3 * deprecated.h, deprecated.c, numbers.h (SCM_INUMP, SCM_NINUMP,
4 SCM_INUM): Deprecated by reenaming them to SCM_I_INUMP,
5 SCM_I_NINUMP and SCM_I_INUM, respectively and adding deprecated
6 versions to deprecated.h and deprecated.c. Changed all uses to
7 either use the SCM_I_ variants or scm_is_*, scm_to_*, or
8 scm_from_*, as appropriate.
10 * dynwind.c (scm_i_dowinds): Removed unused code that would call
11 the unexisting scm_cross_dynwind_binding_scope for inums on the
14 2004-07-10 Marius Vollmer <marius.vollmer@uni-dortmund.de>
16 * socket.c (ipv6_net_to_num, scm_from_ipv6): Renamed
17 ipv6_net_to_num to scm_from_ipv6, for converting from an IPv6
18 byte-wise address to a SCM integer. Changed all uses.
19 (ipv6_num_to_net, scm_to_ipv6): Renamed ipv6_num_to_net to
20 scm_to_ipv6 and added type and range checking, for converting from
21 an IPv& byte-wise address to a SCM integer. Changed all uses.
22 (bignum_in_ipv6_range_p, VALIDATE_INET6): Removed, their function
23 is now done by scm_to_ipv6.
25 * numbers.c (scm_to_signed_integer, scm_to_unsigned_integer): dot
26 not accept inexact integers.
28 * validate.h, deprecated.h (SCM_VALIDATE_INUM,
29 SCM_VALIDATE_INUM_COPY, SCM_VALIDATE_BIGINT,
30 SCM_VALIDATE_INUM_MIN, SCM_VALIDATE_INUM_MIN_COPY,
31 SCM_VALIDATE_INUM_MIN_DEF_COPY,SCM_VALIDATE_INUM_DEF,
32 SCM_VALIDATE_INUM_DEF_COPY, SCM_VALIDATE_INUM_RANGE,
33 SCM_VALIDATE_INUM_RANGE_COPY): Deprecated because they make the
34 fixnum/bignum distinction visible. Changed all uses to
35 scm_to_size_t or similar.
37 2004-07-09 Marius Vollmer <marius.vollmer@uni-dortmund.de>
39 * cpp_cnvt.awk: Use scm_from_int instead of SCM_MAKINUM.
41 2004-07-10 Kevin Ryde <user42@zip.com.au>
43 * hash.c (scm_hashq, scm_hashv, scm_hash): Restrict to size>=1 rather
44 than size>=0, since 0<=hash<size cannot be satisfied for size==0, and
45 such a size causes divide-by-zeros in scm_hasher.
47 * regex-posix.c (scm_make_regexp): Free rx on error, to avoid memory
50 2004-07-08 Marius Vollmer <marius.vollmer@uni-dortmund.de>
52 * numbers.c (scm_is_signed_integer, scm_is_unsigned_integer):
53 Rewritten using the same logic as scm_to_signed_integer and
54 scm_to_unsigned_integer, respectively, which is better(tm). Also,
55 use CHAR_BIT instead of hardcoding 8.
56 (LLONG_MIN, LLONG_MAX, ULLONG_MAX): Removed and used
57 SCM_I_LLONG_MIN etc. instead.
59 * numbers.h (SCM_MAKINUM, SCM_I_MAKINUM): Renamed SCM_MAKINUM to
60 SCM_I_MAKINUM and changed all uses.
61 * deprecated.h, deprecated.c (SCM_MAKINUM): Newly deprecated.
63 * gen-scmconfig.c (SCM_I_LLONG_MIN, SCM_I_LLONG_MAX,
64 SCM_I_ULLONG_MAX): Instead of hard-coding the numbers, compute
65 them by assuming twos-complement.
67 2004-07-07 Marius Vollmer <marius.vollmer@uni-dortmund.de>
69 * gen-scmconfig.h.in: Added all the new SCM_I_GSC_*_LIMITS that
70 configure now produces.
71 * gen-scmconfig.c: Use them to output SCM_T_INT8_MIN, etc
72 definitions, giving the limits of the integer types defined by
73 Guile. Also, output a hard coded SCM_I_LLONG_MIN, etc since
74 LLONG_MIN or LONG_LONG_MIN is hard to get at.
76 * numbers.h (scm_to_short, scm_to_ushort): It's SHRT_MIN, etc, not
78 (scm_to_size_t): Use SIZE_MAX instead of cooking our own.
79 (scm_to_long_long, scm_to_ulong_long, scm_to_int8, scm_to_uint8,
80 scm_to_int16, scm_to_uint16, scm_to_int32, scm_to_uint32,
81 scm_to_int64, scm_to_uint64, scm_to_intmax, scm_to_uintmax,
82 scm_from_long_long, scm_from_ulong_long, scm_from_int8,
83 scm_from_uint8, scm_from_int16, scm_from_uint16, scm_from_int32,
84 scm_from_uint32, scm_from_int64, scm_from_uint64, scm_from_intmax,
85 scm_from_uintmax): New.
87 2004-07-06 Marius Vollmer <marius.vollmer@uni-dortmund.de>
89 * tags.h (scm_is_eq): New.
91 * deprecated.h, boolean.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOL,
92 SCM_NEGATE_BOOL, SCM_BOOLP): Deprecated by moving into
93 "deprecated.h". Replaced all uses with scm_is_false, scm_is_true,
94 scm_from_bool, and scm_is_bool, respectively.
96 * boolean.h (scm_is_bool): Fix bug in prototype.
97 (scm_from_bool): The argument is "x" not "f", stupid.
99 * boolean.c (scm_is_bool): Fix typo.
101 * numbers.h, numbers.c (scm_is_integer, scm_is_signed_integer,
102 scm_is_unsigned_integer, scm_to_signed_integer,
103 scm_to_unsigned_integer, scm_to_schar, scm_to_uchar, scm_to_char,
104 scm_to_short, scm_to_ushort, scm_to_long, scm_to_ulong,
105 scm_to_size_t, scm_to_ssize_t, scm_from_schar, scm_from_uchar,
106 scm_from_char, scm_from_short, scm_from_ushort, scm_from_int,
107 scm_from_uint, scm_from_long, scm_from_ulong, scm_from_size_t,
108 scm_from_ssize_t, scm_is_real, scm_to_double, scm_from_double):
111 2004-07-05 Marius Vollmer <marius.vollmer@uni-dortmund.de>
113 * boolean.h, boolean.c (scm_is_true, scm_is_false, scm_from_bool,
116 2004-06-27 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
118 * backtrace.c (display_expression, display_frame): Call
119 scm_i_unmemoize_expr for unmemoizing a memoized object holding a
120 single memoized expression.
122 * debug.c (memoized_print): Don't try to unmemoize the memoized
123 object, since we can't know whether it holds a single expression
126 (scm_mem_to_proc): Removed check for lambda expression, since it
127 was moot anyway. Whoever uses these functions for debugging
128 purposes should know what they do: Creating invalid memoized code
129 will cause crashes, independent of whether this check is present
132 (scm_proc_to_mem): Take the closure's code as it is and don't
133 append a SCM_IM_LAMBDA isym. To allow easier debugging, the
134 memoized code should not be modified.
136 * debug.[ch] (scm_unmemoize, scm_i_unmemoize_expr): Removed
137 scm_unmemoize from public use, but made scm_i_unmemoize_expr
138 available as a guile internal function instead. However,
139 scm_i_unmemoize_expr will only work on memoized objects that hold
140 a single memoized expression. It won't work with bodies.
142 * debug.c (scm_procedure_source), macros.c (macro_print), print.c
143 (scm_iprin1): Call scm_i_unmemocopy_body for unmemoizing a body,
144 i. e. a list of expressions.
146 * eval.c (unmemoize_exprs): Drop internal body markers from the
147 output during unmemoization.
149 * eval.[ch] (scm_unmemocopy, scm_i_unmemocopy_expr,
150 scm_i_unmemocopy_body): Removed scm_unmemocopy from public use,
151 but made scm_i_unmemocopy_expr and scm_i_unmemocopy_body available
152 as guile internal functions instead. scm_i_unmemoize_expr will
153 only work on a single memoized expression, while
154 scm_i_unmemocopy_body will only work on bodies.
156 2004-06-21 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
158 * eval.c (unmemoize_exprs): Handle semi-memoized code.
160 (scm_cons_source, scm_primitive_eval): Prefer higher level
161 predicate SCM_FALSEP over SCM_IMP.
163 2004-06-15 Rob Browning <rlb@defaultvalue.org>
165 * script.c (scm_shell_usage): minor phrasing change.
167 * gc_os_dep.c: update ifdefery for macosx.
168 (scm_get_stack_base): separate result initialization from
169 declaration to slience warnings with macosx and hp-ux using gcc
170 3.3. Thanks to Andreas Vögele.
172 2004-06-13 Han-Wen Nienhuys <hanwen@xs4all.nl>
174 * eval.c (unmemoize_exprs): use SCM_CONSP for the loop condition.
176 2004-06-06 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
178 * list.[ch] (scm_i_finite_list_copy): New internal function to
179 copy lists that are known to be finite (though not necessarily
182 * debug.c (scm_procedure_source): Don't have scm_unmemocopy treat
183 a closure's argument list like an expression of a body.
185 * eval.c (unmemoize_expression, unmemoize_exprs, unmemoize_and,
186 unmemoize_begin, unmemoize_case, unmemoize_cond, unmemoize_delay,
187 unmemoize_do, unmemoize_if, unmemoize_lambda, unmemoize_let,
188 unmemoize_letrec, unmemoize_letstar, unmemoize_or,
189 unmemoize_set_x, unmemoize_apply, unmemoize_atcall_cc,
190 unmemoize_at_call_with_values, unmemoize_future, sym_atslot_ref,
191 unmemoize_atslot_ref, sym_atslot_set_x, unmemoize_atslot_set_x,
192 unmemoize_builtin_macro): New static functions and symbols.
194 (scm_unmemocopy): Rewritten in terms of the above. scm_unmemocopy
195 now has a slightly different meaning: The memoized form that is
196 receives as its argument is now interpreted as a sequence of
197 expressions from a body.
199 (unmemocar, scm_unmemocar): Since the whole functionality of
200 unmemocar and scm_unmemocar is not needed any more, scm_unmemocar
201 has its old content back and is deprecated, while unmemocar has
206 (CEVAL): For unmemoizing a single expression, call
207 unmemoize_expression instead of scm_unmemocopy, which now expects
208 a sequence of body expressions. Eliminated unnecessary empty
209 environment frame when executing let* forms. Eliminated
210 unmemoization step from evaluator.
212 2004-06-02 Marius Vollmer <marius.vollmer@uni-dortmund.de>
214 * eval.c (scm_macroexp, macroexp): Renamed scm_macroexp to
215 macroexp and made static. Added new version of scm_macroexp that
216 emits a deprecation warning and then calls macroexp.
217 (scm_m_undefine): Issue deprecation warning.
219 2004-05-30 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
221 * eval.c (lookup_global_symbol, literal_p, try_macro_lookup):
222 Modified to make set! work on symbols that represent syntactic
225 2004-05-26 Han-Wen Nienhuys <hanwen@xs4all.nl>
227 * gc.h (SCM_CELL_OBJECT_LOC): use SCM_GC_CELL_OBJECT to prevent
228 compound expression as lvalue errors.
230 2004-05-24 Marius Vollmer <mvo@zagadka.de>
232 * dynwind.c (winder_mark): Use SCM_PACK to correctly convert the
233 WINDER_DATA to a SCM.
235 2004-05-24 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
237 * goops.c (compute_getters_n_setters, create_standard_classes,
238 scm_add_slot): Compute closures by calling scm_i_eval_x on a
239 lambda expression rather than creating them with scm_closure.
241 2004-05-22 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
243 * eval.c (s_macro_keyword, scm_m_set_x): Remove checking for
244 misplaced syntactic keywords. This will not work unless guile's
245 defmacro feature is deprecated.
247 (scm_m_case): Fixed a bug that caused the list of labels to grow
248 with every case form.
250 2004-05-19 Kevin Ryde <user42@zip.com.au>
252 * numbers.c (scm_round_number): For inum and big, just return x. For
253 real, use scm_round for 2^54-1 etc problems covered there.
255 * numbers.c (trunc): Remove #define to scm_truncate when the C library
256 doesn't provide trunc. This was for when `truncate' was done as a
257 scm_tc7_dsubr, no longer required.
259 * threads.c (scm_threads_mark_stacks) [SCM_STACK_GROWS_UP]: Correction
260 to stack marking call, two parameters and no cast on t->base.
262 2004-05-18 Marius Vollmer <mvo@zagadka.de>
264 * hashtab.c (rehash_after_gc): Bug fix: properly link the
265 processed hashtables back into the weak_hashtables list. Thanks
266 to Bill Schottstaedt!
268 2004-05-16 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
270 * eval.c (unmemoize_quote): New static function.
272 (scm_m_quote, scm_m_atslot_ref, SCM_CEVAL): Changed the byte code
273 representation of 'quote' and '@slot-ref' to an improper list.
274 This reduces execution time, the number of cells used to hold the
275 memoized code, and thus also reduces garbage collection time.
277 (scm_unmemocopy): Use unmemoize_quote for quote expressions.
279 (SCM_CEVAL): Changed macro handling to also work with macros that
280 return improper lists. Added an assertion, that the code returned
281 by a macro transformer will not lead to cycles in the memoized
284 2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
286 No functional change, just rearrangements of functions within the
289 * eval.c (scm_ilookup, scm_unbound_variable_key,
290 error_unbound_variable, scm_lookupcar1, scm_lookupcar): Moved to
291 the definitions used for execution, since that's where they will
294 2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
296 * numbers.h (SCM_SLOPPY_FRACTIONP): Removed. It was not used
297 throughout guile, has not been part of an official release yet,
298 and the concept of sloppy predicates has never been a good idea.
300 (SCM_FRACTION_NUMERATOR, SCM_FRACTION_DENOMINATOR,
301 SCM_FRACTION_SET_NUMERATOR, SCM_FRACTION_SET_DENOMINATOR):
304 2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
306 * throw.c (SETJBJMPBUF, SCM_SETJBDFRAME): Add cast to scm_t_bits
307 to make explicit what happens.
309 2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
311 * dynl.c (SET_DYNL_HANDLE): Add cast to scm_t_bits to make
312 explicit what happens.
314 * guardians.c (TCONC_IN): Use SCM_SET_CELL_OBJECT_x rather than
315 SCM_SET_CELL_WORD_x when writing scheme objets to cell elements.
317 2004-05-11 Marius Vollmer <mvo@zagadka.de>
319 * scmsigs.c (scm_sigaction_for_thread): Validate that the handler
320 is indeed a procedure when it isn't a number.
322 2004-05-10 Marius Vollmer <mvo@zagadka.de>
324 Convert floating point numbers into strings with an arbitrary
325 radix. Thanks to Richard Todd!
327 * numbers.c (FLOBUFLEN): Increase so that radix 2 strings will
330 (scm_dblprec, fx_per_radix, init_dblprec, init_fx_radix,
331 number_chars): New, to support variable radices.
332 (idbl2str): Use above instead of the old base-10 only tables.
333 (iflo2str): Pass on new RADIX argument to idbl2str.
334 (scm_number_to_string): Pass radix to iflo2str.
335 (scm_print_real, scm_print_complex): Explicitly pass radix 10 to
337 (scm_init_numbers): Call init_dblprec and init_fx_radix for all
340 2004-05-10 Kevin Ryde <user42@zip.com.au>
342 * numbers.c (scm_logbit_p): Correction to test above the end of an
343 inum. Reported by Jan Konecny.
345 2004-05-06 Marius Vollmer <marius.vollmer@uni-dortmund.de>
347 * gc.h (scm_t_cell): Fields are now of type SCM instead of
348 scm_t_bits. Updated all users.
349 (SCM_GC_CARD_SIZE_MASK): Use SCM_GC_SIZEOF_CARD instead of
350 duplicating the code.
351 (SCM_CELL_OBJECT_LOC): New.
352 (SCM_CARLOC, SCM_CDRLOC): Use it instead of SCM_CELL_WORD_LOC.
353 (SCM_CELL_WORD_LOC): Moved to "deprecated.h".
355 * smob.h (SCM_SMOB_DATA_2, SCM_SMOB_DATA_3, SCM_SMOB_FLAGS,
356 SCM_SET_SMOB_DATA_2, SCM_SET_SMOB_DATA_3, SCM_SET_SMOB_FLAGS,
357 SCM_SMOB_OBJECT, SCM_SMOB_OBJECT_2, SCM_SMOB_OBJECT_3,
358 SCM_SET_SMOB_OBJECT, SCM_SET_SMOB_OBJECT_2, SCM_SET_SMOB_OBJECT_3,
359 SCM_SMOB_OBJECT_LOC, SCM_SMOB_OBJECT_2_LOC,
360 SCM_SMOB_OBJECT_3_LOC): New.
361 * smob.c (scm_i_set_smob_flags): New function.
363 * dynl.c, dynwind.c, eval.h, fluids.h, futures.h, hashtab.h,
364 hooks.h, keywords.h, macros.h, macros.c, mallocs.c, mallocs.h,
365 random.h, regex-posix.h, root.h, srcprop.h, srcprop.c, threads.h:
366 Use SCM_SMOB_* instead of SCM_CELL_* as appropriate. Use
367 SCM_SMOB_FLAGS and SCM_SET_SMOB_FLAGS instead of accessing the
368 zeroth word directly. Use SCM_SMOB_PREDICATE as appropriate.
370 * numbers.h (SCM_I_BIG_MPZ): Use SCM_CELL_OBJECT_LOC instead of
371 taking the address of SCM_CELL_WORD_1, the latter being no longer
374 * variable.h (SCM_VARIABLE_LOC): Use SCM_CELL_OBJECT_LOC instead
375 of casting SCM_CELL_WORD_LOC.
377 2004-05-02 Kevin Ryde <user42@zip.com.au>
379 * eval.c (scm_macroexp): Add prototype, since it's not in eval.h under
380 --disable-deprecated. Reported by Andreas Vögele.
382 * filesys.c (_POSIX_C_SOURCE): Define to 199506L to get readdir_r (in
383 particular on HP-UX). Reported by Andreas Vögele.
385 * list.c (varargs.h): Remove, leave just stdarg.h which is all the
386 code has support for. Fixes building with AIX cc, which is ansi but
387 doesn't define __STDC__. Reported by Keith Crane.
388 (var_start): Remove macro, this variation no longer required.
389 (scm_list_n): Use va_start directly.
391 2004-05-01 Kevin Ryde <user42@zip.com.au>
393 * continuations.c (scm_dynthrow): Use >= instead of SCM_PTR_GE which
394 is now gone. Reported by Andreas Vögele.
396 2004-04-28 Kevin Ryde <user42@zip.com.au>
398 * backtrace.c (display_frame_expr), numbers.c (XDIGIT2UINT,
399 mem2uinteger, mem2decimal_from_point, mem2ureal): Cast char to int for
400 ctype.h tests, to avoid warnings from gcc on HP-UX about char as array
401 subscript. Reported by Andreas Vögele.
402 Also cast through unsigned char to avoid passing negatives to those
403 macros if input contains 8-bit values.
405 * num2integral.i.c (NUM2INTEGRAL): Under non-BIGMPZ_FITSP case,
406 corrections to range check for signed numbers. Remove
407 scm_remember_upto_here_1(num) from these checks, since num is used
410 * num2integral.i.c (NUM2INTEGRAL): Test BIGMPZ_FITSP with "!= 0" to
411 avoid warning from gcc 3.4. Reported by Hyperdivision.
413 * numbers.c (scm_bit_extract): Use min instead of MIN.
414 (MIN): Remove, this conflicts with similar macro defined by limits.h
415 on HP-UX. Reported by Andreas Vögele.
417 * stime.c (_POSIX_C_SOURCE): Define to 199506L to get gmtime_r (in
418 particular on HP-UX). Reported by Andreas Vögele.
420 * threads.c (scm_threads_mark_stacks): Correction sizet -> size_t.
421 Reported by Andreas Vögele.
423 * threads-plugin.h (SCM_MUTEX_MAXSIZE): Increase to 25*sizeof(long),
424 for the benefit of hpux11 where pthread_mutex_t is 88 bytes. Reported
427 2004-04-22 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
429 * eval.c (s_macro_keyword): New static identifier.
431 (scm_m_define): Change order to first create binding and
432 evaluating the expression afterwards.
434 (scm_m_set_x): Memoize complete set! expression. Only leave
435 symbols if no binding exists at memoization time. Throw error if
436 assigning to a syntactic keyword.
438 (lazy_memoize_variable): New function.
440 (CEVAL): When execution set!, perform lazy memoization if
441 unmemoized symbol is detected.
443 * modules.c (module_variable): Return variables with unbound
446 * tags.h: Fix comment.
448 2004-04-25 Kevin Ryde <user42@zip.com.au>
450 * chars.c (scm_char_upcase, scm_char_downcase, scm_c_upcase,
451 scm_c_downcase): Use ctype.h toupper and tolower. This will be useful
452 in 8-bit locales, and ensures consistency with char-upper-case? and
453 char-lower-case? which already use ctype.h.
454 (scm_c_upcase_table, scm_c_downcase_table, scm_lowers, scm_uppers):
456 * chars.c, chars.h, init.c (scm_tables_prehistory): Remove.
458 * socket.c (VALIDATE_INET6): Correction to bignum_in_ipv6_range_p
459 call. Reported by Hyperdivision.
461 * threads.c (scm_yield): Correction, actually call scm_thread_yield.
462 Reported by Hyperdivision.
464 * unif.c (s_scm_make_uve): Remove unused local variable. Reported by
467 2004-04-22 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
469 Hide the implementation of ilocs and isyms in eval.c.
471 * deprecated.h (SCM_IFRINC, SCM_ICDR, SCM_IFRAME, SCM_IDIST,
472 SCM_ICDRP), eval.c (SCM_IFRINC, SCM_ICDR, SCM_IFRAME, SCM_IDIST,
473 SCM_ICDRP), eval.h (SCM_ICDR, SCM_IFRINC, SCM_IFRAME, SCM_IDIST,
474 SCM_ICDRP): Deprecated and added to deprecated.h. Moved from
477 * deprecated.c (scm_isymnames), deprecated.h (scm_isymnames,
478 SCM_ISYMNUM, SCM_ISYMCHARS), eval.c (SCM_ISYMNUM, isymnames,
479 scm_unmemocopy, CEVAL), print.c (scm_isymnames), tags.h
480 (SCM_ISYMNUM, scm_isymnames, SCM_ISYMCHARS): Deprecated
481 scm_isymnames, SCM_ISYMNUM and SCM_ISYMCHARS and added to
482 deprecated.[hc]. Moved scm_isymnames from print.c to eval.c and
483 renamed to isymnames. Moved SCM_ISYMNUM from tags.h to eval.c and
486 * eval.c (scm_i_print_iloc, scm_i_print_isym), eval.h
487 (scm_i_print_iloc, scm_i_print_isym), print.c (scm_iprin1):
488 Extracted printing of ilocs and isyms to guile internal functions
489 scm_i_print_iloc, scm_i_print_isym of eval.c.

