3 * eval.c, filesys.c, gc.c, numbers.c, stime.c, threads.c: Don't
4 define `_GNU_SOURCE' explicitly as it's now defined in
5 <config.h> thanks to `AC_USE_SYSTEM_EXTENSIONS'.
7 2008-08-19 Han-Wen Nienhuys <hanwen@lilypond.org>
8 Ludovic Courtès <ludo@gnu.org>
10 * goops.c (scm_init_goops_builtins, go_to_hell): Fix allocation
11 of `hell' by passing "hell_size * sizeof (*hell)" instead of
12 "hell_size" to `scm_malloc ()' and `scm_realloc ()'.
14 2008-08-02 Neil Jerram <neil@ossau.uklinux.net>
16 * numbers.c (scm_rationalize): Update docstring to match the
17 manual (which is more correct). Change argument "err" to "eps",
18 also to match the manual.
20 2008-07-17 Neil Jerram <neil@ossau.uklinux.net>
22 From Thiemo Seufer <ths@networkno.de>:
24 * gc_os_dep.c (CPP_WORDSZ, ALIGN_DOUBLE, DATAEND,
25 DYNAMIC_LOADING): Added #defines.
26 (_fdata, _end): Added declarations.
27 (DATASTART): Use _fdata instead of __data_start.
28 (STACKBOTTOM): Changed from 0x80000000 to 0x7fff8000.
30 2008-07-16 Ludovic Courtès <ludo@gnu.org>
32 * gen-scmconfig.h.in (SCM_I_GSC_HAVE_STRUCT_DIRENT64): New.
33 * gen-scmconfig.c (main): Produce definitions of
34 `SCM_HAVE_STRUCT_DIRENT64' and `SCM_HAVE_READDIR64_R'.
35 * _scm.h (dirent_or_dirent64): Depend on
36 `SCM_HAVE_STRUCT_DIRENT64', for the sake of HP-UX 11.11.
37 (readdir_r_or_readdir64_r): Depend on `SCM_HAVE_READDIR64_R',
40 2008-07-05 Ludovic Courtès <ludo@gnu.org>

43 * strings.h (scm_c_symbol_length): New declaration.
45 2008-07-04 Ludovic Courtès <ludo@gnu.org>
47 * posix.h (scm_i_locale_mutex): Don't declare as `SCM_INTERNAL'
48 since it's needed by `libguile-i18n'. Reported by Patrick
49 Horgan <phorgan1@gmail.com>.
51 * __scm.h (SCM_INTERNAL): Add `extern' so that these symbols are
52 not considered as "common" by GCC 4.3. Reported by Patrick
53 Horgan <phorgan1@gmail.com>.
55 2008-06-28 Ludovic Courtès <ludo@gnu.org>
57 * Makefile.am (INCLUDES): Renamed to...
58 (AM_CPPFLAGS): this, to match current Automake conventions.
61 * tags.h (SCM_UNPACK): Disable type-checking for `__DECC' and
62 `__HP_cc'. Reported by Peter O'Gorman <pogma@thewrittenword.com>.
64 2008-06-02 Ludovic Courtès <ludo@gnu.org>
66 * deprecated.c (maybe_close_port): Rename EXCEPT to EXCEPT_SET
67 to workaround `#define except' on Tru64. Reported by Peter
68 O'Gorman <pogma@thewrittenword.com>.
70 2008-05-31 Ludovic Courtès <ludo@gnu.org>
72 * __scm.h (SCM_INTERNAL): New macro.
73 * *.h: Use it to mark as internal `scm_i_' and `scm_init_'
74 functions that are not used by public macros or inline
77 2008-05-14 Julian Graham <joolean@gmail.com>
79 * threads.c (fat_mutex)[recursive]: New field.
80 (make_fat_mutex): Adjust initialization to reflect changes to
81 mutex lock level semantics.
82 (fat_mutex_lock, fat_mutex_unlock): Add support for unowned
83 mutexes and locking mutexes on behalf of other threads.
84 (scm_lock_mutex, scm_lock_mutex_timed): Update to reflect
85 signature change to fat_mutex_lock.
86 (scm_mutex_owner, scm_mutex_level, scm_mutex_locked_p): New /
88 * threads.h (scm_mutex_owner, scm_mutex_level,
89 scm_mutex_locked_p): Prototypes for new functions.
91 2008-05-12 Neil Jerram <neil@ossau.uklinux.net>
93 * discouraged.c: Expand DEFFROM and DEFTO macros, to avoid
94 compiler warnings about excess semicolons. (Reported by Didier
97 2008-05-08 Neil Jerram <neil@ossau.uklinux.net>
99 * throw.c (scm_ithrow): For IA64 add a return statement, to
102 * threads.h (scm_i_thread): New IA64 fields:
103 register_backing_store_base and pending_rbs_continuation.
105 * threads.c (guilify_self_1): For IA64: cap RBS base address at
106 the current value of scm_ia64_ar_bsp, and store the capped value
108 (SCM_MARK_BACKING_STORE): Use thread->register_backing_store_base
109 instead of scm_ia64_register_backing_store_base().
110 (scm_threads_mark_stacks): Add "&" in "&t->regs", so that the code
111 works both for jmp_buf defined as an array, and jmp_buf defined as
114 * continuations.h (scm_t_contregs): Remove `fresh' and `ctx'
115 fields; these are now inside the IA64 definition of `jmp_buf'.
117 * continuations.c (scm_make_continuation): Simplify, by moving
118 some of the IA64 code inside the definition of "setjmp", and by
119 some obvious commonizations. For IA64 register backing store
120 (RBS) stack base, use thread->register_backing_store_base instead
121 of scm_ia64_register_backing_store_base().
122 (copy_stack): For IA64, store pointer to continuation being
123 invoked in thread state, so we can restore the continuation's RBS
124 stack just before the next setcontext call.
125 (copy_stack_and_call): Don't restore RBS stack explicitly here.
126 It will be restored, if appropriate, inside the longjmp call.
127 (scm_ia64_longjmp): New function.
129 * __scm.h (setjmp, longjmp, jmp_buf): For IA64, implement using
130 getcontext and setcontext.
132 2008-05-07 Ludovic Courtès <ludo@gnu.org>
134 * numbers.c (scm_from_complex_double): Mark as `SCM_UNUSED'.
135 This fixes compilation with `-Werror' on FreeBSD 6.2 (i386).
137 2008-05-05 Neil Jerram <neil@ossau.uklinux.net>
139 * c-tokenize.lex: #define YY_NO_INPUT.
141 2008-04-26 Ludovic Courtès <ludo@gnu.org>
143 * read.c (scm_read_sexp): Remove extraneous semi-colon at
144 end-of-line, which broke compilation with GCC 2.7. Reported by
145 Alain Guibert <alguibert+bts@free.fr>.
147 2008-04-24 Ludovic Courtès <ludo@gnu.org>
149 * Makefile.am (DEFAULT_INCLUDES): New. Fixes compilation on
150 Tru64 where our "random.h" would shadown libc's one.
151 (INCLUDES): Add "-I$(top_buildir)", which is normally in
153 * gen-scmconfig.c: Include <libguile/gen-scmconfig.h>, not
154 "gen-scmconfig.h" since that file is under `$(builddir)'.
156 2008-04-16 Ludovic Courtès <ludo@gnu.org>
158 * ports.c (scm_getc, scm_putc, scm_puts): Moved...
159 * inline.h: ... here. Noticeably improves `read' performance.
161 2008-04-15 Ludovic Courtès <ludo@gnu.org>
162 Julian Graham <joolean@gmail.com>
164 * read.c (scm_keyword_postfix): New.
165 (scm_read_opts): Update docstring for `keywords'.
166 (scm_read_mixed_case_symbol): Add support for postfix keywords.
168 2008-04-13 Ludovic Courtès <ludo@gnu.org>
170 * inline.h (SCM_C_USE_EXTERN_INLINE): New macro. Use it to make
171 sure "extern" declarations are produced when "extern inline" is
172 used. Simplify macrology around inline definitions.
174 2008-04-10 Ludovic Courtès <ludo@gnu.org>
176 * inline.h (SCM_C_EXTERN_INLINE): Special-case Apple's GCC
177 4.0-based compiler, which doesn't support GNU inline semantics
178 at all in C99 mode but doesn't define `__GNUC_STDC_INLINE__'.
179 See http://thread.gmane.org/gmane.network.gnutls.general/1135 .
181 2008-04-10 Andy Wingo <wingo@pobox.com>
183 * struct.c (scm_struct_ref, scm_struct_set_x): "Light" structs
184 have no hidden words (members of the SCM_STRUCT_DATA(x) array
185 accessed with negative indices). In that case, determine the
186 number of fields from the length of the struct layout
187 descriptor. (Most GOOPS instances are light structs.)
189 * goops.c (wrap_init): Initialize 'u' slots to 0, not some random
192 * goops.c (get_slot_value, set_slot_value): In the struct
193 allocation case, don't poke the slots array directly -- we should
194 go through struct-ref/struct-set! code so that we get the
195 permissions and allocation ('u' versus 'p') correct.
197 2008-04-03 Ludovic Courtès <ludo@gnu.org>
199 * inline.h (SCM_C_EXTERN_INLINE): New macro, addresses the
200 "extern inline" semantic change in C99 mode with GCC 4.3 and
201 later and the warning in C99 mode with GCC 4.2. Use it in the
202 inline function definitions.
204 2008-03-24 Neil Jerram <neil@ossau.uklinux.net>
206 Applying patch from Julian Graham, containing minor fixes to his
209 * threads.c (to_timespec): Change 1000000 multiplier to
211 (unchecked_unlock_sym, allow_external_unlock_sym,
212 recursive_sym): Use SCM_SYMBOL.
213 (scm_make_mutex_with_flags): When raising unsupported option
214 error, report what the unsupported option was.
215 (fat_mutex_unlock): When raising errors, unlock m->lock first.
216 (fat_cond_timedwait): Removed.
217 (scm_timed_wait_condition_variable): Call fat_mutex_unlock
218 directly instead of via fat_cond_timedwait.
220 2008-03-10 Ludovic Courtès <ludo@gnu.org>
222 * eval.c, filesys.c: Enclose `alloca' blob in `#ifndef alloca',
223 as per Gnulib's `alloca'. This should fix compilation on
226 2008-03-09 Neil Jerram <neil@ossau.uklinux.net>
228 * numbers.c: Only define scm_from_complex_double if it will
231 2008-03-08 Julian Graham <joolean@gmail.com>

244 (fat_mutex)[unchecked_unlock, allow_external_unlock]: New fields.
245 (fat_mutex_lock): Reimplement to support timeouts and abandonment.
246 (fat_mutex_trylock, scm_try_mutex): Remove fat_mutex_trylock and
247 reimplement scm_try_mutex as a lock attempt with a timeout of zero.
248 (fat_mutex_unlock): Allow unlocking from other threads and unchecked
249 unlocking; implement in terms of condition variable wait.
250 (scm_timed_wait_condition_variable): Reimplement in terms of
252 * threads.h (scm_i_thread)[mutexes]: New field.
253 (scm_join_thread_timed, scm_thread_p, scm_lock_mutex_timed,
254 scm_unlock_mutex_timed, scm_mutex_p, scm_condition_variable_p):
255 Prototypes for new functions.
257 2008-03-06 Ludovic Courtès <ludo@gnu.org>
259 * eval.c (scm_eval): If MODULE_OR_STATE is not a dynamic state,
260 make sure it's a module. Reported by David I. Lehn.
262 2008-03-02 Ludovic Courtès <ludo@gnu.org>
264 * pairs.h (scm_is_pair): Moved declaration to `inline.h'.
265 * inline.h: Make sure `extern' declarations are not produced
266 when `inline' is supported but GCC is not used. This
267 fixes "mixed linkage" errors with compilers such as
270 2008-02-27 Neil Jerram <neil@ossau.uklinux.net>
272 * _scm.h (errno): Remove declarations that have been there
273 forever, and are known to conflict on some platforms with that
274 provided by <errno.h>, which we include unconditionally. If
275 <errno.h> doesn't provide a errno declaration, what is the point
278 2008-02-23 Ludovic Courtès <ludo@gnu.org>
280 * numbers.c (scm_make_rectangular): Rename argument to
281 `real_part' and `imaginary_part' to work around Solaris 2.10
282 headers which define `imaginary' as a macro. Patch by Tim
283 Mooney <mooney@dogbert.cc.ndsu.NoDak.edu>.
285 2008-02-22 Ludovic Courtès <ludo@gnu.org>
287 * read.c (strncasecmp): Add declaration when

313 * guile-snarf.in (tempdir): Honor `$TMPDIR'.
315 2008-02-11 Neil Jerram <neil@ossau.uklinux.net>
317 * numbers.c (SCM_COMPLEX_VALUE): Use GUILE_I instead of _Complex_I
318 directly, and only if GUILE_I was defined by the configure step.
319 (scm_log, scm_log10, scm_exp, scm_sqrt): Use SCM_COMPLEX_VALUE
320 code only if SCM_COMPLEX_VALUE is defined.
322 2008-02-07 Ludovic Courtès <ludo@gnu.org>
325 Thanks to David Diffenbaugh <davediff@nbcs.rutgers.edu>.
327 * read.c (scm_read_quote): Don't use `__FUNCTION__' since it is
328 not supported by Sun CC on Solaris 9.
329 (scm_read_keyword): Likewise.
330 * strings.c (scm_take_locale_stringn): Remove
331 `SCM_C_INLINE_KEYWORD' to allow compilation with Sun CC.

352 scm_i_normbig): Remove `SCM_C_INLINE_KEYWORD' since these are
353 declared as `extern' in `numbers.h'. This precluded compilation
354 on Solaris 9 with Sun CC (reported by David Halik
355 <dhalik@nbcs.rutgers.edu>).
357 2008-02-05 Neil Jerram <neil@ossau.uklinux.net>

382 2007-12-29 Neil Jerram <neil@ossau.uklinux.net>
384 * gc.c (mark_gc_async): Change "func_data" to "fn_data", to avoid

480 * i18n.c (scm_make_locale)[!USE_GNU_LOCALE_API]: Don't call
481 `leave_locale_section ()' on failure of

501 * posix.c (scm_putenv): Confine the putenv("NAME=") bit to mingw, use
502 putenv("NAME") as the fallback everywhere else. In particular this is
503 needed for solaris 9. Reported by Frank Storbeck.
505 2007-09-03 Ludovic Courtès <ludo@gnu.org>
507 * read.c (flush_ws): Handle SCSH block comments.

521 (scm_accept, scm_getsockname, scm_getpeername, scm_recvfrom):
522 Use `scm_t_max_sockaddr' instead of "char max_addr[MAX_ADDR_SIZE]".
524 2007-09-03 Kevin Ryde <user42@zip.com.au>
526 * numbers.c (scm_log): Test HAVE_CLOG as well as HAVE_COMPLEX_DOUBLE
527 before using clog(). It's possible for gcc to provide the "complex
528 double" type, but for the system not to have the complex funcs.
529 (scm_exp): Ditto HAVE_CEXP for cexp().
530 (clog, cexp, carg): Remove fallback definitions. These only
531 duplicated the code within scm_log and scm_exp, and the latter have to
532 exist for the case when there's no "complex double". So better just
533 fix up the conditionals selecting between the complex funcs and plain
534 doubles than worry about fallbacks.
536 2007-09-02 Ludovic Courtès <ludo@gnu.org>
538 * socket.c (scm_make_socket_address): Free C_ADDRESS after use.
539 This fixes a memory leak.
541 2007-08-26 Han-Wen Nienhuys <hanwen@lilypond.org>
543 * fports.c gc-card.c gc.c gc.h ioext.c ports.c ports.h weaks.h
544 gc.c: replace port table with weak hash table. This simplifies
545 memory management, and fixes freed cells appearing in
546 port-for-each output.
548 * init.c (cleanup_for_exit): abort cleanup if init_mutex is still
551 2007-08-23 Ludovic Courtès <ludo@gnu.org>
553 * read.c (scm_read_quote): Record position and copy source
554 expression when asked to. Reported by Kevin.
556 * stime.c: Define `_REENTRANT' only if not already defined.
558 2007-08-21 Kevin Ryde <user42@zip.com.au>
560 * gc-card.c (scm_i_card_statistics): Record scm_tc7_number types as
561 tc16 values so big, real, complex and fraction can be distinguished.
563 (scm_i_tag_name): Return "number" for scm_tc7_number, not NULL. NULL
564 was making numbers come out as "type 23" in gc-live-object-stats.
565 Fix tests of the tc16 number types, they were checked under
566 scm_tc7_number, but the values went down the tag>=255 smob case.
567 Put smob case under scm_tc7_smob instead of using tag>=255, per
568 recommendation in comments with scm_tc7_smob to use symbolic values.
569 Use SCM_TC2SMOBNUM to extract scm_smobs index, instead of explicit
570 code. Lose some unnecessary "break" statements.
572 (scm_i_card_statistics): Use scm_hashq_create_handle_x and modify the
573 element returned, rather than two lookups scm_hashq_ref and
576 2007-08-17 Kevin Ryde <user42@zip.com.au>
578 * stime.c: Add #define _REENTRANT, to get gmtime_r() prototype on
579 solaris 2.6. Reported by anirkko.
581 2007-07-29 Ludovic Courtès <ludo@gnu.org>
583 * Makefile.am (INCLUDES): Added Gnulib includes.
584 (gnulib_library): New.
585 (libguile_i18n_v_@LIBGUILE_I18N_MAJOR@_la_LIBADD): Added
587 (libguile_la_LIBADD): Likewise.
589 * posix.c: Don't define `_GNU_SOURCE' since `gl_EARLY' arranges
590 to define it when available.
591 * srfi-14.c: Likewise.
592 * i18n.c: Likewise. Include Gnulib's <alloca.h>
593 * eval.c: Include Gnulib's <alloca.h>.
594 * filesys.c: Likewise.
595 * read.c: Don't include <strings.h> and don't provide an
596 `strncasecmp ()' replacement; use Gnulib's <string.h> and
597 `strncasecmp ()' instead.
599 2007-07-25 Ludovic Courtès <ludo@gnu.org>
601 * eval.c (macroexp): When `scm_ilength (res) <= 0', return
602 immediately. This used to produce a circular memoized
603 expression, e.g., for `(set (quote x) #t)'.
605 2007-07-22 Ludovic Courtès <ludo@gnu.org>
607 Overhauled the reader, making it faster.
609 * gdbint.c (tok_buf, tok_buf_mark_p): Removed.
610 (gdb_read): Don't use a token buffer. Use `scm_read ()' instead
613 * read.c: Overhauled. No longer use a token buffer. Use a
614 on-stack C buffer in the common case and use Scheme strings when
615 larger buffers are needed.
616 * read.h (scm_grow_tok_buf, scm_flush_ws, scm_casei_streq,
617 scm_lreadr, scm_lreadrecparen): Removed.
618 (scm_i_input_error): Marked as `SCM_NORETURN'.
620 2007-07-15 Ludovic Courtès <ludo@gnu.org>
622 * script.c (scm_compile_shell_switches): Updated copyright year.
624 2007-07-11 Ludovic Courtès <ludo@gnu.org>
626 * goops.c (scm_sys_method_more_specific_p): Added docstring.
627 Make sure LEN is greater than or equal to the minimum length of
628 specializers of M1 and M2. This fixes a segfault later on in
629 `more_specificp ()' if TARGS is too small. Reported by Marco
630 Maggi <marco.maggi-ipsu@poste.it>.
632 2007-06-26 Ludovic Courtès <ludo@gnu.org>
634 * fluids.c (next_fluid_num): When growing ALLOCATED_FLUIDS, make
635 sure to free the previous array after the new one has been
636 installed. This leak is made visible by running
637 "(define l (map (lambda (i) (make-fluid)) (iota 255)))"
638 from the REPL within Valgrind.
640 2007-06-12 Ludovic Courtès <ludo@chbouib.org>
642 * socket.c (scm_inet_ntop): In the `AF_INET' case, declare `addr4'
643 as an `scm_t_uint32' rather than re-using `addr6'. This fixes a
644 bus error on SPARC (and possibly others) due to unaligned access.
646 2007-06-07 Ludovic Courtès <ludovic.courtes@laas.fr>
648 * posix.c (scm_ttyname): Check whether RESULT is NULL before
649 making a string from it (reported by Dan McMahill). Don't call
650 `scm_from_locale_string ()' before the mutex is released.
652 2007-05-26 Ludovic Courtès <ludo@chbouib.org>
654 * eval.c (scm_m_define): Updated comment. Changed order for value
655 evaluation and `scm_sym2var ()' call, which is perfectly valid per
656 R5RS. This reverts the change dated 2004-04-22 by Dirk Herrmann.
658 2007-05-05 Ludovic Courtès <ludo@chbouib.org>
660 Implemented lazy duplicate binding handling.
662 * modules.c (scm_export): Renamed to...
663 (scm_module_export): This. Now public.
664 (module_variable): Removed.
665 (default_duplicate_binding_procedures_var): New variable.
666 (default_duplicate_binding_handlers, resolve_duplicate_binding,
667 module_imported_variable, scm_module_local_variable,
668 scm_module_variable): New functions.
669 (scm_module_import_interface): Rewritten.
670 (scm_module_reverse_lookup): Exported as a Scheme function.
671 * modules.h (scm_module_index_duplicate_handlers,
672 scm_module_index_import_obarray): New macros.
673 (scm_module_variable, scm_module_local_variable,
674 scm_module_export): New declarations.
676 2007-04-17 Ludovic Courtès <ludovic.courtes@laas.fr>
678 * numbers.c: Commented out trailing `HAVE_COMPLEX_DOUBLE' after
679 `#endif'. Use `#ifndef HAVE_XXX' rather than `#if !HAVE_XXX'.
681 2007-04-09 Han-Wen Nienhuys <hanwen@lilypond.org>
683 * numbers.c (carg): provide carg, cexp, clog in case they are
686 2007-03-12 Ludovic Courtès <ludovic.courtes@laas.fr>
688 * i18n.c (scm_nl_langinfo): `#ifdef'd uses of `GROUPING',
689 `FRAC_DIGITS', etc., which are GNU extensions. Reported by
692 2007-03-08 Kevin Ryde <user42@zip.com.au>
694 * struct.c, struct.h (scm_make_vtable): New function, providing
696 * stacks.c (scm_init_stacks): Use it.
698 2007-03-06 Kevin Ryde <user42@zip.com.au>
700 * struct.c (scm_make_struct): Check for R,W,O at end of layout when
701 allocating a tail array. If there's no such then those tail fields
702 are uninitialized and garbage SCMs there can cause a segv if printed
703 (after fetching with struct-ref).
705 2007-02-22 Kevin Ryde <user42@zip.com.au>
707 * scmsigs.c (scm_sleep): In docstring, cross refence usleep.
708 (scm_usleep): Update docstring per manual, cross reference sleep.
710 * struct.c (scm_make_struct): Move SCM_CRITICAL_SECTION_END up so that
711 scm_struct_init is not within that section. scm_struct_init can
712 thrown an error, which within a critical section results in an
715 2007-02-19 Neil Jerram <neil@ossau.uklinux.net>
717 * Makefile.am (noinst_HEADERS): Add private-options.h, so that it
718 is included in the distribution.
719 (noinst_HEADERS): And the same for eval.i.c.
721 2007-01-31 Ludovic Courtès <ludovic.courtes@laas.fr>
723 * i18n.c: Include "libguile/threads.h" and "libguile/posix.h"
724 unconditionally. Include <langinfo.h> and <nl_types.h> when
726 (SCM_I18N_STRINGIFY, SCM_LOCALE_CATEGORY_MASK,
727 SCM_LIST_OR_INTEGER_P): New macros.
728 (LC_*_MASK): When `USE_GNU_LOCALE_API' is undefined, define them
729 as powers of two instead of `(1 << LC_*)'.
730 (scm_i_locale_free): New function/macro.
731 (scm_global_locale): New global variable.
732 (smob_locale_free): Use `scm_i_locale_free ()'.
733 (smob_locale_mark): Check whether the SMOB is `%global-locale'.
734 (get_current_locale_settings): Return `EINVAL' instead of `errno'
735 when `setlocale' fails.
736 (restore_locale_settings): Likewise.
737 (install_locale_categories): Likewise.
738 (install_locale): Likewise. Stop the locale stack traversal when
739 all categories have been handled.
740 (get_current_locale, category_to_category_mask,
741 category_list_to_category_mask): New function.
742 (scm_make_locale): Use them. Accept both lists of `LC_*' values
743 and single `LC_*' values as the first argument. Handle the case
744 where BASE_LOCALE is `%global-locale'. When `USE_GNU_LOCALE_API',
745 duplicate C_BASE_LOCALE before using it.
746 (scm_nl_langinfo, define_langinfo_items): New functions.
747 (scm_init_i18n): When `HAVE_NL_LANGINFO', add feature
748 `nl-langinfo' and invoke `define_langinfo_items ()'.
749 * i18n.h (scm_global_locale, scm_nl_langinfo): New declarations.
750 * posix.c: Include <xlocale.h> when available.
751 (scm_i_locale_mutex): Always define it. Statically initialized.
752 (scm_set_locale): Invoke `scm_i_to_lc_category ()' before
753 acquiring the locale mutex.
754 (scm_init_posix): No longer initialize SCM_I_LOCALE_MUTEX here.
756 2007-01-27 Kevin Ryde <user42@zip.com.au>
758 * ports.c (scm_port_line, scm_set_port_line_x), read.c
759 (scm_i_input_error, scm_lreadr, scm_lreadrecparen): Corrections to
760 port line number type, should be "long" not "int", as per line_number
761 field of scm_t_port. (Makes a difference only on 64-bit systems, and
762 only then for a linenum above 2Gig.)
764 2007-01-25 Han-Wen Nienhuys <hanwen@lilypond.org>
766 * vector.c: remove comment as per kryde's request.
768 2007-01-25 Kevin Ryde <user42@zip.com.au>
770 * sort.c (scm_stable_sort): Return empty list for input empty list, as
771 done in guile 1.6 and as always done by plain `sort'. Was falling
772 through to SCM_WRONG_TYPE_ARG. Reported by Ales Hvezda.
774 2007-01-22 Han-Wen Nienhuys <hanwen@lilypond.org>
776 * vectors.c (s_scm_vector_move_right_x): complain about naming.
778 * srcprop.c: regularize comments.
780 * eval.c: remove superfluous ifndef DEVAL.
782 * private-options.h: idem.
784 * eval.i.c: copyright nitpicking.
786 * eval.c: distangle. move duplicate code to eval.i.c and include
789 * eval.i.c: new file.
791 * backtrace.c, debug.c, debug.h, deprecation.c, eq.c, eval.c
792 eval.h, gsubr.c, init.c, macros.c, print.c, print.h, read.c,
793 read.h, stacks.c, symbols.c, throw.c: use private-options.h
795 * private-options.h: new file: contain hardcoded option
798 * private-gc.h: add FSF header.
800 2007-01-19 Han-Wen Nienhuys <hanwen@lilypond.org>
802 * debug.h (SCM_RESET_DEBUG_MODE): switch to debugging if
803 memoize-symbol is set.
805 * eval.h (SCM_MEMOIZE_HDLR): add macros for memoize symbol trap.
807 * eval.c (CEVAL): add memoize_symbol trap.
809 * options.c (scm_options_try): new function. This allows error
810 reporting before changing options in a critical section.
812 * srcprop.c: use double cell for storing source-properties. Put
813 filename in the plist, and share between srcprops if possible.
814 Remove specialized storage.
816 * srcprop.h: remove macros without SCM_ prefix from
817 interface. Remove specialized storage/type definitions.
823 * eval.c: terminate option lists with 0.
825 * options.c: remove n (for length) from scm_option_X
826 functions. Detect option list length by looking for NULL name.
828 2007-01-19 Ludovic Courtès <ludovic.courtes@laas.fr>
830 * struct.c (scm_i_struct_equalp): Skip comparison if both FIELD1
831 is equal to S1 and FIELD2 is equal to S2. This avoids infinite
832 recursion when comparing `s' fields, as the REQUIRED_VTABLE_FIELDS
833 added by `make-vtable-vtable'. Reported by Marco Maggi.
835 2007-01-18 Han-Wen Nienhuys <hanwen@lilypond.org>
837 * throw.c (scm_ithrow): more refined error message: print symbols
840 2007-01-16 Kevin Ryde <user42@zip.com.au>
842 * feature.c, feature.h (scm_set_program_arguments_scm): New function,
843 implementing `set-program-arguments'.
845 * filesys.c (scm_init_filesys): Use scm_from_int rather than
846 scm_from_long for O_RDONLY, O_WRONLY, O_RDWR, O_CREAT, O_EXCL,
847 O_NOCTTY, O_TRUNC, O_APPEND, O_NONBLOCK, O_NDELAY, O_SYNC and
848 O_LARGEFILE. These are all int not long, per arg to open().
849 (scm_init_filesys): Use scm_from_int rather than scm_from_long for
850 F_DUPFD, F_GETFD, F_SETFD, F_GETFL, F_SETFL, F_GETOWN, F_SETOWN, these
851 are all ints (per command arg to fcntl). Likewise FD_CLOEXEC which is
854 * posix.c (scm_putenv): Correction to "len" variable, was defined only
855 for __MINGW32__ but used under any !HAVE_UNSETENV (such as solaris).
856 Move it to where it's used. Reported by Hugh Sasse.
858 * regex-posix.c (scm_regexp_exec): Remove SCM_CRITICAL_SECTION_START
859 and SCM_CRITICAL_SECTION_END, believe not needed. Their placement
860 meant #\nul in the input (detected by scm_to_locale_string) and a bad
861 flags arg (detected by scm_to_int) would throw from a critical
862 section, causing an abort().
864 * regex-posix.c (scm_init_regex_posix): Use scm_from_int for
865 REG_BASIC, REG_EXTENDED, REG_ICASE, REG_NEWLINE, REG_NOTBOL,
866 REG_NOTEOL; they're all ints not longs (per args to regcomp and
869 2007-01-10 Han-Wen Nienhuys <hanwen@lilypond.org>
871 * throw.c (scm_ithrow): print out key symbol and string arguments
872 when error happens inside a critical section, and document why.
874 2007-01-06 Han-Wen Nienhuys <hanwen@lilypond.org>
876 * read.c (s_scm_read_hash_extend): document #f argument to
879 2007-01-04 Kevin Ryde <user42@zip.com.au>
881 * deprecated.h (scm_create_hook), version.h.in (scm_major_version,
882 scm_minor_version, scm_micro_version, scm_effective_version,
883 scm_version, scm_init_version): Use SCM_API instead of just extern,
884 for the benefit of mingw. Reported by Cesar Strauss.
886 2007-01-03 Han-Wen Nienhuys <hanwen@lilypond.org>
888 * gc.c (s_scm_gc_stats): return an entry for total-cells-allocated
890 (gc_update_stats): update scm_gc_cells_allocated_acc too.
892 2006-12-27 Kevin Ryde <user42@zip.com.au>
894 * threads.c (get_thread_stack_base): In mingw with pthreads we can use
895 the basic scm_get_stack_base. As advised by Nils Durner.
897 * threads.c (get_thread_stack_base): Add a version using
898 pthread_get_stackaddr_np (when available), for the benefit of MacOS.
899 As advised by Heikki Lindholm.
901 * scmsigs.c (signal_delivery_thread): Restrict scm_i_pthread_sigmask
902 to HAVE_PTHREAD_SIGMASK, it doesn't exist on mingw. Reported by Nils
905 2006-12-24 Kevin Ryde <user42@zip.com.au>
907 * posix.c (scm_kill): When only raise() is available, throw an ENOSYS
908 error if pid is not our own process, instead of silently doing nothing.
910 * print.c (scm_write, scm_display, scm_write_char): Disable port close
911 on EPIPE. This was previously disabled but introduction of HAVE_PIPE
912 check in configure.in unintentionally enabled it. Believe that
913 testing errno after scm_prin1 or scm_putc is bogus, a long ago error
914 can leave errno in that state. popen.test "no duplicates" output test
917 2006-12-23 Han-Wen Nienhuys <hanwen@lilypond.org>
919 * numbers.c (scm_i_fraction_reduce): move logic into
920 scm_i_make_ratio(), so fractions are only read.
921 scm_i_fraction_reduce() modifies a fraction when reading it. A
922 race condition might lead to fractions being corrupted by reading
925 Also, the REDUCED bit alters the SCM_CELL_TYPE(), making
926 comparisons between reduced and unreduced fractions go wrong.
928 * numbers.h: remove SCM_FRACTION_SET_NUMERATOR,
929 SCM_FRACTION_SET_DENOMINATOR, SCM_FRACTION_REDUCED_BIT,
930 SCM_FRACTION_REDUCED_SET, SCM_FRACTION_REDUCED_CLEAR,
931 SCM_FRACTION_REDUCED.
933 2006-12-16 Kevin Ryde <user42@zip.com.au>
935 * scmsigs.c (scm_raise): Use raise() rather than kill(), as this is
936 more direct for a procedure called raise.
937 (kill): Remove mingw fake fallback.
939 2006-12-15 Kevin Ryde <user42@zip.com.au>
941 * scmsigs.c: Conditionalize process.h, add io.h believe needed for
944 2006-12-14 Kevin Ryde <user42@zip.com.au>
946 * threads.c (thread_print): Cope with the case where pthread_t is a
947 struct, as found on mingw. Can't just cast to size_t for printing.
948 Reported by Nils Durner.
950 * scmsigs.c: Add <fcntl.h> and <process.h> needed by mingw. Copy the
951 fallback pipe() using _pipe() from posix.c. Reported by Nils Durner.
953 2006-12-13 Kevin Ryde <user42@zip.com.au>
955 * eval.c (scm_m_define): Set 'name procedure property on any
956 scm_procedure_p, not just SCM_CLOSUREP. In particular this picks up
957 procedures with setters as used in srfi-17.
959 * posix.c (scm_crypt): Check for NULL return from crypt(), which the
960 linux man page says is a possibility.
962 2006-12-12 Ludovic Courtès <ludovic.courtes@laas.fr>
964 * libguile/unif.c (read_decimal_integer): Let RESP be SIGN * RES
965 instead of RES (reported by Szavai Gyula). This allows the use of
966 negative lower bounds.
967 (scm_i_read_array): Make sure LEN is non-negative (reported by
970 (scm_array_in_bounds_p): Iterate over S instead of always
971 comparing indices with the bounds of S[0]. This fixes
972 `array-in-bounds?' for arrays with a rank greater than one and
973 with different lower bounds for each dimension.
975 2006-12-05 Kevin Ryde <user42@zip.com.au>
977 * numbers.c (scm_product): For flonum*inum and complex*inum, return
978 exact 0 if inum==0. Already done for inum*flonum and inum*complex,
979 and as per R5RS section "Exactness".
981 2006-12-03 Kevin Ryde <user42@zip.com.au>
983 * Makefile.am (.c.doc): Remove the "test -n" apparently attempting to
984 allow $AWK from the environment to override. It had syntax gremlins,
985 and the presence of a $(AWK) variable set by AC_PROG_AWK in the
986 Makefile stopped it having any effect. Use just $(AWK), which can be
987 overridden with "make AWK=xxx" in the usual way if desired.
989 2006-11-29 Ludovic Courtès <ludovic.courtes@laas.fr>
991 * libguile/vectors.c (scm_vector_to_list): Fixed list
992 construction: elements were not copied when INC is zero (see
993 "shared array" example in `vectors.test'). Reported by
996 2006-11-18 Ludovic Courtès <ludovic.courtes@laas.fr>
998 * Makefile.am (lib_LTLIBRARIES): Added `libguile-i18n-v-XX.la'.
999 (libguile_la_SOURCES): Added `gettext.c', removed `i18n.c'.
1000 (libguile_i18n_v_XX_la_SOURCES, libguile_i18n_v_XX_la_CFLAGS,
1001 libguile_i18n_v_XX_la_LIBADD, libguile_i18n_v_XX_la_LDFLAGS): New.
1002 (DOT_X_FILES): Added `gettext.x'.
1003 (DOT_DOC_FILES): Likewise.
1004 (EXTRA_libguile_la_SOURCES): Added `locale-categories.h'.
1005 (modinclude_HEADERS): Added `gettext.h'.
1006 (EXTRA_DIST): Added `libgettext.h'.
1008 * gettext.h: Renamed to...
1009 * libgettext.h: New file.
1011 * i18n.c: Renamed to...
1012 * gettext.c: New file.
1014 * i18n.h: Renamed to...
1015 * gettext.h: New file.
1017 * i18n.c, i18n.h, locale-categories.h: New files.
1019 * init.c: Include "libguile/gettext.h" instead of
1021 (scm_i_init_guile): Invoke `scm_init_gettext ()' instead of
1024 * posix.c: Include "libguile/gettext.h" instead of
1025 "libguile/i18n.h" Test `HAVE_NEWLOCALE' and `HAVE_STRCOLL_L'.
1026 (USE_GNU_LOCALE_API): New macro.
1027 (scm_i_locale_mutex): New variable.
1028 (scm_setlocale): Lock and unlock it around `setlocale ()' calls.
1030 * posix.h: Include "libguile/threads.h".

