1 2000-06-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
3 * gc.c (scm_unprotect_object): The reference count is guaranteed
4 to be a positive number.
6 2000-06-15 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
8 * eval.c: Updated comment above scm_map.
10 2000-06-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
12 * gc.c (scm_protect_object): Avoid looking up the object handle
14 (scm_unprotect_object): Abort if scm_unprotect_object is called on
15 an unprotected object.
17 2000-06-14 Michael Livshin <mlivshin@bigfoot.com>
19 * gc.c (scm_unprotect_object): fix a nasty typo bug (thanks to
22 2000-06-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
24 * socket.c (scm_getsockopt): Changed type for `optlen' from int to
26 (scm_accept, scm_getsockname, scm_getpeername, scm_recvfrom):
28 (scm_addr_buffer_size): Changed type from int to size_t.
30 * random.c: #include <string.h>. (Needed by memcpy.)
32 * guile-snarf.awk.in: Replace the dot_doc_file arg with "-",
33 indicating stdin, instead of "" and don't reset ARGC. This is a
34 workaround for `nawk' in AIX 4.3 on RS6000 but, as far as I know,
35 it is correct, and perhaps even better.
37 2000-06-14 Gary Houston <ghouston@arglist.com>
39 * scmsigs.c (scm_init_scmsigs): if HAVE_SIGINTERRUPT is not
40 defined, add SA_RESTART to the sigaction flags correctly
41 (thanks to Dale P. Smith).
43 2000-06-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
45 * strings.c: #include <string.h>. (Thanks to Bill Schottstaedt.)
47 * net_db.c (scm_resolv_error): Only use macro NETDB_INTERNAL if
48 defined. It isn't on sgi irix 5.3. (Thanks to Bill Schottstaedt.)
50 * Makefile.am (.c.doc): Pipe output (the .x contents) to /dev/null.
52 2000-06-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
54 * fports.c (scm_setvbuf): Use `free' instead of `scm_must_free'
55 since read and write buffers are allocated by `malloc'.
57 * Makefile.am: Removed old test code.
59 * gh_test_c.c, gh_test_repl.c: Removed.
61 2000-06-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
63 * iselect.c (SCM_NLONGBITS): Add workaround for the Sun 4.2
66 * inet_aton.c (inet_aton): Cast init value for `cp'.
68 * ramap.c (s_scm_array_fill_x): Cast `ve' properly in case
71 * symbols.c (scm_intern_obarray_soft,
72 scm_sysintern0_no_module_lookup): Cast `name' to unsigned char ptr
73 in calls to scm_strhash.
75 * strports.c (st_resize_port): Substituted SCM_UCHARS for
77 (st_write): Cast argument to strncpy to char ptr.
78 (scm_mkstrport): Substituted SCM_ROUCHARS for SCM_ROCHARS.
79 (scm_strport_to_string): Cast argument to scm_makfromstr to char
82 * ports.c (scm_ungetc): Cast value to unsigned char ptr before
83 storing in putback_buf.
84 (scm_unread_string): Substituted SCM_ROCHARS for SCM_ROUCHARS.
86 * ioext.c (s_scm_read_line): Cast result of call to
87 scm_do_read_line to unsigned char ptr.
89 * gdbint.c (SEND_STRING): Cast argument to char pointer.
91 * fports.c (fport_flush): Declare `ptr' as unsigned char (was
94 * Makefile.am (DOT_DOC_FILES): List doc-files explicitly. (We
95 shouldn't use Make rules which aren't supported by most Make
97 (OMIT_DEPENDENCIES): Defined to "libguile.h ltdl.h". (We don't
98 want these dependencies recorded, since they would get bogus
99 relative paths; libguile.h is only used in gh.h and guile.c.)
100 (EXTRA_DOT_X_FILES, EXTRA_DOT_DOC_FILES): New variables.
101 (guile-procedures.txt): Depend on EXTRA_DOT_DOC_FILES.
102 (modinclude_HEADERS): Removed kw.h.
104 * guile-snarf.in: Change regexp "^SCM__I" --> "^ *SCM__I".
105 (The preprocessor might insert spaces before the identifier.)
107 * snarf.h (SCM_SNARF_HERE, SCM_SNARF_INIT, SCM_SNARF_DOCS):
108 Renamed from SCM_HERE, SCM_INIT, SCM_DOCS.
110 * smob.h (scm_smobfuns): Removed deprecated type.
112 * smob.c, smob.h (scm_newsmob): Removed deprecated function.
113 (Replaced by `scm_make_smob_type'.)
115 * keywords.c (scm_tc16_kw): Removed deprecated type.
116 (Replaced by scm_tc16_keyword.)
118 * kw.h: Removed deprecated header file.
120 * evalext.c (serial-map): Removed deprected alias for scm_map.
121 (Has been replaced by `map-in-order'.)
123 * ramap.c (serial-array-copy!, serial-array-map!): Removed
124 depracted aliases. (Replaced by `array-copy-in-order!' and
125 `array-map-in-order'.)
127 2000-06-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
129 * gc.h (SCM_VALIDATE_CELL): Rewritten.
130 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
131 SCM_SET_CELL_OBJECT): Use new version of SCM_VALIDATE_CELL.
132 (Thanks to Han-Wen Nienhuys.)
134 2000-06-10 Michael Livshin <mlivshin@bigfoot.com>
136 * guile-doc-snarf.in: don't pipe the CPP output right into sed --
137 write it to the temp file first and check the CPP return code.
138 (I introduced this bug earlier, and this probably caused people
139 with non-GNU C preprocessors to get empty *.x files and not to
140 have the build fail right away...).
142 * scmsigs.c (s_scm_sigaction): guard the SIGSYS case with an ifdef
143 -- at least my libc5-based Linux system doesn't define SIGSYS.
145 2000-06-08 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
147 * snarf.h, guile-snarf.awk.in, guile-snarf.in: Replaced snarf
148 markers with identifiers (SCM__I, SCM__D, SCM__S, SCM__E).
149 (Thanks to Bernard Urban.)
151 2000-06-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
153 * modules.c (scm_system_module_env_p): Fixed detection of system
156 2000-06-06 Marius Vollmer <mvo@zagadka.ping.de>
158 * scmsigs.c (scm_sigaction): Silently ignore setting handlers for
159 `program error signals' because they can't currently be handled by
162 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
164 * procs.h (SCM_SET_SUBRF): Added.
166 * procs.c (scm_make_subr_opt): Don't assign to SCM_SUBRF, use
167 SCM_SET_SUBRF instead. Thanks to Bernard Urban for the bug
170 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
172 * gc.h (SCM_CARLOC, SCM_CDRLOC): Don't take the address of a SCM
175 * sort.c (scm_sorted_p, scm_merge, scm_merge_list_x,
176 scm_merge_list_step): Don't take the address of SCM_CAR. Use
177 SCM_CARLOC instead. Thanks to Bernard Urban for the bug report.
179 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
181 * boolean.h (SCM_TRUE_P): Removed, as people might use it as a
182 replacement for !SCM_FALSEP.
184 * backtrace.c (display_error_body), boolean.h (SCM_BOOLP), gc.c
185 (scm_unhash_name), gh_data.c (gh_module_lookup), load.c
186 (scm_primitive_load), print.c (scm_simple_format), procs.c
187 (scm_procedure_documentation), procs.h (SCM_TOP_LEVEL), ramap.c
188 (scm_array_fill_int), scmsigs.c (scm_sigaction), stacks.c
189 (narrow_stack, scm_make_stack, scm_stack_id), symbols.c
190 (scm_string_to_obarray_symbol), throw.c (scm_catch,
191 scm_lazy_catch, scm_ithrow), unif.c (scm_make_uve, scm_array_p,
192 scm_array_set_x, scm_bit_set_star_x, scm_bit_count_star),
193 validate.h (SCM_VALIDATE_BOOL_COPY, SCM_VALIDATE_PROC): Replace
194 uses of SCM_TRUE_P (x) with SCM_EQ_P (x, SCM_BOOL_T).
196 2000-06-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
198 * eval.c (scm_badformalsp): New static function.
199 (SCM_CEVAL): Check arguments for procedure-with-setter closures.
200 (Thanks to Keisuke Nishida.)
202 The major reason for Guile's slow loading speed has been the fact
203 that a chain of Scheme level procedures has been evaluated for
204 every top-level symbol lookup during the first pass through the
207 The following is a kludge which I suggested four years ago, and
208 which I've repeatedly suggested since. Personally, I've never
209 been bothered by Guile's slow loading speed, so I thought I would
210 let someone else do it...
212 But since the new environments will be included first in
213 Guile-1.5, I thought it would make people happy to get the kludge
216 * modules.c: Added #include "libguile/vectors.h";
217 Added #include "libguile/hashtab.h";
218 Added #include "libguile/struct.h";
219 Added #include "libguile/variable.h";
220 Capture Scheme level `module-make-local-var!' to be used in the
221 standard eval closure.
222 (scm_standard_eval_closure): New primitive.
224 * modules.h (scm_standard_eval_closure): Declare.
226 * eval.c (scm_lookupcar): Test for !SCM_CONSP (SCM_CAR (env))
227 instead of SCM_TRUE (scm_procedurep (SCM_CAR (env))).
229 * symbols.c (scm_sym2vcell): Bypass dispatch in the evaluator for
230 standard eval closures.
232 * variable.c: Code layout fixes.
234 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
236 * Makefile.am: Added LIBS line to libpath which accidentally
237 disappeared in the change of 2000-06-01.
238 (Thanks to Dale P. Smith.)
240 2000-06-03 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
242 * scmsigs.c (scm_segfault): Removed. (Was probably added by
243 mistake since it is not mentioned in ChangeLog.)
245 * gc.h (SCM_VALIDATE_CELL): Cast result to (void) in order to
246 avoid compiler warnings in gcc. (Does this work for other
249 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
251 * gc.h (SCM_VALIDATE_CELL): Don't "use" the value returned by
253 (SCM_CARLOC, SCM_CDRLOC): Define directly instead of using
254 SCM_CELL_OBJECT_0 and SCM_CELL_OBJECT_1. It's not correct to take
255 the address of these expressions since they use SCM_VALIDATE_CELL.
256 (Thanks to Bernard Urban.)
258 * dynl.c: Changed #include <ltdl.h> --> #include
259 "libltdl/ltdl.h". (Thanks to Bill Schottstaedt.)
261 2000-06-01 Craig Brozefsky <craig@red-bean.com>
263 * Makefile.am: libguile_la_LDFLAGS gets -version-info args
264 from GUILE-VERSION definition of LIBGUILE version. Added to
265 libpath.h definitions for guileversion and libguileversion which
266 both get their values from GUILE-VERSION definition.
268 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
270 * numbers.h (SCM_BIGP): Don't use SCM_SMOB_PREDICATE in header
271 file: Code using numbers should not be required to include
274 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
276 * coop-threads.c.cygnus, coop-threads.h.cygnus, fsu-pthreads.h,
277 mit-pthreads.c, mit-pthreads.h: Deleted.
279 * Makefile.am (EXTRA_DIST), scmsigs.c, threads.[ch]: Drop
280 references to deleted files and fsu/mit thread support in
283 2000-05-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
285 * hooks.c (symbol_name, scm_create_hook): Restored the original
286 behaviour of scm_create_hook. Changing it was bad as Carl
287 R. Witty has pointed out.
289 * gc.c (scm_init_gc): We can still rely on scm_create_hook to
292 2000-05-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
294 * gc.c (scm_init_gc): Protect scm_after_gc_hook, since this will
295 soon not be done by scm_create_hook any longer.
297 * hooks.c (make_hook, print_hook, scm_create_hook,
298 scm_make_hook_with_name, scm_make_hook), hooks.h (SCM_HOOK_NAME,
299 SCM_HOOK_PROCEDURES, SCM_SET_HOOK_PROCEDURES,
300 scm_make_hook_with_name), init.c (scm_boot_guile_1): Hooks no
301 longer have names. As an intermediate solution, the name
302 predicate is emulated via object properties, but use of this
303 feature is deprecated.
305 * hooks.h (scm_free_hook): Removed, as it is never defined.
307 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
309 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_FIXABLE):
310 Un-deprecated since otherwise user code can't determine whether a
311 number fits into an inum any longer. The names should be changed
314 * numbers.c (scm_big2inum): Eliminated use of SCM_UNEGFIXABLE.
316 * tags.h (SCM_UNPACK_CAR): Deprecated.
318 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
320 * filesys.h (SCM_OPDIRP), fluids.h (SCM_FLUIDP, SCM_FLUID_NUM),
321 fports.h (SCM_OPFPORTP, SCM_OPINFPORTP, SCM_OPOUTFPORTP), hooks.h
322 (SCM_HOOK_ARITY), keywords.h (SCM_KEYWORDP, SCM_KEYWORDSYM),
323 numbers.h (SCM_NUMP, SCM_BIGSIGN, SCM_BDIGITS, SCM_NUMDIGS):
324 Replace SCM_UNPACK_CAR appropriately. Don't access cells via
325 SCM_{SET}?C[AD]R unless they are known to be cons cells.
327 * gc.c (scm_heap_seg_data_t, scm_mark_locations, scm_cellp,
328 init_heap_seg): Remove unused struct member variable 'valid'.
330 2000-05-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
332 * fports.c (fport_write), ports.c (scm_markstream, scm_port_mode,
333 scm_print_port_mode), ports.h (SCM_OPPORTP, SCM_OPINPORTP,
334 SCM_OPOUTPORTP, SCM_INPUT_PORT_P, SCM_OUTPUT_PORT_P, SCM_OPENP),
335 procs.h (SCM_CLOSCAR), unif.h (SCM_ARRAY_NDIM, SCM_ARRAY_CONTP),
336 variable.h (SCM_VARIABLEP): Replace SCM_UNPACK_CAR
339 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
341 * gc.c (free_list_length), hash.c (scm_hasher), macros.c
342 (scm_macro_type), objects.c (scm_class_of), options.c
343 (scm_options), print.c (scm_iprin1), strports.c (st_seek), throw.c
344 (SCM_LAZY_CATCH_P): Replace SCM_UNPACK_CAR appropriately.
346 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
348 * eval.c (scm_macroexp, SCM_CEVAL, scm_force), tags.h: Replace
349 SCM_UNPACK_CAR with SCM_CELL_TYPE or SCM_CELL_WORD_0.
351 * eval.c (scm_force): Add documentation.
353 * eval.c (scm_force, scm_cons_source): Don't access cells via
354 SCM_{SET}?C[AD]R unless they are known to be cons cells.
356 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
358 * strings.h (SCM_NSTRINGP, SCM_NRWSTRINGP), tags.h
359 (SCM_NDOUBLE_CELLP), vectors.h (SCM_NVECTORP): Deprecated.
361 * gc.c (scm_igc), gc.h (SCM_PTR_MASK, SCM_PTR_LT): Removed #ifdef
362 nosve #endif conditionally compiled code.
364 2000-05-23 Michael Livshin <mlivshin@bigfoot.com>
366 * gc.c (scm_heap_seg_data_t): fixed comment for the `span' member.
368 2000-05-22 Michael Livshin <mlivshin@bigfoot.com>
370 * guile-doc-snarf.in: put the preprocessed file through sed to
371 trim all lines to 1024 chars. I hope it doesn't break anybody's
372 sed. we'll see. (note: this is lossy trimming, i.e. the spill
373 isn't wrapped around but actually chopped off. this seemed to me
374 safe because the current snarfer doesn't understand multi-line
375 cookies anyway. in the long term, it would be nice not to depend
376 on AWK for anything.)
378 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): reverted
379 the previous change to this macros, after deciding to torture the
382 2000-05-21 Michael Livshin <mlivshin@bigfoot.com>
384 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): brought
385 the yucky, ugly and nasty conditional compilation back. sorry,
386 but it was either that or requiring GAWK to build Guile.
387 (lots of places): removed the code that implemented the old GC
390 * init.c (scm_boot_guile_1): removed the code conditioned on
391 !GUILE_NEW_GC_SCHEME.
393 * __scm.h: (GUILE_NEW_GC_SCHEME): removed.
395 * gc.c (scm_protect_object, scm_unprotect_object): change the
396 implementation to more efficient (at least in the time complexity
397 sense). the calls should now also be thread-safe -- I suspect
398 that people expect them to be. (thanks to Han-Wen Nienhuys)
399 (lots of places): removed the code that implemented the old GC
402 * hashtab.c (scm_hash_fn_create_handle_x): add missing
403 SCM_REALLOW_INTS before return. I really wonder about the
404 possible interactions between hashtables, threads & GC. it
405 doesn't look healthy at all.
407 2000-05-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
409 * unif.c (scm_bit_count): Fixed the parameter checks. Thanks to
412 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
414 * __scm.h (SCM_DEBUG_CELL_ACCESSES), gc.h (SCM_): Added as a new
415 debug option to verify all accesses to cells actually access
418 * gc.h (SCM_VALIDATE_CELL): Added. Only performs validation if
419 SCM_DEBUG_CELL_ACCESSES is set to 1.
421 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
422 SCM_SET_CELL_OBJECT): Use SCM_VALIDATE_CELL to check every cell
425 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
427 * gh_data.c (gh_scm2chars, gh_scm2shorts, gh_scm2longs,
428 gh_scm2floats, gh_scm2doubles): Change !SCM_NIMP to SCM_IMP.
430 * gc.c (scm_cellp): Fixed and simplified.
432 * throw.c (JBJMPBUF, SETJBJMPBUF, SCM_JBDFRAME, SCM_SETJBDFRAME,
433 make_jmpbuf, scm_init_throw): Now using double cells to represent
434 jump buffers when using debug extensions.
438 2000-05-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
440 * gh.h gh_data.c gh_funcs.c (gh_new_procedure*, gh_chars2byvect,
441 gh_shorts2svect, gh_longs2ivect, gh_ulongs2uvect, gh_floats2fvect,
442 gh_doubles2dvect, gh_doubles2scm, gh_define, gh_lookup,
443 gh_module_lookup): Accept const pointers as parameters.
445 * gh.h gh_data.c (gh_int2scmb): Deprecated.
447 2000-05-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
449 * __scm.h (SCM_DEBUG_REST_ARGUMENT): Renamed from
450 SCM_DEBUG_REST_ARGUMENTS in order to clarify that we don't test
451 the actual arguments in the list, but rather the rest argument as
454 * validate.h (SCM_VALIDATE_REST_ARGUMENT): Added.
456 * async.c (scm_noop), eval.c (scm_map, scm_for_each), list.c
457 (scm_list_star, scm_append, scm_append_x), ports.c
458 (scm_close_all_ports_except), ramap.c (scm_array_map_x,
459 scm_array_for_each), regex-posix.c (scm_make_regexp), stacks.c
460 (scm_make_stack), strings.c (scm_string_append), struct.c
461 (scm_make_struct, scm_make_vtable_vtable): Validate rest arguments.
463 * dynl.c (DYNL_GLOBAL, sysdep_dynl_link, kw_global, sym_global,
464 scm_dynamic_link, scm_init_dynamic_linking), dynl.h
465 (scm_dynamic_link): Removed possibility to pass flags to
466 scm_dynamic_link, as it had no effect anyway.
468 * filesys.c (scm_fcntl): Made single optional rest argument into
469 a standard optional argument.
471 * hooks.c (scm_run_hook): A list of rest arguments is never
474 * list.c (scm_append, scm_append_x), stacks.c (scm_make_stack),
475 strings.c (scm_string_append): Don't perform half-hearted checks
476 to see whether the rest argument forms a proper list any more, use
477 SCM_VALIDATE_REST_ARGUMENTS instead.
479 * ports.c (scm_close_all_ports_except): Accept empty list of rest
482 * posix.c (scm_convert_exec_args), print.c (scm_simple_format):
483 Simplify verification of rest argument.
485 * stacks.c (scm_make_stack), stacks.h (scm_make_stack), throw.c
486 (ss_handler, handler_message): Make first mandatory rest argument
487 of scm_make_stack into a standard mandatory argument.
489 * unif.c (scm_transpose_array, scm_enclose_array,
490 scm_array_in_bounds_p), unif.h (scm_transpose_array,
491 scm_enclose_array, scm_array_in_bounds_p): Make first mandatory
492 rest argument into a standard mandatory argument.
494 2000-05-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
496 * __scm.h: Added SCM_DEBUG as default debug option. (Thanks to
497 Keisuke Nishida for the suggestion.) Added debug option
498 SCM_DEBUG_REST_ARGUMENTS.
500 * eval.c (scm_map, scm_for_each): Make sure all lists have the
501 same length. Also, removed redundant parameter checks.
503 2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
505 * Makefile.am: Let 'make clean' remove *.x and *.doc files.
507 * __scm.h: Improved explanation of giving options to make.
509 * __scm.h (SCM_DEBUG_TYPING_STRICTNESS), tags.h
510 (SCM_STRICT_TYPING, SCM_DEBUG_TYPING_STRICTNESS): Renamed
511 SCM_STRICT_TYPING to SCM_DEBUG_TYPING_STRICTNESS and moved the
512 corresponding declaration and comment to __scm.h.
514 * _scm.h (errno), gc.h (SCM_CELLPTR, SCM_PTR_LT), numbers.c
515 (scm_remainder, scm_modulo), numbers.h (SCM_SRS, SCM_MAKINUM,
516 SCM_INUM): Removed conditionally compiled code for Turbo C.
518 * gdbint.c (gdb_maybe_valid_type_p): Eliminated call to scm_tag.
519 That check can be assumed to be redundant except for very rare
520 conditions that actually indicate broken heap data.
522 2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
524 * numbers.c (scm_logcount, scm_integer_length): Reordered
527 2000-05-15 Gary Houston <ghouston@arglist.com>
529 * stime.c (scm_strftime): don't reset TZ if zone is an empty
530 string. append a "0" to the zone for TZ.

