1 2004-07-05 Marius Vollmer <marius.vollmer@uni-dortmund.de>
3 * boolean.h, boolean.c (scm_is_true, scm_is_false, scm_from_bool,
6 2004-06-27 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
8 * backtrace.c (display_expression, display_frame): Call
9 scm_i_unmemoize_expr for unmemoizing a memoized object holding a
10 single memoized expression.
12 * debug.c (memoized_print): Don't try to unmemoize the memoized
13 object, since we can't know whether it holds a single expression
16 (scm_mem_to_proc): Removed check for lambda expression, since it
17 was moot anyway. Whoever uses these functions for debugging
18 purposes should know what they do: Creating invalid memoized code
19 will cause crashes, independent of whether this check is present
22 (scm_proc_to_mem): Take the closure's code as it is and don't
23 append a SCM_IM_LAMBDA isym. To allow easier debugging, the
24 memoized code should not be modified.
26 * debug.[ch] (scm_unmemoize, scm_i_unmemoize_expr): Removed
27 scm_unmemoize from public use, but made scm_i_unmemoize_expr
28 available as a guile internal function instead. However,
29 scm_i_unmemoize_expr will only work on memoized objects that hold
30 a single memoized expression. It won't work with bodies.
32 * debug.c (scm_procedure_source), macros.c (macro_print), print.c
33 (scm_iprin1): Call scm_i_unmemocopy_body for unmemoizing a body,
34 i. e. a list of expressions.
36 * eval.c (unmemoize_exprs): Drop internal body markers from the
37 output during unmemoization.
39 * eval.[ch] (scm_unmemocopy, scm_i_unmemocopy_expr,
40 scm_i_unmemocopy_body): Removed scm_unmemocopy from public use,
41 but made scm_i_unmemocopy_expr and scm_i_unmemocopy_body available
42 as guile internal functions instead. scm_i_unmemoize_expr will
43 only work on a single memoized expression, while
44 scm_i_unmemocopy_body will only work on bodies.
46 2004-06-21 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
48 * eval.c (unmemoize_exprs): Handle semi-memoized code.
50 (scm_cons_source, scm_primitive_eval): Prefer higher level
51 predicate SCM_FALSEP over SCM_IMP.
53 2004-06-15 Rob Browning <rlb@defaultvalue.org>
55 * script.c (scm_shell_usage): minor phrasing change.
57 * gc_os_dep.c: update ifdefery for macosx.
58 (scm_get_stack_base): separate result initialization from
59 declaration to slience warnings with macosx and hp-ux using gcc
60 3.3. Thanks to Andreas Vögele.
62 2004-06-13 Han-Wen Nienhuys <hanwen@xs4all.nl>
64 * eval.c (unmemoize_exprs): use SCM_CONSP for the loop condition.
66 2004-06-06 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
68 * list.[ch] (scm_i_finite_list_copy): New internal function to
69 copy lists that are known to be finite (though not necessarily
72 * debug.c (scm_procedure_source): Don't have scm_unmemocopy treat
73 a closure's argument list like an expression of a body.
75 * eval.c (unmemoize_expression, unmemoize_exprs, unmemoize_and,
76 unmemoize_begin, unmemoize_case, unmemoize_cond, unmemoize_delay,
77 unmemoize_do, unmemoize_if, unmemoize_lambda, unmemoize_let,
78 unmemoize_letrec, unmemoize_letstar, unmemoize_or,
79 unmemoize_set_x, unmemoize_apply, unmemoize_atcall_cc,
80 unmemoize_at_call_with_values, unmemoize_future, sym_atslot_ref,
81 unmemoize_atslot_ref, sym_atslot_set_x, unmemoize_atslot_set_x,
82 unmemoize_builtin_macro): New static functions and symbols.
84 (scm_unmemocopy): Rewritten in terms of the above. scm_unmemocopy
85 now has a slightly different meaning: The memoized form that is
86 receives as its argument is now interpreted as a sequence of
87 expressions from a body.
89 (unmemocar, scm_unmemocar): Since the whole functionality of
90 unmemocar and scm_unmemocar is not needed any more, scm_unmemocar
91 has its old content back and is deprecated, while unmemocar has
96 (CEVAL): For unmemoizing a single expression, call
97 unmemoize_expression instead of scm_unmemocopy, which now expects
98 a sequence of body expressions. Eliminated unnecessary empty
99 environment frame when executing let* forms. Eliminated
100 unmemoization step from evaluator.
102 2004-06-02 Marius Vollmer <marius.vollmer@uni-dortmund.de>
104 * eval.c (scm_macroexp, macroexp): Renamed scm_macroexp to
105 macroexp and made static. Added new version of scm_macroexp that
106 emits a deprecation warning and then calls macroexp.
107 (scm_m_undefine): Issue deprecation warning.
109 2004-05-30 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
111 * eval.c (lookup_global_symbol, literal_p, try_macro_lookup):
112 Modified to make set! work on symbols that represent syntactic
115 2004-05-26 Han-Wen Nienhuys <hanwen@xs4all.nl>
117 * gc.h (SCM_CELL_OBJECT_LOC): use SCM_GC_CELL_OBJECT to prevent
118 compound expression as lvalue errors.
120 2004-05-24 Marius Vollmer <mvo@zagadka.de>
122 * dynwind.c (winder_mark): Use SCM_PACK to correctly convert the
123 WINDER_DATA to a SCM.
125 2004-05-24 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
127 * goops.c (compute_getters_n_setters, create_standard_classes,
128 scm_add_slot): Compute closures by calling scm_i_eval_x on a
129 lambda expression rather than creating them with scm_closure.
131 2004-05-22 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
133 * eval.c (s_macro_keyword, scm_m_set_x): Remove checking for
134 misplaced syntactic keywords. This will not work unless guile's
135 defmacro feature is deprecated.
137 (scm_m_case): Fixed a bug that caused the list of labels to grow
138 with every case form.
140 2004-05-19 Kevin Ryde <user42@zip.com.au>
142 * numbers.c (scm_round_number): For inum and big, just return x. For
143 real, use scm_round for 2^54-1 etc problems covered there.
145 * numbers.c (trunc): Remove #define to scm_truncate when the C library
146 doesn't provide trunc. This was for when `truncate' was done as a
147 scm_tc7_dsubr, no longer required.
149 * threads.c (scm_threads_mark_stacks) [SCM_STACK_GROWS_UP]: Correction
150 to stack marking call, two parameters and no cast on t->base.
152 2004-05-18 Marius Vollmer <mvo@zagadka.de>
154 * hashtab.c (rehash_after_gc): Bug fix: properly link the
155 processed hashtables back into the weak_hashtables list. Thanks
156 to Bill Schottstaedt!
158 2004-05-16 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
160 * eval.c (unmemoize_quote): New static function.
162 (scm_m_quote, scm_m_atslot_ref, SCM_CEVAL): Changed the byte code
163 representation of 'quote' and '@slot-ref' to an improper list.
164 This reduces execution time, the number of cells used to hold the
165 memoized code, and thus also reduces garbage collection time.
167 (scm_unmemocopy): Use unmemoize_quote for quote expressions.
169 (SCM_CEVAL): Changed macro handling to also work with macros that
170 return improper lists. Added an assertion, that the code returned
171 by a macro transformer will not lead to cycles in the memoized
174 2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
176 No functional change, just rearrangements of functions within the
179 * eval.c (scm_ilookup, scm_unbound_variable_key,
180 error_unbound_variable, scm_lookupcar1, scm_lookupcar): Moved to
181 the definitions used for execution, since that's where they will
184 2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
186 * numbers.h (SCM_SLOPPY_FRACTIONP): Removed. It was not used
187 throughout guile, has not been part of an official release yet,
188 and the concept of sloppy predicates has never been a good idea.
190 (SCM_FRACTION_NUMERATOR, SCM_FRACTION_DENOMINATOR,
191 SCM_FRACTION_SET_NUMERATOR, SCM_FRACTION_SET_DENOMINATOR):
194 2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
196 * throw.c (SETJBJMPBUF, SCM_SETJBDFRAME): Add cast to scm_t_bits
197 to make explicit what happens.
199 2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
201 * dynl.c (SET_DYNL_HANDLE): Add cast to scm_t_bits to make
202 explicit what happens.
204 * guardians.c (TCONC_IN): Use SCM_SET_CELL_OBJECT_x rather than
205 SCM_SET_CELL_WORD_x when writing scheme objets to cell elements.
207 2004-05-11 Marius Vollmer <mvo@zagadka.de>
209 * scmsigs.c (scm_sigaction_for_thread): Validate that the handler
210 is indeed a procedure when it isn't a number.
212 2004-05-10 Marius Vollmer <mvo@zagadka.de>
214 Convert floating point numbers into strings with an arbitrary
215 radix. Thanks to Richard Todd!
217 * numbers.c (FLOBUFLEN): Increase so that radix 2 strings will
220 (scm_dblprec, fx_per_radix, init_dblprec, init_fx_radix,
221 number_chars): New, to support variable radices.
222 (idbl2str): Use above instead of the old base-10 only tables.
223 (iflo2str): Pass on new RADIX argument to idbl2str.
224 (scm_number_to_string): Pass radix to iflo2str.
225 (scm_print_real, scm_print_complex): Explicitly pass radix 10 to
227 (scm_init_numbers): Call init_dblprec and init_fx_radix for all
230 2004-05-10 Kevin Ryde <user42@zip.com.au>
232 * numbers.c (scm_logbit_p): Correction to test above the end of an
233 inum. Reported by Jan Konecny.
235 2004-05-06 Marius Vollmer <marius.vollmer@uni-dortmund.de>
237 * gc.h (scm_t_cell): Fields are now of type SCM instead of
238 scm_t_bits. Updated all users.
239 (SCM_GC_CARD_SIZE_MASK): Use SCM_GC_SIZEOF_CARD instead of
240 duplicating the code.
241 (SCM_CELL_OBJECT_LOC): New.
242 (SCM_CARLOC, SCM_CDRLOC): Use it instead of SCM_CELL_WORD_LOC.
243 (SCM_CELL_WORD_LOC): Moved to "deprecated.h".
245 * smob.h (SCM_SMOB_DATA_2, SCM_SMOB_DATA_3, SCM_SMOB_FLAGS,
246 SCM_SET_SMOB_DATA_2, SCM_SET_SMOB_DATA_3, SCM_SET_SMOB_FLAGS,
247 SCM_SMOB_OBJECT, SCM_SMOB_OBJECT_2, SCM_SMOB_OBJECT_3,
248 SCM_SET_SMOB_OBJECT, SCM_SET_SMOB_OBJECT_2, SCM_SET_SMOB_OBJECT_3,
249 SCM_SMOB_OBJECT_LOC, SCM_SMOB_OBJECT_2_LOC,
250 SCM_SMOB_OBJECT_3_LOC): New.
251 * smob.c (scm_i_set_smob_flags): New function.
253 * dynl.c, dynwind.c, eval.h, fluids.h, futures.h, hashtab.h,
254 hooks.h, keywords.h, macros.h, macros.c, mallocs.c, mallocs.h,
255 random.h, regex-posix.h, root.h, srcprop.h, srcprop.c, threads.h:
256 Use SCM_SMOB_* instead of SCM_CELL_* as appropriate. Use
257 SCM_SMOB_FLAGS and SCM_SET_SMOB_FLAGS instead of accessing the
258 zeroth word directly. Use SCM_SMOB_PREDICATE as appropriate.
260 * numbers.h (SCM_I_BIG_MPZ): Use SCM_CELL_OBJECT_LOC instead of
261 taking the address of SCM_CELL_WORD_1, the latter being no longer
264 * variable.h (SCM_VARIABLE_LOC): Use SCM_CELL_OBJECT_LOC instead
265 of casting SCM_CELL_WORD_LOC.
267 2004-05-02 Kevin Ryde <user42@zip.com.au>
269 * eval.c (scm_macroexp): Add prototype, since it's not in eval.h under
270 --disable-deprecated. Reported by Andreas Vögele.
272 * filesys.c (_POSIX_C_SOURCE): Define to 199506L to get readdir_r (in
273 particular on HP-UX). Reported by Andreas Vögele.
275 * list.c (varargs.h): Remove, leave just stdarg.h which is all the
276 code has support for. Fixes building with AIX cc, which is ansi but
277 doesn't define __STDC__. Reported by Keith Crane.
278 (var_start): Remove macro, this variation no longer required.
279 (scm_list_n): Use va_start directly.
281 2004-05-01 Kevin Ryde <user42@zip.com.au>
283 * continuations.c (scm_dynthrow): Use >= instead of SCM_PTR_GE which
284 is now gone. Reported by Andreas Vögele.
286 2004-04-28 Kevin Ryde <user42@zip.com.au>
288 * backtrace.c (display_frame_expr), numbers.c (XDIGIT2UINT,
289 mem2uinteger, mem2decimal_from_point, mem2ureal): Cast char to int for
290 ctype.h tests, to avoid warnings from gcc on HP-UX about char as array
291 subscript. Reported by Andreas Vögele.
292 Also cast through unsigned char to avoid passing negatives to those
293 macros if input contains 8-bit values.
295 * num2integral.i.c (NUM2INTEGRAL): Under non-BIGMPZ_FITSP case,
296 corrections to range check for signed numbers. Remove
297 scm_remember_upto_here_1(num) from these checks, since num is used
300 * num2integral.i.c (NUM2INTEGRAL): Test BIGMPZ_FITSP with "!= 0" to
301 avoid warning from gcc 3.4. Reported by Hyperdivision.
303 * numbers.c (scm_bit_extract): Use min instead of MIN.
304 (MIN): Remove, this conflicts with similar macro defined by limits.h
305 on HP-UX. Reported by Andreas Vögele.
307 * stime.c (_POSIX_C_SOURCE): Define to 199506L to get gmtime_r (in
308 particular on HP-UX). Reported by Andreas Vögele.
310 * threads.c (scm_threads_mark_stacks): Correction sizet -> size_t.
311 Reported by Andreas Vögele.
313 * threads-plugin.h (SCM_MUTEX_MAXSIZE): Increase to 25*sizeof(long),
314 for the benefit of hpux11 where pthread_mutex_t is 88 bytes. Reported
317 2004-04-22 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
319 * eval.c (s_macro_keyword): New static identifier.
321 (scm_m_define): Change order to first create binding and
322 evaluating the expression afterwards.
324 (scm_m_set_x): Memoize complete set! expression. Only leave
325 symbols if no binding exists at memoization time. Throw error if
326 assigning to a syntactic keyword.
328 (lazy_memoize_variable): New function.
330 (CEVAL): When execution set!, perform lazy memoization if
331 unmemoized symbol is detected.
333 * modules.c (module_variable): Return variables with unbound
336 * tags.h: Fix comment.
338 2004-04-25 Kevin Ryde <user42@zip.com.au>
340 * chars.c (scm_char_upcase, scm_char_downcase, scm_c_upcase,
341 scm_c_downcase): Use ctype.h toupper and tolower. This will be useful
342 in 8-bit locales, and ensures consistency with char-upper-case? and
343 char-lower-case? which already use ctype.h.
344 (scm_c_upcase_table, scm_c_downcase_table, scm_lowers, scm_uppers):
346 * chars.c, chars.h, init.c (scm_tables_prehistory): Remove.
348 * socket.c (VALIDATE_INET6): Correction to bignum_in_ipv6_range_p
349 call. Reported by Hyperdivision.
351 * threads.c (scm_yield): Correction, actually call scm_thread_yield.
352 Reported by Hyperdivision.
354 * unif.c (s_scm_make_uve): Remove unused local variable. Reported by
357 2004-04-22 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
359 Hide the implementation of ilocs and isyms in eval.c.
361 * deprecated.h (SCM_IFRINC, SCM_ICDR, SCM_IFRAME, SCM_IDIST,
362 SCM_ICDRP), eval.c (SCM_IFRINC, SCM_ICDR, SCM_IFRAME, SCM_IDIST,
363 SCM_ICDRP), eval.h (SCM_ICDR, SCM_IFRINC, SCM_IFRAME, SCM_IDIST,
364 SCM_ICDRP): Deprecated and added to deprecated.h. Moved from
367 * deprecated.c (scm_isymnames), deprecated.h (scm_isymnames,
368 SCM_ISYMNUM, SCM_ISYMCHARS), eval.c (SCM_ISYMNUM, isymnames,
369 scm_unmemocopy, CEVAL), print.c (scm_isymnames), tags.h
370 (SCM_ISYMNUM, scm_isymnames, SCM_ISYMCHARS): Deprecated
371 scm_isymnames, SCM_ISYMNUM and SCM_ISYMCHARS and added to
372 deprecated.[hc]. Moved scm_isymnames from print.c to eval.c and
373 renamed to isymnames. Moved SCM_ISYMNUM from tags.h to eval.c and
376 * eval.c (scm_i_print_iloc, scm_i_print_isym), eval.h
377 (scm_i_print_iloc, scm_i_print_isym), print.c (scm_iprin1):
378 Extracted printing of ilocs and isyms to guile internal functions
379 scm_i_print_iloc, scm_i_print_isym of eval.c.
381 2004-04-22 Kevin Ryde <user42@zip.com.au>
383 * numbers.c (scm_bit_extract): Use SCM_SRS for signed right shift.
385 * numbers.c (scm_round): Test for x already an integer, to avoid bad
386 rounding in x+0.5 when x is a big value already an integer. In
387 certain hardware rounding cases x+0.5 can give an adjacent integer,
388 leading to that as the result, when we really just wanted x itself.
390 2004-04-19 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
392 * eval.c (scm_unmemocopy): Fixed unmemoization of let*.
394 (deval_args, CEVAL): Minor improvements: Reduced variable scopes,
395 added const qualifiers, cast intentionally unused expressions to
396 void for emphasis, improved comment.
398 2004-04-18 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
400 * tags.h (scm_tags, scm_tc8_tags, scm_tc9_flag, scm_tc8_flag,
401 scm_tc8_isym): Renamed scm_tags to scm_tc8_tags. Renamed
402 scm_tc9_flag to scm_tc8_flag. Introduced new identifier
403 scm_tc8_isym. Defined tc8-tags relative to scm_tc3_imm24.
404 Defined the tc8-tag for flags to be 0x04, which will mean that
405 SCM_BOOL_F will also have the value 0x04 instead of 0x013c. Due
406 to the reduced number of bits and the simpler bit pattern for
407 SCM_BOOL_F, certain machines may be able to use more efficient
408 processor instructions to deal with SCM_BOOL_F.
410 (SCM_ITAG9, SCM_MAKE_ITAG9, SCM_ITAG9_DATA): Removed. These have
411 never been defined in a released version, thus no need to
414 (SCM_IFLAGP, SCM_MAKIFLAG, SCM_IFLAGNUM): Flags now use tc8
417 (SCM_ISYMP, SCM_MAKISYM, SCM_ISYMNUM): Isyms now use tc8 instead
420 (SCM_MAKSPCSYM): Removed. It is almost impossible that user code
421 could have used this definition.
423 (SCM_IM_AND, SCM_IM_BEGIN, SCM_IM_CASE, SCM_IM_COND, SCM_IM_DO,
424 SCM_IM_IF, SCM_IM_LAMBDA, SCM_IM_LET, SCM_IM_LETSTAR,
425 SCM_IM_LETREC, SCM_IM_OR, SCM_IM_QUOTE, SCM_IM_SET_X): Now encoded
426 as isyms, as special isyms don't exist any more.
428 2004-04-18 Kevin Ryde <user42@zip.com.au>
430 * filesys.c (scm_readdir): Use readdir_r when available, for thread
433 * numbers.c (scm_max, scm_min): For big/real, use SCM_SWAP rather than
434 explicit swapping code.
436 2004-04-15 Kevin Ryde <user42@zip.com.au>
438 * cpp_sig_symbols.in: Add SIGSYS.
440 * list.c (scm_append_x): Use iterative style, to avoid non-tail
443 * numbers.c (scm_max, scm_min): For inum/frac, frac/inum, big/frac,
444 frac/big and frac/frac, use scm_less_p for exact comparison.
446 * numbers.c (scm_gcd): For inum/big, use mpz_gcd_ui by sharing code
449 * numbers.c (xisinf): Add a comment about solaris 7 lacking isinf.
451 2004-04-06 Han-Wen Nienhuys <hanwen@xs4all.nl>
453 * inline.h (scm_cell): use SCM_GC_CELL_WORD for checking tag.
455 * chars.h (scm_init_chars): change scm_{upcase,downcase} to
457 (SCM_MAKE_CHAR): add (unsigned char) cast. This prevents havoc
458 when hi-bit ASCII is subjected to SCM_MAKE_CHAR().
460 2004-04-06 Kevin Ryde <user42@zip.com.au>
462 * numbers.c (scm_ash): Remove stray "}" in docstring.
464 * numbers.c (scm_make_ratio): For inum/bignum integer detection, use
465 x==SCM_MOST_NEGATIVE_FIXNUM explicitly, for clarity and to avoid
466 calling mpz_cmp_ui in most cases.
468 * numbers.c (scm_quotient, scm_remainder): In inum/big, use mpz_cmp_ui
469 for big == abs(most-negative-fixnum) special case.
470 (abs_most_negative_fixnum): Remove, no longer used.
472 * scmsigs.c (scm_sigaction_for_thread): Correction to signum range
473 test, avoids SCM_VECTOR_REF outside bounds of signal_handlers on
474 calling (sigaction NSIG).
476 * simpos.c (scm_system_star): Fix execargv memory leak, merge parent
477 and fork error cases to do this.
479 2004-04-03 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
481 * eval.c (CEVAL): Don't distinguish between short and long
482 instructions when dispatching - just always dispatch on the
483 instruction code, which is common for short and long instructions.
484 Further, removed unnecessary goto statements and added comment.
486 2004-04-03 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
488 * eval.c (scm_unmemocopy): Don't distinguish between short and
489 long instructions when dispatching - just always dispatch on the
490 instruction code, which is common for short and long instructions.
491 Further, removed unnecessary goto statements, fixed indentation
492 and replaced SCM_IMP predicates by SCM_NULLP.
494 2004-04-03 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
496 * eval.c (scm_lookupcar1, CEVAL): Use SCM_ILOCP instead of
497 comparison with SCM_ILOC00. In CEVAL, eliminate goto-label
500 2004-03-31 Kevin Ryde <user42@zip.com.au>
502 * simpos.c: Include <signal.h> for SIG_IGN and friends.
504 2004-03-29 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
506 Introduce scm_debug_mode_p as a replacement for scm_debug_mode and
509 * debug.h (scm_debug_mode_p, scm_debug_mode, SCM_DEBUGGINGP),
510 eval.c (scm_debug_mode_p): Deprecated scm_debug_mode and
511 SCM_DEBUGGINGP. Provided scm_debug_mode_p instead, to have one
512 single interface that also matches the naming conventions.
513 Probably scm_debug_mode_p should be part of the private interface
516 * debug.h (scm_debug_mode_p), backtrace.c (display_error_body),
517 eval.c (SCM_APPLY, scm_trampoline_0, scm_trampoline_1,
518 scm_trampoline_2): Change uses of scm_debug_mode or SCM_DEBUGGINGP
522 Deprecate direct access to scm_ceval, scm_deval and scm_ceval_ptr:
524 * eval.h (scm_ceval, scm_deval, scm_ceval_ptr), debug.h
525 (scm_ceval_ptr): Deprecated. Moved declaration of scm_ceval_ptr
526 from debug.h to eval.h.
528 * debug.h (SCM_RESET_DEBUG_MODE): Don't access scm_ceval_ptr any
529 more, just leave it with setting scm_debug_mode_p, which is
530 equivalent for practical purposes.
532 * deprecated.h (SCM_XEVAL, SCM_XEVALCAR): Call scm_i_eval_x
533 instead of *scm_ceval_ptr. Leave all evaluating to scm_i_eval_x.
535 * gdbint.c (gdb_eval): Call scm_i_eval_x instead of scm_ceval.
537 * eval.c (ceval, deval, scm_ceval, scm_deval): Made scm_ceval
538 static and renamed it to ceval throughout. Provide a new exported
539 but deprecated function scm_ceval as a wrapper for backwards
540 compatibility. The same is done for the deval/scm_deval pair of
543 * eval.c (CEVAL, SCM_CEVAL): Renamed SCM_CEVAL to CEVAL
544 throughout. Defined CEVAL to ceval or deval, based on compilation
547 * eval.c (SCM_XEVAL, SCM_XEVALCAR): Dispatch on scm_debug_mode_p
548 to ceval and deval instead of calling *scm_ceval_ptr.
550 * eval.c (dispatching_eval): New deprecated static function.
552 * eval.c (scm_ceval_ptr): Initialized to dispatching_eval in order
553 to emulate its old behaviour as closely as possible.
556 Change the evaluator such that only expressions for which pair? is
557 true are passed to CEVAL, and such that all other expressions are
558 evaluated outside of CEVAL:
560 * eval.c (EVAL): New, provided in analogy to EVALCAR. Evaluate an
561 expression that is assumed to be memoized already. All but
562 expressions of the form '(<form> <form> ...)' are evaluated inline
563 without calling an evaluator.
565 * eval.c (SCM_XEVAL, SCM_XEVALCAR, EVALCAR): Evaluate all but
566 expressions of the form '(<form> <form> ...)' inline without
567 calling an evaluator.
569 * eval.c (scm_i_eval_x, scm_i_eval, scm_ceval, scm_deval): Handle
570 the special case of unmemoized symbols passed on the top level.
572 * eval.c (CEVAL): Change calls to CEVAL to EVAL, except where it
573 is known that the expression passed to CEVAL is of the form
574 '(<form> <form> ...)'. Remove handling of the tc7-objects, since
575 now it is known that the input expression of CEVAL is a pair.
577 2004-03-29 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
579 * eval.c (is_self_quoting_p): New static function.
581 (scm_m_quote): Use is_self_quoting_p.
583 (copy_tree): Corrected typo in comment.
585 2004-03-28 Han-Wen Nienhuys <hanwen@xs4all.nl>
587 * eval.c (s_scm_copy_tree): idem.
589 * list.c (s_scm_filter): remove "pointer" from doc string.
591 * gc.h (SCM_GC_CELL_TYPE): SCM_GC_CELL_TYPE uses SCM_GC_CELL_OBJECT.
593 * goops.h (SCM_NUMBER_OF_SLOTS): don't SCM_UNPACK the result.
595 * backtrace.c ("display_backtrace_body"): SCM_PACK before SCM_EQ_P
596 (display_frame): idem.
597 (display_backtrace_file_and_line): idem.
599 * tags.h (SCM_UNPACK): stricter typechecking on SCM_UNPACK
602 2004-03-26 Kevin Ryde <user42@zip.com.au>
604 * filesys.c (scm_getcwd, scm_readlink): Avoid memory leak on errors.
606 * numbers.c (scm_modulo): For inum/big and big/big, remove test of
607 big==0 since that never occurs.
609 * numbers.c, numbers.h (scm_modulo_expt): Renamed from
610 scm_modular_expt, matching scheme level name `modulo-expt'.
612 * numbers.c (scm_modular_expt): Return a negative remainder for a
613 negative divisor, the same as `modulo' does.
615 2004-03-26 Eric Hanchrow <offby1@blarg.net>
617 * numbers.c, numbers.h (scm_modular_expt): New function.
619 2004-03-25 Kevin Ryde <user42@zip.com.au>
621 * numbers.c (scm_min, scm_max): Correction to big/real and real/big,
622 return inexact as required by r5rs.
624 2004-03-24 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
626 * eval.c: Separated some definitions relevant for execution from
627 the memoization part of the file.
629 (copy_tree): New static function
631 (scm_copy_tree): Rewritten to fix two kinds or bugs: First, cyclic
632 structures are detected now and will lead to an exception instead
633 of forcing guile to run in an endless loop, using up all the
634 system's memory. Second, arrays in the cdr of an improper list
635 are now copied. See the new test cases in eval.test.
637 2004-03-24 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
639 * posix.c (scm_gethostname): Make sure len is initialised before
640 it is used. Restructured to (hopefully) represent possible
641 configurations more clearly in the code. Added unwind handler.
643 2004-03-23 Kevin Ryde <user42@zip.com.au>
645 * posix.c (scm_gethostname): Use sysconf(_SC_HOST_NAME_MAX) and/or
646 MAXHOSTNAMELEN when available.
648 2004-03-21 Marius Vollmer <mvo@zagadka.de>
650 * read.c (skip_scsh_block_comment): Also recognize '\r' as a line
651 terminator. Rewritten the logic as a state machine, I must have
652 been doing too much VHDL lately...
654 * eval.c (scm_ceval, scm_deval): Explicitely evaluate ports to
655 themselves. Thanks to Han-Wen Nienhuys!
657 * list.c: Changed docstrings so that they no longer talk about
658 returning 'pointers' to something.
660 2004-03-20 Han-Wen Nienhuys <hanwen@xs4all.nl>
662 * gc.c: remove set_debug_cell_accesses! when
663 SCM_DEBUG_CELL_ACCESSES is not defined. Scheme source code should
664 use (if (defined? 'set-debug-cell-accesses!) .. ) to switch on
665 debugging conditionally.
667 2004-03-21 Kevin Ryde <user42@zip.com.au>
669 * stime.c (scm_gmtime): Use gmtime_r when available, for thread safety.
671 2004-03-20 Kevin Ryde <user42@zip.com.au>
673 * posix.c (scm_gethostname): Preserve errno across free() call.
675 2004-03-18 Han-Wen Nienhuys <hanwen@xs4all.nl>
677 * gc-card.c (sweep_card): use SCM_GC_SET_CELL_WORD for setting
680 2004-03-14 Kevin Ryde <user42@zip.com.au>
682 * stime.c: Define _GNU_SOURCE for strptime prototype from glibc.
683 (strptime): Use HAVE_DECL_STRPTIME for when to give own prototype.
685 2004-03-07 Kevin Ryde <user42@zip.com.au>
687 * stime.c (scm_gmtime): Return bd_time->tm_zone when available, rather
689 (filltime): Make zname parameter "const".
691 2004-03-03 Mikael Djurfeldt <mdj@chunk.mit.edu>
693 * threads.c, threads.h (scm_c_scm2thread): New function.
695 2004-02-29 Kevin Ryde <user42@zip.com.au>
697 * numbers.c (guile_ieee_init): Use C99 INFINITY and NAN when
698 available. Test HAVE_DINFINITY and HAVE_DQNAN for those globals, in
699 particular don't assume "defined (__alpha__) && ! defined (linux)"
700 means OSF. Remove "SCO" code, which was not really SCO specific and
701 which John W. Eaton advises should be long past being needed.
703 * posix.c (scm_execl, scm_execlp, scm_execle): Avoid memory leak under
706 2004-02-24 Kevin Ryde <user42@zip.com.au>
708 * posix.c (scm_cuserid): Use a private result buffer, for thread safe.
710 2004-02-22 Kevin Ryde <user42@zip.com.au>
712 * numbers.c (scm_max, scm_min): For one arg, dispatch to generic for
713 complex, same as for two args. (Handle only inum, big, real, frac).
715 2004-02-21 Kevin Ryde <user42@zip.com.au>
717 * posix.c (scm_crypt): Use new HAVE_CRYPT.
718 (<crypt.h>): Remove HAVE_LIBCRYPT condition.
719 Reported by Andreas Voegele.
721 2004-02-20 Neil Jerram <neil@ossau.uklinux.net>
723 * list.c (scm_list_n): Add #if SCM_DEBUG_CELL_ACCESSES_P around
726 * read.c (scm_lreadparen): Removed.
727 (scm_lreadparen1): Renamed scm_i_lreadparen.
729 2004-02-20 Han-Wen Nienhuys <hanwen@xs4all.nl>
731 * list.c (scm_list_n): validate non-immediate arguments;
732 this will catch forgotten a SCM_UNDEFINED.
734 2004-02-18 Marius Vollmer <mvo@zagadka.de>
736 * gc.h (scm_gc_cells_collected): Removed duplicated declaration.
737 Thanks to Bill Schottstaedt!
739 * socket.h (scm_gethost): Removed prototype it is already in
740 "net_db.h". Thanks to Bill Schottstaedt!
742 2004-02-18 Kevin Ryde <user42@zip.com.au>
744 * num2integral.i.c (INTEGRAL2BIG): WORDS_BIGENDIAN not right for word
745 order parameter to mpz_import, in fact with just one word there's no
746 order to worry about at all.
748 * numbers.c (scm_num_eq_p): For real==frac, complex==frac, frac==real
749 and frac==complex, make an exact comparison rather than converting
750 with fraction2double.
752 * posix.c, putenv.c, stime.c (environ): Use _NSGetEnviron in Darwin
753 shared library, since environ is not directly available there.
755 * script.c (scm_shell_usage): Print to stdout for --help, per GNU
758 * stime.c (scm_localtime, scm_gmtime, scm_mktime): Provide a default
759 errno EINVAL in case localtime and gmtime don't set it.
760 (scm_mktime, scm_strptime): Forcibly use errno EINVAL for our
761 SCM_SYSERROR, since mktime and strptime generally don't set errno.
763 2004-02-16 Kevin Ryde <kevin@swox.se>
765 * gc-malloc.c (scm_done_malloc, scm_done_free): Allow negative sizes,
766 which were permitted in the past for these.
768 * num2float.i.c (NUM2FLOAT): Expand isfinite to !xisinf, as per
769 previous change to numbers.c.
771 * script.c (scm_shell_usage): Print bug-guile email address, as per
772 GNU standard. Reported by Han-Wen Nienhuys.
774 2004-02-13 Mikael Djurfeldt <djurfeldt@nada.kth.se>
776 * unif.c (scm_make_uve): Removed local variable and simplified
777 code in order to avoid compiler used uninitialized warnings.
779 * hashtab.c, hashtab.h (scm_hash_map_to_list): Renamed from
781 (scm_hash_fold): Use scm_call_3 directly in the call to
782 scm_internal_hash_fold instead of going via fold_proc (which is
784 (scm_hash_for_each): Use a trampoline +
785 scm_internal_hash_for_each_handle.
786 (scm_internal_hash_for_each_handle, scm_hash_for_each_handle): New
789 2004-02-12 Kevin Ryde <user42@zip.com.au>

