1 2004-06-15 Rob Browning <rlb@defaultvalue.org>
3 * script.c (scm_shell_usage): minor phrasing change.
5 * gc_os_dep.c: update ifdefery for macosx.
6 (scm_get_stack_base): separate result initialization from
7 declaration to slience warnings with macosx and hp-ux using gcc
8 3.3. Thanks to Andreas Vögele.
10 2004-06-13 Han-Wen Nienhuys <hanwen@xs4all.nl>
12 * eval.c (unmemoize_exprs): use SCM_CONSP for the loop condition.
14 2004-06-06 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
16 * list.[ch] (scm_i_finite_list_copy): New internal function to
17 copy lists that are known to be finite (though not necessarily
20 * debug.c (scm_procedure_source): Don't have scm_unmemocopy treat
21 a closure's argument list like an expression of a body.
23 * eval.c (unmemoize_expression, unmemoize_exprs, unmemoize_and,
24 unmemoize_begin, unmemoize_case, unmemoize_cond, unmemoize_delay,
25 unmemoize_do, unmemoize_if, unmemoize_lambda, unmemoize_let,
26 unmemoize_letrec, unmemoize_letstar, unmemoize_or,
27 unmemoize_set_x, unmemoize_apply, unmemoize_atcall_cc,
28 unmemoize_at_call_with_values, unmemoize_future, sym_atslot_ref,
29 unmemoize_atslot_ref, sym_atslot_set_x, unmemoize_atslot_set_x,
30 unmemoize_builtin_macro): New static functions and symbols.
32 (scm_unmemocopy): Rewritten in terms of the above. scm_unmemocopy
33 now has a slightly different meaning: The memoized form that is
34 receives as its argument is now interpreted as a sequence of
35 expressions from a body.
37 (unmemocar, scm_unmemocar): Since the whole functionality of
38 unmemocar and scm_unmemocar is not needed any more, scm_unmemocar
39 has its old content back and is deprecated, while unmemocar has
44 (CEVAL): For unmemoizing a single expression, call
45 unmemoize_expression instead of scm_unmemocopy, which now expects
46 a sequence of body expressions. Eliminated unnecessary empty
47 environment frame when executing let* forms. Eliminated
48 unmemoization step from evaluator.
50 2004-06-02 Marius Vollmer <marius.vollmer@uni-dortmund.de>
52 * eval.c (scm_macroexp, macroexp): Renamed scm_macroexp to
53 macroexp and made static. Added new version of scm_macroexp that
54 emits a deprecation warning and then calls macroexp.
55 (scm_m_undefine): Issue deprecation warning.
57 2004-05-30 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
59 * eval.c (lookup_global_symbol, literal_p, try_macro_lookup):
60 Modified to make set! work on symbols that represent syntactic
63 2004-05-26 Han-Wen Nienhuys <hanwen@xs4all.nl>
65 * gc.h (SCM_CELL_OBJECT_LOC): use SCM_GC_CELL_OBJECT to prevent
66 compound expression as lvalue errors.
68 2004-05-24 Marius Vollmer <mvo@zagadka.de>
70 * dynwind.c (winder_mark): Use SCM_PACK to correctly convert the
73 2004-05-24 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
75 * goops.c (compute_getters_n_setters, create_standard_classes,
76 scm_add_slot): Compute closures by calling scm_i_eval_x on a
77 lambda expression rather than creating them with scm_closure.
79 2004-05-22 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
81 * eval.c (s_macro_keyword, scm_m_set_x): Remove checking for
82 misplaced syntactic keywords. This will not work unless guile's
83 defmacro feature is deprecated.
85 (scm_m_case): Fixed a bug that caused the list of labels to grow
88 2004-05-19 Kevin Ryde <user42@zip.com.au>
90 * numbers.c (scm_round_number): For inum and big, just return x. For
91 real, use scm_round for 2^54-1 etc problems covered there.
93 * numbers.c (trunc): Remove #define to scm_truncate when the C library
94 doesn't provide trunc. This was for when `truncate' was done as a
95 scm_tc7_dsubr, no longer required.
97 * threads.c (scm_threads_mark_stacks) [SCM_STACK_GROWS_UP]: Correction
98 to stack marking call, two parameters and no cast on t->base.
100 2004-05-18 Marius Vollmer <mvo@zagadka.de>
102 * hashtab.c (rehash_after_gc): Bug fix: properly link the
103 processed hashtables back into the weak_hashtables list. Thanks
104 to Bill Schottstaedt!
106 2004-05-16 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
108 * eval.c (unmemoize_quote): New static function.
110 (scm_m_quote, scm_m_atslot_ref, SCM_CEVAL): Changed the byte code
111 representation of 'quote' and '@slot-ref' to an improper list.
112 This reduces execution time, the number of cells used to hold the
113 memoized code, and thus also reduces garbage collection time.
115 (scm_unmemocopy): Use unmemoize_quote for quote expressions.
117 (SCM_CEVAL): Changed macro handling to also work with macros that
118 return improper lists. Added an assertion, that the code returned
119 by a macro transformer will not lead to cycles in the memoized
122 2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
124 No functional change, just rearrangements of functions within the
127 * eval.c (scm_ilookup, scm_unbound_variable_key,
128 error_unbound_variable, scm_lookupcar1, scm_lookupcar): Moved to
129 the definitions used for execution, since that's where they will
132 2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
134 * numbers.h (SCM_SLOPPY_FRACTIONP): Removed. It was not used
135 throughout guile, has not been part of an official release yet,
136 and the concept of sloppy predicates has never been a good idea.
138 (SCM_FRACTION_NUMERATOR, SCM_FRACTION_DENOMINATOR,
139 SCM_FRACTION_SET_NUMERATOR, SCM_FRACTION_SET_DENOMINATOR):
142 2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
144 * throw.c (SETJBJMPBUF, SCM_SETJBDFRAME): Add cast to scm_t_bits
145 to make explicit what happens.
147 2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
149 * dynl.c (SET_DYNL_HANDLE): Add cast to scm_t_bits to make
150 explicit what happens.
152 * guardians.c (TCONC_IN): Use SCM_SET_CELL_OBJECT_x rather than
153 SCM_SET_CELL_WORD_x when writing scheme objets to cell elements.
155 2004-05-11 Marius Vollmer <mvo@zagadka.de>
157 * scmsigs.c (scm_sigaction_for_thread): Validate that the handler
158 is indeed a procedure when it isn't a number.
160 2004-05-10 Marius Vollmer <mvo@zagadka.de>
162 Convert floating point numbers into strings with an arbitrary
163 radix. Thanks to Richard Todd!
165 * numbers.c (FLOBUFLEN): Increase so that radix 2 strings will
168 (scm_dblprec, fx_per_radix, init_dblprec, init_fx_radix,
169 number_chars): New, to support variable radices.
170 (idbl2str): Use above instead of the old base-10 only tables.
171 (iflo2str): Pass on new RADIX argument to idbl2str.
172 (scm_number_to_string): Pass radix to iflo2str.
173 (scm_print_real, scm_print_complex): Explicitly pass radix 10 to
175 (scm_init_numbers): Call init_dblprec and init_fx_radix for all
178 2004-05-10 Kevin Ryde <user42@zip.com.au>
180 * numbers.c (scm_logbit_p): Correction to test above the end of an
181 inum. Reported by Jan Konecny.
183 2004-05-06 Marius Vollmer <marius.vollmer@uni-dortmund.de>
185 * gc.h (scm_t_cell): Fields are now of type SCM instead of
186 scm_t_bits. Updated all users.
187 (SCM_GC_CARD_SIZE_MASK): Use SCM_GC_SIZEOF_CARD instead of
188 duplicating the code.
189 (SCM_CELL_OBJECT_LOC): New.
190 (SCM_CARLOC, SCM_CDRLOC): Use it instead of SCM_CELL_WORD_LOC.
191 (SCM_CELL_WORD_LOC): Moved to "deprecated.h".
193 * smob.h (SCM_SMOB_DATA_2, SCM_SMOB_DATA_3, SCM_SMOB_FLAGS,
194 SCM_SET_SMOB_DATA_2, SCM_SET_SMOB_DATA_3, SCM_SET_SMOB_FLAGS,
195 SCM_SMOB_OBJECT, SCM_SMOB_OBJECT_2, SCM_SMOB_OBJECT_3,
196 SCM_SET_SMOB_OBJECT, SCM_SET_SMOB_OBJECT_2, SCM_SET_SMOB_OBJECT_3,
197 SCM_SMOB_OBJECT_LOC, SCM_SMOB_OBJECT_2_LOC,
198 SCM_SMOB_OBJECT_3_LOC): New.
199 * smob.c (scm_i_set_smob_flags): New function.
201 * dynl.c, dynwind.c, eval.h, fluids.h, futures.h, hashtab.h,
202 hooks.h, keywords.h, macros.h, macros.c, mallocs.c, mallocs.h,
203 random.h, regex-posix.h, root.h, srcprop.h, srcprop.c, threads.h:
204 Use SCM_SMOB_* instead of SCM_CELL_* as appropriate. Use
205 SCM_SMOB_FLAGS and SCM_SET_SMOB_FLAGS instead of accessing the
206 zeroth word directly. Use SCM_SMOB_PREDICATE as appropriate.
208 * numbers.h (SCM_I_BIG_MPZ): Use SCM_CELL_OBJECT_LOC instead of
209 taking the address of SCM_CELL_WORD_1, the latter being no longer
212 * variable.h (SCM_VARIABLE_LOC): Use SCM_CELL_OBJECT_LOC instead
213 of casting SCM_CELL_WORD_LOC.
215 2004-05-02 Kevin Ryde <user42@zip.com.au>
217 * eval.c (scm_macroexp): Add prototype, since it's not in eval.h under
218 --disable-deprecated. Reported by Andreas Vögele.
220 * filesys.c (_POSIX_C_SOURCE): Define to 199506L to get readdir_r (in
221 particular on HP-UX). Reported by Andreas Vögele.
223 * list.c (varargs.h): Remove, leave just stdarg.h which is all the
224 code has support for. Fixes building with AIX cc, which is ansi but
225 doesn't define __STDC__. Reported by Keith Crane.
226 (var_start): Remove macro, this variation no longer required.
227 (scm_list_n): Use va_start directly.
229 2004-05-01 Kevin Ryde <user42@zip.com.au>
231 * continuations.c (scm_dynthrow): Use >= instead of SCM_PTR_GE which
232 is now gone. Reported by Andreas Vögele.
234 2004-04-28 Kevin Ryde <user42@zip.com.au>
236 * backtrace.c (display_frame_expr), numbers.c (XDIGIT2UINT,
237 mem2uinteger, mem2decimal_from_point, mem2ureal): Cast char to int for
238 ctype.h tests, to avoid warnings from gcc on HP-UX about char as array
239 subscript. Reported by Andreas Vögele.
240 Also cast through unsigned char to avoid passing negatives to those
241 macros if input contains 8-bit values.
243 * num2integral.i.c (NUM2INTEGRAL): Under non-BIGMPZ_FITSP case,
244 corrections to range check for signed numbers. Remove
245 scm_remember_upto_here_1(num) from these checks, since num is used
248 * num2integral.i.c (NUM2INTEGRAL): Test BIGMPZ_FITSP with "!= 0" to
249 avoid warning from gcc 3.4. Reported by Hyperdivision.
251 * numbers.c (scm_bit_extract): Use min instead of MIN.
252 (MIN): Remove, this conflicts with similar macro defined by limits.h
253 on HP-UX. Reported by Andreas Vögele.
255 * stime.c (_POSIX_C_SOURCE): Define to 199506L to get gmtime_r (in
256 particular on HP-UX). Reported by Andreas Vögele.
258 * threads.c (scm_threads_mark_stacks): Correction sizet -> size_t.
259 Reported by Andreas Vögele.
261 * threads-plugin.h (SCM_MUTEX_MAXSIZE): Increase to 25*sizeof(long),
262 for the benefit of hpux11 where pthread_mutex_t is 88 bytes. Reported
265 2004-04-22 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
267 * eval.c (s_macro_keyword): New static identifier.
269 (scm_m_define): Change order to first create binding and
270 evaluating the expression afterwards.
272 (scm_m_set_x): Memoize complete set! expression. Only leave
273 symbols if no binding exists at memoization time. Throw error if
274 assigning to a syntactic keyword.
276 (lazy_memoize_variable): New function.
278 (CEVAL): When execution set!, perform lazy memoization if
279 unmemoized symbol is detected.
281 * modules.c (module_variable): Return variables with unbound
284 * tags.h: Fix comment.
286 2004-04-25 Kevin Ryde <user42@zip.com.au>
288 * chars.c (scm_char_upcase, scm_char_downcase, scm_c_upcase,
289 scm_c_downcase): Use ctype.h toupper and tolower. This will be useful
290 in 8-bit locales, and ensures consistency with char-upper-case? and
291 char-lower-case? which already use ctype.h.
292 (scm_c_upcase_table, scm_c_downcase_table, scm_lowers, scm_uppers):
294 * chars.c, chars.h, init.c (scm_tables_prehistory): Remove.
296 * socket.c (VALIDATE_INET6): Correction to bignum_in_ipv6_range_p
297 call. Reported by Hyperdivision.
299 * threads.c (scm_yield): Correction, actually call scm_thread_yield.
300 Reported by Hyperdivision.
302 * unif.c (s_scm_make_uve): Remove unused local variable. Reported by
305 2004-04-22 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
307 Hide the implementation of ilocs and isyms in eval.c.
309 * deprecated.h (SCM_IFRINC, SCM_ICDR, SCM_IFRAME, SCM_IDIST,
310 SCM_ICDRP), eval.c (SCM_IFRINC, SCM_ICDR, SCM_IFRAME, SCM_IDIST,
311 SCM_ICDRP), eval.h (SCM_ICDR, SCM_IFRINC, SCM_IFRAME, SCM_IDIST,
312 SCM_ICDRP): Deprecated and added to deprecated.h. Moved from
315 * deprecated.c (scm_isymnames), deprecated.h (scm_isymnames,
316 SCM_ISYMNUM, SCM_ISYMCHARS), eval.c (SCM_ISYMNUM, isymnames,
317 scm_unmemocopy, CEVAL), print.c (scm_isymnames), tags.h
318 (SCM_ISYMNUM, scm_isymnames, SCM_ISYMCHARS): Deprecated
319 scm_isymnames, SCM_ISYMNUM and SCM_ISYMCHARS and added to
320 deprecated.[hc]. Moved scm_isymnames from print.c to eval.c and
321 renamed to isymnames. Moved SCM_ISYMNUM from tags.h to eval.c and
324 * eval.c (scm_i_print_iloc, scm_i_print_isym), eval.h
325 (scm_i_print_iloc, scm_i_print_isym), print.c (scm_iprin1):
326 Extracted printing of ilocs and isyms to guile internal functions
327 scm_i_print_iloc, scm_i_print_isym of eval.c.
329 2004-04-22 Kevin Ryde <user42@zip.com.au>
331 * numbers.c (scm_bit_extract): Use SCM_SRS for signed right shift.
333 * numbers.c (scm_round): Test for x already an integer, to avoid bad
334 rounding in x+0.5 when x is a big value already an integer. In
335 certain hardware rounding cases x+0.5 can give an adjacent integer,
336 leading to that as the result, when we really just wanted x itself.
338 2004-04-19 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
340 * eval.c (scm_unmemocopy): Fixed unmemoization of let*.
342 (deval_args, CEVAL): Minor improvements: Reduced variable scopes,
343 added const qualifiers, cast intentionally unused expressions to
344 void for emphasis, improved comment.
346 2004-04-18 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
348 * tags.h (scm_tags, scm_tc8_tags, scm_tc9_flag, scm_tc8_flag,
349 scm_tc8_isym): Renamed scm_tags to scm_tc8_tags. Renamed
350 scm_tc9_flag to scm_tc8_flag. Introduced new identifier
351 scm_tc8_isym. Defined tc8-tags relative to scm_tc3_imm24.
352 Defined the tc8-tag for flags to be 0x04, which will mean that
353 SCM_BOOL_F will also have the value 0x04 instead of 0x013c. Due
354 to the reduced number of bits and the simpler bit pattern for
355 SCM_BOOL_F, certain machines may be able to use more efficient
356 processor instructions to deal with SCM_BOOL_F.
358 (SCM_ITAG9, SCM_MAKE_ITAG9, SCM_ITAG9_DATA): Removed. These have
359 never been defined in a released version, thus no need to
362 (SCM_IFLAGP, SCM_MAKIFLAG, SCM_IFLAGNUM): Flags now use tc8
365 (SCM_ISYMP, SCM_MAKISYM, SCM_ISYMNUM): Isyms now use tc8 instead
368 (SCM_MAKSPCSYM): Removed. It is almost impossible that user code
369 could have used this definition.
371 (SCM_IM_AND, SCM_IM_BEGIN, SCM_IM_CASE, SCM_IM_COND, SCM_IM_DO,
372 SCM_IM_IF, SCM_IM_LAMBDA, SCM_IM_LET, SCM_IM_LETSTAR,
373 SCM_IM_LETREC, SCM_IM_OR, SCM_IM_QUOTE, SCM_IM_SET_X): Now encoded
374 as isyms, as special isyms don't exist any more.
376 2004-04-18 Kevin Ryde <user42@zip.com.au>
378 * filesys.c (scm_readdir): Use readdir_r when available, for thread
381 * numbers.c (scm_max, scm_min): For big/real, use SCM_SWAP rather than
382 explicit swapping code.
384 2004-04-15 Kevin Ryde <user42@zip.com.au>
386 * cpp_sig_symbols.in: Add SIGSYS.
388 * list.c (scm_append_x): Use iterative style, to avoid non-tail
391 * numbers.c (scm_max, scm_min): For inum/frac, frac/inum, big/frac,
392 frac/big and frac/frac, use scm_less_p for exact comparison.
394 * numbers.c (scm_gcd): For inum/big, use mpz_gcd_ui by sharing code
397 * numbers.c (xisinf): Add a comment about solaris 7 lacking isinf.
399 2004-04-06 Han-Wen Nienhuys <hanwen@xs4all.nl>
401 * inline.h (scm_cell): use SCM_GC_CELL_WORD for checking tag.
403 * chars.h (scm_init_chars): change scm_{upcase,downcase} to
405 (SCM_MAKE_CHAR): add (unsigned char) cast. This prevents havoc
406 when hi-bit ASCII is subjected to SCM_MAKE_CHAR().
408 2004-04-06 Kevin Ryde <user42@zip.com.au>
410 * numbers.c (scm_ash): Remove stray "}" in docstring.
412 * numbers.c (scm_make_ratio): For inum/bignum integer detection, use
413 x==SCM_MOST_NEGATIVE_FIXNUM explicitly, for clarity and to avoid
414 calling mpz_cmp_ui in most cases.
416 * numbers.c (scm_quotient, scm_remainder): In inum/big, use mpz_cmp_ui
417 for big == abs(most-negative-fixnum) special case.
418 (abs_most_negative_fixnum): Remove, no longer used.
420 * scmsigs.c (scm_sigaction_for_thread): Correction to signum range
421 test, avoids SCM_VECTOR_REF outside bounds of signal_handlers on
422 calling (sigaction NSIG).
424 * simpos.c (scm_system_star): Fix execargv memory leak, merge parent
425 and fork error cases to do this.
427 2004-04-03 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
429 * eval.c (CEVAL): Don't distinguish between short and long
430 instructions when dispatching - just always dispatch on the
431 instruction code, which is common for short and long instructions.
432 Further, removed unnecessary goto statements and added comment.
434 2004-04-03 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
436 * eval.c (scm_unmemocopy): Don't distinguish between short and
437 long instructions when dispatching - just always dispatch on the
438 instruction code, which is common for short and long instructions.
439 Further, removed unnecessary goto statements, fixed indentation
440 and replaced SCM_IMP predicates by SCM_NULLP.
442 2004-04-03 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
444 * eval.c (scm_lookupcar1, CEVAL): Use SCM_ILOCP instead of
445 comparison with SCM_ILOC00. In CEVAL, eliminate goto-label
448 2004-03-31 Kevin Ryde <user42@zip.com.au>
450 * simpos.c: Include <signal.h> for SIG_IGN and friends.
452 2004-03-29 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
454 Introduce scm_debug_mode_p as a replacement for scm_debug_mode and
457 * debug.h (scm_debug_mode_p, scm_debug_mode, SCM_DEBUGGINGP),
458 eval.c (scm_debug_mode_p): Deprecated scm_debug_mode and
459 SCM_DEBUGGINGP. Provided scm_debug_mode_p instead, to have one
460 single interface that also matches the naming conventions.
461 Probably scm_debug_mode_p should be part of the private interface
464 * debug.h (scm_debug_mode_p), backtrace.c (display_error_body),
465 eval.c (SCM_APPLY, scm_trampoline_0, scm_trampoline_1,
466 scm_trampoline_2): Change uses of scm_debug_mode or SCM_DEBUGGINGP
470 Deprecate direct access to scm_ceval, scm_deval and scm_ceval_ptr:
472 * eval.h (scm_ceval, scm_deval, scm_ceval_ptr), debug.h
473 (scm_ceval_ptr): Deprecated. Moved declaration of scm_ceval_ptr
474 from debug.h to eval.h.
476 * debug.h (SCM_RESET_DEBUG_MODE): Don't access scm_ceval_ptr any
477 more, just leave it with setting scm_debug_mode_p, which is
478 equivalent for practical purposes.
480 * deprecated.h (SCM_XEVAL, SCM_XEVALCAR): Call scm_i_eval_x
481 instead of *scm_ceval_ptr. Leave all evaluating to scm_i_eval_x.
483 * gdbint.c (gdb_eval): Call scm_i_eval_x instead of scm_ceval.
485 * eval.c (ceval, deval, scm_ceval, scm_deval): Made scm_ceval
486 static and renamed it to ceval throughout. Provide a new exported
487 but deprecated function scm_ceval as a wrapper for backwards
488 compatibility. The same is done for the deval/scm_deval pair of
491 * eval.c (CEVAL, SCM_CEVAL): Renamed SCM_CEVAL to CEVAL
492 throughout. Defined CEVAL to ceval or deval, based on compilation
495 * eval.c (SCM_XEVAL, SCM_XEVALCAR): Dispatch on scm_debug_mode_p
496 to ceval and deval instead of calling *scm_ceval_ptr.
498 * eval.c (dispatching_eval): New deprecated static function.
500 * eval.c (scm_ceval_ptr): Initialized to dispatching_eval in order
501 to emulate its old behaviour as closely as possible.
504 Change the evaluator such that only expressions for which pair? is
505 true are passed to CEVAL, and such that all other expressions are
506 evaluated outside of CEVAL:
508 * eval.c (EVAL): New, provided in analogy to EVALCAR. Evaluate an
509 expression that is assumed to be memoized already. All but
510 expressions of the form '(<form> <form> ...)' are evaluated inline
511 without calling an evaluator.
513 * eval.c (SCM_XEVAL, SCM_XEVALCAR, EVALCAR): Evaluate all but
514 expressions of the form '(<form> <form> ...)' inline without
515 calling an evaluator.
517 * eval.c (scm_i_eval_x, scm_i_eval, scm_ceval, scm_deval): Handle
518 the special case of unmemoized symbols passed on the top level.
520 * eval.c (CEVAL): Change calls to CEVAL to EVAL, except where it
521 is known that the expression passed to CEVAL is of the form
522 '(<form> <form> ...)'. Remove handling of the tc7-objects, since
523 now it is known that the input expression of CEVAL is a pair.
525 2004-03-29 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
527 * eval.c (is_self_quoting_p): New static function.