493 * numbers.c (scm_bit_extract): Use SCM_SRS for signed right shift.
495 * numbers.c (scm_round): Test for x already an integer, to avoid bad
496 rounding in x+0.5 when x is a big value already an integer. In
497 certain hardware rounding cases x+0.5 can give an adjacent integer,
498 leading to that as the result, when we really just wanted x itself.
500 2004-04-19 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
502 * eval.c (scm_unmemocopy): Fixed unmemoization of let*.
504 (deval_args, CEVAL): Minor improvements: Reduced variable scopes,
505 added const qualifiers, cast intentionally unused expressions to
506 void for emphasis, improved comment.
508 2004-04-18 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
510 * tags.h (scm_tags, scm_tc8_tags, scm_tc9_flag, scm_tc8_flag,
511 scm_tc8_isym): Renamed scm_tags to scm_tc8_tags. Renamed
512 scm_tc9_flag to scm_tc8_flag. Introduced new identifier
513 scm_tc8_isym. Defined tc8-tags relative to scm_tc3_imm24.
514 Defined the tc8-tag for flags to be 0x04, which will mean that
515 SCM_BOOL_F will also have the value 0x04 instead of 0x013c. Due
516 to the reduced number of bits and the simpler bit pattern for
517 SCM_BOOL_F, certain machines may be able to use more efficient
518 processor instructions to deal with SCM_BOOL_F.
520 (SCM_ITAG9, SCM_MAKE_ITAG9, SCM_ITAG9_DATA): Removed. These have
521 never been defined in a released version, thus no need to
524 (SCM_IFLAGP, SCM_MAKIFLAG, SCM_IFLAGNUM): Flags now use tc8
527 (SCM_ISYMP, SCM_MAKISYM, SCM_ISYMNUM): Isyms now use tc8 instead
530 (SCM_MAKSPCSYM): Removed. It is almost impossible that user code
531 could have used this definition.
533 (SCM_IM_AND, SCM_IM_BEGIN, SCM_IM_CASE, SCM_IM_COND, SCM_IM_DO,
534 SCM_IM_IF, SCM_IM_LAMBDA, SCM_IM_LET, SCM_IM_LETSTAR,
535 SCM_IM_LETREC, SCM_IM_OR, SCM_IM_QUOTE, SCM_IM_SET_X): Now encoded
536 as isyms, as special isyms don't exist any more.
538 2004-04-18 Kevin Ryde <user42@zip.com.au>
540 * filesys.c (scm_readdir): Use readdir_r when available, for thread
543 * numbers.c (scm_max, scm_min): For big/real, use SCM_SWAP rather than
544 explicit swapping code.
546 2004-04-15 Kevin Ryde <user42@zip.com.au>
548 * cpp_sig_symbols.in: Add SIGSYS.
550 * list.c (scm_append_x): Use iterative style, to avoid non-tail
553 * numbers.c (scm_max, scm_min): For inum/frac, frac/inum, big/frac,
554 frac/big and frac/frac, use scm_less_p for exact comparison.
556 * numbers.c (scm_gcd): For inum/big, use mpz_gcd_ui by sharing code
559 * numbers.c (xisinf): Add a comment about solaris 7 lacking isinf.
561 2004-04-06 Han-Wen Nienhuys <hanwen@xs4all.nl>
563 * inline.h (scm_cell): use SCM_GC_CELL_WORD for checking tag.
565 * chars.h (scm_init_chars): change scm_{upcase,downcase} to
567 (SCM_MAKE_CHAR): add (unsigned char) cast. This prevents havoc
568 when hi-bit ASCII is subjected to SCM_MAKE_CHAR().
570 2004-04-06 Kevin Ryde <user42@zip.com.au>
572 * numbers.c (scm_ash): Remove stray "}" in docstring.
574 * numbers.c (scm_make_ratio): For inum/bignum integer detection, use
575 x==SCM_MOST_NEGATIVE_FIXNUM explicitly, for clarity and to avoid
576 calling mpz_cmp_ui in most cases.
578 * numbers.c (scm_quotient, scm_remainder): In inum/big, use mpz_cmp_ui
579 for big == abs(most-negative-fixnum) special case.
580 (abs_most_negative_fixnum): Remove, no longer used.
582 * scmsigs.c (scm_sigaction_for_thread): Correction to signum range
583 test, avoids SCM_VECTOR_REF outside bounds of signal_handlers on
584 calling (sigaction NSIG).
586 * simpos.c (scm_system_star): Fix execargv memory leak, merge parent
587 and fork error cases to do this.
589 2004-04-03 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
591 * eval.c (CEVAL): Don't distinguish between short and long
592 instructions when dispatching - just always dispatch on the
593 instruction code, which is common for short and long instructions.
594 Further, removed unnecessary goto statements and added comment.
596 2004-04-03 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
598 * eval.c (scm_unmemocopy): Don't distinguish between short and
599 long instructions when dispatching - just always dispatch on the
600 instruction code, which is common for short and long instructions.
601 Further, removed unnecessary goto statements, fixed indentation
602 and replaced SCM_IMP predicates by SCM_NULLP.
604 2004-04-03 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
606 * eval.c (scm_lookupcar1, CEVAL): Use SCM_ILOCP instead of
607 comparison with SCM_ILOC00. In CEVAL, eliminate goto-label
610 2004-03-31 Kevin Ryde <user42@zip.com.au>
612 * simpos.c: Include <signal.h> for SIG_IGN and friends.
614 2004-03-29 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
616 Introduce scm_debug_mode_p as a replacement for scm_debug_mode and
619 * debug.h (scm_debug_mode_p, scm_debug_mode, SCM_DEBUGGINGP),
620 eval.c (scm_debug_mode_p): Deprecated scm_debug_mode and
621 SCM_DEBUGGINGP. Provided scm_debug_mode_p instead, to have one
622 single interface that also matches the naming conventions.
623 Probably scm_debug_mode_p should be part of the private interface
626 * debug.h (scm_debug_mode_p), backtrace.c (display_error_body),
627 eval.c (SCM_APPLY, scm_trampoline_0, scm_trampoline_1,
628 scm_trampoline_2): Change uses of scm_debug_mode or SCM_DEBUGGINGP
632 Deprecate direct access to scm_ceval, scm_deval and scm_ceval_ptr:
634 * eval.h (scm_ceval, scm_deval, scm_ceval_ptr), debug.h
635 (scm_ceval_ptr): Deprecated. Moved declaration of scm_ceval_ptr
636 from debug.h to eval.h.
638 * debug.h (SCM_RESET_DEBUG_MODE): Don't access scm_ceval_ptr any
639 more, just leave it with setting scm_debug_mode_p, which is
640 equivalent for practical purposes.
642 * deprecated.h (SCM_XEVAL, SCM_XEVALCAR): Call scm_i_eval_x
643 instead of *scm_ceval_ptr. Leave all evaluating to scm_i_eval_x.
645 * gdbint.c (gdb_eval): Call scm_i_eval_x instead of scm_ceval.
647 * eval.c (ceval, deval, scm_ceval, scm_deval): Made scm_ceval
648 static and renamed it to ceval throughout. Provide a new exported
649 but deprecated function scm_ceval as a wrapper for backwards
650 compatibility. The same is done for the deval/scm_deval pair of
653 * eval.c (CEVAL, SCM_CEVAL): Renamed SCM_CEVAL to CEVAL
654 throughout. Defined CEVAL to ceval or deval, based on compilation
657 * eval.c (SCM_XEVAL, SCM_XEVALCAR): Dispatch on scm_debug_mode_p
658 to ceval and deval instead of calling *scm_ceval_ptr.
660 * eval.c (dispatching_eval): New deprecated static function.
662 * eval.c (scm_ceval_ptr): Initialized to dispatching_eval in order
663 to emulate its old behaviour as closely as possible.
666 Change the evaluator such that only expressions for which pair? is
667 true are passed to CEVAL, and such that all other expressions are
668 evaluated outside of CEVAL:
670 * eval.c (EVAL): New, provided in analogy to EVALCAR. Evaluate an
671 expression that is assumed to be memoized already. All but
672 expressions of the form '(<form> <form> ...)' are evaluated inline
673 without calling an evaluator.
675 * eval.c (SCM_XEVAL, SCM_XEVALCAR, EVALCAR): Evaluate all but
676 expressions of the form '(<form> <form> ...)' inline without
677 calling an evaluator.
679 * eval.c (scm_i_eval_x, scm_i_eval, scm_ceval, scm_deval): Handle
680 the special case of unmemoized symbols passed on the top level.
682 * eval.c (CEVAL): Change calls to CEVAL to EVAL, except where it
683 is known that the expression passed to CEVAL is of the form
684 '(<form> <form> ...)'. Remove handling of the tc7-objects, since
685 now it is known that the input expression of CEVAL is a pair.
687 2004-03-29 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
689 * eval.c (is_self_quoting_p): New static function.
691 (scm_m_quote): Use is_self_quoting_p.
693 (copy_tree): Corrected typo in comment.
695 2004-03-28 Han-Wen Nienhuys <hanwen@xs4all.nl>
697 * eval.c (s_scm_copy_tree): idem.
699 * list.c (s_scm_filter): remove "pointer" from doc string.
701 * gc.h (SCM_GC_CELL_TYPE): SCM_GC_CELL_TYPE uses SCM_GC_CELL_OBJECT.
703 * goops.h (SCM_NUMBER_OF_SLOTS): don't SCM_UNPACK the result.
705 * backtrace.c ("display_backtrace_body"): SCM_PACK before SCM_EQ_P
706 (display_frame): idem.
707 (display_backtrace_file_and_line): idem.
709 * tags.h (SCM_UNPACK): stricter typechecking on SCM_UNPACK
712 2004-03-26 Kevin Ryde <user42@zip.com.au>
714 * filesys.c (scm_getcwd, scm_readlink): Avoid memory leak on errors.
716 * numbers.c (scm_modulo): For inum/big and big/big, remove test of
717 big==0 since that never occurs.
719 * numbers.c, numbers.h (scm_modulo_expt): Renamed from
720 scm_modular_expt, matching scheme level name `modulo-expt'.
722 * numbers.c (scm_modular_expt): Return a negative remainder for a
723 negative divisor, the same as `modulo' does.
725 2004-03-26 Eric Hanchrow <offby1@blarg.net>
727 * numbers.c, numbers.h (scm_modular_expt): New function.
729 2004-03-25 Kevin Ryde <user42@zip.com.au>
731 * numbers.c (scm_min, scm_max): Correction to big/real and real/big,
732 return inexact as required by r5rs.
734 2004-03-24 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
736 * eval.c: Separated some definitions relevant for execution from
737 the memoization part of the file.
739 (copy_tree): New static function
741 (scm_copy_tree): Rewritten to fix two kinds or bugs: First, cyclic
742 structures are detected now and will lead to an exception instead
743 of forcing guile to run in an endless loop, using up all the
744 system's memory. Second, arrays in the cdr of an improper list
745 are now copied. See the new test cases in eval.test.
747 2004-03-24 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
749 * posix.c (scm_gethostname): Make sure len is initialised before
750 it is used. Restructured to (hopefully) represent possible
751 configurations more clearly in the code. Added unwind handler.
753 2004-03-23 Kevin Ryde <user42@zip.com.au>
755 * posix.c (scm_gethostname): Use sysconf(_SC_HOST_NAME_MAX) and/or
756 MAXHOSTNAMELEN when available.
758 2004-03-21 Marius Vollmer <mvo@zagadka.de>
760 * read.c (skip_scsh_block_comment): Also recognize '\r' as a line
761 terminator. Rewritten the logic as a state machine, I must have
762 been doing too much VHDL lately...
764 * eval.c (scm_ceval, scm_deval): Explicitely evaluate ports to
765 themselves. Thanks to Han-Wen Nienhuys!
767 * list.c: Changed docstrings so that they no longer talk about
768 returning 'pointers' to something.
770 2004-03-20 Han-Wen Nienhuys <hanwen@xs4all.nl>
772 * gc.c: remove set_debug_cell_accesses! when
773 SCM_DEBUG_CELL_ACCESSES is not defined. Scheme source code should
774 use (if (defined? 'set-debug-cell-accesses!) .. ) to switch on
775 debugging conditionally.
777 2004-03-21 Kevin Ryde <user42@zip.com.au>
779 * stime.c (scm_gmtime): Use gmtime_r when available, for thread safety.
781 2004-03-20 Kevin Ryde <user42@zip.com.au>
783 * posix.c (scm_gethostname): Preserve errno across free() call.
785 2004-03-18 Han-Wen Nienhuys <hanwen@xs4all.nl>
787 * gc-card.c (sweep_card): use SCM_GC_SET_CELL_WORD for setting
790 2004-03-14 Kevin Ryde <user42@zip.com.au>
792 * stime.c: Define _GNU_SOURCE for strptime prototype from glibc.
793 (strptime): Use HAVE_DECL_STRPTIME for when to give own prototype.
795 2004-03-07 Kevin Ryde <user42@zip.com.au>
797 * stime.c (scm_gmtime): Return bd_time->tm_zone when available, rather
799 (filltime): Make zname parameter "const".
801 2004-03-03 Mikael Djurfeldt <mdj@chunk.mit.edu>
803 * threads.c, threads.h (scm_c_scm2thread): New function.
805 2004-02-29 Kevin Ryde <user42@zip.com.au>
807 * numbers.c (guile_ieee_init): Use C99 INFINITY and NAN when
808 available. Test HAVE_DINFINITY and HAVE_DQNAN for those globals, in
809 particular don't assume "defined (__alpha__) && ! defined (linux)"
810 means OSF. Remove "SCO" code, which was not really SCO specific and
811 which John W. Eaton advises should be long past being needed.
813 * posix.c (scm_execl, scm_execlp, scm_execle): Avoid memory leak under
816 2004-02-24 Kevin Ryde <user42@zip.com.au>
818 * posix.c (scm_cuserid): Use a private result buffer, for thread safe.
820 2004-02-22 Kevin Ryde <user42@zip.com.au>
822 * numbers.c (scm_max, scm_min): For one arg, dispatch to generic for
823 complex, same as for two args. (Handle only inum, big, real, frac).
825 2004-02-21 Kevin Ryde <user42@zip.com.au>
827 * posix.c (scm_crypt): Use new HAVE_CRYPT.
828 (<crypt.h>): Remove HAVE_LIBCRYPT condition.
829 Reported by Andreas Voegele.
831 2004-02-20 Neil Jerram <neil@ossau.uklinux.net>
833 * list.c (scm_list_n): Add #if SCM_DEBUG_CELL_ACCESSES_P around
836 * read.c (scm_lreadparen): Removed.
837 (scm_lreadparen1): Renamed scm_i_lreadparen.
839 2004-02-20 Han-Wen Nienhuys <hanwen@xs4all.nl>
841 * list.c (scm_list_n): validate non-immediate arguments;
842 this will catch forgotten a SCM_UNDEFINED.
844 2004-02-18 Marius Vollmer <mvo@zagadka.de>
846 * gc.h (scm_gc_cells_collected): Removed duplicated declaration.
847 Thanks to Bill Schottstaedt!
849 * socket.h (scm_gethost): Removed prototype it is already in
850 "net_db.h". Thanks to Bill Schottstaedt!
852 2004-02-18 Kevin Ryde <user42@zip.com.au>
854 * num2integral.i.c (INTEGRAL2BIG): WORDS_BIGENDIAN not right for word
855 order parameter to mpz_import, in fact with just one word there's no
856 order to worry about at all.
858 * numbers.c (scm_num_eq_p): For real==frac, complex==frac, frac==real
859 and frac==complex, make an exact comparison rather than converting
860 with fraction2double.
862 * posix.c, putenv.c, stime.c (environ): Use _NSGetEnviron in Darwin
863 shared library, since environ is not directly available there.
865 * script.c (scm_shell_usage): Print to stdout for --help, per GNU
868 * stime.c (scm_localtime, scm_gmtime, scm_mktime): Provide a default
869 errno EINVAL in case localtime and gmtime don't set it.
870 (scm_mktime, scm_strptime): Forcibly use errno EINVAL for our
871 SCM_SYSERROR, since mktime and strptime generally don't set errno.
873 2004-02-16 Kevin Ryde <kevin@swox.se>
875 * gc-malloc.c (scm_done_malloc, scm_done_free): Allow negative sizes,
876 which were permitted in the past for these.
878 * num2float.i.c (NUM2FLOAT): Expand isfinite to !xisinf, as per
879 previous change to numbers.c.
881 * script.c (scm_shell_usage): Print bug-guile email address, as per
882 GNU standard. Reported by Han-Wen Nienhuys.
884 2004-02-13 Mikael Djurfeldt <djurfeldt@nada.kth.se>
886 * unif.c (scm_make_uve): Removed local variable and simplified
887 code in order to avoid compiler used uninitialized warnings.
889 * hashtab.c, hashtab.h (scm_hash_map_to_list): Renamed from
891 (scm_hash_fold): Use scm_call_3 directly in the call to
892 scm_internal_hash_fold instead of going via fold_proc (which is
894 (scm_hash_for_each): Use a trampoline +
895 scm_internal_hash_for_each_handle.
896 (scm_internal_hash_for_each_handle, scm_hash_for_each_handle): New
899 2004-02-12 Kevin Ryde <user42@zip.com.au>
901 * ports.c (scm_port_line): In docstring, note first line is 0.
902 (scm_set_port_line_x): In docstring, note first line is 0.
903 (scm_port_column): In docstring, there's no default to current input
904 port, and remove shared port-line @defun.
905 (scm_set_port_column_x): In docstring, there's no default to current
906 input port, note first column is 0, remove shared set-port-line!
909 * ramap.c (scm_array_fill_x): For fvect and dvect, use scm_num2dbl to
910 convert args the same way that array-set! does.
912 * unif.c (scm_make_uve, scm_array_p): Allow fraction 1/3 as prototype
914 (scm_array_p): Add missing "break"s in switch, fix llvect test look
915 for "l" not "s", fix dvect to be false for singp(prot) since such a
917 (scm_array_prototype): Return 1/3 for dvect, rather than 0.33..33.
918 (exactly_one_third): New variable.
919 (scm_init_unif): Initialize it.
921 2004-02-10 Neil Jerram <neil@ossau.uklinux.net>
923 * read.c (scm_read_opts): Change `escaped-parens' to
926 2004-02-08 Neil Jerram <neil@ossau.uklinux.net>
928 * read.c (scm_read_opts): New opts `elisp-vectors' and
931 (scm_lreadr): Use scm_lreadparen1 instead of scm_lreadparen. Make
932 handling of elisp vector syntax dependent on SCM_ENABLE_ELISP and
933 `elisp-vectors' option instead of SCM_ELISP_READ_EXTENSIONS.
934 Allow "\(" and "\)" in strings when SCM_ENABLE_ELISP defined and
935 `escaped-parens' option set.
936 (scm_read_token): If elisp vector syntax active, disallow [ and ]
938 (scm_lreadparen): Rewrite as interface to scm_lreadparen1.
939 (scm_lreadparen1): New.
941 * read.h: Remove conditionally compiled last arg to
943 (SCM_ELISP_VECTORS_P, SCM_ESCAPED_PARENS_P): New.
945 2004-01-23 Han-Wen Nienhuys <hanwen@xs4all.nl>
947 * eval.c (m_expand_body): remove stray variable new_body.
949 2004-01-22 Marius Vollmer <mvo@zagadka.de>
951 * eval.c (m_expand_body): Rewrite the expression in place (by
952 overwriting FORMS) also when a letrec is constructed, not only
953 when no definitions are found. Do not return rewritten expression
954 to emphasize the in-place rewriting. Changed all users.
956 2004-01-19 Han-Wen Nienhuys <hanwen@xs4all.nl>
958 * gc.c: add protected_object_count, a number that is dumped from
961 2004-01-11 Marius Vollmer <mvo@zagadka.de>
963 * dynwind.h, dynwind.c (scm_frame_unwind,
964 scm_frame_unwind_handler): Renamed and changed all uses.
965 (scm_frame_rewind, scm_frame_rewind_handler): Likewise.
967 2004-01-11 Kevin Ryde <user42@zip.com.au>
969 * unif.c (scm_bit_count, scm_bit_position, s_scm_bit_set_star_x,
970 s_scm_bit_count_star, s_scm_bit_invert_x): Clarify docstrings, as per
971 changes made to scheme-compound.texi.
973 2004-01-10 Marius Vollmer <mvo@zagadka.de>
975 * print.c (scm_print_symbol_name): Handle #{`foo}#, #{,foo}#,
976 #{.}#, and all numeric strings specially. Thanks to Paul Jarc!
978 * guile-snarf.in: Use mkdir to create a unique temporary directory
979 that we can safely use. Thanks to Stefan Nordhausen!
981 2004-01-07 Marius Vollmer <marius.vollmer@uni-dortmund.de>
983 * dynwind.h, dynwind.c (scm_i_dowinds): Removed 'explicit'
984 argument since it is always zero now. Changed all callers.
985 Removed code for handling fluids.
987 * fluids.c (scm_c_with_fluids): Use frames instead of adding to
988 the wind chain explicitely. Use scm_c_with_fluid for the common
989 case of only one fluid.
990 (scm_with_fluid): New.
991 (scm_c_with_fluid): Use frames instead of scm_c_with_fluids.
993 * fluids.h, fluids.c (scm_frame_fluid): New.
994 (scm_with_fluid): New.
995 (scm_i_swap_fluids, scm_i_swap_fluids_reverse): Removed.
997 * dynwind.c (scm_frame_end): Do not use scm_i_dowinds. Instead,
998 do the unwinding directly. It is simple enough.
1000 * dynwind.h, dynwind.c: Did the following renamings:
1001 scm_begin_frame -> scm_frame_begin,
1002 scm_end_frame -> scm_frame_end,

1005 scm_on_unwind_with_scm -> scm_frame_unwind_with_scm,
1006 scm_on_rewind_with_scm -> scm_frame_rewind_with_scm.
1009 * aync.h, async.c: Did the follwing renamings:
1010 scm_with_blocked_asyncs -> scm_frame_block_asyncs,
1011 scm_with_unblocked_asyncs -> scm_frame_unblock_asyncs.
1014 * ports.h, ports.c: Did the follwing renamings:
1015 scm_with_current_input_port -> scm_frame_current_input_port,
1016 scm_with_current_output_port -> scm_frame_current_output_port,
1017 scm_with_current_error_port -> scm_frame_current_error_port.
1020 2004-01-07 Kevin Ryde <user42@zip.com.au>

1037 * fluids.h, fluids.c (scm_make_initial_fluids, scm_copy_fluids,
1038 scm_swap_fluids, scm_swap_fluids_reverse): Renamed to
1039 scm_i_... since they are internal. Changed all uses.
1041 * dynwind.c (frame_print): Removed, use the default printer.
1042 (WINDER_F_MARK, WINDER_MARK_P, winder_mark): New.
1043 (scm_on_unwind_with_scm, scm_on_rewind_with_scm): New. Use above
1044 to protect SCM values.
1046 * dynwind.h (SCM_F_WIND_EXPLICITELY,
1047 SCM_F_WIND_EXPLICITLY): It's "explicitly" not "explicitely", damn.
1049 (scm_on_unwind_with_scm, scm_on_rewind_with_scm): New.
1051 2004-01-05 Marius Vollmer <mvo@zagadka.de>

1062 scm_begin_frame, scm_end_frame, scm_on_unwind, scm_on_rewind):
1064 (scm_dowinds, scm_i_dowinds): scm_dowinds has been renamed to
1065 scm_i_dowinds and extended to handle frames and to invoke a 'turn'
1066 function when the outermost wind point has been reached. The
1067 latter is used to copy a continuation stack at the right time.
1068 scm_dowinds remains available.
1069 (SCM_GUARDSP, SCM_BEFORE_GUARD, SCM_AFTER_GUARD, SCM_GUARD_DATA,
1070 tc16_guard, guards_print): Removed.
1071 (scm_internal_dynamic_wind): Reimplemented using frames.