552 * fports.c (scm_fport_buffer_add), ports.c (scm_input_port_p,
553 scm_output_port_p), print.c (scm_get_print_state), validate.h
554 (SCM_VALIDATE_CHAR): Replace use of deprecated macros
555 SCM_INPORTP, SCM_OUTPORTP, SCM_ICHRP by SCM_INPUT_PORT_P,
556 SCM_OUTPUT_PORT_P, SCM_CHARP, respectively.
558 2000-05-14 Gary Houston <ghouston@arglist.com>
560 * stime.c (scm_strftime): if HAVE_TM_ZONE is not defined, hack the
561 TZ environment variable so that the %Z format returns the zone
562 from the input vector instead of the system default.
564 from Keisuke Nishida:
565 * fports.c (scm_setvbuf): minor docstring fix.
566 * ports.h (scm_generic_fgets): obsolete prototype deleted.
568 2000-05-11 Dirk Herrmann <D.Herrmann@tu-bs.de>

577 as part of the interface and are marked as deprecated in the
580 * numbers.c (scm_make_real, scm_make_complex): Inlined the
581 corresponding macros SCM_NEWREAL and SCM_NEWCOMPLEX,
584 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX, SCM_INEXP, SCM_CPLXP,
585 SCM_REAL, SCM_IMAG, SCM_REALPART, scm_makdbl, SCM_SINGP,
586 SCM_NO_BIGDIG, SCM_NUM2DBL, scm_dblproc): Deprecated.

