (SCM_SET_SUBRNUM): Fix shift direction.
1792
1793 * snarf.h (SCM_GPROC, SCM_GPROC1, SCM_SYMBOL, SCM_GLOBAL_SYMBOL,
1794 SCM_KEYWORD, SCM_GLOBAL_KEYWORD, SCM_VCELL, SCM_GLOBAL_VCELL,
1795 SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): Don't initialize globals
1796 and static variables at their point of declaration, but rather in
1797 the init function.
1798
1799 * tags.h (SCM_PACK): Automatically cast to scm_bits_t.
1800
1801 2000-04-02 Gary Houston <ghouston@arglist.com>
1802
1803 * guardians.c (TCONC_IN, scm_make_guardian): set the CDR of the
1804 empty tconc pair to SCM_EOL instead of SCM_BOOL_F, avoiding the
1805 use of an improper list (which breaks g_print. g_print isn't
1806 used).
1807 guardians.c: Added more comments and modified the make-guardian
1808 docstring. Reordered a few procedures.
1809
1810 2000-04-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
1811

1822 scm_reverse_lookup), dynl.c (scm_dynamic_link): Don't use C
1823 operators to compare SCM values.
1824
1825 * debug.c (scm_make_debugobj), debug.h (SCM_DEBUGOBJ_FRAME,
1826 SCM_SET_DEBUGOBJ_FRAME): Update SCM_{SET_}?DEBUGOBJ_FRAME to
1827 access raw cell data with SCM_{SET_}?CELL_WORD_1.
1828
1829 * debug.c (scm_make_debugobj): Don't use SCM_SETCAR to set types.
1830
1831 * debug.c (scm_make_memoized), dynl.c (scm_dynamic_link): Smob
1832 data is of type scm_bits_t.
1833
1834 2000-03-31 Dirk Herrmann <D.Herrmann@tu-bs.de>
1835
1836 * gdbint.c (gdb_maybe_valid_type_p), guardians.c (TCONC_EMPTYP,
1837 scm_guardian_zombify): Use SCM_EQ_P to compare SCM values.
1838
1839 * guardians.c (GUARDIAN): Use SCM_CELL_WORD_1 for raw data.
1840
1841 2000-03-31 Dirk Herrmann <D.Herrmann@tu-bs.de>
1842
1843 * ports.h (scm_port): Change type of stream member to scm_bits_t.
1844
1845 * gdbint.c (unmark_port, remark_port), ports.c (scm_markstream),
1846 strports.c (st_resize_port, scm_mkstrport), vports (sf_flush,
1847 sf_write, sf_fill_input, sf_close, scm_make_soft_port): Since
1848 streams are now of type scm_bits_t, SCM streams have to be
1849 unpacked/packed.
1850
1851 * ports.h (SCM_SETPTAB_ENTRY, SCM_SETSTREAM): Cast input to
1852 scm_bits_t.
1853
1854 2000-03-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1855
1856 * coop-defs.h (struct coop_t): Added `sto'-field again because of
1857 binary compatibility---let's remove it next time we alter some
1858 major structure.
1859
1860 * coop.c (coop_quitting_p, coop_cond_create, coop_mutex_create,
1861 coop_mother, coop_child): New variables.
1862 (mother): New function.
1863 (coop_create): New thread spawning mechanism which uses a "mother
1864 thread". The "dummy" pthreads aren't healthy enough to give birth
1865 to new threads since Linux threads thinks they are asleep.
1866
1867 * coop-defs.h (struct coop_t): Removed dummy_mutex.
1868
1869 * coop-defs.h, coop-threads.c (struct coop_t): Eliminate
1870 `sto'-field when GUILE_PTHREAD_COMPAT is enabled.
1871
1872 2000-03-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
1873
1874 * arbiters.c (scm_make_arbiter), async.c (scm_async), dynwind.c
1875 (scm_internal_dynamic_wind): Smob data is always of type
1876 scm_bits_t.
1877
1878 * arbiters.c (SCM_ARB_LOCKED, SCM_LOCK_ARB, SCM_UNLOCK_ARB):
1879 Access the locking information in cell entry 0 with
1880 SCM_{SET_}?CELL_WORD_0 instead of SCM_*CAR.
1881
1882 * async.c (scm_run_asyncs): Use SCM_NULLP to test for the empty
1883 list.
1884
1885 * dynwind.c (scm_dowinds): Use SCM_EQ_P to compare SCM values.
1886
1887 * ports.h (SCM_PTAB_ENTRY, SCM_SETPTAB_ENTRY): Access the ptab
1888 entry data using SCM_{SET_}?CELL_WORD_1 instead of SCM_{SET}?CDR.
1889
1890 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1891
1892 * alist.c (scm_sloppy_assq, scm_assq), eq.c (scm_eq_p, scm_eqv_p,
1893 scm_equal_p), list.c (scm_ilength, scm_last_pair, scm_reverse,
1894 scm_sloppy_memq, scm_delq_x, scm_delq1_x), tags.h (SCM_UNBNDP):
1895 Don't use C operators == and != to compare SCM values, use
1896 SCM_EQ_P instead.
1897
1898 * boolean.c (scm_boolean_p): Use SCM_BOOLP to determine whether a
1899 SCM value is equal to #t or #f.
1900
1901 * eq.c (scm_eqv_p, scm_equal_p): Don't use SCM_CAR to access the
1902 cell type entry of non immediate objects of unknown type. Use
1903 SCM_CELL_TYPE instead.
1904
1905 * gh_data.c (gh_scm2bool, gh_module_lookup), list.c
1906 (scm_sloppy_memv, scm_sloppy_member, scm_delv_x, scm_delete_x,
1907 scm_delv1_x, scm_delete1_x), scmsigs.c (scm_sigaction): Use
1908 SCM_FALSEP and SCM_TRUE_P to compare SCM values against #f and
1909 #t.
1910
1911 * list.c (scm_listify): Use SCM_UNBNDP to test for an unbound
1912 scheme value.
1913
1914 2000-03-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1915
1916 * coop-threads.c (scm_call_with_new_thread, scm_spawn_thread,
1917 scm_make_mutex, scm_make_condition_variable): Cast data to
1918 scm_bits_t in SCM_SET_CELL_WORD and SCM_NEWSMOB macros.
1919
1920 * coop.c (coop_create): Set `specific' field, not `data' to NULL.
1921
1922 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1923
1924 * smob.h (SCM_NEWSMOB, SCM_NEWSMOB2, SCM_NEWSMOB3, SCM_SMOB_DATA,
1925 SCM_SET_SMOB_DATA, SCM_TC2SMOBNUM, SCM_SMOBNUM): To access smob
1926 data, use SCM_{SET_}?CELL_TYPE or SCM_{SET_}?WORD_[1-3].
1927
1928 Note that this implies that smob data has always to be passed as
1929 values of type scm_bits_t.
1930
1931 2000-03-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1932
1933 * threads.c (scm_init_threads): Pass 0 size to scm_make_smob_type
1934 for scm_tc16_thread. As the current COOP threads are written, GC
1935 is not supposed to manage storage for threads.
1936
1937 * error.c (scm_error): Don't try to throw an error if
1938 scm_gc_heap_lock is true.
1939
1940 * coop.c (coop_finish): New function. Called at exit.
1941 (coop_aborthelp): Free thread structures when threads die.
1942 Finished LinuxThreads compatibility support => COOP threads now
1943 mesh with LinuxThreads.
1944
1945 * coop-threads.c (scm_call_with_new_thread, scm_spawn_thread):
1946 Changed SETCDR --> SET_CELL_WORD_1.
1947
1948 * coop-threads.c (scheme_launch_thread): Set word 1 of handle to 0
1949 when thread dies.
1950
1951 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1952
1953 * boolean.h (SCM_TRUE_P): New macro.
1954
1955 * boolean.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOLP), pairs.h
1956 (SCM_NULLP, SCM_NNULLP): Use SCM_EQ_P to compare SCM values.
1957
1958 2000-03-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1959
1960 * continuations.h (SCM_CONTREGS, SCM_SET_CONTREGS): New macros to
1961 access continuation data.
1962
1963 (SCM_SETJMPBUF): Deprecated. Use SCM_SET_CONTREGS instead.
1964
1965 (SCM_JMPBUF, SCM_DYNENV, SCM_THROW_VALUE, SCM_BASE, SCM_SEQ,
1966 SCM_DFRAME): Use SCM_CONTREGS instead of SCM_CHARS to access
1967 continuation data.
1968
1969 * continuations.c (scm_make_cont), init.c (start_stack),
1970 root.c (scm_internal_cwdr): Use SCM_SET_CONTREGS instead of
1971 SCM_SETJMPBUF.
1972
1973 2000-03-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1974
1975 * symbols.h (SCM_LENGTH, SCM_SETLENGTH): Access the length field
1976 of strings and symbols by using SCM_{SET_}?CELL_WORD_0.
1977
1978 (SCM_CHARS, SCM_UCHARS, SCM_SETCHARS): Use SCM_{SET_}?CELL_WORD_1
1979 to access the char * field of strings and symbols.
