28 * numbers.c, numbers.h (scm_i_clonebig): Remove static, so can use in
31 * numbers.c (scm_logior): Must scm_i_normbig results as per scm_logand,
32 because OR-ing bits into a negative can reduce the value to an inum.
34 * numbers.c (scm_num_eq_p): On 64-bit systems, be careful about
35 casting inum to double since that can lose precision.
37 2005-03-10 Marius Vollmer <marius.vollmer@uni-dortmund.de>

52 scm_after_gc_c_hook here.
53 (scm_gc_for_new_cell): Set scm_gc_running_p here and run the
54 scm_after_gc_c_hook when a full GC has in fact been performed.
55 (scm_i_expensive_validation_check): Call scm_gc, not scm_i_gc.

120 SCM_CRITICAL_SECTION_END): Moved here from threads.h since now
121 they also block/unblock execution of asyncs and call
122 scm_async_click which is declared in async.h but threads.h can not
123 include async.h since async.h already includes threads.h.

125 use of the SCM_CRITICAL_SECTION_* macros.
126 (scm_i_critical_section_mutex): Make it a recursive mutex so that

163 Big merge from the mvo-thread-cleanup branch. The main changes
166 - The dynamic roots functionality has been split into dynamic
167 states and continuations barriers. Fluids have been
168 reimplemented and can now be garbage collected.
170 - Initialization of Guile now works in a multi-thread friendly
171 manner. Threads can freely enter and leave guile mode.
173 - Blocking on mutexes or condition variables or while selecting
174 can now be reliably interrupted via system asyncs.
176 - The low-level threading interface has been removed.

408 the prototypical examples mentioned in the old reference manual.
409 Instead keep the old semantics of dispatching on type. (Yes, this

421 integer-expt and multiply/divide. Inexacts and fractions no longer

446 * posix.c (scm_setlocale): Force errno=EINVAL for an error, since
447 POSIX and C99 don't document errno being set. Reported by Bruno
449 (scm_flock): Update docstring from manual.
451 * random.c (scm_i_init_rstate): Compare w to -1 not 0xffffffffUL, now

479 scm_class_unknown, scm_port_class, scm_smob_class,
480 scm_no_applicable_method, scm_class_of): Moved from objects to
481 goops since they are only useable once goops has been loaded.
482 (scm_classes_initialized): Removed.
483 (scm_class_of): Do not check it.

1014 Enclosed arrays are now their own smob. This has been done to
1015 make the code more explicit about them and to prepare for the time
1016 when generalized vectors include arbitrary one-dimensional
1017 arrays. (Uptonow, enclosed arrays have been recognized by their
1018 use of an array as their storage 'vector'. When all generalized
1019 vectors are allowed as storage, including one-dimensional arrays,
1020 this will no longer work.)

1032 (scm_make_enclosed_array): Use it.
1033 (scm_make_ra): Reimplemented in terms of scm_i_make_ra.

1035 instead of scm_uniform_vector_length.

1037 (scm_i_cvref): New, doing the job of scm_cvref.
1038 (scm_cvref): Use scm_i_cvref.
1039 (scm_array_ref): Do not accept non-arrays when no indices are
1040 given. Use scm_i_cvref to do the actual access.

1052 Added "a" and "b" for strings and bitvectors, resp.
1053 (scm_i_tag_to_prototype, scm_i_tag_to_creator): Renamed former to

1059 (scm_init_unif): Initialize scm_tc16_enclosed_array smob.
1060 Use scm_i_print_array as printer for scm_tc16_array.

1064 * ramap.c (cind): Changed second arg to be pointer to long instead
1066 (scm_ramapc): Allocate index vector with scm_malloc and not as
1067 uniform vector. Wrap it in a frame so that it gets properly freed.
1068 (scm_array_index_map_x): Likewise.
1070 * unif.c: Changed all uses of scm_array_prototype to

1074 in terms of scm_uniform_vector_read_x and

1095 handle generalized vectors, only uniform numeric vectors.

1287 First cut at integrating uniform vectors from srfi-4 with the rest
1288 of Guile. This change replaces scm_tc7_byvect with a s8 uniform

1409 sort and was thus very slow. Thanks to Rolan Orre for reporting

1739 * script.c (scm_compile_shell_switches): Use
1740 scm_from_locale_string instead of scm_makfrom0str.

1802 value" insetad of an "Unbound" one for variables that are found
1803 but still contain SCM_UNDEFINED.

1806 expects a null-terminated string in the locale encoding, but
1807 scm_i_string_writable_chars doesn't give that. Fixed by letting

1809 the result back into tmpl.

1905 for speed on i386, otherwise using mutex.
1907 * eq.c (scm_equal_p): Remove real==fraction and fraction==real, they
1908 must be #f according to R5RS. (equal? follows eqv?, and for eqv? an
1909 exact and inexact is #f.)
1911 * fports.c (fport_print): Use scm_ttyname instead of ttyname directly,
1912 to get thread safety of scm_ttyname.
1914 * ports.c (ttyname): Remove prototype, unused.

1921 * load.c (scm_init_load_path): Do not pass NULL to
1922 scm_to_locale_string, which would happen when GUILE_LOAD_PATH is
1923 not set. Thanks to Bill Schottstaedt.

1943 * ioext.c (scm_fdopen): Use scm_i_fdes_to_port together with
1944 scm_i_mode_bits to avoid accessing internals of SCM string from C.
1946 * filesys.c (STRING_SYSCALL, STRING2_SYSCALL): New helper macros.
1947 Use them instead of SCM_SYSCALL when one or two strings need to be
1948 converted into locale strings.

1950 (scm_rename): Use it.
1951 (scm_readlink, scm_copy_file): Convert SCM strings to locale
1952 strings instead of accessing their internals.
1953 (scm_basename, scm_dirname): Use SCM_I_STRING_CHARS and
1954 SCM_I_STRING_LENGTH instead of SCM_STRING_CHARS and
1957 * extensions.c (load_extension): Convert lib and init to locale

1973 SCM string as argument.
1975 * ports.c (scm_i_void_port): New, like scm_void_port but take mode
1976 bits directly instead of C string.
1977 (scm_void_port): Implement using above.
1978 (scm_sys_make_void_port): Use scm_i_void_port together with
1979 scm_i_mode_bits to avoid accessing internals of SCM string.
1981 * strings.h, strings.c (scm_i_get_substring_spec): New.
1983 * socket.c, rw.c, deprecated.h, validate.h
1984 (SCM_VALIDATE_STRING_COPY): Deprecated. Replaced all uses with
1985 SCM_VALIDATE_STRING plus SCM_I_STRING_CHARS or
1986 scm_to_locale_string, etc.
1987 (SCM_VALIDATE_SUBSTRING_SPEC_COPY): Deprecated. Replaced as
1988 above, plus scm_i_get_substring_spec.

1993 SCM_I_STRING_CHARS, SCM_I_STRING_UCHARS, and SCM_I_STRING_LENGTH
1994 instead of SCM_STRING_CHARS, SCM_STRING_UCHARS, and
1995 SCM_STRING_LENGTH, respectively. Also, replaced scm_return_first
1996 with more explicit scm_remember_upto_here_1, etc, or introduced
1997 them in the first place.
1999 * posix.c (WITH_STRING): New helper macro. Use it where one
2000 locale string is needed for a short piece of code.

2010 * load.c (scm_primitive_load_path): Do not check for absolute
2011 filenames when scm_sys_search_load_path returns false, which will
2012 return absolute filenames unchanged.
2014 2004-08-11 Marius Vollmer <mvo@zagadka.de>
2016 * gc.c, procprop.c (scm_init_storage, scm_stand_in_procs,
2017 scm_stand_in_proc): Use a hastable for scm_stand_in_procs instead
2018 of an alist. Thanks to Matthias Koeppe!
2020 2004-08-10 Marius Vollmer <marius.vollmer@uni-dortmund.de>
2022 * strings.h, deprecated.h (SCM_STRING_COERCE_0TERMINATION_X):
2023 Moved from string.h to deprecated.h.
2025 * deprecated.c, deprecated.h (SCM_CHARS, SCM_LENGTH): Removed.
2027 * strings.h, strings.c (SCM_MAKE_STRING_TAG): Renamed to
2028 SCM_I_MAKE_STRING_TAG, changed all uses.
2029 (SCM_STRING_CHARS, SCM_STRING_UCHARS, SCM_STRING_LENGTH): Renamed
2030 to SCM_I_STRING_CHARS, SCM_I_STRING_UCHARS, and SCM_I_LENGTH
2031 respectively. For a short time, the old names are still there as
2032 aliases. Not all uses have been changed yet, but the ones in
2034 (SCM_STRING_MAX_LEN): Do not hardcode to 24 bits, compute from
2036 (scm_is_string, scm_from_locale_string, scm_from_locale_stringn,
2037 scm_take_locale_string, scm_take_locale_stringn,
2038 scm_to_locale_string, scm_to_locale_stringn,
2039 scm_to_locale_stringbuf): New.
2040 (scm_c_string2str, scm_c_substring2str): Deprecated by moving to
2041 deprecated.[hc]. Implemented in terms of the new functions above.
2042 (scm_take_str, scm_take0str, scm_mem2string, scm_str2string,
2043 scm_makfrom0str): Reimplemented in terms of the new functions from

2047 to replace similar code from posix.c, simpos.c, and dynl.c.
2048 (scm_string_append): Use memcpy instead of explicit loop. Do not
2049 use register keyword. Use plain 'char' instead of 'unsigned
2052 * strports.c (scm_mkstrport): Use SCM_I_STRING_UCHARS instead of
2053 SCM_STRING_UCHARS. Use SCM_I_STRINGP instead of SCM_STRINGP.
2055 * strop.c (scm_i_index): Replaced SCM_STRINGP, SCM_STRING_CHARS,
2056 and SCM_STRING_LENGTH with SCM_I_STRINGP, SCM_I_STRING_CHARS, and
2057 SCM_I_STRING_LENGTH, respectively. Pass string object directly,
2058 not as a pointer. Use scm_remember_upto_here_1 to protect it.
2060 * read.c (scm_input_error): Use a SCM value for 'fn', not a C
2061 string. This avoids a conversion round-trip.
2063 * gh_data.c: Replaced SCM_STRINGP, SCM_STRING_CHARS, and
2064 SCM_STRING_LENGTH with SCM_I_STRINGP, SCM_I_STRING_CHARS, and
2065 SCM_I_STRING_LENGTH, respectively.

2068 * environments.c: Instead calling scm_puts on the SCM_STRING_CHARS
2069 of a string, call scm_display on the string itself.

2073 * stime.c, socket.c, simpos.c, procs.c, posix.c, ports.c,
2074 net_db.c, fports.c, filesys.c, eval.c, deprecation.c, dynl.c:

2079 * simpos.c, posix.c (allocate_string_pointers, environ_list_to_c):
2080 Removed, replaced all uses with scm_i_allocate_string_pointers.

2085 scm_internal_parse_path.
2086 (scm_search_path): Rewritten string handling part of the code in
2087 terms of scm_to_locale_stringbuf and so that it is thread safe.
2089 * error.c (scm_error_scm): Throw directly instead of calling
2090 scm_error, this avoids the back and forth conversion of SUBR and
2091 MESSAGE and also plugs a memory leak.
2092 (scm_error): Call scm_error_scm.
2094 * backtrace.c: Replaced SCM_STRINGP with scm_is_string.
2095 (display_header): Print FNAME when it is true, not
2096 merely when it is a string.
2098 * strings.h (SCM_SET_STRING_LENGTH, SCM_SET_STRING_CHARS): Removed
2099 unceremoniously. They were unused by Guile itself, and external
2100 use should stop immediately.
2103 2004-08-10 Marius Vollmer <mvo@zagadka.de>
2105 * numbers.h, number.c, deprecated.h, deprecated.c (scm_round,
2106 scm_truncate): Renamed to scm_c_round and scm_c_truncate;
2107 deprecated versions installed in deprecated.h and deprecated.c.
2110 2004-08-06 Rob Browning <rlb@defaultvalue.org>
2112 * net_db.c (scm_resolv_error): don't cause an exception while
2113 trying to throw an exception -- call scm_misc_error with correct
2114 arguments. The previous arguments needed a format escape that
2115 wasn't in any of the format strings.
2117 2004-08-06 Kevin Ryde <user42@zip.com.au>
2119 * ramap.c (scm_array_fill_x): For byvect char fill, force signed char
2120 so as not to depend on signedness of plain char. For byvect range
2121 check, throw out-of-range rather than wrong-type-arg.
2123 * unif.c (scm_uniform_vector_ref, scm_array_set_x): For byvect, force
2124 signed byte range checks by using scm_to_schar and scm_from_schar,

2132 guaranteed if multiple threads compete to unlock.
2133 Update docstrings per doc/ref/api-scheduling.texi.
2135 * filesys.c (scm_copy_file): Use fstat on the input fd rather than
2136 stat on the filename, to be certain a file rename can't mean we get
2137 info on one filesystem object but open another. This fstat usage is
2138 similar to Emacs copy-file.
2140 * posix.c (scm_setgroups): Enhance docstring, per doc/ref/posix.texi.
2142 * simpos.c (scm_system_star): Change scm_from_long to scm_from_int on
2143 SIGINT and SIGQUIT, since those values are ints.

2201 scm_num2ulong_long): Discouraged by moving to discouraged.h and
2202 discouraged.c and reimplementing in terms of scm_from_* and

2216 and current usage and migration.
2218 2004-07-31 Kevin Ryde <user42@zip.com.au>

2275 (scm_to_signed_integer, scm_to_unsigned_integer,
2276 scm_from_signed_integer, scm_from_unsigned_integer): Generate via
2277 conv-integer.i.c and conv-uinteger.i.c, as well.
2279 * number.h (scm_to_ssize_t, scm_to_size_t): Use the new

2329 (ipv6_num_to_net, scm_to_ipv6): Renamed ipv6_num_to_net to
2330 scm_to_ipv6 and added type and range checking, for converting from
2331 an IPv& byte-wise address to a SCM integer. Changed all uses.
2332 (bignum_in_ipv6_range_p, VALIDATE_INET6): Removed, their function
2333 is now done by scm_to_ipv6.
2335 * numbers.c (scm_to_signed_integer, scm_to_unsigned_integer): dot
2336 not accept inexact integers.
2338 * validate.h, deprecated.h (SCM_VALIDATE_INUM,
2339 SCM_VALIDATE_INUM_COPY, SCM_VALIDATE_BIGINT,
2340 SCM_VALIDATE_INUM_MIN, SCM_VALIDATE_INUM_MIN_COPY,
2341 SCM_VALIDATE_INUM_MIN_DEF_COPY,SCM_VALIDATE_INUM_DEF,
2342 SCM_VALIDATE_INUM_DEF_COPY, SCM_VALIDATE_INUM_RANGE,
2343 SCM_VALIDATE_INUM_RANGE_COPY): Deprecated because they make the
2344 fixnum/bignum distinction visible. Changed all uses to
2345 scm_to_size_t or similar.
2347 2004-07-09 Marius Vollmer <marius.vollmer@uni-dortmund.de>
2349 * cpp_cnvt.awk: Use scm_from_int instead of SCM_MAKINUM.
2351 2004-07-10 Kevin Ryde <user42@zip.com.au>
2353 * hash.c (scm_hashq, scm_hashv, scm_hash): Restrict to size>=1 rather
2354 than size>=0, since 0<=hash<size cannot be satisfied for size==0, and
2355 such a size causes divide-by-zeros in scm_hasher.
2357 * regex-posix.c (scm_make_regexp): Free rx on error, to avoid memory
2360 2004-07-08 Marius Vollmer <marius.vollmer@uni-dortmund.de>
2362 * numbers.c (scm_is_signed_integer, scm_is_unsigned_integer):
2363 Rewritten using the same logic as scm_to_signed_integer and
2364 scm_to_unsigned_integer, respectively, which is better(tm). Also,
2365 use CHAR_BIT instead of hardcoding 8.
2366 (LLONG_MIN, LLONG_MAX, ULLONG_MAX): Removed and used
2367 SCM_I_LLONG_MIN etc. instead.
2369 * numbers.h (SCM_MAKINUM, SCM_I_MAKINUM): Renamed SCM_MAKINUM to
2370 SCM_I_MAKINUM and changed all uses.
2371 * deprecated.h, deprecated.c (SCM_MAKINUM): Newly deprecated.
2373 * gen-scmconfig.c (SCM_I_LLONG_MIN, SCM_I_LLONG_MAX,
2374 SCM_I_ULLONG_MAX): Instead of hard-coding the numbers, compute
2375 them by assuming twos-complement.
2377 2004-07-07 Marius Vollmer <marius.vollmer@uni-dortmund.de>
2379 * gen-scmconfig.h.in: Added all the new SCM_I_GSC_*_LIMITS that
2380 configure now produces.
2381 * gen-scmconfig.c: Use them to output SCM_T_INT8_MIN, etc
2382 definitions, giving the limits of the integer types defined by
2383 Guile. Also, output a hard coded SCM_I_LLONG_MIN, etc since
2384 LLONG_MIN or LONG_LONG_MIN is hard to get at.
2386 * numbers.h (scm_to_short, scm_to_ushort): It's SHRT_MIN, etc, not
2388 (scm_to_size_t): Use SIZE_MAX instead of cooking our own.
2389 (scm_to_long_long, scm_to_ulong_long, scm_to_int8, scm_to_uint8,
2390 scm_to_int16, scm_to_uint16, scm_to_int32, scm_to_uint32,
2391 scm_to_int64, scm_to_uint64, scm_to_intmax, scm_to_uintmax,

2393 scm_from_uint8, scm_from_int16, scm_from_uint16, scm_from_int32,
2394 scm_from_uint32, scm_from_int64, scm_from_uint64, scm_from_intmax,
2395 scm_from_uintmax): New.
2397 2004-07-06 Marius Vollmer <marius.vollmer@uni-dortmund.de>
2399 * tags.h (scm_is_eq): New.
2401 * deprecated.h, boolean.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOL,
2402 SCM_NEGATE_BOOL, SCM_BOOLP): Deprecated by moving into
2403 "deprecated.h". Replaced all uses with scm_is_false, scm_is_true,
2404 scm_from_bool, and scm_is_bool, respectively.
2406 * boolean.h (scm_is_bool): Fix bug in prototype.
2407 (scm_from_bool): The argument is "x" not "f", stupid.
2409 * boolean.c (scm_is_bool): Fix typo.
2411 * numbers.h, numbers.c (scm_is_integer, scm_is_signed_integer,
2412 scm_is_unsigned_integer, scm_to_signed_integer,
2413 scm_to_unsigned_integer, scm_to_schar, scm_to_uchar, scm_to_char,

