336 expects a null-terminated string in the locale encoding, but

521 hash.c, gc.c, gc-card.c, convert.i.c, backtrace.c, strop.c,
522 strorder.c, strports.c, struct.c, symbols.c, unif.c, ports.c: Use
523 SCM_I_STRING_CHARS, SCM_I_STRING_UCHARS, and SCM_I_STRING_LENGTH
524 instead of SCM_STRING_CHARS, SCM_STRING_UCHARS, and
525 SCM_STRING_LENGTH, respectively. Also, replaced scm_return_first
526 with more explicit scm_remember_upto_here_1, etc, or introduced
527 them in the first place.
529 * posix.c (WITH_STRING): New helper macro. Use it where one
530 locale string is needed for a short piece of code.
531 (STRING_SYSCALL): New helper macro. Use it instead of SCM_SYSCALL
532 when one locale string is needed.
533 (scm_mkstemp): Convert tmpl to a locale string.
534 (scm_putenv): Rewritten to use only C strings.
535 (scm_setlocale, scm_crpt): Convert argument strings to locale
538 2004-08-11 Marius Vollmer <marius.vollmer@uni-dortmund.de>
540 * load.c (scm_primitive_load_path): Do not check for absolute
541 filenames when scm_sys_search_load_path returns false, which will
542 return absolute filenames unchanged.
544 2004-08-11 Marius Vollmer <mvo@zagadka.de>
546 * gc.c, procprop.c (scm_init_storage, scm_stand_in_procs,
547 scm_stand_in_proc): Use a hastable for scm_stand_in_procs instead
548 of an alist. Thanks to Matthias Koeppe!
550 2004-08-10 Marius Vollmer <marius.vollmer@uni-dortmund.de>
552 * strings.h, deprecated.h (SCM_STRING_COERCE_0TERMINATION_X):
553 Moved from string.h to deprecated.h.
555 * deprecated.c, deprecated.h (SCM_CHARS, SCM_LENGTH): Removed.
557 * strings.h, strings.c (SCM_MAKE_STRING_TAG): Renamed to
558 SCM_I_MAKE_STRING_TAG, changed all uses.
559 (SCM_STRING_CHARS, SCM_STRING_UCHARS, SCM_STRING_LENGTH): Renamed
560 to SCM_I_STRING_CHARS, SCM_I_STRING_UCHARS, and SCM_I_LENGTH
561 respectively. For a short time, the old names are still there as
562 aliases. Not all uses have been changed yet, but the ones in
564 (SCM_STRING_MAX_LEN): Do not hardcode to 24 bits, compute from
566 (scm_is_string, scm_from_locale_string, scm_from_locale_stringn,
567 scm_take_locale_string, scm_take_locale_stringn,
568 scm_to_locale_string, scm_to_locale_stringn,
569 scm_to_locale_stringbuf): New.
570 (scm_c_string2str, scm_c_substring2str): Deprecated by moving to
571 deprecated.[hc]. Implemented in terms of the new functions above.
572 (scm_take_str, scm_take0str, scm_mem2string, scm_str2string,
573 scm_makfrom0str): Reimplemented in terms of the new functions from
574 above. They will be discouraged shortly.
575 (scm_substring): Do not use scm_mem2string.
576 (scm_i_allocate_string_pointers, scm_i_free_string_pointers): New,
577 to replace similar code from posix.c, simpos.c, and dynl.c.
578 (scm_string_append): Use memcpy instead of explicit loop. Do not
579 use register keyword. Use plain 'char' instead of 'unsigned
582 * strports.c (scm_mkstrport): Use SCM_I_STRING_UCHARS instead of
583 SCM_STRING_UCHARS. Use SCM_I_STRINGP instead of SCM_STRINGP.
585 * strop.c (scm_i_index): Replaced SCM_STRINGP, SCM_STRING_CHARS,
586 and SCM_STRING_LENGTH with SCM_I_STRINGP, SCM_I_STRING_CHARS, and
587 SCM_I_STRING_LENGTH, respectively. Pass string object directly,
588 not as a pointer. Use scm_remember_upto_here_1 to protect it.
590 * read.c (scm_input_error): Use a SCM value for 'fn', not a C
591 string. This avoids a conversion round-trip.
593 * gh_data.c: Replaced SCM_STRINGP, SCM_STRING_CHARS, and
594 SCM_STRING_LENGTH with SCM_I_STRINGP, SCM_I_STRING_CHARS, and
595 SCM_I_STRING_LENGTH, respectively.
596 (gh_scm2newstr): Implement in terms of scm_to_locale_string.
598 * environments.c: Instead calling scm_puts on the SCM_STRING_CHARS
599 of a string, call scm_display on the string itself.
601 * dynwind.c, dynwind.h (scm_frame_free): New.
603 * stime.c, socket.c, simpos.c, procs.c, posix.c, ports.c,
604 net_db.c, fports.c, filesys.c, eval.c, deprecation.c, dynl.c:
605 Replaced uses of SCM_STRING_CHARS with proper uses of
606 scm_to_locale_string. Replaced SCM_STRINGP with scm_is_string.
607 Replaced scm_mem2string with scm_from_locale_string.
609 * simpos.c, posix.c (allocate_string_pointers, environ_list_to_c):
610 Removed, replaced all uses with scm_i_allocate_string_pointers.
612 * load.h, load.c (scm_internal_parse_path): Removed.
613 (scm_parse_path): Use scm_string_split to do the work.
614 (scm_init_load_path): Use scm_parse_path instead of
615 scm_internal_parse_path.
616 (scm_search_path): Rewritten string handling part of the code in
617 terms of scm_to_locale_stringbuf and so that it is thread safe.
619 * error.c (scm_error_scm): Throw directly instead of calling
620 scm_error, this avoids the back and forth conversion of SUBR and
621 MESSAGE and also plugs a memory leak.
622 (scm_error): Call scm_error_scm.
624 * backtrace.c: Replaced SCM_STRINGP with scm_is_string.
625 (display_header): Print FNAME when it is true, not
626 merely when it is a string.
628 * strings.h (SCM_SET_STRING_LENGTH, SCM_SET_STRING_CHARS): Removed
629 unceremoniously. They were unused by Guile itself, and external
630 use should stop immediately.
633 2004-08-10 Marius Vollmer <mvo@zagadka.de>
635 * numbers.h, number.c, deprecated.h, deprecated.c (scm_round,
636 scm_truncate): Renamed to scm_c_round and scm_c_truncate;
637 deprecated versions installed in deprecated.h and deprecated.c.
640 2004-08-06 Rob Browning <rlb@defaultvalue.org>
642 * net_db.c (scm_resolv_error): don't cause an exception while
643 trying to throw an exception -- call scm_misc_error with correct
644 arguments. The previous arguments needed a format escape that
645 wasn't in any of the format strings.
647 2004-08-06 Kevin Ryde <user42@zip.com.au>
649 * ramap.c (scm_array_fill_x): For byvect char fill, force signed char
650 so as not to depend on signedness of plain char. For byvect range
651 check, throw out-of-range rather than wrong-type-arg.
653 * unif.c (scm_uniform_vector_ref, scm_array_set_x): For byvect, force
654 signed byte range checks by using scm_to_schar and scm_from_schar,
655 don't want to depend on signedness of C char.
657 2004-08-05 Kevin Ryde <user42@zip.com.au>
659 * arbiters.c (scm_try_arbiter): Use scm_i_misc_mutex instead of
661 (scm_release_arbiter): Use scm_i_misc_mutex so return value can be
662 guaranteed if multiple threads compete to unlock.
663 Update docstrings per doc/ref/api-scheduling.texi.
665 * filesys.c (scm_copy_file): Use fstat on the input fd rather than
666 stat on the filename, to be certain a file rename can't mean we get
667 info on one filesystem object but open another. This fstat usage is
668 similar to Emacs copy-file.
670 * posix.c (scm_setgroups): Enhance docstring, per doc/ref/posix.texi.
672 * simpos.c (scm_system_star): Change scm_from_long to scm_from_int on
673 SIGINT and SIGQUIT, since those values are ints.
675 2004-08-03 Marius Vollmer <marius.vollmer@uni-dortmund.de>

697 (scm_make_real, scm_num2dbl, scm_float2num, scm_double2num):
698 Discouraged by moving to discouraged.h and discouraged.c.
699 Replaced all uses with scm_from_double.
700 (scm_num2float, scm_num2double): Discouraged by moving prototype
701 to discouraged.h and rewriting in terms of scm_to_double.
702 Replaced all uses with scm_to_double.
703 (scm_to_double): Do not implement in terms of scm_num2dbl, use
705 (scm_from_double): Do not implement in terms of scm_make_real, use

731 scm_num2ulong_long): Discouraged by moving to discouraged.h and
732 discouraged.c and reimplementing in terms of scm_from_* and
733 scm_to_*. Changed all uses to the new scm_from_* and scm_to_*

746 and current usage and migration.
748 2004-07-31 Kevin Ryde <user42@zip.com.au>
750 * error.c (scm_strerror): Use scm_i_misc_mutex around strerror since
751 it's not thread safe.
752 (scm_syserror): Use scm_strerror rather than SCM_I_STRERROR, to take
754 * fports.c (scm_open_file): Use scm_strerror likewise.

810 SCM_I_SSIZE_MIN, SCM_I_SSIZE_MAX, and SCM_I_SIZE_MAX macros for
811 the limits. Those are always defined.
813 2004-07-29 Kevin Ryde <user42@zip.com.au>
815 * posix.c (scm_ttyname): Use scm_i_misc_mutex for thread safety.

848 scm_from_*, as appropriate.
850 * dynwind.c (scm_i_dowinds): Removed unused code that would call
851 the unexisting scm_cross_dynwind_binding_scope for inums on the
854 2004-07-10 Marius Vollmer <marius.vollmer@uni-dortmund.de>
856 * socket.c (ipv6_net_to_num, scm_from_ipv6): Renamed
857 ipv6_net_to_num to scm_from_ipv6, for converting from an IPv6
858 byte-wise address to a SCM integer. Changed all uses.
859 (ipv6_num_to_net, scm_to_ipv6): Renamed ipv6_num_to_net to
860 scm_to_ipv6 and added type and range checking, for converting from
861 an IPv& byte-wise address to a SCM integer. Changed all uses.

872 SCM_VALIDATE_INUM_DEF_COPY, SCM_VALIDATE_INUM_RANGE,
873 SCM_VALIDATE_INUM_RANGE_COPY): Deprecated because they make the
874 fixnum/bignum distinction visible. Changed all uses to
875 scm_to_size_t or similar.
877 2004-07-09 Marius Vollmer <marius.vollmer@uni-dortmund.de>
879 * cpp_cnvt.awk: Use scm_from_int instead of SCM_MAKINUM.
881 2004-07-10 Kevin Ryde <user42@zip.com.au>
883 * hash.c (scm_hashq, scm_hashv, scm_hash): Restrict to size>=1 rather
884 than size>=0, since 0<=hash<size cannot be satisfied for size==0, and
885 such a size causes divide-by-zeros in scm_hasher.
887 * regex-posix.c (scm_make_regexp): Free rx on error, to avoid memory
890 2004-07-08 Marius Vollmer <marius.vollmer@uni-dortmund.de>

893 Rewritten using the same logic as scm_to_signed_integer and
894 scm_to_unsigned_integer, respectively, which is better(tm). Also,
895 use CHAR_BIT instead of hardcoding 8.
896 (LLONG_MIN, LLONG_MAX, ULLONG_MAX): Removed and used
897 SCM_I_LLONG_MIN etc. instead.
899 * numbers.h (SCM_MAKINUM, SCM_I_MAKINUM): Renamed SCM_MAKINUM to
900 SCM_I_MAKINUM and changed all uses.

903 * gen-scmconfig.c (SCM_I_LLONG_MIN, SCM_I_LLONG_MAX,
904 SCM_I_ULLONG_MAX): Instead of hard-coding the numbers, compute
905 them by assuming twos-complement.
907 2004-07-07 Marius Vollmer <marius.vollmer@uni-dortmund.de>
909 * gen-scmconfig.h.in: Added all the new SCM_I_GSC_*_LIMITS that
910 configure now produces.
911 * gen-scmconfig.c: Use them to output SCM_T_INT8_MIN, etc
912 definitions, giving the limits of the integer types defined by
913 Guile. Also, output a hard coded SCM_I_LLONG_MIN, etc since
914 LLONG_MIN or LONG_LONG_MIN is hard to get at.
916 * numbers.h (scm_to_short, scm_to_ushort): It's SHRT_MIN, etc, not
918 (scm_to_size_t): Use SIZE_MAX instead of cooking our own.

931 * deprecated.h, boolean.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOL,
932 SCM_NEGATE_BOOL, SCM_BOOLP): Deprecated by moving into
933 "deprecated.h". Replaced all uses with scm_is_false, scm_is_true,
934 scm_from_bool, and scm_is_bool, respectively.
936 * boolean.h (scm_is_bool): Fix bug in prototype.
937 (scm_from_bool): The argument is "x" not "f", stupid.

