3 this changes the Guile GC to use cards (aka "chunklets").
4 (most of the ideas and some of the code are by Greg Harvey, though
5 the code is probably unrecognizable now. the original chunklet
6 proposal, way back, is by Dale Jordan).
8 * tags.h: (SCM_GCTYPE16, SCM_GCCDR, SCM_GC[8]MARKP,
9 SCM_SETGC[8]MARK, SCM_CLRGC[8]MARK): moved from here into gc.h.
10 some (most) of these are probably going to be deprecated.
12 * gc.h (SCM_MARKEDP): simplified, there are no different mark bit
14 (SCM_GC_CARD_*, SCM_C_BVEC_*): lots of new macros to deal with
15 cards and bvecs (bit-vectors).
17 * gc.c: (scm_default_init_heap_size_*): defined to take cards into
18 account, but keeping more or less the same values as previously.
19 added some simple helper macros.
20 (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK): defined to take cards
22 (BVEC_*, scm_mark_space_t, current_mark_space, mark_space_ptr,
23 current_mark_space_offset, mark_space_head, get_bvec,
24 clear_mark_space): new functions and supporting variables, types
25 and macros that implement mark space management.
26 (scm_igc): clear the mark space (all of it) before beginning the
28 (scm_gc_mark): changed the tests for rogue cells, much simplified
29 throughout (no different mark bit locations to worry about now).
30 (scm_mark_locations): don't consider card header cells.
32 (scm_gc_sweep): simplified.
33 (init_heap_seg): changed to take cards into account.
35 2000-08-16 Michael Livshin <mlivshin@bigfoot.com>
37 * stime.c (scm_c_get_internal_run_time): new function, same as
38 scm_get_internal_run_time but returns a long. it's used by the GC
39 for timekeeping, since with scm_get_internal_run_time there is a
40 (extremely theoretical) possibility of consing.
41 (scm_get_internal_run_time): redefined in terms of
42 scm_c_get_internal_run_time.
44 * stime.h: added prototype for scm_c_get_internal_run_time.
46 * gc.c (scm_gc_stats): add more obscure stats, such as: mark time,
47 sweep time, total marked cells, total swept cells, and number of
49 (gc_start_stats): renamed from scm_gc_start, made static, taught
50 to init the new stats.
51 (gc_end_stats): renamed from scm_gc_end, made static, taught to
52 calculate the new stats.
53 (scm_igc): don't call gc_start_stats unless we are sure that we
54 are indeed going to collect. also, added some timekeeping between
55 the mark and sweep phases.
56 (scm_gc_sweep): count number of cells we sweep as we go.
58 * gc.h: removed prototypes for scm_gc_{start,end}.
60 2000-08-13 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
62 * alist.c (scm_assq, scm_assv, scm_assoc): Report argument type
63 error for the alist rather than the sublist where the type
64 mismatch is discovered.

95 reference manual doc on keywords.
97 * error.c (scm_error_scm): Fix texinfo syntax error in
98 docstring. (@code(~S) should be @code{~S}.)
100 * dynl.c: Remove surplus newlines from end of docstrings.
102 2000-08-11 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
104 * eval.c (scm_eval): Backward incompatible change: Now takes an
105 environment specifier as second arg. `eval' hereby becomes R5RS
107 (scm_i_eval_x, scm_i_eval): New functions (replace
109 (scm_eval2, scm_eval_3): Deprecated.
110 (scm_top_level_lookup_closure_var): Deprecated.

133 scm_interaction_environment ().
135 * script.c (scm_shell): Pass scm_the_root_module () as second arg
138 * load.c (load): Use `scm_selected_module' to compute second arg
139 to new scm_i_eval_x; Don't call it if module system hasn't booted.
140 (scm_read_and_eval_x): Deprecated.
141 #include "modules.h".
143 * debug.c (scm_local_eval): Use scm_i_eval and scm_i_eval_x.

