1 2000-07-23 Marius Vollmer <mvo@zagadka.ping.de>
3 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
4 scm_assoc_remove_x): Remove all cells whose key is eq, eqv, or
5 equal (respectively) to the argument key, not all cells that are
6 eq, eqv, or equal to the first cell with the argument key. Thanks
9 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
11 * gc.h (SCM_FREE_CELL_CDR, SCM_SET_FREE_CELL_CDR), hooks.c
12 (make_hook), modules.c (OBARRAY, USES, BINDER): Pack and unpack
13 SCM values appropriately.
15 * modules.c (scm_standard_eval_closure): Don't pass an inum to
16 scm_makcclo, but rather a long value.
18 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
20 read.c (scm_lreadrecparen), srcprop.c (scm_set_source_property_x):
21 SCM_SETCDR and SCM_WHASHSET macros don't deliver a return value.
22 Thanks to Han-Wen Nienhuys for the bug report.
24 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
26 * root.[ch] (scm_call_catching_errors): Deprecated.
28 * root.c (scm_init_root): Initialize the root smob type using the
29 standard initialization functions.
31 2000-07-17 Marius Vollmer <mvo@zagadka.ping.de>
33 * eval.c (unmemocopy): Don't rely on V being a list of at least
34 one element. Thanks to Bill Schottstaedt!
36 2000-07-15 Michael Livshin <mlivshin@bigfoot.com>
38 * gc.c (scm_done_free): new.
39 expanded comments about scm_done_malloc.
41 * gc.h: added prototype for scm_done_free
43 2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
45 * gc.h (scm_take_stdin): Removed.
47 * gc.h (SCM_VALIDATE_CELL): Delegate cell checks to function
48 scm_assert_cell_valid to allow extensions to the checking
49 functionality without need to recompile everything.
51 * gc.[ch] (scm_assert_cell_valid, scm_set_debug_cell_accesses_x):
52 Added as conditionally compiled functions for the case that
53 SCM_DEBUG_CELL_ACCESSES is enabled.
55 * gc.c (debug_cells_p): Added to indicate whether compile-time
56 included cell access debugging is run-time enabled.
58 * gc.[ch] (scm_gc_running_p): Added to indicate that scm_igc is
59 being executed. Intended to be used instead of scm_gc_heap_lock
62 * error.c (scm_error), gdbint.c (SCM_GC_P): Use scm_gc_running_p
63 instead of scm_gc_heap_lock.
65 * gc.c (scm_igc): Set scm_gc_running_p to true while running.
67 * gc.c (scm_mark_locations): Don't mark free cells.
69 * weaks.c (scm_scan_weak_vectors): Use SCM_FREE_CELL_P instead of
72 2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
74 * gc.c (scm_mark_locations): Minimized some variable scopes and
75 simplified the code a bit.
77 2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
79 * gc.h (SCM_SET_FREE_CELL_TYPE, SCM_SET_FREE_CELL_CDR,
80 SCM_FREE_CELL_P, SCM_FREE_CELL_CDR): Added since free cells
81 should not be accessed via SCM_C[AD]R. Further, using dedicated
82 macros to access free cells allows all other cell accessing macros
83 to treat acesses to free cells as errors, thus enabling better
84 error checks for cell accesses. SCM_FREE_CELL_P is supposed to
85 replace SCM_FREEP some time.
87 * gc.h (SCM_NEWCELL, SCM_NEWCELL2), gc.c (map_free_list,
88 free_list_length, scm_check_freelist, scm_debug_newcell,
89 scm_debug_newcell2, freelist_length, scm_gc_for_newcell,
90 scm_gc_mark, scm_gc_sweep, init_heap_seg): Only use the dedicated
91 cell accessors when accessing free cells.
93 2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
95 * gc.h (SCM_CELL_WORD, SCM_CELL_OBJECT): Treat the referenced
96 object as const in order to make the compiler warn about code like
97 SCM_CELL_WORD (x, n) = y. Instead, SCM_SET_CELL_WORD (x, n, y)
100 (SCM_CELL_WORD_LOC, SCM_CARLOC, SCM_CDRLOC): Return the address
101 as an address to a non-const object, since these macros are used
102 to allow direct write access to objects.
104 2000-07-07 Dirk Herrmann <D.Herrmann@tu-bs.de>
106 * hashtab.c (scm_hash_fn_create_handle_x): Signal an error if the
107 given hash table has no slots.
109 2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
111 * gc.c (policy_on_error): Added in order to allow alloc_some_heap
112 to react to malloc failures in a context dependent way.
114 (scm_check_freelist): No need to flush streams before abort().
116 (scm_gc_for_newcell): Try to allocate new memory in three phases:
117 grow heap if preferred, if still no memory available collect
118 garbage, if still no memory available grow heap.
120 (heap_segment_table_size): Added to always reflect the actual
121 size of the heap segment table, because scm_n_heap_segs may differ
122 from the heap segment table size.
124 (alloc_some_heap): In case of malloc failure, react according to
125 the new policy_on_error parameter (either return to caller or
126 abort immediately). Further, keep heap_segment_table_size up to
129 (scm_init_storage): Initialize heap_segment_table_size.
131 2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
133 * gh.h: Don't include <stdio.h>. Thanks to Han-Wen Nienhuys for
136 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
138 * __scm.h (SCM_OUTOFRANGE, SCM_NALLOC, SCM_HUP_SIGNAL,
139 SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL, SCM_SEGV_SIGNAL,
140 SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL, SCM_SIG_ORD,
141 SCM_ORD_SIG, SCM_NUM_SIGS): Re-introduce these as deprecated
144 * error.c (scm_wta): Re-introduce dispatching for SCM_OUTOFRANGE
145 and SCM_NALLOC, but as a deprecated feature.
147 2000-06-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
149 * debug.c: Added #include fluids.h.
151 * numbers.c (scm_gr_p, scm_leq_p, scm_geq_p): Turned into
152 primitive generics. (Thanks to Nicolas Neuss.)
154 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
156 * gc.c (alloc_some_heap): Use scm_memory_error to indicate a
157 failed attempt to get additional memory from the system.
159 (scm_gc_for_newcell): Changed the control structure to make the
160 behaviour explicit for the case that gc is not able to free any
163 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
165 * __scm.h (SCM_OUTOFRANGE): Removed.
167 * error.c (scm_wta): Removed sick dispatch code for range
168 errors. (More sick dispatches still to be removed.)
170 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
171 scm_hash_fn_remove_x): Eliminate redundant test for if unsigned
172 value is non-negative. Use scm_out_of_range to signal range
175 * hooks.c (make_hook), unif.c (scm_aind): Use scm_out_of_range to
178 * list.c (scm_list_ref, scm_list_set_x, scm_list_cdr_set_x): Fix
179 error reporting (now uses original input parameter to report wrong
180 type argument errors). Use SCM_OUT_OF_RANGE to report range
181 errors and SCM_WRONG_TYPE_ARG to report type errors.
183 * strings.c (scm_substring): Make range checks for negative
184 values explicit (former behaviour relied on an implicit
185 conversion from signed to unsigned). Don't use SCM_ASSERT for
188 * unif.c (scm_aind, scm_transpose_array, scm_bit_set_star_x,
189 scm_bit_count_star): Use scm_out_of_range to signal range
192 * unif.c (scm_transpose_array, scm_bit_position), vectors.c
193 (scm_vector_ref, scm_vector_set_x, scm_vector_move_left_x,
194 scm_vector_move_right_x): Use SCM_ASSERT_RANGE to check ranges.
196 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
198 * validate.h (SCM_VALIDATE_INUM_MIN_COPY,
199 SCM_VALIDATE_INUM_MIN_DEF_COPY, SCM_VALIDATE_INUM_RANGE_COPY):
200 Perform all range checks based on the input value. The former way
201 of using the value that is assigned to the target variable fails
202 if the assignment to the target variable itself can change the
203 value because of type conversion.
205 (SCM_ASSERT_RANGE): Use scm_out_of_range to signal range errors.
207 2000-06-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
209 * gc.c (scm_gc_for_newcell): Behave gracefully also if scm_igc
210 doesn't yield any new cells. In theory this could happen if all
211 cells allocated with NEWCELL are either in use or conservatively
212 marked and all cluster spine cells are conservatively marked.
215 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
217 * __scm.h (SCM_NALLOC): Removed.
219 * error.c (scm_wta): Removed sick dispatch code for memory
220 errors. (More sick dispatches still to be removed.)
222 * numbers.c (scm_mkbig, scm_adjbig), ports.c (scm_make_port_type),
223 random.c (scm_i_copy_rstate, scm_c_make_rstate), smob.c
224 (scm_make_smob_type), srcprop.c (scm_make_srcprops), vectors.c
225 (scm_vector_set_length_x): Now using scm_memory_error to signal
228 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
230 * __scm.h: Removed some commented code and fixed some comments.
232 (SCM_HUP_SIGNAL, SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL,
233 SCM_SEGV_SIGNAL, SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL,
234 SCM_SIG_ORD, SCM_ORD_SIG, SCM_NUM_SIGS): Removed.
236 * async.c: Removed some commented code.
238 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
240 * gc.c (scm_gc_mark, scm_gc_sweep, scm_must_malloc,
241 scm_must_realloc, scm_must_free, alloc_some_heap): Use the
242 appropriate error signalling function.
244 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
246 * root.h (scm_first_type): Removed.
248 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
250 * gc.c (MIN_GC_YIELD): Removed.
252 2000-06-28 Michael Livshin <mlivshin@bigfoot.com>
254 * gc.c (scm_gc_for_newcell): don't try to do GC if it's blocked,
257 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
259 * async.c (scm_gc_async, scm_gc_vcell, scm_sys_gc_async_thunk):
262 (scm_init_async): Moved initialization for scm_gc_async and
263 scm_gc_vcell to gc.c. Moved initialization of scm_asyncs here
266 * async.h (scm_gc_async): Not globally visible any more.
268 * gc.c (scm_gc_stats): Made callable even from within regions
271 (scm_gc_end): Eliminate the hardcoding of the marking of the
272 scm_gc_async from the gc core.
274 (scm_init_storage): Don't initialize the scm_asyncs list here.
275 This is now done in asyncs.c.
277 (scm_gc_vcell): Moved here from async.c.
279 (gc_async): Renamed from scm_gc_async, moved here from async.c
282 (gc_async_thunk): Renamed from scm_sys_gc_async_thunk and moved
285 (mark_gc_async): New hook function for scm_after_gc_c_hook.
287 (scm_init_gc): Added initialization of scm_gc_vcell and
288 gc_async. Further, add mark_gc_async to scm_after_gc_c_hook.
290 * init.c (scm_boot_guile_1): scm_init_gc requires asyncs to be
293 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
295 * gc.c (scm_igc): Removed commented code that once was intended
296 to unprotect struct types with no instances.
298 * root.h (scm_type_obj_list): Removed.
300 2000-06-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
302 * async.c (scm_init_async): Switch to standard way of smob
305 2000-06-21 Michael Livshin <mlivshin@bigfoot.com>
307 * guile-doc-snarf.in: use cut instead of sed, that's much much
308 faster. also, don't call basename more than needed. and, to gain
309 a couple of microseconds more, don't call cat needlessly. (thanks
312 2000-06-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
314 * guile-snarf.awk.in, guile-snarf.in, snarf.h: Rename SCM__I to
315 SCM_SNARF_INIT_START, SCM__D to SCM_SNARF_DOC_START, SCM__S to
316 SCM_SNARF_DOCSTRING_START and SCM__E to SCM_SNARF_DOCSTRING_END.
318 2000-06-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
320 * eval.c, eval.h (scm_top_level_lookup_closure_var): Added.
321 #include "libguile/fluids.h".
323 * eval.h (SCM_TOP_LEVEL_LOOKUP_CLOSURE): New macro which replaces
324 SCM_CDR (scm_top_level_lookup_closure_var) everywhere.
326 * root.h (scm_top_level_lookup_closure_var,
327 scm_system_transformer): Removed. (It's no sense in having the
328 *variable* be a "fluid".)
330 * root.c (mark_root): Removed marking of
331 s->top_level_lookup_closure_var and s->system_transformer.
333 * modules.c (scm_selected_module): the_module is now a fluid.
335 2000-06-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
337 * gc.h, tags.h: Be kind to compilers which must see hash signs in
338 column 0. (Thanks to Ian Grant.)
340 * numbers.h: Put #ifdef HAVE_LONG_LONGS around declarations using
341 the long_long type. (Thanks to Bernard Urban.)
343 2000-06-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
345 * gc.c, gc.h (scm_default_init_heap_size_1,
346 scm_default_min_yield_1, scm_default_init_heap_size_2,
347 scm_default_min_yield_2, scm_default_max_segment_size): New global
348 variables. Can be customized by the application before booting
349 Guile. (We might want to be able to control these parameters
350 dynamically through the "options interface" in the future, but
351 note that that is additional functionality. Here we're giving
352 default values which the environment variables can override.)
354 * list.c (scm_cons_star): Updated comment.
356 * smob.h: Changed comments for scm_make_smob_type and
357 scm_make_smob_type_mfpe, warning that the latter might be
358 deprecated in a future release.
360 2000-06-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
362 * list.[ch] (scm_cons_star/cons*): Renamed from
365 * list.[ch] (scm_list_star/list*): Provided as a deprecated alias
366 for scm_cons_star/cons*.
368 * gc.c (scm_protect_object): Updated comment.
370 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX): Removed.
372 * tags.h (SCM_UNPACK_CAR, SCM_NDOUBLE_CELLP): Removed.
374 2000-06-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
376 * init.c, init.h (scm_initialized_p): Renamed from `initialized'
379 * gdbint.c (gdb_print): Print warning instead of calling scm_write
380 if Guile isn't yet initialized.
382 * print.c (scm_current_pstate, scm_make_print_state): Simplified
383 tests, using the assumption that Guile has been initialized.
385 Sun Jun 18 14:45:21 2000 Greg J. Badros <gjb@cs.washington.edu>
387 * print.c (s_scm_current_pstate): Do not segfault when the
388 print_state_pool is unitialized in `current-pstate', and better
389 verify its state before altering it in scm_make_print_state().
391 2000-06-18 Michael Livshin <mlivshin@bigfoot.com>
393 * scmsigs.c (s_scm_sigaction): guard the SIGIOT case with an
394 #ifdef -- it's missing on at least one platform. (thanks to
397 2000-06-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
399 * list.c (list*): Added documentation from common-list.scm.
401 2000-06-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
403 * gc.c (scm_unprotect_object): The reference count is guaranteed
404 to be a positive number.
406 2000-06-15 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
408 * eval.c: Updated comment above scm_map.
410 2000-06-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
412 * gc.c (scm_protect_object): Avoid looking up the object handle
414 (scm_unprotect_object): Abort if scm_unprotect_object is called on
415 an unprotected object.
417 2000-06-14 Michael Livshin <mlivshin@bigfoot.com>
419 * gc.c (scm_unprotect_object): fix a nasty typo bug (thanks to
422 2000-06-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
424 * socket.c (scm_getsockopt): Changed type for `optlen' from int to
426 (scm_accept, scm_getsockname, scm_getpeername, scm_recvfrom):
427 Ditto for `tmp_size'.
428 (scm_addr_buffer_size): Changed type from int to size_t.
430 * random.c: #include <string.h>. (Needed by memcpy.)
432 * guile-snarf.awk.in: Replace the dot_doc_file arg with "-",
433 indicating stdin, instead of "" and don't reset ARGC. This is a
434 workaround for `nawk' in AIX 4.3 on RS6000 but, as far as I know,
435 it is correct, and perhaps even better.
437 2000-06-14 Gary Houston <ghouston@arglist.com>
439 * scmsigs.c (scm_init_scmsigs): if HAVE_SIGINTERRUPT is not
440 defined, add SA_RESTART to the sigaction flags correctly
441 (thanks to Dale P. Smith).
443 2000-06-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
445 * strings.c: #include <string.h>. (Thanks to Bill Schottstaedt.)
447 * net_db.c (scm_resolv_error): Only use macro NETDB_INTERNAL if
448 defined. It isn't on sgi irix 5.3. (Thanks to Bill Schottstaedt.)
450 * Makefile.am (.c.doc): Pipe output (the .x contents) to /dev/null.
452 2000-06-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
454 * fports.c (scm_setvbuf): Use `free' instead of `scm_must_free'
455 since read and write buffers are allocated by `malloc'.
457 * Makefile.am: Removed old test code.
459 * gh_test_c.c, gh_test_repl.c: Removed.
461 2000-06-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
463 * iselect.c (SCM_NLONGBITS): Add workaround for the Sun 4.2
466 * inet_aton.c (inet_aton): Cast init value for `cp'.
468 * ramap.c (s_scm_array_fill_x): Cast `ve' properly in case
471 * symbols.c (scm_intern_obarray_soft,
472 scm_sysintern0_no_module_lookup): Cast `name' to unsigned char ptr
473 in calls to scm_strhash.
475 * strports.c (st_resize_port): Substituted SCM_UCHARS for
477 (st_write): Cast argument to strncpy to char ptr.
478 (scm_mkstrport): Substituted SCM_ROUCHARS for SCM_ROCHARS.
479 (scm_strport_to_string): Cast argument to scm_makfromstr to char
482 * ports.c (scm_ungetc): Cast value to unsigned char ptr before
483 storing in putback_buf.
484 (scm_unread_string): Substituted SCM_ROCHARS for SCM_ROUCHARS.
486 * ioext.c (s_scm_read_line): Cast result of call to
487 scm_do_read_line to unsigned char ptr.
489 * gdbint.c (SEND_STRING): Cast argument to char pointer.
491 * fports.c (fport_flush): Declare `ptr' as unsigned char (was
494 * Makefile.am (DOT_DOC_FILES): List doc-files explicitly. (We
495 shouldn't use Make rules which aren't supported by most Make
497 (OMIT_DEPENDENCIES): Defined to "libguile.h ltdl.h". (We don't
498 want these dependencies recorded, since they would get bogus
499 relative paths; libguile.h is only used in gh.h and guile.c.)
500 (EXTRA_DOT_X_FILES, EXTRA_DOT_DOC_FILES): New variables.
501 (guile-procedures.txt): Depend on EXTRA_DOT_DOC_FILES.
502 (modinclude_HEADERS): Removed kw.h.
504 * guile-snarf.in: Change regexp "^SCM__I" --> "^ *SCM__I".
505 (The preprocessor might insert spaces before the identifier.)
507 * snarf.h (SCM_SNARF_HERE, SCM_SNARF_INIT, SCM_SNARF_DOCS):
508 Renamed from SCM_HERE, SCM_INIT, SCM_DOCS.
510 * smob.h (scm_smobfuns): Removed deprecated type.
512 * smob.c, smob.h (scm_newsmob): Removed deprecated function.
513 (Replaced by `scm_make_smob_type'.)
515 * keywords.c (scm_tc16_kw): Removed deprecated type.
516 (Replaced by scm_tc16_keyword.)
518 * kw.h: Removed deprecated header file.
520 * evalext.c (serial-map): Removed deprected alias for scm_map.
521 (Has been replaced by `map-in-order'.)
523 * ramap.c (serial-array-copy!, serial-array-map!): Removed
524 depracted aliases. (Replaced by `array-copy-in-order!' and
525 `array-map-in-order'.)
527 2000-06-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
529 * gc.h (SCM_VALIDATE_CELL): Rewritten.
530 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
531 SCM_SET_CELL_OBJECT): Use new version of SCM_VALIDATE_CELL.
532 (Thanks to Han-Wen Nienhuys.)
534 2000-06-10 Michael Livshin <mlivshin@bigfoot.com>
536 * guile-doc-snarf.in: don't pipe the CPP output right into sed --
537 write it to the temp file first and check the CPP return code.
538 (I introduced this bug earlier, and this probably caused people
539 with non-GNU C preprocessors to get empty *.x files and not to
540 have the build fail right away...).
542 * scmsigs.c (s_scm_sigaction): guard the SIGSYS case with an ifdef
543 -- at least my libc5-based Linux system doesn't define SIGSYS.
545 2000-06-08 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
547 * snarf.h, guile-snarf.awk.in, guile-snarf.in: Replaced snarf
548 markers with identifiers (SCM__I, SCM__D, SCM__S, SCM__E).
549 (Thanks to Bernard Urban.)
551 2000-06-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
553 * modules.c (scm_system_module_env_p): Fixed detection of system
556 2000-06-06 Marius Vollmer <mvo@zagadka.ping.de>
558 * scmsigs.c (scm_sigaction): Silently ignore setting handlers for
559 `program error signals' because they can't currently be handled by
562 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
564 * procs.h (SCM_SET_SUBRF): Added.
566 * procs.c (scm_make_subr_opt): Don't assign to SCM_SUBRF, use
567 SCM_SET_SUBRF instead. Thanks to Bernard Urban for the bug
570 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
572 * gc.h (SCM_CARLOC, SCM_CDRLOC): Don't take the address of a SCM
575 * sort.c (scm_sorted_p, scm_merge, scm_merge_list_x,
576 scm_merge_list_step): Don't take the address of SCM_CAR. Use
577 SCM_CARLOC instead. Thanks to Bernard Urban for the bug report.
579 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
581 * boolean.h (SCM_TRUE_P): Removed, as people might use it as a
582 replacement for !SCM_FALSEP.
584 * backtrace.c (display_error_body), boolean.h (SCM_BOOLP), gc.c
585 (scm_unhash_name), gh_data.c (gh_module_lookup), load.c
586 (scm_primitive_load), print.c (scm_simple_format), procs.c
587 (scm_procedure_documentation), procs.h (SCM_TOP_LEVEL), ramap.c
588 (scm_array_fill_int), scmsigs.c (scm_sigaction), stacks.c
589 (narrow_stack, scm_make_stack, scm_stack_id), symbols.c
590 (scm_string_to_obarray_symbol), throw.c (scm_catch,
591 scm_lazy_catch, scm_ithrow), unif.c (scm_make_uve, scm_array_p,
592 scm_array_set_x, scm_bit_set_star_x, scm_bit_count_star),
593 validate.h (SCM_VALIDATE_BOOL_COPY, SCM_VALIDATE_PROC): Replace
594 uses of SCM_TRUE_P (x) with SCM_EQ_P (x, SCM_BOOL_T).
596 2000-06-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
598 * eval.c (scm_badformalsp): New static function.
599 (SCM_CEVAL): Check arguments for procedure-with-setter closures.
600 (Thanks to Keisuke Nishida.)
602 The major reason for Guile's slow loading speed has been the fact
603 that a chain of Scheme level procedures has been evaluated for
604 every top-level symbol lookup during the first pass through the
607 The following is a kludge which I suggested four years ago, and
608 which I've repeatedly suggested since. Personally, I've never
609 been bothered by Guile's slow loading speed, so I thought I would
610 let someone else do it...
612 But since the new environments will be included first in
613 Guile-1.5, I thought it would make people happy to get the kludge
616 * modules.c: Added #include "libguile/vectors.h";
617 Added #include "libguile/hashtab.h";
618 Added #include "libguile/struct.h";
619 Added #include "libguile/variable.h";
620 Capture Scheme level `module-make-local-var!' to be used in the
621 standard eval closure.
622 (scm_standard_eval_closure): New primitive.
624 * modules.h (scm_standard_eval_closure): Declare.
626 * eval.c (scm_lookupcar): Test for !SCM_CONSP (SCM_CAR (env))
627 instead of SCM_TRUE (scm_procedurep (SCM_CAR (env))).
629 * symbols.c (scm_sym2vcell): Bypass dispatch in the evaluator for
630 standard eval closures.
632 * variable.c: Code layout fixes.
634 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
636 * Makefile.am: Added LIBS line to libpath which accidentally
637 disappeared in the change of 2000-06-01.
638 (Thanks to Dale P. Smith.)
640 2000-06-03 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
642 * scmsigs.c (scm_segfault): Removed. (Was probably added by
643 mistake since it is not mentioned in ChangeLog.)
645 * gc.h (SCM_VALIDATE_CELL): Cast result to (void) in order to
646 avoid compiler warnings in gcc. (Does this work for other
649 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
651 * gc.h (SCM_VALIDATE_CELL): Don't "use" the value returned by
653 (SCM_CARLOC, SCM_CDRLOC): Define directly instead of using
654 SCM_CELL_OBJECT_0 and SCM_CELL_OBJECT_1. It's not correct to take
655 the address of these expressions since they use SCM_VALIDATE_CELL.
656 (Thanks to Bernard Urban.)
658 * dynl.c: Changed #include <ltdl.h> --> #include
659 "libltdl/ltdl.h". (Thanks to Bill Schottstaedt.)
661 2000-06-01 Craig Brozefsky <craig@red-bean.com>
663 * Makefile.am: libguile_la_LDFLAGS gets -version-info args
664 from GUILE-VERSION definition of LIBGUILE version. Added to
665 libpath.h definitions for guileversion and libguileversion which
666 both get their values from GUILE-VERSION definition.
668 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
670 * numbers.h (SCM_BIGP): Don't use SCM_SMOB_PREDICATE in header
671 file: Code using numbers should not be required to include
674 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
676 * coop-threads.c.cygnus, coop-threads.h.cygnus, fsu-pthreads.h,
677 mit-pthreads.c, mit-pthreads.h: Deleted.
679 * Makefile.am (EXTRA_DIST), scmsigs.c, threads.[ch]: Drop
680 references to deleted files and fsu/mit thread support in
683 2000-05-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
685 * hooks.c (symbol_name, scm_create_hook): Restored the original
686 behaviour of scm_create_hook. Changing it was bad as Carl
687 R. Witty has pointed out.
689 * gc.c (scm_init_gc): We can still rely on scm_create_hook to
692 2000-05-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
694 * gc.c (scm_init_gc): Protect scm_after_gc_hook, since this will
695 soon not be done by scm_create_hook any longer.
697 * hooks.c (make_hook, print_hook, scm_create_hook,
698 scm_make_hook_with_name, scm_make_hook), hooks.h (SCM_HOOK_NAME,
699 SCM_HOOK_PROCEDURES, SCM_SET_HOOK_PROCEDURES,
700 scm_make_hook_with_name), init.c (scm_boot_guile_1): Hooks no
701 longer have names. As an intermediate solution, the name
702 predicate is emulated via object properties, but use of this
703 feature is deprecated.
705 * hooks.h (scm_free_hook): Removed, as it is never defined.
707 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
709 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_FIXABLE):
710 Un-deprecated since otherwise user code can't determine whether a
711 number fits into an inum any longer. The names should be changed
714 * numbers.c (scm_big2inum): Eliminated use of SCM_UNEGFIXABLE.
716 * tags.h (SCM_UNPACK_CAR): Deprecated.
718 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
720 * filesys.h (SCM_OPDIRP), fluids.h (SCM_FLUIDP, SCM_FLUID_NUM),
721 fports.h (SCM_OPFPORTP, SCM_OPINFPORTP, SCM_OPOUTFPORTP), hooks.h
722 (SCM_HOOK_ARITY), keywords.h (SCM_KEYWORDP, SCM_KEYWORDSYM),
723 numbers.h (SCM_NUMP, SCM_BIGSIGN, SCM_BDIGITS, SCM_NUMDIGS):
724 Replace SCM_UNPACK_CAR appropriately. Don't access cells via
725 SCM_{SET}?C[AD]R unless they are known to be cons cells.
727 * gc.c (scm_heap_seg_data_t, scm_mark_locations, scm_cellp,
728 init_heap_seg): Remove unused struct member variable 'valid'.
730 2000-05-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
732 * fports.c (fport_write), ports.c (scm_markstream, scm_port_mode,
733 scm_print_port_mode), ports.h (SCM_OPPORTP, SCM_OPINPORTP,
734 SCM_OPOUTPORTP, SCM_INPUT_PORT_P, SCM_OUTPUT_PORT_P, SCM_OPENP),
735 procs.h (SCM_CLOSCAR), unif.h (SCM_ARRAY_NDIM, SCM_ARRAY_CONTP),
736 variable.h (SCM_VARIABLEP): Replace SCM_UNPACK_CAR
739 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
741 * gc.c (free_list_length), hash.c (scm_hasher), macros.c
742 (scm_macro_type), objects.c (scm_class_of), options.c
743 (scm_options), print.c (scm_iprin1), strports.c (st_seek), throw.c
744 (SCM_LAZY_CATCH_P): Replace SCM_UNPACK_CAR appropriately.
746 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
748 * eval.c (scm_macroexp, SCM_CEVAL, scm_force), tags.h: Replace
749 SCM_UNPACK_CAR with SCM_CELL_TYPE or SCM_CELL_WORD_0.
751 * eval.c (scm_force): Add documentation.
753 * eval.c (scm_force, scm_cons_source): Don't access cells via
754 SCM_{SET}?C[AD]R unless they are known to be cons cells.
756 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
758 * strings.h (SCM_NSTRINGP, SCM_NRWSTRINGP), tags.h
759 (SCM_NDOUBLE_CELLP), vectors.h (SCM_NVECTORP): Deprecated.
761 * gc.c (scm_igc), gc.h (SCM_PTR_MASK, SCM_PTR_LT): Removed #ifdef
762 nosve #endif conditionally compiled code.
764 2000-05-23 Michael Livshin <mlivshin@bigfoot.com>
766 * gc.c (scm_heap_seg_data_t): fixed comment for the `span' member.
768 2000-05-22 Michael Livshin <mlivshin@bigfoot.com>
770 * guile-doc-snarf.in: put the preprocessed file through sed to
771 trim all lines to 1024 chars. I hope it doesn't break anybody's
772 sed. we'll see. (note: this is lossy trimming, i.e. the spill
773 isn't wrapped around but actually chopped off. this seemed to me
774 safe because the current snarfer doesn't understand multi-line
775 cookies anyway. in the long term, it would be nice not to depend
776 on AWK for anything.)
778 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): reverted
779 the previous change to this macros, after deciding to torture the
782 2000-05-21 Michael Livshin <mlivshin@bigfoot.com>
784 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): brought
785 the yucky, ugly and nasty conditional compilation back. sorry,
786 but it was either that or requiring GAWK to build Guile.
787 (lots of places): removed the code that implemented the old GC
790 * init.c (scm_boot_guile_1): removed the code conditioned on
791 !GUILE_NEW_GC_SCHEME.
793 * __scm.h: (GUILE_NEW_GC_SCHEME): removed.
795 * gc.c (scm_protect_object, scm_unprotect_object): change the
796 implementation to more efficient (at least in the time complexity
797 sense). the calls should now also be thread-safe -- I suspect
798 that people expect them to be. (thanks to Han-Wen Nienhuys)
799 (lots of places): removed the code that implemented the old GC
802 * hashtab.c (scm_hash_fn_create_handle_x): add missing
803 SCM_REALLOW_INTS before return. I really wonder about the
804 possible interactions between hashtables, threads & GC. it
805 doesn't look healthy at all.
807 2000-05-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
809 * unif.c (scm_bit_count): Fixed the parameter checks. Thanks to
812 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
814 * __scm.h (SCM_DEBUG_CELL_ACCESSES), gc.h (SCM_): Added as a new
815 debug option to verify all accesses to cells actually access
818 * gc.h (SCM_VALIDATE_CELL): Added. Only performs validation if
819 SCM_DEBUG_CELL_ACCESSES is set to 1.
821 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
822 SCM_SET_CELL_OBJECT): Use SCM_VALIDATE_CELL to check every cell
825 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
827 * gh_data.c (gh_scm2chars, gh_scm2shorts, gh_scm2longs,
828 gh_scm2floats, gh_scm2doubles): Change !SCM_NIMP to SCM_IMP.
830 * gc.c (scm_cellp): Fixed and simplified.
832 * throw.c (JBJMPBUF, SETJBJMPBUF, SCM_JBDFRAME, SCM_SETJBDFRAME,
833 make_jmpbuf, scm_init_throw): Now using double cells to represent
834 jump buffers when using debug extensions.
838 2000-05-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
840 * gh.h gh_data.c gh_funcs.c (gh_new_procedure*, gh_chars2byvect,
841 gh_shorts2svect, gh_longs2ivect, gh_ulongs2uvect, gh_floats2fvect,
842 gh_doubles2dvect, gh_doubles2scm, gh_define, gh_lookup,
843 gh_module_lookup): Accept const pointers as parameters.
845 * gh.h gh_data.c (gh_int2scmb): Deprecated.
847 2000-05-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
849 * __scm.h (SCM_DEBUG_REST_ARGUMENT): Renamed from
850 SCM_DEBUG_REST_ARGUMENTS in order to clarify that we don't test
851 the actual arguments in the list, but rather the rest argument as
854 * validate.h (SCM_VALIDATE_REST_ARGUMENT): Added.
856 * async.c (scm_noop), eval.c (scm_map, scm_for_each), list.c
857 (scm_list_star, scm_append, scm_append_x), ports.c
858 (scm_close_all_ports_except), ramap.c (scm_array_map_x,