537 * list.c (s_scm_filter): remove "pointer" from doc string.
539 * gc.h (SCM_GC_CELL_TYPE): SCM_GC_CELL_TYPE uses SCM_GC_CELL_OBJECT.
541 * goops.h (SCM_NUMBER_OF_SLOTS): don't SCM_UNPACK the result.
543 * backtrace.c ("display_backtrace_body"): SCM_PACK before SCM_EQ_P
544 (display_frame): idem.
545 (display_backtrace_file_and_line): idem.
547 * tags.h (SCM_UNPACK): stricter typechecking on SCM_UNPACK
550 2004-03-26 Kevin Ryde <user42@zip.com.au>
552 * filesys.c (scm_getcwd, scm_readlink): Avoid memory leak on errors.
554 * numbers.c (scm_modulo): For inum/big and big/big, remove test of
555 big==0 since that never occurs.
557 * numbers.c, numbers.h (scm_modulo_expt): Renamed from
558 scm_modular_expt, matching scheme level name `modulo-expt'.
560 * numbers.c (scm_modular_expt): Return a negative remainder for a
561 negative divisor, the same as `modulo' does.
563 2004-03-26 Eric Hanchrow <offby1@blarg.net>
565 * numbers.c, numbers.h (scm_modular_expt): New function.
567 2004-03-25 Kevin Ryde <user42@zip.com.au>
569 * numbers.c (scm_min, scm_max): Correction to big/real and real/big,
570 return inexact as required by r5rs.
572 2004-03-24 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
574 * eval.c: Separated some definitions relevant for execution from
575 the memoization part of the file.
577 (copy_tree): New static function
579 (scm_copy_tree): Rewritten to fix two kinds or bugs: First, cyclic
580 structures are detected now and will lead to an exception instead
581 of forcing guile to run in an endless loop, using up all the
582 system's memory. Second, arrays in the cdr of an improper list
583 are now copied. See the new test cases in eval.test.
585 2004-03-24 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
587 * posix.c (scm_gethostname): Make sure len is initialised before
588 it is used. Restructured to (hopefully) represent possible
589 configurations more clearly in the code. Added unwind handler.
591 2004-03-23 Kevin Ryde <user42@zip.com.au>
593 * posix.c (scm_gethostname): Use sysconf(_SC_HOST_NAME_MAX) and/or
594 MAXHOSTNAMELEN when available.
596 2004-03-21 Marius Vollmer <mvo@zagadka.de>
598 * read.c (skip_scsh_block_comment): Also recognize '\r' as a line
599 terminator. Rewritten the logic as a state machine, I must have
600 been doing too much VHDL lately...
602 * eval.c (scm_ceval, scm_deval): Explicitely evaluate ports to
603 themselves. Thanks to Han-Wen Nienhuys!
605 * list.c: Changed docstrings so that they no longer talk about
606 returning 'pointers' to something.
608 2004-03-20 Han-Wen Nienhuys <hanwen@xs4all.nl>
610 * gc.c: remove set_debug_cell_accesses! when
611 SCM_DEBUG_CELL_ACCESSES is not defined. Scheme source code should
612 use (if (defined? 'set-debug-cell-accesses!) .. ) to switch on
613 debugging conditionally.
615 2004-03-21 Kevin Ryde <user42@zip.com.au>
617 * stime.c (scm_gmtime): Use gmtime_r when available, for thread safety.
619 2004-03-20 Kevin Ryde <user42@zip.com.au>
621 * posix.c (scm_gethostname): Preserve errno across free() call.
623 2004-03-18 Han-Wen Nienhuys <hanwen@xs4all.nl>
625 * gc-card.c (sweep_card): use SCM_GC_SET_CELL_WORD for setting
628 2004-03-14 Kevin Ryde <user42@zip.com.au>
630 * stime.c: Define _GNU_SOURCE for strptime prototype from glibc.

633 2004-03-07 Kevin Ryde <user42@zip.com.au>
635 * stime.c (scm_gmtime): Return bd_time->tm_zone when available, rather
637 (filltime): Make zname parameter "const".
639 2004-03-03 Mikael Djurfeldt <mdj@chunk.mit.edu>
641 * threads.c, threads.h (scm_c_scm2thread): New function.
643 2004-02-29 Kevin Ryde <user42@zip.com.au>
645 * numbers.c (guile_ieee_init): Use C99 INFINITY and NAN when
646 available. Test HAVE_DINFINITY and HAVE_DQNAN for those globals, in
647 particular don't assume "defined (__alpha__) && ! defined (linux)"
648 means OSF. Remove "SCO" code, which was not really SCO specific and
649 which John W. Eaton advises should be long past being needed.
651 * posix.c (scm_execl, scm_execlp, scm_execle): Avoid memory leak under
654 2004-02-24 Kevin Ryde <user42@zip.com.au>
656 * posix.c (scm_cuserid): Use a private result buffer, for thread safe.
658 2004-02-22 Kevin Ryde <user42@zip.com.au>
660 * numbers.c (scm_max, scm_min): For one arg, dispatch to generic for
661 complex, same as for two args. (Handle only inum, big, real, frac).
663 2004-02-21 Kevin Ryde <user42@zip.com.au>
665 * posix.c (scm_crypt): Use new HAVE_CRYPT.
666 (<crypt.h>): Remove HAVE_LIBCRYPT condition.
667 Reported by Andreas Voegele.
669 2004-02-20 Neil Jerram <neil@ossau.uklinux.net>
671 * list.c (scm_list_n): Add #if SCM_DEBUG_CELL_ACCESSES_P around
674 * read.c (scm_lreadparen): Removed.
675 (scm_lreadparen1): Renamed scm_i_lreadparen.
677 2004-02-20 Han-Wen Nienhuys <hanwen@xs4all.nl>
679 * list.c (scm_list_n): validate non-immediate arguments;
680 this will catch forgotten a SCM_UNDEFINED.
682 2004-02-18 Marius Vollmer <mvo@zagadka.de>
684 * gc.h (scm_gc_cells_collected): Removed duplicated declaration.
685 Thanks to Bill Schottstaedt!
687 * socket.h (scm_gethost): Removed prototype it is already in
688 "net_db.h". Thanks to Bill Schottstaedt!
690 2004-02-18 Kevin Ryde <user42@zip.com.au>
692 * num2integral.i.c (INTEGRAL2BIG): WORDS_BIGENDIAN not right for word
693 order parameter to mpz_import, in fact with just one word there's no
694 order to worry about at all.
696 * numbers.c (scm_num_eq_p): For real==frac, complex==frac, frac==real
697 and frac==complex, make an exact comparison rather than converting
698 with fraction2double.
700 * posix.c, putenv.c, stime.c (environ): Use _NSGetEnviron in Darwin
701 shared library, since environ is not directly available there.
703 * script.c (scm_shell_usage): Print to stdout for --help, per GNU
706 * stime.c (scm_localtime, scm_gmtime, scm_mktime): Provide a default
707 errno EINVAL in case localtime and gmtime don't set it.
708 (scm_mktime, scm_strptime): Forcibly use errno EINVAL for our
709 SCM_SYSERROR, since mktime and strptime generally don't set errno.
711 2004-02-16 Kevin Ryde <kevin@swox.se>
713 * gc-malloc.c (scm_done_malloc, scm_done_free): Allow negative sizes,
714 which were permitted in the past for these.
716 * num2float.i.c (NUM2FLOAT): Expand isfinite to !xisinf, as per
717 previous change to numbers.c.
719 * script.c (scm_shell_usage): Print bug-guile email address, as per
720 GNU standard. Reported by Han-Wen Nienhuys.
722 2004-02-13 Mikael Djurfeldt <djurfeldt@nada.kth.se>
724 * unif.c (scm_make_uve): Removed local variable and simplified
725 code in order to avoid compiler used uninitialized warnings.
727 * hashtab.c, hashtab.h (scm_hash_map_to_list): Renamed from
729 (scm_hash_fold): Use scm_call_3 directly in the call to
730 scm_internal_hash_fold instead of going via fold_proc (which is
732 (scm_hash_for_each): Use a trampoline +
733 scm_internal_hash_for_each_handle.
734 (scm_internal_hash_for_each_handle, scm_hash_for_each_handle): New
737 2004-02-12 Kevin Ryde <user42@zip.com.au>

740 (scm_set_port_line_x): In docstring, note first line is 0.
741 (scm_port_column): In docstring, there's no default to current input
742 port, and remove shared port-line @defun.
743 (scm_set_port_column_x): In docstring, there's no default to current
744 input port, note first column is 0, remove shared set-port-line!
747 * ramap.c (scm_array_fill_x): For fvect and dvect, use scm_num2dbl to
748 convert args the same way that array-set! does.
750 * unif.c (scm_make_uve, scm_array_p): Allow fraction 1/3 as prototype
752 (scm_array_p): Add missing "break"s in switch, fix llvect test look
753 for "l" not "s", fix dvect to be false for singp(prot) since such a
755 (scm_array_prototype): Return 1/3 for dvect, rather than 0.33..33.
756 (exactly_one_third): New variable.
757 (scm_init_unif): Initialize it.
759 2004-02-10 Neil Jerram <neil@ossau.uklinux.net>
761 * read.c (scm_read_opts): Change `escaped-parens' to
764 2004-02-08 Neil Jerram <neil@ossau.uklinux.net>
766 * read.c (scm_read_opts): New opts `elisp-vectors' and
769 (scm_lreadr): Use scm_lreadparen1 instead of scm_lreadparen. Make
770 handling of elisp vector syntax dependent on SCM_ENABLE_ELISP and
771 `elisp-vectors' option instead of SCM_ELISP_READ_EXTENSIONS.
772 Allow "\(" and "\)" in strings when SCM_ENABLE_ELISP defined and
773 `escaped-parens' option set.
774 (scm_read_token): If elisp vector syntax active, disallow [ and ]
776 (scm_lreadparen): Rewrite as interface to scm_lreadparen1.
777 (scm_lreadparen1): New.
779 * read.h: Remove conditionally compiled last arg to
781 (SCM_ELISP_VECTORS_P, SCM_ESCAPED_PARENS_P): New.
783 2004-01-23 Han-Wen Nienhuys <hanwen@xs4all.nl>
785 * eval.c (m_expand_body): remove stray variable new_body.
787 2004-01-22 Marius Vollmer <mvo@zagadka.de>
789 * eval.c (m_expand_body): Rewrite the expression in place (by
790 overwriting FORMS) also when a letrec is constructed, not only
791 when no definitions are found. Do not return rewritten expression
792 to emphasize the in-place rewriting. Changed all users.
794 2004-01-19 Han-Wen Nienhuys <hanwen@xs4all.nl>
796 * gc.c: add protected_object_count, a number that is dumped from
799 2004-01-11 Marius Vollmer <mvo@zagadka.de>
801 * dynwind.h, dynwind.c (scm_frame_unwind,
802 scm_frame_unwind_handler): Renamed and changed all uses.
803 (scm_frame_rewind, scm_frame_rewind_handler): Likewise.
805 2004-01-11 Kevin Ryde <user42@zip.com.au>
807 * unif.c (scm_bit_count, scm_bit_position, s_scm_bit_set_star_x,
808 s_scm_bit_count_star, s_scm_bit_invert_x): Clarify docstrings, as per
809 changes made to scheme-compound.texi.
811 2004-01-10 Marius Vollmer <mvo@zagadka.de>
813 * print.c (scm_print_symbol_name): Handle #{`foo}#, #{,foo}#,
814 #{.}#, and all numeric strings specially. Thanks to Paul Jarc!
816 * guile-snarf.in: Use mkdir to create a unique temporary directory
817 that we can safely use. Thanks to Stefan Nordhausen!
819 2004-01-07 Marius Vollmer <marius.vollmer@uni-dortmund.de>
821 * dynwind.h, dynwind.c (scm_i_dowinds): Removed 'explicit'
822 argument since it is always zero now. Changed all callers.
823 Removed code for handling fluids.
825 * fluids.c (scm_c_with_fluids): Use frames instead of adding to
826 the wind chain explicitely. Use scm_c_with_fluid for the common
827 case of only one fluid.
828 (scm_with_fluid): New.
829 (scm_c_with_fluid): Use frames instead of scm_c_with_fluids.
831 * fluids.h, fluids.c (scm_frame_fluid): New.
832 (scm_with_fluid): New.
833 (scm_i_swap_fluids, scm_i_swap_fluids_reverse): Removed.
835 * dynwind.c (scm_frame_end): Do not use scm_i_dowinds. Instead,
836 do the unwinding directly. It is simple enough.
838 * dynwind.h, dynwind.c: Did the following renamings:
839 scm_begin_frame -> scm_frame_begin,
840 scm_end_frame -> scm_frame_end,
841 scm_on_unwind -> scm_frame_unwind,
842 scm_on_rewind -> scm_frame_rewind,
843 scm_on_unwind_with_scm -> scm_frame_unwind_with_scm,
844 scm_on_rewind_with_scm -> scm_frame_rewind_with_scm.
847 * aync.h, async.c: Did the follwing renamings:
848 scm_with_blocked_asyncs -> scm_frame_block_asyncs,
849 scm_with_unblocked_asyncs -> scm_frame_unblock_asyncs.
852 * ports.h, ports.c: Did the follwing renamings:
853 scm_with_current_input_port -> scm_frame_current_input_port,
854 scm_with_current_output_port -> scm_frame_current_output_port,
855 scm_with_current_error_port -> scm_frame_current_error_port.
858 2004-01-07 Kevin Ryde <user42@zip.com.au>
860 * numbers.c (s_bignum): Remove, not used since gmp bignums.
861 Reported by Richard Todd.
863 * threads-plugin.h (SCM_MUTEX_MAXSIZE): Increase to 12*sizeof(long),
864 for the benefit of powerpc-apple-darwin5.5. Reported by Richard Todd.
866 * unif.c (scm_aind): Test SCM_CONSP rather than !SCM_NULLP while
867 traversing the args list, fixes segv if an improper list is given.
868 Reported by Rouben Rostamian.
870 2004-01-06 Marius Vollmer <marius.vollmer@uni-dortmund.de>
872 * ports.c (swap_ports, scm_with_current_foo_port): Do not allocate
873 swap_data on stack, use a 'malloc obj'.
875 * fluids.h, fluids.c (scm_make_initial_fluids, scm_copy_fluids,
876 scm_swap_fluids, scm_swap_fluids_reverse): Renamed to
877 scm_i_... since they are internal. Changed all uses.
879 * dynwind.c (frame_print): Removed, use the default printer.
880 (WINDER_F_MARK, WINDER_MARK_P, winder_mark): New.
881 (scm_on_unwind_with_scm, scm_on_rewind_with_scm): New. Use above
882 to protect SCM values.
884 * dynwind.h (SCM_F_WIND_EXPLICITELY,
885 SCM_F_WIND_EXPLICITLY): It's "explicitly" not "explicitely", damn.
887 (scm_on_unwind_with_scm, scm_on_rewind_with_scm): New.
889 2004-01-05 Marius Vollmer <mvo@zagadka.de>
891 * ports.h, ports.c (scm_with_current_input_port,
892 scm_with_current_output_port, scm_with_current_error_port): New.

895 scm_with_unblocked_asyncs): New.
897 2004-01-03 Marius Vollmer <mvo@zagadka.de>
899 * dynwind.h, scm_dynwind.c (scm_t_frame_flags, scm_t_wind_flags,
900 scm_begin_frame, scm_end_frame, scm_on_unwind, scm_on_rewind):
902 (scm_dowinds, scm_i_dowinds): scm_dowinds has been renamed to
903 scm_i_dowinds and extended to handle frames and to invoke a 'turn'
904 function when the outermost wind point has been reached. The
905 latter is used to copy a continuation stack at the right time.
906 scm_dowinds remains available.
907 (SCM_GUARDSP, SCM_BEFORE_GUARD, SCM_AFTER_GUARD, SCM_GUARD_DATA,
908 tc16_guard, guards_print): Removed.
909 (scm_internal_dynamic_wind): Reimplemented using frames.
911 * continuations.c (copy_stack): New, do only the stack copying
912 part of copy_stack_and_call.
913 (copy_stack_and_call): Copy the stack after unwinding and before
915 (scm_dynthrow): Do not call scm_dowinds, this is now done by
918 2004-01-04 Kevin Ryde <user42@zip.com.au>
920 * numbers.c (scm_less_p): Don't convert frac to float for compares,
921 can give bad results due to rounding.
923 * stime.c (scm_current_time, scm_gettimeofday): Add a comment about
924 setzone/restorezone protection for DOS.
926 2003-12-26 Marius Vollmer <mvo@zagadka.de>
928 * gen-scmconfig.h.in, gen-scmconfig.c: Arrange for scm_t_intmax
929 and scm_t_uintmax to be defined in scmconfig.h
931 2003-12-03 Kevin Ryde <user42@zip.com.au>
933 * numbers.c (scm_less_p): Remove spurious xisnan from frac+big case.
935 * numbers.c (scm_make_ratio): Check for numerator equal to
936 SCM_MOST_NEGATIVE_FIXNUM and bignum denominator the negative of that,
939 * numbers.c (scm_real_part): Return fraction unchanged rather than
940 converting to flonum.
942 2003-11-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
944 * modules.c (module_variable): Fixed (and thus simplified) the
945 definition of SCM_BOUND_THING_P to reflect the fact that since
946 after the 1.4 series of guile, obarrays only hold variable
949 2003-11-30 Marius Vollmer <mvo@zagadka.de>
951 * numbers.c (scm_logand): It's "#b...", not "#\b...".
955 * read.c (scm_lreadr): Signal an error for invalid escape
956 sequences in strings. Code cleanups too.
958 * print.c (scm_iprin1): use \xNN hexadecimal sequences when
959 writing control characters in strings.
961 2003-11-21 Marius Vollmer <mvo@zagadka.de>
963 * ports.c (scm_drain_input): Bug fix: only access the port after
964 checking that it indeed is one.
966 2003-11-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
968 * eval.c (s_bad_define): New static identifier.
970 (m_body): Fixed comment.
972 (scm_m_define): Don't generate memoized code for definitions that
973 are not on the top level. As a consequence, no memoized code at
974 all is generated for definitions any more: Top level definitions
975 are executed immediately during memoization and internal
976 definitions are handled separately in m_expand_body.
978 (scm_unmemocopy, unmemocopy): Removed code for unmemoizing
979 definitions. Consequently, there is no unmemoizing code any more
980 that might modify the environment. Thus, the old scm_unmemocopy
981 is removed and the old unmemocopy is renamed to scm_unmemocopy.
983 (SCM_CEVAL): The SCM_IM_DEFINE keyword can no longer occur in
984 memoized code. Call EVALCAR for continuations. Prefer !SCM_NULLP
985 over SCM_NIMP in places, where the argument is known to be part of
988 2003-11-21 Kevin Ryde <user42@zip.com.au>
990 * numbers.c (scm_abs): Allocate a new real only for negatives, as done
993 * numbers.c (scm_bit_extract): Use mpz functions, rearrange inum case
994 to share some shifting.
996 * numbers.c (scm_integer_expt): Don't mpz_init after scm_i_clonebig or
997 scm_i_mkbig, since they do so already. Don't mpz_clear a bignum SCM,
1000 2003-11-19 Marius Vollmer <mvo@zagadka.de>
1002 * numbers.c (scm_make_ratio): Rewritten to have a simpler
1003 structure. Previously, not all cases with a negative denominator
1006 * numbers.c (mem2decimal_from_point): use scm_divide instead of
1007 scm_divide2real when forming the fractional part. This allows
1008 "#e1.2" to yield 6/5.
1010 * numbers.c (scm_i_fraction_equalp): Do not treat the return value
1011 of scm_equal_p as a C boolean, use SCM_FALSEP. Previously, all
1012 fractions were equal to each other regardless of value. Ooops.
1014 * numbers.c (scm_rationalize): Return an inexact result when given
1017 * numbers.c (scm_exact_p, scm_inexact_p): Throw error for

1035 (scm_round_number, scm_truncate_number, scm_ceiling, scm_floor):
1036 New exact functions that replace the inexact 'dsubr'
1038 (scm_numerator, scm_denominator): New.
1040 * numbers.h (SCM_NUMP): Recognize fractions.
1041 (SCM_FRACTIONP, SCM_SLOPPY_FRACTIONP, SCM_FRACTION_NUMERATOR,
1042 SCM_FRACTION_DENOMINATOR, SCM_FRACTION_SET_NUMERATOR,

1044 SCM_FRACTION_REDUCED_SET, SCM_FRACTION_REDUCED_CLEAR,
1045 SCM_FRACTION_REDUCED): New.
1046 (scm_floor, scm_ceiling, scm_truncate_number, scm_round_number):
1048 (scm_make_ratio, scm_rationalize, scm_numerator, scm_denominator,
1049 scm_rational_p): New prototypes.
1050 (scm_i_dbl2num, scm_i_fraction2double, scm_i_fraction_equalp,
1051 scm_i_print_fraction): New prototypes.
1053 * goops.c (create_standard_classes): Create "<fraction>" class.
1055 * gc-mark.c (scm_gc_mark_dependencies): Handle fractions.

1069 direct typedef of long_long and ulong_long inside deprecated block
1072 * deprecated.h: move long_long and ulong_long definitions to
1073 gen-scmconfig.c so that we don't need to add SCM_SIZEOF___INT64
1074 and SCM_SIZEOF_UNSIGNED___INT64 to the public namespace.

1087 the "-e" option instead of scm_str2symbol. This allows things
1088 like (@ ...) to be specified for the entry point.

1292 (scm_m_quote, unmemocopy): As an optimization, vector constants
1293 are now inserted unquoted into the memoized code. During
1294 unmemoization the quotes are added again to provide syntactically
1297 2003-10-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
1299 * eval.c (scm_m_let, scm_m_letstar, scm_m_letrec,

1368 * eval.c (s_missing_expression, s_bad_variable): New static
1371 (scm_m_define): Use ASSERT_SYNTAX to signal syntax errors. Prefer
1372 R5RS terminology for the naming of variables. Be more specific

1382 (s_extra_case_clause): Removed.
1384 (scm_m_case, scm_m_cond): If a clause appears after an else
1385 clause, report a misplaced else clause.
1387 (scm_m_cond): Use ASSERT_SYNTAX to signal syntax errors. Be more
1388 specific about the kind of error that was detected. Handle bound
1389 'else and '=>. Avoid unnecessary consing when creating the
1392 (scm_m_cond, unmemocopy, SCM_CEVAL): Use SCM_IM_ELSE to memoize
1393 the syntactic keyword 'else and SCM_IM_ARROW to memoize the
1394 syntactic keyword '=>.

