21 texinfo markup and remove trailing newlines.
23 2000-08-17 Michael Livshin <mlivshin@bigfoot.com>
25 this changes the Guile GC to use cards (aka "chunklets").
26 (most of the ideas and some of the code are by Greg Harvey, though
27 the code is probably unrecognizable now. the original chunklet
28 proposal, way back, is by Dale Jordan).
30 * tags.h: (SCM_GCTYPE16, SCM_GCCDR, SCM_GC[8]MARKP,
31 SCM_SETGC[8]MARK, SCM_CLRGC[8]MARK): moved from here into gc.h.
32 some (most) of these are probably going to be deprecated.
34 * gc.h (SCM_MARKEDP): simplified, there are no different mark bit
36 (SCM_GC_CARD_*, SCM_C_BVEC_*): lots of new macros to deal with
37 cards and bvecs (bit-vectors).
39 * gc.c: (scm_default_init_heap_size_*): defined to take cards into
40 account, but keeping more or less the same values as previously.
41 added some simple helper macros.
42 (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK): defined to take cards
44 (BVEC_*, scm_mark_space_t, current_mark_space, mark_space_ptr,
45 current_mark_space_offset, mark_space_head, get_bvec,
46 clear_mark_space): new functions and supporting variables, types
47 and macros that implement mark space management.
48 (scm_igc): clear the mark space (all of it) before beginning the
50 (scm_gc_mark): changed the tests for rogue cells, much simplified
51 throughout (no different mark bit locations to worry about now).
52 (scm_mark_locations): don't consider card header cells.
54 (scm_gc_sweep): simplified.
55 (init_heap_seg): changed to take cards into account.
57 2000-08-16 Michael Livshin <mlivshin@bigfoot.com>
59 * stime.c (scm_c_get_internal_run_time): new function, same as
60 scm_get_internal_run_time but returns a long. it's used by the GC
61 for timekeeping, since with scm_get_internal_run_time there is a
62 (extremely theoretical) possibility of consing.
63 (scm_get_internal_run_time): redefined in terms of
64 scm_c_get_internal_run_time.
66 * stime.h: added prototype for scm_c_get_internal_run_time.
68 * gc.c (scm_gc_stats): add more obscure stats, such as: mark time,
69 sweep time, total marked cells, total swept cells, and number of
71 (gc_start_stats): renamed from scm_gc_start, made static, taught
72 to init the new stats.
73 (gc_end_stats): renamed from scm_gc_end, made static, taught to
74 calculate the new stats.
75 (scm_igc): don't call gc_start_stats unless we are sure that we
76 are indeed going to collect. also, added some timekeeping between
77 the mark and sweep phases.
78 (scm_gc_sweep): count number of cells we sweep as we go.
80 * gc.h: removed prototypes for scm_gc_{start,end}.
82 2000-08-13 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
84 * alist.c (scm_assq, scm_assv, scm_assoc): Report argument type
85 error for the alist rather than the sublist where the type
86 mismatch is discovered.
88 2000-08-13 Neil Jerram <neil@ossau.uklinux.net>
90 * root.c (s_scm_call_with_dynamic_root): Docstring fix - rogue

117 reference manual doc on keywords.
119 * error.c (scm_error_scm): Fix texinfo syntax error in
120 docstring. (@code(~S) should be @code{~S}.)
122 * dynl.c: Remove surplus newlines from end of docstrings.
124 2000-08-11 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
126 * eval.c (scm_eval): Backward incompatible change: Now takes an
127 environment specifier as second arg. `eval' hereby becomes R5RS
129 (scm_i_eval_x, scm_i_eval): New functions (replace
131 (scm_eval2, scm_eval_3): Deprecated.
132 (scm_top_level_lookup_closure_var): Deprecated.