1074 part of copy_stack_and_call.
1075 (copy_stack_and_call): Copy the stack after unwinding and before
1077 (scm_dynthrow): Do not call scm_dowinds, this is now done by
1078 copy_stack_and_call.
1080 2004-01-04 Kevin Ryde <user42@zip.com.au>
1082 * numbers.c (scm_less_p): Don't convert frac to float for compares,
1083 can give bad results due to rounding.
1085 * stime.c (scm_current_time, scm_gettimeofday): Add a comment about
1086 setzone/restorezone protection for DOS.
1088 2003-12-26 Marius Vollmer <mvo@zagadka.de>

1095 * numbers.c (scm_less_p): Remove spurious xisnan from frac+big case.
1097 * numbers.c (scm_make_ratio): Check for numerator equal to
1098 SCM_MOST_NEGATIVE_FIXNUM and bignum denominator the negative of that,
1101 * numbers.c (scm_real_part): Return fraction unchanged rather than
1102 converting to flonum.
1104 2003-11-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
1106 * modules.c (module_variable): Fixed (and thus simplified) the
1107 definition of SCM_BOUND_THING_P to reflect the fact that since
1108 after the 1.4 series of guile, obarrays only hold variable
1111 2003-11-30 Marius Vollmer <mvo@zagadka.de>
1113 * numbers.c (scm_logand): It's "#b...", not "#\b...".

1130 * eval.c (s_bad_define): New static identifier.
1132 (m_body): Fixed comment.
1134 (scm_m_define): Don't generate memoized code for definitions that
1135 are not on the top level. As a consequence, no memoized code at
1136 all is generated for definitions any more: Top level definitions
1137 are executed immediately during memoization and internal
1138 definitions are handled separately in m_expand_body.
1140 (scm_unmemocopy, unmemocopy): Removed code for unmemoizing
1141 definitions. Consequently, there is no unmemoizing code any more
1142 that might modify the environment. Thus, the old scm_unmemocopy
1143 is removed and the old unmemocopy is renamed to scm_unmemocopy.
1145 (SCM_CEVAL): The SCM_IM_DEFINE keyword can no longer occur in
1146 memoized code. Call EVALCAR for continuations. Prefer !SCM_NULLP
1147 over SCM_NIMP in places, where the argument is known to be part of

1156 to share some shifting.
1158 * numbers.c (scm_integer_expt): Don't mpz_init after scm_i_clonebig or
1159 scm_i_mkbig, since they do so already. Don't mpz_clear a bignum SCM,
1162 2003-11-19 Marius Vollmer <mvo@zagadka.de>
1164 * numbers.c (scm_make_ratio): Rewritten to have a simpler
1165 structure. Previously, not all cases with a negative denominator
1168 * numbers.c (mem2decimal_from_point): use scm_divide instead of
1169 scm_divide2real when forming the fractional part. This allows
1170 "#e1.2" to yield 6/5.
1172 * numbers.c (scm_i_fraction_equalp): Do not treat the return value
1173 of scm_equal_p as a C boolean, use SCM_FALSEP. Previously, all
1174 fractions were equal to each other regardless of value. Ooops.

1223 to doubles when calling 'dsubr' functions.
1225 * eq.c (scm_eqv_p, scm_equal_p): Handle fractions.

1229 * gen-scmconfig.c (main): remove public definition of
1230 SCM_SIZEOF___INT64 and SCM_SIZEOF_UNSIGNED___INT64 and add
1231 direct typedef of long_long and ulong_long inside deprecated block
1234 * deprecated.h: move long_long and ulong_long definitions to
1235 gen-scmconfig.c so that we don't need to add SCM_SIZEOF___INT64
1236 and SCM_SIZEOF_UNSIGNED___INT64 to the public namespace.

1556 syntactic keyword '=>.
1558 2003-10-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
1560 * eval.c (scm_m_case): Allow empty lists of case labels.
1562 2003-10-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
1564 * tags.h (SCM_IM_ELSE, SCM_IM_ARROW): New memoizer codes.
1566 * print.c (scm_isymnames): Add names for the new memoizer codes.
1568 * eval.c (s_missing_clauses, s_bad_case_clause,
1569 s_extra_case_clause, s_bad_case_labels, s_duplicate_case_label,
1570 literal_p): New static identifiers.
1572 (scm_m_case): Use ASSERT_SYNTAX to signal syntax errors. Be more
1573 specific about the kind of error that was detected. Check for
1574 duplicate case labels. Handle bound 'else. Avoid unnecessary
1575 consing when creating the memoized code.
1577 (scm_m_case, unmemocopy, SCM_CEVAL): Use SCM_IM_ELSE to memoize
1578 the syntactic keyword 'else.
1580 2003-10-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1582 * eval.c (s_bad_expression, syntax_error_key, syntax_error,
1583 ASSERT_SYNTAX, ASSERT_SYNTAX_2): New static identifiers.
1585 (scm_m_and): Use ASSERT_SYNTAX to signal syntax errors. Avoid
1586 unnecessary consing when creating the memoized code.
1588 2003-10-09 Kevin Ryde <user42@zip.com.au>
1590 * numbers.c (scm_inexact_to_exact): Don't depend on what double->long
1591 cast gives for values bigger than a long, or for nan or inf.
1593 2003-10-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1595 * smob.h (scm_make_smob_type): Made the declaration match the
1598 2003-10-07 Marius Vollmer <mvo@zagadka.de>
1600 * goops.c, objects.h, smob.c, smob.h: Make type names char
1601 const * instead of char *. Thanks to Paul Jarc!
1603 2003-10-02 Kevin Ryde <user42@zip.com.au>
1605 * strports.c (scm_call_with_output_string): scm_get_output_string
1606 rather than scm_strport_to_string, so as to guard against the port
1607 having been closed by the called procedure. Reported by Nic Ferrier.
1609 2003-09-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
1611 * numbers.h (SCM_INEXACTP): Removed uses of SCM_TYP16S.
1613 * tags.h, deprecated.h (SCM_TYP16S): Deprecated and moved from
1614 tags.h to deprecated.h.
1616 2003-09-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
1618 This set of patches introduces a new tc7 code scm_tc7_number for
1619 numbers. Bignums, reals and complex numbers are turned from smobs
1620 into subtypes of scm_tc7_number.
1622 * tags.h (scm_tc7_number): New.
1624 * eq.c (scm_equal_p), eval.c (SCM_CEVAL), evalext.c
1625 (scm_self_evaluating_p), gc-card.c (scm_i_sweep_card), gc-mark.c
1626 (scm_gc_mark_dependencies), goops.c (create_smob_classes), hash.c
1627 (scm_hasher), numbers.c, numbers.h (SCM_NUMP), objects.c
1628 (scm_class_of), print.c (scm_iprin1), smob.c
1629 (scm_smob_prehistory): Don't handle bignums, reals and complex
1630 numbers as subtypes of scm_tc7_smob any more.
1632 * numbers.h, tags.h (scm_tc16_big, scm_tc16_real,
1633 scm_tc16_complex): Moved definitions from tags.h to numbers.h.
1635 2003-09-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
1637 * numbers.c (scm_make_complex), gc-card.c (scm_i_sweep_card): Use
1638 sizeof (scm_t_complex) to determine the memory size of the
1639 malloc'd area for complex numbers.
1641 2003-09-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
1643 * numbers.c (scm_bigequal): Fixed.
1645 2003-09-16 Marius Vollmer <mvo@zagadka.de>
1647 * stime.c (scm_current_time): 'time' does not set errno so don't
1648 use SCM_SYSERROR for reporting errors.
1650 2003-09-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
1652 This set of patches eliminates the dependency between the
1653 implementation of evaluator specific memoization codes and special
1654 constants like #f, '() etc. ('flags'), which are not evaluator
1655 specific. The goal is to remove definitions of evaluator
1656 memoization codes completely from the public interface. This will
1657 make it possible to experiment more freely with optimizations of
1658 guile's internal representation of memoized code.
1660 * objects.c (scm_class_of): Eliminate dependency on SCM_ISYMNUM.
1662 * print.c (iflagnames): New array, holding the printed names of
1663 guile's special constants ('flags').
1665 (scm_isymnames): Now holds only the printed names of the
1668 (scm_iprin1): Separate the handling of memoization codes and
1669 guile's special constants.
1671 * tags.h (scm_tc9_flag, SCM_ITAG9, SCM_MAKE_ITAG9, SCM_ITAG9_DATA,
1674 (scm_tc8_char, scm_tc8_iloc, SCM_BOOL_F, SCM_BOOL_T,
1675 SCM_UNDEFINED, SCM_EOF_VAL, SCM_EOL, SCM_UNSPECIFIED, SCM_UNBOUND,
1676 SCM_ELISP_NIL, SCM_IM_DISPATCH, SCM_IM_SLOT_REF,
1677 SCM_IM_SLOT_SET_X, SCM_IM_DELAY, SCM_IM_FUTURE,
1678 SCM_IM_CALL_WITH_VALUES, SCM_IM_NIL_COND, SCM_IM_BIND): Changed
1681 (SCM_IFLAGP): SCM_IFLAGP now only tests for flags.
1683 (SCM_IFLAGP, SCM_MAKIFLAG, SCM_IFLAGNUM): Generalized to use the
1684 tc9 macros and scm_tc9_flag.
1686 2003-09-15 Marius Vollmer <mvo@zagadka.de>
1688 * posix.c (scm_setgroups): Check that the gid list is not too
1689 long. Thanks to Paul Jarc!
1691 2003-09-14 Dirk Herrmann <D.Herrmann@tu-bs.de>
1693 * tags.h: Reduced the number of short instructions from 14 to 13.
1694 The typecode of the former 14th short instruction is now used to
1695 represent long instructions. Changed some comments to reflect
1698 (SCM_MAKISYM): ISYMs get a new tc7 code, namely the one that was
1699 previously used by SCM_IM_DEFINE.
1701 (SCM_IM_DEFINE): Turned into a long instruction.
1703 * eval.c (unmemocopy, SCM_CEVAL): Treat SCM_IM_DEFINE as a long
1706 * eval.c (SCM_CEVAL): Since characters and iflags have now a tc7
1707 code that is separate from all instructions, one level of dispatch
1708 for long instructions can be eliminated.
1710 * print.c (scm_isymnames): Removed some commented code.
1712 2003-09-12 Marius Vollmer <mvo@zagadka.de>
1714 * __scm.h (SCM_FENCE): Use __memory_barrier with the Intel
1717 * hashtab.h (scm_tc16_hashtable): Added "extern" declaration.
1719 * modules.c (scm_module_reverse_lookup): Check that the obarray
1720 really is a hashtable and do nothing if not.
1722 * inline.h: Use "extern inline" only with GCC. Use "static
1725 2003-09-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
1727 * numbers.h (SCM_INEXACTP, SCM_REALP, SCM_COMPLEXP): Removed uses
1728 of SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP.
1730 * numbers.h, deprecated.h (SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP,
1731 SCM_SLOPPY_COMPLEXP): Deprecated and moved from numbers.h to
1734 2003-09-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
1736 * eq.c (scm_eqv_p, scm_equal_p): Removed uses of
1737 SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP.
1739 * eq.c (scm_eqv_p, scm_equal_p): Reordered comparisons from
1740 0.0==some_expression to some_expression==0.0. The latter is
1741 better readable. The former is preferred by some people, since it
1742 leads to a compiler error when confusing == with =. However, when
1743 using gcc, a warning will be issued if in an if-statement an
1744 assigment appears. Since many Guile developers are using gcc,
1745 such errors will not remain unnoticed anyway. We can therefore
1746 focus on better readability.
1748 2003-09-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
1750 * tags.h: Added description of Guile's type system. Removed some
1751 old and misleading comments.
1753 2003-09-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
1755 * unit.c (scm_cvref): Eliminate unnecessary uses of SCM_NIMP,
1756 SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP.
1758 2003-09-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
1760 * numbers.h (SCM_MAKINUM): Define in terms of scm_tc2_int.
1762 (SCM_INEXACTP, SCM_REALP, SCM_COMPLEXP): Define in terms of the
1763 respective SLOPPY macro.
1765 2003-09-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
1767 * eq.c (scm_equal_p): Use SCM_TYP7 to check if an object is of
1768 type string, not SCM_TYP7S.
1770 2003-09-03 Kevin Ryde <user42@zip.com.au>
1772 * numbers.c (scm_lognot): Correction to docstring, ones-complement not
1775 * stime.c (scm_strptime): Add comment about glibc strptime %s and
1776 current timezone requiring SCM_DEFER_INTS.
1778 2003-08-30 Neil Jerram <neil@ossau.uklinux.net>
1780 * script.c (scm_compile_shell_switches): Make -s switch optional
1781 if file to be loaded does not begin with a `-'. (Thanks to Aaron
1782 VanDevender for the patch!)
1784 2003-08-30 Kevin Ryde <user42@zip.com.au>
1786 * numbers.c (scm_lognot): Rewrite using ~ and mpz_com, for directness
1787 and to have non-integer types rejected as per other logical funcs.
1789 2003-08-28 Kevin Ryde <user42@zip.com.au>
1791 * gc.h (scm_remember_upto_here_1): Revise comments on the asm form.
1793 2003-08-23 Kevin Ryde <user42@zip.com.au>
1795 * simpos.c (scm_system): Remove SCM_DEFER_INTS, system() should be
1796 thread safe, and could take a long time too.
1798 2003-08-22 Kevin Ryde <user42@zip.com.au>
1800 * numbers.c (scm_difference): Correction to bignum - negative inum.
1802 2003-08-14 Kevin Ryde <user42@zip.com.au>
1804 * gc.h (scm_remember_upto_here_1, scm_remember_upto_here_2)
1805 [__GNUC__]: Use volatile asm macros rather than a function call.
1806 * gc.c (scm_remember_upto_here_1, scm_remember_upto_here_2): Undefine
1807 macros while defining functions.
1809 * simpos.c (getenv): Use <stdlib.h> for prototype.
1810 (scm_system): In docstring, refer to status:exit-val rather than
1813 2003-08-09 Kevin Ryde <user42@zip.com.au>
1815 * srcprop.c (scm_source_properties): Return plist from hash if it's a
1816 list set by source-properties! rather than an SRCPROPS object,
1818 2003-07-29 Kevin Ryde <user42@zip.com.au>
1820 * properties.c (scm_primitive_property_ref): In docstring, note
1821 parameters to not-found-proc, use hyphens rather than underscores for
1822 that parameter name.
1823 (scm_primitive_property_set_x): In docstring, VAL is the value
1826 2003-07-27 Marius Vollmer <mvo@zagadka.de>
1828 * print.c (scm_print_symbol_name): handle more weird characters by
1829 escaping the symbol name properly. Thanks to Paul Jarc!
1831 * posix.h (scm_setgroups): New prototype.
1832 * posix.c (scm_setgroups): New. Thanks to Paul Jarc!
1833 (scm_getgroups): Handle groups ids that don't fit into a fixnum.
1834 Don't use SCM_WRITABLE_VELTS.
1836 * gc.h (SCM_GC_SET_CELL_BVEC): New.
1837 * gc-card.c (scm_i_init_card_freelist): Use it. Thanks to
1840 * __scm.h (SCM_C_INLINE_KEYWORD): New.
1841 * numbers.c: Use it in place of SCM_C_INLINE so that the code
1842 compiles when SCM_C_INLINE is undefined.
1844 2003-07-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
1846 * __scm.h: Reformulated the architecture and compiler properties
1847 in terms of properties of scm_t_bits and SCM variables rather than
1848 in terms of c standard types. This is since it is not known which
1849 of the standard types scm_t_bits and SCM variables will be defined
1852 2003-07-24 Kevin Ryde <user42@zip.com.au>
1854 * numbers.c (scm_angle): Use scm_flo0 for non-negative inum, bignum
1857 2003-07-18 Kevin Ryde <user42@zip.com.au>
1859 * numbers.c (scm_product): In complex * bignum, correction to
1860 REAL/IMAG fetch, x is the complex, not y.
1862 2003-07-13 Mikael Djurfeldt <djurfeldt@nada.kth.se>
1864 * numbers.c (scm_odd_p, scm_even_p): Bugfix: Treat result of
1865 scm_inf_p test as Scheme values.
1866 (scm_sum): Bugfix: Normalize bignum created from a negative bignum
1867 and a positive inum.
1868 Use GNU indentation style.
1870 2003-07-12 Dirk Herrmann <D.Herrmann@tu-bs.de>
1872 * values.c (scm_values): Build lists of length 1 by using
1873 scm_list_1 instead of using scm_cons.
1875 2003-07-10 Kevin Ryde <user42@zip.com.au>
1877 * deprecation.c (scm_c_issue_deprecation_warning_fmt): Add va_end.
1878 * list.c (scm_list_n): Ditto.
1880 * gc-malloc.c (scm_gc_realloc): Define "ptr" at start of function.
1882 2003-07-08 Matthias Koeppe <mkoeppe@merkur.math.uni-magdeburg.de>
1884 * tags.h (scm_t_bits, scm_t_signed_bits, etc): Avoid solaris empty
1885 defines of INTPTR_MAX and UINTPTR_MAX, combine conditionals for
1886 scm_t_bits and scm_t_signed_bits to avoid any chance of one and not
1887 the other using intptr_t.
1889 2003-07-08 Kevin Ryde <user42@zip.com.au>
1891 * numbers.c (scm_make_polar): Use sincos, when available.
1892 (scm_magnitude): Use hypot.
1894 * ports.c (scm_char_ready_p, scm_peek_char): In docstrings, don't use
1895 @footnote since it doesn't go through to guile-procedures.txt.
1897 * threads.c (scm_call_with_new_thread): In docstring, use "( )"
1898 outside @var to quieten makeinfo, and use @code.
1900 2003-07-06 Han-Wen Nienhuys <hanwen@cs.uu.nl>
1902 * gc-malloc.c (decrease_mtrigger): new function
1903 (increase_mtrigger): new function, separate debug registering and
1904 mtrigger administration.
1905 (scm_gc_realloc): bugfix: do mtrigger administration before the
1906 actual realloc, for the realloc might invalidate a GC-d segment of
1907 memory. Thanks to Sam Hocevar for pointing this out.
1908 (scm_gc_realloc): use scm_malloc_reregister instead of
1909 unregistering and registering in sequence.
1911 2003-07-03 Han-Wen Nienhuys <hanwen@cs.uu.nl>
1913 * __scm.h (SCM_ASSERT): change "else" expansion to "do { } while (0)"
1915 2003-07-02 Han-Wen Nienhuys <hanwen@cs.uu.nl>
1917 * __scm.h (SCM_ASRTGO): add "else" to macro expansions with if
1920 2003-06-29 Marius Vollmer <mvo@zagadka.de>
1922 * deprecated.h (SCM_OPDIRP, scm_fport, scm_option, scm_srcprops,
1923 scm_srcprops_chunk, scm_info_frame, scm_stack, scm_array,
1924 scm_array_dim, SCM_ARRAY_CONTIGUOUS, SCM_FUNC_NAME, SCM_WTA,
1925 RETURN_SCM_WTA, SCM_VALIDATE_NUMBER_COPY,
1926 SCM_VALIDATE_NUMBER_DEF_COPY, SCM_VALIDATE_OPDIR): Re-added from
1927 the release_1_6 branch.
1929 2003-06-25 Stefan Jahn <stefan@lkcc.org>
1931 * continuations.c: Redeclaration of getcontext() via the
1932 __asm__ ("getcontext") directive.
1934 * continuations.h: Include <ucontext.h> instead of
1937 2003-06-21 Kevin Ryde <user42@zip.com.au>
1939 * numbers.c (_GNU_SOURCE): #define, to get C99 things.
1940 (scm_asinh, scm_acosh, scm_atanh, scm_truncate, $asinh, $acosh,
1941 $atanh, truncate): Use C library asinh, acosh, atanh and trunc, when
1943 (scm_inexact_to_exact): Expand isfinite to its definition !xisinf.
1944 (isfinite): Remove, conflicts with C99 isfinite().
1946 2003-06-19 Marius Vollmer <mvo@zagadka.de>
1948 * deprecated.h, deprecated.c (scm_strhash, scm_sym2ovcell_soft,
1949 scm_sym2ovcell, scm_intern_obarray_soft, scm_intern_obarray,
1950 scm_symbol_value0, scm_string_to_obarray_symbol scm_intern_symbol,
1951 scm_unintern_symbol, scm_symbol_binding, scm_symbol_interned_p,
1952 scm_symbol_bound_p, scm_symbol_set_x, scm_gentemp): Re-added from
1953 the release_1_6 branch.
1955 2003-06-14 Stefan Jahn <stefan@lkcc.org>
1957 * threads.h: Redefined scm_getspecific() and scm_setspecific()
1958 to be functions instead of macros.
1960 * threads.c: Conditionalized inclusion of <sys/time.h> and
1962 (scm_getspecific, scm_setspecific): Made these two function
1963 real part of the API.
1965 * posix.c (s_scm_putenv): Added some code to make a
1966 (putenv "FOO="), i.e. setting an empty string, work also on
1967 Win32 systems. Thanks to Kevin Ryde for the proposal.
1969 2003-06-12 Kevin Ryde <user42@zip.com.au>
1971 * posix.c (scm_putenv): Free temporary ptr in mingw unset. Add
1972 freebsd to comment about need to use unsetenv.
1974 2003-06-02 Marius Vollmer <mvo@zagadka.de>
1976 * ports.c (scm_peek_char): Safe the column of the port around the
1977 getc/ungetc calls. Thanks to Dr. Peter Ivanyi!
1979 2003-06-07 Kevin Ryde <user42@zip.com.au>
1981 * tags.h: Use inttypes.h and stdint.h when available, for INTPTR_MAX
1982 and friends required by scm_t_bits setups.
1984 2003-06-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
1986 * tags.h (scm_tc2_int): Added.
1988 * tags.h (scm_tc3_int_1, scm_tc3_int_2): Expressed in terms of
1991 * tags.h (scm_tcs_cons_imcar, scm_tcs_cons_nimcar, scm_tcs_struct,
1992 scm_tcs_closures): Hard coded values replaced by symbolic ones.
1994 2003-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1996 * eval.c: Partially undid my patch from 2003-05-31. This patch
1997 caused the segfault referenced in the previous changelog entry.
1999 2003-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
2001 * tags.h: Fixed comment about the immediate type code layout.
2003 * eval.c: Fixed handling of non-special instructions. Without
2004 this patch, guile will segfault on (#\0) and similar instructions.
2006 2003-06-05 Kevin Ryde <user42@zip.com.au>
2008 * numbers.c (scm_max, scm_min): For inum, bignum and real, if other
2009 operand is NaN, then return NaN. Also avoid passing NaN to mpz_cmp_d.
2011 * read.c (scm_input_error): Pass arg list parameter to scm_error_scm,
2012 rather than SCM_EOL. Needed by "Unknown # object" case in scm_lreadr.
2014 2003-06-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
2016 * __scm.h, gc-card.c (SCM_DEBUG_DEBUGGER_SUPPORT,
2017 SCM_DEBUG_DEBUGGING_SUPPORT): Renamed macro
2018 SCM_DEBUG_DEBUGGER_SUPPORT to SCM_DEBUG_DEBUGGING_SUPPORT and
2019 generalized it to apply not only to C level functions but also to
2020 scheme level functions.
2022 * debug.c, debug.h, eval.c (make-iloc, scm_make_iloc, iloc?,
2023 scm_iloc_p, dbg-make-iloc, scm_dbg_make_iloc, dbg-iloc?,
2024 scm_dbg_iloc_p): Moved functions scm_make_iloc, scm_iloc_p to
2025 eval.c, made them available under SCM_DEBUG_DEBUGGING_SUPPORT == 1
2026 only and renamed them to scm_dbg_make_iloc, scm_dbg_iloc_p,
2029 * deprecated.h, eval.c, eval.h (SCM_ILOC00, SCM_IDINC,
2030 SCM_IDSTMSK): Deprecated. The macro definitions are moved from
2031 eval.h into eval.c and a copy is placed into deprecated.h.
2033 * eval.c, eval.h (SCM_MAKE_ILOC): Removed from eval.h and placed
2034 into eval.c. This definition was not part of the API in any
2035 officially released version of guile and thus does not need to go
2036 through a phase of deprecation.
2038 2003-06-02 Dirk Herrmann <D.Herrmann@tu-bs.de>
2040 * deprecated.c, deprecated.h, eval.c, eval.h (scm_s_expression,
2041 scm_s_test, scm_s_body, scm_s_bindings, scm_s_variable,
2042 scm_s_clauses, scm_s_formals): Deprecated. In eval.c the
2043 definitions are make static and renamed from scm_s_xxx to s_xxx.
2044 In deprecated.c the original definitions are copied.
2046 * deprecated.h, eval.c, eval (SCM_EVALIM2, SCM_EVALIM, SCM_XEVAL,
2047 SCM_XEVALCAR): Deprecated. The macro definitions are moved from
2048 eval.h into eval.c and a copy (slightly modified to work in user
2049 code) is placed into deprecated.h.
2051 * eval.c: Use the local static s_xxx definitions instead of the
2052 scm_s_xxx definitions throughout.
2054 2003-06-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
2056 This set of patches separates the representation of the cxr family

