1 2000-07-24 Marius Vollmer <mvo@zagadka.ping.de>
3 * stime.c (scm_strftime): Recognize a return value of zero from
4 strftime as buffer overflow and take care to detect a valid zero
5 length result regardless. Thanks to David Barts!
7 2000-07-23 Marius Vollmer <mvo@zagadka.ping.de>
9 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
10 scm_assoc_remove_x): Remove all cells whose key is eq, eqv, or
11 equal (respectively) to the argument key, not all cells that are
12 eq, eqv, or equal to the first cell with the argument key. Thanks
15 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
17 * gc.h (SCM_FREE_CELL_CDR, SCM_SET_FREE_CELL_CDR), hooks.c
18 (make_hook), modules.c (OBARRAY, USES, BINDER): Pack and unpack
19 SCM values appropriately.
21 * modules.c (scm_standard_eval_closure): Don't pass an inum to
22 scm_makcclo, but rather a long value.
24 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
26 read.c (scm_lreadrecparen), srcprop.c (scm_set_source_property_x):
27 SCM_SETCDR and SCM_WHASHSET macros don't deliver a return value.
28 Thanks to Han-Wen Nienhuys for the bug report.
30 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
32 * root.[ch] (scm_call_catching_errors): Deprecated.
34 * root.c (scm_init_root): Initialize the root smob type using the
35 standard initialization functions.
37 2000-07-17 Marius Vollmer <mvo@zagadka.ping.de>
39 * eval.c (unmemocopy): Don't rely on V being a list of at least
40 one element. Thanks to Bill Schottstaedt!
42 2000-07-15 Michael Livshin <mlivshin@bigfoot.com>
44 * gc.c (scm_done_free): new.
45 expanded comments about scm_done_malloc.
47 * gc.h: added prototype for scm_done_free
49 2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
51 * gc.h (scm_take_stdin): Removed.
53 * gc.h (SCM_VALIDATE_CELL): Delegate cell checks to function
54 scm_assert_cell_valid to allow extensions to the checking
55 functionality without need to recompile everything.
57 * gc.[ch] (scm_assert_cell_valid, scm_set_debug_cell_accesses_x):
58 Added as conditionally compiled functions for the case that
59 SCM_DEBUG_CELL_ACCESSES is enabled.
61 * gc.c (debug_cells_p): Added to indicate whether compile-time
62 included cell access debugging is run-time enabled.
64 * gc.[ch] (scm_gc_running_p): Added to indicate that scm_igc is
65 being executed. Intended to be used instead of scm_gc_heap_lock
68 * error.c (scm_error), gdbint.c (SCM_GC_P): Use scm_gc_running_p
69 instead of scm_gc_heap_lock.
71 * gc.c (scm_igc): Set scm_gc_running_p to true while running.
73 * gc.c (scm_mark_locations): Don't mark free cells.
75 * weaks.c (scm_scan_weak_vectors): Use SCM_FREE_CELL_P instead of
78 2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
80 * gc.c (scm_mark_locations): Minimized some variable scopes and
81 simplified the code a bit.
83 2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
85 * gc.h (SCM_SET_FREE_CELL_TYPE, SCM_SET_FREE_CELL_CDR,
86 SCM_FREE_CELL_P, SCM_FREE_CELL_CDR): Added since free cells
87 should not be accessed via SCM_C[AD]R. Further, using dedicated
88 macros to access free cells allows all other cell accessing macros
89 to treat acesses to free cells as errors, thus enabling better
90 error checks for cell accesses. SCM_FREE_CELL_P is supposed to
91 replace SCM_FREEP some time.
93 * gc.h (SCM_NEWCELL, SCM_NEWCELL2), gc.c (map_free_list,
94 free_list_length, scm_check_freelist, scm_debug_newcell,
95 scm_debug_newcell2, freelist_length, scm_gc_for_newcell,
96 scm_gc_mark, scm_gc_sweep, init_heap_seg): Only use the dedicated
97 cell accessors when accessing free cells.
99 2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
101 * gc.h (SCM_CELL_WORD, SCM_CELL_OBJECT): Treat the referenced
102 object as const in order to make the compiler warn about code like
103 SCM_CELL_WORD (x, n) = y. Instead, SCM_SET_CELL_WORD (x, n, y)
106 (SCM_CELL_WORD_LOC, SCM_CARLOC, SCM_CDRLOC): Return the address
107 as an address to a non-const object, since these macros are used
108 to allow direct write access to objects.
110 2000-07-07 Dirk Herrmann <D.Herrmann@tu-bs.de>
112 * hashtab.c (scm_hash_fn_create_handle_x): Signal an error if the
113 given hash table has no slots.
115 2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
117 * gc.c (policy_on_error): Added in order to allow alloc_some_heap
118 to react to malloc failures in a context dependent way.
120 (scm_check_freelist): No need to flush streams before abort().
122 (scm_gc_for_newcell): Try to allocate new memory in three phases:
123 grow heap if preferred, if still no memory available collect
124 garbage, if still no memory available grow heap.
126 (heap_segment_table_size): Added to always reflect the actual
127 size of the heap segment table, because scm_n_heap_segs may differ
128 from the heap segment table size.
130 (alloc_some_heap): In case of malloc failure, react according to
131 the new policy_on_error parameter (either return to caller or
132 abort immediately). Further, keep heap_segment_table_size up to
135 (scm_init_storage): Initialize heap_segment_table_size.
137 2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
139 * gh.h: Don't include <stdio.h>. Thanks to Han-Wen Nienhuys for
142 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
144 * __scm.h (SCM_OUTOFRANGE, SCM_NALLOC, SCM_HUP_SIGNAL,
145 SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL, SCM_SEGV_SIGNAL,
146 SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL, SCM_SIG_ORD,
147 SCM_ORD_SIG, SCM_NUM_SIGS): Re-introduce these as deprecated
150 * error.c (scm_wta): Re-introduce dispatching for SCM_OUTOFRANGE
151 and SCM_NALLOC, but as a deprecated feature.
153 2000-06-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
155 * debug.c: Added #include fluids.h.
157 * numbers.c (scm_gr_p, scm_leq_p, scm_geq_p): Turned into
158 primitive generics. (Thanks to Nicolas Neuss.)
160 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
162 * gc.c (alloc_some_heap): Use scm_memory_error to indicate a
163 failed attempt to get additional memory from the system.
165 (scm_gc_for_newcell): Changed the control structure to make the
166 behaviour explicit for the case that gc is not able to free any
169 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
171 * __scm.h (SCM_OUTOFRANGE): Removed.
173 * error.c (scm_wta): Removed sick dispatch code for range
174 errors. (More sick dispatches still to be removed.)
176 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
177 scm_hash_fn_remove_x): Eliminate redundant test for if unsigned
178 value is non-negative. Use scm_out_of_range to signal range
181 * hooks.c (make_hook), unif.c (scm_aind): Use scm_out_of_range to
184 * list.c (scm_list_ref, scm_list_set_x, scm_list_cdr_set_x): Fix
185 error reporting (now uses original input parameter to report wrong
186 type argument errors). Use SCM_OUT_OF_RANGE to report range
187 errors and SCM_WRONG_TYPE_ARG to report type errors.
189 * strings.c (scm_substring): Make range checks for negative
190 values explicit (former behaviour relied on an implicit
191 conversion from signed to unsigned). Don't use SCM_ASSERT for
194 * unif.c (scm_aind, scm_transpose_array, scm_bit_set_star_x,
195 scm_bit_count_star): Use scm_out_of_range to signal range
198 * unif.c (scm_transpose_array, scm_bit_position), vectors.c
199 (scm_vector_ref, scm_vector_set_x, scm_vector_move_left_x,
200 scm_vector_move_right_x): Use SCM_ASSERT_RANGE to check ranges.
202 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
204 * validate.h (SCM_VALIDATE_INUM_MIN_COPY,
205 SCM_VALIDATE_INUM_MIN_DEF_COPY, SCM_VALIDATE_INUM_RANGE_COPY):
206 Perform all range checks based on the input value. The former way
207 of using the value that is assigned to the target variable fails
208 if the assignment to the target variable itself can change the
209 value because of type conversion.
211 (SCM_ASSERT_RANGE): Use scm_out_of_range to signal range errors.
213 2000-06-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
215 * gc.c (scm_gc_for_newcell): Behave gracefully also if scm_igc
216 doesn't yield any new cells. In theory this could happen if all
217 cells allocated with NEWCELL are either in use or conservatively
218 marked and all cluster spine cells are conservatively marked.
221 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
223 * __scm.h (SCM_NALLOC): Removed.
225 * error.c (scm_wta): Removed sick dispatch code for memory
226 errors. (More sick dispatches still to be removed.)
228 * numbers.c (scm_mkbig, scm_adjbig), ports.c (scm_make_port_type),
229 random.c (scm_i_copy_rstate, scm_c_make_rstate), smob.c
230 (scm_make_smob_type), srcprop.c (scm_make_srcprops), vectors.c
231 (scm_vector_set_length_x): Now using scm_memory_error to signal
234 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
236 * __scm.h: Removed some commented code and fixed some comments.
238 (SCM_HUP_SIGNAL, SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL,
239 SCM_SEGV_SIGNAL, SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL,
240 SCM_SIG_ORD, SCM_ORD_SIG, SCM_NUM_SIGS): Removed.
242 * async.c: Removed some commented code.
244 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
246 * gc.c (scm_gc_mark, scm_gc_sweep, scm_must_malloc,
247 scm_must_realloc, scm_must_free, alloc_some_heap): Use the
248 appropriate error signalling function.
250 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
252 * root.h (scm_first_type): Removed.
254 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
256 * gc.c (MIN_GC_YIELD): Removed.
258 2000-06-28 Michael Livshin <mlivshin@bigfoot.com>
260 * gc.c (scm_gc_for_newcell): don't try to do GC if it's blocked,
263 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
265 * async.c (scm_gc_async, scm_gc_vcell, scm_sys_gc_async_thunk):
268 (scm_init_async): Moved initialization for scm_gc_async and
269 scm_gc_vcell to gc.c. Moved initialization of scm_asyncs here
272 * async.h (scm_gc_async): Not globally visible any more.
274 * gc.c (scm_gc_stats): Made callable even from within regions
277 (scm_gc_end): Eliminate the hardcoding of the marking of the
278 scm_gc_async from the gc core.
280 (scm_init_storage): Don't initialize the scm_asyncs list here.
281 This is now done in asyncs.c.
283 (scm_gc_vcell): Moved here from async.c.
285 (gc_async): Renamed from scm_gc_async, moved here from async.c
288 (gc_async_thunk): Renamed from scm_sys_gc_async_thunk and moved
291 (mark_gc_async): New hook function for scm_after_gc_c_hook.
293 (scm_init_gc): Added initialization of scm_gc_vcell and
294 gc_async. Further, add mark_gc_async to scm_after_gc_c_hook.
296 * init.c (scm_boot_guile_1): scm_init_gc requires asyncs to be
299 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
301 * gc.c (scm_igc): Removed commented code that once was intended
302 to unprotect struct types with no instances.
304 * root.h (scm_type_obj_list): Removed.
306 2000-06-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
308 * async.c (scm_init_async): Switch to standard way of smob
311 2000-06-21 Michael Livshin <mlivshin@bigfoot.com>
313 * guile-doc-snarf.in: use cut instead of sed, that's much much
314 faster. also, don't call basename more than needed. and, to gain
315 a couple of microseconds more, don't call cat needlessly. (thanks
318 2000-06-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
320 * guile-snarf.awk.in, guile-snarf.in, snarf.h: Rename SCM__I to
321 SCM_SNARF_INIT_START, SCM__D to SCM_SNARF_DOC_START, SCM__S to
322 SCM_SNARF_DOCSTRING_START and SCM__E to SCM_SNARF_DOCSTRING_END.
324 2000-06-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
326 * eval.c, eval.h (scm_top_level_lookup_closure_var): Added.
327 #include "libguile/fluids.h".
329 * eval.h (SCM_TOP_LEVEL_LOOKUP_CLOSURE): New macro which replaces
330 SCM_CDR (scm_top_level_lookup_closure_var) everywhere.
332 * root.h (scm_top_level_lookup_closure_var,
333 scm_system_transformer): Removed. (It's no sense in having the
334 *variable* be a "fluid".)
336 * root.c (mark_root): Removed marking of
337 s->top_level_lookup_closure_var and s->system_transformer.
339 * modules.c (scm_selected_module): the_module is now a fluid.
341 2000-06-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
343 * gc.h, tags.h: Be kind to compilers which must see hash signs in
344 column 0. (Thanks to Ian Grant.)
346 * numbers.h: Put #ifdef HAVE_LONG_LONGS around declarations using
347 the long_long type. (Thanks to Bernard Urban.)
349 2000-06-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
351 * gc.c, gc.h (scm_default_init_heap_size_1,
352 scm_default_min_yield_1, scm_default_init_heap_size_2,
353 scm_default_min_yield_2, scm_default_max_segment_size): New global
354 variables. Can be customized by the application before booting
355 Guile. (We might want to be able to control these parameters
356 dynamically through the "options interface" in the future, but
357 note that that is additional functionality. Here we're giving
358 default values which the environment variables can override.)
360 * list.c (scm_cons_star): Updated comment.
362 * smob.h: Changed comments for scm_make_smob_type and
363 scm_make_smob_type_mfpe, warning that the latter might be
364 deprecated in a future release.
366 2000-06-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
368 * list.[ch] (scm_cons_star/cons*): Renamed from
371 * list.[ch] (scm_list_star/list*): Provided as a deprecated alias
372 for scm_cons_star/cons*.
374 * gc.c (scm_protect_object): Updated comment.
376 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX): Removed.
378 * tags.h (SCM_UNPACK_CAR, SCM_NDOUBLE_CELLP): Removed.
380 2000-06-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
382 * init.c, init.h (scm_initialized_p): Renamed from `initialized'
385 * gdbint.c (gdb_print): Print warning instead of calling scm_write
386 if Guile isn't yet initialized.
388 * print.c (scm_current_pstate, scm_make_print_state): Simplified
389 tests, using the assumption that Guile has been initialized.
391 Sun Jun 18 14:45:21 2000 Greg J. Badros <gjb@cs.washington.edu>
393 * print.c (s_scm_current_pstate): Do not segfault when the
394 print_state_pool is unitialized in `current-pstate', and better
395 verify its state before altering it in scm_make_print_state().
397 2000-06-18 Michael Livshin <mlivshin@bigfoot.com>
399 * scmsigs.c (s_scm_sigaction): guard the SIGIOT case with an
400 #ifdef -- it's missing on at least one platform. (thanks to
403 2000-06-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
405 * list.c (list*): Added documentation from common-list.scm.
407 2000-06-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
409 * gc.c (scm_unprotect_object): The reference count is guaranteed
410 to be a positive number.
412 2000-06-15 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
414 * eval.c: Updated comment above scm_map.
416 2000-06-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
418 * gc.c (scm_protect_object): Avoid looking up the object handle
420 (scm_unprotect_object): Abort if scm_unprotect_object is called on
421 an unprotected object.
423 2000-06-14 Michael Livshin <mlivshin@bigfoot.com>
425 * gc.c (scm_unprotect_object): fix a nasty typo bug (thanks to
428 2000-06-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
430 * socket.c (scm_getsockopt): Changed type for `optlen' from int to
432 (scm_accept, scm_getsockname, scm_getpeername, scm_recvfrom):
433 Ditto for `tmp_size'.
434 (scm_addr_buffer_size): Changed type from int to size_t.
436 * random.c: #include <string.h>. (Needed by memcpy.)
438 * guile-snarf.awk.in: Replace the dot_doc_file arg with "-",
439 indicating stdin, instead of "" and don't reset ARGC. This is a
440 workaround for `nawk' in AIX 4.3 on RS6000 but, as far as I know,
441 it is correct, and perhaps even better.
443 2000-06-14 Gary Houston <ghouston@arglist.com>
445 * scmsigs.c (scm_init_scmsigs): if HAVE_SIGINTERRUPT is not
446 defined, add SA_RESTART to the sigaction flags correctly
447 (thanks to Dale P. Smith).
449 2000-06-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
451 * strings.c: #include <string.h>. (Thanks to Bill Schottstaedt.)
453 * net_db.c (scm_resolv_error): Only use macro NETDB_INTERNAL if
454 defined. It isn't on sgi irix 5.3. (Thanks to Bill Schottstaedt.)
456 * Makefile.am (.c.doc): Pipe output (the .x contents) to /dev/null.
458 2000-06-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
460 * fports.c (scm_setvbuf): Use `free' instead of `scm_must_free'
461 since read and write buffers are allocated by `malloc'.
463 * Makefile.am: Removed old test code.
465 * gh_test_c.c, gh_test_repl.c: Removed.
467 2000-06-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
469 * iselect.c (SCM_NLONGBITS): Add workaround for the Sun 4.2
472 * inet_aton.c (inet_aton): Cast init value for `cp'.
474 * ramap.c (s_scm_array_fill_x): Cast `ve' properly in case
477 * symbols.c (scm_intern_obarray_soft,
478 scm_sysintern0_no_module_lookup): Cast `name' to unsigned char ptr
479 in calls to scm_strhash.
481 * strports.c (st_resize_port): Substituted SCM_UCHARS for
483 (st_write): Cast argument to strncpy to char ptr.
484 (scm_mkstrport): Substituted SCM_ROUCHARS for SCM_ROCHARS.
485 (scm_strport_to_string): Cast argument to scm_makfromstr to char
488 * ports.c (scm_ungetc): Cast value to unsigned char ptr before
489 storing in putback_buf.
490 (scm_unread_string): Substituted SCM_ROCHARS for SCM_ROUCHARS.
492 * ioext.c (s_scm_read_line): Cast result of call to
493 scm_do_read_line to unsigned char ptr.
495 * gdbint.c (SEND_STRING): Cast argument to char pointer.
497 * fports.c (fport_flush): Declare `ptr' as unsigned char (was
500 * Makefile.am (DOT_DOC_FILES): List doc-files explicitly. (We
501 shouldn't use Make rules which aren't supported by most Make
503 (OMIT_DEPENDENCIES): Defined to "libguile.h ltdl.h". (We don't
504 want these dependencies recorded, since they would get bogus
505 relative paths; libguile.h is only used in gh.h and guile.c.)
506 (EXTRA_DOT_X_FILES, EXTRA_DOT_DOC_FILES): New variables.
507 (guile-procedures.txt): Depend on EXTRA_DOT_DOC_FILES.
508 (modinclude_HEADERS): Removed kw.h.
510 * guile-snarf.in: Change regexp "^SCM__I" --> "^ *SCM__I".
511 (The preprocessor might insert spaces before the identifier.)
513 * snarf.h (SCM_SNARF_HERE, SCM_SNARF_INIT, SCM_SNARF_DOCS):
514 Renamed from SCM_HERE, SCM_INIT, SCM_DOCS.
516 * smob.h (scm_smobfuns): Removed deprecated type.
518 * smob.c, smob.h (scm_newsmob): Removed deprecated function.
519 (Replaced by `scm_make_smob_type'.)
521 * keywords.c (scm_tc16_kw): Removed deprecated type.
522 (Replaced by scm_tc16_keyword.)
524 * kw.h: Removed deprecated header file.
526 * evalext.c (serial-map): Removed deprected alias for scm_map.
527 (Has been replaced by `map-in-order'.)
529 * ramap.c (serial-array-copy!, serial-array-map!): Removed
530 depracted aliases. (Replaced by `array-copy-in-order!' and
531 `array-map-in-order'.)
533 2000-06-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
535 * gc.h (SCM_VALIDATE_CELL): Rewritten.
536 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
537 SCM_SET_CELL_OBJECT): Use new version of SCM_VALIDATE_CELL.
538 (Thanks to Han-Wen Nienhuys.)
540 2000-06-10 Michael Livshin <mlivshin@bigfoot.com>
542 * guile-doc-snarf.in: don't pipe the CPP output right into sed --
543 write it to the temp file first and check the CPP return code.
544 (I introduced this bug earlier, and this probably caused people
545 with non-GNU C preprocessors to get empty *.x files and not to
546 have the build fail right away...).
548 * scmsigs.c (s_scm_sigaction): guard the SIGSYS case with an ifdef
549 -- at least my libc5-based Linux system doesn't define SIGSYS.
551 2000-06-08 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
553 * snarf.h, guile-snarf.awk.in, guile-snarf.in: Replaced snarf
554 markers with identifiers (SCM__I, SCM__D, SCM__S, SCM__E).
555 (Thanks to Bernard Urban.)