1035 * script.c (scm_shell_usage): Note need for subscription to bug-guile@gnu.org.
1037 2006-11-08 Ludovic Courtès <ludovic.courtes@laas.fr>
1039 * libguile/gc-freelist.c (scm_i_adjust_min_yield): Take two
1040 "sweep_stats" arguments; use them instead of accessing the global
1041 variables `scm_gc_cells_collected' and `scm_gc_cells_collected_1'.
1043 * libguile/gc-segment.c (scm_i_sweep_some_cards): Reset SWEEP
1044 before each iteration of the loop.
1045 (scm_i_sweep_some_segments): Reset SWEEP at each iteration.
1046 (scm_i_get_new_heap_segment): Take an additional argument
1047 SWEEP_STATS. Compute MIN_CELLS as a function of it.
1049 * libguile/gc.c (scm_gc_cells_collected,
1050 scm_gc_cells_collected_1): Removed.
1051 (scm_i_gc_sweep_stats, scm_i_gc_sweep_stats_1): New.

1054 scm_gc_cell_yield_percentage, protected_obj_count): Made `static'.
1055 (scm_gc_stats): Use `scm_i_gc_sweep_stats' instead of
1056 `scm_gc_cells_(collected|swept)'.
1057 (gc_update_stats): New.
1058 (gc_end_stats): Use `scm_i_gc_sweep_stats' and
1059 `scm_i_gc_sweep_stats_1' instead of the former globals.
1060 (scm_gc_for_newcell): Invoke `gc_update_stats ()' after each
1061 `scm_i_sweep_some_segments' call. This fixes a bug where the GC
1062 would keep allocating new segments instead of re-using collected
1063 cells (because `scm_gc_cells_collected' would remain zero).
1065 * libguile/gc.h (scm_gc_cells_swept, scm_gc_cells_collected,
1066 scm_gc_cell_yield_percentage): Removed.
1068 * libguile/private-gc.h (scm_gc_cells_collected_1): Removed.

1102 * coop-pthreads.c (SCM_MARK_BACKING_STORE): Use scm_ia64_ar_bsp()
1103 and scm_ia64_register_backing_store_base() instead of
1104 Linux-specific implementations.
1106 * continuations.h (__libc_ia64_register_backing_store_base):
1107 Declaration removed.
1108 (scm_t_contregs): New "fresh" field.
1110 * continuations.c (ia64_getcontext): Removed.
1111 (scm_make_continuation): Use continuation fresh field instead of
1112 interpreting getcontext return values (which isn't portable). Use
1113 scm_ia64_ar_bsp() and scm_ia64_register_backing_store_base()
1114 instead of Linux-specific implementations.
1115 (copy_stack_and_call): Use scm_ia64_register_backing_store_base()
1116 instead of Linux-specific implementation.
1118 * _scm.h (__ia64__): Also detect __ia64.
1120 2006-10-03 Kevin Ryde <user42@zip.com.au>
1122 * eval.c (SCM_APPLY): For scm_tc7_subr_2o, throw wrong-num-args on 0
1123 arguments or 3 or more arguments. Previously 0 called proc with
1124 SCM_UNDEFINED, and 3 or more silently used just the first 2.
1126 2006-09-28 Kevin Ryde <user42@zip.com.au>
1128 * fports.c, ports.c (ftruncate): Use "HAVE_CHSIZE && ! HAVE_FTRUNCATE"
1129 for chsize fallback, instead of hard-coding mingw. Mingw in fact
1130 supplies ftruncate itself these days.
1132 * ports.c (fcntl.h): Can include this unconditionally, no need for
1135 * ports.c (truncate): Conditionalize on "HAVE_FTRUNCATE && !
1136 HAVE_TRUNCATE" so as not to hard-code mingw. Use "const char *" and
1137 "off_t" for parameters, per usual definition of this function, rather
1138 than "char *" and "int". Use ftruncate instead of chsize. Check for
1139 error on final close.
1141 2006-09-27 Kevin Ryde <user42@zip.com.au>
1143 * numbers.c (scm_log10): Check HAVE_CLOG10, clog10() is not available
1146 * posix.c (scm_execl, scm_execlp, scm_execle): Cast "const char *
1147 const *" for mingw to suppress warnings from gcc (which are errors
1148 under the configure default -Werror). Reported by Nils Durner.
1150 2006-09-26 Kevin Ryde <user42@zip.com.au>
1152 * _scm.h (scm_to_off64_t, scm_from_off64_t): New macros.

1174 CSET_LETTER_PRED, CSET_DIGIT_PRED, CSET_WHITESPACE_PRED,
1175 CSET_CONTROL_PRED, CSET_HEX_DIGIT_PRED, CSET_ASCII_PRED,
1176 CSET_LETTER_AND_DIGIT_PRED, CSET_GRAPHIC_PRED, CSET_PRINTING_PRED,
1177 CSET_TRUE_PRED, CSET_FALSE_PRED, UPDATE_CSET): New macros.
1178 (define_charset, scm_srfi_14_compute_char_sets): New functions.
1179 (scm_init_srfi_14): Use `define_charset ()' instead of
1180 `define_predset ()' and `define_strset ()'.

1183 (scm_srfi_14_compute_char_sets): New declaration.
1185 * posix.h: Include "srfi-14.h".
1186 (scm_setlocale): Invoke `scm_srfi_14_compute_char_sets ()' after a
1187 successful `setlocale ()' call.
1189 2006-09-08 Kevin Ryde <user42@zip.com.au>
1191 * socket.c (scm_init_socket): Add MSG_DONTWAIT.
1192 (scm_recvfrom): Update docstring from manual.
1194 2006-08-31 Rob Browning <rlb@defaultvalue.org>
1196 * ports.c (scm_c_port_for_each): Add a
1197 scm_remember_upto_here_1(ports) at the end of the function to fix

1202 * backtrace.c (scm_display_backtrace_with_highlights): Minor
1203 improvements to docstring.
1204 (scm_backtrace_with_highlights): Analogous improvements.
1206 2006-08-12 Kevin Ryde <user42@zip.com.au>
1208 * gen-scmconfig.h.in (SCM_I_GSC_NEED_BRACES_ON_PTHREAD_ONCE_INIT):
1209 New, set from configure.
1210 * gen-scmconfig.c (SCM_NEED_BRACES_ON_PTHREAD_ONCE_INIT): New output
1212 * pthread-threads.h (SCM_I_PTHREAD_ONCE_INIT): Use
1213 SCM_NEED_BRACES_ON_PTHREAD_ONCE_INIT to cope with Solaris.
1214 Reported by Claes Wallin.
1216 2006-08-11 Neil Jerram <neil@ossau.uklinux.net>
1218 * stacks.c (scm_last_stack_frame): Correct docstring (returns a
1219 frame, not a stack).
1221 2006-07-25 Kevin Ryde <user42@zip.com.au>
1223 * threads.c (get_thread_stack_base): Restrict HAVE_PTHREAD_GETATTR_NP
1224 on pthreads version, since pthread_getattr_np not available on solaris
1225 and macos. Reported by Claes Wallin.
1227 2006-07-24 Kevin Ryde <user42@zip.com.au>
1229 * filesys.c (dirfd): Test with #ifndef rather than HAVE_DIRFD, since
1230 it's a macro on MacOS X. Reported by Claes Wallin.
1232 * posix.c (sethostname): Give prototype if not HAVE_DECL_SETHOSTNAME,
1233 for the benefit of Solaris 10. Reported by Claes Wallin.
1235 * socket.c (scm_htonl, scm_ntohl): Use scm_to_uint32 rather than
1236 NUM2ULONG, to enforce 32-bit range check on systems with 64-bit long.
1238 2006-07-21 Kevin Ryde <user42@zip.com.au>
1240 * eval.c, filesys.c (alloca): Update <alloca.h> etc blob, per current
1241 autoconf recommendation. Should fix Solaris 10 reported by Claes
1244 * threads.c: Include <string.h>, needed for memset() which is used by
1245 FD_ZERO() on Solaris 10. Reported by Claes Wallin.
1247 2006-07-18 Rob Browning <rlb@defaultvalue.org>
1249 * continuations.c: Add __attribute__ ((returns_twice)) to the
1250 ia64_getcontext prototype so that gcc will make the right
1251 arrangements and avoid an illegal instruction during
1252 call-with-current-continuation.
1254 2006-07-12 Ludovic Courtès <ludovic.courtes@laas.fr>
1256 * numbers.c (guile_ieee_init): Use regular ANSI C casts rather
1257 than C++-style `X_CAST ()'. Patch posted by by Mike Gran.
1259 2006-07-08 Kevin Ryde <user42@zip.com.au>
1261 * environments.c (core_environments_unobserve): Use if/else rather
1262 than ?: for "SET" bits, avoiding complaints from AIX xlc compiler
1263 about them not being rvalues. Reported by Mike Gran.
1265 * Makefile.am (version.h): Don't use $< in an explicit rule, it's not
1266 portable and in particular fails on OpenBSD and AIX (see autoconf
1267 manual too). Reported by Mike Gran.
1269 2006-06-25 Kevin Ryde <user42@zip.com.au>
1271 * stime.c (bdtime2c): tm_gmtoff is seconds East, so take negative of
1272 tm:gmtoff which is seconds West. Reported by Aaron VanDevender.
1273 (bdtime2c): Test HAVE_STRUCT_TM_TM_GMTOFF for tm_gmtoff, rather than
1275 (scm_strptime): Use tm_gmtoff from the strptime result when that field
1276 exists, it's set by glibc strptime "%s".
1278 2006-06-13 Ludovic Courtès <ludovic.courtes@laas.fr>
1280 * eq.c: Include "struct.h", "goops.h" and "objects.h".
1281 (scm_equal_p): Invoke `scm_i_struct_equalp ()' on structures that
1282 are not GOOPS instances.
1283 * struct.c: Include "eq.h".
1284 (scm_free_structs): Use `SCM_STRUCT_VTABLE_DATA ()' instead of
1286 (scm_i_struct_equalp): New.
1287 * struct.h (scm_i_struct_equalp): New declaration.
1289 2006-06-06 Kevin Ryde <user42@zip.com.au>
1291 * Makefile.am (BUILT_SOURCES): Remove guile.texi, only used by
1292 maintainers (with doc/maint/docstring.el). Fixes parallel "make -j2"
1293 reported by Mattias Holm.
1295 2006-06-03 Kevin Ryde <user42@zip.com.au>
1297 * read.c (s_vector): Conditionalize on SCM_ENABLE_ELISP, to avoid
1298 unused variable warning when elisp disabled. Reported by Ryan
1301 * throw.c (scm_handle_by_message): Add dummy return value to avoid
1302 compiler warning on cygwin. Reported by Ryan VanderBijl.
1304 * Makefile.am (EXTRA_DOT_X_FILES): Typo in dependency rule, was a
1305 duplicate of EXTRA_DOT_DOC_FILES.
1306 (DOT_X_FILES, EXTRA_DOT_X_FILES, DOT_DOC_FILES, EXTRA_DOT_DOC_FILES):
1307 Add scmconfig.h to dependencies, since these all run cpp. Helps a
1308 parallel "make -j2". Reported by Mattias Holm.
1310 2006-05-30 Kevin Ryde <user42@zip.com.au>
1312 * ports.c, ports.h (scm_set_port_mark, scm_set_port_free,
1313 scm_set_port_print, scm_set_port_equalp, scm_set_port_flush,
1314 scm_set_port_end_input, scm_set_port_close, scm_set_port_seek,
1315 scm_set_port_truncate, scm_set_port_input_waiting): Use scm_t_bits for
1316 port type descriptor, same as scm_make_port_type return value.
1318 2006-05-30 Marius Vollmer <mvo@zagadka.de>
1320 * eq.c (scm_equal_p): Use scm_array_equal_p explicitely when one
1321 of the arguments is a array. This allows vectors to be equal to
1322 one-dimensional arrays.
1324 2006-05-29 Marius Vollmer <mvo@zagadka.de>
1326 * throw.c (scm_ithrow): When looking for the jmpbuf, first test
1327 that we have a pair before accessing its cdr. Thanks to Bill
1330 2006-05-28 Kevin Ryde <user42@zip.com.au>
1332 * eval.c, filesys.c: Add malloc.h to get alloca() on mingw. Reported
1335 2006-05-27 Marius Vollmer <mvo@zagadka.de>
1337 * srfi-4.c, strings.c: Replace SCM_C_INLINE with
1338 SCM_C_INLINE_KEYWORD. Thanks to Mark Gran!
1340 2006-05-26 Kevin Ryde <user42@zip.com.au>
1342 * fports.c (fport_input_waiting): For ioctl, check HAVE_IOCTL as well
1343 as defined(FIONREAD), since mingw has FIONREAD but not ioctl().
1344 Reported by "The Senator".
1345 For select and ioctl, move fdes into those conditionals, to avoid
1346 unused variable warning when neither of those used.
1348 2006-05-23 Kevin Ryde <user42@zip.com.au>
1350 * fports.c: Remove "fwrite" declaration under "! HAVE_UNISTD_H".
1351 It's unused and will be in stdio.h anyway (if it's anywhere).
1353 2006-05-20 Kevin Ryde <user42@zip.com.au>
1355 * filesys.c (scm_stat2scm): Test #ifdef S_ISLNK directly, rather than
1356 HAVE_S_ISLNK from configure (it was only a #ifdef test anyway).
1358 * posix.c (scm_mknod): Test #ifdef S_IFLNK before using that (for
1359 symlink). Probably can't create symlinks with mknod anyway though.
1361 * inline.h (scm_is_pair): Add a workaround for i386 gcc 2.95 bad code
1364 2006-05-15 Kevin Ryde <user42@zip.com.au>