860 (scm_make_stack), strings.c (scm_string_append), struct.c
861 (scm_make_struct, scm_make_vtable_vtable): Validate rest arguments.
863 * dynl.c (DYNL_GLOBAL, sysdep_dynl_link, kw_global, sym_global,
864 scm_dynamic_link, scm_init_dynamic_linking), dynl.h
865 (scm_dynamic_link): Removed possibility to pass flags to
866 scm_dynamic_link, as it had no effect anyway.
868 * filesys.c (scm_fcntl): Made single optional rest argument into
869 a standard optional argument.
871 * hooks.c (scm_run_hook): A list of rest arguments is never
874 * list.c (scm_append, scm_append_x), stacks.c (scm_make_stack),
875 strings.c (scm_string_append): Don't perform half-hearted checks
876 to see whether the rest argument forms a proper list any more, use
877 SCM_VALIDATE_REST_ARGUMENTS instead.
879 * ports.c (scm_close_all_ports_except): Accept empty list of rest
882 * posix.c (scm_convert_exec_args), print.c (scm_simple_format):
883 Simplify verification of rest argument.
885 * stacks.c (scm_make_stack), stacks.h (scm_make_stack), throw.c
886 (ss_handler, handler_message): Make first mandatory rest argument
887 of scm_make_stack into a standard mandatory argument.
889 * unif.c (scm_transpose_array, scm_enclose_array,
890 scm_array_in_bounds_p), unif.h (scm_transpose_array,
891 scm_enclose_array, scm_array_in_bounds_p): Make first mandatory
892 rest argument into a standard mandatory argument.
894 2000-05-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
896 * __scm.h: Added SCM_DEBUG as default debug option. (Thanks to
897 Keisuke Nishida for the suggestion.) Added debug option
898 SCM_DEBUG_REST_ARGUMENTS.
900 * eval.c (scm_map, scm_for_each): Make sure all lists have the
901 same length. Also, removed redundant parameter checks.
903 2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
905 * Makefile.am: Let 'make clean' remove *.x and *.doc files.
907 * __scm.h: Improved explanation of giving options to make.
909 * __scm.h (SCM_DEBUG_TYPING_STRICTNESS), tags.h
910 (SCM_STRICT_TYPING, SCM_DEBUG_TYPING_STRICTNESS): Renamed
911 SCM_STRICT_TYPING to SCM_DEBUG_TYPING_STRICTNESS and moved the
912 corresponding declaration and comment to __scm.h.