559 * modules.c (scm_system_module_env_p): Fixed detection of system
562 2000-06-06 Marius Vollmer <mvo@zagadka.ping.de>
564 * scmsigs.c (scm_sigaction): Silently ignore setting handlers for
565 `program error signals' because they can't currently be handled by
568 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
570 * procs.h (SCM_SET_SUBRF): Added.
572 * procs.c (scm_make_subr_opt): Don't assign to SCM_SUBRF, use
573 SCM_SET_SUBRF instead. Thanks to Bernard Urban for the bug
576 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
578 * gc.h (SCM_CARLOC, SCM_CDRLOC): Don't take the address of a SCM
581 * sort.c (scm_sorted_p, scm_merge, scm_merge_list_x,
582 scm_merge_list_step): Don't take the address of SCM_CAR. Use
583 SCM_CARLOC instead. Thanks to Bernard Urban for the bug report.
585 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
587 * boolean.h (SCM_TRUE_P): Removed, as people might use it as a
588 replacement for !SCM_FALSEP.
590 * backtrace.c (display_error_body), boolean.h (SCM_BOOLP), gc.c
591 (scm_unhash_name), gh_data.c (gh_module_lookup), load.c
592 (scm_primitive_load), print.c (scm_simple_format), procs.c
593 (scm_procedure_documentation), procs.h (SCM_TOP_LEVEL), ramap.c

