3 * gc.c (scm_gc_for_newcell): don't try to do GC if it's blocked,
6 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
8 * async.c (scm_gc_async, scm_gc_vcell, scm_sys_gc_async_thunk):
11 (scm_init_async): Moved initialization for scm_gc_async and
12 scm_gc_vcell to gc.c. Moved initialization of scm_asyncs here
15 * async.h (scm_gc_async): Not globally visible any more.
17 * gc.c (scm_gc_stats): Made callable even from within regions
20 (scm_gc_end): Eliminate the hardcoding of the marking of the
21 scm_gc_async from the gc core.
23 (scm_init_storage): Don't initialize the scm_asyncs list here.
24 This is now done in asyncs.c.
26 (scm_gc_vcell): Moved here from async.c.
28 (gc_async): Renamed from scm_gc_async, moved here from async.c
31 (gc_async_thunk): Renamed from scm_sys_gc_async_thunk and moved
34 (mark_gc_async): New hook function for scm_after_gc_c_hook.
36 (scm_init_gc): Added initialization of scm_gc_vcell and
37 gc_async. Further, add mark_gc_async to scm_after_gc_c_hook.
39 * init.c (scm_boot_guile_1): scm_init_gc requires asyncs to be
42 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
44 * gc.c (scm_igc): Removed commented code that once was intended
45 to unprotect struct types with no instances.
47 * root.h (scm_type_obj_list): Removed.
49 2000-06-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
51 * async.c (scm_init_async): Switch to standard way of smob
54 2000-06-21 Michael Livshin <mlivshin@bigfoot.com>
56 * guile-doc-snarf.in: use cut instead of sed, that's much much
57 faster. also, don't call basename more than needed. and, to gain
58 a couple of microseconds more, don't call cat needlessly. (thanks
61 2000-06-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
63 * guile-snarf.awk.in, guile-snarf.in, snarf.h: Rename SCM__I to
64 SCM_SNARF_INIT_START, SCM__D to SCM_SNARF_DOC_START, SCM__S to
65 SCM_SNARF_DOCSTRING_START and SCM__E to SCM_SNARF_DOCSTRING_END.
67 2000-06-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
69 * eval.c, eval.h (scm_top_level_lookup_closure_var): Added.
70 #include "libguile/fluids.h".
72 * eval.h (SCM_TOP_LEVEL_LOOKUP_CLOSURE): New macro which replaces
73 SCM_CDR (scm_top_level_lookup_closure_var) everywhere.
75 * root.h (scm_top_level_lookup_closure_var,
76 scm_system_transformer): Removed. (It's no sense in having the
77 *variable* be a "fluid".)
79 * root.c (mark_root): Removed marking of
80 s->top_level_lookup_closure_var and s->system_transformer.
82 * modules.c (scm_selected_module): the_module is now a fluid.
84 2000-06-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
86 * gc.h, tags.h: Be kind to compilers which must see hash signs in
87 column 0. (Thanks to Ian Grant.)
89 * numbers.h: Put #ifdef HAVE_LONG_LONGS around declarations using
90 the long_long type. (Thanks to Bernard Urban.)
92 2000-06-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
94 * gc.c, gc.h (scm_default_init_heap_size_1,
95 scm_default_min_yield_1, scm_default_init_heap_size_2,
96 scm_default_min_yield_2, scm_default_max_segment_size): New global
97 variables. Can be customized by the application before booting
98 Guile. (We might want to be able to control these parameters
99 dynamically through the "options interface" in the future, but
100 note that that is additional functionality. Here we're giving
101 default values which the environment variables can override.)
103 * list.c (scm_cons_star): Updated comment.
105 * smob.h: Changed comments for scm_make_smob_type and
106 scm_make_smob_type_mfpe, warning that the latter might be
107 deprecated in a future release.
109 2000-06-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
111 * list.[ch] (scm_cons_star/cons*): Renamed from
114 * list.[ch] (scm_list_star/list*): Provided as a deprecated alias
115 for scm_cons_star/cons*.
117 * gc.c (scm_protect_object): Updated comment.
119 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX): Removed.
121 * tags.h (SCM_UNPACK_CAR, SCM_NDOUBLE_CELLP): Removed.
123 2000-06-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
125 * init.c, init.h (scm_initialized_p): Renamed from `initialized'
128 * gdbint.c (gdb_print): Print warning instead of calling scm_write
129 if Guile isn't yet initialized.
131 * print.c (scm_current_pstate, scm_make_print_state): Simplified
132 tests, using the assumption that Guile has been initialized.
134 Sun Jun 18 14:45:21 2000 Greg J. Badros <gjb@cs.washington.edu>
136 * print.c (s_scm_current_pstate): Do not segfault when the
137 print_state_pool is unitialized in `current-pstate', and better
138 verify its state before altering it in scm_make_print_state().
140 2000-06-18 Michael Livshin <mlivshin@bigfoot.com>
142 * scmsigs.c (s_scm_sigaction): guard the SIGIOT case with an
143 #ifdef -- it's missing on at least one platform. (thanks to
146 2000-06-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
148 * list.c (list*): Added documentation from common-list.scm.
150 2000-06-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
152 * gc.c (scm_unprotect_object): The reference count is guaranteed
153 to be a positive number.
155 2000-06-15 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
157 * eval.c: Updated comment above scm_map.
159 2000-06-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
161 * gc.c (scm_protect_object): Avoid looking up the object handle
163 (scm_unprotect_object): Abort if scm_unprotect_object is called on
164 an unprotected object.
166 2000-06-14 Michael Livshin <mlivshin@bigfoot.com>
168 * gc.c (scm_unprotect_object): fix a nasty typo bug (thanks to
171 2000-06-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
173 * socket.c (scm_getsockopt): Changed type for `optlen' from int to
175 (scm_accept, scm_getsockname, scm_getpeername, scm_recvfrom):
176 Ditto for `tmp_size'.
177 (scm_addr_buffer_size): Changed type from int to size_t.
179 * random.c: #include <string.h>. (Needed by memcpy.)
181 * guile-snarf.awk.in: Replace the dot_doc_file arg with "-",
182 indicating stdin, instead of "" and don't reset ARGC. This is a
183 workaround for `nawk' in AIX 4.3 on RS6000 but, as far as I know,
184 it is correct, and perhaps even better.
186 2000-06-14 Gary Houston <ghouston@arglist.com>
188 * scmsigs.c (scm_init_scmsigs): if HAVE_SIGINTERRUPT is not
189 defined, add SA_RESTART to the sigaction flags correctly
190 (thanks to Dale P. Smith).
192 2000-06-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
194 * strings.c: #include <string.h>. (Thanks to Bill Schottstaedt.)
196 * net_db.c (scm_resolv_error): Only use macro NETDB_INTERNAL if
197 defined. It isn't on sgi irix 5.3. (Thanks to Bill Schottstaedt.)
199 * Makefile.am (.c.doc): Pipe output (the .x contents) to /dev/null.
201 2000-06-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
203 * fports.c (scm_setvbuf): Use `free' instead of `scm_must_free'
204 since read and write buffers are allocated by `malloc'.
206 * Makefile.am: Removed old test code.
208 * gh_test_c.c, gh_test_repl.c: Removed.
210 2000-06-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
212 * iselect.c (SCM_NLONGBITS): Add workaround for the Sun 4.2
215 * inet_aton.c (inet_aton): Cast init value for `cp'.
217 * ramap.c (s_scm_array_fill_x): Cast `ve' properly in case
220 * symbols.c (scm_intern_obarray_soft,
221 scm_sysintern0_no_module_lookup): Cast `name' to unsigned char ptr
222 in calls to scm_strhash.
224 * strports.c (st_resize_port): Substituted SCM_UCHARS for
226 (st_write): Cast argument to strncpy to char ptr.
227 (scm_mkstrport): Substituted SCM_ROUCHARS for SCM_ROCHARS.
228 (scm_strport_to_string): Cast argument to scm_makfromstr to char
231 * ports.c (scm_ungetc): Cast value to unsigned char ptr before
232 storing in putback_buf.
233 (scm_unread_string): Substituted SCM_ROCHARS for SCM_ROUCHARS.
235 * ioext.c (s_scm_read_line): Cast result of call to
236 scm_do_read_line to unsigned char ptr.
238 * gdbint.c (SEND_STRING): Cast argument to char pointer.
240 * fports.c (fport_flush): Declare `ptr' as unsigned char (was
243 * Makefile.am (DOT_DOC_FILES): List doc-files explicitly. (We
244 shouldn't use Make rules which aren't supported by most Make
246 (OMIT_DEPENDENCIES): Defined to "libguile.h ltdl.h". (We don't
247 want these dependencies recorded, since they would get bogus
248 relative paths; libguile.h is only used in gh.h and guile.c.)
249 (EXTRA_DOT_X_FILES, EXTRA_DOT_DOC_FILES): New variables.
250 (guile-procedures.txt): Depend on EXTRA_DOT_DOC_FILES.
251 (modinclude_HEADERS): Removed kw.h.
253 * guile-snarf.in: Change regexp "^SCM__I" --> "^ *SCM__I".
254 (The preprocessor might insert spaces before the identifier.)
256 * snarf.h (SCM_SNARF_HERE, SCM_SNARF_INIT, SCM_SNARF_DOCS):
257 Renamed from SCM_HERE, SCM_INIT, SCM_DOCS.
259 * smob.h (scm_smobfuns): Removed deprecated type.
261 * smob.c, smob.h (scm_newsmob): Removed deprecated function.
262 (Replaced by `scm_make_smob_type'.)
264 * keywords.c (scm_tc16_kw): Removed deprecated type.
265 (Replaced by scm_tc16_keyword.)
267 * kw.h: Removed deprecated header file.
269 * evalext.c (serial-map): Removed deprected alias for scm_map.
270 (Has been replaced by `map-in-order'.)
272 * ramap.c (serial-array-copy!, serial-array-map!): Removed
273 depracted aliases. (Replaced by `array-copy-in-order!' and
274 `array-map-in-order'.)
276 2000-06-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
278 * gc.h (SCM_VALIDATE_CELL): Rewritten.
279 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
280 SCM_SET_CELL_OBJECT): Use new version of SCM_VALIDATE_CELL.
281 (Thanks to Han-Wen Nienhuys.)
283 2000-06-10 Michael Livshin <mlivshin@bigfoot.com>
285 * guile-doc-snarf.in: don't pipe the CPP output right into sed --
286 write it to the temp file first and check the CPP return code.
287 (I introduced this bug earlier, and this probably caused people
288 with non-GNU C preprocessors to get empty *.x files and not to
289 have the build fail right away...).
291 * scmsigs.c (s_scm_sigaction): guard the SIGSYS case with an ifdef
292 -- at least my libc5-based Linux system doesn't define SIGSYS.
294 2000-06-08 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
296 * snarf.h, guile-snarf.awk.in, guile-snarf.in: Replaced snarf
297 markers with identifiers (SCM__I, SCM__D, SCM__S, SCM__E).
298 (Thanks to Bernard Urban.)
300 2000-06-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