915 (scm_remainder, scm_modulo), numbers.h (SCM_SRS, SCM_MAKINUM,
916 SCM_INUM): Removed conditionally compiled code for Turbo C.
918 * gdbint.c (gdb_maybe_valid_type_p): Eliminated call to scm_tag.
919 That check can be assumed to be redundant except for very rare
920 conditions that actually indicate broken heap data.
922 2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
924 * numbers.c (scm_logcount, scm_integer_length): Reordered
927 2000-05-15 Gary Houston <ghouston@arglist.com>
929 * stime.c (scm_strftime): don't reset TZ if zone is an empty
930 string. append a "0" to the zone for TZ.
932 2000-05-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
934 * numbers.c (scm_logbit_p, scm_bit_extract): Reordered dispatch
937 (scm_bit_extract): Fixed handling of bignums.

949 (scm_tc16_flo, scm_tc_flo, scm_tc_dblr, scm_tc_dblc): Wrapped
950 deprecated code between #if (SCM_DEBUG_DEPRECATED == 0) #endif.
952 * fports.c (scm_fport_buffer_add), ports.c (scm_input_port_p,
953 scm_output_port_p), print.c (scm_get_print_state), validate.h
954 (SCM_VALIDATE_CHAR): Replace use of deprecated macros
955 SCM_INPORTP, SCM_OUTPORTP, SCM_ICHRP by SCM_INPUT_PORT_P,
956 SCM_OUTPUT_PORT_P, SCM_CHARP, respectively.
958 2000-05-14 Gary Houston <ghouston@arglist.com>
960 * stime.c (scm_strftime): if HAVE_TM_ZONE is not defined, hack the
961 TZ environment variable so that the %Z format returns the zone
962 from the input vector instead of the system default.
964 from Keisuke Nishida:
965 * fports.c (scm_setvbuf): minor docstring fix.
966 * ports.h (scm_generic_fgets): obsolete prototype deleted.
968 2000-05-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
970 * __scm.h: Added new section for debugging options.
972 (SCM_DEBUG_DEPRECATED): If 1, no deprecated code is included to
973 help developers to get rid of references to deprecated code.
975 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_UNEGFIXABLE,
976 SCM_FIXABLE, SCM_FLOBUFLEN): These macros are no longer provided
977 as part of the interface and are marked as deprecated in the
980 * numbers.c (scm_make_real, scm_make_complex): Inlined the
981 corresponding macros SCM_NEWREAL and SCM_NEWCOMPLEX,
984 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX, SCM_INEXP, SCM_CPLXP,
985 SCM_REAL, SCM_IMAG, SCM_REALPART, scm_makdbl, SCM_SINGP,

990 * gc.h (scm_cell, SCM_CELL_WORD, SCM_CELL_OBJECT,
991 SCM_SET_CELL_WORD, SCM_SET_CELL_OBJECT): Scheme cells now consist
992 of two scm_bits_t values instead of two SCM values, because it is
993 legal for cell entries to hold values that are not scheme objects.
995 (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR):
996 Use SCM_SETC[AD]R to modify contents of pairs.

1000 * numbers.c (IS_INF, isfinite): Added FIXME comment.
1002 (scm_abs, scm_magnitude): Make these two independent of each
1003 other. scm_abs now reports an error if given a complex argument.
1005 (scm_istr2flo, scm_integer_p). Use SCM_REAL_VALUE instead of
1006 SCM_REALPART if the object is known to be real.
1008 (scm_init_numbers): No need to use SCM_NEWREAL macro for speed
1011 * numbers.h (SCM_SINGP): Set to 0 instead of SCM_BOOL_F.
1013 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>

1021 vector_sum_squares), unif.c (scm_make_uve, scm_array_p,
1022 scm_array_set_x): Use SCM_REAL_VALUE instead of SCM_REALPART if
1023 the object is known to be real. Use SCM_COMPLEXP instead of
1024 deprecated SCM_CPLXP. Use SCM_INEXACTP instead of deprecated
1027 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1029 * numbers.c: No need to include unif.h.
1031 (IS_INF): Returned to old test for now: x == x + 1 will not work
1032 for large numbers due to rounding errors.
1033 Thanks to Kalle Olavi Niemitalo.
1035 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
1037 * numbers.c (scm_divbigdig): Removed outdated comment.