598 scm_array_set_x, scm_bit_set_star_x, scm_bit_count_star),
599 validate.h (SCM_VALIDATE_BOOL_COPY, SCM_VALIDATE_PROC): Replace
600 uses of SCM_TRUE_P (x) with SCM_EQ_P (x, SCM_BOOL_T).
602 2000-06-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
604 * eval.c (scm_badformalsp): New static function.
605 (SCM_CEVAL): Check arguments for procedure-with-setter closures.
606 (Thanks to Keisuke Nishida.)
608 The major reason for Guile's slow loading speed has been the fact
609 that a chain of Scheme level procedures has been evaluated for
610 every top-level symbol lookup during the first pass through the
613 The following is a kludge which I suggested four years ago, and
614 which I've repeatedly suggested since. Personally, I've never
615 been bothered by Guile's slow loading speed, so I thought I would
616 let someone else do it...
618 But since the new environments will be included first in
619 Guile-1.5, I thought it would make people happy to get the kludge
622 * modules.c: Added #include "libguile/vectors.h";
623 Added #include "libguile/hashtab.h";
624 Added #include "libguile/struct.h";
625 Added #include "libguile/variable.h";
626 Capture Scheme level `module-make-local-var!' to be used in the
627 standard eval closure.
628 (scm_standard_eval_closure): New primitive.
630 * modules.h (scm_standard_eval_closure): Declare.
632 * eval.c (scm_lookupcar): Test for !SCM_CONSP (SCM_CAR (env))
633 instead of SCM_TRUE (scm_procedurep (SCM_CAR (env))).
635 * symbols.c (scm_sym2vcell): Bypass dispatch in the evaluator for
636 standard eval closures.
638 * variable.c: Code layout fixes.
640 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
642 * Makefile.am: Added LIBS line to libpath which accidentally
643 disappeared in the change of 2000-06-01.
644 (Thanks to Dale P. Smith.)
646 2000-06-03 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
648 * scmsigs.c (scm_segfault): Removed. (Was probably added by
649 mistake since it is not mentioned in ChangeLog.)
651 * gc.h (SCM_VALIDATE_CELL): Cast result to (void) in order to
652 avoid compiler warnings in gcc. (Does this work for other
655 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
657 * gc.h (SCM_VALIDATE_CELL): Don't "use" the value returned by
659 (SCM_CARLOC, SCM_CDRLOC): Define directly instead of using
660 SCM_CELL_OBJECT_0 and SCM_CELL_OBJECT_1. It's not correct to take
661 the address of these expressions since they use SCM_VALIDATE_CELL.
662 (Thanks to Bernard Urban.)
664 * dynl.c: Changed #include <ltdl.h> --> #include
665 "libltdl/ltdl.h". (Thanks to Bill Schottstaedt.)
667 2000-06-01 Craig Brozefsky <craig@red-bean.com>
669 * Makefile.am: libguile_la_LDFLAGS gets -version-info args
670 from GUILE-VERSION definition of LIBGUILE version. Added to
671 libpath.h definitions for guileversion and libguileversion which
672 both get their values from GUILE-VERSION definition.
674 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
676 * numbers.h (SCM_BIGP): Don't use SCM_SMOB_PREDICATE in header
677 file: Code using numbers should not be required to include
680 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
682 * coop-threads.c.cygnus, coop-threads.h.cygnus, fsu-pthreads.h,
683 mit-pthreads.c, mit-pthreads.h: Deleted.
685 * Makefile.am (EXTRA_DIST), scmsigs.c, threads.[ch]: Drop
686 references to deleted files and fsu/mit thread support in
689 2000-05-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
691 * hooks.c (symbol_name, scm_create_hook): Restored the original
692 behaviour of scm_create_hook. Changing it was bad as Carl
693 R. Witty has pointed out.
695 * gc.c (scm_init_gc): We can still rely on scm_create_hook to
698 2000-05-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
700 * gc.c (scm_init_gc): Protect scm_after_gc_hook, since this will
701 soon not be done by scm_create_hook any longer.
703 * hooks.c (make_hook, print_hook, scm_create_hook,
704 scm_make_hook_with_name, scm_make_hook), hooks.h (SCM_HOOK_NAME,
705 SCM_HOOK_PROCEDURES, SCM_SET_HOOK_PROCEDURES,
706 scm_make_hook_with_name), init.c (scm_boot_guile_1): Hooks no
707 longer have names. As an intermediate solution, the name
708 predicate is emulated via object properties, but use of this
709 feature is deprecated.
711 * hooks.h (scm_free_hook): Removed, as it is never defined.
713 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
715 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_FIXABLE):
716 Un-deprecated since otherwise user code can't determine whether a
717 number fits into an inum any longer. The names should be changed
720 * numbers.c (scm_big2inum): Eliminated use of SCM_UNEGFIXABLE.
722 * tags.h (SCM_UNPACK_CAR): Deprecated.
724 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
726 * filesys.h (SCM_OPDIRP), fluids.h (SCM_FLUIDP, SCM_FLUID_NUM),
727 fports.h (SCM_OPFPORTP, SCM_OPINFPORTP, SCM_OPOUTFPORTP), hooks.h
728 (SCM_HOOK_ARITY), keywords.h (SCM_KEYWORDP, SCM_KEYWORDSYM),
729 numbers.h (SCM_NUMP, SCM_BIGSIGN, SCM_BDIGITS, SCM_NUMDIGS):
730 Replace SCM_UNPACK_CAR appropriately. Don't access cells via
731 SCM_{SET}?C[AD]R unless they are known to be cons cells.
733 * gc.c (scm_heap_seg_data_t, scm_mark_locations, scm_cellp,
734 init_heap_seg): Remove unused struct member variable 'valid'.
736 2000-05-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
738 * fports.c (fport_write), ports.c (scm_markstream, scm_port_mode,
739 scm_print_port_mode), ports.h (SCM_OPPORTP, SCM_OPINPORTP,
740 SCM_OPOUTPORTP, SCM_INPUT_PORT_P, SCM_OUTPUT_PORT_P, SCM_OPENP),
741 procs.h (SCM_CLOSCAR), unif.h (SCM_ARRAY_NDIM, SCM_ARRAY_CONTP),
742 variable.h (SCM_VARIABLEP): Replace SCM_UNPACK_CAR
745 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
747 * gc.c (free_list_length), hash.c (scm_hasher), macros.c
748 (scm_macro_type), objects.c (scm_class_of), options.c
749 (scm_options), print.c (scm_iprin1), strports.c (st_seek), throw.c
750 (SCM_LAZY_CATCH_P): Replace SCM_UNPACK_CAR appropriately.
752 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
754 * eval.c (scm_macroexp, SCM_CEVAL, scm_force), tags.h: Replace
755 SCM_UNPACK_CAR with SCM_CELL_TYPE or SCM_CELL_WORD_0.
757 * eval.c (scm_force): Add documentation.
759 * eval.c (scm_force, scm_cons_source): Don't access cells via
760 SCM_{SET}?C[AD]R unless they are known to be cons cells.
762 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
764 * strings.h (SCM_NSTRINGP, SCM_NRWSTRINGP), tags.h
765 (SCM_NDOUBLE_CELLP), vectors.h (SCM_NVECTORP): Deprecated.
767 * gc.c (scm_igc), gc.h (SCM_PTR_MASK, SCM_PTR_LT): Removed #ifdef
768 nosve #endif conditionally compiled code.
770 2000-05-23 Michael Livshin <mlivshin@bigfoot.com>
772 * gc.c (scm_heap_seg_data_t): fixed comment for the `span' member.
774 2000-05-22 Michael Livshin <mlivshin@bigfoot.com>
776 * guile-doc-snarf.in: put the preprocessed file through sed to
777 trim all lines to 1024 chars. I hope it doesn't break anybody's
778 sed. we'll see. (note: this is lossy trimming, i.e. the spill
779 isn't wrapped around but actually chopped off. this seemed to me
780 safe because the current snarfer doesn't understand multi-line
781 cookies anyway. in the long term, it would be nice not to depend
782 on AWK for anything.)
784 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): reverted
785 the previous change to this macros, after deciding to torture the
788 2000-05-21 Michael Livshin <mlivshin@bigfoot.com>
790 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): brought
791 the yucky, ugly and nasty conditional compilation back. sorry,
792 but it was either that or requiring GAWK to build Guile.
793 (lots of places): removed the code that implemented the old GC
796 * init.c (scm_boot_guile_1): removed the code conditioned on
797 !GUILE_NEW_GC_SCHEME.
799 * __scm.h: (GUILE_NEW_GC_SCHEME): removed.
801 * gc.c (scm_protect_object, scm_unprotect_object): change the
802 implementation to more efficient (at least in the time complexity
803 sense). the calls should now also be thread-safe -- I suspect
804 that people expect them to be. (thanks to Han-Wen Nienhuys)
805 (lots of places): removed the code that implemented the old GC
808 * hashtab.c (scm_hash_fn_create_handle_x): add missing
809 SCM_REALLOW_INTS before return. I really wonder about the
810 possible interactions between hashtables, threads & GC. it
811 doesn't look healthy at all.
813 2000-05-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
815 * unif.c (scm_bit_count): Fixed the parameter checks. Thanks to
818 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
820 * __scm.h (SCM_DEBUG_CELL_ACCESSES), gc.h (SCM_): Added as a new
821 debug option to verify all accesses to cells actually access
824 * gc.h (SCM_VALIDATE_CELL): Added. Only performs validation if
825 SCM_DEBUG_CELL_ACCESSES is set to 1.
827 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
828 SCM_SET_CELL_OBJECT): Use SCM_VALIDATE_CELL to check every cell
831 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
833 * gh_data.c (gh_scm2chars, gh_scm2shorts, gh_scm2longs,
834 gh_scm2floats, gh_scm2doubles): Change !SCM_NIMP to SCM_IMP.
836 * gc.c (scm_cellp): Fixed and simplified.
838 * throw.c (JBJMPBUF, SETJBJMPBUF, SCM_JBDFRAME, SCM_SETJBDFRAME,
839 make_jmpbuf, scm_init_throw): Now using double cells to represent
840 jump buffers when using debug extensions.
844 2000-05-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
846 * gh.h gh_data.c gh_funcs.c (gh_new_procedure*, gh_chars2byvect,
847 gh_shorts2svect, gh_longs2ivect, gh_ulongs2uvect, gh_floats2fvect,
848 gh_doubles2dvect, gh_doubles2scm, gh_define, gh_lookup,
849 gh_module_lookup): Accept const pointers as parameters.
851 * gh.h gh_data.c (gh_int2scmb): Deprecated.
853 2000-05-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
855 * __scm.h (SCM_DEBUG_REST_ARGUMENT): Renamed from
856 SCM_DEBUG_REST_ARGUMENTS in order to clarify that we don't test
857 the actual arguments in the list, but rather the rest argument as
860 * validate.h (SCM_VALIDATE_REST_ARGUMENT): Added.
862 * async.c (scm_noop), eval.c (scm_map, scm_for_each), list.c
863 (scm_list_star, scm_append, scm_append_x), ports.c
864 (scm_close_all_ports_except), ramap.c (scm_array_map_x,

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

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

954 scm_newsmob), tag.c (scm_tag), tag.h (scm_tag), tags.h
955 (scm_tc16_flo, scm_tc_flo, scm_tc_dblr, scm_tc_dblc): Wrapped
956 deprecated code between #if (SCM_DEBUG_DEPRECATED == 0) #endif.
958 * fports.c (scm_fport_buffer_add), ports.c (scm_input_port_p,
959 scm_output_port_p), print.c (scm_get_print_state), validate.h
960 (SCM_VALIDATE_CHAR): Replace use of deprecated macros
961 SCM_INPORTP, SCM_OUTPORTP, SCM_ICHRP by SCM_INPUT_PORT_P,
962 SCM_OUTPUT_PORT_P, SCM_CHARP, respectively.
964 2000-05-14 Gary Houston <ghouston@arglist.com>
966 * stime.c (scm_strftime): if HAVE_TM_ZONE is not defined, hack the
967 TZ environment variable so that the %Z format returns the zone
968 from the input vector instead of the system default.
970 from Keisuke Nishida:
971 * fports.c (scm_setvbuf): minor docstring fix.
972 * ports.h (scm_generic_fgets): obsolete prototype deleted.
974 2000-05-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
976 * __scm.h: Added new section for debugging options.
978 (SCM_DEBUG_DEPRECATED): If 1, no deprecated code is included to
979 help developers to get rid of references to deprecated code.
981 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_UNEGFIXABLE,
982 SCM_FIXABLE, SCM_FLOBUFLEN): These macros are no longer provided
983 as part of the interface and are marked as deprecated in the
986 * numbers.c (scm_make_real, scm_make_complex): Inlined the
987 corresponding macros SCM_NEWREAL and SCM_NEWCOMPLEX,
990 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX, SCM_INEXP, SCM_CPLXP,
991 SCM_REAL, SCM_IMAG, SCM_REALPART, scm_makdbl, SCM_SINGP,
992 SCM_NO_BIGDIG, SCM_NUM2DBL, scm_dblproc): Deprecated.
994 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
996 * gc.h (scm_cell, SCM_CELL_WORD, SCM_CELL_OBJECT,
997 SCM_SET_CELL_WORD, SCM_SET_CELL_OBJECT): Scheme cells now consist
998 of two scm_bits_t values instead of two SCM values, because it is
999 legal for cell entries to hold values that are not scheme objects.
1001 (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR):
1002 Use SCM_SETC[AD]R to modify contents of pairs.

1006 * numbers.c (IS_INF, isfinite): Added FIXME comment.
1008 (scm_abs, scm_magnitude): Make these two independent of each
1009 other. scm_abs now reports an error if given a complex argument.
1011 (scm_istr2flo, scm_integer_p). Use SCM_REAL_VALUE instead of
1012 SCM_REALPART if the object is known to be real.
1014 (scm_init_numbers): No need to use SCM_NEWREAL macro for speed
1017 * numbers.h (SCM_SINGP): Set to 0 instead of SCM_BOOL_F.
1019 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>

1025 gh_scm2doubles), hash.c (scm_hasher), ramap.c (scm_array_fill_int,
1026 ramap_rp, scm_array_map_x), random.c (vector_scale,
1027 vector_sum_squares), unif.c (scm_make_uve, scm_array_p,
1028 scm_array_set_x): Use SCM_REAL_VALUE instead of SCM_REALPART if
1029 the object is known to be real. Use SCM_COMPLEXP instead of
1030 deprecated SCM_CPLXP. Use SCM_INEXACTP instead of deprecated
1033 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1035 * numbers.c: No need to include unif.h.
1037 (IS_INF): Returned to old test for now: x == x + 1 will not work
1038 for large numbers due to rounding errors.
1039 Thanks to Kalle Olavi Niemitalo.
1041 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
1043 * numbers.c (scm_divbigdig): Removed outdated comment.
1045 (scm_number_to_string, scm_string_to_number, scm_number_p,
1046 scm_real_p, scm_integer_p, scm_inexact_p, scm_gr_p, scm_leq_p,
1047 scm_geq_p, scm_make_rectangular, scm_make_polar,
1048 scm_inexact_to_exact): Added comments.
1050 (add1, scm_init_numbers): Removed add1.
1052 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
1054 * numbers.c (IS_INF): The new test is x == x + 1. The old test
1055 x == x/2 did not work for zero values. Thanks to Han-Wen Nienhuys
1058 (scm_number_to_string, scm_sum, scm_difference, scm_two_doubles,
1059 scm_num2long, scm_num2long_long, scm_num2ulong): Reordered
1062 2000-05-09 Marius Vollmer <mvo@zagadka.ping.de>
1064 * scmsigs.c (take_signal): Execute SCM_ASYNC_TICK for SIGSEGV,
1065 SIGILL and SIGBUS signals. These signals are not continuable and
1066 must be handled for real right away.
1068 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1070 * numbers.c (scm_zero_p, scm_positive_p, scm_negative_p,

1072 scm_inexact_to_exact): Reordered dispatch sequence.
1074 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1076 * feature.c: No need to include "libguile/smob.h"
1078 (scm_loc_features, features, scm_add_feature, scm_init_feature):
1079 Removed variable 'scm_loc_features' as a pointer to the SCM value
1080 holding the features list. Using variable 'features' instead,
1081 which holds the interned pair. Thus, SCM_SETCDR can be used
1082 instead of pointer trickery.
1084 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1086 * alist.c (scm_acons): Use SCM{_SET}?_CELL_OBJECT as long as a
1087 cell is not known to be a valid pair.
1089 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1091 * eval.c (ASRTSYNTAX, scm_m_body, scm_m_letrec1): Removed
1092 ASRTSYNTAX. Using SCM_ASSYNT instead.

