66
67 2001-03-08 Neil Jerram <neil@ossau.uklinux.net>

71
72 2001-03-08 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
73
74 * ramap.c (racp): Removed optimization which caused array copying
75 to fail if the two arrays shared storage. Re-inserted the IVDEP
76 macros removed in the change of 2000-03-09. (Don't really have a
77 complete grasp of what they are for, but they seem to be necessary
78 on Crays. This needs testing!) Thanks to Miroslav Silovic.
79
80 * hash.c (scm_string_hash): Don't downcase characters.
81
82 2001-03-07 Mikael Djurfeldt <mdj@linnaeus.mit.edu>

93
94 2001-03-07 Keisuke Nishida <kxn30@po.cwru.edu>

97 (*.doc): Add dependency on guile-snarf.awk.in.
98
99 * guile-snarf.awk.in: Neglect spaces at the end of
100 SCM_SNARF_DOCSTRING_END. Skip lines "# NN ..." in the
101 middle of docstrings. (To avoid the problem with gcc-2.96.)
102
103 2001-03-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
104
105 * coop-threads.c (scm_call_with_new_thread), load.c
106 (scm_primitive_load, scm_sys_search_load_path), random.c
107 (scm_c_default_rstate), struct.c (scm_make_struct_layout,
108 scm_struct_ref, scm_struct_set_x): Don't use SCM_ASSERT to
109 (potentially) issue a scm-misc-error or wrong-num-args error
110 message.
111
112 * load.c (scm_search_path): Use SCM_ASSERT_TYPE to give details
113 about the expected type with the wrong-type-arg error message.
114
115 * smob.c (scm_make_smob): Abort on misuse of smob - it indicates
116 a C level bug that can't be fixed from scheme anyway.
117
118 2001-03-05 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
119
120 * eval.c (scm_m_letstar): Removed check for duplicate bindings.
121 Duplicate bindings are OK in a let* since a let* is semantically
122 equivalent to a nested set of let:s.
123
124 2001-03-05 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
125
126 * print.c (scm_print_options): Fixed texinfo in docstring.
127
128 * net_db.c (scm_getserv, scm_getproto, scm_getnet): Return #f if
129 the underlying functions getservent, getprotoent or getnetent
130 return NULL instead of signalling an error.
131
132 2001-03-04 Gary Houston <ghouston@arglist.com>
133
134 * socket.c (scm_fill_sockaddr): don't allow buffer overflows when
135 taking an unexpectedly large filename for an AF_UNIX socket from
136 bind/connect/sendto (thanks to Martin Grabmueller).
137
138 * socket.c (scm_sock_fd_to_port, SCM_SOCK_FD_TO_PORT): removed the
139 former and adjusted the latter.
140 (scm_socket, scm_socketpair): cosmetic changes.
141 (scm_getsockopt, scm_setsockopt): declare optlen as int, not
142 size_t as socklen_t substitute. don't restrict args/return values
143 to INUM: allow full range of int or size_t.
144 (scm_fill_sockaddr): check arguments before allocating memory, to
145 avoid leakage. use malloc, not scm_must_malloc.
146 (scm_connect, scm_bind, scm_sendto): use int, not size_t as socklen_t
147 substitute. free the sockaddr structure before throwing an error.
148 (scm_init_add_buffer): procedure removed, together with its static
149 buffer scm_addr_buffer, which wouldn't be thread safe. instead,
150 define a macro MAX_ADDR_SIZE and declare the buffer where needed.
151 (scm_accept, scm_getpeername, scm_getsockname, scm_recvfrom,
152 scm_sendto): use a local buffer instead of scm_addr_buffer.
153 adjust for new SCM_SOCK_FD_TO_PORT. use int for address size,
154 not size_t.
155 (scm_recvfrom): set addr->sa_family to AF_UNSPEC before the recvfrom
156 call to detect whether recvfrom could be bothered to set the address.
157 (scm_init_socket): don't call scm_init_addr_buffer.
158
159 2001-03-04 Dirk Herrmann <D.Herrmann@tu-bs.de>

164 scm_stable_sort_x, scm_stable_sort), stacks.c (scm_make_stack,
165 scm_last_stack_frame), symbols.c (scm_sym2vcell, scm_sym2ovcell),
166 unif.c (scm_list_to_uniform_array, scm_uniform_vector_length,
167 scm_transpose_array, scm_enclose_array, scm_array_in_bounds_p,
168 scm_uniform_vector_ref, scm_array_set_x, scm_uniform_array_read_x,
169 scm_uniform_array_write, scm_bit_set_star_x, scm_bit_count_star,
170 scm_array_to_list, scm_array_prototype), validate.h
171 (SCM_VALIDATE_NUMBER_COPY): Don't call function scm_wta, call
172 scm_misc_error or scm_wrong_type_arg instead.
173
174 * validate.h (SCM_WTA, RETURN_SCM_WTA): Deprecated.
175
176 2001-03-04 Mikael Djurfeldt <mdj@linnaeus.mit.edu>

179 (scm_sys_tag_body): Added.
180
181 2001-03-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
182
183 * continuations.c (continuation_apply), eval.c (scm_m_lambda,
184 scm_m_letstar, scm_m_letrec1, scm_m_let, SCM_APPLY), eval.h
185 (SCM_EVALIM2), evalext.c (scm_m_generalized_set_x), gc.c
186 (get_bvec, MARK), goops.c (scm_primitive_generic_generic),
187 options.c (scm_options), ports.c (scm_remove_from_port_table),
188 ramap.c (scm_ramapc), read.c (skip_scsh_block_comment, scm_lreadr,
189 scm_lreadparen, scm_lreadrecparen), script.c (script_get_octal,
190 script_get_backslash, script_read_arg), unif.c (scm_cvref): Don't
191 call function scm_wta, call scm_misc_error or scm_wrong_type_arg
192 instead.
193
194 2001-03-04 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
195
196 * goops.c (scm_sys_pre_expand_closure_x): New procedure.

202
203 2001-03-03 Marius Vollmer <mvo@zagadka.ping.de>

208 (scm_c_improper_memq): New function.
209 (scm_m_lambda): Check for duplicate arguments.
210 (scm_ceval, scm_deval): When executing a body: only cons a new
211 toplevel environment frame when it is different from the
212 existing one; use EVALCAR instead of SIDEVAL so that we can properly
213 check for empty combinations; use SCM_EVALIM2 for the same reason
214 in the non-toplevel loop.
215 (nontoplevel_cdrxnoap, nontoplevel_cdrxbegin, nontoplevel_begin):
216 New labels with the meaning of their non-"nontoplevel" partners,
217 but they are used when it is known that the body is not evaluated at
218 top-level.
219 (scm_apply, scm_dapply): use SCM_EVALIM2 to get proper error
220 reporting for empty combinations.
221
222 2001-03-02 Keisuke Nishida <kxn30@po.cwru.edu>

276
277 * validate.h (SCM_ASSERT_RANGE): Use the argument number.
278

306 scm_i_eval.
307 (make_class_from_template): Do not bother to set the current

309 (scm_init_goops): Make scm_module_goops and
310 scm_goops_lookup_closure permanent objects.
311
312 * eval.c (scm_ceval, scm_deval): When evaluating expressions on
313 top level, create a fresh top-level environment for each
314 expression instead of mutating the exisint frame. This is
315 important when that frame is closed over.
316
317 * numbers.c (s_scm_logior) [SCM_DIGSTOOBIG]: Also use
318 SCM_DIGSPERLONG instead of DIGSPERLONG.
319
320 2001-02-21 Marius Vollmer <mvo@zagadka.ping.de>
321
322 * eval.c (scm_ceval, scm_deval): Check for wrong number of args
323 before applying arrow procedure in `cond' and before applying
324 receiver procedure in call-with-current-continuation.
325 (scm_i_eval): Do not invoke scm_copy_tree in argument in SCM_XEVAL
326 macro. The argument is expanded more than one time.
327
328 * numbers.c (scm_logior) [SCM_DIGSTOOBIG]: Correctly use
329 SCM_BIGDIG instead of BIGDIG. Thanks to Steven G. Johnson!

385
386 * numbers.c (scm_lognot), random.c (scm_random,

440
441 2001-02-15 Keisuke Nishida <kxn30@po.cwru.edu>
442
443 * dump.c (scm_undump): Use SCM_CARLOC/SCM_CDRLOC to obtain the
444 address of car/cdr. (Thanks to Dirk Herrmann)
445 Use scm_sizet to obtain the length of strings.
446 (Thanks to Matthias Koeppe)
447
448 2001-02-15 Marius Vollmer <mvo@zagadka.ping.de>
449
450 * symbols.c (scm_mem2symbol): Put a empty statement after the
451 next_symbol label. This is mandated by ANSI, appearantly.
452
453 2001-02-13 Marius Vollmer <marius.vollmer@uni-dortmund.de>
454
455 * gc_os_dep.c: Do not include <linux/version.h>. It makes no
456 sense to compile for a specific kernel version. Do not include
457 <asm/signal.h> while defining __KERNEL__. This hack should no
458 longer be needed and caused problems.
459
460 2001-02-13 Marius Vollmer <mvo@zagadka.ping.de>
461
462 * eval.c (scm_ceval, scm_deval): use `SIDEVAL' instead of
463 SCM_CEVAL when evaluating subforms of `begin' forms. SCM_CEVAL
464 can not deal with immediates.
465
466 2001-02-12 Keisuke Nishida <kxn30@po.cwru.edu>
467
468 * list.c (scm_list_copy): Validate the first argument.

476 function.
477
478 * eval.h (scm_primitive_eval, scm_primitive_eval_x): New
479 prototypes.
480 (scm_i_eval, scm_i_eval_x, scm_eval, scm_eval_x): Changed argument
481 names to better reflect their meaning.
482
483 * eval.c (scm_ceval, scm_deval): Recognize when `begin' is being
484 evaluated at top-level and synronize lookup closure before
485 executing every subform.
486 (scm_primitve_eval_x, scm_primitive_eval): New functions.
487 (scm_eval_x, scm_eval): Reimplement in terms of
488 scm_primitive_eval_x and scm_primitive_eval, respectively.
489
490 2001-02-09 Marius Vollmer <mvo@zagadka.ping.de>
491
492 * macros.c (scm_macro_name, scm_macro_transformer): Use
493 SCM_SMOB_DATA instead of SCM_CDR. Provided by Martin Grabmueller.
494 Thanks!
495
496 2001-02-10 Keisuke Nishida <kxn30@po.cwru.edu>
497
498 * dump.c (scm_store_bytes): Store data size before data.

505
506 2001-02-08 Keisuke Nishida <kxn30@po.cwru.edu>
507
508 * ports.c (scm_unread_char): Take an optional argument.
509
510 2001-02-08 Marius Vollmer <marius.vollmer@uni-dortmund.de>
511
512 * modules.h (scm_selected_module, scm_current_module): Renamed
513 scm_selected_module to scm_current_module to synchronize Scheme
514 and C names.
515 (scm_select_module, scm_set_current_module): Likewise. Changed
516 all uses.
517
518 * ports.c (scm_port_for_each): Make a snapshot of the port table
519 before iterating over it. The table might change while the user
520 code is running. With the snapshot, the user can depend on the
521 fact that each port that existed at the start of the iteration is
522 encountered exactly once. (ice-9 popen) depends on this.
523
524 2001-02-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
525
526 * strings.h (SCM_STRING_MAX_LENGTH): New macro.
527
528 * strings.c (scm_makstr, scm_take_str, scm_make_string): Added
529 range checking for the size parameter. Thanks to Martin
530 Grabmueller for the hint.

533 deferring unnecessary.
534
535 * vectors.c (scm_make_vector): Fixed range checking.
536
537 2001-02-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
538
539 * vectors.h (SCM_VECTOR_MAX_LENGTH): New macro.
540
541 * vectors.c (scm_make_vector, scm_c_make_vector): Improved the
542 checking of the size parameter for type correctness and valid
543 range. Thanks to Rob Browning for reporting the problem. Instead
544 of deferring interrupts, scm_remember_upto_here_1 is used.
545
546 2001-02-05 Keisuke Nishida <kxn30@po.cwru.edu>

572 2001-02-03 Michael Livshin <mlivshin@bigfoot.com>
573
574 * gc.c (DOUBLECELL_ALIGNED_P): new macro, a better-named analog of
575 the deprecated SCM_DOUBLE_CELLP.
576
577 * tags.h (SCM_DOUBLE_CELLP): deprecated.

745
746 2001-01-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
747
748 This patch modifies scm_display_error to perform parameter

827 fixnum-min) special case.
828
829 (scm_big_and): Fix for negative first parameter.

835
836 2001-01-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
837
838 * symbols.c (scm_symbol_bound_p): Fixed comment.

847
848 from Matthias Köppe:
849
850 * objects.h (SCM_SET_ENTITY_SETTER): new macro. SCM_ENTITY_SETTER
851 casts its result, so doesn't yield an lvalue per ANSI C.
852
853 * goops.c (s_scm_sys_set_object_setter_x): use
854 SCM_SET_ENTITY_SETTER.
855 (clear_method_cache): use SCM_SET_ENTITY_PROCEDURE.
856
857 * gc.h (SCM_GC_SET_CARD_BVEC): new macro. SCM_GC_CARD_BVEC casts
858 its result, so doesn't yield an lvalue per ANSI C.
859 (SCM_GC_SET_CARD_FLAGS): ditto for SCM_GC_GET_CARD_FLAGS.
860 (SCM_GC_CLR_CARD_FLAGS): redefined in terms of
861 SCM_GC_SET_CARD_FLAGS.
862 (SCM_GC_SET_CARD_FLAG, SCM_GC_CLR_CARD_FLAGS): ditto.
863
864 * gc.c (INIT_CARD): use the explicit setter macro to set the bvec.
865
866 2001-01-08 Gary Houston <ghouston@arglist.com>
867
868 * validate.h (SCM_VALIDATE_SUBSTRING_SPEC_COPY): new macro.
869 * ioext.c (scm_read_string_x_partial, scm_read_delimited_x),
870 socket.c (scm_recvfrom): use the new macro, plus minor docstring
871 changes.
872 * ioext.c (scm_read_string_x_partial): don't crash if -1 is supplied
873 for fdes. if current input port is used, check that it's a file
874 port.
875
876 2001-01-06 Gary Houston <ghouston@arglist.com>
877
878 * ioext.c (scm_read_string_x_partial): new procedure, implements
879 read-string!/partial.

891 SET_GREEDY, LISTED_P, SET_LISTED, CLR_LISTED, DESTROYED_P,
892 SET_DESTROYED): new defines/macros.
893 (GUARDIAN_LIVE, GUARDIAN_ZOMBIES, GUARDIAN_NEXT): deleted.
894 (add_to_live_list): takes a `guardian_t *' now, not SCM.
895 (guardian_print): print more info.
896 (guardian_apply): check if the guardian is destroyed, and throw an
897 error if so. take one more optional argument `throw_p'.
898 (scm_guard): depending on the value of `throw_p', return a boolean
899 result.
900 (scm_get_one_zombie): remove redundant property test.
901 (guardian_t): represent the various (currently 3, I hope nothing
902 more gets added) boolean fields as bit flags.
903 (scm_guardian_destroyed_p, scm_guardian_greedy_p): new predicates.
904 (scm_destroy_guardian_x): new procedure.
905
906 * guardians.h: added prototypes for `scm_guardian_greedy_p' and

910
911 * fports.c (fport_write): bugfix: handle short writes for
912 unbuffered ports too. optimize the buffered case by minimizing
913 the number of write/flush calls.

924 `weak_keys' and `weak_values' flags out of the inner loop.
925
926 2000-12-29 Michael Livshin <mlivshin@bigfoot.com>
927
928 * guardians.c: (greedily_guarded_prop): deleted.
929 (greedily_guarded_whash): new variable. a doubly-weak hash table
930 used to keep the "greedily guarded" object property. the previous
931 implementation (via primitive object properties) was incorrect due
932 to its only-the-key-is-weak semantics.
933 (scm_guard, get_one_zombie, scm_init_guardians): use/init
934 `greedily_guarded_whash'.
935
936 2000-12-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
937
938 * eval.c (check_map_args), gh_data.c (gh_set_substr,
939 gh_scm2newstr, gh_get_substr, gh_symbol2newstr), print.c
940 (scm_iprin1): Use scm_remember_upto_here_1 instead of
941 scm_remember.

944 scm_remember_upto_here): New functions.
945
946 (scm_remember): Deprecated.
947
948 2000-12-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
949
950 * continuations.c (scm_make_continuation): Make variable cont
951 volatile to let the compiler know that it won't be clobbered by
952 longjmp. (It wouldn't be anyway, but for some reason the compiler
953 is not able to see that.)
954
955 2000-12-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
956
957 This patch re-introduces the unused member "properties" of
958 struct scm_subr_entry as requested by Mikael Djurfeldt.
959
960 * procs.h (scm_subr_entry): Re-introduced member "properties".
961
962 (SCM_SUBR_PROPS): Un-deprecated.
963
964 * procs.c (scm_make_subr_opt, scm_mark_subr_table): Struct
965 scm_subr_entry has a member "properties" again.
966
967 2000-12-28 Michael Livshin <mlivshin@bigfoot.com>
968
969 * guardians.c (mark_dependencies_in_tconc): new function.
970 (mark_dependencies): bug fix. mark the dependencies of the known
971 zombies, too. duh.
972
973 2000-12-24 Michael Livshin <mlivshin@bigfoot.com>
974
975 * gc.c: (scm_gc_mark_dependencies): use SCM_EQ_P for SCMs, not
976 '=='. also, return after calling `scm_gc_mark'.
977
978 2000-12-24 Michael Livshin <mlivshin@bigfoot.com>
979
980 * gc.c: (scm_gc_mark_dependencies): new function. like
981 `scm_gc_mark', but doesn't mark the argument itself. defined
982 using an arrangement similar to that in eval.c: `scm_gc_mark' and
983 `scm_gc_mark_dependencies' are derived from the same "template"
984 by ugly preprocessor magic.
985
986 * gc.h: added prototype for `scm_gc_mark_dependencies'.
987
988 * init.c (scm_init_guile_1): call the renamed
989 `scm_init_guardians'.
990
991 * guardians.h: changed prototypes for `scm_make_guardian' and
992 `scm_init_guardians'.
993
994 * guardians.c (guardian_t): added new fields `greedy_p' and
995 `listed_p'.
996 (GUARDIAN_P): predicate that says whether its argument is a
997 guardian.
998 (GUARDIAN_GREEDY_P, GUARDIAN_LISTED_P): new predicates.
999 (greedy_guardians, sharing_guardians): new variables. hold the
1000 greedy and sharing live guardian lists, respectively.
1001 (first_live_guardian, current_link_field): removed.
1002 (greedily_guarded_prop): new variable. holds the "is greedily
1003 guarded" object property.
1004 (self_centered_zombies): new variable. stores guarded objects
1005 that are parts of cycles.
1006 (add_to_live_list): new function, introduced to decouple marking a
1007 guardian and adding it to the live list.
1008 (guardian_mark): call `add_to_live_list'.
1009 (guardian_print): print whether the guardian is greedy or not.
1010 also change "live" and "zombie" to "reachable" and "unreachable"
1011 respectively, to be less confusing.
1012 (scm_guard): if the guardian is greedy, test whether the object is
1013 already greedily marked. throw an error if so.
1014 (scm_get_one_zombie): if the guardian is greedy, remove the
1015 "greedily guarded" property from the object.
1016 (scm_make_guardian): add a new optional boolean argument which
1017 says whether the guardian is greedy or sharing.
1018 (guardian_gc_init): init the new live lists.
1019 (mark_dependencies): new function.
1020 (mark_and_zombify): new function.
1021 (guardian_zombify): reworked to support the new guardian
1022 semantics. move some logic to `mark_dependencies' and
1023 `mark_and_zombify'.
1024 (whine_about_self_centered_zombies): new function. installed in
1025 the `after-gc-hook' to complain about guarded objects which are
1026 parts of cycles.
1027 (scm_init_guardians): init the new stuff. renamed from
1028 `scm_init_guardian'.
1029
1030 2000-12-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
1031
1032 * procs.h (scm_subr_entry): Removed unused struct member
1033 "properties".
1034
1035 (SCM_SUBR_PROPS): Deprecated.
1036
1037 * procs.c (scm_make_subr_opt, scm_mark_subr_table): Struct
1038 scm_subr_entry does not have a member "properties" any more.
1039
1040 2000-12-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
1041
1042 * procs.h (scm_subr_entry): Removed unused struct member
1043 "documentation".
1044
1045 (SCM_SUBR_DOC): Deprecated.
1046
1047 * procs.c (scm_make_subr_opt): Eliminate use of scm_intern0 in
1048 favor of scm_str2symbol. Similarly, prefer scm_sysintern over
1049 scm_sysintern0.
1050
1051 (scm_make_subr_opt, scm_mark_subr_table): Struct scm_subr_entry
1052 does not have a member "documentation" any more.
1053
1054 2000-12-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
1055
1056 * eval.c (restore_environment): Make sure that changes to the
1057 current environment will take effect when re-entering the dynamic
1058 scope.
1059
1060 2000-12-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
1061
1062 * goops.h (SCM_PUREGENERICP): Include the SCM_STRUCTP test.
1063
1064 * goops.c (scm_sys_invalidate_method_cache_x, scm_m_atdispatch,
1065 scm_pure_generic_p): The SCM_STRUCTP test is implied.
1066
1067 2000-12-20 Gary Houston <ghouston@arglist.com>
1068
1069 * continuations.c (continuation_apply): subtract the length of
1070 continuation->dynenv, not the dynenv itself. I broke it last
1071 time I changed this file. thanks to Bernard Urban.
1072
1073 2000-12-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
1074
1075 * goops.c (remove_duplicate_slots, maplist,
1076 scm_sys_initialize_object, scm_sys_prep_layout_x,
1077 scm_sys_inherit_magic_x, scm_instance_p,
1078 scm_sys_set_object_setter_x, scm_sys_invalidate_method_cache_x,
1079 scm_compute_applicable_methods, scm_m_atdispatch,

1083
1084 * validate.h (SCM_WRONG_NUM_ARGS): New macro.
1085 * goops.h: #include "libguile/validate.h"
1086 (SCM_CLASSP, SCM_GENERICP, SCM_METHODP): Moved from goops.c with
1087 prefix "SCM_".
1088 (SCM_VALIDATE_INSTANCE, SCM_VALIDATE_ACCESSOR, SCM_VALIDATE_CLASS,
1089 SCM_VALIDATE_GENERIC, SCM_VALIDATE_METHOD): New macros.
1090 * goops.c (CLASSP, GENERICP, METHODP): Moved to goops.h with
1091 prefix "SCM_".
1092 (scm_sys_compute_slots, scm_sys_initialize_object,

1123 2000-12-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
1124
1125 * environments.[ch] (scm_system_environment): New variable, will
1126 replace scm_symhash soon. We may decide for a better name and
1127 also to split this up into a set of environments later.
1128
1129 (scm_environments_prehistory): Initialize scm_system_environment.
1130
1131 * init.c (scm_init_guile_1): scm_environments_prehistory requires
1132 storage to be initialized.
1133
1134 2000-12-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
1135
1136 * eval.c (change_environment, inner_eval, restore_environment):
1137 New functions.
1138
1139 (scm_eval): Bring the global variable that holds the current
1140 environment up to date when entering or leaving the scope of the
1141 evaluated code. Thanks to Matthias Koeppe for the bug report.
1142
1143 2000-12-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
1144
1145 * numbers.c (scm_init_numbers): Re-introduced bindings for
1146 most-positive-fixnum and most-negative-fixnum as requested by
1147 Mikael Djurfeldt.
1148
1149 2000-12-12 Dirk Herrmann <D.Herrmann@tu-bs.de>
1150
1151 The variable scm_symbols is made static within symbols.c and
1152 renamed to symbols. The initialization of the symbols hash table
1153 is done in function scm_symbols_prehistory.
1154
1155 * gc.c (scm_init_storage): Don't initialize scm_symbols. Don't
1156 define most-positive-fixnum, most-negative-fixnum and
1157 bignum-radix.
1158
1159 * init.c (scm_init_guile_1): Call scm_symbols_prehistory.
1160
1161 * root.h (scm_symbols): Not in scm_sys_protects any more.
1162
1163 * symbols.c (symbols): Renamed from scm_symbols and made static.
1164
1165 (scm_mem2symbol): scm_symbols is renamed to symbols.
1166

1170
1171 * gc.c (scm_init_storage), root.h (scm_weak_symhash, scm_symbols):
1172 Removed the former scm_weak_symhash hash table. Added scm_symbols
1173 hash table.
1174
1175 * stacks.c (get_applybody): scm_sym2vcell may return #f.
1176
1177 * symbols.c (scm_mem2symbol): This function is now responsible
1178 for creating symbol objects and storing them in the global
1179 scm_symbols hash table.
1180
1181 (scm_str2symbol): Rewritten in terms of scm_mem2symbol.
1182
1183 (scm_sym2vcell): For system bindings, there is now only one
1184 obarray - scm_symhash. If scm_sym2vcell is called to look up a
1185 symbol that can't be found and shall not be created, #f is
1186 returned. Most callers of scm_sym2vcell have expected this
1187 behaviour anyway.
1188
1189 (scm_intern_obarray_soft): Removed reference to scm_weak_symhash
1190 from comment.
1191
1192 (scm_intern_obarray_soft, scm_sysintern0_no_module_lookup): These
1193 functions are not responsible for symbol creation any more, only
1194 for creation of bindings.
1195
1196 (scm_symbol_value0): Don't use scm_intern_obarray_soft to create
1197 a symbol object.
1198
1199 (scm_symbol_interned_p): scm_weak_symhash is removed.
1200
1201 * symbols.[ch] (scm_builtin_weak_bindings): Removed. There are
1202 no weak bindings any more.
1203
1204 2000-12-12 Dirk Herrmann <D.Herrmann@tu-bs.de>
1205
1206 * hooks.c (scm_create_hook), script.c
1207 (scm_compile_shell_switches), snarf.h (SCM_VCELL,
1208 SCM_GLOBAL_VCELL, SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): Create
1209 a binding in one go (instead of first creating a vcell and then
1210 setting its cdr).
1211
1212 2000-12-12 Dirk Herrmann <D.Herrmann@tu-bs.de>
1213
1214 * hash.[ch] (scm_string_hash), symbols.[ch] (scm_string_hash):
1215 Moved function scm_string_hash to hash.c.
1216
1217 2000-12-11 Marius Vollmer <mvo@zagadka.ping.de>
1218
1219 * gc_os_dep.c (scm_get_stack_base) [MSWIN32]: Added detection of

1228 scm_sym_apply_frame, scm_sym_exit_frame, scm_sym_trace,
1229 scm_init_eval), gsubr.c (scm_sym_name, scm_init_gsubr), srcprop.c
1230 (scm_sym_filename, scm_sym_copy, scm_sym_line, scm_sym_column,
1231 scm_sym_breakpoint), variable.c (anonymous_variable_sym):
1232 Initialize symbols by using SCM_(GLOBAL_)?SYMBOL.
1233
1234 * gc.c (scm_i_getenv_int): Moved here from init.c.
1235

1242 Make sure procprops get initialized early.
1243
1244 * keywords.c (scm_c_make_keyword): Report amount of memory freed
1245 by scm_must_free. Use scm_str2symbol instead of scm_sysintern0.