953 * boolean.h, boolean.c (scm_is_true, scm_is_false, scm_from_bool,
956 2004-06-27 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
958 * backtrace.c (display_expression, display_frame): Call
959 scm_i_unmemoize_expr for unmemoizing a memoized object holding a
960 single memoized expression.
962 * debug.c (memoized_print): Don't try to unmemoize the memoized
963 object, since we can't know whether it holds a single expression
966 (scm_mem_to_proc): Removed check for lambda expression, since it
967 was moot anyway. Whoever uses these functions for debugging
968 purposes should know what they do: Creating invalid memoized code
969 will cause crashes, independent of whether this check is present
972 (scm_proc_to_mem): Take the closure's code as it is and don't
973 append a SCM_IM_LAMBDA isym. To allow easier debugging, the
974 memoized code should not be modified.
976 * debug.[ch] (scm_unmemoize, scm_i_unmemoize_expr): Removed
977 scm_unmemoize from public use, but made scm_i_unmemoize_expr
978 available as a guile internal function instead. However,
979 scm_i_unmemoize_expr will only work on memoized objects that hold
980 a single memoized expression. It won't work with bodies.
982 * debug.c (scm_procedure_source), macros.c (macro_print), print.c
983 (scm_iprin1): Call scm_i_unmemocopy_body for unmemoizing a body,
984 i. e. a list of expressions.
986 * eval.c (unmemoize_exprs): Drop internal body markers from the
987 output during unmemoization.
989 * eval.[ch] (scm_unmemocopy, scm_i_unmemocopy_expr,
990 scm_i_unmemocopy_body): Removed scm_unmemocopy from public use,
991 but made scm_i_unmemocopy_expr and scm_i_unmemocopy_body available
992 as guile internal functions instead. scm_i_unmemoize_expr will
993 only work on a single memoized expression, while
994 scm_i_unmemocopy_body will only work on bodies.
996 2004-06-21 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
998 * eval.c (unmemoize_exprs): Handle semi-memoized code.
1000 (scm_cons_source, scm_primitive_eval): Prefer higher level
1001 predicate SCM_FALSEP over SCM_IMP.
1003 2004-06-15 Rob Browning <rlb@defaultvalue.org>
1005 * script.c (scm_shell_usage): minor phrasing change.
1007 * gc_os_dep.c: update ifdefery for macosx.
1008 (scm_get_stack_base): separate result initialization from
1009 declaration to slience warnings with macosx and hp-ux using gcc
1010 3.3. Thanks to Andreas Vögele.
1012 2004-06-13 Han-Wen Nienhuys <hanwen@xs4all.nl>
1014 * eval.c (unmemoize_exprs): use SCM_CONSP for the loop condition.
1016 2004-06-06 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
1018 * list.[ch] (scm_i_finite_list_copy): New internal function to
1019 copy lists that are known to be finite (though not necessarily
1022 * debug.c (scm_procedure_source): Don't have scm_unmemocopy treat
1023 a closure's argument list like an expression of a body.
1025 * eval.c (unmemoize_expression, unmemoize_exprs, unmemoize_and,
1026 unmemoize_begin, unmemoize_case, unmemoize_cond, unmemoize_delay,
1027 unmemoize_do, unmemoize_if, unmemoize_lambda, unmemoize_let,
1028 unmemoize_letrec, unmemoize_letstar, unmemoize_or,
1029 unmemoize_set_x, unmemoize_apply, unmemoize_atcall_cc,
1030 unmemoize_at_call_with_values, unmemoize_future, sym_atslot_ref,
1031 unmemoize_atslot_ref, sym_atslot_set_x, unmemoize_atslot_set_x,
1032 unmemoize_builtin_macro): New static functions and symbols.
1034 (scm_unmemocopy): Rewritten in terms of the above. scm_unmemocopy
1035 now has a slightly different meaning: The memoized form that is
1036 receives as its argument is now interpreted as a sequence of
1037 expressions from a body.
1039 (unmemocar, scm_unmemocar): Since the whole functionality of
1040 unmemocar and scm_unmemocar is not needed any more, scm_unmemocar
1041 has its old content back and is deprecated, while unmemocar has
1044 (SCM_BIT7): Removed.
1046 (CEVAL): For unmemoizing a single expression, call
1047 unmemoize_expression instead of scm_unmemocopy, which now expects
1048 a sequence of body expressions. Eliminated unnecessary empty
1049 environment frame when executing let* forms. Eliminated
1050 unmemoization step from evaluator.
1052 2004-06-02 Marius Vollmer <marius.vollmer@uni-dortmund.de>
1054 * eval.c (scm_macroexp, macroexp): Renamed scm_macroexp to
1055 macroexp and made static. Added new version of scm_macroexp that
1056 emits a deprecation warning and then calls macroexp.
1057 (scm_m_undefine): Issue deprecation warning.
1059 2004-05-30 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
1061 * eval.c (lookup_global_symbol, literal_p, try_macro_lookup):
1062 Modified to make set! work on symbols that represent syntactic
1065 2004-05-26 Han-Wen Nienhuys <hanwen@xs4all.nl>
1067 * gc.h (SCM_CELL_OBJECT_LOC): use SCM_GC_CELL_OBJECT to prevent
1068 compound expression as lvalue errors.
1070 2004-05-24 Marius Vollmer <mvo@zagadka.de>
1072 * dynwind.c (winder_mark): Use SCM_PACK to correctly convert the
1073 WINDER_DATA to a SCM.
1075 2004-05-24 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
1077 * goops.c (compute_getters_n_setters, create_standard_classes,
1078 scm_add_slot): Compute closures by calling scm_i_eval_x on a
1079 lambda expression rather than creating them with scm_closure.
1081 2004-05-22 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
1083 * eval.c (s_macro_keyword, scm_m_set_x): Remove checking for
1084 misplaced syntactic keywords. This will not work unless guile's
1085 defmacro feature is deprecated.
1087 (scm_m_case): Fixed a bug that caused the list of labels to grow
1088 with every case form.
1090 2004-05-19 Kevin Ryde <user42@zip.com.au>
1092 * numbers.c (scm_round_number): For inum and big, just return x. For
1093 real, use scm_round for 2^54-1 etc problems covered there.
1095 * numbers.c (trunc): Remove #define to scm_truncate when the C library
1096 doesn't provide trunc. This was for when `truncate' was done as a
1097 scm_tc7_dsubr, no longer required.
1099 * threads.c (scm_threads_mark_stacks) [SCM_STACK_GROWS_UP]: Correction
1100 to stack marking call, two parameters and no cast on t->base.
1102 2004-05-18 Marius Vollmer <mvo@zagadka.de>
1104 * hashtab.c (rehash_after_gc): Bug fix: properly link the
1105 processed hashtables back into the weak_hashtables list. Thanks
1106 to Bill Schottstaedt!
1108 2004-05-16 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
1110 * eval.c (unmemoize_quote): New static function.
1112 (scm_m_quote, scm_m_atslot_ref, SCM_CEVAL): Changed the byte code
1113 representation of 'quote' and '@slot-ref' to an improper list.
1114 This reduces execution time, the number of cells used to hold the
1115 memoized code, and thus also reduces garbage collection time.
1117 (scm_unmemocopy): Use unmemoize_quote for quote expressions.
1119 (SCM_CEVAL): Changed macro handling to also work with macros that
1120 return improper lists. Added an assertion, that the code returned
1121 by a macro transformer will not lead to cycles in the memoized
1124 2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
1126 No functional change, just rearrangements of functions within the
1129 * eval.c (scm_ilookup, scm_unbound_variable_key,
1130 error_unbound_variable, scm_lookupcar1, scm_lookupcar): Moved to
1131 the definitions used for execution, since that's where they will
1134 2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
1136 * numbers.h (SCM_SLOPPY_FRACTIONP): Removed. It was not used
1137 throughout guile, has not been part of an official release yet,
1138 and the concept of sloppy predicates has never been a good idea.
1140 (SCM_FRACTION_NUMERATOR, SCM_FRACTION_DENOMINATOR,
1141 SCM_FRACTION_SET_NUMERATOR, SCM_FRACTION_SET_DENOMINATOR):
1144 2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
1146 * throw.c (SETJBJMPBUF, SCM_SETJBDFRAME): Add cast to scm_t_bits
1147 to make explicit what happens.
1149 2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
1151 * dynl.c (SET_DYNL_HANDLE): Add cast to scm_t_bits to make
1152 explicit what happens.
1154 * guardians.c (TCONC_IN): Use SCM_SET_CELL_OBJECT_x rather than
1155 SCM_SET_CELL_WORD_x when writing scheme objets to cell elements.
1157 2004-05-11 Marius Vollmer <mvo@zagadka.de>
1159 * scmsigs.c (scm_sigaction_for_thread): Validate that the handler
1160 is indeed a procedure when it isn't a number.
1162 2004-05-10 Marius Vollmer <mvo@zagadka.de>
1164 Convert floating point numbers into strings with an arbitrary
1165 radix. Thanks to Richard Todd!
1167 * numbers.c (FLOBUFLEN): Increase so that radix 2 strings will
1170 (scm_dblprec, fx_per_radix, init_dblprec, init_fx_radix,
1171 number_chars): New, to support variable radices.
1172 (idbl2str): Use above instead of the old base-10 only tables.
1173 (iflo2str): Pass on new RADIX argument to idbl2str.
1174 (scm_number_to_string): Pass radix to iflo2str.
1175 (scm_print_real, scm_print_complex): Explicitly pass radix 10 to
1177 (scm_init_numbers): Call init_dblprec and init_fx_radix for all
1180 2004-05-10 Kevin Ryde <user42@zip.com.au>
1182 * numbers.c (scm_logbit_p): Correction to test above the end of an
1183 inum. Reported by Jan Konecny.
1185 2004-05-06 Marius Vollmer <marius.vollmer@uni-dortmund.de>
1187 * gc.h (scm_t_cell): Fields are now of type SCM instead of
1188 scm_t_bits. Updated all users.
1189 (SCM_GC_CARD_SIZE_MASK): Use SCM_GC_SIZEOF_CARD instead of
1190 duplicating the code.
1191 (SCM_CELL_OBJECT_LOC): New.
1192 (SCM_CARLOC, SCM_CDRLOC): Use it instead of SCM_CELL_WORD_LOC.
1193 (SCM_CELL_WORD_LOC): Moved to "deprecated.h".
1195 * smob.h (SCM_SMOB_DATA_2, SCM_SMOB_DATA_3, SCM_SMOB_FLAGS,
1196 SCM_SET_SMOB_DATA_2, SCM_SET_SMOB_DATA_3, SCM_SET_SMOB_FLAGS,
1197 SCM_SMOB_OBJECT, SCM_SMOB_OBJECT_2, SCM_SMOB_OBJECT_3,
1198 SCM_SET_SMOB_OBJECT, SCM_SET_SMOB_OBJECT_2, SCM_SET_SMOB_OBJECT_3,
1199 SCM_SMOB_OBJECT_LOC, SCM_SMOB_OBJECT_2_LOC,
1200 SCM_SMOB_OBJECT_3_LOC): New.
1201 * smob.c (scm_i_set_smob_flags): New function.
1203 * dynl.c, dynwind.c, eval.h, fluids.h, futures.h, hashtab.h,
1204 hooks.h, keywords.h, macros.h, macros.c, mallocs.c, mallocs.h,
1205 random.h, regex-posix.h, root.h, srcprop.h, srcprop.c, threads.h:
1206 Use SCM_SMOB_* instead of SCM_CELL_* as appropriate. Use
1207 SCM_SMOB_FLAGS and SCM_SET_SMOB_FLAGS instead of accessing the
1208 zeroth word directly. Use SCM_SMOB_PREDICATE as appropriate.
1210 * numbers.h (SCM_I_BIG_MPZ): Use SCM_CELL_OBJECT_LOC instead of
1211 taking the address of SCM_CELL_WORD_1, the latter being no longer
1214 * variable.h (SCM_VARIABLE_LOC): Use SCM_CELL_OBJECT_LOC instead
1215 of casting SCM_CELL_WORD_LOC.
1217 2004-05-02 Kevin Ryde <user42@zip.com.au>
1219 * eval.c (scm_macroexp): Add prototype, since it's not in eval.h under
1220 --disable-deprecated. Reported by Andreas Vögele.
1222 * filesys.c (_POSIX_C_SOURCE): Define to 199506L to get readdir_r (in
1223 particular on HP-UX). Reported by Andreas Vögele.
1225 * list.c (varargs.h): Remove, leave just stdarg.h which is all the
1226 code has support for. Fixes building with AIX cc, which is ansi but
1227 doesn't define __STDC__. Reported by Keith Crane.
1228 (var_start): Remove macro, this variation no longer required.
1229 (scm_list_n): Use va_start directly.
1231 2004-05-01 Kevin Ryde <user42@zip.com.au>
1233 * continuations.c (scm_dynthrow): Use >= instead of SCM_PTR_GE which
1234 is now gone. Reported by Andreas Vögele.
1236 2004-04-28 Kevin Ryde <user42@zip.com.au>
1238 * backtrace.c (display_frame_expr), numbers.c (XDIGIT2UINT,
1239 mem2uinteger, mem2decimal_from_point, mem2ureal): Cast char to int for
1240 ctype.h tests, to avoid warnings from gcc on HP-UX about char as array
1241 subscript. Reported by Andreas Vögele.
1242 Also cast through unsigned char to avoid passing negatives to those
1243 macros if input contains 8-bit values.
1245 * num2integral.i.c (NUM2INTEGRAL): Under non-BIGMPZ_FITSP case,
1246 corrections to range check for signed numbers. Remove
1247 scm_remember_upto_here_1(num) from these checks, since num is used
1248 subsequently anyway.
1250 * num2integral.i.c (NUM2INTEGRAL): Test BIGMPZ_FITSP with "!= 0" to
1251 avoid warning from gcc 3.4. Reported by Hyperdivision.
1253 * numbers.c (scm_bit_extract): Use min instead of MIN.
1254 (MIN): Remove, this conflicts with similar macro defined by limits.h
1255 on HP-UX. Reported by Andreas Vögele.
1257 * stime.c (_POSIX_C_SOURCE): Define to 199506L to get gmtime_r (in
1258 particular on HP-UX). Reported by Andreas Vögele.
1260 * threads.c (scm_threads_mark_stacks): Correction sizet -> size_t.
1261 Reported by Andreas Vögele.
1263 * threads-plugin.h (SCM_MUTEX_MAXSIZE): Increase to 25*sizeof(long),
1264 for the benefit of hpux11 where pthread_mutex_t is 88 bytes. Reported
1267 2004-04-22 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
1269 * eval.c (s_macro_keyword): New static identifier.
1271 (scm_m_define): Change order to first create binding and
1272 evaluating the expression afterwards.
1274 (scm_m_set_x): Memoize complete set! expression. Only leave
1275 symbols if no binding exists at memoization time. Throw error if
1276 assigning to a syntactic keyword.
1278 (lazy_memoize_variable): New function.
1280 (CEVAL): When execution set!, perform lazy memoization if
1281 unmemoized symbol is detected.
1283 * modules.c (module_variable): Return variables with unbound
1286 * tags.h: Fix comment.
1288 2004-04-25 Kevin Ryde <user42@zip.com.au>
1290 * chars.c (scm_char_upcase, scm_char_downcase, scm_c_upcase,
1291 scm_c_downcase): Use ctype.h toupper and tolower. This will be useful
1292 in 8-bit locales, and ensures consistency with char-upper-case? and
1293 char-lower-case? which already use ctype.h.
1294 (scm_c_upcase_table, scm_c_downcase_table, scm_lowers, scm_uppers):
1296 * chars.c, chars.h, init.c (scm_tables_prehistory): Remove.
1298 * socket.c (VALIDATE_INET6): Correction to bignum_in_ipv6_range_p
1299 call. Reported by Hyperdivision.
1301 * threads.c (scm_yield): Correction, actually call scm_thread_yield.
1302 Reported by Hyperdivision.
1304 * unif.c (s_scm_make_uve): Remove unused local variable. Reported by
1307 2004-04-22 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
1309 Hide the implementation of ilocs and isyms in eval.c.
1311 * deprecated.h (SCM_IFRINC, SCM_ICDR, SCM_IFRAME, SCM_IDIST,
1312 SCM_ICDRP), eval.c (SCM_IFRINC, SCM_ICDR, SCM_IFRAME, SCM_IDIST,
1313 SCM_ICDRP), eval.h (SCM_ICDR, SCM_IFRINC, SCM_IFRAME, SCM_IDIST,
1314 SCM_ICDRP): Deprecated and added to deprecated.h. Moved from
1317 * deprecated.c (scm_isymnames), deprecated.h (scm_isymnames,
1318 SCM_ISYMNUM, SCM_ISYMCHARS), eval.c (SCM_ISYMNUM, isymnames,
1319 scm_unmemocopy, CEVAL), print.c (scm_isymnames), tags.h
1320 (SCM_ISYMNUM, scm_isymnames, SCM_ISYMCHARS): Deprecated
1321 scm_isymnames, SCM_ISYMNUM and SCM_ISYMCHARS and added to
1322 deprecated.[hc]. Moved scm_isymnames from print.c to eval.c and
1323 renamed to isymnames. Moved SCM_ISYMNUM from tags.h to eval.c and
1326 * eval.c (scm_i_print_iloc, scm_i_print_isym), eval.h
1327 (scm_i_print_iloc, scm_i_print_isym), print.c (scm_iprin1):
1328 Extracted printing of ilocs and isyms to guile internal functions
1329 scm_i_print_iloc, scm_i_print_isym of eval.c.
1331 2004-04-22 Kevin Ryde <user42@zip.com.au>
1333 * numbers.c (scm_bit_extract): Use SCM_SRS for signed right shift.
1335 * numbers.c (scm_round): Test for x already an integer, to avoid bad
1336 rounding in x+0.5 when x is a big value already an integer. In
1337 certain hardware rounding cases x+0.5 can give an adjacent integer,
1338 leading to that as the result, when we really just wanted x itself.
1340 2004-04-19 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
1342 * eval.c (scm_unmemocopy): Fixed unmemoization of let*.
1344 (deval_args, CEVAL): Minor improvements: Reduced variable scopes,
1345 added const qualifiers, cast intentionally unused expressions to
1346 void for emphasis, improved comment.
1348 2004-04-18 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
1350 * tags.h (scm_tags, scm_tc8_tags, scm_tc9_flag, scm_tc8_flag,
1351 scm_tc8_isym): Renamed scm_tags to scm_tc8_tags. Renamed
1352 scm_tc9_flag to scm_tc8_flag. Introduced new identifier
1353 scm_tc8_isym. Defined tc8-tags relative to scm_tc3_imm24.
1354 Defined the tc8-tag for flags to be 0x04, which will mean that
1355 SCM_BOOL_F will also have the value 0x04 instead of 0x013c. Due
1356 to the reduced number of bits and the simpler bit pattern for
1357 SCM_BOOL_F, certain machines may be able to use more efficient
1358 processor instructions to deal with SCM_BOOL_F.
1360 (SCM_ITAG9, SCM_MAKE_ITAG9, SCM_ITAG9_DATA): Removed. These have
1361 never been defined in a released version, thus no need to
1364 (SCM_IFLAGP, SCM_MAKIFLAG, SCM_IFLAGNUM): Flags now use tc8
1365 instead of tc9 tags.
1367 (SCM_ISYMP, SCM_MAKISYM, SCM_ISYMNUM): Isyms now use tc8 instead
1370 (SCM_MAKSPCSYM): Removed. It is almost impossible that user code
1371 could have used this definition.
1373 (SCM_IM_AND, SCM_IM_BEGIN, SCM_IM_CASE, SCM_IM_COND, SCM_IM_DO,
1374 SCM_IM_IF, SCM_IM_LAMBDA, SCM_IM_LET, SCM_IM_LETSTAR,
1375 SCM_IM_LETREC, SCM_IM_OR, SCM_IM_QUOTE, SCM_IM_SET_X): Now encoded
1376 as isyms, as special isyms don't exist any more.
1378 2004-04-18 Kevin Ryde <user42@zip.com.au>
1380 * filesys.c (scm_readdir): Use readdir_r when available, for thread
1383 * numbers.c (scm_max, scm_min): For big/real, use SCM_SWAP rather than
1384 explicit swapping code.
1386 2004-04-15 Kevin Ryde <user42@zip.com.au>
1388 * cpp_sig_symbols.in: Add SIGSYS.
1390 * list.c (scm_append_x): Use iterative style, to avoid non-tail
1393 * numbers.c (scm_max, scm_min): For inum/frac, frac/inum, big/frac,
1394 frac/big and frac/frac, use scm_less_p for exact comparison.
1396 * numbers.c (scm_gcd): For inum/big, use mpz_gcd_ui by sharing code
1399 * numbers.c (xisinf): Add a comment about solaris 7 lacking isinf.
1401 2004-04-06 Han-Wen Nienhuys <hanwen@xs4all.nl>
1403 * inline.h (scm_cell): use SCM_GC_CELL_WORD for checking tag.
1405 * chars.h (scm_init_chars): change scm_{upcase,downcase} to
1406 scm_c_{up,down}case.
1407 (SCM_MAKE_CHAR): add (unsigned char) cast. This prevents havoc
1408 when hi-bit ASCII is subjected to SCM_MAKE_CHAR().
1410 2004-04-06 Kevin Ryde <user42@zip.com.au>
1412 * numbers.c (scm_ash): Remove stray "}" in docstring.
1414 * numbers.c (scm_make_ratio): For inum/bignum integer detection, use
1415 x==SCM_MOST_NEGATIVE_FIXNUM explicitly, for clarity and to avoid
1416 calling mpz_cmp_ui in most cases.
1418 * numbers.c (scm_quotient, scm_remainder): In inum/big, use mpz_cmp_ui
1419 for big == abs(most-negative-fixnum) special case.
1420 (abs_most_negative_fixnum): Remove, no longer used.
1422 * scmsigs.c (scm_sigaction_for_thread): Correction to signum range
1423 test, avoids SCM_VECTOR_REF outside bounds of signal_handlers on
1424 calling (sigaction NSIG).
1426 * simpos.c (scm_system_star): Fix execargv memory leak, merge parent
1427 and fork error cases to do this.
1429 2004-04-03 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
1431 * eval.c (CEVAL): Don't distinguish between short and long
1432 instructions when dispatching - just always dispatch on the
1433 instruction code, which is common for short and long instructions.
1434 Further, removed unnecessary goto statements and added comment.
1436 2004-04-03 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
1438 * eval.c (scm_unmemocopy): Don't distinguish between short and
1439 long instructions when dispatching - just always dispatch on the
1440 instruction code, which is common for short and long instructions.
1441 Further, removed unnecessary goto statements, fixed indentation
1442 and replaced SCM_IMP predicates by SCM_NULLP.
1444 2004-04-03 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
1446 * eval.c (scm_lookupcar1, CEVAL): Use SCM_ILOCP instead of
1447 comparison with SCM_ILOC00. In CEVAL, eliminate goto-label
1450 2004-03-31 Kevin Ryde <user42@zip.com.au>
1452 * simpos.c: Include <signal.h> for SIG_IGN and friends.
1454 2004-03-29 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
1456 Introduce scm_debug_mode_p as a replacement for scm_debug_mode and
1459 * debug.h (scm_debug_mode_p, scm_debug_mode, SCM_DEBUGGINGP),
1460 eval.c (scm_debug_mode_p): Deprecated scm_debug_mode and
1461 SCM_DEBUGGINGP. Provided scm_debug_mode_p instead, to have one
1462 single interface that also matches the naming conventions.
1463 Probably scm_debug_mode_p should be part of the private interface
1466 * debug.h (scm_debug_mode_p), backtrace.c (display_error_body),
1467 eval.c (SCM_APPLY, scm_trampoline_0, scm_trampoline_1,
1468 scm_trampoline_2): Change uses of scm_debug_mode or SCM_DEBUGGINGP
1469 to scm_debug_mode_p.
1472 Deprecate direct access to scm_ceval, scm_deval and scm_ceval_ptr:
1474 * eval.h (scm_ceval, scm_deval, scm_ceval_ptr), debug.h
1475 (scm_ceval_ptr): Deprecated. Moved declaration of scm_ceval_ptr
1476 from debug.h to eval.h.
1478 * debug.h (SCM_RESET_DEBUG_MODE): Don't access scm_ceval_ptr any
1479 more, just leave it with setting scm_debug_mode_p, which is
1480 equivalent for practical purposes.
1482 * deprecated.h (SCM_XEVAL, SCM_XEVALCAR): Call scm_i_eval_x
1483 instead of *scm_ceval_ptr. Leave all evaluating to scm_i_eval_x.
1485 * gdbint.c (gdb_eval): Call scm_i_eval_x instead of scm_ceval.
1487 * eval.c (ceval, deval, scm_ceval, scm_deval): Made scm_ceval
1488 static and renamed it to ceval throughout. Provide a new exported
1489 but deprecated function scm_ceval as a wrapper for backwards
1490 compatibility. The same is done for the deval/scm_deval pair of
1493 * eval.c (CEVAL, SCM_CEVAL): Renamed SCM_CEVAL to CEVAL
1494 throughout. Defined CEVAL to ceval or deval, based on compilation
1497 * eval.c (SCM_XEVAL, SCM_XEVALCAR): Dispatch on scm_debug_mode_p
1498 to ceval and deval instead of calling *scm_ceval_ptr.
1500 * eval.c (dispatching_eval): New deprecated static function.
1502 * eval.c (scm_ceval_ptr): Initialized to dispatching_eval in order
1503 to emulate its old behaviour as closely as possible.
1506 Change the evaluator such that only expressions for which pair? is
1507 true are passed to CEVAL, and such that all other expressions are
1508 evaluated outside of CEVAL:
1510 * eval.c (EVAL): New, provided in analogy to EVALCAR. Evaluate an
1511 expression that is assumed to be memoized already. All but
1512 expressions of the form '(<form> <form> ...)' are evaluated inline
1513 without calling an evaluator.
1515 * eval.c (SCM_XEVAL, SCM_XEVALCAR, EVALCAR): Evaluate all but
1516 expressions of the form '(<form> <form> ...)' inline without
1517 calling an evaluator.
1519 * eval.c (scm_i_eval_x, scm_i_eval, scm_ceval, scm_deval): Handle
1520 the special case of unmemoized symbols passed on the top level.
1522 * eval.c (CEVAL): Change calls to CEVAL to EVAL, except where it
1523 is known that the expression passed to CEVAL is of the form
1524 '(<form> <form> ...)'. Remove handling of the tc7-objects, since
1525 now it is known that the input expression of CEVAL is a pair.
1527 2004-03-29 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
1529 * eval.c (is_self_quoting_p): New static function.
1531 (scm_m_quote): Use is_self_quoting_p.
1533 (copy_tree): Corrected typo in comment.
1535 2004-03-28 Han-Wen Nienhuys <hanwen@xs4all.nl>
1537 * eval.c (s_scm_copy_tree): idem.
1539 * list.c (s_scm_filter): remove "pointer" from doc string.
1541 * gc.h (SCM_GC_CELL_TYPE): SCM_GC_CELL_TYPE uses SCM_GC_CELL_OBJECT.
1543 * goops.h (SCM_NUMBER_OF_SLOTS): don't SCM_UNPACK the result.
1545 * backtrace.c ("display_backtrace_body"): SCM_PACK before SCM_EQ_P
1546 (display_frame): idem.
1547 (display_backtrace_file_and_line): idem.
1549 * tags.h (SCM_UNPACK): stricter typechecking on SCM_UNPACK
1552 2004-03-26 Kevin Ryde <user42@zip.com.au>
1554 * filesys.c (scm_getcwd, scm_readlink): Avoid memory leak on errors.
1556 * numbers.c (scm_modulo): For inum/big and big/big, remove test of
1557 big==0 since that never occurs.
1559 * numbers.c, numbers.h (scm_modulo_expt): Renamed from
1560 scm_modular_expt, matching scheme level name `modulo-expt'.
1562 * numbers.c (scm_modular_expt): Return a negative remainder for a
1563 negative divisor, the same as `modulo' does.
1565 2004-03-26 Eric Hanchrow <offby1@blarg.net>
1567 * numbers.c, numbers.h (scm_modular_expt): New function.
1569 2004-03-25 Kevin Ryde <user42@zip.com.au>
1571 * numbers.c (scm_min, scm_max): Correction to big/real and real/big,
1572 return inexact as required by r5rs.
1574 2004-03-24 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
1576 * eval.c: Separated some definitions relevant for execution from
1577 the memoization part of the file.
1579 (copy_tree): New static function
1581 (scm_copy_tree): Rewritten to fix two kinds or bugs: First, cyclic
1582 structures are detected now and will lead to an exception instead
1583 of forcing guile to run in an endless loop, using up all the
1584 system's memory. Second, arrays in the cdr of an improper list
1585 are now copied. See the new test cases in eval.test.
1587 2004-03-24 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
1589 * posix.c (scm_gethostname): Make sure len is initialised before
1590 it is used. Restructured to (hopefully) represent possible
1591 configurations more clearly in the code. Added unwind handler.
1593 2004-03-23 Kevin Ryde <user42@zip.com.au>
1595 * posix.c (scm_gethostname): Use sysconf(_SC_HOST_NAME_MAX) and/or
1596 MAXHOSTNAMELEN when available.
1598 2004-03-21 Marius Vollmer <mvo@zagadka.de>
1600 * read.c (skip_scsh_block_comment): Also recognize '\r' as a line
1601 terminator. Rewritten the logic as a state machine, I must have
1602 been doing too much VHDL lately...
1604 * eval.c (scm_ceval, scm_deval): Explicitely evaluate ports to
1605 themselves. Thanks to Han-Wen Nienhuys!
1607 * list.c: Changed docstrings so that they no longer talk about
1608 returning 'pointers' to something.
1610 2004-03-20 Han-Wen Nienhuys <hanwen@xs4all.nl>
1612 * gc.c: remove set_debug_cell_accesses! when
1613 SCM_DEBUG_CELL_ACCESSES is not defined. Scheme source code should
1614 use (if (defined? 'set-debug-cell-accesses!) .. ) to switch on
1615 debugging conditionally.
1617 2004-03-21 Kevin Ryde <user42@zip.com.au>
1619 * stime.c (scm_gmtime): Use gmtime_r when available, for thread safety.
1621 2004-03-20 Kevin Ryde <user42@zip.com.au>
1623 * posix.c (scm_gethostname): Preserve errno across free() call.
1625 2004-03-18 Han-Wen Nienhuys <hanwen@xs4all.nl>

1630 2004-03-14 Kevin Ryde <user42@zip.com.au>
1632 * stime.c: Define _GNU_SOURCE for strptime prototype from glibc.
1633 (strptime): Use HAVE_DECL_STRPTIME for when to give own prototype.
1635 2004-03-07 Kevin Ryde <user42@zip.com.au>
1637 * stime.c (scm_gmtime): Return bd_time->tm_zone when available, rather
1639 (filltime): Make zname parameter "const".
1641 2004-03-03 Mikael Djurfeldt <mdj@chunk.mit.edu>
1643 * threads.c, threads.h (scm_c_scm2thread): New function.
1645 2004-02-29 Kevin Ryde <user42@zip.com.au>
1647 * numbers.c (guile_ieee_init): Use C99 INFINITY and NAN when
1648 available. Test HAVE_DINFINITY and HAVE_DQNAN for those globals, in
1649 particular don't assume "defined (__alpha__) && ! defined (linux)"
1650 means OSF. Remove "SCO" code, which was not really SCO specific and
1651 which John W. Eaton advises should be long past being needed.
1653 * posix.c (scm_execl, scm_execlp, scm_execle): Avoid memory leak under
1656 2004-02-24 Kevin Ryde <user42@zip.com.au>
1658 * posix.c (scm_cuserid): Use a private result buffer, for thread safe.
1660 2004-02-22 Kevin Ryde <user42@zip.com.au>
1662 * numbers.c (scm_max, scm_min): For one arg, dispatch to generic for
1663 complex, same as for two args. (Handle only inum, big, real, frac).
1665 2004-02-21 Kevin Ryde <user42@zip.com.au>
1667 * posix.c (scm_crypt): Use new HAVE_CRYPT.
1668 (<crypt.h>): Remove HAVE_LIBCRYPT condition.
1669 Reported by Andreas Voegele.
1671 2004-02-20 Neil Jerram <neil@ossau.uklinux.net>
1673 * list.c (scm_list_n): Add #if SCM_DEBUG_CELL_ACCESSES_P around
1676 * read.c (scm_lreadparen): Removed.
1677 (scm_lreadparen1): Renamed scm_i_lreadparen.
1679 2004-02-20 Han-Wen Nienhuys <hanwen@xs4all.nl>
1681 * list.c (scm_list_n): validate non-immediate arguments;
1682 this will catch forgotten a SCM_UNDEFINED.
1684 2004-02-18 Marius Vollmer <mvo@zagadka.de>
1686 * gc.h (scm_gc_cells_collected): Removed duplicated declaration.
1687 Thanks to Bill Schottstaedt!
1689 * socket.h (scm_gethost): Removed prototype it is already in
1690 "net_db.h". Thanks to Bill Schottstaedt!
1692 2004-02-18 Kevin Ryde <user42@zip.com.au>
1694 * num2integral.i.c (INTEGRAL2BIG): WORDS_BIGENDIAN not right for word
1695 order parameter to mpz_import, in fact with just one word there's no
1696 order to worry about at all.
1698 * numbers.c (scm_num_eq_p): For real==frac, complex==frac, frac==real
1699 and frac==complex, make an exact comparison rather than converting
1700 with fraction2double.
1702 * posix.c, putenv.c, stime.c (environ): Use _NSGetEnviron in Darwin
1703 shared library, since environ is not directly available there.
1705 * script.c (scm_shell_usage): Print to stdout for --help, per GNU
1708 * stime.c (scm_localtime, scm_gmtime, scm_mktime): Provide a default
1709 errno EINVAL in case localtime and gmtime don't set it.
1710 (scm_mktime, scm_strptime): Forcibly use errno EINVAL for our
1711 SCM_SYSERROR, since mktime and strptime generally don't set errno.
1713 2004-02-16 Kevin Ryde <kevin@swox.se>
1715 * gc-malloc.c (scm_done_malloc, scm_done_free): Allow negative sizes,
1716 which were permitted in the past for these.
1718 * num2float.i.c (NUM2FLOAT): Expand isfinite to !xisinf, as per
1719 previous change to numbers.c.
1721 * script.c (scm_shell_usage): Print bug-guile email address, as per

1726 * unif.c (scm_make_uve): Removed local variable and simplified
1727 code in order to avoid compiler used uninitialized warnings.
1729 * hashtab.c, hashtab.h (scm_hash_map_to_list): Renamed from
1731 (scm_hash_fold): Use scm_call_3 directly in the call to
1732 scm_internal_hash_fold instead of going via fold_proc (which is
1734 (scm_hash_for_each): Use a trampoline +
1735 scm_internal_hash_for_each_handle.
1736 (scm_internal_hash_for_each_handle, scm_hash_for_each_handle): New
1739 2004-02-12 Kevin Ryde <user42@zip.com.au>
1741 * ports.c (scm_port_line): In docstring, note first line is 0.
1742 (scm_set_port_line_x): In docstring, note first line is 0.
1743 (scm_port_column): In docstring, there's no default to current input
1744 port, and remove shared port-line @defun.
1745 (scm_set_port_column_x): In docstring, there's no default to current
1746 input port, note first column is 0, remove shared set-port-line!
1749 * ramap.c (scm_array_fill_x): For fvect and dvect, use scm_num2dbl to
1750 convert args the same way that array-set! does.
1752 * unif.c (scm_make_uve, scm_array_p): Allow fraction 1/3 as prototype
1754 (scm_array_p): Add missing "break"s in switch, fix llvect test look
1755 for "l" not "s", fix dvect to be false for singp(prot) since such a
1757 (scm_array_prototype): Return 1/3 for dvect, rather than 0.33..33.
1758 (exactly_one_third): New variable.
1759 (scm_init_unif): Initialize it.

