1 2007-10-27 Ludovic Courtès <ludo@gnu.org>
3 * fports.c (scm_i_evict_port): Expect a port, rather than a pair
4 containing the port. Fixes a bug in the new port table (2007-08-26).
5 (scm_evict_ports): Use `scm_c_port_for_each ()'.
7 2007-10-21 Neil Jerram <neil@ossau.uklinux.net>
9 * eval.c (unmemoize_delay): Extend the environment before
10 unmemoizing the promise thunk. This fixes a segmentation fault
11 reported by Frank Schwidom.
13 2007-10-20 Julian Graham <joolean@gmail.com>
15 Add support for thread cancellation and user-defined thread
16 cleanup handlers. Small rework by Ludovic Courtès.
18 * null-threads.h (scm_i_pthread_cancel,
19 scm_i_pthread_cleanup_push, scm_i_pthread_cleanup_pop): New.
20 * pthread-threads.h (scm_i_pthread_cancel,
21 scm_i_pthread_cleanup_push, scm_i_pthread_cleanup_pop): New.
22 * scmsigs.c (scm_i_signal_delivery_thread,
23 signal_delivery_thread_mutex): New.
24 (signal_delivery_thread): Leave when `read_without_guile ()'
26 (start_signal_delivery_thread): Acquire SIGNAL_DELIVERY_THREAD
27 before spawning the thread. Initialize
28 SCM_I_SIGNAL_DELIVERY_THREAD.
29 (ensure_signal_delivery_thread): Renamed to...
30 (scm_i_ensure_signal_delivery_thread): this.
31 (scm_i_close_signal_pipe): New.
33 * threads.c (thread_mark): Mark `t->cleanup_handler'.
34 (guilify_self_1): Initialize `t->cleanup_handler' and
36 (do_thread_exit): Invoke `t->cleanup_handler'.
37 (on_thread_exit): Call `scm_i_ensure_signal_delivery_thread ()'.
38 Call `scm_i_close_signal_pipe ()' when the next-to-last thread
40 (scm_leave_guile_cleanup): New.
41 (scm_i_with_guile_and_parent): Use `scm_i_pthread_cleanup_push ()'
42 and `scm_leave_guile_cleanup ()' to leave guile mode, rather
43 than call `scm_leave_guile ()' after FUNC.
44 (scm_cancel_thread, scm_set_thread_cleanup_x,
45 scm_threads_cleanup): New.
46 (scm_all_threads): Remove SCM_I_SIGNAL_DELIVERY_THREAD from the
48 * threads.h (scm_i_thread)[cleanup_handler, canceled]: New
50 Add declarations of new functions.
52 2007-10-17 Ludovic Courtès <ludo@gnu.org>
54 * read.c (CHAR_IS_BLANK_): Add `\r' (ASCII 0x0d). This fixes a
55 regression compared to 1.8.2. Reported by Puneet
58 2007-10-10 Ludovic Courtès <ludo@gnu.org>
60 * pthread-threads.h (SCM_I_PTHREAD_MUTEX_INITIALIZER): Check
61 `SCM_NEED_BRACES_ON_PTHREAD_MUTEX_INITIALIZER'.
63 (SCM_I_GSC_NEED_BRACES_ON_PTHREAD_MUTEX_INITIALIZER): New.
64 * gen-scmconfig.c (main): Define
65 `SCM_NEED_BRACES_ON_PTHREAD_MUTEX_INITIALIZER'.
67 2007-10-04 Ludovic Courtès <ludo@gnu.org>
69 * i18n.c (scm_make_locale)[!USE_GNU_LOCALE_API]: Don't call
70 `leave_locale_section ()' on failure of
71 `enter_locale_section ()' since the mutex is not held and locale
72 settings are unchanged.
73 (scm_nl_langinfo)[!USE_GNU_LOCALE_API]: Use
74 `restore_locale_settings ()' instead of `leave_locale_section ()'
75 since the mutex is not held.
77 2007-10-02 Ludovic Courtès <ludo@gnu.org>
79 * threads.c (on_thread_exit): Don't call `scm_leave_guile ()'
80 since we're already in non-guile mode. Reported by Greg Toxel
83 2007-10-01 Ludovic Courtès <ludo@gnu.org>
85 * ports.c (flush_output_port): Expect directly a port instead of
86 a pair. Fixes a bug in the new port table (2007-08-26).
88 2007-09-11 Kevin Ryde <user42@zip.com.au>
90 * posix.c (scm_putenv): Confine the putenv("NAME=") bit to mingw, use
91 putenv("NAME") as the fallback everywhere else. In particular this is
92 needed for solaris 9. Reported by Frank Storbeck.
94 2007-09-03 Ludovic Courtès <ludo@gnu.org>
96 * read.c (flush_ws): Handle SCSH block comments.
98 2007-09-03 Ludovic Courtès <ludo@gnu.org>
100 Fix alignment issues which showed up at least on SPARC.
102 * socket.c (scm_t_max_sockaddr, scm_t_getsockopt_result): New.
103 (scm_inet_pton): Change DST to `scm_t_uint32' for correct
105 (scm_getsockopt): Change OPTVAL to `scm_t_getsockopt_result' for
107 (_scm_from_sockaddr): Change ADDRESS to `scm_t_max_sockaddr *'.
108 (scm_from_sockaddr): Cast ADDRESS to `scm_t_max_sockaddr *'.
109 (MAX_SIZE_UN, MAX_SIZE_IN6): Removed.
110 (scm_accept, scm_getsockname, scm_getpeername, scm_recvfrom):
111 Use `scm_t_max_sockaddr' instead of "char max_addr[MAX_ADDR_SIZE]".
113 2007-09-03 Kevin Ryde <user42@zip.com.au>
115 * numbers.c (scm_log): Test HAVE_CLOG as well as HAVE_COMPLEX_DOUBLE
116 before using clog(). It's possible for gcc to provide the "complex
117 double" type, but for the system not to have the complex funcs.
118 (scm_exp): Ditto HAVE_CEXP for cexp().
119 (clog, cexp, carg): Remove fallback definitions. These only
120 duplicated the code within scm_log and scm_exp, and the latter have to
121 exist for the case when there's no "complex double". So better just
122 fix up the conditionals selecting between the complex funcs and plain
123 doubles than worry about fallbacks.
125 2007-09-02 Ludovic Courtès <ludo@gnu.org>
127 * socket.c (scm_make_socket_address): Free C_ADDRESS after use.
128 This fixes a memory leak.
130 2007-08-26 Han-Wen Nienhuys <hanwen@lilypond.org>
132 * fports.c gc-card.c gc.c gc.h ioext.c ports.c ports.h weaks.h
133 gc.c: replace port table with weak hash table. This simplifies
134 memory management, and fixes freed cells appearing in
135 port-for-each output.
137 * init.c (cleanup_for_exit): abort cleanup if init_mutex is still
140 2007-08-23 Ludovic Courtès <ludo@gnu.org>
142 * read.c (scm_read_quote): Record position and copy source
143 expression when asked to. Reported by Kevin.
145 * stime.c: Define `_REENTRANT' only if not already defined.
147 2007-08-21 Kevin Ryde <user42@zip.com.au>
149 * gc-card.c (scm_i_card_statistics): Record scm_tc7_number types as
150 tc16 values so big, real, complex and fraction can be distinguished.
152 (scm_i_tag_name): Return "number" for scm_tc7_number, not NULL. NULL
153 was making numbers come out as "type 23" in gc-live-object-stats.
154 Fix tests of the tc16 number types, they were checked under
155 scm_tc7_number, but the values went down the tag>=255 smob case.
156 Put smob case under scm_tc7_smob instead of using tag>=255, per
157 recommendation in comments with scm_tc7_smob to use symbolic values.
158 Use SCM_TC2SMOBNUM to extract scm_smobs index, instead of explicit
159 code. Lose some unnecessary "break" statements.
161 (scm_i_card_statistics): Use scm_hashq_create_handle_x and modify the
162 element returned, rather than two lookups scm_hashq_ref and
165 2007-08-17 Kevin Ryde <user42@zip.com.au>
167 * stime.c: Add #define _REENTRANT, to get gmtime_r() prototype on
168 solaris 2.6. Reported by anirkko.
170 2007-07-29 Ludovic Courtès <ludo@gnu.org>
172 * Makefile.am (INCLUDES): Added Gnulib includes.
173 (gnulib_library): New.
174 (libguile_i18n_v_@LIBGUILE_I18N_MAJOR@_la_LIBADD): Added
176 (libguile_la_LIBADD): Likewise.
178 * posix.c: Don't define `_GNU_SOURCE' since `gl_EARLY' arranges
179 to define it when available.
180 * srfi-14.c: Likewise.
181 * i18n.c: Likewise. Include Gnulib's <alloca.h>
182 * eval.c: Include Gnulib's <alloca.h>.
183 * filesys.c: Likewise.
184 * read.c: Don't include <strings.h> and don't provide an
185 `strncasecmp ()' replacement; use Gnulib's <string.h> and
186 `strncasecmp ()' instead.
188 2007-07-25 Ludovic Courtès <ludo@gnu.org>
190 * eval.c (macroexp): When `scm_ilength (res) <= 0', return
191 immediately. This used to produce a circular memoized
192 expression, e.g., for `(set (quote x) #t)'.
194 2007-07-22 Ludovic Courtès <ludo@gnu.org>
196 Overhauled the reader, making it faster.
198 * gdbint.c (tok_buf, tok_buf_mark_p): Removed.
199 (gdb_read): Don't use a token buffer. Use `scm_read ()' instead
202 * read.c: Overhauled. No longer use a token buffer. Use a
203 on-stack C buffer in the common case and use Scheme strings when
204 larger buffers are needed.
205 * read.h (scm_grow_tok_buf, scm_flush_ws, scm_casei_streq,
206 scm_lreadr, scm_lreadrecparen): Removed.
207 (scm_i_input_error): Marked as `SCM_NORETURN'.
209 2007-07-15 Ludovic Courtès <ludo@gnu.org>
211 * script.c (scm_compile_shell_switches): Updated copyright year.
213 2007-07-11 Ludovic Courtès <ludo@gnu.org>
215 * goops.c (scm_sys_method_more_specific_p): Added docstring.
216 Make sure LEN is greater than or equal to the minimum length of
217 specializers of M1 and M2. This fixes a segfault later on in
218 `more_specificp ()' if TARGS is too small. Reported by Marco
219 Maggi <marco.maggi-ipsu@poste.it>.
221 2007-06-26 Ludovic Courtès <ludo@gnu.org>
223 * fluids.c (next_fluid_num): When growing ALLOCATED_FLUIDS, make
224 sure to free the previous array after the new one has been
225 installed. This leak is made visible by running
226 "(define l (map (lambda (i) (make-fluid)) (iota 255)))"
227 from the REPL within Valgrind.
229 2007-06-12 Ludovic Courtès <ludo@chbouib.org>
231 * socket.c (scm_inet_ntop): In the `AF_INET' case, declare `addr4'
232 as an `scm_t_uint32' rather than re-using `addr6'. This fixes a
233 bus error on SPARC (and possibly others) due to unaligned access.
235 2007-06-07 Ludovic Courtès <ludovic.courtes@laas.fr>
237 * posix.c (scm_ttyname): Check whether RESULT is NULL before
238 making a string from it (reported by Dan McMahill). Don't call
239 `scm_from_locale_string ()' before the mutex is released.
241 2007-05-26 Ludovic Courtès <ludo@chbouib.org>
243 * eval.c (scm_m_define): Updated comment. Changed order for value
244 evaluation and `scm_sym2var ()' call, which is perfectly valid per
245 R5RS. This reverts the change dated 2004-04-22 by Dirk Herrmann.
247 2007-05-05 Ludovic Courtès <ludo@chbouib.org>
249 Implemented lazy duplicate binding handling.
251 * modules.c (scm_export): Renamed to...
252 (scm_module_export): This. Now public.
253 (module_variable): Removed.
254 (default_duplicate_binding_procedures_var): New variable.
255 (default_duplicate_binding_handlers, resolve_duplicate_binding,
256 module_imported_variable, scm_module_local_variable,
257 scm_module_variable): New functions.
258 (scm_module_import_interface): Rewritten.
259 (scm_module_reverse_lookup): Exported as a Scheme function.
260 * modules.h (scm_module_index_duplicate_handlers,
261 scm_module_index_import_obarray): New macros.
262 (scm_module_variable, scm_module_local_variable,
263 scm_module_export): New declarations.
265 2007-04-17 Ludovic Courtès <ludovic.courtes@laas.fr>
267 * numbers.c: Commented out trailing `HAVE_COMPLEX_DOUBLE' after
268 `#endif'. Use `#ifndef HAVE_XXX' rather than `#if !HAVE_XXX'.
270 2007-04-09 Han-Wen Nienhuys <hanwen@lilypond.org>
272 * numbers.c (carg): provide carg, cexp, clog in case they are
275 2007-03-12 Ludovic Courtès <ludovic.courtes@laas.fr>
277 * i18n.c (scm_nl_langinfo): `#ifdef'd uses of `GROUPING',
278 `FRAC_DIGITS', etc., which are GNU extensions. Reported by
281 2007-03-08 Kevin Ryde <user42@zip.com.au>
283 * struct.c, struct.h (scm_make_vtable): New function, providing
285 * stacks.c (scm_init_stacks): Use it.
287 2007-03-06 Kevin Ryde <user42@zip.com.au>
289 * struct.c (scm_make_struct): Check for R,W,O at end of layout when
290 allocating a tail array. If there's no such then those tail fields
291 are uninitialized and garbage SCMs there can cause a segv if printed
292 (after fetching with struct-ref).
294 2007-02-22 Kevin Ryde <user42@zip.com.au>
296 * scmsigs.c (scm_sleep): In docstring, cross refence usleep.
297 (scm_usleep): Update docstring per manual, cross reference sleep.
299 * struct.c (scm_make_struct): Move SCM_CRITICAL_SECTION_END up so that
300 scm_struct_init is not within that section. scm_struct_init can
301 thrown an error, which within a critical section results in an
304 2007-02-19 Neil Jerram <neil@ossau.uklinux.net>
306 * Makefile.am (noinst_HEADERS): Add private-options.h, so that it
307 is included in the distribution.
308 (noinst_HEADERS): And the same for eval.i.c.
310 2007-01-31 Ludovic Courtès <ludovic.courtes@laas.fr>
312 * i18n.c: Include "libguile/threads.h" and "libguile/posix.h"
313 unconditionally. Include <langinfo.h> and <nl_types.h> when
315 (SCM_I18N_STRINGIFY, SCM_LOCALE_CATEGORY_MASK,
316 SCM_LIST_OR_INTEGER_P): New macros.
317 (LC_*_MASK): When `USE_GNU_LOCALE_API' is undefined, define them
318 as powers of two instead of `(1 << LC_*)'.
319 (scm_i_locale_free): New function/macro.
320 (scm_global_locale): New global variable.
321 (smob_locale_free): Use `scm_i_locale_free ()'.
322 (smob_locale_mark): Check whether the SMOB is `%global-locale'.
323 (get_current_locale_settings): Return `EINVAL' instead of `errno'
324 when `setlocale' fails.
325 (restore_locale_settings): Likewise.
326 (install_locale_categories): Likewise.
327 (install_locale): Likewise. Stop the locale stack traversal when
328 all categories have been handled.
329 (get_current_locale, category_to_category_mask,
330 category_list_to_category_mask): New function.
331 (scm_make_locale): Use them. Accept both lists of `LC_*' values
332 and single `LC_*' values as the first argument. Handle the case
333 where BASE_LOCALE is `%global-locale'. When `USE_GNU_LOCALE_API',
334 duplicate C_BASE_LOCALE before using it.
335 (scm_nl_langinfo, define_langinfo_items): New functions.
336 (scm_init_i18n): When `HAVE_NL_LANGINFO', add feature
337 `nl-langinfo' and invoke `define_langinfo_items ()'.
338 * i18n.h (scm_global_locale, scm_nl_langinfo): New declarations.
339 * posix.c: Include <xlocale.h> when available.
340 (scm_i_locale_mutex): Always define it. Statically initialized.
341 (scm_set_locale): Invoke `scm_i_to_lc_category ()' before
342 acquiring the locale mutex.
343 (scm_init_posix): No longer initialize SCM_I_LOCALE_MUTEX here.
345 2007-01-27 Kevin Ryde <user42@zip.com.au>
347 * ports.c (scm_port_line, scm_set_port_line_x), read.c
348 (scm_i_input_error, scm_lreadr, scm_lreadrecparen): Corrections to
349 port line number type, should be "long" not "int", as per line_number
350 field of scm_t_port. (Makes a difference only on 64-bit systems, and
351 only then for a linenum above 2Gig.)
353 2007-01-25 Han-Wen Nienhuys <hanwen@lilypond.org>
355 * vector.c: remove comment as per kryde's request.
357 2007-01-25 Kevin Ryde <user42@zip.com.au>
359 * sort.c (scm_stable_sort): Return empty list for input empty list, as
360 done in guile 1.6 and as always done by plain `sort'. Was falling
361 through to SCM_WRONG_TYPE_ARG. Reported by Ales Hvezda.
363 2007-01-22 Han-Wen Nienhuys <hanwen@lilypond.org>
365 * vectors.c (s_scm_vector_move_right_x): complain about naming.
367 * srcprop.c: regularize comments.
369 * eval.c: remove superfluous ifndef DEVAL.
371 * private-options.h: idem.
373 * eval.i.c: copyright nitpicking.
375 * eval.c: distangle. move duplicate code to eval.i.c and include
378 * eval.i.c: new file.
380 * backtrace.c, debug.c, debug.h, deprecation.c, eq.c, eval.c
381 eval.h, gsubr.c, init.c, macros.c, print.c, print.h, read.c,
382 read.h, stacks.c, symbols.c, throw.c: use private-options.h
384 * private-options.h: new file: contain hardcoded option
387 * private-gc.h: add FSF header.
389 2007-01-19 Han-Wen Nienhuys <hanwen@lilypond.org>
391 * debug.h (SCM_RESET_DEBUG_MODE): switch to debugging if
392 memoize-symbol is set.
394 * eval.h (SCM_MEMOIZE_HDLR): add macros for memoize symbol trap.
396 * eval.c (CEVAL): add memoize_symbol trap.
398 * options.c (scm_options_try): new function. This allows error
399 reporting before changing options in a critical section.
401 * srcprop.c: use double cell for storing source-properties. Put
402 filename in the plist, and share between srcprops if possible.
403 Remove specialized storage.
405 * srcprop.h: remove macros without SCM_ prefix from
406 interface. Remove specialized storage/type definitions.
412 * eval.c: terminate option lists with 0.
414 * options.c: remove n (for length) from scm_option_X
415 functions. Detect option list length by looking for NULL name.
417 2007-01-19 Ludovic Courtès <ludovic.courtes@laas.fr>
419 * struct.c (scm_i_struct_equalp): Skip comparison if both FIELD1
420 is equal to S1 and FIELD2 is equal to S2. This avoids infinite
421 recursion when comparing `s' fields, as the REQUIRED_VTABLE_FIELDS
422 added by `make-vtable-vtable'. Reported by Marco Maggi.
424 2007-01-18 Han-Wen Nienhuys <hanwen@lilypond.org>
426 * throw.c (scm_ithrow): more refined error message: print symbols
429 2007-01-16 Kevin Ryde <user42@zip.com.au>
431 * feature.c, feature.h (scm_set_program_arguments_scm): New function,
432 implementing `set-program-arguments'.
434 * filesys.c (scm_init_filesys): Use scm_from_int rather than
435 scm_from_long for O_RDONLY, O_WRONLY, O_RDWR, O_CREAT, O_EXCL,
436 O_NOCTTY, O_TRUNC, O_APPEND, O_NONBLOCK, O_NDELAY, O_SYNC and
437 O_LARGEFILE. These are all int not long, per arg to open().
438 (scm_init_filesys): Use scm_from_int rather than scm_from_long for
439 F_DUPFD, F_GETFD, F_SETFD, F_GETFL, F_SETFL, F_GETOWN, F_SETOWN, these
440 are all ints (per command arg to fcntl). Likewise FD_CLOEXEC which is
443 * posix.c (scm_putenv): Correction to "len" variable, was defined only
444 for __MINGW32__ but used under any !HAVE_UNSETENV (such as solaris).
445 Move it to where it's used. Reported by Hugh Sasse.
447 * regex-posix.c (scm_regexp_exec): Remove SCM_CRITICAL_SECTION_START
448 and SCM_CRITICAL_SECTION_END, believe not needed. Their placement
449 meant #\nul in the input (detected by scm_to_locale_string) and a bad
450 flags arg (detected by scm_to_int) would throw from a critical
451 section, causing an abort().
453 * regex-posix.c (scm_init_regex_posix): Use scm_from_int for
454 REG_BASIC, REG_EXTENDED, REG_ICASE, REG_NEWLINE, REG_NOTBOL,
455 REG_NOTEOL; they're all ints not longs (per args to regcomp and
458 2007-01-10 Han-Wen Nienhuys <hanwen@lilypond.org>
460 * throw.c (scm_ithrow): print out key symbol and string arguments
461 when error happens inside a critical section, and document why.
463 2007-01-06 Han-Wen Nienhuys <hanwen@lilypond.org>
465 * read.c (s_scm_read_hash_extend): document #f argument to
468 2007-01-04 Kevin Ryde <user42@zip.com.au>
470 * deprecated.h (scm_create_hook), version.h.in (scm_major_version,
471 scm_minor_version, scm_micro_version, scm_effective_version,
472 scm_version, scm_init_version): Use SCM_API instead of just extern,
473 for the benefit of mingw. Reported by Cesar Strauss.
475 2007-01-03 Han-Wen Nienhuys <hanwen@lilypond.org>
477 * gc.c (s_scm_gc_stats): return an entry for total-cells-allocated
479 (gc_update_stats): update scm_gc_cells_allocated_acc too.
481 2006-12-27 Kevin Ryde <user42@zip.com.au>
483 * threads.c (get_thread_stack_base): In mingw with pthreads we can use
484 the basic scm_get_stack_base. As advised by Nils Durner.
486 * threads.c (get_thread_stack_base): Add a version using
487 pthread_get_stackaddr_np (when available), for the benefit of MacOS.
488 As advised by Heikki Lindholm.
490 * scmsigs.c (signal_delivery_thread): Restrict scm_i_pthread_sigmask
491 to HAVE_PTHREAD_SIGMASK, it doesn't exist on mingw. Reported by Nils
494 2006-12-24 Kevin Ryde <user42@zip.com.au>
496 * posix.c (scm_kill): When only raise() is available, throw an ENOSYS
497 error if pid is not our own process, instead of silently doing nothing.
499 * print.c (scm_write, scm_display, scm_write_char): Disable port close
500 on EPIPE. This was previously disabled but introduction of HAVE_PIPE
501 check in configure.in unintentionally enabled it. Believe that
502 testing errno after scm_prin1 or scm_putc is bogus, a long ago error
503 can leave errno in that state. popen.test "no duplicates" output test
506 2006-12-23 Han-Wen Nienhuys <hanwen@lilypond.org>
508 * numbers.c (scm_i_fraction_reduce): move logic into
509 scm_i_make_ratio(), so fractions are only read.
510 scm_i_fraction_reduce() modifies a fraction when reading it. A
511 race condition might lead to fractions being corrupted by reading
514 Also, the REDUCED bit alters the SCM_CELL_TYPE(), making
515 comparisons between reduced and unreduced fractions go wrong.
517 * numbers.h: remove SCM_FRACTION_SET_NUMERATOR,
518 SCM_FRACTION_SET_DENOMINATOR, SCM_FRACTION_REDUCED_BIT,
519 SCM_FRACTION_REDUCED_SET, SCM_FRACTION_REDUCED_CLEAR,
520 SCM_FRACTION_REDUCED.
522 2006-12-16 Kevin Ryde <user42@zip.com.au>
524 * scmsigs.c (scm_raise): Use raise() rather than kill(), as this is
525 more direct for a procedure called raise.
526 (kill): Remove mingw fake fallback.
528 2006-12-15 Kevin Ryde <user42@zip.com.au>
530 * scmsigs.c: Conditionalize process.h, add io.h believe needed for
533 2006-12-14 Kevin Ryde <user42@zip.com.au>
535 * threads.c (thread_print): Cope with the case where pthread_t is a
536 struct, as found on mingw. Can't just cast to size_t for printing.
537 Reported by Nils Durner.
539 * scmsigs.c: Add <fcntl.h> and <process.h> needed by mingw. Copy the
540 fallback pipe() using _pipe() from posix.c. Reported by Nils Durner.
542 2006-12-13 Kevin Ryde <user42@zip.com.au>
544 * eval.c (scm_m_define): Set 'name procedure property on any
545 scm_procedure_p, not just SCM_CLOSUREP. In particular this picks up
546 procedures with setters as used in srfi-17.
548 * posix.c (scm_crypt): Check for NULL return from crypt(), which the
549 linux man page says is a possibility.
551 2006-12-12 Ludovic Courtès <ludovic.courtes@laas.fr>
553 * libguile/unif.c (read_decimal_integer): Let RESP be SIGN * RES
554 instead of RES (reported by Szavai Gyula). This allows the use of
555 negative lower bounds.
556 (scm_i_read_array): Make sure LEN is non-negative (reported by
559 (scm_array_in_bounds_p): Iterate over S instead of always
560 comparing indices with the bounds of S[0]. This fixes
561 `array-in-bounds?' for arrays with a rank greater than one and
562 with different lower bounds for each dimension.
564 2006-12-05 Kevin Ryde <user42@zip.com.au>
566 * numbers.c (scm_product): For flonum*inum and complex*inum, return
567 exact 0 if inum==0. Already done for inum*flonum and inum*complex,
568 and as per R5RS section "Exactness".
570 2006-12-03 Kevin Ryde <user42@zip.com.au>
572 * Makefile.am (.c.doc): Remove the "test -n" apparently attempting to
573 allow $AWK from the environment to override. It had syntax gremlins,
574 and the presence of a $(AWK) variable set by AC_PROG_AWK in the
575 Makefile stopped it having any effect. Use just $(AWK), which can be
576 overridden with "make AWK=xxx" in the usual way if desired.
578 2006-11-29 Ludovic Courtès <ludovic.courtes@laas.fr>
580 * libguile/vectors.c (scm_vector_to_list): Fixed list
581 construction: elements were not copied when INC is zero (see
582 "shared array" example in `vectors.test'). Reported by
585 2006-11-18 Ludovic Courtès <ludovic.courtes@laas.fr>
587 * Makefile.am (lib_LTLIBRARIES): Added `libguile-i18n-v-XX.la'.
588 (libguile_la_SOURCES): Added `gettext.c', removed `i18n.c'.
589 (libguile_i18n_v_XX_la_SOURCES, libguile_i18n_v_XX_la_CFLAGS,
590 libguile_i18n_v_XX_la_LIBADD, libguile_i18n_v_XX_la_LDFLAGS): New.
591 (DOT_X_FILES): Added `gettext.x'.
592 (DOT_DOC_FILES): Likewise.
593 (EXTRA_libguile_la_SOURCES): Added `locale-categories.h'.
594 (modinclude_HEADERS): Added `gettext.h'.
595 (EXTRA_DIST): Added `libgettext.h'.
597 * gettext.h: Renamed to...
598 * libgettext.h: New file.
600 * i18n.c: Renamed to...
601 * gettext.c: New file.
603 * i18n.h: Renamed to...
604 * gettext.h: New file.
606 * i18n.c, i18n.h, locale-categories.h: New files.
608 * init.c: Include "libguile/gettext.h" instead of
610 (scm_i_init_guile): Invoke `scm_init_gettext ()' instead of
613 * posix.c: Include "libguile/gettext.h" instead of
614 "libguile/i18n.h" Test `HAVE_NEWLOCALE' and `HAVE_STRCOLL_L'.
615 (USE_GNU_LOCALE_API): New macro.
616 (scm_i_locale_mutex): New variable.
617 (scm_setlocale): Lock and unlock it around `setlocale ()' calls.
619 * posix.h: Include "libguile/threads.h".
620 (scm_i_locale_mutex): New declaration.
622 2006-11-17 Neil Jerram <neil@ossau.uklinux.net>
624 * script.c (scm_shell_usage): Note need for subscription to bug-guile@gnu.org.
626 2006-11-08 Ludovic Courtès <ludovic.courtes@laas.fr>
628 * libguile/gc-freelist.c (scm_i_adjust_min_yield): Take two
629 "sweep_stats" arguments; use them instead of accessing the global
630 variables `scm_gc_cells_collected' and `scm_gc_cells_collected_1'.
632 * libguile/gc-segment.c (scm_i_sweep_some_cards): Reset SWEEP
633 before each iteration of the loop.
634 (scm_i_sweep_some_segments): Reset SWEEP at each iteration.
635 (scm_i_get_new_heap_segment): Take an additional argument
636 SWEEP_STATS. Compute MIN_CELLS as a function of it.
638 * libguile/gc.c (scm_gc_cells_collected,
639 scm_gc_cells_collected_1): Removed.
640 (scm_i_gc_sweep_stats, scm_i_gc_sweep_stats_1): New.
641 (scm_gc_cells_marked_acc, scm_gc_cells_swept_acc,
642 scm_gc_time_taken, scm_gc_mark_time_taken, scm_gc_times,
643 scm_gc_cell_yield_percentage, protected_obj_count): Made `static'.
644 (scm_gc_stats): Use `scm_i_gc_sweep_stats' instead of
645 `scm_gc_cells_(collected|swept)'.
646 (gc_update_stats): New.
647 (gc_end_stats): Use `scm_i_gc_sweep_stats' and
648 `scm_i_gc_sweep_stats_1' instead of the former globals.
649 (scm_gc_for_newcell): Invoke `gc_update_stats ()' after each
650 `scm_i_sweep_some_segments' call. This fixes a bug where the GC
651 would keep allocating new segments instead of re-using collected
652 cells (because `scm_gc_cells_collected' would remain zero).
654 * libguile/gc.h (scm_gc_cells_swept, scm_gc_cells_collected,
655 scm_gc_cell_yield_percentage): Removed.
657 * libguile/private-gc.h (scm_gc_cells_collected_1): Removed.
658 (scm_i_adjust_min_yield): Updated.
659 (scm_i_get_new_heap_segment): Updated.
661 2006-11-02 Neil Jerram <neil@ossau.uklinux.net>
663 * modules.c: Correct comment saying that low-level environments
664 will be used "in the next release".
666 * init.c: Comment out #include of environments.h.
667 (scm_i_init_guile): Comment out scm_environments_prehistory() and
668 scm_init_environments() calls.
670 * Makefile.am (libguile_la_SOURCES): Remove environments.c.
671 (DOT_X_FILES): Remove environments.x.
672 (DOT_DOC_FILES): Remove environments.doc.
673 (modinclude_HEADERS): Remove environments.h.
675 2006-10-25 Neil Jerram <neil@ossau.uklinux.net>
677 IA64 HP-UX GC patch from Hrvoje Nikšić. (Thanks!)
679 * threads.c (SCM_MARK_BACKING_STORE): Use scm_ia64_ar_bsp() and
680 scm_ia64_register_backing_store_base() instead of Linux-specific
683 * gc.h (scm_ia64_register_backing_store_base, scm_ia64_ar_bsp):
686 * gc.c (__libc_ia64_register_backing_store_base): Declaration
688 (scm_ia64_register_backing_store_base, scm_ia64_ar_bsp): New, with
689 implementations for Linux and HP-UX.
691 * coop-pthreads.c (SCM_MARK_BACKING_STORE): Use scm_ia64_ar_bsp()
692 and scm_ia64_register_backing_store_base() instead of
693 Linux-specific implementations.
695 * continuations.h (__libc_ia64_register_backing_store_base):
697 (scm_t_contregs): New "fresh" field.
699 * continuations.c (ia64_getcontext): Removed.
700 (scm_make_continuation): Use continuation fresh field instead of
701 interpreting getcontext return values (which isn't portable). Use
702 scm_ia64_ar_bsp() and scm_ia64_register_backing_store_base()
703 instead of Linux-specific implementations.
704 (copy_stack_and_call): Use scm_ia64_register_backing_store_base()
705 instead of Linux-specific implementation.
707 * _scm.h (__ia64__): Also detect __ia64.
709 2006-10-03 Kevin Ryde <user42@zip.com.au>
711 * eval.c (SCM_APPLY): For scm_tc7_subr_2o, throw wrong-num-args on 0
712 arguments or 3 or more arguments. Previously 0 called proc with
713 SCM_UNDEFINED, and 3 or more silently used just the first 2.
715 2006-09-28 Kevin Ryde <user42@zip.com.au>
717 * fports.c, ports.c (ftruncate): Use "HAVE_CHSIZE && ! HAVE_FTRUNCATE"
718 for chsize fallback, instead of hard-coding mingw. Mingw in fact
719 supplies ftruncate itself these days.
721 * ports.c (fcntl.h): Can include this unconditionally, no need for
724 * ports.c (truncate): Conditionalize on "HAVE_FTRUNCATE && !
725 HAVE_TRUNCATE" so as not to hard-code mingw. Use "const char *" and
726 "off_t" for parameters, per usual definition of this function, rather
727 than "char *" and "int". Use ftruncate instead of chsize. Check for
728 error on final close.
730 2006-09-27 Kevin Ryde <user42@zip.com.au>
732 * numbers.c (scm_log10): Check HAVE_CLOG10, clog10() is not available
735 * posix.c (scm_execl, scm_execlp, scm_execle): Cast "const char *
736 const *" for mingw to suppress warnings from gcc (which are errors
737 under the configure default -Werror). Reported by Nils Durner.
739 2006-09-26 Kevin Ryde <user42@zip.com.au>
741 * _scm.h (scm_to_off64_t, scm_from_off64_t): New macros.
742 * fports.c (scm_open_file): Use open_or_open64.
743 (fport_seek_or_seek64): New function, adapting fport_seek.
744 * fports.c, fports.h (scm_i_fport_seek, scm_i_fport_truncate): New
746 * ports.c (scm_seek, scm_truncate_file): Use scm_i_fport_seek and
747 scm_i_fport_truncate to allow 64-bit seeks and truncates on fports.
749 * ports.c (scm_truncate_file): Update docstring per manual.
751 2006-09-23 Kevin Ryde <user42@zip.com.au>

756 2006-09-20 Ludovic Courtès <ludovic.courtes@laas.fr>
758 * srfi-14.c: Include <config.h>. Define `_GNU_SOURCE'.
759 (make_predset, define_predset, make_strset, define_strset, false,
761 (SCM_CHARSET_UNSET, CSET_BLANK_PRED, CSET_SYMBOL_PRED,

