1 2000-08-26 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
3 * gdbint.c (gdb_print): Removed superfluous macro definition.
5 * objects.c (scm_init_objects), print.c (scm_init_print), struct.c
6 (scm_init_struct): First arg to scm_make_vtable_vtable should be a
7 string, not a symbol. (`make-vtable-vtable' needs to append this
8 string to another string and then pass it through
11 * stacks.c (scm_init_stacks): Pass a string, not a layout object,
12 to scm_make_vtable_vtable. (Thanks to Dale P. Smith.)
14 * struct.c (scm_make_struct_layout): Removed reference to
15 "read-only string" in comment; Check that argument is a string.
16 (scm_make_vtable_vtable): Check that argument is a string.
18 * environments.c (scm_init_environments): All internal includes in
19 libguile must use the prefix "libguile/" in path names since inly
20 the top-level source directory is on the include list. (That, in
21 turn, is because we want to distinguish between system header
22 files and hedares files internal to libguile.)
24 * strings.c (scm_make_shared_substring, scm_read_only_string_p):
26 (scm_string_length, scm_string_ref, scm_substring,
27 scm_string_append): Don't accept symbols as arguments (R5RS).
29 2000-08-25 Neil Jerram <neil@ossau.uklinux.net>
31 * ports.c (scm_set_port_column_x): Fix docstring so that it
32 mentions set-port-line! rather than set-port-column! twice.
34 * guardians.c (scm_make_guardian): Remove spurious . from doc string.
36 2000-08-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
38 * Makefile.am: Added all necessary environments.* files.
40 * init.c: Include environments.h.
42 (scm_boot_guile_1): Initialize the environments.
44 * environments.[ch]: Added. Most of the credit for these files
45 goes to Jost Boekemeier.
47 2000-08-25 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
49 * procprop.c: #include "libguile/smob.h"; handle applicable smobs.
51 2000-08-24 Keisuke Nishida <kxn30@po.cwru.edu>
53 * smob.h (scm_smob_descriptor): Added `apply' and `gsubr_type'.
54 * smob.c (scm_make_smob_type): Initialize `apply' and `gsubr_type'.
55 (scm_set_smob_apply): New function.
56 (scm_smob_apply_0, scm_smob_apply_1, scm_smob_apply_2,
57 scm_smob_apply_3): New functions.
58 * eval.c (SCM_CEVAL, SCM_APPLY): Added dispatch for applicable smobs.
59 * procs.c (scm_procedure_p): Check applicable smobs.
61 2000-08-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
63 * Makefile.am (BUILT_SOURCES): Experimentally added scmconfig.h
64 also here. (This is supposed to make sure that scmconfig.h is
65 built before all sources in order to prevent that everything has
66 to be rebuilt again. Hope it works---I'm just guessing. :)
68 * fluids.c (scm_fluid_set_x): Return SCM_UNSPECIFIED.
70 2000-08-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
72 * gc.c (scm_gc_mark): Don't use GUILE_DEBUG flag to compile in
73 extra tests. (GUILE_DEBUG is only supposed to make extra
74 debugging functions available.)
76 2000-08-21 Michael Livshin <mlivshin@bigfoot.com>
78 * gc.h (SCM_GC_CARD_N_CELLS): change to be a nice non-confusing
81 2000-08-19 Michael Livshin <mlivshin@bigfoot.com>
83 * gc.c (scm_gc_sweep): added a `continue' statement that have
84 fallen through the cracks in the merge. thanks to Shuji Narazaki!
86 * gc.h: removed some stuff that broke compilation for people and
87 wasn't actually needed anyway.
89 2000-08-18 Neil Jerram <neil@ossau.uklinux.net>
91 * filesys.c (scm_fcntl): Docstring fix - missing newlines inserted.
93 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_sethost,
94 scm_setnet, setproto, setserv): Argument names changed to match
97 * feature.c (scm_program_arguments): New docstring.
99 * simpos.c (scm_getenv): Reflow docstring.
101 * eq.c (scm_eq_p, scm_eqv_p, scm_equal_p): Add texinfo markup to
104 * chars.c (scm_char*): Docstring fixes - texinfo markup.
106 2000-08-18 Neil Jerram <neil@ossau.uklinux.net>
108 * boolean.c (scm_not, scm_boolean_p): Docstring fixes - add
109 texinfo markup and remove trailing newlines.
111 2000-08-17 Michael Livshin <mlivshin@bigfoot.com>
113 this changes the Guile GC to use cards (aka "chunklets").
114 (most of the ideas and some of the code are by Greg Harvey, though
115 the code is probably unrecognizable now. the original chunklet
116 proposal, way back, is by Dale Jordan).
118 * tags.h: (SCM_GCTYPE16, SCM_GCCDR, SCM_GC[8]MARKP,
119 SCM_SETGC[8]MARK, SCM_CLRGC[8]MARK): moved from here into gc.h.
120 some (most) of these are probably going to be deprecated.
122 * gc.h (SCM_MARKEDP): simplified, there are no different mark bit
124 (SCM_GC_CARD_*, SCM_C_BVEC_*): lots of new macros to deal with
125 cards and bvecs (bit-vectors).
127 * gc.c: (scm_default_init_heap_size_*): defined to take cards into
128 account, but keeping more or less the same values as previously.
129 added some simple helper macros.
130 (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK): defined to take cards
132 (BVEC_*, scm_mark_space_t, current_mark_space, mark_space_ptr,
133 current_mark_space_offset, mark_space_head, get_bvec,
134 clear_mark_space): new functions and supporting variables, types
135 and macros that implement mark space management.
136 (scm_igc): clear the mark space (all of it) before beginning the
138 (scm_gc_mark): changed the tests for rogue cells, much simplified
139 throughout (no different mark bit locations to worry about now).
140 (scm_mark_locations): don't consider card header cells.
142 (scm_gc_sweep): simplified.
143 (init_heap_seg): changed to take cards into account.
145 2000-08-16 Michael Livshin <mlivshin@bigfoot.com>
147 * stime.c (scm_c_get_internal_run_time): new function, same as
148 scm_get_internal_run_time but returns a long. it's used by the GC
149 for timekeeping, since with scm_get_internal_run_time there is a
150 (extremely theoretical) possibility of consing.
151 (scm_get_internal_run_time): redefined in terms of
152 scm_c_get_internal_run_time.
154 * stime.h: added prototype for scm_c_get_internal_run_time.
156 * gc.c (scm_gc_stats): add more obscure stats, such as: mark time,
157 sweep time, total marked cells, total swept cells, and number of
158 times GC was invoked.
159 (gc_start_stats): renamed from scm_gc_start, made static, taught
160 to init the new stats.
161 (gc_end_stats): renamed from scm_gc_end, made static, taught to
162 calculate the new stats.
163 (scm_igc): don't call gc_start_stats unless we are sure that we
164 are indeed going to collect. also, added some timekeeping between
165 the mark and sweep phases.
166 (scm_gc_sweep): count number of cells we sweep as we go.
168 * gc.h: removed prototypes for scm_gc_{start,end}.
170 2000-08-13 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
172 * alist.c (scm_assq, scm_assv, scm_assoc): Report argument type
173 error for the alist rather than the sublist where the type
174 mismatch is discovered.
176 2000-08-13 Neil Jerram <neil@ossau.uklinux.net>
178 * root.c (s_scm_call_with_dynamic_root): Docstring fix - rogue
181 2000-08-12 Neil Jerram <neil@ossau.uklinux.net>
183 * numbers.c (scm_ash): Docstring fix - missing newlines.
185 * ports.c (scm_port_filename): Docstring fix - missing newline.
187 * strports.c (scm_eval_string): Docstring fix - missing newline.
189 * vports.c (s_scm_make_soft_port): Docstring updated so that
192 * strop.c: Docstring fixes - quotation marks and backslashes
195 * numbers.c (s_scm_logand): Docstring fix - "@end lisp" inserted.
197 2000-08-11 Neil Jerram <neil@ossau.uklinux.net>
199 * macros.c: Remove surplus newlines from end of docstrings.
201 * list.c (scm_list_tail): Add @deffnx line to docstring for
204 * keywords.c: Docstring improvements in conjunction with new
205 reference manual doc on keywords.
207 * error.c (scm_error_scm): Fix texinfo syntax error in
208 docstring. (@code(~S) should be @code{~S}.)
210 * dynl.c: Remove surplus newlines from end of docstrings.
212 2000-08-11 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
214 * eval.c (scm_eval): Backward incompatible change: Now takes an
215 environment specifier as second arg. `eval' hereby becomes R5RS
217 (scm_i_eval_x, scm_i_eval): New functions (replace
219 (scm_eval2, scm_eval_3): Deprecated.
220 (scm_top_level_lookup_closure_var): Deprecated.
222 * eval.h: #include "struct.h".
224 * evalext.c (scm_definedp): Have to work before module system is
227 * modules.h (SCM_MODULEP, SCM_VALIDATE_MODULE,
228 SCM_MODULE_OBARRAY, SCM_MODULE_USES, SCM_MODULE_BINDER,
229 SCM_MODULE_EVAL_CLOSURE): New macros.
230 (scm_module_index_obarray, scm_module_index_uses,
231 scm_module_index_binder, scm_module_index_eval_closure): New
232 constants; #include "validate.h".

236 (scm_post_boot_init_modules): Initialize scm_module_tag.
237 (scm_interaction_environment): New primitive.
239 * symbols.c (scm_can_use_top_level_lookup_closure_var): Removed.
240 #include "modules.h".
242 * strports.c (scm_eval_string): Evaluate in
243 scm_interaction_environment ().
245 * script.c (scm_shell): Pass scm_the_root_module () as second arg
248 * load.c (load): Use `scm_selected_module' to compute second arg
249 to new scm_i_eval_x; Don't call it if module system hasn't booted.
250 (scm_read_and_eval_x): Deprecated.
251 #include "modules.h".
253 * debug.c (scm_local_eval): Use scm_i_eval and scm_i_eval_x.
254 (scm_start_stack): Use scm_i_eval.
256 * strports.c: #include "modules.h".
258 * print.c (scm_simple_format): Be case-insensitive for ~A and ~S
261 2000-08-09 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
263 The following changes are intended to ensure that struct instances
264 are freed before their vtables. It's optimized for the most
265 common case, which is freeing of struct instances.
267 * gc.c (scm_gc_mark, scm_gc_sweep): Remove vcell = 1 magic.
268 (scm_structs_to_free): New variable.
269 (scm_gc_sweep): Hook up structs to free on the scm_structs_to_free
272 * struct.h (SCM_STRUCT_GC_CHAIN, SCM_SET_STRUCT_GC_CHAIN): New
274 (scm_structs_to_free, scm_struct_prehistory): Declare.
276 * struct.c (scm_make_struct, scm_make_vtable_vtable): Structs
277 handles are now double cells; Initialize SCM_STRUCT_GC_CHAIN to
279 (scm_struct_gc_init, scm_free_structs): New GC C hooks.
280 (scm_struct_prehistory): Install them.
282 * init.c (scm_boot_guile_1): Call scm_struct_prehistory.
284 2000-08-06 Marius Vollmer <mvo@zagadka.ping.de>
286 * read.c (scm_flush_ws): Include filename in error message when it
289 2000-08-05 Marius Vollmer <mvo@zagadka.ping.de>
291 * iselect.c: Include <unistd.h>. Thanks to Bertrand Petit!
293 2000-08-02 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
295 * struct.c (scm_make_struct_layout, scm_make_struct,
296 scm_make_vtable_vtable): Updated documentation.
298 * print.c (scm_simple_format): Bugfix: Coerce port before using
301 2000-07-31 Gary Houston <ghouston@arglist.com>
303 * net_db.c: declare h_errno only if HAVE_H_ERRNO is not defined
304 (thanks to Richard Kim for the bug report).
306 2000-07-30 Marius Vollmer <mvo@zagadka.ping.de>
308 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
309 scm_assoc_remove_x): Use scm_delq1_x instead of scm_delq_x, since
310 using the latter is pointless.
312 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
314 * gc.c (scm_gc_sweep): Renamed local variable from 'free' to
315 'free_struct_data' to avoid confusion with stdlib's 'free'.
317 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
319 * vectors.c (scm_make_vector): Fix the initialization order of
320 the vector such that the type cell is initialized last.
322 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
324 * struct.[ch] (scm_struct_init): Made static. Fixed not to rely
325 on the struct cell to be fully initialized.
327 * struct.c (scm_make_struct, scm_make_vtable_vtable): Fix the
328 initialization order of the struct such that the type cell is
331 2000-07-25 Marius Vollmer <mvo@zagadka.ping.de>
333 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
334 scm_assoc_remove_x): Remove only the first cell with a matching
337 2000-07-24 Marius Vollmer <mvo@zagadka.ping.de>
339 * stime.c (scm_strftime): Recognize a return value of zero from
340 strftime as buffer overflow and take care to detect a valid zero
341 length result regardless. Thanks to David Barts!
343 2000-07-23 Marius Vollmer <mvo@zagadka.ping.de>
345 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
346 scm_assoc_remove_x): Remove all cells whose key is eq, eqv, or
347 equal (respectively) to the argument key, not all cells that are
348 eq, eqv, or equal to the first cell with the argument key. Thanks
351 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
353 * gc.h (SCM_FREE_CELL_CDR, SCM_SET_FREE_CELL_CDR), hooks.c
354 (make_hook), modules.c (OBARRAY, USES, BINDER): Pack and unpack
355 SCM values appropriately.
357 * modules.c (scm_standard_eval_closure): Don't pass an inum to
358 scm_makcclo, but rather a long value.
360 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
362 read.c (scm_lreadrecparen), srcprop.c (scm_set_source_property_x):
363 SCM_SETCDR and SCM_WHASHSET macros don't deliver a return value.
364 Thanks to Han-Wen Nienhuys for the bug report.
366 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
368 * root.[ch] (scm_call_catching_errors): Deprecated.
370 * root.c (scm_init_root): Initialize the root smob type using the
371 standard initialization functions.
373 2000-07-17 Marius Vollmer <mvo@zagadka.ping.de>
375 * eval.c (unmemocopy): Don't rely on V being a list of at least
376 one element. Thanks to Bill Schottstaedt!
378 2000-07-15 Michael Livshin <mlivshin@bigfoot.com>
380 * gc.c (scm_done_free): new.
381 expanded comments about scm_done_malloc.
383 * gc.h: added prototype for scm_done_free
385 2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
387 * gc.h (scm_take_stdin): Removed.
389 * gc.h (SCM_VALIDATE_CELL): Delegate cell checks to function
390 scm_assert_cell_valid to allow extensions to the checking
391 functionality without need to recompile everything.
393 * gc.[ch] (scm_assert_cell_valid, scm_set_debug_cell_accesses_x):
394 Added as conditionally compiled functions for the case that
395 SCM_DEBUG_CELL_ACCESSES is enabled.
397 * gc.c (debug_cells_p): Added to indicate whether compile-time
398 included cell access debugging is run-time enabled.
400 * gc.[ch] (scm_gc_running_p): Added to indicate that scm_igc is
401 being executed. Intended to be used instead of scm_gc_heap_lock
404 * error.c (scm_error), gdbint.c (SCM_GC_P): Use scm_gc_running_p
405 instead of scm_gc_heap_lock.
407 * gc.c (scm_igc): Set scm_gc_running_p to true while running.
409 * gc.c (scm_mark_locations): Don't mark free cells.
411 * weaks.c (scm_scan_weak_vectors): Use SCM_FREE_CELL_P instead of
414 2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
416 * gc.c (scm_mark_locations): Minimized some variable scopes and
417 simplified the code a bit.
419 2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
421 * gc.h (SCM_SET_FREE_CELL_TYPE, SCM_SET_FREE_CELL_CDR,
422 SCM_FREE_CELL_P, SCM_FREE_CELL_CDR): Added since free cells
423 should not be accessed via SCM_C[AD]R. Further, using dedicated
424 macros to access free cells allows all other cell accessing macros
425 to treat acesses to free cells as errors, thus enabling better
426 error checks for cell accesses. SCM_FREE_CELL_P is supposed to
427 replace SCM_FREEP some time.