591 SCM_SET_CELL_WORD, SCM_SET_CELL_OBJECT): Scheme cells now consist
592 of two scm_bits_t values instead of two SCM values, because it is
593 legal for cell entries to hold values that are not scheme objects.
595 (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR):
596 Use SCM_SETC[AD]R to modify contents of pairs.

600 * numbers.c (IS_INF, isfinite): Added FIXME comment.
602 (scm_abs, scm_magnitude): Make these two independent of each
603 other. scm_abs now reports an error if given a complex argument.
605 (scm_istr2flo, scm_integer_p). Use SCM_REAL_VALUE instead of
606 SCM_REALPART if the object is known to be real.
608 (scm_init_numbers): No need to use SCM_NEWREAL macro for speed
611 * numbers.h (SCM_SINGP): Set to 0 instead of SCM_BOOL_F.
613 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>

621 vector_sum_squares), unif.c (scm_make_uve, scm_array_p,
622 scm_array_set_x): Use SCM_REAL_VALUE instead of SCM_REALPART if

624 deprecated SCM_CPLXP. Use SCM_INEXACTP instead of deprecated
627 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
629 * numbers.c: No need to include unif.h.
631 (IS_INF): Returned to old test for now: x == x + 1 will not work
632 for large numbers due to rounding errors.
633 Thanks to Kalle Olavi Niemitalo.
635 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
637 * numbers.c (scm_divbigdig): Removed outdated comment.

646 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
648 * numbers.c (IS_INF): The new test is x == x + 1. The old test
649 x == x/2 did not work for zero values. Thanks to Han-Wen Nienhuys
652 (scm_number_to_string, scm_sum, scm_difference, scm_two_doubles,
653 scm_num2long, scm_num2long_long, scm_num2ulong): Reordered
656 2000-05-09 Marius Vollmer <mvo@zagadka.ping.de>
658 * scmsigs.c (take_signal): Execute SCM_ASYNC_TICK for SIGSEGV,
659 SIGILL and SIGBUS signals. These signals are not continuable and
660 must be handled for real right away.
662 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
664 * numbers.c (scm_zero_p, scm_positive_p, scm_negative_p,

670 * feature.c: No need to include "libguile/smob.h"
672 (scm_loc_features, features, scm_add_feature, scm_init_feature):
673 Removed variable 'scm_loc_features' as a pointer to the SCM value
674 holding the features list. Using variable 'features' instead,
675 which holds the interned pair. Thus, SCM_SETCDR can be used
676 instead of pointer trickery.
678 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
680 * alist.c (scm_acons): Use SCM{_SET}?_CELL_OBJECT as long as a
681 cell is not known to be a valid pair.
683 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
685 * eval.c (ASRTSYNTAX, scm_m_body, scm_m_letrec1): Removed
686 ASRTSYNTAX. Using SCM_ASSYNT instead.

700 long as a cell is not known to be a valid pair.
702 (scm_pair_p): Eliminated redundant SCM_IMP test.
704 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
706 * eval.c (scm_m_body, scm_macroexp, unmemocopy, scm_eval_args,

716 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest):
717 Fixed some goto-related initialization bugs (introduced by me).
719 2000-05-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
721 * numbers.h (SCM_INUM0): Uses SCM_MAKINUM instead of SCM_PACK.
723 * dynl.c (dynl_obj, DYNL_OBJ, get_dynl_obj): Removed.
725 (DYNL_FILENAME, DYNL_HANDLE): Use SCM_CELL... macros instead of
728 (SET_DYNL_HANDLE): Added.

733 better error message when accessing unlinked dynamic objects.
734 Eliminated call to get_dynl_obj.
736 2000-05-03 Marius Vollmer <mvo@zagadka.ping.de>
738 * scmsigs.c (orig_handlers) [!HAVE_SIGACTION]: Fix declaration to
739 be an array of function pointers instead of being a pointer to an
740 array returning function. Thanks to Kalle Olavi Niemitalo!
742 2000-05-03 Dirk Herrmann <D.Herrmann@tu-bs.de>
744 * numbers.c (scm_divbigbig, scm_divbigint), numbers.h
745 (scm_divbigbig, scm_divbigint): Don't return zero any more to
746 indicate that a division has a remainder, return SCM_UNDEFINED
747 instead. It is improbable that anyone actually used these
748 functions outside of numbers.c. For this reason and due to the
749 change in behaviour the functions are static now. Thus, if
750 surprisingly there are users of these functions they will at least
753 * numbers.c: Removed #ifdef SCM_BIGDIG #endif in those functions,
754 that already have a clean dispatch order. Note: SCM_BIGDIG is
757 * numbers.c (scm_inexact_p): Simplified.
759 * numbers.c (scm_num_eq_p, scm_less_p, scm_max, scm_min,
760 scm_product, scm_num2dbl, scm_angle): Reordered dispatch
761 sequence, thereby fixing some comparisons of SCM values with
764 * numbers.c (scm_divide): Division by zero of inums leads to an
765 error now. (Formerly, an infinite number was returned.)
767 Respect the fact, that scm_divbigbig does now return SCM_UNDEFINED
768 if a division has a remainder.
770 2000-05-02 Gary Houston <ghouston@arglist.com>
772 * Makefile.am (INCLUDES): add ${INCLTDL} (thanks to Tim Mooney).

803 libguile.h: moved to top level directory.
805 2000-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
807 * numbers.c (SCM_SWAP): Moved to the top of the file to allow for
810 * numbers.c (scm_modulo, scm_gcd, scm_lcm, scm_logand, scm_logior,
811 scm_logxor): Reordered dispatch sequence, thereby fixing some
812 comparisons of SCM values with integer constants.

840 * pairs.c (cxrs, scm_init_pairs): Simplify initialization of
843 * procs.c (scm_init_iprocs), procs.h (scm_subr, scm_iproc,
844 scm_dsubr, scm_init_iprocs): Removed.
846 * procs.h (SCM_SUBRF, SCM_DSUBRF): Access the cell words
847 directly instead of casting a cell to a C struct.

909 the root build directory.
911 * numbers.c (scm_odd_p, scm_even_p): Use SCM_WRONG_TYPE_ARG
912 instead of SCM_ASSERT (0, ...). (Some compilers will complain
913 about control reaching end of function otherwise, and, besides,
914 the new code is not less clear.)

935 functions respectively signal wrong type arguments. Hopefully
936 this will allow for easier separation when goops is integrated.
938 2000-04-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
940 * gc.c (which_seg): Use SCM2PTR to convert a non immediate SCM
941 variable into a pointer to a heap cell.

988 * unif.c (l2ra): Don't eliminate the call to scm_array_set_x

1015 a field of scm_bits_t values.
1017 * unif.c (l2ra): Don't test result of scm_array_set_x against

1043 scm_struct_free_light, scm_struct_free_standard,
1044 scm_struct_free_entity): Struct data regions (and thus also
1045 vtable data regions) are now C arrays of scm_bits_t elements.
1047 * gc.c (scm_gc_mark, scm_gc_sweep, scm_unhash_name): Made the
1048 mixup of glocs and structs explicit.

1219 * async.h: kill the scm_async_t struct. having a heap cell
1220 pretending to be a C struct is not helthy, and is not needed here

1290 * guardians.c (scm_guardian_zombify): mark all zombies in a
1291 separate loop after processing all the currently known live
1292 guardians, so as to not introduce order dependencies (thanks to
1293 Gary Houston). note that the order problems are still there if
1294 some guardians are themselves zombies, but that's a sick case that
1295 I'm not going to worry about.
1296 also, make another outer loop to process zombified
1297 guardians (which are uncovered while marking zombies).