2418 scm_from_ssize_t, scm_is_real, scm_to_double, scm_from_double):
2421 2004-07-05 Marius Vollmer <marius.vollmer@uni-dortmund.de>
2423 * boolean.h, boolean.c (scm_is_true, scm_is_false, scm_from_bool,
2426 2004-06-27 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
2428 * backtrace.c (display_expression, display_frame): Call
2429 scm_i_unmemoize_expr for unmemoizing a memoized object holding a
2430 single memoized expression.
2432 * debug.c (memoized_print): Don't try to unmemoize the memoized
2433 object, since we can't know whether it holds a single expression
2436 (scm_mem_to_proc): Removed check for lambda expression, since it
2437 was moot anyway. Whoever uses these functions for debugging
2438 purposes should know what they do: Creating invalid memoized code
2439 will cause crashes, independent of whether this check is present
2442 (scm_proc_to_mem): Take the closure's code as it is and don't
2443 append a SCM_IM_LAMBDA isym. To allow easier debugging, the
2444 memoized code should not be modified.
2446 * debug.[ch] (scm_unmemoize, scm_i_unmemoize_expr): Removed
2447 scm_unmemoize from public use, but made scm_i_unmemoize_expr
2448 available as a guile internal function instead. However,
2449 scm_i_unmemoize_expr will only work on memoized objects that hold
2450 a single memoized expression. It won't work with bodies.
2452 * debug.c (scm_procedure_source), macros.c (macro_print), print.c
2453 (scm_iprin1): Call scm_i_unmemocopy_body for unmemoizing a body,
2454 i. e. a list of expressions.
2456 * eval.c (unmemoize_exprs): Drop internal body markers from the
2457 output during unmemoization.
2459 * eval.[ch] (scm_unmemocopy, scm_i_unmemocopy_expr,
2460 scm_i_unmemocopy_body): Removed scm_unmemocopy from public use,
2461 but made scm_i_unmemocopy_expr and scm_i_unmemocopy_body available
2462 as guile internal functions instead. scm_i_unmemoize_expr will
2463 only work on a single memoized expression, while
2464 scm_i_unmemocopy_body will only work on bodies.
2466 2004-06-21 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
2468 * eval.c (unmemoize_exprs): Handle semi-memoized code.
2470 (scm_cons_source, scm_primitive_eval): Prefer higher level
2471 predicate SCM_FALSEP over SCM_IMP.
2473 2004-06-15 Rob Browning <rlb@defaultvalue.org>
2475 * script.c (scm_shell_usage): minor phrasing change.
2477 * gc_os_dep.c: update ifdefery for macosx.
2478 (scm_get_stack_base): separate result initialization from
2479 declaration to slience warnings with macosx and hp-ux using gcc
2480 3.3. Thanks to Andreas Vögele.
2482 2004-06-13 Han-Wen Nienhuys <hanwen@xs4all.nl>
2484 * eval.c (unmemoize_exprs): use SCM_CONSP for the loop condition.
2486 2004-06-06 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
2488 * list.[ch] (scm_i_finite_list_copy): New internal function to
2489 copy lists that are known to be finite (though not necessarily
2492 * debug.c (scm_procedure_source): Don't have scm_unmemocopy treat
2493 a closure's argument list like an expression of a body.
2495 * eval.c (unmemoize_expression, unmemoize_exprs, unmemoize_and,
2496 unmemoize_begin, unmemoize_case, unmemoize_cond, unmemoize_delay,
2497 unmemoize_do, unmemoize_if, unmemoize_lambda, unmemoize_let,
2498 unmemoize_letrec, unmemoize_letstar, unmemoize_or,
2499 unmemoize_set_x, unmemoize_apply, unmemoize_atcall_cc,
2500 unmemoize_at_call_with_values, unmemoize_future, sym_atslot_ref,
2501 unmemoize_atslot_ref, sym_atslot_set_x, unmemoize_atslot_set_x,
2502 unmemoize_builtin_macro): New static functions and symbols.
2504 (scm_unmemocopy): Rewritten in terms of the above. scm_unmemocopy
2505 now has a slightly different meaning: The memoized form that is
2506 receives as its argument is now interpreted as a sequence of
2507 expressions from a body.
2509 (unmemocar, scm_unmemocar): Since the whole functionality of
2510 unmemocar and scm_unmemocar is not needed any more, scm_unmemocar
2511 has its old content back and is deprecated, while unmemocar has
2514 (SCM_BIT7): Removed.
2516 (CEVAL): For unmemoizing a single expression, call
2517 unmemoize_expression instead of scm_unmemocopy, which now expects
2518 a sequence of body expressions. Eliminated unnecessary empty
2519 environment frame when executing let* forms. Eliminated
2520 unmemoization step from evaluator.
2522 2004-06-02 Marius Vollmer <marius.vollmer@uni-dortmund.de>
2524 * eval.c (scm_macroexp, macroexp): Renamed scm_macroexp to
2525 macroexp and made static. Added new version of scm_macroexp that
2526 emits a deprecation warning and then calls macroexp.
2527 (scm_m_undefine): Issue deprecation warning.
2529 2004-05-30 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
2531 * eval.c (lookup_global_symbol, literal_p, try_macro_lookup):
2532 Modified to make set! work on symbols that represent syntactic
2535 2004-05-26 Han-Wen Nienhuys <hanwen@xs4all.nl>
2537 * gc.h (SCM_CELL_OBJECT_LOC): use SCM_GC_CELL_OBJECT to prevent
2538 compound expression as lvalue errors.
2540 2004-05-24 Marius Vollmer <mvo@zagadka.de>
2542 * dynwind.c (winder_mark): Use SCM_PACK to correctly convert the
2543 WINDER_DATA to a SCM.
2545 2004-05-24 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
2547 * goops.c (compute_getters_n_setters, create_standard_classes,
2548 scm_add_slot): Compute closures by calling scm_i_eval_x on a
2549 lambda expression rather than creating them with scm_closure.
2551 2004-05-22 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
2553 * eval.c (s_macro_keyword, scm_m_set_x): Remove checking for
2554 misplaced syntactic keywords. This will not work unless guile's
2555 defmacro feature is deprecated.
2557 (scm_m_case): Fixed a bug that caused the list of labels to grow
2558 with every case form.
2560 2004-05-19 Kevin Ryde <user42@zip.com.au>
2562 * numbers.c (scm_round_number): For inum and big, just return x. For
2563 real, use scm_round for 2^54-1 etc problems covered there.
2565 * numbers.c (trunc): Remove #define to scm_truncate when the C library
2566 doesn't provide trunc. This was for when `truncate' was done as a
2567 scm_tc7_dsubr, no longer required.
2569 * threads.c (scm_threads_mark_stacks) [SCM_STACK_GROWS_UP]: Correction
2570 to stack marking call, two parameters and no cast on t->base.
2572 2004-05-18 Marius Vollmer <mvo@zagadka.de>
2574 * hashtab.c (rehash_after_gc): Bug fix: properly link the
2575 processed hashtables back into the weak_hashtables list. Thanks
2576 to Bill Schottstaedt!
2578 2004-05-16 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
2580 * eval.c (unmemoize_quote): New static function.
2582 (scm_m_quote, scm_m_atslot_ref, SCM_CEVAL): Changed the byte code
2583 representation of 'quote' and '@slot-ref' to an improper list.
2584 This reduces execution time, the number of cells used to hold the
2585 memoized code, and thus also reduces garbage collection time.
2587 (scm_unmemocopy): Use unmemoize_quote for quote expressions.
2589 (SCM_CEVAL): Changed macro handling to also work with macros that
2590 return improper lists. Added an assertion, that the code returned
2591 by a macro transformer will not lead to cycles in the memoized
2594 2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
2596 No functional change, just rearrangements of functions within the
2599 * eval.c (scm_ilookup, scm_unbound_variable_key,
2600 error_unbound_variable, scm_lookupcar1, scm_lookupcar): Moved to
2601 the definitions used for execution, since that's where they will
2604 2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
2606 * numbers.h (SCM_SLOPPY_FRACTIONP): Removed. It was not used
2607 throughout guile, has not been part of an official release yet,
2608 and the concept of sloppy predicates has never been a good idea.
2610 (SCM_FRACTION_NUMERATOR, SCM_FRACTION_DENOMINATOR,
2611 SCM_FRACTION_SET_NUMERATOR, SCM_FRACTION_SET_DENOMINATOR):
2614 2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
2616 * throw.c (SETJBJMPBUF, SCM_SETJBDFRAME): Add cast to scm_t_bits
2617 to make explicit what happens.
2619 2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
2621 * dynl.c (SET_DYNL_HANDLE): Add cast to scm_t_bits to make
2622 explicit what happens.
2624 * guardians.c (TCONC_IN): Use SCM_SET_CELL_OBJECT_x rather than
2625 SCM_SET_CELL_WORD_x when writing scheme objets to cell elements.
2627 2004-05-11 Marius Vollmer <mvo@zagadka.de>
2629 * scmsigs.c (scm_sigaction_for_thread): Validate that the handler
2630 is indeed a procedure when it isn't a number.
2632 2004-05-10 Marius Vollmer <mvo@zagadka.de>
2634 Convert floating point numbers into strings with an arbitrary
2635 radix. Thanks to Richard Todd!
2637 * numbers.c (FLOBUFLEN): Increase so that radix 2 strings will
2640 (scm_dblprec, fx_per_radix, init_dblprec, init_fx_radix,
2641 number_chars): New, to support variable radices.
2642 (idbl2str): Use above instead of the old base-10 only tables.
2643 (iflo2str): Pass on new RADIX argument to idbl2str.
2644 (scm_number_to_string): Pass radix to iflo2str.
2645 (scm_print_real, scm_print_complex): Explicitly pass radix 10 to
2647 (scm_init_numbers): Call init_dblprec and init_fx_radix for all
2650 2004-05-10 Kevin Ryde <user42@zip.com.au>
2652 * numbers.c (scm_logbit_p): Correction to test above the end of an
2653 inum. Reported by Jan Konecny.
2655 2004-05-06 Marius Vollmer <marius.vollmer@uni-dortmund.de>
2657 * gc.h (scm_t_cell): Fields are now of type SCM instead of
2658 scm_t_bits. Updated all users.
2659 (SCM_GC_CARD_SIZE_MASK): Use SCM_GC_SIZEOF_CARD instead of
2660 duplicating the code.
2661 (SCM_CELL_OBJECT_LOC): New.
2662 (SCM_CARLOC, SCM_CDRLOC): Use it instead of SCM_CELL_WORD_LOC.
2663 (SCM_CELL_WORD_LOC): Moved to "deprecated.h".
2665 * smob.h (SCM_SMOB_DATA_2, SCM_SMOB_DATA_3, SCM_SMOB_FLAGS,
2666 SCM_SET_SMOB_DATA_2, SCM_SET_SMOB_DATA_3, SCM_SET_SMOB_FLAGS,
2667 SCM_SMOB_OBJECT, SCM_SMOB_OBJECT_2, SCM_SMOB_OBJECT_3,

2669 SCM_SMOB_OBJECT_LOC, SCM_SMOB_OBJECT_2_LOC,
2670 SCM_SMOB_OBJECT_3_LOC): New.
2671 * smob.c (scm_i_set_smob_flags): New function.
2673 * dynl.c, dynwind.c, eval.h, fluids.h, futures.h, hashtab.h,
2674 hooks.h, keywords.h, macros.h, macros.c, mallocs.c, mallocs.h,
2675 random.h, regex-posix.h, root.h, srcprop.h, srcprop.c, threads.h:
2676 Use SCM_SMOB_* instead of SCM_CELL_* as appropriate. Use
2677 SCM_SMOB_FLAGS and SCM_SET_SMOB_FLAGS instead of accessing the
2678 zeroth word directly. Use SCM_SMOB_PREDICATE as appropriate.
2680 * numbers.h (SCM_I_BIG_MPZ): Use SCM_CELL_OBJECT_LOC instead of
2681 taking the address of SCM_CELL_WORD_1, the latter being no longer
2684 * variable.h (SCM_VARIABLE_LOC): Use SCM_CELL_OBJECT_LOC instead
2685 of casting SCM_CELL_WORD_LOC.
2687 2004-05-02 Kevin Ryde <user42@zip.com.au>
2689 * eval.c (scm_macroexp): Add prototype, since it's not in eval.h under
2690 --disable-deprecated. Reported by Andreas Vögele.
2692 * filesys.c (_POSIX_C_SOURCE): Define to 199506L to get readdir_r (in
2693 particular on HP-UX). Reported by Andreas Vögele.
2695 * list.c (varargs.h): Remove, leave just stdarg.h which is all the
2696 code has support for. Fixes building with AIX cc, which is ansi but
2697 doesn't define __STDC__. Reported by Keith Crane.
2698 (var_start): Remove macro, this variation no longer required.
2699 (scm_list_n): Use va_start directly.
2701 2004-05-01 Kevin Ryde <user42@zip.com.au>
2703 * continuations.c (scm_dynthrow): Use >= instead of SCM_PTR_GE which
2704 is now gone. Reported by Andreas Vögele.
2706 2004-04-28 Kevin Ryde <user42@zip.com.au>
2708 * backtrace.c (display_frame_expr), numbers.c (XDIGIT2UINT,
2709 mem2uinteger, mem2decimal_from_point, mem2ureal): Cast char to int for
2710 ctype.h tests, to avoid warnings from gcc on HP-UX about char as array
2711 subscript. Reported by Andreas Vögele.
2712 Also cast through unsigned char to avoid passing negatives to those
2713 macros if input contains 8-bit values.
2715 * num2integral.i.c (NUM2INTEGRAL): Under non-BIGMPZ_FITSP case,
2716 corrections to range check for signed numbers. Remove
2717 scm_remember_upto_here_1(num) from these checks, since num is used
2718 subsequently anyway.
2720 * num2integral.i.c (NUM2INTEGRAL): Test BIGMPZ_FITSP with "!= 0" to
2721 avoid warning from gcc 3.4. Reported by Hyperdivision.
2723 * numbers.c (scm_bit_extract): Use min instead of MIN.
2724 (MIN): Remove, this conflicts with similar macro defined by limits.h
2725 on HP-UX. Reported by Andreas Vögele.
2727 * stime.c (_POSIX_C_SOURCE): Define to 199506L to get gmtime_r (in
2728 particular on HP-UX). Reported by Andreas Vögele.
2730 * threads.c (scm_threads_mark_stacks): Correction sizet -> size_t.
2731 Reported by Andreas Vögele.
2733 * threads-plugin.h (SCM_MUTEX_MAXSIZE): Increase to 25*sizeof(long),
2734 for the benefit of hpux11 where pthread_mutex_t is 88 bytes. Reported
2737 2004-04-22 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
2739 * eval.c (s_macro_keyword): New static identifier.
2741 (scm_m_define): Change order to first create binding and
2742 evaluating the expression afterwards.
2744 (scm_m_set_x): Memoize complete set! expression. Only leave
2745 symbols if no binding exists at memoization time. Throw error if
2746 assigning to a syntactic keyword.
2748 (lazy_memoize_variable): New function.
2750 (CEVAL): When execution set!, perform lazy memoization if
2751 unmemoized symbol is detected.
2753 * modules.c (module_variable): Return variables with unbound
2756 * tags.h: Fix comment.
2758 2004-04-25 Kevin Ryde <user42@zip.com.au>
2760 * chars.c (scm_char_upcase, scm_char_downcase, scm_c_upcase,
2761 scm_c_downcase): Use ctype.h toupper and tolower. This will be useful
2762 in 8-bit locales, and ensures consistency with char-upper-case? and
2763 char-lower-case? which already use ctype.h.
2764 (scm_c_upcase_table, scm_c_downcase_table, scm_lowers, scm_uppers):
2766 * chars.c, chars.h, init.c (scm_tables_prehistory): Remove.
2768 * socket.c (VALIDATE_INET6): Correction to bignum_in_ipv6_range_p
2769 call. Reported by Hyperdivision.
2771 * threads.c (scm_yield): Correction, actually call scm_thread_yield.
2772 Reported by Hyperdivision.
2774 * unif.c (s_scm_make_uve): Remove unused local variable. Reported by
2777 2004-04-22 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
2779 Hide the implementation of ilocs and isyms in eval.c.
2781 * deprecated.h (SCM_IFRINC, SCM_ICDR, SCM_IFRAME, SCM_IDIST,
2782 SCM_ICDRP), eval.c (SCM_IFRINC, SCM_ICDR, SCM_IFRAME, SCM_IDIST,
2783 SCM_ICDRP), eval.h (SCM_ICDR, SCM_IFRINC, SCM_IFRAME, SCM_IDIST,
2784 SCM_ICDRP): Deprecated and added to deprecated.h. Moved from
2787 * deprecated.c (scm_isymnames), deprecated.h (scm_isymnames,
2788 SCM_ISYMNUM, SCM_ISYMCHARS), eval.c (SCM_ISYMNUM, isymnames,
2789 scm_unmemocopy, CEVAL), print.c (scm_isymnames), tags.h
2790 (SCM_ISYMNUM, scm_isymnames, SCM_ISYMCHARS): Deprecated
2791 scm_isymnames, SCM_ISYMNUM and SCM_ISYMCHARS and added to
2792 deprecated.[hc]. Moved scm_isymnames from print.c to eval.c and
2793 renamed to isymnames. Moved SCM_ISYMNUM from tags.h to eval.c and
2796 * eval.c (scm_i_print_iloc, scm_i_print_isym), eval.h
2797 (scm_i_print_iloc, scm_i_print_isym), print.c (scm_iprin1):
2798 Extracted printing of ilocs and isyms to guile internal functions
2799 scm_i_print_iloc, scm_i_print_isym of eval.c.
2801 2004-04-22 Kevin Ryde <user42@zip.com.au>
2803 * numbers.c (scm_bit_extract): Use SCM_SRS for signed right shift.
2805 * numbers.c (scm_round): Test for x already an integer, to avoid bad
2806 rounding in x+0.5 when x is a big value already an integer. In
2807 certain hardware rounding cases x+0.5 can give an adjacent integer,
2808 leading to that as the result, when we really just wanted x itself.
2810 2004-04-19 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
2812 * eval.c (scm_unmemocopy): Fixed unmemoization of let*.
2814 (deval_args, CEVAL): Minor improvements: Reduced variable scopes,
2815 added const qualifiers, cast intentionally unused expressions to
2816 void for emphasis, improved comment.
2818 2004-04-18 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
2820 * tags.h (scm_tags, scm_tc8_tags, scm_tc9_flag, scm_tc8_flag,
2821 scm_tc8_isym): Renamed scm_tags to scm_tc8_tags. Renamed
2822 scm_tc9_flag to scm_tc8_flag. Introduced new identifier
2823 scm_tc8_isym. Defined tc8-tags relative to scm_tc3_imm24.
2824 Defined the tc8-tag for flags to be 0x04, which will mean that
2825 SCM_BOOL_F will also have the value 0x04 instead of 0x013c. Due
2826 to the reduced number of bits and the simpler bit pattern for
2827 SCM_BOOL_F, certain machines may be able to use more efficient
2828 processor instructions to deal with SCM_BOOL_F.
2830 (SCM_ITAG9, SCM_MAKE_ITAG9, SCM_ITAG9_DATA): Removed. These have
2831 never been defined in a released version, thus no need to
2834 (SCM_IFLAGP, SCM_MAKIFLAG, SCM_IFLAGNUM): Flags now use tc8
2835 instead of tc9 tags.
2837 (SCM_ISYMP, SCM_MAKISYM, SCM_ISYMNUM): Isyms now use tc8 instead
2840 (SCM_MAKSPCSYM): Removed. It is almost impossible that user code
2841 could have used this definition.
2843 (SCM_IM_AND, SCM_IM_BEGIN, SCM_IM_CASE, SCM_IM_COND, SCM_IM_DO,
2844 SCM_IM_IF, SCM_IM_LAMBDA, SCM_IM_LET, SCM_IM_LETSTAR,
2845 SCM_IM_LETREC, SCM_IM_OR, SCM_IM_QUOTE, SCM_IM_SET_X): Now encoded
2846 as isyms, as special isyms don't exist any more.
2848 2004-04-18 Kevin Ryde <user42@zip.com.au>
2850 * filesys.c (scm_readdir): Use readdir_r when available, for thread
2853 * numbers.c (scm_max, scm_min): For big/real, use SCM_SWAP rather than
2854 explicit swapping code.
2856 2004-04-15 Kevin Ryde <user42@zip.com.au>
2858 * cpp_sig_symbols.in: Add SIGSYS.
2860 * list.c (scm_append_x): Use iterative style, to avoid non-tail
2863 * numbers.c (scm_max, scm_min): For inum/frac, frac/inum, big/frac,
2864 frac/big and frac/frac, use scm_less_p for exact comparison.
2866 * numbers.c (scm_gcd): For inum/big, use mpz_gcd_ui by sharing code
2869 * numbers.c (xisinf): Add a comment about solaris 7 lacking isinf.
2871 2004-04-06 Han-Wen Nienhuys <hanwen@xs4all.nl>
2873 * inline.h (scm_cell): use SCM_GC_CELL_WORD for checking tag.
2875 * chars.h (scm_init_chars): change scm_{upcase,downcase} to
2876 scm_c_{up,down}case.
2877 (SCM_MAKE_CHAR): add (unsigned char) cast. This prevents havoc
2878 when hi-bit ASCII is subjected to SCM_MAKE_CHAR().
2880 2004-04-06 Kevin Ryde <user42@zip.com.au>
2882 * numbers.c (scm_ash): Remove stray "}" in docstring.
2884 * numbers.c (scm_make_ratio): For inum/bignum integer detection, use
2885 x==SCM_MOST_NEGATIVE_FIXNUM explicitly, for clarity and to avoid
2886 calling mpz_cmp_ui in most cases.
2888 * numbers.c (scm_quotient, scm_remainder): In inum/big, use mpz_cmp_ui
2889 for big == abs(most-negative-fixnum) special case.
2890 (abs_most_negative_fixnum): Remove, no longer used.
2892 * scmsigs.c (scm_sigaction_for_thread): Correction to signum range
2893 test, avoids SCM_VECTOR_REF outside bounds of signal_handlers on
2894 calling (sigaction NSIG).
2896 * simpos.c (scm_system_star): Fix execargv memory leak, merge parent
2897 and fork error cases to do this.
2899 2004-04-03 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
2901 * eval.c (CEVAL): Don't distinguish between short and long
2902 instructions when dispatching - just always dispatch on the
2903 instruction code, which is common for short and long instructions.
2904 Further, removed unnecessary goto statements and added comment.
2906 2004-04-03 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
2908 * eval.c (scm_unmemocopy): Don't distinguish between short and
2909 long instructions when dispatching - just always dispatch on the
2910 instruction code, which is common for short and long instructions.
2911 Further, removed unnecessary goto statements, fixed indentation
2912 and replaced SCM_IMP predicates by SCM_NULLP.
2914 2004-04-03 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
2916 * eval.c (scm_lookupcar1, CEVAL): Use SCM_ILOCP instead of
2917 comparison with SCM_ILOC00. In CEVAL, eliminate goto-label
2920 2004-03-31 Kevin Ryde <user42@zip.com.au>
2922 * simpos.c: Include <signal.h> for SIG_IGN and friends.
2924 2004-03-29 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
2926 Introduce scm_debug_mode_p as a replacement for scm_debug_mode and
2929 * debug.h (scm_debug_mode_p, scm_debug_mode, SCM_DEBUGGINGP),
2930 eval.c (scm_debug_mode_p): Deprecated scm_debug_mode and
2931 SCM_DEBUGGINGP. Provided scm_debug_mode_p instead, to have one
2932 single interface that also matches the naming conventions.
2933 Probably scm_debug_mode_p should be part of the private interface
2936 * debug.h (scm_debug_mode_p), backtrace.c (display_error_body),
2937 eval.c (SCM_APPLY, scm_trampoline_0, scm_trampoline_1,
2938 scm_trampoline_2): Change uses of scm_debug_mode or SCM_DEBUGGINGP
2939 to scm_debug_mode_p.
2942 Deprecate direct access to scm_ceval, scm_deval and scm_ceval_ptr:
2944 * eval.h (scm_ceval, scm_deval, scm_ceval_ptr), debug.h
2945 (scm_ceval_ptr): Deprecated. Moved declaration of scm_ceval_ptr
2946 from debug.h to eval.h.
2948 * debug.h (SCM_RESET_DEBUG_MODE): Don't access scm_ceval_ptr any
2949 more, just leave it with setting scm_debug_mode_p, which is
2950 equivalent for practical purposes.
2952 * deprecated.h (SCM_XEVAL, SCM_XEVALCAR): Call scm_i_eval_x
2953 instead of *scm_ceval_ptr. Leave all evaluating to scm_i_eval_x.
2955 * gdbint.c (gdb_eval): Call scm_i_eval_x instead of scm_ceval.
2957 * eval.c (ceval, deval, scm_ceval, scm_deval): Made scm_ceval
2958 static and renamed it to ceval throughout. Provide a new exported
2959 but deprecated function scm_ceval as a wrapper for backwards
2960 compatibility. The same is done for the deval/scm_deval pair of
2963 * eval.c (CEVAL, SCM_CEVAL): Renamed SCM_CEVAL to CEVAL
2964 throughout. Defined CEVAL to ceval or deval, based on compilation
2967 * eval.c (SCM_XEVAL, SCM_XEVALCAR): Dispatch on scm_debug_mode_p
2968 to ceval and deval instead of calling *scm_ceval_ptr.
2970 * eval.c (dispatching_eval): New deprecated static function.
2972 * eval.c (scm_ceval_ptr): Initialized to dispatching_eval in order
2973 to emulate its old behaviour as closely as possible.
2976 Change the evaluator such that only expressions for which pair? is
2977 true are passed to CEVAL, and such that all other expressions are
2978 evaluated outside of CEVAL:
2980 * eval.c (EVAL): New, provided in analogy to EVALCAR. Evaluate an
2981 expression that is assumed to be memoized already. All but
2982 expressions of the form '(<form> <form> ...)' are evaluated inline
2983 without calling an evaluator.
2985 * eval.c (SCM_XEVAL, SCM_XEVALCAR, EVALCAR): Evaluate all but
2986 expressions of the form '(<form> <form> ...)' inline without
2987 calling an evaluator.
2989 * eval.c (scm_i_eval_x, scm_i_eval, scm_ceval, scm_deval): Handle
2990 the special case of unmemoized symbols passed on the top level.
2992 * eval.c (CEVAL): Change calls to CEVAL to EVAL, except where it
2993 is known that the expression passed to CEVAL is of the form
2994 '(<form> <form> ...)'. Remove handling of the tc7-objects, since
2995 now it is known that the input expression of CEVAL is a pair.
2997 2004-03-29 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
2999 * eval.c (is_self_quoting_p): New static function.
3001 (scm_m_quote): Use is_self_quoting_p.
3003 (copy_tree): Corrected typo in comment.
3005 2004-03-28 Han-Wen Nienhuys <hanwen@xs4all.nl>
3007 * eval.c (s_scm_copy_tree): idem.
3009 * list.c (s_scm_filter): remove "pointer" from doc string.
3011 * gc.h (SCM_GC_CELL_TYPE): SCM_GC_CELL_TYPE uses SCM_GC_CELL_OBJECT.
3013 * goops.h (SCM_NUMBER_OF_SLOTS): don't SCM_UNPACK the result.
3015 * backtrace.c ("display_backtrace_body"): SCM_PACK before SCM_EQ_P
3016 (display_frame): idem.
3017 (display_backtrace_file_and_line): idem.
3019 * tags.h (SCM_UNPACK): stricter typechecking on SCM_UNPACK
3022 2004-03-26 Kevin Ryde <user42@zip.com.au>
3024 * filesys.c (scm_getcwd, scm_readlink): Avoid memory leak on errors.
3026 * numbers.c (scm_modulo): For inum/big and big/big, remove test of
3027 big==0 since that never occurs.
3029 * numbers.c, numbers.h (scm_modulo_expt): Renamed from
3030 scm_modular_expt, matching scheme level name `modulo-expt'.
3032 * numbers.c (scm_modular_expt): Return a negative remainder for a
3033 negative divisor, the same as `modulo' does.
3035 2004-03-26 Eric Hanchrow <offby1@blarg.net>
3037 * numbers.c, numbers.h (scm_modular_expt): New function.
3039 2004-03-25 Kevin Ryde <user42@zip.com.au>
3041 * numbers.c (scm_min, scm_max): Correction to big/real and real/big,
3042 return inexact as required by r5rs.
3044 2004-03-24 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
3046 * eval.c: Separated some definitions relevant for execution from
3047 the memoization part of the file.
3049 (copy_tree): New static function
3051 (scm_copy_tree): Rewritten to fix two kinds or bugs: First, cyclic
3052 structures are detected now and will lead to an exception instead
3053 of forcing guile to run in an endless loop, using up all the
3054 system's memory. Second, arrays in the cdr of an improper list
3055 are now copied. See the new test cases in eval.test.
3057 2004-03-24 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
3059 * posix.c (scm_gethostname): Make sure len is initialised before
3060 it is used. Restructured to (hopefully) represent possible
3061 configurations more clearly in the code. Added unwind handler.
3063 2004-03-23 Kevin Ryde <user42@zip.com.au>
3065 * posix.c (scm_gethostname): Use sysconf(_SC_HOST_NAME_MAX) and/or
3066 MAXHOSTNAMELEN when available.
3068 2004-03-21 Marius Vollmer <mvo@zagadka.de>
3070 * read.c (skip_scsh_block_comment): Also recognize '\r' as a line
3071 terminator. Rewritten the logic as a state machine, I must have
3072 been doing too much VHDL lately...
3074 * eval.c (scm_ceval, scm_deval): Explicitely evaluate ports to
3075 themselves. Thanks to Han-Wen Nienhuys!
3077 * list.c: Changed docstrings so that they no longer talk about
3078 returning 'pointers' to something.
3080 2004-03-20 Han-Wen Nienhuys <hanwen@xs4all.nl>
3082 * gc.c: remove set_debug_cell_accesses! when
3083 SCM_DEBUG_CELL_ACCESSES is not defined. Scheme source code should
3084 use (if (defined? 'set-debug-cell-accesses!) .. ) to switch on
3085 debugging conditionally.
3087 2004-03-21 Kevin Ryde <user42@zip.com.au>
3089 * stime.c (scm_gmtime): Use gmtime_r when available, for thread safety.
3091 2004-03-20 Kevin Ryde <user42@zip.com.au>
3093 * posix.c (scm_gethostname): Preserve errno across free() call.
3095 2004-03-18 Han-Wen Nienhuys <hanwen@xs4all.nl>
3097 * gc-card.c (sweep_card): use SCM_GC_SET_CELL_WORD for setting
3100 2004-03-14 Kevin Ryde <user42@zip.com.au>
3102 * stime.c: Define _GNU_SOURCE for strptime prototype from glibc.
3103 (strptime): Use HAVE_DECL_STRPTIME for when to give own prototype.
3105 2004-03-07 Kevin Ryde <user42@zip.com.au>
3107 * stime.c (scm_gmtime): Return bd_time->tm_zone when available, rather
3109 (filltime): Make zname parameter "const".
3111 2004-03-03 Mikael Djurfeldt <mdj@chunk.mit.edu>
3113 * threads.c, threads.h (scm_c_scm2thread): New function.
3115 2004-02-29 Kevin Ryde <user42@zip.com.au>
3117 * numbers.c (guile_ieee_init): Use C99 INFINITY and NAN when
3118 available. Test HAVE_DINFINITY and HAVE_DQNAN for those globals, in
3119 particular don't assume "defined (__alpha__) && ! defined (linux)"
3120 means OSF. Remove "SCO" code, which was not really SCO specific and
3121 which John W. Eaton advises should be long past being needed.
3123 * posix.c (scm_execl, scm_execlp, scm_execle): Avoid memory leak under
3126 2004-02-24 Kevin Ryde <user42@zip.com.au>
3128 * posix.c (scm_cuserid): Use a private result buffer, for thread safe.
3130 2004-02-22 Kevin Ryde <user42@zip.com.au>
3132 * numbers.c (scm_max, scm_min): For one arg, dispatch to generic for
3133 complex, same as for two args. (Handle only inum, big, real, frac).
3135 2004-02-21 Kevin Ryde <user42@zip.com.au>
3137 * posix.c (scm_crypt): Use new HAVE_CRYPT.
3138 (<crypt.h>): Remove HAVE_LIBCRYPT condition.
3139 Reported by Andreas Voegele.
3141 2004-02-20 Neil Jerram <neil@ossau.uklinux.net>
3143 * list.c (scm_list_n): Add #if SCM_DEBUG_CELL_ACCESSES_P around
3146 * read.c (scm_lreadparen): Removed.
3147 (scm_lreadparen1): Renamed scm_i_lreadparen.
3149 2004-02-20 Han-Wen Nienhuys <hanwen@xs4all.nl>
3151 * list.c (scm_list_n): validate non-immediate arguments;
3152 this will catch forgotten a SCM_UNDEFINED.
3154 2004-02-18 Marius Vollmer <mvo@zagadka.de>
3156 * gc.h (scm_gc_cells_collected): Removed duplicated declaration.
3157 Thanks to Bill Schottstaedt!
3159 * socket.h (scm_gethost): Removed prototype it is already in
3160 "net_db.h". Thanks to Bill Schottstaedt!
3162 2004-02-18 Kevin Ryde <user42@zip.com.au>
3164 * num2integral.i.c (INTEGRAL2BIG): WORDS_BIGENDIAN not right for word
3165 order parameter to mpz_import, in fact with just one word there's no
3166 order to worry about at all.
3168 * numbers.c (scm_num_eq_p): For real==frac, complex==frac, frac==real
3169 and frac==complex, make an exact comparison rather than converting
3170 with fraction2double.
3172 * posix.c, putenv.c, stime.c (environ): Use _NSGetEnviron in Darwin
3173 shared library, since environ is not directly available there.
3175 * script.c (scm_shell_usage): Print to stdout for --help, per GNU
3178 * stime.c (scm_localtime, scm_gmtime, scm_mktime): Provide a default
3179 errno EINVAL in case localtime and gmtime don't set it.
3180 (scm_mktime, scm_strptime): Forcibly use errno EINVAL for our
3181 SCM_SYSERROR, since mktime and strptime generally don't set errno.
3183 2004-02-16 Kevin Ryde <kevin@swox.se>
3185 * gc-malloc.c (scm_done_malloc, scm_done_free): Allow negative sizes,
3186 which were permitted in the past for these.
3188 * num2float.i.c (NUM2FLOAT): Expand isfinite to !xisinf, as per
3189 previous change to numbers.c.
3191 * script.c (scm_shell_usage): Print bug-guile email address, as per
3192 GNU standard. Reported by Han-Wen Nienhuys.
3194 2004-02-13 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3196 * unif.c (scm_make_uve): Removed local variable and simplified
3197 code in order to avoid compiler used uninitialized warnings.
3199 * hashtab.c, hashtab.h (scm_hash_map_to_list): Renamed from
3201 (scm_hash_fold): Use scm_call_3 directly in the call to
3202 scm_internal_hash_fold instead of going via fold_proc (which is
3204 (scm_hash_for_each): Use a trampoline +
3205 scm_internal_hash_for_each_handle.
3206 (scm_internal_hash_for_each_handle, scm_hash_for_each_handle): New
3209 2004-02-12 Kevin Ryde <user42@zip.com.au>
3211 * ports.c (scm_port_line): In docstring, note first line is 0.
3212 (scm_set_port_line_x): In docstring, note first line is 0.
3213 (scm_port_column): In docstring, there's no default to current input
3214 port, and remove shared port-line @defun.
3215 (scm_set_port_column_x): In docstring, there's no default to current
3216 input port, note first column is 0, remove shared set-port-line!
3219 * ramap.c (scm_array_fill_x): For fvect and dvect, use scm_num2dbl to
3220 convert args the same way that array-set! does.
3222 * unif.c (scm_make_uve, scm_array_p): Allow fraction 1/3 as prototype
3224 (scm_array_p): Add missing "break"s in switch, fix llvect test look
3225 for "l" not "s", fix dvect to be false for singp(prot) since such a
3227 (scm_array_prototype): Return 1/3 for dvect, rather than 0.33..33.
3228 (exactly_one_third): New variable.
3229 (scm_init_unif): Initialize it.
3231 2004-02-10 Neil Jerram <neil@ossau.uklinux.net>
3233 * read.c (scm_read_opts): Change `escaped-parens' to
3236 2004-02-08 Neil Jerram <neil@ossau.uklinux.net>
3238 * read.c (scm_read_opts): New opts `elisp-vectors' and
3241 (scm_lreadr): Use scm_lreadparen1 instead of scm_lreadparen. Make
3242 handling of elisp vector syntax dependent on SCM_ENABLE_ELISP and
3243 `elisp-vectors' option instead of SCM_ELISP_READ_EXTENSIONS.
3244 Allow "\(" and "\)" in strings when SCM_ENABLE_ELISP defined and
3245 `escaped-parens' option set.
3246 (scm_read_token): If elisp vector syntax active, disallow [ and ]
3248 (scm_lreadparen): Rewrite as interface to scm_lreadparen1.
3249 (scm_lreadparen1): New.
3251 * read.h: Remove conditionally compiled last arg to
3253 (SCM_ELISP_VECTORS_P, SCM_ESCAPED_PARENS_P): New.
3255 2004-01-23 Han-Wen Nienhuys <hanwen@xs4all.nl>
3257 * eval.c (m_expand_body): remove stray variable new_body.
3259 2004-01-22 Marius Vollmer <mvo@zagadka.de>
3261 * eval.c (m_expand_body): Rewrite the expression in place (by
3262 overwriting FORMS) also when a letrec is constructed, not only
3263 when no definitions are found. Do not return rewritten expression
3264 to emphasize the in-place rewriting. Changed all users.
3266 2004-01-19 Han-Wen Nienhuys <hanwen@xs4all.nl>
3268 * gc.c: add protected_object_count, a number that is dumped from
3271 2004-01-11 Marius Vollmer <mvo@zagadka.de>
3273 * dynwind.h, dynwind.c (scm_frame_unwind,
3274 scm_frame_unwind_handler): Renamed and changed all uses.
3275 (scm_frame_rewind, scm_frame_rewind_handler): Likewise.
3277 2004-01-11 Kevin Ryde <user42@zip.com.au>
3279 * unif.c (scm_bit_count, scm_bit_position, s_scm_bit_set_star_x,
3280 s_scm_bit_count_star, s_scm_bit_invert_x): Clarify docstrings, as per
3281 changes made to scheme-compound.texi.
3283 2004-01-10 Marius Vollmer <mvo@zagadka.de>
3285 * print.c (scm_print_symbol_name): Handle #{`foo}#, #{,foo}#,
3286 #{.}#, and all numeric strings specially. Thanks to Paul Jarc!
3288 * guile-snarf.in: Use mkdir to create a unique temporary directory
3289 that we can safely use. Thanks to Stefan Nordhausen!
3291 2004-01-07 Marius Vollmer <marius.vollmer@uni-dortmund.de>
3293 * dynwind.h, dynwind.c (scm_i_dowinds): Removed 'explicit'
3294 argument since it is always zero now. Changed all callers.
3295 Removed code for handling fluids.
3297 * fluids.c (scm_c_with_fluids): Use frames instead of adding to
3298 the wind chain explicitely. Use scm_c_with_fluid for the common
3299 case of only one fluid.
3300 (scm_with_fluid): New.
3301 (scm_c_with_fluid): Use frames instead of scm_c_with_fluids.
3303 * fluids.h, fluids.c (scm_frame_fluid): New.