1980
1981 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
1982
1983 * gc.h (SCM_NEWCELL, SCM_NEWCELL2): Use SCM_SET_CELL_TYPE to set
1984 the type entry of a new cell. Added a comment about things to
1985 remember when updating the list of free cells.
1986
1987 (SCM_FREEP, SCM_MARKEDP): Use SCM_CELL_TYPE to access the type
1988 entry of a cell.
1989
1990 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
1991
1992 * pairs.h (SCM_CAR, SCM_CDR, SCM_SETCAR, SCM_SETCDR): Use
1993 SCM_CELL_OBJECT and SCM_SET_CELL_OBJECT. This change implies that
1994 with strict type checking enabled these macros will only work if
1995 given valid SCM parameters.
1996
1997 (SCM_GCCDR): Moved to tags.h.
1998
1999 * tags.h (SCM_GCCDR): Moved here from pairs.h.
2000
2001 2000-03-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
2002
2003 * tags.h (SCM2PTR, PTR2SCM): Moved to gc.h.
2004
2005 * pairs.h (scm_cell, SCM_CELLPTR, SCM_CELL_WORD*, SCM_CELL_OBJECT*,
2006 SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*, SCM_CELL_TYPE,
2007 SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK, SCM_PTR_GT,
2008 SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC, SCM_NEWCELL,
2009 SCM_NEWCELL2): Moved to gc.h.
2010
2011 (SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR, SCM_SETAND_CDR,
2012 SCM_SETOR_CAR, SCM_SETOR_CDR): Moved to gc.h. These names should
2013 be changed, though, since the macros are not only pair related.
2014
2015 (SCMPTR): Deleted.
2016
2017 * gc.h (SCM2PTR, PTR2SCM, scm_cell, SCM_CELLPTR, SCM_CELL_WORD*,
2018 SCM_CELL_OBJECT*, SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*,
2019 SCM_CELL_TYPE, SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK,
2020 SCM_PTR_GT, SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC,
2021 SCM_NEWCELL, SCM_NEWCELL2, SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR,
2022 SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR): Moved here from
2023 tags.h and pairs.h.
2024
2025 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2026
2027 * tags.h (SCM_STRICT_TYPING): New macro that, if defined,
2028 activates strict compile time type checking for variables of
2029 type SCM.
2030 (SCM, SCM_PACK, SCM_UNPACK): Define according to whether
2031 SCM_STRICT_TYPING or SCM_VOIDP_TEST are defined.
2032 (SCM_EQ_P): Defined as a macro equivalent for eq?.
2033
2034 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2035
2036 * tags.h (SCM_POINTERS_MUNGED): Removed.
2037
2038 * gc.c (scm_gc_sweep, init_heap_seg): Removed use of
2039 SCM_POINTERS_MUNGED, thus fixing some illegal casts to SCM.
2040
2041 2000-03-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
2042
2043 * pairs.h (SCM_CELL_OBJECT, SCM_CELL_OBJECT_[0-3],
2044 SCM_SET_CELL_OBJECT, SCM_SET_CELL_OBJECT_[0-3], SCM_CELL_TYPE,
2045 SCM_SET_CELL_TYPE): Added a set of low level macros for accessing
2046 cell entries.
2047 (SCM_CELL_WORD_[0-3]): Renamed from the SCM_CELL_WORD[0-3].
2048
2049 * procs.h, procs.c: Instead of SCM_{SET_}?CELL_WORD[12], use the
2050 newly introduced SCM_{SET_}?CELL_OBJECT_[12] macros.
2051
2052 2000-03-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2053
2054 * tags.h: Disabled definition of SCM_VOIDP_TEST.
2055
2056 Defining SCM as void * introduces problems which haven't been
2057 handled yet. Developers who work with these issues can enable it
2058 in their working copies.
2059
2060 Disabling this definition exposes a set of newly introduced and
2061 older misuses of types which causes warning messages during
2062 compilation. We'll fix this successively.
2063
2064 * gc.c (scm_mark_locations): Changed * (SCM **) X --> * (SCM *) X
2065 in order to obtain a value of type SCM.
2066 (scm_cellp): Updated with new changes to scm_mark_locations.
2067
2068 * continuations.h (SCM_SETJMPBUF): Cast second arg into SCM.
2069
2070 * continuations.c (scm_make_cont): Removed cast of size_t into
2071 long.
2072
2073 * symbols.h (SCM_SETCHARS): Cast second arg into SCM.
2074
2075 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
2076
2077 * numbers.h (SCM_SETNUMDIGS): Use SCM_BIGSIZEFIELD macro for
2078 shifting, not constant. Thanks to Dale P. Smith.
2079
2080 * numbers.c (scm_sum, scm_difference): Don't test a SCM value
2081 for being less than zero. Decode it to a C value first. Again,
2082 thank you Dale.
2083
2084 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
2085
2086 * numbers.h, ramap.c, struct.h, vectors.h: Don't use SCM2PTR for
2087 non scheme values. If raw data is stored in SCM variables, it has
2088 to be accessed using SCM_UNPACK until a better solution is found.
2089
2090 2000-03-22 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2091
2092 * tags.h (SCM_ECONSP, SCM_NECONSP): More corrections of
2093 pointer-arithmetic induced by the SCM_PACK/UNPACK change.
2094
2095 * print.c (scm_iprin1): SCM_PACK/UNPACK corrections.
2096
2097 * gc.c (scm_gc_sweep): SCM_PACK/UNPACK corrections.
2098
2099 * eval.c (SCM_CEVAL, scm_unmemocar): SCM_PACK/UNPACK corrections.
2100
2101 * dynwind.c (scm_swap_bindings): SCM_PACK/UNPACK corrections.
2102
2103 * async.c, __scm.h: Removed lots of the old async click logic. It
2104 is possible to reinsert it by defining GUILE_OLD_ASYNC_CLICK in
2105 __scm.h. Let's try this out and dump the old code after the
2106 threads reorganization.
2107 (set-tick-rate, set-switch-rate): Conditionally removed.
2108
2109 2000-03-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2110
2111 * gc.c (scm_gc_mark): Bugfix 1: The recent SCM_PACK/UNPACK change
2112 made SCM values into pointers. This turned an arithmetic
2113 computation of the address of the vcell into a pointer-arithmetic
2114 one, thereby screwing up marking of structs.
2115 Bugfix 2: Removed incompletely introduced loop variable `j' used
2116 when protecting the tail array of a struct.
2117
2118 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2119
2120 * struct.h (SCM_STRUCT_DATA): Don't cast SCM values to pointers.
2121
2122 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2123
2124 * symbols.h, symbols.c (scm_strhash): Declare the string
2125 parameter as constant, since it is not modified.
2126
2127 * symbols.c (scm_intern_obarray_soft,
2128 scm_sysintern0_no_module_lookup): Can now pass constant strings
2129 to scm_strhash without need for casting.
2130
2131 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2132
2133 * vectors.h (SCM_VELTS, SCM_VELTS_AS_STACKITEMS): Don't cast SCM
2134 values to pointers. Use SCM2PTR instead.
2135
2136 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2137
2138 * async.c (scm_set_tick_rate, scm_set_switch_rate): Don't unpack
2139 results of SCM_INUM.
2140
2141 2000-03-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2142
2143 * init.c (scm_boot_guile_1): Renamed GUILE_GC_TRIGGER_1 -->
2144 GUILE_MIN_YIELD_1, GUILE_GC_TRIGGER_2 --> GUILE_MIN_YIELD_2.
2145 GUILE_MIN_YIELD_X now take *positive* fractions of heap size.
2146
2147 * gc.c, gc.h (SCM_MIN_YIELD_1, SCM_MIN_YIELD_2,
2148 min_yield_fraction, min_yield, adjust_min_yield): Renamed from
2149 SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2, gc_trigger_fraction,
2150 gc_trigger, adjust_gc_trigger.
2151
2152 * gc.c (alloc_some_heap): Further improvement of minimal heap size
2153 prediction.
2154 (SCM_MAX): New macro.
2155 (scm_freelist_t): New field: collected_1. Previous amount of
2156 collected cells.
2157 (gc_sweep_freelist_finish): Trigger based on two last values of
2158 freelist->collected to avoid unnecessary allocation due to
2159 temporary peaks.
2160 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2):
2161 Adjusted to 45000 cells, 40% and 40%. Gives quick startup
2162 without extra heap allocation.
2163
2164 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2165
2166 * numbers.h (SCM_MAKINUM): The parameter to SCM_MAKINUM should
2167 already be a C value. No need to unpack it.
2168
2169 * numbers.c (scm_long_long2num): Cast the parameter to scm_bits_t
2170 if we know it fits into an inum.
2171
2172 * ramap.c (ramap_rp): An scm_tc7_[ui]vect object does point to a
2173 field of long values. In contrast, SCM_VELTS accesses a field of
2174 SCM values.
2175
2176 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2177
2178 * gc.c (scm_gc_stats): Inserted explanation of local_scm_mtrigger
2179 etc.
2180 (scm_gc_yield_1): New variable: Holds previous yield. Used to
2181 make better judgements.
2182 (gc_sweep_freelist_finish): Inserted explanation of use of
2183 gc_trigger.
2184
2185 * print.h, stacks.h, options.c, options.h: Changed C++
2186 commentaries to C.
