1 2000-12-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
3 * print.c (scm_iprin1): Use scm_tc3_* codes instead of hardcoded
4 values. Added comment about tc3 codes that may appear in
5 immediates. Got rid of one goto command.
7 2000-12-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
9 * dynl.c (sysdep_dynl_link): Improved error reporting.
11 * guardians.c: Changed the representation from a compiled closure
12 to an applicable smob.
14 (guard1, CCLO_G): Removed.
16 (guard, g_mark, g_print, scm_tc16_guardian, scm_guardian_gc_init,
17 scm_guardian_zombify): Renamed to guardian_apply, guardian_mark,
18 guardian_print, tc16_guardian, guardian_gc_init and
19 guardian_zombify, respectively.
21 (guardian_free): Added, fixes a memory leak.
23 (guardian_print): Don't use sprintf hack.
25 (guardian_apply, scm_guard, scm_get_one_zombie,
26 scm_make_guardian): Don't use a compiled closure.
28 (guardian_zombify): Prefer !SCM_NULLP over SCM_NIMP. No need to
29 use SCM_GCCDR any more. Simplified loop condition.
31 (scm_init_guardian): Don't use scm_make_smob_type_mfpe for smob
32 initialization. Initialize applicable smob.
34 2000-12-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
36 * chars.c (scm_char_eq_p): Minor cleanup/optimization.
38 * gc.c (scm_gc_mark): Don't use SCM_VELTS for CCLOs.

48 2000-12-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
50 * list.[ch] (scm_c_memq): Added as a fast C level alternative for
51 scm_memq for the case that the list parameter is known to be a
54 * goops.c (filter_cpl, remove_duplicate_slots, applicablep),
55 goops.h (SCM_SUBCLASSP): Use scm_c_memq if we are sure that we
58 2000-12-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
60 * goops.c (scm_sys_compute_slots, scm_i_get_keyword,
61 scm_get_keyword, scm_slot_ref_using_class,
62 scm_slot_set_using_class_x): Update the code to match guile's
63 current style (e. g. using SCM_DEFINE, adding comments, removing
64 unnecessary SCM_NIMP tests etc.).
66 2000-11-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
68 Thanks to Julian Satchell for the bug report:
70 * coop-threads.c (scm_join_thread): Check whether a thread is
71 finished before trying to join it.
73 * coop.c (coop_aborthelp, coop_join): When a thread finishes, its
74 stack base is not set to NULL any more.
76 2000-11-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
78 * strop.c (scm_i_index): Removed outdated comment.

87 (SCM_SYMBOL_UCHARS): Removed.
89 2000-11-26 Gary Houston <ghouston@arglist.com>
91 * reimplementation of values, call-with-values as primitives:
93 * values.c, values.h: new files. use a struct to contain multiple
94 values, similar to the previous Scheme-level implementation.
95 * Makefile.am: add values.c, values.h, values.x.
96 * continuations.c (continuation_apply): support R5RS multiple value
98 * init.c: call scm_init_values.
99 * struct.h: define SCM_SET_STRUCT_PRINTER.
101 2000-11-25 Gary Houston <ghouston@arglist.com>
103 * use an applicable SMOB to represent continuations, instead of a
104 custom tc7 type. This will make it easier to support R5RS
105 multiple value continuations, without the use of a Scheme-level
108 * continuations.c (scm_tc16_continuation, continuation_mark,
109 continuation_free, continuation_print, continuation_apply):
111 (scm_make_continuation): new procedure, replaces scm_make_cont
112 with a different interface.
113 (copy_stack_and_call, scm_dynthrow, scm_init_continuations): rewritten.
114 (CHEAP_CONTINUATIONS): removed non-working code completely.
115 (scm_call_continuation): removed.
116 * continuations.h (struct scm_contregs): add num_stack_items and
117 stack fields. previously stack was stored following this struct:
118 use a tail array instead.
119 (SCM_CONTINUATIONP): new macro.
120 (SCM_CONTINUATION_LENGTH, SCM_SET_CONTINUATION_LENGTH):
122 (SCM_SET_CONTREGS): removed.
123 * tags.h: removed scm_tc7_contin (was tag 61).
124 * debug.c, gc.c, hash.c, print.c, procprop.c, procs.c:
125 removed scm_tc7_contin support.
126 * eval.c: use scm_make_continuation instead of scm_make_cont.
127 don't set jump buffers here. remove scm_tc7_contin support.
128 * init.c, root.c: create SMOB continuation for rootcont instead
129 of scm_tc7_contin. call scm_init_continuations before
131 * root.c: remove support for static jmpbuf. It's not used by
132 default and I broke it. create SMOB continuation for rootcont.
133 * stacks.c: use SCM_CONTINUATIONP.
135 2000-11-24 Matthias Koeppe <mkoeppe@mail.math.uni-magdeburg.de>
137 * goops.c (filter_cpl, remove_duplicate_slots), goops.h
138 (SCM_SUBCLASSP): Fix previous change: In contrast to
139 scm_sloppy_memq the function scm_memq returns #f if the
140 object was not contained in the list.
142 2000-11-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
144 * goops.c: Include validate.h.
146 (DEFVAR, scm_add_method): Don't use deprecated scm_eval2.
148 (scm_sys_fast_slot_ref, scm_sys_fast_slot_set_x,
149 scm_m_atdispatch): Provide FUNC_NAME definition. Don't use
150 deprecated SCM_OUTOFRANGE macro.
152 (scm_sloppy_num2ulong, scm_sys_logand): Removed. Guile's logand
153 function now provides the desired behaviour.
155 * goops.c (filter_cpl, remove_duplicate_slots), goops.h
156 (SCM_SUBCLASSP): Don't use deprecated scm_sloppy_memq.
158 2000-11-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
160 * symbols.h (SCM_LENGTH_MAX): Deprecated.
162 * unif.c (scm_make_uve): Use SCM_BITVECTOR_MAX_LENGTH and
163 SCM_UVECTOR_MAX_LENGTH instead of SCM_LENGTH_MAX. Postpone length
164 checks for strings and vectors to their constructors. Eliminate
165 redundant SCM_IMP test.
167 (scm_dimensions_to_uniform_array): Postpone length checks to
170 * unif.h (SCM_BITVECTOR_MAX_LENGTH, SCM_UVECTOR_MAX_LENGTH):

200 SCM_SET_BITVECTOR_LENGTH): Added.
202 * symbols.h (SCM_SETLENGTH): Deprecated.
204 2000-11-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
206 * continuations.c (scm_make_cont): Use
207 SCM_SET_CONTINUATION_LENGTH instead of SCM_SETLENGTH.
209 * continuations.h (SCM_SET_CONTINUATION_LENGTH): Added.
211 2000-11-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
213 * vectors.c (scm_make_vector), weaks.c (scm_make_weak_vector):
214 Use SCM_SET_VECTOR_LENGTH instead of SCM_SETLENGTH.
216 * vectors.h (SCM_SET_VECTOR_LENGTH): Added.

222 (scm_hasher), load.c (scm_parse_path, scm_search_path,

233 (scm_make_struct_layout), symbols.c (scm_string_to_symbol,
234 scm_string_to_obarray_symbol, scm_gensym, scm_gentemp): Replace
235 calls to SCM_ROU?CHARS with the corresponding call to
238 * symbols.h (SCM_ROCHARS, SCM_ROUCHARS): Deprecated.
240 2000-11-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
242 * ports.c: Include eval.h.
244 * strings.c (scm_string_set_x), strings.h (SCM_RWSTRINGP),

246 SCM_VALIDATE_RWSTRING.
248 * strings.h (SCM_STRING_UCHARS, SCM_STRING_CHARS): Handle strings
249 and substrings uniformly. However, substring handling is
252 (SCM_RWSTRINGP): Deprecated.
254 2000-11-18 Gary Houston <ghouston@arglist.com>
256 * Makefile.am (.c.x): don't prefix ".:" to $PATH when running
257 guile-doc-snarf. it doesn't seem to do anything useful, but would
258 fail if $PATH contained whitespace. Thanks to Lars J. Aas.
260 2000-11-17 Marius Vollmer <mvo@zagadka.ping.de>
262 * alist.c, arbiters.c, async.c, backtrace.c, boolean.c, chars.c,
263 continuations.c, debug-malloc.c, debug.c, dynl.c, dynwind.c,
264 environments.c, eq.c, error.c, eval.c, evalext.c, feature.c,

274 version.c, vports.c, weaks.c: Makes sure the snarfer output
275 inclusion is disabled when the snarfer is run on the file. Thanks
278 * Makefile.am: Install guile-procedures.txt in version-specific
279 directory to enable multiple installed guile versions. Suggested
280 by Karl M. Hegbloom <karlheg@debian.org, patch by Matthias Koeppe.
282 2000-11-13 Gary Houston <ghouston@arglist.com>
284 * fports.c: include gc.h.
285 (fport_flush, fport_close): silently ignore I/O errors when
286 closing a port during gc. it's better than aborting in scm_error.
288 * throw.c (scm_handle_by_message): remove obsolete comment.
290 2000-11-12 Gary Houston <ghouston@arglist.com>
292 * fports.c (scm_open_file): fix the 'b' option. Thanks
295 2000-11-09 Gary Houston <ghouston@arglist.com>
297 * ports.c, ports.h (scm_close_all_ports_except): deprecated.
298 use port-for-each. Updated its docstring.
300 2000-11-07 Gary Houston <ghouston@arglist.com>
302 * ports.c (scm_port_for_each): new proc. implements port-for-each,
303 which applies a procedure to each port in the port table.
304 ports.h: declare scm_port_for_each.
306 * ioext.c (scm_dup2): new proc. implements "dup2" which is a simple
307 wrapper for the dup2 system call (unlike dup->fdes or
308 primitive-move->fdes).
309 * ioext.h: declare scm_dup2.
311 * filesys.c (scm_close_fdes): new proc. implements "close-fdes"
312 which is a simple wrapper for close system call (unlike scm_close).
313 * filesys.h: declare for scm_close_fdes.
315 2000-11-06 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
317 * eval.c (SCM_IM_DISPATCH), objects.c (scm_mcache_lookup_cmethod):
318 Count n_specialized + 1 turns before letting a match through.
320 * goops.c (scm_sys_invalidate_method_cache_x): Don't convert
321 scm_si_n_specialized from fixnum and don't take absolute value.
322 (Thanks to Lars J. Aas.)
324 2000-11-04 Gary Houston <ghouston@arglist.com>
326 * ports.c (scm_port_p): new function, implements "port?" which
327 is mentioned in R5RS.
328 * ports.h: declare scm_port_p.
330 2000-11-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
332 * backtrace.c (display_expression, display_error_body), fports.c
333 (prinfport), print.c (scm_iprin1): Test for symbols and strings
334 explicitly instead of using SCM_ROSTRINGP.
336 * backtrace.c (scm_display_error_message): Don't pass a symbol to
337 scm_simple_format. Prefer high-level output functions.
339 (display_error_body): When displaying procedure names, give
340 preference to the name passed as a parameter. Only if none is
341 given extract a name from the stack information.
343 * fports.c (scm_fdes_to_port, prinfport), gc.c (scm_gc_mark),
344 ports.c (scm_port_filename, scm_set_port_filename_x): Use
347 * gh_data.c (gh_set_substr, gh_scm2newstr, gh_get_substr,
348 gh_symbol2newstr): Use scm_remember instead of a pair of calls to
349 scm_protect/unprotect_object.
351 * goops.c (make_struct_class), objects.c (scm_class_of): Struct
352 table names are symbols.
354 * ports.h (SCM_SET_FILENAME): Added.
356 * print.c (scm_iprin1): Don't use scm_puts to write symbols or
357 strings in order to treat substrings right. Reposition call to
358 scm_remember after the last use of object's data.
360 (scm_simple_format): Treat messages that are substrings right.
362 * symbols.h (SCM_ROSTRINGP): Deprecated.
364 2000-11-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
366 * environments.c (obarray_replace, obarray_retrieve,
367 obarray_remove): Don't use '==' to compare SCM objects.
369 * posix.c (scm_getgroups): Don't create a redundant string.
371 2000-11-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
373 * symbols.c (scm_sym2vcell, scm_sym2ovcell_soft,
374 scm_intern_symbol, scm_unintern_symbol): Symbol objects already
375 hold their hash values, no need to recompute them.
377 (scm_intern_obarray_soft): Speed up search for a matching symbol
378 by comparing the hash values first.
380 2000-10-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
382 * unif.c (scm_make_uve, scm_dimensions_to_uniform_array): Don't
383 allow vectors longer than SCM_LENGTH_MAX. This removes the
384 SCM_HUGE_LENGTH trick, i. e. storing a vector length greater than
385 SCM_LENGTH_MAX at the beginning of the vector's memory. Since not
386 all of guile's code was implemented to be aware of this trick, it
387 is unlikely that it was used anyway. We can implement such a
388 feature more cleanly by using double cells for uniform vector
391 (scm_shap2ra): Replace SCM_IMP and SCM_NIMP tests by more
392 straightforward predicates.
394 (scm_dimensions_to_uniform_array): Require that for dimensions
395 given as lower-bound/upper-bound pairs the upper-bound is never
396 less than the lower bound.
398 2000-10-27 Dirk Herrmann <D.Herrmann@tu-bs.de>

417 strports.c (scm_mkstrport), symbols.c
418 (scm_string_to_obarray_symbol), vports.c (scm_make_soft_port):
419 Don't accept symbols as input parameters. Use SCM_STRING_LENGTH
420 instead of SCM_ROLENGTH.

423 (scm_error_scm), filesys.c (scm_chown, scm_chmod, scm_open_fdes,

433 (setzone, scm_strftime, scm_strptime), vports.c
434 (scm_make_soft_port): Use SCM_STRING_COERCE_0TERMINATION_X to
435 make sure the characters of a string are followed by a \0.
436 Further, use SCM_STRING_CHARS instead of SCM_ROCHARS on the
439 * dynl.c (scm_make_argv_from_stringlist), posix.c
440 (scm_convert_exec_args): Aligned to match each other.
442 * dynl.c (scm_coerce_rostring): Removed.
444 (scm_dynamic_func): Changed the comment to reflect that the
445 function name has to be a string. Further, hide implementation
446 details from the scheme comment.
448 * error (scm_error_scm): Don't accept a symbol as message
449 parameter. Fix substring handling.
451 * posix.c (environ_list_to_c): Use memcpy to copy environment
452 strings. Handle substrings which don't have a trailing \0.
454 * symbols.h (SCM_LENGTH, SCM_ROLENGTH, SCM_SUBSTRP,
455 SCM_SUBSTR_STR, SCM_SUBSTR_OFFSET, SCM_COERCE_SUBSTR):
458 * unif.h (SCM_HUGE_LENGTH): Deprecated.
460 * validate.h (SCM_VALIDATE_ROSTRING, SCM_VALIDATE_ROSTRING_COPY,
461 SCM_VALIDATE_NULLORROSTRING_COPY): Deprecated.
463 2000-10-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
465 * random.c: Include unif.h.
467 * strings.h (SCM_STRING_COERCE_0TERMINATION_X): Added. This is
468 intended to replace the macro SCM_COERCE_SUBSTR. Such a macro
469 will be necessary, even after copy-on-write strings will be added
470 to guile, but the current naming is inappropriate.
472 * strorder.c (scm_string_equal_p, scm_string_ci_equal_p,
473 scm_string_less_p, scm_string_ci_less_p): Don't accept symbols as
474 input parameters. Further, the functions that test for equality
475 are rewritten to compare from back to front, the others are also a
476 little bit more polished.
478 2000-10-25 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
480 This change merges the GOOPS code into Guile. However, GOOPS
481 is still not initialized until someone asks for the module.
482 We need to optimize GOOPS initialization time before initializing
483 it together with the rest of libguile. We also need to add the
484 C API + primitive methods. Then we can start using it to

984 the string. This might not be `\0' and might even not be
987 2000-09-12 Dirk Herrmann <D.Herrmann@tu-bs.de>
989 * symbols.c (scm_symbol_p): Eliminate redundant SCM_IMP test.
991 2000-09-12 Dirk Herrmann <D.Herrmann@tu-bs.de>
993 This patch unifies the formerly distinct ssymbol and msymbol types
994 to a common symbol type scm_tc7_symbol. The representation of the
995 new symbol type uses a double cell with the following layout:
996 <type/length, chars, raw_hash, prop-pair>, where the car of
997 prop-pair holds the symbol's function property and the cdr of
998 prop-pair holds the symbol's other properties. In the long run,
999 these properties will be removed. Then, the generic property
1000 functions will be uses.
1002 * eval.c (SCM_CEVAL), objects.c (scm_class_of), print.c
1003 (scm_iprin1), tag.c (scm_tag): Use scm_tc7_symbol instead of
1004 scm_tc7_ssymbol, scm_tc7_msymbol or scm_tcs_symbols.
1006 * gc.c (scm_gc_mark): Mark the symbols property pair.
1008 (scm_gc_sweep): There are no symbol slots any more.
1010 * hash.c (scm_hasher): Instead of re-calculating the hash value
1011 of a symbol, use the raw_hash value stored in the symbol itself.
1013 * properties.h: Fix typo.
1015 * strings.[ch] (scm_makstr, scm_makfromstr): The slot parameter
1016 is not used any more.
1018 * symbols.[ch] (scm_strhash): Deprecated, replaced by a macro.
1020 (scm_intern_obarray_soft): Made softness parameter unsigned.
1022 (scm_string_hash): New function with the same functionality as
1023 scm_strhash had before, except that the hash value is not adjusted
1024 to a hash table size. Instead, the 'raw' hash value is returned.
1026 * symbols.c (duplicate_string): New static convenience function.
1028 (scm_sym2vcell, scm_sym2ovcell_soft, scm_intern_obarray_soft):
1029 Renamed local variable from scm_hash to hash.
1031 (scm_intern_obarray_soft): Don't check for a negative softness
1032 any more. When generating symbol cells, use the new layout and
1033 store the raw hash value in the symbol's cell.
1035 (scm_symbol_to_string): Removed unnecessary cast.
1037 (scm_intern_symbol, scm_unintern_symbol): Use scm_string_hash to
1038 determine the hash values.
1040 (msymbolize): Removed.
1042 (scm_symbol_fref, scm_symbol_pref, scm_symbol_fset_x,
1043 scm_symbol_pset_x, scm_symbol_hash): No need to distinguish
1044 between different symbol types any more.
1046 (scm_symbol_hash): Comment fixed.
1048 * symbols.h: Comment about the distinction between ssymbols and
1051 (SCM_SYMBOLP, SCM_ROSTRINGP): No need to distinguish between
1052 different symbol types any more.
1054 (SCM_PROP_SLOTS, SCM_SET_PROP_SLOTS): Added.
1056 (SCM_SYMBOL_FUNC, SCM_SET_SYMBOL_FUNC, SCM_SYMBOL_PROPS,
1057 SCM_SET_SYMBOL_PROPS, SCM_SYMBOL_HASH, SCM_SET_SYMBOL_HASH): Use
1058 the new symbol cell layout.
1060 * tags.h (scm_tc7_ssymbol, scm_tc7_msymbol, scm_tcs_symbols):
1063 2000-09-12 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
1065 * symbols.h (scm_gentemp): Declared.
1067 * symbols.c (scm_gensym): Reimplemented. Now only takes one
1068 optional argument which should be a *string*.
1069 (scm_gentemp): Reimplemented and moved from boot-9.scm.
1071 2000-09-10 Keisuke Nishida <kxn30@po.cwru.edu>

1076 (scm_eval_closure_tag): New variable.
1077 (scm_eval_closure_lookup): Renamed from eval_closure.
1078 This function now takes a smob instead of a compiled closure.
1079 (scm_standard_eval_closure): Create a smob instead of a compiled

1082 * modules.h (SCM_EVAL_CLOSURE_P): New macro.
1083 (scm_eval_closure_tag, scm_eval_closure_lookup): Declare.
1084 * symbols.c: Include "libguile/smob.h".
1085 (scm_sym2vcell): Call scm_eval_closure_lookup directly if THUNK
1088 2000-09-10 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
1090 * Makefile.am (.x.doc): Bugfix: Added $(srcdir) to path in order
1091 to allow for builds in separate tree.
1093 * symbols.c (scm_gensym): Bugfixed my previous bugfix. (Thanks to
1096 2000-09-10 Keisuke Nishida <kxn30@po.cwru.edu>
1098 * eval.c (SCM_APPLY): Fixed bugs in the applicable-smob calls.