1248 scm_sysintern0.
1249

1251
1252 * threads.h (SCM_MUTEXP): Typo: removed extra parenthesis.
1253
1254 2000-12-08 Keisuke Nishida <kxn30@po.cwru.edu>
1255
1256 * tags.h (SCM_TYP16_PREDICATE): New macro.
1257 * arbiters.c (scm_tc16_arbiter): Typed as scm_bits_t.

1627 * strop.c (scm_i_index): Removed outdated comment.
1628
1629 2000-11-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1630
1631 * struct.c (scm_struct_ref, scm_struct_set_x), symbols.c
1632 (scm_intern_obarray_soft), symbols.h (SCM_ROUCHARS): Eliminate
1633 use of SCM_SYMBOL_UCHARS by using chars instead of unsigned
1634 chars.
1635
1636 (SCM_SYMBOL_UCHARS): Removed.
1637
1638 2000-11-26 Gary Houston <ghouston@arglist.com>
1639
1640 * reimplementation of values, call-with-values as primitives:
1641
1642 * values.c, values.h: new files. use a struct to contain multiple
1643 values, similar to the previous Scheme-level implementation.
1644 * Makefile.am: add values.c, values.h, values.x.
1645 * continuations.c (continuation_apply): support R5RS multiple value
1646 continuations.
1647 * init.c: call scm_init_values.
1648 * struct.h: define SCM_SET_STRUCT_PRINTER.
1649
1650 2000-11-25 Gary Houston <ghouston@arglist.com>
1651
1652 * use an applicable SMOB to represent continuations, instead of a
1653 custom tc7 type. This will make it easier to support R5RS
1654 multiple value continuations, without the use of a Scheme-level
1655 wrapper.
1656
1657 * continuations.c (scm_tc16_continuation, continuation_mark,
1658 continuation_free, continuation_print, continuation_apply):
1659 new SMOB support.
1660 (scm_make_continuation): new procedure, replaces scm_make_cont
1661 with a different interface.
1662 (copy_stack_and_call, scm_dynthrow, scm_init_continuations): rewritten.
1663 (CHEAP_CONTINUATIONS): removed non-working code completely.
1664 (scm_call_continuation): removed.
1665 * continuations.h (struct scm_contregs): add num_stack_items and
1666 stack fields. previously stack was stored following this struct:
1667 use a tail array instead.
1668 (SCM_CONTINUATIONP): new macro.
1669 (SCM_CONTINUATION_LENGTH, SCM_SET_CONTINUATION_LENGTH):
1670 rewritten.
1671 (SCM_SET_CONTREGS): removed.
1672 * tags.h: removed scm_tc7_contin (was tag 61).
1673 * debug.c, gc.c, hash.c, print.c, procprop.c, procs.c:
1674 removed scm_tc7_contin support.
1675 * eval.c: use scm_make_continuation instead of scm_make_cont.
1676 don't set jump buffers here. remove scm_tc7_contin support.
1677 * init.c, root.c: create SMOB continuation for rootcont instead
1678 of scm_tc7_contin. call scm_init_continuations before
1679 scm_init_root.
1680 * root.c: remove support for static jmpbuf. It's not used by
1681 default and I broke it. create SMOB continuation for rootcont.
1682 * stacks.c: use SCM_CONTINUATIONP.
1683
1684 2000-11-24 Matthias Koeppe <mkoeppe@mail.math.uni-magdeburg.de>
1685
1686 * goops.c (filter_cpl, remove_duplicate_slots), goops.h
1687 (SCM_SUBCLASSP): Fix previous change: In contrast to
1688 scm_sloppy_memq the function scm_memq returns #f if the
1689 object was not contained in the list.
1690
1691 2000-11-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
1692
1693 * goops.c: Include validate.h.

1696
1697 (scm_sys_fast_slot_ref, scm_sys_fast_slot_set_x,
1698 scm_m_atdispatch): Provide FUNC_NAME definition. Don't use
1699 deprecated SCM_OUTOFRANGE macro.
1700
1701 (scm_sloppy_num2ulong, scm_sys_logand): Removed. Guile's logand
1702 function now provides the desired behaviour.
1703
1704 * goops.c (filter_cpl, remove_duplicate_slots), goops.h
1705 (SCM_SUBCLASSP): Don't use deprecated scm_sloppy_memq.
1706
1707 2000-11-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
1708
1709 * symbols.h (SCM_LENGTH_MAX): Deprecated.
1710
1711 * unif.c (scm_make_uve): Use SCM_BITVECTOR_MAX_LENGTH and
1712 SCM_UVECTOR_MAX_LENGTH instead of SCM_LENGTH_MAX. Postpone length
1713 checks for strings and vectors to their constructors. Eliminate
1714 redundant SCM_IMP test.
1715
1716 (scm_dimensions_to_uniform_array): Postpone length checks to
1717 scm_make_uve.
1718
1719 * unif.h (SCM_BITVECTOR_MAX_LENGTH, SCM_UVECTOR_MAX_LENGTH):
1720 Added.
1721

1726 (scm_intern_obarray_soft, scm_sysintern0_no_module_lookup), unif.c
1727 (scm_make_uve), vectors.c (scm_make_vector): Use appropriate
1728 SCM_SET_<type>_(CHARS|BASE) macro instead of SCM_SETCHARS.

1740 free memory for empty bitvectors.
1741
1742 * gh_data.c (makvect), strings.c (scm_makstr, scm_take_str),
1743 symbols.c (scm_intern_obarray_soft,
1744 scm_sysintern0_no_module_lookup), unif.c (scm_make_uve): Use
1745 appropriate SCM_SET_<type>_LENGTH macro instead of SCM_SETLENGTH.

1757
1758 * continuations.h (SCM_SET_CONTINUATION_LENGTH): Added.
1759
1760 2000-11-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
1761
1762 * vectors.c (scm_make_vector), weaks.c (scm_make_weak_vector):

1782 (scm_make_struct_layout), symbols.c (scm_string_to_symbol,
1783 scm_string_to_obarray_symbol, scm_gensym, scm_gentemp): Replace
1784 calls to SCM_ROU?CHARS with the corresponding call to
1785 SCM_STRING_U?CHARS.
1786
1787 * symbols.h (SCM_ROCHARS, SCM_ROUCHARS): Deprecated.
1788
1789 2000-11-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
1790
1791 * ports.c: Include eval.h.
1792
1793 * strings.c (scm_string_set_x), strings.h (SCM_RWSTRINGP),
1794 validate.h (SCM_VALIDATE_RWSTRING): Deprecate SCM_RWSTRINGP and
1795 SCM_VALIDATE_RWSTRING.
1796
1797 * strings.h (SCM_STRING_UCHARS, SCM_STRING_CHARS): Handle strings
1798 and substrings uniformly. However, substring handling is
1799 deprecated.
1800
1801 (SCM_RWSTRINGP): Deprecated.
1802
1803 2000-11-18 Gary Houston <ghouston@arglist.com>
1804
1805 * Makefile.am (.c.x): don't prefix ".:" to $PATH when running
1806 guile-doc-snarf. it doesn't seem to do anything useful, but would
1807 fail if $PATH contained whitespace. Thanks to Lars J. Aas.
1808
1809 2000-11-17 Marius Vollmer <mvo@zagadka.ping.de>
1810
1811 * alist.c, arbiters.c, async.c, backtrace.c, boolean.c, chars.c,

1822 tag.c, threads.c, throw.c, unif.c, variable.c, vectors.c,
1823 version.c, vports.c, weaks.c: Makes sure the snarfer output
1824 inclusion is disabled when the snarfer is run on the file. Thanks
1825 to Lars J. Aas!
1826
1827 * Makefile.am: Install guile-procedures.txt in version-specific
1828 directory to enable multiple installed guile versions. Suggested
1829 by Karl M. Hegbloom <karlheg@debian.org, patch by Matthias Koeppe.
1830
1831 2000-11-13 Gary Houston <ghouston@arglist.com>
1832
1833 * fports.c: include gc.h.
1834 (fport_flush, fport_close): silently ignore I/O errors when
1835 closing a port during gc. it's better than aborting in scm_error.
1836
1837 * throw.c (scm_handle_by_message): remove obsolete comment.
1838
1839 2000-11-12 Gary Houston <ghouston@arglist.com>
1840

1848
1849 2000-11-07 Gary Houston <ghouston@arglist.com>
1850
1851 * ports.c (scm_port_for_each): new proc. implements port-for-each,
1852 which applies a procedure to each port in the port table.
1853 ports.h: declare scm_port_for_each.
1854
1855 * ioext.c (scm_dup2): new proc. implements "dup2" which is a simple
1856 wrapper for the dup2 system call (unlike dup->fdes or
1857 primitive-move->fdes).
1858 * ioext.h: declare scm_dup2.
1859
1860 * filesys.c (scm_close_fdes): new proc. implements "close-fdes"
1861 which is a simple wrapper for close system call (unlike scm_close).
1862 * filesys.h: declare for scm_close_fdes.
1863
1864 2000-11-06 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
1865
1866 * eval.c (SCM_IM_DISPATCH), objects.c (scm_mcache_lookup_cmethod):
1867 Count n_specialized + 1 turns before letting a match through.
1868
1869 * goops.c (scm_sys_invalidate_method_cache_x): Don't convert
1870 scm_si_n_specialized from fixnum and don't take absolute value.
1871 (Thanks to Lars J. Aas.)
1872
1873 2000-11-04 Gary Houston <ghouston@arglist.com>
1874
1875 * ports.c (scm_port_p): new function, implements "port?" which
1876 is mentioned in R5RS.
1877 * ports.h: declare scm_port_p.
1878
1879 2000-11-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
1880
1881 * backtrace.c (display_expression, display_error_body), fports.c
1882 (prinfport), print.c (scm_iprin1): Test for symbols and strings
1883 explicitly instead of using SCM_ROSTRINGP.
1884
1885 * backtrace.c (scm_display_error_message): Don't pass a symbol to
1886 scm_simple_format. Prefer high-level output functions.
1887
1888 (display_error_body): When displaying procedure names, give
1889 preference to the name passed as a parameter. Only if none is
1890 given extract a name from the stack information.
1891
1892 * fports.c (scm_fdes_to_port, prinfport), gc.c (scm_gc_mark),
1893 ports.c (scm_port_filename, scm_set_port_filename_x): Use
1894 SCM_(SET_)?FILENAME.
1895
1896 * gh_data.c (gh_set_substr, gh_scm2newstr, gh_get_substr,
1897 gh_symbol2newstr): Use scm_remember instead of a pair of calls to
1898 scm_protect/unprotect_object.
1899
1900 * goops.c (make_struct_class), objects.c (scm_class_of): Struct
1901 table names are symbols.
1902
1903 * ports.h (SCM_SET_FILENAME): Added.
1904
1905 * print.c (scm_iprin1): Don't use scm_puts to write symbols or
1906 strings in order to treat substrings right. Reposition call to
1907 scm_remember after the last use of object's data.
1908
1909 (scm_simple_format): Treat messages that are substrings right.
1910
1911 * symbols.h (SCM_ROSTRINGP): Deprecated.
1912
1913 2000-11-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
1914
1915 * environments.c (obarray_replace, obarray_retrieve,
1916 obarray_remove): Don't use '==' to compare SCM objects.
1917
1918 * posix.c (scm_getgroups): Don't create a redundant string.
1919
1920 2000-11-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
1921
1922 * symbols.c (scm_sym2vcell, scm_sym2ovcell_soft,
1923 scm_intern_symbol, scm_unintern_symbol): Symbol objects already
1924 hold their hash values, no need to recompute them.
1925
1926 (scm_intern_obarray_soft): Speed up search for a matching symbol
1927 by comparing the hash values first.
1928
1929 2000-10-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
1930
1931 * unif.c (scm_make_uve, scm_dimensions_to_uniform_array): Don't
1932 allow vectors longer than SCM_LENGTH_MAX. This removes the
1933 SCM_HUGE_LENGTH trick, i. e. storing a vector length greater than
1934 SCM_LENGTH_MAX at the beginning of the vector's memory. Since not
1935 all of guile's code was implemented to be aware of this trick, it
1936 is unlikely that it was used anyway. We can implement such a
1937 feature more cleanly by using double cells for uniform vector
1938 types.
1939
1940 (scm_shap2ra): Replace SCM_IMP and SCM_NIMP tests by more
1941 straightforward predicates.
1942
1943 (scm_dimensions_to_uniform_array): Require that for dimensions
1944 given as lower-bound/upper-bound pairs the upper-bound is never
1945 less than the lower bound.

1966 strports.c (scm_mkstrport), symbols.c
1967 (scm_string_to_obarray_symbol), vports.c (scm_make_soft_port):
1968 Don't accept symbols as input parameters. Use SCM_STRING_LENGTH
1969 instead of SCM_ROLENGTH.
1970
1971 * dynl.c (scm_dynamic_link, scm_dynamic_func), error.c
1972 (scm_error_scm), filesys.c (scm_chown, scm_chmod, scm_open_fdes,
1973 scm_stat, scm_link, scm_rename, scm_delete_file, scm_mkdir,

1982 (setzone, scm_strftime, scm_strptime), vports.c
1983 (scm_make_soft_port): Use SCM_STRING_COERCE_0TERMINATION_X to
1984 make sure the characters of a string are followed by a \0.
1985 Further, use SCM_STRING_CHARS instead of SCM_ROCHARS on the
1986 resulting string.
1987
1988 * dynl.c (scm_make_argv_from_stringlist), posix.c
1989 (scm_convert_exec_args): Aligned to match each other.
1990
1991 * dynl.c (scm_coerce_rostring): Removed.
1992
1993 (scm_dynamic_func): Changed the comment to reflect that the
1994 function name has to be a string. Further, hide implementation
1995 details from the scheme comment.
1996
1997 * error (scm_error_scm): Don't accept a symbol as message
1998 parameter. Fix substring handling.
1999
2000 * posix.c (environ_list_to_c): Use memcpy to copy environment
2001 strings. Handle substrings which don't have a trailing \0.
2002
2003 * symbols.h (SCM_LENGTH, SCM_ROLENGTH, SCM_SUBSTRP,
2004 SCM_SUBSTR_STR, SCM_SUBSTR_OFFSET, SCM_COERCE_SUBSTR):

2013
2014 * random.c: Include unif.h.
2015
2016 * strings.h (SCM_STRING_COERCE_0TERMINATION_X): Added. This is
2017 intended to replace the macro SCM_COERCE_SUBSTR. Such a macro
2018 will be necessary, even after copy-on-write strings will be added
2019 to guile, but the current naming is inappropriate.
2020
2021 * strorder.c (scm_string_equal_p, scm_string_ci_equal_p,
2022 scm_string_less_p, scm_string_ci_less_p): Don't accept symbols as
2023 input parameters. Further, the functions that test for equality
2024 are rewritten to compare from back to front, the others are also a

2029 This change merges the GOOPS code into Guile. However, GOOPS
2030 is still not initialized until someone asks for the module.
2031 We need to optimize GOOPS initialization time before initializing
2032 it together with the rest of libguile. We also need to add the
2033 C API + primitive methods. Then we can start using it to
2034 modularize Guile, implement a real exception system etc.
2035
2036 * goops.c, objects.c, objects.h, eval.c (scm_make_extended_class,
2037 scm_make_port_classes, scm_change_object_class,

2055 function.
2056 Added #include "libguile/goops.h".

2108 anyway.)
2109
2110 * simpos.c (scm_system): Fix condition.

2112 * strings.c (scm_string_length, scm_string_ref, scm_substring,

2439 scm_struct_set_x): Use SCM_STRING_U?CHARS or SCM_SYMBOL_U?CHARS
2440 instead of SCM_U?CHARS.

2456
2457 2000-09-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
2458
2459 * gc.c (scm_gc_mark, scm_gc_sweep), tags.h: Removed the
2460 scm_tc7_lvector type tag.
2461

2463
2464 * eval.c (scm_m_define), evalext.c (scm_m_undefine): Removed dead
2465 code.
2466
2467 * gc.c (scm_gc_sweep): Use SCM_STRING_CHARS or SCM_SYMBOL_CHARS

2471
2472 * backtrace.c (display_frame_expr), environments.c

2486 2000-09-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
2487
2488 * strings.h (SCM_STRING_CHARS): Added, should be used instead of
2489 SCM_CHARS whenever the argument is known to be a string.
2490
2491 (SCM_SLOPPY_STRINGP): Deprecated.
2492
2493 * symbols.h (SCM_SYMBOL_CHARS): Added, should be used instead of
2494 SCM_CHARS whenever the argument is known to be a symbol.
2495
2496 2000-09-22 Neil Jerram <neil@ossau.uklinux.net>
2497
2498 * struct.c (scm_make_struct): Fix texinfo warning in docstring by
2499 using @pxref rather than @xref.
2500
2501 * root.c (scm_call_with_dynamic_root): Fix texinfo warning in
2502 docstring by using @code for (thunk) rather than @var.
2503
2504 2000-09-20 Marius Vollmer <mvo@zagadka.ping.de>
2505
2506 * numbers.c (scm_istr2flo): Throw an `out of range' error when
2507 exponent is too large instead of returning `#f'. The rationale is
2508 that in this case the string represents a valid number but we
2509 can't deal with it.
2510
2511 2000-09-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2512
2513 * symbols.c (scm_intern_obarray_soft,
2514 scm_sysintern0_no_module_lookup): Make sure that symbol

2519
2520 * throw.c (scm_handle_by_message): Added a FIXME comment.

2523 gcc, always add the GCSE bug workaround.
2524
2525 2000-09-14 Gary Houston <ghouston@arglist.com>
2526
2527 * print.c (scm_iprin1): write the ascii delete character as #\del
2528 instead of '#\', so it can be read back. like in SCM.
2529
2530 2000-09-12 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
2531
2532 * symbols.c (duplicate_string): Don't try to copy the byte after
2533 the string. This might not be `\0' and might even not be
2534 allocated memory.
2535
2536 2000-09-12 Dirk Herrmann <D.Herrmann@tu-bs.de>
2537
2538 * symbols.c (scm_symbol_p): Eliminate redundant SCM_IMP test.
2539
2540 2000-09-12 Dirk Herrmann <D.Herrmann@tu-bs.de>
2541
2542 This patch unifies the formerly distinct ssymbol and msymbol types
2543 to a common symbol type scm_tc7_symbol. The representation of the
2544 new symbol type uses a double cell with the following layout:
2545 <type/length, chars, raw_hash, prop-pair>, where the car of
2546 prop-pair holds the symbol's function property and the cdr of
2547 prop-pair holds the symbol's other properties. In the long run,
2548 these properties will be removed. Then, the generic property
2549 functions will be uses.
2550
2551 * eval.c (SCM_CEVAL), objects.c (scm_class_of), print.c
2552 (scm_iprin1), tag.c (scm_tag): Use scm_tc7_symbol instead of
2553 scm_tc7_ssymbol, scm_tc7_msymbol or scm_tcs_symbols.
2554
2555 * gc.c (scm_gc_mark): Mark the symbols property pair.
2556
2557 (scm_gc_sweep): There are no symbol slots any more.
2558
2559 * hash.c (scm_hasher): Instead of re-calculating the hash value
2560 of a symbol, use the raw_hash value stored in the symbol itself.
2561
2562 * properties.h: Fix typo.
2563
2564 * strings.[ch] (scm_makstr, scm_makfromstr): The slot parameter
2565 is not used any more.
2566
2567 * symbols.[ch] (scm_strhash): Deprecated, replaced by a macro.
2568
2569 (scm_intern_obarray_soft): Made softness parameter unsigned.
2570
2571 (scm_string_hash): New function with the same functionality as
2572 scm_strhash had before, except that the hash value is not adjusted
2573 to a hash table size. Instead, the 'raw' hash value is returned.
2574
2575 * symbols.c (duplicate_string): New static convenience function.
2576
2577 (scm_sym2vcell, scm_sym2ovcell_soft, scm_intern_obarray_soft):
2578 Renamed local variable from scm_hash to hash.
2579
2580 (scm_intern_obarray_soft): Don't check for a negative softness
2581 any more. When generating symbol cells, use the new layout and
2582 store the raw hash value in the symbol's cell.
2583
2584 (scm_symbol_to_string): Removed unnecessary cast.
2585
2586 (scm_intern_symbol, scm_unintern_symbol): Use scm_string_hash to
2587 determine the hash values.
2588
2589 (msymbolize): Removed.
2590
2591 (scm_symbol_fref, scm_symbol_pref, scm_symbol_fset_x,
2592 scm_symbol_pset_x, scm_symbol_hash): No need to distinguish
2593 between different symbol types any more.
2594
2595 (scm_symbol_hash): Comment fixed.
2596
2597 * symbols.h: Comment about the distinction between ssymbols and
2598 msymbols removed.
2599
2600 (SCM_SYMBOLP, SCM_ROSTRINGP): No need to distinguish between
2601 different symbol types any more.
2602
2603 (SCM_PROP_SLOTS, SCM_SET_PROP_SLOTS): Added.
2604
2605 (SCM_SYMBOL_FUNC, SCM_SET_SYMBOL_FUNC, SCM_SYMBOL_PROPS,
2606 SCM_SET_SYMBOL_PROPS, SCM_SYMBOL_HASH, SCM_SET_SYMBOL_HASH): Use
2607 the new symbol cell layout.
2608
2609 * tags.h (scm_tc7_ssymbol, scm_tc7_msymbol, scm_tcs_symbols):
2610 Deprecated.
2611