2277 The purpose of this patch is to make guile's internal memoizers
2278 distinguishable from memoizing macros created on the scheme level
2279 or from user provided primitive memoizing macros. The reason is,
2280 that the internal memoizers are the only ones that are allowed to
2281 transform their scheme input into memoizer byte code, while all
2282 other memoizing macros may only transform scheme code into new
2285 To achieve this, a new macro type 'builtin-macro!' is introduced.
2286 Currently, 'builtin-macro!'s are handled as memoizing macros, but
2287 this will change when the memoizer and executor are separated.
2289 * macros.[ch] (scm_i_makbimacro): New.
2291 * macros.h (SCM_BUILTIN_MACRO_P): New.
2293 * macros.c (macro_print, scm_macro_type): Support builtin-macro!s.
2295 * eval.c, goops.c: All of guile's primitive memoizing macros are
2296 primitive builtin-macros now.
2298 * eval.c (scm_macroexp, SCM_CEVAL): Make sure the primitive
2299 builtin-macros are handled equally to memoizing macros.
2301 2003-05-04 Marius Vollmer <mvo@zagadka.de>
2303 * throw.c (scm_ithrow): Remove "asm volatile" hack. It used to
2304 work around a bug in GCC 2.95.2 but is now a bug in itself.
2306 2003-05-02 Marius Vollmer <mvo@zagadka.de>
2308 * deprecated.h (scm_rstate, scm_rng, SCM_SLOPPY_CONSP,

2331 macro was introduced in anticipation of GOOPS method compilation
2334 * goops.c: Removed binding of @dispatch.
2336 2003-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
2338 * eval.c, goops.c (@dispatch, @slot-ref, @slot-set!): Move the
2339 instructions that bind the macros on the scheme level back to
2340 goops.c in order to make sure again that the bindings go into the
2341 (oop goops) module and are not visible from the outside.
2343 2003-04-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
2345 * eval.c: Non functional change: Separated R5RS and non-R5RS
2346 macros into different sections of the file and ordered the
2347 memoizers alphabetically.

2362 scm_m_atslot_set_x, scm_m_atdispatch): Move the declarations and
2363 definitions of the special goops memoizers from goops.[ch] to
2364 eval.[ch]. Hmm... it seems that scm_m_atdispatch is not used

2388 This set of patches contains no functional changes, only debatable
2389 minor stylistic ones. Still, in order to prepare a patch between
2390 my local copy and the CVS version, I decided to submit the changes
2391 below. Then, the patch will hopefully only contain relevant
2394 * eval.c (iqq): Added const specifier.
2396 * eval.c (scm_trampoline_0, scm_trampoline_1, scm_trampoline_2):
2397 Use NULL instead of 0 to indicate that a pointer is returned.

2412 * sort.c, pairs.h: Removed unnecessary includes.
2414 2003-04-23 Dirk Herrmann <D.Herrmann@tu-bs.de>

2432 * sort.c (quicksort, SWAP, stack_node): Replaced pointer
2433 arithmetics with index arithmetics. Changed quicksort to work on
2434 an array of SCM values instead of an array of characters. Avoid
2435 bytewise copying of SCM elements. Avoid allocating memory on the
2436 stack with alloca. Fixed some comments.
2438 2003-04-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2440 * eval.c (EXTEND_ENV): Eliminated.

2455 scm_gc_marked_p, scm_gc_get_card, scm_gc_get_bvec): Fixed
2456 functions such that they check if the object is a non-immediate.
2457 Further, renamed identifiers to use the scm_dbg_ prefix and made
2458 their inclusion into the lib dependent of the
2459 SCM_DEBUG_DEBUGGER_SUPPORT compile time option.

2498 define the macro object.
2500 * eval.c, eval.h (s_set_x, scm_s_set_x, scm_m_set_x,
2501 scm_m_generalized_set_x): Since now scm_s_set_x is only used in
2502 eval.c, it is made static and renamed to s_set_x.
2504 * evalext.c (scm_defined_p, scm_m_undefine): Prefer !SCM_<foo>
2507 2003-04-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2509 * eval.c, root.h (scm_undefineds, SCM_NUM_PROTECTS, undefineds,
2510 scm_init_eval): Made scm_undefineds static in eval.c, renamed it
2511 to undefineds and registered the object as a permanent object.
2513 * eval.c, eval.h (scm_f_apply, scm_init_eval): Made scm_f_apply
2514 static in eval.c, renamed it to f_apply and registered the object
2515 as a permanent object.
2517 2003-04-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2519 * eval.c (SCM_BIT7, SCM_BIT8, unmemocopy, SCM_CEVAL): Renamed
2520 file-local macro SCM_BIT8 to SCM_BIT7, which is more appropriate.
2522 2003-04-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2524 * numbers.c (scm_logtest): Fixed argument bug in the call to
2525 mpz_and, which showed up when compiling with SCM_DEBUG defined.

3071 #include <config.h> if HAVE_CONFIG_H.
3073 * coop-threads.c: #include "libguile/_scm.h" early. Replace
3074 usage of struct timespect with scm_t_timespec. Replace usage of
3075 STACK_GROWS_UP with SCM_STACK_GROWS_UP.

3078 usage of struct timespect with scm_t_timespec. Replace usage of
3079 STACK_GROWS_UP with SCM_STACK_GROWS_UP.
3081 * coop-defs.h: move handling of time related headers to
3082 scmconfig.h. Add #include "libguile/__scm.h". Rename usage of
3083 HAVE_WINSOCK2_H to SCM_HAVE_WINSOCK2_H. Replace usage of struct
3084 timespect with scm_t_timespec.
3086 * convert.i.c: rename usage of HAVE_ARRAYS to SCM_HAVE_ARRAYS.
3088 * convert.h: rename usage of HAVE_ARRAYS to SCM_HAVE_ARRAYS.
3090 * convert.c: #include <config.h> if HAVE_CONFIG_H. Rename usage
3091 of HAVE_ARRAYS to SCM_HAVE_ARRAYS.
3093 * continuations.c: move libguile/_scm.h include to the top so we
3094 pick up any critical defines like _GNU_SOURCE early.
3096 * backtrace.c: #include <config.h> if HAVE_CONFIG_H.
3098 * async.c: #include <config.h> if HAVE_CONFIG_H.

3108 appropriate. STDC_HEADERS based inclusion of stdlib.h,
3109 sys/types.h, stddef.h, and sys/stdtypes.h removed in favor of

3113 (HAVE_UINTPTR_T): definition removed (see NEWS).
3114 (SIZEOF_PTRDIFF_T): definition removed (see NEWS).
3115 (HAVE_LONG_LONGS): definition removed (see NEWS).
3116 (HAVE_LONG_LONG): definition removed (see NEWS).
3117 (HAVE_PTRDIFF_T): definition removed (see NEWS).
3119 * Makefile.am: scmconfig.h is now generated by building and
3120 running gen-scmconfig.h and capturing its output. gen-scmconfig
3121 uses config.h and the configure.in generated gen-scmconfig.h to
3122 decide what to output. See gen-scmconfig.c for details.
3123 (noinst_PROGRAMS): add gen-scmconfig.
3124 (gen_scmconfig_SOURCES): new variable.
3125 (gen-scmconfig.$(OBJEXT)): new target - be careful to handle
3126 cross-compiling right.
3127 (scmconfig.h): build scmconfig.h from gen-scmconfig's output.
3128 (BUILT_SOURCES): add scmconfig.h.
3130 2003-03-19 Marius Vollmer <mvo@zagadka.de>
3132 * gc_os_dep.c: Added defines for sparc-unknown-netbsdelf1.5 from
3133 Adrian Bunk. Thanks!
3135 2003-03-19 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3137 * goops.c (make_class_from_template): New fourth arg:
3139 (scm_class_extended_generic_with_setter, scm_class_self): Fixed
3142 * smob.c (scm_set_smob_apply): Call scm_i_inherit_applicable.
3144 * goops.c, objects.c, objects.h (scm_make_extended_class): New
3145 second arg: applicablep.
3146 (scm_i_inherit_applicable): New function.
3148 * goops.c, goops.h (scm_class_applicable,
3149 scm_class_extended_accessor): New classes.
3151 2003-03-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
3153 * procs.c (scm_procedure_documentation): Removed redundant
3154 SCM_NIMP test and replaced other calls to SCM_IMP by more explicit
3157 2003-03-11 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3159 * list.c, list.h (scm_filter, scm_filter_x): New functions.
3161 * modules.c (scm_module_import_interface): New function.
3163 * goops.c, goops.h (scm_class_accessor_method): Renamed from

3175 * snarf.h (SCM_PRIMITIVE_GENERIC, SCM_PRIMITIVE_GENERIC_1): New
3178 * numbers.c (scm_abs): Use SCM_PRIMITIVE_GENERIC. (This is only a
3179 testing example. All uses of SCM_GPROC should be converted.)
3181 * procprop.c (scm_stand_in_scm_proc): Use scm_assq instead of
3184 * eq.c (scm_equal_p): Turned into a primitive generic.
3186 2003-02-27 Rob Browning <rlb@defaultvalue.org>
3188 * Makefile.am (scmconfig.h): new target -- generate file from
3190 (modinclude_HEADERS): remove version.h.
3191 (nodist_modinclude_HEADERS): add version.h.
3193 2003-02-24 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3195 This fixes a serious GC bug, introduced during the latest
3196 reorganization of the GC, which disabled freeing of structs and
3199 * struct.c (scm_struct_prehistory): Init scm_i_structs_to_free to
3201 (scm_struct_prehistory): Move scm_free_structs to
3202 scm_before_mark_c_hook.
3204 * gc-card.c (sweep_card): Check that we haven't swept structs on
3205 this card before. That can happen if scm_i_sweep_all_segments has
3206 been called from some other place than scm_igc.
3208 2003-02-19 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3210 * environments.c (DEFAULT_OBARRAY_SIZE): Changed from 137 to 31
3211 (since hash tables now adapt their size).
3213 * modules.c (scm_modules_prehistory): Changed from 2001 to 1533
3214 (current number of prehistory bindings; hashtable code will select
3215 a prime which is greater than this value).
3217 * symbols.c (scm_symbols_prehistory): Changed from 1009 to 2139
3218 (current number of initial symbols).
3220 * properties.c (scm_init_properties): Don't specify size of
3221 scm_properties_whash.
3223 * objprop.c (scm_init_objprop): Don't specify size of
3226 * keywords.c (scm_init_keywords): Don't specify a hash table size.
3228 * hooks.c (scm_c_hook_add): Fixed bug in append mode.
3230 The following changes introduce the use of resizable hash tables
3231 throughout Guile. It also renames the old *-hash-table* functions
3232 to *-alist-vector* and places them, together with the rest of the
3233 weak vector support, in the module (ice-9 weak-vector). We should
3234 probably introduce a new, better, API for weak references, for
3235 example "weak pairs" a la MIT-Scheme. (In Chez scheme, they even
3236 look like and are used like ordinary pairs.)
3238 * environments.c (obarray_enter, obarray_retrieve, obarray_remove,
3239 leaf_environment_fold, obarray_remove_all): Use hashtable
3242 * gc.c (scm_init_storage): Moved hook initialization to
3243 scm_storage_prehistory.
3244 (scm_storage_prehistory): New function.
3245 (scm_igc): Added commentary about placement of
3246 scm_after_sweep_c_hook.
3248 * gc-mark.c (scm_mark_all): Use hashtable accessors.
3249 (scm_gc_mark_dependencies): Use SCM_WVECT_WEAK_KEY_P and
3250 SCM_WVECT_WEAK_VALUE_P.
3252 * hashtab.c, hashtab.h (scm_hash_for_each, scm_hash_map): New
3254 (scm_vector_to_hash_table, scm_c_make_resizing_hash_table):
3256 (scm_make_weak_key_hash_table, scm_make_weak_value_hash_table,
3257 scm_make_doubly_weak_hash_table): Moved here from weaks.c.
3259 * init.c (scm_init_guile_1): Removed call to scm_init_weaks; Added
3260 calls to scm_storage_prehistory and scm_hashtab_prehistory.
3262 * modules.c (module-reverse-lookup): Use hashtable accessors.
3264 * symbols.c, symbols.h (scm_i_hash_symbol): New function.
3266 * weaks.c, weaks.h (scm_make_weak_key_alist_vector,
3267 scm_make_weak_value_alist_vector,
3268 scm_make_doubly_weak_alist_vector): New functions.
3270 * weaks.c (scm_init_weaks_builtins): New function.
3272 * weaks.h (SCM_WVECTF_WEAK_KEY, SCM_WVECTF_WEAK_VALUE,
3273 SCM_WVECTF_NOSCAN, SCM_WVECT_WEAK_KEY_P, SCM_WVECT_WEAK_VALUE_P,
3274 SCM_WVECT_NOSCAN_P): New macros.
3276 * weaks.c (scm_scan_weak_vectors): Use SCM_WVECT_WEAK_KEY_P
3277 and SCM_WVECT_WEAK_VALUE_P.
3279 * weaks.c, weaks.h (scm_i_allocate_weak_vector): Renamed from
3280 allocate_weak_vector and exported.
3282 2003-02-13 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3284 * hashtab.c: Undid thread safety. (We decided that it's better to
3285 let the user explicitly protect the tables (or not) according what
3286 is suitable for the application.)
3288 2003-02-12 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3290 * hashtab.c (scm_hash_fn_remove_x, scm_internal_hash_fold): Made
3291 thread safe and handle resizing tables.
3292 (scm_ihashx, scm_sloppy_assx, scm_delx_x): Removed
3293 SCM_DEFER/ALLOW_INTS.
3295 2003-02-11 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3297 * hashtab.c (scm_vector_to_hash_table,
3298 scm_c_make_resizing_hash_table, scm_make_hash_table): New
3300 (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x): Made thread
3301 safe and handle resizing tables.
3303 * weaks.c (scm_make_weak_key_hash_table,
3304 scm_make_weak_value_hash_table, scm_make_doubly_weak_hash_table):
3305 Size argument made optional. Return resizable table if not
3308 2003-02-10 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3310 * eval.c (scm_trampoline_0, scm_trampoline_1, scm_trampoline_2):
3311 Fixed formals tests for closures. (Thanks to Kevin Ryde.)
3313 2003-02-05 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3315 * debug.c (scm_procedure_source): Handle all objects for which
3316 procedure? is #t. (Thanks to Bill Schottstaedt.)
3318 2003-01-23 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3320 * futures.c (mark_futures): Don't need to mark data of recycled
3322 (scan_futures, cleanup_undead): Be smarter about marking
3323 futures---avoid unnecessary passes through future lists.
3325 * futures.h, futures.c: New files; Introduced recycling of
3326 futures. For fine-grained threading this lifts performance to
3327 another level. We can now use parallelization in inner loops of
3328 Guile programs without impossible overhead.
3330 * threads.h, threads.c: Moved futures to their own file.
3332 * Makefile.am (libguile_la_SOURCES): Added futures.c.

3356 2003-01-22 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3358 * threads.c (create_thread): Don't unwind dynwind chain of parent
3359 thread before creation. Just start the new thread with an empty

3369 waiting also for simple condition variables.
3371 * goops.c (TEST_CHANGE_CLASS): Use scm_change_object_class instead

3376 * ramap.c (scm_ramapc): Typo in error message.
3378 2003-01-08 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3380 * goops.c (scm_sys_prep_layout_x): Bugfix: Only create layout for
3381 slots with instance allocation.
3383 * goops.c, goops.h (scm_class_extended_generic_with_setter): New
3385 (scm_compute_applicable_methods): Use scm_generic_function_methods.

3390 2002-12-29 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3392 * eval.c (unmemocopy): Bugfix: scm_sym_delay --> scm_sym_future.
3393 Thanks to Neil for pointing this out!
3395 2002-12-29 Neil Jerram <neil@ossau.uklinux.net>
3397 * lang.h: Remove declarations matching definitions removed from
3398 lang.c (just below).

3403 scm_m_while, scm_nil_eq): Remove definitions that were superfluous
3404 and already commented out.
3406 * read.h (scm_lreadparen), read.c (scm_lreadr, scm_read_token,
3407 scm_lreadparen): Support reading vectors with Elisp syntax if
3408 SCM_ELISP_READ_EXTENSIONS is defined. (SCM_ELISP_READ_EXTENSIONS
3409 is not currently defined, and there isn't even a configure switch
3412 2002-12-26 Marius Vollmer <mvo@zagadka.ping.de>
3414 * Makefile.am (c-tokenize.o): Refer to source via $< so that vpath
3416 (EXTRA_DIST): Added version.h.in.
3418 2002-12-21 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3420 This change makes it possible for one thread to do lazy sweeping
3421 while other threads are running. Now only the mark phase need to
3422 have all threads asleep. We should look further into this issue.
3423 Presently, I've put the locking of scm_i_sweep_mutex at
3424 "conservative" places due to my current lack of knowledge about
3425 the garbage collector. Please feel free to restrict these regions
3426 further to allow for maximal parallelism!
3428 * gc.c, gc.h (scm_i_sweep_mutex): New mutex.

3435 the single-thread section (which now only contains the mark
3437 (scm_gc): Don't lock sweeo mutex here since scm_igc locks it;
3438 Removed SCM_DEFER/ALLOW_INTS. Simply call scm_igc directly.
3440 * threads.c (gc_section_mutex): Removed.
3442 2002-12-19 Mikael Djurfeldt <mdj@kvast.blakulla.net>
3444 * threads.c (create_thread): Clear parent field in root state in
3445 order not to unnecessarily remember dead threads.

3472 thread_admin_mutex locked during GC.
3474 * pthread-threads.c, pthread-threads.h: Improvements to debugging
3477 2002-12-16 Mikael Djurfeldt <mdj@kvast.blakulla.net>
3479 * pthread-threads.c, pthread-threads.h (SCM_DEBUG_THREADS): Added
3480 support for debugging mutex operations.

3490 unintended destruction).
3491 (scm_threads_prehistory): Initialize heap_mutex of fake thread.
3493 * pthread-threads.c, pthread-threads.h, threads.c: Fixes to
3494 pthread "native" recursive mutex support.