1367 (scm_primitive_exit): Update docstring, no longer the best exit after
1370 2006-05-09 Kevin Ryde <user42@zip.com.au>
1372 * numbers.c (scm_i_divide): For big/big wanting inexact, use mpq_get_d
1373 rather than converting to doubles, to avoid inf or nan when the inputs
1374 are too big for a double but the quotient does fit. This affects
1375 conversions exact->inexact of big fractions.
1377 * filesys.c (scm_open_fdes): Use open64.
1378 (scm_init_filesys): Add O_LARGEFILE.
1380 * ports.c (scm_seek): Use lseek64.
1381 (scm_truncate_file): Use ftruncate64.
1383 2006-05-08 Marius Vollmer <mvo@zagadka.de>
1385 * private-gc.h (CELL_P): Also check that the potential pointer is
1386 correctly aligned for a cell. Thanks to Miroslav Lichvar!
1388 2006-04-18 Rob Browning <rlb@defaultvalue.org>
1390 * _scm.h: Add back error if the size of off_t is unknown. The bug
1391 was actually in guile-readline's configuration.
1393 2006-04-18 Kevin Ryde <user42@zip.com.au>
1395 * posix.c (scm_mkstemp): Update docstring from the manual, in
1396 particular file mode 0600 is not guaranteed.
1398 2006-04-17 Kevin Ryde <user42@zip.com.au>
1400 * _scm.h (scm_to_off_t, scm_from_off_t): No error if unknown off_t
1401 size, to help the guile-readline build where off_t is unused.
1403 2006-04-16 Kevin Ryde <user42@zip.com.au>
1405 * filesys.c (scm_stat2scm, scm_stat, scm_lstat): Use stat or stat64.
1406 (scm_readdir): Use readdir64.
1407 (scm_copy_file): Use open64 and fstat64, to cope with >2Gb files.
1408 * ports.c (scm_truncate_file): Use truncate64. Correction truncate
1409 and ftruncate take off_t not size_t.
1410 * _scm.h (stat_or_stat64 etc): Macros for selecting LFS64 when
1413 2006-04-06 Kevin Ryde <user42@zip.com.au>
1415 * fports.c (scm_setvbuf): Fix for not _IOLBF, clear SCM_BUFLINE
1416 instead of toggling it. Reported by Ludovic Courtès.
1418 2006-03-26 Marius Vollmer <mvo@zagadka.de>
1420 * threads.c (get_thread_stack_base): Use scm_get_stack_base
1421 instead of accessing __libc_stack_end directly, and only do this
1422 when pthread_attr_getstack is known not to work for the main
1423 thread or when not using pthreads at all.
1425 * gc_os_dep.c (scm_get_stack_base): Abort when the machine type is
1426 unknown instead of returning NULL.
1428 2006-03-21 Ludovic Courtès <ludovic.courtes@laas.fr>
1430 * numbers.c (scm_i_mem2number): Renamed to
1431 scm_c_locale_stringn_to_number.
1432 * numbers.c, print.c, read.c: Updated callers.
1433 * numbers.h: Update function declaration.
1435 2006-03-11 Neil Jerram <neil@ossau.uklinux.net>
1437 * unif.c (string_set): Don't return in a void function. (Reported
1440 * srfi-4.c (scm_uniform_vector_read_x): Declare base as char*
1441 rather than void*, so we can do pointer arithmetic on it.
1442 (Reported by Mike Gran.)
1443 (s_scm_uniform_vector_write): Ditto.
1445 2006-03-10 Neil Jerram <neil@ossau.uklinux.net>
1447 * unif.c (scm_make_shared_array): Don't use SCM_I_ARRAY_BASE when
1448 oldra is not an array. (Reported by Steve Juranich.)
1450 * threads.c (do_unlock): Renamed from "unlock", which is defined
1451 in unistd.h on QNX. (Reported by Matt Kraai.)
1453 2006-03-04 Kevin Ryde <user42@zip.com.au>
1455 * deprecated.c (scm_i_defer_ints_etc): Show SCM_DEFER_INTS in message,
1456 not SCM_CRITICAL_SECTION_START.
1458 * eval.c, posix.c: Change comments from C++ to C style. Reported by
1461 2006-02-28 Kevin Ryde <user42@zip.com.au>
1463 * unif.c (bitvector_set): Use h->writable_elements not h->elements.
1465 2006-02-26 Kevin Ryde <user42@zip.com.au>
1467 * filesys.c (scm_readdir): Use fpathconf for the dirent size when
1468 NAME_MAX is not available, which is so on Solaris 10. Report and help
1469 by Bill Schottstaedt.
1471 * srfi-13.c (MY_VALIDATE_SUBSTRING_SPEC_UCOPY): New macro.
1472 (scm_string_compare, scm_string_compare_ci, scm_string_lt,
1473 scm_string_gt, scm_string_le, scm_string_ge, scm_string_ci_lt,
1474 scm_string_ci_gt, scm_string_ci_le, scm_string_ci_ge): In comparisons
1475 use "unsigned char", not signed char. This ensures comparisons are
1476 the same as `char<?' etc, and is also the same as guile 1.6 did.
1477 Reported by Sven Hartrumpf.
1479 2006-02-19 Mikael Djurfeldt <mdj@neurologic.cc>
1481 * random.c: Test for SCM_HAVE_T_UINT64 instead of
1483 (scm_i_uniform32, scm_i_uniform32, scm_i_init_rstate): Use
1484 scm_t_uint64 and scm_t_uint32 instead of scm_t_int64 and
1487 2006-01-04 Ludovic Courtès <ludovic.courtes@laas.fr>
1489 * gc-segment.c (scm_i_sweep_some_cards): Take a SWEEP_STATS
1490 argument. Don't refer to SCM_GC_CELLS_COLLECTED and
1491 SCM_CELLS_ALLOCATED. If SEG->FIRST_TIME, let CELLS_COLLECTED as zero.
1492 Take into account SEG->SPAN when computing CELLS_SWEPT.
1493 (scm_i_sweep_segment): Take one more argument, similarly.
1494 (scm_i_sweep_all_segments): Likewise.
1495 (scm_i_sweep_some_segments): Likewise.
1496 (scm_i_adjust_min_yield): Change the way MIN_CELLS is computed: do not
1497 refer to SCM_GC_CELLS_COLLECTED.
1499 * gc-freelist.c (scm_i_adjust_min_yield): Take one more
1500 argument, an `scm_i_sweep_statistics' object.
1501 Change the way DELTA is collected: don't take into account
1502 SCM_GC_CELLS_COLLECTED_1, only SWEEP_STATS.COLLECTED.
1504 * gc-malloc.c (scm_realloc): Pass an extra argument
1505 to `scm_i_sweep_all_segments ()'.
1507 * gc.c (gc_start_stats): Updated accordingly.
1508 (gc_end_stats): Take an additional SWEEP_STATS argument.
1509 Decrement SCM_CELLS_ALLOCATED after calls to `scm_i_sweep_* ()'.
1510 (scm_gc_for_newcell): Updated callers of `scm_i_sweep_*'.
1511 Decrement SCM_CELLS_ALLOCATED.
1512 (scm_i_gc): Likewise.
1514 * private-gc.h (scm_i_sweep_*): Updated function
1515 prototypes accordingly.
1516 (scm_t_sweep_statistics): New type.
1517 (scm_i_sweep_statistics_init): New macro.
1518 (scm_i_sweep_statistics_sum): New macro
1520 2006-02-14 Ludovic Courtès <ludovic.courtes@laas.fr>
1522 * strings.c (scm_i_take_stringbufn): Register LEN+1 bytes instead of
1523 LEN. Without this, too much collectable memory gets unregistered,
1524 which results in an underflow of SCM_MALLOCATED in
1525 `decrease_mtrigger()'.
1527 * gc-malloc.c (decrease_mtrigger): Make sure SIZE is lower than or
1528 equal to SCM_MALLOCATED.
1530 2006-02-13 Marius Vollmer <mvo@zagadka.de>
1532 * eval.c (scm_eval_body): Use scm_i_dynwind_pthread_mutex_lock
1533 oinstead of scm_dynwind_pthread_mutex_lock so that it works when
1534 configured --without-threads.
1535 (SCM_APPLY, CEVAL): Likewise. Thanks to Han-Wen Nienhuys!
1537 2006-02-12 Marius Vollmer <mvo@zagadka.de>
1539 * unif.c (scm_dimensions_to_uniform_array): Use the prototype for
1540 filling when the fill parameter is omitted, as documented, but
1541 turn #\nul into 0 since s8 arrays (signified by a #\nul prototype)
1542 can not store characters.
1544 2006-02-09 Neil Jerram <neil@ossau.uklinux.net>
1546 * socket.c (scm_c_make_socket_address): Pass address_size pointer
1547 on to scm_fill_sockaddr call.
1549 2006-02-04 Neil Jerram <neil@ossau.uklinux.net>
1551 * throw.h (scm_c_catch, scm_c_with_throw_handler,
1552 scm_catch_with_pre_unwind_handler, scm_with_throw_handler): New.
1554 * throw.c (SCM_JBPREUNWIND, SCM_SETJBPREUNWIND): New.
1555 (struct pre_unwind_data): New, replaces struct lazy_catch.
1556 (scm_c_catch): New, replaces scm_internal_catch as the primary
1557 catch API for C code; adds pre-unwind handler support.
1558 (scm_internal_catch): Now just a wrapper for scm_c_catch, for back
1560 (tc16_pre_unwind_data, pre_unwind_data_print,
1561 make_pre_unwind_data, SCM_PRE_UNWIND_DATA_P): Renamed from
1562 "lazy_catch" equivalents.
1563 (scm_c_with_throw_handler): New, replaces scm_internal_lazy_catch
1564 as the primary C API for a "lazy" catch.
1565 (scm_internal_lazy_catch): Now just a wrapper for
1566 scm_c_with_throw_handler, for back compatibility.
1567 (scm_catch_with_pre_unwind_handler): Renamed from scm_catch; adds
1568 pre-unwind handler support.
1569 (scm_catch): Now just a wrapper for
1570 scm_catch_with_pre_unwind_handler, for back compatibility.
1571 (scm_with_throw_handler): New.
1572 (scm_lazy_catch): Update comment to say that the handler can
1573 return, and what happens if it does.
1574 (toggle_pre_unwind_running): New.
1575 (scm_ithrow): When identifying the throw target, take running
1576 flags into account. In general, change naming of things from
1577 "lazy_catch" to "pre_unwind". When throwing to a throw handler,
1578 don't unwind the dynamic context first. Add dynwind framing to
1579 manage the running flag of a throw handler. If a lazy catch or
1580 throw handler returns, rethrow the same exception again. Add
1581 pre-unwind support to the normal catch case (SCM_JMPBUFP).
1583 * root.c (scm_internal_cwdr): Add NULL args to
1584 scm_i_with_continuation_barrier call.
1586 * dynwind.c: Change comment mentioning lazy-catch to mention
1587 pre-unwind data and throw handler also.
1589 * continuations.h (scm_i_with_continuation_barrier): Add
1590 pre-unwind handler args.
1592 * continuations.c (scm_i_with_continuation_barrier): Add
1593 pre-unwind handler args, and pass on to scm_c_catch (changed from
1594 scm_internal_catch).
1595 (c_handler): Remove scm_handle_by_message_noexit call.
1596 (scm_c_with_continuation_barrier): Call
1597 scm_i_with_continuation_barrier with scm_handle_by_message_noexit
1598 as the pre-unwind handler.
1599 (scm_handler): Remove scm_handle_by_message_noexit call.
1600 (s_scm_with_continuation_barrier): Call
1601 scm_i_with_continuation_barrier with scm_handle_by_message_noexit
1602 as the pre-unwind handler.
1604 2006-02-04 Kevin Ryde <user42@zip.com.au>
1606 * gc-mark.c (scm_mark_all): Fix c99-isms "loops" and "again" variables.
1608 2006-02-03 Kevin Ryde <user42@zip.com.au>
1610 * list.c, list.h (scm_list): Restore this function for use from C.
1611 It's a complete no-op but in theory might used by someone.
1613 2006-01-30 Marius Vollmer <mvo@zagadka.de>
1615 * eval.c (scm_eval_body): Lock source_mutex with a dynwind context
1616 so that it gets unlocked in all cases.
1617 (SCM_APPLY, CEVAL): Likewise.
1619 2006-01-29 Marius Vollmer <mvo@zagadka.de>
1621 * ramap.c: (scm_array_map_x): Don't use scm_array_p, use
1622 scm_is_typed_array instead.
1624 Renamed the "frames" that are related to dynamic-wind to "dynamic
1625 contexts. Renamed all functions from scm_frame_ to scm_dynwind_.
1626 Updated documentation.
1630 * futures.h, futures.c: Wrap whole contents in "#if 0"/"#endif".
1631 * eval.c, init.c: Comment out all 'future' related things.
1633 2006-01-28 Marius Vollmer <mvo@zagadka.de>
1635 * inline.h, pairs.c (scm_is_pair): Moved scm_is_pair from pairs.c
1636 to inline.h to make it inline.
1638 2005-12-19 Ludovic Courtès <ludovic.courtes@laas.fr>
1640 * strings.c (scm_i_take_stringbufn): New.
1641 (scm_i_c_take_symbol): New.
1642 (scm_take_locale_stringn): Use `scm_i_take_stringbufn ()'.
1644 * strings.h (scm_i_c_take_symbol): New.
1645 (scm_i_take_stringbufn): New.
1647 * symbols.c (lookup_interned_symbol): New function.
1648 (scm_i_c_mem2symbol): New function.
1649 (scm_i_mem2symbol): Use `lookup_symbol ()'.
1650 (scm_from_locale_symbol): Use `scm_i_c_mem2symbol ()'. This avoids
1651 creating a new Scheme string.
1652 (scm_from_locale_symboln): Likewise.
1653 (scm_take_locale_symbol): New.
1654 (scm_take_locale_symboln): New.
1656 * symbols.h (scm_take_locale_symbol): New.
1657 (scm_take_locale_symboln): New.
1659 2006-01-18 Han-Wen Nienhuys <hanwen@xs4all.nl>
1661 * gc-card.c ("sweep_card"): don't count scm_tc_free_cell for
1664 2005-11-29 Han-Wen Nienhuys <hanwen@xs4all.nl>
1666 * regex-posix.c (s_scm_regexp_exec): list the offending pattern
1669 2005-12-29 Neil Jerram <neil@ossau.uklinux.net>
1671 * fluids.c (next_fluid_num): [From Ludovic Courtès:] Don't trigger
1672 the GC when allocated_fluids_len is zero.
1674 2005-12-14 Neil Jerram <neil@ossau.uklinux.net>
1676 * load.c (the_reader, the_reader_fluid_num): New.
1677 (scm_primitive_load): Support custom reader.
1678 (scm_init_load): Init the_reader and the_reader_fluid_num; export
1679 the_reader as `current-reader'.
1681 * scmsigs.c (do_read_without_guile): Use the "raw_data" passed in
1682 (rather than an uninitialized pointer on the stack).
1684 2005-12-07 Marius Vollmer <mvo@zagadka.de>
1686 Reported by Bruce Korb:
1688 * init.c (invoke_main_func): Don't call exit here. Throws that
1689 are only caught by scm_with_guile will bypass us and would cause
1690 scm_boot_guile to return erroneously.
1691 (scm_boot_guile): Expect scm_with_guile to return and call exit
1692 here, passing it an appropriate exit code.
1696 * script.c (scm_find_executable): Compile fix -- fgetc returns an
1697 unsigned char cast to an int, or -1 for EOS.
1699 2005-12-06 Marius Vollmer <mvo@zagadka.de>
1701 * srfi-4.h, srfi-4.c, srfi-4.i.c (take_uvec): Make BASE pointer
1703 (scm_take_u8vector, etc): Likewise. Thanks to Ludovic Courtès!
1705 * threads.h, threads.c (scm_t_guile_ticket, scm_leave_guile,
1706 scm_enter_guile): Removed from public API. See comment at
1707 scm_without_guile for the rationale.
1709 * scmsigs.c (read_without_guile): New.
1710 (signal_delivery_thread): Use it instead of
1711 scm_leave_guile/read/scm_enter_guile.
1713 From Stephen Compall:
1715 * eval.c (scm_m_cond): Recognize SRFI 61 cond syntax.
1716 (CEVAL): Evaluate SRFI 61 cond clauses.
1718 2005-12-06 Ludovic Courtès <ludovic.courtes@laas.fr>
1720 * gc-card.c (scm_i_card_statistics): Return if BITVEC is NULL.
1721 This was typically hit when running `gc-live-object-stats' right
1722 after starting Guile.
1724 2005-11-30 Kevin Ryde <user42@zip.com.au>
1726 * srfi-13.c (scm_string_append_shared): No copying if just one
1727 non-empty string in args.
1729 2005-11-26 Kevin Ryde <user42@zip.com.au>

1734 * list.c (list): Should be "primitive" in SCM_SNARF_DOCS, not
1737 * random.c (scm_i_copy_rstate, scm_c_make_rstate): Don't test for
1738 scm_malloc returning NULL, it never does that.
1739 * putenv.c (putenv): Likewise.
1741 * socket.c (scm_fill_sockaddr): Remove SCM_C_INLINE_KEYWORD, this is
1742 much too big to want to inline.
1744 2005-11-17 Ludovic Courtès <ludovic.courtes@laas.fr>
1746 * print.c (EXIT_NESTED_DATA): Before popping from the stack, reset
1747 the value at its top. This fixes a reference leak.
1748 (PUSH_REF): Perform `pstate->top++' after calling
1749 `PSTATE_STACK_SET ()' in order to avoid undesired potential side
1752 2005-11-12 Ludovic Courtès <ludovic.courtes@laas.fr>
1754 * gc.c (scm_weak_vectors): Removed.
1756 2005-11-12 Kevin Ryde <user42@zip.com.au>
1758 * socket.c (scm_setsockopt): Missing @defvar in docstring. Reported
1761 2005-11-07 Marius Vollmer <mvo@zagadka.de>
1763 * stime.c (scm_mktime): Use scm_frame_critical_section instead of
1764 SCM_CRITICAL_SECTION_START/END since the code inside the critical
1765 section might exit non-locally.
1767 2005-11-04 Neil Jerram <neil@ossau.uklinux.net>
1769 * eval.c (sym_instead): New symbol.
1770 (ENTER_APPLY): Remove optional use of a continuation when making
1772 (scm_debug_opts): Change doc for 'cheap option to make clear that
1774 (CEVAL, SCM_APPLY): Remove optional use of a continuation when
1775 making trap calls, and implement substitution of eval expressions
1776 and return values using the values that the trap call handlers
1779 * debug.h (SCM_CHEAPTRAPS_P): Removed.
1781 2005-10-27 Ludovic Courtès <ludovic.courtes@laas.fr>
1783 * socket.c (scm_fill_sockaddr): No need to check NULL from scm_malloc.
1784 (scm_connect, scm_bind, scm_sendto): Accept sockaddr object.
1785 (scm_addr_vector): Renamed to _scm_from_sockaddr, update usages.
1786 (scm_from_sockaddr, scm_to_sockaddr, scm_make_socket_address,
1787 scm_c_make_socket_address): New functions.
1788 * socket.h: Add prototypes.
1790 2005-10-24 Kevin Ryde <user42@zip.com.au>
1792 * socket.c (scm_init_socket): Add IPPROTO_IP, IPPROTO_TCP,
1793 IPPROTO_UDP. Remove SOL_IP, SOL_TCP, SOL_UDP. The former are in
1794 POSIX spec examples, the latter are not available on for instance
1797 * socket.c (scm_getsockopt, scm_setsockopt): Update docstrings from
1800 * stime.c (scm_strftime): Update docstring from posix.texi.
1802 2005-10-23 Marius Vollmer <marius.vollmer@uni-dortmund.de>
1804 PTHREAD_RECURSIVE_MUTEX_INITIALIZER_NP is not portable enough.
1806 * null-threads.h, pthread-threads.h
1807 (SCM_I_PTHREAD_RECURSIVE_MUTEX_INITIALIZER): Removed.
1808 (scm_i_pthread_mutexattr_recursive): New.

1812 (scm_threads_prehistory): Initialize
1813 scm_i_pthread_mutexattr_recursive and scm_i_critical_section_mutex
1816 * eval.c (source_mutex): Do not initialiaze statically.
1817 (scm_init_eval): Do it here, using
1818 scm_i_pthread_mutexattr_recursive.
1820 2005-09-05 Marius Vollmer <mvo@zagadka.de>
1822 * print.h (SCM_PRINT_KEYWORD_STYLE_I, SCM_PRINT_KEYWORD_STYLE):
1825 (scm_print_opts): Added "quote-keywordish-symbols" option.
1826 (quote_keywordish_symbol): New, for evaluating the option.
1827 (scm_print_symbol_name): Use it.
1828 (scm_init_print): Initialize new option to sym_reader.
1830 2005-08-15 Neil Jerram <neil@ossau.uklinux.net>
1832 * eval.c (eval_letrec_inits): New.
1833 (CEVAL): Eval letrec initializer forms using eval_letrec_inits.
1835 2005-08-12 Marius Vollmer <mvo@zagadka.de>

1848 scm_string_index, scm_string_index_right, scm_string_skip,
1849 scm_string_skip_right, scm_string_count, scm_string_map,
1850 scm_string_map_x, scm_string_for_each, scm_string_for_each_index,
1851 scm_string_filter, scm_string_delete): Use scm_t_trampoline_1 for
1852 procedures called in loops.
1854 2005-08-02 Kevin Ryde <user42@zip.com.au>
1856 * strports.c (st_flush): Increase buffer by 1.5x when growing, to
1857 avoid lots of copying where previoulsy growing by only 80 bytes at a
1860 2005-08-01 Marius Vollmer <mvo@zagadka.de>
1862 * modules.h, modules.c (scm_eval_closure_module): Removed, we
1863 already have scm_lookup_closure_module, which does the same thing.
1865 2005-08-01 Marius Vollmer <mvo@zagadka.de>
1867 New marking algorithm for weak hashtables that fixes the problem
1868 that references from the non-weak value to the associated weak
1869 key (for example) would prevent the entry from ever being dropped.
1871 Guardians have been changed back to their original semantics and
1872 are no longer greedy and no longer drop cycles.
1874 * gc-mark.c (scm_mark_all): Do not rely on hooks to run the weak
1875 hashtable and guardian machinery but call the relevant functions
1878 * guardians.h, guardians.c, deprecated.h,
1879 deprecated.c (scm_destroy_guardian_x, scm_guardian_greedy_p,
1880 scm_guardian_destroyed_p, scm_guard, scm_get_one_zombie):
1881 Deprecated and moved into deprecated.[ch].
1883 * guardians.h, guardians.c: Mostly rewritten.

1892 (scm_weaks_prehistory): Removed.
1893 (scm_i_init_weak_vectors_for_gc, scm_i_mark_weak_vector,
1894 scm_i_mark_weak_vectors_non_weaks,
1895 scm_i_remove_weaks_from_weak_vectors, scm_i_remove_weaks): New.
1896 (scm_weak_vector_gc_init, scm_mark_weak_vector_spines,

1902 (hashtable_print): Use SCM_HASHTABLE_N_ITEMS instead of
1904 (scan_weak_hashtables, scm_i_scan_weak_hashtables): Renamed former
1905 to latter. Do not scan the alists themselves, this is done by the
1906 weak vector code now. Just update the element count.
1908 * vectors.h (SCM_I_WVECT_TYPE, SCM_I_WVECT_EXTRA): Renamed former
1909 to latter. The type is now only part of the cell word.
1910 (SCM_I_SET_WVECT_TYPE, SCM_I_SET_WVECT_EXTRA): Likewise.
1912 * init.c (scm_i_init_guile): Do not call scm_weaks_prehistory.
1914 2005-07-18 Mikael Djurfeldt <mdj@d14n36.pdc.kth.se>
1916 Some changes towards making it possible to run Guile on the EM64T
1919 * gc.c (scm_gc_stats): Bugfix: Measure size of the type we are
1920 mallocating for (unsigned long *bounds).
1922 * hashtab.c (scm_i_rehash): Cast SCM_HASHTABLE_FLAGS (table) to
1923 scm_t_bits before storing them in the type word.
1925 * gc.c (tag_table_to_type_alist): Modified type of c_tag from
1928 2005-07-12 Kevin Ryde <user42@zip.com.au>
1930 * eval.c (scm_dbg_make_iloc): Should be SCM_IFRAMEMAX and
1931 SCM_IDISTMAX, and cast uints through scm_t_bits to make gcc happy.
1932 * pairs.c (scm_error_pair_access): Use scm_from_locale_string rather
1933 than scm_makfrom0str.
1934 Reported by Ken Raeburn.
1936 * gc-card.c (scm_dbg_gc_get_bvec): Change return from long* to
1937 scm_t_c_bvec_long*, gcc 4 doesn't like different pointer targets when
1938 returning SCM_GC_CARD_BVEC.
1940 * pairs.c (scm_error_pair_access): Plain ascii ' in error message
1941 rather than latin-1 acute accent, the latter may not print on all
1944 * srfi-13.c (scm_string_filter, scm_string_delete): Strip leading and
1945 trailing deletions, so as to return a substring if those are the only
1948 2005-07-10 Kevin Ryde <user42@zip.com.au>
1950 * socket.c (scm_inet_pton, scm_inet_ntop): Pointer cast to scm_t_uint8
1951 for scm ipv6 funcs, gcc 4 is picky about char* vs uchar*.
1952 (scm_getsockopt, scm_accept, scm_getsockname, scm_getpeername,
1953 scm_recvfrom) Use socklen_t, gcc 4 is picky about int* vs socklen_t*.
1955 2005-07-01 Han-Wen Nienhuys <hanwen@xs4all.nl>
1957 * gc-card.c (scm_i_card_statistics): init tag.
1959 * gc.c (tag_table_to_type_alist): check type of tag. Should be integer.
1961 2005-06-18 Han-Wen Nienhuys <hanwen@xs4all.nl>
1963 * fports.c (s_scm_open_file): add the b flag for binary to the doc
1966 2005-06-25 Kevin Ryde <user42@zip.com.au>
1968 * srfi-13.c (scm_string_filter, scm_string_delete): Partial revert
1969 last change, use plain copy-on-write substrings, the individual
1970 descriptions in the srfi don't mention shared storage (only the
1973 * strings.c (scm_take_locale_stringn): Use realloc to make room for
1974 null-terminator, rather than mallocing a whole new block.
1975 (scm_take_locale_string): Use scm_take_locale_stringn len==-1.
1977 2005-06-12 Marius Vollmer <mvo@zagadka.de>
1979 * ramap.c (scm_array_index_map_x): First test for real arrays,
1980 then check for generalized vectors. This ensures that the
1981 generalized vector case need only work with zero-origin ranges.
1982 (scm_ra_eqp, scm_ra_compare): Use the new array handle functions
1983 to access the target array, making these functions work with all
1984 kinds of arrays, not just bit arrays.
1986 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,

1998 table. This means that procedure properties are GC'd if the
2001 2005-06-11 Kevin Ryde <user42@zip.com.au>
2003 * srfi-13.c (scm_string_filter, scm_string_delete): For char and
2004 charset cases, count chars kept and build a string in a second pass,
2005 rather than using a cons cell for every char kept. Use a shared
2006 substring when nothing removed (such sharing is allowed by the srfi).

2015 * print.c (iprin1): When writing a string, collect all characters
2016 that can be printed directly into one call to scm_lfwrite.
2017 Previously, every character was output with its own call to
2018 write(2) on unbuffered ports.
2020 * eval.c (scm_eval_options_interface): Use
2021 scm_frame_critical_section instead of SCM_CRITICAL_SECTION_START
2022 and SCM_CRITICAL_SECTION_END.
2024 * unif.c (scm_array_in_bounds_p): First test for real arrays, then
2025 check for generalized vectors. This ensures that the generalized
2026 vector case need only work with zero-origin ranges.
2028 2005-06-06 Kevin Ryde <user42@zip.com.au>
2030 * srfi-13.c (scm_string_split): Compare char/char in scan. Mixing an
2031 unsigned int SCM_CHAR and a char string meant an 8-bit char was never
2034 2005-06-05 Marius Vollmer <mvo@zagadka.de>
2036 * eval.c: Added comment on how to make case 1.1 of
2037 r5rs_pitfall.test succeed.
2039 From Jan Nieuwenhuizen <janneke@gnu.org>. Thanks!

2112 SCM_DEBUG_CELL_ACCESSES
2113 (FLUID_NEXT_LOC): idem.
2115 2005-04-30 Kevin Ryde <user42@zip.com.au>
2117 * numbers.c (scm_divide): Correction to 1/complex and <any>/complex,
2118 need to test abs(re)<abs(im) for choice of cases, otherwise divide by
2119 zero when re==0 and im<0. Reported by Jean Crepeau.
2121 2005-04-25 Kevin Ryde <user42@zip.com.au>
2123 * ramap.c (scm_array_map_x): Allow no source args, add num args checks
2124 to subr_1, subr_2, subr_2o and dsubr cases. No source args only has a
2125 few sensible uses (like filling with a random number generator say),
2126 but has been allowed in the past and so should be kept.
2128 2005-04-23 Kevin Ryde <user42@zip.com.au>
2130 * hashtab.c (scm_hashx_remove_x): Need to pass "closure" to
2131 scm_hash_fn_remove_x.
2133 * list.c (scm_cons_star): Don't modify the rest list, it belongs to
2134 the caller when cons* is reached through apply.
2136 * list.c (list): Use scm_list_copy, so as to produce a fresh list when
2137 list is called using apply, under the debugging evaluator.