2613
2614 * symbols.h (scm_gentemp): Declared.
2615
2616 * symbols.c (scm_gensym): Reimplemented. Now only takes one
2617 optional argument which should be a *string*.
2618 (scm_gentemp): Reimplemented and moved from boot-9.scm.
2619
2620 2000-09-10 Keisuke Nishida <kxn30@po.cwru.edu>
2621
2622 * modules.c: Use applicable smobs for eval closures instead of
2623 compiled closures. Include "libguile/smob.h".
2624 (f_eval_closure): Removed.
2625 (scm_eval_closure_tag): New variable.
2626 (scm_eval_closure_lookup): Renamed from eval_closure.
2627 This function now takes a smob instead of a compiled closure.
2628 (scm_standard_eval_closure): Create a smob instead of a compiled
2629 closure.
2630 (scm_init_modules): Initialize the eval closure type as a smob.
2631 * modules.h (SCM_EVAL_CLOSURE_P): New macro.
2632 (scm_eval_closure_tag, scm_eval_closure_lookup): Declare.
2633 * symbols.c: Include "libguile/smob.h".
2634 (scm_sym2vcell): Call scm_eval_closure_lookup directly if THUNK
2635 is an eval closure.
2636
2637 2000-09-10 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
2638
2639 * Makefile.am (.x.doc): Bugfix: Added $(srcdir) to path in order
2640 to allow for builds in separate tree.
2641
2642 * symbols.c (scm_gensym): Bugfixed my previous bugfix. (Thanks to
2643 Dale P. Smith.)
2644
2645 2000-09-10 Keisuke Nishida <kxn30@po.cwru.edu>
2646
2647 * eval.c (SCM_APPLY): Fixed bugs in the applicable-smob calls.
2648
2649 2000-09-07 Dirk Herrmann <D.Herrmann@tu-bs.de>
2650
2651 * environments.c (obarray_enter, obarray_retrieve,
2652 obarray_remove): Make sure the hash value is a valid obarray
2653 index.
2654
2655 (obarray_enter, obarray_remove): Documentation improved.
2656
2657 (obarray_replace): Added.
2658
2659 (leaf_environment_define, leaf_environment_undefine): Cleaned up
2660 and optimized.
2661
2662 2000-09-05 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
2663
2664 * symbols.c (scm_gensym): Check that argument is a symbol, not a
2665 string. (Thanks to Ralf Mattes.)
2666
2667 2000-09-05 Marius Vollmer <mvo@zagadka.ping.de>
2668
2669 * init.c: Include "libguile/properties.h".
2670
2671 * gh_data.c (gh_scm2char): Validate that argument is a character.
2672
2673 2000-08-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2674
2675 * environments.h (SCM_IMPORT_ENVIRONMENT_P,
2676 SCM_EXPORT_ENVIRONMENT_P): Before fetching the environment
2677 functions, make sure that we really got an environment.
2678
2679 2000-09-03 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
2680
2681 * validate.h (SCM_VALIDATE_NUMBER_DEF_COPY): New macro.
2682
2683 2000-09-03 Marius Vollmer <mvo@zagadka.ping.de>
2684
2685 * Makefile.am (.x.doc): Pretend to create .doc files from .x files
2686 and give explicit dependencies for .x files that depend on
2687 generated files. This allows parallel builds. Thanks to Matthias
2688 Koeppe!
2689
2690 2000-08-27 Marius Vollmer <mvo@zagadka.ping.de>
2691
2692 * Makefile.am: Added gc_os_dep.c, properties.c, properties.x,
2693 properties.h and properties.doc in the suitable places.
2694
2695 * init.h (scm_init_guile): New prototype.
2696
2697 * init.c (scm_init_guile, scm_init_guile_1): New interface for
2698 initializing Guile that does return to the caller.
2699 (scm_boot_guile_1): Use scm_init_guile_1 to initialize Guile.
2700 Do not establish a catch-all, this is no longer needed.
2701
2702 * root.h (scm_properties_whash): New `sys_protect', used in
2703 properties.c.
2704
2705 * throw.c (scm_ithrow): Perform catch-all handling here when no
2706 suitable handler has been found. That way, we don't have to rely
2707 on the user establishing a catch-all, which might be difficult for
2708 him if he is using scm_init_guile instead of scm_boot_guile.
2709
2710 2000-09-03 Neil Jerram <neil@ossau.uklinux.net>
2711

2736
2737 * socket.c (scm_recvfrom): Docstring format fix: missing newline
2738 inserted.
2739
2740 * ramap.c (scm_array_copy_x): Docstring: add @deffnx line for
2741 array-copy-in-order!.

2754
2755 the following changes let Guile get rid of the `allocated' cell
2756 state.
2757
2758 * smob.c (scm_smob_prehistory): don't init the "allocated" smob
2759 type.
2760
2761 * tags.h (scm_tc16_allocated): removed.
2762
2763 * gc.h: removed now-obsolete comments about the `allocated' cell
2764 state.
2765 (SCM_NEWCELL): don't change cell type to `allocated'.
2766 (SCM_NEWCELL2): ditto.
2767
2768 * gc.c (scm_mark_locations): mark freecells too, and don't worry
2769 about any possible false positives.
2770 (scm_debug_newcell): don't change cell type to `allocated'.
2771 (scm_debug_newcell2): ditto.
2772 (scm_gc_for_newcell): ditto.
2773 (scm_gc_mark): remove the tc16_allocated case.
2774
2775 2000-08-26 Mikael Djurfeldt <mdj@linnaeus.mit.edu>

2777 * gdbint.c (gdb_print): Removed superfluous macro definition.
2778
2779 * objects.c (scm_init_objects), print.c (scm_init_print), struct.c
2780 (scm_init_struct): First arg to scm_make_vtable_vtable should be a
2781 string, not a symbol. (`make-vtable-vtable' needs to append this
2782 string to another string and then pass it through
2783 `make-struct-layout'.)
2784
2785 * stacks.c (scm_init_stacks): Pass a string, not a layout object,
2786 to scm_make_vtable_vtable. (Thanks to Dale P. Smith.)
2787
2788 * struct.c (scm_make_struct_layout): Removed reference to
2789 "read-only string" in comment; Check that argument is a string.
2790 (scm_make_vtable_vtable): Check that argument is a string.
2791
2792 * environments.c (scm_init_environments): All internal includes in
2793 libguile must use the prefix "libguile/" in path names since inly
2794 the top-level source directory is on the include list. (That, in
2795 turn, is because we want to distinguish between system header
2796 files and hedares files internal to libguile.)
2797
2798 * strings.c (scm_make_shared_substring, scm_read_only_string_p):
2799 Deprecated.
2800 (scm_string_length, scm_string_ref, scm_substring,
2801 scm_string_append): Don't accept symbols as arguments (R5RS).
2802
2803 2000-08-25 Neil Jerram <neil@ossau.uklinux.net>
2804
2805 * ports.c (scm_set_port_column_x): Fix docstring so that it
2806 mentions set-port-line! rather than set-port-column! twice.
2807
2808 * guardians.c (scm_make_guardian): Remove spurious . from doc string.
2809
2810 2000-08-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2811
2812 * Makefile.am: Added all necessary environments.* files.
2813
2814 * init.c: Include environments.h.
2815
2816 (scm_boot_guile_1): Initialize the environments.
2817
2818 * environments.[ch]: Added. Most of the credit for these files
2819 goes to Jost Boekemeier.
2820
2821 2000-08-25 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
2822
2823 * procprop.c: #include "libguile/smob.h"; handle applicable smobs.
2824
2825 2000-08-24 Keisuke Nishida <kxn30@po.cwru.edu>
2826
2827 * smob.h (scm_smob_descriptor): Added `apply' and `gsubr_type'.
2828 * smob.c (scm_make_smob_type): Initialize `apply' and `gsubr_type'.
2829 (scm_set_smob_apply): New function.
2830 (scm_smob_apply_0, scm_smob_apply_1, scm_smob_apply_2,
2831 scm_smob_apply_3): New functions.
2832 * eval.c (SCM_CEVAL, SCM_APPLY): Added dispatch for applicable smobs.

2834
2835 2000-08-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2836
2837 * Makefile.am (BUILT_SOURCES): Experimentally added scmconfig.h
2838 also here. (This is supposed to make sure that scmconfig.h is
2839 built before all sources in order to prevent that everything has
2840 to be rebuilt again. Hope it works---I'm just guessing. :)
2841
2842 * fluids.c (scm_fluid_set_x): Return SCM_UNSPECIFIED.
2843
2844 2000-08-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2845
2846 * gc.c (scm_gc_mark): Don't use GUILE_DEBUG flag to compile in
2847 extra tests. (GUILE_DEBUG is only supposed to make extra
2848 debugging functions available.)
2849
2850 2000-08-21 Michael Livshin <mlivshin@bigfoot.com>
2851
2852 * gc.h (SCM_GC_CARD_N_CELLS): change to be a nice non-confusing
2853 constant.
2854
2855 2000-08-19 Michael Livshin <mlivshin@bigfoot.com>
2856
2857 * gc.c (scm_gc_sweep): added a `continue' statement that have
2858 fallen through the cracks in the merge. thanks to Shuji Narazaki!
2859
2860 * gc.h: removed some stuff that broke compilation for people and
2861 wasn't actually needed anyway.
2862
2863 2000-08-18 Neil Jerram <neil@ossau.uklinux.net>
2864
2865 * filesys.c (scm_fcntl): Docstring fix - missing newlines inserted.
2866
2867 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_sethost,
2868 scm_setnet, setproto, setserv): Argument names changed to match
2869 doc string.
2870
2871 * feature.c (scm_program_arguments): New docstring.
2872
2873 * simpos.c (scm_getenv): Reflow docstring.
2874
2875 * eq.c (scm_eq_p, scm_eqv_p, scm_equal_p): Add texinfo markup to
2876 docstrings.
2877
2878 * chars.c (scm_char*): Docstring fixes - texinfo markup.
2879
2880 2000-08-18 Neil Jerram <neil@ossau.uklinux.net>
2881
2882 * boolean.c (scm_not, scm_boolean_p): Docstring fixes - add
2883 texinfo markup and remove trailing newlines.
2884
2885 2000-08-17 Michael Livshin <mlivshin@bigfoot.com>
2886
2887 this changes the Guile GC to use cards (aka "chunklets").
2888 (most of the ideas and some of the code are by Greg Harvey, though
2889 the code is probably unrecognizable now. the original chunklet
2890 proposal, way back, is by Dale Jordan).
2891
2892 * tags.h: (SCM_GCTYPE16, SCM_GCCDR, SCM_GC[8]MARKP,
2893 SCM_SETGC[8]MARK, SCM_CLRGC[8]MARK): moved from here into gc.h.
2894 some (most) of these are probably going to be deprecated.
2895
2896 * gc.h (SCM_MARKEDP): simplified, there are no different mark bit
2897 locations anymore.
2898 (SCM_GC_CARD_*, SCM_C_BVEC_*): lots of new macros to deal with
2899 cards and bvecs (bit-vectors).
2900
2901 * gc.c: (scm_default_init_heap_size_*): defined to take cards into
2902 account, but keeping more or less the same values as previously.
2903 added some simple helper macros.
2904 (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK): defined to take cards
2905 into account.
2906 (BVEC_*, scm_mark_space_t, current_mark_space, mark_space_ptr,
2907 current_mark_space_offset, mark_space_head, get_bvec,
2908 clear_mark_space): new functions and supporting variables, types
2909 and macros that implement mark space management.
2910 (scm_igc): clear the mark space (all of it) before beginning the
2911 mark phase.
2912 (scm_gc_mark): changed the tests for rogue cells, much simplified
2913 throughout (no different mark bit locations to worry about now).
2914 (scm_mark_locations): don't consider card header cells.
2915 (scm_cellp): ditto.
2916 (scm_gc_sweep): simplified.
2917 (init_heap_seg): changed to take cards into account.
2918
2919 2000-08-16 Michael Livshin <mlivshin@bigfoot.com>
2920
2921 * stime.c (scm_c_get_internal_run_time): new function, same as
2922 scm_get_internal_run_time but returns a long. it's used by the GC
2923 for timekeeping, since with scm_get_internal_run_time there is a
2924 (extremely theoretical) possibility of consing.
2925 (scm_get_internal_run_time): redefined in terms of
2926 scm_c_get_internal_run_time.
2927
2928 * stime.h: added prototype for scm_c_get_internal_run_time.
2929
2930 * gc.c (scm_gc_stats): add more obscure stats, such as: mark time,
2931 sweep time, total marked cells, total swept cells, and number of
2932 times GC was invoked.
2933 (gc_start_stats): renamed from scm_gc_start, made static, taught
2934 to init the new stats.
2935 (gc_end_stats): renamed from scm_gc_end, made static, taught to
2936 calculate the new stats.
2937 (scm_igc): don't call gc_start_stats unless we are sure that we
2938 are indeed going to collect. also, added some timekeeping between
2939 the mark and sweep phases.
2940 (scm_gc_sweep): count number of cells we sweep as we go.
2941
2942 * gc.h: removed prototypes for scm_gc_{start,end}.
2943
2944 2000-08-13 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
2945
2946 * alist.c (scm_assq, scm_assv, scm_assoc): Report argument type
2947 error for the alist rather than the sublist where the type
2948 mismatch is discovered.
2949
2950 2000-08-13 Neil Jerram <neil@ossau.uklinux.net>
2951
2952 * root.c (s_scm_call_with_dynamic_root): Docstring fix - rogue
2953 newline.
2954
2955 2000-08-12 Neil Jerram <neil@ossau.uklinux.net>

2958
2959 * ports.c (scm_port_filename): Docstring fix - missing newline.
2960
2961 * strports.c (scm_eval_string): Docstring fix - missing newline.
2962
2963 * vports.c (s_scm_make_soft_port): Docstring updated so that
2964 example is correct.
2965
2966 * strop.c: Docstring fixes - quotation marks and backslashes
2967 needed quoting.
2968
2969 * numbers.c (s_scm_logand): Docstring fix - "@end lisp" inserted.
2970
2971 2000-08-11 Neil Jerram <neil@ossau.uklinux.net>
2972
2973 * macros.c: Remove surplus newlines from end of docstrings.
2974
2975 * list.c (scm_list_tail): Add @deffnx line to docstring for
2976 list-cdr-ref.
2977
2978 * keywords.c: Docstring improvements in conjunction with new
2979 reference manual doc on keywords.
2980
2981 * error.c (scm_error_scm): Fix texinfo syntax error in

2984 * dynl.c: Remove surplus newlines from end of docstrings.
2985
2986 2000-08-11 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
2987
2988 * eval.c (scm_eval): Backward incompatible change: Now takes an
2989 environment specifier as second arg. `eval' hereby becomes R5RS
2990 compatible.
2991 (scm_i_eval_x, scm_i_eval): New functions (replace
2992 scm_eval_3).
2993 (scm_eval2, scm_eval_3): Deprecated.
2994 (scm_top_level_lookup_closure_var): Deprecated.
2995
2996 * eval.h: #include "struct.h".
2997
2998 * evalext.c (scm_definedp): Have to work before module system is
2999 booted.
3000
3001 * modules.h (SCM_MODULEP, SCM_VALIDATE_MODULE,

3003 SCM_MODULE_EVAL_CLOSURE): New macros.
3004 (scm_module_index_obarray, scm_module_index_uses,
3005 scm_module_index_binder, scm_module_index_eval_closure): New
3006 constants; #include "validate.h".
3007

3019 * script.c (scm_shell): Pass scm_the_root_module () as second arg
3020 to new scm_eval_x.
3021
3022 * load.c (load): Use `scm_selected_module' to compute second arg
3023 to new scm_i_eval_x; Don't call it if module system hasn't booted.
3024 (scm_read_and_eval_x): Deprecated.
3025 #include "modules.h".
3026
3027 * debug.c (scm_local_eval): Use scm_i_eval and scm_i_eval_x.
3028 (scm_start_stack): Use scm_i_eval.
3029
3030 * strports.c: #include "modules.h".
3031
3032 * print.c (scm_simple_format): Be case-insensitive for ~A and ~S
3033 directives.
3034
3035 2000-08-09 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
3036
3037 The following changes are intended to ensure that struct instances
3038 are freed before their vtables. It's optimized for the most
3039 common case, which is freeing of struct instances.
3040
3041 * gc.c (scm_gc_mark, scm_gc_sweep): Remove vcell = 1 magic.
3042 (scm_structs_to_free): New variable.
3043 (scm_gc_sweep): Hook up structs to free on the scm_structs_to_free
3044 chain.
3045
3046 * struct.h (SCM_STRUCT_GC_CHAIN, SCM_SET_STRUCT_GC_CHAIN): New
3047 macros.
3048 (scm_structs_to_free, scm_struct_prehistory): Declare.
3049
3050 * struct.c (scm_make_struct, scm_make_vtable_vtable): Structs
3051 handles are now double cells; Initialize SCM_STRUCT_GC_CHAIN to
3052 0.
3053 (scm_struct_gc_init, scm_free_structs): New GC C hooks.
3054 (scm_struct_prehistory): Install them.
3055
3056 * init.c (scm_boot_guile_1): Call scm_struct_prehistory.
3057
3058 2000-08-06 Marius Vollmer <mvo@zagadka.ping.de>
3059
3060 * read.c (scm_flush_ws): Include filename in error message when it
3061 is not `#f'.
3062
3063 2000-08-05 Marius Vollmer <mvo@zagadka.ping.de>
3064
3065 * iselect.c: Include <unistd.h>. Thanks to Bertrand Petit!
3066
3067 2000-08-02 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
3068
3069 * struct.c (scm_make_struct_layout, scm_make_struct,
3070 scm_make_vtable_vtable): Updated documentation.
3071
3072 * print.c (scm_simple_format): Bugfix: Coerce port before using
3073 it.
3074
3075 2000-07-31 Gary Houston <ghouston@arglist.com>
3076
3077 * net_db.c: declare h_errno only if HAVE_H_ERRNO is not defined
3078 (thanks to Richard Kim for the bug report).
3079
3080 2000-07-30 Marius Vollmer <mvo@zagadka.ping.de>
3081
3082 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
3083 scm_assoc_remove_x): Use scm_delq1_x instead of scm_delq_x, since
3084 using the latter is pointless.
3085
3086 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
3087
3088 * gc.c (scm_gc_sweep): Renamed local variable from 'free' to
3089 'free_struct_data' to avoid confusion with stdlib's 'free'.
3090
3091 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
3092
3093 * vectors.c (scm_make_vector): Fix the initialization order of
3094 the vector such that the type cell is initialized last.
3095
3096 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
3097
3098 * struct.[ch] (scm_struct_init): Made static. Fixed not to rely
3099 on the struct cell to be fully initialized.
3100
3101 * struct.c (scm_make_struct, scm_make_vtable_vtable): Fix the
3102 initialization order of the struct such that the type cell is
3103 initialized last.
3104
3105 2000-07-25 Marius Vollmer <mvo@zagadka.ping.de>
3106
3107 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
3108 scm_assoc_remove_x): Remove only the first cell with a matching
3109 key, not all.
3110
3111 2000-07-24 Marius Vollmer <mvo@zagadka.ping.de>
3112
3113 * stime.c (scm_strftime): Recognize a return value of zero from
3114 strftime as buffer overflow and take care to detect a valid zero
3115 length result regardless. Thanks to David Barts!
3116
3117 2000-07-23 Marius Vollmer <mvo@zagadka.ping.de>
3118
3119 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
3120 scm_assoc_remove_x): Remove all cells whose key is eq, eqv, or
3121 equal (respectively) to the argument key, not all cells that are
3122 eq, eqv, or equal to the first cell with the argument key. Thanks
3123 to Neil Jerram!
3124
3125 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
3126
3127 * gc.h (SCM_FREE_CELL_CDR, SCM_SET_FREE_CELL_CDR), hooks.c
3128 (make_hook), modules.c (OBARRAY, USES, BINDER): Pack and unpack
3129 SCM values appropriately.
3130
3131 * modules.c (scm_standard_eval_closure): Don't pass an inum to
3132 scm_makcclo, but rather a long value.
3133
3134 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
3135
3136 read.c (scm_lreadrecparen), srcprop.c (scm_set_source_property_x):
3137 SCM_SETCDR and SCM_WHASHSET macros don't deliver a return value.
3138 Thanks to Han-Wen Nienhuys for the bug report.
3139
3140 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
3141
3142 * root.[ch] (scm_call_catching_errors): Deprecated.
3143
3144 * root.c (scm_init_root): Initialize the root smob type using the
3145 standard initialization functions.
3146
3147 2000-07-17 Marius Vollmer <mvo@zagadka.ping.de>
3148
3149 * eval.c (unmemocopy): Don't rely on V being a list of at least
3150 one element. Thanks to Bill Schottstaedt!
3151
3152 2000-07-15 Michael Livshin <mlivshin@bigfoot.com>
3153
3154 * gc.c (scm_done_free): new.
3155 expanded comments about scm_done_malloc.
3156
3157 * gc.h: added prototype for scm_done_free
3158
3159 2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
3160
3161 * gc.h (scm_take_stdin): Removed.
3162
3163 * gc.h (SCM_VALIDATE_CELL): Delegate cell checks to function
3164 scm_assert_cell_valid to allow extensions to the checking
3165 functionality without need to recompile everything.
3166
3167 * gc.[ch] (scm_assert_cell_valid, scm_set_debug_cell_accesses_x):
3168 Added as conditionally compiled functions for the case that
3169 SCM_DEBUG_CELL_ACCESSES is enabled.
3170
3171 * gc.c (debug_cells_p): Added to indicate whether compile-time
3172 included cell access debugging is run-time enabled.
3173
3174 * gc.[ch] (scm_gc_running_p): Added to indicate that scm_igc is
3175 being executed. Intended to be used instead of scm_gc_heap_lock
3176 at most places.
3177
3178 * error.c (scm_error), gdbint.c (SCM_GC_P): Use scm_gc_running_p
3179 instead of scm_gc_heap_lock.
3180
3181 * gc.c (scm_igc): Set scm_gc_running_p to true while running.
3182
3183 * gc.c (scm_mark_locations): Don't mark free cells.
3184
3185 * weaks.c (scm_scan_weak_vectors): Use SCM_FREE_CELL_P instead of
3186 SCM_FREEP.
3187
3188 2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
3189
3190 * gc.c (scm_mark_locations): Minimized some variable scopes and
3191 simplified the code a bit.
3192
3193 2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
3194
3195 * gc.h (SCM_SET_FREE_CELL_TYPE, SCM_SET_FREE_CELL_CDR,
3196 SCM_FREE_CELL_P, SCM_FREE_CELL_CDR): Added since free cells
3197 should not be accessed via SCM_C[AD]R. Further, using dedicated
3198 macros to access free cells allows all other cell accessing macros
3199 to treat acesses to free cells as errors, thus enabling better
3200 error checks for cell accesses. SCM_FREE_CELL_P is supposed to
3201 replace SCM_FREEP some time.
3202
3203 * gc.h (SCM_NEWCELL, SCM_NEWCELL2), gc.c (map_free_list,
3204 free_list_length, scm_check_freelist, scm_debug_newcell,
3205 scm_debug_newcell2, freelist_length, scm_gc_for_newcell,
3206 scm_gc_mark, scm_gc_sweep, init_heap_seg): Only use the dedicated
3207 cell accessors when accessing free cells.
3208
3209 2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
3210
3211 * gc.h (SCM_CELL_WORD, SCM_CELL_OBJECT): Treat the referenced
3212 object as const in order to make the compiler warn about code like
3213 SCM_CELL_WORD (x, n) = y. Instead, SCM_SET_CELL_WORD (x, n, y)
3214 should be used.
3215
3216 (SCM_CELL_WORD_LOC, SCM_CARLOC, SCM_CDRLOC): Return the address
3217 as an address to a non-const object, since these macros are used
3218 to allow direct write access to objects.
3219
3220 2000-07-07 Dirk Herrmann <D.Herrmann@tu-bs.de>
3221
3222 * hashtab.c (scm_hash_fn_create_handle_x): Signal an error if the
3223 given hash table has no slots.
3224
3225 2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
3226
3227 * gc.c (policy_on_error): Added in order to allow alloc_some_heap
3228 to react to malloc failures in a context dependent way.
3229
3230 (scm_check_freelist): No need to flush streams before abort().
3231
3232 (scm_gc_for_newcell): Try to allocate new memory in three phases:
3233 grow heap if preferred, if still no memory available collect
3234 garbage, if still no memory available grow heap.
3235
3236 (heap_segment_table_size): Added to always reflect the actual
3237 size of the heap segment table, because scm_n_heap_segs may differ
3238 from the heap segment table size.
3239
3240 (alloc_some_heap): In case of malloc failure, react according to
3241 the new policy_on_error parameter (either return to caller or
3242 abort immediately). Further, keep heap_segment_table_size up to
3243 date.
3244
3245 (scm_init_storage): Initialize heap_segment_table_size.
3246
3247 2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
3248
3249 * gh.h: Don't include <stdio.h>. Thanks to Han-Wen Nienhuys for
3250 the hint.
3251
3252 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
3253
3254 * __scm.h (SCM_OUTOFRANGE, SCM_NALLOC, SCM_HUP_SIGNAL,
3255 SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL, SCM_SEGV_SIGNAL,
3256 SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL, SCM_SIG_ORD,
3257 SCM_ORD_SIG, SCM_NUM_SIGS): Re-introduce these as deprecated
3258 symbols.
3259
3260 * error.c (scm_wta): Re-introduce dispatching for SCM_OUTOFRANGE
3261 and SCM_NALLOC, but as a deprecated feature.
3262
3263 2000-06-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3264
3265 * debug.c: Added #include fluids.h.
3266
3267 * numbers.c (scm_gr_p, scm_leq_p, scm_geq_p): Turned into
3268 primitive generics. (Thanks to Nicolas Neuss.)
3269
3270 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
3271
3272 * gc.c (alloc_some_heap): Use scm_memory_error to indicate a
3273 failed attempt to get additional memory from the system.
3274
3275 (scm_gc_for_newcell): Changed the control structure to make the
3276 behaviour explicit for the case that gc is not able to free any
3277 cells.
3278
3279 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
3280
3281 * __scm.h (SCM_OUTOFRANGE): Removed.
3282
3283 * error.c (scm_wta): Removed sick dispatch code for range
3284 errors. (More sick dispatches still to be removed.)
3285
3286 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
3287 scm_hash_fn_remove_x): Eliminate redundant test for if unsigned
3288 value is non-negative. Use scm_out_of_range to signal range
3289 errors.
3290
3291 * hooks.c (make_hook), unif.c (scm_aind): Use scm_out_of_range to
3292 signal range errors.
3293
3294 * list.c (scm_list_ref, scm_list_set_x, scm_list_cdr_set_x): Fix
3295 error reporting (now uses original input parameter to report wrong
3296 type argument errors). Use SCM_OUT_OF_RANGE to report range
3297 errors and SCM_WRONG_TYPE_ARG to report type errors.
3298
3299 * strings.c (scm_substring): Make range checks for negative
3300 values explicit (former behaviour relied on an implicit
3301 conversion from signed to unsigned). Don't use SCM_ASSERT for
3302 range checks.
3303
3304 * unif.c (scm_aind, scm_transpose_array, scm_bit_set_star_x,
3305 scm_bit_count_star): Use scm_out_of_range to signal range
3306 errors.
3307
3308 * unif.c (scm_transpose_array, scm_bit_position), vectors.c
3309 (scm_vector_ref, scm_vector_set_x, scm_vector_move_left_x,
3310 scm_vector_move_right_x): Use SCM_ASSERT_RANGE to check ranges.
3311
3312 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
3313
3314 * validate.h (SCM_VALIDATE_INUM_MIN_COPY,
3315 SCM_VALIDATE_INUM_MIN_DEF_COPY, SCM_VALIDATE_INUM_RANGE_COPY):
3316 Perform all range checks based on the input value. The former way
3317 of using the value that is assigned to the target variable fails
3318 if the assignment to the target variable itself can change the
3319 value because of type conversion.
3320
3321 (SCM_ASSERT_RANGE): Use scm_out_of_range to signal range errors.
3322
3323 2000-06-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3324
3325 * gc.c (scm_gc_for_newcell): Behave gracefully also if scm_igc
3326 doesn't yield any new cells. In theory this could happen if all
3327 cells allocated with NEWCELL are either in use or conservatively
3328 marked and all cluster spine cells are conservatively marked.
3329 (Thanks to Dirk.)
3330
3331 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
3332
3333 * __scm.h (SCM_NALLOC): Removed.
3334
3335 * error.c (scm_wta): Removed sick dispatch code for memory
3336 errors. (More sick dispatches still to be removed.)
3337
3338 * numbers.c (scm_mkbig, scm_adjbig), ports.c (scm_make_port_type),
3339 random.c (scm_i_copy_rstate, scm_c_make_rstate), smob.c
3340 (scm_make_smob_type), srcprop.c (scm_make_srcprops), vectors.c
3341 (scm_vector_set_length_x): Now using scm_memory_error to signal
3342 memory errors.
3343
3344 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
3345
3346 * __scm.h: Removed some commented code and fixed some comments.
3347
3348 (SCM_HUP_SIGNAL, SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL,
3349 SCM_SEGV_SIGNAL, SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL,
3350 SCM_SIG_ORD, SCM_ORD_SIG, SCM_NUM_SIGS): Removed.
3351
3352 * async.c: Removed some commented code.
3353
3354 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
3355
3356 * gc.c (scm_gc_mark, scm_gc_sweep, scm_must_malloc,
3357 scm_must_realloc, scm_must_free, alloc_some_heap): Use the
3358 appropriate error signalling function.
3359
3360 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
3361
3362 * root.h (scm_first_type): Removed.