1115 * symbols.c (scm_gensym): Check that argument is a symbol, not a
1116 string. (Thanks to Ralf Mattes.)
1118 2000-09-05 Marius Vollmer <mvo@zagadka.ping.de>
1120 * init.c: Include "libguile/properties.h".
1122 * gh_data.c (gh_scm2char): Validate that argument is a character.
1124 2000-08-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
1126 * environments.h (SCM_IMPORT_ENVIRONMENT_P,
1127 SCM_EXPORT_ENVIRONMENT_P): Before fetching the environment
1128 functions, make sure that we really got an environment.
1130 2000-09-03 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
1132 * validate.h (SCM_VALIDATE_NUMBER_DEF_COPY): New macro.
1134 2000-09-03 Marius Vollmer <mvo@zagadka.ping.de>
1136 * Makefile.am (.x.doc): Pretend to create .doc files from .x files
1137 and give explicit dependencies for .x files that depend on
1138 generated files. This allows parallel builds. Thanks to Matthias
1141 2000-08-27 Marius Vollmer <mvo@zagadka.ping.de>
1143 * Makefile.am: Added gc_os_dep.c, properties.c, properties.x,
1144 properties.h and properties.doc in the suitable places.

1153 * root.h (scm_properties_whash): New `sys_protect', used in
1156 * throw.c (scm_ithrow): Perform catch-all handling here when no
1157 suitable handler has been found. That way, we don't have to rely
1158 on the user establishing a catch-all, which might be difficult for
1159 him if he is using scm_init_guile instead of scm_boot_guile.
1161 2000-09-03 Neil Jerram <neil@ossau.uklinux.net>

1173 (scm_symbol_to_string): Escape double quotes correctly within
1176 * struct.c (scm_make_struct, scm_make_vtable_vtable): Docstring
1177 fixes: `@dots' changed to `@dots{}'.
1179 * strop.c (scm_substring_move_x): Docstring: add @deffnx lines for
1180 substring-move-left! and substring-move-right!.

1204 2000-09-03 Michael Livshin <mlivshin@bigfoot.com>
1206 the following changes let Guile get rid of the `allocated' cell
1209 * smob.c (scm_smob_prehistory): don't init the "allocated" smob
1212 * tags.h (scm_tc16_allocated): removed.
1214 * gc.h: removed now-obsolete comments about the `allocated' cell
1216 (SCM_NEWCELL): don't change cell type to `allocated'.
1217 (SCM_NEWCELL2): ditto.
1219 * gc.c (scm_mark_locations): mark freecells too, and don't worry
1220 about any possible false positives.
1221 (scm_debug_newcell): don't change cell type to `allocated'.
1222 (scm_debug_newcell2): ditto.
1223 (scm_gc_for_newcell): ditto.
1224 (scm_gc_mark): remove the tc16_allocated case.
1226 2000-08-26 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
1228 * gdbint.c (gdb_print): Removed superfluous macro definition.
1230 * objects.c (scm_init_objects), print.c (scm_init_print), struct.c
1231 (scm_init_struct): First arg to scm_make_vtable_vtable should be a
1232 string, not a symbol. (`make-vtable-vtable' needs to append this
1233 string to another string and then pass it through
1234 `make-struct-layout'.)
1236 * stacks.c (scm_init_stacks): Pass a string, not a layout object,
1237 to scm_make_vtable_vtable. (Thanks to Dale P. Smith.)
1239 * struct.c (scm_make_struct_layout): Removed reference to
1240 "read-only string" in comment; Check that argument is a string.
1241 (scm_make_vtable_vtable): Check that argument is a string.
1243 * environments.c (scm_init_environments): All internal includes in
1244 libguile must use the prefix "libguile/" in path names since inly
1245 the top-level source directory is on the include list. (That, in
1246 turn, is because we want to distinguish between system header
1247 files and hedares files internal to libguile.)
1249 * strings.c (scm_make_shared_substring, scm_read_only_string_p):
1251 (scm_string_length, scm_string_ref, scm_substring,
1252 scm_string_append): Don't accept symbols as arguments (R5RS).
1254 2000-08-25 Neil Jerram <neil@ossau.uklinux.net>
1256 * ports.c (scm_set_port_column_x): Fix docstring so that it
1257 mentions set-port-line! rather than set-port-column! twice.
1259 * guardians.c (scm_make_guardian): Remove spurious . from doc string.

1270 goes to Jost Boekemeier.
1272 2000-08-25 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
1274 * procprop.c: #include "libguile/smob.h"; handle applicable smobs.

1280 (scm_set_smob_apply): New function.
1281 (scm_smob_apply_0, scm_smob_apply_1, scm_smob_apply_2,
1282 scm_smob_apply_3): New functions.
1283 * eval.c (SCM_CEVAL, SCM_APPLY): Added dispatch for applicable smobs.
1284 * procs.c (scm_procedure_p): Check applicable smobs.
1286 2000-08-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1288 * Makefile.am (BUILT_SOURCES): Experimentally added scmconfig.h
1289 also here. (This is supposed to make sure that scmconfig.h is
1290 built before all sources in order to prevent that everything has
1291 to be rebuilt again. Hope it works---I'm just guessing. :)
1293 * fluids.c (scm_fluid_set_x): Return SCM_UNSPECIFIED.
1295 2000-08-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1297 * gc.c (scm_gc_mark): Don't use GUILE_DEBUG flag to compile in
1298 extra tests. (GUILE_DEBUG is only supposed to make extra
1299 debugging functions available.)
1301 2000-08-21 Michael Livshin <mlivshin@bigfoot.com>
1303 * gc.h (SCM_GC_CARD_N_CELLS): change to be a nice non-confusing
1306 2000-08-19 Michael Livshin <mlivshin@bigfoot.com>
1308 * gc.c (scm_gc_sweep): added a `continue' statement that have
1309 fallen through the cracks in the merge. thanks to Shuji Narazaki!
1311 * gc.h: removed some stuff that broke compilation for people and
1312 wasn't actually needed anyway.
1314 2000-08-18 Neil Jerram <neil@ossau.uklinux.net>
1316 * filesys.c (scm_fcntl): Docstring fix - missing newlines inserted.
1318 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_sethost,
1319 scm_setnet, setproto, setserv): Argument names changed to match
1322 * feature.c (scm_program_arguments): New docstring.
1324 * simpos.c (scm_getenv): Reflow docstring.
1326 * eq.c (scm_eq_p, scm_eqv_p, scm_equal_p): Add texinfo markup to
1329 * chars.c (scm_char*): Docstring fixes - texinfo markup.
1331 2000-08-18 Neil Jerram <neil@ossau.uklinux.net>
1333 * boolean.c (scm_not, scm_boolean_p): Docstring fixes - add
1334 texinfo markup and remove trailing newlines.
1336 2000-08-17 Michael Livshin <mlivshin@bigfoot.com>
1338 this changes the Guile GC to use cards (aka "chunklets").
1339 (most of the ideas and some of the code are by Greg Harvey, though
1340 the code is probably unrecognizable now. the original chunklet
1341 proposal, way back, is by Dale Jordan).
1343 * tags.h: (SCM_GCTYPE16, SCM_GCCDR, SCM_GC[8]MARKP,
1344 SCM_SETGC[8]MARK, SCM_CLRGC[8]MARK): moved from here into gc.h.
1345 some (most) of these are probably going to be deprecated.
1347 * gc.h (SCM_MARKEDP): simplified, there are no different mark bit
1349 (SCM_GC_CARD_*, SCM_C_BVEC_*): lots of new macros to deal with
1350 cards and bvecs (bit-vectors).
1352 * gc.c: (scm_default_init_heap_size_*): defined to take cards into
1353 account, but keeping more or less the same values as previously.
1354 added some simple helper macros.
1355 (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK): defined to take cards
1357 (BVEC_*, scm_mark_space_t, current_mark_space, mark_space_ptr,
1358 current_mark_space_offset, mark_space_head, get_bvec,
1359 clear_mark_space): new functions and supporting variables, types
1360 and macros that implement mark space management.
1361 (scm_igc): clear the mark space (all of it) before beginning the
1363 (scm_gc_mark): changed the tests for rogue cells, much simplified
1364 throughout (no different mark bit locations to worry about now).
1365 (scm_mark_locations): don't consider card header cells.
1367 (scm_gc_sweep): simplified.
1368 (init_heap_seg): changed to take cards into account.
1370 2000-08-16 Michael Livshin <mlivshin@bigfoot.com>
1372 * stime.c (scm_c_get_internal_run_time): new function, same as
1373 scm_get_internal_run_time but returns a long. it's used by the GC
1374 for timekeeping, since with scm_get_internal_run_time there is a
1375 (extremely theoretical) possibility of consing.
1376 (scm_get_internal_run_time): redefined in terms of
1377 scm_c_get_internal_run_time.
1379 * stime.h: added prototype for scm_c_get_internal_run_time.
1381 * gc.c (scm_gc_stats): add more obscure stats, such as: mark time,
1382 sweep time, total marked cells, total swept cells, and number of
1383 times GC was invoked.
1384 (gc_start_stats): renamed from scm_gc_start, made static, taught
1385 to init the new stats.
1386 (gc_end_stats): renamed from scm_gc_end, made static, taught to
1387 calculate the new stats.
1388 (scm_igc): don't call gc_start_stats unless we are sure that we
1389 are indeed going to collect. also, added some timekeeping between
1390 the mark and sweep phases.
1391 (scm_gc_sweep): count number of cells we sweep as we go.
1393 * gc.h: removed prototypes for scm_gc_{start,end}.
1395 2000-08-13 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
1397 * alist.c (scm_assq, scm_assv, scm_assoc): Report argument type

1426 * list.c (scm_list_tail): Add @deffnx line to docstring for
1429 * keywords.c: Docstring improvements in conjunction with new
1430 reference manual doc on keywords.
1432 * error.c (scm_error_scm): Fix texinfo syntax error in
1433 docstring. (@code(~S) should be @code{~S}.)
1435 * dynl.c: Remove surplus newlines from end of docstrings.
1437 2000-08-11 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
1439 * eval.c (scm_eval): Backward incompatible change: Now takes an
1440 environment specifier as second arg. `eval' hereby becomes R5RS
1442 (scm_i_eval_x, scm_i_eval): New functions (replace
1444 (scm_eval2, scm_eval_3): Deprecated.

1474 to new scm_i_eval_x; Don't call it if module system hasn't booted.
1475 (scm_read_and_eval_x): Deprecated.
1476 #include "modules.h".

1488 The following changes are intended to ensure that struct instances
1489 are freed before their vtables. It's optimized for the most
1490 common case, which is freeing of struct instances.