146 * strports.c: #include "modules.h".
148 * print.c (scm_simple_format): Be case-insensitive for ~A and ~S
151 2000-08-09 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
153 The following changes are intended to ensure that struct instances
154 are freed before their vtables. It's optimized for the most
155 common case, which is freeing of struct instances.
157 * gc.c (scm_gc_mark, scm_gc_sweep): Remove vcell = 1 magic.
158 (scm_structs_to_free): New variable.
159 (scm_gc_sweep): Hook up structs to free on the scm_structs_to_free
162 * struct.h (SCM_STRUCT_GC_CHAIN, SCM_SET_STRUCT_GC_CHAIN): New
164 (scm_structs_to_free, scm_struct_prehistory): Declare.
166 * struct.c (scm_make_struct, scm_make_vtable_vtable): Structs
167 handles are now double cells; Initialize SCM_STRUCT_GC_CHAIN to
169 (scm_struct_gc_init, scm_free_structs): New GC C hooks.
170 (scm_struct_prehistory): Install them.
172 * init.c (scm_boot_guile_1): Call scm_struct_prehistory.
174 2000-08-06 Marius Vollmer <mvo@zagadka.ping.de>
176 * read.c (scm_flush_ws): Include filename in error message when it
179 2000-08-05 Marius Vollmer <mvo@zagadka.ping.de>
181 * iselect.c: Include <unistd.h>. Thanks to Bertrand Petit!
183 2000-08-02 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
185 * struct.c (scm_make_struct_layout, scm_make_struct,
186 scm_make_vtable_vtable): Updated documentation.
188 * print.c (scm_simple_format): Bugfix: Coerce port before using
191 2000-07-31 Gary Houston <ghouston@arglist.com>
193 * net_db.c: declare h_errno only if HAVE_H_ERRNO is not defined
194 (thanks to Richard Kim for the bug report).
196 2000-07-30 Marius Vollmer <mvo@zagadka.ping.de>
198 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
199 scm_assoc_remove_x): Use scm_delq1_x instead of scm_delq_x, since
200 using the latter is pointless.
202 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
204 * gc.c (scm_gc_sweep): Renamed local variable from 'free' to
205 'free_struct_data' to avoid confusion with stdlib's 'free'.
207 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
209 * vectors.c (scm_make_vector): Fix the initialization order of
210 the vector such that the type cell is initialized last.
212 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
214 * struct.[ch] (scm_struct_init): Made static. Fixed not to rely
215 on the struct cell to be fully initialized.
217 * struct.c (scm_make_struct, scm_make_vtable_vtable): Fix the
218 initialization order of the struct such that the type cell is
221 2000-07-25 Marius Vollmer <mvo@zagadka.ping.de>
223 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
224 scm_assoc_remove_x): Remove only the first cell with a matching
227 2000-07-24 Marius Vollmer <mvo@zagadka.ping.de>
229 * stime.c (scm_strftime): Recognize a return value of zero from
230 strftime as buffer overflow and take care to detect a valid zero
231 length result regardless. Thanks to David Barts!
233 2000-07-23 Marius Vollmer <mvo@zagadka.ping.de>
235 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
236 scm_assoc_remove_x): Remove all cells whose key is eq, eqv, or
237 equal (respectively) to the argument key, not all cells that are
238 eq, eqv, or equal to the first cell with the argument key. Thanks
241 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
243 * gc.h (SCM_FREE_CELL_CDR, SCM_SET_FREE_CELL_CDR), hooks.c
244 (make_hook), modules.c (OBARRAY, USES, BINDER): Pack and unpack
245 SCM values appropriately.
247 * modules.c (scm_standard_eval_closure): Don't pass an inum to
248 scm_makcclo, but rather a long value.
250 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
252 read.c (scm_lreadrecparen), srcprop.c (scm_set_source_property_x):
253 SCM_SETCDR and SCM_WHASHSET macros don't deliver a return value.
254 Thanks to Han-Wen Nienhuys for the bug report.
256 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
258 * root.[ch] (scm_call_catching_errors): Deprecated.
260 * root.c (scm_init_root): Initialize the root smob type using the
261 standard initialization functions.
263 2000-07-17 Marius Vollmer <mvo@zagadka.ping.de>
265 * eval.c (unmemocopy): Don't rely on V being a list of at least
266 one element. Thanks to Bill Schottstaedt!
268 2000-07-15 Michael Livshin <mlivshin@bigfoot.com>
270 * gc.c (scm_done_free): new.
271 expanded comments about scm_done_malloc.
273 * gc.h: added prototype for scm_done_free
275 2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
277 * gc.h (scm_take_stdin): Removed.
279 * gc.h (SCM_VALIDATE_CELL): Delegate cell checks to function
280 scm_assert_cell_valid to allow extensions to the checking
281 functionality without need to recompile everything.
283 * gc.[ch] (scm_assert_cell_valid, scm_set_debug_cell_accesses_x):
284 Added as conditionally compiled functions for the case that
285 SCM_DEBUG_CELL_ACCESSES is enabled.
287 * gc.c (debug_cells_p): Added to indicate whether compile-time
288 included cell access debugging is run-time enabled.
290 * gc.[ch] (scm_gc_running_p): Added to indicate that scm_igc is
291 being executed. Intended to be used instead of scm_gc_heap_lock
294 * error.c (scm_error), gdbint.c (SCM_GC_P): Use scm_gc_running_p
295 instead of scm_gc_heap_lock.
297 * gc.c (scm_igc): Set scm_gc_running_p to true while running.
299 * gc.c (scm_mark_locations): Don't mark free cells.
301 * weaks.c (scm_scan_weak_vectors): Use SCM_FREE_CELL_P instead of
304 2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
306 * gc.c (scm_mark_locations): Minimized some variable scopes and
307 simplified the code a bit.
309 2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
311 * gc.h (SCM_SET_FREE_CELL_TYPE, SCM_SET_FREE_CELL_CDR,
312 SCM_FREE_CELL_P, SCM_FREE_CELL_CDR): Added since free cells
313 should not be accessed via SCM_C[AD]R. Further, using dedicated
314 macros to access free cells allows all other cell accessing macros
315 to treat acesses to free cells as errors, thus enabling better
316 error checks for cell accesses. SCM_FREE_CELL_P is supposed to
317 replace SCM_FREEP some time.
319 * gc.h (SCM_NEWCELL, SCM_NEWCELL2), gc.c (map_free_list,
320 free_list_length, scm_check_freelist, scm_debug_newcell,
321 scm_debug_newcell2, freelist_length, scm_gc_for_newcell,
322 scm_gc_mark, scm_gc_sweep, init_heap_seg): Only use the dedicated
323 cell accessors when accessing free cells.
325 2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
327 * gc.h (SCM_CELL_WORD, SCM_CELL_OBJECT): Treat the referenced
328 object as const in order to make the compiler warn about code like
329 SCM_CELL_WORD (x, n) = y. Instead, SCM_SET_CELL_WORD (x, n, y)
332 (SCM_CELL_WORD_LOC, SCM_CARLOC, SCM_CDRLOC): Return the address
333 as an address to a non-const object, since these macros are used
334 to allow direct write access to objects.
336 2000-07-07 Dirk Herrmann <D.Herrmann@tu-bs.de>
338 * hashtab.c (scm_hash_fn_create_handle_x): Signal an error if the
339 given hash table has no slots.
341 2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
343 * gc.c (policy_on_error): Added in order to allow alloc_some_heap
344 to react to malloc failures in a context dependent way.
346 (scm_check_freelist): No need to flush streams before abort().
348 (scm_gc_for_newcell): Try to allocate new memory in three phases:
349 grow heap if preferred, if still no memory available collect
350 garbage, if still no memory available grow heap.
352 (heap_segment_table_size): Added to always reflect the actual
353 size of the heap segment table, because scm_n_heap_segs may differ
354 from the heap segment table size.
356 (alloc_some_heap): In case of malloc failure, react according to
357 the new policy_on_error parameter (either return to caller or
358 abort immediately). Further, keep heap_segment_table_size up to
361 (scm_init_storage): Initialize heap_segment_table_size.
363 2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
365 * gh.h: Don't include <stdio.h>. Thanks to Han-Wen Nienhuys for
368 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
370 * __scm.h (SCM_OUTOFRANGE, SCM_NALLOC, SCM_HUP_SIGNAL,
371 SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL, SCM_SEGV_SIGNAL,
372 SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL, SCM_SIG_ORD,
373 SCM_ORD_SIG, SCM_NUM_SIGS): Re-introduce these as deprecated
376 * error.c (scm_wta): Re-introduce dispatching for SCM_OUTOFRANGE
377 and SCM_NALLOC, but as a deprecated feature.
379 2000-06-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
381 * debug.c: Added #include fluids.h.
383 * numbers.c (scm_gr_p, scm_leq_p, scm_geq_p): Turned into
384 primitive generics. (Thanks to Nicolas Neuss.)
386 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
388 * gc.c (alloc_some_heap): Use scm_memory_error to indicate a
389 failed attempt to get additional memory from the system.
391 (scm_gc_for_newcell): Changed the control structure to make the
392 behaviour explicit for the case that gc is not able to free any
395 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
397 * __scm.h (SCM_OUTOFRANGE): Removed.
399 * error.c (scm_wta): Removed sick dispatch code for range
400 errors. (More sick dispatches still to be removed.)
402 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
403 scm_hash_fn_remove_x): Eliminate redundant test for if unsigned
404 value is non-negative. Use scm_out_of_range to signal range
407 * hooks.c (make_hook), unif.c (scm_aind): Use scm_out_of_range to
410 * list.c (scm_list_ref, scm_list_set_x, scm_list_cdr_set_x): Fix
411 error reporting (now uses original input parameter to report wrong
412 type argument errors). Use SCM_OUT_OF_RANGE to report range
413 errors and SCM_WRONG_TYPE_ARG to report type errors.
415 * strings.c (scm_substring): Make range checks for negative
416 values explicit (former behaviour relied on an implicit
417 conversion from signed to unsigned). Don't use SCM_ASSERT for
420 * unif.c (scm_aind, scm_transpose_array, scm_bit_set_star_x,
421 scm_bit_count_star): Use scm_out_of_range to signal range
424 * unif.c (scm_transpose_array, scm_bit_position), vectors.c
425 (scm_vector_ref, scm_vector_set_x, scm_vector_move_left_x,
426 scm_vector_move_right_x): Use SCM_ASSERT_RANGE to check ranges.
428 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
430 * validate.h (SCM_VALIDATE_INUM_MIN_COPY,
431 SCM_VALIDATE_INUM_MIN_DEF_COPY, SCM_VALIDATE_INUM_RANGE_COPY):
432 Perform all range checks based on the input value. The former way
433 of using the value that is assigned to the target variable fails
434 if the assignment to the target variable itself can change the
435 value because of type conversion.
437 (SCM_ASSERT_RANGE): Use scm_out_of_range to signal range errors.
439 2000-06-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
441 * gc.c (scm_gc_for_newcell): Behave gracefully also if scm_igc
442 doesn't yield any new cells. In theory this could happen if all
443 cells allocated with NEWCELL are either in use or conservatively
444 marked and all cluster spine cells are conservatively marked.
447 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
449 * __scm.h (SCM_NALLOC): Removed.
451 * error.c (scm_wta): Removed sick dispatch code for memory
452 errors. (More sick dispatches still to be removed.)
454 * numbers.c (scm_mkbig, scm_adjbig), ports.c (scm_make_port_type),
455 random.c (scm_i_copy_rstate, scm_c_make_rstate), smob.c
456 (scm_make_smob_type), srcprop.c (scm_make_srcprops), vectors.c
457 (scm_vector_set_length_x): Now using scm_memory_error to signal
460 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
462 * __scm.h: Removed some commented code and fixed some comments.
464 (SCM_HUP_SIGNAL, SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL,
465 SCM_SEGV_SIGNAL, SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL,
466 SCM_SIG_ORD, SCM_ORD_SIG, SCM_NUM_SIGS): Removed.
468 * async.c: Removed some commented code.
470 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
472 * gc.c (scm_gc_mark, scm_gc_sweep, scm_must_malloc,
473 scm_must_realloc, scm_must_free, alloc_some_heap): Use the
474 appropriate error signalling function.
476 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
478 * root.h (scm_first_type): Removed.
480 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
482 * gc.c (MIN_GC_YIELD): Removed.
484 2000-06-28 Michael Livshin <mlivshin@bigfoot.com>
486 * gc.c (scm_gc_for_newcell): don't try to do GC if it's blocked,
489 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
491 * async.c (scm_gc_async, scm_gc_vcell, scm_sys_gc_async_thunk):
494 (scm_init_async): Moved initialization for scm_gc_async and
495 scm_gc_vcell to gc.c. Moved initialization of scm_asyncs here
498 * async.h (scm_gc_async): Not globally visible any more.
500 * gc.c (scm_gc_stats): Made callable even from within regions
503 (scm_gc_end): Eliminate the hardcoding of the marking of the
504 scm_gc_async from the gc core.
506 (scm_init_storage): Don't initialize the scm_asyncs list here.
507 This is now done in asyncs.c.
509 (scm_gc_vcell): Moved here from async.c.
511 (gc_async): Renamed from scm_gc_async, moved here from async.c
514 (gc_async_thunk): Renamed from scm_sys_gc_async_thunk and moved
517 (mark_gc_async): New hook function for scm_after_gc_c_hook.
519 (scm_init_gc): Added initialization of scm_gc_vcell and
520 gc_async. Further, add mark_gc_async to scm_after_gc_c_hook.
522 * init.c (scm_boot_guile_1): scm_init_gc requires asyncs to be
525 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
527 * gc.c (scm_igc): Removed commented code that once was intended
528 to unprotect struct types with no instances.
530 * root.h (scm_type_obj_list): Removed.
532 2000-06-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
534 * async.c (scm_init_async): Switch to standard way of smob
537 2000-06-21 Michael Livshin <mlivshin@bigfoot.com>
539 * guile-doc-snarf.in: use cut instead of sed, that's much much
540 faster. also, don't call basename more than needed. and, to gain
541 a couple of microseconds more, don't call cat needlessly. (thanks
544 2000-06-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
546 * guile-snarf.awk.in, guile-snarf.in, snarf.h: Rename SCM__I to
547 SCM_SNARF_INIT_START, SCM__D to SCM_SNARF_DOC_START, SCM__S to
548 SCM_SNARF_DOCSTRING_START and SCM__E to SCM_SNARF_DOCSTRING_END.
550 2000-06-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
552 * eval.c, eval.h (scm_top_level_lookup_closure_var): Added.
553 #include "libguile/fluids.h".
555 * eval.h (SCM_TOP_LEVEL_LOOKUP_CLOSURE): New macro which replaces
556 SCM_CDR (scm_top_level_lookup_closure_var) everywhere.
558 * root.h (scm_top_level_lookup_closure_var,
559 scm_system_transformer): Removed. (It's no sense in having the
560 *variable* be a "fluid".)
562 * root.c (mark_root): Removed marking of
563 s->top_level_lookup_closure_var and s->system_transformer.
565 * modules.c (scm_selected_module): the_module is now a fluid.
567 2000-06-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
569 * gc.h, tags.h: Be kind to compilers which must see hash signs in
570 column 0. (Thanks to Ian Grant.)
572 * numbers.h: Put #ifdef HAVE_LONG_LONGS around declarations using
573 the long_long type. (Thanks to Bernard Urban.)
575 2000-06-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
577 * gc.c, gc.h (scm_default_init_heap_size_1,
578 scm_default_min_yield_1, scm_default_init_heap_size_2,
579 scm_default_min_yield_2, scm_default_max_segment_size): New global
580 variables. Can be customized by the application before booting
581 Guile. (We might want to be able to control these parameters
582 dynamically through the "options interface" in the future, but
583 note that that is additional functionality. Here we're giving
584 default values which the environment variables can override.)
586 * list.c (scm_cons_star): Updated comment.
588 * smob.h: Changed comments for scm_make_smob_type and
589 scm_make_smob_type_mfpe, warning that the latter might be
590 deprecated in a future release.
592 2000-06-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
594 * list.[ch] (scm_cons_star/cons*): Renamed from
597 * list.[ch] (scm_list_star/list*): Provided as a deprecated alias
598 for scm_cons_star/cons*.
600 * gc.c (scm_protect_object): Updated comment.
602 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX): Removed.
604 * tags.h (SCM_UNPACK_CAR, SCM_NDOUBLE_CELLP): Removed.
606 2000-06-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
608 * init.c, init.h (scm_initialized_p): Renamed from `initialized'
611 * gdbint.c (gdb_print): Print warning instead of calling scm_write
612 if Guile isn't yet initialized.
614 * print.c (scm_current_pstate, scm_make_print_state): Simplified
615 tests, using the assumption that Guile has been initialized.
617 Sun Jun 18 14:45:21 2000 Greg J. Badros <gjb@cs.washington.edu>
619 * print.c (s_scm_current_pstate): Do not segfault when the
620 print_state_pool is unitialized in `current-pstate', and better
621 verify its state before altering it in scm_make_print_state().
623 2000-06-18 Michael Livshin <mlivshin@bigfoot.com>
625 * scmsigs.c (s_scm_sigaction): guard the SIGIOT case with an