2187
2188 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2189
2190 * tags.h (SCM2PTR, PTR2SCM): Use SCM_PACK / SCM_UNPACK correctly.
2191
2192 * numbers.h (SCM_INUMP, SCM_MAKINUM, SCM_INUM0, SCM_COMPLEX_REAL,
2193 SCM_COMPLEX_IMAG, SCM_NUMP, SCM_BDIGITS): Use SCM_PACK /
2194 SCM_UNPACK / SCM2PTR correctly.
2195
2196 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2197
2198 * gc.c (adjust_gc_trigger): Improved documentation.
2199 (alloc_some_heap): Since gc_trigger is used against
2200 freelist->collected, this is the value which should be used to
2201 predict minimum growth.
2202
2203 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2204
2205 * eval.h: Fix mixup of packed/unpacked SCM values. (Thanks
2206 Thien-Thi Nguyen for the patch.)
2207
2208 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2209
2210 * numbers.c (scm_ash): Fixed typing problems with the second
2211 parameter and added some documentation. (Thanks Thien-Thi Nguyen
2212 for indicating the problem.)
2213
2214 2000-03-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2215
2216 * gc.c, gc.h (scm_gc_yield): New variable.
2217 (adjust_gc_trigger): Use scm_gc_yield.
2218 (alloc_some_heap): Use scm_gc_yield instead of
2219 scm_gc_cells_collected.
2220
2221 * coop-threads.c: Addd #include "root.h", #include "strings.h".
2222
2223 * debug.c: Added #include "root.h". (Thanks to Thien-Thi Nguyen.)
2224
2225 * gc.c (scm_gc_for_newcell, adjust_gc_trigger): Improved GC
2226 trigger adjustmeant: Take yield (freed cells) for all freelists
2227 into account.
2228 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Tuned
2229 to 50000 cell heap with 45% trigger.
2230 (scm_gc_cells_collected): Reintroduced.
2231 (SCM_HEAP_SIZE): New macro.
2232 (scm_gc_sweep): Reintroduced correct computation of
2233 scm_cells_allocated.
2234 (scm_freelist_t): Corrected commentary for field `cluster_size':
2235 Clustersize counts objects, not cells; New member
2236 `clusters_allocated'.
2237
2238 2000-03-19 Michael Livshin <mlivshin@bigfoot.com>
2239
2240 * *.[hc]: add Emacs magic at the end of file, to ensure GNU
2241 indentation style.
2242
2243 2000-03-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2244
2245 * threads.h: Added #include "libguile/throw.h". (Thanks to
2246 Thien-Thi Nguyen.)
2247
2248 2000-03-18 Michael Livshin <mlivshin@bigfoot.com>
2249
2250 * tags.h: (SCM_DOUBLE_CELLP, SCM_NDOUBLE_CELLP): new macros (bad
2251 names, anyone got any better ones?)
2252
2253 * gc.h: (typedef struct scm_freelist_t) remove from here.
2254
2255 * gc.c: (CELL_UP, CELL_DN) made these macros take additional
2256 parameter (the span).
2257 (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK) new macros.
2258 (typedef struct scm_freelist_t) moved here from gc.h, it had no
2259 business being externally visible.
2260 (typedef struct scm_heap_seg_data_t) renamed from
2261 scm_heap_seg_data, to be style-compliant.
2262 (scm_mark_locations) if the possible pointer points to a
2263 double-cell, check that it's properly aligned.
2264 (init_heap_seg) align double-cells properly, work with the
2265 assumption that the segment size divides cleanly by cluster size.
2266 (round_to_cluster_size) new function.
2267 (alloc_some_heap, make_initial_segment) use round_to_cluster_size
2268 to satisfy the new init_heap_seg invariant.
2269
2270 2000-03-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
2271
2272 * _scm.h: Don't include async.h everywhere...
2273

2326
2327 2000-03-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2328
2329 * gc.c, gc.h: Cleanup of the change of 2000-03-15.
2330 Cluster sizes are now independent of GC trigger values.
2331 GUILE_GC_TRIGGER_n can now specify a relative trigger value:
2332 A negative integer gives fraction of total heap size in percent.
2333 (SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Default values set to -40.
2334
2335 * init.c (scm_boot_guile_1): Introduced new variable
2336 GUILE_MAX_SEGMENT_SIZE; New environment variable names:
2337 GUILE_INIT_SEGMENT_SIZE_1, GUILE_GC_TRIGGER_1,
2338 GUILE_INIT_SEGMENT_SIZE_2, GUILE_GC_TRIGGER_2
2339
2340 2000-03-16 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2341
2342 * __scm.h (GC_FREE_SEGMENTS): Disable this until we have made
2343 freeing of segment work with the new GC scheme. (Thanks to
2344 Michael Livshin.) Oops, also happened to make GUILE_NEW_GC_SCHEME
2345 the default, but I'll let this change stay in CVS Guile since this
2346 code is not expected to contain serious bugs.
2347
2348 2000-03-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2349
2350 * gc.c, gc.h (scm_map_free_list): Define also if GUILE_DEBUG is
2351 defined.
2352 (scm_free_list_length): New procedure (GUILE_DEBUG).
2353 Fixed a small but serious bug introduced by the previous change.
2354
2355 * gc.c (scm_gc_sweep): Moved variable n_objects to inner sweep
2356 loop and declare as register.
2357
2358 * gc.c (scm_gc_sweep): Sigh... forgot to clear private freelists
2359 after GC.
2360
2361 Wed Mar 15 08:27:04 2000 Greg J. Badros <gjb@cs.washington.edu>
2362
2363 * fluids.c: Docstring patch from Keisuke Nishida. Some
2364 reindentation, too, and a couple formals renamed. Should
2365 fluid-set! return UNSPECIFIED instead of a value?
2366
2367 Wed Mar 15 08:24:58 2000 Greg J. Badros <gjb@cs.washington.edu>
2368
2369 * Makefile.am: Separate out DOT_X_FILES and DOT_DOC_FILES, and
2370 generate the latter from the concrete listing of the former. Then
2371 make guile-procedures.txt depend on DOT_DOC_FILES instead of
2372 *.doc, so that rebuilding it works.
2373
2374 Wed Mar 15 08:12:14 2000 Greg J. Badros <gjb@cs.washington.edu>
2375
2376 * libguile.h: Include libguile/validate.h. Thanks Keisuke Nishida!
2377
2378 * guile-snarf.awk.in: Replace docstring line-ending \n" and \n\n"
2379 with nothing and \n, respectively. Thanks Keisuke Nishida for
2380 noticing this problem.
2381
2382 2000-03-15 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2383
2384 * __scm.h (GUILE_NEW_GC_SCHEME): Define this if you want to test a
2385 new way of allocating heap. It makes Guile fast, but still
2386 contains bugs.
2387
2388 * gc.c, gc.h, pairs.h, init.c: Implementation of a new way of
2389 allocating heap. The basic idea is to trigger GC every Nth
2390 allocated cell and grow heap when free list runs out. The scheme
2391 has been extended so that GC isn't triggered until all remaining
2392 cells are used. The implementation is also prepared for
2393 development in the direction of POSIX threads.
2394
2395 * gc.c (SCM_EXPHEAP): In order to grow by a factor of 1.5,
2396 SCM_EXPHEAP should return half of the heap size.
2397
2398 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2399
2400 The following change to init.c is only enabled if Guile was
2401 configured with --enable-guile-debug.
2402
2403 * init.c (scm_i_getenv_int): New function.
2404 (scm_boot_guile_1): Use the environment variables
2405 GUILE_INIT_HEAP_SIZE, GUILE_INIT_HEAP_SIZE2 to select heap size if
2406 they exist. (This may be replaced by a Scheme level mechanism in
2407 the future.)
2408
2409 * objprop.c (s_scm_set_object_property_x): Use scm_assq instead of
2410 scm_assoc. (Thanks to Keisuke Nishida.)
2411
2412 2000-03-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2413
2414 * eval.c, lang.c, lang.h (scm_lisp_nil, scm_lisp_t): Renamed from
2415 scm_nil, scm_t. (Thanks to Keisuke Nishida.)
2416
2417 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2418
2419 * init.c (scm_boot_guile_1): Use same initial segment size for
2420 1-word and 2-word segments. Having the smaller size causes Guile
2421 to GC too often. Obviously something needs to be done to allow
2422 for a smaller 2-word segment without this to happen. (The amount
2423 of heap for each type should be automatically adapted to the
2424 application somehow.)
2425
2426 [Almost all of these changes should be documented in the NEWS
2427 file.]
2428
2429 * gc.h (scm_freelist_t): New type.
2430
2431 * pairs.h (SCM_NEWCELL, SCM_NEWCELL2): Use new style freelists.
2432
2433 * gc.c (SCM_INIT_HEAP_SIZE): Changed from 32768 --> 40000 so that
2434 all of Guile basics fits into one segment and there suitable room
2435 for work.
2436 (SCM_EXPHEAP): Now takes an argument. Grow by a factor of 1.5
2437 instead of 2.
2438 (scm_freelist, scm_freelist2): Now of type scm_freelist_t.
2439 Freelists now contains information about object span, cells
2440 collected and amount of cells in heap segments belonging to the
2441 list.