155 scm_interaction_environment ().
157 * script.c (scm_shell): Pass scm_the_root_module () as second arg
160 * load.c (load): Use `scm_selected_module' to compute second arg
161 to new scm_i_eval_x; Don't call it if module system hasn't booted.
162 (scm_read_and_eval_x): Deprecated.
163 #include "modules.h".
165 * debug.c (scm_local_eval): Use scm_i_eval and scm_i_eval_x.
166 (scm_start_stack): Use scm_i_eval.
168 * strports.c: #include "modules.h".
170 * print.c (scm_simple_format): Be case-insensitive for ~A and ~S
173 2000-08-09 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
175 The following changes are intended to ensure that struct instances
176 are freed before their vtables. It's optimized for the most
177 common case, which is freeing of struct instances.
179 * gc.c (scm_gc_mark, scm_gc_sweep): Remove vcell = 1 magic.
180 (scm_structs_to_free): New variable.
181 (scm_gc_sweep): Hook up structs to free on the scm_structs_to_free
184 * struct.h (SCM_STRUCT_GC_CHAIN, SCM_SET_STRUCT_GC_CHAIN): New
186 (scm_structs_to_free, scm_struct_prehistory): Declare.
188 * struct.c (scm_make_struct, scm_make_vtable_vtable): Structs
189 handles are now double cells; Initialize SCM_STRUCT_GC_CHAIN to
191 (scm_struct_gc_init, scm_free_structs): New GC C hooks.
192 (scm_struct_prehistory): Install them.
194 * init.c (scm_boot_guile_1): Call scm_struct_prehistory.
196 2000-08-06 Marius Vollmer <mvo@zagadka.ping.de>
198 * read.c (scm_flush_ws): Include filename in error message when it
201 2000-08-05 Marius Vollmer <mvo@zagadka.ping.de>
203 * iselect.c: Include <unistd.h>. Thanks to Bertrand Petit!
205 2000-08-02 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
207 * struct.c (scm_make_struct_layout, scm_make_struct,
208 scm_make_vtable_vtable): Updated documentation.
210 * print.c (scm_simple_format): Bugfix: Coerce port before using
213 2000-07-31 Gary Houston <ghouston@arglist.com>
215 * net_db.c: declare h_errno only if HAVE_H_ERRNO is not defined
216 (thanks to Richard Kim for the bug report).
218 2000-07-30 Marius Vollmer <mvo@zagadka.ping.de>
220 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
221 scm_assoc_remove_x): Use scm_delq1_x instead of scm_delq_x, since
222 using the latter is pointless.
224 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
226 * gc.c (scm_gc_sweep): Renamed local variable from 'free' to
227 'free_struct_data' to avoid confusion with stdlib's 'free'.
229 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
231 * vectors.c (scm_make_vector): Fix the initialization order of
232 the vector such that the type cell is initialized last.
234 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
236 * struct.[ch] (scm_struct_init): Made static. Fixed not to rely
237 on the struct cell to be fully initialized.
239 * struct.c (scm_make_struct, scm_make_vtable_vtable): Fix the
240 initialization order of the struct such that the type cell is
243 2000-07-25 Marius Vollmer <mvo@zagadka.ping.de>
245 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
246 scm_assoc_remove_x): Remove only the first cell with a matching
249 2000-07-24 Marius Vollmer <mvo@zagadka.ping.de>
251 * stime.c (scm_strftime): Recognize a return value of zero from
252 strftime as buffer overflow and take care to detect a valid zero
253 length result regardless. Thanks to David Barts!
255 2000-07-23 Marius Vollmer <mvo@zagadka.ping.de>
257 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
258 scm_assoc_remove_x): Remove all cells whose key is eq, eqv, or
259 equal (respectively) to the argument key, not all cells that are
260 eq, eqv, or equal to the first cell with the argument key. Thanks
263 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
265 * gc.h (SCM_FREE_CELL_CDR, SCM_SET_FREE_CELL_CDR), hooks.c
266 (make_hook), modules.c (OBARRAY, USES, BINDER): Pack and unpack
267 SCM values appropriately.
269 * modules.c (scm_standard_eval_closure): Don't pass an inum to
270 scm_makcclo, but rather a long value.
272 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
274 read.c (scm_lreadrecparen), srcprop.c (scm_set_source_property_x):
275 SCM_SETCDR and SCM_WHASHSET macros don't deliver a return value.
276 Thanks to Han-Wen Nienhuys for the bug report.
278 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
280 * root.[ch] (scm_call_catching_errors): Deprecated.
282 * root.c (scm_init_root): Initialize the root smob type using the
283 standard initialization functions.
285 2000-07-17 Marius Vollmer <mvo@zagadka.ping.de>
287 * eval.c (unmemocopy): Don't rely on V being a list of at least
288 one element. Thanks to Bill Schottstaedt!
290 2000-07-15 Michael Livshin <mlivshin@bigfoot.com>
292 * gc.c (scm_done_free): new.
293 expanded comments about scm_done_malloc.
295 * gc.h: added prototype for scm_done_free
297 2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
299 * gc.h (scm_take_stdin): Removed.
301 * gc.h (SCM_VALIDATE_CELL): Delegate cell checks to function
302 scm_assert_cell_valid to allow extensions to the checking
303 functionality without need to recompile everything.
305 * gc.[ch] (scm_assert_cell_valid, scm_set_debug_cell_accesses_x):
306 Added as conditionally compiled functions for the case that
307 SCM_DEBUG_CELL_ACCESSES is enabled.
309 * gc.c (debug_cells_p): Added to indicate whether compile-time
310 included cell access debugging is run-time enabled.
312 * gc.[ch] (scm_gc_running_p): Added to indicate that scm_igc is
313 being executed. Intended to be used instead of scm_gc_heap_lock
316 * error.c (scm_error), gdbint.c (SCM_GC_P): Use scm_gc_running_p
317 instead of scm_gc_heap_lock.
319 * gc.c (scm_igc): Set scm_gc_running_p to true while running.
321 * gc.c (scm_mark_locations): Don't mark free cells.
323 * weaks.c (scm_scan_weak_vectors): Use SCM_FREE_CELL_P instead of
326 2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
328 * gc.c (scm_mark_locations): Minimized some variable scopes and
329 simplified the code a bit.
331 2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
333 * gc.h (SCM_SET_FREE_CELL_TYPE, SCM_SET_FREE_CELL_CDR,
334 SCM_FREE_CELL_P, SCM_FREE_CELL_CDR): Added since free cells
335 should not be accessed via SCM_C[AD]R. Further, using dedicated
336 macros to access free cells allows all other cell accessing macros
337 to treat acesses to free cells as errors, thus enabling better
338 error checks for cell accesses. SCM_FREE_CELL_P is supposed to
339 replace SCM_FREEP some time.
341 * gc.h (SCM_NEWCELL, SCM_NEWCELL2), gc.c (map_free_list,
342 free_list_length, scm_check_freelist, scm_debug_newcell,
343 scm_debug_newcell2, freelist_length, scm_gc_for_newcell,
344 scm_gc_mark, scm_gc_sweep, init_heap_seg): Only use the dedicated
345 cell accessors when accessing free cells.
347 2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
349 * gc.h (SCM_CELL_WORD, SCM_CELL_OBJECT): Treat the referenced
350 object as const in order to make the compiler warn about code like
351 SCM_CELL_WORD (x, n) = y. Instead, SCM_SET_CELL_WORD (x, n, y)
354 (SCM_CELL_WORD_LOC, SCM_CARLOC, SCM_CDRLOC): Return the address
355 as an address to a non-const object, since these macros are used
356 to allow direct write access to objects.
358 2000-07-07 Dirk Herrmann <D.Herrmann@tu-bs.de>
360 * hashtab.c (scm_hash_fn_create_handle_x): Signal an error if the
361 given hash table has no slots.
363 2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
365 * gc.c (policy_on_error): Added in order to allow alloc_some_heap
366 to react to malloc failures in a context dependent way.
368 (scm_check_freelist): No need to flush streams before abort().
370 (scm_gc_for_newcell): Try to allocate new memory in three phases:
371 grow heap if preferred, if still no memory available collect
372 garbage, if still no memory available grow heap.
374 (heap_segment_table_size): Added to always reflect the actual
375 size of the heap segment table, because scm_n_heap_segs may differ
376 from the heap segment table size.
378 (alloc_some_heap): In case of malloc failure, react according to
379 the new policy_on_error parameter (either return to caller or
380 abort immediately). Further, keep heap_segment_table_size up to
383 (scm_init_storage): Initialize heap_segment_table_size.
385 2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
387 * gh.h: Don't include <stdio.h>. Thanks to Han-Wen Nienhuys for
390 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
392 * __scm.h (SCM_OUTOFRANGE, SCM_NALLOC, SCM_HUP_SIGNAL,
393 SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL, SCM_SEGV_SIGNAL,
394 SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL, SCM_SIG_ORD,
395 SCM_ORD_SIG, SCM_NUM_SIGS): Re-introduce these as deprecated
398 * error.c (scm_wta): Re-introduce dispatching for SCM_OUTOFRANGE
399 and SCM_NALLOC, but as a deprecated feature.
401 2000-06-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
403 * debug.c: Added #include fluids.h.
405 * numbers.c (scm_gr_p, scm_leq_p, scm_geq_p): Turned into
406 primitive generics. (Thanks to Nicolas Neuss.)
408 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
410 * gc.c (alloc_some_heap): Use scm_memory_error to indicate a
411 failed attempt to get additional memory from the system.
413 (scm_gc_for_newcell): Changed the control structure to make the
414 behaviour explicit for the case that gc is not able to free any
417 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
419 * __scm.h (SCM_OUTOFRANGE): Removed.
421 * error.c (scm_wta): Removed sick dispatch code for range
422 errors. (More sick dispatches still to be removed.)
424 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
425 scm_hash_fn_remove_x): Eliminate redundant test for if unsigned
426 value is non-negative. Use scm_out_of_range to signal range
429 * hooks.c (make_hook), unif.c (scm_aind): Use scm_out_of_range to
432 * list.c (scm_list_ref, scm_list_set_x, scm_list_cdr_set_x): Fix
433 error reporting (now uses original input parameter to report wrong
434 type argument errors). Use SCM_OUT_OF_RANGE to report range
435 errors and SCM_WRONG_TYPE_ARG to report type errors.
437 * strings.c (scm_substring): Make range checks for negative
438 values explicit (former behaviour relied on an implicit
439 conversion from signed to unsigned). Don't use SCM_ASSERT for
442 * unif.c (scm_aind, scm_transpose_array, scm_bit_set_star_x,
443 scm_bit_count_star): Use scm_out_of_range to signal range
446 * unif.c (scm_transpose_array, scm_bit_position), vectors.c
447 (scm_vector_ref, scm_vector_set_x, scm_vector_move_left_x,
448 scm_vector_move_right_x): Use SCM_ASSERT_RANGE to check ranges.
450 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
452 * validate.h (SCM_VALIDATE_INUM_MIN_COPY,
453 SCM_VALIDATE_INUM_MIN_DEF_COPY, SCM_VALIDATE_INUM_RANGE_COPY):
454 Perform all range checks based on the input value. The former way
455 of using the value that is assigned to the target variable fails
456 if the assignment to the target variable itself can change the
457 value because of type conversion.
459 (SCM_ASSERT_RANGE): Use scm_out_of_range to signal range errors.
461 2000-06-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
463 * gc.c (scm_gc_for_newcell): Behave gracefully also if scm_igc
464 doesn't yield any new cells. In theory this could happen if all
465 cells allocated with NEWCELL are either in use or conservatively
466 marked and all cluster spine cells are conservatively marked.
469 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
471 * __scm.h (SCM_NALLOC): Removed.
473 * error.c (scm_wta): Removed sick dispatch code for memory
474 errors. (More sick dispatches still to be removed.)
476 * numbers.c (scm_mkbig, scm_adjbig), ports.c (scm_make_port_type),
477 random.c (scm_i_copy_rstate, scm_c_make_rstate), smob.c
478 (scm_make_smob_type), srcprop.c (scm_make_srcprops), vectors.c
479 (scm_vector_set_length_x): Now using scm_memory_error to signal
482 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
484 * __scm.h: Removed some commented code and fixed some comments.
486 (SCM_HUP_SIGNAL, SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL,
487 SCM_SEGV_SIGNAL, SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL,
488 SCM_SIG_ORD, SCM_ORD_SIG, SCM_NUM_SIGS): Removed.
490 * async.c: Removed some commented code.
492 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
494 * gc.c (scm_gc_mark, scm_gc_sweep, scm_must_malloc,
495 scm_must_realloc, scm_must_free, alloc_some_heap): Use the
496 appropriate error signalling function.
498 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
500 * root.h (scm_first_type): Removed.
502 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
504 * gc.c (MIN_GC_YIELD): Removed.
506 2000-06-28 Michael Livshin <mlivshin@bigfoot.com>
508 * gc.c (scm_gc_for_newcell): don't try to do GC if it's blocked,
511 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
513 * async.c (scm_gc_async, scm_gc_vcell, scm_sys_gc_async_thunk):
516 (scm_init_async): Moved initialization for scm_gc_async and
517 scm_gc_vcell to gc.c. Moved initialization of scm_asyncs here
520 * async.h (scm_gc_async): Not globally visible any more.
522 * gc.c (scm_gc_stats): Made callable even from within regions
525 (scm_gc_end): Eliminate the hardcoding of the marking of the
526 scm_gc_async from the gc core.
528 (scm_init_storage): Don't initialize the scm_asyncs list here.
529 This is now done in asyncs.c.
531 (scm_gc_vcell): Moved here from async.c.
533 (gc_async): Renamed from scm_gc_async, moved here from async.c
536 (gc_async_thunk): Renamed from scm_sys_gc_async_thunk and moved
539 (mark_gc_async): New hook function for scm_after_gc_c_hook.
541 (scm_init_gc): Added initialization of scm_gc_vcell and
542 gc_async. Further, add mark_gc_async to scm_after_gc_c_hook.
544 * init.c (scm_boot_guile_1): scm_init_gc requires asyncs to be
547 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
549 * gc.c (scm_igc): Removed commented code that once was intended
550 to unprotect struct types with no instances.
552 * root.h (scm_type_obj_list): Removed.
554 2000-06-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
556 * async.c (scm_init_async): Switch to standard way of smob
559 2000-06-21 Michael Livshin <mlivshin@bigfoot.com>
561 * guile-doc-snarf.in: use cut instead of sed, that's much much
562 faster. also, don't call basename more than needed. and, to gain
563 a couple of microseconds more, don't call cat needlessly. (thanks
566 2000-06-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
568 * guile-snarf.awk.in, guile-snarf.in, snarf.h: Rename SCM__I to
569 SCM_SNARF_INIT_START, SCM__D to SCM_SNARF_DOC_START, SCM__S to
570 SCM_SNARF_DOCSTRING_START and SCM__E to SCM_SNARF_DOCSTRING_END.
572 2000-06-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
574 * eval.c, eval.h (scm_top_level_lookup_closure_var): Added.
575 #include "libguile/fluids.h".
577 * eval.h (SCM_TOP_LEVEL_LOOKUP_CLOSURE): New macro which replaces
578 SCM_CDR (scm_top_level_lookup_closure_var) everywhere.
580 * root.h (scm_top_level_lookup_closure_var,
581 scm_system_transformer): Removed. (It's no sense in having the
582 *variable* be a "fluid".)
584 * root.c (mark_root): Removed marking of
585 s->top_level_lookup_closure_var and s->system_transformer.
587 * modules.c (scm_selected_module): the_module is now a fluid.
589 2000-06-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
591 * gc.h, tags.h: Be kind to compilers which must see hash signs in
592 column 0. (Thanks to Ian Grant.)
594 * numbers.h: Put #ifdef HAVE_LONG_LONGS around declarations using
595 the long_long type. (Thanks to Bernard Urban.)
597 2000-06-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
599 * gc.c, gc.h (scm_default_init_heap_size_1,
600 scm_default_min_yield_1, scm_default_init_heap_size_2,
601 scm_default_min_yield_2, scm_default_max_segment_size): New global
602 variables. Can be customized by the application before booting
603 Guile. (We might want to be able to control these parameters
604 dynamically through the "options interface" in the future, but
605 note that that is additional functionality. Here we're giving
606 default values which the environment variables can override.)
608 * list.c (scm_cons_star): Updated comment.
610 * smob.h: Changed comments for scm_make_smob_type and
611 scm_make_smob_type_mfpe, warning that the latter might be
612 deprecated in a future release.
614 2000-06-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
616 * list.[ch] (scm_cons_star/cons*): Renamed from
619 * list.[ch] (scm_list_star/list*): Provided as a deprecated alias
620 for scm_cons_star/cons*.
622 * gc.c (scm_protect_object): Updated comment.
624 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX): Removed.
626 * tags.h (SCM_UNPACK_CAR, SCM_NDOUBLE_CELLP): Removed.
628 2000-06-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
630 * init.c, init.h (scm_initialized_p): Renamed from `initialized'
633 * gdbint.c (gdb_print): Print warning instead of calling scm_write
634 if Guile isn't yet initialized.