1535 * boolean.h (SCM_TRUE_P): New macro.
1537 * boolean.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOLP), pairs.h
1538 (SCM_NULLP, SCM_NNULLP): Use SCM_EQ_P to compare SCM values.
1540 2000-03-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1542 * continuations.h (SCM_CONTREGS, SCM_SET_CONTREGS): New macros to
1543 access continuation data.
1545 (SCM_SETJMPBUF): Deprecated. Use SCM_SET_CONTREGS instead.
1547 (SCM_JMPBUF, SCM_DYNENV, SCM_THROW_VALUE, SCM_BASE, SCM_SEQ,
1548 SCM_DFRAME): Use SCM_CONTREGS instead of SCM_CHARS to access
1551 * continuations.c (scm_make_cont), init.c (start_stack),
1552 root.c (scm_internal_cwdr): Use SCM_SET_CONTREGS instead of
1555 2000-03-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1557 * symbols.h (SCM_LENGTH, SCM_SETLENGTH): Access the length field
1558 of strings and symbols by using SCM_{SET_}?CELL_WORD_0.
1560 (SCM_CHARS, SCM_UCHARS, SCM_SETCHARS): Use SCM_{SET_}?CELL_WORD_1
1561 to access the char * field of strings and symbols.
1563 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
1565 * gc.h (SCM_NEWCELL, SCM_NEWCELL2): Use SCM_SET_CELL_TYPE to set
1566 the type entry of a new cell. Added a comment about things to
1567 remember when updating the list of free cells.
1569 (SCM_FREEP, SCM_MARKEDP): Use SCM_CELL_TYPE to access the type
1572 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
1574 * pairs.h (SCM_CAR, SCM_CDR, SCM_SETCAR, SCM_SETCDR): Use
1575 SCM_CELL_OBJECT and SCM_SET_CELL_OBJECT. This change implies that
1576 with strict type checking enabled these macros will only work if
1577 given valid SCM parameters.
1579 (SCM_GCCDR): Moved to tags.h.
1581 * tags.h (SCM_GCCDR): Moved here from pairs.h.
1583 2000-03-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
1585 * tags.h (SCM2PTR, PTR2SCM): Moved to gc.h.
1587 * pairs.h (scm_cell, SCM_CELLPTR, SCM_CELL_WORD*, SCM_CELL_OBJECT*,
1588 SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*, SCM_CELL_TYPE,
1589 SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK, SCM_PTR_GT,
1590 SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC, SCM_NEWCELL,
1591 SCM_NEWCELL2): Moved to gc.h.
1593 (SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR, SCM_SETAND_CDR,
1594 SCM_SETOR_CAR, SCM_SETOR_CDR): Moved to gc.h. These names should
1595 be changed, though, since the macros are not only pair related.
1599 * gc.h (SCM2PTR, PTR2SCM, scm_cell, SCM_CELLPTR, SCM_CELL_WORD*,
1600 SCM_CELL_OBJECT*, SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*,
1601 SCM_CELL_TYPE, SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK,
1602 SCM_PTR_GT, SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC,
1603 SCM_NEWCELL, SCM_NEWCELL2, SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR,
1604 SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR): Moved here from
1607 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
1609 * tags.h (SCM_STRICT_TYPING): New macro that, if defined,
1610 activates strict compile time type checking for variables of
1612 (SCM, SCM_PACK, SCM_UNPACK): Define according to whether
1613 SCM_STRICT_TYPING or SCM_VOIDP_TEST are defined.
1614 (SCM_EQ_P): Defined as a macro equivalent for eq?.
1616 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
1618 * tags.h (SCM_POINTERS_MUNGED): Removed.
1620 * gc.c (scm_gc_sweep, init_heap_seg): Removed use of
1621 SCM_POINTERS_MUNGED, thus fixing some illegal casts to SCM.
1623 2000-03-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
1625 * pairs.h (SCM_CELL_OBJECT, SCM_CELL_OBJECT_[0-3],
1626 SCM_SET_CELL_OBJECT, SCM_SET_CELL_OBJECT_[0-3], SCM_CELL_TYPE,
1627 SCM_SET_CELL_TYPE): Added a set of low level macros for accessing
1629 (SCM_CELL_WORD_[0-3]): Renamed from the SCM_CELL_WORD[0-3].
1631 * procs.h, procs.c: Instead of SCM_{SET_}?CELL_WORD[12], use the
1632 newly introduced SCM_{SET_}?CELL_OBJECT_[12] macros.
1634 2000-03-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1636 * tags.h: Disabled definition of SCM_VOIDP_TEST.
1638 Defining SCM as void * introduces problems which haven't been
1639 handled yet. Developers who work with these issues can enable it
1640 in their working copies.
1642 Disabling this definition exposes a set of newly introduced and
1643 older misuses of types which causes warning messages during
1644 compilation. We'll fix this successively.
1646 * gc.c (scm_mark_locations): Changed * (SCM **) X --> * (SCM *) X
1647 in order to obtain a value of type SCM.
1648 (scm_cellp): Updated with new changes to scm_mark_locations.
1650 * continuations.h (SCM_SETJMPBUF): Cast second arg into SCM.
1652 * continuations.c (scm_make_cont): Removed cast of size_t into
1655 * symbols.h (SCM_SETCHARS): Cast second arg into SCM.
1657 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
1659 * numbers.h (SCM_SETNUMDIGS): Use SCM_BIGSIZEFIELD macro for
1660 shifting, not constant. Thanks to Dale P. Smith.
1662 * numbers.c (scm_sum, scm_difference): Don't test a SCM value
1663 for being less than zero. Decode it to a C value first. Again,
1666 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
1668 * numbers.h, ramap.c, struct.h, vectors.h: Don't use SCM2PTR for
1669 non scheme values. If raw data is stored in SCM variables, it has
1670 to be accessed using SCM_UNPACK until a better solution is found.
1672 2000-03-22 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1674 * tags.h (SCM_ECONSP, SCM_NECONSP): More corrections of
1675 pointer-arithmetic induced by the SCM_PACK/UNPACK change.
1677 * print.c (scm_iprin1): SCM_PACK/UNPACK corrections.
1679 * gc.c (scm_gc_sweep): SCM_PACK/UNPACK corrections.
1681 * eval.c (SCM_CEVAL, scm_unmemocar): SCM_PACK/UNPACK corrections.
1683 * dynwind.c (scm_swap_bindings): SCM_PACK/UNPACK corrections.
1685 * async.c, __scm.h: Removed lots of the old async click logic. It
1686 is possible to reinsert it by defining GUILE_OLD_ASYNC_CLICK in
1687 __scm.h. Let's try this out and dump the old code after the
1688 threads reorganization.
1689 (set-tick-rate, set-switch-rate): Conditionally removed.
1691 2000-03-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1693 * gc.c (scm_gc_mark): Bugfix 1: The recent SCM_PACK/UNPACK change
1694 made SCM values into pointers. This turned an arithmetic
1695 computation of the address of the vcell into a pointer-arithmetic
1696 one, thereby screwing up marking of structs.
1697 Bugfix 2: Removed incompletely introduced loop variable `j' used
1698 when protecting the tail array of a struct.
1700 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
1702 * struct.h (SCM_STRUCT_DATA): Don't cast SCM values to pointers.
1704 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
1706 * symbols.h, symbols.c (scm_strhash): Declare the string
1707 parameter as constant, since it is not modified.
1709 * symbols.c (scm_intern_obarray_soft,
1710 scm_sysintern0_no_module_lookup): Can now pass constant strings
1711 to scm_strhash without need for casting.
1713 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
1715 * vectors.h (SCM_VELTS, SCM_VELTS_AS_STACKITEMS): Don't cast SCM
1716 values to pointers. Use SCM2PTR instead.
1718 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
1720 * async.c (scm_set_tick_rate, scm_set_switch_rate): Don't unpack
1721 results of SCM_INUM.
1723 2000-03-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1725 * init.c (scm_boot_guile_1): Renamed GUILE_GC_TRIGGER_1 -->
1726 GUILE_MIN_YIELD_1, GUILE_GC_TRIGGER_2 --> GUILE_MIN_YIELD_2.
1727 GUILE_MIN_YIELD_X now take *positive* fractions of heap size.
1729 * gc.c, gc.h (SCM_MIN_YIELD_1, SCM_MIN_YIELD_2,
1730 min_yield_fraction, min_yield, adjust_min_yield): Renamed from
1731 SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2, gc_trigger_fraction,
1732 gc_trigger, adjust_gc_trigger.
1734 * gc.c (alloc_some_heap): Further improvement of minimal heap size
1736 (SCM_MAX): New macro.
1737 (scm_freelist_t): New field: collected_1. Previous amount of
1739 (gc_sweep_freelist_finish): Trigger based on two last values of
1740 freelist->collected to avoid unnecessary allocation due to
1742 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2):
1743 Adjusted to 45000 cells, 40% and 40%. Gives quick startup
1744 without extra heap allocation.
1746 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
1748 * numbers.h (SCM_MAKINUM): The parameter to SCM_MAKINUM should
1749 already be a C value. No need to unpack it.
1751 * numbers.c (scm_long_long2num): Cast the parameter to scm_bits_t
1752 if we know it fits into an inum.
1754 * ramap.c (ramap_rp): An scm_tc7_[ui]vect object does point to a
1755 field of long values. In contrast, SCM_VELTS accesses a field of
1758 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1760 * gc.c (scm_gc_stats): Inserted explanation of local_scm_mtrigger
1762 (scm_gc_yield_1): New variable: Holds previous yield. Used to
1763 make better judgements.
1764 (gc_sweep_freelist_finish): Inserted explanation of use of
1767 * print.h, stacks.h, options.c, options.h: Changed C++
1770 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
1772 * tags.h (SCM2PTR, PTR2SCM): Use SCM_PACK / SCM_UNPACK correctly.
1774 * numbers.h (SCM_INUMP, SCM_MAKINUM, SCM_INUM0, SCM_COMPLEX_REAL,
1775 SCM_COMPLEX_IMAG, SCM_NUMP, SCM_BDIGITS): Use SCM_PACK /
1776 SCM_UNPACK / SCM2PTR correctly.
1778 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1780 * gc.c (adjust_gc_trigger): Improved documentation.
1781 (alloc_some_heap): Since gc_trigger is used against
1782 freelist->collected, this is the value which should be used to
1783 predict minimum growth.
1785 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
1787 * eval.h: Fix mixup of packed/unpacked SCM values. (Thanks
1788 Thien-Thi Nguyen for the patch.)
1790 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
1792 * numbers.c (scm_ash): Fixed typing problems with the second
1793 parameter and added some documentation. (Thanks Thien-Thi Nguyen
1794 for indicating the problem.)
1796 2000-03-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1798 * gc.c, gc.h (scm_gc_yield): New variable.
1799 (adjust_gc_trigger): Use scm_gc_yield.
1800 (alloc_some_heap): Use scm_gc_yield instead of
1801 scm_gc_cells_collected.
1803 * coop-threads.c: Addd #include "root.h", #include "strings.h".
1805 * debug.c: Added #include "root.h". (Thanks to Thien-Thi Nguyen.)
1807 * gc.c (scm_gc_for_newcell, adjust_gc_trigger): Improved GC
1808 trigger adjustmeant: Take yield (freed cells) for all freelists
1810 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Tuned
1811 to 50000 cell heap with 45% trigger.
1812 (scm_gc_cells_collected): Reintroduced.
1813 (SCM_HEAP_SIZE): New macro.
1814 (scm_gc_sweep): Reintroduced correct computation of
1815 scm_cells_allocated.
1816 (scm_freelist_t): Corrected commentary for field `cluster_size':
1817 Clustersize counts objects, not cells; New member
1818 `clusters_allocated'.
1820 2000-03-19 Michael Livshin <mlivshin@bigfoot.com>
1822 * *.[hc]: add Emacs magic at the end of file, to ensure GNU
1825 2000-03-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1827 * threads.h: Added #include "libguile/throw.h". (Thanks to
1830 2000-03-18 Michael Livshin <mlivshin@bigfoot.com>
1832 * tags.h: (SCM_DOUBLE_CELLP, SCM_NDOUBLE_CELLP): new macros (bad
1833 names, anyone got any better ones?)
1835 * gc.h: (typedef struct scm_freelist_t) remove from here.
1837 * gc.c: (CELL_UP, CELL_DN) made these macros take additional
1838 parameter (the span).
1839 (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK) new macros.
1840 (typedef struct scm_freelist_t) moved here from gc.h, it had no
1841 business being externally visible.
1842 (typedef struct scm_heap_seg_data_t) renamed from
1843 scm_heap_seg_data, to be style-compliant.
1844 (scm_mark_locations) if the possible pointer points to a
1845 double-cell, check that it's properly aligned.
1846 (init_heap_seg) align double-cells properly, work with the
1847 assumption that the segment size divides cleanly by cluster size.
1848 (round_to_cluster_size) new function.
1849 (alloc_some_heap, make_initial_segment) use round_to_cluster_size
1850 to satisfy the new init_heap_seg invariant.
1852 2000-03-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
1854 * _scm.h: Don't include async.h everywhere...