1431 2003-10-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1433 * smob.h (scm_make_smob_type): Made the declaration match the
1436 2003-10-07 Marius Vollmer <mvo@zagadka.de>
1438 * goops.c, objects.h, smob.c, smob.h: Make type names char
1439 const * instead of char *. Thanks to Paul Jarc!
1441 2003-10-02 Kevin Ryde <user42@zip.com.au>
1443 * strports.c (scm_call_with_output_string): scm_get_output_string
1444 rather than scm_strport_to_string, so as to guard against the port
1445 having been closed by the called procedure. Reported by Nic Ferrier.
1447 2003-09-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
1449 * numbers.h (SCM_INEXACTP): Removed uses of SCM_TYP16S.
1451 * tags.h, deprecated.h (SCM_TYP16S): Deprecated and moved from
1452 tags.h to deprecated.h.
1454 2003-09-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
1456 This set of patches introduces a new tc7 code scm_tc7_number for
1457 numbers. Bignums, reals and complex numbers are turned from smobs
1458 into subtypes of scm_tc7_number.
1460 * tags.h (scm_tc7_number): New.
1462 * eq.c (scm_equal_p), eval.c (SCM_CEVAL), evalext.c
1463 (scm_self_evaluating_p), gc-card.c (scm_i_sweep_card), gc-mark.c
1464 (scm_gc_mark_dependencies), goops.c (create_smob_classes), hash.c
1465 (scm_hasher), numbers.c, numbers.h (SCM_NUMP), objects.c
1466 (scm_class_of), print.c (scm_iprin1), smob.c
1467 (scm_smob_prehistory): Don't handle bignums, reals and complex
1468 numbers as subtypes of scm_tc7_smob any more.
1470 * numbers.h, tags.h (scm_tc16_big, scm_tc16_real,
1471 scm_tc16_complex): Moved definitions from tags.h to numbers.h.
1473 2003-09-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
1475 * numbers.c (scm_make_complex), gc-card.c (scm_i_sweep_card): Use
1476 sizeof (scm_t_complex) to determine the memory size of the
1477 malloc'd area for complex numbers.
1479 2003-09-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
1481 * numbers.c (scm_bigequal): Fixed.
1483 2003-09-16 Marius Vollmer <mvo@zagadka.de>
1485 * stime.c (scm_current_time): 'time' does not set errno so don't
1486 use SCM_SYSERROR for reporting errors.
1488 2003-09-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
1490 This set of patches eliminates the dependency between the
1491 implementation of evaluator specific memoization codes and special
1492 constants like #f, '() etc. ('flags'), which are not evaluator
1493 specific. The goal is to remove definitions of evaluator
1494 memoization codes completely from the public interface. This will
1495 make it possible to experiment more freely with optimizations of
1496 guile's internal representation of memoized code.
1498 * objects.c (scm_class_of): Eliminate dependency on SCM_ISYMNUM.
1500 * print.c (iflagnames): New array, holding the printed names of
1501 guile's special constants ('flags').
1503 (scm_isymnames): Now holds only the printed names of the
1506 (scm_iprin1): Separate the handling of memoization codes and
1507 guile's special constants.
1509 * tags.h (scm_tc9_flag, SCM_ITAG9, SCM_MAKE_ITAG9, SCM_ITAG9_DATA,
1512 (scm_tc8_char, scm_tc8_iloc, SCM_BOOL_F, SCM_BOOL_T,
1513 SCM_UNDEFINED, SCM_EOF_VAL, SCM_EOL, SCM_UNSPECIFIED, SCM_UNBOUND,
1514 SCM_ELISP_NIL, SCM_IM_DISPATCH, SCM_IM_SLOT_REF,
1515 SCM_IM_SLOT_SET_X, SCM_IM_DELAY, SCM_IM_FUTURE,
1516 SCM_IM_CALL_WITH_VALUES, SCM_IM_NIL_COND, SCM_IM_BIND): Changed
1519 (SCM_IFLAGP): SCM_IFLAGP now only tests for flags.
1521 (SCM_IFLAGP, SCM_MAKIFLAG, SCM_IFLAGNUM): Generalized to use the
1522 tc9 macros and scm_tc9_flag.
1524 2003-09-15 Marius Vollmer <mvo@zagadka.de>
1526 * posix.c (scm_setgroups): Check that the gid list is not too
1527 long. Thanks to Paul Jarc!
1529 2003-09-14 Dirk Herrmann <D.Herrmann@tu-bs.de>
1531 * tags.h: Reduced the number of short instructions from 14 to 13.
1532 The typecode of the former 14th short instruction is now used to
1533 represent long instructions. Changed some comments to reflect
1536 (SCM_MAKISYM): ISYMs get a new tc7 code, namely the one that was
1537 previously used by SCM_IM_DEFINE.
1539 (SCM_IM_DEFINE): Turned into a long instruction.
1541 * eval.c (unmemocopy, SCM_CEVAL): Treat SCM_IM_DEFINE as a long
1544 * eval.c (SCM_CEVAL): Since characters and iflags have now a tc7
1545 code that is separate from all instructions, one level of dispatch
1546 for long instructions can be eliminated.
1548 * print.c (scm_isymnames): Removed some commented code.
1550 2003-09-12 Marius Vollmer <mvo@zagadka.de>
1552 * __scm.h (SCM_FENCE): Use __memory_barrier with the Intel
1555 * hashtab.h (scm_tc16_hashtable): Added "extern" declaration.
1557 * modules.c (scm_module_reverse_lookup): Check that the obarray
1558 really is a hashtable and do nothing if not.
1560 * inline.h: Use "extern inline" only with GCC. Use "static
1563 2003-09-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
1565 * numbers.h (SCM_INEXACTP, SCM_REALP, SCM_COMPLEXP): Removed uses
1566 of SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP.
1568 * numbers.h, deprecated.h (SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP,
1569 SCM_SLOPPY_COMPLEXP): Deprecated and moved from numbers.h to
1572 2003-09-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
1574 * eq.c (scm_eqv_p, scm_equal_p): Removed uses of
1575 SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP.
1577 * eq.c (scm_eqv_p, scm_equal_p): Reordered comparisons from
1578 0.0==some_expression to some_expression==0.0. The latter is
1579 better readable. The former is preferred by some people, since it
1580 leads to a compiler error when confusing == with =. However, when
1581 using gcc, a warning will be issued if in an if-statement an
1582 assigment appears. Since many Guile developers are using gcc,
1583 such errors will not remain unnoticed anyway. We can therefore
1584 focus on better readability.
1586 2003-09-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
1588 * tags.h: Added description of Guile's type system. Removed some
1589 old and misleading comments.
1591 2003-09-04 Dirk Herrmann <D.Herrmann@tu-bs.de>

1658 * properties.c (scm_primitive_property_ref): In docstring, note
1659 parameters to not-found-proc, use hyphens rather than underscores for

1680 compiles when SCM_C_INLINE is undefined.
1682 2003-07-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
1684 * __scm.h: Reformulated the architecture and compiler properties
1685 in terms of properties of scm_t_bits and SCM variables rather than
1686 in terms of c standard types. This is since it is not known which
1687 of the standard types scm_t_bits and SCM variables will be defined
1690 2003-07-24 Kevin Ryde <user42@zip.com.au>
1692 * numbers.c (scm_angle): Use scm_flo0 for non-negative inum, bignum
1695 2003-07-18 Kevin Ryde <user42@zip.com.au>
1697 * numbers.c (scm_product): In complex * bignum, correction to

1720 2003-07-08 Matthias Koeppe <mkoeppe@merkur.math.uni-magdeburg.de>
1722 * tags.h (scm_t_bits, scm_t_signed_bits, etc): Avoid solaris empty
1723 defines of INTPTR_MAX and UINTPTR_MAX, combine conditionals for
1724 scm_t_bits and scm_t_signed_bits to avoid any chance of one and not
1725 the other using intptr_t.
1727 2003-07-08 Kevin Ryde <user42@zip.com.au>
1729 * numbers.c (scm_make_polar): Use sincos, when available.
1730 (scm_magnitude): Use hypot.

1740 * gc-malloc.c (decrease_mtrigger): new function
1741 (increase_mtrigger): new function, separate debug registering and
1742 mtrigger administration.
1743 (scm_gc_realloc): bugfix: do mtrigger administration before the
1744 actual realloc, for the realloc might invalidate a GC-d segment of
1745 memory. Thanks to Sam Hocevar for pointing this out.
1746 (scm_gc_realloc): use scm_malloc_reregister instead of
1747 unregistering and registering in sequence.
1749 2003-07-03 Han-Wen Nienhuys <hanwen@cs.uu.nl>
1751 * __scm.h (SCM_ASSERT): change "else" expansion to "do { } while (0)"

1777 * numbers.c (_GNU_SOURCE): #define, to get C99 things.
1778 (scm_asinh, scm_acosh, scm_atanh, scm_truncate, $asinh, $acosh,
1779 $atanh, truncate): Use C library asinh, acosh, atanh and trunc, when

1796 to be functions instead of macros.
1798 * threads.c: Conditionalized inclusion of <sys/time.h> and
1800 (scm_getspecific, scm_setspecific): Made these two function
1801 real part of the API.
1803 * posix.c (s_scm_putenv): Added some code to make a
1804 (putenv "FOO="), i.e. setting an empty string, work also on
1805 Win32 systems. Thanks to Kevin Ryde for the proposal.
1807 2003-06-12 Kevin Ryde <user42@zip.com.au>

1832 2003-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1834 * eval.c: Partially undid my patch from 2003-05-31. This patch
1835 caused the segfault referenced in the previous changelog entry.

1839 * tags.h: Fixed comment about the immediate type code layout.
1841 * eval.c: Fixed handling of non-special instructions. Without
1842 this patch, guile will segfault on (#\0) and similar instructions.
1844 2003-06-05 Kevin Ryde <user42@zip.com.au>
1846 * numbers.c (scm_max, scm_min): For inum, bignum and real, if other
1847 operand is NaN, then return NaN. Also avoid passing NaN to mpz_cmp_d.
1849 * read.c (scm_input_error): Pass arg list parameter to scm_error_scm,
1850 rather than SCM_EOL. Needed by "Unknown # object" case in scm_lreadr.

1854 * __scm.h, gc-card.c (SCM_DEBUG_DEBUGGER_SUPPORT,
1855 SCM_DEBUG_DEBUGGING_SUPPORT): Renamed macro

1867 * deprecated.h, eval.c, eval.h (SCM_ILOC00, SCM_IDINC,
1868 SCM_IDSTMSK): Deprecated. The macro definitions are moved from
1869 eval.h into eval.c and a copy is placed into deprecated.h.
1871 * eval.c, eval.h (SCM_MAKE_ILOC): Removed from eval.h and placed
1872 into eval.c. This definition was not part of the API in any
1873 officially released version of guile and thus does not need to go
1874 through a phase of deprecation.

1881 definitions are make static and renamed from scm_s_xxx to s_xxx.
1882 In deprecated.c the original definitions are copied.
1884 * deprecated.h, eval.c, eval (SCM_EVALIM2, SCM_EVALIM, SCM_XEVAL,
1885 SCM_XEVALCAR): Deprecated. The macro definitions are moved from
1886 eval.h into eval.c and a copy (slightly modified to work in user
1887 code) is placed into deprecated.h.
1889 * eval.c: Use the local static s_xxx definitions instead of the
1890 scm_s_xxx definitions throughout.
1892 2003-06-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
1894 This set of patches separates the representation of the cxr family
1895 of functions (car, cdr etc.) from the dsubr family of functions
1896 (i. e. functions that take a double precision floating point
1897 argument). Further, the algorithm for handling the cxr function

1911 * eval.c (SCM_CEVAL, SCM_APPLY, call_cxr_1), pairs.c
1912 (scm_init_pairs): Make use of the (now usable) second cell element
1913 of a scm_tc7_cxr function to implement the cxr family of functions
1916 2003-05-31 Dirk Herrmann <D.Herrmann@tu-bs.de>
1918 * eval.c (SCM_CEVAL, SCM_APPLY, scm_trampoline_0,
1919 scm_trampoline_1, scm_trampoline_2): Postpone error cases to the
1920 end of an if-else-if-sequence of checks.
1922 2003-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
1924 * eval.c (SCM_CEVAL): Improved readability of call-with-values
1925 execution. Generalize apply_closure to apply_proc and use that

1954 * posix.c (s_scm_putenv): Disable use of unsetenv() for the
1957 * modules.c (s_scm_module_import_interface): Renamed local
1958 variable interface to _interface. Seems like 'interface'
1959 is a special compiler directive for the mingw32 compiler.
1961 * mkstemp.c: Provide prototype to avoid compiler warning.
1963 * load.c (s_scm_search_path): Fixed absolute and relative
1964 path detections for native Windows platforms.

2039 a compilation error if error-on-warning is enabled).
2041 2003-05-17 Marius Vollmer <mvo@zagadka.de>
2043 * c-tokenize.lex: Gobble up complete lines after a '#'. This
2044 removes preprocessor directives from the snarfage that might
2045 otherwise confuse us. These directives appear when compiling with

2088 * numbers.c (scm_num_eq_p, scm_less_p): Don't pass NaN to mpz_cmp_d.
2090 * numbers.c (scm_integer_length): On negative bignums, adjust
2091 mpz_sizeinbase to account for it looking at absolute value where we
2092 want ones-complement.
2094 * numbers.c (scm_gcd): In bignum/inum, don't pass yy==0 to mpz_gcd_ui
2095 since we're only using the ulong return value, and x might not fit.
2097 2003-05-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
2099 * eval.c, eval.h, read.c, read.h (scm_sym_dot): Moved from eval to

2110 * numbers.c (scm_difference): In inum - bignum, handle negative inum.
2111 (scm_logcount): Use mpz_com, not mpz_neg.
2113 2003-05-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
2115 The purpose of this patch is to make guile's internal memoizers
2116 distinguishable from memoizing macros created on the scheme level
2117 or from user provided primitive memoizing macros. The reason is,
2118 that the internal memoizers are the only ones that are allowed to
2119 transform their scheme input into memoizer byte code, while all
2120 other memoizing macros may only transform scheme code into new
2123 To achieve this, a new macro type 'builtin-macro!' is introduced.
2124 Currently, 'builtin-macro!'s are handled as memoizing macros, but
2125 this will change when the memoizer and executor are separated.
2127 * macros.[ch] (scm_i_makbimacro): New.
2129 * macros.h (SCM_BUILTIN_MACRO_P): New.
2131 * macros.c (macro_print, scm_macro_type): Support builtin-macro!s.
2133 * eval.c, goops.c: All of guile's primitive memoizing macros are
2134 primitive builtin-macros now.
2136 * eval.c (scm_macroexp, SCM_CEVAL): Make sure the primitive
2137 builtin-macros are handled equally to memoizing macros.
2139 2003-05-04 Marius Vollmer <mvo@zagadka.de>
2141 * throw.c (scm_ithrow): Remove "asm volatile" hack. It used to
2142 work around a bug in GCC 2.95.2 but is now a bug in itself.
2144 2003-05-02 Marius Vollmer <mvo@zagadka.de>
2146 * deprecated.h (scm_rstate, scm_rng, SCM_SLOPPY_CONSP,
2147 SCM_SLOPPY_NCONSP, scm_tc7_ssymbol, scm_tc7_msymbol,
2148 scm_tcs_symbols): New.
2150 2003-04-30 Marius Vollmer <marius.vollmer@uni-dortmund.de>

2169 macro was introduced in anticipation of GOOPS method compilation
2172 * goops.c: Removed binding of @dispatch.
2174 2003-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
2176 * eval.c, goops.c (@dispatch, @slot-ref, @slot-set!): Move the
2177 instructions that bind the macros on the scheme level back to
2178 goops.c in order to make sure again that the bindings go into the
2179 (oop goops) module and are not visible from the outside.
2181 2003-04-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
2183 * eval.c: Non functional change: Separated R5RS and non-R5RS
2184 macros into different sections of the file and ordered the
2185 memoizers alphabetically.
2187 2003-04-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
2189 * eval.c (scm_ilookup): Rewritten to improve readability.

2199 * eval.c, eval.h, goops.c, goops.h (scm_m_atslot_ref,
2200 scm_m_atslot_set_x, scm_m_atdispatch): Move the declarations and
2201 definitions of the special goops memoizers from goops.[ch] to
2202 eval.[ch]. Hmm... it seems that scm_m_atdispatch is not used

2226 This set of patches contains no functional changes, only debatable
2227 minor stylistic ones. Still, in order to prepare a patch between
2228 my local copy and the CVS version, I decided to submit the changes
2229 below. Then, the patch will hopefully only contain relevant
2232 * eval.c (iqq): Added const specifier.
2234 * eval.c (scm_trampoline_0, scm_trampoline_1, scm_trampoline_2):
2235 Use NULL instead of 0 to indicate that a pointer is returned.
2236 Removed some misleading 'fall through' comments.

2245 SCM_EXIT_FRAME_HDLR): Use SCM_PACK to convert data to a SCM value
2246 rather than casting to SCM.
2248 2003-04-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
2250 * sort.c, pairs.h: Removed unnecessary includes.
2252 2003-04-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
2254 * sort.c: Replaced hand-made trampline code by the new official
2255 mechanism from eval.c. This fixes a segfault in the new test file
2258 (quicksort, compare_function, scm_restricted_vector_sort_x,
2259 scm_sorted_p, scm_merge, scm_merge_list_x, scm_merge_x,
2260 scm_merge_list_step, scm_sort_x, scm_sort, scm_merge_vector_x,
2261 scm_merge_vector_step, scm_stable_sort_x, scm_stable_sort,
2262 scm_sort_list_x, scm_sort_list): Use trampoline mechanism from

2266 cmp_fun_t): Removed.
2268 (compare_function): Added.
2270 * sort.c (quicksort, SWAP, stack_node): Replaced pointer
2271 arithmetics with index arithmetics. Changed quicksort to work on
2272 an array of SCM values instead of an array of characters. Avoid
2273 bytewise copying of SCM elements. Avoid allocating memory on the
2274 stack with alloca. Fixed some comments.
2276 2003-04-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2278 * eval.c (EXTEND_ENV): Eliminated.
2280 (unmemocopy, SCM_CEVAL, SCM_APPLY): Use SCM_EXTEND_ENV instead of

2288 compiling with SCM_DEBUG==1 by moving definition behind prototype.
2290 * gc.card.c (scm_dbg_t_list_cell, scm_dbg_t_double_cell,
2291 scm_dbg_gc_marked_p, scm_dbg_gc_get_card, scm_dbg_gc_get_bvec,

2293 scm_gc_marked_p, scm_gc_get_card, scm_gc_get_bvec): Fixed
2294 functions such that they check if the object is a non-immediate.
2295 Further, renamed identifiers to use the scm_dbg_ prefix and made
2296 their inclusion into the lib dependent of the
2297 SCM_DEBUG_DEBUGGER_SUPPORT compile time option.
2299 2003-04-21 Dirk Herrmann <D.Herrmann@tu-bs.de>

2304 2003-04-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2306 * list.c (scm_ilength, scm_last_pair), unif.c (l2ra): Prefer
2307 !SCM_CONSP over SCM_NCONSP. Now, guile itself does not include
2308 any calls to SCM_NCONSP any more.
2310 * unif.c (l2ra): Eliminate redundant check.
2312 2003-04-21 Dirk Herrmann <D.Herrmann@tu-bs.de>

2332 * eval.c, eval.h, evalext.c, evalext.h (scm_sym_setter,
2333 scm_m_generalized_set_x, scm_init_evalext): Move the declaration
2334 and definition of the memoizer for the generalized set! macro from
2335 evalext.[ch] to eval.[ch]. Use the SCM_SYNTAX snarfer macro to
2336 define the macro object.
2338 * eval.c, eval.h (s_set_x, scm_s_set_x, scm_m_set_x,
2339 scm_m_generalized_set_x): Since now scm_s_set_x is only used in
2340 eval.c, it is made static and renamed to s_set_x.

2349 to undefineds and registered the object as a permanent object.
2351 * eval.c, eval.h (scm_f_apply, scm_init_eval): Made scm_f_apply
2352 static in eval.c, renamed it to f_apply and registered the object
2353 as a permanent object.
2355 2003-04-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2357 * eval.c (SCM_BIT7, SCM_BIT8, unmemocopy, SCM_CEVAL): Renamed
2358 file-local macro SCM_BIT8 to SCM_BIT7, which is more appropriate.
2360 2003-04-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2362 * numbers.c (scm_logtest): Fixed argument bug in the call to
2363 mpz_and, which showed up when compiling with SCM_DEBUG defined.

2418 * tags.h: scm_t_intptr should have been intptr_t.
2420 2003-04-13 Rob Browning <rlb@defaultvalue.org>
2422 * __scm.h (SCM_FLUSH_REGISTER_WINDOWS): don't just rely on "sparc"
2424 #if defined (sparc) || defined (__sparc__) || defined (__sparc)
2425 as gc_os_dep.c suggests is appropriate.
2427 * goops.c (prep_hashsets): make static to match prototype.
2428 (scm_sym_args): SCM_SYMBOL -> SCM_GLOBAL_SYMBOL. Thanks to Albert
2431 * c-tokenize.lex: remove trailing comma from enum. Thanks to

2464 * init.c: #include gmp.h.
2466 * numbers.h: remove the gmp.h #include (not needed now).
2468 * posix.h: change occurences of "id" to something else so we don't
2469 cause trouble when included via objective-c (can't hurt, might
2470 help). Still have usage in debug.h, though.
2472 2003-04-06 Mikael Djurfeldt <djurfeldt@nada.kth.se>
2474 * random.c (scm_c_random_bignum): Don't generate a random number

2476 generate numbers in the range 0 <= r < m.
2477 (scm_c_default_rstate): Use SCM_VARIABLE_REF to access
2478 scm_var_random_state.
2480 * num2integral.i.c (INTEGRAL2BIG): Put negation of n inside then

2960 decide what to output. See gen-scmconfig.c for details.
2961 (noinst_PROGRAMS): add gen-scmconfig.
2962 (gen_scmconfig_SOURCES): new variable.

3008 generic if not enabled.
3009 (scm_sys_goops_loaded): Setup unextended primitive generics.
3011 * goops.c, goops.h (scm_c_extend_primitive_generic): New function.
3013 * snarf.h (SCM_PRIMITIVE_GENERIC, SCM_PRIMITIVE_GENERIC_1): New
3016 * numbers.c (scm_abs): Use SCM_PRIMITIVE_GENERIC. (This is only a
3017 testing example. All uses of SCM_GPROC should be converted.)
3019 * procprop.c (scm_stand_in_scm_proc): Use scm_assq instead of
3022 * eq.c (scm_equal_p): Turned into a primitive generic.
3024 2003-02-27 Rob Browning <rlb@defaultvalue.org>
3026 * Makefile.am (scmconfig.h): new target -- generate file from
3028 (modinclude_HEADERS): remove version.h.
3029 (nodist_modinclude_HEADERS): add version.h.
3031 2003-02-24 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3033 This fixes a serious GC bug, introduced during the latest
3034 reorganization of the GC, which disabled freeing of structs and
3037 * struct.c (scm_struct_prehistory): Init scm_i_structs_to_free to
3039 (scm_struct_prehistory): Move scm_free_structs to
3040 scm_before_mark_c_hook.
3042 * gc-card.c (sweep_card): Check that we haven't swept structs on
3043 this card before. That can happen if scm_i_sweep_all_segments has
3044 been called from some other place than scm_igc.
3046 2003-02-19 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3048 * environments.c (DEFAULT_OBARRAY_SIZE): Changed from 137 to 31
3049 (since hash tables now adapt their size).
3051 * modules.c (scm_modules_prehistory): Changed from 2001 to 1533
3052 (current number of prehistory bindings; hashtable code will select
3053 a prime which is greater than this value).
3055 * symbols.c (scm_symbols_prehistory): Changed from 1009 to 2139
3056 (current number of initial symbols).