626 #ifdef -- it's missing on at least one platform. (thanks to
629 2000-06-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
631 * list.c (list*): Added documentation from common-list.scm.
633 2000-06-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
635 * gc.c (scm_unprotect_object): The reference count is guaranteed
636 to be a positive number.
638 2000-06-15 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
640 * eval.c: Updated comment above scm_map.
642 2000-06-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
644 * gc.c (scm_protect_object): Avoid looking up the object handle
646 (scm_unprotect_object): Abort if scm_unprotect_object is called on
647 an unprotected object.
649 2000-06-14 Michael Livshin <mlivshin@bigfoot.com>
651 * gc.c (scm_unprotect_object): fix a nasty typo bug (thanks to
654 2000-06-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
656 * socket.c (scm_getsockopt): Changed type for `optlen' from int to
658 (scm_accept, scm_getsockname, scm_getpeername, scm_recvfrom):
659 Ditto for `tmp_size'.
660 (scm_addr_buffer_size): Changed type from int to size_t.
662 * random.c: #include <string.h>. (Needed by memcpy.)
664 * guile-snarf.awk.in: Replace the dot_doc_file arg with "-",
665 indicating stdin, instead of "" and don't reset ARGC. This is a
666 workaround for `nawk' in AIX 4.3 on RS6000 but, as far as I know,
667 it is correct, and perhaps even better.
669 2000-06-14 Gary Houston <ghouston@arglist.com>
671 * scmsigs.c (scm_init_scmsigs): if HAVE_SIGINTERRUPT is not
672 defined, add SA_RESTART to the sigaction flags correctly
673 (thanks to Dale P. Smith).
675 2000-06-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
677 * strings.c: #include <string.h>. (Thanks to Bill Schottstaedt.)
679 * net_db.c (scm_resolv_error): Only use macro NETDB_INTERNAL if
680 defined. It isn't on sgi irix 5.3. (Thanks to Bill Schottstaedt.)
682 * Makefile.am (.c.doc): Pipe output (the .x contents) to /dev/null.
684 2000-06-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
686 * fports.c (scm_setvbuf): Use `free' instead of `scm_must_free'
687 since read and write buffers are allocated by `malloc'.
689 * Makefile.am: Removed old test code.
691 * gh_test_c.c, gh_test_repl.c: Removed.
693 2000-06-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
695 * iselect.c (SCM_NLONGBITS): Add workaround for the Sun 4.2
698 * inet_aton.c (inet_aton): Cast init value for `cp'.
700 * ramap.c (s_scm_array_fill_x): Cast `ve' properly in case
703 * symbols.c (scm_intern_obarray_soft,
704 scm_sysintern0_no_module_lookup): Cast `name' to unsigned char ptr
705 in calls to scm_strhash.
707 * strports.c (st_resize_port): Substituted SCM_UCHARS for
709 (st_write): Cast argument to strncpy to char ptr.
710 (scm_mkstrport): Substituted SCM_ROUCHARS for SCM_ROCHARS.
711 (scm_strport_to_string): Cast argument to scm_makfromstr to char
714 * ports.c (scm_ungetc): Cast value to unsigned char ptr before
715 storing in putback_buf.
716 (scm_unread_string): Substituted SCM_ROCHARS for SCM_ROUCHARS.
718 * ioext.c (s_scm_read_line): Cast result of call to
719 scm_do_read_line to unsigned char ptr.
721 * gdbint.c (SEND_STRING): Cast argument to char pointer.
723 * fports.c (fport_flush): Declare `ptr' as unsigned char (was
726 * Makefile.am (DOT_DOC_FILES): List doc-files explicitly. (We
727 shouldn't use Make rules which aren't supported by most Make
729 (OMIT_DEPENDENCIES): Defined to "libguile.h ltdl.h". (We don't
730 want these dependencies recorded, since they would get bogus
731 relative paths; libguile.h is only used in gh.h and guile.c.)
732 (EXTRA_DOT_X_FILES, EXTRA_DOT_DOC_FILES): New variables.
733 (guile-procedures.txt): Depend on EXTRA_DOT_DOC_FILES.
734 (modinclude_HEADERS): Removed kw.h.
736 * guile-snarf.in: Change regexp "^SCM__I" --> "^ *SCM__I".
737 (The preprocessor might insert spaces before the identifier.)
739 * snarf.h (SCM_SNARF_HERE, SCM_SNARF_INIT, SCM_SNARF_DOCS):
740 Renamed from SCM_HERE, SCM_INIT, SCM_DOCS.
742 * smob.h (scm_smobfuns): Removed deprecated type.
744 * smob.c, smob.h (scm_newsmob): Removed deprecated function.
745 (Replaced by `scm_make_smob_type'.)
747 * keywords.c (scm_tc16_kw): Removed deprecated type.
748 (Replaced by scm_tc16_keyword.)
750 * kw.h: Removed deprecated header file.
752 * evalext.c (serial-map): Removed deprected alias for scm_map.
753 (Has been replaced by `map-in-order'.)
755 * ramap.c (serial-array-copy!, serial-array-map!): Removed
756 depracted aliases. (Replaced by `array-copy-in-order!' and
757 `array-map-in-order'.)
759 2000-06-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
761 * gc.h (SCM_VALIDATE_CELL): Rewritten.
762 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
763 SCM_SET_CELL_OBJECT): Use new version of SCM_VALIDATE_CELL.
764 (Thanks to Han-Wen Nienhuys.)
766 2000-06-10 Michael Livshin <mlivshin@bigfoot.com>
768 * guile-doc-snarf.in: don't pipe the CPP output right into sed --
769 write it to the temp file first and check the CPP return code.
770 (I introduced this bug earlier, and this probably caused people
771 with non-GNU C preprocessors to get empty *.x files and not to
772 have the build fail right away...).
774 * scmsigs.c (s_scm_sigaction): guard the SIGSYS case with an ifdef
775 -- at least my libc5-based Linux system doesn't define SIGSYS.
777 2000-06-08 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
779 * snarf.h, guile-snarf.awk.in, guile-snarf.in: Replaced snarf
780 markers with identifiers (SCM__I, SCM__D, SCM__S, SCM__E).
781 (Thanks to Bernard Urban.)
783 2000-06-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
785 * modules.c (scm_system_module_env_p): Fixed detection of system
788 2000-06-06 Marius Vollmer <mvo@zagadka.ping.de>
790 * scmsigs.c (scm_sigaction): Silently ignore setting handlers for
791 `program error signals' because they can't currently be handled by
794 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
796 * procs.h (SCM_SET_SUBRF): Added.
798 * procs.c (scm_make_subr_opt): Don't assign to SCM_SUBRF, use
799 SCM_SET_SUBRF instead. Thanks to Bernard Urban for the bug
802 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
804 * gc.h (SCM_CARLOC, SCM_CDRLOC): Don't take the address of a SCM
807 * sort.c (scm_sorted_p, scm_merge, scm_merge_list_x,
808 scm_merge_list_step): Don't take the address of SCM_CAR. Use
809 SCM_CARLOC instead. Thanks to Bernard Urban for the bug report.
811 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
813 * boolean.h (SCM_TRUE_P): Removed, as people might use it as a
814 replacement for !SCM_FALSEP.
816 * backtrace.c (display_error_body), boolean.h (SCM_BOOLP), gc.c
817 (scm_unhash_name), gh_data.c (gh_module_lookup), load.c
818 (scm_primitive_load), print.c (scm_simple_format), procs.c
819 (scm_procedure_documentation), procs.h (SCM_TOP_LEVEL), ramap.c
820 (scm_array_fill_int), scmsigs.c (scm_sigaction), stacks.c
821 (narrow_stack, scm_make_stack, scm_stack_id), symbols.c
822 (scm_string_to_obarray_symbol), throw.c (scm_catch,
823 scm_lazy_catch, scm_ithrow), unif.c (scm_make_uve, scm_array_p,
824 scm_array_set_x, scm_bit_set_star_x, scm_bit_count_star),
825 validate.h (SCM_VALIDATE_BOOL_COPY, SCM_VALIDATE_PROC): Replace
826 uses of SCM_TRUE_P (x) with SCM_EQ_P (x, SCM_BOOL_T).
828 2000-06-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
830 * eval.c (scm_badformalsp): New static function.
831 (SCM_CEVAL): Check arguments for procedure-with-setter closures.
832 (Thanks to Keisuke Nishida.)
834 The major reason for Guile's slow loading speed has been the fact
835 that a chain of Scheme level procedures has been evaluated for
836 every top-level symbol lookup during the first pass through the
839 The following is a kludge which I suggested four years ago, and
840 which I've repeatedly suggested since. Personally, I've never
841 been bothered by Guile's slow loading speed, so I thought I would
842 let someone else do it...
844 But since the new environments will be included first in
845 Guile-1.5, I thought it would make people happy to get the kludge
848 * modules.c: Added #include "libguile/vectors.h";
849 Added #include "libguile/hashtab.h";
850 Added #include "libguile/struct.h";
851 Added #include "libguile/variable.h";
852 Capture Scheme level `module-make-local-var!' to be used in the
853 standard eval closure.
854 (scm_standard_eval_closure): New primitive.
856 * modules.h (scm_standard_eval_closure): Declare.
858 * eval.c (scm_lookupcar): Test for !SCM_CONSP (SCM_CAR (env))
859 instead of SCM_TRUE (scm_procedurep (SCM_CAR (env))).
861 * symbols.c (scm_sym2vcell): Bypass dispatch in the evaluator for
862 standard eval closures.
864 * variable.c: Code layout fixes.
866 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
868 * Makefile.am: Added LIBS line to libpath which accidentally
869 disappeared in the change of 2000-06-01.
870 (Thanks to Dale P. Smith.)
872 2000-06-03 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
874 * scmsigs.c (scm_segfault): Removed. (Was probably added by
875 mistake since it is not mentioned in ChangeLog.)
877 * gc.h (SCM_VALIDATE_CELL): Cast result to (void) in order to
878 avoid compiler warnings in gcc. (Does this work for other
881 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
883 * gc.h (SCM_VALIDATE_CELL): Don't "use" the value returned by
885 (SCM_CARLOC, SCM_CDRLOC): Define directly instead of using
886 SCM_CELL_OBJECT_0 and SCM_CELL_OBJECT_1. It's not correct to take
887 the address of these expressions since they use SCM_VALIDATE_CELL.
888 (Thanks to Bernard Urban.)
890 * dynl.c: Changed #include <ltdl.h> --> #include
891 "libltdl/ltdl.h". (Thanks to Bill Schottstaedt.)
893 2000-06-01 Craig Brozefsky <craig@red-bean.com>
895 * Makefile.am: libguile_la_LDFLAGS gets -version-info args
896 from GUILE-VERSION definition of LIBGUILE version. Added to
897 libpath.h definitions for guileversion and libguileversion which
898 both get their values from GUILE-VERSION definition.
900 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
902 * numbers.h (SCM_BIGP): Don't use SCM_SMOB_PREDICATE in header
903 file: Code using numbers should not be required to include
906 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
908 * coop-threads.c.cygnus, coop-threads.h.cygnus, fsu-pthreads.h,
909 mit-pthreads.c, mit-pthreads.h: Deleted.
911 * Makefile.am (EXTRA_DIST), scmsigs.c, threads.[ch]: Drop
912 references to deleted files and fsu/mit thread support in
915 2000-05-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
917 * hooks.c (symbol_name, scm_create_hook): Restored the original
918 behaviour of scm_create_hook. Changing it was bad as Carl
919 R. Witty has pointed out.
921 * gc.c (scm_init_gc): We can still rely on scm_create_hook to
924 2000-05-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
926 * gc.c (scm_init_gc): Protect scm_after_gc_hook, since this will
927 soon not be done by scm_create_hook any longer.
929 * hooks.c (make_hook, print_hook, scm_create_hook,
930 scm_make_hook_with_name, scm_make_hook), hooks.h (SCM_HOOK_NAME,
931 SCM_HOOK_PROCEDURES, SCM_SET_HOOK_PROCEDURES,
932 scm_make_hook_with_name), init.c (scm_boot_guile_1): Hooks no
933 longer have names. As an intermediate solution, the name
934 predicate is emulated via object properties, but use of this
935 feature is deprecated.
937 * hooks.h (scm_free_hook): Removed, as it is never defined.
939 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
941 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_FIXABLE):
942 Un-deprecated since otherwise user code can't determine whether a
943 number fits into an inum any longer. The names should be changed
946 * numbers.c (scm_big2inum): Eliminated use of SCM_UNEGFIXABLE.
948 * tags.h (SCM_UNPACK_CAR): Deprecated.
950 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
952 * filesys.h (SCM_OPDIRP), fluids.h (SCM_FLUIDP, SCM_FLUID_NUM),
953 fports.h (SCM_OPFPORTP, SCM_OPINFPORTP, SCM_OPOUTFPORTP), hooks.h
954 (SCM_HOOK_ARITY), keywords.h (SCM_KEYWORDP, SCM_KEYWORDSYM),
955 numbers.h (SCM_NUMP, SCM_BIGSIGN, SCM_BDIGITS, SCM_NUMDIGS):
956 Replace SCM_UNPACK_CAR appropriately. Don't access cells via
957 SCM_{SET}?C[AD]R unless they are known to be cons cells.
959 * gc.c (scm_heap_seg_data_t, scm_mark_locations, scm_cellp,
960 init_heap_seg): Remove unused struct member variable 'valid'.
962 2000-05-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
964 * fports.c (fport_write), ports.c (scm_markstream, scm_port_mode,
965 scm_print_port_mode), ports.h (SCM_OPPORTP, SCM_OPINPORTP,
966 SCM_OPOUTPORTP, SCM_INPUT_PORT_P, SCM_OUTPUT_PORT_P, SCM_OPENP),
967 procs.h (SCM_CLOSCAR), unif.h (SCM_ARRAY_NDIM, SCM_ARRAY_CONTP),
968 variable.h (SCM_VARIABLEP): Replace SCM_UNPACK_CAR
971 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
973 * gc.c (free_list_length), hash.c (scm_hasher), macros.c
974 (scm_macro_type), objects.c (scm_class_of), options.c
975 (scm_options), print.c (scm_iprin1), strports.c (st_seek), throw.c
976 (SCM_LAZY_CATCH_P): Replace SCM_UNPACK_CAR appropriately.
978 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
980 * eval.c (scm_macroexp, SCM_CEVAL, scm_force), tags.h: Replace
981 SCM_UNPACK_CAR with SCM_CELL_TYPE or SCM_CELL_WORD_0.
983 * eval.c (scm_force): Add documentation.
985 * eval.c (scm_force, scm_cons_source): Don't access cells via
986 SCM_{SET}?C[AD]R unless they are known to be cons cells.
988 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
990 * strings.h (SCM_NSTRINGP, SCM_NRWSTRINGP), tags.h
991 (SCM_NDOUBLE_CELLP), vectors.h (SCM_NVECTORP): Deprecated.
993 * gc.c (scm_igc), gc.h (SCM_PTR_MASK, SCM_PTR_LT): Removed #ifdef
994 nosve #endif conditionally compiled code.
996 2000-05-23 Michael Livshin <mlivshin@bigfoot.com>
998 * gc.c (scm_heap_seg_data_t): fixed comment for the `span' member.
1000 2000-05-22 Michael Livshin <mlivshin@bigfoot.com>
1002 * guile-doc-snarf.in: put the preprocessed file through sed to
1003 trim all lines to 1024 chars. I hope it doesn't break anybody's
1004 sed. we'll see. (note: this is lossy trimming, i.e. the spill
1005 isn't wrapped around but actually chopped off. this seemed to me
1006 safe because the current snarfer doesn't understand multi-line
1007 cookies anyway. in the long term, it would be nice not to depend
1008 on AWK for anything.)
1010 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): reverted
1011 the previous change to this macros, after deciding to torture the
1014 2000-05-21 Michael Livshin <mlivshin@bigfoot.com>
1016 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): brought
1017 the yucky, ugly and nasty conditional compilation back. sorry,
1018 but it was either that or requiring GAWK to build Guile.
1019 (lots of places): removed the code that implemented the old GC
1022 * init.c (scm_boot_guile_1): removed the code conditioned on
1023 !GUILE_NEW_GC_SCHEME.
1025 * __scm.h: (GUILE_NEW_GC_SCHEME): removed.
1027 * gc.c (scm_protect_object, scm_unprotect_object): change the
1028 implementation to more efficient (at least in the time complexity
1029 sense). the calls should now also be thread-safe -- I suspect
1030 that people expect them to be. (thanks to Han-Wen Nienhuys)
1031 (lots of places): removed the code that implemented the old GC
1034 * hashtab.c (scm_hash_fn_create_handle_x): add missing
1035 SCM_REALLOW_INTS before return. I really wonder about the
1036 possible interactions between hashtables, threads & GC. it
1037 doesn't look healthy at all.
1039 2000-05-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
1041 * unif.c (scm_bit_count): Fixed the parameter checks. Thanks to
1044 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
1046 * __scm.h (SCM_DEBUG_CELL_ACCESSES), gc.h (SCM_): Added as a new
1047 debug option to verify all accesses to cells actually access
1048 objects on the heap.
1050 * gc.h (SCM_VALIDATE_CELL): Added. Only performs validation if
1051 SCM_DEBUG_CELL_ACCESSES is set to 1.
1053 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
1054 SCM_SET_CELL_OBJECT): Use SCM_VALIDATE_CELL to check every cell
1057 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
1059 * gh_data.c (gh_scm2chars, gh_scm2shorts, gh_scm2longs,
1060 gh_scm2floats, gh_scm2doubles): Change !SCM_NIMP to SCM_IMP.
1062 * gc.c (scm_cellp): Fixed and simplified.
1064 * throw.c (JBJMPBUF, SETJBJMPBUF, SCM_JBDFRAME, SCM_SETJBDFRAME,
1065 make_jmpbuf, scm_init_throw): Now using double cells to represent
1066 jump buffers when using debug extensions.
1070 2000-05-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
1072 * gh.h gh_data.c gh_funcs.c (gh_new_procedure*, gh_chars2byvect,
1073 gh_shorts2svect, gh_longs2ivect, gh_ulongs2uvect, gh_floats2fvect,
1074 gh_doubles2dvect, gh_doubles2scm, gh_define, gh_lookup,
1075 gh_module_lookup): Accept const pointers as parameters.
1077 * gh.h gh_data.c (gh_int2scmb): Deprecated.
1079 2000-05-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
1081 * __scm.h (SCM_DEBUG_REST_ARGUMENT): Renamed from
1082 SCM_DEBUG_REST_ARGUMENTS in order to clarify that we don't test
1083 the actual arguments in the list, but rather the rest argument as
1084 a list of arguments.