792 (scm_set_port_line_x): In docstring, note first line is 0.
793 (scm_port_column): In docstring, there's no default to current input
794 port, and remove shared port-line @defun.
795 (scm_set_port_column_x): In docstring, there's no default to current
796 input port, note first column is 0, remove shared set-port-line!
799 * ramap.c (scm_array_fill_x): For fvect and dvect, use scm_num2dbl to
800 convert args the same way that array-set! does.
802 * unif.c (scm_make_uve, scm_array_p): Allow fraction 1/3 as prototype
804 (scm_array_p): Add missing "break"s in switch, fix llvect test look
805 for "l" not "s", fix dvect to be false for singp(prot) since such a
807 (scm_array_prototype): Return 1/3 for dvect, rather than 0.33..33.
808 (exactly_one_third): New variable.

816 2004-02-08 Neil Jerram <neil@ossau.uklinux.net>
818 * read.c (scm_read_opts): New opts `elisp-vectors' and
821 (scm_lreadr): Use scm_lreadparen1 instead of scm_lreadparen. Make
822 handling of elisp vector syntax dependent on SCM_ENABLE_ELISP and
823 `elisp-vectors' option instead of SCM_ELISP_READ_EXTENSIONS.
824 Allow "\(" and "\)" in strings when SCM_ENABLE_ELISP defined and
825 `escaped-parens' option set.
826 (scm_read_token): If elisp vector syntax active, disallow [ and ]
828 (scm_lreadparen): Rewrite as interface to scm_lreadparen1.
829 (scm_lreadparen1): New.
831 * read.h: Remove conditionally compiled last arg to
833 (SCM_ELISP_VECTORS_P, SCM_ESCAPED_PARENS_P): New.
835 2004-01-23 Han-Wen Nienhuys <hanwen@xs4all.nl>
837 * eval.c (m_expand_body): remove stray variable new_body.
839 2004-01-22 Marius Vollmer <mvo@zagadka.de>
841 * eval.c (m_expand_body): Rewrite the expression in place (by
842 overwriting FORMS) also when a letrec is constructed, not only
843 when no definitions are found. Do not return rewritten expression
844 to emphasize the in-place rewriting. Changed all users.
846 2004-01-19 Han-Wen Nienhuys <hanwen@xs4all.nl>
848 * gc.c: add protected_object_count, a number that is dumped from
851 2004-01-11 Marius Vollmer <mvo@zagadka.de>
853 * dynwind.h, dynwind.c (scm_frame_unwind,
854 scm_frame_unwind_handler): Renamed and changed all uses.
855 (scm_frame_rewind, scm_frame_rewind_handler): Likewise.
857 2004-01-11 Kevin Ryde <user42@zip.com.au>
859 * unif.c (scm_bit_count, scm_bit_position, s_scm_bit_set_star_x,
860 s_scm_bit_count_star, s_scm_bit_invert_x): Clarify docstrings, as per
861 changes made to scheme-compound.texi.
863 2004-01-10 Marius Vollmer <mvo@zagadka.de>
865 * print.c (scm_print_symbol_name): Handle #{`foo}#, #{,foo}#,
866 #{.}#, and all numeric strings specially. Thanks to Paul Jarc!
868 * guile-snarf.in: Use mkdir to create a unique temporary directory
869 that we can safely use. Thanks to Stefan Nordhausen!
871 2004-01-07 Marius Vollmer <marius.vollmer@uni-dortmund.de>
873 * dynwind.h, dynwind.c (scm_i_dowinds): Removed 'explicit'
874 argument since it is always zero now. Changed all callers.
875 Removed code for handling fluids.
877 * fluids.c (scm_c_with_fluids): Use frames instead of adding to
878 the wind chain explicitely. Use scm_c_with_fluid for the common
879 case of only one fluid.
880 (scm_with_fluid): New.
881 (scm_c_with_fluid): Use frames instead of scm_c_with_fluids.
883 * fluids.h, fluids.c (scm_frame_fluid): New.
884 (scm_with_fluid): New.
885 (scm_i_swap_fluids, scm_i_swap_fluids_reverse): Removed.
887 * dynwind.c (scm_frame_end): Do not use scm_i_dowinds. Instead,
888 do the unwinding directly. It is simple enough.
890 * dynwind.h, dynwind.c: Did the following renamings:
891 scm_begin_frame -> scm_frame_begin,
892 scm_end_frame -> scm_frame_end,
893 scm_on_unwind -> scm_frame_unwind,
894 scm_on_rewind -> scm_frame_rewind,
895 scm_on_unwind_with_scm -> scm_frame_unwind_with_scm,
896 scm_on_rewind_with_scm -> scm_frame_rewind_with_scm.
899 * aync.h, async.c: Did the follwing renamings:
900 scm_with_blocked_asyncs -> scm_frame_block_asyncs,
901 scm_with_unblocked_asyncs -> scm_frame_unblock_asyncs.
904 * ports.h, ports.c: Did the follwing renamings:
905 scm_with_current_input_port -> scm_frame_current_input_port,
906 scm_with_current_output_port -> scm_frame_current_output_port,
907 scm_with_current_error_port -> scm_frame_current_error_port.
910 2004-01-07 Kevin Ryde <user42@zip.com.au>
912 * numbers.c (s_bignum): Remove, not used since gmp bignums.
913 Reported by Richard Todd.
915 * threads-plugin.h (SCM_MUTEX_MAXSIZE): Increase to 12*sizeof(long),
916 for the benefit of powerpc-apple-darwin5.5. Reported by Richard Todd.
918 * unif.c (scm_aind): Test SCM_CONSP rather than !SCM_NULLP while
919 traversing the args list, fixes segv if an improper list is given.
920 Reported by Rouben Rostamian.
922 2004-01-06 Marius Vollmer <marius.vollmer@uni-dortmund.de>
924 * ports.c (swap_ports, scm_with_current_foo_port): Do not allocate
925 swap_data on stack, use a 'malloc obj'.
927 * fluids.h, fluids.c (scm_make_initial_fluids, scm_copy_fluids,
928 scm_swap_fluids, scm_swap_fluids_reverse): Renamed to
929 scm_i_... since they are internal. Changed all uses.
931 * dynwind.c (frame_print): Removed, use the default printer.
932 (WINDER_F_MARK, WINDER_MARK_P, winder_mark): New.
933 (scm_on_unwind_with_scm, scm_on_rewind_with_scm): New. Use above
934 to protect SCM values.
936 * dynwind.h (SCM_F_WIND_EXPLICITELY,
937 SCM_F_WIND_EXPLICITLY): It's "explicitly" not "explicitely", damn.
939 (scm_on_unwind_with_scm, scm_on_rewind_with_scm): New.
941 2004-01-05 Marius Vollmer <mvo@zagadka.de>
943 * ports.h, ports.c (scm_with_current_input_port,
944 scm_with_current_output_port, scm_with_current_error_port): New.
946 * async.h, async.c (scm_with_blocked_asyncs,
947 scm_with_unblocked_asyncs): New.
949 2004-01-03 Marius Vollmer <mvo@zagadka.de>
951 * dynwind.h, scm_dynwind.c (scm_t_frame_flags, scm_t_wind_flags,
952 scm_begin_frame, scm_end_frame, scm_on_unwind, scm_on_rewind):
954 (scm_dowinds, scm_i_dowinds): scm_dowinds has been renamed to
955 scm_i_dowinds and extended to handle frames and to invoke a 'turn'
956 function when the outermost wind point has been reached. The
957 latter is used to copy a continuation stack at the right time.
958 scm_dowinds remains available.
959 (SCM_GUARDSP, SCM_BEFORE_GUARD, SCM_AFTER_GUARD, SCM_GUARD_DATA,
960 tc16_guard, guards_print): Removed.
961 (scm_internal_dynamic_wind): Reimplemented using frames.
963 * continuations.c (copy_stack): New, do only the stack copying
964 part of copy_stack_and_call.
965 (copy_stack_and_call): Copy the stack after unwinding and before
967 (scm_dynthrow): Do not call scm_dowinds, this is now done by
970 2004-01-04 Kevin Ryde <user42@zip.com.au>
972 * numbers.c (scm_less_p): Don't convert frac to float for compares,
973 can give bad results due to rounding.
975 * stime.c (scm_current_time, scm_gettimeofday): Add a comment about
976 setzone/restorezone protection for DOS.
978 2003-12-26 Marius Vollmer <mvo@zagadka.de>
980 * gen-scmconfig.h.in, gen-scmconfig.c: Arrange for scm_t_intmax
981 and scm_t_uintmax to be defined in scmconfig.h
983 2003-12-03 Kevin Ryde <user42@zip.com.au>
985 * numbers.c (scm_less_p): Remove spurious xisnan from frac+big case.
987 * numbers.c (scm_make_ratio): Check for numerator equal to
988 SCM_MOST_NEGATIVE_FIXNUM and bignum denominator the negative of that,
991 * numbers.c (scm_real_part): Return fraction unchanged rather than
992 converting to flonum.
994 2003-11-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
996 * modules.c (module_variable): Fixed (and thus simplified) the
997 definition of SCM_BOUND_THING_P to reflect the fact that since
998 after the 1.4 series of guile, obarrays only hold variable
1001 2003-11-30 Marius Vollmer <mvo@zagadka.de>
1003 * numbers.c (scm_logand): It's "#b...", not "#\b...".
1007 * read.c (scm_lreadr): Signal an error for invalid escape
1008 sequences in strings. Code cleanups too.
1010 * print.c (scm_iprin1): use \xNN hexadecimal sequences when
1011 writing control characters in strings.
1013 2003-11-21 Marius Vollmer <mvo@zagadka.de>
1015 * ports.c (scm_drain_input): Bug fix: only access the port after
1016 checking that it indeed is one.
1018 2003-11-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
1020 * eval.c (s_bad_define): New static identifier.
1022 (m_body): Fixed comment.
1024 (scm_m_define): Don't generate memoized code for definitions that
1025 are not on the top level. As a consequence, no memoized code at
1026 all is generated for definitions any more: Top level definitions
1027 are executed immediately during memoization and internal
1028 definitions are handled separately in m_expand_body.
1030 (scm_unmemocopy, unmemocopy): Removed code for unmemoizing
1031 definitions. Consequently, there is no unmemoizing code any more
1032 that might modify the environment. Thus, the old scm_unmemocopy
1033 is removed and the old unmemocopy is renamed to scm_unmemocopy.
1035 (SCM_CEVAL): The SCM_IM_DEFINE keyword can no longer occur in
1036 memoized code. Call EVALCAR for continuations. Prefer !SCM_NULLP
1037 over SCM_NIMP in places, where the argument is known to be part of
1040 2003-11-21 Kevin Ryde <user42@zip.com.au>
1042 * numbers.c (scm_abs): Allocate a new real only for negatives, as done
1045 * numbers.c (scm_bit_extract): Use mpz functions, rearrange inum case
1046 to share some shifting.
1048 * numbers.c (scm_integer_expt): Don't mpz_init after scm_i_clonebig or
1049 scm_i_mkbig, since they do so already. Don't mpz_clear a bignum SCM,
1052 2003-11-19 Marius Vollmer <mvo@zagadka.de>
1054 * numbers.c (scm_make_ratio): Rewritten to have a simpler
1055 structure. Previously, not all cases with a negative denominator
1058 * numbers.c (mem2decimal_from_point): use scm_divide instead of

1125 gen-scmconfig.c so that we don't need to add SCM_SIZEOF___INT64
1126 and SCM_SIZEOF_UNSIGNED___INT64 to the public namespace.