1768 * read.c (scm_read_opts): New opts `elisp-vectors' and
1771 (scm_lreadr): Use scm_lreadparen1 instead of scm_lreadparen. Make
1772 handling of elisp vector syntax dependent on SCM_ENABLE_ELISP and
1773 `elisp-vectors' option instead of SCM_ELISP_READ_EXTENSIONS.
1774 Allow "\(" and "\)" in strings when SCM_ENABLE_ELISP defined and
1775 `escaped-parens' option set.
1776 (scm_read_token): If elisp vector syntax active, disallow [ and ]
1778 (scm_lreadparen): Rewrite as interface to scm_lreadparen1.
1779 (scm_lreadparen1): New.
1781 * read.h: Remove conditionally compiled last arg to

1787 * eval.c (m_expand_body): remove stray variable new_body.
1789 2004-01-22 Marius Vollmer <mvo@zagadka.de>
1791 * eval.c (m_expand_body): Rewrite the expression in place (by
1792 overwriting FORMS) also when a letrec is constructed, not only
1793 when no definitions are found. Do not return rewritten expression
1794 to emphasize the in-place rewriting. Changed all users.
1796 2004-01-19 Han-Wen Nienhuys <hanwen@xs4all.nl>
1798 * gc.c: add protected_object_count, a number that is dumped from

1816 #{.}#, and all numeric strings specially. Thanks to Paul Jarc!
1818 * guile-snarf.in: Use mkdir to create a unique temporary directory
1819 that we can safely use. Thanks to Stefan Nordhausen!

1823 * dynwind.h, dynwind.c (scm_i_dowinds): Removed 'explicit'
1824 argument since it is always zero now. Changed all callers.
1825 Removed code for handling fluids.
1827 * fluids.c (scm_c_with_fluids): Use frames instead of adding to
1828 the wind chain explicitely. Use scm_c_with_fluid for the common
1829 case of only one fluid.
1830 (scm_with_fluid): New.

1841 scm_begin_frame -> scm_frame_begin,
1842 scm_end_frame -> scm_frame_end,

1845 scm_on_unwind_with_scm -> scm_frame_unwind_with_scm,
1846 scm_on_rewind_with_scm -> scm_frame_rewind_with_scm.
1849 * aync.h, async.c: Did the follwing renamings:
1850 scm_with_blocked_asyncs -> scm_frame_block_asyncs,

1854 * ports.h, ports.c: Did the follwing renamings:
1855 scm_with_current_input_port -> scm_frame_current_input_port,
1856 scm_with_current_output_port -> scm_frame_current_output_port,
1857 scm_with_current_error_port -> scm_frame_current_error_port.
1860 2004-01-07 Kevin Ryde <user42@zip.com.au>
1862 * numbers.c (s_bignum): Remove, not used since gmp bignums.
1863 Reported by Richard Todd.
1865 * threads-plugin.h (SCM_MUTEX_MAXSIZE): Increase to 12*sizeof(long),
1866 for the benefit of powerpc-apple-darwin5.5. Reported by Richard Todd.
1868 * unif.c (scm_aind): Test SCM_CONSP rather than !SCM_NULLP while
1869 traversing the args list, fixes segv if an improper list is given.
1870 Reported by Rouben Rostamian.
1872 2004-01-06 Marius Vollmer <marius.vollmer@uni-dortmund.de>
1874 * ports.c (swap_ports, scm_with_current_foo_port): Do not allocate
1875 swap_data on stack, use a 'malloc obj'.
1877 * fluids.h, fluids.c (scm_make_initial_fluids, scm_copy_fluids,
1878 scm_swap_fluids, scm_swap_fluids_reverse): Renamed to
1879 scm_i_... since they are internal. Changed all uses.
1881 * dynwind.c (frame_print): Removed, use the default printer.
1882 (WINDER_F_MARK, WINDER_MARK_P, winder_mark): New.
1883 (scm_on_unwind_with_scm, scm_on_rewind_with_scm): New. Use above
1884 to protect SCM values.
1886 * dynwind.h (SCM_F_WIND_EXPLICITELY,
1887 SCM_F_WIND_EXPLICITLY): It's "explicitly" not "explicitely", damn.
1889 (scm_on_unwind_with_scm, scm_on_rewind_with_scm): New.
1891 2004-01-05 Marius Vollmer <mvo@zagadka.de>

1902 scm_begin_frame, scm_end_frame, scm_on_unwind, scm_on_rewind):
1904 (scm_dowinds, scm_i_dowinds): scm_dowinds has been renamed to
1905 scm_i_dowinds and extended to handle frames and to invoke a 'turn'
1906 function when the outermost wind point has been reached. The
1907 latter is used to copy a continuation stack at the right time.
1908 scm_dowinds remains available.
1909 (SCM_GUARDSP, SCM_BEFORE_GUARD, SCM_AFTER_GUARD, SCM_GUARD_DATA,
1910 tc16_guard, guards_print): Removed.

1914 part of copy_stack_and_call.
1915 (copy_stack_and_call): Copy the stack after unwinding and before
1917 (scm_dynthrow): Do not call scm_dowinds, this is now done by
1918 copy_stack_and_call.
1920 2004-01-04 Kevin Ryde <user42@zip.com.au>
1922 * numbers.c (scm_less_p): Don't convert frac to float for compares,

1935 * numbers.c (scm_less_p): Remove spurious xisnan from frac+big case.
1937 * numbers.c (scm_make_ratio): Check for numerator equal to
1938 SCM_MOST_NEGATIVE_FIXNUM and bignum denominator the negative of that,
1941 * numbers.c (scm_real_part): Return fraction unchanged rather than
1942 converting to flonum.
1944 2003-11-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
1946 * modules.c (module_variable): Fixed (and thus simplified) the
1947 definition of SCM_BOUND_THING_P to reflect the fact that since
1948 after the 1.4 series of guile, obarrays only hold variable
1951 2003-11-30 Marius Vollmer <mvo@zagadka.de>
1953 * numbers.c (scm_logand): It's "#b...", not "#\b...".
1957 * read.c (scm_lreadr): Signal an error for invalid escape
1958 sequences in strings. Code cleanups too.
1960 * print.c (scm_iprin1): use \xNN hexadecimal sequences when
1961 writing control characters in strings.
1963 2003-11-21 Marius Vollmer <mvo@zagadka.de>
1965 * ports.c (scm_drain_input): Bug fix: only access the port after
1966 checking that it indeed is one.
1968 2003-11-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
1970 * eval.c (s_bad_define): New static identifier.
1972 (m_body): Fixed comment.
1974 (scm_m_define): Don't generate memoized code for definitions that
1975 are not on the top level. As a consequence, no memoized code at
1976 all is generated for definitions any more: Top level definitions
1977 are executed immediately during memoization and internal
1978 definitions are handled separately in m_expand_body.
1980 (scm_unmemocopy, unmemocopy): Removed code for unmemoizing
1981 definitions. Consequently, there is no unmemoizing code any more
1982 that might modify the environment. Thus, the old scm_unmemocopy
1983 is removed and the old unmemocopy is renamed to scm_unmemocopy.
1985 (SCM_CEVAL): The SCM_IM_DEFINE keyword can no longer occur in
1986 memoized code. Call EVALCAR for continuations. Prefer !SCM_NULLP
1987 over SCM_NIMP in places, where the argument is known to be part of

1995 * numbers.c (scm_bit_extract): Use mpz functions, rearrange inum case
1996 to share some shifting.
1998 * numbers.c (scm_integer_expt): Don't mpz_init after scm_i_clonebig or
1999 scm_i_mkbig, since they do so already. Don't mpz_clear a bignum SCM,
2002 2003-11-19 Marius Vollmer <mvo@zagadka.de>
2004 * numbers.c (scm_make_ratio): Rewritten to have a simpler
2005 structure. Previously, not all cases with a negative denominator
2008 * numbers.c (mem2decimal_from_point): use scm_divide instead of
2009 scm_divide2real when forming the fractional part. This allows
2010 "#e1.2" to yield 6/5.
2012 * numbers.c (scm_i_fraction_equalp): Do not treat the return value
2013 of scm_equal_p as a C boolean, use SCM_FALSEP. Previously, all
2014 fractions were equal to each other regardless of value. Ooops.

2069 * gen-scmconfig.c (main): remove public definition of
2070 SCM_SIZEOF___INT64 and SCM_SIZEOF_UNSIGNED___INT64 and add
2071 direct typedef of long_long and ulong_long inside deprecated block
2074 * deprecated.h: move long_long and ulong_long definitions to
2075 gen-scmconfig.c so that we don't need to add SCM_SIZEOF___INT64
2076 and SCM_SIZEOF_UNSIGNED___INT64 to the public namespace.

2485 2003-09-16 Marius Vollmer <mvo@zagadka.de>
2487 * stime.c (scm_current_time): 'time' does not set errno so don't
2488 use SCM_SYSERROR for reporting errors.
2490 2003-09-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
2492 This set of patches eliminates the dependency between the
2493 implementation of evaluator specific memoization codes and special
2494 constants like #f, '() etc. ('flags'), which are not evaluator
2495 specific. The goal is to remove definitions of evaluator
2496 memoization codes completely from the public interface. This will
2497 make it possible to experiment more freely with optimizations of
2498 guile's internal representation of memoized code.
2500 * objects.c (scm_class_of): Eliminate dependency on SCM_ISYMNUM.
2502 * print.c (iflagnames): New array, holding the printed names of
2503 guile's special constants ('flags').
2505 (scm_isymnames): Now holds only the printed names of the
2508 (scm_iprin1): Separate the handling of memoization codes and
2509 guile's special constants.
2511 * tags.h (scm_tc9_flag, SCM_ITAG9, SCM_MAKE_ITAG9, SCM_ITAG9_DATA,
2514 (scm_tc8_char, scm_tc8_iloc, SCM_BOOL_F, SCM_BOOL_T,
2515 SCM_UNDEFINED, SCM_EOF_VAL, SCM_EOL, SCM_UNSPECIFIED, SCM_UNBOUND,
2516 SCM_ELISP_NIL, SCM_IM_DISPATCH, SCM_IM_SLOT_REF,
2517 SCM_IM_SLOT_SET_X, SCM_IM_DELAY, SCM_IM_FUTURE,
2518 SCM_IM_CALL_WITH_VALUES, SCM_IM_NIL_COND, SCM_IM_BIND): Changed
2521 (SCM_IFLAGP): SCM_IFLAGP now only tests for flags.
2523 (SCM_IFLAGP, SCM_MAKIFLAG, SCM_IFLAGNUM): Generalized to use the
2524 tc9 macros and scm_tc9_flag.
2526 2003-09-15 Marius Vollmer <mvo@zagadka.de>
2528 * posix.c (scm_setgroups): Check that the gid list is not too
2529 long. Thanks to Paul Jarc!
2531 2003-09-14 Dirk Herrmann <D.Herrmann@tu-bs.de>
2533 * tags.h: Reduced the number of short instructions from 14 to 13.
2534 The typecode of the former 14th short instruction is now used to
2535 represent long instructions. Changed some comments to reflect
2538 (SCM_MAKISYM): ISYMs get a new tc7 code, namely the one that was
2539 previously used by SCM_IM_DEFINE.
2541 (SCM_IM_DEFINE): Turned into a long instruction.
2543 * eval.c (unmemocopy, SCM_CEVAL): Treat SCM_IM_DEFINE as a long
2546 * eval.c (SCM_CEVAL): Since characters and iflags have now a tc7
2547 code that is separate from all instructions, one level of dispatch
2548 for long instructions can be eliminated.
2550 * print.c (scm_isymnames): Removed some commented code.
2552 2003-09-12 Marius Vollmer <mvo@zagadka.de>
2554 * __scm.h (SCM_FENCE): Use __memory_barrier with the Intel
2557 * hashtab.h (scm_tc16_hashtable): Added "extern" declaration.
2559 * modules.c (scm_module_reverse_lookup): Check that the obarray
2560 really is a hashtable and do nothing if not.
2562 * inline.h: Use "extern inline" only with GCC. Use "static
2565 2003-09-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
2567 * numbers.h (SCM_INEXACTP, SCM_REALP, SCM_COMPLEXP): Removed uses
2568 of SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP.
2570 * numbers.h, deprecated.h (SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP,
2571 SCM_SLOPPY_COMPLEXP): Deprecated and moved from numbers.h to
2574 2003-09-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
2576 * eq.c (scm_eqv_p, scm_equal_p): Removed uses of
2577 SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP.
2579 * eq.c (scm_eqv_p, scm_equal_p): Reordered comparisons from
2580 0.0==some_expression to some_expression==0.0. The latter is
2581 better readable. The former is preferred by some people, since it
2582 leads to a compiler error when confusing == with =. However, when
2583 using gcc, a warning will be issued if in an if-statement an
2584 assigment appears. Since many Guile developers are using gcc,
2585 such errors will not remain unnoticed anyway. We can therefore
2586 focus on better readability.
2588 2003-09-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
2590 * tags.h: Added description of Guile's type system. Removed some
2591 old and misleading comments.
2593 2003-09-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
2595 * unit.c (scm_cvref): Eliminate unnecessary uses of SCM_NIMP,
2596 SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP.
2598 2003-09-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
2600 * numbers.h (SCM_MAKINUM): Define in terms of scm_tc2_int.
2602 (SCM_INEXACTP, SCM_REALP, SCM_COMPLEXP): Define in terms of the
2603 respective SLOPPY macro.
2605 2003-09-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
2607 * eq.c (scm_equal_p): Use SCM_TYP7 to check if an object is of
2608 type string, not SCM_TYP7S.
2610 2003-09-03 Kevin Ryde <user42@zip.com.au>
2612 * numbers.c (scm_lognot): Correction to docstring, ones-complement not
2615 * stime.c (scm_strptime): Add comment about glibc strptime %s and
2616 current timezone requiring SCM_DEFER_INTS.
2618 2003-08-30 Neil Jerram <neil@ossau.uklinux.net>
2620 * script.c (scm_compile_shell_switches): Make -s switch optional
2621 if file to be loaded does not begin with a `-'. (Thanks to Aaron
2622 VanDevender for the patch!)
2624 2003-08-30 Kevin Ryde <user42@zip.com.au>
2626 * numbers.c (scm_lognot): Rewrite using ~ and mpz_com, for directness
2627 and to have non-integer types rejected as per other logical funcs.
2629 2003-08-28 Kevin Ryde <user42@zip.com.au>
2631 * gc.h (scm_remember_upto_here_1): Revise comments on the asm form.
2633 2003-08-23 Kevin Ryde <user42@zip.com.au>
2635 * simpos.c (scm_system): Remove SCM_DEFER_INTS, system() should be
2636 thread safe, and could take a long time too.
2638 2003-08-22 Kevin Ryde <user42@zip.com.au>
2640 * numbers.c (scm_difference): Correction to bignum - negative inum.
2642 2003-08-14 Kevin Ryde <user42@zip.com.au>
2644 * gc.h (scm_remember_upto_here_1, scm_remember_upto_here_2)
2645 [__GNUC__]: Use volatile asm macros rather than a function call.
2646 * gc.c (scm_remember_upto_here_1, scm_remember_upto_here_2): Undefine
2647 macros while defining functions.
2649 * simpos.c (getenv): Use <stdlib.h> for prototype.
2650 (scm_system): In docstring, refer to status:exit-val rather than
2653 2003-08-09 Kevin Ryde <user42@zip.com.au>
2655 * srcprop.c (scm_source_properties): Return plist from hash if it's a
2656 list set by source-properties! rather than an SRCPROPS object,
2658 2003-07-29 Kevin Ryde <user42@zip.com.au>
2660 * properties.c (scm_primitive_property_ref): In docstring, note
2661 parameters to not-found-proc, use hyphens rather than underscores for
2662 that parameter name.
2663 (scm_primitive_property_set_x): In docstring, VAL is the value
2666 2003-07-27 Marius Vollmer <mvo@zagadka.de>
2668 * print.c (scm_print_symbol_name): handle more weird characters by
2669 escaping the symbol name properly. Thanks to Paul Jarc!
2671 * posix.h (scm_setgroups): New prototype.
2672 * posix.c (scm_setgroups): New. Thanks to Paul Jarc!
2673 (scm_getgroups): Handle groups ids that don't fit into a fixnum.
2674 Don't use SCM_WRITABLE_VELTS.
2676 * gc.h (SCM_GC_SET_CELL_BVEC): New.
2677 * gc-card.c (scm_i_init_card_freelist): Use it. Thanks to
2680 * __scm.h (SCM_C_INLINE_KEYWORD): New.
2681 * numbers.c: Use it in place of SCM_C_INLINE so that the code
2682 compiles when SCM_C_INLINE is undefined.
2684 2003-07-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
2686 * __scm.h: Reformulated the architecture and compiler properties
2687 in terms of properties of scm_t_bits and SCM variables rather than
2688 in terms of c standard types. This is since it is not known which
2689 of the standard types scm_t_bits and SCM variables will be defined
2692 2003-07-24 Kevin Ryde <user42@zip.com.au>
2694 * numbers.c (scm_angle): Use scm_flo0 for non-negative inum, bignum
2697 2003-07-18 Kevin Ryde <user42@zip.com.au>
2699 * numbers.c (scm_product): In complex * bignum, correction to
2700 REAL/IMAG fetch, x is the complex, not y.
2702 2003-07-13 Mikael Djurfeldt <djurfeldt@nada.kth.se>
2704 * numbers.c (scm_odd_p, scm_even_p): Bugfix: Treat result of
2705 scm_inf_p test as Scheme values.
2706 (scm_sum): Bugfix: Normalize bignum created from a negative bignum
2707 and a positive inum.
2708 Use GNU indentation style.
2710 2003-07-12 Dirk Herrmann <D.Herrmann@tu-bs.de>
2712 * values.c (scm_values): Build lists of length 1 by using
2713 scm_list_1 instead of using scm_cons.
2715 2003-07-10 Kevin Ryde <user42@zip.com.au>
2717 * deprecation.c (scm_c_issue_deprecation_warning_fmt): Add va_end.
2718 * list.c (scm_list_n): Ditto.
2720 * gc-malloc.c (scm_gc_realloc): Define "ptr" at start of function.
2722 2003-07-08 Matthias Koeppe <mkoeppe@merkur.math.uni-magdeburg.de>
2724 * tags.h (scm_t_bits, scm_t_signed_bits, etc): Avoid solaris empty
2725 defines of INTPTR_MAX and UINTPTR_MAX, combine conditionals for
2726 scm_t_bits and scm_t_signed_bits to avoid any chance of one and not
2727 the other using intptr_t.
2729 2003-07-08 Kevin Ryde <user42@zip.com.au>
2731 * numbers.c (scm_make_polar): Use sincos, when available.
2732 (scm_magnitude): Use hypot.
2734 * ports.c (scm_char_ready_p, scm_peek_char): In docstrings, don't use
2735 @footnote since it doesn't go through to guile-procedures.txt.
2737 * threads.c (scm_call_with_new_thread): In docstring, use "( )"
2738 outside @var to quieten makeinfo, and use @code.
2740 2003-07-06 Han-Wen Nienhuys <hanwen@cs.uu.nl>
2742 * gc-malloc.c (decrease_mtrigger): new function
2743 (increase_mtrigger): new function, separate debug registering and
2744 mtrigger administration.
2745 (scm_gc_realloc): bugfix: do mtrigger administration before the
2746 actual realloc, for the realloc might invalidate a GC-d segment of
2747 memory. Thanks to Sam Hocevar for pointing this out.
2748 (scm_gc_realloc): use scm_malloc_reregister instead of
2749 unregistering and registering in sequence.
2751 2003-07-03 Han-Wen Nienhuys <hanwen@cs.uu.nl>
2753 * __scm.h (SCM_ASSERT): change "else" expansion to "do { } while (0)"
2755 2003-07-02 Han-Wen Nienhuys <hanwen@cs.uu.nl>
2757 * __scm.h (SCM_ASRTGO): add "else" to macro expansions with if
2760 2003-06-29 Marius Vollmer <mvo@zagadka.de>
2762 * deprecated.h (SCM_OPDIRP, scm_fport, scm_option, scm_srcprops,
2763 scm_srcprops_chunk, scm_info_frame, scm_stack, scm_array,
2764 scm_array_dim, SCM_ARRAY_CONTIGUOUS, SCM_FUNC_NAME, SCM_WTA,
2765 RETURN_SCM_WTA, SCM_VALIDATE_NUMBER_COPY,
2766 SCM_VALIDATE_NUMBER_DEF_COPY, SCM_VALIDATE_OPDIR): Re-added from
2767 the release_1_6 branch.
2769 2003-06-25 Stefan Jahn <stefan@lkcc.org>
2771 * continuations.c: Redeclaration of getcontext() via the
2772 __asm__ ("getcontext") directive.
2774 * continuations.h: Include <ucontext.h> instead of
2777 2003-06-21 Kevin Ryde <user42@zip.com.au>
2779 * numbers.c (_GNU_SOURCE): #define, to get C99 things.
2780 (scm_asinh, scm_acosh, scm_atanh, scm_truncate, $asinh, $acosh,
2781 $atanh, truncate): Use C library asinh, acosh, atanh and trunc, when
2783 (scm_inexact_to_exact): Expand isfinite to its definition !xisinf.
2784 (isfinite): Remove, conflicts with C99 isfinite().
2786 2003-06-19 Marius Vollmer <mvo@zagadka.de>
2788 * deprecated.h, deprecated.c (scm_strhash, scm_sym2ovcell_soft,
2789 scm_sym2ovcell, scm_intern_obarray_soft, scm_intern_obarray,
2790 scm_symbol_value0, scm_string_to_obarray_symbol scm_intern_symbol,
2791 scm_unintern_symbol, scm_symbol_binding, scm_symbol_interned_p,
2792 scm_symbol_bound_p, scm_symbol_set_x, scm_gentemp): Re-added from
2793 the release_1_6 branch.
2795 2003-06-14 Stefan Jahn <stefan@lkcc.org>
2797 * threads.h: Redefined scm_getspecific() and scm_setspecific()
2798 to be functions instead of macros.
2800 * threads.c: Conditionalized inclusion of <sys/time.h> and
2802 (scm_getspecific, scm_setspecific): Made these two function
2803 real part of the API.
2805 * posix.c (s_scm_putenv): Added some code to make a
2806 (putenv "FOO="), i.e. setting an empty string, work also on
2807 Win32 systems. Thanks to Kevin Ryde for the proposal.
2809 2003-06-12 Kevin Ryde <user42@zip.com.au>
2811 * posix.c (scm_putenv): Free temporary ptr in mingw unset. Add
2812 freebsd to comment about need to use unsetenv.
2814 2003-06-02 Marius Vollmer <mvo@zagadka.de>
2816 * ports.c (scm_peek_char): Safe the column of the port around the
2817 getc/ungetc calls. Thanks to Dr. Peter Ivanyi!
2819 2003-06-07 Kevin Ryde <user42@zip.com.au>
2821 * tags.h: Use inttypes.h and stdint.h when available, for INTPTR_MAX
2822 and friends required by scm_t_bits setups.
2824 2003-06-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
2826 * tags.h (scm_tc2_int): Added.
2828 * tags.h (scm_tc3_int_1, scm_tc3_int_2): Expressed in terms of
2831 * tags.h (scm_tcs_cons_imcar, scm_tcs_cons_nimcar, scm_tcs_struct,
2832 scm_tcs_closures): Hard coded values replaced by symbolic ones.
2834 2003-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
2836 * eval.c: Partially undid my patch from 2003-05-31. This patch
2837 caused the segfault referenced in the previous changelog entry.
2839 2003-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
2841 * tags.h: Fixed comment about the immediate type code layout.
2843 * eval.c: Fixed handling of non-special instructions. Without
2844 this patch, guile will segfault on (#\0) and similar instructions.
2846 2003-06-05 Kevin Ryde <user42@zip.com.au>
2848 * numbers.c (scm_max, scm_min): For inum, bignum and real, if other
2849 operand is NaN, then return NaN. Also avoid passing NaN to mpz_cmp_d.
2851 * read.c (scm_input_error): Pass arg list parameter to scm_error_scm,
2852 rather than SCM_EOL. Needed by "Unknown # object" case in scm_lreadr.
2854 2003-06-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
2856 * __scm.h, gc-card.c (SCM_DEBUG_DEBUGGER_SUPPORT,
2857 SCM_DEBUG_DEBUGGING_SUPPORT): Renamed macro
2858 SCM_DEBUG_DEBUGGER_SUPPORT to SCM_DEBUG_DEBUGGING_SUPPORT and
2859 generalized it to apply not only to C level functions but also to
2860 scheme level functions.
2862 * debug.c, debug.h, eval.c (make-iloc, scm_make_iloc, iloc?,
2863 scm_iloc_p, dbg-make-iloc, scm_dbg_make_iloc, dbg-iloc?,
2864 scm_dbg_iloc_p): Moved functions scm_make_iloc, scm_iloc_p to
2865 eval.c, made them available under SCM_DEBUG_DEBUGGING_SUPPORT == 1
2866 only and renamed them to scm_dbg_make_iloc, scm_dbg_iloc_p,
2869 * deprecated.h, eval.c, eval.h (SCM_ILOC00, SCM_IDINC,
2870 SCM_IDSTMSK): Deprecated. The macro definitions are moved from
2871 eval.h into eval.c and a copy is placed into deprecated.h.
2873 * eval.c, eval.h (SCM_MAKE_ILOC): Removed from eval.h and placed
2874 into eval.c. This definition was not part of the API in any
2875 officially released version of guile and thus does not need to go
2876 through a phase of deprecation.
2878 2003-06-02 Dirk Herrmann <D.Herrmann@tu-bs.de>
2880 * deprecated.c, deprecated.h, eval.c, eval.h (scm_s_expression,
2881 scm_s_test, scm_s_body, scm_s_bindings, scm_s_variable,
2882 scm_s_clauses, scm_s_formals): Deprecated. In eval.c the
2883 definitions are make static and renamed from scm_s_xxx to s_xxx.
2884 In deprecated.c the original definitions are copied.
2886 * deprecated.h, eval.c, eval (SCM_EVALIM2, SCM_EVALIM, SCM_XEVAL,
2887 SCM_XEVALCAR): Deprecated. The macro definitions are moved from
2888 eval.h into eval.c and a copy (slightly modified to work in user
2889 code) is placed into deprecated.h.
2891 * eval.c: Use the local static s_xxx definitions instead of the
2892 scm_s_xxx definitions throughout.
2894 2003-06-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
2896 This set of patches separates the representation of the cxr family
2897 of functions (car, cdr etc.) from the dsubr family of functions
2898 (i. e. functions that take a double precision floating point
2899 argument). Further, the algorithm for handling the cxr function
2902 * eval.c (SCM_CEVAL, SCM_APPLY, scm_trampoline_1), numbers.c
2903 (scm_asinh, scm_acosh, scm_atanh, scm_truncate, scm_round, floor,
2904 ceil, sqrt, fabs, exp, log, sin, cos, tan, asin, acos, atan, sinh,
2905 cosh, tanh), objects.c (scm_class_of), procprop.c
2906 (scm_i_procedure_arity), ramap.c (scm_array_map_x), tags.h
2907 (scm_tc7_dsubr, scm_tcs_subrs): Introduce scm_tc7_dsubr as new
2908 typecode for the dsubr family of functions.
2910 * ramap.c (ramap_cxr, ramap_dsubr): Renamed ramap_cxr to
2913 * eval.c (SCM_CEVAL, SCM_APPLY, call_cxr_1), pairs.c
2914 (scm_init_pairs): Make use of the (now usable) second cell element
2915 of a scm_tc7_cxr function to implement the cxr family of functions
2918 2003-05-31 Dirk Herrmann <D.Herrmann@tu-bs.de>
2920 * eval.c (SCM_CEVAL, SCM_APPLY, scm_trampoline_0,
2921 scm_trampoline_1, scm_trampoline_2): Postpone error cases to the
2922 end of an if-else-if-sequence of checks.
2924 2003-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
2926 * eval.c (SCM_CEVAL): Improved readability of call-with-values
2927 execution. Generalize apply_closure to apply_proc and use that
2928 for call-with-values.
2930 2003-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
2932 * eval.c (SCM_CEVAL): Avoid one level of indirection when applying
2935 2003-05-30 Stefan Jahn <stefan@lkcc.org>
2937 * posix.c (s_scm_putenv): Use the new HAVE_UNSETENV
2938 appropriately for mingw32 hosts.
2940 * numbers.h: Defining copysign(), isnan() and finite() to
2941 be prefixed by a single '_' for mingw32 hosts.
2943 2003-05-30 Kevin Ryde <user42@zip.com.au>
2945 * numbers.c (z_negative_one): New variable.
2946 (scm_init_numbers): Initialize it.
2947 (scm_logcount): Use it and mpz_hamdist to count zeros for negatives.
2949 2003-05-29 Stefan Jahn <stefan@lkcc.org>
2951 * win32-dirent.c: Use malloc() instead of scm_malloc().
2953 * stime.c (s_scm_strftime): Add a type cast to avoid compiler
2956 * posix.c (s_scm_putenv): Disable use of unsetenv() for the
2959 * modules.c (s_scm_module_import_interface): Renamed local
2960 variable interface to _interface. Seems like 'interface'
2961 is a special compiler directive for the mingw32 compiler.
2963 * mkstemp.c: Provide prototype to avoid compiler warning.
2965 * load.c (s_scm_search_path): Fixed absolute and relative
2966 path detections for native Windows platforms.
2968 * gc.h, threads.h: Export some more symbols using SCM_API (necessary
2969 to build on mingw32).
2971 * gc-freelist.c ("s_scm_map_free_list",
2972 "s_scm_gc_set_debug_check_freelist_x"): Fixed use of FUNC_NAME.
2974 * fports.c (fport_fill_input): Disable use of
2975 fport_wait_for_input() on Win32 platforms.
2977 * filesys.c (s_scm_basename): Fixed __MINGW32__ code.
2979 * Makefile.am: Modified some rules for cross compiling.
2981 2003-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2983 * eval.c (SCM_CEVAL): In case of an application, all checks for a
2984 proper function object and the correct number of arguments are now
2985 performed in the application part of SCM_CEVAL.
2987 (scm_badformalsp): Removed.
2989 2003-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>