1096 scm_dynamic_link, scm_init_dynamic_linking), dynl.h
1097 (scm_dynamic_link): Removed possibility to pass flags to
1098 scm_dynamic_link, as it had no effect anyway.
1100 * filesys.c (scm_fcntl): Made single optional rest argument into
1101 a standard optional argument.
1103 * hooks.c (scm_run_hook): A list of rest arguments is never
1106 * list.c (scm_append, scm_append_x), stacks.c (scm_make_stack),
1107 strings.c (scm_string_append): Don't perform half-hearted checks
1108 to see whether the rest argument forms a proper list any more, use
1109 SCM_VALIDATE_REST_ARGUMENTS instead.
1111 * ports.c (scm_close_all_ports_except): Accept empty list of rest
1114 * posix.c (scm_convert_exec_args), print.c (scm_simple_format):
1115 Simplify verification of rest argument.
1117 * stacks.c (scm_make_stack), stacks.h (scm_make_stack), throw.c

1123 scm_enclose_array, scm_array_in_bounds_p): Make first mandatory
1124 rest argument into a standard mandatory argument.
1126 2000-05-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
1128 * __scm.h: Added SCM_DEBUG as default debug option. (Thanks to
1129 Keisuke Nishida for the suggestion.) Added debug option
1130 SCM_DEBUG_REST_ARGUMENTS.
1132 * eval.c (scm_map, scm_for_each): Make sure all lists have the
1133 same length. Also, removed redundant parameter checks.

1139 * __scm.h: Improved explanation of giving options to make.
1141 * __scm.h (SCM_DEBUG_TYPING_STRICTNESS), tags.h
1142 (SCM_STRICT_TYPING, SCM_DEBUG_TYPING_STRICTNESS): Renamed
1143 SCM_STRICT_TYPING to SCM_DEBUG_TYPING_STRICTNESS and moved the
1144 corresponding declaration and comment to __scm.h.

1147 (scm_remainder, scm_modulo), numbers.h (SCM_SRS, SCM_MAKINUM,
1148 SCM_INUM): Removed conditionally compiled code for Turbo C.
1150 * gdbint.c (gdb_maybe_valid_type_p): Eliminated call to scm_tag.
1151 That check can be assumed to be redundant except for very rare
1152 conditions that actually indicate broken heap data.
1154 2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
1156 * numbers.c (scm_logcount, scm_integer_length): Reordered
1159 2000-05-15 Gary Houston <ghouston@arglist.com>
1161 * stime.c (scm_strftime): don't reset TZ if zone is an empty
1162 string. append a "0" to the zone for TZ.
1164 2000-05-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
1166 * numbers.c (scm_logbit_p, scm_bit_extract): Reordered dispatch
1169 (scm_bit_extract): Fixed handling of bignums.
1171 2000-05-15 Dirk Herrmann <D.Herrmann@tu-bs.de>

1181 (scm_tc16_flo, scm_tc_flo, scm_tc_dblr, scm_tc_dblc): Wrapped
1182 deprecated code between #if (SCM_DEBUG_DEPRECATED == 0) #endif.
1184 * fports.c (scm_fport_buffer_add), ports.c (scm_input_port_p,
1185 scm_output_port_p), print.c (scm_get_print_state), validate.h
1186 (SCM_VALIDATE_CHAR): Replace use of deprecated macros
1187 SCM_INPORTP, SCM_OUTPORTP, SCM_ICHRP by SCM_INPUT_PORT_P,
1188 SCM_OUTPUT_PORT_P, SCM_CHARP, respectively.
1190 2000-05-14 Gary Houston <ghouston@arglist.com>
1192 * stime.c (scm_strftime): if HAVE_TM_ZONE is not defined, hack the
1193 TZ environment variable so that the %Z format returns the zone
1194 from the input vector instead of the system default.
1196 from Keisuke Nishida:
1197 * fports.c (scm_setvbuf): minor docstring fix.
1198 * ports.h (scm_generic_fgets): obsolete prototype deleted.
1200 2000-05-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
1202 * __scm.h: Added new section for debugging options.
1204 (SCM_DEBUG_DEPRECATED): If 1, no deprecated code is included to
1205 help developers to get rid of references to deprecated code.
1207 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_UNEGFIXABLE,
1208 SCM_FIXABLE, SCM_FLOBUFLEN): These macros are no longer provided
1209 as part of the interface and are marked as deprecated in the
1212 * numbers.c (scm_make_real, scm_make_complex): Inlined the
1213 corresponding macros SCM_NEWREAL and SCM_NEWCOMPLEX,
1216 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX, SCM_INEXP, SCM_CPLXP,
1217 SCM_REAL, SCM_IMAG, SCM_REALPART, scm_makdbl, SCM_SINGP,
1218 SCM_NO_BIGDIG, SCM_NUM2DBL, scm_dblproc): Deprecated.
1220 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1222 * gc.h (scm_cell, SCM_CELL_WORD, SCM_CELL_OBJECT,
1223 SCM_SET_CELL_WORD, SCM_SET_CELL_OBJECT): Scheme cells now consist
1224 of two scm_bits_t values instead of two SCM values, because it is
1225 legal for cell entries to hold values that are not scheme objects.
1227 (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR):
1228 Use SCM_SETC[AD]R to modify contents of pairs.

