1 2008-06-02 Ludovic Courtès <ludo@gnu.org>
3 * deprecated.c (maybe_close_port): Rename EXCEPT to EXCEPT_SET
4 to workaround `#define except' on Tru64. Reported by Peter
5 O'Gorman <pogma@thewrittenword.com>.
7 2008-05-31 Ludovic Courtès <ludo@gnu.org>
9 * __scm.h (SCM_INTERNAL): New macro.
10 * *.h: Use it to mark as internal `scm_i_' and `scm_init_'
11 functions that are not used by public macros or inline
14 2008-05-14 Julian Graham <joolean@gmail.com>
16 * threads.c (fat_mutex)[recursive]: New field.
17 (make_fat_mutex): Adjust initialization to reflect changes to
18 mutex lock level semantics.
19 (fat_mutex_lock, fat_mutex_unlock): Add support for unowned
20 mutexes and locking mutexes on behalf of other threads.
21 (scm_lock_mutex, scm_lock_mutex_timed): Update to reflect
22 signature change to fat_mutex_lock.
23 (scm_mutex_owner, scm_mutex_level, scm_mutex_locked_p): New /
25 * threads.h (scm_mutex_owner, scm_mutex_level,
26 scm_mutex_locked_p): Prototypes for new functions.
28 2008-05-12 Neil Jerram <neil@ossau.uklinux.net>
30 * discouraged.c: Expand DEFFROM and DEFTO macros, to avoid
31 compiler warnings about excess semicolons. (Reported by Didier
34 2008-05-08 Neil Jerram <neil@ossau.uklinux.net>
36 * throw.c (scm_ithrow): For IA64 add a return statement, to
39 * threads.h (scm_i_thread): New IA64 fields:
40 register_backing_store_base and pending_rbs_continuation.
42 * threads.c (guilify_self_1): For IA64: cap RBS base address at
43 the current value of scm_ia64_ar_bsp, and store the capped value
45 (SCM_MARK_BACKING_STORE): Use thread->register_backing_store_base
46 instead of scm_ia64_register_backing_store_base().
47 (scm_threads_mark_stacks): Add "&" in "&t->regs", so that the code
48 works both for jmp_buf defined as an array, and jmp_buf defined as
51 * continuations.h (scm_t_contregs): Remove `fresh' and `ctx'
52 fields; these are now inside the IA64 definition of `jmp_buf'.
54 * continuations.c (scm_make_continuation): Simplify, by moving
55 some of the IA64 code inside the definition of "setjmp", and by
56 some obvious commonizations. For IA64 register backing store
57 (RBS) stack base, use thread->register_backing_store_base instead
58 of scm_ia64_register_backing_store_base().
59 (copy_stack): For IA64, store pointer to continuation being
60 invoked in thread state, so we can restore the continuation's RBS
61 stack just before the next setcontext call.
62 (copy_stack_and_call): Don't restore RBS stack explicitly here.
63 It will be restored, if appropriate, inside the longjmp call.
64 (scm_ia64_longjmp): New function.
66 * __scm.h (setjmp, longjmp, jmp_buf): For IA64, implement using
67 getcontext and setcontext.
69 2008-05-07 Ludovic Courtès <ludo@gnu.org>
71 * numbers.c (scm_from_complex_double): Mark as `SCM_UNUSED'.
72 This fixes compilation with `-Werror' on FreeBSD 6.2 (i386).
74 2008-05-05 Neil Jerram <neil@ossau.uklinux.net>
76 * c-tokenize.lex: #define YY_NO_INPUT.
78 2008-04-26 Ludovic Courtès <ludo@gnu.org>
80 * read.c (scm_read_sexp): Remove extraneous semi-colon at
81 end-of-line, which broke compilation with GCC 2.7. Reported by
82 Alain Guibert <alguibert+bts@free.fr>.
84 2008-04-24 Ludovic Courtès <ludo@gnu.org>
86 * Makefile.am (DEFAULT_INCLUDES): New. Fixes compilation on
87 Tru64 where our "random.h" would shadown libc's one.
88 (INCLUDES): Add "-I$(top_buildir)", which is normally in
90 * gen-scmconfig.c: Include <libguile/gen-scmconfig.h>, not
91 "gen-scmconfig.h" since that file is under `$(builddir)'.
93 2008-04-16 Ludovic Courtès <ludo@gnu.org>
95 * ports.c (scm_getc, scm_putc, scm_puts): Moved...
96 * inline.h: ... here. Noticeably improves `read' performance.
98 2008-04-15 Ludovic Courtès <ludo@gnu.org>
99 Julian Graham <joolean@gmail.com>
101 * read.c (scm_keyword_postfix): New.
102 (scm_read_opts): Update docstring for `keywords'.
103 (scm_read_mixed_case_symbol): Add support for postfix keywords.
105 2008-04-13 Ludovic Courtès <ludo@gnu.org>
107 * inline.h (SCM_C_USE_EXTERN_INLINE): New macro. Use it to make
108 sure "extern" declarations are produced when "extern inline" is
109 used. Simplify macrology around inline definitions.
111 2008-04-10 Ludovic Courtès <ludo@gnu.org>
113 * inline.h (SCM_C_EXTERN_INLINE): Special-case Apple's GCC
114 4.0-based compiler, which doesn't support GNU inline semantics
115 at all in C99 mode but doesn't define `__GNUC_STDC_INLINE__'.
116 See http://thread.gmane.org/gmane.network.gnutls.general/1135 .
118 2008-04-10 Andy Wingo <wingo@pobox.com>
120 * struct.c (scm_struct_ref, scm_struct_set_x): "Light" structs
121 have no hidden words (members of the SCM_STRUCT_DATA(x) array
122 accessed with negative indices). In that case, determine the
123 number of fields from the length of the struct layout
124 descriptor. (Most GOOPS instances are light structs.)
126 * goops.c (wrap_init): Initialize 'u' slots to 0, not some random
129 * goops.c (get_slot_value, set_slot_value): In the struct
130 allocation case, don't poke the slots array directly -- we should
131 go through struct-ref/struct-set! code so that we get the
132 permissions and allocation ('u' versus 'p') correct.
134 2008-04-03 Ludovic Courtès <ludo@gnu.org>
136 * inline.h (SCM_C_EXTERN_INLINE): New macro, addresses the
137 "extern inline" semantic change in C99 mode with GCC 4.3 and
138 later and the warning in C99 mode with GCC 4.2. Use it in the
139 inline function definitions.
141 2008-03-24 Neil Jerram <neil@ossau.uklinux.net>
143 Applying patch from Julian Graham, containing minor fixes to his
146 * threads.c (to_timespec): Change 1000000 multiplier to
148 (unchecked_unlock_sym, allow_external_unlock_sym,
149 recursive_sym): Use SCM_SYMBOL.
150 (scm_make_mutex_with_flags): When raising unsupported option
151 error, report what the unsupported option was.
152 (fat_mutex_unlock): When raising errors, unlock m->lock first.
153 (fat_cond_timedwait): Removed.
154 (scm_timed_wait_condition_variable): Call fat_mutex_unlock
155 directly instead of via fat_cond_timedwait.
157 2008-03-10 Ludovic Courtès <ludo@gnu.org>
159 * eval.c, filesys.c: Enclose `alloca' blob in `#ifndef alloca',
160 as per Gnulib's `alloca'. This should fix compilation on
163 2008-03-09 Neil Jerram <neil@ossau.uklinux.net>
165 * numbers.c: Only define scm_from_complex_double if it will
168 2008-03-08 Julian Graham <joolean@gmail.com>
170 * threads.c (scm_join_thread_timed, scm_thread_p,
171 scm_make_mutex_with_flags, scm_lock_mutex_timed,
172 scm_unlock_mutex_timed, scm_mutex_p, scm_condition_variable_p): New
174 (thread_mark): Updated to mark new struct field `mutexes'.