636 * print.c (scm_current_pstate, scm_make_print_state): Simplified
637 tests, using the assumption that Guile has been initialized.
639 Sun Jun 18 14:45:21 2000 Greg J. Badros <gjb@cs.washington.edu>
641 * print.c (s_scm_current_pstate): Do not segfault when the
642 print_state_pool is unitialized in `current-pstate', and better
643 verify its state before altering it in scm_make_print_state().
645 2000-06-18 Michael Livshin <mlivshin@bigfoot.com>
647 * scmsigs.c (s_scm_sigaction): guard the SIGIOT case with an
648 #ifdef -- it's missing on at least one platform. (thanks to
651 2000-06-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
653 * list.c (list*): Added documentation from common-list.scm.
655 2000-06-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
657 * gc.c (scm_unprotect_object): The reference count is guaranteed
658 to be a positive number.
660 2000-06-15 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
662 * eval.c: Updated comment above scm_map.
664 2000-06-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
666 * gc.c (scm_protect_object): Avoid looking up the object handle
668 (scm_unprotect_object): Abort if scm_unprotect_object is called on
669 an unprotected object.
671 2000-06-14 Michael Livshin <mlivshin@bigfoot.com>
673 * gc.c (scm_unprotect_object): fix a nasty typo bug (thanks to
676 2000-06-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
678 * socket.c (scm_getsockopt): Changed type for `optlen' from int to
680 (scm_accept, scm_getsockname, scm_getpeername, scm_recvfrom):
681 Ditto for `tmp_size'.
682 (scm_addr_buffer_size): Changed type from int to size_t.
684 * random.c: #include <string.h>. (Needed by memcpy.)
686 * guile-snarf.awk.in: Replace the dot_doc_file arg with "-",
687 indicating stdin, instead of "" and don't reset ARGC. This is a
688 workaround for `nawk' in AIX 4.3 on RS6000 but, as far as I know,
689 it is correct, and perhaps even better.
691 2000-06-14 Gary Houston <ghouston@arglist.com>
693 * scmsigs.c (scm_init_scmsigs): if HAVE_SIGINTERRUPT is not
694 defined, add SA_RESTART to the sigaction flags correctly
695 (thanks to Dale P. Smith).
697 2000-06-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
699 * strings.c: #include <string.h>. (Thanks to Bill Schottstaedt.)
701 * net_db.c (scm_resolv_error): Only use macro NETDB_INTERNAL if
702 defined. It isn't on sgi irix 5.3. (Thanks to Bill Schottstaedt.)
704 * Makefile.am (.c.doc): Pipe output (the .x contents) to /dev/null.
706 2000-06-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
708 * fports.c (scm_setvbuf): Use `free' instead of `scm_must_free'
709 since read and write buffers are allocated by `malloc'.
711 * Makefile.am: Removed old test code.
713 * gh_test_c.c, gh_test_repl.c: Removed.
715 2000-06-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
717 * iselect.c (SCM_NLONGBITS): Add workaround for the Sun 4.2
720 * inet_aton.c (inet_aton): Cast init value for `cp'.
722 * ramap.c (s_scm_array_fill_x): Cast `ve' properly in case
725 * symbols.c (scm_intern_obarray_soft,
726 scm_sysintern0_no_module_lookup): Cast `name' to unsigned char ptr
727 in calls to scm_strhash.
729 * strports.c (st_resize_port): Substituted SCM_UCHARS for
731 (st_write): Cast argument to strncpy to char ptr.
732 (scm_mkstrport): Substituted SCM_ROUCHARS for SCM_ROCHARS.
733 (scm_strport_to_string): Cast argument to scm_makfromstr to char
736 * ports.c (scm_ungetc): Cast value to unsigned char ptr before
737 storing in putback_buf.
738 (scm_unread_string): Substituted SCM_ROCHARS for SCM_ROUCHARS.
740 * ioext.c (s_scm_read_line): Cast result of call to
741 scm_do_read_line to unsigned char ptr.
743 * gdbint.c (SEND_STRING): Cast argument to char pointer.
745 * fports.c (fport_flush): Declare `ptr' as unsigned char (was
748 * Makefile.am (DOT_DOC_FILES): List doc-files explicitly. (We
749 shouldn't use Make rules which aren't supported by most Make
751 (OMIT_DEPENDENCIES): Defined to "libguile.h ltdl.h". (We don't
752 want these dependencies recorded, since they would get bogus
753 relative paths; libguile.h is only used in gh.h and guile.c.)
754 (EXTRA_DOT_X_FILES, EXTRA_DOT_DOC_FILES): New variables.
755 (guile-procedures.txt): Depend on EXTRA_DOT_DOC_FILES.
756 (modinclude_HEADERS): Removed kw.h.
758 * guile-snarf.in: Change regexp "^SCM__I" --> "^ *SCM__I".
759 (The preprocessor might insert spaces before the identifier.)
761 * snarf.h (SCM_SNARF_HERE, SCM_SNARF_INIT, SCM_SNARF_DOCS):
762 Renamed from SCM_HERE, SCM_INIT, SCM_DOCS.
764 * smob.h (scm_smobfuns): Removed deprecated type.
766 * smob.c, smob.h (scm_newsmob): Removed deprecated function.
767 (Replaced by `scm_make_smob_type'.)
769 * keywords.c (scm_tc16_kw): Removed deprecated type.
770 (Replaced by scm_tc16_keyword.)
772 * kw.h: Removed deprecated header file.
774 * evalext.c (serial-map): Removed deprected alias for scm_map.
775 (Has been replaced by `map-in-order'.)
777 * ramap.c (serial-array-copy!, serial-array-map!): Removed
778 depracted aliases. (Replaced by `array-copy-in-order!' and
779 `array-map-in-order'.)
781 2000-06-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
783 * gc.h (SCM_VALIDATE_CELL): Rewritten.
784 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
785 SCM_SET_CELL_OBJECT): Use new version of SCM_VALIDATE_CELL.
786 (Thanks to Han-Wen Nienhuys.)
788 2000-06-10 Michael Livshin <mlivshin@bigfoot.com>
790 * guile-doc-snarf.in: don't pipe the CPP output right into sed --
791 write it to the temp file first and check the CPP return code.
792 (I introduced this bug earlier, and this probably caused people
793 with non-GNU C preprocessors to get empty *.x files and not to
794 have the build fail right away...).
796 * scmsigs.c (s_scm_sigaction): guard the SIGSYS case with an ifdef
797 -- at least my libc5-based Linux system doesn't define SIGSYS.
799 2000-06-08 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
801 * snarf.h, guile-snarf.awk.in, guile-snarf.in: Replaced snarf
802 markers with identifiers (SCM__I, SCM__D, SCM__S, SCM__E).
803 (Thanks to Bernard Urban.)
805 2000-06-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
807 * modules.c (scm_system_module_env_p): Fixed detection of system
810 2000-06-06 Marius Vollmer <mvo@zagadka.ping.de>
812 * scmsigs.c (scm_sigaction): Silently ignore setting handlers for
813 `program error signals' because they can't currently be handled by
816 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
818 * procs.h (SCM_SET_SUBRF): Added.
820 * procs.c (scm_make_subr_opt): Don't assign to SCM_SUBRF, use
821 SCM_SET_SUBRF instead. Thanks to Bernard Urban for the bug
824 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
826 * gc.h (SCM_CARLOC, SCM_CDRLOC): Don't take the address of a SCM
829 * sort.c (scm_sorted_p, scm_merge, scm_merge_list_x,
830 scm_merge_list_step): Don't take the address of SCM_CAR. Use
831 SCM_CARLOC instead. Thanks to Bernard Urban for the bug report.
833 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
835 * boolean.h (SCM_TRUE_P): Removed, as people might use it as a
836 replacement for !SCM_FALSEP.
838 * backtrace.c (display_error_body), boolean.h (SCM_BOOLP), gc.c
839 (scm_unhash_name), gh_data.c (gh_module_lookup), load.c
840 (scm_primitive_load), print.c (scm_simple_format), procs.c
841 (scm_procedure_documentation), procs.h (SCM_TOP_LEVEL), ramap.c
842 (scm_array_fill_int), scmsigs.c (scm_sigaction), stacks.c
843 (narrow_stack, scm_make_stack, scm_stack_id), symbols.c
844 (scm_string_to_obarray_symbol), throw.c (scm_catch,
845 scm_lazy_catch, scm_ithrow), unif.c (scm_make_uve, scm_array_p,
846 scm_array_set_x, scm_bit_set_star_x, scm_bit_count_star),
847 validate.h (SCM_VALIDATE_BOOL_COPY, SCM_VALIDATE_PROC): Replace
848 uses of SCM_TRUE_P (x) with SCM_EQ_P (x, SCM_BOOL_T).
850 2000-06-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
852 * eval.c (scm_badformalsp): New static function.
853 (SCM_CEVAL): Check arguments for procedure-with-setter closures.
854 (Thanks to Keisuke Nishida.)
856 The major reason for Guile's slow loading speed has been the fact
857 that a chain of Scheme level procedures has been evaluated for
858 every top-level symbol lookup during the first pass through the
861 The following is a kludge which I suggested four years ago, and
862 which I've repeatedly suggested since. Personally, I've never
863 been bothered by Guile's slow loading speed, so I thought I would
864 let someone else do it...
866 But since the new environments will be included first in
867 Guile-1.5, I thought it would make people happy to get the kludge
870 * modules.c: Added #include "libguile/vectors.h";
871 Added #include "libguile/hashtab.h";
872 Added #include "libguile/struct.h";
873 Added #include "libguile/variable.h";
874 Capture Scheme level `module-make-local-var!' to be used in the
875 standard eval closure.
876 (scm_standard_eval_closure): New primitive.
878 * modules.h (scm_standard_eval_closure): Declare.
880 * eval.c (scm_lookupcar): Test for !SCM_CONSP (SCM_CAR (env))
881 instead of SCM_TRUE (scm_procedurep (SCM_CAR (env))).
883 * symbols.c (scm_sym2vcell): Bypass dispatch in the evaluator for
884 standard eval closures.
886 * variable.c: Code layout fixes.
888 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
890 * Makefile.am: Added LIBS line to libpath which accidentally
891 disappeared in the change of 2000-06-01.
892 (Thanks to Dale P. Smith.)
894 2000-06-03 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
896 * scmsigs.c (scm_segfault): Removed. (Was probably added by
897 mistake since it is not mentioned in ChangeLog.)
899 * gc.h (SCM_VALIDATE_CELL): Cast result to (void) in order to
900 avoid compiler warnings in gcc. (Does this work for other
903 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
905 * gc.h (SCM_VALIDATE_CELL): Don't "use" the value returned by
907 (SCM_CARLOC, SCM_CDRLOC): Define directly instead of using
908 SCM_CELL_OBJECT_0 and SCM_CELL_OBJECT_1. It's not correct to take
909 the address of these expressions since they use SCM_VALIDATE_CELL.
910 (Thanks to Bernard Urban.)
912 * dynl.c: Changed #include <ltdl.h> --> #include
913 "libltdl/ltdl.h". (Thanks to Bill Schottstaedt.)
915 2000-06-01 Craig Brozefsky <craig@red-bean.com>
917 * Makefile.am: libguile_la_LDFLAGS gets -version-info args
918 from GUILE-VERSION definition of LIBGUILE version. Added to
919 libpath.h definitions for guileversion and libguileversion which
920 both get their values from GUILE-VERSION definition.
922 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
924 * numbers.h (SCM_BIGP): Don't use SCM_SMOB_PREDICATE in header
925 file: Code using numbers should not be required to include
928 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
930 * coop-threads.c.cygnus, coop-threads.h.cygnus, fsu-pthreads.h,
931 mit-pthreads.c, mit-pthreads.h: Deleted.
933 * Makefile.am (EXTRA_DIST), scmsigs.c, threads.[ch]: Drop
934 references to deleted files and fsu/mit thread support in
937 2000-05-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
939 * hooks.c (symbol_name, scm_create_hook): Restored the original
940 behaviour of scm_create_hook. Changing it was bad as Carl
941 R. Witty has pointed out.
943 * gc.c (scm_init_gc): We can still rely on scm_create_hook to
946 2000-05-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
948 * gc.c (scm_init_gc): Protect scm_after_gc_hook, since this will
949 soon not be done by scm_create_hook any longer.
951 * hooks.c (make_hook, print_hook, scm_create_hook,
952 scm_make_hook_with_name, scm_make_hook), hooks.h (SCM_HOOK_NAME,
953 SCM_HOOK_PROCEDURES, SCM_SET_HOOK_PROCEDURES,
954 scm_make_hook_with_name), init.c (scm_boot_guile_1): Hooks no
955 longer have names. As an intermediate solution, the name
956 predicate is emulated via object properties, but use of this
957 feature is deprecated.
959 * hooks.h (scm_free_hook): Removed, as it is never defined.
961 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
963 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_FIXABLE):
964 Un-deprecated since otherwise user code can't determine whether a
965 number fits into an inum any longer. The names should be changed
968 * numbers.c (scm_big2inum): Eliminated use of SCM_UNEGFIXABLE.
970 * tags.h (SCM_UNPACK_CAR): Deprecated.
972 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
974 * filesys.h (SCM_OPDIRP), fluids.h (SCM_FLUIDP, SCM_FLUID_NUM),
975 fports.h (SCM_OPFPORTP, SCM_OPINFPORTP, SCM_OPOUTFPORTP), hooks.h
976 (SCM_HOOK_ARITY), keywords.h (SCM_KEYWORDP, SCM_KEYWORDSYM),
977 numbers.h (SCM_NUMP, SCM_BIGSIGN, SCM_BDIGITS, SCM_NUMDIGS):
978 Replace SCM_UNPACK_CAR appropriately. Don't access cells via
979 SCM_{SET}?C[AD]R unless they are known to be cons cells.
981 * gc.c (scm_heap_seg_data_t, scm_mark_locations, scm_cellp,
982 init_heap_seg): Remove unused struct member variable 'valid'.
984 2000-05-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
986 * fports.c (fport_write), ports.c (scm_markstream, scm_port_mode,
987 scm_print_port_mode), ports.h (SCM_OPPORTP, SCM_OPINPORTP,
988 SCM_OPOUTPORTP, SCM_INPUT_PORT_P, SCM_OUTPUT_PORT_P, SCM_OPENP),
989 procs.h (SCM_CLOSCAR), unif.h (SCM_ARRAY_NDIM, SCM_ARRAY_CONTP),
990 variable.h (SCM_VARIABLEP): Replace SCM_UNPACK_CAR
993 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
995 * gc.c (free_list_length), hash.c (scm_hasher), macros.c
996 (scm_macro_type), objects.c (scm_class_of), options.c
997 (scm_options), print.c (scm_iprin1), strports.c (st_seek), throw.c
998 (SCM_LAZY_CATCH_P): Replace SCM_UNPACK_CAR appropriately.
1000 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
1002 * eval.c (scm_macroexp, SCM_CEVAL, scm_force), tags.h: Replace
1003 SCM_UNPACK_CAR with SCM_CELL_TYPE or SCM_CELL_WORD_0.
1005 * eval.c (scm_force): Add documentation.
1007 * eval.c (scm_force, scm_cons_source): Don't access cells via
1008 SCM_{SET}?C[AD]R unless they are known to be cons cells.
1010 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
1012 * strings.h (SCM_NSTRINGP, SCM_NRWSTRINGP), tags.h
1013 (SCM_NDOUBLE_CELLP), vectors.h (SCM_NVECTORP): Deprecated.
1015 * gc.c (scm_igc), gc.h (SCM_PTR_MASK, SCM_PTR_LT): Removed #ifdef
1016 nosve #endif conditionally compiled code.
1018 2000-05-23 Michael Livshin <mlivshin@bigfoot.com>
1020 * gc.c (scm_heap_seg_data_t): fixed comment for the `span' member.
1022 2000-05-22 Michael Livshin <mlivshin@bigfoot.com>
1024 * guile-doc-snarf.in: put the preprocessed file through sed to
1025 trim all lines to 1024 chars. I hope it doesn't break anybody's
1026 sed. we'll see. (note: this is lossy trimming, i.e. the spill
1027 isn't wrapped around but actually chopped off. this seemed to me
1028 safe because the current snarfer doesn't understand multi-line
1029 cookies anyway. in the long term, it would be nice not to depend
1030 on AWK for anything.)
1032 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): reverted
1033 the previous change to this macros, after deciding to torture the
1036 2000-05-21 Michael Livshin <mlivshin@bigfoot.com>
1038 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): brought
1039 the yucky, ugly and nasty conditional compilation back. sorry,
1040 but it was either that or requiring GAWK to build Guile.
1041 (lots of places): removed the code that implemented the old GC
1044 * init.c (scm_boot_guile_1): removed the code conditioned on
1045 !GUILE_NEW_GC_SCHEME.
1047 * __scm.h: (GUILE_NEW_GC_SCHEME): removed.
1049 * gc.c (scm_protect_object, scm_unprotect_object): change the
1050 implementation to more efficient (at least in the time complexity
1051 sense). the calls should now also be thread-safe -- I suspect
1052 that people expect them to be. (thanks to Han-Wen Nienhuys)
1053 (lots of places): removed the code that implemented the old GC
1056 * hashtab.c (scm_hash_fn_create_handle_x): add missing
1057 SCM_REALLOW_INTS before return. I really wonder about the
1058 possible interactions between hashtables, threads & GC. it
1059 doesn't look healthy at all.
1061 2000-05-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
1063 * unif.c (scm_bit_count): Fixed the parameter checks. Thanks to
1066 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
1068 * __scm.h (SCM_DEBUG_CELL_ACCESSES), gc.h (SCM_): Added as a new
1069 debug option to verify all accesses to cells actually access
1070 objects on the heap.
1072 * gc.h (SCM_VALIDATE_CELL): Added. Only performs validation if
1073 SCM_DEBUG_CELL_ACCESSES is set to 1.
1075 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
1076 SCM_SET_CELL_OBJECT): Use SCM_VALIDATE_CELL to check every cell
1079 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
1081 * gh_data.c (gh_scm2chars, gh_scm2shorts, gh_scm2longs,
1082 gh_scm2floats, gh_scm2doubles): Change !SCM_NIMP to SCM_IMP.
1084 * gc.c (scm_cellp): Fixed and simplified.
1086 * throw.c (JBJMPBUF, SETJBJMPBUF, SCM_JBDFRAME, SCM_SETJBDFRAME,
1087 make_jmpbuf, scm_init_throw): Now using double cells to represent
1088 jump buffers when using debug extensions.