3367
3368 2000-06-28 Michael Livshin <mlivshin@bigfoot.com>
3369
3370 * gc.c (scm_gc_for_newcell): don't try to do GC if it's blocked,
3371 allocate instead.
3372
3373 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
3374
3375 * async.c (scm_gc_async, scm_gc_vcell, scm_sys_gc_async_thunk):
3376 Moved to gc.c.
3377
3378 (scm_init_async): Moved initialization for scm_gc_async and
3379 scm_gc_vcell to gc.c. Moved initialization of scm_asyncs here
3380 from gc.c.
3381
3382 * async.h (scm_gc_async): Not globally visible any more.
3383
3384 * gc.c (scm_gc_stats): Made callable even from within regions
3385 where gc is blocked.
3386
3387 (scm_gc_end): Eliminate the hardcoding of the marking of the
3388 scm_gc_async from the gc core.
3389
3390 (scm_init_storage): Don't initialize the scm_asyncs list here.
3391 This is now done in asyncs.c.
3392
3393 (scm_gc_vcell): Moved here from async.c.
3394
3395 (gc_async): Renamed from scm_gc_async, moved here from async.c
3396 and made static.
3397
3398 (gc_async_thunk): Renamed from scm_sys_gc_async_thunk and moved
3399 here from async.c.
3400
3401 (mark_gc_async): New hook function for scm_after_gc_c_hook.
3402
3403 (scm_init_gc): Added initialization of scm_gc_vcell and
3404 gc_async. Further, add mark_gc_async to scm_after_gc_c_hook.
3405
3406 * init.c (scm_boot_guile_1): scm_init_gc requires asyncs to be
3407 initialized.
3408
3409 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
3410
3411 * gc.c (scm_igc): Removed commented code that once was intended
3412 to unprotect struct types with no instances.
3413
3414 * root.h (scm_type_obj_list): Removed.
3415
3416 2000-06-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
3417
3418 * async.c (scm_init_async): Switch to standard way of smob
3419 initialization.
3420
3421 2000-06-21 Michael Livshin <mlivshin@bigfoot.com>
3422
3423 * guile-doc-snarf.in: use cut instead of sed, that's much much
3424 faster. also, don't call basename more than needed. and, to gain
3425 a couple of microseconds more, don't call cat needlessly. (thanks
3426 to Brad Knotwell).
3427
3428 2000-06-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
3429
3430 * guile-snarf.awk.in, guile-snarf.in, snarf.h: Rename SCM__I to
3431 SCM_SNARF_INIT_START, SCM__D to SCM_SNARF_DOC_START, SCM__S to
3432 SCM_SNARF_DOCSTRING_START and SCM__E to SCM_SNARF_DOCSTRING_END.
3433
3434 2000-06-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3435
3436 * eval.c, eval.h (scm_top_level_lookup_closure_var): Added.
3437 #include "libguile/fluids.h".
3438
3439 * eval.h (SCM_TOP_LEVEL_LOOKUP_CLOSURE): New macro which replaces
3440 SCM_CDR (scm_top_level_lookup_closure_var) everywhere.
3441
3442 * root.h (scm_top_level_lookup_closure_var,
3443 scm_system_transformer): Removed. (It's no sense in having the
3444 *variable* be a "fluid".)
3445
3446 * root.c (mark_root): Removed marking of
3447 s->top_level_lookup_closure_var and s->system_transformer.
3448
3449 * modules.c (scm_selected_module): the_module is now a fluid.
3450
3451 2000-06-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3452
3453 * gc.h, tags.h: Be kind to compilers which must see hash signs in
3454 column 0. (Thanks to Ian Grant.)
3455
3456 * numbers.h: Put #ifdef HAVE_LONG_LONGS around declarations using
3457 the long_long type. (Thanks to Bernard Urban.)
3458
3459 2000-06-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3460
3461 * gc.c, gc.h (scm_default_init_heap_size_1,
3462 scm_default_min_yield_1, scm_default_init_heap_size_2,
3463 scm_default_min_yield_2, scm_default_max_segment_size): New global
3464 variables. Can be customized by the application before booting
3465 Guile. (We might want to be able to control these parameters
3466 dynamically through the "options interface" in the future, but
3467 note that that is additional functionality. Here we're giving
3468 default values which the environment variables can override.)
3469
3470 * list.c (scm_cons_star): Updated comment.
3471
3472 * smob.h: Changed comments for scm_make_smob_type and
3473 scm_make_smob_type_mfpe, warning that the latter might be
3474 deprecated in a future release.
3475
3476 2000-06-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
3477
3478 * list.[ch] (scm_cons_star/cons*): Renamed from
3479 scm_list_star/list*.
3480
3481 * list.[ch] (scm_list_star/list*): Provided as a deprecated alias
3482 for scm_cons_star/cons*.
3483
3484 * gc.c (scm_protect_object): Updated comment.
3485
3486 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX): Removed.
3487
3488 * tags.h (SCM_UNPACK_CAR, SCM_NDOUBLE_CELLP): Removed.
3489
3490 2000-06-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3491
3492 * init.c, init.h (scm_initialized_p): Renamed from `initialized'
3493 and made global.
3494
3495 * gdbint.c (gdb_print): Print warning instead of calling scm_write
3496 if Guile isn't yet initialized.
3497
3498 * print.c (scm_current_pstate, scm_make_print_state): Simplified
3499 tests, using the assumption that Guile has been initialized.
3500
3501 Sun Jun 18 14:45:21 2000 Greg J. Badros <gjb@cs.washington.edu>
3502
3503 * print.c (s_scm_current_pstate): Do not segfault when the
3504 print_state_pool is unitialized in `current-pstate', and better
3505 verify its state before altering it in scm_make_print_state().
3506
3507 2000-06-18 Michael Livshin <mlivshin@bigfoot.com>
3508
3509 * scmsigs.c (s_scm_sigaction): guard the SIGIOT case with an
3510 #ifdef -- it's missing on at least one platform. (thanks to
3511 Jan Nieuwenhuizen).
3512
3513 2000-06-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
3514
3515 * list.c (list*): Added documentation from common-list.scm.
3516
3517 2000-06-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
3518
3519 * gc.c (scm_unprotect_object): The reference count is guaranteed
3520 to be a positive number.
3521
3522 2000-06-15 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3523
3524 * eval.c: Updated comment above scm_map.
3525
3526 2000-06-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3527
3528 * gc.c (scm_protect_object): Avoid looking up the object handle
3529 twice.
3530 (scm_unprotect_object): Abort if scm_unprotect_object is called on
3531 an unprotected object.
3532
3533 2000-06-14 Michael Livshin <mlivshin@bigfoot.com>
3534
3535 * gc.c (scm_unprotect_object): fix a nasty typo bug (thanks to
3536 Dirk Herrmann).
3537
3538 2000-06-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3539
3540 * socket.c (scm_getsockopt): Changed type for `optlen' from int to
3541 size_t.
3542 (scm_accept, scm_getsockname, scm_getpeername, scm_recvfrom):
3543 Ditto for `tmp_size'.
3544 (scm_addr_buffer_size): Changed type from int to size_t.
3545
3546 * random.c: #include <string.h>. (Needed by memcpy.)
3547
3548 * guile-snarf.awk.in: Replace the dot_doc_file arg with "-",
3549 indicating stdin, instead of "" and don't reset ARGC. This is a
3550 workaround for `nawk' in AIX 4.3 on RS6000 but, as far as I know,
3551 it is correct, and perhaps even better.
3552
3553 2000-06-14 Gary Houston <ghouston@arglist.com>
3554
3555 * scmsigs.c (scm_init_scmsigs): if HAVE_SIGINTERRUPT is not
3556 defined, add SA_RESTART to the sigaction flags correctly
3557 (thanks to Dale P. Smith).
3558
3559 2000-06-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3560
3561 * strings.c: #include <string.h>. (Thanks to Bill Schottstaedt.)
3562
3563 * net_db.c (scm_resolv_error): Only use macro NETDB_INTERNAL if
3564 defined. It isn't on sgi irix 5.3. (Thanks to Bill Schottstaedt.)
3565
3566 * Makefile.am (.c.doc): Pipe output (the .x contents) to /dev/null.
3567
3568 2000-06-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3569
3570 * fports.c (scm_setvbuf): Use `free' instead of `scm_must_free'
3571 since read and write buffers are allocated by `malloc'.
3572
3573 * Makefile.am: Removed old test code.
3574
3575 * gh_test_c.c, gh_test_repl.c: Removed.
3576
3577 2000-06-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3578
3579 * iselect.c (SCM_NLONGBITS): Add workaround for the Sun 4.2
3580 compiler.
3581
3582 * inet_aton.c (inet_aton): Cast init value for `cp'.
3583
3584 * ramap.c (s_scm_array_fill_x): Cast `ve' properly in case
3585 `scm_tc7_uvect'.
3586
3587 * symbols.c (scm_intern_obarray_soft,
3588 scm_sysintern0_no_module_lookup): Cast `name' to unsigned char ptr
3589 in calls to scm_strhash.
3590
3591 * strports.c (st_resize_port): Substituted SCM_UCHARS for
3592 SCM_CHARS.
3593 (st_write): Cast argument to strncpy to char ptr.
3594 (scm_mkstrport): Substituted SCM_ROUCHARS for SCM_ROCHARS.
3595 (scm_strport_to_string): Cast argument to scm_makfromstr to char
3596 ptr.
3597
3598 * ports.c (scm_ungetc): Cast value to unsigned char ptr before
3599 storing in putback_buf.
3600 (scm_unread_string): Substituted SCM_ROCHARS for SCM_ROUCHARS.
3601
3602 * ioext.c (s_scm_read_line): Cast result of call to
3603 scm_do_read_line to unsigned char ptr.
3604
3605 * gdbint.c (SEND_STRING): Cast argument to char pointer.
3606
3607 * fports.c (fport_flush): Declare `ptr' as unsigned char (was
3608 char).
3609
3610 * Makefile.am (DOT_DOC_FILES): List doc-files explicitly. (We
3611 shouldn't use Make rules which aren't supported by most Make
3612 programs.)
3613 (OMIT_DEPENDENCIES): Defined to "libguile.h ltdl.h". (We don't
3614 want these dependencies recorded, since they would get bogus
3615 relative paths; libguile.h is only used in gh.h and guile.c.)
3616 (EXTRA_DOT_X_FILES, EXTRA_DOT_DOC_FILES): New variables.
3617 (guile-procedures.txt): Depend on EXTRA_DOT_DOC_FILES.
3618 (modinclude_HEADERS): Removed kw.h.
3619
3620 * guile-snarf.in: Change regexp "^SCM__I" --> "^ *SCM__I".
3621 (The preprocessor might insert spaces before the identifier.)
3622
3623 * snarf.h (SCM_SNARF_HERE, SCM_SNARF_INIT, SCM_SNARF_DOCS):
3624 Renamed from SCM_HERE, SCM_INIT, SCM_DOCS.
3625
3626 * smob.h (scm_smobfuns): Removed deprecated type.
3627
3628 * smob.c, smob.h (scm_newsmob): Removed deprecated function.
3629 (Replaced by `scm_make_smob_type'.)
3630
3631 * keywords.c (scm_tc16_kw): Removed deprecated type.
3632 (Replaced by scm_tc16_keyword.)
3633
3634 * kw.h: Removed deprecated header file.
3635
3636 * evalext.c (serial-map): Removed deprected alias for scm_map.
3637 (Has been replaced by `map-in-order'.)
3638
3639 * ramap.c (serial-array-copy!, serial-array-map!): Removed
3640 depracted aliases. (Replaced by `array-copy-in-order!' and
3641 `array-map-in-order'.)
3642
3643 2000-06-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3644
3645 * gc.h (SCM_VALIDATE_CELL): Rewritten.
3646 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
3647 SCM_SET_CELL_OBJECT): Use new version of SCM_VALIDATE_CELL.
3648 (Thanks to Han-Wen Nienhuys.)
3649
3650 2000-06-10 Michael Livshin <mlivshin@bigfoot.com>
3651
3652 * guile-doc-snarf.in: don't pipe the CPP output right into sed --
3653 write it to the temp file first and check the CPP return code.
3654 (I introduced this bug earlier, and this probably caused people
3655 with non-GNU C preprocessors to get empty *.x files and not to
3656 have the build fail right away...).
3657
3658 * scmsigs.c (s_scm_sigaction): guard the SIGSYS case with an ifdef
3659 -- at least my libc5-based Linux system doesn't define SIGSYS.
3660
3661 2000-06-08 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3662
3663 * snarf.h, guile-snarf.awk.in, guile-snarf.in: Replaced snarf
3664 markers with identifiers (SCM__I, SCM__D, SCM__S, SCM__E).
3665 (Thanks to Bernard Urban.)
3666
3667 2000-06-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3668
3669 * modules.c (scm_system_module_env_p): Fixed detection of system
3670 modules.
3671
3672 2000-06-06 Marius Vollmer <mvo@zagadka.ping.de>
3673
3674 * scmsigs.c (scm_sigaction): Silently ignore setting handlers for
3675 `program error signals' because they can't currently be handled by
3676 Scheme code.
3677
3678 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
3679
3680 * procs.h (SCM_SET_SUBRF): Added.
3681
3682 * procs.c (scm_make_subr_opt): Don't assign to SCM_SUBRF, use
3683 SCM_SET_SUBRF instead. Thanks to Bernard Urban for the bug
3684 report.
3685
3686 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
3687
3688 * gc.h (SCM_CARLOC, SCM_CDRLOC): Don't take the address of a SCM
3689 value.
3690
3691 * sort.c (scm_sorted_p, scm_merge, scm_merge_list_x,
3692 scm_merge_list_step): Don't take the address of SCM_CAR. Use
3693 SCM_CARLOC instead. Thanks to Bernard Urban for the bug report.
3694
3695 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
3696
3697 * boolean.h (SCM_TRUE_P): Removed, as people might use it as a
3698 replacement for !SCM_FALSEP.
3699
3700 * backtrace.c (display_error_body), boolean.h (SCM_BOOLP), gc.c
3701 (scm_unhash_name), gh_data.c (gh_module_lookup), load.c
3702 (scm_primitive_load), print.c (scm_simple_format), procs.c
3703 (scm_procedure_documentation), procs.h (SCM_TOP_LEVEL), ramap.c
3704 (scm_array_fill_int), scmsigs.c (scm_sigaction), stacks.c
3705 (narrow_stack, scm_make_stack, scm_stack_id), symbols.c
3706 (scm_string_to_obarray_symbol), throw.c (scm_catch,
3707 scm_lazy_catch, scm_ithrow), unif.c (scm_make_uve, scm_array_p,
3708 scm_array_set_x, scm_bit_set_star_x, scm_bit_count_star),
3709 validate.h (SCM_VALIDATE_BOOL_COPY, SCM_VALIDATE_PROC): Replace
3710 uses of SCM_TRUE_P (x) with SCM_EQ_P (x, SCM_BOOL_T).
3711
3712 2000-06-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3713
3714 * eval.c (scm_badformalsp): New static function.
3715 (SCM_CEVAL): Check arguments for procedure-with-setter closures.
3716 (Thanks to Keisuke Nishida.)
3717
3718 The major reason for Guile's slow loading speed has been the fact
3719 that a chain of Scheme level procedures has been evaluated for
3720 every top-level symbol lookup during the first pass through the
3721 code.
3722
3723 The following is a kludge which I suggested four years ago, and
3724 which I've repeatedly suggested since. Personally, I've never
3725 been bothered by Guile's slow loading speed, so I thought I would
3726 let someone else do it...
3727
3728 But since the new environments will be included first in
3729 Guile-1.5, I thought it would make people happy to get the kludge
3730 into 1.4.
3731
3732 * modules.c: Added #include "libguile/vectors.h";
3733 Added #include "libguile/hashtab.h";
3734 Added #include "libguile/struct.h";
3735 Added #include "libguile/variable.h";
3736 Capture Scheme level `module-make-local-var!' to be used in the
3737 standard eval closure.
3738 (scm_standard_eval_closure): New primitive.
3739
3740 * modules.h (scm_standard_eval_closure): Declare.
3741
3742 * eval.c (scm_lookupcar): Test for !SCM_CONSP (SCM_CAR (env))
3743 instead of SCM_TRUE (scm_procedurep (SCM_CAR (env))).
3744
3745 * symbols.c (scm_sym2vcell): Bypass dispatch in the evaluator for
3746 standard eval closures.
3747
3748 * variable.c: Code layout fixes.
3749
3750 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3751
3752 * Makefile.am: Added LIBS line to libpath which accidentally
3753 disappeared in the change of 2000-06-01.
3754 (Thanks to Dale P. Smith.)
3755
3756 2000-06-03 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3757
3758 * scmsigs.c (scm_segfault): Removed. (Was probably added by
3759 mistake since it is not mentioned in ChangeLog.)
3760
3761 * gc.h (SCM_VALIDATE_CELL): Cast result to (void) in order to
3762 avoid compiler warnings in gcc. (Does this work for other
3763 compilers?)
3764
3765 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3766
3767 * gc.h (SCM_VALIDATE_CELL): Don't "use" the value returned by
3768 abort ().
3769 (SCM_CARLOC, SCM_CDRLOC): Define directly instead of using
3770 SCM_CELL_OBJECT_0 and SCM_CELL_OBJECT_1. It's not correct to take
3771 the address of these expressions since they use SCM_VALIDATE_CELL.
3772 (Thanks to Bernard Urban.)
3773
3774 * dynl.c: Changed #include <ltdl.h> --> #include
3775 "libltdl/ltdl.h". (Thanks to Bill Schottstaedt.)
3776
3777 2000-06-01 Craig Brozefsky <craig@red-bean.com>
3778
3779 * Makefile.am: libguile_la_LDFLAGS gets -version-info args
3780 from GUILE-VERSION definition of LIBGUILE version. Added to
3781 libpath.h definitions for guileversion and libguileversion which
3782 both get their values from GUILE-VERSION definition.
3783
3784 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
3785
3786 * numbers.h (SCM_BIGP): Don't use SCM_SMOB_PREDICATE in header
3787 file: Code using numbers should not be required to include
3788 smob.h.
3789
3790 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
3791
3792 * coop-threads.c.cygnus, coop-threads.h.cygnus, fsu-pthreads.h,
3793 mit-pthreads.c, mit-pthreads.h: Deleted.
3794
3795 * Makefile.am (EXTRA_DIST), scmsigs.c, threads.[ch]: Drop
3796 references to deleted files and fsu/mit thread support in
3797 general.
3798
3799 2000-05-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
3800
3801 * hooks.c (symbol_name, scm_create_hook): Restored the original
3802 behaviour of scm_create_hook. Changing it was bad as Carl
3803 R. Witty has pointed out.
3804
3805 * gc.c (scm_init_gc): We can still rely on scm_create_hook to
3806 protect the object.
3807
3808 2000-05-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
3809
3810 * gc.c (scm_init_gc): Protect scm_after_gc_hook, since this will
3811 soon not be done by scm_create_hook any longer.
3812
3813 * hooks.c (make_hook, print_hook, scm_create_hook,
3814 scm_make_hook_with_name, scm_make_hook), hooks.h (SCM_HOOK_NAME,
3815 SCM_HOOK_PROCEDURES, SCM_SET_HOOK_PROCEDURES,
3816 scm_make_hook_with_name), init.c (scm_boot_guile_1): Hooks no
3817 longer have names. As an intermediate solution, the name
3818 predicate is emulated via object properties, but use of this
3819 feature is deprecated.
3820
3821 * hooks.h (scm_free_hook): Removed, as it is never defined.
3822
3823 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
3824
3825 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_FIXABLE):
3826 Un-deprecated since otherwise user code can't determine whether a
3827 number fits into an inum any longer. The names should be changed
3828 some time, though.
3829
3830 * numbers.c (scm_big2inum): Eliminated use of SCM_UNEGFIXABLE.
3831
3832 * tags.h (SCM_UNPACK_CAR): Deprecated.
3833
3834 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
3835
3836 * filesys.h (SCM_OPDIRP), fluids.h (SCM_FLUIDP, SCM_FLUID_NUM),
3837 fports.h (SCM_OPFPORTP, SCM_OPINFPORTP, SCM_OPOUTFPORTP), hooks.h
3838 (SCM_HOOK_ARITY), keywords.h (SCM_KEYWORDP, SCM_KEYWORDSYM),
3839 numbers.h (SCM_NUMP, SCM_BIGSIGN, SCM_BDIGITS, SCM_NUMDIGS):
3840 Replace SCM_UNPACK_CAR appropriately. Don't access cells via
3841 SCM_{SET}?C[AD]R unless they are known to be cons cells.
3842
3843 * gc.c (scm_heap_seg_data_t, scm_mark_locations, scm_cellp,
3844 init_heap_seg): Remove unused struct member variable 'valid'.
3845
3846 2000-05-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
3847
3848 * fports.c (fport_write), ports.c (scm_markstream, scm_port_mode,
3849 scm_print_port_mode), ports.h (SCM_OPPORTP, SCM_OPINPORTP,
3850 SCM_OPOUTPORTP, SCM_INPUT_PORT_P, SCM_OUTPUT_PORT_P, SCM_OPENP),
3851 procs.h (SCM_CLOSCAR), unif.h (SCM_ARRAY_NDIM, SCM_ARRAY_CONTP),
3852 variable.h (SCM_VARIABLEP): Replace SCM_UNPACK_CAR
3853 appropriately.
3854
3855 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
3856
3857 * gc.c (free_list_length), hash.c (scm_hasher), macros.c
3858 (scm_macro_type), objects.c (scm_class_of), options.c
3859 (scm_options), print.c (scm_iprin1), strports.c (st_seek), throw.c
3860 (SCM_LAZY_CATCH_P): Replace SCM_UNPACK_CAR appropriately.
3861
3862 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
3863
3864 * eval.c (scm_macroexp, SCM_CEVAL, scm_force), tags.h: Replace
3865 SCM_UNPACK_CAR with SCM_CELL_TYPE or SCM_CELL_WORD_0.
3866
3867 * eval.c (scm_force): Add documentation.
3868
3869 * eval.c (scm_force, scm_cons_source): Don't access cells via