302 * modules.c (scm_system_module_env_p): Fixed detection of system
305 2000-06-06 Marius Vollmer <mvo@zagadka.ping.de>
307 * scmsigs.c (scm_sigaction): Silently ignore setting handlers for
308 `program error signals' because they can't currently be handled by
311 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
313 * procs.h (SCM_SET_SUBRF): Added.
315 * procs.c (scm_make_subr_opt): Don't assign to SCM_SUBRF, use
316 SCM_SET_SUBRF instead. Thanks to Bernard Urban for the bug
319 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
321 * gc.h (SCM_CARLOC, SCM_CDRLOC): Don't take the address of a SCM
324 * sort.c (scm_sorted_p, scm_merge, scm_merge_list_x,
325 scm_merge_list_step): Don't take the address of SCM_CAR. Use
326 SCM_CARLOC instead. Thanks to Bernard Urban for the bug report.
328 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
330 * boolean.h (SCM_TRUE_P): Removed, as people might use it as a
331 replacement for !SCM_FALSEP.
333 * backtrace.c (display_error_body), boolean.h (SCM_BOOLP), gc.c
334 (scm_unhash_name), gh_data.c (gh_module_lookup), load.c
335 (scm_primitive_load), print.c (scm_simple_format), procs.c
336 (scm_procedure_documentation), procs.h (SCM_TOP_LEVEL), ramap.c
337 (scm_array_fill_int), scmsigs.c (scm_sigaction), stacks.c
338 (narrow_stack, scm_make_stack, scm_stack_id), symbols.c
339 (scm_string_to_obarray_symbol), throw.c (scm_catch,
340 scm_lazy_catch, scm_ithrow), unif.c (scm_make_uve, scm_array_p,
341 scm_array_set_x, scm_bit_set_star_x, scm_bit_count_star),
342 validate.h (SCM_VALIDATE_BOOL_COPY, SCM_VALIDATE_PROC): Replace
343 uses of SCM_TRUE_P (x) with SCM_EQ_P (x, SCM_BOOL_T).
345 2000-06-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
347 * eval.c (scm_badformalsp): New static function.
348 (SCM_CEVAL): Check arguments for procedure-with-setter closures.
349 (Thanks to Keisuke Nishida.)
351 The major reason for Guile's slow loading speed has been the fact
352 that a chain of Scheme level procedures has been evaluated for
353 every top-level symbol lookup during the first pass through the
356 The following is a kludge which I suggested four years ago, and
357 which I've repeatedly suggested since. Personally, I've never
358 been bothered by Guile's slow loading speed, so I thought I would
359 let someone else do it...
361 But since the new environments will be included first in
362 Guile-1.5, I thought it would make people happy to get the kludge
365 * modules.c: Added #include "libguile/vectors.h";
366 Added #include "libguile/hashtab.h";
367 Added #include "libguile/struct.h";
368 Added #include "libguile/variable.h";
369 Capture Scheme level `module-make-local-var!' to be used in the
370 standard eval closure.
371 (scm_standard_eval_closure): New primitive.
373 * modules.h (scm_standard_eval_closure): Declare.
375 * eval.c (scm_lookupcar): Test for !SCM_CONSP (SCM_CAR (env))
376 instead of SCM_TRUE (scm_procedurep (SCM_CAR (env))).
378 * symbols.c (scm_sym2vcell): Bypass dispatch in the evaluator for
379 standard eval closures.
381 * variable.c: Code layout fixes.
383 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
385 * Makefile.am: Added LIBS line to libpath which accidentally
386 disappeared in the change of 2000-06-01.
387 (Thanks to Dale P. Smith.)
389 2000-06-03 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
391 * scmsigs.c (scm_segfault): Removed. (Was probably added by
392 mistake since it is not mentioned in ChangeLog.)
394 * gc.h (SCM_VALIDATE_CELL): Cast result to (void) in order to
395 avoid compiler warnings in gcc. (Does this work for other
398 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
400 * gc.h (SCM_VALIDATE_CELL): Don't "use" the value returned by
402 (SCM_CARLOC, SCM_CDRLOC): Define directly instead of using
403 SCM_CELL_OBJECT_0 and SCM_CELL_OBJECT_1. It's not correct to take
404 the address of these expressions since they use SCM_VALIDATE_CELL.
405 (Thanks to Bernard Urban.)
407 * dynl.c: Changed #include <ltdl.h> --> #include
408 "libltdl/ltdl.h". (Thanks to Bill Schottstaedt.)
410 2000-06-01 Craig Brozefsky <craig@red-bean.com>
412 * Makefile.am: libguile_la_LDFLAGS gets -version-info args
413 from GUILE-VERSION definition of LIBGUILE version. Added to
414 libpath.h definitions for guileversion and libguileversion which
415 both get their values from GUILE-VERSION definition.
417 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
419 * numbers.h (SCM_BIGP): Don't use SCM_SMOB_PREDICATE in header
420 file: Code using numbers should not be required to include
423 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
425 * coop-threads.c.cygnus, coop-threads.h.cygnus, fsu-pthreads.h,
426 mit-pthreads.c, mit-pthreads.h: Deleted.
428 * Makefile.am (EXTRA_DIST), scmsigs.c, threads.[ch]: Drop
429 references to deleted files and fsu/mit thread support in
432 2000-05-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
434 * hooks.c (symbol_name, scm_create_hook): Restored the original
435 behaviour of scm_create_hook. Changing it was bad as Carl
436 R. Witty has pointed out.
438 * gc.c (scm_init_gc): We can still rely on scm_create_hook to
441 2000-05-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
443 * gc.c (scm_init_gc): Protect scm_after_gc_hook, since this will
444 soon not be done by scm_create_hook any longer.
446 * hooks.c (make_hook, print_hook, scm_create_hook,
447 scm_make_hook_with_name, scm_make_hook), hooks.h (SCM_HOOK_NAME,
448 SCM_HOOK_PROCEDURES, SCM_SET_HOOK_PROCEDURES,
449 scm_make_hook_with_name), init.c (scm_boot_guile_1): Hooks no
450 longer have names. As an intermediate solution, the name
451 predicate is emulated via object properties, but use of this
452 feature is deprecated.
454 * hooks.h (scm_free_hook): Removed, as it is never defined.
456 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
458 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_FIXABLE):
459 Un-deprecated since otherwise user code can't determine whether a
460 number fits into an inum any longer. The names should be changed
463 * numbers.c (scm_big2inum): Eliminated use of SCM_UNEGFIXABLE.
465 * tags.h (SCM_UNPACK_CAR): Deprecated.
467 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
469 * filesys.h (SCM_OPDIRP), fluids.h (SCM_FLUIDP, SCM_FLUID_NUM),
470 fports.h (SCM_OPFPORTP, SCM_OPINFPORTP, SCM_OPOUTFPORTP), hooks.h
471 (SCM_HOOK_ARITY), keywords.h (SCM_KEYWORDP, SCM_KEYWORDSYM),
472 numbers.h (SCM_NUMP, SCM_BIGSIGN, SCM_BDIGITS, SCM_NUMDIGS):
473 Replace SCM_UNPACK_CAR appropriately. Don't access cells via
474 SCM_{SET}?C[AD]R unless they are known to be cons cells.
476 * gc.c (scm_heap_seg_data_t, scm_mark_locations, scm_cellp,
477 init_heap_seg): Remove unused struct member variable 'valid'.
479 2000-05-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
481 * fports.c (fport_write), ports.c (scm_markstream, scm_port_mode,
482 scm_print_port_mode), ports.h (SCM_OPPORTP, SCM_OPINPORTP,
483 SCM_OPOUTPORTP, SCM_INPUT_PORT_P, SCM_OUTPUT_PORT_P, SCM_OPENP),
484 procs.h (SCM_CLOSCAR), unif.h (SCM_ARRAY_NDIM, SCM_ARRAY_CONTP),
485 variable.h (SCM_VARIABLEP): Replace SCM_UNPACK_CAR
488 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
490 * gc.c (free_list_length), hash.c (scm_hasher), macros.c
491 (scm_macro_type), objects.c (scm_class_of), options.c
492 (scm_options), print.c (scm_iprin1), strports.c (st_seek), throw.c
493 (SCM_LAZY_CATCH_P): Replace SCM_UNPACK_CAR appropriately.
495 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
497 * eval.c (scm_macroexp, SCM_CEVAL, scm_force), tags.h: Replace
498 SCM_UNPACK_CAR with SCM_CELL_TYPE or SCM_CELL_WORD_0.
500 * eval.c (scm_force): Add documentation.
502 * eval.c (scm_force, scm_cons_source): Don't access cells via
503 SCM_{SET}?C[AD]R unless they are known to be cons cells.
505 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
507 * strings.h (SCM_NSTRINGP, SCM_NRWSTRINGP), tags.h
508 (SCM_NDOUBLE_CELLP), vectors.h (SCM_NVECTORP): Deprecated.
510 * gc.c (scm_igc), gc.h (SCM_PTR_MASK, SCM_PTR_LT): Removed #ifdef
511 nosve #endif conditionally compiled code.
513 2000-05-23 Michael Livshin <mlivshin@bigfoot.com>
515 * gc.c (scm_heap_seg_data_t): fixed comment for the `span' member.
517 2000-05-22 Michael Livshin <mlivshin@bigfoot.com>
519 * guile-doc-snarf.in: put the preprocessed file through sed to
520 trim all lines to 1024 chars. I hope it doesn't break anybody's
521 sed. we'll see. (note: this is lossy trimming, i.e. the spill
522 isn't wrapped around but actually chopped off. this seemed to me
523 safe because the current snarfer doesn't understand multi-line
524 cookies anyway. in the long term, it would be nice not to depend
525 on AWK for anything.)
527 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): reverted
528 the previous change to this macros, after deciding to torture the
531 2000-05-21 Michael Livshin <mlivshin@bigfoot.com>
533 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): brought
534 the yucky, ugly and nasty conditional compilation back. sorry,
535 but it was either that or requiring GAWK to build Guile.
536 (lots of places): removed the code that implemented the old GC
539 * init.c (scm_boot_guile_1): removed the code conditioned on
540 !GUILE_NEW_GC_SCHEME.
542 * __scm.h: (GUILE_NEW_GC_SCHEME): removed.
544 * gc.c (scm_protect_object, scm_unprotect_object): change the
545 implementation to more efficient (at least in the time complexity
546 sense). the calls should now also be thread-safe -- I suspect
547 that people expect them to be. (thanks to Han-Wen Nienhuys)
548 (lots of places): removed the code that implemented the old GC
551 * hashtab.c (scm_hash_fn_create_handle_x): add missing
552 SCM_REALLOW_INTS before return. I really wonder about the
553 possible interactions between hashtables, threads & GC. it
554 doesn't look healthy at all.
556 2000-05-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
558 * unif.c (scm_bit_count): Fixed the parameter checks. Thanks to
561 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
563 * __scm.h (SCM_DEBUG_CELL_ACCESSES), gc.h (SCM_): Added as a new
564 debug option to verify all accesses to cells actually access
567 * gc.h (SCM_VALIDATE_CELL): Added. Only performs validation if
568 SCM_DEBUG_CELL_ACCESSES is set to 1.
570 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
571 SCM_SET_CELL_OBJECT): Use SCM_VALIDATE_CELL to check every cell