1099 * gh.h gh_data.c (gh_int2scmb): Deprecated.
1101 2000-05-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
1103 * __scm.h (SCM_DEBUG_REST_ARGUMENT): Renamed from
1104 SCM_DEBUG_REST_ARGUMENTS in order to clarify that we don't test
1105 the actual arguments in the list, but rather the rest argument as
1106 a list of arguments.
1108 * validate.h (SCM_VALIDATE_REST_ARGUMENT): Added.
1110 * async.c (scm_noop), eval.c (scm_map, scm_for_each), list.c

1118 scm_dynamic_link, scm_init_dynamic_linking), dynl.h
1119 (scm_dynamic_link): Removed possibility to pass flags to
1120 scm_dynamic_link, as it had no effect anyway.
1122 * filesys.c (scm_fcntl): Made single optional rest argument into
1123 a standard optional argument.
1125 * hooks.c (scm_run_hook): A list of rest arguments is never
1128 * list.c (scm_append, scm_append_x), stacks.c (scm_make_stack),
1129 strings.c (scm_string_append): Don't perform half-hearted checks
1130 to see whether the rest argument forms a proper list any more, use
1131 SCM_VALIDATE_REST_ARGUMENTS instead.
1133 * ports.c (scm_close_all_ports_except): Accept empty list of rest
1136 * posix.c (scm_convert_exec_args), print.c (scm_simple_format):
1137 Simplify verification of rest argument.
1139 * stacks.c (scm_make_stack), stacks.h (scm_make_stack), throw.c

1145 scm_enclose_array, scm_array_in_bounds_p): Make first mandatory
1146 rest argument into a standard mandatory argument.
1148 2000-05-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
1150 * __scm.h: Added SCM_DEBUG as default debug option. (Thanks to
1151 Keisuke Nishida for the suggestion.) Added debug option
1152 SCM_DEBUG_REST_ARGUMENTS.
1154 * eval.c (scm_map, scm_for_each): Make sure all lists have the
1155 same length. Also, removed redundant parameter checks.

1159 * Makefile.am: Let 'make clean' remove *.x and *.doc files.
1161 * __scm.h: Improved explanation of giving options to make.
1163 * __scm.h (SCM_DEBUG_TYPING_STRICTNESS), tags.h
1164 (SCM_STRICT_TYPING, SCM_DEBUG_TYPING_STRICTNESS): Renamed
1165 SCM_STRICT_TYPING to SCM_DEBUG_TYPING_STRICTNESS and moved the
1166 corresponding declaration and comment to __scm.h.
1168 * _scm.h (errno), gc.h (SCM_CELLPTR, SCM_PTR_LT), numbers.c
1169 (scm_remainder, scm_modulo), numbers.h (SCM_SRS, SCM_MAKINUM,
1170 SCM_INUM): Removed conditionally compiled code for Turbo C.
1172 * gdbint.c (gdb_maybe_valid_type_p): Eliminated call to scm_tag.
1173 That check can be assumed to be redundant except for very rare
1174 conditions that actually indicate broken heap data.
1176 2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
1178 * numbers.c (scm_logcount, scm_integer_length): Reordered
1181 2000-05-15 Gary Houston <ghouston@arglist.com>
1183 * stime.c (scm_strftime): don't reset TZ if zone is an empty
1184 string. append a "0" to the zone for TZ.
1186 2000-05-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
1188 * numbers.c (scm_logbit_p, scm_bit_extract): Reordered dispatch
1191 (scm_bit_extract): Fixed handling of bignums.
1193 2000-05-15 Dirk Herrmann <D.Herrmann@tu-bs.de>

1206 * fports.c (scm_fport_buffer_add), ports.c (scm_input_port_p,
1207 scm_output_port_p), print.c (scm_get_print_state), validate.h
1208 (SCM_VALIDATE_CHAR): Replace use of deprecated macros
1209 SCM_INPORTP, SCM_OUTPORTP, SCM_ICHRP by SCM_INPUT_PORT_P,
1210 SCM_OUTPUT_PORT_P, SCM_CHARP, respectively.
1212 2000-05-14 Gary Houston <ghouston@arglist.com>
1214 * stime.c (scm_strftime): if HAVE_TM_ZONE is not defined, hack the
1215 TZ environment variable so that the %Z format returns the zone
1216 from the input vector instead of the system default.
1218 from Keisuke Nishida:
1219 * fports.c (scm_setvbuf): minor docstring fix.
1220 * ports.h (scm_generic_fgets): obsolete prototype deleted.
1222 2000-05-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
1224 * __scm.h: Added new section for debugging options.
1226 (SCM_DEBUG_DEPRECATED): If 1, no deprecated code is included to
1227 help developers to get rid of references to deprecated code.
1229 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_UNEGFIXABLE,
1230 SCM_FIXABLE, SCM_FLOBUFLEN): These macros are no longer provided
1231 as part of the interface and are marked as deprecated in the
1234 * numbers.c (scm_make_real, scm_make_complex): Inlined the
1235 corresponding macros SCM_NEWREAL and SCM_NEWCOMPLEX,
1238 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX, SCM_INEXP, SCM_CPLXP,
1239 SCM_REAL, SCM_IMAG, SCM_REALPART, scm_makdbl, SCM_SINGP,
1240 SCM_NO_BIGDIG, SCM_NUM2DBL, scm_dblproc): Deprecated.
1242 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1244 * gc.h (scm_cell, SCM_CELL_WORD, SCM_CELL_OBJECT,
1245 SCM_SET_CELL_WORD, SCM_SET_CELL_OBJECT): Scheme cells now consist
1246 of two scm_bits_t values instead of two SCM values, because it is
1247 legal for cell entries to hold values that are not scheme objects.
1249 (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR):
1250 Use SCM_SETC[AD]R to modify contents of pairs.