429 * gc.h (SCM_NEWCELL, SCM_NEWCELL2), gc.c (map_free_list,
430 free_list_length, scm_check_freelist, scm_debug_newcell,
431 scm_debug_newcell2, freelist_length, scm_gc_for_newcell,
432 scm_gc_mark, scm_gc_sweep, init_heap_seg): Only use the dedicated
433 cell accessors when accessing free cells.
435 2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
437 * gc.h (SCM_CELL_WORD, SCM_CELL_OBJECT): Treat the referenced
438 object as const in order to make the compiler warn about code like
439 SCM_CELL_WORD (x, n) = y. Instead, SCM_SET_CELL_WORD (x, n, y)
442 (SCM_CELL_WORD_LOC, SCM_CARLOC, SCM_CDRLOC): Return the address
443 as an address to a non-const object, since these macros are used
444 to allow direct write access to objects.
446 2000-07-07 Dirk Herrmann <D.Herrmann@tu-bs.de>
448 * hashtab.c (scm_hash_fn_create_handle_x): Signal an error if the
449 given hash table has no slots.
451 2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
453 * gc.c (policy_on_error): Added in order to allow alloc_some_heap
454 to react to malloc failures in a context dependent way.
456 (scm_check_freelist): No need to flush streams before abort().
458 (scm_gc_for_newcell): Try to allocate new memory in three phases:
459 grow heap if preferred, if still no memory available collect
460 garbage, if still no memory available grow heap.
462 (heap_segment_table_size): Added to always reflect the actual
463 size of the heap segment table, because scm_n_heap_segs may differ
464 from the heap segment table size.
466 (alloc_some_heap): In case of malloc failure, react according to
467 the new policy_on_error parameter (either return to caller or
468 abort immediately). Further, keep heap_segment_table_size up to
471 (scm_init_storage): Initialize heap_segment_table_size.
473 2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
475 * gh.h: Don't include <stdio.h>. Thanks to Han-Wen Nienhuys for
478 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
480 * __scm.h (SCM_OUTOFRANGE, SCM_NALLOC, SCM_HUP_SIGNAL,
481 SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL, SCM_SEGV_SIGNAL,
482 SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL, SCM_SIG_ORD,
483 SCM_ORD_SIG, SCM_NUM_SIGS): Re-introduce these as deprecated
486 * error.c (scm_wta): Re-introduce dispatching for SCM_OUTOFRANGE
487 and SCM_NALLOC, but as a deprecated feature.
489 2000-06-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
491 * debug.c: Added #include fluids.h.
493 * numbers.c (scm_gr_p, scm_leq_p, scm_geq_p): Turned into
494 primitive generics. (Thanks to Nicolas Neuss.)
496 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
498 * gc.c (alloc_some_heap): Use scm_memory_error to indicate a
499 failed attempt to get additional memory from the system.
501 (scm_gc_for_newcell): Changed the control structure to make the
502 behaviour explicit for the case that gc is not able to free any
505 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
507 * __scm.h (SCM_OUTOFRANGE): Removed.
509 * error.c (scm_wta): Removed sick dispatch code for range
510 errors. (More sick dispatches still to be removed.)
512 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
513 scm_hash_fn_remove_x): Eliminate redundant test for if unsigned
514 value is non-negative. Use scm_out_of_range to signal range
517 * hooks.c (make_hook), unif.c (scm_aind): Use scm_out_of_range to
520 * list.c (scm_list_ref, scm_list_set_x, scm_list_cdr_set_x): Fix
521 error reporting (now uses original input parameter to report wrong
522 type argument errors). Use SCM_OUT_OF_RANGE to report range
523 errors and SCM_WRONG_TYPE_ARG to report type errors.
525 * strings.c (scm_substring): Make range checks for negative
526 values explicit (former behaviour relied on an implicit
527 conversion from signed to unsigned). Don't use SCM_ASSERT for
530 * unif.c (scm_aind, scm_transpose_array, scm_bit_set_star_x,
531 scm_bit_count_star): Use scm_out_of_range to signal range
534 * unif.c (scm_transpose_array, scm_bit_position), vectors.c
535 (scm_vector_ref, scm_vector_set_x, scm_vector_move_left_x,
536 scm_vector_move_right_x): Use SCM_ASSERT_RANGE to check ranges.
538 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
540 * validate.h (SCM_VALIDATE_INUM_MIN_COPY,
541 SCM_VALIDATE_INUM_MIN_DEF_COPY, SCM_VALIDATE_INUM_RANGE_COPY):
542 Perform all range checks based on the input value. The former way
543 of using the value that is assigned to the target variable fails
544 if the assignment to the target variable itself can change the
545 value because of type conversion.
547 (SCM_ASSERT_RANGE): Use scm_out_of_range to signal range errors.
549 2000-06-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
551 * gc.c (scm_gc_for_newcell): Behave gracefully also if scm_igc
552 doesn't yield any new cells. In theory this could happen if all
553 cells allocated with NEWCELL are either in use or conservatively
554 marked and all cluster spine cells are conservatively marked.
557 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
559 * __scm.h (SCM_NALLOC): Removed.
561 * error.c (scm_wta): Removed sick dispatch code for memory
562 errors. (More sick dispatches still to be removed.)
564 * numbers.c (scm_mkbig, scm_adjbig), ports.c (scm_make_port_type),
565 random.c (scm_i_copy_rstate, scm_c_make_rstate), smob.c
566 (scm_make_smob_type), srcprop.c (scm_make_srcprops), vectors.c
567 (scm_vector_set_length_x): Now using scm_memory_error to signal
570 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
572 * __scm.h: Removed some commented code and fixed some comments.
574 (SCM_HUP_SIGNAL, SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL,
575 SCM_SEGV_SIGNAL, SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL,
576 SCM_SIG_ORD, SCM_ORD_SIG, SCM_NUM_SIGS): Removed.
578 * async.c: Removed some commented code.
580 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
582 * gc.c (scm_gc_mark, scm_gc_sweep, scm_must_malloc,
583 scm_must_realloc, scm_must_free, alloc_some_heap): Use the
584 appropriate error signalling function.
586 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
588 * root.h (scm_first_type): Removed.
590 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
592 * gc.c (MIN_GC_YIELD): Removed.
594 2000-06-28 Michael Livshin <mlivshin@bigfoot.com>
596 * gc.c (scm_gc_for_newcell): don't try to do GC if it's blocked,
599 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
601 * async.c (scm_gc_async, scm_gc_vcell, scm_sys_gc_async_thunk):
604 (scm_init_async): Moved initialization for scm_gc_async and
605 scm_gc_vcell to gc.c. Moved initialization of scm_asyncs here
608 * async.h (scm_gc_async): Not globally visible any more.
610 * gc.c (scm_gc_stats): Made callable even from within regions
613 (scm_gc_end): Eliminate the hardcoding of the marking of the
614 scm_gc_async from the gc core.
616 (scm_init_storage): Don't initialize the scm_asyncs list here.
617 This is now done in asyncs.c.
619 (scm_gc_vcell): Moved here from async.c.
621 (gc_async): Renamed from scm_gc_async, moved here from async.c
624 (gc_async_thunk): Renamed from scm_sys_gc_async_thunk and moved
627 (mark_gc_async): New hook function for scm_after_gc_c_hook.
629 (scm_init_gc): Added initialization of scm_gc_vcell and
630 gc_async. Further, add mark_gc_async to scm_after_gc_c_hook.
632 * init.c (scm_boot_guile_1): scm_init_gc requires asyncs to be
635 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
637 * gc.c (scm_igc): Removed commented code that once was intended
638 to unprotect struct types with no instances.
640 * root.h (scm_type_obj_list): Removed.
642 2000-06-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
644 * async.c (scm_init_async): Switch to standard way of smob
647 2000-06-21 Michael Livshin <mlivshin@bigfoot.com>
649 * guile-doc-snarf.in: use cut instead of sed, that's much much
650 faster. also, don't call basename more than needed. and, to gain
651 a couple of microseconds more, don't call cat needlessly. (thanks
654 2000-06-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
656 * guile-snarf.awk.in, guile-snarf.in, snarf.h: Rename SCM__I to
657 SCM_SNARF_INIT_START, SCM__D to SCM_SNARF_DOC_START, SCM__S to
658 SCM_SNARF_DOCSTRING_START and SCM__E to SCM_SNARF_DOCSTRING_END.
660 2000-06-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
662 * eval.c, eval.h (scm_top_level_lookup_closure_var): Added.
663 #include "libguile/fluids.h".
665 * eval.h (SCM_TOP_LEVEL_LOOKUP_CLOSURE): New macro which replaces
666 SCM_CDR (scm_top_level_lookup_closure_var) everywhere.
668 * root.h (scm_top_level_lookup_closure_var,
669 scm_system_transformer): Removed. (It's no sense in having the
670 *variable* be a "fluid".)
672 * root.c (mark_root): Removed marking of
673 s->top_level_lookup_closure_var and s->system_transformer.
675 * modules.c (scm_selected_module): the_module is now a fluid.
677 2000-06-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
679 * gc.h, tags.h: Be kind to compilers which must see hash signs in
680 column 0. (Thanks to Ian Grant.)
682 * numbers.h: Put #ifdef HAVE_LONG_LONGS around declarations using
683 the long_long type. (Thanks to Bernard Urban.)
685 2000-06-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
687 * gc.c, gc.h (scm_default_init_heap_size_1,
688 scm_default_min_yield_1, scm_default_init_heap_size_2,
689 scm_default_min_yield_2, scm_default_max_segment_size): New global
690 variables. Can be customized by the application before booting
691 Guile. (We might want to be able to control these parameters
692 dynamically through the "options interface" in the future, but
693 note that that is additional functionality. Here we're giving
694 default values which the environment variables can override.)
696 * list.c (scm_cons_star): Updated comment.
698 * smob.h: Changed comments for scm_make_smob_type and
699 scm_make_smob_type_mfpe, warning that the latter might be
700 deprecated in a future release.
702 2000-06-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
704 * list.[ch] (scm_cons_star/cons*): Renamed from
707 * list.[ch] (scm_list_star/list*): Provided as a deprecated alias
708 for scm_cons_star/cons*.
710 * gc.c (scm_protect_object): Updated comment.
712 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX): Removed.
714 * tags.h (SCM_UNPACK_CAR, SCM_NDOUBLE_CELLP): Removed.
716 2000-06-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
718 * init.c, init.h (scm_initialized_p): Renamed from `initialized'
721 * gdbint.c (gdb_print): Print warning instead of calling scm_write
722 if Guile isn't yet initialized.
724 * print.c (scm_current_pstate, scm_make_print_state): Simplified
725 tests, using the assumption that Guile has been initialized.
727 Sun Jun 18 14:45:21 2000 Greg J. Badros <gjb@cs.washington.edu>
729 * print.c (s_scm_current_pstate): Do not segfault when the
730 print_state_pool is unitialized in `current-pstate', and better
731 verify its state before altering it in scm_make_print_state().
733 2000-06-18 Michael Livshin <mlivshin@bigfoot.com>
735 * scmsigs.c (s_scm_sigaction): guard the SIGIOT case with an
736 #ifdef -- it's missing on at least one platform. (thanks to
739 2000-06-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
741 * list.c (list*): Added documentation from common-list.scm.
743 2000-06-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
745 * gc.c (scm_unprotect_object): The reference count is guaranteed
746 to be a positive number.
748 2000-06-15 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
750 * eval.c: Updated comment above scm_map.
752 2000-06-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
754 * gc.c (scm_protect_object): Avoid looking up the object handle
756 (scm_unprotect_object): Abort if scm_unprotect_object is called on
757 an unprotected object.
759 2000-06-14 Michael Livshin <mlivshin@bigfoot.com>
761 * gc.c (scm_unprotect_object): fix a nasty typo bug (thanks to
764 2000-06-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
766 * socket.c (scm_getsockopt): Changed type for `optlen' from int to
768 (scm_accept, scm_getsockname, scm_getpeername, scm_recvfrom):
769 Ditto for `tmp_size'.
770 (scm_addr_buffer_size): Changed type from int to size_t.
772 * random.c: #include <string.h>. (Needed by memcpy.)
774 * guile-snarf.awk.in: Replace the dot_doc_file arg with "-",
775 indicating stdin, instead of "" and don't reset ARGC. This is a
776 workaround for `nawk' in AIX 4.3 on RS6000 but, as far as I know,
777 it is correct, and perhaps even better.
779 2000-06-14 Gary Houston <ghouston@arglist.com>
781 * scmsigs.c (scm_init_scmsigs): if HAVE_SIGINTERRUPT is not
782 defined, add SA_RESTART to the sigaction flags correctly
783 (thanks to Dale P. Smith).
785 2000-06-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
787 * strings.c: #include <string.h>. (Thanks to Bill Schottstaedt.)
789 * net_db.c (scm_resolv_error): Only use macro NETDB_INTERNAL if
790 defined. It isn't on sgi irix 5.3. (Thanks to Bill Schottstaedt.)
792 * Makefile.am (.c.doc): Pipe output (the .x contents) to /dev/null.
794 2000-06-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
796 * fports.c (scm_setvbuf): Use `free' instead of `scm_must_free'
797 since read and write buffers are allocated by `malloc'.
799 * Makefile.am: Removed old test code.
801 * gh_test_c.c, gh_test_repl.c: Removed.
803 2000-06-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
805 * iselect.c (SCM_NLONGBITS): Add workaround for the Sun 4.2
808 * inet_aton.c (inet_aton): Cast init value for `cp'.
810 * ramap.c (s_scm_array_fill_x): Cast `ve' properly in case
813 * symbols.c (scm_intern_obarray_soft,
814 scm_sysintern0_no_module_lookup): Cast `name' to unsigned char ptr
815 in calls to scm_strhash.
817 * strports.c (st_resize_port): Substituted SCM_UCHARS for
819 (st_write): Cast argument to strncpy to char ptr.
820 (scm_mkstrport): Substituted SCM_ROUCHARS for SCM_ROCHARS.
821 (scm_strport_to_string): Cast argument to scm_makfromstr to char
824 * ports.c (scm_ungetc): Cast value to unsigned char ptr before
825 storing in putback_buf.
826 (scm_unread_string): Substituted SCM_ROCHARS for SCM_ROUCHARS.
828 * ioext.c (s_scm_read_line): Cast result of call to
829 scm_do_read_line to unsigned char ptr.
831 * gdbint.c (SEND_STRING): Cast argument to char pointer.
833 * fports.c (fport_flush): Declare `ptr' as unsigned char (was
836 * Makefile.am (DOT_DOC_FILES): List doc-files explicitly. (We
837 shouldn't use Make rules which aren't supported by most Make
839 (OMIT_DEPENDENCIES): Defined to "libguile.h ltdl.h". (We don't
840 want these dependencies recorded, since they would get bogus
841 relative paths; libguile.h is only used in gh.h and guile.c.)
842 (EXTRA_DOT_X_FILES, EXTRA_DOT_DOC_FILES): New variables.
843 (guile-procedures.txt): Depend on EXTRA_DOT_DOC_FILES.
844 (modinclude_HEADERS): Removed kw.h.
846 * guile-snarf.in: Change regexp "^SCM__I" --> "^ *SCM__I".
847 (The preprocessor might insert spaces before the identifier.)
849 * snarf.h (SCM_SNARF_HERE, SCM_SNARF_INIT, SCM_SNARF_DOCS):
850 Renamed from SCM_HERE, SCM_INIT, SCM_DOCS.
852 * smob.h (scm_smobfuns): Removed deprecated type.
854 * smob.c, smob.h (scm_newsmob): Removed deprecated function.
855 (Replaced by `scm_make_smob_type'.)
857 * keywords.c (scm_tc16_kw): Removed deprecated type.
858 (Replaced by scm_tc16_keyword.)
860 * kw.h: Removed deprecated header file.
862 * evalext.c (serial-map): Removed deprected alias for scm_map.
863 (Has been replaced by `map-in-order'.)
865 * ramap.c (serial-array-copy!, serial-array-map!): Removed
866 depracted aliases. (Replaced by `array-copy-in-order!' and
867 `array-map-in-order'.)
869 2000-06-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
871 * gc.h (SCM_VALIDATE_CELL): Rewritten.