3501 SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START,
3502 SCM_REC_CRITICAL_SECTION_END): Removed.
3504 * eval.c: Replaced SOURCE_SECTION_START / SOURCE_SECTION_END with
3505 direct calls to scm_rec_mutex_lock / unlock around the three calls
3506 to scm_m_expand_body.
3508 * eval.c, eval.h (promise_free): New function.
3509 (scm_force): Rewritten; Now thread-safe; Removed
3510 SCM_DEFER/ALLOW_INTS.
3512 * pthread-threads.h: Added partially implemented plugin interface
3513 for recursive mutexes. These are, for now, only intended to be
3514 used internally within the Guile implementation.
3516 * pthread-threads.c: New file.
3518 * threads.c: Conditionally #include "pthread-threads.c".
3520 * eval.c, eval.h (scm_makprom, scm_force): Rewritten to be
3523 * snarf.h (SCM_MUTEX, SCM_GLOBAL_MUTEX, SCM_REC_MUTEX,

3550 * threads.c (create_thread): Remember root object until the handle
3551 of the new thread is on all_threads list.
3553 * root.c (scm_make_root): Moved copying of fluids until after
3554 creation of root handle so that the fluids are GC protected. Also
3555 removed the critical section.
3557 2002-12-10 Mikael Djurfeldt <mdj@kvast.blakulla.net>

3594 2002-12-10 Mikael Djurfeldt <djurfeldt@nada.kth.se>

3606 * __scm.h (SCM_DEFER_INTS, SCM_ALLOW_INTS): Define as a recursive
3608 (SCM_REDEFER_INTS, SCM_ALLOW_INTS): Define as SCM_DEFER_INTS and
3611 2002-12-09 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3613 * threads.c (scm_mutex_lock, scm_cond_wait, scm_cond_timedwait):
3614 Removed accidental #if 0 around these functions.
3616 These changes are the start of support for preemptive
3617 multithreading. Marius and I have agreed that I commit this code
3618 into the repository although it isn't thoroughly tested and surely
3619 introduces many bugs. The bugs should only be exposed when using
3620 threads, though. Signalling and error handling for threads is
3621 very likely broken. Work on making the implementation cleaner and
3622 more efficient is needed.
3624 * __scm.h (SCM_ALLOW_INTS_ONLY): Removed.
3625 (SCM_NONREC_CRITICAL_SECTION_START,
3626 SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START,
3627 SCM_REC_CRITICAL_SECTION_END): New macros.
3628 (SCM_CRITICAL_SECTION_START/END): Defined here.
3630 * eval.c: Insert SOURCE_SECTION_START / SOURCE_SECTION_END around
3631 the three calls to scm_m_expand_body.
3633 * gc.h: #include "libguile/pthread-threads.h";
3634 (SCM_FREELIST_CREATE, SCM_FREELIST_LOC): New macros.
3636 * gc.c (scm_i_freelist, scm_i_freelist2): Defined to be of type
3639 * gc.c, gc-freelist.c, inline.h: Use SCM_FREELIST_LOC for freelist
3642 * gc-freelist.c (scm_gc_init_freelist): Create freelist keys.
3644 * gc-freelist.c, threads.c (really_launch): Use
3645 SCM_FREELIST_CREATE.
3647 * gc-malloc.c (scm_realloc, scm_gc_register_collectable_memory):
3649 * gc.c (scm_i_expensive_validation_check, scm_gc,
3650 scm_gc_for_newcell): Put threads to sleep before doing GC-related
3651 heap administration so that those pieces of code are executed
3652 single-threaded. We might consider rewriting these code sections
3653 in terms of a "call_gc_code_singly_threaded" construct instead of
3654 calling the pair of scm_i_thread_put_to_sleep () and
3655 scm_i_thread_wake_up (). Also, we would want to have as many of
3656 these sections eleminated.
3658 * init.c (scm_init_guile_1): Call scm_threads_prehistory.
3660 * inline.h: #include "libguile/threads.h"
3662 * pthread-threads.h: Macros now conform more closely to the
3663 pthreads interface. Some of them now take a second argument.
3665 * threads.c, threads.h: Many changes.
3667 2002-12-09 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3669 * Makefile.am (version.h): Changed $^ --> $< in rule for
3672 2002-12-08 Rob Browning <rlb@defaultvalue.org>
3674 * version.h.in (SCM_MICRO_VERSION): use @--@ substitution now.
3675 (SCM_MINOR_VERSION): use @--@ substitution now.
3676 (SCM_MICRO_VERSION): use @--@ substitution now.
3677 (scm_effective_version): new function prototype.
3679 * version.c (scm_effective_version): new function, also add
3682 * Makefile.am (schemelibdir): VERSION -> GUILE_EFFECTIVE_VERSION.
3683 (libpath.h): use GUILE_EFFECTIVE_VERSION to compute
3685 (version.h): generate this here rather than configure.in. This
3686 approach tracks source edits better (i.e. more immediately).
3687 Might be worth considering for other .in files too.
3689 2002-12-02 Marius Vollmer <mvo@zagadka.ping.de>
3691 Reorganized thread package selection. A thread package now only
3692 implements a small set of pthread like functions and Guile
3693 implements the rest on top of that. Guile's implementation is
3694 what the "coop-pthreads" package has been previously. Support for
3695 "coop" threads has been removed until I get time to add it again.
3697 * Makefile.am (libguile_la_SOURCES): Removed iselect.c.
3698 (noinst_HEADERS): Removed coop-threads.c, coop-threads.h, coop.c,
3699 null-threads.c, coop-pthreads.c.
3700 (modinclude_HEADERS): Removed coop-defs.h, coop-pthreads.h. Added
3703 * validate.h (SCM_VALIDATE_THREAD): Moved to threads.h.
3705 * threads.h: Do not include "libguile/coop-defs.h". Include
3706 "libguile/pthread-threads.h" for USE_COPT_THREADS. Removed
3707 (previously deprecated) C level thread API prototypes. They are
3708 now in the thread package specific headers, "null-threads.h" and
3709 "pthread-threads.h".
3710 (SCM_VALIDATE_THREAD, SCM_VALIDATE_MUTEX, SCM_VALIDATE_CONDVAR):
3712 (scm_threads_init): Removed.
3713 (SCM_CRITICAL_SECTION_START, SCM_CRITICAL_SECTION_END,
3714 SCM_THREAD_SWITCHING_CODE, scm_i_switch_counter,
3715 SCM_I_THREAD_SWITCH_COUNT): Define here.
3716 (scm_single_thread_p): Removed.
3717 (scm_call_with_new_thread): Take two args directly instead of list
3719 (scm_i_thread_data, scm_i_set_thread_data, SCM_THREAD_LOCAL_DATA,
3720 SCM_SET_THREAD_LOCAL_DATA): Define here.
3722 * threads.c: Merged with "coop-pthreads.c".
3724 * null-threads.h: Implement pthread-like API as a set of macros.
3726 * pthread-threads.h: New, implement pthread-like API by deferring
3729 * init.c (scm_init_guile_1): Do not call scm_init_iselect, which
3730 has been lost in the reorganization.
3732 2002-12-01 Mikael Djurfeldt <mdj@linnaeus>
3734 The following change makes it possible to move procedure
3735 application dispatch outside inner loops. The motivation was
3736 clean implementation of efficient replacements of R5RS primitives
3739 The semantics is clear: scm_trampoline_N returns an optimized
3740 version of scm_call_N (or NULL if the procedure isn't applicable
3743 Applying the optimization to map and for-each increases efficiency
3744 noticeably. For example, (map abs ls) is 8 times faster than
3747 * eval.h (scm_t_trampoline_1, scm_t_trampoline_2): New types.
3749 * eval.c, eval.h (scm_trampoline_1, scm_trampoline_2): New functions.
3751 * eval.c (call_subr2_2, call_lsubr_2, call_closure_2): New functions;
3752 (map, for-each): Handle also application on two args as a special
3753 case; Use trampolines.
3757 * sort.c (scm_cmp_function): Choose subr2less for scm_tc7_subr_2o;
3758 (subr2oless): Removed.
3759 (scm_restricted_vector_sort_x): Use scm_return_first to keep the
3760 vector GC protected.
3762 * eval.c (check_map_args): Use scm_out_of_range_pos instead of
3765 2002-11-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
3767 * evalext.[ch] (scm_m_undefine, undefine): Deprecated.
3769 2002-11-17 Mikael Djurfeldt <mdj@linnaeus>

3773 2002-11-17 Marius Vollmer <mvo@zagadka.ping.de>
3775 * strports.c (scm_eval_string_in_module): Validate second arg to
3776 be a module. Thanks to Arno Peters!
3778 2002-11-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
3780 * .cvsignore: remove goops.c
3782 2002-11-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
3784 * modules.c (scm_env_top_level, scm_lookup_closure_module,
3785 module_variable, scm_module_lookup_closure,
3786 scm_module_transformer, scm_sym2var, scm_module_reverse_lookup,
3787 scm_system_module_env_p): Don't compare SCM values with C
3788 operators == or !=. Avoid SCM_IMP predicates. Prefer !SCM_FALSEP
3791 2002-11-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
3793 * eval.h (SCM_MAKE_ILOC): New macro.
3795 * debug.c (scm_make_iloc): Use SCM_MAKE_ILOC instead of computing
3796 the iloc bitpattern here.
3798 2002-11-14 Mikael Djurfeldt <mdj@linnaeus>
3800 * coop-pthreads.c, coop-pthreads.h: scm_internal_select should be
3801 part of the API, otherwise it's difficult to write Guile
3802 extensions using non-blocking I/O => moved #include
3803 "libguile/iselect.h" from coop-pthreads.c --> coop-pthreads.h.
3805 * coop-pthreads.c (scm_unlock_mutex): Changed s_lock_mutex -->
3808 2002-11-10 Marius Vollmer <mvo@zagadka.ping.de>
3810 * __scm.h (USE_THREADS, GUILE_ISELECT): Do not define here. They
3811 are defined in configure.in.
3813 * threads.c: Removed SCM_API from function definitions. SCM_API
3814 is only for declarations.
3816 2002-11-07 Mikael Djurfeldt <mdj@linnaeus>
3818 * coop-pthreads.h: Added support for thread specific data to the
3819 generic C API for the coop-pthreads case.
3821 * threads.c, threads.h (scm_cond_init): Undo unintentional API
3823 (scm_cond_broadcast): Added missing function.
3825 2002-11-04 Marius Vollmer <marius.vollmer@uni-dortmund.de>
3827 * coop.c (coop_next_runnable_thread): Removed, wich should have
3828 happened when GUILE_ISELECT was hard-wired.
3830 2002-11-03 Marius Vollmer <mvo@zagadka.ping.de>
3832 * Makefile.am (libguile_la_SOURCES): Added threads.c

3839 * __scm.h (USE_THREADS, GUILE_ISELECT): Define when
3840 SCM_DEBUG_DEPRECATED. Removed their use thru-out Guile.
3842 * iselect.c: Include "_scm.h" before testing HAVE_UNISTD_H.
3843 Thanks to Bill Schottstaedt!
3845 * numbers.c (scm_integer_expt): Make 0^z == 0 for z != 0.
3847 * _scm.h (HAVE_RESTARTABLE_SYSCALLS): Do define even when
3848 SCM_COPT_THREADS is defined.
3849 (SCM_SYSCALL): Use EINTR-expection version when SCM_COPT_THREADS
3852 * coop-pthreads.c: Some harmless renamings of internal stuff.
3853 (create_thread): New, generalized version of
3854 scm_call_with_new_thread.
3855 (scm_call_with_new_thread): Use it.

3858 2002-11-02 Marius Vollmer <mvo@zagadka.ping.de>
3860 * coop-pthreads.c, coop-pthreads.h: Redone completely, you might
3861 start testing it now.
3863 * _scm.h: Include <errno.h< so that SCM_SYSCALL is correctly
3864 defined when HAVE_RESTARTABLE_SYSCALLS is not defined.
3865 (HAVE_RESTARTABLE_SYSCALLS): Do not define when USE_COPT_THREADS
3868 2002-10-27 Marius Vollmer <mvo@zagadka.ping.de>

3871 scm_delq_spine_x, really_install_handler, install_handler): New
3872 scheme for triggering signal handlers, to simplify take_signal.
3873 (take_signal): Simplified, to avoid race conditions.
3874 (scm_sigaction_for_thread): Use new Scheme. Validate that thread
3877 * async.c (scm_async_click): Reset pending_asyncs, handle
3878 signal_asyncs. Don't set cdr of a non-signal async to #f.
3879 (scm_i_queue_async_cell): Do not check cdr of cell for #f, queue
3880 always. Set pending_asyncs.
3881 (scm_system_async_mark_for_thread): Check that thread has not
3883 (scm_unmask_signals, decrease_block): Call scm_async_click after
3884 block_asyncs becomes zero.
3886 * __scm.h (SCM_ASYNC_CLICK): Check pending_asyncs instead of

3897 one for USE_NULL_THREADS.
3898 (scm_init_iselect): Likewise.
3900 * inline.h (scm_cell, scm_double_cell): Also allow
3901 USE_COPT_THREADS to not protect the slot initializers.
3903 * init.c (scm_init_guile_1): Call scm_init_thread_procs. This is
3904 because threads need to be initialized before the stack, but
3905 gsubrs such as scm_timed_condition_variable_wait can only be
3908 * threads.h: Include "coop-pthreads.h" when requested.
3909 (scm_threads_make_mutex, scm_threads_lock_mutex,
3910 scm_threads_unlock_mutex, scm_threads_monitor): Removed, they were
3911 not implemented anyway.

3927 registered procedures.
3928 (scm_wait_condition_variable, scm_timed_wait_condition_variable):
3929 Use the latter as the procedure for "wait-condition-variable",
3930 thus offering a optional timeout parameter to Scheme.
3931 (scm_wait_condition_variable): Implement in terms of
3932 scm_timed_wait_condition_variable.
3933 (scm_mutex_init, scm_mutex_lock, scm_mutex_trylock,
3934 scm_mutex_unlock, scm_mutex_destroy, scm_cond_init,
3935 scm_cond_wait, scm_cond_timedwait, scm_cond_signal,
3936 scm_cond_broadcast, scm_cond_destroy): Implement in terms of
3937 scm_make_mutex, etc, and deprecate.

3948 scm_cond_wait, scm_cond_signal, scm_cond_broadcast,
3949 scm_cond_destory): Do not define, they are now deprecated and
3950 handled by threads.{h,c}.
3952 * null-threads.c (scm_null_mutex, scm_null_cond): Define here.
3953 (scm_threads_init): Create smobs here, using the appropriate
3955 (block): Removed, now unused.
3956 (scm_c_thread_exited_p): New.
3957 (scm_null_mutex_init, scm_null_mutex_lock, scm_null_mutex_unlock,
3958 scm_null_mutex_destroy, scm_null_condvar_init,
3959 scm_null_condvar_wait, scm_null_condvar_signal,
3960 scm_null_condvar_destroy): Removed and updated users to do their
3962 (scm_try_mutex, timeval_subtract,
3963 scm_timed_wait_condition_variable,
3964 scm_broadcast_condition_variable): New.

4026 * scmsigs.c (scm_sigaction_for_thread): It's "USE_THREADS" not
4029 * Makefile.am (noinst_HEADERS): Added null-threads.c.
4030 (modinclude_HEADERS): Added null-threads.h.
4032 * threads.h: Include null-threads.h when !USE_COOP_THREADS.
4033 * threads.c: Include null-threads.c when !USE_COOP_THREADS.
4034 (scm_init_threads): Use generic type names scm_t_mutex and

4039 2002-10-15 Marius Vollmer <mvo@zagadka.ping.de>
4041 * Makefile.am: Replaced "$<" in non-pattern rules with its value.
4042 This is to support makes that know about "$<" only in pattern
4043 rules, like Sun's make.
4045 2002-10-13 Marius Vollmer <mvo@zagadka.ping.de>
4047 * Makefile.am (libpath.h): Fixed typo in top_srcdir_absolute

4057 * async.c (scm_system_async_mark_for_thread): Only call
4058 scm_i_thread_root when USE_THREADS is defined. Use scm_root
4061 * scmsigs.c (take_signal): Only call scm_i_thread_root when
4062 USE_THREADS is defined. Use scm_root otherwise.
4063 (scm_sigaction_for_thread): Ignore THREAD argument when
4064 USE_THREADS is not defined. Also, move THREAD argument defaulting
4065 out of HAVE_SIGACTION section, which was a bug.
4067 2002-10-10 Marius Vollmer <marius.vollmer@uni-dortmund.de>
4069 * scmsigs.c (scm_sigaction_for_thread): Store original handler in
4070 signal_handlers, not the closure that is used as the async.
4071 The closure is stored in signal_handler_cells, as previously.
4073 2002-10-10 Marius Vollmer <mvo@zagadka.ping.de>
4075 * root.h (scm_root_state): Added 'block_async' slot.

4091 (scm_mask_signals, scm_unmask_signals): Deprecated. Emit
4092 deprecation warning and check for errornous use. Set block_asyncs
4093 instead of scm_mask_ints.

4144 (sys_deliver_signals): Removed.
4146 (scm_sigaction_for_thread): Renamed from scm_sigaction and
4147 extended to also set the thread of a signal and allocate a cell
4148 for it. Keep the Scheme name "sigaction". Check that signum is
4149 within range. Also, use SCM_VECTOR_REF instead of SCM_VELTS.
4150 (scm_sigaction): Implement in terms of scm_sigaction_for_thread.
4151 (scm_init_scmsigs): Allocate signal_handler_cells and
4152 signal_handler_threads vectors.
4154 * async.c: Removed GUILE_OLD_ASYNC_CLICK code. Reorganized so

4156 system asyncs to work per-thread.
4158 * gc.c (scm_init_gc): Do not use scm_system_async.

4246 * vectors.h (SCM_VECTOR_REF): New.
4248 * snarf.h (SCM_DEFINE_PUBLIC): New.
4250 2002-08-30 Marius Vollmer <mvo@zagadka.ping.de>
4252 * socket.c (scm_addr_vector): Added size of address to arguments.
4253 Use it to avoid accessing a non-existent path in a sockaddr_un.
4254 Changed all callers.
4256 2002-08-29 Han-Wen Nienhuys <hanwen@cs.uu.nl>
4258 * gc.h: remove DOUBLECELL card flags.
4260 * gc-malloc.c (scm_calloc): try to use calloc() before calling
4263 * gc-segment.c (scm_i_initialize_heap_segment_data): remove card
4264 init loop; handle this from scm_init_card_freelist()
4266 * gc-card.c (scm_init_card_freelist): init bit vector here.
4268 * numbers.c (scm_make_real): prevent reordering of statements

4278 years. Thanks to Martin Grabmüller!
4280 2002-08-25 Han-Wen Nienhuys <hanwen@cs.uu.nl>
4282 * gc-segment.c (scm_i_get_new_heap_segment): use float in stead of
4283 unsigned numbers for computing minimum heap increment. This
4284 prevents weird results when a a negative minimum increment is
4287 2002-08-24 Marius Vollmer <mvo@zagadka.ping.de>
4289 * gc_os_dep.c: When we have __libc_stack_end, use that directly
4290 instead of the old tricks.
4292 * guile-snarf.in: Do not expect the input file to be the first
4293 argument after the optional "-o" option, just pass everything to
4294 the pre-processor without extracting the input file name.
4296 2002-08-23 Han-Wen Nienhuys <hanwen@cs.uu.nl>
4298 * gc-segment.c (scm_i_get_new_heap_segment): Oops. We want segment
4299 length *at* least SCM_MIN_HEAP_SEG_SIZE, not at most.
4301 2002-08-22 Han-Wen Nienhuys <hanwen@cs.uu.nl>
4303 * gc.h, gc.c: make scm_cells_allocated unsigned again. Thanks to

4316 2002-08-17 Han-Wen Nienhuys <hanwen@cs.uu.nl>
4318 * ports.c (scm_add_to_port_table): small bugfix.
4320 * mallocs.c (scm_malloc_obj): use scm_gc_malloc in stead of
4323 * gc-segment.c (scm_i_get_new_heap_segment): remove cluster cruft:
4324 only use SCM_MIN_HEAP_SEG_SIZE.
4326 * ports.c (scm_add_to_port_table): add backwards compatibility
4329 * ports.h: use scm_i_ prefix for port table and port table size.
4331 2002-08-15 Mikael Djurfeldt <mdj@linnaeus>
4333 * vports.c (scm_make_soft_port): Initialize pt variable.
4335 2002-08-13 Marius Vollmer <mvo@zagadka.ping.de>
4337 * strports.h (scm_c_eval_string_in_module,
4338 scm_eval_string_in_module): New prototypes.
4339 * strports.c (scm_eval_string_in_module): New, but use

4342 (scm_eval_string): Implement using scm_eval_string_in_module.
4343 (scm_c_eval_string_in_module): New.
4344 Thanks to Ralf Mattes for the suggestion!
4346 2002-08-09 Han-Wen Nienhuys <hanwen@cs.uu.nl>
4348 * gc-card.c ("sweep_card"): remove SCM_MISC_ERROR messages: print
4351 * gc-mark.c ("scm_gc_mark_dependencies"): idem.
4353 * ports.c ("scm_new_port_table_entry"): return a boxed SCM in
4354 stead of scm_t_port*. The function now takes a tag argument.
4356 2002-08-08 Han-Wen Nienhuys <hanwen@cs.uu.nl>
4358 * gc.h: add scm_debug_cells_gc_interval to public interface
4360 * gc-card.c ("sweep_card"): set scm_gc_running while sweeping.
4362 * gc.c (scm_i_expensive_validation_check): separate expensive
4363 validation checks from cheap ones.
4365 2002-08-06 Han-Wen Nienhuys <hanwen@cs.uu.nl>