1254 * numbers.c (IS_INF, isfinite): Added FIXME comment.
1256 (scm_abs, scm_magnitude): Make these two independent of each
1257 other. scm_abs now reports an error if given a complex argument.
1259 (scm_istr2flo, scm_integer_p). Use SCM_REAL_VALUE instead of
1260 SCM_REALPART if the object is known to be real.
1262 (scm_init_numbers): No need to use SCM_NEWREAL macro for speed
1265 * numbers.h (SCM_SINGP): Set to 0 instead of SCM_BOOL_F.
1267 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>

1273 gh_scm2doubles), hash.c (scm_hasher), ramap.c (scm_array_fill_int,
1274 ramap_rp, scm_array_map_x), random.c (vector_scale,
1275 vector_sum_squares), unif.c (scm_make_uve, scm_array_p,
1276 scm_array_set_x): Use SCM_REAL_VALUE instead of SCM_REALPART if
1277 the object is known to be real. Use SCM_COMPLEXP instead of
1278 deprecated SCM_CPLXP. Use SCM_INEXACTP instead of deprecated
1281 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1283 * numbers.c: No need to include unif.h.
1285 (IS_INF): Returned to old test for now: x == x + 1 will not work
1286 for large numbers due to rounding errors.
1287 Thanks to Kalle Olavi Niemitalo.
1289 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
1291 * numbers.c (scm_divbigdig): Removed outdated comment.
1293 (scm_number_to_string, scm_string_to_number, scm_number_p,
1294 scm_real_p, scm_integer_p, scm_inexact_p, scm_gr_p, scm_leq_p,
1295 scm_geq_p, scm_make_rectangular, scm_make_polar,
1296 scm_inexact_to_exact): Added comments.
1298 (add1, scm_init_numbers): Removed add1.
1300 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
1302 * numbers.c (IS_INF): The new test is x == x + 1. The old test
1303 x == x/2 did not work for zero values. Thanks to Han-Wen Nienhuys
1306 (scm_number_to_string, scm_sum, scm_difference, scm_two_doubles,
1307 scm_num2long, scm_num2long_long, scm_num2ulong): Reordered
1310 2000-05-09 Marius Vollmer <mvo@zagadka.ping.de>
1312 * scmsigs.c (take_signal): Execute SCM_ASYNC_TICK for SIGSEGV,
1313 SIGILL and SIGBUS signals. These signals are not continuable and
1314 must be handled for real right away.
1316 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1318 * numbers.c (scm_zero_p, scm_positive_p, scm_negative_p,
1319 scm_real_part, scm_imag_part, scm_magnitude,
1320 scm_inexact_to_exact): Reordered dispatch sequence.
1322 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1324 * feature.c: No need to include "libguile/smob.h"
1326 (scm_loc_features, features, scm_add_feature, scm_init_feature):
1327 Removed variable 'scm_loc_features' as a pointer to the SCM value
1328 holding the features list. Using variable 'features' instead,
1329 which holds the interned pair. Thus, SCM_SETCDR can be used
1330 instead of pointer trickery.
1332 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1334 * alist.c (scm_acons): Use SCM{_SET}?_CELL_OBJECT as long as a
1335 cell is not known to be a valid pair.
1337 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1339 * eval.c (ASRTSYNTAX, scm_m_body, scm_m_letrec1): Removed
1340 ASRTSYNTAX. Using SCM_ASSYNT instead.
1342 (scm_m_body): Don't create a redundant cons cell.

1346 (bodycheck): Removed.
1348 * stacks.c (stack_depth, read_frame, read_frames): Removed
1349 redundant calculation of size, minimized some variable scopes.
1351 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1353 * pairs.c (scm_cons, scm_cons2): Use SCM{_SET}?_CELL_OBJECT as
1354 long as a cell is not known to be a valid pair.
1356 (scm_pair_p): Eliminated redundant SCM_IMP test.
1358 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1360 * eval.c (scm_m_body, scm_macroexp, unmemocopy, scm_eval_args,
1361 scm_deval_args): Eliminated redundant SCM_IMP tests.
1363 * hashtab.c (scm_ihashx, scm_sloppy_assx, scm_delx_x), weaks.c
1364 (scm_make_weak_key_hash_table, scm_make_weak_value_hash_table,
1365 scm_make_doubly_weak_hash_table): Fixed critical sections.
1366 Thanks to Keisuke Nishida.
1368 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1370 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest):
1371 Fixed some goto-related initialization bugs (introduced by me).
1373 2000-05-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
1375 * numbers.h (SCM_INUM0): Uses SCM_MAKINUM instead of SCM_PACK.
1377 * dynl.c (dynl_obj, DYNL_OBJ, get_dynl_obj): Removed.
1379 (DYNL_FILENAME, DYNL_HANDLE): Use SCM_CELL... macros instead of
1382 (SET_DYNL_HANDLE): Added.
1384 (scm_dynamic_object_p): Simplified.
1386 (scm_dynamic_unlink, scm_dynamic_func): Changed comment. Deliver
1387 better error message when accessing unlinked dynamic objects.
1388 Eliminated call to get_dynl_obj.
1390 2000-05-03 Marius Vollmer <mvo@zagadka.ping.de>
1392 * scmsigs.c (orig_handlers) [!HAVE_SIGACTION]: Fix declaration to
1393 be an array of function pointers instead of being a pointer to an
1394 array returning function. Thanks to Kalle Olavi Niemitalo!
1396 2000-05-03 Dirk Herrmann <D.Herrmann@tu-bs.de>
1398 * numbers.c (scm_divbigbig, scm_divbigint), numbers.h
1399 (scm_divbigbig, scm_divbigint): Don't return zero any more to
1400 indicate that a division has a remainder, return SCM_UNDEFINED
1401 instead. It is improbable that anyone actually used these
1402 functions outside of numbers.c. For this reason and due to the
1403 change in behaviour the functions are static now. Thus, if
1404 surprisingly there are users of these functions they will at least
1407 * numbers.c: Removed #ifdef SCM_BIGDIG #endif in those functions,
1408 that already have a clean dispatch order. Note: SCM_BIGDIG is
1411 * numbers.c (scm_inexact_p): Simplified.
1413 * numbers.c (scm_num_eq_p, scm_less_p, scm_max, scm_min,
1414 scm_product, scm_num2dbl, scm_angle): Reordered dispatch
1415 sequence, thereby fixing some comparisons of SCM values with
1418 * numbers.c (scm_divide): Division by zero of inums leads to an
1419 error now. (Formerly, an infinite number was returned.)
1421 Respect the fact, that scm_divbigbig does now return SCM_UNDEFINED
1422 if a division has a remainder.
1424 2000-05-02 Gary Houston <ghouston@arglist.com>
1426 * Makefile.am (INCLUDES): add ${INCLTDL} (thanks to Tim Mooney).
1428 2000-05-02 Dirk Herrmann <D.Herrmann@tu-bs.de>
1430 * numbers.c (scm_logtest, scm_division): Reordered dispatch
1431 sequence, thereby fixing some comparisons of SCM values with
1434 * numbers.h (scm_makdbl): Mark as deprecated at the point of
1437 * eval.c (SCM_CEVAL, SCM_APPLY), gh_data.c (gh_double2scm,
1438 gh_doubles2scm), numbers.c (scm_istr2flo, scm_max, scm_min,

1445 struct.c (scm_struct_ref), unif.c (scm_array_to_list): Replace
1446 call to scm_makdbl with a call to scm_make_real or
1447 scm_make_complex, depending on whether the imaginary part is known
1450 2000-05-01 Gary Houston <ghouston@arglist.com>
1452 * scmsigs.c: fix the definition of orig_handlers for the case
1453 that HAVE_SIGACTION is not defined (thanks to
1454 Kalle Olavi Niemitalo).
1456 * Makefile.am: remove include_HEADERS (was libguile.h)
1457 libguile.h: moved to top level directory.
1459 2000-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1461 * numbers.c (SCM_SWAP): Moved to the top of the file to allow for
1464 * numbers.c (scm_modulo, scm_gcd, scm_lcm, scm_logand, scm_logior,
1465 scm_logxor): Reordered dispatch sequence, thereby fixing some
1466 comparisons of SCM values with integer constants.
1468 * number.c (scm_logtest): Removed some redundant SCM_{N}?IMP
1471 2000-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1473 * numbers.c (scm_quotient, scm_remainder): Removed code that was
1474 conditionally compiled based on BADIVSGNS. BADIVSGNS does not
1475 occur anywhere else throughout guile.
1477 * numbers.c (scm_quotient): Fixed parameter number in error
1480 * numbers.c (scm_remainder): Reordered dispatch sequence.
1482 2000-04-25 Gary Houston <ghouston@arglist.com>

1490 (suggested by Jost Boekemeier).
1492 2000-04-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
1494 * pairs.c (cxrs, scm_init_pairs): Simplify initialization of
1497 * procs.c (scm_init_iprocs), procs.h (scm_subr, scm_iproc,
1498 scm_dsubr, scm_init_iprocs): Removed.
1500 * procs.h (SCM_SUBRF, SCM_DSUBRF): Access the cell words
1501 directly instead of casting a cell to a C struct.
1503 2000-04-22 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1505 Better modularization of GC extensions through new C level GC
1508 * weaks.c (scm_weaks_prehistory): New function: Add
1509 scm_weak_vector_gc_init to scm_before_mark_c_hook; Add

1511 (scm_scan_weak_vectors): New function; added to
1512 scm_after_sweep_c_hook.
1514 * weaks.h (scm_weak_vectors, scm_weaks_prehistory): Added
1517 * guardians.h (scm_guardian_gc_init, scm_guardian_zombify): Are
1520 * guardians.c (scm_guardian_gc_init): Turned into a hook function
1521 and added to scm_before_mark_c_hook.
1522 (scm_guardian_zombify): Turned into a hook function and added to
1523 scm_before_sweep_c_hook.
1525 * async.c (scm_sys_gc_async_thunk): Run after-gc-hook.
1526 Added #include "libguile/gc.h".
1528 * gc.h: Added #include "libguile/hooks.h".
1530 * gc.c: Removed #include "libguile/guardians.h".
1531 (scm_before_gc_c_hook, scm_before_mark_c_hook,
1532 scm_before_sweep_c_hook, scm_after_sweep_c_hook,
1533 scm_after_gc_c_hook): New C level hooks.
1534 (scm_after_gc_hook): New Scheme level hook.
1535 (scm_gc_sweep): Moved scanning of weak vectors to weaks.c.
1536 (scm_igc): Moved initialization of scm_weak_vectors and the call
1537 to scm_guardian_gc_init to respective module.

1560 (DEFS): Added. automake adds -I options to DEFS, and we don't
1562 Removed all -I options except for the root source directory and
1563 the root build directory.
1565 * numbers.c (scm_odd_p, scm_even_p): Use SCM_WRONG_TYPE_ARG
1566 instead of SCM_ASSERT (0, ...). (Some compilers will complain
1567 about control reaching end of function otherwise, and, besides,
1568 the new code is not less clear.)
1570 * gc.c (scm_must_malloc, scm_must_realloc, scm_must_free): Added
1571 calls to malloc debugging functions.

1587 scm_quotient): Reordered dispatch sequence to first handle
1588 immediates, second handle bignums and finally handle generic
1589 functions respectively signal wrong type arguments. Hopefully

1879 * async.h: kill the scm_async_t struct. having a heap cell

1951 separate loop after processing all the currently known live
1952 guardians, so as to not introduce order dependencies (thanks to
1953 Gary Houston). note that the order problems are still there if
1954 some guardians are themselves zombies, but that's a sick case that
1955 I'm not going to worry about.
1956 also, make another outer loop to process zombified
1957 guardians (which are uncovered while marking zombies).