1040 scm_real_p, scm_integer_p, scm_inexact_p, scm_gr_p, scm_leq_p,
1041 scm_geq_p, scm_make_rectangular, scm_make_polar,
1042 scm_inexact_to_exact): Added comments.
1044 (add1, scm_init_numbers): Removed add1.
1046 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
1048 * numbers.c (IS_INF): The new test is x == x + 1. The old test
1049 x == x/2 did not work for zero values. Thanks to Han-Wen Nienhuys
1052 (scm_number_to_string, scm_sum, scm_difference, scm_two_doubles,
1053 scm_num2long, scm_num2long_long, scm_num2ulong): Reordered
1056 2000-05-09 Marius Vollmer <mvo@zagadka.ping.de>
1058 * scmsigs.c (take_signal): Execute SCM_ASYNC_TICK for SIGSEGV,
1059 SIGILL and SIGBUS signals. These signals are not continuable and
1060 must be handled for real right away.
1062 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1064 * numbers.c (scm_zero_p, scm_positive_p, scm_negative_p,
1065 scm_real_part, scm_imag_part, scm_magnitude,
1066 scm_inexact_to_exact): Reordered dispatch sequence.
1068 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1070 * feature.c: No need to include "libguile/smob.h"
1072 (scm_loc_features, features, scm_add_feature, scm_init_feature):
1073 Removed variable 'scm_loc_features' as a pointer to the SCM value
1074 holding the features list. Using variable 'features' instead,
1075 which holds the interned pair. Thus, SCM_SETCDR can be used
1076 instead of pointer trickery.
1078 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1080 * alist.c (scm_acons): Use SCM{_SET}?_CELL_OBJECT as long as a
1081 cell is not known to be a valid pair.
1083 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1085 * eval.c (ASRTSYNTAX, scm_m_body, scm_m_letrec1): Removed

1092 (bodycheck): Removed.
1094 * stacks.c (stack_depth, read_frame, read_frames): Removed
1095 redundant calculation of size, minimized some variable scopes.
1097 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1099 * pairs.c (scm_cons, scm_cons2): Use SCM{_SET}?_CELL_OBJECT as
1100 long as a cell is not known to be a valid pair.
1102 (scm_pair_p): Eliminated redundant SCM_IMP test.
1104 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1106 * eval.c (scm_m_body, scm_macroexp, unmemocopy, scm_eval_args,
1107 scm_deval_args): Eliminated redundant SCM_IMP tests.
1109 * hashtab.c (scm_ihashx, scm_sloppy_assx, scm_delx_x), weaks.c
1110 (scm_make_weak_key_hash_table, scm_make_weak_value_hash_table,
1111 scm_make_doubly_weak_hash_table): Fixed critical sections.
1112 Thanks to Keisuke Nishida.
1114 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1116 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest):
1117 Fixed some goto-related initialization bugs (introduced by me).
1119 2000-05-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
1121 * numbers.h (SCM_INUM0): Uses SCM_MAKINUM instead of SCM_PACK.
1123 * dynl.c (dynl_obj, DYNL_OBJ, get_dynl_obj): Removed.
1125 (DYNL_FILENAME, DYNL_HANDLE): Use SCM_CELL... macros instead of
1128 (SET_DYNL_HANDLE): Added.
1130 (scm_dynamic_object_p): Simplified.
1132 (scm_dynamic_unlink, scm_dynamic_func): Changed comment. Deliver
1133 better error message when accessing unlinked dynamic objects.
1134 Eliminated call to get_dynl_obj.
1136 2000-05-03 Marius Vollmer <mvo@zagadka.ping.de>
1138 * scmsigs.c (orig_handlers) [!HAVE_SIGACTION]: Fix declaration to
1139 be an array of function pointers instead of being a pointer to an
1140 array returning function. Thanks to Kalle Olavi Niemitalo!
1142 2000-05-03 Dirk Herrmann <D.Herrmann@tu-bs.de>
1144 * numbers.c (scm_divbigbig, scm_divbigint), numbers.h
1145 (scm_divbigbig, scm_divbigint): Don't return zero any more to
1146 indicate that a division has a remainder, return SCM_UNDEFINED
1147 instead. It is improbable that anyone actually used these
1148 functions outside of numbers.c. For this reason and due to the
1149 change in behaviour the functions are static now. Thus, if
1150 surprisingly there are users of these functions they will at least
1153 * numbers.c: Removed #ifdef SCM_BIGDIG #endif in those functions,
1154 that already have a clean dispatch order. Note: SCM_BIGDIG is
1157 * numbers.c (scm_inexact_p): Simplified.
1159 * numbers.c (scm_num_eq_p, scm_less_p, scm_max, scm_min,
1160 scm_product, scm_num2dbl, scm_angle): Reordered dispatch
1161 sequence, thereby fixing some comparisons of SCM values with
1164 * numbers.c (scm_divide): Division by zero of inums leads to an
1165 error now. (Formerly, an infinite number was returned.)
1167 Respect the fact, that scm_divbigbig does now return SCM_UNDEFINED
1168 if a division has a remainder.
1170 2000-05-02 Gary Houston <ghouston@arglist.com>
1172 * Makefile.am (INCLUDES): add ${INCLTDL} (thanks to Tim Mooney).
1174 2000-05-02 Dirk Herrmann <D.Herrmann@tu-bs.de>
1176 * numbers.c (scm_logtest, scm_division): Reordered dispatch

1192 call to scm_makdbl with a call to scm_make_real or
1193 scm_make_complex, depending on whether the imaginary part is known

1198 * scmsigs.c: fix the definition of orig_handlers for the case
1199 that HAVE_SIGACTION is not defined (thanks to
1200 Kalle Olavi Niemitalo).
1202 * Makefile.am: remove include_HEADERS (was libguile.h)
1203 libguile.h: moved to top level directory.
1205 2000-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1207 * numbers.c (SCM_SWAP): Moved to the top of the file to allow for
1210 * numbers.c (scm_modulo, scm_gcd, scm_lcm, scm_logand, scm_logior,

1243 * procs.c (scm_init_iprocs), procs.h (scm_subr, scm_iproc,
1244 scm_dsubr, scm_init_iprocs): Removed.
1246 * procs.h (SCM_SUBRF, SCM_DSUBRF): Access the cell words
1247 directly instead of casting a cell to a C struct.
1249 2000-04-22 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1251 Better modularization of GC extensions through new C level GC

1309 the root build directory.
1311 * numbers.c (scm_odd_p, scm_even_p): Use SCM_WRONG_TYPE_ARG
1312 instead of SCM_ASSERT (0, ...). (Some compilers will complain

1333 scm_quotient): Reordered dispatch sequence to first handle
1334 immediates, second handle bignums and finally handle generic
1335 functions respectively signal wrong type arguments. Hopefully
1336 this will allow for easier separation when goops is integrated.
1338 2000-04-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
1340 * gc.c (which_seg): Use SCM2PTR to convert a non immediate SCM

1592 * coop.c (mother): Handled EINTR (the wait has been interrupted by
1595 2000-04-07 Dirk Herrmann <D.Herrmann@tu-bs.de>
1597 * __scm.h (SCM_WTA_DISPATCH_[012n]): To test whether a SCM value
1598 contains a raw zero value it has to be unpacked.
1600 * debug.c (with_traps_inner, scm_with_traps): Passing SCM values
1601 via void * requires unpacking / packing.
1603 * stacks.h (SCM_STACKP): Remove unnecessary SCM_NIMP test and use
1604 SCM_EQ_P to compare SCM values.
1606 * stacks.h (SCM_FRAME_VOID_P, SCM_FRAME_REAL_P, SCM_FRAME_PROC_P,

1615 2000-04-05 Michael Livshin <mlivshin@bigfoot.com>
1617 * async.[ch]: unexpose low-level async access macros (thanks to
1620 * validate.h: move async validation macros to async.c (nobody else
1621 needs them anyway), and rename them.
1623 2000-04-04 Michael Livshin <mlivshin@bigfoot.com>
1625 * async.h: kill the scm_async_t struct. having a heap cell
1626 pretending to be a C struct is not helthy, and is not needed here
1627 anyway, as asyncs happily fit in one heap cell.
1629 * async.c: reflect the fact that asyncs are now represented by
1630 single heap cell each.
1632 2000-04-04 Gary Houston <ghouston@arglist.com>
1634 * error.c (scm_syserror): save errno before doing anything else,

1692 (Thanks to Tim Mooney.)
1694 2000-04-03 Michael Livshin <mlivshin@bigfoot.com>
1696 * guardians.c (scm_guardian_zombify): mark all zombies in a
1697 separate loop after processing all the currently known live
1698 guardians, so as to not introduce order dependencies (thanks to
1699 Gary Houston). note that the order problems are still there if
1700 some guardians are themselves zombies, but that's a sick case that
1701 I'm not going to worry about.
1702 also, make another outer loop to process zombified
1703 guardians (which are uncovered while marking zombies).

1793 use of an improper list (which breaks g_print. g_print isn't
1795 guardians.c: Added more comments and modified the make-guardian

1849 coop_mother, coop_child): New variables.
1850 (mother): New function.
1851 (coop_create): New thread spawning mechanism which uses a "mother
1852 thread". The "dummy" pthreads aren't healthy enough to give birth
1853 to new threads since Linux threads thinks they are asleep.
1855 * coop-defs.h (struct coop_t): Removed dummy_mutex.
1857 * coop-defs.h, coop-threads.c (struct coop_t): Eliminate
1858 `sto'-field when GUILE_PTHREAD_COMPAT is enabled.

1919 2000-03-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1921 * threads.c (scm_init_threads): Pass 0 size to scm_make_smob_type
1922 for scm_tc16_thread. As the current COOP threads are written, GC
1923 is not supposed to manage storage for threads.
1925 * error.c (scm_error): Don't try to throw an error if
1926 scm_gc_heap_lock is true.

1969 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
1971 * gc.h (SCM_NEWCELL, SCM_NEWCELL2): Use SCM_SET_CELL_TYPE to set
1972 the type entry of a new cell. Added a comment about things to
1973 remember when updating the list of free cells.
1975 (SCM_FREEP, SCM_MARKEDP): Use SCM_CELL_TYPE to access the type
1978 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
1980 * pairs.h (SCM_CAR, SCM_CDR, SCM_SETCAR, SCM_SETCDR): Use
1981 SCM_CELL_OBJECT and SCM_SET_CELL_OBJECT. This change implies that
1982 with strict type checking enabled these macros will only work if
1983 given valid SCM parameters.
1985 (SCM_GCCDR): Moved to tags.h.
1987 * tags.h (SCM_GCCDR): Moved here from pairs.h.
1989 2000-03-26 Dirk Herrmann <D.Herrmann@tu-bs.de>

1999 (SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR, SCM_SETAND_CDR,
2000 SCM_SETOR_CAR, SCM_SETOR_CDR): Moved to gc.h. These names should
2001 be changed, though, since the macros are not only pair related.
2005 * gc.h (SCM2PTR, PTR2SCM, scm_cell, SCM_CELLPTR, SCM_CELL_WORD*,

2015 * tags.h (SCM_STRICT_TYPING): New macro that, if defined,
2016 activates strict compile time type checking for variables of
2018 (SCM, SCM_PACK, SCM_UNPACK): Define according to whether
2019 SCM_STRICT_TYPING or SCM_VOIDP_TEST are defined.
2020 (SCM_EQ_P): Defined as a macro equivalent for eq?.
2022 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2024 * tags.h (SCM_POINTERS_MUNGED): Removed.
2026 * gc.c (scm_gc_sweep, init_heap_seg): Removed use of
2027 SCM_POINTERS_MUNGED, thus fixing some illegal casts to SCM.