1533 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
1534 scm_assoc_remove_x): Use scm_delq1_x instead of scm_delq_x, since
1535 using the latter is pointless.
1537 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
1539 * gc.c (scm_gc_sweep): Renamed local variable from 'free' to
1540 'free_struct_data' to avoid confusion with stdlib's 'free'.
1542 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
1544 * vectors.c (scm_make_vector): Fix the initialization order of
1545 the vector such that the type cell is initialized last.
1547 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
1549 * struct.[ch] (scm_struct_init): Made static. Fixed not to rely
1550 on the struct cell to be fully initialized.
1552 * struct.c (scm_make_struct, scm_make_vtable_vtable): Fix the
1553 initialization order of the struct such that the type cell is
1556 2000-07-25 Marius Vollmer <mvo@zagadka.ping.de>
1558 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
1559 scm_assoc_remove_x): Remove only the first cell with a matching
1562 2000-07-24 Marius Vollmer <mvo@zagadka.ping.de>
1564 * stime.c (scm_strftime): Recognize a return value of zero from
1565 strftime as buffer overflow and take care to detect a valid zero
1566 length result regardless. Thanks to David Barts!
1568 2000-07-23 Marius Vollmer <mvo@zagadka.ping.de>
1570 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
1571 scm_assoc_remove_x): Remove all cells whose key is eq, eqv, or
1572 equal (respectively) to the argument key, not all cells that are
1573 eq, eqv, or equal to the first cell with the argument key. Thanks
1576 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
1578 * gc.h (SCM_FREE_CELL_CDR, SCM_SET_FREE_CELL_CDR), hooks.c
1579 (make_hook), modules.c (OBARRAY, USES, BINDER): Pack and unpack
1580 SCM values appropriately.
1582 * modules.c (scm_standard_eval_closure): Don't pass an inum to
1583 scm_makcclo, but rather a long value.
1585 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
1587 read.c (scm_lreadrecparen), srcprop.c (scm_set_source_property_x):
1588 SCM_SETCDR and SCM_WHASHSET macros don't deliver a return value.
1589 Thanks to Han-Wen Nienhuys for the bug report.
1591 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
1593 * root.[ch] (scm_call_catching_errors): Deprecated.
1595 * root.c (scm_init_root): Initialize the root smob type using the
1596 standard initialization functions.
1598 2000-07-17 Marius Vollmer <mvo@zagadka.ping.de>
1600 * eval.c (unmemocopy): Don't rely on V being a list of at least
1601 one element. Thanks to Bill Schottstaedt!
1603 2000-07-15 Michael Livshin <mlivshin@bigfoot.com>
1605 * gc.c (scm_done_free): new.
1606 expanded comments about scm_done_malloc.
1608 * gc.h: added prototype for scm_done_free
1610 2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
1612 * gc.h (scm_take_stdin): Removed.
1614 * gc.h (SCM_VALIDATE_CELL): Delegate cell checks to function
1615 scm_assert_cell_valid to allow extensions to the checking
1616 functionality without need to recompile everything.
1618 * gc.[ch] (scm_assert_cell_valid, scm_set_debug_cell_accesses_x):
1619 Added as conditionally compiled functions for the case that
1620 SCM_DEBUG_CELL_ACCESSES is enabled.
1622 * gc.c (debug_cells_p): Added to indicate whether compile-time
1623 included cell access debugging is run-time enabled.
1625 * gc.[ch] (scm_gc_running_p): Added to indicate that scm_igc is
1626 being executed. Intended to be used instead of scm_gc_heap_lock
1629 * error.c (scm_error), gdbint.c (SCM_GC_P): Use scm_gc_running_p
1630 instead of scm_gc_heap_lock.
1632 * gc.c (scm_igc): Set scm_gc_running_p to true while running.
1634 * gc.c (scm_mark_locations): Don't mark free cells.
1636 * weaks.c (scm_scan_weak_vectors): Use SCM_FREE_CELL_P instead of
1639 2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
1641 * gc.c (scm_mark_locations): Minimized some variable scopes and
1642 simplified the code a bit.
1644 2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1646 * gc.h (SCM_SET_FREE_CELL_TYPE, SCM_SET_FREE_CELL_CDR,
1647 SCM_FREE_CELL_P, SCM_FREE_CELL_CDR): Added since free cells
1648 should not be accessed via SCM_C[AD]R. Further, using dedicated
1649 macros to access free cells allows all other cell accessing macros
1650 to treat acesses to free cells as errors, thus enabling better
1651 error checks for cell accesses. SCM_FREE_CELL_P is supposed to
1652 replace SCM_FREEP some time.
1654 * gc.h (SCM_NEWCELL, SCM_NEWCELL2), gc.c (map_free_list,
1655 free_list_length, scm_check_freelist, scm_debug_newcell,
1656 scm_debug_newcell2, freelist_length, scm_gc_for_newcell,
1657 scm_gc_mark, scm_gc_sweep, init_heap_seg): Only use the dedicated
1658 cell accessors when accessing free cells.
1660 2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1662 * gc.h (SCM_CELL_WORD, SCM_CELL_OBJECT): Treat the referenced
1663 object as const in order to make the compiler warn about code like
1664 SCM_CELL_WORD (x, n) = y. Instead, SCM_SET_CELL_WORD (x, n, y)
1667 (SCM_CELL_WORD_LOC, SCM_CARLOC, SCM_CDRLOC): Return the address
1668 as an address to a non-const object, since these macros are used
1669 to allow direct write access to objects.
1671 2000-07-07 Dirk Herrmann <D.Herrmann@tu-bs.de>
1673 * hashtab.c (scm_hash_fn_create_handle_x): Signal an error if the
1674 given hash table has no slots.
1676 2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
1678 * gc.c (policy_on_error): Added in order to allow alloc_some_heap
1679 to react to malloc failures in a context dependent way.
1681 (scm_check_freelist): No need to flush streams before abort().
1683 (scm_gc_for_newcell): Try to allocate new memory in three phases:
1684 grow heap if preferred, if still no memory available collect
1685 garbage, if still no memory available grow heap.
1687 (heap_segment_table_size): Added to always reflect the actual
1688 size of the heap segment table, because scm_n_heap_segs may differ
1689 from the heap segment table size.
1691 (alloc_some_heap): In case of malloc failure, react according to
1692 the new policy_on_error parameter (either return to caller or
1693 abort immediately). Further, keep heap_segment_table_size up to
1696 (scm_init_storage): Initialize heap_segment_table_size.
1698 2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
1700 * gh.h: Don't include <stdio.h>. Thanks to Han-Wen Nienhuys for
1703 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
1705 * __scm.h (SCM_OUTOFRANGE, SCM_NALLOC, SCM_HUP_SIGNAL,
1706 SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL, SCM_SEGV_SIGNAL,
1707 SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL, SCM_SIG_ORD,
1708 SCM_ORD_SIG, SCM_NUM_SIGS): Re-introduce these as deprecated
1711 * error.c (scm_wta): Re-introduce dispatching for SCM_OUTOFRANGE
1712 and SCM_NALLOC, but as a deprecated feature.
1714 2000-06-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1716 * debug.c: Added #include fluids.h.
1718 * numbers.c (scm_gr_p, scm_leq_p, scm_geq_p): Turned into
1719 primitive generics. (Thanks to Nicolas Neuss.)
1721 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
1723 * gc.c (alloc_some_heap): Use scm_memory_error to indicate a
1724 failed attempt to get additional memory from the system.
1726 (scm_gc_for_newcell): Changed the control structure to make the
1727 behaviour explicit for the case that gc is not able to free any
1730 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
1732 * __scm.h (SCM_OUTOFRANGE): Removed.
1734 * error.c (scm_wta): Removed sick dispatch code for range
1735 errors. (More sick dispatches still to be removed.)
1737 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
1738 scm_hash_fn_remove_x): Eliminate redundant test for if unsigned
1739 value is non-negative. Use scm_out_of_range to signal range
1742 * hooks.c (make_hook), unif.c (scm_aind): Use scm_out_of_range to
1743 signal range errors.
1745 * list.c (scm_list_ref, scm_list_set_x, scm_list_cdr_set_x): Fix
1746 error reporting (now uses original input parameter to report wrong
1747 type argument errors). Use SCM_OUT_OF_RANGE to report range
1748 errors and SCM_WRONG_TYPE_ARG to report type errors.
1750 * strings.c (scm_substring): Make range checks for negative
1751 values explicit (former behaviour relied on an implicit
1752 conversion from signed to unsigned). Don't use SCM_ASSERT for
1755 * unif.c (scm_aind, scm_transpose_array, scm_bit_set_star_x,
1756 scm_bit_count_star): Use scm_out_of_range to signal range
1759 * unif.c (scm_transpose_array, scm_bit_position), vectors.c
1760 (scm_vector_ref, scm_vector_set_x, scm_vector_move_left_x,
1761 scm_vector_move_right_x): Use SCM_ASSERT_RANGE to check ranges.
1763 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
1765 * validate.h (SCM_VALIDATE_INUM_MIN_COPY,
1766 SCM_VALIDATE_INUM_MIN_DEF_COPY, SCM_VALIDATE_INUM_RANGE_COPY):
1767 Perform all range checks based on the input value. The former way
1768 of using the value that is assigned to the target variable fails
1769 if the assignment to the target variable itself can change the
1770 value because of type conversion.
1772 (SCM_ASSERT_RANGE): Use scm_out_of_range to signal range errors.
1774 2000-06-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1776 * gc.c (scm_gc_for_newcell): Behave gracefully also if scm_igc
1777 doesn't yield any new cells. In theory this could happen if all
1778 cells allocated with NEWCELL are either in use or conservatively
1779 marked and all cluster spine cells are conservatively marked.
1782 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1784 * __scm.h (SCM_NALLOC): Removed.
1786 * error.c (scm_wta): Removed sick dispatch code for memory
1787 errors. (More sick dispatches still to be removed.)
1789 * numbers.c (scm_mkbig, scm_adjbig), ports.c (scm_make_port_type),
1790 random.c (scm_i_copy_rstate, scm_c_make_rstate), smob.c
1791 (scm_make_smob_type), srcprop.c (scm_make_srcprops), vectors.c
1792 (scm_vector_set_length_x): Now using scm_memory_error to signal
1795 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1797 * __scm.h: Removed some commented code and fixed some comments.
1799 (SCM_HUP_SIGNAL, SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL,
1800 SCM_SEGV_SIGNAL, SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL,
1801 SCM_SIG_ORD, SCM_ORD_SIG, SCM_NUM_SIGS): Removed.
1803 * async.c: Removed some commented code.
1805 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1807 * gc.c (scm_gc_mark, scm_gc_sweep, scm_must_malloc,
1808 scm_must_realloc, scm_must_free, alloc_some_heap): Use the
1809 appropriate error signalling function.
1811 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1813 * root.h (scm_first_type): Removed.
1815 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1817 * gc.c (MIN_GC_YIELD): Removed.
1819 2000-06-28 Michael Livshin <mlivshin@bigfoot.com>
1821 * gc.c (scm_gc_for_newcell): don't try to do GC if it's blocked,
1824 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1826 * async.c (scm_gc_async, scm_gc_vcell, scm_sys_gc_async_thunk):
1829 (scm_init_async): Moved initialization for scm_gc_async and
1830 scm_gc_vcell to gc.c. Moved initialization of scm_asyncs here
1833 * async.h (scm_gc_async): Not globally visible any more.
1835 * gc.c (scm_gc_stats): Made callable even from within regions
1836 where gc is blocked.
1838 (scm_gc_end): Eliminate the hardcoding of the marking of the
1839 scm_gc_async from the gc core.
1841 (scm_init_storage): Don't initialize the scm_asyncs list here.
1842 This is now done in asyncs.c.
1844 (scm_gc_vcell): Moved here from async.c.
1846 (gc_async): Renamed from scm_gc_async, moved here from async.c
1849 (gc_async_thunk): Renamed from scm_sys_gc_async_thunk and moved
1852 (mark_gc_async): New hook function for scm_after_gc_c_hook.
1854 (scm_init_gc): Added initialization of scm_gc_vcell and
1855 gc_async. Further, add mark_gc_async to scm_after_gc_c_hook.
1857 * init.c (scm_boot_guile_1): scm_init_gc requires asyncs to be
1860 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1862 * gc.c (scm_igc): Removed commented code that once was intended
1863 to unprotect struct types with no instances.
1865 * root.h (scm_type_obj_list): Removed.
1867 2000-06-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
1869 * async.c (scm_init_async): Switch to standard way of smob
1872 2000-06-21 Michael Livshin <mlivshin@bigfoot.com>
1874 * guile-doc-snarf.in: use cut instead of sed, that's much much
1875 faster. also, don't call basename more than needed. and, to gain
1876 a couple of microseconds more, don't call cat needlessly. (thanks
1879 2000-06-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
1881 * guile-snarf.awk.in, guile-snarf.in, snarf.h: Rename SCM__I to
1882 SCM_SNARF_INIT_START, SCM__D to SCM_SNARF_DOC_START, SCM__S to
1883 SCM_SNARF_DOCSTRING_START and SCM__E to SCM_SNARF_DOCSTRING_END.
1885 2000-06-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1887 * eval.c, eval.h (scm_top_level_lookup_closure_var): Added.
1888 #include "libguile/fluids.h".
1890 * eval.h (SCM_TOP_LEVEL_LOOKUP_CLOSURE): New macro which replaces
1891 SCM_CDR (scm_top_level_lookup_closure_var) everywhere.
1893 * root.h (scm_top_level_lookup_closure_var,
1894 scm_system_transformer): Removed. (It's no sense in having the
1895 *variable* be a "fluid".)
1897 * root.c (mark_root): Removed marking of
1898 s->top_level_lookup_closure_var and s->system_transformer.
1900 * modules.c (scm_selected_module): the_module is now a fluid.
1902 2000-06-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1904 * gc.h, tags.h: Be kind to compilers which must see hash signs in
1905 column 0. (Thanks to Ian Grant.)
1907 * numbers.h: Put #ifdef HAVE_LONG_LONGS around declarations using
1908 the long_long type. (Thanks to Bernard Urban.)
1910 2000-06-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1912 * gc.c, gc.h (scm_default_init_heap_size_1,
1913 scm_default_min_yield_1, scm_default_init_heap_size_2,
1914 scm_default_min_yield_2, scm_default_max_segment_size): New global
1915 variables. Can be customized by the application before booting
1916 Guile. (We might want to be able to control these parameters
1917 dynamically through the "options interface" in the future, but
1918 note that that is additional functionality. Here we're giving
1919 default values which the environment variables can override.)
1921 * list.c (scm_cons_star): Updated comment.
1923 * smob.h: Changed comments for scm_make_smob_type and
1924 scm_make_smob_type_mfpe, warning that the latter might be
1925 deprecated in a future release.
1927 2000-06-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
1929 * list.[ch] (scm_cons_star/cons*): Renamed from
1930 scm_list_star/list*.
1932 * list.[ch] (scm_list_star/list*): Provided as a deprecated alias
1933 for scm_cons_star/cons*.
1935 * gc.c (scm_protect_object): Updated comment.
1937 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX): Removed.
1939 * tags.h (SCM_UNPACK_CAR, SCM_NDOUBLE_CELLP): Removed.
1941 2000-06-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1943 * init.c, init.h (scm_initialized_p): Renamed from `initialized'
1946 * gdbint.c (gdb_print): Print warning instead of calling scm_write
1947 if Guile isn't yet initialized.
1949 * print.c (scm_current_pstate, scm_make_print_state): Simplified
1950 tests, using the assumption that Guile has been initialized.
1952 Sun Jun 18 14:45:21 2000 Greg J. Badros <gjb@cs.washington.edu>
1954 * print.c (s_scm_current_pstate): Do not segfault when the
1955 print_state_pool is unitialized in `current-pstate', and better
1956 verify its state before altering it in scm_make_print_state().
1958 2000-06-18 Michael Livshin <mlivshin@bigfoot.com>
1960 * scmsigs.c (s_scm_sigaction): guard the SIGIOT case with an
1961 #ifdef -- it's missing on at least one platform. (thanks to
1964 2000-06-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
1966 * list.c (list*): Added documentation from common-list.scm.
1968 2000-06-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
1970 * gc.c (scm_unprotect_object): The reference count is guaranteed
1971 to be a positive number.
1973 2000-06-15 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1975 * eval.c: Updated comment above scm_map.
1977 2000-06-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1979 * gc.c (scm_protect_object): Avoid looking up the object handle
1981 (scm_unprotect_object): Abort if scm_unprotect_object is called on
1982 an unprotected object.
1984 2000-06-14 Michael Livshin <mlivshin@bigfoot.com>
1986 * gc.c (scm_unprotect_object): fix a nasty typo bug (thanks to
1989 2000-06-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1991 * socket.c (scm_getsockopt): Changed type for `optlen' from int to
1993 (scm_accept, scm_getsockname, scm_getpeername, scm_recvfrom):
1994 Ditto for `tmp_size'.
1995 (scm_addr_buffer_size): Changed type from int to size_t.
1997 * random.c: #include <string.h>. (Needed by memcpy.)
1999 * guile-snarf.awk.in: Replace the dot_doc_file arg with "-",
2000 indicating stdin, instead of "" and don't reset ARGC. This is a
2001 workaround for `nawk' in AIX 4.3 on RS6000 but, as far as I know,
2002 it is correct, and perhaps even better.
2004 2000-06-14 Gary Houston <ghouston@arglist.com>
2006 * scmsigs.c (scm_init_scmsigs): if HAVE_SIGINTERRUPT is not
2007 defined, add SA_RESTART to the sigaction flags correctly
2008 (thanks to Dale P. Smith).
2010 2000-06-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2012 * strings.c: #include <string.h>. (Thanks to Bill Schottstaedt.)
2014 * net_db.c (scm_resolv_error): Only use macro NETDB_INTERNAL if
2015 defined. It isn't on sgi irix 5.3. (Thanks to Bill Schottstaedt.)
2017 * Makefile.am (.c.doc): Pipe output (the .x contents) to /dev/null.
2019 2000-06-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2021 * fports.c (scm_setvbuf): Use `free' instead of `scm_must_free'
2022 since read and write buffers are allocated by `malloc'.
2024 * Makefile.am: Removed old test code.
2026 * gh_test_c.c, gh_test_repl.c: Removed.
2028 2000-06-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2030 * iselect.c (SCM_NLONGBITS): Add workaround for the Sun 4.2
2033 * inet_aton.c (inet_aton): Cast init value for `cp'.
2035 * ramap.c (s_scm_array_fill_x): Cast `ve' properly in case
2038 * symbols.c (scm_intern_obarray_soft,
2039 scm_sysintern0_no_module_lookup): Cast `name' to unsigned char ptr
2040 in calls to scm_strhash.
2042 * strports.c (st_resize_port): Substituted SCM_UCHARS for
2044 (st_write): Cast argument to strncpy to char ptr.
2045 (scm_mkstrport): Substituted SCM_ROUCHARS for SCM_ROCHARS.
2046 (scm_strport_to_string): Cast argument to scm_makfromstr to char
2049 * ports.c (scm_ungetc): Cast value to unsigned char ptr before
2050 storing in putback_buf.
2051 (scm_unread_string): Substituted SCM_ROCHARS for SCM_ROUCHARS.
2053 * ioext.c (s_scm_read_line): Cast result of call to
2054 scm_do_read_line to unsigned char ptr.
2056 * gdbint.c (SEND_STRING): Cast argument to char pointer.
2058 * fports.c (fport_flush): Declare `ptr' as unsigned char (was
2061 * Makefile.am (DOT_DOC_FILES): List doc-files explicitly. (We
2062 shouldn't use Make rules which aren't supported by most Make
2064 (OMIT_DEPENDENCIES): Defined to "libguile.h ltdl.h". (We don't
2065 want these dependencies recorded, since they would get bogus
2066 relative paths; libguile.h is only used in gh.h and guile.c.)
2067 (EXTRA_DOT_X_FILES, EXTRA_DOT_DOC_FILES): New variables.
2068 (guile-procedures.txt): Depend on EXTRA_DOT_DOC_FILES.
2069 (modinclude_HEADERS): Removed kw.h.
2071 * guile-snarf.in: Change regexp "^SCM__I" --> "^ *SCM__I".
2072 (The preprocessor might insert spaces before the identifier.)
2074 * snarf.h (SCM_SNARF_HERE, SCM_SNARF_INIT, SCM_SNARF_DOCS):
2075 Renamed from SCM_HERE, SCM_INIT, SCM_DOCS.
2077 * smob.h (scm_smobfuns): Removed deprecated type.
2079 * smob.c, smob.h (scm_newsmob): Removed deprecated function.
2080 (Replaced by `scm_make_smob_type'.)
2082 * keywords.c (scm_tc16_kw): Removed deprecated type.
2083 (Replaced by scm_tc16_keyword.)
2085 * kw.h: Removed deprecated header file.
2087 * evalext.c (serial-map): Removed deprected alias for scm_map.
2088 (Has been replaced by `map-in-order'.)
2090 * ramap.c (serial-array-copy!, serial-array-map!): Removed
2091 depracted aliases. (Replaced by `array-copy-in-order!' and
2092 `array-map-in-order'.)
2094 2000-06-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2096 * gc.h (SCM_VALIDATE_CELL): Rewritten.
2097 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
2098 SCM_SET_CELL_OBJECT): Use new version of SCM_VALIDATE_CELL.
2099 (Thanks to Han-Wen Nienhuys.)
2101 2000-06-10 Michael Livshin <mlivshin@bigfoot.com>
2103 * guile-doc-snarf.in: don't pipe the CPP output right into sed --
2104 write it to the temp file first and check the CPP return code.
2105 (I introduced this bug earlier, and this probably caused people
2106 with non-GNU C preprocessors to get empty *.x files and not to
2107 have the build fail right away...).
2109 * scmsigs.c (s_scm_sigaction): guard the SIGSYS case with an ifdef
2110 -- at least my libc5-based Linux system doesn't define SIGSYS.
2112 2000-06-08 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2114 * snarf.h, guile-snarf.awk.in, guile-snarf.in: Replaced snarf
2115 markers with identifiers (SCM__I, SCM__D, SCM__S, SCM__E).
2116 (Thanks to Bernard Urban.)
2118 2000-06-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2120 * modules.c (scm_system_module_env_p): Fixed detection of system
2123 2000-06-06 Marius Vollmer <mvo@zagadka.ping.de>
2125 * scmsigs.c (scm_sigaction): Silently ignore setting handlers for
2126 `program error signals' because they can't currently be handled by
2129 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
2131 * procs.h (SCM_SET_SUBRF): Added.
2133 * procs.c (scm_make_subr_opt): Don't assign to SCM_SUBRF, use
2134 SCM_SET_SUBRF instead. Thanks to Bernard Urban for the bug
2137 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
2139 * gc.h (SCM_CARLOC, SCM_CDRLOC): Don't take the address of a SCM
2142 * sort.c (scm_sorted_p, scm_merge, scm_merge_list_x,
2143 scm_merge_list_step): Don't take the address of SCM_CAR. Use
2144 SCM_CARLOC instead. Thanks to Bernard Urban for the bug report.
2146 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
2148 * boolean.h (SCM_TRUE_P): Removed, as people might use it as a
2149 replacement for !SCM_FALSEP.
2151 * backtrace.c (display_error_body), boolean.h (SCM_BOOLP), gc.c
2152 (scm_unhash_name), gh_data.c (gh_module_lookup), load.c
2153 (scm_primitive_load), print.c (scm_simple_format), procs.c
2154 (scm_procedure_documentation), procs.h (SCM_TOP_LEVEL), ramap.c
2155 (scm_array_fill_int), scmsigs.c (scm_sigaction), stacks.c
2156 (narrow_stack, scm_make_stack, scm_stack_id), symbols.c
2157 (scm_string_to_obarray_symbol), throw.c (scm_catch,
2158 scm_lazy_catch, scm_ithrow), unif.c (scm_make_uve, scm_array_p,
2159 scm_array_set_x, scm_bit_set_star_x, scm_bit_count_star),
2160 validate.h (SCM_VALIDATE_BOOL_COPY, SCM_VALIDATE_PROC): Replace
2161 uses of SCM_TRUE_P (x) with SCM_EQ_P (x, SCM_BOOL_T).
2163 2000-06-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2165 * eval.c (scm_badformalsp): New static function.
2166 (SCM_CEVAL): Check arguments for procedure-with-setter closures.
2167 (Thanks to Keisuke Nishida.)
2169 The major reason for Guile's slow loading speed has been the fact
2170 that a chain of Scheme level procedures has been evaluated for
2171 every top-level symbol lookup during the first pass through the
2174 The following is a kludge which I suggested four years ago, and
2175 which I've repeatedly suggested since. Personally, I've never
2176 been bothered by Guile's slow loading speed, so I thought I would
2177 let someone else do it...
2179 But since the new environments will be included first in
2180 Guile-1.5, I thought it would make people happy to get the kludge
2183 * modules.c: Added #include "libguile/vectors.h";
2184 Added #include "libguile/hashtab.h";
2185 Added #include "libguile/struct.h";
2186 Added #include "libguile/variable.h";
2187 Capture Scheme level `module-make-local-var!' to be used in the
2188 standard eval closure.
2189 (scm_standard_eval_closure): New primitive.
2191 * modules.h (scm_standard_eval_closure): Declare.
2193 * eval.c (scm_lookupcar): Test for !SCM_CONSP (SCM_CAR (env))
2194 instead of SCM_TRUE (scm_procedurep (SCM_CAR (env))).
2196 * symbols.c (scm_sym2vcell): Bypass dispatch in the evaluator for
2197 standard eval closures.
2199 * variable.c: Code layout fixes.
2201 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2203 * Makefile.am: Added LIBS line to libpath which accidentally
2204 disappeared in the change of 2000-06-01.
2205 (Thanks to Dale P. Smith.)
2207 2000-06-03 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2209 * scmsigs.c (scm_segfault): Removed. (Was probably added by
2210 mistake since it is not mentioned in ChangeLog.)
2212 * gc.h (SCM_VALIDATE_CELL): Cast result to (void) in order to
2213 avoid compiler warnings in gcc. (Does this work for other
2216 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2218 * gc.h (SCM_VALIDATE_CELL): Don't "use" the value returned by
2220 (SCM_CARLOC, SCM_CDRLOC): Define directly instead of using
2221 SCM_CELL_OBJECT_0 and SCM_CELL_OBJECT_1. It's not correct to take
2222 the address of these expressions since they use SCM_VALIDATE_CELL.
2223 (Thanks to Bernard Urban.)
2225 * dynl.c: Changed #include <ltdl.h> --> #include
2226 "libltdl/ltdl.h". (Thanks to Bill Schottstaedt.)
2228 2000-06-01 Craig Brozefsky <craig@red-bean.com>
2230 * Makefile.am: libguile_la_LDFLAGS gets -version-info args
2231 from GUILE-VERSION definition of LIBGUILE version. Added to
2232 libpath.h definitions for guileversion and libguileversion which
2233 both get their values from GUILE-VERSION definition.
2235 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
2237 * numbers.h (SCM_BIGP): Don't use SCM_SMOB_PREDICATE in header
2238 file: Code using numbers should not be required to include
2241 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
2243 * coop-threads.c.cygnus, coop-threads.h.cygnus, fsu-pthreads.h,
2244 mit-pthreads.c, mit-pthreads.h: Deleted.
2246 * Makefile.am (EXTRA_DIST), scmsigs.c, threads.[ch]: Drop
2247 references to deleted files and fsu/mit thread support in
2250 2000-05-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
2252 * hooks.c (symbol_name, scm_create_hook): Restored the original
2253 behaviour of scm_create_hook. Changing it was bad as Carl
2254 R. Witty has pointed out.
2256 * gc.c (scm_init_gc): We can still rely on scm_create_hook to
2259 2000-05-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
2261 * gc.c (scm_init_gc): Protect scm_after_gc_hook, since this will
2262 soon not be done by scm_create_hook any longer.
2264 * hooks.c (make_hook, print_hook, scm_create_hook,
2265 scm_make_hook_with_name, scm_make_hook), hooks.h (SCM_HOOK_NAME,
2266 SCM_HOOK_PROCEDURES, SCM_SET_HOOK_PROCEDURES,
2267 scm_make_hook_with_name), init.c (scm_boot_guile_1): Hooks no
2268 longer have names. As an intermediate solution, the name
2269 predicate is emulated via object properties, but use of this
2270 feature is deprecated.
2272 * hooks.h (scm_free_hook): Removed, as it is never defined.
2274 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2276 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_FIXABLE):
2277 Un-deprecated since otherwise user code can't determine whether a
2278 number fits into an inum any longer. The names should be changed
2281 * numbers.c (scm_big2inum): Eliminated use of SCM_UNEGFIXABLE.
2283 * tags.h (SCM_UNPACK_CAR): Deprecated.
2285 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2287 * filesys.h (SCM_OPDIRP), fluids.h (SCM_FLUIDP, SCM_FLUID_NUM),
2288 fports.h (SCM_OPFPORTP, SCM_OPINFPORTP, SCM_OPOUTFPORTP), hooks.h
2289 (SCM_HOOK_ARITY), keywords.h (SCM_KEYWORDP, SCM_KEYWORDSYM),
2290 numbers.h (SCM_NUMP, SCM_BIGSIGN, SCM_BDIGITS, SCM_NUMDIGS):
2291 Replace SCM_UNPACK_CAR appropriately. Don't access cells via
2292 SCM_{SET}?C[AD]R unless they are known to be cons cells.
2294 * gc.c (scm_heap_seg_data_t, scm_mark_locations, scm_cellp,
2295 init_heap_seg): Remove unused struct member variable 'valid'.
2297 2000-05-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
2299 * fports.c (fport_write), ports.c (scm_markstream, scm_port_mode,
2300 scm_print_port_mode), ports.h (SCM_OPPORTP, SCM_OPINPORTP,
2301 SCM_OPOUTPORTP, SCM_INPUT_PORT_P, SCM_OUTPUT_PORT_P, SCM_OPENP),
2302 procs.h (SCM_CLOSCAR), unif.h (SCM_ARRAY_NDIM, SCM_ARRAY_CONTP),
2303 variable.h (SCM_VARIABLEP): Replace SCM_UNPACK_CAR
2306 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
2308 * gc.c (free_list_length), hash.c (scm_hasher), macros.c
2309 (scm_macro_type), objects.c (scm_class_of), options.c
2310 (scm_options), print.c (scm_iprin1), strports.c (st_seek), throw.c
2311 (SCM_LAZY_CATCH_P): Replace SCM_UNPACK_CAR appropriately.
2313 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
2315 * eval.c (scm_macroexp, SCM_CEVAL, scm_force), tags.h: Replace
2316 SCM_UNPACK_CAR with SCM_CELL_TYPE or SCM_CELL_WORD_0.
2318 * eval.c (scm_force): Add documentation.
2320 * eval.c (scm_force, scm_cons_source): Don't access cells via
2321 SCM_{SET}?C[AD]R unless they are known to be cons cells.
2323 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
2325 * strings.h (SCM_NSTRINGP, SCM_NRWSTRINGP), tags.h
2326 (SCM_NDOUBLE_CELLP), vectors.h (SCM_NVECTORP): Deprecated.
2328 * gc.c (scm_igc), gc.h (SCM_PTR_MASK, SCM_PTR_LT): Removed #ifdef
2329 nosve #endif conditionally compiled code.
2331 2000-05-23 Michael Livshin <mlivshin@bigfoot.com>
2333 * gc.c (scm_heap_seg_data_t): fixed comment for the `span' member.
2335 2000-05-22 Michael Livshin <mlivshin@bigfoot.com>
2337 * guile-doc-snarf.in: put the preprocessed file through sed to
2338 trim all lines to 1024 chars. I hope it doesn't break anybody's
2339 sed. we'll see. (note: this is lossy trimming, i.e. the spill
2340 isn't wrapped around but actually chopped off. this seemed to me
2341 safe because the current snarfer doesn't understand multi-line
2342 cookies anyway. in the long term, it would be nice not to depend
2343 on AWK for anything.)
2345 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): reverted
2346 the previous change to this macros, after deciding to torture the
2349 2000-05-21 Michael Livshin <mlivshin@bigfoot.com>
2351 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): brought
2352 the yucky, ugly and nasty conditional compilation back. sorry,
2353 but it was either that or requiring GAWK to build Guile.
2354 (lots of places): removed the code that implemented the old GC
2357 * init.c (scm_boot_guile_1): removed the code conditioned on
2358 !GUILE_NEW_GC_SCHEME.
2360 * __scm.h: (GUILE_NEW_GC_SCHEME): removed.
2362 * gc.c (scm_protect_object, scm_unprotect_object): change the
2363 implementation to more efficient (at least in the time complexity
2364 sense). the calls should now also be thread-safe -- I suspect
2365 that people expect them to be. (thanks to Han-Wen Nienhuys)
2366 (lots of places): removed the code that implemented the old GC
2369 * hashtab.c (scm_hash_fn_create_handle_x): add missing
2370 SCM_REALLOW_INTS before return. I really wonder about the
2371 possible interactions between hashtables, threads & GC. it
2372 doesn't look healthy at all.
2374 2000-05-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2376 * unif.c (scm_bit_count): Fixed the parameter checks. Thanks to
2379 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
2381 * __scm.h (SCM_DEBUG_CELL_ACCESSES), gc.h (SCM_): Added as a new
2382 debug option to verify all accesses to cells actually access
2383 objects on the heap.
2385 * gc.h (SCM_VALIDATE_CELL): Added. Only performs validation if
2386 SCM_DEBUG_CELL_ACCESSES is set to 1.
2388 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
2389 SCM_SET_CELL_OBJECT): Use SCM_VALIDATE_CELL to check every cell
2392 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
2394 * gh_data.c (gh_scm2chars, gh_scm2shorts, gh_scm2longs,
2395 gh_scm2floats, gh_scm2doubles): Change !SCM_NIMP to SCM_IMP.
2397 * gc.c (scm_cellp): Fixed and simplified.
2399 * throw.c (JBJMPBUF, SETJBJMPBUF, SCM_JBDFRAME, SCM_SETJBDFRAME,
2400 make_jmpbuf, scm_init_throw): Now using double cells to represent
2401 jump buffers when using debug extensions.
2405 2000-05-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
2407 * gh.h gh_data.c gh_funcs.c (gh_new_procedure*, gh_chars2byvect,
2408 gh_shorts2svect, gh_longs2ivect, gh_ulongs2uvect, gh_floats2fvect,
2409 gh_doubles2dvect, gh_doubles2scm, gh_define, gh_lookup,
2410 gh_module_lookup): Accept const pointers as parameters.
2412 * gh.h gh_data.c (gh_int2scmb): Deprecated.
2414 2000-05-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
2416 * __scm.h (SCM_DEBUG_REST_ARGUMENT): Renamed from
2417 SCM_DEBUG_REST_ARGUMENTS in order to clarify that we don't test
2418 the actual arguments in the list, but rather the rest argument as
2419 a list of arguments.
2421 * validate.h (SCM_VALIDATE_REST_ARGUMENT): Added.
2423 * async.c (scm_noop), eval.c (scm_map, scm_for_each), list.c
2424 (scm_list_star, scm_append, scm_append_x), ports.c
2425 (scm_close_all_ports_except), ramap.c (scm_array_map_x,
2426 scm_array_for_each), regex-posix.c (scm_make_regexp), stacks.c
2427 (scm_make_stack), strings.c (scm_string_append), struct.c
2428 (scm_make_struct, scm_make_vtable_vtable): Validate rest arguments.
2430 * dynl.c (DYNL_GLOBAL, sysdep_dynl_link, kw_global, sym_global,
2431 scm_dynamic_link, scm_init_dynamic_linking), dynl.h
2432 (scm_dynamic_link): Removed possibility to pass flags to
2433 scm_dynamic_link, as it had no effect anyway.
2435 * filesys.c (scm_fcntl): Made single optional rest argument into
2436 a standard optional argument.
2438 * hooks.c (scm_run_hook): A list of rest arguments is never
2441 * list.c (scm_append, scm_append_x), stacks.c (scm_make_stack),
2442 strings.c (scm_string_append): Don't perform half-hearted checks
2443 to see whether the rest argument forms a proper list any more, use
2444 SCM_VALIDATE_REST_ARGUMENTS instead.
2446 * ports.c (scm_close_all_ports_except): Accept empty list of rest
2449 * posix.c (scm_convert_exec_args), print.c (scm_simple_format):
2450 Simplify verification of rest argument.
2452 * stacks.c (scm_make_stack), stacks.h (scm_make_stack), throw.c
2453 (ss_handler, handler_message): Make first mandatory rest argument
2454 of scm_make_stack into a standard mandatory argument.
2456 * unif.c (scm_transpose_array, scm_enclose_array,
2457 scm_array_in_bounds_p), unif.h (scm_transpose_array,
2458 scm_enclose_array, scm_array_in_bounds_p): Make first mandatory
2459 rest argument into a standard mandatory argument.
2461 2000-05-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
2463 * __scm.h: Added SCM_DEBUG as default debug option. (Thanks to
2464 Keisuke Nishida for the suggestion.) Added debug option
2465 SCM_DEBUG_REST_ARGUMENTS.
2467 * eval.c (scm_map, scm_for_each): Make sure all lists have the
2468 same length. Also, removed redundant parameter checks.
2470 2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
2472 * Makefile.am: Let 'make clean' remove *.x and *.doc files.
2474 * __scm.h: Improved explanation of giving options to make.
2476 * __scm.h (SCM_DEBUG_TYPING_STRICTNESS), tags.h
2477 (SCM_STRICT_TYPING, SCM_DEBUG_TYPING_STRICTNESS): Renamed
2478 SCM_STRICT_TYPING to SCM_DEBUG_TYPING_STRICTNESS and moved the
2479 corresponding declaration and comment to __scm.h.
2481 * _scm.h (errno), gc.h (SCM_CELLPTR, SCM_PTR_LT), numbers.c
2482 (scm_remainder, scm_modulo), numbers.h (SCM_SRS, SCM_MAKINUM,
2483 SCM_INUM): Removed conditionally compiled code for Turbo C.
2485 * gdbint.c (gdb_maybe_valid_type_p): Eliminated call to scm_tag.
2486 That check can be assumed to be redundant except for very rare
2487 conditions that actually indicate broken heap data.
2489 2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
2491 * numbers.c (scm_logcount, scm_integer_length): Reordered
2494 2000-05-15 Gary Houston <ghouston@arglist.com>
2496 * stime.c (scm_strftime): don't reset TZ if zone is an empty
2497 string. append a "0" to the zone for TZ.
2499 2000-05-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
2501 * numbers.c (scm_logbit_p, scm_bit_extract): Reordered dispatch
2504 (scm_bit_extract): Fixed handling of bignums.
2506 2000-05-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
2508 * async.c (scm_sys_gc_async_thunk), chars.h (SCM_ICHRP, SCM_ICHR,
2509 SCM_MAKICHR), continuations.h (SCM_SETJMPBUF), error.c
2510 (scm_sysmissing), error.h (scm_sysmissing), evalext.c