765 CSET_LETTER_AND_DIGIT_PRED, CSET_GRAPHIC_PRED, CSET_PRINTING_PRED,
766 CSET_TRUE_PRED, CSET_FALSE_PRED, UPDATE_CSET): New macros.
767 (define_charset, scm_srfi_14_compute_char_sets): New functions.
768 (scm_init_srfi_14): Use `define_charset ()' instead of
769 `define_predset ()' and `define_strset ()'.
771 * srfi-14.h (scm_c_init_srfi_14): Removed.
772 (scm_srfi_14_compute_char_sets): New declaration.
774 * posix.h: Include "srfi-14.h".
775 (scm_setlocale): Invoke `scm_srfi_14_compute_char_sets ()' after a
776 successful `setlocale ()' call.
778 2006-09-08 Kevin Ryde <user42@zip.com.au>
780 * socket.c (scm_init_socket): Add MSG_DONTWAIT.
781 (scm_recvfrom): Update docstring from manual.
783 2006-08-31 Rob Browning <rlb@defaultvalue.org>
785 * ports.c (scm_c_port_for_each): Add a
786 scm_remember_upto_here_1(ports) at the end of the function to fix
789 2006-08-28 Neil Jerram <neil@ossau.uklinux.net>
791 * backtrace.c (scm_display_backtrace_with_highlights): Minor
792 improvements to docstring.
793 (scm_backtrace_with_highlights): Analogous improvements.
795 2006-08-12 Kevin Ryde <user42@zip.com.au>
797 * gen-scmconfig.h.in (SCM_I_GSC_NEED_BRACES_ON_PTHREAD_ONCE_INIT):
798 New, set from configure.
799 * gen-scmconfig.c (SCM_NEED_BRACES_ON_PTHREAD_ONCE_INIT): New output
801 * pthread-threads.h (SCM_I_PTHREAD_ONCE_INIT): Use
802 SCM_NEED_BRACES_ON_PTHREAD_ONCE_INIT to cope with Solaris.
803 Reported by Claes Wallin.
805 2006-08-11 Neil Jerram <neil@ossau.uklinux.net>
807 * stacks.c (scm_last_stack_frame): Correct docstring (returns a
810 2006-07-25 Kevin Ryde <user42@zip.com.au>
812 * threads.c (get_thread_stack_base): Restrict HAVE_PTHREAD_GETATTR_NP
813 on pthreads version, since pthread_getattr_np not available on solaris
814 and macos. Reported by Claes Wallin.
816 2006-07-24 Kevin Ryde <user42@zip.com.au>
818 * filesys.c (dirfd): Test with #ifndef rather than HAVE_DIRFD, since
819 it's a macro on MacOS X. Reported by Claes Wallin.
821 * posix.c (sethostname): Give prototype if not HAVE_DECL_SETHOSTNAME,
822 for the benefit of Solaris 10. Reported by Claes Wallin.
824 * socket.c (scm_htonl, scm_ntohl): Use scm_to_uint32 rather than
825 NUM2ULONG, to enforce 32-bit range check on systems with 64-bit long.
827 2006-07-21 Kevin Ryde <user42@zip.com.au>
829 * eval.c, filesys.c (alloca): Update <alloca.h> etc blob, per current
830 autoconf recommendation. Should fix Solaris 10 reported by Claes
833 * threads.c: Include <string.h>, needed for memset() which is used by
834 FD_ZERO() on Solaris 10. Reported by Claes Wallin.
836 2006-07-18 Rob Browning <rlb@defaultvalue.org>
838 * continuations.c: Add __attribute__ ((returns_twice)) to the
839 ia64_getcontext prototype so that gcc will make the right
840 arrangements and avoid an illegal instruction during
841 call-with-current-continuation.
843 2006-07-12 Ludovic Courtès <ludovic.courtes@laas.fr>
845 * numbers.c (guile_ieee_init): Use regular ANSI C casts rather
846 than C++-style `X_CAST ()'. Patch posted by by Mike Gran.
848 2006-07-08 Kevin Ryde <user42@zip.com.au>
850 * environments.c (core_environments_unobserve): Use if/else rather
851 than ?: for "SET" bits, avoiding complaints from AIX xlc compiler
852 about them not being rvalues. Reported by Mike Gran.
854 * Makefile.am (version.h): Don't use $< in an explicit rule, it's not
855 portable and in particular fails on OpenBSD and AIX (see autoconf
856 manual too). Reported by Mike Gran.
858 2006-06-25 Kevin Ryde <user42@zip.com.au>
860 * stime.c (bdtime2c): tm_gmtoff is seconds East, so take negative of
861 tm:gmtoff which is seconds West. Reported by Aaron VanDevender.
862 (bdtime2c): Test HAVE_STRUCT_TM_TM_GMTOFF for tm_gmtoff, rather than
864 (scm_strptime): Use tm_gmtoff from the strptime result when that field
865 exists, it's set by glibc strptime "%s".
867 2006-06-13 Ludovic Courtès <ludovic.courtes@laas.fr>
869 * eq.c: Include "struct.h", "goops.h" and "objects.h".
870 (scm_equal_p): Invoke `scm_i_struct_equalp ()' on structures that
871 are not GOOPS instances.
872 * struct.c: Include "eq.h".
873 (scm_free_structs): Use `SCM_STRUCT_VTABLE_DATA ()' instead of
875 (scm_i_struct_equalp): New.
876 * struct.h (scm_i_struct_equalp): New declaration.
878 2006-06-06 Kevin Ryde <user42@zip.com.au>
880 * Makefile.am (BUILT_SOURCES): Remove guile.texi, only used by
881 maintainers (with doc/maint/docstring.el). Fixes parallel "make -j2"
882 reported by Mattias Holm.
884 2006-06-03 Kevin Ryde <user42@zip.com.au>
886 * read.c (s_vector): Conditionalize on SCM_ENABLE_ELISP, to avoid
887 unused variable warning when elisp disabled. Reported by Ryan
890 * throw.c (scm_handle_by_message): Add dummy return value to avoid
891 compiler warning on cygwin. Reported by Ryan VanderBijl.
893 * Makefile.am (EXTRA_DOT_X_FILES): Typo in dependency rule, was a
894 duplicate of EXTRA_DOT_DOC_FILES.
895 (DOT_X_FILES, EXTRA_DOT_X_FILES, DOT_DOC_FILES, EXTRA_DOT_DOC_FILES):
896 Add scmconfig.h to dependencies, since these all run cpp. Helps a
897 parallel "make -j2". Reported by Mattias Holm.
899 2006-05-30 Kevin Ryde <user42@zip.com.au>
901 * ports.c, ports.h (scm_set_port_mark, scm_set_port_free,
902 scm_set_port_print, scm_set_port_equalp, scm_set_port_flush,
903 scm_set_port_end_input, scm_set_port_close, scm_set_port_seek,
904 scm_set_port_truncate, scm_set_port_input_waiting): Use scm_t_bits for
905 port type descriptor, same as scm_make_port_type return value.
907 2006-05-30 Marius Vollmer <mvo@zagadka.de>
909 * eq.c (scm_equal_p): Use scm_array_equal_p explicitely when one
910 of the arguments is a array. This allows vectors to be equal to
911 one-dimensional arrays.
913 2006-05-29 Marius Vollmer <mvo@zagadka.de>
915 * throw.c (scm_ithrow): When looking for the jmpbuf, first test
916 that we have a pair before accessing its cdr. Thanks to Bill
919 2006-05-28 Kevin Ryde <user42@zip.com.au>
921 * eval.c, filesys.c: Add malloc.h to get alloca() on mingw. Reported
924 2006-05-27 Marius Vollmer <mvo@zagadka.de>
926 * srfi-4.c, strings.c: Replace SCM_C_INLINE with
927 SCM_C_INLINE_KEYWORD. Thanks to Mark Gran!
929 2006-05-26 Kevin Ryde <user42@zip.com.au>
931 * fports.c (fport_input_waiting): For ioctl, check HAVE_IOCTL as well
932 as defined(FIONREAD), since mingw has FIONREAD but not ioctl().
933 Reported by "The Senator".
934 For select and ioctl, move fdes into those conditionals, to avoid
935 unused variable warning when neither of those used.
937 2006-05-23 Kevin Ryde <user42@zip.com.au>
939 * fports.c: Remove "fwrite" declaration under "! HAVE_UNISTD_H".
940 It's unused and will be in stdio.h anyway (if it's anywhere).
942 2006-05-20 Kevin Ryde <user42@zip.com.au>
944 * filesys.c (scm_stat2scm): Test #ifdef S_ISLNK directly, rather than
945 HAVE_S_ISLNK from configure (it was only a #ifdef test anyway).
947 * posix.c (scm_mknod): Test #ifdef S_IFLNK before using that (for
948 symlink). Probably can't create symlinks with mknod anyway though.
950 * inline.h (scm_is_pair): Add a workaround for i386 gcc 2.95 bad code
953 2006-05-15 Kevin Ryde <user42@zip.com.au>
955 * simpos.c, simpos.h (scm_primitive__exit): New function.
956 (scm_primitive_exit): Update docstring, no longer the best exit after
959 2006-05-09 Kevin Ryde <user42@zip.com.au>
961 * numbers.c (scm_i_divide): For big/big wanting inexact, use mpq_get_d
962 rather than converting to doubles, to avoid inf or nan when the inputs
963 are too big for a double but the quotient does fit. This affects
964 conversions exact->inexact of big fractions.
966 * filesys.c (scm_open_fdes): Use open64.
967 (scm_init_filesys): Add O_LARGEFILE.
969 * ports.c (scm_seek): Use lseek64.
970 (scm_truncate_file): Use ftruncate64.
972 2006-05-08 Marius Vollmer <mvo@zagadka.de>
974 * private-gc.h (CELL_P): Also check that the potential pointer is
975 correctly aligned for a cell. Thanks to Miroslav Lichvar!
977 2006-04-18 Rob Browning <rlb@defaultvalue.org>
979 * _scm.h: Add back error if the size of off_t is unknown. The bug
980 was actually in guile-readline's configuration.
982 2006-04-18 Kevin Ryde <user42@zip.com.au>
984 * posix.c (scm_mkstemp): Update docstring from the manual, in
985 particular file mode 0600 is not guaranteed.
987 2006-04-17 Kevin Ryde <user42@zip.com.au>
989 * _scm.h (scm_to_off_t, scm_from_off_t): No error if unknown off_t
990 size, to help the guile-readline build where off_t is unused.
992 2006-04-16 Kevin Ryde <user42@zip.com.au>
994 * filesys.c (scm_stat2scm, scm_stat, scm_lstat): Use stat or stat64.
995 (scm_readdir): Use readdir64.
996 (scm_copy_file): Use open64 and fstat64, to cope with >2Gb files.
997 * ports.c (scm_truncate_file): Use truncate64. Correction truncate
998 and ftruncate take off_t not size_t.
999 * _scm.h (stat_or_stat64 etc): Macros for selecting LFS64 when
1002 2006-04-06 Kevin Ryde <user42@zip.com.au>
1004 * fports.c (scm_setvbuf): Fix for not _IOLBF, clear SCM_BUFLINE
1005 instead of toggling it. Reported by Ludovic Courtès.
1007 2006-03-26 Marius Vollmer <mvo@zagadka.de>
1009 * threads.c (get_thread_stack_base): Use scm_get_stack_base
1010 instead of accessing __libc_stack_end directly, and only do this
1011 when pthread_attr_getstack is known not to work for the main
1012 thread or when not using pthreads at all.
1014 * gc_os_dep.c (scm_get_stack_base): Abort when the machine type is
1015 unknown instead of returning NULL.
1017 2006-03-21 Ludovic Courtès <ludovic.courtes@laas.fr>
1019 * numbers.c (scm_i_mem2number): Renamed to
1020 scm_c_locale_stringn_to_number.
1021 * numbers.c, print.c, read.c: Updated callers.
1022 * numbers.h: Update function declaration.
1024 2006-03-11 Neil Jerram <neil@ossau.uklinux.net>
1026 * unif.c (string_set): Don't return in a void function. (Reported
1029 * srfi-4.c (scm_uniform_vector_read_x): Declare base as char*
1030 rather than void*, so we can do pointer arithmetic on it.
1031 (Reported by Mike Gran.)
1032 (s_scm_uniform_vector_write): Ditto.
1034 2006-03-10 Neil Jerram <neil@ossau.uklinux.net>
1036 * unif.c (scm_make_shared_array): Don't use SCM_I_ARRAY_BASE when
1037 oldra is not an array. (Reported by Steve Juranich.)
1039 * threads.c (do_unlock): Renamed from "unlock", which is defined
1040 in unistd.h on QNX. (Reported by Matt Kraai.)
1042 2006-03-04 Kevin Ryde <user42@zip.com.au>
1044 * deprecated.c (scm_i_defer_ints_etc): Show SCM_DEFER_INTS in message,
1045 not SCM_CRITICAL_SECTION_START.
1047 * eval.c, posix.c: Change comments from C++ to C style. Reported by
1050 2006-02-28 Kevin Ryde <user42@zip.com.au>
1052 * unif.c (bitvector_set): Use h->writable_elements not h->elements.
1054 2006-02-26 Kevin Ryde <user42@zip.com.au>
1056 * filesys.c (scm_readdir): Use fpathconf for the dirent size when
1057 NAME_MAX is not available, which is so on Solaris 10. Report and help
1058 by Bill Schottstaedt.
1060 * srfi-13.c (MY_VALIDATE_SUBSTRING_SPEC_UCOPY): New macro.
1061 (scm_string_compare, scm_string_compare_ci, scm_string_lt,
1062 scm_string_gt, scm_string_le, scm_string_ge, scm_string_ci_lt,
1063 scm_string_ci_gt, scm_string_ci_le, scm_string_ci_ge): In comparisons
1064 use "unsigned char", not signed char. This ensures comparisons are
1065 the same as `char<?' etc, and is also the same as guile 1.6 did.
1066 Reported by Sven Hartrumpf.
1068 2006-02-19 Mikael Djurfeldt <mdj@neurologic.cc>
1070 * random.c: Test for SCM_HAVE_T_UINT64 instead of
1072 (scm_i_uniform32, scm_i_uniform32, scm_i_init_rstate): Use
1073 scm_t_uint64 and scm_t_uint32 instead of scm_t_int64 and
1076 2006-01-04 Ludovic Courtès <ludovic.courtes@laas.fr>
1078 * gc-segment.c (scm_i_sweep_some_cards): Take a SWEEP_STATS
1079 argument. Don't refer to SCM_GC_CELLS_COLLECTED and
1080 SCM_CELLS_ALLOCATED. If SEG->FIRST_TIME, let CELLS_COLLECTED as zero.
1081 Take into account SEG->SPAN when computing CELLS_SWEPT.
1082 (scm_i_sweep_segment): Take one more argument, similarly.
1083 (scm_i_sweep_all_segments): Likewise.
1084 (scm_i_sweep_some_segments): Likewise.
1085 (scm_i_adjust_min_yield): Change the way MIN_CELLS is computed: do not
1086 refer to SCM_GC_CELLS_COLLECTED.
1088 * gc-freelist.c (scm_i_adjust_min_yield): Take one more
1089 argument, an `scm_i_sweep_statistics' object.
1090 Change the way DELTA is collected: don't take into account
1091 SCM_GC_CELLS_COLLECTED_1, only SWEEP_STATS.COLLECTED.
1093 * gc-malloc.c (scm_realloc): Pass an extra argument
1094 to `scm_i_sweep_all_segments ()'.
1096 * gc.c (gc_start_stats): Updated accordingly.
1097 (gc_end_stats): Take an additional SWEEP_STATS argument.
1098 Decrement SCM_CELLS_ALLOCATED after calls to `scm_i_sweep_* ()'.

1100 Decrement SCM_CELLS_ALLOCATED.
1101 (scm_i_gc): Likewise.
1103 * private-gc.h (scm_i_sweep_*): Updated function
1104 prototypes accordingly.
1105 (scm_t_sweep_statistics): New type.

1107 (scm_i_sweep_statistics_sum): New macro
1109 2006-02-14 Ludovic Courtès <ludovic.courtes@laas.fr>
1111 * strings.c (scm_i_take_stringbufn): Register LEN+1 bytes instead of
1112 LEN. Without this, too much collectable memory gets unregistered,
1113 which results in an underflow of SCM_MALLOCATED in
1114 `decrease_mtrigger()'.
1116 * gc-malloc.c (decrease_mtrigger): Make sure SIZE is lower than or
1117 equal to SCM_MALLOCATED.
1119 2006-02-13 Marius Vollmer <mvo@zagadka.de>
1121 * eval.c (scm_eval_body): Use scm_i_dynwind_pthread_mutex_lock
1122 oinstead of scm_dynwind_pthread_mutex_lock so that it works when
1123 configured --without-threads.
1124 (SCM_APPLY, CEVAL): Likewise. Thanks to Han-Wen Nienhuys!
1126 2006-02-12 Marius Vollmer <mvo@zagadka.de>
1128 * unif.c (scm_dimensions_to_uniform_array): Use the prototype for
1129 filling when the fill parameter is omitted, as documented, but
1130 turn #\nul into 0 since s8 arrays (signified by a #\nul prototype)
1131 can not store characters.
1133 2006-02-09 Neil Jerram <neil@ossau.uklinux.net>
1135 * socket.c (scm_c_make_socket_address): Pass address_size pointer
1136 on to scm_fill_sockaddr call.
1138 2006-02-04 Neil Jerram <neil@ossau.uklinux.net>
1140 * throw.h (scm_c_catch, scm_c_with_throw_handler,
1141 scm_catch_with_pre_unwind_handler, scm_with_throw_handler): New.
1143 * throw.c (SCM_JBPREUNWIND, SCM_SETJBPREUNWIND): New.
1144 (struct pre_unwind_data): New, replaces struct lazy_catch.
1145 (scm_c_catch): New, replaces scm_internal_catch as the primary
1146 catch API for C code; adds pre-unwind handler support.
1147 (scm_internal_catch): Now just a wrapper for scm_c_catch, for back
1149 (tc16_pre_unwind_data, pre_unwind_data_print,
1150 make_pre_unwind_data, SCM_PRE_UNWIND_DATA_P): Renamed from
1151 "lazy_catch" equivalents.
1152 (scm_c_with_throw_handler): New, replaces scm_internal_lazy_catch
1153 as the primary C API for a "lazy" catch.
1154 (scm_internal_lazy_catch): Now just a wrapper for
1155 scm_c_with_throw_handler, for back compatibility.
1156 (scm_catch_with_pre_unwind_handler): Renamed from scm_catch; adds
1157 pre-unwind handler support.
1158 (scm_catch): Now just a wrapper for
1159 scm_catch_with_pre_unwind_handler, for back compatibility.
1160 (scm_with_throw_handler): New.
1161 (scm_lazy_catch): Update comment to say that the handler can
1162 return, and what happens if it does.
1163 (toggle_pre_unwind_running): New.
1164 (scm_ithrow): When identifying the throw target, take running
1165 flags into account. In general, change naming of things from
1166 "lazy_catch" to "pre_unwind". When throwing to a throw handler,
1167 don't unwind the dynamic context first. Add dynwind framing to
1168 manage the running flag of a throw handler. If a lazy catch or
1169 throw handler returns, rethrow the same exception again. Add
1170 pre-unwind support to the normal catch case (SCM_JMPBUFP).
1172 * root.c (scm_internal_cwdr): Add NULL args to
1173 scm_i_with_continuation_barrier call.
1175 * dynwind.c: Change comment mentioning lazy-catch to mention
1176 pre-unwind data and throw handler also.
1178 * continuations.h (scm_i_with_continuation_barrier): Add
1179 pre-unwind handler args.
1181 * continuations.c (scm_i_with_continuation_barrier): Add
1182 pre-unwind handler args, and pass on to scm_c_catch (changed from
1183 scm_internal_catch).
1184 (c_handler): Remove scm_handle_by_message_noexit call.
1185 (scm_c_with_continuation_barrier): Call
1186 scm_i_with_continuation_barrier with scm_handle_by_message_noexit
1187 as the pre-unwind handler.
1188 (scm_handler): Remove scm_handle_by_message_noexit call.
1189 (s_scm_with_continuation_barrier): Call
1190 scm_i_with_continuation_barrier with scm_handle_by_message_noexit
1191 as the pre-unwind handler.
1193 2006-02-04 Kevin Ryde <user42@zip.com.au>
1195 * gc-mark.c (scm_mark_all): Fix c99-isms "loops" and "again" variables.
1197 2006-02-03 Kevin Ryde <user42@zip.com.au>
1199 * list.c, list.h (scm_list): Restore this function for use from C.
1200 It's a complete no-op but in theory might used by someone.
1202 2006-01-30 Marius Vollmer <mvo@zagadka.de>
1204 * eval.c (scm_eval_body): Lock source_mutex with a dynwind context
1205 so that it gets unlocked in all cases.
1206 (SCM_APPLY, CEVAL): Likewise.
1208 2006-01-29 Marius Vollmer <mvo@zagadka.de>
1210 * ramap.c: (scm_array_map_x): Don't use scm_array_p, use
1211 scm_is_typed_array instead.
1213 Renamed the "frames" that are related to dynamic-wind to "dynamic
1214 contexts. Renamed all functions from scm_frame_ to scm_dynwind_.
1215 Updated documentation.
1219 * futures.h, futures.c: Wrap whole contents in "#if 0"/"#endif".
1220 * eval.c, init.c: Comment out all 'future' related things.
1222 2006-01-28 Marius Vollmer <mvo@zagadka.de>
1224 * inline.h, pairs.c (scm_is_pair): Moved scm_is_pair from pairs.c
1225 to inline.h to make it inline.
1227 2005-12-19 Ludovic Courtès <ludovic.courtes@laas.fr>
1229 * strings.c (scm_i_take_stringbufn): New.
1230 (scm_i_c_take_symbol): New.
1231 (scm_take_locale_stringn): Use `scm_i_take_stringbufn ()'.
1233 * strings.h (scm_i_c_take_symbol): New.
1234 (scm_i_take_stringbufn): New.
1236 * symbols.c (lookup_interned_symbol): New function.
1237 (scm_i_c_mem2symbol): New function.
1238 (scm_i_mem2symbol): Use `lookup_symbol ()'.
1239 (scm_from_locale_symbol): Use `scm_i_c_mem2symbol ()'. This avoids
1240 creating a new Scheme string.
1241 (scm_from_locale_symboln): Likewise.
1242 (scm_take_locale_symbol): New.
1243 (scm_take_locale_symboln): New.
1245 * symbols.h (scm_take_locale_symbol): New.
1246 (scm_take_locale_symboln): New.
1248 2006-01-18 Han-Wen Nienhuys <hanwen@xs4all.nl>
1250 * gc-card.c ("sweep_card"): don't count scm_tc_free_cell for
1253 2005-11-29 Han-Wen Nienhuys <hanwen@xs4all.nl>
1255 * regex-posix.c (s_scm_regexp_exec): list the offending pattern
1258 2005-12-29 Neil Jerram <neil@ossau.uklinux.net>
1260 * fluids.c (next_fluid_num): [From Ludovic Courtès:] Don't trigger
1261 the GC when allocated_fluids_len is zero.
1263 2005-12-14 Neil Jerram <neil@ossau.uklinux.net>
1265 * load.c (the_reader, the_reader_fluid_num): New.
1266 (scm_primitive_load): Support custom reader.
1267 (scm_init_load): Init the_reader and the_reader_fluid_num; export
1268 the_reader as `current-reader'.
1270 * scmsigs.c (do_read_without_guile): Use the "raw_data" passed in
1271 (rather than an uninitialized pointer on the stack).
1273 2005-12-07 Marius Vollmer <mvo@zagadka.de>
1275 Reported by Bruce Korb:
1277 * init.c (invoke_main_func): Don't call exit here. Throws that
1278 are only caught by scm_with_guile will bypass us and would cause
1279 scm_boot_guile to return erroneously.
1280 (scm_boot_guile): Expect scm_with_guile to return and call exit
1281 here, passing it an appropriate exit code.
1285 * script.c (scm_find_executable): Compile fix -- fgetc returns an
1286 unsigned char cast to an int, or -1 for EOS.
1288 2005-12-06 Marius Vollmer <mvo@zagadka.de>
1290 * srfi-4.h, srfi-4.c, srfi-4.i.c (take_uvec): Make BASE pointer
1292 (scm_take_u8vector, etc): Likewise. Thanks to Ludovic Courtès!
1294 * threads.h, threads.c (scm_t_guile_ticket, scm_leave_guile,
1295 scm_enter_guile): Removed from public API. See comment at
1296 scm_without_guile for the rationale.
1298 * scmsigs.c (read_without_guile): New.
1299 (signal_delivery_thread): Use it instead of
1300 scm_leave_guile/read/scm_enter_guile.
1302 From Stephen Compall:
1304 * eval.c (scm_m_cond): Recognize SRFI 61 cond syntax.
1305 (CEVAL): Evaluate SRFI 61 cond clauses.
1307 2005-12-06 Ludovic Courtès <ludovic.courtes@laas.fr>
1309 * gc-card.c (scm_i_card_statistics): Return if BITVEC is NULL.
1310 This was typically hit when running `gc-live-object-stats' right
1311 after starting Guile.
1313 2005-11-30 Kevin Ryde <user42@zip.com.au>
1315 * srfi-13.c (scm_string_append_shared): No copying if just one
1316 non-empty string in args.
1318 2005-11-26 Kevin Ryde <user42@zip.com.au>

1323 * list.c (list): Should be "primitive" in SCM_SNARF_DOCS, not
1326 * random.c (scm_i_copy_rstate, scm_c_make_rstate): Don't test for
1327 scm_malloc returning NULL, it never does that.
1328 * putenv.c (putenv): Likewise.
1330 * socket.c (scm_fill_sockaddr): Remove SCM_C_INLINE_KEYWORD, this is
1331 much too big to want to inline.
1333 2005-11-17 Ludovic Courtès <ludovic.courtes@laas.fr>
1335 * print.c (EXIT_NESTED_DATA): Before popping from the stack, reset
1336 the value at its top. This fixes a reference leak.
1337 (PUSH_REF): Perform `pstate->top++' after calling
1338 `PSTATE_STACK_SET ()' in order to avoid undesired potential side
1341 2005-11-12 Ludovic Courtès <ludovic.courtes@laas.fr>
1343 * gc.c (scm_weak_vectors): Removed.
1345 2005-11-12 Kevin Ryde <user42@zip.com.au>
1347 * socket.c (scm_setsockopt): Missing @defvar in docstring. Reported
1350 2005-11-07 Marius Vollmer <mvo@zagadka.de>
1352 * stime.c (scm_mktime): Use scm_frame_critical_section instead of
1353 SCM_CRITICAL_SECTION_START/END since the code inside the critical
1354 section might exit non-locally.
1356 2005-11-04 Neil Jerram <neil@ossau.uklinux.net>
1358 * eval.c (sym_instead): New symbol.
1359 (ENTER_APPLY): Remove optional use of a continuation when making
1361 (scm_debug_opts): Change doc for 'cheap option to make clear that
1363 (CEVAL, SCM_APPLY): Remove optional use of a continuation when
1364 making trap calls, and implement substitution of eval expressions
1365 and return values using the values that the trap call handlers
1368 * debug.h (SCM_CHEAPTRAPS_P): Removed.
1370 2005-10-27 Ludovic Courtès <ludovic.courtes@laas.fr>

1373 (scm_connect, scm_bind, scm_sendto): Accept sockaddr object.
1374 (scm_addr_vector): Renamed to _scm_from_sockaddr, update usages.
1375 (scm_from_sockaddr, scm_to_sockaddr, scm_make_socket_address,
1376 scm_c_make_socket_address): New functions.
1377 * socket.h: Add prototypes.
1379 2005-10-24 Kevin Ryde <user42@zip.com.au>
1381 * socket.c (scm_init_socket): Add IPPROTO_IP, IPPROTO_TCP,
1382 IPPROTO_UDP. Remove SOL_IP, SOL_TCP, SOL_UDP. The former are in
1383 POSIX spec examples, the latter are not available on for instance
1386 * socket.c (scm_getsockopt, scm_setsockopt): Update docstrings from
1389 * stime.c (scm_strftime): Update docstring from posix.texi.
1391 2005-10-23 Marius Vollmer <marius.vollmer@uni-dortmund.de>

1407 scm_i_pthread_mutexattr_recursive.
1409 2005-09-05 Marius Vollmer <mvo@zagadka.de>
1411 * print.h (SCM_PRINT_KEYWORD_STYLE_I, SCM_PRINT_KEYWORD_STYLE):
1414 (scm_print_opts): Added "quote-keywordish-symbols" option.

1439 scm_string_map_x, scm_string_for_each, scm_string_for_each_index,
1440 scm_string_filter, scm_string_delete): Use scm_t_trampoline_1 for
1441 procedures called in loops.
1443 2005-08-02 Kevin Ryde <user42@zip.com.au>
1445 * strports.c (st_flush): Increase buffer by 1.5x when growing, to
1446 avoid lots of copying where previoulsy growing by only 80 bytes at a
1449 2005-08-01 Marius Vollmer <mvo@zagadka.de>
1451 * modules.h, modules.c (scm_eval_closure_module): Removed, we
1452 already have scm_lookup_closure_module, which does the same thing.
1454 2005-08-01 Marius Vollmer <mvo@zagadka.de>
1456 New marking algorithm for weak hashtables that fixes the problem
1457 that references from the non-weak value to the associated weak
1458 key (for example) would prevent the entry from ever being dropped.
1460 Guardians have been changed back to their original semantics and
1461 are no longer greedy and no longer drop cycles.
1463 * gc-mark.c (scm_mark_all): Do not rely on hooks to run the weak
1464 hashtable and guardian machinery but call the relevant functions
1467 * guardians.h, guardians.c, deprecated.h,
1468 deprecated.c (scm_destroy_guardian_x, scm_guardian_greedy_p,
1469 scm_guardian_destroyed_p, scm_guard, scm_get_one_zombie):
1470 Deprecated and moved into deprecated.[ch].

1493 (scan_weak_hashtables, scm_i_scan_weak_hashtables): Renamed former
1494 to latter. Do not scan the alists themselves, this is done by the
1495 weak vector code now. Just update the element count.
1497 * vectors.h (SCM_I_WVECT_TYPE, SCM_I_WVECT_EXTRA): Renamed former
1498 to latter. The type is now only part of the cell word.
1499 (SCM_I_SET_WVECT_TYPE, SCM_I_SET_WVECT_EXTRA): Likewise.
1501 * init.c (scm_i_init_guile): Do not call scm_weaks_prehistory.
1503 2005-07-18 Mikael Djurfeldt <mdj@d14n36.pdc.kth.se>
1505 Some changes towards making it possible to run Guile on the EM64T
1508 * gc.c (scm_gc_stats): Bugfix: Measure size of the type we are
1509 mallocating for (unsigned long *bounds).
1511 * hashtab.c (scm_i_rehash): Cast SCM_HASHTABLE_FLAGS (table) to
1512 scm_t_bits before storing them in the type word.
1514 * gc.c (tag_table_to_type_alist): Modified type of c_tag from
1517 2005-07-12 Kevin Ryde <user42@zip.com.au>
1519 * eval.c (scm_dbg_make_iloc): Should be SCM_IFRAMEMAX and
1520 SCM_IDISTMAX, and cast uints through scm_t_bits to make gcc happy.
1521 * pairs.c (scm_error_pair_access): Use scm_from_locale_string rather
1522 than scm_makfrom0str.
1523 Reported by Ken Raeburn.
1525 * gc-card.c (scm_dbg_gc_get_bvec): Change return from long* to
1526 scm_t_c_bvec_long*, gcc 4 doesn't like different pointer targets when
1527 returning SCM_GC_CARD_BVEC.
1529 * pairs.c (scm_error_pair_access): Plain ascii ' in error message
1530 rather than latin-1 acute accent, the latter may not print on all
1533 * srfi-13.c (scm_string_filter, scm_string_delete): Strip leading and
1534 trailing deletions, so as to return a substring if those are the only
1537 2005-07-10 Kevin Ryde <user42@zip.com.au>
1539 * socket.c (scm_inet_pton, scm_inet_ntop): Pointer cast to scm_t_uint8
1540 for scm ipv6 funcs, gcc 4 is picky about char* vs uchar*.
1541 (scm_getsockopt, scm_accept, scm_getsockname, scm_getpeername,
1542 scm_recvfrom) Use socklen_t, gcc 4 is picky about int* vs socklen_t*.
1544 2005-07-01 Han-Wen Nienhuys <hanwen@xs4all.nl>
1546 * gc-card.c (scm_i_card_statistics): init tag.
1548 * gc.c (tag_table_to_type_alist): check type of tag. Should be integer.
1550 2005-06-18 Han-Wen Nienhuys <hanwen@xs4all.nl>
1552 * fports.c (s_scm_open_file): add the b flag for binary to the doc
1555 2005-06-25 Kevin Ryde <user42@zip.com.au>
1557 * srfi-13.c (scm_string_filter, scm_string_delete): Partial revert
1558 last change, use plain copy-on-write substrings, the individual
1559 descriptions in the srfi don't mention shared storage (only the
1562 * strings.c (scm_take_locale_stringn): Use realloc to make room for
1563 null-terminator, rather than mallocing a whole new block.
1564 (scm_take_locale_string): Use scm_take_locale_stringn len==-1.
1566 2005-06-12 Marius Vollmer <mvo@zagadka.de>
1568 * ramap.c (scm_array_index_map_x): First test for real arrays,
1569 then check for generalized vectors. This ensures that the
1570 generalized vector case need only work with zero-origin ranges.
1571 (scm_ra_eqp, scm_ra_compare): Use the new array handle functions
1572 to access the target array, making these functions work with all
1573 kinds of arrays, not just bit arrays.
1575 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
1576 gh_list.c, gh_predicates.c: Deprecated everything.
1578 * environments.c (environment_default_folder,
1579 environment_default_observer): Do not use gh_call3, gh_call1.
1581 2005-06-10 Han-Wen Nienhuys <hanwen@xs4all.nl>
1583 * modules.c (s_scm_eval_closure_module): new function. Return the
1584 module inside an eval-closure.
1586 * gc.c (scm_init_storage): make scm_stand_in_procs a weak_key hash
1587 table. This means that procedure properties are GC'd if the
1590 2005-06-11 Kevin Ryde <user42@zip.com.au>
1592 * srfi-13.c (scm_string_filter, scm_string_delete): For char and
1593 charset cases, count chars kept and build a string in a second pass,
1594 rather than using a cons cell for every char kept. Use a shared
1595 substring when nothing removed (such sharing is allowed by the srfi).
1597 2005-06-09 Han-Wen Nienhuys <hanwen@xs4all.nl>
1599 * gc.c (tag_table_to_type_alist): convert tag number to "tag %d"
1600 string, so live object stats can be sorted with string<?.
1602 2005-06-06 Marius Vollmer <mvo@zagadka.de>
1604 * print.c (iprin1): When writing a string, collect all characters
1605 that can be printed directly into one call to scm_lfwrite.
1606 Previously, every character was output with its own call to
1607 write(2) on unbuffered ports.
1609 * eval.c (scm_eval_options_interface): Use
1610 scm_frame_critical_section instead of SCM_CRITICAL_SECTION_START
1611 and SCM_CRITICAL_SECTION_END.
1613 * unif.c (scm_array_in_bounds_p): First test for real arrays, then
1614 check for generalized vectors. This ensures that the generalized
1615 vector case need only work with zero-origin ranges.
1617 2005-06-06 Kevin Ryde <user42@zip.com.au>
1619 * srfi-13.c (scm_string_split): Compare char/char in scan. Mixing an
1620 unsigned int SCM_CHAR and a char string meant an 8-bit char was never
1623 2005-06-05 Marius Vollmer <mvo@zagadka.de>
1625 * eval.c: Added comment on how to make case 1.1 of
1626 r5rs_pitfall.test succeed.
1628 From Jan Nieuwenhuizen <janneke@gnu.org>. Thanks!
1630 * hashtab.h: Bugfix: use SCM_API (WAS: extern).
1632 * socket.c: Remove obsolete comment about socklen_t.
1633 (s_scm_setsockopt)[!HAVE_IP_MREQ]: Do not use ip_mreq code.
1635 * numbers.h (isnan)[__MINGW32__]: Remove.
1637 * Makefile.am (gen_scmconfig_SOURCES): Bugfix: Add
1638 DEFAULT_INCLUDES when cross compiling.
1640 * threads.c (ETIMEDOUT, pipe)[__MINGW32__]: Add defines.
1642 * stime.c (scm_strftime)[!HAVE_TM_ZONE]: Use
1643 SCM_SIMPLE_VECTOR_REF instead of SCM_VELTS. (Changed slightly
1646 2005-05-22 Marius Vollmer <mvo@zagadka.de>
1648 * unif.c (scm_make_shared_array): Add old base to new base since
1649 scm_array_handle_pos does not include the base.
1650 (scm_aind): Likewise.
1652 * ports.c (scm_putc, scm_puts): Assert that the port argument is a
1655 2005-05-12 Neil Jerram <neil@ossau.uklinux.net>
1657 Mac OS X compile warning fixes, reported by Richard Todd.
1659 * unif.c (scm_i_read_array): Declare rank as ssize_t, to guarantee
1662 * strports.c (st_resize_port): Add unsigned char cast.
1663 (scm_mkstrport): Make read/write_buf cast unsigned.
1665 * srfi-13.c (string_titlecase_x): Add unsigned char cast.
1667 * rdelim.c (scm_read_line): Initialize slen.
1669 * load.c (scm_search_path): Remove weird >=1, and add
1670 parentheses to clarify conditions.
1672 * hash.c (scm_hasher): Add const unsigned char cast.
1674 * gh_data.c (gh_chars2byvect): Add scm_t_int8 cast.
1676 2005-05-11 Neil Jerram <neil@ossau.uklinux.net>