2031 * pairs.h (SCM_CELL_OBJECT, SCM_CELL_OBJECT_[0-3],
2032 SCM_SET_CELL_OBJECT, SCM_SET_CELL_OBJECT_[0-3], SCM_CELL_TYPE,
2033 SCM_SET_CELL_TYPE): Added a set of low level macros for accessing
2035 (SCM_CELL_WORD_[0-3]): Renamed from the SCM_CELL_WORD[0-3].
2037 * procs.h, procs.c: Instead of SCM_{SET_}?CELL_WORD[12], use the
2038 newly introduced SCM_{SET_}?CELL_OBJECT_[12] macros.
2040 2000-03-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2042 * tags.h: Disabled definition of SCM_VOIDP_TEST.
2044 Defining SCM as void * introduces problems which haven't been
2045 handled yet. Developers who work with these issues can enable it
2046 in their working copies.
2048 Disabling this definition exposes a set of newly introduced and
2049 older misuses of types which causes warning messages during
2050 compilation. We'll fix this successively.
2052 * gc.c (scm_mark_locations): Changed * (SCM **) X --> * (SCM *) X
2053 in order to obtain a value of type SCM.
2054 (scm_cellp): Updated with new changes to scm_mark_locations.
2056 * continuations.h (SCM_SETJMPBUF): Cast second arg into SCM.
2058 * continuations.c (scm_make_cont): Removed cast of size_t into
2061 * symbols.h (SCM_SETCHARS): Cast second arg into SCM.
2063 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
2065 * numbers.h (SCM_SETNUMDIGS): Use SCM_BIGSIZEFIELD macro for
2066 shifting, not constant. Thanks to Dale P. Smith.
2068 * numbers.c (scm_sum, scm_difference): Don't test a SCM value
2069 for being less than zero. Decode it to a C value first. Again,
2072 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
2074 * numbers.h, ramap.c, struct.h, vectors.h: Don't use SCM2PTR for
2075 non scheme values. If raw data is stored in SCM variables, it has
2076 to be accessed using SCM_UNPACK until a better solution is found.
2078 2000-03-22 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2080 * tags.h (SCM_ECONSP, SCM_NECONSP): More corrections of
2081 pointer-arithmetic induced by the SCM_PACK/UNPACK change.
2083 * print.c (scm_iprin1): SCM_PACK/UNPACK corrections.
2085 * gc.c (scm_gc_sweep): SCM_PACK/UNPACK corrections.
2087 * eval.c (SCM_CEVAL, scm_unmemocar): SCM_PACK/UNPACK corrections.
2089 * dynwind.c (scm_swap_bindings): SCM_PACK/UNPACK corrections.
2091 * async.c, __scm.h: Removed lots of the old async click logic. It
2092 is possible to reinsert it by defining GUILE_OLD_ASYNC_CLICK in
2093 __scm.h. Let's try this out and dump the old code after the
2094 threads reorganization.
2095 (set-tick-rate, set-switch-rate): Conditionally removed.
2097 2000-03-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2099 * gc.c (scm_gc_mark): Bugfix 1: The recent SCM_PACK/UNPACK change
2100 made SCM values into pointers. This turned an arithmetic
2101 computation of the address of the vcell into a pointer-arithmetic
2102 one, thereby screwing up marking of structs.
2103 Bugfix 2: Removed incompletely introduced loop variable `j' used
2104 when protecting the tail array of a struct.
2106 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2108 * struct.h (SCM_STRUCT_DATA): Don't cast SCM values to pointers.
2110 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2112 * symbols.h, symbols.c (scm_strhash): Declare the string
2113 parameter as constant, since it is not modified.
2115 * symbols.c (scm_intern_obarray_soft,
2116 scm_sysintern0_no_module_lookup): Can now pass constant strings
2117 to scm_strhash without need for casting.
2119 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2121 * vectors.h (SCM_VELTS, SCM_VELTS_AS_STACKITEMS): Don't cast SCM
2122 values to pointers. Use SCM2PTR instead.
2124 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2126 * async.c (scm_set_tick_rate, scm_set_switch_rate): Don't unpack
2127 results of SCM_INUM.
2129 2000-03-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2131 * init.c (scm_boot_guile_1): Renamed GUILE_GC_TRIGGER_1 -->
2132 GUILE_MIN_YIELD_1, GUILE_GC_TRIGGER_2 --> GUILE_MIN_YIELD_2.
2133 GUILE_MIN_YIELD_X now take *positive* fractions of heap size.
2135 * gc.c, gc.h (SCM_MIN_YIELD_1, SCM_MIN_YIELD_2,
2136 min_yield_fraction, min_yield, adjust_min_yield): Renamed from
2137 SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2, gc_trigger_fraction,
2138 gc_trigger, adjust_gc_trigger.
2140 * gc.c (alloc_some_heap): Further improvement of minimal heap size
2142 (SCM_MAX): New macro.
2143 (scm_freelist_t): New field: collected_1. Previous amount of
2145 (gc_sweep_freelist_finish): Trigger based on two last values of
2146 freelist->collected to avoid unnecessary allocation due to
2148 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2):
2149 Adjusted to 45000 cells, 40% and 40%. Gives quick startup
2150 without extra heap allocation.
2152 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2154 * numbers.h (SCM_MAKINUM): The parameter to SCM_MAKINUM should
2155 already be a C value. No need to unpack it.
2157 * numbers.c (scm_long_long2num): Cast the parameter to scm_bits_t
2158 if we know it fits into an inum.
2160 * ramap.c (ramap_rp): An scm_tc7_[ui]vect object does point to a
2161 field of long values. In contrast, SCM_VELTS accesses a field of
2164 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2166 * gc.c (scm_gc_stats): Inserted explanation of local_scm_mtrigger
2168 (scm_gc_yield_1): New variable: Holds previous yield. Used to
2169 make better judgements.
2170 (gc_sweep_freelist_finish): Inserted explanation of use of
2173 * print.h, stacks.h, options.c, options.h: Changed C++
2176 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2178 * tags.h (SCM2PTR, PTR2SCM): Use SCM_PACK / SCM_UNPACK correctly.
2180 * numbers.h (SCM_INUMP, SCM_MAKINUM, SCM_INUM0, SCM_COMPLEX_REAL,
2181 SCM_COMPLEX_IMAG, SCM_NUMP, SCM_BDIGITS): Use SCM_PACK /
2182 SCM_UNPACK / SCM2PTR correctly.
2184 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2186 * gc.c (adjust_gc_trigger): Improved documentation.
2187 (alloc_some_heap): Since gc_trigger is used against
2188 freelist->collected, this is the value which should be used to
2189 predict minimum growth.
2191 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2193 * eval.h: Fix mixup of packed/unpacked SCM values. (Thanks
2194 Thien-Thi Nguyen for the patch.)
2196 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2198 * numbers.c (scm_ash): Fixed typing problems with the second
2199 parameter and added some documentation. (Thanks Thien-Thi Nguyen
2200 for indicating the problem.)
2202 2000-03-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2204 * gc.c, gc.h (scm_gc_yield): New variable.
2205 (adjust_gc_trigger): Use scm_gc_yield.
2206 (alloc_some_heap): Use scm_gc_yield instead of
2207 scm_gc_cells_collected.
2209 * coop-threads.c: Addd #include "root.h", #include "strings.h".
2211 * debug.c: Added #include "root.h". (Thanks to Thien-Thi Nguyen.)
2213 * gc.c (scm_gc_for_newcell, adjust_gc_trigger): Improved GC
2214 trigger adjustmeant: Take yield (freed cells) for all freelists
2216 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Tuned
2217 to 50000 cell heap with 45% trigger.
2218 (scm_gc_cells_collected): Reintroduced.
2219 (SCM_HEAP_SIZE): New macro.
2220 (scm_gc_sweep): Reintroduced correct computation of
2221 scm_cells_allocated.
2222 (scm_freelist_t): Corrected commentary for field `cluster_size':
2223 Clustersize counts objects, not cells; New member
2224 `clusters_allocated'.
2226 2000-03-19 Michael Livshin <mlivshin@bigfoot.com>
2228 * *.[hc]: add Emacs magic at the end of file, to ensure GNU
2231 2000-03-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2233 * threads.h: Added #include "libguile/throw.h". (Thanks to
2236 2000-03-18 Michael Livshin <mlivshin@bigfoot.com>
2238 * tags.h: (SCM_DOUBLE_CELLP, SCM_NDOUBLE_CELLP): new macros (bad
2239 names, anyone got any better ones?)
2241 * gc.h: (typedef struct scm_freelist_t) remove from here.
2243 * gc.c: (CELL_UP, CELL_DN) made these macros take additional
2244 parameter (the span).
2245 (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK) new macros.
2246 (typedef struct scm_freelist_t) moved here from gc.h, it had no
2247 business being externally visible.
2248 (typedef struct scm_heap_seg_data_t) renamed from
2249 scm_heap_seg_data, to be style-compliant.
2250 (scm_mark_locations) if the possible pointer points to a
2251 double-cell, check that it's properly aligned.
2252 (init_heap_seg) align double-cells properly, work with the
2253 assumption that the segment size divides cleanly by cluster size.
2254 (round_to_cluster_size) new function.
2255 (alloc_some_heap, make_initial_segment) use round_to_cluster_size
2256 to satisfy the new init_heap_seg invariant.
2258 2000-03-18 Dirk Herrmann <D.Herrmann@tu-bs.de>