177 (scm_join_thread, scm_make_mutex, scm_make_recursive_mutex,
178 scm_mutex_lock): Reimplement in terms of their newer
180 (scm_abandoned_mutex_error_key): New symbol.
181 (fat_mutex)[unchecked_unlock, allow_external_unlock]: New fields.
182 (fat_mutex_lock): Reimplement to support timeouts and abandonment.
183 (fat_mutex_trylock, scm_try_mutex): Remove fat_mutex_trylock and
184 reimplement scm_try_mutex as a lock attempt with a timeout of zero.
185 (fat_mutex_unlock): Allow unlocking from other threads and unchecked
186 unlocking; implement in terms of condition variable wait.
187 (scm_timed_wait_condition_variable): Reimplement in terms of
189 * threads.h (scm_i_thread)[mutexes]: New field.
190 (scm_join_thread_timed, scm_thread_p, scm_lock_mutex_timed,
191 scm_unlock_mutex_timed, scm_mutex_p, scm_condition_variable_p):
192 Prototypes for new functions.
194 2008-03-06 Ludovic Courtès <ludo@gnu.org>
196 * eval.c (scm_eval): If MODULE_OR_STATE is not a dynamic state,
197 make sure it's a module. Reported by David I. Lehn.
199 2008-03-02 Ludovic Courtès <ludo@gnu.org>
201 * pairs.h (scm_is_pair): Moved declaration to `inline.h'.
202 * inline.h: Make sure `extern' declarations are not produced
203 when `inline' is supported but GCC is not used. This
204 fixes "mixed linkage" errors with compilers such as
207 2008-02-27 Neil Jerram <neil@ossau.uklinux.net>
209 * _scm.h (errno): Remove declarations that have been there
210 forever, and are known to conflict on some platforms with that
211 provided by <errno.h>, which we include unconditionally. If
212 <errno.h> doesn't provide a errno declaration, what is the point
215 2008-02-23 Ludovic Courtès <ludo@gnu.org>
217 * numbers.c (scm_make_rectangular): Rename argument to
218 `real_part' and `imaginary_part' to work around Solaris 2.10
219 headers which define `imaginary' as a macro. Patch by Tim
220 Mooney <mooney@dogbert.cc.ndsu.NoDak.edu>.
222 2008-02-22 Ludovic Courtès <ludo@gnu.org>
224 * read.c (strncasecmp): Add declaration when
225 `HAVE_DECL_STRNCASECMP' is undefined. Fixes compilation on
228 * gc.c (scm_ia64_ar_bsp)[linux]: Don't discard `const' qualifier
231 2008-02-21 Ludovic Courtès <ludo@gnu.org>
235 * goops.c (scm_add_slot): Add `SCM_UNDEFINED' as last argument
236 to `scm_list_n ()'. Thanks to René Köcher
237 <shirk87@googlemail.com>.
239 2008-02-17 Ludovic Courtès <ludo@gnu.org>
241 * script.c (scm_compile_shell_switches): Update copyright year.
243 2008-02-16 Ludovic Courtès <ludo@gnu.org>
245 * gc_os_dep.c: Add NetBSD/alpha support. Patch by Greg Troxel
248 2008-02-12 Ludovic Courtès <ludo@gnu.org>
250 * guile-snarf.in (tempdir): Honor `$TMPDIR'.
252 2008-02-11 Neil Jerram <neil@ossau.uklinux.net>
254 * numbers.c (SCM_COMPLEX_VALUE): Use GUILE_I instead of _Complex_I
255 directly, and only if GUILE_I was defined by the configure step.
256 (scm_log, scm_log10, scm_exp, scm_sqrt): Use SCM_COMPLEX_VALUE
257 code only if SCM_COMPLEX_VALUE is defined.
259 2008-02-07 Ludovic Courtès <ludo@gnu.org>
262 Thanks to David Diffenbaugh <davediff@nbcs.rutgers.edu>.
264 * read.c (scm_read_quote): Don't use `__FUNCTION__' since it is
265 not supported by Sun CC on Solaris 9.
266 (scm_read_keyword): Likewise.
267 * strings.c (scm_take_locale_stringn): Remove
268 `SCM_C_INLINE_KEYWORD' to allow compilation with Sun CC.
270 2008-02-07 Julian Graham <joolean@gmail.com>
272 * threads.c (do_thread_exit, scm_cancel_thread,
273 scm_set_thread_cleanup_x, scm_thread_cleanup): Lock on thread-specific
274 admin mutex instead of `thread_admin_mutex'.
275 * threads.h (scm_i_thread)[admin_mutex]: New field.
276 * throw.c (make_jmpbuf): Don't enter critical section during thread
277 spawn -- there is a possibility of deadlock if other threads are
280 2008-02-06 Neil Jerram <neil@ossau.uklinux.net>
282 * gc-malloc.c (scm_gc_malloc): Return NULL if requested size is 0.
283 (scm_gc_free): Don't call `free' if mem is NULL.
285 2008-02-06 Ludovic Courtès <ludo@gnu.org>
287 * numbers.c (scm_i_mkbig, scm_i_long2big, scm_i_ulong2big,
288 scm_i_clonebig, scm_i_bigcmp, scm_i_dbl2big, scm_i_dbl2num,
289 scm_i_normbig): Remove `SCM_C_INLINE_KEYWORD' since these are
290 declared as `extern' in `numbers.h'. This precluded compilation
291 on Solaris 9 with Sun CC (reported by David Halik
292 <dhalik@nbcs.rutgers.edu>).
294 2008-02-05 Neil Jerram <neil@ossau.uklinux.net>
296 * fports.c (fport_seek): Make dependent on GUILE_USE_64_CALLS.
298 * _scm.h: Make definition of CHOOSE_LARGEFILE depend on
301 2008-02-01 Neil Jerram <neil@ossau.uklinux.net>
303 * modules.c (the_root_module): Moved before scm_current_module.
304 (scm_current_module): Return the root module if `the-module' fluid
307 2008-01-22 Neil Jerram <neil@ossau.uklinux.net>
311 * __scm.h, _scm.h, weaks.c: Update copyright statement to LGPL.
313 2008-01-18 Neil Jerram <neil@ossau.uklinux.net>
315 * hashtab.c (scm_hash_fn_create_handle_x): If supplied assoc_fn
316 returns neither a pair nor #f, signal a wrong-type-arg error.
317 (Thanks to Gregory Marton for reporting this.)
319 2007-12-29 Neil Jerram <neil@ossau.uklinux.net>
321 * gc.c (mark_gc_async): Change "func_data" to "fn_data", to avoid
322 clash with AIX header file.
323 * hooks.c (scm_c_hook_add, scm_c_hook_remove): Same again.
324 * hooks.h (scm_t_c_hook_function, scm_c_hook_add,
325 scm_c_hook_remove): Same again.
327 2007-12-08 Ludovic Courtès <ludo@gnu.org>
329 * __scm.h (SCM_EXPECT, SCM_LIKELY, SCM_UNLIKELY): New macros.
330 (SCM_ASSERT, SCM_ASSERT_TYPE, SCM_ASRTGO, SCM_GASSERT0,
331 SCM_GASSERT1, SCM_GASSERT2, SCM_GASSERTn): Use them.
332 * eval.c (ASSERT_SYNTAX, ASSERT_SYNTAX_2): Likewise.
333 * eval.i.c (CEVAL): Use branch prediction hints for syntax
334 errors, wrong number of arguments and similar.
335 * numbers.c (scm_sum): Use `SCM_LIKELY' for the sum of two
337 (scm_difference, scm_product, scm_i_divide): Likewise.
338 * validate.h (SCM_ASSERT_RANGE): Use `SCM_UNLIKELY'.
340 2007-12-04 Ludovic Courtès <ludo@gnu.org>
342 * ports.c (scm_c_read): Validate PORT as an open input port.
343 (scm_c_write): Validate PORT as an open output port.
345 * socket.c (scm_accept): Leave guile mode using
346 `scm_std_select ()' before calling `accept(2)'. Reported by
349 2007-10-27 Ludovic Courtès <ludo@gnu.org>
351 * fports.c (scm_i_evict_port): Expect a port, rather than a pair
352 containing the port. Fixes a bug in the new port table (2007-08-26).
353 (scm_evict_ports): Use `scm_c_port_for_each ()'.
355 2007-10-21 Neil Jerram <neil@ossau.uklinux.net>
357 * eval.c (unmemoize_delay): Extend the environment before
358 unmemoizing the promise thunk. This fixes a segmentation fault
359 reported by Frank Schwidom.
361 2007-10-20 Julian Graham <joolean@gmail.com>
363 Add support for thread cancellation and user-defined thread
364 cleanup handlers. Small rework by Ludovic Courtès.
366 * null-threads.h (scm_i_pthread_cancel,
367 scm_i_pthread_cleanup_push, scm_i_pthread_cleanup_pop): New.
368 * pthread-threads.h (scm_i_pthread_cancel,
369 scm_i_pthread_cleanup_push, scm_i_pthread_cleanup_pop): New.
370 * scmsigs.c (scm_i_signal_delivery_thread,
371 signal_delivery_thread_mutex): New.
372 (signal_delivery_thread): Leave when `read_without_guile ()'
374 (start_signal_delivery_thread): Acquire SIGNAL_DELIVERY_THREAD
375 before spawning the thread. Initialize
376 SCM_I_SIGNAL_DELIVERY_THREAD.
377 (ensure_signal_delivery_thread): Renamed to...
378 (scm_i_ensure_signal_delivery_thread): this.
379 (scm_i_close_signal_pipe): New.
380 * scmsigs.h: Updated.
381 * threads.c (thread_mark): Mark `t->cleanup_handler'.
382 (guilify_self_1): Initialize `t->cleanup_handler' and
384 (do_thread_exit): Invoke `t->cleanup_handler'.
385 (on_thread_exit): Call `scm_i_ensure_signal_delivery_thread ()'.
386 Call `scm_i_close_signal_pipe ()' when the next-to-last thread
388 (scm_leave_guile_cleanup): New.
389 (scm_i_with_guile_and_parent): Use `scm_i_pthread_cleanup_push ()'
390 and `scm_leave_guile_cleanup ()' to leave guile mode, rather
391 than call `scm_leave_guile ()' after FUNC.
392 (scm_cancel_thread, scm_set_thread_cleanup_x,
393 scm_threads_cleanup): New.
394 (scm_all_threads): Remove SCM_I_SIGNAL_DELIVERY_THREAD from the
396 * threads.h (scm_i_thread)[cleanup_handler, canceled]: New
398 Add declarations of new functions.
400 2007-10-17 Ludovic Courtès <ludo@gnu.org>
402 * read.c (CHAR_IS_BLANK_): Add `\r' (ASCII 0x0d). This fixes a
403 regression compared to 1.8.2. Reported by Puneet
406 2007-10-10 Ludovic Courtès <ludo@gnu.org>
408 * pthread-threads.h (SCM_I_PTHREAD_MUTEX_INITIALIZER): Check
409 `SCM_NEED_BRACES_ON_PTHREAD_MUTEX_INITIALIZER'.
411 (SCM_I_GSC_NEED_BRACES_ON_PTHREAD_MUTEX_INITIALIZER): New.
412 * gen-scmconfig.c (main): Define
413 `SCM_NEED_BRACES_ON_PTHREAD_MUTEX_INITIALIZER'.
415 2007-10-04 Ludovic Courtès <ludo@gnu.org>
417 * i18n.c (scm_make_locale)[!USE_GNU_LOCALE_API]: Don't call
418 `leave_locale_section ()' on failure of
419 `enter_locale_section ()' since the mutex is not held and locale
420 settings are unchanged.
421 (scm_nl_langinfo)[!USE_GNU_LOCALE_API]: Use
422 `restore_locale_settings ()' instead of `leave_locale_section ()'
423 since the mutex is not held.
425 2007-10-02 Ludovic Courtès <ludo@gnu.org>
427 * threads.c (on_thread_exit): Don't call `scm_leave_guile ()'
428 since we're already in non-guile mode. Reported by Greg Toxel
431 2007-10-01 Ludovic Courtès <ludo@gnu.org>
433 * ports.c (flush_output_port): Expect directly a port instead of
434 a pair. Fixes a bug in the new port table (2007-08-26).
436 2007-09-11 Kevin Ryde <user42@zip.com.au>
438 * posix.c (scm_putenv): Confine the putenv("NAME=") bit to mingw, use
439 putenv("NAME") as the fallback everywhere else. In particular this is
440 needed for solaris 9. Reported by Frank Storbeck.
442 2007-09-03 Ludovic Courtès <ludo@gnu.org>
444 * read.c (flush_ws): Handle SCSH block comments.
446 2007-09-03 Ludovic Courtès <ludo@gnu.org>
448 Fix alignment issues which showed up at least on SPARC.
450 * socket.c (scm_t_max_sockaddr, scm_t_getsockopt_result): New.
451 (scm_inet_pton): Change DST to `scm_t_uint32' for correct
453 (scm_getsockopt): Change OPTVAL to `scm_t_getsockopt_result' for
455 (_scm_from_sockaddr): Change ADDRESS to `scm_t_max_sockaddr *'.
456 (scm_from_sockaddr): Cast ADDRESS to `scm_t_max_sockaddr *'.
457 (MAX_SIZE_UN, MAX_SIZE_IN6): Removed.
458 (scm_accept, scm_getsockname, scm_getpeername, scm_recvfrom):
459 Use `scm_t_max_sockaddr' instead of "char max_addr[MAX_ADDR_SIZE]".
461 2007-09-03 Kevin Ryde <user42@zip.com.au>
463 * numbers.c (scm_log): Test HAVE_CLOG as well as HAVE_COMPLEX_DOUBLE
464 before using clog(). It's possible for gcc to provide the "complex
465 double" type, but for the system not to have the complex funcs.
466 (scm_exp): Ditto HAVE_CEXP for cexp().
467 (clog, cexp, carg): Remove fallback definitions. These only
468 duplicated the code within scm_log and scm_exp, and the latter have to
469 exist for the case when there's no "complex double". So better just
470 fix up the conditionals selecting between the complex funcs and plain
471 doubles than worry about fallbacks.
473 2007-09-02 Ludovic Courtès <ludo@gnu.org>
475 * socket.c (scm_make_socket_address): Free C_ADDRESS after use.
476 This fixes a memory leak.
478 2007-08-26 Han-Wen Nienhuys <hanwen@lilypond.org>
480 * fports.c gc-card.c gc.c gc.h ioext.c ports.c ports.h weaks.h
481 gc.c: replace port table with weak hash table. This simplifies
482 memory management, and fixes freed cells appearing in
483 port-for-each output.
485 * init.c (cleanup_for_exit): abort cleanup if init_mutex is still
488 2007-08-23 Ludovic Courtès <ludo@gnu.org>
490 * read.c (scm_read_quote): Record position and copy source
491 expression when asked to. Reported by Kevin.
493 * stime.c: Define `_REENTRANT' only if not already defined.
495 2007-08-21 Kevin Ryde <user42@zip.com.au>
497 * gc-card.c (scm_i_card_statistics): Record scm_tc7_number types as
498 tc16 values so big, real, complex and fraction can be distinguished.
500 (scm_i_tag_name): Return "number" for scm_tc7_number, not NULL. NULL
501 was making numbers come out as "type 23" in gc-live-object-stats.
502 Fix tests of the tc16 number types, they were checked under
503 scm_tc7_number, but the values went down the tag>=255 smob case.
504 Put smob case under scm_tc7_smob instead of using tag>=255, per
505 recommendation in comments with scm_tc7_smob to use symbolic values.
506 Use SCM_TC2SMOBNUM to extract scm_smobs index, instead of explicit
507 code. Lose some unnecessary "break" statements.
509 (scm_i_card_statistics): Use scm_hashq_create_handle_x and modify the
510 element returned, rather than two lookups scm_hashq_ref and
513 2007-08-17 Kevin Ryde <user42@zip.com.au>
515 * stime.c: Add #define _REENTRANT, to get gmtime_r() prototype on
516 solaris 2.6. Reported by anirkko.
518 2007-07-29 Ludovic Courtès <ludo@gnu.org>
520 * Makefile.am (INCLUDES): Added Gnulib includes.
521 (gnulib_library): New.
522 (libguile_i18n_v_@LIBGUILE_I18N_MAJOR@_la_LIBADD): Added
524 (libguile_la_LIBADD): Likewise.
526 * posix.c: Don't define `_GNU_SOURCE' since `gl_EARLY' arranges
527 to define it when available.
528 * srfi-14.c: Likewise.
529 * i18n.c: Likewise. Include Gnulib's <alloca.h>
530 * eval.c: Include Gnulib's <alloca.h>.
531 * filesys.c: Likewise.
532 * read.c: Don't include <strings.h> and don't provide an
533 `strncasecmp ()' replacement; use Gnulib's <string.h> and
534 `strncasecmp ()' instead.
536 2007-07-25 Ludovic Courtès <ludo@gnu.org>
538 * eval.c (macroexp): When `scm_ilength (res) <= 0', return
539 immediately. This used to produce a circular memoized
540 expression, e.g., for `(set (quote x) #t)'.
542 2007-07-22 Ludovic Courtès <ludo@gnu.org>
544 Overhauled the reader, making it faster.
546 * gdbint.c (tok_buf, tok_buf_mark_p): Removed.
547 (gdb_read): Don't use a token buffer. Use `scm_read ()' instead
550 * read.c: Overhauled. No longer use a token buffer. Use a
551 on-stack C buffer in the common case and use Scheme strings when
552 larger buffers are needed.
553 * read.h (scm_grow_tok_buf, scm_flush_ws, scm_casei_streq,
554 scm_lreadr, scm_lreadrecparen): Removed.
555 (scm_i_input_error): Marked as `SCM_NORETURN'.
557 2007-07-15 Ludovic Courtès <ludo@gnu.org>
559 * script.c (scm_compile_shell_switches): Updated copyright year.
561 2007-07-11 Ludovic Courtès <ludo@gnu.org>
563 * goops.c (scm_sys_method_more_specific_p): Added docstring.
564 Make sure LEN is greater than or equal to the minimum length of
565 specializers of M1 and M2. This fixes a segfault later on in
566 `more_specificp ()' if TARGS is too small. Reported by Marco
567 Maggi <marco.maggi-ipsu@poste.it>.
569 2007-06-26 Ludovic Courtès <ludo@gnu.org>
571 * fluids.c (next_fluid_num): When growing ALLOCATED_FLUIDS, make
572 sure to free the previous array after the new one has been
573 installed. This leak is made visible by running
574 "(define l (map (lambda (i) (make-fluid)) (iota 255)))"
575 from the REPL within Valgrind.
577 2007-06-12 Ludovic Courtès <ludo@chbouib.org>
579 * socket.c (scm_inet_ntop): In the `AF_INET' case, declare `addr4'
580 as an `scm_t_uint32' rather than re-using `addr6'. This fixes a
581 bus error on SPARC (and possibly others) due to unaligned access.
583 2007-06-07 Ludovic Courtès <ludovic.courtes@laas.fr>
585 * posix.c (scm_ttyname): Check whether RESULT is NULL before
586 making a string from it (reported by Dan McMahill). Don't call
587 `scm_from_locale_string ()' before the mutex is released.
589 2007-05-26 Ludovic Courtès <ludo@chbouib.org>
591 * eval.c (scm_m_define): Updated comment. Changed order for value
592 evaluation and `scm_sym2var ()' call, which is perfectly valid per
593 R5RS. This reverts the change dated 2004-04-22 by Dirk Herrmann.
595 2007-05-05 Ludovic Courtès <ludo@chbouib.org>
597 Implemented lazy duplicate binding handling.
599 * modules.c (scm_export): Renamed to...
600 (scm_module_export): This. Now public.
601 (module_variable): Removed.
602 (default_duplicate_binding_procedures_var): New variable.
603 (default_duplicate_binding_handlers, resolve_duplicate_binding,
604 module_imported_variable, scm_module_local_variable,
605 scm_module_variable): New functions.
606 (scm_module_import_interface): Rewritten.
607 (scm_module_reverse_lookup): Exported as a Scheme function.
608 * modules.h (scm_module_index_duplicate_handlers,
609 scm_module_index_import_obarray): New macros.
610 (scm_module_variable, scm_module_local_variable,
611 scm_module_export): New declarations.
613 2007-04-17 Ludovic Courtès <ludovic.courtes@laas.fr>
615 * numbers.c: Commented out trailing `HAVE_COMPLEX_DOUBLE' after
616 `#endif'. Use `#ifndef HAVE_XXX' rather than `#if !HAVE_XXX'.
618 2007-04-09 Han-Wen Nienhuys <hanwen@lilypond.org>
620 * numbers.c (carg): provide carg, cexp, clog in case they are
623 2007-03-12 Ludovic Courtès <ludovic.courtes@laas.fr>
625 * i18n.c (scm_nl_langinfo): `#ifdef'd uses of `GROUPING',
626 `FRAC_DIGITS', etc., which are GNU extensions. Reported by
629 2007-03-08 Kevin Ryde <user42@zip.com.au>
631 * struct.c, struct.h (scm_make_vtable): New function, providing
633 * stacks.c (scm_init_stacks): Use it.
635 2007-03-06 Kevin Ryde <user42@zip.com.au>
637 * struct.c (scm_make_struct): Check for R,W,O at end of layout when
638 allocating a tail array. If there's no such then those tail fields
639 are uninitialized and garbage SCMs there can cause a segv if printed
640 (after fetching with struct-ref).
642 2007-02-22 Kevin Ryde <user42@zip.com.au>
644 * scmsigs.c (scm_sleep): In docstring, cross refence usleep.
645 (scm_usleep): Update docstring per manual, cross reference sleep.
647 * struct.c (scm_make_struct): Move SCM_CRITICAL_SECTION_END up so that
648 scm_struct_init is not within that section. scm_struct_init can
649 thrown an error, which within a critical section results in an
652 2007-02-19 Neil Jerram <neil@ossau.uklinux.net>
654 * Makefile.am (noinst_HEADERS): Add private-options.h, so that it
655 is included in the distribution.
656 (noinst_HEADERS): And the same for eval.i.c.
658 2007-01-31 Ludovic Courtès <ludovic.courtes@laas.fr>
660 * i18n.c: Include "libguile/threads.h" and "libguile/posix.h"
661 unconditionally. Include <langinfo.h> and <nl_types.h> when
663 (SCM_I18N_STRINGIFY, SCM_LOCALE_CATEGORY_MASK,
664 SCM_LIST_OR_INTEGER_P): New macros.
665 (LC_*_MASK): When `USE_GNU_LOCALE_API' is undefined, define them
666 as powers of two instead of `(1 << LC_*)'.
667 (scm_i_locale_free): New function/macro.
668 (scm_global_locale): New global variable.
669 (smob_locale_free): Use `scm_i_locale_free ()'.
670 (smob_locale_mark): Check whether the SMOB is `%global-locale'.
671 (get_current_locale_settings): Return `EINVAL' instead of `errno'
672 when `setlocale' fails.
673 (restore_locale_settings): Likewise.
674 (install_locale_categories): Likewise.
675 (install_locale): Likewise. Stop the locale stack traversal when
676 all categories have been handled.
677 (get_current_locale, category_to_category_mask,
678 category_list_to_category_mask): New function.
679 (scm_make_locale): Use them. Accept both lists of `LC_*' values
680 and single `LC_*' values as the first argument. Handle the case
681 where BASE_LOCALE is `%global-locale'. When `USE_GNU_LOCALE_API',
682 duplicate C_BASE_LOCALE before using it.
683 (scm_nl_langinfo, define_langinfo_items): New functions.
684 (scm_init_i18n): When `HAVE_NL_LANGINFO', add feature
685 `nl-langinfo' and invoke `define_langinfo_items ()'.
686 * i18n.h (scm_global_locale, scm_nl_langinfo): New declarations.
687 * posix.c: Include <xlocale.h> when available.
688 (scm_i_locale_mutex): Always define it. Statically initialized.
689 (scm_set_locale): Invoke `scm_i_to_lc_category ()' before
690 acquiring the locale mutex.
691 (scm_init_posix): No longer initialize SCM_I_LOCALE_MUTEX here.
693 2007-01-27 Kevin Ryde <user42@zip.com.au>
695 * ports.c (scm_port_line, scm_set_port_line_x), read.c
696 (scm_i_input_error, scm_lreadr, scm_lreadrecparen): Corrections to
697 port line number type, should be "long" not "int", as per line_number
698 field of scm_t_port. (Makes a difference only on 64-bit systems, and
699 only then for a linenum above 2Gig.)
701 2007-01-25 Han-Wen Nienhuys <hanwen@lilypond.org>
703 * vector.c: remove comment as per kryde's request.
705 2007-01-25 Kevin Ryde <user42@zip.com.au>
707 * sort.c (scm_stable_sort): Return empty list for input empty list, as
708 done in guile 1.6 and as always done by plain `sort'. Was falling
709 through to SCM_WRONG_TYPE_ARG. Reported by Ales Hvezda.
711 2007-01-22 Han-Wen Nienhuys <hanwen@lilypond.org>
713 * vectors.c (s_scm_vector_move_right_x): complain about naming.
715 * srcprop.c: regularize comments.
717 * eval.c: remove superfluous ifndef DEVAL.
719 * private-options.h: idem.
721 * eval.i.c: copyright nitpicking.
723 * eval.c: distangle. move duplicate code to eval.i.c and include
726 * eval.i.c: new file.
728 * backtrace.c, debug.c, debug.h, deprecation.c, eq.c, eval.c
729 eval.h, gsubr.c, init.c, macros.c, print.c, print.h, read.c,
730 read.h, stacks.c, symbols.c, throw.c: use private-options.h
732 * private-options.h: new file: contain hardcoded option
735 * private-gc.h: add FSF header.
737 2007-01-19 Han-Wen Nienhuys <hanwen@lilypond.org>
739 * debug.h (SCM_RESET_DEBUG_MODE): switch to debugging if
740 memoize-symbol is set.
742 * eval.h (SCM_MEMOIZE_HDLR): add macros for memoize symbol trap.
744 * eval.c (CEVAL): add memoize_symbol trap.
746 * options.c (scm_options_try): new function. This allows error
747 reporting before changing options in a critical section.
749 * srcprop.c: use double cell for storing source-properties. Put
750 filename in the plist, and share between srcprops if possible.
751 Remove specialized storage.
753 * srcprop.h: remove macros without SCM_ prefix from
754 interface. Remove specialized storage/type definitions.
760 * eval.c: terminate option lists with 0.
762 * options.c: remove n (for length) from scm_option_X
763 functions. Detect option list length by looking for NULL name.
765 2007-01-19 Ludovic Courtès <ludovic.courtes@laas.fr>
767 * struct.c (scm_i_struct_equalp): Skip comparison if both FIELD1
768 is equal to S1 and FIELD2 is equal to S2. This avoids infinite
769 recursion when comparing `s' fields, as the REQUIRED_VTABLE_FIELDS
770 added by `make-vtable-vtable'. Reported by Marco Maggi.
772 2007-01-18 Han-Wen Nienhuys <hanwen@lilypond.org>
774 * throw.c (scm_ithrow): more refined error message: print symbols
777 2007-01-16 Kevin Ryde <user42@zip.com.au>
779 * feature.c, feature.h (scm_set_program_arguments_scm): New function,
780 implementing `set-program-arguments'.
782 * filesys.c (scm_init_filesys): Use scm_from_int rather than
783 scm_from_long for O_RDONLY, O_WRONLY, O_RDWR, O_CREAT, O_EXCL,
784 O_NOCTTY, O_TRUNC, O_APPEND, O_NONBLOCK, O_NDELAY, O_SYNC and
785 O_LARGEFILE. These are all int not long, per arg to open().
786 (scm_init_filesys): Use scm_from_int rather than scm_from_long for
787 F_DUPFD, F_GETFD, F_SETFD, F_GETFL, F_SETFL, F_GETOWN, F_SETOWN, these
788 are all ints (per command arg to fcntl). Likewise FD_CLOEXEC which is
791 * posix.c (scm_putenv): Correction to "len" variable, was defined only
792 for __MINGW32__ but used under any !HAVE_UNSETENV (such as solaris).
793 Move it to where it's used. Reported by Hugh Sasse.
795 * regex-posix.c (scm_regexp_exec): Remove SCM_CRITICAL_SECTION_START
796 and SCM_CRITICAL_SECTION_END, believe not needed. Their placement
797 meant #\nul in the input (detected by scm_to_locale_string) and a bad
798 flags arg (detected by scm_to_int) would throw from a critical
799 section, causing an abort().
801 * regex-posix.c (scm_init_regex_posix): Use scm_from_int for
802 REG_BASIC, REG_EXTENDED, REG_ICASE, REG_NEWLINE, REG_NOTBOL,
803 REG_NOTEOL; they're all ints not longs (per args to regcomp and
806 2007-01-10 Han-Wen Nienhuys <hanwen@lilypond.org>
808 * throw.c (scm_ithrow): print out key symbol and string arguments
809 when error happens inside a critical section, and document why.
811 2007-01-06 Han-Wen Nienhuys <hanwen@lilypond.org>
813 * read.c (s_scm_read_hash_extend): document #f argument to
816 2007-01-04 Kevin Ryde <user42@zip.com.au>
818 * deprecated.h (scm_create_hook), version.h.in (scm_major_version,
819 scm_minor_version, scm_micro_version, scm_effective_version,
820 scm_version, scm_init_version): Use SCM_API instead of just extern,
821 for the benefit of mingw. Reported by Cesar Strauss.
823 2007-01-03 Han-Wen Nienhuys <hanwen@lilypond.org>
825 * gc.c (s_scm_gc_stats): return an entry for total-cells-allocated
827 (gc_update_stats): update scm_gc_cells_allocated_acc too.
829 2006-12-27 Kevin Ryde <user42@zip.com.au>
831 * threads.c (get_thread_stack_base): In mingw with pthreads we can use
832 the basic scm_get_stack_base. As advised by Nils Durner.
834 * threads.c (get_thread_stack_base): Add a version using
835 pthread_get_stackaddr_np (when available), for the benefit of MacOS.
836 As advised by Heikki Lindholm.
838 * scmsigs.c (signal_delivery_thread): Restrict scm_i_pthread_sigmask
839 to HAVE_PTHREAD_SIGMASK, it doesn't exist on mingw. Reported by Nils
842 2006-12-24 Kevin Ryde <user42@zip.com.au>
844 * posix.c (scm_kill): When only raise() is available, throw an ENOSYS
845 error if pid is not our own process, instead of silently doing nothing.
847 * print.c (scm_write, scm_display, scm_write_char): Disable port close
848 on EPIPE. This was previously disabled but introduction of HAVE_PIPE
849 check in configure.in unintentionally enabled it. Believe that
850 testing errno after scm_prin1 or scm_putc is bogus, a long ago error
851 can leave errno in that state. popen.test "no duplicates" output test
854 2006-12-23 Han-Wen Nienhuys <hanwen@lilypond.org>
856 * numbers.c (scm_i_fraction_reduce): move logic into
857 scm_i_make_ratio(), so fractions are only read.
858 scm_i_fraction_reduce() modifies a fraction when reading it. A
859 race condition might lead to fractions being corrupted by reading
862 Also, the REDUCED bit alters the SCM_CELL_TYPE(), making
863 comparisons between reduced and unreduced fractions go wrong.
865 * numbers.h: remove SCM_FRACTION_SET_NUMERATOR,
866 SCM_FRACTION_SET_DENOMINATOR, SCM_FRACTION_REDUCED_BIT,
867 SCM_FRACTION_REDUCED_SET, SCM_FRACTION_REDUCED_CLEAR,
868 SCM_FRACTION_REDUCED.
870 2006-12-16 Kevin Ryde <user42@zip.com.au>
872 * scmsigs.c (scm_raise): Use raise() rather than kill(), as this is
873 more direct for a procedure called raise.
874 (kill): Remove mingw fake fallback.
876 2006-12-15 Kevin Ryde <user42@zip.com.au>
878 * scmsigs.c: Conditionalize process.h, add io.h believe needed for
881 2006-12-14 Kevin Ryde <user42@zip.com.au>
883 * threads.c (thread_print): Cope with the case where pthread_t is a
884 struct, as found on mingw. Can't just cast to size_t for printing.
885 Reported by Nils Durner.
887 * scmsigs.c: Add <fcntl.h> and <process.h> needed by mingw. Copy the
888 fallback pipe() using _pipe() from posix.c. Reported by Nils Durner.
890 2006-12-13 Kevin Ryde <user42@zip.com.au>
892 * eval.c (scm_m_define): Set 'name procedure property on any
893 scm_procedure_p, not just SCM_CLOSUREP. In particular this picks up
894 procedures with setters as used in srfi-17.
896 * posix.c (scm_crypt): Check for NULL return from crypt(), which the
897 linux man page says is a possibility.
899 2006-12-12 Ludovic Courtès <ludovic.courtes@laas.fr>
901 * libguile/unif.c (read_decimal_integer): Let RESP be SIGN * RES
902 instead of RES (reported by Szavai Gyula). This allows the use of
903 negative lower bounds.
904 (scm_i_read_array): Make sure LEN is non-negative (reported by
907 (scm_array_in_bounds_p): Iterate over S instead of always
908 comparing indices with the bounds of S[0]. This fixes
909 `array-in-bounds?' for arrays with a rank greater than one and
910 with different lower bounds for each dimension.
912 2006-12-05 Kevin Ryde <user42@zip.com.au>
914 * numbers.c (scm_product): For flonum*inum and complex*inum, return
915 exact 0 if inum==0. Already done for inum*flonum and inum*complex,
916 and as per R5RS section "Exactness".
918 2006-12-03 Kevin Ryde <user42@zip.com.au>
920 * Makefile.am (.c.doc): Remove the "test -n" apparently attempting to
921 allow $AWK from the environment to override. It had syntax gremlins,
922 and the presence of a $(AWK) variable set by AC_PROG_AWK in the
923 Makefile stopped it having any effect. Use just $(AWK), which can be
924 overridden with "make AWK=xxx" in the usual way if desired.
926 2006-11-29 Ludovic Courtès <ludovic.courtes@laas.fr>
928 * libguile/vectors.c (scm_vector_to_list): Fixed list
929 construction: elements were not copied when INC is zero (see
930 "shared array" example in `vectors.test'). Reported by
933 2006-11-18 Ludovic Courtès <ludovic.courtes@laas.fr>
935 * Makefile.am (lib_LTLIBRARIES): Added `libguile-i18n-v-XX.la'.
936 (libguile_la_SOURCES): Added `gettext.c', removed `i18n.c'.
937 (libguile_i18n_v_XX_la_SOURCES, libguile_i18n_v_XX_la_CFLAGS,
938 libguile_i18n_v_XX_la_LIBADD, libguile_i18n_v_XX_la_LDFLAGS): New.
939 (DOT_X_FILES): Added `gettext.x'.
940 (DOT_DOC_FILES): Likewise.
941 (EXTRA_libguile_la_SOURCES): Added `locale-categories.h'.
942 (modinclude_HEADERS): Added `gettext.h'.
943 (EXTRA_DIST): Added `libgettext.h'.
945 * gettext.h: Renamed to...
946 * libgettext.h: New file.
948 * i18n.c: Renamed to...
949 * gettext.c: New file.
951 * i18n.h: Renamed to...
952 * gettext.h: New file.
954 * i18n.c, i18n.h, locale-categories.h: New files.
956 * init.c: Include "libguile/gettext.h" instead of
958 (scm_i_init_guile): Invoke `scm_init_gettext ()' instead of
961 * posix.c: Include "libguile/gettext.h" instead of
962 "libguile/i18n.h" Test `HAVE_NEWLOCALE' and `HAVE_STRCOLL_L'.
963 (USE_GNU_LOCALE_API): New macro.
964 (scm_i_locale_mutex): New variable.
965 (scm_setlocale): Lock and unlock it around `setlocale ()' calls.
967 * posix.h: Include "libguile/threads.h".
968 (scm_i_locale_mutex): New declaration.
970 2006-11-17 Neil Jerram <neil@ossau.uklinux.net>
972 * script.c (scm_shell_usage): Note need for subscription to bug-guile@gnu.org.
974 2006-11-08 Ludovic Courtès <ludovic.courtes@laas.fr>
976 * libguile/gc-freelist.c (scm_i_adjust_min_yield): Take two
977 "sweep_stats" arguments; use them instead of accessing the global
978 variables `scm_gc_cells_collected' and `scm_gc_cells_collected_1'.
980 * libguile/gc-segment.c (scm_i_sweep_some_cards): Reset SWEEP
981 before each iteration of the loop.
982 (scm_i_sweep_some_segments): Reset SWEEP at each iteration.
983 (scm_i_get_new_heap_segment): Take an additional argument
984 SWEEP_STATS. Compute MIN_CELLS as a function of it.
986 * libguile/gc.c (scm_gc_cells_collected,
987 scm_gc_cells_collected_1): Removed.
988 (scm_i_gc_sweep_stats, scm_i_gc_sweep_stats_1): New.
989 (scm_gc_cells_marked_acc, scm_gc_cells_swept_acc,
990 scm_gc_time_taken, scm_gc_mark_time_taken, scm_gc_times,
991 scm_gc_cell_yield_percentage, protected_obj_count): Made `static'.
992 (scm_gc_stats): Use `scm_i_gc_sweep_stats' instead of
993 `scm_gc_cells_(collected|swept)'.
994 (gc_update_stats): New.
995 (gc_end_stats): Use `scm_i_gc_sweep_stats' and
996 `scm_i_gc_sweep_stats_1' instead of the former globals.
997 (scm_gc_for_newcell): Invoke `gc_update_stats ()' after each
998 `scm_i_sweep_some_segments' call. This fixes a bug where the GC
999 would keep allocating new segments instead of re-using collected
1000 cells (because `scm_gc_cells_collected' would remain zero).
1002 * libguile/gc.h (scm_gc_cells_swept, scm_gc_cells_collected,
1003 scm_gc_cell_yield_percentage): Removed.
1005 * libguile/private-gc.h (scm_gc_cells_collected_1): Removed.
1006 (scm_i_adjust_min_yield): Updated.
1007 (scm_i_get_new_heap_segment): Updated.
1009 2006-11-02 Neil Jerram <neil@ossau.uklinux.net>
1011 * modules.c: Correct comment saying that low-level environments
1012 will be used "in the next release".
1014 * init.c: Comment out #include of environments.h.
1015 (scm_i_init_guile): Comment out scm_environments_prehistory() and
1016 scm_init_environments() calls.
1018 * Makefile.am (libguile_la_SOURCES): Remove environments.c.
1019 (DOT_X_FILES): Remove environments.x.
1020 (DOT_DOC_FILES): Remove environments.doc.
1021 (modinclude_HEADERS): Remove environments.h.
1023 2006-10-25 Neil Jerram <neil@ossau.uklinux.net>
1025 IA64 HP-UX GC patch from Hrvoje Nikšić. (Thanks!)
1027 * threads.c (SCM_MARK_BACKING_STORE): Use scm_ia64_ar_bsp() and
1028 scm_ia64_register_backing_store_base() instead of Linux-specific
1031 * gc.h (scm_ia64_register_backing_store_base, scm_ia64_ar_bsp):
1034 * gc.c (__libc_ia64_register_backing_store_base): Declaration
1036 (scm_ia64_register_backing_store_base, scm_ia64_ar_bsp): New, with
1037 implementations for Linux and HP-UX.
1039 * coop-pthreads.c (SCM_MARK_BACKING_STORE): Use scm_ia64_ar_bsp()
1040 and scm_ia64_register_backing_store_base() instead of
1041 Linux-specific implementations.
1043 * continuations.h (__libc_ia64_register_backing_store_base):
1044 Declaration removed.
1045 (scm_t_contregs): New "fresh" field.
1047 * continuations.c (ia64_getcontext): Removed.
1048 (scm_make_continuation): Use continuation fresh field instead of
1049 interpreting getcontext return values (which isn't portable). Use
1050 scm_ia64_ar_bsp() and scm_ia64_register_backing_store_base()
1051 instead of Linux-specific implementations.
1052 (copy_stack_and_call): Use scm_ia64_register_backing_store_base()
1053 instead of Linux-specific implementation.
1055 * _scm.h (__ia64__): Also detect __ia64.
1057 2006-10-03 Kevin Ryde <user42@zip.com.au>
1059 * eval.c (SCM_APPLY): For scm_tc7_subr_2o, throw wrong-num-args on 0
1060 arguments or 3 or more arguments. Previously 0 called proc with
1061 SCM_UNDEFINED, and 3 or more silently used just the first 2.
1063 2006-09-28 Kevin Ryde <user42@zip.com.au>
1065 * fports.c, ports.c (ftruncate): Use "HAVE_CHSIZE && ! HAVE_FTRUNCATE"
1066 for chsize fallback, instead of hard-coding mingw. Mingw in fact
1067 supplies ftruncate itself these days.
1069 * ports.c (fcntl.h): Can include this unconditionally, no need for
1072 * ports.c (truncate): Conditionalize on "HAVE_FTRUNCATE && !
1073 HAVE_TRUNCATE" so as not to hard-code mingw. Use "const char *" and
1074 "off_t" for parameters, per usual definition of this function, rather
1075 than "char *" and "int". Use ftruncate instead of chsize. Check for
1076 error on final close.
1078 2006-09-27 Kevin Ryde <user42@zip.com.au>
1080 * numbers.c (scm_log10): Check HAVE_CLOG10, clog10() is not available
1083 * posix.c (scm_execl, scm_execlp, scm_execle): Cast "const char *
1084 const *" for mingw to suppress warnings from gcc (which are errors
1085 under the configure default -Werror). Reported by Nils Durner.
1087 2006-09-26 Kevin Ryde <user42@zip.com.au>
1089 * _scm.h (scm_to_off64_t, scm_from_off64_t): New macros.
1090 * fports.c (scm_open_file): Use open_or_open64.
1091 (fport_seek_or_seek64): New function, adapting fport_seek.
1092 * fports.c, fports.h (scm_i_fport_seek, scm_i_fport_truncate): New
1094 * ports.c (scm_seek, scm_truncate_file): Use scm_i_fport_seek and
1095 scm_i_fport_truncate to allow 64-bit seeks and truncates on fports.
1097 * ports.c (scm_truncate_file): Update docstring per manual.
1099 2006-09-23 Kevin Ryde <user42@zip.com.au>
1101 * numbers.c, numbers.h (scm_log, scm_log10, scm_exp, scm_sqrt): New
1104 2006-09-20 Ludovic Courtès <ludovic.courtes@laas.fr>
1106 * srfi-14.c: Include <config.h>. Define `_GNU_SOURCE'.
1107 (make_predset, define_predset, make_strset, define_strset, false,
1109 (SCM_CHARSET_UNSET, CSET_BLANK_PRED, CSET_SYMBOL_PRED,
1110 CSET_PUNCT_PRED, CSET_LOWER_PRED, CSET_UPPER_PRED,
1111 CSET_LETTER_PRED, CSET_DIGIT_PRED, CSET_WHITESPACE_PRED,
1112 CSET_CONTROL_PRED, CSET_HEX_DIGIT_PRED, CSET_ASCII_PRED,
1113 CSET_LETTER_AND_DIGIT_PRED, CSET_GRAPHIC_PRED, CSET_PRINTING_PRED,
1114 CSET_TRUE_PRED, CSET_FALSE_PRED, UPDATE_CSET): New macros.
1115 (define_charset, scm_srfi_14_compute_char_sets): New functions.
1116 (scm_init_srfi_14): Use `define_charset ()' instead of
1117 `define_predset ()' and `define_strset ()'.
1119 * srfi-14.h (scm_c_init_srfi_14): Removed.
1120 (scm_srfi_14_compute_char_sets): New declaration.
1122 * posix.h: Include "srfi-14.h".
1123 (scm_setlocale): Invoke `scm_srfi_14_compute_char_sets ()' after a
1124 successful `setlocale ()' call.
1126 2006-09-08 Kevin Ryde <user42@zip.com.au>
1128 * socket.c (scm_init_socket): Add MSG_DONTWAIT.
1129 (scm_recvfrom): Update docstring from manual.
1131 2006-08-31 Rob Browning <rlb@defaultvalue.org>
1133 * ports.c (scm_c_port_for_each): Add a
1134 scm_remember_upto_here_1(ports) at the end of the function to fix
1137 2006-08-28 Neil Jerram <neil@ossau.uklinux.net>
1139 * backtrace.c (scm_display_backtrace_with_highlights): Minor
1140 improvements to docstring.
1141 (scm_backtrace_with_highlights): Analogous improvements.
1143 2006-08-12 Kevin Ryde <user42@zip.com.au>
1145 * gen-scmconfig.h.in (SCM_I_GSC_NEED_BRACES_ON_PTHREAD_ONCE_INIT):
1146 New, set from configure.
1147 * gen-scmconfig.c (SCM_NEED_BRACES_ON_PTHREAD_ONCE_INIT): New output
1149 * pthread-threads.h (SCM_I_PTHREAD_ONCE_INIT): Use
1150 SCM_NEED_BRACES_ON_PTHREAD_ONCE_INIT to cope with Solaris.
1151 Reported by Claes Wallin.
1153 2006-08-11 Neil Jerram <neil@ossau.uklinux.net>
1155 * stacks.c (scm_last_stack_frame): Correct docstring (returns a
1156 frame, not a stack).
1158 2006-07-25 Kevin Ryde <user42@zip.com.au>
1160 * threads.c (get_thread_stack_base): Restrict HAVE_PTHREAD_GETATTR_NP
1161 on pthreads version, since pthread_getattr_np not available on solaris
1162 and macos. Reported by Claes Wallin.
1164 2006-07-24 Kevin Ryde <user42@zip.com.au>
1166 * filesys.c (dirfd): Test with #ifndef rather than HAVE_DIRFD, since
1167 it's a macro on MacOS X. Reported by Claes Wallin.
1169 * posix.c (sethostname): Give prototype if not HAVE_DECL_SETHOSTNAME,
1170 for the benefit of Solaris 10. Reported by Claes Wallin.
1172 * socket.c (scm_htonl, scm_ntohl): Use scm_to_uint32 rather than
1173 NUM2ULONG, to enforce 32-bit range check on systems with 64-bit long.
1175 2006-07-21 Kevin Ryde <user42@zip.com.au>
1177 * eval.c, filesys.c (alloca): Update <alloca.h> etc blob, per current
1178 autoconf recommendation. Should fix Solaris 10 reported by Claes
1181 * threads.c: Include <string.h>, needed for memset() which is used by
1182 FD_ZERO() on Solaris 10. Reported by Claes Wallin.
1184 2006-07-18 Rob Browning <rlb@defaultvalue.org>
1186 * continuations.c: Add __attribute__ ((returns_twice)) to the
1187 ia64_getcontext prototype so that gcc will make the right
1188 arrangements and avoid an illegal instruction during
1189 call-with-current-continuation.
1191 2006-07-12 Ludovic Courtès <ludovic.courtes@laas.fr>
1193 * numbers.c (guile_ieee_init): Use regular ANSI C casts rather
1194 than C++-style `X_CAST ()'. Patch posted by by Mike Gran.
1196 2006-07-08 Kevin Ryde <user42@zip.com.au>
1198 * environments.c (core_environments_unobserve): Use if/else rather
1199 than ?: for "SET" bits, avoiding complaints from AIX xlc compiler
1200 about them not being rvalues. Reported by Mike Gran.
1202 * Makefile.am (version.h): Don't use $< in an explicit rule, it's not
1203 portable and in particular fails on OpenBSD and AIX (see autoconf
1204 manual too). Reported by Mike Gran.
1206 2006-06-25 Kevin Ryde <user42@zip.com.au>
1208 * stime.c (bdtime2c): tm_gmtoff is seconds East, so take negative of
1209 tm:gmtoff which is seconds West. Reported by Aaron VanDevender.
1210 (bdtime2c): Test HAVE_STRUCT_TM_TM_GMTOFF for tm_gmtoff, rather than
1212 (scm_strptime): Use tm_gmtoff from the strptime result when that field
1213 exists, it's set by glibc strptime "%s".
1215 2006-06-13 Ludovic Courtès <ludovic.courtes@laas.fr>
1217 * eq.c: Include "struct.h", "goops.h" and "objects.h".
1218 (scm_equal_p): Invoke `scm_i_struct_equalp ()' on structures that
1219 are not GOOPS instances.
1220 * struct.c: Include "eq.h".
1221 (scm_free_structs): Use `SCM_STRUCT_VTABLE_DATA ()' instead of
1223 (scm_i_struct_equalp): New.
1224 * struct.h (scm_i_struct_equalp): New declaration.
1226 2006-06-06 Kevin Ryde <user42@zip.com.au>
1228 * Makefile.am (BUILT_SOURCES): Remove guile.texi, only used by
1229 maintainers (with doc/maint/docstring.el). Fixes parallel "make -j2"
1230 reported by Mattias Holm.
1232 2006-06-03 Kevin Ryde <user42@zip.com.au>
1234 * read.c (s_vector): Conditionalize on SCM_ENABLE_ELISP, to avoid
1235 unused variable warning when elisp disabled. Reported by Ryan
1238 * throw.c (scm_handle_by_message): Add dummy return value to avoid
1239 compiler warning on cygwin. Reported by Ryan VanderBijl.
1241 * Makefile.am (EXTRA_DOT_X_FILES): Typo in dependency rule, was a
1242 duplicate of EXTRA_DOT_DOC_FILES.
1243 (DOT_X_FILES, EXTRA_DOT_X_FILES, DOT_DOC_FILES, EXTRA_DOT_DOC_FILES):
1244 Add scmconfig.h to dependencies, since these all run cpp. Helps a
1245 parallel "make -j2". Reported by Mattias Holm.
1247 2006-05-30 Kevin Ryde <user42@zip.com.au>
1249 * ports.c, ports.h (scm_set_port_mark, scm_set_port_free,
1250 scm_set_port_print, scm_set_port_equalp, scm_set_port_flush,
1251 scm_set_port_end_input, scm_set_port_close, scm_set_port_seek,
1252 scm_set_port_truncate, scm_set_port_input_waiting): Use scm_t_bits for
1253 port type descriptor, same as scm_make_port_type return value.
1255 2006-05-30 Marius Vollmer <mvo@zagadka.de>
1257 * eq.c (scm_equal_p): Use scm_array_equal_p explicitely when one
1258 of the arguments is a array. This allows vectors to be equal to
1259 one-dimensional arrays.
1261 2006-05-29 Marius Vollmer <mvo@zagadka.de>
1263 * throw.c (scm_ithrow): When looking for the jmpbuf, first test
1264 that we have a pair before accessing its cdr. Thanks to Bill
1267 2006-05-28 Kevin Ryde <user42@zip.com.au>
1269 * eval.c, filesys.c: Add malloc.h to get alloca() on mingw. Reported
1272 2006-05-27 Marius Vollmer <mvo@zagadka.de>
1274 * srfi-4.c, strings.c: Replace SCM_C_INLINE with
1275 SCM_C_INLINE_KEYWORD. Thanks to Mark Gran!
1277 2006-05-26 Kevin Ryde <user42@zip.com.au>
1279 * fports.c (fport_input_waiting): For ioctl, check HAVE_IOCTL as well
1280 as defined(FIONREAD), since mingw has FIONREAD but not ioctl().
1281 Reported by "The Senator".
1282 For select and ioctl, move fdes into those conditionals, to avoid
1283 unused variable warning when neither of those used.
1285 2006-05-23 Kevin Ryde <user42@zip.com.au>
1287 * fports.c: Remove "fwrite" declaration under "! HAVE_UNISTD_H".
1288 It's unused and will be in stdio.h anyway (if it's anywhere).
1290 2006-05-20 Kevin Ryde <user42@zip.com.au>
1292 * filesys.c (scm_stat2scm): Test #ifdef S_ISLNK directly, rather than
1293 HAVE_S_ISLNK from configure (it was only a #ifdef test anyway).
1295 * posix.c (scm_mknod): Test #ifdef S_IFLNK before using that (for
1296 symlink). Probably can't create symlinks with mknod anyway though.
1298 * inline.h (scm_is_pair): Add a workaround for i386 gcc 2.95 bad code
1301 2006-05-15 Kevin Ryde <user42@zip.com.au>
1303 * simpos.c, simpos.h (scm_primitive__exit): New function.
1304 (scm_primitive_exit): Update docstring, no longer the best exit after
1307 2006-05-09 Kevin Ryde <user42@zip.com.au>
1309 * numbers.c (scm_i_divide): For big/big wanting inexact, use mpq_get_d
1310 rather than converting to doubles, to avoid inf or nan when the inputs
1311 are too big for a double but the quotient does fit. This affects
1312 conversions exact->inexact of big fractions.
1314 * filesys.c (scm_open_fdes): Use open64.
1315 (scm_init_filesys): Add O_LARGEFILE.
1317 * ports.c (scm_seek): Use lseek64.
1318 (scm_truncate_file): Use ftruncate64.
1320 2006-05-08 Marius Vollmer <mvo@zagadka.de>
1322 * private-gc.h (CELL_P): Also check that the potential pointer is
1323 correctly aligned for a cell. Thanks to Miroslav Lichvar!
1325 2006-04-18 Rob Browning <rlb@defaultvalue.org>
1327 * _scm.h: Add back error if the size of off_t is unknown. The bug
1328 was actually in guile-readline's configuration.
1330 2006-04-18 Kevin Ryde <user42@zip.com.au>
1332 * posix.c (scm_mkstemp): Update docstring from the manual, in
1333 particular file mode 0600 is not guaranteed.
1335 2006-04-17 Kevin Ryde <user42@zip.com.au>
1337 * _scm.h (scm_to_off_t, scm_from_off_t): No error if unknown off_t
1338 size, to help the guile-readline build where off_t is unused.
1340 2006-04-16 Kevin Ryde <user42@zip.com.au>
1342 * filesys.c (scm_stat2scm, scm_stat, scm_lstat): Use stat or stat64.
1343 (scm_readdir): Use readdir64.
1344 (scm_copy_file): Use open64 and fstat64, to cope with >2Gb files.
1345 * ports.c (scm_truncate_file): Use truncate64. Correction truncate
1346 and ftruncate take off_t not size_t.
1347 * _scm.h (stat_or_stat64 etc): Macros for selecting LFS64 when
1350 2006-04-06 Kevin Ryde <user42@zip.com.au>
1352 * fports.c (scm_setvbuf): Fix for not _IOLBF, clear SCM_BUFLINE
1353 instead of toggling it. Reported by Ludovic Courtès.
1355 2006-03-26 Marius Vollmer <mvo@zagadka.de>
1357 * threads.c (get_thread_stack_base): Use scm_get_stack_base
1358 instead of accessing __libc_stack_end directly, and only do this
1359 when pthread_attr_getstack is known not to work for the main
1360 thread or when not using pthreads at all.
1362 * gc_os_dep.c (scm_get_stack_base): Abort when the machine type is
1363 unknown instead of returning NULL.
1365 2006-03-21 Ludovic Courtès <ludovic.courtes@laas.fr>
1367 * numbers.c (scm_i_mem2number): Renamed to
1368 scm_c_locale_stringn_to_number.
1369 * numbers.c, print.c, read.c: Updated callers.
1370 * numbers.h: Update function declaration.
1372 2006-03-11 Neil Jerram <neil@ossau.uklinux.net>
1374 * unif.c (string_set): Don't return in a void function. (Reported
1377 * srfi-4.c (scm_uniform_vector_read_x): Declare base as char*
1378 rather than void*, so we can do pointer arithmetic on it.
1379 (Reported by Mike Gran.)
1380 (s_scm_uniform_vector_write): Ditto.
1382 2006-03-10 Neil Jerram <neil@ossau.uklinux.net>
1384 * unif.c (scm_make_shared_array): Don't use SCM_I_ARRAY_BASE when
1385 oldra is not an array. (Reported by Steve Juranich.)
1387 * threads.c (do_unlock): Renamed from "unlock", which is defined
1388 in unistd.h on QNX. (Reported by Matt Kraai.)
1390 2006-03-04 Kevin Ryde <user42@zip.com.au>
1392 * deprecated.c (scm_i_defer_ints_etc): Show SCM_DEFER_INTS in message,
1393 not SCM_CRITICAL_SECTION_START.
1395 * eval.c, posix.c: Change comments from C++ to C style. Reported by
1398 2006-02-28 Kevin Ryde <user42@zip.com.au>
1400 * unif.c (bitvector_set): Use h->writable_elements not h->elements.
1402 2006-02-26 Kevin Ryde <user42@zip.com.au>
1404 * filesys.c (scm_readdir): Use fpathconf for the dirent size when
1405 NAME_MAX is not available, which is so on Solaris 10. Report and help
1406 by Bill Schottstaedt.
1408 * srfi-13.c (MY_VALIDATE_SUBSTRING_SPEC_UCOPY): New macro.
1409 (scm_string_compare, scm_string_compare_ci, scm_string_lt,
1410 scm_string_gt, scm_string_le, scm_string_ge, scm_string_ci_lt,
1411 scm_string_ci_gt, scm_string_ci_le, scm_string_ci_ge): In comparisons
1412 use "unsigned char", not signed char. This ensures comparisons are
1413 the same as `char<?' etc, and is also the same as guile 1.6 did.
1414 Reported by Sven Hartrumpf.
1416 2006-02-19 Mikael Djurfeldt <mdj@neurologic.cc>
1418 * random.c: Test for SCM_HAVE_T_UINT64 instead of
1420 (scm_i_uniform32, scm_i_uniform32, scm_i_init_rstate): Use
1421 scm_t_uint64 and scm_t_uint32 instead of scm_t_int64 and
1424 2006-01-04 Ludovic Courtès <ludovic.courtes@laas.fr>
1426 * gc-segment.c (scm_i_sweep_some_cards): Take a SWEEP_STATS
1427 argument. Don't refer to SCM_GC_CELLS_COLLECTED and
1428 SCM_CELLS_ALLOCATED. If SEG->FIRST_TIME, let CELLS_COLLECTED as zero.
1429 Take into account SEG->SPAN when computing CELLS_SWEPT.
1430 (scm_i_sweep_segment): Take one more argument, similarly.
1431 (scm_i_sweep_all_segments): Likewise.
1432 (scm_i_sweep_some_segments): Likewise.
1433 (scm_i_adjust_min_yield): Change the way MIN_CELLS is computed: do not
1434 refer to SCM_GC_CELLS_COLLECTED.
1436 * gc-freelist.c (scm_i_adjust_min_yield): Take one more
1437 argument, an `scm_i_sweep_statistics' object.
1438 Change the way DELTA is collected: don't take into account
1439 SCM_GC_CELLS_COLLECTED_1, only SWEEP_STATS.COLLECTED.
1441 * gc-malloc.c (scm_realloc): Pass an extra argument
1442 to `scm_i_sweep_all_segments ()'.
1444 * gc.c (gc_start_stats): Updated accordingly.
1445 (gc_end_stats): Take an additional SWEEP_STATS argument.
1446 Decrement SCM_CELLS_ALLOCATED after calls to `scm_i_sweep_* ()'.
1447 (scm_gc_for_newcell): Updated callers of `scm_i_sweep_*'.
1448 Decrement SCM_CELLS_ALLOCATED.
1449 (scm_i_gc): Likewise.
1451 * private-gc.h (scm_i_sweep_*): Updated function
1452 prototypes accordingly.
1453 (scm_t_sweep_statistics): New type.
1454 (scm_i_sweep_statistics_init): New macro.
1455 (scm_i_sweep_statistics_sum): New macro
1457 2006-02-14 Ludovic Courtès <ludovic.courtes@laas.fr>
1459 * strings.c (scm_i_take_stringbufn): Register LEN+1 bytes instead of
1460 LEN. Without this, too much collectable memory gets unregistered,
1461 which results in an underflow of SCM_MALLOCATED in
1462 `decrease_mtrigger()'.
1464 * gc-malloc.c (decrease_mtrigger): Make sure SIZE is lower than or
1465 equal to SCM_MALLOCATED.
1467 2006-02-13 Marius Vollmer <mvo@zagadka.de>
1469 * eval.c (scm_eval_body): Use scm_i_dynwind_pthread_mutex_lock
1470 oinstead of scm_dynwind_pthread_mutex_lock so that it works when
1471 configured --without-threads.
1472 (SCM_APPLY, CEVAL): Likewise. Thanks to Han-Wen Nienhuys!
1474 2006-02-12 Marius Vollmer <mvo@zagadka.de>
1476 * unif.c (scm_dimensions_to_uniform_array): Use the prototype for
1477 filling when the fill parameter is omitted, as documented, but
1478 turn #\nul into 0 since s8 arrays (signified by a #\nul prototype)
1479 can not store characters.
1481 2006-02-09 Neil Jerram <neil@ossau.uklinux.net>
1483 * socket.c (scm_c_make_socket_address): Pass address_size pointer
1484 on to scm_fill_sockaddr call.
1486 2006-02-04 Neil Jerram <neil@ossau.uklinux.net>
1488 * throw.h (scm_c_catch, scm_c_with_throw_handler,
1489 scm_catch_with_pre_unwind_handler, scm_with_throw_handler): New.
1491 * throw.c (SCM_JBPREUNWIND, SCM_SETJBPREUNWIND): New.
1492 (struct pre_unwind_data): New, replaces struct lazy_catch.
1493 (scm_c_catch): New, replaces scm_internal_catch as the primary
1494 catch API for C code; adds pre-unwind handler support.
1495 (scm_internal_catch): Now just a wrapper for scm_c_catch, for back
1497 (tc16_pre_unwind_data, pre_unwind_data_print,
1498 make_pre_unwind_data, SCM_PRE_UNWIND_DATA_P): Renamed from
1499 "lazy_catch" equivalents.
1500 (scm_c_with_throw_handler): New, replaces scm_internal_lazy_catch
1501 as the primary C API for a "lazy" catch.
1502 (scm_internal_lazy_catch): Now just a wrapper for
1503 scm_c_with_throw_handler, for back compatibility.
1504 (scm_catch_with_pre_unwind_handler): Renamed from scm_catch; adds
1505 pre-unwind handler support.
1506 (scm_catch): Now just a wrapper for
1507 scm_catch_with_pre_unwind_handler, for back compatibility.
1508 (scm_with_throw_handler): New.
1509 (scm_lazy_catch): Update comment to say that the handler can
1510 return, and what happens if it does.
1511 (toggle_pre_unwind_running): New.
1512 (scm_ithrow): When identifying the throw target, take running
1513 flags into account. In general, change naming of things from
1514 "lazy_catch" to "pre_unwind". When throwing to a throw handler,
1515 don't unwind the dynamic context first. Add dynwind framing to
1516 manage the running flag of a throw handler. If a lazy catch or
1517 throw handler returns, rethrow the same exception again. Add
1518 pre-unwind support to the normal catch case (SCM_JMPBUFP).
1520 * root.c (scm_internal_cwdr): Add NULL args to
1521 scm_i_with_continuation_barrier call.
1523 * dynwind.c: Change comment mentioning lazy-catch to mention
1524 pre-unwind data and throw handler also.
1526 * continuations.h (scm_i_with_continuation_barrier): Add
1527 pre-unwind handler args.
1529 * continuations.c (scm_i_with_continuation_barrier): Add
1530 pre-unwind handler args, and pass on to scm_c_catch (changed from
1531 scm_internal_catch).
1532 (c_handler): Remove scm_handle_by_message_noexit call.
1533 (scm_c_with_continuation_barrier): Call
1534 scm_i_with_continuation_barrier with scm_handle_by_message_noexit
1535 as the pre-unwind handler.
1536 (scm_handler): Remove scm_handle_by_message_noexit call.
1537 (s_scm_with_continuation_barrier): Call
1538 scm_i_with_continuation_barrier with scm_handle_by_message_noexit
1539 as the pre-unwind handler.
1541 2006-02-04 Kevin Ryde <user42@zip.com.au>
1543 * gc-mark.c (scm_mark_all): Fix c99-isms "loops" and "again" variables.
1545 2006-02-03 Kevin Ryde <user42@zip.com.au>
1547 * list.c, list.h (scm_list): Restore this function for use from C.
1548 It's a complete no-op but in theory might used by someone.
1550 2006-01-30 Marius Vollmer <mvo@zagadka.de>
1552 * eval.c (scm_eval_body): Lock source_mutex with a dynwind context
1553 so that it gets unlocked in all cases.
1554 (SCM_APPLY, CEVAL): Likewise.
1556 2006-01-29 Marius Vollmer <mvo@zagadka.de>
1558 * ramap.c: (scm_array_map_x): Don't use scm_array_p, use
1559 scm_is_typed_array instead.
1561 Renamed the "frames" that are related to dynamic-wind to "dynamic
1562 contexts. Renamed all functions from scm_frame_ to scm_dynwind_.
1563 Updated documentation.
1567 * futures.h, futures.c: Wrap whole contents in "#if 0"/"#endif".
1568 * eval.c, init.c: Comment out all 'future' related things.
1570 2006-01-28 Marius Vollmer <mvo@zagadka.de>
1572 * inline.h, pairs.c (scm_is_pair): Moved scm_is_pair from pairs.c
1573 to inline.h to make it inline.
1575 2005-12-19 Ludovic Courtès <ludovic.courtes@laas.fr>
1577 * strings.c (scm_i_take_stringbufn): New.
1578 (scm_i_c_take_symbol): New.
1579 (scm_take_locale_stringn): Use `scm_i_take_stringbufn ()'.
1581 * strings.h (scm_i_c_take_symbol): New.
1582 (scm_i_take_stringbufn): New.
1584 * symbols.c (lookup_interned_symbol): New function.
1585 (scm_i_c_mem2symbol): New function.
1586 (scm_i_mem2symbol): Use `lookup_symbol ()'.
1587 (scm_from_locale_symbol): Use `scm_i_c_mem2symbol ()'. This avoids
1588 creating a new Scheme string.
1589 (scm_from_locale_symboln): Likewise.
1590 (scm_take_locale_symbol): New.
1591 (scm_take_locale_symboln): New.
1593 * symbols.h (scm_take_locale_symbol): New.
1594 (scm_take_locale_symboln): New.
1596 2006-01-18 Han-Wen Nienhuys <hanwen@xs4all.nl>
1598 * gc-card.c ("sweep_card"): don't count scm_tc_free_cell for
1601 2005-11-29 Han-Wen Nienhuys <hanwen@xs4all.nl>
1603 * regex-posix.c (s_scm_regexp_exec): list the offending pattern
1606 2005-12-29 Neil Jerram <neil@ossau.uklinux.net>
1608 * fluids.c (next_fluid_num): [From Ludovic Courtès:] Don't trigger
1609 the GC when allocated_fluids_len is zero.
1611 2005-12-14 Neil Jerram <neil@ossau.uklinux.net>
1613 * load.c (the_reader, the_reader_fluid_num): New.
1614 (scm_primitive_load): Support custom reader.
1615 (scm_init_load): Init the_reader and the_reader_fluid_num; export
1616 the_reader as `current-reader'.
1618 * scmsigs.c (do_read_without_guile): Use the "raw_data" passed in
1619 (rather than an uninitialized pointer on the stack).
1621 2005-12-07 Marius Vollmer <mvo@zagadka.de>
1623 Reported by Bruce Korb:
1625 * init.c (invoke_main_func): Don't call exit here. Throws that
1626 are only caught by scm_with_guile will bypass us and would cause
1627 scm_boot_guile to return erroneously.
1628 (scm_boot_guile): Expect scm_with_guile to return and call exit
1629 here, passing it an appropriate exit code.
1633 * script.c (scm_find_executable): Compile fix -- fgetc returns an
1634 unsigned char cast to an int, or -1 for EOS.
1636 2005-12-06 Marius Vollmer <mvo@zagadka.de>
1638 * srfi-4.h, srfi-4.c, srfi-4.i.c (take_uvec): Make BASE pointer
1640 (scm_take_u8vector, etc): Likewise. Thanks to Ludovic Courtès!
1642 * threads.h, threads.c (scm_t_guile_ticket, scm_leave_guile,
1643 scm_enter_guile): Removed from public API. See comment at
1644 scm_without_guile for the rationale.
1646 * scmsigs.c (read_without_guile): New.
1647 (signal_delivery_thread): Use it instead of
1648 scm_leave_guile/read/scm_enter_guile.
1650 From Stephen Compall:
1652 * eval.c (scm_m_cond): Recognize SRFI 61 cond syntax.
1653 (CEVAL): Evaluate SRFI 61 cond clauses.
1655 2005-12-06 Ludovic Courtès <ludovic.courtes@laas.fr>
1657 * gc-card.c (scm_i_card_statistics): Return if BITVEC is NULL.
1658 This was typically hit when running `gc-live-object-stats' right
1659 after starting Guile.
1661 2005-11-30 Kevin Ryde <user42@zip.com.au>
1663 * srfi-13.c (scm_string_append_shared): No copying if just one
1664 non-empty string in args.
1666 2005-11-26 Kevin Ryde <user42@zip.com.au>
1668 * gc-mark.c (scm_mark_all): Change C++ comment to C comment. Reported
1671 * list.c (list): Should be "primitive" in SCM_SNARF_DOCS, not
1674 * random.c (scm_i_copy_rstate, scm_c_make_rstate): Don't test for
1675 scm_malloc returning NULL, it never does that.
1676 * putenv.c (putenv): Likewise.
1678 * socket.c (scm_fill_sockaddr): Remove SCM_C_INLINE_KEYWORD, this is
1679 much too big to want to inline.
1681 2005-11-17 Ludovic Courtès <ludovic.courtes@laas.fr>
1683 * print.c (EXIT_NESTED_DATA): Before popping from the stack, reset
1684 the value at its top. This fixes a reference leak.
1685 (PUSH_REF): Perform `pstate->top++' after calling
1686 `PSTATE_STACK_SET ()' in order to avoid undesired potential side
1689 2005-11-12 Ludovic Courtès <ludovic.courtes@laas.fr>
1691 * gc.c (scm_weak_vectors): Removed.
1693 2005-11-12 Kevin Ryde <user42@zip.com.au>
1695 * socket.c (scm_setsockopt): Missing @defvar in docstring. Reported
1698 2005-11-07 Marius Vollmer <mvo@zagadka.de>
1700 * stime.c (scm_mktime): Use scm_frame_critical_section instead of
1701 SCM_CRITICAL_SECTION_START/END since the code inside the critical
1702 section might exit non-locally.
1704 2005-11-04 Neil Jerram <neil@ossau.uklinux.net>
1706 * eval.c (sym_instead): New symbol.
1707 (ENTER_APPLY): Remove optional use of a continuation when making
1709 (scm_debug_opts): Change doc for 'cheap option to make clear that

1713 and return values using the values that the trap call handlers
1716 * debug.h (SCM_CHEAPTRAPS_P): Removed.
1718 2005-10-27 Ludovic Courtès <ludovic.courtes@laas.fr>
1720 * socket.c (scm_fill_sockaddr): No need to check NULL from scm_malloc.
1721 (scm_connect, scm_bind, scm_sendto): Accept sockaddr object.
1722 (scm_addr_vector): Renamed to _scm_from_sockaddr, update usages.
1723 (scm_from_sockaddr, scm_to_sockaddr, scm_make_socket_address,
1724 scm_c_make_socket_address): New functions.
1725 * socket.h: Add prototypes.
1727 2005-10-24 Kevin Ryde <user42@zip.com.au>
1729 * socket.c (scm_init_socket): Add IPPROTO_IP, IPPROTO_TCP,
1730 IPPROTO_UDP. Remove SOL_IP, SOL_TCP, SOL_UDP. The former are in
1731 POSIX spec examples, the latter are not available on for instance
1734 * socket.c (scm_getsockopt, scm_setsockopt): Update docstrings from
1737 * stime.c (scm_strftime): Update docstring from posix.texi.
1739 2005-10-23 Marius Vollmer <marius.vollmer@uni-dortmund.de>
1741 PTHREAD_RECURSIVE_MUTEX_INITIALIZER_NP is not portable enough.
1743 * null-threads.h, pthread-threads.h
1744 (SCM_I_PTHREAD_RECURSIVE_MUTEX_INITIALIZER): Removed.
1745 (scm_i_pthread_mutexattr_recursive): New.
1747 * threads.c (scm_i_pthread_mutexattr_recursive): Declare.