1680 * threads.c (s_scm_lock_mutex): Don't declare msg in middle of
1683 * gc.c (s_scm_gc_live_object_stats): Don't declare alist in middle
1686 * gc-card.c (scm_i_card_statistics): Don't declare tag in middle
1688 (scm_i_card_statistics): Add block for declarations of tag_as_scm
1691 2005-05-10 Neil Jerram <neil@ossau.uklinux.net>
1693 * scmsigs.c (signal_delivery_thread): Return a value, to avoid
1694 compile warning reported by Werner Scheinast.
1696 2005-04-30 Han-Wen Nienhuys <hanwen@xs4all.nl>
1698 * list.h: remove scm_list()
1700 * fluids.c (DYNAMIC_STATE_NEXT_LOC): new macro for use with
1701 SCM_DEBUG_CELL_ACCESSES
1702 (FLUID_NEXT_LOC): idem.
1704 2005-04-30 Kevin Ryde <user42@zip.com.au>
1706 * numbers.c (scm_divide): Correction to 1/complex and <any>/complex,
1707 need to test abs(re)<abs(im) for choice of cases, otherwise divide by
1708 zero when re==0 and im<0. Reported by Jean Crepeau.
1710 2005-04-25 Kevin Ryde <user42@zip.com.au>
1712 * ramap.c (scm_array_map_x): Allow no source args, add num args checks
1713 to subr_1, subr_2, subr_2o and dsubr cases. No source args only has a
1714 few sensible uses (like filling with a random number generator say),
1715 but has been allowed in the past and so should be kept.
1717 2005-04-23 Kevin Ryde <user42@zip.com.au>
1719 * hashtab.c (scm_hashx_remove_x): Need to pass "closure" to
1720 scm_hash_fn_remove_x.
1722 * list.c (scm_cons_star): Don't modify the rest list, it belongs to
1723 the caller when cons* is reached through apply.
1725 * list.c (list): Use scm_list_copy, so as to produce a fresh list when
1726 list is called using apply, under the debugging evaluator.
1729 * list.c, list.h (scm_make_list): New code, moving make-list from
1732 2005-04-14 Kevin Ryde <user42@zip.com.au>
1734 * numbers.c, numbers.h (scm_oneplus, scm_oneminus): New functions,
1735 converted from scheme code in boot-9.scm.
1737 2005-04-11 Kevin Ryde <user42@zip.com.au>
1739 * srfi-13.c (scm_string_concatenate, scm_string_concatenate_shared):
1740 Validate list argument, scm_string_append and scm_string_append_shared
1741 don't do that to their rest argument (in a normal build).
1743 2005-04-04 Marius Vollmer <marius.vollmer@uni-dortmund.de>
1745 * hashtab.h, hashtab.c (scm_t_hashtable): Removed 'closure' field. The
1746 closure can not be stored since it is no longer valid at GC time.
1747 (make_hash_table): Initialize 'hash_fn' field.
1748 (scm_i_rehash): Only store hash_fn in hash table when closre is
1750 (rehash_after_gc): Only call scm_i_rehash when 'hash_fn' is
1751 non-NULL. Always use a NULL closure.
1752 (scm_hash_fn_create_handle_x): Also rehash when table contains too
1755 2005-03-29 Marius Vollmer <marius.vollmer@uni-dortmund.de>
1757 * hashtab.h, hashtab.c (scm_hash_fx_remove_x): Removed delete_fn
1758 argument; always use scm_delq_x. The delete_fn function works on
1759 the handle, not the key, and it therefore makes no sense to make
1760 it configurable. Changed all callers.
1761 (scm_hashx_remove_x): Likewise. Also, exported to Scheme.
1762 (scm_hash_clear): Accept plain vectors as hashtables.
1763 (scm_delx_x): Removed.
1765 2005-03-28 Han-Wen Nienhuys <hanwen@xs4all.nl>
1767 * inline.h (scm_double_cell): use __asm__ iso. asm, to maintain
1768 compatibility with gcc -std=c99.
1770 2005-03-24 Mikael Djurfeldt <djurfeldt@nada.kth.se>
1772 * async.h (scm_mask_ints): Removed left over reference to
1775 * threads.c: Removed fprintf debug statements.
1777 2005-03-24 Neil Jerram <neil@ossau.uklinux.net>
1779 * debug.c (scm_make_memoized): Restore use of SCM_UNPACK.
1781 2005-03-23 Neil Jerram <neil@ossau.uklinux.net>
1783 * debug.c (scm_make_memoized): Remove unnecessary critical
1784 section, and simplify by using SCM_RETURN_NEWSMOB.
1786 2005-03-20 Mikael Djurfeldt <djurfeldt@nada.kth.se>
1788 * strings.h (SCM_STRING_UCHARS): Added missing argument.
1790 2005-03-18 Kevin Ryde <user42@zip.com.au>
1792 * arbiters.c (FETCH_STORE) [generic C]: Should be
1793 scm_i_scm_pthread_mutex_lock/unlock now. Reported by Ludovic Courtès.
1795 2005-03-13 Kevin Ryde <user42@zip.com.au>
1797 * numbers.c, numbers.h (scm_i_clonebig): Remove static, so can use in
1800 * numbers.c (scm_logior): Must scm_i_normbig results as per scm_logand,
1801 because OR-ing bits into a negative can reduce the value to an inum.
1803 * numbers.c (scm_num_eq_p): On 64-bit systems, be careful about
1804 casting inum to double since that can lose precision.
1806 2005-03-10 Marius Vollmer <marius.vollmer@uni-dortmund.de>
1808 * threads.h, threads.c (scm_i_thread): Added gc_running_p field.
1809 (guilify_self_1): Initialize it.
1811 * gc.h, gc.c (SCM_FREECELL_P): Removed for good.
1812 (scm_block_gc, scm_gc_heap_lock): Removed. Removed all uses.
1813 (scm_gc_running_p): Now a macro that refers to the scm_i_thread
1815 (scm_i_sweep_mutex): Now a non-recursive mutex. GC can not happen
1817 (scm_igc, scm_i_gc): Renamed former to latter. Changed all uses.
1818 Do not lock scm_i_sweep_mutex, which is now non-recursive, or set
1819 scm_gc_running_p. Do not run the scm_after_gc_c_hook.
1820 (scm_gc): Lock scm_i_sweep_mutex, set scm_gc_running_p and run the
1821 scm_after_gc_c_hook here.
1822 (scm_gc_for_new_cell): Set scm_gc_running_p here and run the
1823 scm_after_gc_c_hook when a full GC has in fact been performed.
1824 (scm_i_expensive_validation_check): Call scm_gc, not scm_i_gc.
1826 * gc-segment.c (scm_i_get_new_heap_segment): Do not check
1829 * gc-malloc.c (scm_realloc, increase_mtrigger): Set
1830 scm_gc_running_p while the scm_i_sweep_mutex is locked.
1832 * inline.h (scm_cell, scm_double_cell): Do not check
1833 scm_gc_running_p, allocation during sweeping is OK.
1835 * gdbint.c (SCM_BEGIN_FOREIGN_BLOCK, SCM_END_FOREIGN_BLOCK): Do
1836 not set scm_block_gc.
1838 * init.c (scm_i_init_guile): Do not set scm_block_gc.
1840 * deprecation.c (scm_c_issue_deprecation_warning): Use malloc
1841 instead of scm_malloc. The latter can not be used during GC.
1843 2005-03-09 Marius Vollmer <mvo@zagadka.de>
1845 * script.c (scm_compile_shell_switches): Added 2005 to Copyright
1848 2005-03-09 Marius Vollmer <marius.vollmer@uni-dortmund.de>
1850 * gc-card.c (scm_i_sweep_card): Do not increase/decrease
1851 scm_gc_running_p. Sweeping can happen in parallel with
1854 * inline.h: Updated comments for current threading implementation.
1856 * threads.h, threads.c (scm_i_frame_single_threaded): Removed.
1857 (scm_i_thread): Removed unused signal_asyncs field.
1858 (threads_mark): Do not mark it.
1859 (guilify_self_1): Do not initialize it. Do initialize
1860 continuation_root field.
1861 (do_thread_exit): Do not remove thread from all_threads list.
1862 (on_thread_exit): Do it here, after leaving guile mode.
1863 (sleep_level): Removed.
1864 (scm_i_thread_put_to_sleep): Leave thread_admin_mutex locked when
1865 returning. Do not support recursive sleeps.
1866 (scm_i_thread_wake_up): Expect thread_admin_mutex to be locked on
1867 entry. Do not support recursive sleeps.
1869 * fluids.c (ensure_state_size, ensure_all_state_sizes,
1870 resize_all_states): Collapsed ensure_state_size and
1871 ensure_all_state_sizes into one function named resize_all_states.
1872 Allocate new vectors outside of single threaded region. Do only
1873 simple things inside that region.
1874 (scm_make_fluid, scm_make_dynamic_state): Lock fluid_admin_mutex
1875 while adding to the global lists.
1878 2005-03-08 Marius Vollmer <mvo@zagadka.de>
1880 libltdl is no longer distributed. We expect it to be installed
1883 * Makefile.am (INCLUDES): Removed @LTDLINCL@.
1884 (libguile_la_LIBADD): Removed @LIBLTDL@.
1886 2005-03-07 Marius Vollmer <mvo@zagadka.de>
1888 * threads.h, async.h, threads.c (SCM_CRITICAL_SECTION_START,
1889 SCM_CRITICAL_SECTION_END): Moved here from threads.h since now
1890 they also block/unblock execution of asyncs and call
1891 scm_async_click which is declared in async.h but threads.h can not
1892 include async.h since async.h already includes threads.h.
1893 (scm_i_critical_section_level): New, for checking mistakes in the
1894 use of the SCM_CRITICAL_SECTION_* macros.
1895 (scm_i_critical_section_mutex): Make it a recursive mutex so that
1896 critical sections can be nested.
1898 * throw.c (scm_ithrow): Abort when scm_i_critical_section_level is
1901 * threads.h, threads.c (scm_frame_lock_mutex): New.

1904 (scm_init_threads): Initialize it.
1905 (scm_threads_prehistory): Do not initialize thread_admin_mutex and
1906 scm_i_critical_section_mutex; both are initialized statically.

1909 libguile_la-arrays.loT, objprop.c, ports.c, smob.c, sort.s,
1910 srcprop.c, stime.c, struct.c, throw.c, regex-posix.c: Include
1911 "libguile/async.h" for SCM_CRITICAL_SECTION_START/END.
1913 * debug.c (scm_debug_options): Replace
1914 SCM_CRITICAL_SECTION_START/END with a frame and
1915 scm_frame_critical_section.
1917 * continuations.c (scm_make_continuation): No longer a critical
1919 (scm_dynthrow): Abort when scm_i_critical_section_level is
1922 2005-03-04 Marius Vollmer <marius.vollmer@uni-dortmund.de>

1932 Big merge from the mvo-thread-cleanup branch. The main changes
1935 - The dynamic roots functionality has been split into dynamic
1936 states and continuations barriers. Fluids have been
1937 reimplemented and can now be garbage collected.
1939 - Initialization of Guile now works in a multi-thread friendly
1940 manner. Threads can freely enter and leave guile mode.
1942 - Blocking on mutexes or condition variables or while selecting
1943 can now be reliably interrupted via system asyncs.
1945 - The low-level threading interface has been removed.

2783 Enclosed arrays are now their own smob. This has been done to
2784 make the code more explicit about them and to prepare for the time
2785 when generalized vectors include arbitrary one-dimensional
2786 arrays. (Uptonow, enclosed arrays have been recognized by their

2833 * ramap.c (cind): Changed second arg to be pointer to long instead
2835 (scm_ramapc): Allocate index vector with scm_malloc and not as
2836 uniform vector. Wrap it in a frame so that it gets properly freed.
2837 (scm_array_index_map_x): Likewise.
2839 * unif.c: Changed all uses of scm_array_prototype to

3056 First cut at integrating uniform vectors from srfi-4 with the rest
3057 of Guile. This change replaces scm_tc7_byvect with a s8 uniform

3386 just on a line of its own.
3388 * srfi-13.c (scm_string_any, scm_string_every,
3389 scm_string_tabulate, string_upcase_x, string_down_case_x,
3390 string_titlecase_x, string_reverse_x, scm_string_tokenize): Use

3410 2004-09-09 Kevin Ryde <user42@zip.com.au>
3412 * filesys.c, stime.c (_POSIX_C_SOURCE): Use this only on hpux, it

3457 2004-09-03 Stefan Jahn <stefan@lkcc.org>
3459 * threads.c (scm_threads_mark_stacks): Fixed local variable

3504 scm_i_string_chars et al. Copious scm_remember_upto_heres have
3505 been inserted. Made sure that no internal string pointer is used
3506 across a SCM_TICK or a possible GC.
3508 * script.c (scm_compile_shell_switches): Use
3509 scm_from_locale_string instead of scm_makfrom0str.
3511 * srfi-13.c (scm_string_rindex): Export to Scheme, as it has

3533 scm_string_geq_p, scm_string_ci_less_p, scm_string_ci_leq_p,
3534 scm_string_ci_gr_p, scm_string_ci_geq_p): Use scm_string_eq, etc
3535 instead of explicit code.
3537 * deprecated.c, load.c, posix.c, unif.c, symbols.c: Include

3570 * eval.c (scm_lookupcar1): Report "Variable used before given a
3571 value" insetad of an "Unbound" one for variables that are found
3572 but still contain SCM_UNDEFINED.
3574 * posix.c (scm_mkstemp): Correction to the correction, mkstemp
3575 expects a null-terminated string in the locale encoding, but
3576 scm_i_string_writable_chars doesn't give that. Fixed by letting
3577 mkstemp modify a locale version of the tmpl argument and copying
3578 the result back into tmpl.

3829 * read.c (scm_input_error): Use a SCM value for 'fn', not a C
3830 string. This avoids a conversion round-trip.
3832 * gh_data.c: Replaced SCM_STRINGP, SCM_STRING_CHARS, and
3833 SCM_STRING_LENGTH with SCM_I_STRINGP, SCM_I_STRING_CHARS, and
3834 SCM_I_STRING_LENGTH, respectively.
3835 (gh_scm2newstr): Implement in terms of scm_to_locale_string.
3837 * environments.c: Instead calling scm_puts on the SCM_STRING_CHARS
3838 of a string, call scm_display on the string itself.
3840 * dynwind.c, dynwind.h (scm_frame_free): New.
3842 * stime.c, socket.c, simpos.c, procs.c, posix.c, ports.c,
3843 net_db.c, fports.c, filesys.c, eval.c, deprecation.c, dynl.c:
3844 Replaced uses of SCM_STRING_CHARS with proper uses of
3845 scm_to_locale_string. Replaced SCM_STRINGP with scm_is_string.
3846 Replaced scm_mem2string with scm_from_locale_string.
3848 * simpos.c, posix.c (allocate_string_pointers, environ_list_to_c):
3849 Removed, replaced all uses with scm_i_allocate_string_pointers.
3851 * load.h, load.c (scm_internal_parse_path): Removed.
3852 (scm_parse_path): Use scm_string_split to do the work.
3853 (scm_init_load_path): Use scm_parse_path instead of
3854 scm_internal_parse_path.
3855 (scm_search_path): Rewritten string handling part of the code in
3856 terms of scm_to_locale_stringbuf and so that it is thread safe.
3858 * error.c (scm_error_scm): Throw directly instead of calling
3859 scm_error, this avoids the back and forth conversion of SUBR and
3860 MESSAGE and also plugs a memory leak.
3861 (scm_error): Call scm_error_scm.
3863 * backtrace.c: Replaced SCM_STRINGP with scm_is_string.
3864 (display_header): Print FNAME when it is true, not
3865 merely when it is a string.
3867 * strings.h (SCM_SET_STRING_LENGTH, SCM_SET_STRING_CHARS): Removed
3868 unceremoniously. They were unused by Guile itself, and external
3869 use should stop immediately.
3872 2004-08-10 Marius Vollmer <mvo@zagadka.de>
3874 * numbers.h, number.c, deprecated.h, deprecated.c (scm_round,
3875 scm_truncate): Renamed to scm_c_round and scm_c_truncate;
3876 deprecated versions installed in deprecated.h and deprecated.c.
3879 2004-08-06 Rob Browning <rlb@defaultvalue.org>
3881 * net_db.c (scm_resolv_error): don't cause an exception while
3882 trying to throw an exception -- call scm_misc_error with correct
3883 arguments. The previous arguments needed a format escape that
3884 wasn't in any of the format strings.
3886 2004-08-06 Kevin Ryde <user42@zip.com.au>
3888 * ramap.c (scm_array_fill_x): For byvect char fill, force signed char
3889 so as not to depend on signedness of plain char. For byvect range
3890 check, throw out-of-range rather than wrong-type-arg.
3892 * unif.c (scm_uniform_vector_ref, scm_array_set_x): For byvect, force
3893 signed byte range checks by using scm_to_schar and scm_from_schar,
3894 don't want to depend on signedness of C char.
3896 2004-08-05 Kevin Ryde <user42@zip.com.au>
3898 * arbiters.c (scm_try_arbiter): Use scm_i_misc_mutex instead of
3900 (scm_release_arbiter): Use scm_i_misc_mutex so return value can be
3901 guaranteed if multiple threads compete to unlock.
3902 Update docstrings per doc/ref/api-scheduling.texi.
3904 * filesys.c (scm_copy_file): Use fstat on the input fd rather than
3905 stat on the filename, to be certain a file rename can't mean we get
3906 info on one filesystem object but open another. This fstat usage is
3907 similar to Emacs copy-file.
3909 * posix.c (scm_setgroups): Enhance docstring, per doc/ref/posix.texi.
3911 * simpos.c (scm_system_star): Change scm_from_long to scm_from_int on
3912 SIGINT and SIGQUIT, since those values are ints.
3914 2004-08-03 Marius Vollmer <marius.vollmer@uni-dortmund.de>
3916 * num2integral.i.c, num2float.i.c: Removed.
3917 * Makefile.am (noinst_HEADERS): Updated.

3922 (scm_number_p): Export as "number?" to Scheme.
3923 (scm_is_complex, scm_is_number): New.
3924 (scm_c_make_rectangular, scm_c_make_polar): New.

3928 (scm_make_complex): Discouraged by moving to discouraged.h and
3929 discouraged.c. Replaced all uses with scm_c_make_rectangular.

3932 (scm_is_rational): New.
3933 (scm_i_short2big, scm_i_int2big, scm_i_uint2big, scm_i_size2big,
3934 scm_i_ptrdiff2big, scm_i_long_long2big, scm_i_ulong_long2big):
3936 (scm_make_real, scm_num2dbl, scm_float2num, scm_double2num):
3937 Discouraged by moving to discouraged.h and discouraged.c.
3938 Replaced all uses with scm_from_double.
3939 (scm_num2float, scm_num2double): Discouraged by moving prototype
3940 to discouraged.h and rewriting in terms of scm_to_double.
3941 Replaced all uses with scm_to_double.
3942 (scm_to_double): Do not implement in terms of scm_num2dbl, use
3944 (scm_from_double): Do not implement in terms of scm_make_real, use
3947 2004-08-02 Marius Vollmer <marius.vollmer@uni-dortmund.de>

3954 * eval.c (SCM_EVALIM, SCM_EVALIM2, SCM_XEVAL, SCM_XEVALCAR):
3955 Renamed to SCM_I_* in order to avoid collisions with the versions
3956 defined in deprecated.h.
3958 * discouraged.h, discouraged.c: New files.
3960 * deprecated.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOLP, SCM_EQ_P,

3969 scm_long_long2num, scm_ulong_long2num, scm_num2long_long,
3970 scm_num2ulong_long): Discouraged by moving to discouraged.h and
3971 discouraged.c and reimplementing in terms of scm_from_* and
3972 scm_to_*. Changed all uses to the new scm_from_* and scm_to_*
3975 * numbers.h, numbers.c: Removed GUILE_DEBUG code.
3976 (scm_i_short2big, scm_i_ushort2big, scm_i_int2big, scm_i_uint2big,
3977 scm_i_size2big, scm_i_ptrdiff2big): Removed.
3978 (scm_i_long2big, scm_i_ulong2big): New, explicit definitions.
3979 * conv-integer.i.c, conv-uinteger.i.c: Use them instead of
3982 2004-08-02 Kevin Ryde <user42@zip.com.au>
3984 * __scm.h (SCM_DEFER_INTS, SCM_ALLOW_INTS): Add comments about past
3985 and current usage and migration.
3987 2004-07-31 Kevin Ryde <user42@zip.com.au>
3989 * error.c (scm_strerror): Use scm_i_misc_mutex around strerror since
3990 it's not thread safe.
3991 (scm_syserror): Use scm_strerror rather than SCM_I_STRERROR, to take
3993 * fports.c (scm_open_file): Use scm_strerror likewise.
3994 * filesys.c (scm_stat, scm_lstat): Ditto.
3996 * filesys.c (scm_copy_file): Avoid fd leak when destination file
3999 * symbols.c (scm_gensym): Use scm_i_misc_mutex around gensym_counter
4000 update, for thread safety.
4001 (gensym_counter): Move into scm_gensym which is its only user.

4012 scm_from_long_long, scm_from_ulong_long, scm_from_intmax,
4013 scm_from_uintmax, scm_from_size_t, scm_from_ssize_t): No longer
4014 defined in terms of scm_to_signed_integer, etc, but in terms of
4017 * gen-scmconfig.c (SCM_SIZEOF_INTMAX, SCM_SIZEOF_SIZE_T): New.
4019 * gen-scmconfig.h.in: Removed SCM_I_GSC_*_LIMITS macros, they are
4022 * __scm.h (SCM_I_UTYPE_MAX, SCM_I_TYPE_MAX, SCM_I_TYPE_MIN,
4023 SCM_I_SIZE_MAX, SCM_I_SSIZE_MIN, SCM_I_SSIZE_MAX): New.

4030 SCM_T_INTMAX_MIN, SCM_T_INTMAX_MAX, SCM_T_UINTMAX_MAX): Moved
4031 definition into __scm.h, using new SCM_I_TYPE_MIN, etc.

4034 the functions below.
4036 * Makefile.am (noinst_HEADERS): Added conv-integer.i.c and

4042 scm_from_uint16, scm_from_int32, scm_from_uint32, scm_from_int64,
4043 scm_from_uint64): Turned from macros into proper functions.
4044 (scm_to_signed_integer, scm_to_unsigned_integer,
4045 scm_from_signed_integer, scm_from_unsigned_integer): Generate via
4046 conv-integer.i.c and conv-uinteger.i.c, as well.
4048 * number.h (scm_to_ssize_t, scm_to_size_t): Use the new
4049 SCM_I_SSIZE_MIN, SCM_I_SSIZE_MAX, and SCM_I_SIZE_MAX macros for
4050 the limits. Those are always defined.
4052 2004-07-29 Kevin Ryde <user42@zip.com.au>
4054 * posix.c (scm_ttyname): Use scm_i_misc_mutex for thread safety.
4056 2004-07-28 Kevin Ryde <user42@zip.com.au>
4058 * posix.c (scm_ctermid): Use an L_ctermid buf on the stack, for thread
4061 * unif.c (scm_array_set_x): For svect, use scm_num2short for
4062 consistency with other vector types and to get arg and func name into

4067 * deprecated.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOLP, SCM_BOOL):
4068 Reimplement using scm_is_false, scm_is_true, scm_is_bool, and
4069 scm_from_bool, respectively.
4070 (SCM_NINUMP): Added.
4072 * tags.h, deprecated.h (SCM_EQ_P): Deprecated by moving it into
4073 deprecated.h. Replaced all uses with scm_is_eq.
4075 2004-07-24 Kevin Ryde <user42@zip.com.au>
4077 * threads.c, threads.h (scm_i_misc_mutex): New SCM_GLOBAL_MUTEX.
4078 * posix.c (scm_crypt): Use it to protect static data in crypt().
4080 2004-07-23 Marius Vollmer <marius.vollmer@uni-dortmund.de>
4082 * deprecated.h, deprecated.c, numbers.h (SCM_INUMP, SCM_NINUMP,
4083 SCM_INUM): Deprecated by renaming them to SCM_I_INUMP,
4084 SCM_I_NINUMP and SCM_I_INUM, respectively and adding deprecated
4085 versions to deprecated.h and deprecated.c. Changed all uses to
4086 either use the SCM_I_ variants or scm_is_*, scm_to_*, or
4087 scm_from_*, as appropriate.
4089 * dynwind.c (scm_i_dowinds): Removed unused code that would call
4090 the unexisting scm_cross_dynwind_binding_scope for inums on the
4093 2004-07-10 Marius Vollmer <marius.vollmer@uni-dortmund.de>
4095 * socket.c (ipv6_net_to_num, scm_from_ipv6): Renamed
4096 ipv6_net_to_num to scm_from_ipv6, for converting from an IPv6
4097 byte-wise address to a SCM integer. Changed all uses.
4098 (ipv6_num_to_net, scm_to_ipv6): Renamed ipv6_num_to_net to
4099 scm_to_ipv6 and added type and range checking, for converting from
4100 an IPv& byte-wise address to a SCM integer. Changed all uses.
4101 (bignum_in_ipv6_range_p, VALIDATE_INET6): Removed, their function
4102 is now done by scm_to_ipv6.
4104 * numbers.c (scm_to_signed_integer, scm_to_unsigned_integer): dot
4105 not accept inexact integers.
4107 * validate.h, deprecated.h (SCM_VALIDATE_INUM,
4108 SCM_VALIDATE_INUM_COPY, SCM_VALIDATE_BIGINT,
4109 SCM_VALIDATE_INUM_MIN, SCM_VALIDATE_INUM_MIN_COPY,
4110 SCM_VALIDATE_INUM_MIN_DEF_COPY,SCM_VALIDATE_INUM_DEF,
4111 SCM_VALIDATE_INUM_DEF_COPY, SCM_VALIDATE_INUM_RANGE,
4112 SCM_VALIDATE_INUM_RANGE_COPY): Deprecated because they make the
4113 fixnum/bignum distinction visible. Changed all uses to
4114 scm_to_size_t or similar.
4116 2004-07-09 Marius Vollmer <marius.vollmer@uni-dortmund.de>
4118 * cpp_cnvt.awk: Use scm_from_int instead of SCM_MAKINUM.
4120 2004-07-10 Kevin Ryde <user42@zip.com.au>
4122 * hash.c (scm_hashq, scm_hashv, scm_hash): Restrict to size>=1 rather
4123 than size>=0, since 0<=hash<size cannot be satisfied for size==0, and
4124 such a size causes divide-by-zeros in scm_hasher.
4126 * regex-posix.c (scm_make_regexp): Free rx on error, to avoid memory
4129 2004-07-08 Marius Vollmer <marius.vollmer@uni-dortmund.de>
4131 * numbers.c (scm_is_signed_integer, scm_is_unsigned_integer):
4132 Rewritten using the same logic as scm_to_signed_integer and
4133 scm_to_unsigned_integer, respectively, which is better(tm). Also,
4134 use CHAR_BIT instead of hardcoding 8.
4135 (LLONG_MIN, LLONG_MAX, ULLONG_MAX): Removed and used
4136 SCM_I_LLONG_MIN etc. instead.
4138 * numbers.h (SCM_MAKINUM, SCM_I_MAKINUM): Renamed SCM_MAKINUM to
4139 SCM_I_MAKINUM and changed all uses.
4140 * deprecated.h, deprecated.c (SCM_MAKINUM): Newly deprecated.
4142 * gen-scmconfig.c (SCM_I_LLONG_MIN, SCM_I_LLONG_MAX,
4143 SCM_I_ULLONG_MAX): Instead of hard-coding the numbers, compute
4144 them by assuming twos-complement.
4146 2004-07-07 Marius Vollmer <marius.vollmer@uni-dortmund.de>
4148 * gen-scmconfig.h.in: Added all the new SCM_I_GSC_*_LIMITS that
4149 configure now produces.
4150 * gen-scmconfig.c: Use them to output SCM_T_INT8_MIN, etc
4151 definitions, giving the limits of the integer types defined by
4152 Guile. Also, output a hard coded SCM_I_LLONG_MIN, etc since
4153 LLONG_MIN or LONG_LONG_MIN is hard to get at.
4155 * numbers.h (scm_to_short, scm_to_ushort): It's SHRT_MIN, etc, not
4157 (scm_to_size_t): Use SIZE_MAX instead of cooking our own.
4158 (scm_to_long_long, scm_to_ulong_long, scm_to_int8, scm_to_uint8,
4159 scm_to_int16, scm_to_uint16, scm_to_int32, scm_to_uint32,

4163 scm_from_uint32, scm_from_int64, scm_from_uint64, scm_from_intmax,
4164 scm_from_uintmax): New.
4166 2004-07-06 Marius Vollmer <marius.vollmer@uni-dortmund.de>
4168 * tags.h (scm_is_eq): New.
4170 * deprecated.h, boolean.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOL,
4171 SCM_NEGATE_BOOL, SCM_BOOLP): Deprecated by moving into
4172 "deprecated.h". Replaced all uses with scm_is_false, scm_is_true,
4173 scm_from_bool, and scm_is_bool, respectively.
4175 * boolean.h (scm_is_bool): Fix bug in prototype.
4176 (scm_from_bool): The argument is "x" not "f", stupid.
4178 * boolean.c (scm_is_bool): Fix typo.
4180 * numbers.h, numbers.c (scm_is_integer, scm_is_signed_integer,
4181 scm_is_unsigned_integer, scm_to_signed_integer,
4182 scm_to_unsigned_integer, scm_to_schar, scm_to_uchar, scm_to_char,