2315 2000-03-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2317 * gc.c, gc.h: Cleanup of the change of 2000-03-15.
2318 Cluster sizes are now independent of GC trigger values.
2319 GUILE_GC_TRIGGER_n can now specify a relative trigger value:
2320 A negative integer gives fraction of total heap size in percent.
2321 (SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Default values set to -40.
2323 * init.c (scm_boot_guile_1): Introduced new variable
2324 GUILE_MAX_SEGMENT_SIZE; New environment variable names:
2325 GUILE_INIT_SEGMENT_SIZE_1, GUILE_GC_TRIGGER_1,
2326 GUILE_INIT_SEGMENT_SIZE_2, GUILE_GC_TRIGGER_2
2328 2000-03-16 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2330 * __scm.h (GC_FREE_SEGMENTS): Disable this until we have made
2331 freeing of segment work with the new GC scheme. (Thanks to
2332 Michael Livshin.) Oops, also happened to make GUILE_NEW_GC_SCHEME
2333 the default, but I'll let this change stay in CVS Guile since this
2334 code is not expected to contain serious bugs.
2336 2000-03-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2338 * gc.c, gc.h (scm_map_free_list): Define also if GUILE_DEBUG is
2340 (scm_free_list_length): New procedure (GUILE_DEBUG).
2341 Fixed a small but serious bug introduced by the previous change.
2343 * gc.c (scm_gc_sweep): Moved variable n_objects to inner sweep
2344 loop and declare as register.
2346 * gc.c (scm_gc_sweep): Sigh... forgot to clear private freelists
2349 Wed Mar 15 08:27:04 2000 Greg J. Badros <gjb@cs.washington.edu>
2351 * fluids.c: Docstring patch from Keisuke Nishida. Some
2352 reindentation, too, and a couple formals renamed. Should
2353 fluid-set! return UNSPECIFIED instead of a value?
2355 Wed Mar 15 08:24:58 2000 Greg J. Badros <gjb@cs.washington.edu>
2357 * Makefile.am: Separate out DOT_X_FILES and DOT_DOC_FILES, and
2358 generate the latter from the concrete listing of the former. Then
2359 make guile-procedures.txt depend on DOT_DOC_FILES instead of
2360 *.doc, so that rebuilding it works.
2362 Wed Mar 15 08:12:14 2000 Greg J. Badros <gjb@cs.washington.edu>
2364 * libguile.h: Include libguile/validate.h. Thanks Keisuke Nishida!
2366 * guile-snarf.awk.in: Replace docstring line-ending \n" and \n\n"
2367 with nothing and \n, respectively. Thanks Keisuke Nishida for
2368 noticing this problem.
2370 2000-03-15 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2372 * __scm.h (GUILE_NEW_GC_SCHEME): Define this if you want to test a
2373 new way of allocating heap. It makes Guile fast, but still
2376 * gc.c, gc.h, pairs.h, init.c: Implementation of a new way of
2377 allocating heap. The basic idea is to trigger GC every Nth
2378 allocated cell and grow heap when free list runs out. The scheme
2379 has been extended so that GC isn't triggered until all remaining
2380 cells are used. The implementation is also prepared for
2381 development in the direction of POSIX threads.
2383 * gc.c (SCM_EXPHEAP): In order to grow by a factor of 1.5,
2384 SCM_EXPHEAP should return half of the heap size.
2386 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2388 The following change to init.c is only enabled if Guile was
2389 configured with --enable-guile-debug.
2391 * init.c (scm_i_getenv_int): New function.
2392 (scm_boot_guile_1): Use the environment variables
2393 GUILE_INIT_HEAP_SIZE, GUILE_INIT_HEAP_SIZE2 to select heap size if
2394 they exist. (This may be replaced by a Scheme level mechanism in
2397 * objprop.c (s_scm_set_object_property_x): Use scm_assq instead of
2398 scm_assoc. (Thanks to Keisuke Nishida.)
2400 2000-03-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2402 * eval.c, lang.c, lang.h (scm_lisp_nil, scm_lisp_t): Renamed from
2403 scm_nil, scm_t. (Thanks to Keisuke Nishida.)
2405 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2407 * init.c (scm_boot_guile_1): Use same initial segment size for
2408 1-word and 2-word segments. Having the smaller size causes Guile
2409 to GC too often. Obviously something needs to be done to allow
2410 for a smaller 2-word segment without this to happen. (The amount
2411 of heap for each type should be automatically adapted to the
2412 application somehow.)
2414 [Almost all of these changes should be documented in the NEWS
2417 * gc.h (scm_freelist_t): New type.
2419 * pairs.h (SCM_NEWCELL, SCM_NEWCELL2): Use new style freelists.
2421 * gc.c (SCM_INIT_HEAP_SIZE): Changed from 32768 --> 40000 so that
2422 all of Guile basics fits into one segment and there suitable room
2424 (SCM_EXPHEAP): Now takes an argument. Grow by a factor of 1.5
2426 (scm_freelist, scm_freelist2): Now of type scm_freelist_t.
2427 Freelists now contains information about object span, cells
2428 collected and amount of cells in heap segments belonging to the
2430 (scm_heap_size, scm_gc_cells_collected): Removed.
2432 * init.c (scm_boot_guile_1): Make 2-word segment 8K (512 cells).
2434 * Makefile.am (libguile_la_LDFLAGS): Bumped library version
2437 * __scm.h eq.c, eval.c, gc.c, gc.h, gh_data, hash.c, numbers.c,
2438 numbers.h, objects.c, ramap.c, random.c, unif.c, unif.h: Extensive
2439 rewrite of handling of real and complex numbers.
2440 (SCM_FLOATS, SCM_SINGLES): These #ifdef conditionals have been
2441 removed along with the support for floats. (Float vectors are
2444 * tags.h (scm_tcs_bignums): Removed.
2445 (scm_tc16_bigpos, scm_tc16_bigneg): Replaced by scm_tc16_big.
2446 Use SCM_BIGSIGN(x) to test for sign!
2447 (scm_tc16_big): The new bignum type.
2448 (SCM_REAL_PART, SCM_IMAG_PART): Removed.
2450 * numbers.h (SCM_BIGSIGN): Sign moved to bit 16.
2451 (scm_makdbl): Deprecated.
2452 (SCM_NEWREAL, SCM_NEWCOMPLEX): New macros.
2453 (SCM_SINGP): Deprecated.
2455 (SCM_INEXP, SCM_CPLXP): Deprecated.
2456 (SCM_INEXACTP, SCM_COMPLEXP): New macros.
2457 (SCM_COMPLEX_REAL, SCM_COMPLEX_IMAG): Renamed from
2458 SCM_REAL, SCM_IMAG (and now only valid for complex numbers).
2459 (SCM_REAL, SCM_IMAG): New, *deprecated*, selectors which work both
2460 for doubles and complex numbers.
2461 (SCM_REAL_VALUE): New selector for doubles.
2462 (scm_double_t, scm_complex_t): New types.
2465 * numbers.c (scm_floprint, scm_floequal): Removed.
2466 (scm_print_real, scm_print_complex, scm_real_equalp,
2467 scm_complex_equalp): New functions.
2469 * unif.c (scm_makflo): Removed.
2471 * smob.h (SCM_SMOB_PREDICATE): New macro.
2472 (SCM_NEWSMOB2, SCM_RETURN_NEWSMOB2, SCM_NEWSMOB3,
2473 SCM_RETURN_NEWSMOB3): New macros.
2475 1999-11-21 Michael Livshin <mlivshin@bigfoot.com>
2477 The following changes implement primitive support for double cells
2478 (i.e. four-word cells) and change the representation of some
2479 things to multi-cells instead of cons+malloc. (Applied and
2482 * pairs.h (SCM_NEWCELL2): double-cell variants of SCM_NEWCELL.
2483 (SCM_CELL_WORD, SCM_CELL_WORDLOC, SCM_SET_CELL_WORD): primitive
2484 multi-cell access macros (used by the ones below).
2485 (SCM_CELL_WORD[0-3], SCM_SET_CELL_WORD[0-3]): multi-cell access
2488 * gc.c (scm_freelist2): multi-cell freelists.
2489 (inner_map_free_list): map_free_list, parameterized on ncells.
2490 "nn cells in segment mm" was misleading for ncells > 1; changed to
2491 "objects". still print cells too, though.
2492 (scm_map_free_list): rewritten using inner_map_free_list.
2493 (scm_check_freelist): get freelist as parameter, since now we have
2495 (scm_debug_newcell2): multi-cell variants of
2497 (scm_gc_for_newcell): take ncells and freelist pointer as
2499 (scm_gc_mark): add case for tc7_pws (procedures with setters are
2501 (scm_gc_sweep): don't free the float data, since it's not malloced
2503 (init_heap_seg): didn't understand what n_new_objects stood for,
2504 so changed to n_new_cells.
2505 (make_initial_segment): new function, makes an initial segment
2506 according to given ncells.
2507 (scm_init_storage): call make_initial_segment, for ncells={1,2,3}.
2509 * numbers.c (scm_makdbl): no malloc'ing needed, so the
2510 {DEFER,ALLOW}_INTS thing removed.
2512 * numbers.h (struct scm_dbl): changed to represent a double cell,
2513 with the number in the second half.
2515 * dynwind.c: changed the wind-guards representation to double
2518 * procs.c, procs.h: changed the procedure-with-setter representation
2521 * async.c, async.h: made async representation a double cell.
2523 * dynl.c: made dynamic_obj representation a double cell.
2525 2000-03-13 Gary Houston <ghouston@arglist.com>
2527 * ports.c (flush_void_port): renamed to flush_port_default.
2528 (end_input_void_port): renamed to end_input_default.
2530 * init.c (scm_standard_stream_to_port): create a void port instead
2531 of opening /dev/null if the standard file descriptors are bad.
2532 advantages: no portability problems, doesn't waste a file descriptor,
2533 simplifies the code (thanks to Marius for the idea).
2535 * vports.c (s_scm_make_soft_port): call scm_port_non_buffer.
2537 * void ports: make reading from a void port give EOF instead of
2539 * ports.c (s_scm_sys_make_void_port): modified docstring.
2540 (fill_input_void_port): new proc.
2541 (scm_init_ports): set up fill_input_void_port.
2542 * ports.c (scm_port_non_buffer): new proc.
2543 (scm_void_port): call scm_port_non_buffer.
2545 * fports.c (scm_setvbuf): docstring: remove the fcntl documentation
2546 which was incorrectly appended.
2548 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2550 * guile-doc-snarf.in: Don't use absolute path for `sed'. (Note
2551 that we can't use autoconf for this. Autoconf itself relies on
2552 the existence of `sed' somewhere on your path.) (Thanks to Dirk
2555 2000-03-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2557 * Makefile.am (libguile_la_SOURCES): Moved iselect.c here from
2558 EXTRA_libguile_la_SOURCES.
2560 * iselect.h: Always declare scm_internal_select.
2562 * iselect.c (scm_internal_select): Added SCM_ASYNC_TICK at the
2563 end. Also let scm_internal_select be a real function also when
2566 * __scm.h (SCM_TICK): Oops! Forgot to put SCM_ASYNC_TICK here...
2568 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2570 * __scm.h (SCM_ALLOW_INTS, SCM_REALLOW_INTS): Removed call to
2571 SCM_ASYNC_TICK. (This is a preparation for POSIX threads support,
2572 and kind of an experiment: Will this cause problems?)
2574 Sun Mar 12 13:26:30 2000 Greg J. Badros <gjb@cs.washington.edu>
2576 * Makefile.am: Added *.doc to DISTCLEANFILES.
2578 2000-03-12 Gary Houston <ghouston@arglist.com>
2580 * fports.c (scm_fdes_to_port): call fcntl F_GETFL to test that
2581 the fdes is valid before doing anything else. check that
2582 the file descriptor supports the modes required.
2583 (scm_fport_buffer_add): don't throw an error if fstat doesn't
2584 work: just use the default buffer size.
2586 * throw.c: change an outdated comment about scm_internal_catch
2587 BODY: it doesn't take a jumpbuf arg.
2589 * init.c (scm_standard_stream_to_port): install a handler in case
2590 scm_fdes_to_port throws an error. don't check here whether the
2591 file descriptor is valid, since scm_fdes_to_port will do that.
2592 set the revealed count depending on whether the port got the
2593 standard file descriptor.
2594 (stream_body_data): new type.
2595 (stream_body, stream_handler): new procs.
2597 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2599 * stacks.c, stacks.h, struct.c, tags.h, unif.c (scm_bits_t):
2600 Renamed from SCMWORD.
2602 * tags.h (SCM_NCELLP): Removed (SCMWORD).
2604 * arbiters.c (SCM_ARB_LOCKED): Use SCM_UNPACK_CAR.
2606 * async.c, boolean.h, debug.c, dynl.c, dynwind.c, eval.c, eval.h,
2607 feature.h, filesys.h, fluids.h, fports.c, fports.h, gc.c, gc.h,
2608 hash.c, keywords.h, macros.c, numbers.c, numbers.h, objects.c,
2609 objects.h, options.c, pairs.h, ports.c, ports.h, print.c,
2610 procs.h, ramap.c, read.c, smob.c, smob.h, srcprop.h, stacks.c,
2611 stacks.h, strports.c, struct.c, struct.h, tag.c, tags.h,
2612 throw.c, unif.c, unif.h, variable.h, vectors.h, weaks.c,
2613 weaks.h (SCM_PACK, SCM_UNPACK, SCM_UNPACK_CAR): Renamed from
2614 SCM_ASSCM, SCM_ASWORD, SCM_CARW).
2616 * numbers.h (SCM_SRS, SCM_INUM): Corrected SCM_ASSCM/ASWORD fixes.
2618 * alist.c, eval.c, net_db.c, posix.c, print.c, snarf.h, struct.c,
2619 tags.h: Fixed copyright notices.
2621 * struct.c, coop-threads.c: SCM_ASSCM/ASWORD fixes.
2623 2000-03-12 Marius Vollmer <mvo@zagadka.ping.de>
2625 * init.c (scm_standard_stream_to_port): Check whether the file
2626 descriptor is valid and substitute "/dev/null" when not.
2628 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2630 * coop-defs.h (struct timespec): Conditionally defined.
2632 * coop.c (coop_condition_variable_timed_wait_mutex): Use ETIMEDOUT
2635 * readline.c (match_paren): Bugfix: First arg to select is not
2636 number of descriptors but the number of the highest descriptor +
2639 This is a preliminary attempt at a cleanup of the threads support
2640 code. It moves things to better places, makes arguments more
2641 consistent with the POSIX API (which is used in GNOME's glib), and
2642 adds new functionality.
2644 * readline.c (scm_init_readline): Added new arg to scm_init_mutex.
2646 * coop-defs.h (scm_mutex_trylock): New macro: alias for
2648 (scm_cond_init): Changed definition to
2649 coop_new_condition_variable_init.
2651 * coop.c: #include <errno.h>
2652 (coop_timeout_qinsert): Moved here from iselect.c
2653 (coop_new_mutex_init, coop_new_condition_variable_init): New
2654 functions. The strange names are temporary. Use scm_mutex_init
2655 and scm_cond_init instead.
2656 (coop_mutex_trylock): New function. Uses errno.h:EBUSY. errno.h
2657 is ANSI C, but should we check for individual error codes in