2442 (scm_heap_size, scm_gc_cells_collected): Removed.
2443
2444 * init.c (scm_boot_guile_1): Make 2-word segment 8K (512 cells).
2445
2446 * Makefile.am (libguile_la_LDFLAGS): Bumped library version
2447 number.
2448
2449 * __scm.h eq.c, eval.c, gc.c, gc.h, gh_data, hash.c, numbers.c,
2450 numbers.h, objects.c, ramap.c, random.c, unif.c, unif.h: Extensive
2451 rewrite of handling of real and complex numbers.
2452 (SCM_FLOATS, SCM_SINGLES): These #ifdef conditionals have been
2453 removed along with the support for floats. (Float vectors are
2454 still supported.)
2455
2456 * tags.h (scm_tcs_bignums): Removed.
2457 (scm_tc16_bigpos, scm_tc16_bigneg): Replaced by scm_tc16_big.
2458 Use SCM_BIGSIGN(x) to test for sign!
2459 (scm_tc16_big): The new bignum type.
2460 (SCM_REAL_PART, SCM_IMAG_PART): Removed.
2461
2462 * numbers.h (SCM_BIGSIGN): Sign moved to bit 16.
2463 (scm_makdbl): Deprecated.
2464 (SCM_NEWREAL, SCM_NEWCOMPLEX): New macros.
2465 (SCM_SINGP): Deprecated.
2466 (SCM_FLO): Removed.
2467 (SCM_INEXP, SCM_CPLXP): Deprecated.
2468 (SCM_INEXACTP, SCM_COMPLEXP): New macros.
2469 (SCM_COMPLEX_REAL, SCM_COMPLEX_IMAG): Renamed from
2470 SCM_REAL, SCM_IMAG (and now only valid for complex numbers).
2471 (SCM_REAL, SCM_IMAG): New, *deprecated*, selectors which work both
2472 for doubles and complex numbers.
2473 (SCM_REAL_VALUE): New selector for doubles.
2474 (scm_double_t, scm_complex_t): New types.
2475 (scm_dbl): Removed.
2476
2477 * numbers.c (scm_floprint, scm_floequal): Removed.
2478 (scm_print_real, scm_print_complex, scm_real_equalp,
2479 scm_complex_equalp): New functions.
2480
2481 * unif.c (scm_makflo): Removed.
2482
2483 * smob.h (SCM_SMOB_PREDICATE): New macro.
2484 (SCM_NEWSMOB2, SCM_RETURN_NEWSMOB2, SCM_NEWSMOB3,
2485 SCM_RETURN_NEWSMOB3): New macros.
2486
2487 1999-11-21 Michael Livshin <mlivshin@bigfoot.com>
2488
2489 The following changes implement primitive support for double cells
2490 (i.e. four-word cells) and change the representation of some
2491 things to multi-cells instead of cons+malloc. (Applied and
2492 modified by mdj.)
2493
2494 * pairs.h (SCM_NEWCELL2): double-cell variants of SCM_NEWCELL.
2495 (SCM_CELL_WORD, SCM_CELL_WORDLOC, SCM_SET_CELL_WORD): primitive
2496 multi-cell access macros (used by the ones below).
2497 (SCM_CELL_WORD[0-3], SCM_SET_CELL_WORD[0-3]): multi-cell access
2498 macros.
2499
2500 * gc.c (scm_freelist2): multi-cell freelists.
2501 (inner_map_free_list): map_free_list, parameterized on ncells.
2502 "nn cells in segment mm" was misleading for ncells > 1; changed to
2503 "objects". still print cells too, though.
2504 (scm_map_free_list): rewritten using inner_map_free_list.
2505 (scm_check_freelist): get freelist as parameter, since now we have
2506 more than one.
2507 (scm_debug_newcell2): multi-cell variants of
2508 scm_debug_newcell.
2509 (scm_gc_for_newcell): take ncells and freelist pointer as
2510 parameters.
2511 (scm_gc_mark): add case for tc7_pws (procedures with setters are
2512 now double cells).
2513 (scm_gc_sweep): don't free the float data, since it's not malloced
2514 anymore.
2515 (init_heap_seg): didn't understand what n_new_objects stood for,
2516 so changed to n_new_cells.
2517 (make_initial_segment): new function, makes an initial segment
2518 according to given ncells.
2519 (scm_init_storage): call make_initial_segment, for ncells={1,2,3}.
2520
2521 * numbers.c (scm_makdbl): no malloc'ing needed, so the
2522 {DEFER,ALLOW}_INTS thing removed.
2523
2524 * numbers.h (struct scm_dbl): changed to represent a double cell,
2525 with the number in the second half.
2526
2527 * dynwind.c: changed the wind-guards representation to double
2528 cell.
2529
2530 * procs.c, procs.h: changed the procedure-with-setter representation
2531 to double cell.
2532
2533 * async.c, async.h: made async representation a double cell.
2534
2535 * dynl.c: made dynamic_obj representation a double cell.
2536
2537 2000-03-13 Gary Houston <ghouston@arglist.com>
2538
2539 * ports.c (flush_void_port): renamed to flush_port_default.
2540 (end_input_void_port): renamed to end_input_default.
2541
2542 * init.c (scm_standard_stream_to_port): create a void port instead
2543 of opening /dev/null if the standard file descriptors are bad.
2544 advantages: no portability problems, doesn't waste a file descriptor,
2545 simplifies the code (thanks to Marius for the idea).
2546
2547 * vports.c (s_scm_make_soft_port): call scm_port_non_buffer.
2548
2549 * void ports: make reading from a void port give EOF instead of
2550 segv:
2551 * ports.c (s_scm_sys_make_void_port): modified docstring.
2552 (fill_input_void_port): new proc.
2553 (scm_init_ports): set up fill_input_void_port.
2554 * ports.c (scm_port_non_buffer): new proc.
2555 (scm_void_port): call scm_port_non_buffer.
2556
2557 * fports.c (scm_setvbuf): docstring: remove the fcntl documentation
2558 which was incorrectly appended.
2559
2560 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2561
2562 * guile-doc-snarf.in: Don't use absolute path for `sed'. (Note
2563 that we can't use autoconf for this. Autoconf itself relies on
2564 the existence of `sed' somewhere on your path.) (Thanks to Dirk
2565 Herrman.)
2566
2567 2000-03-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2568
2569 * Makefile.am (libguile_la_SOURCES): Moved iselect.c here from
2570 EXTRA_libguile_la_SOURCES.
2571
2572 * iselect.h: Always declare scm_internal_select.
2573
2574 * iselect.c (scm_internal_select): Added SCM_ASYNC_TICK at the
2575 end. Also let scm_internal_select be a real function also when
2576 not using threads.
2577
2578 * __scm.h (SCM_TICK): Oops! Forgot to put SCM_ASYNC_TICK here...
2579
2580 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2581
2582 * __scm.h (SCM_ALLOW_INTS, SCM_REALLOW_INTS): Removed call to
2583 SCM_ASYNC_TICK. (This is a preparation for POSIX threads support,
2584 and kind of an experiment: Will this cause problems?)
2585
2586 Sun Mar 12 13:26:30 2000 Greg J. Badros <gjb@cs.washington.edu>
2587
2588 * Makefile.am: Added *.doc to DISTCLEANFILES.
2589
2590 2000-03-12 Gary Houston <ghouston@arglist.com>
2591
2592 * fports.c (scm_fdes_to_port): call fcntl F_GETFL to test that
2593 the fdes is valid before doing anything else. check that
2594 the file descriptor supports the modes required.
2595 (scm_fport_buffer_add): don't throw an error if fstat doesn't
2596 work: just use the default buffer size.
2597
2598 * throw.c: change an outdated comment about scm_internal_catch
2599 BODY: it doesn't take a jumpbuf arg.
2600
2601 * init.c (scm_standard_stream_to_port): install a handler in case
2602 scm_fdes_to_port throws an error. don't check here whether the
2603 file descriptor is valid, since scm_fdes_to_port will do that.
2604 set the revealed count depending on whether the port got the
2605 standard file descriptor.
2606 (stream_body_data): new type.
2607 (stream_body, stream_handler): new procs.
2608
2609 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2610
2611 * stacks.c, stacks.h, struct.c, tags.h, unif.c (scm_bits_t):
2612 Renamed from SCMWORD.
2613
2614 * tags.h (SCM_NCELLP): Removed (SCMWORD).
2615
2616 * arbiters.c (SCM_ARB_LOCKED): Use SCM_UNPACK_CAR.
2617
2618 * async.c, boolean.h, debug.c, dynl.c, dynwind.c, eval.c, eval.h,

2625 weaks.h (SCM_PACK, SCM_UNPACK, SCM_UNPACK_CAR): Renamed from
2626 SCM_ASSCM, SCM_ASWORD, SCM_CARW).
2627
2628 * numbers.h (SCM_SRS, SCM_INUM): Corrected SCM_ASSCM/ASWORD fixes.
2629
2630 * alist.c, eval.c, net_db.c, posix.c, print.c, snarf.h, struct.c,
2631 tags.h: Fixed copyright notices.