1510 into subtypes of scm_tc7_number.
1512 * tags.h (scm_tc7_number): New.
1514 * eq.c (scm_equal_p), eval.c (SCM_CEVAL), evalext.c

1542 This set of patches eliminates the dependency between the
1543 implementation of evaluator specific memoization codes and special
1544 constants like #f, '() etc. ('flags'), which are not evaluator
1545 specific. The goal is to remove definitions of evaluator
1546 memoization codes completely from the public interface. This will
1547 make it possible to experiment more freely with optimizations of
1548 guile's internal representation of memoized code.
1550 * objects.c (scm_class_of): Eliminate dependency on SCM_ISYMNUM.
1552 * print.c (iflagnames): New array, holding the printed names of

1567 SCM_IM_SLOT_SET_X, SCM_IM_DELAY, SCM_IM_FUTURE,
1568 SCM_IM_CALL_WITH_VALUES, SCM_IM_NIL_COND, SCM_IM_BIND): Changed
1571 (SCM_IFLAGP): SCM_IFLAGP now only tests for flags.
1573 (SCM_IFLAGP, SCM_MAKIFLAG, SCM_IFLAGNUM): Generalized to use the

1576 2003-09-15 Marius Vollmer <mvo@zagadka.de>
1578 * posix.c (scm_setgroups): Check that the gid list is not too
1579 long. Thanks to Paul Jarc!
1581 2003-09-14 Dirk Herrmann <D.Herrmann@tu-bs.de>
1583 * tags.h: Reduced the number of short instructions from 14 to 13.
1584 The typecode of the former 14th short instruction is now used to
1585 represent long instructions. Changed some comments to reflect
1588 (SCM_MAKISYM): ISYMs get a new tc7 code, namely the one that was
1589 previously used by SCM_IM_DEFINE.
1591 (SCM_IM_DEFINE): Turned into a long instruction.
1593 * eval.c (unmemocopy, SCM_CEVAL): Treat SCM_IM_DEFINE as a long
1596 * eval.c (SCM_CEVAL): Since characters and iflags have now a tc7
1597 code that is separate from all instructions, one level of dispatch
1598 for long instructions can be eliminated.
1600 * print.c (scm_isymnames): Removed some commented code.
1602 2003-09-12 Marius Vollmer <mvo@zagadka.de>
1604 * __scm.h (SCM_FENCE): Use __memory_barrier with the Intel
1607 * hashtab.h (scm_tc16_hashtable): Added "extern" declaration.
1609 * modules.c (scm_module_reverse_lookup): Check that the obarray
1610 really is a hashtable and do nothing if not.
1612 * inline.h: Use "extern inline" only with GCC. Use "static
1615 2003-09-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
1617 * numbers.h (SCM_INEXACTP, SCM_REALP, SCM_COMPLEXP): Removed uses
1618 of SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP.
1620 * numbers.h, deprecated.h (SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP,
1621 SCM_SLOPPY_COMPLEXP): Deprecated and moved from numbers.h to
1624 2003-09-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
1626 * eq.c (scm_eqv_p, scm_equal_p): Removed uses of
1627 SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP.
1629 * eq.c (scm_eqv_p, scm_equal_p): Reordered comparisons from
1630 0.0==some_expression to some_expression==0.0. The latter is
1631 better readable. The former is preferred by some people, since it
1632 leads to a compiler error when confusing == with =. However, when
1633 using gcc, a warning will be issued if in an if-statement an
1634 assigment appears. Since many Guile developers are using gcc,
1635 such errors will not remain unnoticed anyway. We can therefore
1636 focus on better readability.
1638 2003-09-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
1640 * tags.h: Added description of Guile's type system. Removed some
1641 old and misleading comments.

1645 * unit.c (scm_cvref): Eliminate unnecessary uses of SCM_NIMP,
1646 SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP.
1648 2003-09-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
1650 * numbers.h (SCM_MAKINUM): Define in terms of scm_tc2_int.
1652 (SCM_INEXACTP, SCM_REALP, SCM_COMPLEXP): Define in terms of the
1653 respective SLOPPY macro.
1655 2003-09-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
1657 * eq.c (scm_equal_p): Use SCM_TYP7 to check if an object is of
1658 type string, not SCM_TYP7S.
1660 2003-09-03 Kevin Ryde <user42@zip.com.au>
1662 * numbers.c (scm_lognot): Correction to docstring, ones-complement not
1665 * stime.c (scm_strptime): Add comment about glibc strptime %s and
1666 current timezone requiring SCM_DEFER_INTS.

1670 * script.c (scm_compile_shell_switches): Make -s switch optional
1671 if file to be loaded does not begin with a `-'. (Thanks to Aaron
1672 VanDevender for the patch!)
1674 2003-08-30 Kevin Ryde <user42@zip.com.au>
1676 * numbers.c (scm_lognot): Rewrite using ~ and mpz_com, for directness
1677 and to have non-integer types rejected as per other logical funcs.
1679 2003-08-28 Kevin Ryde <user42@zip.com.au>
1681 * gc.h (scm_remember_upto_here_1): Revise comments on the asm form.
1683 2003-08-23 Kevin Ryde <user42@zip.com.au>
1685 * simpos.c (scm_system): Remove SCM_DEFER_INTS, system() should be
1686 thread safe, and could take a long time too.
1688 2003-08-22 Kevin Ryde <user42@zip.com.au>
1690 * numbers.c (scm_difference): Correction to bignum - negative inum.
1692 2003-08-14 Kevin Ryde <user42@zip.com.au>
1694 * gc.h (scm_remember_upto_here_1, scm_remember_upto_here_2)
1695 [__GNUC__]: Use volatile asm macros rather than a function call.
1696 * gc.c (scm_remember_upto_here_1, scm_remember_upto_here_2): Undefine
1697 macros while defining functions.
1699 * simpos.c (getenv): Use <stdlib.h> for prototype.
1700 (scm_system): In docstring, refer to status:exit-val rather than
1703 2003-08-09 Kevin Ryde <user42@zip.com.au>
1705 * srcprop.c (scm_source_properties): Return plist from hash if it's a
1706 list set by source-properties! rather than an SRCPROPS object,
1708 2003-07-29 Kevin Ryde <user42@zip.com.au>
1710 * properties.c (scm_primitive_property_ref): In docstring, note
1711 parameters to not-found-proc, use hyphens rather than underscores for
1712 that parameter name.
1713 (scm_primitive_property_set_x): In docstring, VAL is the value
1716 2003-07-27 Marius Vollmer <mvo@zagadka.de>
1718 * print.c (scm_print_symbol_name): handle more weird characters by
1719 escaping the symbol name properly. Thanks to Paul Jarc!
1721 * posix.h (scm_setgroups): New prototype.
1722 * posix.c (scm_setgroups): New. Thanks to Paul Jarc!
1723 (scm_getgroups): Handle groups ids that don't fit into a fixnum.
1724 Don't use SCM_WRITABLE_VELTS.
1726 * gc.h (SCM_GC_SET_CELL_BVEC): New.
1727 * gc-card.c (scm_i_init_card_freelist): Use it. Thanks to
1730 * __scm.h (SCM_C_INLINE_KEYWORD): New.
1731 * numbers.c: Use it in place of SCM_C_INLINE so that the code
1732 compiles when SCM_C_INLINE is undefined.
1734 2003-07-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
1736 * __scm.h: Reformulated the architecture and compiler properties
1737 in terms of properties of scm_t_bits and SCM variables rather than
1738 in terms of c standard types. This is since it is not known which
1739 of the standard types scm_t_bits and SCM variables will be defined
1742 2003-07-24 Kevin Ryde <user42@zip.com.au>
1744 * numbers.c (scm_angle): Use scm_flo0 for non-negative inum, bignum
1747 2003-07-18 Kevin Ryde <user42@zip.com.au>
1749 * numbers.c (scm_product): In complex * bignum, correction to
1750 REAL/IMAG fetch, x is the complex, not y.
1752 2003-07-13 Mikael Djurfeldt <djurfeldt@nada.kth.se>
1754 * numbers.c (scm_odd_p, scm_even_p): Bugfix: Treat result of
1755 scm_inf_p test as Scheme values.
1756 (scm_sum): Bugfix: Normalize bignum created from a negative bignum
1757 and a positive inum.
1758 Use GNU indentation style.
1760 2003-07-12 Dirk Herrmann <D.Herrmann@tu-bs.de>
1762 * values.c (scm_values): Build lists of length 1 by using
1763 scm_list_1 instead of using scm_cons.
1765 2003-07-10 Kevin Ryde <user42@zip.com.au>
1767 * deprecation.c (scm_c_issue_deprecation_warning_fmt): Add va_end.
1768 * list.c (scm_list_n): Ditto.
1770 * gc-malloc.c (scm_gc_realloc): Define "ptr" at start of function.
1772 2003-07-08 Matthias Koeppe <mkoeppe@merkur.math.uni-magdeburg.de>
1774 * tags.h (scm_t_bits, scm_t_signed_bits, etc): Avoid solaris empty
1775 defines of INTPTR_MAX and UINTPTR_MAX, combine conditionals for
1776 scm_t_bits and scm_t_signed_bits to avoid any chance of one and not
1777 the other using intptr_t.
1779 2003-07-08 Kevin Ryde <user42@zip.com.au>
1781 * numbers.c (scm_make_polar): Use sincos, when available.
1782 (scm_magnitude): Use hypot.
1784 * ports.c (scm_char_ready_p, scm_peek_char): In docstrings, don't use
1785 @footnote since it doesn't go through to guile-procedures.txt.
1787 * threads.c (scm_call_with_new_thread): In docstring, use "( )"
1788 outside @var to quieten makeinfo, and use @code.
1790 2003-07-06 Han-Wen Nienhuys <hanwen@cs.uu.nl>
1792 * gc-malloc.c (decrease_mtrigger): new function
1793 (increase_mtrigger): new function, separate debug registering and
1794 mtrigger administration.
1795 (scm_gc_realloc): bugfix: do mtrigger administration before the
1796 actual realloc, for the realloc might invalidate a GC-d segment of
1797 memory. Thanks to Sam Hocevar for pointing this out.
1798 (scm_gc_realloc): use scm_malloc_reregister instead of
1799 unregistering and registering in sequence.
1801 2003-07-03 Han-Wen Nienhuys <hanwen@cs.uu.nl>
1803 * __scm.h (SCM_ASSERT): change "else" expansion to "do { } while (0)"
1805 2003-07-02 Han-Wen Nienhuys <hanwen@cs.uu.nl>
1807 * __scm.h (SCM_ASRTGO): add "else" to macro expansions with if
1810 2003-06-29 Marius Vollmer <mvo@zagadka.de>
1812 * deprecated.h (SCM_OPDIRP, scm_fport, scm_option, scm_srcprops,
1813 scm_srcprops_chunk, scm_info_frame, scm_stack, scm_array,
1814 scm_array_dim, SCM_ARRAY_CONTIGUOUS, SCM_FUNC_NAME, SCM_WTA,
1815 RETURN_SCM_WTA, SCM_VALIDATE_NUMBER_COPY,
1816 SCM_VALIDATE_NUMBER_DEF_COPY, SCM_VALIDATE_OPDIR): Re-added from
1817 the release_1_6 branch.
1819 2003-06-25 Stefan Jahn <stefan@lkcc.org>
1821 * continuations.c: Redeclaration of getcontext() via the
1822 __asm__ ("getcontext") directive.

1827 2003-06-21 Kevin Ryde <user42@zip.com.au>
1829 * numbers.c (_GNU_SOURCE): #define, to get C99 things.
1830 (scm_asinh, scm_acosh, scm_atanh, scm_truncate, $asinh, $acosh,
1831 $atanh, truncate): Use C library asinh, acosh, atanh and trunc, when
1833 (scm_inexact_to_exact): Expand isfinite to its definition !xisinf.
1834 (isfinite): Remove, conflicts with C99 isfinite().

1843 the release_1_6 branch.
1845 2003-06-14 Stefan Jahn <stefan@lkcc.org>
1847 * threads.h: Redefined scm_getspecific() and scm_setspecific()
1848 to be functions instead of macros.
1850 * threads.c: Conditionalized inclusion of <sys/time.h> and
1852 (scm_getspecific, scm_setspecific): Made these two function
1853 real part of the API.
1855 * posix.c (s_scm_putenv): Added some code to make a
1856 (putenv "FOO="), i.e. setting an empty string, work also on
1857 Win32 systems. Thanks to Kevin Ryde for the proposal.
1859 2003-06-12 Kevin Ryde <user42@zip.com.au>
1861 * posix.c (scm_putenv): Free temporary ptr in mingw unset. Add
1862 freebsd to comment about need to use unsetenv.

1866 * ports.c (scm_peek_char): Safe the column of the port around the
1867 getc/ungetc calls. Thanks to Dr. Peter Ivanyi!
1869 2003-06-07 Kevin Ryde <user42@zip.com.au>
1871 * tags.h: Use inttypes.h and stdint.h when available, for INTPTR_MAX

1874 2003-06-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
1876 * tags.h (scm_tc2_int): Added.
1878 * tags.h (scm_tc3_int_1, scm_tc3_int_2): Expressed in terms of
1881 * tags.h (scm_tcs_cons_imcar, scm_tcs_cons_nimcar, scm_tcs_struct,
1882 scm_tcs_closures): Hard coded values replaced by symbolic ones.
1884 2003-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1886 * eval.c: Partially undid my patch from 2003-05-31. This patch
1887 caused the segfault referenced in the previous changelog entry.
1889 2003-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1891 * tags.h: Fixed comment about the immediate type code layout.
1893 * eval.c: Fixed handling of non-special instructions. Without
1894 this patch, guile will segfault on (#\0) and similar instructions.
1896 2003-06-05 Kevin Ryde <user42@zip.com.au>
1898 * numbers.c (scm_max, scm_min): For inum, bignum and real, if other
1899 operand is NaN, then return NaN. Also avoid passing NaN to mpz_cmp_d.
1901 * read.c (scm_input_error): Pass arg list parameter to scm_error_scm,
1902 rather than SCM_EOL. Needed by "Unknown # object" case in scm_lreadr.
1904 2003-06-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
1906 * __scm.h, gc-card.c (SCM_DEBUG_DEBUGGER_SUPPORT,
1907 SCM_DEBUG_DEBUGGING_SUPPORT): Renamed macro
1908 SCM_DEBUG_DEBUGGER_SUPPORT to SCM_DEBUG_DEBUGGING_SUPPORT and
1909 generalized it to apply not only to C level functions but also to
1910 scheme level functions.
1912 * debug.c, debug.h, eval.c (make-iloc, scm_make_iloc, iloc?,
1913 scm_iloc_p, dbg-make-iloc, scm_dbg_make_iloc, dbg-iloc?,
1914 scm_dbg_iloc_p): Moved functions scm_make_iloc, scm_iloc_p to
1915 eval.c, made them available under SCM_DEBUG_DEBUGGING_SUPPORT == 1
1916 only and renamed them to scm_dbg_make_iloc, scm_dbg_iloc_p,
1919 * deprecated.h, eval.c, eval.h (SCM_ILOC00, SCM_IDINC,
1920 SCM_IDSTMSK): Deprecated. The macro definitions are moved from
1921 eval.h into eval.c and a copy is placed into deprecated.h.
1923 * eval.c, eval.h (SCM_MAKE_ILOC): Removed from eval.h and placed
1924 into eval.c. This definition was not part of the API in any
1925 officially released version of guile and thus does not need to go
1926 through a phase of deprecation.
1928 2003-06-02 Dirk Herrmann <D.Herrmann@tu-bs.de>
1930 * deprecated.c, deprecated.h, eval.c, eval.h (scm_s_expression,
1931 scm_s_test, scm_s_body, scm_s_bindings, scm_s_variable,
1932 scm_s_clauses, scm_s_formals): Deprecated. In eval.c the
1933 definitions are make static and renamed from scm_s_xxx to s_xxx.
1934 In deprecated.c the original definitions are copied.
1936 * deprecated.h, eval.c, eval (SCM_EVALIM2, SCM_EVALIM, SCM_XEVAL,
1937 SCM_XEVALCAR): Deprecated. The macro definitions are moved from
1938 eval.h into eval.c and a copy (slightly modified to work in user
1939 code) is placed into deprecated.h.
1941 * eval.c: Use the local static s_xxx definitions instead of the
1942 scm_s_xxx definitions throughout.
1944 2003-06-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
1946 This set of patches separates the representation of the cxr family
1947 of functions (car, cdr etc.) from the dsubr family of functions
1948 (i. e. functions that take a double precision floating point
1949 argument). Further, the algorithm for handling the cxr function

1956 (scm_i_procedure_arity), ramap.c (scm_array_map_x), tags.h
1957 (scm_tc7_dsubr, scm_tcs_subrs): Introduce scm_tc7_dsubr as new
1958 typecode for the dsubr family of functions.
1960 * ramap.c (ramap_cxr, ramap_dsubr): Renamed ramap_cxr to
1963 * eval.c (SCM_CEVAL, SCM_APPLY, call_cxr_1), pairs.c
1964 (scm_init_pairs): Make use of the (now usable) second cell element
1965 of a scm_tc7_cxr function to implement the cxr family of functions
1968 2003-05-31 Dirk Herrmann <D.Herrmann@tu-bs.de>
1970 * eval.c (SCM_CEVAL, SCM_APPLY, scm_trampoline_0,
1971 scm_trampoline_1, scm_trampoline_2): Postpone error cases to the
1972 end of an if-else-if-sequence of checks.
1974 2003-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
1976 * eval.c (SCM_CEVAL): Improved readability of call-with-values
1977 execution. Generalize apply_closure to apply_proc and use that
1978 for call-with-values.
1980 2003-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
1982 * eval.c (SCM_CEVAL): Avoid one level of indirection when applying

2003 * stime.c (s_scm_strftime): Add a type cast to avoid compiler
2006 * posix.c (s_scm_putenv): Disable use of unsetenv() for the
2009 * modules.c (s_scm_module_import_interface): Renamed local
2010 variable interface to _interface. Seems like 'interface'
2011 is a special compiler directive for the mingw32 compiler.
2013 * mkstemp.c: Provide prototype to avoid compiler warning.
2015 * load.c (s_scm_search_path): Fixed absolute and relative
2016 path detections for native Windows platforms.
2018 * gc.h, threads.h: Export some more symbols using SCM_API (necessary
2019 to build on mingw32).
2021 * gc-freelist.c ("s_scm_map_free_list",
2022 "s_scm_gc_set_debug_check_freelist_x"): Fixed use of FUNC_NAME.

2034 proper function object and the correct number of arguments are now
2035 performed in the application part of SCM_CEVAL.
2037 (scm_badformalsp): Removed.
2039 2003-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>

2089 yyget_text, yyset_lineno, yyset_in, yyset_out, yyget_debug,
2090 yyset_debug, yylex_destroy): Added prototypes (otherwise we'll get
2091 a compilation error if error-on-warning is enabled).
2093 2003-05-17 Marius Vollmer <mvo@zagadka.de>
2095 * c-tokenize.lex: Gobble up complete lines after a '#'. This
2096 removes preprocessor directives from the snarfage that might
2097 otherwise confuse us. These directives appear when compiling with
2100 2003-05-16 Han-Wen Nienhuys <hanwen@cs.uu.nl>
2102 * ChangeLog: add my surname
2104 * srcprop.c (scm_finish_srcprop): use
2105 scm_gc_register_collectable_memory()

2117 * numbers.c (xmpz_cmp_d): New macro, handling infs if gmp doesn't.
2118 (scm_num_eq_p, scm_less_p, scm_max, scm_min): Use it.
2120 2003-05-12 Mikael Djurfeldt <djurfeldt@nada.kth.se>
2122 * backtrace.c (scm_display_error_message): Introduced fancy
2123 printing with max level 7 and length 10. (Purpose: avoid printing
2124 gigantic objects in error messages.)
2126 * print.c, print.h (scm_i_port_with_print_state): New function.
2128 * print.c (scm_iprin1, scm_printer_apply,

2138 2003-05-10 Kevin Ryde <user42@zip.com.au>
2140 * numbers.c (scm_num_eq_p, scm_less_p): Don't pass NaN to mpz_cmp_d.
2142 * numbers.c (scm_integer_length): On negative bignums, adjust
2143 mpz_sizeinbase to account for it looking at absolute value where we
2144 want ones-complement.
2146 * numbers.c (scm_gcd): In bignum/inum, don't pass yy==0 to mpz_gcd_ui
2147 since we're only using the ulong return value, and x might not fit.
2149 2003-05-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
2151 * eval.c, eval.h, read.c, read.h (scm_sym_dot): Moved from eval to
2152 read. This will allow to make the definition in read.c static.
2154 2003-05-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
2156 * eval.c, eval.h, evalext.c, evalext.h (scm_m_undefine): Moved

2162 * numbers.c (scm_difference): In inum - bignum, handle negative inum.
2163 (scm_logcount): Use mpz_com, not mpz_neg.
2165 2003-05-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
2167 The purpose of this patch is to make guile's internal memoizers
2168 distinguishable from memoizing macros created on the scheme level
2169 or from user provided primitive memoizing macros. The reason is,
2170 that the internal memoizers are the only ones that are allowed to
2171 transform their scheme input into memoizer byte code, while all
2172 other memoizing macros may only transform scheme code into new
2175 To achieve this, a new macro type 'builtin-macro!' is introduced.
2176 Currently, 'builtin-macro!'s are handled as memoizing macros, but
2177 this will change when the memoizer and executor are separated.
2179 * macros.[ch] (scm_i_makbimacro): New.
2181 * macros.h (SCM_BUILTIN_MACRO_P): New.
2183 * macros.c (macro_print, scm_macro_type): Support builtin-macro!s.

2186 primitive builtin-macros now.
2188 * eval.c (scm_macroexp, SCM_CEVAL): Make sure the primitive
2189 builtin-macros are handled equally to memoizing macros.
2191 2003-05-04 Marius Vollmer <mvo@zagadka.de>
2193 * throw.c (scm_ithrow): Remove "asm volatile" hack. It used to
2194 work around a bug in GCC 2.95.2 but is now a bug in itself.
2196 2003-05-02 Marius Vollmer <mvo@zagadka.de>
2198 * deprecated.h (scm_rstate, scm_rng, SCM_SLOPPY_CONSP,
2199 SCM_SLOPPY_NCONSP, scm_tc7_ssymbol, scm_tc7_msymbol,
2200 scm_tcs_symbols): New.
2202 2003-04-30 Marius Vollmer <marius.vollmer@uni-dortmund.de>
2204 * deprecated.h, deprecated.c (scm_protect_object,

2221 macro was introduced in anticipation of GOOPS method compilation
2224 * goops.c: Removed binding of @dispatch.
2226 2003-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
2228 * eval.c, goops.c (@dispatch, @slot-ref, @slot-set!): Move the
2229 instructions that bind the macros on the scheme level back to
2230 goops.c in order to make sure again that the bindings go into the
2231 (oop goops) module and are not visible from the outside.
2233 2003-04-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
2235 * eval.c: Non functional change: Separated R5RS and non-R5RS
2236 macros into different sections of the file and ordered the
2237 memoizers alphabetically.
2239 2003-04-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
2241 * eval.c (scm_ilookup): Rewritten to improve readability.

2246 Partially reverted patch from 2003-04-23 in oder to find a better
2247 compromise between readability and debuggability.
2249 2003-04-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2251 * eval.c, eval.h, goops.c, goops.h (scm_m_atslot_ref,
2252 scm_m_atslot_set_x, scm_m_atdispatch): Move the declarations and
2253 definitions of the special goops memoizers from goops.[ch] to
2254 eval.[ch]. Hmm... it seems that scm_m_atdispatch is not used
2257 2003-04-24 Mikael Djurfeldt <mdj@kvast.blakulla.net>
2259 * ports.c, ports.h (scm_i_port_table_mutex): New mutex.

2276 2003-04-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
2278 This set of patches contains no functional changes, only debatable
2279 minor stylistic ones. Still, in order to prepare a patch between
2280 my local copy and the CVS version, I decided to submit the changes
2281 below. Then, the patch will hopefully only contain relevant
2284 * eval.c (iqq): Added const specifier.
2286 * eval.c (scm_trampoline_0, scm_trampoline_1, scm_trampoline_2):
2287 Use NULL instead of 0 to indicate that a pointer is returned.
2288 Removed some misleading 'fall through' comments.