1909 2000-03-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1911 * gc.c, gc.h: Cleanup of the change of 2000-03-15.
1912 Cluster sizes are now independent of GC trigger values.
1913 GUILE_GC_TRIGGER_n can now specify a relative trigger value:
1914 A negative integer gives fraction of total heap size in percent.
1915 (SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Default values set to -40.
1917 * init.c (scm_boot_guile_1): Introduced new variable
1918 GUILE_MAX_SEGMENT_SIZE; New environment variable names:
1919 GUILE_INIT_SEGMENT_SIZE_1, GUILE_GC_TRIGGER_1,
1920 GUILE_INIT_SEGMENT_SIZE_2, GUILE_GC_TRIGGER_2
1922 2000-03-16 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1924 * __scm.h (GC_FREE_SEGMENTS): Disable this until we have made
1925 freeing of segment work with the new GC scheme. (Thanks to
1926 Michael Livshin.) Oops, also happened to make GUILE_NEW_GC_SCHEME
1927 the default, but I'll let this change stay in CVS Guile since this
1928 code is not expected to contain serious bugs.
1930 2000-03-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1932 * gc.c, gc.h (scm_map_free_list): Define also if GUILE_DEBUG is
1934 (scm_free_list_length): New procedure (GUILE_DEBUG).
1935 Fixed a small but serious bug introduced by the previous change.
1937 * gc.c (scm_gc_sweep): Moved variable n_objects to inner sweep
1938 loop and declare as register.
1940 * gc.c (scm_gc_sweep): Sigh... forgot to clear private freelists
1943 Wed Mar 15 08:27:04 2000 Greg J. Badros <gjb@cs.washington.edu>
1945 * fluids.c: Docstring patch from Keisuke Nishida. Some
1946 reindentation, too, and a couple formals renamed. Should
1947 fluid-set! return UNSPECIFIED instead of a value?
1949 Wed Mar 15 08:24:58 2000 Greg J. Badros <gjb@cs.washington.edu>
1951 * Makefile.am: Separate out DOT_X_FILES and DOT_DOC_FILES, and
1952 generate the latter from the concrete listing of the former. Then
1953 make guile-procedures.txt depend on DOT_DOC_FILES instead of
1954 *.doc, so that rebuilding it works.
1956 Wed Mar 15 08:12:14 2000 Greg J. Badros <gjb@cs.washington.edu>
1958 * libguile.h: Include libguile/validate.h. Thanks Keisuke Nishida!
1960 * guile-snarf.awk.in: Replace docstring line-ending \n" and \n\n"
1961 with nothing and \n, respectively. Thanks Keisuke Nishida for
1962 noticing this problem.
1964 2000-03-15 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1966 * __scm.h (GUILE_NEW_GC_SCHEME): Define this if you want to test a
1967 new way of allocating heap. It makes Guile fast, but still
1970 * gc.c, gc.h, pairs.h, init.c: Implementation of a new way of
1971 allocating heap. The basic idea is to trigger GC every Nth
1972 allocated cell and grow heap when free list runs out. The scheme
1973 has been extended so that GC isn't triggered until all remaining
1974 cells are used. The implementation is also prepared for
1975 development in the direction of POSIX threads.
1977 * gc.c (SCM_EXPHEAP): In order to grow by a factor of 1.5,
1978 SCM_EXPHEAP should return half of the heap size.
1980 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1982 The following change to init.c is only enabled if Guile was
1983 configured with --enable-guile-debug.
1985 * init.c (scm_i_getenv_int): New function.
1986 (scm_boot_guile_1): Use the environment variables
1987 GUILE_INIT_HEAP_SIZE, GUILE_INIT_HEAP_SIZE2 to select heap size if
1988 they exist. (This may be replaced by a Scheme level mechanism in
1991 * objprop.c (s_scm_set_object_property_x): Use scm_assq instead of
1992 scm_assoc. (Thanks to Keisuke Nishida.)
1994 2000-03-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1996 * eval.c, lang.c, lang.h (scm_lisp_nil, scm_lisp_t): Renamed from
1997 scm_nil, scm_t. (Thanks to Keisuke Nishida.)
1999 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2001 * init.c (scm_boot_guile_1): Use same initial segment size for
2002 1-word and 2-word segments. Having the smaller size causes Guile
2003 to GC too often. Obviously something needs to be done to allow
2004 for a smaller 2-word segment without this to happen. (The amount
2005 of heap for each type should be automatically adapted to the
2006 application somehow.)
2008 [Almost all of these changes should be documented in the NEWS
2011 * gc.h (scm_freelist_t): New type.
2013 * pairs.h (SCM_NEWCELL, SCM_NEWCELL2): Use new style freelists.
2015 * gc.c (SCM_INIT_HEAP_SIZE): Changed from 32768 --> 40000 so that
2016 all of Guile basics fits into one segment and there suitable room
2018 (SCM_EXPHEAP): Now takes an argument. Grow by a factor of 1.5
2020 (scm_freelist, scm_freelist2): Now of type scm_freelist_t.
2021 Freelists now contains information about object span, cells
2022 collected and amount of cells in heap segments belonging to the
2024 (scm_heap_size, scm_gc_cells_collected): Removed.
2026 * init.c (scm_boot_guile_1): Make 2-word segment 8K (512 cells).
2028 * Makefile.am (libguile_la_LDFLAGS): Bumped library version
2031 * __scm.h eq.c, eval.c, gc.c, gc.h, gh_data, hash.c, numbers.c,
2032 numbers.h, objects.c, ramap.c, random.c, unif.c, unif.h: Extensive
2033 rewrite of handling of real and complex numbers.
2034 (SCM_FLOATS, SCM_SINGLES): These #ifdef conditionals have been
2035 removed along with the support for floats. (Float vectors are
2038 * tags.h (scm_tcs_bignums): Removed.
2039 (scm_tc16_bigpos, scm_tc16_bigneg): Replaced by scm_tc16_big.
2040 Use SCM_BIGSIGN(x) to test for sign!
2041 (scm_tc16_big): The new bignum type.
2042 (SCM_REAL_PART, SCM_IMAG_PART): Removed.
2044 * numbers.h (SCM_BIGSIGN): Sign moved to bit 16.
2045 (scm_makdbl): Deprecated.
2046 (SCM_NEWREAL, SCM_NEWCOMPLEX): New macros.
2047 (SCM_SINGP): Deprecated.
2049 (SCM_INEXP, SCM_CPLXP): Deprecated.
2050 (SCM_INEXACTP, SCM_COMPLEXP): New macros.
2051 (SCM_COMPLEX_REAL, SCM_COMPLEX_IMAG): Renamed from
2052 SCM_REAL, SCM_IMAG (and now only valid for complex numbers).
2053 (SCM_REAL, SCM_IMAG): New, *deprecated*, selectors which work both
2054 for doubles and complex numbers.
2055 (SCM_REAL_VALUE): New selector for doubles.
2056 (scm_double_t, scm_complex_t): New types.
2059 * numbers.c (scm_floprint, scm_floequal): Removed.
2060 (scm_print_real, scm_print_complex, scm_real_equalp,
2061 scm_complex_equalp): New functions.
2063 * unif.c (scm_makflo): Removed.
2065 * smob.h (SCM_SMOB_PREDICATE): New macro.