3305 (scm_i_swap_fluids, scm_i_swap_fluids_reverse): Removed.
3307 * dynwind.c (scm_frame_end): Do not use scm_i_dowinds. Instead,

3311 scm_begin_frame -> scm_frame_begin,
3312 scm_end_frame -> scm_frame_end,

3316 scm_on_rewind_with_scm -> scm_frame_rewind_with_scm.
3319 * aync.h, async.c: Did the follwing renamings:
3320 scm_with_blocked_asyncs -> scm_frame_block_asyncs,
3321 scm_with_unblocked_asyncs -> scm_frame_unblock_asyncs.
3324 * ports.h, ports.c: Did the follwing renamings:

3333 Reported by Richard Todd.
3335 * threads-plugin.h (SCM_MUTEX_MAXSIZE): Increase to 12*sizeof(long),
3336 for the benefit of powerpc-apple-darwin5.5. Reported by Richard Todd.
3338 * unif.c (scm_aind): Test SCM_CONSP rather than !SCM_NULLP while
3339 traversing the args list, fixes segv if an improper list is given.

3344 * ports.c (swap_ports, scm_with_current_foo_port): Do not allocate
3345 swap_data on stack, use a 'malloc obj'.
3347 * fluids.h, fluids.c (scm_make_initial_fluids, scm_copy_fluids,
3348 scm_swap_fluids, scm_swap_fluids_reverse): Renamed to
3349 scm_i_... since they are internal. Changed all uses.
3351 * dynwind.c (frame_print): Removed, use the default printer.
3352 (WINDER_F_MARK, WINDER_MARK_P, winder_mark): New.
3353 (scm_on_unwind_with_scm, scm_on_rewind_with_scm): New. Use above
3354 to protect SCM values.
3356 * dynwind.h (SCM_F_WIND_EXPLICITELY,
3357 SCM_F_WIND_EXPLICITLY): It's "explicitly" not "explicitely", damn.

3372 scm_begin_frame, scm_end_frame, scm_on_unwind, scm_on_rewind):
3374 (scm_dowinds, scm_i_dowinds): scm_dowinds has been renamed to
3375 scm_i_dowinds and extended to handle frames and to invoke a 'turn'
3376 function when the outermost wind point has been reached. The
3377 latter is used to copy a continuation stack at the right time.
3378 scm_dowinds remains available.
3379 (SCM_GUARDSP, SCM_BEFORE_GUARD, SCM_AFTER_GUARD, SCM_GUARD_DATA,
3380 tc16_guard, guards_print): Removed.
3381 (scm_internal_dynamic_wind): Reimplemented using frames.

3384 part of copy_stack_and_call.
3385 (copy_stack_and_call): Copy the stack after unwinding and before
3387 (scm_dynthrow): Do not call scm_dowinds, this is now done by
3388 copy_stack_and_call.
3390 2004-01-04 Kevin Ryde <user42@zip.com.au>
3392 * numbers.c (scm_less_p): Don't convert frac to float for compares,
3393 can give bad results due to rounding.
3395 * stime.c (scm_current_time, scm_gettimeofday): Add a comment about
3396 setzone/restorezone protection for DOS.

3407 * numbers.c (scm_make_ratio): Check for numerator equal to
3408 SCM_MOST_NEGATIVE_FIXNUM and bignum denominator the negative of that,
3411 * numbers.c (scm_real_part): Return fraction unchanged rather than
3412 converting to flonum.
3414 2003-11-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
3416 * modules.c (module_variable): Fixed (and thus simplified) the
3417 definition of SCM_BOUND_THING_P to reflect the fact that since

3440 * eval.c (s_bad_define): New static identifier.
3442 (m_body): Fixed comment.
3444 (scm_m_define): Don't generate memoized code for definitions that
3445 are not on the top level. As a consequence, no memoized code at
3446 all is generated for definitions any more: Top level definitions
3447 are executed immediately during memoization and internal
3448 definitions are handled separately in m_expand_body.
3450 (scm_unmemocopy, unmemocopy): Removed code for unmemoizing
3451 definitions. Consequently, there is no unmemoizing code any more
3452 that might modify the environment. Thus, the old scm_unmemocopy
3453 is removed and the old unmemocopy is renamed to scm_unmemocopy.
3455 (SCM_CEVAL): The SCM_IM_DEFINE keyword can no longer occur in
3456 memoized code. Call EVALCAR for continuations. Prefer !SCM_NULLP
3457 over SCM_NIMP in places, where the argument is known to be part of

3462 * numbers.c (scm_abs): Allocate a new real only for negatives, as done
3465 * numbers.c (scm_bit_extract): Use mpz functions, rearrange inum case
3466 to share some shifting.
3468 * numbers.c (scm_integer_expt): Don't mpz_init after scm_i_clonebig or
3469 scm_i_mkbig, since they do so already. Don't mpz_clear a bignum SCM,
3472 2003-11-19 Marius Vollmer <mvo@zagadka.de>
3474 * numbers.c (scm_make_ratio): Rewritten to have a simpler
3475 structure. Previously, not all cases with a negative denominator
3478 * numbers.c (mem2decimal_from_point): use scm_divide instead of
3479 scm_divide2real when forming the fractional part. This allows
3480 "#e1.2" to yield 6/5.
3482 * numbers.c (scm_i_fraction_equalp): Do not treat the return value
3483 of scm_equal_p as a C boolean, use SCM_FALSEP. Previously, all
3484 fractions were equal to each other regardless of value. Ooops.

3533 to doubles when calling 'dsubr' functions.
3535 * eq.c (scm_eqv_p, scm_equal_p): Handle fractions.

3539 * gen-scmconfig.c (main): remove public definition of
3540 SCM_SIZEOF___INT64 and SCM_SIZEOF_UNSIGNED___INT64 and add
3541 direct typedef of long_long and ulong_long inside deprecated block
3544 * deprecated.h: move long_long and ulong_long definitions to
3545 gen-scmconfig.c so that we don't need to add SCM_SIZEOF___INT64
3546 and SCM_SIZEOF_UNSIGNED___INT64 to the public namespace.

3559 the "-e" option instead of scm_str2symbol. This allows things
3560 like (@ ...) to be specified for the entry point.