3066 * hooks.c (scm_c_hook_add): Fixed bug in append mode.
3068 The following changes introduce the use of resizable hash tables
3069 throughout Guile. It also renames the old *-hash-table* functions
3070 to *-alist-vector* and places them, together with the rest of the
3071 weak vector support, in the module (ice-9 weak-vector). We should
3072 probably introduce a new, better, API for weak references, for
3073 example "weak pairs" a la MIT-Scheme. (In Chez scheme, they even
3074 look like and are used like ordinary pairs.)
3076 * environments.c (obarray_enter, obarray_retrieve, obarray_remove,
3077 leaf_environment_fold, obarray_remove_all): Use hashtable

3092 (scm_vector_to_hash_table, scm_c_make_resizing_hash_table):
3094 (scm_make_weak_key_hash_table, scm_make_weak_value_hash_table,
3095 scm_make_doubly_weak_hash_table): Moved here from weaks.c.
3097 * init.c (scm_init_guile_1): Removed call to scm_init_weaks; Added
3098 calls to scm_storage_prehistory and scm_hashtab_prehistory.
3100 * modules.c (module-reverse-lookup): Use hashtable accessors.
3102 * symbols.c, symbols.h (scm_i_hash_symbol): New function.
3104 * weaks.c, weaks.h (scm_make_weak_key_alist_vector,
3105 scm_make_weak_value_alist_vector,
3106 scm_make_doubly_weak_alist_vector): New functions.
3108 * weaks.c (scm_init_weaks_builtins): New function.
3110 * weaks.h (SCM_WVECTF_WEAK_KEY, SCM_WVECTF_WEAK_VALUE,
3111 SCM_WVECTF_NOSCAN, SCM_WVECT_WEAK_KEY_P, SCM_WVECT_WEAK_VALUE_P,
3112 SCM_WVECT_NOSCAN_P): New macros.
3114 * weaks.c (scm_scan_weak_vectors): Use SCM_WVECT_WEAK_KEY_P
3115 and SCM_WVECT_WEAK_VALUE_P.
3117 * weaks.c, weaks.h (scm_i_allocate_weak_vector): Renamed from
3118 allocate_weak_vector and exported.
3120 2003-02-13 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3122 * hashtab.c: Undid thread safety. (We decided that it's better to
3123 let the user explicitly protect the tables (or not) according what
3124 is suitable for the application.)
3126 2003-02-12 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3128 * hashtab.c (scm_hash_fn_remove_x, scm_internal_hash_fold): Made
3129 thread safe and handle resizing tables.
3130 (scm_ihashx, scm_sloppy_assx, scm_delx_x): Removed
3131 SCM_DEFER/ALLOW_INTS.
3133 2003-02-11 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3135 * hashtab.c (scm_vector_to_hash_table,
3136 scm_c_make_resizing_hash_table, scm_make_hash_table): New
3138 (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x): Made thread
3139 safe and handle resizing tables.
3141 * weaks.c (scm_make_weak_key_hash_table,
3142 scm_make_weak_value_hash_table, scm_make_doubly_weak_hash_table):
3143 Size argument made optional. Return resizable table if not
3146 2003-02-10 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3148 * eval.c (scm_trampoline_0, scm_trampoline_1, scm_trampoline_2):
3149 Fixed formals tests for closures. (Thanks to Kevin Ryde.)
3151 2003-02-05 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3153 * debug.c (scm_procedure_source): Handle all objects for which
3154 procedure? is #t. (Thanks to Bill Schottstaedt.)
3156 2003-01-23 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3158 * futures.c (mark_futures): Don't need to mark data of recycled
3160 (scan_futures, cleanup_undead): Be smarter about marking
3161 futures---avoid unnecessary passes through future lists.
3163 * futures.h, futures.c: New files; Introduced recycling of
3164 futures. For fine-grained threading this lifts performance to
3165 another level. We can now use parallelization in inner loops of
3166 Guile programs without impossible overhead.
3168 * threads.h, threads.c: Moved futures to their own file.
3170 * Makefile.am (libguile_la_SOURCES): Added futures.c.
3171 (DOT_X_FILES): Added futures.x.
3172 (DOT_DOC_FILES): Added futures.doc.

3176 create_thread and made global.
3178 * futures.c (scm_make_future): New procedure.
3180 * eval.c: #include "libguile/futures.h".
3182 * init.c: #include "futures.h"
3183 (scm_init_guile_1): Call scm_init_futures.
3185 * stime.c (SCM_TIME_UNITS_PER_SECOND): Renamed from CLKTCK.
3187 * stime.h (SCM_TIME_UNITS_PER_SECOND): Definition moved here.
3189 * eval.c, eval.h (scm_trampoline_0, scm_i_call_closure_0): New
3192 * eval.c (scm_trampoline_1): Fixed arguments test for closures.
3194 2003-01-22 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3196 * threads.c (create_thread): Don't unwind dynwind chain of parent
3197 thread before creation. Just start the new thread with an empty
3200 2003-01-20 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3202 * evalext.c, evalext.h (scm_self_evaluating_p): New function.
3204 2003-01-10 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3206 * threads.c (scm_timed_wait_condition_variable): Support timed
3207 waiting also for simple condition variables.
3209 * goops.c (TEST_CHANGE_CLASS): Use scm_change_object_class instead
3210 of calling the procedure change-object-class.
3212 2003-01-09 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3214 * ramap.c (scm_ramapc): Typo in error message.
3216 2003-01-08 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3218 * goops.c (scm_sys_prep_layout_x): Bugfix: Only create layout for
3219 slots with instance allocation.
3221 * goops.c, goops.h (scm_class_extended_generic_with_setter): New
3223 (scm_compute_applicable_methods): Use scm_generic_function_methods.
3225 * goops.c (scm_generic_function_methods): Support extended
3228 2002-12-29 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3230 * eval.c (unmemocopy): Bugfix: scm_sym_delay --> scm_sym_future.
3231 Thanks to Neil for pointing this out!
3233 2002-12-29 Neil Jerram <neil@ossau.uklinux.net>
3235 * lang.h: Remove declarations matching definitions removed from
3236 lang.c (just below).
3238 2002-12-28 Neil Jerram <neil@ossau.uklinux.net>
3240 * lang.c (scm_nil_cons, scm_nil_car, scm_nil_cdr, scm_null,
3241 scm_m_while, scm_nil_eq): Remove definitions that were superfluous
3242 and already commented out.
3244 * read.h (scm_lreadparen), read.c (scm_lreadr, scm_read_token,
3245 scm_lreadparen): Support reading vectors with Elisp syntax if
3246 SCM_ELISP_READ_EXTENSIONS is defined. (SCM_ELISP_READ_EXTENSIONS
3247 is not currently defined, and there isn't even a configure switch
3250 2002-12-26 Marius Vollmer <mvo@zagadka.ping.de>
3252 * Makefile.am (c-tokenize.o): Refer to source via $< so that vpath
3254 (EXTRA_DIST): Added version.h.in.
3256 2002-12-21 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3258 This change makes it possible for one thread to do lazy sweeping
3259 while other threads are running. Now only the mark phase need to
3260 have all threads asleep. We should look further into this issue.
3261 Presently, I've put the locking of scm_i_sweep_mutex at
3262 "conservative" places due to my current lack of knowledge about
3263 the garbage collector. Please feel free to restrict these regions
3264 further to allow for maximal parallelism!
3266 * gc.c, gc.h (scm_i_sweep_mutex): New mutex.
3268 * gc.c (scm_gc_for_newcell), gc-malloc.c (scm_realloc,
3269 scm_gc_register_collectable_memory): Substitute locking of
3270 scm_i_sweep_mutex for calls to scm_i_thread_put_to_sleep.
3271 (scm_igc): Lock sweep mutex here instead of in callers; Calls to
3272 scm_i_thread_put_to_sleep/scm_i_thread_wake_up used to demarkate
3273 the single-thread section (which now only contains the mark
3275 (scm_gc): Don't lock sweeo mutex here since scm_igc locks it;
3276 Removed SCM_DEFER/ALLOW_INTS. Simply call scm_igc directly.
3278 * threads.c (gc_section_mutex): Removed.
3280 2002-12-19 Mikael Djurfeldt <mdj@kvast.blakulla.net>
3282 * threads.c (create_thread): Clear parent field in root state in
3283 order not to unnecessarily remember dead threads.
3285 * eval.c (call_subr2o_1, call_lsubr2_2): New functions.
3286 (scm_trampoline_1, scm_trampoline_2): Use them.
3288 2002-12-18 Mikael Djurfeldt <mdj@kvast.blakulla.net>
3290 Partial introduction of real plugin interface.
3292 * Makefile.am (modinclude_HEADERS): Added threads-plugin.h.
3293 (EXTRA_DIST): Added threads-plugin.c.
3295 * threads-plugin.h, threads-plugin.c: New files.
3297 * threads.h: #include "libguile/threads-plugin.h".
3299 * threads.c: #include "libguile/threads-plugin.c".
3301 * pthread-threads.c: Temporarily remove debugging functions.
3303 * threads.c, threads.h (scm_yield): Added back.
3305 2002-12-18 Mikael Djurfeldt <mdj@kvast.blakulla.net>
3307 * threads.c (really_launch): Detach before unlocking
3308 thread_admin_mutex in order not to risk being joined.
3309 (scm_i_thread_put_to_sleep, scm_i_thread_wake_up): Keep
3310 thread_admin_mutex locked during GC.
3312 * pthread-threads.c, pthread-threads.h: Improvements to debugging
3315 2002-12-16 Mikael Djurfeldt <mdj@kvast.blakulla.net>
3317 * pthread-threads.c, pthread-threads.h (SCM_DEBUG_THREADS): Added
3318 support for debugging mutex operations.
3320 * threads.c (scm_thread): Removed filed joining_threads.
3321 (thread_print): Print thread number as well as address of thread
3323 (scm_join_thread): Bugfix.
3324 (scm_lock_mutex, scm_try_mutex, scm_unlock_mutex,
3325 scm_timed_wait_condition_variable, scm_signal_condition_variable,
3326 scm_broadcast_condition_variable): Use the low-level API.
3327 (scm_all_threads): Return copy of thread list (to prevent
3328 unintended destruction).
3329 (scm_threads_prehistory): Initialize heap_mutex of fake thread.
3331 * pthread-threads.c, pthread-threads.h, threads.c: Fixes to
3332 pthread "native" recursive mutex support.
3334 2002-12-15 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3336 * __scm.h (SCM_DEFER_INTS, SCM_ALLOW_INTS): New definitions.
3337 Simply lock a thread C API recursive mutex.
3338 (SCM_NONREC_CRITICAL_SECTION_START,
3339 SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START,
3340 SCM_REC_CRITICAL_SECTION_END): Removed.
3342 * eval.c: Replaced SOURCE_SECTION_START / SOURCE_SECTION_END with
3343 direct calls to scm_rec_mutex_lock / unlock around the three calls
3344 to scm_m_expand_body.
3346 * eval.c, eval.h (promise_free): New function.
3347 (scm_force): Rewritten; Now thread-safe; Removed
3348 SCM_DEFER/ALLOW_INTS.
3350 * pthread-threads.h: Added partially implemented plugin interface
3351 for recursive mutexes. These are, for now, only intended to be
3352 used internally within the Guile implementation.
3354 * pthread-threads.c: New file.
3356 * threads.c: Conditionally #include "pthread-threads.c".
3358 * eval.c, eval.h (scm_makprom, scm_force): Rewritten to be
3361 * snarf.h (SCM_MUTEX, SCM_GLOBAL_MUTEX, SCM_REC_MUTEX,
3362 SCM_GLOBAL_REC_MUTEX): New macros.
3364 * eval.c, threads.c, threads.h, snarf.h: Rewrote critical section
3365 macros---use mutexes instead.
3367 * tags.h (SCM_IM_FUTURE): New tag.
3369 * eval.c (scm_m_future): New primitive macro.
3370 (SCM_CEVAL): Support futures.
3371 (unmemocopy): Support unmemoization of futures.
3373 * print.c (scm_isymnames): Name of future isym.
3375 * version.c: Unmade some changes to my private copy that got
3376 committed by mistake.
3378 2002-12-11 Mikael Djurfeldt <mdj@kvast.blakulla.net>
3380 * gc-malloc.c, gc.h, init.c: Reverted gc-malloc change of
3383 * gc.c (scm_igc): Don't call scm_i_thread_invalidate_freelists.
3385 * gc.c (scm_gc_sweep): Call it here instead, which is a more
3388 * threads.c (create_thread): Remember root object until the handle
3389 of the new thread is on all_threads list.
3391 * root.c (scm_make_root): Moved copying of fluids until after
3392 creation of root handle so that the fluids are GC protected. Also
3393 removed the critical section.
3395 2002-12-10 Mikael Djurfeldt <mdj@kvast.blakulla.net>
3397 * gc-malloc.c, gc.h (scm_gc_malloc_prehistory): New function.
3399 * gc-malloc.c (malloc_mutex): New mutex.
3400 (scm_gc_malloc_prehistory): Initialize it.
3401 (scm_realloc): Serialize call to realloc
3402 (scm_calloc): Same for calloc.
3403 Thanks to Wolfgang Jaehrling!
3404 (Now we have to make sure all calls to malloc/realloc are made
3405 through scm_malloc.)
3407 * init.c (scm_init_guile_1): Call scm_gc_malloc_prehistory.
3409 * threads.c (really_launch): Release heap (to prevent deadlock).
3410 (create_thread): Release heap before locking thread admin mutex.
3412 2002-12-10 Mikael Djurfeldt <mdj@kvast.blakulla.net>
3414 * threads.c (scm_i_thread_invalidate_freelists): New
3417 * gc.c (scm_igc): Call scm_i_thread_invalidate_freelists.
3419 * modules.c (scm_export): Inserted a return statement.
3421 2002-12-10 Han-Wen Nienhuys <hanwen@cs.uu.nl>
3423 * modules.c (scm_export): new function
3425 * gc-card.c: add a note about malloc()/free() overhead.
3427 2002-12-10 Mikael Djurfeldt <mdj@kvast.blakulla.net>
3429 * Makefile.am (c-tokenize.$(OBJEXT)): Don't look for c-tokenize.c
3432 2002-12-10 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3434 These changes remove scm_ints_disabled (which hasn't has any
3435 effect in Guile for quite some time).
3437 * async.c, error.h (scm_ints_disabled): Removed.
3439 * gc.c (scm_gc_for_newcell), init.c (scm_init_guile_1),
3440 root.c (scm_internal_cwdr), gdbint.c (SCM_BEGIN_FOREIGN_BLOCK,
3441 SCM_END_FOREIGN_BLOCK): Don't touch scm_ints_disabled.
3442 (old_ints): Removed.
3444 * __scm.h (SCM_DEFER_INTS, SCM_ALLOW_INTS): Define as a recursive
3446 (SCM_REDEFER_INTS, SCM_ALLOW_INTS): Define as SCM_DEFER_INTS and
3449 2002-12-09 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3451 * threads.c (scm_mutex_lock, scm_cond_wait, scm_cond_timedwait):
3452 Removed accidental #if 0 around these functions.
3454 These changes are the start of support for preemptive
3455 multithreading. Marius and I have agreed that I commit this code
3456 into the repository although it isn't thoroughly tested and surely
3457 introduces many bugs. The bugs should only be exposed when using
3458 threads, though. Signalling and error handling for threads is
3459 very likely broken. Work on making the implementation cleaner and
3460 more efficient is needed.
3462 * __scm.h (SCM_ALLOW_INTS_ONLY): Removed.
3463 (SCM_NONREC_CRITICAL_SECTION_START,
3464 SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START,
3465 SCM_REC_CRITICAL_SECTION_END): New macros.
3466 (SCM_CRITICAL_SECTION_START/END): Defined here.
3468 * eval.c: Insert SOURCE_SECTION_START / SOURCE_SECTION_END around
3469 the three calls to scm_m_expand_body.
3471 * gc.h: #include "libguile/pthread-threads.h";
3472 (SCM_FREELIST_CREATE, SCM_FREELIST_LOC): New macros.
3474 * gc.c (scm_i_freelist, scm_i_freelist2): Defined to be of type
3477 * gc.c, gc-freelist.c, inline.h: Use SCM_FREELIST_LOC for freelist
3480 * gc-freelist.c (scm_gc_init_freelist): Create freelist keys.
3482 * gc-freelist.c, threads.c (really_launch): Use
3483 SCM_FREELIST_CREATE.
3485 * gc-malloc.c (scm_realloc, scm_gc_register_collectable_memory):
3487 * gc.c (scm_i_expensive_validation_check, scm_gc,
3488 scm_gc_for_newcell): Put threads to sleep before doing GC-related
3489 heap administration so that those pieces of code are executed
3490 single-threaded. We might consider rewriting these code sections
3491 in terms of a "call_gc_code_singly_threaded" construct instead of
3492 calling the pair of scm_i_thread_put_to_sleep () and
3493 scm_i_thread_wake_up (). Also, we would want to have as many of
3494 these sections eleminated.
3496 * init.c (scm_init_guile_1): Call scm_threads_prehistory.
3498 * inline.h: #include "libguile/threads.h"
3500 * pthread-threads.h: Macros now conform more closely to the
3501 pthreads interface. Some of them now take a second argument.
3503 * threads.c, threads.h: Many changes.
3505 2002-12-09 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3507 * Makefile.am (version.h): Changed $^ --> $< in rule for
3510 2002-12-08 Rob Browning <rlb@defaultvalue.org>
3512 * version.h.in (SCM_MICRO_VERSION): use @--@ substitution now.
3513 (SCM_MINOR_VERSION): use @--@ substitution now.
3514 (SCM_MICRO_VERSION): use @--@ substitution now.
3515 (scm_effective_version): new function prototype.
3517 * version.c (scm_effective_version): new function, also add
3520 * Makefile.am (schemelibdir): VERSION -> GUILE_EFFECTIVE_VERSION.
3521 (libpath.h): use GUILE_EFFECTIVE_VERSION to compute
3523 (version.h): generate this here rather than configure.in. This
3524 approach tracks source edits better (i.e. more immediately).
3525 Might be worth considering for other .in files too.
3527 2002-12-02 Marius Vollmer <mvo@zagadka.ping.de>
3529 Reorganized thread package selection. A thread package now only
3530 implements a small set of pthread like functions and Guile
3531 implements the rest on top of that. Guile's implementation is
3532 what the "coop-pthreads" package has been previously. Support for
3533 "coop" threads has been removed until I get time to add it again.
3535 * Makefile.am (libguile_la_SOURCES): Removed iselect.c.
3536 (noinst_HEADERS): Removed coop-threads.c, coop-threads.h, coop.c,
3537 null-threads.c, coop-pthreads.c.
3538 (modinclude_HEADERS): Removed coop-defs.h, coop-pthreads.h. Added
3541 * validate.h (SCM_VALIDATE_THREAD): Moved to threads.h.
3543 * threads.h: Do not include "libguile/coop-defs.h". Include
3544 "libguile/pthread-threads.h" for USE_COPT_THREADS. Removed
3545 (previously deprecated) C level thread API prototypes. They are
3546 now in the thread package specific headers, "null-threads.h" and
3547 "pthread-threads.h".
3548 (SCM_VALIDATE_THREAD, SCM_VALIDATE_MUTEX, SCM_VALIDATE_CONDVAR):
3550 (scm_threads_init): Removed.
3551 (SCM_CRITICAL_SECTION_START, SCM_CRITICAL_SECTION_END,
3552 SCM_THREAD_SWITCHING_CODE, scm_i_switch_counter,
3553 SCM_I_THREAD_SWITCH_COUNT): Define here.
3554 (scm_single_thread_p): Removed.
3555 (scm_call_with_new_thread): Take two args directly instead of list
3557 (scm_i_thread_data, scm_i_set_thread_data, SCM_THREAD_LOCAL_DATA,
3558 SCM_SET_THREAD_LOCAL_DATA): Define here.
3560 * threads.c: Merged with "coop-pthreads.c".
3562 * null-threads.h: Implement pthread-like API as a set of macros.
3564 * pthread-threads.h: New, implement pthread-like API by deferring
3567 * init.c (scm_init_guile_1): Do not call scm_init_iselect, which
3568 has been lost in the reorganization.
3570 2002-12-01 Mikael Djurfeldt <mdj@linnaeus>
3572 The following change makes it possible to move procedure
3573 application dispatch outside inner loops. The motivation was
3574 clean implementation of efficient replacements of R5RS primitives
3577 The semantics is clear: scm_trampoline_N returns an optimized
3578 version of scm_call_N (or NULL if the procedure isn't applicable
3581 Applying the optimization to map and for-each increases efficiency
3582 noticeably. For example, (map abs ls) is 8 times faster than
3585 * eval.h (scm_t_trampoline_1, scm_t_trampoline_2): New types.
3587 * eval.c, eval.h (scm_trampoline_1, scm_trampoline_2): New functions.
3589 * eval.c (call_subr2_2, call_lsubr_2, call_closure_2): New functions;
3590 (map, for-each): Handle also application on two args as a special
3591 case; Use trampolines.
3595 * sort.c (scm_cmp_function): Choose subr2less for scm_tc7_subr_2o;
3596 (subr2oless): Removed.
3597 (scm_restricted_vector_sort_x): Use scm_return_first to keep the
3598 vector GC protected.
3600 * eval.c (check_map_args): Use scm_out_of_range_pos instead of
3603 2002-11-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
3605 * evalext.[ch] (scm_m_undefine, undefine): Deprecated.
3607 2002-11-17 Mikael Djurfeldt <mdj@linnaeus>
3609 * debug.c (scm_make_iloc): Added missing "return".
3611 2002-11-17 Marius Vollmer <mvo@zagadka.ping.de>
3613 * strports.c (scm_eval_string_in_module): Validate second arg to
3614 be a module. Thanks to Arno Peters!
3616 2002-11-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
3618 * .cvsignore: remove goops.c
3620 2002-11-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
3622 * modules.c (scm_env_top_level, scm_lookup_closure_module,
3623 module_variable, scm_module_lookup_closure,
3624 scm_module_transformer, scm_sym2var, scm_module_reverse_lookup,
3625 scm_system_module_env_p): Don't compare SCM values with C
3626 operators == or !=. Avoid SCM_IMP predicates. Prefer !SCM_FALSEP
3629 2002-11-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
3631 * eval.h (SCM_MAKE_ILOC): New macro.
3633 * debug.c (scm_make_iloc): Use SCM_MAKE_ILOC instead of computing
3634 the iloc bitpattern here.
3636 2002-11-14 Mikael Djurfeldt <mdj@linnaeus>
3638 * coop-pthreads.c, coop-pthreads.h: scm_internal_select should be
3639 part of the API, otherwise it's difficult to write Guile
3640 extensions using non-blocking I/O => moved #include
3641 "libguile/iselect.h" from coop-pthreads.c --> coop-pthreads.h.
3643 * coop-pthreads.c (scm_unlock_mutex): Changed s_lock_mutex -->
3646 2002-11-10 Marius Vollmer <mvo@zagadka.ping.de>
3648 * __scm.h (USE_THREADS, GUILE_ISELECT): Do not define here. They