4195 2004-06-27 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4197 * backtrace.c (display_expression, display_frame): Call
4198 scm_i_unmemoize_expr for unmemoizing a memoized object holding a
4199 single memoized expression.
4201 * debug.c (memoized_print): Don't try to unmemoize the memoized
4202 object, since we can't know whether it holds a single expression
4205 (scm_mem_to_proc): Removed check for lambda expression, since it
4206 was moot anyway. Whoever uses these functions for debugging
4207 purposes should know what they do: Creating invalid memoized code
4208 will cause crashes, independent of whether this check is present
4211 (scm_proc_to_mem): Take the closure's code as it is and don't
4212 append a SCM_IM_LAMBDA isym. To allow easier debugging, the
4213 memoized code should not be modified.
4215 * debug.[ch] (scm_unmemoize, scm_i_unmemoize_expr): Removed
4216 scm_unmemoize from public use, but made scm_i_unmemoize_expr
4217 available as a guile internal function instead. However,
4218 scm_i_unmemoize_expr will only work on memoized objects that hold
4219 a single memoized expression. It won't work with bodies.
4221 * debug.c (scm_procedure_source), macros.c (macro_print), print.c
4222 (scm_iprin1): Call scm_i_unmemocopy_body for unmemoizing a body,
4223 i. e. a list of expressions.
4225 * eval.c (unmemoize_exprs): Drop internal body markers from the
4226 output during unmemoization.
4228 * eval.[ch] (scm_unmemocopy, scm_i_unmemocopy_expr,
4229 scm_i_unmemocopy_body): Removed scm_unmemocopy from public use,
4230 but made scm_i_unmemocopy_expr and scm_i_unmemocopy_body available
4231 as guile internal functions instead. scm_i_unmemoize_expr will
4232 only work on a single memoized expression, while
4233 scm_i_unmemocopy_body will only work on bodies.
4235 2004-06-21 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4237 * eval.c (unmemoize_exprs): Handle semi-memoized code.
4239 (scm_cons_source, scm_primitive_eval): Prefer higher level
4240 predicate SCM_FALSEP over SCM_IMP.
4242 2004-06-15 Rob Browning <rlb@defaultvalue.org>
4244 * script.c (scm_shell_usage): minor phrasing change.
4246 * gc_os_dep.c: update ifdefery for macosx.
4247 (scm_get_stack_base): separate result initialization from
4248 declaration to slience warnings with macosx and hp-ux using gcc
4249 3.3. Thanks to Andreas Vögele.
4251 2004-06-13 Han-Wen Nienhuys <hanwen@xs4all.nl>
4253 * eval.c (unmemoize_exprs): use SCM_CONSP for the loop condition.
4255 2004-06-06 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4257 * list.[ch] (scm_i_finite_list_copy): New internal function to
4258 copy lists that are known to be finite (though not necessarily
4261 * debug.c (scm_procedure_source): Don't have scm_unmemocopy treat
4262 a closure's argument list like an expression of a body.
4264 * eval.c (unmemoize_expression, unmemoize_exprs, unmemoize_and,
4265 unmemoize_begin, unmemoize_case, unmemoize_cond, unmemoize_delay,
4266 unmemoize_do, unmemoize_if, unmemoize_lambda, unmemoize_let,
4267 unmemoize_letrec, unmemoize_letstar, unmemoize_or,
4268 unmemoize_set_x, unmemoize_apply, unmemoize_atcall_cc,
4269 unmemoize_at_call_with_values, unmemoize_future, sym_atslot_ref,
4270 unmemoize_atslot_ref, sym_atslot_set_x, unmemoize_atslot_set_x,
4271 unmemoize_builtin_macro): New static functions and symbols.
4273 (scm_unmemocopy): Rewritten in terms of the above. scm_unmemocopy
4274 now has a slightly different meaning: The memoized form that is
4275 receives as its argument is now interpreted as a sequence of
4276 expressions from a body.
4278 (unmemocar, scm_unmemocar): Since the whole functionality of
4279 unmemocar and scm_unmemocar is not needed any more, scm_unmemocar
4280 has its old content back and is deprecated, while unmemocar has
4283 (SCM_BIT7): Removed.
4285 (CEVAL): For unmemoizing a single expression, call
4286 unmemoize_expression instead of scm_unmemocopy, which now expects
4287 a sequence of body expressions. Eliminated unnecessary empty
4288 environment frame when executing let* forms. Eliminated
4289 unmemoization step from evaluator.
4291 2004-06-02 Marius Vollmer <marius.vollmer@uni-dortmund.de>
4293 * eval.c (scm_macroexp, macroexp): Renamed scm_macroexp to
4294 macroexp and made static. Added new version of scm_macroexp that
4295 emits a deprecation warning and then calls macroexp.
4296 (scm_m_undefine): Issue deprecation warning.
4298 2004-05-30 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4300 * eval.c (lookup_global_symbol, literal_p, try_macro_lookup):
4301 Modified to make set! work on symbols that represent syntactic
4304 2004-05-26 Han-Wen Nienhuys <hanwen@xs4all.nl>
4306 * gc.h (SCM_CELL_OBJECT_LOC): use SCM_GC_CELL_OBJECT to prevent
4307 compound expression as lvalue errors.
4309 2004-05-24 Marius Vollmer <mvo@zagadka.de>
4311 * dynwind.c (winder_mark): Use SCM_PACK to correctly convert the
4312 WINDER_DATA to a SCM.
4314 2004-05-24 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4316 * goops.c (compute_getters_n_setters, create_standard_classes,
4317 scm_add_slot): Compute closures by calling scm_i_eval_x on a
4318 lambda expression rather than creating them with scm_closure.
4320 2004-05-22 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4322 * eval.c (s_macro_keyword, scm_m_set_x): Remove checking for
4323 misplaced syntactic keywords. This will not work unless guile's
4324 defmacro feature is deprecated.
4326 (scm_m_case): Fixed a bug that caused the list of labels to grow
4327 with every case form.
4329 2004-05-19 Kevin Ryde <user42@zip.com.au>
4331 * numbers.c (scm_round_number): For inum and big, just return x. For
4332 real, use scm_round for 2^54-1 etc problems covered there.
4334 * numbers.c (trunc): Remove #define to scm_truncate when the C library
4335 doesn't provide trunc. This was for when `truncate' was done as a
4336 scm_tc7_dsubr, no longer required.
4338 * threads.c (scm_threads_mark_stacks) [SCM_STACK_GROWS_UP]: Correction
4339 to stack marking call, two parameters and no cast on t->base.
4341 2004-05-18 Marius Vollmer <mvo@zagadka.de>
4343 * hashtab.c (rehash_after_gc): Bug fix: properly link the
4344 processed hashtables back into the weak_hashtables list. Thanks
4345 to Bill Schottstaedt!
4347 2004-05-16 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4349 * eval.c (unmemoize_quote): New static function.
4351 (scm_m_quote, scm_m_atslot_ref, SCM_CEVAL): Changed the byte code
4352 representation of 'quote' and '@slot-ref' to an improper list.
4353 This reduces execution time, the number of cells used to hold the
4354 memoized code, and thus also reduces garbage collection time.
4356 (scm_unmemocopy): Use unmemoize_quote for quote expressions.
4358 (SCM_CEVAL): Changed macro handling to also work with macros that
4359 return improper lists. Added an assertion, that the code returned
4360 by a macro transformer will not lead to cycles in the memoized
4363 2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4365 No functional change, just rearrangements of functions within the
4368 * eval.c (scm_ilookup, scm_unbound_variable_key,
4369 error_unbound_variable, scm_lookupcar1, scm_lookupcar): Moved to
4370 the definitions used for execution, since that's where they will
4373 2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4375 * numbers.h (SCM_SLOPPY_FRACTIONP): Removed. It was not used
4376 throughout guile, has not been part of an official release yet,
4377 and the concept of sloppy predicates has never been a good idea.
4379 (SCM_FRACTION_NUMERATOR, SCM_FRACTION_DENOMINATOR,
4380 SCM_FRACTION_SET_NUMERATOR, SCM_FRACTION_SET_DENOMINATOR):
4383 2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4385 * throw.c (SETJBJMPBUF, SCM_SETJBDFRAME): Add cast to scm_t_bits
4386 to make explicit what happens.
4388 2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4390 * dynl.c (SET_DYNL_HANDLE): Add cast to scm_t_bits to make
4391 explicit what happens.
4393 * guardians.c (TCONC_IN): Use SCM_SET_CELL_OBJECT_x rather than
4394 SCM_SET_CELL_WORD_x when writing scheme objets to cell elements.
4396 2004-05-11 Marius Vollmer <mvo@zagadka.de>
4398 * scmsigs.c (scm_sigaction_for_thread): Validate that the handler
4399 is indeed a procedure when it isn't a number.
4401 2004-05-10 Marius Vollmer <mvo@zagadka.de>
4403 Convert floating point numbers into strings with an arbitrary
4404 radix. Thanks to Richard Todd!
4406 * numbers.c (FLOBUFLEN): Increase so that radix 2 strings will
4409 (scm_dblprec, fx_per_radix, init_dblprec, init_fx_radix,
4410 number_chars): New, to support variable radices.
4411 (idbl2str): Use above instead of the old base-10 only tables.
4412 (iflo2str): Pass on new RADIX argument to idbl2str.
4413 (scm_number_to_string): Pass radix to iflo2str.
4414 (scm_print_real, scm_print_complex): Explicitly pass radix 10 to
4416 (scm_init_numbers): Call init_dblprec and init_fx_radix for all
4419 2004-05-10 Kevin Ryde <user42@zip.com.au>
4421 * numbers.c (scm_logbit_p): Correction to test above the end of an
4422 inum. Reported by Jan Konecny.
4424 2004-05-06 Marius Vollmer <marius.vollmer@uni-dortmund.de>
4426 * gc.h (scm_t_cell): Fields are now of type SCM instead of
4427 scm_t_bits. Updated all users.
4428 (SCM_GC_CARD_SIZE_MASK): Use SCM_GC_SIZEOF_CARD instead of
4429 duplicating the code.
4430 (SCM_CELL_OBJECT_LOC): New.
4431 (SCM_CARLOC, SCM_CDRLOC): Use it instead of SCM_CELL_WORD_LOC.
4432 (SCM_CELL_WORD_LOC): Moved to "deprecated.h".
4434 * smob.h (SCM_SMOB_DATA_2, SCM_SMOB_DATA_3, SCM_SMOB_FLAGS,
4435 SCM_SET_SMOB_DATA_2, SCM_SET_SMOB_DATA_3, SCM_SET_SMOB_FLAGS,
4436 SCM_SMOB_OBJECT, SCM_SMOB_OBJECT_2, SCM_SMOB_OBJECT_3,
4437 SCM_SET_SMOB_OBJECT, SCM_SET_SMOB_OBJECT_2, SCM_SET_SMOB_OBJECT_3,
4438 SCM_SMOB_OBJECT_LOC, SCM_SMOB_OBJECT_2_LOC,
4439 SCM_SMOB_OBJECT_3_LOC): New.
4440 * smob.c (scm_i_set_smob_flags): New function.
4442 * dynl.c, dynwind.c, eval.h, fluids.h, futures.h, hashtab.h,
4443 hooks.h, keywords.h, macros.h, macros.c, mallocs.c, mallocs.h,
4444 random.h, regex-posix.h, root.h, srcprop.h, srcprop.c, threads.h:
4445 Use SCM_SMOB_* instead of SCM_CELL_* as appropriate. Use
4446 SCM_SMOB_FLAGS and SCM_SET_SMOB_FLAGS instead of accessing the
4447 zeroth word directly. Use SCM_SMOB_PREDICATE as appropriate.
4449 * numbers.h (SCM_I_BIG_MPZ): Use SCM_CELL_OBJECT_LOC instead of
4450 taking the address of SCM_CELL_WORD_1, the latter being no longer
4453 * variable.h (SCM_VARIABLE_LOC): Use SCM_CELL_OBJECT_LOC instead
4454 of casting SCM_CELL_WORD_LOC.
4456 2004-05-02 Kevin Ryde <user42@zip.com.au>
4458 * eval.c (scm_macroexp): Add prototype, since it's not in eval.h under
4459 --disable-deprecated. Reported by Andreas Vögele.
4461 * filesys.c (_POSIX_C_SOURCE): Define to 199506L to get readdir_r (in
4462 particular on HP-UX). Reported by Andreas Vögele.
4464 * list.c (varargs.h): Remove, leave just stdarg.h which is all the
4465 code has support for. Fixes building with AIX cc, which is ansi but
4466 doesn't define __STDC__. Reported by Keith Crane.
4467 (var_start): Remove macro, this variation no longer required.
4468 (scm_list_n): Use va_start directly.
4470 2004-05-01 Kevin Ryde <user42@zip.com.au>
4472 * continuations.c (scm_dynthrow): Use >= instead of SCM_PTR_GE which
4473 is now gone. Reported by Andreas Vögele.
4475 2004-04-28 Kevin Ryde <user42@zip.com.au>
4477 * backtrace.c (display_frame_expr), numbers.c (XDIGIT2UINT,
4478 mem2uinteger, mem2decimal_from_point, mem2ureal): Cast char to int for
4479 ctype.h tests, to avoid warnings from gcc on HP-UX about char as array
4480 subscript. Reported by Andreas Vögele.
4481 Also cast through unsigned char to avoid passing negatives to those
4482 macros if input contains 8-bit values.
4484 * num2integral.i.c (NUM2INTEGRAL): Under non-BIGMPZ_FITSP case,
4485 corrections to range check for signed numbers. Remove
4486 scm_remember_upto_here_1(num) from these checks, since num is used
4487 subsequently anyway.
4489 * num2integral.i.c (NUM2INTEGRAL): Test BIGMPZ_FITSP with "!= 0" to
4490 avoid warning from gcc 3.4. Reported by Hyperdivision.
4492 * numbers.c (scm_bit_extract): Use min instead of MIN.
4493 (MIN): Remove, this conflicts with similar macro defined by limits.h
4494 on HP-UX. Reported by Andreas Vögele.
4496 * stime.c (_POSIX_C_SOURCE): Define to 199506L to get gmtime_r (in
4497 particular on HP-UX). Reported by Andreas Vögele.
4499 * threads.c (scm_threads_mark_stacks): Correction sizet -> size_t.
4500 Reported by Andreas Vögele.
4502 * threads-plugin.h (SCM_MUTEX_MAXSIZE): Increase to 25*sizeof(long),
4503 for the benefit of hpux11 where pthread_mutex_t is 88 bytes. Reported
4506 2004-04-22 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4508 * eval.c (s_macro_keyword): New static identifier.
4510 (scm_m_define): Change order to first create binding and
4511 evaluating the expression afterwards.
4513 (scm_m_set_x): Memoize complete set! expression. Only leave
4514 symbols if no binding exists at memoization time. Throw error if
4515 assigning to a syntactic keyword.
4517 (lazy_memoize_variable): New function.
4519 (CEVAL): When execution set!, perform lazy memoization if
4520 unmemoized symbol is detected.
4522 * modules.c (module_variable): Return variables with unbound
4525 * tags.h: Fix comment.
4527 2004-04-25 Kevin Ryde <user42@zip.com.au>
4529 * chars.c (scm_char_upcase, scm_char_downcase, scm_c_upcase,
4530 scm_c_downcase): Use ctype.h toupper and tolower. This will be useful
4531 in 8-bit locales, and ensures consistency with char-upper-case? and
4532 char-lower-case? which already use ctype.h.
4533 (scm_c_upcase_table, scm_c_downcase_table, scm_lowers, scm_uppers):
4535 * chars.c, chars.h, init.c (scm_tables_prehistory): Remove.
4537 * socket.c (VALIDATE_INET6): Correction to bignum_in_ipv6_range_p
4538 call. Reported by Hyperdivision.
4540 * threads.c (scm_yield): Correction, actually call scm_thread_yield.
4541 Reported by Hyperdivision.
4543 * unif.c (s_scm_make_uve): Remove unused local variable. Reported by
4546 2004-04-22 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4548 Hide the implementation of ilocs and isyms in eval.c.
4550 * deprecated.h (SCM_IFRINC, SCM_ICDR, SCM_IFRAME, SCM_IDIST,
4551 SCM_ICDRP), eval.c (SCM_IFRINC, SCM_ICDR, SCM_IFRAME, SCM_IDIST,
4552 SCM_ICDRP), eval.h (SCM_ICDR, SCM_IFRINC, SCM_IFRAME, SCM_IDIST,
4553 SCM_ICDRP): Deprecated and added to deprecated.h. Moved from
4556 * deprecated.c (scm_isymnames), deprecated.h (scm_isymnames,
4557 SCM_ISYMNUM, SCM_ISYMCHARS), eval.c (SCM_ISYMNUM, isymnames,
4558 scm_unmemocopy, CEVAL), print.c (scm_isymnames), tags.h
4559 (SCM_ISYMNUM, scm_isymnames, SCM_ISYMCHARS): Deprecated
4560 scm_isymnames, SCM_ISYMNUM and SCM_ISYMCHARS and added to
4561 deprecated.[hc]. Moved scm_isymnames from print.c to eval.c and
4562 renamed to isymnames. Moved SCM_ISYMNUM from tags.h to eval.c and
4565 * eval.c (scm_i_print_iloc, scm_i_print_isym), eval.h
4566 (scm_i_print_iloc, scm_i_print_isym), print.c (scm_iprin1):
4567 Extracted printing of ilocs and isyms to guile internal functions
4568 scm_i_print_iloc, scm_i_print_isym of eval.c.
4570 2004-04-22 Kevin Ryde <user42@zip.com.au>
4572 * numbers.c (scm_bit_extract): Use SCM_SRS for signed right shift.
4574 * numbers.c (scm_round): Test for x already an integer, to avoid bad
4575 rounding in x+0.5 when x is a big value already an integer. In
4576 certain hardware rounding cases x+0.5 can give an adjacent integer,
4577 leading to that as the result, when we really just wanted x itself.
4579 2004-04-19 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4581 * eval.c (scm_unmemocopy): Fixed unmemoization of let*.
4583 (deval_args, CEVAL): Minor improvements: Reduced variable scopes,
4584 added const qualifiers, cast intentionally unused expressions to
4585 void for emphasis, improved comment.
4587 2004-04-18 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4589 * tags.h (scm_tags, scm_tc8_tags, scm_tc9_flag, scm_tc8_flag,
4590 scm_tc8_isym): Renamed scm_tags to scm_tc8_tags. Renamed
4591 scm_tc9_flag to scm_tc8_flag. Introduced new identifier
4592 scm_tc8_isym. Defined tc8-tags relative to scm_tc3_imm24.
4593 Defined the tc8-tag for flags to be 0x04, which will mean that
4594 SCM_BOOL_F will also have the value 0x04 instead of 0x013c. Due
4595 to the reduced number of bits and the simpler bit pattern for
4596 SCM_BOOL_F, certain machines may be able to use more efficient
4597 processor instructions to deal with SCM_BOOL_F.
4599 (SCM_ITAG9, SCM_MAKE_ITAG9, SCM_ITAG9_DATA): Removed. These have
4600 never been defined in a released version, thus no need to
4603 (SCM_IFLAGP, SCM_MAKIFLAG, SCM_IFLAGNUM): Flags now use tc8
4604 instead of tc9 tags.
4606 (SCM_ISYMP, SCM_MAKISYM, SCM_ISYMNUM): Isyms now use tc8 instead
4609 (SCM_MAKSPCSYM): Removed. It is almost impossible that user code
4610 could have used this definition.
4612 (SCM_IM_AND, SCM_IM_BEGIN, SCM_IM_CASE, SCM_IM_COND, SCM_IM_DO,
4613 SCM_IM_IF, SCM_IM_LAMBDA, SCM_IM_LET, SCM_IM_LETSTAR,
4614 SCM_IM_LETREC, SCM_IM_OR, SCM_IM_QUOTE, SCM_IM_SET_X): Now encoded
4615 as isyms, as special isyms don't exist any more.
4617 2004-04-18 Kevin Ryde <user42@zip.com.au>
4619 * filesys.c (scm_readdir): Use readdir_r when available, for thread
4622 * numbers.c (scm_max, scm_min): For big/real, use SCM_SWAP rather than
4623 explicit swapping code.
4625 2004-04-15 Kevin Ryde <user42@zip.com.au>
4627 * cpp_sig_symbols.in: Add SIGSYS.
4629 * list.c (scm_append_x): Use iterative style, to avoid non-tail
4632 * numbers.c (scm_max, scm_min): For inum/frac, frac/inum, big/frac,
4633 frac/big and frac/frac, use scm_less_p for exact comparison.
4635 * numbers.c (scm_gcd): For inum/big, use mpz_gcd_ui by sharing code
4638 * numbers.c (xisinf): Add a comment about solaris 7 lacking isinf.
4640 2004-04-06 Han-Wen Nienhuys <hanwen@xs4all.nl>
4642 * inline.h (scm_cell): use SCM_GC_CELL_WORD for checking tag.
4644 * chars.h (scm_init_chars): change scm_{upcase,downcase} to
4645 scm_c_{up,down}case.
4646 (SCM_MAKE_CHAR): add (unsigned char) cast. This prevents havoc
4647 when hi-bit ASCII is subjected to SCM_MAKE_CHAR().
4649 2004-04-06 Kevin Ryde <user42@zip.com.au>
4651 * numbers.c (scm_ash): Remove stray "}" in docstring.
4653 * numbers.c (scm_make_ratio): For inum/bignum integer detection, use
4654 x==SCM_MOST_NEGATIVE_FIXNUM explicitly, for clarity and to avoid
4655 calling mpz_cmp_ui in most cases.
4657 * numbers.c (scm_quotient, scm_remainder): In inum/big, use mpz_cmp_ui
4658 for big == abs(most-negative-fixnum) special case.
4659 (abs_most_negative_fixnum): Remove, no longer used.
4661 * scmsigs.c (scm_sigaction_for_thread): Correction to signum range
4662 test, avoids SCM_VECTOR_REF outside bounds of signal_handlers on
4663 calling (sigaction NSIG).
4665 * simpos.c (scm_system_star): Fix execargv memory leak, merge parent
4666 and fork error cases to do this.
4668 2004-04-03 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4670 * eval.c (CEVAL): Don't distinguish between short and long
4671 instructions when dispatching - just always dispatch on the
4672 instruction code, which is common for short and long instructions.
4673 Further, removed unnecessary goto statements and added comment.
4675 2004-04-03 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4677 * eval.c (scm_unmemocopy): Don't distinguish between short and
4678 long instructions when dispatching - just always dispatch on the
4679 instruction code, which is common for short and long instructions.
4680 Further, removed unnecessary goto statements, fixed indentation
4681 and replaced SCM_IMP predicates by SCM_NULLP.
4683 2004-04-03 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4685 * eval.c (scm_lookupcar1, CEVAL): Use SCM_ILOCP instead of
4686 comparison with SCM_ILOC00. In CEVAL, eliminate goto-label
4689 2004-03-31 Kevin Ryde <user42@zip.com.au>
4691 * simpos.c: Include <signal.h> for SIG_IGN and friends.
4693 2004-03-29 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4695 Introduce scm_debug_mode_p as a replacement for scm_debug_mode and
4698 * debug.h (scm_debug_mode_p, scm_debug_mode, SCM_DEBUGGINGP),
4699 eval.c (scm_debug_mode_p): Deprecated scm_debug_mode and
4700 SCM_DEBUGGINGP. Provided scm_debug_mode_p instead, to have one
4701 single interface that also matches the naming conventions.
4702 Probably scm_debug_mode_p should be part of the private interface
4705 * debug.h (scm_debug_mode_p), backtrace.c (display_error_body),
4706 eval.c (SCM_APPLY, scm_trampoline_0, scm_trampoline_1,
4707 scm_trampoline_2): Change uses of scm_debug_mode or SCM_DEBUGGINGP
4708 to scm_debug_mode_p.
4711 Deprecate direct access to scm_ceval, scm_deval and scm_ceval_ptr:
4713 * eval.h (scm_ceval, scm_deval, scm_ceval_ptr), debug.h
4714 (scm_ceval_ptr): Deprecated. Moved declaration of scm_ceval_ptr
4715 from debug.h to eval.h.
4717 * debug.h (SCM_RESET_DEBUG_MODE): Don't access scm_ceval_ptr any
4718 more, just leave it with setting scm_debug_mode_p, which is
4719 equivalent for practical purposes.
4721 * deprecated.h (SCM_XEVAL, SCM_XEVALCAR): Call scm_i_eval_x
4722 instead of *scm_ceval_ptr. Leave all evaluating to scm_i_eval_x.
4724 * gdbint.c (gdb_eval): Call scm_i_eval_x instead of scm_ceval.
4726 * eval.c (ceval, deval, scm_ceval, scm_deval): Made scm_ceval
4727 static and renamed it to ceval throughout. Provide a new exported
4728 but deprecated function scm_ceval as a wrapper for backwards
4729 compatibility. The same is done for the deval/scm_deval pair of
4732 * eval.c (CEVAL, SCM_CEVAL): Renamed SCM_CEVAL to CEVAL
4733 throughout. Defined CEVAL to ceval or deval, based on compilation
4736 * eval.c (SCM_XEVAL, SCM_XEVALCAR): Dispatch on scm_debug_mode_p
4737 to ceval and deval instead of calling *scm_ceval_ptr.
4739 * eval.c (dispatching_eval): New deprecated static function.
4741 * eval.c (scm_ceval_ptr): Initialized to dispatching_eval in order
4742 to emulate its old behaviour as closely as possible.
4745 Change the evaluator such that only expressions for which pair? is
4746 true are passed to CEVAL, and such that all other expressions are
4747 evaluated outside of CEVAL:
4749 * eval.c (EVAL): New, provided in analogy to EVALCAR. Evaluate an
4750 expression that is assumed to be memoized already. All but
4751 expressions of the form '(<form> <form> ...)' are evaluated inline
4752 without calling an evaluator.
4754 * eval.c (SCM_XEVAL, SCM_XEVALCAR, EVALCAR): Evaluate all but
4755 expressions of the form '(<form> <form> ...)' inline without
4756 calling an evaluator.
4758 * eval.c (scm_i_eval_x, scm_i_eval, scm_ceval, scm_deval): Handle
4759 the special case of unmemoized symbols passed on the top level.
4761 * eval.c (CEVAL): Change calls to CEVAL to EVAL, except where it
4762 is known that the expression passed to CEVAL is of the form
4763 '(<form> <form> ...)'. Remove handling of the tc7-objects, since
4764 now it is known that the input expression of CEVAL is a pair.
4766 2004-03-29 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4768 * eval.c (is_self_quoting_p): New static function.
4770 (scm_m_quote): Use is_self_quoting_p.
4772 (copy_tree): Corrected typo in comment.
4774 2004-03-28 Han-Wen Nienhuys <hanwen@xs4all.nl>
4776 * eval.c (s_scm_copy_tree): idem.
4778 * list.c (s_scm_filter): remove "pointer" from doc string.
4780 * gc.h (SCM_GC_CELL_TYPE): SCM_GC_CELL_TYPE uses SCM_GC_CELL_OBJECT.
4782 * goops.h (SCM_NUMBER_OF_SLOTS): don't SCM_UNPACK the result.
4784 * backtrace.c ("display_backtrace_body"): SCM_PACK before SCM_EQ_P
4785 (display_frame): idem.
4786 (display_backtrace_file_and_line): idem.
4788 * tags.h (SCM_UNPACK): stricter typechecking on SCM_UNPACK
4791 2004-03-26 Kevin Ryde <user42@zip.com.au>
4793 * filesys.c (scm_getcwd, scm_readlink): Avoid memory leak on errors.
4795 * numbers.c (scm_modulo): For inum/big and big/big, remove test of
4796 big==0 since that never occurs.
4798 * numbers.c, numbers.h (scm_modulo_expt): Renamed from
4799 scm_modular_expt, matching scheme level name `modulo-expt'.
4801 * numbers.c (scm_modular_expt): Return a negative remainder for a
4802 negative divisor, the same as `modulo' does.
4804 2004-03-26 Eric Hanchrow <offby1@blarg.net>
4806 * numbers.c, numbers.h (scm_modular_expt): New function.
4808 2004-03-25 Kevin Ryde <user42@zip.com.au>
4810 * numbers.c (scm_min, scm_max): Correction to big/real and real/big,
4811 return inexact as required by r5rs.
4813 2004-03-24 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4815 * eval.c: Separated some definitions relevant for execution from
4816 the memoization part of the file.
4818 (copy_tree): New static function
4820 (scm_copy_tree): Rewritten to fix two kinds or bugs: First, cyclic
4821 structures are detected now and will lead to an exception instead
4822 of forcing guile to run in an endless loop, using up all the
4823 system's memory. Second, arrays in the cdr of an improper list
4824 are now copied. See the new test cases in eval.test.
4826 2004-03-24 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4828 * posix.c (scm_gethostname): Make sure len is initialised before
4829 it is used. Restructured to (hopefully) represent possible
4830 configurations more clearly in the code. Added unwind handler.
4832 2004-03-23 Kevin Ryde <user42@zip.com.au>
4834 * posix.c (scm_gethostname): Use sysconf(_SC_HOST_NAME_MAX) and/or
4835 MAXHOSTNAMELEN when available.
4837 2004-03-21 Marius Vollmer <mvo@zagadka.de>
4839 * read.c (skip_scsh_block_comment): Also recognize '\r' as a line
4840 terminator. Rewritten the logic as a state machine, I must have
4841 been doing too much VHDL lately...
4843 * eval.c (scm_ceval, scm_deval): Explicitely evaluate ports to
4844 themselves. Thanks to Han-Wen Nienhuys!
4846 * list.c: Changed docstrings so that they no longer talk about
4847 returning 'pointers' to something.
4849 2004-03-20 Han-Wen Nienhuys <hanwen@xs4all.nl>
4851 * gc.c: remove set_debug_cell_accesses! when
4852 SCM_DEBUG_CELL_ACCESSES is not defined. Scheme source code should
4853 use (if (defined? 'set-debug-cell-accesses!) .. ) to switch on
4854 debugging conditionally.
4856 2004-03-21 Kevin Ryde <user42@zip.com.au>
4858 * stime.c (scm_gmtime): Use gmtime_r when available, for thread safety.
4860 2004-03-20 Kevin Ryde <user42@zip.com.au>
4862 * posix.c (scm_gethostname): Preserve errno across free() call.
4864 2004-03-18 Han-Wen Nienhuys <hanwen@xs4all.nl>

4869 2004-03-14 Kevin Ryde <user42@zip.com.au>
4871 * stime.c: Define _GNU_SOURCE for strptime prototype from glibc.
4872 (strptime): Use HAVE_DECL_STRPTIME for when to give own prototype.
4874 2004-03-07 Kevin Ryde <user42@zip.com.au>
4876 * stime.c (scm_gmtime): Return bd_time->tm_zone when available, rather
4878 (filltime): Make zname parameter "const".
4880 2004-03-03 Mikael Djurfeldt <mdj@chunk.mit.edu>
4882 * threads.c, threads.h (scm_c_scm2thread): New function.
4884 2004-02-29 Kevin Ryde <user42@zip.com.au>
4886 * numbers.c (guile_ieee_init): Use C99 INFINITY and NAN when
4887 available. Test HAVE_DINFINITY and HAVE_DQNAN for those globals, in
4888 particular don't assume "defined (__alpha__) && ! defined (linux)"
4889 means OSF. Remove "SCO" code, which was not really SCO specific and
4890 which John W. Eaton advises should be long past being needed.
4892 * posix.c (scm_execl, scm_execlp, scm_execle): Avoid memory leak under
4895 2004-02-24 Kevin Ryde <user42@zip.com.au>
4897 * posix.c (scm_cuserid): Use a private result buffer, for thread safe.
4899 2004-02-22 Kevin Ryde <user42@zip.com.au>
4901 * numbers.c (scm_max, scm_min): For one arg, dispatch to generic for
4902 complex, same as for two args. (Handle only inum, big, real, frac).
4904 2004-02-21 Kevin Ryde <user42@zip.com.au>
4906 * posix.c (scm_crypt): Use new HAVE_CRYPT.
4907 (<crypt.h>): Remove HAVE_LIBCRYPT condition.
4908 Reported by Andreas Voegele.
4910 2004-02-20 Neil Jerram <neil@ossau.uklinux.net>
4912 * list.c (scm_list_n): Add #if SCM_DEBUG_CELL_ACCESSES_P around
4915 * read.c (scm_lreadparen): Removed.
4916 (scm_lreadparen1): Renamed scm_i_lreadparen.
4918 2004-02-20 Han-Wen Nienhuys <hanwen@xs4all.nl>
4920 * list.c (scm_list_n): validate non-immediate arguments;
4921 this will catch forgotten a SCM_UNDEFINED.
4923 2004-02-18 Marius Vollmer <mvo@zagadka.de>
4925 * gc.h (scm_gc_cells_collected): Removed duplicated declaration.
4926 Thanks to Bill Schottstaedt!
4928 * socket.h (scm_gethost): Removed prototype it is already in
4929 "net_db.h". Thanks to Bill Schottstaedt!
4931 2004-02-18 Kevin Ryde <user42@zip.com.au>
4933 * num2integral.i.c (INTEGRAL2BIG): WORDS_BIGENDIAN not right for word
4934 order parameter to mpz_import, in fact with just one word there's no
4935 order to worry about at all.
4937 * numbers.c (scm_num_eq_p): For real==frac, complex==frac, frac==real
4938 and frac==complex, make an exact comparison rather than converting
4939 with fraction2double.
4941 * posix.c, putenv.c, stime.c (environ): Use _NSGetEnviron in Darwin
4942 shared library, since environ is not directly available there.
4944 * script.c (scm_shell_usage): Print to stdout for --help, per GNU
4947 * stime.c (scm_localtime, scm_gmtime, scm_mktime): Provide a default
4948 errno EINVAL in case localtime and gmtime don't set it.
4949 (scm_mktime, scm_strptime): Forcibly use errno EINVAL for our
4950 SCM_SYSERROR, since mktime and strptime generally don't set errno.
4952 2004-02-16 Kevin Ryde <kevin@swox.se>
4954 * gc-malloc.c (scm_done_malloc, scm_done_free): Allow negative sizes,
4955 which were permitted in the past for these.

4961 GNU standard. Reported by Han-Wen Nienhuys.
4963 2004-02-13 Mikael Djurfeldt <djurfeldt@nada.kth.se>
4965 * unif.c (scm_make_uve): Removed local variable and simplified
4966 code in order to avoid compiler used uninitialized warnings.
4968 * hashtab.c, hashtab.h (scm_hash_map_to_list): Renamed from
4970 (scm_hash_fold): Use scm_call_3 directly in the call to
4971 scm_internal_hash_fold instead of going via fold_proc (which is
4973 (scm_hash_for_each): Use a trampoline +
4974 scm_internal_hash_for_each_handle.
4975 (scm_internal_hash_for_each_handle, scm_hash_for_each_handle): New
4978 2004-02-12 Kevin Ryde <user42@zip.com.au>
4980 * ports.c (scm_port_line): In docstring, note first line is 0.
4981 (scm_set_port_line_x): In docstring, note first line is 0.
4982 (scm_port_column): In docstring, there's no default to current input
4983 port, and remove shared port-line @defun.
4984 (scm_set_port_column_x): In docstring, there's no default to current
4985 input port, note first column is 0, remove shared set-port-line!
4988 * ramap.c (scm_array_fill_x): For fvect and dvect, use scm_num2dbl to
4989 convert args the same way that array-set! does.
4991 * unif.c (scm_make_uve, scm_array_p): Allow fraction 1/3 as prototype
4993 (scm_array_p): Add missing "break"s in switch, fix llvect test look
4994 for "l" not "s", fix dvect to be false for singp(prot) since such a
4996 (scm_array_prototype): Return 1/3 for dvect, rather than 0.33..33.
4997 (exactly_one_third): New variable.
4998 (scm_init_unif): Initialize it.
5000 2004-02-10 Neil Jerram <neil@ossau.uklinux.net>
5002 * read.c (scm_read_opts): Change `escaped-parens' to
5005 2004-02-08 Neil Jerram <neil@ossau.uklinux.net>
5007 * read.c (scm_read_opts): New opts `elisp-vectors' and
5010 (scm_lreadr): Use scm_lreadparen1 instead of scm_lreadparen. Make
5011 handling of elisp vector syntax dependent on SCM_ENABLE_ELISP and
5012 `elisp-vectors' option instead of SCM_ELISP_READ_EXTENSIONS.
5013 Allow "\(" and "\)" in strings when SCM_ENABLE_ELISP defined and
5014 `escaped-parens' option set.
5015 (scm_read_token): If elisp vector syntax active, disallow [ and ]
5017 (scm_lreadparen): Rewrite as interface to scm_lreadparen1.
5018 (scm_lreadparen1): New.
5020 * read.h: Remove conditionally compiled last arg to
5022 (SCM_ELISP_VECTORS_P, SCM_ESCAPED_PARENS_P): New.
5024 2004-01-23 Han-Wen Nienhuys <hanwen@xs4all.nl>
5026 * eval.c (m_expand_body): remove stray variable new_body.
5028 2004-01-22 Marius Vollmer <mvo@zagadka.de>
5030 * eval.c (m_expand_body): Rewrite the expression in place (by
5031 overwriting FORMS) also when a letrec is constructed, not only
5032 when no definitions are found. Do not return rewritten expression
5033 to emphasize the in-place rewriting. Changed all users.
5035 2004-01-19 Han-Wen Nienhuys <hanwen@xs4all.nl>
5037 * gc.c: add protected_object_count, a number that is dumped from
5040 2004-01-11 Marius Vollmer <mvo@zagadka.de>
5042 * dynwind.h, dynwind.c (scm_frame_unwind,
5043 scm_frame_unwind_handler): Renamed and changed all uses.
5044 (scm_frame_rewind, scm_frame_rewind_handler): Likewise.
5046 2004-01-11 Kevin Ryde <user42@zip.com.au>
5048 * unif.c (scm_bit_count, scm_bit_position, s_scm_bit_set_star_x,

5050 changes made to scheme-compound.texi.
5052 2004-01-10 Marius Vollmer <mvo@zagadka.de>
5054 * print.c (scm_print_symbol_name): Handle #{`foo}#, #{,foo}#,
5055 #{.}#, and all numeric strings specially. Thanks to Paul Jarc!
5057 * guile-snarf.in: Use mkdir to create a unique temporary directory
5058 that we can safely use. Thanks to Stefan Nordhausen!
5060 2004-01-07 Marius Vollmer <marius.vollmer@uni-dortmund.de>
5062 * dynwind.h, dynwind.c (scm_i_dowinds): Removed 'explicit'
5063 argument since it is always zero now. Changed all callers.
5064 Removed code for handling fluids.
5066 * fluids.c (scm_c_with_fluids): Use frames instead of adding to
5067 the wind chain explicitely. Use scm_c_with_fluid for the common
5068 case of only one fluid.
5069 (scm_with_fluid): New.
5070 (scm_c_with_fluid): Use frames instead of scm_c_with_fluids.
5072 * fluids.h, fluids.c (scm_frame_fluid): New.
5073 (scm_with_fluid): New.
5074 (scm_i_swap_fluids, scm_i_swap_fluids_reverse): Removed.
5076 * dynwind.c (scm_frame_end): Do not use scm_i_dowinds. Instead,
5077 do the unwinding directly. It is simple enough.
5079 * dynwind.h, dynwind.c: Did the following renamings:
5080 scm_begin_frame -> scm_frame_begin,
5081 scm_end_frame -> scm_frame_end,
5082 scm_on_unwind -> scm_frame_unwind,
5083 scm_on_rewind -> scm_frame_rewind,
5084 scm_on_unwind_with_scm -> scm_frame_unwind_with_scm,
5085 scm_on_rewind_with_scm -> scm_frame_rewind_with_scm.
5088 * aync.h, async.c: Did the follwing renamings:
5089 scm_with_blocked_asyncs -> scm_frame_block_asyncs,
5090 scm_with_unblocked_asyncs -> scm_frame_unblock_asyncs.
5093 * ports.h, ports.c: Did the follwing renamings:
5094 scm_with_current_input_port -> scm_frame_current_input_port,
5095 scm_with_current_output_port -> scm_frame_current_output_port,
5096 scm_with_current_error_port -> scm_frame_current_error_port.
5099 2004-01-07 Kevin Ryde <user42@zip.com.au>
5101 * numbers.c (s_bignum): Remove, not used since gmp bignums.
5102 Reported by Richard Todd.
5104 * threads-plugin.h (SCM_MUTEX_MAXSIZE): Increase to 12*sizeof(long),
5105 for the benefit of powerpc-apple-darwin5.5. Reported by Richard Todd.
5107 * unif.c (scm_aind): Test SCM_CONSP rather than !SCM_NULLP while
5108 traversing the args list, fixes segv if an improper list is given.
5109 Reported by Rouben Rostamian.
5111 2004-01-06 Marius Vollmer <marius.vollmer@uni-dortmund.de>
5113 * ports.c (swap_ports, scm_with_current_foo_port): Do not allocate
5114 swap_data on stack, use a 'malloc obj'.
5116 * fluids.h, fluids.c (scm_make_initial_fluids, scm_copy_fluids,
5117 scm_swap_fluids, scm_swap_fluids_reverse): Renamed to
5118 scm_i_... since they are internal. Changed all uses.
5120 * dynwind.c (frame_print): Removed, use the default printer.
5121 (WINDER_F_MARK, WINDER_MARK_P, winder_mark): New.
5122 (scm_on_unwind_with_scm, scm_on_rewind_with_scm): New. Use above
5123 to protect SCM values.
5125 * dynwind.h (SCM_F_WIND_EXPLICITELY,
5126 SCM_F_WIND_EXPLICITLY): It's "explicitly" not "explicitely", damn.
5128 (scm_on_unwind_with_scm, scm_on_rewind_with_scm): New.
5130 2004-01-05 Marius Vollmer <mvo@zagadka.de>
5132 * ports.h, ports.c (scm_with_current_input_port,
5133 scm_with_current_output_port, scm_with_current_error_port): New.
5135 * async.h, async.c (scm_with_blocked_asyncs,
5136 scm_with_unblocked_asyncs): New.
5138 2004-01-03 Marius Vollmer <mvo@zagadka.de>
5140 * dynwind.h, scm_dynwind.c (scm_t_frame_flags, scm_t_wind_flags,
5141 scm_begin_frame, scm_end_frame, scm_on_unwind, scm_on_rewind):
5143 (scm_dowinds, scm_i_dowinds): scm_dowinds has been renamed to
5144 scm_i_dowinds and extended to handle frames and to invoke a 'turn'
5145 function when the outermost wind point has been reached. The
5146 latter is used to copy a continuation stack at the right time.
5147 scm_dowinds remains available.
5148 (SCM_GUARDSP, SCM_BEFORE_GUARD, SCM_AFTER_GUARD, SCM_GUARD_DATA,
5149 tc16_guard, guards_print): Removed.
5150 (scm_internal_dynamic_wind): Reimplemented using frames.
5152 * continuations.c (copy_stack): New, do only the stack copying
5153 part of copy_stack_and_call.
5154 (copy_stack_and_call): Copy the stack after unwinding and before
5156 (scm_dynthrow): Do not call scm_dowinds, this is now done by
5157 copy_stack_and_call.
5159 2004-01-04 Kevin Ryde <user42@zip.com.au>
5161 * numbers.c (scm_less_p): Don't convert frac to float for compares,
5162 can give bad results due to rounding.
5164 * stime.c (scm_current_time, scm_gettimeofday): Add a comment about
5165 setzone/restorezone protection for DOS.
5167 2003-12-26 Marius Vollmer <mvo@zagadka.de>
5169 * gen-scmconfig.h.in, gen-scmconfig.c: Arrange for scm_t_intmax
5170 and scm_t_uintmax to be defined in scmconfig.h
5172 2003-12-03 Kevin Ryde <user42@zip.com.au>
5174 * numbers.c (scm_less_p): Remove spurious xisnan from frac+big case.
5176 * numbers.c (scm_make_ratio): Check for numerator equal to
5177 SCM_MOST_NEGATIVE_FIXNUM and bignum denominator the negative of that,
5180 * numbers.c (scm_real_part): Return fraction unchanged rather than
5181 converting to flonum.
5183 2003-11-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
5185 * modules.c (module_variable): Fixed (and thus simplified) the
5186 definition of SCM_BOUND_THING_P to reflect the fact that since
5187 after the 1.4 series of guile, obarrays only hold variable
5190 2003-11-30 Marius Vollmer <mvo@zagadka.de>
5192 * numbers.c (scm_logand): It's "#b...", not "#\b...".
5196 * read.c (scm_lreadr): Signal an error for invalid escape
5197 sequences in strings. Code cleanups too.
5199 * print.c (scm_iprin1): use \xNN hexadecimal sequences when
5200 writing control characters in strings.
5202 2003-11-21 Marius Vollmer <mvo@zagadka.de>
5204 * ports.c (scm_drain_input): Bug fix: only access the port after
5205 checking that it indeed is one.
5207 2003-11-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
5209 * eval.c (s_bad_define): New static identifier.
5211 (m_body): Fixed comment.
5213 (scm_m_define): Don't generate memoized code for definitions that
5214 are not on the top level. As a consequence, no memoized code at
5215 all is generated for definitions any more: Top level definitions
5216 are executed immediately during memoization and internal
5217 definitions are handled separately in m_expand_body.
5219 (scm_unmemocopy, unmemocopy): Removed code for unmemoizing
5220 definitions. Consequently, there is no unmemoizing code any more
5221 that might modify the environment. Thus, the old scm_unmemocopy
5222 is removed and the old unmemocopy is renamed to scm_unmemocopy.
5224 (SCM_CEVAL): The SCM_IM_DEFINE keyword can no longer occur in
5225 memoized code. Call EVALCAR for continuations. Prefer !SCM_NULLP
5226 over SCM_NIMP in places, where the argument is known to be part of
5229 2003-11-21 Kevin Ryde <user42@zip.com.au>
5231 * numbers.c (scm_abs): Allocate a new real only for negatives, as done
5234 * numbers.c (scm_bit_extract): Use mpz functions, rearrange inum case
5235 to share some shifting.
5237 * numbers.c (scm_integer_expt): Don't mpz_init after scm_i_clonebig or
5238 scm_i_mkbig, since they do so already. Don't mpz_clear a bignum SCM,
5241 2003-11-19 Marius Vollmer <mvo@zagadka.de>
5243 * numbers.c (scm_make_ratio): Rewritten to have a simpler
5244 structure. Previously, not all cases with a negative denominator
5247 * numbers.c (mem2decimal_from_point): use scm_divide instead of
5248 scm_divide2real when forming the fractional part. This allows
5249 "#e1.2" to yield 6/5.
5251 * numbers.c (scm_i_fraction_equalp): Do not treat the return value
5252 of scm_equal_p as a C boolean, use SCM_FALSEP. Previously, all
5253 fractions were equal to each other regardless of value. Ooops.
5255 * numbers.c (scm_rationalize): Return an inexact result when given
5258 * numbers.c (scm_exact_p, scm_inexact_p): Throw error for
5261 2003-11-18 Marius Vollmer <marius.vollmer@uni-dortmund.de>
5263 Support for exact fractions from Bill Schottstaedt! Thanks!
5265 * print.c (scm_iprin1): Handle fractions.