596 2000-05-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
598 * __scm.h (SCM_DEBUG_REST_ARGUMENT): Renamed from
599 SCM_DEBUG_REST_ARGUMENTS in order to clarify that we don't test
600 the actual arguments in the list, but rather the rest argument as
603 * validate.h (SCM_VALIDATE_REST_ARGUMENT): Added.
605 * async.c (scm_noop), eval.c (scm_map, scm_for_each), list.c
606 (scm_list_star, scm_append, scm_append_x), ports.c

609 (scm_make_stack), strings.c (scm_string_append), struct.c
610 (scm_make_struct, scm_make_vtable_vtable): Validate rest arguments.
612 * dynl.c (DYNL_GLOBAL, sysdep_dynl_link, kw_global, sym_global,
613 scm_dynamic_link, scm_init_dynamic_linking), dynl.h
614 (scm_dynamic_link): Removed possibility to pass flags to
615 scm_dynamic_link, as it had no effect anyway.
617 * filesys.c (scm_fcntl): Made single optional rest argument into
618 a standard optional argument.
620 * hooks.c (scm_run_hook): A list of rest arguments is never
623 * list.c (scm_append, scm_append_x), stacks.c (scm_make_stack),
624 strings.c (scm_string_append): Don't perform half-hearted checks
625 to see whether the rest argument forms a proper list any more, use
626 SCM_VALIDATE_REST_ARGUMENTS instead.

635 (ss_handler, handler_message): Make first mandatory rest argument
636 of scm_make_stack into a standard mandatory argument.
638 * unif.c (scm_transpose_array, scm_enclose_array,
639 scm_array_in_bounds_p), unif.h (scm_transpose_array,
640 scm_enclose_array, scm_array_in_bounds_p): Make first mandatory
641 rest argument into a standard mandatory argument.
643 2000-05-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
645 * __scm.h: Added SCM_DEBUG as default debug option. (Thanks to
646 Keisuke Nishida for the suggestion.) Added debug option
647 SCM_DEBUG_REST_ARGUMENTS.
649 * eval.c (scm_map, scm_for_each): Make sure all lists have the
650 same length. Also, removed redundant parameter checks.
652 2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
654 * Makefile.am: Let 'make clean' remove *.x and *.doc files.
656 * __scm.h: Improved explanation of giving options to make.

664 (scm_remainder, scm_modulo), numbers.h (SCM_SRS, SCM_MAKINUM,
665 SCM_INUM): Removed conditionally compiled code for Turbo C.
667 * gdbint.c (gdb_maybe_valid_type_p): Eliminated call to scm_tag.
668 That check can be assumed to be redundant except for very rare
669 conditions that actually indicate broken heap data.
671 2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
673 * numbers.c (scm_logcount, scm_integer_length): Reordered
676 2000-05-15 Gary Houston <ghouston@arglist.com>
678 * stime.c (scm_strftime): don't reset TZ if zone is an empty
679 string. append a "0" to the zone for TZ.
681 2000-05-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
683 * numbers.c (scm_logbit_p, scm_bit_extract): Reordered dispatch
686 (scm_bit_extract): Fixed handling of bignums.