2632
2633 * struct.c, coop-threads.c: SCM_ASSCM/ASWORD fixes.
2634
2635 2000-03-12 Marius Vollmer <mvo@zagadka.ping.de>
2636
2637 * init.c (scm_standard_stream_to_port): Check whether the file
2638 descriptor is valid and substitute "/dev/null" when not.
2639
2640 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2641
2642 * coop-defs.h (struct timespec): Conditionally defined.
2643
2644 * coop.c (coop_condition_variable_timed_wait_mutex): Use ETIMEDOUT
2645 instead of ETIME.
2646
2647 * readline.c (match_paren): Bugfix: First arg to select is not
2648 number of descriptors but the number of the highest descriptor +
2649 1.
2650
2651 This is a preliminary attempt at a cleanup of the threads support
2652 code. It moves things to better places, makes arguments more
2653 consistent with the POSIX API (which is used in GNOME's glib), and
2654 adds new functionality.
2655
2656 * readline.c (scm_init_readline): Added new arg to scm_init_mutex.
2657
2658 * coop-defs.h (scm_mutex_trylock): New macro: alias for
2659 coop_mutex_trylock.
2660 (scm_cond_init): Changed definition to
2661 coop_new_condition_variable_init.
2662
2663 * coop.c: #include <errno.h>
2664 (coop_timeout_qinsert): Moved here from iselect.c
2665 (coop_new_mutex_init, coop_new_condition_variable_init): New
2666 functions. The strange names are temporary. Use scm_mutex_init
2667 and scm_cond_init instead.
2668 (coop_mutex_trylock): New function. Uses errno.h:EBUSY. errno.h
2669 is ANSI C, but should we check for individual error codes in
2670 configure.in?
2671 (coop_condition_variable_timed_wait_mutex): New function.
2672 (coop_key_create, coop_setspecific, coop_getspecific,
2673 coop_key_delete): New functions.
2674
2675 * iselect.c (coop_timout_qinsert): Moved to coop.c
2676
2677 2000-03-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2678
2679 * pairs.h (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR,
2680 SCM_SETOR_CDR): Corrected SCM_ASSCM/WORD fixes.
2681
2682 * tags.h (SCM_VOIDP_TEST): Renamed from VOIDP_TEST.
2683 Layout cleanups.
2684
2685 * objects.h (SCM_CLASS_FLAGS, SCM_OBJ_CLASS_FLAGS,
2686 SCM_SET_CLASS_INSTANCE_SIZE), struct.h (SCM_STRUCT_VTABLE_DATA),
2687 proc.h (SCM_CLOSCAR): SCM_ASSCM/WORD fixes.
2688
2689 * eval.c (scm_lookupcar1): Inserted SCM_ASWORD in expressions
2690 dealing with ilocs.
2691
2692 2000-03-11 Dale P. Smith <dpsm@en.com>, applied by Greg J. Badros, <gjb@cs.washington.edu>
2693
2694 * numbers.c (scm_copy_big_dec, scm_copy_smaller, scm_big_ior,
2695 scm_big_xor, scm_big_and, scm_big_test): Added new lowlevel bignum
2696 logical functions from SCM.
2697
2698 (logand, logior, logxor, logtest, logbit?): Extended scheme
2699 logical functions to use bignums from SCM.
2700
2701 (lognot): Removed call to `SCM_VALIDATE_INUM' that prevented
2702 lognot from using bignums.
2703
2704 Thu Mar 9 11:33:25 2000 Greg J. Badros <gjb@cs.washington.edu>
2705
2706 * vectors.h (SCM_VELTS_AS_STACKITEMS): Added this macro to help in
2707 eliminating some warnings.
2708
2709 * unif.c, strports.c, print.c, options.c: Fix some warnings on
2710 mis-use of SCM/long
2711
2712 * gc.c, gc.h: Added scm_return_first_int(), and added comment re:
2713 what the scm_return_first* functions do.
2714
2715 2000-03-09 Han-Wen Nienhuys <hanwen@cs.uu.nl>, applied by Greg J. Badros, <gjb@cs.washington.edu>
2716
2717 * libguile/*.[ch]: make a distinction between SCM as a generic
2718 name for a Scheme object (now a void*), and SCM as 32 bit word for
2719 storing tags and immediates (now a long int). Introduced
2720 SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious
2721 code in the process: arbiter.c (use macros), unif.c (scm_array_p),
2722
2723 Wed Mar 8 10:15:59 2000 Greg J. Badros <gjb@cs.washington.edu>
2724
2725 * numbers.c: Use SCM_VALIDATE_LONG_COPY, and longs, not ints, in
2726 various logXXX primitives. Thanks Eric Moore!
2727
2728 Tue Mar 7 08:05:22 2000 Greg J. Badros <gjb@cs.washington.edu>
2729
2730 * run-test, remaining-docs-needed: Added these scripts. The
2731 second one is only temporary until the docstring additions are
2732 complete. run-test may best live on, but is here mostly for
2733 convenience and awareness for now.
2734
2735 * hash.c: Docs, minor cleanup patch from Dirk Herrman.
2736
2737 Thu Mar 2 16:06:58 2000 Greg J. Badros <gjb@cs.washington.edu>
2738
2739 * error.h, error.c: Added `scm_wrong_type_arg_msg' to support
2740 displaying the expected type. Use SCM_LISTn in a couple places
2741 instead of scm_cons-ing by hand.
2742
2743 * __scm.h: Added SCM_ASSERT_TYPE macro.
2744
2745 * validate.h, scm_validate.h: Added the former, as a renamed
2746 version of the latter with SCM_ASSERT_TYPE used in
2747 SCM_MAKE_VALIDATE (instead of just SCM_ASSERT)
2748
2749 * Makefile.am: Rename scm_validate.h to validate.h.
2750
2751 * *.c, *.h: Include validate.h, not scm_validate.h (old name's
2752 prefix was superfluous).
2753
2754 Thu Mar 2 15:33:12 2000 Greg J. Badros <gjb@cs.washington.edu>
2755
2756 * hashtab.c: Improved documentation for lots of functions. Added
2757 handwritten docs for `hash-fold'.
2758
2759 Thu Mar 2 15:13:25 2000 Greg J. Badros <gjb@cs.washington.edu>
2760
2761 * list.c: Added hand-written docs for `del{q,v,ete}1!'.
2762
2763 Thu Mar 2 12:38:30 2000 Greg J. Badros <gjb@cs.washington.edu>
2764
2765 * list.c: Moved append docs to append! Thanks Dirk Hermann. Also,
2766 added append docs from R4RS.
2767
2768 * strings.c: Docstring typo fix, + eliminate unneeded IMP tests.
2769 Thanks Dirk Hermann!
2770
2771 * chars.h: Provide SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR and
2772 deprecate SCM_ICHRP, SCM_ICHR, SCM_MAKICHR. Thanks Dirk Hermann!
2773
2774 * *.h, *.c: Use SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR throughout.
2775 Drop use of SCM_P for function prototypes... assume an ANSI C
2776 compiler. Thanks Dirk Hermann!
2777
2778 Sat Feb 19 12:20:12 2000 Greg J. Badros <gjb@cs.washington.edu>
2779
2780 * ports.c: Made `set-port-column!' and `set-port-line!' each
2781 return SCM_UNSPECIFIED instead of a (not-scheme-object) integer
2782 that caused a seg fault. Also fixed `set-port-column!'s
2783 docstring. Thanks Han-Wen Nienhuys for finding the bug!
2784
2785 Sun Feb 13 19:11:42 2000 Greg J. Badros <gjb@cs.washington.edu>
2786
2787 * arbiters.c, eq.c, gc.c, guardians.c, list.c, ports.c, print.c,
2788 regex-posix.c, scmsigs.c, stime.c, strings.c, variable.c, stime.c,
2789 strings.c, variable.c: Added lots of documentation, cleaned up
2790 some existing documentation. Occasionally changed formal params
2791 to match docs. Also folded an #ifdef into the inners of a
2792 primitive instead of having two copies of the primitive
2793 (`get-internal-real-time', from stime.c)
2794
2795 Sun Feb 13 18:12:19 2000 Greg J. Badros <gjb@cs.washington.edu>
2796
2797 * ports.c: Added docs for primitives missing them. Written by
2798 hand.
2799
2800 Sun Feb 13 09:40:36 2000 Greg J. Badros <gjb@cs.washington.edu>
2801
2802 * guile-doc-snarf.in: Use ${AWK} -f guile-func-name-check, not
2803 just execing guile-func-name-check. Thanks Michael Livshin!
2804
2805 Thu Feb 10 11:43:23 2000 Greg J. Badros <gjb@cs.washington.edu>
2806
2807 * guile-snarf.awk.in: Tweak to work with Sun/HP awk, removed some
2808 dead code. Patch from Michael Livshin.
2809
2810 * guile-doc-snarf.in: Tweak to work with Sun/HP sh. Patch from
2811 Michael Livshin.
2812
2813 2000-02-09 Gary Houston <ghouston@arglist.com>
2814
2815 * init.c (scm_init_standard_ports): when stdout is a tty, make the
2816 current-output-port unbuffered by default. this is less confusing
2817 for interactive use. it was line-buffered because of a
2818 performance problem with unbuffered ports, but I think it will be
2819 OK now.
2820
2821 2000-02-08 Gary Houston <ghouston@arglist.com>
2822
2823 * __scm.h: don't define long_long or ulong_long if HAVE_LONG_LONGS
2824 is not defined.