3832 Avoid unnecessary consing when creating the memoized code.
3834 2003-10-12 Kevin Ryde <user42@zip.com.au>
3836 * list.c (scm_append): Track argument number and use in error.
3838 2003-10-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
3840 * eval.c (s_missing_expression, s_bad_variable): New static
3843 (scm_m_define): Use ASSERT_SYNTAX to signal syntax errors. Prefer
3844 R5RS terminology for the naming of variables. Be more specific
3845 about the kind of error that was detected. Make sure file name,
3846 line number etc. are added to all freshly created expressions.
3847 Avoid unnecessary consing when creating the memoized code.
3849 2003-10-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
3851 * eval.c (s_extra_expression, s_misplaced_else_clause,
3852 s_bad_cond_clause, s_missing_recipient): New static identifiers.
3854 (s_extra_case_clause): Removed.
3856 (scm_m_case, scm_m_cond): If a clause appears after an else
3857 clause, report a misplaced else clause.
3859 (scm_m_cond): Use ASSERT_SYNTAX to signal syntax errors. Be more
3860 specific about the kind of error that was detected. Handle bound
3861 'else and '=>. Avoid unnecessary consing when creating the
3864 (scm_m_cond, unmemocopy, SCM_CEVAL): Use SCM_IM_ELSE to memoize
3865 the syntactic keyword 'else and SCM_IM_ARROW to memoize the
3866 syntactic keyword '=>.
3868 2003-10-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
3870 * eval.c (scm_m_case): Allow empty lists of case labels.
3872 2003-10-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
3874 * tags.h (SCM_IM_ELSE, SCM_IM_ARROW): New memoizer codes.
3876 * print.c (scm_isymnames): Add names for the new memoizer codes.
3878 * eval.c (s_missing_clauses, s_bad_case_clause,
3879 s_extra_case_clause, s_bad_case_labels, s_duplicate_case_label,
3880 literal_p): New static identifiers.
3882 (scm_m_case): Use ASSERT_SYNTAX to signal syntax errors. Be more
3883 specific about the kind of error that was detected. Check for
3884 duplicate case labels. Handle bound 'else. Avoid unnecessary
3885 consing when creating the memoized code.
3887 (scm_m_case, unmemocopy, SCM_CEVAL): Use SCM_IM_ELSE to memoize
3888 the syntactic keyword 'else.
3890 2003-10-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
3892 * eval.c (s_bad_expression, syntax_error_key, syntax_error,
3893 ASSERT_SYNTAX, ASSERT_SYNTAX_2): New static identifiers.
3895 (scm_m_and): Use ASSERT_SYNTAX to signal syntax errors. Avoid
3896 unnecessary consing when creating the memoized code.
3898 2003-10-09 Kevin Ryde <user42@zip.com.au>
3900 * numbers.c (scm_inexact_to_exact): Don't depend on what double->long
3901 cast gives for values bigger than a long, or for nan or inf.
3903 2003-10-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
3905 * smob.h (scm_make_smob_type): Made the declaration match the
3908 2003-10-07 Marius Vollmer <mvo@zagadka.de>
3910 * goops.c, objects.h, smob.c, smob.h: Make type names char
3911 const * instead of char *. Thanks to Paul Jarc!
3913 2003-10-02 Kevin Ryde <user42@zip.com.au>
3915 * strports.c (scm_call_with_output_string): scm_get_output_string
3916 rather than scm_strport_to_string, so as to guard against the port
3917 having been closed by the called procedure. Reported by Nic Ferrier.
3919 2003-09-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
3921 * numbers.h (SCM_INEXACTP): Removed uses of SCM_TYP16S.
3923 * tags.h, deprecated.h (SCM_TYP16S): Deprecated and moved from
3924 tags.h to deprecated.h.
3926 2003-09-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
3928 This set of patches introduces a new tc7 code scm_tc7_number for
3929 numbers. Bignums, reals and complex numbers are turned from smobs
3930 into subtypes of scm_tc7_number.
3932 * tags.h (scm_tc7_number): New.
3934 * eq.c (scm_equal_p), eval.c (SCM_CEVAL), evalext.c
3935 (scm_self_evaluating_p), gc-card.c (scm_i_sweep_card), gc-mark.c
3936 (scm_gc_mark_dependencies), goops.c (create_smob_classes), hash.c
3937 (scm_hasher), numbers.c, numbers.h (SCM_NUMP), objects.c
3938 (scm_class_of), print.c (scm_iprin1), smob.c
3939 (scm_smob_prehistory): Don't handle bignums, reals and complex
3940 numbers as subtypes of scm_tc7_smob any more.
3942 * numbers.h, tags.h (scm_tc16_big, scm_tc16_real,
3943 scm_tc16_complex): Moved definitions from tags.h to numbers.h.
3945 2003-09-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
3947 * numbers.c (scm_make_complex), gc-card.c (scm_i_sweep_card): Use
3948 sizeof (scm_t_complex) to determine the memory size of the
3949 malloc'd area for complex numbers.
3951 2003-09-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
3953 * numbers.c (scm_bigequal): Fixed.
3955 2003-09-16 Marius Vollmer <mvo@zagadka.de>
3957 * stime.c (scm_current_time): 'time' does not set errno so don't
3958 use SCM_SYSERROR for reporting errors.
3960 2003-09-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
3962 This set of patches eliminates the dependency between the
3963 implementation of evaluator specific memoization codes and special
3964 constants like #f, '() etc. ('flags'), which are not evaluator
3965 specific. The goal is to remove definitions of evaluator
3966 memoization codes completely from the public interface. This will
3967 make it possible to experiment more freely with optimizations of
3968 guile's internal representation of memoized code.
3970 * objects.c (scm_class_of): Eliminate dependency on SCM_ISYMNUM.
3972 * print.c (iflagnames): New array, holding the printed names of
3973 guile's special constants ('flags').
3975 (scm_isymnames): Now holds only the printed names of the
3978 (scm_iprin1): Separate the handling of memoization codes and
3979 guile's special constants.
3981 * tags.h (scm_tc9_flag, SCM_ITAG9, SCM_MAKE_ITAG9, SCM_ITAG9_DATA,
3984 (scm_tc8_char, scm_tc8_iloc, SCM_BOOL_F, SCM_BOOL_T,
3985 SCM_UNDEFINED, SCM_EOF_VAL, SCM_EOL, SCM_UNSPECIFIED, SCM_UNBOUND,
3986 SCM_ELISP_NIL, SCM_IM_DISPATCH, SCM_IM_SLOT_REF,
3987 SCM_IM_SLOT_SET_X, SCM_IM_DELAY, SCM_IM_FUTURE,
3988 SCM_IM_CALL_WITH_VALUES, SCM_IM_NIL_COND, SCM_IM_BIND): Changed
3991 (SCM_IFLAGP): SCM_IFLAGP now only tests for flags.
3993 (SCM_IFLAGP, SCM_MAKIFLAG, SCM_IFLAGNUM): Generalized to use the
3994 tc9 macros and scm_tc9_flag.
3996 2003-09-15 Marius Vollmer <mvo@zagadka.de>
3998 * posix.c (scm_setgroups): Check that the gid list is not too
3999 long. Thanks to Paul Jarc!
4001 2003-09-14 Dirk Herrmann <D.Herrmann@tu-bs.de>
4003 * tags.h: Reduced the number of short instructions from 14 to 13.
4004 The typecode of the former 14th short instruction is now used to
4005 represent long instructions. Changed some comments to reflect
4008 (SCM_MAKISYM): ISYMs get a new tc7 code, namely the one that was
4009 previously used by SCM_IM_DEFINE.
4011 (SCM_IM_DEFINE): Turned into a long instruction.
4013 * eval.c (unmemocopy, SCM_CEVAL): Treat SCM_IM_DEFINE as a long
4016 * eval.c (SCM_CEVAL): Since characters and iflags have now a tc7
4017 code that is separate from all instructions, one level of dispatch
4018 for long instructions can be eliminated.
4020 * print.c (scm_isymnames): Removed some commented code.
4022 2003-09-12 Marius Vollmer <mvo@zagadka.de>
4024 * __scm.h (SCM_FENCE): Use __memory_barrier with the Intel
4027 * hashtab.h (scm_tc16_hashtable): Added "extern" declaration.
4029 * modules.c (scm_module_reverse_lookup): Check that the obarray
4030 really is a hashtable and do nothing if not.
4032 * inline.h: Use "extern inline" only with GCC. Use "static
4035 2003-09-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
4037 * numbers.h (SCM_INEXACTP, SCM_REALP, SCM_COMPLEXP): Removed uses
4038 of SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP.
4040 * numbers.h, deprecated.h (SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP,
4041 SCM_SLOPPY_COMPLEXP): Deprecated and moved from numbers.h to
4044 2003-09-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
4046 * eq.c (scm_eqv_p, scm_equal_p): Removed uses of
4047 SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP.
4049 * eq.c (scm_eqv_p, scm_equal_p): Reordered comparisons from
4050 0.0==some_expression to some_expression==0.0. The latter is
4051 better readable. The former is preferred by some people, since it
4052 leads to a compiler error when confusing == with =. However, when
4053 using gcc, a warning will be issued if in an if-statement an
4054 assigment appears. Since many Guile developers are using gcc,
4055 such errors will not remain unnoticed anyway. We can therefore
4056 focus on better readability.
4058 2003-09-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
4060 * tags.h: Added description of Guile's type system. Removed some
4061 old and misleading comments.
4063 2003-09-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
4065 * unit.c (scm_cvref): Eliminate unnecessary uses of SCM_NIMP,
4066 SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP.
4068 2003-09-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
4070 * numbers.h (SCM_MAKINUM): Define in terms of scm_tc2_int.
4072 (SCM_INEXACTP, SCM_REALP, SCM_COMPLEXP): Define in terms of the
4073 respective SLOPPY macro.
4075 2003-09-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
4077 * eq.c (scm_equal_p): Use SCM_TYP7 to check if an object is of
4078 type string, not SCM_TYP7S.
4080 2003-09-03 Kevin Ryde <user42@zip.com.au>
4082 * numbers.c (scm_lognot): Correction to docstring, ones-complement not
4085 * stime.c (scm_strptime): Add comment about glibc strptime %s and
4086 current timezone requiring SCM_DEFER_INTS.
4088 2003-08-30 Neil Jerram <neil@ossau.uklinux.net>
4090 * script.c (scm_compile_shell_switches): Make -s switch optional
4091 if file to be loaded does not begin with a `-'. (Thanks to Aaron
4092 VanDevender for the patch!)
4094 2003-08-30 Kevin Ryde <user42@zip.com.au>
4096 * numbers.c (scm_lognot): Rewrite using ~ and mpz_com, for directness
4097 and to have non-integer types rejected as per other logical funcs.
4099 2003-08-28 Kevin Ryde <user42@zip.com.au>
4101 * gc.h (scm_remember_upto_here_1): Revise comments on the asm form.
4103 2003-08-23 Kevin Ryde <user42@zip.com.au>
4105 * simpos.c (scm_system): Remove SCM_DEFER_INTS, system() should be
4106 thread safe, and could take a long time too.
4108 2003-08-22 Kevin Ryde <user42@zip.com.au>
4110 * numbers.c (scm_difference): Correction to bignum - negative inum.
4112 2003-08-14 Kevin Ryde <user42@zip.com.au>
4114 * gc.h (scm_remember_upto_here_1, scm_remember_upto_here_2)
4115 [__GNUC__]: Use volatile asm macros rather than a function call.
4116 * gc.c (scm_remember_upto_here_1, scm_remember_upto_here_2): Undefine
4117 macros while defining functions.
4119 * simpos.c (getenv): Use <stdlib.h> for prototype.
4120 (scm_system): In docstring, refer to status:exit-val rather than
4123 2003-08-09 Kevin Ryde <user42@zip.com.au>
4125 * srcprop.c (scm_source_properties): Return plist from hash if it's a
4126 list set by source-properties! rather than an SRCPROPS object,
4128 2003-07-29 Kevin Ryde <user42@zip.com.au>
4130 * properties.c (scm_primitive_property_ref): In docstring, note
4131 parameters to not-found-proc, use hyphens rather than underscores for
4132 that parameter name.
4133 (scm_primitive_property_set_x): In docstring, VAL is the value
4136 2003-07-27 Marius Vollmer <mvo@zagadka.de>
4138 * print.c (scm_print_symbol_name): handle more weird characters by
4139 escaping the symbol name properly. Thanks to Paul Jarc!
4141 * posix.h (scm_setgroups): New prototype.
4142 * posix.c (scm_setgroups): New. Thanks to Paul Jarc!
4143 (scm_getgroups): Handle groups ids that don't fit into a fixnum.
4144 Don't use SCM_WRITABLE_VELTS.
4146 * gc.h (SCM_GC_SET_CELL_BVEC): New.
4147 * gc-card.c (scm_i_init_card_freelist): Use it. Thanks to
4150 * __scm.h (SCM_C_INLINE_KEYWORD): New.
4151 * numbers.c: Use it in place of SCM_C_INLINE so that the code
4152 compiles when SCM_C_INLINE is undefined.
4154 2003-07-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
4156 * __scm.h: Reformulated the architecture and compiler properties
4157 in terms of properties of scm_t_bits and SCM variables rather than
4158 in terms of c standard types. This is since it is not known which
4159 of the standard types scm_t_bits and SCM variables will be defined
4162 2003-07-24 Kevin Ryde <user42@zip.com.au>
4164 * numbers.c (scm_angle): Use scm_flo0 for non-negative inum, bignum
4167 2003-07-18 Kevin Ryde <user42@zip.com.au>
4169 * numbers.c (scm_product): In complex * bignum, correction to
4170 REAL/IMAG fetch, x is the complex, not y.
4172 2003-07-13 Mikael Djurfeldt <djurfeldt@nada.kth.se>
4174 * numbers.c (scm_odd_p, scm_even_p): Bugfix: Treat result of
4175 scm_inf_p test as Scheme values.
4176 (scm_sum): Bugfix: Normalize bignum created from a negative bignum
4177 and a positive inum.
4178 Use GNU indentation style.
4180 2003-07-12 Dirk Herrmann <D.Herrmann@tu-bs.de>
4182 * values.c (scm_values): Build lists of length 1 by using
4183 scm_list_1 instead of using scm_cons.
4185 2003-07-10 Kevin Ryde <user42@zip.com.au>
4187 * deprecation.c (scm_c_issue_deprecation_warning_fmt): Add va_end.
4188 * list.c (scm_list_n): Ditto.
4190 * gc-malloc.c (scm_gc_realloc): Define "ptr" at start of function.
4192 2003-07-08 Matthias Koeppe <mkoeppe@merkur.math.uni-magdeburg.de>
4194 * tags.h (scm_t_bits, scm_t_signed_bits, etc): Avoid solaris empty
4195 defines of INTPTR_MAX and UINTPTR_MAX, combine conditionals for
4196 scm_t_bits and scm_t_signed_bits to avoid any chance of one and not
4197 the other using intptr_t.
4199 2003-07-08 Kevin Ryde <user42@zip.com.au>
4201 * numbers.c (scm_make_polar): Use sincos, when available.
4202 (scm_magnitude): Use hypot.
4204 * ports.c (scm_char_ready_p, scm_peek_char): In docstrings, don't use
4205 @footnote since it doesn't go through to guile-procedures.txt.
4207 * threads.c (scm_call_with_new_thread): In docstring, use "( )"
4208 outside @var to quieten makeinfo, and use @code.
4210 2003-07-06 Han-Wen Nienhuys <hanwen@cs.uu.nl>
4212 * gc-malloc.c (decrease_mtrigger): new function
4213 (increase_mtrigger): new function, separate debug registering and
4214 mtrigger administration.
4215 (scm_gc_realloc): bugfix: do mtrigger administration before the
4216 actual realloc, for the realloc might invalidate a GC-d segment of
4217 memory. Thanks to Sam Hocevar for pointing this out.
4218 (scm_gc_realloc): use scm_malloc_reregister instead of
4219 unregistering and registering in sequence.
4221 2003-07-03 Han-Wen Nienhuys <hanwen@cs.uu.nl>
4223 * __scm.h (SCM_ASSERT): change "else" expansion to "do { } while (0)"
4225 2003-07-02 Han-Wen Nienhuys <hanwen@cs.uu.nl>
4227 * __scm.h (SCM_ASRTGO): add "else" to macro expansions with if
4230 2003-06-29 Marius Vollmer <mvo@zagadka.de>
4232 * deprecated.h (SCM_OPDIRP, scm_fport, scm_option, scm_srcprops,
4233 scm_srcprops_chunk, scm_info_frame, scm_stack, scm_array,
4234 scm_array_dim, SCM_ARRAY_CONTIGUOUS, SCM_FUNC_NAME, SCM_WTA,
4235 RETURN_SCM_WTA, SCM_VALIDATE_NUMBER_COPY,
4236 SCM_VALIDATE_NUMBER_DEF_COPY, SCM_VALIDATE_OPDIR): Re-added from
4237 the release_1_6 branch.
4239 2003-06-25 Stefan Jahn <stefan@lkcc.org>
4241 * continuations.c: Redeclaration of getcontext() via the
4242 __asm__ ("getcontext") directive.
4244 * continuations.h: Include <ucontext.h> instead of
4247 2003-06-21 Kevin Ryde <user42@zip.com.au>
4249 * numbers.c (_GNU_SOURCE): #define, to get C99 things.
4250 (scm_asinh, scm_acosh, scm_atanh, scm_truncate, $asinh, $acosh,
4251 $atanh, truncate): Use C library asinh, acosh, atanh and trunc, when
4253 (scm_inexact_to_exact): Expand isfinite to its definition !xisinf.
4254 (isfinite): Remove, conflicts with C99 isfinite().

4261 scm_unintern_symbol, scm_symbol_binding, scm_symbol_interned_p,
4262 scm_symbol_bound_p, scm_symbol_set_x, scm_gentemp): Re-added from
4263 the release_1_6 branch.
4265 2003-06-14 Stefan Jahn <stefan@lkcc.org>
4267 * threads.h: Redefined scm_getspecific() and scm_setspecific()
4268 to be functions instead of macros.
4270 * threads.c: Conditionalized inclusion of <sys/time.h> and
4272 (scm_getspecific, scm_setspecific): Made these two function
4273 real part of the API.
4275 * posix.c (s_scm_putenv): Added some code to make a
4276 (putenv "FOO="), i.e. setting an empty string, work also on
4277 Win32 systems. Thanks to Kevin Ryde for the proposal.
4279 2003-06-12 Kevin Ryde <user42@zip.com.au>
4281 * posix.c (scm_putenv): Free temporary ptr in mingw unset. Add
4282 freebsd to comment about need to use unsetenv.
4284 2003-06-02 Marius Vollmer <mvo@zagadka.de>
4286 * ports.c (scm_peek_char): Safe the column of the port around the
4287 getc/ungetc calls. Thanks to Dr. Peter Ivanyi!
4289 2003-06-07 Kevin Ryde <user42@zip.com.au>
4291 * tags.h: Use inttypes.h and stdint.h when available, for INTPTR_MAX
4292 and friends required by scm_t_bits setups.
4294 2003-06-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
4296 * tags.h (scm_tc2_int): Added.
4298 * tags.h (scm_tc3_int_1, scm_tc3_int_2): Expressed in terms of
4301 * tags.h (scm_tcs_cons_imcar, scm_tcs_cons_nimcar, scm_tcs_struct,
4302 scm_tcs_closures): Hard coded values replaced by symbolic ones.
4304 2003-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
4306 * eval.c: Partially undid my patch from 2003-05-31. This patch
4307 caused the segfault referenced in the previous changelog entry.
4309 2003-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
4311 * tags.h: Fixed comment about the immediate type code layout.
4313 * eval.c: Fixed handling of non-special instructions. Without
4314 this patch, guile will segfault on (#\0) and similar instructions.
4316 2003-06-05 Kevin Ryde <user42@zip.com.au>
4318 * numbers.c (scm_max, scm_min): For inum, bignum and real, if other
4319 operand is NaN, then return NaN. Also avoid passing NaN to mpz_cmp_d.
4321 * read.c (scm_input_error): Pass arg list parameter to scm_error_scm,
4322 rather than SCM_EOL. Needed by "Unknown # object" case in scm_lreadr.
4324 2003-06-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
4326 * __scm.h, gc-card.c (SCM_DEBUG_DEBUGGER_SUPPORT,
4327 SCM_DEBUG_DEBUGGING_SUPPORT): Renamed macro
4328 SCM_DEBUG_DEBUGGER_SUPPORT to SCM_DEBUG_DEBUGGING_SUPPORT and
4329 generalized it to apply not only to C level functions but also to
4330 scheme level functions.
4332 * debug.c, debug.h, eval.c (make-iloc, scm_make_iloc, iloc?,
4333 scm_iloc_p, dbg-make-iloc, scm_dbg_make_iloc, dbg-iloc?,
4334 scm_dbg_iloc_p): Moved functions scm_make_iloc, scm_iloc_p to
4335 eval.c, made them available under SCM_DEBUG_DEBUGGING_SUPPORT == 1
4336 only and renamed them to scm_dbg_make_iloc, scm_dbg_iloc_p,
4339 * deprecated.h, eval.c, eval.h (SCM_ILOC00, SCM_IDINC,
4340 SCM_IDSTMSK): Deprecated. The macro definitions are moved from
4341 eval.h into eval.c and a copy is placed into deprecated.h.
4343 * eval.c, eval.h (SCM_MAKE_ILOC): Removed from eval.h and placed
4344 into eval.c. This definition was not part of the API in any
4345 officially released version of guile and thus does not need to go
4346 through a phase of deprecation.
4348 2003-06-02 Dirk Herrmann <D.Herrmann@tu-bs.de>
4350 * deprecated.c, deprecated.h, eval.c, eval.h (scm_s_expression,
4351 scm_s_test, scm_s_body, scm_s_bindings, scm_s_variable,
4352 scm_s_clauses, scm_s_formals): Deprecated. In eval.c the
4353 definitions are make static and renamed from scm_s_xxx to s_xxx.
4354 In deprecated.c the original definitions are copied.
4356 * deprecated.h, eval.c, eval (SCM_EVALIM2, SCM_EVALIM, SCM_XEVAL,
4357 SCM_XEVALCAR): Deprecated. The macro definitions are moved from
4358 eval.h into eval.c and a copy (slightly modified to work in user
4359 code) is placed into deprecated.h.
4361 * eval.c: Use the local static s_xxx definitions instead of the
4362 scm_s_xxx definitions throughout.
4364 2003-06-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
4366 This set of patches separates the representation of the cxr family
4367 of functions (car, cdr etc.) from the dsubr family of functions
4368 (i. e. functions that take a double precision floating point
4369 argument). Further, the algorithm for handling the cxr function

4394 2003-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
4396 * eval.c (SCM_CEVAL): Improved readability of call-with-values
4397 execution. Generalize apply_closure to apply_proc and use that
4398 for call-with-values.
4400 2003-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>

4511 a compilation error if error-on-warning is enabled).
4513 2003-05-17 Marius Vollmer <mvo@zagadka.de>
4515 * c-tokenize.lex: Gobble up complete lines after a '#'. This
4516 removes preprocessor directives from the snarfage that might
4517 otherwise confuse us. These directives appear when compiling with

4562 * numbers.c (scm_integer_length): On negative bignums, adjust
4563 mpz_sizeinbase to account for it looking at absolute value where we
4564 want ones-complement.
4566 * numbers.c (scm_gcd): In bignum/inum, don't pass yy==0 to mpz_gcd_ui
4567 since we're only using the ulong return value, and x might not fit.
4569 2003-05-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
4571 * eval.c, eval.h, read.c, read.h (scm_sym_dot): Moved from eval to

4587 The purpose of this patch is to make guile's internal memoizers
4588 distinguishable from memoizing macros created on the scheme level
4589 or from user provided primitive memoizing macros. The reason is,
4590 that the internal memoizers are the only ones that are allowed to
4591 transform their scheme input into memoizer byte code, while all
4592 other memoizing macros may only transform scheme code into new
4595 To achieve this, a new macro type 'builtin-macro!' is introduced.
4596 Currently, 'builtin-macro!'s are handled as memoizing macros, but
4597 this will change when the memoizer and executor are separated.
4599 * macros.[ch] (scm_i_makbimacro): New.
4601 * macros.h (SCM_BUILTIN_MACRO_P): New.
4603 * macros.c (macro_print, scm_macro_type): Support builtin-macro!s.
4605 * eval.c, goops.c: All of guile's primitive memoizing macros are
4606 primitive builtin-macros now.
4608 * eval.c (scm_macroexp, SCM_CEVAL): Make sure the primitive
4609 builtin-macros are handled equally to memoizing macros.
4611 2003-05-04 Marius Vollmer <mvo@zagadka.de>
4613 * throw.c (scm_ithrow): Remove "asm volatile" hack. It used to
4614 work around a bug in GCC 2.95.2 but is now a bug in itself.
4616 2003-05-02 Marius Vollmer <mvo@zagadka.de>
4618 * deprecated.h (scm_rstate, scm_rng, SCM_SLOPPY_CONSP,

4641 macro was introduced in anticipation of GOOPS method compilation
4644 * goops.c: Removed binding of @dispatch.
4646 2003-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
4648 * eval.c, goops.c (@dispatch, @slot-ref, @slot-set!): Move the
4649 instructions that bind the macros on the scheme level back to
4650 goops.c in order to make sure again that the bindings go into the
4651 (oop goops) module and are not visible from the outside.
4653 2003-04-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
4655 * eval.c: Non functional change: Separated R5RS and non-R5RS
4656 macros into different sections of the file and ordered the
4657 memoizers alphabetically.

4665 * eval.c (scm_i_call_closure_0, call_closure_1, call_closure_2):
4666 Partially reverted patch from 2003-04-23 in oder to find a better

4672 scm_m_atslot_set_x, scm_m_atdispatch): Move the declarations and
4673 definitions of the special goops memoizers from goops.[ch] to
4674 eval.[ch]. Hmm... it seems that scm_m_atdispatch is not used

4698 This set of patches contains no functional changes, only debatable
4699 minor stylistic ones. Still, in order to prepare a patch between
4700 my local copy and the CVS version, I decided to submit the changes
4701 below. Then, the patch will hopefully only contain relevant
4704 * eval.c (iqq): Added const specifier.
4706 * eval.c (scm_trampoline_0, scm_trampoline_1, scm_trampoline_2):
4707 Use NULL instead of 0 to indicate that a pointer is returned.

4717 SCM_EXIT_FRAME_HDLR): Use SCM_PACK to convert data to a SCM value
4718 rather than casting to SCM.
4720 2003-04-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
4722 * sort.c, pairs.h: Removed unnecessary includes.
4724 2003-04-23 Dirk Herrmann <D.Herrmann@tu-bs.de>

4738 cmp_fun_t): Removed.
4740 (compare_function): Added.
4742 * sort.c (quicksort, SWAP, stack_node): Replaced pointer
4743 arithmetics with index arithmetics. Changed quicksort to work on
4744 an array of SCM values instead of an array of characters. Avoid
4745 bytewise copying of SCM elements. Avoid allocating memory on the
4746 stack with alloca. Fixed some comments.
4748 2003-04-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
4750 * eval.c (EXTEND_ENV): Eliminated.

4760 compiling with SCM_DEBUG==1 by moving definition behind prototype.
4762 * gc.card.c (scm_dbg_t_list_cell, scm_dbg_t_double_cell,

4765 scm_gc_marked_p, scm_gc_get_card, scm_gc_get_bvec): Fixed
4766 functions such that they check if the object is a non-immediate.
4767 Further, renamed identifiers to use the scm_dbg_ prefix and made
4768 their inclusion into the lib dependent of the
4769 SCM_DEBUG_DEBUGGER_SUPPORT compile time option.

4778 * list.c (scm_ilength, scm_last_pair), unif.c (l2ra): Prefer
4779 !SCM_CONSP over SCM_NCONSP. Now, guile itself does not include
4780 any calls to SCM_NCONSP any more.
4782 * unif.c (l2ra): Eliminate redundant check.
4784 2003-04-21 Dirk Herrmann <D.Herrmann@tu-bs.de>

4787 scm_array_map_x), unif.c (l2ra): Prefer !SCM_NULLP over
4788 SCM_NNULLP. Now, guile itself does not include any calls to
4789 SCM_NNULLP any more.
4791 2003-04-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
4793 * eval.c (unmemocopy, SCM_APPLY, scm_map, scm_for_each,
4794 scm_copy_tree): Place assignment expressions which are part of
4795 other expressions into an expression of their own.
4797 2003-04-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
4799 * goops.c (TEST_CHANGE_CLASS, scm_sys_initialize_object): Don't
4800 compare SCM values with !=.