698 (scm_tc16_flo, scm_tc_flo, scm_tc_dblr, scm_tc_dblc): Wrapped
699 deprecated code between #if (SCM_DEBUG_DEPRECATED == 0) #endif.
701 * fports.c (scm_fport_buffer_add), ports.c (scm_input_port_p,
702 scm_output_port_p), print.c (scm_get_print_state), validate.h
703 (SCM_VALIDATE_CHAR): Replace use of deprecated macros
704 SCM_INPORTP, SCM_OUTPORTP, SCM_ICHRP by SCM_INPUT_PORT_P,
705 SCM_OUTPUT_PORT_P, SCM_CHARP, respectively.
707 2000-05-14 Gary Houston <ghouston@arglist.com>
709 * stime.c (scm_strftime): if HAVE_TM_ZONE is not defined, hack the
710 TZ environment variable so that the %Z format returns the zone
711 from the input vector instead of the system default.
713 from Keisuke Nishida:
714 * fports.c (scm_setvbuf): minor docstring fix.
715 * ports.h (scm_generic_fgets): obsolete prototype deleted.
717 2000-05-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
719 * __scm.h: Added new section for debugging options.
721 (SCM_DEBUG_DEPRECATED): If 1, no deprecated code is included to
722 help developers to get rid of references to deprecated code.
724 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_UNEGFIXABLE,
725 SCM_FIXABLE, SCM_FLOBUFLEN): These macros are no longer provided
726 as part of the interface and are marked as deprecated in the
729 * numbers.c (scm_make_real, scm_make_complex): Inlined the
730 corresponding macros SCM_NEWREAL and SCM_NEWCOMPLEX,
733 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX, SCM_INEXP, SCM_CPLXP,
734 SCM_REAL, SCM_IMAG, SCM_REALPART, scm_makdbl, SCM_SINGP,
735 SCM_NO_BIGDIG, SCM_NUM2DBL, scm_dblproc): Deprecated.
737 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
739 * gc.h (scm_cell, SCM_CELL_WORD, SCM_CELL_OBJECT,
740 SCM_SET_CELL_WORD, SCM_SET_CELL_OBJECT): Scheme cells now consist
741 of two scm_bits_t values instead of two SCM values, because it is
742 legal for cell entries to hold values that are not scheme objects.
744 (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR):
745 Use SCM_SETC[AD]R to modify contents of pairs.
747 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
749 * numbers.c (IS_INF, isfinite): Added FIXME comment.
751 (scm_abs, scm_magnitude): Make these two independent of each
752 other. scm_abs now reports an error if given a complex argument.
754 (scm_istr2flo, scm_integer_p). Use SCM_REAL_VALUE instead of
755 SCM_REALPART if the object is known to be real.
757 (scm_init_numbers): No need to use SCM_NEWREAL macro for speed
760 * numbers.h (SCM_SINGP): Set to 0 instead of SCM_BOOL_F.
762 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>

765 values. Remove #ifdef SCM_BIGDIG #endif test.
767 * eval.c (SCM_CEVAL, SCM_APPLY), gh_data.c (gh_scm2floats,
768 gh_scm2doubles), hash.c (scm_hasher), ramap.c (scm_array_fill_int,
769 ramap_rp, scm_array_map_x), random.c (vector_scale,
770 vector_sum_squares), unif.c (scm_make_uve, scm_array_p,
771 scm_array_set_x): Use SCM_REAL_VALUE instead of SCM_REALPART if
772 the object is known to be real. Use SCM_COMPLEXP instead of
773 deprecated SCM_CPLXP. Use SCM_INEXACTP instead of deprecated
776 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
778 * numbers.c: No need to include unif.h.
780 (IS_INF): Returned to old test for now: x == x + 1 will not work
781 for large numbers due to rounding errors.
782 Thanks to Kalle Olavi Niemitalo.
784 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
786 * numbers.c (scm_divbigdig): Removed outdated comment.

795 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
797 * numbers.c (IS_INF): The new test is x == x + 1. The old test
798 x == x/2 did not work for zero values. Thanks to Han-Wen Nienhuys
801 (scm_number_to_string, scm_sum, scm_difference, scm_two_doubles,
802 scm_num2long, scm_num2long_long, scm_num2ulong): Reordered
805 2000-05-09 Marius Vollmer <mvo@zagadka.ping.de>
807 * scmsigs.c (take_signal): Execute SCM_ASYNC_TICK for SIGSEGV,
808 SIGILL and SIGBUS signals. These signals are not continuable and
809 must be handled for real right away.
811 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
813 * numbers.c (scm_zero_p, scm_positive_p, scm_negative_p,
814 scm_real_part, scm_imag_part, scm_magnitude,
815 scm_inexact_to_exact): Reordered dispatch sequence.
817 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
819 * feature.c: No need to include "libguile/smob.h"
821 (scm_loc_features, features, scm_add_feature, scm_init_feature):
822 Removed variable 'scm_loc_features' as a pointer to the SCM value
823 holding the features list. Using variable 'features' instead,
824 which holds the interned pair. Thus, SCM_SETCDR can be used
825 instead of pointer trickery.
827 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
829 * alist.c (scm_acons): Use SCM{_SET}?_CELL_OBJECT as long as a
830 cell is not known to be a valid pair.
832 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
834 * eval.c (ASRTSYNTAX, scm_m_body, scm_m_letrec1): Removed
835 ASRTSYNTAX. Using SCM_ASSYNT instead.
837 (scm_m_body): Don't create a redundant cons cell.
839 (scm_m_do): Removed redundant test 'bodycheck'.
841 (bodycheck): Removed.
843 * stacks.c (stack_depth, read_frame, read_frames): Removed
844 redundant calculation of size, minimized some variable scopes.
846 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
848 * pairs.c (scm_cons, scm_cons2): Use SCM{_SET}?_CELL_OBJECT as
849 long as a cell is not known to be a valid pair.
851 (scm_pair_p): Eliminated redundant SCM_IMP test.
853 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
855 * eval.c (scm_m_body, scm_macroexp, unmemocopy, scm_eval_args,
856 scm_deval_args): Eliminated redundant SCM_IMP tests.
858 * hashtab.c (scm_ihashx, scm_sloppy_assx, scm_delx_x), weaks.c
859 (scm_make_weak_key_hash_table, scm_make_weak_value_hash_table,
860 scm_make_doubly_weak_hash_table): Fixed critical sections.
861 Thanks to Keisuke Nishida.
863 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
865 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest):
866 Fixed some goto-related initialization bugs (introduced by me).
868 2000-05-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
870 * numbers.h (SCM_INUM0): Uses SCM_MAKINUM instead of SCM_PACK.
872 * dynl.c (dynl_obj, DYNL_OBJ, get_dynl_obj): Removed.
874 (DYNL_FILENAME, DYNL_HANDLE): Use SCM_CELL... macros instead of
877 (SET_DYNL_HANDLE): Added.
879 (scm_dynamic_object_p): Simplified.
881 (scm_dynamic_unlink, scm_dynamic_func): Changed comment. Deliver
882 better error message when accessing unlinked dynamic objects.
883 Eliminated call to get_dynl_obj.
885 2000-05-03 Marius Vollmer <mvo@zagadka.ping.de>
887 * scmsigs.c (orig_handlers) [!HAVE_SIGACTION]: Fix declaration to
888 be an array of function pointers instead of being a pointer to an
889 array returning function. Thanks to Kalle Olavi Niemitalo!
891 2000-05-03 Dirk Herrmann <D.Herrmann@tu-bs.de>
893 * numbers.c (scm_divbigbig, scm_divbigint), numbers.h
894 (scm_divbigbig, scm_divbigint): Don't return zero any more to
895 indicate that a division has a remainder, return SCM_UNDEFINED
896 instead. It is improbable that anyone actually used these
897 functions outside of numbers.c. For this reason and due to the
898 change in behaviour the functions are static now. Thus, if
899 surprisingly there are users of these functions they will at least
902 * numbers.c: Removed #ifdef SCM_BIGDIG #endif in those functions,
903 that already have a clean dispatch order. Note: SCM_BIGDIG is
906 * numbers.c (scm_inexact_p): Simplified.
908 * numbers.c (scm_num_eq_p, scm_less_p, scm_max, scm_min,
909 scm_product, scm_num2dbl, scm_angle): Reordered dispatch
910 sequence, thereby fixing some comparisons of SCM values with
913 * numbers.c (scm_divide): Division by zero of inums leads to an
914 error now. (Formerly, an infinite number was returned.)
916 Respect the fact, that scm_divbigbig does now return SCM_UNDEFINED
917 if a division has a remainder.
919 2000-05-02 Gary Houston <ghouston@arglist.com>
921 * Makefile.am (INCLUDES): add ${INCLTDL} (thanks to Tim Mooney).
923 2000-05-02 Dirk Herrmann <D.Herrmann@tu-bs.de>
925 * numbers.c (scm_logtest, scm_division): Reordered dispatch
926 sequence, thereby fixing some comparisons of SCM values with
929 * numbers.h (scm_makdbl): Mark as deprecated at the point of
932 * eval.c (SCM_CEVAL, SCM_APPLY), gh_data.c (gh_double2scm,
933 gh_doubles2scm), numbers.c (scm_istr2flo, scm_max, scm_min,
934 scm_sum, scm_difference, scm_product, scm_divide, scm_sys_expt,

936 scm_real_part, scm_imag_part, scm_magnitude, scm_angle,
937 scm_long2num, scm_long_long2num, scm_ulong2num), ramap.c
938 (ramap_rp, scm_array_map_x), random.c (scm_random,
939 scm_random_uniform, scm_random_normal_vector_x, scm_random_exp),
940 struct.c (scm_struct_ref), unif.c (scm_array_to_list): Replace
941 call to scm_makdbl with a call to scm_make_real or
942 scm_make_complex, depending on whether the imaginary part is known
945 2000-05-01 Gary Houston <ghouston@arglist.com>
947 * scmsigs.c: fix the definition of orig_handlers for the case
948 that HAVE_SIGACTION is not defined (thanks to
949 Kalle Olavi Niemitalo).
951 * Makefile.am: remove include_HEADERS (was libguile.h)
952 libguile.h: moved to top level directory.
954 2000-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
956 * numbers.c (SCM_SWAP): Moved to the top of the file to allow for
959 * numbers.c (scm_modulo, scm_gcd, scm_lcm, scm_logand, scm_logior,
960 scm_logxor): Reordered dispatch sequence, thereby fixing some
961 comparisons of SCM values with integer constants.
963 * number.c (scm_logtest): Removed some redundant SCM_{N}?IMP
966 2000-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
968 * numbers.c (scm_quotient, scm_remainder): Removed code that was
969 conditionally compiled based on BADIVSGNS. BADIVSGNS does not
970 occur anywhere else throughout guile.
972 * numbers.c (scm_quotient): Fixed parameter number in error
975 * numbers.c (scm_remainder): Reordered dispatch sequence.
977 2000-04-25 Gary Houston <ghouston@arglist.com>
979 * posix.c (scm_execlp): docstring fix (thanks to Martin
982 2000-04-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
984 * eval.c (undef_object): Made into a local static variable
985 (suggested by Jost Boekemeier).

989 * pairs.c (cxrs, scm_init_pairs): Simplify initialization of
992 * procs.c (scm_init_iprocs), procs.h (scm_subr, scm_iproc,
993 scm_dsubr, scm_init_iprocs): Removed.
995 * procs.h (SCM_SUBRF, SCM_DSUBRF): Access the cell words
996 directly instead of casting a cell to a C struct.
998 2000-04-22 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1000 Better modularization of GC extensions through new C level GC
1003 * weaks.c (scm_weaks_prehistory): New function: Add

1016 and added to scm_before_mark_c_hook.
1017 (scm_guardian_zombify): Turned into a hook function and added to
1018 scm_before_sweep_c_hook.
1020 * async.c (scm_sys_gc_async_thunk): Run after-gc-hook.
1021 Added #include "libguile/gc.h".
1023 * gc.h: Added #include "libguile/hooks.h".

1026 (scm_before_gc_c_hook, scm_before_mark_c_hook,
1027 scm_before_sweep_c_hook, scm_after_sweep_c_hook,
1028 scm_after_gc_c_hook): New C level hooks.
1029 (scm_after_gc_hook): New Scheme level hook.
1030 (scm_gc_sweep): Moved scanning of weak vectors to weaks.c.
1031 (scm_igc): Moved initialization of scm_weak_vectors and the call
1032 to scm_guardian_gc_init to respective module.
1033 (scm_mark_weak_vector_spines): Moved to weaks.c;
1034 Call to scm_guardian_zombify moved to guardians.c;

1058 the root build directory.
1060 * numbers.c (scm_odd_p, scm_even_p): Use SCM_WRONG_TYPE_ARG
1061 instead of SCM_ASSERT (0, ...). (Some compilers will complain

1372 2000-04-04 Michael Livshin <mlivshin@bigfoot.com>
1374 * async.h: kill the scm_async_t struct. having a heap cell
1375 pretending to be a C struct is not helthy, and is not needed here

1446 separate loop after processing all the currently known live
1447 guardians, so as to not introduce order dependencies (thanks to
1448 Gary Houston). note that the order problems are still there if
1449 some guardians are themselves zombies, but that's a sick case that
1450 I'm not going to worry about.
1451 also, make another outer loop to process zombified