1750 scm_i_pthread_mutexattr_recursive and scm_i_critical_section_mutex
1753 * eval.c (source_mutex): Do not initialiaze statically.
1754 (scm_init_eval): Do it here, using
1755 scm_i_pthread_mutexattr_recursive.
1757 2005-09-05 Marius Vollmer <mvo@zagadka.de>
1759 * print.h (SCM_PRINT_KEYWORD_STYLE_I, SCM_PRINT_KEYWORD_STYLE):
1762 (scm_print_opts): Added "quote-keywordish-symbols" option.
1763 (quote_keywordish_symbol): New, for evaluating the option.
1764 (scm_print_symbol_name): Use it.
1765 (scm_init_print): Initialize new option to sym_reader.
1767 2005-08-15 Neil Jerram <neil@ossau.uklinux.net>
1769 * eval.c (eval_letrec_inits): New.
1770 (CEVAL): Eval letrec initializer forms using eval_letrec_inits.
1772 2005-08-12 Marius Vollmer <mvo@zagadka.de>
1774 * numbers.c: Use scm_from_bool instead of SCM_BOOL. Thanks to
1777 2005-08-12 Kevin Ryde <user42@zip.com.au>
1779 * srfi-13.c (scm_string_for_each_index): Correction to docstring.
1781 2005-08-06 Kevin Ryde <user42@zip.com.au>
1783 * srfi-13.c (scm_string_any, scm_string_every, scm_string_tabulate,

1785 scm_string_index, scm_string_index_right, scm_string_skip,
1786 scm_string_skip_right, scm_string_count, scm_string_map,
1787 scm_string_map_x, scm_string_for_each, scm_string_for_each_index,
1788 scm_string_filter, scm_string_delete): Use scm_t_trampoline_1 for
1789 procedures called in loops.
1791 2005-08-02 Kevin Ryde <user42@zip.com.au>
1793 * strports.c (st_flush): Increase buffer by 1.5x when growing, to
1794 avoid lots of copying where previoulsy growing by only 80 bytes at a
1797 2005-08-01 Marius Vollmer <mvo@zagadka.de>
1799 * modules.h, modules.c (scm_eval_closure_module): Removed, we
1800 already have scm_lookup_closure_module, which does the same thing.
1802 2005-08-01 Marius Vollmer <mvo@zagadka.de>
1804 New marking algorithm for weak hashtables that fixes the problem
1805 that references from the non-weak value to the associated weak
1806 key (for example) would prevent the entry from ever being dropped.
1808 Guardians have been changed back to their original semantics and
1809 are no longer greedy and no longer drop cycles.
1811 * gc-mark.c (scm_mark_all): Do not rely on hooks to run the weak
1812 hashtable and guardian machinery but call the relevant functions
1815 * guardians.h, guardians.c, deprecated.h,
1816 deprecated.c (scm_destroy_guardian_x, scm_guardian_greedy_p,
1817 scm_guardian_destroyed_p, scm_guard, scm_get_one_zombie):
1818 Deprecated and moved into deprecated.[ch].
1820 * guardians.h, guardians.c: Mostly rewritten.
1821 (scm_i_init_guardians_for_gc,
1822 scm_i_identify_inaccessible_guardeds,
1823 scm_i_mark_inaccessible_guardeds): New.
1824 (scm_make_guardian): Removed greedy_p argument.
1826 * weaks.h, weaks.c (SCM_I_WVECT_TYPE, SCM_I_SET_WVECT_TYPE): New.
1827 (SCM_I_WVECT_N_ITEMS, SCM_I_SET_WVECT_N_ITEMS): New.
1828 (SCM_WVECTF_NOSCAN, SCM_WVECT_NOSCAN_P): Removed.
1829 (scm_weaks_prehistory): Removed.
1830 (scm_i_init_weak_vectors_for_gc, scm_i_mark_weak_vector,
1831 scm_i_mark_weak_vectors_non_weaks,
1832 scm_i_remove_weaks_from_weak_vectors, scm_i_remove_weaks): New.
1833 (scm_weak_vector_gc_init, scm_mark_weak_vector_spines,
1834 scm_scan_weak_vectors): Removed.
1836 * hashtab.h (scm_i_scan_weak_hashtables): New.
1837 * hashtab.c (make_hash_table, scm_i_rehash): Do not use
1839 (hashtable_print): Use SCM_HASHTABLE_N_ITEMS instead of
1841 (scan_weak_hashtables, scm_i_scan_weak_hashtables): Renamed former
1842 to latter. Do not scan the alists themselves, this is done by the
1843 weak vector code now. Just update the element count.
1845 * vectors.h (SCM_I_WVECT_TYPE, SCM_I_WVECT_EXTRA): Renamed former
1846 to latter. The type is now only part of the cell word.
1847 (SCM_I_SET_WVECT_TYPE, SCM_I_SET_WVECT_EXTRA): Likewise.
1849 * init.c (scm_i_init_guile): Do not call scm_weaks_prehistory.
1851 2005-07-18 Mikael Djurfeldt <mdj@d14n36.pdc.kth.se>
1853 Some changes towards making it possible to run Guile on the EM64T
1856 * gc.c (scm_gc_stats): Bugfix: Measure size of the type we are
1857 mallocating for (unsigned long *bounds).
1859 * hashtab.c (scm_i_rehash): Cast SCM_HASHTABLE_FLAGS (table) to
1860 scm_t_bits before storing them in the type word.
1862 * gc.c (tag_table_to_type_alist): Modified type of c_tag from
1865 2005-07-12 Kevin Ryde <user42@zip.com.au>
1867 * eval.c (scm_dbg_make_iloc): Should be SCM_IFRAMEMAX and
1868 SCM_IDISTMAX, and cast uints through scm_t_bits to make gcc happy.
1869 * pairs.c (scm_error_pair_access): Use scm_from_locale_string rather
1870 than scm_makfrom0str.
1871 Reported by Ken Raeburn.
1873 * gc-card.c (scm_dbg_gc_get_bvec): Change return from long* to
1874 scm_t_c_bvec_long*, gcc 4 doesn't like different pointer targets when
1875 returning SCM_GC_CARD_BVEC.
1877 * pairs.c (scm_error_pair_access): Plain ascii ' in error message
1878 rather than latin-1 acute accent, the latter may not print on all
1881 * srfi-13.c (scm_string_filter, scm_string_delete): Strip leading and
1882 trailing deletions, so as to return a substring if those are the only
1885 2005-07-10 Kevin Ryde <user42@zip.com.au>
1887 * socket.c (scm_inet_pton, scm_inet_ntop): Pointer cast to scm_t_uint8
1888 for scm ipv6 funcs, gcc 4 is picky about char* vs uchar*.
1889 (scm_getsockopt, scm_accept, scm_getsockname, scm_getpeername,
1890 scm_recvfrom) Use socklen_t, gcc 4 is picky about int* vs socklen_t*.
1892 2005-07-01 Han-Wen Nienhuys <hanwen@xs4all.nl>
1894 * gc-card.c (scm_i_card_statistics): init tag.
1896 * gc.c (tag_table_to_type_alist): check type of tag. Should be integer.
1898 2005-06-18 Han-Wen Nienhuys <hanwen@xs4all.nl>
1900 * fports.c (s_scm_open_file): add the b flag for binary to the doc
1903 2005-06-25 Kevin Ryde <user42@zip.com.au>
1905 * srfi-13.c (scm_string_filter, scm_string_delete): Partial revert
1906 last change, use plain copy-on-write substrings, the individual
1907 descriptions in the srfi don't mention shared storage (only the
1910 * strings.c (scm_take_locale_stringn): Use realloc to make room for
1911 null-terminator, rather than mallocing a whole new block.
1912 (scm_take_locale_string): Use scm_take_locale_stringn len==-1.
1914 2005-06-12 Marius Vollmer <mvo@zagadka.de>
1916 * ramap.c (scm_array_index_map_x): First test for real arrays,
1917 then check for generalized vectors. This ensures that the
1918 generalized vector case need only work with zero-origin ranges.
1919 (scm_ra_eqp, scm_ra_compare): Use the new array handle functions
1920 to access the target array, making these functions work with all
1921 kinds of arrays, not just bit arrays.
1923 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
1924 gh_list.c, gh_predicates.c: Deprecated everything.
1926 * environments.c (environment_default_folder,
1927 environment_default_observer): Do not use gh_call3, gh_call1.
1929 2005-06-10 Han-Wen Nienhuys <hanwen@xs4all.nl>
1931 * modules.c (s_scm_eval_closure_module): new function. Return the
1932 module inside an eval-closure.
1934 * gc.c (scm_init_storage): make scm_stand_in_procs a weak_key hash
1935 table. This means that procedure properties are GC'd if the
1938 2005-06-11 Kevin Ryde <user42@zip.com.au>
1940 * srfi-13.c (scm_string_filter, scm_string_delete): For char and
1941 charset cases, count chars kept and build a string in a second pass,
1942 rather than using a cons cell for every char kept. Use a shared
1943 substring when nothing removed (such sharing is allowed by the srfi).
1945 2005-06-09 Han-Wen Nienhuys <hanwen@xs4all.nl>
1947 * gc.c (tag_table_to_type_alist): convert tag number to "tag %d"
1948 string, so live object stats can be sorted with string<?.
1950 2005-06-06 Marius Vollmer <mvo@zagadka.de>
1952 * print.c (iprin1): When writing a string, collect all characters
1953 that can be printed directly into one call to scm_lfwrite.
1954 Previously, every character was output with its own call to
1955 write(2) on unbuffered ports.
1957 * eval.c (scm_eval_options_interface): Use
1958 scm_frame_critical_section instead of SCM_CRITICAL_SECTION_START
1959 and SCM_CRITICAL_SECTION_END.
1961 * unif.c (scm_array_in_bounds_p): First test for real arrays, then
1962 check for generalized vectors. This ensures that the generalized
1963 vector case need only work with zero-origin ranges.
1965 2005-06-06 Kevin Ryde <user42@zip.com.au>
1967 * srfi-13.c (scm_string_split): Compare char/char in scan. Mixing an
1968 unsigned int SCM_CHAR and a char string meant an 8-bit char was never
1971 2005-06-05 Marius Vollmer <mvo@zagadka.de>
1973 * eval.c: Added comment on how to make case 1.1 of
1974 r5rs_pitfall.test succeed.
1976 From Jan Nieuwenhuizen <janneke@gnu.org>. Thanks!
1978 * hashtab.h: Bugfix: use SCM_API (WAS: extern).
1980 * socket.c: Remove obsolete comment about socklen_t.
1981 (s_scm_setsockopt)[!HAVE_IP_MREQ]: Do not use ip_mreq code.
1983 * numbers.h (isnan)[__MINGW32__]: Remove.
1985 * Makefile.am (gen_scmconfig_SOURCES): Bugfix: Add
1986 DEFAULT_INCLUDES when cross compiling.
1988 * threads.c (ETIMEDOUT, pipe)[__MINGW32__]: Add defines.
1990 * stime.c (scm_strftime)[!HAVE_TM_ZONE]: Use
1991 SCM_SIMPLE_VECTOR_REF instead of SCM_VELTS. (Changed slightly
1994 2005-05-22 Marius Vollmer <mvo@zagadka.de>
1996 * unif.c (scm_make_shared_array): Add old base to new base since
1997 scm_array_handle_pos does not include the base.

2058 2005-04-25 Kevin Ryde <user42@zip.com.au>
2060 * ramap.c (scm_array_map_x): Allow no source args, add num args checks
2061 to subr_1, subr_2, subr_2o and dsubr cases. No source args only has a
2062 few sensible uses (like filling with a random number generator say),
2063 but has been allowed in the past and so should be kept.
2065 2005-04-23 Kevin Ryde <user42@zip.com.au>
2067 * hashtab.c (scm_hashx_remove_x): Need to pass "closure" to
2068 scm_hash_fn_remove_x.
2070 * list.c (scm_cons_star): Don't modify the rest list, it belongs to
2071 the caller when cons* is reached through apply.
2073 * list.c (list): Use scm_list_copy, so as to produce a fresh list when

2087 * srfi-13.c (scm_string_concatenate, scm_string_concatenate_shared):
2088 Validate list argument, scm_string_append and scm_string_append_shared

2105 * hashtab.h, hashtab.c (scm_hash_fx_remove_x): Removed delete_fn
2106 argument; always use scm_delq_x. The delete_fn function works on
2107 the handle, not the key, and it therefore makes no sense to make

2109 (scm_hashx_remove_x): Likewise. Also, exported to Scheme.
2110 (scm_hash_clear): Accept plain vectors as hashtables.
2111 (scm_delx_x): Removed.

2145 * numbers.c, numbers.h (scm_i_clonebig): Remove static, so can use in
2148 * numbers.c (scm_logior): Must scm_i_normbig results as per scm_logand,
2149 because OR-ing bits into a negative can reduce the value to an inum.
2151 * numbers.c (scm_num_eq_p): On 64-bit systems, be careful about
2152 casting inum to double since that can lose precision.
2154 2005-03-10 Marius Vollmer <marius.vollmer@uni-dortmund.de>

2165 (scm_igc, scm_i_gc): Renamed former to latter. Changed all uses.
2166 Do not lock scm_i_sweep_mutex, which is now non-recursive, or set
2167 scm_gc_running_p. Do not run the scm_after_gc_c_hook.
2168 (scm_gc): Lock scm_i_sweep_mutex, set scm_gc_running_p and run the
2169 scm_after_gc_c_hook here.

2174 * gc-segment.c (scm_i_get_new_heap_segment): Do not check
2177 * gc-malloc.c (scm_realloc, increase_mtrigger): Set
2178 scm_gc_running_p while the scm_i_sweep_mutex is locked.
2180 * inline.h (scm_cell, scm_double_cell): Do not check
2181 scm_gc_running_p, allocation during sweeping is OK.
2183 * gdbint.c (SCM_BEGIN_FOREIGN_BLOCK, SCM_END_FOREIGN_BLOCK): Do
2184 not set scm_block_gc.
2186 * init.c (scm_i_init_guile): Do not set scm_block_gc.

2223 while adding to the global lists.
2226 2005-03-08 Marius Vollmer <mvo@zagadka.de>

2541 documented as a "bitwise operation", and all the rest of those only

3131 Enclosed arrays are now their own smob. This has been done to
3132 make the code more explicit about them and to prepare for the time
3133 when generalized vectors include arbitrary one-dimensional
3134 arrays. (Uptonow, enclosed arrays have been recognized by their
3135 use of an array as their storage 'vector'. When all generalized
3136 vectors are allowed as storage, including one-dimensional arrays,
3137 this will no longer work.)

3181 * ramap.c (cind): Changed second arg to be pointer to long instead
3183 (scm_ramapc): Allocate index vector with scm_malloc and not as
3184 uniform vector. Wrap it in a frame so that it gets properly freed.
3185 (scm_array_index_map_x): Likewise.
3187 * unif.c: Changed all uses of scm_array_prototype to
3188 scm_array_creator. (scm_i_get_old_prototype): Signal error when no

3191 in terms of scm_uniform_vector_read_x and

3404 First cut at integrating uniform vectors from srfi-4 with the rest
3405 of Guile. This change replaces scm_tc7_byvect with a s8 uniform
3406 vector. The plan is to gradually replace one type after the other
3407 until none is left and then to consider general cleanups and

3868 * strop.h, strop.c: Removed, they are now empty.
3869 * Makefile.am: Updated for new and removed files.
3871 * symbols.h, symbols.c (scm_string_ci_to_symbol): Moved here, next
3872 to scm_string_to_symbol.
3874 * chars.c (scm_char_alphabetic_p, scm_char_numeric_p,
3875 scm_char_whitespace_p, scm_upper_case_p, scm_lower_case_p,
3876 scm_char_is_both_p): Use scm_char_set_contains_p with the proper
3877 charset instead of libc functions.
3879 * strorder.c (scm_string_equal_p, scm_string_ci_equal_p,
3880 scm_string_less_p, scm_string_leq_p, scm_string_gr_p,
3881 scm_string_geq_p, scm_string_ci_less_p, scm_string_ci_leq_p,
3882 scm_string_ci_gr_p, scm_string_ci_geq_p): Use scm_string_eq, etc
3883 instead of explicit code.
3885 * deprecated.c, load.c, posix.c, unif.c, symbols.c: Include
3886 "srfi-13.h" instead of "strop.h".
3888 * init.c (scm_init_guile_1): Call scm_init_srfi_13 and
3889 scm_init_srfi_14. Do not call scm_init_strop.

3893 * numbers.c (scm_inf_p): Synced docstring back from manual.
3895 2004-08-22 Marius Vollmer <mvo@zagadka.de>
3897 * strings.c (get_str_buf_start): New helper function.
3898 (scm_i_substring, scm_i_substring_copy, scm_i_substring_shared,
3899 scm_i_string_char, scm_i_string_writable_chars): Use it.
3900 (scm_i_substring_copy): Make START argument optional for C

3918 * eval.c (scm_lookupcar1): Report "Variable used before given a
3919 value" insetad of an "Unbound" one for variables that are found
3920 but still contain SCM_UNDEFINED.
3922 * posix.c (scm_mkstemp): Correction to the correction, mkstemp
3923 expects a null-terminated string in the locale encoding, but
3924 scm_i_string_writable_chars doesn't give that. Fixed by letting
3925 mkstemp modify a locale version of the tmpl argument and copying
3926 the result back into tmpl.
3928 * strop.c (scm_substring_move_x): Store into str2, not str1.
3930 2004-08-20 Kevin Ryde <user42@zip.com.au>

4004 (scm_init_storage): Initialize it.
4005 * gc-malloc.c (descrease_mtrigger, increase_mtrigger): Use it.
4007 * gc-mark.c (scm_gc_mark_dependencies): Call scm_i_string_mark,
4008 scm_i_stringbuf_mark and scm_i_symbol_mark, as appropriate.
4009 * gc-card.c (scm_i_sweep_card): Call scm_i_string_free,
4010 scm_i_stringbuf_free and scm_i_symbol_free, as appropriate.
4012 * strop.c (scm_string_copy): Use scm_c_substring to get a
4013 copy-on-write string.
4015 2004-08-18 Kevin Ryde <user42@zip.com.au>
4017 * arbiters.c (FETCH_STORE): New macro.
4018 (SCM_LOCK_VAL, SCM_UNLOCK_VAL): New constants.

4024 * eq.c (scm_equal_p): Remove real==fraction and fraction==real, they
4025 must be #f according to R5RS. (equal? follows eqv?, and for eqv? an
4026 exact and inexact is #f.)

4029 to get thread safety of scm_ttyname.
4031 * ports.c (ttyname): Remove prototype, unused.
4033 * socket.c (scm_init_socket): Add SOCK_SEQPACKET and SOCK_RDM.
4034 Reported by Michael Tuexen.
4036 2004-08-13 Marius Vollmer <marius.vollmer@uni-dortmund.de>
4038 * load.c (scm_init_load_path): Do not pass NULL to
4039 scm_to_locale_string, which would happen when GUILE_LOAD_PATH is
4040 not set. Thanks to Bill Schottstaedt.

4060 * ioext.c (scm_fdopen): Use scm_i_fdes_to_port together with
4061 scm_i_mode_bits to avoid accessing internals of SCM string from C.
4063 * filesys.c (STRING_SYSCALL, STRING2_SYSCALL): New helper macros.
4064 Use them instead of SCM_SYSCALL when one or two strings need to be
4065 converted into locale strings.
4066 (my_rename): New, gathers platform dependent code for renaming.
4067 (scm_rename): Use it.
4068 (scm_readlink, scm_copy_file): Convert SCM strings to locale
4069 strings instead of accessing their internals.
4070 (scm_basename, scm_dirname): Use SCM_I_STRING_CHARS and
4071 SCM_I_STRING_LENGTH instead of SCM_STRING_CHARS and
4074 * extensions.c (load_extension): Convert lib and init to locale

4084 scm_i_mode_bits to avoid accessing internals of SCM string from C.
4085 * vports.c (scm_make_soft_port): Use scm_i_fdes_to_port together
4086 with scm_i_mode_bits to avoid accessing internals of SCM string
4089 * ports.h (scm_i_mode_bits): New, same as scm_mode_bits but with a
4090 SCM string as argument.
4092 * ports.c (scm_i_void_port): New, like scm_void_port but take mode
4093 bits directly instead of C string.
4094 (scm_void_port): Implement using above.
4095 (scm_sys_make_void_port): Use scm_i_void_port together with
4096 scm_i_mode_bits to avoid accessing internals of SCM string.
4098 * strings.h, strings.c (scm_i_get_substring_spec): New.
4100 * socket.c, rw.c, deprecated.h, validate.h
4101 (SCM_VALIDATE_STRING_COPY): Deprecated. Replaced all uses with
4102 SCM_VALIDATE_STRING plus SCM_I_STRING_CHARS or
4103 scm_to_locale_string, etc.
4104 (SCM_VALIDATE_SUBSTRING_SPEC_COPY): Deprecated. Replaced as
4105 above, plus scm_i_get_substring_spec.

4111 instead of SCM_STRING_CHARS, SCM_STRING_UCHARS, and
4112 SCM_STRING_LENGTH, respectively. Also, replaced scm_return_first
4113 with more explicit scm_remember_upto_here_1, etc, or introduced
4114 them in the first place.
4116 * posix.c (WITH_STRING): New helper macro. Use it where one
4117 locale string is needed for a short piece of code.
4118 (STRING_SYSCALL): New helper macro. Use it instead of SCM_SYSCALL

4127 * load.c (scm_primitive_load_path): Do not check for absolute
4128 filenames when scm_sys_search_load_path returns false, which will
4129 return absolute filenames unchanged.
4131 2004-08-11 Marius Vollmer <mvo@zagadka.de>
4133 * gc.c, procprop.c (scm_init_storage, scm_stand_in_procs,
4134 scm_stand_in_proc): Use a hastable for scm_stand_in_procs instead
4135 of an alist. Thanks to Matthias Koeppe!
4137 2004-08-10 Marius Vollmer <marius.vollmer@uni-dortmund.de>
4139 * strings.h, deprecated.h (SCM_STRING_COERCE_0TERMINATION_X):
4140 Moved from string.h to deprecated.h.
4142 * deprecated.c, deprecated.h (SCM_CHARS, SCM_LENGTH): Removed.
4144 * strings.h, strings.c (SCM_MAKE_STRING_TAG): Renamed to
4145 SCM_I_MAKE_STRING_TAG, changed all uses.
4146 (SCM_STRING_CHARS, SCM_STRING_UCHARS, SCM_STRING_LENGTH): Renamed
4147 to SCM_I_STRING_CHARS, SCM_I_STRING_UCHARS, and SCM_I_LENGTH
4148 respectively. For a short time, the old names are still there as
4149 aliases. Not all uses have been changed yet, but the ones in
4151 (SCM_STRING_MAX_LEN): Do not hardcode to 24 bits, compute from
4153 (scm_is_string, scm_from_locale_string, scm_from_locale_stringn,
4154 scm_take_locale_string, scm_take_locale_stringn,
4155 scm_to_locale_string, scm_to_locale_stringn,
4156 scm_to_locale_stringbuf): New.
4157 (scm_c_string2str, scm_c_substring2str): Deprecated by moving to
4158 deprecated.[hc]. Implemented in terms of the new functions above.
4159 (scm_take_str, scm_take0str, scm_mem2string, scm_str2string,
4160 scm_makfrom0str): Reimplemented in terms of the new functions from
4161 above. They will be discouraged shortly.
4162 (scm_substring): Do not use scm_mem2string.
4163 (scm_i_allocate_string_pointers, scm_i_free_string_pointers): New,
4164 to replace similar code from posix.c, simpos.c, and dynl.c.
4165 (scm_string_append): Use memcpy instead of explicit loop. Do not
4166 use register keyword. Use plain 'char' instead of 'unsigned
4169 * strports.c (scm_mkstrport): Use SCM_I_STRING_UCHARS instead of
4170 SCM_STRING_UCHARS. Use SCM_I_STRINGP instead of SCM_STRINGP.
4172 * strop.c (scm_i_index): Replaced SCM_STRINGP, SCM_STRING_CHARS,
4173 and SCM_STRING_LENGTH with SCM_I_STRINGP, SCM_I_STRING_CHARS, and
4174 SCM_I_STRING_LENGTH, respectively. Pass string object directly,
4175 not as a pointer. Use scm_remember_upto_here_1 to protect it.
4177 * read.c (scm_input_error): Use a SCM value for 'fn', not a C
4178 string. This avoids a conversion round-trip.
4180 * gh_data.c: Replaced SCM_STRINGP, SCM_STRING_CHARS, and
4181 SCM_STRING_LENGTH with SCM_I_STRINGP, SCM_I_STRING_CHARS, and
4182 SCM_I_STRING_LENGTH, respectively.
4183 (gh_scm2newstr): Implement in terms of scm_to_locale_string.
4185 * environments.c: Instead calling scm_puts on the SCM_STRING_CHARS
4186 of a string, call scm_display on the string itself.

4194 Replaced scm_mem2string with scm_from_locale_string.
4196 * simpos.c, posix.c (allocate_string_pointers, environ_list_to_c):
4197 Removed, replaced all uses with scm_i_allocate_string_pointers.
4199 * load.h, load.c (scm_internal_parse_path): Removed.
4200 (scm_parse_path): Use scm_string_split to do the work.
4201 (scm_init_load_path): Use scm_parse_path instead of
4202 scm_internal_parse_path.
4203 (scm_search_path): Rewritten string handling part of the code in
4204 terms of scm_to_locale_stringbuf and so that it is thread safe.
4206 * error.c (scm_error_scm): Throw directly instead of calling
4207 scm_error, this avoids the back and forth conversion of SUBR and
4208 MESSAGE and also plugs a memory leak.
4209 (scm_error): Call scm_error_scm.
4211 * backtrace.c: Replaced SCM_STRINGP with scm_is_string.
4212 (display_header): Print FNAME when it is true, not
4213 merely when it is a string.
4215 * strings.h (SCM_SET_STRING_LENGTH, SCM_SET_STRING_CHARS): Removed
4216 unceremoniously. They were unused by Guile itself, and external
4217 use should stop immediately.
4220 2004-08-10 Marius Vollmer <mvo@zagadka.de>
4222 * numbers.h, number.c, deprecated.h, deprecated.c (scm_round,
4223 scm_truncate): Renamed to scm_c_round and scm_c_truncate;
4224 deprecated versions installed in deprecated.h and deprecated.c.
4227 2004-08-06 Rob Browning <rlb@defaultvalue.org>
4229 * net_db.c (scm_resolv_error): don't cause an exception while
4230 trying to throw an exception -- call scm_misc_error with correct
4231 arguments. The previous arguments needed a format escape that
4232 wasn't in any of the format strings.
4234 2004-08-06 Kevin Ryde <user42@zip.com.au>
4236 * ramap.c (scm_array_fill_x): For byvect char fill, force signed char
4237 so as not to depend on signedness of plain char. For byvect range
4238 check, throw out-of-range rather than wrong-type-arg.
4240 * unif.c (scm_uniform_vector_ref, scm_array_set_x): For byvect, force
4241 signed byte range checks by using scm_to_schar and scm_from_schar,
4242 don't want to depend on signedness of C char.
4244 2004-08-05 Kevin Ryde <user42@zip.com.au>
4246 * arbiters.c (scm_try_arbiter): Use scm_i_misc_mutex instead of
4248 (scm_release_arbiter): Use scm_i_misc_mutex so return value can be
4249 guaranteed if multiple threads compete to unlock.
4250 Update docstrings per doc/ref/api-scheduling.texi.
4252 * filesys.c (scm_copy_file): Use fstat on the input fd rather than
4253 stat on the filename, to be certain a file rename can't mean we get
4254 info on one filesystem object but open another. This fstat usage is
4255 similar to Emacs copy-file.
4257 * posix.c (scm_setgroups): Enhance docstring, per doc/ref/posix.texi.
4259 * simpos.c (scm_system_star): Change scm_from_long to scm_from_int on
4260 SIGINT and SIGQUIT, since those values are ints.
4262 2004-08-03 Marius Vollmer <marius.vollmer@uni-dortmund.de>
4264 * num2integral.i.c, num2float.i.c: Removed.

4276 (scm_make_complex): Discouraged by moving to discouraged.h and
4277 discouraged.c. Replaced all uses with scm_c_make_rectangular.

4280 (scm_is_rational): New.
4281 (scm_i_short2big, scm_i_int2big, scm_i_uint2big, scm_i_size2big,
4282 scm_i_ptrdiff2big, scm_i_long_long2big, scm_i_ulong_long2big):
4284 (scm_make_real, scm_num2dbl, scm_float2num, scm_double2num):
4285 Discouraged by moving to discouraged.h and discouraged.c.
4286 Replaced all uses with scm_from_double.
4287 (scm_num2float, scm_num2double): Discouraged by moving prototype
4288 to discouraged.h and rewriting in terms of scm_to_double.
4289 Replaced all uses with scm_to_double.
4290 (scm_to_double): Do not implement in terms of scm_num2dbl, use
4292 (scm_from_double): Do not implement in terms of scm_make_real, use
4295 2004-08-02 Marius Vollmer <marius.vollmer@uni-dortmund.de>

4300 * gen-scmconfig.c (SCM_ENABLE_DISCOURAGED): Emit based on above.
4302 * eval.c (SCM_EVALIM, SCM_EVALIM2, SCM_XEVAL, SCM_XEVALCAR):
4303 Renamed to SCM_I_* in order to avoid collisions with the versions
4304 defined in deprecated.h.
4306 * discouraged.h, discouraged.c: New files.
4308 * deprecated.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOLP, SCM_EQ_P,
4309 SCM_NEGATE_BOOL, SCM_BOOL, SCM_BOOT_NOT): Promoted from being

4333 and current usage and migration.
4335 2004-07-31 Kevin Ryde <user42@zip.com.au>
4337 * error.c (scm_strerror): Use scm_i_misc_mutex around strerror since
4338 it's not thread safe.
4339 (scm_syserror): Use scm_strerror rather than SCM_I_STRERROR, to take
4341 * fports.c (scm_open_file): Use scm_strerror likewise.

4362 defined in terms of scm_to_signed_integer, etc, but in terms of
4365 * gen-scmconfig.c (SCM_SIZEOF_INTMAX, SCM_SIZEOF_SIZE_T): New.

4392 (scm_to_signed_integer, scm_to_unsigned_integer,
4393 scm_from_signed_integer, scm_from_unsigned_integer): Generate via
4394 conv-integer.i.c and conv-uinteger.i.c, as well.
4396 * number.h (scm_to_ssize_t, scm_to_size_t): Use the new
4397 SCM_I_SSIZE_MIN, SCM_I_SSIZE_MAX, and SCM_I_SIZE_MAX macros for
4398 the limits. Those are always defined.

4415 * deprecated.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOLP, SCM_BOOL):
4416 Reimplement using scm_is_false, scm_is_true, scm_is_bool, and
4417 scm_from_bool, respectively.
4418 (SCM_NINUMP): Added.
4420 * tags.h, deprecated.h (SCM_EQ_P): Deprecated by moving it into
4421 deprecated.h. Replaced all uses with scm_is_eq.