2076 2000-03-31 Dirk Herrmann <D.Herrmann@tu-bs.de>
2078 * gdbint.c (gdb_maybe_valid_type_p), guardians.c (TCONC_EMPTYP,
2079 scm_guardian_zombify): Use SCM_EQ_P to compare SCM values.
2081 * guardians.c (GUARDIAN): Use SCM_CELL_WORD_1 for raw data.
2083 2000-03-31 Dirk Herrmann <D.Herrmann@tu-bs.de>
2085 * ports.h (scm_port): Change type of stream member to scm_bits_t.
2087 * gdbint.c (unmark_port, remark_port), ports.c (scm_markstream),
2088 strports.c (st_resize_port, scm_mkstrport), vports (sf_flush,
2089 sf_write, sf_fill_input, sf_close, scm_make_soft_port): Since
2090 streams are now of type scm_bits_t, SCM streams have to be
2093 * ports.h (SCM_SETPTAB_ENTRY, SCM_SETSTREAM): Cast input to
2096 2000-03-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2098 * coop-defs.h (struct coop_t): Added `sto'-field again because of
2099 binary compatibility---let's remove it next time we alter some
2102 * coop.c (coop_quitting_p, coop_cond_create, coop_mutex_create,
2103 coop_mother, coop_child): New variables.
2104 (mother): New function.
2105 (coop_create): New thread spawning mechanism which uses a "mother
2106 thread". The "dummy" pthreads aren't healthy enough to give birth
2107 to new threads since Linux threads thinks they are asleep.
2109 * coop-defs.h (struct coop_t): Removed dummy_mutex.
2111 * coop-defs.h, coop-threads.c (struct coop_t): Eliminate
2112 `sto'-field when GUILE_PTHREAD_COMPAT is enabled.
2114 2000-03-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
2116 * arbiters.c (scm_make_arbiter), async.c (scm_async), dynwind.c
2117 (scm_internal_dynamic_wind): Smob data is always of type
2120 * arbiters.c (SCM_ARB_LOCKED, SCM_LOCK_ARB, SCM_UNLOCK_ARB):
2121 Access the locking information in cell entry 0 with
2122 SCM_{SET_}?CELL_WORD_0 instead of SCM_*CAR.
2124 * async.c (scm_run_asyncs): Use SCM_NULLP to test for the empty
2127 * dynwind.c (scm_dowinds): Use SCM_EQ_P to compare SCM values.
2129 * ports.h (SCM_PTAB_ENTRY, SCM_SETPTAB_ENTRY): Access the ptab
2130 entry data using SCM_{SET_}?CELL_WORD_1 instead of SCM_{SET}?CDR.
2132 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
2134 * alist.c (scm_sloppy_assq, scm_assq), eq.c (scm_eq_p, scm_eqv_p,
2135 scm_equal_p), list.c (scm_ilength, scm_last_pair, scm_reverse,
2136 scm_sloppy_memq, scm_delq_x, scm_delq1_x), tags.h (SCM_UNBNDP):
2137 Don't use C operators == and != to compare SCM values, use
2140 * boolean.c (scm_boolean_p): Use SCM_BOOLP to determine whether a
2141 SCM value is equal to #t or #f.
2143 * eq.c (scm_eqv_p, scm_equal_p): Don't use SCM_CAR to access the
2144 cell type entry of non immediate objects of unknown type. Use
2145 SCM_CELL_TYPE instead.
2147 * gh_data.c (gh_scm2bool, gh_module_lookup), list.c
2148 (scm_sloppy_memv, scm_sloppy_member, scm_delv_x, scm_delete_x,
2149 scm_delv1_x, scm_delete1_x), scmsigs.c (scm_sigaction): Use
2150 SCM_FALSEP and SCM_TRUE_P to compare SCM values against #f and
2153 * list.c (scm_listify): Use SCM_UNBNDP to test for an unbound
2156 2000-03-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2158 * coop-threads.c (scm_call_with_new_thread, scm_spawn_thread,
2159 scm_make_mutex, scm_make_condition_variable): Cast data to
2160 scm_bits_t in SCM_SET_CELL_WORD and SCM_NEWSMOB macros.
2162 * coop.c (coop_create): Set `specific' field, not `data' to NULL.
2164 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
2166 * smob.h (SCM_NEWSMOB, SCM_NEWSMOB2, SCM_NEWSMOB3, SCM_SMOB_DATA,
2167 SCM_SET_SMOB_DATA, SCM_TC2SMOBNUM, SCM_SMOBNUM): To access smob
2168 data, use SCM_{SET_}?CELL_TYPE or SCM_{SET_}?WORD_[1-3].
2170 Note that this implies that smob data has always to be passed as
2171 values of type scm_bits_t.
2173 2000-03-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2175 * threads.c (scm_init_threads): Pass 0 size to scm_make_smob_type
2176 for scm_tc16_thread. As the current COOP threads are written, GC
2177 is not supposed to manage storage for threads.
2179 * error.c (scm_error): Don't try to throw an error if
2180 scm_gc_heap_lock is true.
2182 * coop.c (coop_finish): New function. Called at exit.
2183 (coop_aborthelp): Free thread structures when threads die.
2184 Finished LinuxThreads compatibility support => COOP threads now
2185 mesh with LinuxThreads.
2187 * coop-threads.c (scm_call_with_new_thread, scm_spawn_thread):
2188 Changed SETCDR --> SET_CELL_WORD_1.
2190 * coop-threads.c (scheme_launch_thread): Set word 1 of handle to 0
2193 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
2195 * boolean.h (SCM_TRUE_P): New macro.
2197 * boolean.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOLP), pairs.h
2198 (SCM_NULLP, SCM_NNULLP): Use SCM_EQ_P to compare SCM values.
2200 2000-03-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
2202 * continuations.h (SCM_CONTREGS, SCM_SET_CONTREGS): New macros to
2203 access continuation data.
2205 (SCM_SETJMPBUF): Deprecated. Use SCM_SET_CONTREGS instead.
2207 (SCM_JMPBUF, SCM_DYNENV, SCM_THROW_VALUE, SCM_BASE, SCM_SEQ,
2208 SCM_DFRAME): Use SCM_CONTREGS instead of SCM_CHARS to access
2211 * continuations.c (scm_make_cont), init.c (start_stack),
2212 root.c (scm_internal_cwdr): Use SCM_SET_CONTREGS instead of
2215 2000-03-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
2217 * symbols.h (SCM_LENGTH, SCM_SETLENGTH): Access the length field
2218 of strings and symbols by using SCM_{SET_}?CELL_WORD_0.
2220 (SCM_CHARS, SCM_UCHARS, SCM_SETCHARS): Use SCM_{SET_}?CELL_WORD_1
2221 to access the char * field of strings and symbols.
2223 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
2225 * gc.h (SCM_NEWCELL, SCM_NEWCELL2): Use SCM_SET_CELL_TYPE to set
2226 the type entry of a new cell. Added a comment about things to
2227 remember when updating the list of free cells.
2229 (SCM_FREEP, SCM_MARKEDP): Use SCM_CELL_TYPE to access the type
2232 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
2234 * pairs.h (SCM_CAR, SCM_CDR, SCM_SETCAR, SCM_SETCDR): Use
2235 SCM_CELL_OBJECT and SCM_SET_CELL_OBJECT. This change implies that
2236 with strict type checking enabled these macros will only work if
2237 given valid SCM parameters.
2239 (SCM_GCCDR): Moved to tags.h.
2241 * tags.h (SCM_GCCDR): Moved here from pairs.h.
2243 2000-03-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
2245 * tags.h (SCM2PTR, PTR2SCM): Moved to gc.h.
2247 * pairs.h (scm_cell, SCM_CELLPTR, SCM_CELL_WORD*, SCM_CELL_OBJECT*,
2248 SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*, SCM_CELL_TYPE,
2249 SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK, SCM_PTR_GT,
2250 SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC, SCM_NEWCELL,
2251 SCM_NEWCELL2): Moved to gc.h.
2253 (SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR, SCM_SETAND_CDR,
2254 SCM_SETOR_CAR, SCM_SETOR_CDR): Moved to gc.h. These names should
2255 be changed, though, since the macros are not only pair related.
2259 * gc.h (SCM2PTR, PTR2SCM, scm_cell, SCM_CELLPTR, SCM_CELL_WORD*,
2260 SCM_CELL_OBJECT*, SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*,
2261 SCM_CELL_TYPE, SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK,
2262 SCM_PTR_GT, SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC,
2263 SCM_NEWCELL, SCM_NEWCELL2, SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR,
2264 SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR): Moved here from
2267 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2269 * tags.h (SCM_STRICT_TYPING): New macro that, if defined,
2270 activates strict compile time type checking for variables of
2272 (SCM, SCM_PACK, SCM_UNPACK): Define according to whether
2273 SCM_STRICT_TYPING or SCM_VOIDP_TEST are defined.
2274 (SCM_EQ_P): Defined as a macro equivalent for eq?.
2276 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2278 * tags.h (SCM_POINTERS_MUNGED): Removed.
2280 * gc.c (scm_gc_sweep, init_heap_seg): Removed use of
2281 SCM_POINTERS_MUNGED, thus fixing some illegal casts to SCM.
2283 2000-03-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
2285 * pairs.h (SCM_CELL_OBJECT, SCM_CELL_OBJECT_[0-3],
2286 SCM_SET_CELL_OBJECT, SCM_SET_CELL_OBJECT_[0-3], SCM_CELL_TYPE,
2287 SCM_SET_CELL_TYPE): Added a set of low level macros for accessing
2289 (SCM_CELL_WORD_[0-3]): Renamed from the SCM_CELL_WORD[0-3].
2291 * procs.h, procs.c: Instead of SCM_{SET_}?CELL_WORD[12], use the
2292 newly introduced SCM_{SET_}?CELL_OBJECT_[12] macros.
2294 2000-03-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2296 * tags.h: Disabled definition of SCM_VOIDP_TEST.
2298 Defining SCM as void * introduces problems which haven't been
2299 handled yet. Developers who work with these issues can enable it
2300 in their working copies.
2302 Disabling this definition exposes a set of newly introduced and
2303 older misuses of types which causes warning messages during
2304 compilation. We'll fix this successively.
2306 * gc.c (scm_mark_locations): Changed * (SCM **) X --> * (SCM *) X
2307 in order to obtain a value of type SCM.
2308 (scm_cellp): Updated with new changes to scm_mark_locations.
2310 * continuations.h (SCM_SETJMPBUF): Cast second arg into SCM.
2312 * continuations.c (scm_make_cont): Removed cast of size_t into
2315 * symbols.h (SCM_SETCHARS): Cast second arg into SCM.
2317 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
2319 * numbers.h (SCM_SETNUMDIGS): Use SCM_BIGSIZEFIELD macro for
2320 shifting, not constant. Thanks to Dale P. Smith.
2322 * numbers.c (scm_sum, scm_difference): Don't test a SCM value
2323 for being less than zero. Decode it to a C value first. Again,
2326 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
2328 * numbers.h, ramap.c, struct.h, vectors.h: Don't use SCM2PTR for
2329 non scheme values. If raw data is stored in SCM variables, it has
2330 to be accessed using SCM_UNPACK until a better solution is found.
2332 2000-03-22 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2334 * tags.h (SCM_ECONSP, SCM_NECONSP): More corrections of
2335 pointer-arithmetic induced by the SCM_PACK/UNPACK change.
2337 * print.c (scm_iprin1): SCM_PACK/UNPACK corrections.
2339 * gc.c (scm_gc_sweep): SCM_PACK/UNPACK corrections.
2341 * eval.c (SCM_CEVAL, scm_unmemocar): SCM_PACK/UNPACK corrections.
2343 * dynwind.c (scm_swap_bindings): SCM_PACK/UNPACK corrections.
2345 * async.c, __scm.h: Removed lots of the old async click logic. It
2346 is possible to reinsert it by defining GUILE_OLD_ASYNC_CLICK in
2347 __scm.h. Let's try this out and dump the old code after the
2348 threads reorganization.
2349 (set-tick-rate, set-switch-rate): Conditionally removed.
2351 2000-03-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2353 * gc.c (scm_gc_mark): Bugfix 1: The recent SCM_PACK/UNPACK change
2354 made SCM values into pointers. This turned an arithmetic
2355 computation of the address of the vcell into a pointer-arithmetic
2356 one, thereby screwing up marking of structs.
2357 Bugfix 2: Removed incompletely introduced loop variable `j' used
2358 when protecting the tail array of a struct.
2360 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2362 * struct.h (SCM_STRUCT_DATA): Don't cast SCM values to pointers.
2364 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2366 * symbols.h, symbols.c (scm_strhash): Declare the string
2367 parameter as constant, since it is not modified.
2369 * symbols.c (scm_intern_obarray_soft,
2370 scm_sysintern0_no_module_lookup): Can now pass constant strings
2371 to scm_strhash without need for casting.
2373 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2375 * vectors.h (SCM_VELTS, SCM_VELTS_AS_STACKITEMS): Don't cast SCM
2376 values to pointers. Use SCM2PTR instead.
2378 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2380 * async.c (scm_set_tick_rate, scm_set_switch_rate): Don't unpack
2381 results of SCM_INUM.
2383 2000-03-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2385 * init.c (scm_boot_guile_1): Renamed GUILE_GC_TRIGGER_1 -->
2386 GUILE_MIN_YIELD_1, GUILE_GC_TRIGGER_2 --> GUILE_MIN_YIELD_2.
2387 GUILE_MIN_YIELD_X now take *positive* fractions of heap size.
2389 * gc.c, gc.h (SCM_MIN_YIELD_1, SCM_MIN_YIELD_2,
2390 min_yield_fraction, min_yield, adjust_min_yield): Renamed from
2391 SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2, gc_trigger_fraction,
2392 gc_trigger, adjust_gc_trigger.
2394 * gc.c (alloc_some_heap): Further improvement of minimal heap size
2396 (SCM_MAX): New macro.
2397 (scm_freelist_t): New field: collected_1. Previous amount of
2399 (gc_sweep_freelist_finish): Trigger based on two last values of
2400 freelist->collected to avoid unnecessary allocation due to
2402 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2):
2403 Adjusted to 45000 cells, 40% and 40%. Gives quick startup
2404 without extra heap allocation.
2406 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2408 * numbers.h (SCM_MAKINUM): The parameter to SCM_MAKINUM should
2409 already be a C value. No need to unpack it.
2411 * numbers.c (scm_long_long2num): Cast the parameter to scm_bits_t
2412 if we know it fits into an inum.
2414 * ramap.c (ramap_rp): An scm_tc7_[ui]vect object does point to a
2415 field of long values. In contrast, SCM_VELTS accesses a field of
2418 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2420 * gc.c (scm_gc_stats): Inserted explanation of local_scm_mtrigger
2422 (scm_gc_yield_1): New variable: Holds previous yield. Used to
2423 make better judgements.
2424 (gc_sweep_freelist_finish): Inserted explanation of use of
2427 * print.h, stacks.h, options.c, options.h: Changed C++
2430 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2432 * tags.h (SCM2PTR, PTR2SCM): Use SCM_PACK / SCM_UNPACK correctly.
2434 * numbers.h (SCM_INUMP, SCM_MAKINUM, SCM_INUM0, SCM_COMPLEX_REAL,
2435 SCM_COMPLEX_IMAG, SCM_NUMP, SCM_BDIGITS): Use SCM_PACK /
2436 SCM_UNPACK / SCM2PTR correctly.
2438 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2440 * gc.c (adjust_gc_trigger): Improved documentation.
2441 (alloc_some_heap): Since gc_trigger is used against
2442 freelist->collected, this is the value which should be used to
2443 predict minimum growth.
2445 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2447 * eval.h: Fix mixup of packed/unpacked SCM values. (Thanks
2448 Thien-Thi Nguyen for the patch.)
2450 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2452 * numbers.c (scm_ash): Fixed typing problems with the second
2453 parameter and added some documentation. (Thanks Thien-Thi Nguyen
2454 for indicating the problem.)
2456 2000-03-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2458 * gc.c, gc.h (scm_gc_yield): New variable.
2459 (adjust_gc_trigger): Use scm_gc_yield.
2460 (alloc_some_heap): Use scm_gc_yield instead of
2461 scm_gc_cells_collected.
2463 * coop-threads.c: Addd #include "root.h", #include "strings.h".
2465 * debug.c: Added #include "root.h". (Thanks to Thien-Thi Nguyen.)
2467 * gc.c (scm_gc_for_newcell, adjust_gc_trigger): Improved GC
2468 trigger adjustmeant: Take yield (freed cells) for all freelists
2470 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Tuned
2471 to 50000 cell heap with 45% trigger.
2472 (scm_gc_cells_collected): Reintroduced.
2473 (SCM_HEAP_SIZE): New macro.
2474 (scm_gc_sweep): Reintroduced correct computation of
2475 scm_cells_allocated.
2476 (scm_freelist_t): Corrected commentary for field `cluster_size':
2477 Clustersize counts objects, not cells; New member
2478 `clusters_allocated'.
2480 2000-03-19 Michael Livshin <mlivshin@bigfoot.com>
2482 * *.[hc]: add Emacs magic at the end of file, to ensure GNU
2485 2000-03-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2487 * threads.h: Added #include "libguile/throw.h". (Thanks to
2490 2000-03-18 Michael Livshin <mlivshin@bigfoot.com>
2492 * tags.h: (SCM_DOUBLE_CELLP, SCM_NDOUBLE_CELLP): new macros (bad
2493 names, anyone got any better ones?)
2495 * gc.h: (typedef struct scm_freelist_t) remove from here.
2497 * gc.c: (CELL_UP, CELL_DN) made these macros take additional
2498 parameter (the span).
2499 (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK) new macros.
2500 (typedef struct scm_freelist_t) moved here from gc.h, it had no
2501 business being externally visible.
2502 (typedef struct scm_heap_seg_data_t) renamed from
2503 scm_heap_seg_data, to be style-compliant.
2504 (scm_mark_locations) if the possible pointer points to a
2505 double-cell, check that it's properly aligned.
2506 (init_heap_seg) align double-cells properly, work with the
2507 assumption that the segment size divides cleanly by cluster size.
2508 (round_to_cluster_size) new function.
2509 (alloc_some_heap, make_initial_segment) use round_to_cluster_size
2510 to satisfy the new init_heap_seg invariant.