1551 SCM_CEVAL), procs.h (SCM_TOP_LEVEL): Don't use C operators to
1554 (scm_makprom): Smob data is of type scm_bits_t.
1556 2000-03-31 Dirk Herrmann <D.Herrmann@tu-bs.de>
1558 * backtrace.c (display_error_body), debug.c (scm_procedure_source,
1559 scm_reverse_lookup), dynl.c (scm_dynamic_link): Don't use C
1560 operators to compare SCM values.
1562 * debug.c (scm_make_debugobj), debug.h (SCM_DEBUGOBJ_FRAME,
1563 SCM_SET_DEBUGOBJ_FRAME): Update SCM_{SET_}?DEBUGOBJ_FRAME to
1564 access raw cell data with SCM_{SET_}?CELL_WORD_1.
1566 * debug.c (scm_make_debugobj): Don't use SCM_SETCAR to set types.
1568 * debug.c (scm_make_memoized), dynl.c (scm_dynamic_link): Smob
1569 data is of type scm_bits_t.
1571 2000-03-31 Dirk Herrmann <D.Herrmann@tu-bs.de>
1573 * gdbint.c (gdb_maybe_valid_type_p), guardians.c (TCONC_EMPTYP,
1574 scm_guardian_zombify): Use SCM_EQ_P to compare SCM values.
1576 * guardians.c (GUARDIAN): Use SCM_CELL_WORD_1 for raw data.
1578 2000-03-31 Dirk Herrmann <D.Herrmann@tu-bs.de>
1580 * ports.h (scm_port): Change type of stream member to scm_bits_t.
1582 * gdbint.c (unmark_port, remark_port), ports.c (scm_markstream),
1583 strports.c (st_resize_port, scm_mkstrport), vports (sf_flush,
1584 sf_write, sf_fill_input, sf_close, scm_make_soft_port): Since
1585 streams are now of type scm_bits_t, SCM streams have to be
1588 * ports.h (SCM_SETPTAB_ENTRY, SCM_SETSTREAM): Cast input to
1591 2000-03-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1593 * coop-defs.h (struct coop_t): Added `sto'-field again because of
1594 binary compatibility---let's remove it next time we alter some
1597 * coop.c (coop_quitting_p, coop_cond_create, coop_mutex_create,
1598 coop_mother, coop_child): New variables.
1599 (mother): New function.
1600 (coop_create): New thread spawning mechanism which uses a "mother
1601 thread". The "dummy" pthreads aren't healthy enough to give birth
1602 to new threads since Linux threads thinks they are asleep.
1604 * coop-defs.h (struct coop_t): Removed dummy_mutex.
1606 * coop-defs.h, coop-threads.c (struct coop_t): Eliminate
1607 `sto'-field when GUILE_PTHREAD_COMPAT is enabled.
1609 2000-03-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
1611 * arbiters.c (scm_make_arbiter), async.c (scm_async), dynwind.c
1612 (scm_internal_dynamic_wind): Smob data is always of type
1615 * arbiters.c (SCM_ARB_LOCKED, SCM_LOCK_ARB, SCM_UNLOCK_ARB):
1616 Access the locking information in cell entry 0 with
1617 SCM_{SET_}?CELL_WORD_0 instead of SCM_*CAR.
1619 * async.c (scm_run_asyncs): Use SCM_NULLP to test for the empty
1622 * dynwind.c (scm_dowinds): Use SCM_EQ_P to compare SCM values.
1624 * ports.h (SCM_PTAB_ENTRY, SCM_SETPTAB_ENTRY): Access the ptab
1625 entry data using SCM_{SET_}?CELL_WORD_1 instead of SCM_{SET}?CDR.
1627 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1629 * alist.c (scm_sloppy_assq, scm_assq), eq.c (scm_eq_p, scm_eqv_p,
1630 scm_equal_p), list.c (scm_ilength, scm_last_pair, scm_reverse,
1631 scm_sloppy_memq, scm_delq_x, scm_delq1_x), tags.h (SCM_UNBNDP):
1632 Don't use C operators == and != to compare SCM values, use
1635 * boolean.c (scm_boolean_p): Use SCM_BOOLP to determine whether a
1636 SCM value is equal to #t or #f.
1638 * eq.c (scm_eqv_p, scm_equal_p): Don't use SCM_CAR to access the
1639 cell type entry of non immediate objects of unknown type. Use
1640 SCM_CELL_TYPE instead.
1642 * gh_data.c (gh_scm2bool, gh_module_lookup), list.c
1643 (scm_sloppy_memv, scm_sloppy_member, scm_delv_x, scm_delete_x,
1644 scm_delv1_x, scm_delete1_x), scmsigs.c (scm_sigaction): Use
1645 SCM_FALSEP and SCM_TRUE_P to compare SCM values against #f and
1648 * list.c (scm_listify): Use SCM_UNBNDP to test for an unbound
1651 2000-03-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1653 * coop-threads.c (scm_call_with_new_thread, scm_spawn_thread,
1654 scm_make_mutex, scm_make_condition_variable): Cast data to
1655 scm_bits_t in SCM_SET_CELL_WORD and SCM_NEWSMOB macros.
1657 * coop.c (coop_create): Set `specific' field, not `data' to NULL.
1659 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1661 * smob.h (SCM_NEWSMOB, SCM_NEWSMOB2, SCM_NEWSMOB3, SCM_SMOB_DATA,
1662 SCM_SET_SMOB_DATA, SCM_TC2SMOBNUM, SCM_SMOBNUM): To access smob
1663 data, use SCM_{SET_}?CELL_TYPE or SCM_{SET_}?WORD_[1-3].
1665 Note that this implies that smob data has always to be passed as
1666 values of type scm_bits_t.
1668 2000-03-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1670 * threads.c (scm_init_threads): Pass 0 size to scm_make_smob_type
1671 for scm_tc16_thread. As the current COOP threads are written, GC
1672 is not supposed to manage storage for threads.
1674 * error.c (scm_error): Don't try to throw an error if
1675 scm_gc_heap_lock is true.
1677 * coop.c (coop_finish): New function. Called at exit.
1678 (coop_aborthelp): Free thread structures when threads die.
1679 Finished LinuxThreads compatibility support => COOP threads now
1680 mesh with LinuxThreads.
1682 * coop-threads.c (scm_call_with_new_thread, scm_spawn_thread):
1683 Changed SETCDR --> SET_CELL_WORD_1.
1685 * coop-threads.c (scheme_launch_thread): Set word 1 of handle to 0
1688 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1690 * boolean.h (SCM_TRUE_P): New macro.
1692 * boolean.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOLP), pairs.h
1693 (SCM_NULLP, SCM_NNULLP): Use SCM_EQ_P to compare SCM values.
1695 2000-03-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1697 * continuations.h (SCM_CONTREGS, SCM_SET_CONTREGS): New macros to
1698 access continuation data.
1700 (SCM_SETJMPBUF): Deprecated. Use SCM_SET_CONTREGS instead.
1702 (SCM_JMPBUF, SCM_DYNENV, SCM_THROW_VALUE, SCM_BASE, SCM_SEQ,
1703 SCM_DFRAME): Use SCM_CONTREGS instead of SCM_CHARS to access
1706 * continuations.c (scm_make_cont), init.c (start_stack),
1707 root.c (scm_internal_cwdr): Use SCM_SET_CONTREGS instead of
1710 2000-03-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1712 * symbols.h (SCM_LENGTH, SCM_SETLENGTH): Access the length field
1713 of strings and symbols by using SCM_{SET_}?CELL_WORD_0.
1715 (SCM_CHARS, SCM_UCHARS, SCM_SETCHARS): Use SCM_{SET_}?CELL_WORD_1
1716 to access the char * field of strings and symbols.
1718 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
1720 * gc.h (SCM_NEWCELL, SCM_NEWCELL2): Use SCM_SET_CELL_TYPE to set
1721 the type entry of a new cell. Added a comment about things to
1722 remember when updating the list of free cells.
1724 (SCM_FREEP, SCM_MARKEDP): Use SCM_CELL_TYPE to access the type
1727 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
1729 * pairs.h (SCM_CAR, SCM_CDR, SCM_SETCAR, SCM_SETCDR): Use
1730 SCM_CELL_OBJECT and SCM_SET_CELL_OBJECT. This change implies that
1731 with strict type checking enabled these macros will only work if
1732 given valid SCM parameters.
1734 (SCM_GCCDR): Moved to tags.h.
1736 * tags.h (SCM_GCCDR): Moved here from pairs.h.
1738 2000-03-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
1740 * tags.h (SCM2PTR, PTR2SCM): Moved to gc.h.
1742 * pairs.h (scm_cell, SCM_CELLPTR, SCM_CELL_WORD*, SCM_CELL_OBJECT*,
1743 SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*, SCM_CELL_TYPE,
1744 SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK, SCM_PTR_GT,
1745 SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC, SCM_NEWCELL,
1746 SCM_NEWCELL2): Moved to gc.h.
1748 (SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR, SCM_SETAND_CDR,
1749 SCM_SETOR_CAR, SCM_SETOR_CDR): Moved to gc.h. These names should
1750 be changed, though, since the macros are not only pair related.
1754 * gc.h (SCM2PTR, PTR2SCM, scm_cell, SCM_CELLPTR, SCM_CELL_WORD*,
1755 SCM_CELL_OBJECT*, SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*,
1756 SCM_CELL_TYPE, SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK,
1757 SCM_PTR_GT, SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC,
1758 SCM_NEWCELL, SCM_NEWCELL2, SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR,
1759 SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR): Moved here from
1762 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
1764 * tags.h (SCM_STRICT_TYPING): New macro that, if defined,
1765 activates strict compile time type checking for variables of
1767 (SCM, SCM_PACK, SCM_UNPACK): Define according to whether
1768 SCM_STRICT_TYPING or SCM_VOIDP_TEST are defined.
1769 (SCM_EQ_P): Defined as a macro equivalent for eq?.
1771 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
1773 * tags.h (SCM_POINTERS_MUNGED): Removed.
1775 * gc.c (scm_gc_sweep, init_heap_seg): Removed use of
1776 SCM_POINTERS_MUNGED, thus fixing some illegal casts to SCM.
1778 2000-03-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
1780 * pairs.h (SCM_CELL_OBJECT, SCM_CELL_OBJECT_[0-3],
1781 SCM_SET_CELL_OBJECT, SCM_SET_CELL_OBJECT_[0-3], SCM_CELL_TYPE,
1782 SCM_SET_CELL_TYPE): Added a set of low level macros for accessing
1784 (SCM_CELL_WORD_[0-3]): Renamed from the SCM_CELL_WORD[0-3].
1786 * procs.h, procs.c: Instead of SCM_{SET_}?CELL_WORD[12], use the
1787 newly introduced SCM_{SET_}?CELL_OBJECT_[12] macros.
1789 2000-03-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1791 * tags.h: Disabled definition of SCM_VOIDP_TEST.
1793 Defining SCM as void * introduces problems which haven't been
1794 handled yet. Developers who work with these issues can enable it
1795 in their working copies.
1797 Disabling this definition exposes a set of newly introduced and
1798 older misuses of types which causes warning messages during
1799 compilation. We'll fix this successively.
1801 * gc.c (scm_mark_locations): Changed * (SCM **) X --> * (SCM *) X
1802 in order to obtain a value of type SCM.
1803 (scm_cellp): Updated with new changes to scm_mark_locations.
1805 * continuations.h (SCM_SETJMPBUF): Cast second arg into SCM.
1807 * continuations.c (scm_make_cont): Removed cast of size_t into
1810 * symbols.h (SCM_SETCHARS): Cast second arg into SCM.
1812 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
1814 * numbers.h (SCM_SETNUMDIGS): Use SCM_BIGSIZEFIELD macro for
1815 shifting, not constant. Thanks to Dale P. Smith.
1817 * numbers.c (scm_sum, scm_difference): Don't test a SCM value
1818 for being less than zero. Decode it to a C value first. Again,
1821 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
1823 * numbers.h, ramap.c, struct.h, vectors.h: Don't use SCM2PTR for
1824 non scheme values. If raw data is stored in SCM variables, it has
1825 to be accessed using SCM_UNPACK until a better solution is found.
1827 2000-03-22 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1829 * tags.h (SCM_ECONSP, SCM_NECONSP): More corrections of
1830 pointer-arithmetic induced by the SCM_PACK/UNPACK change.
1832 * print.c (scm_iprin1): SCM_PACK/UNPACK corrections.
1834 * gc.c (scm_gc_sweep): SCM_PACK/UNPACK corrections.
1836 * eval.c (SCM_CEVAL, scm_unmemocar): SCM_PACK/UNPACK corrections.
1838 * dynwind.c (scm_swap_bindings): SCM_PACK/UNPACK corrections.
1840 * async.c, __scm.h: Removed lots of the old async click logic. It
1841 is possible to reinsert it by defining GUILE_OLD_ASYNC_CLICK in
1842 __scm.h. Let's try this out and dump the old code after the
1843 threads reorganization.
1844 (set-tick-rate, set-switch-rate): Conditionally removed.
1846 2000-03-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1848 * gc.c (scm_gc_mark): Bugfix 1: The recent SCM_PACK/UNPACK change
1849 made SCM values into pointers. This turned an arithmetic
1850 computation of the address of the vcell into a pointer-arithmetic
1851 one, thereby screwing up marking of structs.
1852 Bugfix 2: Removed incompletely introduced loop variable `j' used
1853 when protecting the tail array of a struct.
1855 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
1857 * struct.h (SCM_STRUCT_DATA): Don't cast SCM values to pointers.
1859 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
1861 * symbols.h, symbols.c (scm_strhash): Declare the string
1862 parameter as constant, since it is not modified.
1864 * symbols.c (scm_intern_obarray_soft,
1865 scm_sysintern0_no_module_lookup): Can now pass constant strings
1866 to scm_strhash without need for casting.
1868 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
1870 * vectors.h (SCM_VELTS, SCM_VELTS_AS_STACKITEMS): Don't cast SCM
1871 values to pointers. Use SCM2PTR instead.
1873 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
1875 * async.c (scm_set_tick_rate, scm_set_switch_rate): Don't unpack
1876 results of SCM_INUM.
1878 2000-03-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1880 * init.c (scm_boot_guile_1): Renamed GUILE_GC_TRIGGER_1 -->
1881 GUILE_MIN_YIELD_1, GUILE_GC_TRIGGER_2 --> GUILE_MIN_YIELD_2.
1882 GUILE_MIN_YIELD_X now take *positive* fractions of heap size.
1884 * gc.c, gc.h (SCM_MIN_YIELD_1, SCM_MIN_YIELD_2,
1885 min_yield_fraction, min_yield, adjust_min_yield): Renamed from
1886 SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2, gc_trigger_fraction,
1887 gc_trigger, adjust_gc_trigger.
1889 * gc.c (alloc_some_heap): Further improvement of minimal heap size
1891 (SCM_MAX): New macro.
1892 (scm_freelist_t): New field: collected_1. Previous amount of
1894 (gc_sweep_freelist_finish): Trigger based on two last values of
1895 freelist->collected to avoid unnecessary allocation due to
1897 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2):
1898 Adjusted to 45000 cells, 40% and 40%. Gives quick startup
1899 without extra heap allocation.
1901 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
1903 * numbers.h (SCM_MAKINUM): The parameter to SCM_MAKINUM should
1904 already be a C value. No need to unpack it.
1906 * numbers.c (scm_long_long2num): Cast the parameter to scm_bits_t
1907 if we know it fits into an inum.
1909 * ramap.c (ramap_rp): An scm_tc7_[ui]vect object does point to a
1910 field of long values. In contrast, SCM_VELTS accesses a field of
1913 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1915 * gc.c (scm_gc_stats): Inserted explanation of local_scm_mtrigger
1917 (scm_gc_yield_1): New variable: Holds previous yield. Used to
1918 make better judgements.
1919 (gc_sweep_freelist_finish): Inserted explanation of use of
1922 * print.h, stacks.h, options.c, options.h: Changed C++
1925 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
1927 * tags.h (SCM2PTR, PTR2SCM): Use SCM_PACK / SCM_UNPACK correctly.
1929 * numbers.h (SCM_INUMP, SCM_MAKINUM, SCM_INUM0, SCM_COMPLEX_REAL,
1930 SCM_COMPLEX_IMAG, SCM_NUMP, SCM_BDIGITS): Use SCM_PACK /
1931 SCM_UNPACK / SCM2PTR correctly.
1933 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1935 * gc.c (adjust_gc_trigger): Improved documentation.
1936 (alloc_some_heap): Since gc_trigger is used against
1937 freelist->collected, this is the value which should be used to
1938 predict minimum growth.
1940 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
1942 * eval.h: Fix mixup of packed/unpacked SCM values. (Thanks
1943 Thien-Thi Nguyen for the patch.)
1945 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
1947 * numbers.c (scm_ash): Fixed typing problems with the second
1948 parameter and added some documentation. (Thanks Thien-Thi Nguyen
1949 for indicating the problem.)
1951 2000-03-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1953 * gc.c, gc.h (scm_gc_yield): New variable.
1954 (adjust_gc_trigger): Use scm_gc_yield.
1955 (alloc_some_heap): Use scm_gc_yield instead of
1956 scm_gc_cells_collected.
1958 * coop-threads.c: Addd #include "root.h", #include "strings.h".
1960 * debug.c: Added #include "root.h". (Thanks to Thien-Thi Nguyen.)
1962 * gc.c (scm_gc_for_newcell, adjust_gc_trigger): Improved GC
1963 trigger adjustmeant: Take yield (freed cells) for all freelists
1965 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Tuned
1966 to 50000 cell heap with 45% trigger.
1967 (scm_gc_cells_collected): Reintroduced.
1968 (SCM_HEAP_SIZE): New macro.
1969 (scm_gc_sweep): Reintroduced correct computation of
1970 scm_cells_allocated.
1971 (scm_freelist_t): Corrected commentary for field `cluster_size':
1972 Clustersize counts objects, not cells; New member
1973 `clusters_allocated'.
1975 2000-03-19 Michael Livshin <mlivshin@bigfoot.com>
1977 * *.[hc]: add Emacs magic at the end of file, to ensure GNU
1980 2000-03-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1982 * threads.h: Added #include "libguile/throw.h". (Thanks to
1985 2000-03-18 Michael Livshin <mlivshin@bigfoot.com>
1987 * tags.h: (SCM_DOUBLE_CELLP, SCM_NDOUBLE_CELLP): new macros (bad
1988 names, anyone got any better ones?)
1990 * gc.h: (typedef struct scm_freelist_t) remove from here.
1992 * gc.c: (CELL_UP, CELL_DN) made these macros take additional
1993 parameter (the span).
1994 (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK) new macros.
1995 (typedef struct scm_freelist_t) moved here from gc.h, it had no
1996 business being externally visible.
1997 (typedef struct scm_heap_seg_data_t) renamed from
1998 scm_heap_seg_data, to be style-compliant.
1999 (scm_mark_locations) if the possible pointer points to a
2000 double-cell, check that it's properly aligned.
2001 (init_heap_seg) align double-cells properly, work with the
2002 assumption that the segment size divides cleanly by cluster size.
2003 (round_to_cluster_size) new function.
2004 (alloc_some_heap, make_initial_segment) use round_to_cluster_size
2005 to satisfy the new init_heap_seg invariant.