1098 (bodycheck): Removed.
1100 * stacks.c (stack_depth, read_frame, read_frames): Removed
1101 redundant calculation of size, minimized some variable scopes.
1103 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1105 * pairs.c (scm_cons, scm_cons2): Use SCM{_SET}?_CELL_OBJECT as
1106 long as a cell is not known to be a valid pair.
1108 (scm_pair_p): Eliminated redundant SCM_IMP test.
1110 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1112 * eval.c (scm_m_body, scm_macroexp, unmemocopy, scm_eval_args,
1113 scm_deval_args): Eliminated redundant SCM_IMP tests.
1115 * hashtab.c (scm_ihashx, scm_sloppy_assx, scm_delx_x), weaks.c
1116 (scm_make_weak_key_hash_table, scm_make_weak_value_hash_table,
1117 scm_make_doubly_weak_hash_table): Fixed critical sections.
1118 Thanks to Keisuke Nishida.
1120 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1122 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest):
1123 Fixed some goto-related initialization bugs (introduced by me).
1125 2000-05-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
1127 * numbers.h (SCM_INUM0): Uses SCM_MAKINUM instead of SCM_PACK.
1129 * dynl.c (dynl_obj, DYNL_OBJ, get_dynl_obj): Removed.
1131 (DYNL_FILENAME, DYNL_HANDLE): Use SCM_CELL... macros instead of
1134 (SET_DYNL_HANDLE): Added.
1136 (scm_dynamic_object_p): Simplified.
1138 (scm_dynamic_unlink, scm_dynamic_func): Changed comment. Deliver
1139 better error message when accessing unlinked dynamic objects.
1140 Eliminated call to get_dynl_obj.
1142 2000-05-03 Marius Vollmer <mvo@zagadka.ping.de>
1144 * scmsigs.c (orig_handlers) [!HAVE_SIGACTION]: Fix declaration to
1145 be an array of function pointers instead of being a pointer to an
1146 array returning function. Thanks to Kalle Olavi Niemitalo!
1148 2000-05-03 Dirk Herrmann <D.Herrmann@tu-bs.de>
1150 * numbers.c (scm_divbigbig, scm_divbigint), numbers.h
1151 (scm_divbigbig, scm_divbigint): Don't return zero any more to
1152 indicate that a division has a remainder, return SCM_UNDEFINED
1153 instead. It is improbable that anyone actually used these
1154 functions outside of numbers.c. For this reason and due to the
1155 change in behaviour the functions are static now. Thus, if
1156 surprisingly there are users of these functions they will at least
1159 * numbers.c: Removed #ifdef SCM_BIGDIG #endif in those functions,
1160 that already have a clean dispatch order. Note: SCM_BIGDIG is
1163 * numbers.c (scm_inexact_p): Simplified.
1165 * numbers.c (scm_num_eq_p, scm_less_p, scm_max, scm_min,
1166 scm_product, scm_num2dbl, scm_angle): Reordered dispatch
1167 sequence, thereby fixing some comparisons of SCM values with
1170 * numbers.c (scm_divide): Division by zero of inums leads to an
1171 error now. (Formerly, an infinite number was returned.)
1173 Respect the fact, that scm_divbigbig does now return SCM_UNDEFINED
1174 if a division has a remainder.
1176 2000-05-02 Gary Houston <ghouston@arglist.com>
1178 * Makefile.am (INCLUDES): add ${INCLTDL} (thanks to Tim Mooney).
1180 2000-05-02 Dirk Herrmann <D.Herrmann@tu-bs.de>
1182 * numbers.c (scm_logtest, scm_division): Reordered dispatch
1183 sequence, thereby fixing some comparisons of SCM values with

1198 call to scm_makdbl with a call to scm_make_real or
1199 scm_make_complex, depending on whether the imaginary part is known
1202 2000-05-01 Gary Houston <ghouston@arglist.com>
1204 * scmsigs.c: fix the definition of orig_handlers for the case
1205 that HAVE_SIGACTION is not defined (thanks to
1206 Kalle Olavi Niemitalo).
1208 * Makefile.am: remove include_HEADERS (was libguile.h)
1209 libguile.h: moved to top level directory.
1211 2000-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1213 * numbers.c (SCM_SWAP): Moved to the top of the file to allow for
1216 * numbers.c (scm_modulo, scm_gcd, scm_lcm, scm_logand, scm_logior,

1227 occur anywhere else throughout guile.
1229 * numbers.c (scm_quotient): Fixed parameter number in error
1232 * numbers.c (scm_remainder): Reordered dispatch sequence.
1234 2000-04-25 Gary Houston <ghouston@arglist.com>

1249 * procs.c (scm_init_iprocs), procs.h (scm_subr, scm_iproc,
1250 scm_dsubr, scm_init_iprocs): Removed.
1252 * procs.h (SCM_SUBRF, SCM_DSUBRF): Access the cell words
1253 directly instead of casting a cell to a C struct.
1255 2000-04-22 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1257 Better modularization of GC extensions through new C level GC
1260 * weaks.c (scm_weaks_prehistory): New function: Add

1315 the root build directory.
1317 * numbers.c (scm_odd_p, scm_even_p): Use SCM_WRONG_TYPE_ARG
1318 instead of SCM_ASSERT (0, ...). (Some compilers will complain

1339 scm_quotient): Reordered dispatch sequence to first handle
1340 immediates, second handle bignums and finally handle generic
1341 functions respectively signal wrong type arguments. Hopefully
1342 this will allow for easier separation when goops is integrated.
1344 2000-04-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
1346 * gc.c (which_seg): Use SCM2PTR to convert a non immediate SCM

1603 * __scm.h (SCM_WTA_DISPATCH_[012n]): To test whether a SCM value
1604 contains a raw zero value it has to be unpacked.
1606 * debug.c (with_traps_inner, scm_with_traps): Passing SCM values
1607 via void * requires unpacking / packing.

1623 * async.[ch]: unexpose low-level async access macros (thanks to
1626 * validate.h: move async validation macros to async.c (nobody else
1627 needs them anyway), and rename them.
1629 2000-04-04 Michael Livshin <mlivshin@bigfoot.com>
1631 * async.h: kill the scm_async_t struct. having a heap cell
1632 pretending to be a C struct is not helthy, and is not needed here
1633 anyway, as asyncs happily fit in one heap cell.
1635 * async.c: reflect the fact that asyncs are now represented by
1636 single heap cell each.
1638 2000-04-04 Gary Houston <ghouston@arglist.com>

1700 2000-04-03 Michael Livshin <mlivshin@bigfoot.com>
1702 * guardians.c (scm_guardian_zombify): mark all zombies in a
1703 separate loop after processing all the currently known live
1704 guardians, so as to not introduce order dependencies (thanks to
1705 Gary Houston). note that the order problems are still there if
1706 some guardians are themselves zombies, but that's a sick case that
1707 I'm not going to worry about.
1708 also, make another outer loop to process zombified
1709 guardians (which are uncovered while marking zombies).

1856 (mother): New function.
1857 (coop_create): New thread spawning mechanism which uses a "mother

2038 SCM_SET_CELL_OBJECT, SCM_SET_CELL_OBJECT_[0-3], SCM_CELL_TYPE,
2039 SCM_SET_CELL_TYPE): Added a set of low level macros for accessing
2041 (SCM_CELL_WORD_[0-3]): Renamed from the SCM_CELL_WORD[0-3].
2043 * procs.h, procs.c: Instead of SCM_{SET_}?CELL_WORD[12], use the
2044 newly introduced SCM_{SET_}?CELL_OBJECT_[12] macros.
2046 2000-03-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2048 * tags.h: Disabled definition of SCM_VOIDP_TEST.
2050 Defining SCM as void * introduces problems which haven't been
2051 handled yet. Developers who work with these issues can enable it
2052 in their working copies.
2054 Disabling this definition exposes a set of newly introduced and
2055 older misuses of types which causes warning messages during
2056 compilation. We'll fix this successively.
2058 * gc.c (scm_mark_locations): Changed * (SCM **) X --> * (SCM *) X
2059 in order to obtain a value of type SCM.
2060 (scm_cellp): Updated with new changes to scm_mark_locations.
2062 * continuations.h (SCM_SETJMPBUF): Cast second arg into SCM.
2064 * continuations.c (scm_make_cont): Removed cast of size_t into
2067 * symbols.h (SCM_SETCHARS): Cast second arg into SCM.
2069 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
2071 * numbers.h (SCM_SETNUMDIGS): Use SCM_BIGSIZEFIELD macro for
2072 shifting, not constant. Thanks to Dale P. Smith.
2074 * numbers.c (scm_sum, scm_difference): Don't test a SCM value
2075 for being less than zero. Decode it to a C value first. Again,
2078 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
2080 * numbers.h, ramap.c, struct.h, vectors.h: Don't use SCM2PTR for
2081 non scheme values. If raw data is stored in SCM variables, it has
2082 to be accessed using SCM_UNPACK until a better solution is found.
2084 2000-03-22 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2086 * tags.h (SCM_ECONSP, SCM_NECONSP): More corrections of
2087 pointer-arithmetic induced by the SCM_PACK/UNPACK change.
2089 * print.c (scm_iprin1): SCM_PACK/UNPACK corrections.
2091 * gc.c (scm_gc_sweep): SCM_PACK/UNPACK corrections.
2093 * eval.c (SCM_CEVAL, scm_unmemocar): SCM_PACK/UNPACK corrections.
2095 * dynwind.c (scm_swap_bindings): SCM_PACK/UNPACK corrections.
2097 * async.c, __scm.h: Removed lots of the old async click logic. It
2098 is possible to reinsert it by defining GUILE_OLD_ASYNC_CLICK in
2099 __scm.h. Let's try this out and dump the old code after the
2100 threads reorganization.
2101 (set-tick-rate, set-switch-rate): Conditionally removed.
2103 2000-03-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2105 * gc.c (scm_gc_mark): Bugfix 1: The recent SCM_PACK/UNPACK change
2106 made SCM values into pointers. This turned an arithmetic
2107 computation of the address of the vcell into a pointer-arithmetic
2108 one, thereby screwing up marking of structs.
2109 Bugfix 2: Removed incompletely introduced loop variable `j' used
2110 when protecting the tail array of a struct.
2112 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2114 * struct.h (SCM_STRUCT_DATA): Don't cast SCM values to pointers.
2116 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2118 * symbols.h, symbols.c (scm_strhash): Declare the string
2119 parameter as constant, since it is not modified.
2121 * symbols.c (scm_intern_obarray_soft,
2122 scm_sysintern0_no_module_lookup): Can now pass constant strings
2123 to scm_strhash without need for casting.
2125 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2127 * vectors.h (SCM_VELTS, SCM_VELTS_AS_STACKITEMS): Don't cast SCM
2128 values to pointers. Use SCM2PTR instead.
2130 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2132 * async.c (scm_set_tick_rate, scm_set_switch_rate): Don't unpack
2133 results of SCM_INUM.
2135 2000-03-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2137 * init.c (scm_boot_guile_1): Renamed GUILE_GC_TRIGGER_1 -->
2138 GUILE_MIN_YIELD_1, GUILE_GC_TRIGGER_2 --> GUILE_MIN_YIELD_2.
2139 GUILE_MIN_YIELD_X now take *positive* fractions of heap size.
2141 * gc.c, gc.h (SCM_MIN_YIELD_1, SCM_MIN_YIELD_2,
2142 min_yield_fraction, min_yield, adjust_min_yield): Renamed from
2143 SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2, gc_trigger_fraction,
2144 gc_trigger, adjust_gc_trigger.
2146 * gc.c (alloc_some_heap): Further improvement of minimal heap size
2148 (SCM_MAX): New macro.
2149 (scm_freelist_t): New field: collected_1. Previous amount of
2151 (gc_sweep_freelist_finish): Trigger based on two last values of
2152 freelist->collected to avoid unnecessary allocation due to
2154 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2):
2155 Adjusted to 45000 cells, 40% and 40%. Gives quick startup
2156 without extra heap allocation.
2158 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2160 * numbers.h (SCM_MAKINUM): The parameter to SCM_MAKINUM should
2161 already be a C value. No need to unpack it.
2163 * numbers.c (scm_long_long2num): Cast the parameter to scm_bits_t
2164 if we know it fits into an inum.
2166 * ramap.c (ramap_rp): An scm_tc7_[ui]vect object does point to a
2167 field of long values. In contrast, SCM_VELTS accesses a field of
2170 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2172 * gc.c (scm_gc_stats): Inserted explanation of local_scm_mtrigger
2174 (scm_gc_yield_1): New variable: Holds previous yield. Used to
2175 make better judgements.
2176 (gc_sweep_freelist_finish): Inserted explanation of use of
2179 * print.h, stacks.h, options.c, options.h: Changed C++
2182 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2184 * tags.h (SCM2PTR, PTR2SCM): Use SCM_PACK / SCM_UNPACK correctly.
2186 * numbers.h (SCM_INUMP, SCM_MAKINUM, SCM_INUM0, SCM_COMPLEX_REAL,
2187 SCM_COMPLEX_IMAG, SCM_NUMP, SCM_BDIGITS): Use SCM_PACK /
2188 SCM_UNPACK / SCM2PTR correctly.
2190 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2192 * gc.c (adjust_gc_trigger): Improved documentation.
2193 (alloc_some_heap): Since gc_trigger is used against
2194 freelist->collected, this is the value which should be used to
2195 predict minimum growth.
2197 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2199 * eval.h: Fix mixup of packed/unpacked SCM values. (Thanks
2200 Thien-Thi Nguyen for the patch.)
2202 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2204 * numbers.c (scm_ash): Fixed typing problems with the second
2205 parameter and added some documentation. (Thanks Thien-Thi Nguyen
2206 for indicating the problem.)
2208 2000-03-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2210 * gc.c, gc.h (scm_gc_yield): New variable.
2211 (adjust_gc_trigger): Use scm_gc_yield.
2212 (alloc_some_heap): Use scm_gc_yield instead of
2213 scm_gc_cells_collected.
2215 * coop-threads.c: Addd #include "root.h", #include "strings.h".
2217 * debug.c: Added #include "root.h". (Thanks to Thien-Thi Nguyen.)
2219 * gc.c (scm_gc_for_newcell, adjust_gc_trigger): Improved GC
2220 trigger adjustmeant: Take yield (freed cells) for all freelists
2222 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Tuned
2223 to 50000 cell heap with 45% trigger.
2224 (scm_gc_cells_collected): Reintroduced.
2225 (SCM_HEAP_SIZE): New macro.
2226 (scm_gc_sweep): Reintroduced correct computation of
2227 scm_cells_allocated.
2228 (scm_freelist_t): Corrected commentary for field `cluster_size':
2229 Clustersize counts objects, not cells; New member
2230 `clusters_allocated'.
2232 2000-03-19 Michael Livshin <mlivshin@bigfoot.com>
2234 * *.[hc]: add Emacs magic at the end of file, to ensure GNU
2237 2000-03-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2239 * threads.h: Added #include "libguile/throw.h". (Thanks to
2242 2000-03-18 Michael Livshin <mlivshin@bigfoot.com>
2244 * tags.h: (SCM_DOUBLE_CELLP, SCM_NDOUBLE_CELLP): new macros (bad
2245 names, anyone got any better ones?)
2247 * gc.h: (typedef struct scm_freelist_t) remove from here.
2249 * gc.c: (CELL_UP, CELL_DN) made these macros take additional
2250 parameter (the span).
2251 (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK) new macros.
2252 (typedef struct scm_freelist_t) moved here from gc.h, it had no
2253 business being externally visible.
2254 (typedef struct scm_heap_seg_data_t) renamed from
2255 scm_heap_seg_data, to be style-compliant.
2256 (scm_mark_locations) if the possible pointer points to a
2257 double-cell, check that it's properly aligned.
2258 (init_heap_seg) align double-cells properly, work with the
2259 assumption that the segment size divides cleanly by cluster size.
2260 (round_to_cluster_size) new function.
2261 (alloc_some_heap, make_initial_segment) use round_to_cluster_size
2262 to satisfy the new init_heap_seg invariant.
2264 2000-03-18 Dirk Herrmann <D.Herrmann@tu-bs.de>