2146 converted from scheme code in boot-9.scm.
2148 2005-04-11 Kevin Ryde <user42@zip.com.au>
2150 * srfi-13.c (scm_string_concatenate, scm_string_concatenate_shared):
2151 Validate list argument, scm_string_append and scm_string_append_shared
2152 don't do that to their rest argument (in a normal build).
2154 2005-04-04 Marius Vollmer <marius.vollmer@uni-dortmund.de>
2156 * hashtab.h, hashtab.c (scm_t_hashtable): Removed 'closure' field. The
2157 closure can not be stored since it is no longer valid at GC time.
2158 (make_hash_table): Initialize 'hash_fn' field.
2159 (scm_i_rehash): Only store hash_fn in hash table when closre is
2161 (rehash_after_gc): Only call scm_i_rehash when 'hash_fn' is
2162 non-NULL. Always use a NULL closure.
2163 (scm_hash_fn_create_handle_x): Also rehash when table contains too
2166 2005-03-29 Marius Vollmer <marius.vollmer@uni-dortmund.de>
2168 * hashtab.h, hashtab.c (scm_hash_fx_remove_x): Removed delete_fn
2169 argument; always use scm_delq_x. The delete_fn function works on
2170 the handle, not the key, and it therefore makes no sense to make
2171 it configurable. Changed all callers.
2172 (scm_hashx_remove_x): Likewise. Also, exported to Scheme.
2173 (scm_hash_clear): Accept plain vectors as hashtables.
2174 (scm_delx_x): Removed.
2176 2005-03-28 Han-Wen Nienhuys <hanwen@xs4all.nl>
2178 * inline.h (scm_double_cell): use __asm__ iso. asm, to maintain
2179 compatibility with gcc -std=c99.

2206 2005-03-13 Kevin Ryde <user42@zip.com.au>
2208 * numbers.c, numbers.h (scm_i_clonebig): Remove static, so can use in
2211 * numbers.c (scm_logior): Must scm_i_normbig results as per scm_logand,
2212 because OR-ing bits into a negative can reduce the value to an inum.
2214 * numbers.c (scm_num_eq_p): On 64-bit systems, be careful about
2215 casting inum to double since that can lose precision.
2217 2005-03-10 Marius Vollmer <marius.vollmer@uni-dortmund.de>
2219 * threads.h, threads.c (scm_i_thread): Added gc_running_p field.

2226 (scm_i_sweep_mutex): Now a non-recursive mutex. GC can not happen
2228 (scm_igc, scm_i_gc): Renamed former to latter. Changed all uses.
2229 Do not lock scm_i_sweep_mutex, which is now non-recursive, or set
2230 scm_gc_running_p. Do not run the scm_after_gc_c_hook.
2231 (scm_gc): Lock scm_i_sweep_mutex, set scm_gc_running_p and run the
2232 scm_after_gc_c_hook here.
2233 (scm_gc_for_new_cell): Set scm_gc_running_p here and run the
2234 scm_after_gc_c_hook when a full GC has in fact been performed.
2235 (scm_i_expensive_validation_check): Call scm_gc, not scm_i_gc.
2237 * gc-segment.c (scm_i_get_new_heap_segment): Do not check
2240 * gc-malloc.c (scm_realloc, increase_mtrigger): Set
2241 scm_gc_running_p while the scm_i_sweep_mutex is locked.
2243 * inline.h (scm_cell, scm_double_cell): Do not check
2244 scm_gc_running_p, allocation during sweeping is OK.
2246 * gdbint.c (SCM_BEGIN_FOREIGN_BLOCK, SCM_END_FOREIGN_BLOCK): Do
2247 not set scm_block_gc.
2249 * init.c (scm_i_init_guile): Do not set scm_block_gc.

2267 * threads.h, threads.c (scm_i_frame_single_threaded): Removed.
2268 (scm_i_thread): Removed unused signal_asyncs field.

2284 simple things inside that region.
2285 (scm_make_fluid, scm_make_dynamic_state): Lock fluid_admin_mutex
2286 while adding to the global lists.
2289 2005-03-08 Marius Vollmer <mvo@zagadka.de>
2291 libltdl is no longer distributed. We expect it to be installed
2294 * Makefile.am (INCLUDES): Removed @LTDLINCL@.
2295 (libguile_la_LIBADD): Removed @LIBLTDL@.

2300 SCM_CRITICAL_SECTION_END): Moved here from threads.h since now
2301 they also block/unblock execution of asyncs and call
2302 scm_async_click which is declared in async.h but threads.h can not
2303 include async.h since async.h already includes threads.h.
2304 (scm_i_critical_section_level): New, for checking mistakes in the
2305 use of the SCM_CRITICAL_SECTION_* macros.
2306 (scm_i_critical_section_mutex): Make it a recursive mutex so that
2307 critical sections can be nested.

2326 scm_frame_critical_section.
2328 * continuations.c (scm_make_continuation): No longer a critical

3194 Enclosed arrays are now their own smob. This has been done to
3195 make the code more explicit about them and to prepare for the time
3196 when generalized vectors include arbitrary one-dimensional
3197 arrays. (Uptonow, enclosed arrays have been recognized by their
3198 use of an array as their storage 'vector'. When all generalized
3199 vectors are allowed as storage, including one-dimensional arrays,
3200 this will no longer work.)

3244 * ramap.c (cind): Changed second arg to be pointer to long instead
3246 (scm_ramapc): Allocate index vector with scm_malloc and not as
3247 uniform vector. Wrap it in a frame so that it gets properly freed.
3248 (scm_array_index_map_x): Likewise.
3250 * unif.c: Changed all uses of scm_array_prototype to

3467 First cut at integrating uniform vectors from srfi-4 with the rest
3468 of Guile. This change replaces scm_tc7_byvect with a s8 uniform

3862 2004-09-06 Kevin Ryde <user42@zip.com.au>
3864 * stime.h (SCM_TIME_UNITS_PER_SECOND): Use sysconf(_SC_CLK_TCK) when
3865 available. This also gets around CLK_TCK being absent when
3866 _GNU_SOURCE and _POSIX_C_SOURCE are defined in stime.c.
3868 2004-09-03 Stefan Jahn <stefan@lkcc.org>
3870 * threads.c (scm_threads_mark_stacks): Fixed local variable
3873 * strings.c (scm_i_substring_copy, scm_string_append): Fixed
3874 local variable definitions.
3876 * stime.c (_POSIX_C_SOURCE): Do not define this item on
3877 MinGW32 because it conflicts with its pthread headers.
3878 (scm_mktime): Consider the HAVE_STRUCT_TM_TM_ZONE define.
3879 (scm_strftime): Using scm_from_locale_string() instead of
3882 * posix.c (scm_putenv): Fixed typo in the !HAVE_UNSETENV
3885 * numbers.c (scm_init_numbers): Removed check_sanity() call
3886 inside GUILE_DEBUG. The function has been removed somewhen...
3888 * filesys.c (_POSIX_C_SOURCE): Do not define this item on
3889 MinGW32 because it conflicts with its pthread headers.
3891 2004-08-27 Marius Vollmer <marius.vollmer@uni-dortmund.de>
3893 * strings.c (SCM_STRINGP): Accept all strings.
3894 (SCM_STRING_CHARS): Reject shared substrings here.
3896 * script.c (scm_compile_shell_switches): Added 2003 and 2004 to
3897 the Copyright years.

3902 HAVE_STRUCT_SOCKADDR_IN6_SIN6_LEN for sockaddr fields, SIN_LEN and
3903 SIN_LEN6 are not defined on all systems. Reported by Michael Tuexen.
3905 2004-08-26 Marius Vollmer <marius.vollmer@uni-dortmund.de>
3907 * strings.h, strings.c (scm_i_make_symbol): Added FLAGS parameter.

3912 2004-08-25 Marius Vollmer <marius.vollmer@uni-dortmund.de>
3914 * srfi-13.c: First cut at thread-safeness and proper use of
3915 scm_i_string_chars et al. Copious scm_remember_upto_heres have
3916 been inserted. Made sure that no internal string pointer is used
3917 across a SCM_TICK or a possible GC.
3919 * script.c (scm_compile_shell_switches): Use
3920 scm_from_locale_string instead of scm_makfrom0str.
3922 * srfi-13.c (scm_string_rindex): Export to Scheme, as it has
3925 2004-08-25 Marius Vollmer <mvo@zagadka.de>

3930 * srfi-13.c, srfi-13.h, srfi-14.c, srfi-14.h: New files.
3931 * strop.h, strop.c: Removed, they are now empty.
3932 * Makefile.am: Updated for new and removed files.
3934 * symbols.h, symbols.c (scm_string_ci_to_symbol): Moved here, next
3935 to scm_string_to_symbol.
3937 * chars.c (scm_char_alphabetic_p, scm_char_numeric_p,
3938 scm_char_whitespace_p, scm_upper_case_p, scm_lower_case_p,
3939 scm_char_is_both_p): Use scm_char_set_contains_p with the proper
3940 charset instead of libc functions.
3942 * strorder.c (scm_string_equal_p, scm_string_ci_equal_p,
3943 scm_string_less_p, scm_string_leq_p, scm_string_gr_p,
3944 scm_string_geq_p, scm_string_ci_less_p, scm_string_ci_leq_p,
3945 scm_string_ci_gr_p, scm_string_ci_geq_p): Use scm_string_eq, etc
3946 instead of explicit code.
3948 * deprecated.c, load.c, posix.c, unif.c, symbols.c: Include
3949 "srfi-13.h" instead of "strop.h".
3951 * init.c (scm_init_guile_1): Call scm_init_srfi_13 and
3952 scm_init_srfi_14. Do not call scm_init_strop.

3956 * numbers.c (scm_inf_p): Synced docstring back from manual.
3958 2004-08-22 Marius Vollmer <mvo@zagadka.de>

3962 scm_i_string_char, scm_i_string_writable_chars): Use it.
3963 (scm_i_substring_copy): Make START argument optional for C
3964 callers, for upcoming SRFI-13 integration.
3966 2004-08-21 Marius Vollmer <mvo@zagadka.de>
3968 From Richard Todd, Thanks!
3970 * script.c (scm_compile_shell_switches): added '-L' switch to add

3976 from the output during unmemoization, also drop those that are not
3977 immediately at the beginning of a body.
3979 2004-08-20 Marius Vollmer <marius.vollmer@uni-dortmund.de>
3981 * eval.c (scm_lookupcar1): Report "Variable used before given a
3982 value" insetad of an "Unbound" one for variables that are found
3983 but still contain SCM_UNDEFINED.
3985 * posix.c (scm_mkstemp): Correction to the correction, mkstemp
3986 expects a null-terminated string in the locale encoding, but
3987 scm_i_string_writable_chars doesn't give that. Fixed by letting
3988 mkstemp modify a locale version of the tmpl argument and copying
3989 the result back into tmpl.
3991 * strop.c (scm_substring_move_x): Store into str2, not str1.
3993 2004-08-20 Kevin Ryde <user42@zip.com.au>

4006 New string implementation, with copy-on-write strings and
4007 mutation-sharing substrings, and a new internal string API.
4008 Symbols can now share memory with strings.
4010 * tags.h (scm_tc7_stringbuf): New tag.

4031 scm_str2symbol, scm_mem2uninterned_symbol): Discouraged.
4032 (SCM_SYMBOL_LENGTH, SCM_SYMBOL_CHARS, scm_c_symbol2str):
4034 (SCM_MAKE_SYMBOL_TAG, SCM_SET_SYMBOL_LENGTH, SCM_SET_SYMBOL_CHARS,
4035 SCM_PROP_SLOTS, SCM_SET_PROP_SLOTS): Removed.

4037 New, to replace scm_str2symbol and scm_mem2symbol, respectively.
4039 (scm_gensym): Generate only the number suffix in the buffer, just
4040 string-append the prefix.
4042 * error.c (scm_memory_error): Do not try to throw, just abort.
4043 Throwing will not work anyway.
4045 * gh.h, gh-data.c (gh_set_substr): Made src const.

4048 (scm_mode_bits): Use it.
4049 (scm_c_port_for_each): Blocking GC does not seem to work, allocate
4050 a vector normally and fill that instead of consing a list with a
4053 * read.c (scm_i_casei_streq): New, for counted strings.
4055 * threads.c (gc_section_count): Removed, thread-sleeping can not
4057 (scm_i_thread_put_to_sleep): Call scm_i_leave_guile before locking
4058 admin mutex so that we can be put to sleep by other threads while
4059 blocking on that mutex. Lock all the heap mutex of all threads,
4060 including ourselves.
4061 (scm_i_thread_wake_up): Unlock all threads, including ourselves,
4062 call scm_i_enter_guile.
4063 (scm_thread_mark_stacks): Expect all threads to be suspended.

4066 scm_gc_mallocated, for now.
4067 (scm_init_storage): Initialize it.
4068 * gc-malloc.c (descrease_mtrigger, increase_mtrigger): Use it.
4070 * gc-mark.c (scm_gc_mark_dependencies): Call scm_i_string_mark,
4071 scm_i_stringbuf_mark and scm_i_symbol_mark, as appropriate.
4072 * gc-card.c (scm_i_sweep_card): Call scm_i_string_free,
4073 scm_i_stringbuf_free and scm_i_symbol_free, as appropriate.
4075 * strop.c (scm_string_copy): Use scm_c_substring to get a
4076 copy-on-write string.
4078 2004-08-18 Kevin Ryde <user42@zip.com.au>
4080 * arbiters.c (FETCH_STORE): New macro.
4081 (SCM_LOCK_VAL, SCM_UNLOCK_VAL): New constants.
4082 (SCM_LOCK_ARB, SCM_UNLOCK_ARB): Remove, effectively absorbed into
4083 scm_try_arbiter and scm_release_arbiter.
4084 (scm_try_arbiter, scm_release_arbiter): Use FETCH_STORE to get xchg
4085 for speed on i386, otherwise using mutex.
4087 * eq.c (scm_equal_p): Remove real==fraction and fraction==real, they
4088 must be #f according to R5RS. (equal? follows eqv?, and for eqv? an
4089 exact and inexact is #f.)
4091 * fports.c (fport_print): Use scm_ttyname instead of ttyname directly,
4092 to get thread safety of scm_ttyname.
4094 * ports.c (ttyname): Remove prototype, unused.
4096 * socket.c (scm_init_socket): Add SOCK_SEQPACKET and SOCK_RDM.
4097 Reported by Michael Tuexen.
4099 2004-08-13 Marius Vollmer <marius.vollmer@uni-dortmund.de>
4101 * load.c (scm_init_load_path): Do not pass NULL to
4102 scm_to_locale_string, which would happen when GUILE_LOAD_PATH is
4103 not set. Thanks to Bill Schottstaedt.
4105 2004-08-12 Marius Vollmer <marius.vollmer@uni-dortmund.de>
4107 * socket.c (scm_inet_aton, scm_inet_pton): Convert SCM strings to
4108 locale strings instead of accessing their internals.

4111 SCM_STRING_CHARS and SCM_STRING_LENGTH.
4113 * simpos.c (scm_system): Convert SCM strings to locale strings
4114 instead of accessing their internals.
4116 * script.c (scm_compile_shell_switches): Convert version to locale
4117 string before printing it.
4119 * rdelim.c (scm_read_delimited_x): Avoid
4120 SCM_VALIDATE_SUBSTRING_SPEC_COPY and use scm_from_size_t instead
4121 of scm_from_long for the returned number of read characters.
4123 * ioext.c (scm_fdopen): Use scm_i_fdes_to_port together with
4124 scm_i_mode_bits to avoid accessing internals of SCM string from C.
4126 * filesys.c (STRING_SYSCALL, STRING2_SYSCALL): New helper macros.
4127 Use them instead of SCM_SYSCALL when one or two strings need to be
4128 converted into locale strings.
4129 (my_rename): New, gathers platform dependent code for renaming.
4130 (scm_rename): Use it.
4131 (scm_readlink, scm_copy_file): Convert SCM strings to locale
4132 strings instead of accessing their internals.
4133 (scm_basename, scm_dirname): Use SCM_I_STRING_CHARS and
4134 SCM_I_STRING_LENGTH instead of SCM_STRING_CHARS and
4137 * extensions.c (load_extension): Convert lib and init to locale
4138 strings instead of accessing the internals directly.
4139 (scm_c_load_extension): Use scm_from_locale_string instead of
4142 * fports.h, fports.c (scm_i_fdes_to_port): New, like
4143 scm_fdes_to_port, but take mode bits directly instead of as a C
4145 (scm_i_fdes_to_port): Implement using above.
4146 (scm_open_file): Use scm_i_fdes_to_port together with
4147 scm_i_mode_bits to avoid accessing internals of SCM string from C.
4148 * vports.c (scm_make_soft_port): Use scm_i_fdes_to_port together
4149 with scm_i_mode_bits to avoid accessing internals of SCM string
4152 * ports.h (scm_i_mode_bits): New, same as scm_mode_bits but with a
4153 SCM string as argument.
4155 * ports.c (scm_i_void_port): New, like scm_void_port but take mode
4156 bits directly instead of C string.
4157 (scm_void_port): Implement using above.
4158 (scm_sys_make_void_port): Use scm_i_void_port together with
4159 scm_i_mode_bits to avoid accessing internals of SCM string.
4161 * strings.h, strings.c (scm_i_get_substring_spec): New.
4163 * socket.c, rw.c, deprecated.h, validate.h
4164 (SCM_VALIDATE_STRING_COPY): Deprecated. Replaced all uses with
4165 SCM_VALIDATE_STRING plus SCM_I_STRING_CHARS or
4166 scm_to_locale_string, etc.
4167 (SCM_VALIDATE_SUBSTRING_SPEC_COPY): Deprecated. Replaced as
4168 above, plus scm_i_get_substring_spec.
4170 * regex-posix.c, read.c, random.c, ramap.c, print.c, numbers.c,
4171 hash.c, gc.c, gc-card.c, convert.i.c, backtrace.c, strop.c,
4172 strorder.c, strports.c, struct.c, symbols.c, unif.c, ports.c: Use
4173 SCM_I_STRING_CHARS, SCM_I_STRING_UCHARS, and SCM_I_STRING_LENGTH
4174 instead of SCM_STRING_CHARS, SCM_STRING_UCHARS, and
4175 SCM_STRING_LENGTH, respectively. Also, replaced scm_return_first
4176 with more explicit scm_remember_upto_here_1, etc, or introduced
4177 them in the first place.
4179 * posix.c (WITH_STRING): New helper macro. Use it where one
4180 locale string is needed for a short piece of code.
4181 (STRING_SYSCALL): New helper macro. Use it instead of SCM_SYSCALL
4182 when one locale string is needed.
4183 (scm_mkstemp): Convert tmpl to a locale string.
4184 (scm_putenv): Rewritten to use only C strings.
4185 (scm_setlocale, scm_crpt): Convert argument strings to locale
4188 2004-08-11 Marius Vollmer <marius.vollmer@uni-dortmund.de>
4190 * load.c (scm_primitive_load_path): Do not check for absolute
4191 filenames when scm_sys_search_load_path returns false, which will
4192 return absolute filenames unchanged.
4194 2004-08-11 Marius Vollmer <mvo@zagadka.de>
4196 * gc.c, procprop.c (scm_init_storage, scm_stand_in_procs,
4197 scm_stand_in_proc): Use a hastable for scm_stand_in_procs instead
4198 of an alist. Thanks to Matthias Koeppe!
4200 2004-08-10 Marius Vollmer <marius.vollmer@uni-dortmund.de>
4202 * strings.h, deprecated.h (SCM_STRING_COERCE_0TERMINATION_X):
4203 Moved from string.h to deprecated.h.
4205 * deprecated.c, deprecated.h (SCM_CHARS, SCM_LENGTH): Removed.
4207 * strings.h, strings.c (SCM_MAKE_STRING_TAG): Renamed to
4208 SCM_I_MAKE_STRING_TAG, changed all uses.
4209 (SCM_STRING_CHARS, SCM_STRING_UCHARS, SCM_STRING_LENGTH): Renamed
4210 to SCM_I_STRING_CHARS, SCM_I_STRING_UCHARS, and SCM_I_LENGTH
4211 respectively. For a short time, the old names are still there as
4212 aliases. Not all uses have been changed yet, but the ones in
4214 (SCM_STRING_MAX_LEN): Do not hardcode to 24 bits, compute from
4216 (scm_is_string, scm_from_locale_string, scm_from_locale_stringn,
4217 scm_take_locale_string, scm_take_locale_stringn,
4218 scm_to_locale_string, scm_to_locale_stringn,
4219 scm_to_locale_stringbuf): New.
4220 (scm_c_string2str, scm_c_substring2str): Deprecated by moving to
4221 deprecated.[hc]. Implemented in terms of the new functions above.
4222 (scm_take_str, scm_take0str, scm_mem2string, scm_str2string,
4223 scm_makfrom0str): Reimplemented in terms of the new functions from
4224 above. They will be discouraged shortly.
4225 (scm_substring): Do not use scm_mem2string.
4226 (scm_i_allocate_string_pointers, scm_i_free_string_pointers): New,
4227 to replace similar code from posix.c, simpos.c, and dynl.c.
4228 (scm_string_append): Use memcpy instead of explicit loop. Do not
4229 use register keyword. Use plain 'char' instead of 'unsigned
4232 * strports.c (scm_mkstrport): Use SCM_I_STRING_UCHARS instead of
4233 SCM_STRING_UCHARS. Use SCM_I_STRINGP instead of SCM_STRINGP.
4235 * strop.c (scm_i_index): Replaced SCM_STRINGP, SCM_STRING_CHARS,
4236 and SCM_STRING_LENGTH with SCM_I_STRINGP, SCM_I_STRING_CHARS, and
4237 SCM_I_STRING_LENGTH, respectively. Pass string object directly,
4238 not as a pointer. Use scm_remember_upto_here_1 to protect it.
4240 * read.c (scm_input_error): Use a SCM value for 'fn', not a C
4241 string. This avoids a conversion round-trip.
4243 * gh_data.c: Replaced SCM_STRINGP, SCM_STRING_CHARS, and
4244 SCM_STRING_LENGTH with SCM_I_STRINGP, SCM_I_STRING_CHARS, and
4245 SCM_I_STRING_LENGTH, respectively.
4246 (gh_scm2newstr): Implement in terms of scm_to_locale_string.
4248 * environments.c: Instead calling scm_puts on the SCM_STRING_CHARS
4249 of a string, call scm_display on the string itself.
4251 * dynwind.c, dynwind.h (scm_frame_free): New.
4253 * stime.c, socket.c, simpos.c, procs.c, posix.c, ports.c,
4254 net_db.c, fports.c, filesys.c, eval.c, deprecation.c, dynl.c:
4255 Replaced uses of SCM_STRING_CHARS with proper uses of
4256 scm_to_locale_string. Replaced SCM_STRINGP with scm_is_string.
4257 Replaced scm_mem2string with scm_from_locale_string.
4259 * simpos.c, posix.c (allocate_string_pointers, environ_list_to_c):
4260 Removed, replaced all uses with scm_i_allocate_string_pointers.
4262 * load.h, load.c (scm_internal_parse_path): Removed.
4263 (scm_parse_path): Use scm_string_split to do the work.
4264 (scm_init_load_path): Use scm_parse_path instead of
4265 scm_internal_parse_path.
4266 (scm_search_path): Rewritten string handling part of the code in
4267 terms of scm_to_locale_stringbuf and so that it is thread safe.
4269 * error.c (scm_error_scm): Throw directly instead of calling
4270 scm_error, this avoids the back and forth conversion of SUBR and
4271 MESSAGE and also plugs a memory leak.
4272 (scm_error): Call scm_error_scm.
4274 * backtrace.c: Replaced SCM_STRINGP with scm_is_string.
4275 (display_header): Print FNAME when it is true, not
4276 merely when it is a string.
4278 * strings.h (SCM_SET_STRING_LENGTH, SCM_SET_STRING_CHARS): Removed
4279 unceremoniously. They were unused by Guile itself, and external
4280 use should stop immediately.
4283 2004-08-10 Marius Vollmer <mvo@zagadka.de>
4285 * numbers.h, number.c, deprecated.h, deprecated.c (scm_round,
4286 scm_truncate): Renamed to scm_c_round and scm_c_truncate;
4287 deprecated versions installed in deprecated.h and deprecated.c.
4290 2004-08-06 Rob Browning <rlb@defaultvalue.org>
4292 * net_db.c (scm_resolv_error): don't cause an exception while
4293 trying to throw an exception -- call scm_misc_error with correct
4294 arguments. The previous arguments needed a format escape that
4295 wasn't in any of the format strings.
4297 2004-08-06 Kevin Ryde <user42@zip.com.au>
4299 * ramap.c (scm_array_fill_x): For byvect char fill, force signed char
4300 so as not to depend on signedness of plain char. For byvect range
4301 check, throw out-of-range rather than wrong-type-arg.
4303 * unif.c (scm_uniform_vector_ref, scm_array_set_x): For byvect, force
4304 signed byte range checks by using scm_to_schar and scm_from_schar,
4305 don't want to depend on signedness of C char.
4307 2004-08-05 Kevin Ryde <user42@zip.com.au>
4309 * arbiters.c (scm_try_arbiter): Use scm_i_misc_mutex instead of
4311 (scm_release_arbiter): Use scm_i_misc_mutex so return value can be
4312 guaranteed if multiple threads compete to unlock.
4313 Update docstrings per doc/ref/api-scheduling.texi.
4315 * filesys.c (scm_copy_file): Use fstat on the input fd rather than
4316 stat on the filename, to be certain a file rename can't mean we get
4317 info on one filesystem object but open another. This fstat usage is
4318 similar to Emacs copy-file.
4320 * posix.c (scm_setgroups): Enhance docstring, per doc/ref/posix.texi.
4322 * simpos.c (scm_system_star): Change scm_from_long to scm_from_int on

4407 * filesys.c (scm_copy_file): Avoid fd leak when destination file
4410 * symbols.c (scm_gensym): Use scm_i_misc_mutex around gensym_counter
4411 update, for thread safety.

4455 (scm_to_signed_integer, scm_to_unsigned_integer,
4456 scm_from_signed_integer, scm_from_unsigned_integer): Generate via
4457 conv-integer.i.c and conv-uinteger.i.c, as well.
4459 * number.h (scm_to_ssize_t, scm_to_size_t): Use the new
4460 SCM_I_SSIZE_MIN, SCM_I_SSIZE_MAX, and SCM_I_SIZE_MAX macros for
4461 the limits. Those are always defined.
4463 2004-07-29 Kevin Ryde <user42@zip.com.au>
4465 * posix.c (scm_ttyname): Use scm_i_misc_mutex for thread safety.
4467 2004-07-28 Kevin Ryde <user42@zip.com.au>
4469 * posix.c (scm_ctermid): Use an L_ctermid buf on the stack, for thread
4472 * unif.c (scm_array_set_x): For svect, use scm_num2short for
4473 consistency with other vector types and to get arg and func name into

4478 * deprecated.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOLP, SCM_BOOL):
4479 Reimplement using scm_is_false, scm_is_true, scm_is_bool, and
4480 scm_from_bool, respectively.
4481 (SCM_NINUMP): Added.
4483 * tags.h, deprecated.h (SCM_EQ_P): Deprecated by moving it into
4484 deprecated.h. Replaced all uses with scm_is_eq.
4486 2004-07-24 Kevin Ryde <user42@zip.com.au>
4488 * threads.c, threads.h (scm_i_misc_mutex): New SCM_GLOBAL_MUTEX.