872 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
873 SCM_SET_CELL_OBJECT): Use new version of SCM_VALIDATE_CELL.
874 (Thanks to Han-Wen Nienhuys.)
876 2000-06-10 Michael Livshin <mlivshin@bigfoot.com>
878 * guile-doc-snarf.in: don't pipe the CPP output right into sed --
879 write it to the temp file first and check the CPP return code.
880 (I introduced this bug earlier, and this probably caused people
881 with non-GNU C preprocessors to get empty *.x files and not to
882 have the build fail right away...).
884 * scmsigs.c (s_scm_sigaction): guard the SIGSYS case with an ifdef
885 -- at least my libc5-based Linux system doesn't define SIGSYS.
887 2000-06-08 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
889 * snarf.h, guile-snarf.awk.in, guile-snarf.in: Replaced snarf
890 markers with identifiers (SCM__I, SCM__D, SCM__S, SCM__E).
891 (Thanks to Bernard Urban.)
893 2000-06-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
895 * modules.c (scm_system_module_env_p): Fixed detection of system
898 2000-06-06 Marius Vollmer <mvo@zagadka.ping.de>
900 * scmsigs.c (scm_sigaction): Silently ignore setting handlers for
901 `program error signals' because they can't currently be handled by
904 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
906 * procs.h (SCM_SET_SUBRF): Added.
908 * procs.c (scm_make_subr_opt): Don't assign to SCM_SUBRF, use
909 SCM_SET_SUBRF instead. Thanks to Bernard Urban for the bug
912 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
914 * gc.h (SCM_CARLOC, SCM_CDRLOC): Don't take the address of a SCM
917 * sort.c (scm_sorted_p, scm_merge, scm_merge_list_x,
918 scm_merge_list_step): Don't take the address of SCM_CAR. Use
919 SCM_CARLOC instead. Thanks to Bernard Urban for the bug report.
921 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
923 * boolean.h (SCM_TRUE_P): Removed, as people might use it as a
924 replacement for !SCM_FALSEP.
926 * backtrace.c (display_error_body), boolean.h (SCM_BOOLP), gc.c
927 (scm_unhash_name), gh_data.c (gh_module_lookup), load.c
928 (scm_primitive_load), print.c (scm_simple_format), procs.c
929 (scm_procedure_documentation), procs.h (SCM_TOP_LEVEL), ramap.c
930 (scm_array_fill_int), scmsigs.c (scm_sigaction), stacks.c
931 (narrow_stack, scm_make_stack, scm_stack_id), symbols.c
932 (scm_string_to_obarray_symbol), throw.c (scm_catch,
933 scm_lazy_catch, scm_ithrow), unif.c (scm_make_uve, scm_array_p,
934 scm_array_set_x, scm_bit_set_star_x, scm_bit_count_star),
935 validate.h (SCM_VALIDATE_BOOL_COPY, SCM_VALIDATE_PROC): Replace
936 uses of SCM_TRUE_P (x) with SCM_EQ_P (x, SCM_BOOL_T).
938 2000-06-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
940 * eval.c (scm_badformalsp): New static function.
941 (SCM_CEVAL): Check arguments for procedure-with-setter closures.
942 (Thanks to Keisuke Nishida.)
944 The major reason for Guile's slow loading speed has been the fact
945 that a chain of Scheme level procedures has been evaluated for
946 every top-level symbol lookup during the first pass through the
949 The following is a kludge which I suggested four years ago, and
950 which I've repeatedly suggested since. Personally, I've never
951 been bothered by Guile's slow loading speed, so I thought I would
952 let someone else do it...
954 But since the new environments will be included first in
955 Guile-1.5, I thought it would make people happy to get the kludge
958 * modules.c: Added #include "libguile/vectors.h";
959 Added #include "libguile/hashtab.h";
960 Added #include "libguile/struct.h";
961 Added #include "libguile/variable.h";
962 Capture Scheme level `module-make-local-var!' to be used in the
963 standard eval closure.
964 (scm_standard_eval_closure): New primitive.
966 * modules.h (scm_standard_eval_closure): Declare.
968 * eval.c (scm_lookupcar): Test for !SCM_CONSP (SCM_CAR (env))
969 instead of SCM_TRUE (scm_procedurep (SCM_CAR (env))).
971 * symbols.c (scm_sym2vcell): Bypass dispatch in the evaluator for
972 standard eval closures.
974 * variable.c: Code layout fixes.
976 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
978 * Makefile.am: Added LIBS line to libpath which accidentally
979 disappeared in the change of 2000-06-01.
980 (Thanks to Dale P. Smith.)
982 2000-06-03 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
984 * scmsigs.c (scm_segfault): Removed. (Was probably added by
985 mistake since it is not mentioned in ChangeLog.)
987 * gc.h (SCM_VALIDATE_CELL): Cast result to (void) in order to
988 avoid compiler warnings in gcc. (Does this work for other
991 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
993 * gc.h (SCM_VALIDATE_CELL): Don't "use" the value returned by
995 (SCM_CARLOC, SCM_CDRLOC): Define directly instead of using
996 SCM_CELL_OBJECT_0 and SCM_CELL_OBJECT_1. It's not correct to take
997 the address of these expressions since they use SCM_VALIDATE_CELL.
998 (Thanks to Bernard Urban.)
1000 * dynl.c: Changed #include <ltdl.h> --> #include
1001 "libltdl/ltdl.h". (Thanks to Bill Schottstaedt.)
1003 2000-06-01 Craig Brozefsky <craig@red-bean.com>
1005 * Makefile.am: libguile_la_LDFLAGS gets -version-info args
1006 from GUILE-VERSION definition of LIBGUILE version. Added to
1007 libpath.h definitions for guileversion and libguileversion which
1008 both get their values from GUILE-VERSION definition.
1010 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
1012 * numbers.h (SCM_BIGP): Don't use SCM_SMOB_PREDICATE in header
1013 file: Code using numbers should not be required to include
1016 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
1018 * coop-threads.c.cygnus, coop-threads.h.cygnus, fsu-pthreads.h,
1019 mit-pthreads.c, mit-pthreads.h: Deleted.
1021 * Makefile.am (EXTRA_DIST), scmsigs.c, threads.[ch]: Drop
1022 references to deleted files and fsu/mit thread support in
1025 2000-05-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1027 * hooks.c (symbol_name, scm_create_hook): Restored the original
1028 behaviour of scm_create_hook. Changing it was bad as Carl
1029 R. Witty has pointed out.
1031 * gc.c (scm_init_gc): We can still rely on scm_create_hook to
1034 2000-05-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
1036 * gc.c (scm_init_gc): Protect scm_after_gc_hook, since this will
1037 soon not be done by scm_create_hook any longer.
1039 * hooks.c (make_hook, print_hook, scm_create_hook,
1040 scm_make_hook_with_name, scm_make_hook), hooks.h (SCM_HOOK_NAME,
1041 SCM_HOOK_PROCEDURES, SCM_SET_HOOK_PROCEDURES,
1042 scm_make_hook_with_name), init.c (scm_boot_guile_1): Hooks no
1043 longer have names. As an intermediate solution, the name
1044 predicate is emulated via object properties, but use of this
1045 feature is deprecated.
1047 * hooks.h (scm_free_hook): Removed, as it is never defined.
1049 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
1051 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_FIXABLE):
1052 Un-deprecated since otherwise user code can't determine whether a
1053 number fits into an inum any longer. The names should be changed
1056 * numbers.c (scm_big2inum): Eliminated use of SCM_UNEGFIXABLE.
1058 * tags.h (SCM_UNPACK_CAR): Deprecated.
1060 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
1062 * filesys.h (SCM_OPDIRP), fluids.h (SCM_FLUIDP, SCM_FLUID_NUM),
1063 fports.h (SCM_OPFPORTP, SCM_OPINFPORTP, SCM_OPOUTFPORTP), hooks.h
1064 (SCM_HOOK_ARITY), keywords.h (SCM_KEYWORDP, SCM_KEYWORDSYM),
1065 numbers.h (SCM_NUMP, SCM_BIGSIGN, SCM_BDIGITS, SCM_NUMDIGS):
1066 Replace SCM_UNPACK_CAR appropriately. Don't access cells via
1067 SCM_{SET}?C[AD]R unless they are known to be cons cells.
1069 * gc.c (scm_heap_seg_data_t, scm_mark_locations, scm_cellp,
1070 init_heap_seg): Remove unused struct member variable 'valid'.
1072 2000-05-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
1074 * fports.c (fport_write), ports.c (scm_markstream, scm_port_mode,
1075 scm_print_port_mode), ports.h (SCM_OPPORTP, SCM_OPINPORTP,
1076 SCM_OPOUTPORTP, SCM_INPUT_PORT_P, SCM_OUTPUT_PORT_P, SCM_OPENP),
1077 procs.h (SCM_CLOSCAR), unif.h (SCM_ARRAY_NDIM, SCM_ARRAY_CONTP),
1078 variable.h (SCM_VARIABLEP): Replace SCM_UNPACK_CAR
1081 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
1083 * gc.c (free_list_length), hash.c (scm_hasher), macros.c
1084 (scm_macro_type), objects.c (scm_class_of), options.c
1085 (scm_options), print.c (scm_iprin1), strports.c (st_seek), throw.c
1086 (SCM_LAZY_CATCH_P): Replace SCM_UNPACK_CAR appropriately.

1090 * eval.c (scm_macroexp, SCM_CEVAL, scm_force), tags.h: Replace
1091 SCM_UNPACK_CAR with SCM_CELL_TYPE or SCM_CELL_WORD_0.
1093 * eval.c (scm_force): Add documentation.
1095 * eval.c (scm_force, scm_cons_source): Don't access cells via
1096 SCM_{SET}?C[AD]R unless they are known to be cons cells.
1098 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
1100 * strings.h (SCM_NSTRINGP, SCM_NRWSTRINGP), tags.h
1101 (SCM_NDOUBLE_CELLP), vectors.h (SCM_NVECTORP): Deprecated.
1103 * gc.c (scm_igc), gc.h (SCM_PTR_MASK, SCM_PTR_LT): Removed #ifdef
1104 nosve #endif conditionally compiled code.
1106 2000-05-23 Michael Livshin <mlivshin@bigfoot.com>
1108 * gc.c (scm_heap_seg_data_t): fixed comment for the `span' member.
1110 2000-05-22 Michael Livshin <mlivshin@bigfoot.com>
1112 * guile-doc-snarf.in: put the preprocessed file through sed to
1113 trim all lines to 1024 chars. I hope it doesn't break anybody's
1114 sed. we'll see. (note: this is lossy trimming, i.e. the spill
1115 isn't wrapped around but actually chopped off. this seemed to me
1116 safe because the current snarfer doesn't understand multi-line
1117 cookies anyway. in the long term, it would be nice not to depend
1118 on AWK for anything.)
1120 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): reverted
1121 the previous change to this macros, after deciding to torture the
1124 2000-05-21 Michael Livshin <mlivshin@bigfoot.com>
1126 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): brought
1127 the yucky, ugly and nasty conditional compilation back. sorry,
1128 but it was either that or requiring GAWK to build Guile.
1129 (lots of places): removed the code that implemented the old GC
1132 * init.c (scm_boot_guile_1): removed the code conditioned on
1133 !GUILE_NEW_GC_SCHEME.
1135 * __scm.h: (GUILE_NEW_GC_SCHEME): removed.
1137 * gc.c (scm_protect_object, scm_unprotect_object): change the
1138 implementation to more efficient (at least in the time complexity
1139 sense). the calls should now also be thread-safe -- I suspect
1140 that people expect them to be. (thanks to Han-Wen Nienhuys)
1141 (lots of places): removed the code that implemented the old GC
1144 * hashtab.c (scm_hash_fn_create_handle_x): add missing
1145 SCM_REALLOW_INTS before return. I really wonder about the
1146 possible interactions between hashtables, threads & GC. it
1147 doesn't look healthy at all.
1149 2000-05-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
1151 * unif.c (scm_bit_count): Fixed the parameter checks. Thanks to
1154 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
1156 * __scm.h (SCM_DEBUG_CELL_ACCESSES), gc.h (SCM_): Added as a new
1157 debug option to verify all accesses to cells actually access
1158 objects on the heap.
1160 * gc.h (SCM_VALIDATE_CELL): Added. Only performs validation if
1161 SCM_DEBUG_CELL_ACCESSES is set to 1.
1163 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
1164 SCM_SET_CELL_OBJECT): Use SCM_VALIDATE_CELL to check every cell
1167 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
1169 * gh_data.c (gh_scm2chars, gh_scm2shorts, gh_scm2longs,
1170 gh_scm2floats, gh_scm2doubles): Change !SCM_NIMP to SCM_IMP.
1172 * gc.c (scm_cellp): Fixed and simplified.
1174 * throw.c (JBJMPBUF, SETJBJMPBUF, SCM_JBDFRAME, SCM_SETJBDFRAME,
1175 make_jmpbuf, scm_init_throw): Now using double cells to represent
1176 jump buffers when using debug extensions.
1180 2000-05-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
1182 * gh.h gh_data.c gh_funcs.c (gh_new_procedure*, gh_chars2byvect,
1183 gh_shorts2svect, gh_longs2ivect, gh_ulongs2uvect, gh_floats2fvect,
1184 gh_doubles2dvect, gh_doubles2scm, gh_define, gh_lookup,
1185 gh_module_lookup): Accept const pointers as parameters.
1187 * gh.h gh_data.c (gh_int2scmb): Deprecated.
1189 2000-05-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
1191 * __scm.h (SCM_DEBUG_REST_ARGUMENT): Renamed from
1192 SCM_DEBUG_REST_ARGUMENTS in order to clarify that we don't test
1193 the actual arguments in the list, but rather the rest argument as
1194 a list of arguments.
1196 * validate.h (SCM_VALIDATE_REST_ARGUMENT): Added.
1198 * async.c (scm_noop), eval.c (scm_map, scm_for_each), list.c
1199 (scm_list_star, scm_append, scm_append_x), ports.c
1200 (scm_close_all_ports_except), ramap.c (scm_array_map_x,
1201 scm_array_for_each), regex-posix.c (scm_make_regexp), stacks.c
1202 (scm_make_stack), strings.c (scm_string_append), struct.c
1203 (scm_make_struct, scm_make_vtable_vtable): Validate rest arguments.
1205 * dynl.c (DYNL_GLOBAL, sysdep_dynl_link, kw_global, sym_global,
1206 scm_dynamic_link, scm_init_dynamic_linking), dynl.h
1207 (scm_dynamic_link): Removed possibility to pass flags to
1208 scm_dynamic_link, as it had no effect anyway.
1210 * filesys.c (scm_fcntl): Made single optional rest argument into
1211 a standard optional argument.
1213 * hooks.c (scm_run_hook): A list of rest arguments is never
1216 * list.c (scm_append, scm_append_x), stacks.c (scm_make_stack),
1217 strings.c (scm_string_append): Don't perform half-hearted checks
1218 to see whether the rest argument forms a proper list any more, use
1219 SCM_VALIDATE_REST_ARGUMENTS instead.
1221 * ports.c (scm_close_all_ports_except): Accept empty list of rest
1224 * posix.c (scm_convert_exec_args), print.c (scm_simple_format):
1225 Simplify verification of rest argument.
1227 * stacks.c (scm_make_stack), stacks.h (scm_make_stack), throw.c
1228 (ss_handler, handler_message): Make first mandatory rest argument
1229 of scm_make_stack into a standard mandatory argument.
1231 * unif.c (scm_transpose_array, scm_enclose_array,
1232 scm_array_in_bounds_p), unif.h (scm_transpose_array,
1233 scm_enclose_array, scm_array_in_bounds_p): Make first mandatory
1234 rest argument into a standard mandatory argument.
1236 2000-05-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
1238 * __scm.h: Added SCM_DEBUG as default debug option. (Thanks to
1239 Keisuke Nishida for the suggestion.) Added debug option
1240 SCM_DEBUG_REST_ARGUMENTS.
1242 * eval.c (scm_map, scm_for_each): Make sure all lists have the
1243 same length. Also, removed redundant parameter checks.
1245 2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
1247 * Makefile.am: Let 'make clean' remove *.x and *.doc files.
1249 * __scm.h: Improved explanation of giving options to make.