2296 * eval.h (SCM_ENTER_FRAME_HDLR, SCM_APPLY_FRAME_HDLR,
2297 SCM_EXIT_FRAME_HDLR): Use SCM_PACK to convert data to a SCM value
2298 rather than casting to SCM.
2300 2003-04-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
2302 * sort.c, pairs.h: Removed unnecessary includes.
2304 2003-04-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
2306 * sort.c: Replaced hand-made trampline code by the new official
2307 mechanism from eval.c. This fixes a segfault in the new test file
2310 (quicksort, compare_function, scm_restricted_vector_sort_x,
2311 scm_sorted_p, scm_merge, scm_merge_list_x, scm_merge_x,
2312 scm_merge_list_step, scm_sort_x, scm_sort, scm_merge_vector_x,
2313 scm_merge_vector_step, scm_stable_sort_x, scm_stable_sort,
2314 scm_sort_list_x, scm_sort_list): Use trampoline mechanism from
2317 (subr2less, lsubrless, closureless, applyless, scm_cmp_function,
2318 cmp_fun_t): Removed.
2320 (compare_function): Added.
2322 * sort.c (quicksort, SWAP, stack_node): Replaced pointer
2323 arithmetics with index arithmetics. Changed quicksort to work on
2324 an array of SCM values instead of an array of characters. Avoid
2325 bytewise copying of SCM elements. Avoid allocating memory on the
2326 stack with alloca. Fixed some comments.
2328 2003-04-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2330 * eval.c (EXTEND_ENV): Eliminated.
2332 (unmemocopy, SCM_CEVAL, SCM_APPLY): Use SCM_EXTEND_ENV instead of

2337 * __scm.h (SCM_DEBUG_DEBUGGER_SUPPORT): New compile-time option.
2339 * gc.card.c (scm_gc_marked_p): Fixed compiler warning when
2340 compiling with SCM_DEBUG==1 by moving definition behind prototype.
2342 * gc.card.c (scm_dbg_t_list_cell, scm_dbg_t_double_cell,
2343 scm_dbg_gc_marked_p, scm_dbg_gc_get_card, scm_dbg_gc_get_bvec,
2344 scm_t_list_cell_struct, scm_t_list_cell, scm_t_double_cell,
2345 scm_gc_marked_p, scm_gc_get_card, scm_gc_get_bvec): Fixed
2346 functions such that they check if the object is a non-immediate.
2347 Further, renamed identifiers to use the scm_dbg_ prefix and made
2348 their inclusion into the lib dependent of the
2349 SCM_DEBUG_DEBUGGER_SUPPORT compile time option.
2351 2003-04-21 Dirk Herrmann <D.Herrmann@tu-bs.de>

2356 2003-04-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2358 * list.c (scm_ilength, scm_last_pair), unif.c (l2ra): Prefer
2359 !SCM_CONSP over SCM_NCONSP. Now, guile itself does not include
2360 any calls to SCM_NCONSP any more.
2362 * unif.c (l2ra): Eliminate redundant check.
2364 2003-04-21 Dirk Herrmann <D.Herrmann@tu-bs.de>

2367 scm_array_map_x), unif.c (l2ra): Prefer !SCM_NULLP over
2368 SCM_NNULLP. Now, guile itself does not include any calls to

2375 other expressions into an expression of their own.
2377 2003-04-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2379 * goops.c (TEST_CHANGE_CLASS, scm_sys_initialize_object): Don't
2380 compare SCM values with !=.

2384 * eval.c, eval.h, evalext.c, evalext.h (scm_sym_setter,
2385 scm_m_generalized_set_x, scm_init_evalext): Move the declaration
2386 and definition of the memoizer for the generalized set! macro from
2387 evalext.[ch] to eval.[ch]. Use the SCM_SYNTAX snarfer macro to
2388 define the macro object.
2390 * eval.c, eval.h (s_set_x, scm_s_set_x, scm_m_set_x,
2391 scm_m_generalized_set_x): Since now scm_s_set_x is only used in
2392 eval.c, it is made static and renamed to s_set_x.

2397 2003-04-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2399 * eval.c, root.h (scm_undefineds, SCM_NUM_PROTECTS, undefineds,
2400 scm_init_eval): Made scm_undefineds static in eval.c, renamed it
2401 to undefineds and registered the object as a permanent object.
2403 * eval.c, eval.h (scm_f_apply, scm_init_eval): Made scm_f_apply
2404 static in eval.c, renamed it to f_apply and registered the object
2405 as a permanent object.
2407 2003-04-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2409 * eval.c (SCM_BIT7, SCM_BIT8, unmemocopy, SCM_CEVAL): Renamed
2410 file-local macro SCM_BIT8 to SCM_BIT7, which is more appropriate.
2412 2003-04-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2414 * numbers.c (scm_logtest): Fixed argument bug in the call to
2415 mpz_and, which showed up when compiling with SCM_DEBUG defined.

2470 * tags.h: scm_t_intptr should have been intptr_t.
2472 2003-04-13 Rob Browning <rlb@defaultvalue.org>
2474 * __scm.h (SCM_FLUSH_REGISTER_WINDOWS): don't just rely on "sparc"
2476 #if defined (sparc) || defined (__sparc__) || defined (__sparc)
2477 as gc_os_dep.c suggests is appropriate.
2479 * goops.c (prep_hashsets): make static to match prototype.
2480 (scm_sym_args): SCM_SYMBOL -> SCM_GLOBAL_SYMBOL. Thanks to Albert
2483 * c-tokenize.lex: remove trailing comma from enum. Thanks to

2516 * init.c: #include gmp.h.
2518 * numbers.h: remove the gmp.h #include (not needed now).
2520 * posix.h: change occurences of "id" to something else so we don't
2521 cause trouble when included via objective-c (can't hurt, might
2522 help). Still have usage in debug.h, though.
2524 2003-04-06 Mikael Djurfeldt <djurfeldt@nada.kth.se>
2526 * random.c (scm_c_random_bignum): Don't generate a random number
2527 equal to m (the second argument of scm_c_random_bignum); only
2528 generate numbers in the range 0 <= r < m.
2529 (scm_c_default_rstate): Use SCM_VARIABLE_REF to access
2530 scm_var_random_state.
2532 * num2integral.i.c (INTEGRAL2BIG): Put negation of n inside then

3105 a prime which is greater than this value).
3107 * symbols.c (scm_symbols_prehistory): Changed from 1009 to 2139
3108 (current number of initial symbols).
3110 * properties.c (scm_init_properties): Don't specify size of
3111 scm_properties_whash.
3113 * objprop.c (scm_init_objprop): Don't specify size of
3116 * keywords.c (scm_init_keywords): Don't specify a hash table size.
3118 * hooks.c (scm_c_hook_add): Fixed bug in append mode.
3120 The following changes introduce the use of resizable hash tables
3121 throughout Guile. It also renames the old *-hash-table* functions
3122 to *-alist-vector* and places them, together with the rest of the
3123 weak vector support, in the module (ice-9 weak-vector). We should
3124 probably introduce a new, better, API for weak references, for
3125 example "weak pairs" a la MIT-Scheme. (In Chez scheme, they even
3126 look like and are used like ordinary pairs.)
3128 * environments.c (obarray_enter, obarray_retrieve, obarray_remove,
3129 leaf_environment_fold, obarray_remove_all): Use hashtable
3132 * gc.c (scm_init_storage): Moved hook initialization to
3133 scm_storage_prehistory.
3134 (scm_storage_prehistory): New function.
3135 (scm_igc): Added commentary about placement of
3136 scm_after_sweep_c_hook.
3138 * gc-mark.c (scm_mark_all): Use hashtable accessors.
3139 (scm_gc_mark_dependencies): Use SCM_WVECT_WEAK_KEY_P and
3140 SCM_WVECT_WEAK_VALUE_P.
3142 * hashtab.c, hashtab.h (scm_hash_for_each, scm_hash_map): New
3144 (scm_vector_to_hash_table, scm_c_make_resizing_hash_table):
3146 (scm_make_weak_key_hash_table, scm_make_weak_value_hash_table,
3147 scm_make_doubly_weak_hash_table): Moved here from weaks.c.
3149 * init.c (scm_init_guile_1): Removed call to scm_init_weaks; Added
3150 calls to scm_storage_prehistory and scm_hashtab_prehistory.
3152 * modules.c (module-reverse-lookup): Use hashtable accessors.
3154 * symbols.c, symbols.h (scm_i_hash_symbol): New function.
3156 * weaks.c, weaks.h (scm_make_weak_key_alist_vector,
3157 scm_make_weak_value_alist_vector,
3158 scm_make_doubly_weak_alist_vector): New functions.
3160 * weaks.c (scm_init_weaks_builtins): New function.
3162 * weaks.h (SCM_WVECTF_WEAK_KEY, SCM_WVECTF_WEAK_VALUE,
3163 SCM_WVECTF_NOSCAN, SCM_WVECT_WEAK_KEY_P, SCM_WVECT_WEAK_VALUE_P,
3164 SCM_WVECT_NOSCAN_P): New macros.
3166 * weaks.c (scm_scan_weak_vectors): Use SCM_WVECT_WEAK_KEY_P
3167 and SCM_WVECT_WEAK_VALUE_P.
3169 * weaks.c, weaks.h (scm_i_allocate_weak_vector): Renamed from
3170 allocate_weak_vector and exported.
3172 2003-02-13 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3174 * hashtab.c: Undid thread safety. (We decided that it's better to
3175 let the user explicitly protect the tables (or not) according what
3176 is suitable for the application.)
3178 2003-02-12 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3180 * hashtab.c (scm_hash_fn_remove_x, scm_internal_hash_fold): Made
3181 thread safe and handle resizing tables.
3182 (scm_ihashx, scm_sloppy_assx, scm_delx_x): Removed
3183 SCM_DEFER/ALLOW_INTS.
3185 2003-02-11 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3187 * hashtab.c (scm_vector_to_hash_table,
3188 scm_c_make_resizing_hash_table, scm_make_hash_table): New
3190 (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x): Made thread
3191 safe and handle resizing tables.
3193 * weaks.c (scm_make_weak_key_hash_table,
3194 scm_make_weak_value_hash_table, scm_make_doubly_weak_hash_table):
3195 Size argument made optional. Return resizable table if not
3198 2003-02-10 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3200 * eval.c (scm_trampoline_0, scm_trampoline_1, scm_trampoline_2):
3201 Fixed formals tests for closures. (Thanks to Kevin Ryde.)
3203 2003-02-05 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3205 * debug.c (scm_procedure_source): Handle all objects for which
3206 procedure? is #t. (Thanks to Bill Schottstaedt.)
3208 2003-01-23 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3210 * futures.c (mark_futures): Don't need to mark data of recycled
3212 (scan_futures, cleanup_undead): Be smarter about marking
3213 futures---avoid unnecessary passes through future lists.
3215 * futures.h, futures.c: New files; Introduced recycling of
3216 futures. For fine-grained threading this lifts performance to
3217 another level. We can now use parallelization in inner loops of
3218 Guile programs without impossible overhead.
3220 * threads.h, threads.c: Moved futures to their own file.
3222 * Makefile.am (libguile_la_SOURCES): Added futures.c.
3223 (DOT_X_FILES): Added futures.x.
3224 (DOT_DOC_FILES): Added futures.doc.

3227 * threads.c, threads.h (scm_i_create_thread): Renamed from
3228 create_thread and made global.
3230 * futures.c (scm_make_future): New procedure.
3232 * eval.c: #include "libguile/futures.h".
3234 * init.c: #include "futures.h"
3235 (scm_init_guile_1): Call scm_init_futures.
3237 * stime.c (SCM_TIME_UNITS_PER_SECOND): Renamed from CLKTCK.
3239 * stime.h (SCM_TIME_UNITS_PER_SECOND): Definition moved here.
3241 * eval.c, eval.h (scm_trampoline_0, scm_i_call_closure_0): New
3244 * eval.c (scm_trampoline_1): Fixed arguments test for closures.
3246 2003-01-22 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3248 * threads.c (create_thread): Don't unwind dynwind chain of parent
3249 thread before creation. Just start the new thread with an empty
3252 2003-01-20 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3254 * evalext.c, evalext.h (scm_self_evaluating_p): New function.
3256 2003-01-10 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3258 * threads.c (scm_timed_wait_condition_variable): Support timed
3259 waiting also for simple condition variables.
3261 * goops.c (TEST_CHANGE_CLASS): Use scm_change_object_class instead
3262 of calling the procedure change-object-class.
3264 2003-01-09 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3266 * ramap.c (scm_ramapc): Typo in error message.
3268 2003-01-08 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3270 * goops.c (scm_sys_prep_layout_x): Bugfix: Only create layout for
3271 slots with instance allocation.
3273 * goops.c, goops.h (scm_class_extended_generic_with_setter): New
3275 (scm_compute_applicable_methods): Use scm_generic_function_methods.
3277 * goops.c (scm_generic_function_methods): Support extended
3280 2002-12-29 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3282 * eval.c (unmemocopy): Bugfix: scm_sym_delay --> scm_sym_future.
3283 Thanks to Neil for pointing this out!
3285 2002-12-29 Neil Jerram <neil@ossau.uklinux.net>
3287 * lang.h: Remove declarations matching definitions removed from
3288 lang.c (just below).
3290 2002-12-28 Neil Jerram <neil@ossau.uklinux.net>
3292 * lang.c (scm_nil_cons, scm_nil_car, scm_nil_cdr, scm_null,
3293 scm_m_while, scm_nil_eq): Remove definitions that were superfluous
3294 and already commented out.
3296 * read.h (scm_lreadparen), read.c (scm_lreadr, scm_read_token,
3297 scm_lreadparen): Support reading vectors with Elisp syntax if
3298 SCM_ELISP_READ_EXTENSIONS is defined. (SCM_ELISP_READ_EXTENSIONS
3299 is not currently defined, and there isn't even a configure switch
3302 2002-12-26 Marius Vollmer <mvo@zagadka.ping.de>
3304 * Makefile.am (c-tokenize.o): Refer to source via $< so that vpath
3306 (EXTRA_DIST): Added version.h.in.
3308 2002-12-21 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3310 This change makes it possible for one thread to do lazy sweeping
3311 while other threads are running. Now only the mark phase need to
3312 have all threads asleep. We should look further into this issue.
3313 Presently, I've put the locking of scm_i_sweep_mutex at
3314 "conservative" places due to my current lack of knowledge about
3315 the garbage collector. Please feel free to restrict these regions
3316 further to allow for maximal parallelism!
3318 * gc.c, gc.h (scm_i_sweep_mutex): New mutex.
3320 * gc.c (scm_gc_for_newcell), gc-malloc.c (scm_realloc,
3321 scm_gc_register_collectable_memory): Substitute locking of
3322 scm_i_sweep_mutex for calls to scm_i_thread_put_to_sleep.
3323 (scm_igc): Lock sweep mutex here instead of in callers; Calls to
3324 scm_i_thread_put_to_sleep/scm_i_thread_wake_up used to demarkate
3325 the single-thread section (which now only contains the mark
3327 (scm_gc): Don't lock sweeo mutex here since scm_igc locks it;
3328 Removed SCM_DEFER/ALLOW_INTS. Simply call scm_igc directly.
3330 * threads.c (gc_section_mutex): Removed.
3332 2002-12-19 Mikael Djurfeldt <mdj@kvast.blakulla.net>
3334 * threads.c (create_thread): Clear parent field in root state in
3335 order not to unnecessarily remember dead threads.
3337 * eval.c (call_subr2o_1, call_lsubr2_2): New functions.
3338 (scm_trampoline_1, scm_trampoline_2): Use them.
3340 2002-12-18 Mikael Djurfeldt <mdj@kvast.blakulla.net>
3342 Partial introduction of real plugin interface.
3344 * Makefile.am (modinclude_HEADERS): Added threads-plugin.h.
3345 (EXTRA_DIST): Added threads-plugin.c.
3347 * threads-plugin.h, threads-plugin.c: New files.
3349 * threads.h: #include "libguile/threads-plugin.h".
3351 * threads.c: #include "libguile/threads-plugin.c".
3353 * pthread-threads.c: Temporarily remove debugging functions.
3355 * threads.c, threads.h (scm_yield): Added back.
3357 2002-12-18 Mikael Djurfeldt <mdj@kvast.blakulla.net>
3359 * threads.c (really_launch): Detach before unlocking
3360 thread_admin_mutex in order not to risk being joined.
3361 (scm_i_thread_put_to_sleep, scm_i_thread_wake_up): Keep
3362 thread_admin_mutex locked during GC.
3364 * pthread-threads.c, pthread-threads.h: Improvements to debugging
3367 2002-12-16 Mikael Djurfeldt <mdj@kvast.blakulla.net>
3369 * pthread-threads.c, pthread-threads.h (SCM_DEBUG_THREADS): Added
3370 support for debugging mutex operations.
3372 * threads.c (scm_thread): Removed filed joining_threads.
3373 (thread_print): Print thread number as well as address of thread
3375 (scm_join_thread): Bugfix.
3376 (scm_lock_mutex, scm_try_mutex, scm_unlock_mutex,
3377 scm_timed_wait_condition_variable, scm_signal_condition_variable,
3378 scm_broadcast_condition_variable): Use the low-level API.
3379 (scm_all_threads): Return copy of thread list (to prevent
3380 unintended destruction).
3381 (scm_threads_prehistory): Initialize heap_mutex of fake thread.
3383 * pthread-threads.c, pthread-threads.h, threads.c: Fixes to
3384 pthread "native" recursive mutex support.
3386 2002-12-15 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3388 * __scm.h (SCM_DEFER_INTS, SCM_ALLOW_INTS): New definitions.
3389 Simply lock a thread C API recursive mutex.
3390 (SCM_NONREC_CRITICAL_SECTION_START,
3391 SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START,
3392 SCM_REC_CRITICAL_SECTION_END): Removed.
3394 * eval.c: Replaced SOURCE_SECTION_START / SOURCE_SECTION_END with
3395 direct calls to scm_rec_mutex_lock / unlock around the three calls
3396 to scm_m_expand_body.
3398 * eval.c, eval.h (promise_free): New function.
3399 (scm_force): Rewritten; Now thread-safe; Removed
3400 SCM_DEFER/ALLOW_INTS.
3402 * pthread-threads.h: Added partially implemented plugin interface
3403 for recursive mutexes. These are, for now, only intended to be
3404 used internally within the Guile implementation.
3406 * pthread-threads.c: New file.
3408 * threads.c: Conditionally #include "pthread-threads.c".
3410 * eval.c, eval.h (scm_makprom, scm_force): Rewritten to be
3413 * snarf.h (SCM_MUTEX, SCM_GLOBAL_MUTEX, SCM_REC_MUTEX,
3414 SCM_GLOBAL_REC_MUTEX): New macros.
3416 * eval.c, threads.c, threads.h, snarf.h: Rewrote critical section
3417 macros---use mutexes instead.
3419 * tags.h (SCM_IM_FUTURE): New tag.
3421 * eval.c (scm_m_future): New primitive macro.
3422 (SCM_CEVAL): Support futures.
3423 (unmemocopy): Support unmemoization of futures.
3425 * print.c (scm_isymnames): Name of future isym.
3427 * version.c: Unmade some changes to my private copy that got
3428 committed by mistake.
3430 2002-12-11 Mikael Djurfeldt <mdj@kvast.blakulla.net>
3432 * gc-malloc.c, gc.h, init.c: Reverted gc-malloc change of
3435 * gc.c (scm_igc): Don't call scm_i_thread_invalidate_freelists.
3437 * gc.c (scm_gc_sweep): Call it here instead, which is a more
3440 * threads.c (create_thread): Remember root object until the handle
3441 of the new thread is on all_threads list.
3443 * root.c (scm_make_root): Moved copying of fluids until after
3444 creation of root handle so that the fluids are GC protected. Also
3445 removed the critical section.
3447 2002-12-10 Mikael Djurfeldt <mdj@kvast.blakulla.net>
3449 * gc-malloc.c, gc.h (scm_gc_malloc_prehistory): New function.
3451 * gc-malloc.c (malloc_mutex): New mutex.
3452 (scm_gc_malloc_prehistory): Initialize it.
3453 (scm_realloc): Serialize call to realloc
3454 (scm_calloc): Same for calloc.
3455 Thanks to Wolfgang Jaehrling!
3456 (Now we have to make sure all calls to malloc/realloc are made
3457 through scm_malloc.)
3459 * init.c (scm_init_guile_1): Call scm_gc_malloc_prehistory.
3461 * threads.c (really_launch): Release heap (to prevent deadlock).
3462 (create_thread): Release heap before locking thread admin mutex.
3464 2002-12-10 Mikael Djurfeldt <mdj@kvast.blakulla.net>
3466 * threads.c (scm_i_thread_invalidate_freelists): New
3469 * gc.c (scm_igc): Call scm_i_thread_invalidate_freelists.
3471 * modules.c (scm_export): Inserted a return statement.
3473 2002-12-10 Han-Wen Nienhuys <hanwen@cs.uu.nl>
3475 * modules.c (scm_export): new function
3477 * gc-card.c: add a note about malloc()/free() overhead.
3479 2002-12-10 Mikael Djurfeldt <mdj@kvast.blakulla.net>
3481 * Makefile.am (c-tokenize.$(OBJEXT)): Don't look for c-tokenize.c
3484 2002-12-10 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3486 These changes remove scm_ints_disabled (which hasn't has any
3487 effect in Guile for quite some time).
3489 * async.c, error.h (scm_ints_disabled): Removed.
3491 * gc.c (scm_gc_for_newcell), init.c (scm_init_guile_1),
3492 root.c (scm_internal_cwdr), gdbint.c (SCM_BEGIN_FOREIGN_BLOCK,
3493 SCM_END_FOREIGN_BLOCK): Don't touch scm_ints_disabled.
3494 (old_ints): Removed.
3496 * __scm.h (SCM_DEFER_INTS, SCM_ALLOW_INTS): Define as a recursive
3498 (SCM_REDEFER_INTS, SCM_ALLOW_INTS): Define as SCM_DEFER_INTS and
3501 2002-12-09 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3503 * threads.c (scm_mutex_lock, scm_cond_wait, scm_cond_timedwait):
3504 Removed accidental #if 0 around these functions.
3506 These changes are the start of support for preemptive
3507 multithreading. Marius and I have agreed that I commit this code
3508 into the repository although it isn't thoroughly tested and surely
3509 introduces many bugs. The bugs should only be exposed when using
3510 threads, though. Signalling and error handling for threads is
3511 very likely broken. Work on making the implementation cleaner and
3512 more efficient is needed.
3514 * __scm.h (SCM_ALLOW_INTS_ONLY): Removed.
3515 (SCM_NONREC_CRITICAL_SECTION_START,
3516 SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START,
3517 SCM_REC_CRITICAL_SECTION_END): New macros.
3518 (SCM_CRITICAL_SECTION_START/END): Defined here.
3520 * eval.c: Insert SOURCE_SECTION_START / SOURCE_SECTION_END around
3521 the three calls to scm_m_expand_body.
3523 * gc.h: #include "libguile/pthread-threads.h";
3524 (SCM_FREELIST_CREATE, SCM_FREELIST_LOC): New macros.
3526 * gc.c (scm_i_freelist, scm_i_freelist2): Defined to be of type
3529 * gc.c, gc-freelist.c, inline.h: Use SCM_FREELIST_LOC for freelist
3532 * gc-freelist.c (scm_gc_init_freelist): Create freelist keys.
3534 * gc-freelist.c, threads.c (really_launch): Use
3535 SCM_FREELIST_CREATE.
3537 * gc-malloc.c (scm_realloc, scm_gc_register_collectable_memory):
3539 * gc.c (scm_i_expensive_validation_check, scm_gc,
3540 scm_gc_for_newcell): Put threads to sleep before doing GC-related
3541 heap administration so that those pieces of code are executed
3542 single-threaded. We might consider rewriting these code sections
3543 in terms of a "call_gc_code_singly_threaded" construct instead of
3544 calling the pair of scm_i_thread_put_to_sleep () and
3545 scm_i_thread_wake_up (). Also, we would want to have as many of
3546 these sections eleminated.
3548 * init.c (scm_init_guile_1): Call scm_threads_prehistory.
3550 * inline.h: #include "libguile/threads.h"
3552 * pthread-threads.h: Macros now conform more closely to the
3553 pthreads interface. Some of them now take a second argument.
3555 * threads.c, threads.h: Many changes.
3557 2002-12-09 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3559 * Makefile.am (version.h): Changed $^ --> $< in rule for
3562 2002-12-08 Rob Browning <rlb@defaultvalue.org>
3564 * version.h.in (SCM_MICRO_VERSION): use @--@ substitution now.
3565 (SCM_MINOR_VERSION): use @--@ substitution now.
3566 (SCM_MICRO_VERSION): use @--@ substitution now.
3567 (scm_effective_version): new function prototype.
3569 * version.c (scm_effective_version): new function, also add
3572 * Makefile.am (schemelibdir): VERSION -> GUILE_EFFECTIVE_VERSION.
3573 (libpath.h): use GUILE_EFFECTIVE_VERSION to compute
3575 (version.h): generate this here rather than configure.in. This
3576 approach tracks source edits better (i.e. more immediately).
3577 Might be worth considering for other .in files too.
3579 2002-12-02 Marius Vollmer <mvo@zagadka.ping.de>
3581 Reorganized thread package selection. A thread package now only
3582 implements a small set of pthread like functions and Guile
3583 implements the rest on top of that. Guile's implementation is
3584 what the "coop-pthreads" package has been previously. Support for
3585 "coop" threads has been removed until I get time to add it again.
3587 * Makefile.am (libguile_la_SOURCES): Removed iselect.c.
3588 (noinst_HEADERS): Removed coop-threads.c, coop-threads.h, coop.c,
3589 null-threads.c, coop-pthreads.c.
3590 (modinclude_HEADERS): Removed coop-defs.h, coop-pthreads.h. Added
3593 * validate.h (SCM_VALIDATE_THREAD): Moved to threads.h.
3595 * threads.h: Do not include "libguile/coop-defs.h". Include
3596 "libguile/pthread-threads.h" for USE_COPT_THREADS. Removed
3597 (previously deprecated) C level thread API prototypes. They are
3598 now in the thread package specific headers, "null-threads.h" and
3599 "pthread-threads.h".
3600 (SCM_VALIDATE_THREAD, SCM_VALIDATE_MUTEX, SCM_VALIDATE_CONDVAR):
3602 (scm_threads_init): Removed.
3603 (SCM_CRITICAL_SECTION_START, SCM_CRITICAL_SECTION_END,
3604 SCM_THREAD_SWITCHING_CODE, scm_i_switch_counter,
3605 SCM_I_THREAD_SWITCH_COUNT): Define here.
3606 (scm_single_thread_p): Removed.
3607 (scm_call_with_new_thread): Take two args directly instead of list
3609 (scm_i_thread_data, scm_i_set_thread_data, SCM_THREAD_LOCAL_DATA,
3610 SCM_SET_THREAD_LOCAL_DATA): Define here.
3612 * threads.c: Merged with "coop-pthreads.c".
3614 * null-threads.h: Implement pthread-like API as a set of macros.
3616 * pthread-threads.h: New, implement pthread-like API by deferring
3619 * init.c (scm_init_guile_1): Do not call scm_init_iselect, which
3620 has been lost in the reorganization.
3622 2002-12-01 Mikael Djurfeldt <mdj@linnaeus>
3624 The following change makes it possible to move procedure
3625 application dispatch outside inner loops. The motivation was
3626 clean implementation of efficient replacements of R5RS primitives
3629 The semantics is clear: scm_trampoline_N returns an optimized
3630 version of scm_call_N (or NULL if the procedure isn't applicable
3633 Applying the optimization to map and for-each increases efficiency
3634 noticeably. For example, (map abs ls) is 8 times faster than
3637 * eval.h (scm_t_trampoline_1, scm_t_trampoline_2): New types.
3639 * eval.c, eval.h (scm_trampoline_1, scm_trampoline_2): New functions.