2825
2826 * stime.c (scm_localtime, scm_mktime): if neither HAVE_TM_ZONE nor
2827 HAVE_TZNAME are defined, use an empty string instead of giving two
2828 spurious compile-time errors.
2829
2830 Tue Feb 8 13:57:46 2000 Greg J. Badros <gjb@cs.washington.edu>
2831
2832 * ports.c: Doc patches from Richard Kim. Pasted from MIT Scheme.
2833 Thanks Richard!
2834
2835 Mon Feb 7 09:07:31 2000 Greg J. Badros <gjb@cs.washington.edu>
2836
2837 * macros.c: Doc patches from Richard Kim. Pasted from scm.texi.
2838
2839 Sun Feb 6 20:26:21 2000 Greg J. Badros <gjb@cs.washington.edu>
2840
2841 * pairs.c: Doc patches from Richard Kim. Pasted from MIT Scheme
2842 (which is GNU GPL'd).
2843
2844 2000-01-31 Gary Houston <ghouston@arglist.com>
2845
2846 * strings.h: don't use SCM_P. don't include <string.h>.
2847 * error.c, gh_data.c, ports.c, script.c, strop.c: include <string.h>.
2848
2849 * strings.c (scm_string_ref): make the 2nd argument compulsory.
2850 previously it defaulted to zero for no good reason that I can see.
2851 use a local variable for SCM_INUM (k). replace
2852 SCM_VALIDATE_INUM_DEF with SCM_VALIDATE_INUM_COPY.
2853
2854 (scm_makfromstr): cosmetic changes.
2855
2856 (scm_string): Accept only chars in the list, not strings, for
2857 conformance to R5RS (particularly for list->string, which is
2858 supposed to be the inverse of string->list.) remove
2859 SCM_DEFER_INTS/SCM_ALLOW_INTS, which is unnecessary since
2860 scm_makstr handles the cell allocation. when reporting wrong-type
2861 arg, don't report the position as 1.
2862
2863 * posix.c (scm_init_posix): intern PIPE_BUF if it's defined.
2864
2865 2000-01-29 Gary Houston <ghouston@arglist.com>
2866
2867 * posix.c (scm_pipe): rewrote the docstring.
2868
2869 * filesys.c (scm_select, retrieve_select_type, get_element,
2870 fill_select_type, set_element): modified so that Scheme
2871 "select" tests port buffers for the ability to provide input
2872 or accept output. Previously only the underlying file descriptors
2873 were checked. Rewrote the docstring.
2874
2875 Thu Jan 27 10:14:25 2000 Greg J. Badros <gjb@cs.washington.edu>
2876
2877 * vectors.c, symbols.c, strorder.c: Documentation cut and pasted
2878 from Gregg Reynolds. Thanks Gregg!
2879
2880 Thu Jan 27 09:59:38 2000 Greg J. Badros <gjb@cs.washington.edu>
2881
2882 * strop.c (scm_i_index): Obfuscated commented-out SCM_DEFINE by
2883 adding "x" prefix to the line so that guile-func-name-check
2884 doesn't complain unnecessarily.
2885
2886 Wed Jan 26 17:33:52 2000 Greg J. Badros <gjb@cs.washington.edu>
2887
2888 * throw.c: Factor out an #ifdef/#else/#endif choice more finely
2889 for maintainability.
2890
2891 * strop.c: Documentation added by Gregg A. Reynolds. Pasted in
2892 from qdocs, RnRs.
2893
2894 Wed Jan 26 10:02:11 2000 Greg J. Badros <gjb@cs.washington.edu>
2895
2896 * tag.c: Added doc for `tag', but mark as deprecated since Mikael
2897 suggests removing tag.c altogether (and using a new `class-of'
2898 instead).
2899
2900 * strings.c: Added documentation from Gregg A. Reynolds. Edited
2901 a bit by me to use FOO instead of @var{foo} and to have the
2902 summary come before preconditions on input. Also dropped trailing
2903 (rnrs) note.
2904
2905 * gsubr.c: Do not use SCM_DEFINE for `gsubr-apply'. Register the
2906 function with scm_make_subr_opt w/ last arg of 0 so it is not
2907 visible at the Scheme level. Mikael says that this is the right
2908 thing because the first arg to the proc is the guts of a compiled
2909 closure and shouldn't be exposed to the Scheme level.
2910
2911 Tue Jan 25 17:15:47 2000 Greg J. Badros <gjb@cs.washington.edu>
2912
2913 * sort.c: typo in comment fixed.
2914
2915 * keywords.c: Added documentation.
2916
2917 * guardians.c: Added documentation (could be better).
2918
2919 * gc.c: Added docs for gc-set-debug-check-freelist.
2920
2921 * eq.c: Added docs for eq?, eqv? equal? abridged from R4RS.
2922
2923 * boolean.c: Added docs for `not', `boolean?' (by hand).
2924
2925 Tue Jan 25 13:28:56 2000 Greg J. Badros <gjb@cs.washington.edu>
2926
2927 * random.c: Added documentation, from SLIB page:
2928 http://angela.ctrl-c.liu.se/~calle/scheme/slib_toc.html
2929
2930 Mon Jan 24 17:50:20 2000 Greg J. Badros <gjb@cs.washington.edu>
2931
2932 * variable.c, version.c: Added documentation, written by hand
2933 since I could not find anything already written that was
2934 relevant.
2935
2936 2000-01-23 Gary Houston <ghouston@arglist.com>
2937
2938 * filesys.c (scm_chown): omit port/fdes support if HAVE_FCHOWN is
2939 not defined (thanks to Richard Y. Kim).
2940
2941 Thu Jan 20 13:00:38 2000 Greg J. Badros <gjb@cs.washington.edu>
2942
2943 * Makefile.in: Removed, this is auto-generated.
2944
2945 Thu Jan 20 11:33:47 2000 Dirk Hermann <dirk@ida.ing.tu-bs.de> --applied 01/20/00 gjb
2946
2947 * list.c: Put some variable initialization code at the point of
2948 declaration; Added a comment for list*; Formatting changes.
2949
2950 * load.c: use SCM_NNULLP to make sure the end of a list is not
2951 reached yet.
2952
2953 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2954
2955 * backtrace.c (scm_display_error_message): Bugfix: Don't use
2956 result of scm_list_p as C boolean.
2957 (scm_display_error_message, scm_set_print_params_x): Use new
2958 validation macros. (Thanks to Dirk Herrmann.)
2959
2960 * net_db.c (scm_resolv_error): Cast result from hstrerror.
2961
2962 * strports.c (st_end_input): Inserted parenthesis to get operator
2963 grouping correct.
2964
2965 * list.h (scm_init_list): Removed SCM_P around prototypes.
2966
2967 * fports.c, list.c, numbers.c, ports.c, stime.c, symbols.c,
2968 filesys.c, posix.c: Converted docstrings to ANSI C format and
2969 escaped " occurring inside string literals.
2970
2971 Tue Jan 18 13:21:08 2000 Mikael Djurfeldt <mdj@r11n07-s.pdc.kth.se>
2972
2973 * posix.c (scm_mknod): Escape " occuring inside docstring.
2974
2975 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2976
2977 * alist.c, chars.c, debug.c, dynl.c, dynwind.c, error.c, eval.c,
2978 evalext.c, filesys.c, gc.c, hash.c, hashtab.c, ioext.c,
2979 keywords.c, list.c, load.c, macros.c, net_db.c, numbers.c,
2980 objprop.c, ports.c, posix.c, print.c, procprop.c, procs.c,
2981 ramap.c, regex-posix.c, root.c, scmsigs.c, simpos.c, socket.c,
2982 stacks.c, stime.c, strings.c, strop.c, strports.c, struct.c,
2983 symbols.c, throw.c, unif.c, vectors.c, version.c, vports.c,
2984 weaks.c: Converted docstrings to ANSI C format.
2985
2986 * filesys.c (scm_chmod), simpos.c (scm_system), version
2987 (scm_version), vports (scm_make_soft_port): Escape " occuring
2988 inside docstring.
2989
2990 Mon Jan 17 11:41:22 2000 Greg J. Badros <gjb@cs.washington.edu>
2991
2992 * scm_validate.h: Added SCM_VALIDATE_ULONG_COPY,
2993 SCM_VALIDATE_LONG_COPY
2994
2995 * numbers.c: Use SCM_VALIDATE_ULONG_COPY, instead of
2996 SCM_VALIDATE_INUM_COPY to let bigger numbers be used. Rename a
2997 couple of formal arguments (and fix their uses) to make arguments
2998 match the documentation.
2999
3000 2000-01-14 <mstachow@alum.mit.edu>
3001
3002 * Makefile.am: Augment path when running guile-doc-snarf so
3003 guile-func-name-check is found.
3004
3005 Fri Jan 14 09:34:55 2000 Greg J. Badros <gjb@cs.washington.edu>
3006
3007 * scm_validate.h (SCM_NUM2LONG_DEF): Fix this macro to just use
3008 def, not SCM_MAKINUM(def); thanks Janis Bzerins!