1251 * __scm.h (SCM_DEBUG_TYPING_STRICTNESS), tags.h
1252 (SCM_STRICT_TYPING, SCM_DEBUG_TYPING_STRICTNESS): Renamed
1253 SCM_STRICT_TYPING to SCM_DEBUG_TYPING_STRICTNESS and moved the
1254 corresponding declaration and comment to __scm.h.
1256 * _scm.h (errno), gc.h (SCM_CELLPTR, SCM_PTR_LT), numbers.c
1257 (scm_remainder, scm_modulo), numbers.h (SCM_SRS, SCM_MAKINUM,
1258 SCM_INUM): Removed conditionally compiled code for Turbo C.
1260 * gdbint.c (gdb_maybe_valid_type_p): Eliminated call to scm_tag.
1261 That check can be assumed to be redundant except for very rare
1262 conditions that actually indicate broken heap data.
1264 2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
1266 * numbers.c (scm_logcount, scm_integer_length): Reordered
1269 2000-05-15 Gary Houston <ghouston@arglist.com>
1271 * stime.c (scm_strftime): don't reset TZ if zone is an empty
1272 string. append a "0" to the zone for TZ.
1274 2000-05-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
1276 * numbers.c (scm_logbit_p, scm_bit_extract): Reordered dispatch
1279 (scm_bit_extract): Fixed handling of bignums.
1281 2000-05-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
1283 * async.c (scm_sys_gc_async_thunk), chars.h (SCM_ICHRP, SCM_ICHR,
1284 SCM_MAKICHR), continuations.h (SCM_SETJMPBUF), error.c
1285 (scm_sysmissing), error.h (scm_sysmissing), evalext.c
1286 ('serial-map), ioext.c (scm_fseek), ioext.h (scm_fseek),
1287 keywords.c (scm_tc16_kw, scm_init_keywords), ports.h (SCM_CRDY,
1288 SCM_INPORTP, SCM_OUTPORTP), ramap.c ('serial-array-copy!,
1289 'serial-array-map!), smob.c (scm_newsmob), smob.h (scm_smobfuns,
1290 scm_newsmob), tag.c (scm_tag), tag.h (scm_tag), tags.h
1291 (scm_tc16_flo, scm_tc_flo, scm_tc_dblr, scm_tc_dblc): Wrapped
1292 deprecated code between #if (SCM_DEBUG_DEPRECATED == 0) #endif.
1294 * fports.c (scm_fport_buffer_add), ports.c (scm_input_port_p,
1295 scm_output_port_p), print.c (scm_get_print_state), validate.h
1296 (SCM_VALIDATE_CHAR): Replace use of deprecated macros
1297 SCM_INPORTP, SCM_OUTPORTP, SCM_ICHRP by SCM_INPUT_PORT_P,
1298 SCM_OUTPUT_PORT_P, SCM_CHARP, respectively.
1300 2000-05-14 Gary Houston <ghouston@arglist.com>
1302 * stime.c (scm_strftime): if HAVE_TM_ZONE is not defined, hack the
1303 TZ environment variable so that the %Z format returns the zone
1304 from the input vector instead of the system default.
1306 from Keisuke Nishida:
1307 * fports.c (scm_setvbuf): minor docstring fix.
1308 * ports.h (scm_generic_fgets): obsolete prototype deleted.
1310 2000-05-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
1312 * __scm.h: Added new section for debugging options.
1314 (SCM_DEBUG_DEPRECATED): If 1, no deprecated code is included to
1315 help developers to get rid of references to deprecated code.
1317 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_UNEGFIXABLE,
1318 SCM_FIXABLE, SCM_FLOBUFLEN): These macros are no longer provided
1319 as part of the interface and are marked as deprecated in the
1322 * numbers.c (scm_make_real, scm_make_complex): Inlined the
1323 corresponding macros SCM_NEWREAL and SCM_NEWCOMPLEX,
1326 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX, SCM_INEXP, SCM_CPLXP,
1327 SCM_REAL, SCM_IMAG, SCM_REALPART, scm_makdbl, SCM_SINGP,
1328 SCM_NO_BIGDIG, SCM_NUM2DBL, scm_dblproc): Deprecated.
1330 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1332 * gc.h (scm_cell, SCM_CELL_WORD, SCM_CELL_OBJECT,
1333 SCM_SET_CELL_WORD, SCM_SET_CELL_OBJECT): Scheme cells now consist
1334 of two scm_bits_t values instead of two SCM values, because it is
1335 legal for cell entries to hold values that are not scheme objects.
1337 (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR):
1338 Use SCM_SETC[AD]R to modify contents of pairs.
1340 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1342 * numbers.c (IS_INF, isfinite): Added FIXME comment.
1344 (scm_abs, scm_magnitude): Make these two independent of each
1345 other. scm_abs now reports an error if given a complex argument.
1347 (scm_istr2flo, scm_integer_p). Use SCM_REAL_VALUE instead of
1348 SCM_REALPART if the object is known to be real.
1350 (scm_init_numbers): No need to use SCM_NEWREAL macro for speed
1353 * numbers.h (SCM_SINGP): Set to 0 instead of SCM_BOOL_F.
1355 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1357 * eq.c (scm_eqv_p): Separate handling of real and complex
1358 values. Remove #ifdef SCM_BIGDIG #endif test.
1360 * eval.c (SCM_CEVAL, SCM_APPLY), gh_data.c (gh_scm2floats,
1361 gh_scm2doubles), hash.c (scm_hasher), ramap.c (scm_array_fill_int,
1362 ramap_rp, scm_array_map_x), random.c (vector_scale,
1363 vector_sum_squares), unif.c (scm_make_uve, scm_array_p,
1364 scm_array_set_x): Use SCM_REAL_VALUE instead of SCM_REALPART if
1365 the object is known to be real. Use SCM_COMPLEXP instead of
1366 deprecated SCM_CPLXP. Use SCM_INEXACTP instead of deprecated
1369 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1371 * numbers.c: No need to include unif.h.
1373 (IS_INF): Returned to old test for now: x == x + 1 will not work
1374 for large numbers due to rounding errors.
1375 Thanks to Kalle Olavi Niemitalo.
1377 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
1379 * numbers.c (scm_divbigdig): Removed outdated comment.
1381 (scm_number_to_string, scm_string_to_number, scm_number_p,
1382 scm_real_p, scm_integer_p, scm_inexact_p, scm_gr_p, scm_leq_p,
1383 scm_geq_p, scm_make_rectangular, scm_make_polar,
1384 scm_inexact_to_exact): Added comments.
1386 (add1, scm_init_numbers): Removed add1.
1388 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
1390 * numbers.c (IS_INF): The new test is x == x + 1. The old test
1391 x == x/2 did not work for zero values. Thanks to Han-Wen Nienhuys
1394 (scm_number_to_string, scm_sum, scm_difference, scm_two_doubles,
1395 scm_num2long, scm_num2long_long, scm_num2ulong): Reordered
1398 2000-05-09 Marius Vollmer <mvo@zagadka.ping.de>
1400 * scmsigs.c (take_signal): Execute SCM_ASYNC_TICK for SIGSEGV,
1401 SIGILL and SIGBUS signals. These signals are not continuable and
1402 must be handled for real right away.
1404 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1406 * numbers.c (scm_zero_p, scm_positive_p, scm_negative_p,
1407 scm_real_part, scm_imag_part, scm_magnitude,
1408 scm_inexact_to_exact): Reordered dispatch sequence.
1410 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1412 * feature.c: No need to include "libguile/smob.h"
1414 (scm_loc_features, features, scm_add_feature, scm_init_feature):
1415 Removed variable 'scm_loc_features' as a pointer to the SCM value
1416 holding the features list. Using variable 'features' instead,
1417 which holds the interned pair. Thus, SCM_SETCDR can be used
1418 instead of pointer trickery.
1420 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1422 * alist.c (scm_acons): Use SCM{_SET}?_CELL_OBJECT as long as a
1423 cell is not known to be a valid pair.
1425 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1427 * eval.c (ASRTSYNTAX, scm_m_body, scm_m_letrec1): Removed
1428 ASRTSYNTAX. Using SCM_ASSYNT instead.
1430 (scm_m_body): Don't create a redundant cons cell.
1432 (scm_m_do): Removed redundant test 'bodycheck'.
1434 (bodycheck): Removed.
1436 * stacks.c (stack_depth, read_frame, read_frames): Removed
1437 redundant calculation of size, minimized some variable scopes.
1439 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1441 * pairs.c (scm_cons, scm_cons2): Use SCM{_SET}?_CELL_OBJECT as
1442 long as a cell is not known to be a valid pair.
1444 (scm_pair_p): Eliminated redundant SCM_IMP test.
1446 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1448 * eval.c (scm_m_body, scm_macroexp, unmemocopy, scm_eval_args,
1449 scm_deval_args): Eliminated redundant SCM_IMP tests.
1451 * hashtab.c (scm_ihashx, scm_sloppy_assx, scm_delx_x), weaks.c
1452 (scm_make_weak_key_hash_table, scm_make_weak_value_hash_table,
1453 scm_make_doubly_weak_hash_table): Fixed critical sections.
1454 Thanks to Keisuke Nishida.
1456 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1458 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest):
1459 Fixed some goto-related initialization bugs (introduced by me).
1461 2000-05-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
1463 * numbers.h (SCM_INUM0): Uses SCM_MAKINUM instead of SCM_PACK.
1465 * dynl.c (dynl_obj, DYNL_OBJ, get_dynl_obj): Removed.
1467 (DYNL_FILENAME, DYNL_HANDLE): Use SCM_CELL... macros instead of
1470 (SET_DYNL_HANDLE): Added.
1472 (scm_dynamic_object_p): Simplified.
1474 (scm_dynamic_unlink, scm_dynamic_func): Changed comment. Deliver
1475 better error message when accessing unlinked dynamic objects.
1476 Eliminated call to get_dynl_obj.
1478 2000-05-03 Marius Vollmer <mvo@zagadka.ping.de>
1480 * scmsigs.c (orig_handlers) [!HAVE_SIGACTION]: Fix declaration to
1481 be an array of function pointers instead of being a pointer to an
1482 array returning function. Thanks to Kalle Olavi Niemitalo!
1484 2000-05-03 Dirk Herrmann <D.Herrmann@tu-bs.de>
1486 * numbers.c (scm_divbigbig, scm_divbigint), numbers.h
1487 (scm_divbigbig, scm_divbigint): Don't return zero any more to
1488 indicate that a division has a remainder, return SCM_UNDEFINED
1489 instead. It is improbable that anyone actually used these
1490 functions outside of numbers.c. For this reason and due to the
1491 change in behaviour the functions are static now. Thus, if
1492 surprisingly there are users of these functions they will at least
1495 * numbers.c: Removed #ifdef SCM_BIGDIG #endif in those functions,
1496 that already have a clean dispatch order. Note: SCM_BIGDIG is
1499 * numbers.c (scm_inexact_p): Simplified.
1501 * numbers.c (scm_num_eq_p, scm_less_p, scm_max, scm_min,
1502 scm_product, scm_num2dbl, scm_angle): Reordered dispatch
1503 sequence, thereby fixing some comparisons of SCM values with
1506 * numbers.c (scm_divide): Division by zero of inums leads to an
1507 error now. (Formerly, an infinite number was returned.)
1509 Respect the fact, that scm_divbigbig does now return SCM_UNDEFINED
1510 if a division has a remainder.
1512 2000-05-02 Gary Houston <ghouston@arglist.com>
1514 * Makefile.am (INCLUDES): add ${INCLTDL} (thanks to Tim Mooney).
1516 2000-05-02 Dirk Herrmann <D.Herrmann@tu-bs.de>
1518 * numbers.c (scm_logtest, scm_division): Reordered dispatch
1519 sequence, thereby fixing some comparisons of SCM values with
1522 * numbers.h (scm_makdbl): Mark as deprecated at the point of
1525 * eval.c (SCM_CEVAL, SCM_APPLY), gh_data.c (gh_double2scm,
1526 gh_doubles2scm), numbers.c (scm_istr2flo, scm_max, scm_min,
1527 scm_sum, scm_difference, scm_product, scm_divide, scm_sys_expt,
1528 scm_sys_atan2, scm_make_rectangular, scm_make_polar,
1529 scm_real_part, scm_imag_part, scm_magnitude, scm_angle,
1530 scm_long2num, scm_long_long2num, scm_ulong2num), ramap.c
1531 (ramap_rp, scm_array_map_x), random.c (scm_random,
1532 scm_random_uniform, scm_random_normal_vector_x, scm_random_exp),
1533 struct.c (scm_struct_ref), unif.c (scm_array_to_list): Replace
1534 call to scm_makdbl with a call to scm_make_real or
1535 scm_make_complex, depending on whether the imaginary part is known
1538 2000-05-01 Gary Houston <ghouston@arglist.com>
1540 * scmsigs.c: fix the definition of orig_handlers for the case
1541 that HAVE_SIGACTION is not defined (thanks to
1542 Kalle Olavi Niemitalo).
1544 * Makefile.am: remove include_HEADERS (was libguile.h)
1545 libguile.h: moved to top level directory.
1547 2000-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1549 * numbers.c (SCM_SWAP): Moved to the top of the file to allow for
1552 * numbers.c (scm_modulo, scm_gcd, scm_lcm, scm_logand, scm_logior,
1553 scm_logxor): Reordered dispatch sequence, thereby fixing some
1554 comparisons of SCM values with integer constants.
1556 * number.c (scm_logtest): Removed some redundant SCM_{N}?IMP
1559 2000-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1561 * numbers.c (scm_quotient, scm_remainder): Removed code that was
1562 conditionally compiled based on BADIVSGNS. BADIVSGNS does not
1563 occur anywhere else throughout guile.
1565 * numbers.c (scm_quotient): Fixed parameter number in error
1568 * numbers.c (scm_remainder): Reordered dispatch sequence.
1570 2000-04-25 Gary Houston <ghouston@arglist.com>
1572 * posix.c (scm_execlp): docstring fix (thanks to Martin
1575 2000-04-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
1577 * eval.c (undef_object): Made into a local static variable
1578 (suggested by Jost Boekemeier).
1580 2000-04-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
1582 * pairs.c (cxrs, scm_init_pairs): Simplify initialization of
1585 * procs.c (scm_init_iprocs), procs.h (scm_subr, scm_iproc,
1586 scm_dsubr, scm_init_iprocs): Removed.

1682 * gc.c (which_seg): Use SCM2PTR to convert a non immediate SCM

1967 * async.h: kill the scm_async_t struct. having a heap cell

2039 separate loop after processing all the currently known live
2040 guardians, so as to not introduce order dependencies (thanks to
2041 Gary Houston). note that the order problems are still there if
2042 some guardians are themselves zombies, but that's a sick case that
2043 I'm not going to worry about.
2044 also, make another outer loop to process zombified
2045 guardians (which are uncovered while marking zombies).

2084 scm_hash_fold), load.c (load, scm_primitive_load): Passing SCM
2085 values via void * requires unpacking / packing.
2087 * fports.c (scm_fport_buffer_add, scm_setvbuf), procs.h
2088 (SCM_SUBRNUM, SCM_SET_SUBRNUM), srcprop.h (SRCPROPBRK, SRCBRKP):

2126 and static variables at their point of declaration, but rather in
2129 * tags.h (SCM_PACK): Automatically cast to scm_bits_t.
2131 2000-04-02 Gary Houston <ghouston@arglist.com>
2133 * guardians.c (TCONC_IN, scm_make_guardian): set the CDR of the
2134 empty tconc pair to SCM_EOL instead of SCM_BOOL_F, avoiding the
2135 use of an improper list (which breaks g_print. g_print isn't
2137 guardians.c: Added more comments and modified the make-guardian
2138 docstring. Reordered a few procedures.
2140 2000-04-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
2142 * eval.c (scm_lookupcar1, scm_lookupcar, scm_m_case, scm_m_cond,
2143 scm_m_lambda, iqq, scm_m_define, scm_m_expand_body, unmemocopy,
2144 SCM_CEVAL), procs.h (SCM_TOP_LEVEL): Don't use C operators to
2147 (scm_makprom): Smob data is of type scm_bits_t.