3092 * numbers.c (scm_integer_length): On negative bignums, adjust
3093 mpz_sizeinbase to account for it looking at absolute value where we
3094 want ones-complement.
3096 * numbers.c (scm_gcd): In bignum/inum, don't pass yy==0 to mpz_gcd_ui
3097 since we're only using the ulong return value, and x might not fit.
3099 2003-05-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
3101 * eval.c, eval.h, read.c, read.h (scm_sym_dot): Moved from eval to

3117 The purpose of this patch is to make guile's internal memoizers
3118 distinguishable from memoizing macros created on the scheme level
3119 or from user provided primitive memoizing macros. The reason is,
3120 that the internal memoizers are the only ones that are allowed to
3121 transform their scheme input into memoizer byte code, while all
3122 other memoizing macros may only transform scheme code into new
3125 To achieve this, a new macro type 'builtin-macro!' is introduced.
3126 Currently, 'builtin-macro!'s are handled as memoizing macros, but
3127 this will change when the memoizer and executor are separated.
3129 * macros.[ch] (scm_i_makbimacro): New.
3131 * macros.h (SCM_BUILTIN_MACRO_P): New.
3133 * macros.c (macro_print, scm_macro_type): Support builtin-macro!s.

3136 primitive builtin-macros now.
3138 * eval.c (scm_macroexp, SCM_CEVAL): Make sure the primitive
3139 builtin-macros are handled equally to memoizing macros.
3141 2003-05-04 Marius Vollmer <mvo@zagadka.de>
3143 * throw.c (scm_ithrow): Remove "asm volatile" hack. It used to
3144 work around a bug in GCC 2.95.2 but is now a bug in itself.
3146 2003-05-02 Marius Vollmer <mvo@zagadka.de>
3148 * deprecated.h (scm_rstate, scm_rng, SCM_SLOPPY_CONSP,

3171 macro was introduced in anticipation of GOOPS method compilation
3174 * goops.c: Removed binding of @dispatch.
3176 2003-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
3178 * eval.c, goops.c (@dispatch, @slot-ref, @slot-set!): Move the
3179 instructions that bind the macros on the scheme level back to
3180 goops.c in order to make sure again that the bindings go into the
3181 (oop goops) module and are not visible from the outside.
3183 2003-04-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
3185 * eval.c: Non functional change: Separated R5RS and non-R5RS
3186 macros into different sections of the file and ordered the
3187 memoizers alphabetically.

3202 scm_m_atslot_set_x, scm_m_atdispatch): Move the declarations and
3203 definitions of the special goops memoizers from goops.[ch] to
3204 eval.[ch]. Hmm... it seems that scm_m_atdispatch is not used

3228 This set of patches contains no functional changes, only debatable
3229 minor stylistic ones. Still, in order to prepare a patch between
3230 my local copy and the CVS version, I decided to submit the changes
3231 below. Then, the patch will hopefully only contain relevant
3234 * eval.c (iqq): Added const specifier.
3236 * eval.c (scm_trampoline_0, scm_trampoline_1, scm_trampoline_2):
3237 Use NULL instead of 0 to indicate that a pointer is returned.
3238 Removed some misleading 'fall through' comments.

3246 * eval.h (SCM_ENTER_FRAME_HDLR, SCM_APPLY_FRAME_HDLR,
3247 SCM_EXIT_FRAME_HDLR): Use SCM_PACK to convert data to a SCM value
3248 rather than casting to SCM.
3250 2003-04-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
3252 * sort.c, pairs.h: Removed unnecessary includes.
3254 2003-04-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
3256 * sort.c: Replaced hand-made trampline code by the new official
3257 mechanism from eval.c. This fixes a segfault in the new test file

3263 scm_merge_vector_step, scm_stable_sort_x, scm_stable_sort,
3264 scm_sort_list_x, scm_sort_list): Use trampoline mechanism from

3268 cmp_fun_t): Removed.
3270 (compare_function): Added.
3272 * sort.c (quicksort, SWAP, stack_node): Replaced pointer
3273 arithmetics with index arithmetics. Changed quicksort to work on
3274 an array of SCM values instead of an array of characters. Avoid
3275 bytewise copying of SCM elements. Avoid allocating memory on the
3276 stack with alloca. Fixed some comments.
3278 2003-04-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
3280 * eval.c (EXTEND_ENV): Eliminated.
3282 (unmemocopy, SCM_CEVAL, SCM_APPLY): Use SCM_EXTEND_ENV instead of

3290 compiling with SCM_DEBUG==1 by moving definition behind prototype.
3292 * gc.card.c (scm_dbg_t_list_cell, scm_dbg_t_double_cell,

3295 scm_gc_marked_p, scm_gc_get_card, scm_gc_get_bvec): Fixed
3296 functions such that they check if the object is a non-immediate.
3297 Further, renamed identifiers to use the scm_dbg_ prefix and made
3298 their inclusion into the lib dependent of the
3299 SCM_DEBUG_DEBUGGER_SUPPORT compile time option.
3301 2003-04-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
3303 * __scm.h: Fixed comment about the SCM_DEBUG_TYPING_STRICTNESS
3306 2003-04-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
3308 * list.c (scm_ilength, scm_last_pair), unif.c (l2ra): Prefer
3309 !SCM_CONSP over SCM_NCONSP. Now, guile itself does not include
3310 any calls to SCM_NCONSP any more.
3312 * unif.c (l2ra): Eliminate redundant check.
3314 2003-04-21 Dirk Herrmann <D.Herrmann@tu-bs.de>

3317 scm_array_map_x), unif.c (l2ra): Prefer !SCM_NULLP over
3318 SCM_NNULLP. Now, guile itself does not include any calls to

3325 other expressions into an expression of their own.
3327 2003-04-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
3329 * goops.c (TEST_CHANGE_CLASS, scm_sys_initialize_object): Don't
3330 compare SCM values with !=.

3334 * eval.c, eval.h, evalext.c, evalext.h (scm_sym_setter,
3335 scm_m_generalized_set_x, scm_init_evalext): Move the declaration
3336 and definition of the memoizer for the generalized set! macro from
3337 evalext.[ch] to eval.[ch]. Use the SCM_SYNTAX snarfer macro to
3338 define the macro object.
3340 * eval.c, eval.h (s_set_x, scm_s_set_x, scm_m_set_x,
3341 scm_m_generalized_set_x): Since now scm_s_set_x is only used in
3342 eval.c, it is made static and renamed to s_set_x.

3347 2003-04-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
3349 * eval.c, root.h (scm_undefineds, SCM_NUM_PROTECTS, undefineds,
3350 scm_init_eval): Made scm_undefineds static in eval.c, renamed it
3351 to undefineds and registered the object as a permanent object.
3353 * eval.c, eval.h (scm_f_apply, scm_init_eval): Made scm_f_apply
3354 static in eval.c, renamed it to f_apply and registered the object
3355 as a permanent object.
3357 2003-04-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
3359 * eval.c (SCM_BIT7, SCM_BIT8, unmemocopy, SCM_CEVAL): Renamed
3360 file-local macro SCM_BIT8 to SCM_BIT7, which is more appropriate.
3362 2003-04-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
3364 * numbers.c (scm_logtest): Fixed argument bug in the call to
3365 mpz_and, which showed up when compiling with SCM_DEBUG defined.

3416 oop/goops/active-slot.scm.)
3418 2003-04-14 Rob Browning <rlb@defaultvalue.org>
3420 * tags.h: scm_t_intptr should have been intptr_t.
3422 2003-04-13 Rob Browning <rlb@defaultvalue.org>
3424 * __scm.h (SCM_FLUSH_REGISTER_WINDOWS): don't just rely on "sparc"
3426 #if defined (sparc) || defined (__sparc__) || defined (__sparc)
3427 as gc_os_dep.c suggests is appropriate.
3429 * goops.c (prep_hashsets): make static to match prototype.
3430 (scm_sym_args): SCM_SYMBOL -> SCM_GLOBAL_SYMBOL. Thanks to Albert
3433 * c-tokenize.lex: remove trailing comma from enum. Thanks to

3463 * random.c: #include gmp.h.
3464 (scm_c_random_bignum): normalize result on return.
3466 * init.c: #include gmp.h.
3468 * numbers.h: remove the gmp.h #include (not needed now).
3470 * posix.h: change occurences of "id" to something else so we don't
3471 cause trouble when included via objective-c (can't hurt, might
3472 help). Still have usage in debug.h, though.
3474 2003-04-06 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3476 * random.c (scm_c_random_bignum): Don't generate a random number
3477 equal to m (the second argument of scm_c_random_bignum); only
3478 generate numbers in the range 0 <= r < m.
3479 (scm_c_default_rstate): Use SCM_VARIABLE_REF to access
3480 scm_var_random_state.
3482 * num2integral.i.c (INTEGRAL2BIG): Put negation of n inside then

3999 * list.c, list.h (scm_filter, scm_filter_x): New functions.
4001 * modules.c (scm_module_import_interface): New function.
4003 * goops.c, goops.h (scm_class_accessor_method): Renamed from
4005 (scm_class_accessor): New class.
4007 2003-03-06 Mikael Djurfeldt <djurfeldt@nada.kth.se>
4009 * goops.c (scm_primitive_generic_generic): Enable primitive
4010 generic if not enabled.
4011 (scm_sys_goops_loaded): Setup unextended primitive generics.
4013 * goops.c, goops.h (scm_c_extend_primitive_generic): New function.
4015 * snarf.h (SCM_PRIMITIVE_GENERIC, SCM_PRIMITIVE_GENERIC_1): New
4018 * numbers.c (scm_abs): Use SCM_PRIMITIVE_GENERIC. (This is only a
4019 testing example. All uses of SCM_GPROC should be converted.)
4021 * procprop.c (scm_stand_in_scm_proc): Use scm_assq instead of
4024 * eq.c (scm_equal_p): Turned into a primitive generic.
4026 2003-02-27 Rob Browning <rlb@defaultvalue.org>
4028 * Makefile.am (scmconfig.h): new target -- generate file from
4030 (modinclude_HEADERS): remove version.h.
4031 (nodist_modinclude_HEADERS): add version.h.
4033 2003-02-24 Mikael Djurfeldt <djurfeldt@nada.kth.se>
4035 This fixes a serious GC bug, introduced during the latest
4036 reorganization of the GC, which disabled freeing of structs and
4039 * struct.c (scm_struct_prehistory): Init scm_i_structs_to_free to
4041 (scm_struct_prehistory): Move scm_free_structs to
4042 scm_before_mark_c_hook.
4044 * gc-card.c (sweep_card): Check that we haven't swept structs on
4045 this card before. That can happen if scm_i_sweep_all_segments has
4046 been called from some other place than scm_igc.
4048 2003-02-19 Mikael Djurfeldt <djurfeldt@nada.kth.se>
4050 * environments.c (DEFAULT_OBARRAY_SIZE): Changed from 137 to 31
4051 (since hash tables now adapt their size).
4053 * modules.c (scm_modules_prehistory): Changed from 2001 to 1533
4054 (current number of prehistory bindings; hashtable code will select
4055 a prime which is greater than this value).
4057 * symbols.c (scm_symbols_prehistory): Changed from 1009 to 2139
4058 (current number of initial symbols).
4060 * properties.c (scm_init_properties): Don't specify size of
4061 scm_properties_whash.
4063 * objprop.c (scm_init_objprop): Don't specify size of
4066 * keywords.c (scm_init_keywords): Don't specify a hash table size.
4068 * hooks.c (scm_c_hook_add): Fixed bug in append mode.
4070 The following changes introduce the use of resizable hash tables
4071 throughout Guile. It also renames the old *-hash-table* functions
4072 to *-alist-vector* and places them, together with the rest of the
4073 weak vector support, in the module (ice-9 weak-vector). We should
4074 probably introduce a new, better, API for weak references, for
4075 example "weak pairs" a la MIT-Scheme. (In Chez scheme, they even
4076 look like and are used like ordinary pairs.)
4078 * environments.c (obarray_enter, obarray_retrieve, obarray_remove,
4079 leaf_environment_fold, obarray_remove_all): Use hashtable
4082 * gc.c (scm_init_storage): Moved hook initialization to
4083 scm_storage_prehistory.
4084 (scm_storage_prehistory): New function.
4085 (scm_igc): Added commentary about placement of
4086 scm_after_sweep_c_hook.
4088 * gc-mark.c (scm_mark_all): Use hashtable accessors.
4089 (scm_gc_mark_dependencies): Use SCM_WVECT_WEAK_KEY_P and
4090 SCM_WVECT_WEAK_VALUE_P.
4092 * hashtab.c, hashtab.h (scm_hash_for_each, scm_hash_map): New
4094 (scm_vector_to_hash_table, scm_c_make_resizing_hash_table):
4096 (scm_make_weak_key_hash_table, scm_make_weak_value_hash_table,
4097 scm_make_doubly_weak_hash_table): Moved here from weaks.c.
4099 * init.c (scm_init_guile_1): Removed call to scm_init_weaks; Added
4100 calls to scm_storage_prehistory and scm_hashtab_prehistory.
4102 * modules.c (module-reverse-lookup): Use hashtable accessors.
4104 * symbols.c, symbols.h (scm_i_hash_symbol): New function.
4106 * weaks.c, weaks.h (scm_make_weak_key_alist_vector,
4107 scm_make_weak_value_alist_vector,
4108 scm_make_doubly_weak_alist_vector): New functions.
4110 * weaks.c (scm_init_weaks_builtins): New function.
4112 * weaks.h (SCM_WVECTF_WEAK_KEY, SCM_WVECTF_WEAK_VALUE,
4113 SCM_WVECTF_NOSCAN, SCM_WVECT_WEAK_KEY_P, SCM_WVECT_WEAK_VALUE_P,
4114 SCM_WVECT_NOSCAN_P): New macros.
4116 * weaks.c (scm_scan_weak_vectors): Use SCM_WVECT_WEAK_KEY_P
4117 and SCM_WVECT_WEAK_VALUE_P.
4119 * weaks.c, weaks.h (scm_i_allocate_weak_vector): Renamed from
4120 allocate_weak_vector and exported.
4122 2003-02-13 Mikael Djurfeldt <djurfeldt@nada.kth.se>
4124 * hashtab.c: Undid thread safety. (We decided that it's better to
4125 let the user explicitly protect the tables (or not) according what
4126 is suitable for the application.)
4128 2003-02-12 Mikael Djurfeldt <djurfeldt@nada.kth.se>
4130 * hashtab.c (scm_hash_fn_remove_x, scm_internal_hash_fold): Made
4131 thread safe and handle resizing tables.
4132 (scm_ihashx, scm_sloppy_assx, scm_delx_x): Removed
4133 SCM_DEFER/ALLOW_INTS.
4135 2003-02-11 Mikael Djurfeldt <djurfeldt@nada.kth.se>
4137 * hashtab.c (scm_vector_to_hash_table,
4138 scm_c_make_resizing_hash_table, scm_make_hash_table): New
4140 (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x): Made thread
4141 safe and handle resizing tables.
4143 * weaks.c (scm_make_weak_key_hash_table,
4144 scm_make_weak_value_hash_table, scm_make_doubly_weak_hash_table):
4145 Size argument made optional. Return resizable table if not
4148 2003-02-10 Mikael Djurfeldt <djurfeldt@nada.kth.se>
4150 * eval.c (scm_trampoline_0, scm_trampoline_1, scm_trampoline_2):
4151 Fixed formals tests for closures. (Thanks to Kevin Ryde.)
4153 2003-02-05 Mikael Djurfeldt <djurfeldt@nada.kth.se>
4155 * debug.c (scm_procedure_source): Handle all objects for which
4156 procedure? is #t. (Thanks to Bill Schottstaedt.)
4158 2003-01-23 Mikael Djurfeldt <djurfeldt@nada.kth.se>
4160 * futures.c (mark_futures): Don't need to mark data of recycled
4162 (scan_futures, cleanup_undead): Be smarter about marking
4163 futures---avoid unnecessary passes through future lists.
4165 * futures.h, futures.c: New files; Introduced recycling of
4166 futures. For fine-grained threading this lifts performance to
4167 another level. We can now use parallelization in inner loops of
4168 Guile programs without impossible overhead.
4170 * threads.h, threads.c: Moved futures to their own file.
4172 * Makefile.am (libguile_la_SOURCES): Added futures.c.
4173 (DOT_X_FILES): Added futures.x.
4174 (DOT_DOC_FILES): Added futures.doc.