2514 'serial-array-map!), smob.c (scm_newsmob), smob.h (scm_smobfuns,
2515 scm_newsmob), tag.c (scm_tag), tag.h (scm_tag), tags.h
2516 (scm_tc16_flo, scm_tc_flo, scm_tc_dblr, scm_tc_dblc): Wrapped
2517 deprecated code between #if (SCM_DEBUG_DEPRECATED == 0) #endif.
2519 * fports.c (scm_fport_buffer_add), ports.c (scm_input_port_p,
2520 scm_output_port_p), print.c (scm_get_print_state), validate.h
2521 (SCM_VALIDATE_CHAR): Replace use of deprecated macros
2522 SCM_INPORTP, SCM_OUTPORTP, SCM_ICHRP by SCM_INPUT_PORT_P,
2523 SCM_OUTPUT_PORT_P, SCM_CHARP, respectively.
2525 2000-05-14 Gary Houston <ghouston@arglist.com>
2527 * stime.c (scm_strftime): if HAVE_TM_ZONE is not defined, hack the
2528 TZ environment variable so that the %Z format returns the zone
2529 from the input vector instead of the system default.
2531 from Keisuke Nishida:
2532 * fports.c (scm_setvbuf): minor docstring fix.
2533 * ports.h (scm_generic_fgets): obsolete prototype deleted.
2535 2000-05-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
2537 * __scm.h: Added new section for debugging options.
2539 (SCM_DEBUG_DEPRECATED): If 1, no deprecated code is included to
2540 help developers to get rid of references to deprecated code.
2542 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_UNEGFIXABLE,
2543 SCM_FIXABLE, SCM_FLOBUFLEN): These macros are no longer provided
2544 as part of the interface and are marked as deprecated in the
2547 * numbers.c (scm_make_real, scm_make_complex): Inlined the
2548 corresponding macros SCM_NEWREAL and SCM_NEWCOMPLEX,
2551 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX, SCM_INEXP, SCM_CPLXP,
2552 SCM_REAL, SCM_IMAG, SCM_REALPART, scm_makdbl, SCM_SINGP,
2553 SCM_NO_BIGDIG, SCM_NUM2DBL, scm_dblproc): Deprecated.
2555 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
2557 * gc.h (scm_cell, SCM_CELL_WORD, SCM_CELL_OBJECT,
2558 SCM_SET_CELL_WORD, SCM_SET_CELL_OBJECT): Scheme cells now consist
2559 of two scm_bits_t values instead of two SCM values, because it is
2560 legal for cell entries to hold values that are not scheme objects.
2562 (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR):
2563 Use SCM_SETC[AD]R to modify contents of pairs.
2565 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
2567 * numbers.c (IS_INF, isfinite): Added FIXME comment.
2569 (scm_abs, scm_magnitude): Make these two independent of each
2570 other. scm_abs now reports an error if given a complex argument.
2572 (scm_istr2flo, scm_integer_p). Use SCM_REAL_VALUE instead of
2573 SCM_REALPART if the object is known to be real.
2575 (scm_init_numbers): No need to use SCM_NEWREAL macro for speed
2578 * numbers.h (SCM_SINGP): Set to 0 instead of SCM_BOOL_F.
2580 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
2582 * eq.c (scm_eqv_p): Separate handling of real and complex
2583 values. Remove #ifdef SCM_BIGDIG #endif test.
2585 * eval.c (SCM_CEVAL, SCM_APPLY), gh_data.c (gh_scm2floats,
2586 gh_scm2doubles), hash.c (scm_hasher), ramap.c (scm_array_fill_int,
2587 ramap_rp, scm_array_map_x), random.c (vector_scale,
2588 vector_sum_squares), unif.c (scm_make_uve, scm_array_p,
2589 scm_array_set_x): Use SCM_REAL_VALUE instead of SCM_REALPART if
2590 the object is known to be real. Use SCM_COMPLEXP instead of
2591 deprecated SCM_CPLXP. Use SCM_INEXACTP instead of deprecated
2594 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
2596 * numbers.c: No need to include unif.h.
2598 (IS_INF): Returned to old test for now: x == x + 1 will not work
2599 for large numbers due to rounding errors.
2600 Thanks to Kalle Olavi Niemitalo.
2602 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
2604 * numbers.c (scm_divbigdig): Removed outdated comment.
2606 (scm_number_to_string, scm_string_to_number, scm_number_p,
2607 scm_real_p, scm_integer_p, scm_inexact_p, scm_gr_p, scm_leq_p,
2608 scm_geq_p, scm_make_rectangular, scm_make_polar,
2609 scm_inexact_to_exact): Added comments.
2611 (add1, scm_init_numbers): Removed add1.
2613 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
2615 * numbers.c (IS_INF): The new test is x == x + 1. The old test
2616 x == x/2 did not work for zero values. Thanks to Han-Wen Nienhuys
2619 (scm_number_to_string, scm_sum, scm_difference, scm_two_doubles,
2620 scm_num2long, scm_num2long_long, scm_num2ulong): Reordered
2623 2000-05-09 Marius Vollmer <mvo@zagadka.ping.de>
2625 * scmsigs.c (take_signal): Execute SCM_ASYNC_TICK for SIGSEGV,
2626 SIGILL and SIGBUS signals. These signals are not continuable and
2627 must be handled for real right away.
2629 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
2631 * numbers.c (scm_zero_p, scm_positive_p, scm_negative_p,
2632 scm_real_part, scm_imag_part, scm_magnitude,
2633 scm_inexact_to_exact): Reordered dispatch sequence.
2635 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
2637 * feature.c: No need to include "libguile/smob.h"
2639 (scm_loc_features, features, scm_add_feature, scm_init_feature):
2640 Removed variable 'scm_loc_features' as a pointer to the SCM value
2641 holding the features list. Using variable 'features' instead,
2642 which holds the interned pair. Thus, SCM_SETCDR can be used
2643 instead of pointer trickery.
2645 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
2647 * alist.c (scm_acons): Use SCM{_SET}?_CELL_OBJECT as long as a
2648 cell is not known to be a valid pair.
2650 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
2652 * eval.c (ASRTSYNTAX, scm_m_body, scm_m_letrec1): Removed
2653 ASRTSYNTAX. Using SCM_ASSYNT instead.