2157 access raw cell data with SCM_{SET_}?CELL_WORD_1.
2159 * debug.c (scm_make_debugobj): Don't use SCM_SETCAR to set types.
2161 * debug.c (scm_make_memoized), dynl.c (scm_dynamic_link): Smob

2176 strports.c (st_resize_port, scm_mkstrport), vports (sf_flush,
2177 sf_write, sf_fill_input, sf_close, scm_make_soft_port): Since
2178 streams are now of type scm_bits_t, SCM streams have to be
2181 * ports.h (SCM_SETPTAB_ENTRY, SCM_SETSTREAM): Cast input to
2184 2000-03-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2186 * coop-defs.h (struct coop_t): Added `sto'-field again because of
2187 binary compatibility---let's remove it next time we alter some
2190 * coop.c (coop_quitting_p, coop_cond_create, coop_mutex_create,
2191 coop_mother, coop_child): New variables.
2192 (mother): New function.
2193 (coop_create): New thread spawning mechanism which uses a "mother
2194 thread". The "dummy" pthreads aren't healthy enough to give birth
2195 to new threads since Linux threads thinks they are asleep.
2197 * coop-defs.h (struct coop_t): Removed dummy_mutex.
2199 * coop-defs.h, coop-threads.c (struct coop_t): Eliminate
2200 `sto'-field when GUILE_PTHREAD_COMPAT is enabled.
2202 2000-03-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
2204 * arbiters.c (scm_make_arbiter), async.c (scm_async), dynwind.c
2205 (scm_internal_dynamic_wind): Smob data is always of type
2208 * arbiters.c (SCM_ARB_LOCKED, SCM_LOCK_ARB, SCM_UNLOCK_ARB):
2209 Access the locking information in cell entry 0 with
2210 SCM_{SET_}?CELL_WORD_0 instead of SCM_*CAR.
2212 * async.c (scm_run_asyncs): Use SCM_NULLP to test for the empty
2215 * dynwind.c (scm_dowinds): Use SCM_EQ_P to compare SCM values.
2217 * ports.h (SCM_PTAB_ENTRY, SCM_SETPTAB_ENTRY): Access the ptab

2224 scm_sloppy_memq, scm_delq_x, scm_delq1_x), tags.h (SCM_UNBNDP):
2225 Don't use C operators == and != to compare SCM values, use
2228 * boolean.c (scm_boolean_p): Use SCM_BOOLP to determine whether a
2229 SCM value is equal to #t or #f.
2231 * eq.c (scm_eqv_p, scm_equal_p): Don't use SCM_CAR to access the
2232 cell type entry of non immediate objects of unknown type. Use
2233 SCM_CELL_TYPE instead.
2235 * gh_data.c (gh_scm2bool, gh_module_lookup), list.c
2236 (scm_sloppy_memv, scm_sloppy_member, scm_delv_x, scm_delete_x,

2238 SCM_FALSEP and SCM_TRUE_P to compare SCM values against #f and
2241 * list.c (scm_listify): Use SCM_UNBNDP to test for an unbound
2244 2000-03-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2246 * coop-threads.c (scm_call_with_new_thread, scm_spawn_thread,
2247 scm_make_mutex, scm_make_condition_variable): Cast data to
2248 scm_bits_t in SCM_SET_CELL_WORD and SCM_NEWSMOB macros.
2250 * coop.c (coop_create): Set `specific' field, not `data' to NULL.
2252 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
2254 * smob.h (SCM_NEWSMOB, SCM_NEWSMOB2, SCM_NEWSMOB3, SCM_SMOB_DATA,
2255 SCM_SET_SMOB_DATA, SCM_TC2SMOBNUM, SCM_SMOBNUM): To access smob
2256 data, use SCM_{SET_}?CELL_TYPE or SCM_{SET_}?WORD_[1-3].
2258 Note that this implies that smob data has always to be passed as
2259 values of type scm_bits_t.
2261 2000-03-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2263 * threads.c (scm_init_threads): Pass 0 size to scm_make_smob_type
2264 for scm_tc16_thread. As the current COOP threads are written, GC
2265 is not supposed to manage storage for threads.
2267 * error.c (scm_error): Don't try to throw an error if
2268 scm_gc_heap_lock is true.
2270 * coop.c (coop_finish): New function. Called at exit.
2271 (coop_aborthelp): Free thread structures when threads die.
2272 Finished LinuxThreads compatibility support => COOP threads now
2273 mesh with LinuxThreads.
2275 * coop-threads.c (scm_call_with_new_thread, scm_spawn_thread):
2276 Changed SETCDR --> SET_CELL_WORD_1.
2278 * coop-threads.c (scheme_launch_thread): Set word 1 of handle to 0
2281 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
2283 * boolean.h (SCM_TRUE_P): New macro.
2285 * boolean.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOLP), pairs.h
2286 (SCM_NULLP, SCM_NNULLP): Use SCM_EQ_P to compare SCM values.
2288 2000-03-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
2290 * continuations.h (SCM_CONTREGS, SCM_SET_CONTREGS): New macros to
2291 access continuation data.
2293 (SCM_SETJMPBUF): Deprecated. Use SCM_SET_CONTREGS instead.
2295 (SCM_JMPBUF, SCM_DYNENV, SCM_THROW_VALUE, SCM_BASE, SCM_SEQ,
2296 SCM_DFRAME): Use SCM_CONTREGS instead of SCM_CHARS to access
2299 * continuations.c (scm_make_cont), init.c (start_stack),
2300 root.c (scm_internal_cwdr): Use SCM_SET_CONTREGS instead of
2303 2000-03-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
2305 * symbols.h (SCM_LENGTH, SCM_SETLENGTH): Access the length field
2306 of strings and symbols by using SCM_{SET_}?CELL_WORD_0.
2308 (SCM_CHARS, SCM_UCHARS, SCM_SETCHARS): Use SCM_{SET_}?CELL_WORD_1
2309 to access the char * field of strings and symbols.
2311 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
2313 * gc.h (SCM_NEWCELL, SCM_NEWCELL2): Use SCM_SET_CELL_TYPE to set
2314 the type entry of a new cell. Added a comment about things to
2315 remember when updating the list of free cells.
2317 (SCM_FREEP, SCM_MARKEDP): Use SCM_CELL_TYPE to access the type
2320 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
2322 * pairs.h (SCM_CAR, SCM_CDR, SCM_SETCAR, SCM_SETCDR): Use
2323 SCM_CELL_OBJECT and SCM_SET_CELL_OBJECT. This change implies that
2324 with strict type checking enabled these macros will only work if
2325 given valid SCM parameters.
2327 (SCM_GCCDR): Moved to tags.h.
2329 * tags.h (SCM_GCCDR): Moved here from pairs.h.
2331 2000-03-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
2333 * tags.h (SCM2PTR, PTR2SCM): Moved to gc.h.
2335 * pairs.h (scm_cell, SCM_CELLPTR, SCM_CELL_WORD*, SCM_CELL_OBJECT*,
2336 SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*, SCM_CELL_TYPE,
2337 SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK, SCM_PTR_GT,
2338 SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC, SCM_NEWCELL,
2339 SCM_NEWCELL2): Moved to gc.h.
2341 (SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR, SCM_SETAND_CDR,
2342 SCM_SETOR_CAR, SCM_SETOR_CDR): Moved to gc.h. These names should
2343 be changed, though, since the macros are not only pair related.
2347 * gc.h (SCM2PTR, PTR2SCM, scm_cell, SCM_CELLPTR, SCM_CELL_WORD*,
2348 SCM_CELL_OBJECT*, SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*,
2349 SCM_CELL_TYPE, SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK,
2350 SCM_PTR_GT, SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC,
2351 SCM_NEWCELL, SCM_NEWCELL2, SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR,
2352 SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR): Moved here from
2355 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2357 * tags.h (SCM_STRICT_TYPING): New macro that, if defined,
2358 activates strict compile time type checking for variables of
2360 (SCM, SCM_PACK, SCM_UNPACK): Define according to whether
2361 SCM_STRICT_TYPING or SCM_VOIDP_TEST are defined.
2362 (SCM_EQ_P): Defined as a macro equivalent for eq?.
2364 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2366 * tags.h (SCM_POINTERS_MUNGED): Removed.
2368 * gc.c (scm_gc_sweep, init_heap_seg): Removed use of
2369 SCM_POINTERS_MUNGED, thus fixing some illegal casts to SCM.
2371 2000-03-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
2373 * pairs.h (SCM_CELL_OBJECT, SCM_CELL_OBJECT_[0-3],
2374 SCM_SET_CELL_OBJECT, SCM_SET_CELL_OBJECT_[0-3], SCM_CELL_TYPE,
2375 SCM_SET_CELL_TYPE): Added a set of low level macros for accessing
2377 (SCM_CELL_WORD_[0-3]): Renamed from the SCM_CELL_WORD[0-3].
2379 * procs.h, procs.c: Instead of SCM_{SET_}?CELL_WORD[12], use the
2380 newly introduced SCM_{SET_}?CELL_OBJECT_[12] macros.
2382 2000-03-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2384 * tags.h: Disabled definition of SCM_VOIDP_TEST.
2386 Defining SCM as void * introduces problems which haven't been
2387 handled yet. Developers who work with these issues can enable it
2388 in their working copies.
2390 Disabling this definition exposes a set of newly introduced and
2391 older misuses of types which causes warning messages during
2392 compilation. We'll fix this successively.
2394 * gc.c (scm_mark_locations): Changed * (SCM **) X --> * (SCM *) X
2395 in order to obtain a value of type SCM.
2396 (scm_cellp): Updated with new changes to scm_mark_locations.
2398 * continuations.h (SCM_SETJMPBUF): Cast second arg into SCM.
2400 * continuations.c (scm_make_cont): Removed cast of size_t into
2403 * symbols.h (SCM_SETCHARS): Cast second arg into SCM.
2405 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
2407 * numbers.h (SCM_SETNUMDIGS): Use SCM_BIGSIZEFIELD macro for
2408 shifting, not constant. Thanks to Dale P. Smith.
2410 * numbers.c (scm_sum, scm_difference): Don't test a SCM value
2411 for being less than zero. Decode it to a C value first. Again,
2414 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
2416 * numbers.h, ramap.c, struct.h, vectors.h: Don't use SCM2PTR for
2417 non scheme values. If raw data is stored in SCM variables, it has
2418 to be accessed using SCM_UNPACK until a better solution is found.
2420 2000-03-22 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2422 * tags.h (SCM_ECONSP, SCM_NECONSP): More corrections of
2423 pointer-arithmetic induced by the SCM_PACK/UNPACK change.
2425 * print.c (scm_iprin1): SCM_PACK/UNPACK corrections.
2427 * gc.c (scm_gc_sweep): SCM_PACK/UNPACK corrections.
2429 * eval.c (SCM_CEVAL, scm_unmemocar): SCM_PACK/UNPACK corrections.
2431 * dynwind.c (scm_swap_bindings): SCM_PACK/UNPACK corrections.
2433 * async.c, __scm.h: Removed lots of the old async click logic. It
2434 is possible to reinsert it by defining GUILE_OLD_ASYNC_CLICK in
2435 __scm.h. Let's try this out and dump the old code after the
2436 threads reorganization.
2437 (set-tick-rate, set-switch-rate): Conditionally removed.
2439 2000-03-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2441 * gc.c (scm_gc_mark): Bugfix 1: The recent SCM_PACK/UNPACK change
2442 made SCM values into pointers. This turned an arithmetic
2443 computation of the address of the vcell into a pointer-arithmetic
2444 one, thereby screwing up marking of structs.
2445 Bugfix 2: Removed incompletely introduced loop variable `j' used
2446 when protecting the tail array of a struct.
2448 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2450 * struct.h (SCM_STRUCT_DATA): Don't cast SCM values to pointers.
2452 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2454 * symbols.h, symbols.c (scm_strhash): Declare the string
2455 parameter as constant, since it is not modified.
2457 * symbols.c (scm_intern_obarray_soft,
2458 scm_sysintern0_no_module_lookup): Can now pass constant strings
2459 to scm_strhash without need for casting.
2461 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2463 * vectors.h (SCM_VELTS, SCM_VELTS_AS_STACKITEMS): Don't cast SCM
2464 values to pointers. Use SCM2PTR instead.
2466 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2468 * async.c (scm_set_tick_rate, scm_set_switch_rate): Don't unpack
2469 results of SCM_INUM.
2471 2000-03-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2473 * init.c (scm_boot_guile_1): Renamed GUILE_GC_TRIGGER_1 -->
2474 GUILE_MIN_YIELD_1, GUILE_GC_TRIGGER_2 --> GUILE_MIN_YIELD_2.
2475 GUILE_MIN_YIELD_X now take *positive* fractions of heap size.
2477 * gc.c, gc.h (SCM_MIN_YIELD_1, SCM_MIN_YIELD_2,
2478 min_yield_fraction, min_yield, adjust_min_yield): Renamed from
2479 SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2, gc_trigger_fraction,
2480 gc_trigger, adjust_gc_trigger.
2482 * gc.c (alloc_some_heap): Further improvement of minimal heap size
2484 (SCM_MAX): New macro.
2485 (scm_freelist_t): New field: collected_1. Previous amount of
2487 (gc_sweep_freelist_finish): Trigger based on two last values of
2488 freelist->collected to avoid unnecessary allocation due to
2490 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2):
2491 Adjusted to 45000 cells, 40% and 40%. Gives quick startup
2492 without extra heap allocation.
2494 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2496 * numbers.h (SCM_MAKINUM): The parameter to SCM_MAKINUM should
2497 already be a C value. No need to unpack it.
2499 * numbers.c (scm_long_long2num): Cast the parameter to scm_bits_t
2500 if we know it fits into an inum.
2502 * ramap.c (ramap_rp): An scm_tc7_[ui]vect object does point to a
2503 field of long values. In contrast, SCM_VELTS accesses a field of
2506 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2508 * gc.c (scm_gc_stats): Inserted explanation of local_scm_mtrigger
2510 (scm_gc_yield_1): New variable: Holds previous yield. Used to
2511 make better judgements.
2512 (gc_sweep_freelist_finish): Inserted explanation of use of
2515 * print.h, stacks.h, options.c, options.h: Changed C++
2518 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2520 * tags.h (SCM2PTR, PTR2SCM): Use SCM_PACK / SCM_UNPACK correctly.
2522 * numbers.h (SCM_INUMP, SCM_MAKINUM, SCM_INUM0, SCM_COMPLEX_REAL,
2523 SCM_COMPLEX_IMAG, SCM_NUMP, SCM_BDIGITS): Use SCM_PACK /
2524 SCM_UNPACK / SCM2PTR correctly.
2526 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2528 * gc.c (adjust_gc_trigger): Improved documentation.
2529 (alloc_some_heap): Since gc_trigger is used against
2530 freelist->collected, this is the value which should be used to
2531 predict minimum growth.
2533 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2535 * eval.h: Fix mixup of packed/unpacked SCM values. (Thanks
2536 Thien-Thi Nguyen for the patch.)
2538 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2540 * numbers.c (scm_ash): Fixed typing problems with the second
2541 parameter and added some documentation. (Thanks Thien-Thi Nguyen
2542 for indicating the problem.)
2544 2000-03-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2546 * gc.c, gc.h (scm_gc_yield): New variable.
2547 (adjust_gc_trigger): Use scm_gc_yield.
2548 (alloc_some_heap): Use scm_gc_yield instead of
2549 scm_gc_cells_collected.
2551 * coop-threads.c: Addd #include "root.h", #include "strings.h".
2553 * debug.c: Added #include "root.h". (Thanks to Thien-Thi Nguyen.)
2555 * gc.c (scm_gc_for_newcell, adjust_gc_trigger): Improved GC
2556 trigger adjustmeant: Take yield (freed cells) for all freelists
2558 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Tuned
2559 to 50000 cell heap with 45% trigger.
2560 (scm_gc_cells_collected): Reintroduced.
2561 (SCM_HEAP_SIZE): New macro.
2562 (scm_gc_sweep): Reintroduced correct computation of
2563 scm_cells_allocated.
2564 (scm_freelist_t): Corrected commentary for field `cluster_size':
2565 Clustersize counts objects, not cells; New member
2566 `clusters_allocated'.