4177 * threads.c, threads.h (scm_i_create_thread): Renamed from
4178 create_thread and made global.
4180 * futures.c (scm_make_future): New procedure.
4182 * eval.c: #include "libguile/futures.h".
4184 * init.c: #include "futures.h"
4185 (scm_init_guile_1): Call scm_init_futures.
4187 * stime.c (SCM_TIME_UNITS_PER_SECOND): Renamed from CLKTCK.
4189 * stime.h (SCM_TIME_UNITS_PER_SECOND): Definition moved here.
4191 * eval.c, eval.h (scm_trampoline_0, scm_i_call_closure_0): New
4194 * eval.c (scm_trampoline_1): Fixed arguments test for closures.
4196 2003-01-22 Mikael Djurfeldt <djurfeldt@nada.kth.se>
4198 * threads.c (create_thread): Don't unwind dynwind chain of parent
4199 thread before creation. Just start the new thread with an empty
4202 2003-01-20 Mikael Djurfeldt <djurfeldt@nada.kth.se>
4204 * evalext.c, evalext.h (scm_self_evaluating_p): New function.
4206 2003-01-10 Mikael Djurfeldt <djurfeldt@nada.kth.se>
4208 * threads.c (scm_timed_wait_condition_variable): Support timed
4209 waiting also for simple condition variables.
4211 * goops.c (TEST_CHANGE_CLASS): Use scm_change_object_class instead
4212 of calling the procedure change-object-class.
4214 2003-01-09 Mikael Djurfeldt <djurfeldt@nada.kth.se>
4216 * ramap.c (scm_ramapc): Typo in error message.
4218 2003-01-08 Mikael Djurfeldt <djurfeldt@nada.kth.se>
4220 * goops.c (scm_sys_prep_layout_x): Bugfix: Only create layout for
4221 slots with instance allocation.
4223 * goops.c, goops.h (scm_class_extended_generic_with_setter): New
4225 (scm_compute_applicable_methods): Use scm_generic_function_methods.
4227 * goops.c (scm_generic_function_methods): Support extended
4230 2002-12-29 Mikael Djurfeldt <djurfeldt@nada.kth.se>
4232 * eval.c (unmemocopy): Bugfix: scm_sym_delay --> scm_sym_future.
4233 Thanks to Neil for pointing this out!
4235 2002-12-29 Neil Jerram <neil@ossau.uklinux.net>
4237 * lang.h: Remove declarations matching definitions removed from
4238 lang.c (just below).
4240 2002-12-28 Neil Jerram <neil@ossau.uklinux.net>
4242 * lang.c (scm_nil_cons, scm_nil_car, scm_nil_cdr, scm_null,
4243 scm_m_while, scm_nil_eq): Remove definitions that were superfluous
4244 and already commented out.
4246 * read.h (scm_lreadparen), read.c (scm_lreadr, scm_read_token,
4247 scm_lreadparen): Support reading vectors with Elisp syntax if
4248 SCM_ELISP_READ_EXTENSIONS is defined. (SCM_ELISP_READ_EXTENSIONS
4249 is not currently defined, and there isn't even a configure switch
4252 2002-12-26 Marius Vollmer <mvo@zagadka.ping.de>
4254 * Makefile.am (c-tokenize.o): Refer to source via $< so that vpath
4256 (EXTRA_DIST): Added version.h.in.
4258 2002-12-21 Mikael Djurfeldt <djurfeldt@nada.kth.se>
4260 This change makes it possible for one thread to do lazy sweeping
4261 while other threads are running. Now only the mark phase need to
4262 have all threads asleep. We should look further into this issue.
4263 Presently, I've put the locking of scm_i_sweep_mutex at
4264 "conservative" places due to my current lack of knowledge about
4265 the garbage collector. Please feel free to restrict these regions
4266 further to allow for maximal parallelism!
4268 * gc.c, gc.h (scm_i_sweep_mutex): New mutex.
4270 * gc.c (scm_gc_for_newcell), gc-malloc.c (scm_realloc,
4271 scm_gc_register_collectable_memory): Substitute locking of
4272 scm_i_sweep_mutex for calls to scm_i_thread_put_to_sleep.
4273 (scm_igc): Lock sweep mutex here instead of in callers; Calls to
4274 scm_i_thread_put_to_sleep/scm_i_thread_wake_up used to demarkate
4275 the single-thread section (which now only contains the mark
4277 (scm_gc): Don't lock sweeo mutex here since scm_igc locks it;
4278 Removed SCM_DEFER/ALLOW_INTS. Simply call scm_igc directly.
4280 * threads.c (gc_section_mutex): Removed.
4282 2002-12-19 Mikael Djurfeldt <mdj@kvast.blakulla.net>
4284 * threads.c (create_thread): Clear parent field in root state in
4285 order not to unnecessarily remember dead threads.
4287 * eval.c (call_subr2o_1, call_lsubr2_2): New functions.
4288 (scm_trampoline_1, scm_trampoline_2): Use them.
4290 2002-12-18 Mikael Djurfeldt <mdj@kvast.blakulla.net>
4292 Partial introduction of real plugin interface.
4294 * Makefile.am (modinclude_HEADERS): Added threads-plugin.h.
4295 (EXTRA_DIST): Added threads-plugin.c.
4297 * threads-plugin.h, threads-plugin.c: New files.
4299 * threads.h: #include "libguile/threads-plugin.h".
4301 * threads.c: #include "libguile/threads-plugin.c".
4303 * pthread-threads.c: Temporarily remove debugging functions.
4305 * threads.c, threads.h (scm_yield): Added back.
4307 2002-12-18 Mikael Djurfeldt <mdj@kvast.blakulla.net>
4309 * threads.c (really_launch): Detach before unlocking
4310 thread_admin_mutex in order not to risk being joined.
4311 (scm_i_thread_put_to_sleep, scm_i_thread_wake_up): Keep
4312 thread_admin_mutex locked during GC.
4314 * pthread-threads.c, pthread-threads.h: Improvements to debugging
4317 2002-12-16 Mikael Djurfeldt <mdj@kvast.blakulla.net>
4319 * pthread-threads.c, pthread-threads.h (SCM_DEBUG_THREADS): Added
4320 support for debugging mutex operations.
4322 * threads.c (scm_thread): Removed filed joining_threads.
4323 (thread_print): Print thread number as well as address of thread
4325 (scm_join_thread): Bugfix.
4326 (scm_lock_mutex, scm_try_mutex, scm_unlock_mutex,
4327 scm_timed_wait_condition_variable, scm_signal_condition_variable,
4328 scm_broadcast_condition_variable): Use the low-level API.
4329 (scm_all_threads): Return copy of thread list (to prevent
4330 unintended destruction).
4331 (scm_threads_prehistory): Initialize heap_mutex of fake thread.
4333 * pthread-threads.c, pthread-threads.h, threads.c: Fixes to
4334 pthread "native" recursive mutex support.
4336 2002-12-15 Mikael Djurfeldt <djurfeldt@nada.kth.se>
4338 * __scm.h (SCM_DEFER_INTS, SCM_ALLOW_INTS): New definitions.
4339 Simply lock a thread C API recursive mutex.
4340 (SCM_NONREC_CRITICAL_SECTION_START,
4341 SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START,
4342 SCM_REC_CRITICAL_SECTION_END): Removed.
4344 * eval.c: Replaced SOURCE_SECTION_START / SOURCE_SECTION_END with
4345 direct calls to scm_rec_mutex_lock / unlock around the three calls
4346 to scm_m_expand_body.
4348 * eval.c, eval.h (promise_free): New function.
4349 (scm_force): Rewritten; Now thread-safe; Removed
4350 SCM_DEFER/ALLOW_INTS.
4352 * pthread-threads.h: Added partially implemented plugin interface
4353 for recursive mutexes. These are, for now, only intended to be
4354 used internally within the Guile implementation.
4356 * pthread-threads.c: New file.
4358 * threads.c: Conditionally #include "pthread-threads.c".
4360 * eval.c, eval.h (scm_makprom, scm_force): Rewritten to be
4363 * snarf.h (SCM_MUTEX, SCM_GLOBAL_MUTEX, SCM_REC_MUTEX,
4364 SCM_GLOBAL_REC_MUTEX): New macros.
4366 * eval.c, threads.c, threads.h, snarf.h: Rewrote critical section
4367 macros---use mutexes instead.
4369 * tags.h (SCM_IM_FUTURE): New tag.
4371 * eval.c (scm_m_future): New primitive macro.
4372 (SCM_CEVAL): Support futures.
4373 (unmemocopy): Support unmemoization of futures.
4375 * print.c (scm_isymnames): Name of future isym.
4377 * version.c: Unmade some changes to my private copy that got
4378 committed by mistake.
4380 2002-12-11 Mikael Djurfeldt <mdj@kvast.blakulla.net>
4382 * gc-malloc.c, gc.h, init.c: Reverted gc-malloc change of
4385 * gc.c (scm_igc): Don't call scm_i_thread_invalidate_freelists.
4387 * gc.c (scm_gc_sweep): Call it here instead, which is a more
4390 * threads.c (create_thread): Remember root object until the handle
4391 of the new thread is on all_threads list.
4393 * root.c (scm_make_root): Moved copying of fluids until after
4394 creation of root handle so that the fluids are GC protected. Also
4395 removed the critical section.
4397 2002-12-10 Mikael Djurfeldt <mdj@kvast.blakulla.net>
4399 * gc-malloc.c, gc.h (scm_gc_malloc_prehistory): New function.
4401 * gc-malloc.c (malloc_mutex): New mutex.
4402 (scm_gc_malloc_prehistory): Initialize it.
4403 (scm_realloc): Serialize call to realloc
4404 (scm_calloc): Same for calloc.
4405 Thanks to Wolfgang Jaehrling!
4406 (Now we have to make sure all calls to malloc/realloc are made
4407 through scm_malloc.)
4409 * init.c (scm_init_guile_1): Call scm_gc_malloc_prehistory.
4411 * threads.c (really_launch): Release heap (to prevent deadlock).
4412 (create_thread): Release heap before locking thread admin mutex.
4414 2002-12-10 Mikael Djurfeldt <mdj@kvast.blakulla.net>
4416 * threads.c (scm_i_thread_invalidate_freelists): New
4419 * gc.c (scm_igc): Call scm_i_thread_invalidate_freelists.
4421 * modules.c (scm_export): Inserted a return statement.
4423 2002-12-10 Han-Wen Nienhuys <hanwen@cs.uu.nl>
4425 * modules.c (scm_export): new function
4427 * gc-card.c: add a note about malloc()/free() overhead.
4429 2002-12-10 Mikael Djurfeldt <mdj@kvast.blakulla.net>
4431 * Makefile.am (c-tokenize.$(OBJEXT)): Don't look for c-tokenize.c
4434 2002-12-10 Mikael Djurfeldt <djurfeldt@nada.kth.se>
4436 These changes remove scm_ints_disabled (which hasn't has any
4437 effect in Guile for quite some time).
4439 * async.c, error.h (scm_ints_disabled): Removed.
4441 * gc.c (scm_gc_for_newcell), init.c (scm_init_guile_1),
4442 root.c (scm_internal_cwdr), gdbint.c (SCM_BEGIN_FOREIGN_BLOCK,
4443 SCM_END_FOREIGN_BLOCK): Don't touch scm_ints_disabled.
4444 (old_ints): Removed.
4446 * __scm.h (SCM_DEFER_INTS, SCM_ALLOW_INTS): Define as a recursive
4448 (SCM_REDEFER_INTS, SCM_ALLOW_INTS): Define as SCM_DEFER_INTS and
4451 2002-12-09 Mikael Djurfeldt <djurfeldt@nada.kth.se>
4453 * threads.c (scm_mutex_lock, scm_cond_wait, scm_cond_timedwait):
4454 Removed accidental #if 0 around these functions.
4456 These changes are the start of support for preemptive
4457 multithreading. Marius and I have agreed that I commit this code
4458 into the repository although it isn't thoroughly tested and surely
4459 introduces many bugs. The bugs should only be exposed when using
4460 threads, though. Signalling and error handling for threads is
4461 very likely broken. Work on making the implementation cleaner and
4462 more efficient is needed.
4464 * __scm.h (SCM_ALLOW_INTS_ONLY): Removed.
4465 (SCM_NONREC_CRITICAL_SECTION_START,
4466 SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START,
4467 SCM_REC_CRITICAL_SECTION_END): New macros.
4468 (SCM_CRITICAL_SECTION_START/END): Defined here.
4470 * eval.c: Insert SOURCE_SECTION_START / SOURCE_SECTION_END around
4471 the three calls to scm_m_expand_body.
4473 * gc.h: #include "libguile/pthread-threads.h";
4474 (SCM_FREELIST_CREATE, SCM_FREELIST_LOC): New macros.
4476 * gc.c (scm_i_freelist, scm_i_freelist2): Defined to be of type
4479 * gc.c, gc-freelist.c, inline.h: Use SCM_FREELIST_LOC for freelist
4482 * gc-freelist.c (scm_gc_init_freelist): Create freelist keys.
4484 * gc-freelist.c, threads.c (really_launch): Use
4485 SCM_FREELIST_CREATE.
4487 * gc-malloc.c (scm_realloc, scm_gc_register_collectable_memory):
4489 * gc.c (scm_i_expensive_validation_check, scm_gc,
4490 scm_gc_for_newcell): Put threads to sleep before doing GC-related
4491 heap administration so that those pieces of code are executed
4492 single-threaded. We might consider rewriting these code sections
4493 in terms of a "call_gc_code_singly_threaded" construct instead of
4494 calling the pair of scm_i_thread_put_to_sleep () and
4495 scm_i_thread_wake_up (). Also, we would want to have as many of
4496 these sections eleminated.
4498 * init.c (scm_init_guile_1): Call scm_threads_prehistory.
4500 * inline.h: #include "libguile/threads.h"
4502 * pthread-threads.h: Macros now conform more closely to the
4503 pthreads interface. Some of them now take a second argument.
4505 * threads.c, threads.h: Many changes.
4507 2002-12-09 Mikael Djurfeldt <djurfeldt@nada.kth.se>
4509 * Makefile.am (version.h): Changed $^ --> $< in rule for
4512 2002-12-08 Rob Browning <rlb@defaultvalue.org>
4514 * version.h.in (SCM_MICRO_VERSION): use @--@ substitution now.
4515 (SCM_MINOR_VERSION): use @--@ substitution now.
4516 (SCM_MICRO_VERSION): use @--@ substitution now.
4517 (scm_effective_version): new function prototype.
4519 * version.c (scm_effective_version): new function, also add
4522 * Makefile.am (schemelibdir): VERSION -> GUILE_EFFECTIVE_VERSION.
4523 (libpath.h): use GUILE_EFFECTIVE_VERSION to compute
4525 (version.h): generate this here rather than configure.in. This
4526 approach tracks source edits better (i.e. more immediately).
4527 Might be worth considering for other .in files too.
4529 2002-12-02 Marius Vollmer <mvo@zagadka.ping.de>
4531 Reorganized thread package selection. A thread package now only
4532 implements a small set of pthread like functions and Guile
4533 implements the rest on top of that. Guile's implementation is
4534 what the "coop-pthreads" package has been previously. Support for
4535 "coop" threads has been removed until I get time to add it again.

4574 The following change makes it possible to move procedure
4575 application dispatch outside inner loops. The motivation was
4576 clean implementation of efficient replacements of R5RS primitives
4579 The semantics is clear: scm_trampoline_N returns an optimized
4580 version of scm_call_N (or NULL if the procedure isn't applicable
4583 Applying the optimization to map and for-each increases efficiency
4584 noticeably. For example, (map abs ls) is 8 times faster than

4640 * coop-pthreads.c, coop-pthreads.h: scm_internal_select should be
4641 part of the API, otherwise it's difficult to write Guile
4642 extensions using non-blocking I/O => moved #include
4643 "libguile/iselect.h" from coop-pthreads.c --> coop-pthreads.h.

5042 2002-09-24 Gary Houston <ghouston@arglist.com>
5044 * inline.h (scm_double_cell): prevent reordering of statements
5045 with any following code (for GCC 3 strict-aliasing).
5046 * numbers.c (scm_make_real), num2float.i.c (FLOAT2NUM): removed
5047 the earlier version of the reordering prevention.
5049 2002-09-19 Han-Wen Nienhuys <hanwen@cs.uu.nl>

5074 * struct.h: change scm_structs_to_free to scm_i_structs_to_free
5076 * gc-malloc.c (scm_gc_register_collectable_memory): use floats;
5077 these won't ever wrap around with high memory usage. Thanks to
5078 Sven Hartrumpf for finding this.
5080 * gc-freelist.c: include <stdio.h>
5082 * gc-malloc.c: add DEBUGINFO for mtrigger GCs.
5084 2002-09-01 Marius Vollmer <mvo@zagadka.ping.de>
5086 * vectors.h (SCM_VECTOR_REF): New.
5088 * snarf.h (SCM_DEFINE_PUBLIC): New.
5090 2002-08-30 Marius Vollmer <mvo@zagadka.ping.de>
5092 * socket.c (scm_addr_vector): Added size of address to arguments.
5093 Use it to avoid accessing a non-existent path in a sockaddr_un.
5094 Changed all callers.
5096 2002-08-29 Han-Wen Nienhuys <hanwen@cs.uu.nl>
5098 * gc.h: remove DOUBLECELL card flags.
5100 * gc-malloc.c (scm_calloc): try to use calloc() before calling
5103 * gc-segment.c (scm_i_initialize_heap_segment_data): remove card
5104 init loop; handle this from scm_init_card_freelist()
5106 * gc-card.c (scm_init_card_freelist): init bit vector here.
5108 * numbers.c (scm_make_real): prevent reordering of statements

5117 * script.c (scm_compile_shell_switches): Added "2002" to Copyright
5118 years. Thanks to Martin Grabmüller!
5120 2002-08-25 Han-Wen Nienhuys <hanwen@cs.uu.nl>
5122 * gc-segment.c (scm_i_get_new_heap_segment): use float in stead of
5123 unsigned numbers for computing minimum heap increment. This
5124 prevents weird results when a a negative minimum increment is
5127 2002-08-24 Marius Vollmer <mvo@zagadka.ping.de>
5129 * gc_os_dep.c: When we have __libc_stack_end, use that directly
5130 instead of the old tricks.
5132 * guile-snarf.in: Do not expect the input file to be the first
5133 argument after the optional "-o" option, just pass everything to
5134 the pre-processor without extracting the input file name.
5136 2002-08-23 Han-Wen Nienhuys <hanwen@cs.uu.nl>
5138 * gc-segment.c (scm_i_get_new_heap_segment): Oops. We want segment
5139 length *at* least SCM_MIN_HEAP_SEG_SIZE, not at most.
5141 2002-08-22 Han-Wen Nienhuys <hanwen@cs.uu.nl>
5143 * gc.h, gc.c: make scm_cells_allocated unsigned again. Thanks to
5144 Bill Schottstaedt for the bug report
5146 2002-08-20 Marius Vollmer <mvo@zagadka.ping.de>
5148 * print.c (scm_iprin1): Print primitives generics always as
5149 "primitive-generic" even when they have no primitive methods yet.
5151 2002-08-17 Gary Houston <ghouston@arglist.com>
5153 * coop.c (coop_create): removed bogus 2nd argument in scm_malloc
5156 2002-08-17 Han-Wen Nienhuys <hanwen@cs.uu.nl>
5158 * ports.c (scm_add_to_port_table): small bugfix.
5160 * mallocs.c (scm_malloc_obj): use scm_gc_malloc in stead of
5163 * gc-segment.c (scm_i_get_new_heap_segment): remove cluster cruft:
5164 only use SCM_MIN_HEAP_SEG_SIZE.
5166 * ports.c (scm_add_to_port_table): add backwards compatibility
5169 * ports.h: use scm_i_ prefix for port table and port table size.
5171 2002-08-15 Mikael Djurfeldt <mdj@linnaeus>
5173 * vports.c (scm_make_soft_port): Initialize pt variable.
5175 2002-08-13 Marius Vollmer <mvo@zagadka.ping.de>
5177 * strports.h (scm_c_eval_string_in_module,
5178 scm_eval_string_in_module): New prototypes.
5179 * strports.c (scm_eval_string_in_module): New, but use
5180 "eval-string" as the Scheme name and make second parameter
5182 (scm_eval_string): Implement using scm_eval_string_in_module.
5183 (scm_c_eval_string_in_module): New.
5184 Thanks to Ralf Mattes for the suggestion!
5186 2002-08-09 Han-Wen Nienhuys <hanwen@cs.uu.nl>
5188 * gc-card.c ("sweep_card"): remove SCM_MISC_ERROR messages: print
5191 * gc-mark.c ("scm_gc_mark_dependencies"): idem.
5193 * ports.c ("scm_new_port_table_entry"): return a boxed SCM in
5194 stead of scm_t_port*. The function now takes a tag argument.
5196 2002-08-08 Han-Wen Nienhuys <hanwen@cs.uu.nl>
5198 * gc.h: add scm_debug_cells_gc_interval to public interface
5200 * gc-card.c ("sweep_card"): set scm_gc_running while sweeping.
5202 * gc.c (scm_i_expensive_validation_check): separate expensive
5203 validation checks from cheap ones.
5205 2002-08-06 Han-Wen Nienhuys <hanwen@cs.uu.nl>
5207 * read.c (scm_input_error): new function: give meaningful error
5208 messages, and throw read-error
5210 * gc-malloc.c (scm_calloc): add scm_calloc.
5212 2002-08-05 Han-Wen Nienhuys <hanwen@cs.uu.nl>
5214 * tags.h: remove GC bits documentation from the tags table.
5216 * read.c (INPUT_ERROR): Prepare for file:line:column error
5217 messages for errors in scm_lreadr() and friends.
5219 2002-08-04 Han-Wen Nienhuys <hanwen@cs.uu.nl>
5221 * gc-malloc.c (scm_malloc): use scm_realloc() (simplifies
5223 (scm_gc_calloc): new function
5225 2002-08-04 Han-Wen Nienhuys <hanwen@cs.uu.nl>
5227 * ports.c (scm_new_port_table_entry): init port entry to 0
5230 * ports.c (scm_new_port_table_entry): change function from
5231 scm_add_to_port_table. This prevents cells with null-pointers from
5232 being exposed to GC.
5234 * vports.c (scm_make_soft_port) strports.c (scm_mkstrport),
5235 fports.c (scm_fdes_to_port): Use scm_new_port_table_entry().
5237 * gc.c (scm_gc_stats): add cell-yield and malloc-yield statistic
5240 * numbers.c (big2str): return "0" for 0 iso. ""
5242 * gc-segment.c, gc-malloc.c gc-mark.c, gc-freelist.c, gc-card.c,
5243 private-gc.h: new file
5245 * gc.c: completely revised and cleaned up the GC. It now uses lazy
5246 sweeping. More documentation in workbook/newgc.text
5248 2002-07-25 Marius Vollmer <marius.vollmer@uni-dortmund.de>
5250 * random.c (rstate_free): Return zero.
5252 2002-07-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
5254 * environments.c (remove_key_from_alist): Removed.
5256 (obarray_remove): Simplified.
5258 2002-07-24 Stefan Jahn <stefan@lkcc.org>
5260 * continuations.h: ia64: Include <signal.h> before
5263 2002-07-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
5265 * modules.c (scm_sym2var): Don't compare SCM values with ==.
5267 2002-07-21 Han-Wen Nienhuys <hanwen@cs.uu.nl>
5269 * goops.c (scm_compute_applicable_methods): use
5270 scm_remember_upto_here_1 iso scm_remember_upto_here
5272 * macros.c: include deprecation.h
5274 * vectors.c (scm_vector_move_right_x): remove side effect in
5276 (scm_vector_move_left_x): idem.
5278 * net_db.c, posix.c, socket.c: variable naming: change ans to
5281 * sort.c (scm_merge_vector_x): accept vector as argument
5282 iso. SCM*. This is needed for full GC correctness.
5284 * gc.h: undo previous undocumented changes related to #ifdef
5287 2002-07-20 Han-Wen Nienhuys <hanwen@cs.uu.nl>
5289 * *.c: add space after commas everywhere.
5291 * *.c: use SCM_VECTOR_SET everywhere, where a vector is written.
5292 Document cases where SCM_WRITABLE_VELTS() is used.
5294 * vectors.h (SCM_VELTS): prepare for write barrier, and let
5295 SCM_VELTS() return a const pointer
5296 (SCM_VECTOR_SET): add macro.
5298 2002-07-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
5300 * eval.c (SCM_CEVAL), macros.c (macro_print, scm_makmacro,
5301 scm_sym_macro, scm_macro_type), macros.h (scm_makmacro):
5302 Deprecated the special kind of built-in dynamic syntax transformer
5303 that was inaccurately named "macro". Note: The built-in syntax
5304 transformers that are named "mmacro" or "memoizing-macro" still
5305 exist, and it is these which come much closer to what one would
5308 2002-07-13 Neil Jerram <neil@ossau.uklinux.net>
5310 * eval.c (unmemocopy): Fix for
5311 1001-local-eval-error-backtrace-segfaults (unmemoization crash
5312 with internal definitions and local-eval).
5314 2002-07-12 Gary Houston <ghouston@arglist.com>
5316 * dynl.c: Don't define stub procedures if DYNAMIC_LINKING is not
5317 defined. They don't do anything useful, especially since the
5318 only case where DYNAMIC_LINKING is undefined seems to be
5319 when --with-modules=no is given to configure, which is basically
5320 requesting that the "dynamic linking module" be omitted.
5322 * Makefile.am (libguile_la_SOURCES): move dynl.c from
5323 libguile_la_SOURCES to EXTRA_libguile_la_SOURCES.
5325 * extensions.c (load_extension): check DYNAMIC_LINKING for
5327 * init.c (scm_init_guile_1): check DYNAMIC_LINKING for
5328 scm_init_dynamic_linking.
5330 2002-07-10 Marius Vollmer <mvo@zagadka.ping.de>
5332 * guile.c, iselect.h, net_db.c, posix.c, socket.c: No need to
5333 check for Cygwin when including <winsock2.h>, this is already
5334 check for by configure. Thus, revert change from 2002-07-07.
5336 2002-07-10 Gary Houston <ghouston@arglist.com>
5338 * eq.c: include <string.h>
5339 * dynl.c: docstring editing.
5341 2002-07-09 Gary Houston <ghouston@arglist.com>
5343 * dynl.c (scm_dynamic_call): docstring editing.
5345 2002-07-08 Rob Browning <rlb@defaultvalue.org>
5347 * gc_os_dep.c: HURD fixes.
5349 2002-07-07 Marius Vollmer <mvo@zagadka.ping.de>
5351 Crosscompiling and Cygwin fixes by Jan Nieuwenhuizen. Thanks!
5353 * Makefile.am: Override default rule for c-tokenize.$(OBJECT);
5354 this should be compiled for BUILD host.
5355 Override default rule for
5356 guile_filter_doc_snarfage$(EEXECT); this should run on BUILD host.
5357 Add missing $(EXEEXT) to guile_filter_doc_snarfage invocation.
5358 (snarf2checkedtexi): Use GUILE_FOR_BUILD instead of preinstguile.
5360 * guile.c, iselect.h, net_db.c, posix.c, socket.c: Do not include
5361 <winsock2.h> on Cygwin even when we have it.
5363 2002-07-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
5365 * __scm.h (SCM_CAUTIOUS), eval.c (scm_eval_args, deval_args,
5366 SCM_CEVAL): Removed compile time option SCM_CAUTIOUS to clean up
5367 the code. Full number of arguments checking of closures is
5368 mandatory now. However, the option to disable the checking has
5369 most probably not been used anyway.
5371 2002-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
5373 * __scm.h (SCM_RECKLESS), backtrace.c (SCM_ASSERT), debug.c
5374 (scm_debug_options), eval.c (scm_lookupcar, scm_lookupcar1,
5375 scm_badargsp, SCM_CEVAL, SCM_APPLY, scm_map, scm_for_each),
5376 feature.c (scm_init_feature), gsubr.c (scm_gsubr_apply), numbers.c
5377 (scm_logand, scm_logior, scm_logxor, scm_i_dbl2big), srcprop.c
5378 (scm_source_properties, scm_set_source_properties_x,
5379 scm_source_property): Removed compile time option SCM_RECKLESS to
5380 clean up the code. Full number of arguments checking of closures
5381 is mandatory now. However, the option to disable the checking has
5382 most probably not been used anyway.
5384 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
5385 scm_source_property): Use !SCM_CONSP instead of SCM_NCONSP.
5387 2002-06-30 Gary Houston <ghouston@arglist.com>
5389 * dynl.c: Removed all SCM_DEFER_INTS/SCM_ALLOW_INTS, which won't
5390 do anything useful. Added a comment about need for a mutex if
5391 pre-emptive threading is supported.
5393 * posix.c (scm_convert_exec_args), dynl.c
5394 (scm_make_argv_from_stringlist): static procs: 1) renamed both to
5395 allocate_string_pointers. 2) simplified: don't reallocate the
5396 strings, just make an array of pointers 3) avoid memory leaks on
5397 error 4) let the procedure report errors in its own name.
5398 Consequences: 1) the procedures now assume that SCM strings are
5399 nul-terminated, which should always be the case. 2) Since strings
5400 are not reallocated, it's now possible for strings passed to
5401 dynamic-args-call to be mutated.
5403 2002-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
5405 * __scm.h, eval.c, eval.h: Removed compile time option
5406 MEMOIZE_LOCALS to clean up the code. Now, caching of local
5407 variable positions during memoization is mandatory. However, the
5408 option to disable the caching has most probably not been used
5411 2002-06-18 Marius Vollmer <mvo@zagadka.ping.de>
5413 * print.c (scm_simple_format): Print missing part of format before
5414 ~% control. Thanks to Daniel Skarda!
5416 2002-06-01 Marius Vollmer <mvo@zagadka.ping.de>
5418 * mkstemp.c: Added exception notice to license statement.
5420 2002-05-22 Marius Vollmer <mvo@zagadka.ping.de>
5422 * numbers.c (mem2ureal): When returning an inexact zero, make sure
5423 it is represented as a floating point value so that we can change
5426 From John W. Eaton <jwe@bevo.che.wisc.edu>
5428 * numbers.c (idbl2str): Don't omit sign when printing negative zero.
5430 2002-05-14 Thien-Thi Nguyen <ttn@giblet.glug.org>
5432 * gc_os_dep.c: For I386/OPENBSD, allow for `__i386__'
5433 in addition to `i386'. Thanks to Dale P. Smith.
5435 2002-05-08 Marius Vollmer <mvo@zagadka.ping.de>
5437 * eq.c (real_eqv): New.
5438 (scm_eqv_p): Use it when comparing reals and complexes.
5440 * numbers.c: Include <string.h>, for strncmp.
5441 (mem2complex): Do not create negative NaNs.
5442 (scm_leq_p, scm_geq_p): Explicitely return #f when comparing a
5444 (scm_inexact_to_exact): Signal error when converting a NaN.
5446 2002-05-06 Marius Vollmer <mvo@zagadka.ping.de>
5448 * posix.c (scm_putenv): Handle removing variables explicitely by
5453 * numbers.h: Conditionally include floatingpoint.h, ieeefp.h, and
5454 nan.h. Provide declarations for scm_inf_p, scm_nan_p, scn_inf,
5456 * numbers.c: [SCO && ! HAVE_ISNAN] (isnan): New function.
5457 [SCO && ! HAVE_ISINF] (isinf): New function.
5458 (xisinf, xisnan): New functions.
5460 (isfinite): Define in terms of xisinf.
5461 (scm_inf_p, scm_nan_p): New functions.
5462 (guile_Inf, guile_NaN): New file-scope vars.
5463 (guile_ieee_init): New function.
5464 (scm_inf, scm_nan): New functions.
5465 (idbl2str): Handle Inf and NaN. Remove funny label and
5466 corresponding gotos.
5467 (ALLOW_DIVIDE_BY_ZERO): New macro.
5468 (scm_divide): Allow division by zero to occur if
5469 ALLOW_DIVIDE_BY_ZERO is defined.
5470 Handle bignums and ints as special cases.
5472 Additional stuff by me:
5474 numbers.c (mem2ureal): Recognize "inf.0" and "nan.xxx".
5475 (scm_even_p, scm_odd_p): Treat infinity as even and odd.
5476 (iflo2str): Don't output a '+' for negative numbers or for Inf and
5477 NaN. They will provide their own sign.
5478 (scm_divide): Only allow divides by inexact zeros. Dividing by
5479 exact zeros still signals an errors.
5481 2002-04-22 Thien-Thi Nguyen <ttn@giblet.glug.org>
5483 * goops.h (scm_slot_exists_p): Rename from scm_slots_exists_p.
5484 * goops.c (scm_slot_exists_p): Rename from scm_slots_exists_p.
5485 (scm_slot_exists_p): Rename from scm_slots_exists_p.
5486 Thanks to Andreas Rottmann.
5488 2002-04-20 Gary Houston <ghouston@arglist.com>
5490 * removal of unused fields in root state (thanks to Christopher
5491 Cramer for pointing out the disuse.)
5492 * root.h (scm_root_state): removed def_inp, def_outp, def_errp.
5493 (scm_def_inp, scm_def_outp, scm_def_errp): removed.
5495 * root.c (root_mark): don't mark them.
5496 (scm_make_root): don't set them to #f.
5497 * init.c (scm_init_standard_ports): don't initialise with the
5500 2002-04-17 Marius Vollmer <mvo@zagadka.ping.de>
5502 * Makefile.am (EXTRA_DIST): Added cpp_err_symbols.c and
5505 2002-04-16 Marius Vollmer <mvo@zagadka.ping.de>
5507 * guile-snarf.in: Do not clean input file. This would write to
5508 the $(srcdir) during a VPATH build, which is not allowed. It also
5509 isn't needed since it only works when an output filename has been
5510 specified and in that case we don't need to clean the input file
5511 because the output file will already exist.
5513 2002-03-31 Marius Vollmer <mvo@zagadka.ping.de>
5515 * guile-snarf: Install the trap for removing $cleanfile only when
5516 the value of $cleanfile is actually known.
5518 2002-04-10 Rob Browning <rlb@defaultvalue.org>
5520 * .cvsignore: add versiondat.h and *.c.clean.c.
5522 2002-03-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
5524 * srcprop.[ch] (scm_c_source_property_breakpoint_p): New
5525 function, replaces macro SRCBRKP.
5527 (SRCBRKP): Deprecated.
5529 * eval.c (SCM_CEVAL): Replaced use of SRCBRKP by call to
5530 scm_c_source_property_breakpoint_p. Removed some use of arg1 as
5533 2002-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
5535 * debug.h, eval.c: Deprecated CHECK_ENTRY, CHECK_APPLY and
5536 CHECK_EXIT and removed all references to them.
5538 2002-03-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
5540 * debug.h (scm_ready_p, debug_print): Removed declarations.
5542 * eval.c (EVALCELLCAR): Removed.
5544 (SCM_CEVAL): Eliminated label loopnoap. Removed side-effecting
5545 operation from condition.
5547 2002-03-24 Marius Vollmer <mvo@zagadka.ping.de>
5549 * guile-snarf.in: When the output filename is "-", write to
5550 stdout. When no "-o" option is given, use "-" as the output
5551 filename (i.e., stdout). Only 'clean' the inputfile or remove the
5552 output file on error when the output file name is not "-". Define
5553 the preprocessor macro SCM_MAGIC_SNARFER while snarfing.
5555 * Makefile.am (.c.x): Pass "-o $@" to guile-snarf.
5557 2002-03-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
5559 * eval.c (SCM_CEVAL, SCM_APPLY): Eliminated labels wrongnumargs
5560 and the corresponding goto statements. Removed redundant code.
5562 2002-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
5564 * eval.c (SCM_CEVAL): Minimized scope of variable arg2.
5565 Eliminated redundant SCM_IMP check. Exlined call to EVALCAR.
5566 Re-enabled handing of rpsubrs and asubrs.
5568 2002-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
5570 * eval.c (SIDEVAL): Removed.
5572 (SCM_CEVAL): Minimized scope of variable orig_sym. Eliminated
5573 goto-labels cdrxnoap, cdrxbegin and nontoplevel_cdrxnoap. Changed
5574 argument checking order for set! to locals, variables and symbols.
5575 Improvements to control structure. Removed some uses of arg1 and