2659 (bodycheck): Removed.
2661 * stacks.c (stack_depth, read_frame, read_frames): Removed
2662 redundant calculation of size, minimized some variable scopes.
2664 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
2666 * pairs.c (scm_cons, scm_cons2): Use SCM{_SET}?_CELL_OBJECT as
2667 long as a cell is not known to be a valid pair.
2669 (scm_pair_p): Eliminated redundant SCM_IMP test.
2671 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
2673 * eval.c (scm_m_body, scm_macroexp, unmemocopy, scm_eval_args,
2674 scm_deval_args): Eliminated redundant SCM_IMP tests.
2676 * hashtab.c (scm_ihashx, scm_sloppy_assx, scm_delx_x), weaks.c
2677 (scm_make_weak_key_hash_table, scm_make_weak_value_hash_table,
2678 scm_make_doubly_weak_hash_table): Fixed critical sections.
2679 Thanks to Keisuke Nishida.
2681 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
2683 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest):
2684 Fixed some goto-related initialization bugs (introduced by me).
2686 2000-05-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
2688 * numbers.h (SCM_INUM0): Uses SCM_MAKINUM instead of SCM_PACK.
2690 * dynl.c (dynl_obj, DYNL_OBJ, get_dynl_obj): Removed.
2692 (DYNL_FILENAME, DYNL_HANDLE): Use SCM_CELL... macros instead of
2695 (SET_DYNL_HANDLE): Added.
2697 (scm_dynamic_object_p): Simplified.
2699 (scm_dynamic_unlink, scm_dynamic_func): Changed comment. Deliver
2700 better error message when accessing unlinked dynamic objects.
2701 Eliminated call to get_dynl_obj.
2703 2000-05-03 Marius Vollmer <mvo@zagadka.ping.de>
2705 * scmsigs.c (orig_handlers) [!HAVE_SIGACTION]: Fix declaration to
2706 be an array of function pointers instead of being a pointer to an
2707 array returning function. Thanks to Kalle Olavi Niemitalo!
2709 2000-05-03 Dirk Herrmann <D.Herrmann@tu-bs.de>
2711 * numbers.c (scm_divbigbig, scm_divbigint), numbers.h
2712 (scm_divbigbig, scm_divbigint): Don't return zero any more to
2713 indicate that a division has a remainder, return SCM_UNDEFINED
2714 instead. It is improbable that anyone actually used these
2715 functions outside of numbers.c. For this reason and due to the
2716 change in behaviour the functions are static now. Thus, if
2717 surprisingly there are users of these functions they will at least
2720 * numbers.c: Removed #ifdef SCM_BIGDIG #endif in those functions,
2721 that already have a clean dispatch order. Note: SCM_BIGDIG is
2724 * numbers.c (scm_inexact_p): Simplified.
2726 * numbers.c (scm_num_eq_p, scm_less_p, scm_max, scm_min,
2727 scm_product, scm_num2dbl, scm_angle): Reordered dispatch
2728 sequence, thereby fixing some comparisons of SCM values with
2731 * numbers.c (scm_divide): Division by zero of inums leads to an
2732 error now. (Formerly, an infinite number was returned.)
2734 Respect the fact, that scm_divbigbig does now return SCM_UNDEFINED
2735 if a division has a remainder.
2737 2000-05-02 Gary Houston <ghouston@arglist.com>
2739 * Makefile.am (INCLUDES): add ${INCLTDL} (thanks to Tim Mooney).
2741 2000-05-02 Dirk Herrmann <D.Herrmann@tu-bs.de>
2743 * numbers.c (scm_logtest, scm_division): Reordered dispatch
2744 sequence, thereby fixing some comparisons of SCM values with

2759 call to scm_makdbl with a call to scm_make_real or
2760 scm_make_complex, depending on whether the imaginary part is known
2763 2000-05-01 Gary Houston <ghouston@arglist.com>
2765 * scmsigs.c: fix the definition of orig_handlers for the case
2766 that HAVE_SIGACTION is not defined (thanks to
2767 Kalle Olavi Niemitalo).
2769 * Makefile.am: remove include_HEADERS (was libguile.h)
2770 libguile.h: moved to top level directory.
2772 2000-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
2774 * numbers.c (SCM_SWAP): Moved to the top of the file to allow for
2777 * numbers.c (scm_modulo, scm_gcd, scm_lcm, scm_logand, scm_logior,
2778 scm_logxor): Reordered dispatch sequence, thereby fixing some
2779 comparisons of SCM values with integer constants.
2781 * number.c (scm_logtest): Removed some redundant SCM_{N}?IMP
2784 2000-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
2786 * numbers.c (scm_quotient, scm_remainder): Removed code that was
2787 conditionally compiled based on BADIVSGNS. BADIVSGNS does not
2788 occur anywhere else throughout guile.
2790 * numbers.c (scm_quotient): Fixed parameter number in error
2793 * numbers.c (scm_remainder): Reordered dispatch sequence.
2795 2000-04-25 Gary Houston <ghouston@arglist.com>

2810 * procs.c (scm_init_iprocs), procs.h (scm_subr, scm_iproc,
2811 scm_dsubr, scm_init_iprocs): Removed.
2813 * procs.h (SCM_SUBRF, SCM_DSUBRF): Access the cell words
2814 directly instead of casting a cell to a C struct.
2816 2000-04-22 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2818 Better modularization of GC extensions through new C level GC
2821 * weaks.c (scm_weaks_prehistory): New function: Add

2844 (scm_before_gc_c_hook, scm_before_mark_c_hook,
2845 scm_before_sweep_c_hook, scm_after_sweep_c_hook,
2846 scm_after_gc_c_hook): New C level hooks.
2847 (scm_after_gc_hook): New Scheme level hook.
2848 (scm_gc_sweep): Moved scanning of weak vectors to weaks.c.
2849 (scm_igc): Moved initialization of scm_weak_vectors and the call
2850 to scm_guardian_gc_init to respective module.

2873 (DEFS): Added. automake adds -I options to DEFS, and we don't
2875 Removed all -I options except for the root source directory and
2876 the root build directory.
2878 * numbers.c (scm_odd_p, scm_even_p): Use SCM_WRONG_TYPE_ARG
2879 instead of SCM_ASSERT (0, ...). (Some compilers will complain
2880 about control reaching end of function otherwise, and, besides,
2881 the new code is not less clear.)
2883 * gc.c (scm_must_malloc, scm_must_realloc, scm_must_free): Added
2884 calls to malloc debugging functions.

2900 scm_quotient): Reordered dispatch sequence to first handle
2901 immediates, second handle bignums and finally handle generic
2902 functions respectively signal wrong type arguments. Hopefully
2903 this will allow for easier separation when goops is integrated.
2905 2000-04-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
2907 * gc.c (which_seg): Use SCM2PTR to convert a non immediate SCM
2908 variable into a pointer to a heap cell.
2910 * gc.c (scm_mark_locations, scm_cellp, init_heap_seg,

2916 SCM_UNDEFINED instead.
2918 * weaks.c (scm_make_weak_vector): Fix assignment of zero to a
2919 vector element. (Still to be improved)
2921 2000-04-19 Dirk Herrmann <D.Herrmann@tu-bs.de>

2949 realloc:ing scm_subr_table ("what" instead of "who").
2951 * numbers.c (scm_adjbig): Ditto.
2953 Tue Apr 18 08:22:41 2000 Greg J. Badros <gjb@cs.washington.edu>
2955 * validate.h: Do not cast to (unsigned) in SCM_VALIDATE_INUM_RANGE
2956 when testing high-end of the range. Mikael Djurfeldt noticed this
2957 anomaly -- thanks Mikael!
2959 2000-04-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
2961 * unif.c (l2ra): Don't eliminate the call to scm_array_set_x
2962 itself, as was done in the previous 'patch'. (Thanks to Radey

2977 unsigned long and signed long arrays and clarified the way the
2978 access is performed.
2980 * ramap.c (scm_array_map_x, raeql), read.c (scm_lreadr), stacks.c
2981 (narrow_stack), unif.c (scm_cvref, scm_uniform_array_read_x,

2987 * struct.h (SCM_SET_VTABLE_DESTRUCTOR): Treat the struct data as
2988 a field of scm_bits_t values.
2990 * unif.c (l2ra): Don't test result of scm_array_set_x against
2991 zero: It is always SCM_UNSPECIFIED.

2995 * script.c (scm_compile_shell_switches): Also enable
2996 record-positions when given the --debug option. (Thanks to Diego

3192 * async.h: kill the scm_async_t struct. having a heap cell
3193 pretending to be a C struct is not helthy, and is not needed here

3263 * guardians.c (scm_guardian_zombify): mark all zombies in a
3264 separate loop after processing all the currently known live
3265 guardians, so as to not introduce order dependencies (thanks to
3266 Gary Houston). note that the order problems are still there if
3267 some guardians are themselves zombies, but that's a sick case that
3268 I'm not going to worry about.
3269 also, make another outer loop to process zombified
3270 guardians (which are uncovered while marking zombies).