4150 * gc-malloc.c (scm_calloc): try to use calloc() before calling
4153 * gc-segment.c (scm_i_initialize_heap_segment_data): remove card
4154 init loop; handle this from scm_init_card_freelist()
4156 * gc-card.c (scm_init_card_freelist): init bit vector here.
4158 * numbers.c (scm_make_real): prevent reordering of statements
4159 num2float.i.c (FLOAT2NUM): idem
4161 2002-08-27 Han-Wen Nienhuys <hanwen@cs.uu.nl>
4163 * eval.h: prepend libguile/ to include path
4165 2002-08-26 Marius Vollmer <mvo@zagadka.ping.de>
4167 * script.c (scm_compile_shell_switches): Added "2002" to Copyright
4168 years. Thanks to Martin Grabmüller!
4170 2002-08-25 Han-Wen Nienhuys <hanwen@cs.uu.nl>
4172 * gc-segment.c (scm_i_get_new_heap_segment): use float in stead of
4173 unsigned numbers for computing minimum heap increment. This
4174 prevents weird results when a a negative minimum increment is
4177 2002-08-24 Marius Vollmer <mvo@zagadka.ping.de>
4179 * gc_os_dep.c: When we have __libc_stack_end, use that directly
4180 instead of the old tricks.
4182 * guile-snarf.in: Do not expect the input file to be the first
4183 argument after the optional "-o" option, just pass everything to
4184 the pre-processor without extracting the input file name.
4186 2002-08-23 Han-Wen Nienhuys <hanwen@cs.uu.nl>
4188 * gc-segment.c (scm_i_get_new_heap_segment): Oops. We want segment
4189 length *at* least SCM_MIN_HEAP_SEG_SIZE, not at most.
4191 2002-08-22 Han-Wen Nienhuys <hanwen@cs.uu.nl>
4193 * gc.h, gc.c: make scm_cells_allocated unsigned again. Thanks to
4194 Bill Schottstaedt for the bug report
4196 2002-08-20 Marius Vollmer <mvo@zagadka.ping.de>
4198 * print.c (scm_iprin1): Print primitives generics always as
4199 "primitive-generic" even when they have no primitive methods yet.
4201 2002-08-17 Gary Houston <ghouston@arglist.com>
4203 * coop.c (coop_create): removed bogus 2nd argument in scm_malloc
4206 2002-08-17 Han-Wen Nienhuys <hanwen@cs.uu.nl>
4208 * ports.c (scm_add_to_port_table): small bugfix.
4210 * mallocs.c (scm_malloc_obj): use scm_gc_malloc in stead of
4213 * gc-segment.c (scm_i_get_new_heap_segment): remove cluster cruft:
4214 only use SCM_MIN_HEAP_SEG_SIZE.
4216 * ports.c (scm_add_to_port_table): add backwards compatibility
4219 * ports.h: use scm_i_ prefix for port table and port table size.
4221 2002-08-15 Mikael Djurfeldt <mdj@linnaeus>
4223 * vports.c (scm_make_soft_port): Initialize pt variable.
4225 2002-08-13 Marius Vollmer <mvo@zagadka.ping.de>
4227 * strports.h (scm_c_eval_string_in_module,
4228 scm_eval_string_in_module): New prototypes.
4229 * strports.c (scm_eval_string_in_module): New, but use
4230 "eval-string" as the Scheme name and make second parameter
4232 (scm_eval_string): Implement using scm_eval_string_in_module.
4233 (scm_c_eval_string_in_module): New.
4234 Thanks to Ralf Mattes for the suggestion!
4236 2002-08-09 Han-Wen Nienhuys <hanwen@cs.uu.nl>
4238 * gc-card.c ("sweep_card"): remove SCM_MISC_ERROR messages: print
4241 * gc-mark.c ("scm_gc_mark_dependencies"): idem.
4243 * ports.c ("scm_new_port_table_entry"): return a boxed SCM in
4244 stead of scm_t_port*. The function now takes a tag argument.
4246 2002-08-08 Han-Wen Nienhuys <hanwen@cs.uu.nl>
4248 * gc.h: add scm_debug_cells_gc_interval to public interface
4250 * gc-card.c ("sweep_card"): set scm_gc_running while sweeping.
4252 * gc.c (scm_i_expensive_validation_check): separate expensive
4253 validation checks from cheap ones.
4255 2002-08-06 Han-Wen Nienhuys <hanwen@cs.uu.nl>
4257 * read.c (scm_input_error): new function: give meaningful error
4258 messages, and throw read-error
4260 * gc-malloc.c (scm_calloc): add scm_calloc.
4262 2002-08-05 Han-Wen Nienhuys <hanwen@cs.uu.nl>
4264 * tags.h: remove GC bits documentation from the tags table.
4266 * read.c (INPUT_ERROR): Prepare for file:line:column error
4267 messages for errors in scm_lreadr() and friends.
4269 2002-08-04 Han-Wen Nienhuys <hanwen@cs.uu.nl>
4271 * gc-malloc.c (scm_malloc): use scm_realloc() (simplifies
4273 (scm_gc_calloc): new function
4275 2002-08-04 Han-Wen Nienhuys <hanwen@cs.uu.nl>
4277 * ports.c (scm_new_port_table_entry): init port entry to 0
4280 * ports.c (scm_new_port_table_entry): change function from
4281 scm_add_to_port_table. This prevents cells with null-pointers from
4282 being exposed to GC.
4284 * vports.c (scm_make_soft_port) strports.c (scm_mkstrport),
4285 fports.c (scm_fdes_to_port): Use scm_new_port_table_entry().
4287 * gc.c (scm_gc_stats): add cell-yield and malloc-yield statistic
4290 * numbers.c (big2str): return "0" for 0 iso. ""
4292 * gc-segment.c, gc-malloc.c gc-mark.c, gc-freelist.c, gc-card.c,
4293 private-gc.h: new file
4295 * gc.c: completely revised and cleaned up the GC. It now uses lazy
4296 sweeping. More documentation in workbook/newgc.text
4298 2002-07-25 Marius Vollmer <marius.vollmer@uni-dortmund.de>
4300 * random.c (rstate_free): Return zero.
4302 2002-07-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
4304 * environments.c (remove_key_from_alist): Removed.
4306 (obarray_remove): Simplified.
4308 2002-07-24 Stefan Jahn <stefan@lkcc.org>
4310 * continuations.h: ia64: Include <signal.h> before
4313 2002-07-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
4315 * modules.c (scm_sym2var): Don't compare SCM values with ==.
4317 2002-07-21 Han-Wen Nienhuys <hanwen@cs.uu.nl>
4319 * goops.c (scm_compute_applicable_methods): use
4320 scm_remember_upto_here_1 iso scm_remember_upto_here
4322 * macros.c: include deprecation.h
4324 * vectors.c (scm_vector_move_right_x): remove side effect in
4326 (scm_vector_move_left_x): idem.
4328 * net_db.c, posix.c, socket.c: variable naming: change ans to
4331 * sort.c (scm_merge_vector_x): accept vector as argument
4332 iso. SCM*. This is needed for full GC correctness.
4334 * gc.h: undo previous undocumented changes related to #ifdef
4337 2002-07-20 Han-Wen Nienhuys <hanwen@cs.uu.nl>
4339 * *.c: add space after commas everywhere.
4341 * *.c: use SCM_VECTOR_SET everywhere, where a vector is written.
4342 Document cases where SCM_WRITABLE_VELTS() is used.
4344 * vectors.h (SCM_VELTS): prepare for write barrier, and let
4345 SCM_VELTS() return a const pointer
4346 (SCM_VECTOR_SET): add macro.
4348 2002-07-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
4350 * eval.c (SCM_CEVAL), macros.c (macro_print, scm_makmacro,
4351 scm_sym_macro, scm_macro_type), macros.h (scm_makmacro):
4352 Deprecated the special kind of built-in dynamic syntax transformer
4353 that was inaccurately named "macro". Note: The built-in syntax
4354 transformers that are named "mmacro" or "memoizing-macro" still
4355 exist, and it is these which come much closer to what one would
4358 2002-07-13 Neil Jerram <neil@ossau.uklinux.net>
4360 * eval.c (unmemocopy): Fix for
4361 1001-local-eval-error-backtrace-segfaults (unmemoization crash
4362 with internal definitions and local-eval).
4364 2002-07-12 Gary Houston <ghouston@arglist.com>
4366 * dynl.c: Don't define stub procedures if DYNAMIC_LINKING is not
4367 defined. They don't do anything useful, especially since the
4368 only case where DYNAMIC_LINKING is undefined seems to be
4369 when --with-modules=no is given to configure, which is basically
4370 requesting that the "dynamic linking module" be omitted.
4372 * Makefile.am (libguile_la_SOURCES): move dynl.c from
4373 libguile_la_SOURCES to EXTRA_libguile_la_SOURCES.
4375 * extensions.c (load_extension): check DYNAMIC_LINKING for
4377 * init.c (scm_init_guile_1): check DYNAMIC_LINKING for
4378 scm_init_dynamic_linking.
4380 2002-07-10 Marius Vollmer <mvo@zagadka.ping.de>
4382 * guile.c, iselect.h, net_db.c, posix.c, socket.c: No need to
4383 check for Cygwin when including <winsock2.h>, this is already
4384 check for by configure. Thus, revert change from 2002-07-07.
4386 2002-07-10 Gary Houston <ghouston@arglist.com>
4388 * eq.c: include <string.h>
4389 * dynl.c: docstring editing.
4391 2002-07-09 Gary Houston <ghouston@arglist.com>
4393 * dynl.c (scm_dynamic_call): docstring editing.
4395 2002-07-08 Rob Browning <rlb@defaultvalue.org>
4397 * gc_os_dep.c: HURD fixes.
4399 2002-07-07 Marius Vollmer <mvo@zagadka.ping.de>
4401 Crosscompiling and Cygwin fixes by Jan Nieuwenhuizen. Thanks!
4403 * Makefile.am: Override default rule for c-tokenize.$(OBJECT);
4404 this should be compiled for BUILD host.
4405 Override default rule for
4406 guile_filter_doc_snarfage$(EEXECT); this should run on BUILD host.
4407 Add missing $(EXEEXT) to guile_filter_doc_snarfage invocation.
4408 (snarf2checkedtexi): Use GUILE_FOR_BUILD instead of preinstguile.
4410 * guile.c, iselect.h, net_db.c, posix.c, socket.c: Do not include
4411 <winsock2.h> on Cygwin even when we have it.
4413 2002-07-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
4415 * __scm.h (SCM_CAUTIOUS), eval.c (scm_eval_args, deval_args,
4416 SCM_CEVAL): Removed compile time option SCM_CAUTIOUS to clean up
4417 the code. Full number of arguments checking of closures is
4418 mandatory now. However, the option to disable the checking has
4419 most probably not been used anyway.
4421 2002-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
4423 * __scm.h (SCM_RECKLESS), backtrace.c (SCM_ASSERT), debug.c
4424 (scm_debug_options), eval.c (scm_lookupcar, scm_lookupcar1,
4425 scm_badargsp, SCM_CEVAL, SCM_APPLY, scm_map, scm_for_each),
4426 feature.c (scm_init_feature), gsubr.c (scm_gsubr_apply), numbers.c
4427 (scm_logand, scm_logior, scm_logxor, scm_i_dbl2big), srcprop.c
4428 (scm_source_properties, scm_set_source_properties_x,
4429 scm_source_property): Removed compile time option SCM_RECKLESS to
4430 clean up the code. Full number of arguments checking of closures
4431 is mandatory now. However, the option to disable the checking has
4432 most probably not been used anyway.
4434 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
4435 scm_source_property): Use !SCM_CONSP instead of SCM_NCONSP.
4437 2002-06-30 Gary Houston <ghouston@arglist.com>
4439 * dynl.c: Removed all SCM_DEFER_INTS/SCM_ALLOW_INTS, which won't
4440 do anything useful. Added a comment about need for a mutex if
4441 pre-emptive threading is supported.
4443 * posix.c (scm_convert_exec_args), dynl.c
4444 (scm_make_argv_from_stringlist): static procs: 1) renamed both to
4445 allocate_string_pointers. 2) simplified: don't reallocate the
4446 strings, just make an array of pointers 3) avoid memory leaks on
4447 error 4) let the procedure report errors in its own name.
4448 Consequences: 1) the procedures now assume that SCM strings are
4449 nul-terminated, which should always be the case. 2) Since strings
4450 are not reallocated, it's now possible for strings passed to
4451 dynamic-args-call to be mutated.
4453 2002-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
4455 * __scm.h, eval.c, eval.h: Removed compile time option
4456 MEMOIZE_LOCALS to clean up the code. Now, caching of local
4457 variable positions during memoization is mandatory. However, the
4458 option to disable the caching has most probably not been used
4461 2002-06-18 Marius Vollmer <mvo@zagadka.ping.de>
4463 * print.c (scm_simple_format): Print missing part of format before
4464 ~% control. Thanks to Daniel Skarda!
4466 2002-06-01 Marius Vollmer <mvo@zagadka.ping.de>
4468 * mkstemp.c: Added exception notice to license statement.
4470 2002-05-22 Marius Vollmer <mvo@zagadka.ping.de>
4472 * numbers.c (mem2ureal): When returning an inexact zero, make sure
4473 it is represented as a floating point value so that we can change
4476 From John W. Eaton <jwe@bevo.che.wisc.edu>
4478 * numbers.c (idbl2str): Don't omit sign when printing negative zero.
4480 2002-05-14 Thien-Thi Nguyen <ttn@giblet.glug.org>
4482 * gc_os_dep.c: For I386/OPENBSD, allow for `__i386__'
4483 in addition to `i386'. Thanks to Dale P. Smith.
4485 2002-05-08 Marius Vollmer <mvo@zagadka.ping.de>
4487 * eq.c (real_eqv): New.
4488 (scm_eqv_p): Use it when comparing reals and complexes.
4490 * numbers.c: Include <string.h>, for strncmp.
4491 (mem2complex): Do not create negative NaNs.
4492 (scm_leq_p, scm_geq_p): Explicitely return #f when comparing a
4494 (scm_inexact_to_exact): Signal error when converting a NaN.
4496 2002-05-06 Marius Vollmer <mvo@zagadka.ping.de>
4498 * posix.c (scm_putenv): Handle removing variables explicitely by
4503 * numbers.h: Conditionally include floatingpoint.h, ieeefp.h, and
4504 nan.h. Provide declarations for scm_inf_p, scm_nan_p, scn_inf,
4506 * numbers.c: [SCO && ! HAVE_ISNAN] (isnan): New function.
4507 [SCO && ! HAVE_ISINF] (isinf): New function.
4508 (xisinf, xisnan): New functions.
4510 (isfinite): Define in terms of xisinf.
4511 (scm_inf_p, scm_nan_p): New functions.
4512 (guile_Inf, guile_NaN): New file-scope vars.
4513 (guile_ieee_init): New function.
4514 (scm_inf, scm_nan): New functions.
4515 (idbl2str): Handle Inf and NaN. Remove funny label and
4516 corresponding gotos.
4517 (ALLOW_DIVIDE_BY_ZERO): New macro.
4518 (scm_divide): Allow division by zero to occur if
4519 ALLOW_DIVIDE_BY_ZERO is defined.
4520 Handle bignums and ints as special cases.
4522 Additional stuff by me:
4524 numbers.c (mem2ureal): Recognize "inf.0" and "nan.xxx".
4525 (scm_even_p, scm_odd_p): Treat infinity as even and odd.
4526 (iflo2str): Don't output a '+' for negative numbers or for Inf and
4527 NaN. They will provide their own sign.
4528 (scm_divide): Only allow divides by inexact zeros. Dividing by
4529 exact zeros still signals an errors.
4531 2002-04-22 Thien-Thi Nguyen <ttn@giblet.glug.org>
4533 * goops.h (scm_slot_exists_p): Rename from scm_slots_exists_p.
4534 * goops.c (scm_slot_exists_p): Rename from scm_slots_exists_p.
4535 (scm_slot_exists_p): Rename from scm_slots_exists_p.
4536 Thanks to Andreas Rottmann.
4538 2002-04-20 Gary Houston <ghouston@arglist.com>
4540 * removal of unused fields in root state (thanks to Christopher
4541 Cramer for pointing out the disuse.)
4542 * root.h (scm_root_state): removed def_inp, def_outp, def_errp.
4543 (scm_def_inp, scm_def_outp, scm_def_errp): removed.
4545 * root.c (root_mark): don't mark them.
4546 (scm_make_root): don't set them to #f.
4547 * init.c (scm_init_standard_ports): don't initialise with the
4550 2002-04-17 Marius Vollmer <mvo@zagadka.ping.de>
4552 * Makefile.am (EXTRA_DIST): Added cpp_err_symbols.c and
4555 2002-04-16 Marius Vollmer <mvo@zagadka.ping.de>
4557 * guile-snarf.in: Do not clean input file. This would write to
4558 the $(srcdir) during a VPATH build, which is not allowed. It also
4559 isn't needed since it only works when an output filename has been
4560 specified and in that case we don't need to clean the input file
4561 because the output file will already exist.
4563 2002-03-31 Marius Vollmer <mvo@zagadka.ping.de>
4565 * guile-snarf: Install the trap for removing $cleanfile only when
4566 the value of $cleanfile is actually known.
4568 2002-04-10 Rob Browning <rlb@defaultvalue.org>
4570 * .cvsignore: add versiondat.h and *.c.clean.c.
4572 2002-03-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
4574 * srcprop.[ch] (scm_c_source_property_breakpoint_p): New
4575 function, replaces macro SRCBRKP.
4577 (SRCBRKP): Deprecated.
4579 * eval.c (SCM_CEVAL): Replaced use of SRCBRKP by call to
4580 scm_c_source_property_breakpoint_p. Removed some use of arg1 as
4583 2002-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
4585 * debug.h, eval.c: Deprecated CHECK_ENTRY, CHECK_APPLY and
4586 CHECK_EXIT and removed all references to them.
4588 2002-03-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
4590 * debug.h (scm_ready_p, debug_print): Removed declarations.
4592 * eval.c (EVALCELLCAR): Removed.
4594 (SCM_CEVAL): Eliminated label loopnoap. Removed side-effecting
4595 operation from condition.
4597 2002-03-24 Marius Vollmer <mvo@zagadka.ping.de>
4599 * guile-snarf.in: When the output filename is "-", write to
4600 stdout. When no "-o" option is given, use "-" as the output
4601 filename (i.e., stdout). Only 'clean' the inputfile or remove the
4602 output file on error when the output file name is not "-". Define
4603 the preprocessor macro SCM_MAGIC_SNARFER while snarfing.
4605 * Makefile.am (.c.x): Pass "-o $@" to guile-snarf.
4607 2002-03-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
4609 * eval.c (SCM_CEVAL, SCM_APPLY): Eliminated labels wrongnumargs
4610 and the corresponding goto statements. Removed redundant code.
4612 2002-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
4614 * eval.c (SCM_CEVAL): Minimized scope of variable arg2.
4615 Eliminated redundant SCM_IMP check. Exlined call to EVALCAR.
4616 Re-enabled handing of rpsubrs and asubrs.
4618 2002-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
4620 * eval.c (SIDEVAL): Removed.
4622 (SCM_CEVAL): Minimized scope of variable orig_sym. Eliminated
4623 goto-labels cdrxnoap, cdrxbegin and nontoplevel_cdrxnoap. Changed
4624 argument checking order for set! to locals, variables and symbols.
4625 Improvements to control structure. Removed some uses of arg1 and
4626 arg2 as temporary variables.
4628 2002-03-15 Thien-Thi Nguyen <ttn@giblet.glug.org>
4630 * guile-snarf.in: Remove "--compat=1.4" support.
4631 Add "-d" and "-D" support.
4633 (deprecated_list): New var.
4634 (compat_mode_clean_xxx): Delete.
4635 (grep_deprecated): New func.
4636 ("main"): If "-d" or "-D", call `grep_deprecated'.
4638 2002-03-15 Neil Jerram <neil@ossau.uklinux.net>
4640 * hooks.h: Change scm_t_c_hookype_t everywhere to
4645 * strings.c (scm_string_p): Change unnecessary `iff' to `if'.
4647 * ports.c (scm_sys_make_void_port): Use `@file'.
4649 * numbers.c (scm_number_p, scm_real_p): Use `otherwise' rather
4652 * macros.c (scm_makmacro): Don't say that the form replaces its
4653 source, because it doesn't.
4654 (scm_makmmacro): Clarify difference between this and scm_makmacro.
4656 * backtrace.c (scm_display_error), filesys.c (scm_umask,
4657 scm_select, scm_basename), goops.c (scm_method_generic_function),
4658 numbers.c (scm_integer_length), posix.c (scm_getgroups, scm_execl,
4659 scm_setlocale, scm_flock), socket.c (scm_shutdown): Correct
4662 * debug.c (scm_debug_options), eval.c
4663 (scm_eval_options_interface), read.c (scm_read_options): Change
4664 incorrect @var in docstring to @code.
4666 2002-03-14 Marius Vollmer <mvo@zagadka.ping.de>
4668 * unif.c (singp): Use SCM_REALP instead of SCM_SLOPPY_REALP.
4670 * snarf.h (SCM_SNARF_INIT): Add "^:^" after code so that
4671 guile-snarf can remove trailing non-init code.
4673 * guile-snarf.in (modern_snarf): Remove everything following and
4674 including "^:^" from the output.
4676 2002-03-14 Dirk Herrmann <D.Herrmann@tu-bs.de>
4678 * eval.c (SCM_CEVAL), srcprop.h (SRCBRKP): Eliminated union 't'.
4680 * eval.c (SCM_CEVAL): Exlined call to EVALCAR.
4682 2002-03-13 Thien-Thi Nguyen <ttn@giblet.glug.org>