4804 * eval.c, eval.h, evalext.c, evalext.h (scm_sym_setter,
4805 scm_m_generalized_set_x, scm_init_evalext): Move the declaration
4806 and definition of the memoizer for the generalized set! macro from

4808 define the macro object.
4810 * eval.c, eval.h (s_set_x, scm_s_set_x, scm_m_set_x,
4811 scm_m_generalized_set_x): Since now scm_s_set_x is only used in
4812 eval.c, it is made static and renamed to s_set_x.
4814 * evalext.c (scm_defined_p, scm_m_undefine): Prefer !SCM_<foo>
4817 2003-04-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
4819 * eval.c, root.h (scm_undefineds, SCM_NUM_PROTECTS, undefineds,
4820 scm_init_eval): Made scm_undefineds static in eval.c, renamed it
4821 to undefineds and registered the object as a permanent object.
4823 * eval.c, eval.h (scm_f_apply, scm_init_eval): Made scm_f_apply
4824 static in eval.c, renamed it to f_apply and registered the object
4825 as a permanent object.
4827 2003-04-20 Dirk Herrmann <D.Herrmann@tu-bs.de>

5425 (HAVE_LONG_LONGS): definition removed (see NEWS).
5426 (HAVE_LONG_LONG): definition removed (see NEWS).
5427 (HAVE_PTRDIFF_T): definition removed (see NEWS).
5429 * Makefile.am: scmconfig.h is now generated by building and
5430 running gen-scmconfig.h and capturing its output. gen-scmconfig
5431 uses config.h and the configure.in generated gen-scmconfig.h to
5432 decide what to output. See gen-scmconfig.c for details.
5433 (noinst_PROGRAMS): add gen-scmconfig.
5434 (gen_scmconfig_SOURCES): new variable.
5435 (gen-scmconfig.$(OBJEXT)): new target - be careful to handle
5436 cross-compiling right.
5437 (scmconfig.h): build scmconfig.h from gen-scmconfig's output.
5438 (BUILT_SOURCES): add scmconfig.h.
5440 2003-03-19 Marius Vollmer <mvo@zagadka.de>
5442 * gc_os_dep.c: Added defines for sparc-unknown-netbsdelf1.5 from
5443 Adrian Bunk. Thanks!
5445 2003-03-19 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5447 * goops.c (make_class_from_template): New fourth arg:
5449 (scm_class_extended_generic_with_setter, scm_class_self): Fixed
5452 * smob.c (scm_set_smob_apply): Call scm_i_inherit_applicable.
5454 * goops.c, objects.c, objects.h (scm_make_extended_class): New
5455 second arg: applicablep.
5456 (scm_i_inherit_applicable): New function.
5458 * goops.c, goops.h (scm_class_applicable,
5459 scm_class_extended_accessor): New classes.
5461 2003-03-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
5463 * procs.c (scm_procedure_documentation): Removed redundant
5464 SCM_NIMP test and replaced other calls to SCM_IMP by more explicit
5467 2003-03-11 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5469 * list.c, list.h (scm_filter, scm_filter_x): New functions.
5471 * modules.c (scm_module_import_interface): New function.
5473 * goops.c, goops.h (scm_class_accessor_method): Renamed from

5485 * snarf.h (SCM_PRIMITIVE_GENERIC, SCM_PRIMITIVE_GENERIC_1): New
5488 * numbers.c (scm_abs): Use SCM_PRIMITIVE_GENERIC. (This is only a
5489 testing example. All uses of SCM_GPROC should be converted.)
5491 * procprop.c (scm_stand_in_scm_proc): Use scm_assq instead of
5494 * eq.c (scm_equal_p): Turned into a primitive generic.
5496 2003-02-27 Rob Browning <rlb@defaultvalue.org>
5498 * Makefile.am (scmconfig.h): new target -- generate file from
5500 (modinclude_HEADERS): remove version.h.
5501 (nodist_modinclude_HEADERS): add version.h.
5503 2003-02-24 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5505 This fixes a serious GC bug, introduced during the latest
5506 reorganization of the GC, which disabled freeing of structs and
5509 * struct.c (scm_struct_prehistory): Init scm_i_structs_to_free to
5511 (scm_struct_prehistory): Move scm_free_structs to
5512 scm_before_mark_c_hook.
5514 * gc-card.c (sweep_card): Check that we haven't swept structs on
5515 this card before. That can happen if scm_i_sweep_all_segments has
5516 been called from some other place than scm_igc.
5518 2003-02-19 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5520 * environments.c (DEFAULT_OBARRAY_SIZE): Changed from 137 to 31
5521 (since hash tables now adapt their size).
5523 * modules.c (scm_modules_prehistory): Changed from 2001 to 1533
5524 (current number of prehistory bindings; hashtable code will select
5525 a prime which is greater than this value).
5527 * symbols.c (scm_symbols_prehistory): Changed from 1009 to 2139
5528 (current number of initial symbols).
5530 * properties.c (scm_init_properties): Don't specify size of
5531 scm_properties_whash.
5533 * objprop.c (scm_init_objprop): Don't specify size of
5536 * keywords.c (scm_init_keywords): Don't specify a hash table size.
5538 * hooks.c (scm_c_hook_add): Fixed bug in append mode.
5540 The following changes introduce the use of resizable hash tables
5541 throughout Guile. It also renames the old *-hash-table* functions
5542 to *-alist-vector* and places them, together with the rest of the
5543 weak vector support, in the module (ice-9 weak-vector). We should
5544 probably introduce a new, better, API for weak references, for
5545 example "weak pairs" a la MIT-Scheme. (In Chez scheme, they even
5546 look like and are used like ordinary pairs.)
5548 * environments.c (obarray_enter, obarray_retrieve, obarray_remove,
5549 leaf_environment_fold, obarray_remove_all): Use hashtable
5552 * gc.c (scm_init_storage): Moved hook initialization to
5553 scm_storage_prehistory.
5554 (scm_storage_prehistory): New function.

5556 scm_after_sweep_c_hook.
5558 * gc-mark.c (scm_mark_all): Use hashtable accessors.
5559 (scm_gc_mark_dependencies): Use SCM_WVECT_WEAK_KEY_P and
5560 SCM_WVECT_WEAK_VALUE_P.
5562 * hashtab.c, hashtab.h (scm_hash_for_each, scm_hash_map): New
5564 (scm_vector_to_hash_table, scm_c_make_resizing_hash_table):
5566 (scm_make_weak_key_hash_table, scm_make_weak_value_hash_table,
5567 scm_make_doubly_weak_hash_table): Moved here from weaks.c.
5569 * init.c (scm_init_guile_1): Removed call to scm_init_weaks; Added
5570 calls to scm_storage_prehistory and scm_hashtab_prehistory.
5572 * modules.c (module-reverse-lookup): Use hashtable accessors.
5574 * symbols.c, symbols.h (scm_i_hash_symbol): New function.
5576 * weaks.c, weaks.h (scm_make_weak_key_alist_vector,
5577 scm_make_weak_value_alist_vector,
5578 scm_make_doubly_weak_alist_vector): New functions.
5580 * weaks.c (scm_init_weaks_builtins): New function.
5582 * weaks.h (SCM_WVECTF_WEAK_KEY, SCM_WVECTF_WEAK_VALUE,
5583 SCM_WVECTF_NOSCAN, SCM_WVECT_WEAK_KEY_P, SCM_WVECT_WEAK_VALUE_P,
5584 SCM_WVECT_NOSCAN_P): New macros.
5586 * weaks.c (scm_scan_weak_vectors): Use SCM_WVECT_WEAK_KEY_P
5587 and SCM_WVECT_WEAK_VALUE_P.
5589 * weaks.c, weaks.h (scm_i_allocate_weak_vector): Renamed from
5590 allocate_weak_vector and exported.
5592 2003-02-13 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5594 * hashtab.c: Undid thread safety. (We decided that it's better to
5595 let the user explicitly protect the tables (or not) according what
5596 is suitable for the application.)
5598 2003-02-12 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5600 * hashtab.c (scm_hash_fn_remove_x, scm_internal_hash_fold): Made
5601 thread safe and handle resizing tables.
5602 (scm_ihashx, scm_sloppy_assx, scm_delx_x): Removed
5603 SCM_DEFER/ALLOW_INTS.
5605 2003-02-11 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5607 * hashtab.c (scm_vector_to_hash_table,
5608 scm_c_make_resizing_hash_table, scm_make_hash_table): New
5610 (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x): Made thread
5611 safe and handle resizing tables.
5613 * weaks.c (scm_make_weak_key_hash_table,
5614 scm_make_weak_value_hash_table, scm_make_doubly_weak_hash_table):
5615 Size argument made optional. Return resizable table if not
5618 2003-02-10 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5620 * eval.c (scm_trampoline_0, scm_trampoline_1, scm_trampoline_2):
5621 Fixed formals tests for closures. (Thanks to Kevin Ryde.)
5623 2003-02-05 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5625 * debug.c (scm_procedure_source): Handle all objects for which
5626 procedure? is #t. (Thanks to Bill Schottstaedt.)
5628 2003-01-23 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5630 * futures.c (mark_futures): Don't need to mark data of recycled
5632 (scan_futures, cleanup_undead): Be smarter about marking
5633 futures---avoid unnecessary passes through future lists.
5635 * futures.h, futures.c: New files; Introduced recycling of
5636 futures. For fine-grained threading this lifts performance to
5637 another level. We can now use parallelization in inner loops of
5638 Guile programs without impossible overhead.
5640 * threads.h, threads.c: Moved futures to their own file.
5642 * Makefile.am (libguile_la_SOURCES): Added futures.c.

5666 2003-01-22 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5668 * threads.c (create_thread): Don't unwind dynwind chain of parent
5669 thread before creation. Just start the new thread with an empty

5679 waiting also for simple condition variables.
5681 * goops.c (TEST_CHANGE_CLASS): Use scm_change_object_class instead

5686 * ramap.c (scm_ramapc): Typo in error message.
5688 2003-01-08 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5690 * goops.c (scm_sys_prep_layout_x): Bugfix: Only create layout for
5691 slots with instance allocation.
5693 * goops.c, goops.h (scm_class_extended_generic_with_setter): New
5695 (scm_compute_applicable_methods): Use scm_generic_function_methods.

5700 2002-12-29 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5702 * eval.c (unmemocopy): Bugfix: scm_sym_delay --> scm_sym_future.
5703 Thanks to Neil for pointing this out!
5705 2002-12-29 Neil Jerram <neil@ossau.uklinux.net>
5707 * lang.h: Remove declarations matching definitions removed from
5708 lang.c (just below).

5713 scm_m_while, scm_nil_eq): Remove definitions that were superfluous
5714 and already commented out.
5716 * read.h (scm_lreadparen), read.c (scm_lreadr, scm_read_token,
5717 scm_lreadparen): Support reading vectors with Elisp syntax if
5718 SCM_ELISP_READ_EXTENSIONS is defined. (SCM_ELISP_READ_EXTENSIONS
5719 is not currently defined, and there isn't even a configure switch
5722 2002-12-26 Marius Vollmer <mvo@zagadka.ping.de>
5724 * Makefile.am (c-tokenize.o): Refer to source via $< so that vpath
5726 (EXTRA_DIST): Added version.h.in.
5728 2002-12-21 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5730 This change makes it possible for one thread to do lazy sweeping
5731 while other threads are running. Now only the mark phase need to
5732 have all threads asleep. We should look further into this issue.
5733 Presently, I've put the locking of scm_i_sweep_mutex at
5734 "conservative" places due to my current lack of knowledge about
5735 the garbage collector. Please feel free to restrict these regions
5736 further to allow for maximal parallelism!
5738 * gc.c, gc.h (scm_i_sweep_mutex): New mutex.

5745 the single-thread section (which now only contains the mark
5747 (scm_gc): Don't lock sweeo mutex here since scm_igc locks it;
5748 Removed SCM_DEFER/ALLOW_INTS. Simply call scm_igc directly.
5750 * threads.c (gc_section_mutex): Removed.
5752 2002-12-19 Mikael Djurfeldt <mdj@kvast.blakulla.net>
5754 * threads.c (create_thread): Clear parent field in root state in
5755 order not to unnecessarily remember dead threads.

5779 * threads.c (really_launch): Detach before unlocking
5780 thread_admin_mutex in order not to risk being joined.
5781 (scm_i_thread_put_to_sleep, scm_i_thread_wake_up): Keep
5782 thread_admin_mutex locked during GC.
5784 * pthread-threads.c, pthread-threads.h: Improvements to debugging
5787 2002-12-16 Mikael Djurfeldt <mdj@kvast.blakulla.net>
5789 * pthread-threads.c, pthread-threads.h (SCM_DEBUG_THREADS): Added
5790 support for debugging mutex operations.

5793 (thread_print): Print thread number as well as address of thread
5795 (scm_join_thread): Bugfix.

5800 unintended destruction).
5801 (scm_threads_prehistory): Initialize heap_mutex of fake thread.
5803 * pthread-threads.c, pthread-threads.h, threads.c: Fixes to
5804 pthread "native" recursive mutex support.

5809 Simply lock a thread C API recursive mutex.
5810 (SCM_NONREC_CRITICAL_SECTION_START,
5811 SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START,
5812 SCM_REC_CRITICAL_SECTION_END): Removed.
5814 * eval.c: Replaced SOURCE_SECTION_START / SOURCE_SECTION_END with
5815 direct calls to scm_rec_mutex_lock / unlock around the three calls
5816 to scm_m_expand_body.
5818 * eval.c, eval.h (promise_free): New function.
5819 (scm_force): Rewritten; Now thread-safe; Removed
5820 SCM_DEFER/ALLOW_INTS.
5822 * pthread-threads.h: Added partially implemented plugin interface
5823 for recursive mutexes. These are, for now, only intended to be
5824 used internally within the Guile implementation.
5826 * pthread-threads.c: New file.
5828 * threads.c: Conditionally #include "pthread-threads.c".
5830 * eval.c, eval.h (scm_makprom, scm_force): Rewritten to be
5833 * snarf.h (SCM_MUTEX, SCM_GLOBAL_MUTEX, SCM_REC_MUTEX,
5834 SCM_GLOBAL_REC_MUTEX): New macros.

5860 * threads.c (create_thread): Remember root object until the handle
5861 of the new thread is on all_threads list.
5863 * root.c (scm_make_root): Moved copying of fluids until after
5864 creation of root handle so that the fluids are GC protected. Also
5865 removed the critical section.
5867 2002-12-10 Mikael Djurfeldt <mdj@kvast.blakulla.net>
5869 * gc-malloc.c, gc.h (scm_gc_malloc_prehistory): New function.

5877 through scm_malloc.)
5879 * init.c (scm_init_guile_1): Call scm_gc_malloc_prehistory.
5881 * threads.c (really_launch): Release heap (to prevent deadlock).
5882 (create_thread): Release heap before locking thread admin mutex.
5884 2002-12-10 Mikael Djurfeldt <mdj@kvast.blakulla.net>
5886 * threads.c (scm_i_thread_invalidate_freelists): New
5889 * gc.c (scm_igc): Call scm_i_thread_invalidate_freelists.
5891 * modules.c (scm_export): Inserted a return statement.
5893 2002-12-10 Han-Wen Nienhuys <hanwen@cs.uu.nl>
5895 * modules.c (scm_export): new function
5897 * gc-card.c: add a note about malloc()/free() overhead.
5899 2002-12-10 Mikael Djurfeldt <mdj@kvast.blakulla.net>
5901 * Makefile.am (c-tokenize.$(OBJEXT)): Don't look for c-tokenize.c
5904 2002-12-10 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5906 These changes remove scm_ints_disabled (which hasn't has any
5907 effect in Guile for quite some time).
5909 * async.c, error.h (scm_ints_disabled): Removed.
5911 * gc.c (scm_gc_for_newcell), init.c (scm_init_guile_1),
5912 root.c (scm_internal_cwdr), gdbint.c (SCM_BEGIN_FOREIGN_BLOCK,
5913 SCM_END_FOREIGN_BLOCK): Don't touch scm_ints_disabled.
5914 (old_ints): Removed.
5916 * __scm.h (SCM_DEFER_INTS, SCM_ALLOW_INTS): Define as a recursive
5918 (SCM_REDEFER_INTS, SCM_ALLOW_INTS): Define as SCM_DEFER_INTS and
5921 2002-12-09 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5923 * threads.c (scm_mutex_lock, scm_cond_wait, scm_cond_timedwait):
5924 Removed accidental #if 0 around these functions.
5926 These changes are the start of support for preemptive
5927 multithreading. Marius and I have agreed that I commit this code
5928 into the repository although it isn't thoroughly tested and surely
5929 introduces many bugs. The bugs should only be exposed when using
5930 threads, though. Signalling and error handling for threads is
5931 very likely broken. Work on making the implementation cleaner and
5932 more efficient is needed.
5934 * __scm.h (SCM_ALLOW_INTS_ONLY): Removed.
5935 (SCM_NONREC_CRITICAL_SECTION_START,
5936 SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START,
5937 SCM_REC_CRITICAL_SECTION_END): New macros.
5938 (SCM_CRITICAL_SECTION_START/END): Defined here.
5940 * eval.c: Insert SOURCE_SECTION_START / SOURCE_SECTION_END around
5941 the three calls to scm_m_expand_body.
5943 * gc.h: #include "libguile/pthread-threads.h";
5944 (SCM_FREELIST_CREATE, SCM_FREELIST_LOC): New macros.
5946 * gc.c (scm_i_freelist, scm_i_freelist2): Defined to be of type
5949 * gc.c, gc-freelist.c, inline.h: Use SCM_FREELIST_LOC for freelist
5952 * gc-freelist.c (scm_gc_init_freelist): Create freelist keys.
5954 * gc-freelist.c, threads.c (really_launch): Use
5955 SCM_FREELIST_CREATE.
5957 * gc-malloc.c (scm_realloc, scm_gc_register_collectable_memory):
5959 * gc.c (scm_i_expensive_validation_check, scm_gc,
5960 scm_gc_for_newcell): Put threads to sleep before doing GC-related
5961 heap administration so that those pieces of code are executed
5962 single-threaded. We might consider rewriting these code sections
5963 in terms of a "call_gc_code_singly_threaded" construct instead of
5964 calling the pair of scm_i_thread_put_to_sleep () and
5965 scm_i_thread_wake_up (). Also, we would want to have as many of
5966 these sections eleminated.
5968 * init.c (scm_init_guile_1): Call scm_threads_prehistory.
5970 * inline.h: #include "libguile/threads.h"
5972 * pthread-threads.h: Macros now conform more closely to the
5973 pthreads interface. Some of them now take a second argument.
5975 * threads.c, threads.h: Many changes.
5977 2002-12-09 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5979 * Makefile.am (version.h): Changed $^ --> $< in rule for
5982 2002-12-08 Rob Browning <rlb@defaultvalue.org>
5984 * version.h.in (SCM_MICRO_VERSION): use @--@ substitution now.
5985 (SCM_MINOR_VERSION): use @--@ substitution now.
5986 (SCM_MICRO_VERSION): use @--@ substitution now.
5987 (scm_effective_version): new function prototype.
5989 * version.c (scm_effective_version): new function, also add
5992 * Makefile.am (schemelibdir): VERSION -> GUILE_EFFECTIVE_VERSION.
5993 (libpath.h): use GUILE_EFFECTIVE_VERSION to compute
5995 (version.h): generate this here rather than configure.in. This
5996 approach tracks source edits better (i.e. more immediately).
5997 Might be worth considering for other .in files too.
5999 2002-12-02 Marius Vollmer <mvo@zagadka.ping.de>
6001 Reorganized thread package selection. A thread package now only
6002 implements a small set of pthread like functions and Guile
6003 implements the rest on top of that. Guile's implementation is
6004 what the "coop-pthreads" package has been previously. Support for
6005 "coop" threads has been removed until I get time to add it again.
6007 * Makefile.am (libguile_la_SOURCES): Removed iselect.c.
6008 (noinst_HEADERS): Removed coop-threads.c, coop-threads.h, coop.c,
6009 null-threads.c, coop-pthreads.c.
6010 (modinclude_HEADERS): Removed coop-defs.h, coop-pthreads.h. Added
6013 * validate.h (SCM_VALIDATE_THREAD): Moved to threads.h.
6015 * threads.h: Do not include "libguile/coop-defs.h". Include
6016 "libguile/pthread-threads.h" for USE_COPT_THREADS. Removed
6017 (previously deprecated) C level thread API prototypes. They are
6018 now in the thread package specific headers, "null-threads.h" and
6019 "pthread-threads.h".
6020 (SCM_VALIDATE_THREAD, SCM_VALIDATE_MUTEX, SCM_VALIDATE_CONDVAR):
6022 (scm_threads_init): Removed.
6023 (SCM_CRITICAL_SECTION_START, SCM_CRITICAL_SECTION_END,
6024 SCM_THREAD_SWITCHING_CODE, scm_i_switch_counter,
6025 SCM_I_THREAD_SWITCH_COUNT): Define here.
6026 (scm_single_thread_p): Removed.
6027 (scm_call_with_new_thread): Take two args directly instead of list
6029 (scm_i_thread_data, scm_i_set_thread_data, SCM_THREAD_LOCAL_DATA,
6030 SCM_SET_THREAD_LOCAL_DATA): Define here.
6032 * threads.c: Merged with "coop-pthreads.c".
6034 * null-threads.h: Implement pthread-like API as a set of macros.
6036 * pthread-threads.h: New, implement pthread-like API by deferring
6039 * init.c (scm_init_guile_1): Do not call scm_init_iselect, which
6040 has been lost in the reorganization.
6042 2002-12-01 Mikael Djurfeldt <mdj@linnaeus>
6044 The following change makes it possible to move procedure
6045 application dispatch outside inner loops. The motivation was
6046 clean implementation of efficient replacements of R5RS primitives
6049 The semantics is clear: scm_trampoline_N returns an optimized
6050 version of scm_call_N (or NULL if the procedure isn't applicable
6053 Applying the optimization to map and for-each increases efficiency
6054 noticeably. For example, (map abs ls) is 8 times faster than
6057 * eval.h (scm_t_trampoline_1, scm_t_trampoline_2): New types.
6059 * eval.c, eval.h (scm_trampoline_1, scm_trampoline_2): New functions.
6061 * eval.c (call_subr2_2, call_lsubr_2, call_closure_2): New functions;
6062 (map, for-each): Handle also application on two args as a special
6063 case; Use trampolines.
6067 * sort.c (scm_cmp_function): Choose subr2less for scm_tc7_subr_2o;
6068 (subr2oless): Removed.
6069 (scm_restricted_vector_sort_x): Use scm_return_first to keep the
6070 vector GC protected.
6072 * eval.c (check_map_args): Use scm_out_of_range_pos instead of
6075 2002-11-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
6077 * evalext.[ch] (scm_m_undefine, undefine): Deprecated.
6079 2002-11-17 Mikael Djurfeldt <mdj@linnaeus>

6083 2002-11-17 Marius Vollmer <mvo@zagadka.ping.de>
6085 * strports.c (scm_eval_string_in_module): Validate second arg to
6086 be a module. Thanks to Arno Peters!
6088 2002-11-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
6090 * .cvsignore: remove goops.c
6092 2002-11-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
6094 * modules.c (scm_env_top_level, scm_lookup_closure_module,
6095 module_variable, scm_module_lookup_closure,
6096 scm_module_transformer, scm_sym2var, scm_module_reverse_lookup,
6097 scm_system_module_env_p): Don't compare SCM values with C
6098 operators == or !=. Avoid SCM_IMP predicates. Prefer !SCM_FALSEP
6101 2002-11-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
6103 * eval.h (SCM_MAKE_ILOC): New macro.
6105 * debug.c (scm_make_iloc): Use SCM_MAKE_ILOC instead of computing
6106 the iloc bitpattern here.
6108 2002-11-14 Mikael Djurfeldt <mdj@linnaeus>
6110 * coop-pthreads.c, coop-pthreads.h: scm_internal_select should be
6111 part of the API, otherwise it's difficult to write Guile
6112 extensions using non-blocking I/O => moved #include
6113 "libguile/iselect.h" from coop-pthreads.c --> coop-pthreads.h.
6115 * coop-pthreads.c (scm_unlock_mutex): Changed s_lock_mutex -->
6118 2002-11-10 Marius Vollmer <mvo@zagadka.ping.de>
6120 * __scm.h (USE_THREADS, GUILE_ISELECT): Do not define here. They
6121 are defined in configure.in.
6123 * threads.c: Removed SCM_API from function definitions. SCM_API
6124 is only for declarations.
6126 2002-11-07 Mikael Djurfeldt <mdj@linnaeus>
6128 * coop-pthreads.h: Added support for thread specific data to the
6129 generic C API for the coop-pthreads case.
6131 * threads.c, threads.h (scm_cond_init): Undo unintentional API
6133 (scm_cond_broadcast): Added missing function.
6135 2002-11-04 Marius Vollmer <marius.vollmer@uni-dortmund.de>
6137 * coop.c (coop_next_runnable_thread): Removed, wich should have
6138 happened when GUILE_ISELECT was hard-wired.
6140 2002-11-03 Marius Vollmer <mvo@zagadka.ping.de>
6142 * Makefile.am (libguile_la_SOURCES): Added threads.c