5695 variables. Introduced temporary variables with hopefully
5696 descriptive names for clarification. Replaced SCM_N?IMP by a more

5718 of SCM_MAX_FRAME_SIZE as a bit mask; it isn't used like this.
5720 * eval.c (SCM_CEVAL): Don't store scm_debug_eframe_size in
5721 debug.status. It isn't needed, and it can overflow the bits

6051 2002-01-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
6053 * eval.c: Removed outdated references to "everr". Improved some
6056 (scm_deval_args, deval_args): Renamed scm_deval_args to
6057 deval_args, since it is not part of the interface.
6059 (SCM_CEVAL): Added (maybe somewhat verbose) comment. Avoid to
6060 use references to debug.vect[0] before it exists. Add parentheses
6061 to switch statement.
6063 * goops.h: Added local emacs variables.
6065 2002-01-10 Dirk Herrmann <D.Herrmann@tu-bs.de>

6146 signal handlers are allowed to divert the flow of control. Call
6147 scm_system_async_mark_from_signal_handler instead of
6148 scm_system_async_mark.
6151 Deprecated SCM_NEWCELL and SCM_NEWCELL2. Added scm_alloc_cell and
6152 scm_alloc_double_cell in their place.
6154 * gc.h (SCM_GC_SET_ALLOCATED, scm_debug_newcell,
6155 scm_debug_newcell2, scm_tc16_allocated): Removed from header.

6188 * numbers.c (scm_divide): Fix more division by zero errors.
6190 2001-11-21 Gary Houston <ghouston@arglist.com>
6192 * Makefile.am (OMIT_DEPENDENCIES): removed, since it seems to be
6193 obsolete. autogen.sh says:
6194 invalid unused variable name: `OMIT_DEPENDENCIES'
6196 2001-11-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
6198 * numbers.c (scm_divide): Fix (/ 0). Thanks to Keith Wright for

6216 M$-Windows compiler. Include some pieces of code (protoent and
6217 servent interface) protected by HAVE_* macros when using a
6218 native M$-Windows compiler.
6220 2001-11-20 Marius Vollmer <mvo@zagadka.ping.de>
6222 * modules.c (scm_c_export): Do nothing when the first argument is
6223 already the terminating NULL. Thanks to Han-Wen Nienhuys!

6241 (SCM_MINOR_VERSION): renamed from SCM_GUILE_MINOR_VERSION.
6242 (SCM_MICRO_VERSION): renamed from SCM_GUILE_MICRO_VERSION.
6244 2001-11-18 Neil Jerram <neil@ossau.uklinux.net>
6246 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
6247 Rewrite docstrings without reference to substring-move-left/right,
6248 since the latter no longer exist.
6250 2001-11-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
6252 * eval.c: Removed bogus comment about acros.
6254 (scm_unmemocar): Use !SCM_CONSP instead of SCM_IMP.
6255 Minimize scope of local variable. Eliminate dependency on
6256 macro DEBUG_EXTENSIONS.
6258 (s_splicing): New error message string.
6260 (scm_m_body): Issue 'bad body' message rather than 'missing
6261 expression' message.
6263 (scm_m_quote): Eliminate unnecessary copying.
6265 (scm_m_lambda, scm_m_letstar, scm_m_letrec, scm_m_let): Leave the
6266 checking of the body to scm_m_body.
6268 (scm_m_do): Move comment to function header. Rename arg1 to
6269 binding. Made the code a bit easier to read.
6273 (iqq): Added a comment. Changed the depth parameter to
6274 unsigned. Use size_t for vector lengths. Make sure vector object
6275 is gc protected as long as its contents are read. Add some syntax
6276 checks. Get rid of unnecessary SCM_IMP test. Clean up the
6277 control structure a bit.
6279 (scm_m_delay): Added comment about the implementation of
6282 (scm_m_define): Add comment about guile's currying define
6283 syntax. Renamed 'proc' to 'name'. Eliminate dependency on macro
6284 DEBUG_EXTENSIONS. Simplified code a bit. Eliminate SICP code.
6286 (scm_m_letrec1): Removed. Part of the functionality is taken
6287 over by the new function 'transform_bindings'.
6289 (transform_bindings): New function. Takes over some of the
6290 functionality of removed function 'scm_m_letrec1', namely to split
6291 a list of bindings into a reversed list of variables and a list of
6294 (scm_m_letrec): Call 'transform_bindings'.
6296 (scm_m_let): Minimized scope of local variables. Renamed 'proc'
6297 to 'temp' and 'arg1' to 'binding'. Eliminated redundant SCM_NIMP
6298 test. Use 'transform_bindings'. Fixed scoping error with named
6299 let (Thanks to Aubrey Jaffer for reporting the bug and to Neil
6300 Jerram for suggesting the fix). Cleaned up the control structure
6303 (scm_m_expand_body): Use 'transform_bindings'. Eliminated
6304 unnecessary consing. Eliminated unnecessary
6305 SCM_DEFER/ALLOW_INTS.
6307 (SCM_CEVAL): Un-obfuscated some loops.
6309 2001-11-16 Neil Jerram <neil@ossau.uklinux.net>
6311 * gc.h (scm_unhash_name): Old declaration removed.
6313 * eval.c (s_scm_eval): Change @var{primitive-eval} to
6314 @code{primitive-eval}.
6316 * feature.c, vectors.c, net_db.c, unif.c, weaks.c, struct.c,
6317 version.c, alist.c, ports.c, ramap.c, unif.c, strings.c, list.c:
6318 Change @deffnx lines in docstrings to say {Scheme Procedure}
6319 rather than primitive or procedure.
6321 * posix.c (scm_execl), filesys.c (scm_close), unif.c
6322 (scm_array_set_x, scm_array_contents, scm_uniform_array_read_x,
6323 scm_bit_set_star_x, scm_bit_invert_x), ramap.c (scm_array_fill_x,
6324 scm_array_for_each, scm_array_index_map_x), vectors.c (scm_vector,
6325 scm_make_vector, scm_vector_to_list, scm_vector_fill_x), strop.c
6326 (scm_string_split, scm_string_ci_to_symbol), strings.c
6327 (scm_string_p), sort.c (scm_merge), print.c (scm_newline),
6328 macros.c (scm_macro_type), alist.c (scm_acons, scm_assq):
6329 Docstring fixes and improvements reflecting edits that have been
6330 made in the reference manual source.
6332 * objprop.c (scm_object_properties, scm_set_object_properties_x,
6333 scm_object_property, scm_set_object_property_x): Remove invalid
6334 @deffnx lines for corresponding procedure property primitives.
6336 These changes add a @deffnx C function declaration and function
6337 index entries for each Guile primitive to the copy of the doc
6338 snarf output that is used for reference manual synchronization.
6339 Online help is unchanged.
6341 * snarf.h (SCM_SNARF_DOCS): Output primitive's C function name.
6342 (SCM_DEFINE, SCM_DEFINE1, SCM_REGISTER_PROC): Supply to C function
6343 name to SCM_SNARF_DOCS.
6345 * guile-snarf-docs-texi.in: Pass the shell script's arguments into
6346 snarf-check-and-output-texi.
6348 * Makefile.am (guile-procedures.texi): New rule.
6349 (BUILT_SOURCES, guile.texi, guile-procedures.txt, CLEANFILES):
6350 Changed so that the last stage of doc snarfing is now performed
6351 twice, once to produce guile-procedures.txt for online help, and
6352 once to produce guile.texi for reference manual synchronization.
6354 2001-11-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
6356 * eval.c (RETURN): Wrap in do{}while(0) in order to make it
6357 safely usable as a single statement followed by a ';', for example
6360 (SCM_CEVAL, SCM_APPLY): Clean up code using 'RETURN'.
6362 2001-11-13 Neil Jerram <neil@ossau.uklinux.net>
6364 * random.c (scm_random_solid_sphere_x,
6365 scm_random_hollow_sphere_x): Correct "shere" typos.
6367 * hashtab.c (scm_hash_fold): Add missing apostrophe to docstring.
6369 * version.c (scm_version): Update docstring to include
6372 2001-11-13 Marius Vollmer <mvo@zagadka.ping.de>

6377 * strop.h, strop.c (scm_substring_move_left_x,
6378 scm_substring_move_right_x): Removed.
6380 * __scm.h (HAVE_UINTPTR_T, HAVE_PTRDIFF_T, HAVE_LONG_LONG,
6381 HAVE_LONG_LONGS): Define to "1" when defining them, to mirror what
6384 2001-11-12 Marius Vollmer <mvo@zagadka.ping.de>
6386 * numbers.c: Document macros to define when including
6387 num2integral.i.c. MAX_VALUE and MIN_VALU are no longer used, we
6388 now rely on SIZEOF_ macros that have been figured out at
6391 * num2integral.i.c: Adapt to new interface.
6392 (NUM2INTEGRAL): Test whether a fixnum can be represented in the
6393 target type by casting it and checking whether it is still the
6394 same. Do not try to handle bignums for integral types that are
6395 smaller than fixnums. When handling bignums, collect the
6396 magnituse first into a unsigned type, and correctly check for
6398 (INTEGRAL2BIG): Do not use MIN_VALUE explicitely by observing that
6399 only -MIN_VALUE can still be negative of all negative numbers (in
6402 * tags.h (SIZEOF_SCM_T_BITS): Define it appropriately.
6404 * __scm.h: Define HAVE_UINTPTR_T, HAVE_PTRDIFF_T and
6405 HAVE_LONG_LONG depending on whether their size is non-zero.
6407 2001-11-11 Thien-Thi Nguyen <ttn@glug.org>
6409 * strop.c (scm_string_null_p): Docfix; nfc.
6410 Thanks to Scott Lenser.

6417 * unif.c (scm_uniform_array_write), ports.c
6418 (scm_current_output_port, scm_force_output), dynwind.c
6419 (scm_dynamic_wind), scmsigs.c (scm_setitimer, scm_getitimer),
6420 filesys.c (scm_open, scm_lstat), struct.c
6421 (scm_make_struct_layout), random.c (scm_random,
6422 scm_random_solid_sphere_x, scm_random_hollow_sphere_x, strop.c
6423 (scm_i_index): Remove superfluous whitespace from end of docstring
6426 * filesys.c (scm_select), guardians.c (scm_guardian_greedy_p),
6427 strings.c (scm_make_string), variable.c (scm_make_variable,
6428 scm_make_undefined_variable, scm_variable_p, scm_variable_set_x,
6429 scm_variable_bound_p), scmsigs.c (scm_setitimer, scm_getitimer),
6430 posix.c (scm_crypt), struct.c (scm_make_vtable_vtable), hashtab.c
6431 (scm_hash_fold), ports.c (scm_port_for_each): Remove superfluous
6432 newline at end of docstrings.
6434 * modules.c (scm_set_current_module): Add missing newline to
6437 2001-11-07 Stefan Jahn <stefan@lkcc.org>
6439 * win32-socket.[ch]: New files. Defines Winsock-API error codes
6440 and makes them available through Guile. That is because the
6441 Winsock-API does not store its errors in `errno' and thus cannot
6442 return error messages via `strerror (errno)'.
6444 * socket.c (scm_init_socket): Initialize `win32-socket' part
6445 here under M$-Windows.
6447 * numbers.h: Added missing declaration of
6448 `scm_sys_check_number_conversions()'.
6450 * error.c: Local definition of SCM_I_STRERROR and SCM_I_ERRNO
6451 and use in `(strerror)' and `(system-error)'.
6453 * Makefile.am (EXTRA_libguile_la_SOURCES): Added
6454 `win32-socket.[ch]' to extra source and header files.
6456 2001-11-06 Marius Vollmer <mvo@zagadka.ping.de>
6458 * script.c (scm_shell_usage, scm_compile_shell_switches): Prepend
6459 a call to turn-on-debugging when --debug has been given instead of
6460 turning it on directly. Also, handle new `--no-debug' option,
6461 which might suppress the call to turn-on-debugging.
6463 2001-11-05 Stefan Jahn <stefan@lkcc.org>
6465 * struct.c (s_scm_struct_vtable_p): Corrected docstring.
6467 2001-11-04 Stefan Jahn <stefan@lkcc.org>
6469 * Makefile.am (libguile_la_LIBADD): Added $(THREAD_LIBS_LOCAL)
6470 here (was at guile_LDADD) which describes the dependency
6471 correctly and allows a clean build on Win32.
6473 * __scm.h (SCM_API): Follow-up patch. Renamed __FOO__ macros
6476 * __scm.h: USE_DLL_IMPORT indicates the usage of the DLL
6477 import macros for external libraries (libcrypt, libqthreads,
6478 libreadline and libregex).
6480 * coop-defs.h: Include <winsock2.h> for `struct timeval'.
6482 * posix.c (flock): Added support for flock() in M$-Windows.
6484 * guile.c (SCM_IMPORT): Follow-up patch. Use SCM_IMPORT instead
6487 * fports.c (getflags): Differentiate reading and writing pipes
6490 * filesys.c (S_IS*): Redefine all of the S_IS*() macros for
6493 * coop.c (coop_condition_variable_timed_wait_mutex): Use
6494 conditionalized error code if `ETIMEDOUT' is not available.
6495 (scm_thread_usleep): Remove bogus declaration of `struct timeval
6498 * numbers.c (PTRDIFF_MIN): Moved this definition where it actually
6499 belongs. That is because NO_PREPRO_MAGIC gets undefined after
6500 each inclusion of `num2integral.i.c'.
6501 (SIZE_MAX): Define NO_PREPRO_MAGIC if SIZE_MAX is undefined.
6503 2001-11-03 Marius Vollmer <mvo@zagadka.ping.de>
6505 * eval.c (scm_m_begin): Allow `(begin)`, with no subforms.
6506 (SCM_CEVAL): Evaluate an empty `begin' to SCM_UNSPECIFIED.
6508 2001-11-02 Mikael Djurfeldt <mdj@linnaeus>
6510 * print.c (scm_iprin1): Mark print state as revealed when
6511 dispatching to generic write or display.
6513 * unif.c (scm_ra2contig): Fixed memory overwrite bug.
6515 2001-11-02 Marius Vollmer <mvo@zagadka.ping.de>
6517 Support for native Win32. Thanks to Stefan Jahn!
6519 * Makefile.am: Add win32-uname.c, win32-uname.h, win32-dirent.c
6520 and win32-dirent.h to extra source and header files. These
6521 include the uname() and the POSIX dirent interface implementation
6522 for M$-Windows. Put `-no-undefined' into LDFLAGS to support
6523 linkers which do not allow unresolved symbols inside shared
6524 libraries. Corrected `guile_filter_doc_snarfage$(EXEEXT)'
6527 * __scm.h: Defined SCM_API. This macro gets prepended to all
6528 function and data definitions which should be exported or imported
6529 in the resulting dynamic link library in the Win32 port.
6531 * __scm.h, alist.h, arbiters.h, async.h, backtrace.h, boolean.h,
6532 chars.h, continuations.h, coop-defs.h, coop-threads.h,
6533 debug-malloc.h, debug.h, deprecation.h, dynl.h, dynwind.h,