4431 SCM_INUM): Deprecated by renaming them to SCM_I_INUMP,
4432 SCM_I_NINUMP and SCM_I_INUM, respectively and adding deprecated
4433 versions to deprecated.h and deprecated.c. Changed all uses to
4434 either use the SCM_I_ variants or scm_is_*, scm_to_*, or
4435 scm_from_*, as appropriate.
4437 * dynwind.c (scm_i_dowinds): Removed unused code that would call
4438 the unexisting scm_cross_dynwind_binding_scope for inums on the

4443 * socket.c (ipv6_net_to_num, scm_from_ipv6): Renamed
4444 ipv6_net_to_num to scm_from_ipv6, for converting from an IPv6
4445 byte-wise address to a SCM integer. Changed all uses.
4446 (ipv6_num_to_net, scm_to_ipv6): Renamed ipv6_num_to_net to
4447 scm_to_ipv6 and added type and range checking, for converting from
4448 an IPv& byte-wise address to a SCM integer. Changed all uses.
4449 (bignum_in_ipv6_range_p, VALIDATE_INET6): Removed, their function
4450 is now done by scm_to_ipv6.
4452 * numbers.c (scm_to_signed_integer, scm_to_unsigned_integer): dot
4453 not accept inexact integers.
4455 * validate.h, deprecated.h (SCM_VALIDATE_INUM,
4456 SCM_VALIDATE_INUM_COPY, SCM_VALIDATE_BIGINT,
4457 SCM_VALIDATE_INUM_MIN, SCM_VALIDATE_INUM_MIN_COPY,

4459 SCM_VALIDATE_INUM_DEF_COPY, SCM_VALIDATE_INUM_RANGE,
4460 SCM_VALIDATE_INUM_RANGE_COPY): Deprecated because they make the
4461 fixnum/bignum distinction visible. Changed all uses to
4462 scm_to_size_t or similar.
4464 2004-07-09 Marius Vollmer <marius.vollmer@uni-dortmund.de>
4466 * cpp_cnvt.awk: Use scm_from_int instead of SCM_MAKINUM.
4468 2004-07-10 Kevin Ryde <user42@zip.com.au>
4470 * hash.c (scm_hashq, scm_hashv, scm_hash): Restrict to size>=1 rather
4471 than size>=0, since 0<=hash<size cannot be satisfied for size==0, and
4472 such a size causes divide-by-zeros in scm_hasher.
4474 * regex-posix.c (scm_make_regexp): Free rx on error, to avoid memory
4477 2004-07-08 Marius Vollmer <marius.vollmer@uni-dortmund.de>
4479 * numbers.c (scm_is_signed_integer, scm_is_unsigned_integer):
4480 Rewritten using the same logic as scm_to_signed_integer and
4481 scm_to_unsigned_integer, respectively, which is better(tm). Also,
4482 use CHAR_BIT instead of hardcoding 8.
4483 (LLONG_MIN, LLONG_MAX, ULLONG_MAX): Removed and used
4484 SCM_I_LLONG_MIN etc. instead.
4486 * numbers.h (SCM_MAKINUM, SCM_I_MAKINUM): Renamed SCM_MAKINUM to
4487 SCM_I_MAKINUM and changed all uses.
4488 * deprecated.h, deprecated.c (SCM_MAKINUM): Newly deprecated.
4490 * gen-scmconfig.c (SCM_I_LLONG_MIN, SCM_I_LLONG_MAX,
4491 SCM_I_ULLONG_MAX): Instead of hard-coding the numbers, compute
4492 them by assuming twos-complement.
4494 2004-07-07 Marius Vollmer <marius.vollmer@uni-dortmund.de>
4496 * gen-scmconfig.h.in: Added all the new SCM_I_GSC_*_LIMITS that
4497 configure now produces.
4498 * gen-scmconfig.c: Use them to output SCM_T_INT8_MIN, etc
4499 definitions, giving the limits of the integer types defined by
4500 Guile. Also, output a hard coded SCM_I_LLONG_MIN, etc since
4501 LLONG_MIN or LONG_LONG_MIN is hard to get at.
4503 * numbers.h (scm_to_short, scm_to_ushort): It's SHRT_MIN, etc, not
4505 (scm_to_size_t): Use SIZE_MAX instead of cooking our own.
4506 (scm_to_long_long, scm_to_ulong_long, scm_to_int8, scm_to_uint8,

4516 * tags.h (scm_is_eq): New.
4518 * deprecated.h, boolean.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOL,
4519 SCM_NEGATE_BOOL, SCM_BOOLP): Deprecated by moving into
4520 "deprecated.h". Replaced all uses with scm_is_false, scm_is_true,
4521 scm_from_bool, and scm_is_bool, respectively.
4523 * boolean.h (scm_is_bool): Fix bug in prototype.
4524 (scm_from_bool): The argument is "x" not "f", stupid.
4526 * boolean.c (scm_is_bool): Fix typo.
4528 * numbers.h, numbers.c (scm_is_integer, scm_is_signed_integer,

4543 2004-06-27 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4545 * backtrace.c (display_expression, display_frame): Call
4546 scm_i_unmemoize_expr for unmemoizing a memoized object holding a
4547 single memoized expression.
4549 * debug.c (memoized_print): Don't try to unmemoize the memoized
4550 object, since we can't know whether it holds a single expression
4553 (scm_mem_to_proc): Removed check for lambda expression, since it
4554 was moot anyway. Whoever uses these functions for debugging
4555 purposes should know what they do: Creating invalid memoized code
4556 will cause crashes, independent of whether this check is present
4559 (scm_proc_to_mem): Take the closure's code as it is and don't
4560 append a SCM_IM_LAMBDA isym. To allow easier debugging, the
4561 memoized code should not be modified.
4563 * debug.[ch] (scm_unmemoize, scm_i_unmemoize_expr): Removed
4564 scm_unmemoize from public use, but made scm_i_unmemoize_expr
4565 available as a guile internal function instead. However,
4566 scm_i_unmemoize_expr will only work on memoized objects that hold
4567 a single memoized expression. It won't work with bodies.
4569 * debug.c (scm_procedure_source), macros.c (macro_print), print.c
4570 (scm_iprin1): Call scm_i_unmemocopy_body for unmemoizing a body,
4571 i. e. a list of expressions.
4573 * eval.c (unmemoize_exprs): Drop internal body markers from the
4574 output during unmemoization.
4576 * eval.[ch] (scm_unmemocopy, scm_i_unmemocopy_expr,
4577 scm_i_unmemocopy_body): Removed scm_unmemocopy from public use,
4578 but made scm_i_unmemocopy_expr and scm_i_unmemocopy_body available
4579 as guile internal functions instead. scm_i_unmemoize_expr will
4580 only work on a single memoized expression, while
4581 scm_i_unmemocopy_body will only work on bodies.
4583 2004-06-21 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4585 * eval.c (unmemoize_exprs): Handle semi-memoized code.
4587 (scm_cons_source, scm_primitive_eval): Prefer higher level
4588 predicate SCM_FALSEP over SCM_IMP.
4590 2004-06-15 Rob Browning <rlb@defaultvalue.org>
4592 * script.c (scm_shell_usage): minor phrasing change.
4594 * gc_os_dep.c: update ifdefery for macosx.
4595 (scm_get_stack_base): separate result initialization from
4596 declaration to slience warnings with macosx and hp-ux using gcc
4597 3.3. Thanks to Andreas Vögele.
4599 2004-06-13 Han-Wen Nienhuys <hanwen@xs4all.nl>
4601 * eval.c (unmemoize_exprs): use SCM_CONSP for the loop condition.
4603 2004-06-06 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4605 * list.[ch] (scm_i_finite_list_copy): New internal function to
4606 copy lists that are known to be finite (though not necessarily
4609 * debug.c (scm_procedure_source): Don't have scm_unmemocopy treat
4610 a closure's argument list like an expression of a body.
4612 * eval.c (unmemoize_expression, unmemoize_exprs, unmemoize_and,
4613 unmemoize_begin, unmemoize_case, unmemoize_cond, unmemoize_delay,
4614 unmemoize_do, unmemoize_if, unmemoize_lambda, unmemoize_let,
4615 unmemoize_letrec, unmemoize_letstar, unmemoize_or,
4616 unmemoize_set_x, unmemoize_apply, unmemoize_atcall_cc,
4617 unmemoize_at_call_with_values, unmemoize_future, sym_atslot_ref,
4618 unmemoize_atslot_ref, sym_atslot_set_x, unmemoize_atslot_set_x,
4619 unmemoize_builtin_macro): New static functions and symbols.
4621 (scm_unmemocopy): Rewritten in terms of the above. scm_unmemocopy
4622 now has a slightly different meaning: The memoized form that is
4623 receives as its argument is now interpreted as a sequence of
4624 expressions from a body.
4626 (unmemocar, scm_unmemocar): Since the whole functionality of
4627 unmemocar and scm_unmemocar is not needed any more, scm_unmemocar
4628 has its old content back and is deprecated, while unmemocar has
4631 (SCM_BIT7): Removed.
4633 (CEVAL): For unmemoizing a single expression, call
4634 unmemoize_expression instead of scm_unmemocopy, which now expects
4635 a sequence of body expressions. Eliminated unnecessary empty
4636 environment frame when executing let* forms. Eliminated
4637 unmemoization step from evaluator.
4639 2004-06-02 Marius Vollmer <marius.vollmer@uni-dortmund.de>
4641 * eval.c (scm_macroexp, macroexp): Renamed scm_macroexp to
4642 macroexp and made static. Added new version of scm_macroexp that
4643 emits a deprecation warning and then calls macroexp.
4644 (scm_m_undefine): Issue deprecation warning.
4646 2004-05-30 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4648 * eval.c (lookup_global_symbol, literal_p, try_macro_lookup):
4649 Modified to make set! work on symbols that represent syntactic
4652 2004-05-26 Han-Wen Nienhuys <hanwen@xs4all.nl>
4654 * gc.h (SCM_CELL_OBJECT_LOC): use SCM_GC_CELL_OBJECT to prevent
4655 compound expression as lvalue errors.
4657 2004-05-24 Marius Vollmer <mvo@zagadka.de>
4659 * dynwind.c (winder_mark): Use SCM_PACK to correctly convert the
4660 WINDER_DATA to a SCM.
4662 2004-05-24 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4664 * goops.c (compute_getters_n_setters, create_standard_classes,
4665 scm_add_slot): Compute closures by calling scm_i_eval_x on a
4666 lambda expression rather than creating them with scm_closure.
4668 2004-05-22 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4670 * eval.c (s_macro_keyword, scm_m_set_x): Remove checking for
4671 misplaced syntactic keywords. This will not work unless guile's
4672 defmacro feature is deprecated.
4674 (scm_m_case): Fixed a bug that caused the list of labels to grow
4675 with every case form.
4677 2004-05-19 Kevin Ryde <user42@zip.com.au>
4679 * numbers.c (scm_round_number): For inum and big, just return x. For
4680 real, use scm_round for 2^54-1 etc problems covered there.
4682 * numbers.c (trunc): Remove #define to scm_truncate when the C library
4683 doesn't provide trunc. This was for when `truncate' was done as a
4684 scm_tc7_dsubr, no longer required.
4686 * threads.c (scm_threads_mark_stacks) [SCM_STACK_GROWS_UP]: Correction
4687 to stack marking call, two parameters and no cast on t->base.
4689 2004-05-18 Marius Vollmer <mvo@zagadka.de>
4691 * hashtab.c (rehash_after_gc): Bug fix: properly link the
4692 processed hashtables back into the weak_hashtables list. Thanks
4693 to Bill Schottstaedt!
4695 2004-05-16 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4697 * eval.c (unmemoize_quote): New static function.
4699 (scm_m_quote, scm_m_atslot_ref, SCM_CEVAL): Changed the byte code
4700 representation of 'quote' and '@slot-ref' to an improper list.
4701 This reduces execution time, the number of cells used to hold the
4702 memoized code, and thus also reduces garbage collection time.
4704 (scm_unmemocopy): Use unmemoize_quote for quote expressions.
4706 (SCM_CEVAL): Changed macro handling to also work with macros that
4707 return improper lists. Added an assertion, that the code returned
4708 by a macro transformer will not lead to cycles in the memoized
4711 2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4713 No functional change, just rearrangements of functions within the
4716 * eval.c (scm_ilookup, scm_unbound_variable_key,
4717 error_unbound_variable, scm_lookupcar1, scm_lookupcar): Moved to
4718 the definitions used for execution, since that's where they will
4721 2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4723 * numbers.h (SCM_SLOPPY_FRACTIONP): Removed. It was not used
4724 throughout guile, has not been part of an official release yet,
4725 and the concept of sloppy predicates has never been a good idea.
4727 (SCM_FRACTION_NUMERATOR, SCM_FRACTION_DENOMINATOR,
4728 SCM_FRACTION_SET_NUMERATOR, SCM_FRACTION_SET_DENOMINATOR):
4731 2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4733 * throw.c (SETJBJMPBUF, SCM_SETJBDFRAME): Add cast to scm_t_bits
4734 to make explicit what happens.
4736 2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4738 * dynl.c (SET_DYNL_HANDLE): Add cast to scm_t_bits to make
4739 explicit what happens.
4741 * guardians.c (TCONC_IN): Use SCM_SET_CELL_OBJECT_x rather than
4742 SCM_SET_CELL_WORD_x when writing scheme objets to cell elements.
4744 2004-05-11 Marius Vollmer <mvo@zagadka.de>
4746 * scmsigs.c (scm_sigaction_for_thread): Validate that the handler
4747 is indeed a procedure when it isn't a number.
4749 2004-05-10 Marius Vollmer <mvo@zagadka.de>
4751 Convert floating point numbers into strings with an arbitrary
4752 radix. Thanks to Richard Todd!
4754 * numbers.c (FLOBUFLEN): Increase so that radix 2 strings will
4757 (scm_dblprec, fx_per_radix, init_dblprec, init_fx_radix,
4758 number_chars): New, to support variable radices.
4759 (idbl2str): Use above instead of the old base-10 only tables.
4760 (iflo2str): Pass on new RADIX argument to idbl2str.
4761 (scm_number_to_string): Pass radix to iflo2str.
4762 (scm_print_real, scm_print_complex): Explicitly pass radix 10 to
4764 (scm_init_numbers): Call init_dblprec and init_fx_radix for all
4767 2004-05-10 Kevin Ryde <user42@zip.com.au>
4769 * numbers.c (scm_logbit_p): Correction to test above the end of an
4770 inum. Reported by Jan Konecny.
4772 2004-05-06 Marius Vollmer <marius.vollmer@uni-dortmund.de>
4774 * gc.h (scm_t_cell): Fields are now of type SCM instead of
4775 scm_t_bits. Updated all users.
4776 (SCM_GC_CARD_SIZE_MASK): Use SCM_GC_SIZEOF_CARD instead of
4777 duplicating the code.
4778 (SCM_CELL_OBJECT_LOC): New.
4779 (SCM_CARLOC, SCM_CDRLOC): Use it instead of SCM_CELL_WORD_LOC.
4780 (SCM_CELL_WORD_LOC): Moved to "deprecated.h".
4782 * smob.h (SCM_SMOB_DATA_2, SCM_SMOB_DATA_3, SCM_SMOB_FLAGS,
4783 SCM_SET_SMOB_DATA_2, SCM_SET_SMOB_DATA_3, SCM_SET_SMOB_FLAGS,
4784 SCM_SMOB_OBJECT, SCM_SMOB_OBJECT_2, SCM_SMOB_OBJECT_3,
4785 SCM_SET_SMOB_OBJECT, SCM_SET_SMOB_OBJECT_2, SCM_SET_SMOB_OBJECT_3,
4786 SCM_SMOB_OBJECT_LOC, SCM_SMOB_OBJECT_2_LOC,
4787 SCM_SMOB_OBJECT_3_LOC): New.
4788 * smob.c (scm_i_set_smob_flags): New function.
4790 * dynl.c, dynwind.c, eval.h, fluids.h, futures.h, hashtab.h,
4791 hooks.h, keywords.h, macros.h, macros.c, mallocs.c, mallocs.h,
4792 random.h, regex-posix.h, root.h, srcprop.h, srcprop.c, threads.h:
4793 Use SCM_SMOB_* instead of SCM_CELL_* as appropriate. Use
4794 SCM_SMOB_FLAGS and SCM_SET_SMOB_FLAGS instead of accessing the
4795 zeroth word directly. Use SCM_SMOB_PREDICATE as appropriate.
4797 * numbers.h (SCM_I_BIG_MPZ): Use SCM_CELL_OBJECT_LOC instead of
4798 taking the address of SCM_CELL_WORD_1, the latter being no longer
4801 * variable.h (SCM_VARIABLE_LOC): Use SCM_CELL_OBJECT_LOC instead
4802 of casting SCM_CELL_WORD_LOC.
4804 2004-05-02 Kevin Ryde <user42@zip.com.au>
4806 * eval.c (scm_macroexp): Add prototype, since it's not in eval.h under
4807 --disable-deprecated. Reported by Andreas Vögele.
4809 * filesys.c (_POSIX_C_SOURCE): Define to 199506L to get readdir_r (in
4810 particular on HP-UX). Reported by Andreas Vögele.
4812 * list.c (varargs.h): Remove, leave just stdarg.h which is all the
4813 code has support for. Fixes building with AIX cc, which is ansi but
4814 doesn't define __STDC__. Reported by Keith Crane.
4815 (var_start): Remove macro, this variation no longer required.
4816 (scm_list_n): Use va_start directly.
4818 2004-05-01 Kevin Ryde <user42@zip.com.au>
4820 * continuations.c (scm_dynthrow): Use >= instead of SCM_PTR_GE which
4821 is now gone. Reported by Andreas Vögele.
4823 2004-04-28 Kevin Ryde <user42@zip.com.au>
4825 * backtrace.c (display_frame_expr), numbers.c (XDIGIT2UINT,
4826 mem2uinteger, mem2decimal_from_point, mem2ureal): Cast char to int for
4827 ctype.h tests, to avoid warnings from gcc on HP-UX about char as array
4828 subscript. Reported by Andreas Vögele.
4829 Also cast through unsigned char to avoid passing negatives to those
4830 macros if input contains 8-bit values.
4832 * num2integral.i.c (NUM2INTEGRAL): Under non-BIGMPZ_FITSP case,
4833 corrections to range check for signed numbers. Remove
4834 scm_remember_upto_here_1(num) from these checks, since num is used
4835 subsequently anyway.
4837 * num2integral.i.c (NUM2INTEGRAL): Test BIGMPZ_FITSP with "!= 0" to
4838 avoid warning from gcc 3.4. Reported by Hyperdivision.
4840 * numbers.c (scm_bit_extract): Use min instead of MIN.
4841 (MIN): Remove, this conflicts with similar macro defined by limits.h
4842 on HP-UX. Reported by Andreas Vögele.
4844 * stime.c (_POSIX_C_SOURCE): Define to 199506L to get gmtime_r (in
4845 particular on HP-UX). Reported by Andreas Vögele.
4847 * threads.c (scm_threads_mark_stacks): Correction sizet -> size_t.
4848 Reported by Andreas Vögele.
4850 * threads-plugin.h (SCM_MUTEX_MAXSIZE): Increase to 25*sizeof(long),
4851 for the benefit of hpux11 where pthread_mutex_t is 88 bytes. Reported
4854 2004-04-22 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4856 * eval.c (s_macro_keyword): New static identifier.
4858 (scm_m_define): Change order to first create binding and
4859 evaluating the expression afterwards.
4861 (scm_m_set_x): Memoize complete set! expression. Only leave
4862 symbols if no binding exists at memoization time. Throw error if
4863 assigning to a syntactic keyword.
4865 (lazy_memoize_variable): New function.
4867 (CEVAL): When execution set!, perform lazy memoization if
4868 unmemoized symbol is detected.
4870 * modules.c (module_variable): Return variables with unbound
4873 * tags.h: Fix comment.
4875 2004-04-25 Kevin Ryde <user42@zip.com.au>
4877 * chars.c (scm_char_upcase, scm_char_downcase, scm_c_upcase,
4878 scm_c_downcase): Use ctype.h toupper and tolower. This will be useful
4879 in 8-bit locales, and ensures consistency with char-upper-case? and
4880 char-lower-case? which already use ctype.h.
4881 (scm_c_upcase_table, scm_c_downcase_table, scm_lowers, scm_uppers):
4883 * chars.c, chars.h, init.c (scm_tables_prehistory): Remove.
4885 * socket.c (VALIDATE_INET6): Correction to bignum_in_ipv6_range_p
4886 call. Reported by Hyperdivision.
4888 * threads.c (scm_yield): Correction, actually call scm_thread_yield.
4889 Reported by Hyperdivision.
4891 * unif.c (s_scm_make_uve): Remove unused local variable. Reported by
4894 2004-04-22 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4896 Hide the implementation of ilocs and isyms in eval.c.
4898 * deprecated.h (SCM_IFRINC, SCM_ICDR, SCM_IFRAME, SCM_IDIST,
4899 SCM_ICDRP), eval.c (SCM_IFRINC, SCM_ICDR, SCM_IFRAME, SCM_IDIST,
4900 SCM_ICDRP), eval.h (SCM_ICDR, SCM_IFRINC, SCM_IFRAME, SCM_IDIST,
4901 SCM_ICDRP): Deprecated and added to deprecated.h. Moved from
4904 * deprecated.c (scm_isymnames), deprecated.h (scm_isymnames,
4905 SCM_ISYMNUM, SCM_ISYMCHARS), eval.c (SCM_ISYMNUM, isymnames,
4906 scm_unmemocopy, CEVAL), print.c (scm_isymnames), tags.h
4907 (SCM_ISYMNUM, scm_isymnames, SCM_ISYMCHARS): Deprecated
4908 scm_isymnames, SCM_ISYMNUM and SCM_ISYMCHARS and added to
4909 deprecated.[hc]. Moved scm_isymnames from print.c to eval.c and
4910 renamed to isymnames. Moved SCM_ISYMNUM from tags.h to eval.c and
4913 * eval.c (scm_i_print_iloc, scm_i_print_isym), eval.h
4914 (scm_i_print_iloc, scm_i_print_isym), print.c (scm_iprin1):
4915 Extracted printing of ilocs and isyms to guile internal functions
4916 scm_i_print_iloc, scm_i_print_isym of eval.c.
4918 2004-04-22 Kevin Ryde <user42@zip.com.au>
4920 * numbers.c (scm_bit_extract): Use SCM_SRS for signed right shift.
4922 * numbers.c (scm_round): Test for x already an integer, to avoid bad
4923 rounding in x+0.5 when x is a big value already an integer. In
4924 certain hardware rounding cases x+0.5 can give an adjacent integer,
4925 leading to that as the result, when we really just wanted x itself.
4927 2004-04-19 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4929 * eval.c (scm_unmemocopy): Fixed unmemoization of let*.
4931 (deval_args, CEVAL): Minor improvements: Reduced variable scopes,
4932 added const qualifiers, cast intentionally unused expressions to
4933 void for emphasis, improved comment.
4935 2004-04-18 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4937 * tags.h (scm_tags, scm_tc8_tags, scm_tc9_flag, scm_tc8_flag,
4938 scm_tc8_isym): Renamed scm_tags to scm_tc8_tags. Renamed
4939 scm_tc9_flag to scm_tc8_flag. Introduced new identifier
4940 scm_tc8_isym. Defined tc8-tags relative to scm_tc3_imm24.
4941 Defined the tc8-tag for flags to be 0x04, which will mean that
4942 SCM_BOOL_F will also have the value 0x04 instead of 0x013c. Due
4943 to the reduced number of bits and the simpler bit pattern for
4944 SCM_BOOL_F, certain machines may be able to use more efficient
4945 processor instructions to deal with SCM_BOOL_F.
4947 (SCM_ITAG9, SCM_MAKE_ITAG9, SCM_ITAG9_DATA): Removed. These have
4948 never been defined in a released version, thus no need to
4951 (SCM_IFLAGP, SCM_MAKIFLAG, SCM_IFLAGNUM): Flags now use tc8
4952 instead of tc9 tags.
4954 (SCM_ISYMP, SCM_MAKISYM, SCM_ISYMNUM): Isyms now use tc8 instead
4957 (SCM_MAKSPCSYM): Removed. It is almost impossible that user code
4958 could have used this definition.
4960 (SCM_IM_AND, SCM_IM_BEGIN, SCM_IM_CASE, SCM_IM_COND, SCM_IM_DO,
4961 SCM_IM_IF, SCM_IM_LAMBDA, SCM_IM_LET, SCM_IM_LETSTAR,
4962 SCM_IM_LETREC, SCM_IM_OR, SCM_IM_QUOTE, SCM_IM_SET_X): Now encoded
4963 as isyms, as special isyms don't exist any more.
4965 2004-04-18 Kevin Ryde <user42@zip.com.au>
4967 * filesys.c (scm_readdir): Use readdir_r when available, for thread
4970 * numbers.c (scm_max, scm_min): For big/real, use SCM_SWAP rather than
4971 explicit swapping code.
4973 2004-04-15 Kevin Ryde <user42@zip.com.au>
4975 * cpp_sig_symbols.in: Add SIGSYS.
4977 * list.c (scm_append_x): Use iterative style, to avoid non-tail
4980 * numbers.c (scm_max, scm_min): For inum/frac, frac/inum, big/frac,
4981 frac/big and frac/frac, use scm_less_p for exact comparison.
4983 * numbers.c (scm_gcd): For inum/big, use mpz_gcd_ui by sharing code
4986 * numbers.c (xisinf): Add a comment about solaris 7 lacking isinf.
4988 2004-04-06 Han-Wen Nienhuys <hanwen@xs4all.nl>
4990 * inline.h (scm_cell): use SCM_GC_CELL_WORD for checking tag.
4992 * chars.h (scm_init_chars): change scm_{upcase,downcase} to
4993 scm_c_{up,down}case.
4994 (SCM_MAKE_CHAR): add (unsigned char) cast. This prevents havoc
4995 when hi-bit ASCII is subjected to SCM_MAKE_CHAR().
4997 2004-04-06 Kevin Ryde <user42@zip.com.au>
4999 * numbers.c (scm_ash): Remove stray "}" in docstring.
5001 * numbers.c (scm_make_ratio): For inum/bignum integer detection, use
5002 x==SCM_MOST_NEGATIVE_FIXNUM explicitly, for clarity and to avoid
5003 calling mpz_cmp_ui in most cases.
5005 * numbers.c (scm_quotient, scm_remainder): In inum/big, use mpz_cmp_ui
5006 for big == abs(most-negative-fixnum) special case.
5007 (abs_most_negative_fixnum): Remove, no longer used.
5009 * scmsigs.c (scm_sigaction_for_thread): Correction to signum range
5010 test, avoids SCM_VECTOR_REF outside bounds of signal_handlers on
5011 calling (sigaction NSIG).
5013 * simpos.c (scm_system_star): Fix execargv memory leak, merge parent
5014 and fork error cases to do this.
5016 2004-04-03 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
5018 * eval.c (CEVAL): Don't distinguish between short and long
5019 instructions when dispatching - just always dispatch on the
5020 instruction code, which is common for short and long instructions.
5021 Further, removed unnecessary goto statements and added comment.
5023 2004-04-03 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
5025 * eval.c (scm_unmemocopy): Don't distinguish between short and
5026 long instructions when dispatching - just always dispatch on the
5027 instruction code, which is common for short and long instructions.
5028 Further, removed unnecessary goto statements, fixed indentation
5029 and replaced SCM_IMP predicates by SCM_NULLP.
5031 2004-04-03 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
5033 * eval.c (scm_lookupcar1, CEVAL): Use SCM_ILOCP instead of
5034 comparison with SCM_ILOC00. In CEVAL, eliminate goto-label
5037 2004-03-31 Kevin Ryde <user42@zip.com.au>
5039 * simpos.c: Include <signal.h> for SIG_IGN and friends.
5041 2004-03-29 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
5043 Introduce scm_debug_mode_p as a replacement for scm_debug_mode and
5046 * debug.h (scm_debug_mode_p, scm_debug_mode, SCM_DEBUGGINGP),
5047 eval.c (scm_debug_mode_p): Deprecated scm_debug_mode and
5048 SCM_DEBUGGINGP. Provided scm_debug_mode_p instead, to have one
5049 single interface that also matches the naming conventions.
5050 Probably scm_debug_mode_p should be part of the private interface
5053 * debug.h (scm_debug_mode_p), backtrace.c (display_error_body),
5054 eval.c (SCM_APPLY, scm_trampoline_0, scm_trampoline_1,
5055 scm_trampoline_2): Change uses of scm_debug_mode or SCM_DEBUGGINGP
5056 to scm_debug_mode_p.
5059 Deprecate direct access to scm_ceval, scm_deval and scm_ceval_ptr:
5061 * eval.h (scm_ceval, scm_deval, scm_ceval_ptr), debug.h
5062 (scm_ceval_ptr): Deprecated. Moved declaration of scm_ceval_ptr
5063 from debug.h to eval.h.
5065 * debug.h (SCM_RESET_DEBUG_MODE): Don't access scm_ceval_ptr any
5066 more, just leave it with setting scm_debug_mode_p, which is
5067 equivalent for practical purposes.
5069 * deprecated.h (SCM_XEVAL, SCM_XEVALCAR): Call scm_i_eval_x
5070 instead of *scm_ceval_ptr. Leave all evaluating to scm_i_eval_x.
5072 * gdbint.c (gdb_eval): Call scm_i_eval_x instead of scm_ceval.
5074 * eval.c (ceval, deval, scm_ceval, scm_deval): Made scm_ceval
5075 static and renamed it to ceval throughout. Provide a new exported
5076 but deprecated function scm_ceval as a wrapper for backwards
5077 compatibility. The same is done for the deval/scm_deval pair of
5080 * eval.c (CEVAL, SCM_CEVAL): Renamed SCM_CEVAL to CEVAL
5081 throughout. Defined CEVAL to ceval or deval, based on compilation
5084 * eval.c (SCM_XEVAL, SCM_XEVALCAR): Dispatch on scm_debug_mode_p
5085 to ceval and deval instead of calling *scm_ceval_ptr.
5087 * eval.c (dispatching_eval): New deprecated static function.
5089 * eval.c (scm_ceval_ptr): Initialized to dispatching_eval in order
5090 to emulate its old behaviour as closely as possible.
5093 Change the evaluator such that only expressions for which pair? is
5094 true are passed to CEVAL, and such that all other expressions are
5095 evaluated outside of CEVAL:
5097 * eval.c (EVAL): New, provided in analogy to EVALCAR. Evaluate an
5098 expression that is assumed to be memoized already. All but
5099 expressions of the form '(<form> <form> ...)' are evaluated inline
5100 without calling an evaluator.
5102 * eval.c (SCM_XEVAL, SCM_XEVALCAR, EVALCAR): Evaluate all but
5103 expressions of the form '(<form> <form> ...)' inline without
5104 calling an evaluator.
5106 * eval.c (scm_i_eval_x, scm_i_eval, scm_ceval, scm_deval): Handle
5107 the special case of unmemoized symbols passed on the top level.
5109 * eval.c (CEVAL): Change calls to CEVAL to EVAL, except where it
5110 is known that the expression passed to CEVAL is of the form
5111 '(<form> <form> ...)'. Remove handling of the tc7-objects, since
5112 now it is known that the input expression of CEVAL is a pair.
5114 2004-03-29 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
5116 * eval.c (is_self_quoting_p): New static function.
5118 (scm_m_quote): Use is_self_quoting_p.
5120 (copy_tree): Corrected typo in comment.
5122 2004-03-28 Han-Wen Nienhuys <hanwen@xs4all.nl>
5124 * eval.c (s_scm_copy_tree): idem.
5126 * list.c (s_scm_filter): remove "pointer" from doc string.
5128 * gc.h (SCM_GC_CELL_TYPE): SCM_GC_CELL_TYPE uses SCM_GC_CELL_OBJECT.
5130 * goops.h (SCM_NUMBER_OF_SLOTS): don't SCM_UNPACK the result.
5132 * backtrace.c ("display_backtrace_body"): SCM_PACK before SCM_EQ_P
5133 (display_frame): idem.
5134 (display_backtrace_file_and_line): idem.
5136 * tags.h (SCM_UNPACK): stricter typechecking on SCM_UNPACK
5139 2004-03-26 Kevin Ryde <user42@zip.com.au>
5141 * filesys.c (scm_getcwd, scm_readlink): Avoid memory leak on errors.
5143 * numbers.c (scm_modulo): For inum/big and big/big, remove test of
5144 big==0 since that never occurs.
5146 * numbers.c, numbers.h (scm_modulo_expt): Renamed from
5147 scm_modular_expt, matching scheme level name `modulo-expt'.
5149 * numbers.c (scm_modular_expt): Return a negative remainder for a
5150 negative divisor, the same as `modulo' does.
5152 2004-03-26 Eric Hanchrow <offby1@blarg.net>
5154 * numbers.c, numbers.h (scm_modular_expt): New function.
5156 2004-03-25 Kevin Ryde <user42@zip.com.au>
5158 * numbers.c (scm_min, scm_max): Correction to big/real and real/big,
5159 return inexact as required by r5rs.
5161 2004-03-24 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
5163 * eval.c: Separated some definitions relevant for execution from
5164 the memoization part of the file.
5166 (copy_tree): New static function
5168 (scm_copy_tree): Rewritten to fix two kinds or bugs: First, cyclic
5169 structures are detected now and will lead to an exception instead
5170 of forcing guile to run in an endless loop, using up all the
5171 system's memory. Second, arrays in the cdr of an improper list
5172 are now copied. See the new test cases in eval.test.
5174 2004-03-24 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
5176 * posix.c (scm_gethostname): Make sure len is initialised before
5177 it is used. Restructured to (hopefully) represent possible
5178 configurations more clearly in the code. Added unwind handler.
5180 2004-03-23 Kevin Ryde <user42@zip.com.au>
5182 * posix.c (scm_gethostname): Use sysconf(_SC_HOST_NAME_MAX) and/or
5183 MAXHOSTNAMELEN when available.
5185 2004-03-21 Marius Vollmer <mvo@zagadka.de>
5187 * read.c (skip_scsh_block_comment): Also recognize '\r' as a line
5188 terminator. Rewritten the logic as a state machine, I must have
5189 been doing too much VHDL lately...
5191 * eval.c (scm_ceval, scm_deval): Explicitely evaluate ports to
5192 themselves. Thanks to Han-Wen Nienhuys!
5194 * list.c: Changed docstrings so that they no longer talk about
5195 returning 'pointers' to something.
5197 2004-03-20 Han-Wen Nienhuys <hanwen@xs4all.nl>
5199 * gc.c: remove set_debug_cell_accesses! when
5200 SCM_DEBUG_CELL_ACCESSES is not defined. Scheme source code should
5201 use (if (defined? 'set-debug-cell-accesses!) .. ) to switch on
5202 debugging conditionally.
5204 2004-03-21 Kevin Ryde <user42@zip.com.au>
5206 * stime.c (scm_gmtime): Use gmtime_r when available, for thread safety.
5208 2004-03-20 Kevin Ryde <user42@zip.com.au>
5210 * posix.c (scm_gethostname): Preserve errno across free() call.
5212 2004-03-18 Han-Wen Nienhuys <hanwen@xs4all.nl>
5214 * gc-card.c (sweep_card): use SCM_GC_SET_CELL_WORD for setting
5217 2004-03-14 Kevin Ryde <user42@zip.com.au>
5219 * stime.c: Define _GNU_SOURCE for strptime prototype from glibc.
5220 (strptime): Use HAVE_DECL_STRPTIME for when to give own prototype.
5222 2004-03-07 Kevin Ryde <user42@zip.com.au>
5224 * stime.c (scm_gmtime): Return bd_time->tm_zone when available, rather
5226 (filltime): Make zname parameter "const".
5228 2004-03-03 Mikael Djurfeldt <mdj@chunk.mit.edu>
5230 * threads.c, threads.h (scm_c_scm2thread): New function.
5232 2004-02-29 Kevin Ryde <user42@zip.com.au>
5234 * numbers.c (guile_ieee_init): Use C99 INFINITY and NAN when
5235 available. Test HAVE_DINFINITY and HAVE_DQNAN for those globals, in
5236 particular don't assume "defined (__alpha__) && ! defined (linux)"
5237 means OSF. Remove "SCO" code, which was not really SCO specific and
5238 which John W. Eaton advises should be long past being needed.
5240 * posix.c (scm_execl, scm_execlp, scm_execle): Avoid memory leak under
5243 2004-02-24 Kevin Ryde <user42@zip.com.au>
5245 * posix.c (scm_cuserid): Use a private result buffer, for thread safe.
5247 2004-02-22 Kevin Ryde <user42@zip.com.au>
5249 * numbers.c (scm_max, scm_min): For one arg, dispatch to generic for
5250 complex, same as for two args. (Handle only inum, big, real, frac).
5252 2004-02-21 Kevin Ryde <user42@zip.com.au>

5281 * num2integral.i.c (INTEGRAL2BIG): WORDS_BIGENDIAN not right for word
5282 order parameter to mpz_import, in fact with just one word there's no
5283 order to worry about at all.
5285 * numbers.c (scm_num_eq_p): For real==frac, complex==frac, frac==real
5286 and frac==complex, make an exact comparison rather than converting
5287 with fraction2double.
5289 * posix.c, putenv.c, stime.c (environ): Use _NSGetEnviron in Darwin
5290 shared library, since environ is not directly available there.
5292 * script.c (scm_shell_usage): Print to stdout for --help, per GNU
5295 * stime.c (scm_localtime, scm_gmtime, scm_mktime): Provide a default
5296 errno EINVAL in case localtime and gmtime don't set it.
5297 (scm_mktime, scm_strptime): Forcibly use errno EINVAL for our
5298 SCM_SYSERROR, since mktime and strptime generally don't set errno.
5300 2004-02-16 Kevin Ryde <kevin@swox.se>
5302 * gc-malloc.c (scm_done_malloc, scm_done_free): Allow negative sizes,

5313 * unif.c (scm_make_uve): Removed local variable and simplified
5314 code in order to avoid compiler used uninitialized warnings.
5316 * hashtab.c, hashtab.h (scm_hash_map_to_list): Renamed from

5333 input port, note first column is 0, remove shared set-port-line!
5336 * ramap.c (scm_array_fill_x): For fvect and dvect, use scm_num2dbl to
5337 convert args the same way that array-set! does.
5339 * unif.c (scm_make_uve, scm_array_p): Allow fraction 1/3 as prototype
5341 (scm_array_p): Add missing "break"s in switch, fix llvect test look
5342 for "l" not "s", fix dvect to be false for singp(prot) since such a

5355 * read.c (scm_read_opts): New opts `elisp-vectors' and
5358 (scm_lreadr): Use scm_lreadparen1 instead of scm_lreadparen. Make
5359 handling of elisp vector syntax dependent on SCM_ENABLE_ELISP and
5360 `elisp-vectors' option instead of SCM_ELISP_READ_EXTENSIONS.
5361 Allow "\(" and "\)" in strings when SCM_ENABLE_ELISP defined and
5362 `escaped-parens' option set.
5363 (scm_read_token): If elisp vector syntax active, disallow [ and ]
5365 (scm_lreadparen): Rewrite as interface to scm_lreadparen1.

5372 2004-01-23 Han-Wen Nienhuys <hanwen@xs4all.nl>
5374 * eval.c (m_expand_body): remove stray variable new_body.
5376 2004-01-22 Marius Vollmer <mvo@zagadka.de>
5378 * eval.c (m_expand_body): Rewrite the expression in place (by
5379 overwriting FORMS) also when a letrec is constructed, not only
5380 when no definitions are found. Do not return rewritten expression
5381 to emphasize the in-place rewriting. Changed all users.
5383 2004-01-19 Han-Wen Nienhuys <hanwen@xs4all.nl>
5385 * gc.c: add protected_object_count, a number that is dumped from
5388 2004-01-11 Marius Vollmer <mvo@zagadka.de>

5398 changes made to scheme-compound.texi.
5400 2004-01-10 Marius Vollmer <mvo@zagadka.de>
5402 * print.c (scm_print_symbol_name): Handle #{`foo}#, #{,foo}#,
5403 #{.}#, and all numeric strings specially. Thanks to Paul Jarc!
5405 * guile-snarf.in: Use mkdir to create a unique temporary directory
5406 that we can safely use. Thanks to Stefan Nordhausen!
5408 2004-01-07 Marius Vollmer <marius.vollmer@uni-dortmund.de>
5410 * dynwind.h, dynwind.c (scm_i_dowinds): Removed 'explicit'
5411 argument since it is always zero now. Changed all callers.
5412 Removed code for handling fluids.
5414 * fluids.c (scm_c_with_fluids): Use frames instead of adding to
5415 the wind chain explicitely. Use scm_c_with_fluid for the common
5416 case of only one fluid.
5417 (scm_with_fluid): New.
5418 (scm_c_with_fluid): Use frames instead of scm_c_with_fluids.
5420 * fluids.h, fluids.c (scm_frame_fluid): New.

5422 (scm_i_swap_fluids, scm_i_swap_fluids_reverse): Removed.
5424 * dynwind.c (scm_frame_end): Do not use scm_i_dowinds. Instead,
5425 do the unwinding directly. It is simple enough.
5427 * dynwind.h, dynwind.c: Did the following renamings:
5428 scm_begin_frame -> scm_frame_begin,
5429 scm_end_frame -> scm_frame_end,
5430 scm_on_unwind -> scm_frame_unwind,
5431 scm_on_rewind -> scm_frame_rewind,
5432 scm_on_unwind_with_scm -> scm_frame_unwind_with_scm,
5433 scm_on_rewind_with_scm -> scm_frame_rewind_with_scm.
5436 * aync.h, async.c: Did the follwing renamings:
5437 scm_with_blocked_asyncs -> scm_frame_block_asyncs,
5438 scm_with_unblocked_asyncs -> scm_frame_unblock_asyncs.
5441 * ports.h, ports.c: Did the follwing renamings:
5442 scm_with_current_input_port -> scm_frame_current_input_port,
5443 scm_with_current_output_port -> scm_frame_current_output_port,
5444 scm_with_current_error_port -> scm_frame_current_error_port.
5447 2004-01-07 Kevin Ryde <user42@zip.com.au>
5449 * numbers.c (s_bignum): Remove, not used since gmp bignums.
5450 Reported by Richard Todd.
5452 * threads-plugin.h (SCM_MUTEX_MAXSIZE): Increase to 12*sizeof(long),
5453 for the benefit of powerpc-apple-darwin5.5. Reported by Richard Todd.
5455 * unif.c (scm_aind): Test SCM_CONSP rather than !SCM_NULLP while
5456 traversing the args list, fixes segv if an improper list is given.
5457 Reported by Rouben Rostamian.
5459 2004-01-06 Marius Vollmer <marius.vollmer@uni-dortmund.de>
5461 * ports.c (swap_ports, scm_with_current_foo_port): Do not allocate
5462 swap_data on stack, use a 'malloc obj'.
5464 * fluids.h, fluids.c (scm_make_initial_fluids, scm_copy_fluids,
5465 scm_swap_fluids, scm_swap_fluids_reverse): Renamed to
5466 scm_i_... since they are internal. Changed all uses.
5468 * dynwind.c (frame_print): Removed, use the default printer.
5469 (WINDER_F_MARK, WINDER_MARK_P, winder_mark): New.
5470 (scm_on_unwind_with_scm, scm_on_rewind_with_scm): New. Use above
5471 to protect SCM values.
5473 * dynwind.h (SCM_F_WIND_EXPLICITELY,
5474 SCM_F_WIND_EXPLICITLY): It's "explicitly" not "explicitely", damn.
5476 (scm_on_unwind_with_scm, scm_on_rewind_with_scm): New.
5478 2004-01-05 Marius Vollmer <mvo@zagadka.de>

5489 scm_begin_frame, scm_end_frame, scm_on_unwind, scm_on_rewind):
5491 (scm_dowinds, scm_i_dowinds): scm_dowinds has been renamed to
5492 scm_i_dowinds and extended to handle frames and to invoke a 'turn'
5493 function when the outermost wind point has been reached. The
5494 latter is used to copy a continuation stack at the right time.
5495 scm_dowinds remains available.
5496 (SCM_GUARDSP, SCM_BEFORE_GUARD, SCM_AFTER_GUARD, SCM_GUARD_DATA,
5497 tc16_guard, guards_print): Removed.
5498 (scm_internal_dynamic_wind): Reimplemented using frames.