2067 SCM_RETURN_NEWSMOB3): New macros.
2069 1999-11-21 Michael Livshin <mlivshin@bigfoot.com>
2071 The following changes implement primitive support for double cells
2072 (i.e. four-word cells) and change the representation of some
2073 things to multi-cells instead of cons+malloc. (Applied and
2076 * pairs.h (SCM_NEWCELL2): double-cell variants of SCM_NEWCELL.
2077 (SCM_CELL_WORD, SCM_CELL_WORDLOC, SCM_SET_CELL_WORD): primitive
2078 multi-cell access macros (used by the ones below).
2079 (SCM_CELL_WORD[0-3], SCM_SET_CELL_WORD[0-3]): multi-cell access
2082 * gc.c (scm_freelist2): multi-cell freelists.
2083 (inner_map_free_list): map_free_list, parameterized on ncells.
2084 "nn cells in segment mm" was misleading for ncells > 1; changed to
2085 "objects". still print cells too, though.
2086 (scm_map_free_list): rewritten using inner_map_free_list.
2087 (scm_check_freelist): get freelist as parameter, since now we have
2089 (scm_debug_newcell2): multi-cell variants of
2091 (scm_gc_for_newcell): take ncells and freelist pointer as
2093 (scm_gc_mark): add case for tc7_pws (procedures with setters are
2095 (scm_gc_sweep): don't free the float data, since it's not malloced
2097 (init_heap_seg): didn't understand what n_new_objects stood for,
2098 so changed to n_new_cells.
2099 (make_initial_segment): new function, makes an initial segment
2100 according to given ncells.
2101 (scm_init_storage): call make_initial_segment, for ncells={1,2,3}.
2103 * numbers.c (scm_makdbl): no malloc'ing needed, so the
2104 {DEFER,ALLOW}_INTS thing removed.
2106 * numbers.h (struct scm_dbl): changed to represent a double cell,
2107 with the number in the second half.
2109 * dynwind.c: changed the wind-guards representation to double
2112 * procs.c, procs.h: changed the procedure-with-setter representation
2115 * async.c, async.h: made async representation a double cell.
2117 * dynl.c: made dynamic_obj representation a double cell.
2119 2000-03-13 Gary Houston <ghouston@arglist.com>
2121 * ports.c (flush_void_port): renamed to flush_port_default.
2122 (end_input_void_port): renamed to end_input_default.
2124 * init.c (scm_standard_stream_to_port): create a void port instead
2125 of opening /dev/null if the standard file descriptors are bad.
2126 advantages: no portability problems, doesn't waste a file descriptor,
2127 simplifies the code (thanks to Marius for the idea).
2129 * vports.c (s_scm_make_soft_port): call scm_port_non_buffer.
2131 * void ports: make reading from a void port give EOF instead of
2133 * ports.c (s_scm_sys_make_void_port): modified docstring.
2134 (fill_input_void_port): new proc.
2135 (scm_init_ports): set up fill_input_void_port.
2136 * ports.c (scm_port_non_buffer): new proc.
2137 (scm_void_port): call scm_port_non_buffer.
2139 * fports.c (scm_setvbuf): docstring: remove the fcntl documentation
2140 which was incorrectly appended.
2142 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2144 * guile-doc-snarf.in: Don't use absolute path for `sed'. (Note
2145 that we can't use autoconf for this. Autoconf itself relies on
2146 the existence of `sed' somewhere on your path.) (Thanks to Dirk
2149 2000-03-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2151 * Makefile.am (libguile_la_SOURCES): Moved iselect.c here from
2152 EXTRA_libguile_la_SOURCES.
2154 * iselect.h: Always declare scm_internal_select.
2156 * iselect.c (scm_internal_select): Added SCM_ASYNC_TICK at the
2157 end. Also let scm_internal_select be a real function also when
2160 * __scm.h (SCM_TICK): Oops! Forgot to put SCM_ASYNC_TICK here...
2162 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2164 * __scm.h (SCM_ALLOW_INTS, SCM_REALLOW_INTS): Removed call to
2165 SCM_ASYNC_TICK. (This is a preparation for POSIX threads support,
2166 and kind of an experiment: Will this cause problems?)
2168 Sun Mar 12 13:26:30 2000 Greg J. Badros <gjb@cs.washington.edu>
2170 * Makefile.am: Added *.doc to DISTCLEANFILES.
2172 2000-03-12 Gary Houston <ghouston@arglist.com>
2174 * fports.c (scm_fdes_to_port): call fcntl F_GETFL to test that
2175 the fdes is valid before doing anything else. check that
2176 the file descriptor supports the modes required.
2177 (scm_fport_buffer_add): don't throw an error if fstat doesn't
2178 work: just use the default buffer size.
2180 * throw.c: change an outdated comment about scm_internal_catch
2181 BODY: it doesn't take a jumpbuf arg.
2183 * init.c (scm_standard_stream_to_port): install a handler in case
2184 scm_fdes_to_port throws an error. don't check here whether the
2185 file descriptor is valid, since scm_fdes_to_port will do that.
2186 set the revealed count depending on whether the port got the
2187 standard file descriptor.
2188 (stream_body_data): new type.
2189 (stream_body, stream_handler): new procs.
2191 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2193 * stacks.c, stacks.h, struct.c, tags.h, unif.c (scm_bits_t):
2194 Renamed from SCMWORD.
2196 * tags.h (SCM_NCELLP): Removed (SCMWORD).
2198 * arbiters.c (SCM_ARB_LOCKED): Use SCM_UNPACK_CAR.
2200 * async.c, boolean.h, debug.c, dynl.c, dynwind.c, eval.c, eval.h,
2201 feature.h, filesys.h, fluids.h, fports.c, fports.h, gc.c, gc.h,
2202 hash.c, keywords.h, macros.c, numbers.c, numbers.h, objects.c,
2203 objects.h, options.c, pairs.h, ports.c, ports.h, print.c,
2204 procs.h, ramap.c, read.c, smob.c, smob.h, srcprop.h, stacks.c,
2205 stacks.h, strports.c, struct.c, struct.h, tag.c, tags.h,
2206 throw.c, unif.c, unif.h, variable.h, vectors.h, weaks.c,
2207 weaks.h (SCM_PACK, SCM_UNPACK, SCM_UNPACK_CAR): Renamed from
2208 SCM_ASSCM, SCM_ASWORD, SCM_CARW).
2210 * numbers.h (SCM_SRS, SCM_INUM): Corrected SCM_ASSCM/ASWORD fixes.
2212 * alist.c, eval.c, net_db.c, posix.c, print.c, snarf.h, struct.c,
2213 tags.h: Fixed copyright notices.
2215 * struct.c, coop-threads.c: SCM_ASSCM/ASWORD fixes.
2217 2000-03-12 Marius Vollmer <mvo@zagadka.ping.de>
2219 * init.c (scm_standard_stream_to_port): Check whether the file
2220 descriptor is valid and substitute "/dev/null" when not.
2222 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2224 * coop-defs.h (struct timespec): Conditionally defined.
2226 * coop.c (coop_condition_variable_timed_wait_mutex): Use ETIMEDOUT
2229 * readline.c (match_paren): Bugfix: First arg to select is not
2230 number of descriptors but the number of the highest descriptor +
2233 This is a preliminary attempt at a cleanup of the threads support
2234 code. It moves things to better places, makes arguments more
2235 consistent with the POSIX API (which is used in GNOME's glib), and
2236 adds new functionality.
2238 * readline.c (scm_init_readline): Added new arg to scm_init_mutex.
2240 * coop-defs.h (scm_mutex_trylock): New macro: alias for
2242 (scm_cond_init): Changed definition to
2243 coop_new_condition_variable_init.
2245 * coop.c: #include <errno.h>
2246 (coop_timeout_qinsert): Moved here from iselect.c
2247 (coop_new_mutex_init, coop_new_condition_variable_init): New
2248 functions. The strange names are temporary. Use scm_mutex_init
2249 and scm_cond_init instead.
2250 (coop_mutex_trylock): New function. Uses errno.h:EBUSY. errno.h
2251 is ANSI C, but should we check for individual error codes in
2253 (coop_condition_variable_timed_wait_mutex): New function.
2254 (coop_key_create, coop_setspecific, coop_getspecific,
2255 coop_key_delete): New functions.
2257 * iselect.c (coop_timout_qinsert): Moved to coop.c
2259 2000-03-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2261 * pairs.h (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR,
2262 SCM_SETOR_CDR): Corrected SCM_ASSCM/WORD fixes.
2264 * tags.h (SCM_VOIDP_TEST): Renamed from VOIDP_TEST.
2267 * objects.h (SCM_CLASS_FLAGS, SCM_OBJ_CLASS_FLAGS,
2268 SCM_SET_CLASS_INSTANCE_SIZE), struct.h (SCM_STRUCT_VTABLE_DATA),
2269 proc.h (SCM_CLOSCAR): SCM_ASSCM/WORD fixes.
2271 * eval.c (scm_lookupcar1): Inserted SCM_ASWORD in expressions
2274 2000-03-11 Dale P. Smith <dpsm@en.com>, applied by Greg J. Badros, <gjb@cs.washington.edu>
2276 * numbers.c (scm_copy_big_dec, scm_copy_smaller, scm_big_ior,
2277 scm_big_xor, scm_big_and, scm_big_test): Added new lowlevel bignum
2278 logical functions from SCM.
2280 (logand, logior, logxor, logtest, logbit?): Extended scheme
2281 logical functions to use bignums from SCM.
2283 (lognot): Removed call to `SCM_VALIDATE_INUM' that prevented
2284 lognot from using bignums.
2286 Thu Mar 9 11:33:25 2000 Greg J. Badros <gjb@cs.washington.edu>
2288 * vectors.h (SCM_VELTS_AS_STACKITEMS): Added this macro to help in
2289 eliminating some warnings.
2291 * unif.c, strports.c, print.c, options.c: Fix some warnings on
2294 * gc.c, gc.h: Added scm_return_first_int(), and added comment re:
2295 what the scm_return_first* functions do.
2297 2000-03-09 Han-Wen Nienhuys <hanwen@cs.uu.nl>, applied by Greg J. Badros, <gjb@cs.washington.edu>
2299 * libguile/*.[ch]: make a distinction between SCM as a generic
2300 name for a Scheme object (now a void*), and SCM as 32 bit word for
2301 storing tags and immediates (now a long int). Introduced
2302 SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious
2303 code in the process: arbiter.c (use macros), unif.c (scm_array_p),
2305 Wed Mar 8 10:15:59 2000 Greg J. Badros <gjb@cs.washington.edu>
2307 * numbers.c: Use SCM_VALIDATE_LONG_COPY, and longs, not ints, in
2308 various logXXX primitives. Thanks Eric Moore!
2310 Tue Mar 7 08:05:22 2000 Greg J. Badros <gjb@cs.washington.edu>
2312 * run-test, remaining-docs-needed: Added these scripts. The
2313 second one is only temporary until the docstring additions are
2314 complete. run-test may best live on, but is here mostly for
2315 convenience and awareness for now.
2317 * hash.c: Docs, minor cleanup patch from Dirk Herrman.
2319 Thu Mar 2 16:06:58 2000 Greg J. Badros <gjb@cs.washington.edu>
2321 * error.h, error.c: Added `scm_wrong_type_arg_msg' to support
2322 displaying the expected type. Use SCM_LISTn in a couple places
2323 instead of scm_cons-ing by hand.
2325 * __scm.h: Added SCM_ASSERT_TYPE macro.
2327 * validate.h, scm_validate.h: Added the former, as a renamed
2328 version of the latter with SCM_ASSERT_TYPE used in
2329 SCM_MAKE_VALIDATE (instead of just SCM_ASSERT)
2331 * Makefile.am: Rename scm_validate.h to validate.h.
2333 * *.c, *.h: Include validate.h, not scm_validate.h (old name's
2334 prefix was superfluous).
2336 Thu Mar 2 15:33:12 2000 Greg J. Badros <gjb@cs.washington.edu>
2338 * hashtab.c: Improved documentation for lots of functions. Added
2339 handwritten docs for `hash-fold'.
2341 Thu Mar 2 15:13:25 2000 Greg J. Badros <gjb@cs.washington.edu>
2343 * list.c: Added hand-written docs for `del{q,v,ete}1!'.
2345 Thu Mar 2 12:38:30 2000 Greg J. Badros <gjb@cs.washington.edu>
2347 * list.c: Moved append docs to append! Thanks Dirk Hermann. Also,
2348 added append docs from R4RS.
2350 * strings.c: Docstring typo fix, + eliminate unneeded IMP tests.
2351 Thanks Dirk Hermann!
2353 * chars.h: Provide SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR and
2354 deprecate SCM_ICHRP, SCM_ICHR, SCM_MAKICHR. Thanks Dirk Hermann!
2356 * *.h, *.c: Use SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR throughout.
2357 Drop use of SCM_P for function prototypes... assume an ANSI C
2358 compiler. Thanks Dirk Hermann!
2360 Sat Feb 19 12:20:12 2000 Greg J. Badros <gjb@cs.washington.edu>
2362 * ports.c: Made `set-port-column!' and `set-port-line!' each
2363 return SCM_UNSPECIFIED instead of a (not-scheme-object) integer