4161 * gc-segment.c (scm_i_get_new_heap_segment): remove cluster cruft:
4162 only use SCM_MIN_HEAP_SEG_SIZE.
4164 * ports.c (scm_add_to_port_table): add backwards compatibility
4167 * ports.h: use scm_i_ prefix for port table and port table size.
4169 2002-08-15 Mikael Djurfeldt <mdj@linnaeus>
4171 * vports.c (scm_make_soft_port): Initialize pt variable.
4173 2002-08-13 Marius Vollmer <mvo@zagadka.ping.de>
4175 * strports.h (scm_c_eval_string_in_module,
4176 scm_eval_string_in_module): New prototypes.
4177 * strports.c (scm_eval_string_in_module): New, but use
4178 "eval-string" as the Scheme name and make second parameter
4180 (scm_eval_string): Implement using scm_eval_string_in_module.
4181 (scm_c_eval_string_in_module): New.
4182 Thanks to Ralf Mattes for the suggestion!
4184 2002-08-09 Han-Wen Nienhuys <hanwen@cs.uu.nl>
4186 * gc-card.c ("sweep_card"): remove SCM_MISC_ERROR messages: print
4189 * gc-mark.c ("scm_gc_mark_dependencies"): idem.
4191 * ports.c ("scm_new_port_table_entry"): return a boxed SCM in
4192 stead of scm_t_port*. The function now takes a tag argument.
4194 2002-08-08 Han-Wen Nienhuys <hanwen@cs.uu.nl>
4196 * gc.h: add scm_debug_cells_gc_interval to public interface
4198 * gc-card.c ("sweep_card"): set scm_gc_running while sweeping.
4200 * gc.c (scm_i_expensive_validation_check): separate expensive
4201 validation checks from cheap ones.
4203 2002-08-06 Han-Wen Nienhuys <hanwen@cs.uu.nl>
4205 * read.c (scm_input_error): new function: give meaningful error
4206 messages, and throw read-error
4208 * gc-malloc.c (scm_calloc): add scm_calloc.
4210 2002-08-05 Han-Wen Nienhuys <hanwen@cs.uu.nl>
4212 * tags.h: remove GC bits documentation from the tags table.
4214 * read.c (INPUT_ERROR): Prepare for file:line:column error
4215 messages for errors in scm_lreadr() and friends.
4217 2002-08-04 Han-Wen Nienhuys <hanwen@cs.uu.nl>
4219 * gc-malloc.c (scm_malloc): use scm_realloc() (simplifies
4221 (scm_gc_calloc): new function
4223 2002-08-04 Han-Wen Nienhuys <hanwen@cs.uu.nl>
4225 * ports.c (scm_new_port_table_entry): init port entry to 0
4228 * ports.c (scm_new_port_table_entry): change function from
4229 scm_add_to_port_table. This prevents cells with null-pointers from
4230 being exposed to GC.
4232 * vports.c (scm_make_soft_port) strports.c (scm_mkstrport),
4233 fports.c (scm_fdes_to_port): Use scm_new_port_table_entry().
4235 * gc.c (scm_gc_stats): add cell-yield and malloc-yield statistic
4238 * numbers.c (big2str): return "0" for 0 iso. ""
4240 * gc-segment.c, gc-malloc.c gc-mark.c, gc-freelist.c, gc-card.c,
4241 private-gc.h: new file
4243 * gc.c: completely revised and cleaned up the GC. It now uses lazy
4244 sweeping. More documentation in workbook/newgc.text
4246 2002-07-25 Marius Vollmer <marius.vollmer@uni-dortmund.de>
4248 * random.c (rstate_free): Return zero.
4250 2002-07-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
4252 * environments.c (remove_key_from_alist): Removed.
4254 (obarray_remove): Simplified.
4256 2002-07-24 Stefan Jahn <stefan@lkcc.org>
4258 * continuations.h: ia64: Include <signal.h> before
4261 2002-07-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
4263 * modules.c (scm_sym2var): Don't compare SCM values with ==.
4265 2002-07-21 Han-Wen Nienhuys <hanwen@cs.uu.nl>
4267 * goops.c (scm_compute_applicable_methods): use
4268 scm_remember_upto_here_1 iso scm_remember_upto_here
4270 * macros.c: include deprecation.h
4272 * vectors.c (scm_vector_move_right_x): remove side effect in
4274 (scm_vector_move_left_x): idem.
4276 * net_db.c, posix.c, socket.c: variable naming: change ans to
4279 * sort.c (scm_merge_vector_x): accept vector as argument
4280 iso. SCM*. This is needed for full GC correctness.
4282 * gc.h: undo previous undocumented changes related to #ifdef
4285 2002-07-20 Han-Wen Nienhuys <hanwen@cs.uu.nl>
4287 * *.c: add space after commas everywhere.
4289 * *.c: use SCM_VECTOR_SET everywhere, where a vector is written.
4290 Document cases where SCM_WRITABLE_VELTS() is used.
4292 * vectors.h (SCM_VELTS): prepare for write barrier, and let
4293 SCM_VELTS() return a const pointer
4294 (SCM_VECTOR_SET): add macro.
4296 2002-07-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
4298 * eval.c (SCM_CEVAL), macros.c (macro_print, scm_makmacro,
4299 scm_sym_macro, scm_macro_type), macros.h (scm_makmacro):
4300 Deprecated the special kind of built-in dynamic syntax transformer
4301 that was inaccurately named "macro". Note: The built-in syntax
4302 transformers that are named "mmacro" or "memoizing-macro" still
4303 exist, and it is these which come much closer to what one would
4306 2002-07-13 Neil Jerram <neil@ossau.uklinux.net>
4308 * eval.c (unmemocopy): Fix for
4309 1001-local-eval-error-backtrace-segfaults (unmemoization crash
4310 with internal definitions and local-eval).
4312 2002-07-12 Gary Houston <ghouston@arglist.com>
4314 * dynl.c: Don't define stub procedures if DYNAMIC_LINKING is not
4315 defined. They don't do anything useful, especially since the
4316 only case where DYNAMIC_LINKING is undefined seems to be
4317 when --with-modules=no is given to configure, which is basically
4318 requesting that the "dynamic linking module" be omitted.
4320 * Makefile.am (libguile_la_SOURCES): move dynl.c from
4321 libguile_la_SOURCES to EXTRA_libguile_la_SOURCES.
4323 * extensions.c (load_extension): check DYNAMIC_LINKING for
4325 * init.c (scm_init_guile_1): check DYNAMIC_LINKING for
4326 scm_init_dynamic_linking.
4328 2002-07-10 Marius Vollmer <mvo@zagadka.ping.de>
4330 * guile.c, iselect.h, net_db.c, posix.c, socket.c: No need to
4331 check for Cygwin when including <winsock2.h>, this is already
4332 check for by configure. Thus, revert change from 2002-07-07.
4334 2002-07-10 Gary Houston <ghouston@arglist.com>
4336 * eq.c: include <string.h>
4337 * dynl.c: docstring editing.
4339 2002-07-09 Gary Houston <ghouston@arglist.com>
4341 * dynl.c (scm_dynamic_call): docstring editing.
4343 2002-07-08 Rob Browning <rlb@defaultvalue.org>
4345 * gc_os_dep.c: HURD fixes.
4347 2002-07-07 Marius Vollmer <mvo@zagadka.ping.de>
4349 Crosscompiling and Cygwin fixes by Jan Nieuwenhuizen. Thanks!
4351 * Makefile.am: Override default rule for c-tokenize.$(OBJECT);
4352 this should be compiled for BUILD host.
4353 Override default rule for
4354 guile_filter_doc_snarfage$(EEXECT); this should run on BUILD host.
4355 Add missing $(EXEEXT) to guile_filter_doc_snarfage invocation.
4356 (snarf2checkedtexi): Use GUILE_FOR_BUILD instead of preinstguile.
4358 * guile.c, iselect.h, net_db.c, posix.c, socket.c: Do not include
4359 <winsock2.h> on Cygwin even when we have it.
4361 2002-07-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
4363 * __scm.h (SCM_CAUTIOUS), eval.c (scm_eval_args, deval_args,
4364 SCM_CEVAL): Removed compile time option SCM_CAUTIOUS to clean up
4365 the code. Full number of arguments checking of closures is
4366 mandatory now. However, the option to disable the checking has
4367 most probably not been used anyway.
4369 2002-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
4371 * __scm.h (SCM_RECKLESS), backtrace.c (SCM_ASSERT), debug.c
4372 (scm_debug_options), eval.c (scm_lookupcar, scm_lookupcar1,
4373 scm_badargsp, SCM_CEVAL, SCM_APPLY, scm_map, scm_for_each),
4374 feature.c (scm_init_feature), gsubr.c (scm_gsubr_apply), numbers.c
4375 (scm_logand, scm_logior, scm_logxor, scm_i_dbl2big), srcprop.c
4376 (scm_source_properties, scm_set_source_properties_x,
4377 scm_source_property): Removed compile time option SCM_RECKLESS to
4378 clean up the code. Full number of arguments checking of closures
4379 is mandatory now. However, the option to disable the checking has
4380 most probably not been used anyway.
4382 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
4383 scm_source_property): Use !SCM_CONSP instead of SCM_NCONSP.
4385 2002-06-30 Gary Houston <ghouston@arglist.com>
4387 * dynl.c: Removed all SCM_DEFER_INTS/SCM_ALLOW_INTS, which won't
4388 do anything useful. Added a comment about need for a mutex if
4389 pre-emptive threading is supported.
4391 * posix.c (scm_convert_exec_args), dynl.c
4392 (scm_make_argv_from_stringlist): static procs: 1) renamed both to
4393 allocate_string_pointers. 2) simplified: don't reallocate the
4394 strings, just make an array of pointers 3) avoid memory leaks on
4395 error 4) let the procedure report errors in its own name.
4396 Consequences: 1) the procedures now assume that SCM strings are
4397 nul-terminated, which should always be the case. 2) Since strings
4398 are not reallocated, it's now possible for strings passed to
4399 dynamic-args-call to be mutated.
4401 2002-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
4403 * __scm.h, eval.c, eval.h: Removed compile time option
4404 MEMOIZE_LOCALS to clean up the code. Now, caching of local
4405 variable positions during memoization is mandatory. However, the
4406 option to disable the caching has most probably not been used
4409 2002-06-18 Marius Vollmer <mvo@zagadka.ping.de>
4411 * print.c (scm_simple_format): Print missing part of format before
4412 ~% control. Thanks to Daniel Skarda!
4414 2002-06-01 Marius Vollmer <mvo@zagadka.ping.de>
4416 * mkstemp.c: Added exception notice to license statement.
4418 2002-05-22 Marius Vollmer <mvo@zagadka.ping.de>
4420 * numbers.c (mem2ureal): When returning an inexact zero, make sure
4421 it is represented as a floating point value so that we can change
4424 From John W. Eaton <jwe@bevo.che.wisc.edu>
4426 * numbers.c (idbl2str): Don't omit sign when printing negative zero.
4428 2002-05-14 Thien-Thi Nguyen <ttn@giblet.glug.org>
4430 * gc_os_dep.c: For I386/OPENBSD, allow for `__i386__'
4431 in addition to `i386'. Thanks to Dale P. Smith.
4433 2002-05-08 Marius Vollmer <mvo@zagadka.ping.de>
4435 * eq.c (real_eqv): New.
4436 (scm_eqv_p): Use it when comparing reals and complexes.
4438 * numbers.c: Include <string.h>, for strncmp.
4439 (mem2complex): Do not create negative NaNs.
4440 (scm_leq_p, scm_geq_p): Explicitely return #f when comparing a
4442 (scm_inexact_to_exact): Signal error when converting a NaN.
4444 2002-05-06 Marius Vollmer <mvo@zagadka.ping.de>
4446 * posix.c (scm_putenv): Handle removing variables explicitely by
4451 * numbers.h: Conditionally include floatingpoint.h, ieeefp.h, and
4452 nan.h. Provide declarations for scm_inf_p, scm_nan_p, scn_inf,
4454 * numbers.c: [SCO && ! HAVE_ISNAN] (isnan): New function.
4455 [SCO && ! HAVE_ISINF] (isinf): New function.
4456 (xisinf, xisnan): New functions.
4458 (isfinite): Define in terms of xisinf.
4459 (scm_inf_p, scm_nan_p): New functions.
4460 (guile_Inf, guile_NaN): New file-scope vars.
4461 (guile_ieee_init): New function.
4462 (scm_inf, scm_nan): New functions.
4463 (idbl2str): Handle Inf and NaN. Remove funny label and
4464 corresponding gotos.
4465 (ALLOW_DIVIDE_BY_ZERO): New macro.
4466 (scm_divide): Allow division by zero to occur if
4467 ALLOW_DIVIDE_BY_ZERO is defined.
4468 Handle bignums and ints as special cases.
4470 Additional stuff by me:
4472 numbers.c (mem2ureal): Recognize "inf.0" and "nan.xxx".
4473 (scm_even_p, scm_odd_p): Treat infinity as even and odd.
4474 (iflo2str): Don't output a '+' for negative numbers or for Inf and
4475 NaN. They will provide their own sign.
4476 (scm_divide): Only allow divides by inexact zeros. Dividing by
4477 exact zeros still signals an errors.
4479 2002-04-22 Thien-Thi Nguyen <ttn@giblet.glug.org>
4481 * goops.h (scm_slot_exists_p): Rename from scm_slots_exists_p.
4482 * goops.c (scm_slot_exists_p): Rename from scm_slots_exists_p.
4483 (scm_slot_exists_p): Rename from scm_slots_exists_p.
4484 Thanks to Andreas Rottmann.
4486 2002-04-20 Gary Houston <ghouston@arglist.com>
4488 * removal of unused fields in root state (thanks to Christopher
4489 Cramer for pointing out the disuse.)
4490 * root.h (scm_root_state): removed def_inp, def_outp, def_errp.
4491 (scm_def_inp, scm_def_outp, scm_def_errp): removed.
4493 * root.c (root_mark): don't mark them.
4494 (scm_make_root): don't set them to #f.
4495 * init.c (scm_init_standard_ports): don't initialise with the
4498 2002-04-17 Marius Vollmer <mvo@zagadka.ping.de>
4500 * Makefile.am (EXTRA_DIST): Added cpp_err_symbols.c and
4503 2002-04-16 Marius Vollmer <mvo@zagadka.ping.de>
4505 * guile-snarf.in: Do not clean input file. This would write to
4506 the $(srcdir) during a VPATH build, which is not allowed. It also
4507 isn't needed since it only works when an output filename has been
4508 specified and in that case we don't need to clean the input file
4509 because the output file will already exist.
4511 2002-03-31 Marius Vollmer <mvo@zagadka.ping.de>
4513 * guile-snarf: Install the trap for removing $cleanfile only when
4514 the value of $cleanfile is actually known.
4516 2002-04-10 Rob Browning <rlb@defaultvalue.org>
4518 * .cvsignore: add versiondat.h and *.c.clean.c.
4520 2002-03-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
4522 * srcprop.[ch] (scm_c_source_property_breakpoint_p): New
4523 function, replaces macro SRCBRKP.
4525 (SRCBRKP): Deprecated.
4527 * eval.c (SCM_CEVAL): Replaced use of SRCBRKP by call to
4528 scm_c_source_property_breakpoint_p. Removed some use of arg1 as
4531 2002-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
4533 * debug.h, eval.c: Deprecated CHECK_ENTRY, CHECK_APPLY and
4534 CHECK_EXIT and removed all references to them.
4536 2002-03-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
4538 * debug.h (scm_ready_p, debug_print): Removed declarations.
4540 * eval.c (EVALCELLCAR): Removed.
4542 (SCM_CEVAL): Eliminated label loopnoap. Removed side-effecting
4543 operation from condition.
4545 2002-03-24 Marius Vollmer <mvo@zagadka.ping.de>
4547 * guile-snarf.in: When the output filename is "-", write to
4548 stdout. When no "-o" option is given, use "-" as the output
4549 filename (i.e., stdout). Only 'clean' the inputfile or remove the
4550 output file on error when the output file name is not "-". Define
4551 the preprocessor macro SCM_MAGIC_SNARFER while snarfing.
4553 * Makefile.am (.c.x): Pass "-o $@" to guile-snarf.
4555 2002-03-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
4557 * eval.c (SCM_CEVAL, SCM_APPLY): Eliminated labels wrongnumargs
4558 and the corresponding goto statements. Removed redundant code.
4560 2002-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
4562 * eval.c (SCM_CEVAL): Minimized scope of variable arg2.
4563 Eliminated redundant SCM_IMP check. Exlined call to EVALCAR.
4564 Re-enabled handing of rpsubrs and asubrs.
4566 2002-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
4568 * eval.c (SIDEVAL): Removed.
4570 (SCM_CEVAL): Minimized scope of variable orig_sym. Eliminated
4571 goto-labels cdrxnoap, cdrxbegin and nontoplevel_cdrxnoap. Changed
4572 argument checking order for set! to locals, variables and symbols.
4573 Improvements to control structure. Removed some uses of arg1 and
4574 arg2 as temporary variables.
4576 2002-03-15 Thien-Thi Nguyen <ttn@giblet.glug.org>
4578 * guile-snarf.in: Remove "--compat=1.4" support.
4579 Add "-d" and "-D" support.
4581 (deprecated_list): New var.
4582 (compat_mode_clean_xxx): Delete.
4583 (grep_deprecated): New func.
4584 ("main"): If "-d" or "-D", call `grep_deprecated'.
4586 2002-03-15 Neil Jerram <neil@ossau.uklinux.net>
4588 * hooks.h: Change scm_t_c_hookype_t everywhere to
4593 * strings.c (scm_string_p): Change unnecessary `iff' to `if'.
4595 * ports.c (scm_sys_make_void_port): Use `@file'.
4597 * numbers.c (scm_number_p, scm_real_p): Use `otherwise' rather
4600 * macros.c (scm_makmacro): Don't say that the form replaces its
4601 source, because it doesn't.
4602 (scm_makmmacro): Clarify difference between this and scm_makmacro.
4604 * backtrace.c (scm_display_error), filesys.c (scm_umask,
4605 scm_select, scm_basename), goops.c (scm_method_generic_function),
4606 numbers.c (scm_integer_length), posix.c (scm_getgroups, scm_execl,
4607 scm_setlocale, scm_flock), socket.c (scm_shutdown): Correct
4610 * debug.c (scm_debug_options), eval.c
4611 (scm_eval_options_interface), read.c (scm_read_options): Change
4612 incorrect @var in docstring to @code.
4614 2002-03-14 Marius Vollmer <mvo@zagadka.ping.de>
4616 * unif.c (singp): Use SCM_REALP instead of SCM_SLOPPY_REALP.
4618 * snarf.h (SCM_SNARF_INIT): Add "^:^" after code so that
4619 guile-snarf can remove trailing non-init code.
4621 * guile-snarf.in (modern_snarf): Remove everything following and
4622 including "^:^" from the output.
4624 2002-03-14 Dirk Herrmann <D.Herrmann@tu-bs.de>

4632 * guile-snarf.in: Update copyright.
4633 Rewrite to internalize error handling.
4634 Add "--compat=1.4" handling.
4637 * Makefile.am (libpath.h): Use @top_srcdir_absolute@.
4638 (snarfcppopts): New var.
4639 (.c.x): Use $(snarfcppopts). Rework guile-snarf usage.
4640 (.c.doc): Use $(snarfcppopts).
4642 * alist.c, arbiters.c, async.c, backtrace.c, boolean.c, chars.c,
4643 continuations.c, debug-malloc.c, debug.c, deprecation.c, dynl.c,
4644 dynwind.c, environments.c, eq.c, error.c, eval.c, evalext.c,

4654 unif.c, values.c, variable.c, vectors.c, version.c, vports.c,
4655 weaks.c: Retire inclusion guard macro SCM_MAGIC_SNARFER.
4657 2002-03-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
4659 * eval.c (SCM_CEVAL): Got rid of the last reference to t.lloc.
4660 The next step will be to remove the union 't' and simplify the
4661 code of SCM_CEVAL that way.
4663 2002-03-12 Neil Jerram <neil@ossau.uklinux.net>
4665 * iselect.c (collisionp, gnfds, greadfds, gwritefds, gexceptfds,
4666 rreadfds, rwritefds, rexceptfds): Made static.
4668 * gc.c (terminating), fports.c (terminating): Renamed
4671 2002-03-11 Marius Vollmer <mvo@zagadka.ping.de>
4673 * numbers.c (scm_divide): Adapt code from libstdc++/f2c to void
4674 potential overflow problems. Thanks to John W Eaton!
4676 * strop.c (string_capitalize_x): Treat characters as unsigned so
4677 that 8-bit chars work. Thanks to David Pirotte!
4679 2002-03-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
4681 * eval.c (SCM_CEVAL): Cleaned up the handling of 'slot-ref',
4682 'slot-set!' and 'nil-cond'. Removed some uses of t.arg1, arg2 and
4683 proc as temporary variables. Introduced temporary variables with
4684 hopefully descriptive names for clarification. Replaced SCM_N?IMP
4685 by a more explicit predicate in some places.

4692 arg2. Removed some uses of t.arg1, t.lloc and proc as temporary
4693 variables. Introduced temporary variables with hopefully
4694 descriptive names for clarification. Replaced SCM_N?IMP by a more
4695 explicit predicate in some places. Use SCM_INSTANCE_HASH instead
4696 of computing the expression explicitly. Eliminate now unused
4697 label nontoplevel_cdrxbegin.

4715 * debug.h (SCM_MAX_FRAME_SIZE): Remove incorrect comment about use
4716 of SCM_MAX_FRAME_SIZE as a bit mask; it isn't used like this.
4718 * eval.c (SCM_CEVAL): Don't store scm_debug_eframe_size in
4719 debug.status. It isn't needed, and it can overflow the bits
4720 reserved for it (which may lead to a segv or a GC abort).
4722 2002-03-02 Dirk Herrmann <D.Herrmann@tu-bs.de>
4724 * eval.c (SCM_CEVAL): Cleaned up the handling of 'apply'. Removed

4736 * eval.c (SCM_CEVAL): Cleaned up the handling of 'if', 'let',
4737 'letrec' and 'set*': Removed some uses of t.arg1, t.lloc and proc
4738 as temporary variables. Removed side-effecting operations from
4739 conditions and macro calls. Introduced temporary variables with
4740 hopefully descriptive names for clarification. Replaced SCM_N?IMP
4741 by a more explicit predicate in some places. Removed code that
4742 was conditionally compiled if SICP was defined - which it never
4745 2002-03-02 Dirk Herrmann <D.Herrmann@tu-bs.de>
4747 * eval.c (SCM_CEVAL): Cleaned up the handling of 'cons' and 'do':

4750 Introduced temporary variables with hopefully descriptive names
4751 for clarification. Replaced SCM_N?IMP by a more explicit
4752 predicate in some places.