3540 remember when updating the list of free cells.
3542 (SCM_FREEP, SCM_MARKEDP): Use SCM_CELL_TYPE to access the type
3545 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
3547 * pairs.h (SCM_CAR, SCM_CDR, SCM_SETCAR, SCM_SETCDR): Use
3548 SCM_CELL_OBJECT and SCM_SET_CELL_OBJECT. This change implies that
3549 with strict type checking enabled these macros will only work if
3550 given valid SCM parameters.
3552 (SCM_GCCDR): Moved to tags.h.
3554 * tags.h (SCM_GCCDR): Moved here from pairs.h.
3556 2000-03-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
3558 * tags.h (SCM2PTR, PTR2SCM): Moved to gc.h.
3560 * pairs.h (scm_cell, SCM_CELLPTR, SCM_CELL_WORD*, SCM_CELL_OBJECT*,
3561 SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*, SCM_CELL_TYPE,
3562 SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK, SCM_PTR_GT,
3563 SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC, SCM_NEWCELL,
3564 SCM_NEWCELL2): Moved to gc.h.
3566 (SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR, SCM_SETAND_CDR,
3567 SCM_SETOR_CAR, SCM_SETOR_CDR): Moved to gc.h. These names should
3568 be changed, though, since the macros are not only pair related.
3572 * gc.h (SCM2PTR, PTR2SCM, scm_cell, SCM_CELLPTR, SCM_CELL_WORD*,
3573 SCM_CELL_OBJECT*, SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*,
3574 SCM_CELL_TYPE, SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK,
3575 SCM_PTR_GT, SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC,
3576 SCM_NEWCELL, SCM_NEWCELL2, SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR,
3577 SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR): Moved here from
3580 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
3582 * tags.h (SCM_STRICT_TYPING): New macro that, if defined,
3583 activates strict compile time type checking for variables of
3585 (SCM, SCM_PACK, SCM_UNPACK): Define according to whether
3586 SCM_STRICT_TYPING or SCM_VOIDP_TEST are defined.
3587 (SCM_EQ_P): Defined as a macro equivalent for eq?.
3589 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
3591 * tags.h (SCM_POINTERS_MUNGED): Removed.
3593 * gc.c (scm_gc_sweep, init_heap_seg): Removed use of
3594 SCM_POINTERS_MUNGED, thus fixing some illegal casts to SCM.
3596 2000-03-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
3598 * pairs.h (SCM_CELL_OBJECT, SCM_CELL_OBJECT_[0-3],
3599 SCM_SET_CELL_OBJECT, SCM_SET_CELL_OBJECT_[0-3], SCM_CELL_TYPE,
3600 SCM_SET_CELL_TYPE): Added a set of low level macros for accessing
3602 (SCM_CELL_WORD_[0-3]): Renamed from the SCM_CELL_WORD[0-3].
3604 * procs.h, procs.c: Instead of SCM_{SET_}?CELL_WORD[12], use the
3605 newly introduced SCM_{SET_}?CELL_OBJECT_[12] macros.
3607 2000-03-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3609 * tags.h: Disabled definition of SCM_VOIDP_TEST.
3611 Defining SCM as void * introduces problems which haven't been
3612 handled yet. Developers who work with these issues can enable it
3613 in their working copies.
3615 Disabling this definition exposes a set of newly introduced and
3616 older misuses of types which causes warning messages during
3617 compilation. We'll fix this successively.
3619 * gc.c (scm_mark_locations): Changed * (SCM **) X --> * (SCM *) X
3620 in order to obtain a value of type SCM.
3621 (scm_cellp): Updated with new changes to scm_mark_locations.
3623 * continuations.h (SCM_SETJMPBUF): Cast second arg into SCM.
3625 * continuations.c (scm_make_cont): Removed cast of size_t into
3628 * symbols.h (SCM_SETCHARS): Cast second arg into SCM.
3630 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
3632 * numbers.h (SCM_SETNUMDIGS): Use SCM_BIGSIZEFIELD macro for
3633 shifting, not constant. Thanks to Dale P. Smith.
3635 * numbers.c (scm_sum, scm_difference): Don't test a SCM value
3636 for being less than zero. Decode it to a C value first. Again,
3639 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
3641 * numbers.h, ramap.c, struct.h, vectors.h: Don't use SCM2PTR for
3642 non scheme values. If raw data is stored in SCM variables, it has
3643 to be accessed using SCM_UNPACK until a better solution is found.
3645 2000-03-22 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3647 * tags.h (SCM_ECONSP, SCM_NECONSP): More corrections of
3648 pointer-arithmetic induced by the SCM_PACK/UNPACK change.
3650 * print.c (scm_iprin1): SCM_PACK/UNPACK corrections.
3652 * gc.c (scm_gc_sweep): SCM_PACK/UNPACK corrections.
3654 * eval.c (SCM_CEVAL, scm_unmemocar): SCM_PACK/UNPACK corrections.
3656 * dynwind.c (scm_swap_bindings): SCM_PACK/UNPACK corrections.
3658 * async.c, __scm.h: Removed lots of the old async click logic. It
3659 is possible to reinsert it by defining GUILE_OLD_ASYNC_CLICK in
3660 __scm.h. Let's try this out and dump the old code after the
3661 threads reorganization.
3662 (set-tick-rate, set-switch-rate): Conditionally removed.
3664 2000-03-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3666 * gc.c (scm_gc_mark): Bugfix 1: The recent SCM_PACK/UNPACK change
3667 made SCM values into pointers. This turned an arithmetic
3668 computation of the address of the vcell into a pointer-arithmetic
3669 one, thereby screwing up marking of structs.
3670 Bugfix 2: Removed incompletely introduced loop variable `j' used
3671 when protecting the tail array of a struct.
3673 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
3675 * struct.h (SCM_STRUCT_DATA): Don't cast SCM values to pointers.
3677 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
3679 * symbols.h, symbols.c (scm_strhash): Declare the string
3680 parameter as constant, since it is not modified.
3682 * symbols.c (scm_intern_obarray_soft,
3683 scm_sysintern0_no_module_lookup): Can now pass constant strings
3684 to scm_strhash without need for casting.
3686 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
3688 * vectors.h (SCM_VELTS, SCM_VELTS_AS_STACKITEMS): Don't cast SCM
3689 values to pointers. Use SCM2PTR instead.
3691 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
3693 * async.c (scm_set_tick_rate, scm_set_switch_rate): Don't unpack
3694 results of SCM_INUM.
3696 2000-03-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3698 * init.c (scm_boot_guile_1): Renamed GUILE_GC_TRIGGER_1 -->
3699 GUILE_MIN_YIELD_1, GUILE_GC_TRIGGER_2 --> GUILE_MIN_YIELD_2.
3700 GUILE_MIN_YIELD_X now take *positive* fractions of heap size.
3702 * gc.c, gc.h (SCM_MIN_YIELD_1, SCM_MIN_YIELD_2,
3703 min_yield_fraction, min_yield, adjust_min_yield): Renamed from
3704 SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2, gc_trigger_fraction,
3705 gc_trigger, adjust_gc_trigger.
3707 * gc.c (alloc_some_heap): Further improvement of minimal heap size
3709 (SCM_MAX): New macro.
3710 (scm_freelist_t): New field: collected_1. Previous amount of
3712 (gc_sweep_freelist_finish): Trigger based on two last values of
3713 freelist->collected to avoid unnecessary allocation due to
3715 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2):
3716 Adjusted to 45000 cells, 40% and 40%. Gives quick startup
3717 without extra heap allocation.
3719 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
3721 * numbers.h (SCM_MAKINUM): The parameter to SCM_MAKINUM should
3722 already be a C value. No need to unpack it.
3724 * numbers.c (scm_long_long2num): Cast the parameter to scm_bits_t
3725 if we know it fits into an inum.
3727 * ramap.c (ramap_rp): An scm_tc7_[ui]vect object does point to a
3728 field of long values. In contrast, SCM_VELTS accesses a field of
3731 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3733 * gc.c (scm_gc_stats): Inserted explanation of local_scm_mtrigger
3735 (scm_gc_yield_1): New variable: Holds previous yield. Used to
3736 make better judgements.
3737 (gc_sweep_freelist_finish): Inserted explanation of use of
3740 * print.h, stacks.h, options.c, options.h: Changed C++
3743 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
3745 * tags.h (SCM2PTR, PTR2SCM): Use SCM_PACK / SCM_UNPACK correctly.
3747 * numbers.h (SCM_INUMP, SCM_MAKINUM, SCM_INUM0, SCM_COMPLEX_REAL,
3748 SCM_COMPLEX_IMAG, SCM_NUMP, SCM_BDIGITS): Use SCM_PACK /
3749 SCM_UNPACK / SCM2PTR correctly.
3751 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3753 * gc.c (adjust_gc_trigger): Improved documentation.
3754 (alloc_some_heap): Since gc_trigger is used against
3755 freelist->collected, this is the value which should be used to
3756 predict minimum growth.
3758 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
3760 * eval.h: Fix mixup of packed/unpacked SCM values. (Thanks
3761 Thien-Thi Nguyen for the patch.)
3763 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
3765 * numbers.c (scm_ash): Fixed typing problems with the second
3766 parameter and added some documentation. (Thanks Thien-Thi Nguyen
3767 for indicating the problem.)
3769 2000-03-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3771 * gc.c, gc.h (scm_gc_yield): New variable.
3772 (adjust_gc_trigger): Use scm_gc_yield.
3773 (alloc_some_heap): Use scm_gc_yield instead of
3774 scm_gc_cells_collected.
3776 * coop-threads.c: Addd #include "root.h", #include "strings.h".
3778 * debug.c: Added #include "root.h". (Thanks to Thien-Thi Nguyen.)
3780 * gc.c (scm_gc_for_newcell, adjust_gc_trigger): Improved GC
3781 trigger adjustmeant: Take yield (freed cells) for all freelists
3783 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Tuned
3784 to 50000 cell heap with 45% trigger.
3785 (scm_gc_cells_collected): Reintroduced.
3786 (SCM_HEAP_SIZE): New macro.
3787 (scm_gc_sweep): Reintroduced correct computation of
3788 scm_cells_allocated.
3789 (scm_freelist_t): Corrected commentary for field `cluster_size':
3790 Clustersize counts objects, not cells; New member
3791 `clusters_allocated'.
3793 2000-03-19 Michael Livshin <mlivshin@bigfoot.com>
3795 * *.[hc]: add Emacs magic at the end of file, to ensure GNU
3798 2000-03-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3800 * threads.h: Added #include "libguile/throw.h". (Thanks to
3803 2000-03-18 Michael Livshin <mlivshin@bigfoot.com>
3805 * tags.h: (SCM_DOUBLE_CELLP, SCM_NDOUBLE_CELLP): new macros (bad
3806 names, anyone got any better ones?)
3808 * gc.h: (typedef struct scm_freelist_t) remove from here.
3810 * gc.c: (CELL_UP, CELL_DN) made these macros take additional
3811 parameter (the span).
3812 (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK) new macros.
3813 (typedef struct scm_freelist_t) moved here from gc.h, it had no
3814 business being externally visible.
3815 (typedef struct scm_heap_seg_data_t) renamed from
3816 scm_heap_seg_data, to be style-compliant.
3817 (scm_mark_locations) if the possible pointer points to a
3818 double-cell, check that it's properly aligned.
3819 (init_heap_seg) align double-cells properly, work with the
3820 assumption that the segment size divides cleanly by cluster size.
3821 (round_to_cluster_size) new function.
3822 (alloc_some_heap, make_initial_segment) use round_to_cluster_size
3823 to satisfy the new init_heap_seg invariant.
3825 2000-03-18 Dirk Herrmann <D.Herrmann@tu-bs.de>

3882 2000-03-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3884 * gc.c, gc.h: Cleanup of the change of 2000-03-15.
3885 Cluster sizes are now independent of GC trigger values.
3886 GUILE_GC_TRIGGER_n can now specify a relative trigger value:
3887 A negative integer gives fraction of total heap size in percent.
3888 (SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Default values set to -40.
3890 * init.c (scm_boot_guile_1): Introduced new variable
3891 GUILE_MAX_SEGMENT_SIZE; New environment variable names:
3892 GUILE_INIT_SEGMENT_SIZE_1, GUILE_GC_TRIGGER_1,
3893 GUILE_INIT_SEGMENT_SIZE_2, GUILE_GC_TRIGGER_2
3895 2000-03-16 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3897 * __scm.h (GC_FREE_SEGMENTS): Disable this until we have made
3898 freeing of segment work with the new GC scheme. (Thanks to
3899 Michael Livshin.) Oops, also happened to make GUILE_NEW_GC_SCHEME
3900 the default, but I'll let this change stay in CVS Guile since this
3901 code is not expected to contain serious bugs.
3903 2000-03-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3905 * gc.c, gc.h (scm_map_free_list): Define also if GUILE_DEBUG is
3907 (scm_free_list_length): New procedure (GUILE_DEBUG).
3908 Fixed a small but serious bug introduced by the previous change.
3910 * gc.c (scm_gc_sweep): Moved variable n_objects to inner sweep
3911 loop and declare as register.
3913 * gc.c (scm_gc_sweep): Sigh... forgot to clear private freelists
3916 Wed Mar 15 08:27:04 2000 Greg J. Badros <gjb@cs.washington.edu>
3918 * fluids.c: Docstring patch from Keisuke Nishida. Some
3919 reindentation, too, and a couple formals renamed. Should
3920 fluid-set! return UNSPECIFIED instead of a value?
3922 Wed Mar 15 08:24:58 2000 Greg J. Badros <gjb@cs.washington.edu>
3924 * Makefile.am: Separate out DOT_X_FILES and DOT_DOC_FILES, and
3925 generate the latter from the concrete listing of the former. Then
3926 make guile-procedures.txt depend on DOT_DOC_FILES instead of
3927 *.doc, so that rebuilding it works.
3929 Wed Mar 15 08:12:14 2000 Greg J. Badros <gjb@cs.washington.edu>
3931 * libguile.h: Include libguile/validate.h. Thanks Keisuke Nishida!
3933 * guile-snarf.awk.in: Replace docstring line-ending \n" and \n\n"
3934 with nothing and \n, respectively. Thanks Keisuke Nishida for
3935 noticing this problem.
3937 2000-03-15 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3939 * __scm.h (GUILE_NEW_GC_SCHEME): Define this if you want to test a
3940 new way of allocating heap. It makes Guile fast, but still
3943 * gc.c, gc.h, pairs.h, init.c: Implementation of a new way of
3944 allocating heap. The basic idea is to trigger GC every Nth
3945 allocated cell and grow heap when free list runs out. The scheme
3946 has been extended so that GC isn't triggered until all remaining
3947 cells are used. The implementation is also prepared for
3948 development in the direction of POSIX threads.
3950 * gc.c (SCM_EXPHEAP): In order to grow by a factor of 1.5,
3951 SCM_EXPHEAP should return half of the heap size.
3953 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3955 The following change to init.c is only enabled if Guile was
3956 configured with --enable-guile-debug.
3958 * init.c (scm_i_getenv_int): New function.
3959 (scm_boot_guile_1): Use the environment variables
3960 GUILE_INIT_HEAP_SIZE, GUILE_INIT_HEAP_SIZE2 to select heap size if
3961 they exist. (This may be replaced by a Scheme level mechanism in
3964 * objprop.c (s_scm_set_object_property_x): Use scm_assq instead of
3965 scm_assoc. (Thanks to Keisuke Nishida.)
3967 2000-03-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3969 * eval.c, lang.c, lang.h (scm_lisp_nil, scm_lisp_t): Renamed from
3970 scm_nil, scm_t. (Thanks to Keisuke Nishida.)
3972 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3974 * init.c (scm_boot_guile_1): Use same initial segment size for
3975 1-word and 2-word segments. Having the smaller size causes Guile
3976 to GC too often. Obviously something needs to be done to allow
3977 for a smaller 2-word segment without this to happen. (The amount
3978 of heap for each type should be automatically adapted to the
3979 application somehow.)
3981 [Almost all of these changes should be documented in the NEWS
3984 * gc.h (scm_freelist_t): New type.
3986 * pairs.h (SCM_NEWCELL, SCM_NEWCELL2): Use new style freelists.
3988 * gc.c (SCM_INIT_HEAP_SIZE): Changed from 32768 --> 40000 so that
3989 all of Guile basics fits into one segment and there suitable room
3991 (SCM_EXPHEAP): Now takes an argument. Grow by a factor of 1.5
3993 (scm_freelist, scm_freelist2): Now of type scm_freelist_t.
3994 Freelists now contains information about object span, cells
3995 collected and amount of cells in heap segments belonging to the
3997 (scm_heap_size, scm_gc_cells_collected): Removed.
3999 * init.c (scm_boot_guile_1): Make 2-word segment 8K (512 cells).
4001 * Makefile.am (libguile_la_LDFLAGS): Bumped library version
4004 * __scm.h eq.c, eval.c, gc.c, gc.h, gh_data, hash.c, numbers.c,
4005 numbers.h, objects.c, ramap.c, random.c, unif.c, unif.h: Extensive
4006 rewrite of handling of real and complex numbers.
4007 (SCM_FLOATS, SCM_SINGLES): These #ifdef conditionals have been
4008 removed along with the support for floats. (Float vectors are
4011 * tags.h (scm_tcs_bignums): Removed.
4012 (scm_tc16_bigpos, scm_tc16_bigneg): Replaced by scm_tc16_big.
4013 Use SCM_BIGSIGN(x) to test for sign!
4014 (scm_tc16_big): The new bignum type.
4015 (SCM_REAL_PART, SCM_IMAG_PART): Removed.
4017 * numbers.h (SCM_BIGSIGN): Sign moved to bit 16.
4018 (scm_makdbl): Deprecated.
4019 (SCM_NEWREAL, SCM_NEWCOMPLEX): New macros.
4020 (SCM_SINGP): Deprecated.
4022 (SCM_INEXP, SCM_CPLXP): Deprecated.
4023 (SCM_INEXACTP, SCM_COMPLEXP): New macros.
4024 (SCM_COMPLEX_REAL, SCM_COMPLEX_IMAG): Renamed from
4025 SCM_REAL, SCM_IMAG (and now only valid for complex numbers).
4026 (SCM_REAL, SCM_IMAG): New, *deprecated*, selectors which work both
4027 for doubles and complex numbers.
4028 (SCM_REAL_VALUE): New selector for doubles.
4029 (scm_double_t, scm_complex_t): New types.
4032 * numbers.c (scm_floprint, scm_floequal): Removed.
4033 (scm_print_real, scm_print_complex, scm_real_equalp,
4034 scm_complex_equalp): New functions.
4036 * unif.c (scm_makflo): Removed.
4038 * smob.h (SCM_SMOB_PREDICATE): New macro.
4039 (SCM_NEWSMOB2, SCM_RETURN_NEWSMOB2, SCM_NEWSMOB3,
4040 SCM_RETURN_NEWSMOB3): New macros.
4042 1999-11-21 Michael Livshin <mlivshin@bigfoot.com>
4044 The following changes implement primitive support for double cells
4045 (i.e. four-word cells) and change the representation of some
4046 things to multi-cells instead of cons+malloc. (Applied and
4049 * pairs.h (SCM_NEWCELL2): double-cell variants of SCM_NEWCELL.
4050 (SCM_CELL_WORD, SCM_CELL_WORDLOC, SCM_SET_CELL_WORD): primitive
4051 multi-cell access macros (used by the ones below).
4052 (SCM_CELL_WORD[0-3], SCM_SET_CELL_WORD[0-3]): multi-cell access
4055 * gc.c (scm_freelist2): multi-cell freelists.
4056 (inner_map_free_list): map_free_list, parameterized on ncells.
4057 "nn cells in segment mm" was misleading for ncells > 1; changed to
4058 "objects". still print cells too, though.
4059 (scm_map_free_list): rewritten using inner_map_free_list.
4060 (scm_check_freelist): get freelist as parameter, since now we have
4062 (scm_debug_newcell2): multi-cell variants of
4064 (scm_gc_for_newcell): take ncells and freelist pointer as
4066 (scm_gc_mark): add case for tc7_pws (procedures with setters are
4068 (scm_gc_sweep): don't free the float data, since it's not malloced
4070 (init_heap_seg): didn't understand what n_new_objects stood for,
4071 so changed to n_new_cells.
4072 (make_initial_segment): new function, makes an initial segment
4073 according to given ncells.
4074 (scm_init_storage): call make_initial_segment, for ncells={1,2,3}.
4076 * numbers.c (scm_makdbl): no malloc'ing needed, so the
4077 {DEFER,ALLOW}_INTS thing removed.
4079 * numbers.h (struct scm_dbl): changed to represent a double cell,
4080 with the number in the second half.
4082 * dynwind.c: changed the wind-guards representation to double
4085 * procs.c, procs.h: changed the procedure-with-setter representation
4088 * async.c, async.h: made async representation a double cell.
4090 * dynl.c: made dynamic_obj representation a double cell.
4092 2000-03-13 Gary Houston <ghouston@arglist.com>
4094 * ports.c (flush_void_port): renamed to flush_port_default.
4095 (end_input_void_port): renamed to end_input_default.
4097 * init.c (scm_standard_stream_to_port): create a void port instead
4098 of opening /dev/null if the standard file descriptors are bad.
4099 advantages: no portability problems, doesn't waste a file descriptor,
4100 simplifies the code (thanks to Marius for the idea).
4102 * vports.c (s_scm_make_soft_port): call scm_port_non_buffer.
4104 * void ports: make reading from a void port give EOF instead of
4106 * ports.c (s_scm_sys_make_void_port): modified docstring.
4107 (fill_input_void_port): new proc.
4108 (scm_init_ports): set up fill_input_void_port.
4109 * ports.c (scm_port_non_buffer): new proc.
4110 (scm_void_port): call scm_port_non_buffer.
4112 * fports.c (scm_setvbuf): docstring: remove the fcntl documentation
4113 which was incorrectly appended.
4115 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4117 * guile-doc-snarf.in: Don't use absolute path for `sed'. (Note
4118 that we can't use autoconf for this. Autoconf itself relies on
4119 the existence of `sed' somewhere on your path.) (Thanks to Dirk
4122 2000-03-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
4124 * Makefile.am (libguile_la_SOURCES): Moved iselect.c here from
4125 EXTRA_libguile_la_SOURCES.
4127 * iselect.h: Always declare scm_internal_select.
4129 * iselect.c (scm_internal_select): Added SCM_ASYNC_TICK at the
4130 end. Also let scm_internal_select be a real function also when
4133 * __scm.h (SCM_TICK): Oops! Forgot to put SCM_ASYNC_TICK here...
4135 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4137 * __scm.h (SCM_ALLOW_INTS, SCM_REALLOW_INTS): Removed call to
4138 SCM_ASYNC_TICK. (This is a preparation for POSIX threads support,
4139 and kind of an experiment: Will this cause problems?)
4141 Sun Mar 12 13:26:30 2000 Greg J. Badros <gjb@cs.washington.edu>
4143 * Makefile.am: Added *.doc to DISTCLEANFILES.
4145 2000-03-12 Gary Houston <ghouston@arglist.com>
4147 * fports.c (scm_fdes_to_port): call fcntl F_GETFL to test that
4148 the fdes is valid before doing anything else. check that
4149 the file descriptor supports the modes required.
4150 (scm_fport_buffer_add): don't throw an error if fstat doesn't
4151 work: just use the default buffer size.
4153 * throw.c: change an outdated comment about scm_internal_catch
4154 BODY: it doesn't take a jumpbuf arg.
4156 * init.c (scm_standard_stream_to_port): install a handler in case
4157 scm_fdes_to_port throws an error. don't check here whether the
4158 file descriptor is valid, since scm_fdes_to_port will do that.
4159 set the revealed count depending on whether the port got the
4160 standard file descriptor.
4161 (stream_body_data): new type.
4162 (stream_body, stream_handler): new procs.
4164 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
4166 * stacks.c, stacks.h, struct.c, tags.h, unif.c (scm_bits_t):
4167 Renamed from SCMWORD.
4169 * tags.h (SCM_NCELLP): Removed (SCMWORD).
4171 * arbiters.c (SCM_ARB_LOCKED): Use SCM_UNPACK_CAR.
4173 * async.c, boolean.h, debug.c, dynl.c, dynwind.c, eval.c, eval.h,
4174 feature.h, filesys.h, fluids.h, fports.c, fports.h, gc.c, gc.h,