2568 2000-03-19 Michael Livshin <mlivshin@bigfoot.com>
2570 * *.[hc]: add Emacs magic at the end of file, to ensure GNU
2573 2000-03-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2575 * threads.h: Added #include "libguile/throw.h". (Thanks to
2578 2000-03-18 Michael Livshin <mlivshin@bigfoot.com>
2580 * tags.h: (SCM_DOUBLE_CELLP, SCM_NDOUBLE_CELLP): new macros (bad
2581 names, anyone got any better ones?)
2583 * gc.h: (typedef struct scm_freelist_t) remove from here.
2585 * gc.c: (CELL_UP, CELL_DN) made these macros take additional
2586 parameter (the span).
2587 (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK) new macros.
2588 (typedef struct scm_freelist_t) moved here from gc.h, it had no
2589 business being externally visible.
2590 (typedef struct scm_heap_seg_data_t) renamed from
2591 scm_heap_seg_data, to be style-compliant.
2592 (scm_mark_locations) if the possible pointer points to a
2593 double-cell, check that it's properly aligned.
2594 (init_heap_seg) align double-cells properly, work with the
2595 assumption that the segment size divides cleanly by cluster size.
2596 (round_to_cluster_size) new function.
2597 (alloc_some_heap, make_initial_segment) use round_to_cluster_size
2598 to satisfy the new init_heap_seg invariant.
2600 2000-03-18 Dirk Herrmann <D.Herrmann@tu-bs.de>

2657 2000-03-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2659 * gc.c, gc.h: Cleanup of the change of 2000-03-15.
2660 Cluster sizes are now independent of GC trigger values.
2661 GUILE_GC_TRIGGER_n can now specify a relative trigger value:
2662 A negative integer gives fraction of total heap size in percent.
2663 (SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Default values set to -40.
2665 * init.c (scm_boot_guile_1): Introduced new variable
2666 GUILE_MAX_SEGMENT_SIZE; New environment variable names:
2667 GUILE_INIT_SEGMENT_SIZE_1, GUILE_GC_TRIGGER_1,
2668 GUILE_INIT_SEGMENT_SIZE_2, GUILE_GC_TRIGGER_2
2670 2000-03-16 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2672 * __scm.h (GC_FREE_SEGMENTS): Disable this until we have made
2673 freeing of segment work with the new GC scheme. (Thanks to
2674 Michael Livshin.) Oops, also happened to make GUILE_NEW_GC_SCHEME
2675 the default, but I'll let this change stay in CVS Guile since this
2676 code is not expected to contain serious bugs.
2678 2000-03-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2680 * gc.c, gc.h (scm_map_free_list): Define also if GUILE_DEBUG is
2682 (scm_free_list_length): New procedure (GUILE_DEBUG).
2683 Fixed a small but serious bug introduced by the previous change.
2685 * gc.c (scm_gc_sweep): Moved variable n_objects to inner sweep
2686 loop and declare as register.
2688 * gc.c (scm_gc_sweep): Sigh... forgot to clear private freelists
2691 Wed Mar 15 08:27:04 2000 Greg J. Badros <gjb@cs.washington.edu>
2693 * fluids.c: Docstring patch from Keisuke Nishida. Some
2694 reindentation, too, and a couple formals renamed. Should
2695 fluid-set! return UNSPECIFIED instead of a value?
2697 Wed Mar 15 08:24:58 2000 Greg J. Badros <gjb@cs.washington.edu>
2699 * Makefile.am: Separate out DOT_X_FILES and DOT_DOC_FILES, and
2700 generate the latter from the concrete listing of the former. Then
2701 make guile-procedures.txt depend on DOT_DOC_FILES instead of
2702 *.doc, so that rebuilding it works.
2704 Wed Mar 15 08:12:14 2000 Greg J. Badros <gjb@cs.washington.edu>
2706 * libguile.h: Include libguile/validate.h. Thanks Keisuke Nishida!
2708 * guile-snarf.awk.in: Replace docstring line-ending \n" and \n\n"
2709 with nothing and \n, respectively. Thanks Keisuke Nishida for
2710 noticing this problem.
2712 2000-03-15 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2714 * __scm.h (GUILE_NEW_GC_SCHEME): Define this if you want to test a
2715 new way of allocating heap. It makes Guile fast, but still
2718 * gc.c, gc.h, pairs.h, init.c: Implementation of a new way of
2719 allocating heap. The basic idea is to trigger GC every Nth
2720 allocated cell and grow heap when free list runs out. The scheme
2721 has been extended so that GC isn't triggered until all remaining
2722 cells are used. The implementation is also prepared for
2723 development in the direction of POSIX threads.
2725 * gc.c (SCM_EXPHEAP): In order to grow by a factor of 1.5,
2726 SCM_EXPHEAP should return half of the heap size.
2728 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2730 The following change to init.c is only enabled if Guile was
2731 configured with --enable-guile-debug.
2733 * init.c (scm_i_getenv_int): New function.
2734 (scm_boot_guile_1): Use the environment variables
2735 GUILE_INIT_HEAP_SIZE, GUILE_INIT_HEAP_SIZE2 to select heap size if
2736 they exist. (This may be replaced by a Scheme level mechanism in
2739 * objprop.c (s_scm_set_object_property_x): Use scm_assq instead of
2740 scm_assoc. (Thanks to Keisuke Nishida.)
2742 2000-03-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2744 * eval.c, lang.c, lang.h (scm_lisp_nil, scm_lisp_t): Renamed from
2745 scm_nil, scm_t. (Thanks to Keisuke Nishida.)
2747 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2749 * init.c (scm_boot_guile_1): Use same initial segment size for
2750 1-word and 2-word segments. Having the smaller size causes Guile
2751 to GC too often. Obviously something needs to be done to allow
2752 for a smaller 2-word segment without this to happen. (The amount
2753 of heap for each type should be automatically adapted to the
2754 application somehow.)
2756 [Almost all of these changes should be documented in the NEWS
2759 * gc.h (scm_freelist_t): New type.
2761 * pairs.h (SCM_NEWCELL, SCM_NEWCELL2): Use new style freelists.
2763 * gc.c (SCM_INIT_HEAP_SIZE): Changed from 32768 --> 40000 so that
2764 all of Guile basics fits into one segment and there suitable room
2766 (SCM_EXPHEAP): Now takes an argument. Grow by a factor of 1.5
2768 (scm_freelist, scm_freelist2): Now of type scm_freelist_t.
2769 Freelists now contains information about object span, cells
2770 collected and amount of cells in heap segments belonging to the
2772 (scm_heap_size, scm_gc_cells_collected): Removed.
2774 * init.c (scm_boot_guile_1): Make 2-word segment 8K (512 cells).
2776 * Makefile.am (libguile_la_LDFLAGS): Bumped library version
2779 * __scm.h eq.c, eval.c, gc.c, gc.h, gh_data, hash.c, numbers.c,
2780 numbers.h, objects.c, ramap.c, random.c, unif.c, unif.h: Extensive
2781 rewrite of handling of real and complex numbers.
2782 (SCM_FLOATS, SCM_SINGLES): These #ifdef conditionals have been
2783 removed along with the support for floats. (Float vectors are
2786 * tags.h (scm_tcs_bignums): Removed.
2787 (scm_tc16_bigpos, scm_tc16_bigneg): Replaced by scm_tc16_big.
2788 Use SCM_BIGSIGN(x) to test for sign!
2789 (scm_tc16_big): The new bignum type.
2790 (SCM_REAL_PART, SCM_IMAG_PART): Removed.
2792 * numbers.h (SCM_BIGSIGN): Sign moved to bit 16.
2793 (scm_makdbl): Deprecated.
2794 (SCM_NEWREAL, SCM_NEWCOMPLEX): New macros.
2795 (SCM_SINGP): Deprecated.
2797 (SCM_INEXP, SCM_CPLXP): Deprecated.
2798 (SCM_INEXACTP, SCM_COMPLEXP): New macros.
2799 (SCM_COMPLEX_REAL, SCM_COMPLEX_IMAG): Renamed from
2800 SCM_REAL, SCM_IMAG (and now only valid for complex numbers).
2801 (SCM_REAL, SCM_IMAG): New, *deprecated*, selectors which work both
2802 for doubles and complex numbers.
2803 (SCM_REAL_VALUE): New selector for doubles.
2804 (scm_double_t, scm_complex_t): New types.
2807 * numbers.c (scm_floprint, scm_floequal): Removed.
2808 (scm_print_real, scm_print_complex, scm_real_equalp,
2809 scm_complex_equalp): New functions.
2811 * unif.c (scm_makflo): Removed.
2813 * smob.h (SCM_SMOB_PREDICATE): New macro.
2814 (SCM_NEWSMOB2, SCM_RETURN_NEWSMOB2, SCM_NEWSMOB3,
2815 SCM_RETURN_NEWSMOB3): New macros.
2817 1999-11-21 Michael Livshin <mlivshin@bigfoot.com>
2819 The following changes implement primitive support for double cells
2820 (i.e. four-word cells) and change the representation of some
2821 things to multi-cells instead of cons+malloc. (Applied and
2824 * pairs.h (SCM_NEWCELL2): double-cell variants of SCM_NEWCELL.
2825 (SCM_CELL_WORD, SCM_CELL_WORDLOC, SCM_SET_CELL_WORD): primitive
2826 multi-cell access macros (used by the ones below).
2827 (SCM_CELL_WORD[0-3], SCM_SET_CELL_WORD[0-3]): multi-cell access
2830 * gc.c (scm_freelist2): multi-cell freelists.
2831 (inner_map_free_list): map_free_list, parameterized on ncells.
2832 "nn cells in segment mm" was misleading for ncells > 1; changed to
2833 "objects". still print cells too, though.
2834 (scm_map_free_list): rewritten using inner_map_free_list.
2835 (scm_check_freelist): get freelist as parameter, since now we have
2837 (scm_debug_newcell2): multi-cell variants of
2839 (scm_gc_for_newcell): take ncells and freelist pointer as
2841 (scm_gc_mark): add case for tc7_pws (procedures with setters are
2843 (scm_gc_sweep): don't free the float data, since it's not malloced
2845 (init_heap_seg): didn't understand what n_new_objects stood for,
2846 so changed to n_new_cells.
2847 (make_initial_segment): new function, makes an initial segment
2848 according to given ncells.
2849 (scm_init_storage): call make_initial_segment, for ncells={1,2,3}.
2851 * numbers.c (scm_makdbl): no malloc'ing needed, so the
2852 {DEFER,ALLOW}_INTS thing removed.
2854 * numbers.h (struct scm_dbl): changed to represent a double cell,
2855 with the number in the second half.
2857 * dynwind.c: changed the wind-guards representation to double
2860 * procs.c, procs.h: changed the procedure-with-setter representation
2863 * async.c, async.h: made async representation a double cell.
2865 * dynl.c: made dynamic_obj representation a double cell.
2867 2000-03-13 Gary Houston <ghouston@arglist.com>
2869 * ports.c (flush_void_port): renamed to flush_port_default.
2870 (end_input_void_port): renamed to end_input_default.
2872 * init.c (scm_standard_stream_to_port): create a void port instead
2873 of opening /dev/null if the standard file descriptors are bad.
2874 advantages: no portability problems, doesn't waste a file descriptor,
2875 simplifies the code (thanks to Marius for the idea).
2877 * vports.c (s_scm_make_soft_port): call scm_port_non_buffer.
2879 * void ports: make reading from a void port give EOF instead of
2881 * ports.c (s_scm_sys_make_void_port): modified docstring.
2882 (fill_input_void_port): new proc.
2883 (scm_init_ports): set up fill_input_void_port.
2884 * ports.c (scm_port_non_buffer): new proc.
2885 (scm_void_port): call scm_port_non_buffer.
2887 * fports.c (scm_setvbuf): docstring: remove the fcntl documentation
2888 which was incorrectly appended.
2890 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2892 * guile-doc-snarf.in: Don't use absolute path for `sed'. (Note
2893 that we can't use autoconf for this. Autoconf itself relies on
2894 the existence of `sed' somewhere on your path.) (Thanks to Dirk
2897 2000-03-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2899 * Makefile.am (libguile_la_SOURCES): Moved iselect.c here from
2900 EXTRA_libguile_la_SOURCES.
2902 * iselect.h: Always declare scm_internal_select.
2904 * iselect.c (scm_internal_select): Added SCM_ASYNC_TICK at the
2905 end. Also let scm_internal_select be a real function also when
2908 * __scm.h (SCM_TICK): Oops! Forgot to put SCM_ASYNC_TICK here...
2910 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2912 * __scm.h (SCM_ALLOW_INTS, SCM_REALLOW_INTS): Removed call to
2913 SCM_ASYNC_TICK. (This is a preparation for POSIX threads support,
2914 and kind of an experiment: Will this cause problems?)
2916 Sun Mar 12 13:26:30 2000 Greg J. Badros <gjb@cs.washington.edu>
2918 * Makefile.am: Added *.doc to DISTCLEANFILES.
2920 2000-03-12 Gary Houston <ghouston@arglist.com>
2922 * fports.c (scm_fdes_to_port): call fcntl F_GETFL to test that
2923 the fdes is valid before doing anything else. check that
2924 the file descriptor supports the modes required.
2925 (scm_fport_buffer_add): don't throw an error if fstat doesn't
2926 work: just use the default buffer size.
2928 * throw.c: change an outdated comment about scm_internal_catch
2929 BODY: it doesn't take a jumpbuf arg.
2931 * init.c (scm_standard_stream_to_port): install a handler in case
2932 scm_fdes_to_port throws an error. don't check here whether the
2933 file descriptor is valid, since scm_fdes_to_port will do that.
2934 set the revealed count depending on whether the port got the
2935 standard file descriptor.
2936 (stream_body_data): new type.
2937 (stream_body, stream_handler): new procs.
2939 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2941 * stacks.c, stacks.h, struct.c, tags.h, unif.c (scm_bits_t):
2942 Renamed from SCMWORD.
2944 * tags.h (SCM_NCELLP): Removed (SCMWORD).
2946 * arbiters.c (SCM_ARB_LOCKED): Use SCM_UNPACK_CAR.
2948 * async.c, boolean.h, debug.c, dynl.c, dynwind.c, eval.c, eval.h,
2949 feature.h, filesys.h, fluids.h, fports.c, fports.h, gc.c, gc.h,

2954 throw.c, unif.c, unif.h, variable.h, vectors.h, weaks.c,
2955 weaks.h (SCM_PACK, SCM_UNPACK, SCM_UNPACK_CAR): Renamed from
2956 SCM_ASSCM, SCM_ASWORD, SCM_CARW).
2958 * numbers.h (SCM_SRS, SCM_INUM): Corrected SCM_ASSCM/ASWORD fixes.
2960 * alist.c, eval.c, net_db.c, posix.c, print.c, snarf.h, struct.c,
2961 tags.h: Fixed copyright notices.
2963 * struct.c, coop-threads.c: SCM_ASSCM/ASWORD fixes.
2965 2000-03-12 Marius Vollmer <mvo@zagadka.ping.de>
2967 * init.c (scm_standard_stream_to_port): Check whether the file
2968 descriptor is valid and substitute "/dev/null" when not.
2970 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2972 * coop-defs.h (struct timespec): Conditionally defined.
2974 * coop.c (coop_condition_variable_timed_wait_mutex): Use ETIMEDOUT
2977 * readline.c (match_paren): Bugfix: First arg to select is not
2978 number of descriptors but the number of the highest descriptor +
2981 This is a preliminary attempt at a cleanup of the threads support
2982 code. It moves things to better places, makes arguments more
2983 consistent with the POSIX API (which is used in GNOME's glib), and
2984 adds new functionality.
2986 * readline.c (scm_init_readline): Added new arg to scm_init_mutex.
2988 * coop-defs.h (scm_mutex_trylock): New macro: alias for
2990 (scm_cond_init): Changed definition to
2991 coop_new_condition_variable_init.
2993 * coop.c: #include <errno.h>
2994 (coop_timeout_qinsert): Moved here from iselect.c
2995 (coop_new_mutex_init, coop_new_condition_variable_init): New
2996 functions. The strange names are temporary. Use scm_mutex_init
2997 and scm_cond_init instead.