4372 2002-08-05 Han-Wen Nienhuys <hanwen@cs.uu.nl>
4374 * tags.h: remove GC bits documentation from the tags table.
4376 * read.c (INPUT_ERROR): Prepare for file:line:column error
4377 messages for errors in scm_lreadr() and friends.
4379 2002-08-04 Han-Wen Nienhuys <hanwen@cs.uu.nl>
4381 * gc-malloc.c (scm_malloc): use scm_realloc() (simplifies
4383 (scm_gc_calloc): new function
4385 2002-08-04 Han-Wen Nienhuys <hanwen@cs.uu.nl>
4387 * ports.c (scm_new_port_table_entry): init port entry to 0
4390 * ports.c (scm_new_port_table_entry): change function from
4391 scm_add_to_port_table. This prevents cells with null-pointers from
4392 being exposed to GC.
4394 * vports.c (scm_make_soft_port) strports.c (scm_mkstrport),
4395 fports.c (scm_fdes_to_port): Use scm_new_port_table_entry().
4397 * gc.c (scm_gc_stats): add cell-yield and malloc-yield statistic
4400 * numbers.c (big2str): return "0" for 0 iso. ""
4402 * gc-segment.c, gc-malloc.c gc-mark.c, gc-freelist.c, gc-card.c,
4403 private-gc.h: new file
4405 * gc.c: completely revised and cleaned up the GC. It now uses lazy
4406 sweeping. More documentation in workbook/newgc.text
4408 2002-07-25 Marius Vollmer <marius.vollmer@uni-dortmund.de>
4410 * random.c (rstate_free): Return zero.
4412 2002-07-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
4414 * environments.c (remove_key_from_alist): Removed.
4416 (obarray_remove): Simplified.
4418 2002-07-24 Stefan Jahn <stefan@lkcc.org>
4420 * continuations.h: ia64: Include <signal.h> before
4423 2002-07-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
4425 * modules.c (scm_sym2var): Don't compare SCM values with ==.
4427 2002-07-21 Han-Wen Nienhuys <hanwen@cs.uu.nl>
4429 * goops.c (scm_compute_applicable_methods): use
4430 scm_remember_upto_here_1 iso scm_remember_upto_here
4432 * macros.c: include deprecation.h
4434 * vectors.c (scm_vector_move_right_x): remove side effect in
4436 (scm_vector_move_left_x): idem.
4438 * net_db.c, posix.c, socket.c: variable naming: change ans to
4441 * sort.c (scm_merge_vector_x): accept vector as argument
4442 iso. SCM*. This is needed for full GC correctness.
4444 * gc.h: undo previous undocumented changes related to #ifdef
4447 2002-07-20 Han-Wen Nienhuys <hanwen@cs.uu.nl>
4449 * *.c: add space after commas everywhere.
4451 * *.c: use SCM_VECTOR_SET everywhere, where a vector is written.
4452 Document cases where SCM_WRITABLE_VELTS() is used.
4454 * vectors.h (SCM_VELTS): prepare for write barrier, and let
4455 SCM_VELTS() return a const pointer
4456 (SCM_VECTOR_SET): add macro.
4458 2002-07-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
4460 * eval.c (SCM_CEVAL), macros.c (macro_print, scm_makmacro,
4461 scm_sym_macro, scm_macro_type), macros.h (scm_makmacro):
4462 Deprecated the special kind of built-in dynamic syntax transformer
4463 that was inaccurately named "macro". Note: The built-in syntax
4464 transformers that are named "mmacro" or "memoizing-macro" still
4465 exist, and it is these which come much closer to what one would
4468 2002-07-13 Neil Jerram <neil@ossau.uklinux.net>
4470 * eval.c (unmemocopy): Fix for
4471 1001-local-eval-error-backtrace-segfaults (unmemoization crash
4472 with internal definitions and local-eval).
4474 2002-07-12 Gary Houston <ghouston@arglist.com>
4476 * dynl.c: Don't define stub procedures if DYNAMIC_LINKING is not
4477 defined. They don't do anything useful, especially since the
4478 only case where DYNAMIC_LINKING is undefined seems to be
4479 when --with-modules=no is given to configure, which is basically
4480 requesting that the "dynamic linking module" be omitted.
4482 * Makefile.am (libguile_la_SOURCES): move dynl.c from
4483 libguile_la_SOURCES to EXTRA_libguile_la_SOURCES.
4485 * extensions.c (load_extension): check DYNAMIC_LINKING for
4487 * init.c (scm_init_guile_1): check DYNAMIC_LINKING for
4488 scm_init_dynamic_linking.
4490 2002-07-10 Marius Vollmer <mvo@zagadka.ping.de>
4492 * guile.c, iselect.h, net_db.c, posix.c, socket.c: No need to
4493 check for Cygwin when including <winsock2.h>, this is already
4494 check for by configure. Thus, revert change from 2002-07-07.
4496 2002-07-10 Gary Houston <ghouston@arglist.com>
4498 * eq.c: include <string.h>
4499 * dynl.c: docstring editing.
4501 2002-07-09 Gary Houston <ghouston@arglist.com>
4503 * dynl.c (scm_dynamic_call): docstring editing.
4505 2002-07-08 Rob Browning <rlb@defaultvalue.org>
4507 * gc_os_dep.c: HURD fixes.
4509 2002-07-07 Marius Vollmer <mvo@zagadka.ping.de>
4511 Crosscompiling and Cygwin fixes by Jan Nieuwenhuizen. Thanks!
4513 * Makefile.am: Override default rule for c-tokenize.$(OBJECT);
4514 this should be compiled for BUILD host.
4515 Override default rule for
4516 guile_filter_doc_snarfage$(EEXECT); this should run on BUILD host.
4517 Add missing $(EXEEXT) to guile_filter_doc_snarfage invocation.
4518 (snarf2checkedtexi): Use GUILE_FOR_BUILD instead of preinstguile.
4520 * guile.c, iselect.h, net_db.c, posix.c, socket.c: Do not include
4521 <winsock2.h> on Cygwin even when we have it.
4523 2002-07-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
4525 * __scm.h (SCM_CAUTIOUS), eval.c (scm_eval_args, deval_args,
4526 SCM_CEVAL): Removed compile time option SCM_CAUTIOUS to clean up
4527 the code. Full number of arguments checking of closures is
4528 mandatory now. However, the option to disable the checking has
4529 most probably not been used anyway.
4531 2002-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
4533 * __scm.h (SCM_RECKLESS), backtrace.c (SCM_ASSERT), debug.c
4534 (scm_debug_options), eval.c (scm_lookupcar, scm_lookupcar1,
4535 scm_badargsp, SCM_CEVAL, SCM_APPLY, scm_map, scm_for_each),
4536 feature.c (scm_init_feature), gsubr.c (scm_gsubr_apply), numbers.c
4537 (scm_logand, scm_logior, scm_logxor, scm_i_dbl2big), srcprop.c
4538 (scm_source_properties, scm_set_source_properties_x,
4539 scm_source_property): Removed compile time option SCM_RECKLESS to
4540 clean up the code. Full number of arguments checking of closures
4541 is mandatory now. However, the option to disable the checking has
4542 most probably not been used anyway.
4544 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
4545 scm_source_property): Use !SCM_CONSP instead of SCM_NCONSP.
4547 2002-06-30 Gary Houston <ghouston@arglist.com>
4549 * dynl.c: Removed all SCM_DEFER_INTS/SCM_ALLOW_INTS, which won't
4550 do anything useful. Added a comment about need for a mutex if
4551 pre-emptive threading is supported.
4553 * posix.c (scm_convert_exec_args), dynl.c
4554 (scm_make_argv_from_stringlist): static procs: 1) renamed both to
4555 allocate_string_pointers. 2) simplified: don't reallocate the
4556 strings, just make an array of pointers 3) avoid memory leaks on
4557 error 4) let the procedure report errors in its own name.
4558 Consequences: 1) the procedures now assume that SCM strings are
4559 nul-terminated, which should always be the case. 2) Since strings
4560 are not reallocated, it's now possible for strings passed to
4561 dynamic-args-call to be mutated.
4563 2002-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
4565 * __scm.h, eval.c, eval.h: Removed compile time option
4566 MEMOIZE_LOCALS to clean up the code. Now, caching of local
4567 variable positions during memoization is mandatory. However, the
4568 option to disable the caching has most probably not been used
4571 2002-06-18 Marius Vollmer <mvo@zagadka.ping.de>
4573 * print.c (scm_simple_format): Print missing part of format before
4574 ~% control. Thanks to Daniel Skarda!
4576 2002-06-01 Marius Vollmer <mvo@zagadka.ping.de>
4578 * mkstemp.c: Added exception notice to license statement.
4580 2002-05-22 Marius Vollmer <mvo@zagadka.ping.de>
4582 * numbers.c (mem2ureal): When returning an inexact zero, make sure
4583 it is represented as a floating point value so that we can change
4586 From John W. Eaton <jwe@bevo.che.wisc.edu>
4588 * numbers.c (idbl2str): Don't omit sign when printing negative zero.
4590 2002-05-14 Thien-Thi Nguyen <ttn@giblet.glug.org>
4592 * gc_os_dep.c: For I386/OPENBSD, allow for `__i386__'
4593 in addition to `i386'. Thanks to Dale P. Smith.
4595 2002-05-08 Marius Vollmer <mvo@zagadka.ping.de>
4597 * eq.c (real_eqv): New.
4598 (scm_eqv_p): Use it when comparing reals and complexes.
4600 * numbers.c: Include <string.h>, for strncmp.
4601 (mem2complex): Do not create negative NaNs.

4608 * posix.c (scm_putenv): Handle removing variables explicitely by
4613 * numbers.h: Conditionally include floatingpoint.h, ieeefp.h, and
4614 nan.h. Provide declarations for scm_inf_p, scm_nan_p, scn_inf,
4616 * numbers.c: [SCO && ! HAVE_ISNAN] (isnan): New function.
4617 [SCO && ! HAVE_ISINF] (isinf): New function.
4618 (xisinf, xisnan): New functions.
4620 (isfinite): Define in terms of xisinf.
4621 (scm_inf_p, scm_nan_p): New functions.
4622 (guile_Inf, guile_NaN): New file-scope vars.
4623 (guile_ieee_init): New function.
4624 (scm_inf, scm_nan): New functions.
4625 (idbl2str): Handle Inf and NaN. Remove funny label and
4626 corresponding gotos.
4627 (ALLOW_DIVIDE_BY_ZERO): New macro.
4628 (scm_divide): Allow division by zero to occur if
4629 ALLOW_DIVIDE_BY_ZERO is defined.
4630 Handle bignums and ints as special cases.
4632 Additional stuff by me:
4634 numbers.c (mem2ureal): Recognize "inf.0" and "nan.xxx".
4635 (scm_even_p, scm_odd_p): Treat infinity as even and odd.
4636 (iflo2str): Don't output a '+' for negative numbers or for Inf and
4637 NaN. They will provide their own sign.
4638 (scm_divide): Only allow divides by inexact zeros. Dividing by
4639 exact zeros still signals an errors.
4641 2002-04-22 Thien-Thi Nguyen <ttn@giblet.glug.org>
4643 * goops.h (scm_slot_exists_p): Rename from scm_slots_exists_p.
4644 * goops.c (scm_slot_exists_p): Rename from scm_slots_exists_p.

4665 2002-04-16 Marius Vollmer <mvo@zagadka.ping.de>
4667 * guile-snarf.in: Do not clean input file. This would write to
4668 the $(srcdir) during a VPATH build, which is not allowed. It also
4669 isn't needed since it only works when an output filename has been
4670 specified and in that case we don't need to clean the input file
4671 because the output file will already exist.
4673 2002-03-31 Marius Vollmer <mvo@zagadka.ping.de>

4710 stdout. When no "-o" option is given, use "-" as the output
4711 filename (i.e., stdout). Only 'clean' the inputfile or remove the
4712 output file on error when the output file name is not "-". Define
4713 the preprocessor macro SCM_MAGIC_SNARFER while snarfing.
4715 * Makefile.am (.c.x): Pass "-o $@" to guile-snarf.

4730 * eval.c (SIDEVAL): Removed.
4732 (SCM_CEVAL): Minimized scope of variable orig_sym. Eliminated
4733 goto-labels cdrxnoap, cdrxbegin and nontoplevel_cdrxnoap. Changed

4821 * eval.c (SCM_CEVAL): Got rid of the last reference to t.lloc.
4822 The next step will be to remove the union 't' and simplify the
4823 code of SCM_CEVAL that way.
4825 2002-03-12 Neil Jerram <neil@ossau.uklinux.net>
4827 * iselect.c (collisionp, gnfds, greadfds, gwritefds, gexceptfds,

4854 arg2. Removed some uses of t.arg1, t.lloc and proc as temporary
4855 variables. Introduced temporary variables with hopefully
4856 descriptive names for clarification. Replaced SCM_N?IMP by a more
4857 explicit predicate in some places. Use SCM_INSTANCE_HASH instead
4858 of computing the expression explicitly. Eliminate now unused

4878 of SCM_MAX_FRAME_SIZE as a bit mask; it isn't used like this.
4880 * eval.c (SCM_CEVAL): Don't store scm_debug_eframe_size in
4881 debug.status. It isn't needed, and it can overflow the bits

5350 2001-11-21 Gary Houston <ghouston@arglist.com>
5352 * Makefile.am (OMIT_DEPENDENCIES): removed, since it seems to be
5353 obsolete. autogen.sh says:

5402 (SCM_MICRO_VERSION): renamed from SCM_GUILE_MICRO_VERSION.
5404 2001-11-18 Neil Jerram <neil@ossau.uklinux.net>
5406 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
5407 Rewrite docstrings without reference to substring-move-left/right,
5408 since the latter no longer exist.

5412 * eval.c: Removed bogus comment about acros.
5414 (scm_unmemocar): Use !SCM_CONSP instead of SCM_IMP.

5426 checking of the body to scm_m_body.
5428 (scm_m_do): Move comment to function header. Rename arg1 to
5429 binding. Made the code a bit easier to read.
5433 (iqq): Added a comment. Changed the depth parameter to
5434 unsigned. Use size_t for vector lengths. Make sure vector object
5435 is gc protected as long as its contents are read. Add some syntax
5436 checks. Get rid of unnecessary SCM_IMP test. Clean up the
5437 control structure a bit.
5439 (scm_m_delay): Added comment about the implementation of
5442 (scm_m_define): Add comment about guile's currying define
5443 syntax. Renamed 'proc' to 'name'. Eliminate dependency on macro
5444 DEBUG_EXTENSIONS. Simplified code a bit. Eliminate SICP code.
5446 (scm_m_letrec1): Removed. Part of the functionality is taken
5447 over by the new function 'transform_bindings'.
5449 (transform_bindings): New function. Takes over some of the
5450 functionality of removed function 'scm_m_letrec1', namely to split
5451 a list of bindings into a reversed list of variables and a list of
5454 (scm_m_letrec): Call 'transform_bindings'.
5456 (scm_m_let): Minimized scope of local variables. Renamed 'proc'
5457 to 'temp' and 'arg1' to 'binding'. Eliminated redundant SCM_NIMP

5478 Change @deffnx lines in docstrings to say {Scheme Procedure}
5479 rather than primitive or procedure.
5481 * posix.c (scm_execl), filesys.c (scm_close), unif.c
5482 (scm_array_set_x, scm_array_contents, scm_uniform_array_read_x,
5483 scm_bit_set_star_x, scm_bit_invert_x), ramap.c (scm_array_fill_x,
5484 scm_array_for_each, scm_array_index_map_x), vectors.c (scm_vector,

5493 scm_object_property, scm_set_object_property_x): Remove invalid
5494 @deffnx lines for corresponding procedure property primitives.
5496 These changes add a @deffnx C function declaration and function

5506 snarf-check-and-output-texi.
5508 * Makefile.am (guile-procedures.texi): New rule.
5509 (BUILT_SOURCES, guile.texi, guile-procedures.txt, CLEANFILES):
5510 Changed so that the last stage of doc snarfing is now performed
5511 twice, once to produce guile-procedures.txt for online help, and
5512 once to produce guile.texi for reference manual synchronization.
5514 2001-11-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
5516 * eval.c (RETURN): Wrap in do{}while(0) in order to make it
5517 safely usable as a single statement followed by a ';', for example
5520 (SCM_CEVAL, SCM_APPLY): Clean up code using 'RETURN'.
5522 2001-11-13 Neil Jerram <neil@ossau.uklinux.net>

5541 HAVE_LONG_LONGS): Define to "1" when defining them, to mirror what
5544 2001-11-12 Marius Vollmer <mvo@zagadka.ping.de>
5546 * numbers.c: Document macros to define when including
5547 num2integral.i.c. MAX_VALUE and MIN_VALU are no longer used, we
5548 now rely on SIZEOF_ macros that have been figured out at
5551 * num2integral.i.c: Adapt to new interface.
5552 (NUM2INTEGRAL): Test whether a fixnum can be represented in the
5553 target type by casting it and checking whether it is still the
5554 same. Do not try to handle bignums for integral types that are
5555 smaller than fixnums. When handling bignums, collect the
5556 magnituse first into a unsigned type, and correctly check for
5558 (INTEGRAL2BIG): Do not use MIN_VALUE explicitely by observing that
5559 only -MIN_VALUE can still be negative of all negative numbers (in
5562 * tags.h (SIZEOF_SCM_T_BITS): Define it appropriately.
5564 * __scm.h: Define HAVE_UINTPTR_T, HAVE_PTRDIFF_T and
5565 HAVE_LONG_LONG depending on whether their size is non-zero.

5577 * unif.c (scm_uniform_array_write), ports.c
5578 (scm_current_output_port, scm_force_output), dynwind.c
5579 (scm_dynamic_wind), scmsigs.c (scm_setitimer, scm_getitimer),
5580 filesys.c (scm_open, scm_lstat), struct.c
5581 (scm_make_struct_layout), random.c (scm_random,
5582 scm_random_solid_sphere_x, scm_random_hollow_sphere_x, strop.c
5583 (scm_i_index): Remove superfluous whitespace from end of docstring
5586 * filesys.c (scm_select), guardians.c (scm_guardian_greedy_p),