2659 (coop_condition_variable_timed_wait_mutex): New function.
2660 (coop_key_create, coop_setspecific, coop_getspecific,
2661 coop_key_delete): New functions.
2663 * iselect.c (coop_timout_qinsert): Moved to coop.c
2665 2000-03-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2667 * pairs.h (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR,
2668 SCM_SETOR_CDR): Corrected SCM_ASSCM/WORD fixes.
2670 * tags.h (SCM_VOIDP_TEST): Renamed from VOIDP_TEST.
2673 * objects.h (SCM_CLASS_FLAGS, SCM_OBJ_CLASS_FLAGS,
2674 SCM_SET_CLASS_INSTANCE_SIZE), struct.h (SCM_STRUCT_VTABLE_DATA),
2675 proc.h (SCM_CLOSCAR): SCM_ASSCM/WORD fixes.
2677 * eval.c (scm_lookupcar1): Inserted SCM_ASWORD in expressions
2680 2000-03-11 Dale P. Smith <dpsm@en.com>, applied by Greg J. Badros, <gjb@cs.washington.edu>
2682 * numbers.c (scm_copy_big_dec, scm_copy_smaller, scm_big_ior,
2683 scm_big_xor, scm_big_and, scm_big_test): Added new lowlevel bignum
2684 logical functions from SCM.
2686 (logand, logior, logxor, logtest, logbit?): Extended scheme
2687 logical functions to use bignums from SCM.
2689 (lognot): Removed call to `SCM_VALIDATE_INUM' that prevented
2690 lognot from using bignums.
2692 Thu Mar 9 11:33:25 2000 Greg J. Badros <gjb@cs.washington.edu>
2694 * vectors.h (SCM_VELTS_AS_STACKITEMS): Added this macro to help in
2695 eliminating some warnings.
2697 * unif.c, strports.c, print.c, options.c: Fix some warnings on
2700 * gc.c, gc.h: Added scm_return_first_int(), and added comment re:
2701 what the scm_return_first* functions do.
2703 2000-03-09 Han-Wen Nienhuys <hanwen@cs.uu.nl>, applied by Greg J. Badros, <gjb@cs.washington.edu>
2705 * libguile/*.[ch]: make a distinction between SCM as a generic
2706 name for a Scheme object (now a void*), and SCM as 32 bit word for
2707 storing tags and immediates (now a long int). Introduced
2708 SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious
2709 code in the process: arbiter.c (use macros), unif.c (scm_array_p),
2711 Wed Mar 8 10:15:59 2000 Greg J. Badros <gjb@cs.washington.edu>
2713 * numbers.c: Use SCM_VALIDATE_LONG_COPY, and longs, not ints, in
2714 various logXXX primitives. Thanks Eric Moore!
2716 Tue Mar 7 08:05:22 2000 Greg J. Badros <gjb@cs.washington.edu>
2718 * run-test, remaining-docs-needed: Added these scripts. The
2719 second one is only temporary until the docstring additions are
2720 complete. run-test may best live on, but is here mostly for
2721 convenience and awareness for now.
2723 * hash.c: Docs, minor cleanup patch from Dirk Herrman.
2725 Thu Mar 2 16:06:58 2000 Greg J. Badros <gjb@cs.washington.edu>
2727 * error.h, error.c: Added `scm_wrong_type_arg_msg' to support
2728 displaying the expected type. Use SCM_LISTn in a couple places
2729 instead of scm_cons-ing by hand.
2731 * __scm.h: Added SCM_ASSERT_TYPE macro.
2733 * validate.h, scm_validate.h: Added the former, as a renamed
2734 version of the latter with SCM_ASSERT_TYPE used in
2735 SCM_MAKE_VALIDATE (instead of just SCM_ASSERT)
2737 * Makefile.am: Rename scm_validate.h to validate.h.
2739 * *.c, *.h: Include validate.h, not scm_validate.h (old name's
2740 prefix was superfluous).
2742 Thu Mar 2 15:33:12 2000 Greg J. Badros <gjb@cs.washington.edu>
2744 * hashtab.c: Improved documentation for lots of functions. Added
2745 handwritten docs for `hash-fold'.
2747 Thu Mar 2 15:13:25 2000 Greg J. Badros <gjb@cs.washington.edu>
2749 * list.c: Added hand-written docs for `del{q,v,ete}1!'.
2751 Thu Mar 2 12:38:30 2000 Greg J. Badros <gjb@cs.washington.edu>
2753 * list.c: Moved append docs to append! Thanks Dirk Hermann. Also,
2754 added append docs from R4RS.
2756 * strings.c: Docstring typo fix, + eliminate unneeded IMP tests.
2757 Thanks Dirk Hermann!
2759 * chars.h: Provide SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR and
2760 deprecate SCM_ICHRP, SCM_ICHR, SCM_MAKICHR. Thanks Dirk Hermann!
2762 * *.h, *.c: Use SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR throughout.
2763 Drop use of SCM_P for function prototypes... assume an ANSI C
2764 compiler. Thanks Dirk Hermann!
2766 Sat Feb 19 12:20:12 2000 Greg J. Badros <gjb@cs.washington.edu>
2768 * ports.c: Made `set-port-column!' and `set-port-line!' each
2769 return SCM_UNSPECIFIED instead of a (not-scheme-object) integer
2770 that caused a seg fault. Also fixed `set-port-column!'s
2771 docstring. Thanks Han-Wen Nienhuys for finding the bug!
2773 Sun Feb 13 19:11:42 2000 Greg J. Badros <gjb@cs.washington.edu>
2775 * arbiters.c, eq.c, gc.c, guardians.c, list.c, ports.c, print.c,
2776 regex-posix.c, scmsigs.c, stime.c, strings.c, variable.c, stime.c,
2777 strings.c, variable.c: Added lots of documentation, cleaned up
2778 some existing documentation. Occasionally changed formal params
2779 to match docs. Also folded an #ifdef into the inners of a
2780 primitive instead of having two copies of the primitive
2781 (`get-internal-real-time', from stime.c)
2783 Sun Feb 13 18:12:19 2000 Greg J. Badros <gjb@cs.washington.edu>
2785 * ports.c: Added docs for primitives missing them. Written by
2788 Sun Feb 13 09:40:36 2000 Greg J. Badros <gjb@cs.washington.edu>
2790 * guile-doc-snarf.in: Use ${AWK} -f guile-func-name-check, not
2791 just execing guile-func-name-check. Thanks Michael Livshin!
2793 Thu Feb 10 11:43:23 2000 Greg J. Badros <gjb@cs.washington.edu>
2795 * guile-snarf.awk.in: Tweak to work with Sun/HP awk, removed some
2796 dead code. Patch from Michael Livshin.
2798 * guile-doc-snarf.in: Tweak to work with Sun/HP sh. Patch from
2801 2000-02-09 Gary Houston <ghouston@arglist.com>
2803 * init.c (scm_init_standard_ports): when stdout is a tty, make the
2804 current-output-port unbuffered by default. this is less confusing
2805 for interactive use. it was line-buffered because of a
2806 performance problem with unbuffered ports, but I think it will be
2809 2000-02-08 Gary Houston <ghouston@arglist.com>
2811 * __scm.h: don't define long_long or ulong_long if HAVE_LONG_LONGS
2814 * stime.c (scm_localtime, scm_mktime): if neither HAVE_TM_ZONE nor
2815 HAVE_TZNAME are defined, use an empty string instead of giving two
2816 spurious compile-time errors.
2818 Tue Feb 8 13:57:46 2000 Greg J. Badros <gjb@cs.washington.edu>
2820 * ports.c: Doc patches from Richard Kim. Pasted from MIT Scheme.
2823 Mon Feb 7 09:07:31 2000 Greg J. Badros <gjb@cs.washington.edu>
2825 * macros.c: Doc patches from Richard Kim. Pasted from scm.texi.
2827 Sun Feb 6 20:26:21 2000 Greg J. Badros <gjb@cs.washington.edu>
2829 * pairs.c: Doc patches from Richard Kim. Pasted from MIT Scheme
2830 (which is GNU GPL'd).
2832 2000-01-31 Gary Houston <ghouston@arglist.com>
2834 * strings.h: don't use SCM_P. don't include <string.h>.
2835 * error.c, gh_data.c, ports.c, script.c, strop.c: include <string.h>.
2837 * strings.c (scm_string_ref): make the 2nd argument compulsory.
2838 previously it defaulted to zero for no good reason that I can see.
2839 use a local variable for SCM_INUM (k). replace
2840 SCM_VALIDATE_INUM_DEF with SCM_VALIDATE_INUM_COPY.
2842 (scm_makfromstr): cosmetic changes.
2844 (scm_string): Accept only chars in the list, not strings, for
2845 conformance to R5RS (particularly for list->string, which is
2846 supposed to be the inverse of string->list.) remove
2847 SCM_DEFER_INTS/SCM_ALLOW_INTS, which is unnecessary since
2848 scm_makstr handles the cell allocation. when reporting wrong-type
2849 arg, don't report the position as 1.
2851 * posix.c (scm_init_posix): intern PIPE_BUF if it's defined.
2853 2000-01-29 Gary Houston <ghouston@arglist.com>
2855 * posix.c (scm_pipe): rewrote the docstring.
2857 * filesys.c (scm_select, retrieve_select_type, get_element,
2858 fill_select_type, set_element): modified so that Scheme
2859 "select" tests port buffers for the ability to provide input
2860 or accept output. Previously only the underlying file descriptors
2861 were checked. Rewrote the docstring.
2863 Thu Jan 27 10:14:25 2000 Greg J. Badros <gjb@cs.washington.edu>
2865 * vectors.c, symbols.c, strorder.c: Documentation cut and pasted
2866 from Gregg Reynolds. Thanks Gregg!
2868 Thu Jan 27 09:59:38 2000 Greg J. Badros <gjb@cs.washington.edu>
2870 * strop.c (scm_i_index): Obfuscated commented-out SCM_DEFINE by
2871 adding "x" prefix to the line so that guile-func-name-check
2872 doesn't complain unnecessarily.
2874 Wed Jan 26 17:33:52 2000 Greg J. Badros <gjb@cs.washington.edu>
2876 * throw.c: Factor out an #ifdef/#else/#endif choice more finely
2877 for maintainability.
2879 * strop.c: Documentation added by Gregg A. Reynolds. Pasted in
2882 Wed Jan 26 10:02:11 2000 Greg J. Badros <gjb@cs.washington.edu>
2884 * tag.c: Added doc for `tag', but mark as deprecated since Mikael
2885 suggests removing tag.c altogether (and using a new `class-of'
2888 * strings.c: Added documentation from Gregg A. Reynolds. Edited
2889 a bit by me to use FOO instead of @var{foo} and to have the
2890 summary come before preconditions on input. Also dropped trailing
2893 * gsubr.c: Do not use SCM_DEFINE for `gsubr-apply'. Register the
2894 function with scm_make_subr_opt w/ last arg of 0 so it is not
2895 visible at the Scheme level. Mikael says that this is the right
2896 thing because the first arg to the proc is the guts of a compiled
2897 closure and shouldn't be exposed to the Scheme level.
2899 Tue Jan 25 17:15:47 2000 Greg J. Badros <gjb@cs.washington.edu>
2901 * sort.c: typo in comment fixed.
2903 * keywords.c: Added documentation.
2905 * guardians.c: Added documentation (could be better).
2907 * gc.c: Added docs for gc-set-debug-check-freelist.
2909 * eq.c: Added docs for eq?, eqv? equal? abridged from R4RS.
2911 * boolean.c: Added docs for `not', `boolean?' (by hand).
2913 Tue Jan 25 13:28:56 2000 Greg J. Badros <gjb@cs.washington.edu>
2915 * random.c: Added documentation, from SLIB page:
2916 http://angela.ctrl-c.liu.se/~calle/scheme/slib_toc.html
2918 Mon Jan 24 17:50:20 2000 Greg J. Badros <gjb@cs.washington.edu>
2920 * variable.c, version.c: Added documentation, written by hand
2921 since I could not find anything already written that was
2924 2000-01-23 Gary Houston <ghouston@arglist.com>
2926 * filesys.c (scm_chown): omit port/fdes support if HAVE_FCHOWN is
2927 not defined (thanks to Richard Y. Kim).
2929 Thu Jan 20 13:00:38 2000 Greg J. Badros <gjb@cs.washington.edu>
2931 * Makefile.in: Removed, this is auto-generated.
2933 Thu Jan 20 11:33:47 2000 Dirk Hermann <dirk@ida.ing.tu-bs.de> --applied 01/20/00 gjb
2935 * list.c: Put some variable initialization code at the point of
2936 declaration; Added a comment for list*; Formatting changes.
2938 * load.c: use SCM_NNULLP to make sure the end of a list is not
2941 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2943 * backtrace.c (scm_display_error_message): Bugfix: Don't use
2944 result of scm_list_p as C boolean.
2945 (scm_display_error_message, scm_set_print_params_x): Use new
2946 validation macros. (Thanks to Dirk Herrmann.)
2948 * net_db.c (scm_resolv_error): Cast result from hstrerror.
2950 * strports.c (st_end_input): Inserted parenthesis to get operator
2953 * list.h (scm_init_list): Removed SCM_P around prototypes.
2955 * fports.c, list.c, numbers.c, ports.c, stime.c, symbols.c,
2956 filesys.c, posix.c: Converted docstrings to ANSI C format and
2957 escaped " occurring inside string literals.
2959 Tue Jan 18 13:21:08 2000 Mikael Djurfeldt <mdj@r11n07-s.pdc.kth.se>
2961 * posix.c (scm_mknod): Escape " occuring inside docstring.
2963 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2965 * alist.c, chars.c, debug.c, dynl.c, dynwind.c, error.c, eval.c,
2966 evalext.c, filesys.c, gc.c, hash.c, hashtab.c, ioext.c,
2967 keywords.c, list.c, load.c, macros.c, net_db.c, numbers.c,
2968 objprop.c, ports.c, posix.c, print.c, procprop.c, procs.c,
2969 ramap.c, regex-posix.c, root.c, scmsigs.c, simpos.c, socket.c,
2970 stacks.c, stime.c, strings.c, strop.c, strports.c, struct.c,
2971 symbols.c, throw.c, unif.c, vectors.c, version.c, vports.c,
2972 weaks.c: Converted docstrings to ANSI C format.
2974 * filesys.c (scm_chmod), simpos.c (scm_system), version
2975 (scm_version), vports (scm_make_soft_port): Escape " occuring
2978 Mon Jan 17 11:41:22 2000 Greg J. Badros <gjb@cs.washington.edu>
2980 * scm_validate.h: Added SCM_VALIDATE_ULONG_COPY,
2981 SCM_VALIDATE_LONG_COPY
2983 * numbers.c: Use SCM_VALIDATE_ULONG_COPY, instead of
2984 SCM_VALIDATE_INUM_COPY to let bigger numbers be used. Rename a
2985 couple of formal arguments (and fix their uses) to make arguments
2986 match the documentation.
2988 2000-01-14 <mstachow@alum.mit.edu>
2990 * Makefile.am: Augment path when running guile-doc-snarf so
2991 guile-func-name-check is found.
2993 Fri Jan 14 09:34:55 2000 Greg J. Badros <gjb@cs.washington.edu>
2995 * scm_validate.h (SCM_NUM2LONG_DEF): Fix this macro to just use
2996 def, not SCM_MAKINUM(def); thanks Janis Bzerins!
2998 Wed Jan 12 00:06:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3000 * net_db.c (s_scm_inet_makeaddr): Use SCM_NUM2ULONG since that's
3001 the way guile-1.3.4 worked, but #if 0 out the version using
3002 SCM_VALIDATE_INUM_COPY for stricter testing.
3004 Tue Jan 11 18:24:18 2000 Greg J. Badros <gjb@cs.washington.edu>
3006 * guile-doc-snarf.in: Use new $fullfilename for running
3007 guile-func-name-check, and put "$fullfilename" and "$filename" in
3008 quotes at uses to make sure re-splitting on whitespace does not
3009 occur (so filenames w/ embedded whitespace would work okay, though
3010 I sure hope we never have to deal with that! :-) ). Thanks to
3011 Mikael for pointing out the source_dir != build_dir was broken.
3013 Tue Jan 11 17:42:40 2000 Greg J. Badros <gjb@cs.washington.edu>