3870 SCM_{SET}?C[AD]R unless they are known to be cons cells.
3871
3872 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
3873
3874 * strings.h (SCM_NSTRINGP, SCM_NRWSTRINGP), tags.h
3875 (SCM_NDOUBLE_CELLP), vectors.h (SCM_NVECTORP): Deprecated.
3876
3877 * gc.c (scm_igc), gc.h (SCM_PTR_MASK, SCM_PTR_LT): Removed #ifdef
3878 nosve #endif conditionally compiled code.
3879
3880 2000-05-23 Michael Livshin <mlivshin@bigfoot.com>
3881
3882 * gc.c (scm_heap_seg_data_t): fixed comment for the `span' member.
3883
3884 2000-05-22 Michael Livshin <mlivshin@bigfoot.com>
3885
3886 * guile-doc-snarf.in: put the preprocessed file through sed to
3887 trim all lines to 1024 chars. I hope it doesn't break anybody's
3888 sed. we'll see. (note: this is lossy trimming, i.e. the spill
3889 isn't wrapped around but actually chopped off. this seemed to me
3890 safe because the current snarfer doesn't understand multi-line
3891 cookies anyway. in the long term, it would be nice not to depend
3892 on AWK for anything.)
3893
3894 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): reverted
3895 the previous change to this macros, after deciding to torture the
3896 snarfer instead.
3897
3898 2000-05-21 Michael Livshin <mlivshin@bigfoot.com>
3899
3900 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): brought
3901 the yucky, ugly and nasty conditional compilation back. sorry,
3902 but it was either that or requiring GAWK to build Guile.
3903 (lots of places): removed the code that implemented the old GC
3904 scheme.
3905
3906 * init.c (scm_boot_guile_1): removed the code conditioned on
3907 !GUILE_NEW_GC_SCHEME.
3908
3909 * __scm.h: (GUILE_NEW_GC_SCHEME): removed.
3910
3911 * gc.c (scm_protect_object, scm_unprotect_object): change the
3912 implementation to more efficient (at least in the time complexity
3913 sense). the calls should now also be thread-safe -- I suspect
3914 that people expect them to be. (thanks to Han-Wen Nienhuys)
3915 (lots of places): removed the code that implemented the old GC
3916 scheme.
3917
3918 * hashtab.c (scm_hash_fn_create_handle_x): add missing
3919 SCM_REALLOW_INTS before return. I really wonder about the
3920 possible interactions between hashtables, threads & GC. it
3921 doesn't look healthy at all.
3922
3923 2000-05-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
3924
3925 * unif.c (scm_bit_count): Fixed the parameter checks. Thanks to
3926 Dale P. Smith.
3927
3928 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
3929
3930 * __scm.h (SCM_DEBUG_CELL_ACCESSES), gc.h (SCM_): Added as a new
3931 debug option to verify all accesses to cells actually access
3932 objects on the heap.
3933
3934 * gc.h (SCM_VALIDATE_CELL): Added. Only performs validation if
3935 SCM_DEBUG_CELL_ACCESSES is set to 1.
3936
3937 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
3938 SCM_SET_CELL_OBJECT): Use SCM_VALIDATE_CELL to check every cell
3939 that is accessed.
3940
3941 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
3942
3943 * gh_data.c (gh_scm2chars, gh_scm2shorts, gh_scm2longs,
3944 gh_scm2floats, gh_scm2doubles): Change !SCM_NIMP to SCM_IMP.
3945
3946 * gc.c (scm_cellp): Fixed and simplified.
3947
3948 * throw.c (JBJMPBUF, SETJBJMPBUF, SCM_JBDFRAME, SCM_SETJBDFRAME,
3949 make_jmpbuf, scm_init_throw): Now using double cells to represent
3950 jump buffers when using debug extensions.
3951
3952 (freejb): Removed.
3953
3954 2000-05-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
3955
3956 * gh.h gh_data.c gh_funcs.c (gh_new_procedure*, gh_chars2byvect,
3957 gh_shorts2svect, gh_longs2ivect, gh_ulongs2uvect, gh_floats2fvect,
3958 gh_doubles2dvect, gh_doubles2scm, gh_define, gh_lookup,
3959 gh_module_lookup): Accept const pointers as parameters.
3960
3961 * gh.h gh_data.c (gh_int2scmb): Deprecated.
3962
3963 2000-05-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
3964
3965 * __scm.h (SCM_DEBUG_REST_ARGUMENT): Renamed from
3966 SCM_DEBUG_REST_ARGUMENTS in order to clarify that we don't test
3967 the actual arguments in the list, but rather the rest argument as
3968 a list of arguments.
3969
3970 * validate.h (SCM_VALIDATE_REST_ARGUMENT): Added.
3971
3972 * async.c (scm_noop), eval.c (scm_map, scm_for_each), list.c
3973 (scm_list_star, scm_append, scm_append_x), ports.c
3974 (scm_close_all_ports_except), ramap.c (scm_array_map_x,
3975 scm_array_for_each), regex-posix.c (scm_make_regexp), stacks.c
3976 (scm_make_stack), strings.c (scm_string_append), struct.c
3977 (scm_make_struct, scm_make_vtable_vtable): Validate rest arguments.
3978
3979 * dynl.c (DYNL_GLOBAL, sysdep_dynl_link, kw_global, sym_global,
3980 scm_dynamic_link, scm_init_dynamic_linking), dynl.h
3981 (scm_dynamic_link): Removed possibility to pass flags to
3982 scm_dynamic_link, as it had no effect anyway.
3983
3984 * filesys.c (scm_fcntl): Made single optional rest argument into
3985 a standard optional argument.
3986
3987 * hooks.c (scm_run_hook): A list of rest arguments is never
3988 SCM_UNBNDP.
3989
3990 * list.c (scm_append, scm_append_x), stacks.c (scm_make_stack),
3991 strings.c (scm_string_append): Don't perform half-hearted checks
3992 to see whether the rest argument forms a proper list any more, use
3993 SCM_VALIDATE_REST_ARGUMENTS instead.
3994
3995 * ports.c (scm_close_all_ports_except): Accept empty list of rest
3996 arguments.
3997
3998 * posix.c (scm_convert_exec_args), print.c (scm_simple_format):
3999 Simplify verification of rest argument.
4000
4001 * stacks.c (scm_make_stack), stacks.h (scm_make_stack), throw.c
4002 (ss_handler, handler_message): Make first mandatory rest argument
4003 of scm_make_stack into a standard mandatory argument.
4004
4005 * unif.c (scm_transpose_array, scm_enclose_array,
4006 scm_array_in_bounds_p), unif.h (scm_transpose_array,
4007 scm_enclose_array, scm_array_in_bounds_p): Make first mandatory
4008 rest argument into a standard mandatory argument.
4009
4010 2000-05-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
4011
4012 * __scm.h: Added SCM_DEBUG as default debug option. (Thanks to
4013 Keisuke Nishida for the suggestion.) Added debug option
4014 SCM_DEBUG_REST_ARGUMENTS.
4015
4016 * eval.c (scm_map, scm_for_each): Make sure all lists have the
4017 same length. Also, removed redundant parameter checks.
4018
4019 2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
4020
4021 * Makefile.am: Let 'make clean' remove *.x and *.doc files.
4022
4023 * __scm.h: Improved explanation of giving options to make.
4024
4025 * __scm.h (SCM_DEBUG_TYPING_STRICTNESS), tags.h
4026 (SCM_STRICT_TYPING, SCM_DEBUG_TYPING_STRICTNESS): Renamed
4027 SCM_STRICT_TYPING to SCM_DEBUG_TYPING_STRICTNESS and moved the
4028 corresponding declaration and comment to __scm.h.
4029
4030 * _scm.h (errno), gc.h (SCM_CELLPTR, SCM_PTR_LT), numbers.c
4031 (scm_remainder, scm_modulo), numbers.h (SCM_SRS, SCM_MAKINUM,
4032 SCM_INUM): Removed conditionally compiled code for Turbo C.
4033
4034 * gdbint.c (gdb_maybe_valid_type_p): Eliminated call to scm_tag.
4035 That check can be assumed to be redundant except for very rare
4036 conditions that actually indicate broken heap data.
4037
4038 2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
4039
4040 * numbers.c (scm_logcount, scm_integer_length): Reordered
4041 dispatch sequence.
4042
4043 2000-05-15 Gary Houston <ghouston@arglist.com>
4044
4045 * stime.c (scm_strftime): don't reset TZ if zone is an empty
4046 string. append a "0" to the zone for TZ.
4047
4048 2000-05-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
4049
4050 * numbers.c (scm_logbit_p, scm_bit_extract): Reordered dispatch
4051 sequence.
4052
4053 (scm_bit_extract): Fixed handling of bignums.
4054
4055 2000-05-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
4056
4057 * async.c (scm_sys_gc_async_thunk), chars.h (SCM_ICHRP, SCM_ICHR,
4058 SCM_MAKICHR), continuations.h (SCM_SETJMPBUF), error.c
4059 (scm_sysmissing), error.h (scm_sysmissing), evalext.c
4060 ('serial-map), ioext.c (scm_fseek), ioext.h (scm_fseek),
4061 keywords.c (scm_tc16_kw, scm_init_keywords), ports.h (SCM_CRDY,
4062 SCM_INPORTP, SCM_OUTPORTP), ramap.c ('serial-array-copy!,
4063 'serial-array-map!), smob.c (scm_newsmob), smob.h (scm_smobfuns,
4064 scm_newsmob), tag.c (scm_tag), tag.h (scm_tag), tags.h
4065 (scm_tc16_flo, scm_tc_flo, scm_tc_dblr, scm_tc_dblc): Wrapped
4066 deprecated code between #if (SCM_DEBUG_DEPRECATED == 0) #endif.
4067
4068 * fports.c (scm_fport_buffer_add), ports.c (scm_input_port_p,
4069 scm_output_port_p), print.c (scm_get_print_state), validate.h
4070 (SCM_VALIDATE_CHAR): Replace use of deprecated macros
4071 SCM_INPORTP, SCM_OUTPORTP, SCM_ICHRP by SCM_INPUT_PORT_P,
4072 SCM_OUTPUT_PORT_P, SCM_CHARP, respectively.
4073
4074 2000-05-14 Gary Houston <ghouston@arglist.com>
4075
4076 * stime.c (scm_strftime): if HAVE_TM_ZONE is not defined, hack the
4077 TZ environment variable so that the %Z format returns the zone
4078 from the input vector instead of the system default.
4079
4080 from Keisuke Nishida:
4081 * fports.c (scm_setvbuf): minor docstring fix.
4082 * ports.h (scm_generic_fgets): obsolete prototype deleted.
4083
4084 2000-05-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
4085
4086 * __scm.h: Added new section for debugging options.
4087
4088 (SCM_DEBUG_DEPRECATED): If 1, no deprecated code is included to
4089 help developers to get rid of references to deprecated code.
4090
4091 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_UNEGFIXABLE,
4092 SCM_FIXABLE, SCM_FLOBUFLEN): These macros are no longer provided
4093 as part of the interface and are marked as deprecated in the
4094 header file.
4095
4096 * numbers.c (scm_make_real, scm_make_complex): Inlined the
4097 corresponding macros SCM_NEWREAL and SCM_NEWCOMPLEX,
4098 respectively.
4099
4100 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX, SCM_INEXP, SCM_CPLXP,
4101 SCM_REAL, SCM_IMAG, SCM_REALPART, scm_makdbl, SCM_SINGP,
4102 SCM_NO_BIGDIG, SCM_NUM2DBL, scm_dblproc): Deprecated.
4103
4104 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
4105
4106 * gc.h (scm_cell, SCM_CELL_WORD, SCM_CELL_OBJECT,
4107 SCM_SET_CELL_WORD, SCM_SET_CELL_OBJECT): Scheme cells now consist
4108 of two scm_bits_t values instead of two SCM values, because it is
4109 legal for cell entries to hold values that are not scheme objects.
4110
4111 (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR):
4112 Use SCM_SETC[AD]R to modify contents of pairs.
4113
4114 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
4115
4116 * numbers.c (IS_INF, isfinite): Added FIXME comment.
4117
4118 (scm_abs, scm_magnitude): Make these two independent of each
4119 other. scm_abs now reports an error if given a complex argument.
4120
4121 (scm_istr2flo, scm_integer_p). Use SCM_REAL_VALUE instead of
4122 SCM_REALPART if the object is known to be real.
4123
4124 (scm_init_numbers): No need to use SCM_NEWREAL macro for speed
4125 here.
4126
4127 * numbers.h (SCM_SINGP): Set to 0 instead of SCM_BOOL_F.
4128
4129 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
4130
4131 * eq.c (scm_eqv_p): Separate handling of real and complex
4132 values. Remove #ifdef SCM_BIGDIG #endif test.
4133
4134 * eval.c (SCM_CEVAL, SCM_APPLY), gh_data.c (gh_scm2floats,
4135 gh_scm2doubles), hash.c (scm_hasher), ramap.c (scm_array_fill_int,
4136 ramap_rp, scm_array_map_x), random.c (vector_scale,
4137 vector_sum_squares), unif.c (scm_make_uve, scm_array_p,
4138 scm_array_set_x): Use SCM_REAL_VALUE instead of SCM_REALPART if
4139 the object is known to be real. Use SCM_COMPLEXP instead of
4140 deprecated SCM_CPLXP. Use SCM_INEXACTP instead of deprecated
4141 SCM_INEXP.
4142
4143 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
4144
4145 * numbers.c: No need to include unif.h.
4146
4147 (IS_INF): Returned to old test for now: x == x + 1 will not work
4148 for large numbers due to rounding errors.
4149 Thanks to Kalle Olavi Niemitalo.
4150
4151 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
4152
4153 * numbers.c (scm_divbigdig): Removed outdated comment.
4154
4155 (scm_number_to_string, scm_string_to_number, scm_number_p,
4156 scm_real_p, scm_integer_p, scm_inexact_p, scm_gr_p, scm_leq_p,
4157 scm_geq_p, scm_make_rectangular, scm_make_polar,
4158 scm_inexact_to_exact): Added comments.
4159
4160 (add1, scm_init_numbers): Removed add1.
4161
4162 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
4163
4164 * numbers.c (IS_INF): The new test is x == x + 1. The old test
4165 x == x/2 did not work for zero values. Thanks to Han-Wen Nienhuys
4166 and Ivan Toshkov.
4167
4168 (scm_number_to_string, scm_sum, scm_difference, scm_two_doubles,
4169 scm_num2long, scm_num2long_long, scm_num2ulong): Reordered
4170 dispatch sequence.
4171
4172 2000-05-09 Marius Vollmer <mvo@zagadka.ping.de>
4173
4174 * scmsigs.c (take_signal): Execute SCM_ASYNC_TICK for SIGSEGV,
4175 SIGILL and SIGBUS signals. These signals are not continuable and
4176 must be handled for real right away.
4177
4178 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
4179
4180 * numbers.c (scm_zero_p, scm_positive_p, scm_negative_p,
4181 scm_real_part, scm_imag_part, scm_magnitude,
4182 scm_inexact_to_exact): Reordered dispatch sequence.
4183
4184 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
4185
4186 * feature.c: No need to include "libguile/smob.h"
4187
4188 (scm_loc_features, features, scm_add_feature, scm_init_feature):
4189 Removed variable 'scm_loc_features' as a pointer to the SCM value
4190 holding the features list. Using variable 'features' instead,
4191 which holds the interned pair. Thus, SCM_SETCDR can be used
4192 instead of pointer trickery.
4193
4194 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
4195
4196 * alist.c (scm_acons): Use SCM{_SET}?_CELL_OBJECT as long as a
4197 cell is not known to be a valid pair.
4198
4199 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
4200
4201 * eval.c (ASRTSYNTAX, scm_m_body, scm_m_letrec1): Removed
4202 ASRTSYNTAX. Using SCM_ASSYNT instead.
4203
4204 (scm_m_body): Don't create a redundant cons cell.
4205
4206 (scm_m_do): Removed redundant test 'bodycheck'.
4207
4208 (bodycheck): Removed.
4209
4210 * stacks.c (stack_depth, read_frame, read_frames): Removed
4211 redundant calculation of size, minimized some variable scopes.
4212
4213 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
4214
4215 * pairs.c (scm_cons, scm_cons2): Use SCM{_SET}?_CELL_OBJECT as
4216 long as a cell is not known to be a valid pair.
4217
4218 (scm_pair_p): Eliminated redundant SCM_IMP test.
4219
4220 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
4221
4222 * eval.c (scm_m_body, scm_macroexp, unmemocopy, scm_eval_args,
4223 scm_deval_args): Eliminated redundant SCM_IMP tests.
4224
4225 * hashtab.c (scm_ihashx, scm_sloppy_assx, scm_delx_x), weaks.c
4226 (scm_make_weak_key_hash_table, scm_make_weak_value_hash_table,
4227 scm_make_doubly_weak_hash_table): Fixed critical sections.
4228 Thanks to Keisuke Nishida.
4229
4230 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
4231
4232 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest):
4233 Fixed some goto-related initialization bugs (introduced by me).
4234
4235 2000-05-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
4236
4237 * numbers.h (SCM_INUM0): Uses SCM_MAKINUM instead of SCM_PACK.
4238
4239 * dynl.c (dynl_obj, DYNL_OBJ, get_dynl_obj): Removed.
4240
4241 (DYNL_FILENAME, DYNL_HANDLE): Use SCM_CELL... macros instead of
4242 pointer trickery.
4243
4244 (SET_DYNL_HANDLE): Added.
4245
4246 (scm_dynamic_object_p): Simplified.
4247
4248 (scm_dynamic_unlink, scm_dynamic_func): Changed comment. Deliver
4249 better error message when accessing unlinked dynamic objects.
4250 Eliminated call to get_dynl_obj.
4251
4252 2000-05-03 Marius Vollmer <mvo@zagadka.ping.de>
4253
4254 * scmsigs.c (orig_handlers) [!HAVE_SIGACTION]: Fix declaration to
4255 be an array of function pointers instead of being a pointer to an
4256 array returning function. Thanks to Kalle Olavi Niemitalo!
4257
4258 2000-05-03 Dirk Herrmann <D.Herrmann@tu-bs.de>
4259
4260 * numbers.c (scm_divbigbig, scm_divbigint), numbers.h
4261 (scm_divbigbig, scm_divbigint): Don't return zero any more to
4262 indicate that a division has a remainder, return SCM_UNDEFINED
4263 instead. It is improbable that anyone actually used these
4264 functions outside of numbers.c. For this reason and due to the
4265 change in behaviour the functions are static now. Thus, if
4266 surprisingly there are users of these functions they will at least
4267 get alarmed.
4268
4269 * numbers.c: Removed #ifdef SCM_BIGDIG #endif in those functions,
4270 that already have a clean dispatch order. Note: SCM_BIGDIG is
4271 always defined.
4272
4273 * numbers.c (scm_inexact_p): Simplified.
4274
4275 * numbers.c (scm_num_eq_p, scm_less_p, scm_max, scm_min,
4276 scm_product, scm_num2dbl, scm_angle): Reordered dispatch
4277 sequence, thereby fixing some comparisons of SCM values with
4278 integer constants.
4279
4280 * numbers.c (scm_divide): Division by zero of inums leads to an
4281 error now. (Formerly, an infinite number was returned.)
4282
4283 Respect the fact, that scm_divbigbig does now return SCM_UNDEFINED
4284 if a division has a remainder.
4285
4286 2000-05-02 Gary Houston <ghouston@arglist.com>
4287
4288 * Makefile.am (INCLUDES): add ${INCLTDL} (thanks to Tim Mooney).
4289
4290 2000-05-02 Dirk Herrmann <D.Herrmann@tu-bs.de>
4291
4292 * numbers.c (scm_logtest, scm_division): Reordered dispatch
4293 sequence, thereby fixing some comparisons of SCM values with
4294 integer constants.
4295
4296 * numbers.h (scm_makdbl): Mark as deprecated at the point of
4297 declaration.
4298
4299 * eval.c (SCM_CEVAL, SCM_APPLY), gh_data.c (gh_double2scm,
4300 gh_doubles2scm), numbers.c (scm_istr2flo, scm_max, scm_min,
4301 scm_sum, scm_difference, scm_product, scm_divide, scm_sys_expt,
4302 scm_sys_atan2, scm_make_rectangular, scm_make_polar,
4303 scm_real_part, scm_imag_part, scm_magnitude, scm_angle,
4304 scm_long2num, scm_long_long2num, scm_ulong2num), ramap.c
4305 (ramap_rp, scm_array_map_x), random.c (scm_random,
4306 scm_random_uniform, scm_random_normal_vector_x, scm_random_exp),
4307 struct.c (scm_struct_ref), unif.c (scm_array_to_list): Replace
4308 call to scm_makdbl with a call to scm_make_real or
4309 scm_make_complex, depending on whether the imaginary part is known
4310 to be zero.
4311
4312 2000-05-01 Gary Houston <ghouston@arglist.com>
4313
4314 * scmsigs.c: fix the definition of orig_handlers for the case
4315 that HAVE_SIGACTION is not defined (thanks to
4316 Kalle Olavi Niemitalo).
4317
4318 * Makefile.am: remove include_HEADERS (was libguile.h)
4319 libguile.h: moved to top level directory.
4320
4321 2000-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
4322
4323 * numbers.c (SCM_SWAP): Moved to the top of the file to allow for
4324 a wider use.
4325
4326 * numbers.c (scm_modulo, scm_gcd, scm_lcm, scm_logand, scm_logior,
4327 scm_logxor): Reordered dispatch sequence, thereby fixing some
4328 comparisons of SCM values with integer constants.
4329
4330 * number.c (scm_logtest): Removed some redundant SCM_{N}?IMP
4331 tests.
4332
4333 2000-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
4334
4335 * numbers.c (scm_quotient, scm_remainder): Removed code that was
4336 conditionally compiled based on BADIVSGNS. BADIVSGNS does not
4337 occur anywhere else throughout guile.
4338
4339 * numbers.c (scm_quotient): Fixed parameter number in error
4340 message.
4341
4342 * numbers.c (scm_remainder): Reordered dispatch sequence.
4343
4344 2000-04-25 Gary Houston <ghouston@arglist.com>
4345
4346 * posix.c (scm_execlp): docstring fix (thanks to Martin
4347 Grabmueller).
4348
4349 2000-04-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
4350
4351 * eval.c (undef_object): Made into a local static variable
4352 (suggested by Jost Boekemeier).
4353
4354 2000-04-25 Dirk Herrmann <D.Herrmann@tu-bs.de>