5699 into subtypes of scm_tc7_number.
5701 * tags.h (scm_tc7_number): New.
5703 * eq.c (scm_equal_p), eval.c (SCM_CEVAL), evalext.c

5707 (scm_class_of), print.c (scm_iprin1), smob.c
5708 (scm_smob_prehistory): Don't handle bignums, reals and complex
5709 numbers as subtypes of scm_tc7_smob any more.
5711 * numbers.h, tags.h (scm_tc16_big, scm_tc16_real,
5712 scm_tc16_complex): Moved definitions from tags.h to numbers.h.
5714 2003-09-18 Dirk Herrmann <D.Herrmann@tu-bs.de>

5729 2003-09-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
5731 This set of patches eliminates the dependency between the
5732 implementation of evaluator specific memoization codes and special
5733 constants like #f, '() etc. ('flags'), which are not evaluator
5734 specific. The goal is to remove definitions of evaluator
5735 memoization codes completely from the public interface. This will
5736 make it possible to experiment more freely with optimizations of
5737 guile's internal representation of memoized code.
5739 * objects.c (scm_class_of): Eliminate dependency on SCM_ISYMNUM.
5741 * print.c (iflagnames): New array, holding the printed names of
5742 guile's special constants ('flags').
5744 (scm_isymnames): Now holds only the printed names of the
5747 (scm_iprin1): Separate the handling of memoization codes and
5748 guile's special constants.
5750 * tags.h (scm_tc9_flag, SCM_ITAG9, SCM_MAKE_ITAG9, SCM_ITAG9_DATA,
5753 (scm_tc8_char, scm_tc8_iloc, SCM_BOOL_F, SCM_BOOL_T,

5756 SCM_IM_SLOT_SET_X, SCM_IM_DELAY, SCM_IM_FUTURE,
5757 SCM_IM_CALL_WITH_VALUES, SCM_IM_NIL_COND, SCM_IM_BIND): Changed
5760 (SCM_IFLAGP): SCM_IFLAGP now only tests for flags.
5762 (SCM_IFLAGP, SCM_MAKIFLAG, SCM_IFLAGNUM): Generalized to use the
5763 tc9 macros and scm_tc9_flag.
5765 2003-09-15 Marius Vollmer <mvo@zagadka.de>

5768 long. Thanks to Paul Jarc!
5770 2003-09-14 Dirk Herrmann <D.Herrmann@tu-bs.de>
5772 * tags.h: Reduced the number of short instructions from 14 to 13.
5773 The typecode of the former 14th short instruction is now used to
5774 represent long instructions. Changed some comments to reflect
5777 (SCM_MAKISYM): ISYMs get a new tc7 code, namely the one that was
5778 previously used by SCM_IM_DEFINE.
5780 (SCM_IM_DEFINE): Turned into a long instruction.
5782 * eval.c (unmemocopy, SCM_CEVAL): Treat SCM_IM_DEFINE as a long
5785 * eval.c (SCM_CEVAL): Since characters and iflags have now a tc7
5786 code that is separate from all instructions, one level of dispatch
5787 for long instructions can be eliminated.
5789 * print.c (scm_isymnames): Removed some commented code.
5791 2003-09-12 Marius Vollmer <mvo@zagadka.de>
5793 * __scm.h (SCM_FENCE): Use __memory_barrier with the Intel
5796 * hashtab.h (scm_tc16_hashtable): Added "extern" declaration.
5798 * modules.c (scm_module_reverse_lookup): Check that the obarray
5799 really is a hashtable and do nothing if not.
5801 * inline.h: Use "extern inline" only with GCC. Use "static
5804 2003-09-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
5806 * numbers.h (SCM_INEXACTP, SCM_REALP, SCM_COMPLEXP): Removed uses
5807 of SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP.
5809 * numbers.h, deprecated.h (SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP,
5810 SCM_SLOPPY_COMPLEXP): Deprecated and moved from numbers.h to
5813 2003-09-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
5815 * eq.c (scm_eqv_p, scm_equal_p): Removed uses of
5816 SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP.
5818 * eq.c (scm_eqv_p, scm_equal_p): Reordered comparisons from
5819 0.0==some_expression to some_expression==0.0. The latter is
5820 better readable. The former is preferred by some people, since it
5821 leads to a compiler error when confusing == with =. However, when
5822 using gcc, a warning will be issued if in an if-statement an
5823 assigment appears. Since many Guile developers are using gcc,
5824 such errors will not remain unnoticed anyway. We can therefore
5825 focus on better readability.
5827 2003-09-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
5829 * tags.h: Added description of Guile's type system. Removed some
5830 old and misleading comments.

5834 * unit.c (scm_cvref): Eliminate unnecessary uses of SCM_NIMP,
5835 SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP.
5837 2003-09-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
5839 * numbers.h (SCM_MAKINUM): Define in terms of scm_tc2_int.
5841 (SCM_INEXACTP, SCM_REALP, SCM_COMPLEXP): Define in terms of the
5842 respective SLOPPY macro.
5844 2003-09-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
5846 * eq.c (scm_equal_p): Use SCM_TYP7 to check if an object is of
5847 type string, not SCM_TYP7S.
5849 2003-09-03 Kevin Ryde <user42@zip.com.au>
5851 * numbers.c (scm_lognot): Correction to docstring, ones-complement not
5854 * stime.c (scm_strptime): Add comment about glibc strptime %s and
5855 current timezone requiring SCM_DEFER_INTS.

5859 * script.c (scm_compile_shell_switches): Make -s switch optional
5860 if file to be loaded does not begin with a `-'. (Thanks to Aaron
5861 VanDevender for the patch!)
5863 2003-08-30 Kevin Ryde <user42@zip.com.au>
5865 * numbers.c (scm_lognot): Rewrite using ~ and mpz_com, for directness
5866 and to have non-integer types rejected as per other logical funcs.
5868 2003-08-28 Kevin Ryde <user42@zip.com.au>
5870 * gc.h (scm_remember_upto_here_1): Revise comments on the asm form.
5872 2003-08-23 Kevin Ryde <user42@zip.com.au>
5874 * simpos.c (scm_system): Remove SCM_DEFER_INTS, system() should be
5875 thread safe, and could take a long time too.
5877 2003-08-22 Kevin Ryde <user42@zip.com.au>
5879 * numbers.c (scm_difference): Correction to bignum - negative inum.
5881 2003-08-14 Kevin Ryde <user42@zip.com.au>
5883 * gc.h (scm_remember_upto_here_1, scm_remember_upto_here_2)
5884 [__GNUC__]: Use volatile asm macros rather than a function call.
5885 * gc.c (scm_remember_upto_here_1, scm_remember_upto_here_2): Undefine
5886 macros while defining functions.
5888 * simpos.c (getenv): Use <stdlib.h> for prototype.

5892 2003-08-09 Kevin Ryde <user42@zip.com.au>
5894 * srcprop.c (scm_source_properties): Return plist from hash if it's a
5895 list set by source-properties! rather than an SRCPROPS object,

5899 * properties.c (scm_primitive_property_ref): In docstring, note
5900 parameters to not-found-proc, use hyphens rather than underscores for
5901 that parameter name.
5902 (scm_primitive_property_set_x): In docstring, VAL is the value
5905 2003-07-27 Marius Vollmer <mvo@zagadka.de>
5907 * print.c (scm_print_symbol_name): handle more weird characters by
5908 escaping the symbol name properly. Thanks to Paul Jarc!
5910 * posix.h (scm_setgroups): New prototype.
5911 * posix.c (scm_setgroups): New. Thanks to Paul Jarc!
5912 (scm_getgroups): Handle groups ids that don't fit into a fixnum.
5913 Don't use SCM_WRITABLE_VELTS.
5915 * gc.h (SCM_GC_SET_CELL_BVEC): New.
5916 * gc-card.c (scm_i_init_card_freelist): Use it. Thanks to
5919 * __scm.h (SCM_C_INLINE_KEYWORD): New.
5920 * numbers.c: Use it in place of SCM_C_INLINE so that the code
5921 compiles when SCM_C_INLINE is undefined.
5923 2003-07-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
5925 * __scm.h: Reformulated the architecture and compiler properties
5926 in terms of properties of scm_t_bits and SCM variables rather than
5927 in terms of c standard types. This is since it is not known which
5928 of the standard types scm_t_bits and SCM variables will be defined
5931 2003-07-24 Kevin Ryde <user42@zip.com.au>
5933 * numbers.c (scm_angle): Use scm_flo0 for non-negative inum, bignum
5936 2003-07-18 Kevin Ryde <user42@zip.com.au>
5938 * numbers.c (scm_product): In complex * bignum, correction to
5939 REAL/IMAG fetch, x is the complex, not y.
5941 2003-07-13 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5943 * numbers.c (scm_odd_p, scm_even_p): Bugfix: Treat result of
5944 scm_inf_p test as Scheme values.
5945 (scm_sum): Bugfix: Normalize bignum created from a negative bignum
5946 and a positive inum.
5947 Use GNU indentation style.
5949 2003-07-12 Dirk Herrmann <D.Herrmann@tu-bs.de>
5951 * values.c (scm_values): Build lists of length 1 by using
5952 scm_list_1 instead of using scm_cons.
5954 2003-07-10 Kevin Ryde <user42@zip.com.au>
5956 * deprecation.c (scm_c_issue_deprecation_warning_fmt): Add va_end.
5957 * list.c (scm_list_n): Ditto.
5959 * gc-malloc.c (scm_gc_realloc): Define "ptr" at start of function.
5961 2003-07-08 Matthias Koeppe <mkoeppe@merkur.math.uni-magdeburg.de>
5963 * tags.h (scm_t_bits, scm_t_signed_bits, etc): Avoid solaris empty
5964 defines of INTPTR_MAX and UINTPTR_MAX, combine conditionals for
5965 scm_t_bits and scm_t_signed_bits to avoid any chance of one and not
5966 the other using intptr_t.
5968 2003-07-08 Kevin Ryde <user42@zip.com.au>
5970 * numbers.c (scm_make_polar): Use sincos, when available.
5971 (scm_magnitude): Use hypot.
5973 * ports.c (scm_char_ready_p, scm_peek_char): In docstrings, don't use
5974 @footnote since it doesn't go through to guile-procedures.txt.
5976 * threads.c (scm_call_with_new_thread): In docstring, use "( )"
5977 outside @var to quieten makeinfo, and use @code.
5979 2003-07-06 Han-Wen Nienhuys <hanwen@cs.uu.nl>
5981 * gc-malloc.c (decrease_mtrigger): new function
5982 (increase_mtrigger): new function, separate debug registering and
5983 mtrigger administration.
5984 (scm_gc_realloc): bugfix: do mtrigger administration before the
5985 actual realloc, for the realloc might invalidate a GC-d segment of
5986 memory. Thanks to Sam Hocevar for pointing this out.
5987 (scm_gc_realloc): use scm_malloc_reregister instead of
5988 unregistering and registering in sequence.
5990 2003-07-03 Han-Wen Nienhuys <hanwen@cs.uu.nl>
5992 * __scm.h (SCM_ASSERT): change "else" expansion to "do { } while (0)"

5996 * __scm.h (SCM_ASRTGO): add "else" to macro expansions with if
5999 2003-06-29 Marius Vollmer <mvo@zagadka.de>
6001 * deprecated.h (SCM_OPDIRP, scm_fport, scm_option, scm_srcprops,
6002 scm_srcprops_chunk, scm_info_frame, scm_stack, scm_array,
6003 scm_array_dim, SCM_ARRAY_CONTIGUOUS, SCM_FUNC_NAME, SCM_WTA,
6004 RETURN_SCM_WTA, SCM_VALIDATE_NUMBER_COPY,
6005 SCM_VALIDATE_NUMBER_DEF_COPY, SCM_VALIDATE_OPDIR): Re-added from
6006 the release_1_6 branch.
6008 2003-06-25 Stefan Jahn <stefan@lkcc.org>

6011 __asm__ ("getcontext") directive.
6013 * continuations.h: Include <ucontext.h> instead of
6016 2003-06-21 Kevin Ryde <user42@zip.com.au>
6018 * numbers.c (_GNU_SOURCE): #define, to get C99 things.
6019 (scm_asinh, scm_acosh, scm_atanh, scm_truncate, $asinh, $acosh,
6020 $atanh, truncate): Use C library asinh, acosh, atanh and trunc, when
6022 (scm_inexact_to_exact): Expand isfinite to its definition !xisinf.
6023 (isfinite): Remove, conflicts with C99 isfinite().

6031 scm_symbol_bound_p, scm_symbol_set_x, scm_gentemp): Re-added from
6032 the release_1_6 branch.
6034 2003-06-14 Stefan Jahn <stefan@lkcc.org>
6036 * threads.h: Redefined scm_getspecific() and scm_setspecific()
6037 to be functions instead of macros.
6039 * threads.c: Conditionalized inclusion of <sys/time.h> and
6041 (scm_getspecific, scm_setspecific): Made these two function
6042 real part of the API.
6044 * posix.c (s_scm_putenv): Added some code to make a
6045 (putenv "FOO="), i.e. setting an empty string, work also on
6046 Win32 systems. Thanks to Kevin Ryde for the proposal.
6048 2003-06-12 Kevin Ryde <user42@zip.com.au>
6050 * posix.c (scm_putenv): Free temporary ptr in mingw unset. Add
6051 freebsd to comment about need to use unsetenv.

6055 * ports.c (scm_peek_char): Safe the column of the port around the
6056 getc/ungetc calls. Thanks to Dr. Peter Ivanyi!
6058 2003-06-07 Kevin Ryde <user42@zip.com.au>
6060 * tags.h: Use inttypes.h and stdint.h when available, for INTPTR_MAX

6063 2003-06-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
6065 * tags.h (scm_tc2_int): Added.
6067 * tags.h (scm_tc3_int_1, scm_tc3_int_2): Expressed in terms of

6071 scm_tcs_closures): Hard coded values replaced by symbolic ones.
6073 2003-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
6075 * eval.c: Partially undid my patch from 2003-05-31. This patch
6076 caused the segfault referenced in the previous changelog entry.
6078 2003-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
6080 * tags.h: Fixed comment about the immediate type code layout.
6082 * eval.c: Fixed handling of non-special instructions. Without
6083 this patch, guile will segfault on (#\0) and similar instructions.
6085 2003-06-05 Kevin Ryde <user42@zip.com.au>
6087 * numbers.c (scm_max, scm_min): For inum, bignum and real, if other
6088 operand is NaN, then return NaN. Also avoid passing NaN to mpz_cmp_d.
6090 * read.c (scm_input_error): Pass arg list parameter to scm_error_scm,
6091 rather than SCM_EOL. Needed by "Unknown # object" case in scm_lreadr.
6093 2003-06-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
6095 * __scm.h, gc-card.c (SCM_DEBUG_DEBUGGER_SUPPORT,
6096 SCM_DEBUG_DEBUGGING_SUPPORT): Renamed macro
6097 SCM_DEBUG_DEBUGGER_SUPPORT to SCM_DEBUG_DEBUGGING_SUPPORT and
6098 generalized it to apply not only to C level functions but also to
6099 scheme level functions.

6102 scm_iloc_p, dbg-make-iloc, scm_dbg_make_iloc, dbg-iloc?,
6103 scm_dbg_iloc_p): Moved functions scm_make_iloc, scm_iloc_p to
6104 eval.c, made them available under SCM_DEBUG_DEBUGGING_SUPPORT == 1
6105 only and renamed them to scm_dbg_make_iloc, scm_dbg_iloc_p,
6108 * deprecated.h, eval.c, eval.h (SCM_ILOC00, SCM_IDINC,
6109 SCM_IDSTMSK): Deprecated. The macro definitions are moved from
6110 eval.h into eval.c and a copy is placed into deprecated.h.
6112 * eval.c, eval.h (SCM_MAKE_ILOC): Removed from eval.h and placed
6113 into eval.c. This definition was not part of the API in any
6114 officially released version of guile and thus does not need to go
6115 through a phase of deprecation.
6117 2003-06-02 Dirk Herrmann <D.Herrmann@tu-bs.de>
6119 * deprecated.c, deprecated.h, eval.c, eval.h (scm_s_expression,
6120 scm_s_test, scm_s_body, scm_s_bindings, scm_s_variable,
6121 scm_s_clauses, scm_s_formals): Deprecated. In eval.c the
6122 definitions are make static and renamed from scm_s_xxx to s_xxx.
6123 In deprecated.c the original definitions are copied.
6125 * deprecated.h, eval.c, eval (SCM_EVALIM2, SCM_EVALIM, SCM_XEVAL,
6126 SCM_XEVALCAR): Deprecated. The macro definitions are moved from
6127 eval.h into eval.c and a copy (slightly modified to work in user
6128 code) is placed into deprecated.h.
6130 * eval.c: Use the local static s_xxx definitions instead of the
6131 scm_s_xxx definitions throughout.
6133 2003-06-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
6135 This set of patches separates the representation of the cxr family
6136 of functions (car, cdr etc.) from the dsubr family of functions
6137 (i. e. functions that take a double precision floating point
6138 argument). Further, the algorithm for handling the cxr function

6146 (scm_tc7_dsubr, scm_tcs_subrs): Introduce scm_tc7_dsubr as new
6147 typecode for the dsubr family of functions.
6149 * ramap.c (ramap_cxr, ramap_dsubr): Renamed ramap_cxr to
6152 * eval.c (SCM_CEVAL, SCM_APPLY, call_cxr_1), pairs.c
6153 (scm_init_pairs): Make use of the (now usable) second cell element
6154 of a scm_tc7_cxr function to implement the cxr family of functions
6157 2003-05-31 Dirk Herrmann <D.Herrmann@tu-bs.de>
6159 * eval.c (SCM_CEVAL, SCM_APPLY, scm_trampoline_0,
6160 scm_trampoline_1, scm_trampoline_2): Postpone error cases to the
6161 end of an if-else-if-sequence of checks.
6163 2003-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
6165 * eval.c (SCM_CEVAL): Improved readability of call-with-values
6166 execution. Generalize apply_closure to apply_proc and use that
6167 for call-with-values.
6169 2003-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
6171 * eval.c (SCM_CEVAL): Avoid one level of indirection when applying

6192 * stime.c (s_scm_strftime): Add a type cast to avoid compiler
6195 * posix.c (s_scm_putenv): Disable use of unsetenv() for the
6198 * modules.c (s_scm_module_import_interface): Renamed local
6199 variable interface to _interface. Seems like 'interface'
6200 is a special compiler directive for the mingw32 compiler.
6202 * mkstemp.c: Provide prototype to avoid compiler warning.
6204 * load.c (s_scm_search_path): Fixed absolute and relative
6205 path detections for native Windows platforms.
6207 * gc.h, threads.h: Export some more symbols using SCM_API (necessary
6208 to build on mingw32).
6210 * gc-freelist.c ("s_scm_map_free_list",
6211 "s_scm_gc_set_debug_check_freelist_x"): Fixed use of FUNC_NAME.

6223 proper function object and the correct number of arguments are now
6224 performed in the application part of SCM_CEVAL.
6226 (scm_badformalsp): Removed.
6228 2003-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>

6280 a compilation error if error-on-warning is enabled).
6282 2003-05-17 Marius Vollmer <mvo@zagadka.de>

6286 otherwise confuse us. These directives appear when compiling with

6304 2003-05-13 Kevin Ryde <user42@zip.com.au>
6306 * numbers.c (xmpz_cmp_d): New macro, handling infs if gmp doesn't.
6307 (scm_num_eq_p, scm_less_p, scm_max, scm_min): Use it.
6309 2003-05-12 Mikael Djurfeldt <djurfeldt@nada.kth.se>
6311 * backtrace.c (scm_display_error_message): Introduced fancy
6312 printing with max level 7 and length 10. (Purpose: avoid printing
6313 gigantic objects in error messages.)
6315 * print.c, print.h (scm_i_port_with_print_state): New function.
6317 * print.c (scm_iprin1, scm_printer_apply,
6318 scm_port_with_print_state): Use scm_i_port_with_print_state.

6325 Use current names in definitions.
6327 2003-05-10 Kevin Ryde <user42@zip.com.au>
6329 * numbers.c (scm_num_eq_p, scm_less_p): Don't pass NaN to mpz_cmp_d.
6331 * numbers.c (scm_integer_length): On negative bignums, adjust
6332 mpz_sizeinbase to account for it looking at absolute value where we
6333 want ones-complement.
6335 * numbers.c (scm_gcd): In bignum/inum, don't pass yy==0 to mpz_gcd_ui
6336 since we're only using the ulong return value, and x might not fit.
6338 2003-05-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
6340 * eval.c, eval.h, read.c, read.h (scm_sym_dot): Moved from eval to
6341 read. This will allow to make the definition in read.c static.
6343 2003-05-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
6345 * eval.c, eval.h, evalext.c, evalext.h (scm_m_undefine): Moved

6351 * numbers.c (scm_difference): In inum - bignum, handle negative inum.
6352 (scm_logcount): Use mpz_com, not mpz_neg.
6354 2003-05-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
6356 The purpose of this patch is to make guile's internal memoizers
6357 distinguishable from memoizing macros created on the scheme level
6358 or from user provided primitive memoizing macros. The reason is,
6359 that the internal memoizers are the only ones that are allowed to
6360 transform their scheme input into memoizer byte code, while all
6361 other memoizing macros may only transform scheme code into new
6364 To achieve this, a new macro type 'builtin-macro!' is introduced.
6365 Currently, 'builtin-macro!'s are handled as memoizing macros, but
6366 this will change when the memoizer and executor are separated.
6368 * macros.[ch] (scm_i_makbimacro): New.
6370 * macros.h (SCM_BUILTIN_MACRO_P): New.
6372 * macros.c (macro_print, scm_macro_type): Support builtin-macro!s.
6374 * eval.c, goops.c: All of guile's primitive memoizing macros are
6375 primitive builtin-macros now.
6377 * eval.c (scm_macroexp, SCM_CEVAL): Make sure the primitive
6378 builtin-macros are handled equally to memoizing macros.
6380 2003-05-04 Marius Vollmer <mvo@zagadka.de>
6382 * throw.c (scm_ithrow): Remove "asm volatile" hack. It used to
6383 work around a bug in GCC 2.95.2 but is now a bug in itself.
6385 2003-05-02 Marius Vollmer <mvo@zagadka.de>
6387 * deprecated.h (scm_rstate, scm_rng, SCM_SLOPPY_CONSP,
6388 SCM_SLOPPY_NCONSP, scm_tc7_ssymbol, scm_tc7_msymbol,
6389 scm_tcs_symbols): New.
6391 2003-04-30 Marius Vollmer <marius.vollmer@uni-dortmund.de>
6393 * deprecated.h, deprecated.c (scm_protect_object,

6407 2003-04-28 Mikael Djurfeldt <djurfeldt@nada.kth.se>
6409 * eval.c (scm_m_atdispatch): Removed until actually needed. (This
6410 macro was introduced in anticipation of GOOPS method compilation
6413 * goops.c: Removed binding of @dispatch.
6415 2003-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
6417 * eval.c, goops.c (@dispatch, @slot-ref, @slot-set!): Move the
6418 instructions that bind the macros on the scheme level back to
6419 goops.c in order to make sure again that the bindings go into the
6420 (oop goops) module and are not visible from the outside.
6422 2003-04-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
6424 * eval.c: Non functional change: Separated R5RS and non-R5RS
6425 macros into different sections of the file and ordered the
6426 memoizers alphabetically.
6428 2003-04-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
6430 * eval.c (scm_ilookup): Rewritten to improve readability.
6432 2003-04-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
6434 * eval.c (scm_i_call_closure_0, call_closure_1, call_closure_2):
6435 Partially reverted patch from 2003-04-23 in oder to find a better
6436 compromise between readability and debuggability.
6438 2003-04-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
6440 * eval.c, eval.h, goops.c, goops.h (scm_m_atslot_ref,
6441 scm_m_atslot_set_x, scm_m_atdispatch): Move the declarations and
6442 definitions of the special goops memoizers from goops.[ch] to
6443 eval.[ch]. Hmm... it seems that scm_m_atdispatch is not used
6446 2003-04-24 Mikael Djurfeldt <mdj@kvast.blakulla.net>
6448 * ports.c, ports.h (scm_i_port_table_mutex): New mutex.

6465 2003-04-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
6467 This set of patches contains no functional changes, only debatable
6468 minor stylistic ones. Still, in order to prepare a patch between
6469 my local copy and the CVS version, I decided to submit the changes
6470 below. Then, the patch will hopefully only contain relevant
6473 * eval.c (iqq): Added const specifier.
6475 * eval.c (scm_trampoline_0, scm_trampoline_1, scm_trampoline_2):
6476 Use NULL instead of 0 to indicate that a pointer is returned.
6477 Removed some misleading 'fall through' comments.

6485 * eval.h (SCM_ENTER_FRAME_HDLR, SCM_APPLY_FRAME_HDLR,
6486 SCM_EXIT_FRAME_HDLR): Use SCM_PACK to convert data to a SCM value
6487 rather than casting to SCM.
6489 2003-04-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
6491 * sort.c, pairs.h: Removed unnecessary includes.
6493 2003-04-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
6495 * sort.c: Replaced hand-made trampline code by the new official
6496 mechanism from eval.c. This fixes a segfault in the new test file
6499 (quicksort, compare_function, scm_restricted_vector_sort_x,
6500 scm_sorted_p, scm_merge, scm_merge_list_x, scm_merge_x,
6501 scm_merge_list_step, scm_sort_x, scm_sort, scm_merge_vector_x,
6502 scm_merge_vector_step, scm_stable_sort_x, scm_stable_sort,
6503 scm_sort_list_x, scm_sort_list): Use trampoline mechanism from
6506 (subr2less, lsubrless, closureless, applyless, scm_cmp_function,
6507 cmp_fun_t): Removed.
6509 (compare_function): Added.
6511 * sort.c (quicksort, SWAP, stack_node): Replaced pointer
6512 arithmetics with index arithmetics. Changed quicksort to work on
6513 an array of SCM values instead of an array of characters. Avoid
6514 bytewise copying of SCM elements. Avoid allocating memory on the
6515 stack with alloca. Fixed some comments.
6517 2003-04-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
6519 * eval.c (EXTEND_ENV): Eliminated.
6521 (unmemocopy, SCM_CEVAL, SCM_APPLY): Use SCM_EXTEND_ENV instead of

6529 compiling with SCM_DEBUG==1 by moving definition behind prototype.
6531 * gc.card.c (scm_dbg_t_list_cell, scm_dbg_t_double_cell,
6532 scm_dbg_gc_marked_p, scm_dbg_gc_get_card, scm_dbg_gc_get_bvec,
6533 scm_t_list_cell_struct, scm_t_list_cell, scm_t_double_cell,
6534 scm_gc_marked_p, scm_gc_get_card, scm_gc_get_bvec): Fixed
6535 functions such that they check if the object is a non-immediate.
6536 Further, renamed identifiers to use the scm_dbg_ prefix and made
6537 their inclusion into the lib dependent of the
6538 SCM_DEBUG_DEBUGGER_SUPPORT compile time option.
6540 2003-04-21 Dirk Herrmann <D.Herrmann@tu-bs.de>

6545 2003-04-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
6547 * list.c (scm_ilength, scm_last_pair), unif.c (l2ra): Prefer
6548 !SCM_CONSP over SCM_NCONSP. Now, guile itself does not include
6549 any calls to SCM_NCONSP any more.
6551 * unif.c (l2ra): Eliminate redundant check.
6553 2003-04-21 Dirk Herrmann <D.Herrmann@tu-bs.de>

6564 other expressions into an expression of their own.
6566 2003-04-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
6568 * goops.c (TEST_CHANGE_CLASS, scm_sys_initialize_object): Don't
6569 compare SCM values with !=.
6571 2003-04-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
6573 * eval.c, eval.h, evalext.c, evalext.h (scm_sym_setter,
6574 scm_m_generalized_set_x, scm_init_evalext): Move the declaration
6575 and definition of the memoizer for the generalized set! macro from
6576 evalext.[ch] to eval.[ch]. Use the SCM_SYNTAX snarfer macro to
6577 define the macro object.
6579 * eval.c, eval.h (s_set_x, scm_s_set_x, scm_m_set_x,
6580 scm_m_generalized_set_x): Since now scm_s_set_x is only used in
6581 eval.c, it is made static and renamed to s_set_x.

6586 2003-04-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
6588 * eval.c, root.h (scm_undefineds, SCM_NUM_PROTECTS, undefineds,
6589 scm_init_eval): Made scm_undefineds static in eval.c, renamed it
6590 to undefineds and registered the object as a permanent object.
6592 * eval.c, eval.h (scm_f_apply, scm_init_eval): Made scm_f_apply
6593 static in eval.c, renamed it to f_apply and registered the object
6594 as a permanent object.
6596 2003-04-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
6598 * eval.c (SCM_BIT7, SCM_BIT8, unmemocopy, SCM_CEVAL): Renamed
6599 file-local macro SCM_BIT8 to SCM_BIT7, which is more appropriate.
6601 2003-04-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
6603 * numbers.c (scm_logtest): Fixed argument bug in the call to
6604 mpz_and, which showed up when compiling with SCM_DEBUG defined.

6659 * tags.h: scm_t_intptr should have been intptr_t.
6661 2003-04-13 Rob Browning <rlb@defaultvalue.org>
6663 * __scm.h (SCM_FLUSH_REGISTER_WINDOWS): don't just rely on "sparc"
6665 #if defined (sparc) || defined (__sparc__) || defined (__sparc)
6666 as gc_os_dep.c suggests is appropriate.
6668 * goops.c (prep_hashsets): make static to match prototype.
6669 (scm_sym_args): SCM_SYMBOL -> SCM_GLOBAL_SYMBOL. Thanks to Albert
6672 * c-tokenize.lex: remove trailing comma from enum. Thanks to

6705 * init.c: #include gmp.h.
6707 * numbers.h: remove the gmp.h #include (not needed now).
6709 * posix.h: change occurences of "id" to something else so we don't
6710 cause trouble when included via objective-c (can't hurt, might
6711 help). Still have usage in debug.h, though.
6713 2003-04-06 Mikael Djurfeldt <djurfeldt@nada.kth.se>
6715 * random.c (scm_c_random_bignum): Don't generate a random number

6718 (scm_c_default_rstate): Use SCM_VARIABLE_REF to access
6719 scm_var_random_state.
6721 * num2integral.i.c (INTEGRAL2BIG): Put negation of n inside then

7201 decide what to output. See gen-scmconfig.c for details.
7202 (noinst_PROGRAMS): add gen-scmconfig.
7203 (gen_scmconfig_SOURCES): new variable.
7204 (gen-scmconfig.$(OBJEXT)): new target - be careful to handle
7205 cross-compiling right.
7206 (scmconfig.h): build scmconfig.h from gen-scmconfig's output.
7207 (BUILT_SOURCES): add scmconfig.h.

7249 generic if not enabled.
7250 (scm_sys_goops_loaded): Setup unextended primitive generics.
7252 * goops.c, goops.h (scm_c_extend_primitive_generic): New function.
7254 * snarf.h (SCM_PRIMITIVE_GENERIC, SCM_PRIMITIVE_GENERIC_1): New
7257 * numbers.c (scm_abs): Use SCM_PRIMITIVE_GENERIC. (This is only a
7258 testing example. All uses of SCM_GPROC should be converted.)
7260 * procprop.c (scm_stand_in_scm_proc): Use scm_assq instead of
7263 * eq.c (scm_equal_p): Turned into a primitive generic.
7265 2003-02-27 Rob Browning <rlb@defaultvalue.org>
7267 * Makefile.am (scmconfig.h): new target -- generate file from
7269 (modinclude_HEADERS): remove version.h.

7272 2003-02-24 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7274 This fixes a serious GC bug, introduced during the latest
7275 reorganization of the GC, which disabled freeing of structs and
7278 * struct.c (scm_struct_prehistory): Init scm_i_structs_to_free to
7280 (scm_struct_prehistory): Move scm_free_structs to
7281 scm_before_mark_c_hook.
7283 * gc-card.c (sweep_card): Check that we haven't swept structs on
7284 this card before. That can happen if scm_i_sweep_all_segments has
7285 been called from some other place than scm_igc.
7287 2003-02-19 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7289 * environments.c (DEFAULT_OBARRAY_SIZE): Changed from 137 to 31
7290 (since hash tables now adapt their size).
7292 * modules.c (scm_modules_prehistory): Changed from 2001 to 1533
7293 (current number of prehistory bindings; hashtable code will select
7294 a prime which is greater than this value).
7296 * symbols.c (scm_symbols_prehistory): Changed from 1009 to 2139
7297 (current number of initial symbols).
7299 * properties.c (scm_init_properties): Don't specify size of
7300 scm_properties_whash.
7302 * objprop.c (scm_init_objprop): Don't specify size of
7305 * keywords.c (scm_init_keywords): Don't specify a hash table size.
7307 * hooks.c (scm_c_hook_add): Fixed bug in append mode.
7309 The following changes introduce the use of resizable hash tables
7310 throughout Guile. It also renames the old *-hash-table* functions
7311 to *-alist-vector* and places them, together with the rest of the
7312 weak vector support, in the module (ice-9 weak-vector). We should
7313 probably introduce a new, better, API for weak references, for
7314 example "weak pairs" a la MIT-Scheme. (In Chez scheme, they even
7315 look like and are used like ordinary pairs.)
7317 * environments.c (obarray_enter, obarray_retrieve, obarray_remove,
7318 leaf_environment_fold, obarray_remove_all): Use hashtable
7321 * gc.c (scm_init_storage): Moved hook initialization to
7322 scm_storage_prehistory.
7323 (scm_storage_prehistory): New function.
7324 (scm_igc): Added commentary about placement of
7325 scm_after_sweep_c_hook.