2064 2000-03-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2066 * gc.c, gc.h: Cleanup of the change of 2000-03-15.
2067 Cluster sizes are now independent of GC trigger values.
2068 GUILE_GC_TRIGGER_n can now specify a relative trigger value:
2069 A negative integer gives fraction of total heap size in percent.
2070 (SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Default values set to -40.
2072 * init.c (scm_boot_guile_1): Introduced new variable
2073 GUILE_MAX_SEGMENT_SIZE; New environment variable names:
2074 GUILE_INIT_SEGMENT_SIZE_1, GUILE_GC_TRIGGER_1,
2075 GUILE_INIT_SEGMENT_SIZE_2, GUILE_GC_TRIGGER_2
2077 2000-03-16 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2079 * __scm.h (GC_FREE_SEGMENTS): Disable this until we have made
2080 freeing of segment work with the new GC scheme. (Thanks to
2081 Michael Livshin.) Oops, also happened to make GUILE_NEW_GC_SCHEME
2082 the default, but I'll let this change stay in CVS Guile since this
2083 code is not expected to contain serious bugs.
2085 2000-03-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2087 * gc.c, gc.h (scm_map_free_list): Define also if GUILE_DEBUG is
2089 (scm_free_list_length): New procedure (GUILE_DEBUG).
2090 Fixed a small but serious bug introduced by the previous change.
2092 * gc.c (scm_gc_sweep): Moved variable n_objects to inner sweep
2093 loop and declare as register.
2095 * gc.c (scm_gc_sweep): Sigh... forgot to clear private freelists
2098 Wed Mar 15 08:27:04 2000 Greg J. Badros <gjb@cs.washington.edu>
2100 * fluids.c: Docstring patch from Keisuke Nishida. Some
2101 reindentation, too, and a couple formals renamed. Should
2102 fluid-set! return UNSPECIFIED instead of a value?
2104 Wed Mar 15 08:24:58 2000 Greg J. Badros <gjb@cs.washington.edu>
2106 * Makefile.am: Separate out DOT_X_FILES and DOT_DOC_FILES, and
2107 generate the latter from the concrete listing of the former. Then
2108 make guile-procedures.txt depend on DOT_DOC_FILES instead of
2109 *.doc, so that rebuilding it works.
2111 Wed Mar 15 08:12:14 2000 Greg J. Badros <gjb@cs.washington.edu>
2113 * libguile.h: Include libguile/validate.h. Thanks Keisuke Nishida!
2115 * guile-snarf.awk.in: Replace docstring line-ending \n" and \n\n"
2116 with nothing and \n, respectively. Thanks Keisuke Nishida for
2117 noticing this problem.
2119 2000-03-15 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2121 * __scm.h (GUILE_NEW_GC_SCHEME): Define this if you want to test a
2122 new way of allocating heap. It makes Guile fast, but still
2125 * gc.c, gc.h, pairs.h, init.c: Implementation of a new way of
2126 allocating heap. The basic idea is to trigger GC every Nth
2127 allocated cell and grow heap when free list runs out. The scheme
2128 has been extended so that GC isn't triggered until all remaining
2129 cells are used. The implementation is also prepared for
2130 development in the direction of POSIX threads.
2132 * gc.c (SCM_EXPHEAP): In order to grow by a factor of 1.5,
2133 SCM_EXPHEAP should return half of the heap size.
2135 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2137 The following change to init.c is only enabled if Guile was
2138 configured with --enable-guile-debug.
2140 * init.c (scm_i_getenv_int): New function.
2141 (scm_boot_guile_1): Use the environment variables
2142 GUILE_INIT_HEAP_SIZE, GUILE_INIT_HEAP_SIZE2 to select heap size if
2143 they exist. (This may be replaced by a Scheme level mechanism in
2146 * objprop.c (s_scm_set_object_property_x): Use scm_assq instead of
2147 scm_assoc. (Thanks to Keisuke Nishida.)
2149 2000-03-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2151 * eval.c, lang.c, lang.h (scm_lisp_nil, scm_lisp_t): Renamed from
2152 scm_nil, scm_t. (Thanks to Keisuke Nishida.)
2154 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2156 * init.c (scm_boot_guile_1): Use same initial segment size for
2157 1-word and 2-word segments. Having the smaller size causes Guile
2158 to GC too often. Obviously something needs to be done to allow
2159 for a smaller 2-word segment without this to happen. (The amount
2160 of heap for each type should be automatically adapted to the
2161 application somehow.)
2163 [Almost all of these changes should be documented in the NEWS
2166 * gc.h (scm_freelist_t): New type.
2168 * pairs.h (SCM_NEWCELL, SCM_NEWCELL2): Use new style freelists.
2170 * gc.c (SCM_INIT_HEAP_SIZE): Changed from 32768 --> 40000 so that
2171 all of Guile basics fits into one segment and there suitable room
2173 (SCM_EXPHEAP): Now takes an argument. Grow by a factor of 1.5
2175 (scm_freelist, scm_freelist2): Now of type scm_freelist_t.
2176 Freelists now contains information about object span, cells
2177 collected and amount of cells in heap segments belonging to the
2179 (scm_heap_size, scm_gc_cells_collected): Removed.
2181 * init.c (scm_boot_guile_1): Make 2-word segment 8K (512 cells).
2183 * Makefile.am (libguile_la_LDFLAGS): Bumped library version
2186 * __scm.h eq.c, eval.c, gc.c, gc.h, gh_data, hash.c, numbers.c,
2187 numbers.h, objects.c, ramap.c, random.c, unif.c, unif.h: Extensive
2188 rewrite of handling of real and complex numbers.
2189 (SCM_FLOATS, SCM_SINGLES): These #ifdef conditionals have been
2190 removed along with the support for floats. (Float vectors are
2193 * tags.h (scm_tcs_bignums): Removed.
2194 (scm_tc16_bigpos, scm_tc16_bigneg): Replaced by scm_tc16_big.
2195 Use SCM_BIGSIGN(x) to test for sign!
2196 (scm_tc16_big): The new bignum type.
2197 (SCM_REAL_PART, SCM_IMAG_PART): Removed.
2199 * numbers.h (SCM_BIGSIGN): Sign moved to bit 16.
2200 (scm_makdbl): Deprecated.
2201 (SCM_NEWREAL, SCM_NEWCOMPLEX): New macros.
2202 (SCM_SINGP): Deprecated.
2204 (SCM_INEXP, SCM_CPLXP): Deprecated.
2205 (SCM_INEXACTP, SCM_COMPLEXP): New macros.
2206 (SCM_COMPLEX_REAL, SCM_COMPLEX_IMAG): Renamed from
2207 SCM_REAL, SCM_IMAG (and now only valid for complex numbers).
2208 (SCM_REAL, SCM_IMAG): New, *deprecated*, selectors which work both
2209 for doubles and complex numbers.
2210 (SCM_REAL_VALUE): New selector for doubles.
2211 (scm_double_t, scm_complex_t): New types.
2214 * numbers.c (scm_floprint, scm_floequal): Removed.
2215 (scm_print_real, scm_print_complex, scm_real_equalp,
2216 scm_complex_equalp): New functions.
2218 * unif.c (scm_makflo): Removed.
2220 * smob.h (SCM_SMOB_PREDICATE): New macro.
2221 (SCM_NEWSMOB2, SCM_RETURN_NEWSMOB2, SCM_NEWSMOB3,
2222 SCM_RETURN_NEWSMOB3): New macros.
2224 1999-11-21 Michael Livshin <mlivshin@bigfoot.com>
2226 The following changes implement primitive support for double cells
2227 (i.e. four-word cells) and change the representation of some
2228 things to multi-cells instead of cons+malloc. (Applied and
2231 * pairs.h (SCM_NEWCELL2): double-cell variants of SCM_NEWCELL.
2232 (SCM_CELL_WORD, SCM_CELL_WORDLOC, SCM_SET_CELL_WORD): primitive
2233 multi-cell access macros (used by the ones below).
2234 (SCM_CELL_WORD[0-3], SCM_SET_CELL_WORD[0-3]): multi-cell access
2237 * gc.c (scm_freelist2): multi-cell freelists.
2238 (inner_map_free_list): map_free_list, parameterized on ncells.
2239 "nn cells in segment mm" was misleading for ncells > 1; changed to
2240 "objects". still print cells too, though.
2241 (scm_map_free_list): rewritten using inner_map_free_list.
2242 (scm_check_freelist): get freelist as parameter, since now we have
2244 (scm_debug_newcell2): multi-cell variants of
2246 (scm_gc_for_newcell): take ncells and freelist pointer as
2248 (scm_gc_mark): add case for tc7_pws (procedures with setters are
2250 (scm_gc_sweep): don't free the float data, since it's not malloced
2252 (init_heap_seg): didn't understand what n_new_objects stood for,
2253 so changed to n_new_cells.
2254 (make_initial_segment): new function, makes an initial segment
2255 according to given ncells.
2256 (scm_init_storage): call make_initial_segment, for ncells={1,2,3}.
2258 * numbers.c (scm_makdbl): no malloc'ing needed, so the
2259 {DEFER,ALLOW}_INTS thing removed.
2261 * numbers.h (struct scm_dbl): changed to represent a double cell,
2262 with the number in the second half.
2264 * dynwind.c: changed the wind-guards representation to double
2267 * procs.c, procs.h: changed the procedure-with-setter representation
2270 * async.c, async.h: made async representation a double cell.
2272 * dynl.c: made dynamic_obj representation a double cell.
2274 2000-03-13 Gary Houston <ghouston@arglist.com>
2276 * ports.c (flush_void_port): renamed to flush_port_default.
2277 (end_input_void_port): renamed to end_input_default.
2279 * init.c (scm_standard_stream_to_port): create a void port instead
2280 of opening /dev/null if the standard file descriptors are bad.
2281 advantages: no portability problems, doesn't waste a file descriptor,
2282 simplifies the code (thanks to Marius for the idea).
2284 * vports.c (s_scm_make_soft_port): call scm_port_non_buffer.
2286 * void ports: make reading from a void port give EOF instead of
2288 * ports.c (s_scm_sys_make_void_port): modified docstring.
2289 (fill_input_void_port): new proc.
2290 (scm_init_ports): set up fill_input_void_port.
2291 * ports.c (scm_port_non_buffer): new proc.
2292 (scm_void_port): call scm_port_non_buffer.
2294 * fports.c (scm_setvbuf): docstring: remove the fcntl documentation
2295 which was incorrectly appended.
2297 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2299 * guile-doc-snarf.in: Don't use absolute path for `sed'. (Note
2300 that we can't use autoconf for this. Autoconf itself relies on
2301 the existence of `sed' somewhere on your path.) (Thanks to Dirk
2304 2000-03-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2306 * Makefile.am (libguile_la_SOURCES): Moved iselect.c here from
2307 EXTRA_libguile_la_SOURCES.
2309 * iselect.h: Always declare scm_internal_select.
2311 * iselect.c (scm_internal_select): Added SCM_ASYNC_TICK at the
2312 end. Also let scm_internal_select be a real function also when
2315 * __scm.h (SCM_TICK): Oops! Forgot to put SCM_ASYNC_TICK here...
2317 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2319 * __scm.h (SCM_ALLOW_INTS, SCM_REALLOW_INTS): Removed call to
2320 SCM_ASYNC_TICK. (This is a preparation for POSIX threads support,
2321 and kind of an experiment: Will this cause problems?)
2323 Sun Mar 12 13:26:30 2000 Greg J. Badros <gjb@cs.washington.edu>
2325 * Makefile.am: Added *.doc to DISTCLEANFILES.
2327 2000-03-12 Gary Houston <ghouston@arglist.com>
2329 * fports.c (scm_fdes_to_port): call fcntl F_GETFL to test that
2330 the fdes is valid before doing anything else. check that
2331 the file descriptor supports the modes required.
2332 (scm_fport_buffer_add): don't throw an error if fstat doesn't
2333 work: just use the default buffer size.
2335 * throw.c: change an outdated comment about scm_internal_catch
2336 BODY: it doesn't take a jumpbuf arg.
2338 * init.c (scm_standard_stream_to_port): install a handler in case
2339 scm_fdes_to_port throws an error. don't check here whether the
2340 file descriptor is valid, since scm_fdes_to_port will do that.
2341 set the revealed count depending on whether the port got the
2342 standard file descriptor.
2343 (stream_body_data): new type.
2344 (stream_body, stream_handler): new procs.
2346 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2348 * stacks.c, stacks.h, struct.c, tags.h, unif.c (scm_bits_t):
2349 Renamed from SCMWORD.
2351 * tags.h (SCM_NCELLP): Removed (SCMWORD).
2353 * arbiters.c (SCM_ARB_LOCKED): Use SCM_UNPACK_CAR.
2355 * async.c, boolean.h, debug.c, dynl.c, dynwind.c, eval.c, eval.h,
2356 feature.h, filesys.h, fluids.h, fports.c, fports.h, gc.c, gc.h,
2357 hash.c, keywords.h, macros.c, numbers.c, numbers.h, objects.c,
2358 objects.h, options.c, pairs.h, ports.c, ports.h, print.c,