4709 2002-03-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
4711 * eval.c (SCM_CEVAL): Got rid of the last reference to t.lloc.
4712 The next step will be to remove the union 't' and simplify the

4731 2002-03-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
4733 * eval.c (SCM_CEVAL): Cleaned up the handling of 'slot-ref',
4734 'slot-set!' and 'nil-cond'. Removed some uses of t.arg1, arg2 and
4735 proc as temporary variables. Introduced temporary variables with

4744 arg2. Removed some uses of t.arg1, t.lloc and proc as temporary
4745 variables. Introduced temporary variables with hopefully
4746 descriptive names for clarification. Replaced SCM_N?IMP by a more
4747 explicit predicate in some places. Use SCM_INSTANCE_HASH instead
4748 of computing the expression explicitly. Eliminate now unused

4768 of SCM_MAX_FRAME_SIZE as a bit mask; it isn't used like this.
4770 * eval.c (SCM_CEVAL): Don't store scm_debug_eframe_size in
4771 debug.status. It isn't needed, and it can overflow the bits
4772 reserved for it (which may lead to a segv or a GC abort).

4791 conditions and macro calls. Introduced temporary variables with
4792 hopefully descriptive names for clarification. Replaced SCM_N?IMP
4793 by a more explicit predicate in some places. Removed code that
4794 was conditionally compiled if SICP was defined - which it never
4797 2002-03-02 Dirk Herrmann <D.Herrmann@tu-bs.de>

4802 Introduced temporary variables with hopefully descriptive names
4803 for clarification. Replaced SCM_N?IMP by a more explicit
4804 predicate in some places.

5240 2001-11-21 Gary Houston <ghouston@arglist.com>
5242 * Makefile.am (OMIT_DEPENDENCIES): removed, since it seems to be
5243 obsolete. autogen.sh says:
5244 invalid unused variable name: `OMIT_DEPENDENCIES'
5246 2001-11-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
5248 * numbers.c (scm_divide): Fix (/ 0). Thanks to Keith Wright for

5292 (SCM_MICRO_VERSION): renamed from SCM_GUILE_MICRO_VERSION.
5294 2001-11-18 Neil Jerram <neil@ossau.uklinux.net>
5296 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
5297 Rewrite docstrings without reference to substring-move-left/right,
5298 since the latter no longer exist.
5300 2001-11-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
5302 * eval.c: Removed bogus comment about acros.
5304 (scm_unmemocar): Use !SCM_CONSP instead of SCM_IMP.

5306 macro DEBUG_EXTENSIONS.
5308 (s_splicing): New error message string.

5311 expression' message.
5313 (scm_m_quote): Eliminate unnecessary copying.
5315 (scm_m_lambda, scm_m_letstar, scm_m_letrec, scm_m_let): Leave the
5316 checking of the body to scm_m_body.
5318 (scm_m_do): Move comment to function header. Rename arg1 to
5319 binding. Made the code a bit easier to read.
5323 (iqq): Added a comment. Changed the depth parameter to
5324 unsigned. Use size_t for vector lengths. Make sure vector object
5325 is gc protected as long as its contents are read. Add some syntax
5326 checks. Get rid of unnecessary SCM_IMP test. Clean up the
5327 control structure a bit.
5329 (scm_m_delay): Added comment about the implementation of
5332 (scm_m_define): Add comment about guile's currying define
5333 syntax. Renamed 'proc' to 'name'. Eliminate dependency on macro
5334 DEBUG_EXTENSIONS. Simplified code a bit. Eliminate SICP code.
5336 (scm_m_letrec1): Removed. Part of the functionality is taken
5337 over by the new function 'transform_bindings'.
5339 (transform_bindings): New function. Takes over some of the
5340 functionality of removed function 'scm_m_letrec1', namely to split
5341 a list of bindings into a reversed list of variables and a list of
5344 (scm_m_letrec): Call 'transform_bindings'.
5346 (scm_m_let): Minimized scope of local variables. Renamed 'proc'
5347 to 'temp' and 'arg1' to 'binding'. Eliminated redundant SCM_NIMP
5348 test. Use 'transform_bindings'. Fixed scoping error with named
5349 let (Thanks to Aubrey Jaffer for reporting the bug and to Neil
5350 Jerram for suggesting the fix). Cleaned up the control structure
5353 (scm_m_expand_body): Use 'transform_bindings'. Eliminated
5354 unnecessary consing. Eliminated unnecessary
5355 SCM_DEFER/ALLOW_INTS.
5357 (SCM_CEVAL): Un-obfuscated some loops.
5359 2001-11-16 Neil Jerram <neil@ossau.uklinux.net>
5361 * gc.h (scm_unhash_name): Old declaration removed.
5363 * eval.c (s_scm_eval): Change @var{primitive-eval} to
5364 @code{primitive-eval}.
5366 * feature.c, vectors.c, net_db.c, unif.c, weaks.c, struct.c,
5367 version.c, alist.c, ports.c, ramap.c, unif.c, strings.c, list.c:
5368 Change @deffnx lines in docstrings to say {Scheme Procedure}
5369 rather than primitive or procedure.
5371 * posix.c (scm_execl), filesys.c (scm_close), unif.c
5372 (scm_array_set_x, scm_array_contents, scm_uniform_array_read_x,
5373 scm_bit_set_star_x, scm_bit_invert_x), ramap.c (scm_array_fill_x,
5374 scm_array_for_each, scm_array_index_map_x), vectors.c (scm_vector,
5375 scm_make_vector, scm_vector_to_list, scm_vector_fill_x), strop.c
5376 (scm_string_split, scm_string_ci_to_symbol), strings.c
5377 (scm_string_p), sort.c (scm_merge), print.c (scm_newline),
5378 macros.c (scm_macro_type), alist.c (scm_acons, scm_assq):
5379 Docstring fixes and improvements reflecting edits that have been
5380 made in the reference manual source.
5382 * objprop.c (scm_object_properties, scm_set_object_properties_x,
5383 scm_object_property, scm_set_object_property_x): Remove invalid
5384 @deffnx lines for corresponding procedure property primitives.
5386 These changes add a @deffnx C function declaration and function
5387 index entries for each Guile primitive to the copy of the doc
5388 snarf output that is used for reference manual synchronization.
5389 Online help is unchanged.
5391 * snarf.h (SCM_SNARF_DOCS): Output primitive's C function name.
5392 (SCM_DEFINE, SCM_DEFINE1, SCM_REGISTER_PROC): Supply to C function
5393 name to SCM_SNARF_DOCS.
5395 * guile-snarf-docs-texi.in: Pass the shell script's arguments into
5396 snarf-check-and-output-texi.
5398 * Makefile.am (guile-procedures.texi): New rule.
5399 (BUILT_SOURCES, guile.texi, guile-procedures.txt, CLEANFILES):
5400 Changed so that the last stage of doc snarfing is now performed
5401 twice, once to produce guile-procedures.txt for online help, and
5402 once to produce guile.texi for reference manual synchronization.
5404 2001-11-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
5406 * eval.c (RETURN): Wrap in do{}while(0) in order to make it
5407 safely usable as a single statement followed by a ';', for example
5410 (SCM_CEVAL, SCM_APPLY): Clean up code using 'RETURN'.
5412 2001-11-13 Neil Jerram <neil@ossau.uklinux.net>
5414 * random.c (scm_random_solid_sphere_x,
5415 scm_random_hollow_sphere_x): Correct "shere" typos.

5428 scm_substring_move_right_x): Removed.
5430 * __scm.h (HAVE_UINTPTR_T, HAVE_PTRDIFF_T, HAVE_LONG_LONG,
5431 HAVE_LONG_LONGS): Define to "1" when defining them, to mirror what
5434 2001-11-12 Marius Vollmer <mvo@zagadka.ping.de>
5436 * numbers.c: Document macros to define when including
5437 num2integral.i.c. MAX_VALUE and MIN_VALU are no longer used, we
5438 now rely on SIZEOF_ macros that have been figured out at
5441 * num2integral.i.c: Adapt to new interface.
5442 (NUM2INTEGRAL): Test whether a fixnum can be represented in the
5443 target type by casting it and checking whether it is still the
5444 same. Do not try to handle bignums for integral types that are
5445 smaller than fixnums. When handling bignums, collect the
5446 magnituse first into a unsigned type, and correctly check for
5448 (INTEGRAL2BIG): Do not use MIN_VALUE explicitely by observing that
5449 only -MIN_VALUE can still be negative of all negative numbers (in
5452 * tags.h (SIZEOF_SCM_T_BITS): Define it appropriately.
5454 * __scm.h: Define HAVE_UINTPTR_T, HAVE_PTRDIFF_T and
5455 HAVE_LONG_LONG depending on whether their size is non-zero.
5457 2001-11-11 Thien-Thi Nguyen <ttn@glug.org>
5459 * strop.c (scm_string_null_p): Docfix; nfc.

5470 filesys.c (scm_open, scm_lstat), struct.c
5471 (scm_make_struct_layout), random.c (scm_random,
5472 scm_random_solid_sphere_x, scm_random_hollow_sphere_x, strop.c
5473 (scm_i_index): Remove superfluous whitespace from end of docstring

5477 strings.c (scm_make_string), variable.c (scm_make_variable,
5478 scm_make_undefined_variable, scm_variable_p, scm_variable_set_x,
5479 scm_variable_bound_p), scmsigs.c (scm_setitimer, scm_getitimer),
5480 posix.c (scm_crypt), struct.c (scm_make_vtable_vtable), hashtab.c
5481 (scm_hash_fold), ports.c (scm_port_for_each): Remove superfluous
5482 newline at end of docstrings.
5484 * modules.c (scm_set_current_module): Add missing newline to
5487 2001-11-07 Stefan Jahn <stefan@lkcc.org>
5489 * win32-socket.[ch]: New files. Defines Winsock-API error codes
5490 and makes them available through Guile. That is because the
5491 Winsock-API does not store its errors in `errno' and thus cannot
5492 return error messages via `strerror (errno)'.
5494 * socket.c (scm_init_socket): Initialize `win32-socket' part
5495 here under M$-Windows.
5497 * numbers.h: Added missing declaration of
5498 `scm_sys_check_number_conversions()'.
5500 * error.c: Local definition of SCM_I_STRERROR and SCM_I_ERRNO
5501 and use in `(strerror)' and `(system-error)'.
5503 * Makefile.am (EXTRA_libguile_la_SOURCES): Added
5504 `win32-socket.[ch]' to extra source and header files.
5506 2001-11-06 Marius Vollmer <mvo@zagadka.ping.de>
5508 * script.c (scm_shell_usage, scm_compile_shell_switches): Prepend
5509 a call to turn-on-debugging when --debug has been given instead of
5510 turning it on directly. Also, handle new `--no-debug' option,
5511 which might suppress the call to turn-on-debugging.
5513 2001-11-05 Stefan Jahn <stefan@lkcc.org>
5515 * struct.c (s_scm_struct_vtable_p): Corrected docstring.
5517 2001-11-04 Stefan Jahn <stefan@lkcc.org>
5519 * Makefile.am (libguile_la_LIBADD): Added $(THREAD_LIBS_LOCAL)
5520 here (was at guile_LDADD) which describes the dependency
5521 correctly and allows a clean build on Win32.
5523 * __scm.h (SCM_API): Follow-up patch. Renamed __FOO__ macros
5526 * __scm.h: USE_DLL_IMPORT indicates the usage of the DLL
5527 import macros for external libraries (libcrypt, libqthreads,
5528 libreadline and libregex).
5530 * coop-defs.h: Include <winsock2.h> for `struct timeval'.
5532 * posix.c (flock): Added support for flock() in M$-Windows.
5534 * guile.c (SCM_IMPORT): Follow-up patch. Use SCM_IMPORT instead
5537 * fports.c (getflags): Differentiate reading and writing pipes
5540 * filesys.c (S_IS*): Redefine all of the S_IS*() macros for
5543 * coop.c (coop_condition_variable_timed_wait_mutex): Use
5544 conditionalized error code if `ETIMEDOUT' is not available.
5545 (scm_thread_usleep): Remove bogus declaration of `struct timeval
5548 * numbers.c (PTRDIFF_MIN): Moved this definition where it actually
5549 belongs. That is because NO_PREPRO_MAGIC gets undefined after
5550 each inclusion of `num2integral.i.c'.
5551 (SIZE_MAX): Define NO_PREPRO_MAGIC if SIZE_MAX is undefined.
5553 2001-11-03 Marius Vollmer <mvo@zagadka.ping.de>
5555 * eval.c (scm_m_begin): Allow `(begin)`, with no subforms.
5556 (SCM_CEVAL): Evaluate an empty `begin' to SCM_UNSPECIFIED.
5558 2001-11-02 Mikael Djurfeldt <mdj@linnaeus>
5560 * print.c (scm_iprin1): Mark print state as revealed when
5561 dispatching to generic write or display.
5563 * unif.c (scm_ra2contig): Fixed memory overwrite bug.
5565 2001-11-02 Marius Vollmer <mvo@zagadka.ping.de>
5567 Support for native Win32. Thanks to Stefan Jahn!
5569 * Makefile.am: Add win32-uname.c, win32-uname.h, win32-dirent.c
5570 and win32-dirent.h to extra source and header files. These
5571 include the uname() and the POSIX dirent interface implementation
5572 for M$-Windows. Put `-no-undefined' into LDFLAGS to support
5573 linkers which do not allow unresolved symbols inside shared
5574 libraries. Corrected `guile_filter_doc_snarfage$(EXEEXT)'
5577 * __scm.h: Defined SCM_API. This macro gets prepended to all
5578 function and data definitions which should be exported or imported
5579 in the resulting dynamic link library in the Win32 port.
5581 * __scm.h, alist.h, arbiters.h, async.h, backtrace.h, boolean.h,
5582 chars.h, continuations.h, coop-defs.h, coop-threads.h,
5583 debug-malloc.h, debug.h, deprecation.h, dynl.h, dynwind.h,