5591 (scm_hash_fold), ports.c (scm_port_for_each): Remove superfluous
5592 newline at end of docstrings.
5594 * modules.c (scm_set_current_module): Add missing newline to
5597 2001-11-07 Stefan Jahn <stefan@lkcc.org>
5599 * win32-socket.[ch]: New files. Defines Winsock-API error codes
5600 and makes them available through Guile. That is because the
5601 Winsock-API does not store its errors in `errno' and thus cannot
5602 return error messages via `strerror (errno)'.
5604 * socket.c (scm_init_socket): Initialize `win32-socket' part
5605 here under M$-Windows.
5607 * numbers.h: Added missing declaration of
5608 `scm_sys_check_number_conversions()'.
5610 * error.c: Local definition of SCM_I_STRERROR and SCM_I_ERRNO
5611 and use in `(strerror)' and `(system-error)'.
5613 * Makefile.am (EXTRA_libguile_la_SOURCES): Added
5614 `win32-socket.[ch]' to extra source and header files.
5616 2001-11-06 Marius Vollmer <mvo@zagadka.ping.de>
5618 * script.c (scm_shell_usage, scm_compile_shell_switches): Prepend
5619 a call to turn-on-debugging when --debug has been given instead of
5620 turning it on directly. Also, handle new `--no-debug' option,
5621 which might suppress the call to turn-on-debugging.
5623 2001-11-05 Stefan Jahn <stefan@lkcc.org>
5625 * struct.c (s_scm_struct_vtable_p): Corrected docstring.
5627 2001-11-04 Stefan Jahn <stefan@lkcc.org>
5629 * Makefile.am (libguile_la_LIBADD): Added $(THREAD_LIBS_LOCAL)
5630 here (was at guile_LDADD) which describes the dependency
5631 correctly and allows a clean build on Win32.
5633 * __scm.h (SCM_API): Follow-up patch. Renamed __FOO__ macros
5636 * __scm.h: USE_DLL_IMPORT indicates the usage of the DLL
5637 import macros for external libraries (libcrypt, libqthreads,
5638 libreadline and libregex).
5640 * coop-defs.h: Include <winsock2.h> for `struct timeval'.
5642 * posix.c (flock): Added support for flock() in M$-Windows.
5644 * guile.c (SCM_IMPORT): Follow-up patch. Use SCM_IMPORT instead
5647 * fports.c (getflags): Differentiate reading and writing pipes
5650 * filesys.c (S_IS*): Redefine all of the S_IS*() macros for
5653 * coop.c (coop_condition_variable_timed_wait_mutex): Use
5654 conditionalized error code if `ETIMEDOUT' is not available.
5655 (scm_thread_usleep): Remove bogus declaration of `struct timeval
5658 * numbers.c (PTRDIFF_MIN): Moved this definition where it actually
5659 belongs. That is because NO_PREPRO_MAGIC gets undefined after
5660 each inclusion of `num2integral.i.c'.
5661 (SIZE_MAX): Define NO_PREPRO_MAGIC if SIZE_MAX is undefined.
5663 2001-11-03 Marius Vollmer <mvo@zagadka.ping.de>
5665 * eval.c (scm_m_begin): Allow `(begin)`, with no subforms.
5666 (SCM_CEVAL): Evaluate an empty `begin' to SCM_UNSPECIFIED.
5668 2001-11-02 Mikael Djurfeldt <mdj@linnaeus>
5670 * print.c (scm_iprin1): Mark print state as revealed when
5671 dispatching to generic write or display.
5673 * unif.c (scm_ra2contig): Fixed memory overwrite bug.
5675 2001-11-02 Marius Vollmer <mvo@zagadka.ping.de>
5677 Support for native Win32. Thanks to Stefan Jahn!
5679 * Makefile.am: Add win32-uname.c, win32-uname.h, win32-dirent.c
5680 and win32-dirent.h to extra source and header files. These
5681 include the uname() and the POSIX dirent interface implementation
5682 for M$-Windows. Put `-no-undefined' into LDFLAGS to support
5683 linkers which do not allow unresolved symbols inside shared
5684 libraries. Corrected `guile_filter_doc_snarfage$(EXEEXT)'
5687 * __scm.h: Defined SCM_API. This macro gets prepended to all
5688 function and data definitions which should be exported or imported
5689 in the resulting dynamic link library in the Win32 port.
5691 * __scm.h, alist.h, arbiters.h, async.h, backtrace.h, boolean.h,
5692 chars.h, continuations.h, coop-defs.h, coop-threads.h,
5693 debug-malloc.h, debug.h, deprecation.h, dynl.h, dynwind.h,
5694 environments.h, eq.h, error.h, eval.h, evalext.h, extensions.h,
5695 feature.h, filesys.h, fluids.h, fports.h, gc.h, gdb_interface.h,
5696 gdbint.h, gh.h, goops.h, gsubr.h, guardians.h, hash.h, hashtab.h,
5697 hooks.h, init.h, ioext.h, iselect.h, keywords.h, lang.h, list.h,
5698 load.h, macros.h, mallocs.h, modules.h, net_db.h, numbers.h,
5699 objects.h, objprop.h, options.h, pairs.h, ports.h, posix.h, print.h,
5700 procprop.h, procs.h, properties.h, ramap.h, random.h, rdelim.h,
5701 read.h, regex-posix.h, root.h, rw.h, scmsigs.h, script.h, simpos.h,
5702 smob.h, socket.h, sort.h, srcprop.h, stackchk.h, stacks.h, stime.h,
5703 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5704 tags.h, threads.h, throw.h, unif.h, values.h, variable.h, vectors.h,
5706 Prefixed each each exported symbol with SCM_API.
5708 * continuations.c: Added comment about the use of the extern
5709 declarations of {get,set}context() functions used in the ia64 port.
5711 * continuations.h, gc.c: `__libc_ia64_register_backing_store_base'
5712 is meant to be a `unsigned long *'.
5714 * filesys.c: Include `direct.h' if possible. Use local
5715 `win32-dirent.h' for the native M$-Windows port. Define S_IS*()
5716 macros for M$-Windows. Implementation of `fstat_Win32()' which is
5717 able to differentiate between sockets and other file descriptors.
5718 Use this function as wrapper in `scm_fstat()'. Fixed typo in
5721 * fports.c: Include `io.h' is possible. Put `*fp' into referring
5722 statement block in `scm_fport_buffer_add()'.
5723 Some corrections in `getflags()'.
5725 * gdb_interface.h (GDB_INTERFACE): Also support __CYGWIN__.
5727 * guile.c: Make sure to define __SCM_IMPORT__ for shared library
5728 build on Win32. Disable preloaded symbols on Win2 platforms.
5730 * ioext.c, ports.c: Include `io.h' is possible.
5732 * mkstemp.c: Include `process.h' is possible.
5734 * net_db.c: Disable extern declaration of `h_errno' for __CYGWIN__,
5736 Put `scm_return_entry()' into HAVE_GETSERVENT conditional.
5738 * posix.c: Remove unnecessary dirent includes and defines. Include
5739 local `win32-uname.h' for MinGW. Extern declaration of
5740 `mkstemp()' for systems where it does not exists. Make
5741 `getlogin()' available on M$-Windows.
5743 * scmsigs.c: Made `usleep()' avalable on MinGW.
5745 * stime.c: On M$-Windows `tzname[]' is known to be `_tzname[]'.
5747 * win32-dirent.c: Include "win32-dirent.h", not "dirent.h".
5749 * win32-uname.c: Include "win32-uname.h", not "uname.h".
5751 2001-10-28 Mikael Djurfeldt <mdj@linnaeus>
5753 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write):
5754 Don't apply scm_uniform_vector_length on arrays.
5756 2001-10-14 Dirk Herrmann <D.Herrmann@tu-bs.de>
5758 * eval.c (scm_lookupcar, scm_m_letstar, scm_m_do, iqq,
5759 scm_m_define, scm_m_letrec1, scm_m_let, scm_m_expand_body,
5760 scm_macroexp, unmemocopy, scm_eval_args, scm_deval_args,
5761 SCM_CEVAL, scm_map, scm_init_eval): When building lists, prefer
5762 scm_list_<n> over scm_cons[2]?.
5764 (scm_unmemocar, scm_m_cond, scm_m_letstar, scm_m_letrec1,
5765 scm_m_let, scm_m_atbind, unmemocopy, SCM_CEVAL, SCM_APPLY): Use
5766 SCM_C[AD][AD]R instead of explicit form.
5768 (scm_m_set_x, scm_m_cond, scm_m_letstar, scm_m_do): Reordered
5769 comparison parameters.
5771 (scm_m_case, scm_m_cond, scm_m_letstar, scm_m_do, SCM_CEVAL): Use
5772 !SCM_NULLP instead of SCM_NIMP.
5774 (scm_m_case): Don't copy the form. Renamed proc to clause and
5775 minimized its scope. Renamed x to clauses. Removed side
5776 effecting operation from macro call.
5778 (scm_m_cond): Don't copy the form. Renamed arg1 to clause and
5779 minimized its scope. Renamed x to clauses. Minimized the scope
5780 of variable 'len'. Make sure the else clause is treated specially
5781 even in case of '=>' occurences. Don't change the else to #t in
5782 order to be able to distinguish this case in the evaluator. Leave
5783 type checking of the recipient to the evaluator.
5785 (scm_c_improper_memq): Made the comment somewhat clearer.
5787 (scm_m_lambda): Renamed proc to formals. Removed unnecessary
5788 test for SCM_IM_LET at the place of the formal parameters.
5789 Simplified the formal parameter checking.
5791 (scm_m_letstar): Added Comment. Renamed proc to bindings.
5792 Renamed arg1 to binding and minimized its scope. Eliminated
5793 unnecessary consing.
5795 (scm_m_do): Renamed proc to bindings. Minimized the scope of
5798 (build_binding_list): New static function.
5800 (unmemocopy): Don't use SCM_TYP7 on pairs (it's unclean).
5801 Further, split up the 'letrec' unmemoizing code to the
5802 corresponding parts for 'do', 'let' and 'letrec', adding comments
5803 to each form. Cleanup the handling of the do form (This removes
5804 some *real* code :-).
5806 (SCM_CEVAL): Removed side effecting operation from macro call.
5807 Handle the 'else clause of the 'cond form specially - the symbol
5808 'else is not replaced with #t any more.
5810 2001-10-14 Gary Houston <ghouston@arglist.com>
5812 * version.c (scm_version): use sprintf instead of snprintf,
5813 for portability. thanks to Bill Schottstaedt.
5815 2001-10-14 Mikael Djurfeldt <mdj@linnaeus>
5817 * read.c (scm_lreadr): When user-defined hash procedure returns
5818 SCM_UNSPECIFIED: Fall back to standard handling instead of raising
5819 an exception. (This prevents parsing of uniform vectors from
5820 interfering with parsing of numbers.)
5822 2001-10-13 Marius Vollmer <mvo@zagadka.ping.de>
5824 * numbers.c: Set NO_PREPRO_MAGIC when defining our version of
5825 PTRDIFF_MIN. Thanks to Ken Raeburn.
5827 2001-10-07 Marius Vollmer <mvo@zagadka.ping.de>
5829 * Makefile.am (EXTRA_libguile_la_SOURCES): Added "mkstemp.c".
5831 * eval.c (scm_m_atbind): First try to find the variable without
5832 defining it locally; when it has not been found, define it
5835 * modules.c (module_variable): Pass over variables that exist but
5838 2001-10-06 Marius Vollmer <mvo@zagadka.ping.de>
5840 * backtrace.c (display_backtrace_file_and_line): Only use
5841 scm_basename when POSIX support is compiled in. Thanks to Chris
5844 2001-10-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
5846 * numbers.c (mem2uinteger): Return number read so far when coming
5847 across a hexdigit after having read a # or if not reading a hex
5848 value. This will enable the calling code to correctly handle
5849 forms like 1e2. (The background is, that the exponent markers d,
5850 e and f are also hexdigits.) Thanks to Mikael Djurfeldt for
5851 providing this patch.
5853 (mem2complex): Fix erroneous double-negation. Now, numbers like
5854 1-i will be read correctly.
5856 2001-10-12 Mikael Djurfeldt <mdj@linnaeus>
5858 * debug.c (scm_mem_to_proc): Fixed typo in previous change.
5860 * validate.h (SCM_VALIDATE_DOUBLE_DEF_COPY): New macro.
5862 2001-10-12 Dirk Herrmann <D.Herrmann@tu-bs.de>
5864 * print.c (scm_print_state_vtable, print_state_pool):
5865 Initialize. These variables are now registered as gc roots.
5867 (scm_current_pstate): Update documentation.
5869 (scm_current_pstate, scm_make_print_state, scm_free_print_state,
5870 scm_prin1, scm_init_print): print_state_pool is registered as a
5871 gc root and thus does not need to be protected by a surrounding
5874 (make_print_state): The car of print_state_pool no longer holds
5875 the scm_print_state_vtable.
5877 (scm_current_pstate, scm_make_print_state, print_circref,
5878 scm_iprin1, scm_prin1, scm_iprlist): Prefer !SCM_<foo> over
5881 (scm_prin1): When building lists, prefer scm_list_<n> over
5884 (scm_iprlist): Removed a redundant SCM_IMP test.
5886 (scm_simple_format): Use SCM_EQ_P to compare SCM values.
5888 2001-10-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
5890 * debug.c (scm_make_iloc): Prefer !SCM_<foo> over SCM_N<foo>.
5892 (scm_memcons, scm_mem_to_proc): When building lists, prefer
5893 scm_list_<n> over scm_cons[2]?.
5895 (scm_mem_to_proc): Prefer SCM_CONSP over SCM_NIMP.
5897 (scm_procedure_name): Use SCM_CADR instead of explicit form.
5899 (debugobj_print): Coerce scm_intprint arg 1 to long, not int.
5900 Thanks to Rob Browning for the patch (see log entry 2001-09-21) -
5901 for some reason his patch didn't make it into the cvs.
5903 2001-10-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
5905 * numbers.c (mem2decimal_from_point): Cleaned up the parsing a
5906 little bit - should even be somewhat more accurate now.
5908 2001-10-08 Rob Browning <rlb@defaultvalue.org>
5910 * gc.c: support ia64 register backing store.
5911 (SCM_MARK_BACKING_STORE): new macro.
5913 * continuations.h: support ia64 register backing store.
5914 (struct scm_t_contregs): add ia64 register backing store.
5916 * continuations.c: support ia64 register backing store.
5917 (continuation_mark): mark ia64 register backing store.
5918 (continuation_free): free ia64 register backing store.
5919 (scm_make_continuation): capture ia64 register backing store.
5920 (copy_stack_and_call): copy ia64 register backing store.
5922 2001-10-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
5924 * hashtab.c (scm_hash_fn_create_handle_x): The result of assoc_fn
5925 is known to be #f if no entry is found. Thus, use !SCM_FALSEP
5926 instead of SCM_NIMP to test for that case.
5928 * strings.h (SCM_SET_STRING_LENGTH): Cast the length to
5929 scm_t_bits instead of long.
5931 2001-10-06 Marius Vollmer <mvo@zagadka.ping.de>
5933 * tags.h (SCM_T_BITS_MAX, SCM_T_SIGNED_BITS_MAX,
5934 SCM_T_SIGNED_BITS_MIN): New.
5935 * numbers.h (SCM_MOST_POSITIVE_FIXNUM, SCM_MOST_NEGATIVE_FIXNUM):
5936 Use them to make these macros computable by the preprocessor.
5938 * num2integral.i.c (INTEGRAL2NUM): Let the preprocessor test
5939 whether the integral type fits in a fixnum, not the compiler.
5940 This removes a spurious compiler warning. Also, honor the
5941 NO_PREPRO_MAGIC flag to suppress any preprocessor tests. This is
5942 needed for `long long's.
5944 * numbers.c: Define NO_PREPRO_MAGOC when including
5945 num2integral.c.i for `long long' and `signed long long'.
5947 2001-10-06 Mikael Djurfeldt <mdj@linnaeus>
5949 These changes fixes a race condition in the Guile coop - pthread
5952 * coop.c (mother_awake_p): New variable.
5953 (coop_create): Set mother_awake_p before creating or signalling
5954 mother; wait until mother is going to sleep before returning.
5955 (mother): Reset mother_awake_p before going to sleep.
5957 2001-10-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
5959 * options.c (protected_objects, scm_init_options): The content of
5960 protected_objects is now protected from garbage collection using
5961 scm_gc_register_root instead of scm_permanent_object.
5963 (get_option_setting): New static function that computes an option
5964 setting as it was formerly done in the function scm_options.
5966 (get_documented_option_setting): New static function that
5967 returns option documentation as it was formerly done in the
5968 function scm_options. Note that documentation C strings are no
5969 longer precomputed into SCM objects. Instead, they are converted
5970 into SCM strings every time get_documented_option_setting is
5973 (change_option_setting): New static functions that modifies the
5974 option setting as it was formerly done in the function
5975 scm_options. The function is now exception safe, i. e. won't
5976 cause a memory leak when interrupted. Further, only non-immediate
5977 option values are added to the protection list.
5979 (scm_options): This function now has only the purpose to dispatch
5980 to to get_option_setting, get_documented_option_setting or
5981 change_option_setting, depending on the arguments given to
5984 (scm_init_opts): Don't convert documentation C strings into SCM
5985 strings. Further, don't protect any object values: They _must_
5986 be immediate values, otherwise there is no guarantee that they
5987 have not been collected before anyway.
5989 * options.[ch] (scm_t_option): Made type unsigned, name into a
5990 constant char* and val into a scm_t_bits type.
5992 (scm_options, scm_init_opts): The number of options is guaranteed
5993 to be larger or equal to zero. Thus, the type is changed to
5996 2001-10-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
5998 * num2integral.i.c (NUM2INTEGRAL): Eliminated some warnings about
5999 testing an unsigned value for being >= 0.
6001 2001-10-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
6003 * numbers.h: Removed old comment about using SCM_CAR to access
6006 (SCM_MOST_POSITIVE_FIXNUM, SCM_MOST_NEGATIVE_FIXNUM): Make sure
6007 the return value is signed. Thanks to Brian Crowder for the bug
6010 (SCM_SRS): Avoid unnecessary casting and don't unpack input
6011 values. With this patch, SCM_SRS can be safely used for other
6012 types than scm_t_signed_bits. However, it should still better be
6013 an internal macro and thus be renamed to SCM_I_SRS.
6015 (SCM_MAKINUM, SCM_INUM): Use proper casting.
6017 2001-10-03 Gary Houston <ghouston@arglist.com>
6019 * continuations.h, unif.h: in the descriptions of the bit patterns
6020 of the heap cells, make bit 0 the least significant.
6022 2001-09-25 Thien-Thi Nguyen <ttn@glug.org>
6024 * chars.h (SCM_MAKE_CHAR): Use `scm_t_bits' instead of `intptr_t'.
6025 Thanks to Golubev I. N.
6027 2001-09-25 Gary Houston <ghouston@arglist.com>
6029 * ports.c (scm_drain_input): extended the docstring. thanks to
6030 Alex Schroeder and Thien-Thi Nguyen.
6032 2001-09-23 Mikael Djurfeldt <mdj@linnaeus>
6034 * validate.h (SCM_NUM2FLOAT, SCM_NUM2DOUBLE,
6035 SCM_VALIDATE_FLOAT_COPY, SCM_VALIDATE_DOUBLE_COPY): New
6036 macros. (The NUM names might soon change.)
6038 * numbers.h: Added missing declarations.
6040 2001-09-22 Mikael Djurfeldt <mdj@linnaeus>
6042 * Makefile.am: Distribute num2float.i.c.
6044 * num2float.i.c: New file, multiply included by numbers.c, used
6045 to "templatize" the float <-> num conversion routines.
6047 * numbers.c: New functions: scm_num2float, scm_float2num,
6048 scm_num2double, scm_double2num.
6050 2001-09-21 Rob Browning <rlb@defaultvalue.org>
6052 * .cvsignore: really add version.h
6054 * strings.h (SCM_SET_STRING_LENGTH): coerce "l" to a long.
6055 Otherwise it fails on the alpha. However, we might rather choose
6056 this size conditionally.
6058 * numbers.c (scm_gcd): change "k" to a long from an int.
6059 Otherwise it fails on the alpha. However, we might rather choose
6060 this size conditionally.
6062 * error.c (scm_wta): coerce char* to intptr_t before int
6065 * debug.c (debugobj_print): coerce scm_intprint arg 1 to long, not
6068 * chars.h (SCM_MAKE_CHAR): coerce value to intptr_t.
6070 2001-09-20 Mikael Djurfeldt <mdj@linnaeus>
6072 * numbers.c (scm_integer_expt): Accept inexact integer in second
6073 argument. (Thanks to Bill Schottstaedt.)
6075 2001-09-20 Rob Browning <rlb@defaultvalue.org>
6077 * .cvsignore: add version.h
6079 * versiondat.h.in: removed (obsolete).
6081 * version.h.in: renamed from version.h.
6082 (SCM_GUILE_MAJOR_VERSION): new public macro.
6083 (SCM_GUILE_MINOR_VERSION): new public macro.
6084 (SCM_GUILE_MICRO_VERSION): new public macro.
6086 * version.h: renamed to version.h.in.
6089 (scm_major_version): support integer *_VERSION macros.
6090 (scm_minor_version): support integer *_VERSION macros.
6091 (scm_micro_version): support integer *_VERSION macros.
6092 (scm_version): support integer *_VERSION macros.
6094 2001-09-20 Mikael Djurfeldt <mdj@linnaeus>
6096 * error.c, error.h: Made error keys globally accessible.
6097 Applications might want to test for these or use them in a direct
6100 * num2integral.i.c (NUM2INTEGRAL): Report an error when these
6101 routines are passed an inexact. This change in behavior is
6102 motivated by concordance with R5RS: It is more common that a
6103 primitive doesn't want to accept an inexact for an exact.
6105 2001-09-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
6107 The following patch partially undoes my patch from 2001-06-30,
6108 where I added the function scm_gc_mark_cell_conservatively. The
6109 function is buggy, since it breaks guile during conservative
6110 marking if a pointer on the stack points directly into the list of
6111 free cells on the heap: With conservative cell marking this will
6112 cause the whole free list to be scanned and marked - boom!
6114 * gc.c (allocated_mark, MARK, heap_segment,
6115 scm_gc_mark_cell_conservatively, scm_init_storage), gc.h
6116 (scm_gc_mark_cell_conservatively): Remove function
6117 scm_gc_mark_cell_conservatively and update the corresponding
6118 comments and uses accordingly. Thanks to Christopher Cramer for
6119 the patch. (Minor corrections by me.)
6121 2001-09-15 Gary Houston <ghouston@arglist.com>
6123 * root.h (scm_root_state): removed the continuation_stack and
6124 continuation_stack_ptr members, which have no apparent purpose.
6125 (scm_continuation_stack, scm_continuation_stack_ptr): #defines
6128 * root.c (root_mark), init.c (restart_stack, start_stack), gc
6129 (scm_igc): remove all references to contination_stack and
6130 continuation_stack_ptr, avoiding allocation of a vector and
6131 useless processing during gc.
6133 2001-09-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
6135 * guardians.c (tconc_t, t_tconc): Renamed tconc_t to t_tconc.
6137 (TCONC_IN): Make sure that the cell word 0 is initialized last.
6139 (guardians_t, t_guardians): Renamed guardians_t to t_guardians.
6141 (GUARDIAN, GUARDIAN_DATA): Renamed GUARDIAN to GUARDIAN_DATA.
6143 (guardian_apply, scm_get_one_zombie, scm_make_guardian,
6144 mark_and_zombify): Prefer !SCM_<foo> over SCM_N<foo>.
6146 2001-09-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
6148 * guardians.c (mark_dependencies_in_tconc,
6149 whine_about_self_centered_zombies, scm_init_guardians): Register
6150 the static global variable `self_centered_zombies' via
6151 scm_gc_register_root, to make some cdr-ing unnecessary.
6153 2001-09-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
6155 * backtrace.c (display_backtrace_file,
6156 display_backtrace_file_and_line): Use SCM_EQ_P when comparing SCM

6696 hold predefined symbols.
6698 (build_class_class_slots): Build the list using scm_list_n
6699 instead of cons. Also, slots are already created as lists, thus
6700 making a call to maplist unnecessary.

6803 2001-07-01 Marius Vollmer <mvo@zagadka.ping.de>
6805 * strports.c (scm_read_0str, scm_eval_0str): Call
6806 scm_c_read_string and scm_c_eval_string respectively, not
6807 themselves. Thanks to Dale P. Smith!
6809 2001-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
6811 * unif.c (scm_array_set_x): The variable args does not
6812 necessarily have to be a list. Further, got rid of a redundant
6815 2001-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
6817 * list.c (SCM_I_CONS): Make sure the cell type is initialized
6820 * gc.c (s_scm_map_free_list, scm_igc, scm_gc_sweep,
6821 init_heap_seg): Fixed signedness.
6823 (init_heap_seg): Replaced strange for-loop with a while loop.
6825 * weaks.h (WEAKSH, SCM_WEAKS_H): Rename <foo>H to SCM_<foo>_H.
6827 (SCM_WVECTP): Prefer !SCM_<pred> over SCM_N<pred>.
6829 The following patch adds conservative marking for the elements of
6830 free or allocated cells.
6832 * gc.c (allocated_mark, heap_segment): New static functions.
6834 (which_seg): Deleted, since the functionality is now provided by

6839 (MARK): If cell debugging is disabled, mark free cells
6842 (scm_mark_locations, scm_cellp): Extracted the search for the
6843 heap segment of a SCM value into function heap_segment.

6850 The following patch changes the representation of weak vectors to
6851 double cells instead of using an extension of the vector's
6854 * gc.c (MARK): Use SCM_SET_WVECT_GC_CHAIN instead of assigning to
6855 the result of SCM_WVECT_GC_CHAIN.
6857 (scm_gc_sweep): Weak vectors don't have extra fields any more.
6859 * weaks.c (allocate_weak_vector): New static function. It does
6860 not patch any previously created vector object during the
6861 construction of a weak vector, and thus doesn't need to switch
6862 off interrupts during vector creation.
6864 (scm_make_weak_vector, scm_make_weak_key_hash_table,
6865 scm_make_weak_value_hash_table, scm_make_doubly_weak_hash_table):

6868 * weaks.h (SCM_WVECT_TYPE, SCM_SET_WVECT_TYPE,
6869 SCM_SET_WVECT_GC_CHAIN): New macros. The weak vector subtype is
6870 now stored in the double cell.
6872 (SCM_IS_WHVEC, SCM_IS_WHVEC_V, SCM_IS_WHVEC_B, SCM_IS_WHVEC_ANY):
6875 (SCM_WVECT_GC_CHAIN): The weak objects are now chained together
6876 using an entry of the double cell.
6878 2001-06-30 Thien-Thi Nguyen <ttn@revel.glug.org>
6880 * stamp-h.in: bye bye
6882 2001-06-30 Marius Vollmer <mvo@zagadka.ping.de>
6884 * gh_eval.c (gh_eval_str): Use scm_c_eval_string instead of
6887 * load.c, load.h (scm_c_primitive_load,
6888 scm_c_primitive_load_path): New.
6890 * strports.c, strports.h (scm_c_read_string): Renamed from

6910 * strings.c: #include "libguile/deprecation.h".
6912 2001-06-27 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
6914 * read.c (scm_lreadr): When reading a hash token, check for a
6915 user-defined hash procedure first, so that overriding the builtin
6916 hash characters is possible (this was needed for implementing
6917 SRFI-4's read synax `f32(...)').
6919 * num2integral.i.c: Use scm_t_signed_bits instead of scm_t_bits,
6920 because the latter is unsigned now and breaks comparisons like
6921 (n < (scm_t_signed_bits)MIN_VALUE).
6923 2001-06-26 Neil Jerram <neil@ossau.uklinux.net>
6925 * eval.h, eval.c (scm_call_4): New function.
6927 * eval.c (SCM_APPLY, SCM_CEVAL, ENTER_APPLY): Call trap handlers
6928 directly rather than dispatching to them via scm_ithrow and a lazy

6936 procedures not being #f.
6938 2001-06-27 Michael Livshin <mlivshin@bigfoot.com>
6940 * Makefile.am (c-tokenize.c): add rule to generate it.
6941 (EXTRA_DIST): add c-tokenize.lex, so it gets distributed.
6943 filter-doc-snarfage.c: remove.
6945 2001-06-26 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
6947 * ports.c (scm_output_port_p): Use result of SCM_COERCE_OUTPORT.
6949 The following set of changes makes compiling Guile under various
6950 Windows compilers easier. Compilation under GNU systems should
6951 not be affected at all.
6953 Thanks to Stefan Jahn for all necessary information, patches and

6983 initialized statically. Initialize at runtime instead.
6985 * fports.c (write_all): ssize_t -> size_t.
6986 (fport_print): Conditionalize call to ttyname().
6987 (getflags): New function, compiled only under Windows.