2361 throw.c, unif.c, unif.h, variable.h, vectors.h, weaks.c,
2362 weaks.h (SCM_PACK, SCM_UNPACK, SCM_UNPACK_CAR): Renamed from
2363 SCM_ASSCM, SCM_ASWORD, SCM_CARW).
2365 * numbers.h (SCM_SRS, SCM_INUM): Corrected SCM_ASSCM/ASWORD fixes.
2367 * alist.c, eval.c, net_db.c, posix.c, print.c, snarf.h, struct.c,
2368 tags.h: Fixed copyright notices.
2370 * struct.c, coop-threads.c: SCM_ASSCM/ASWORD fixes.
2372 2000-03-12 Marius Vollmer <mvo@zagadka.ping.de>
2374 * init.c (scm_standard_stream_to_port): Check whether the file
2375 descriptor is valid and substitute "/dev/null" when not.
2377 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2379 * coop-defs.h (struct timespec): Conditionally defined.
2381 * coop.c (coop_condition_variable_timed_wait_mutex): Use ETIMEDOUT
2384 * readline.c (match_paren): Bugfix: First arg to select is not
2385 number of descriptors but the number of the highest descriptor +
2388 This is a preliminary attempt at a cleanup of the threads support
2389 code. It moves things to better places, makes arguments more
2390 consistent with the POSIX API (which is used in GNOME's glib), and
2391 adds new functionality.
2393 * readline.c (scm_init_readline): Added new arg to scm_init_mutex.
2395 * coop-defs.h (scm_mutex_trylock): New macro: alias for
2397 (scm_cond_init): Changed definition to
2398 coop_new_condition_variable_init.
2400 * coop.c: #include <errno.h>
2401 (coop_timeout_qinsert): Moved here from iselect.c
2402 (coop_new_mutex_init, coop_new_condition_variable_init): New
2403 functions. The strange names are temporary. Use scm_mutex_init
2404 and scm_cond_init instead.
2405 (coop_mutex_trylock): New function. Uses errno.h:EBUSY. errno.h
2406 is ANSI C, but should we check for individual error codes in
2408 (coop_condition_variable_timed_wait_mutex): New function.
2409 (coop_key_create, coop_setspecific, coop_getspecific,
2410 coop_key_delete): New functions.
2412 * iselect.c (coop_timout_qinsert): Moved to coop.c
2414 2000-03-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2416 * pairs.h (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR,
2417 SCM_SETOR_CDR): Corrected SCM_ASSCM/WORD fixes.
2419 * tags.h (SCM_VOIDP_TEST): Renamed from VOIDP_TEST.
2422 * objects.h (SCM_CLASS_FLAGS, SCM_OBJ_CLASS_FLAGS,
2423 SCM_SET_CLASS_INSTANCE_SIZE), struct.h (SCM_STRUCT_VTABLE_DATA),
2424 proc.h (SCM_CLOSCAR): SCM_ASSCM/WORD fixes.
2426 * eval.c (scm_lookupcar1): Inserted SCM_ASWORD in expressions
2429 2000-03-11 Dale P. Smith <dpsm@en.com>, applied by Greg J. Badros, <gjb@cs.washington.edu>
2431 * numbers.c (scm_copy_big_dec, scm_copy_smaller, scm_big_ior,
2432 scm_big_xor, scm_big_and, scm_big_test): Added new lowlevel bignum
2433 logical functions from SCM.
2435 (logand, logior, logxor, logtest, logbit?): Extended scheme
2436 logical functions to use bignums from SCM.
2438 (lognot): Removed call to `SCM_VALIDATE_INUM' that prevented
2439 lognot from using bignums.
2441 Thu Mar 9 11:33:25 2000 Greg J. Badros <gjb@cs.washington.edu>
2443 * vectors.h (SCM_VELTS_AS_STACKITEMS): Added this macro to help in
2444 eliminating some warnings.
2446 * unif.c, strports.c, print.c, options.c: Fix some warnings on
2449 * gc.c, gc.h: Added scm_return_first_int(), and added comment re:
2450 what the scm_return_first* functions do.
2452 2000-03-09 Han-Wen Nienhuys <hanwen@cs.uu.nl>, applied by Greg J. Badros, <gjb@cs.washington.edu>
2454 * libguile/*.[ch]: make a distinction between SCM as a generic
2455 name for a Scheme object (now a void*), and SCM as 32 bit word for
2456 storing tags and immediates (now a long int). Introduced
2457 SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious
2458 code in the process: arbiter.c (use macros), unif.c (scm_array_p),
2460 Wed Mar 8 10:15:59 2000 Greg J. Badros <gjb@cs.washington.edu>
2462 * numbers.c: Use SCM_VALIDATE_LONG_COPY, and longs, not ints, in
2463 various logXXX primitives. Thanks Eric Moore!
2465 Tue Mar 7 08:05:22 2000 Greg J. Badros <gjb@cs.washington.edu>
2467 * run-test, remaining-docs-needed: Added these scripts. The
2468 second one is only temporary until the docstring additions are
2469 complete. run-test may best live on, but is here mostly for
2470 convenience and awareness for now.
2472 * hash.c: Docs, minor cleanup patch from Dirk Herrman.
2474 Thu Mar 2 16:06:58 2000 Greg J. Badros <gjb@cs.washington.edu>
2476 * error.h, error.c: Added `scm_wrong_type_arg_msg' to support
2477 displaying the expected type. Use SCM_LISTn in a couple places
2478 instead of scm_cons-ing by hand.
2480 * __scm.h: Added SCM_ASSERT_TYPE macro.
2482 * validate.h, scm_validate.h: Added the former, as a renamed
2483 version of the latter with SCM_ASSERT_TYPE used in
2484 SCM_MAKE_VALIDATE (instead of just SCM_ASSERT)
2486 * Makefile.am: Rename scm_validate.h to validate.h.
2488 * *.c, *.h: Include validate.h, not scm_validate.h (old name's
2489 prefix was superfluous).
2491 Thu Mar 2 15:33:12 2000 Greg J. Badros <gjb@cs.washington.edu>
2493 * hashtab.c: Improved documentation for lots of functions. Added
2494 handwritten docs for `hash-fold'.
2496 Thu Mar 2 15:13:25 2000 Greg J. Badros <gjb@cs.washington.edu>
2498 * list.c: Added hand-written docs for `del{q,v,ete}1!'.
2500 Thu Mar 2 12:38:30 2000 Greg J. Badros <gjb@cs.washington.edu>
2502 * list.c: Moved append docs to append! Thanks Dirk Hermann. Also,
2503 added append docs from R4RS.
2505 * strings.c: Docstring typo fix, + eliminate unneeded IMP tests.
2506 Thanks Dirk Hermann!
2508 * chars.h: Provide SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR and
2509 deprecate SCM_ICHRP, SCM_ICHR, SCM_MAKICHR. Thanks Dirk Hermann!
2511 * *.h, *.c: Use SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR throughout.
2512 Drop use of SCM_P for function prototypes... assume an ANSI C
2513 compiler. Thanks Dirk Hermann!
2515 Sat Feb 19 12:20:12 2000 Greg J. Badros <gjb@cs.washington.edu>
2517 * ports.c: Made `set-port-column!' and `set-port-line!' each
2518 return SCM_UNSPECIFIED instead of a (not-scheme-object) integer
2519 that caused a seg fault. Also fixed `set-port-column!'s
2520 docstring. Thanks Han-Wen Nienhuys for finding the bug!
2522 Sun Feb 13 19:11:42 2000 Greg J. Badros <gjb@cs.washington.edu>
2524 * arbiters.c, eq.c, gc.c, guardians.c, list.c, ports.c, print.c,
2525 regex-posix.c, scmsigs.c, stime.c, strings.c, variable.c, stime.c,
2526 strings.c, variable.c: Added lots of documentation, cleaned up
2527 some existing documentation. Occasionally changed formal params
2528 to match docs. Also folded an #ifdef into the inners of a
2529 primitive instead of having two copies of the primitive
2530 (`get-internal-real-time', from stime.c)
2532 Sun Feb 13 18:12:19 2000 Greg J. Badros <gjb@cs.washington.edu>
2534 * ports.c: Added docs for primitives missing them. Written by
2537 Sun Feb 13 09:40:36 2000 Greg J. Badros <gjb@cs.washington.edu>
2539 * guile-doc-snarf.in: Use ${AWK} -f guile-func-name-check, not
2540 just execing guile-func-name-check. Thanks Michael Livshin!
2542 Thu Feb 10 11:43:23 2000 Greg J. Badros <gjb@cs.washington.edu>
2544 * guile-snarf.awk.in: Tweak to work with Sun/HP awk, removed some
2545 dead code. Patch from Michael Livshin.
2547 * guile-doc-snarf.in: Tweak to work with Sun/HP sh. Patch from
2550 2000-02-09 Gary Houston <ghouston@arglist.com>
2552 * init.c (scm_init_standard_ports): when stdout is a tty, make the
2553 current-output-port unbuffered by default. this is less confusing
2554 for interactive use. it was line-buffered because of a
2555 performance problem with unbuffered ports, but I think it will be
2558 2000-02-08 Gary Houston <ghouston@arglist.com>
2560 * __scm.h: don't define long_long or ulong_long if HAVE_LONG_LONGS
2563 * stime.c (scm_localtime, scm_mktime): if neither HAVE_TM_ZONE nor
2564 HAVE_TZNAME are defined, use an empty string instead of giving two
2565 spurious compile-time errors.
2567 Tue Feb 8 13:57:46 2000 Greg J. Badros <gjb@cs.washington.edu>
2569 * ports.c: Doc patches from Richard Kim. Pasted from MIT Scheme.
2572 Mon Feb 7 09:07:31 2000 Greg J. Badros <gjb@cs.washington.edu>
2574 * macros.c: Doc patches from Richard Kim. Pasted from scm.texi.
2576 Sun Feb 6 20:26:21 2000 Greg J. Badros <gjb@cs.washington.edu>
2578 * pairs.c: Doc patches from Richard Kim. Pasted from MIT Scheme
2579 (which is GNU GPL'd).
2581 2000-01-31 Gary Houston <ghouston@arglist.com>
2583 * strings.h: don't use SCM_P. don't include <string.h>.
2584 * error.c, gh_data.c, ports.c, script.c, strop.c: include <string.h>.
2586 * strings.c (scm_string_ref): make the 2nd argument compulsory.
2587 previously it defaulted to zero for no good reason that I can see.
2588 use a local variable for SCM_INUM (k). replace
2589 SCM_VALIDATE_INUM_DEF with SCM_VALIDATE_INUM_COPY.
2591 (scm_makfromstr): cosmetic changes.
2593 (scm_string): Accept only chars in the list, not strings, for
2594 conformance to R5RS (particularly for list->string, which is
2595 supposed to be the inverse of string->list.) remove
2596 SCM_DEFER_INTS/SCM_ALLOW_INTS, which is unnecessary since
2597 scm_makstr handles the cell allocation. when reporting wrong-type
2598 arg, don't report the position as 1.
2600 * posix.c (scm_init_posix): intern PIPE_BUF if it's defined.
2602 2000-01-29 Gary Houston <ghouston@arglist.com>
2604 * posix.c (scm_pipe): rewrote the docstring.
2606 * filesys.c (scm_select, retrieve_select_type, get_element,
2607 fill_select_type, set_element): modified so that Scheme
2608 "select" tests port buffers for the ability to provide input
2609 or accept output. Previously only the underlying file descriptors
2610 were checked. Rewrote the docstring.
2612 Thu Jan 27 10:14:25 2000 Greg J. Badros <gjb@cs.washington.edu>
2614 * vectors.c, symbols.c, strorder.c: Documentation cut and pasted
2615 from Gregg Reynolds. Thanks Gregg!
2617 Thu Jan 27 09:59:38 2000 Greg J. Badros <gjb@cs.washington.edu>
2619 * strop.c (scm_i_index): Obfuscated commented-out SCM_DEFINE by
2620 adding "x" prefix to the line so that guile-func-name-check
2621 doesn't complain unnecessarily.
2623 Wed Jan 26 17:33:52 2000 Greg J. Badros <gjb@cs.washington.edu>
2625 * throw.c: Factor out an #ifdef/#else/#endif choice more finely
2626 for maintainability.
2628 * strop.c: Documentation added by Gregg A. Reynolds. Pasted in
2631 Wed Jan 26 10:02:11 2000 Greg J. Badros <gjb@cs.washington.edu>
2633 * tag.c: Added doc for `tag', but mark as deprecated since Mikael
2634 suggests removing tag.c altogether (and using a new `class-of'
2637 * strings.c: Added documentation from Gregg A. Reynolds. Edited
2638 a bit by me to use FOO instead of @var{foo} and to have the
2639 summary come before preconditions on input. Also dropped trailing
2642 * gsubr.c: Do not use SCM_DEFINE for `gsubr-apply'. Register the
2643 function with scm_make_subr_opt w/ last arg of 0 so it is not
2644 visible at the Scheme level. Mikael says that this is the right
2645 thing because the first arg to the proc is the guts of a compiled
2646 closure and shouldn't be exposed to the Scheme level.
2648 Tue Jan 25 17:15:47 2000 Greg J. Badros <gjb@cs.washington.edu>
2650 * sort.c: typo in comment fixed.
2652 * keywords.c: Added documentation.
2654 * guardians.c: Added documentation (could be better).
2656 * gc.c: Added docs for gc-set-debug-check-freelist.
2658 * eq.c: Added docs for eq?, eqv? equal? abridged from R4RS.
2660 * boolean.c: Added docs for `not', `boolean?' (by hand).
2662 Tue Jan 25 13:28:56 2000 Greg J. Badros <gjb@cs.washington.edu>
2664 * random.c: Added documentation, from SLIB page:
2665 http://angela.ctrl-c.liu.se/~calle/scheme/slib_toc.html
2667 Mon Jan 24 17:50:20 2000 Greg J. Badros <gjb@cs.washington.edu>
2669 * variable.c, version.c: Added documentation, written by hand
2670 since I could not find anything already written that was
2673 2000-01-23 Gary Houston <ghouston@arglist.com>
2675 * filesys.c (scm_chown): omit port/fdes support if HAVE_FCHOWN is
2676 not defined (thanks to Richard Y. Kim).
2678 Thu Jan 20 13:00:38 2000 Greg J. Badros <gjb@cs.washington.edu>
2680 * Makefile.in: Removed, this is auto-generated.
2682 Thu Jan 20 11:33:47 2000 Dirk Hermann <dirk@ida.ing.tu-bs.de> --applied 01/20/00 gjb
2684 * list.c: Put some variable initialization code at the point of
2685 declaration; Added a comment for list*; Formatting changes.
2687 * load.c: use SCM_NNULLP to make sure the end of a list is not
2690 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2692 * backtrace.c (scm_display_error_message): Bugfix: Don't use
2693 result of scm_list_p as C boolean.
2694 (scm_display_error_message, scm_set_print_params_x): Use new
2695 validation macros. (Thanks to Dirk Herrmann.)
2697 * net_db.c (scm_resolv_error): Cast result from hstrerror.
2699 * strports.c (st_end_input): Inserted parenthesis to get operator
2702 * list.h (scm_init_list): Removed SCM_P around prototypes.
2704 * fports.c, list.c, numbers.c, ports.c, stime.c, symbols.c,
2705 filesys.c, posix.c: Converted docstrings to ANSI C format and
2706 escaped " occurring inside string literals.
2708 Tue Jan 18 13:21:08 2000 Mikael Djurfeldt <mdj@r11n07-s.pdc.kth.se>
2710 * posix.c (scm_mknod): Escape " occuring inside docstring.
2712 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2714 * alist.c, chars.c, debug.c, dynl.c, dynwind.c, error.c, eval.c,
2715 evalext.c, filesys.c, gc.c, hash.c, hashtab.c, ioext.c,
2716 keywords.c, list.c, load.c, macros.c, net_db.c, numbers.c,
2717 objprop.c, ports.c, posix.c, print.c, procprop.c, procs.c,
2718 ramap.c, regex-posix.c, root.c, scmsigs.c, simpos.c, socket.c,
2719 stacks.c, stime.c, strings.c, strop.c, strports.c, struct.c,
2720 symbols.c, throw.c, unif.c, vectors.c, version.c, vports.c,
2721 weaks.c: Converted docstrings to ANSI C format.
2723 * filesys.c (scm_chmod), simpos.c (scm_system), version
2724 (scm_version), vports (scm_make_soft_port): Escape " occuring
2727 Mon Jan 17 11:41:22 2000 Greg J. Badros <gjb@cs.washington.edu>
2729 * scm_validate.h: Added SCM_VALIDATE_ULONG_COPY,
2730 SCM_VALIDATE_LONG_COPY
2732 * numbers.c: Use SCM_VALIDATE_ULONG_COPY, instead of
2733 SCM_VALIDATE_INUM_COPY to let bigger numbers be used. Rename a
2734 couple of formal arguments (and fix their uses) to make arguments
2735 match the documentation.
2737 2000-01-14 <mstachow@alum.mit.edu>
2739 * Makefile.am: Augment path when running guile-doc-snarf so
2740 guile-func-name-check is found.
2742 Fri Jan 14 09:34:55 2000 Greg J. Badros <gjb@cs.washington.edu>