4356 * pairs.c (cxrs, scm_init_pairs): Simplify initialization of
4357 c[ad]+r functions.

4361
4362 * procs.h (SCM_SUBRF, SCM_DSUBRF): Access the cell words
4363 directly instead of casting a cell to a C struct.

4366
4367 Better modularization of GC extensions through new C level GC
4368 hooks:
4369
4370 * weaks.c (scm_weaks_prehistory): New function: Add
4371 scm_weak_vector_gc_init to scm_before_mark_c_hook; Add
4372 scm_mark_weak_vector_spines to scm_before_sweep_c_hook.
4373 (scm_scan_weak_vectors): New function; added to
4374 scm_after_sweep_c_hook.
4375
4376 * weaks.h (scm_weak_vectors, scm_weaks_prehistory): Added
4377 declarations.
4378
4379 * guardians.h (scm_guardian_gc_init, scm_guardian_zombify): Are
4380 now static.
4381
4382 * guardians.c (scm_guardian_gc_init): Turned into a hook function
4383 and added to scm_before_mark_c_hook.
4384 (scm_guardian_zombify): Turned into a hook function and added to
4385 scm_before_sweep_c_hook.
4386
4387 * async.c (scm_sys_gc_async_thunk): Run after-gc-hook.
4388 Added #include "libguile/gc.h".
4389
4390 * gc.h: Added #include "libguile/hooks.h".
4391
4392 * gc.c: Removed #include "libguile/guardians.h".
4393 (scm_before_gc_c_hook, scm_before_mark_c_hook,
4394 scm_before_sweep_c_hook, scm_after_sweep_c_hook,
4395 scm_after_gc_c_hook): New C level hooks.
4396 (scm_after_gc_hook): New Scheme level hook.
4397 (scm_gc_sweep): Moved scanning of weak vectors to weaks.c.
4398 (scm_igc): Moved initialization of scm_weak_vectors and the call
4399 to scm_guardian_gc_init to respective module.
4400 (scm_mark_weak_vector_spines): Moved to weaks.c;
4401 Call to scm_guardian_zombify moved to guardians.c;
4402 Run scm_before_gc_c_hook, scm_before_sweep_c_hook,
4403 scm_after_gc_c_hook at appropriate places.
4404 (scm_init_gc): Initialize scm_after_gc_hook.
4405
4406 * hooks.c, hooks.h (scm_make_hook_with_name): Removed deprecated
4407 function.

4416
4417 * *.*: Change includes so that they always use the "prefixes"
4418 libguile/, qt/, guile-readline/, or libltdl/.
4419 (Thanks to Tim Mooney.)
4420
4421 * Makefile.am (INCLUDES): Removed THREAD_CPPFLAGS and INCLTDL.
4422 (DEFS): Added. automake adds -I options to DEFS, and we don't
4423 want that.
4424 Removed all -I options except for the root source directory and
4425 the root build directory.
4426
4427 * numbers.c (scm_odd_p, scm_even_p): Use SCM_WRONG_TYPE_ARG
4428 instead of SCM_ASSERT (0, ...). (Some compilers will complain
4429 about control reaching end of function otherwise, and, besides,
4430 the new code is not less clear.)
4431
4432 * gc.c (scm_must_malloc, scm_must_realloc, scm_must_free): Added
4433 calls to malloc debugging functions.

4444
4445 * numbers.c (scm_exact_p, scm_odd_p, scm_even_p): Added
4446 documentation strings.
4447
4448 * numbers.c (scm_exact_p, scm_odd_p, scm_even_p, scm_abs,
4449 scm_quotient): Reordered dispatch sequence to first handle
4450 immediates, second handle bignums and finally handle generic
4451 functions respectively signal wrong type arguments. Hopefully
4452 this will allow for easier separation when goops is integrated.
4453
4454 2000-04-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
4455
4456 * gc.c (which_seg): Use SCM2PTR to convert a non immediate SCM

4471
4472 * eval.c (undef_cell): Removed, replaced by:

4475
4476 (scm_lookupcar, scm_lookupcar1): Use undef_object.
4477
4478 * eval.c (scm_lookupcar, scm_lookupcar1, scm_m_atfop,
4479 scm_m_atbind, CHECK_EQVISH, SCM_CEVAL), procs.h (SCM_SETCODE):
4480 Don't perform arithmetic operations with SCM values.
4481
4482 * eval.c (scm_lookupcar, scm_lookupcar1, scm_m_atfop,
4483 scm_m_atbind, scm_eval_args, scm_deval_args, SCM_CEVAL): Use
4484 symbolic names for the tc3 type codes.
4485
4486 * eval.c (scm_m_define, SCM_CEVAL, SCM_APPLY): Remove redundant
4487 cast to SCM.
4488

4493
4494 * struct.c (scm_struct_free_light, scm_struct_free_standard,
4495 scm_struct_free_entity): Use `scm_must_free' instead of `free'.
4496
4497 * procs.c (scm_make_subr_opt): Tell scm_must_realloc that we're
4498 realloc:ing scm_subr_table ("what" instead of "who").
4499
4500 * numbers.c (scm_adjbig): Ditto.
4501
4502 Tue Apr 18 08:22:41 2000 Greg J. Badros <gjb@cs.washington.edu>
4503
4504 * validate.h: Do not cast to (unsigned) in SCM_VALIDATE_INUM_RANGE
4505 when testing high-end of the range. Mikael Djurfeldt noticed this
4506 anomaly -- thanks Mikael!
4507
4508 2000-04-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
4509
4510 * unif.c (l2ra): Don't eliminate the call to scm_array_set_x
4511 itself, as was done in the previous 'patch'. (Thanks to Radey
4512 Shouman)
4513
4514 2000-04-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
4515
4516 * options.c (scm_options), read.c (recsexpr): Remove redundant
4517 SCM_IMP test.
4518

4530 (narrow_stack), unif.c (scm_cvref, scm_uniform_array_read_x,
4531 scm_raprin1): Use SCM_EQ_P to compare SCM values.
4532
4533 * strings.c (scm_makstr): Treat the msymbol slots as a field of
4534 scm_bits_t values.
4535
4536 * struct.h (SCM_SET_VTABLE_DESTRUCTOR): Treat the struct data as
4537 a field of scm_bits_t values.
4538
4539 * unif.c (l2ra): Don't test result of scm_array_set_x against

4543
4544 * script.c (scm_compile_shell_switches): Also enable

4560
4561 * struct.c (scm_alloc_struct, scm_struct_free_0,
4562 scm_struct_free_light, scm_struct_free_standard,
4563 scm_struct_free_entity, scm_make_struct, scm_make_vtable_vtable),
4564 struct.h (scm_struct_free_t, scm_alloc_struct, scm_struct_free_0,
4565 scm_struct_free_light, scm_struct_free_standard,
4566 scm_struct_free_entity): Struct data regions (and thus also
4567 vtable data regions) are now C arrays of scm_bits_t elements.
4568
4569 * gc.c (scm_gc_mark, scm_gc_sweep, scm_unhash_name): Made the
4570 mixup of glocs and structs explicit.
4571

4739 2000-04-04 Michael Livshin <mlivshin@bigfoot.com>
4740
4741 * async.h: kill the scm_async_t struct. having a heap cell
4742 pretending to be a C struct is not helthy, and is not needed here
4743 anyway, as asyncs happily fit in one heap cell.
4744
4745 * async.c: reflect the fact that asyncs are now represented by
4746 single heap cell each.

4748 2000-04-04 Gary Houston <ghouston@arglist.com>
4749
4750 * error.c (scm_syserror): save errno before doing anything else,

4811
4812 * guardians.c (scm_guardian_zombify): mark all zombies in a
4813 separate loop after processing all the currently known live
4814 guardians, so as to not introduce order dependencies (thanks to
4815 Gary Houston). note that the order problems are still there if
4816 some guardians are themselves zombies, but that's a sick case that
4817 I'm not going to worry about.
4818 also, make another outer loop to process zombified
4819 guardians (which are uncovered while marking zombies).

5030 data, use SCM_{SET_}?CELL_TYPE or SCM_{SET_}?WORD_[1-3].

5038 for scm_tc16_thread. As the current COOP threads are written, GC
5039 is not supposed to manage storage for threads.
5040
5041 * error.c (scm_error): Don't try to throw an error if
5042 scm_gc_heap_lock is true.
5043
5044 * coop.c (coop_finish): New function. Called at exit.
5045 (coop_aborthelp): Free thread structures when threads die.
5046 Finished LinuxThreads compatibility support => COOP threads now
5047 mesh with LinuxThreads.
5048
5049 * coop-threads.c (scm_call_with_new_thread, scm_spawn_thread):
5050 Changed SETCDR --> SET_CELL_WORD_1.
5051
5052 * coop-threads.c (scheme_launch_thread): Set word 1 of handle to 0
5053 when thread dies.
5054
5055 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
5056
5057 * boolean.h (SCM_TRUE_P): New macro.
5058
5059 * boolean.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOLP), pairs.h
5060 (SCM_NULLP, SCM_NNULLP): Use SCM_EQ_P to compare SCM values.
5061
5062 2000-03-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
5063
5064 * continuations.h (SCM_CONTREGS, SCM_SET_CONTREGS): New macros to
5065 access continuation data.
5066
5067 (SCM_SETJMPBUF): Deprecated. Use SCM_SET_CONTREGS instead.
5068
5069 (SCM_JMPBUF, SCM_DYNENV, SCM_THROW_VALUE, SCM_BASE, SCM_SEQ,
5070 SCM_DFRAME): Use SCM_CONTREGS instead of SCM_CHARS to access
5071 continuation data.
5072
5073 * continuations.c (scm_make_cont), init.c (start_stack),
5074 root.c (scm_internal_cwdr): Use SCM_SET_CONTREGS instead of
5075 SCM_SETJMPBUF.
5076
5077 2000-03-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
5078
5079 * symbols.h (SCM_LENGTH, SCM_SETLENGTH): Access the length field
5080 of strings and symbols by using SCM_{SET_}?CELL_WORD_0.
5081
5082 (SCM_CHARS, SCM_UCHARS, SCM_SETCHARS): Use SCM_{SET_}?CELL_WORD_1
5083 to access the char * field of strings and symbols.
5084
5085 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
5086
5087 * gc.h (SCM_NEWCELL, SCM_NEWCELL2): Use SCM_SET_CELL_TYPE to set
5088 the type entry of a new cell. Added a comment about things to
5089 remember when updating the list of free cells.
5090
5091 (SCM_FREEP, SCM_MARKEDP): Use SCM_CELL_TYPE to access the type
5092 entry of a cell.
5093
5094 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
5095
5096 * pairs.h (SCM_CAR, SCM_CDR, SCM_SETCAR, SCM_SETCDR): Use
5097 SCM_CELL_OBJECT and SCM_SET_CELL_OBJECT. This change implies that
5098 with strict type checking enabled these macros will only work if
5099 given valid SCM parameters.
5100
5101 (SCM_GCCDR): Moved to tags.h.
5102
5103 * tags.h (SCM_GCCDR): Moved here from pairs.h.
5104
5105 2000-03-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
5106
5107 * tags.h (SCM2PTR, PTR2SCM): Moved to gc.h.
5108
5109 * pairs.h (scm_cell, SCM_CELLPTR, SCM_CELL_WORD*, SCM_CELL_OBJECT*,
5110 SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*, SCM_CELL_TYPE,
5111 SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK, SCM_PTR_GT,
5112 SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC, SCM_NEWCELL,
5113 SCM_NEWCELL2): Moved to gc.h.
5114
5115 (SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR, SCM_SETAND_CDR,
5116 SCM_SETOR_CAR, SCM_SETOR_CDR): Moved to gc.h. These names should
5117 be changed, though, since the macros are not only pair related.
5118
5119 (SCMPTR): Deleted.
5120
5121 * gc.h (SCM2PTR, PTR2SCM, scm_cell, SCM_CELLPTR, SCM_CELL_WORD*,
5122 SCM_CELL_OBJECT*, SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*,
5123 SCM_CELL_TYPE, SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK,
5124 SCM_PTR_GT, SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC,
5125 SCM_NEWCELL, SCM_NEWCELL2, SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR,
5126 SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR): Moved here from
5127 tags.h and pairs.h.
5128
5129 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
5130
5131 * tags.h (SCM_STRICT_TYPING): New macro that, if defined,
5132 activates strict compile time type checking for variables of
5133 type SCM.
5134 (SCM, SCM_PACK, SCM_UNPACK): Define according to whether
5135 SCM_STRICT_TYPING or SCM_VOIDP_TEST are defined.
5136 (SCM_EQ_P): Defined as a macro equivalent for eq?.
5137
5138 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
5139
5140 * tags.h (SCM_POINTERS_MUNGED): Removed.
5141
5142 * gc.c (scm_gc_sweep, init_heap_seg): Removed use of
5143 SCM_POINTERS_MUNGED, thus fixing some illegal casts to SCM.
5144
5145 2000-03-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
5146
5147 * pairs.h (SCM_CELL_OBJECT, SCM_CELL_OBJECT_[0-3],
5148 SCM_SET_CELL_OBJECT, SCM_SET_CELL_OBJECT_[0-3], SCM_CELL_TYPE,
5149 SCM_SET_CELL_TYPE): Added a set of low level macros for accessing
5150 cell entries.
5151 (SCM_CELL_WORD_[0-3]): Renamed from the SCM_CELL_WORD[0-3].
5152
5153 * procs.h, procs.c: Instead of SCM_{SET_}?CELL_WORD[12], use the
5154 newly introduced SCM_{SET_}?CELL_OBJECT_[12] macros.
5155
5156 2000-03-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5157
5158 * tags.h: Disabled definition of SCM_VOIDP_TEST.
5159
5160 Defining SCM as void * introduces problems which haven't been
5161 handled yet. Developers who work with these issues can enable it
5162 in their working copies.
5163
5164 Disabling this definition exposes a set of newly introduced and
5165 older misuses of types which causes warning messages during
5166 compilation. We'll fix this successively.
5167
5168 * gc.c (scm_mark_locations): Changed * (SCM **) X --> * (SCM *) X
5169 in order to obtain a value of type SCM.
5170 (scm_cellp): Updated with new changes to scm_mark_locations.
5171
5172 * continuations.h (SCM_SETJMPBUF): Cast second arg into SCM.
5173
5174 * continuations.c (scm_make_cont): Removed cast of size_t into
5175 long.
5176
5177 * symbols.h (SCM_SETCHARS): Cast second arg into SCM.
5178
5179 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
5180
5181 * numbers.h (SCM_SETNUMDIGS): Use SCM_BIGSIZEFIELD macro for
5182 shifting, not constant. Thanks to Dale P. Smith.
5183
5184 * numbers.c (scm_sum, scm_difference): Don't test a SCM value
5185 for being less than zero. Decode it to a C value first. Again,
5186 thank you Dale.
5187
5188 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
5189
5190 * numbers.h, ramap.c, struct.h, vectors.h: Don't use SCM2PTR for
5191 non scheme values. If raw data is stored in SCM variables, it has
5192 to be accessed using SCM_UNPACK until a better solution is found.
5193
5194 2000-03-22 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5195
5196 * tags.h (SCM_ECONSP, SCM_NECONSP): More corrections of
5197 pointer-arithmetic induced by the SCM_PACK/UNPACK change.
5198
5199 * print.c (scm_iprin1): SCM_PACK/UNPACK corrections.
5200
5201 * gc.c (scm_gc_sweep): SCM_PACK/UNPACK corrections.
5202
5203 * eval.c (SCM_CEVAL, scm_unmemocar): SCM_PACK/UNPACK corrections.
5204
5205 * dynwind.c (scm_swap_bindings): SCM_PACK/UNPACK corrections.
5206
5207 * async.c, __scm.h: Removed lots of the old async click logic. It
5208 is possible to reinsert it by defining GUILE_OLD_ASYNC_CLICK in
5209 __scm.h. Let's try this out and dump the old code after the
5210 threads reorganization.
5211 (set-tick-rate, set-switch-rate): Conditionally removed.
5212
5213 2000-03-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5214
5215 * gc.c (scm_gc_mark): Bugfix 1: The recent SCM_PACK/UNPACK change
5216 made SCM values into pointers. This turned an arithmetic
5217 computation of the address of the vcell into a pointer-arithmetic
5218 one, thereby screwing up marking of structs.
5219 Bugfix 2: Removed incompletely introduced loop variable `j' used
5220 when protecting the tail array of a struct.
5221
5222 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
5223
5224 * struct.h (SCM_STRUCT_DATA): Don't cast SCM values to pointers.
5225
5226 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
5227
5228 * symbols.h, symbols.c (scm_strhash): Declare the string
5229 parameter as constant, since it is not modified.
5230
5231 * symbols.c (scm_intern_obarray_soft,
5232 scm_sysintern0_no_module_lookup): Can now pass constant strings
5233 to scm_strhash without need for casting.
5234
5235 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
5236
5237 * vectors.h (SCM_VELTS, SCM_VELTS_AS_STACKITEMS): Don't cast SCM
5238 values to pointers. Use SCM2PTR instead.
5239
5240 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
5241
5242 * async.c (scm_set_tick_rate, scm_set_switch_rate): Don't unpack
5243 results of SCM_INUM.
5244
5245 2000-03-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
5246
5247 * init.c (scm_boot_guile_1): Renamed GUILE_GC_TRIGGER_1 -->
5248 GUILE_MIN_YIELD_1, GUILE_GC_TRIGGER_2 --> GUILE_MIN_YIELD_2.
5249 GUILE_MIN_YIELD_X now take *positive* fractions of heap size.
5250
5251 * gc.c, gc.h (SCM_MIN_YIELD_1, SCM_MIN_YIELD_2,
5252 min_yield_fraction, min_yield, adjust_min_yield): Renamed from
5253 SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2, gc_trigger_fraction,
5254 gc_trigger, adjust_gc_trigger.
5255
5256 * gc.c (alloc_some_heap): Further improvement of minimal heap size
5257 prediction.
5258 (SCM_MAX): New macro.
5259 (scm_freelist_t): New field: collected_1. Previous amount of
5260 collected cells.
5261 (gc_sweep_freelist_finish): Trigger based on two last values of
5262 freelist->collected to avoid unnecessary allocation due to
5263 temporary peaks.
5264 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2):
5265 Adjusted to 45000 cells, 40% and 40%. Gives quick startup
5266 without extra heap allocation.
5267
5268 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
5269
5270 * numbers.h (SCM_MAKINUM): The parameter to SCM_MAKINUM should
5271 already be a C value. No need to unpack it.
5272
5273 * numbers.c (scm_long_long2num): Cast the parameter to scm_bits_t
5274 if we know it fits into an inum.
5275
5276 * ramap.c (ramap_rp): An scm_tc7_[ui]vect object does point to a
5277 field of long values. In contrast, SCM_VELTS accesses a field of
5278 SCM values.
5279
5280 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5281
5282 * gc.c (scm_gc_stats): Inserted explanation of local_scm_mtrigger
5283 etc.
5284 (scm_gc_yield_1): New variable: Holds previous yield. Used to
5285 make better judgements.
5286 (gc_sweep_freelist_finish): Inserted explanation of use of
5287 gc_trigger.
5288
5289 * print.h, stacks.h, options.c, options.h: Changed C++
5290 commentaries to C.
5291
5292 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
5293
5294 * tags.h (SCM2PTR, PTR2SCM): Use SCM_PACK / SCM_UNPACK correctly.
5295
5296 * numbers.h (SCM_INUMP, SCM_MAKINUM, SCM_INUM0, SCM_COMPLEX_REAL,
5297 SCM_COMPLEX_IMAG, SCM_NUMP, SCM_BDIGITS): Use SCM_PACK /
5298 SCM_UNPACK / SCM2PTR correctly.
5299
5300 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5301
5302 * gc.c (adjust_gc_trigger): Improved documentation.
5303 (alloc_some_heap): Since gc_trigger is used against
5304 freelist->collected, this is the value which should be used to
5305 predict minimum growth.
5306
5307 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
5308
5309 * eval.h: Fix mixup of packed/unpacked SCM values. (Thanks
5310 Thien-Thi Nguyen for the patch.)
5311
5312 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
5313
5314 * numbers.c (scm_ash): Fixed typing problems with the second
5315 parameter and added some documentation. (Thanks Thien-Thi Nguyen
5316 for indicating the problem.)
5317
5318 2000-03-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5319
5320 * gc.c, gc.h (scm_gc_yield): New variable.
5321 (adjust_gc_trigger): Use scm_gc_yield.
5322 (alloc_some_heap): Use scm_gc_yield instead of
5323 scm_gc_cells_collected.
5324
5325 * coop-threads.c: Addd #include "root.h", #include "strings.h".
5326
5327 * debug.c: Added #include "root.h". (Thanks to Thien-Thi Nguyen.)
5328
5329 * gc.c (scm_gc_for_newcell, adjust_gc_trigger): Improved GC
5330 trigger adjustmeant: Take yield (freed cells) for all freelists
5331 into account.
5332 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Tuned
5333 to 50000 cell heap with 45% trigger.
5334 (scm_gc_cells_collected): Reintroduced.
5335 (SCM_HEAP_SIZE): New macro.
5336 (scm_gc_sweep): Reintroduced correct computation of
5337 scm_cells_allocated.
5338 (scm_freelist_t): Corrected commentary for field `cluster_size':
5339 Clustersize counts objects, not cells; New member
5340 `clusters_allocated'.
5341
5342 2000-03-19 Michael Livshin <mlivshin@bigfoot.com>
5343
5344 * *.[hc]: add Emacs magic at the end of file, to ensure GNU
5345 indentation style.
5346
5347 2000-03-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
5348
5349 * threads.h: Added #include "libguile/throw.h". (Thanks to
5350 Thien-Thi Nguyen.)
5351
5352 2000-03-18 Michael Livshin <mlivshin@bigfoot.com>
5353
5354 * tags.h: (SCM_DOUBLE_CELLP, SCM_NDOUBLE_CELLP): new macros (bad
5355 names, anyone got any better ones?)
5356
5357 * gc.h: (typedef struct scm_freelist_t) remove from here.
5358
5359 * gc.c: (CELL_UP, CELL_DN) made these macros take additional
5360 parameter (the span).
5361 (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK) new macros.
5362 (typedef struct scm_freelist_t) moved here from gc.h, it had no
5363 business being externally visible.
5364 (typedef struct scm_heap_seg_data_t) renamed from
5365 scm_heap_seg_data, to be style-compliant.
5366 (scm_mark_locations) if the possible pointer points to a
5367 double-cell, check that it's properly aligned.
5368 (init_heap_seg) align double-cells properly, work with the
5369 assumption that the segment size divides cleanly by cluster size.
5370 (round_to_cluster_size) new function.
5371 (alloc_some_heap, make_initial_segment) use round_to_cluster_size
5372 to satisfy the new init_heap_seg invariant.
5373
5374 2000-03-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
5375