5501 part of copy_stack_and_call.
5502 (copy_stack_and_call): Copy the stack after unwinding and before
5504 (scm_dynthrow): Do not call scm_dowinds, this is now done by
5505 copy_stack_and_call.
5507 2004-01-04 Kevin Ryde <user42@zip.com.au>
5509 * numbers.c (scm_less_p): Don't convert frac to float for compares,
5510 can give bad results due to rounding.
5512 * stime.c (scm_current_time, scm_gettimeofday): Add a comment about
5513 setzone/restorezone protection for DOS.
5515 2003-12-26 Marius Vollmer <mvo@zagadka.de>
5517 * gen-scmconfig.h.in, gen-scmconfig.c: Arrange for scm_t_intmax

5522 * numbers.c (scm_less_p): Remove spurious xisnan from frac+big case.
5524 * numbers.c (scm_make_ratio): Check for numerator equal to
5525 SCM_MOST_NEGATIVE_FIXNUM and bignum denominator the negative of that,
5528 * numbers.c (scm_real_part): Return fraction unchanged rather than
5529 converting to flonum.
5531 2003-11-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
5533 * modules.c (module_variable): Fixed (and thus simplified) the
5534 definition of SCM_BOUND_THING_P to reflect the fact that since
5535 after the 1.4 series of guile, obarrays only hold variable
5538 2003-11-30 Marius Vollmer <mvo@zagadka.de>
5540 * numbers.c (scm_logand): It's "#b...", not "#\b...".
5544 * read.c (scm_lreadr): Signal an error for invalid escape
5545 sequences in strings. Code cleanups too.
5547 * print.c (scm_iprin1): use \xNN hexadecimal sequences when
5548 writing control characters in strings.
5550 2003-11-21 Marius Vollmer <mvo@zagadka.de>
5552 * ports.c (scm_drain_input): Bug fix: only access the port after
5553 checking that it indeed is one.
5555 2003-11-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
5557 * eval.c (s_bad_define): New static identifier.
5559 (m_body): Fixed comment.
5561 (scm_m_define): Don't generate memoized code for definitions that
5562 are not on the top level. As a consequence, no memoized code at
5563 all is generated for definitions any more: Top level definitions
5564 are executed immediately during memoization and internal
5565 definitions are handled separately in m_expand_body.
5567 (scm_unmemocopy, unmemocopy): Removed code for unmemoizing
5568 definitions. Consequently, there is no unmemoizing code any more
5569 that might modify the environment. Thus, the old scm_unmemocopy
5570 is removed and the old unmemocopy is renamed to scm_unmemocopy.
5572 (SCM_CEVAL): The SCM_IM_DEFINE keyword can no longer occur in
5573 memoized code. Call EVALCAR for continuations. Prefer !SCM_NULLP
5574 over SCM_NIMP in places, where the argument is known to be part of
5577 2003-11-21 Kevin Ryde <user42@zip.com.au>
5579 * numbers.c (scm_abs): Allocate a new real only for negatives, as done
5582 * numbers.c (scm_bit_extract): Use mpz functions, rearrange inum case
5583 to share some shifting.
5585 * numbers.c (scm_integer_expt): Don't mpz_init after scm_i_clonebig or
5586 scm_i_mkbig, since they do so already. Don't mpz_clear a bignum SCM,
5589 2003-11-19 Marius Vollmer <mvo@zagadka.de>
5591 * numbers.c (scm_make_ratio): Rewritten to have a simpler
5592 structure. Previously, not all cases with a negative denominator
5595 * numbers.c (mem2decimal_from_point): use scm_divide instead of
5596 scm_divide2real when forming the fractional part. This allows
5597 "#e1.2" to yield 6/5.
5599 * numbers.c (scm_i_fraction_equalp): Do not treat the return value
5600 of scm_equal_p as a C boolean, use SCM_FALSEP. Previously, all
5601 fractions were equal to each other regardless of value. Ooops.
5603 * numbers.c (scm_rationalize): Return an inexact result when given
5606 * numbers.c (scm_exact_p, scm_inexact_p): Throw error for

5624 (scm_round_number, scm_truncate_number, scm_ceiling, scm_floor):
5625 New exact functions that replace the inexact 'dsubr'
5627 (scm_numerator, scm_denominator): New.
5629 * numbers.h (SCM_NUMP): Recognize fractions.
5630 (SCM_FRACTIONP, SCM_SLOPPY_FRACTIONP, SCM_FRACTION_NUMERATOR,

5646 * gc-card.c (scm_i_sweep_card): Include scm_tc16_fraction as a
5647 case in the switch, but do nothing for now.
5649 * eval.c (SCM_CEVAL, SCM_APPLY, call_dsubr_1): Convert fractions
5650 to doubles when calling 'dsubr' functions.
5652 * eq.c (scm_eqv_p, scm_equal_p): Handle fractions.
5654 2003-11-18 Rob Browning <rlb@defaultvalue.org>
5656 * gen-scmconfig.c (main): remove public definition of
5657 SCM_SIZEOF___INT64 and SCM_SIZEOF_UNSIGNED___INT64 and add
5658 direct typedef of long_long and ulong_long inside deprecated block
5661 * deprecated.h: move long_long and ulong_long definitions to
5662 gen-scmconfig.c so that we don't need to add SCM_SIZEOF___INT64
5663 and SCM_SIZEOF_UNSIGNED___INT64 to the public namespace.
5665 2003-11-17 Marius Vollmer <mvo@zagadka.de>
5667 * hash.c (scm_string_hash): New hashing algorithm that takes the
5668 complete string into account.
5670 * eval.c (scm_m_generalized_set_x): Macroexpand the target when it
5671 is a list. This allows (@ ...) to work with set!.
5672 (scm_m_generalized_set_x): Use ASSERT_SYNTAX_2 instead of
5675 * script.c (scm_compile_shell_switches): Use scm_c_read_string for
5676 the "-e" option instead of scm_str2symbol. This allows things
5677 like (@ ...) to be specified for the entry point.

5690 (s_test, s_bindings, s_duplicate_bindings, s_variable): Removed.
5692 (try_macro_lookup, literal_p): Use lookup_symbol instead of
5693 creating a temporary pair for scm_lookupcar.
5695 (scm_unmemocar, unmemocar): Renamed scm_unmemocar to unmemocar,
5696 created deprecated wrapper function scm_unmemocar.
5698 (SCM_VALIDATE_NON_EMPTY_COMBINATION, scm_sym_else,

5720 static helper functions for m_expand_body.
5722 (m_expand_body): Use ASSERT_SYNTAX to signal syntax errors. Only
5723 expand user defined macros. Fixed handling of the definition/
5724 expression boundary. Fixed handling of definitions grouped with
5725 'begin. Use canonicalize_define to expand definitions.
5727 2003-11-13 Marius Vollmer <mvo@zagadka.de>
5729 * read.c (scm_lreadr): detect EOF after backslash, and interpret
5730 \xNN hexadecimal sequences. From Paul Jarc, thanks!
5732 * snarf.h (SCM_SMOB, SCM_GLOBAL_SMOB, SCM_SMOB_MARK,

5881 (scm_m_quote, unmemocopy): As an optimization, vector constants
5882 are now inserted unquoted into the memoized code. During
5883 unmemoization the quotes are added again to provide syntactically
5886 2003-10-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
5888 * eval.c (scm_m_let, scm_m_letstar, scm_m_letrec,
5889 scm_m_expand_body, check_bindings): Extracted syntax checking of
5890 bindings to new static function check_bindings.

5905 (s_clauses, s_formals, s_duplicate_formals): Removed.
5907 (scm_m_lambda): Use ASSERT_SYNTAX to signal syntax errors. Be more

5964 Avoid unnecessary consing when creating the memoized code.
5966 2003-10-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
5968 * eval.c (s_extra_expression, s_misplaced_else_clause,
5969 s_bad_cond_clause, s_missing_recipient): New static identifiers.
5971 (s_extra_case_clause): Removed.
5973 (scm_m_case, scm_m_cond): If a clause appears after an else
5974 clause, report a misplaced else clause.
5976 (scm_m_cond): Use ASSERT_SYNTAX to signal syntax errors. Be more
5977 specific about the kind of error that was detected. Handle bound
5978 'else and '=>. Avoid unnecessary consing when creating the
5981 (scm_m_cond, unmemocopy, SCM_CEVAL): Use SCM_IM_ELSE to memoize
5982 the syntactic keyword 'else and SCM_IM_ARROW to memoize the
5983 syntactic keyword '=>.
5985 2003-10-11 Dirk Herrmann <D.Herrmann@tu-bs.de>

6004 (scm_m_case, unmemocopy, SCM_CEVAL): Use SCM_IM_ELSE to memoize
6005 the syntactic keyword 'else.
6007 2003-10-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
6009 * eval.c (s_bad_expression, syntax_error_key, syntax_error,

6020 2003-10-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
6022 * smob.h (scm_make_smob_type): Made the declaration match the

6027 * goops.c, objects.h, smob.c, smob.h: Make type names char
6028 const * instead of char *. Thanks to Paul Jarc!
6030 2003-10-02 Kevin Ryde <user42@zip.com.au>
6032 * strports.c (scm_call_with_output_string): scm_get_output_string
6033 rather than scm_strport_to_string, so as to guard against the port
6034 having been closed by the called procedure. Reported by Nic Ferrier.
6036 2003-09-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
6038 * numbers.h (SCM_INEXACTP): Removed uses of SCM_TYP16S.
6040 * tags.h, deprecated.h (SCM_TYP16S): Deprecated and moved from
6041 tags.h to deprecated.h.
6043 2003-09-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
6045 This set of patches introduces a new tc7 code scm_tc7_number for
6046 numbers. Bignums, reals and complex numbers are turned from smobs
6047 into subtypes of scm_tc7_number.
6049 * tags.h (scm_tc7_number): New.
6051 * eq.c (scm_equal_p), eval.c (SCM_CEVAL), evalext.c
6052 (scm_self_evaluating_p), gc-card.c (scm_i_sweep_card), gc-mark.c
6053 (scm_gc_mark_dependencies), goops.c (create_smob_classes), hash.c
6054 (scm_hasher), numbers.c, numbers.h (SCM_NUMP), objects.c
6055 (scm_class_of), print.c (scm_iprin1), smob.c
6056 (scm_smob_prehistory): Don't handle bignums, reals and complex
6057 numbers as subtypes of scm_tc7_smob any more.
6059 * numbers.h, tags.h (scm_tc16_big, scm_tc16_real,
6060 scm_tc16_complex): Moved definitions from tags.h to numbers.h.
6062 2003-09-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
6064 * numbers.c (scm_make_complex), gc-card.c (scm_i_sweep_card): Use
6065 sizeof (scm_t_complex) to determine the memory size of the
6066 malloc'd area for complex numbers.
6068 2003-09-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
6070 * numbers.c (scm_bigequal): Fixed.
6072 2003-09-16 Marius Vollmer <mvo@zagadka.de>
6074 * stime.c (scm_current_time): 'time' does not set errno so don't
6075 use SCM_SYSERROR for reporting errors.
6077 2003-09-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
6079 This set of patches eliminates the dependency between the
6080 implementation of evaluator specific memoization codes and special
6081 constants like #f, '() etc. ('flags'), which are not evaluator
6082 specific. The goal is to remove definitions of evaluator
6083 memoization codes completely from the public interface. This will
6084 make it possible to experiment more freely with optimizations of
6085 guile's internal representation of memoized code.
6087 * objects.c (scm_class_of): Eliminate dependency on SCM_ISYMNUM.
6089 * print.c (iflagnames): New array, holding the printed names of
6090 guile's special constants ('flags').
6092 (scm_isymnames): Now holds only the printed names of the
6095 (scm_iprin1): Separate the handling of memoization codes and
6096 guile's special constants.
6098 * tags.h (scm_tc9_flag, SCM_ITAG9, SCM_MAKE_ITAG9, SCM_ITAG9_DATA,
6101 (scm_tc8_char, scm_tc8_iloc, SCM_BOOL_F, SCM_BOOL_T,
6102 SCM_UNDEFINED, SCM_EOF_VAL, SCM_EOL, SCM_UNSPECIFIED, SCM_UNBOUND,
6103 SCM_ELISP_NIL, SCM_IM_DISPATCH, SCM_IM_SLOT_REF,
6104 SCM_IM_SLOT_SET_X, SCM_IM_DELAY, SCM_IM_FUTURE,
6105 SCM_IM_CALL_WITH_VALUES, SCM_IM_NIL_COND, SCM_IM_BIND): Changed
6108 (SCM_IFLAGP): SCM_IFLAGP now only tests for flags.
6110 (SCM_IFLAGP, SCM_MAKIFLAG, SCM_IFLAGNUM): Generalized to use the
6111 tc9 macros and scm_tc9_flag.
6113 2003-09-15 Marius Vollmer <mvo@zagadka.de>
6115 * posix.c (scm_setgroups): Check that the gid list is not too
6116 long. Thanks to Paul Jarc!
6118 2003-09-14 Dirk Herrmann <D.Herrmann@tu-bs.de>
6120 * tags.h: Reduced the number of short instructions from 14 to 13.
6121 The typecode of the former 14th short instruction is now used to
6122 represent long instructions. Changed some comments to reflect
6125 (SCM_MAKISYM): ISYMs get a new tc7 code, namely the one that was
6126 previously used by SCM_IM_DEFINE.
6128 (SCM_IM_DEFINE): Turned into a long instruction.
6130 * eval.c (unmemocopy, SCM_CEVAL): Treat SCM_IM_DEFINE as a long
6133 * eval.c (SCM_CEVAL): Since characters and iflags have now a tc7
6134 code that is separate from all instructions, one level of dispatch
6135 for long instructions can be eliminated.
6137 * print.c (scm_isymnames): Removed some commented code.
6139 2003-09-12 Marius Vollmer <mvo@zagadka.de>
6141 * __scm.h (SCM_FENCE): Use __memory_barrier with the Intel
6144 * hashtab.h (scm_tc16_hashtable): Added "extern" declaration.
6146 * modules.c (scm_module_reverse_lookup): Check that the obarray
6147 really is a hashtable and do nothing if not.
6149 * inline.h: Use "extern inline" only with GCC. Use "static
6152 2003-09-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
6154 * numbers.h (SCM_INEXACTP, SCM_REALP, SCM_COMPLEXP): Removed uses
6155 of SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP.
6157 * numbers.h, deprecated.h (SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP,
6158 SCM_SLOPPY_COMPLEXP): Deprecated and moved from numbers.h to
6161 2003-09-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
6163 * eq.c (scm_eqv_p, scm_equal_p): Removed uses of
6164 SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP.
6166 * eq.c (scm_eqv_p, scm_equal_p): Reordered comparisons from
6167 0.0==some_expression to some_expression==0.0. The latter is
6168 better readable. The former is preferred by some people, since it
6169 leads to a compiler error when confusing == with =. However, when
6170 using gcc, a warning will be issued if in an if-statement an
6171 assigment appears. Since many Guile developers are using gcc,
6172 such errors will not remain unnoticed anyway. We can therefore
6173 focus on better readability.
6175 2003-09-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
6177 * tags.h: Added description of Guile's type system. Removed some
6178 old and misleading comments.
6180 2003-09-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
6182 * unit.c (scm_cvref): Eliminate unnecessary uses of SCM_NIMP,
6183 SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP.
6185 2003-09-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
6187 * numbers.h (SCM_MAKINUM): Define in terms of scm_tc2_int.
6189 (SCM_INEXACTP, SCM_REALP, SCM_COMPLEXP): Define in terms of the
6190 respective SLOPPY macro.
6192 2003-09-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
6194 * eq.c (scm_equal_p): Use SCM_TYP7 to check if an object is of
6195 type string, not SCM_TYP7S.
6197 2003-09-03 Kevin Ryde <user42@zip.com.au>
6199 * numbers.c (scm_lognot): Correction to docstring, ones-complement not
6202 * stime.c (scm_strptime): Add comment about glibc strptime %s and
6203 current timezone requiring SCM_DEFER_INTS.

6207 * script.c (scm_compile_shell_switches): Make -s switch optional
6208 if file to be loaded does not begin with a `-'. (Thanks to Aaron
6209 VanDevender for the patch!)
6211 2003-08-30 Kevin Ryde <user42@zip.com.au>
6213 * numbers.c (scm_lognot): Rewrite using ~ and mpz_com, for directness
6214 and to have non-integer types rejected as per other logical funcs.
6216 2003-08-28 Kevin Ryde <user42@zip.com.au>
6218 * gc.h (scm_remember_upto_here_1): Revise comments on the asm form.
6220 2003-08-23 Kevin Ryde <user42@zip.com.au>
6222 * simpos.c (scm_system): Remove SCM_DEFER_INTS, system() should be
6223 thread safe, and could take a long time too.
6225 2003-08-22 Kevin Ryde <user42@zip.com.au>
6227 * numbers.c (scm_difference): Correction to bignum - negative inum.
6229 2003-08-14 Kevin Ryde <user42@zip.com.au>
6231 * gc.h (scm_remember_upto_here_1, scm_remember_upto_here_2)
6232 [__GNUC__]: Use volatile asm macros rather than a function call.
6233 * gc.c (scm_remember_upto_here_1, scm_remember_upto_here_2): Undefine
6234 macros while defining functions.
6236 * simpos.c (getenv): Use <stdlib.h> for prototype.
6237 (scm_system): In docstring, refer to status:exit-val rather than
6240 2003-08-09 Kevin Ryde <user42@zip.com.au>
6242 * srcprop.c (scm_source_properties): Return plist from hash if it's a
6243 list set by source-properties! rather than an SRCPROPS object,
6245 2003-07-29 Kevin Ryde <user42@zip.com.au>
6247 * properties.c (scm_primitive_property_ref): In docstring, note
6248 parameters to not-found-proc, use hyphens rather than underscores for
6249 that parameter name.
6250 (scm_primitive_property_set_x): In docstring, VAL is the value
6253 2003-07-27 Marius Vollmer <mvo@zagadka.de>
6255 * print.c (scm_print_symbol_name): handle more weird characters by
6256 escaping the symbol name properly. Thanks to Paul Jarc!
6258 * posix.h (scm_setgroups): New prototype.
6259 * posix.c (scm_setgroups): New. Thanks to Paul Jarc!
6260 (scm_getgroups): Handle groups ids that don't fit into a fixnum.
6261 Don't use SCM_WRITABLE_VELTS.
6263 * gc.h (SCM_GC_SET_CELL_BVEC): New.
6264 * gc-card.c (scm_i_init_card_freelist): Use it. Thanks to
6267 * __scm.h (SCM_C_INLINE_KEYWORD): New.
6268 * numbers.c: Use it in place of SCM_C_INLINE so that the code
6269 compiles when SCM_C_INLINE is undefined.
6271 2003-07-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
6273 * __scm.h: Reformulated the architecture and compiler properties
6274 in terms of properties of scm_t_bits and SCM variables rather than
6275 in terms of c standard types. This is since it is not known which
6276 of the standard types scm_t_bits and SCM variables will be defined
6279 2003-07-24 Kevin Ryde <user42@zip.com.au>
6281 * numbers.c (scm_angle): Use scm_flo0 for non-negative inum, bignum
6284 2003-07-18 Kevin Ryde <user42@zip.com.au>
6286 * numbers.c (scm_product): In complex * bignum, correction to
6287 REAL/IMAG fetch, x is the complex, not y.
6289 2003-07-13 Mikael Djurfeldt <djurfeldt@nada.kth.se>
6291 * numbers.c (scm_odd_p, scm_even_p): Bugfix: Treat result of
6292 scm_inf_p test as Scheme values.
6293 (scm_sum): Bugfix: Normalize bignum created from a negative bignum
6294 and a positive inum.
6295 Use GNU indentation style.

6299 * values.c (scm_values): Build lists of length 1 by using
6300 scm_list_1 instead of using scm_cons.

6304 * deprecation.c (scm_c_issue_deprecation_warning_fmt): Add va_end.
6305 * list.c (scm_list_n): Ditto.
6307 * gc-malloc.c (scm_gc_realloc): Define "ptr" at start of function.
6309 2003-07-08 Matthias Koeppe <mkoeppe@merkur.math.uni-magdeburg.de>
6311 * tags.h (scm_t_bits, scm_t_signed_bits, etc): Avoid solaris empty
6312 defines of INTPTR_MAX and UINTPTR_MAX, combine conditionals for
6313 scm_t_bits and scm_t_signed_bits to avoid any chance of one and not
6314 the other using intptr_t.
6316 2003-07-08 Kevin Ryde <user42@zip.com.au>
6318 * numbers.c (scm_make_polar): Use sincos, when available.
6319 (scm_magnitude): Use hypot.
6321 * ports.c (scm_char_ready_p, scm_peek_char): In docstrings, don't use
6322 @footnote since it doesn't go through to guile-procedures.txt.
6324 * threads.c (scm_call_with_new_thread): In docstring, use "( )"
6325 outside @var to quieten makeinfo, and use @code.
6327 2003-07-06 Han-Wen Nienhuys <hanwen@cs.uu.nl>
6329 * gc-malloc.c (decrease_mtrigger): new function
6330 (increase_mtrigger): new function, separate debug registering and
6331 mtrigger administration.
6332 (scm_gc_realloc): bugfix: do mtrigger administration before the
6333 actual realloc, for the realloc might invalidate a GC-d segment of
6334 memory. Thanks to Sam Hocevar for pointing this out.
6335 (scm_gc_realloc): use scm_malloc_reregister instead of
6336 unregistering and registering in sequence.
6338 2003-07-03 Han-Wen Nienhuys <hanwen@cs.uu.nl>
6340 * __scm.h (SCM_ASSERT): change "else" expansion to "do { } while (0)"

6366 * numbers.c (_GNU_SOURCE): #define, to get C99 things.
6367 (scm_asinh, scm_acosh, scm_atanh, scm_truncate, $asinh, $acosh,
6368 $atanh, truncate): Use C library asinh, acosh, atanh and trunc, when
6370 (scm_inexact_to_exact): Expand isfinite to its definition !xisinf.

6384 * threads.h: Redefined scm_getspecific() and scm_setspecific()
6385 to be functions instead of macros.
6387 * threads.c: Conditionalized inclusion of <sys/time.h> and
6389 (scm_getspecific, scm_setspecific): Made these two function
6390 real part of the API.
6392 * posix.c (s_scm_putenv): Added some code to make a
6393 (putenv "FOO="), i.e. setting an empty string, work also on
6394 Win32 systems. Thanks to Kevin Ryde for the proposal.
6396 2003-06-12 Kevin Ryde <user42@zip.com.au>
6398 * posix.c (scm_putenv): Free temporary ptr in mingw unset. Add

6404 getc/ungetc calls. Thanks to Dr. Peter Ivanyi!
6406 2003-06-07 Kevin Ryde <user42@zip.com.au>

6419 scm_tcs_closures): Hard coded values replaced by symbolic ones.
6421 2003-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
6423 * eval.c: Partially undid my patch from 2003-05-31. This patch
6424 caused the segfault referenced in the previous changelog entry.
6426 2003-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
6428 * tags.h: Fixed comment about the immediate type code layout.
6430 * eval.c: Fixed handling of non-special instructions. Without
6431 this patch, guile will segfault on (#\0) and similar instructions.
6433 2003-06-05 Kevin Ryde <user42@zip.com.au>
6435 * numbers.c (scm_max, scm_min): For inum, bignum and real, if other
6436 operand is NaN, then return NaN. Also avoid passing NaN to mpz_cmp_d.
6438 * read.c (scm_input_error): Pass arg list parameter to scm_error_scm,
6439 rather than SCM_EOL. Needed by "Unknown # object" case in scm_lreadr.
6441 2003-06-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
6443 * __scm.h, gc-card.c (SCM_DEBUG_DEBUGGER_SUPPORT,
6444 SCM_DEBUG_DEBUGGING_SUPPORT): Renamed macro
6445 SCM_DEBUG_DEBUGGER_SUPPORT to SCM_DEBUG_DEBUGGING_SUPPORT and

6452 eval.c, made them available under SCM_DEBUG_DEBUGGING_SUPPORT == 1
6453 only and renamed them to scm_dbg_make_iloc, scm_dbg_iloc_p,
6456 * deprecated.h, eval.c, eval.h (SCM_ILOC00, SCM_IDINC,
6457 SCM_IDSTMSK): Deprecated. The macro definitions are moved from
6458 eval.h into eval.c and a copy is placed into deprecated.h.
6460 * eval.c, eval.h (SCM_MAKE_ILOC): Removed from eval.h and placed
6461 into eval.c. This definition was not part of the API in any
6462 officially released version of guile and thus does not need to go
6463 through a phase of deprecation.
6465 2003-06-02 Dirk Herrmann <D.Herrmann@tu-bs.de>
6467 * deprecated.c, deprecated.h, eval.c, eval.h (scm_s_expression,
6468 scm_s_test, scm_s_body, scm_s_bindings, scm_s_variable,
6469 scm_s_clauses, scm_s_formals): Deprecated. In eval.c the
6470 definitions are make static and renamed from scm_s_xxx to s_xxx.
6471 In deprecated.c the original definitions are copied.
6473 * deprecated.h, eval.c, eval (SCM_EVALIM2, SCM_EVALIM, SCM_XEVAL,
6474 SCM_XEVALCAR): Deprecated. The macro definitions are moved from
6475 eval.h into eval.c and a copy (slightly modified to work in user
6476 code) is placed into deprecated.h.
6478 * eval.c: Use the local static s_xxx definitions instead of the
6479 scm_s_xxx definitions throughout.
6481 2003-06-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
6483 This set of patches separates the representation of the cxr family
6484 of functions (car, cdr etc.) from the dsubr family of functions
6485 (i. e. functions that take a double precision floating point
6486 argument). Further, the algorithm for handling the cxr function

6502 of a scm_tc7_cxr function to implement the cxr family of functions
6505 2003-05-31 Dirk Herrmann <D.Herrmann@tu-bs.de>
6507 * eval.c (SCM_CEVAL, SCM_APPLY, scm_trampoline_0,

6509 end of an if-else-if-sequence of checks.
6511 2003-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
6513 * eval.c (SCM_CEVAL): Improved readability of call-with-values
6514 execution. Generalize apply_closure to apply_proc and use that
6515 for call-with-values.
6517 2003-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
6519 * eval.c (SCM_CEVAL): Avoid one level of indirection when applying

6543 * posix.c (s_scm_putenv): Disable use of unsetenv() for the
6546 * modules.c (s_scm_module_import_interface): Renamed local
6547 variable interface to _interface. Seems like 'interface'
6548 is a special compiler directive for the mingw32 compiler.
6550 * mkstemp.c: Provide prototype to avoid compiler warning.
6552 * load.c (s_scm_search_path): Fixed absolute and relative
6553 path detections for native Windows platforms.
6555 * gc.h, threads.h: Export some more symbols using SCM_API (necessary

6628 a compilation error if error-on-warning is enabled).
6630 2003-05-17 Marius Vollmer <mvo@zagadka.de>
6632 * c-tokenize.lex: Gobble up complete lines after a '#'. This
6633 removes preprocessor directives from the snarfage that might
6634 otherwise confuse us. These directives appear when compiling with

6688 * eval.c, eval.h, read.c, read.h (scm_sym_dot): Moved from eval to

6704 The purpose of this patch is to make guile's internal memoizers
6705 distinguishable from memoizing macros created on the scheme level
6706 or from user provided primitive memoizing macros. The reason is,
6707 that the internal memoizers are the only ones that are allowed to
6708 transform their scheme input into memoizer byte code, while all
6709 other memoizing macros may only transform scheme code into new
6712 To achieve this, a new macro type 'builtin-macro!' is introduced.
6713 Currently, 'builtin-macro!'s are handled as memoizing macros, but
6714 this will change when the memoizer and executor are separated.
6716 * macros.[ch] (scm_i_makbimacro): New.
6718 * macros.h (SCM_BUILTIN_MACRO_P): New.
6720 * macros.c (macro_print, scm_macro_type): Support builtin-macro!s.
6722 * eval.c, goops.c: All of guile's primitive memoizing macros are
6723 primitive builtin-macros now.
6725 * eval.c (scm_macroexp, SCM_CEVAL): Make sure the primitive
6726 builtin-macros are handled equally to memoizing macros.
6728 2003-05-04 Marius Vollmer <mvo@zagadka.de>
6730 * throw.c (scm_ithrow): Remove "asm volatile" hack. It used to
6731 work around a bug in GCC 2.95.2 but is now a bug in itself.

6758 macro was introduced in anticipation of GOOPS method compilation
6761 * goops.c: Removed binding of @dispatch.
6763 2003-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
6765 * eval.c, goops.c (@dispatch, @slot-ref, @slot-set!): Move the
6766 instructions that bind the macros on the scheme level back to
6767 goops.c in order to make sure again that the bindings go into the
6768 (oop goops) module and are not visible from the outside.
6770 2003-04-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
6772 * eval.c: Non functional change: Separated R5RS and non-R5RS

6782 * eval.c (scm_i_call_closure_0, call_closure_1, call_closure_2):
6783 Partially reverted patch from 2003-04-23 in oder to find a better
6784 compromise between readability and debuggability.
6786 2003-04-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
6788 * eval.c, eval.h, goops.c, goops.h (scm_m_atslot_ref,
6789 scm_m_atslot_set_x, scm_m_atdispatch): Move the declarations and
6790 definitions of the special goops memoizers from goops.[ch] to

6813 2003-04-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
6815 This set of patches contains no functional changes, only debatable
6816 minor stylistic ones. Still, in order to prepare a patch between
6817 my local copy and the CVS version, I decided to submit the changes
6818 below. Then, the patch will hopefully only contain relevant
6821 * eval.c (iqq): Added const specifier.
6823 * eval.c (scm_trampoline_0, scm_trampoline_1, scm_trampoline_2):
6824 Use NULL instead of 0 to indicate that a pointer is returned.
6825 Removed some misleading 'fall through' comments.
6827 * eval.c (scm_i_call_closure_0, call_closure_1, call_closure_2):
6828 Split up long expressions into smaller ones to be more debugging
6831 2003-04-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
6833 * eval.h (SCM_ENTER_FRAME_HDLR, SCM_APPLY_FRAME_HDLR,
6834 SCM_EXIT_FRAME_HDLR): Use SCM_PACK to convert data to a SCM value
6835 rather than casting to SCM.
6837 2003-04-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
6839 * sort.c, pairs.h: Removed unnecessary includes.
6841 2003-04-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
6843 * sort.c: Replaced hand-made trampline code by the new official
6844 mechanism from eval.c. This fixes a segfault in the new test file
6847 (quicksort, compare_function, scm_restricted_vector_sort_x,
6848 scm_sorted_p, scm_merge, scm_merge_list_x, scm_merge_x,

6855 cmp_fun_t): Removed.
6857 (compare_function): Added.
6859 * sort.c (quicksort, SWAP, stack_node): Replaced pointer
6860 arithmetics with index arithmetics. Changed quicksort to work on
6861 an array of SCM values instead of an array of characters. Avoid
6862 bytewise copying of SCM elements. Avoid allocating memory on the
6863 stack with alloca. Fixed some comments.
6865 2003-04-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
6867 * eval.c (EXTEND_ENV): Eliminated.
6869 (unmemocopy, SCM_CEVAL, SCM_APPLY): Use SCM_EXTEND_ENV instead of

6874 * __scm.h (SCM_DEBUG_DEBUGGER_SUPPORT): New compile-time option.
6876 * gc.card.c (scm_gc_marked_p): Fixed compiler warning when
6877 compiling with SCM_DEBUG==1 by moving definition behind prototype.
6879 * gc.card.c (scm_dbg_t_list_cell, scm_dbg_t_double_cell,
6880 scm_dbg_gc_marked_p, scm_dbg_gc_get_card, scm_dbg_gc_get_bvec,
6881 scm_t_list_cell_struct, scm_t_list_cell, scm_t_double_cell,
6882 scm_gc_marked_p, scm_gc_get_card, scm_gc_get_bvec): Fixed
6883 functions such that they check if the object is a non-immediate.
6884 Further, renamed identifiers to use the scm_dbg_ prefix and made
6885 their inclusion into the lib dependent of the
6886 SCM_DEBUG_DEBUGGER_SUPPORT compile time option.
6888 2003-04-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
6890 * __scm.h: Fixed comment about the SCM_DEBUG_TYPING_STRICTNESS
6893 2003-04-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
6895 * list.c (scm_ilength, scm_last_pair), unif.c (l2ra): Prefer
6896 !SCM_CONSP over SCM_NCONSP. Now, guile itself does not include
6897 any calls to SCM_NCONSP any more.
6899 * unif.c (l2ra): Eliminate redundant check.
6901 2003-04-21 Dirk Herrmann <D.Herrmann@tu-bs.de>

6912 other expressions into an expression of their own.
6914 2003-04-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
6916 * goops.c (TEST_CHANGE_CLASS, scm_sys_initialize_object): Don't
6917 compare SCM values with !=.
6919 2003-04-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
6921 * eval.c, eval.h, evalext.c, evalext.h (scm_sym_setter,
6922 scm_m_generalized_set_x, scm_init_evalext): Move the declaration
6923 and definition of the memoizer for the generalized set! macro from
6924 evalext.[ch] to eval.[ch]. Use the SCM_SYNTAX snarfer macro to
6925 define the macro object.
6927 * eval.c, eval.h (s_set_x, scm_s_set_x, scm_m_set_x,
6928 scm_m_generalized_set_x): Since now scm_s_set_x is only used in
6929 eval.c, it is made static and renamed to s_set_x.
6931 * evalext.c (scm_defined_p, scm_m_undefine): Prefer !SCM_<foo>
6934 2003-04-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
6936 * eval.c, root.h (scm_undefineds, SCM_NUM_PROTECTS, undefineds,
6937 scm_init_eval): Made scm_undefineds static in eval.c, renamed it
6938 to undefineds and registered the object as a permanent object.
6940 * eval.c, eval.h (scm_f_apply, scm_init_eval): Made scm_f_apply
6941 static in eval.c, renamed it to f_apply and registered the object
6942 as a permanent object.
6944 2003-04-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
6946 * eval.c (SCM_BIT7, SCM_BIT8, unmemocopy, SCM_CEVAL): Renamed
6947 file-local macro SCM_BIT8 to SCM_BIT7, which is more appropriate.
6949 2003-04-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
6951 * numbers.c (scm_logtest): Fixed argument bug in the call to
6952 mpz_and, which showed up when compiling with SCM_DEBUG defined.

7009 2003-04-13 Rob Browning <rlb@defaultvalue.org>
7011 * __scm.h (SCM_FLUSH_REGISTER_WINDOWS): don't just rely on "sparc"
7013 #if defined (sparc) || defined (__sparc__) || defined (__sparc)
7014 as gc_os_dep.c suggests is appropriate.
7016 * goops.c (prep_hashsets): make static to match prototype.
7017 (scm_sym_args): SCM_SYMBOL -> SCM_GLOBAL_SYMBOL. Thanks to Albert
7020 * c-tokenize.lex: remove trailing comma from enum. Thanks to

7057 * posix.h: change occurences of "id" to something else so we don't
7058 cause trouble when included via objective-c (can't hurt, might
7059 help). Still have usage in debug.h, though.
7061 2003-04-06 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7063 * random.c (scm_c_random_bignum): Don't generate a random number

7065 generate numbers in the range 0 <= r < m.
7066 (scm_c_default_rstate): Use SCM_VARIABLE_REF to access
7067 scm_var_random_state.
7069 * num2integral.i.c (INTEGRAL2BIG): Put negation of n inside then

7428 USE_NULL_THREADS to SCM_USE_NULL_THREADS. Rename usage of
7429 USE_COPT_THREADS to SCM_USE_COPT_THREADS.
7431 * inline.c: rearrange handling -- now we just #define
7432 SCM_INLINE_C_INCLUDING_INLINE_H to 1 and #include
7433 "libguile/inline.h". scmconfig.h will define SCM_C_INLINE as
7434 appropriate, and we use that in inline.h along with the above
7435 define to determine how to respond.

7492 HAVE_ARRAYS to SCM_HAVE_ARRAYS. Replace usage of HAVE_LONG_LONGS
7493 with "SCM_SIZEOF_LONG_LONG != 0".
7495 * deprecation.c: #include <config.h> if HAVE_CONFIG_H.
7497 * coop.c: replace usage of struct timespect with scm_t_timespec.
7498 #include <config.h> if HAVE_CONFIG_H.

7510 HAVE_WINSOCK2_H to SCM_HAVE_WINSOCK2_H. Replace usage of struct
7511 timespect with scm_t_timespec.
7513 * convert.i.c: rename usage of HAVE_ARRAYS to SCM_HAVE_ARRAYS.
7515 * convert.h: rename usage of HAVE_ARRAYS to SCM_HAVE_ARRAYS.
7517 * convert.c: #include <config.h> if HAVE_CONFIG_H. Rename usage
7518 of HAVE_ARRAYS to SCM_HAVE_ARRAYS.
7520 * continuations.c: move libguile/_scm.h include to the top so we
7521 pick up any critical defines like _GNU_SOURCE early.
7523 * backtrace.c: #include <config.h> if HAVE_CONFIG_H.