2364 that caused a seg fault. Also fixed `set-port-column!'s
2365 docstring. Thanks Han-Wen Nienhuys for finding the bug!
2367 Sun Feb 13 19:11:42 2000 Greg J. Badros <gjb@cs.washington.edu>
2369 * arbiters.c, eq.c, gc.c, guardians.c, list.c, ports.c, print.c,
2370 regex-posix.c, scmsigs.c, stime.c, strings.c, variable.c, stime.c,
2371 strings.c, variable.c: Added lots of documentation, cleaned up
2372 some existing documentation. Occasionally changed formal params
2373 to match docs. Also folded an #ifdef into the inners of a
2374 primitive instead of having two copies of the primitive
2375 (`get-internal-real-time', from stime.c)
2377 Sun Feb 13 18:12:19 2000 Greg J. Badros <gjb@cs.washington.edu>
2379 * ports.c: Added docs for primitives missing them. Written by
2382 Sun Feb 13 09:40:36 2000 Greg J. Badros <gjb@cs.washington.edu>
2384 * guile-doc-snarf.in: Use ${AWK} -f guile-func-name-check, not
2385 just execing guile-func-name-check. Thanks Michael Livshin!
2387 Thu Feb 10 11:43:23 2000 Greg J. Badros <gjb@cs.washington.edu>
2389 * guile-snarf.awk.in: Tweak to work with Sun/HP awk, removed some
2390 dead code. Patch from Michael Livshin.
2392 * guile-doc-snarf.in: Tweak to work with Sun/HP sh. Patch from
2395 2000-02-09 Gary Houston <ghouston@arglist.com>
2397 * init.c (scm_init_standard_ports): when stdout is a tty, make the
2398 current-output-port unbuffered by default. this is less confusing
2399 for interactive use. it was line-buffered because of a
2400 performance problem with unbuffered ports, but I think it will be
2403 2000-02-08 Gary Houston <ghouston@arglist.com>
2405 * __scm.h: don't define long_long or ulong_long if HAVE_LONG_LONGS
2408 * stime.c (scm_localtime, scm_mktime): if neither HAVE_TM_ZONE nor
2409 HAVE_TZNAME are defined, use an empty string instead of giving two
2410 spurious compile-time errors.
2412 Tue Feb 8 13:57:46 2000 Greg J. Badros <gjb@cs.washington.edu>
2414 * ports.c: Doc patches from Richard Kim. Pasted from MIT Scheme.
2417 Mon Feb 7 09:07:31 2000 Greg J. Badros <gjb@cs.washington.edu>
2419 * macros.c: Doc patches from Richard Kim. Pasted from scm.texi.
2421 Sun Feb 6 20:26:21 2000 Greg J. Badros <gjb@cs.washington.edu>
2423 * pairs.c: Doc patches from Richard Kim. Pasted from MIT Scheme
2424 (which is GNU GPL'd).
2426 2000-01-31 Gary Houston <ghouston@arglist.com>
2428 * strings.h: don't use SCM_P. don't include <string.h>.
2429 * error.c, gh_data.c, ports.c, script.c, strop.c: include <string.h>.
2431 * strings.c (scm_string_ref): make the 2nd argument compulsory.
2432 previously it defaulted to zero for no good reason that I can see.
2433 use a local variable for SCM_INUM (k). replace
2434 SCM_VALIDATE_INUM_DEF with SCM_VALIDATE_INUM_COPY.
2436 (scm_makfromstr): cosmetic changes.
2438 (scm_string): Accept only chars in the list, not strings, for
2439 conformance to R5RS (particularly for list->string, which is
2440 supposed to be the inverse of string->list.) remove
2441 SCM_DEFER_INTS/SCM_ALLOW_INTS, which is unnecessary since
2442 scm_makstr handles the cell allocation. when reporting wrong-type
2443 arg, don't report the position as 1.
2445 * posix.c (scm_init_posix): intern PIPE_BUF if it's defined.
2447 2000-01-29 Gary Houston <ghouston@arglist.com>
2449 * posix.c (scm_pipe): rewrote the docstring.
2451 * filesys.c (scm_select, retrieve_select_type, get_element,
2452 fill_select_type, set_element): modified so that Scheme
2453 "select" tests port buffers for the ability to provide input
2454 or accept output. Previously only the underlying file descriptors
2455 were checked. Rewrote the docstring.
2457 Thu Jan 27 10:14:25 2000 Greg J. Badros <gjb@cs.washington.edu>
2459 * vectors.c, symbols.c, strorder.c: Documentation cut and pasted
2460 from Gregg Reynolds. Thanks Gregg!
2462 Thu Jan 27 09:59:38 2000 Greg J. Badros <gjb@cs.washington.edu>
2464 * strop.c (scm_i_index): Obfuscated commented-out SCM_DEFINE by
2465 adding "x" prefix to the line so that guile-func-name-check
2466 doesn't complain unnecessarily.
2468 Wed Jan 26 17:33:52 2000 Greg J. Badros <gjb@cs.washington.edu>
2470 * throw.c: Factor out an #ifdef/#else/#endif choice more finely
2471 for maintainability.
2473 * strop.c: Documentation added by Gregg A. Reynolds. Pasted in
2476 Wed Jan 26 10:02:11 2000 Greg J. Badros <gjb@cs.washington.edu>
2478 * tag.c: Added doc for `tag', but mark as deprecated since Mikael
2479 suggests removing tag.c altogether (and using a new `class-of'
2482 * strings.c: Added documentation from Gregg A. Reynolds. Edited
2483 a bit by me to use FOO instead of @var{foo} and to have the
2484 summary come before preconditions on input. Also dropped trailing
2487 * gsubr.c: Do not use SCM_DEFINE for `gsubr-apply'. Register the
2488 function with scm_make_subr_opt w/ last arg of 0 so it is not
2489 visible at the Scheme level. Mikael says that this is the right
2490 thing because the first arg to the proc is the guts of a compiled
2491 closure and shouldn't be exposed to the Scheme level.
2493 Tue Jan 25 17:15:47 2000 Greg J. Badros <gjb@cs.washington.edu>
2495 * sort.c: typo in comment fixed.
2497 * keywords.c: Added documentation.
2499 * guardians.c: Added documentation (could be better).
2501 * gc.c: Added docs for gc-set-debug-check-freelist.
2503 * eq.c: Added docs for eq?, eqv? equal? abridged from R4RS.
2505 * boolean.c: Added docs for `not', `boolean?' (by hand).
2507 Tue Jan 25 13:28:56 2000 Greg J. Badros <gjb@cs.washington.edu>
2509 * random.c: Added documentation, from SLIB page:
2510 http://angela.ctrl-c.liu.se/~calle/scheme/slib_toc.html
2512 Mon Jan 24 17:50:20 2000 Greg J. Badros <gjb@cs.washington.edu>
2514 * variable.c, version.c: Added documentation, written by hand
2515 since I could not find anything already written that was
2518 2000-01-23 Gary Houston <ghouston@arglist.com>
2520 * filesys.c (scm_chown): omit port/fdes support if HAVE_FCHOWN is
2521 not defined (thanks to Richard Y. Kim).
2523 Thu Jan 20 13:00:38 2000 Greg J. Badros <gjb@cs.washington.edu>
2525 * Makefile.in: Removed, this is auto-generated.
2527 Thu Jan 20 11:33:47 2000 Dirk Hermann <dirk@ida.ing.tu-bs.de> --applied 01/20/00 gjb
2529 * list.c: Put some variable initialization code at the point of
2530 declaration; Added a comment for list*; Formatting changes.
2532 * load.c: use SCM_NNULLP to make sure the end of a list is not
2535 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2537 * backtrace.c (scm_display_error_message): Bugfix: Don't use
2538 result of scm_list_p as C boolean.
2539 (scm_display_error_message, scm_set_print_params_x): Use new
2540 validation macros. (Thanks to Dirk Herrmann.)
2542 * net_db.c (scm_resolv_error): Cast result from hstrerror.
2544 * strports.c (st_end_input): Inserted parenthesis to get operator
2547 * list.h (scm_init_list): Removed SCM_P around prototypes.
2549 * fports.c, list.c, numbers.c, ports.c, stime.c, symbols.c,
2550 filesys.c, posix.c: Converted docstrings to ANSI C format and
2551 escaped " occurring inside string literals.
2553 Tue Jan 18 13:21:08 2000 Mikael Djurfeldt <mdj@r11n07-s.pdc.kth.se>
2555 * posix.c (scm_mknod): Escape " occuring inside docstring.
2557 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2559 * alist.c, chars.c, debug.c, dynl.c, dynwind.c, error.c, eval.c,
2560 evalext.c, filesys.c, gc.c, hash.c, hashtab.c, ioext.c,
2561 keywords.c, list.c, load.c, macros.c, net_db.c, numbers.c,
2562 objprop.c, ports.c, posix.c, print.c, procprop.c, procs.c,
2563 ramap.c, regex-posix.c, root.c, scmsigs.c, simpos.c, socket.c,
2564 stacks.c, stime.c, strings.c, strop.c, strports.c, struct.c,
2565 symbols.c, throw.c, unif.c, vectors.c, version.c, vports.c,
2566 weaks.c: Converted docstrings to ANSI C format.
2568 * filesys.c (scm_chmod), simpos.c (scm_system), version
2569 (scm_version), vports (scm_make_soft_port): Escape " occuring
2572 Mon Jan 17 11:41:22 2000 Greg J. Badros <gjb@cs.washington.edu>
2574 * scm_validate.h: Added SCM_VALIDATE_ULONG_COPY,
2575 SCM_VALIDATE_LONG_COPY
2577 * numbers.c: Use SCM_VALIDATE_ULONG_COPY, instead of
2578 SCM_VALIDATE_INUM_COPY to let bigger numbers be used. Rename a
2579 couple of formal arguments (and fix their uses) to make arguments
2580 match the documentation.
2582 2000-01-14 <mstachow@alum.mit.edu>
2584 * Makefile.am: Augment path when running guile-doc-snarf so
2585 guile-func-name-check is found.
2587 Fri Jan 14 09:34:55 2000 Greg J. Badros <gjb@cs.washington.edu>
2589 * scm_validate.h (SCM_NUM2LONG_DEF): Fix this macro to just use
2590 def, not SCM_MAKINUM(def); thanks Janis Bzerins!
2592 Wed Jan 12 00:06:53 2000 Greg J. Badros <gjb@cs.washington.edu>
2594 * net_db.c (s_scm_inet_makeaddr): Use SCM_NUM2ULONG since that's
2595 the way guile-1.3.4 worked, but #if 0 out the version using
2596 SCM_VALIDATE_INUM_COPY for stricter testing.
2598 Tue Jan 11 18:24:18 2000 Greg J. Badros <gjb@cs.washington.edu>
2600 * guile-doc-snarf.in: Use new $fullfilename for running
2601 guile-func-name-check, and put "$fullfilename" and "$filename" in
2602 quotes at uses to make sure re-splitting on whitespace does not
2603 occur (so filenames w/ embedded whitespace would work okay, though
2604 I sure hope we never have to deal with that! :-) ). Thanks to
2605 Mikael for pointing out the source_dir != build_dir was broken.
2607 Tue Jan 11 17:42:40 2000 Greg J. Badros <gjb@cs.washington.edu>
2609 * scm_validate.h: Added SCM_NUM2LONG_DEF macro. Make
2610 SCM_OUT_OF_RANGE use SCM_MAKINUM, not scm_long2num. Added
2611 SCM_COERCE_ROSTRING macro. Added SCM_VALIDATE_NONEMPTYLIST
2612 macro. Fix SCM_VALIDATE_STRINGORSUBSTR macro to not use SLOPPY
2615 * ports.c (scm_port_closed_p): Validate that the arg is a PORT,
2616 then return whether it's an open port (was validating that it was
2617 an open port -- this was a bug I introduced back in December, but
2618 my careful reading of diffs caught it).
2620 * numbers.c: Recombine the two conditional-compilation paths for
2621 all the log* primitives -- they were split based on #ifndef
2622 scm_long2num; factored out a SCM_LOGOP_RETURN macro, and fixed
2623 some bugs and inconsistencies in the two sets of implementations.
2624 (scm_lognot) Fixed *atrocious* re-use of a SCM as an integer!
2626 * ioext.c: Use SCM_ASSERT_RANGE in a couple places, and
2627 SCM_VALIDATE_INUM_COPY once where it should've been used.
2629 * fluids.c (scm_internal_with_fluids): Use
2630 SCM_VALIDATE_LIST_COPYLEN.
2632 * filesys.c: Use SCM_NUM2LONG instead of SCM_VALIDATE_INUM_COPY;
2633 this is questionable as it relaxes type safety, but other changes
2634 were useful and all SCM_NUM2LONG's should probably be
2635 revisited. Use SCM_OUT_OF_RANGE, SCM_WRONG_TYPE_ARG.
2637 * evalext.c: line-break change on 1 line.
2639 * eval.c (nconc2last): Takes a non-empty list as its first
2640 argument, not just a list.
2642 * dynl.c: Use new SCM_COERCE_ROSTRING macro.
2644 Tue Jan 11 15:44:23 2000 Greg J. Badros <gjb@cs.washington.edu>
2646 * dynl.c, feature.c, filesys.c, fports.c, list.c, load.c,
2647 net_db.c, sort.c, stacks.c, unif.c: Use SCM_WTA, SCM_MISC_ERROR
2650 * symbols.c (scm_sysintern0): Fixed the function name in a
2651 scm_misc_error invocation.
2653 * print.c (scm_simple_format): Do not need SCM_COERCE_SUBSTR, and
2654 use scm_return_first to ward off latent GC bug that Mikael caught.
2656 * async.c: Use SCM_VALIDATE_ASYNC_COPY one place where it wasn't
2657 used before but should've been.