2998 (coop_mutex_trylock): New function. Uses errno.h:EBUSY. errno.h
2999 is ANSI C, but should we check for individual error codes in
3001 (coop_condition_variable_timed_wait_mutex): New function.
3002 (coop_key_create, coop_setspecific, coop_getspecific,
3003 coop_key_delete): New functions.
3005 * iselect.c (coop_timout_qinsert): Moved to coop.c
3007 2000-03-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3009 * pairs.h (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR,
3010 SCM_SETOR_CDR): Corrected SCM_ASSCM/WORD fixes.
3012 * tags.h (SCM_VOIDP_TEST): Renamed from VOIDP_TEST.
3015 * objects.h (SCM_CLASS_FLAGS, SCM_OBJ_CLASS_FLAGS,
3016 SCM_SET_CLASS_INSTANCE_SIZE), struct.h (SCM_STRUCT_VTABLE_DATA),
3017 proc.h (SCM_CLOSCAR): SCM_ASSCM/WORD fixes.
3019 * eval.c (scm_lookupcar1): Inserted SCM_ASWORD in expressions
3022 2000-03-11 Dale P. Smith <dpsm@en.com>, applied by Greg J. Badros, <gjb@cs.washington.edu>
3024 * numbers.c (scm_copy_big_dec, scm_copy_smaller, scm_big_ior,
3025 scm_big_xor, scm_big_and, scm_big_test): Added new lowlevel bignum
3026 logical functions from SCM.
3028 (logand, logior, logxor, logtest, logbit?): Extended scheme
3029 logical functions to use bignums from SCM.
3031 (lognot): Removed call to `SCM_VALIDATE_INUM' that prevented
3032 lognot from using bignums.
3034 Thu Mar 9 11:33:25 2000 Greg J. Badros <gjb@cs.washington.edu>
3036 * vectors.h (SCM_VELTS_AS_STACKITEMS): Added this macro to help in
3037 eliminating some warnings.
3039 * unif.c, strports.c, print.c, options.c: Fix some warnings on
3042 * gc.c, gc.h: Added scm_return_first_int(), and added comment re:
3043 what the scm_return_first* functions do.
3045 2000-03-09 Han-Wen Nienhuys <hanwen@cs.uu.nl>, applied by Greg J. Badros, <gjb@cs.washington.edu>
3047 * libguile/*.[ch]: make a distinction between SCM as a generic
3048 name for a Scheme object (now a void*), and SCM as 32 bit word for
3049 storing tags and immediates (now a long int). Introduced
3050 SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious
3051 code in the process: arbiter.c (use macros), unif.c (scm_array_p),
3053 Wed Mar 8 10:15:59 2000 Greg J. Badros <gjb@cs.washington.edu>
3055 * numbers.c: Use SCM_VALIDATE_LONG_COPY, and longs, not ints, in
3056 various logXXX primitives. Thanks Eric Moore!
3058 Tue Mar 7 08:05:22 2000 Greg J. Badros <gjb@cs.washington.edu>
3060 * run-test, remaining-docs-needed: Added these scripts. The
3061 second one is only temporary until the docstring additions are
3062 complete. run-test may best live on, but is here mostly for
3063 convenience and awareness for now.
3065 * hash.c: Docs, minor cleanup patch from Dirk Herrman.
3067 Thu Mar 2 16:06:58 2000 Greg J. Badros <gjb@cs.washington.edu>
3069 * error.h, error.c: Added `scm_wrong_type_arg_msg' to support
3070 displaying the expected type. Use SCM_LISTn in a couple places
3071 instead of scm_cons-ing by hand.
3073 * __scm.h: Added SCM_ASSERT_TYPE macro.
3075 * validate.h, scm_validate.h: Added the former, as a renamed
3076 version of the latter with SCM_ASSERT_TYPE used in
3077 SCM_MAKE_VALIDATE (instead of just SCM_ASSERT)
3079 * Makefile.am: Rename scm_validate.h to validate.h.
3081 * *.c, *.h: Include validate.h, not scm_validate.h (old name's
3082 prefix was superfluous).
3084 Thu Mar 2 15:33:12 2000 Greg J. Badros <gjb@cs.washington.edu>
3086 * hashtab.c: Improved documentation for lots of functions. Added
3087 handwritten docs for `hash-fold'.
3089 Thu Mar 2 15:13:25 2000 Greg J. Badros <gjb@cs.washington.edu>
3091 * list.c: Added hand-written docs for `del{q,v,ete}1!'.
3093 Thu Mar 2 12:38:30 2000 Greg J. Badros <gjb@cs.washington.edu>
3095 * list.c: Moved append docs to append! Thanks Dirk Hermann. Also,
3096 added append docs from R4RS.
3098 * strings.c: Docstring typo fix, + eliminate unneeded IMP tests.
3099 Thanks Dirk Hermann!
3101 * chars.h: Provide SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR and
3102 deprecate SCM_ICHRP, SCM_ICHR, SCM_MAKICHR. Thanks Dirk Hermann!
3104 * *.h, *.c: Use SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR throughout.
3105 Drop use of SCM_P for function prototypes... assume an ANSI C
3106 compiler. Thanks Dirk Hermann!
3108 Sat Feb 19 12:20:12 2000 Greg J. Badros <gjb@cs.washington.edu>
3110 * ports.c: Made `set-port-column!' and `set-port-line!' each
3111 return SCM_UNSPECIFIED instead of a (not-scheme-object) integer
3112 that caused a seg fault. Also fixed `set-port-column!'s
3113 docstring. Thanks Han-Wen Nienhuys for finding the bug!
3115 Sun Feb 13 19:11:42 2000 Greg J. Badros <gjb@cs.washington.edu>
3117 * arbiters.c, eq.c, gc.c, guardians.c, list.c, ports.c, print.c,
3118 regex-posix.c, scmsigs.c, stime.c, strings.c, variable.c, stime.c,
3119 strings.c, variable.c: Added lots of documentation, cleaned up
3120 some existing documentation. Occasionally changed formal params
3121 to match docs. Also folded an #ifdef into the inners of a
3122 primitive instead of having two copies of the primitive
3123 (`get-internal-real-time', from stime.c)
3125 Sun Feb 13 18:12:19 2000 Greg J. Badros <gjb@cs.washington.edu>
3127 * ports.c: Added docs for primitives missing them. Written by
3130 Sun Feb 13 09:40:36 2000 Greg J. Badros <gjb@cs.washington.edu>
3132 * guile-doc-snarf.in: Use ${AWK} -f guile-func-name-check, not
3133 just execing guile-func-name-check. Thanks Michael Livshin!
3135 Thu Feb 10 11:43:23 2000 Greg J. Badros <gjb@cs.washington.edu>
3137 * guile-snarf.awk.in: Tweak to work with Sun/HP awk, removed some
3138 dead code. Patch from Michael Livshin.
3140 * guile-doc-snarf.in: Tweak to work with Sun/HP sh. Patch from
3143 2000-02-09 Gary Houston <ghouston@arglist.com>
3145 * init.c (scm_init_standard_ports): when stdout is a tty, make the
3146 current-output-port unbuffered by default. this is less confusing
3147 for interactive use. it was line-buffered because of a
3148 performance problem with unbuffered ports, but I think it will be
3151 2000-02-08 Gary Houston <ghouston@arglist.com>
3153 * __scm.h: don't define long_long or ulong_long if HAVE_LONG_LONGS
3156 * stime.c (scm_localtime, scm_mktime): if neither HAVE_TM_ZONE nor
3157 HAVE_TZNAME are defined, use an empty string instead of giving two
3158 spurious compile-time errors.
3160 Tue Feb 8 13:57:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3162 * ports.c: Doc patches from Richard Kim. Pasted from MIT Scheme.
3165 Mon Feb 7 09:07:31 2000 Greg J. Badros <gjb@cs.washington.edu>
3167 * macros.c: Doc patches from Richard Kim. Pasted from scm.texi.
3169 Sun Feb 6 20:26:21 2000 Greg J. Badros <gjb@cs.washington.edu>
3171 * pairs.c: Doc patches from Richard Kim. Pasted from MIT Scheme
3172 (which is GNU GPL'd).
3174 2000-01-31 Gary Houston <ghouston@arglist.com>
3176 * strings.h: don't use SCM_P. don't include <string.h>.
3177 * error.c, gh_data.c, ports.c, script.c, strop.c: include <string.h>.
3179 * strings.c (scm_string_ref): make the 2nd argument compulsory.
3180 previously it defaulted to zero for no good reason that I can see.
3181 use a local variable for SCM_INUM (k). replace
3182 SCM_VALIDATE_INUM_DEF with SCM_VALIDATE_INUM_COPY.
3184 (scm_makfromstr): cosmetic changes.
3186 (scm_string): Accept only chars in the list, not strings, for
3187 conformance to R5RS (particularly for list->string, which is
3188 supposed to be the inverse of string->list.) remove
3189 SCM_DEFER_INTS/SCM_ALLOW_INTS, which is unnecessary since
3190 scm_makstr handles the cell allocation. when reporting wrong-type
3191 arg, don't report the position as 1.
3193 * posix.c (scm_init_posix): intern PIPE_BUF if it's defined.
3195 2000-01-29 Gary Houston <ghouston@arglist.com>
3197 * posix.c (scm_pipe): rewrote the docstring.
3199 * filesys.c (scm_select, retrieve_select_type, get_element,
3200 fill_select_type, set_element): modified so that Scheme
3201 "select" tests port buffers for the ability to provide input
3202 or accept output. Previously only the underlying file descriptors
3203 were checked. Rewrote the docstring.
3205 Thu Jan 27 10:14:25 2000 Greg J. Badros <gjb@cs.washington.edu>
3207 * vectors.c, symbols.c, strorder.c: Documentation cut and pasted
3208 from Gregg Reynolds. Thanks Gregg!
3210 Thu Jan 27 09:59:38 2000 Greg J. Badros <gjb@cs.washington.edu>
3212 * strop.c (scm_i_index): Obfuscated commented-out SCM_DEFINE by
3213 adding "x" prefix to the line so that guile-func-name-check
3214 doesn't complain unnecessarily.
3216 Wed Jan 26 17:33:52 2000 Greg J. Badros <gjb@cs.washington.edu>
3218 * throw.c: Factor out an #ifdef/#else/#endif choice more finely
3219 for maintainability.
3221 * strop.c: Documentation added by Gregg A. Reynolds. Pasted in
3224 Wed Jan 26 10:02:11 2000 Greg J. Badros <gjb@cs.washington.edu>
3226 * tag.c: Added doc for `tag', but mark as deprecated since Mikael
3227 suggests removing tag.c altogether (and using a new `class-of'
3230 * strings.c: Added documentation from Gregg A. Reynolds. Edited
3231 a bit by me to use FOO instead of @var{foo} and to have the
3232 summary come before preconditions on input. Also dropped trailing
3235 * gsubr.c: Do not use SCM_DEFINE for `gsubr-apply'. Register the
3236 function with scm_make_subr_opt w/ last arg of 0 so it is not
3237 visible at the Scheme level. Mikael says that this is the right
3238 thing because the first arg to the proc is the guts of a compiled
3239 closure and shouldn't be exposed to the Scheme level.
3241 Tue Jan 25 17:15:47 2000 Greg J. Badros <gjb@cs.washington.edu>
3243 * sort.c: typo in comment fixed.
3245 * keywords.c: Added documentation.
3247 * guardians.c: Added documentation (could be better).
3249 * gc.c: Added docs for gc-set-debug-check-freelist.
3251 * eq.c: Added docs for eq?, eqv? equal? abridged from R4RS.
3253 * boolean.c: Added docs for `not', `boolean?' (by hand).
3255 Tue Jan 25 13:28:56 2000 Greg J. Badros <gjb@cs.washington.edu>
3257 * random.c: Added documentation, from SLIB page:
3258 http://angela.ctrl-c.liu.se/~calle/scheme/slib_toc.html
3260 Mon Jan 24 17:50:20 2000 Greg J. Badros <gjb@cs.washington.edu>
3262 * variable.c, version.c: Added documentation, written by hand
3263 since I could not find anything already written that was
3266 2000-01-23 Gary Houston <ghouston@arglist.com>
3268 * filesys.c (scm_chown): omit port/fdes support if HAVE_FCHOWN is
3269 not defined (thanks to Richard Y. Kim).
3271 Thu Jan 20 13:00:38 2000 Greg J. Badros <gjb@cs.washington.edu>
3273 * Makefile.in: Removed, this is auto-generated.
3275 Thu Jan 20 11:33:47 2000 Dirk Hermann <dirk@ida.ing.tu-bs.de> --applied 01/20/00 gjb
3277 * list.c: Put some variable initialization code at the point of
3278 declaration; Added a comment for list*; Formatting changes.
3280 * load.c: use SCM_NNULLP to make sure the end of a list is not
3283 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3285 * backtrace.c (scm_display_error_message): Bugfix: Don't use
3286 result of scm_list_p as C boolean.
3287 (scm_display_error_message, scm_set_print_params_x): Use new
3288 validation macros. (Thanks to Dirk Herrmann.)
3290 * net_db.c (scm_resolv_error): Cast result from hstrerror.
3292 * strports.c (st_end_input): Inserted parenthesis to get operator
3295 * list.h (scm_init_list): Removed SCM_P around prototypes.
3297 * fports.c, list.c, numbers.c, ports.c, stime.c, symbols.c,
3298 filesys.c, posix.c: Converted docstrings to ANSI C format and
3299 escaped " occurring inside string literals.
3301 Tue Jan 18 13:21:08 2000 Mikael Djurfeldt <mdj@r11n07-s.pdc.kth.se>
3303 * posix.c (scm_mknod): Escape " occuring inside docstring.
3305 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3307 * alist.c, chars.c, debug.c, dynl.c, dynwind.c, error.c, eval.c,
3308 evalext.c, filesys.c, gc.c, hash.c, hashtab.c, ioext.c,
3309 keywords.c, list.c, load.c, macros.c, net_db.c, numbers.c,
3310 objprop.c, ports.c, posix.c, print.c, procprop.c, procs.c,
3311 ramap.c, regex-posix.c, root.c, scmsigs.c, simpos.c, socket.c,
3312 stacks.c, stime.c, strings.c, strop.c, strports.c, struct.c,
3313 symbols.c, throw.c, unif.c, vectors.c, version.c, vports.c,
3314 weaks.c: Converted docstrings to ANSI C format.
3316 * filesys.c (scm_chmod), simpos.c (scm_system), version
3317 (scm_version), vports (scm_make_soft_port): Escape " occuring
3320 Mon Jan 17 11:41:22 2000 Greg J. Badros <gjb@cs.washington.edu>
3322 * scm_validate.h: Added SCM_VALIDATE_ULONG_COPY,
3323 SCM_VALIDATE_LONG_COPY
3325 * numbers.c: Use SCM_VALIDATE_ULONG_COPY, instead of
3326 SCM_VALIDATE_INUM_COPY to let bigger numbers be used. Rename a
3327 couple of formal arguments (and fix their uses) to make arguments
3328 match the documentation.
3330 2000-01-14 <mstachow@alum.mit.edu>
3332 * Makefile.am: Augment path when running guile-doc-snarf so
3333 guile-func-name-check is found.
3335 Fri Jan 14 09:34:55 2000 Greg J. Badros <gjb@cs.washington.edu>
3337 * scm_validate.h (SCM_NUM2LONG_DEF): Fix this macro to just use
3338 def, not SCM_MAKINUM(def); thanks Janis Bzerins!