7535 appropriate. STDC_HEADERS based inclusion of stdlib.h,
7536 sys/types.h, stddef.h, and sys/stdtypes.h removed in favor of

7540 (HAVE_UINTPTR_T): definition removed (see NEWS).
7541 (SIZEOF_PTRDIFF_T): definition removed (see NEWS).
7542 (HAVE_LONG_LONGS): definition removed (see NEWS).
7543 (HAVE_LONG_LONG): definition removed (see NEWS).
7544 (HAVE_PTRDIFF_T): definition removed (see NEWS).
7546 * Makefile.am: scmconfig.h is now generated by building and
7547 running gen-scmconfig.h and capturing its output. gen-scmconfig
7548 uses config.h and the configure.in generated gen-scmconfig.h to
7549 decide what to output. See gen-scmconfig.c for details.
7550 (noinst_PROGRAMS): add gen-scmconfig.
7551 (gen_scmconfig_SOURCES): new variable.
7552 (gen-scmconfig.$(OBJEXT)): new target - be careful to handle
7553 cross-compiling right.
7554 (scmconfig.h): build scmconfig.h from gen-scmconfig's output.
7555 (BUILT_SOURCES): add scmconfig.h.
7557 2003-03-19 Marius Vollmer <mvo@zagadka.de>
7559 * gc_os_dep.c: Added defines for sparc-unknown-netbsdelf1.5 from
7560 Adrian Bunk. Thanks!
7562 2003-03-19 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7564 * goops.c (make_class_from_template): New fourth arg:
7566 (scm_class_extended_generic_with_setter, scm_class_self): Fixed
7569 * smob.c (scm_set_smob_apply): Call scm_i_inherit_applicable.
7571 * goops.c, objects.c, objects.h (scm_make_extended_class): New

7575 * goops.c, goops.h (scm_class_applicable,
7576 scm_class_extended_accessor): New classes.
7578 2003-03-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
7580 * procs.c (scm_procedure_documentation): Removed redundant
7581 SCM_NIMP test and replaced other calls to SCM_IMP by more explicit

7597 generic if not enabled.
7598 (scm_sys_goops_loaded): Setup unextended primitive generics.
7600 * goops.c, goops.h (scm_c_extend_primitive_generic): New function.
7602 * snarf.h (SCM_PRIMITIVE_GENERIC, SCM_PRIMITIVE_GENERIC_1): New
7605 * numbers.c (scm_abs): Use SCM_PRIMITIVE_GENERIC. (This is only a
7606 testing example. All uses of SCM_GPROC should be converted.)
7608 * procprop.c (scm_stand_in_scm_proc): Use scm_assq instead of
7611 * eq.c (scm_equal_p): Turned into a primitive generic.
7613 2003-02-27 Rob Browning <rlb@defaultvalue.org>
7615 * Makefile.am (scmconfig.h): new target -- generate file from
7617 (modinclude_HEADERS): remove version.h.
7618 (nodist_modinclude_HEADERS): add version.h.
7620 2003-02-24 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7622 This fixes a serious GC bug, introduced during the latest
7623 reorganization of the GC, which disabled freeing of structs and
7626 * struct.c (scm_struct_prehistory): Init scm_i_structs_to_free to
7628 (scm_struct_prehistory): Move scm_free_structs to
7629 scm_before_mark_c_hook.
7631 * gc-card.c (sweep_card): Check that we haven't swept structs on
7632 this card before. That can happen if scm_i_sweep_all_segments has
7633 been called from some other place than scm_igc.
7635 2003-02-19 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7637 * environments.c (DEFAULT_OBARRAY_SIZE): Changed from 137 to 31
7638 (since hash tables now adapt their size).
7640 * modules.c (scm_modules_prehistory): Changed from 2001 to 1533
7641 (current number of prehistory bindings; hashtable code will select
7642 a prime which is greater than this value).
7644 * symbols.c (scm_symbols_prehistory): Changed from 1009 to 2139
7645 (current number of initial symbols).

7648 scm_properties_whash.
7650 * objprop.c (scm_init_objprop): Don't specify size of
7653 * keywords.c (scm_init_keywords): Don't specify a hash table size.
7655 * hooks.c (scm_c_hook_add): Fixed bug in append mode.
7657 The following changes introduce the use of resizable hash tables
7658 throughout Guile. It also renames the old *-hash-table* functions
7659 to *-alist-vector* and places them, together with the rest of the
7660 weak vector support, in the module (ice-9 weak-vector). We should
7661 probably introduce a new, better, API for weak references, for
7662 example "weak pairs" a la MIT-Scheme. (In Chez scheme, they even
7663 look like and are used like ordinary pairs.)
7665 * environments.c (obarray_enter, obarray_retrieve, obarray_remove,
7666 leaf_environment_fold, obarray_remove_all): Use hashtable
7669 * gc.c (scm_init_storage): Moved hook initialization to
7670 scm_storage_prehistory.

7677 SCM_WVECT_WEAK_VALUE_P.
7679 * hashtab.c, hashtab.h (scm_hash_for_each, scm_hash_map): New
7681 (scm_vector_to_hash_table, scm_c_make_resizing_hash_table):

7684 scm_make_doubly_weak_hash_table): Moved here from weaks.c.
7686 * init.c (scm_init_guile_1): Removed call to scm_init_weaks; Added
7687 calls to scm_storage_prehistory and scm_hashtab_prehistory.
7689 * modules.c (module-reverse-lookup): Use hashtable accessors.
7691 * symbols.c, symbols.h (scm_i_hash_symbol): New function.
7693 * weaks.c, weaks.h (scm_make_weak_key_alist_vector,
7694 scm_make_weak_value_alist_vector,
7695 scm_make_doubly_weak_alist_vector): New functions.
7697 * weaks.c (scm_init_weaks_builtins): New function.
7699 * weaks.h (SCM_WVECTF_WEAK_KEY, SCM_WVECTF_WEAK_VALUE,
7700 SCM_WVECTF_NOSCAN, SCM_WVECT_WEAK_KEY_P, SCM_WVECT_WEAK_VALUE_P,
7701 SCM_WVECT_NOSCAN_P): New macros.
7703 * weaks.c (scm_scan_weak_vectors): Use SCM_WVECT_WEAK_KEY_P
7704 and SCM_WVECT_WEAK_VALUE_P.
7706 * weaks.c, weaks.h (scm_i_allocate_weak_vector): Renamed from
7707 allocate_weak_vector and exported.
7709 2003-02-13 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7711 * hashtab.c: Undid thread safety. (We decided that it's better to
7712 let the user explicitly protect the tables (or not) according what
7713 is suitable for the application.)
7715 2003-02-12 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7717 * hashtab.c (scm_hash_fn_remove_x, scm_internal_hash_fold): Made
7718 thread safe and handle resizing tables.
7719 (scm_ihashx, scm_sloppy_assx, scm_delx_x): Removed
7720 SCM_DEFER/ALLOW_INTS.
7722 2003-02-11 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7724 * hashtab.c (scm_vector_to_hash_table,
7725 scm_c_make_resizing_hash_table, scm_make_hash_table): New
7727 (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x): Made thread
7728 safe and handle resizing tables.
7730 * weaks.c (scm_make_weak_key_hash_table,
7731 scm_make_weak_value_hash_table, scm_make_doubly_weak_hash_table):
7732 Size argument made optional. Return resizable table if not
7735 2003-02-10 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7737 * eval.c (scm_trampoline_0, scm_trampoline_1, scm_trampoline_2):
7738 Fixed formals tests for closures. (Thanks to Kevin Ryde.)
7740 2003-02-05 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7742 * debug.c (scm_procedure_source): Handle all objects for which
7743 procedure? is #t. (Thanks to Bill Schottstaedt.)
7745 2003-01-23 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7747 * futures.c (mark_futures): Don't need to mark data of recycled
7749 (scan_futures, cleanup_undead): Be smarter about marking
7750 futures---avoid unnecessary passes through future lists.
7752 * futures.h, futures.c: New files; Introduced recycling of
7753 futures. For fine-grained threading this lifts performance to
7754 another level. We can now use parallelization in inner loops of

7765 create_thread and made global.
7767 * futures.c (scm_make_future): New procedure.
7769 * eval.c: #include "libguile/futures.h".
7771 * init.c: #include "futures.h"
7772 (scm_init_guile_1): Call scm_init_futures.
7774 * stime.c (SCM_TIME_UNITS_PER_SECOND): Renamed from CLKTCK.
7776 * stime.h (SCM_TIME_UNITS_PER_SECOND): Definition moved here.

7781 * eval.c (scm_trampoline_1): Fixed arguments test for closures.
7783 2003-01-22 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7785 * threads.c (create_thread): Don't unwind dynwind chain of parent
7786 thread before creation. Just start the new thread with an empty

7796 waiting also for simple condition variables.
7798 * goops.c (TEST_CHANGE_CLASS): Use scm_change_object_class instead

7812 (scm_compute_applicable_methods): Use scm_generic_function_methods.
7814 * goops.c (scm_generic_function_methods): Support extended
7817 2002-12-29 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7819 * eval.c (unmemocopy): Bugfix: scm_sym_delay --> scm_sym_future.
7820 Thanks to Neil for pointing this out!
7822 2002-12-29 Neil Jerram <neil@ossau.uklinux.net>
7824 * lang.h: Remove declarations matching definitions removed from
7825 lang.c (just below).
7827 2002-12-28 Neil Jerram <neil@ossau.uklinux.net>
7829 * lang.c (scm_nil_cons, scm_nil_car, scm_nil_cdr, scm_null,
7830 scm_m_while, scm_nil_eq): Remove definitions that were superfluous
7831 and already commented out.
7833 * read.h (scm_lreadparen), read.c (scm_lreadr, scm_read_token,
7834 scm_lreadparen): Support reading vectors with Elisp syntax if
7835 SCM_ELISP_READ_EXTENSIONS is defined. (SCM_ELISP_READ_EXTENSIONS
7836 is not currently defined, and there isn't even a configure switch
7839 2002-12-26 Marius Vollmer <mvo@zagadka.ping.de>
7841 * Makefile.am (c-tokenize.o): Refer to source via $< so that vpath
7843 (EXTRA_DIST): Added version.h.in.
7845 2002-12-21 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7847 This change makes it possible for one thread to do lazy sweeping
7848 while other threads are running. Now only the mark phase need to
7849 have all threads asleep. We should look further into this issue.
7850 Presently, I've put the locking of scm_i_sweep_mutex at
7851 "conservative" places due to my current lack of knowledge about
7852 the garbage collector. Please feel free to restrict these regions
7853 further to allow for maximal parallelism!
7855 * gc.c, gc.h (scm_i_sweep_mutex): New mutex.
7857 * gc.c (scm_gc_for_newcell), gc-malloc.c (scm_realloc,
7858 scm_gc_register_collectable_memory): Substitute locking of
7859 scm_i_sweep_mutex for calls to scm_i_thread_put_to_sleep.
7860 (scm_igc): Lock sweep mutex here instead of in callers; Calls to
7861 scm_i_thread_put_to_sleep/scm_i_thread_wake_up used to demarkate
7862 the single-thread section (which now only contains the mark
7864 (scm_gc): Don't lock sweeo mutex here since scm_igc locks it;
7865 Removed SCM_DEFER/ALLOW_INTS. Simply call scm_igc directly.
7867 * threads.c (gc_section_mutex): Removed.
7869 2002-12-19 Mikael Djurfeldt <mdj@kvast.blakulla.net>
7871 * threads.c (create_thread): Clear parent field in root state in
7872 order not to unnecessarily remember dead threads.
7874 * eval.c (call_subr2o_1, call_lsubr2_2): New functions.
7875 (scm_trampoline_1, scm_trampoline_2): Use them.
7877 2002-12-18 Mikael Djurfeldt <mdj@kvast.blakulla.net>
7879 Partial introduction of real plugin interface.
7881 * Makefile.am (modinclude_HEADERS): Added threads-plugin.h.
7882 (EXTRA_DIST): Added threads-plugin.c.
7884 * threads-plugin.h, threads-plugin.c: New files.
7886 * threads.h: #include "libguile/threads-plugin.h".
7888 * threads.c: #include "libguile/threads-plugin.c".
7890 * pthread-threads.c: Temporarily remove debugging functions.
7892 * threads.c, threads.h (scm_yield): Added back.
7894 2002-12-18 Mikael Djurfeldt <mdj@kvast.blakulla.net>
7896 * threads.c (really_launch): Detach before unlocking
7897 thread_admin_mutex in order not to risk being joined.
7898 (scm_i_thread_put_to_sleep, scm_i_thread_wake_up): Keep
7899 thread_admin_mutex locked during GC.
7901 * pthread-threads.c, pthread-threads.h: Improvements to debugging
7904 2002-12-16 Mikael Djurfeldt <mdj@kvast.blakulla.net>
7906 * pthread-threads.c, pthread-threads.h (SCM_DEBUG_THREADS): Added
7907 support for debugging mutex operations.
7909 * threads.c (scm_thread): Removed filed joining_threads.
7910 (thread_print): Print thread number as well as address of thread
7912 (scm_join_thread): Bugfix.
7913 (scm_lock_mutex, scm_try_mutex, scm_unlock_mutex,
7914 scm_timed_wait_condition_variable, scm_signal_condition_variable,
7915 scm_broadcast_condition_variable): Use the low-level API.
7916 (scm_all_threads): Return copy of thread list (to prevent
7917 unintended destruction).
7918 (scm_threads_prehistory): Initialize heap_mutex of fake thread.
7920 * pthread-threads.c, pthread-threads.h, threads.c: Fixes to
7921 pthread "native" recursive mutex support.
7923 2002-12-15 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7925 * __scm.h (SCM_DEFER_INTS, SCM_ALLOW_INTS): New definitions.
7926 Simply lock a thread C API recursive mutex.
7927 (SCM_NONREC_CRITICAL_SECTION_START,
7928 SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START,
7929 SCM_REC_CRITICAL_SECTION_END): Removed.
7931 * eval.c: Replaced SOURCE_SECTION_START / SOURCE_SECTION_END with
7932 direct calls to scm_rec_mutex_lock / unlock around the three calls
7933 to scm_m_expand_body.
7935 * eval.c, eval.h (promise_free): New function.
7936 (scm_force): Rewritten; Now thread-safe; Removed
7937 SCM_DEFER/ALLOW_INTS.
7939 * pthread-threads.h: Added partially implemented plugin interface
7940 for recursive mutexes. These are, for now, only intended to be
7941 used internally within the Guile implementation.
7943 * pthread-threads.c: New file.
7945 * threads.c: Conditionally #include "pthread-threads.c".
7947 * eval.c, eval.h (scm_makprom, scm_force): Rewritten to be
7950 * snarf.h (SCM_MUTEX, SCM_GLOBAL_MUTEX, SCM_REC_MUTEX,
7951 SCM_GLOBAL_REC_MUTEX): New macros.
7953 * eval.c, threads.c, threads.h, snarf.h: Rewrote critical section

7956 * tags.h (SCM_IM_FUTURE): New tag.
7958 * eval.c (scm_m_future): New primitive macro.
7959 (SCM_CEVAL): Support futures.
7960 (unmemocopy): Support unmemoization of futures.
7962 * print.c (scm_isymnames): Name of future isym.
7964 * version.c: Unmade some changes to my private copy that got
7965 committed by mistake.
7967 2002-12-11 Mikael Djurfeldt <mdj@kvast.blakulla.net>
7969 * gc-malloc.c, gc.h, init.c: Reverted gc-malloc change of
7972 * gc.c (scm_igc): Don't call scm_i_thread_invalidate_freelists.
7974 * gc.c (scm_gc_sweep): Call it here instead, which is a more
7977 * threads.c (create_thread): Remember root object until the handle
7978 of the new thread is on all_threads list.
7980 * root.c (scm_make_root): Moved copying of fluids until after
7981 creation of root handle so that the fluids are GC protected. Also
7982 removed the critical section.
7984 2002-12-10 Mikael Djurfeldt <mdj@kvast.blakulla.net>
7986 * gc-malloc.c, gc.h (scm_gc_malloc_prehistory): New function.
7988 * gc-malloc.c (malloc_mutex): New mutex.
7989 (scm_gc_malloc_prehistory): Initialize it.
7990 (scm_realloc): Serialize call to realloc
7991 (scm_calloc): Same for calloc.
7992 Thanks to Wolfgang Jaehrling!
7993 (Now we have to make sure all calls to malloc/realloc are made
7994 through scm_malloc.)
7996 * init.c (scm_init_guile_1): Call scm_gc_malloc_prehistory.
7998 * threads.c (really_launch): Release heap (to prevent deadlock).
7999 (create_thread): Release heap before locking thread admin mutex.
8001 2002-12-10 Mikael Djurfeldt <mdj@kvast.blakulla.net>
8003 * threads.c (scm_i_thread_invalidate_freelists): New
8006 * gc.c (scm_igc): Call scm_i_thread_invalidate_freelists.
8008 * modules.c (scm_export): Inserted a return statement.
8010 2002-12-10 Han-Wen Nienhuys <hanwen@cs.uu.nl>
8012 * modules.c (scm_export): new function
8014 * gc-card.c: add a note about malloc()/free() overhead.
8016 2002-12-10 Mikael Djurfeldt <mdj@kvast.blakulla.net>
8018 * Makefile.am (c-tokenize.$(OBJEXT)): Don't look for c-tokenize.c
8021 2002-12-10 Mikael Djurfeldt <djurfeldt@nada.kth.se>
8023 These changes remove scm_ints_disabled (which hasn't has any
8024 effect in Guile for quite some time).
8026 * async.c, error.h (scm_ints_disabled): Removed.
8028 * gc.c (scm_gc_for_newcell), init.c (scm_init_guile_1),
8029 root.c (scm_internal_cwdr), gdbint.c (SCM_BEGIN_FOREIGN_BLOCK,
8030 SCM_END_FOREIGN_BLOCK): Don't touch scm_ints_disabled.
8031 (old_ints): Removed.
8033 * __scm.h (SCM_DEFER_INTS, SCM_ALLOW_INTS): Define as a recursive
8035 (SCM_REDEFER_INTS, SCM_ALLOW_INTS): Define as SCM_DEFER_INTS and
8038 2002-12-09 Mikael Djurfeldt <djurfeldt@nada.kth.se>
8040 * threads.c (scm_mutex_lock, scm_cond_wait, scm_cond_timedwait):
8041 Removed accidental #if 0 around these functions.
8043 These changes are the start of support for preemptive
8044 multithreading. Marius and I have agreed that I commit this code
8045 into the repository although it isn't thoroughly tested and surely
8046 introduces many bugs. The bugs should only be exposed when using
8047 threads, though. Signalling and error handling for threads is
8048 very likely broken. Work on making the implementation cleaner and
8049 more efficient is needed.
8051 * __scm.h (SCM_ALLOW_INTS_ONLY): Removed.
8052 (SCM_NONREC_CRITICAL_SECTION_START,
8053 SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START,
8054 SCM_REC_CRITICAL_SECTION_END): New macros.
8055 (SCM_CRITICAL_SECTION_START/END): Defined here.
8057 * eval.c: Insert SOURCE_SECTION_START / SOURCE_SECTION_END around
8058 the three calls to scm_m_expand_body.
8060 * gc.h: #include "libguile/pthread-threads.h";
8061 (SCM_FREELIST_CREATE, SCM_FREELIST_LOC): New macros.
8063 * gc.c (scm_i_freelist, scm_i_freelist2): Defined to be of type
8066 * gc.c, gc-freelist.c, inline.h: Use SCM_FREELIST_LOC for freelist
8069 * gc-freelist.c (scm_gc_init_freelist): Create freelist keys.
8071 * gc-freelist.c, threads.c (really_launch): Use
8072 SCM_FREELIST_CREATE.
8074 * gc-malloc.c (scm_realloc, scm_gc_register_collectable_memory):
8076 * gc.c (scm_i_expensive_validation_check, scm_gc,
8077 scm_gc_for_newcell): Put threads to sleep before doing GC-related
8078 heap administration so that those pieces of code are executed
8079 single-threaded. We might consider rewriting these code sections
8080 in terms of a "call_gc_code_singly_threaded" construct instead of
8081 calling the pair of scm_i_thread_put_to_sleep () and
8082 scm_i_thread_wake_up (). Also, we would want to have as many of
8083 these sections eleminated.
8085 * init.c (scm_init_guile_1): Call scm_threads_prehistory.
8087 * inline.h: #include "libguile/threads.h"
8089 * pthread-threads.h: Macros now conform more closely to the
8090 pthreads interface. Some of them now take a second argument.
8092 * threads.c, threads.h: Many changes.
8094 2002-12-09 Mikael Djurfeldt <djurfeldt@nada.kth.se>
8096 * Makefile.am (version.h): Changed $^ --> $< in rule for
8099 2002-12-08 Rob Browning <rlb@defaultvalue.org>
8101 * version.h.in (SCM_MICRO_VERSION): use @--@ substitution now.
8102 (SCM_MINOR_VERSION): use @--@ substitution now.
8103 (SCM_MICRO_VERSION): use @--@ substitution now.
8104 (scm_effective_version): new function prototype.
8106 * version.c (scm_effective_version): new function, also add
8109 * Makefile.am (schemelibdir): VERSION -> GUILE_EFFECTIVE_VERSION.
8110 (libpath.h): use GUILE_EFFECTIVE_VERSION to compute
8112 (version.h): generate this here rather than configure.in. This
8113 approach tracks source edits better (i.e. more immediately).
8114 Might be worth considering for other .in files too.
8116 2002-12-02 Marius Vollmer <mvo@zagadka.ping.de>
8118 Reorganized thread package selection. A thread package now only
8119 implements a small set of pthread like functions and Guile
8120 implements the rest on top of that. Guile's implementation is
8121 what the "coop-pthreads" package has been previously. Support for
8122 "coop" threads has been removed until I get time to add it again.
8124 * Makefile.am (libguile_la_SOURCES): Removed iselect.c.
8125 (noinst_HEADERS): Removed coop-threads.c, coop-threads.h, coop.c,
8126 null-threads.c, coop-pthreads.c.
8127 (modinclude_HEADERS): Removed coop-defs.h, coop-pthreads.h. Added
8130 * validate.h (SCM_VALIDATE_THREAD): Moved to threads.h.
8132 * threads.h: Do not include "libguile/coop-defs.h". Include
8133 "libguile/pthread-threads.h" for USE_COPT_THREADS. Removed
8134 (previously deprecated) C level thread API prototypes. They are
8135 now in the thread package specific headers, "null-threads.h" and
8136 "pthread-threads.h".
8137 (SCM_VALIDATE_THREAD, SCM_VALIDATE_MUTEX, SCM_VALIDATE_CONDVAR):
8139 (scm_threads_init): Removed.
8140 (SCM_CRITICAL_SECTION_START, SCM_CRITICAL_SECTION_END,
8141 SCM_THREAD_SWITCHING_CODE, scm_i_switch_counter,
8142 SCM_I_THREAD_SWITCH_COUNT): Define here.
8143 (scm_single_thread_p): Removed.
8144 (scm_call_with_new_thread): Take two args directly instead of list
8146 (scm_i_thread_data, scm_i_set_thread_data, SCM_THREAD_LOCAL_DATA,
8147 SCM_SET_THREAD_LOCAL_DATA): Define here.
8149 * threads.c: Merged with "coop-pthreads.c".
8151 * null-threads.h: Implement pthread-like API as a set of macros.
8153 * pthread-threads.h: New, implement pthread-like API by deferring
8156 * init.c (scm_init_guile_1): Do not call scm_init_iselect, which
8157 has been lost in the reorganization.
8159 2002-12-01 Mikael Djurfeldt <mdj@linnaeus>
8161 The following change makes it possible to move procedure
8162 application dispatch outside inner loops. The motivation was
8163 clean implementation of efficient replacements of R5RS primitives
8166 The semantics is clear: scm_trampoline_N returns an optimized
8167 version of scm_call_N (or NULL if the procedure isn't applicable
8170 Applying the optimization to map and for-each increases efficiency
8171 noticeably. For example, (map abs ls) is 8 times faster than
8174 * eval.h (scm_t_trampoline_1, scm_t_trampoline_2): New types.
8176 * eval.c, eval.h (scm_trampoline_1, scm_trampoline_2): New functions.
8178 * eval.c (call_subr2_2, call_lsubr_2, call_closure_2): New functions;
8179 (map, for-each): Handle also application on two args as a special
8180 case; Use trampolines.
8184 * sort.c (scm_cmp_function): Choose subr2less for scm_tc7_subr_2o;
8185 (subr2oless): Removed.
8186 (scm_restricted_vector_sort_x): Use scm_return_first to keep the
8187 vector GC protected.
8189 * eval.c (check_map_args): Use scm_out_of_range_pos instead of
8192 2002-11-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
8194 * evalext.[ch] (scm_m_undefine, undefine): Deprecated.
8196 2002-11-17 Mikael Djurfeldt <mdj@linnaeus>
8198 * debug.c (scm_make_iloc): Added missing "return".
8200 2002-11-17 Marius Vollmer <mvo@zagadka.ping.de>
8202 * strports.c (scm_eval_string_in_module): Validate second arg to
8203 be a module. Thanks to Arno Peters!
8205 2002-11-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
8207 * .cvsignore: remove goops.c
8209 2002-11-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
8211 * modules.c (scm_env_top_level, scm_lookup_closure_module,
8212 module_variable, scm_module_lookup_closure,
8213 scm_module_transformer, scm_sym2var, scm_module_reverse_lookup,
8214 scm_system_module_env_p): Don't compare SCM values with C
8215 operators == or !=. Avoid SCM_IMP predicates. Prefer !SCM_FALSEP
8218 2002-11-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
8220 * eval.h (SCM_MAKE_ILOC): New macro.
8222 * debug.c (scm_make_iloc): Use SCM_MAKE_ILOC instead of computing
8223 the iloc bitpattern here.
8225 2002-11-14 Mikael Djurfeldt <mdj@linnaeus>
8227 * coop-pthreads.c, coop-pthreads.h: scm_internal_select should be
8228 part of the API, otherwise it's difficult to write Guile
8229 extensions using non-blocking I/O => moved #include
8230 "libguile/iselect.h" from coop-pthreads.c --> coop-pthreads.h.
8232 * coop-pthreads.c (scm_unlock_mutex): Changed s_lock_mutex -->
8235 2002-11-10 Marius Vollmer <mvo@zagadka.ping.de>
8237 * __scm.h (USE_THREADS, GUILE_ISELECT): Do not define here. They
8238 are defined in configure.in.
8240 * threads.c: Removed SCM_API from function definitions. SCM_API
8241 is only for declarations.
8243 2002-11-07 Mikael Djurfeldt <mdj@linnaeus>
8245 * coop-pthreads.h: Added support for thread specific data to the
8246 generic C API for the coop-pthreads case.
8248 * threads.c, threads.h (scm_cond_init): Undo unintentional API
8250 (scm_cond_broadcast): Added missing function.
8252 2002-11-04 Marius Vollmer <marius.vollmer@uni-dortmund.de>
8254 * coop.c (coop_next_runnable_thread): Removed, wich should have
8255 happened when GUILE_ISELECT was hard-wired.
8257 2002-11-03 Marius Vollmer <mvo@zagadka.ping.de>
8259 * Makefile.am (libguile_la_SOURCES): Added threads.c
8260 (DOT_DOC_FILES): Added threads.doc.

8262 (EXTRA_libguile_la_SOURCES): Removed threads.c.
8263 (noinst_HEADERS): Added coop-pthreads.c.
8264 (modinclude_HEADERS): Added coop-pthreads.h.
8266 * __scm.h (USE_THREADS, GUILE_ISELECT): Define when
8267 SCM_DEBUG_DEPRECATED. Removed their use thru-out Guile.
8269 * iselect.c: Include "_scm.h" before testing HAVE_UNISTD_H.
8270 Thanks to Bill Schottstaedt!
8272 * numbers.c (scm_integer_expt): Make 0^z == 0 for z != 0.
8274 * _scm.h (HAVE_RESTARTABLE_SYSCALLS): Do define even when
8275 SCM_COPT_THREADS is defined.
8276 (SCM_SYSCALL): Use EINTR-expection version when SCM_COPT_THREADS
8279 * coop-pthreads.c: Some harmless renamings of internal stuff.
8280 (create_thread): New, generalized version of
8281 scm_call_with_new_thread.
8282 (scm_call_with_new_thread): Use it.
8283 (scm_spawn_thread): New, use create_thread.
8285 2002-11-02 Marius Vollmer <mvo@zagadka.ping.de>
8287 * coop-pthreads.c, coop-pthreads.h: Redone completely, you might
8288 start testing it now.
8290 * _scm.h: Include <errno.h< so that SCM_SYSCALL is correctly
8291 defined when HAVE_RESTARTABLE_SYSCALLS is not defined.
8292 (HAVE_RESTARTABLE_SYSCALLS): Do not define when USE_COPT_THREADS
8295 2002-10-27 Marius Vollmer <mvo@zagadka.ping.de>
8297 * scmsigs.c (signal_cell_handlers, install_handler_data,
8298 scm_delq_spine_x, really_install_handler, install_handler): New
8299 scheme for triggering signal handlers, to simplify take_signal.
8300 (take_signal): Simplified, to avoid race conditions.
8301 (scm_sigaction_for_thread): Use new Scheme. Validate that thread
8304 * async.c (scm_async_click): Reset pending_asyncs, handle
8305 signal_asyncs. Don't set cdr of a non-signal async to #f.
8306 (scm_i_queue_async_cell): Do not check cdr of cell for #f, queue
8307 always. Set pending_asyncs.
8308 (scm_system_async_mark_for_thread): Check that thread has not
8310 (scm_unmask_signals, decrease_block): Call scm_async_click after
8311 block_asyncs becomes zero.
8313 * __scm.h (SCM_ASYNC_CLICK): Check pending_asyncs instead of
8316 * root.h (scm_root_state): Added pending_asyncs and signal_asyncs
8318 * root.c (root_mark): Mark them.
8319 (make_root): Initialize them.
8321 * iselect.c, iselect.h: Replaced GUILE_ISELECT with
8323 (scm_internal_select): Define one version for USE_COOP_THREADS and
8324 one for USE_NULL_THREADS.
8325 (scm_init_iselect): Likewise.
8327 * inline.h (scm_cell, scm_double_cell): Also allow
8328 USE_COPT_THREADS to not protect the slot initializers.
8330 * init.c (scm_init_guile_1): Call scm_init_thread_procs. This is
8331 because threads need to be initialized before the stack, but
8332 gsubrs such as scm_timed_condition_variable_wait can only be
8335 * threads.h: Include "coop-pthreads.h" when requested.
8336 (scm_threads_make_mutex, scm_threads_lock_mutex,
8337 scm_threads_unlock_mutex, scm_threads_monitor): Removed, they were
8338 not implemented anyway.
8339 (scm_init_thread_procs, scm_try_mutex,
8340 scm_timed_condition_variable_wait,
8341 scm_broadcast_condition_variable, scm_c_thread_exited_p,
8342 scm_thread_exited_p): New prototypes.
8343 (struct timespec): Define if not already defined.

8345 scm_mutex_unlock, scm_mutex_destroy, scm_t_cond, scm_cond_init,
8346 scm_cond_wait, scm_cond_timedwait, scm_cond_signal,
8347 scm_cond_broadcast, scm_cond_destroy): Declarations moved here and

8879 Document cases where SCM_WRITABLE_VELTS() is used.
8881 * vectors.h (SCM_VELTS): prepare for write barrier, and let
8882 SCM_VELTS() return a const pointer
8883 (SCM_VECTOR_SET): add macro.
8885 2002-07-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
8887 * eval.c (SCM_CEVAL), macros.c (macro_print, scm_makmacro,
8888 scm_sym_macro, scm_macro_type), macros.h (scm_makmacro):
8889 Deprecated the special kind of built-in dynamic syntax transformer
8890 that was inaccurately named "macro". Note: The built-in syntax
8891 transformers that are named "mmacro" or "memoizing-macro" still
8892 exist, and it is these which come much closer to what one would
8895 2002-07-13 Neil Jerram <neil@ossau.uklinux.net>
8897 * eval.c (unmemocopy): Fix for
8898 1001-local-eval-error-backtrace-segfaults (unmemoization crash
8899 with internal definitions and local-eval).
8901 2002-07-12 Gary Houston <ghouston@arglist.com>
8903 * dynl.c: Don't define stub procedures if DYNAMIC_LINKING is not
8904 defined. They don't do anything useful, especially since the
8905 only case where DYNAMIC_LINKING is undefined seems to be
8906 when --with-modules=no is given to configure, which is basically
8907 requesting that the "dynamic linking module" be omitted.
8909 * Makefile.am (libguile_la_SOURCES): move dynl.c from
8910 libguile_la_SOURCES to EXTRA_libguile_la_SOURCES.
8912 * extensions.c (load_extension): check DYNAMIC_LINKING for
8914 * init.c (scm_init_guile_1): check DYNAMIC_LINKING for
8915 scm_init_dynamic_linking.
8917 2002-07-10 Marius Vollmer <mvo@zagadka.ping.de>
8919 * guile.c, iselect.h, net_db.c, posix.c, socket.c: No need to
8920 check for Cygwin when including <winsock2.h>, this is already
8921 check for by configure. Thus, revert change from 2002-07-07.
8923 2002-07-10 Gary Houston <ghouston@arglist.com>
8925 * eq.c: include <string.h>
8926 * dynl.c: docstring editing.
8928 2002-07-09 Gary Houston <ghouston@arglist.com>
8930 * dynl.c (scm_dynamic_call): docstring editing.
8932 2002-07-08 Rob Browning <rlb@defaultvalue.org>
8934 * gc_os_dep.c: HURD fixes.
8936 2002-07-07 Marius Vollmer <mvo@zagadka.ping.de>
8938 Crosscompiling and Cygwin fixes by Jan Nieuwenhuizen. Thanks!
8940 * Makefile.am: Override default rule for c-tokenize.$(OBJECT);
8941 this should be compiled for BUILD host.
8942 Override default rule for
8943 guile_filter_doc_snarfage$(EEXECT); this should run on BUILD host.
8944 Add missing $(EXEEXT) to guile_filter_doc_snarfage invocation.
8945 (snarf2checkedtexi): Use GUILE_FOR_BUILD instead of preinstguile.
8947 * guile.c, iselect.h, net_db.c, posix.c, socket.c: Do not include
8948 <winsock2.h> on Cygwin even when we have it.
8950 2002-07-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
8952 * __scm.h (SCM_CAUTIOUS), eval.c (scm_eval_args, deval_args,
8953 SCM_CEVAL): Removed compile time option SCM_CAUTIOUS to clean up
8954 the code. Full number of arguments checking of closures is
8955 mandatory now. However, the option to disable the checking has
8956 most probably not been used anyway.
8958 2002-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
8960 * __scm.h (SCM_RECKLESS), backtrace.c (SCM_ASSERT), debug.c
8961 (scm_debug_options), eval.c (scm_lookupcar, scm_lookupcar1,
8962 scm_badargsp, SCM_CEVAL, SCM_APPLY, scm_map, scm_for_each),
8963 feature.c (scm_init_feature), gsubr.c (scm_gsubr_apply), numbers.c
8964 (scm_logand, scm_logior, scm_logxor, scm_i_dbl2big), srcprop.c
8965 (scm_source_properties, scm_set_source_properties_x,
8966 scm_source_property): Removed compile time option SCM_RECKLESS to
8967 clean up the code. Full number of arguments checking of closures
8968 is mandatory now. However, the option to disable the checking has
8969 most probably not been used anyway.
8971 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
8972 scm_source_property): Use !SCM_CONSP instead of SCM_NCONSP.
8974 2002-06-30 Gary Houston <ghouston@arglist.com>
8976 * dynl.c: Removed all SCM_DEFER_INTS/SCM_ALLOW_INTS, which won't
8977 do anything useful. Added a comment about need for a mutex if
8978 pre-emptive threading is supported.
8980 * posix.c (scm_convert_exec_args), dynl.c
8981 (scm_make_argv_from_stringlist): static procs: 1) renamed both to
8982 allocate_string_pointers. 2) simplified: don't reallocate the
8983 strings, just make an array of pointers 3) avoid memory leaks on
8984 error 4) let the procedure report errors in its own name.
8985 Consequences: 1) the procedures now assume that SCM strings are
8986 nul-terminated, which should always be the case. 2) Since strings
8987 are not reallocated, it's now possible for strings passed to
8988 dynamic-args-call to be mutated.
8990 2002-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
8992 * __scm.h, eval.c, eval.h: Removed compile time option
8993 MEMOIZE_LOCALS to clean up the code. Now, caching of local
8994 variable positions during memoization is mandatory. However, the
8995 option to disable the caching has most probably not been used
8998 2002-06-18 Marius Vollmer <mvo@zagadka.ping.de>
9000 * print.c (scm_simple_format): Print missing part of format before
9001 ~% control. Thanks to Daniel Skarda!
9003 2002-06-01 Marius Vollmer <mvo@zagadka.ping.de>
9005 * mkstemp.c: Added exception notice to license statement.
9007 2002-05-22 Marius Vollmer <mvo@zagadka.ping.de>
9009 * numbers.c (mem2ureal): When returning an inexact zero, make sure
9010 it is represented as a floating point value so that we can change
9013 From John W. Eaton <jwe@bevo.che.wisc.edu>
9015 * numbers.c (idbl2str): Don't omit sign when printing negative zero.
9017 2002-05-14 Thien-Thi Nguyen <ttn@giblet.glug.org>
9019 * gc_os_dep.c: For I386/OPENBSD, allow for `__i386__'
9020 in addition to `i386'. Thanks to Dale P. Smith.
9022 2002-05-08 Marius Vollmer <mvo@zagadka.ping.de>
9024 * eq.c (real_eqv): New.
9025 (scm_eqv_p): Use it when comparing reals and complexes.
9027 * numbers.c: Include <string.h>, for strncmp.
9028 (mem2complex): Do not create negative NaNs.
9029 (scm_leq_p, scm_geq_p): Explicitely return #f when comparing a
9031 (scm_inexact_to_exact): Signal error when converting a NaN.
9033 2002-05-06 Marius Vollmer <mvo@zagadka.ping.de>
9035 * posix.c (scm_putenv): Handle removing variables explicitely by
9040 * numbers.h: Conditionally include floatingpoint.h, ieeefp.h, and
9041 nan.h. Provide declarations for scm_inf_p, scm_nan_p, scn_inf,
9043 * numbers.c: [SCO && ! HAVE_ISNAN] (isnan): New function.
9044 [SCO && ! HAVE_ISINF] (isinf): New function.
9045 (xisinf, xisnan): New functions.
9047 (isfinite): Define in terms of xisinf.
9048 (scm_inf_p, scm_nan_p): New functions.
9049 (guile_Inf, guile_NaN): New file-scope vars.
9050 (guile_ieee_init): New function.
9051 (scm_inf, scm_nan): New functions.
9052 (idbl2str): Handle Inf and NaN. Remove funny label and
9053 corresponding gotos.
9054 (ALLOW_DIVIDE_BY_ZERO): New macro.
9055 (scm_divide): Allow division by zero to occur if
9056 ALLOW_DIVIDE_BY_ZERO is defined.
9057 Handle bignums and ints as special cases.
9059 Additional stuff by me:
9061 numbers.c (mem2ureal): Recognize "inf.0" and "nan.xxx".
9062 (scm_even_p, scm_odd_p): Treat infinity as even and odd.
9063 (iflo2str): Don't output a '+' for negative numbers or for Inf and
9064 NaN. They will provide their own sign.
9065 (scm_divide): Only allow divides by inexact zeros. Dividing by
9066 exact zeros still signals an errors.
9068 2002-04-22 Thien-Thi Nguyen <ttn@giblet.glug.org>
9070 * goops.h (scm_slot_exists_p): Rename from scm_slots_exists_p.
9071 * goops.c (scm_slot_exists_p): Rename from scm_slots_exists_p.
9072 (scm_slot_exists_p): Rename from scm_slots_exists_p.
9073 Thanks to Andreas Rottmann.
9075 2002-04-20 Gary Houston <ghouston@arglist.com>
9077 * removal of unused fields in root state (thanks to Christopher
9078 Cramer for pointing out the disuse.)
9079 * root.h (scm_root_state): removed def_inp, def_outp, def_errp.
9080 (scm_def_inp, scm_def_outp, scm_def_errp): removed.
9082 * root.c (root_mark): don't mark them.
9083 (scm_make_root): don't set them to #f.
9084 * init.c (scm_init_standard_ports): don't initialise with the
9087 2002-04-17 Marius Vollmer <mvo@zagadka.ping.de>
9089 * Makefile.am (EXTRA_DIST): Added cpp_err_symbols.c and
9092 2002-04-16 Marius Vollmer <mvo@zagadka.ping.de>
9094 * guile-snarf.in: Do not clean input file. This would write to
9095 the $(srcdir) during a VPATH build, which is not allowed. It also
9096 isn't needed since it only works when an output filename has been
9097 specified and in that case we don't need to clean the input file
9098 because the output file will already exist.
9100 2002-03-31 Marius Vollmer <mvo@zagadka.ping.de>
9102 * guile-snarf: Install the trap for removing $cleanfile only when
9103 the value of $cleanfile is actually known.
9105 2002-04-10 Rob Browning <rlb@defaultvalue.org>
9107 * .cvsignore: add versiondat.h and *.c.clean.c.
9109 2002-03-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
9111 * srcprop.[ch] (scm_c_source_property_breakpoint_p): New
9112 function, replaces macro SRCBRKP.
9114 (SRCBRKP): Deprecated.
9116 * eval.c (SCM_CEVAL): Replaced use of SRCBRKP by call to
9117 scm_c_source_property_breakpoint_p. Removed some use of arg1 as
9120 2002-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
9122 * debug.h, eval.c: Deprecated CHECK_ENTRY, CHECK_APPLY and
9123 CHECK_EXIT and removed all references to them.
9125 2002-03-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
9127 * debug.h (scm_ready_p, debug_print): Removed declarations.
9129 * eval.c (EVALCELLCAR): Removed.
9131 (SCM_CEVAL): Eliminated label loopnoap. Removed side-effecting
9132 operation from condition.
9134 2002-03-24 Marius Vollmer <mvo@zagadka.ping.de>
9136 * guile-snarf.in: When the output filename is "-", write to
9137 stdout. When no "-o" option is given, use "-" as the output
9138 filename (i.e., stdout). Only 'clean' the inputfile or remove the
9139 output file on error when the output file name is not "-". Define
9140 the preprocessor macro SCM_MAGIC_SNARFER while snarfing.
9142 * Makefile.am (.c.x): Pass "-o $@" to guile-snarf.
9144 2002-03-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
9146 * eval.c (SCM_CEVAL, SCM_APPLY): Eliminated labels wrongnumargs
9147 and the corresponding goto statements. Removed redundant code.
9149 2002-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
9151 * eval.c (SCM_CEVAL): Minimized scope of variable arg2.
9152 Eliminated redundant SCM_IMP check. Exlined call to EVALCAR.
9153 Re-enabled handing of rpsubrs and asubrs.
9155 2002-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
9157 * eval.c (SIDEVAL): Removed.
9159 (SCM_CEVAL): Minimized scope of variable orig_sym. Eliminated
9160 goto-labels cdrxnoap, cdrxbegin and nontoplevel_cdrxnoap. Changed
9161 argument checking order for set! to locals, variables and symbols.
9162 Improvements to control structure. Removed some uses of arg1 and
9163 arg2 as temporary variables.
9165 2002-03-15 Thien-Thi Nguyen <ttn@giblet.glug.org>
9167 * guile-snarf.in: Remove "--compat=1.4" support.
9168 Add "-d" and "-D" support.
9170 (deprecated_list): New var.
9171 (compat_mode_clean_xxx): Delete.
9172 (grep_deprecated): New func.
9173 ("main"): If "-d" or "-D", call `grep_deprecated'.
9175 2002-03-15 Neil Jerram <neil@ossau.uklinux.net>
9177 * hooks.h: Change scm_t_c_hookype_t everywhere to
9182 * strings.c (scm_string_p): Change unnecessary `iff' to `if'.
9184 * ports.c (scm_sys_make_void_port): Use `@file'.
9186 * numbers.c (scm_number_p, scm_real_p): Use `otherwise' rather
9189 * macros.c (scm_makmacro): Don't say that the form replaces its
9190 source, because it doesn't.
9191 (scm_makmmacro): Clarify difference between this and scm_makmacro.
9193 * backtrace.c (scm_display_error), filesys.c (scm_umask,
9194 scm_select, scm_basename), goops.c (scm_method_generic_function),
9195 numbers.c (scm_integer_length), posix.c (scm_getgroups, scm_execl,
9196 scm_setlocale, scm_flock), socket.c (scm_shutdown): Correct
9199 * debug.c (scm_debug_options), eval.c
9200 (scm_eval_options_interface), read.c (scm_read_options): Change
9201 incorrect @var in docstring to @code.
9203 2002-03-14 Marius Vollmer <mvo@zagadka.ping.de>
9205 * unif.c (singp): Use SCM_REALP instead of SCM_SLOPPY_REALP.
9207 * snarf.h (SCM_SNARF_INIT): Add "^:^" after code so that
9208 guile-snarf can remove trailing non-init code.
9210 * guile-snarf.in (modern_snarf): Remove everything following and
9211 including "^:^" from the output.
9213 2002-03-14 Dirk Herrmann <D.Herrmann@tu-bs.de>