4493 * deprecated.h, deprecated.c, numbers.h (SCM_INUMP, SCM_NINUMP,
4494 SCM_INUM): Deprecated by renaming them to SCM_I_INUMP,
4495 SCM_I_NINUMP and SCM_I_INUM, respectively and adding deprecated
4496 versions to deprecated.h and deprecated.c. Changed all uses to
4497 either use the SCM_I_ variants or scm_is_*, scm_to_*, or
4498 scm_from_*, as appropriate.
4500 * dynwind.c (scm_i_dowinds): Removed unused code that would call
4501 the unexisting scm_cross_dynwind_binding_scope for inums on the
4504 2004-07-10 Marius Vollmer <marius.vollmer@uni-dortmund.de>
4506 * socket.c (ipv6_net_to_num, scm_from_ipv6): Renamed
4507 ipv6_net_to_num to scm_from_ipv6, for converting from an IPv6
4508 byte-wise address to a SCM integer. Changed all uses.
4509 (ipv6_num_to_net, scm_to_ipv6): Renamed ipv6_num_to_net to
4510 scm_to_ipv6 and added type and range checking, for converting from
4511 an IPv& byte-wise address to a SCM integer. Changed all uses.
4512 (bignum_in_ipv6_range_p, VALIDATE_INET6): Removed, their function
4513 is now done by scm_to_ipv6.
4515 * numbers.c (scm_to_signed_integer, scm_to_unsigned_integer): dot
4516 not accept inexact integers.
4518 * validate.h, deprecated.h (SCM_VALIDATE_INUM,
4519 SCM_VALIDATE_INUM_COPY, SCM_VALIDATE_BIGINT,
4520 SCM_VALIDATE_INUM_MIN, SCM_VALIDATE_INUM_MIN_COPY,
4521 SCM_VALIDATE_INUM_MIN_DEF_COPY,SCM_VALIDATE_INUM_DEF,
4522 SCM_VALIDATE_INUM_DEF_COPY, SCM_VALIDATE_INUM_RANGE,
4523 SCM_VALIDATE_INUM_RANGE_COPY): Deprecated because they make the
4524 fixnum/bignum distinction visible. Changed all uses to
4525 scm_to_size_t or similar.
4527 2004-07-09 Marius Vollmer <marius.vollmer@uni-dortmund.de>
4529 * cpp_cnvt.awk: Use scm_from_int instead of SCM_MAKINUM.
4531 2004-07-10 Kevin Ryde <user42@zip.com.au>
4533 * hash.c (scm_hashq, scm_hashv, scm_hash): Restrict to size>=1 rather
4534 than size>=0, since 0<=hash<size cannot be satisfied for size==0, and
4535 such a size causes divide-by-zeros in scm_hasher.
4537 * regex-posix.c (scm_make_regexp): Free rx on error, to avoid memory
4540 2004-07-08 Marius Vollmer <marius.vollmer@uni-dortmund.de>
4542 * numbers.c (scm_is_signed_integer, scm_is_unsigned_integer):
4543 Rewritten using the same logic as scm_to_signed_integer and
4544 scm_to_unsigned_integer, respectively, which is better(tm). Also,
4545 use CHAR_BIT instead of hardcoding 8.
4546 (LLONG_MIN, LLONG_MAX, ULLONG_MAX): Removed and used
4547 SCM_I_LLONG_MIN etc. instead.
4549 * numbers.h (SCM_MAKINUM, SCM_I_MAKINUM): Renamed SCM_MAKINUM to
4550 SCM_I_MAKINUM and changed all uses.
4551 * deprecated.h, deprecated.c (SCM_MAKINUM): Newly deprecated.
4553 * gen-scmconfig.c (SCM_I_LLONG_MIN, SCM_I_LLONG_MAX,
4554 SCM_I_ULLONG_MAX): Instead of hard-coding the numbers, compute
4555 them by assuming twos-complement.
4557 2004-07-07 Marius Vollmer <marius.vollmer@uni-dortmund.de>
4559 * gen-scmconfig.h.in: Added all the new SCM_I_GSC_*_LIMITS that
4560 configure now produces.
4561 * gen-scmconfig.c: Use them to output SCM_T_INT8_MIN, etc
4562 definitions, giving the limits of the integer types defined by
4563 Guile. Also, output a hard coded SCM_I_LLONG_MIN, etc since
4564 LLONG_MIN or LONG_LONG_MIN is hard to get at.
4566 * numbers.h (scm_to_short, scm_to_ushort): It's SHRT_MIN, etc, not
4568 (scm_to_size_t): Use SIZE_MAX instead of cooking our own.
4569 (scm_to_long_long, scm_to_ulong_long, scm_to_int8, scm_to_uint8,

4575 scm_from_uintmax): New.
4577 2004-07-06 Marius Vollmer <marius.vollmer@uni-dortmund.de>
4579 * tags.h (scm_is_eq): New.
4581 * deprecated.h, boolean.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOL,
4582 SCM_NEGATE_BOOL, SCM_BOOLP): Deprecated by moving into
4583 "deprecated.h". Replaced all uses with scm_is_false, scm_is_true,
4584 scm_from_bool, and scm_is_bool, respectively.
4586 * boolean.h (scm_is_bool): Fix bug in prototype.
4587 (scm_from_bool): The argument is "x" not "f", stupid.
4589 * boolean.c (scm_is_bool): Fix typo.
4591 * numbers.h, numbers.c (scm_is_integer, scm_is_signed_integer,
4592 scm_is_unsigned_integer, scm_to_signed_integer,

4606 2004-06-27 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4608 * backtrace.c (display_expression, display_frame): Call
4609 scm_i_unmemoize_expr for unmemoizing a memoized object holding a
4610 single memoized expression.
4612 * debug.c (memoized_print): Don't try to unmemoize the memoized
4613 object, since we can't know whether it holds a single expression
4616 (scm_mem_to_proc): Removed check for lambda expression, since it
4617 was moot anyway. Whoever uses these functions for debugging
4618 purposes should know what they do: Creating invalid memoized code
4619 will cause crashes, independent of whether this check is present
4622 (scm_proc_to_mem): Take the closure's code as it is and don't
4623 append a SCM_IM_LAMBDA isym. To allow easier debugging, the
4624 memoized code should not be modified.
4626 * debug.[ch] (scm_unmemoize, scm_i_unmemoize_expr): Removed
4627 scm_unmemoize from public use, but made scm_i_unmemoize_expr
4628 available as a guile internal function instead. However,
4629 scm_i_unmemoize_expr will only work on memoized objects that hold
4630 a single memoized expression. It won't work with bodies.
4632 * debug.c (scm_procedure_source), macros.c (macro_print), print.c
4633 (scm_iprin1): Call scm_i_unmemocopy_body for unmemoizing a body,
4634 i. e. a list of expressions.
4636 * eval.c (unmemoize_exprs): Drop internal body markers from the
4637 output during unmemoization.
4639 * eval.[ch] (scm_unmemocopy, scm_i_unmemocopy_expr,
4640 scm_i_unmemocopy_body): Removed scm_unmemocopy from public use,
4641 but made scm_i_unmemocopy_expr and scm_i_unmemocopy_body available
4642 as guile internal functions instead. scm_i_unmemoize_expr will
4643 only work on a single memoized expression, while
4644 scm_i_unmemocopy_body will only work on bodies.
4646 2004-06-21 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4648 * eval.c (unmemoize_exprs): Handle semi-memoized code.
4650 (scm_cons_source, scm_primitive_eval): Prefer higher level
4651 predicate SCM_FALSEP over SCM_IMP.
4653 2004-06-15 Rob Browning <rlb@defaultvalue.org>
4655 * script.c (scm_shell_usage): minor phrasing change.
4657 * gc_os_dep.c: update ifdefery for macosx.
4658 (scm_get_stack_base): separate result initialization from
4659 declaration to slience warnings with macosx and hp-ux using gcc
4660 3.3. Thanks to Andreas Vögele.
4662 2004-06-13 Han-Wen Nienhuys <hanwen@xs4all.nl>
4664 * eval.c (unmemoize_exprs): use SCM_CONSP for the loop condition.
4666 2004-06-06 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4668 * list.[ch] (scm_i_finite_list_copy): New internal function to
4669 copy lists that are known to be finite (though not necessarily
4672 * debug.c (scm_procedure_source): Don't have scm_unmemocopy treat
4673 a closure's argument list like an expression of a body.
4675 * eval.c (unmemoize_expression, unmemoize_exprs, unmemoize_and,
4676 unmemoize_begin, unmemoize_case, unmemoize_cond, unmemoize_delay,
4677 unmemoize_do, unmemoize_if, unmemoize_lambda, unmemoize_let,
4678 unmemoize_letrec, unmemoize_letstar, unmemoize_or,
4679 unmemoize_set_x, unmemoize_apply, unmemoize_atcall_cc,
4680 unmemoize_at_call_with_values, unmemoize_future, sym_atslot_ref,
4681 unmemoize_atslot_ref, sym_atslot_set_x, unmemoize_atslot_set_x,
4682 unmemoize_builtin_macro): New static functions and symbols.
4684 (scm_unmemocopy): Rewritten in terms of the above. scm_unmemocopy
4685 now has a slightly different meaning: The memoized form that is
4686 receives as its argument is now interpreted as a sequence of
4687 expressions from a body.
4689 (unmemocar, scm_unmemocar): Since the whole functionality of
4690 unmemocar and scm_unmemocar is not needed any more, scm_unmemocar
4691 has its old content back and is deprecated, while unmemocar has
4694 (SCM_BIT7): Removed.
4696 (CEVAL): For unmemoizing a single expression, call
4697 unmemoize_expression instead of scm_unmemocopy, which now expects
4698 a sequence of body expressions. Eliminated unnecessary empty
4699 environment frame when executing let* forms. Eliminated
4700 unmemoization step from evaluator.
4702 2004-06-02 Marius Vollmer <marius.vollmer@uni-dortmund.de>
4704 * eval.c (scm_macroexp, macroexp): Renamed scm_macroexp to
4705 macroexp and made static. Added new version of scm_macroexp that
4706 emits a deprecation warning and then calls macroexp.
4707 (scm_m_undefine): Issue deprecation warning.
4709 2004-05-30 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4711 * eval.c (lookup_global_symbol, literal_p, try_macro_lookup):
4712 Modified to make set! work on symbols that represent syntactic
4715 2004-05-26 Han-Wen Nienhuys <hanwen@xs4all.nl>
4717 * gc.h (SCM_CELL_OBJECT_LOC): use SCM_GC_CELL_OBJECT to prevent
4718 compound expression as lvalue errors.
4720 2004-05-24 Marius Vollmer <mvo@zagadka.de>
4722 * dynwind.c (winder_mark): Use SCM_PACK to correctly convert the
4723 WINDER_DATA to a SCM.
4725 2004-05-24 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4727 * goops.c (compute_getters_n_setters, create_standard_classes,
4728 scm_add_slot): Compute closures by calling scm_i_eval_x on a
4729 lambda expression rather than creating them with scm_closure.
4731 2004-05-22 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4733 * eval.c (s_macro_keyword, scm_m_set_x): Remove checking for
4734 misplaced syntactic keywords. This will not work unless guile's
4735 defmacro feature is deprecated.
4737 (scm_m_case): Fixed a bug that caused the list of labels to grow
4738 with every case form.
4740 2004-05-19 Kevin Ryde <user42@zip.com.au>
4742 * numbers.c (scm_round_number): For inum and big, just return x. For
4743 real, use scm_round for 2^54-1 etc problems covered there.
4745 * numbers.c (trunc): Remove #define to scm_truncate when the C library
4746 doesn't provide trunc. This was for when `truncate' was done as a
4747 scm_tc7_dsubr, no longer required.
4749 * threads.c (scm_threads_mark_stacks) [SCM_STACK_GROWS_UP]: Correction
4750 to stack marking call, two parameters and no cast on t->base.
4752 2004-05-18 Marius Vollmer <mvo@zagadka.de>
4754 * hashtab.c (rehash_after_gc): Bug fix: properly link the
4755 processed hashtables back into the weak_hashtables list. Thanks
4756 to Bill Schottstaedt!
4758 2004-05-16 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4760 * eval.c (unmemoize_quote): New static function.
4762 (scm_m_quote, scm_m_atslot_ref, SCM_CEVAL): Changed the byte code
4763 representation of 'quote' and '@slot-ref' to an improper list.
4764 This reduces execution time, the number of cells used to hold the
4765 memoized code, and thus also reduces garbage collection time.
4767 (scm_unmemocopy): Use unmemoize_quote for quote expressions.
4769 (SCM_CEVAL): Changed macro handling to also work with macros that
4770 return improper lists. Added an assertion, that the code returned
4771 by a macro transformer will not lead to cycles in the memoized
4774 2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4776 No functional change, just rearrangements of functions within the
4779 * eval.c (scm_ilookup, scm_unbound_variable_key,
4780 error_unbound_variable, scm_lookupcar1, scm_lookupcar): Moved to
4781 the definitions used for execution, since that's where they will
4784 2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4786 * numbers.h (SCM_SLOPPY_FRACTIONP): Removed. It was not used
4787 throughout guile, has not been part of an official release yet,
4788 and the concept of sloppy predicates has never been a good idea.
4790 (SCM_FRACTION_NUMERATOR, SCM_FRACTION_DENOMINATOR,
4791 SCM_FRACTION_SET_NUMERATOR, SCM_FRACTION_SET_DENOMINATOR):
4794 2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4796 * throw.c (SETJBJMPBUF, SCM_SETJBDFRAME): Add cast to scm_t_bits
4797 to make explicit what happens.
4799 2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4801 * dynl.c (SET_DYNL_HANDLE): Add cast to scm_t_bits to make
4802 explicit what happens.
4804 * guardians.c (TCONC_IN): Use SCM_SET_CELL_OBJECT_x rather than
4805 SCM_SET_CELL_WORD_x when writing scheme objets to cell elements.
4807 2004-05-11 Marius Vollmer <mvo@zagadka.de>
4809 * scmsigs.c (scm_sigaction_for_thread): Validate that the handler
4810 is indeed a procedure when it isn't a number.
4812 2004-05-10 Marius Vollmer <mvo@zagadka.de>
4814 Convert floating point numbers into strings with an arbitrary
4815 radix. Thanks to Richard Todd!
4817 * numbers.c (FLOBUFLEN): Increase so that radix 2 strings will
4820 (scm_dblprec, fx_per_radix, init_dblprec, init_fx_radix,
4821 number_chars): New, to support variable radices.
4822 (idbl2str): Use above instead of the old base-10 only tables.
4823 (iflo2str): Pass on new RADIX argument to idbl2str.
4824 (scm_number_to_string): Pass radix to iflo2str.
4825 (scm_print_real, scm_print_complex): Explicitly pass radix 10 to
4827 (scm_init_numbers): Call init_dblprec and init_fx_radix for all
4830 2004-05-10 Kevin Ryde <user42@zip.com.au>
4832 * numbers.c (scm_logbit_p): Correction to test above the end of an
4833 inum. Reported by Jan Konecny.
4835 2004-05-06 Marius Vollmer <marius.vollmer@uni-dortmund.de>
4837 * gc.h (scm_t_cell): Fields are now of type SCM instead of
4838 scm_t_bits. Updated all users.
4839 (SCM_GC_CARD_SIZE_MASK): Use SCM_GC_SIZEOF_CARD instead of
4840 duplicating the code.
4841 (SCM_CELL_OBJECT_LOC): New.
4842 (SCM_CARLOC, SCM_CDRLOC): Use it instead of SCM_CELL_WORD_LOC.
4843 (SCM_CELL_WORD_LOC): Moved to "deprecated.h".
4845 * smob.h (SCM_SMOB_DATA_2, SCM_SMOB_DATA_3, SCM_SMOB_FLAGS,
4846 SCM_SET_SMOB_DATA_2, SCM_SET_SMOB_DATA_3, SCM_SET_SMOB_FLAGS,
4847 SCM_SMOB_OBJECT, SCM_SMOB_OBJECT_2, SCM_SMOB_OBJECT_3,
4848 SCM_SET_SMOB_OBJECT, SCM_SET_SMOB_OBJECT_2, SCM_SET_SMOB_OBJECT_3,
4849 SCM_SMOB_OBJECT_LOC, SCM_SMOB_OBJECT_2_LOC,
4850 SCM_SMOB_OBJECT_3_LOC): New.
4851 * smob.c (scm_i_set_smob_flags): New function.
4853 * dynl.c, dynwind.c, eval.h, fluids.h, futures.h, hashtab.h,
4854 hooks.h, keywords.h, macros.h, macros.c, mallocs.c, mallocs.h,
4855 random.h, regex-posix.h, root.h, srcprop.h, srcprop.c, threads.h:
4856 Use SCM_SMOB_* instead of SCM_CELL_* as appropriate. Use
4857 SCM_SMOB_FLAGS and SCM_SET_SMOB_FLAGS instead of accessing the
4858 zeroth word directly. Use SCM_SMOB_PREDICATE as appropriate.
4860 * numbers.h (SCM_I_BIG_MPZ): Use SCM_CELL_OBJECT_LOC instead of
4861 taking the address of SCM_CELL_WORD_1, the latter being no longer
4864 * variable.h (SCM_VARIABLE_LOC): Use SCM_CELL_OBJECT_LOC instead
4865 of casting SCM_CELL_WORD_LOC.
4867 2004-05-02 Kevin Ryde <user42@zip.com.au>
4869 * eval.c (scm_macroexp): Add prototype, since it's not in eval.h under
4870 --disable-deprecated. Reported by Andreas Vögele.
4872 * filesys.c (_POSIX_C_SOURCE): Define to 199506L to get readdir_r (in
4873 particular on HP-UX). Reported by Andreas Vögele.
4875 * list.c (varargs.h): Remove, leave just stdarg.h which is all the
4876 code has support for. Fixes building with AIX cc, which is ansi but
4877 doesn't define __STDC__. Reported by Keith Crane.
4878 (var_start): Remove macro, this variation no longer required.
4879 (scm_list_n): Use va_start directly.
4881 2004-05-01 Kevin Ryde <user42@zip.com.au>
4883 * continuations.c (scm_dynthrow): Use >= instead of SCM_PTR_GE which
4884 is now gone. Reported by Andreas Vögele.
4886 2004-04-28 Kevin Ryde <user42@zip.com.au>
4888 * backtrace.c (display_frame_expr), numbers.c (XDIGIT2UINT,
4889 mem2uinteger, mem2decimal_from_point, mem2ureal): Cast char to int for
4890 ctype.h tests, to avoid warnings from gcc on HP-UX about char as array
4891 subscript. Reported by Andreas Vögele.
4892 Also cast through unsigned char to avoid passing negatives to those
4893 macros if input contains 8-bit values.
4895 * num2integral.i.c (NUM2INTEGRAL): Under non-BIGMPZ_FITSP case,
4896 corrections to range check for signed numbers. Remove
4897 scm_remember_upto_here_1(num) from these checks, since num is used
4898 subsequently anyway.
4900 * num2integral.i.c (NUM2INTEGRAL): Test BIGMPZ_FITSP with "!= 0" to
4901 avoid warning from gcc 3.4. Reported by Hyperdivision.
4903 * numbers.c (scm_bit_extract): Use min instead of MIN.
4904 (MIN): Remove, this conflicts with similar macro defined by limits.h
4905 on HP-UX. Reported by Andreas Vögele.
4907 * stime.c (_POSIX_C_SOURCE): Define to 199506L to get gmtime_r (in
4908 particular on HP-UX). Reported by Andreas Vögele.
4910 * threads.c (scm_threads_mark_stacks): Correction sizet -> size_t.
4911 Reported by Andreas Vögele.
4913 * threads-plugin.h (SCM_MUTEX_MAXSIZE): Increase to 25*sizeof(long),
4914 for the benefit of hpux11 where pthread_mutex_t is 88 bytes. Reported
4917 2004-04-22 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4919 * eval.c (s_macro_keyword): New static identifier.
4921 (scm_m_define): Change order to first create binding and
4922 evaluating the expression afterwards.
4924 (scm_m_set_x): Memoize complete set! expression. Only leave
4925 symbols if no binding exists at memoization time. Throw error if
4926 assigning to a syntactic keyword.
4928 (lazy_memoize_variable): New function.
4930 (CEVAL): When execution set!, perform lazy memoization if
4931 unmemoized symbol is detected.
4933 * modules.c (module_variable): Return variables with unbound
4936 * tags.h: Fix comment.
4938 2004-04-25 Kevin Ryde <user42@zip.com.au>
4940 * chars.c (scm_char_upcase, scm_char_downcase, scm_c_upcase,
4941 scm_c_downcase): Use ctype.h toupper and tolower. This will be useful
4942 in 8-bit locales, and ensures consistency with char-upper-case? and
4943 char-lower-case? which already use ctype.h.
4944 (scm_c_upcase_table, scm_c_downcase_table, scm_lowers, scm_uppers):
4946 * chars.c, chars.h, init.c (scm_tables_prehistory): Remove.
4948 * socket.c (VALIDATE_INET6): Correction to bignum_in_ipv6_range_p
4949 call. Reported by Hyperdivision.
4951 * threads.c (scm_yield): Correction, actually call scm_thread_yield.
4952 Reported by Hyperdivision.
4954 * unif.c (s_scm_make_uve): Remove unused local variable. Reported by
4957 2004-04-22 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4959 Hide the implementation of ilocs and isyms in eval.c.
4961 * deprecated.h (SCM_IFRINC, SCM_ICDR, SCM_IFRAME, SCM_IDIST,
4962 SCM_ICDRP), eval.c (SCM_IFRINC, SCM_ICDR, SCM_IFRAME, SCM_IDIST,
4963 SCM_ICDRP), eval.h (SCM_ICDR, SCM_IFRINC, SCM_IFRAME, SCM_IDIST,
4964 SCM_ICDRP): Deprecated and added to deprecated.h. Moved from
4967 * deprecated.c (scm_isymnames), deprecated.h (scm_isymnames,
4968 SCM_ISYMNUM, SCM_ISYMCHARS), eval.c (SCM_ISYMNUM, isymnames,
4969 scm_unmemocopy, CEVAL), print.c (scm_isymnames), tags.h
4970 (SCM_ISYMNUM, scm_isymnames, SCM_ISYMCHARS): Deprecated
4971 scm_isymnames, SCM_ISYMNUM and SCM_ISYMCHARS and added to
4972 deprecated.[hc]. Moved scm_isymnames from print.c to eval.c and
4973 renamed to isymnames. Moved SCM_ISYMNUM from tags.h to eval.c and
4976 * eval.c (scm_i_print_iloc, scm_i_print_isym), eval.h
4977 (scm_i_print_iloc, scm_i_print_isym), print.c (scm_iprin1):
4978 Extracted printing of ilocs and isyms to guile internal functions
4979 scm_i_print_iloc, scm_i_print_isym of eval.c.
4981 2004-04-22 Kevin Ryde <user42@zip.com.au>
4983 * numbers.c (scm_bit_extract): Use SCM_SRS for signed right shift.
4985 * numbers.c (scm_round): Test for x already an integer, to avoid bad
4986 rounding in x+0.5 when x is a big value already an integer. In
4987 certain hardware rounding cases x+0.5 can give an adjacent integer,
4988 leading to that as the result, when we really just wanted x itself.
4990 2004-04-19 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
4992 * eval.c (scm_unmemocopy): Fixed unmemoization of let*.
4994 (deval_args, CEVAL): Minor improvements: Reduced variable scopes,
4995 added const qualifiers, cast intentionally unused expressions to
4996 void for emphasis, improved comment.
4998 2004-04-18 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
5000 * tags.h (scm_tags, scm_tc8_tags, scm_tc9_flag, scm_tc8_flag,
5001 scm_tc8_isym): Renamed scm_tags to scm_tc8_tags. Renamed
5002 scm_tc9_flag to scm_tc8_flag. Introduced new identifier
5003 scm_tc8_isym. Defined tc8-tags relative to scm_tc3_imm24.
5004 Defined the tc8-tag for flags to be 0x04, which will mean that
5005 SCM_BOOL_F will also have the value 0x04 instead of 0x013c. Due
5006 to the reduced number of bits and the simpler bit pattern for
5007 SCM_BOOL_F, certain machines may be able to use more efficient
5008 processor instructions to deal with SCM_BOOL_F.
5010 (SCM_ITAG9, SCM_MAKE_ITAG9, SCM_ITAG9_DATA): Removed. These have
5011 never been defined in a released version, thus no need to
5014 (SCM_IFLAGP, SCM_MAKIFLAG, SCM_IFLAGNUM): Flags now use tc8
5015 instead of tc9 tags.
5017 (SCM_ISYMP, SCM_MAKISYM, SCM_ISYMNUM): Isyms now use tc8 instead
5020 (SCM_MAKSPCSYM): Removed. It is almost impossible that user code
5021 could have used this definition.
5023 (SCM_IM_AND, SCM_IM_BEGIN, SCM_IM_CASE, SCM_IM_COND, SCM_IM_DO,
5024 SCM_IM_IF, SCM_IM_LAMBDA, SCM_IM_LET, SCM_IM_LETSTAR,
5025 SCM_IM_LETREC, SCM_IM_OR, SCM_IM_QUOTE, SCM_IM_SET_X): Now encoded
5026 as isyms, as special isyms don't exist any more.
5028 2004-04-18 Kevin Ryde <user42@zip.com.au>
5030 * filesys.c (scm_readdir): Use readdir_r when available, for thread
5033 * numbers.c (scm_max, scm_min): For big/real, use SCM_SWAP rather than
5034 explicit swapping code.
5036 2004-04-15 Kevin Ryde <user42@zip.com.au>
5038 * cpp_sig_symbols.in: Add SIGSYS.
5040 * list.c (scm_append_x): Use iterative style, to avoid non-tail
5043 * numbers.c (scm_max, scm_min): For inum/frac, frac/inum, big/frac,
5044 frac/big and frac/frac, use scm_less_p for exact comparison.
5046 * numbers.c (scm_gcd): For inum/big, use mpz_gcd_ui by sharing code
5049 * numbers.c (xisinf): Add a comment about solaris 7 lacking isinf.
5051 2004-04-06 Han-Wen Nienhuys <hanwen@xs4all.nl>
5053 * inline.h (scm_cell): use SCM_GC_CELL_WORD for checking tag.
5055 * chars.h (scm_init_chars): change scm_{upcase,downcase} to
5056 scm_c_{up,down}case.
5057 (SCM_MAKE_CHAR): add (unsigned char) cast. This prevents havoc
5058 when hi-bit ASCII is subjected to SCM_MAKE_CHAR().
5060 2004-04-06 Kevin Ryde <user42@zip.com.au>
5062 * numbers.c (scm_ash): Remove stray "}" in docstring.
5064 * numbers.c (scm_make_ratio): For inum/bignum integer detection, use
5065 x==SCM_MOST_NEGATIVE_FIXNUM explicitly, for clarity and to avoid
5066 calling mpz_cmp_ui in most cases.
5068 * numbers.c (scm_quotient, scm_remainder): In inum/big, use mpz_cmp_ui
5069 for big == abs(most-negative-fixnum) special case.
5070 (abs_most_negative_fixnum): Remove, no longer used.
5072 * scmsigs.c (scm_sigaction_for_thread): Correction to signum range
5073 test, avoids SCM_VECTOR_REF outside bounds of signal_handlers on
5074 calling (sigaction NSIG).
5076 * simpos.c (scm_system_star): Fix execargv memory leak, merge parent
5077 and fork error cases to do this.
5079 2004-04-03 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
5081 * eval.c (CEVAL): Don't distinguish between short and long
5082 instructions when dispatching - just always dispatch on the
5083 instruction code, which is common for short and long instructions.
5084 Further, removed unnecessary goto statements and added comment.
5086 2004-04-03 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
5088 * eval.c (scm_unmemocopy): Don't distinguish between short and
5089 long instructions when dispatching - just always dispatch on the
5090 instruction code, which is common for short and long instructions.
5091 Further, removed unnecessary goto statements, fixed indentation
5092 and replaced SCM_IMP predicates by SCM_NULLP.
5094 2004-04-03 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
5096 * eval.c (scm_lookupcar1, CEVAL): Use SCM_ILOCP instead of
5097 comparison with SCM_ILOC00. In CEVAL, eliminate goto-label
5100 2004-03-31 Kevin Ryde <user42@zip.com.au>
5102 * simpos.c: Include <signal.h> for SIG_IGN and friends.
5104 2004-03-29 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
5106 Introduce scm_debug_mode_p as a replacement for scm_debug_mode and
5109 * debug.h (scm_debug_mode_p, scm_debug_mode, SCM_DEBUGGINGP),
5110 eval.c (scm_debug_mode_p): Deprecated scm_debug_mode and
5111 SCM_DEBUGGINGP. Provided scm_debug_mode_p instead, to have one
5112 single interface that also matches the naming conventions.
5113 Probably scm_debug_mode_p should be part of the private interface
5116 * debug.h (scm_debug_mode_p), backtrace.c (display_error_body),
5117 eval.c (SCM_APPLY, scm_trampoline_0, scm_trampoline_1,
5118 scm_trampoline_2): Change uses of scm_debug_mode or SCM_DEBUGGINGP
5119 to scm_debug_mode_p.
5122 Deprecate direct access to scm_ceval, scm_deval and scm_ceval_ptr:
5124 * eval.h (scm_ceval, scm_deval, scm_ceval_ptr), debug.h
5125 (scm_ceval_ptr): Deprecated. Moved declaration of scm_ceval_ptr
5126 from debug.h to eval.h.
5128 * debug.h (SCM_RESET_DEBUG_MODE): Don't access scm_ceval_ptr any
5129 more, just leave it with setting scm_debug_mode_p, which is
5130 equivalent for practical purposes.
5132 * deprecated.h (SCM_XEVAL, SCM_XEVALCAR): Call scm_i_eval_x
5133 instead of *scm_ceval_ptr. Leave all evaluating to scm_i_eval_x.
5135 * gdbint.c (gdb_eval): Call scm_i_eval_x instead of scm_ceval.
5137 * eval.c (ceval, deval, scm_ceval, scm_deval): Made scm_ceval
5138 static and renamed it to ceval throughout. Provide a new exported
5139 but deprecated function scm_ceval as a wrapper for backwards
5140 compatibility. The same is done for the deval/scm_deval pair of
5143 * eval.c (CEVAL, SCM_CEVAL): Renamed SCM_CEVAL to CEVAL
5144 throughout. Defined CEVAL to ceval or deval, based on compilation
5147 * eval.c (SCM_XEVAL, SCM_XEVALCAR): Dispatch on scm_debug_mode_p
5148 to ceval and deval instead of calling *scm_ceval_ptr.
5150 * eval.c (dispatching_eval): New deprecated static function.
5152 * eval.c (scm_ceval_ptr): Initialized to dispatching_eval in order
5153 to emulate its old behaviour as closely as possible.
5156 Change the evaluator such that only expressions for which pair? is
5157 true are passed to CEVAL, and such that all other expressions are
5158 evaluated outside of CEVAL:
5160 * eval.c (EVAL): New, provided in analogy to EVALCAR. Evaluate an
5161 expression that is assumed to be memoized already. All but
5162 expressions of the form '(<form> <form> ...)' are evaluated inline
5163 without calling an evaluator.
5165 * eval.c (SCM_XEVAL, SCM_XEVALCAR, EVALCAR): Evaluate all but
5166 expressions of the form '(<form> <form> ...)' inline without
5167 calling an evaluator.
5169 * eval.c (scm_i_eval_x, scm_i_eval, scm_ceval, scm_deval): Handle
5170 the special case of unmemoized symbols passed on the top level.
5172 * eval.c (CEVAL): Change calls to CEVAL to EVAL, except where it
5173 is known that the expression passed to CEVAL is of the form
5174 '(<form> <form> ...)'. Remove handling of the tc7-objects, since
5175 now it is known that the input expression of CEVAL is a pair.
5177 2004-03-29 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
5179 * eval.c (is_self_quoting_p): New static function.
5181 (scm_m_quote): Use is_self_quoting_p.
5183 (copy_tree): Corrected typo in comment.
5185 2004-03-28 Han-Wen Nienhuys <hanwen@xs4all.nl>
5187 * eval.c (s_scm_copy_tree): idem.
5189 * list.c (s_scm_filter): remove "pointer" from doc string.
5191 * gc.h (SCM_GC_CELL_TYPE): SCM_GC_CELL_TYPE uses SCM_GC_CELL_OBJECT.
5193 * goops.h (SCM_NUMBER_OF_SLOTS): don't SCM_UNPACK the result.
5195 * backtrace.c ("display_backtrace_body"): SCM_PACK before SCM_EQ_P
5196 (display_frame): idem.
5197 (display_backtrace_file_and_line): idem.
5199 * tags.h (SCM_UNPACK): stricter typechecking on SCM_UNPACK
5202 2004-03-26 Kevin Ryde <user42@zip.com.au>
5204 * filesys.c (scm_getcwd, scm_readlink): Avoid memory leak on errors.
5206 * numbers.c (scm_modulo): For inum/big and big/big, remove test of
5207 big==0 since that never occurs.
5209 * numbers.c, numbers.h (scm_modulo_expt): Renamed from
5210 scm_modular_expt, matching scheme level name `modulo-expt'.
5212 * numbers.c (scm_modular_expt): Return a negative remainder for a
5213 negative divisor, the same as `modulo' does.
5215 2004-03-26 Eric Hanchrow <offby1@blarg.net>
5217 * numbers.c, numbers.h (scm_modular_expt): New function.
5219 2004-03-25 Kevin Ryde <user42@zip.com.au>
5221 * numbers.c (scm_min, scm_max): Correction to big/real and real/big,
5222 return inexact as required by r5rs.
5224 2004-03-24 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
5226 * eval.c: Separated some definitions relevant for execution from
5227 the memoization part of the file.
5229 (copy_tree): New static function
5231 (scm_copy_tree): Rewritten to fix two kinds or bugs: First, cyclic
5232 structures are detected now and will lead to an exception instead
5233 of forcing guile to run in an endless loop, using up all the
5234 system's memory. Second, arrays in the cdr of an improper list
5235 are now copied. See the new test cases in eval.test.
5237 2004-03-24 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
5239 * posix.c (scm_gethostname): Make sure len is initialised before
5240 it is used. Restructured to (hopefully) represent possible
5241 configurations more clearly in the code. Added unwind handler.
5243 2004-03-23 Kevin Ryde <user42@zip.com.au>
5245 * posix.c (scm_gethostname): Use sysconf(_SC_HOST_NAME_MAX) and/or
5246 MAXHOSTNAMELEN when available.
5248 2004-03-21 Marius Vollmer <mvo@zagadka.de>
5250 * read.c (skip_scsh_block_comment): Also recognize '\r' as a line
5251 terminator. Rewritten the logic as a state machine, I must have
5252 been doing too much VHDL lately...
5254 * eval.c (scm_ceval, scm_deval): Explicitely evaluate ports to
5255 themselves. Thanks to Han-Wen Nienhuys!
5257 * list.c: Changed docstrings so that they no longer talk about
5258 returning 'pointers' to something.
5260 2004-03-20 Han-Wen Nienhuys <hanwen@xs4all.nl>
5262 * gc.c: remove set_debug_cell_accesses! when
5263 SCM_DEBUG_CELL_ACCESSES is not defined. Scheme source code should
5264 use (if (defined? 'set-debug-cell-accesses!) .. ) to switch on
5265 debugging conditionally.
5267 2004-03-21 Kevin Ryde <user42@zip.com.au>
5269 * stime.c (scm_gmtime): Use gmtime_r when available, for thread safety.
5271 2004-03-20 Kevin Ryde <user42@zip.com.au>
5273 * posix.c (scm_gethostname): Preserve errno across free() call.
5275 2004-03-18 Han-Wen Nienhuys <hanwen@xs4all.nl>