7333 (scm_vector_to_hash_table, scm_c_make_resizing_hash_table):
7335 (scm_make_weak_key_hash_table, scm_make_weak_value_hash_table,
7336 scm_make_doubly_weak_hash_table): Moved here from weaks.c.
7338 * init.c (scm_init_guile_1): Removed call to scm_init_weaks; Added
7339 calls to scm_storage_prehistory and scm_hashtab_prehistory.
7341 * modules.c (module-reverse-lookup): Use hashtable accessors.
7343 * symbols.c, symbols.h (scm_i_hash_symbol): New function.
7345 * weaks.c, weaks.h (scm_make_weak_key_alist_vector,

7352 SCM_WVECTF_NOSCAN, SCM_WVECT_WEAK_KEY_P, SCM_WVECT_WEAK_VALUE_P,
7353 SCM_WVECT_NOSCAN_P): New macros.
7355 * weaks.c (scm_scan_weak_vectors): Use SCM_WVECT_WEAK_KEY_P
7356 and SCM_WVECT_WEAK_VALUE_P.
7358 * weaks.c, weaks.h (scm_i_allocate_weak_vector): Renamed from
7359 allocate_weak_vector and exported.
7361 2003-02-13 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7363 * hashtab.c: Undid thread safety. (We decided that it's better to
7364 let the user explicitly protect the tables (or not) according what
7365 is suitable for the application.)
7367 2003-02-12 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7369 * hashtab.c (scm_hash_fn_remove_x, scm_internal_hash_fold): Made
7370 thread safe and handle resizing tables.
7371 (scm_ihashx, scm_sloppy_assx, scm_delx_x): Removed

7394 * debug.c (scm_procedure_source): Handle all objects for which
7395 procedure? is #t. (Thanks to Bill Schottstaedt.)
7397 2003-01-23 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7399 * futures.c (mark_futures): Don't need to mark data of recycled
7401 (scan_futures, cleanup_undead): Be smarter about marking
7402 futures---avoid unnecessary passes through future lists.
7404 * futures.h, futures.c: New files; Introduced recycling of
7405 futures. For fine-grained threading this lifts performance to
7406 another level. We can now use parallelization in inner loops of
7407 Guile programs without impossible overhead.
7409 * threads.h, threads.c: Moved futures to their own file.
7411 * Makefile.am (libguile_la_SOURCES): Added futures.c.

7435 2003-01-22 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7437 * threads.c (create_thread): Don't unwind dynwind chain of parent
7438 thread before creation. Just start the new thread with an empty

7448 waiting also for simple condition variables.
7450 * goops.c (TEST_CHANGE_CLASS): Use scm_change_object_class instead
7451 of calling the procedure change-object-class.
7453 2003-01-09 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7455 * ramap.c (scm_ramapc): Typo in error message.
7457 2003-01-08 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7459 * goops.c (scm_sys_prep_layout_x): Bugfix: Only create layout for
7460 slots with instance allocation.
7462 * goops.c, goops.h (scm_class_extended_generic_with_setter): New
7464 (scm_compute_applicable_methods): Use scm_generic_function_methods.
7466 * goops.c (scm_generic_function_methods): Support extended
7469 2002-12-29 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7471 * eval.c (unmemocopy): Bugfix: scm_sym_delay --> scm_sym_future.
7472 Thanks to Neil for pointing this out!
7474 2002-12-29 Neil Jerram <neil@ossau.uklinux.net>
7476 * lang.h: Remove declarations matching definitions removed from
7477 lang.c (just below).
7479 2002-12-28 Neil Jerram <neil@ossau.uklinux.net>
7481 * lang.c (scm_nil_cons, scm_nil_car, scm_nil_cdr, scm_null,
7482 scm_m_while, scm_nil_eq): Remove definitions that were superfluous
7483 and already commented out.
7485 * read.h (scm_lreadparen), read.c (scm_lreadr, scm_read_token,
7486 scm_lreadparen): Support reading vectors with Elisp syntax if
7487 SCM_ELISP_READ_EXTENSIONS is defined. (SCM_ELISP_READ_EXTENSIONS
7488 is not currently defined, and there isn't even a configure switch
7491 2002-12-26 Marius Vollmer <mvo@zagadka.ping.de>
7493 * Makefile.am (c-tokenize.o): Refer to source via $< so that vpath
7495 (EXTRA_DIST): Added version.h.in.
7497 2002-12-21 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7499 This change makes it possible for one thread to do lazy sweeping
7500 while other threads are running. Now only the mark phase need to
7501 have all threads asleep. We should look further into this issue.
7502 Presently, I've put the locking of scm_i_sweep_mutex at
7503 "conservative" places due to my current lack of knowledge about
7504 the garbage collector. Please feel free to restrict these regions
7505 further to allow for maximal parallelism!
7507 * gc.c, gc.h (scm_i_sweep_mutex): New mutex.
7509 * gc.c (scm_gc_for_newcell), gc-malloc.c (scm_realloc,
7510 scm_gc_register_collectable_memory): Substitute locking of
7511 scm_i_sweep_mutex for calls to scm_i_thread_put_to_sleep.
7512 (scm_igc): Lock sweep mutex here instead of in callers; Calls to
7513 scm_i_thread_put_to_sleep/scm_i_thread_wake_up used to demarkate
7514 the single-thread section (which now only contains the mark
7516 (scm_gc): Don't lock sweeo mutex here since scm_igc locks it;
7517 Removed SCM_DEFER/ALLOW_INTS. Simply call scm_igc directly.
7519 * threads.c (gc_section_mutex): Removed.
7521 2002-12-19 Mikael Djurfeldt <mdj@kvast.blakulla.net>
7523 * threads.c (create_thread): Clear parent field in root state in
7524 order not to unnecessarily remember dead threads.
7526 * eval.c (call_subr2o_1, call_lsubr2_2): New functions.
7527 (scm_trampoline_1, scm_trampoline_2): Use them.
7529 2002-12-18 Mikael Djurfeldt <mdj@kvast.blakulla.net>
7531 Partial introduction of real plugin interface.
7533 * Makefile.am (modinclude_HEADERS): Added threads-plugin.h.
7534 (EXTRA_DIST): Added threads-plugin.c.
7536 * threads-plugin.h, threads-plugin.c: New files.
7538 * threads.h: #include "libguile/threads-plugin.h".
7540 * threads.c: #include "libguile/threads-plugin.c".
7542 * pthread-threads.c: Temporarily remove debugging functions.
7544 * threads.c, threads.h (scm_yield): Added back.
7546 2002-12-18 Mikael Djurfeldt <mdj@kvast.blakulla.net>
7548 * threads.c (really_launch): Detach before unlocking
7549 thread_admin_mutex in order not to risk being joined.
7550 (scm_i_thread_put_to_sleep, scm_i_thread_wake_up): Keep
7551 thread_admin_mutex locked during GC.
7553 * pthread-threads.c, pthread-threads.h: Improvements to debugging
7556 2002-12-16 Mikael Djurfeldt <mdj@kvast.blakulla.net>
7558 * pthread-threads.c, pthread-threads.h (SCM_DEBUG_THREADS): Added
7559 support for debugging mutex operations.
7561 * threads.c (scm_thread): Removed filed joining_threads.
7562 (thread_print): Print thread number as well as address of thread
7564 (scm_join_thread): Bugfix.
7565 (scm_lock_mutex, scm_try_mutex, scm_unlock_mutex,
7566 scm_timed_wait_condition_variable, scm_signal_condition_variable,
7567 scm_broadcast_condition_variable): Use the low-level API.
7568 (scm_all_threads): Return copy of thread list (to prevent
7569 unintended destruction).
7570 (scm_threads_prehistory): Initialize heap_mutex of fake thread.
7572 * pthread-threads.c, pthread-threads.h, threads.c: Fixes to
7573 pthread "native" recursive mutex support.
7575 2002-12-15 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7577 * __scm.h (SCM_DEFER_INTS, SCM_ALLOW_INTS): New definitions.
7578 Simply lock a thread C API recursive mutex.
7579 (SCM_NONREC_CRITICAL_SECTION_START,
7580 SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START,
7581 SCM_REC_CRITICAL_SECTION_END): Removed.
7583 * eval.c: Replaced SOURCE_SECTION_START / SOURCE_SECTION_END with
7584 direct calls to scm_rec_mutex_lock / unlock around the three calls
7585 to scm_m_expand_body.
7587 * eval.c, eval.h (promise_free): New function.
7588 (scm_force): Rewritten; Now thread-safe; Removed
7589 SCM_DEFER/ALLOW_INTS.
7591 * pthread-threads.h: Added partially implemented plugin interface
7592 for recursive mutexes. These are, for now, only intended to be
7593 used internally within the Guile implementation.
7595 * pthread-threads.c: New file.
7597 * threads.c: Conditionally #include "pthread-threads.c".
7599 * eval.c, eval.h (scm_makprom, scm_force): Rewritten to be
7602 * snarf.h (SCM_MUTEX, SCM_GLOBAL_MUTEX, SCM_REC_MUTEX,
7603 SCM_GLOBAL_REC_MUTEX): New macros.
7605 * eval.c, threads.c, threads.h, snarf.h: Rewrote critical section
7606 macros---use mutexes instead.
7608 * tags.h (SCM_IM_FUTURE): New tag.
7610 * eval.c (scm_m_future): New primitive macro.
7611 (SCM_CEVAL): Support futures.
7612 (unmemocopy): Support unmemoization of futures.
7614 * print.c (scm_isymnames): Name of future isym.
7616 * version.c: Unmade some changes to my private copy that got
7617 committed by mistake.
7619 2002-12-11 Mikael Djurfeldt <mdj@kvast.blakulla.net>
7621 * gc-malloc.c, gc.h, init.c: Reverted gc-malloc change of
7624 * gc.c (scm_igc): Don't call scm_i_thread_invalidate_freelists.
7626 * gc.c (scm_gc_sweep): Call it here instead, which is a more
7629 * threads.c (create_thread): Remember root object until the handle
7630 of the new thread is on all_threads list.
7632 * root.c (scm_make_root): Moved copying of fluids until after
7633 creation of root handle so that the fluids are GC protected. Also
7634 removed the critical section.
7636 2002-12-10 Mikael Djurfeldt <mdj@kvast.blakulla.net>
7638 * gc-malloc.c, gc.h (scm_gc_malloc_prehistory): New function.
7640 * gc-malloc.c (malloc_mutex): New mutex.
7641 (scm_gc_malloc_prehistory): Initialize it.
7642 (scm_realloc): Serialize call to realloc
7643 (scm_calloc): Same for calloc.
7644 Thanks to Wolfgang Jaehrling!
7645 (Now we have to make sure all calls to malloc/realloc are made
7646 through scm_malloc.)
7648 * init.c (scm_init_guile_1): Call scm_gc_malloc_prehistory.
7650 * threads.c (really_launch): Release heap (to prevent deadlock).
7651 (create_thread): Release heap before locking thread admin mutex.
7653 2002-12-10 Mikael Djurfeldt <mdj@kvast.blakulla.net>
7655 * threads.c (scm_i_thread_invalidate_freelists): New
7658 * gc.c (scm_igc): Call scm_i_thread_invalidate_freelists.
7660 * modules.c (scm_export): Inserted a return statement.
7662 2002-12-10 Han-Wen Nienhuys <hanwen@cs.uu.nl>
7664 * modules.c (scm_export): new function
7666 * gc-card.c: add a note about malloc()/free() overhead.
7668 2002-12-10 Mikael Djurfeldt <mdj@kvast.blakulla.net>
7670 * Makefile.am (c-tokenize.$(OBJEXT)): Don't look for c-tokenize.c
7673 2002-12-10 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7675 These changes remove scm_ints_disabled (which hasn't has any
7676 effect in Guile for quite some time).
7678 * async.c, error.h (scm_ints_disabled): Removed.
7680 * gc.c (scm_gc_for_newcell), init.c (scm_init_guile_1),
7681 root.c (scm_internal_cwdr), gdbint.c (SCM_BEGIN_FOREIGN_BLOCK,
7682 SCM_END_FOREIGN_BLOCK): Don't touch scm_ints_disabled.
7683 (old_ints): Removed.
7685 * __scm.h (SCM_DEFER_INTS, SCM_ALLOW_INTS): Define as a recursive
7687 (SCM_REDEFER_INTS, SCM_ALLOW_INTS): Define as SCM_DEFER_INTS and
7690 2002-12-09 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7692 * threads.c (scm_mutex_lock, scm_cond_wait, scm_cond_timedwait):
7693 Removed accidental #if 0 around these functions.
7695 These changes are the start of support for preemptive
7696 multithreading. Marius and I have agreed that I commit this code
7697 into the repository although it isn't thoroughly tested and surely
7698 introduces many bugs. The bugs should only be exposed when using
7699 threads, though. Signalling and error handling for threads is
7700 very likely broken. Work on making the implementation cleaner and
7701 more efficient is needed.
7703 * __scm.h (SCM_ALLOW_INTS_ONLY): Removed.
7704 (SCM_NONREC_CRITICAL_SECTION_START,
7705 SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START,
7706 SCM_REC_CRITICAL_SECTION_END): New macros.
7707 (SCM_CRITICAL_SECTION_START/END): Defined here.
7709 * eval.c: Insert SOURCE_SECTION_START / SOURCE_SECTION_END around
7710 the three calls to scm_m_expand_body.
7712 * gc.h: #include "libguile/pthread-threads.h";
7713 (SCM_FREELIST_CREATE, SCM_FREELIST_LOC): New macros.
7715 * gc.c (scm_i_freelist, scm_i_freelist2): Defined to be of type
7718 * gc.c, gc-freelist.c, inline.h: Use SCM_FREELIST_LOC for freelist
7721 * gc-freelist.c (scm_gc_init_freelist): Create freelist keys.
7723 * gc-freelist.c, threads.c (really_launch): Use
7724 SCM_FREELIST_CREATE.
7726 * gc-malloc.c (scm_realloc, scm_gc_register_collectable_memory):
7728 * gc.c (scm_i_expensive_validation_check, scm_gc,
7729 scm_gc_for_newcell): Put threads to sleep before doing GC-related
7730 heap administration so that those pieces of code are executed
7731 single-threaded. We might consider rewriting these code sections
7732 in terms of a "call_gc_code_singly_threaded" construct instead of
7733 calling the pair of scm_i_thread_put_to_sleep () and
7734 scm_i_thread_wake_up (). Also, we would want to have as many of
7735 these sections eleminated.
7737 * init.c (scm_init_guile_1): Call scm_threads_prehistory.
7739 * inline.h: #include "libguile/threads.h"
7741 * pthread-threads.h: Macros now conform more closely to the
7742 pthreads interface. Some of them now take a second argument.
7744 * threads.c, threads.h: Many changes.
7746 2002-12-09 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7748 * Makefile.am (version.h): Changed $^ --> $< in rule for
7751 2002-12-08 Rob Browning <rlb@defaultvalue.org>
7753 * version.h.in (SCM_MICRO_VERSION): use @--@ substitution now.
7754 (SCM_MINOR_VERSION): use @--@ substitution now.
7755 (SCM_MICRO_VERSION): use @--@ substitution now.
7756 (scm_effective_version): new function prototype.
7758 * version.c (scm_effective_version): new function, also add
7761 * Makefile.am (schemelibdir): VERSION -> GUILE_EFFECTIVE_VERSION.
7762 (libpath.h): use GUILE_EFFECTIVE_VERSION to compute
7764 (version.h): generate this here rather than configure.in. This
7765 approach tracks source edits better (i.e. more immediately).
7766 Might be worth considering for other .in files too.
7768 2002-12-02 Marius Vollmer <mvo@zagadka.ping.de>
7770 Reorganized thread package selection. A thread package now only
7771 implements a small set of pthread like functions and Guile
7772 implements the rest on top of that. Guile's implementation is
7773 what the "coop-pthreads" package has been previously. Support for
7774 "coop" threads has been removed until I get time to add it again.
7776 * Makefile.am (libguile_la_SOURCES): Removed iselect.c.
7777 (noinst_HEADERS): Removed coop-threads.c, coop-threads.h, coop.c,
7778 null-threads.c, coop-pthreads.c.
7779 (modinclude_HEADERS): Removed coop-defs.h, coop-pthreads.h. Added
7782 * validate.h (SCM_VALIDATE_THREAD): Moved to threads.h.
7784 * threads.h: Do not include "libguile/coop-defs.h". Include
7785 "libguile/pthread-threads.h" for USE_COPT_THREADS. Removed
7786 (previously deprecated) C level thread API prototypes. They are
7787 now in the thread package specific headers, "null-threads.h" and
7788 "pthread-threads.h".
7789 (SCM_VALIDATE_THREAD, SCM_VALIDATE_MUTEX, SCM_VALIDATE_CONDVAR):
7791 (scm_threads_init): Removed.
7792 (SCM_CRITICAL_SECTION_START, SCM_CRITICAL_SECTION_END,
7793 SCM_THREAD_SWITCHING_CODE, scm_i_switch_counter,
7794 SCM_I_THREAD_SWITCH_COUNT): Define here.
7795 (scm_single_thread_p): Removed.
7796 (scm_call_with_new_thread): Take two args directly instead of list
7798 (scm_i_thread_data, scm_i_set_thread_data, SCM_THREAD_LOCAL_DATA,
7799 SCM_SET_THREAD_LOCAL_DATA): Define here.
7801 * threads.c: Merged with "coop-pthreads.c".
7803 * null-threads.h: Implement pthread-like API as a set of macros.
7805 * pthread-threads.h: New, implement pthread-like API by deferring
7808 * init.c (scm_init_guile_1): Do not call scm_init_iselect, which
7809 has been lost in the reorganization.
7811 2002-12-01 Mikael Djurfeldt <mdj@linnaeus>
7813 The following change makes it possible to move procedure
7814 application dispatch outside inner loops. The motivation was
7815 clean implementation of efficient replacements of R5RS primitives
7818 The semantics is clear: scm_trampoline_N returns an optimized
7819 version of scm_call_N (or NULL if the procedure isn't applicable
7822 Applying the optimization to map and for-each increases efficiency
7823 noticeably. For example, (map abs ls) is 8 times faster than
7826 * eval.h (scm_t_trampoline_1, scm_t_trampoline_2): New types.
7828 * eval.c, eval.h (scm_trampoline_1, scm_trampoline_2): New functions.
7830 * eval.c (call_subr2_2, call_lsubr_2, call_closure_2): New functions;
7831 (map, for-each): Handle also application on two args as a special
7832 case; Use trampolines.
7836 * sort.c (scm_cmp_function): Choose subr2less for scm_tc7_subr_2o;
7837 (subr2oless): Removed.
7838 (scm_restricted_vector_sort_x): Use scm_return_first to keep the
7839 vector GC protected.
7841 * eval.c (check_map_args): Use scm_out_of_range_pos instead of
7844 2002-11-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
7846 * evalext.[ch] (scm_m_undefine, undefine): Deprecated.
7848 2002-11-17 Mikael Djurfeldt <mdj@linnaeus>
7850 * debug.c (scm_make_iloc): Added missing "return".
7852 2002-11-17 Marius Vollmer <mvo@zagadka.ping.de>

8362 unsigned numbers for computing minimum heap increment. This
8363 prevents weird results when a a negative minimum increment is
8366 2002-08-24 Marius Vollmer <mvo@zagadka.ping.de>
8368 * gc_os_dep.c: When we have __libc_stack_end, use that directly
8369 instead of the old tricks.
8371 * guile-snarf.in: Do not expect the input file to be the first
8372 argument after the optional "-o" option, just pass everything to
8373 the pre-processor without extracting the input file name.
8375 2002-08-23 Han-Wen Nienhuys <hanwen@cs.uu.nl>
8377 * gc-segment.c (scm_i_get_new_heap_segment): Oops. We want segment
8378 length *at* least SCM_MIN_HEAP_SEG_SIZE, not at most.
8380 2002-08-22 Han-Wen Nienhuys <hanwen@cs.uu.nl>
8382 * gc.h, gc.c: make scm_cells_allocated unsigned again. Thanks to
8383 Bill Schottstaedt for the bug report
8385 2002-08-20 Marius Vollmer <mvo@zagadka.ping.de>
8387 * print.c (scm_iprin1): Print primitives generics always as
8388 "primitive-generic" even when they have no primitive methods yet.
8390 2002-08-17 Gary Houston <ghouston@arglist.com>
8392 * coop.c (coop_create): removed bogus 2nd argument in scm_malloc
8395 2002-08-17 Han-Wen Nienhuys <hanwen@cs.uu.nl>
8397 * ports.c (scm_add_to_port_table): small bugfix.
8399 * mallocs.c (scm_malloc_obj): use scm_gc_malloc in stead of
8402 * gc-segment.c (scm_i_get_new_heap_segment): remove cluster cruft:
8403 only use SCM_MIN_HEAP_SEG_SIZE.
8405 * ports.c (scm_add_to_port_table): add backwards compatibility
8408 * ports.h: use scm_i_ prefix for port table and port table size.
8410 2002-08-15 Mikael Djurfeldt <mdj@linnaeus>
8412 * vports.c (scm_make_soft_port): Initialize pt variable.
8414 2002-08-13 Marius Vollmer <mvo@zagadka.ping.de>
8416 * strports.h (scm_c_eval_string_in_module,
8417 scm_eval_string_in_module): New prototypes.
8418 * strports.c (scm_eval_string_in_module): New, but use
8419 "eval-string" as the Scheme name and make second parameter
8421 (scm_eval_string): Implement using scm_eval_string_in_module.
8422 (scm_c_eval_string_in_module): New.
8423 Thanks to Ralf Mattes for the suggestion!
8425 2002-08-09 Han-Wen Nienhuys <hanwen@cs.uu.nl>
8427 * gc-card.c ("sweep_card"): remove SCM_MISC_ERROR messages: print
8430 * gc-mark.c ("scm_gc_mark_dependencies"): idem.
8432 * ports.c ("scm_new_port_table_entry"): return a boxed SCM in
8433 stead of scm_t_port*. The function now takes a tag argument.
8435 2002-08-08 Han-Wen Nienhuys <hanwen@cs.uu.nl>
8437 * gc.h: add scm_debug_cells_gc_interval to public interface
8439 * gc-card.c ("sweep_card"): set scm_gc_running while sweeping.
8441 * gc.c (scm_i_expensive_validation_check): separate expensive
8442 validation checks from cheap ones.
8444 2002-08-06 Han-Wen Nienhuys <hanwen@cs.uu.nl>
8446 * read.c (scm_input_error): new function: give meaningful error
8447 messages, and throw read-error
8449 * gc-malloc.c (scm_calloc): add scm_calloc.
8451 2002-08-05 Han-Wen Nienhuys <hanwen@cs.uu.nl>
8453 * tags.h: remove GC bits documentation from the tags table.
8455 * read.c (INPUT_ERROR): Prepare for file:line:column error
8456 messages for errors in scm_lreadr() and friends.
8458 2002-08-04 Han-Wen Nienhuys <hanwen@cs.uu.nl>
8460 * gc-malloc.c (scm_malloc): use scm_realloc() (simplifies
8462 (scm_gc_calloc): new function
8464 2002-08-04 Han-Wen Nienhuys <hanwen@cs.uu.nl>
8466 * ports.c (scm_new_port_table_entry): init port entry to 0
8469 * ports.c (scm_new_port_table_entry): change function from
8470 scm_add_to_port_table. This prevents cells with null-pointers from
8471 being exposed to GC.
8473 * vports.c (scm_make_soft_port) strports.c (scm_mkstrport),
8474 fports.c (scm_fdes_to_port): Use scm_new_port_table_entry().
8476 * gc.c (scm_gc_stats): add cell-yield and malloc-yield statistic
8479 * numbers.c (big2str): return "0" for 0 iso. ""
8481 * gc-segment.c, gc-malloc.c gc-mark.c, gc-freelist.c, gc-card.c,
8482 private-gc.h: new file
8484 * gc.c: completely revised and cleaned up the GC. It now uses lazy
8485 sweeping. More documentation in workbook/newgc.text
8487 2002-07-25 Marius Vollmer <marius.vollmer@uni-dortmund.de>
8489 * random.c (rstate_free): Return zero.
8491 2002-07-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
8493 * environments.c (remove_key_from_alist): Removed.
8495 (obarray_remove): Simplified.
8497 2002-07-24 Stefan Jahn <stefan@lkcc.org>
8499 * continuations.h: ia64: Include <signal.h> before
8502 2002-07-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
8504 * modules.c (scm_sym2var): Don't compare SCM values with ==.
8506 2002-07-21 Han-Wen Nienhuys <hanwen@cs.uu.nl>
8508 * goops.c (scm_compute_applicable_methods): use
8509 scm_remember_upto_here_1 iso scm_remember_upto_here
8511 * macros.c: include deprecation.h
8513 * vectors.c (scm_vector_move_right_x): remove side effect in
8515 (scm_vector_move_left_x): idem.
8517 * net_db.c, posix.c, socket.c: variable naming: change ans to
8520 * sort.c (scm_merge_vector_x): accept vector as argument
8521 iso. SCM*. This is needed for full GC correctness.
8523 * gc.h: undo previous undocumented changes related to #ifdef
8526 2002-07-20 Han-Wen Nienhuys <hanwen@cs.uu.nl>
8528 * *.c: add space after commas everywhere.
8530 * *.c: use SCM_VECTOR_SET everywhere, where a vector is written.
8531 Document cases where SCM_WRITABLE_VELTS() is used.
8533 * vectors.h (SCM_VELTS): prepare for write barrier, and let
8534 SCM_VELTS() return a const pointer
8535 (SCM_VECTOR_SET): add macro.
8537 2002-07-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
8539 * eval.c (SCM_CEVAL), macros.c (macro_print, scm_makmacro,
8540 scm_sym_macro, scm_macro_type), macros.h (scm_makmacro):
8541 Deprecated the special kind of built-in dynamic syntax transformer
8542 that was inaccurately named "macro". Note: The built-in syntax
8543 transformers that are named "mmacro" or "memoizing-macro" still
8544 exist, and it is these which come much closer to what one would
8547 2002-07-13 Neil Jerram <neil@ossau.uklinux.net>
8549 * eval.c (unmemocopy): Fix for
8550 1001-local-eval-error-backtrace-segfaults (unmemoization crash
8551 with internal definitions and local-eval).
8553 2002-07-12 Gary Houston <ghouston@arglist.com>
8555 * dynl.c: Don't define stub procedures if DYNAMIC_LINKING is not
8556 defined. They don't do anything useful, especially since the
8557 only case where DYNAMIC_LINKING is undefined seems to be
8558 when --with-modules=no is given to configure, which is basically
8559 requesting that the "dynamic linking module" be omitted.
8561 * Makefile.am (libguile_la_SOURCES): move dynl.c from
8562 libguile_la_SOURCES to EXTRA_libguile_la_SOURCES.
8564 * extensions.c (load_extension): check DYNAMIC_LINKING for
8566 * init.c (scm_init_guile_1): check DYNAMIC_LINKING for
8567 scm_init_dynamic_linking.
8569 2002-07-10 Marius Vollmer <mvo@zagadka.ping.de>
8571 * guile.c, iselect.h, net_db.c, posix.c, socket.c: No need to
8572 check for Cygwin when including <winsock2.h>, this is already
8573 check for by configure. Thus, revert change from 2002-07-07.
8575 2002-07-10 Gary Houston <ghouston@arglist.com>
8577 * eq.c: include <string.h>
8578 * dynl.c: docstring editing.
8580 2002-07-09 Gary Houston <ghouston@arglist.com>
8582 * dynl.c (scm_dynamic_call): docstring editing.
8584 2002-07-08 Rob Browning <rlb@defaultvalue.org>
8586 * gc_os_dep.c: HURD fixes.
8588 2002-07-07 Marius Vollmer <mvo@zagadka.ping.de>
8590 Crosscompiling and Cygwin fixes by Jan Nieuwenhuizen. Thanks!
8592 * Makefile.am: Override default rule for c-tokenize.$(OBJECT);
8593 this should be compiled for BUILD host.
8594 Override default rule for
8595 guile_filter_doc_snarfage$(EEXECT); this should run on BUILD host.
8596 Add missing $(EXEEXT) to guile_filter_doc_snarfage invocation.
8597 (snarf2checkedtexi): Use GUILE_FOR_BUILD instead of preinstguile.
8599 * guile.c, iselect.h, net_db.c, posix.c, socket.c: Do not include
8600 <winsock2.h> on Cygwin even when we have it.
8602 2002-07-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
8604 * __scm.h (SCM_CAUTIOUS), eval.c (scm_eval_args, deval_args,
8605 SCM_CEVAL): Removed compile time option SCM_CAUTIOUS to clean up
8606 the code. Full number of arguments checking of closures is
8607 mandatory now. However, the option to disable the checking has
8608 most probably not been used anyway.
8610 2002-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
8612 * __scm.h (SCM_RECKLESS), backtrace.c (SCM_ASSERT), debug.c
8613 (scm_debug_options), eval.c (scm_lookupcar, scm_lookupcar1,
8614 scm_badargsp, SCM_CEVAL, SCM_APPLY, scm_map, scm_for_each),
8615 feature.c (scm_init_feature), gsubr.c (scm_gsubr_apply), numbers.c
8616 (scm_logand, scm_logior, scm_logxor, scm_i_dbl2big), srcprop.c
8617 (scm_source_properties, scm_set_source_properties_x,
8618 scm_source_property): Removed compile time option SCM_RECKLESS to
8619 clean up the code. Full number of arguments checking of closures
8620 is mandatory now. However, the option to disable the checking has
8621 most probably not been used anyway.
8623 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
8624 scm_source_property): Use !SCM_CONSP instead of SCM_NCONSP.
8626 2002-06-30 Gary Houston <ghouston@arglist.com>
8628 * dynl.c: Removed all SCM_DEFER_INTS/SCM_ALLOW_INTS, which won't
8629 do anything useful. Added a comment about need for a mutex if
8630 pre-emptive threading is supported.
8632 * posix.c (scm_convert_exec_args), dynl.c
8633 (scm_make_argv_from_stringlist): static procs: 1) renamed both to
8634 allocate_string_pointers. 2) simplified: don't reallocate the
8635 strings, just make an array of pointers 3) avoid memory leaks on
8636 error 4) let the procedure report errors in its own name.
8637 Consequences: 1) the procedures now assume that SCM strings are
8638 nul-terminated, which should always be the case. 2) Since strings
8639 are not reallocated, it's now possible for strings passed to
8640 dynamic-args-call to be mutated.
8642 2002-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
8644 * __scm.h, eval.c, eval.h: Removed compile time option
8645 MEMOIZE_LOCALS to clean up the code. Now, caching of local
8646 variable positions during memoization is mandatory. However, the
8647 option to disable the caching has most probably not been used
8650 2002-06-18 Marius Vollmer <mvo@zagadka.ping.de>
8652 * print.c (scm_simple_format): Print missing part of format before
8653 ~% control. Thanks to Daniel Skarda!
8655 2002-06-01 Marius Vollmer <mvo@zagadka.ping.de>
8657 * mkstemp.c: Added exception notice to license statement.
8659 2002-05-22 Marius Vollmer <mvo@zagadka.ping.de>
8661 * numbers.c (mem2ureal): When returning an inexact zero, make sure
8662 it is represented as a floating point value so that we can change
8665 From John W. Eaton <jwe@bevo.che.wisc.edu>
8667 * numbers.c (idbl2str): Don't omit sign when printing negative zero.
8669 2002-05-14 Thien-Thi Nguyen <ttn@giblet.glug.org>
8671 * gc_os_dep.c: For I386/OPENBSD, allow for `__i386__'
8672 in addition to `i386'. Thanks to Dale P. Smith.
8674 2002-05-08 Marius Vollmer <mvo@zagadka.ping.de>
8676 * eq.c (real_eqv): New.
8677 (scm_eqv_p): Use it when comparing reals and complexes.
8679 * numbers.c: Include <string.h>, for strncmp.
8680 (mem2complex): Do not create negative NaNs.
8681 (scm_leq_p, scm_geq_p): Explicitely return #f when comparing a
8683 (scm_inexact_to_exact): Signal error when converting a NaN.
8685 2002-05-06 Marius Vollmer <mvo@zagadka.ping.de>
8687 * posix.c (scm_putenv): Handle removing variables explicitely by
8692 * numbers.h: Conditionally include floatingpoint.h, ieeefp.h, and
8693 nan.h. Provide declarations for scm_inf_p, scm_nan_p, scn_inf,
8695 * numbers.c: [SCO && ! HAVE_ISNAN] (isnan): New function.
8696 [SCO && ! HAVE_ISINF] (isinf): New function.
8697 (xisinf, xisnan): New functions.
8699 (isfinite): Define in terms of xisinf.
8700 (scm_inf_p, scm_nan_p): New functions.
8701 (guile_Inf, guile_NaN): New file-scope vars.
8702 (guile_ieee_init): New function.
8703 (scm_inf, scm_nan): New functions.
8704 (idbl2str): Handle Inf and NaN. Remove funny label and
8705 corresponding gotos.
8706 (ALLOW_DIVIDE_BY_ZERO): New macro.
8707 (scm_divide): Allow division by zero to occur if
8708 ALLOW_DIVIDE_BY_ZERO is defined.
8709 Handle bignums and ints as special cases.
8711 Additional stuff by me:
8713 numbers.c (mem2ureal): Recognize "inf.0" and "nan.xxx".
8714 (scm_even_p, scm_odd_p): Treat infinity as even and odd.
8715 (iflo2str): Don't output a '+' for negative numbers or for Inf and
8716 NaN. They will provide their own sign.
8717 (scm_divide): Only allow divides by inexact zeros. Dividing by
8718 exact zeros still signals an errors.
8720 2002-04-22 Thien-Thi Nguyen <ttn@giblet.glug.org>
8722 * goops.h (scm_slot_exists_p): Rename from scm_slots_exists_p.
8723 * goops.c (scm_slot_exists_p): Rename from scm_slots_exists_p.
8724 (scm_slot_exists_p): Rename from scm_slots_exists_p.
8725 Thanks to Andreas Rottmann.
8727 2002-04-20 Gary Houston <ghouston@arglist.com>
8729 * removal of unused fields in root state (thanks to Christopher
8730 Cramer for pointing out the disuse.)
8731 * root.h (scm_root_state): removed def_inp, def_outp, def_errp.
8732 (scm_def_inp, scm_def_outp, scm_def_errp): removed.
8734 * root.c (root_mark): don't mark them.
8735 (scm_make_root): don't set them to #f.
8736 * init.c (scm_init_standard_ports): don't initialise with the
8739 2002-04-17 Marius Vollmer <mvo@zagadka.ping.de>
8741 * Makefile.am (EXTRA_DIST): Added cpp_err_symbols.c and
8744 2002-04-16 Marius Vollmer <mvo@zagadka.ping.de>
8746 * guile-snarf.in: Do not clean input file. This would write to
8747 the $(srcdir) during a VPATH build, which is not allowed. It also
8748 isn't needed since it only works when an output filename has been
8749 specified and in that case we don't need to clean the input file
8750 because the output file will already exist.
8752 2002-03-31 Marius Vollmer <mvo@zagadka.ping.de>
8754 * guile-snarf: Install the trap for removing $cleanfile only when
8755 the value of $cleanfile is actually known.
8757 2002-04-10 Rob Browning <rlb@defaultvalue.org>
8759 * .cvsignore: add versiondat.h and *.c.clean.c.
8761 2002-03-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
8763 * srcprop.[ch] (scm_c_source_property_breakpoint_p): New
8764 function, replaces macro SRCBRKP.
8766 (SRCBRKP): Deprecated.
8768 * eval.c (SCM_CEVAL): Replaced use of SRCBRKP by call to
8769 scm_c_source_property_breakpoint_p. Removed some use of arg1 as
8772 2002-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
8774 * debug.h, eval.c: Deprecated CHECK_ENTRY, CHECK_APPLY and
8775 CHECK_EXIT and removed all references to them.
8777 2002-03-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
8779 * debug.h (scm_ready_p, debug_print): Removed declarations.
8781 * eval.c (EVALCELLCAR): Removed.
8783 (SCM_CEVAL): Eliminated label loopnoap. Removed side-effecting
8784 operation from condition.
8786 2002-03-24 Marius Vollmer <mvo@zagadka.ping.de>
8788 * guile-snarf.in: When the output filename is "-", write to
8789 stdout. When no "-o" option is given, use "-" as the output
8790 filename (i.e., stdout). Only 'clean' the inputfile or remove the
8791 output file on error when the output file name is not "-". Define
8792 the preprocessor macro SCM_MAGIC_SNARFER while snarfing.
8794 * Makefile.am (.c.x): Pass "-o $@" to guile-snarf.
8796 2002-03-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
8798 * eval.c (SCM_CEVAL, SCM_APPLY): Eliminated labels wrongnumargs
8799 and the corresponding goto statements. Removed redundant code.
8801 2002-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
8803 * eval.c (SCM_CEVAL): Minimized scope of variable arg2.
8804 Eliminated redundant SCM_IMP check. Exlined call to EVALCAR.
8805 Re-enabled handing of rpsubrs and asubrs.
8807 2002-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
8809 * eval.c (SIDEVAL): Removed.
8811 (SCM_CEVAL): Minimized scope of variable orig_sym. Eliminated
8812 goto-labels cdrxnoap, cdrxbegin and nontoplevel_cdrxnoap. Changed
8813 argument checking order for set! to locals, variables and symbols.
8814 Improvements to control structure. Removed some uses of arg1 and
8815 arg2 as temporary variables.
8817 2002-03-15 Thien-Thi Nguyen <ttn@giblet.glug.org>
8819 * guile-snarf.in: Remove "--compat=1.4" support.
8820 Add "-d" and "-D" support.
8822 (deprecated_list): New var.
8823 (compat_mode_clean_xxx): Delete.
8824 (grep_deprecated): New func.
8825 ("main"): If "-d" or "-D", call `grep_deprecated'.
8827 2002-03-15 Neil Jerram <neil@ossau.uklinux.net>
8829 * hooks.h: Change scm_t_c_hookype_t everywhere to
8834 * strings.c (scm_string_p): Change unnecessary `iff' to `if'.
8836 * ports.c (scm_sys_make_void_port): Use `@file'.
8838 * numbers.c (scm_number_p, scm_real_p): Use `otherwise' rather
8841 * macros.c (scm_makmacro): Don't say that the form replaces its
8842 source, because it doesn't.
8843 (scm_makmmacro): Clarify difference between this and scm_makmacro.
8845 * backtrace.c (scm_display_error), filesys.c (scm_umask,
8846 scm_select, scm_basename), goops.c (scm_method_generic_function),
8847 numbers.c (scm_integer_length), posix.c (scm_getgroups, scm_execl,
8848 scm_setlocale, scm_flock), socket.c (scm_shutdown): Correct
8851 * debug.c (scm_debug_options), eval.c
8852 (scm_eval_options_interface), read.c (scm_read_options): Change
8853 incorrect @var in docstring to @code.
8855 2002-03-14 Marius Vollmer <mvo@zagadka.ping.de>
8857 * unif.c (singp): Use SCM_REALP instead of SCM_SLOPPY_REALP.
8859 * snarf.h (SCM_SNARF_INIT): Add "^:^" after code so that
8860 guile-snarf can remove trailing non-init code.
8862 * guile-snarf.in (modern_snarf): Remove everything following and
8863 including "^:^" from the output.
8865 2002-03-14 Dirk Herrmann <D.Herrmann@tu-bs.de>
8867 * eval.c (SCM_CEVAL), srcprop.h (SRCBRKP): Eliminated union 't'.
8869 * eval.c (SCM_CEVAL): Exlined call to EVALCAR.
8871 2002-03-13 Thien-Thi Nguyen <ttn@giblet.glug.org>
8873 * guile-snarf.in: Update copyright.
8874 Rewrite to internalize error handling.
8875 Add "--compat=1.4" handling.
8878 * Makefile.am (libpath.h): Use @top_srcdir_absolute@.
8879 (snarfcppopts): New var.
8880 (.c.x): Use $(snarfcppopts). Rework guile-snarf usage.
8881 (.c.doc): Use $(snarfcppopts).
8883 * alist.c, arbiters.c, async.c, backtrace.c, boolean.c, chars.c,
8884 continuations.c, debug-malloc.c, debug.c, deprecation.c, dynl.c,
8885 dynwind.c, environments.c, eq.c, error.c, eval.c, evalext.c,

8898 2002-03-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
8900 * eval.c (SCM_CEVAL): Got rid of the last reference to t.lloc.
8901 The next step will be to remove the union 't' and simplify the
8902 code of SCM_CEVAL that way.