1232 * numbers.c (IS_INF, isfinite): Added FIXME comment.
1234 (scm_abs, scm_magnitude): Make these two independent of each
1235 other. scm_abs now reports an error if given a complex argument.
1237 (scm_istr2flo, scm_integer_p). Use SCM_REAL_VALUE instead of
1238 SCM_REALPART if the object is known to be real.
1240 (scm_init_numbers): No need to use SCM_NEWREAL macro for speed
1243 * numbers.h (SCM_SINGP): Set to 0 instead of SCM_BOOL_F.
1245 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1247 * eq.c (scm_eqv_p): Separate handling of real and complex

1251 gh_scm2doubles), hash.c (scm_hasher), ramap.c (scm_array_fill_int,
1252 ramap_rp, scm_array_map_x), random.c (vector_scale,
1253 vector_sum_squares), unif.c (scm_make_uve, scm_array_p,
1254 scm_array_set_x): Use SCM_REAL_VALUE instead of SCM_REALPART if
1255 the object is known to be real. Use SCM_COMPLEXP instead of
1256 deprecated SCM_CPLXP. Use SCM_INEXACTP instead of deprecated
1259 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1261 * numbers.c: No need to include unif.h.
1263 (IS_INF): Returned to old test for now: x == x + 1 will not work
1264 for large numbers due to rounding errors.
1265 Thanks to Kalle Olavi Niemitalo.
1267 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
1269 * numbers.c (scm_divbigdig): Removed outdated comment.
1271 (scm_number_to_string, scm_string_to_number, scm_number_p,
1272 scm_real_p, scm_integer_p, scm_inexact_p, scm_gr_p, scm_leq_p,
1273 scm_geq_p, scm_make_rectangular, scm_make_polar,
1274 scm_inexact_to_exact): Added comments.
1276 (add1, scm_init_numbers): Removed add1.
1278 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
1280 * numbers.c (IS_INF): The new test is x == x + 1. The old test
1281 x == x/2 did not work for zero values. Thanks to Han-Wen Nienhuys
1284 (scm_number_to_string, scm_sum, scm_difference, scm_two_doubles,
1285 scm_num2long, scm_num2long_long, scm_num2ulong): Reordered
1288 2000-05-09 Marius Vollmer <mvo@zagadka.ping.de>
1290 * scmsigs.c (take_signal): Execute SCM_ASYNC_TICK for SIGSEGV,
1291 SIGILL and SIGBUS signals. These signals are not continuable and
1292 must be handled for real right away.
1294 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1296 * numbers.c (scm_zero_p, scm_positive_p, scm_negative_p,
1297 scm_real_part, scm_imag_part, scm_magnitude,
1298 scm_inexact_to_exact): Reordered dispatch sequence.
1300 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1302 * feature.c: No need to include "libguile/smob.h"
1304 (scm_loc_features, features, scm_add_feature, scm_init_feature):
1305 Removed variable 'scm_loc_features' as a pointer to the SCM value
1306 holding the features list. Using variable 'features' instead,
1307 which holds the interned pair. Thus, SCM_SETCDR can be used
1308 instead of pointer trickery.
1310 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1312 * alist.c (scm_acons): Use SCM{_SET}?_CELL_OBJECT as long as a
1313 cell is not known to be a valid pair.
1315 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1317 * eval.c (ASRTSYNTAX, scm_m_body, scm_m_letrec1): Removed
1318 ASRTSYNTAX. Using SCM_ASSYNT instead.
1320 (scm_m_body): Don't create a redundant cons cell.

1324 (bodycheck): Removed.
1326 * stacks.c (stack_depth, read_frame, read_frames): Removed
1327 redundant calculation of size, minimized some variable scopes.
1329 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1331 * pairs.c (scm_cons, scm_cons2): Use SCM{_SET}?_CELL_OBJECT as
1332 long as a cell is not known to be a valid pair.
1334 (scm_pair_p): Eliminated redundant SCM_IMP test.
1336 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1338 * eval.c (scm_m_body, scm_macroexp, unmemocopy, scm_eval_args,
1339 scm_deval_args): Eliminated redundant SCM_IMP tests.
1341 * hashtab.c (scm_ihashx, scm_sloppy_assx, scm_delx_x), weaks.c
1342 (scm_make_weak_key_hash_table, scm_make_weak_value_hash_table,
1343 scm_make_doubly_weak_hash_table): Fixed critical sections.
1344 Thanks to Keisuke Nishida.
1346 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1348 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest):
1349 Fixed some goto-related initialization bugs (introduced by me).
1351 2000-05-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
1353 * numbers.h (SCM_INUM0): Uses SCM_MAKINUM instead of SCM_PACK.
1355 * dynl.c (dynl_obj, DYNL_OBJ, get_dynl_obj): Removed.
1357 (DYNL_FILENAME, DYNL_HANDLE): Use SCM_CELL... macros instead of
1360 (SET_DYNL_HANDLE): Added.
1362 (scm_dynamic_object_p): Simplified.
1364 (scm_dynamic_unlink, scm_dynamic_func): Changed comment. Deliver
1365 better error message when accessing unlinked dynamic objects.
1366 Eliminated call to get_dynl_obj.
1368 2000-05-03 Marius Vollmer <mvo@zagadka.ping.de>
1370 * scmsigs.c (orig_handlers) [!HAVE_SIGACTION]: Fix declaration to
1371 be an array of function pointers instead of being a pointer to an
1372 array returning function. Thanks to Kalle Olavi Niemitalo!
1374 2000-05-03 Dirk Herrmann <D.Herrmann@tu-bs.de>
1376 * numbers.c (scm_divbigbig, scm_divbigint), numbers.h
1377 (scm_divbigbig, scm_divbigint): Don't return zero any more to
1378 indicate that a division has a remainder, return SCM_UNDEFINED
1379 instead. It is improbable that anyone actually used these
1380 functions outside of numbers.c. For this reason and due to the
1381 change in behaviour the functions are static now. Thus, if
1382 surprisingly there are users of these functions they will at least
1385 * numbers.c: Removed #ifdef SCM_BIGDIG #endif in those functions,
1386 that already have a clean dispatch order. Note: SCM_BIGDIG is
1389 * numbers.c (scm_inexact_p): Simplified.
1391 * numbers.c (scm_num_eq_p, scm_less_p, scm_max, scm_min,
1392 scm_product, scm_num2dbl, scm_angle): Reordered dispatch
1393 sequence, thereby fixing some comparisons of SCM values with
1396 * numbers.c (scm_divide): Division by zero of inums leads to an
1397 error now. (Formerly, an infinite number was returned.)
1399 Respect the fact, that scm_divbigbig does now return SCM_UNDEFINED
1400 if a division has a remainder.
1402 2000-05-02 Gary Houston <ghouston@arglist.com>
1404 * Makefile.am (INCLUDES): add ${INCLTDL} (thanks to Tim Mooney).
1406 2000-05-02 Dirk Herrmann <D.Herrmann@tu-bs.de>
1408 * numbers.c (scm_logtest, scm_division): Reordered dispatch
1409 sequence, thereby fixing some comparisons of SCM values with
1412 * numbers.h (scm_makdbl): Mark as deprecated at the point of
1415 * eval.c (SCM_CEVAL, SCM_APPLY), gh_data.c (gh_double2scm,
1416 gh_doubles2scm), numbers.c (scm_istr2flo, scm_max, scm_min,

1420 scm_long2num, scm_long_long2num, scm_ulong2num), ramap.c
1421 (ramap_rp, scm_array_map_x), random.c (scm_random,
1422 scm_random_uniform, scm_random_normal_vector_x, scm_random_exp),
1423 struct.c (scm_struct_ref), unif.c (scm_array_to_list): Replace
1424 call to scm_makdbl with a call to scm_make_real or
1425 scm_make_complex, depending on whether the imaginary part is known
1428 2000-05-01 Gary Houston <ghouston@arglist.com>
1430 * scmsigs.c: fix the definition of orig_handlers for the case
1431 that HAVE_SIGACTION is not defined (thanks to
1432 Kalle Olavi Niemitalo).
1434 * Makefile.am: remove include_HEADERS (was libguile.h)
1435 libguile.h: moved to top level directory.
1437 2000-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1439 * numbers.c (SCM_SWAP): Moved to the top of the file to allow for
1442 * numbers.c (scm_modulo, scm_gcd, scm_lcm, scm_logand, scm_logior,
1443 scm_logxor): Reordered dispatch sequence, thereby fixing some
1444 comparisons of SCM values with integer constants.
1446 * number.c (scm_logtest): Removed some redundant SCM_{N}?IMP
1449 2000-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1451 * numbers.c (scm_quotient, scm_remainder): Removed code that was
1452 conditionally compiled based on BADIVSGNS. BADIVSGNS does not
1453 occur anywhere else throughout guile.
1455 * numbers.c (scm_quotient): Fixed parameter number in error
1458 * numbers.c (scm_remainder): Reordered dispatch sequence.
1460 2000-04-25 Gary Houston <ghouston@arglist.com>

1465 2000-04-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
1467 * eval.c (undef_object): Made into a local static variable
1468 (suggested by Jost Boekemeier).
1470 2000-04-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
1472 * pairs.c (cxrs, scm_init_pairs): Simplify initialization of
1475 * procs.c (scm_init_iprocs), procs.h (scm_subr, scm_iproc,
1476 scm_dsubr, scm_init_iprocs): Removed.
1478 * procs.h (SCM_SUBRF, SCM_DSUBRF): Access the cell words
1479 directly instead of casting a cell to a C struct.
1481 2000-04-22 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1483 Better modularization of GC extensions through new C level GC
1486 * weaks.c (scm_weaks_prehistory): New function: Add
1487 scm_weak_vector_gc_init to scm_before_mark_c_hook; Add

1489 (scm_scan_weak_vectors): New function; added to
1490 scm_after_sweep_c_hook.
1492 * weaks.h (scm_weak_vectors, scm_weaks_prehistory): Added
1495 * guardians.h (scm_guardian_gc_init, scm_guardian_zombify): Are
1498 * guardians.c (scm_guardian_gc_init): Turned into a hook function
1499 and added to scm_before_mark_c_hook.
1500 (scm_guardian_zombify): Turned into a hook function and added to
1501 scm_before_sweep_c_hook.
1503 * async.c (scm_sys_gc_async_thunk): Run after-gc-hook.
1504 Added #include "libguile/gc.h".
1506 * gc.h: Added #include "libguile/hooks.h".
1508 * gc.c: Removed #include "libguile/guardians.h".
1509 (scm_before_gc_c_hook, scm_before_mark_c_hook,
1510 scm_before_sweep_c_hook, scm_after_sweep_c_hook,
1511 scm_after_gc_c_hook): New C level hooks.
1512 (scm_after_gc_hook): New Scheme level hook.
1513 (scm_gc_sweep): Moved scanning of weak vectors to weaks.c.
1514 (scm_igc): Moved initialization of scm_weak_vectors and the call
1515 to scm_guardian_gc_init to respective module.
1516 (scm_mark_weak_vector_spines): Moved to weaks.c;
1517 Call to scm_guardian_zombify moved to guardians.c;
1518 Run scm_before_gc_c_hook, scm_before_sweep_c_hook,
1519 scm_after_gc_c_hook at appropriate places.
1520 (scm_init_gc): Initialize scm_after_gc_hook.

1535 (Thanks to Tim Mooney.)
1537 * Makefile.am (INCLUDES): Removed THREAD_CPPFLAGS and INCLTDL.
1538 (DEFS): Added. automake adds -I options to DEFS, and we don't
1540 Removed all -I options except for the root source directory and
1541 the root build directory.
1543 * numbers.c (scm_odd_p, scm_even_p): Use SCM_WRONG_TYPE_ARG
1544 instead of SCM_ASSERT (0, ...). (Some compilers will complain
1545 about control reaching end of function otherwise, and, besides,
1546 the new code is not less clear.)
1548 * gc.c (scm_must_malloc, scm_must_realloc, scm_must_free): Added
1549 calls to malloc debugging functions.

1562 documentation strings.
1564 * numbers.c (scm_exact_p, scm_odd_p, scm_even_p, scm_abs,
1565 scm_quotient): Reordered dispatch sequence to first handle
1566 immediates, second handle bignums and finally handle generic
1567 functions respectively signal wrong type arguments. Hopefully
1568 this will allow for easier separation when goops is integrated.
1570 2000-04-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
1572 * gc.c (which_seg): Use SCM2PTR to convert a non immediate SCM
1573 variable into a pointer to a heap cell.
1575 * gc.c (scm_mark_locations, scm_cellp, init_heap_seg,
1576 scm_unhash_name): Remove redundant cast to SCM_CELLPTR.

1581 SCM_UNDEFINED instead.
1583 * weaks.c (scm_make_weak_vector): Fix assignment of zero to a
1584 vector element. (Still to be improved)
1586 2000-04-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
1588 * eval.c (undef_cell): Removed, replaced by:

1857 * async.h: kill the scm_async_t struct. having a heap cell

1929 separate loop after processing all the currently known live
1930 guardians, so as to not introduce order dependencies (thanks to
1931 Gary Houston). note that the order problems are still there if
1932 some guardians are themselves zombies, but that's a sick case that
1933 I'm not going to worry about.
1934 also, make another outer loop to process zombified