3015 * scm_validate.h: Added SCM_NUM2LONG_DEF macro. Make
3016 SCM_OUT_OF_RANGE use SCM_MAKINUM, not scm_long2num. Added
3017 SCM_COERCE_ROSTRING macro. Added SCM_VALIDATE_NONEMPTYLIST
3018 macro. Fix SCM_VALIDATE_STRINGORSUBSTR macro to not use SLOPPY
3021 * ports.c (scm_port_closed_p): Validate that the arg is a PORT,
3022 then return whether it's an open port (was validating that it was
3023 an open port -- this was a bug I introduced back in December, but
3024 my careful reading of diffs caught it).
3026 * numbers.c: Recombine the two conditional-compilation paths for
3027 all the log* primitives -- they were split based on #ifndef
3028 scm_long2num; factored out a SCM_LOGOP_RETURN macro, and fixed
3029 some bugs and inconsistencies in the two sets of implementations.
3030 (scm_lognot) Fixed *atrocious* re-use of a SCM as an integer!
3032 * ioext.c: Use SCM_ASSERT_RANGE in a couple places, and
3033 SCM_VALIDATE_INUM_COPY once where it should've been used.
3035 * fluids.c (scm_internal_with_fluids): Use
3036 SCM_VALIDATE_LIST_COPYLEN.
3038 * filesys.c: Use SCM_NUM2LONG instead of SCM_VALIDATE_INUM_COPY;
3039 this is questionable as it relaxes type safety, but other changes
3040 were useful and all SCM_NUM2LONG's should probably be
3041 revisited. Use SCM_OUT_OF_RANGE, SCM_WRONG_TYPE_ARG.
3043 * evalext.c: line-break change on 1 line.
3045 * eval.c (nconc2last): Takes a non-empty list as its first
3046 argument, not just a list.
3048 * dynl.c: Use new SCM_COERCE_ROSTRING macro.
3050 Tue Jan 11 15:44:23 2000 Greg J. Badros <gjb@cs.washington.edu>
3052 * dynl.c, feature.c, filesys.c, fports.c, list.c, load.c,
3053 net_db.c, sort.c, stacks.c, unif.c: Use SCM_WTA, SCM_MISC_ERROR
3056 * symbols.c (scm_sysintern0): Fixed the function name in a
3057 scm_misc_error invocation.
3059 * print.c (scm_simple_format): Do not need SCM_COERCE_SUBSTR, and
3060 use scm_return_first to ward off latent GC bug that Mikael caught.
3062 * async.c: Use SCM_VALIDATE_ASYNC_COPY one place where it wasn't
3063 used before but should've been.
3065 2000-01-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3067 * snarf.h (SCM_PROC1): Replaced SCM (*) (...) with
3068 SCM_FUNC_CAST_ARBITRARY_ARGS.
3070 Tue Jan 11 13:44:07 2000 Greg J. Badros <gjb@cs.washington.edu>
3072 * guile-func-name-check.in: Added this script to statically check
3073 #define FUNC_NAME, #undef FUNC_NAME in the source.
3075 * sort.c, posix.c: Fix #undef FUNC_NAME lines to not have trailing
3076 redundant comment, semicolon; caught by new guile-func-name-check
3079 * debug.c: Fix mistaken #define FUNC_NAME for scm_make_iloc.
3080 Caught by new guile-func-name-check-script.
3082 * Makefile.am: Added guile-func-name-check to bin_SCRIPTS
3084 * ramap.c: Fix #if 0'd out code to be syntactically acceptable to
3085 guile-func-name-check.
3087 * guile-doc-snarf.in: Run guile-func-name-check on the file before
3090 Tue Jan 11 11:31:10 2000 Greg J. Badros <gjb@cs.washington.edu>
3092 * fports.c, ports.c, ports.h, strports.c, vports.c: Make write
3093 port function take const void*, not void*.
3095 Tue Jan 11 11:18:07 2000 Greg J. Badros <gjb@cs.washington.edu>
3097 * scm_validate.h, chars.c, ports.c, print.c, read.c, strings.c,
3098 strop.c: Use SCM_VALIDATE_ICHR, SCM_VALIDATE_ICHR_COPY instead of
3099 SCM_VALIDATE_CHAR, SCM_VALIDATE_CHAR_COPY. Change made for
3100 consistency with the other macros dealing with immediate
3101 characters. (Similar to INT -> INUM change a week or so ago).
3103 Tue Jan 11 10:41:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3105 * dynl.c, error.c, eval.c, feature.c, filesys.c, fports.c, list.c, load.c,
3106 net_db.c, read.c, socket.c: Update error messages to use ~A for
3107 %s, ~S for %S to work with new `simple-format' format and be
3108 standardized better.
3110 * print.h, print.c (scm_simple_format): Added `simple-format'
3111 primitive. It's the old scm_display_error, with ARGS now a rest
3112 parameter, and the destination first instead of last (and a couple
3113 new capabilities inspired by `format' -- #t as destination means
3114 current-output-port, #f means return the formatted text as a
3117 * gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
3119 * backtrace.c (scm_display_error_message): Rewrote to use
3120 scm_simple_format() procedure.
3122 * __scm.h: Added commented-out #define of GUILE_DEBUG_FREELIST
3124 2000-01-09 Marius Vollmer <mvo@zagadka.ping.de>
3126 Finally applied the libltdl patch from Thomas Tanner, with slight
3129 * DYNAMIC-LINKING: Removed because it is obsolete.
3130 * dynl.c: Use ANSI prototypes.
3131 (sysdep_dynl_link): Use lt_dlopenext instead of lt_dlopen.
3132 * scmconfig.h.in: Do not change, as it is automatically generated.
3134 1999-07-25 Thomas Tanner <tanner@ffii.org>
3136 * dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c: deleted
3138 * Makefile.am: likewise, add INCLTDL (libltdl headers) to
3139 INCLUDES, set dlpreopened files in LDFLAGS, link libguile
3141 * dynl.c: use libltdl if DYNAMIC_LINKING is enabled,
3142 * guile.c: register preloaded modules
3143 * scmconfig.h.in: remove obsolete symbols
3145 2000-01-09 Gary Houston <ghouston@arglist.com>
3147 * These changes should make it unnecessary to call tzset from
3148 Scheme after modifying the TZ environment variable, even if the
3149 system date facilities cache the value.
3150 * stime.c (setzone, scm_localtime): added comments.
3151 (tzset): don't define a noop tzset macro if HAVE_TZSET not defined.
3152 (setzone): don't call tzset.
3153 (restorezone): call tzset only if HAVE_TZSET is defined.
3154 (scm_tzset): don't define if HAVE_TZSET not defined. Change the
3155 doc string to indicate that this procedure isn't likely to do
3157 (scm_localtime, scm_strftime, scm_mktime): call tzset if
3158 LOCALTIME_CACHE is defined.
3160 2000-01-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3162 * posix.c (scm_sync): Return SCM_UNSPECIFIED.
3164 2000-01-09 Gary Houston <ghouston@arglist.com>
3166 * eval.c: define scm_unbound_variable_key ('unbound-variable).
3167 scm_lookupcar1: throw an error with key 'unbound-variable instead
3168 of 'misc-error when an unbound variable is encountered.
3170 * filesys.c (scm_mkdir, scm_rmdir, scm_getcwd, scm_select,
3171 scm_symlink, scm_readlink, scm_lstat),
3172 posix.c (scm_setpgid, scm_setsid, scm_ctermid, scm_tcgetpgrp,
3173 scm_tcsetpgrp, scm_uname, scm_setlocale, scm_mknod, scm_nice,
3175 simpos.c (scm_system),
3176 stime.c (scm_times, scm_strptime):
3177 move the HAVE_XXX feature tests out of the procedure bodies.
3178 don't use SCM_SYSMISSING.
3179 scm_validate.h (SCM_SYSMISSING): removed.
3180 error.h, error.c (scm_sysmissing): comment that this is deprecated.
3181 see ChangeLog entry for 1999-12-28.
3183 Sat Jan 8 19:52:04 2000 Greg J. Badros <gjb@cs.washington.edu>
3185 * scm_validate.h (SCM_VALIDATE_BOOL_COPY): Fix typo.
3187 Sat Jan 8 17:06:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3189 * backtrace.c: Fix spelling typo in a comment.
3191 * snarf.h: Use new SCM_DOCS macro to encapsulate the non SCM_INIT
3192 text. Reformatted some of the expansions.
3194 Fri Jan 7 15:50:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3196 * scm_validate.h (SCM_OUT_OF_RANGE): Use scm_out_of_range_pos to
3197 report the position of the argument.
3199 * error.h, error.c (scm_out_of_range_pos): Added this function to
3200 take extra "pos" argument, the position number of the errant
3203 * debug.c: Use SCM_OUT_OF_RANGE instead of scm_out_of_range.
3205 * snarf.h: Use SCM_HERE and SCM_INIT as names, not SCM_NOTSNARF
3206 and SCM_SNARFING. Also put the %%% in the SCM_INIT since Mikael
3207 prefers that and I'm reasonably indifferent.
3209 Fri Jan 7 15:03:32 2000 Greg J. Badros <gjb@cs.washington.edu>
3211 * snarf.h: Factor out differences between C++ and non-C++ into
3212 SCM_FUNC_CAST_ARBITRARY_ARGS macro. Modify all the snarf macro
3213 definitions to use SCM_NOTSNARF and SCM_SNARFING macros (like
3214 Mikael's macros, below, but changed names and SCM_SNARFING no
3215 longer expands to include %%% -- that must appear in the argument
3216 so that the token appears at the call-site as a reminder).
3218 2000-01-07 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3220 * snarf.h (SCM_INSITU, SCM_INIT): New snarf macros for use in user
3221 snarf macro definitions.
3223 2000-01-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3225 * chars.c (scm_integer_to_char): Use Greg's nice
3226 SCM_VALIDATE_INUM_RANGE macro for argument checking for closer
3229 Thu Jan 6 11:48:49 2000 Greg J. Badros <gjb@cs.washington.edu>
3231 * *.c, snarf.h: Replace GUILE_PROC1 with SCM_DEFINE1 throughout.
3233 Thu Jan 6 11:22:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3235 * Makefile.am (ETAGS_ARGS): Switch to SCM_DEFINE, SCM_DEFINE1
3236 instead of GUILE_PROC.
3238 Thu Jan 6 11:21:49 2000 Greg J. Badros <gjb@cs.washington.edu>
3240 * alist.c: Do not report mismatch errors on some uses of `tmp' (do
3241 this by using SCM_ARG2 instead of `2' in the SCM_VALIDATE_CONS
3244 Thu Jan 6 09:54:33 2000 Dirk Herrmann <dirk@ida.ing.tu-bs.de> --gjb applied
3246 * scm_validate.h: Remove some redundant NIMP tests.
3248 * alist.c: minimize scope of the tmp variables, and initialize
3249 them when declared. The strange SCM_NIMP tests are replaced by
3250 SCM_CONSP tests that more closely reflect the intended semantics.
3251 However, we don't get a performance penalty here, because the
3252 SCM_CONSP test was performed by the ALISTCELL test anyway. * The
3253 extremely ugly use of ASRTGO macros was removed: The calls to
3254 ASRTGO were not encapsulated by "#ifndef SCM_RECKLESS", but got a
3255 label parameter that only exists when SCM_RECKLESS is not defined.
3256 This works, because ASRTGO itself is defined in a way that it only
3257 makes use of the label parameter if SCM_RECKLESS is not defined
3258 (shudder!). Does guile make at all use of the possibility to
3259 define SCM_RECKLESS? * Codesize is likely to be reduced, since
3260 instead of two calls to SCM_ASSERT performed by the ALISTCELL test
3261 we now only get one test.
3263 * list.c: Use SCM_NNULLP, not SCM_NIMP as appropriate. Also use
3264 SCM_NULLP instead of SCM_IMP. Drop use of "register" keyword on
3265 some variables in `list?'. Fix `reverse' and `reverse!'
3266 primitives to handle improper lists better.
3268 Wed Jan 5 11:24:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3270 * *.[ch]: Whitespace changes -- added space after SCM_VALIDATE_*
3271 macros and SCM_DEFINE macros to match GNU coding standards.
3273 Wed Jan 5 11:04:24 2000 Greg J. Badros <gjb@cs.washington.edu>
3275 * *.[ch]: Replace GUILE_PROC w/ SCM_DEFINE.
3277 Wed Jan 5 10:59:06 2000 Greg J. Badros <gjb@cs.washington.edu>
3279 * *.[ch]: Replace SCM_VALIDATE_INT w/ SCM_VALIDATE_INUM for
3280 better consistency with the names of other SCM_VALIDATE_ macros
3281 and better conformance to guile naming policy.
3283 Wed Jan 5 10:50:39 2000 Greg J. Badros <gjb@cs.washington.edu>
3285 * ports.c (s_scm_close_all_ports_except): Use SCM_ARG1 in a
3286 SCM_VALIDATE instead of 1 to avoid a check on the argument (since
3287 it's not the actual name of the formal).
3289 * guile-snarf.awk.in: Do argument/number mismatch checking and
3290 print warnings in an Emacs compile-mode parseable format.
3292 * struct.c: Use SCM_ASSERT_RANGE instead of SCM_ASSERT w/
3293 SCM_OUTOFRANGE as 3rd argument.
3295 * random.c: Fix argument/number mismatch (that I introduced :-( ).
3297 * __scm.h: Do not #define SCM_ARG* when snarfing;
3298 lets us distinguish between 1 and SCM_ARG1 when snarfing as only
3299 the former (using the number) requires the argument to match the
3300 formal in the current argument snarfing check.
3302 * snarf.h: Give new definition of SCM_ASSERT when in
3303 snarfing mode to output a lexically-identifiable sequence that the
3304 guile-snarf.awk script uses to verify argument/position matching.
3306 * ramap.c: Remove extraneous #undef FUNC_NAME.
3308 Wed Jan 5 08:36:38 2000 Greg J. Badros <gjb@cs.washington.edu>
3310 * guile-doc-snarf.awk.in: Removed -- guile-snarf.awk.in is the
3311 current version of the same functionality; it writes the .x output
3312 to stdout instead of directly into the file.
3314 Wed Jan 5 08:15:04 2000 Greg J. Badros <gjb@cs.washington.edu>
3316 * unif.c, symbols.c, strings.c, stacks.c, random.c, print.c,
3317 posix.c: Eliminated a bunch of SCM_NIMP(..)s that are now
3318 redundant with the safer macros. Patch from Dirk Hermann applied
3319 by hand. Thanks Dirk!
3321 * scm_validate.h: Added SCM_VALIDATE_VECTOR_OR_DVECTOR for some
3324 * ramap.c: whitespace change.
3326 Tue Jan 4 14:21:35 2000 Greg J. Badros <gjb@cs.washington.edu>
3328 * options.c, objects.c, keywords.c, gc.c: Some redundant SCM_NIMP
3329 removals from Dirk Hermann.
3331 * alist.c: Rename formals to match the parameter names in the
3332 documentation, updates to documentation. Thanks Dirk Hermann!
3334 2000-01-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3336 * eval.c (SCM_CEVAL): Reverse order of
3337 scm_stack_checking_enabled_p and SCM_STACK_OVERFLOW_P
3338 (Thanks to Brad Knotwell.)
3340 Mon Jan 3 08:30:02 2000 Greg Harvey <Greg.Harvey@thezone.net> (applied --01/03/00 gjb)
3342 * gc.c (scm_debug_newcell): Added SCM_SETCAR of the newly
3345 * pairs.h: Added a comment about the need for the SCM_SETCAR in
3348 Mon Jan 3 08:25:19 2000 Greg J. Badros <gjb@cs.washington.edu>
3350 * dynl-vms.c, debug.c, coop-threads.c, backtrace.c, eval.c: More
3351 SCM_NIMP tests that were redundant are now eliminated. Patches
3352 from Dirk Hermann applied by hand.