2659 2000-01-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2661 * snarf.h (SCM_PROC1): Replaced SCM (*) (...) with
2662 SCM_FUNC_CAST_ARBITRARY_ARGS.
2664 Tue Jan 11 13:44:07 2000 Greg J. Badros <gjb@cs.washington.edu>
2666 * guile-func-name-check.in: Added this script to statically check
2667 #define FUNC_NAME, #undef FUNC_NAME in the source.
2669 * sort.c, posix.c: Fix #undef FUNC_NAME lines to not have trailing
2670 redundant comment, semicolon; caught by new guile-func-name-check
2673 * debug.c: Fix mistaken #define FUNC_NAME for scm_make_iloc.
2674 Caught by new guile-func-name-check-script.
2676 * Makefile.am: Added guile-func-name-check to bin_SCRIPTS
2678 * ramap.c: Fix #if 0'd out code to be syntactically acceptable to
2679 guile-func-name-check.
2681 * guile-doc-snarf.in: Run guile-func-name-check on the file before
2684 Tue Jan 11 11:31:10 2000 Greg J. Badros <gjb@cs.washington.edu>
2686 * fports.c, ports.c, ports.h, strports.c, vports.c: Make write
2687 port function take const void*, not void*.
2689 Tue Jan 11 11:18:07 2000 Greg J. Badros <gjb@cs.washington.edu>
2691 * scm_validate.h, chars.c, ports.c, print.c, read.c, strings.c,
2692 strop.c: Use SCM_VALIDATE_ICHR, SCM_VALIDATE_ICHR_COPY instead of
2693 SCM_VALIDATE_CHAR, SCM_VALIDATE_CHAR_COPY. Change made for
2694 consistency with the other macros dealing with immediate
2695 characters. (Similar to INT -> INUM change a week or so ago).
2697 Tue Jan 11 10:41:46 2000 Greg J. Badros <gjb@cs.washington.edu>
2699 * dynl.c, error.c, eval.c, feature.c, filesys.c, fports.c, list.c, load.c,
2700 net_db.c, read.c, socket.c: Update error messages to use ~A for
2701 %s, ~S for %S to work with new `simple-format' format and be
2702 standardized better.
2704 * print.h, print.c (scm_simple_format): Added `simple-format'
2705 primitive. It's the old scm_display_error, with ARGS now a rest
2706 parameter, and the destination first instead of last (and a couple
2707 new capabilities inspired by `format' -- #t as destination means
2708 current-output-port, #f means return the formatted text as a
2711 * gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
2713 * backtrace.c (scm_display_error_message): Rewrote to use
2714 scm_simple_format() procedure.
2716 * __scm.h: Added commented-out #define of GUILE_DEBUG_FREELIST
2718 2000-01-09 Marius Vollmer <mvo@zagadka.ping.de>
2720 Finally applied the libltdl patch from Thomas Tanner, with slight
2723 * DYNAMIC-LINKING: Removed because it is obsolete.
2724 * dynl.c: Use ANSI prototypes.
2725 (sysdep_dynl_link): Use lt_dlopenext instead of lt_dlopen.
2726 * scmconfig.h.in: Do not change, as it is automatically generated.
2728 1999-07-25 Thomas Tanner <tanner@ffii.org>
2730 * dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c: deleted
2732 * Makefile.am: likewise, add INCLTDL (libltdl headers) to
2733 INCLUDES, set dlpreopened files in LDFLAGS, link libguile
2735 * dynl.c: use libltdl if DYNAMIC_LINKING is enabled,
2736 * guile.c: register preloaded modules
2737 * scmconfig.h.in: remove obsolete symbols
2739 2000-01-09 Gary Houston <ghouston@arglist.com>
2741 * These changes should make it unnecessary to call tzset from
2742 Scheme after modifying the TZ environment variable, even if the
2743 system date facilities cache the value.
2744 * stime.c (setzone, scm_localtime): added comments.
2745 (tzset): don't define a noop tzset macro if HAVE_TZSET not defined.
2746 (setzone): don't call tzset.
2747 (restorezone): call tzset only if HAVE_TZSET is defined.
2748 (scm_tzset): don't define if HAVE_TZSET not defined. Change the
2749 doc string to indicate that this procedure isn't likely to do
2751 (scm_localtime, scm_strftime, scm_mktime): call tzset if
2752 LOCALTIME_CACHE is defined.
2754 2000-01-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2756 * posix.c (scm_sync): Return SCM_UNSPECIFIED.
2758 2000-01-09 Gary Houston <ghouston@arglist.com>
2760 * eval.c: define scm_unbound_variable_key ('unbound-variable).
2761 scm_lookupcar1: throw an error with key 'unbound-variable instead
2762 of 'misc-error when an unbound variable is encountered.
2764 * filesys.c (scm_mkdir, scm_rmdir, scm_getcwd, scm_select,
2765 scm_symlink, scm_readlink, scm_lstat),
2766 posix.c (scm_setpgid, scm_setsid, scm_ctermid, scm_tcgetpgrp,
2767 scm_tcsetpgrp, scm_uname, scm_setlocale, scm_mknod, scm_nice,
2769 simpos.c (scm_system),
2770 stime.c (scm_times, scm_strptime):
2771 move the HAVE_XXX feature tests out of the procedure bodies.
2772 don't use SCM_SYSMISSING.
2773 scm_validate.h (SCM_SYSMISSING): removed.
2774 error.h, error.c (scm_sysmissing): comment that this is deprecated.
2775 see ChangeLog entry for 1999-12-28.
2777 Sat Jan 8 19:52:04 2000 Greg J. Badros <gjb@cs.washington.edu>
2779 * scm_validate.h (SCM_VALIDATE_BOOL_COPY): Fix typo.
2781 Sat Jan 8 17:06:46 2000 Greg J. Badros <gjb@cs.washington.edu>
2783 * backtrace.c: Fix spelling typo in a comment.
2785 * snarf.h: Use new SCM_DOCS macro to encapsulate the non SCM_INIT
2786 text. Reformatted some of the expansions.
2788 Fri Jan 7 15:50:46 2000 Greg J. Badros <gjb@cs.washington.edu>
2790 * scm_validate.h (SCM_OUT_OF_RANGE): Use scm_out_of_range_pos to
2791 report the position of the argument.
2793 * error.h, error.c (scm_out_of_range_pos): Added this function to
2794 take extra "pos" argument, the position number of the errant
2797 * debug.c: Use SCM_OUT_OF_RANGE instead of scm_out_of_range.
2799 * snarf.h: Use SCM_HERE and SCM_INIT as names, not SCM_NOTSNARF
2800 and SCM_SNARFING. Also put the %%% in the SCM_INIT since Mikael
2801 prefers that and I'm reasonably indifferent.
2803 Fri Jan 7 15:03:32 2000 Greg J. Badros <gjb@cs.washington.edu>
2805 * snarf.h: Factor out differences between C++ and non-C++ into
2806 SCM_FUNC_CAST_ARBITRARY_ARGS macro. Modify all the snarf macro
2807 definitions to use SCM_NOTSNARF and SCM_SNARFING macros (like
2808 Mikael's macros, below, but changed names and SCM_SNARFING no
2809 longer expands to include %%% -- that must appear in the argument
2810 so that the token appears at the call-site as a reminder).
2812 2000-01-07 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2814 * snarf.h (SCM_INSITU, SCM_INIT): New snarf macros for use in user
2815 snarf macro definitions.
2817 2000-01-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2819 * chars.c (scm_integer_to_char): Use Greg's nice
2820 SCM_VALIDATE_INUM_RANGE macro for argument checking for closer
2823 Thu Jan 6 11:48:49 2000 Greg J. Badros <gjb@cs.washington.edu>
2825 * *.c, snarf.h: Replace GUILE_PROC1 with SCM_DEFINE1 throughout.
2827 Thu Jan 6 11:22:53 2000 Greg J. Badros <gjb@cs.washington.edu>
2829 * Makefile.am (ETAGS_ARGS): Switch to SCM_DEFINE, SCM_DEFINE1
2830 instead of GUILE_PROC.
2832 Thu Jan 6 11:21:49 2000 Greg J. Badros <gjb@cs.washington.edu>
2834 * alist.c: Do not report mismatch errors on some uses of `tmp' (do
2835 this by using SCM_ARG2 instead of `2' in the SCM_VALIDATE_CONS
2838 Thu Jan 6 09:54:33 2000 Dirk Herrmann <dirk@ida.ing.tu-bs.de> --gjb applied
2840 * scm_validate.h: Remove some redundant NIMP tests.
2842 * alist.c: minimize scope of the tmp variables, and initialize
2843 them when declared. The strange SCM_NIMP tests are replaced by
2844 SCM_CONSP tests that more closely reflect the intended semantics.
2845 However, we don't get a performance penalty here, because the
2846 SCM_CONSP test was performed by the ALISTCELL test anyway. * The
2847 extremely ugly use of ASRTGO macros was removed: The calls to
2848 ASRTGO were not encapsulated by "#ifndef SCM_RECKLESS", but got a
2849 label parameter that only exists when SCM_RECKLESS is not defined.
2850 This works, because ASRTGO itself is defined in a way that it only
2851 makes use of the label parameter if SCM_RECKLESS is not defined
2852 (shudder!). Does guile make at all use of the possibility to
2853 define SCM_RECKLESS? * Codesize is likely to be reduced, since
2854 instead of two calls to SCM_ASSERT performed by the ALISTCELL test
2855 we now only get one test.
2857 * list.c: Use SCM_NNULLP, not SCM_NIMP as appropriate. Also use
2858 SCM_NULLP instead of SCM_IMP. Drop use of "register" keyword on
2859 some variables in `list?'. Fix `reverse' and `reverse!'
2860 primitives to handle improper lists better.
2862 Wed Jan 5 11:24:53 2000 Greg J. Badros <gjb@cs.washington.edu>
2864 * *.[ch]: Whitespace changes -- added space after SCM_VALIDATE_*
2865 macros and SCM_DEFINE macros to match GNU coding standards.
2867 Wed Jan 5 11:04:24 2000 Greg J. Badros <gjb@cs.washington.edu>
2869 * *.[ch]: Replace GUILE_PROC w/ SCM_DEFINE.
2871 Wed Jan 5 10:59:06 2000 Greg J. Badros <gjb@cs.washington.edu>
2873 * *.[ch]: Replace SCM_VALIDATE_INT w/ SCM_VALIDATE_INUM for
2874 better consistency with the names of other SCM_VALIDATE_ macros
2875 and better conformance to guile naming policy.
2877 Wed Jan 5 10:50:39 2000 Greg J. Badros <gjb@cs.washington.edu>
2879 * ports.c (s_scm_close_all_ports_except): Use SCM_ARG1 in a
2880 SCM_VALIDATE instead of 1 to avoid a check on the argument (since
2881 it's not the actual name of the formal).
2883 * guile-snarf.awk.in: Do argument/number mismatch checking and
2884 print warnings in an Emacs compile-mode parseable format.
2886 * struct.c: Use SCM_ASSERT_RANGE instead of SCM_ASSERT w/
2887 SCM_OUTOFRANGE as 3rd argument.
2889 * random.c: Fix argument/number mismatch (that I introduced :-( ).
2891 * __scm.h: Do not #define SCM_ARG* when snarfing;
2892 lets us distinguish between 1 and SCM_ARG1 when snarfing as only
2893 the former (using the number) requires the argument to match the
2894 formal in the current argument snarfing check.
2896 * snarf.h: Give new definition of SCM_ASSERT when in
2897 snarfing mode to output a lexically-identifiable sequence that the
2898 guile-snarf.awk script uses to verify argument/position matching.
2900 * ramap.c: Remove extraneous #undef FUNC_NAME.
2902 Wed Jan 5 08:36:38 2000 Greg J. Badros <gjb@cs.washington.edu>
2904 * guile-doc-snarf.awk.in: Removed -- guile-snarf.awk.in is the
2905 current version of the same functionality; it writes the .x output
2906 to stdout instead of directly into the file.
2908 Wed Jan 5 08:15:04 2000 Greg J. Badros <gjb@cs.washington.edu>
2910 * unif.c, symbols.c, strings.c, stacks.c, random.c, print.c,
2911 posix.c: Eliminated a bunch of SCM_NIMP(..)s that are now
2912 redundant with the safer macros. Patch from Dirk Hermann applied
2913 by hand. Thanks Dirk!
2915 * scm_validate.h: Added SCM_VALIDATE_VECTOR_OR_DVECTOR for some
2918 * ramap.c: whitespace change.
2920 Tue Jan 4 14:21:35 2000 Greg J. Badros <gjb@cs.washington.edu>
2922 * options.c, objects.c, keywords.c, gc.c: Some redundant SCM_NIMP
2923 removals from Dirk Hermann.
2925 * alist.c: Rename formals to match the parameter names in the
2926 documentation, updates to documentation. Thanks Dirk Hermann!
2928 2000-01-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2930 * eval.c (SCM_CEVAL): Reverse order of
2931 scm_stack_checking_enabled_p and SCM_STACK_OVERFLOW_P
2932 (Thanks to Brad Knotwell.)
2934 Mon Jan 3 08:30:02 2000 Greg Harvey <Greg.Harvey@thezone.net> (applied --01/03/00 gjb)
2936 * gc.c (scm_debug_newcell): Added SCM_SETCAR of the newly
2939 * pairs.h: Added a comment about the need for the SCM_SETCAR in
2942 Mon Jan 3 08:25:19 2000 Greg J. Badros <gjb@cs.washington.edu>
2944 * dynl-vms.c, debug.c, coop-threads.c, backtrace.c, eval.c: More
2945 SCM_NIMP tests that were redundant are now eliminated. Patches
2946 from Dirk Hermann applied by hand.