5280 2004-03-14 Kevin Ryde <user42@zip.com.au>
5282 * stime.c: Define _GNU_SOURCE for strptime prototype from glibc.
5283 (strptime): Use HAVE_DECL_STRPTIME for when to give own prototype.
5285 2004-03-07 Kevin Ryde <user42@zip.com.au>
5287 * stime.c (scm_gmtime): Return bd_time->tm_zone when available, rather
5289 (filltime): Make zname parameter "const".
5291 2004-03-03 Mikael Djurfeldt <mdj@chunk.mit.edu>
5293 * threads.c, threads.h (scm_c_scm2thread): New function.
5295 2004-02-29 Kevin Ryde <user42@zip.com.au>
5297 * numbers.c (guile_ieee_init): Use C99 INFINITY and NAN when
5298 available. Test HAVE_DINFINITY and HAVE_DQNAN for those globals, in
5299 particular don't assume "defined (__alpha__) && ! defined (linux)"
5300 means OSF. Remove "SCO" code, which was not really SCO specific and
5301 which John W. Eaton advises should be long past being needed.
5303 * posix.c (scm_execl, scm_execlp, scm_execle): Avoid memory leak under
5306 2004-02-24 Kevin Ryde <user42@zip.com.au>
5308 * posix.c (scm_cuserid): Use a private result buffer, for thread safe.
5310 2004-02-22 Kevin Ryde <user42@zip.com.au>
5312 * numbers.c (scm_max, scm_min): For one arg, dispatch to generic for
5313 complex, same as for two args. (Handle only inum, big, real, frac).
5315 2004-02-21 Kevin Ryde <user42@zip.com.au>
5317 * posix.c (scm_crypt): Use new HAVE_CRYPT.
5318 (<crypt.h>): Remove HAVE_LIBCRYPT condition.
5319 Reported by Andreas Voegele.
5321 2004-02-20 Neil Jerram <neil@ossau.uklinux.net>
5323 * list.c (scm_list_n): Add #if SCM_DEBUG_CELL_ACCESSES_P around

5340 "net_db.h". Thanks to Bill Schottstaedt!
5342 2004-02-18 Kevin Ryde <user42@zip.com.au>
5344 * num2integral.i.c (INTEGRAL2BIG): WORDS_BIGENDIAN not right for word
5345 order parameter to mpz_import, in fact with just one word there's no
5346 order to worry about at all.
5348 * numbers.c (scm_num_eq_p): For real==frac, complex==frac, frac==real
5349 and frac==complex, make an exact comparison rather than converting
5350 with fraction2double.
5352 * posix.c, putenv.c, stime.c (environ): Use _NSGetEnviron in Darwin
5353 shared library, since environ is not directly available there.
5355 * script.c (scm_shell_usage): Print to stdout for --help, per GNU
5358 * stime.c (scm_localtime, scm_gmtime, scm_mktime): Provide a default
5359 errno EINVAL in case localtime and gmtime don't set it.
5360 (scm_mktime, scm_strptime): Forcibly use errno EINVAL for our
5361 SCM_SYSERROR, since mktime and strptime generally don't set errno.
5363 2004-02-16 Kevin Ryde <kevin@swox.se>
5365 * gc-malloc.c (scm_done_malloc, scm_done_free): Allow negative sizes,
5366 which were permitted in the past for these.

5376 * unif.c (scm_make_uve): Removed local variable and simplified
5377 code in order to avoid compiler used uninitialized warnings.
5379 * hashtab.c, hashtab.h (scm_hash_map_to_list): Renamed from
5381 (scm_hash_fold): Use scm_call_3 directly in the call to
5382 scm_internal_hash_fold instead of going via fold_proc (which is
5384 (scm_hash_for_each): Use a trampoline +
5385 scm_internal_hash_for_each_handle.
5386 (scm_internal_hash_for_each_handle, scm_hash_for_each_handle): New
5389 2004-02-12 Kevin Ryde <user42@zip.com.au>

5392 (scm_set_port_line_x): In docstring, note first line is 0.
5393 (scm_port_column): In docstring, there's no default to current input
5394 port, and remove shared port-line @defun.
5395 (scm_set_port_column_x): In docstring, there's no default to current
5396 input port, note first column is 0, remove shared set-port-line!
5399 * ramap.c (scm_array_fill_x): For fvect and dvect, use scm_num2dbl to
5400 convert args the same way that array-set! does.
5402 * unif.c (scm_make_uve, scm_array_p): Allow fraction 1/3 as prototype
5404 (scm_array_p): Add missing "break"s in switch, fix llvect test look
5405 for "l" not "s", fix dvect to be false for singp(prot) since such a

5418 * read.c (scm_read_opts): New opts `elisp-vectors' and
5421 (scm_lreadr): Use scm_lreadparen1 instead of scm_lreadparen. Make
5422 handling of elisp vector syntax dependent on SCM_ENABLE_ELISP and
5423 `elisp-vectors' option instead of SCM_ELISP_READ_EXTENSIONS.
5424 Allow "\(" and "\)" in strings when SCM_ENABLE_ELISP defined and
5425 `escaped-parens' option set.
5426 (scm_read_token): If elisp vector syntax active, disallow [ and ]
5428 (scm_lreadparen): Rewrite as interface to scm_lreadparen1.
5429 (scm_lreadparen1): New.
5431 * read.h: Remove conditionally compiled last arg to
5433 (SCM_ELISP_VECTORS_P, SCM_ESCAPED_PARENS_P): New.
5435 2004-01-23 Han-Wen Nienhuys <hanwen@xs4all.nl>
5437 * eval.c (m_expand_body): remove stray variable new_body.
5439 2004-01-22 Marius Vollmer <mvo@zagadka.de>
5441 * eval.c (m_expand_body): Rewrite the expression in place (by
5442 overwriting FORMS) also when a letrec is constructed, not only
5443 when no definitions are found. Do not return rewritten expression
5444 to emphasize the in-place rewriting. Changed all users.
5446 2004-01-19 Han-Wen Nienhuys <hanwen@xs4all.nl>
5448 * gc.c: add protected_object_count, a number that is dumped from
5451 2004-01-11 Marius Vollmer <mvo@zagadka.de>
5453 * dynwind.h, dynwind.c (scm_frame_unwind,
5454 scm_frame_unwind_handler): Renamed and changed all uses.

5461 changes made to scheme-compound.texi.
5463 2004-01-10 Marius Vollmer <mvo@zagadka.de>
5465 * print.c (scm_print_symbol_name): Handle #{`foo}#, #{,foo}#,
5466 #{.}#, and all numeric strings specially. Thanks to Paul Jarc!
5468 * guile-snarf.in: Use mkdir to create a unique temporary directory
5469 that we can safely use. Thanks to Stefan Nordhausen!
5471 2004-01-07 Marius Vollmer <marius.vollmer@uni-dortmund.de>
5473 * dynwind.h, dynwind.c (scm_i_dowinds): Removed 'explicit'
5474 argument since it is always zero now. Changed all callers.
5475 Removed code for handling fluids.
5477 * fluids.c (scm_c_with_fluids): Use frames instead of adding to
5478 the wind chain explicitely. Use scm_c_with_fluid for the common
5479 case of only one fluid.
5480 (scm_with_fluid): New.
5481 (scm_c_with_fluid): Use frames instead of scm_c_with_fluids.
5483 * fluids.h, fluids.c (scm_frame_fluid): New.
5484 (scm_with_fluid): New.
5485 (scm_i_swap_fluids, scm_i_swap_fluids_reverse): Removed.
5487 * dynwind.c (scm_frame_end): Do not use scm_i_dowinds. Instead,
5488 do the unwinding directly. It is simple enough.
5490 * dynwind.h, dynwind.c: Did the following renamings:
5491 scm_begin_frame -> scm_frame_begin,
5492 scm_end_frame -> scm_frame_end,
5493 scm_on_unwind -> scm_frame_unwind,
5494 scm_on_rewind -> scm_frame_rewind,
5495 scm_on_unwind_with_scm -> scm_frame_unwind_with_scm,
5496 scm_on_rewind_with_scm -> scm_frame_rewind_with_scm.
5499 * aync.h, async.c: Did the follwing renamings:
5500 scm_with_blocked_asyncs -> scm_frame_block_asyncs,
5501 scm_with_unblocked_asyncs -> scm_frame_unblock_asyncs.
5504 * ports.h, ports.c: Did the follwing renamings:
5505 scm_with_current_input_port -> scm_frame_current_input_port,
5506 scm_with_current_output_port -> scm_frame_current_output_port,
5507 scm_with_current_error_port -> scm_frame_current_error_port.
5510 2004-01-07 Kevin Ryde <user42@zip.com.au>
5512 * numbers.c (s_bignum): Remove, not used since gmp bignums.
5513 Reported by Richard Todd.
5515 * threads-plugin.h (SCM_MUTEX_MAXSIZE): Increase to 12*sizeof(long),
5516 for the benefit of powerpc-apple-darwin5.5. Reported by Richard Todd.
5518 * unif.c (scm_aind): Test SCM_CONSP rather than !SCM_NULLP while
5519 traversing the args list, fixes segv if an improper list is given.
5520 Reported by Rouben Rostamian.
5522 2004-01-06 Marius Vollmer <marius.vollmer@uni-dortmund.de>
5524 * ports.c (swap_ports, scm_with_current_foo_port): Do not allocate
5525 swap_data on stack, use a 'malloc obj'.
5527 * fluids.h, fluids.c (scm_make_initial_fluids, scm_copy_fluids,
5528 scm_swap_fluids, scm_swap_fluids_reverse): Renamed to
5529 scm_i_... since they are internal. Changed all uses.
5531 * dynwind.c (frame_print): Removed, use the default printer.
5532 (WINDER_F_MARK, WINDER_MARK_P, winder_mark): New.
5533 (scm_on_unwind_with_scm, scm_on_rewind_with_scm): New. Use above
5534 to protect SCM values.
5536 * dynwind.h (SCM_F_WIND_EXPLICITELY,
5537 SCM_F_WIND_EXPLICITLY): It's "explicitly" not "explicitely", damn.
5539 (scm_on_unwind_with_scm, scm_on_rewind_with_scm): New.
5541 2004-01-05 Marius Vollmer <mvo@zagadka.de>

5552 scm_begin_frame, scm_end_frame, scm_on_unwind, scm_on_rewind):
5554 (scm_dowinds, scm_i_dowinds): scm_dowinds has been renamed to
5555 scm_i_dowinds and extended to handle frames and to invoke a 'turn'
5556 function when the outermost wind point has been reached. The
5557 latter is used to copy a continuation stack at the right time.
5558 scm_dowinds remains available.
5559 (SCM_GUARDSP, SCM_BEFORE_GUARD, SCM_AFTER_GUARD, SCM_GUARD_DATA,
5560 tc16_guard, guards_print): Removed.
5561 (scm_internal_dynamic_wind): Reimplemented using frames.
5563 * continuations.c (copy_stack): New, do only the stack copying
5564 part of copy_stack_and_call.
5565 (copy_stack_and_call): Copy the stack after unwinding and before
5567 (scm_dynthrow): Do not call scm_dowinds, this is now done by
5568 copy_stack_and_call.
5570 2004-01-04 Kevin Ryde <user42@zip.com.au>
5572 * numbers.c (scm_less_p): Don't convert frac to float for compares,
5573 can give bad results due to rounding.
5575 * stime.c (scm_current_time, scm_gettimeofday): Add a comment about
5576 setzone/restorezone protection for DOS.
5578 2003-12-26 Marius Vollmer <mvo@zagadka.de>
5580 * gen-scmconfig.h.in, gen-scmconfig.c: Arrange for scm_t_intmax

5585 * numbers.c (scm_less_p): Remove spurious xisnan from frac+big case.
5587 * numbers.c (scm_make_ratio): Check for numerator equal to
5588 SCM_MOST_NEGATIVE_FIXNUM and bignum denominator the negative of that,
5591 * numbers.c (scm_real_part): Return fraction unchanged rather than
5592 converting to flonum.
5594 2003-11-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
5596 * modules.c (module_variable): Fixed (and thus simplified) the
5597 definition of SCM_BOUND_THING_P to reflect the fact that since
5598 after the 1.4 series of guile, obarrays only hold variable
5601 2003-11-30 Marius Vollmer <mvo@zagadka.de>
5603 * numbers.c (scm_logand): It's "#b...", not "#\b...".
5607 * read.c (scm_lreadr): Signal an error for invalid escape
5608 sequences in strings. Code cleanups too.
5610 * print.c (scm_iprin1): use \xNN hexadecimal sequences when
5611 writing control characters in strings.
5613 2003-11-21 Marius Vollmer <mvo@zagadka.de>
5615 * ports.c (scm_drain_input): Bug fix: only access the port after
5616 checking that it indeed is one.
5618 2003-11-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
5620 * eval.c (s_bad_define): New static identifier.
5622 (m_body): Fixed comment.
5624 (scm_m_define): Don't generate memoized code for definitions that
5625 are not on the top level. As a consequence, no memoized code at
5626 all is generated for definitions any more: Top level definitions
5627 are executed immediately during memoization and internal
5628 definitions are handled separately in m_expand_body.
5630 (scm_unmemocopy, unmemocopy): Removed code for unmemoizing
5631 definitions. Consequently, there is no unmemoizing code any more
5632 that might modify the environment. Thus, the old scm_unmemocopy
5633 is removed and the old unmemocopy is renamed to scm_unmemocopy.
5635 (SCM_CEVAL): The SCM_IM_DEFINE keyword can no longer occur in
5636 memoized code. Call EVALCAR for continuations. Prefer !SCM_NULLP
5637 over SCM_NIMP in places, where the argument is known to be part of
5640 2003-11-21 Kevin Ryde <user42@zip.com.au>
5642 * numbers.c (scm_abs): Allocate a new real only for negatives, as done
5645 * numbers.c (scm_bit_extract): Use mpz functions, rearrange inum case
5646 to share some shifting.
5648 * numbers.c (scm_integer_expt): Don't mpz_init after scm_i_clonebig or
5649 scm_i_mkbig, since they do so already. Don't mpz_clear a bignum SCM,
5652 2003-11-19 Marius Vollmer <mvo@zagadka.de>
5654 * numbers.c (scm_make_ratio): Rewritten to have a simpler
5655 structure. Previously, not all cases with a negative denominator
5658 * numbers.c (mem2decimal_from_point): use scm_divide instead of
5659 scm_divide2real when forming the fractional part. This allows
5660 "#e1.2" to yield 6/5.
5662 * numbers.c (scm_i_fraction_equalp): Do not treat the return value
5663 of scm_equal_p as a C boolean, use SCM_FALSEP. Previously, all
5664 fractions were equal to each other regardless of value. Ooops.
5666 * numbers.c (scm_rationalize): Return an inexact result when given
5669 * numbers.c (scm_exact_p, scm_inexact_p): Throw error for

5688 New exact functions that replace the inexact 'dsubr'
5690 (scm_numerator, scm_denominator): New.
5692 * numbers.h (SCM_NUMP): Recognize fractions.
5693 (SCM_FRACTIONP, SCM_SLOPPY_FRACTIONP, SCM_FRACTION_NUMERATOR,

5707 * gc-mark.c (scm_gc_mark_dependencies): Handle fractions.
5709 * gc-card.c (scm_i_sweep_card): Include scm_tc16_fraction as a
5710 case in the switch, but do nothing for now.
5712 * eval.c (SCM_CEVAL, SCM_APPLY, call_dsubr_1): Convert fractions
5713 to doubles when calling 'dsubr' functions.
5715 * eq.c (scm_eqv_p, scm_equal_p): Handle fractions.
5717 2003-11-18 Rob Browning <rlb@defaultvalue.org>
5719 * gen-scmconfig.c (main): remove public definition of
5720 SCM_SIZEOF___INT64 and SCM_SIZEOF_UNSIGNED___INT64 and add
5721 direct typedef of long_long and ulong_long inside deprecated block
5724 * deprecated.h: move long_long and ulong_long definitions to
5725 gen-scmconfig.c so that we don't need to add SCM_SIZEOF___INT64
5726 and SCM_SIZEOF_UNSIGNED___INT64 to the public namespace.
5728 2003-11-17 Marius Vollmer <mvo@zagadka.de>
5730 * hash.c (scm_string_hash): New hashing algorithm that takes the
5731 complete string into account.
5733 * eval.c (scm_m_generalized_set_x): Macroexpand the target when it
5734 is a list. This allows (@ ...) to work with set!.
5735 (scm_m_generalized_set_x): Use ASSERT_SYNTAX_2 instead of
5738 * script.c (scm_compile_shell_switches): Use scm_c_read_string for
5739 the "-e" option instead of scm_str2symbol. This allows things
5740 like (@ ...) to be specified for the entry point.
5742 2003-11-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
5744 * eval.c (scm_m_letstar): Create memoized code in place to
5747 2003-11-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
5749 * eval.c (s_splicing): Commented and reformulated.
5751 (lookup_global_symbol, lookup_symbol): New static functions.
5753 (s_test, s_bindings, s_duplicate_bindings, s_variable): Removed.
5755 (try_macro_lookup, literal_p): Use lookup_symbol instead of
5756 creating a temporary pair for scm_lookupcar.
5758 (scm_unmemocar, unmemocar): Renamed scm_unmemocar to unmemocar,
5759 created deprecated wrapper function scm_unmemocar.