2071 * ports.h (SCM_SETPTAB_ENTRY, SCM_SETSTREAM): Cast input to
2074 2000-03-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2076 * coop-defs.h (struct coop_t): Added `sto'-field again because of
2077 binary compatibility---let's remove it next time we alter some
2080 * coop.c (coop_quitting_p, coop_cond_create, coop_mutex_create,
2081 coop_mother, coop_child): New variables.
2082 (mother): New function.
2083 (coop_create): New thread spawning mechanism which uses a "mother
2084 thread". The "dummy" pthreads aren't healthy enough to give birth
2085 to new threads since Linux threads thinks they are asleep.
2087 * coop-defs.h (struct coop_t): Removed dummy_mutex.
2089 * coop-defs.h, coop-threads.c (struct coop_t): Eliminate
2090 `sto'-field when GUILE_PTHREAD_COMPAT is enabled.
2092 2000-03-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
2094 * arbiters.c (scm_make_arbiter), async.c (scm_async), dynwind.c
2095 (scm_internal_dynamic_wind): Smob data is always of type
2098 * arbiters.c (SCM_ARB_LOCKED, SCM_LOCK_ARB, SCM_UNLOCK_ARB):
2099 Access the locking information in cell entry 0 with
2100 SCM_{SET_}?CELL_WORD_0 instead of SCM_*CAR.
2102 * async.c (scm_run_asyncs): Use SCM_NULLP to test for the empty
2105 * dynwind.c (scm_dowinds): Use SCM_EQ_P to compare SCM values.
2107 * ports.h (SCM_PTAB_ENTRY, SCM_SETPTAB_ENTRY): Access the ptab
2108 entry data using SCM_{SET_}?CELL_WORD_1 instead of SCM_{SET}?CDR.
2110 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
2112 * alist.c (scm_sloppy_assq, scm_assq), eq.c (scm_eq_p, scm_eqv_p,
2113 scm_equal_p), list.c (scm_ilength, scm_last_pair, scm_reverse,
2114 scm_sloppy_memq, scm_delq_x, scm_delq1_x), tags.h (SCM_UNBNDP):
2115 Don't use C operators == and != to compare SCM values, use
2118 * boolean.c (scm_boolean_p): Use SCM_BOOLP to determine whether a
2119 SCM value is equal to #t or #f.
2121 * eq.c (scm_eqv_p, scm_equal_p): Don't use SCM_CAR to access the
2122 cell type entry of non immediate objects of unknown type. Use
2123 SCM_CELL_TYPE instead.
2125 * gh_data.c (gh_scm2bool, gh_module_lookup), list.c
2126 (scm_sloppy_memv, scm_sloppy_member, scm_delv_x, scm_delete_x,
2127 scm_delv1_x, scm_delete1_x), scmsigs.c (scm_sigaction): Use
2128 SCM_FALSEP and SCM_TRUE_P to compare SCM values against #f and
2131 * list.c (scm_listify): Use SCM_UNBNDP to test for an unbound
2134 2000-03-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2136 * coop-threads.c (scm_call_with_new_thread, scm_spawn_thread,
2137 scm_make_mutex, scm_make_condition_variable): Cast data to
2138 scm_bits_t in SCM_SET_CELL_WORD and SCM_NEWSMOB macros.
2140 * coop.c (coop_create): Set `specific' field, not `data' to NULL.
2142 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
2144 * smob.h (SCM_NEWSMOB, SCM_NEWSMOB2, SCM_NEWSMOB3, SCM_SMOB_DATA,
2145 SCM_SET_SMOB_DATA, SCM_TC2SMOBNUM, SCM_SMOBNUM): To access smob
2146 data, use SCM_{SET_}?CELL_TYPE or SCM_{SET_}?WORD_[1-3].
2148 Note that this implies that smob data has always to be passed as
2149 values of type scm_bits_t.
2151 2000-03-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2153 * threads.c (scm_init_threads): Pass 0 size to scm_make_smob_type
2154 for scm_tc16_thread. As the current COOP threads are written, GC
2155 is not supposed to manage storage for threads.
2157 * error.c (scm_error): Don't try to throw an error if
2158 scm_gc_heap_lock is true.
2160 * coop.c (coop_finish): New function. Called at exit.
2161 (coop_aborthelp): Free thread structures when threads die.
2162 Finished LinuxThreads compatibility support => COOP threads now
2163 mesh with LinuxThreads.
2165 * coop-threads.c (scm_call_with_new_thread, scm_spawn_thread):
2166 Changed SETCDR --> SET_CELL_WORD_1.
2168 * coop-threads.c (scheme_launch_thread): Set word 1 of handle to 0
2171 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
2173 * boolean.h (SCM_TRUE_P): New macro.
2175 * boolean.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOLP), pairs.h
2176 (SCM_NULLP, SCM_NNULLP): Use SCM_EQ_P to compare SCM values.
2178 2000-03-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
2180 * continuations.h (SCM_CONTREGS, SCM_SET_CONTREGS): New macros to
2181 access continuation data.
2183 (SCM_SETJMPBUF): Deprecated. Use SCM_SET_CONTREGS instead.
2185 (SCM_JMPBUF, SCM_DYNENV, SCM_THROW_VALUE, SCM_BASE, SCM_SEQ,
2186 SCM_DFRAME): Use SCM_CONTREGS instead of SCM_CHARS to access
2189 * continuations.c (scm_make_cont), init.c (start_stack),
2190 root.c (scm_internal_cwdr): Use SCM_SET_CONTREGS instead of
2193 2000-03-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
2195 * symbols.h (SCM_LENGTH, SCM_SETLENGTH): Access the length field
2196 of strings and symbols by using SCM_{SET_}?CELL_WORD_0.
2198 (SCM_CHARS, SCM_UCHARS, SCM_SETCHARS): Use SCM_{SET_}?CELL_WORD_1
2199 to access the char * field of strings and symbols.
2201 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
2203 * gc.h (SCM_NEWCELL, SCM_NEWCELL2): Use SCM_SET_CELL_TYPE to set
2204 the type entry of a new cell. Added a comment about things to
2205 remember when updating the list of free cells.
2207 (SCM_FREEP, SCM_MARKEDP): Use SCM_CELL_TYPE to access the type
2210 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
2212 * pairs.h (SCM_CAR, SCM_CDR, SCM_SETCAR, SCM_SETCDR): Use
2213 SCM_CELL_OBJECT and SCM_SET_CELL_OBJECT. This change implies that
2214 with strict type checking enabled these macros will only work if
2215 given valid SCM parameters.
2217 (SCM_GCCDR): Moved to tags.h.
2219 * tags.h (SCM_GCCDR): Moved here from pairs.h.
2221 2000-03-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
2223 * tags.h (SCM2PTR, PTR2SCM): Moved to gc.h.
2225 * pairs.h (scm_cell, SCM_CELLPTR, SCM_CELL_WORD*, SCM_CELL_OBJECT*,
2226 SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*, SCM_CELL_TYPE,
2227 SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK, SCM_PTR_GT,
2228 SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC, SCM_NEWCELL,
2229 SCM_NEWCELL2): Moved to gc.h.
2231 (SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR, SCM_SETAND_CDR,
2232 SCM_SETOR_CAR, SCM_SETOR_CDR): Moved to gc.h. These names should
2233 be changed, though, since the macros are not only pair related.
2237 * gc.h (SCM2PTR, PTR2SCM, scm_cell, SCM_CELLPTR, SCM_CELL_WORD*,
2238 SCM_CELL_OBJECT*, SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*,
2239 SCM_CELL_TYPE, SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK,
2240 SCM_PTR_GT, SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC,
2241 SCM_NEWCELL, SCM_NEWCELL2, SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR,
2242 SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR): Moved here from
2245 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2247 * tags.h (SCM_STRICT_TYPING): New macro that, if defined,
2248 activates strict compile time type checking for variables of
2250 (SCM, SCM_PACK, SCM_UNPACK): Define according to whether
2251 SCM_STRICT_TYPING or SCM_VOIDP_TEST are defined.
2252 (SCM_EQ_P): Defined as a macro equivalent for eq?.
2254 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2256 * tags.h (SCM_POINTERS_MUNGED): Removed.
2258 * gc.c (scm_gc_sweep, init_heap_seg): Removed use of
2259 SCM_POINTERS_MUNGED, thus fixing some illegal casts to SCM.
2261 2000-03-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
2263 * pairs.h (SCM_CELL_OBJECT, SCM_CELL_OBJECT_[0-3],
2264 SCM_SET_CELL_OBJECT, SCM_SET_CELL_OBJECT_[0-3], SCM_CELL_TYPE,
2265 SCM_SET_CELL_TYPE): Added a set of low level macros for accessing
2267 (SCM_CELL_WORD_[0-3]): Renamed from the SCM_CELL_WORD[0-3].
2269 * procs.h, procs.c: Instead of SCM_{SET_}?CELL_WORD[12], use the
2270 newly introduced SCM_{SET_}?CELL_OBJECT_[12] macros.
2272 2000-03-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2274 * tags.h: Disabled definition of SCM_VOIDP_TEST.
2276 Defining SCM as void * introduces problems which haven't been
2277 handled yet. Developers who work with these issues can enable it
2278 in their working copies.
2280 Disabling this definition exposes a set of newly introduced and
2281 older misuses of types which causes warning messages during
2282 compilation. We'll fix this successively.
2284 * gc.c (scm_mark_locations): Changed * (SCM **) X --> * (SCM *) X
2285 in order to obtain a value of type SCM.
2286 (scm_cellp): Updated with new changes to scm_mark_locations.
2288 * continuations.h (SCM_SETJMPBUF): Cast second arg into SCM.
2290 * continuations.c (scm_make_cont): Removed cast of size_t into
2293 * symbols.h (SCM_SETCHARS): Cast second arg into SCM.
2295 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
2297 * numbers.h (SCM_SETNUMDIGS): Use SCM_BIGSIZEFIELD macro for
2298 shifting, not constant. Thanks to Dale P. Smith.
2300 * numbers.c (scm_sum, scm_difference): Don't test a SCM value
2301 for being less than zero. Decode it to a C value first. Again,
2304 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
2306 * numbers.h, ramap.c, struct.h, vectors.h: Don't use SCM2PTR for
2307 non scheme values. If raw data is stored in SCM variables, it has
2308 to be accessed using SCM_UNPACK until a better solution is found.
2310 2000-03-22 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2312 * tags.h (SCM_ECONSP, SCM_NECONSP): More corrections of
2313 pointer-arithmetic induced by the SCM_PACK/UNPACK change.
2315 * print.c (scm_iprin1): SCM_PACK/UNPACK corrections.
2317 * gc.c (scm_gc_sweep): SCM_PACK/UNPACK corrections.
2319 * eval.c (SCM_CEVAL, scm_unmemocar): SCM_PACK/UNPACK corrections.
2321 * dynwind.c (scm_swap_bindings): SCM_PACK/UNPACK corrections.
2323 * async.c, __scm.h: Removed lots of the old async click logic. It
2324 is possible to reinsert it by defining GUILE_OLD_ASYNC_CLICK in
2325 __scm.h. Let's try this out and dump the old code after the
2326 threads reorganization.
2327 (set-tick-rate, set-switch-rate): Conditionally removed.
2329 2000-03-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2331 * gc.c (scm_gc_mark): Bugfix 1: The recent SCM_PACK/UNPACK change
2332 made SCM values into pointers. This turned an arithmetic
2333 computation of the address of the vcell into a pointer-arithmetic
2334 one, thereby screwing up marking of structs.
2335 Bugfix 2: Removed incompletely introduced loop variable `j' used
2336 when protecting the tail array of a struct.
2338 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2340 * struct.h (SCM_STRUCT_DATA): Don't cast SCM values to pointers.
2342 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2344 * symbols.h, symbols.c (scm_strhash): Declare the string
2345 parameter as constant, since it is not modified.
2347 * symbols.c (scm_intern_obarray_soft,
2348 scm_sysintern0_no_module_lookup): Can now pass constant strings
2349 to scm_strhash without need for casting.
2351 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2353 * vectors.h (SCM_VELTS, SCM_VELTS_AS_STACKITEMS): Don't cast SCM
2354 values to pointers. Use SCM2PTR instead.
2356 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2358 * async.c (scm_set_tick_rate, scm_set_switch_rate): Don't unpack
2359 results of SCM_INUM.
2361 2000-03-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2363 * init.c (scm_boot_guile_1): Renamed GUILE_GC_TRIGGER_1 -->
2364 GUILE_MIN_YIELD_1, GUILE_GC_TRIGGER_2 --> GUILE_MIN_YIELD_2.
2365 GUILE_MIN_YIELD_X now take *positive* fractions of heap size.
2367 * gc.c, gc.h (SCM_MIN_YIELD_1, SCM_MIN_YIELD_2,
2368 min_yield_fraction, min_yield, adjust_min_yield): Renamed from
2369 SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2, gc_trigger_fraction,
2370 gc_trigger, adjust_gc_trigger.
2372 * gc.c (alloc_some_heap): Further improvement of minimal heap size
2374 (SCM_MAX): New macro.
2375 (scm_freelist_t): New field: collected_1. Previous amount of
2377 (gc_sweep_freelist_finish): Trigger based on two last values of
2378 freelist->collected to avoid unnecessary allocation due to
2380 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2):
2381 Adjusted to 45000 cells, 40% and 40%. Gives quick startup
2382 without extra heap allocation.
2384 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2386 * numbers.h (SCM_MAKINUM): The parameter to SCM_MAKINUM should
2387 already be a C value. No need to unpack it.
2389 * numbers.c (scm_long_long2num): Cast the parameter to scm_bits_t
2390 if we know it fits into an inum.
2392 * ramap.c (ramap_rp): An scm_tc7_[ui]vect object does point to a
2393 field of long values. In contrast, SCM_VELTS accesses a field of
2396 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2398 * gc.c (scm_gc_stats): Inserted explanation of local_scm_mtrigger
2400 (scm_gc_yield_1): New variable: Holds previous yield. Used to
2401 make better judgements.
2402 (gc_sweep_freelist_finish): Inserted explanation of use of
2405 * print.h, stacks.h, options.c, options.h: Changed C++
2408 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2410 * tags.h (SCM2PTR, PTR2SCM): Use SCM_PACK / SCM_UNPACK correctly.
2412 * numbers.h (SCM_INUMP, SCM_MAKINUM, SCM_INUM0, SCM_COMPLEX_REAL,
2413 SCM_COMPLEX_IMAG, SCM_NUMP, SCM_BDIGITS): Use SCM_PACK /
2414 SCM_UNPACK / SCM2PTR correctly.
2416 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2418 * gc.c (adjust_gc_trigger): Improved documentation.
2419 (alloc_some_heap): Since gc_trigger is used against
2420 freelist->collected, this is the value which should be used to
2421 predict minimum growth.
2423 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2425 * eval.h: Fix mixup of packed/unpacked SCM values. (Thanks
2426 Thien-Thi Nguyen for the patch.)
2428 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2430 * numbers.c (scm_ash): Fixed typing problems with the second
2431 parameter and added some documentation. (Thanks Thien-Thi Nguyen
2432 for indicating the problem.)
2434 2000-03-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2436 * gc.c, gc.h (scm_gc_yield): New variable.
2437 (adjust_gc_trigger): Use scm_gc_yield.
2438 (alloc_some_heap): Use scm_gc_yield instead of
2439 scm_gc_cells_collected.
2441 * coop-threads.c: Addd #include "root.h", #include "strings.h".
2443 * debug.c: Added #include "root.h". (Thanks to Thien-Thi Nguyen.)
2445 * gc.c (scm_gc_for_newcell, adjust_gc_trigger): Improved GC
2446 trigger adjustmeant: Take yield (freed cells) for all freelists
2448 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Tuned
2449 to 50000 cell heap with 45% trigger.
2450 (scm_gc_cells_collected): Reintroduced.
2451 (SCM_HEAP_SIZE): New macro.
2452 (scm_gc_sweep): Reintroduced correct computation of
2453 scm_cells_allocated.
2454 (scm_freelist_t): Corrected commentary for field `cluster_size':
2455 Clustersize counts objects, not cells; New member
2456 `clusters_allocated'.
2458 2000-03-19 Michael Livshin <mlivshin@bigfoot.com>
2460 * *.[hc]: add Emacs magic at the end of file, to ensure GNU
2463 2000-03-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2465 * threads.h: Added #include "libguile/throw.h". (Thanks to
2468 2000-03-18 Michael Livshin <mlivshin@bigfoot.com>
2470 * tags.h: (SCM_DOUBLE_CELLP, SCM_NDOUBLE_CELLP): new macros (bad
2471 names, anyone got any better ones?)
2473 * gc.h: (typedef struct scm_freelist_t) remove from here.
2475 * gc.c: (CELL_UP, CELL_DN) made these macros take additional
2476 parameter (the span).
2477 (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK) new macros.
2478 (typedef struct scm_freelist_t) moved here from gc.h, it had no
2479 business being externally visible.
2480 (typedef struct scm_heap_seg_data_t) renamed from
2481 scm_heap_seg_data, to be style-compliant.
2482 (scm_mark_locations) if the possible pointer points to a
2483 double-cell, check that it's properly aligned.
2484 (init_heap_seg) align double-cells properly, work with the
2485 assumption that the segment size divides cleanly by cluster size.
2486 (round_to_cluster_size) new function.
2487 (alloc_some_heap, make_initial_segment) use round_to_cluster_size
2488 to satisfy the new init_heap_seg invariant.
2490 2000-03-18 Dirk Herrmann <D.Herrmann@tu-bs.de>