5594 tags.h, threads.h, throw.h, unif.h, values.h, variable.h, vectors.h,
5596 Prefixed each each exported symbol with SCM_API.
5598 * continuations.c: Added comment about the use of the extern
5599 declarations of {get,set}context() functions used in the ia64 port.
5601 * continuations.h, gc.c: `__libc_ia64_register_backing_store_base'
5602 is meant to be a `unsigned long *'.
5604 * filesys.c: Include `direct.h' if possible. Use local
5605 `win32-dirent.h' for the native M$-Windows port. Define S_IS*()
5606 macros for M$-Windows. Implementation of `fstat_Win32()' which is
5607 able to differentiate between sockets and other file descriptors.
5608 Use this function as wrapper in `scm_fstat()'. Fixed typo in
5611 * fports.c: Include `io.h' is possible. Put `*fp' into referring
5612 statement block in `scm_fport_buffer_add()'.
5613 Some corrections in `getflags()'.
5615 * gdb_interface.h (GDB_INTERFACE): Also support __CYGWIN__.
5617 * guile.c: Make sure to define __SCM_IMPORT__ for shared library
5618 build on Win32. Disable preloaded symbols on Win2 platforms.
5620 * ioext.c, ports.c: Include `io.h' is possible.
5622 * mkstemp.c: Include `process.h' is possible.
5624 * net_db.c: Disable extern declaration of `h_errno' for __CYGWIN__,
5626 Put `scm_return_entry()' into HAVE_GETSERVENT conditional.
5628 * posix.c: Remove unnecessary dirent includes and defines. Include
5629 local `win32-uname.h' for MinGW. Extern declaration of
5630 `mkstemp()' for systems where it does not exists. Make
5631 `getlogin()' available on M$-Windows.
5633 * scmsigs.c: Made `usleep()' avalable on MinGW.
5635 * stime.c: On M$-Windows `tzname[]' is known to be `_tzname[]'.
5637 * win32-dirent.c: Include "win32-dirent.h", not "dirent.h".
5639 * win32-uname.c: Include "win32-uname.h", not "uname.h".
5641 2001-10-28 Mikael Djurfeldt <mdj@linnaeus>
5643 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write):
5644 Don't apply scm_uniform_vector_length on arrays.
5646 2001-10-14 Dirk Herrmann <D.Herrmann@tu-bs.de>
5648 * eval.c (scm_lookupcar, scm_m_letstar, scm_m_do, iqq,
5649 scm_m_define, scm_m_letrec1, scm_m_let, scm_m_expand_body,
5650 scm_macroexp, unmemocopy, scm_eval_args, scm_deval_args,
5651 SCM_CEVAL, scm_map, scm_init_eval): When building lists, prefer
5652 scm_list_<n> over scm_cons[2]?.
5654 (scm_unmemocar, scm_m_cond, scm_m_letstar, scm_m_letrec1,
5655 scm_m_let, scm_m_atbind, unmemocopy, SCM_CEVAL, SCM_APPLY): Use
5656 SCM_C[AD][AD]R instead of explicit form.
5658 (scm_m_set_x, scm_m_cond, scm_m_letstar, scm_m_do): Reordered
5659 comparison parameters.
5661 (scm_m_case, scm_m_cond, scm_m_letstar, scm_m_do, SCM_CEVAL): Use
5662 !SCM_NULLP instead of SCM_NIMP.
5664 (scm_m_case): Don't copy the form. Renamed proc to clause and
5665 minimized its scope. Renamed x to clauses. Removed side
5666 effecting operation from macro call.
5668 (scm_m_cond): Don't copy the form. Renamed arg1 to clause and
5669 minimized its scope. Renamed x to clauses. Minimized the scope
5670 of variable 'len'. Make sure the else clause is treated specially
5671 even in case of '=>' occurences. Don't change the else to #t in
5672 order to be able to distinguish this case in the evaluator. Leave
5673 type checking of the recipient to the evaluator.
5675 (scm_c_improper_memq): Made the comment somewhat clearer.
5677 (scm_m_lambda): Renamed proc to formals. Removed unnecessary
5678 test for SCM_IM_LET at the place of the formal parameters.
5679 Simplified the formal parameter checking.
5681 (scm_m_letstar): Added Comment. Renamed proc to bindings.
5682 Renamed arg1 to binding and minimized its scope. Eliminated
5683 unnecessary consing.
5685 (scm_m_do): Renamed proc to bindings. Minimized the scope of
5688 (build_binding_list): New static function.
5690 (unmemocopy): Don't use SCM_TYP7 on pairs (it's unclean).
5691 Further, split up the 'letrec' unmemoizing code to the
5692 corresponding parts for 'do', 'let' and 'letrec', adding comments
5693 to each form. Cleanup the handling of the do form (This removes
5694 some *real* code :-).
5696 (SCM_CEVAL): Removed side effecting operation from macro call.
5697 Handle the 'else clause of the 'cond form specially - the symbol
5698 'else is not replaced with #t any more.
5700 2001-10-14 Gary Houston <ghouston@arglist.com>
5702 * version.c (scm_version): use sprintf instead of snprintf,
5703 for portability. thanks to Bill Schottstaedt.
5705 2001-10-14 Mikael Djurfeldt <mdj@linnaeus>
5707 * read.c (scm_lreadr): When user-defined hash procedure returns
5708 SCM_UNSPECIFIED: Fall back to standard handling instead of raising
5709 an exception. (This prevents parsing of uniform vectors from
5710 interfering with parsing of numbers.)
5712 2001-10-13 Marius Vollmer <mvo@zagadka.ping.de>
5714 * numbers.c: Set NO_PREPRO_MAGIC when defining our version of
5715 PTRDIFF_MIN. Thanks to Ken Raeburn.
5717 2001-10-07 Marius Vollmer <mvo@zagadka.ping.de>
5719 * Makefile.am (EXTRA_libguile_la_SOURCES): Added "mkstemp.c".
5721 * eval.c (scm_m_atbind): First try to find the variable without
5722 defining it locally; when it has not been found, define it
5725 * modules.c (module_variable): Pass over variables that exist but
5728 2001-10-06 Marius Vollmer <mvo@zagadka.ping.de>
5730 * backtrace.c (display_backtrace_file_and_line): Only use
5731 scm_basename when POSIX support is compiled in. Thanks to Chris
5734 2001-10-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
5736 * numbers.c (mem2uinteger): Return number read so far when coming
5737 across a hexdigit after having read a # or if not reading a hex
5738 value. This will enable the calling code to correctly handle
5739 forms like 1e2. (The background is, that the exponent markers d,
5740 e and f are also hexdigits.) Thanks to Mikael Djurfeldt for
5741 providing this patch.
5743 (mem2complex): Fix erroneous double-negation. Now, numbers like
5744 1-i will be read correctly.
5746 2001-10-12 Mikael Djurfeldt <mdj@linnaeus>
5748 * debug.c (scm_mem_to_proc): Fixed typo in previous change.
5750 * validate.h (SCM_VALIDATE_DOUBLE_DEF_COPY): New macro.
5752 2001-10-12 Dirk Herrmann <D.Herrmann@tu-bs.de>
5754 * print.c (scm_print_state_vtable, print_state_pool):
5755 Initialize. These variables are now registered as gc roots.
5757 (scm_current_pstate): Update documentation.
5759 (scm_current_pstate, scm_make_print_state, scm_free_print_state,
5760 scm_prin1, scm_init_print): print_state_pool is registered as a
5761 gc root and thus does not need to be protected by a surrounding
5764 (make_print_state): The car of print_state_pool no longer holds
5765 the scm_print_state_vtable.
5767 (scm_current_pstate, scm_make_print_state, print_circref,
5768 scm_iprin1, scm_prin1, scm_iprlist): Prefer !SCM_<foo> over
5771 (scm_prin1): When building lists, prefer scm_list_<n> over
5774 (scm_iprlist): Removed a redundant SCM_IMP test.
5776 (scm_simple_format): Use SCM_EQ_P to compare SCM values.
5778 2001-10-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
5780 * debug.c (scm_make_iloc): Prefer !SCM_<foo> over SCM_N<foo>.
5782 (scm_memcons, scm_mem_to_proc): When building lists, prefer
5783 scm_list_<n> over scm_cons[2]?.
5785 (scm_mem_to_proc): Prefer SCM_CONSP over SCM_NIMP.
5787 (scm_procedure_name): Use SCM_CADR instead of explicit form.
5789 (debugobj_print): Coerce scm_intprint arg 1 to long, not int.
5790 Thanks to Rob Browning for the patch (see log entry 2001-09-21) -
5791 for some reason his patch didn't make it into the cvs.
5793 2001-10-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
5795 * numbers.c (mem2decimal_from_point): Cleaned up the parsing a
5796 little bit - should even be somewhat more accurate now.
5798 2001-10-08 Rob Browning <rlb@defaultvalue.org>
5800 * gc.c: support ia64 register backing store.
5801 (SCM_MARK_BACKING_STORE): new macro.
5803 * continuations.h: support ia64 register backing store.
5804 (struct scm_t_contregs): add ia64 register backing store.
5806 * continuations.c: support ia64 register backing store.
5807 (continuation_mark): mark ia64 register backing store.
5808 (continuation_free): free ia64 register backing store.
5809 (scm_make_continuation): capture ia64 register backing store.
5810 (copy_stack_and_call): copy ia64 register backing store.
5812 2001-10-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
5814 * hashtab.c (scm_hash_fn_create_handle_x): The result of assoc_fn
5815 is known to be #f if no entry is found. Thus, use !SCM_FALSEP
5816 instead of SCM_NIMP to test for that case.
5818 * strings.h (SCM_SET_STRING_LENGTH): Cast the length to
5819 scm_t_bits instead of long.
5821 2001-10-06 Marius Vollmer <mvo@zagadka.ping.de>
5823 * tags.h (SCM_T_BITS_MAX, SCM_T_SIGNED_BITS_MAX,
5824 SCM_T_SIGNED_BITS_MIN): New.
5825 * numbers.h (SCM_MOST_POSITIVE_FIXNUM, SCM_MOST_NEGATIVE_FIXNUM):
5826 Use them to make these macros computable by the preprocessor.
5828 * num2integral.i.c (INTEGRAL2NUM): Let the preprocessor test
5829 whether the integral type fits in a fixnum, not the compiler.
5830 This removes a spurious compiler warning. Also, honor the
5831 NO_PREPRO_MAGIC flag to suppress any preprocessor tests. This is
5832 needed for `long long's.
5834 * numbers.c: Define NO_PREPRO_MAGOC when including
5835 num2integral.c.i for `long long' and `signed long long'.
5837 2001-10-06 Mikael Djurfeldt <mdj@linnaeus>
5839 These changes fixes a race condition in the Guile coop - pthread
5842 * coop.c (mother_awake_p): New variable.
5843 (coop_create): Set mother_awake_p before creating or signalling
5844 mother; wait until mother is going to sleep before returning.
5845 (mother): Reset mother_awake_p before going to sleep.
5847 2001-10-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
5849 * options.c (protected_objects, scm_init_options): The content of
5850 protected_objects is now protected from garbage collection using
5851 scm_gc_register_root instead of scm_permanent_object.
5853 (get_option_setting): New static function that computes an option
5854 setting as it was formerly done in the function scm_options.
5856 (get_documented_option_setting): New static function that
5857 returns option documentation as it was formerly done in the
5858 function scm_options. Note that documentation C strings are no
5859 longer precomputed into SCM objects. Instead, they are converted
5860 into SCM strings every time get_documented_option_setting is
5863 (change_option_setting): New static functions that modifies the
5864 option setting as it was formerly done in the function
5865 scm_options. The function is now exception safe, i. e. won't
5866 cause a memory leak when interrupted. Further, only non-immediate
5867 option values are added to the protection list.
5869 (scm_options): This function now has only the purpose to dispatch
5870 to to get_option_setting, get_documented_option_setting or
5871 change_option_setting, depending on the arguments given to
5874 (scm_init_opts): Don't convert documentation C strings into SCM
5875 strings. Further, don't protect any object values: They _must_
5876 be immediate values, otherwise there is no guarantee that they
5877 have not been collected before anyway.
5879 * options.[ch] (scm_t_option): Made type unsigned, name into a
5880 constant char* and val into a scm_t_bits type.
5882 (scm_options, scm_init_opts): The number of options is guaranteed
5883 to be larger or equal to zero. Thus, the type is changed to
5886 2001-10-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
5888 * num2integral.i.c (NUM2INTEGRAL): Eliminated some warnings about
5889 testing an unsigned value for being >= 0.
5891 2001-10-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
5893 * numbers.h: Removed old comment about using SCM_CAR to access
5896 (SCM_MOST_POSITIVE_FIXNUM, SCM_MOST_NEGATIVE_FIXNUM): Make sure
5897 the return value is signed. Thanks to Brian Crowder for the bug
5900 (SCM_SRS): Avoid unnecessary casting and don't unpack input
5901 values. With this patch, SCM_SRS can be safely used for other
5902 types than scm_t_signed_bits. However, it should still better be
5903 an internal macro and thus be renamed to SCM_I_SRS.
5905 (SCM_MAKINUM, SCM_INUM): Use proper casting.
5907 2001-10-03 Gary Houston <ghouston@arglist.com>
5909 * continuations.h, unif.h: in the descriptions of the bit patterns
5910 of the heap cells, make bit 0 the least significant.
5912 2001-09-25 Thien-Thi Nguyen <ttn@glug.org>
5914 * chars.h (SCM_MAKE_CHAR): Use `scm_t_bits' instead of `intptr_t'.
5915 Thanks to Golubev I. N.
5917 2001-09-25 Gary Houston <ghouston@arglist.com>
5919 * ports.c (scm_drain_input): extended the docstring. thanks to
5920 Alex Schroeder and Thien-Thi Nguyen.
5922 2001-09-23 Mikael Djurfeldt <mdj@linnaeus>
5924 * validate.h (SCM_NUM2FLOAT, SCM_NUM2DOUBLE,
5925 SCM_VALIDATE_FLOAT_COPY, SCM_VALIDATE_DOUBLE_COPY): New
5926 macros. (The NUM names might soon change.)
5928 * numbers.h: Added missing declarations.
5930 2001-09-22 Mikael Djurfeldt <mdj@linnaeus>
5932 * Makefile.am: Distribute num2float.i.c.
5934 * num2float.i.c: New file, multiply included by numbers.c, used
5935 to "templatize" the float <-> num conversion routines.
5937 * numbers.c: New functions: scm_num2float, scm_float2num,
5938 scm_num2double, scm_double2num.
5940 2001-09-21 Rob Browning <rlb@defaultvalue.org>
5942 * .cvsignore: really add version.h
5944 * strings.h (SCM_SET_STRING_LENGTH): coerce "l" to a long.
5945 Otherwise it fails on the alpha. However, we might rather choose
5946 this size conditionally.
5948 * numbers.c (scm_gcd): change "k" to a long from an int.
5949 Otherwise it fails on the alpha. However, we might rather choose
5950 this size conditionally.
5952 * error.c (scm_wta): coerce char* to intptr_t before int
5955 * debug.c (debugobj_print): coerce scm_intprint arg 1 to long, not
5958 * chars.h (SCM_MAKE_CHAR): coerce value to intptr_t.
5960 2001-09-20 Mikael Djurfeldt <mdj@linnaeus>
5962 * numbers.c (scm_integer_expt): Accept inexact integer in second
5963 argument. (Thanks to Bill Schottstaedt.)
5965 2001-09-20 Rob Browning <rlb@defaultvalue.org>
5967 * .cvsignore: add version.h
5969 * versiondat.h.in: removed (obsolete).
5971 * version.h.in: renamed from version.h.
5972 (SCM_GUILE_MAJOR_VERSION): new public macro.
5973 (SCM_GUILE_MINOR_VERSION): new public macro.
5974 (SCM_GUILE_MICRO_VERSION): new public macro.
5976 * version.h: renamed to version.h.in.
5979 (scm_major_version): support integer *_VERSION macros.
5980 (scm_minor_version): support integer *_VERSION macros.
5981 (scm_micro_version): support integer *_VERSION macros.
5982 (scm_version): support integer *_VERSION macros.
5984 2001-09-20 Mikael Djurfeldt <mdj@linnaeus>
5986 * error.c, error.h: Made error keys globally accessible.
5987 Applications might want to test for these or use them in a direct
5990 * num2integral.i.c (NUM2INTEGRAL): Report an error when these
5991 routines are passed an inexact. This change in behavior is
5992 motivated by concordance with R5RS: It is more common that a
5993 primitive doesn't want to accept an inexact for an exact.
5995 2001-09-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
5997 The following patch partially undoes my patch from 2001-06-30,
5998 where I added the function scm_gc_mark_cell_conservatively. The
5999 function is buggy, since it breaks guile during conservative
6000 marking if a pointer on the stack points directly into the list of
6001 free cells on the heap: With conservative cell marking this will
6002 cause the whole free list to be scanned and marked - boom!
6004 * gc.c (allocated_mark, MARK, heap_segment,
6005 scm_gc_mark_cell_conservatively, scm_init_storage), gc.h
6006 (scm_gc_mark_cell_conservatively): Remove function
6007 scm_gc_mark_cell_conservatively and update the corresponding
6008 comments and uses accordingly. Thanks to Christopher Cramer for
6009 the patch. (Minor corrections by me.)
6011 2001-09-15 Gary Houston <ghouston@arglist.com>
6013 * root.h (scm_root_state): removed the continuation_stack and
6014 continuation_stack_ptr members, which have no apparent purpose.
6015 (scm_continuation_stack, scm_continuation_stack_ptr): #defines
6018 * root.c (root_mark), init.c (restart_stack, start_stack), gc
6019 (scm_igc): remove all references to contination_stack and
6020 continuation_stack_ptr, avoiding allocation of a vector and
6021 useless processing during gc.
6023 2001-09-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
6025 * guardians.c (tconc_t, t_tconc): Renamed tconc_t to t_tconc.
6027 (TCONC_IN): Make sure that the cell word 0 is initialized last.
6029 (guardians_t, t_guardians): Renamed guardians_t to t_guardians.
6031 (GUARDIAN, GUARDIAN_DATA): Renamed GUARDIAN to GUARDIAN_DATA.
6033 (guardian_apply, scm_get_one_zombie, scm_make_guardian,
6034 mark_and_zombify): Prefer !SCM_<foo> over SCM_N<foo>.
6036 2001-09-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
6038 * guardians.c (mark_dependencies_in_tconc,
6039 whine_about_self_centered_zombies, scm_init_guardians): Register
6040 the static global variable `self_centered_zombies' via
6041 scm_gc_register_root, to make some cdr-ing unnecessary.
6043 2001-09-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
6045 * backtrace.c (display_backtrace_file,
6046 display_backtrace_file_and_line): Use SCM_EQ_P when comparing SCM
6047 values, use SCM_FALSEP when comparing SCM values against #f.
6048 Thanks to Rob Browning for the bug report.
6050 2001-09-12 Martin Baulig <martin@home-of-linux.org>
6052 * strings.[ch] (scm_str2string): New function.
6054 2001-09-06 Marius Vollmer <mvo@zagadka.ping.de>
6056 * gc.c (scm_done_free): Always subtract size from scm_mallocated
6057 when computing nm, even if it's negative.
6058 (scm_must_malloc): Abort on overflow of scm_mtrigger.
6059 (scm_must_realloc): Likewise.
6061 2001-09-01 Michael Livshin <mlivshin@bigfoot.com>
6063 * numbers.c (scm_sys_check_number_conversions): new function,
6064 defined if Guile is compiled in debugging mode. currently checks
6065 `scm_num2ulong', should check much much more.
6067 * num2integral.i.c (NUM2INTEGRAL): when converting a bignum to
6068 unsigned, ensure that it's positive. thanks to Martin Baulig!
6070 2001-08-31 Dirk Herrmann <D.Herrmann@tu-bs.de>
6072 * __scm.h: Added new section about compile time selectable
6075 (long_long, ulong_long, scm_sizet, SCM_WNA, SCM_OUTOFRANGE,
6076 SCM_NALLOC, SCM_HUP_SIGNAL, SCM_INT_SIGNAL, SCM_FPE_SIGNAL,
6077 SCM_BUS_SIGNAL, SCM_SEGV_SIGNAL, SCM_ALRM_SIGNAL, SCM_GC_SIGNAL,
6078 SCM_TICK_SIGNAL, SCM_SIG_ORD, SCM_ORD_SIG, SCM_NUM_SIGS):
6081 * deprecation.c (scm_include_deprecated_features): Simplified.
6083 * eval.c (EVALCAR, unmemocopy), eval.h (SCM_XEVALCAR): Use
6084 `SCM_IMP´ instead of `!SCM_CELLP´.
6086 * eval.c (unmemocopy): Eliminate redundant SCM_CELLP tests.
6087 Extract side-effecting operations from macros.
6089 (scm_init_eval): Don't initialize *top-level-lookup-closure*,
6090 scm_top_level_lookup_closure_var and scm_system_transformer.
6092 * gc.c (CELL_P): New local definition to replace SCM_CELLP.
6094 (heap_segment): Use CELL_P instead of SCM_CELLP.
6096 * init.c (start_stack): Don't initialize
6097 scm_top_level_lookup_closure_var and scm_system_transformer.
6099 * modules.c (scm_set_current_module): Don't access
6100 scm_top_level_lookup_closure_var and scm_system_transformer.
6102 (scm_sym2var): Don't call scm_variable_set_name_hint.
6104 (scm_post_boot_init_modules): Removed deprecated initializations.
6106 * print.c (scm_ipruk): Don't access cell contents of non cells.
6108 * strings.c (scm_string_set_x): All strings are writable.
6110 * strings.h (SCM_STRINGP): Use SCM_TYP7 to determine the string
6111 type. There is only one string type now.
6113 (SCM_STRING_COERCE_0TERMINATION_X): Deprecated.
6115 * tags.h: Remove comments about two different string types.
6117 (SCM_CELLP, SCM_NCELLP): Deprecated.
6119 * variable.c (make_variable): Remove code variant for vcells.
6121 * variable.h (SCM_VARIABLE_REF, SCM_VARIABLE_SET,
6122 SCM_VARIABLE_LOC): Remove code variant for vcells.
6124 * __scm.h, deprecation.[ch]: Renamed SCM_DEBUG_DEPRECATED to
6125 SCM_ENABLE_DEPRECATED with the logic reversed.
6127 * dynl.c (moddata, registered_mods), dynl.[ch]

6672 * .cvsignore: add stamp-h.in.
6674 2001-07-04 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
6676 * hooks.c (scm_make_hook, scm_add_hook_x),
6677 (scm_remove_hook_x, scm_reset_hook_x, scm_run_hook): Added return
6678 value info to the docstrings.

6688 * unif.c, script.c, rw.c, error.c: Include <io.h>, if it does
6691 * cpp_sig_symbols.in: Added SIGBREAK.
6693 2001-07-01 Marius Vollmer <mvo@zagadka.ping.de>
6695 * strports.c (scm_read_0str, scm_eval_0str): Call
6696 scm_c_read_string and scm_c_eval_string respectively, not
6697 themselves. Thanks to Dale P. Smith!
6699 2001-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
6701 * unif.c (scm_array_set_x): The variable args does not
6702 necessarily have to be a list. Further, got rid of a redundant
6705 2001-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
6707 * list.c (SCM_I_CONS): Make sure the cell type is initialized
6710 * gc.c (s_scm_map_free_list, scm_igc, scm_gc_sweep,
6711 init_heap_seg): Fixed signedness.
6713 (init_heap_seg): Replaced strange for-loop with a while loop.
6715 * weaks.h (WEAKSH, SCM_WEAKS_H): Rename <foo>H to SCM_<foo>_H.
6717 (SCM_WVECTP): Prefer !SCM_<pred> over SCM_N<pred>.
6719 The following patch adds conservative marking for the elements of
6720 free or allocated cells.
6722 * gc.c (allocated_mark, heap_segment): New static functions.
6724 (which_seg): Deleted, since the functionality is now provided by
6725 function heap_segment.
6727 (map_free_list): Use heap_segment instead of which_seg.
6729 (MARK): If cell debugging is disabled, mark free cells
6732 (scm_mark_locations, scm_cellp): Extracted the search for the
6733 heap segment of a SCM value into function heap_segment.
6735 (scm_init_storage): Allocated cells must be marked
6738 * gc.[ch] (scm_gc_mark_cell_conservatively): New function.
6740 The following patch changes the representation of weak vectors to
6741 double cells instead of using an extension of the vector's
6744 * gc.c (MARK): Use SCM_SET_WVECT_GC_CHAIN instead of assigning to
6745 the result of SCM_WVECT_GC_CHAIN.
6747 (scm_gc_sweep): Weak vectors don't have extra fields any more.
6749 * weaks.c (allocate_weak_vector): New static function. It does
6750 not patch any previously created vector object during the
6751 construction of a weak vector, and thus doesn't need to switch
6752 off interrupts during vector creation.
6754 (scm_make_weak_vector, scm_make_weak_key_hash_table,
6755 scm_make_weak_value_hash_table, scm_make_doubly_weak_hash_table):

6758 * weaks.h (SCM_WVECT_TYPE, SCM_SET_WVECT_TYPE,
6759 SCM_SET_WVECT_GC_CHAIN): New macros. The weak vector subtype is
6760 now stored in the double cell.
6762 (SCM_IS_WHVEC, SCM_IS_WHVEC_V, SCM_IS_WHVEC_B, SCM_IS_WHVEC_ANY):
6765 (SCM_WVECT_GC_CHAIN): The weak objects are now chained together
6766 using an entry of the double cell.

6795 SCM_LIST6, SCM_LIST7, SCM_LIST8, SCM_LIST9, scm_listify): Deprecated.
6796 (lots of files): Use the new functions.
6798 * goops.c (CALL_GF1, CALL_GF2, CALL_GF3, CALL_GF4): Use scm_call_N.
6800 * strings.c: #include "libguile/deprecation.h".
6802 2001-06-27 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
6804 * read.c (scm_lreadr): When reading a hash token, check for a
6805 user-defined hash procedure first, so that overriding the builtin
6806 hash characters is possible (this was needed for implementing
6807 SRFI-4's read synax `f32(...)').
6809 * num2integral.i.c: Use scm_t_signed_bits instead of scm_t_bits,
6810 because the latter is unsigned now and breaks comparisons like
6811 (n < (scm_t_signed_bits)MIN_VALUE).
6813 2001-06-26 Neil Jerram <neil@ossau.uklinux.net>
6815 * eval.h, eval.c (scm_call_4): New function.
6817 * eval.c (SCM_APPLY, SCM_CEVAL, ENTER_APPLY): Call trap handlers
6818 directly rather than dispatching to them via scm_ithrow and a lazy
6821 * eval.c (scm_evaluator_trap_table), eval.h (SCM_ENTER_FRAME_HDLR,
6822 SCM_APPLY_FRAME_HDLR, SCM_EXIT_FRAME_HDLR): Add three new options
6823 for trap handler procedures.
6825 * debug.h (SCM_RESET_DEBUG_MODE): Add checks for trap handler
6826 procedures not being #f.
6828 2001-06-27 Michael Livshin <mlivshin@bigfoot.com>
6830 * Makefile.am (c-tokenize.c): add rule to generate it.
6831 (EXTRA_DIST): add c-tokenize.lex, so it gets distributed.
6833 filter-doc-snarfage.c: remove.
6835 2001-06-26 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
6837 * ports.c (scm_output_port_p): Use result of SCM_COERCE_OUTPORT.
6839 The following set of changes makes compiling Guile under various
6840 Windows compilers easier. Compilation under GNU systems should
6841 not be affected at all.
6843 Thanks to Stefan Jahn for all necessary information, patches and
6846 * posix.c: Conditialize getpwent, getgrent, kill, getppid, getuid,

6854 Windows and conditionalize some signal names.
6856 * socket.c (scm_getsockopt): Added missing comma.
6857 Include socket library header under Windows.

6869 * guile.c (inner_main): Under Windows, initialize socket library
6870 and initialize gdb_interface data structures.
6872 * gdb_interface.h: Under Windows, gdb_interface cannot be
6873 initialized statically. Initialize at runtime instead.
6875 * fports.c (write_all): ssize_t -> size_t.
6876 (fport_print): Conditionalize call to ttyname().
6877 (getflags): New function, compiled only under Windows.
6879 * filesys.c: Conditionalize inclusion of <pwd.h>. Conditionalize
6880 primitives chown, link, fcntl.
6881 (scm_basename, scm_dirname): Under Windows, handle \ as well as /
6884 * backtrace.c: Include <io.h> under Windows.

6920 2001-06-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
6922 * filesys.c (scm_close), ports.c (scm_close_port,
6923 scm_port_closed_p), strop.c (scm_string_null_p): Use SCM_BOOL
6924 instead of SCM_NEGATE_BOOL.

6960 * strings.h (STRINGSH, SCM_STRINGS_H): Rename <foo>H to
6963 * validate.h (SCM_VALIDATE_SUBSTRING_SPEC_COPY): Eliminate
6964 warning about comparing signed and unsigned values. This fix is
6965 not optimal, since it won't work reliably if sizeof (c_start) >
6966 sizeof (size_t) or sizeof (c_end) > sizeof (size_t). A better
6967 solution is to define this macro as an inline function, thus
6968 allowing to specifiy the types of c_start and c_end.
6970 2001-06-25 Dirk Herrmann <D.Herrmann@tu-bs.de>

6994 (scm_last_stack_frame): Remove bogus `;´.
6996 * stacks.h (SCM_FRAMEP): Fix type check.
6998 2001-06-25 Michael Livshin <mlivshin@bigfoot.com>
7000 * Makefile.am (MAINTAINERCLEANFILES): be sure to remove
7001 c-tokenize.c when doing maintainer-clean.
7003 * snarf.h (SCM_SNARF_DOCS): change the "grammar" slightly.
7005 * guile-snarf-docs.in, guile-snarf-docs-texi.in: rewrite &

7024 they aren't defined already.
7026 2001-06-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
7028 * backtrace.c (display_backtrace_body): Use SCM_VALIDATE_STACK
7029 and SCM_VALIDATE_OPOUTPORT instead of SCM_ASSERT. Fix signedness
7032 * backtrace.c (display_expression, scm_set_print_params_x,
7033 display_application, display_frame, scm_backtrace), numbers.c
7034 (scm_istring2number), objects.c (scm_class_of,
7035 scm_mcache_lookup_cmethod, scm_mcache_compute_cmethod): Prefer
7036 explicit type check over SCM_N?IMP, !SCM_<pred> over SCM_N<pred>.