6040 specific about the kind of error that was detected. Handle bound
6041 'else and '=>. Avoid unnecessary consing when creating the

6093 2003-10-02 Kevin Ryde <user42@zip.com.au>
6095 * strports.c (scm_call_with_output_string): scm_get_output_string
6096 rather than scm_strport_to_string, so as to guard against the port
6097 having been closed by the called procedure. Reported by Nic Ferrier.
6099 2003-09-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
6101 * numbers.h (SCM_INEXACTP): Removed uses of SCM_TYP16S.
6103 * tags.h, deprecated.h (SCM_TYP16S): Deprecated and moved from
6104 tags.h to deprecated.h.
6106 2003-09-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
6108 This set of patches introduces a new tc7 code scm_tc7_number for
6109 numbers. Bignums, reals and complex numbers are turned from smobs
6110 into subtypes of scm_tc7_number.
6112 * tags.h (scm_tc7_number): New.
6114 * eq.c (scm_equal_p), eval.c (SCM_CEVAL), evalext.c
6115 (scm_self_evaluating_p), gc-card.c (scm_i_sweep_card), gc-mark.c

6118 (scm_class_of), print.c (scm_iprin1), smob.c
6119 (scm_smob_prehistory): Don't handle bignums, reals and complex
6120 numbers as subtypes of scm_tc7_smob any more.
6122 * numbers.h, tags.h (scm_tc16_big, scm_tc16_real,
6123 scm_tc16_complex): Moved definitions from tags.h to numbers.h.
6125 2003-09-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
6127 * numbers.c (scm_make_complex), gc-card.c (scm_i_sweep_card): Use
6128 sizeof (scm_t_complex) to determine the memory size of the
6129 malloc'd area for complex numbers.
6131 2003-09-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
6133 * numbers.c (scm_bigequal): Fixed.
6135 2003-09-16 Marius Vollmer <mvo@zagadka.de>
6137 * stime.c (scm_current_time): 'time' does not set errno so don't
6138 use SCM_SYSERROR for reporting errors.
6140 2003-09-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
6142 This set of patches eliminates the dependency between the
6143 implementation of evaluator specific memoization codes and special
6144 constants like #f, '() etc. ('flags'), which are not evaluator
6145 specific. The goal is to remove definitions of evaluator
6146 memoization codes completely from the public interface. This will
6147 make it possible to experiment more freely with optimizations of
6148 guile's internal representation of memoized code.
6150 * objects.c (scm_class_of): Eliminate dependency on SCM_ISYMNUM.
6152 * print.c (iflagnames): New array, holding the printed names of
6153 guile's special constants ('flags').
6155 (scm_isymnames): Now holds only the printed names of the
6158 (scm_iprin1): Separate the handling of memoization codes and
6159 guile's special constants.
6161 * tags.h (scm_tc9_flag, SCM_ITAG9, SCM_MAKE_ITAG9, SCM_ITAG9_DATA,
6164 (scm_tc8_char, scm_tc8_iloc, SCM_BOOL_F, SCM_BOOL_T,
6165 SCM_UNDEFINED, SCM_EOF_VAL, SCM_EOL, SCM_UNSPECIFIED, SCM_UNBOUND,
6166 SCM_ELISP_NIL, SCM_IM_DISPATCH, SCM_IM_SLOT_REF,
6167 SCM_IM_SLOT_SET_X, SCM_IM_DELAY, SCM_IM_FUTURE,
6168 SCM_IM_CALL_WITH_VALUES, SCM_IM_NIL_COND, SCM_IM_BIND): Changed
6171 (SCM_IFLAGP): SCM_IFLAGP now only tests for flags.
6173 (SCM_IFLAGP, SCM_MAKIFLAG, SCM_IFLAGNUM): Generalized to use the
6174 tc9 macros and scm_tc9_flag.
6176 2003-09-15 Marius Vollmer <mvo@zagadka.de>
6178 * posix.c (scm_setgroups): Check that the gid list is not too
6179 long. Thanks to Paul Jarc!
6181 2003-09-14 Dirk Herrmann <D.Herrmann@tu-bs.de>
6183 * tags.h: Reduced the number of short instructions from 14 to 13.
6184 The typecode of the former 14th short instruction is now used to
6185 represent long instructions. Changed some comments to reflect
6188 (SCM_MAKISYM): ISYMs get a new tc7 code, namely the one that was
6189 previously used by SCM_IM_DEFINE.
6191 (SCM_IM_DEFINE): Turned into a long instruction.
6193 * eval.c (unmemocopy, SCM_CEVAL): Treat SCM_IM_DEFINE as a long
6196 * eval.c (SCM_CEVAL): Since characters and iflags have now a tc7
6197 code that is separate from all instructions, one level of dispatch
6198 for long instructions can be eliminated.
6200 * print.c (scm_isymnames): Removed some commented code.
6202 2003-09-12 Marius Vollmer <mvo@zagadka.de>
6204 * __scm.h (SCM_FENCE): Use __memory_barrier with the Intel
6207 * hashtab.h (scm_tc16_hashtable): Added "extern" declaration.
6209 * modules.c (scm_module_reverse_lookup): Check that the obarray
6210 really is a hashtable and do nothing if not.
6212 * inline.h: Use "extern inline" only with GCC. Use "static
6215 2003-09-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
6217 * numbers.h (SCM_INEXACTP, SCM_REALP, SCM_COMPLEXP): Removed uses
6218 of SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP.
6220 * numbers.h, deprecated.h (SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP,
6221 SCM_SLOPPY_COMPLEXP): Deprecated and moved from numbers.h to
6224 2003-09-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
6226 * eq.c (scm_eqv_p, scm_equal_p): Removed uses of
6227 SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP.
6229 * eq.c (scm_eqv_p, scm_equal_p): Reordered comparisons from
6230 0.0==some_expression to some_expression==0.0. The latter is
6231 better readable. The former is preferred by some people, since it
6232 leads to a compiler error when confusing == with =. However, when
6233 using gcc, a warning will be issued if in an if-statement an
6234 assigment appears. Since many Guile developers are using gcc,
6235 such errors will not remain unnoticed anyway. We can therefore
6236 focus on better readability.
6238 2003-09-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
6240 * tags.h: Added description of Guile's type system. Removed some
6241 old and misleading comments.
6243 2003-09-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
6245 * unit.c (scm_cvref): Eliminate unnecessary uses of SCM_NIMP,
6246 SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP.
6248 2003-09-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
6250 * numbers.h (SCM_MAKINUM): Define in terms of scm_tc2_int.
6252 (SCM_INEXACTP, SCM_REALP, SCM_COMPLEXP): Define in terms of the
6253 respective SLOPPY macro.
6255 2003-09-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
6257 * eq.c (scm_equal_p): Use SCM_TYP7 to check if an object is of
6258 type string, not SCM_TYP7S.
6260 2003-09-03 Kevin Ryde <user42@zip.com.au>
6262 * numbers.c (scm_lognot): Correction to docstring, ones-complement not
6265 * stime.c (scm_strptime): Add comment about glibc strptime %s and
6266 current timezone requiring SCM_DEFER_INTS.
6268 2003-08-30 Neil Jerram <neil@ossau.uklinux.net>
6270 * script.c (scm_compile_shell_switches): Make -s switch optional
6271 if file to be loaded does not begin with a `-'. (Thanks to Aaron
6272 VanDevender for the patch!)
6274 2003-08-30 Kevin Ryde <user42@zip.com.au>
6276 * numbers.c (scm_lognot): Rewrite using ~ and mpz_com, for directness
6277 and to have non-integer types rejected as per other logical funcs.
6279 2003-08-28 Kevin Ryde <user42@zip.com.au>
6281 * gc.h (scm_remember_upto_here_1): Revise comments on the asm form.
6283 2003-08-23 Kevin Ryde <user42@zip.com.au>
6285 * simpos.c (scm_system): Remove SCM_DEFER_INTS, system() should be
6286 thread safe, and could take a long time too.
6288 2003-08-22 Kevin Ryde <user42@zip.com.au>

6310 * properties.c (scm_primitive_property_ref): In docstring, note
6311 parameters to not-found-proc, use hyphens rather than underscores for
6312 that parameter name.
6313 (scm_primitive_property_set_x): In docstring, VAL is the value
6316 2003-07-27 Marius Vollmer <mvo@zagadka.de>

6332 compiles when SCM_C_INLINE is undefined.
6334 2003-07-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
6336 * __scm.h: Reformulated the architecture and compiler properties
6337 in terms of properties of scm_t_bits and SCM variables rather than
6338 in terms of c standard types. This is since it is not known which
6339 of the standard types scm_t_bits and SCM variables will be defined
6342 2003-07-24 Kevin Ryde <user42@zip.com.au>
6344 * numbers.c (scm_angle): Use scm_flo0 for non-negative inum, bignum
6347 2003-07-18 Kevin Ryde <user42@zip.com.au>
6349 * numbers.c (scm_product): In complex * bignum, correction to

6362 * values.c (scm_values): Build lists of length 1 by using
6363 scm_list_1 instead of using scm_cons.

6372 2003-07-08 Matthias Koeppe <mkoeppe@merkur.math.uni-magdeburg.de>
6374 * tags.h (scm_t_bits, scm_t_signed_bits, etc): Avoid solaris empty
6375 defines of INTPTR_MAX and UINTPTR_MAX, combine conditionals for
6376 scm_t_bits and scm_t_signed_bits to avoid any chance of one and not
6377 the other using intptr_t.
6379 2003-07-08 Kevin Ryde <user42@zip.com.au>
6381 * numbers.c (scm_make_polar): Use sincos, when available.
6382 (scm_magnitude): Use hypot.
6384 * ports.c (scm_char_ready_p, scm_peek_char): In docstrings, don't use
6385 @footnote since it doesn't go through to guile-procedures.txt.
6387 * threads.c (scm_call_with_new_thread): In docstring, use "( )"
6388 outside @var to quieten makeinfo, and use @code.
6390 2003-07-06 Han-Wen Nienhuys <hanwen@cs.uu.nl>
6392 * gc-malloc.c (decrease_mtrigger): new function
6393 (increase_mtrigger): new function, separate debug registering and
6394 mtrigger administration.
6395 (scm_gc_realloc): bugfix: do mtrigger administration before the
6396 actual realloc, for the realloc might invalidate a GC-d segment of
6397 memory. Thanks to Sam Hocevar for pointing this out.
6398 (scm_gc_realloc): use scm_malloc_reregister instead of
6399 unregistering and registering in sequence.
6401 2003-07-03 Han-Wen Nienhuys <hanwen@cs.uu.nl>
6403 * __scm.h (SCM_ASSERT): change "else" expansion to "do { } while (0)"

6427 2003-06-21 Kevin Ryde <user42@zip.com.au>
6429 * numbers.c (_GNU_SOURCE): #define, to get C99 things.
6430 (scm_asinh, scm_acosh, scm_atanh, scm_truncate, $asinh, $acosh,
6431 $atanh, truncate): Use C library asinh, acosh, atanh and trunc, when
6433 (scm_inexact_to_exact): Expand isfinite to its definition !xisinf.

6447 * threads.h: Redefined scm_getspecific() and scm_setspecific()
6448 to be functions instead of macros.
6450 * threads.c: Conditionalized inclusion of <sys/time.h> and
6452 (scm_getspecific, scm_setspecific): Made these two function
6453 real part of the API.
6455 * posix.c (s_scm_putenv): Added some code to make a
6456 (putenv "FOO="), i.e. setting an empty string, work also on
6457 Win32 systems. Thanks to Kevin Ryde for the proposal.
6459 2003-06-12 Kevin Ryde <user42@zip.com.au>
6461 * posix.c (scm_putenv): Free temporary ptr in mingw unset. Add

6482 scm_tcs_closures): Hard coded values replaced by symbolic ones.
6484 2003-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
6486 * eval.c: Partially undid my patch from 2003-05-31. This patch
6487 caused the segfault referenced in the previous changelog entry.
6489 2003-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
6491 * tags.h: Fixed comment about the immediate type code layout.
6493 * eval.c: Fixed handling of non-special instructions. Without
6494 this patch, guile will segfault on (#\0) and similar instructions.
6496 2003-06-05 Kevin Ryde <user42@zip.com.au>
6498 * numbers.c (scm_max, scm_min): For inum, bignum and real, if other
6499 operand is NaN, then return NaN. Also avoid passing NaN to mpz_cmp_d.
6501 * read.c (scm_input_error): Pass arg list parameter to scm_error_scm,
6502 rather than SCM_EOL. Needed by "Unknown # object" case in scm_lreadr.
6504 2003-06-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
6506 * __scm.h, gc-card.c (SCM_DEBUG_DEBUGGER_SUPPORT,
6507 SCM_DEBUG_DEBUGGING_SUPPORT): Renamed macro
6508 SCM_DEBUG_DEBUGGER_SUPPORT to SCM_DEBUG_DEBUGGING_SUPPORT and
6509 generalized it to apply not only to C level functions but also to
6510 scheme level functions.

6513 scm_iloc_p, dbg-make-iloc, scm_dbg_make_iloc, dbg-iloc?,
6514 scm_dbg_iloc_p): Moved functions scm_make_iloc, scm_iloc_p to
6515 eval.c, made them available under SCM_DEBUG_DEBUGGING_SUPPORT == 1
6516 only and renamed them to scm_dbg_make_iloc, scm_dbg_iloc_p,
6519 * deprecated.h, eval.c, eval.h (SCM_ILOC00, SCM_IDINC,
6520 SCM_IDSTMSK): Deprecated. The macro definitions are moved from
6521 eval.h into eval.c and a copy is placed into deprecated.h.
6523 * eval.c, eval.h (SCM_MAKE_ILOC): Removed from eval.h and placed
6524 into eval.c. This definition was not part of the API in any
6525 officially released version of guile and thus does not need to go
6526 through a phase of deprecation.
6528 2003-06-02 Dirk Herrmann <D.Herrmann@tu-bs.de>
6530 * deprecated.c, deprecated.h, eval.c, eval.h (scm_s_expression,
6531 scm_s_test, scm_s_body, scm_s_bindings, scm_s_variable,
6532 scm_s_clauses, scm_s_formals): Deprecated. In eval.c the
6533 definitions are make static and renamed from scm_s_xxx to s_xxx.
6534 In deprecated.c the original definitions are copied.
6536 * deprecated.h, eval.c, eval (SCM_EVALIM2, SCM_EVALIM, SCM_XEVAL,
6537 SCM_XEVALCAR): Deprecated. The macro definitions are moved from
6538 eval.h into eval.c and a copy (slightly modified to work in user
6539 code) is placed into deprecated.h.
6541 * eval.c: Use the local static s_xxx definitions instead of the
6542 scm_s_xxx definitions throughout.
6544 2003-06-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
6546 This set of patches separates the representation of the cxr family
6547 of functions (car, cdr etc.) from the dsubr family of functions
6548 (i. e. functions that take a double precision floating point
6549 argument). Further, the algorithm for handling the cxr function

6572 end of an if-else-if-sequence of checks.
6574 2003-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
6576 * eval.c (SCM_CEVAL): Improved readability of call-with-values
6577 execution. Generalize apply_closure to apply_proc and use that
6578 for call-with-values.
6580 2003-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
6582 * eval.c (SCM_CEVAL): Avoid one level of indirection when applying

6606 * posix.c (s_scm_putenv): Disable use of unsetenv() for the
6609 * modules.c (s_scm_module_import_interface): Renamed local
6610 variable interface to _interface. Seems like 'interface'
6611 is a special compiler directive for the mingw32 compiler.
6613 * mkstemp.c: Provide prototype to avoid compiler warning.
6615 * load.c (s_scm_search_path): Fixed absolute and relative
6616 path detections for native Windows platforms.
6618 * gc.h, threads.h: Export some more symbols using SCM_API (necessary

6751 * eval.c, eval.h, read.c, read.h (scm_sym_dot): Moved from eval to

6767 The purpose of this patch is to make guile's internal memoizers
6768 distinguishable from memoizing macros created on the scheme level
6769 or from user provided primitive memoizing macros. The reason is,
6770 that the internal memoizers are the only ones that are allowed to
6771 transform their scheme input into memoizer byte code, while all
6772 other memoizing macros may only transform scheme code into new
6775 To achieve this, a new macro type 'builtin-macro!' is introduced.
6776 Currently, 'builtin-macro!'s are handled as memoizing macros, but
6777 this will change when the memoizer and executor are separated.
6779 * macros.[ch] (scm_i_makbimacro): New.

6824 * goops.c: Removed binding of @dispatch.
6826 2003-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
6828 * eval.c, goops.c (@dispatch, @slot-ref, @slot-set!): Move the
6829 instructions that bind the macros on the scheme level back to
6830 goops.c in order to make sure again that the bindings go into the
6831 (oop goops) module and are not visible from the outside.
6833 2003-04-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
6835 * eval.c: Non functional change: Separated R5RS and non-R5RS

6878 This set of patches contains no functional changes, only debatable
6879 minor stylistic ones. Still, in order to prepare a patch between
6880 my local copy and the CVS version, I decided to submit the changes
6881 below. Then, the patch will hopefully only contain relevant
6884 * eval.c (iqq): Added const specifier.
6886 * eval.c (scm_trampoline_0, scm_trampoline_1, scm_trampoline_2):
6887 Use NULL instead of 0 to indicate that a pointer is returned.
6888 Removed some misleading 'fall through' comments.

6918 cmp_fun_t): Removed.
6920 (compare_function): Added.
6922 * sort.c (quicksort, SWAP, stack_node): Replaced pointer
6923 arithmetics with index arithmetics. Changed quicksort to work on
6924 an array of SCM values instead of an array of characters. Avoid
6925 bytewise copying of SCM elements. Avoid allocating memory on the
6926 stack with alloca. Fixed some comments.
6928 2003-04-21 Dirk Herrmann <D.Herrmann@tu-bs.de>

6940 compiling with SCM_DEBUG==1 by moving definition behind prototype.
6942 * gc.card.c (scm_dbg_t_list_cell, scm_dbg_t_double_cell,
6943 scm_dbg_gc_marked_p, scm_dbg_gc_get_card, scm_dbg_gc_get_bvec,

6945 scm_gc_marked_p, scm_gc_get_card, scm_gc_get_bvec): Fixed
6946 functions such that they check if the object is a non-immediate.
6947 Further, renamed identifiers to use the scm_dbg_ prefix and made
6948 their inclusion into the lib dependent of the
6949 SCM_DEBUG_DEBUGGER_SUPPORT compile time option.
6951 2003-04-21 Dirk Herrmann <D.Herrmann@tu-bs.de>

6958 * list.c (scm_ilength, scm_last_pair), unif.c (l2ra): Prefer
6959 !SCM_CONSP over SCM_NCONSP. Now, guile itself does not include
6960 any calls to SCM_NCONSP any more.
6962 * unif.c (l2ra): Eliminate redundant check.
6964 2003-04-21 Dirk Herrmann <D.Herrmann@tu-bs.de>

6982 2003-04-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
6984 * eval.c, eval.h, evalext.c, evalext.h (scm_sym_setter,
6985 scm_m_generalized_set_x, scm_init_evalext): Move the declaration
6986 and definition of the memoizer for the generalized set! macro from

6988 define the macro object.
6990 * eval.c, eval.h (s_set_x, scm_s_set_x, scm_m_set_x,
6991 scm_m_generalized_set_x): Since now scm_s_set_x is only used in

7003 * eval.c, eval.h (scm_f_apply, scm_init_eval): Made scm_f_apply
7004 static in eval.c, renamed it to f_apply and registered the object
7005 as a permanent object.
7007 2003-04-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
7009 * eval.c (SCM_BIT7, SCM_BIT8, unmemocopy, SCM_CEVAL): Renamed
7010 file-local macro SCM_BIT8 to SCM_BIT7, which is more appropriate.
7012 2003-04-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
7014 * numbers.c (scm_logtest): Fixed argument bug in the call to

7072 2003-04-13 Rob Browning <rlb@defaultvalue.org>
7074 * __scm.h (SCM_FLUSH_REGISTER_WINDOWS): don't just rely on "sparc"
7076 #if defined (sparc) || defined (__sparc__) || defined (__sparc)
7077 as gc_os_dep.c suggests is appropriate.
7079 * goops.c (prep_hashsets): make static to match prototype.
7080 (scm_sym_args): SCM_SYMBOL -> SCM_GLOBAL_SYMBOL. Thanks to Albert
7083 * c-tokenize.lex: remove trailing comma from enum. Thanks to

7116 * init.c: #include gmp.h.
7118 * numbers.h: remove the gmp.h #include (not needed now).
7120 * posix.h: change occurences of "id" to something else so we don't
7121 cause trouble when included via objective-c (can't hurt, might
7122 help). Still have usage in debug.h, though.
7124 2003-04-06 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7126 * random.c (scm_c_random_bignum): Don't generate a random number

7495 SCM_INLINE_C_INCLUDING_INLINE_H to 1 and #include
7496 "libguile/inline.h". scmconfig.h will define SCM_C_INLINE as
7497 appropriate, and we use that in inline.h along with the above

7578 * convert.h: rename usage of HAVE_ARRAYS to SCM_HAVE_ARRAYS.
7580 * convert.c: #include <config.h> if HAVE_CONFIG_H. Rename usage
7581 of HAVE_ARRAYS to SCM_HAVE_ARRAYS.
7583 * continuations.c: move libguile/_scm.h include to the top so we
7584 pick up any critical defines like _GNU_SOURCE early.

7605 (HAVE_LONG_LONGS): definition removed (see NEWS).
7606 (HAVE_LONG_LONG): definition removed (see NEWS).
7607 (HAVE_PTRDIFF_T): definition removed (see NEWS).
7609 * Makefile.am: scmconfig.h is now generated by building and
7610 running gen-scmconfig.h and capturing its output. gen-scmconfig
7611 uses config.h and the configure.in generated gen-scmconfig.h to
7612 decide what to output. See gen-scmconfig.c for details.
7613 (noinst_PROGRAMS): add gen-scmconfig.
7614 (gen_scmconfig_SOURCES): new variable.
7615 (gen-scmconfig.$(OBJEXT)): new target - be careful to handle
7616 cross-compiling right.
7617 (scmconfig.h): build scmconfig.h from gen-scmconfig's output.
7618 (BUILT_SOURCES): add scmconfig.h.

7641 2003-03-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
7643 * procs.c (scm_procedure_documentation): Removed redundant

7660 generic if not enabled.
7661 (scm_sys_goops_loaded): Setup unextended primitive generics.
7663 * goops.c, goops.h (scm_c_extend_primitive_generic): New function.
7665 * snarf.h (SCM_PRIMITIVE_GENERIC, SCM_PRIMITIVE_GENERIC_1): New
7668 * numbers.c (scm_abs): Use SCM_PRIMITIVE_GENERIC. (This is only a
7669 testing example. All uses of SCM_GPROC should be converted.)
7671 * procprop.c (scm_stand_in_scm_proc): Use scm_assq instead of
7674 * eq.c (scm_equal_p): Turned into a primitive generic.
7676 2003-02-27 Rob Browning <rlb@defaultvalue.org>
7678 * Makefile.am (scmconfig.h): new target -- generate file from
7680 (modinclude_HEADERS): remove version.h.
7681 (nodist_modinclude_HEADERS): add version.h.
7683 2003-02-24 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7685 This fixes a serious GC bug, introduced during the latest
7686 reorganization of the GC, which disabled freeing of structs and
7689 * struct.c (scm_struct_prehistory): Init scm_i_structs_to_free to
7691 (scm_struct_prehistory): Move scm_free_structs to
7692 scm_before_mark_c_hook.
7694 * gc-card.c (sweep_card): Check that we haven't swept structs on
7695 this card before. That can happen if scm_i_sweep_all_segments has
7696 been called from some other place than scm_igc.
7698 2003-02-19 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7700 * environments.c (DEFAULT_OBARRAY_SIZE): Changed from 137 to 31
7701 (since hash tables now adapt their size).
7703 * modules.c (scm_modules_prehistory): Changed from 2001 to 1533
7704 (current number of prehistory bindings; hashtable code will select
7705 a prime which is greater than this value).
7707 * symbols.c (scm_symbols_prehistory): Changed from 1009 to 2139
7708 (current number of initial symbols).

7711 scm_properties_whash.
7713 * objprop.c (scm_init_objprop): Don't specify size of
7716 * keywords.c (scm_init_keywords): Don't specify a hash table size.
7718 * hooks.c (scm_c_hook_add): Fixed bug in append mode.
7720 The following changes introduce the use of resizable hash tables
7721 throughout Guile. It also renames the old *-hash-table* functions
7722 to *-alist-vector* and places them, together with the rest of the
7723 weak vector support, in the module (ice-9 weak-vector). We should
7724 probably introduce a new, better, API for weak references, for
7725 example "weak pairs" a la MIT-Scheme. (In Chez scheme, they even
7726 look like and are used like ordinary pairs.)
7728 * environments.c (obarray_enter, obarray_retrieve, obarray_remove,
7729 leaf_environment_fold, obarray_remove_all): Use hashtable
7732 * gc.c (scm_init_storage): Moved hook initialization to
7733 scm_storage_prehistory.