2567 Removed reference to genio.h
2569 2000-03-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2571 * gc.c, gc.h: Cleanup of the change of 2000-03-15.
2572 Cluster sizes are now independent of GC trigger values.
2573 GUILE_GC_TRIGGER_n can now specify a relative trigger value:
2574 A negative integer gives fraction of total heap size in percent.
2575 (SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Default values set to -40.
2577 * init.c (scm_boot_guile_1): Introduced new variable
2578 GUILE_MAX_SEGMENT_SIZE; New environment variable names:
2579 GUILE_INIT_SEGMENT_SIZE_1, GUILE_GC_TRIGGER_1,
2580 GUILE_INIT_SEGMENT_SIZE_2, GUILE_GC_TRIGGER_2
2582 2000-03-16 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2584 * __scm.h (GC_FREE_SEGMENTS): Disable this until we have made
2585 freeing of segment work with the new GC scheme. (Thanks to
2586 Michael Livshin.) Oops, also happened to make GUILE_NEW_GC_SCHEME
2587 the default, but I'll let this change stay in CVS Guile since this
2588 code is not expected to contain serious bugs.
2590 2000-03-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2592 * gc.c, gc.h (scm_map_free_list): Define also if GUILE_DEBUG is
2594 (scm_free_list_length): New procedure (GUILE_DEBUG).
2595 Fixed a small but serious bug introduced by the previous change.
2597 * gc.c (scm_gc_sweep): Moved variable n_objects to inner sweep
2598 loop and declare as register.
2600 * gc.c (scm_gc_sweep): Sigh... forgot to clear private freelists
2603 Wed Mar 15 08:27:04 2000 Greg J. Badros <gjb@cs.washington.edu>
2605 * fluids.c: Docstring patch from Keisuke Nishida. Some
2606 reindentation, too, and a couple formals renamed. Should
2607 fluid-set! return UNSPECIFIED instead of a value?
2609 Wed Mar 15 08:24:58 2000 Greg J. Badros <gjb@cs.washington.edu>
2611 * Makefile.am: Separate out DOT_X_FILES and DOT_DOC_FILES, and
2612 generate the latter from the concrete listing of the former. Then
2613 make guile-procedures.txt depend on DOT_DOC_FILES instead of
2614 *.doc, so that rebuilding it works.
2616 Wed Mar 15 08:12:14 2000 Greg J. Badros <gjb@cs.washington.edu>
2618 * libguile.h: Include libguile/validate.h. Thanks Keisuke Nishida!
2620 * guile-snarf.awk.in: Replace docstring line-ending \n" and \n\n"
2621 with nothing and \n, respectively. Thanks Keisuke Nishida for
2622 noticing this problem.
2624 2000-03-15 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2626 * __scm.h (GUILE_NEW_GC_SCHEME): Define this if you want to test a
2627 new way of allocating heap. It makes Guile fast, but still
2630 * gc.c, gc.h, pairs.h, init.c: Implementation of a new way of
2631 allocating heap. The basic idea is to trigger GC every Nth
2632 allocated cell and grow heap when free list runs out. The scheme
2633 has been extended so that GC isn't triggered until all remaining
2634 cells are used. The implementation is also prepared for
2635 development in the direction of POSIX threads.
2637 * gc.c (SCM_EXPHEAP): In order to grow by a factor of 1.5,
2638 SCM_EXPHEAP should return half of the heap size.
2640 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2642 The following change to init.c is only enabled if Guile was
2643 configured with --enable-guile-debug.
2645 * init.c (scm_i_getenv_int): New function.
2646 (scm_boot_guile_1): Use the environment variables
2647 GUILE_INIT_HEAP_SIZE, GUILE_INIT_HEAP_SIZE2 to select heap size if
2648 they exist. (This may be replaced by a Scheme level mechanism in
2651 * objprop.c (s_scm_set_object_property_x): Use scm_assq instead of
2652 scm_assoc. (Thanks to Keisuke Nishida.)
2654 2000-03-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2656 * eval.c, lang.c, lang.h (scm_lisp_nil, scm_lisp_t): Renamed from
2657 scm_nil, scm_t. (Thanks to Keisuke Nishida.)
2659 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2661 * init.c (scm_boot_guile_1): Use same initial segment size for
2662 1-word and 2-word segments. Having the smaller size causes Guile
2663 to GC too often. Obviously something needs to be done to allow
2664 for a smaller 2-word segment without this to happen. (The amount
2665 of heap for each type should be automatically adapted to the
2666 application somehow.)
2668 [Almost all of these changes should be documented in the NEWS
2671 * gc.h (scm_freelist_t): New type.
2673 * pairs.h (SCM_NEWCELL, SCM_NEWCELL2): Use new style freelists.
2675 * gc.c (SCM_INIT_HEAP_SIZE): Changed from 32768 --> 40000 so that
2676 all of Guile basics fits into one segment and there suitable room
2678 (SCM_EXPHEAP): Now takes an argument. Grow by a factor of 1.5
2680 (scm_freelist, scm_freelist2): Now of type scm_freelist_t.
2681 Freelists now contains information about object span, cells
2682 collected and amount of cells in heap segments belonging to the
2684 (scm_heap_size, scm_gc_cells_collected): Removed.
2686 * init.c (scm_boot_guile_1): Make 2-word segment 8K (512 cells).
2688 * Makefile.am (libguile_la_LDFLAGS): Bumped library version
2691 * __scm.h eq.c, eval.c, gc.c, gc.h, gh_data, hash.c, numbers.c,
2692 numbers.h, objects.c, ramap.c, random.c, unif.c, unif.h: Extensive
2693 rewrite of handling of real and complex numbers.
2694 (SCM_FLOATS, SCM_SINGLES): These #ifdef conditionals have been
2695 removed along with the support for floats. (Float vectors are
2698 * tags.h (scm_tcs_bignums): Removed.
2699 (scm_tc16_bigpos, scm_tc16_bigneg): Replaced by scm_tc16_big.
2700 Use SCM_BIGSIGN(x) to test for sign!
2701 (scm_tc16_big): The new bignum type.
2702 (SCM_REAL_PART, SCM_IMAG_PART): Removed.
2704 * numbers.h (SCM_BIGSIGN): Sign moved to bit 16.
2705 (scm_makdbl): Deprecated.
2706 (SCM_NEWREAL, SCM_NEWCOMPLEX): New macros.
2707 (SCM_SINGP): Deprecated.
2709 (SCM_INEXP, SCM_CPLXP): Deprecated.
2710 (SCM_INEXACTP, SCM_COMPLEXP): New macros.
2711 (SCM_COMPLEX_REAL, SCM_COMPLEX_IMAG): Renamed from
2712 SCM_REAL, SCM_IMAG (and now only valid for complex numbers).
2713 (SCM_REAL, SCM_IMAG): New, *deprecated*, selectors which work both
2714 for doubles and complex numbers.
2715 (SCM_REAL_VALUE): New selector for doubles.
2716 (scm_double_t, scm_complex_t): New types.
2719 * numbers.c (scm_floprint, scm_floequal): Removed.
2720 (scm_print_real, scm_print_complex, scm_real_equalp,
2721 scm_complex_equalp): New functions.
2723 * unif.c (scm_makflo): Removed.
2725 * smob.h (SCM_SMOB_PREDICATE): New macro.
2726 (SCM_NEWSMOB2, SCM_RETURN_NEWSMOB2, SCM_NEWSMOB3,
2727 SCM_RETURN_NEWSMOB3): New macros.
2729 1999-11-21 Michael Livshin <mlivshin@bigfoot.com>
2731 The following changes implement primitive support for double cells
2732 (i.e. four-word cells) and change the representation of some
2733 things to multi-cells instead of cons+malloc. (Applied and
2736 * pairs.h (SCM_NEWCELL2): double-cell variants of SCM_NEWCELL.
2737 (SCM_CELL_WORD, SCM_CELL_WORDLOC, SCM_SET_CELL_WORD): primitive
2738 multi-cell access macros (used by the ones below).
2739 (SCM_CELL_WORD[0-3], SCM_SET_CELL_WORD[0-3]): multi-cell access
2742 * gc.c (scm_freelist2): multi-cell freelists.
2743 (inner_map_free_list): map_free_list, parameterized on ncells.
2744 "nn cells in segment mm" was misleading for ncells > 1; changed to
2745 "objects". still print cells too, though.
2746 (scm_map_free_list): rewritten using inner_map_free_list.
2747 (scm_check_freelist): get freelist as parameter, since now we have
2749 (scm_debug_newcell2): multi-cell variants of
2751 (scm_gc_for_newcell): take ncells and freelist pointer as
2753 (scm_gc_mark): add case for tc7_pws (procedures with setters are
2755 (scm_gc_sweep): don't free the float data, since it's not malloced
2757 (init_heap_seg): didn't understand what n_new_objects stood for,
2758 so changed to n_new_cells.
2759 (make_initial_segment): new function, makes an initial segment
2760 according to given ncells.
2761 (scm_init_storage): call make_initial_segment, for ncells={1,2,3}.
2763 * numbers.c (scm_makdbl): no malloc'ing needed, so the
2764 {DEFER,ALLOW}_INTS thing removed.
2766 * numbers.h (struct scm_dbl): changed to represent a double cell,
2767 with the number in the second half.
2769 * dynwind.c: changed the wind-guards representation to double
2772 * procs.c, procs.h: changed the procedure-with-setter representation
2775 * async.c, async.h: made async representation a double cell.
2777 * dynl.c: made dynamic_obj representation a double cell.
2779 2000-03-13 Gary Houston <ghouston@arglist.com>
2781 * ports.c (flush_void_port): renamed to flush_port_default.
2782 (end_input_void_port): renamed to end_input_default.
2784 * init.c (scm_standard_stream_to_port): create a void port instead
2785 of opening /dev/null if the standard file descriptors are bad.
2786 advantages: no portability problems, doesn't waste a file descriptor,
2787 simplifies the code (thanks to Marius for the idea).
2789 * vports.c (s_scm_make_soft_port): call scm_port_non_buffer.
2791 * void ports: make reading from a void port give EOF instead of
2793 * ports.c (s_scm_sys_make_void_port): modified docstring.
2794 (fill_input_void_port): new proc.
2795 (scm_init_ports): set up fill_input_void_port.
2796 * ports.c (scm_port_non_buffer): new proc.
2797 (scm_void_port): call scm_port_non_buffer.
2799 * fports.c (scm_setvbuf): docstring: remove the fcntl documentation
2800 which was incorrectly appended.
2802 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2804 * guile-doc-snarf.in: Don't use absolute path for `sed'. (Note
2805 that we can't use autoconf for this. Autoconf itself relies on
2806 the existence of `sed' somewhere on your path.) (Thanks to Dirk
2809 2000-03-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2811 * Makefile.am (libguile_la_SOURCES): Moved iselect.c here from
2812 EXTRA_libguile_la_SOURCES.
2814 * iselect.h: Always declare scm_internal_select.
2816 * iselect.c (scm_internal_select): Added SCM_ASYNC_TICK at the
2817 end. Also let scm_internal_select be a real function also when
2820 * __scm.h (SCM_TICK): Oops! Forgot to put SCM_ASYNC_TICK here...
2822 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2824 * __scm.h (SCM_ALLOW_INTS, SCM_REALLOW_INTS): Removed call to
2825 SCM_ASYNC_TICK. (This is a preparation for POSIX threads support,
2826 and kind of an experiment: Will this cause problems?)
2828 Sun Mar 12 13:26:30 2000 Greg J. Badros <gjb@cs.washington.edu>
2830 * Makefile.am: Added *.doc to DISTCLEANFILES.
2832 2000-03-12 Gary Houston <ghouston@arglist.com>
2834 * fports.c (scm_fdes_to_port): call fcntl F_GETFL to test that
2835 the fdes is valid before doing anything else. check that
2836 the file descriptor supports the modes required.
2837 (scm_fport_buffer_add): don't throw an error if fstat doesn't
2838 work: just use the default buffer size.
2840 * throw.c: change an outdated comment about scm_internal_catch
2841 BODY: it doesn't take a jumpbuf arg.
2843 * init.c (scm_standard_stream_to_port): install a handler in case
2844 scm_fdes_to_port throws an error. don't check here whether the
2845 file descriptor is valid, since scm_fdes_to_port will do that.
2846 set the revealed count depending on whether the port got the
2847 standard file descriptor.
2848 (stream_body_data): new type.
2849 (stream_body, stream_handler): new procs.
2851 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2853 * stacks.c, stacks.h, struct.c, tags.h, unif.c (scm_bits_t):
2854 Renamed from SCMWORD.
2856 * tags.h (SCM_NCELLP): Removed (SCMWORD).
2858 * arbiters.c (SCM_ARB_LOCKED): Use SCM_UNPACK_CAR.
2860 * async.c, boolean.h, debug.c, dynl.c, dynwind.c, eval.c, eval.h,
2861 feature.h, filesys.h, fluids.h, fports.c, fports.h, gc.c, gc.h,
2862 hash.c, keywords.h, macros.c, numbers.c, numbers.h, objects.c,
2863 objects.h, options.c, pairs.h, ports.c, ports.h, print.c,
2864 procs.h, ramap.c, read.c, smob.c, smob.h, srcprop.h, stacks.c,
2865 stacks.h, strports.c, struct.c, struct.h, tag.c, tags.h,
2866 throw.c, unif.c, unif.h, variable.h, vectors.h, weaks.c,
2867 weaks.h (SCM_PACK, SCM_UNPACK, SCM_UNPACK_CAR): Renamed from
2868 SCM_ASSCM, SCM_ASWORD, SCM_CARW).
2870 * numbers.h (SCM_SRS, SCM_INUM): Corrected SCM_ASSCM/ASWORD fixes.
2872 * alist.c, eval.c, net_db.c, posix.c, print.c, snarf.h, struct.c,
2873 tags.h: Fixed copyright notices.
2875 * struct.c, coop-threads.c: SCM_ASSCM/ASWORD fixes.
2877 2000-03-12 Marius Vollmer <mvo@zagadka.ping.de>
2879 * init.c (scm_standard_stream_to_port): Check whether the file
2880 descriptor is valid and substitute "/dev/null" when not.
2882 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2884 * coop-defs.h (struct timespec): Conditionally defined.
2886 * coop.c (coop_condition_variable_timed_wait_mutex): Use ETIMEDOUT
2889 * readline.c (match_paren): Bugfix: First arg to select is not
2890 number of descriptors but the number of the highest descriptor +
2893 This is a preliminary attempt at a cleanup of the threads support
2894 code. It moves things to better places, makes arguments more
2895 consistent with the POSIX API (which is used in GNOME's glib), and
2896 adds new functionality.
2898 * readline.c (scm_init_readline): Added new arg to scm_init_mutex.
2900 * coop-defs.h (scm_mutex_trylock): New macro: alias for
2902 (scm_cond_init): Changed definition to
2903 coop_new_condition_variable_init.
2905 * coop.c: #include <errno.h>
2906 (coop_timeout_qinsert): Moved here from iselect.c
2907 (coop_new_mutex_init, coop_new_condition_variable_init): New
2908 functions. The strange names are temporary. Use scm_mutex_init
2909 and scm_cond_init instead.
2910 (coop_mutex_trylock): New function. Uses errno.h:EBUSY. errno.h
2911 is ANSI C, but should we check for individual error codes in
2913 (coop_condition_variable_timed_wait_mutex): New function.
2914 (coop_key_create, coop_setspecific, coop_getspecific,
2915 coop_key_delete): New functions.
2917 * iselect.c (coop_timout_qinsert): Moved to coop.c
2919 2000-03-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2921 * pairs.h (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR,
2922 SCM_SETOR_CDR): Corrected SCM_ASSCM/WORD fixes.
2924 * tags.h (SCM_VOIDP_TEST): Renamed from VOIDP_TEST.
2927 * objects.h (SCM_CLASS_FLAGS, SCM_OBJ_CLASS_FLAGS,
2928 SCM_SET_CLASS_INSTANCE_SIZE), struct.h (SCM_STRUCT_VTABLE_DATA),
2929 proc.h (SCM_CLOSCAR): SCM_ASSCM/WORD fixes.
2931 * eval.c (scm_lookupcar1): Inserted SCM_ASWORD in expressions
2934 2000-03-11 Dale P. Smith <dpsm@en.com>, applied by Greg J. Badros, <gjb@cs.washington.edu>
2936 * numbers.c (scm_copy_big_dec, scm_copy_smaller, scm_big_ior,
2937 scm_big_xor, scm_big_and, scm_big_test): Added new lowlevel bignum
2938 logical functions from SCM.
2940 (logand, logior, logxor, logtest, logbit?): Extended scheme
2941 logical functions to use bignums from SCM.
2943 (lognot): Removed call to `SCM_VALIDATE_INUM' that prevented
2944 lognot from using bignums.
2946 Thu Mar 9 11:33:25 2000 Greg J. Badros <gjb@cs.washington.edu>
2948 * vectors.h (SCM_VELTS_AS_STACKITEMS): Added this macro to help in
2949 eliminating some warnings.
2951 * unif.c, strports.c, print.c, options.c: Fix some warnings on
2954 * gc.c, gc.h: Added scm_return_first_int(), and added comment re:
2955 what the scm_return_first* functions do.
2957 2000-03-09 Han-Wen Nienhuys <hanwen@cs.uu.nl>, applied by Greg J. Badros, <gjb@cs.washington.edu>
2959 * libguile/*.[ch]: make a distinction between SCM as a generic
2960 name for a Scheme object (now a void*), and SCM as 32 bit word for
2961 storing tags and immediates (now a long int). Introduced
2962 SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious
2963 code in the process: arbiter.c (use macros), unif.c (scm_array_p),
2965 Wed Mar 8 10:15:59 2000 Greg J. Badros <gjb@cs.washington.edu>
2967 * numbers.c: Use SCM_VALIDATE_LONG_COPY, and longs, not ints, in
2968 various logXXX primitives. Thanks Eric Moore!
2970 Tue Mar 7 08:05:22 2000 Greg J. Badros <gjb@cs.washington.edu>
2972 * run-test, remaining-docs-needed: Added these scripts. The
2973 second one is only temporary until the docstring additions are
2974 complete. run-test may best live on, but is here mostly for
2975 convenience and awareness for now.
2977 * hash.c: Docs, minor cleanup patch from Dirk Herrman.
2979 Thu Mar 2 16:06:58 2000 Greg J. Badros <gjb@cs.washington.edu>
2981 * error.h, error.c: Added `scm_wrong_type_arg_msg' to support
2982 displaying the expected type. Use SCM_LISTn in a couple places
2983 instead of scm_cons-ing by hand.
2985 * __scm.h: Added SCM_ASSERT_TYPE macro.
2987 * validate.h, scm_validate.h: Added the former, as a renamed
2988 version of the latter with SCM_ASSERT_TYPE used in
2989 SCM_MAKE_VALIDATE (instead of just SCM_ASSERT)
2991 * Makefile.am: Rename scm_validate.h to validate.h.
2993 * *.c, *.h: Include validate.h, not scm_validate.h (old name's
2994 prefix was superfluous).
2996 Thu Mar 2 15:33:12 2000 Greg J. Badros <gjb@cs.washington.edu>
2998 * hashtab.c: Improved documentation for lots of functions. Added
2999 handwritten docs for `hash-fold'.
3001 Thu Mar 2 15:13:25 2000 Greg J. Badros <gjb@cs.washington.edu>
3003 * list.c: Added hand-written docs for `del{q,v,ete}1!'.
3005 Thu Mar 2 12:38:30 2000 Greg J. Badros <gjb@cs.washington.edu>
3007 * list.c: Moved append docs to append! Thanks Dirk Hermann. Also,
3008 added append docs from R4RS.
3010 * strings.c: Docstring typo fix, + eliminate unneeded IMP tests.
3011 Thanks Dirk Hermann!
3013 * chars.h: Provide SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR and
3014 deprecate SCM_ICHRP, SCM_ICHR, SCM_MAKICHR. Thanks Dirk Hermann!
3016 * *.h, *.c: Use SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR throughout.
3017 Drop use of SCM_P for function prototypes... assume an ANSI C
3018 compiler. Thanks Dirk Hermann!
3020 Sat Feb 19 12:20:12 2000 Greg J. Badros <gjb@cs.washington.edu>
3022 * ports.c: Made `set-port-column!' and `set-port-line!' each
3023 return SCM_UNSPECIFIED instead of a (not-scheme-object) integer
3024 that caused a seg fault. Also fixed `set-port-column!'s
3025 docstring. Thanks Han-Wen Nienhuys for finding the bug!
3027 Sun Feb 13 19:11:42 2000 Greg J. Badros <gjb@cs.washington.edu>
3029 * arbiters.c, eq.c, gc.c, guardians.c, list.c, ports.c, print.c,
3030 regex-posix.c, scmsigs.c, stime.c, strings.c, variable.c, stime.c,
3031 strings.c, variable.c: Added lots of documentation, cleaned up
3032 some existing documentation. Occasionally changed formal params
3033 to match docs. Also folded an #ifdef into the inners of a
3034 primitive instead of having two copies of the primitive
3035 (`get-internal-real-time', from stime.c)
3037 Sun Feb 13 18:12:19 2000 Greg J. Badros <gjb@cs.washington.edu>
3039 * ports.c: Added docs for primitives missing them. Written by
3042 Sun Feb 13 09:40:36 2000 Greg J. Badros <gjb@cs.washington.edu>
3044 * guile-doc-snarf.in: Use ${AWK} -f guile-func-name-check, not
3045 just execing guile-func-name-check. Thanks Michael Livshin!
3047 Thu Feb 10 11:43:23 2000 Greg J. Badros <gjb@cs.washington.edu>
3049 * guile-snarf.awk.in: Tweak to work with Sun/HP awk, removed some
3050 dead code. Patch from Michael Livshin.
3052 * guile-doc-snarf.in: Tweak to work with Sun/HP sh. Patch from
3055 2000-02-09 Gary Houston <ghouston@arglist.com>
3057 * init.c (scm_init_standard_ports): when stdout is a tty, make the
3058 current-output-port unbuffered by default. this is less confusing
3059 for interactive use. it was line-buffered because of a
3060 performance problem with unbuffered ports, but I think it will be
3063 2000-02-08 Gary Houston <ghouston@arglist.com>
3065 * __scm.h: don't define long_long or ulong_long if HAVE_LONG_LONGS
3068 * stime.c (scm_localtime, scm_mktime): if neither HAVE_TM_ZONE nor
3069 HAVE_TZNAME are defined, use an empty string instead of giving two
3070 spurious compile-time errors.
3072 Tue Feb 8 13:57:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3074 * ports.c: Doc patches from Richard Kim. Pasted from MIT Scheme.
3077 Mon Feb 7 09:07:31 2000 Greg J. Badros <gjb@cs.washington.edu>
3079 * macros.c: Doc patches from Richard Kim. Pasted from scm.texi.
3081 Sun Feb 6 20:26:21 2000 Greg J. Badros <gjb@cs.washington.edu>
3083 * pairs.c: Doc patches from Richard Kim. Pasted from MIT Scheme
3084 (which is GNU GPL'd).
3086 2000-01-31 Gary Houston <ghouston@arglist.com>
3088 * strings.h: don't use SCM_P. don't include <string.h>.
3089 * error.c, gh_data.c, ports.c, script.c, strop.c: include <string.h>.
3091 * strings.c (scm_string_ref): make the 2nd argument compulsory.