7062 2001-06-20 Gary Houston <ghouston@arglist.com>
7064 * deprecation.c, extensions.c, rw.c: include string.h.
7066 2001-06-19 Gary Houston <ghouston@arglist.com>
7068 * filter-doc-snarfage.c (process): added ungetc in
7069 MULTILINE_COOKIE case since otherwise it fails when there's no
7070 space between the '(' and the quote of the following string
7073 2001-06-14 Marius Vollmer <mvo@zagadka.ping.de>
7075 Throughout: replace "scm_*_t" with "scm_t_*", except "scm_lisp_t".
7077 2001-06-14 Marius Vollmer <mvo@zagadka.ping.de>
7079 * unif.h (SCM_ARRAY_NDIM): Shift then cast so that no sign

7509 scm_array_dim->scm_array_dim_t to enable build with
7510 --disable-deprecated.
7512 2001-05-24 Michael Livshin <mlivshin@bigfoot.com>
7514 The purpose of this set of changes is to regularize Guile's usage
7515 of ANSI C integral types, with the following ideas in mind:
7517 - SCM does not nesessarily have to be long.
7518 - long is not nesessarily enough to store pointers.
7519 - long is not nesessarily the same size as int.
7521 The changes are incomplete and possibly buggy. Please test on

8687 2001-03-31 Michael Livshin <mlivshin@bigfoot.com>
8689 * backtrace.c (display_backtrace_body): since the `print_state'
8690 variable is not used (instead its data field is used directly as
8691 `pstate'), protect it from the hungry compiler optimizations.
8692 thanks to Bill Schottstaedt for the report.
8694 2001-03-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
8696 * gc.[ch] (scm_tc16_allocated): New type tag for allocated cells.
8697 It is only defined and used if guile is compiled with
8698 SCM_DEBUG_CELL_ACCESSES set to true. It's purpose is, to never
8699 let cells with a free_cell type tag be visible outside of the
8700 garbage collector when in debug mode.
8702 * gc.c (scm_debug_cell_accesses_p): Set to true as default.
8704 (scm_assert_cell_valid): Use a local static variable to avoid
8707 (MARK): Only check for rogue cell pointers in debug mode. Use
8708 scm_cellp for this purpose and place all checks for rogue pointers
8709 into that function. Further, since due to conservative scanning
8710 we may encounter free cells during marking, don't use the standard
8711 cell type accessor macro to determine the cell type.
8713 (scm_cellp): Check if the cell pointer actually points into a
8716 (scm_init_gc): Initalize scm_tc16_allocated.
8718 * gc.h (GCH): Renamed to SCM_GC_H.
8720 (SCM_VALIDATE_CELL): Enclose the expression in brackets. This
8721 might be unnecessary, but I feel better this way :-)
8723 (SCM_GC_CELL_TYPE): New macro.
8725 (SCM_SETAND_CDR, SCM_SETOR_CDR): Deprecated. These are not used
8726 in guile, and it is unlikely that they will be applied to real
8729 (SCM_SET_FREE_CELL_TYPE): Removed. It was not used.
8731 (SCM_GC_SET_ALLOCATED): New macro. Only non-empty if guile is
8732 compiled with SCM_DEBUG_CELL_ACCESSES set to true.
8734 (SCM_NEWCELL, SCM_NEWCELL2): Use of SCM_GC_SET_ALLOCATED will
8735 make sure that in debug mode no free cell will ever be visible
8736 outside of the garbage collector.
8738 2001-03-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
8740 * async.c (scm_asyncs_pending): Don't use != to compare SCM

8747 Remove suspicious use of SCM_SLOPPY_CONSP.
8749 * eq.c (scm_equal_p), tags.h (SCM_ECONSP): Use SCM_CONSP instead
8750 of SCM_SLOPPY_CONSP. A sane compiler should be able to perform
8751 the corresponding optimization.
8753 * eval.c (iqq): Use proper type check.
8755 (scm_m_expand_body): Remove redundant type checks.
8757 (promise_print): Don't access promise cells as pairs.
8759 * eval.c (EVALCAR, iqq, scm_m_expand_body, scm_eval_args,
8760 scm_deval_args SCM_CEVAL), guardians.c (scm_guard), hashtab.c
8761 (scm_internal_hash_fold), print.c (scm_iprlist): Use !SCM_CELLP
8762 for SCM_NCELLP, !SCM_CONSP for SCM_NCONSP, !SCM_IMP for SCM_NIMP,
8763 !SCM_FALSEP for SCM_NFALSEP, !SCM_NULLP for SCM_NNULLP
8765 * eval.c (scm_m_define, scm_macroexp, SCM_CEVAL), print.c
8766 (scm_iprin1): Use new macro predicate and accessors.
8768 * eval.h (scm_tc16_macro): Removed declaration. It is declared
8771 * eval.h (EVALH), macros.h (MACROSH), ports.h (PORTSH), procs.h
8772 (PROCSH), tags.h (TAGSH), variable.h (VARIABLEH): Renamed to
8773 SCM_EVAL_H, SCM_MACROS_H, SCM_PORTS_H, SCM_PROCS_H, SCM_TAGS_H and
8774 SCM_VARIABLE_H. Even the macros that are used to inhibit
8775 including a header file twice should be in the SCM_ namespace.
8777 * fluids.c (scm_swap_fluids, scm_swap_fluids_reverse),
8778 properties.c (scm_primitive_property_ref,
8779 scm_primitive_property_del_x): Prefer stronger predicates like
8780 SCM_NULLP or SCM_FALSEP over SCM_IMP.
8782 * gc.c (MARK): Use proper macros to access procedure-with-setter
8783 cell elements and closure cell elements.
8785 (gc_sweep_freelist_finish, scm_gc_sweep, init_heap_seg): Don't
8786 access free cells as pairs.
8788 (scm_unprotect_object): scm_hashq_get_handle returns #f if
8789 no hashtab entry is found.
8791 * gc.c (scm_gc_sweep), ports.c (scm_close_port): Use new macro
8792 SCM_CLR_PORT_OPEN_FLAG.
8794 * guardians.c (TCONC_IN), print.c (scm_free_print_state): Don't
8795 use SCM_SET_C[AD]R for uninitialized cells.
8797 * hashtab.c (scm_hash_fn_get_handle): Use SCM_VALIDATE_VECTOR.
8798 If the hashtable has no slots, return #f instead of '(). This
8799 unifies the return value with most assoc-functions.
8801 (scm_hash_fn_ref): Use proper type check.
8803 (scm_hashq_get_handle, scm_hashv_get_handle, scm_hash_get_handle):
8804 Removed references to non-existing functions from documentation.
8806 * keywords.c (scm_keyword_dash_symbol): Use proper macros to
8807 access keyword cell elements.
8809 * macros.h (SCM_MACROP, SCM_MACRO_TYPE, SCM_MACRO_CODE): New
8812 * ports.h (SCM_CLR_PORT_OPEN_FLAG): New macro.

8827 * variable.c (variable_print, variable_equalp, scm_variable_ref,
8828 scm_variable_set_x): Use proper macros to access variable cell
8831 (scm_variable_bound_p): Don't use SCM_NEGATE_BOOL.
8833 * variable.h (SCM_VARVCELL): Don't access variable cells as
8836 * vectors.c (scm_vector), weaks.c (scm_weak_vector): Simplified,
8837 added FIXME comment, removed register specifier.
8839 2001-03-29 Keisuke Nishida <kxn30@po.cwru.edu>
8841 * goops.c, goops.h (scm_init_oop_goops_goopscore_module): Deprecated.
8842 * init.c (scm_init_guile_1): Don't init goopscore module.
8844 2001-03-27 Marius Vollmer <mvo@zagadka.ping.de>
8846 * eval.c (SCM_APPLY): Check that arg1 is bound for scm_tc7_cxr.

8871 New delcarations to support above change.
8873 * eval.c (scm_primitive_eval_x, scm_primitive_eval): Fix syntax
8874 errors with last change.
8876 2001-03-25 Marius Vollmer <mvo@zagadka.ping.de>

9043 2001-03-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
9045 * gh.h/gh_data.c (gh_ints2scm): Changed the signature to use a
9046 const int* to reflect that the input array of integers remains
9047 unchanged. Thanks to Brett Viren for the hint.
9049 2001-03-14 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>

9074 * goops.c (scm_m_atslot_ref, scm_m_atslot_set_x,
9075 scm_m_atdispatch): Provide definitions for FUNC_NAME. Don't use
9076 SCM_ASSYNT to check for correct argument types. Either use some
9077 SCM_VALIDATE_* macro or an explicit test.
9079 (scm_make_foreign_object): Don't use SCM_ASSERT to check for
9082 * macros.h (SCM_ASSYNT): On assertion failure, issue a misc-error
9083 instead of calling scm_wta.
9085 2001-03-12 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
9087 * load.c (scm_primitive_load, scm_primitive_load_path),

9106 * _scm.h: Removed #include <errno.h>.
9108 * error.c, net_db.c, putenv.c, stime.c: Removed declaration of
9109 errno variable (can be a macro on some systems, for example when
9110 using linux libc with threads).
9112 * error.c, filesys.c, gc.c, ioext.c, iselect.c, net_db.c, ports.c,

9170 2001-03-08 Neil Jerram <neil@ossau.uklinux.net>
9172 * ports.c (scm_port_column): Docstring fixes: (i) port-line arg is
9173 not optional (ii) "recommend" spelling correction.
9175 2001-03-08 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
9177 * ramap.c (racp): Removed optimization which caused array copying
9178 to fail if the two arrays shared storage. Re-inserted the IVDEP
9179 macros removed in the change of 2000-03-09. (Don't really have a
9180 complete grasp of what they are for, but they seem to be necessary
9181 on Crays. This needs testing!) Thanks to Miroslav Silovic.
9183 * hash.c (scm_string_hash): Don't downcase characters.
9185 2001-03-07 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
9187 * symbols.c (scm_symbols_prehistory): Changed symbol hash table

9200 (*.doc): Add dependency on guile-snarf.awk.in.
9202 * guile-snarf.awk.in: Neglect spaces at the end of
9203 SCM_SNARF_DOCSTRING_END. Skip lines "# NN ..." in the
9204 middle of docstrings. (To avoid the problem with gcc-2.96.)
9206 2001-03-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
9208 * coop-threads.c (scm_call_with_new_thread), load.c

9210 (scm_c_default_rstate), struct.c (scm_make_struct_layout,
9211 scm_struct_ref, scm_struct_set_x): Don't use SCM_ASSERT to
9212 (potentially) issue a scm-misc-error or wrong-num-args error
9215 * load.c (scm_search_path): Use SCM_ASSERT_TYPE to give details
9216 about the expected type with the wrong-type-arg error message.
9218 * smob.c (scm_make_smob): Abort on misuse of smob - it indicates
9219 a C level bug that can't be fixed from scheme anyway.
9221 2001-03-05 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
9223 * eval.c (scm_m_letstar): Removed check for duplicate bindings.
9224 Duplicate bindings are OK in a let* since a let* is semantically
9225 equivalent to a nested set of let:s.
9227 2001-03-05 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
9229 * print.c (scm_print_options): Fixed texinfo in docstring.
9231 * net_db.c (scm_getserv, scm_getproto, scm_getnet): Return #f if
9232 the underlying functions getservent, getprotoent or getnetent
9233 return NULL instead of signalling an error.
9235 2001-03-04 Gary Houston <ghouston@arglist.com>
9237 * socket.c (scm_fill_sockaddr): don't allow buffer overflows when
9238 taking an unexpectedly large filename for an AF_UNIX socket from
9239 bind/connect/sendto (thanks to Martin Grabmueller).
9241 * socket.c (scm_sock_fd_to_port, SCM_SOCK_FD_TO_PORT): removed the
9242 former and adjusted the latter.
9243 (scm_socket, scm_socketpair): cosmetic changes.
9244 (scm_getsockopt, scm_setsockopt): declare optlen as int, not
9245 size_t as socklen_t substitute. don't restrict args/return values
9246 to INUM: allow full range of int or size_t.
9247 (scm_fill_sockaddr): check arguments before allocating memory, to
9248 avoid leakage. use malloc, not scm_must_malloc.
9249 (scm_connect, scm_bind, scm_sendto): use int, not size_t as socklen_t
9250 substitute. free the sockaddr structure before throwing an error.
9251 (scm_init_add_buffer): procedure removed, together with its static
9252 buffer scm_addr_buffer, which wouldn't be thread safe. instead,
9253 define a macro MAX_ADDR_SIZE and declare the buffer where needed.
9254 (scm_accept, scm_getpeername, scm_getsockname, scm_recvfrom,
9255 scm_sendto): use a local buffer instead of scm_addr_buffer.
9256 adjust for new SCM_SOCK_FD_TO_PORT. use int for address size,
9258 (scm_recvfrom): set addr->sa_family to AF_UNSPEC before the recvfrom
9259 call to detect whether recvfrom could be bothered to set the address.
9260 (scm_init_socket): don't call scm_init_addr_buffer.
9262 2001-03-04 Dirk Herrmann <D.Herrmann@tu-bs.de>

9273 scm_array_to_list, scm_array_prototype), validate.h
9274 (SCM_VALIDATE_NUMBER_COPY): Don't call function scm_wta, call
9275 scm_misc_error or scm_wrong_type_arg instead.
9277 * validate.h (SCM_WTA, RETURN_SCM_WTA): Deprecated.
9279 2001-03-04 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
9281 * goops.c, goops.h (scm_sys_pre_expand_closure_x): Removed.

9292 scm_lreadparen, scm_lreadrecparen), script.c (script_get_octal,
9293 script_get_backslash, script_read_arg), unif.c (scm_cvref): Don't

9310 * eval.c (scm_s_duplicate_formals): New error message string.
9311 (scm_c_improper_memq): New function.
9312 (scm_m_lambda): Check for duplicate arguments.
9313 (scm_ceval, scm_deval): When executing a body: only cons a new
9314 toplevel environment frame when it is different from the
9315 existing one; use EVALCAR instead of SIDEVAL so that we can properly
9316 check for empty combinations; use SCM_EVALIM2 for the same reason
9317 in the non-toplevel loop.
9318 (nontoplevel_cdrxnoap, nontoplevel_cdrxbegin, nontoplevel_begin):
9319 New labels with the meaning of their non-"nontoplevel" partners,
9320 but they are used when it is known that the body is not evaluated at
9322 (scm_apply, scm_dapply): use SCM_EVALIM2 to get proper error
9323 reporting for empty combinations.
9325 2001-03-02 Keisuke Nishida <kxn30@po.cwru.edu>
9327 * Remove dump facilities.

9390 * numbers.c (scm_two_doubles, scm_sys_expt, scm_sys_atan2,
9391 scm_make_polar): Rename arguments `z1' and `z2' to `x' and `y',
9392 since use of `z' suggests that the arguments may be complex.
9394 * goops.c (scm_make), numbers.c (scm_sys_expt): Fix docstring
9397 2001-02-23 Neil Jerram <neil@ossau.uklinux.net>

9412 (scm_init_goops): Make scm_module_goops and
9413 scm_goops_lookup_closure permanent objects.
9415 * eval.c (scm_ceval, scm_deval): When evaluating expressions on
9416 top level, create a fresh top-level environment for each
9417 expression instead of mutating the exisint frame. This is
9418 important when that frame is closed over.
9420 * numbers.c (s_scm_logior) [SCM_DIGSTOOBIG]: Also use
9421 SCM_DIGSPERLONG instead of DIGSPERLONG.
9423 2001-02-21 Marius Vollmer <mvo@zagadka.ping.de>
9425 * eval.c (scm_ceval, scm_deval): Check for wrong number of args
9426 before applying arrow procedure in `cond' and before applying
9427 receiver procedure in call-with-current-continuation.
9428 (scm_i_eval): Do not invoke scm_copy_tree in argument in SCM_XEVAL
9429 macro. The argument is expanded more than one time.
9431 * numbers.c (scm_logior) [SCM_DIGSTOOBIG]: Correctly use
9432 SCM_BIGDIG instead of BIGDIG. Thanks to Steven G. Johnson!

9556 2001-02-13 Marius Vollmer <marius.vollmer@uni-dortmund.de>
9558 * gc_os_dep.c: Do not include <linux/version.h>. It makes no
9559 sense to compile for a specific kernel version. Do not include

9563 2001-02-13 Marius Vollmer <mvo@zagadka.ping.de>
9565 * eval.c (scm_ceval, scm_deval): use `SIDEVAL' instead of

9584 names to better reflect their meaning.
9586 * eval.c (scm_ceval, scm_deval): Recognize when `begin' is being

9616 scm_selected_module to scm_current_module to synchronize Scheme
9618 (scm_select_module, scm_set_current_module): Likewise. Changed
9621 * ports.c (scm_port_for_each): Make a snapshot of the port table
9622 before iterating over it. The table might change while the user
9623 code is running. With the snapshot, the user can depend on the
9624 fact that each port that existed at the start of the iteration is
9625 encountered exactly once. (ice-9 popen) depends on this.
9627 2001-02-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
9629 * strings.h (SCM_STRING_MAX_LENGTH): New macro.
9631 * strings.c (scm_makstr, scm_take_str, scm_make_string): Added
9632 range checking for the size parameter. Thanks to Martin
9633 Grabmueller for the hint.

9645 checking of the size parameter for type correctness and valid
9646 range. Thanks to Rob Browning for reporting the problem. Instead
9647 of deferring interrupts, scm_remember_upto_here_1 is used.
9649 2001-02-05 Keisuke Nishida <kxn30@po.cwru.edu>
9651 * dump.c (scm_store_cell_object, scm_restore_cell_object): Removed.

9678 the deprecated SCM_DOUBLE_CELLP.
9680 * tags.h (SCM_DOUBLE_CELLP): deprecated.
9682 2001-02-02 Keisuke Nishida <kxn30@po.cwru.edu>

9852 checking. Thanks to Neil Jerram for the bug report.
9854 * backtrace.[ch] (scm_i_display_error): New function.
9856 * backtrace.c (scm_display_error): Added parameter check and
9857 extracted the core functionality into function
9858 scm_i_display_error.
9860 * throw.c (handler_message): Call scm_i_display_error to display
9863 2001-01-23 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
9865 * eval.c (SCM_APPLY): Added # args check for application of
9866 procedures with arity 3. (Thanks to Anders Holst.)

9870 * filesys.h (SCM_DIR_FLAG_OPEN, SCM_DIR_OPEN_P): Added.
9872 (SCM_OPDIRP): Deprecated.
9874 * filesys.c (scm_opendir): Use SCM_DIR_FLAG_OPEN instead of
9877 (scm_readdir, scm_rewinddir): Don't use SCM_VALIDATE_OPDIR.
9878 Instead, give an explicit error message in case the directory is
9881 (scm_closedir, scm_dir_print): Rewritten to use SCM_DIR_OPEN_P
9882 instead of SCM_OPENP and SCM_CLOSEDP.
9884 * validate.h (SCM_VALIDATE_OPDIR): Deprecated.
9886 2001-01-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
9888 * eval.c (inner_eval, scm_eval): Move all real functionality into
9889 inner_eval. Avoid to copy the expression twice by inlining some
9890 code from scm_i_eval.
9892 2001-01-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
9894 * eval.c (scm_m_case): The 'else' clause of a 'case' statement

9922 2001-01-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
9924 * __scm.h (SCM_FIXNUM_BIT): Added. The name is chosen in analogy
9925 to the names in limits.h.
9927 * numbers.c (abs_most_negative_fixnum): Added.
9929 (scm_quotient, scm_remainder): Fixed the fixnum-min / (abs
9930 fixnum-min) special case.

9934 (scm_bit_extract): Fix for fixnum paramters.
9935 Thanks to Rob Browning for the bug report.

9951 from Matthias Köppe:
9953 * objects.h (SCM_SET_ENTITY_SETTER): new macro. SCM_ENTITY_SETTER
9954 casts its result, so doesn't yield an lvalue per ANSI C.
9956 * goops.c (s_scm_sys_set_object_setter_x): use
9957 SCM_SET_ENTITY_SETTER.
9958 (clear_method_cache): use SCM_SET_ENTITY_PROCEDURE.
9960 * gc.h (SCM_GC_SET_CARD_BVEC): new macro. SCM_GC_CARD_BVEC casts
9961 its result, so doesn't yield an lvalue per ANSI C.
9962 (SCM_GC_SET_CARD_FLAGS): ditto for SCM_GC_GET_CARD_FLAGS.
9963 (SCM_GC_CLR_CARD_FLAGS): redefined in terms of
9964 SCM_GC_SET_CARD_FLAGS.
9965 (SCM_GC_SET_CARD_FLAG, SCM_GC_CLR_CARD_FLAGS): ditto.
9967 * gc.c (INIT_CARD): use the explicit setter macro to set the bvec.
9969 2001-01-08 Gary Houston <ghouston@arglist.com>
9971 * validate.h (SCM_VALIDATE_SUBSTRING_SPEC_COPY): new macro.
9972 * ioext.c (scm_read_string_x_partial, scm_read_delimited_x),
9973 socket.c (scm_recvfrom): use the new macro, plus minor docstring
9975 * ioext.c (scm_read_string_x_partial): don't crash if -1 is supplied
9976 for fdes. if current input port is used, check that it's a file
9979 2001-01-06 Gary Houston <ghouston@arglist.com>
9981 * ioext.c (scm_read_string_x_partial): new procedure, implements
9982 read-string!/partial.
9983 * ports.c (scm_take_from_input_buffers): new procedure used by
9984 scm_read_string_x_partial.
9985 (scm_drain_input): use scm_take_from_input_buffers.
9987 2001-01-06 Marius Vollmer <mvo@zagadka.ping.de>
9989 * validate.h (SCM_VALIDATE_NUMBER): New.
9991 2001-01-03 Michael Livshin <mlivshin@bigfoot.com>
9993 * guardians.c (F_GREEDY, F_LISTED, F_DESTROYED, GREEDY_P,
9994 SET_GREEDY, LISTED_P, SET_LISTED, CLR_LISTED, DESTROYED_P,
9995 SET_DESTROYED): new defines/macros.
9996 (GUARDIAN_LIVE, GUARDIAN_ZOMBIES, GUARDIAN_NEXT): deleted.
9997 (add_to_live_list): takes a `guardian_t *' now, not SCM.
9998 (guardian_print): print more info.
9999 (guardian_apply): check if the guardian is destroyed, and throw an
10000 error if so. take one more optional argument `throw_p'.
10001 (scm_guard): depending on the value of `throw_p', return a boolean
10003 (scm_get_one_zombie): remove redundant property test.
10004 (guardian_t): represent the various (currently 3, I hope nothing
10005 more gets added) boolean fields as bit flags.
10006 (scm_guardian_destroyed_p, scm_guardian_greedy_p): new predicates.
10007 (scm_destroy_guardian_x): new procedure.
10009 * guardians.h: added prototypes for `scm_guardian_greedy_p' and
10010 `scm_guardian_destroyed_p'. changed prototype for `scm_guard'.
10012 2001-01-01 Gary Houston <ghouston@arglist.com>
10014 * fports.c (fport_write): bugfix: handle short writes for
10015 unbuffered ports too. optimize the buffered case by minimizing
10016 the number of write/flush calls.
10017 (write_all): new helper procedure.