8915 potential overflow problems. Thanks to John W Eaton!
8917 * strop.c (string_capitalize_x): Treat characters as unsigned so
8918 that 8-bit chars work. Thanks to David Pirotte!
8920 2002-03-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
8922 * eval.c (SCM_CEVAL): Cleaned up the handling of 'slot-ref',
8923 'slot-set!' and 'nil-cond'. Removed some uses of t.arg1, arg2 and
8924 proc as temporary variables. Introduced temporary variables with
8925 hopefully descriptive names for clarification. Replaced SCM_N?IMP
8926 by a more explicit predicate in some places.

8931 Added lots of comments regarding the implementation of #@dispatch.
8932 Changed intra-procedure communication to use t.arg1 instead of
8933 arg2. Removed some uses of t.arg1, t.lloc and proc as temporary
8934 variables. Introduced temporary variables with hopefully
8935 descriptive names for clarification. Replaced SCM_N?IMP by a more
8936 explicit predicate in some places. Use SCM_INSTANCE_HASH instead
8937 of computing the expression explicitly. Eliminate now unused
8938 label nontoplevel_cdrxbegin.

8957 of SCM_MAX_FRAME_SIZE as a bit mask; it isn't used like this.
8959 * eval.c (SCM_CEVAL): Don't store scm_debug_eframe_size in
8960 debug.status. It isn't needed, and it can overflow the bits
8961 reserved for it (which may lead to a segv or a GC abort).
8963 2002-03-02 Dirk Herrmann <D.Herrmann@tu-bs.de>
8965 * eval.c (SCM_CEVAL): Cleaned up the handling of 'apply'. Removed

8978 'letrec' and 'set*': Removed some uses of t.arg1, t.lloc and proc
8979 as temporary variables. Removed side-effecting operations from
8980 conditions and macro calls. Introduced temporary variables with
8981 hopefully descriptive names for clarification. Replaced SCM_N?IMP
8982 by a more explicit predicate in some places. Removed code that
8983 was conditionally compiled if SICP was defined - which it never
8986 2002-03-02 Dirk Herrmann <D.Herrmann@tu-bs.de>
8988 * eval.c (SCM_CEVAL): Cleaned up the handling of 'cons' and 'do':

8991 Introduced temporary variables with hopefully descriptive names
8992 for clarification. Replaced SCM_N?IMP by a more explicit
8993 predicate in some places.

9427 * numbers.c (scm_divide): Fix more division by zero errors.
9429 2001-11-21 Gary Houston <ghouston@arglist.com>
9431 * Makefile.am (OMIT_DEPENDENCIES): removed, since it seems to be
9432 obsolete. autogen.sh says:
9433 invalid unused variable name: `OMIT_DEPENDENCIES'
9435 2001-11-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
9437 * numbers.c (scm_divide): Fix (/ 0). Thanks to Keith Wright for

9457 native M$-Windows compiler.
9459 2001-11-20 Marius Vollmer <mvo@zagadka.ping.de>
9461 * modules.c (scm_c_export): Do nothing when the first argument is

9481 (SCM_MICRO_VERSION): renamed from SCM_GUILE_MICRO_VERSION.
9483 2001-11-18 Neil Jerram <neil@ossau.uklinux.net>
9485 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
9486 Rewrite docstrings without reference to substring-move-left/right,
9487 since the latter no longer exist.
9489 2001-11-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
9491 * eval.c: Removed bogus comment about acros.
9493 (scm_unmemocar): Use !SCM_CONSP instead of SCM_IMP.
9494 Minimize scope of local variable. Eliminate dependency on
9495 macro DEBUG_EXTENSIONS.
9497 (s_splicing): New error message string.
9499 (scm_m_body): Issue 'bad body' message rather than 'missing
9500 expression' message.
9502 (scm_m_quote): Eliminate unnecessary copying.
9504 (scm_m_lambda, scm_m_letstar, scm_m_letrec, scm_m_let): Leave the
9505 checking of the body to scm_m_body.
9507 (scm_m_do): Move comment to function header. Rename arg1 to
9508 binding. Made the code a bit easier to read.
9512 (iqq): Added a comment. Changed the depth parameter to
9513 unsigned. Use size_t for vector lengths. Make sure vector object
9514 is gc protected as long as its contents are read. Add some syntax
9515 checks. Get rid of unnecessary SCM_IMP test. Clean up the
9516 control structure a bit.
9518 (scm_m_delay): Added comment about the implementation of
9521 (scm_m_define): Add comment about guile's currying define
9522 syntax. Renamed 'proc' to 'name'. Eliminate dependency on macro
9523 DEBUG_EXTENSIONS. Simplified code a bit. Eliminate SICP code.
9525 (scm_m_letrec1): Removed. Part of the functionality is taken
9526 over by the new function 'transform_bindings'.
9528 (transform_bindings): New function. Takes over some of the
9529 functionality of removed function 'scm_m_letrec1', namely to split
9530 a list of bindings into a reversed list of variables and a list of
9533 (scm_m_letrec): Call 'transform_bindings'.
9535 (scm_m_let): Minimized scope of local variables. Renamed 'proc'
9536 to 'temp' and 'arg1' to 'binding'. Eliminated redundant SCM_NIMP
9537 test. Use 'transform_bindings'. Fixed scoping error with named
9538 let (Thanks to Aubrey Jaffer for reporting the bug and to Neil
9539 Jerram for suggesting the fix). Cleaned up the control structure
9542 (scm_m_expand_body): Use 'transform_bindings'. Eliminated
9543 unnecessary consing. Eliminated unnecessary
9544 SCM_DEFER/ALLOW_INTS.
9546 (SCM_CEVAL): Un-obfuscated some loops.
9548 2001-11-16 Neil Jerram <neil@ossau.uklinux.net>
9550 * gc.h (scm_unhash_name): Old declaration removed.
9552 * eval.c (s_scm_eval): Change @var{primitive-eval} to
9553 @code{primitive-eval}.
9555 * feature.c, vectors.c, net_db.c, unif.c, weaks.c, struct.c,
9556 version.c, alist.c, ports.c, ramap.c, unif.c, strings.c, list.c:
9557 Change @deffnx lines in docstrings to say {Scheme Procedure}
9558 rather than primitive or procedure.
9560 * posix.c (scm_execl), filesys.c (scm_close), unif.c
9561 (scm_array_set_x, scm_array_contents, scm_uniform_array_read_x,
9562 scm_bit_set_star_x, scm_bit_invert_x), ramap.c (scm_array_fill_x,
9563 scm_array_for_each, scm_array_index_map_x), vectors.c (scm_vector,
9564 scm_make_vector, scm_vector_to_list, scm_vector_fill_x), strop.c
9565 (scm_string_split, scm_string_ci_to_symbol), strings.c
9566 (scm_string_p), sort.c (scm_merge), print.c (scm_newline),
9567 macros.c (scm_macro_type), alist.c (scm_acons, scm_assq):
9568 Docstring fixes and improvements reflecting edits that have been
9569 made in the reference manual source.
9571 * objprop.c (scm_object_properties, scm_set_object_properties_x,
9572 scm_object_property, scm_set_object_property_x): Remove invalid
9573 @deffnx lines for corresponding procedure property primitives.
9575 These changes add a @deffnx C function declaration and function
9576 index entries for each Guile primitive to the copy of the doc
9577 snarf output that is used for reference manual synchronization.
9578 Online help is unchanged.
9580 * snarf.h (SCM_SNARF_DOCS): Output primitive's C function name.
9581 (SCM_DEFINE, SCM_DEFINE1, SCM_REGISTER_PROC): Supply to C function
9582 name to SCM_SNARF_DOCS.
9584 * guile-snarf-docs-texi.in: Pass the shell script's arguments into
9585 snarf-check-and-output-texi.
9587 * Makefile.am (guile-procedures.texi): New rule.
9588 (BUILT_SOURCES, guile.texi, guile-procedures.txt, CLEANFILES):
9589 Changed so that the last stage of doc snarfing is now performed
9590 twice, once to produce guile-procedures.txt for online help, and
9591 once to produce guile.texi for reference manual synchronization.
9593 2001-11-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
9595 * eval.c (RETURN): Wrap in do{}while(0) in order to make it
9596 safely usable as a single statement followed by a ';', for example
9599 (SCM_CEVAL, SCM_APPLY): Clean up code using 'RETURN'.
9601 2001-11-13 Neil Jerram <neil@ossau.uklinux.net>
9603 * random.c (scm_random_solid_sphere_x,
9604 scm_random_hollow_sphere_x): Correct "shere" typos.

9617 scm_substring_move_right_x): Removed.
9619 * __scm.h (HAVE_UINTPTR_T, HAVE_PTRDIFF_T, HAVE_LONG_LONG,
9620 HAVE_LONG_LONGS): Define to "1" when defining them, to mirror what
9623 2001-11-12 Marius Vollmer <mvo@zagadka.ping.de>
9625 * numbers.c: Document macros to define when including
9626 num2integral.i.c. MAX_VALUE and MIN_VALU are no longer used, we
9627 now rely on SIZEOF_ macros that have been figured out at
9630 * num2integral.i.c: Adapt to new interface.
9631 (NUM2INTEGRAL): Test whether a fixnum can be represented in the
9632 target type by casting it and checking whether it is still the
9633 same. Do not try to handle bignums for integral types that are
9634 smaller than fixnums. When handling bignums, collect the
9635 magnituse first into a unsigned type, and correctly check for
9637 (INTEGRAL2BIG): Do not use MIN_VALUE explicitely by observing that
9638 only -MIN_VALUE can still be negative of all negative numbers (in
9641 * tags.h (SIZEOF_SCM_T_BITS): Define it appropriately.
9643 * __scm.h: Define HAVE_UINTPTR_T, HAVE_PTRDIFF_T and
9644 HAVE_LONG_LONG depending on whether their size is non-zero.
9646 2001-11-11 Thien-Thi Nguyen <ttn@glug.org>
9648 * strop.c (scm_string_null_p): Docfix; nfc.
9649 Thanks to Scott Lenser.

9656 * unif.c (scm_uniform_array_write), ports.c
9657 (scm_current_output_port, scm_force_output), dynwind.c
9658 (scm_dynamic_wind), scmsigs.c (scm_setitimer, scm_getitimer),
9659 filesys.c (scm_open, scm_lstat), struct.c
9660 (scm_make_struct_layout), random.c (scm_random,
9661 scm_random_solid_sphere_x, scm_random_hollow_sphere_x, strop.c
9662 (scm_i_index): Remove superfluous whitespace from end of docstring

9667 scm_make_undefined_variable, scm_variable_p, scm_variable_set_x,
9668 scm_variable_bound_p), scmsigs.c (scm_setitimer, scm_getitimer),
9669 posix.c (scm_crypt), struct.c (scm_make_vtable_vtable), hashtab.c
9670 (scm_hash_fold), ports.c (scm_port_for_each): Remove superfluous
9671 newline at end of docstrings.
9673 * modules.c (scm_set_current_module): Add missing newline to
9676 2001-11-07 Stefan Jahn <stefan@lkcc.org>
9678 * win32-socket.[ch]: New files. Defines Winsock-API error codes
9679 and makes them available through Guile. That is because the
9680 Winsock-API does not store its errors in `errno' and thus cannot
9681 return error messages via `strerror (errno)'.
9683 * socket.c (scm_init_socket): Initialize `win32-socket' part
9684 here under M$-Windows.
9686 * numbers.h: Added missing declaration of
9687 `scm_sys_check_number_conversions()'.
9689 * error.c: Local definition of SCM_I_STRERROR and SCM_I_ERRNO
9690 and use in `(strerror)' and `(system-error)'.
9692 * Makefile.am (EXTRA_libguile_la_SOURCES): Added
9693 `win32-socket.[ch]' to extra source and header files.
9695 2001-11-06 Marius Vollmer <mvo@zagadka.ping.de>
9697 * script.c (scm_shell_usage, scm_compile_shell_switches): Prepend
9698 a call to turn-on-debugging when --debug has been given instead of
9699 turning it on directly. Also, handle new `--no-debug' option,
9700 which might suppress the call to turn-on-debugging.
9702 2001-11-05 Stefan Jahn <stefan@lkcc.org>
9704 * struct.c (s_scm_struct_vtable_p): Corrected docstring.
9706 2001-11-04 Stefan Jahn <stefan@lkcc.org>
9708 * Makefile.am (libguile_la_LIBADD): Added $(THREAD_LIBS_LOCAL)
9709 here (was at guile_LDADD) which describes the dependency
9710 correctly and allows a clean build on Win32.
9712 * __scm.h (SCM_API): Follow-up patch. Renamed __FOO__ macros
9715 * __scm.h: USE_DLL_IMPORT indicates the usage of the DLL
9716 import macros for external libraries (libcrypt, libqthreads,
9717 libreadline and libregex).
9719 * coop-defs.h: Include <winsock2.h> for `struct timeval'.
9721 * posix.c (flock): Added support for flock() in M$-Windows.
9723 * guile.c (SCM_IMPORT): Follow-up patch. Use SCM_IMPORT instead
9726 * fports.c (getflags): Differentiate reading and writing pipes
9729 * filesys.c (S_IS*): Redefine all of the S_IS*() macros for
9732 * coop.c (coop_condition_variable_timed_wait_mutex): Use
9733 conditionalized error code if `ETIMEDOUT' is not available.
9734 (scm_thread_usleep): Remove bogus declaration of `struct timeval
9737 * numbers.c (PTRDIFF_MIN): Moved this definition where it actually
9738 belongs. That is because NO_PREPRO_MAGIC gets undefined after
9739 each inclusion of `num2integral.i.c'.
9740 (SIZE_MAX): Define NO_PREPRO_MAGIC if SIZE_MAX is undefined.
9742 2001-11-03 Marius Vollmer <mvo@zagadka.ping.de>
9744 * eval.c (scm_m_begin): Allow `(begin)`, with no subforms.
9745 (SCM_CEVAL): Evaluate an empty `begin' to SCM_UNSPECIFIED.
9747 2001-11-02 Mikael Djurfeldt <mdj@linnaeus>
9749 * print.c (scm_iprin1): Mark print state as revealed when
9750 dispatching to generic write or display.
9752 * unif.c (scm_ra2contig): Fixed memory overwrite bug.
9754 2001-11-02 Marius Vollmer <mvo@zagadka.ping.de>
9756 Support for native Win32. Thanks to Stefan Jahn!
9758 * Makefile.am: Add win32-uname.c, win32-uname.h, win32-dirent.c
9759 and win32-dirent.h to extra source and header files. These
9760 include the uname() and the POSIX dirent interface implementation
9761 for M$-Windows. Put `-no-undefined' into LDFLAGS to support
9762 linkers which do not allow unresolved symbols inside shared
9763 libraries. Corrected `guile_filter_doc_snarfage$(EXEEXT)'
9766 * __scm.h: Defined SCM_API. This macro gets prepended to all
9767 function and data definitions which should be exported or imported
9768 in the resulting dynamic link library in the Win32 port.
9770 * __scm.h, alist.h, arbiters.h, async.h, backtrace.h, boolean.h,
9771 chars.h, continuations.h, coop-defs.h, coop-threads.h,
9772 debug-malloc.h, debug.h, deprecation.h, dynl.h, dynwind.h,

9783 tags.h, threads.h, throw.h, unif.h, values.h, variable.h, vectors.h,
9785 Prefixed each each exported symbol with SCM_API.
9787 * continuations.c: Added comment about the use of the extern
9788 declarations of {get,set}context() functions used in the ia64 port.
9790 * continuations.h, gc.c: `__libc_ia64_register_backing_store_base'
9791 is meant to be a `unsigned long *'.
9793 * filesys.c: Include `direct.h' if possible. Use local
9794 `win32-dirent.h' for the native M$-Windows port. Define S_IS*()
9795 macros for M$-Windows. Implementation of `fstat_Win32()' which is
9796 able to differentiate between sockets and other file descriptors.
9797 Use this function as wrapper in `scm_fstat()'. Fixed typo in
9800 * fports.c: Include `io.h' is possible. Put `*fp' into referring
9801 statement block in `scm_fport_buffer_add()'.
9802 Some corrections in `getflags()'.
9804 * gdb_interface.h (GDB_INTERFACE): Also support __CYGWIN__.
9806 * guile.c: Make sure to define __SCM_IMPORT__ for shared library
9807 build on Win32. Disable preloaded symbols on Win2 platforms.
9809 * ioext.c, ports.c: Include `io.h' is possible.
9811 * mkstemp.c: Include `process.h' is possible.
9813 * net_db.c: Disable extern declaration of `h_errno' for __CYGWIN__,
9815 Put `scm_return_entry()' into HAVE_GETSERVENT conditional.
9817 * posix.c: Remove unnecessary dirent includes and defines. Include
9818 local `win32-uname.h' for MinGW. Extern declaration of
9819 `mkstemp()' for systems where it does not exists. Make
9820 `getlogin()' available on M$-Windows.
9822 * scmsigs.c: Made `usleep()' avalable on MinGW.
9824 * stime.c: On M$-Windows `tzname[]' is known to be `_tzname[]'.
9826 * win32-dirent.c: Include "win32-dirent.h", not "dirent.h".
9828 * win32-uname.c: Include "win32-uname.h", not "uname.h".
9830 2001-10-28 Mikael Djurfeldt <mdj@linnaeus>
9832 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write):
9833 Don't apply scm_uniform_vector_length on arrays.
9835 2001-10-14 Dirk Herrmann <D.Herrmann@tu-bs.de>
9837 * eval.c (scm_lookupcar, scm_m_letstar, scm_m_do, iqq,
9838 scm_m_define, scm_m_letrec1, scm_m_let, scm_m_expand_body,
9839 scm_macroexp, unmemocopy, scm_eval_args, scm_deval_args,
9840 SCM_CEVAL, scm_map, scm_init_eval): When building lists, prefer
9841 scm_list_<n> over scm_cons[2]?.
9843 (scm_unmemocar, scm_m_cond, scm_m_letstar, scm_m_letrec1,
9844 scm_m_let, scm_m_atbind, unmemocopy, SCM_CEVAL, SCM_APPLY): Use
9845 SCM_C[AD][AD]R instead of explicit form.
9847 (scm_m_set_x, scm_m_cond, scm_m_letstar, scm_m_do): Reordered
9848 comparison parameters.
9850 (scm_m_case, scm_m_cond, scm_m_letstar, scm_m_do, SCM_CEVAL): Use
9851 !SCM_NULLP instead of SCM_NIMP.
9853 (scm_m_case): Don't copy the form. Renamed proc to clause and
9854 minimized its scope. Renamed x to clauses. Removed side
9855 effecting operation from macro call.
9857 (scm_m_cond): Don't copy the form. Renamed arg1 to clause and
9858 minimized its scope. Renamed x to clauses. Minimized the scope
9859 of variable 'len'. Make sure the else clause is treated specially
9860 even in case of '=>' occurences. Don't change the else to #t in
9861 order to be able to distinguish this case in the evaluator. Leave
9862 type checking of the recipient to the evaluator.
9864 (scm_c_improper_memq): Made the comment somewhat clearer.
9866 (scm_m_lambda): Renamed proc to formals. Removed unnecessary
9867 test for SCM_IM_LET at the place of the formal parameters.
9868 Simplified the formal parameter checking.
9870 (scm_m_letstar): Added Comment. Renamed proc to bindings.
9871 Renamed arg1 to binding and minimized its scope. Eliminated
9872 unnecessary consing.
9874 (scm_m_do): Renamed proc to bindings. Minimized the scope of
9877 (build_binding_list): New static function.
9879 (unmemocopy): Don't use SCM_TYP7 on pairs (it's unclean).
9880 Further, split up the 'letrec' unmemoizing code to the
9881 corresponding parts for 'do', 'let' and 'letrec', adding comments
9882 to each form. Cleanup the handling of the do form (This removes
9883 some *real* code :-).
9885 (SCM_CEVAL): Removed side effecting operation from macro call.
9886 Handle the 'else clause of the 'cond form specially - the symbol
9887 'else is not replaced with #t any more.
9889 2001-10-14 Gary Houston <ghouston@arglist.com>
9891 * version.c (scm_version): use sprintf instead of snprintf,
9892 for portability. thanks to Bill Schottstaedt.
9894 2001-10-14 Mikael Djurfeldt <mdj@linnaeus>
9896 * read.c (scm_lreadr): When user-defined hash procedure returns
9897 SCM_UNSPECIFIED: Fall back to standard handling instead of raising
9898 an exception. (This prevents parsing of uniform vectors from
9899 interfering with parsing of numbers.)
9901 2001-10-13 Marius Vollmer <mvo@zagadka.ping.de>
9903 * numbers.c: Set NO_PREPRO_MAGIC when defining our version of
9904 PTRDIFF_MIN. Thanks to Ken Raeburn.
9906 2001-10-07 Marius Vollmer <mvo@zagadka.ping.de>
9908 * Makefile.am (EXTRA_libguile_la_SOURCES): Added "mkstemp.c".
9910 * eval.c (scm_m_atbind): First try to find the variable without
9911 defining it locally; when it has not been found, define it
9914 * modules.c (module_variable): Pass over variables that exist but
9917 2001-10-06 Marius Vollmer <mvo@zagadka.ping.de>
9919 * backtrace.c (display_backtrace_file_and_line): Only use
9920 scm_basename when POSIX support is compiled in. Thanks to Chris
9923 2001-10-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
9925 * numbers.c (mem2uinteger): Return number read so far when coming
9926 across a hexdigit after having read a # or if not reading a hex
9927 value. This will enable the calling code to correctly handle
9928 forms like 1e2. (The background is, that the exponent markers d,
9929 e and f are also hexdigits.) Thanks to Mikael Djurfeldt for
9930 providing this patch.
9932 (mem2complex): Fix erroneous double-negation. Now, numbers like
9933 1-i will be read correctly.
9935 2001-10-12 Mikael Djurfeldt <mdj@linnaeus>
9937 * debug.c (scm_mem_to_proc): Fixed typo in previous change.
9939 * validate.h (SCM_VALIDATE_DOUBLE_DEF_COPY): New macro.
9941 2001-10-12 Dirk Herrmann <D.Herrmann@tu-bs.de>
9943 * print.c (scm_print_state_vtable, print_state_pool):
9944 Initialize. These variables are now registered as gc roots.
9946 (scm_current_pstate): Update documentation.
9948 (scm_current_pstate, scm_make_print_state, scm_free_print_state,
9949 scm_prin1, scm_init_print): print_state_pool is registered as a
9950 gc root and thus does not need to be protected by a surrounding
9953 (make_print_state): The car of print_state_pool no longer holds
9954 the scm_print_state_vtable.
9956 (scm_current_pstate, scm_make_print_state, print_circref,
9957 scm_iprin1, scm_prin1, scm_iprlist): Prefer !SCM_<foo> over
9960 (scm_prin1): When building lists, prefer scm_list_<n> over
9963 (scm_iprlist): Removed a redundant SCM_IMP test.
9965 (scm_simple_format): Use SCM_EQ_P to compare SCM values.
9967 2001-10-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
9969 * debug.c (scm_make_iloc): Prefer !SCM_<foo> over SCM_N<foo>.
9971 (scm_memcons, scm_mem_to_proc): When building lists, prefer
9972 scm_list_<n> over scm_cons[2]?.
9974 (scm_mem_to_proc): Prefer SCM_CONSP over SCM_NIMP.
9976 (scm_procedure_name): Use SCM_CADR instead of explicit form.
9978 (debugobj_print): Coerce scm_intprint arg 1 to long, not int.
9979 Thanks to Rob Browning for the patch (see log entry 2001-09-21) -
9980 for some reason his patch didn't make it into the cvs.
9982 2001-10-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
9984 * numbers.c (mem2decimal_from_point): Cleaned up the parsing a
9985 little bit - should even be somewhat more accurate now.
9987 2001-10-08 Rob Browning <rlb@defaultvalue.org>
9989 * gc.c: support ia64 register backing store.
9990 (SCM_MARK_BACKING_STORE): new macro.
9992 * continuations.h: support ia64 register backing store.
9993 (struct scm_t_contregs): add ia64 register backing store.
9995 * continuations.c: support ia64 register backing store.
9996 (continuation_mark): mark ia64 register backing store.
9997 (continuation_free): free ia64 register backing store.
9998 (scm_make_continuation): capture ia64 register backing store.
9999 (copy_stack_and_call): copy ia64 register backing store.
10001 2001-10-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
10003 * hashtab.c (scm_hash_fn_create_handle_x): The result of assoc_fn
10004 is known to be #f if no entry is found. Thus, use !SCM_FALSEP
10005 instead of SCM_NIMP to test for that case.
10007 * strings.h (SCM_SET_STRING_LENGTH): Cast the length to
10008 scm_t_bits instead of long.
10010 2001-10-06 Marius Vollmer <mvo@zagadka.ping.de>
10012 * tags.h (SCM_T_BITS_MAX, SCM_T_SIGNED_BITS_MAX,
10013 SCM_T_SIGNED_BITS_MIN): New.
10014 * numbers.h (SCM_MOST_POSITIVE_FIXNUM, SCM_MOST_NEGATIVE_FIXNUM):
10015 Use them to make these macros computable by the preprocessor.
10017 * num2integral.i.c (INTEGRAL2NUM): Let the preprocessor test
10018 whether the integral type fits in a fixnum, not the compiler.
10019 This removes a spurious compiler warning. Also, honor the
10020 NO_PREPRO_MAGIC flag to suppress any preprocessor tests. This is
10021 needed for `long long's.
10023 * numbers.c: Define NO_PREPRO_MAGOC when including
10024 num2integral.c.i for `long long' and `signed long long'.
10026 2001-10-06 Mikael Djurfeldt <mdj@linnaeus>
10028 These changes fixes a race condition in the Guile coop - pthread
10029 compatibility code.
10031 * coop.c (mother_awake_p): New variable.
10032 (coop_create): Set mother_awake_p before creating or signalling
10033 mother; wait until mother is going to sleep before returning.
10034 (mother): Reset mother_awake_p before going to sleep.
10036 2001-10-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
10038 * options.c (protected_objects, scm_init_options): The content of
10039 protected_objects is now protected from garbage collection using
10040 scm_gc_register_root instead of scm_permanent_object.
10042 (get_option_setting): New static function that computes an option
10043 setting as it was formerly done in the function scm_options.
10045 (get_documented_option_setting): New static function that
10046 returns option documentation as it was formerly done in the
10047 function scm_options. Note that documentation C strings are no
10048 longer precomputed into SCM objects. Instead, they are converted
10049 into SCM strings every time get_documented_option_setting is
10052 (change_option_setting): New static functions that modifies the
10053 option setting as it was formerly done in the function
10054 scm_options. The function is now exception safe, i. e. won't
10055 cause a memory leak when interrupted. Further, only non-immediate
10056 option values are added to the protection list.
10058 (scm_options): This function now has only the purpose to dispatch
10059 to to get_option_setting, get_documented_option_setting or
10060 change_option_setting, depending on the arguments given to
10063 (scm_init_opts): Don't convert documentation C strings into SCM
10064 strings. Further, don't protect any object values: They _must_
10065 be immediate values, otherwise there is no guarantee that they
10066 have not been collected before anyway.
10068 * options.[ch] (scm_t_option): Made type unsigned, name into a
10069 constant char* and val into a scm_t_bits type.
10071 (scm_options, scm_init_opts): The number of options is guaranteed
10072 to be larger or equal to zero. Thus, the type is changed to
10075 2001-10-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
10077 * num2integral.i.c (NUM2INTEGRAL): Eliminated some warnings about
10078 testing an unsigned value for being >= 0.
10080 2001-10-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
10082 * numbers.h: Removed old comment about using SCM_CAR to access
10085 (SCM_MOST_POSITIVE_FIXNUM, SCM_MOST_NEGATIVE_FIXNUM): Make sure
10086 the return value is signed. Thanks to Brian Crowder for the bug
10089 (SCM_SRS): Avoid unnecessary casting and don't unpack input
10090 values. With this patch, SCM_SRS can be safely used for other
10091 types than scm_t_signed_bits. However, it should still better be
10092 an internal macro and thus be renamed to SCM_I_SRS.
10094 (SCM_MAKINUM, SCM_INUM): Use proper casting.
10096 2001-10-03 Gary Houston <ghouston@arglist.com>
10098 * continuations.h, unif.h: in the descriptions of the bit patterns
10099 of the heap cells, make bit 0 the least significant.
10101 2001-09-25 Thien-Thi Nguyen <ttn@glug.org>
10103 * chars.h (SCM_MAKE_CHAR): Use `scm_t_bits' instead of `intptr_t'.
10104 Thanks to Golubev I. N.
10106 2001-09-25 Gary Houston <ghouston@arglist.com>
10108 * ports.c (scm_drain_input): extended the docstring. thanks to
10109 Alex Schroeder and Thien-Thi Nguyen.
10111 2001-09-23 Mikael Djurfeldt <mdj@linnaeus>
10113 * validate.h (SCM_NUM2FLOAT, SCM_NUM2DOUBLE,
10114 SCM_VALIDATE_FLOAT_COPY, SCM_VALIDATE_DOUBLE_COPY): New
10115 macros. (The NUM names might soon change.)
10117 * numbers.h: Added missing declarations.
10119 2001-09-22 Mikael Djurfeldt <mdj@linnaeus>
10121 * Makefile.am: Distribute num2float.i.c.
10123 * num2float.i.c: New file, multiply included by numbers.c, used
10124 to "templatize" the float <-> num conversion routines.
10126 * numbers.c: New functions: scm_num2float, scm_float2num,
10127 scm_num2double, scm_double2num.
10129 2001-09-21 Rob Browning <rlb@defaultvalue.org>
10131 * .cvsignore: really add version.h
10133 * strings.h (SCM_SET_STRING_LENGTH): coerce "l" to a long.
10134 Otherwise it fails on the alpha. However, we might rather choose
10135 this size conditionally.
10137 * numbers.c (scm_gcd): change "k" to a long from an int.
10138 Otherwise it fails on the alpha. However, we might rather choose
10139 this size conditionally.
10141 * error.c (scm_wta): coerce char* to intptr_t before int
10144 * debug.c (debugobj_print): coerce scm_intprint arg 1 to long, not
10147 * chars.h (SCM_MAKE_CHAR): coerce value to intptr_t.
10149 2001-09-20 Mikael Djurfeldt <mdj@linnaeus>
10151 * numbers.c (scm_integer_expt): Accept inexact integer in second
10152 argument. (Thanks to Bill Schottstaedt.)
10154 2001-09-20 Rob Browning <rlb@defaultvalue.org>
10156 * .cvsignore: add version.h
10158 * versiondat.h.in: removed (obsolete).
10160 * version.h.in: renamed from version.h.
10161 (SCM_GUILE_MAJOR_VERSION): new public macro.
10162 (SCM_GUILE_MINOR_VERSION): new public macro.
10163 (SCM_GUILE_MICRO_VERSION): new public macro.
10165 * version.h: renamed to version.h.in.
10168 (scm_major_version): support integer *_VERSION macros.
10169 (scm_minor_version): support integer *_VERSION macros.
10170 (scm_micro_version): support integer *_VERSION macros.
10171 (scm_version): support integer *_VERSION macros.
10173 2001-09-20 Mikael Djurfeldt <mdj@linnaeus>
10175 * error.c, error.h: Made error keys globally accessible.
10176 Applications might want to test for these or use them in a direct
10179 * num2integral.i.c (NUM2INTEGRAL): Report an error when these
10180 routines are passed an inexact. This change in behavior is
10181 motivated by concordance with R5RS: It is more common that a
10182 primitive doesn't want to accept an inexact for an exact.
10184 2001-09-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
10186 The following patch partially undoes my patch from 2001-06-30,
10187 where I added the function scm_gc_mark_cell_conservatively. The
10188 function is buggy, since it breaks guile during conservative
10189 marking if a pointer on the stack points directly into the list of
10190 free cells on the heap: With conservative cell marking this will
10191 cause the whole free list to be scanned and marked - boom!
10193 * gc.c (allocated_mark, MARK, heap_segment,
10194 scm_gc_mark_cell_conservatively, scm_init_storage), gc.h
10195 (scm_gc_mark_cell_conservatively): Remove function
10196 scm_gc_mark_cell_conservatively and update the corresponding
10197 comments and uses accordingly. Thanks to Christopher Cramer for
10198 the patch. (Minor corrections by me.)
10200 2001-09-15 Gary Houston <ghouston@arglist.com>
10202 * root.h (scm_root_state): removed the continuation_stack and
10203 continuation_stack_ptr members, which have no apparent purpose.
10204 (scm_continuation_stack, scm_continuation_stack_ptr): #defines
10207 * root.c (root_mark), init.c (restart_stack, start_stack), gc
10208 (scm_igc): remove all references to contination_stack and
10209 continuation_stack_ptr, avoiding allocation of a vector and
10210 useless processing during gc.
10212 2001-09-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
10214 * guardians.c (tconc_t, t_tconc): Renamed tconc_t to t_tconc.
10216 (TCONC_IN): Make sure that the cell word 0 is initialized last.
10218 (guardians_t, t_guardians): Renamed guardians_t to t_guardians.
10220 (GUARDIAN, GUARDIAN_DATA): Renamed GUARDIAN to GUARDIAN_DATA.
10222 (guardian_apply, scm_get_one_zombie, scm_make_guardian,
10223 mark_and_zombify): Prefer !SCM_<foo> over SCM_N<foo>.
10225 2001-09-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
10227 * guardians.c (mark_dependencies_in_tconc,
10228 whine_about_self_centered_zombies, scm_init_guardians): Register
10229 the static global variable `self_centered_zombies' via
10230 scm_gc_register_root, to make some cdr-ing unnecessary.
10232 2001-09-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
10234 * backtrace.c (display_backtrace_file,
10235 display_backtrace_file_and_line): Use SCM_EQ_P when comparing SCM
10236 values, use SCM_FALSEP when comparing SCM values against #f.
10237 Thanks to Rob Browning for the bug report.
10239 2001-09-12 Martin Baulig <martin@home-of-linux.org>
10241 * strings.[ch] (scm_str2string): New function.
10243 2001-09-06 Marius Vollmer <mvo@zagadka.ping.de>
10245 * gc.c (scm_done_free): Always subtract size from scm_mallocated
10246 when computing nm, even if it's negative.
10247 (scm_must_malloc): Abort on overflow of scm_mtrigger.
10248 (scm_must_realloc): Likewise.
10250 2001-09-01 Michael Livshin <mlivshin@bigfoot.com>
10252 * numbers.c (scm_sys_check_number_conversions): new function,
10253 defined if Guile is compiled in debugging mode. currently checks
10254 `scm_num2ulong', should check much much more.
10256 * num2integral.i.c (NUM2INTEGRAL): when converting a bignum to
10257 unsigned, ensure that it's positive. thanks to Martin Baulig!
10259 2001-08-31 Dirk Herrmann <D.Herrmann@tu-bs.de>
10261 * __scm.h: Added new section about compile time selectable
10264 (long_long, ulong_long, scm_sizet, SCM_WNA, SCM_OUTOFRANGE,
10265 SCM_NALLOC, SCM_HUP_SIGNAL, SCM_INT_SIGNAL, SCM_FPE_SIGNAL,

10267 SCM_TICK_SIGNAL, SCM_SIG_ORD, SCM_ORD_SIG, SCM_NUM_SIGS):
10270 * deprecation.c (scm_include_deprecated_features): Simplified.
10272 * eval.c (EVALCAR, unmemocopy), eval.h (SCM_XEVALCAR): Use
10273 `SCM_IMP' instead of `!SCM_CELLP´.
10275 * eval.c (unmemocopy): Eliminate redundant SCM_CELLP tests.
10276 Extract side-effecting operations from macros.
10278 (scm_init_eval): Don't initialize *top-level-lookup-closure*,
10279 scm_top_level_lookup_closure_var and scm_system_transformer.
10281 * gc.c (CELL_P): New local definition to replace SCM_CELLP.
10283 (heap_segment): Use CELL_P instead of SCM_CELLP.
10285 * init.c (start_stack): Don't initialize
10286 scm_top_level_lookup_closure_var and scm_system_transformer.
10288 * modules.c (scm_set_current_module): Don't access
10289 scm_top_level_lookup_closure_var and scm_system_transformer.
10291 (scm_sym2var): Don't call scm_variable_set_name_hint.
10293 (scm_post_boot_init_modules): Removed deprecated initializations.
10295 * print.c (scm_ipruk): Don't access cell contents of non cells.
10297 * strings.c (scm_string_set_x): All strings are writable.
10299 * strings.h (SCM_STRINGP): Use SCM_TYP7 to determine the string
10300 type. There is only one string type now.
10302 (SCM_STRING_COERCE_0TERMINATION_X): Deprecated.
10304 * tags.h: Remove comments about two different string types.
10306 (SCM_CELLP, SCM_NCELLP): Deprecated.
10308 * variable.c (make_variable): Remove code variant for vcells.
10310 * variable.h (SCM_VARIABLE_REF, SCM_VARIABLE_SET,
10311 SCM_VARIABLE_LOC): Remove code variant for vcells.
10313 * __scm.h, deprecation.[ch]: Renamed SCM_DEBUG_DEPRECATED to
10314 SCM_ENABLE_DEPRECATED with the logic reversed.
10316 * dynl.c (moddata, registered_mods), dynl.[ch]

10775 hold predefined symbols.
10777 (build_class_class_slots): Build the list using scm_list_n
10778 instead of cons. Also, slots are already created as lists, thus
10779 making a call to maplist unnecessary.