3340 Wed Jan 12 00:06:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3342 * net_db.c (s_scm_inet_makeaddr): Use SCM_NUM2ULONG since that's
3343 the way guile-1.3.4 worked, but #if 0 out the version using
3344 SCM_VALIDATE_INUM_COPY for stricter testing.
3346 Tue Jan 11 18:24:18 2000 Greg J. Badros <gjb@cs.washington.edu>
3348 * guile-doc-snarf.in: Use new $fullfilename for running
3349 guile-func-name-check, and put "$fullfilename" and "$filename" in
3350 quotes at uses to make sure re-splitting on whitespace does not
3351 occur (so filenames w/ embedded whitespace would work okay, though
3352 I sure hope we never have to deal with that! :-) ). Thanks to
3353 Mikael for pointing out the source_dir != build_dir was broken.
3355 Tue Jan 11 17:42:40 2000 Greg J. Badros <gjb@cs.washington.edu>
3357 * scm_validate.h: Added SCM_NUM2LONG_DEF macro. Make
3358 SCM_OUT_OF_RANGE use SCM_MAKINUM, not scm_long2num. Added
3359 SCM_COERCE_ROSTRING macro. Added SCM_VALIDATE_NONEMPTYLIST
3360 macro. Fix SCM_VALIDATE_STRINGORSUBSTR macro to not use SLOPPY
3363 * ports.c (scm_port_closed_p): Validate that the arg is a PORT,
3364 then return whether it's an open port (was validating that it was
3365 an open port -- this was a bug I introduced back in December, but
3366 my careful reading of diffs caught it).
3368 * numbers.c: Recombine the two conditional-compilation paths for
3369 all the log* primitives -- they were split based on #ifndef
3370 scm_long2num; factored out a SCM_LOGOP_RETURN macro, and fixed
3371 some bugs and inconsistencies in the two sets of implementations.
3372 (scm_lognot) Fixed *atrocious* re-use of a SCM as an integer!
3374 * ioext.c: Use SCM_ASSERT_RANGE in a couple places, and
3375 SCM_VALIDATE_INUM_COPY once where it should've been used.
3377 * fluids.c (scm_internal_with_fluids): Use
3378 SCM_VALIDATE_LIST_COPYLEN.
3380 * filesys.c: Use SCM_NUM2LONG instead of SCM_VALIDATE_INUM_COPY;
3381 this is questionable as it relaxes type safety, but other changes
3382 were useful and all SCM_NUM2LONG's should probably be
3383 revisited. Use SCM_OUT_OF_RANGE, SCM_WRONG_TYPE_ARG.
3385 * evalext.c: line-break change on 1 line.
3387 * eval.c (nconc2last): Takes a non-empty list as its first
3388 argument, not just a list.
3390 * dynl.c: Use new SCM_COERCE_ROSTRING macro.
3392 Tue Jan 11 15:44:23 2000 Greg J. Badros <gjb@cs.washington.edu>
3394 * dynl.c, feature.c, filesys.c, fports.c, list.c, load.c,
3395 net_db.c, sort.c, stacks.c, unif.c: Use SCM_WTA, SCM_MISC_ERROR
3398 * symbols.c (scm_sysintern0): Fixed the function name in a
3399 scm_misc_error invocation.
3401 * print.c (scm_simple_format): Do not need SCM_COERCE_SUBSTR, and
3402 use scm_return_first to ward off latent GC bug that Mikael caught.
3404 * async.c: Use SCM_VALIDATE_ASYNC_COPY one place where it wasn't
3405 used before but should've been.
3407 2000-01-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3409 * snarf.h (SCM_PROC1): Replaced SCM (*) (...) with
3410 SCM_FUNC_CAST_ARBITRARY_ARGS.
3412 Tue Jan 11 13:44:07 2000 Greg J. Badros <gjb@cs.washington.edu>
3414 * guile-func-name-check.in: Added this script to statically check
3415 #define FUNC_NAME, #undef FUNC_NAME in the source.
3417 * sort.c, posix.c: Fix #undef FUNC_NAME lines to not have trailing
3418 redundant comment, semicolon; caught by new guile-func-name-check
3421 * debug.c: Fix mistaken #define FUNC_NAME for scm_make_iloc.
3422 Caught by new guile-func-name-check-script.
3424 * Makefile.am: Added guile-func-name-check to bin_SCRIPTS
3426 * ramap.c: Fix #if 0'd out code to be syntactically acceptable to
3427 guile-func-name-check.
3429 * guile-doc-snarf.in: Run guile-func-name-check on the file before
3432 Tue Jan 11 11:31:10 2000 Greg J. Badros <gjb@cs.washington.edu>
3434 * fports.c, ports.c, ports.h, strports.c, vports.c: Make write
3435 port function take const void*, not void*.
3437 Tue Jan 11 11:18:07 2000 Greg J. Badros <gjb@cs.washington.edu>
3439 * scm_validate.h, chars.c, ports.c, print.c, read.c, strings.c,
3440 strop.c: Use SCM_VALIDATE_ICHR, SCM_VALIDATE_ICHR_COPY instead of
3441 SCM_VALIDATE_CHAR, SCM_VALIDATE_CHAR_COPY. Change made for
3442 consistency with the other macros dealing with immediate
3443 characters. (Similar to INT -> INUM change a week or so ago).
3445 Tue Jan 11 10:41:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3447 * dynl.c, error.c, eval.c, feature.c, filesys.c, fports.c, list.c, load.c,
3448 net_db.c, read.c, socket.c: Update error messages to use ~A for
3449 %s, ~S for %S to work with new `simple-format' format and be
3450 standardized better.
3452 * print.h, print.c (scm_simple_format): Added `simple-format'
3453 primitive. It's the old scm_display_error, with ARGS now a rest
3454 parameter, and the destination first instead of last (and a couple
3455 new capabilities inspired by `format' -- #t as destination means
3456 current-output-port, #f means return the formatted text as a
3459 * gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
3461 * backtrace.c (scm_display_error_message): Rewrote to use
3462 scm_simple_format() procedure.
3464 * __scm.h: Added commented-out #define of GUILE_DEBUG_FREELIST
3466 2000-01-09 Marius Vollmer <mvo@zagadka.ping.de>
3468 Finally applied the libltdl patch from Thomas Tanner, with slight
3471 * DYNAMIC-LINKING: Removed because it is obsolete.
3472 * dynl.c: Use ANSI prototypes.
3473 (sysdep_dynl_link): Use lt_dlopenext instead of lt_dlopen.
3474 * scmconfig.h.in: Do not change, as it is automatically generated.
3476 1999-07-25 Thomas Tanner <tanner@ffii.org>
3478 * dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c: deleted
3480 * Makefile.am: likewise, add INCLTDL (libltdl headers) to
3481 INCLUDES, set dlpreopened files in LDFLAGS, link libguile
3483 * dynl.c: use libltdl if DYNAMIC_LINKING is enabled,
3484 * guile.c: register preloaded modules
3485 * scmconfig.h.in: remove obsolete symbols
3487 2000-01-09 Gary Houston <ghouston@arglist.com>
3489 * These changes should make it unnecessary to call tzset from
3490 Scheme after modifying the TZ environment variable, even if the
3491 system date facilities cache the value.
3492 * stime.c (setzone, scm_localtime): added comments.
3493 (tzset): don't define a noop tzset macro if HAVE_TZSET not defined.
3494 (setzone): don't call tzset.
3495 (restorezone): call tzset only if HAVE_TZSET is defined.
3496 (scm_tzset): don't define if HAVE_TZSET not defined. Change the
3497 doc string to indicate that this procedure isn't likely to do
3499 (scm_localtime, scm_strftime, scm_mktime): call tzset if
3500 LOCALTIME_CACHE is defined.
3502 2000-01-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3504 * posix.c (scm_sync): Return SCM_UNSPECIFIED.
3506 2000-01-09 Gary Houston <ghouston@arglist.com>
3508 * eval.c: define scm_unbound_variable_key ('unbound-variable).
3509 scm_lookupcar1: throw an error with key 'unbound-variable instead
3510 of 'misc-error when an unbound variable is encountered.
3512 * filesys.c (scm_mkdir, scm_rmdir, scm_getcwd, scm_select,
3513 scm_symlink, scm_readlink, scm_lstat),
3514 posix.c (scm_setpgid, scm_setsid, scm_ctermid, scm_tcgetpgrp,
3515 scm_tcsetpgrp, scm_uname, scm_setlocale, scm_mknod, scm_nice,
3517 simpos.c (scm_system),
3518 stime.c (scm_times, scm_strptime):
3519 move the HAVE_XXX feature tests out of the procedure bodies.
3520 don't use SCM_SYSMISSING.
3521 scm_validate.h (SCM_SYSMISSING): removed.
3522 error.h, error.c (scm_sysmissing): comment that this is deprecated.
3523 see ChangeLog entry for 1999-12-28.
3525 Sat Jan 8 19:52:04 2000 Greg J. Badros <gjb@cs.washington.edu>
3527 * scm_validate.h (SCM_VALIDATE_BOOL_COPY): Fix typo.
3529 Sat Jan 8 17:06:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3531 * backtrace.c: Fix spelling typo in a comment.
3533 * snarf.h: Use new SCM_DOCS macro to encapsulate the non SCM_INIT
3534 text. Reformatted some of the expansions.
3536 Fri Jan 7 15:50:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3538 * scm_validate.h (SCM_OUT_OF_RANGE): Use scm_out_of_range_pos to
3539 report the position of the argument.
3541 * error.h, error.c (scm_out_of_range_pos): Added this function to
3542 take extra "pos" argument, the position number of the errant
3545 * debug.c: Use SCM_OUT_OF_RANGE instead of scm_out_of_range.
3547 * snarf.h: Use SCM_HERE and SCM_INIT as names, not SCM_NOTSNARF
3548 and SCM_SNARFING. Also put the %%% in the SCM_INIT since Mikael
3549 prefers that and I'm reasonably indifferent.
3551 Fri Jan 7 15:03:32 2000 Greg J. Badros <gjb@cs.washington.edu>
3553 * snarf.h: Factor out differences between C++ and non-C++ into
3554 SCM_FUNC_CAST_ARBITRARY_ARGS macro. Modify all the snarf macro
3555 definitions to use SCM_NOTSNARF and SCM_SNARFING macros (like
3556 Mikael's macros, below, but changed names and SCM_SNARFING no
3557 longer expands to include %%% -- that must appear in the argument
3558 so that the token appears at the call-site as a reminder).
3560 2000-01-07 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3562 * snarf.h (SCM_INSITU, SCM_INIT): New snarf macros for use in user
3563 snarf macro definitions.
3565 2000-01-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3567 * chars.c (scm_integer_to_char): Use Greg's nice
3568 SCM_VALIDATE_INUM_RANGE macro for argument checking for closer
3571 Thu Jan 6 11:48:49 2000 Greg J. Badros <gjb@cs.washington.edu>
3573 * *.c, snarf.h: Replace GUILE_PROC1 with SCM_DEFINE1 throughout.
3575 Thu Jan 6 11:22:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3577 * Makefile.am (ETAGS_ARGS): Switch to SCM_DEFINE, SCM_DEFINE1
3578 instead of GUILE_PROC.
3580 Thu Jan 6 11:21:49 2000 Greg J. Badros <gjb@cs.washington.edu>
3582 * alist.c: Do not report mismatch errors on some uses of `tmp' (do
3583 this by using SCM_ARG2 instead of `2' in the SCM_VALIDATE_CONS
3586 Thu Jan 6 09:54:33 2000 Dirk Herrmann <dirk@ida.ing.tu-bs.de> --gjb applied
3588 * scm_validate.h: Remove some redundant NIMP tests.
3590 * alist.c: minimize scope of the tmp variables, and initialize
3591 them when declared. The strange SCM_NIMP tests are replaced by
3592 SCM_CONSP tests that more closely reflect the intended semantics.
3593 However, we don't get a performance penalty here, because the
3594 SCM_CONSP test was performed by the ALISTCELL test anyway. * The
3595 extremely ugly use of ASRTGO macros was removed: The calls to
3596 ASRTGO were not encapsulated by "#ifndef SCM_RECKLESS", but got a
3597 label parameter that only exists when SCM_RECKLESS is not defined.
3598 This works, because ASRTGO itself is defined in a way that it only
3599 makes use of the label parameter if SCM_RECKLESS is not defined
3600 (shudder!). Does guile make at all use of the possibility to
3601 define SCM_RECKLESS? * Codesize is likely to be reduced, since
3602 instead of two calls to SCM_ASSERT performed by the ALISTCELL test
3603 we now only get one test.
3605 * list.c: Use SCM_NNULLP, not SCM_NIMP as appropriate. Also use
3606 SCM_NULLP instead of SCM_IMP. Drop use of "register" keyword on
3607 some variables in `list?'. Fix `reverse' and `reverse!'
3608 primitives to handle improper lists better.
3610 Wed Jan 5 11:24:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3612 * *.[ch]: Whitespace changes -- added space after SCM_VALIDATE_*
3613 macros and SCM_DEFINE macros to match GNU coding standards.
3615 Wed Jan 5 11:04:24 2000 Greg J. Badros <gjb@cs.washington.edu>
3617 * *.[ch]: Replace GUILE_PROC w/ SCM_DEFINE.
3619 Wed Jan 5 10:59:06 2000 Greg J. Badros <gjb@cs.washington.edu>
3621 * *.[ch]: Replace SCM_VALIDATE_INT w/ SCM_VALIDATE_INUM for
3622 better consistency with the names of other SCM_VALIDATE_ macros
3623 and better conformance to guile naming policy.
3625 Wed Jan 5 10:50:39 2000 Greg J. Badros <gjb@cs.washington.edu>
3627 * ports.c (s_scm_close_all_ports_except): Use SCM_ARG1 in a
3628 SCM_VALIDATE instead of 1 to avoid a check on the argument (since
3629 it's not the actual name of the formal).
3631 * guile-snarf.awk.in: Do argument/number mismatch checking and
3632 print warnings in an Emacs compile-mode parseable format.
3634 * struct.c: Use SCM_ASSERT_RANGE instead of SCM_ASSERT w/
3635 SCM_OUTOFRANGE as 3rd argument.
3637 * random.c: Fix argument/number mismatch (that I introduced :-( ).
3639 * __scm.h: Do not #define SCM_ARG* when snarfing;
3640 lets us distinguish between 1 and SCM_ARG1 when snarfing as only
3641 the former (using the number) requires the argument to match the
3642 formal in the current argument snarfing check.
3644 * snarf.h: Give new definition of SCM_ASSERT when in
3645 snarfing mode to output a lexically-identifiable sequence that the
3646 guile-snarf.awk script uses to verify argument/position matching.
3648 * ramap.c: Remove extraneous #undef FUNC_NAME.
3650 Wed Jan 5 08:36:38 2000 Greg J. Badros <gjb@cs.washington.edu>
3652 * guile-doc-snarf.awk.in: Removed -- guile-snarf.awk.in is the
3653 current version of the same functionality; it writes the .x output
3654 to stdout instead of directly into the file.
3656 Wed Jan 5 08:15:04 2000 Greg J. Badros <gjb@cs.washington.edu>
3658 * unif.c, symbols.c, strings.c, stacks.c, random.c, print.c,
3659 posix.c: Eliminated a bunch of SCM_NIMP(..)s that are now
3660 redundant with the safer macros. Patch from Dirk Hermann applied
3661 by hand. Thanks Dirk!
3663 * scm_validate.h: Added SCM_VALIDATE_VECTOR_OR_DVECTOR for some
3666 * ramap.c: whitespace change.
3668 Tue Jan 4 14:21:35 2000 Greg J. Badros <gjb@cs.washington.edu>
3670 * options.c, objects.c, keywords.c, gc.c: Some redundant SCM_NIMP
3671 removals from Dirk Hermann.
3673 * alist.c: Rename formals to match the parameter names in the
3674 documentation, updates to documentation. Thanks Dirk Hermann!
3676 2000-01-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3678 * eval.c (SCM_CEVAL): Reverse order of
3679 scm_stack_checking_enabled_p and SCM_STACK_OVERFLOW_P
3680 (Thanks to Brad Knotwell.)
3682 Mon Jan 3 08:30:02 2000 Greg Harvey <Greg.Harvey@thezone.net> (applied --01/03/00 gjb)
3684 * gc.c (scm_debug_newcell): Added SCM_SETCAR of the newly
3687 * pairs.h: Added a comment about the need for the SCM_SETCAR in
3690 Mon Jan 3 08:25:19 2000 Greg J. Badros <gjb@cs.washington.edu>
3692 * dynl-vms.c, debug.c, coop-threads.c, backtrace.c, eval.c: More
3693 SCM_NIMP tests that were redundant are now eliminated. Patches
3694 from Dirk Hermann applied by hand.