2549 * gc.c, gc.h: Cleanup of the change of 2000-03-15.
2550 Cluster sizes are now independent of GC trigger values.
2551 GUILE_GC_TRIGGER_n can now specify a relative trigger value:
2552 A negative integer gives fraction of total heap size in percent.
2553 (SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Default values set to -40.
2555 * init.c (scm_boot_guile_1): Introduced new variable
2556 GUILE_MAX_SEGMENT_SIZE; New environment variable names:
2557 GUILE_INIT_SEGMENT_SIZE_1, GUILE_GC_TRIGGER_1,
2558 GUILE_INIT_SEGMENT_SIZE_2, GUILE_GC_TRIGGER_2
2560 2000-03-16 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2562 * __scm.h (GC_FREE_SEGMENTS): Disable this until we have made
2563 freeing of segment work with the new GC scheme. (Thanks to
2564 Michael Livshin.) Oops, also happened to make GUILE_NEW_GC_SCHEME
2565 the default, but I'll let this change stay in CVS Guile since this
2566 code is not expected to contain serious bugs.
2568 2000-03-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2570 * gc.c, gc.h (scm_map_free_list): Define also if GUILE_DEBUG is
2572 (scm_free_list_length): New procedure (GUILE_DEBUG).
2573 Fixed a small but serious bug introduced by the previous change.
2575 * gc.c (scm_gc_sweep): Moved variable n_objects to inner sweep
2576 loop and declare as register.
2578 * gc.c (scm_gc_sweep): Sigh... forgot to clear private freelists
2581 Wed Mar 15 08:27:04 2000 Greg J. Badros <gjb@cs.washington.edu>
2583 * fluids.c: Docstring patch from Keisuke Nishida. Some
2584 reindentation, too, and a couple formals renamed. Should
2585 fluid-set! return UNSPECIFIED instead of a value?
2587 Wed Mar 15 08:24:58 2000 Greg J. Badros <gjb@cs.washington.edu>
2589 * Makefile.am: Separate out DOT_X_FILES and DOT_DOC_FILES, and
2590 generate the latter from the concrete listing of the former. Then
2591 make guile-procedures.txt depend on DOT_DOC_FILES instead of
2592 *.doc, so that rebuilding it works.
2594 Wed Mar 15 08:12:14 2000 Greg J. Badros <gjb@cs.washington.edu>
2596 * libguile.h: Include libguile/validate.h. Thanks Keisuke Nishida!
2598 * guile-snarf.awk.in: Replace docstring line-ending \n" and \n\n"
2599 with nothing and \n, respectively. Thanks Keisuke Nishida for
2600 noticing this problem.
2602 2000-03-15 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2604 * __scm.h (GUILE_NEW_GC_SCHEME): Define this if you want to test a
2605 new way of allocating heap. It makes Guile fast, but still
2608 * gc.c, gc.h, pairs.h, init.c: Implementation of a new way of
2609 allocating heap. The basic idea is to trigger GC every Nth
2610 allocated cell and grow heap when free list runs out. The scheme
2611 has been extended so that GC isn't triggered until all remaining
2612 cells are used. The implementation is also prepared for
2613 development in the direction of POSIX threads.
2615 * gc.c (SCM_EXPHEAP): In order to grow by a factor of 1.5,
2616 SCM_EXPHEAP should return half of the heap size.
2618 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2620 The following change to init.c is only enabled if Guile was
2621 configured with --enable-guile-debug.
2623 * init.c (scm_i_getenv_int): New function.
2624 (scm_boot_guile_1): Use the environment variables
2625 GUILE_INIT_HEAP_SIZE, GUILE_INIT_HEAP_SIZE2 to select heap size if
2626 they exist. (This may be replaced by a Scheme level mechanism in
2629 * objprop.c (s_scm_set_object_property_x): Use scm_assq instead of
2630 scm_assoc. (Thanks to Keisuke Nishida.)
2632 2000-03-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2634 * eval.c, lang.c, lang.h (scm_lisp_nil, scm_lisp_t): Renamed from
2635 scm_nil, scm_t. (Thanks to Keisuke Nishida.)
2637 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2639 * init.c (scm_boot_guile_1): Use same initial segment size for
2640 1-word and 2-word segments. Having the smaller size causes Guile
2641 to GC too often. Obviously something needs to be done to allow
2642 for a smaller 2-word segment without this to happen. (The amount
2643 of heap for each type should be automatically adapted to the
2644 application somehow.)
2646 [Almost all of these changes should be documented in the NEWS
2649 * gc.h (scm_freelist_t): New type.
2651 * pairs.h (SCM_NEWCELL, SCM_NEWCELL2): Use new style freelists.
2653 * gc.c (SCM_INIT_HEAP_SIZE): Changed from 32768 --> 40000 so that
2654 all of Guile basics fits into one segment and there suitable room
2656 (SCM_EXPHEAP): Now takes an argument. Grow by a factor of 1.5
2658 (scm_freelist, scm_freelist2): Now of type scm_freelist_t.
2659 Freelists now contains information about object span, cells
2660 collected and amount of cells in heap segments belonging to the
2662 (scm_heap_size, scm_gc_cells_collected): Removed.
2664 * init.c (scm_boot_guile_1): Make 2-word segment 8K (512 cells).
2666 * Makefile.am (libguile_la_LDFLAGS): Bumped library version
2669 * __scm.h eq.c, eval.c, gc.c, gc.h, gh_data, hash.c, numbers.c,
2670 numbers.h, objects.c, ramap.c, random.c, unif.c, unif.h: Extensive
2671 rewrite of handling of real and complex numbers.
2672 (SCM_FLOATS, SCM_SINGLES): These #ifdef conditionals have been
2673 removed along with the support for floats. (Float vectors are
2676 * tags.h (scm_tcs_bignums): Removed.
2677 (scm_tc16_bigpos, scm_tc16_bigneg): Replaced by scm_tc16_big.
2678 Use SCM_BIGSIGN(x) to test for sign!
2679 (scm_tc16_big): The new bignum type.
2680 (SCM_REAL_PART, SCM_IMAG_PART): Removed.
2682 * numbers.h (SCM_BIGSIGN): Sign moved to bit 16.
2683 (scm_makdbl): Deprecated.
2684 (SCM_NEWREAL, SCM_NEWCOMPLEX): New macros.
2685 (SCM_SINGP): Deprecated.
2687 (SCM_INEXP, SCM_CPLXP): Deprecated.
2688 (SCM_INEXACTP, SCM_COMPLEXP): New macros.
2689 (SCM_COMPLEX_REAL, SCM_COMPLEX_IMAG): Renamed from
2690 SCM_REAL, SCM_IMAG (and now only valid for complex numbers).
2691 (SCM_REAL, SCM_IMAG): New, *deprecated*, selectors which work both
2692 for doubles and complex numbers.
2693 (SCM_REAL_VALUE): New selector for doubles.
2694 (scm_double_t, scm_complex_t): New types.
2697 * numbers.c (scm_floprint, scm_floequal): Removed.
2698 (scm_print_real, scm_print_complex, scm_real_equalp,
2699 scm_complex_equalp): New functions.
2701 * unif.c (scm_makflo): Removed.
2703 * smob.h (SCM_SMOB_PREDICATE): New macro.
2704 (SCM_NEWSMOB2, SCM_RETURN_NEWSMOB2, SCM_NEWSMOB3,
2705 SCM_RETURN_NEWSMOB3): New macros.
2707 1999-11-21 Michael Livshin <mlivshin@bigfoot.com>
2709 The following changes implement primitive support for double cells
2710 (i.e. four-word cells) and change the representation of some
2711 things to multi-cells instead of cons+malloc. (Applied and
2714 * pairs.h (SCM_NEWCELL2): double-cell variants of SCM_NEWCELL.
2715 (SCM_CELL_WORD, SCM_CELL_WORDLOC, SCM_SET_CELL_WORD): primitive
2716 multi-cell access macros (used by the ones below).
2717 (SCM_CELL_WORD[0-3], SCM_SET_CELL_WORD[0-3]): multi-cell access
2720 * gc.c (scm_freelist2): multi-cell freelists.
2721 (inner_map_free_list): map_free_list, parameterized on ncells.
2722 "nn cells in segment mm" was misleading for ncells > 1; changed to
2723 "objects". still print cells too, though.
2724 (scm_map_free_list): rewritten using inner_map_free_list.
2725 (scm_check_freelist): get freelist as parameter, since now we have
2727 (scm_debug_newcell2): multi-cell variants of
2729 (scm_gc_for_newcell): take ncells and freelist pointer as
2731 (scm_gc_mark): add case for tc7_pws (procedures with setters are
2733 (scm_gc_sweep): don't free the float data, since it's not malloced
2735 (init_heap_seg): didn't understand what n_new_objects stood for,
2736 so changed to n_new_cells.
2737 (make_initial_segment): new function, makes an initial segment
2738 according to given ncells.
2739 (scm_init_storage): call make_initial_segment, for ncells={1,2,3}.
2741 * numbers.c (scm_makdbl): no malloc'ing needed, so the
2742 {DEFER,ALLOW}_INTS thing removed.
2744 * numbers.h (struct scm_dbl): changed to represent a double cell,
2745 with the number in the second half.
2747 * dynwind.c: changed the wind-guards representation to double
2750 * procs.c, procs.h: changed the procedure-with-setter representation
2753 * async.c, async.h: made async representation a double cell.
2755 * dynl.c: made dynamic_obj representation a double cell.
2757 2000-03-13 Gary Houston <ghouston@arglist.com>
2759 * ports.c (flush_void_port): renamed to flush_port_default.
2760 (end_input_void_port): renamed to end_input_default.
2762 * init.c (scm_standard_stream_to_port): create a void port instead
2763 of opening /dev/null if the standard file descriptors are bad.
2764 advantages: no portability problems, doesn't waste a file descriptor,
2765 simplifies the code (thanks to Marius for the idea).
2767 * vports.c (s_scm_make_soft_port): call scm_port_non_buffer.
2769 * void ports: make reading from a void port give EOF instead of
2771 * ports.c (s_scm_sys_make_void_port): modified docstring.
2772 (fill_input_void_port): new proc.
2773 (scm_init_ports): set up fill_input_void_port.
2774 * ports.c (scm_port_non_buffer): new proc.
2775 (scm_void_port): call scm_port_non_buffer.
2777 * fports.c (scm_setvbuf): docstring: remove the fcntl documentation
2778 which was incorrectly appended.
2780 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2782 * guile-doc-snarf.in: Don't use absolute path for `sed'. (Note
2783 that we can't use autoconf for this. Autoconf itself relies on
2784 the existence of `sed' somewhere on your path.) (Thanks to Dirk
2787 2000-03-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2789 * Makefile.am (libguile_la_SOURCES): Moved iselect.c here from
2790 EXTRA_libguile_la_SOURCES.
2792 * iselect.h: Always declare scm_internal_select.
2794 * iselect.c (scm_internal_select): Added SCM_ASYNC_TICK at the
2795 end. Also let scm_internal_select be a real function also when
2798 * __scm.h (SCM_TICK): Oops! Forgot to put SCM_ASYNC_TICK here...
2800 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2802 * __scm.h (SCM_ALLOW_INTS, SCM_REALLOW_INTS): Removed call to
2803 SCM_ASYNC_TICK. (This is a preparation for POSIX threads support,
2804 and kind of an experiment: Will this cause problems?)
2806 Sun Mar 12 13:26:30 2000 Greg J. Badros <gjb@cs.washington.edu>
2808 * Makefile.am: Added *.doc to DISTCLEANFILES.
2810 2000-03-12 Gary Houston <ghouston@arglist.com>
2812 * fports.c (scm_fdes_to_port): call fcntl F_GETFL to test that
2813 the fdes is valid before doing anything else. check that
2814 the file descriptor supports the modes required.
2815 (scm_fport_buffer_add): don't throw an error if fstat doesn't
2816 work: just use the default buffer size.
2818 * throw.c: change an outdated comment about scm_internal_catch
2819 BODY: it doesn't take a jumpbuf arg.
2821 * init.c (scm_standard_stream_to_port): install a handler in case
2822 scm_fdes_to_port throws an error. don't check here whether the
2823 file descriptor is valid, since scm_fdes_to_port will do that.
2824 set the revealed count depending on whether the port got the
2825 standard file descriptor.
2826 (stream_body_data): new type.
2827 (stream_body, stream_handler): new procs.
2829 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2831 * stacks.c, stacks.h, struct.c, tags.h, unif.c (scm_bits_t):
2832 Renamed from SCMWORD.
2834 * tags.h (SCM_NCELLP): Removed (SCMWORD).
2836 * arbiters.c (SCM_ARB_LOCKED): Use SCM_UNPACK_CAR.
2838 * async.c, boolean.h, debug.c, dynl.c, dynwind.c, eval.c, eval.h,
2839 feature.h, filesys.h, fluids.h, fports.c, fports.h, gc.c, gc.h,
2840 hash.c, keywords.h, macros.c, numbers.c, numbers.h, objects.c,
2841 objects.h, options.c, pairs.h, ports.c, ports.h, print.c,
2842 procs.h, ramap.c, read.c, smob.c, smob.h, srcprop.h, stacks.c,
2843 stacks.h, strports.c, struct.c, struct.h, tag.c, tags.h,
2844 throw.c, unif.c, unif.h, variable.h, vectors.h, weaks.c,
2845 weaks.h (SCM_PACK, SCM_UNPACK, SCM_UNPACK_CAR): Renamed from
2846 SCM_ASSCM, SCM_ASWORD, SCM_CARW).
2848 * numbers.h (SCM_SRS, SCM_INUM): Corrected SCM_ASSCM/ASWORD fixes.
2850 * alist.c, eval.c, net_db.c, posix.c, print.c, snarf.h, struct.c,
2851 tags.h: Fixed copyright notices.
2853 * struct.c, coop-threads.c: SCM_ASSCM/ASWORD fixes.
2855 2000-03-12 Marius Vollmer <mvo@zagadka.ping.de>
2857 * init.c (scm_standard_stream_to_port): Check whether the file
2858 descriptor is valid and substitute "/dev/null" when not.
2860 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2862 * coop-defs.h (struct timespec): Conditionally defined.
2864 * coop.c (coop_condition_variable_timed_wait_mutex): Use ETIMEDOUT
2867 * readline.c (match_paren): Bugfix: First arg to select is not
2868 number of descriptors but the number of the highest descriptor +
2871 This is a preliminary attempt at a cleanup of the threads support
2872 code. It moves things to better places, makes arguments more
2873 consistent with the POSIX API (which is used in GNOME's glib), and
2874 adds new functionality.
2876 * readline.c (scm_init_readline): Added new arg to scm_init_mutex.
2878 * coop-defs.h (scm_mutex_trylock): New macro: alias for
2880 (scm_cond_init): Changed definition to
2881 coop_new_condition_variable_init.
2883 * coop.c: #include <errno.h>
2884 (coop_timeout_qinsert): Moved here from iselect.c
2885 (coop_new_mutex_init, coop_new_condition_variable_init): New
2886 functions. The strange names are temporary. Use scm_mutex_init
2887 and scm_cond_init instead.
2888 (coop_mutex_trylock): New function. Uses errno.h:EBUSY. errno.h
2889 is ANSI C, but should we check for individual error codes in
2891 (coop_condition_variable_timed_wait_mutex): New function.
2892 (coop_key_create, coop_setspecific, coop_getspecific,
2893 coop_key_delete): New functions.
2895 * iselect.c (coop_timout_qinsert): Moved to coop.c
2897 2000-03-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2899 * pairs.h (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR,
2900 SCM_SETOR_CDR): Corrected SCM_ASSCM/WORD fixes.
2902 * tags.h (SCM_VOIDP_TEST): Renamed from VOIDP_TEST.
2905 * objects.h (SCM_CLASS_FLAGS, SCM_OBJ_CLASS_FLAGS,
2906 SCM_SET_CLASS_INSTANCE_SIZE), struct.h (SCM_STRUCT_VTABLE_DATA),
2907 proc.h (SCM_CLOSCAR): SCM_ASSCM/WORD fixes.
2909 * eval.c (scm_lookupcar1): Inserted SCM_ASWORD in expressions
2912 2000-03-11 Dale P. Smith <dpsm@en.com>, applied by Greg J. Badros, <gjb@cs.washington.edu>
2914 * numbers.c (scm_copy_big_dec, scm_copy_smaller, scm_big_ior,
2915 scm_big_xor, scm_big_and, scm_big_test): Added new lowlevel bignum
2916 logical functions from SCM.
2918 (logand, logior, logxor, logtest, logbit?): Extended scheme
2919 logical functions to use bignums from SCM.
2921 (lognot): Removed call to `SCM_VALIDATE_INUM' that prevented
2922 lognot from using bignums.
2924 Thu Mar 9 11:33:25 2000 Greg J. Badros <gjb@cs.washington.edu>
2926 * vectors.h (SCM_VELTS_AS_STACKITEMS): Added this macro to help in
2927 eliminating some warnings.
2929 * unif.c, strports.c, print.c, options.c: Fix some warnings on
2932 * gc.c, gc.h: Added scm_return_first_int(), and added comment re:
2933 what the scm_return_first* functions do.
2935 2000-03-09 Han-Wen Nienhuys <hanwen@cs.uu.nl>, applied by Greg J. Badros, <gjb@cs.washington.edu>
2937 * libguile/*.[ch]: make a distinction between SCM as a generic
2938 name for a Scheme object (now a void*), and SCM as 32 bit word for
2939 storing tags and immediates (now a long int). Introduced
2940 SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious
2941 code in the process: arbiter.c (use macros), unif.c (scm_array_p),
2943 Wed Mar 8 10:15:59 2000 Greg J. Badros <gjb@cs.washington.edu>
2945 * numbers.c: Use SCM_VALIDATE_LONG_COPY, and longs, not ints, in
2946 various logXXX primitives. Thanks Eric Moore!
2948 Tue Mar 7 08:05:22 2000 Greg J. Badros <gjb@cs.washington.edu>
2950 * run-test, remaining-docs-needed: Added these scripts. The
2951 second one is only temporary until the docstring additions are
2952 complete. run-test may best live on, but is here mostly for
2953 convenience and awareness for now.
2955 * hash.c: Docs, minor cleanup patch from Dirk Herrman.
2957 Thu Mar 2 16:06:58 2000 Greg J. Badros <gjb@cs.washington.edu>
2959 * error.h, error.c: Added `scm_wrong_type_arg_msg' to support
2960 displaying the expected type. Use SCM_LISTn in a couple places
2961 instead of scm_cons-ing by hand.
2963 * __scm.h: Added SCM_ASSERT_TYPE macro.
2965 * validate.h, scm_validate.h: Added the former, as a renamed
2966 version of the latter with SCM_ASSERT_TYPE used in
2967 SCM_MAKE_VALIDATE (instead of just SCM_ASSERT)
2969 * Makefile.am: Rename scm_validate.h to validate.h.
2971 * *.c, *.h: Include validate.h, not scm_validate.h (old name's
2972 prefix was superfluous).
2974 Thu Mar 2 15:33:12 2000 Greg J. Badros <gjb@cs.washington.edu>
2976 * hashtab.c: Improved documentation for lots of functions. Added
2977 handwritten docs for `hash-fold'.
2979 Thu Mar 2 15:13:25 2000 Greg J. Badros <gjb@cs.washington.edu>
2981 * list.c: Added hand-written docs for `del{q,v,ete}1!'.
2983 Thu Mar 2 12:38:30 2000 Greg J. Badros <gjb@cs.washington.edu>
2985 * list.c: Moved append docs to append! Thanks Dirk Hermann. Also,
2986 added append docs from R4RS.
2988 * strings.c: Docstring typo fix, + eliminate unneeded IMP tests.
2989 Thanks Dirk Hermann!
2991 * chars.h: Provide SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR and
2992 deprecate SCM_ICHRP, SCM_ICHR, SCM_MAKICHR. Thanks Dirk Hermann!
2994 * *.h, *.c: Use SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR throughout.
2995 Drop use of SCM_P for function prototypes... assume an ANSI C
2996 compiler. Thanks Dirk Hermann!
2998 Sat Feb 19 12:20:12 2000 Greg J. Badros <gjb@cs.washington.edu>
3000 * ports.c: Made `set-port-column!' and `set-port-line!' each
3001 return SCM_UNSPECIFIED instead of a (not-scheme-object) integer
3002 that caused a seg fault. Also fixed `set-port-column!'s
3003 docstring. Thanks Han-Wen Nienhuys for finding the bug!
3005 Sun Feb 13 19:11:42 2000 Greg J. Badros <gjb@cs.washington.edu>
3007 * arbiters.c, eq.c, gc.c, guardians.c, list.c, ports.c, print.c,
3008 regex-posix.c, scmsigs.c, stime.c, strings.c, variable.c, stime.c,
3009 strings.c, variable.c: Added lots of documentation, cleaned up
3010 some existing documentation. Occasionally changed formal params
3011 to match docs. Also folded an #ifdef into the inners of a
3012 primitive instead of having two copies of the primitive
3013 (`get-internal-real-time', from stime.c)
3015 Sun Feb 13 18:12:19 2000 Greg J. Badros <gjb@cs.washington.edu>
3017 * ports.c: Added docs for primitives missing them. Written by
3020 Sun Feb 13 09:40:36 2000 Greg J. Badros <gjb@cs.washington.edu>
3022 * guile-doc-snarf.in: Use ${AWK} -f guile-func-name-check, not
3023 just execing guile-func-name-check. Thanks Michael Livshin!
3025 Thu Feb 10 11:43:23 2000 Greg J. Badros <gjb@cs.washington.edu>
3027 * guile-snarf.awk.in: Tweak to work with Sun/HP awk, removed some
3028 dead code. Patch from Michael Livshin.
3030 * guile-doc-snarf.in: Tweak to work with Sun/HP sh. Patch from
3033 2000-02-09 Gary Houston <ghouston@arglist.com>
3035 * init.c (scm_init_standard_ports): when stdout is a tty, make the
3036 current-output-port unbuffered by default. this is less confusing
3037 for interactive use. it was line-buffered because of a
3038 performance problem with unbuffered ports, but I think it will be
3041 2000-02-08 Gary Houston <ghouston@arglist.com>
3043 * __scm.h: don't define long_long or ulong_long if HAVE_LONG_LONGS
3046 * stime.c (scm_localtime, scm_mktime): if neither HAVE_TM_ZONE nor
3047 HAVE_TZNAME are defined, use an empty string instead of giving two
3048 spurious compile-time errors.
3050 Tue Feb 8 13:57:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3052 * ports.c: Doc patches from Richard Kim. Pasted from MIT Scheme.
3055 Mon Feb 7 09:07:31 2000 Greg J. Badros <gjb@cs.washington.edu>
3057 * macros.c: Doc patches from Richard Kim. Pasted from scm.texi.