10815 (burnin, go_to_hell): Use SCM_STRUCT_DATA instead of the SCM_INST
10818 2001-07-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
10820 * fports.c (fport_print): Don't use SCM_C[AD]R for non pairs.

10863 2001-07-04 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
10865 * hooks.c (scm_make_hook, scm_add_hook_x),
10866 (scm_remove_hook_x, scm_reset_hook_x, scm_run_hook): Added return
10867 value info to the docstrings.
10869 2001-07-03 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
10871 Some more compatibility patches for Windows.
10873 * posix.c (getlogin): getlogin() implementation for Windows.

10880 * cpp_sig_symbols.in: Added SIGBREAK.
10882 2001-07-01 Marius Vollmer <mvo@zagadka.ping.de>
10884 * strports.c (scm_read_0str, scm_eval_0str): Call
10885 scm_c_read_string and scm_c_eval_string respectively, not
10886 themselves. Thanks to Dale P. Smith!
10888 2001-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
10890 * unif.c (scm_array_set_x): The variable args does not
10891 necessarily have to be a list. Further, got rid of a redundant
10894 2001-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
10896 * list.c (SCM_I_CONS): Make sure the cell type is initialized
10899 * gc.c (s_scm_map_free_list, scm_igc, scm_gc_sweep,
10900 init_heap_seg): Fixed signedness.
10902 (init_heap_seg): Replaced strange for-loop with a while loop.
10904 * weaks.h (WEAKSH, SCM_WEAKS_H): Rename <foo>H to SCM_<foo>_H.
10906 (SCM_WVECTP): Prefer !SCM_<pred> over SCM_N<pred>.
10908 The following patch adds conservative marking for the elements of
10909 free or allocated cells.
10911 * gc.c (allocated_mark, heap_segment): New static functions.
10913 (which_seg): Deleted, since the functionality is now provided by
10914 function heap_segment.
10916 (map_free_list): Use heap_segment instead of which_seg.
10918 (MARK): If cell debugging is disabled, mark free cells
10921 (scm_mark_locations, scm_cellp): Extracted the search for the
10922 heap segment of a SCM value into function heap_segment.
10924 (scm_init_storage): Allocated cells must be marked
10927 * gc.[ch] (scm_gc_mark_cell_conservatively): New function.
10929 The following patch changes the representation of weak vectors to
10930 double cells instead of using an extension of the vector's
10933 * gc.c (MARK): Use SCM_SET_WVECT_GC_CHAIN instead of assigning to
10934 the result of SCM_WVECT_GC_CHAIN.
10936 (scm_gc_sweep): Weak vectors don't have extra fields any more.
10938 * weaks.c (allocate_weak_vector): New static function. It does
10939 not patch any previously created vector object during the
10940 construction of a weak vector, and thus doesn't need to switch
10941 off interrupts during vector creation.
10943 (scm_make_weak_vector, scm_make_weak_key_hash_table,
10944 scm_make_weak_value_hash_table, scm_make_doubly_weak_hash_table):
10945 Use allocate_weak_vector to provide the new weak vector object.
10947 * weaks.h (SCM_WVECT_TYPE, SCM_SET_WVECT_TYPE,
10948 SCM_SET_WVECT_GC_CHAIN): New macros. The weak vector subtype is
10949 now stored in the double cell.
10951 (SCM_IS_WHVEC, SCM_IS_WHVEC_V, SCM_IS_WHVEC_B, SCM_IS_WHVEC_ANY):
10952 Use SCM_WVECT_TYPE.
10954 (SCM_WVECT_GC_CHAIN): The weak objects are now chained together
10955 using an entry of the double cell.
10957 2001-06-30 Thien-Thi Nguyen <ttn@revel.glug.org>
10959 * stamp-h.in: bye bye
10961 2001-06-30 Marius Vollmer <mvo@zagadka.ping.de>
10963 * gh_eval.c (gh_eval_str): Use scm_c_eval_string instead of
10966 * load.c, load.h (scm_c_primitive_load,
10967 scm_c_primitive_load_path): New.
10969 * strports.c, strports.h (scm_c_read_string): Renamed from
10970 scm_read_0str. Also, added "const" qualifier to argument.
10971 (scm_c_eval_string): Renamed from scm_eval_0str.

10982 scm_list_n): New functions.

10984 SCM_LIST6, SCM_LIST7, SCM_LIST8, SCM_LIST9, scm_listify): Deprecated.
10985 (lots of files): Use the new functions.
10987 * goops.c (CALL_GF1, CALL_GF2, CALL_GF3, CALL_GF4): Use scm_call_N.
10989 * strings.c: #include "libguile/deprecation.h".
10991 2001-06-27 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
10993 * read.c (scm_lreadr): When reading a hash token, check for a
10994 user-defined hash procedure first, so that overriding the builtin
10995 hash characters is possible (this was needed for implementing
10996 SRFI-4's read synax `f32(...)').
10998 * num2integral.i.c: Use scm_t_signed_bits instead of scm_t_bits,
10999 because the latter is unsigned now and breaks comparisons like
11000 (n < (scm_t_signed_bits)MIN_VALUE).
11002 2001-06-26 Neil Jerram <neil@ossau.uklinux.net>
11004 * eval.h, eval.c (scm_call_4): New function.
11006 * eval.c (SCM_APPLY, SCM_CEVAL, ENTER_APPLY): Call trap handlers
11007 directly rather than dispatching to them via scm_ithrow and a lazy
11010 * eval.c (scm_evaluator_trap_table), eval.h (SCM_ENTER_FRAME_HDLR,
11011 SCM_APPLY_FRAME_HDLR, SCM_EXIT_FRAME_HDLR): Add three new options
11012 for trap handler procedures.
11014 * debug.h (SCM_RESET_DEBUG_MODE): Add checks for trap handler
11015 procedures not being #f.
11017 2001-06-27 Michael Livshin <mlivshin@bigfoot.com>
11019 * Makefile.am (c-tokenize.c): add rule to generate it.
11020 (EXTRA_DIST): add c-tokenize.lex, so it gets distributed.
11022 filter-doc-snarfage.c: remove.
11024 2001-06-26 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
11026 * ports.c (scm_output_port_p): Use result of SCM_COERCE_OUTPORT.
11028 The following set of changes makes compiling Guile under various
11029 Windows compilers easier. Compilation under GNU systems should
11030 not be affected at all.
11032 Thanks to Stefan Jahn for all necessary information, patches and
11035 * posix.c: Conditialize getpwent, getgrent, kill, getppid, getuid,
11036 getpgrp, ttyname, primitive-fork and some header inclusion for
11039 * random.c: Define M_PI, if not predefined and use __int64 for
11040 LONG64 under Windows.

11053 * net_db.c: Do not declare errno under Windows.
11055 * iselect.h, inet_aton.c: Include socket library headers under
11058 * guile.c (inner_main): Under Windows, initialize socket library
11059 and initialize gdb_interface data structures.
11061 * gdb_interface.h: Under Windows, gdb_interface cannot be
11062 initialized statically. Initialize at runtime instead.
11064 * fports.c (write_all): ssize_t -> size_t.
11065 (fport_print): Conditionalize call to ttyname().
11066 (getflags): New function, compiled only under Windows.
11068 * filesys.c: Conditionalize inclusion of <pwd.h>. Conditionalize
11069 primitives chown, link, fcntl.
11070 (scm_basename, scm_dirname): Under Windows, handle \ as well as /
11073 * backtrace.c: Include <io.h> under Windows.
11075 * async.h (ASYNCH, SCM_ASYNC_H): Rename <foo>H to SCM_<foo>_H.

11109 2001-06-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
11111 * filesys.c (scm_close), ports.c (scm_close_port,
11112 scm_port_closed_p), strop.c (scm_string_null_p): Use SCM_BOOL

11147 (scm_symbol_to_string): Fix gc problem.
11149 * strings.h (STRINGSH, SCM_STRINGS_H): Rename <foo>H to
11152 * validate.h (SCM_VALIDATE_SUBSTRING_SPEC_COPY): Eliminate
11153 warning about comparing signed and unsigned values. This fix is
11154 not optimal, since it won't work reliably if sizeof (c_start) >
11155 sizeof (size_t) or sizeof (c_end) > sizeof (size_t). A better
11156 solution is to define this macro as an inline function, thus
11157 allowing to specifiy the types of c_start and c_end.

11171 operations in conditions.
11173 (narrow_stack, scm_make_stack, scm_stack_id,
11174 scm_last_stack_frame): Get rid of redundant SCM_N?IMP checks.
11176 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Clean up
11177 type dispatch. No need to cast result of SCM_DEBUGOBJ_FRAME any
11180 (scm_stack_ref, scm_frame_previous, scm_frame_next): Fix

11199 * Makefile.am (guile_filter_doc_snarfage): build using
11200 c-tokenize.c, not filter-doc-snarfage.c.
11201 rearrange snarfing dependencies a bit.

11210 Thanks to Seth Alves!
11212 * numbers.c (SIZE_MAX, PTRDIFF_MIN, PTRDIFF_MAX): Only define when
11213 they aren't defined already.
11215 2001-06-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
11217 * backtrace.c (display_backtrace_body): Use SCM_VALIDATE_STACK
11218 and SCM_VALIDATE_OPOUTPORT instead of SCM_ASSERT. Fix signedness
11221 * backtrace.c (display_expression, scm_set_print_params_x,
11222 display_application, display_frame, scm_backtrace), numbers.c

11639 value of 2 now corresponds to the former 1, the current 1
11640 corresponds to the former situation that SCM_VOIDP_TEST was
11643 (SCM): Now defined as typedef struct scm_unused_struct * SCM;
11644 If this appears to be not ANSI compliant, we will change it to

11646 Thanks to Han-Wen Nienhuys for the suggestion.
11648 * unif.c (scm_array_set_x): Fix typing problem, and use

11697 Changed use of scm_array->scm_array_t and
11698 scm_array_dim->scm_array_dim_t to enable build with
11699 --disable-deprecated.
11701 2001-05-24 Michael Livshin <mlivshin@bigfoot.com>
11703 The purpose of this set of changes is to regularize Guile's usage
11704 of ANSI C integral types, with the following ideas in mind:
11706 - SCM does not nesessarily have to be long.
11707 - long is not nesessarily enough to store pointers.
11708 - long is not nesessarily the same size as int.
11710 The changes are incomplete and possibly buggy. Please test on
11714 (SCM_NUM2{SIZE,PTRDIFF,SHORT,USHORT,BITS,UBITS,INT,UINT}[_DEF]):
11717 * unif.h: type renaming:
11718 scm_array -> scm_array_t
11719 scm_array_dim -> scm_array_dim_t

12165 * feature.c (features): Renamed to features_var. Now points to a
12166 variable instead of a vcell. Updated all uses.

12195 (scm_init_eval): Use scm_define to initialize "nil" and "t" to
12196 scm_lisp_nil and scm_lisp_t, respectively. Use scm_define instead

12213 instead of a vcell. Updated all uses.

12668 * mallocs.c (scm_malloc_obj): Remove un-matched SCM_ALLOW_INTS.
12670 * gc.c (scm_igc): Unconditionally call

12688 (SCM_DEFER_INTS, SCM_ALLOW_INTS_ONLY, SCM_ALLOW_INTS,
12689 SCM_REDEFER_INTS, SCM_REALLOW_INTS): Don't use
12690 SCM_THREAD_DEFER/SCM_THREAD_ALLOW. Instead, use
12691 SCM_CRITICAL_SECTION_START/END.
12692 (SCM_REALLOW_INTS: Bug fix. Don't call
12693 SCM_THREAD_SWITCHING_CODE.
12694 (SCM_TICK): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS. Instead, use
12695 SCM_THREAD_SWITCHING_CODE directly.
12696 (SCM_ENTER_A_SECTION): Unconditionally use
12697 SCM_CRITICAL_SECTION_START/END. (was:
12698 SCM_DEFER_INTS/SCM_ALLOW_INTS when SCM_POSIX_THREADS defined).
12700 2001-04-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
12702 * __scm.h (SCM_CAREFUL_INTS, SCM_DEBUG_INTERRUPTS): Replaced the
12703 macro SCM_CAREFUL_INTS by the macro SCM_DEBUG_INTERRUPTS and
12704 allowed to explicitly set this macro via the CFLAGS variable
12707 * fluids.c (next_fluid_num), gc.c (scm_igc), coop-defs.h
12708 (SCM_THREAD_CRITICAL_SECTION_START,

12725 * init.c, goops.c, goops.h: Reverted change of 2001-03-29. (The
12726 goops module should be registered in order to work for an
12727 application which uses libguile statically linked.)

12871 2001-04-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
12873 * gc.c (MARK): Re-introduce a cheap sanity test for non debug
12874 mode, as suggested by Michael Livshin.
12876 2001-03-31 Michael Livshin <mlivshin@bigfoot.com>
12878 * backtrace.c (display_backtrace_body): since the `print_state'
12879 variable is not used (instead its data field is used directly as
12880 `pstate'), protect it from the hungry compiler optimizations.
12881 thanks to Bill Schottstaedt for the report.
12883 2001-03-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
12885 * gc.[ch] (scm_tc16_allocated): New type tag for allocated cells.
12886 It is only defined and used if guile is compiled with
12887 SCM_DEBUG_CELL_ACCESSES set to true. It's purpose is, to never
12888 let cells with a free_cell type tag be visible outside of the
12889 garbage collector when in debug mode.
12891 * gc.c (scm_debug_cell_accesses_p): Set to true as default.
12893 (scm_assert_cell_valid): Use a local static variable to avoid
12896 (MARK): Only check for rogue cell pointers in debug mode. Use
12897 scm_cellp for this purpose and place all checks for rogue pointers
12898 into that function. Further, since due to conservative scanning
12899 we may encounter free cells during marking, don't use the standard
12900 cell type accessor macro to determine the cell type.
12902 (scm_cellp): Check if the cell pointer actually points into a
12905 (scm_init_gc): Initalize scm_tc16_allocated.
12907 * gc.h (GCH): Renamed to SCM_GC_H.
12909 (SCM_VALIDATE_CELL): Enclose the expression in brackets. This
12910 might be unnecessary, but I feel better this way :-)
12912 (SCM_GC_CELL_TYPE): New macro.
12914 (SCM_SETAND_CDR, SCM_SETOR_CDR): Deprecated. These are not used
12915 in guile, and it is unlikely that they will be applied to real
12918 (SCM_SET_FREE_CELL_TYPE): Removed. It was not used.
12920 (SCM_GC_SET_ALLOCATED): New macro. Only non-empty if guile is
12921 compiled with SCM_DEBUG_CELL_ACCESSES set to true.
12923 (SCM_NEWCELL, SCM_NEWCELL2): Use of SCM_GC_SET_ALLOCATED will
12924 make sure that in debug mode no free cell will ever be visible
12925 outside of the garbage collector.
12927 2001-03-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
12929 * async.c (scm_asyncs_pending): Don't use != to compare SCM
12932 * async.c (scm_system_async), variable.c (scm_make_variable,
12933 scm_make_undefined_variable): Use scm_cons to create a pair.
12935 * debug.c (scm_reverse_lookup): Perform proper type checking.
12936 Remove suspicious use of SCM_SLOPPY_CONSP.
12938 * eq.c (scm_equal_p), tags.h (SCM_ECONSP): Use SCM_CONSP instead
12939 of SCM_SLOPPY_CONSP. A sane compiler should be able to perform
12940 the corresponding optimization.
12942 * eval.c (iqq): Use proper type check.
12944 (scm_m_expand_body): Remove redundant type checks.
12946 (promise_print): Don't access promise cells as pairs.
12948 * eval.c (EVALCAR, iqq, scm_m_expand_body, scm_eval_args,
12949 scm_deval_args SCM_CEVAL), guardians.c (scm_guard), hashtab.c
12950 (scm_internal_hash_fold), print.c (scm_iprlist): Use !SCM_CELLP
12951 for SCM_NCELLP, !SCM_CONSP for SCM_NCONSP, !SCM_IMP for SCM_NIMP,
12952 !SCM_FALSEP for SCM_NFALSEP, !SCM_NULLP for SCM_NNULLP
12954 * eval.c (scm_m_define, scm_macroexp, SCM_CEVAL), print.c
12955 (scm_iprin1): Use new macro predicate and accessors.
12957 * eval.h (scm_tc16_macro): Removed declaration. It is declared
12960 * eval.h (EVALH), macros.h (MACROSH), ports.h (PORTSH), procs.h
12961 (PROCSH), tags.h (TAGSH), variable.h (VARIABLEH): Renamed to
12962 SCM_EVAL_H, SCM_MACROS_H, SCM_PORTS_H, SCM_PROCS_H, SCM_TAGS_H and
12963 SCM_VARIABLE_H. Even the macros that are used to inhibit
12964 including a header file twice should be in the SCM_ namespace.
12966 * fluids.c (scm_swap_fluids, scm_swap_fluids_reverse),
12967 properties.c (scm_primitive_property_ref,
12968 scm_primitive_property_del_x): Prefer stronger predicates like
12969 SCM_NULLP or SCM_FALSEP over SCM_IMP.
12971 * gc.c (MARK): Use proper macros to access procedure-with-setter
12972 cell elements and closure cell elements.
12974 (gc_sweep_freelist_finish, scm_gc_sweep, init_heap_seg): Don't
12975 access free cells as pairs.
12977 (scm_unprotect_object): scm_hashq_get_handle returns #f if
12978 no hashtab entry is found.
12980 * gc.c (scm_gc_sweep), ports.c (scm_close_port): Use new macro
12981 SCM_CLR_PORT_OPEN_FLAG.
12983 * guardians.c (TCONC_IN), print.c (scm_free_print_state): Don't
12984 use SCM_SET_C[AD]R for uninitialized cells.
12986 * hashtab.c (scm_hash_fn_get_handle): Use SCM_VALIDATE_VECTOR.
12987 If the hashtable has no slots, return #f instead of '(). This
12988 unifies the return value with most assoc-functions.
12990 (scm_hash_fn_ref): Use proper type check.
12992 (scm_hashq_get_handle, scm_hashv_get_handle, scm_hash_get_handle):
12993 Removed references to non-existing functions from documentation.
12995 * keywords.c (scm_keyword_dash_symbol): Use proper macros to
12996 access keyword cell elements.
12998 * macros.h (SCM_MACROP, SCM_MACRO_TYPE, SCM_MACRO_CODE): New
13001 * ports.h (SCM_CLR_PORT_OPEN_FLAG): New macro.
13003 * print.c (scm_iprlist): Added comment. Improved loop
13006 * procs.h (SCM_ENV, SCM_SETENV): Don't access closure cells as
13009 * smob.c (scm_markcdr): Don't access smob cells as pairs.
13011 * tags.h (SCM_SLOPPY_CONSP, SCM_SLOPPY_NCONSP): Deprecated.
13013 * throw.c (ACTIVATEJB, DEACTIVATEJB): Don't access jump buffer
13016 * variable.c (variable_print, variable_equalp, scm_variable_ref,
13017 scm_variable_set_x): Use proper macros to access variable cell
13020 (scm_variable_bound_p): Don't use SCM_NEGATE_BOOL.
13022 * variable.h (SCM_VARVCELL): Don't access variable cells as
13025 * vectors.c (scm_vector), weaks.c (scm_weak_vector): Simplified,
13026 added FIXME comment, removed register specifier.
13028 2001-03-29 Keisuke Nishida <kxn30@po.cwru.edu>
13030 * goops.c, goops.h (scm_init_oop_goops_goopscore_module): Deprecated.
13031 * init.c (scm_init_guile_1): Don't init goopscore module.
13033 2001-03-27 Marius Vollmer <mvo@zagadka.ping.de>
13035 * eval.c (SCM_APPLY): Check that arg1 is bound for scm_tc7_cxr.
13037 2001-03-27 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
13039 * strop.c (scm_string_to_list): Fixed docstring markup.
13040 (scm_string_upcase_x, scm_string_upcase, scm_string_downcase_x),
13041 (scm_string_downcase, scm_string_capitalize_x),
13042 (scm_string_capitalize): Rewrote and corrected docstrings.
13043 (scm_string_ci_to_symbol): Made docstring more explicit.
13045 2001-03-27 Marius Vollmer <mvo@zagadka.ping.de>
13047 * values.h (scm_values_vtable, SCM_VALUESP): Moved here so that
13049 (scm_call_with_values): Removed.
13050 * values.c (values_vtable, scm_values_vtable): Added "scm_" prefix
13051 so that it can be exported.
13052 (scm_call_with_values): Removed.
13054 * tags.h (SCM_IM_CALL_WITH_VALUES): New isym.
13055 * eval.c: Include "libguile/values.h"
13056 (scm_m_at_call_with_values, scm_sym_at_call_with_values):
13058 (unmemocopy, scm_ceval, scm_deval): Handle new isym.
13059 * eval.h (scm_sym_at_call_with_values, scm_m_at_call_with_values):
13060 New delcarations to support above change.
13062 * eval.c (scm_primitive_eval_x, scm_primitive_eval): Fix syntax
13063 errors with last change.
13065 2001-03-25 Marius Vollmer <mvo@zagadka.ping.de>
13067 * eval.c (scm_primitive_eval_x, scm_primitive_eval, scm_i_eval_x,
13068 scm_i_eval): Moved the application of the system transformer from
13069 scm_i_eval to scm_primitive_eval.

13366 * ramap.c (racp): Removed optimization which caused array copying
13367 to fail if the two arrays shared storage. Re-inserted the IVDEP
13368 macros removed in the change of 2000-03-09. (Don't really have a
13369 complete grasp of what they are for, but they seem to be necessary
13370 on Crays. This needs testing!) Thanks to Miroslav Silovic.

13421 the underlying functions getservent, getprotoent or getnetent
13422 return NULL instead of signalling an error.

13435 to INUM: allow full range of int or size_t.

13437 avoid leakage. use malloc, not scm_must_malloc.
13438 (scm_connect, scm_bind, scm_sendto): use int, not size_t as socklen_t
13439 substitute. free the sockaddr structure before throwing an error.
13440 (scm_init_add_buffer): procedure removed, together with its static
13441 buffer scm_addr_buffer, which wouldn't be thread safe. instead,
13442 define a macro MAX_ADDR_SIZE and declare the buffer where needed.
13443 (scm_accept, scm_getpeername, scm_getsockname, scm_recvfrom,
13444 scm_sendto): use a local buffer instead of scm_addr_buffer.
13445 adjust for new SCM_SOCK_FD_TO_PORT. use int for address size,

13448 call to detect whether recvfrom could be bothered to set the address.
13449 (scm_init_socket): don't call scm_init_addr_buffer.

13498 immediate, literal constant should be evaluated.
13499 * eval.c (scm_s_duplicate_formals): New error message string.
13500 (scm_c_improper_memq): New function.
13501 (scm_m_lambda): Check for duplicate arguments.
13502 (scm_ceval, scm_deval): When executing a body: only cons a new
13503 toplevel environment frame when it is different from the
13504 existing one; use EVALCAR instead of SIDEVAL so that we can properly
13505 check for empty combinations; use SCM_EVALIM2 for the same reason
13506 in the non-toplevel loop.
13507 (nontoplevel_cdrxnoap, nontoplevel_cdrxbegin, nontoplevel_begin):
13508 New labels with the meaning of their non-"nontoplevel" partners,
13509 but they are used when it is known that the body is not evaluated at
13511 (scm_apply, scm_dapply): use SCM_EVALIM2 to get proper error
13512 reporting for empty combinations.
13514 2001-03-02 Keisuke Nishida <kxn30@po.cwru.edu>
13516 * Remove dump facilities.

13536 (scm_string_gr_p, scm_string_geq_p, scm_string_ci_less_p)
13537 (scm_string_ci_geq_p), symbols.c (scm_symbol_p)
13538 (scm_symbol_to_string, scm_string_to_symbol): Changed use of @t{}
13539 to @code{} as the texinfo manual recommends, converted the
13540 examples to use a @lisp{}-environment.
13542 * strports.c (scm_eval_string): Cleaned up the docstring.
13544 * struct.c (scm_struct_p, scm_struct_vtable_p): Added texinfo

13549 (scm_real_p, scm_integer_p, scm_inexact_p, scm_make_rectangular)
13550 (scm_make_polar, scm_inexact_to_exact): Added texinfo markup.
13551 (scm_ash): Added texinfo markup and removed obsolete @refill.
13552 (scm_gr_p): Corrected comment.

13561 (scm_magnitude, scm_angle, scm_abs, scm_quotient, scm_remainder)
13562 (scm_modulo, scm_gcd, scm_lcm): Added (future docstring) comments.
13564 2001-02-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
13566 * __scm.h (SCM_ASSERT_TYPE): Add missing macro parameter.
13567 (Obviously nobody compiles with SCM_RECKLESS defined...)
13569 * validate.h (SCM_ASSERT_RANGE): Use the argument number.
13571 2001-02-23 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
13573 * ports.c, ports.h (scm_c_read, scm_c_write): New functions.

13580 scm_make_polar): Rename arguments `z1' and `z2' to `x' and `y',
13581 since use of `z' suggests that the arguments may be complex.
13583 * goops.c (scm_make), numbers.c (scm_sys_expt): Fix docstring
13586 2001-02-23 Neil Jerram <neil@ossau.uklinux.net>

13595 * load.c (load): Use scm_primitive_eval_x instead of scm_i_eval_x.
13597 * goops.c (scm_add_method, DEFVAR): Use scm_eval instead of
13599 (make_class_from_template): Do not bother to set the current
13600 module around the call to DEFVAR, scm_eval takes care of that.
13601 (scm_init_goops): Make scm_module_goops and
13602 scm_goops_lookup_closure permanent objects.
13604 * eval.c (scm_ceval, scm_deval): When evaluating expressions on
13605 top level, create a fresh top-level environment for each
13606 expression instead of mutating the exisint frame. This is
13607 important when that frame is closed over.
13609 * numbers.c (s_scm_logior) [SCM_DIGSTOOBIG]: Also use
13610 SCM_DIGSPERLONG instead of DIGSPERLONG.
13612 2001-02-21 Marius Vollmer <mvo@zagadka.ping.de>
13614 * eval.c (scm_ceval, scm_deval): Check for wrong number of args
13615 before applying arrow procedure in `cond' and before applying
13616 receiver procedure in call-with-current-continuation.
13617 (scm_i_eval): Do not invoke scm_copy_tree in argument in SCM_XEVAL
13618 macro. The argument is expanded more than one time.
13620 * numbers.c (scm_logior) [SCM_DIGSTOOBIG]: Correctly use
13621 SCM_BIGDIG instead of BIGDIG. Thanks to Steven G. Johnson!
13623 2001-02-20 Marius Vollmer <mvo@zagadka.ping.de>
13625 * guile-doc-snarf.in, guile-func-name-check.in: Added copyright
13626 notice and license.

13661 missing explanation.
13662 (scm_current_load_port, scm_set_current_output_port)
13663 (scm_set_current_error_port, scm_port_line, scm_set_port_line_x):

13666 * arbiters.c (scm_make_arbiter, scm_try_arbiter)
13667 (scm_release_arbiter): Added texinfo markup to docstrings.
13668 Changed `Returns' to `Return'.

13740 2001-02-15 Marius Vollmer <mvo@zagadka.ping.de>
13742 * symbols.c (scm_mem2symbol): Put a empty statement after the
13743 next_symbol label. This is mandated by ANSI, appearantly.
13745 2001-02-13 Marius Vollmer <marius.vollmer@uni-dortmund.de>
13747 * gc_os_dep.c: Do not include <linux/version.h>. It makes no
13748 sense to compile for a specific kernel version. Do not include
13749 <asm/signal.h> while defining __KERNEL__. This hack should no
13750 longer be needed and caused problems.
13752 2001-02-13 Marius Vollmer <mvo@zagadka.ping.de>
13754 * eval.c (scm_ceval, scm_deval): use `SIDEVAL' instead of
13755 SCM_CEVAL when evaluating subforms of `begin' forms. SCM_CEVAL

13770 * eval.h (scm_primitive_eval, scm_primitive_eval_x): New
13772 (scm_i_eval, scm_i_eval_x, scm_eval, scm_eval_x): Changed argument
13773 names to better reflect their meaning.
13775 * eval.c (scm_ceval, scm_deval): Recognize when `begin' is being
13776 evaluated at top-level and synronize lookup closure before
13777 executing every subform.
13778 (scm_primitve_eval_x, scm_primitive_eval): New functions.
13779 (scm_eval_x, scm_eval): Reimplement in terms of
13780 scm_primitive_eval_x and scm_primitive_eval, respectively.
13782 2001-02-09 Marius Vollmer <mvo@zagadka.ping.de>
13784 * macros.c (scm_macro_name, scm_macro_transformer): Use
13785 SCM_SMOB_DATA instead of SCM_CDR. Provided by Martin Grabmueller.
13788 2001-02-10 Keisuke Nishida <kxn30@po.cwru.edu>
13790 * dump.c (scm_store_bytes): Store data size before data.
13791 (scm_restore_bytes): Restore data size. Takes a pointer to size.
13792 * dump.h (scm_restore_bytes): Updated.
13794 2001-02-09 Keisuke Nishida <kxn30@po.cwru.edu>
13796 * dump.c: Use double cells for update schedule.
13798 2001-02-08 Keisuke Nishida <kxn30@po.cwru.edu>
13800 * ports.c (scm_unread_char): Take an optional argument.
13802 2001-02-08 Marius Vollmer <marius.vollmer@uni-dortmund.de>
13804 * modules.h (scm_selected_module, scm_current_module): Renamed
13805 scm_selected_module to scm_current_module to synchronize Scheme
13807 (scm_select_module, scm_set_current_module): Likewise. Changed
13810 * ports.c (scm_port_for_each): Make a snapshot of the port table
13811 before iterating over it. The table might change while the user
13812 code is running. With the snapshot, the user can depend on the
13813 fact that each port that existed at the start of the iteration is
13814 encountered exactly once. (ice-9 popen) depends on this.
13816 2001-02-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
13818 * strings.h (SCM_STRING_MAX_LENGTH): New macro.
13820 * strings.c (scm_makstr, scm_take_str, scm_make_string): Added
13821 range checking for the size parameter. Thanks to Martin
13822 Grabmueller for the hint.
13824 (scm_makstr): Reordered string initialization to make interrupt
13825 deferring unnecessary.
13827 * vectors.c (scm_make_vector): Fixed range checking.
13829 2001-02-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
13831 * vectors.h (SCM_VECTOR_MAX_LENGTH): New macro.
13833 * vectors.c (scm_make_vector, scm_c_make_vector): Improved the
13834 checking of the size parameter for type correctness and valid
13835 range. Thanks to Rob Browning for reporting the problem. Instead
13836 of deferring interrupts, scm_remember_upto_here_1 is used.
13838 2001-02-05 Keisuke Nishida <kxn30@po.cwru.edu>
13840 * dump.c (scm_store_cell_object, scm_restore_cell_object): Removed.
13841 (scm_dump_cell_update): Removed.
13842 (scm_dump_update): Renamed from scm_dump_object_update.
13843 (scm_restore_string, scm_restore_bytes, scm_restore_word): Takes
13844 a pointer instead of returning a value.
13845 * keywords.c (keyword_undump): Updated.
13847 2001-02-05 Keisuke Nishida <kxn30@po.cwru.edu>
13849 * dump.c, dump.h: Modified a lot.

13856 New slots: dump, undump.
13857 * smob.c (scm_make_smob_type, scm_set_smob_dump, scm_set_smob_undump):
13860 * keywords.c (keyword_dump): Renamed from keyword_dealloc.
13861 (keyword_undump): Renamed from keyword_alloc.
13862 (scm_init_keywords): Set keyword_dump and keyword_undump.
13864 2001-02-03 Michael Livshin <mlivshin@bigfoot.com>
13866 * gc.c (DOUBLECELL_ALIGNED_P): new macro, a better-named analog of
13867 the deprecated SCM_DOUBLE_CELLP.
13869 * tags.h (SCM_DOUBLE_CELLP): deprecated.
13871 2001-02-02 Keisuke Nishida <kxn30@po.cwru.edu>
13873 * dump.c, dump.h: New files.
13874 * Makefile.am: Added dump.c, dump.h, dump.x, dump.doc.
13875 * init.c: #include "libguile/dump.h".
13876 (scm_init_guile_1): Call scm_init_dump.
13877 * smob.h (scm_smob_descriptor): New slots: dump_mark,
13878 dump_dealloc, dump_store, undump_alloc, undump_restore,
13880 * smob.c (scm_make_smob_type): Init the new slots.
13881 (scm_set_smob_dump, scm_set_smob_undump): New functions.
13882 * smob.h (scm_set_smob_dump, scm_set_smob_undump): Declared.

13943 The following patch was sent by Martin Grabmueller. It makes sure
13944 that in case of parameter errors the correct function name is
13945 shown, and that parameter types are only checked once.
13947 * strop.c (string_copy, string_upcase_x, string_downcase_x,
13948 string_capitalize_x): New functions. Each one performs the core
13949 functionality of the corresponding scm_* function.

14192 (scm_get_one_zombie): remove redundant property test.
14193 (guardian_t): represent the various (currently 3, I hope nothing
14194 more gets added) boolean fields as bit flags.