2321 2000-03-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2323 * gc.c, gc.h: Cleanup of the change of 2000-03-15.
2324 Cluster sizes are now independent of GC trigger values.
2325 GUILE_GC_TRIGGER_n can now specify a relative trigger value:
2326 A negative integer gives fraction of total heap size in percent.
2327 (SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Default values set to -40.
2329 * init.c (scm_boot_guile_1): Introduced new variable
2330 GUILE_MAX_SEGMENT_SIZE; New environment variable names:
2331 GUILE_INIT_SEGMENT_SIZE_1, GUILE_GC_TRIGGER_1,
2332 GUILE_INIT_SEGMENT_SIZE_2, GUILE_GC_TRIGGER_2
2334 2000-03-16 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2336 * __scm.h (GC_FREE_SEGMENTS): Disable this until we have made
2337 freeing of segment work with the new GC scheme. (Thanks to
2338 Michael Livshin.) Oops, also happened to make GUILE_NEW_GC_SCHEME
2339 the default, but I'll let this change stay in CVS Guile since this
2340 code is not expected to contain serious bugs.
2342 2000-03-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2344 * gc.c, gc.h (scm_map_free_list): Define also if GUILE_DEBUG is
2346 (scm_free_list_length): New procedure (GUILE_DEBUG).
2347 Fixed a small but serious bug introduced by the previous change.
2349 * gc.c (scm_gc_sweep): Moved variable n_objects to inner sweep
2350 loop and declare as register.
2352 * gc.c (scm_gc_sweep): Sigh... forgot to clear private freelists
2355 Wed Mar 15 08:27:04 2000 Greg J. Badros <gjb@cs.washington.edu>
2357 * fluids.c: Docstring patch from Keisuke Nishida. Some
2358 reindentation, too, and a couple formals renamed. Should
2359 fluid-set! return UNSPECIFIED instead of a value?
2361 Wed Mar 15 08:24:58 2000 Greg J. Badros <gjb@cs.washington.edu>
2363 * Makefile.am: Separate out DOT_X_FILES and DOT_DOC_FILES, and
2364 generate the latter from the concrete listing of the former. Then
2365 make guile-procedures.txt depend on DOT_DOC_FILES instead of
2366 *.doc, so that rebuilding it works.
2368 Wed Mar 15 08:12:14 2000 Greg J. Badros <gjb@cs.washington.edu>
2370 * libguile.h: Include libguile/validate.h. Thanks Keisuke Nishida!
2372 * guile-snarf.awk.in: Replace docstring line-ending \n" and \n\n"
2373 with nothing and \n, respectively. Thanks Keisuke Nishida for
2374 noticing this problem.
2376 2000-03-15 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2378 * __scm.h (GUILE_NEW_GC_SCHEME): Define this if you want to test a
2379 new way of allocating heap. It makes Guile fast, but still
2382 * gc.c, gc.h, pairs.h, init.c: Implementation of a new way of
2383 allocating heap. The basic idea is to trigger GC every Nth
2384 allocated cell and grow heap when free list runs out. The scheme
2385 has been extended so that GC isn't triggered until all remaining
2386 cells are used. The implementation is also prepared for
2387 development in the direction of POSIX threads.
2389 * gc.c (SCM_EXPHEAP): In order to grow by a factor of 1.5,
2390 SCM_EXPHEAP should return half of the heap size.
2392 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2394 The following change to init.c is only enabled if Guile was
2395 configured with --enable-guile-debug.
2397 * init.c (scm_i_getenv_int): New function.
2398 (scm_boot_guile_1): Use the environment variables
2399 GUILE_INIT_HEAP_SIZE, GUILE_INIT_HEAP_SIZE2 to select heap size if
2400 they exist. (This may be replaced by a Scheme level mechanism in
2403 * objprop.c (s_scm_set_object_property_x): Use scm_assq instead of
2404 scm_assoc. (Thanks to Keisuke Nishida.)
2406 2000-03-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2408 * eval.c, lang.c, lang.h (scm_lisp_nil, scm_lisp_t): Renamed from
2409 scm_nil, scm_t. (Thanks to Keisuke Nishida.)
2411 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2413 * init.c (scm_boot_guile_1): Use same initial segment size for
2414 1-word and 2-word segments. Having the smaller size causes Guile
2415 to GC too often. Obviously something needs to be done to allow
2416 for a smaller 2-word segment without this to happen. (The amount
2417 of heap for each type should be automatically adapted to the
2418 application somehow.)
2420 [Almost all of these changes should be documented in the NEWS
2423 * gc.h (scm_freelist_t): New type.
2425 * pairs.h (SCM_NEWCELL, SCM_NEWCELL2): Use new style freelists.
2427 * gc.c (SCM_INIT_HEAP_SIZE): Changed from 32768 --> 40000 so that
2428 all of Guile basics fits into one segment and there suitable room
2430 (SCM_EXPHEAP): Now takes an argument. Grow by a factor of 1.5
2432 (scm_freelist, scm_freelist2): Now of type scm_freelist_t.
2433 Freelists now contains information about object span, cells
2434 collected and amount of cells in heap segments belonging to the
2436 (scm_heap_size, scm_gc_cells_collected): Removed.
2438 * init.c (scm_boot_guile_1): Make 2-word segment 8K (512 cells).
2440 * Makefile.am (libguile_la_LDFLAGS): Bumped library version
2443 * __scm.h eq.c, eval.c, gc.c, gc.h, gh_data, hash.c, numbers.c,
2444 numbers.h, objects.c, ramap.c, random.c, unif.c, unif.h: Extensive
2445 rewrite of handling of real and complex numbers.
2446 (SCM_FLOATS, SCM_SINGLES): These #ifdef conditionals have been
2447 removed along with the support for floats. (Float vectors are
2450 * tags.h (scm_tcs_bignums): Removed.
2451 (scm_tc16_bigpos, scm_tc16_bigneg): Replaced by scm_tc16_big.
2452 Use SCM_BIGSIGN(x) to test for sign!
2453 (scm_tc16_big): The new bignum type.
2454 (SCM_REAL_PART, SCM_IMAG_PART): Removed.
2456 * numbers.h (SCM_BIGSIGN): Sign moved to bit 16.
2457 (scm_makdbl): Deprecated.
2458 (SCM_NEWREAL, SCM_NEWCOMPLEX): New macros.
2459 (SCM_SINGP): Deprecated.
2461 (SCM_INEXP, SCM_CPLXP): Deprecated.
2462 (SCM_INEXACTP, SCM_COMPLEXP): New macros.
2463 (SCM_COMPLEX_REAL, SCM_COMPLEX_IMAG): Renamed from
2464 SCM_REAL, SCM_IMAG (and now only valid for complex numbers).
2465 (SCM_REAL, SCM_IMAG): New, *deprecated*, selectors which work both
2466 for doubles and complex numbers.
2467 (SCM_REAL_VALUE): New selector for doubles.
2468 (scm_double_t, scm_complex_t): New types.
2471 * numbers.c (scm_floprint, scm_floequal): Removed.
2472 (scm_print_real, scm_print_complex, scm_real_equalp,
2473 scm_complex_equalp): New functions.
2475 * unif.c (scm_makflo): Removed.
2477 * smob.h (SCM_SMOB_PREDICATE): New macro.
2478 (SCM_NEWSMOB2, SCM_RETURN_NEWSMOB2, SCM_NEWSMOB3,
2479 SCM_RETURN_NEWSMOB3): New macros.
2481 1999-11-21 Michael Livshin <mlivshin@bigfoot.com>
2483 The following changes implement primitive support for double cells
2484 (i.e. four-word cells) and change the representation of some
2485 things to multi-cells instead of cons+malloc. (Applied and
2488 * pairs.h (SCM_NEWCELL2): double-cell variants of SCM_NEWCELL.
2489 (SCM_CELL_WORD, SCM_CELL_WORDLOC, SCM_SET_CELL_WORD): primitive
2490 multi-cell access macros (used by the ones below).
2491 (SCM_CELL_WORD[0-3], SCM_SET_CELL_WORD[0-3]): multi-cell access
2494 * gc.c (scm_freelist2): multi-cell freelists.
2495 (inner_map_free_list): map_free_list, parameterized on ncells.
2496 "nn cells in segment mm" was misleading for ncells > 1; changed to
2497 "objects". still print cells too, though.
2498 (scm_map_free_list): rewritten using inner_map_free_list.
2499 (scm_check_freelist): get freelist as parameter, since now we have
2501 (scm_debug_newcell2): multi-cell variants of
2503 (scm_gc_for_newcell): take ncells and freelist pointer as
2505 (scm_gc_mark): add case for tc7_pws (procedures with setters are
2507 (scm_gc_sweep): don't free the float data, since it's not malloced
2509 (init_heap_seg): didn't understand what n_new_objects stood for,
2510 so changed to n_new_cells.
2511 (make_initial_segment): new function, makes an initial segment
2512 according to given ncells.
2513 (scm_init_storage): call make_initial_segment, for ncells={1,2,3}.
2515 * numbers.c (scm_makdbl): no malloc'ing needed, so the
2516 {DEFER,ALLOW}_INTS thing removed.
2518 * numbers.h (struct scm_dbl): changed to represent a double cell,
2519 with the number in the second half.
2521 * dynwind.c: changed the wind-guards representation to double
2524 * procs.c, procs.h: changed the procedure-with-setter representation
2527 * async.c, async.h: made async representation a double cell.
2529 * dynl.c: made dynamic_obj representation a double cell.
2531 2000-03-13 Gary Houston <ghouston@arglist.com>
2533 * ports.c (flush_void_port): renamed to flush_port_default.
2534 (end_input_void_port): renamed to end_input_default.
2536 * init.c (scm_standard_stream_to_port): create a void port instead
2537 of opening /dev/null if the standard file descriptors are bad.
2538 advantages: no portability problems, doesn't waste a file descriptor,
2539 simplifies the code (thanks to Marius for the idea).
2541 * vports.c (s_scm_make_soft_port): call scm_port_non_buffer.
2543 * void ports: make reading from a void port give EOF instead of
2545 * ports.c (s_scm_sys_make_void_port): modified docstring.
2546 (fill_input_void_port): new proc.
2547 (scm_init_ports): set up fill_input_void_port.
2548 * ports.c (scm_port_non_buffer): new proc.
2549 (scm_void_port): call scm_port_non_buffer.
2551 * fports.c (scm_setvbuf): docstring: remove the fcntl documentation
2552 which was incorrectly appended.
2554 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2556 * guile-doc-snarf.in: Don't use absolute path for `sed'. (Note
2557 that we can't use autoconf for this. Autoconf itself relies on
2558 the existence of `sed' somewhere on your path.) (Thanks to Dirk
2561 2000-03-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2563 * Makefile.am (libguile_la_SOURCES): Moved iselect.c here from
2564 EXTRA_libguile_la_SOURCES.
2566 * iselect.h: Always declare scm_internal_select.
2568 * iselect.c (scm_internal_select): Added SCM_ASYNC_TICK at the
2569 end. Also let scm_internal_select be a real function also when
2572 * __scm.h (SCM_TICK): Oops! Forgot to put SCM_ASYNC_TICK here...
2574 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2576 * __scm.h (SCM_ALLOW_INTS, SCM_REALLOW_INTS): Removed call to
2577 SCM_ASYNC_TICK. (This is a preparation for POSIX threads support,
2578 and kind of an experiment: Will this cause problems?)