5430
5431 2000-03-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
5432
5433 * gc.c, gc.h: Cleanup of the change of 2000-03-15.
5434 Cluster sizes are now independent of GC trigger values.
5435 GUILE_GC_TRIGGER_n can now specify a relative trigger value:
5436 A negative integer gives fraction of total heap size in percent.
5437 (SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Default values set to -40.
5438
5439 * init.c (scm_boot_guile_1): Introduced new variable
5440 GUILE_MAX_SEGMENT_SIZE; New environment variable names:
5441 GUILE_INIT_SEGMENT_SIZE_1, GUILE_GC_TRIGGER_1,
5442 GUILE_INIT_SEGMENT_SIZE_2, GUILE_GC_TRIGGER_2
5443
5444 2000-03-16 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5445
5446 * __scm.h (GC_FREE_SEGMENTS): Disable this until we have made
5447 freeing of segment work with the new GC scheme. (Thanks to
5448 Michael Livshin.) Oops, also happened to make GUILE_NEW_GC_SCHEME
5449 the default, but I'll let this change stay in CVS Guile since this
5450 code is not expected to contain serious bugs.
5451
5452 2000-03-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
5453
5454 * gc.c, gc.h (scm_map_free_list): Define also if GUILE_DEBUG is
5455 defined.
5456 (scm_free_list_length): New procedure (GUILE_DEBUG).
5457 Fixed a small but serious bug introduced by the previous change.
5458
5459 * gc.c (scm_gc_sweep): Moved variable n_objects to inner sweep
5460 loop and declare as register.
5461
5462 * gc.c (scm_gc_sweep): Sigh... forgot to clear private freelists
5463 after GC.
5464
5465 Wed Mar 15 08:27:04 2000 Greg J. Badros <gjb@cs.washington.edu>
5466
5467 * fluids.c: Docstring patch from Keisuke Nishida. Some
5468 reindentation, too, and a couple formals renamed. Should
5469 fluid-set! return UNSPECIFIED instead of a value?
5470
5471 Wed Mar 15 08:24:58 2000 Greg J. Badros <gjb@cs.washington.edu>
5472
5473 * Makefile.am: Separate out DOT_X_FILES and DOT_DOC_FILES, and
5474 generate the latter from the concrete listing of the former. Then
5475 make guile-procedures.txt depend on DOT_DOC_FILES instead of
5476 *.doc, so that rebuilding it works.
5477
5478 Wed Mar 15 08:12:14 2000 Greg J. Badros <gjb@cs.washington.edu>
5479
5480 * libguile.h: Include libguile/validate.h. Thanks Keisuke Nishida!
5481
5482 * guile-snarf.awk.in: Replace docstring line-ending \n" and \n\n"
5483 with nothing and \n, respectively. Thanks Keisuke Nishida for
5484 noticing this problem.
5485
5486 2000-03-15 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5487
5488 * __scm.h (GUILE_NEW_GC_SCHEME): Define this if you want to test a
5489 new way of allocating heap. It makes Guile fast, but still
5490 contains bugs.
5491
5492 * gc.c, gc.h, pairs.h, init.c: Implementation of a new way of
5493 allocating heap. The basic idea is to trigger GC every Nth
5494 allocated cell and grow heap when free list runs out. The scheme
5495 has been extended so that GC isn't triggered until all remaining
5496 cells are used. The implementation is also prepared for
5497 development in the direction of POSIX threads.
5498
5499 * gc.c (SCM_EXPHEAP): In order to grow by a factor of 1.5,
5500 SCM_EXPHEAP should return half of the heap size.
5501
5502 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
5503
5504 The following change to init.c is only enabled if Guile was
5505 configured with --enable-guile-debug.
5506
5507 * init.c (scm_i_getenv_int): New function.
5508 (scm_boot_guile_1): Use the environment variables
5509 GUILE_INIT_HEAP_SIZE, GUILE_INIT_HEAP_SIZE2 to select heap size if
5510 they exist. (This may be replaced by a Scheme level mechanism in
5511 the future.)
5512
5513 * objprop.c (s_scm_set_object_property_x): Use scm_assq instead of
5514 scm_assoc. (Thanks to Keisuke Nishida.)
5515
5516 2000-03-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5517
5518 * eval.c, lang.c, lang.h (scm_lisp_nil, scm_lisp_t): Renamed from
5519 scm_nil, scm_t. (Thanks to Keisuke Nishida.)
5520
5521 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
5522
5523 * init.c (scm_boot_guile_1): Use same initial segment size for
5524 1-word and 2-word segments. Having the smaller size causes Guile
5525 to GC too often. Obviously something needs to be done to allow
5526 for a smaller 2-word segment without this to happen. (The amount
5527 of heap for each type should be automatically adapted to the
5528 application somehow.)
5529
5530 [Almost all of these changes should be documented in the NEWS
5531 file.]
5532
5533 * gc.h (scm_freelist_t): New type.
5534
5535 * pairs.h (SCM_NEWCELL, SCM_NEWCELL2): Use new style freelists.
5536
5537 * gc.c (SCM_INIT_HEAP_SIZE): Changed from 32768 --> 40000 so that
5538 all of Guile basics fits into one segment and there suitable room
5539 for work.
5540 (SCM_EXPHEAP): Now takes an argument. Grow by a factor of 1.5
5541 instead of 2.
5542 (scm_freelist, scm_freelist2): Now of type scm_freelist_t.
5543 Freelists now contains information about object span, cells
5544 collected and amount of cells in heap segments belonging to the
5545 list.
5546 (scm_heap_size, scm_gc_cells_collected): Removed.
5547
5548 * init.c (scm_boot_guile_1): Make 2-word segment 8K (512 cells).
5549
5550 * Makefile.am (libguile_la_LDFLAGS): Bumped library version
5551 number.
5552
5553 * __scm.h eq.c, eval.c, gc.c, gc.h, gh_data, hash.c, numbers.c,
5554 numbers.h, objects.c, ramap.c, random.c, unif.c, unif.h: Extensive
5555 rewrite of handling of real and complex numbers.
5556 (SCM_FLOATS, SCM_SINGLES): These #ifdef conditionals have been
5557 removed along with the support for floats. (Float vectors are
5558 still supported.)
5559
5560 * tags.h (scm_tcs_bignums): Removed.
5561 (scm_tc16_bigpos, scm_tc16_bigneg): Replaced by scm_tc16_big.
5562 Use SCM_BIGSIGN(x) to test for sign!
5563 (scm_tc16_big): The new bignum type.
5564 (SCM_REAL_PART, SCM_IMAG_PART): Removed.
5565
5566 * numbers.h (SCM_BIGSIGN): Sign moved to bit 16.
5567 (scm_makdbl): Deprecated.
5568 (SCM_NEWREAL, SCM_NEWCOMPLEX): New macros.
5569 (SCM_SINGP): Deprecated.
5570 (SCM_FLO): Removed.
5571 (SCM_INEXP, SCM_CPLXP): Deprecated.
5572 (SCM_INEXACTP, SCM_COMPLEXP): New macros.
5573 (SCM_COMPLEX_REAL, SCM_COMPLEX_IMAG): Renamed from
5574 SCM_REAL, SCM_IMAG (and now only valid for complex numbers).
5575 (SCM_REAL, SCM_IMAG): New, *deprecated*, selectors which work both
5576 for doubles and complex numbers.
5577 (SCM_REAL_VALUE): New selector for doubles.
5578 (scm_double_t, scm_complex_t): New types.
5579 (scm_dbl): Removed.
5580
5581 * numbers.c (scm_floprint, scm_floequal): Removed.
5582 (scm_print_real, scm_print_complex, scm_real_equalp,
5583 scm_complex_equalp): New functions.
5584
5585 * unif.c (scm_makflo): Removed.
5586
5587 * smob.h (SCM_SMOB_PREDICATE): New macro.
5588 (SCM_NEWSMOB2, SCM_RETURN_NEWSMOB2, SCM_NEWSMOB3,
5589 SCM_RETURN_NEWSMOB3): New macros.
5590
5591 1999-11-21 Michael Livshin <mlivshin@bigfoot.com>
5592
5593 The following changes implement primitive support for double cells
5594 (i.e. four-word cells) and change the representation of some
5595 things to multi-cells instead of cons+malloc. (Applied and
5596 modified by mdj.)
5597
5598 * pairs.h (SCM_NEWCELL2): double-cell variants of SCM_NEWCELL.
5599 (SCM_CELL_WORD, SCM_CELL_WORDLOC, SCM_SET_CELL_WORD): primitive
5600 multi-cell access macros (used by the ones below).
5601 (SCM_CELL_WORD[0-3], SCM_SET_CELL_WORD[0-3]): multi-cell access
5602 macros.
5603
5604 * gc.c (scm_freelist2): multi-cell freelists.
5605 (inner_map_free_list): map_free_list, parameterized on ncells.
5606 "nn cells in segment mm" was misleading for ncells > 1; changed to
5607 "objects". still print cells too, though.
5608 (scm_map_free_list): rewritten using inner_map_free_list.
5609 (scm_check_freelist): get freelist as parameter, since now we have
5610 more than one.
5611 (scm_debug_newcell2): multi-cell variants of
5612 scm_debug_newcell.
5613 (scm_gc_for_newcell): take ncells and freelist pointer as
5614 parameters.
5615 (scm_gc_mark): add case for tc7_pws (procedures with setters are
5616 now double cells).
5617 (scm_gc_sweep): don't free the float data, since it's not malloced
5618 anymore.
5619 (init_heap_seg): didn't understand what n_new_objects stood for,
5620 so changed to n_new_cells.
5621 (make_initial_segment): new function, makes an initial segment
5622 according to given ncells.
5623 (scm_init_storage): call make_initial_segment, for ncells={1,2,3}.
5624
5625 * numbers.c (scm_makdbl): no malloc'ing needed, so the
5626 {DEFER,ALLOW}_INTS thing removed.
5627
5628 * numbers.h (struct scm_dbl): changed to represent a double cell,
5629 with the number in the second half.
5630
5631 * dynwind.c: changed the wind-guards representation to double
5632 cell.
5633
5634 * procs.c, procs.h: changed the procedure-with-setter representation
5635 to double cell.
5636
5637 * async.c, async.h: made async representation a double cell.
5638
5639 * dynl.c: made dynamic_obj representation a double cell.
5640
5641 2000-03-13 Gary Houston <ghouston@arglist.com>
5642
5643 * ports.c (flush_void_port): renamed to flush_port_default.
5644 (end_input_void_port): renamed to end_input_default.
5645
5646 * init.c (scm_standard_stream_to_port): create a void port instead
5647 of opening /dev/null if the standard file descriptors are bad.
5648 advantages: no portability problems, doesn't waste a file descriptor,
5649 simplifies the code (thanks to Marius for the idea).
5650
5651 * vports.c (s_scm_make_soft_port): call scm_port_non_buffer.
5652
5653 * void ports: make reading from a void port give EOF instead of
5654 segv:
5655 * ports.c (s_scm_sys_make_void_port): modified docstring.
5656 (fill_input_void_port): new proc.
5657 (scm_init_ports): set up fill_input_void_port.
5658 * ports.c (scm_port_non_buffer): new proc.
5659 (scm_void_port): call scm_port_non_buffer.
5660
5661 * fports.c (scm_setvbuf): docstring: remove the fcntl documentation
5662 which was incorrectly appended.
5663
5664 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5665
5666 * guile-doc-snarf.in: Don't use absolute path for `sed'. (Note
5667 that we can't use autoconf for this. Autoconf itself relies on
5668 the existence of `sed' somewhere on your path.) (Thanks to Dirk
5669 Herrman.)
5670
5671 2000-03-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
5672
5673 * Makefile.am (libguile_la_SOURCES): Moved iselect.c here from
5674 EXTRA_libguile_la_SOURCES.
5675
5676 * iselect.h: Always declare scm_internal_select.
5677
5678 * iselect.c (scm_internal_select): Added SCM_ASYNC_TICK at the
5679 end. Also let scm_internal_select be a real function also when
5680 not using threads.
5681
5682 * __scm.h (SCM_TICK): Oops! Forgot to put SCM_ASYNC_TICK here...
5683
5684 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5685
5686 * __scm.h (SCM_ALLOW_INTS, SCM_REALLOW_INTS): Removed call to
5687 SCM_ASYNC_TICK. (This is a preparation for POSIX threads support,
5688 and kind of an experiment: Will this cause problems?)
5689
5690 Sun Mar 12 13:26:30 2000 Greg J. Badros <gjb@cs.washington.edu>
5691
5692 * Makefile.am: Added *.doc to DISTCLEANFILES.
5693
5694 2000-03-12 Gary Houston <ghouston@arglist.com>
5695
5696 * fports.c (scm_fdes_to_port): call fcntl F_GETFL to test that
5697 the fdes is valid before doing anything else. check that
5698 the file descriptor supports the modes required.
5699 (scm_fport_buffer_add): don't throw an error if fstat doesn't
5700 work: just use the default buffer size.
5701
5702 * throw.c: change an outdated comment about scm_internal_catch
5703 BODY: it doesn't take a jumpbuf arg.
5704
5705 * init.c (scm_standard_stream_to_port): install a handler in case
5706 scm_fdes_to_port throws an error. don't check here whether the
5707 file descriptor is valid, since scm_fdes_to_port will do that.
5708 set the revealed count depending on whether the port got the
5709 standard file descriptor.
5710 (stream_body_data): new type.
5711 (stream_body, stream_handler): new procs.
5712
5713 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
5714
5715 * stacks.c, stacks.h, struct.c, tags.h, unif.c (scm_bits_t):
5716 Renamed from SCMWORD.
5717
5718 * tags.h (SCM_NCELLP): Removed (SCMWORD).
5719
5720 * arbiters.c (SCM_ARB_LOCKED): Use SCM_UNPACK_CAR.
5721
5722 * async.c, boolean.h, debug.c, dynl.c, dynwind.c, eval.c, eval.h,
5723 feature.h, filesys.h, fluids.h, fports.c, fports.h, gc.c, gc.h,
5724 hash.c, keywords.h, macros.c, numbers.c, numbers.h, objects.c,
5725 objects.h, options.c, pairs.h, ports.c, ports.h, print.c,
5726 procs.h, ramap.c, read.c, smob.c, smob.h, srcprop.h, stacks.c,
5727 stacks.h, strports.c, struct.c, struct.h, tag.c, tags.h,
5728 throw.c, unif.c, unif.h, variable.h, vectors.h, weaks.c,
5729 weaks.h (SCM_PACK, SCM_UNPACK, SCM_UNPACK_CAR): Renamed from
5730 SCM_ASSCM, SCM_ASWORD, SCM_CARW).
5731
5732 * numbers.h (SCM_SRS, SCM_INUM): Corrected SCM_ASSCM/ASWORD fixes.
5733
5734 * alist.c, eval.c, net_db.c, posix.c, print.c, snarf.h, struct.c,
5735 tags.h: Fixed copyright notices.
5736
5737 * struct.c, coop-threads.c: SCM_ASSCM/ASWORD fixes.
5738
5739 2000-03-12 Marius Vollmer <mvo@zagadka.ping.de>
5740
5741 * init.c (scm_standard_stream_to_port): Check whether the file
5742 descriptor is valid and substitute "/dev/null" when not.
5743
5744 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
5745
5746 * coop-defs.h (struct timespec): Conditionally defined.
5747
5748 * coop.c (coop_condition_variable_timed_wait_mutex): Use ETIMEDOUT
5749 instead of ETIME.
5750
5751 * readline.c (match_paren): Bugfix: First arg to select is not
5752 number of descriptors but the number of the highest descriptor +
5753 1.
5754
5755 This is a preliminary attempt at a cleanup of the threads support
5756 code. It moves things to better places, makes arguments more
5757 consistent with the POSIX API (which is used in GNOME's glib), and
5758 adds new functionality.
5759
5760 * readline.c (scm_init_readline): Added new arg to scm_init_mutex.
5761
5762 * coop-defs.h (scm_mutex_trylock): New macro: alias for
5763 coop_mutex_trylock.
5764 (scm_cond_init): Changed definition to
5765 coop_new_condition_variable_init.
5766
5767 * coop.c: #include <errno.h>
5768 (coop_timeout_qinsert): Moved here from iselect.c
5769 (coop_new_mutex_init, coop_new_condition_variable_init): New
5770 functions. The strange names are temporary. Use scm_mutex_init
5771 and scm_cond_init instead.
5772 (coop_mutex_trylock): New function. Uses errno.h:EBUSY. errno.h
5773 is ANSI C, but should we check for individual error codes in
5774 configure.in?
5775 (coop_condition_variable_timed_wait_mutex): New function.
5776 (coop_key_create, coop_setspecific, coop_getspecific,
5777 coop_key_delete): New functions.
5778
5779 * iselect.c (coop_timout_qinsert): Moved to coop.c
5780
5781 2000-03-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
5782
5783 * pairs.h (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR,
5784 SCM_SETOR_CDR): Corrected SCM_ASSCM/WORD fixes.
5785
5786 * tags.h (SCM_VOIDP_TEST): Renamed from VOIDP_TEST.
5787 Layout cleanups.
5788
5789 * objects.h (SCM_CLASS_FLAGS, SCM_OBJ_CLASS_FLAGS,
5790 SCM_SET_CLASS_INSTANCE_SIZE), struct.h (SCM_STRUCT_VTABLE_DATA),
5791 proc.h (SCM_CLOSCAR): SCM_ASSCM/WORD fixes.
5792
5793 * eval.c (scm_lookupcar1): Inserted SCM_ASWORD in expressions
5794 dealing with ilocs.
5795
5796 2000-03-11 Dale P. Smith <dpsm@en.com>, applied by Greg J. Badros, <gjb@cs.washington.edu>
5797
5798 * numbers.c (scm_copy_big_dec, scm_copy_smaller, scm_big_ior,
5799 scm_big_xor, scm_big_and, scm_big_test): Added new lowlevel bignum
5800 logical functions from SCM.
5801
5802 (logand, logior, logxor, logtest, logbit?): Extended scheme
5803 logical functions to use bignums from SCM.
5804
5805 (lognot): Removed call to `SCM_VALIDATE_INUM' that prevented
5806 lognot from using bignums.
5807
5808 Thu Mar 9 11:33:25 2000 Greg J. Badros <gjb@cs.washington.edu>
5809
5810 * vectors.h (SCM_VELTS_AS_STACKITEMS): Added this macro to help in
5811 eliminating some warnings.
5812
5813 * unif.c, strports.c, print.c, options.c: Fix some warnings on
5814 mis-use of SCM/long
5815
5816 * gc.c, gc.h: Added scm_return_first_int(), and added comment re:
5817 what the scm_return_first* functions do.
5818
5819 2000-03-09 Han-Wen Nienhuys <hanwen@cs.uu.nl>, applied by Greg J. Badros, <gjb@cs.washington.edu>
5820
5821 * libguile/*.[ch]: make a distinction between SCM as a generic
5822 name for a Scheme object (now a void*), and SCM as 32 bit word for
5823 storing tags and immediates (now a long int). Introduced
5824 SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious
5825 code in the process: arbiter.c (use macros), unif.c (scm_array_p),
5826
5827 Wed Mar 8 10:15:59 2000 Greg J. Badros <gjb@cs.washington.edu>
5828
5829 * numbers.c: Use SCM_VALIDATE_LONG_COPY, and longs, not ints, in
5830 various logXXX primitives. Thanks Eric Moore!
5831
5832 Tue Mar 7 08:05:22 2000 Greg J. Badros <gjb@cs.washington.edu>
5833
5834 * run-test, remaining-docs-needed: Added these scripts. The
5835 second one is only temporary until the docstring additions are
5836 complete. run-test may best live on, but is here mostly for
5837 convenience and awareness for now.
5838
5839 * hash.c: Docs, minor cleanup patch from Dirk Herrman.
5840
5841 Thu Mar 2 16:06:58 2000 Greg J. Badros <gjb@cs.washington.edu>
5842
5843 * error.h, error.c: Added `scm_wrong_type_arg_msg' to support
5844 displaying the expected type. Use SCM_LISTn in a couple places
5845 instead of scm_cons-ing by hand.
5846
5847 * __scm.h: Added SCM_ASSERT_TYPE macro.
5848
5849 * validate.h, scm_validate.h: Added the former, as a renamed
5850 version of the latter with SCM_ASSERT_TYPE used in
5851 SCM_MAKE_VALIDATE (instead of just SCM_ASSERT)
5852
5853 * Makefile.am: Rename scm_validate.h to validate.h.
5854
5855 * *.c, *.h: Include validate.h, not scm_validate.h (old name's
5856 prefix was superfluous).
5857
5858 Thu Mar 2 15:33:12 2000 Greg J. Badros <gjb@cs.washington.edu>
5859
5860 * hashtab.c: Improved documentation for lots of functions. Added
5861 handwritten docs for `hash-fold'.
5862
5863 Thu Mar 2 15:13:25 2000 Greg J. Badros <gjb@cs.washington.edu>
5864
5865 * list.c: Added hand-written docs for `del{q,v,ete}1!'.
5866
5867 Thu Mar 2 12:38:30 2000 Greg J. Badros <gjb@cs.washington.edu>
5868
5869 * list.c: Moved append docs to append! Thanks Dirk Hermann. Also,
5870 added append docs from R4RS.
5871
5872 * strings.c: Docstring typo fix, + eliminate unneeded IMP tests.
5873 Thanks Dirk Hermann!
5874
5875 * chars.h: Provide SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR and
5876 deprecate SCM_ICHRP, SCM_ICHR, SCM_MAKICHR. Thanks Dirk Hermann!
5877
5878 * *.h, *.c: Use SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR throughout.
5879 Drop use of SCM_P for function prototypes... assume an ANSI C
5880 compiler. Thanks Dirk Hermann!
5881
5882 Sat Feb 19 12:20:12 2000 Greg J. Badros <gjb@cs.washington.edu>
5883
5884 * ports.c: Made `set-port-column!' and `set-port-line!' each
5885 return SCM_UNSPECIFIED instead of a (not-scheme-object) integer
5886 that caused a seg fault. Also fixed `set-port-column!'s
5887 docstring. Thanks Han-Wen Nienhuys for finding the bug!
5888
5889 Sun Feb 13 19:11:42 2000 Greg J. Badros <gjb@cs.washington.edu>
5890
5891 * arbiters.c, eq.c, gc.c, guardians.c, list.c, ports.c, print.c,
5892 regex-posix.c, scmsigs.c, stime.c, strings.c, variable.c, stime.c,
5893 strings.c, variable.c: Added lots of documentation, cleaned up
5894 some existing documentation. Occasionally changed formal params
5895 to match docs. Also folded an #ifdef into the inners of a
5896 primitive instead of having two copies of the primitive
5897 (`get-internal-real-time', from stime.c)
5898
5899 Sun Feb 13 18:12:19 2000 Greg J. Badros <gjb@cs.washington.edu>
5900
5901 * ports.c: Added docs for primitives missing them. Written by
5902 hand.
5903
5904 Sun Feb 13 09:40:36 2000 Greg J. Badros <gjb@cs.washington.edu>
5905
5906 * guile-doc-snarf.in: Use ${AWK} -f guile-func-name-check, not
5907 just execing guile-func-name-check. Thanks Michael Livshin!
5908
5909 Thu Feb 10 11:43:23 2000 Greg J. Badros <gjb@cs.washington.edu>
5910
5911 * guile-snarf.awk.in: Tweak to work with Sun/HP awk, removed some
5912 dead code. Patch from Michael Livshin.
5913
5914 * guile-doc-snarf.in: Tweak to work with Sun/HP sh. Patch from
5915 Michael Livshin.
5916
5917 2000-02-09 Gary Houston <ghouston@arglist.com>
5918
5919 * init.c (scm_init_standard_ports): when stdout is a tty, make the
5920 current-output-port unbuffered by default. this is less confusing
5921 for interactive use. it was line-buffered because of a
5922 performance problem with unbuffered ports, but I think it will be
5923 OK now.
5924
5925 2000-02-08 Gary Houston <ghouston@arglist.com>
5926
5927 * __scm.h: don't define long_long or ulong_long if HAVE_LONG_LONGS
5928 is not defined.
5929
5930 * stime.c (scm_localtime, scm_mktime): if neither HAVE_TM_ZONE nor
5931 HAVE_TZNAME are defined, use an empty string instead of giving two
5932 spurious compile-time errors.
5933
5934 Tue Feb 8 13:57:46 2000 Greg J. Badros <gjb@cs.washington.edu>
5935
5936 * ports.c: Doc patches from Richard Kim. Pasted from MIT Scheme.
5937 Thanks Richard!
5938
5939 Mon Feb 7 09:07:31 2000 Greg J. Badros <gjb@cs.washington.edu>
5940
5941 * macros.c: Doc patches from Richard Kim. Pasted from scm.texi.
5942
5943 Sun Feb 6 20:26:21 2000 Greg J. Badros <gjb@cs.washington.edu>
5944
5945 * pairs.c: Doc patches from Richard Kim. Pasted from MIT Scheme
5946 (which is GNU GPL'd).
5947
5948 2000-01-31 Gary Houston <ghouston@arglist.com>
5949
5950 * strings.h: don't use SCM_P. don't include <string.h>.
5951 * error.c, gh_data.c, ports.c, script.c, strop.c: include <string.h>.