2744 * scm_validate.h (SCM_NUM2LONG_DEF): Fix this macro to just use
2745 def, not SCM_MAKINUM(def); thanks Janis Bzerins!
2747 Wed Jan 12 00:06:53 2000 Greg J. Badros <gjb@cs.washington.edu>
2749 * net_db.c (s_scm_inet_makeaddr): Use SCM_NUM2ULONG since that's
2750 the way guile-1.3.4 worked, but #if 0 out the version using
2751 SCM_VALIDATE_INUM_COPY for stricter testing.
2753 Tue Jan 11 18:24:18 2000 Greg J. Badros <gjb@cs.washington.edu>
2755 * guile-doc-snarf.in: Use new $fullfilename for running
2756 guile-func-name-check, and put "$fullfilename" and "$filename" in
2757 quotes at uses to make sure re-splitting on whitespace does not
2758 occur (so filenames w/ embedded whitespace would work okay, though
2759 I sure hope we never have to deal with that! :-) ). Thanks to
2760 Mikael for pointing out the source_dir != build_dir was broken.
2762 Tue Jan 11 17:42:40 2000 Greg J. Badros <gjb@cs.washington.edu>
2764 * scm_validate.h: Added SCM_NUM2LONG_DEF macro. Make
2765 SCM_OUT_OF_RANGE use SCM_MAKINUM, not scm_long2num. Added
2766 SCM_COERCE_ROSTRING macro. Added SCM_VALIDATE_NONEMPTYLIST
2767 macro. Fix SCM_VALIDATE_STRINGORSUBSTR macro to not use SLOPPY
2770 * ports.c (scm_port_closed_p): Validate that the arg is a PORT,
2771 then return whether it's an open port (was validating that it was
2772 an open port -- this was a bug I introduced back in December, but
2773 my careful reading of diffs caught it).
2775 * numbers.c: Recombine the two conditional-compilation paths for
2776 all the log* primitives -- they were split based on #ifndef
2777 scm_long2num; factored out a SCM_LOGOP_RETURN macro, and fixed
2778 some bugs and inconsistencies in the two sets of implementations.
2779 (scm_lognot) Fixed *atrocious* re-use of a SCM as an integer!
2781 * ioext.c: Use SCM_ASSERT_RANGE in a couple places, and
2782 SCM_VALIDATE_INUM_COPY once where it should've been used.
2784 * fluids.c (scm_internal_with_fluids): Use
2785 SCM_VALIDATE_LIST_COPYLEN.
2787 * filesys.c: Use SCM_NUM2LONG instead of SCM_VALIDATE_INUM_COPY;
2788 this is questionable as it relaxes type safety, but other changes
2789 were useful and all SCM_NUM2LONG's should probably be
2790 revisited. Use SCM_OUT_OF_RANGE, SCM_WRONG_TYPE_ARG.
2792 * evalext.c: line-break change on 1 line.
2794 * eval.c (nconc2last): Takes a non-empty list as its first
2795 argument, not just a list.
2797 * dynl.c: Use new SCM_COERCE_ROSTRING macro.
2799 Tue Jan 11 15:44:23 2000 Greg J. Badros <gjb@cs.washington.edu>
2801 * dynl.c, feature.c, filesys.c, fports.c, list.c, load.c,
2802 net_db.c, sort.c, stacks.c, unif.c: Use SCM_WTA, SCM_MISC_ERROR
2805 * symbols.c (scm_sysintern0): Fixed the function name in a
2806 scm_misc_error invocation.
2808 * print.c (scm_simple_format): Do not need SCM_COERCE_SUBSTR, and
2809 use scm_return_first to ward off latent GC bug that Mikael caught.
2811 * async.c: Use SCM_VALIDATE_ASYNC_COPY one place where it wasn't
2812 used before but should've been.
2814 2000-01-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2816 * snarf.h (SCM_PROC1): Replaced SCM (*) (...) with
2817 SCM_FUNC_CAST_ARBITRARY_ARGS.
2819 Tue Jan 11 13:44:07 2000 Greg J. Badros <gjb@cs.washington.edu>
2821 * guile-func-name-check.in: Added this script to statically check
2822 #define FUNC_NAME, #undef FUNC_NAME in the source.
2824 * sort.c, posix.c: Fix #undef FUNC_NAME lines to not have trailing
2825 redundant comment, semicolon; caught by new guile-func-name-check
2828 * debug.c: Fix mistaken #define FUNC_NAME for scm_make_iloc.
2829 Caught by new guile-func-name-check-script.
2831 * Makefile.am: Added guile-func-name-check to bin_SCRIPTS
2833 * ramap.c: Fix #if 0'd out code to be syntactically acceptable to
2834 guile-func-name-check.
2836 * guile-doc-snarf.in: Run guile-func-name-check on the file before
2839 Tue Jan 11 11:31:10 2000 Greg J. Badros <gjb@cs.washington.edu>
2841 * fports.c, ports.c, ports.h, strports.c, vports.c: Make write
2842 port function take const void*, not void*.
2844 Tue Jan 11 11:18:07 2000 Greg J. Badros <gjb@cs.washington.edu>
2846 * scm_validate.h, chars.c, ports.c, print.c, read.c, strings.c,
2847 strop.c: Use SCM_VALIDATE_ICHR, SCM_VALIDATE_ICHR_COPY instead of
2848 SCM_VALIDATE_CHAR, SCM_VALIDATE_CHAR_COPY. Change made for
2849 consistency with the other macros dealing with immediate
2850 characters. (Similar to INT -> INUM change a week or so ago).
2852 Tue Jan 11 10:41:46 2000 Greg J. Badros <gjb@cs.washington.edu>
2854 * dynl.c, error.c, eval.c, feature.c, filesys.c, fports.c, list.c, load.c,
2855 net_db.c, read.c, socket.c: Update error messages to use ~A for
2856 %s, ~S for %S to work with new `simple-format' format and be
2857 standardized better.
2859 * print.h, print.c (scm_simple_format): Added `simple-format'
2860 primitive. It's the old scm_display_error, with ARGS now a rest
2861 parameter, and the destination first instead of last (and a couple
2862 new capabilities inspired by `format' -- #t as destination means
2863 current-output-port, #f means return the formatted text as a
2866 * gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
2868 * backtrace.c (scm_display_error_message): Rewrote to use
2869 scm_simple_format() procedure.
2871 * __scm.h: Added commented-out #define of GUILE_DEBUG_FREELIST
2873 2000-01-09 Marius Vollmer <mvo@zagadka.ping.de>
2875 Finally applied the libltdl patch from Thomas Tanner, with slight
2878 * DYNAMIC-LINKING: Removed because it is obsolete.
2879 * dynl.c: Use ANSI prototypes.
2880 (sysdep_dynl_link): Use lt_dlopenext instead of lt_dlopen.
2881 * scmconfig.h.in: Do not change, as it is automatically generated.
2883 1999-07-25 Thomas Tanner <tanner@ffii.org>
2885 * dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c: deleted
2887 * Makefile.am: likewise, add INCLTDL (libltdl headers) to
2888 INCLUDES, set dlpreopened files in LDFLAGS, link libguile
2890 * dynl.c: use libltdl if DYNAMIC_LINKING is enabled,
2891 * guile.c: register preloaded modules
2892 * scmconfig.h.in: remove obsolete symbols
2894 2000-01-09 Gary Houston <ghouston@arglist.com>
2896 * These changes should make it unnecessary to call tzset from
2897 Scheme after modifying the TZ environment variable, even if the
2898 system date facilities cache the value.
2899 * stime.c (setzone, scm_localtime): added comments.
2900 (tzset): don't define a noop tzset macro if HAVE_TZSET not defined.
2901 (setzone): don't call tzset.
2902 (restorezone): call tzset only if HAVE_TZSET is defined.
2903 (scm_tzset): don't define if HAVE_TZSET not defined. Change the
2904 doc string to indicate that this procedure isn't likely to do
2906 (scm_localtime, scm_strftime, scm_mktime): call tzset if
2907 LOCALTIME_CACHE is defined.
2909 2000-01-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2911 * posix.c (scm_sync): Return SCM_UNSPECIFIED.
2913 2000-01-09 Gary Houston <ghouston@arglist.com>
2915 * eval.c: define scm_unbound_variable_key ('unbound-variable).
2916 scm_lookupcar1: throw an error with key 'unbound-variable instead
2917 of 'misc-error when an unbound variable is encountered.
2919 * filesys.c (scm_mkdir, scm_rmdir, scm_getcwd, scm_select,
2920 scm_symlink, scm_readlink, scm_lstat),
2921 posix.c (scm_setpgid, scm_setsid, scm_ctermid, scm_tcgetpgrp,
2922 scm_tcsetpgrp, scm_uname, scm_setlocale, scm_mknod, scm_nice,
2924 simpos.c (scm_system),
2925 stime.c (scm_times, scm_strptime):
2926 move the HAVE_XXX feature tests out of the procedure bodies.
2927 don't use SCM_SYSMISSING.
2928 scm_validate.h (SCM_SYSMISSING): removed.
2929 error.h, error.c (scm_sysmissing): comment that this is deprecated.
2930 see ChangeLog entry for 1999-12-28.
2932 Sat Jan 8 19:52:04 2000 Greg J. Badros <gjb@cs.washington.edu>
2934 * scm_validate.h (SCM_VALIDATE_BOOL_COPY): Fix typo.
2936 Sat Jan 8 17:06:46 2000 Greg J. Badros <gjb@cs.washington.edu>
2938 * backtrace.c: Fix spelling typo in a comment.
2940 * snarf.h: Use new SCM_DOCS macro to encapsulate the non SCM_INIT
2941 text. Reformatted some of the expansions.
2943 Fri Jan 7 15:50:46 2000 Greg J. Badros <gjb@cs.washington.edu>
2945 * scm_validate.h (SCM_OUT_OF_RANGE): Use scm_out_of_range_pos to
2946 report the position of the argument.
2948 * error.h, error.c (scm_out_of_range_pos): Added this function to
2949 take extra "pos" argument, the position number of the errant
2952 * debug.c: Use SCM_OUT_OF_RANGE instead of scm_out_of_range.
2954 * snarf.h: Use SCM_HERE and SCM_INIT as names, not SCM_NOTSNARF
2955 and SCM_SNARFING. Also put the %%% in the SCM_INIT since Mikael
2956 prefers that and I'm reasonably indifferent.
2958 Fri Jan 7 15:03:32 2000 Greg J. Badros <gjb@cs.washington.edu>
2960 * snarf.h: Factor out differences between C++ and non-C++ into
2961 SCM_FUNC_CAST_ARBITRARY_ARGS macro. Modify all the snarf macro
2962 definitions to use SCM_NOTSNARF and SCM_SNARFING macros (like
2963 Mikael's macros, below, but changed names and SCM_SNARFING no
2964 longer expands to include %%% -- that must appear in the argument
2965 so that the token appears at the call-site as a reminder).
2967 2000-01-07 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2969 * snarf.h (SCM_INSITU, SCM_INIT): New snarf macros for use in user
2970 snarf macro definitions.
2972 2000-01-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2974 * chars.c (scm_integer_to_char): Use Greg's nice
2975 SCM_VALIDATE_INUM_RANGE macro for argument checking for closer
2978 Thu Jan 6 11:48:49 2000 Greg J. Badros <gjb@cs.washington.edu>
2980 * *.c, snarf.h: Replace GUILE_PROC1 with SCM_DEFINE1 throughout.
2982 Thu Jan 6 11:22:53 2000 Greg J. Badros <gjb@cs.washington.edu>
2984 * Makefile.am (ETAGS_ARGS): Switch to SCM_DEFINE, SCM_DEFINE1
2985 instead of GUILE_PROC.
2987 Thu Jan 6 11:21:49 2000 Greg J. Badros <gjb@cs.washington.edu>
2989 * alist.c: Do not report mismatch errors on some uses of `tmp' (do
2990 this by using SCM_ARG2 instead of `2' in the SCM_VALIDATE_CONS
2993 Thu Jan 6 09:54:33 2000 Dirk Herrmann <dirk@ida.ing.tu-bs.de> --gjb applied
2995 * scm_validate.h: Remove some redundant NIMP tests.
2997 * alist.c: minimize scope of the tmp variables, and initialize
2998 them when declared. The strange SCM_NIMP tests are replaced by
2999 SCM_CONSP tests that more closely reflect the intended semantics.
3000 However, we don't get a performance penalty here, because the
3001 SCM_CONSP test was performed by the ALISTCELL test anyway. * The
3002 extremely ugly use of ASRTGO macros was removed: The calls to
3003 ASRTGO were not encapsulated by "#ifndef SCM_RECKLESS", but got a
3004 label parameter that only exists when SCM_RECKLESS is not defined.
3005 This works, because ASRTGO itself is defined in a way that it only
3006 makes use of the label parameter if SCM_RECKLESS is not defined
3007 (shudder!). Does guile make at all use of the possibility to
3008 define SCM_RECKLESS? * Codesize is likely to be reduced, since
3009 instead of two calls to SCM_ASSERT performed by the ALISTCELL test
3010 we now only get one test.
3012 * list.c: Use SCM_NNULLP, not SCM_NIMP as appropriate. Also use
3013 SCM_NULLP instead of SCM_IMP. Drop use of "register" keyword on
3014 some variables in `list?'. Fix `reverse' and `reverse!'
3015 primitives to handle improper lists better.
3017 Wed Jan 5 11:24:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3019 * *.[ch]: Whitespace changes -- added space after SCM_VALIDATE_*
3020 macros and SCM_DEFINE macros to match GNU coding standards.
3022 Wed Jan 5 11:04:24 2000 Greg J. Badros <gjb@cs.washington.edu>
3024 * *.[ch]: Replace GUILE_PROC w/ SCM_DEFINE.
3026 Wed Jan 5 10:59:06 2000 Greg J. Badros <gjb@cs.washington.edu>
3028 * *.[ch]: Replace SCM_VALIDATE_INT w/ SCM_VALIDATE_INUM for
3029 better consistency with the names of other SCM_VALIDATE_ macros
3030 and better conformance to guile naming policy.
3032 Wed Jan 5 10:50:39 2000 Greg J. Badros <gjb@cs.washington.edu>
3034 * ports.c (s_scm_close_all_ports_except): Use SCM_ARG1 in a
3035 SCM_VALIDATE instead of 1 to avoid a check on the argument (since
3036 it's not the actual name of the formal).
3038 * guile-snarf.awk.in: Do argument/number mismatch checking and
3039 print warnings in an Emacs compile-mode parseable format.
3041 * struct.c: Use SCM_ASSERT_RANGE instead of SCM_ASSERT w/
3042 SCM_OUTOFRANGE as 3rd argument.
3044 * random.c: Fix argument/number mismatch (that I introduced :-( ).
3046 * __scm.h: Do not #define SCM_ARG* when snarfing;
3047 lets us distinguish between 1 and SCM_ARG1 when snarfing as only
3048 the former (using the number) requires the argument to match the
3049 formal in the current argument snarfing check.
3051 * snarf.h: Give new definition of SCM_ASSERT when in
3052 snarfing mode to output a lexically-identifiable sequence that the
3053 guile-snarf.awk script uses to verify argument/position matching.
3055 * ramap.c: Remove extraneous #undef FUNC_NAME.
3057 Wed Jan 5 08:36:38 2000 Greg J. Badros <gjb@cs.washington.edu>
3059 * guile-doc-snarf.awk.in: Removed -- guile-snarf.awk.in is the
3060 current version of the same functionality; it writes the .x output
3061 to stdout instead of directly into the file.
3063 Wed Jan 5 08:15:04 2000 Greg J. Badros <gjb@cs.washington.edu>
3065 * unif.c, symbols.c, strings.c, stacks.c, random.c, print.c,
3066 posix.c: Eliminated a bunch of SCM_NIMP(..)s that are now
3067 redundant with the safer macros. Patch from Dirk Hermann applied
3068 by hand. Thanks Dirk!
3070 * scm_validate.h: Added SCM_VALIDATE_VECTOR_OR_DVECTOR for some
3073 * ramap.c: whitespace change.
3075 Tue Jan 4 14:21:35 2000 Greg J. Badros <gjb@cs.washington.edu>
3077 * options.c, objects.c, keywords.c, gc.c: Some redundant SCM_NIMP
3078 removals from Dirk Hermann.
3080 * alist.c: Rename formals to match the parameter names in the
3081 documentation, updates to documentation. Thanks Dirk Hermann!
3083 2000-01-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3085 * eval.c (SCM_CEVAL): Reverse order of
3086 scm_stack_checking_enabled_p and SCM_STACK_OVERFLOW_P
3087 (Thanks to Brad Knotwell.)
3089 Mon Jan 3 08:30:02 2000 Greg Harvey <Greg.Harvey@thezone.net> (applied --01/03/00 gjb)
3091 * gc.c (scm_debug_newcell): Added SCM_SETCAR of the newly
3094 * pairs.h: Added a comment about the need for the SCM_SETCAR in
3097 Mon Jan 3 08:25:19 2000 Greg J. Badros <gjb@cs.washington.edu>
3099 * dynl-vms.c, debug.c, coop-threads.c, backtrace.c, eval.c: More
3100 SCM_NIMP tests that were redundant are now eliminated. Patches
3101 from Dirk Hermann applied by hand.