2580 Sun Mar 12 13:26:30 2000 Greg J. Badros <gjb@cs.washington.edu>
2582 * Makefile.am: Added *.doc to DISTCLEANFILES.
2584 2000-03-12 Gary Houston <ghouston@arglist.com>
2586 * fports.c (scm_fdes_to_port): call fcntl F_GETFL to test that
2587 the fdes is valid before doing anything else. check that
2588 the file descriptor supports the modes required.
2589 (scm_fport_buffer_add): don't throw an error if fstat doesn't
2590 work: just use the default buffer size.
2592 * throw.c: change an outdated comment about scm_internal_catch
2593 BODY: it doesn't take a jumpbuf arg.
2595 * init.c (scm_standard_stream_to_port): install a handler in case
2596 scm_fdes_to_port throws an error. don't check here whether the
2597 file descriptor is valid, since scm_fdes_to_port will do that.
2598 set the revealed count depending on whether the port got the
2599 standard file descriptor.
2600 (stream_body_data): new type.
2601 (stream_body, stream_handler): new procs.
2603 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2605 * stacks.c, stacks.h, struct.c, tags.h, unif.c (scm_bits_t):
2606 Renamed from SCMWORD.
2608 * tags.h (SCM_NCELLP): Removed (SCMWORD).
2610 * arbiters.c (SCM_ARB_LOCKED): Use SCM_UNPACK_CAR.
2612 * async.c, boolean.h, debug.c, dynl.c, dynwind.c, eval.c, eval.h,
2613 feature.h, filesys.h, fluids.h, fports.c, fports.h, gc.c, gc.h,
2614 hash.c, keywords.h, macros.c, numbers.c, numbers.h, objects.c,
2615 objects.h, options.c, pairs.h, ports.c, ports.h, print.c,
2616 procs.h, ramap.c, read.c, smob.c, smob.h, srcprop.h, stacks.c,
2617 stacks.h, strports.c, struct.c, struct.h, tag.c, tags.h,
2618 throw.c, unif.c, unif.h, variable.h, vectors.h, weaks.c,
2619 weaks.h (SCM_PACK, SCM_UNPACK, SCM_UNPACK_CAR): Renamed from
2620 SCM_ASSCM, SCM_ASWORD, SCM_CARW).
2622 * numbers.h (SCM_SRS, SCM_INUM): Corrected SCM_ASSCM/ASWORD fixes.
2624 * alist.c, eval.c, net_db.c, posix.c, print.c, snarf.h, struct.c,
2625 tags.h: Fixed copyright notices.
2627 * struct.c, coop-threads.c: SCM_ASSCM/ASWORD fixes.
2629 2000-03-12 Marius Vollmer <mvo@zagadka.ping.de>
2631 * init.c (scm_standard_stream_to_port): Check whether the file
2632 descriptor is valid and substitute "/dev/null" when not.
2634 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2636 * coop-defs.h (struct timespec): Conditionally defined.
2638 * coop.c (coop_condition_variable_timed_wait_mutex): Use ETIMEDOUT
2641 * readline.c (match_paren): Bugfix: First arg to select is not
2642 number of descriptors but the number of the highest descriptor +
2645 This is a preliminary attempt at a cleanup of the threads support
2646 code. It moves things to better places, makes arguments more
2647 consistent with the POSIX API (which is used in GNOME's glib), and
2648 adds new functionality.
2650 * readline.c (scm_init_readline): Added new arg to scm_init_mutex.
2652 * coop-defs.h (scm_mutex_trylock): New macro: alias for
2654 (scm_cond_init): Changed definition to
2655 coop_new_condition_variable_init.
2657 * coop.c: #include <errno.h>
2658 (coop_timeout_qinsert): Moved here from iselect.c
2659 (coop_new_mutex_init, coop_new_condition_variable_init): New
2660 functions. The strange names are temporary. Use scm_mutex_init
2661 and scm_cond_init instead.
2662 (coop_mutex_trylock): New function. Uses errno.h:EBUSY. errno.h
2663 is ANSI C, but should we check for individual error codes in
2665 (coop_condition_variable_timed_wait_mutex): New function.
2666 (coop_key_create, coop_setspecific, coop_getspecific,
2667 coop_key_delete): New functions.
2669 * iselect.c (coop_timout_qinsert): Moved to coop.c
2671 2000-03-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2673 * pairs.h (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR,
2674 SCM_SETOR_CDR): Corrected SCM_ASSCM/WORD fixes.
2676 * tags.h (SCM_VOIDP_TEST): Renamed from VOIDP_TEST.
2679 * objects.h (SCM_CLASS_FLAGS, SCM_OBJ_CLASS_FLAGS,
2680 SCM_SET_CLASS_INSTANCE_SIZE), struct.h (SCM_STRUCT_VTABLE_DATA),
2681 proc.h (SCM_CLOSCAR): SCM_ASSCM/WORD fixes.
2683 * eval.c (scm_lookupcar1): Inserted SCM_ASWORD in expressions
2686 2000-03-11 Dale P. Smith <dpsm@en.com>, applied by Greg J. Badros, <gjb@cs.washington.edu>
2688 * numbers.c (scm_copy_big_dec, scm_copy_smaller, scm_big_ior,
2689 scm_big_xor, scm_big_and, scm_big_test): Added new lowlevel bignum
2690 logical functions from SCM.
2692 (logand, logior, logxor, logtest, logbit?): Extended scheme
2693 logical functions to use bignums from SCM.
2695 (lognot): Removed call to `SCM_VALIDATE_INUM' that prevented
2696 lognot from using bignums.
2698 Thu Mar 9 11:33:25 2000 Greg J. Badros <gjb@cs.washington.edu>
2700 * vectors.h (SCM_VELTS_AS_STACKITEMS): Added this macro to help in
2701 eliminating some warnings.
2703 * unif.c, strports.c, print.c, options.c: Fix some warnings on
2706 * gc.c, gc.h: Added scm_return_first_int(), and added comment re:
2707 what the scm_return_first* functions do.
2709 2000-03-09 Han-Wen Nienhuys <hanwen@cs.uu.nl>, applied by Greg J. Badros, <gjb@cs.washington.edu>
2711 * libguile/*.[ch]: make a distinction between SCM as a generic
2712 name for a Scheme object (now a void*), and SCM as 32 bit word for
2713 storing tags and immediates (now a long int). Introduced
2714 SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious
2715 code in the process: arbiter.c (use macros), unif.c (scm_array_p),
2717 Wed Mar 8 10:15:59 2000 Greg J. Badros <gjb@cs.washington.edu>
2719 * numbers.c: Use SCM_VALIDATE_LONG_COPY, and longs, not ints, in
2720 various logXXX primitives. Thanks Eric Moore!
2722 Tue Mar 7 08:05:22 2000 Greg J. Badros <gjb@cs.washington.edu>
2724 * run-test, remaining-docs-needed: Added these scripts. The
2725 second one is only temporary until the docstring additions are
2726 complete. run-test may best live on, but is here mostly for
2727 convenience and awareness for now.
2729 * hash.c: Docs, minor cleanup patch from Dirk Herrman.
2731 Thu Mar 2 16:06:58 2000 Greg J. Badros <gjb@cs.washington.edu>
2733 * error.h, error.c: Added `scm_wrong_type_arg_msg' to support
2734 displaying the expected type. Use SCM_LISTn in a couple places
2735 instead of scm_cons-ing by hand.
2737 * __scm.h: Added SCM_ASSERT_TYPE macro.
2739 * validate.h, scm_validate.h: Added the former, as a renamed
2740 version of the latter with SCM_ASSERT_TYPE used in
2741 SCM_MAKE_VALIDATE (instead of just SCM_ASSERT)
2743 * Makefile.am: Rename scm_validate.h to validate.h.
2745 * *.c, *.h: Include validate.h, not scm_validate.h (old name's
2746 prefix was superfluous).
2748 Thu Mar 2 15:33:12 2000 Greg J. Badros <gjb@cs.washington.edu>
2750 * hashtab.c: Improved documentation for lots of functions. Added
2751 handwritten docs for `hash-fold'.
2753 Thu Mar 2 15:13:25 2000 Greg J. Badros <gjb@cs.washington.edu>
2755 * list.c: Added hand-written docs for `del{q,v,ete}1!'.
2757 Thu Mar 2 12:38:30 2000 Greg J. Badros <gjb@cs.washington.edu>
2759 * list.c: Moved append docs to append! Thanks Dirk Hermann. Also,
2760 added append docs from R4RS.
2762 * strings.c: Docstring typo fix, + eliminate unneeded IMP tests.
2763 Thanks Dirk Hermann!
2765 * chars.h: Provide SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR and
2766 deprecate SCM_ICHRP, SCM_ICHR, SCM_MAKICHR. Thanks Dirk Hermann!
2768 * *.h, *.c: Use SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR throughout.
2769 Drop use of SCM_P for function prototypes... assume an ANSI C
2770 compiler. Thanks Dirk Hermann!
2772 Sat Feb 19 12:20:12 2000 Greg J. Badros <gjb@cs.washington.edu>
2774 * ports.c: Made `set-port-column!' and `set-port-line!' each
2775 return SCM_UNSPECIFIED instead of a (not-scheme-object) integer
2776 that caused a seg fault. Also fixed `set-port-column!'s
2777 docstring. Thanks Han-Wen Nienhuys for finding the bug!
2779 Sun Feb 13 19:11:42 2000 Greg J. Badros <gjb@cs.washington.edu>
2781 * arbiters.c, eq.c, gc.c, guardians.c, list.c, ports.c, print.c,
2782 regex-posix.c, scmsigs.c, stime.c, strings.c, variable.c, stime.c,
2783 strings.c, variable.c: Added lots of documentation, cleaned up
2784 some existing documentation. Occasionally changed formal params
2785 to match docs. Also folded an #ifdef into the inners of a
2786 primitive instead of having two copies of the primitive
2787 (`get-internal-real-time', from stime.c)
2789 Sun Feb 13 18:12:19 2000 Greg J. Badros <gjb@cs.washington.edu>
2791 * ports.c: Added docs for primitives missing them. Written by
2794 Sun Feb 13 09:40:36 2000 Greg J. Badros <gjb@cs.washington.edu>
2796 * guile-doc-snarf.in: Use ${AWK} -f guile-func-name-check, not
2797 just execing guile-func-name-check. Thanks Michael Livshin!
2799 Thu Feb 10 11:43:23 2000 Greg J. Badros <gjb@cs.washington.edu>
2801 * guile-snarf.awk.in: Tweak to work with Sun/HP awk, removed some
2802 dead code. Patch from Michael Livshin.
2804 * guile-doc-snarf.in: Tweak to work with Sun/HP sh. Patch from
2807 2000-02-09 Gary Houston <ghouston@arglist.com>
2809 * init.c (scm_init_standard_ports): when stdout is a tty, make the
2810 current-output-port unbuffered by default. this is less confusing
2811 for interactive use. it was line-buffered because of a
2812 performance problem with unbuffered ports, but I think it will be
2815 2000-02-08 Gary Houston <ghouston@arglist.com>
2817 * __scm.h: don't define long_long or ulong_long if HAVE_LONG_LONGS
2820 * stime.c (scm_localtime, scm_mktime): if neither HAVE_TM_ZONE nor
2821 HAVE_TZNAME are defined, use an empty string instead of giving two
2822 spurious compile-time errors.
2824 Tue Feb 8 13:57:46 2000 Greg J. Badros <gjb@cs.washington.edu>
2826 * ports.c: Doc patches from Richard Kim. Pasted from MIT Scheme.
2829 Mon Feb 7 09:07:31 2000 Greg J. Badros <gjb@cs.washington.edu>
2831 * macros.c: Doc patches from Richard Kim. Pasted from scm.texi.
2833 Sun Feb 6 20:26:21 2000 Greg J. Badros <gjb@cs.washington.edu>
2835 * pairs.c: Doc patches from Richard Kim. Pasted from MIT Scheme
2836 (which is GNU GPL'd).
2838 2000-01-31 Gary Houston <ghouston@arglist.com>
2840 * strings.h: don't use SCM_P. don't include <string.h>.
2841 * error.c, gh_data.c, ports.c, script.c, strop.c: include <string.h>.
2843 * strings.c (scm_string_ref): make the 2nd argument compulsory.