5952
5953 * strings.c (scm_string_ref): make the 2nd argument compulsory.
5954 previously it defaulted to zero for no good reason that I can see.
5955 use a local variable for SCM_INUM (k). replace
5956 SCM_VALIDATE_INUM_DEF with SCM_VALIDATE_INUM_COPY.
5957
5958 (scm_makfromstr): cosmetic changes.
5959
5960 (scm_string): Accept only chars in the list, not strings, for
5961 conformance to R5RS (particularly for list->string, which is
5962 supposed to be the inverse of string->list.) remove
5963 SCM_DEFER_INTS/SCM_ALLOW_INTS, which is unnecessary since
5964 scm_makstr handles the cell allocation. when reporting wrong-type
5965 arg, don't report the position as 1.
5966
5967 * posix.c (scm_init_posix): intern PIPE_BUF if it's defined.
5968
5969 2000-01-29 Gary Houston <ghouston@arglist.com>
5970
5971 * posix.c (scm_pipe): rewrote the docstring.
5972
5973 * filesys.c (scm_select, retrieve_select_type, get_element,
5974 fill_select_type, set_element): modified so that Scheme
5975 "select" tests port buffers for the ability to provide input
5976 or accept output. Previously only the underlying file descriptors
5977 were checked. Rewrote the docstring.
5978
5979 Thu Jan 27 10:14:25 2000 Greg J. Badros <gjb@cs.washington.edu>
5980
5981 * vectors.c, symbols.c, strorder.c: Documentation cut and pasted
5982 from Gregg Reynolds. Thanks Gregg!
5983
5984 Thu Jan 27 09:59:38 2000 Greg J. Badros <gjb@cs.washington.edu>
5985
5986 * strop.c (scm_i_index): Obfuscated commented-out SCM_DEFINE by
5987 adding "x" prefix to the line so that guile-func-name-check
5988 doesn't complain unnecessarily.
5989
5990 Wed Jan 26 17:33:52 2000 Greg J. Badros <gjb@cs.washington.edu>
5991
5992 * throw.c: Factor out an #ifdef/#else/#endif choice more finely
5993 for maintainability.
5994
5995 * strop.c: Documentation added by Gregg A. Reynolds. Pasted in
5996 from qdocs, RnRs.
5997
5998 Wed Jan 26 10:02:11 2000 Greg J. Badros <gjb@cs.washington.edu>
5999
6000 * tag.c: Added doc for `tag', but mark as deprecated since Mikael
6001 suggests removing tag.c altogether (and using a new `class-of'
6002 instead).
6003
6004 * strings.c: Added documentation from Gregg A. Reynolds. Edited
6005 a bit by me to use FOO instead of @var{foo} and to have the
6006 summary come before preconditions on input. Also dropped trailing
6007 (rnrs) note.
6008
6009 * gsubr.c: Do not use SCM_DEFINE for `gsubr-apply'. Register the
6010 function with scm_make_subr_opt w/ last arg of 0 so it is not
6011 visible at the Scheme level. Mikael says that this is the right
6012 thing because the first arg to the proc is the guts of a compiled
6013 closure and shouldn't be exposed to the Scheme level.
6014
6015 Tue Jan 25 17:15:47 2000 Greg J. Badros <gjb@cs.washington.edu>
6016
6017 * sort.c: typo in comment fixed.
6018
6019 * keywords.c: Added documentation.
6020
6021 * guardians.c: Added documentation (could be better).
6022
6023 * gc.c: Added docs for gc-set-debug-check-freelist.
6024
6025 * eq.c: Added docs for eq?, eqv? equal? abridged from R4RS.
6026
6027 * boolean.c: Added docs for `not', `boolean?' (by hand).
6028
6029 Tue Jan 25 13:28:56 2000 Greg J. Badros <gjb@cs.washington.edu>
6030
6031 * random.c: Added documentation, from SLIB page:
6032 http://angela.ctrl-c.liu.se/~calle/scheme/slib_toc.html
6033
6034 Mon Jan 24 17:50:20 2000 Greg J. Badros <gjb@cs.washington.edu>
6035
6036 * variable.c, version.c: Added documentation, written by hand
6037 since I could not find anything already written that was
6038 relevant.
6039
6040 2000-01-23 Gary Houston <ghouston@arglist.com>
6041
6042 * filesys.c (scm_chown): omit port/fdes support if HAVE_FCHOWN is
6043 not defined (thanks to Richard Y. Kim).
6044
6045 Thu Jan 20 13:00:38 2000 Greg J. Badros <gjb@cs.washington.edu>
6046
6047 * Makefile.in: Removed, this is auto-generated.
6048
6049 Thu Jan 20 11:33:47 2000 Dirk Hermann <dirk@ida.ing.tu-bs.de> --applied 01/20/00 gjb
6050
6051 * list.c: Put some variable initialization code at the point of
6052 declaration; Added a comment for list*; Formatting changes.
6053
6054 * load.c: use SCM_NNULLP to make sure the end of a list is not
6055 reached yet.
6056
6057 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6058
6059 * backtrace.c (scm_display_error_message): Bugfix: Don't use
6060 result of scm_list_p as C boolean.
6061 (scm_display_error_message, scm_set_print_params_x): Use new
6062 validation macros. (Thanks to Dirk Herrmann.)
6063
6064 * net_db.c (scm_resolv_error): Cast result from hstrerror.
6065
6066 * strports.c (st_end_input): Inserted parenthesis to get operator
6067 grouping correct.
6068
6069 * list.h (scm_init_list): Removed SCM_P around prototypes.
6070
6071 * fports.c, list.c, numbers.c, ports.c, stime.c, symbols.c,
6072 filesys.c, posix.c: Converted docstrings to ANSI C format and
6073 escaped " occurring inside string literals.
6074
6075 Tue Jan 18 13:21:08 2000 Mikael Djurfeldt <mdj@r11n07-s.pdc.kth.se>
6076
6077 * posix.c (scm_mknod): Escape " occuring inside docstring.
6078
6079 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6080
6081 * alist.c, chars.c, debug.c, dynl.c, dynwind.c, error.c, eval.c,
6082 evalext.c, filesys.c, gc.c, hash.c, hashtab.c, ioext.c,
6083 keywords.c, list.c, load.c, macros.c, net_db.c, numbers.c,
6084 objprop.c, ports.c, posix.c, print.c, procprop.c, procs.c,
6085 ramap.c, regex-posix.c, root.c, scmsigs.c, simpos.c, socket.c,
6086 stacks.c, stime.c, strings.c, strop.c, strports.c, struct.c,
6087 symbols.c, throw.c, unif.c, vectors.c, version.c, vports.c,
6088 weaks.c: Converted docstrings to ANSI C format.
6089
6090 * filesys.c (scm_chmod), simpos.c (scm_system), version
6091 (scm_version), vports (scm_make_soft_port): Escape " occuring
6092 inside docstring.
6093
6094 Mon Jan 17 11:41:22 2000 Greg J. Badros <gjb@cs.washington.edu>
6095
6096 * scm_validate.h: Added SCM_VALIDATE_ULONG_COPY,
6097 SCM_VALIDATE_LONG_COPY
6098
6099 * numbers.c: Use SCM_VALIDATE_ULONG_COPY, instead of
6100 SCM_VALIDATE_INUM_COPY to let bigger numbers be used. Rename a
6101 couple of formal arguments (and fix their uses) to make arguments
6102 match the documentation.
6103
6104 2000-01-14 <mstachow@alum.mit.edu>
6105
6106 * Makefile.am: Augment path when running guile-doc-snarf so
6107 guile-func-name-check is found.
6108
6109 Fri Jan 14 09:34:55 2000 Greg J. Badros <gjb@cs.washington.edu>
6110
6111 * scm_validate.h (SCM_NUM2LONG_DEF): Fix this macro to just use
6112 def, not SCM_MAKINUM(def); thanks Janis Bzerins!
6113
6114 Wed Jan 12 00:06:53 2000 Greg J. Badros <gjb@cs.washington.edu>
6115
6116 * net_db.c (s_scm_inet_makeaddr): Use SCM_NUM2ULONG since that's
6117 the way guile-1.3.4 worked, but #if 0 out the version using
6118 SCM_VALIDATE_INUM_COPY for stricter testing.
6119
6120 Tue Jan 11 18:24:18 2000 Greg J. Badros <gjb@cs.washington.edu>
6121
6122 * guile-doc-snarf.in: Use new $fullfilename for running
6123 guile-func-name-check, and put "$fullfilename" and "$filename" in
6124 quotes at uses to make sure re-splitting on whitespace does not
6125 occur (so filenames w/ embedded whitespace would work okay, though
6126 I sure hope we never have to deal with that! :-) ). Thanks to
6127 Mikael for pointing out the source_dir != build_dir was broken.
6128
6129 Tue Jan 11 17:42:40 2000 Greg J. Badros <gjb@cs.washington.edu>
6130
6131 * scm_validate.h: Added SCM_NUM2LONG_DEF macro. Make
6132 SCM_OUT_OF_RANGE use SCM_MAKINUM, not scm_long2num. Added
6133 SCM_COERCE_ROSTRING macro. Added SCM_VALIDATE_NONEMPTYLIST
6134 macro. Fix SCM_VALIDATE_STRINGORSUBSTR macro to not use SLOPPY
6135 variants.
6136
6137 * ports.c (scm_port_closed_p): Validate that the arg is a PORT,
6138 then return whether it's an open port (was validating that it was
6139 an open port -- this was a bug I introduced back in December, but
6140 my careful reading of diffs caught it).
6141
6142 * numbers.c: Recombine the two conditional-compilation paths for
6143 all the log* primitives -- they were split based on #ifndef
6144 scm_long2num; factored out a SCM_LOGOP_RETURN macro, and fixed
6145 some bugs and inconsistencies in the two sets of implementations.
6146 (scm_lognot) Fixed *atrocious* re-use of a SCM as an integer!
6147
6148 * ioext.c: Use SCM_ASSERT_RANGE in a couple places, and
6149 SCM_VALIDATE_INUM_COPY once where it should've been used.
6150
6151 * fluids.c (scm_internal_with_fluids): Use
6152 SCM_VALIDATE_LIST_COPYLEN.
6153
6154 * filesys.c: Use SCM_NUM2LONG instead of SCM_VALIDATE_INUM_COPY;
6155 this is questionable as it relaxes type safety, but other changes
6156 were useful and all SCM_NUM2LONG's should probably be
6157 revisited. Use SCM_OUT_OF_RANGE, SCM_WRONG_TYPE_ARG.
6158
6159 * evalext.c: line-break change on 1 line.
6160
6161 * eval.c (nconc2last): Takes a non-empty list as its first
6162 argument, not just a list.
6163
6164 * dynl.c: Use new SCM_COERCE_ROSTRING macro.
6165
6166 Tue Jan 11 15:44:23 2000 Greg J. Badros <gjb@cs.washington.edu>
6167
6168 * dynl.c, feature.c, filesys.c, fports.c, list.c, load.c,
6169 net_db.c, sort.c, stacks.c, unif.c: Use SCM_WTA, SCM_MISC_ERROR
6170 where possible.
6171
6172 * symbols.c (scm_sysintern0): Fixed the function name in a
6173 scm_misc_error invocation.
6174
6175 * print.c (scm_simple_format): Do not need SCM_COERCE_SUBSTR, and
6176 use scm_return_first to ward off latent GC bug that Mikael caught.
6177
6178 * async.c: Use SCM_VALIDATE_ASYNC_COPY one place where it wasn't
6179 used before but should've been.
6180
6181 2000-01-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
6182
6183 * snarf.h (SCM_PROC1): Replaced SCM (*) (...) with
6184 SCM_FUNC_CAST_ARBITRARY_ARGS.
6185
6186 Tue Jan 11 13:44:07 2000 Greg J. Badros <gjb@cs.washington.edu>
6187
6188 * guile-func-name-check.in: Added this script to statically check
6189 #define FUNC_NAME, #undef FUNC_NAME in the source.
6190
6191 * sort.c, posix.c: Fix #undef FUNC_NAME lines to not have trailing
6192 redundant comment, semicolon; caught by new guile-func-name-check
6193 script.
6194
6195 * debug.c: Fix mistaken #define FUNC_NAME for scm_make_iloc.
6196 Caught by new guile-func-name-check-script.
6197
6198 * Makefile.am: Added guile-func-name-check to bin_SCRIPTS
6199
6200 * ramap.c: Fix #if 0'd out code to be syntactically acceptable to
6201 guile-func-name-check.
6202
6203 * guile-doc-snarf.in: Run guile-func-name-check on the file before
6204 doing the snarf.
6205
6206 Tue Jan 11 11:31:10 2000 Greg J. Badros <gjb@cs.washington.edu>
6207
6208 * fports.c, ports.c, ports.h, strports.c, vports.c: Make write
6209 port function take const void*, not void*.
6210
6211 Tue Jan 11 11:18:07 2000 Greg J. Badros <gjb@cs.washington.edu>
6212
6213 * scm_validate.h, chars.c, ports.c, print.c, read.c, strings.c,
6214 strop.c: Use SCM_VALIDATE_ICHR, SCM_VALIDATE_ICHR_COPY instead of
6215 SCM_VALIDATE_CHAR, SCM_VALIDATE_CHAR_COPY. Change made for
6216 consistency with the other macros dealing with immediate
6217 characters. (Similar to INT -> INUM change a week or so ago).
6218
6219 Tue Jan 11 10:41:46 2000 Greg J. Badros <gjb@cs.washington.edu>
6220
6221 * dynl.c, error.c, eval.c, feature.c, filesys.c, fports.c, list.c, load.c,
6222 net_db.c, read.c, socket.c: Update error messages to use ~A for
6223 %s, ~S for %S to work with new `simple-format' format and be
6224 standardized better.
6225
6226 * print.h, print.c (scm_simple_format): Added `simple-format'
6227 primitive. It's the old scm_display_error, with ARGS now a rest
6228 parameter, and the destination first instead of last (and a couple
6229 new capabilities inspired by `format' -- #t as destination means
6230 current-output-port, #f means return the formatted text as a
6231 string.
6232
6233 * gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
6234
6235 * backtrace.c (scm_display_error_message): Rewrote to use
6236 scm_simple_format() procedure.
6237
6238 * __scm.h: Added commented-out #define of GUILE_DEBUG_FREELIST
6239
6240 2000-01-09 Marius Vollmer <mvo@zagadka.ping.de>
6241
6242 Finally applied the libltdl patch from Thomas Tanner, with slight
6243 modifications.
6244
6245 * DYNAMIC-LINKING: Removed because it is obsolete.
6246 * dynl.c: Use ANSI prototypes.
6247 (sysdep_dynl_link): Use lt_dlopenext instead of lt_dlopen.
6248 * scmconfig.h.in: Do not change, as it is automatically generated.
6249
6250 1999-07-25 Thomas Tanner <tanner@ffii.org>
6251
6252 * dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c: deleted
6253 (obsolete)
6254 * Makefile.am: likewise, add INCLTDL (libltdl headers) to
6255 INCLUDES, set dlpreopened files in LDFLAGS, link libguile
6256 against libltdl
6257 * dynl.c: use libltdl if DYNAMIC_LINKING is enabled,
6258 * guile.c: register preloaded modules
6259 * scmconfig.h.in: remove obsolete symbols
6260
6261 2000-01-09 Gary Houston <ghouston@arglist.com>
6262
6263 * These changes should make it unnecessary to call tzset from
6264 Scheme after modifying the TZ environment variable, even if the
6265 system date facilities cache the value.
6266 * stime.c (setzone, scm_localtime): added comments.
6267 (tzset): don't define a noop tzset macro if HAVE_TZSET not defined.
6268 (setzone): don't call tzset.
6269 (restorezone): call tzset only if HAVE_TZSET is defined.
6270 (scm_tzset): don't define if HAVE_TZSET not defined. Change the
6271 doc string to indicate that this procedure isn't likely to do
6272 anything useful.
6273 (scm_localtime, scm_strftime, scm_mktime): call tzset if
6274 LOCALTIME_CACHE is defined.
6275
6276 2000-01-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
6277
6278 * posix.c (scm_sync): Return SCM_UNSPECIFIED.
6279
6280 2000-01-09 Gary Houston <ghouston@arglist.com>
6281
6282 * eval.c: define scm_unbound_variable_key ('unbound-variable).
6283 scm_lookupcar1: throw an error with key 'unbound-variable instead
6284 of 'misc-error when an unbound variable is encountered.
6285
6286 * filesys.c (scm_mkdir, scm_rmdir, scm_getcwd, scm_select,
6287 scm_symlink, scm_readlink, scm_lstat),
6288 posix.c (scm_setpgid, scm_setsid, scm_ctermid, scm_tcgetpgrp,
6289 scm_tcsetpgrp, scm_uname, scm_setlocale, scm_mknod, scm_nice,
6290 scm_sync),
6291 simpos.c (scm_system),
6292 stime.c (scm_times, scm_strptime):
6293 move the HAVE_XXX feature tests out of the procedure bodies.
6294 don't use SCM_SYSMISSING.
6295 scm_validate.h (SCM_SYSMISSING): removed.
6296 error.h, error.c (scm_sysmissing): comment that this is deprecated.
6297 see ChangeLog entry for 1999-12-28.
6298
6299 Sat Jan 8 19:52:04 2000 Greg J. Badros <gjb@cs.washington.edu>
6300
6301 * scm_validate.h (SCM_VALIDATE_BOOL_COPY): Fix typo.
6302
6303 Sat Jan 8 17:06:46 2000 Greg J. Badros <gjb@cs.washington.edu>
6304
6305 * backtrace.c: Fix spelling typo in a comment.
6306
6307 * snarf.h: Use new SCM_DOCS macro to encapsulate the non SCM_INIT
6308 text. Reformatted some of the expansions.
6309
6310 Fri Jan 7 15:50:46 2000 Greg J. Badros <gjb@cs.washington.edu>
6311
6312 * scm_validate.h (SCM_OUT_OF_RANGE): Use scm_out_of_range_pos to
6313 report the position of the argument.
6314
6315 * error.h, error.c (scm_out_of_range_pos): Added this function to
6316 take extra "pos" argument, the position number of the errant
6317 argument.
6318
6319 * debug.c: Use SCM_OUT_OF_RANGE instead of scm_out_of_range.
6320
6321 * snarf.h: Use SCM_HERE and SCM_INIT as names, not SCM_NOTSNARF
6322 and SCM_SNARFING. Also put the %%% in the SCM_INIT since Mikael
6323 prefers that and I'm reasonably indifferent.
6324
6325 Fri Jan 7 15:03:32 2000 Greg J. Badros <gjb@cs.washington.edu>
6326
6327 * snarf.h: Factor out differences between C++ and non-C++ into
6328 SCM_FUNC_CAST_ARBITRARY_ARGS macro. Modify all the snarf macro
6329 definitions to use SCM_NOTSNARF and SCM_SNARFING macros (like
6330 Mikael's macros, below, but changed names and SCM_SNARFING no
6331 longer expands to include %%% -- that must appear in the argument
6332 so that the token appears at the call-site as a reminder).
6333
6334 2000-01-07 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
6335
6336 * snarf.h (SCM_INSITU, SCM_INIT): New snarf macros for use in user
6337 snarf macro definitions.
6338
6339 2000-01-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6340
6341 * chars.c (scm_integer_to_char): Use Greg's nice
6342 SCM_VALIDATE_INUM_RANGE macro for argument checking for closer
6343 adherence to R5RS.
6344
6345 Thu Jan 6 11:48:49 2000 Greg J. Badros <gjb@cs.washington.edu>
6346
6347 * *.c, snarf.h: Replace GUILE_PROC1 with SCM_DEFINE1 throughout.
6348
6349 Thu Jan 6 11:22:53 2000 Greg J. Badros <gjb@cs.washington.edu>
6350
6351 * Makefile.am (ETAGS_ARGS): Switch to SCM_DEFINE, SCM_DEFINE1
6352 instead of GUILE_PROC.
6353
6354 Thu Jan 6 11:21:49 2000 Greg J. Badros <gjb@cs.washington.edu>
6355
6356 * alist.c: Do not report mismatch errors on some uses of `tmp' (do
6357 this by using SCM_ARG2 instead of `2' in the SCM_VALIDATE_CONS
6358 macro call.
6359
6360 Thu Jan 6 09:54:33 2000 Dirk Herrmann <dirk@ida.ing.tu-bs.de> --gjb applied
6361
6362 * scm_validate.h: Remove some redundant NIMP tests.
6363
6364 * alist.c: minimize scope of the tmp variables, and initialize
6365 them when declared. The strange SCM_NIMP tests are replaced by
6366 SCM_CONSP tests that more closely reflect the intended semantics.
6367 However, we don't get a performance penalty here, because the
6368 SCM_CONSP test was performed by the ALISTCELL test anyway. * The
6369 extremely ugly use of ASRTGO macros was removed: The calls to
6370 ASRTGO were not encapsulated by "#ifndef SCM_RECKLESS", but got a
6371 label parameter that only exists when SCM_RECKLESS is not defined.
6372 This works, because ASRTGO itself is defined in a way that it only
6373 makes use of the label parameter if SCM_RECKLESS is not defined
6374 (shudder!). Does guile make at all use of the possibility to
6375 define SCM_RECKLESS? * Codesize is likely to be reduced, since
6376 instead of two calls to SCM_ASSERT performed by the ALISTCELL test
6377 we now only get one test.
6378
6379 * list.c: Use SCM_NNULLP, not SCM_NIMP as appropriate. Also use
6380 SCM_NULLP instead of SCM_IMP. Drop use of "register" keyword on
6381 some variables in `list?'. Fix `reverse' and `reverse!'
6382 primitives to handle improper lists better.
6383
6384 Wed Jan 5 11:24:53 2000 Greg J. Badros <gjb@cs.washington.edu>
6385
6386 * *.[ch]: Whitespace changes -- added space after SCM_VALIDATE_*
6387 macros and SCM_DEFINE macros to match GNU coding standards.
6388
6389 Wed Jan 5 11:04:24 2000 Greg J. Badros <gjb@cs.washington.edu>
6390
6391 * *.[ch]: Replace GUILE_PROC w/ SCM_DEFINE.
6392
6393 Wed Jan 5 10:59:06 2000 Greg J. Badros <gjb@cs.washington.edu>
6394
6395 * *.[ch]: Replace SCM_VALIDATE_INT w/ SCM_VALIDATE_INUM for
6396 better consistency with the names of other SCM_VALIDATE_ macros
6397 and better conformance to guile naming policy.
6398
6399 Wed Jan 5 10:50:39 2000 Greg J. Badros <gjb@cs.washington.edu>
6400
6401 * ports.c (s_scm_close_all_ports_except): Use SCM_ARG1 in a
6402 SCM_VALIDATE instead of 1 to avoid a check on the argument (since
6403 it's not the actual name of the formal).
6404
6405 * guile-snarf.awk.in: Do argument/number mismatch checking and
6406 print warnings in an Emacs compile-mode parseable format.
6407
6408 * struct.c: Use SCM_ASSERT_RANGE instead of SCM_ASSERT w/
6409 SCM_OUTOFRANGE as 3rd argument.
6410
6411 * random.c: Fix argument/number mismatch (that I introduced :-( ).
6412
6413 * __scm.h: Do not #define SCM_ARG* when snarfing;
6414 lets us distinguish between 1 and SCM_ARG1 when snarfing as only
6415 the former (using the number) requires the argument to match the
6416 formal in the current argument snarfing check.
6417
6418 * snarf.h: Give new definition of SCM_ASSERT when in
6419 snarfing mode to output a lexically-identifiable sequence that the
6420 guile-snarf.awk script uses to verify argument/position matching.
6421
6422 * ramap.c: Remove extraneous #undef FUNC_NAME.
6423
6424 Wed Jan 5 08:36:38 2000 Greg J. Badros <gjb@cs.washington.edu>
6425
6426 * guile-doc-snarf.awk.in: Removed -- guile-snarf.awk.in is the
6427 current version of the same functionality; it writes the .x output
6428 to stdout instead of directly into the file.
6429
6430 Wed Jan 5 08:15:04 2000 Greg J. Badros <gjb@cs.washington.edu>
6431
6432 * unif.c, symbols.c, strings.c, stacks.c, random.c, print.c,
6433 posix.c: Eliminated a bunch of SCM_NIMP(..)s that are now
6434 redundant with the safer macros. Patch from Dirk Hermann applied
6435 by hand. Thanks Dirk!
6436
6437 * scm_validate.h: Added SCM_VALIDATE_VECTOR_OR_DVECTOR for some
6438 uses in random.c.
6439
6440 * ramap.c: whitespace change.
6441
6442 Tue Jan 4 14:21:35 2000 Greg J. Badros <gjb@cs.washington.edu>
6443
6444 * options.c, objects.c, keywords.c, gc.c: Some redundant SCM_NIMP
6445 removals from Dirk Hermann.
6446
6447 * alist.c: Rename formals to match the parameter names in the
6448 documentation, updates to documentation. Thanks Dirk Hermann!
6449
6450 2000-01-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6451
6452 * eval.c (SCM_CEVAL): Reverse order of
6453 scm_stack_checking_enabled_p and SCM_STACK_OVERFLOW_P
6454 (Thanks to Brad Knotwell.)
6455
6456 Mon Jan 3 08:30:02 2000 Greg Harvey <Greg.Harvey@thezone.net> (applied --01/03/00 gjb)
6457
6458 * gc.c (scm_debug_newcell): Added SCM_SETCAR of the newly
6459 allocated cell.
6460
6461 * pairs.h: Added a comment about the need for the SCM_SETCAR in
6462 SCM_NEWCELL macro.
6463
6464 Mon Jan 3 08:25:19 2000 Greg J. Badros <gjb@cs.washington.edu>
6465
6466 * dynl-vms.c, debug.c, coop-threads.c, backtrace.c, eval.c: More
6467 SCM_NIMP tests that were redundant are now eliminated. Patches
6468 from Dirk Hermann applied by hand.