6147 (modinclude_HEADERS): Added coop-pthreads.h.
6149 * __scm.h (USE_THREADS, GUILE_ISELECT): Define when
6150 SCM_DEBUG_DEPRECATED. Removed their use thru-out Guile.
6152 * iselect.c: Include "_scm.h" before testing HAVE_UNISTD_H.
6153 Thanks to Bill Schottstaedt!
6155 * numbers.c (scm_integer_expt): Make 0^z == 0 for z != 0.
6157 * _scm.h (HAVE_RESTARTABLE_SYSCALLS): Do define even when
6158 SCM_COPT_THREADS is defined.
6159 (SCM_SYSCALL): Use EINTR-expection version when SCM_COPT_THREADS
6162 * coop-pthreads.c: Some harmless renamings of internal stuff.
6163 (create_thread): New, generalized version of
6164 scm_call_with_new_thread.
6165 (scm_call_with_new_thread): Use it.
6166 (scm_spawn_thread): New, use create_thread.
6168 2002-11-02 Marius Vollmer <mvo@zagadka.ping.de>
6170 * coop-pthreads.c, coop-pthreads.h: Redone completely, you might
6171 start testing it now.
6173 * _scm.h: Include <errno.h< so that SCM_SYSCALL is correctly
6174 defined when HAVE_RESTARTABLE_SYSCALLS is not defined.
6175 (HAVE_RESTARTABLE_SYSCALLS): Do not define when USE_COPT_THREADS
6178 2002-10-27 Marius Vollmer <mvo@zagadka.ping.de>

6181 scm_delq_spine_x, really_install_handler, install_handler): New
6182 scheme for triggering signal handlers, to simplify take_signal.
6183 (take_signal): Simplified, to avoid race conditions.
6184 (scm_sigaction_for_thread): Use new Scheme. Validate that thread
6187 * async.c (scm_async_click): Reset pending_asyncs, handle
6188 signal_asyncs. Don't set cdr of a non-signal async to #f.
6189 (scm_i_queue_async_cell): Do not check cdr of cell for #f, queue
6190 always. Set pending_asyncs.
6191 (scm_system_async_mark_for_thread): Check that thread has not
6193 (scm_unmask_signals, decrease_block): Call scm_async_click after
6194 block_asyncs becomes zero.
6196 * __scm.h (SCM_ASYNC_CLICK): Check pending_asyncs instead of
6199 * root.h (scm_root_state): Added pending_asyncs and signal_asyncs
6201 * root.c (root_mark): Mark them.
6202 (make_root): Initialize them.
6204 * iselect.c, iselect.h: Replaced GUILE_ISELECT with
6206 (scm_internal_select): Define one version for USE_COOP_THREADS and
6207 one for USE_NULL_THREADS.
6208 (scm_init_iselect): Likewise.
6210 * inline.h (scm_cell, scm_double_cell): Also allow
6211 USE_COPT_THREADS to not protect the slot initializers.
6213 * init.c (scm_init_guile_1): Call scm_init_thread_procs. This is
6214 because threads need to be initialized before the stack, but
6215 gsubrs such as scm_timed_condition_variable_wait can only be
6218 * threads.h: Include "coop-pthreads.h" when requested.
6219 (scm_threads_make_mutex, scm_threads_lock_mutex,
6220 scm_threads_unlock_mutex, scm_threads_monitor): Removed, they were
6221 not implemented anyway.
6222 (scm_init_thread_procs, scm_try_mutex,

6236 (scm_try_mutex, scm_broadcast_condition_variable): Newly
6237 registered procedures.
6238 (scm_wait_condition_variable, scm_timed_wait_condition_variable):
6239 Use the latter as the procedure for "wait-condition-variable",
6240 thus offering a optional timeout parameter to Scheme.
6241 (scm_wait_condition_variable): Implement in terms of
6242 scm_timed_wait_condition_variable.
6243 (scm_mutex_init, scm_mutex_lock, scm_mutex_trylock,
6244 scm_mutex_unlock, scm_mutex_destroy, scm_cond_init,
6245 scm_cond_wait, scm_cond_timedwait, scm_cond_signal,
6246 scm_cond_broadcast, scm_cond_destroy): Implement in terms of
6247 scm_make_mutex, etc, and deprecate.

6258 scm_cond_wait, scm_cond_signal, scm_cond_broadcast,
6259 scm_cond_destory): Do not define, they are now deprecated and
6260 handled by threads.{h,c}.
6262 * null-threads.c (scm_null_mutex, scm_null_cond): Define here.
6263 (scm_threads_init): Create smobs here, using the appropriate
6265 (block): Removed, now unused.
6266 (scm_c_thread_exited_p): New.
6267 (scm_null_mutex_init, scm_null_mutex_lock, scm_null_mutex_unlock,
6268 scm_null_mutex_destroy, scm_null_condvar_init,
6269 scm_null_condvar_wait, scm_null_condvar_signal,
6270 scm_null_condvar_destroy): Removed and updated users to do their
6272 (scm_try_mutex, timeval_subtract,
6273 scm_timed_wait_condition_variable,
6274 scm_broadcast_condition_variable): New.
6275 (scm_wait_condition_variable): Removed.
6277 * coop-defs.h (coop_m): Added 'level' field.

6283 (coop_condition_variable_broadcast): New.
6285 * coop-threads.c (scm_threads_init): Create smobs here, using the

6300 * goops.c (hell_mutex): Reimplemented using scm_make_mutex, etc.
6302 * coop-pthreads.h, coop-pthreads.c: New, but unfinished.
6304 2002-10-21 Marius Vollmer <mvo@zagadka.ping.de>

6309 * async.c, goops.h, modules.h, validate.h (SCM_MAKE_VALIDATE_MSG):
6310 New. Use it instead of SCM_MAKE_VALIDATE in lots of places to
6311 give better error messages. Thanks to Bill Schottstaedt!
6313 2002-10-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
6315 * evalext.h, evalext.c (scm_definedp, scm_defined_p): Renamed
6316 scm_definedp to scm_defined_p and deprecated scm_definedp.
6318 2002-10-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
6320 * async.h, async.c (scm_system_async): Fixed deprecation to work
6321 correctly when deprecated features are excluded.

6334 USE_NULL_THREADS to not protect the slot initializers.
6336 * scmsigs.c (scm_sigaction_for_thread): It's "USE_THREADS" not
6339 * Makefile.am (noinst_HEADERS): Added null-threads.c.
6340 (modinclude_HEADERS): Added null-threads.h.
6342 * threads.h: Include null-threads.h when !USE_COOP_THREADS.
6343 * threads.c: Include null-threads.c when !USE_COOP_THREADS.
6344 (scm_init_threads): Use generic type names scm_t_mutex and
6345 scm_t_cond instead of coop_m and coop_c.
6347 * null-threads.c, null-threads.h: New files.
6349 2002-10-15 Marius Vollmer <mvo@zagadka.ping.de>
6351 * Makefile.am: Replaced "$<" in non-pattern rules with its value.
6352 This is to support makes that know about "$<" only in pattern
6353 rules, like Sun's make.
6355 2002-10-13 Marius Vollmer <mvo@zagadka.ping.de>
6357 * Makefile.am (libpath.h): Fixed typo in top_srcdir_absolute
6358 substitution. Thanks to David Allouche!

6362 * evalext.h: Replaced SCM_DEBUG_DEPRECATED with
6363 !SCM_ENABLE_DEPRECATED.
6365 2002-10-11 Marius Vollmer <marius.vollmer@uni-dortmund.de>
6367 * async.c (scm_system_async_mark_for_thread): Only call
6368 scm_i_thread_root when USE_THREADS is defined. Use scm_root
6371 * scmsigs.c (take_signal): Only call scm_i_thread_root when
6372 USE_THREADS is defined. Use scm_root otherwise.
6373 (scm_sigaction_for_thread): Ignore THREAD argument when
6374 USE_THREADS is not defined. Also, move THREAD argument defaulting
6375 out of HAVE_SIGACTION section, which was a bug.
6377 2002-10-10 Marius Vollmer <marius.vollmer@uni-dortmund.de>
6379 * scmsigs.c (scm_sigaction_for_thread): Store original handler in
6380 signal_handlers, not the closure that is used as the async.
6381 The closure is stored in signal_handler_cells, as previously.
6383 2002-10-10 Marius Vollmer <mvo@zagadka.ping.de>
6385 * root.h (scm_root_state): Added 'block_async' slot.
6386 (scm_active_asyncs): Removed abbrev.
6387 * root.c (scm_make_root): Initialize 'block_asyncs' slot.
6389 * __scm.h (SCM_ASYNC_TICK): Do without the scm_active_asyncs

6402 deprecation warning and check for errornous use. Set block_asyncs
6403 instead of scm_mask_ints.

6456 (scm_sigaction_for_thread): Renamed from scm_sigaction and
6457 extended to also set the thread of a signal and allocate a cell
6458 for it. Keep the Scheme name "sigaction". Check that signum is
6459 within range. Also, use SCM_VECTOR_REF instead of SCM_VELTS.
6460 (scm_sigaction): Implement in terms of scm_sigaction_for_thread.
6461 (scm_init_scmsigs): Allocate signal_handler_cells and
6462 signal_handler_threads vectors.

6568 * gc.h: remove DOUBLECELL card flags.
6570 * gc-malloc.c (scm_calloc): try to use calloc() before calling

6588 years. Thanks to Martin Grabmüller!
6590 2002-08-25 Han-Wen Nienhuys <hanwen@cs.uu.nl>
6592 * gc-segment.c (scm_i_get_new_heap_segment): use float in stead of
6593 unsigned numbers for computing minimum heap increment. This
6594 prevents weird results when a a negative minimum increment is
6597 2002-08-24 Marius Vollmer <mvo@zagadka.ping.de>
6599 * gc_os_dep.c: When we have __libc_stack_end, use that directly
6600 instead of the old tricks.
6602 * guile-snarf.in: Do not expect the input file to be the first
6603 argument after the optional "-o" option, just pass everything to
6604 the pre-processor without extracting the input file name.
6606 2002-08-23 Han-Wen Nienhuys <hanwen@cs.uu.nl>
6608 * gc-segment.c (scm_i_get_new_heap_segment): Oops. We want segment
6609 length *at* least SCM_MIN_HEAP_SEG_SIZE, not at most.
6611 2002-08-22 Han-Wen Nienhuys <hanwen@cs.uu.nl>
6613 * gc.h, gc.c: make scm_cells_allocated unsigned again. Thanks to

6626 2002-08-17 Han-Wen Nienhuys <hanwen@cs.uu.nl>
6628 * ports.c (scm_add_to_port_table): small bugfix.
6630 * mallocs.c (scm_malloc_obj): use scm_gc_malloc in stead of
6633 * gc-segment.c (scm_i_get_new_heap_segment): remove cluster cruft:
6634 only use SCM_MIN_HEAP_SEG_SIZE.
6636 * ports.c (scm_add_to_port_table): add backwards compatibility
6639 * ports.h: use scm_i_ prefix for port table and port table size.
6641 2002-08-15 Mikael Djurfeldt <mdj@linnaeus>
6643 * vports.c (scm_make_soft_port): Initialize pt variable.

6653 (scm_c_eval_string_in_module): New.
6654 Thanks to Ralf Mattes for the suggestion!
6656 2002-08-09 Han-Wen Nienhuys <hanwen@cs.uu.nl>
6658 * gc-card.c ("sweep_card"): remove SCM_MISC_ERROR messages: print
6661 * gc-mark.c ("scm_gc_mark_dependencies"): idem.
6663 * ports.c ("scm_new_port_table_entry"): return a boxed SCM in
6664 stead of scm_t_port*. The function now takes a tag argument.
6666 2002-08-08 Han-Wen Nienhuys <hanwen@cs.uu.nl>
6668 * gc.h: add scm_debug_cells_gc_interval to public interface
6670 * gc-card.c ("sweep_card"): set scm_gc_running while sweeping.
6672 * gc.c (scm_i_expensive_validation_check): separate expensive
6673 validation checks from cheap ones.

6686 * read.c (INPUT_ERROR): Prepare for file:line:column error
6687 messages for errors in scm_lreadr() and friends.
6689 2002-08-04 Han-Wen Nienhuys <hanwen@cs.uu.nl>
6691 * gc-malloc.c (scm_malloc): use scm_realloc() (simplifies
6693 (scm_gc_calloc): new function
6695 2002-08-04 Han-Wen Nienhuys <hanwen@cs.uu.nl>
6697 * ports.c (scm_new_port_table_entry): init port entry to 0
6700 * ports.c (scm_new_port_table_entry): change function from
6701 scm_add_to_port_table. This prevents cells with null-pointers from
6702 being exposed to GC.
6704 * vports.c (scm_make_soft_port) strports.c (scm_mkstrport),
6705 fports.c (scm_fdes_to_port): Use scm_new_port_table_entry().
6707 * gc.c (scm_gc_stats): add cell-yield and malloc-yield statistic
6710 * numbers.c (big2str): return "0" for 0 iso. ""
6712 * gc-segment.c, gc-malloc.c gc-mark.c, gc-freelist.c, gc-card.c,
6713 private-gc.h: new file
6715 * gc.c: completely revised and cleaned up the GC. It now uses lazy
6716 sweeping. More documentation in workbook/newgc.text
6718 2002-07-25 Marius Vollmer <marius.vollmer@uni-dortmund.de>
6720 * random.c (rstate_free): Return zero.
6722 2002-07-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
6724 * environments.c (remove_key_from_alist): Removed.
6726 (obarray_remove): Simplified.
6728 2002-07-24 Stefan Jahn <stefan@lkcc.org>
6730 * continuations.h: ia64: Include <signal.h> before
6733 2002-07-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
6735 * modules.c (scm_sym2var): Don't compare SCM values with ==.
6737 2002-07-21 Han-Wen Nienhuys <hanwen@cs.uu.nl>
6739 * goops.c (scm_compute_applicable_methods): use
6740 scm_remember_upto_here_1 iso scm_remember_upto_here
6742 * macros.c: include deprecation.h
6744 * vectors.c (scm_vector_move_right_x): remove side effect in
6746 (scm_vector_move_left_x): idem.
6748 * net_db.c, posix.c, socket.c: variable naming: change ans to
6751 * sort.c (scm_merge_vector_x): accept vector as argument
6752 iso. SCM*. This is needed for full GC correctness.
6754 * gc.h: undo previous undocumented changes related to #ifdef
6757 2002-07-20 Han-Wen Nienhuys <hanwen@cs.uu.nl>
6759 * *.c: add space after commas everywhere.
6761 * *.c: use SCM_VECTOR_SET everywhere, where a vector is written.
6762 Document cases where SCM_WRITABLE_VELTS() is used.
6764 * vectors.h (SCM_VELTS): prepare for write barrier, and let
6765 SCM_VELTS() return a const pointer
6766 (SCM_VECTOR_SET): add macro.
6768 2002-07-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
6770 * eval.c (SCM_CEVAL), macros.c (macro_print, scm_makmacro,
6771 scm_sym_macro, scm_macro_type), macros.h (scm_makmacro):
6772 Deprecated the special kind of built-in dynamic syntax transformer
6773 that was inaccurately named "macro". Note: The built-in syntax
6774 transformers that are named "mmacro" or "memoizing-macro" still
6775 exist, and it is these which come much closer to what one would
6778 2002-07-13 Neil Jerram <neil@ossau.uklinux.net>
6780 * eval.c (unmemocopy): Fix for
6781 1001-local-eval-error-backtrace-segfaults (unmemoization crash
6782 with internal definitions and local-eval).
6784 2002-07-12 Gary Houston <ghouston@arglist.com>
6786 * dynl.c: Don't define stub procedures if DYNAMIC_LINKING is not
6787 defined. They don't do anything useful, especially since the
6788 only case where DYNAMIC_LINKING is undefined seems to be
6789 when --with-modules=no is given to configure, which is basically
6790 requesting that the "dynamic linking module" be omitted.
6792 * Makefile.am (libguile_la_SOURCES): move dynl.c from
6793 libguile_la_SOURCES to EXTRA_libguile_la_SOURCES.
6795 * extensions.c (load_extension): check DYNAMIC_LINKING for
6797 * init.c (scm_init_guile_1): check DYNAMIC_LINKING for
6798 scm_init_dynamic_linking.
6800 2002-07-10 Marius Vollmer <mvo@zagadka.ping.de>
6802 * guile.c, iselect.h, net_db.c, posix.c, socket.c: No need to
6803 check for Cygwin when including <winsock2.h>, this is already
6804 check for by configure. Thus, revert change from 2002-07-07.
6806 2002-07-10 Gary Houston <ghouston@arglist.com>
6808 * eq.c: include <string.h>
6809 * dynl.c: docstring editing.
6811 2002-07-09 Gary Houston <ghouston@arglist.com>
6813 * dynl.c (scm_dynamic_call): docstring editing.
6815 2002-07-08 Rob Browning <rlb@defaultvalue.org>
6817 * gc_os_dep.c: HURD fixes.
6819 2002-07-07 Marius Vollmer <mvo@zagadka.ping.de>
6821 Crosscompiling and Cygwin fixes by Jan Nieuwenhuizen. Thanks!
6823 * Makefile.am: Override default rule for c-tokenize.$(OBJECT);
6824 this should be compiled for BUILD host.
6825 Override default rule for
6826 guile_filter_doc_snarfage$(EEXECT); this should run on BUILD host.
6827 Add missing $(EXEEXT) to guile_filter_doc_snarfage invocation.
6828 (snarf2checkedtexi): Use GUILE_FOR_BUILD instead of preinstguile.
6830 * guile.c, iselect.h, net_db.c, posix.c, socket.c: Do not include
6831 <winsock2.h> on Cygwin even when we have it.
6833 2002-07-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
6835 * __scm.h (SCM_CAUTIOUS), eval.c (scm_eval_args, deval_args,
6836 SCM_CEVAL): Removed compile time option SCM_CAUTIOUS to clean up
6837 the code. Full number of arguments checking of closures is
6838 mandatory now. However, the option to disable the checking has
6839 most probably not been used anyway.
6841 2002-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
6843 * __scm.h (SCM_RECKLESS), backtrace.c (SCM_ASSERT), debug.c
6844 (scm_debug_options), eval.c (scm_lookupcar, scm_lookupcar1,
6845 scm_badargsp, SCM_CEVAL, SCM_APPLY, scm_map, scm_for_each),
6846 feature.c (scm_init_feature), gsubr.c (scm_gsubr_apply), numbers.c
6847 (scm_logand, scm_logior, scm_logxor, scm_i_dbl2big), srcprop.c
6848 (scm_source_properties, scm_set_source_properties_x,
6849 scm_source_property): Removed compile time option SCM_RECKLESS to
6850 clean up the code. Full number of arguments checking of closures
6851 is mandatory now. However, the option to disable the checking has
6852 most probably not been used anyway.
6854 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
6855 scm_source_property): Use !SCM_CONSP instead of SCM_NCONSP.
6857 2002-06-30 Gary Houston <ghouston@arglist.com>
6859 * dynl.c: Removed all SCM_DEFER_INTS/SCM_ALLOW_INTS, which won't
6860 do anything useful. Added a comment about need for a mutex if
6861 pre-emptive threading is supported.
6863 * posix.c (scm_convert_exec_args), dynl.c
6864 (scm_make_argv_from_stringlist): static procs: 1) renamed both to
6865 allocate_string_pointers. 2) simplified: don't reallocate the
6866 strings, just make an array of pointers 3) avoid memory leaks on
6867 error 4) let the procedure report errors in its own name.
6868 Consequences: 1) the procedures now assume that SCM strings are
6869 nul-terminated, which should always be the case. 2) Since strings
6870 are not reallocated, it's now possible for strings passed to
6871 dynamic-args-call to be mutated.
6873 2002-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
6875 * __scm.h, eval.c, eval.h: Removed compile time option
6876 MEMOIZE_LOCALS to clean up the code. Now, caching of local
6877 variable positions during memoization is mandatory. However, the
6878 option to disable the caching has most probably not been used
6881 2002-06-18 Marius Vollmer <mvo@zagadka.ping.de>
6883 * print.c (scm_simple_format): Print missing part of format before
6884 ~% control. Thanks to Daniel Skarda!
6886 2002-06-01 Marius Vollmer <mvo@zagadka.ping.de>
6888 * mkstemp.c: Added exception notice to license statement.
6890 2002-05-22 Marius Vollmer <mvo@zagadka.ping.de>
6892 * numbers.c (mem2ureal): When returning an inexact zero, make sure
6893 it is represented as a floating point value so that we can change
6896 From John W. Eaton <jwe@bevo.che.wisc.edu>
6898 * numbers.c (idbl2str): Don't omit sign when printing negative zero.
6900 2002-05-14 Thien-Thi Nguyen <ttn@giblet.glug.org>
6902 * gc_os_dep.c: For I386/OPENBSD, allow for `__i386__'
6903 in addition to `i386'. Thanks to Dale P. Smith.
6905 2002-05-08 Marius Vollmer <mvo@zagadka.ping.de>
6907 * eq.c (real_eqv): New.
6908 (scm_eqv_p): Use it when comparing reals and complexes.
6910 * numbers.c: Include <string.h>, for strncmp.
6911 (mem2complex): Do not create negative NaNs.

6918 * posix.c (scm_putenv): Handle removing variables explicitely by
6923 * numbers.h: Conditionally include floatingpoint.h, ieeefp.h, and

6933 (guile_ieee_init): New function.
6934 (scm_inf, scm_nan): New functions.

6936 corresponding gotos.
6937 (ALLOW_DIVIDE_BY_ZERO): New macro.
6938 (scm_divide): Allow division by zero to occur if
6939 ALLOW_DIVIDE_BY_ZERO is defined.
6940 Handle bignums and ints as special cases.
6942 Additional stuff by me:

6975 2002-04-16 Marius Vollmer <mvo@zagadka.ping.de>
6977 * guile-snarf.in: Do not clean input file. This would write to
6978 the $(srcdir) during a VPATH build, which is not allowed. It also
6979 isn't needed since it only works when an output filename has been
6980 specified and in that case we don't need to clean the input file
6981 because the output file will already exist.
6983 2002-03-31 Marius Vollmer <mvo@zagadka.ping.de>

7020 stdout. When no "-o" option is given, use "-" as the output
7021 filename (i.e., stdout). Only 'clean' the inputfile or remove the
7022 output file on error when the output file name is not "-". Define
7023 the preprocessor macro SCM_MAGIC_SNARFER while snarfing.
7025 * Makefile.am (.c.x): Pass "-o $@" to guile-snarf.

7040 * eval.c (SIDEVAL): Removed.
7042 (SCM_CEVAL): Minimized scope of variable orig_sym. Eliminated
7043 goto-labels cdrxnoap, cdrxbegin and nontoplevel_cdrxnoap. Changed
7044 argument checking order for set! to locals, variables and symbols.