3061 * pairs.c: Doc patches from Richard Kim. Pasted from MIT Scheme
3062 (which is GNU GPL'd).
3064 2000-01-31 Gary Houston <ghouston@arglist.com>
3066 * strings.h: don't use SCM_P. don't include <string.h>.
3067 * error.c, gh_data.c, ports.c, script.c, strop.c: include <string.h>.
3069 * strings.c (scm_string_ref): make the 2nd argument compulsory.
3070 previously it defaulted to zero for no good reason that I can see.
3071 use a local variable for SCM_INUM (k). replace
3072 SCM_VALIDATE_INUM_DEF with SCM_VALIDATE_INUM_COPY.
3074 (scm_makfromstr): cosmetic changes.
3076 (scm_string): Accept only chars in the list, not strings, for
3077 conformance to R5RS (particularly for list->string, which is
3078 supposed to be the inverse of string->list.) remove
3079 SCM_DEFER_INTS/SCM_ALLOW_INTS, which is unnecessary since
3080 scm_makstr handles the cell allocation. when reporting wrong-type
3081 arg, don't report the position as 1.
3083 * posix.c (scm_init_posix): intern PIPE_BUF if it's defined.
3085 2000-01-29 Gary Houston <ghouston@arglist.com>
3087 * posix.c (scm_pipe): rewrote the docstring.
3089 * filesys.c (scm_select, retrieve_select_type, get_element,
3090 fill_select_type, set_element): modified so that Scheme
3091 "select" tests port buffers for the ability to provide input
3092 or accept output. Previously only the underlying file descriptors
3093 were checked. Rewrote the docstring.
3095 Thu Jan 27 10:14:25 2000 Greg J. Badros <gjb@cs.washington.edu>
3097 * vectors.c, symbols.c, strorder.c: Documentation cut and pasted
3098 from Gregg Reynolds. Thanks Gregg!
3100 Thu Jan 27 09:59:38 2000 Greg J. Badros <gjb@cs.washington.edu>
3102 * strop.c (scm_i_index): Obfuscated commented-out SCM_DEFINE by
3103 adding "x" prefix to the line so that guile-func-name-check
3104 doesn't complain unnecessarily.
3106 Wed Jan 26 17:33:52 2000 Greg J. Badros <gjb@cs.washington.edu>
3108 * throw.c: Factor out an #ifdef/#else/#endif choice more finely
3109 for maintainability.
3111 * strop.c: Documentation added by Gregg A. Reynolds. Pasted in
3114 Wed Jan 26 10:02:11 2000 Greg J. Badros <gjb@cs.washington.edu>
3116 * tag.c: Added doc for `tag', but mark as deprecated since Mikael
3117 suggests removing tag.c altogether (and using a new `class-of'
3120 * strings.c: Added documentation from Gregg A. Reynolds. Edited
3121 a bit by me to use FOO instead of @var{foo} and to have the
3122 summary come before preconditions on input. Also dropped trailing
3125 * gsubr.c: Do not use SCM_DEFINE for `gsubr-apply'. Register the
3126 function with scm_make_subr_opt w/ last arg of 0 so it is not
3127 visible at the Scheme level. Mikael says that this is the right
3128 thing because the first arg to the proc is the guts of a compiled
3129 closure and shouldn't be exposed to the Scheme level.
3131 Tue Jan 25 17:15:47 2000 Greg J. Badros <gjb@cs.washington.edu>
3133 * sort.c: typo in comment fixed.
3135 * keywords.c: Added documentation.
3137 * guardians.c: Added documentation (could be better).
3139 * gc.c: Added docs for gc-set-debug-check-freelist.
3141 * eq.c: Added docs for eq?, eqv? equal? abridged from R4RS.
3143 * boolean.c: Added docs for `not', `boolean?' (by hand).
3145 Tue Jan 25 13:28:56 2000 Greg J. Badros <gjb@cs.washington.edu>
3147 * random.c: Added documentation, from SLIB page:
3148 http://angela.ctrl-c.liu.se/~calle/scheme/slib_toc.html
3150 Mon Jan 24 17:50:20 2000 Greg J. Badros <gjb@cs.washington.edu>
3152 * variable.c, version.c: Added documentation, written by hand
3153 since I could not find anything already written that was
3156 2000-01-23 Gary Houston <ghouston@arglist.com>
3158 * filesys.c (scm_chown): omit port/fdes support if HAVE_FCHOWN is
3159 not defined (thanks to Richard Y. Kim).
3161 Thu Jan 20 13:00:38 2000 Greg J. Badros <gjb@cs.washington.edu>
3163 * Makefile.in: Removed, this is auto-generated.
3165 Thu Jan 20 11:33:47 2000 Dirk Hermann <dirk@ida.ing.tu-bs.de> --applied 01/20/00 gjb
3167 * list.c: Put some variable initialization code at the point of
3168 declaration; Added a comment for list*; Formatting changes.
3170 * load.c: use SCM_NNULLP to make sure the end of a list is not
3173 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3175 * backtrace.c (scm_display_error_message): Bugfix: Don't use
3176 result of scm_list_p as C boolean.
3177 (scm_display_error_message, scm_set_print_params_x): Use new
3178 validation macros. (Thanks to Dirk Herrmann.)
3180 * net_db.c (scm_resolv_error): Cast result from hstrerror.
3182 * strports.c (st_end_input): Inserted parenthesis to get operator
3185 * list.h (scm_init_list): Removed SCM_P around prototypes.
3187 * fports.c, list.c, numbers.c, ports.c, stime.c, symbols.c,
3188 filesys.c, posix.c: Converted docstrings to ANSI C format and
3189 escaped " occurring inside string literals.
3191 Tue Jan 18 13:21:08 2000 Mikael Djurfeldt <mdj@r11n07-s.pdc.kth.se>
3193 * posix.c (scm_mknod): Escape " occuring inside docstring.
3195 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3197 * alist.c, chars.c, debug.c, dynl.c, dynwind.c, error.c, eval.c,
3198 evalext.c, filesys.c, gc.c, hash.c, hashtab.c, ioext.c,
3199 keywords.c, list.c, load.c, macros.c, net_db.c, numbers.c,
3200 objprop.c, ports.c, posix.c, print.c, procprop.c, procs.c,
3201 ramap.c, regex-posix.c, root.c, scmsigs.c, simpos.c, socket.c,
3202 stacks.c, stime.c, strings.c, strop.c, strports.c, struct.c,
3203 symbols.c, throw.c, unif.c, vectors.c, version.c, vports.c,
3204 weaks.c: Converted docstrings to ANSI C format.
3206 * filesys.c (scm_chmod), simpos.c (scm_system), version
3207 (scm_version), vports (scm_make_soft_port): Escape " occuring
3210 Mon Jan 17 11:41:22 2000 Greg J. Badros <gjb@cs.washington.edu>
3212 * scm_validate.h: Added SCM_VALIDATE_ULONG_COPY,
3213 SCM_VALIDATE_LONG_COPY
3215 * numbers.c: Use SCM_VALIDATE_ULONG_COPY, instead of
3216 SCM_VALIDATE_INUM_COPY to let bigger numbers be used. Rename a
3217 couple of formal arguments (and fix their uses) to make arguments
3218 match the documentation.
3220 2000-01-14 <mstachow@alum.mit.edu>
3222 * Makefile.am: Augment path when running guile-doc-snarf so
3223 guile-func-name-check is found.
3225 Fri Jan 14 09:34:55 2000 Greg J. Badros <gjb@cs.washington.edu>
3227 * scm_validate.h (SCM_NUM2LONG_DEF): Fix this macro to just use
3228 def, not SCM_MAKINUM(def); thanks Janis Bzerins!
3230 Wed Jan 12 00:06:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3232 * net_db.c (s_scm_inet_makeaddr): Use SCM_NUM2ULONG since that's
3233 the way guile-1.3.4 worked, but #if 0 out the version using
3234 SCM_VALIDATE_INUM_COPY for stricter testing.
3236 Tue Jan 11 18:24:18 2000 Greg J. Badros <gjb@cs.washington.edu>
3238 * guile-doc-snarf.in: Use new $fullfilename for running
3239 guile-func-name-check, and put "$fullfilename" and "$filename" in
3240 quotes at uses to make sure re-splitting on whitespace does not
3241 occur (so filenames w/ embedded whitespace would work okay, though
3242 I sure hope we never have to deal with that! :-) ). Thanks to
3243 Mikael for pointing out the source_dir != build_dir was broken.
3245 Tue Jan 11 17:42:40 2000 Greg J. Badros <gjb@cs.washington.edu>
3247 * scm_validate.h: Added SCM_NUM2LONG_DEF macro. Make
3248 SCM_OUT_OF_RANGE use SCM_MAKINUM, not scm_long2num. Added
3249 SCM_COERCE_ROSTRING macro. Added SCM_VALIDATE_NONEMPTYLIST
3250 macro. Fix SCM_VALIDATE_STRINGORSUBSTR macro to not use SLOPPY
3253 * ports.c (scm_port_closed_p): Validate that the arg is a PORT,
3254 then return whether it's an open port (was validating that it was
3255 an open port -- this was a bug I introduced back in December, but
3256 my careful reading of diffs caught it).
3258 * numbers.c: Recombine the two conditional-compilation paths for
3259 all the log* primitives -- they were split based on #ifndef
3260 scm_long2num; factored out a SCM_LOGOP_RETURN macro, and fixed
3261 some bugs and inconsistencies in the two sets of implementations.
3262 (scm_lognot) Fixed *atrocious* re-use of a SCM as an integer!
3264 * ioext.c: Use SCM_ASSERT_RANGE in a couple places, and
3265 SCM_VALIDATE_INUM_COPY once where it should've been used.
3267 * fluids.c (scm_internal_with_fluids): Use
3268 SCM_VALIDATE_LIST_COPYLEN.
3270 * filesys.c: Use SCM_NUM2LONG instead of SCM_VALIDATE_INUM_COPY;
3271 this is questionable as it relaxes type safety, but other changes
3272 were useful and all SCM_NUM2LONG's should probably be
3273 revisited. Use SCM_OUT_OF_RANGE, SCM_WRONG_TYPE_ARG.
3275 * evalext.c: line-break change on 1 line.
3277 * eval.c (nconc2last): Takes a non-empty list as its first
3278 argument, not just a list.
3280 * dynl.c: Use new SCM_COERCE_ROSTRING macro.
3282 Tue Jan 11 15:44:23 2000 Greg J. Badros <gjb@cs.washington.edu>
3284 * dynl.c, feature.c, filesys.c, fports.c, list.c, load.c,
3285 net_db.c, sort.c, stacks.c, unif.c: Use SCM_WTA, SCM_MISC_ERROR
3288 * symbols.c (scm_sysintern0): Fixed the function name in a
3289 scm_misc_error invocation.
3291 * print.c (scm_simple_format): Do not need SCM_COERCE_SUBSTR, and
3292 use scm_return_first to ward off latent GC bug that Mikael caught.
3294 * async.c: Use SCM_VALIDATE_ASYNC_COPY one place where it wasn't
3295 used before but should've been.
3297 2000-01-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3299 * snarf.h (SCM_PROC1): Replaced SCM (*) (...) with
3300 SCM_FUNC_CAST_ARBITRARY_ARGS.
3302 Tue Jan 11 13:44:07 2000 Greg J. Badros <gjb@cs.washington.edu>
3304 * guile-func-name-check.in: Added this script to statically check
3305 #define FUNC_NAME, #undef FUNC_NAME in the source.
3307 * sort.c, posix.c: Fix #undef FUNC_NAME lines to not have trailing
3308 redundant comment, semicolon; caught by new guile-func-name-check
3311 * debug.c: Fix mistaken #define FUNC_NAME for scm_make_iloc.
3312 Caught by new guile-func-name-check-script.
3314 * Makefile.am: Added guile-func-name-check to bin_SCRIPTS
3316 * ramap.c: Fix #if 0'd out code to be syntactically acceptable to
3317 guile-func-name-check.
3319 * guile-doc-snarf.in: Run guile-func-name-check on the file before
3322 Tue Jan 11 11:31:10 2000 Greg J. Badros <gjb@cs.washington.edu>
3324 * fports.c, ports.c, ports.h, strports.c, vports.c: Make write
3325 port function take const void*, not void*.
3327 Tue Jan 11 11:18:07 2000 Greg J. Badros <gjb@cs.washington.edu>
3329 * scm_validate.h, chars.c, ports.c, print.c, read.c, strings.c,
3330 strop.c: Use SCM_VALIDATE_ICHR, SCM_VALIDATE_ICHR_COPY instead of
3331 SCM_VALIDATE_CHAR, SCM_VALIDATE_CHAR_COPY. Change made for
3332 consistency with the other macros dealing with immediate
3333 characters. (Similar to INT -> INUM change a week or so ago).
3335 Tue Jan 11 10:41:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3337 * dynl.c, error.c, eval.c, feature.c, filesys.c, fports.c, list.c, load.c,
3338 net_db.c, read.c, socket.c: Update error messages to use ~A for
3339 %s, ~S for %S to work with new `simple-format' format and be
3340 standardized better.
3342 * print.h, print.c (scm_simple_format): Added `simple-format'
3343 primitive. It's the old scm_display_error, with ARGS now a rest
3344 parameter, and the destination first instead of last (and a couple
3345 new capabilities inspired by `format' -- #t as destination means
3346 current-output-port, #f means return the formatted text as a
3349 * gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
3351 * backtrace.c (scm_display_error_message): Rewrote to use
3352 scm_simple_format() procedure.
3354 * __scm.h: Added commented-out #define of GUILE_DEBUG_FREELIST
3356 2000-01-09 Marius Vollmer <mvo@zagadka.ping.de>
3358 Finally applied the libltdl patch from Thomas Tanner, with slight
3361 * DYNAMIC-LINKING: Removed because it is obsolete.
3362 * dynl.c: Use ANSI prototypes.
3363 (sysdep_dynl_link): Use lt_dlopenext instead of lt_dlopen.
3364 * scmconfig.h.in: Do not change, as it is automatically generated.
3366 1999-07-25 Thomas Tanner <tanner@ffii.org>
3368 * dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c: deleted
3370 * Makefile.am: likewise, add INCLTDL (libltdl headers) to
3371 INCLUDES, set dlpreopened files in LDFLAGS, link libguile
3373 * dynl.c: use libltdl if DYNAMIC_LINKING is enabled,
3374 * guile.c: register preloaded modules
3375 * scmconfig.h.in: remove obsolete symbols
3377 2000-01-09 Gary Houston <ghouston@arglist.com>
3379 * These changes should make it unnecessary to call tzset from
3380 Scheme after modifying the TZ environment variable, even if the
3381 system date facilities cache the value.
3382 * stime.c (setzone, scm_localtime): added comments.
3383 (tzset): don't define a noop tzset macro if HAVE_TZSET not defined.
3384 (setzone): don't call tzset.
3385 (restorezone): call tzset only if HAVE_TZSET is defined.
3386 (scm_tzset): don't define if HAVE_TZSET not defined. Change the
3387 doc string to indicate that this procedure isn't likely to do
3389 (scm_localtime, scm_strftime, scm_mktime): call tzset if
3390 LOCALTIME_CACHE is defined.
3392 2000-01-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3394 * posix.c (scm_sync): Return SCM_UNSPECIFIED.
3396 2000-01-09 Gary Houston <ghouston@arglist.com>
3398 * eval.c: define scm_unbound_variable_key ('unbound-variable).
3399 scm_lookupcar1: throw an error with key 'unbound-variable instead
3400 of 'misc-error when an unbound variable is encountered.
3402 * filesys.c (scm_mkdir, scm_rmdir, scm_getcwd, scm_select,
3403 scm_symlink, scm_readlink, scm_lstat),
3404 posix.c (scm_setpgid, scm_setsid, scm_ctermid, scm_tcgetpgrp,
3405 scm_tcsetpgrp, scm_uname, scm_setlocale, scm_mknod, scm_nice,
3407 simpos.c (scm_system),
3408 stime.c (scm_times, scm_strptime):
3409 move the HAVE_XXX feature tests out of the procedure bodies.
3410 don't use SCM_SYSMISSING.
3411 scm_validate.h (SCM_SYSMISSING): removed.
3412 error.h, error.c (scm_sysmissing): comment that this is deprecated.
3413 see ChangeLog entry for 1999-12-28.
3415 Sat Jan 8 19:52:04 2000 Greg J. Badros <gjb@cs.washington.edu>
3417 * scm_validate.h (SCM_VALIDATE_BOOL_COPY): Fix typo.
3419 Sat Jan 8 17:06:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3421 * backtrace.c: Fix spelling typo in a comment.
3423 * snarf.h: Use new SCM_DOCS macro to encapsulate the non SCM_INIT
3424 text. Reformatted some of the expansions.
3426 Fri Jan 7 15:50:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3428 * scm_validate.h (SCM_OUT_OF_RANGE): Use scm_out_of_range_pos to
3429 report the position of the argument.
3431 * error.h, error.c (scm_out_of_range_pos): Added this function to
3432 take extra "pos" argument, the position number of the errant
3435 * debug.c: Use SCM_OUT_OF_RANGE instead of scm_out_of_range.
3437 * snarf.h: Use SCM_HERE and SCM_INIT as names, not SCM_NOTSNARF
3438 and SCM_SNARFING. Also put the %%% in the SCM_INIT since Mikael
3439 prefers that and I'm reasonably indifferent.
3441 Fri Jan 7 15:03:32 2000 Greg J. Badros <gjb@cs.washington.edu>
3443 * snarf.h: Factor out differences between C++ and non-C++ into
3444 SCM_FUNC_CAST_ARBITRARY_ARGS macro. Modify all the snarf macro
3445 definitions to use SCM_NOTSNARF and SCM_SNARFING macros (like
3446 Mikael's macros, below, but changed names and SCM_SNARFING no
3447 longer expands to include %%% -- that must appear in the argument
3448 so that the token appears at the call-site as a reminder).
3450 2000-01-07 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3452 * snarf.h (SCM_INSITU, SCM_INIT): New snarf macros for use in user
3453 snarf macro definitions.
3455 2000-01-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3457 * chars.c (scm_integer_to_char): Use Greg's nice
3458 SCM_VALIDATE_INUM_RANGE macro for argument checking for closer
3461 Thu Jan 6 11:48:49 2000 Greg J. Badros <gjb@cs.washington.edu>
3463 * *.c, snarf.h: Replace GUILE_PROC1 with SCM_DEFINE1 throughout.
3465 Thu Jan 6 11:22:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3467 * Makefile.am (ETAGS_ARGS): Switch to SCM_DEFINE, SCM_DEFINE1
3468 instead of GUILE_PROC.
3470 Thu Jan 6 11:21:49 2000 Greg J. Badros <gjb@cs.washington.edu>
3472 * alist.c: Do not report mismatch errors on some uses of `tmp' (do
3473 this by using SCM_ARG2 instead of `2' in the SCM_VALIDATE_CONS
3476 Thu Jan 6 09:54:33 2000 Dirk Herrmann <dirk@ida.ing.tu-bs.de> --gjb applied
3478 * scm_validate.h: Remove some redundant NIMP tests.
3480 * alist.c: minimize scope of the tmp variables, and initialize
3481 them when declared. The strange SCM_NIMP tests are replaced by
3482 SCM_CONSP tests that more closely reflect the intended semantics.
3483 However, we don't get a performance penalty here, because the
3484 SCM_CONSP test was performed by the ALISTCELL test anyway. * The
3485 extremely ugly use of ASRTGO macros was removed: The calls to
3486 ASRTGO were not encapsulated by "#ifndef SCM_RECKLESS", but got a
3487 label parameter that only exists when SCM_RECKLESS is not defined.
3488 This works, because ASRTGO itself is defined in a way that it only
3489 makes use of the label parameter if SCM_RECKLESS is not defined
3490 (shudder!). Does guile make at all use of the possibility to
3491 define SCM_RECKLESS? * Codesize is likely to be reduced, since
3492 instead of two calls to SCM_ASSERT performed by the ALISTCELL test
3493 we now only get one test.
3495 * list.c: Use SCM_NNULLP, not SCM_NIMP as appropriate. Also use
3496 SCM_NULLP instead of SCM_IMP. Drop use of "register" keyword on
3497 some variables in `list?'. Fix `reverse' and `reverse!'
3498 primitives to handle improper lists better.
3500 Wed Jan 5 11:24:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3502 * *.[ch]: Whitespace changes -- added space after SCM_VALIDATE_*
3503 macros and SCM_DEFINE macros to match GNU coding standards.
3505 Wed Jan 5 11:04:24 2000 Greg J. Badros <gjb@cs.washington.edu>
3507 * *.[ch]: Replace GUILE_PROC w/ SCM_DEFINE.
3509 Wed Jan 5 10:59:06 2000 Greg J. Badros <gjb@cs.washington.edu>
3511 * *.[ch]: Replace SCM_VALIDATE_INT w/ SCM_VALIDATE_INUM for
3512 better consistency with the names of other SCM_VALIDATE_ macros
3513 and better conformance to guile naming policy.
3515 Wed Jan 5 10:50:39 2000 Greg J. Badros <gjb@cs.washington.edu>
3517 * ports.c (s_scm_close_all_ports_except): Use SCM_ARG1 in a
3518 SCM_VALIDATE instead of 1 to avoid a check on the argument (since
3519 it's not the actual name of the formal).
3521 * guile-snarf.awk.in: Do argument/number mismatch checking and
3522 print warnings in an Emacs compile-mode parseable format.
3524 * struct.c: Use SCM_ASSERT_RANGE instead of SCM_ASSERT w/
3525 SCM_OUTOFRANGE as 3rd argument.
3527 * random.c: Fix argument/number mismatch (that I introduced :-( ).
3529 * __scm.h: Do not #define SCM_ARG* when snarfing;
3530 lets us distinguish between 1 and SCM_ARG1 when snarfing as only
3531 the former (using the number) requires the argument to match the
3532 formal in the current argument snarfing check.
3534 * snarf.h: Give new definition of SCM_ASSERT when in
3535 snarfing mode to output a lexically-identifiable sequence that the
3536 guile-snarf.awk script uses to verify argument/position matching.
3538 * ramap.c: Remove extraneous #undef FUNC_NAME.
3540 Wed Jan 5 08:36:38 2000 Greg J. Badros <gjb@cs.washington.edu>
3542 * guile-doc-snarf.awk.in: Removed -- guile-snarf.awk.in is the