6544 tags.h, threads.h, throw.h, unif.h, values.h, variable.h, vectors.h,
6546 Prefixed each each exported symbol with SCM_API.
6548 * continuations.c: Added comment about the use of the extern
6549 declarations of {get,set}context() functions used in the ia64 port.
6551 * continuations.h, gc.c: `__libc_ia64_register_backing_store_base'
6552 is meant to be a `unsigned long *'.
6554 * filesys.c: Include `direct.h' if possible. Use local
6555 `win32-dirent.h' for the native M$-Windows port. Define S_IS*()
6556 macros for M$-Windows. Implementation of `fstat_Win32()' which is
6557 able to differentiate between sockets and other file descriptors.
6558 Use this function as wrapper in `scm_fstat()'. Fixed typo in
6561 * fports.c: Include `io.h' is possible. Put `*fp' into referring
6562 statement block in `scm_fport_buffer_add()'.
6563 Some corrections in `getflags()'.
6565 * gdb_interface.h (GDB_INTERFACE): Also support __CYGWIN__.
6567 * guile.c: Make sure to define __SCM_IMPORT__ for shared library
6568 build on Win32. Disable preloaded symbols on Win2 platforms.
6570 * ioext.c, ports.c: Include `io.h' is possible.
6572 * mkstemp.c: Include `process.h' is possible.
6574 * net_db.c: Disable extern declaration of `h_errno' for __CYGWIN__,
6576 Put `scm_return_entry()' into HAVE_GETSERVENT conditional.
6578 * posix.c: Remove unnecessary dirent includes and defines. Include
6579 local `win32-uname.h' for MinGW. Extern declaration of
6580 `mkstemp()' for systems where it does not exists. Make
6581 `getlogin()' available on M$-Windows.
6583 * scmsigs.c: Made `usleep()' avalable on MinGW.
6585 * stime.c: On M$-Windows `tzname[]' is known to be `_tzname[]'.
6587 * win32-dirent.c: Include "win32-dirent.h", not "dirent.h".
6589 * win32-uname.c: Include "win32-uname.h", not "uname.h".
6591 2001-10-28 Mikael Djurfeldt <mdj@linnaeus>
6593 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write):
6594 Don't apply scm_uniform_vector_length on arrays.
6596 2001-10-14 Dirk Herrmann <D.Herrmann@tu-bs.de>
6598 * eval.c (scm_lookupcar, scm_m_letstar, scm_m_do, iqq,
6599 scm_m_define, scm_m_letrec1, scm_m_let, scm_m_expand_body,
6600 scm_macroexp, unmemocopy, scm_eval_args, scm_deval_args,
6601 SCM_CEVAL, scm_map, scm_init_eval): When building lists, prefer
6602 scm_list_<n> over scm_cons[2]?.
6604 (scm_unmemocar, scm_m_cond, scm_m_letstar, scm_m_letrec1,
6605 scm_m_let, scm_m_atbind, unmemocopy, SCM_CEVAL, SCM_APPLY): Use
6606 SCM_C[AD][AD]R instead of explicit form.
6608 (scm_m_set_x, scm_m_cond, scm_m_letstar, scm_m_do): Reordered
6609 comparison parameters.
6611 (scm_m_case, scm_m_cond, scm_m_letstar, scm_m_do, SCM_CEVAL): Use
6612 !SCM_NULLP instead of SCM_NIMP.
6614 (scm_m_case): Don't copy the form. Renamed proc to clause and
6615 minimized its scope. Renamed x to clauses. Removed side
6616 effecting operation from macro call.
6618 (scm_m_cond): Don't copy the form. Renamed arg1 to clause and
6619 minimized its scope. Renamed x to clauses. Minimized the scope
6620 of variable 'len'. Make sure the else clause is treated specially
6621 even in case of '=>' occurences. Don't change the else to #t in
6622 order to be able to distinguish this case in the evaluator. Leave
6623 type checking of the recipient to the evaluator.
6625 (scm_c_improper_memq): Made the comment somewhat clearer.
6627 (scm_m_lambda): Renamed proc to formals. Removed unnecessary
6628 test for SCM_IM_LET at the place of the formal parameters.
6629 Simplified the formal parameter checking.
6631 (scm_m_letstar): Added Comment. Renamed proc to bindings.
6632 Renamed arg1 to binding and minimized its scope. Eliminated
6633 unnecessary consing.
6635 (scm_m_do): Renamed proc to bindings. Minimized the scope of
6638 (build_binding_list): New static function.
6640 (unmemocopy): Don't use SCM_TYP7 on pairs (it's unclean).
6641 Further, split up the 'letrec' unmemoizing code to the
6642 corresponding parts for 'do', 'let' and 'letrec', adding comments
6643 to each form. Cleanup the handling of the do form (This removes
6644 some *real* code :-).
6646 (SCM_CEVAL): Removed side effecting operation from macro call.
6647 Handle the 'else clause of the 'cond form specially - the symbol
6648 'else is not replaced with #t any more.
6650 2001-10-14 Gary Houston <ghouston@arglist.com>
6652 * version.c (scm_version): use sprintf instead of snprintf,
6653 for portability. thanks to Bill Schottstaedt.
6655 2001-10-14 Mikael Djurfeldt <mdj@linnaeus>
6657 * read.c (scm_lreadr): When user-defined hash procedure returns
6658 SCM_UNSPECIFIED: Fall back to standard handling instead of raising
6659 an exception. (This prevents parsing of uniform vectors from
6660 interfering with parsing of numbers.)
6662 2001-10-13 Marius Vollmer <mvo@zagadka.ping.de>
6664 * numbers.c: Set NO_PREPRO_MAGIC when defining our version of
6665 PTRDIFF_MIN. Thanks to Ken Raeburn.
6667 2001-10-07 Marius Vollmer <mvo@zagadka.ping.de>
6669 * Makefile.am (EXTRA_libguile_la_SOURCES): Added "mkstemp.c".
6671 * eval.c (scm_m_atbind): First try to find the variable without
6672 defining it locally; when it has not been found, define it
6675 * modules.c (module_variable): Pass over variables that exist but
6678 2001-10-06 Marius Vollmer <mvo@zagadka.ping.de>
6680 * backtrace.c (display_backtrace_file_and_line): Only use
6681 scm_basename when POSIX support is compiled in. Thanks to Chris
6684 2001-10-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
6686 * numbers.c (mem2uinteger): Return number read so far when coming
6687 across a hexdigit after having read a # or if not reading a hex
6688 value. This will enable the calling code to correctly handle
6689 forms like 1e2. (The background is, that the exponent markers d,
6690 e and f are also hexdigits.) Thanks to Mikael Djurfeldt for
6691 providing this patch.
6693 (mem2complex): Fix erroneous double-negation. Now, numbers like
6694 1-i will be read correctly.
6696 2001-10-12 Mikael Djurfeldt <mdj@linnaeus>
6698 * debug.c (scm_mem_to_proc): Fixed typo in previous change.
6700 * validate.h (SCM_VALIDATE_DOUBLE_DEF_COPY): New macro.
6702 2001-10-12 Dirk Herrmann <D.Herrmann@tu-bs.de>
6704 * print.c (scm_print_state_vtable, print_state_pool):
6705 Initialize. These variables are now registered as gc roots.
6707 (scm_current_pstate): Update documentation.
6709 (scm_current_pstate, scm_make_print_state, scm_free_print_state,
6710 scm_prin1, scm_init_print): print_state_pool is registered as a
6711 gc root and thus does not need to be protected by a surrounding
6714 (make_print_state): The car of print_state_pool no longer holds
6715 the scm_print_state_vtable.
6717 (scm_current_pstate, scm_make_print_state, print_circref,
6718 scm_iprin1, scm_prin1, scm_iprlist): Prefer !SCM_<foo> over
6721 (scm_prin1): When building lists, prefer scm_list_<n> over
6724 (scm_iprlist): Removed a redundant SCM_IMP test.
6726 (scm_simple_format): Use SCM_EQ_P to compare SCM values.
6728 2001-10-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
6730 * debug.c (scm_make_iloc): Prefer !SCM_<foo> over SCM_N<foo>.
6732 (scm_memcons, scm_mem_to_proc): When building lists, prefer
6733 scm_list_<n> over scm_cons[2]?.
6735 (scm_mem_to_proc): Prefer SCM_CONSP over SCM_NIMP.
6737 (scm_procedure_name): Use SCM_CADR instead of explicit form.
6739 (debugobj_print): Coerce scm_intprint arg 1 to long, not int.
6740 Thanks to Rob Browning for the patch (see log entry 2001-09-21) -
6741 for some reason his patch didn't make it into the cvs.
6743 2001-10-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
6745 * numbers.c (mem2decimal_from_point): Cleaned up the parsing a
6746 little bit - should even be somewhat more accurate now.
6748 2001-10-08 Rob Browning <rlb@defaultvalue.org>
6750 * gc.c: support ia64 register backing store.
6751 (SCM_MARK_BACKING_STORE): new macro.
6753 * continuations.h: support ia64 register backing store.
6754 (struct scm_t_contregs): add ia64 register backing store.
6756 * continuations.c: support ia64 register backing store.
6757 (continuation_mark): mark ia64 register backing store.
6758 (continuation_free): free ia64 register backing store.
6759 (scm_make_continuation): capture ia64 register backing store.
6760 (copy_stack_and_call): copy ia64 register backing store.
6762 2001-10-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
6764 * hashtab.c (scm_hash_fn_create_handle_x): The result of assoc_fn
6765 is known to be #f if no entry is found. Thus, use !SCM_FALSEP
6766 instead of SCM_NIMP to test for that case.
6768 * strings.h (SCM_SET_STRING_LENGTH): Cast the length to
6769 scm_t_bits instead of long.
6771 2001-10-06 Marius Vollmer <mvo@zagadka.ping.de>
6773 * tags.h (SCM_T_BITS_MAX, SCM_T_SIGNED_BITS_MAX,
6774 SCM_T_SIGNED_BITS_MIN): New.
6775 * numbers.h (SCM_MOST_POSITIVE_FIXNUM, SCM_MOST_NEGATIVE_FIXNUM):
6776 Use them to make these macros computable by the preprocessor.
6778 * num2integral.i.c (INTEGRAL2NUM): Let the preprocessor test
6779 whether the integral type fits in a fixnum, not the compiler.
6780 This removes a spurious compiler warning. Also, honor the
6781 NO_PREPRO_MAGIC flag to suppress any preprocessor tests. This is
6782 needed for `long long's.
6784 * numbers.c: Define NO_PREPRO_MAGOC when including
6785 num2integral.c.i for `long long' and `signed long long'.
6787 2001-10-06 Mikael Djurfeldt <mdj@linnaeus>
6789 These changes fixes a race condition in the Guile coop - pthread
6792 * coop.c (mother_awake_p): New variable.
6793 (coop_create): Set mother_awake_p before creating or signalling
6794 mother; wait until mother is going to sleep before returning.
6795 (mother): Reset mother_awake_p before going to sleep.
6797 2001-10-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
6799 * options.c (protected_objects, scm_init_options): The content of
6800 protected_objects is now protected from garbage collection using
6801 scm_gc_register_root instead of scm_permanent_object.
6803 (get_option_setting): New static function that computes an option
6804 setting as it was formerly done in the function scm_options.
6806 (get_documented_option_setting): New static function that
6807 returns option documentation as it was formerly done in the
6808 function scm_options. Note that documentation C strings are no
6809 longer precomputed into SCM objects. Instead, they are converted
6810 into SCM strings every time get_documented_option_setting is
6813 (change_option_setting): New static functions that modifies the
6814 option setting as it was formerly done in the function
6815 scm_options. The function is now exception safe, i. e. won't
6816 cause a memory leak when interrupted. Further, only non-immediate
6817 option values are added to the protection list.
6819 (scm_options): This function now has only the purpose to dispatch
6820 to to get_option_setting, get_documented_option_setting or
6821 change_option_setting, depending on the arguments given to
6824 (scm_init_opts): Don't convert documentation C strings into SCM
6825 strings. Further, don't protect any object values: They _must_
6826 be immediate values, otherwise there is no guarantee that they
6827 have not been collected before anyway.
6829 * options.[ch] (scm_t_option): Made type unsigned, name into a
6830 constant char* and val into a scm_t_bits type.
6832 (scm_options, scm_init_opts): The number of options is guaranteed
6833 to be larger or equal to zero. Thus, the type is changed to
6836 2001-10-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
6838 * num2integral.i.c (NUM2INTEGRAL): Eliminated some warnings about
6839 testing an unsigned value for being >= 0.
6841 2001-10-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
6843 * numbers.h: Removed old comment about using SCM_CAR to access
6846 (SCM_MOST_POSITIVE_FIXNUM, SCM_MOST_NEGATIVE_FIXNUM): Make sure
6847 the return value is signed. Thanks to Brian Crowder for the bug
6850 (SCM_SRS): Avoid unnecessary casting and don't unpack input
6851 values. With this patch, SCM_SRS can be safely used for other
6852 types than scm_t_signed_bits. However, it should still better be
6853 an internal macro and thus be renamed to SCM_I_SRS.
6855 (SCM_MAKINUM, SCM_INUM): Use proper casting.
6857 2001-10-03 Gary Houston <ghouston@arglist.com>
6859 * continuations.h, unif.h: in the descriptions of the bit patterns
6860 of the heap cells, make bit 0 the least significant.
6862 2001-09-25 Thien-Thi Nguyen <ttn@glug.org>
6864 * chars.h (SCM_MAKE_CHAR): Use `scm_t_bits' instead of `intptr_t'.
6865 Thanks to Golubev I. N.
6867 2001-09-25 Gary Houston <ghouston@arglist.com>
6869 * ports.c (scm_drain_input): extended the docstring. thanks to
6870 Alex Schroeder and Thien-Thi Nguyen.
6872 2001-09-23 Mikael Djurfeldt <mdj@linnaeus>
6874 * validate.h (SCM_NUM2FLOAT, SCM_NUM2DOUBLE,
6875 SCM_VALIDATE_FLOAT_COPY, SCM_VALIDATE_DOUBLE_COPY): New
6876 macros. (The NUM names might soon change.)
6878 * numbers.h: Added missing declarations.
6880 2001-09-22 Mikael Djurfeldt <mdj@linnaeus>
6882 * Makefile.am: Distribute num2float.i.c.
6884 * num2float.i.c: New file, multiply included by numbers.c, used
6885 to "templatize" the float <-> num conversion routines.
6887 * numbers.c: New functions: scm_num2float, scm_float2num,
6888 scm_num2double, scm_double2num.
6890 2001-09-21 Rob Browning <rlb@defaultvalue.org>
6892 * .cvsignore: really add version.h
6894 * strings.h (SCM_SET_STRING_LENGTH): coerce "l" to a long.
6895 Otherwise it fails on the alpha. However, we might rather choose
6896 this size conditionally.
6898 * numbers.c (scm_gcd): change "k" to a long from an int.
6899 Otherwise it fails on the alpha. However, we might rather choose
6900 this size conditionally.
6902 * error.c (scm_wta): coerce char* to intptr_t before int
6905 * debug.c (debugobj_print): coerce scm_intprint arg 1 to long, not
6908 * chars.h (SCM_MAKE_CHAR): coerce value to intptr_t.
6910 2001-09-20 Mikael Djurfeldt <mdj@linnaeus>
6912 * numbers.c (scm_integer_expt): Accept inexact integer in second
6913 argument. (Thanks to Bill Schottstaedt.)
6915 2001-09-20 Rob Browning <rlb@defaultvalue.org>
6917 * .cvsignore: add version.h
6919 * versiondat.h.in: removed (obsolete).
6921 * version.h.in: renamed from version.h.
6922 (SCM_GUILE_MAJOR_VERSION): new public macro.
6923 (SCM_GUILE_MINOR_VERSION): new public macro.
6924 (SCM_GUILE_MICRO_VERSION): new public macro.
6926 * version.h: renamed to version.h.in.
6929 (scm_major_version): support integer *_VERSION macros.
6930 (scm_minor_version): support integer *_VERSION macros.
6931 (scm_micro_version): support integer *_VERSION macros.
6932 (scm_version): support integer *_VERSION macros.
6934 2001-09-20 Mikael Djurfeldt <mdj@linnaeus>
6936 * error.c, error.h: Made error keys globally accessible.
6937 Applications might want to test for these or use them in a direct
6940 * num2integral.i.c (NUM2INTEGRAL): Report an error when these
6941 routines are passed an inexact. This change in behavior is
6942 motivated by concordance with R5RS: It is more common that a
6943 primitive doesn't want to accept an inexact for an exact.
6945 2001-09-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
6947 The following patch partially undoes my patch from 2001-06-30,
6948 where I added the function scm_gc_mark_cell_conservatively. The
6949 function is buggy, since it breaks guile during conservative
6950 marking if a pointer on the stack points directly into the list of
6951 free cells on the heap: With conservative cell marking this will
6952 cause the whole free list to be scanned and marked - boom!
6954 * gc.c (allocated_mark, MARK, heap_segment,
6955 scm_gc_mark_cell_conservatively, scm_init_storage), gc.h
6956 (scm_gc_mark_cell_conservatively): Remove function
6957 scm_gc_mark_cell_conservatively and update the corresponding
6958 comments and uses accordingly. Thanks to Christopher Cramer for
6959 the patch. (Minor corrections by me.)
6961 2001-09-15 Gary Houston <ghouston@arglist.com>
6963 * root.h (scm_root_state): removed the continuation_stack and
6964 continuation_stack_ptr members, which have no apparent purpose.
6965 (scm_continuation_stack, scm_continuation_stack_ptr): #defines
6968 * root.c (root_mark), init.c (restart_stack, start_stack), gc
6969 (scm_igc): remove all references to contination_stack and
6970 continuation_stack_ptr, avoiding allocation of a vector and
6971 useless processing during gc.
6973 2001-09-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
6975 * guardians.c (tconc_t, t_tconc): Renamed tconc_t to t_tconc.
6977 (TCONC_IN): Make sure that the cell word 0 is initialized last.
6979 (guardians_t, t_guardians): Renamed guardians_t to t_guardians.
6981 (GUARDIAN, GUARDIAN_DATA): Renamed GUARDIAN to GUARDIAN_DATA.
6983 (guardian_apply, scm_get_one_zombie, scm_make_guardian,
6984 mark_and_zombify): Prefer !SCM_<foo> over SCM_N<foo>.
6986 2001-09-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
6988 * guardians.c (mark_dependencies_in_tconc,
6989 whine_about_self_centered_zombies, scm_init_guardians): Register
6990 the static global variable `self_centered_zombies' via
6991 scm_gc_register_root, to make some cdr-ing unnecessary.
6993 2001-09-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
6995 * backtrace.c (display_backtrace_file,
6996 display_backtrace_file_and_line): Use SCM_EQ_P when comparing SCM
6997 values, use SCM_FALSEP when comparing SCM values against #f.
6998 Thanks to Rob Browning for the bug report.
7000 2001-09-12 Martin Baulig <martin@home-of-linux.org>
7002 * strings.[ch] (scm_str2string): New function.
7004 2001-09-06 Marius Vollmer <mvo@zagadka.ping.de>
7006 * gc.c (scm_done_free): Always subtract size from scm_mallocated
7007 when computing nm, even if it's negative.
7008 (scm_must_malloc): Abort on overflow of scm_mtrigger.
7009 (scm_must_realloc): Likewise.
7011 2001-09-01 Michael Livshin <mlivshin@bigfoot.com>
7013 * numbers.c (scm_sys_check_number_conversions): new function,
7014 defined if Guile is compiled in debugging mode. currently checks
7015 `scm_num2ulong', should check much much more.
7017 * num2integral.i.c (NUM2INTEGRAL): when converting a bignum to
7018 unsigned, ensure that it's positive. thanks to Martin Baulig!
7020 2001-08-31 Dirk Herrmann <D.Herrmann@tu-bs.de>
7022 * __scm.h: Added new section about compile time selectable
7025 (long_long, ulong_long, scm_sizet, SCM_WNA, SCM_OUTOFRANGE,
7026 SCM_NALLOC, SCM_HUP_SIGNAL, SCM_INT_SIGNAL, SCM_FPE_SIGNAL,
7027 SCM_BUS_SIGNAL, SCM_SEGV_SIGNAL, SCM_ALRM_SIGNAL, SCM_GC_SIGNAL,
7028 SCM_TICK_SIGNAL, SCM_SIG_ORD, SCM_ORD_SIG, SCM_NUM_SIGS):
7031 * deprecation.c (scm_include_deprecated_features): Simplified.
7033 * eval.c (EVALCAR, unmemocopy), eval.h (SCM_XEVALCAR): Use
7034 `SCM_IMP´ instead of `!SCM_CELLP´.
7036 * eval.c (unmemocopy): Eliminate redundant SCM_CELLP tests.
7037 Extract side-effecting operations from macros.
7039 (scm_init_eval): Don't initialize *top-level-lookup-closure*,
7040 scm_top_level_lookup_closure_var and scm_system_transformer.
7042 * gc.c (CELL_P): New local definition to replace SCM_CELLP.
7044 (heap_segment): Use CELL_P instead of SCM_CELLP.
7046 * init.c (start_stack): Don't initialize
7047 scm_top_level_lookup_closure_var and scm_system_transformer.
7049 * modules.c (scm_set_current_module): Don't access
7050 scm_top_level_lookup_closure_var and scm_system_transformer.
7052 (scm_sym2var): Don't call scm_variable_set_name_hint.
7054 (scm_post_boot_init_modules): Removed deprecated initializations.
7056 * print.c (scm_ipruk): Don't access cell contents of non cells.
7058 * strings.c (scm_string_set_x): All strings are writable.
7060 * strings.h (SCM_STRINGP): Use SCM_TYP7 to determine the string
7061 type. There is only one string type now.
7063 (SCM_STRING_COERCE_0TERMINATION_X): Deprecated.
7065 * tags.h: Remove comments about two different string types.
7067 (SCM_CELLP, SCM_NCELLP): Deprecated.
7069 * variable.c (make_variable): Remove code variant for vcells.
7071 * variable.h (SCM_VARIABLE_REF, SCM_VARIABLE_SET,
7072 SCM_VARIABLE_LOC): Remove code variant for vcells.
7074 * __scm.h, deprecation.[ch]: Renamed SCM_DEBUG_DEPRECATED to
7075 SCM_ENABLE_DEPRECATED with the logic reversed.
7077 * dynl.c (moddata, registered_mods), dynl.[ch]
7078 (scm_register_module_xxx, scm_registered_modules,
7079 scm_clear_registered_modules), error.[ch] (scm_wta), eval.c
7080 (*top-level-lookup-closure*), eval.[ch]
7081 (scm_top_level_lookup_closure_var, scm_system_transformer,
7082 scm_eval_3, scm_eval2), gc.h (SCM_SETAND_CAR, SCM_SETOR_CAR,

7536 hold predefined symbols.
7538 (build_class_class_slots): Build the list using scm_list_n
7539 instead of cons. Also, slots are already created as lists, thus
7540 making a call to maplist unnecessary.

7622 * .cvsignore: add stamp-h.in.
7624 2001-07-04 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
7626 * hooks.c (scm_make_hook, scm_add_hook_x),

7643 2001-07-01 Marius Vollmer <mvo@zagadka.ping.de>
7645 * strports.c (scm_read_0str, scm_eval_0str): Call
7646 scm_c_read_string and scm_c_eval_string respectively, not
7647 themselves. Thanks to Dale P. Smith!
7649 2001-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
7651 * unif.c (scm_array_set_x): The variable args does not
7652 necessarily have to be a list. Further, got rid of a redundant
7655 2001-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
7657 * list.c (SCM_I_CONS): Make sure the cell type is initialized
7660 * gc.c (s_scm_map_free_list, scm_igc, scm_gc_sweep,
7661 init_heap_seg): Fixed signedness.
7663 (init_heap_seg): Replaced strange for-loop with a while loop.
7665 * weaks.h (WEAKSH, SCM_WEAKS_H): Rename <foo>H to SCM_<foo>_H.
7667 (SCM_WVECTP): Prefer !SCM_<pred> over SCM_N<pred>.
7669 The following patch adds conservative marking for the elements of
7670 free or allocated cells.
7672 * gc.c (allocated_mark, heap_segment): New static functions.
7674 (which_seg): Deleted, since the functionality is now provided by
7675 function heap_segment.
7677 (map_free_list): Use heap_segment instead of which_seg.
7679 (MARK): If cell debugging is disabled, mark free cells
7682 (scm_mark_locations, scm_cellp): Extracted the search for the
7683 heap segment of a SCM value into function heap_segment.
7685 (scm_init_storage): Allocated cells must be marked
7688 * gc.[ch] (scm_gc_mark_cell_conservatively): New function.
7690 The following patch changes the representation of weak vectors to
7691 double cells instead of using an extension of the vector's
7694 * gc.c (MARK): Use SCM_SET_WVECT_GC_CHAIN instead of assigning to
7695 the result of SCM_WVECT_GC_CHAIN.
7697 (scm_gc_sweep): Weak vectors don't have extra fields any more.
7699 * weaks.c (allocate_weak_vector): New static function. It does
7700 not patch any previously created vector object during the
7701 construction of a weak vector, and thus doesn't need to switch
7702 off interrupts during vector creation.
7704 (scm_make_weak_vector, scm_make_weak_key_hash_table,
7705 scm_make_weak_value_hash_table, scm_make_doubly_weak_hash_table):
7706 Use allocate_weak_vector to provide the new weak vector object.
7708 * weaks.h (SCM_WVECT_TYPE, SCM_SET_WVECT_TYPE,
7709 SCM_SET_WVECT_GC_CHAIN): New macros. The weak vector subtype is
7710 now stored in the double cell.
7712 (SCM_IS_WHVEC, SCM_IS_WHVEC_V, SCM_IS_WHVEC_B, SCM_IS_WHVEC_ANY):
7715 (SCM_WVECT_GC_CHAIN): The weak objects are now chained together
7716 using an entry of the double cell.
7718 2001-06-30 Thien-Thi Nguyen <ttn@revel.glug.org>
7720 * stamp-h.in: bye bye
7722 2001-06-30 Marius Vollmer <mvo@zagadka.ping.de>
7724 * gh_eval.c (gh_eval_str): Use scm_c_eval_string instead of
7727 * load.c, load.h (scm_c_primitive_load,
7728 scm_c_primitive_load_path): New.
7730 * strports.c, strports.h (scm_c_read_string): Renamed from

7745 SCM_LIST6, SCM_LIST7, SCM_LIST8, SCM_LIST9, scm_listify): Deprecated.
7746 (lots of files): Use the new functions.
7748 * goops.c (CALL_GF1, CALL_GF2, CALL_GF3, CALL_GF4): Use scm_call_N.
7750 * strings.c: #include "libguile/deprecation.h".
7752 2001-06-27 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
7754 * read.c (scm_lreadr): When reading a hash token, check for a
7755 user-defined hash procedure first, so that overriding the builtin
7756 hash characters is possible (this was needed for implementing
7757 SRFI-4's read synax `f32(...)').
7759 * num2integral.i.c: Use scm_t_signed_bits instead of scm_t_bits,
7760 because the latter is unsigned now and breaks comparisons like
7761 (n < (scm_t_signed_bits)MIN_VALUE).
7763 2001-06-26 Neil Jerram <neil@ossau.uklinux.net>
7765 * eval.h, eval.c (scm_call_4): New function.
7767 * eval.c (SCM_APPLY, SCM_CEVAL, ENTER_APPLY): Call trap handlers
7768 directly rather than dispatching to them via scm_ithrow and a lazy
7771 * eval.c (scm_evaluator_trap_table), eval.h (SCM_ENTER_FRAME_HDLR,
7772 SCM_APPLY_FRAME_HDLR, SCM_EXIT_FRAME_HDLR): Add three new options
7773 for trap handler procedures.
7775 * debug.h (SCM_RESET_DEBUG_MODE): Add checks for trap handler
7776 procedures not being #f.
7778 2001-06-27 Michael Livshin <mlivshin@bigfoot.com>
7780 * Makefile.am (c-tokenize.c): add rule to generate it.
7781 (EXTRA_DIST): add c-tokenize.lex, so it gets distributed.
7783 filter-doc-snarfage.c: remove.
7785 2001-06-26 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
7787 * ports.c (scm_output_port_p): Use result of SCM_COERCE_OUTPORT.
7789 The following set of changes makes compiling Guile under various
7790 Windows compilers easier. Compilation under GNU systems should
7791 not be affected at all.
7793 Thanks to Stefan Jahn for all necessary information, patches and
7796 * posix.c: Conditialize getpwent, getgrent, kill, getppid, getuid,

7804 Windows and conditionalize some signal names.
7806 * socket.c (scm_getsockopt): Added missing comma.
7807 Include socket library header under Windows.