3009
3010 Wed Jan 12 00:06:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3011
3012 * net_db.c (s_scm_inet_makeaddr): Use SCM_NUM2ULONG since that's
3013 the way guile-1.3.4 worked, but #if 0 out the version using
3014 SCM_VALIDATE_INUM_COPY for stricter testing.
3015
3016 Tue Jan 11 18:24:18 2000 Greg J. Badros <gjb@cs.washington.edu>
3017
3018 * guile-doc-snarf.in: Use new $fullfilename for running
3019 guile-func-name-check, and put "$fullfilename" and "$filename" in
3020 quotes at uses to make sure re-splitting on whitespace does not
3021 occur (so filenames w/ embedded whitespace would work okay, though
3022 I sure hope we never have to deal with that! :-) ). Thanks to
3023 Mikael for pointing out the source_dir != build_dir was broken.
3024
3025 Tue Jan 11 17:42:40 2000 Greg J. Badros <gjb@cs.washington.edu>
3026
3027 * scm_validate.h: Added SCM_NUM2LONG_DEF macro. Make
3028 SCM_OUT_OF_RANGE use SCM_MAKINUM, not scm_long2num. Added
3029 SCM_COERCE_ROSTRING macro. Added SCM_VALIDATE_NONEMPTYLIST
3030 macro. Fix SCM_VALIDATE_STRINGORSUBSTR macro to not use SLOPPY
3031 variants.
3032
3033 * ports.c (scm_port_closed_p): Validate that the arg is a PORT,
3034 then return whether it's an open port (was validating that it was
3035 an open port -- this was a bug I introduced back in December, but
3036 my careful reading of diffs caught it).
3037
3038 * numbers.c: Recombine the two conditional-compilation paths for
3039 all the log* primitives -- they were split based on #ifndef
3040 scm_long2num; factored out a SCM_LOGOP_RETURN macro, and fixed
3041 some bugs and inconsistencies in the two sets of implementations.
3042 (scm_lognot) Fixed *atrocious* re-use of a SCM as an integer!
3043
3044 * ioext.c: Use SCM_ASSERT_RANGE in a couple places, and
3045 SCM_VALIDATE_INUM_COPY once where it should've been used.
3046
3047 * fluids.c (scm_internal_with_fluids): Use
3048 SCM_VALIDATE_LIST_COPYLEN.
3049
3050 * filesys.c: Use SCM_NUM2LONG instead of SCM_VALIDATE_INUM_COPY;
3051 this is questionable as it relaxes type safety, but other changes
3052 were useful and all SCM_NUM2LONG's should probably be
3053 revisited. Use SCM_OUT_OF_RANGE, SCM_WRONG_TYPE_ARG.
3054
3055 * evalext.c: line-break change on 1 line.
3056
3057 * eval.c (nconc2last): Takes a non-empty list as its first
3058 argument, not just a list.
3059
3060 * dynl.c: Use new SCM_COERCE_ROSTRING macro.
3061
3062 Tue Jan 11 15:44:23 2000 Greg J. Badros <gjb@cs.washington.edu>
3063
3064 * dynl.c, feature.c, filesys.c, fports.c, list.c, load.c,
3065 net_db.c, sort.c, stacks.c, unif.c: Use SCM_WTA, SCM_MISC_ERROR
3066 where possible.
3067
3068 * symbols.c (scm_sysintern0): Fixed the function name in a
3069 scm_misc_error invocation.
3070
3071 * print.c (scm_simple_format): Do not need SCM_COERCE_SUBSTR, and
3072 use scm_return_first to ward off latent GC bug that Mikael caught.
3073
3074 * async.c: Use SCM_VALIDATE_ASYNC_COPY one place where it wasn't
3075 used before but should've been.
3076
3077 2000-01-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3078
3079 * snarf.h (SCM_PROC1): Replaced SCM (*) (...) with
3080 SCM_FUNC_CAST_ARBITRARY_ARGS.
3081
3082 Tue Jan 11 13:44:07 2000 Greg J. Badros <gjb@cs.washington.edu>
3083
3084 * guile-func-name-check.in: Added this script to statically check
3085 #define FUNC_NAME, #undef FUNC_NAME in the source.
3086
3087 * sort.c, posix.c: Fix #undef FUNC_NAME lines to not have trailing
3088 redundant comment, semicolon; caught by new guile-func-name-check
3089 script.
3090
3091 * debug.c: Fix mistaken #define FUNC_NAME for scm_make_iloc.
3092 Caught by new guile-func-name-check-script.
3093
3094 * Makefile.am: Added guile-func-name-check to bin_SCRIPTS
3095
3096 * ramap.c: Fix #if 0'd out code to be syntactically acceptable to
3097 guile-func-name-check.
3098
3099 * guile-doc-snarf.in: Run guile-func-name-check on the file before
3100 doing the snarf.
3101
3102 Tue Jan 11 11:31:10 2000 Greg J. Badros <gjb@cs.washington.edu>
3103
3104 * fports.c, ports.c, ports.h, strports.c, vports.c: Make write
3105 port function take const void*, not void*.
3106
3107 Tue Jan 11 11:18:07 2000 Greg J. Badros <gjb@cs.washington.edu>
3108
3109 * scm_validate.h, chars.c, ports.c, print.c, read.c, strings.c,
3110 strop.c: Use SCM_VALIDATE_ICHR, SCM_VALIDATE_ICHR_COPY instead of
3111 SCM_VALIDATE_CHAR, SCM_VALIDATE_CHAR_COPY. Change made for
3112 consistency with the other macros dealing with immediate
3113 characters. (Similar to INT -> INUM change a week or so ago).
3114
3115 Tue Jan 11 10:41:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3116
3117 * dynl.c, error.c, eval.c, feature.c, filesys.c, fports.c, list.c, load.c,
3118 net_db.c, read.c, socket.c: Update error messages to use ~A for
3119 %s, ~S for %S to work with new `simple-format' format and be
3120 standardized better.
3121
3122 * print.h, print.c (scm_simple_format): Added `simple-format'
3123 primitive. It's the old scm_display_error, with ARGS now a rest
3124 parameter, and the destination first instead of last (and a couple
3125 new capabilities inspired by `format' -- #t as destination means
3126 current-output-port, #f means return the formatted text as a
3127 string.
3128
3129 * gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
3130
3131 * backtrace.c (scm_display_error_message): Rewrote to use
3132 scm_simple_format() procedure.
3133
3134 * __scm.h: Added commented-out #define of GUILE_DEBUG_FREELIST
3135
3136 2000-01-09 Marius Vollmer <mvo@zagadka.ping.de>
3137
3138 Finally applied the libltdl patch from Thomas Tanner, with slight
3139 modifications.
3140
3141 * DYNAMIC-LINKING: Removed because it is obsolete.
3142 * dynl.c: Use ANSI prototypes.
3143 (sysdep_dynl_link): Use lt_dlopenext instead of lt_dlopen.
3144 * scmconfig.h.in: Do not change, as it is automatically generated.
3145
3146 1999-07-25 Thomas Tanner <tanner@ffii.org>
3147
3148 * dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c: deleted
3149 (obsolete)
3150 * Makefile.am: likewise, add INCLTDL (libltdl headers) to
3151 INCLUDES, set dlpreopened files in LDFLAGS, link libguile
3152 against libltdl
3153 * dynl.c: use libltdl if DYNAMIC_LINKING is enabled,
3154 * guile.c: register preloaded modules
3155 * scmconfig.h.in: remove obsolete symbols
3156
3157 2000-01-09 Gary Houston <ghouston@arglist.com>
3158
3159 * These changes should make it unnecessary to call tzset from
3160 Scheme after modifying the TZ environment variable, even if the
3161 system date facilities cache the value.
3162 * stime.c (setzone, scm_localtime): added comments.
3163 (tzset): don't define a noop tzset macro if HAVE_TZSET not defined.
3164 (setzone): don't call tzset.
3165 (restorezone): call tzset only if HAVE_TZSET is defined.
3166 (scm_tzset): don't define if HAVE_TZSET not defined. Change the
3167 doc string to indicate that this procedure isn't likely to do
3168 anything useful.
3169 (scm_localtime, scm_strftime, scm_mktime): call tzset if
3170 LOCALTIME_CACHE is defined.
3171
3172 2000-01-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3173
3174 * posix.c (scm_sync): Return SCM_UNSPECIFIED.
3175
3176 2000-01-09 Gary Houston <ghouston@arglist.com>
3177
3178 * eval.c: define scm_unbound_variable_key ('unbound-variable).
3179 scm_lookupcar1: throw an error with key 'unbound-variable instead
3180 of 'misc-error when an unbound variable is encountered.
3181
3182 * filesys.c (scm_mkdir, scm_rmdir, scm_getcwd, scm_select,
3183 scm_symlink, scm_readlink, scm_lstat),
3184 posix.c (scm_setpgid, scm_setsid, scm_ctermid, scm_tcgetpgrp,
3185 scm_tcsetpgrp, scm_uname, scm_setlocale, scm_mknod, scm_nice,
3186 scm_sync),
3187 simpos.c (scm_system),
3188 stime.c (scm_times, scm_strptime):
3189 move the HAVE_XXX feature tests out of the procedure bodies.