7077 scm_select, scm_basename), goops.c (scm_method_generic_function),
7078 numbers.c (scm_integer_length), posix.c (scm_getgroups, scm_execl,
7079 scm_setlocale, scm_flock), socket.c (scm_shutdown): Correct
7082 * debug.c (scm_debug_options), eval.c
7083 (scm_eval_options_interface), read.c (scm_read_options): Change

7129 2002-03-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
7131 * eval.c (SCM_CEVAL): Got rid of the last reference to t.lloc.
7132 The next step will be to remove the union 't' and simplify the
7133 code of SCM_CEVAL that way.
7135 2002-03-12 Neil Jerram <neil@ossau.uklinux.net>
7137 * iselect.c (collisionp, gnfds, greadfds, gwritefds, gexceptfds,

7164 arg2. Removed some uses of t.arg1, t.lloc and proc as temporary
7165 variables. Introduced temporary variables with hopefully
7166 descriptive names for clarification. Replaced SCM_N?IMP by a more
7167 explicit predicate in some places. Use SCM_INSTANCE_HASH instead
7168 of computing the expression explicitly. Eliminate now unused

7188 of SCM_MAX_FRAME_SIZE as a bit mask; it isn't used like this.
7190 * eval.c (SCM_CEVAL): Don't store scm_debug_eframe_size in
7191 debug.status. It isn't needed, and it can overflow the bits

7866 magnituse first into a unsigned type, and correctly check for
7868 (INTEGRAL2BIG): Do not use MIN_VALUE explicitely by observing that

7910 and makes them available through Guile. That is because the
7911 Winsock-API does not store its errors in `errno' and thus cannot
7912 return error messages via `strerror (errno)'.
7914 * socket.c (scm_init_socket): Initialize `win32-socket' part
7915 here under M$-Windows.
7917 * numbers.h: Added missing declaration of
7918 `scm_sys_check_number_conversions()'.
7920 * error.c: Local definition of SCM_I_STRERROR and SCM_I_ERRNO
7921 and use in `(strerror)' and `(system-error)'.
7923 * Makefile.am (EXTRA_libguile_la_SOURCES): Added
7924 `win32-socket.[ch]' to extra source and header files.
7926 2001-11-06 Marius Vollmer <mvo@zagadka.ping.de>
7928 * script.c (scm_shell_usage, scm_compile_shell_switches): Prepend
7929 a call to turn-on-debugging when --debug has been given instead of
7930 turning it on directly. Also, handle new `--no-debug' option,
7931 which might suppress the call to turn-on-debugging.
7933 2001-11-05 Stefan Jahn <stefan@lkcc.org>
7935 * struct.c (s_scm_struct_vtable_p): Corrected docstring.
7937 2001-11-04 Stefan Jahn <stefan@lkcc.org>
7939 * Makefile.am (libguile_la_LIBADD): Added $(THREAD_LIBS_LOCAL)
7940 here (was at guile_LDADD) which describes the dependency
7941 correctly and allows a clean build on Win32.
7943 * __scm.h (SCM_API): Follow-up patch. Renamed __FOO__ macros
7946 * __scm.h: USE_DLL_IMPORT indicates the usage of the DLL
7947 import macros for external libraries (libcrypt, libqthreads,
7948 libreadline and libregex).
7950 * coop-defs.h: Include <winsock2.h> for `struct timeval'.
7952 * posix.c (flock): Added support for flock() in M$-Windows.
7954 * guile.c (SCM_IMPORT): Follow-up patch. Use SCM_IMPORT instead
7957 * fports.c (getflags): Differentiate reading and writing pipes
7960 * filesys.c (S_IS*): Redefine all of the S_IS*() macros for
7963 * coop.c (coop_condition_variable_timed_wait_mutex): Use
7964 conditionalized error code if `ETIMEDOUT' is not available.
7965 (scm_thread_usleep): Remove bogus declaration of `struct timeval
7968 * numbers.c (PTRDIFF_MIN): Moved this definition where it actually
7969 belongs. That is because NO_PREPRO_MAGIC gets undefined after
7970 each inclusion of `num2integral.i.c'.
7971 (SIZE_MAX): Define NO_PREPRO_MAGIC if SIZE_MAX is undefined.
7973 2001-11-03 Marius Vollmer <mvo@zagadka.ping.de>
7975 * eval.c (scm_m_begin): Allow `(begin)`, with no subforms.
7976 (SCM_CEVAL): Evaluate an empty `begin' to SCM_UNSPECIFIED.
7978 2001-11-02 Mikael Djurfeldt <mdj@linnaeus>
7980 * print.c (scm_iprin1): Mark print state as revealed when
7981 dispatching to generic write or display.
7983 * unif.c (scm_ra2contig): Fixed memory overwrite bug.
7985 2001-11-02 Marius Vollmer <mvo@zagadka.ping.de>
7987 Support for native Win32. Thanks to Stefan Jahn!
7989 * Makefile.am: Add win32-uname.c, win32-uname.h, win32-dirent.c
7990 and win32-dirent.h to extra source and header files. These
7991 include the uname() and the POSIX dirent interface implementation
7992 for M$-Windows. Put `-no-undefined' into LDFLAGS to support
7993 linkers which do not allow unresolved symbols inside shared
7994 libraries. Corrected `guile_filter_doc_snarfage$(EXEEXT)'
7997 * __scm.h: Defined SCM_API. This macro gets prepended to all
7998 function and data definitions which should be exported or imported
7999 in the resulting dynamic link library in the Win32 port.
8001 * __scm.h, alist.h, arbiters.h, async.h, backtrace.h, boolean.h,
8002 chars.h, continuations.h, coop-defs.h, coop-threads.h,
8003 debug-malloc.h, debug.h, deprecation.h, dynl.h, dynwind.h,
8004 environments.h, eq.h, error.h, eval.h, evalext.h, extensions.h,
8005 feature.h, filesys.h, fluids.h, fports.h, gc.h, gdb_interface.h,
8006 gdbint.h, gh.h, goops.h, gsubr.h, guardians.h, hash.h, hashtab.h,
8007 hooks.h, init.h, ioext.h, iselect.h, keywords.h, lang.h, list.h,
8008 load.h, macros.h, mallocs.h, modules.h, net_db.h, numbers.h,
8009 objects.h, objprop.h, options.h, pairs.h, ports.h, posix.h, print.h,
8010 procprop.h, procs.h, properties.h, ramap.h, random.h, rdelim.h,
8011 read.h, regex-posix.h, root.h, rw.h, scmsigs.h, script.h, simpos.h,
8012 smob.h, socket.h, sort.h, srcprop.h, stackchk.h, stacks.h, stime.h,
8013 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
8014 tags.h, threads.h, throw.h, unif.h, values.h, variable.h, vectors.h,
8016 Prefixed each each exported symbol with SCM_API.
8018 * continuations.c: Added comment about the use of the extern
8019 declarations of {get,set}context() functions used in the ia64 port.
8021 * continuations.h, gc.c: `__libc_ia64_register_backing_store_base'
8022 is meant to be a `unsigned long *'.
8024 * filesys.c: Include `direct.h' if possible. Use local
8025 `win32-dirent.h' for the native M$-Windows port. Define S_IS*()
8026 macros for M$-Windows. Implementation of `fstat_Win32()' which is
8027 able to differentiate between sockets and other file descriptors.
8028 Use this function as wrapper in `scm_fstat()'. Fixed typo in
8031 * fports.c: Include `io.h' is possible. Put `*fp' into referring
8032 statement block in `scm_fport_buffer_add()'.
8033 Some corrections in `getflags()'.
8035 * gdb_interface.h (GDB_INTERFACE): Also support __CYGWIN__.
8037 * guile.c: Make sure to define __SCM_IMPORT__ for shared library
8038 build on Win32. Disable preloaded symbols on Win2 platforms.
8040 * ioext.c, ports.c: Include `io.h' is possible.
8042 * mkstemp.c: Include `process.h' is possible.
8044 * net_db.c: Disable extern declaration of `h_errno' for __CYGWIN__,
8046 Put `scm_return_entry()' into HAVE_GETSERVENT conditional.
8048 * posix.c: Remove unnecessary dirent includes and defines. Include
8049 local `win32-uname.h' for MinGW. Extern declaration of
8050 `mkstemp()' for systems where it does not exists. Make
8051 `getlogin()' available on M$-Windows.
8053 * scmsigs.c: Made `usleep()' avalable on MinGW.
8055 * stime.c: On M$-Windows `tzname[]' is known to be `_tzname[]'.
8057 * win32-dirent.c: Include "win32-dirent.h", not "dirent.h".
8059 * win32-uname.c: Include "win32-uname.h", not "uname.h".
8061 2001-10-28 Mikael Djurfeldt <mdj@linnaeus>
8063 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write):
8064 Don't apply scm_uniform_vector_length on arrays.
8066 2001-10-14 Dirk Herrmann <D.Herrmann@tu-bs.de>
8068 * eval.c (scm_lookupcar, scm_m_letstar, scm_m_do, iqq,
8069 scm_m_define, scm_m_letrec1, scm_m_let, scm_m_expand_body,
8070 scm_macroexp, unmemocopy, scm_eval_args, scm_deval_args,
8071 SCM_CEVAL, scm_map, scm_init_eval): When building lists, prefer
8072 scm_list_<n> over scm_cons[2]?.
8074 (scm_unmemocar, scm_m_cond, scm_m_letstar, scm_m_letrec1,
8075 scm_m_let, scm_m_atbind, unmemocopy, SCM_CEVAL, SCM_APPLY): Use
8076 SCM_C[AD][AD]R instead of explicit form.
8078 (scm_m_set_x, scm_m_cond, scm_m_letstar, scm_m_do): Reordered
8079 comparison parameters.
8081 (scm_m_case, scm_m_cond, scm_m_letstar, scm_m_do, SCM_CEVAL): Use
8082 !SCM_NULLP instead of SCM_NIMP.
8084 (scm_m_case): Don't copy the form. Renamed proc to clause and
8085 minimized its scope. Renamed x to clauses. Removed side
8086 effecting operation from macro call.
8088 (scm_m_cond): Don't copy the form. Renamed arg1 to clause and
8089 minimized its scope. Renamed x to clauses. Minimized the scope
8090 of variable 'len'. Make sure the else clause is treated specially
8091 even in case of '=>' occurences. Don't change the else to #t in
8092 order to be able to distinguish this case in the evaluator. Leave
8093 type checking of the recipient to the evaluator.
8095 (scm_c_improper_memq): Made the comment somewhat clearer.
8097 (scm_m_lambda): Renamed proc to formals. Removed unnecessary
8098 test for SCM_IM_LET at the place of the formal parameters.
8099 Simplified the formal parameter checking.
8101 (scm_m_letstar): Added Comment. Renamed proc to bindings.
8102 Renamed arg1 to binding and minimized its scope. Eliminated
8103 unnecessary consing.
8105 (scm_m_do): Renamed proc to bindings. Minimized the scope of
8108 (build_binding_list): New static function.
8110 (unmemocopy): Don't use SCM_TYP7 on pairs (it's unclean).
8111 Further, split up the 'letrec' unmemoizing code to the
8112 corresponding parts for 'do', 'let' and 'letrec', adding comments
8113 to each form. Cleanup the handling of the do form (This removes
8114 some *real* code :-).
8116 (SCM_CEVAL): Removed side effecting operation from macro call.
8117 Handle the 'else clause of the 'cond form specially - the symbol
8118 'else is not replaced with #t any more.
8120 2001-10-14 Gary Houston <ghouston@arglist.com>
8122 * version.c (scm_version): use sprintf instead of snprintf,
8123 for portability. thanks to Bill Schottstaedt.
8125 2001-10-14 Mikael Djurfeldt <mdj@linnaeus>
8127 * read.c (scm_lreadr): When user-defined hash procedure returns
8128 SCM_UNSPECIFIED: Fall back to standard handling instead of raising
8129 an exception. (This prevents parsing of uniform vectors from
8130 interfering with parsing of numbers.)
8132 2001-10-13 Marius Vollmer <mvo@zagadka.ping.de>
8134 * numbers.c: Set NO_PREPRO_MAGIC when defining our version of
8135 PTRDIFF_MIN. Thanks to Ken Raeburn.
8137 2001-10-07 Marius Vollmer <mvo@zagadka.ping.de>
8139 * Makefile.am (EXTRA_libguile_la_SOURCES): Added "mkstemp.c".
8141 * eval.c (scm_m_atbind): First try to find the variable without
8142 defining it locally; when it has not been found, define it
8145 * modules.c (module_variable): Pass over variables that exist but
8148 2001-10-06 Marius Vollmer <mvo@zagadka.ping.de>
8150 * backtrace.c (display_backtrace_file_and_line): Only use
8151 scm_basename when POSIX support is compiled in. Thanks to Chris
8154 2001-10-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
8156 * numbers.c (mem2uinteger): Return number read so far when coming
8157 across a hexdigit after having read a # or if not reading a hex
8158 value. This will enable the calling code to correctly handle
8159 forms like 1e2. (The background is, that the exponent markers d,
8160 e and f are also hexdigits.) Thanks to Mikael Djurfeldt for
8161 providing this patch.
8163 (mem2complex): Fix erroneous double-negation. Now, numbers like
8164 1-i will be read correctly.
8166 2001-10-12 Mikael Djurfeldt <mdj@linnaeus>
8168 * debug.c (scm_mem_to_proc): Fixed typo in previous change.
8170 * validate.h (SCM_VALIDATE_DOUBLE_DEF_COPY): New macro.
8172 2001-10-12 Dirk Herrmann <D.Herrmann@tu-bs.de>
8174 * print.c (scm_print_state_vtable, print_state_pool):
8175 Initialize. These variables are now registered as gc roots.
8177 (scm_current_pstate): Update documentation.
8179 (scm_current_pstate, scm_make_print_state, scm_free_print_state,
8180 scm_prin1, scm_init_print): print_state_pool is registered as a
8181 gc root and thus does not need to be protected by a surrounding
8184 (make_print_state): The car of print_state_pool no longer holds
8185 the scm_print_state_vtable.
8187 (scm_current_pstate, scm_make_print_state, print_circref,
8188 scm_iprin1, scm_prin1, scm_iprlist): Prefer !SCM_<foo> over
8191 (scm_prin1): When building lists, prefer scm_list_<n> over
8194 (scm_iprlist): Removed a redundant SCM_IMP test.
8196 (scm_simple_format): Use SCM_EQ_P to compare SCM values.
8198 2001-10-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
8200 * debug.c (scm_make_iloc): Prefer !SCM_<foo> over SCM_N<foo>.
8202 (scm_memcons, scm_mem_to_proc): When building lists, prefer
8203 scm_list_<n> over scm_cons[2]?.
8205 (scm_mem_to_proc): Prefer SCM_CONSP over SCM_NIMP.
8207 (scm_procedure_name): Use SCM_CADR instead of explicit form.
8209 (debugobj_print): Coerce scm_intprint arg 1 to long, not int.
8210 Thanks to Rob Browning for the patch (see log entry 2001-09-21) -
8211 for some reason his patch didn't make it into the cvs.
8213 2001-10-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
8215 * numbers.c (mem2decimal_from_point): Cleaned up the parsing a
8216 little bit - should even be somewhat more accurate now.
8218 2001-10-08 Rob Browning <rlb@defaultvalue.org>
8220 * gc.c: support ia64 register backing store.
8221 (SCM_MARK_BACKING_STORE): new macro.
8223 * continuations.h: support ia64 register backing store.
8224 (struct scm_t_contregs): add ia64 register backing store.
8226 * continuations.c: support ia64 register backing store.
8227 (continuation_mark): mark ia64 register backing store.
8228 (continuation_free): free ia64 register backing store.
8229 (scm_make_continuation): capture ia64 register backing store.
8230 (copy_stack_and_call): copy ia64 register backing store.
8232 2001-10-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
8234 * hashtab.c (scm_hash_fn_create_handle_x): The result of assoc_fn
8235 is known to be #f if no entry is found. Thus, use !SCM_FALSEP
8236 instead of SCM_NIMP to test for that case.
8238 * strings.h (SCM_SET_STRING_LENGTH): Cast the length to
8239 scm_t_bits instead of long.
8241 2001-10-06 Marius Vollmer <mvo@zagadka.ping.de>
8243 * tags.h (SCM_T_BITS_MAX, SCM_T_SIGNED_BITS_MAX,
8244 SCM_T_SIGNED_BITS_MIN): New.
8245 * numbers.h (SCM_MOST_POSITIVE_FIXNUM, SCM_MOST_NEGATIVE_FIXNUM):
8246 Use them to make these macros computable by the preprocessor.
8248 * num2integral.i.c (INTEGRAL2NUM): Let the preprocessor test
8249 whether the integral type fits in a fixnum, not the compiler.
8250 This removes a spurious compiler warning. Also, honor the
8251 NO_PREPRO_MAGIC flag to suppress any preprocessor tests. This is
8252 needed for `long long's.
8254 * numbers.c: Define NO_PREPRO_MAGOC when including
8255 num2integral.c.i for `long long' and `signed long long'.
8257 2001-10-06 Mikael Djurfeldt <mdj@linnaeus>
8259 These changes fixes a race condition in the Guile coop - pthread
8262 * coop.c (mother_awake_p): New variable.
8263 (coop_create): Set mother_awake_p before creating or signalling
8264 mother; wait until mother is going to sleep before returning.
8265 (mother): Reset mother_awake_p before going to sleep.
8267 2001-10-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
8269 * options.c (protected_objects, scm_init_options): The content of
8270 protected_objects is now protected from garbage collection using
8271 scm_gc_register_root instead of scm_permanent_object.
8273 (get_option_setting): New static function that computes an option
8274 setting as it was formerly done in the function scm_options.
8276 (get_documented_option_setting): New static function that
8277 returns option documentation as it was formerly done in the
8278 function scm_options. Note that documentation C strings are no
8279 longer precomputed into SCM objects. Instead, they are converted
8280 into SCM strings every time get_documented_option_setting is
8283 (change_option_setting): New static functions that modifies the
8284 option setting as it was formerly done in the function
8285 scm_options. The function is now exception safe, i. e. won't
8286 cause a memory leak when interrupted. Further, only non-immediate
8287 option values are added to the protection list.
8289 (scm_options): This function now has only the purpose to dispatch
8290 to to get_option_setting, get_documented_option_setting or
8291 change_option_setting, depending on the arguments given to
8294 (scm_init_opts): Don't convert documentation C strings into SCM
8295 strings. Further, don't protect any object values: They _must_
8296 be immediate values, otherwise there is no guarantee that they
8297 have not been collected before anyway.
8299 * options.[ch] (scm_t_option): Made type unsigned, name into a
8300 constant char* and val into a scm_t_bits type.
8302 (scm_options, scm_init_opts): The number of options is guaranteed
8303 to be larger or equal to zero. Thus, the type is changed to
8306 2001-10-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
8308 * num2integral.i.c (NUM2INTEGRAL): Eliminated some warnings about
8309 testing an unsigned value for being >= 0.
8311 2001-10-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
8313 * numbers.h: Removed old comment about using SCM_CAR to access
8316 (SCM_MOST_POSITIVE_FIXNUM, SCM_MOST_NEGATIVE_FIXNUM): Make sure
8317 the return value is signed. Thanks to Brian Crowder for the bug
8320 (SCM_SRS): Avoid unnecessary casting and don't unpack input
8321 values. With this patch, SCM_SRS can be safely used for other
8322 types than scm_t_signed_bits. However, it should still better be
8323 an internal macro and thus be renamed to SCM_I_SRS.
8325 (SCM_MAKINUM, SCM_INUM): Use proper casting.
8327 2001-10-03 Gary Houston <ghouston@arglist.com>
8329 * continuations.h, unif.h: in the descriptions of the bit patterns
8330 of the heap cells, make bit 0 the least significant.
8332 2001-09-25 Thien-Thi Nguyen <ttn@glug.org>
8334 * chars.h (SCM_MAKE_CHAR): Use `scm_t_bits' instead of `intptr_t'.
8335 Thanks to Golubev I. N.
8337 2001-09-25 Gary Houston <ghouston@arglist.com>
8339 * ports.c (scm_drain_input): extended the docstring. thanks to
8340 Alex Schroeder and Thien-Thi Nguyen.
8342 2001-09-23 Mikael Djurfeldt <mdj@linnaeus>
8344 * validate.h (SCM_NUM2FLOAT, SCM_NUM2DOUBLE,
8345 SCM_VALIDATE_FLOAT_COPY, SCM_VALIDATE_DOUBLE_COPY): New
8346 macros. (The NUM names might soon change.)
8348 * numbers.h: Added missing declarations.
8350 2001-09-22 Mikael Djurfeldt <mdj@linnaeus>
8352 * Makefile.am: Distribute num2float.i.c.
8354 * num2float.i.c: New file, multiply included by numbers.c, used
8355 to "templatize" the float <-> num conversion routines.
8357 * numbers.c: New functions: scm_num2float, scm_float2num,
8358 scm_num2double, scm_double2num.
8360 2001-09-21 Rob Browning <rlb@defaultvalue.org>
8362 * .cvsignore: really add version.h
8364 * strings.h (SCM_SET_STRING_LENGTH): coerce "l" to a long.
8365 Otherwise it fails on the alpha. However, we might rather choose
8366 this size conditionally.
8368 * numbers.c (scm_gcd): change "k" to a long from an int.
8369 Otherwise it fails on the alpha. However, we might rather choose
8370 this size conditionally.
8372 * error.c (scm_wta): coerce char* to intptr_t before int
8375 * debug.c (debugobj_print): coerce scm_intprint arg 1 to long, not
8378 * chars.h (SCM_MAKE_CHAR): coerce value to intptr_t.
8380 2001-09-20 Mikael Djurfeldt <mdj@linnaeus>
8382 * numbers.c (scm_integer_expt): Accept inexact integer in second
8383 argument. (Thanks to Bill Schottstaedt.)
8385 2001-09-20 Rob Browning <rlb@defaultvalue.org>
8387 * .cvsignore: add version.h
8389 * versiondat.h.in: removed (obsolete).
8391 * version.h.in: renamed from version.h.
8392 (SCM_GUILE_MAJOR_VERSION): new public macro.
8393 (SCM_GUILE_MINOR_VERSION): new public macro.
8394 (SCM_GUILE_MICRO_VERSION): new public macro.
8396 * version.h: renamed to version.h.in.
8399 (scm_major_version): support integer *_VERSION macros.
8400 (scm_minor_version): support integer *_VERSION macros.
8401 (scm_micro_version): support integer *_VERSION macros.
8402 (scm_version): support integer *_VERSION macros.
8404 2001-09-20 Mikael Djurfeldt <mdj@linnaeus>
8406 * error.c, error.h: Made error keys globally accessible.
8407 Applications might want to test for these or use them in a direct
8410 * num2integral.i.c (NUM2INTEGRAL): Report an error when these
8411 routines are passed an inexact. This change in behavior is
8412 motivated by concordance with R5RS: It is more common that a
8413 primitive doesn't want to accept an inexact for an exact.
8415 2001-09-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
8417 The following patch partially undoes my patch from 2001-06-30,
8418 where I added the function scm_gc_mark_cell_conservatively. The
8419 function is buggy, since it breaks guile during conservative
8420 marking if a pointer on the stack points directly into the list of
8421 free cells on the heap: With conservative cell marking this will
8422 cause the whole free list to be scanned and marked - boom!
8424 * gc.c (allocated_mark, MARK, heap_segment,
8425 scm_gc_mark_cell_conservatively, scm_init_storage), gc.h
8426 (scm_gc_mark_cell_conservatively): Remove function
8427 scm_gc_mark_cell_conservatively and update the corresponding
8428 comments and uses accordingly. Thanks to Christopher Cramer for
8429 the patch. (Minor corrections by me.)
8431 2001-09-15 Gary Houston <ghouston@arglist.com>

9006 hold predefined symbols.
9008 (build_class_class_slots): Build the list using scm_list_n
9009 instead of cons. Also, slots are already created as lists, thus
9010 making a call to maplist unnecessary.