2844 previously it defaulted to zero for no good reason that I can see.
2845 use a local variable for SCM_INUM (k). replace
2846 SCM_VALIDATE_INUM_DEF with SCM_VALIDATE_INUM_COPY.
2848 (scm_makfromstr): cosmetic changes.
2850 (scm_string): Accept only chars in the list, not strings, for
2851 conformance to R5RS (particularly for list->string, which is
2852 supposed to be the inverse of string->list.) remove
2853 SCM_DEFER_INTS/SCM_ALLOW_INTS, which is unnecessary since
2854 scm_makstr handles the cell allocation. when reporting wrong-type
2855 arg, don't report the position as 1.
2857 * posix.c (scm_init_posix): intern PIPE_BUF if it's defined.
2859 2000-01-29 Gary Houston <ghouston@arglist.com>
2861 * posix.c (scm_pipe): rewrote the docstring.
2863 * filesys.c (scm_select, retrieve_select_type, get_element,
2864 fill_select_type, set_element): modified so that Scheme
2865 "select" tests port buffers for the ability to provide input
2866 or accept output. Previously only the underlying file descriptors
2867 were checked. Rewrote the docstring.
2869 Thu Jan 27 10:14:25 2000 Greg J. Badros <gjb@cs.washington.edu>
2871 * vectors.c, symbols.c, strorder.c: Documentation cut and pasted
2872 from Gregg Reynolds. Thanks Gregg!
2874 Thu Jan 27 09:59:38 2000 Greg J. Badros <gjb@cs.washington.edu>
2876 * strop.c (scm_i_index): Obfuscated commented-out SCM_DEFINE by
2877 adding "x" prefix to the line so that guile-func-name-check
2878 doesn't complain unnecessarily.
2880 Wed Jan 26 17:33:52 2000 Greg J. Badros <gjb@cs.washington.edu>
2882 * throw.c: Factor out an #ifdef/#else/#endif choice more finely
2883 for maintainability.
2885 * strop.c: Documentation added by Gregg A. Reynolds. Pasted in
2888 Wed Jan 26 10:02:11 2000 Greg J. Badros <gjb@cs.washington.edu>
2890 * tag.c: Added doc for `tag', but mark as deprecated since Mikael
2891 suggests removing tag.c altogether (and using a new `class-of'
2894 * strings.c: Added documentation from Gregg A. Reynolds. Edited
2895 a bit by me to use FOO instead of @var{foo} and to have the
2896 summary come before preconditions on input. Also dropped trailing
2899 * gsubr.c: Do not use SCM_DEFINE for `gsubr-apply'. Register the
2900 function with scm_make_subr_opt w/ last arg of 0 so it is not
2901 visible at the Scheme level. Mikael says that this is the right
2902 thing because the first arg to the proc is the guts of a compiled
2903 closure and shouldn't be exposed to the Scheme level.
2905 Tue Jan 25 17:15:47 2000 Greg J. Badros <gjb@cs.washington.edu>
2907 * sort.c: typo in comment fixed.
2909 * keywords.c: Added documentation.
2911 * guardians.c: Added documentation (could be better).
2913 * gc.c: Added docs for gc-set-debug-check-freelist.
2915 * eq.c: Added docs for eq?, eqv? equal? abridged from R4RS.
2917 * boolean.c: Added docs for `not', `boolean?' (by hand).
2919 Tue Jan 25 13:28:56 2000 Greg J. Badros <gjb@cs.washington.edu>
2921 * random.c: Added documentation, from SLIB page:
2922 http://angela.ctrl-c.liu.se/~calle/scheme/slib_toc.html
2924 Mon Jan 24 17:50:20 2000 Greg J. Badros <gjb@cs.washington.edu>
2926 * variable.c, version.c: Added documentation, written by hand
2927 since I could not find anything already written that was
2930 2000-01-23 Gary Houston <ghouston@arglist.com>
2932 * filesys.c (scm_chown): omit port/fdes support if HAVE_FCHOWN is
2933 not defined (thanks to Richard Y. Kim).
2935 Thu Jan 20 13:00:38 2000 Greg J. Badros <gjb@cs.washington.edu>
2937 * Makefile.in: Removed, this is auto-generated.
2939 Thu Jan 20 11:33:47 2000 Dirk Hermann <dirk@ida.ing.tu-bs.de> --applied 01/20/00 gjb
2941 * list.c: Put some variable initialization code at the point of
2942 declaration; Added a comment for list*; Formatting changes.
2944 * load.c: use SCM_NNULLP to make sure the end of a list is not
2947 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2949 * backtrace.c (scm_display_error_message): Bugfix: Don't use
2950 result of scm_list_p as C boolean.
2951 (scm_display_error_message, scm_set_print_params_x): Use new
2952 validation macros. (Thanks to Dirk Herrmann.)
2954 * net_db.c (scm_resolv_error): Cast result from hstrerror.
2956 * strports.c (st_end_input): Inserted parenthesis to get operator
2959 * list.h (scm_init_list): Removed SCM_P around prototypes.
2961 * fports.c, list.c, numbers.c, ports.c, stime.c, symbols.c,
2962 filesys.c, posix.c: Converted docstrings to ANSI C format and
2963 escaped " occurring inside string literals.
2965 Tue Jan 18 13:21:08 2000 Mikael Djurfeldt <mdj@r11n07-s.pdc.kth.se>
2967 * posix.c (scm_mknod): Escape " occuring inside docstring.
2969 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2971 * alist.c, chars.c, debug.c, dynl.c, dynwind.c, error.c, eval.c,
2972 evalext.c, filesys.c, gc.c, hash.c, hashtab.c, ioext.c,
2973 keywords.c, list.c, load.c, macros.c, net_db.c, numbers.c,
2974 objprop.c, ports.c, posix.c, print.c, procprop.c, procs.c,
2975 ramap.c, regex-posix.c, root.c, scmsigs.c, simpos.c, socket.c,
2976 stacks.c, stime.c, strings.c, strop.c, strports.c, struct.c,
2977 symbols.c, throw.c, unif.c, vectors.c, version.c, vports.c,
2978 weaks.c: Converted docstrings to ANSI C format.
2980 * filesys.c (scm_chmod), simpos.c (scm_system), version
2981 (scm_version), vports (scm_make_soft_port): Escape " occuring
2984 Mon Jan 17 11:41:22 2000 Greg J. Badros <gjb@cs.washington.edu>
2986 * scm_validate.h: Added SCM_VALIDATE_ULONG_COPY,
2987 SCM_VALIDATE_LONG_COPY
2989 * numbers.c: Use SCM_VALIDATE_ULONG_COPY, instead of
2990 SCM_VALIDATE_INUM_COPY to let bigger numbers be used. Rename a
2991 couple of formal arguments (and fix their uses) to make arguments
2992 match the documentation.
2994 2000-01-14 <mstachow@alum.mit.edu>
2996 * Makefile.am: Augment path when running guile-doc-snarf so
2997 guile-func-name-check is found.
2999 Fri Jan 14 09:34:55 2000 Greg J. Badros <gjb@cs.washington.edu>
3001 * scm_validate.h (SCM_NUM2LONG_DEF): Fix this macro to just use
3002 def, not SCM_MAKINUM(def); thanks Janis Bzerins!
3004 Wed Jan 12 00:06:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3006 * net_db.c (s_scm_inet_makeaddr): Use SCM_NUM2ULONG since that's
3007 the way guile-1.3.4 worked, but #if 0 out the version using
3008 SCM_VALIDATE_INUM_COPY for stricter testing.
3010 Tue Jan 11 18:24:18 2000 Greg J. Badros <gjb@cs.washington.edu>
3012 * guile-doc-snarf.in: Use new $fullfilename for running
3013 guile-func-name-check, and put "$fullfilename" and "$filename" in
3014 quotes at uses to make sure re-splitting on whitespace does not
3015 occur (so filenames w/ embedded whitespace would work okay, though
3016 I sure hope we never have to deal with that! :-) ). Thanks to
3017 Mikael for pointing out the source_dir != build_dir was broken.
3019 Tue Jan 11 17:42:40 2000 Greg J. Badros <gjb@cs.washington.edu>
3021 * scm_validate.h: Added SCM_NUM2LONG_DEF macro. Make
3022 SCM_OUT_OF_RANGE use SCM_MAKINUM, not scm_long2num. Added
3023 SCM_COERCE_ROSTRING macro. Added SCM_VALIDATE_NONEMPTYLIST
3024 macro. Fix SCM_VALIDATE_STRINGORSUBSTR macro to not use SLOPPY
3027 * ports.c (scm_port_closed_p): Validate that the arg is a PORT,
3028 then return whether it's an open port (was validating that it was
3029 an open port -- this was a bug I introduced back in December, but
3030 my careful reading of diffs caught it).
3032 * numbers.c: Recombine the two conditional-compilation paths for
3033 all the log* primitives -- they were split based on #ifndef
3034 scm_long2num; factored out a SCM_LOGOP_RETURN macro, and fixed
3035 some bugs and inconsistencies in the two sets of implementations.
3036 (scm_lognot) Fixed *atrocious* re-use of a SCM as an integer!
3038 * ioext.c: Use SCM_ASSERT_RANGE in a couple places, and
3039 SCM_VALIDATE_INUM_COPY once where it should've been used.
3041 * fluids.c (scm_internal_with_fluids): Use
3042 SCM_VALIDATE_LIST_COPYLEN.
3044 * filesys.c: Use SCM_NUM2LONG instead of SCM_VALIDATE_INUM_COPY;
3045 this is questionable as it relaxes type safety, but other changes
3046 were useful and all SCM_NUM2LONG's should probably be
3047 revisited. Use SCM_OUT_OF_RANGE, SCM_WRONG_TYPE_ARG.
3049 * evalext.c: line-break change on 1 line.
3051 * eval.c (nconc2last): Takes a non-empty list as its first
3052 argument, not just a list.
3054 * dynl.c: Use new SCM_COERCE_ROSTRING macro.
3056 Tue Jan 11 15:44:23 2000 Greg J. Badros <gjb@cs.washington.edu>
3058 * dynl.c, feature.c, filesys.c, fports.c, list.c, load.c,
3059 net_db.c, sort.c, stacks.c, unif.c: Use SCM_WTA, SCM_MISC_ERROR
3062 * symbols.c (scm_sysintern0): Fixed the function name in a
3063 scm_misc_error invocation.
3065 * print.c (scm_simple_format): Do not need SCM_COERCE_SUBSTR, and
3066 use scm_return_first to ward off latent GC bug that Mikael caught.
3068 * async.c: Use SCM_VALIDATE_ASYNC_COPY one place where it wasn't
3069 used before but should've been.
3071 2000-01-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3073 * snarf.h (SCM_PROC1): Replaced SCM (*) (...) with
3074 SCM_FUNC_CAST_ARBITRARY_ARGS.
3076 Tue Jan 11 13:44:07 2000 Greg J. Badros <gjb@cs.washington.edu>
3078 * guile-func-name-check.in: Added this script to statically check
3079 #define FUNC_NAME, #undef FUNC_NAME in the source.
3081 * sort.c, posix.c: Fix #undef FUNC_NAME lines to not have trailing
3082 redundant comment, semicolon; caught by new guile-func-name-check
3085 * debug.c: Fix mistaken #define FUNC_NAME for scm_make_iloc.
3086 Caught by new guile-func-name-check-script.
3088 * Makefile.am: Added guile-func-name-check to bin_SCRIPTS
3090 * ramap.c: Fix #if 0'd out code to be syntactically acceptable to
3091 guile-func-name-check.
3093 * guile-doc-snarf.in: Run guile-func-name-check on the file before
3096 Tue Jan 11 11:31:10 2000 Greg J. Badros <gjb@cs.washington.edu>
3098 * fports.c, ports.c, ports.h, strports.c, vports.c: Make write
3099 port function take const void*, not void*.
3101 Tue Jan 11 11:18:07 2000 Greg J. Badros <gjb@cs.washington.edu>
3103 * scm_validate.h, chars.c, ports.c, print.c, read.c, strings.c,
3104 strop.c: Use SCM_VALIDATE_ICHR, SCM_VALIDATE_ICHR_COPY instead of
3105 SCM_VALIDATE_CHAR, SCM_VALIDATE_CHAR_COPY. Change made for
3106 consistency with the other macros dealing with immediate