7814 * net_db.c: Do not declare errno under Windows.
7816 * iselect.h, inet_aton.c: Include socket library headers under
7819 * guile.c (inner_main): Under Windows, initialize socket library
7820 and initialize gdb_interface data structures.
7822 * gdb_interface.h: Under Windows, gdb_interface cannot be
7823 initialized statically. Initialize at runtime instead.
7825 * fports.c (write_all): ssize_t -> size_t.
7826 (fport_print): Conditionalize call to ttyname().
7827 (getflags): New function, compiled only under Windows.
7829 * filesys.c: Conditionalize inclusion of <pwd.h>. Conditionalize
7830 primitives chown, link, fcntl.
7831 (scm_basename, scm_dirname): Under Windows, handle \ as well as /
7834 * backtrace.c: Include <io.h> under Windows.

7872 * filesys.c (scm_close), ports.c (scm_close_port,
7873 scm_port_closed_p), strop.c (scm_string_null_p): Use SCM_BOOL
7874 instead of SCM_NEGATE_BOOL.

7910 * strings.h (STRINGSH, SCM_STRINGS_H): Rename <foo>H to
7913 * validate.h (SCM_VALIDATE_SUBSTRING_SPEC_COPY): Eliminate
7914 warning about comparing signed and unsigned values. This fix is
7915 not optimal, since it won't work reliably if sizeof (c_start) >
7916 sizeof (size_t) or sizeof (c_end) > sizeof (size_t). A better
7917 solution is to define this macro as an inline function, thus
7918 allowing to specifiy the types of c_start and c_end.
7920 2001-06-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
7922 * debug.h (SCM_DEBUGOBJ_FRAME): Deliver result as a

7944 (scm_last_stack_frame): Remove bogus `;´.
7946 * stacks.h (SCM_FRAMEP): Fix type check.
7948 2001-06-25 Michael Livshin <mlivshin@bigfoot.com>
7950 * Makefile.am (MAINTAINERCLEANFILES): be sure to remove
7951 c-tokenize.c when doing maintainer-clean.
7953 * snarf.h (SCM_SNARF_DOCS): change the "grammar" slightly.
7955 * guile-snarf-docs.in, guile-snarf-docs-texi.in: rewrite &
7958 * eval.c: all hash signs are in column 0.
7960 * Makefile.am (guile_filter_doc_snarfage): build using
7961 c-tokenize.c, not filter-doc-snarfage.c.
7962 rearrange snarfing dependencies a bit.

8407 Thanks to Han-Wen Nienhuys for the suggestion.
8409 * unif.c (scm_array_set_x): Fix typing problem, and use

8458 Changed use of scm_array->scm_array_t and
8459 scm_array_dim->scm_array_dim_t to enable build with
8460 --disable-deprecated.
8462 2001-05-24 Michael Livshin <mlivshin@bigfoot.com>
8464 The purpose of this set of changes is to regularize Guile's usage
8465 of ANSI C integral types, with the following ideas in mind:
8467 - SCM does not nesessarily have to be long.
8468 - long is not nesessarily enough to store pointers.
8469 - long is not nesessarily the same size as int.
8471 The changes are incomplete and possibly buggy. Please test on
8475 (SCM_NUM2{SIZE,PTRDIFF,SHORT,USHORT,BITS,UBITS,INT,UINT}[_DEF]):
8478 * unif.h: type renaming:
8479 scm_array -> scm_array_t
8480 scm_array_dim -> scm_array_dim_t
8481 the old names are deprecated, all in-Guile uses changed.
8483 * tags.h (scm_ubits_t): new typedef, representing unsigned
8486 * stacks.h: type renaming:
8487 scm_info_frame -> scm_info_frame_t
8488 scm_stack -> scm_stack_t
8489 the old names are deprecated, all in-Guile uses changed.
8491 * srcprop.h: type renaming:
8492 scm_srcprops -> scm_srcprops_t

9486 * init.c, goops.c, goops.h: Reverted change of 2001-03-29. (The
9487 goops module should be registered in order to work for an
9488 application which uses libguile statically linked.)

9637 2001-03-31 Michael Livshin <mlivshin@bigfoot.com>
9639 * backtrace.c (display_backtrace_body): since the `print_state'
9640 variable is not used (instead its data field is used directly as
9641 `pstate'), protect it from the hungry compiler optimizations.
9642 thanks to Bill Schottstaedt for the report.
9644 2001-03-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
9646 * gc.[ch] (scm_tc16_allocated): New type tag for allocated cells.
9647 It is only defined and used if guile is compiled with
9648 SCM_DEBUG_CELL_ACCESSES set to true. It's purpose is, to never
9649 let cells with a free_cell type tag be visible outside of the
9650 garbage collector when in debug mode.
9652 * gc.c (scm_debug_cell_accesses_p): Set to true as default.
9654 (scm_assert_cell_valid): Use a local static variable to avoid
9657 (MARK): Only check for rogue cell pointers in debug mode. Use
9658 scm_cellp for this purpose and place all checks for rogue pointers
9659 into that function. Further, since due to conservative scanning
9660 we may encounter free cells during marking, don't use the standard
9661 cell type accessor macro to determine the cell type.
9663 (scm_cellp): Check if the cell pointer actually points into a
9666 (scm_init_gc): Initalize scm_tc16_allocated.
9668 * gc.h (GCH): Renamed to SCM_GC_H.
9670 (SCM_VALIDATE_CELL): Enclose the expression in brackets. This
9671 might be unnecessary, but I feel better this way :-)
9673 (SCM_GC_CELL_TYPE): New macro.
9675 (SCM_SETAND_CDR, SCM_SETOR_CDR): Deprecated. These are not used
9676 in guile, and it is unlikely that they will be applied to real
9679 (SCM_SET_FREE_CELL_TYPE): Removed. It was not used.
9681 (SCM_GC_SET_ALLOCATED): New macro. Only non-empty if guile is
9682 compiled with SCM_DEBUG_CELL_ACCESSES set to true.
9684 (SCM_NEWCELL, SCM_NEWCELL2): Use of SCM_GC_SET_ALLOCATED will
9685 make sure that in debug mode no free cell will ever be visible
9686 outside of the garbage collector.
9688 2001-03-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
9690 * async.c (scm_asyncs_pending): Don't use != to compare SCM

9697 Remove suspicious use of SCM_SLOPPY_CONSP.
9699 * eq.c (scm_equal_p), tags.h (SCM_ECONSP): Use SCM_CONSP instead
9700 of SCM_SLOPPY_CONSP. A sane compiler should be able to perform
9701 the corresponding optimization.
9703 * eval.c (iqq): Use proper type check.
9705 (scm_m_expand_body): Remove redundant type checks.
9707 (promise_print): Don't access promise cells as pairs.
9709 * eval.c (EVALCAR, iqq, scm_m_expand_body, scm_eval_args,
9710 scm_deval_args SCM_CEVAL), guardians.c (scm_guard), hashtab.c
9711 (scm_internal_hash_fold), print.c (scm_iprlist): Use !SCM_CELLP
9712 for SCM_NCELLP, !SCM_CONSP for SCM_NCONSP, !SCM_IMP for SCM_NIMP,
9713 !SCM_FALSEP for SCM_NFALSEP, !SCM_NULLP for SCM_NNULLP
9715 * eval.c (scm_m_define, scm_macroexp, SCM_CEVAL), print.c
9716 (scm_iprin1): Use new macro predicate and accessors.
9718 * eval.h (scm_tc16_macro): Removed declaration. It is declared
9721 * eval.h (EVALH), macros.h (MACROSH), ports.h (PORTSH), procs.h
9722 (PROCSH), tags.h (TAGSH), variable.h (VARIABLEH): Renamed to
9723 SCM_EVAL_H, SCM_MACROS_H, SCM_PORTS_H, SCM_PROCS_H, SCM_TAGS_H and
9724 SCM_VARIABLE_H. Even the macros that are used to inhibit
9725 including a header file twice should be in the SCM_ namespace.
9727 * fluids.c (scm_swap_fluids, scm_swap_fluids_reverse),
9728 properties.c (scm_primitive_property_ref,
9729 scm_primitive_property_del_x): Prefer stronger predicates like
9730 SCM_NULLP or SCM_FALSEP over SCM_IMP.
9732 * gc.c (MARK): Use proper macros to access procedure-with-setter
9733 cell elements and closure cell elements.
9735 (gc_sweep_freelist_finish, scm_gc_sweep, init_heap_seg): Don't
9736 access free cells as pairs.
9738 (scm_unprotect_object): scm_hashq_get_handle returns #f if
9739 no hashtab entry is found.
9741 * gc.c (scm_gc_sweep), ports.c (scm_close_port): Use new macro
9742 SCM_CLR_PORT_OPEN_FLAG.
9744 * guardians.c (TCONC_IN), print.c (scm_free_print_state): Don't
9745 use SCM_SET_C[AD]R for uninitialized cells.
9747 * hashtab.c (scm_hash_fn_get_handle): Use SCM_VALIDATE_VECTOR.
9748 If the hashtable has no slots, return #f instead of '(). This
9749 unifies the return value with most assoc-functions.
9751 (scm_hash_fn_ref): Use proper type check.
9753 (scm_hashq_get_handle, scm_hashv_get_handle, scm_hash_get_handle):
9754 Removed references to non-existing functions from documentation.
9756 * keywords.c (scm_keyword_dash_symbol): Use proper macros to
9757 access keyword cell elements.
9759 * macros.h (SCM_MACROP, SCM_MACRO_TYPE, SCM_MACRO_CODE): New
9762 * ports.h (SCM_CLR_PORT_OPEN_FLAG): New macro.

9770 * smob.c (scm_markcdr): Don't access smob cells as pairs.
9772 * tags.h (SCM_SLOPPY_CONSP, SCM_SLOPPY_NCONSP): Deprecated.

9777 * variable.c (variable_print, variable_equalp, scm_variable_ref,
9778 scm_variable_set_x): Use proper macros to access variable cell
9781 (scm_variable_bound_p): Don't use SCM_NEGATE_BOOL.
9783 * variable.h (SCM_VARVCELL): Don't access variable cells as
9786 * vectors.c (scm_vector), weaks.c (scm_weak_vector): Simplified,
9787 added FIXME comment, removed register specifier.
9789 2001-03-29 Keisuke Nishida <kxn30@po.cwru.edu>
9791 * goops.c, goops.h (scm_init_oop_goops_goopscore_module): Deprecated.
9792 * init.c (scm_init_guile_1): Don't init goopscore module.
9794 2001-03-27 Marius Vollmer <mvo@zagadka.ping.de>
9796 * eval.c (SCM_APPLY): Check that arg1 is bound for scm_tc7_cxr.

9821 New delcarations to support above change.
9823 * eval.c (scm_primitive_eval_x, scm_primitive_eval): Fix syntax
9824 errors with last change.
9826 2001-03-25 Marius Vollmer <mvo@zagadka.ping.de>

9829 scm_i_eval): Moved the application of the system transformer from
9830 scm_i_eval to scm_primitive_eval.

10032 * macros.h (SCM_ASSYNT): On assertion failure, issue a misc-error

10058 * error.c, net_db.c, putenv.c, stime.c: Removed declaration of
10059 errno variable (can be a macro on some systems, for example when

10112 * posix.c: Added inclusion of <crypt.h>, <sys/resource.h> and
10113 <sys/file.h>, if present.
10114 (scm_init_posix): [PRIO_PROCESS, PRIO_PGRP, PRIO_USER, LOCK_SH,

10125 2001-03-08 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
10127 * ramap.c (racp): Removed optimization which caused array copying
10128 to fail if the two arrays shared storage. Re-inserted the IVDEP
10129 macros removed in the change of 2000-03-09. (Don't really have a
10130 complete grasp of what they are for, but they seem to be necessary
10131 on Crays. This needs testing!) Thanks to Miroslav Silovic.
10133 * hash.c (scm_string_hash): Don't downcase characters.
10135 2001-03-07 Mikael Djurfeldt <mdj@linnaeus.mit.edu>

10150 (*.doc): Add dependency on guile-snarf.awk.in.

10153 SCM_SNARF_DOCSTRING_END. Skip lines "# NN ..." in the

10166 about the expected type with the wrong-type-arg error message.

10169 a C level bug that can't be fixed from scheme anyway.
10171 2001-03-05 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
10173 * eval.c (scm_m_letstar): Removed check for duplicate bindings.
10174 Duplicate bindings are OK in a let* since a let* is semantically
10175 equivalent to a nested set of let:s.
10177 2001-03-05 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
10179 * print.c (scm_print_options): Fixed texinfo in docstring.
10181 * net_db.c (scm_getserv, scm_getproto, scm_getnet): Return #f if
10182 the underlying functions getservent, getprotoent or getnetent
10183 return NULL instead of signalling an error.

10187 * socket.c (scm_fill_sockaddr): don't allow buffer overflows when
10188 taking an unexpectedly large filename for an AF_UNIX socket from

10192 former and adjusted the latter.
10193 (scm_socket, scm_socketpair): cosmetic changes.

10195 size_t as socklen_t substitute. don't restrict args/return values
10196 to INUM: allow full range of int or size_t.
10197 (scm_fill_sockaddr): check arguments before allocating memory, to
10198 avoid leakage. use malloc, not scm_must_malloc.
10199 (scm_connect, scm_bind, scm_sendto): use int, not size_t as socklen_t
10200 substitute. free the sockaddr structure before throwing an error.
10201 (scm_init_add_buffer): procedure removed, together with its static
10202 buffer scm_addr_buffer, which wouldn't be thread safe. instead,
10203 define a macro MAX_ADDR_SIZE and declare the buffer where needed.
10204 (scm_accept, scm_getpeername, scm_getsockname, scm_recvfrom,
10205 scm_sendto): use a local buffer instead of scm_addr_buffer.
10206 adjust for new SCM_SOCK_FD_TO_PORT. use int for address size,
10208 (scm_recvfrom): set addr->sa_family to AF_UNSPEC before the recvfrom
10209 call to detect whether recvfrom could be bothered to set the address.
10210 (scm_init_socket): don't call scm_init_addr_buffer.

10261 (scm_c_improper_memq): New function.
10262 (scm_m_lambda): Check for duplicate arguments.
10263 (scm_ceval, scm_deval): When executing a body: only cons a new
10264 toplevel environment frame when it is different from the
10265 existing one; use EVALCAR instead of SIDEVAL so that we can properly
10266 check for empty combinations; use SCM_EVALIM2 for the same reason
10267 in the non-toplevel loop.
10268 (nontoplevel_cdrxnoap, nontoplevel_cdrxbegin, nontoplevel_begin):
10269 New labels with the meaning of their non-"nontoplevel" partners,
10270 but they are used when it is known that the body is not evaluated at
10272 (scm_apply, scm_dapply): use SCM_EVALIM2 to get proper error
10273 reporting for empty combinations.

10325 2001-02-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
10327 * __scm.h (SCM_ASSERT_TYPE): Add missing macro parameter.
10328 (Obviously nobody compiles with SCM_RECKLESS defined...)
10330 * validate.h (SCM_ASSERT_RANGE): Use the argument number.
10332 2001-02-23 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
10334 * ports.c, ports.h (scm_c_read, scm_c_write): New functions.
10336 * ports.h (SCM_READ_BUFFER_EMPTY_P): New macro.

10340 * numbers.c (scm_two_doubles, scm_sys_expt, scm_sys_atan2,
10341 scm_make_polar): Rename arguments `z1' and `z2' to `x' and `y',
10342 since use of `z' suggests that the arguments may be complex.
10344 * goops.c (scm_make), numbers.c (scm_sys_expt): Fix docstring
10347 2001-02-23 Neil Jerram <neil@ossau.uklinux.net>
10349 * dump.c (scm_binary_write, scm_binary_read), eval.c

10354 2001-02-22 Marius Vollmer <mvo@zagadka.ping.de>
10356 * load.c (load): Use scm_primitive_eval_x instead of scm_i_eval_x.
10358 * goops.c (scm_add_method, DEFVAR): Use scm_eval instead of
10360 (make_class_from_template): Do not bother to set the current
10361 module around the call to DEFVAR, scm_eval takes care of that.
10362 (scm_init_goops): Make scm_module_goops and
10363 scm_goops_lookup_closure permanent objects.
10365 * eval.c (scm_ceval, scm_deval): When evaluating expressions on
10366 top level, create a fresh top-level environment for each
10367 expression instead of mutating the exisint frame. This is
10368 important when that frame is closed over.
10370 * numbers.c (s_scm_logior) [SCM_DIGSTOOBIG]: Also use
10371 SCM_DIGSPERLONG instead of DIGSPERLONG.
10373 2001-02-21 Marius Vollmer <mvo@zagadka.ping.de>
10375 * eval.c (scm_ceval, scm_deval): Check for wrong number of args
10376 before applying arrow procedure in `cond' and before applying
10377 receiver procedure in call-with-current-continuation.
10378 (scm_i_eval): Do not invoke scm_copy_tree in argument in SCM_XEVAL
10379 macro. The argument is expanded more than one time.
10381 * numbers.c (scm_logior) [SCM_DIGSTOOBIG]: Correctly use
10382 SCM_BIGDIG instead of BIGDIG. Thanks to Steven G. Johnson!
10384 2001-02-20 Marius Vollmer <mvo@zagadka.ping.de>
10386 * guile-doc-snarf.in, guile-func-name-check.in: Added copyright

10428 (scm_release_arbiter): Added texinfo markup to docstrings.
10429 Changed `Returns' to `Return'.
10430 (arbiter_print): Changed SCM_CDR to SCM_SMOB_DATA.
10432 2001-02-16 Neil Jerram <neil@ossau.uklinux.net>

10506 2001-02-13 Marius Vollmer <marius.vollmer@uni-dortmund.de>
10508 * gc_os_dep.c: Do not include <linux/version.h>. It makes no
10509 sense to compile for a specific kernel version. Do not include
10510 <asm/signal.h> while defining __KERNEL__. This hack should no
10511 longer be needed and caused problems.
10513 2001-02-13 Marius Vollmer <mvo@zagadka.ping.de>
10515 * eval.c (scm_ceval, scm_deval): use `SIDEVAL' instead of

10528 * modules.h. modules.c (scm_current_module_lookup_closure): New
10531 * eval.h (scm_primitive_eval, scm_primitive_eval_x): New
10533 (scm_i_eval, scm_i_eval_x, scm_eval, scm_eval_x): Changed argument
10534 names to better reflect their meaning.
10536 * eval.c (scm_ceval, scm_deval): Recognize when `begin' is being
10537 evaluated at top-level and synronize lookup closure before
10538 executing every subform.
10539 (scm_primitve_eval_x, scm_primitive_eval): New functions.
10540 (scm_eval_x, scm_eval): Reimplement in terms of
10541 scm_primitive_eval_x and scm_primitive_eval, respectively.
10543 2001-02-09 Marius Vollmer <mvo@zagadka.ping.de>
10545 * macros.c (scm_macro_name, scm_macro_transformer): Use

10561 * ports.c (scm_unread_char): Take an optional argument.
10563 2001-02-08 Marius Vollmer <marius.vollmer@uni-dortmund.de>
10565 * modules.h (scm_selected_module, scm_current_module): Renamed
10566 scm_selected_module to scm_current_module to synchronize Scheme
10568 (scm_select_module, scm_set_current_module): Likewise. Changed
10571 * ports.c (scm_port_for_each): Make a snapshot of the port table
10572 before iterating over it. The table might change while the user
10573 code is running. With the snapshot, the user can depend on the
10574 fact that each port that existed at the start of the iteration is
10575 encountered exactly once. (ice-9 popen) depends on this.
10577 2001-02-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
10579 * strings.h (SCM_STRING_MAX_LENGTH): New macro.
10581 * strings.c (scm_makstr, scm_take_str, scm_make_string): Added
10582 range checking for the size parameter. Thanks to Martin
10583 Grabmueller for the hint.

10586 deferring unnecessary.
10588 * vectors.c (scm_make_vector): Fixed range checking.
10590 2001-02-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
10592 * vectors.h (SCM_VECTOR_MAX_LENGTH): New macro.
10594 * vectors.c (scm_make_vector, scm_c_make_vector): Improved the
10595 checking of the size parameter for type correctness and valid
10596 range. Thanks to Rob Browning for reporting the problem. Instead
10597 of deferring interrupts, scm_remember_upto_here_1 is used.
10599 2001-02-05 Keisuke Nishida <kxn30@po.cwru.edu>
10601 * dump.c (scm_store_cell_object, scm_restore_cell_object): Removed.

10622 (keyword_undump): Renamed from keyword_alloc.
10623 (scm_init_keywords): Set keyword_dump and keyword_undump.
10625 2001-02-03 Michael Livshin <mlivshin@bigfoot.com>
10627 * gc.c (DOUBLECELL_ALIGNED_P): new macro, a better-named analog of
10628 the deprecated SCM_DOUBLE_CELLP.
10630 * tags.h (SCM_DOUBLE_CELLP): deprecated.
10632 2001-02-02 Keisuke Nishida <kxn30@po.cwru.edu>
10634 * dump.c, dump.h: New files.

10901 from Matthias Köppe:
10903 * objects.h (SCM_SET_ENTITY_SETTER): new macro. SCM_ENTITY_SETTER
10904 casts its result, so doesn't yield an lvalue per ANSI C.

10907 SCM_SET_ENTITY_SETTER.
10908 (clear_method_cache): use SCM_SET_ENTITY_PROCEDURE.

10921 * validate.h (SCM_VALIDATE_SUBSTRING_SPEC_COPY): new macro.
10922 * ioext.c (scm_read_string_x_partial, scm_read_delimited_x),
10923 socket.c (scm_recvfrom): use the new macro, plus minor docstring
10925 * ioext.c (scm_read_string_x_partial): don't crash if -1 is supplied
10926 for fdes. if current input port is used, check that it's a file
10929 2001-01-06 Gary Houston <ghouston@arglist.com>
10931 * ioext.c (scm_read_string_x_partial): new procedure, implements

10946 (GUARDIAN_LIVE, GUARDIAN_ZOMBIES, GUARDIAN_NEXT): deleted.
10947 (add_to_live_list): takes a `guardian_t *' now, not SCM.
10948 (guardian_print): print more info.
10949 (guardian_apply): check if the guardian is destroyed, and throw an
10950 error if so. take one more optional argument `throw_p'.
10951 (scm_guard): depending on the value of `throw_p', return a boolean
10953 (scm_get_one_zombie): remove redundant property test.
10954 (guardian_t): represent the various (currently 3, I hope nothing
10955 more gets added) boolean fields as bit flags.
10956 (scm_guardian_destroyed_p, scm_guardian_greedy_p): new predicates.

10964 * fports.c (fport_write): bugfix: handle short writes for
10965 unbuffered ports too. optimize the buffered case by minimizing
10966 the number of write/flush calls.
10967 (write_all): new helper procedure.