9115 * strports.c (scm_read_0str, scm_eval_0str): Call
9116 scm_c_read_string and scm_c_eval_string respectively, not
9117 themselves. Thanks to Dale P. Smith!
9119 2001-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
9121 * unif.c (scm_array_set_x): The variable args does not
9122 necessarily have to be a list. Further, got rid of a redundant
9125 2001-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
9127 * list.c (SCM_I_CONS): Make sure the cell type is initialized

9135 * weaks.h (WEAKSH, SCM_WEAKS_H): Rename <foo>H to SCM_<foo>_H.
9137 (SCM_WVECTP): Prefer !SCM_<pred> over SCM_N<pred>.
9139 The following patch adds conservative marking for the elements of
9140 free or allocated cells.
9142 * gc.c (allocated_mark, heap_segment): New static functions.
9144 (which_seg): Deleted, since the functionality is now provided by

9149 (MARK): If cell debugging is disabled, mark free cells
9152 (scm_mark_locations, scm_cellp): Extracted the search for the
9153 heap segment of a SCM value into function heap_segment.
9155 (scm_init_storage): Allocated cells must be marked

9160 The following patch changes the representation of weak vectors to
9161 double cells instead of using an extension of the vector's
9164 * gc.c (MARK): Use SCM_SET_WVECT_GC_CHAIN instead of assigning to
9165 the result of SCM_WVECT_GC_CHAIN.
9167 (scm_gc_sweep): Weak vectors don't have extra fields any more.
9169 * weaks.c (allocate_weak_vector): New static function. It does
9170 not patch any previously created vector object during the
9171 construction of a weak vector, and thus doesn't need to switch
9172 off interrupts during vector creation.
9174 (scm_make_weak_vector, scm_make_weak_key_hash_table,
9175 scm_make_weak_value_hash_table, scm_make_doubly_weak_hash_table):
9176 Use allocate_weak_vector to provide the new weak vector object.
9178 * weaks.h (SCM_WVECT_TYPE, SCM_SET_WVECT_TYPE,
9179 SCM_SET_WVECT_GC_CHAIN): New macros. The weak vector subtype is
9180 now stored in the double cell.
9182 (SCM_IS_WHVEC, SCM_IS_WHVEC_V, SCM_IS_WHVEC_B, SCM_IS_WHVEC_ANY):
9185 (SCM_WVECT_GC_CHAIN): The weak objects are now chained together
9186 using an entry of the double cell.
9188 2001-06-30 Thien-Thi Nguyen <ttn@revel.glug.org>
9190 * stamp-h.in: bye bye
9192 2001-06-30 Marius Vollmer <mvo@zagadka.ping.de>
9194 * gh_eval.c (gh_eval_str): Use scm_c_eval_string instead of
9197 * load.c, load.h (scm_c_primitive_load,
9198 scm_c_primitive_load_path): New.
9200 * strports.c, strports.h (scm_c_read_string): Renamed from

9220 * strings.c: #include "libguile/deprecation.h".
9222 2001-06-27 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
9224 * read.c (scm_lreadr): When reading a hash token, check for a
9225 user-defined hash procedure first, so that overriding the builtin
9226 hash characters is possible (this was needed for implementing
9227 SRFI-4's read synax `f32(...)').
9229 * num2integral.i.c: Use scm_t_signed_bits instead of scm_t_bits,
9230 because the latter is unsigned now and breaks comparisons like
9231 (n < (scm_t_signed_bits)MIN_VALUE).
9233 2001-06-26 Neil Jerram <neil@ossau.uklinux.net>
9235 * eval.h, eval.c (scm_call_4): New function.
9237 * eval.c (SCM_APPLY, SCM_CEVAL, ENTER_APPLY): Call trap handlers
9238 directly rather than dispatching to them via scm_ithrow and a lazy

9246 procedures not being #f.
9248 2001-06-27 Michael Livshin <mlivshin@bigfoot.com>

9251 (EXTRA_DIST): add c-tokenize.lex, so it gets distributed.
9253 filter-doc-snarfage.c: remove.
9255 2001-06-26 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
9257 * ports.c (scm_output_port_p): Use result of SCM_COERCE_OUTPORT.
9259 The following set of changes makes compiling Guile under various
9260 Windows compilers easier. Compilation under GNU systems should
9261 not be affected at all.
9263 Thanks to Stefan Jahn for all necessary information, patches and

9293 initialized statically. Initialize at runtime instead.
9295 * fports.c (write_all): ssize_t -> size_t.
9296 (fport_print): Conditionalize call to ttyname().
9297 (getflags): New function, compiled only under Windows.

9833 * gh_data.c (gh_set_substr): Removed redundant unsigned >= 0
9834 text, removed redundant computation of effective_length and fixed
9837 * goops.c (test_slot_existence): Use SCM_EQ_P to compare SCM
9840 (wrap_init): Don't use SCM_C[AD]R for non pairs.
9842 (hell): Make it a scm_bits_t pointer rather than a SCM pointer.
9844 * goops.c (scm_sys_modify_class), strports.c (st_resize_port),
9845 struct.h (SCM_SET_STRUCT_PRINTER): Store unpacked values.
9847 * goops.h (SCM_ACCESSORS_OF, SCM_SLOT): Return a SCM value.
9849 * goops.h (GOOPSH, SCM_GOOPS_H), modules.h (MODULESH,
9850 SCM_MODULES_H), objects.h (OBJECTSH, SCM_OBJECTS_H), struct.h
9851 (STRUCTH, SCM_STRUCT_H), symbols.h (SYMBOLSH, SCM_SYMBOLS_H),

9867 * tags.h (SCM_VOIDP_TEST): Removed.
9869 (SCM_DEBUG_TYPING_STRICTNESS): Now takes values 0, 1, 2. The
9870 value of 2 now corresponds to the former 1, the current 1
9871 corresponds to the former situation that SCM_VOIDP_TEST was
9874 (SCM): Now defined as typedef struct scm_unused_struct * SCM;
9875 If this appears to be not ANSI compliant, we will change it to
9876 typedef struct scm_unused_struct { } * SCM;
9877 Thanks to Han-Wen Nienhuys for the suggestion.
9879 * unif.c (scm_array_set_x): Fix typing problem, and use

9891 * hooks.c (scm_create_hook): call `scm_gc_protect_object' instead
9892 `scm_protect_object'. shouldn't call it at all, though, it seems.

9928 Changed use of scm_array->scm_array_t and
9929 scm_array_dim->scm_array_dim_t to enable build with
9930 --disable-deprecated.
9932 2001-05-24 Michael Livshin <mlivshin@bigfoot.com>
9934 The purpose of this set of changes is to regularize Guile's usage
9935 of ANSI C integral types, with the following ideas in mind:
9937 - SCM does not nesessarily have to be long.
9938 - long is not nesessarily enough to store pointers.
9939 - long is not nesessarily the same size as int.
9941 The changes are incomplete and possibly buggy. Please test on

10116 (ifdef spaghetti): include sys/types.h and sys/stdtypes.h, if they

10166 New functions. They replace scm_make_gsubr and
10167 scm_make_gsubr_with_generic. The `make' variants only create the
10168 gsubr object, while the `define' variants also put it into the
10169 current module. Changed all callers.
10170 (scm_make_gsubr, scm_make_gsubr_with_generic): Deprecated.
10172 * procs.h, procs.c (scm_c_make_subr, scm_c_define_subr,

10175 scm_make_subr_with_generic. The `make' variants only create the
10176 subr object, while the `define' variants also put it into the
10177 current module. Changed all callers.
10178 (scm_make_subr, scm_make_subr_opt, scm_make_subr_with_generic):
10181 * eval.c, gc.c, gh_funcs.c, goops.c, macros.c, pairs.c, ramap.c,

10887 * socket.c (scm_fill_sockaddr): improve the argument validation.
10888 don't allocate memory until all args are checked. instead of

10919 (SCM_DEFER_INTS, SCM_ALLOW_INTS_ONLY, SCM_ALLOW_INTS,
10920 SCM_REDEFER_INTS, SCM_REALLOW_INTS): Don't use

10924 SCM_THREAD_SWITCHING_CODE.
10925 (SCM_TICK): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS. Instead, use
10926 SCM_THREAD_SWITCHING_CODE directly.
10927 (SCM_ENTER_A_SECTION): Unconditionally use
10928 SCM_CRITICAL_SECTION_START/END. (was:
10929 SCM_DEFER_INTS/SCM_ALLOW_INTS when SCM_POSIX_THREADS defined).
10931 2001-04-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
10933 * __scm.h (SCM_CAREFUL_INTS, SCM_DEBUG_INTERRUPTS): Replaced the
10934 macro SCM_CAREFUL_INTS by the macro SCM_DEBUG_INTERRUPTS and

10956 * init.c, goops.c, goops.h: Reverted change of 2001-03-29. (The
10957 goops module should be registered in order to work for an
10958 application which uses libguile statically linked.)

11087 * gc.c (scm_set_debug_cell_accesses_x):

11100 (scm_string_fill_x): Removed `(r5rs)' from docstrings.
11102 2001-04-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
11104 * gc.c (MARK): Re-introduce a cheap sanity test for non debug
11105 mode, as suggested by Michael Livshin.
11107 2001-03-31 Michael Livshin <mlivshin@bigfoot.com>
11109 * backtrace.c (display_backtrace_body): since the `print_state'
11110 variable is not used (instead its data field is used directly as
11111 `pstate'), protect it from the hungry compiler optimizations.
11112 thanks to Bill Schottstaedt for the report.
11114 2001-03-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
11116 * gc.[ch] (scm_tc16_allocated): New type tag for allocated cells.
11117 It is only defined and used if guile is compiled with
11118 SCM_DEBUG_CELL_ACCESSES set to true. It's purpose is, to never
11119 let cells with a free_cell type tag be visible outside of the
11120 garbage collector when in debug mode.
11122 * gc.c (scm_debug_cell_accesses_p): Set to true as default.
11124 (scm_assert_cell_valid): Use a local static variable to avoid
11127 (MARK): Only check for rogue cell pointers in debug mode. Use
11128 scm_cellp for this purpose and place all checks for rogue pointers
11129 into that function. Further, since due to conservative scanning
11130 we may encounter free cells during marking, don't use the standard
11131 cell type accessor macro to determine the cell type.
11133 (scm_cellp): Check if the cell pointer actually points into a
11136 (scm_init_gc): Initalize scm_tc16_allocated.
11138 * gc.h (GCH): Renamed to SCM_GC_H.
11140 (SCM_VALIDATE_CELL): Enclose the expression in brackets. This
11141 might be unnecessary, but I feel better this way :-)
11143 (SCM_GC_CELL_TYPE): New macro.
11145 (SCM_SETAND_CDR, SCM_SETOR_CDR): Deprecated. These are not used
11146 in guile, and it is unlikely that they will be applied to real
11149 (SCM_SET_FREE_CELL_TYPE): Removed. It was not used.
11151 (SCM_GC_SET_ALLOCATED): New macro. Only non-empty if guile is
11152 compiled with SCM_DEBUG_CELL_ACCESSES set to true.
11154 (SCM_NEWCELL, SCM_NEWCELL2): Use of SCM_GC_SET_ALLOCATED will
11155 make sure that in debug mode no free cell will ever be visible
11156 outside of the garbage collector.
11158 2001-03-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
11160 * async.c (scm_asyncs_pending): Don't use != to compare SCM
11163 * async.c (scm_system_async), variable.c (scm_make_variable,
11164 scm_make_undefined_variable): Use scm_cons to create a pair.
11166 * debug.c (scm_reverse_lookup): Perform proper type checking.
11167 Remove suspicious use of SCM_SLOPPY_CONSP.
11169 * eq.c (scm_equal_p), tags.h (SCM_ECONSP): Use SCM_CONSP instead
11170 of SCM_SLOPPY_CONSP. A sane compiler should be able to perform
11171 the corresponding optimization.
11173 * eval.c (iqq): Use proper type check.
11175 (scm_m_expand_body): Remove redundant type checks.
11177 (promise_print): Don't access promise cells as pairs.
11179 * eval.c (EVALCAR, iqq, scm_m_expand_body, scm_eval_args,
11180 scm_deval_args SCM_CEVAL), guardians.c (scm_guard), hashtab.c
11181 (scm_internal_hash_fold), print.c (scm_iprlist): Use !SCM_CELLP
11182 for SCM_NCELLP, !SCM_CONSP for SCM_NCONSP, !SCM_IMP for SCM_NIMP,
11183 !SCM_FALSEP for SCM_NFALSEP, !SCM_NULLP for SCM_NNULLP
11185 * eval.c (scm_m_define, scm_macroexp, SCM_CEVAL), print.c
11186 (scm_iprin1): Use new macro predicate and accessors.
11188 * eval.h (scm_tc16_macro): Removed declaration. It is declared
11191 * eval.h (EVALH), macros.h (MACROSH), ports.h (PORTSH), procs.h
11192 (PROCSH), tags.h (TAGSH), variable.h (VARIABLEH): Renamed to
11193 SCM_EVAL_H, SCM_MACROS_H, SCM_PORTS_H, SCM_PROCS_H, SCM_TAGS_H and
11194 SCM_VARIABLE_H. Even the macros that are used to inhibit
11195 including a header file twice should be in the SCM_ namespace.
11197 * fluids.c (scm_swap_fluids, scm_swap_fluids_reverse),
11198 properties.c (scm_primitive_property_ref,
11199 scm_primitive_property_del_x): Prefer stronger predicates like
11200 SCM_NULLP or SCM_FALSEP over SCM_IMP.
11202 * gc.c (MARK): Use proper macros to access procedure-with-setter
11203 cell elements and closure cell elements.

11651 * net_db.c (scm_getserv, scm_getproto, scm_getnet): Return #f if
11652 the underlying functions getservent, getprotoent or getnetent
11653 return NULL instead of signalling an error.
11655 2001-03-04 Gary Houston <ghouston@arglist.com>
11657 * socket.c (scm_fill_sockaddr): don't allow buffer overflows when
11658 taking an unexpectedly large filename for an AF_UNIX socket from
11659 bind/connect/sendto (thanks to Martin Grabmueller).
11661 * socket.c (scm_sock_fd_to_port, SCM_SOCK_FD_TO_PORT): removed the
11662 former and adjusted the latter.
11663 (scm_socket, scm_socketpair): cosmetic changes.
11664 (scm_getsockopt, scm_setsockopt): declare optlen as int, not
11665 size_t as socklen_t substitute. don't restrict args/return values
11666 to INUM: allow full range of int or size_t.
11667 (scm_fill_sockaddr): check arguments before allocating memory, to
11668 avoid leakage. use malloc, not scm_must_malloc.
11669 (scm_connect, scm_bind, scm_sendto): use int, not size_t as socklen_t
11670 substitute. free the sockaddr structure before throwing an error.
11671 (scm_init_add_buffer): procedure removed, together with its static
11672 buffer scm_addr_buffer, which wouldn't be thread safe. instead,
11673 define a macro MAX_ADDR_SIZE and declare the buffer where needed.
11674 (scm_accept, scm_getpeername, scm_getsockname, scm_recvfrom,
11675 scm_sendto): use a local buffer instead of scm_addr_buffer.
11676 adjust for new SCM_SOCK_FD_TO_PORT. use int for address size,
11678 (scm_recvfrom): set addr->sa_family to AF_UNSPEC before the recvfrom
11679 call to detect whether recvfrom could be bothered to set the address.
11680 (scm_init_socket): don't call scm_init_addr_buffer.
11682 2001-03-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
11684 * debug.c (scm_procedure_source, scm_procedure_environment),
11685 print.c (scm_get_print_state), ramap.c (scm_array_fill_int,
11686 scm_array_index_map_x), sort.c (scm_sort_x, scm_sort,

11690 scm_transpose_array, scm_enclose_array, scm_array_in_bounds_p,
11691 scm_uniform_vector_ref, scm_array_set_x, scm_uniform_array_read_x,
11692 scm_uniform_array_write, scm_bit_set_star_x, scm_bit_count_star,
11693 scm_array_to_list, scm_array_prototype), validate.h
11694 (SCM_VALIDATE_NUMBER_COPY): Don't call function scm_wta, call
11695 scm_misc_error or scm_wrong_type_arg instead.
11697 * validate.h (SCM_WTA, RETURN_SCM_WTA): Deprecated.
11699 2001-03-04 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
11701 * goops.c, goops.h (scm_sys_pre_expand_closure_x): Removed.
11702 (scm_sys_tag_body): Added.
11704 2001-03-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
11706 * continuations.c (continuation_apply), eval.c (scm_m_lambda,
11707 scm_m_letstar, scm_m_letrec1, scm_m_let, SCM_APPLY), eval.h
11708 (SCM_EVALIM2), evalext.c (scm_m_generalized_set_x), gc.c

11711 ramap.c (scm_ramapc), read.c (skip_scsh_block_comment, scm_lreadr,
11712 scm_lreadparen, scm_lreadrecparen), script.c (script_get_octal,
11713 script_get_backslash, script_read_arg), unif.c (scm_cvref): Don't
11714 call function scm_wta, call scm_misc_error or scm_wrong_type_arg
11717 2001-03-04 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
11719 * goops.c (scm_sys_pre_expand_closure_x): New procedure.
11721 2001-03-04 Marius Vollmer <mvo@zagadka.ping.de>
11723 * eval.c (scm_s_duplicate_bindings): New error message.

11726 2001-03-03 Marius Vollmer <mvo@zagadka.ping.de>
11728 * eval.h (SCM_EVALIM2): New macro. Use it when a
11729 immediate, literal constant should be evaluated.
11730 * eval.c (scm_s_duplicate_formals): New error message string.
11731 (scm_c_improper_memq): New function.
11732 (scm_m_lambda): Check for duplicate arguments.
11733 (scm_ceval, scm_deval): When executing a body: only cons a new
11734 toplevel environment frame when it is different from the
11735 existing one; use EVALCAR instead of SIDEVAL so that we can properly
11736 check for empty combinations; use SCM_EVALIM2 for the same reason
11737 in the non-toplevel loop.
11738 (nontoplevel_cdrxnoap, nontoplevel_cdrxbegin, nontoplevel_begin):
11739 New labels with the meaning of their non-"nontoplevel" partners,
11740 but they are used when it is known that the body is not evaluated at
11742 (scm_apply, scm_dapply): use SCM_EVALIM2 to get proper error
11743 reporting for empty combinations.
11745 2001-03-02 Keisuke Nishida <kxn30@po.cwru.edu>
11747 * Remove dump facilities.

11768 (scm_string_ci_geq_p), symbols.c (scm_symbol_p)
11769 (scm_symbol_to_string, scm_string_to_symbol): Changed use of @t{}
11770 to @code{} as the texinfo manual recommends, converted the
11771 examples to use a @lisp{}-environment.
11773 * strports.c (scm_eval_string): Cleaned up the docstring.
11775 * struct.c (scm_struct_p, scm_struct_vtable_p): Added texinfo

11789 (scm_atanh, scm_truncate, scm_round, scm_exact_to_inexact)
11790 (floor, ceiling, $sqrt, $abs, $exp, $log, $sin, $cos, $tan, $asin)
11791 ($acos, $atan, $sinh, $cosh, $tanh, scm_real_part, scm_imag_part)
11792 (scm_magnitude, scm_angle, scm_abs, scm_quotient, scm_remainder)
11793 (scm_modulo, scm_gcd, scm_lcm): Added (future docstring) comments.
11795 2001-02-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
11797 * __scm.h (SCM_ASSERT_TYPE): Add missing macro parameter.
11798 (Obviously nobody compiles with SCM_RECKLESS defined...)
11800 * validate.h (SCM_ASSERT_RANGE): Use the argument number.
11802 2001-02-23 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
11804 * ports.c, ports.h (scm_c_read, scm_c_write): New functions.
11806 * ports.h (SCM_READ_BUFFER_EMPTY_P): New macro.
11808 2001-02-24 Neil Jerram <neil@ossau.uklinux.net>
11810 * numbers.c (scm_two_doubles, scm_sys_expt, scm_sys_atan2,
11811 scm_make_polar): Rename arguments `z1' and `z2' to `x' and `y',
11812 since use of `z' suggests that the arguments may be complex.
11814 * goops.c (scm_make), numbers.c (scm_sys_expt): Fix docstring
11817 2001-02-23 Neil Jerram <neil@ossau.uklinux.net>

11828 * goops.c (scm_add_method, DEFVAR): Use scm_eval instead of
11830 (make_class_from_template): Do not bother to set the current
11831 module around the call to DEFVAR, scm_eval takes care of that.
11832 (scm_init_goops): Make scm_module_goops and
11833 scm_goops_lookup_closure permanent objects.
11835 * eval.c (scm_ceval, scm_deval): When evaluating expressions on
11836 top level, create a fresh top-level environment for each
11837 expression instead of mutating the exisint frame. This is
11838 important when that frame is closed over.
11840 * numbers.c (s_scm_logior) [SCM_DIGSTOOBIG]: Also use
11841 SCM_DIGSPERLONG instead of DIGSPERLONG.
11843 2001-02-21 Marius Vollmer <mvo@zagadka.ping.de>
11845 * eval.c (scm_ceval, scm_deval): Check for wrong number of args
11846 before applying arrow procedure in `cond' and before applying
11847 receiver procedure in call-with-current-continuation.
11848 (scm_i_eval): Do not invoke scm_copy_tree in argument in SCM_XEVAL
11849 macro. The argument is expanded more than one time.
11851 * numbers.c (scm_logior) [SCM_DIGSTOOBIG]: Correctly use
11852 SCM_BIGDIG instead of BIGDIG. Thanks to Steven G. Johnson!
11854 2001-02-20 Marius Vollmer <mvo@zagadka.ping.de>
11856 * guile-doc-snarf.in, guile-func-name-check.in: Added copyright
11857 notice and license.

11887 (scm_export_environment_set_signature_x, scm_leaf_environment_p):
11888 Added texinfo markup.
11890 * ports.c (scm_drain_input): Lowercased argument to @var.
11891 (scm_current_input_port, scm_current_output_port): Filled in
11892 missing explanation.
11893 (scm_current_load_port, scm_set_current_output_port)

11895 Added texinfo markup.
11897 * arbiters.c (scm_make_arbiter, scm_try_arbiter)
11898 (scm_release_arbiter): Added texinfo markup to docstrings.

11964 2001-02-15 Keisuke Nishida <kxn30@po.cwru.edu>
11966 * dump.c (scm_undump): Use SCM_CARLOC/SCM_CDRLOC to obtain the

11976 2001-02-13 Marius Vollmer <marius.vollmer@uni-dortmund.de>
11978 * gc_os_dep.c: Do not include <linux/version.h>. It makes no
11979 sense to compile for a specific kernel version. Do not include
11980 <asm/signal.h> while defining __KERNEL__. This hack should no
11981 longer be needed and caused problems.
11983 2001-02-13 Marius Vollmer <mvo@zagadka.ping.de>
11985 * eval.c (scm_ceval, scm_deval): use `SIDEVAL' instead of

12003 (scm_i_eval, scm_i_eval_x, scm_eval, scm_eval_x): Changed argument
12004 names to better reflect their meaning.
12006 * eval.c (scm_ceval, scm_deval): Recognize when `begin' is being
12007 evaluated at top-level and synronize lookup closure before
12008 executing every subform.
12009 (scm_primitve_eval_x, scm_primitive_eval): New functions.
12010 (scm_eval_x, scm_eval): Reimplement in terms of
12011 scm_primitive_eval_x and scm_primitive_eval, respectively.
12013 2001-02-09 Marius Vollmer <mvo@zagadka.ping.de>
12015 * macros.c (scm_macro_name, scm_macro_transformer): Use

12019 2001-02-10 Keisuke Nishida <kxn30@po.cwru.edu>
12021 * dump.c (scm_store_bytes): Store data size before data.
12022 (scm_restore_bytes): Restore data size. Takes a pointer to size.
12023 * dump.h (scm_restore_bytes): Updated.
12025 2001-02-09 Keisuke Nishida <kxn30@po.cwru.edu>

12042 before iterating over it. The table might change while the user
12043 code is running. With the snapshot, the user can depend on the