9221 * guile-snarf.in: Update copyright.
9222 Rewrite to internalize error handling.
9223 Add "--compat=1.4" handling.
9226 * Makefile.am (libpath.h): Use @top_srcdir_absolute@.
9227 (snarfcppopts): New var.
9228 (.c.x): Use $(snarfcppopts). Rework guile-snarf usage.
9229 (.c.doc): Use $(snarfcppopts).
9231 * alist.c, arbiters.c, async.c, backtrace.c, boolean.c, chars.c,
9232 continuations.c, debug-malloc.c, debug.c, deprecation.c, dynl.c,
9233 dynwind.c, environments.c, eq.c, error.c, eval.c, evalext.c,

9243 unif.c, values.c, variable.c, vectors.c, version.c, vports.c,
9244 weaks.c: Retire inclusion guard macro SCM_MAGIC_SNARFER.
9246 2002-03-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
9248 * eval.c (SCM_CEVAL): Got rid of the last reference to t.lloc.
9249 The next step will be to remove the union 't' and simplify the
9250 code of SCM_CEVAL that way.
9252 2002-03-12 Neil Jerram <neil@ossau.uklinux.net>
9254 * iselect.c (collisionp, gnfds, greadfds, gwritefds, gexceptfds,
9255 rreadfds, rwritefds, rexceptfds): Made static.
9257 * gc.c (terminating), fports.c (terminating): Renamed
9260 2002-03-11 Marius Vollmer <mvo@zagadka.ping.de>
9262 * numbers.c (scm_divide): Adapt code from libstdc++/f2c to void
9263 potential overflow problems. Thanks to John W Eaton!
9265 * strop.c (string_capitalize_x): Treat characters as unsigned so
9266 that 8-bit chars work. Thanks to David Pirotte!
9268 2002-03-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
9270 * eval.c (SCM_CEVAL): Cleaned up the handling of 'slot-ref',
9271 'slot-set!' and 'nil-cond'. Removed some uses of t.arg1, arg2 and
9272 proc as temporary variables. Introduced temporary variables with
9273 hopefully descriptive names for clarification. Replaced SCM_N?IMP
9274 by a more explicit predicate in some places.
9276 2002-03-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
9278 * eval.c (SCM_CEVAL): Cleaned up the handling of #@dispatch.
9279 Added lots of comments regarding the implementation of #@dispatch.
9280 Changed intra-procedure communication to use t.arg1 instead of
9281 arg2. Removed some uses of t.arg1, t.lloc and proc as temporary
9282 variables. Introduced temporary variables with hopefully
9283 descriptive names for clarification. Replaced SCM_N?IMP by a more
9284 explicit predicate in some places. Use SCM_INSTANCE_HASH instead
9285 of computing the expression explicitly. Eliminate now unused
9286 label nontoplevel_cdrxbegin.
9288 * goops.h (SCM_INSTANCE_HASH): New macro.
9290 * objects.h (SCM_CMETHOD_FORMALS, SCM_CMETHOD_BODY): New macros.
9292 2002-03-08 Thien-Thi Nguyen <ttn@giblet.glug.org>
9294 * Makefile.am (bin_SCRIPTS): Revive this decl, w/ initial element
9295 "guile-snarf" moved back from `noinst_SCRIPTS'.
9297 2002-03-08 Neil Jerram <neil@ossau.uklinux.net>
9299 * srcprop.c (scm_set_source_property_x): If SRCPROPS obj already
9300 exists when adding a source property other than those that are
9301 handled explicitly, add the new property to the SRCPROPS obj's
9304 * debug.h (SCM_MAX_FRAME_SIZE): Remove incorrect comment about use
9305 of SCM_MAX_FRAME_SIZE as a bit mask; it isn't used like this.
9307 * eval.c (SCM_CEVAL): Don't store scm_debug_eframe_size in
9308 debug.status. It isn't needed, and it can overflow the bits
9309 reserved for it (which may lead to a segv or a GC abort).
9311 2002-03-02 Dirk Herrmann <D.Herrmann@tu-bs.de>
9313 * eval.c (SCM_CEVAL): Cleaned up the handling of 'apply'. Removed
9314 side-effecting operations from conditions and macro calls.
9315 Replaced SCM_N?IMP by a more explicit predicate in some places.
9316 Minimized the scope of some variables.
9318 2002-03-02 Stefan Jahn <stefan@lkcc.org>
9320 * convert.i.c: Fixed int <-> long conversions which would have
9321 failed if their sizes were different.
9323 2002-03-02 Dirk Herrmann <D.Herrmann@tu-bs.de>
9325 * eval.c (SCM_CEVAL): Cleaned up the handling of 'if', 'let',
9326 'letrec' and 'set*': Removed some uses of t.arg1, t.lloc and proc
9327 as temporary variables. Removed side-effecting operations from
9328 conditions and macro calls. Introduced temporary variables with
9329 hopefully descriptive names for clarification. Replaced SCM_N?IMP
9330 by a more explicit predicate in some places. Removed code that
9331 was conditionally compiled if SICP was defined - which it never
9334 2002-03-02 Dirk Herrmann <D.Herrmann@tu-bs.de>
9336 * eval.c (SCM_CEVAL): Cleaned up the handling of 'cons' and 'do':
9337 Removed some uses of t.arg1 and proc as temporary variables.
9338 Removed side-effecting operations from conditions and macro calls.
9339 Introduced temporary variables with hopefully descriptive names
9340 for clarification. Replaced SCM_N?IMP by a more explicit
9341 predicate in some places.
9343 2002-03-02 Dirk Herrmann <D.Herrmann@tu-bs.de>
9345 * eval.c (scm_badargsp, SCM_CEVAL): Replaced SCM_N?IMP by a more
9346 explicit predicate in some places.
9348 (CHECK_EQVISH): Removed.
9350 (SCM_CEVAL): Removed some uses of t.arg1 and proc as temporary
9351 variables. Removed side-effecting operations from conditions and
9352 macro calls. Introduced temporary variables for clarification.
9353 Sorted if-else-if check for the type of the last form in a list by
9354 frequency. Avoided some unnecessary tail-recursion calls.
9356 2002-03-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
9358 * gc.c (SCM_HEAP_SEG_SIZE, CELL_UP, CELL_DN, NEXT_DATA_CELL,
9359 init_heap_seg, alloc_some_heap), gc.h (struct scm_cell, struct
9360 scm_t_cell, SCM_CELLPTR, SCM_GC_CARD_SIZE,
9361 SCM_GC_IN_CARD_HEADERP), tags.h (SCM_CELLP): Renamed the struct
9362 scm_cell and all its uses to scm_t_cell in accordance to Guile's
9363 naming scheme for types.
9365 * alist.c (scm_acons), convert.i.c (CTYPES2UVECT,
9366 CTYPES2UVECT_OPTIONAL), coop-threads.c (scm_call_with_new_thread,
9367 scm_spawn_thread), debug.c (scm_make_debugobj), environments.c
9368 (scm_make_environment), eval.c (scm_closure), fports.c

9860 (iqq): Added a comment. Changed the depth parameter to
9861 unsigned. Use size_t for vector lengths. Make sure vector object
9862 is gc protected as long as its contents are read. Add some syntax
9863 checks. Get rid of unnecessary SCM_IMP test. Clean up the
9864 control structure a bit.
9866 (scm_m_delay): Added comment about the implementation of
9869 (scm_m_define): Add comment about guile's currying define
9870 syntax. Renamed 'proc' to 'name'. Eliminate dependency on macro
9871 DEBUG_EXTENSIONS. Simplified code a bit. Eliminate SICP code.
9873 (scm_m_letrec1): Removed. Part of the functionality is taken
9874 over by the new function 'transform_bindings'.
9876 (transform_bindings): New function. Takes over some of the
9877 functionality of removed function 'scm_m_letrec1', namely to split
9878 a list of bindings into a reversed list of variables and a list of
9881 (scm_m_letrec): Call 'transform_bindings'.
9883 (scm_m_let): Minimized scope of local variables. Renamed 'proc'
9884 to 'temp' and 'arg1' to 'binding'. Eliminated redundant SCM_NIMP
9885 test. Use 'transform_bindings'. Fixed scoping error with named
9886 let (Thanks to Aubrey Jaffer for reporting the bug and to Neil
9887 Jerram for suggesting the fix). Cleaned up the control structure
9890 (scm_m_expand_body): Use 'transform_bindings'. Eliminated
9891 unnecessary consing. Eliminated unnecessary
9892 SCM_DEFER/ALLOW_INTS.
9894 (SCM_CEVAL): Un-obfuscated some loops.
9896 2001-11-16 Neil Jerram <neil@ossau.uklinux.net>
9898 * gc.h (scm_unhash_name): Old declaration removed.
9900 * eval.c (s_scm_eval): Change @var{primitive-eval} to
9901 @code{primitive-eval}.
9903 * feature.c, vectors.c, net_db.c, unif.c, weaks.c, struct.c,
9904 version.c, alist.c, ports.c, ramap.c, unif.c, strings.c, list.c:
9905 Change @deffnx lines in docstrings to say {Scheme Procedure}
9906 rather than primitive or procedure.
9908 * posix.c (scm_execl), filesys.c (scm_close), unif.c
9909 (scm_array_set_x, scm_array_contents, scm_uniform_array_read_x,
9910 scm_bit_set_star_x, scm_bit_invert_x), ramap.c (scm_array_fill_x,
9911 scm_array_for_each, scm_array_index_map_x), vectors.c (scm_vector,
9912 scm_make_vector, scm_vector_to_list, scm_vector_fill_x), strop.c
9913 (scm_string_split, scm_string_ci_to_symbol), strings.c
9914 (scm_string_p), sort.c (scm_merge), print.c (scm_newline),
9915 macros.c (scm_macro_type), alist.c (scm_acons, scm_assq):
9916 Docstring fixes and improvements reflecting edits that have been
9917 made in the reference manual source.
9919 * objprop.c (scm_object_properties, scm_set_object_properties_x,
9920 scm_object_property, scm_set_object_property_x): Remove invalid
9921 @deffnx lines for corresponding procedure property primitives.
9923 These changes add a @deffnx C function declaration and function
9924 index entries for each Guile primitive to the copy of the doc
9925 snarf output that is used for reference manual synchronization.
9926 Online help is unchanged.
9928 * snarf.h (SCM_SNARF_DOCS): Output primitive's C function name.
9929 (SCM_DEFINE, SCM_DEFINE1, SCM_REGISTER_PROC): Supply to C function
9930 name to SCM_SNARF_DOCS.
9932 * guile-snarf-docs-texi.in: Pass the shell script's arguments into
9933 snarf-check-and-output-texi.
9935 * Makefile.am (guile-procedures.texi): New rule.
9936 (BUILT_SOURCES, guile.texi, guile-procedures.txt, CLEANFILES):
9937 Changed so that the last stage of doc snarfing is now performed
9938 twice, once to produce guile-procedures.txt for online help, and
9939 once to produce guile.texi for reference manual synchronization.
9941 2001-11-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
9943 * eval.c (RETURN): Wrap in do{}while(0) in order to make it
9944 safely usable as a single statement followed by a ';', for example
9947 (SCM_CEVAL, SCM_APPLY): Clean up code using 'RETURN'.
9949 2001-11-13 Neil Jerram <neil@ossau.uklinux.net>
9951 * random.c (scm_random_solid_sphere_x,
9952 scm_random_hollow_sphere_x): Correct "shere" typos.
9954 * hashtab.c (scm_hash_fold): Add missing apostrophe to docstring.
9956 * version.c (scm_version): Update docstring to include
9959 2001-11-13 Marius Vollmer <mvo@zagadka.ping.de>
9961 * modules.c (scm_c_export): Call va_end after collecting the
9964 * strop.h, strop.c (scm_substring_move_left_x,
9965 scm_substring_move_right_x): Removed.
9967 * __scm.h (HAVE_UINTPTR_T, HAVE_PTRDIFF_T, HAVE_LONG_LONG,
9968 HAVE_LONG_LONGS): Define to "1" when defining them, to mirror what
9971 2001-11-12 Marius Vollmer <mvo@zagadka.ping.de>
9973 * numbers.c: Document macros to define when including
9974 num2integral.i.c. MAX_VALUE and MIN_VALU are no longer used, we
9975 now rely on SIZEOF_ macros that have been figured out at
9978 * num2integral.i.c: Adapt to new interface.
9979 (NUM2INTEGRAL): Test whether a fixnum can be represented in the
9980 target type by casting it and checking whether it is still the
9981 same. Do not try to handle bignums for integral types that are
9982 smaller than fixnums. When handling bignums, collect the
9983 magnituse first into a unsigned type, and correctly check for
9985 (INTEGRAL2BIG): Do not use MIN_VALUE explicitely by observing that
9986 only -MIN_VALUE can still be negative of all negative numbers (in
9989 * tags.h (SIZEOF_SCM_T_BITS): Define it appropriately.
9991 * __scm.h: Define HAVE_UINTPTR_T, HAVE_PTRDIFF_T and
9992 HAVE_LONG_LONG depending on whether their size is non-zero.
9994 2001-11-11 Thien-Thi Nguyen <ttn@glug.org>
9996 * strop.c (scm_string_null_p): Docfix; nfc.
9997 Thanks to Scott Lenser.
9999 2001-11-07 Neil Jerram <neil@ossau.uklinux.net>
10001 * extensions.c (scm_load_extension): Canonicalize docstring
10004 * unif.c (scm_uniform_array_write), ports.c
10005 (scm_current_output_port, scm_force_output), dynwind.c
10006 (scm_dynamic_wind), scmsigs.c (scm_setitimer, scm_getitimer),
10007 filesys.c (scm_open, scm_lstat), struct.c
10008 (scm_make_struct_layout), random.c (scm_random,
10009 scm_random_solid_sphere_x, scm_random_hollow_sphere_x, strop.c
10010 (scm_i_index): Remove superfluous whitespace from end of docstring
10013 * filesys.c (scm_select), guardians.c (scm_guardian_greedy_p),
10014 strings.c (scm_make_string), variable.c (scm_make_variable,
10015 scm_make_undefined_variable, scm_variable_p, scm_variable_set_x,
10016 scm_variable_bound_p), scmsigs.c (scm_setitimer, scm_getitimer),
10017 posix.c (scm_crypt), struct.c (scm_make_vtable_vtable), hashtab.c
10018 (scm_hash_fold), ports.c (scm_port_for_each): Remove superfluous
10019 newline at end of docstrings.
10021 * modules.c (scm_set_current_module): Add missing newline to
10024 2001-11-07 Stefan Jahn <stefan@lkcc.org>
10026 * win32-socket.[ch]: New files. Defines Winsock-API error codes
10027 and makes them available through Guile. That is because the
10028 Winsock-API does not store its errors in `errno' and thus cannot
10029 return error messages via `strerror (errno)'.
10031 * socket.c (scm_init_socket): Initialize `win32-socket' part
10032 here under M$-Windows.
10034 * numbers.h: Added missing declaration of
10035 `scm_sys_check_number_conversions()'.
10037 * error.c: Local definition of SCM_I_STRERROR and SCM_I_ERRNO
10038 and use in `(strerror)' and `(system-error)'.
10040 * Makefile.am (EXTRA_libguile_la_SOURCES): Added
10041 `win32-socket.[ch]' to extra source and header files.
10043 2001-11-06 Marius Vollmer <mvo@zagadka.ping.de>
10045 * script.c (scm_shell_usage, scm_compile_shell_switches): Prepend
10046 a call to turn-on-debugging when --debug has been given instead of
10047 turning it on directly. Also, handle new `--no-debug' option,
10048 which might suppress the call to turn-on-debugging.
10050 2001-11-05 Stefan Jahn <stefan@lkcc.org>
10052 * struct.c (s_scm_struct_vtable_p): Corrected docstring.
10054 2001-11-04 Stefan Jahn <stefan@lkcc.org>
10056 * Makefile.am (libguile_la_LIBADD): Added $(THREAD_LIBS_LOCAL)
10057 here (was at guile_LDADD) which describes the dependency
10058 correctly and allows a clean build on Win32.
10060 * __scm.h (SCM_API): Follow-up patch. Renamed __FOO__ macros
10063 * __scm.h: USE_DLL_IMPORT indicates the usage of the DLL
10064 import macros for external libraries (libcrypt, libqthreads,
10065 libreadline and libregex).
10067 * coop-defs.h: Include <winsock2.h> for `struct timeval'.
10069 * posix.c (flock): Added support for flock() in M$-Windows.
10071 * guile.c (SCM_IMPORT): Follow-up patch. Use SCM_IMPORT instead
10074 * fports.c (getflags): Differentiate reading and writing pipes
10077 * filesys.c (S_IS*): Redefine all of the S_IS*() macros for
10080 * coop.c (coop_condition_variable_timed_wait_mutex): Use
10081 conditionalized error code if `ETIMEDOUT' is not available.
10082 (scm_thread_usleep): Remove bogus declaration of `struct timeval
10085 * numbers.c (PTRDIFF_MIN): Moved this definition where it actually
10086 belongs. That is because NO_PREPRO_MAGIC gets undefined after
10087 each inclusion of `num2integral.i.c'.
10088 (SIZE_MAX): Define NO_PREPRO_MAGIC if SIZE_MAX is undefined.
10090 2001-11-03 Marius Vollmer <mvo@zagadka.ping.de>
10092 * eval.c (scm_m_begin): Allow `(begin)`, with no subforms.
10093 (SCM_CEVAL): Evaluate an empty `begin' to SCM_UNSPECIFIED.
10095 2001-11-02 Mikael Djurfeldt <mdj@linnaeus>
10097 * print.c (scm_iprin1): Mark print state as revealed when
10098 dispatching to generic write or display.
10100 * unif.c (scm_ra2contig): Fixed memory overwrite bug.
10102 2001-11-02 Marius Vollmer <mvo@zagadka.ping.de>
10104 Support for native Win32. Thanks to Stefan Jahn!
10106 * Makefile.am: Add win32-uname.c, win32-uname.h, win32-dirent.c
10107 and win32-dirent.h to extra source and header files. These
10108 include the uname() and the POSIX dirent interface implementation
10109 for M$-Windows. Put `-no-undefined' into LDFLAGS to support
10110 linkers which do not allow unresolved symbols inside shared
10111 libraries. Corrected `guile_filter_doc_snarfage$(EXEEXT)'
10114 * __scm.h: Defined SCM_API. This macro gets prepended to all
10115 function and data definitions which should be exported or imported
10116 in the resulting dynamic link library in the Win32 port.
10118 * __scm.h, alist.h, arbiters.h, async.h, backtrace.h, boolean.h,
10119 chars.h, continuations.h, coop-defs.h, coop-threads.h,
10120 debug-malloc.h, debug.h, deprecation.h, dynl.h, dynwind.h,
10121 environments.h, eq.h, error.h, eval.h, evalext.h, extensions.h,
10122 feature.h, filesys.h, fluids.h, fports.h, gc.h, gdb_interface.h,
10123 gdbint.h, gh.h, goops.h, gsubr.h, guardians.h, hash.h, hashtab.h,

10128 read.h, regex-posix.h, root.h, rw.h, scmsigs.h, script.h, simpos.h,
10129 smob.h, socket.h, sort.h, srcprop.h, stackchk.h, stacks.h, stime.h,
10130 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
10131 tags.h, threads.h, throw.h, unif.h, values.h, variable.h, vectors.h,
10133 Prefixed each each exported symbol with SCM_API.
10135 * continuations.c: Added comment about the use of the extern
10136 declarations of {get,set}context() functions used in the ia64 port.
10138 * continuations.h, gc.c: `__libc_ia64_register_backing_store_base'
10139 is meant to be a `unsigned long *'.
10141 * filesys.c: Include `direct.h' if possible. Use local
10142 `win32-dirent.h' for the native M$-Windows port. Define S_IS*()
10143 macros for M$-Windows. Implementation of `fstat_Win32()' which is
10144 able to differentiate between sockets and other file descriptors.
10145 Use this function as wrapper in `scm_fstat()'. Fixed typo in
10148 * fports.c: Include `io.h' is possible. Put `*fp' into referring
10149 statement block in `scm_fport_buffer_add()'.
10150 Some corrections in `getflags()'.
10152 * gdb_interface.h (GDB_INTERFACE): Also support __CYGWIN__.
10154 * guile.c: Make sure to define __SCM_IMPORT__ for shared library
10155 build on Win32. Disable preloaded symbols on Win2 platforms.
10157 * ioext.c, ports.c: Include `io.h' is possible.
10159 * mkstemp.c: Include `process.h' is possible.
10161 * net_db.c: Disable extern declaration of `h_errno' for __CYGWIN__,
10163 Put `scm_return_entry()' into HAVE_GETSERVENT conditional.
10165 * posix.c: Remove unnecessary dirent includes and defines. Include
10166 local `win32-uname.h' for MinGW. Extern declaration of
10167 `mkstemp()' for systems where it does not exists. Make
10168 `getlogin()' available on M$-Windows.
10170 * scmsigs.c: Made `usleep()' avalable on MinGW.
10172 * stime.c: On M$-Windows `tzname[]' is known to be `_tzname[]'.
10174 * win32-dirent.c: Include "win32-dirent.h", not "dirent.h".
10176 * win32-uname.c: Include "win32-uname.h", not "uname.h".
10178 2001-10-28 Mikael Djurfeldt <mdj@linnaeus>
10180 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write):
10181 Don't apply scm_uniform_vector_length on arrays.
10183 2001-10-14 Dirk Herrmann <D.Herrmann@tu-bs.de>
10185 * eval.c (scm_lookupcar, scm_m_letstar, scm_m_do, iqq,
10186 scm_m_define, scm_m_letrec1, scm_m_let, scm_m_expand_body,
10187 scm_macroexp, unmemocopy, scm_eval_args, scm_deval_args,
10188 SCM_CEVAL, scm_map, scm_init_eval): When building lists, prefer
10189 scm_list_<n> over scm_cons[2]?.
10191 (scm_unmemocar, scm_m_cond, scm_m_letstar, scm_m_letrec1,
10192 scm_m_let, scm_m_atbind, unmemocopy, SCM_CEVAL, SCM_APPLY): Use
10193 SCM_C[AD][AD]R instead of explicit form.
10195 (scm_m_set_x, scm_m_cond, scm_m_letstar, scm_m_do): Reordered
10196 comparison parameters.
10198 (scm_m_case, scm_m_cond, scm_m_letstar, scm_m_do, SCM_CEVAL): Use
10199 !SCM_NULLP instead of SCM_NIMP.
10201 (scm_m_case): Don't copy the form. Renamed proc to clause and
10202 minimized its scope. Renamed x to clauses. Removed side
10203 effecting operation from macro call.
10205 (scm_m_cond): Don't copy the form. Renamed arg1 to clause and
10206 minimized its scope. Renamed x to clauses. Minimized the scope
10207 of variable 'len'. Make sure the else clause is treated specially
10208 even in case of '=>' occurences. Don't change the else to #t in
10209 order to be able to distinguish this case in the evaluator. Leave
10210 type checking of the recipient to the evaluator.
10212 (scm_c_improper_memq): Made the comment somewhat clearer.
10214 (scm_m_lambda): Renamed proc to formals. Removed unnecessary
10215 test for SCM_IM_LET at the place of the formal parameters.
10216 Simplified the formal parameter checking.
10218 (scm_m_letstar): Added Comment. Renamed proc to bindings.
10219 Renamed arg1 to binding and minimized its scope. Eliminated
10220 unnecessary consing.
10222 (scm_m_do): Renamed proc to bindings. Minimized the scope of
10225 (build_binding_list): New static function.
10227 (unmemocopy): Don't use SCM_TYP7 on pairs (it's unclean).
10228 Further, split up the 'letrec' unmemoizing code to the
10229 corresponding parts for 'do', 'let' and 'letrec', adding comments
10230 to each form. Cleanup the handling of the do form (This removes
10231 some *real* code :-).
10233 (SCM_CEVAL): Removed side effecting operation from macro call.
10234 Handle the 'else clause of the 'cond form specially - the symbol
10235 'else is not replaced with #t any more.
10237 2001-10-14 Gary Houston <ghouston@arglist.com>
10239 * version.c (scm_version): use sprintf instead of snprintf,
10240 for portability. thanks to Bill Schottstaedt.
10242 2001-10-14 Mikael Djurfeldt <mdj@linnaeus>
10244 * read.c (scm_lreadr): When user-defined hash procedure returns
10245 SCM_UNSPECIFIED: Fall back to standard handling instead of raising
10246 an exception. (This prevents parsing of uniform vectors from
10247 interfering with parsing of numbers.)
10249 2001-10-13 Marius Vollmer <mvo@zagadka.ping.de>
10251 * numbers.c: Set NO_PREPRO_MAGIC when defining our version of
10252 PTRDIFF_MIN. Thanks to Ken Raeburn.
10254 2001-10-07 Marius Vollmer <mvo@zagadka.ping.de>
10256 * Makefile.am (EXTRA_libguile_la_SOURCES): Added "mkstemp.c".
10258 * eval.c (scm_m_atbind): First try to find the variable without
10259 defining it locally; when it has not been found, define it
10262 * modules.c (module_variable): Pass over variables that exist but
10265 2001-10-06 Marius Vollmer <mvo@zagadka.ping.de>
10267 * backtrace.c (display_backtrace_file_and_line): Only use
10268 scm_basename when POSIX support is compiled in. Thanks to Chris
10271 2001-10-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
10273 * numbers.c (mem2uinteger): Return number read so far when coming
10274 across a hexdigit after having read a # or if not reading a hex
10275 value. This will enable the calling code to correctly handle
10276 forms like 1e2. (The background is, that the exponent markers d,
10277 e and f are also hexdigits.) Thanks to Mikael Djurfeldt for
10278 providing this patch.
10280 (mem2complex): Fix erroneous double-negation. Now, numbers like
10281 1-i will be read correctly.
10283 2001-10-12 Mikael Djurfeldt <mdj@linnaeus>
10285 * debug.c (scm_mem_to_proc): Fixed typo in previous change.
10287 * validate.h (SCM_VALIDATE_DOUBLE_DEF_COPY): New macro.
10289 2001-10-12 Dirk Herrmann <D.Herrmann@tu-bs.de>
10291 * print.c (scm_print_state_vtable, print_state_pool):
10292 Initialize. These variables are now registered as gc roots.
10294 (scm_current_pstate): Update documentation.
10296 (scm_current_pstate, scm_make_print_state, scm_free_print_state,
10297 scm_prin1, scm_init_print): print_state_pool is registered as a
10298 gc root and thus does not need to be protected by a surrounding
10301 (make_print_state): The car of print_state_pool no longer holds
10302 the scm_print_state_vtable.
10304 (scm_current_pstate, scm_make_print_state, print_circref,
10305 scm_iprin1, scm_prin1, scm_iprlist): Prefer !SCM_<foo> over
10308 (scm_prin1): When building lists, prefer scm_list_<n> over
10311 (scm_iprlist): Removed a redundant SCM_IMP test.
10313 (scm_simple_format): Use SCM_EQ_P to compare SCM values.
10315 2001-10-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
10317 * debug.c (scm_make_iloc): Prefer !SCM_<foo> over SCM_N<foo>.
10319 (scm_memcons, scm_mem_to_proc): When building lists, prefer
10320 scm_list_<n> over scm_cons[2]?.
10322 (scm_mem_to_proc): Prefer SCM_CONSP over SCM_NIMP.
10324 (scm_procedure_name): Use SCM_CADR instead of explicit form.
10326 (debugobj_print): Coerce scm_intprint arg 1 to long, not int.
10327 Thanks to Rob Browning for the patch (see log entry 2001-09-21) -
10328 for some reason his patch didn't make it into the cvs.
10330 2001-10-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
10332 * numbers.c (mem2decimal_from_point): Cleaned up the parsing a
10333 little bit - should even be somewhat more accurate now.
10335 2001-10-08 Rob Browning <rlb@defaultvalue.org>
10337 * gc.c: support ia64 register backing store.
10338 (SCM_MARK_BACKING_STORE): new macro.
10340 * continuations.h: support ia64 register backing store.
10341 (struct scm_t_contregs): add ia64 register backing store.
10343 * continuations.c: support ia64 register backing store.
10344 (continuation_mark): mark ia64 register backing store.
10345 (continuation_free): free ia64 register backing store.
10346 (scm_make_continuation): capture ia64 register backing store.
10347 (copy_stack_and_call): copy ia64 register backing store.
10349 2001-10-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
10351 * hashtab.c (scm_hash_fn_create_handle_x): The result of assoc_fn
10352 is known to be #f if no entry is found. Thus, use !SCM_FALSEP
10353 instead of SCM_NIMP to test for that case.
10355 * strings.h (SCM_SET_STRING_LENGTH): Cast the length to
10356 scm_t_bits instead of long.
10358 2001-10-06 Marius Vollmer <mvo@zagadka.ping.de>
10360 * tags.h (SCM_T_BITS_MAX, SCM_T_SIGNED_BITS_MAX,
10361 SCM_T_SIGNED_BITS_MIN): New.
10362 * numbers.h (SCM_MOST_POSITIVE_FIXNUM, SCM_MOST_NEGATIVE_FIXNUM):
10363 Use them to make these macros computable by the preprocessor.
10365 * num2integral.i.c (INTEGRAL2NUM): Let the preprocessor test
10366 whether the integral type fits in a fixnum, not the compiler.
10367 This removes a spurious compiler warning. Also, honor the
10368 NO_PREPRO_MAGIC flag to suppress any preprocessor tests. This is
10369 needed for `long long's.
10371 * numbers.c: Define NO_PREPRO_MAGOC when including
10372 num2integral.c.i for `long long' and `signed long long'.
10374 2001-10-06 Mikael Djurfeldt <mdj@linnaeus>
10376 These changes fixes a race condition in the Guile coop - pthread
10377 compatibility code.
10379 * coop.c (mother_awake_p): New variable.
10380 (coop_create): Set mother_awake_p before creating or signalling
10381 mother; wait until mother is going to sleep before returning.
10382 (mother): Reset mother_awake_p before going to sleep.
10384 2001-10-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
10386 * options.c (protected_objects, scm_init_options): The content of
10387 protected_objects is now protected from garbage collection using
10388 scm_gc_register_root instead of scm_permanent_object.
10390 (get_option_setting): New static function that computes an option
10391 setting as it was formerly done in the function scm_options.
10393 (get_documented_option_setting): New static function that
10394 returns option documentation as it was formerly done in the
10395 function scm_options. Note that documentation C strings are no
10396 longer precomputed into SCM objects. Instead, they are converted
10397 into SCM strings every time get_documented_option_setting is
10400 (change_option_setting): New static functions that modifies the
10401 option setting as it was formerly done in the function
10402 scm_options. The function is now exception safe, i. e. won't
10403 cause a memory leak when interrupted. Further, only non-immediate
10404 option values are added to the protection list.
10406 (scm_options): This function now has only the purpose to dispatch
10407 to to get_option_setting, get_documented_option_setting or
10408 change_option_setting, depending on the arguments given to
10411 (scm_init_opts): Don't convert documentation C strings into SCM
10412 strings. Further, don't protect any object values: They _must_
10413 be immediate values, otherwise there is no guarantee that they
10414 have not been collected before anyway.
10416 * options.[ch] (scm_t_option): Made type unsigned, name into a
10417 constant char* and val into a scm_t_bits type.
10419 (scm_options, scm_init_opts): The number of options is guaranteed
10420 to be larger or equal to zero. Thus, the type is changed to
10423 2001-10-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
10425 * num2integral.i.c (NUM2INTEGRAL): Eliminated some warnings about
10426 testing an unsigned value for being >= 0.
10428 2001-10-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
10430 * numbers.h: Removed old comment about using SCM_CAR to access
10433 (SCM_MOST_POSITIVE_FIXNUM, SCM_MOST_NEGATIVE_FIXNUM): Make sure
10434 the return value is signed. Thanks to Brian Crowder for the bug
10437 (SCM_SRS): Avoid unnecessary casting and don't unpack input
10438 values. With this patch, SCM_SRS can be safely used for other
10439 types than scm_t_signed_bits. However, it should still better be
10440 an internal macro and thus be renamed to SCM_I_SRS.
10442 (SCM_MAKINUM, SCM_INUM): Use proper casting.
10444 2001-10-03 Gary Houston <ghouston@arglist.com>
10446 * continuations.h, unif.h: in the descriptions of the bit patterns
10447 of the heap cells, make bit 0 the least significant.
10449 2001-09-25 Thien-Thi Nguyen <ttn@glug.org>
10451 * chars.h (SCM_MAKE_CHAR): Use `scm_t_bits' instead of `intptr_t'.
10452 Thanks to Golubev I. N.
10454 2001-09-25 Gary Houston <ghouston@arglist.com>
10456 * ports.c (scm_drain_input): extended the docstring. thanks to
10457 Alex Schroeder and Thien-Thi Nguyen.
10459 2001-09-23 Mikael Djurfeldt <mdj@linnaeus>
10461 * validate.h (SCM_NUM2FLOAT, SCM_NUM2DOUBLE,
10462 SCM_VALIDATE_FLOAT_COPY, SCM_VALIDATE_DOUBLE_COPY): New
10463 macros. (The NUM names might soon change.)
10465 * numbers.h: Added missing declarations.
10467 2001-09-22 Mikael Djurfeldt <mdj@linnaeus>
10469 * Makefile.am: Distribute num2float.i.c.
10471 * num2float.i.c: New file, multiply included by numbers.c, used
10472 to "templatize" the float <-> num conversion routines.
10474 * numbers.c: New functions: scm_num2float, scm_float2num,
10475 scm_num2double, scm_double2num.
10477 2001-09-21 Rob Browning <rlb@defaultvalue.org>
10479 * .cvsignore: really add version.h
10481 * strings.h (SCM_SET_STRING_LENGTH): coerce "l" to a long.
10482 Otherwise it fails on the alpha. However, we might rather choose
10483 this size conditionally.
10485 * numbers.c (scm_gcd): change "k" to a long from an int.
10486 Otherwise it fails on the alpha. However, we might rather choose
10487 this size conditionally.
10489 * error.c (scm_wta): coerce char* to intptr_t before int
10492 * debug.c (debugobj_print): coerce scm_intprint arg 1 to long, not
10495 * chars.h (SCM_MAKE_CHAR): coerce value to intptr_t.
10497 2001-09-20 Mikael Djurfeldt <mdj@linnaeus>
10499 * numbers.c (scm_integer_expt): Accept inexact integer in second
10500 argument. (Thanks to Bill Schottstaedt.)
10502 2001-09-20 Rob Browning <rlb@defaultvalue.org>
10504 * .cvsignore: add version.h
10506 * versiondat.h.in: removed (obsolete).
10508 * version.h.in: renamed from version.h.
10509 (SCM_GUILE_MAJOR_VERSION): new public macro.
10510 (SCM_GUILE_MINOR_VERSION): new public macro.
10511 (SCM_GUILE_MICRO_VERSION): new public macro.
10513 * version.h: renamed to version.h.in.
10516 (scm_major_version): support integer *_VERSION macros.
10517 (scm_minor_version): support integer *_VERSION macros.
10518 (scm_micro_version): support integer *_VERSION macros.
10519 (scm_version): support integer *_VERSION macros.
10521 2001-09-20 Mikael Djurfeldt <mdj@linnaeus>
10523 * error.c, error.h: Made error keys globally accessible.
10524 Applications might want to test for these or use them in a direct
10527 * num2integral.i.c (NUM2INTEGRAL): Report an error when these
10528 routines are passed an inexact. This change in behavior is
10529 motivated by concordance with R5RS: It is more common that a
10530 primitive doesn't want to accept an inexact for an exact.
10532 2001-09-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
10534 The following patch partially undoes my patch from 2001-06-30,
10535 where I added the function scm_gc_mark_cell_conservatively. The
10536 function is buggy, since it breaks guile during conservative
10537 marking if a pointer on the stack points directly into the list of
10538 free cells on the heap: With conservative cell marking this will
10539 cause the whole free list to be scanned and marked - boom!
10541 * gc.c (allocated_mark, MARK, heap_segment,
10542 scm_gc_mark_cell_conservatively, scm_init_storage), gc.h
10543 (scm_gc_mark_cell_conservatively): Remove function
10544 scm_gc_mark_cell_conservatively and update the corresponding
10545 comments and uses accordingly. Thanks to Christopher Cramer for
10546 the patch. (Minor corrections by me.)
10548 2001-09-15 Gary Houston <ghouston@arglist.com>
10550 * root.h (scm_root_state): removed the continuation_stack and
10551 continuation_stack_ptr members, which have no apparent purpose.
10552 (scm_continuation_stack, scm_continuation_stack_ptr): #defines
10555 * root.c (root_mark), init.c (restart_stack, start_stack), gc
10556 (scm_igc): remove all references to contination_stack and
10557 continuation_stack_ptr, avoiding allocation of a vector and
10558 useless processing during gc.
10560 2001-09-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
10562 * guardians.c (tconc_t, t_tconc): Renamed tconc_t to t_tconc.
10564 (TCONC_IN): Make sure that the cell word 0 is initialized last.
10566 (guardians_t, t_guardians): Renamed guardians_t to t_guardians.
10568 (GUARDIAN, GUARDIAN_DATA): Renamed GUARDIAN to GUARDIAN_DATA.
10570 (guardian_apply, scm_get_one_zombie, scm_make_guardian,
10571 mark_and_zombify): Prefer !SCM_<foo> over SCM_N<foo>.
10573 2001-09-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
10575 * guardians.c (mark_dependencies_in_tconc,
10576 whine_about_self_centered_zombies, scm_init_guardians): Register
10577 the static global variable `self_centered_zombies' via
10578 scm_gc_register_root, to make some cdr-ing unnecessary.
10580 2001-09-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
10582 * backtrace.c (display_backtrace_file,
10583 display_backtrace_file_and_line): Use SCM_EQ_P when comparing SCM
10584 values, use SCM_FALSEP when comparing SCM values against #f.
10585 Thanks to Rob Browning for the bug report.
10587 2001-09-12 Martin Baulig <martin@home-of-linux.org>
10589 * strings.[ch] (scm_str2string): New function.
10591 2001-09-06 Marius Vollmer <mvo@zagadka.ping.de>
10593 * gc.c (scm_done_free): Always subtract size from scm_mallocated
10594 when computing nm, even if it's negative.
10595 (scm_must_malloc): Abort on overflow of scm_mtrigger.
10596 (scm_must_realloc): Likewise.
10598 2001-09-01 Michael Livshin <mlivshin@bigfoot.com>
10600 * numbers.c (scm_sys_check_number_conversions): new function,
10601 defined if Guile is compiled in debugging mode. currently checks
10602 `scm_num2ulong', should check much much more.
10604 * num2integral.i.c (NUM2INTEGRAL): when converting a bignum to
10605 unsigned, ensure that it's positive. thanks to Martin Baulig!
10607 2001-08-31 Dirk Herrmann <D.Herrmann@tu-bs.de>
10609 * __scm.h: Added new section about compile time selectable
10612 (long_long, ulong_long, scm_sizet, SCM_WNA, SCM_OUTOFRANGE,
10613 SCM_NALLOC, SCM_HUP_SIGNAL, SCM_INT_SIGNAL, SCM_FPE_SIGNAL,