3107 characters. (Similar to INT -> INUM change a week or so ago).
3109 Tue Jan 11 10:41:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3111 * dynl.c, error.c, eval.c, feature.c, filesys.c, fports.c, list.c, load.c,
3112 net_db.c, read.c, socket.c: Update error messages to use ~A for
3113 %s, ~S for %S to work with new `simple-format' format and be
3114 standardized better.
3116 * print.h, print.c (scm_simple_format): Added `simple-format'
3117 primitive. It's the old scm_display_error, with ARGS now a rest
3118 parameter, and the destination first instead of last (and a couple
3119 new capabilities inspired by `format' -- #t as destination means
3120 current-output-port, #f means return the formatted text as a
3123 * gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
3125 * backtrace.c (scm_display_error_message): Rewrote to use
3126 scm_simple_format() procedure.
3128 * __scm.h: Added commented-out #define of GUILE_DEBUG_FREELIST
3130 2000-01-09 Marius Vollmer <mvo@zagadka.ping.de>
3132 Finally applied the libltdl patch from Thomas Tanner, with slight
3135 * DYNAMIC-LINKING: Removed because it is obsolete.
3136 * dynl.c: Use ANSI prototypes.
3137 (sysdep_dynl_link): Use lt_dlopenext instead of lt_dlopen.
3138 * scmconfig.h.in: Do not change, as it is automatically generated.
3140 1999-07-25 Thomas Tanner <tanner@ffii.org>
3142 * dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c: deleted
3144 * Makefile.am: likewise, add INCLTDL (libltdl headers) to
3145 INCLUDES, set dlpreopened files in LDFLAGS, link libguile
3147 * dynl.c: use libltdl if DYNAMIC_LINKING is enabled,
3148 * guile.c: register preloaded modules
3149 * scmconfig.h.in: remove obsolete symbols
3151 2000-01-09 Gary Houston <ghouston@arglist.com>
3153 * These changes should make it unnecessary to call tzset from
3154 Scheme after modifying the TZ environment variable, even if the
3155 system date facilities cache the value.
3156 * stime.c (setzone, scm_localtime): added comments.
3157 (tzset): don't define a noop tzset macro if HAVE_TZSET not defined.
3158 (setzone): don't call tzset.
3159 (restorezone): call tzset only if HAVE_TZSET is defined.
3160 (scm_tzset): don't define if HAVE_TZSET not defined. Change the
3161 doc string to indicate that this procedure isn't likely to do
3163 (scm_localtime, scm_strftime, scm_mktime): call tzset if
3164 LOCALTIME_CACHE is defined.
3166 2000-01-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3168 * posix.c (scm_sync): Return SCM_UNSPECIFIED.
3170 2000-01-09 Gary Houston <ghouston@arglist.com>
3172 * eval.c: define scm_unbound_variable_key ('unbound-variable).
3173 scm_lookupcar1: throw an error with key 'unbound-variable instead
3174 of 'misc-error when an unbound variable is encountered.
3176 * filesys.c (scm_mkdir, scm_rmdir, scm_getcwd, scm_select,
3177 scm_symlink, scm_readlink, scm_lstat),
3178 posix.c (scm_setpgid, scm_setsid, scm_ctermid, scm_tcgetpgrp,
3179 scm_tcsetpgrp, scm_uname, scm_setlocale, scm_mknod, scm_nice,
3181 simpos.c (scm_system),
3182 stime.c (scm_times, scm_strptime):
3183 move the HAVE_XXX feature tests out of the procedure bodies.
3184 don't use SCM_SYSMISSING.
3185 scm_validate.h (SCM_SYSMISSING): removed.
3186 error.h, error.c (scm_sysmissing): comment that this is deprecated.
3187 see ChangeLog entry for 1999-12-28.
3189 Sat Jan 8 19:52:04 2000 Greg J. Badros <gjb@cs.washington.edu>
3191 * scm_validate.h (SCM_VALIDATE_BOOL_COPY): Fix typo.
3193 Sat Jan 8 17:06:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3195 * backtrace.c: Fix spelling typo in a comment.
3197 * snarf.h: Use new SCM_DOCS macro to encapsulate the non SCM_INIT
3198 text. Reformatted some of the expansions.
3200 Fri Jan 7 15:50:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3202 * scm_validate.h (SCM_OUT_OF_RANGE): Use scm_out_of_range_pos to
3203 report the position of the argument.
3205 * error.h, error.c (scm_out_of_range_pos): Added this function to
3206 take extra "pos" argument, the position number of the errant
3209 * debug.c: Use SCM_OUT_OF_RANGE instead of scm_out_of_range.
3211 * snarf.h: Use SCM_HERE and SCM_INIT as names, not SCM_NOTSNARF
3212 and SCM_SNARFING. Also put the %%% in the SCM_INIT since Mikael
3213 prefers that and I'm reasonably indifferent.
3215 Fri Jan 7 15:03:32 2000 Greg J. Badros <gjb@cs.washington.edu>
3217 * snarf.h: Factor out differences between C++ and non-C++ into
3218 SCM_FUNC_CAST_ARBITRARY_ARGS macro. Modify all the snarf macro
3219 definitions to use SCM_NOTSNARF and SCM_SNARFING macros (like
3220 Mikael's macros, below, but changed names and SCM_SNARFING no
3221 longer expands to include %%% -- that must appear in the argument
3222 so that the token appears at the call-site as a reminder).
3224 2000-01-07 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3226 * snarf.h (SCM_INSITU, SCM_INIT): New snarf macros for use in user
3227 snarf macro definitions.
3229 2000-01-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3231 * chars.c (scm_integer_to_char): Use Greg's nice
3232 SCM_VALIDATE_INUM_RANGE macro for argument checking for closer
3235 Thu Jan 6 11:48:49 2000 Greg J. Badros <gjb@cs.washington.edu>
3237 * *.c, snarf.h: Replace GUILE_PROC1 with SCM_DEFINE1 throughout.
3239 Thu Jan 6 11:22:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3241 * Makefile.am (ETAGS_ARGS): Switch to SCM_DEFINE, SCM_DEFINE1
3242 instead of GUILE_PROC.
3244 Thu Jan 6 11:21:49 2000 Greg J. Badros <gjb@cs.washington.edu>
3246 * alist.c: Do not report mismatch errors on some uses of `tmp' (do
3247 this by using SCM_ARG2 instead of `2' in the SCM_VALIDATE_CONS
3250 Thu Jan 6 09:54:33 2000 Dirk Herrmann <dirk@ida.ing.tu-bs.de> --gjb applied
3252 * scm_validate.h: Remove some redundant NIMP tests.
3254 * alist.c: minimize scope of the tmp variables, and initialize
3255 them when declared. The strange SCM_NIMP tests are replaced by
3256 SCM_CONSP tests that more closely reflect the intended semantics.
3257 However, we don't get a performance penalty here, because the
3258 SCM_CONSP test was performed by the ALISTCELL test anyway. * The
3259 extremely ugly use of ASRTGO macros was removed: The calls to
3260 ASRTGO were not encapsulated by "#ifndef SCM_RECKLESS", but got a
3261 label parameter that only exists when SCM_RECKLESS is not defined.
3262 This works, because ASRTGO itself is defined in a way that it only
3263 makes use of the label parameter if SCM_RECKLESS is not defined
3264 (shudder!). Does guile make at all use of the possibility to
3265 define SCM_RECKLESS? * Codesize is likely to be reduced, since
3266 instead of two calls to SCM_ASSERT performed by the ALISTCELL test
3267 we now only get one test.
3269 * list.c: Use SCM_NNULLP, not SCM_NIMP as appropriate. Also use
3270 SCM_NULLP instead of SCM_IMP. Drop use of "register" keyword on
3271 some variables in `list?'. Fix `reverse' and `reverse!'
3272 primitives to handle improper lists better.
3274 Wed Jan 5 11:24:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3276 * *.[ch]: Whitespace changes -- added space after SCM_VALIDATE_*
3277 macros and SCM_DEFINE macros to match GNU coding standards.
3279 Wed Jan 5 11:04:24 2000 Greg J. Badros <gjb@cs.washington.edu>
3281 * *.[ch]: Replace GUILE_PROC w/ SCM_DEFINE.
3283 Wed Jan 5 10:59:06 2000 Greg J. Badros <gjb@cs.washington.edu>
3285 * *.[ch]: Replace SCM_VALIDATE_INT w/ SCM_VALIDATE_INUM for
3286 better consistency with the names of other SCM_VALIDATE_ macros
3287 and better conformance to guile naming policy.
3289 Wed Jan 5 10:50:39 2000 Greg J. Badros <gjb@cs.washington.edu>
3291 * ports.c (s_scm_close_all_ports_except): Use SCM_ARG1 in a
3292 SCM_VALIDATE instead of 1 to avoid a check on the argument (since
3293 it's not the actual name of the formal).
3295 * guile-snarf.awk.in: Do argument/number mismatch checking and
3296 print warnings in an Emacs compile-mode parseable format.
3298 * struct.c: Use SCM_ASSERT_RANGE instead of SCM_ASSERT w/
3299 SCM_OUTOFRANGE as 3rd argument.
3301 * random.c: Fix argument/number mismatch (that I introduced :-( ).
3303 * __scm.h: Do not #define SCM_ARG* when snarfing;
3304 lets us distinguish between 1 and SCM_ARG1 when snarfing as only
3305 the former (using the number) requires the argument to match the
3306 formal in the current argument snarfing check.
3308 * snarf.h: Give new definition of SCM_ASSERT when in
3309 snarfing mode to output a lexically-identifiable sequence that the
3310 guile-snarf.awk script uses to verify argument/position matching.
3312 * ramap.c: Remove extraneous #undef FUNC_NAME.
3314 Wed Jan 5 08:36:38 2000 Greg J. Badros <gjb@cs.washington.edu>
3316 * guile-doc-snarf.awk.in: Removed -- guile-snarf.awk.in is the
3317 current version of the same functionality; it writes the .x output
3318 to stdout instead of directly into the file.
3320 Wed Jan 5 08:15:04 2000 Greg J. Badros <gjb@cs.washington.edu>
3322 * unif.c, symbols.c, strings.c, stacks.c, random.c, print.c,
3323 posix.c: Eliminated a bunch of SCM_NIMP(..)s that are now
3324 redundant with the safer macros. Patch from Dirk Hermann applied
3325 by hand. Thanks Dirk!
3327 * scm_validate.h: Added SCM_VALIDATE_VECTOR_OR_DVECTOR for some
3330 * ramap.c: whitespace change.
3332 Tue Jan 4 14:21:35 2000 Greg J. Badros <gjb@cs.washington.edu>
3334 * options.c, objects.c, keywords.c, gc.c: Some redundant SCM_NIMP
3335 removals from Dirk Hermann.
3337 * alist.c: Rename formals to match the parameter names in the
3338 documentation, updates to documentation. Thanks Dirk Hermann!
3340 2000-01-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3342 * eval.c (SCM_CEVAL): Reverse order of
3343 scm_stack_checking_enabled_p and SCM_STACK_OVERFLOW_P
3344 (Thanks to Brad Knotwell.)
3346 Mon Jan 3 08:30:02 2000 Greg Harvey <Greg.Harvey@thezone.net> (applied --01/03/00 gjb)
3348 * gc.c (scm_debug_newcell): Added SCM_SETCAR of the newly
3351 * pairs.h: Added a comment about the need for the SCM_SETCAR in
3354 Mon Jan 3 08:25:19 2000 Greg J. Badros <gjb@cs.washington.edu>
3356 * dynl-vms.c, debug.c, coop-threads.c, backtrace.c, eval.c: More
3357 SCM_NIMP tests that were redundant are now eliminated. Patches
3358 from Dirk Hermann applied by hand.