4762 variables. Removed side-effecting operations from conditions and
4763 macro calls. Introduced temporary variables for clarification.
4764 Sorted if-else-if check for the type of the last form in a list by
4765 frequency. Avoided some unnecessary tail-recursion calls.

5186 * numbers.c (scm_divide): Fix more division by zero errors.
5188 2001-11-21 Gary Houston <ghouston@arglist.com>
5190 * Makefile.am (OMIT_DEPENDENCIES): removed, since it seems to be
5191 obsolete. autogen.sh says:
5192 invalid unused variable name: `OMIT_DEPENDENCIES'
5194 2001-11-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
5196 * numbers.c (scm_divide): Fix (/ 0). Thanks to Keith Wright for

5214 M$-Windows compiler. Include some pieces of code (protoent and
5215 servent interface) protected by HAVE_* macros when using a
5216 native M$-Windows compiler.
5218 2001-11-20 Marius Vollmer <mvo@zagadka.ping.de>
5220 * modules.c (scm_c_export): Do nothing when the first argument is
5221 already the terminating NULL. Thanks to Han-Wen Nienhuys!
5223 2001-11-20 Thien-Thi Nguyen <ttn@glug.org>

5240 (SCM_MICRO_VERSION): renamed from SCM_GUILE_MICRO_VERSION.
5242 2001-11-18 Neil Jerram <neil@ossau.uklinux.net>
5244 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
5245 Rewrite docstrings without reference to substring-move-left/right,
5246 since the latter no longer exist.
5248 2001-11-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
5250 * eval.c: Removed bogus comment about acros.
5252 (scm_unmemocar): Use !SCM_CONSP instead of SCM_IMP.
5253 Minimize scope of local variable. Eliminate dependency on
5254 macro DEBUG_EXTENSIONS.
5256 (s_splicing): New error message string.
5258 (scm_m_body): Issue 'bad body' message rather than 'missing
5259 expression' message.
5261 (scm_m_quote): Eliminate unnecessary copying.
5263 (scm_m_lambda, scm_m_letstar, scm_m_letrec, scm_m_let): Leave the
5264 checking of the body to scm_m_body.
5266 (scm_m_do): Move comment to function header. Rename arg1 to
5267 binding. Made the code a bit easier to read.
5271 (iqq): Added a comment. Changed the depth parameter to
5272 unsigned. Use size_t for vector lengths. Make sure vector object
5273 is gc protected as long as its contents are read. Add some syntax
5274 checks. Get rid of unnecessary SCM_IMP test. Clean up the
5275 control structure a bit.
5277 (scm_m_delay): Added comment about the implementation of
5280 (scm_m_define): Add comment about guile's currying define
5281 syntax. Renamed 'proc' to 'name'. Eliminate dependency on macro
5282 DEBUG_EXTENSIONS. Simplified code a bit. Eliminate SICP code.
5284 (scm_m_letrec1): Removed. Part of the functionality is taken
5285 over by the new function 'transform_bindings'.
5287 (transform_bindings): New function. Takes over some of the
5288 functionality of removed function 'scm_m_letrec1', namely to split
5289 a list of bindings into a reversed list of variables and a list of
5292 (scm_m_letrec): Call 'transform_bindings'.
5294 (scm_m_let): Minimized scope of local variables. Renamed 'proc'
5295 to 'temp' and 'arg1' to 'binding'. Eliminated redundant SCM_NIMP
5296 test. Use 'transform_bindings'. Fixed scoping error with named
5297 let (Thanks to Aubrey Jaffer for reporting the bug and to Neil
5298 Jerram for suggesting the fix). Cleaned up the control structure
5301 (scm_m_expand_body): Use 'transform_bindings'. Eliminated
5302 unnecessary consing. Eliminated unnecessary
5303 SCM_DEFER/ALLOW_INTS.
5305 (SCM_CEVAL): Un-obfuscated some loops.
5307 2001-11-16 Neil Jerram <neil@ossau.uklinux.net>
5309 * gc.h (scm_unhash_name): Old declaration removed.
5311 * eval.c (s_scm_eval): Change @var{primitive-eval} to
5312 @code{primitive-eval}.
5314 * feature.c, vectors.c, net_db.c, unif.c, weaks.c, struct.c,
5315 version.c, alist.c, ports.c, ramap.c, unif.c, strings.c, list.c:
5316 Change @deffnx lines in docstrings to say {Scheme Procedure}
5317 rather than primitive or procedure.
5319 * posix.c (scm_execl), filesys.c (scm_close), unif.c
5320 (scm_array_set_x, scm_array_contents, scm_uniform_array_read_x,
5321 scm_bit_set_star_x, scm_bit_invert_x), ramap.c (scm_array_fill_x,
5322 scm_array_for_each, scm_array_index_map_x), vectors.c (scm_vector,
5323 scm_make_vector, scm_vector_to_list, scm_vector_fill_x), strop.c
5324 (scm_string_split, scm_string_ci_to_symbol), strings.c
5325 (scm_string_p), sort.c (scm_merge), print.c (scm_newline),
5326 macros.c (scm_macro_type), alist.c (scm_acons, scm_assq):
5327 Docstring fixes and improvements reflecting edits that have been
5328 made in the reference manual source.
5330 * objprop.c (scm_object_properties, scm_set_object_properties_x,
5331 scm_object_property, scm_set_object_property_x): Remove invalid
5332 @deffnx lines for corresponding procedure property primitives.
5334 These changes add a @deffnx C function declaration and function
5335 index entries for each Guile primitive to the copy of the doc
5336 snarf output that is used for reference manual synchronization.
5337 Online help is unchanged.
5339 * snarf.h (SCM_SNARF_DOCS): Output primitive's C function name.
5340 (SCM_DEFINE, SCM_DEFINE1, SCM_REGISTER_PROC): Supply to C function
5341 name to SCM_SNARF_DOCS.
5343 * guile-snarf-docs-texi.in: Pass the shell script's arguments into
5344 snarf-check-and-output-texi.
5346 * Makefile.am (guile-procedures.texi): New rule.
5347 (BUILT_SOURCES, guile.texi, guile-procedures.txt, CLEANFILES):
5348 Changed so that the last stage of doc snarfing is now performed
5349 twice, once to produce guile-procedures.txt for online help, and
5350 once to produce guile.texi for reference manual synchronization.
5352 2001-11-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
5354 * eval.c (RETURN): Wrap in do{}while(0) in order to make it
5355 safely usable as a single statement followed by a ';', for example
5358 (SCM_CEVAL, SCM_APPLY): Clean up code using 'RETURN'.
5360 2001-11-13 Neil Jerram <neil@ossau.uklinux.net>
5362 * random.c (scm_random_solid_sphere_x,
5363 scm_random_hollow_sphere_x): Correct "shere" typos.
5365 * hashtab.c (scm_hash_fold): Add missing apostrophe to docstring.
5367 * version.c (scm_version): Update docstring to include
5370 2001-11-13 Marius Vollmer <mvo@zagadka.ping.de>

5376 scm_substring_move_right_x): Removed.
5378 * __scm.h (HAVE_UINTPTR_T, HAVE_PTRDIFF_T, HAVE_LONG_LONG,
5379 HAVE_LONG_LONGS): Define to "1" when defining them, to mirror what
5382 2001-11-12 Marius Vollmer <mvo@zagadka.ping.de>
5384 * numbers.c: Document macros to define when including
5385 num2integral.i.c. MAX_VALUE and MIN_VALU are no longer used, we
5386 now rely on SIZEOF_ macros that have been figured out at
5389 * num2integral.i.c: Adapt to new interface.
5390 (NUM2INTEGRAL): Test whether a fixnum can be represented in the
5391 target type by casting it and checking whether it is still the
5392 same. Do not try to handle bignums for integral types that are
5393 smaller than fixnums. When handling bignums, collect the
5394 magnituse first into a unsigned type, and correctly check for
5396 (INTEGRAL2BIG): Do not use MIN_VALUE explicitely by observing that
5397 only -MIN_VALUE can still be negative of all negative numbers (in
5400 * tags.h (SIZEOF_SCM_T_BITS): Define it appropriately.
5402 * __scm.h: Define HAVE_UINTPTR_T, HAVE_PTRDIFF_T and
5403 HAVE_LONG_LONG depending on whether their size is non-zero.
5405 2001-11-11 Thien-Thi Nguyen <ttn@glug.org>
5407 * strop.c (scm_string_null_p): Docfix; nfc.
5408 Thanks to Scott Lenser.
5410 2001-11-07 Neil Jerram <neil@ossau.uklinux.net>

5415 * unif.c (scm_uniform_array_write), ports.c
5416 (scm_current_output_port, scm_force_output), dynwind.c
5417 (scm_dynamic_wind), scmsigs.c (scm_setitimer, scm_getitimer),
5418 filesys.c (scm_open, scm_lstat), struct.c
5419 (scm_make_struct_layout), random.c (scm_random,
5420 scm_random_solid_sphere_x, scm_random_hollow_sphere_x, strop.c
5421 (scm_i_index): Remove superfluous whitespace from end of docstring

5426 scm_make_undefined_variable, scm_variable_p, scm_variable_set_x,
5427 scm_variable_bound_p), scmsigs.c (scm_setitimer, scm_getitimer),
5428 posix.c (scm_crypt), struct.c (scm_make_vtable_vtable), hashtab.c
5429 (scm_hash_fold), ports.c (scm_port_for_each): Remove superfluous
5430 newline at end of docstrings.
5432 * modules.c (scm_set_current_module): Add missing newline to
5435 2001-11-07 Stefan Jahn <stefan@lkcc.org>
5437 * win32-socket.[ch]: New files. Defines Winsock-API error codes
5438 and makes them available through Guile. That is because the
5439 Winsock-API does not store its errors in `errno' and thus cannot
5440 return error messages via `strerror (errno)'.
5442 * socket.c (scm_init_socket): Initialize `win32-socket' part
5443 here under M$-Windows.
5445 * numbers.h: Added missing declaration of
5446 `scm_sys_check_number_conversions()'.
5448 * error.c: Local definition of SCM_I_STRERROR and SCM_I_ERRNO
5449 and use in `(strerror)' and `(system-error)'.
5451 * Makefile.am (EXTRA_libguile_la_SOURCES): Added
5452 `win32-socket.[ch]' to extra source and header files.
5454 2001-11-06 Marius Vollmer <mvo@zagadka.ping.de>
5456 * script.c (scm_shell_usage, scm_compile_shell_switches): Prepend
5457 a call to turn-on-debugging when --debug has been given instead of
5458 turning it on directly. Also, handle new `--no-debug' option,
5459 which might suppress the call to turn-on-debugging.
5461 2001-11-05 Stefan Jahn <stefan@lkcc.org>
5463 * struct.c (s_scm_struct_vtable_p): Corrected docstring.
5465 2001-11-04 Stefan Jahn <stefan@lkcc.org>
5467 * Makefile.am (libguile_la_LIBADD): Added $(THREAD_LIBS_LOCAL)
5468 here (was at guile_LDADD) which describes the dependency
5469 correctly and allows a clean build on Win32.
5471 * __scm.h (SCM_API): Follow-up patch. Renamed __FOO__ macros
5474 * __scm.h: USE_DLL_IMPORT indicates the usage of the DLL
5475 import macros for external libraries (libcrypt, libqthreads,
5476 libreadline and libregex).
5478 * coop-defs.h: Include <winsock2.h> for `struct timeval'.
5480 * posix.c (flock): Added support for flock() in M$-Windows.
5482 * guile.c (SCM_IMPORT): Follow-up patch. Use SCM_IMPORT instead
5485 * fports.c (getflags): Differentiate reading and writing pipes
5488 * filesys.c (S_IS*): Redefine all of the S_IS*() macros for
5491 * coop.c (coop_condition_variable_timed_wait_mutex): Use
5492 conditionalized error code if `ETIMEDOUT' is not available.
5493 (scm_thread_usleep): Remove bogus declaration of `struct timeval
5496 * numbers.c (PTRDIFF_MIN): Moved this definition where it actually
5497 belongs. That is because NO_PREPRO_MAGIC gets undefined after
5498 each inclusion of `num2integral.i.c'.
5499 (SIZE_MAX): Define NO_PREPRO_MAGIC if SIZE_MAX is undefined.
5501 2001-11-03 Marius Vollmer <mvo@zagadka.ping.de>
5503 * eval.c (scm_m_begin): Allow `(begin)`, with no subforms.
5504 (SCM_CEVAL): Evaluate an empty `begin' to SCM_UNSPECIFIED.
5506 2001-11-02 Mikael Djurfeldt <mdj@linnaeus>
5508 * print.c (scm_iprin1): Mark print state as revealed when
5509 dispatching to generic write or display.
5511 * unif.c (scm_ra2contig): Fixed memory overwrite bug.
5513 2001-11-02 Marius Vollmer <mvo@zagadka.ping.de>
5515 Support for native Win32. Thanks to Stefan Jahn!
5517 * Makefile.am: Add win32-uname.c, win32-uname.h, win32-dirent.c
5518 and win32-dirent.h to extra source and header files. These
5519 include the uname() and the POSIX dirent interface implementation
5520 for M$-Windows. Put `-no-undefined' into LDFLAGS to support
5521 linkers which do not allow unresolved symbols inside shared
5522 libraries. Corrected `guile_filter_doc_snarfage$(EXEEXT)'
5525 * __scm.h: Defined SCM_API. This macro gets prepended to all
5526 function and data definitions which should be exported or imported
5527 in the resulting dynamic link library in the Win32 port.
5529 * __scm.h, alist.h, arbiters.h, async.h, backtrace.h, boolean.h,
5530 chars.h, continuations.h, coop-defs.h, coop-threads.h,
5531 debug-malloc.h, debug.h, deprecation.h, dynl.h, dynwind.h,