3092 previously it defaulted to zero for no good reason that I can see.
3093 use a local variable for SCM_INUM (k). replace
3094 SCM_VALIDATE_INUM_DEF with SCM_VALIDATE_INUM_COPY.
3096 (scm_makfromstr): cosmetic changes.
3098 (scm_string): Accept only chars in the list, not strings, for
3099 conformance to R5RS (particularly for list->string, which is
3100 supposed to be the inverse of string->list.) remove
3101 SCM_DEFER_INTS/SCM_ALLOW_INTS, which is unnecessary since
3102 scm_makstr handles the cell allocation. when reporting wrong-type
3103 arg, don't report the position as 1.
3105 * posix.c (scm_init_posix): intern PIPE_BUF if it's defined.
3107 2000-01-29 Gary Houston <ghouston@arglist.com>
3109 * posix.c (scm_pipe): rewrote the docstring.
3111 * filesys.c (scm_select, retrieve_select_type, get_element,
3112 fill_select_type, set_element): modified so that Scheme
3113 "select" tests port buffers for the ability to provide input
3114 or accept output. Previously only the underlying file descriptors
3115 were checked. Rewrote the docstring.
3117 Thu Jan 27 10:14:25 2000 Greg J. Badros <gjb@cs.washington.edu>
3119 * vectors.c, symbols.c, strorder.c: Documentation cut and pasted
3120 from Gregg Reynolds. Thanks Gregg!
3122 Thu Jan 27 09:59:38 2000 Greg J. Badros <gjb@cs.washington.edu>
3124 * strop.c (scm_i_index): Obfuscated commented-out SCM_DEFINE by
3125 adding "x" prefix to the line so that guile-func-name-check
3126 doesn't complain unnecessarily.
3128 Wed Jan 26 17:33:52 2000 Greg J. Badros <gjb@cs.washington.edu>
3130 * throw.c: Factor out an #ifdef/#else/#endif choice more finely
3131 for maintainability.
3133 * strop.c: Documentation added by Gregg A. Reynolds. Pasted in
3136 Wed Jan 26 10:02:11 2000 Greg J. Badros <gjb@cs.washington.edu>
3138 * tag.c: Added doc for `tag', but mark as deprecated since Mikael
3139 suggests removing tag.c altogether (and using a new `class-of'
3142 * strings.c: Added documentation from Gregg A. Reynolds. Edited
3143 a bit by me to use FOO instead of @var{foo} and to have the
3144 summary come before preconditions on input. Also dropped trailing
3147 * gsubr.c: Do not use SCM_DEFINE for `gsubr-apply'. Register the
3148 function with scm_make_subr_opt w/ last arg of 0 so it is not
3149 visible at the Scheme level. Mikael says that this is the right
3150 thing because the first arg to the proc is the guts of a compiled
3151 closure and shouldn't be exposed to the Scheme level.
3153 Tue Jan 25 17:15:47 2000 Greg J. Badros <gjb@cs.washington.edu>
3155 * sort.c: typo in comment fixed.
3157 * keywords.c: Added documentation.
3159 * guardians.c: Added documentation (could be better).
3161 * gc.c: Added docs for gc-set-debug-check-freelist.
3163 * eq.c: Added docs for eq?, eqv? equal? abridged from R4RS.
3165 * boolean.c: Added docs for `not', `boolean?' (by hand).
3167 Tue Jan 25 13:28:56 2000 Greg J. Badros <gjb@cs.washington.edu>
3169 * random.c: Added documentation, from SLIB page:
3170 http://angela.ctrl-c.liu.se/~calle/scheme/slib_toc.html
3172 Mon Jan 24 17:50:20 2000 Greg J. Badros <gjb@cs.washington.edu>
3174 * variable.c, version.c: Added documentation, written by hand
3175 since I could not find anything already written that was
3178 2000-01-23 Gary Houston <ghouston@arglist.com>
3180 * filesys.c (scm_chown): omit port/fdes support if HAVE_FCHOWN is
3181 not defined (thanks to Richard Y. Kim).
3183 Thu Jan 20 13:00:38 2000 Greg J. Badros <gjb@cs.washington.edu>
3185 * Makefile.in: Removed, this is auto-generated.
3187 Thu Jan 20 11:33:47 2000 Dirk Hermann <dirk@ida.ing.tu-bs.de> --applied 01/20/00 gjb
3189 * list.c: Put some variable initialization code at the point of
3190 declaration; Added a comment for list*; Formatting changes.
3192 * load.c: use SCM_NNULLP to make sure the end of a list is not
3195 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3197 * backtrace.c (scm_display_error_message): Bugfix: Don't use
3198 result of scm_list_p as C boolean.
3199 (scm_display_error_message, scm_set_print_params_x): Use new
3200 validation macros. (Thanks to Dirk Herrmann.)
3202 * net_db.c (scm_resolv_error): Cast result from hstrerror.
3204 * strports.c (st_end_input): Inserted parenthesis to get operator
3207 * list.h (scm_init_list): Removed SCM_P around prototypes.
3209 * fports.c, list.c, numbers.c, ports.c, stime.c, symbols.c,
3210 filesys.c, posix.c: Converted docstrings to ANSI C format and
3211 escaped " occurring inside string literals.
3213 Tue Jan 18 13:21:08 2000 Mikael Djurfeldt <mdj@r11n07-s.pdc.kth.se>
3215 * posix.c (scm_mknod): Escape " occuring inside docstring.
3217 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3219 * alist.c, chars.c, debug.c, dynl.c, dynwind.c, error.c, eval.c,
3220 evalext.c, filesys.c, gc.c, hash.c, hashtab.c, ioext.c,
3221 keywords.c, list.c, load.c, macros.c, net_db.c, numbers.c,
3222 objprop.c, ports.c, posix.c, print.c, procprop.c, procs.c,
3223 ramap.c, regex-posix.c, root.c, scmsigs.c, simpos.c, socket.c,
3224 stacks.c, stime.c, strings.c, strop.c, strports.c, struct.c,
3225 symbols.c, throw.c, unif.c, vectors.c, version.c, vports.c,
3226 weaks.c: Converted docstrings to ANSI C format.
3228 * filesys.c (scm_chmod), simpos.c (scm_system), version
3229 (scm_version), vports (scm_make_soft_port): Escape " occuring
3232 Mon Jan 17 11:41:22 2000 Greg J. Badros <gjb@cs.washington.edu>
3234 * scm_validate.h: Added SCM_VALIDATE_ULONG_COPY,
3235 SCM_VALIDATE_LONG_COPY
3237 * numbers.c: Use SCM_VALIDATE_ULONG_COPY, instead of
3238 SCM_VALIDATE_INUM_COPY to let bigger numbers be used. Rename a
3239 couple of formal arguments (and fix their uses) to make arguments
3240 match the documentation.
3242 2000-01-14 <mstachow@alum.mit.edu>
3244 * Makefile.am: Augment path when running guile-doc-snarf so
3245 guile-func-name-check is found.
3247 Fri Jan 14 09:34:55 2000 Greg J. Badros <gjb@cs.washington.edu>
3249 * scm_validate.h (SCM_NUM2LONG_DEF): Fix this macro to just use
3250 def, not SCM_MAKINUM(def); thanks Janis Bzerins!
3252 Wed Jan 12 00:06:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3254 * net_db.c (s_scm_inet_makeaddr): Use SCM_NUM2ULONG since that's
3255 the way guile-1.3.4 worked, but #if 0 out the version using
3256 SCM_VALIDATE_INUM_COPY for stricter testing.
3258 Tue Jan 11 18:24:18 2000 Greg J. Badros <gjb@cs.washington.edu>
3260 * guile-doc-snarf.in: Use new $fullfilename for running
3261 guile-func-name-check, and put "$fullfilename" and "$filename" in
3262 quotes at uses to make sure re-splitting on whitespace does not
3263 occur (so filenames w/ embedded whitespace would work okay, though
3264 I sure hope we never have to deal with that! :-) ). Thanks to
3265 Mikael for pointing out the source_dir != build_dir was broken.
3267 Tue Jan 11 17:42:40 2000 Greg J. Badros <gjb@cs.washington.edu>
3269 * scm_validate.h: Added SCM_NUM2LONG_DEF macro. Make
3270 SCM_OUT_OF_RANGE use SCM_MAKINUM, not scm_long2num. Added
3271 SCM_COERCE_ROSTRING macro. Added SCM_VALIDATE_NONEMPTYLIST
3272 macro. Fix SCM_VALIDATE_STRINGORSUBSTR macro to not use SLOPPY
3275 * ports.c (scm_port_closed_p): Validate that the arg is a PORT,
3276 then return whether it's an open port (was validating that it was
3277 an open port -- this was a bug I introduced back in December, but
3278 my careful reading of diffs caught it).
3280 * numbers.c: Recombine the two conditional-compilation paths for
3281 all the log* primitives -- they were split based on #ifndef
3282 scm_long2num; factored out a SCM_LOGOP_RETURN macro, and fixed
3283 some bugs and inconsistencies in the two sets of implementations.
3284 (scm_lognot) Fixed *atrocious* re-use of a SCM as an integer!
3286 * ioext.c: Use SCM_ASSERT_RANGE in a couple places, and
3287 SCM_VALIDATE_INUM_COPY once where it should've been used.
3289 * fluids.c (scm_internal_with_fluids): Use
3290 SCM_VALIDATE_LIST_COPYLEN.
3292 * filesys.c: Use SCM_NUM2LONG instead of SCM_VALIDATE_INUM_COPY;
3293 this is questionable as it relaxes type safety, but other changes
3294 were useful and all SCM_NUM2LONG's should probably be
3295 revisited. Use SCM_OUT_OF_RANGE, SCM_WRONG_TYPE_ARG.
3297 * evalext.c: line-break change on 1 line.
3299 * eval.c (nconc2last): Takes a non-empty list as its first
3300 argument, not just a list.
3302 * dynl.c: Use new SCM_COERCE_ROSTRING macro.
3304 Tue Jan 11 15:44:23 2000 Greg J. Badros <gjb@cs.washington.edu>
3306 * dynl.c, feature.c, filesys.c, fports.c, list.c, load.c,
3307 net_db.c, sort.c, stacks.c, unif.c: Use SCM_WTA, SCM_MISC_ERROR
3310 * symbols.c (scm_sysintern0): Fixed the function name in a
3311 scm_misc_error invocation.
3313 * print.c (scm_simple_format): Do not need SCM_COERCE_SUBSTR, and
3314 use scm_return_first to ward off latent GC bug that Mikael caught.
3316 * async.c: Use SCM_VALIDATE_ASYNC_COPY one place where it wasn't
3317 used before but should've been.
3319 2000-01-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3321 * snarf.h (SCM_PROC1): Replaced SCM (*) (...) with
3322 SCM_FUNC_CAST_ARBITRARY_ARGS.
3324 Tue Jan 11 13:44:07 2000 Greg J. Badros <gjb@cs.washington.edu>
3326 * guile-func-name-check.in: Added this script to statically check
3327 #define FUNC_NAME, #undef FUNC_NAME in the source.
3329 * sort.c, posix.c: Fix #undef FUNC_NAME lines to not have trailing
3330 redundant comment, semicolon; caught by new guile-func-name-check
3333 * debug.c: Fix mistaken #define FUNC_NAME for scm_make_iloc.
3334 Caught by new guile-func-name-check-script.
3336 * Makefile.am: Added guile-func-name-check to bin_SCRIPTS
3338 * ramap.c: Fix #if 0'd out code to be syntactically acceptable to
3339 guile-func-name-check.
3341 * guile-doc-snarf.in: Run guile-func-name-check on the file before
3344 Tue Jan 11 11:31:10 2000 Greg J. Badros <gjb@cs.washington.edu>
3346 * fports.c, ports.c, ports.h, strports.c, vports.c: Make write
3347 port function take const void*, not void*.
3349 Tue Jan 11 11:18:07 2000 Greg J. Badros <gjb@cs.washington.edu>
3351 * scm_validate.h, chars.c, ports.c, print.c, read.c, strings.c,
3352 strop.c: Use SCM_VALIDATE_ICHR, SCM_VALIDATE_ICHR_COPY instead of
3353 SCM_VALIDATE_CHAR, SCM_VALIDATE_CHAR_COPY. Change made for
3354 consistency with the other macros dealing with immediate
3355 characters. (Similar to INT -> INUM change a week or so ago).
3357 Tue Jan 11 10:41:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3359 * dynl.c, error.c, eval.c, feature.c, filesys.c, fports.c, list.c, load.c,
3360 net_db.c, read.c, socket.c: Update error messages to use ~A for
3361 %s, ~S for %S to work with new `simple-format' format and be
3362 standardized better.
3364 * print.h, print.c (scm_simple_format): Added `simple-format'
3365 primitive. It's the old scm_display_error, with ARGS now a rest
3366 parameter, and the destination first instead of last (and a couple
3367 new capabilities inspired by `format' -- #t as destination means
3368 current-output-port, #f means return the formatted text as a
3371 * gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
3373 * backtrace.c (scm_display_error_message): Rewrote to use
3374 scm_simple_format() procedure.
3376 * __scm.h: Added commented-out #define of GUILE_DEBUG_FREELIST
3378 2000-01-09 Marius Vollmer <mvo@zagadka.ping.de>
3380 Finally applied the libltdl patch from Thomas Tanner, with slight
3383 * DYNAMIC-LINKING: Removed because it is obsolete.
3384 * dynl.c: Use ANSI prototypes.
3385 (sysdep_dynl_link): Use lt_dlopenext instead of lt_dlopen.
3386 * scmconfig.h.in: Do not change, as it is automatically generated.
3388 1999-07-25 Thomas Tanner <tanner@ffii.org>
3390 * dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c: deleted
3392 * Makefile.am: likewise, add INCLTDL (libltdl headers) to
3393 INCLUDES, set dlpreopened files in LDFLAGS, link libguile
3395 * dynl.c: use libltdl if DYNAMIC_LINKING is enabled,
3396 * guile.c: register preloaded modules
3397 * scmconfig.h.in: remove obsolete symbols
3399 2000-01-09 Gary Houston <ghouston@arglist.com>
3401 * These changes should make it unnecessary to call tzset from
3402 Scheme after modifying the TZ environment variable, even if the
3403 system date facilities cache the value.
3404 * stime.c (setzone, scm_localtime): added comments.
3405 (tzset): don't define a noop tzset macro if HAVE_TZSET not defined.
3406 (setzone): don't call tzset.
3407 (restorezone): call tzset only if HAVE_TZSET is defined.
3408 (scm_tzset): don't define if HAVE_TZSET not defined. Change the
3409 doc string to indicate that this procedure isn't likely to do
3411 (scm_localtime, scm_strftime, scm_mktime): call tzset if
3412 LOCALTIME_CACHE is defined.
3414 2000-01-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3416 * posix.c (scm_sync): Return SCM_UNSPECIFIED.
3418 2000-01-09 Gary Houston <ghouston@arglist.com>
3420 * eval.c: define scm_unbound_variable_key ('unbound-variable).
3421 scm_lookupcar1: throw an error with key 'unbound-variable instead
3422 of 'misc-error when an unbound variable is encountered.
3424 * filesys.c (scm_mkdir, scm_rmdir, scm_getcwd, scm_select,
3425 scm_symlink, scm_readlink, scm_lstat),
3426 posix.c (scm_setpgid, scm_setsid, scm_ctermid, scm_tcgetpgrp,
3427 scm_tcsetpgrp, scm_uname, scm_setlocale, scm_mknod, scm_nice,
3429 simpos.c (scm_system),
3430 stime.c (scm_times, scm_strptime):
3431 move the HAVE_XXX feature tests out of the procedure bodies.
3432 don't use SCM_SYSMISSING.
3433 scm_validate.h (SCM_SYSMISSING): removed.
3434 error.h, error.c (scm_sysmissing): comment that this is deprecated.
3435 see ChangeLog entry for 1999-12-28.
3437 Sat Jan 8 19:52:04 2000 Greg J. Badros <gjb@cs.washington.edu>
3439 * scm_validate.h (SCM_VALIDATE_BOOL_COPY): Fix typo.
3441 Sat Jan 8 17:06:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3443 * backtrace.c: Fix spelling typo in a comment.
3445 * snarf.h: Use new SCM_DOCS macro to encapsulate the non SCM_INIT
3446 text. Reformatted some of the expansions.
3448 Fri Jan 7 15:50:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3450 * scm_validate.h (SCM_OUT_OF_RANGE): Use scm_out_of_range_pos to
3451 report the position of the argument.
3453 * error.h, error.c (scm_out_of_range_pos): Added this function to
3454 take extra "pos" argument, the position number of the errant
3457 * debug.c: Use SCM_OUT_OF_RANGE instead of scm_out_of_range.
3459 * snarf.h: Use SCM_HERE and SCM_INIT as names, not SCM_NOTSNARF
3460 and SCM_SNARFING. Also put the %%% in the SCM_INIT since Mikael
3461 prefers that and I'm reasonably indifferent.
3463 Fri Jan 7 15:03:32 2000 Greg J. Badros <gjb@cs.washington.edu>
3465 * snarf.h: Factor out differences between C++ and non-C++ into
3466 SCM_FUNC_CAST_ARBITRARY_ARGS macro. Modify all the snarf macro
3467 definitions to use SCM_NOTSNARF and SCM_SNARFING macros (like
3468 Mikael's macros, below, but changed names and SCM_SNARFING no
3469 longer expands to include %%% -- that must appear in the argument
3470 so that the token appears at the call-site as a reminder).
3472 2000-01-07 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3474 * snarf.h (SCM_INSITU, SCM_INIT): New snarf macros for use in user
3475 snarf macro definitions.
3477 2000-01-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3479 * chars.c (scm_integer_to_char): Use Greg's nice
3480 SCM_VALIDATE_INUM_RANGE macro for argument checking for closer
3483 Thu Jan 6 11:48:49 2000 Greg J. Badros <gjb@cs.washington.edu>
3485 * *.c, snarf.h: Replace GUILE_PROC1 with SCM_DEFINE1 throughout.
3487 Thu Jan 6 11:22:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3489 * Makefile.am (ETAGS_ARGS): Switch to SCM_DEFINE, SCM_DEFINE1
3490 instead of GUILE_PROC.
3492 Thu Jan 6 11:21:49 2000 Greg J. Badros <gjb@cs.washington.edu>
3494 * alist.c: Do not report mismatch errors on some uses of `tmp' (do
3495 this by using SCM_ARG2 instead of `2' in the SCM_VALIDATE_CONS
3498 Thu Jan 6 09:54:33 2000 Dirk Herrmann <dirk@ida.ing.tu-bs.de> --gjb applied
3500 * scm_validate.h: Remove some redundant NIMP tests.
3502 * alist.c: minimize scope of the tmp variables, and initialize
3503 them when declared. The strange SCM_NIMP tests are replaced by
3504 SCM_CONSP tests that more closely reflect the intended semantics.
3505 However, we don't get a performance penalty here, because the
3506 SCM_CONSP test was performed by the ALISTCELL test anyway. * The
3507 extremely ugly use of ASRTGO macros was removed: The calls to
3508 ASRTGO were not encapsulated by "#ifndef SCM_RECKLESS", but got a
3509 label parameter that only exists when SCM_RECKLESS is not defined.
3510 This works, because ASRTGO itself is defined in a way that it only
3511 makes use of the label parameter if SCM_RECKLESS is not defined
3512 (shudder!). Does guile make at all use of the possibility to
3513 define SCM_RECKLESS? * Codesize is likely to be reduced, since
3514 instead of two calls to SCM_ASSERT performed by the ALISTCELL test
3515 we now only get one test.
3517 * list.c: Use SCM_NNULLP, not SCM_NIMP as appropriate. Also use
3518 SCM_NULLP instead of SCM_IMP. Drop use of "register" keyword on
3519 some variables in `list?'. Fix `reverse' and `reverse!'
3520 primitives to handle improper lists better.
3522 Wed Jan 5 11:24:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3524 * *.[ch]: Whitespace changes -- added space after SCM_VALIDATE_*
3525 macros and SCM_DEFINE macros to match GNU coding standards.
3527 Wed Jan 5 11:04:24 2000 Greg J. Badros <gjb@cs.washington.edu>
3529 * *.[ch]: Replace GUILE_PROC w/ SCM_DEFINE.
3531 Wed Jan 5 10:59:06 2000 Greg J. Badros <gjb@cs.washington.edu>
3533 * *.[ch]: Replace SCM_VALIDATE_INT w/ SCM_VALIDATE_INUM for
3534 better consistency with the names of other SCM_VALIDATE_ macros
3535 and better conformance to guile naming policy.
3537 Wed Jan 5 10:50:39 2000 Greg J. Badros <gjb@cs.washington.edu>
3539 * ports.c (s_scm_close_all_ports_except): Use SCM_ARG1 in a
3540 SCM_VALIDATE instead of 1 to avoid a check on the argument (since
3541 it's not the actual name of the formal).
3543 * guile-snarf.awk.in: Do argument/number mismatch checking and
3544 print warnings in an Emacs compile-mode parseable format.
3546 * struct.c: Use SCM_ASSERT_RANGE instead of SCM_ASSERT w/
3547 SCM_OUTOFRANGE as 3rd argument.
3549 * random.c: Fix argument/number mismatch (that I introduced :-( ).
3551 * __scm.h: Do not #define SCM_ARG* when snarfing;
3552 lets us distinguish between 1 and SCM_ARG1 when snarfing as only
3553 the former (using the number) requires the argument to match the
3554 formal in the current argument snarfing check.
3556 * snarf.h: Give new definition of SCM_ASSERT when in
3557 snarfing mode to output a lexically-identifiable sequence that the
3558 guile-snarf.awk script uses to verify argument/position matching.
3560 * ramap.c: Remove extraneous #undef FUNC_NAME.
3562 Wed Jan 5 08:36:38 2000 Greg J. Badros <gjb@cs.washington.edu>
3564 * guile-doc-snarf.awk.in: Removed -- guile-snarf.awk.in is the
3565 current version of the same functionality; it writes the .x output
3566 to stdout instead of directly into the file.
3568 Wed Jan 5 08:15:04 2000 Greg J. Badros <gjb@cs.washington.edu>
3570 * unif.c, symbols.c, strings.c, stacks.c, random.c, print.c,
3571 posix.c: Eliminated a bunch of SCM_NIMP(..)s that are now
3572 redundant with the safer macros. Patch from Dirk Hermann applied
3573 by hand. Thanks Dirk!
3575 * scm_validate.h: Added SCM_VALIDATE_VECTOR_OR_DVECTOR for some
3578 * ramap.c: whitespace change.
3580 Tue Jan 4 14:21:35 2000 Greg J. Badros <gjb@cs.washington.edu>
3582 * options.c, objects.c, keywords.c, gc.c: Some redundant SCM_NIMP
3583 removals from Dirk Hermann.
3585 * alist.c: Rename formals to match the parameter names in the
3586 documentation, updates to documentation. Thanks Dirk Hermann!
3588 2000-01-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3590 * eval.c (SCM_CEVAL): Reverse order of
3591 scm_stack_checking_enabled_p and SCM_STACK_OVERFLOW_P
3592 (Thanks to Brad Knotwell.)
3594 Mon Jan 3 08:30:02 2000 Greg Harvey <Greg.Harvey@thezone.net> (applied --01/03/00 gjb)
3596 * gc.c (scm_debug_newcell): Added SCM_SETCAR of the newly
3599 * pairs.h: Added a comment about the need for the SCM_SETCAR in
3602 Mon Jan 3 08:25:19 2000 Greg J. Badros <gjb@cs.washington.edu>
3604 * dynl-vms.c, debug.c, coop-threads.c, backtrace.c, eval.c: More
3605 SCM_NIMP tests that were redundant are now eliminated. Patches
3606 from Dirk Hermann applied by hand.