4178 stacks.h, strports.c, struct.c, struct.h, tag.c, tags.h,
4179 throw.c, unif.c, unif.h, variable.h, vectors.h, weaks.c,
4180 weaks.h (SCM_PACK, SCM_UNPACK, SCM_UNPACK_CAR): Renamed from
4181 SCM_ASSCM, SCM_ASWORD, SCM_CARW).
4183 * numbers.h (SCM_SRS, SCM_INUM): Corrected SCM_ASSCM/ASWORD fixes.
4185 * alist.c, eval.c, net_db.c, posix.c, print.c, snarf.h, struct.c,
4186 tags.h: Fixed copyright notices.
4188 * struct.c, coop-threads.c: SCM_ASSCM/ASWORD fixes.
4190 2000-03-12 Marius Vollmer <mvo@zagadka.ping.de>
4192 * init.c (scm_standard_stream_to_port): Check whether the file
4193 descriptor is valid and substitute "/dev/null" when not.
4195 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
4197 * coop-defs.h (struct timespec): Conditionally defined.
4199 * coop.c (coop_condition_variable_timed_wait_mutex): Use ETIMEDOUT
4202 * readline.c (match_paren): Bugfix: First arg to select is not
4203 number of descriptors but the number of the highest descriptor +
4206 This is a preliminary attempt at a cleanup of the threads support
4207 code. It moves things to better places, makes arguments more
4208 consistent with the POSIX API (which is used in GNOME's glib), and
4209 adds new functionality.
4211 * readline.c (scm_init_readline): Added new arg to scm_init_mutex.
4213 * coop-defs.h (scm_mutex_trylock): New macro: alias for
4215 (scm_cond_init): Changed definition to
4216 coop_new_condition_variable_init.
4218 * coop.c: #include <errno.h>
4219 (coop_timeout_qinsert): Moved here from iselect.c
4220 (coop_new_mutex_init, coop_new_condition_variable_init): New
4221 functions. The strange names are temporary. Use scm_mutex_init
4222 and scm_cond_init instead.
4223 (coop_mutex_trylock): New function. Uses errno.h:EBUSY. errno.h
4224 is ANSI C, but should we check for individual error codes in
4226 (coop_condition_variable_timed_wait_mutex): New function.
4227 (coop_key_create, coop_setspecific, coop_getspecific,
4228 coop_key_delete): New functions.
4230 * iselect.c (coop_timout_qinsert): Moved to coop.c
4232 2000-03-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
4234 * pairs.h (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR,
4235 SCM_SETOR_CDR): Corrected SCM_ASSCM/WORD fixes.
4237 * tags.h (SCM_VOIDP_TEST): Renamed from VOIDP_TEST.
4240 * objects.h (SCM_CLASS_FLAGS, SCM_OBJ_CLASS_FLAGS,
4241 SCM_SET_CLASS_INSTANCE_SIZE), struct.h (SCM_STRUCT_VTABLE_DATA),
4242 proc.h (SCM_CLOSCAR): SCM_ASSCM/WORD fixes.
4244 * eval.c (scm_lookupcar1): Inserted SCM_ASWORD in expressions
4247 2000-03-11 Dale P. Smith <dpsm@en.com>, applied by Greg J. Badros, <gjb@cs.washington.edu>
4249 * numbers.c (scm_copy_big_dec, scm_copy_smaller, scm_big_ior,
4250 scm_big_xor, scm_big_and, scm_big_test): Added new lowlevel bignum
4251 logical functions from SCM.
4253 (logand, logior, logxor, logtest, logbit?): Extended scheme
4254 logical functions to use bignums from SCM.
4256 (lognot): Removed call to `SCM_VALIDATE_INUM' that prevented
4257 lognot from using bignums.
4259 Thu Mar 9 11:33:25 2000 Greg J. Badros <gjb@cs.washington.edu>
4261 * vectors.h (SCM_VELTS_AS_STACKITEMS): Added this macro to help in
4262 eliminating some warnings.
4264 * unif.c, strports.c, print.c, options.c: Fix some warnings on
4267 * gc.c, gc.h: Added scm_return_first_int(), and added comment re:
4268 what the scm_return_first* functions do.
4270 2000-03-09 Han-Wen Nienhuys <hanwen@cs.uu.nl>, applied by Greg J. Badros, <gjb@cs.washington.edu>
4272 * libguile/*.[ch]: make a distinction between SCM as a generic
4273 name for a Scheme object (now a void*), and SCM as 32 bit word for
4274 storing tags and immediates (now a long int). Introduced
4275 SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious
4276 code in the process: arbiter.c (use macros), unif.c (scm_array_p),
4278 Wed Mar 8 10:15:59 2000 Greg J. Badros <gjb@cs.washington.edu>
4280 * numbers.c: Use SCM_VALIDATE_LONG_COPY, and longs, not ints, in
4281 various logXXX primitives. Thanks Eric Moore!
4283 Tue Mar 7 08:05:22 2000 Greg J. Badros <gjb@cs.washington.edu>
4285 * run-test, remaining-docs-needed: Added these scripts. The
4286 second one is only temporary until the docstring additions are
4287 complete. run-test may best live on, but is here mostly for
4288 convenience and awareness for now.
4290 * hash.c: Docs, minor cleanup patch from Dirk Herrman.
4292 Thu Mar 2 16:06:58 2000 Greg J. Badros <gjb@cs.washington.edu>
4294 * error.h, error.c: Added `scm_wrong_type_arg_msg' to support
4295 displaying the expected type. Use SCM_LISTn in a couple places
4296 instead of scm_cons-ing by hand.
4298 * __scm.h: Added SCM_ASSERT_TYPE macro.
4300 * validate.h, scm_validate.h: Added the former, as a renamed
4301 version of the latter with SCM_ASSERT_TYPE used in
4302 SCM_MAKE_VALIDATE (instead of just SCM_ASSERT)
4304 * Makefile.am: Rename scm_validate.h to validate.h.
4306 * *.c, *.h: Include validate.h, not scm_validate.h (old name's
4307 prefix was superfluous).
4309 Thu Mar 2 15:33:12 2000 Greg J. Badros <gjb@cs.washington.edu>
4311 * hashtab.c: Improved documentation for lots of functions. Added
4312 handwritten docs for `hash-fold'.
4314 Thu Mar 2 15:13:25 2000 Greg J. Badros <gjb@cs.washington.edu>
4316 * list.c: Added hand-written docs for `del{q,v,ete}1!'.
4318 Thu Mar 2 12:38:30 2000 Greg J. Badros <gjb@cs.washington.edu>
4320 * list.c: Moved append docs to append! Thanks Dirk Hermann. Also,
4321 added append docs from R4RS.
4323 * strings.c: Docstring typo fix, + eliminate unneeded IMP tests.
4324 Thanks Dirk Hermann!
4326 * chars.h: Provide SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR and
4327 deprecate SCM_ICHRP, SCM_ICHR, SCM_MAKICHR. Thanks Dirk Hermann!
4329 * *.h, *.c: Use SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR throughout.
4330 Drop use of SCM_P for function prototypes... assume an ANSI C
4331 compiler. Thanks Dirk Hermann!
4333 Sat Feb 19 12:20:12 2000 Greg J. Badros <gjb@cs.washington.edu>
4335 * ports.c: Made `set-port-column!' and `set-port-line!' each
4336 return SCM_UNSPECIFIED instead of a (not-scheme-object) integer
4337 that caused a seg fault. Also fixed `set-port-column!'s
4338 docstring. Thanks Han-Wen Nienhuys for finding the bug!
4340 Sun Feb 13 19:11:42 2000 Greg J. Badros <gjb@cs.washington.edu>
4342 * arbiters.c, eq.c, gc.c, guardians.c, list.c, ports.c, print.c,
4343 regex-posix.c, scmsigs.c, stime.c, strings.c, variable.c, stime.c,
4344 strings.c, variable.c: Added lots of documentation, cleaned up
4345 some existing documentation. Occasionally changed formal params
4346 to match docs. Also folded an #ifdef into the inners of a
4347 primitive instead of having two copies of the primitive
4348 (`get-internal-real-time', from stime.c)
4350 Sun Feb 13 18:12:19 2000 Greg J. Badros <gjb@cs.washington.edu>
4352 * ports.c: Added docs for primitives missing them. Written by
4355 Sun Feb 13 09:40:36 2000 Greg J. Badros <gjb@cs.washington.edu>
4357 * guile-doc-snarf.in: Use ${AWK} -f guile-func-name-check, not
4358 just execing guile-func-name-check. Thanks Michael Livshin!
4360 Thu Feb 10 11:43:23 2000 Greg J. Badros <gjb@cs.washington.edu>
4362 * guile-snarf.awk.in: Tweak to work with Sun/HP awk, removed some
4363 dead code. Patch from Michael Livshin.
4365 * guile-doc-snarf.in: Tweak to work with Sun/HP sh. Patch from
4368 2000-02-09 Gary Houston <ghouston@arglist.com>
4370 * init.c (scm_init_standard_ports): when stdout is a tty, make the
4371 current-output-port unbuffered by default. this is less confusing
4372 for interactive use. it was line-buffered because of a
4373 performance problem with unbuffered ports, but I think it will be
4376 2000-02-08 Gary Houston <ghouston@arglist.com>
4378 * __scm.h: don't define long_long or ulong_long if HAVE_LONG_LONGS
4381 * stime.c (scm_localtime, scm_mktime): if neither HAVE_TM_ZONE nor
4382 HAVE_TZNAME are defined, use an empty string instead of giving two
4383 spurious compile-time errors.
4385 Tue Feb 8 13:57:46 2000 Greg J. Badros <gjb@cs.washington.edu>
4387 * ports.c: Doc patches from Richard Kim. Pasted from MIT Scheme.
4390 Mon Feb 7 09:07:31 2000 Greg J. Badros <gjb@cs.washington.edu>
4392 * macros.c: Doc patches from Richard Kim. Pasted from scm.texi.
4394 Sun Feb 6 20:26:21 2000 Greg J. Badros <gjb@cs.washington.edu>
4396 * pairs.c: Doc patches from Richard Kim. Pasted from MIT Scheme
4397 (which is GNU GPL'd).
4399 2000-01-31 Gary Houston <ghouston@arglist.com>
4401 * strings.h: don't use SCM_P. don't include <string.h>.
4402 * error.c, gh_data.c, ports.c, script.c, strop.c: include <string.h>.
4404 * strings.c (scm_string_ref): make the 2nd argument compulsory.
4405 previously it defaulted to zero for no good reason that I can see.
4406 use a local variable for SCM_INUM (k). replace
4407 SCM_VALIDATE_INUM_DEF with SCM_VALIDATE_INUM_COPY.
4409 (scm_makfromstr): cosmetic changes.
4411 (scm_string): Accept only chars in the list, not strings, for
4412 conformance to R5RS (particularly for list->string, which is
4413 supposed to be the inverse of string->list.) remove
4414 SCM_DEFER_INTS/SCM_ALLOW_INTS, which is unnecessary since
4415 scm_makstr handles the cell allocation. when reporting wrong-type
4416 arg, don't report the position as 1.
4418 * posix.c (scm_init_posix): intern PIPE_BUF if it's defined.
4420 2000-01-29 Gary Houston <ghouston@arglist.com>
4422 * posix.c (scm_pipe): rewrote the docstring.
4424 * filesys.c (scm_select, retrieve_select_type, get_element,
4425 fill_select_type, set_element): modified so that Scheme
4426 "select" tests port buffers for the ability to provide input
4427 or accept output. Previously only the underlying file descriptors
4428 were checked. Rewrote the docstring.
4430 Thu Jan 27 10:14:25 2000 Greg J. Badros <gjb@cs.washington.edu>
4432 * vectors.c, symbols.c, strorder.c: Documentation cut and pasted
4433 from Gregg Reynolds. Thanks Gregg!
4435 Thu Jan 27 09:59:38 2000 Greg J. Badros <gjb@cs.washington.edu>
4437 * strop.c (scm_i_index): Obfuscated commented-out SCM_DEFINE by
4438 adding "x" prefix to the line so that guile-func-name-check
4439 doesn't complain unnecessarily.
4441 Wed Jan 26 17:33:52 2000 Greg J. Badros <gjb@cs.washington.edu>
4443 * throw.c: Factor out an #ifdef/#else/#endif choice more finely
4444 for maintainability.
4446 * strop.c: Documentation added by Gregg A. Reynolds. Pasted in
4449 Wed Jan 26 10:02:11 2000 Greg J. Badros <gjb@cs.washington.edu>
4451 * tag.c: Added doc for `tag', but mark as deprecated since Mikael
4452 suggests removing tag.c altogether (and using a new `class-of'
4455 * strings.c: Added documentation from Gregg A. Reynolds. Edited
4456 a bit by me to use FOO instead of @var{foo} and to have the
4457 summary come before preconditions on input. Also dropped trailing
4460 * gsubr.c: Do not use SCM_DEFINE for `gsubr-apply'. Register the
4461 function with scm_make_subr_opt w/ last arg of 0 so it is not
4462 visible at the Scheme level. Mikael says that this is the right
4463 thing because the first arg to the proc is the guts of a compiled
4464 closure and shouldn't be exposed to the Scheme level.
4466 Tue Jan 25 17:15:47 2000 Greg J. Badros <gjb@cs.washington.edu>
4468 * sort.c: typo in comment fixed.
4470 * keywords.c: Added documentation.
4472 * guardians.c: Added documentation (could be better).
4474 * gc.c: Added docs for gc-set-debug-check-freelist.
4476 * eq.c: Added docs for eq?, eqv? equal? abridged from R4RS.
4478 * boolean.c: Added docs for `not', `boolean?' (by hand).
4480 Tue Jan 25 13:28:56 2000 Greg J. Badros <gjb@cs.washington.edu>
4482 * random.c: Added documentation, from SLIB page:
4483 http://angela.ctrl-c.liu.se/~calle/scheme/slib_toc.html
4485 Mon Jan 24 17:50:20 2000 Greg J. Badros <gjb@cs.washington.edu>
4487 * variable.c, version.c: Added documentation, written by hand
4488 since I could not find anything already written that was
4491 2000-01-23 Gary Houston <ghouston@arglist.com>
4493 * filesys.c (scm_chown): omit port/fdes support if HAVE_FCHOWN is
4494 not defined (thanks to Richard Y. Kim).
4496 Thu Jan 20 13:00:38 2000 Greg J. Badros <gjb@cs.washington.edu>
4498 * Makefile.in: Removed, this is auto-generated.
4500 Thu Jan 20 11:33:47 2000 Dirk Hermann <dirk@ida.ing.tu-bs.de> --applied 01/20/00 gjb
4502 * list.c: Put some variable initialization code at the point of
4503 declaration; Added a comment for list*; Formatting changes.
4505 * load.c: use SCM_NNULLP to make sure the end of a list is not
4508 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4510 * backtrace.c (scm_display_error_message): Bugfix: Don't use
4511 result of scm_list_p as C boolean.
4512 (scm_display_error_message, scm_set_print_params_x): Use new
4513 validation macros. (Thanks to Dirk Herrmann.)
4515 * net_db.c (scm_resolv_error): Cast result from hstrerror.
4517 * strports.c (st_end_input): Inserted parenthesis to get operator
4520 * list.h (scm_init_list): Removed SCM_P around prototypes.
4522 * fports.c, list.c, numbers.c, ports.c, stime.c, symbols.c,
4523 filesys.c, posix.c: Converted docstrings to ANSI C format and
4524 escaped " occurring inside string literals.
4526 Tue Jan 18 13:21:08 2000 Mikael Djurfeldt <mdj@r11n07-s.pdc.kth.se>
4528 * posix.c (scm_mknod): Escape " occuring inside docstring.
4530 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4532 * alist.c, chars.c, debug.c, dynl.c, dynwind.c, error.c, eval.c,