5542 tags.h, threads.h, throw.h, unif.h, values.h, variable.h, vectors.h,
5544 Prefixed each each exported symbol with SCM_API.
5546 * continuations.c: Added comment about the use of the extern
5547 declarations of {get,set}context() functions used in the ia64 port.
5549 * continuations.h, gc.c: `__libc_ia64_register_backing_store_base'
5550 is meant to be a `unsigned long *'.
5552 * filesys.c: Include `direct.h' if possible. Use local
5553 `win32-dirent.h' for the native M$-Windows port. Define S_IS*()
5554 macros for M$-Windows. Implementation of `fstat_Win32()' which is
5555 able to differentiate between sockets and other file descriptors.
5556 Use this function as wrapper in `scm_fstat()'. Fixed typo in
5559 * fports.c: Include `io.h' is possible. Put `*fp' into referring
5560 statement block in `scm_fport_buffer_add()'.
5561 Some corrections in `getflags()'.
5563 * gdb_interface.h (GDB_INTERFACE): Also support __CYGWIN__.
5565 * guile.c: Make sure to define __SCM_IMPORT__ for shared library
5566 build on Win32. Disable preloaded symbols on Win2 platforms.
5568 * ioext.c, ports.c: Include `io.h' is possible.
5570 * mkstemp.c: Include `process.h' is possible.
5572 * net_db.c: Disable extern declaration of `h_errno' for __CYGWIN__,
5574 Put `scm_return_entry()' into HAVE_GETSERVENT conditional.
5576 * posix.c: Remove unnecessary dirent includes and defines. Include
5577 local `win32-uname.h' for MinGW. Extern declaration of
5578 `mkstemp()' for systems where it does not exists. Make
5579 `getlogin()' available on M$-Windows.
5581 * scmsigs.c: Made `usleep()' avalable on MinGW.
5583 * stime.c: On M$-Windows `tzname[]' is known to be `_tzname[]'.
5585 * win32-dirent.c: Include "win32-dirent.h", not "dirent.h".
5587 * win32-uname.c: Include "win32-uname.h", not "uname.h".
5589 2001-10-28 Mikael Djurfeldt <mdj@linnaeus>
5591 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write):
5592 Don't apply scm_uniform_vector_length on arrays.
5594 2001-10-14 Dirk Herrmann <D.Herrmann@tu-bs.de>
5596 * eval.c (scm_lookupcar, scm_m_letstar, scm_m_do, iqq,
5597 scm_m_define, scm_m_letrec1, scm_m_let, scm_m_expand_body,
5598 scm_macroexp, unmemocopy, scm_eval_args, scm_deval_args,
5599 SCM_CEVAL, scm_map, scm_init_eval): When building lists, prefer
5600 scm_list_<n> over scm_cons[2]?.
5602 (scm_unmemocar, scm_m_cond, scm_m_letstar, scm_m_letrec1,
5603 scm_m_let, scm_m_atbind, unmemocopy, SCM_CEVAL, SCM_APPLY): Use
5604 SCM_C[AD][AD]R instead of explicit form.
5606 (scm_m_set_x, scm_m_cond, scm_m_letstar, scm_m_do): Reordered
5607 comparison parameters.
5609 (scm_m_case, scm_m_cond, scm_m_letstar, scm_m_do, SCM_CEVAL): Use
5610 !SCM_NULLP instead of SCM_NIMP.
5612 (scm_m_case): Don't copy the form. Renamed proc to clause and
5613 minimized its scope. Renamed x to clauses. Removed side
5614 effecting operation from macro call.
5616 (scm_m_cond): Don't copy the form. Renamed arg1 to clause and
5617 minimized its scope. Renamed x to clauses. Minimized the scope
5618 of variable 'len'. Make sure the else clause is treated specially
5619 even in case of '=>' occurences. Don't change the else to #t in
5620 order to be able to distinguish this case in the evaluator. Leave
5621 type checking of the recipient to the evaluator.
5623 (scm_c_improper_memq): Made the comment somewhat clearer.
5625 (scm_m_lambda): Renamed proc to formals. Removed unnecessary
5626 test for SCM_IM_LET at the place of the formal parameters.
5627 Simplified the formal parameter checking.
5629 (scm_m_letstar): Added Comment. Renamed proc to bindings.
5630 Renamed arg1 to binding and minimized its scope. Eliminated
5631 unnecessary consing.
5633 (scm_m_do): Renamed proc to bindings. Minimized the scope of
5636 (build_binding_list): New static function.
5638 (unmemocopy): Don't use SCM_TYP7 on pairs (it's unclean).
5639 Further, split up the 'letrec' unmemoizing code to the
5640 corresponding parts for 'do', 'let' and 'letrec', adding comments
5641 to each form. Cleanup the handling of the do form (This removes
5642 some *real* code :-).
5644 (SCM_CEVAL): Removed side effecting operation from macro call.
5645 Handle the 'else clause of the 'cond form specially - the symbol
5646 'else is not replaced with #t any more.
5648 2001-10-14 Gary Houston <ghouston@arglist.com>
5650 * version.c (scm_version): use sprintf instead of snprintf,
5651 for portability. thanks to Bill Schottstaedt.
5653 2001-10-14 Mikael Djurfeldt <mdj@linnaeus>
5655 * read.c (scm_lreadr): When user-defined hash procedure returns
5656 SCM_UNSPECIFIED: Fall back to standard handling instead of raising
5657 an exception. (This prevents parsing of uniform vectors from
5658 interfering with parsing of numbers.)
5660 2001-10-13 Marius Vollmer <mvo@zagadka.ping.de>
5662 * numbers.c: Set NO_PREPRO_MAGIC when defining our version of
5663 PTRDIFF_MIN. Thanks to Ken Raeburn.
5665 2001-10-07 Marius Vollmer <mvo@zagadka.ping.de>
5667 * Makefile.am (EXTRA_libguile_la_SOURCES): Added "mkstemp.c".
5669 * eval.c (scm_m_atbind): First try to find the variable without
5670 defining it locally; when it has not been found, define it
5673 * modules.c (module_variable): Pass over variables that exist but
5676 2001-10-06 Marius Vollmer <mvo@zagadka.ping.de>
5678 * backtrace.c (display_backtrace_file_and_line): Only use
5679 scm_basename when POSIX support is compiled in. Thanks to Chris
5682 2001-10-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
5684 * numbers.c (mem2uinteger): Return number read so far when coming
5685 across a hexdigit after having read a # or if not reading a hex
5686 value. This will enable the calling code to correctly handle
5687 forms like 1e2. (The background is, that the exponent markers d,
5688 e and f are also hexdigits.) Thanks to Mikael Djurfeldt for
5689 providing this patch.
5691 (mem2complex): Fix erroneous double-negation. Now, numbers like
5692 1-i will be read correctly.
5694 2001-10-12 Mikael Djurfeldt <mdj@linnaeus>
5696 * debug.c (scm_mem_to_proc): Fixed typo in previous change.
5698 * validate.h (SCM_VALIDATE_DOUBLE_DEF_COPY): New macro.
5700 2001-10-12 Dirk Herrmann <D.Herrmann@tu-bs.de>
5702 * print.c (scm_print_state_vtable, print_state_pool):
5703 Initialize. These variables are now registered as gc roots.
5705 (scm_current_pstate): Update documentation.
5707 (scm_current_pstate, scm_make_print_state, scm_free_print_state,
5708 scm_prin1, scm_init_print): print_state_pool is registered as a
5709 gc root and thus does not need to be protected by a surrounding
5712 (make_print_state): The car of print_state_pool no longer holds
5713 the scm_print_state_vtable.
5715 (scm_current_pstate, scm_make_print_state, print_circref,
5716 scm_iprin1, scm_prin1, scm_iprlist): Prefer !SCM_<foo> over
5719 (scm_prin1): When building lists, prefer scm_list_<n> over
5722 (scm_iprlist): Removed a redundant SCM_IMP test.
5724 (scm_simple_format): Use SCM_EQ_P to compare SCM values.
5726 2001-10-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
5728 * debug.c (scm_make_iloc): Prefer !SCM_<foo> over SCM_N<foo>.
5730 (scm_memcons, scm_mem_to_proc): When building lists, prefer
5731 scm_list_<n> over scm_cons[2]?.
5733 (scm_mem_to_proc): Prefer SCM_CONSP over SCM_NIMP.
5735 (scm_procedure_name): Use SCM_CADR instead of explicit form.
5737 (debugobj_print): Coerce scm_intprint arg 1 to long, not int.
5738 Thanks to Rob Browning for the patch (see log entry 2001-09-21) -
5739 for some reason his patch didn't make it into the cvs.
5741 2001-10-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
5743 * numbers.c (mem2decimal_from_point): Cleaned up the parsing a
5744 little bit - should even be somewhat more accurate now.
5746 2001-10-08 Rob Browning <rlb@defaultvalue.org>
5748 * gc.c: support ia64 register backing store.
5749 (SCM_MARK_BACKING_STORE): new macro.
5751 * continuations.h: support ia64 register backing store.
5752 (struct scm_t_contregs): add ia64 register backing store.
5754 * continuations.c: support ia64 register backing store.
5755 (continuation_mark): mark ia64 register backing store.
5756 (continuation_free): free ia64 register backing store.
5757 (scm_make_continuation): capture ia64 register backing store.
5758 (copy_stack_and_call): copy ia64 register backing store.
5760 2001-10-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
5762 * hashtab.c (scm_hash_fn_create_handle_x): The result of assoc_fn
5763 is known to be #f if no entry is found. Thus, use !SCM_FALSEP
5764 instead of SCM_NIMP to test for that case.
5766 * strings.h (SCM_SET_STRING_LENGTH): Cast the length to
5767 scm_t_bits instead of long.
5769 2001-10-06 Marius Vollmer <mvo@zagadka.ping.de>
5771 * tags.h (SCM_T_BITS_MAX, SCM_T_SIGNED_BITS_MAX,
5772 SCM_T_SIGNED_BITS_MIN): New.
5773 * numbers.h (SCM_MOST_POSITIVE_FIXNUM, SCM_MOST_NEGATIVE_FIXNUM):
5774 Use them to make these macros computable by the preprocessor.
5776 * num2integral.i.c (INTEGRAL2NUM): Let the preprocessor test
5777 whether the integral type fits in a fixnum, not the compiler.
5778 This removes a spurious compiler warning. Also, honor the
5779 NO_PREPRO_MAGIC flag to suppress any preprocessor tests. This is
5780 needed for `long long's.
5782 * numbers.c: Define NO_PREPRO_MAGOC when including
5783 num2integral.c.i for `long long' and `signed long long'.
5785 2001-10-06 Mikael Djurfeldt <mdj@linnaeus>
5787 These changes fixes a race condition in the Guile coop - pthread
5790 * coop.c (mother_awake_p): New variable.
5791 (coop_create): Set mother_awake_p before creating or signalling
5792 mother; wait until mother is going to sleep before returning.
5793 (mother): Reset mother_awake_p before going to sleep.
5795 2001-10-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
5797 * options.c (protected_objects, scm_init_options): The content of
5798 protected_objects is now protected from garbage collection using
5799 scm_gc_register_root instead of scm_permanent_object.
5801 (get_option_setting): New static function that computes an option
5802 setting as it was formerly done in the function scm_options.
5804 (get_documented_option_setting): New static function that
5805 returns option documentation as it was formerly done in the
5806 function scm_options. Note that documentation C strings are no
5807 longer precomputed into SCM objects. Instead, they are converted
5808 into SCM strings every time get_documented_option_setting is
5811 (change_option_setting): New static functions that modifies the
5812 option setting as it was formerly done in the function
5813 scm_options. The function is now exception safe, i. e. won't
5814 cause a memory leak when interrupted. Further, only non-immediate
5815 option values are added to the protection list.
5817 (scm_options): This function now has only the purpose to dispatch
5818 to to get_option_setting, get_documented_option_setting or
5819 change_option_setting, depending on the arguments given to
5822 (scm_init_opts): Don't convert documentation C strings into SCM
5823 strings. Further, don't protect any object values: They _must_
5824 be immediate values, otherwise there is no guarantee that they
5825 have not been collected before anyway.
5827 * options.[ch] (scm_t_option): Made type unsigned, name into a
5828 constant char* and val into a scm_t_bits type.
5830 (scm_options, scm_init_opts): The number of options is guaranteed
5831 to be larger or equal to zero. Thus, the type is changed to
5834 2001-10-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
5836 * num2integral.i.c (NUM2INTEGRAL): Eliminated some warnings about
5837 testing an unsigned value for being >= 0.
5839 2001-10-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
5841 * numbers.h: Removed old comment about using SCM_CAR to access
5844 (SCM_MOST_POSITIVE_FIXNUM, SCM_MOST_NEGATIVE_FIXNUM): Make sure
5845 the return value is signed. Thanks to Brian Crowder for the bug
5848 (SCM_SRS): Avoid unnecessary casting and don't unpack input
5849 values. With this patch, SCM_SRS can be safely used for other
5850 types than scm_t_signed_bits. However, it should still better be
5851 an internal macro and thus be renamed to SCM_I_SRS.
5853 (SCM_MAKINUM, SCM_INUM): Use proper casting.
5855 2001-10-03 Gary Houston <ghouston@arglist.com>
5857 * continuations.h, unif.h: in the descriptions of the bit patterns
5858 of the heap cells, make bit 0 the least significant.
5860 2001-09-25 Thien-Thi Nguyen <ttn@glug.org>
5862 * chars.h (SCM_MAKE_CHAR): Use `scm_t_bits' instead of `intptr_t'.
5863 Thanks to Golubev I. N.
5865 2001-09-25 Gary Houston <ghouston@arglist.com>
5867 * ports.c (scm_drain_input): extended the docstring. thanks to
5868 Alex Schroeder and Thien-Thi Nguyen.
5870 2001-09-23 Mikael Djurfeldt <mdj@linnaeus>
5872 * validate.h (SCM_NUM2FLOAT, SCM_NUM2DOUBLE,
5873 SCM_VALIDATE_FLOAT_COPY, SCM_VALIDATE_DOUBLE_COPY): New
5874 macros. (The NUM names might soon change.)
5876 * numbers.h: Added missing declarations.
5878 2001-09-22 Mikael Djurfeldt <mdj@linnaeus>
5880 * Makefile.am: Distribute num2float.i.c.
5882 * num2float.i.c: New file, multiply included by numbers.c, used
5883 to "templatize" the float <-> num conversion routines.
5885 * numbers.c: New functions: scm_num2float, scm_float2num,
5886 scm_num2double, scm_double2num.
5888 2001-09-21 Rob Browning <rlb@defaultvalue.org>
5890 * .cvsignore: really add version.h
5892 * strings.h (SCM_SET_STRING_LENGTH): coerce "l" to a long.
5893 Otherwise it fails on the alpha. However, we might rather choose
5894 this size conditionally.
5896 * numbers.c (scm_gcd): change "k" to a long from an int.
5897 Otherwise it fails on the alpha. However, we might rather choose
5898 this size conditionally.
5900 * error.c (scm_wta): coerce char* to intptr_t before int
5903 * debug.c (debugobj_print): coerce scm_intprint arg 1 to long, not
5906 * chars.h (SCM_MAKE_CHAR): coerce value to intptr_t.
5908 2001-09-20 Mikael Djurfeldt <mdj@linnaeus>
5910 * numbers.c (scm_integer_expt): Accept inexact integer in second
5911 argument. (Thanks to Bill Schottstaedt.)
5913 2001-09-20 Rob Browning <rlb@defaultvalue.org>
5915 * .cvsignore: add version.h
5917 * versiondat.h.in: removed (obsolete).
5919 * version.h.in: renamed from version.h.
5920 (SCM_GUILE_MAJOR_VERSION): new public macro.
5921 (SCM_GUILE_MINOR_VERSION): new public macro.
5922 (SCM_GUILE_MICRO_VERSION): new public macro.
5924 * version.h: renamed to version.h.in.
5927 (scm_major_version): support integer *_VERSION macros.
5928 (scm_minor_version): support integer *_VERSION macros.
5929 (scm_micro_version): support integer *_VERSION macros.
5930 (scm_version): support integer *_VERSION macros.
5932 2001-09-20 Mikael Djurfeldt <mdj@linnaeus>
5934 * error.c, error.h: Made error keys globally accessible.
5935 Applications might want to test for these or use them in a direct
5938 * num2integral.i.c (NUM2INTEGRAL): Report an error when these
5939 routines are passed an inexact. This change in behavior is
5940 motivated by concordance with R5RS: It is more common that a
5941 primitive doesn't want to accept an inexact for an exact.
5943 2001-09-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
5945 The following patch partially undoes my patch from 2001-06-30,
5946 where I added the function scm_gc_mark_cell_conservatively. The
5947 function is buggy, since it breaks guile during conservative
5948 marking if a pointer on the stack points directly into the list of
5949 free cells on the heap: With conservative cell marking this will
5950 cause the whole free list to be scanned and marked - boom!
5952 * gc.c (allocated_mark, MARK, heap_segment,
5953 scm_gc_mark_cell_conservatively, scm_init_storage), gc.h
5954 (scm_gc_mark_cell_conservatively): Remove function
5955 scm_gc_mark_cell_conservatively and update the corresponding
5956 comments and uses accordingly. Thanks to Christopher Cramer for
5957 the patch. (Minor corrections by me.)
5959 2001-09-15 Gary Houston <ghouston@arglist.com>
5961 * root.h (scm_root_state): removed the continuation_stack and
5962 continuation_stack_ptr members, which have no apparent purpose.
5963 (scm_continuation_stack, scm_continuation_stack_ptr): #defines
5966 * root.c (root_mark), init.c (restart_stack, start_stack), gc
5967 (scm_igc): remove all references to contination_stack and
5968 continuation_stack_ptr, avoiding allocation of a vector and
5969 useless processing during gc.
5971 2001-09-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
5973 * guardians.c (tconc_t, t_tconc): Renamed tconc_t to t_tconc.
5975 (TCONC_IN): Make sure that the cell word 0 is initialized last.
5977 (guardians_t, t_guardians): Renamed guardians_t to t_guardians.
5979 (GUARDIAN, GUARDIAN_DATA): Renamed GUARDIAN to GUARDIAN_DATA.
5981 (guardian_apply, scm_get_one_zombie, scm_make_guardian,
5982 mark_and_zombify): Prefer !SCM_<foo> over SCM_N<foo>.
5984 2001-09-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
5986 * guardians.c (mark_dependencies_in_tconc,
5987 whine_about_self_centered_zombies, scm_init_guardians): Register
5988 the static global variable `self_centered_zombies' via
5989 scm_gc_register_root, to make some cdr-ing unnecessary.
5991 2001-09-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
5993 * backtrace.c (display_backtrace_file,
5994 display_backtrace_file_and_line): Use SCM_EQ_P when comparing SCM
5995 values, use SCM_FALSEP when comparing SCM values against #f.
5996 Thanks to Rob Browning for the bug report.
5998 2001-09-12 Martin Baulig <martin@home-of-linux.org>
6000 * strings.[ch] (scm_str2string): New function.
6002 2001-09-06 Marius Vollmer <mvo@zagadka.ping.de>
6004 * gc.c (scm_done_free): Always subtract size from scm_mallocated
6005 when computing nm, even if it's negative.
6006 (scm_must_malloc): Abort on overflow of scm_mtrigger.
6007 (scm_must_realloc): Likewise.
6009 2001-09-01 Michael Livshin <mlivshin@bigfoot.com>
6011 * numbers.c (scm_sys_check_number_conversions): new function,
6012 defined if Guile is compiled in debugging mode. currently checks
6013 `scm_num2ulong', should check much much more.
6015 * num2integral.i.c (NUM2INTEGRAL): when converting a bignum to
6016 unsigned, ensure that it's positive. thanks to Martin Baulig!
6018 2001-08-31 Dirk Herrmann <D.Herrmann@tu-bs.de>
6020 * __scm.h: Added new section about compile time selectable
6023 (long_long, ulong_long, scm_sizet, SCM_WNA, SCM_OUTOFRANGE,
6024 SCM_NALLOC, SCM_HUP_SIGNAL, SCM_INT_SIGNAL, SCM_FPE_SIGNAL,
6025 SCM_BUS_SIGNAL, SCM_SEGV_SIGNAL, SCM_ALRM_SIGNAL, SCM_GC_SIGNAL,
6026 SCM_TICK_SIGNAL, SCM_SIG_ORD, SCM_ORD_SIG, SCM_NUM_SIGS):
6029 * deprecation.c (scm_include_deprecated_features): Simplified.
6031 * eval.c (EVALCAR, unmemocopy), eval.h (SCM_XEVALCAR): Use
6032 `SCM_IMP´ instead of `!SCM_CELLP´.
6034 * eval.c (unmemocopy): Eliminate redundant SCM_CELLP tests.
6035 Extract side-effecting operations from macros.
6037 (scm_init_eval): Don't initialize *top-level-lookup-closure*,
6038 scm_top_level_lookup_closure_var and scm_system_transformer.
6040 * gc.c (CELL_P): New local definition to replace SCM_CELLP.
6042 (heap_segment): Use CELL_P instead of SCM_CELLP.
6044 * init.c (start_stack): Don't initialize
6045 scm_top_level_lookup_closure_var and scm_system_transformer.
6047 * modules.c (scm_set_current_module): Don't access
6048 scm_top_level_lookup_closure_var and scm_system_transformer.
6050 (scm_sym2var): Don't call scm_variable_set_name_hint.
6052 (scm_post_boot_init_modules): Removed deprecated initializations.
6054 * print.c (scm_ipruk): Don't access cell contents of non cells.
6056 * strings.c (scm_string_set_x): All strings are writable.
6058 * strings.h (SCM_STRINGP): Use SCM_TYP7 to determine the string
6059 type. There is only one string type now.
6061 (SCM_STRING_COERCE_0TERMINATION_X): Deprecated.
6063 * tags.h: Remove comments about two different string types.
6065 (SCM_CELLP, SCM_NCELLP): Deprecated.
6067 * variable.c (make_variable): Remove code variant for vcells.
6069 * variable.h (SCM_VARIABLE_REF, SCM_VARIABLE_SET,
6070 SCM_VARIABLE_LOC): Remove code variant for vcells.
6072 * __scm.h, deprecation.[ch]: Renamed SCM_DEBUG_DEPRECATED to
6073 SCM_ENABLE_DEPRECATED with the logic reversed.

6618 2001-07-08 Rob Browning <rlb@defaultvalue.org>
6620 * .cvsignore: add stamp-h.in.
6622 2001-07-04 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
6624 * hooks.c (scm_make_hook, scm_add_hook_x),
6625 (scm_remove_hook_x, scm_reset_hook_x, scm_run_hook): Added return
6626 value info to the docstrings.
6628 2001-07-03 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
6630 Some more compatibility patches for Windows.
6632 * posix.c (getlogin): getlogin() implementation for Windows.
6634 * backtrace.c, ioext.c: Include <stdio.h>.
6636 * unif.c, script.c, rw.c, error.c: Include <io.h>, if it does
6639 * cpp_sig_symbols.in: Added SIGBREAK.
6641 2001-07-01 Marius Vollmer <mvo@zagadka.ping.de>
6643 * strports.c (scm_read_0str, scm_eval_0str): Call
6644 scm_c_read_string and scm_c_eval_string respectively, not
6645 themselves. Thanks to Dale P. Smith!
6647 2001-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
6649 * unif.c (scm_array_set_x): The variable args does not
6650 necessarily have to be a list. Further, got rid of a redundant
6653 2001-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
6655 * list.c (SCM_I_CONS): Make sure the cell type is initialized
6658 * gc.c (s_scm_map_free_list, scm_igc, scm_gc_sweep,
6659 init_heap_seg): Fixed signedness.
6661 (init_heap_seg): Replaced strange for-loop with a while loop.
6663 * weaks.h (WEAKSH, SCM_WEAKS_H): Rename <foo>H to SCM_<foo>_H.
6665 (SCM_WVECTP): Prefer !SCM_<pred> over SCM_N<pred>.
6667 The following patch adds conservative marking for the elements of
6668 free or allocated cells.
6670 * gc.c (allocated_mark, heap_segment): New static functions.
6672 (which_seg): Deleted, since the functionality is now provided by
6673 function heap_segment.
6675 (map_free_list): Use heap_segment instead of which_seg.
6677 (MARK): If cell debugging is disabled, mark free cells
6680 (scm_mark_locations, scm_cellp): Extracted the search for the
6681 heap segment of a SCM value into function heap_segment.
6683 (scm_init_storage): Allocated cells must be marked
6686 * gc.[ch] (scm_gc_mark_cell_conservatively): New function.
6688 The following patch changes the representation of weak vectors to
6689 double cells instead of using an extension of the vector's
6692 * gc.c (MARK): Use SCM_SET_WVECT_GC_CHAIN instead of assigning to
6693 the result of SCM_WVECT_GC_CHAIN.
6695 (scm_gc_sweep): Weak vectors don't have extra fields any more.
6697 * weaks.c (allocate_weak_vector): New static function. It does
6698 not patch any previously created vector object during the
6699 construction of a weak vector, and thus doesn't need to switch
6700 off interrupts during vector creation.
6702 (scm_make_weak_vector, scm_make_weak_key_hash_table,
6703 scm_make_weak_value_hash_table, scm_make_doubly_weak_hash_table):
6704 Use allocate_weak_vector to provide the new weak vector object.
6706 * weaks.h (SCM_WVECT_TYPE, SCM_SET_WVECT_TYPE,
6707 SCM_SET_WVECT_GC_CHAIN): New macros. The weak vector subtype is
6708 now stored in the double cell.
6710 (SCM_IS_WHVEC, SCM_IS_WHVEC_V, SCM_IS_WHVEC_B, SCM_IS_WHVEC_ANY):
6713 (SCM_WVECT_GC_CHAIN): The weak objects are now chained together
6714 using an entry of the double cell.
6716 2001-06-30 Thien-Thi Nguyen <ttn@revel.glug.org>
6718 * stamp-h.in: bye bye
6720 2001-06-30 Marius Vollmer <mvo@zagadka.ping.de>
6722 * gh_eval.c (gh_eval_str): Use scm_c_eval_string instead of
6725 * load.c, load.h (scm_c_primitive_load,
6726 scm_c_primitive_load_path): New.
6728 * strports.c, strports.h (scm_c_read_string): Renamed from

6730 (scm_c_eval_string): Renamed from scm_eval_0str.
6731 (scm_read_0str, scm_eval_0str): Deprecated.
6733 2001-06-28 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>

6740 * list.h (scm_list_1, scm_list_2, scm_list_3, scm_list_4, scm_list_5,
6741 scm_list_n): New functions.

6743 SCM_LIST6, SCM_LIST7, SCM_LIST8, SCM_LIST9, scm_listify): Deprecated.
6744 (lots of files): Use the new functions.
6746 * goops.c (CALL_GF1, CALL_GF2, CALL_GF3, CALL_GF4): Use scm_call_N.
6748 * strings.c: #include "libguile/deprecation.h".
6750 2001-06-27 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
6752 * read.c (scm_lreadr): When reading a hash token, check for a
6753 user-defined hash procedure first, so that overriding the builtin
6754 hash characters is possible (this was needed for implementing
6755 SRFI-4's read synax `f32(...)').
6757 * num2integral.i.c: Use scm_t_signed_bits instead of scm_t_bits,
6758 because the latter is unsigned now and breaks comparisons like
6759 (n < (scm_t_signed_bits)MIN_VALUE).
6761 2001-06-26 Neil Jerram <neil@ossau.uklinux.net>
6763 * eval.h, eval.c (scm_call_4): New function.
6765 * eval.c (SCM_APPLY, SCM_CEVAL, ENTER_APPLY): Call trap handlers
6766 directly rather than dispatching to them via scm_ithrow and a lazy
6769 * eval.c (scm_evaluator_trap_table), eval.h (SCM_ENTER_FRAME_HDLR,
6770 SCM_APPLY_FRAME_HDLR, SCM_EXIT_FRAME_HDLR): Add three new options
6771 for trap handler procedures.
6773 * debug.h (SCM_RESET_DEBUG_MODE): Add checks for trap handler
6774 procedures not being #f.
6776 2001-06-27 Michael Livshin <mlivshin@bigfoot.com>
6778 * Makefile.am (c-tokenize.c): add rule to generate it.
6779 (EXTRA_DIST): add c-tokenize.lex, so it gets distributed.
6781 filter-doc-snarfage.c: remove.
6783 2001-06-26 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
6785 * ports.c (scm_output_port_p): Use result of SCM_COERCE_OUTPORT.
6787 The following set of changes makes compiling Guile under various
6788 Windows compilers easier. Compilation under GNU systems should
6789 not be affected at all.
6791 Thanks to Stefan Jahn for all necessary information, patches and
6794 * posix.c: Conditialize getpwent, getgrent, kill, getppid, getuid,

6802 Windows and conditionalize some signal names.
6804 * socket.c (scm_getsockopt): Added missing comma.
6805 Include socket library header under Windows.
6807 * stime.c (CLKTCK): Add cast to int, to make it compile under

6817 * guile.c (inner_main): Under Windows, initialize socket library
6818 and initialize gdb_interface data structures.
6820 * gdb_interface.h: Under Windows, gdb_interface cannot be
6821 initialized statically. Initialize at runtime instead.
6823 * fports.c (write_all): ssize_t -> size_t.
6824 (fport_print): Conditionalize call to ttyname().
6825 (getflags): New function, compiled only under Windows.
6827 * filesys.c: Conditionalize inclusion of <pwd.h>. Conditionalize
6828 primitives chown, link, fcntl.
6829 (scm_basename, scm_dirname): Under Windows, handle \ as well as /
6832 * backtrace.c: Include <io.h> under Windows.

6870 * filesys.c (scm_close), ports.c (scm_close_port,
6871 scm_port_closed_p), strop.c (scm_string_null_p): Use SCM_BOOL

6911 * validate.h (SCM_VALIDATE_SUBSTRING_SPEC_COPY): Eliminate
6912 warning about comparing signed and unsigned values. This fix is
6913 not optimal, since it won't work reliably if sizeof (c_start) >
6914 sizeof (size_t) or sizeof (c_end) > sizeof (size_t). A better
6915 solution is to define this macro as an inline function, thus
6916 allowing to specifiy the types of c_start and c_end.
6918 2001-06-25 Dirk Herrmann <D.Herrmann@tu-bs.de>

6942 (scm_last_stack_frame): Remove bogus `;´.
6944 * stacks.h (SCM_FRAMEP): Fix type check.