10615 SCM_TICK_SIGNAL, SCM_SIG_ORD, SCM_ORD_SIG, SCM_NUM_SIGS):
10618 * deprecation.c (scm_include_deprecated_features): Simplified.
10620 * eval.c (EVALCAR, unmemocopy), eval.h (SCM_XEVALCAR): Use
10621 `SCM_IMP' instead of `!SCM_CELLP´.
10623 * eval.c (unmemocopy): Eliminate redundant SCM_CELLP tests.
10624 Extract side-effecting operations from macros.
10626 (scm_init_eval): Don't initialize *top-level-lookup-closure*,
10627 scm_top_level_lookup_closure_var and scm_system_transformer.
10629 * gc.c (CELL_P): New local definition to replace SCM_CELLP.
10631 (heap_segment): Use CELL_P instead of SCM_CELLP.
10633 * init.c (start_stack): Don't initialize
10634 scm_top_level_lookup_closure_var and scm_system_transformer.

10641 (scm_post_boot_init_modules): Removed deprecated initializations.
10643 * print.c (scm_ipruk): Don't access cell contents of non cells.
10645 * strings.c (scm_string_set_x): All strings are writable.
10647 * strings.h (SCM_STRINGP): Use SCM_TYP7 to determine the string
10648 type. There is only one string type now.
10650 (SCM_STRING_COERCE_0TERMINATION_X): Deprecated.
10652 * tags.h: Remove comments about two different string types.
10654 (SCM_CELLP, SCM_NCELLP): Deprecated.
10656 * variable.c (make_variable): Remove code variant for vcells.
10658 * variable.h (SCM_VARIABLE_REF, SCM_VARIABLE_SET,
10659 SCM_VARIABLE_LOC): Remove code variant for vcells.
10661 * __scm.h, deprecation.[ch]: Renamed SCM_DEBUG_DEPRECATED to
10662 SCM_ENABLE_DEPRECATED with the logic reversed.

11230 2001-07-01 Marius Vollmer <mvo@zagadka.ping.de>
11232 * strports.c (scm_read_0str, scm_eval_0str): Call
11233 scm_c_read_string and scm_c_eval_string respectively, not
11234 themselves. Thanks to Dale P. Smith!
11236 2001-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
11238 * unif.c (scm_array_set_x): The variable args does not
11239 necessarily have to be a list. Further, got rid of a redundant
11242 2001-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
11244 * list.c (SCM_I_CONS): Make sure the cell type is initialized
11247 * gc.c (s_scm_map_free_list, scm_igc, scm_gc_sweep,
11248 init_heap_seg): Fixed signedness.
11250 (init_heap_seg): Replaced strange for-loop with a while loop.
11252 * weaks.h (WEAKSH, SCM_WEAKS_H): Rename <foo>H to SCM_<foo>_H.
11254 (SCM_WVECTP): Prefer !SCM_<pred> over SCM_N<pred>.
11256 The following patch adds conservative marking for the elements of
11257 free or allocated cells.
11259 * gc.c (allocated_mark, heap_segment): New static functions.
11261 (which_seg): Deleted, since the functionality is now provided by
11262 function heap_segment.
11264 (map_free_list): Use heap_segment instead of which_seg.
11266 (MARK): If cell debugging is disabled, mark free cells
11269 (scm_mark_locations, scm_cellp): Extracted the search for the
11270 heap segment of a SCM value into function heap_segment.
11272 (scm_init_storage): Allocated cells must be marked
11275 * gc.[ch] (scm_gc_mark_cell_conservatively): New function.
11277 The following patch changes the representation of weak vectors to
11278 double cells instead of using an extension of the vector's
11281 * gc.c (MARK): Use SCM_SET_WVECT_GC_CHAIN instead of assigning to
11282 the result of SCM_WVECT_GC_CHAIN.
11284 (scm_gc_sweep): Weak vectors don't have extra fields any more.
11286 * weaks.c (allocate_weak_vector): New static function. It does
11287 not patch any previously created vector object during the
11288 construction of a weak vector, and thus doesn't need to switch
11289 off interrupts during vector creation.
11291 (scm_make_weak_vector, scm_make_weak_key_hash_table,
11292 scm_make_weak_value_hash_table, scm_make_doubly_weak_hash_table):
11293 Use allocate_weak_vector to provide the new weak vector object.
11295 * weaks.h (SCM_WVECT_TYPE, SCM_SET_WVECT_TYPE,
11296 SCM_SET_WVECT_GC_CHAIN): New macros. The weak vector subtype is
11297 now stored in the double cell.
11299 (SCM_IS_WHVEC, SCM_IS_WHVEC_V, SCM_IS_WHVEC_B, SCM_IS_WHVEC_ANY):
11300 Use SCM_WVECT_TYPE.
11302 (SCM_WVECT_GC_CHAIN): The weak objects are now chained together
11303 using an entry of the double cell.
11305 2001-06-30 Thien-Thi Nguyen <ttn@revel.glug.org>
11307 * stamp-h.in: bye bye
11309 2001-06-30 Marius Vollmer <mvo@zagadka.ping.de>
11311 * gh_eval.c (gh_eval_str): Use scm_c_eval_string instead of
11314 * load.c, load.h (scm_c_primitive_load,
11315 scm_c_primitive_load_path): New.
11317 * strports.c, strports.h (scm_c_read_string): Renamed from
11318 scm_read_0str. Also, added "const" qualifier to argument.
11319 (scm_c_eval_string): Renamed from scm_eval_0str.

11332 SCM_LIST6, SCM_LIST7, SCM_LIST8, SCM_LIST9, scm_listify): Deprecated.
11333 (lots of files): Use the new functions.
11335 * goops.c (CALL_GF1, CALL_GF2, CALL_GF3, CALL_GF4): Use scm_call_N.
11337 * strings.c: #include "libguile/deprecation.h".
11339 2001-06-27 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
11341 * read.c (scm_lreadr): When reading a hash token, check for a
11342 user-defined hash procedure first, so that overriding the builtin
11343 hash characters is possible (this was needed for implementing
11344 SRFI-4's read synax `f32(...)').
11346 * num2integral.i.c: Use scm_t_signed_bits instead of scm_t_bits,
11347 because the latter is unsigned now and breaks comparisons like
11348 (n < (scm_t_signed_bits)MIN_VALUE).
11350 2001-06-26 Neil Jerram <neil@ossau.uklinux.net>
11352 * eval.h, eval.c (scm_call_4): New function.
11354 * eval.c (SCM_APPLY, SCM_CEVAL, ENTER_APPLY): Call trap handlers

11359 SCM_APPLY_FRAME_HDLR, SCM_EXIT_FRAME_HDLR): Add three new options
11360 for trap handler procedures.
11362 * debug.h (SCM_RESET_DEBUG_MODE): Add checks for trap handler
11363 procedures not being #f.
11365 2001-06-27 Michael Livshin <mlivshin@bigfoot.com>
11367 * Makefile.am (c-tokenize.c): add rule to generate it.
11368 (EXTRA_DIST): add c-tokenize.lex, so it gets distributed.
11370 filter-doc-snarfage.c: remove.
11372 2001-06-26 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
11374 * ports.c (scm_output_port_p): Use result of SCM_COERCE_OUTPORT.
11376 The following set of changes makes compiling Guile under various
11377 Windows compilers easier. Compilation under GNU systems should
11378 not be affected at all.
11380 Thanks to Stefan Jahn for all necessary information, patches and
11383 * posix.c: Conditialize getpwent, getgrent, kill, getppid, getuid,

11406 * guile.c (inner_main): Under Windows, initialize socket library
11407 and initialize gdb_interface data structures.
11409 * gdb_interface.h: Under Windows, gdb_interface cannot be
11410 initialized statically. Initialize at runtime instead.
11412 * fports.c (write_all): ssize_t -> size_t.
11413 (fport_print): Conditionalize call to ttyname().
11414 (getflags): New function, compiled only under Windows.
11416 * filesys.c: Conditionalize inclusion of <pwd.h>. Conditionalize
11417 primitives chown, link, fcntl.
11418 (scm_basename, scm_dirname): Under Windows, handle \ as well as /
11421 * backtrace.c: Include <io.h> under Windows.

11500 * validate.h (SCM_VALIDATE_SUBSTRING_SPEC_COPY): Eliminate
11501 warning about comparing signed and unsigned values. This fix is
11502 not optimal, since it won't work reliably if sizeof (c_start) >
11503 sizeof (size_t) or sizeof (c_end) > sizeof (size_t). A better
11504 solution is to define this macro as an inline function, thus
11505 allowing to specifiy the types of c_start and c_end.

11565 * backtrace.c (display_backtrace_body): Use SCM_VALIDATE_STACK
11566 and SCM_VALIDATE_OPOUTPORT instead of SCM_ASSERT. Fix signedness

11987 value of 2 now corresponds to the former 1, the current 1
11988 corresponds to the former situation that SCM_VOIDP_TEST was
11991 (SCM): Now defined as typedef struct scm_unused_struct * SCM;
11992 If this appears to be not ANSI compliant, we will change it to

12045 Changed use of scm_array->scm_array_t and
12046 scm_array_dim->scm_array_dim_t to enable build with
12047 --disable-deprecated.
12049 2001-05-24 Michael Livshin <mlivshin@bigfoot.com>
12051 The purpose of this set of changes is to regularize Guile's usage
12052 of ANSI C integral types, with the following ideas in mind:
12054 - SCM does not nesessarily have to be long.
12055 - long is not nesessarily enough to store pointers.
12056 - long is not nesessarily the same size as int.
12058 The changes are incomplete and possibly buggy. Please test on

13219 2001-04-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
13221 * gc.c (MARK): Re-introduce a cheap sanity test for non debug
13222 mode, as suggested by Michael Livshin.
13224 2001-03-31 Michael Livshin <mlivshin@bigfoot.com>
13226 * backtrace.c (display_backtrace_body): since the `print_state'
13227 variable is not used (instead its data field is used directly as
13228 `pstate'), protect it from the hungry compiler optimizations.
13229 thanks to Bill Schottstaedt for the report.
13231 2001-03-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
13233 * gc.[ch] (scm_tc16_allocated): New type tag for allocated cells.
13234 It is only defined and used if guile is compiled with
13235 SCM_DEBUG_CELL_ACCESSES set to true. It's purpose is, to never
13236 let cells with a free_cell type tag be visible outside of the
13237 garbage collector when in debug mode.
13239 * gc.c (scm_debug_cell_accesses_p): Set to true as default.
13241 (scm_assert_cell_valid): Use a local static variable to avoid
13244 (MARK): Only check for rogue cell pointers in debug mode. Use
13245 scm_cellp for this purpose and place all checks for rogue pointers
13246 into that function. Further, since due to conservative scanning
13247 we may encounter free cells during marking, don't use the standard
13248 cell type accessor macro to determine the cell type.
13250 (scm_cellp): Check if the cell pointer actually points into a
13253 (scm_init_gc): Initalize scm_tc16_allocated.
13255 * gc.h (GCH): Renamed to SCM_GC_H.
13257 (SCM_VALIDATE_CELL): Enclose the expression in brackets. This
13258 might be unnecessary, but I feel better this way :-)
13260 (SCM_GC_CELL_TYPE): New macro.
13262 (SCM_SETAND_CDR, SCM_SETOR_CDR): Deprecated. These are not used
13263 in guile, and it is unlikely that they will be applied to real
13266 (SCM_SET_FREE_CELL_TYPE): Removed. It was not used.
13268 (SCM_GC_SET_ALLOCATED): New macro. Only non-empty if guile is
13269 compiled with SCM_DEBUG_CELL_ACCESSES set to true.
13271 (SCM_NEWCELL, SCM_NEWCELL2): Use of SCM_GC_SET_ALLOCATED will
13272 make sure that in debug mode no free cell will ever be visible
13273 outside of the garbage collector.
13275 2001-03-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
13277 * async.c (scm_asyncs_pending): Don't use != to compare SCM

13284 Remove suspicious use of SCM_SLOPPY_CONSP.
13286 * eq.c (scm_equal_p), tags.h (SCM_ECONSP): Use SCM_CONSP instead
13287 of SCM_SLOPPY_CONSP. A sane compiler should be able to perform
13288 the corresponding optimization.
13290 * eval.c (iqq): Use proper type check.
13292 (scm_m_expand_body): Remove redundant type checks.
13294 (promise_print): Don't access promise cells as pairs.
13296 * eval.c (EVALCAR, iqq, scm_m_expand_body, scm_eval_args,
13297 scm_deval_args SCM_CEVAL), guardians.c (scm_guard), hashtab.c
13298 (scm_internal_hash_fold), print.c (scm_iprlist): Use !SCM_CELLP
13299 for SCM_NCELLP, !SCM_CONSP for SCM_NCONSP, !SCM_IMP for SCM_NIMP,
13300 !SCM_FALSEP for SCM_NFALSEP, !SCM_NULLP for SCM_NNULLP
13302 * eval.c (scm_m_define, scm_macroexp, SCM_CEVAL), print.c
13303 (scm_iprin1): Use new macro predicate and accessors.

13308 * eval.h (EVALH), macros.h (MACROSH), ports.h (PORTSH), procs.h
13309 (PROCSH), tags.h (TAGSH), variable.h (VARIABLEH): Renamed to
13310 SCM_EVAL_H, SCM_MACROS_H, SCM_PORTS_H, SCM_PROCS_H, SCM_TAGS_H and
13311 SCM_VARIABLE_H. Even the macros that are used to inhibit
13312 including a header file twice should be in the SCM_ namespace.
13314 * fluids.c (scm_swap_fluids, scm_swap_fluids_reverse),
13315 properties.c (scm_primitive_property_ref,
13316 scm_primitive_property_del_x): Prefer stronger predicates like
13317 SCM_NULLP or SCM_FALSEP over SCM_IMP.
13319 * gc.c (MARK): Use proper macros to access procedure-with-setter
13320 cell elements and closure cell elements.
13322 (gc_sweep_freelist_finish, scm_gc_sweep, init_heap_seg): Don't
13323 access free cells as pairs.
13325 (scm_unprotect_object): scm_hashq_get_handle returns #f if
13326 no hashtab entry is found.
13328 * gc.c (scm_gc_sweep), ports.c (scm_close_port): Use new macro
13329 SCM_CLR_PORT_OPEN_FLAG.
13331 * guardians.c (TCONC_IN), print.c (scm_free_print_state): Don't
13332 use SCM_SET_C[AD]R for uninitialized cells.
13334 * hashtab.c (scm_hash_fn_get_handle): Use SCM_VALIDATE_VECTOR.
13335 If the hashtable has no slots, return #f instead of '(). This
13336 unifies the return value with most assoc-functions.
13338 (scm_hash_fn_ref): Use proper type check.
13340 (scm_hashq_get_handle, scm_hashv_get_handle, scm_hash_get_handle):
13341 Removed references to non-existing functions from documentation.
13343 * keywords.c (scm_keyword_dash_symbol): Use proper macros to
13344 access keyword cell elements.
13346 * macros.h (SCM_MACROP, SCM_MACRO_TYPE, SCM_MACRO_CODE): New
13349 * ports.h (SCM_CLR_PORT_OPEN_FLAG): New macro.

13357 * smob.c (scm_markcdr): Don't access smob cells as pairs.
13359 * tags.h (SCM_SLOPPY_CONSP, SCM_SLOPPY_NCONSP): Deprecated.

13364 * variable.c (variable_print, variable_equalp, scm_variable_ref,
13365 scm_variable_set_x): Use proper macros to access variable cell
13368 (scm_variable_bound_p): Don't use SCM_NEGATE_BOOL.
13370 * variable.h (SCM_VARVCELL): Don't access variable cells as
13373 * vectors.c (scm_vector), weaks.c (scm_weak_vector): Simplified,
13374 added FIXME comment, removed register specifier.
13376 2001-03-29 Keisuke Nishida <kxn30@po.cwru.edu>
13378 * goops.c, goops.h (scm_init_oop_goops_goopscore_module): Deprecated.

13390 (scm_string_capitalize): Rewrote and corrected docstrings.

13402 * tags.h (SCM_IM_CALL_WITH_VALUES): New isym.
13403 * eval.c: Include "libguile/values.h"

13406 (unmemocopy, scm_ceval, scm_deval): Handle new isym.
13407 * eval.h (scm_sym_at_call_with_values, scm_m_at_call_with_values):
13408 New delcarations to support above change.
13410 * eval.c (scm_primitive_eval_x, scm_primitive_eval): Fix syntax
13411 errors with last change.
13413 2001-03-25 Marius Vollmer <mvo@zagadka.ping.de>

13489 scm_enclose_array, scm_array_in_bounds_p, scm_array_set_x):
13490 Validate the rest argument (note: this is only done when guile is
13491 built with SCM_DEBUG_REST_ARGUMENT=1)

13494 Replace calls to scm_wrong_num_args by SCM_WRONG_NUM_ARGS.

13502 instead of scm_wrong_num_args.

13582 * gh.h/gh_data.c (gh_ints2scm): Changed the signature to use a
13583 const int* to reflect that the input array of integers remains
13584 unchanged. Thanks to Brett Viren for the hint.
13586 2001-03-14 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
13588 * gh_data.c (gh_scm2chars, gh_scm2shorts, gh_scm2longs),

13591 (gh_scm2newstr, gh_symbol2newstr): Change call to

13614 SCM_VALIDATE_* macro or an explicit test.
13616 (scm_make_foreign_object): Don't use SCM_ASSERT to check for
13619 * macros.h (SCM_ASSYNT): On assertion failure, issue a misc-error
13620 instead of calling scm_wta.
13622 2001-03-12 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
13624 * load.c (scm_primitive_load, scm_primitive_load_path),

13643 * _scm.h: Removed #include <errno.h>.
13645 * error.c, net_db.c, putenv.c, stime.c: Removed declaration of
13646 errno variable (can be a macro on some systems, for example when
13647 using linux libc with threads).
13649 * error.c, filesys.c, gc.c, ioext.c, iselect.c, net_db.c, ports.c,
13650 posix.c, print.c, putenv.c, scmsigs.c, script.c, simpos.c, smob.c,
13651 socket.c, srcprop.c, stime.c, strop.c, unif.c, vports.c: Added
13652 #include <errno.h> in these 20 out of 100 files.
13654 2001-03-10 Gary Houston <ghouston@arglist.com>
13656 * socket.c: add a definition of SUN_LEN (from glibc) for when it's
13657 not already defined.
13659 2001-03-09 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
13661 * coop.c: Inserted #include <stdio.h>.

13697 (scm_sethostname, scm_gethostname): New prototypes.
13699 * posix.c: Added inclusion of <crypt.h>, <sys/resource.h> and
13700 <sys/file.h>, if present.
13701 (scm_init_posix): [PRIO_PROCESS, PRIO_PGRP, PRIO_USER, LOCK_SH,
13702 LOCK_EX, LOCK_UN, LOCK_NB]: New variables.

13705 (scm_sethostname, scm_gethostname): New procedures.
13707 2001-03-08 Neil Jerram <neil@ossau.uklinux.net>
13709 * ports.c (scm_port_column): Docstring fixes: (i) port-line arg is
13710 not optional (ii) "recommend" spelling correction.
13712 2001-03-08 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
13714 * ramap.c (racp): Removed optimization which caused array copying
13715 to fail if the two arrays shared storage. Re-inserted the IVDEP
13716 macros removed in the change of 2000-03-09. (Don't really have a
13717 complete grasp of what they are for, but they seem to be necessary
13718 on Crays. This needs testing!) Thanks to Miroslav Silovic.
13720 * hash.c (scm_string_hash): Don't downcase characters.
13722 2001-03-07 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
13724 * symbols.c (scm_symbols_prehistory): Changed symbol hash table
13725 size from 277 --> 1009.
13727 * symbols.c, symbols.h (scm_sys_symbols): New function GUILE_DEBUG
13730 * coop-threads.c: Fixed change of 2001-03-06.
13732 * validate.h: Code formatting.
13734 2001-03-07 Keisuke Nishida <kxn30@po.cwru.edu>
13736 * Makefile.am (*.x): Add dependency on snarf.h and guile-doc-snarf.in.
13737 (*.doc): Add dependency on guile-snarf.awk.in.
13739 * guile-snarf.awk.in: Neglect spaces at the end of
13740 SCM_SNARF_DOCSTRING_END. Skip lines "# NN ..." in the
13741 middle of docstrings. (To avoid the problem with gcc-2.96.)

13745 * coop-threads.c (scm_call_with_new_thread), load.c

13749 (potentially) issue a scm-misc-error or wrong-num-args error
13752 * load.c (scm_search_path): Use SCM_ASSERT_TYPE to give details
13753 about the expected type with the wrong-type-arg error message.
13755 * smob.c (scm_make_smob): Abort on misuse of smob - it indicates
13756 a C level bug that can't be fixed from scheme anyway.
13758 2001-03-05 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
13760 * eval.c (scm_m_letstar): Removed check for duplicate bindings.
13761 Duplicate bindings are OK in a let* since a let* is semantically
13762 equivalent to a nested set of let:s.
13764 2001-03-05 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
13766 * print.c (scm_print_options): Fixed texinfo in docstring.
13768 * net_db.c (scm_getserv, scm_getproto, scm_getnet): Return #f if
13769 the underlying functions getservent, getprotoent or getnetent
13770 return NULL instead of signalling an error.
13772 2001-03-04 Gary Houston <ghouston@arglist.com>
13774 * socket.c (scm_fill_sockaddr): don't allow buffer overflows when
13775 taking an unexpectedly large filename for an AF_UNIX socket from
13776 bind/connect/sendto (thanks to Martin Grabmueller).
13778 * socket.c (scm_sock_fd_to_port, SCM_SOCK_FD_TO_PORT): removed the
13779 former and adjusted the latter.
13780 (scm_socket, scm_socketpair): cosmetic changes.
13781 (scm_getsockopt, scm_setsockopt): declare optlen as int, not
13782 size_t as socklen_t substitute. don't restrict args/return values
13783 to INUM: allow full range of int or size_t.
13784 (scm_fill_sockaddr): check arguments before allocating memory, to
13785 avoid leakage. use malloc, not scm_must_malloc.
13786 (scm_connect, scm_bind, scm_sendto): use int, not size_t as socklen_t
13787 substitute. free the sockaddr structure before throwing an error.
13788 (scm_init_add_buffer): procedure removed, together with its static
13789 buffer scm_addr_buffer, which wouldn't be thread safe. instead,
13790 define a macro MAX_ADDR_SIZE and declare the buffer where needed.
13791 (scm_accept, scm_getpeername, scm_getsockname, scm_recvfrom,
13792 scm_sendto): use a local buffer instead of scm_addr_buffer.
13793 adjust for new SCM_SOCK_FD_TO_PORT. use int for address size,
13795 (scm_recvfrom): set addr->sa_family to AF_UNSPEC before the recvfrom
13796 call to detect whether recvfrom could be bothered to set the address.
13797 (scm_init_socket): don't call scm_init_addr_buffer.
13799 2001-03-04 Dirk Herrmann <D.Herrmann@tu-bs.de>

13810 scm_array_to_list, scm_array_prototype), validate.h
13811 (SCM_VALIDATE_NUMBER_COPY): Don't call function scm_wta, call
13812 scm_misc_error or scm_wrong_type_arg instead.
13814 * validate.h (SCM_WTA, RETURN_SCM_WTA): Deprecated.
13816 2001-03-04 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
13818 * goops.c, goops.h (scm_sys_pre_expand_closure_x): Removed.

13829 scm_lreadparen, scm_lreadrecparen), script.c (script_get_octal,

13831 call function scm_wta, call scm_misc_error or scm_wrong_type_arg

13846 immediate, literal constant should be evaluated.
13847 * eval.c (scm_s_duplicate_formals): New error message string.
13848 (scm_c_improper_memq): New function.
13849 (scm_m_lambda): Check for duplicate arguments.
13850 (scm_ceval, scm_deval): When executing a body: only cons a new
13851 toplevel environment frame when it is different from the
13852 existing one; use EVALCAR instead of SIDEVAL so that we can properly
13853 check for empty combinations; use SCM_EVALIM2 for the same reason
13854 in the non-toplevel loop.
13855 (nontoplevel_cdrxnoap, nontoplevel_cdrxbegin, nontoplevel_begin):
13856 New labels with the meaning of their non-"nontoplevel" partners,
13857 but they are used when it is known that the body is not evaluated at
13859 (scm_apply, scm_dapply): use SCM_EVALIM2 to get proper error
13860 reporting for empty combinations.
13862 2001-03-02 Keisuke Nishida <kxn30@po.cwru.edu>

13886 (scm_symbol_to_string, scm_string_to_symbol): Changed use of @t{}

13928 scm_make_polar): Rename arguments `z1' and `z2' to `x' and `y',
13929 since use of `z' suggests that the arguments may be complex.

13947 (make_class_from_template): Do not bother to set the current
13948 module around the call to DEFVAR, scm_eval takes care of that.
13949 (scm_init_goops): Make scm_module_goops and
13950 scm_goops_lookup_closure permanent objects.
13952 * eval.c (scm_ceval, scm_deval): When evaluating expressions on
13953 top level, create a fresh top-level environment for each
13954 expression instead of mutating the exisint frame. This is
13955 important when that frame is closed over.
13957 * numbers.c (s_scm_logior) [SCM_DIGSTOOBIG]: Also use
13958 SCM_DIGSPERLONG instead of DIGSPERLONG.
13960 2001-02-21 Marius Vollmer <mvo@zagadka.ping.de>
13962 * eval.c (scm_ceval, scm_deval): Check for wrong number of args
13963 before applying arrow procedure in `cond' and before applying
13964 receiver procedure in call-with-current-continuation.
13965 (scm_i_eval): Do not invoke scm_copy_tree in argument in SCM_XEVAL
13966 macro. The argument is expanded more than one time.
13968 * numbers.c (scm_logior) [SCM_DIGSTOOBIG]: Correctly use
13969 SCM_BIGDIG instead of BIGDIG. Thanks to Steven G. Johnson!
13971 2001-02-20 Marius Vollmer <mvo@zagadka.ping.de>
13973 * guile-doc-snarf.in, guile-func-name-check.in: Added copyright

14093 2001-02-13 Marius Vollmer <marius.vollmer@uni-dortmund.de>
14095 * gc_os_dep.c: Do not include <linux/version.h>. It makes no
14096 sense to compile for a specific kernel version. Do not include
14097 <asm/signal.h> while defining __KERNEL__. This hack should no
14098 longer be needed and caused problems.
14100 2001-02-13 Marius Vollmer <mvo@zagadka.ping.de>
14102 * eval.c (scm_ceval, scm_deval): use `SIDEVAL' instead of

14120 (scm_i_eval, scm_i_eval_x, scm_eval, scm_eval_x): Changed argument
14121 names to better reflect their meaning.
14123 * eval.c (scm_ceval, scm_deval): Recognize when `begin' is being
14124 evaluated at top-level and synronize lookup closure before
14125 executing every subform.
14126 (scm_primitve_eval_x, scm_primitive_eval): New functions.
14127 (scm_eval_x, scm_eval): Reimplement in terms of
14128 scm_primitive_eval_x and scm_primitive_eval, respectively.
14130 2001-02-09 Marius Vollmer <mvo@zagadka.ping.de>
14132 * macros.c (scm_macro_name, scm_macro_transformer): Use

14150 2001-02-08 Marius Vollmer <marius.vollmer@uni-dortmund.de>
14152 * modules.h (scm_selected_module, scm_current_module): Renamed
14153 scm_selected_module to scm_current_module to synchronize Scheme
14155 (scm_select_module, scm_set_current_module): Likewise. Changed
14158 * ports.c (scm_port_for_each): Make a snapshot of the port table
14159 before iterating over it. The table might change while the user
14160 code is running. With the snapshot, the user can depend on the
14161 fact that each port that existed at the start of the iteration is
14162 encountered exactly once. (ice-9 popen) depends on this.
14164 2001-02-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
14166 * strings.h (SCM_STRING_MAX_LENGTH): New macro.
14168 * strings.c (scm_makstr, scm_take_str, scm_make_string): Added
14169 range checking for the size parameter. Thanks to Martin
14170 Grabmueller for the hint.

14179 * vectors.h (SCM_VECTOR_MAX_LENGTH): New macro.
14181 * vectors.c (scm_make_vector, scm_c_make_vector): Improved the
14182 checking of the size parameter for type correctness and valid
14183 range. Thanks to Rob Browning for reporting the problem. Instead
14184 of deferring interrupts, scm_remember_upto_here_1 is used.
14186 2001-02-05 Keisuke Nishida <kxn30@po.cwru.edu>
14188 * dump.c (scm_store_cell_object, scm_restore_cell_object): Removed.

14212 2001-02-03 Michael Livshin <mlivshin@bigfoot.com>
14214 * gc.c (DOUBLECELL_ALIGNED_P): new macro, a better-named analog of
14215 the deprecated SCM_DOUBLE_CELLP.
14217 * tags.h (SCM_DOUBLE_CELLP): deprecated.
14219 2001-02-02 Keisuke Nishida <kxn30@po.cwru.edu>
14221 * dump.c, dump.h: New files.

14368 This patch was sent by Martin Grabmueller and makes sure that
14369 parameter errors are reported correctly by the lexicographic
14370 ordering predicates.
14372 * strorder.c (string_less_p, string_ci_less_p): New functions.
14374 (scm_string_less_p, scm_string_ci_less_p): Extracted the core
14375 functionality into string_less_p, string_ci_less_p respectively.
14376 The remaining code is just a wrapper to do the parameter
14379 (scm_string_leq_p, scm_string_gr_p, scm_string_geq_p): Check the
14380 parameters and call string_less_p instead of scm_string_less_p.
14382 (scm_string_ci_leq_p, scm_string_ci_gr_p, scm_string_ci_geq_p):
14383 Check the parameters and call string_less_ci_p instead of

14459 2001-01-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
14461 * __scm.h (SCM_FIXNUM_BIT): Added. The name is chosen in analogy
14462 to the names in limits.h.
14464 * numbers.c (abs_most_negative_fixnum): Added.

14488 from Matthias Köppe:
14490 * objects.h (SCM_SET_ENTITY_SETTER): new macro. SCM_ENTITY_SETTER
14491 casts its result, so doesn't yield an lvalue per ANSI C.

14494 SCM_SET_ENTITY_SETTER.
14495 (clear_method_cache): use SCM_SET_ENTITY_PROCEDURE.
14497 * gc.h (SCM_GC_SET_CARD_BVEC): new macro. SCM_GC_CARD_BVEC casts
14498 its result, so doesn't yield an lvalue per ANSI C.

14500 (SCM_GC_CLR_CARD_FLAGS): redefined in terms of
14501 SCM_GC_SET_CARD_FLAGS.
14502 (SCM_GC_SET_CARD_FLAG, SCM_GC_CLR_CARD_FLAGS): ditto.
14504 * gc.c (INIT_CARD): use the explicit setter macro to set the bvec.
14506 2001-01-08 Gary Houston <ghouston@arglist.com>
14508 * validate.h (SCM_VALIDATE_SUBSTRING_SPEC_COPY): new macro.
14509 * ioext.c (scm_read_string_x_partial, scm_read_delimited_x),
14510 socket.c (scm_recvfrom): use the new macro, plus minor docstring
14512 * ioext.c (scm_read_string_x_partial): don't crash if -1 is supplied
14513 for fdes. if current input port is used, check that it's a file
14516 2001-01-06 Gary Houston <ghouston@arglist.com>
14518 * ioext.c (scm_read_string_x_partial): new procedure, implements
14519 read-string!/partial.
14520 * ports.c (scm_take_from_input_buffers): new procedure used by
14521 scm_read_string_x_partial.
14522 (scm_drain_input): use scm_take_from_input_buffers.

14531 SET_GREEDY, LISTED_P, SET_LISTED, CLR_LISTED, DESTROYED_P,
14532 SET_DESTROYED): new defines/macros.
14533 (GUARDIAN_LIVE, GUARDIAN_ZOMBIES, GUARDIAN_NEXT): deleted.
14534 (add_to_live_list): takes a `guardian_t *' now, not SCM.
14535 (guardian_print): print more info.
14536 (guardian_apply): check if the guardian is destroyed, and throw an
14537 error if so. take one more optional argument `throw_p'.
14538 (scm_guard): depending on the value of `throw_p', return a boolean
14540 (scm_get_one_zombie): remove redundant property test.
14541 (guardian_t): represent the various (currently 3, I hope nothing
14542 more gets added) boolean fields as bit flags.
14543 (scm_guardian_destroyed_p, scm_guardian_greedy_p): new predicates.
14544 (scm_destroy_guardian_x): new procedure.
14546 * guardians.h: added prototypes for `scm_guardian_greedy_p' and
14547 `scm_guardian_destroyed_p'. changed prototype for `scm_guard'.

14551 * fports.c (fport_write): bugfix: handle short writes for
14552 unbuffered ports too. optimize the buffered case by minimizing
14553 the number of write/flush calls.
14554 (write_all): new helper procedure.