3190 don't use SCM_SYSMISSING.
3191 scm_validate.h (SCM_SYSMISSING): removed.
3192 error.h, error.c (scm_sysmissing): comment that this is deprecated.
3193 see ChangeLog entry for 1999-12-28.
3194
3195 Sat Jan 8 19:52:04 2000 Greg J. Badros <gjb@cs.washington.edu>
3196
3197 * scm_validate.h (SCM_VALIDATE_BOOL_COPY): Fix typo.
3198
3199 Sat Jan 8 17:06:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3200
3201 * backtrace.c: Fix spelling typo in a comment.
3202
3203 * snarf.h: Use new SCM_DOCS macro to encapsulate the non SCM_INIT
3204 text. Reformatted some of the expansions.
3205
3206 Fri Jan 7 15:50:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3207
3208 * scm_validate.h (SCM_OUT_OF_RANGE): Use scm_out_of_range_pos to
3209 report the position of the argument.
3210
3211 * error.h, error.c (scm_out_of_range_pos): Added this function to
3212 take extra "pos" argument, the position number of the errant
3213 argument.
3214
3215 * debug.c: Use SCM_OUT_OF_RANGE instead of scm_out_of_range.
3216
3217 * snarf.h: Use SCM_HERE and SCM_INIT as names, not SCM_NOTSNARF
3218 and SCM_SNARFING. Also put the %%% in the SCM_INIT since Mikael
3219 prefers that and I'm reasonably indifferent.
3220
3221 Fri Jan 7 15:03:32 2000 Greg J. Badros <gjb@cs.washington.edu>
3222
3223 * snarf.h: Factor out differences between C++ and non-C++ into
3224 SCM_FUNC_CAST_ARBITRARY_ARGS macro. Modify all the snarf macro
3225 definitions to use SCM_NOTSNARF and SCM_SNARFING macros (like
3226 Mikael's macros, below, but changed names and SCM_SNARFING no
3227 longer expands to include %%% -- that must appear in the argument
3228 so that the token appears at the call-site as a reminder).
3229
3230 2000-01-07 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3231
3232 * snarf.h (SCM_INSITU, SCM_INIT): New snarf macros for use in user
3233 snarf macro definitions.
3234
3235 2000-01-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3236
3237 * chars.c (scm_integer_to_char): Use Greg's nice
3238 SCM_VALIDATE_INUM_RANGE macro for argument checking for closer
3239 adherence to R5RS.
3240
3241 Thu Jan 6 11:48:49 2000 Greg J. Badros <gjb@cs.washington.edu>
3242
3243 * *.c, snarf.h: Replace GUILE_PROC1 with SCM_DEFINE1 throughout.
3244
3245 Thu Jan 6 11:22:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3246
3247 * Makefile.am (ETAGS_ARGS): Switch to SCM_DEFINE, SCM_DEFINE1
3248 instead of GUILE_PROC.
3249
3250 Thu Jan 6 11:21:49 2000 Greg J. Badros <gjb@cs.washington.edu>
3251
3252 * alist.c: Do not report mismatch errors on some uses of `tmp' (do
3253 this by using SCM_ARG2 instead of `2' in the SCM_VALIDATE_CONS
3254 macro call.
3255
3256 Thu Jan 6 09:54:33 2000 Dirk Herrmann <dirk@ida.ing.tu-bs.de> --gjb applied
3257
3258 * scm_validate.h: Remove some redundant NIMP tests.
3259
3260 * alist.c: minimize scope of the tmp variables, and initialize
3261 them when declared. The strange SCM_NIMP tests are replaced by
3262 SCM_CONSP tests that more closely reflect the intended semantics.
3263 However, we don't get a performance penalty here, because the
3264 SCM_CONSP test was performed by the ALISTCELL test anyway. * The
3265 extremely ugly use of ASRTGO macros was removed: The calls to
3266 ASRTGO were not encapsulated by "#ifndef SCM_RECKLESS", but got a
3267 label parameter that only exists when SCM_RECKLESS is not defined.
3268 This works, because ASRTGO itself is defined in a way that it only
3269 makes use of the label parameter if SCM_RECKLESS is not defined
3270 (shudder!). Does guile make at all use of the possibility to
3271 define SCM_RECKLESS? * Codesize is likely to be reduced, since
3272 instead of two calls to SCM_ASSERT performed by the ALISTCELL test
3273 we now only get one test.
3274
3275 * list.c: Use SCM_NNULLP, not SCM_NIMP as appropriate. Also use
3276 SCM_NULLP instead of SCM_IMP. Drop use of "register" keyword on
3277 some variables in `list?'. Fix `reverse' and `reverse!'
3278 primitives to handle improper lists better.
3279
3280 Wed Jan 5 11:24:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3281
3282 * *.[ch]: Whitespace changes -- added space after SCM_VALIDATE_*
3283 macros and SCM_DEFINE macros to match GNU coding standards.
3284
3285 Wed Jan 5 11:04:24 2000 Greg J. Badros <gjb@cs.washington.edu>
3286
3287 * *.[ch]: Replace GUILE_PROC w/ SCM_DEFINE.
3288
3289 Wed Jan 5 10:59:06 2000 Greg J. Badros <gjb@cs.washington.edu>
3290
3291 * *.[ch]: Replace SCM_VALIDATE_INT w/ SCM_VALIDATE_INUM for
3292 better consistency with the names of other SCM_VALIDATE_ macros
3293 and better conformance to guile naming policy.
3294
3295 Wed Jan 5 10:50:39 2000 Greg J. Badros <gjb@cs.washington.edu>
3296
3297 * ports.c (s_scm_close_all_ports_except): Use SCM_ARG1 in a
3298 SCM_VALIDATE instead of 1 to avoid a check on the argument (since
3299 it's not the actual name of the formal).
3300
3301 * guile-snarf.awk.in: Do argument/number mismatch checking and
3302 print warnings in an Emacs compile-mode parseable format.
3303
3304 * struct.c: Use SCM_ASSERT_RANGE instead of SCM_ASSERT w/
3305 SCM_OUTOFRANGE as 3rd argument.
3306
3307 * random.c: Fix argument/number mismatch (that I introduced :-( ).
3308
3309 * __scm.h: Do not #define SCM_ARG* when snarfing;
3310 lets us distinguish between 1 and SCM_ARG1 when snarfing as only
3311 the former (using the number) requires the argument to match the
3312 formal in the current argument snarfing check.
3313
3314 * snarf.h: Give new definition of SCM_ASSERT when in
3315 snarfing mode to output a lexically-identifiable sequence that the
3316 guile-snarf.awk script uses to verify argument/position matching.
3317
3318 * ramap.c: Remove extraneous #undef FUNC_NAME.
3319
3320 Wed Jan 5 08:36:38 2000 Greg J. Badros <gjb@cs.washington.edu>
3321
3322 * guile-doc-snarf.awk.in: Removed -- guile-snarf.awk.in is the
3323 current version of the same functionality; it writes the .x output
3324 to stdout instead of directly into the file.
3325
3326 Wed Jan 5 08:15:04 2000 Greg J. Badros <gjb@cs.washington.edu>
3327
3328 * unif.c, symbols.c, strings.c, stacks.c, random.c, print.c,
3329 posix.c: Eliminated a bunch of SCM_NIMP(..)s that are now
3330 redundant with the safer macros. Patch from Dirk Hermann applied
3331 by hand. Thanks Dirk!
3332
3333 * scm_validate.h: Added SCM_VALIDATE_VECTOR_OR_DVECTOR for some
3334 uses in random.c.
3335
3336 * ramap.c: whitespace change.
3337
3338 Tue Jan 4 14:21:35 2000 Greg J. Badros <gjb@cs.washington.edu>
3339
3340 * options.c, objects.c, keywords.c, gc.c: Some redundant SCM_NIMP
3341 removals from Dirk Hermann.
3342
3343 * alist.c: Rename formals to match the parameter names in the
3344 documentation, updates to documentation. Thanks Dirk Hermann!
3345
3346 2000-01-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3347
3348 * eval.c (SCM_CEVAL): Reverse order of
3349 scm_stack_checking_enabled_p and SCM_STACK_OVERFLOW_P
3350 (Thanks to Brad Knotwell.)
3351
3352 Mon Jan 3 08:30:02 2000 Greg Harvey <Greg.Harvey@thezone.net> (applied --01/03/00 gjb)
3353
3354 * gc.c (scm_debug_newcell): Added SCM_SETCAR of the newly
3355 allocated cell.
3356
3357 * pairs.h: Added a comment about the need for the SCM_SETCAR in
3358 SCM_NEWCELL macro.
3359
3360 Mon Jan 3 08:25:19 2000 Greg J. Badros <gjb@cs.washington.edu>
3361
3362 * dynl-vms.c, debug.c, coop-threads.c, backtrace.c, eval.c: More
3363 SCM_NIMP tests that were redundant are now eliminated. Patches
3364 from Dirk Hermann applied by hand.
3365
3366 The ChangeLog continues in the file: "ChangeLog-1996-1999"