6974 2001-06-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
6976 * backtrace.c (display_backtrace_body): Use SCM_VALIDATE_STACK
6977 and SCM_VALIDATE_OPOUTPORT instead of SCM_ASSERT. Fix signedness
6980 * backtrace.c (display_expression, scm_set_print_params_x,
6981 display_application, display_frame, scm_backtrace), numbers.c
6982 (scm_istring2number), objects.c (scm_class_of,
6983 scm_mcache_lookup_cmethod, scm_mcache_compute_cmethod): Prefer

7014 2001-06-19 Gary Houston <ghouston@arglist.com>
7016 * filter-doc-snarfage.c (process): added ungetc in
7017 MULTILINE_COOKIE case since otherwise it fails when there's no
7018 space between the '(' and the quote of the following string
7021 2001-06-14 Marius Vollmer <mvo@zagadka.ping.de>
7023 Throughout: replace "scm_*_t" with "scm_t_*", except "scm_lisp_t".
7025 2001-06-14 Marius Vollmer <mvo@zagadka.ping.de>
7027 * unif.h (SCM_ARRAY_NDIM): Shift then cast so that no sign

7053 the macro definition.
7055 (SCM_CLASSP, SCM_INSTANCEP, SCM_PUREGENERICP, SCM_ACCESSORP,
7056 SCM_SIMPLEMETHODP, SCM_FASTMETHODP): Use SCM_STRUCT_VTABLE_FLAGS

7457 scm_array_dim->scm_array_dim_t to enable build with
7458 --disable-deprecated.
7460 2001-05-24 Michael Livshin <mlivshin@bigfoot.com>
7462 The purpose of this set of changes is to regularize Guile's usage
7463 of ANSI C integral types, with the following ideas in mind:
7465 - SCM does not nesessarily have to be long.
7466 - long is not nesessarily enough to store pointers.
7467 - long is not nesessarily the same size as int.
7469 The changes are incomplete and possibly buggy. Please test on

8633 mode, as suggested by Michael Livshin.
8635 2001-03-31 Michael Livshin <mlivshin@bigfoot.com>
8637 * backtrace.c (display_backtrace_body): since the `print_state'
8638 variable is not used (instead its data field is used directly as
8639 `pstate'), protect it from the hungry compiler optimizations.
8640 thanks to Bill Schottstaedt for the report.
8642 2001-03-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
8644 * gc.[ch] (scm_tc16_allocated): New type tag for allocated cells.
8645 It is only defined and used if guile is compiled with
8646 SCM_DEBUG_CELL_ACCESSES set to true. It's purpose is, to never
8647 let cells with a free_cell type tag be visible outside of the
8648 garbage collector when in debug mode.
8650 * gc.c (scm_debug_cell_accesses_p): Set to true as default.
8652 (scm_assert_cell_valid): Use a local static variable to avoid
8655 (MARK): Only check for rogue cell pointers in debug mode. Use
8656 scm_cellp for this purpose and place all checks for rogue pointers
8657 into that function. Further, since due to conservative scanning
8658 we may encounter free cells during marking, don't use the standard
8659 cell type accessor macro to determine the cell type.
8661 (scm_cellp): Check if the cell pointer actually points into a
8664 (scm_init_gc): Initalize scm_tc16_allocated.
8666 * gc.h (GCH): Renamed to SCM_GC_H.
8668 (SCM_VALIDATE_CELL): Enclose the expression in brackets. This
8669 might be unnecessary, but I feel better this way :-)
8671 (SCM_GC_CELL_TYPE): New macro.
8673 (SCM_SETAND_CDR, SCM_SETOR_CDR): Deprecated. These are not used
8674 in guile, and it is unlikely that they will be applied to real
8677 (SCM_SET_FREE_CELL_TYPE): Removed. It was not used.
8679 (SCM_GC_SET_ALLOCATED): New macro. Only non-empty if guile is
8680 compiled with SCM_DEBUG_CELL_ACCESSES set to true.
8682 (SCM_NEWCELL, SCM_NEWCELL2): Use of SCM_GC_SET_ALLOCATED will
8683 make sure that in debug mode no free cell will ever be visible
8684 outside of the garbage collector.
8686 2001-03-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
8688 * async.c (scm_asyncs_pending): Don't use != to compare SCM

8695 Remove suspicious use of SCM_SLOPPY_CONSP.
8697 * eq.c (scm_equal_p), tags.h (SCM_ECONSP): Use SCM_CONSP instead
8698 of SCM_SLOPPY_CONSP. A sane compiler should be able to perform
8699 the corresponding optimization.
8701 * eval.c (iqq): Use proper type check.
8703 (scm_m_expand_body): Remove redundant type checks.
8705 (promise_print): Don't access promise cells as pairs.
8707 * eval.c (EVALCAR, iqq, scm_m_expand_body, scm_eval_args,
8708 scm_deval_args SCM_CEVAL), guardians.c (scm_guard), hashtab.c
8709 (scm_internal_hash_fold), print.c (scm_iprlist): Use !SCM_CELLP
8710 for SCM_NCELLP, !SCM_CONSP for SCM_NCONSP, !SCM_IMP for SCM_NIMP,
8711 !SCM_FALSEP for SCM_NFALSEP, !SCM_NULLP for SCM_NNULLP
8713 * eval.c (scm_m_define, scm_macroexp, SCM_CEVAL), print.c
8714 (scm_iprin1): Use new macro predicate and accessors.
8716 * eval.h (scm_tc16_macro): Removed declaration. It is declared
8719 * eval.h (EVALH), macros.h (MACROSH), ports.h (PORTSH), procs.h
8720 (PROCSH), tags.h (TAGSH), variable.h (VARIABLEH): Renamed to
8721 SCM_EVAL_H, SCM_MACROS_H, SCM_PORTS_H, SCM_PROCS_H, SCM_TAGS_H and
8722 SCM_VARIABLE_H. Even the macros that are used to inhibit
8723 including a header file twice should be in the SCM_ namespace.
8725 * fluids.c (scm_swap_fluids, scm_swap_fluids_reverse),
8726 properties.c (scm_primitive_property_ref,
8727 scm_primitive_property_del_x): Prefer stronger predicates like
8728 SCM_NULLP or SCM_FALSEP over SCM_IMP.
8730 * gc.c (MARK): Use proper macros to access procedure-with-setter
8731 cell elements and closure cell elements.
8733 (gc_sweep_freelist_finish, scm_gc_sweep, init_heap_seg): Don't
8734 access free cells as pairs.
8736 (scm_unprotect_object): scm_hashq_get_handle returns #f if
8737 no hashtab entry is found.
8739 * gc.c (scm_gc_sweep), ports.c (scm_close_port): Use new macro
8740 SCM_CLR_PORT_OPEN_FLAG.
8742 * guardians.c (TCONC_IN), print.c (scm_free_print_state): Don't
8743 use SCM_SET_C[AD]R for uninitialized cells.
8745 * hashtab.c (scm_hash_fn_get_handle): Use SCM_VALIDATE_VECTOR.
8746 If the hashtable has no slots, return #f instead of '(). This
8747 unifies the return value with most assoc-functions.
8749 (scm_hash_fn_ref): Use proper type check.
8751 (scm_hashq_get_handle, scm_hashv_get_handle, scm_hash_get_handle):
8752 Removed references to non-existing functions from documentation.
8754 * keywords.c (scm_keyword_dash_symbol): Use proper macros to
8755 access keyword cell elements.

8776 scm_variable_set_x): Use proper macros to access variable cell
8779 (scm_variable_bound_p): Don't use SCM_NEGATE_BOOL.
8781 * variable.h (SCM_VARVCELL): Don't access variable cells as
8784 * vectors.c (scm_vector), weaks.c (scm_weak_vector): Simplified,
8785 added FIXME comment, removed register specifier.
8787 2001-03-29 Keisuke Nishida <kxn30@po.cwru.edu>
8789 * goops.c, goops.h (scm_init_oop_goops_goopscore_module): Deprecated.

8792 2001-03-27 Marius Vollmer <mvo@zagadka.ping.de>
8794 * eval.c (SCM_APPLY): Check that arg1 is bound for scm_tc7_cxr.

8819 New delcarations to support above change.
8821 * eval.c (scm_primitive_eval_x, scm_primitive_eval): Fix syntax
8822 errors with last change.
8824 2001-03-25 Marius Vollmer <mvo@zagadka.ping.de>

8993 * gh.h/gh_data.c (gh_ints2scm): Changed the signature to use a
8994 const int* to reflect that the input array of integers remains
8995 unchanged. Thanks to Brett Viren for the hint.
8997 2001-03-14 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
8999 * gh_data.c (gh_scm2chars, gh_scm2shorts, gh_scm2longs),
9000 (gh_scm2floats, gh_scm2doubles): Check for malloc() returning NULL
9002 (gh_scm2newstr, gh_symbol2newstr): Change call to
9003 scm_must_malloc() to malloc(), because user-free()able memory is

9008 2001-03-13 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
9010 * ports.c (scm_port_mode): Changed `mode' array size to 4.

9020 * goops.h (SCM_VALIDATE_PUREGENERIC): New macro.
9022 * goops.c (scm_m_atslot_ref, scm_m_atslot_set_x,
9023 scm_m_atdispatch): Provide definitions for FUNC_NAME. Don't use
9024 SCM_ASSYNT to check for correct argument types. Either use some
9025 SCM_VALIDATE_* macro or an explicit test.
9027 (scm_make_foreign_object): Don't use SCM_ASSERT to check for
9030 * macros.h (SCM_ASSYNT): On assertion failure, issue a misc-error
9031 instead of calling scm_wta.
9033 2001-03-12 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
9035 * load.c (scm_primitive_load, scm_primitive_load_path),

9050 Use SCM_LISTn instead of scm_listify.
9052 2001-03-10 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
9054 * _scm.h: Removed #include <errno.h>.
9056 * error.c, net_db.c, putenv.c, stime.c: Removed declaration of
9057 errno variable (can be a macro on some systems, for example when
9058 using linux libc with threads).
9060 * error.c, filesys.c, gc.c, ioext.c, iselect.c, net_db.c, ports.c,
9061 posix.c, print.c, putenv.c, scmsigs.c, script.c, simpos.c, smob.c,
9062 socket.c, srcprop.c, stime.c, strop.c, unif.c, vports.c: Added
9063 #include <errno.h> in these 20 out of 100 files.
9065 2001-03-10 Gary Houston <ghouston@arglist.com>

9078 * posix.c: Replaced `#define' of __USE_XOPEN right before
9079 including unistd.h with a define of _GNU_SOURCE at the very top of

9104 2001-03-09 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
9106 * posix.h (scm_crypt, scm_chroot, scm_getlogin, scm_cuserid),
9107 (scm_getpriority, scm_setpriority, scm_getpass, scm_flock),
9108 (scm_sethostname, scm_gethostname): New prototypes.
9110 * posix.c: Added inclusion of <crypt.h>, <sys/resource.h> and

9115 (scm_getpriority, scm_setpriority, scm_getpass, scm_flock),
9116 (scm_sethostname, scm_gethostname): New procedures.
9118 2001-03-08 Neil Jerram <neil@ossau.uklinux.net>
9120 * ports.c (scm_port_column): Docstring fixes: (i) port-line arg is
9121 not optional (ii) "recommend" spelling correction.
9123 2001-03-08 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
9125 * ramap.c (racp): Removed optimization which caused array copying
9126 to fail if the two arrays shared storage. Re-inserted the IVDEP
9127 macros removed in the change of 2000-03-09. (Don't really have a
9128 complete grasp of what they are for, but they seem to be necessary
9129 on Crays. This needs testing!) Thanks to Miroslav Silovic.
9131 * hash.c (scm_string_hash): Don't downcase characters.
9133 2001-03-07 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
9135 * symbols.c (scm_symbols_prehistory): Changed symbol hash table
9136 size from 277 --> 1009.

9148 (*.doc): Add dependency on guile-snarf.awk.in.
9150 * guile-snarf.awk.in: Neglect spaces at the end of
9151 SCM_SNARF_DOCSTRING_END. Skip lines "# NN ..." in the
9152 middle of docstrings. (To avoid the problem with gcc-2.96.)
9154 2001-03-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
9156 * coop-threads.c (scm_call_with_new_thread), load.c
9157 (scm_primitive_load, scm_sys_search_load_path), random.c
9158 (scm_c_default_rstate), struct.c (scm_make_struct_layout,
9159 scm_struct_ref, scm_struct_set_x): Don't use SCM_ASSERT to
9160 (potentially) issue a scm-misc-error or wrong-num-args error
9163 * load.c (scm_search_path): Use SCM_ASSERT_TYPE to give details
9164 about the expected type with the wrong-type-arg error message.
9166 * smob.c (scm_make_smob): Abort on misuse of smob - it indicates
9167 a C level bug that can't be fixed from scheme anyway.
9169 2001-03-05 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
9171 * eval.c (scm_m_letstar): Removed check for duplicate bindings.
9172 Duplicate bindings are OK in a let* since a let* is semantically
9173 equivalent to a nested set of let:s.
9175 2001-03-05 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
9177 * print.c (scm_print_options): Fixed texinfo in docstring.
9179 * net_db.c (scm_getserv, scm_getproto, scm_getnet): Return #f if
9180 the underlying functions getservent, getprotoent or getnetent
9181 return NULL instead of signalling an error.
9183 2001-03-04 Gary Houston <ghouston@arglist.com>
9185 * socket.c (scm_fill_sockaddr): don't allow buffer overflows when
9186 taking an unexpectedly large filename for an AF_UNIX socket from
9187 bind/connect/sendto (thanks to Martin Grabmueller).
9189 * socket.c (scm_sock_fd_to_port, SCM_SOCK_FD_TO_PORT): removed the
9190 former and adjusted the latter.
9191 (scm_socket, scm_socketpair): cosmetic changes.
9192 (scm_getsockopt, scm_setsockopt): declare optlen as int, not
9193 size_t as socklen_t substitute. don't restrict args/return values
9194 to INUM: allow full range of int or size_t.
9195 (scm_fill_sockaddr): check arguments before allocating memory, to
9196 avoid leakage. use malloc, not scm_must_malloc.
9197 (scm_connect, scm_bind, scm_sendto): use int, not size_t as socklen_t
9198 substitute. free the sockaddr structure before throwing an error.
9199 (scm_init_add_buffer): procedure removed, together with its static
9200 buffer scm_addr_buffer, which wouldn't be thread safe. instead,
9201 define a macro MAX_ADDR_SIZE and declare the buffer where needed.
9202 (scm_accept, scm_getpeername, scm_getsockname, scm_recvfrom,
9203 scm_sendto): use a local buffer instead of scm_addr_buffer.
9204 adjust for new SCM_SOCK_FD_TO_PORT. use int for address size,
9206 (scm_recvfrom): set addr->sa_family to AF_UNSPEC before the recvfrom
9207 call to detect whether recvfrom could be bothered to set the address.
9208 (scm_init_socket): don't call scm_init_addr_buffer.
9210 2001-03-04 Dirk Herrmann <D.Herrmann@tu-bs.de>

9221 scm_array_to_list, scm_array_prototype), validate.h
9222 (SCM_VALIDATE_NUMBER_COPY): Don't call function scm_wta, call
9223 scm_misc_error or scm_wrong_type_arg instead.
9225 * validate.h (SCM_WTA, RETURN_SCM_WTA): Deprecated.
9227 2001-03-04 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
9229 * goops.c, goops.h (scm_sys_pre_expand_closure_x): Removed.
9230 (scm_sys_tag_body): Added.
9232 2001-03-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
9234 * continuations.c (continuation_apply), eval.c (scm_m_lambda,

9240 scm_lreadparen, scm_lreadrecparen), script.c (script_get_octal,
9241 script_get_backslash, script_read_arg), unif.c (scm_cvref): Don't
9242 call function scm_wta, call scm_misc_error or scm_wrong_type_arg
9245 2001-03-04 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
9247 * goops.c (scm_sys_pre_expand_closure_x): New procedure.

9257 immediate, literal constant should be evaluated.
9258 * eval.c (scm_s_duplicate_formals): New error message string.
9259 (scm_c_improper_memq): New function.
9260 (scm_m_lambda): Check for duplicate arguments.
9261 (scm_ceval, scm_deval): When executing a body: only cons a new
9262 toplevel environment frame when it is different from the
9263 existing one; use EVALCAR instead of SIDEVAL so that we can properly
9264 check for empty combinations; use SCM_EVALIM2 for the same reason
9265 in the non-toplevel loop.
9266 (nontoplevel_cdrxnoap, nontoplevel_cdrxbegin, nontoplevel_begin):
9267 New labels with the meaning of their non-"nontoplevel" partners,
9268 but they are used when it is known that the body is not evaluated at
9270 (scm_apply, scm_dapply): use SCM_EVALIM2 to get proper error
9271 reporting for empty combinations.
9273 2001-03-02 Keisuke Nishida <kxn30@po.cwru.edu>
9275 * Remove dump facilities.
9276 * dump.c, dump.h: Removed.

9297 (scm_symbol_to_string, scm_string_to_symbol): Changed use of @t{}
9298 to @code{} as the texinfo manual recommends, converted the
9299 examples to use a @lisp{}-environment.

9323 2001-02-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
9325 * __scm.h (SCM_ASSERT_TYPE): Add missing macro parameter.
9326 (Obviously nobody compiles with SCM_RECKLESS defined...)

9338 * numbers.c (scm_two_doubles, scm_sys_expt, scm_sys_atan2,
9339 scm_make_polar): Rename arguments `z1' and `z2' to `x' and `y',
9340 since use of `z' suggests that the arguments may be complex.
9342 * goops.c (scm_make), numbers.c (scm_sys_expt): Fix docstring
9345 2001-02-23 Neil Jerram <neil@ossau.uklinux.net>
9347 * dump.c (scm_binary_write, scm_binary_read), eval.c

9359 module around the call to DEFVAR, scm_eval takes care of that.
9360 (scm_init_goops): Make scm_module_goops and
9361 scm_goops_lookup_closure permanent objects.
9363 * eval.c (scm_ceval, scm_deval): When evaluating expressions on
9364 top level, create a fresh top-level environment for each
9365 expression instead of mutating the exisint frame. This is
9366 important when that frame is closed over.
9368 * numbers.c (s_scm_logior) [SCM_DIGSTOOBIG]: Also use
9369 SCM_DIGSPERLONG instead of DIGSPERLONG.
9371 2001-02-21 Marius Vollmer <mvo@zagadka.ping.de>
9373 * eval.c (scm_ceval, scm_deval): Check for wrong number of args
9374 before applying arrow procedure in `cond' and before applying
9375 receiver procedure in call-with-current-continuation.
9376 (scm_i_eval): Do not invoke scm_copy_tree in argument in SCM_XEVAL
9377 macro. The argument is expanded more than one time.
9379 * numbers.c (scm_logior) [SCM_DIGSTOOBIG]: Correctly use
9380 SCM_BIGDIG instead of BIGDIG. Thanks to Steven G. Johnson!
9382 2001-02-20 Marius Vollmer <mvo@zagadka.ping.de>

9504 2001-02-13 Marius Vollmer <marius.vollmer@uni-dortmund.de>
9506 * gc_os_dep.c: Do not include <linux/version.h>. It makes no
9507 sense to compile for a specific kernel version. Do not include
9508 <asm/signal.h> while defining __KERNEL__. This hack should no

9511 2001-02-13 Marius Vollmer <mvo@zagadka.ping.de>
9513 * eval.c (scm_ceval, scm_deval): use `SIDEVAL' instead of

9532 names to better reflect their meaning.
9534 * eval.c (scm_ceval, scm_deval): Recognize when `begin' is being

9564 scm_selected_module to scm_current_module to synchronize Scheme
9566 (scm_select_module, scm_set_current_module): Likewise. Changed
9569 * ports.c (scm_port_for_each): Make a snapshot of the port table
9570 before iterating over it. The table might change while the user
9571 code is running. With the snapshot, the user can depend on the
9572 fact that each port that existed at the start of the iteration is
9573 encountered exactly once. (ice-9 popen) depends on this.
9575 2001-02-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
9577 * strings.h (SCM_STRING_MAX_LENGTH): New macro.
9579 * strings.c (scm_makstr, scm_take_str, scm_make_string): Added

9820 (SCM_OPDIRP): Deprecated.
9822 * filesys.c (scm_opendir): Use SCM_DIR_FLAG_OPEN instead of
9825 (scm_readdir, scm_rewinddir): Don't use SCM_VALIDATE_OPDIR.
9826 Instead, give an explicit error message in case the directory is
9829 (scm_closedir, scm_dir_print): Rewritten to use SCM_DIR_OPEN_P
9830 instead of SCM_OPENP and SCM_CLOSEDP.

9872 * __scm.h (SCM_FIXNUM_BIT): Added. The name is chosen in analogy
9873 to the names in limits.h.
9875 * numbers.c (abs_most_negative_fixnum): Added.
9877 (scm_quotient, scm_remainder): Fixed the fixnum-min / (abs
9878 fixnum-min) special case.
9880 (scm_big_and): Fix for negative first parameter.
9882 (scm_bit_extract): Fix for fixnum paramters.
9883 Thanks to Rob Browning for the bug report.
9885 (scm_init_numbers): Initialize abs_most_negative_fixnum.
9887 2001-01-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
9889 * symbols.c (scm_symbol_bound_p): Fixed comment.
9890 Thanks to Chris Cramer.
9892 2001-01-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
9894 * smob.[ch] (scm_make_smob_type): Return type is scm_bits_t now.

9899 from Matthias Köppe:
9901 * objects.h (SCM_SET_ENTITY_SETTER): new macro. SCM_ENTITY_SETTER
9902 casts its result, so doesn't yield an lvalue per ANSI C.
9904 * goops.c (s_scm_sys_set_object_setter_x): use
9905 SCM_SET_ENTITY_SETTER.
9906 (clear_method_cache): use SCM_SET_ENTITY_PROCEDURE.
9908 * gc.h (SCM_GC_SET_CARD_BVEC): new macro. SCM_GC_CARD_BVEC casts
9909 its result, so doesn't yield an lvalue per ANSI C.
9910 (SCM_GC_SET_CARD_FLAGS): ditto for SCM_GC_GET_CARD_FLAGS.
9911 (SCM_GC_CLR_CARD_FLAGS): redefined in terms of
9912 SCM_GC_SET_CARD_FLAGS.
9913 (SCM_GC_SET_CARD_FLAG, SCM_GC_CLR_CARD_FLAGS): ditto.
9915 * gc.c (INIT_CARD): use the explicit setter macro to set the bvec.
9917 2001-01-08 Gary Houston <ghouston@arglist.com>
9919 * validate.h (SCM_VALIDATE_SUBSTRING_SPEC_COPY): new macro.
9920 * ioext.c (scm_read_string_x_partial, scm_read_delimited_x),
9921 socket.c (scm_recvfrom): use the new macro, plus minor docstring
9923 * ioext.c (scm_read_string_x_partial): don't crash if -1 is supplied
9924 for fdes. if current input port is used, check that it's a file
9927 2001-01-06 Gary Houston <ghouston@arglist.com>
9929 * ioext.c (scm_read_string_x_partial): new procedure, implements
9930 read-string!/partial.
9931 * ports.c (scm_take_from_input_buffers): new procedure used by
9932 scm_read_string_x_partial.
9933 (scm_drain_input): use scm_take_from_input_buffers.
9935 2001-01-06 Marius Vollmer <mvo@zagadka.ping.de>
9937 * validate.h (SCM_VALIDATE_NUMBER): New.
9939 2001-01-03 Michael Livshin <mlivshin@bigfoot.com>
9941 * guardians.c (F_GREEDY, F_LISTED, F_DESTROYED, GREEDY_P,
9942 SET_GREEDY, LISTED_P, SET_LISTED, CLR_LISTED, DESTROYED_P,
9943 SET_DESTROYED): new defines/macros.
9944 (GUARDIAN_LIVE, GUARDIAN_ZOMBIES, GUARDIAN_NEXT): deleted.
9945 (add_to_live_list): takes a `guardian_t *' now, not SCM.
9946 (guardian_print): print more info.
9947 (guardian_apply): check if the guardian is destroyed, and throw an
9948 error if so. take one more optional argument `throw_p'.
9949 (scm_guard): depending on the value of `throw_p', return a boolean
9951 (scm_get_one_zombie): remove redundant property test.
9952 (guardian_t): represent the various (currently 3, I hope nothing
9953 more gets added) boolean fields as bit flags.
9954 (scm_guardian_destroyed_p, scm_guardian_greedy_p): new predicates.
9955 (scm_destroy_guardian_x): new procedure.
9957 * guardians.h: added prototypes for `scm_guardian_greedy_p' and
9958 `scm_guardian_destroyed_p'. changed prototype for `scm_guard'.
9960 2001-01-01 Gary Houston <ghouston@arglist.com>
9962 * fports.c (fport_write): bugfix: handle short writes for
9963 unbuffered ports too. optimize the buffered case by minimizing
9964 the number of write/flush calls.
9965 (write_all): new helper procedure.