7561 corresponds to the former situation that SCM_VOIDP_TEST was
7564 (SCM): Now defined as typedef struct scm_unused_struct * SCM;
7565 If this appears to be not ANSI compliant, we will change it to
7566 typedef struct scm_unused_struct { } * SCM;
7567 Thanks to Han-Wen Nienhuys for the suggestion.
7569 * unif.c (scm_array_set_x): Fix typing problem, and use
7570 SCM_UVECTOR_BASE instead of SCM_VELTS or SCM_CELL_WORD_1 when
7571 dealing with uniform vectors.

7576 (scm_igc): mark from them, too (precisely, not conservatively!).
7578 * root.h (scm_gc_registered_roots): new object in
7581 * hooks.c (scm_create_hook): call `scm_gc_protect_object' instead
7582 `scm_protect_object'. shouldn't call it at all, though, it seems.
7584 * gc.c (scm_[un]protect_object): deprecated.
7585 (scm_gc_[un]protect_object): new names for scm_[un]protect_object.
7586 (scm_gc_[un]register_root[s]): new.

7617 * unif.c (scm_make_ra, array_free), unif.h (SCM_ARRAY_DIMS):
7618 Changed use of scm_array->scm_array_t and
7619 scm_array_dim->scm_array_dim_t to enable build with
7620 --disable-deprecated.
7622 2001-05-24 Michael Livshin <mlivshin@bigfoot.com>
7624 The purpose of this set of changes is to regularize Guile's usage
7625 of ANSI C integral types, with the following ideas in mind:
7627 - SCM does not nesessarily have to be long.
7628 - long is not nesessarily enough to store pointers.
7629 - long is not nesessarily the same size as int.
7631 The changes are incomplete and possibly buggy. Please test on

7804 (SCM_BITS_LENGTH): new, is the bit size of scm_bits_t (i.e. of an
7806 (ifdef spaghetti): include sys/types.h and sys/stdtypes.h, if they

7856 New functions. They replace scm_make_gsubr and
7857 scm_make_gsubr_with_generic. The `make' variants only create the

7865 scm_make_subr_with_generic. The `make' variants only create the
7866 subr object, while the `define' variants also put it into the
7867 current module. Changed all callers.

7978 Merged from mvo-vcell-cleanup-1-branch.
7980 The concept of vcells has been removed from Guile. With it,
7981 explicit obarrays and associated operations are gone. Use
7982 hashtables instead of obarrays.
7984 Throughout: use scm_sym2var instead of scm_sym2vcell and treat
7985 result as variable instead of vcell. Glocs no longer point to a

8577 * socket.c (scm_fill_sockaddr): improve the argument validation.
8578 don't allocate memory until all args are checked. instead of
8579 unconditional memset of soka, try setting sin_len to 0 if
8580 SIN_LEN is defined. add support for AF_INET6. define FUNC_NAME.

8612 SCM_CRITICAL_SECTION_START/END.
8613 (SCM_REALLOW_INTS: Bug fix. Don't call
8614 SCM_THREAD_SWITCHING_CODE.
8615 (SCM_TICK): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS. Instead, use
8616 SCM_THREAD_SWITCHING_CODE directly.
8617 (SCM_ENTER_A_SECTION): Unconditionally use
8618 SCM_CRITICAL_SECTION_START/END. (was:
8619 SCM_DEFER_INTS/SCM_ALLOW_INTS when SCM_POSIX_THREADS defined).
8621 2001-04-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
8623 * __scm.h (SCM_CAREFUL_INTS, SCM_DEBUG_INTERRUPTS): Replaced the

8646 * init.c, goops.c, goops.h: Reverted change of 2001-03-29. (The
8647 goops module should be registered in order to work for an
8648 application which uses libguile statically linked.)

8676 current (non-)usage of "read only" strings.
8677 (scm_make_shared_substring): Clarify docstring by changing
8678 "semantics" to "arguments".

8795 mode, as suggested by Michael Livshin.
8797 2001-03-31 Michael Livshin <mlivshin@bigfoot.com>
8799 * backtrace.c (display_backtrace_body): since the `print_state'
8800 variable is not used (instead its data field is used directly as
8801 `pstate'), protect it from the hungry compiler optimizations.
8802 thanks to Bill Schottstaedt for the report.
8804 2001-03-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
8806 * gc.[ch] (scm_tc16_allocated): New type tag for allocated cells.
8807 It is only defined and used if guile is compiled with
8808 SCM_DEBUG_CELL_ACCESSES set to true. It's purpose is, to never
8809 let cells with a free_cell type tag be visible outside of the
8810 garbage collector when in debug mode.
8812 * gc.c (scm_debug_cell_accesses_p): Set to true as default.
8814 (scm_assert_cell_valid): Use a local static variable to avoid
8817 (MARK): Only check for rogue cell pointers in debug mode. Use
8818 scm_cellp for this purpose and place all checks for rogue pointers
8819 into that function. Further, since due to conservative scanning
8820 we may encounter free cells during marking, don't use the standard
8821 cell type accessor macro to determine the cell type.
8823 (scm_cellp): Check if the cell pointer actually points into a
8826 (scm_init_gc): Initalize scm_tc16_allocated.
8828 * gc.h (GCH): Renamed to SCM_GC_H.
8830 (SCM_VALIDATE_CELL): Enclose the expression in brackets. This
8831 might be unnecessary, but I feel better this way :-)
8833 (SCM_GC_CELL_TYPE): New macro.
8835 (SCM_SETAND_CDR, SCM_SETOR_CDR): Deprecated. These are not used
8836 in guile, and it is unlikely that they will be applied to real
8839 (SCM_SET_FREE_CELL_TYPE): Removed. It was not used.
8841 (SCM_GC_SET_ALLOCATED): New macro. Only non-empty if guile is
8842 compiled with SCM_DEBUG_CELL_ACCESSES set to true.
8844 (SCM_NEWCELL, SCM_NEWCELL2): Use of SCM_GC_SET_ALLOCATED will
8845 make sure that in debug mode no free cell will ever be visible
8846 outside of the garbage collector.
8848 2001-03-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
8850 * async.c (scm_asyncs_pending): Don't use != to compare SCM
8853 * async.c (scm_system_async), variable.c (scm_make_variable,

8857 Remove suspicious use of SCM_SLOPPY_CONSP.
8859 * eq.c (scm_equal_p), tags.h (SCM_ECONSP): Use SCM_CONSP instead
8860 of SCM_SLOPPY_CONSP. A sane compiler should be able to perform
8861 the corresponding optimization.
8863 * eval.c (iqq): Use proper type check.
8865 (scm_m_expand_body): Remove redundant type checks.
8867 (promise_print): Don't access promise cells as pairs.
8869 * eval.c (EVALCAR, iqq, scm_m_expand_body, scm_eval_args,
8870 scm_deval_args SCM_CEVAL), guardians.c (scm_guard), hashtab.c
8871 (scm_internal_hash_fold), print.c (scm_iprlist): Use !SCM_CELLP
8872 for SCM_NCELLP, !SCM_CONSP for SCM_NCONSP, !SCM_IMP for SCM_NIMP,
8873 !SCM_FALSEP for SCM_NFALSEP, !SCM_NULLP for SCM_NNULLP
8875 * eval.c (scm_m_define, scm_macroexp, SCM_CEVAL), print.c
8876 (scm_iprin1): Use new macro predicate and accessors.
8878 * eval.h (scm_tc16_macro): Removed declaration. It is declared
8881 * eval.h (EVALH), macros.h (MACROSH), ports.h (PORTSH), procs.h
8882 (PROCSH), tags.h (TAGSH), variable.h (VARIABLEH): Renamed to
8883 SCM_EVAL_H, SCM_MACROS_H, SCM_PORTS_H, SCM_PROCS_H, SCM_TAGS_H and
8884 SCM_VARIABLE_H. Even the macros that are used to inhibit
8885 including a header file twice should be in the SCM_ namespace.
8887 * fluids.c (scm_swap_fluids, scm_swap_fluids_reverse),
8888 properties.c (scm_primitive_property_ref,
8889 scm_primitive_property_del_x): Prefer stronger predicates like
8890 SCM_NULLP or SCM_FALSEP over SCM_IMP.
8892 * gc.c (MARK): Use proper macros to access procedure-with-setter
8893 cell elements and closure cell elements.
8895 (gc_sweep_freelist_finish, scm_gc_sweep, init_heap_seg): Don't
8896 access free cells as pairs.
8898 (scm_unprotect_object): scm_hashq_get_handle returns #f if
8899 no hashtab entry is found.
8901 * gc.c (scm_gc_sweep), ports.c (scm_close_port): Use new macro
8902 SCM_CLR_PORT_OPEN_FLAG.
8904 * guardians.c (TCONC_IN), print.c (scm_free_print_state): Don't
8905 use SCM_SET_C[AD]R for uninitialized cells.
8907 * hashtab.c (scm_hash_fn_get_handle): Use SCM_VALIDATE_VECTOR.
8908 If the hashtable has no slots, return #f instead of '(). This
8909 unifies the return value with most assoc-functions.
8911 (scm_hash_fn_ref): Use proper type check.
8913 (scm_hashq_get_handle, scm_hashv_get_handle, scm_hash_get_handle):
8914 Removed references to non-existing functions from documentation.
8916 * keywords.c (scm_keyword_dash_symbol): Use proper macros to
8917 access keyword cell elements.
8919 * macros.h (SCM_MACROP, SCM_MACRO_TYPE, SCM_MACRO_CODE): New
8922 * ports.h (SCM_CLR_PORT_OPEN_FLAG): New macro.
8924 * print.c (scm_iprlist): Added comment. Improved loop

8930 * smob.c (scm_markcdr): Don't access smob cells as pairs.
8932 * tags.h (SCM_SLOPPY_CONSP, SCM_SLOPPY_NCONSP): Deprecated.
8934 * throw.c (ACTIVATEJB, DEACTIVATEJB): Don't access jump buffer
8937 * variable.c (variable_print, variable_equalp, scm_variable_ref,
8938 scm_variable_set_x): Use proper macros to access variable cell
8941 (scm_variable_bound_p): Don't use SCM_NEGATE_BOOL.
8943 * variable.h (SCM_VARVCELL): Don't access variable cells as
8946 * vectors.c (scm_vector), weaks.c (scm_weak_vector): Simplified,
8947 added FIXME comment, removed register specifier.
8949 2001-03-29 Keisuke Nishida <kxn30@po.cwru.edu>
8951 * goops.c, goops.h (scm_init_oop_goops_goopscore_module): Deprecated.
8952 * init.c (scm_init_guile_1): Don't init goopscore module.
8954 2001-03-27 Marius Vollmer <mvo@zagadka.ping.de>
8956 * eval.c (SCM_APPLY): Check that arg1 is bound for scm_tc7_cxr.
8958 2001-03-27 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
8960 * strop.c (scm_string_to_list): Fixed docstring markup.
8961 (scm_string_upcase_x, scm_string_upcase, scm_string_downcase_x),
8962 (scm_string_downcase, scm_string_capitalize_x),
8963 (scm_string_capitalize): Rewrote and corrected docstrings.
8964 (scm_string_ci_to_symbol): Made docstring more explicit.

8968 * values.h (scm_values_vtable, SCM_VALUESP): Moved here so that
8970 (scm_call_with_values): Removed.
8971 * values.c (values_vtable, scm_values_vtable): Added "scm_" prefix
8972 so that it can be exported.
8973 (scm_call_with_values): Removed.
8975 * tags.h (SCM_IM_CALL_WITH_VALUES): New isym.
8976 * eval.c: Include "libguile/values.h"
8977 (scm_m_at_call_with_values, scm_sym_at_call_with_values):
8979 (unmemocopy, scm_ceval, scm_deval): Handle new isym.
8980 * eval.h (scm_sym_at_call_with_values, scm_m_at_call_with_values):
8981 New delcarations to support above change.
8983 * eval.c (scm_primitive_eval_x, scm_primitive_eval): Fix syntax
8984 errors with last change.
8986 2001-03-25 Marius Vollmer <mvo@zagadka.ping.de>
8988 * eval.c (scm_primitive_eval_x, scm_primitive_eval, scm_i_eval_x,
8989 scm_i_eval): Moved the application of the system transformer from
8990 scm_i_eval to scm_primitive_eval.

9289 macros removed in the change of 2000-03-09. (Don't really have a
9290 complete grasp of what they are for, but they seem to be necessary
9291 on Crays. This needs testing!) Thanks to Miroslav Silovic.

9347 * socket.c (scm_fill_sockaddr): don't allow buffer overflows when
9348 taking an unexpectedly large filename for an AF_UNIX socket from

9358 avoid leakage. use malloc, not scm_must_malloc.

9360 substitute. free the sockaddr structure before throwing an error.
9361 (scm_init_add_buffer): procedure removed, together with its static
9362 buffer scm_addr_buffer, which wouldn't be thread safe. instead,
9363 define a macro MAX_ADDR_SIZE and declare the buffer where needed.
9364 (scm_accept, scm_getpeername, scm_getsockname, scm_recvfrom,
9365 scm_sendto): use a local buffer instead of scm_addr_buffer.

9369 call to detect whether recvfrom could be bothered to set the address.

9425 existing one; use EVALCAR instead of SIDEVAL so that we can properly
9426 check for empty combinations; use SCM_EVALIM2 for the same reason
9427 in the non-toplevel loop.
9428 (nontoplevel_cdrxnoap, nontoplevel_cdrxbegin, nontoplevel_begin):
9429 New labels with the meaning of their non-"nontoplevel" partners,
9430 but they are used when it is known that the body is not evaluated at
9432 (scm_apply, scm_dapply): use SCM_EVALIM2 to get proper error
9433 reporting for empty combinations.
9435 2001-03-02 Keisuke Nishida <kxn30@po.cwru.edu>

9458 (scm_string_ci_geq_p), symbols.c (scm_symbol_p)
9459 (scm_symbol_to_string, scm_string_to_symbol): Changed use of @t{}
9460 to @code{} as the texinfo manual recommends, converted the
9461 examples to use a @lisp{}-environment.
9463 * strports.c (scm_eval_string): Cleaned up the docstring.
9465 * struct.c (scm_struct_p, scm_struct_vtable_p): Added texinfo

9485 2001-02-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
9487 * __scm.h (SCM_ASSERT_TYPE): Add missing macro parameter.
9488 (Obviously nobody compiles with SCM_RECKLESS defined...)
9490 * validate.h (SCM_ASSERT_RANGE): Use the argument number.
9492 2001-02-23 Mikael Djurfeldt <mdj@linnaeus.mit.edu>

9500 * numbers.c (scm_two_doubles, scm_sys_expt, scm_sys_atan2,
9501 scm_make_polar): Rename arguments `z1' and `z2' to `x' and `y',
9502 since use of `z' suggests that the arguments may be complex.
9504 * goops.c (scm_make), numbers.c (scm_sys_expt): Fix docstring
9507 2001-02-23 Neil Jerram <neil@ossau.uklinux.net>

9518 * goops.c (scm_add_method, DEFVAR): Use scm_eval instead of
9520 (make_class_from_template): Do not bother to set the current
9521 module around the call to DEFVAR, scm_eval takes care of that.
9522 (scm_init_goops): Make scm_module_goops and
9523 scm_goops_lookup_closure permanent objects.
9525 * eval.c (scm_ceval, scm_deval): When evaluating expressions on
9526 top level, create a fresh top-level environment for each
9527 expression instead of mutating the exisint frame. This is
9528 important when that frame is closed over.
9530 * numbers.c (s_scm_logior) [SCM_DIGSTOOBIG]: Also use
9531 SCM_DIGSPERLONG instead of DIGSPERLONG.
9533 2001-02-21 Marius Vollmer <mvo@zagadka.ping.de>
9535 * eval.c (scm_ceval, scm_deval): Check for wrong number of args
9536 before applying arrow procedure in `cond' and before applying
9537 receiver procedure in call-with-current-continuation.
9538 (scm_i_eval): Do not invoke scm_copy_tree in argument in SCM_XEVAL
9539 macro. The argument is expanded more than one time.
9541 * numbers.c (scm_logior) [SCM_DIGSTOOBIG]: Correctly use
9542 SCM_BIGDIG instead of BIGDIG. Thanks to Steven G. Johnson!
9544 2001-02-20 Marius Vollmer <mvo@zagadka.ping.de>

9661 2001-02-15 Marius Vollmer <mvo@zagadka.ping.de>
9663 * symbols.c (scm_mem2symbol): Put a empty statement after the

9666 2001-02-13 Marius Vollmer <marius.vollmer@uni-dortmund.de>
9668 * gc_os_dep.c: Do not include <linux/version.h>. It makes no
9669 sense to compile for a specific kernel version. Do not include
9670 <asm/signal.h> while defining __KERNEL__. This hack should no
9671 longer be needed and caused problems.
9673 2001-02-13 Marius Vollmer <mvo@zagadka.ping.de>
9675 * eval.c (scm_ceval, scm_deval): use `SIDEVAL' instead of
9676 SCM_CEVAL when evaluating subforms of `begin' forms. SCM_CEVAL
9677 can not deal with immediates.
9679 2001-02-12 Keisuke Nishida <kxn30@po.cwru.edu>
9681 * list.c (scm_list_copy): Validate the first argument.

9688 * modules.h. modules.c (scm_current_module_lookup_closure): New
9691 * eval.h (scm_primitive_eval, scm_primitive_eval_x): New
9693 (scm_i_eval, scm_i_eval_x, scm_eval, scm_eval_x): Changed argument
9694 names to better reflect their meaning.
9696 * eval.c (scm_ceval, scm_deval): Recognize when `begin' is being
9697 evaluated at top-level and synronize lookup closure before
9698 executing every subform.
9699 (scm_primitve_eval_x, scm_primitive_eval): New functions.
9700 (scm_eval_x, scm_eval): Reimplement in terms of
9701 scm_primitive_eval_x and scm_primitive_eval, respectively.
9703 2001-02-09 Marius Vollmer <mvo@zagadka.ping.de>
9705 * macros.c (scm_macro_name, scm_macro_transformer): Use
9706 SCM_SMOB_DATA instead of SCM_CDR. Provided by Martin Grabmueller.
9709 2001-02-10 Keisuke Nishida <kxn30@po.cwru.edu>
9711 * dump.c (scm_store_bytes): Store data size before data.
9712 (scm_restore_bytes): Restore data size. Takes a pointer to size.
9713 * dump.h (scm_restore_bytes): Updated.
9715 2001-02-09 Keisuke Nishida <kxn30@po.cwru.edu>
9717 * dump.c: Use double cells for update schedule.
9719 2001-02-08 Keisuke Nishida <kxn30@po.cwru.edu>
9721 * ports.c (scm_unread_char): Take an optional argument.
9723 2001-02-08 Marius Vollmer <marius.vollmer@uni-dortmund.de>
9725 * modules.h (scm_selected_module, scm_current_module): Renamed
9726 scm_selected_module to scm_current_module to synchronize Scheme
9728 (scm_select_module, scm_set_current_module): Likewise. Changed
9731 * ports.c (scm_port_for_each): Make a snapshot of the port table
9732 before iterating over it. The table might change while the user
9733 code is running. With the snapshot, the user can depend on the
9734 fact that each port that existed at the start of the iteration is
9735 encountered exactly once. (ice-9 popen) depends on this.
9737 2001-02-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
9739 * strings.h (SCM_STRING_MAX_LENGTH): New macro.
9741 * strings.c (scm_makstr, scm_take_str, scm_make_string): Added
9742 range checking for the size parameter. Thanks to Martin
9743 Grabmueller for the hint.
9745 (scm_makstr): Reordered string initialization to make interrupt
9746 deferring unnecessary.
9748 * vectors.c (scm_make_vector): Fixed range checking.
9750 2001-02-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
9752 * vectors.h (SCM_VECTOR_MAX_LENGTH): New macro.
9754 * vectors.c (scm_make_vector, scm_c_make_vector): Improved the
9755 checking of the size parameter for type correctness and valid
9756 range. Thanks to Rob Browning for reporting the problem. Instead
9757 of deferring interrupts, scm_remember_upto_here_1 is used.
9759 2001-02-05 Keisuke Nishida <kxn30@po.cwru.edu>
9761 * dump.c (scm_store_cell_object, scm_restore_cell_object): Removed.
9762 (scm_dump_cell_update): Removed.
9763 (scm_dump_update): Renamed from scm_dump_object_update.
9764 (scm_restore_string, scm_restore_bytes, scm_restore_word): Takes
9765 a pointer instead of returning a value.
9766 * keywords.c (keyword_undump): Updated.
9768 2001-02-05 Keisuke Nishida <kxn30@po.cwru.edu>
9770 * dump.c, dump.h: Modified a lot.

9781 * keywords.c (keyword_dump): Renamed from keyword_dealloc.
9782 (keyword_undump): Renamed from keyword_alloc.
9783 (scm_init_keywords): Set keyword_dump and keyword_undump.
9785 2001-02-03 Michael Livshin <mlivshin@bigfoot.com>
9787 * gc.c (DOUBLECELL_ALIGNED_P): new macro, a better-named analog of
9788 the deprecated SCM_DOUBLE_CELLP.
9790 * tags.h (SCM_DOUBLE_CELLP): deprecated.
9792 2001-02-02 Keisuke Nishida <kxn30@po.cwru.edu>
9794 * dump.c, dump.h: New files.
9795 * Makefile.am: Added dump.c, dump.h, dump.x, dump.doc.
9796 * init.c: #include "libguile/dump.h".
9797 (scm_init_guile_1): Call scm_init_dump.
9798 * smob.h (scm_smob_descriptor): New slots: dump_mark,
9799 dump_dealloc, dump_store, undump_alloc, undump_restore,
9801 * smob.c (scm_make_smob_type): Init the new slots.
9802 (scm_set_smob_dump, scm_set_smob_undump): New functions.

9864 The following patch was sent by Martin Grabmueller. It makes sure
9865 that in case of parameter errors the correct function name is
9866 shown, and that parameter types are only checked once.
9868 * strop.c (string_copy, string_upcase_x, string_downcase_x,
9869 string_capitalize_x): New functions. Each one performs the core
9870 functionality of the corresponding scm_* function.

9949 The remaining code is just a wrapper to do the parameter
9952 (scm_string_leq_p, scm_string_gr_p, scm_string_geq_p): Check the
9953 parameters and call string_less_p instead of scm_string_less_p.

10061 from Matthias Köppe:

10110 error if so. take one more optional argument `throw_p'.
10111 (scm_guard): depending on the value of `throw_p', return a boolean
10113 (scm_get_one_zombie): remove redundant property test.
10114 (guardian_t): represent the various (currently 3, I hope nothing
10115 more gets added) boolean fields as bit flags.