4538 symbols.c, throw.c, unif.c, vectors.c, version.c, vports.c,
4539 weaks.c: Converted docstrings to ANSI C format.
4541 * filesys.c (scm_chmod), simpos.c (scm_system), version
4542 (scm_version), vports (scm_make_soft_port): Escape " occuring
4545 Mon Jan 17 11:41:22 2000 Greg J. Badros <gjb@cs.washington.edu>
4547 * scm_validate.h: Added SCM_VALIDATE_ULONG_COPY,
4548 SCM_VALIDATE_LONG_COPY
4550 * numbers.c: Use SCM_VALIDATE_ULONG_COPY, instead of
4551 SCM_VALIDATE_INUM_COPY to let bigger numbers be used. Rename a
4552 couple of formal arguments (and fix their uses) to make arguments
4553 match the documentation.
4555 2000-01-14 <mstachow@alum.mit.edu>
4557 * Makefile.am: Augment path when running guile-doc-snarf so
4558 guile-func-name-check is found.
4560 Fri Jan 14 09:34:55 2000 Greg J. Badros <gjb@cs.washington.edu>
4562 * scm_validate.h (SCM_NUM2LONG_DEF): Fix this macro to just use
4563 def, not SCM_MAKINUM(def); thanks Janis Bzerins!
4565 Wed Jan 12 00:06:53 2000 Greg J. Badros <gjb@cs.washington.edu>
4567 * net_db.c (s_scm_inet_makeaddr): Use SCM_NUM2ULONG since that's
4568 the way guile-1.3.4 worked, but #if 0 out the version using
4569 SCM_VALIDATE_INUM_COPY for stricter testing.
4571 Tue Jan 11 18:24:18 2000 Greg J. Badros <gjb@cs.washington.edu>
4573 * guile-doc-snarf.in: Use new $fullfilename for running
4574 guile-func-name-check, and put "$fullfilename" and "$filename" in
4575 quotes at uses to make sure re-splitting on whitespace does not
4576 occur (so filenames w/ embedded whitespace would work okay, though
4577 I sure hope we never have to deal with that! :-) ). Thanks to
4578 Mikael for pointing out the source_dir != build_dir was broken.
4580 Tue Jan 11 17:42:40 2000 Greg J. Badros <gjb@cs.washington.edu>
4582 * scm_validate.h: Added SCM_NUM2LONG_DEF macro. Make
4583 SCM_OUT_OF_RANGE use SCM_MAKINUM, not scm_long2num. Added
4584 SCM_COERCE_ROSTRING macro. Added SCM_VALIDATE_NONEMPTYLIST
4585 macro. Fix SCM_VALIDATE_STRINGORSUBSTR macro to not use SLOPPY
4588 * ports.c (scm_port_closed_p): Validate that the arg is a PORT,
4589 then return whether it's an open port (was validating that it was
4590 an open port -- this was a bug I introduced back in December, but
4591 my careful reading of diffs caught it).
4593 * numbers.c: Recombine the two conditional-compilation paths for
4594 all the log* primitives -- they were split based on #ifndef
4595 scm_long2num; factored out a SCM_LOGOP_RETURN macro, and fixed
4596 some bugs and inconsistencies in the two sets of implementations.
4597 (scm_lognot) Fixed *atrocious* re-use of a SCM as an integer!
4599 * ioext.c: Use SCM_ASSERT_RANGE in a couple places, and
4600 SCM_VALIDATE_INUM_COPY once where it should've been used.
4602 * fluids.c (scm_internal_with_fluids): Use
4603 SCM_VALIDATE_LIST_COPYLEN.
4605 * filesys.c: Use SCM_NUM2LONG instead of SCM_VALIDATE_INUM_COPY;
4606 this is questionable as it relaxes type safety, but other changes
4607 were useful and all SCM_NUM2LONG's should probably be
4608 revisited. Use SCM_OUT_OF_RANGE, SCM_WRONG_TYPE_ARG.
4610 * evalext.c: line-break change on 1 line.
4612 * eval.c (nconc2last): Takes a non-empty list as its first
4613 argument, not just a list.
4615 * dynl.c: Use new SCM_COERCE_ROSTRING macro.
4617 Tue Jan 11 15:44:23 2000 Greg J. Badros <gjb@cs.washington.edu>
4619 * dynl.c, feature.c, filesys.c, fports.c, list.c, load.c,
4620 net_db.c, sort.c, stacks.c, unif.c: Use SCM_WTA, SCM_MISC_ERROR
4623 * symbols.c (scm_sysintern0): Fixed the function name in a
4624 scm_misc_error invocation.
4626 * print.c (scm_simple_format): Do not need SCM_COERCE_SUBSTR, and
4627 use scm_return_first to ward off latent GC bug that Mikael caught.
4629 * async.c: Use SCM_VALIDATE_ASYNC_COPY one place where it wasn't
4630 used before but should've been.
4632 2000-01-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
4634 * snarf.h (SCM_PROC1): Replaced SCM (*) (...) with
4635 SCM_FUNC_CAST_ARBITRARY_ARGS.
4637 Tue Jan 11 13:44:07 2000 Greg J. Badros <gjb@cs.washington.edu>
4639 * guile-func-name-check.in: Added this script to statically check
4640 #define FUNC_NAME, #undef FUNC_NAME in the source.
4642 * sort.c, posix.c: Fix #undef FUNC_NAME lines to not have trailing
4643 redundant comment, semicolon; caught by new guile-func-name-check
4646 * debug.c: Fix mistaken #define FUNC_NAME for scm_make_iloc.
4647 Caught by new guile-func-name-check-script.
4649 * Makefile.am: Added guile-func-name-check to bin_SCRIPTS
4651 * ramap.c: Fix #if 0'd out code to be syntactically acceptable to
4652 guile-func-name-check.
4654 * guile-doc-snarf.in: Run guile-func-name-check on the file before
4657 Tue Jan 11 11:31:10 2000 Greg J. Badros <gjb@cs.washington.edu>
4659 * fports.c, ports.c, ports.h, strports.c, vports.c: Make write
4660 port function take const void*, not void*.
4662 Tue Jan 11 11:18:07 2000 Greg J. Badros <gjb@cs.washington.edu>
4664 * scm_validate.h, chars.c, ports.c, print.c, read.c, strings.c,
4665 strop.c: Use SCM_VALIDATE_ICHR, SCM_VALIDATE_ICHR_COPY instead of
4666 SCM_VALIDATE_CHAR, SCM_VALIDATE_CHAR_COPY. Change made for
4667 consistency with the other macros dealing with immediate
4668 characters. (Similar to INT -> INUM change a week or so ago).
4670 Tue Jan 11 10:41:46 2000 Greg J. Badros <gjb@cs.washington.edu>
4672 * dynl.c, error.c, eval.c, feature.c, filesys.c, fports.c, list.c, load.c,
4673 net_db.c, read.c, socket.c: Update error messages to use ~A for
4674 %s, ~S for %S to work with new `simple-format' format and be
4675 standardized better.
4677 * print.h, print.c (scm_simple_format): Added `simple-format'
4678 primitive. It's the old scm_display_error, with ARGS now a rest
4679 parameter, and the destination first instead of last (and a couple
4680 new capabilities inspired by `format' -- #t as destination means
4681 current-output-port, #f means return the formatted text as a
4684 * gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
4686 * backtrace.c (scm_display_error_message): Rewrote to use
4687 scm_simple_format() procedure.
4689 * __scm.h: Added commented-out #define of GUILE_DEBUG_FREELIST
4691 2000-01-09 Marius Vollmer <mvo@zagadka.ping.de>
4693 Finally applied the libltdl patch from Thomas Tanner, with slight
4696 * DYNAMIC-LINKING: Removed because it is obsolete.
4697 * dynl.c: Use ANSI prototypes.
4698 (sysdep_dynl_link): Use lt_dlopenext instead of lt_dlopen.
4699 * scmconfig.h.in: Do not change, as it is automatically generated.
4701 1999-07-25 Thomas Tanner <tanner@ffii.org>
4703 * dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c: deleted
4705 * Makefile.am: likewise, add INCLTDL (libltdl headers) to
4706 INCLUDES, set dlpreopened files in LDFLAGS, link libguile
4708 * dynl.c: use libltdl if DYNAMIC_LINKING is enabled,
4709 * guile.c: register preloaded modules
4710 * scmconfig.h.in: remove obsolete symbols
4712 2000-01-09 Gary Houston <ghouston@arglist.com>
4714 * These changes should make it unnecessary to call tzset from
4715 Scheme after modifying the TZ environment variable, even if the
4716 system date facilities cache the value.
4717 * stime.c (setzone, scm_localtime): added comments.
4718 (tzset): don't define a noop tzset macro if HAVE_TZSET not defined.
4719 (setzone): don't call tzset.
4720 (restorezone): call tzset only if HAVE_TZSET is defined.
4721 (scm_tzset): don't define if HAVE_TZSET not defined. Change the
4722 doc string to indicate that this procedure isn't likely to do
4724 (scm_localtime, scm_strftime, scm_mktime): call tzset if
4725 LOCALTIME_CACHE is defined.
4727 2000-01-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
4729 * posix.c (scm_sync): Return SCM_UNSPECIFIED.
4731 2000-01-09 Gary Houston <ghouston@arglist.com>
4733 * eval.c: define scm_unbound_variable_key ('unbound-variable).
4734 scm_lookupcar1: throw an error with key 'unbound-variable instead
4735 of 'misc-error when an unbound variable is encountered.
4737 * filesys.c (scm_mkdir, scm_rmdir, scm_getcwd, scm_select,
4738 scm_symlink, scm_readlink, scm_lstat),
4739 posix.c (scm_setpgid, scm_setsid, scm_ctermid, scm_tcgetpgrp,
4740 scm_tcsetpgrp, scm_uname, scm_setlocale, scm_mknod, scm_nice,
4742 simpos.c (scm_system),
4743 stime.c (scm_times, scm_strptime):
4744 move the HAVE_XXX feature tests out of the procedure bodies.
4745 don't use SCM_SYSMISSING.
4746 scm_validate.h (SCM_SYSMISSING): removed.
4747 error.h, error.c (scm_sysmissing): comment that this is deprecated.
4748 see ChangeLog entry for 1999-12-28.
4750 Sat Jan 8 19:52:04 2000 Greg J. Badros <gjb@cs.washington.edu>
4752 * scm_validate.h (SCM_VALIDATE_BOOL_COPY): Fix typo.
4754 Sat Jan 8 17:06:46 2000 Greg J. Badros <gjb@cs.washington.edu>
4756 * backtrace.c: Fix spelling typo in a comment.
4758 * snarf.h: Use new SCM_DOCS macro to encapsulate the non SCM_INIT
4759 text. Reformatted some of the expansions.
4761 Fri Jan 7 15:50:46 2000 Greg J. Badros <gjb@cs.washington.edu>
4763 * scm_validate.h (SCM_OUT_OF_RANGE): Use scm_out_of_range_pos to
4764 report the position of the argument.
4766 * error.h, error.c (scm_out_of_range_pos): Added this function to
4767 take extra "pos" argument, the position number of the errant
4770 * debug.c: Use SCM_OUT_OF_RANGE instead of scm_out_of_range.
4772 * snarf.h: Use SCM_HERE and SCM_INIT as names, not SCM_NOTSNARF
4773 and SCM_SNARFING. Also put the %%% in the SCM_INIT since Mikael
4774 prefers that and I'm reasonably indifferent.
4776 Fri Jan 7 15:03:32 2000 Greg J. Badros <gjb@cs.washington.edu>
4778 * snarf.h: Factor out differences between C++ and non-C++ into
4779 SCM_FUNC_CAST_ARBITRARY_ARGS macro. Modify all the snarf macro
4780 definitions to use SCM_NOTSNARF and SCM_SNARFING macros (like
4781 Mikael's macros, below, but changed names and SCM_SNARFING no
4782 longer expands to include %%% -- that must appear in the argument
4783 so that the token appears at the call-site as a reminder).
4785 2000-01-07 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
4787 * snarf.h (SCM_INSITU, SCM_INIT): New snarf macros for use in user
4788 snarf macro definitions.
4790 2000-01-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4792 * chars.c (scm_integer_to_char): Use Greg's nice
4793 SCM_VALIDATE_INUM_RANGE macro for argument checking for closer
4796 Thu Jan 6 11:48:49 2000 Greg J. Badros <gjb@cs.washington.edu>
4798 * *.c, snarf.h: Replace GUILE_PROC1 with SCM_DEFINE1 throughout.
4800 Thu Jan 6 11:22:53 2000 Greg J. Badros <gjb@cs.washington.edu>
4802 * Makefile.am (ETAGS_ARGS): Switch to SCM_DEFINE, SCM_DEFINE1
4803 instead of GUILE_PROC.
4805 Thu Jan 6 11:21:49 2000 Greg J. Badros <gjb@cs.washington.edu>
4807 * alist.c: Do not report mismatch errors on some uses of `tmp' (do
4808 this by using SCM_ARG2 instead of `2' in the SCM_VALIDATE_CONS
4811 Thu Jan 6 09:54:33 2000 Dirk Herrmann <dirk@ida.ing.tu-bs.de> --gjb applied
4813 * scm_validate.h: Remove some redundant NIMP tests.
4815 * alist.c: minimize scope of the tmp variables, and initialize
4816 them when declared. The strange SCM_NIMP tests are replaced by
4817 SCM_CONSP tests that more closely reflect the intended semantics.
4818 However, we don't get a performance penalty here, because the
4819 SCM_CONSP test was performed by the ALISTCELL test anyway. * The
4820 extremely ugly use of ASRTGO macros was removed: The calls to
4821 ASRTGO were not encapsulated by "#ifndef SCM_RECKLESS", but got a
4822 label parameter that only exists when SCM_RECKLESS is not defined.
4823 This works, because ASRTGO itself is defined in a way that it only
4824 makes use of the label parameter if SCM_RECKLESS is not defined
4825 (shudder!). Does guile make at all use of the possibility to
4826 define SCM_RECKLESS? * Codesize is likely to be reduced, since
4827 instead of two calls to SCM_ASSERT performed by the ALISTCELL test
4828 we now only get one test.
4830 * list.c: Use SCM_NNULLP, not SCM_NIMP as appropriate. Also use
4831 SCM_NULLP instead of SCM_IMP. Drop use of "register" keyword on
4832 some variables in `list?'. Fix `reverse' and `reverse!'
4833 primitives to handle improper lists better.
4835 Wed Jan 5 11:24:53 2000 Greg J. Badros <gjb@cs.washington.edu>
4837 * *.[ch]: Whitespace changes -- added space after SCM_VALIDATE_*
4838 macros and SCM_DEFINE macros to match GNU coding standards.
4840 Wed Jan 5 11:04:24 2000 Greg J. Badros <gjb@cs.washington.edu>
4842 * *.[ch]: Replace GUILE_PROC w/ SCM_DEFINE.
4844 Wed Jan 5 10:59:06 2000 Greg J. Badros <gjb@cs.washington.edu>
4846 * *.[ch]: Replace SCM_VALIDATE_INT w/ SCM_VALIDATE_INUM for
4847 better consistency with the names of other SCM_VALIDATE_ macros
4848 and better conformance to guile naming policy.
4850 Wed Jan 5 10:50:39 2000 Greg J. Badros <gjb@cs.washington.edu>
4852 * ports.c (s_scm_close_all_ports_except): Use SCM_ARG1 in a
4853 SCM_VALIDATE instead of 1 to avoid a check on the argument (since
4854 it's not the actual name of the formal).
4856 * guile-snarf.awk.in: Do argument/number mismatch checking and
4857 print warnings in an Emacs compile-mode parseable format.
4859 * struct.c: Use SCM_ASSERT_RANGE instead of SCM_ASSERT w/
4860 SCM_OUTOFRANGE as 3rd argument.
4862 * random.c: Fix argument/number mismatch (that I introduced :-( ).
4864 * __scm.h: Do not #define SCM_ARG* when snarfing;
4865 lets us distinguish between 1 and SCM_ARG1 when snarfing as only
4866 the former (using the number) requires the argument to match the
4867 formal in the current argument snarfing check.
4869 * snarf.h: Give new definition of SCM_ASSERT when in
4870 snarfing mode to output a lexically-identifiable sequence that the
4871 guile-snarf.awk script uses to verify argument/position matching.
4873 * ramap.c: Remove extraneous #undef FUNC_NAME.
4875 Wed Jan 5 08:36:38 2000 Greg J. Badros <gjb@cs.washington.edu>
4877 * guile-doc-snarf.awk.in: Removed -- guile-snarf.awk.in is the
4878 current version of the same functionality; it writes the .x output
4879 to stdout instead of directly into the file.
4881 Wed Jan 5 08:15:04 2000 Greg J. Badros <gjb@cs.washington.edu>
4883 * unif.c, symbols.c, strings.c, stacks.c, random.c, print.c,
4884 posix.c: Eliminated a bunch of SCM_NIMP(..)s that are now
4885 redundant with the safer macros. Patch from Dirk Hermann applied
4886 by hand. Thanks Dirk!
4888 * scm_validate.h: Added SCM_VALIDATE_VECTOR_OR_DVECTOR for some
4891 * ramap.c: whitespace change.
4893 Tue Jan 4 14:21:35 2000 Greg J. Badros <gjb@cs.washington.edu>
4895 * options.c, objects.c, keywords.c, gc.c: Some redundant SCM_NIMP
4896 removals from Dirk Hermann.
4898 * alist.c: Rename formals to match the parameter names in the
4899 documentation, updates to documentation. Thanks Dirk Hermann!
4901 2000-01-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4903 * eval.c (SCM_CEVAL): Reverse order of
4904 scm_stack_checking_enabled_p and SCM_STACK_OVERFLOW_P
4905 (Thanks to Brad Knotwell.)
4907 Mon Jan 3 08:30:02 2000 Greg Harvey <Greg.Harvey@thezone.net> (applied --01/03/00 gjb)
4909 * gc.c (scm_debug_newcell): Added SCM_SETCAR of the newly
4912 * pairs.h: Added a comment about the need for the SCM_SETCAR in
4915 Mon Jan 3 08:25:19 2000 Greg J. Badros <gjb@cs.washington.edu>
4917 * dynl-vms.c, debug.c, coop-threads.c, backtrace.c, eval.c: More
4918 SCM_NIMP tests that were redundant are now eliminated. Patches
4919 from Dirk Hermann applied by hand.