7740 SCM_WVECT_WEAK_VALUE_P.
7742 * hashtab.c, hashtab.h (scm_hash_for_each, scm_hash_map): New
7744 (scm_vector_to_hash_table, scm_c_make_resizing_hash_table):
7746 (scm_make_weak_key_hash_table, scm_make_weak_value_hash_table,
7747 scm_make_doubly_weak_hash_table): Moved here from weaks.c.
7749 * init.c (scm_init_guile_1): Removed call to scm_init_weaks; Added
7750 calls to scm_storage_prehistory and scm_hashtab_prehistory.
7752 * modules.c (module-reverse-lookup): Use hashtable accessors.
7754 * symbols.c, symbols.h (scm_i_hash_symbol): New function.
7756 * weaks.c, weaks.h (scm_make_weak_key_alist_vector,
7757 scm_make_weak_value_alist_vector,
7758 scm_make_doubly_weak_alist_vector): New functions.
7760 * weaks.c (scm_init_weaks_builtins): New function.
7762 * weaks.h (SCM_WVECTF_WEAK_KEY, SCM_WVECTF_WEAK_VALUE,
7763 SCM_WVECTF_NOSCAN, SCM_WVECT_WEAK_KEY_P, SCM_WVECT_WEAK_VALUE_P,
7764 SCM_WVECT_NOSCAN_P): New macros.
7766 * weaks.c (scm_scan_weak_vectors): Use SCM_WVECT_WEAK_KEY_P
7767 and SCM_WVECT_WEAK_VALUE_P.
7769 * weaks.c, weaks.h (scm_i_allocate_weak_vector): Renamed from
7770 allocate_weak_vector and exported.
7772 2003-02-13 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7774 * hashtab.c: Undid thread safety. (We decided that it's better to
7775 let the user explicitly protect the tables (or not) according what
7776 is suitable for the application.)
7778 2003-02-12 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7780 * hashtab.c (scm_hash_fn_remove_x, scm_internal_hash_fold): Made
7781 thread safe and handle resizing tables.
7782 (scm_ihashx, scm_sloppy_assx, scm_delx_x): Removed
7783 SCM_DEFER/ALLOW_INTS.
7785 2003-02-11 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7787 * hashtab.c (scm_vector_to_hash_table,
7788 scm_c_make_resizing_hash_table, scm_make_hash_table): New
7790 (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x): Made thread
7791 safe and handle resizing tables.
7793 * weaks.c (scm_make_weak_key_hash_table,
7794 scm_make_weak_value_hash_table, scm_make_doubly_weak_hash_table):
7795 Size argument made optional. Return resizable table if not
7798 2003-02-10 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7800 * eval.c (scm_trampoline_0, scm_trampoline_1, scm_trampoline_2):
7801 Fixed formals tests for closures. (Thanks to Kevin Ryde.)
7803 2003-02-05 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7805 * debug.c (scm_procedure_source): Handle all objects for which
7806 procedure? is #t. (Thanks to Bill Schottstaedt.)
7808 2003-01-23 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7810 * futures.c (mark_futures): Don't need to mark data of recycled
7812 (scan_futures, cleanup_undead): Be smarter about marking
7813 futures---avoid unnecessary passes through future lists.
7815 * futures.h, futures.c: New files; Introduced recycling of
7816 futures. For fine-grained threading this lifts performance to
7817 another level. We can now use parallelization in inner loops of
7818 Guile programs without impossible overhead.
7820 * threads.h, threads.c: Moved futures to their own file.
7822 * Makefile.am (libguile_la_SOURCES): Added futures.c.
7823 (DOT_X_FILES): Added futures.x.
7824 (DOT_DOC_FILES): Added futures.doc.

7834 * init.c: #include "futures.h"
7835 (scm_init_guile_1): Call scm_init_futures.
7837 * stime.c (SCM_TIME_UNITS_PER_SECOND): Renamed from CLKTCK.
7839 * stime.h (SCM_TIME_UNITS_PER_SECOND): Definition moved here.
7841 * eval.c, eval.h (scm_trampoline_0, scm_i_call_closure_0): New
7844 * eval.c (scm_trampoline_1): Fixed arguments test for closures.
7846 2003-01-22 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7848 * threads.c (create_thread): Don't unwind dynwind chain of parent
7849 thread before creation. Just start the new thread with an empty
7852 2003-01-20 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7854 * evalext.c, evalext.h (scm_self_evaluating_p): New function.
7856 2003-01-10 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7858 * threads.c (scm_timed_wait_condition_variable): Support timed
7859 waiting also for simple condition variables.
7861 * goops.c (TEST_CHANGE_CLASS): Use scm_change_object_class instead
7862 of calling the procedure change-object-class.
7864 2003-01-09 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7866 * ramap.c (scm_ramapc): Typo in error message.
7868 2003-01-08 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7870 * goops.c (scm_sys_prep_layout_x): Bugfix: Only create layout for
7871 slots with instance allocation.
7873 * goops.c, goops.h (scm_class_extended_generic_with_setter): New
7875 (scm_compute_applicable_methods): Use scm_generic_function_methods.
7877 * goops.c (scm_generic_function_methods): Support extended
7880 2002-12-29 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7882 * eval.c (unmemocopy): Bugfix: scm_sym_delay --> scm_sym_future.
7883 Thanks to Neil for pointing this out!
7885 2002-12-29 Neil Jerram <neil@ossau.uklinux.net>
7887 * lang.h: Remove declarations matching definitions removed from
7888 lang.c (just below).
7890 2002-12-28 Neil Jerram <neil@ossau.uklinux.net>
7892 * lang.c (scm_nil_cons, scm_nil_car, scm_nil_cdr, scm_null,
7893 scm_m_while, scm_nil_eq): Remove definitions that were superfluous
7894 and already commented out.
7896 * read.h (scm_lreadparen), read.c (scm_lreadr, scm_read_token,
7897 scm_lreadparen): Support reading vectors with Elisp syntax if
7898 SCM_ELISP_READ_EXTENSIONS is defined. (SCM_ELISP_READ_EXTENSIONS
7899 is not currently defined, and there isn't even a configure switch
7902 2002-12-26 Marius Vollmer <mvo@zagadka.ping.de>
7904 * Makefile.am (c-tokenize.o): Refer to source via $< so that vpath
7906 (EXTRA_DIST): Added version.h.in.
7908 2002-12-21 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7910 This change makes it possible for one thread to do lazy sweeping
7911 while other threads are running. Now only the mark phase need to
7912 have all threads asleep. We should look further into this issue.
7913 Presently, I've put the locking of scm_i_sweep_mutex at
7914 "conservative" places due to my current lack of knowledge about
7915 the garbage collector. Please feel free to restrict these regions
7916 further to allow for maximal parallelism!
7918 * gc.c, gc.h (scm_i_sweep_mutex): New mutex.
7920 * gc.c (scm_gc_for_newcell), gc-malloc.c (scm_realloc,
7921 scm_gc_register_collectable_memory): Substitute locking of
7922 scm_i_sweep_mutex for calls to scm_i_thread_put_to_sleep.
7923 (scm_igc): Lock sweep mutex here instead of in callers; Calls to
7924 scm_i_thread_put_to_sleep/scm_i_thread_wake_up used to demarkate
7925 the single-thread section (which now only contains the mark
7927 (scm_gc): Don't lock sweeo mutex here since scm_igc locks it;
7928 Removed SCM_DEFER/ALLOW_INTS. Simply call scm_igc directly.
7930 * threads.c (gc_section_mutex): Removed.
7932 2002-12-19 Mikael Djurfeldt <mdj@kvast.blakulla.net>
7934 * threads.c (create_thread): Clear parent field in root state in
7935 order not to unnecessarily remember dead threads.
7937 * eval.c (call_subr2o_1, call_lsubr2_2): New functions.
7938 (scm_trampoline_1, scm_trampoline_2): Use them.
7940 2002-12-18 Mikael Djurfeldt <mdj@kvast.blakulla.net>
7942 Partial introduction of real plugin interface.
7944 * Makefile.am (modinclude_HEADERS): Added threads-plugin.h.
7945 (EXTRA_DIST): Added threads-plugin.c.
7947 * threads-plugin.h, threads-plugin.c: New files.
7949 * threads.h: #include "libguile/threads-plugin.h".
7951 * threads.c: #include "libguile/threads-plugin.c".
7953 * pthread-threads.c: Temporarily remove debugging functions.
7955 * threads.c, threads.h (scm_yield): Added back.
7957 2002-12-18 Mikael Djurfeldt <mdj@kvast.blakulla.net>
7959 * threads.c (really_launch): Detach before unlocking
7960 thread_admin_mutex in order not to risk being joined.
7961 (scm_i_thread_put_to_sleep, scm_i_thread_wake_up): Keep
7962 thread_admin_mutex locked during GC.
7964 * pthread-threads.c, pthread-threads.h: Improvements to debugging
7967 2002-12-16 Mikael Djurfeldt <mdj@kvast.blakulla.net>
7969 * pthread-threads.c, pthread-threads.h (SCM_DEBUG_THREADS): Added
7970 support for debugging mutex operations.
7972 * threads.c (scm_thread): Removed filed joining_threads.
7973 (thread_print): Print thread number as well as address of thread
7975 (scm_join_thread): Bugfix.
7976 (scm_lock_mutex, scm_try_mutex, scm_unlock_mutex,
7977 scm_timed_wait_condition_variable, scm_signal_condition_variable,
7978 scm_broadcast_condition_variable): Use the low-level API.
7979 (scm_all_threads): Return copy of thread list (to prevent
7980 unintended destruction).
7981 (scm_threads_prehistory): Initialize heap_mutex of fake thread.
7983 * pthread-threads.c, pthread-threads.h, threads.c: Fixes to
7984 pthread "native" recursive mutex support.
7986 2002-12-15 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7988 * __scm.h (SCM_DEFER_INTS, SCM_ALLOW_INTS): New definitions.
7989 Simply lock a thread C API recursive mutex.
7990 (SCM_NONREC_CRITICAL_SECTION_START,
7991 SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START,
7992 SCM_REC_CRITICAL_SECTION_END): Removed.
7994 * eval.c: Replaced SOURCE_SECTION_START / SOURCE_SECTION_END with
7995 direct calls to scm_rec_mutex_lock / unlock around the three calls
7996 to scm_m_expand_body.
7998 * eval.c, eval.h (promise_free): New function.
7999 (scm_force): Rewritten; Now thread-safe; Removed
8000 SCM_DEFER/ALLOW_INTS.
8002 * pthread-threads.h: Added partially implemented plugin interface
8003 for recursive mutexes. These are, for now, only intended to be
8004 used internally within the Guile implementation.
8006 * pthread-threads.c: New file.
8008 * threads.c: Conditionally #include "pthread-threads.c".
8010 * eval.c, eval.h (scm_makprom, scm_force): Rewritten to be
8013 * snarf.h (SCM_MUTEX, SCM_GLOBAL_MUTEX, SCM_REC_MUTEX,
8014 SCM_GLOBAL_REC_MUTEX): New macros.
8016 * eval.c, threads.c, threads.h, snarf.h: Rewrote critical section
8017 macros---use mutexes instead.
8019 * tags.h (SCM_IM_FUTURE): New tag.
8021 * eval.c (scm_m_future): New primitive macro.
8022 (SCM_CEVAL): Support futures.
8023 (unmemocopy): Support unmemoization of futures.
8025 * print.c (scm_isymnames): Name of future isym.
8027 * version.c: Unmade some changes to my private copy that got
8028 committed by mistake.
8030 2002-12-11 Mikael Djurfeldt <mdj@kvast.blakulla.net>
8032 * gc-malloc.c, gc.h, init.c: Reverted gc-malloc change of
8035 * gc.c (scm_igc): Don't call scm_i_thread_invalidate_freelists.
8037 * gc.c (scm_gc_sweep): Call it here instead, which is a more
8040 * threads.c (create_thread): Remember root object until the handle
8041 of the new thread is on all_threads list.
8043 * root.c (scm_make_root): Moved copying of fluids until after
8044 creation of root handle so that the fluids are GC protected. Also
8045 removed the critical section.
8047 2002-12-10 Mikael Djurfeldt <mdj@kvast.blakulla.net>
8049 * gc-malloc.c, gc.h (scm_gc_malloc_prehistory): New function.
8051 * gc-malloc.c (malloc_mutex): New mutex.
8052 (scm_gc_malloc_prehistory): Initialize it.
8053 (scm_realloc): Serialize call to realloc
8054 (scm_calloc): Same for calloc.
8055 Thanks to Wolfgang Jaehrling!
8056 (Now we have to make sure all calls to malloc/realloc are made
8057 through scm_malloc.)
8059 * init.c (scm_init_guile_1): Call scm_gc_malloc_prehistory.
8061 * threads.c (really_launch): Release heap (to prevent deadlock).
8062 (create_thread): Release heap before locking thread admin mutex.
8064 2002-12-10 Mikael Djurfeldt <mdj@kvast.blakulla.net>
8066 * threads.c (scm_i_thread_invalidate_freelists): New
8069 * gc.c (scm_igc): Call scm_i_thread_invalidate_freelists.
8071 * modules.c (scm_export): Inserted a return statement.
8073 2002-12-10 Han-Wen Nienhuys <hanwen@cs.uu.nl>
8075 * modules.c (scm_export): new function
8077 * gc-card.c: add a note about malloc()/free() overhead.
8079 2002-12-10 Mikael Djurfeldt <mdj@kvast.blakulla.net>
8081 * Makefile.am (c-tokenize.$(OBJEXT)): Don't look for c-tokenize.c
8084 2002-12-10 Mikael Djurfeldt <djurfeldt@nada.kth.se>
8086 These changes remove scm_ints_disabled (which hasn't has any
8087 effect in Guile for quite some time).
8089 * async.c, error.h (scm_ints_disabled): Removed.
8091 * gc.c (scm_gc_for_newcell), init.c (scm_init_guile_1),
8092 root.c (scm_internal_cwdr), gdbint.c (SCM_BEGIN_FOREIGN_BLOCK,
8093 SCM_END_FOREIGN_BLOCK): Don't touch scm_ints_disabled.
8094 (old_ints): Removed.
8096 * __scm.h (SCM_DEFER_INTS, SCM_ALLOW_INTS): Define as a recursive
8098 (SCM_REDEFER_INTS, SCM_ALLOW_INTS): Define as SCM_DEFER_INTS and
8101 2002-12-09 Mikael Djurfeldt <djurfeldt@nada.kth.se>
8103 * threads.c (scm_mutex_lock, scm_cond_wait, scm_cond_timedwait):
8104 Removed accidental #if 0 around these functions.
8106 These changes are the start of support for preemptive
8107 multithreading. Marius and I have agreed that I commit this code
8108 into the repository although it isn't thoroughly tested and surely
8109 introduces many bugs. The bugs should only be exposed when using
8110 threads, though. Signalling and error handling for threads is
8111 very likely broken. Work on making the implementation cleaner and
8112 more efficient is needed.
8114 * __scm.h (SCM_ALLOW_INTS_ONLY): Removed.
8115 (SCM_NONREC_CRITICAL_SECTION_START,
8116 SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START,
8117 SCM_REC_CRITICAL_SECTION_END): New macros.
8118 (SCM_CRITICAL_SECTION_START/END): Defined here.
8120 * eval.c: Insert SOURCE_SECTION_START / SOURCE_SECTION_END around
8121 the three calls to scm_m_expand_body.
8123 * gc.h: #include "libguile/pthread-threads.h";
8124 (SCM_FREELIST_CREATE, SCM_FREELIST_LOC): New macros.
8126 * gc.c (scm_i_freelist, scm_i_freelist2): Defined to be of type
8129 * gc.c, gc-freelist.c, inline.h: Use SCM_FREELIST_LOC for freelist
8132 * gc-freelist.c (scm_gc_init_freelist): Create freelist keys.
8134 * gc-freelist.c, threads.c (really_launch): Use
8135 SCM_FREELIST_CREATE.
8137 * gc-malloc.c (scm_realloc, scm_gc_register_collectable_memory):
8139 * gc.c (scm_i_expensive_validation_check, scm_gc,
8140 scm_gc_for_newcell): Put threads to sleep before doing GC-related
8141 heap administration so that those pieces of code are executed
8142 single-threaded. We might consider rewriting these code sections
8143 in terms of a "call_gc_code_singly_threaded" construct instead of
8144 calling the pair of scm_i_thread_put_to_sleep () and
8145 scm_i_thread_wake_up (). Also, we would want to have as many of
8146 these sections eleminated.
8148 * init.c (scm_init_guile_1): Call scm_threads_prehistory.
8150 * inline.h: #include "libguile/threads.h"
8152 * pthread-threads.h: Macros now conform more closely to the
8153 pthreads interface. Some of them now take a second argument.
8155 * threads.c, threads.h: Many changes.
8157 2002-12-09 Mikael Djurfeldt <djurfeldt@nada.kth.se>
8159 * Makefile.am (version.h): Changed $^ --> $< in rule for
8162 2002-12-08 Rob Browning <rlb@defaultvalue.org>
8164 * version.h.in (SCM_MICRO_VERSION): use @--@ substitution now.
8165 (SCM_MINOR_VERSION): use @--@ substitution now.
8166 (SCM_MICRO_VERSION): use @--@ substitution now.
8167 (scm_effective_version): new function prototype.
8169 * version.c (scm_effective_version): new function, also add
8172 * Makefile.am (schemelibdir): VERSION -> GUILE_EFFECTIVE_VERSION.
8173 (libpath.h): use GUILE_EFFECTIVE_VERSION to compute
8175 (version.h): generate this here rather than configure.in. This
8176 approach tracks source edits better (i.e. more immediately).
8177 Might be worth considering for other .in files too.
8179 2002-12-02 Marius Vollmer <mvo@zagadka.ping.de>
8181 Reorganized thread package selection. A thread package now only
8182 implements a small set of pthread like functions and Guile
8183 implements the rest on top of that. Guile's implementation is
8184 what the "coop-pthreads" package has been previously. Support for
8185 "coop" threads has been removed until I get time to add it again.
8187 * Makefile.am (libguile_la_SOURCES): Removed iselect.c.
8188 (noinst_HEADERS): Removed coop-threads.c, coop-threads.h, coop.c,
8189 null-threads.c, coop-pthreads.c.
8190 (modinclude_HEADERS): Removed coop-defs.h, coop-pthreads.h. Added
8193 * validate.h (SCM_VALIDATE_THREAD): Moved to threads.h.
8195 * threads.h: Do not include "libguile/coop-defs.h". Include
8196 "libguile/pthread-threads.h" for USE_COPT_THREADS. Removed
8197 (previously deprecated) C level thread API prototypes. They are
8198 now in the thread package specific headers, "null-threads.h" and
8199 "pthread-threads.h".
8200 (SCM_VALIDATE_THREAD, SCM_VALIDATE_MUTEX, SCM_VALIDATE_CONDVAR):
8202 (scm_threads_init): Removed.
8203 (SCM_CRITICAL_SECTION_START, SCM_CRITICAL_SECTION_END,
8204 SCM_THREAD_SWITCHING_CODE, scm_i_switch_counter,
8205 SCM_I_THREAD_SWITCH_COUNT): Define here.
8206 (scm_single_thread_p): Removed.
8207 (scm_call_with_new_thread): Take two args directly instead of list
8209 (scm_i_thread_data, scm_i_set_thread_data, SCM_THREAD_LOCAL_DATA,
8210 SCM_SET_THREAD_LOCAL_DATA): Define here.
8212 * threads.c: Merged with "coop-pthreads.c".
8214 * null-threads.h: Implement pthread-like API as a set of macros.
8216 * pthread-threads.h: New, implement pthread-like API by deferring
8219 * init.c (scm_init_guile_1): Do not call scm_init_iselect, which
8220 has been lost in the reorganization.
8222 2002-12-01 Mikael Djurfeldt <mdj@linnaeus>
8224 The following change makes it possible to move procedure
8225 application dispatch outside inner loops. The motivation was
8226 clean implementation of efficient replacements of R5RS primitives
8229 The semantics is clear: scm_trampoline_N returns an optimized
8230 version of scm_call_N (or NULL if the procedure isn't applicable
8233 Applying the optimization to map and for-each increases efficiency
8234 noticeably. For example, (map abs ls) is 8 times faster than
8237 * eval.h (scm_t_trampoline_1, scm_t_trampoline_2): New types.
8239 * eval.c, eval.h (scm_trampoline_1, scm_trampoline_2): New functions.
8241 * eval.c (call_subr2_2, call_lsubr_2, call_closure_2): New functions;
8242 (map, for-each): Handle also application on two args as a special
8243 case; Use trampolines.
8247 * sort.c (scm_cmp_function): Choose subr2less for scm_tc7_subr_2o;
8248 (subr2oless): Removed.
8249 (scm_restricted_vector_sort_x): Use scm_return_first to keep the
8250 vector GC protected.
8252 * eval.c (check_map_args): Use scm_out_of_range_pos instead of
8255 2002-11-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
8257 * evalext.[ch] (scm_m_undefine, undefine): Deprecated.
8259 2002-11-17 Mikael Djurfeldt <mdj@linnaeus>
8261 * debug.c (scm_make_iloc): Added missing "return".
8263 2002-11-17 Marius Vollmer <mvo@zagadka.ping.de>
8265 * strports.c (scm_eval_string_in_module): Validate second arg to
8266 be a module. Thanks to Arno Peters!
8268 2002-11-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
8270 * .cvsignore: remove goops.c
8272 2002-11-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
8274 * modules.c (scm_env_top_level, scm_lookup_closure_module,
8275 module_variable, scm_module_lookup_closure,
8276 scm_module_transformer, scm_sym2var, scm_module_reverse_lookup,
8277 scm_system_module_env_p): Don't compare SCM values with C
8278 operators == or !=. Avoid SCM_IMP predicates. Prefer !SCM_FALSEP
8281 2002-11-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
8283 * eval.h (SCM_MAKE_ILOC): New macro.
8285 * debug.c (scm_make_iloc): Use SCM_MAKE_ILOC instead of computing
8286 the iloc bitpattern here.
8288 2002-11-14 Mikael Djurfeldt <mdj@linnaeus>
8290 * coop-pthreads.c, coop-pthreads.h: scm_internal_select should be
8291 part of the API, otherwise it's difficult to write Guile
8292 extensions using non-blocking I/O => moved #include
8293 "libguile/iselect.h" from coop-pthreads.c --> coop-pthreads.h.
8295 * coop-pthreads.c (scm_unlock_mutex): Changed s_lock_mutex -->
8298 2002-11-10 Marius Vollmer <mvo@zagadka.ping.de>
8300 * __scm.h (USE_THREADS, GUILE_ISELECT): Do not define here. They
8301 are defined in configure.in.
8303 * threads.c: Removed SCM_API from function definitions. SCM_API
8304 is only for declarations.
8306 2002-11-07 Mikael Djurfeldt <mdj@linnaeus>
8308 * coop-pthreads.h: Added support for thread specific data to the
8309 generic C API for the coop-pthreads case.
8311 * threads.c, threads.h (scm_cond_init): Undo unintentional API
8313 (scm_cond_broadcast): Added missing function.
8315 2002-11-04 Marius Vollmer <marius.vollmer@uni-dortmund.de>
8317 * coop.c (coop_next_runnable_thread): Removed, wich should have
8318 happened when GUILE_ISELECT was hard-wired.
8320 2002-11-03 Marius Vollmer <mvo@zagadka.ping.de>
8322 * Makefile.am (libguile_la_SOURCES): Added threads.c
8323 (DOT_DOC_FILES): Added threads.doc.
8324 (DOT_X_FILES): Added threads.x.
8325 (EXTRA_libguile_la_SOURCES): Removed threads.c.
8326 (noinst_HEADERS): Added coop-pthreads.c.
8327 (modinclude_HEADERS): Added coop-pthreads.h.
8329 * __scm.h (USE_THREADS, GUILE_ISELECT): Define when
8330 SCM_DEBUG_DEPRECATED. Removed their use thru-out Guile.
8332 * iselect.c: Include "_scm.h" before testing HAVE_UNISTD_H.
8333 Thanks to Bill Schottstaedt!
8335 * numbers.c (scm_integer_expt): Make 0^z == 0 for z != 0.
8337 * _scm.h (HAVE_RESTARTABLE_SYSCALLS): Do define even when
8338 SCM_COPT_THREADS is defined.
8339 (SCM_SYSCALL): Use EINTR-expection version when SCM_COPT_THREADS
8342 * coop-pthreads.c: Some harmless renamings of internal stuff.
8343 (create_thread): New, generalized version of
8344 scm_call_with_new_thread.
8345 (scm_call_with_new_thread): Use it.

8860 * gc-malloc.c (scm_calloc): add scm_calloc.
8862 2002-08-05 Han-Wen Nienhuys <hanwen@cs.uu.nl>
8864 * tags.h: remove GC bits documentation from the tags table.
8866 * read.c (INPUT_ERROR): Prepare for file:line:column error
8867 messages for errors in scm_lreadr() and friends.
8869 2002-08-04 Han-Wen Nienhuys <hanwen@cs.uu.nl>
8871 * gc-malloc.c (scm_malloc): use scm_realloc() (simplifies
8873 (scm_gc_calloc): new function
8875 2002-08-04 Han-Wen Nienhuys <hanwen@cs.uu.nl>
8877 * ports.c (scm_new_port_table_entry): init port entry to 0
8880 * ports.c (scm_new_port_table_entry): change function from
8881 scm_add_to_port_table. This prevents cells with null-pointers from
8882 being exposed to GC.
8884 * vports.c (scm_make_soft_port) strports.c (scm_mkstrport),
8885 fports.c (scm_fdes_to_port): Use scm_new_port_table_entry().
8887 * gc.c (scm_gc_stats): add cell-yield and malloc-yield statistic
8890 * numbers.c (big2str): return "0" for 0 iso. ""
8892 * gc-segment.c, gc-malloc.c gc-mark.c, gc-freelist.c, gc-card.c,
8893 private-gc.h: new file
8895 * gc.c: completely revised and cleaned up the GC. It now uses lazy
8896 sweeping. More documentation in workbook/newgc.text
8898 2002-07-25 Marius Vollmer <marius.vollmer@uni-dortmund.de>
8900 * random.c (rstate_free): Return zero.
8902 2002-07-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
8904 * environments.c (remove_key_from_alist): Removed.
8906 (obarray_remove): Simplified.
8908 2002-07-24 Stefan Jahn <stefan@lkcc.org>
8910 * continuations.h: ia64: Include <signal.h> before
8913 2002-07-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
8915 * modules.c (scm_sym2var): Don't compare SCM values with ==.
8917 2002-07-21 Han-Wen Nienhuys <hanwen@cs.uu.nl>
8919 * goops.c (scm_compute_applicable_methods): use
8920 scm_remember_upto_here_1 iso scm_remember_upto_here
8922 * macros.c: include deprecation.h
8924 * vectors.c (scm_vector_move_right_x): remove side effect in
8926 (scm_vector_move_left_x): idem.
8928 * net_db.c, posix.c, socket.c: variable naming: change ans to
8931 * sort.c (scm_merge_vector_x): accept vector as argument
8932 iso. SCM*. This is needed for full GC correctness.
8934 * gc.h: undo previous undocumented changes related to #ifdef
8937 2002-07-20 Han-Wen Nienhuys <hanwen@cs.uu.nl>
8939 * *.c: add space after commas everywhere.
8941 * *.c: use SCM_VECTOR_SET everywhere, where a vector is written.
8942 Document cases where SCM_WRITABLE_VELTS() is used.
8944 * vectors.h (SCM_VELTS): prepare for write barrier, and let
8945 SCM_VELTS() return a const pointer
8946 (SCM_VECTOR_SET): add macro.
8948 2002-07-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
8950 * eval.c (SCM_CEVAL), macros.c (macro_print, scm_makmacro,
8951 scm_sym_macro, scm_macro_type), macros.h (scm_makmacro):
8952 Deprecated the special kind of built-in dynamic syntax transformer
8953 that was inaccurately named "macro". Note: The built-in syntax
8954 transformers that are named "mmacro" or "memoizing-macro" still
8955 exist, and it is these which come much closer to what one would
8958 2002-07-13 Neil Jerram <neil@ossau.uklinux.net>
8960 * eval.c (unmemocopy): Fix for
8961 1001-local-eval-error-backtrace-segfaults (unmemoization crash
8962 with internal definitions and local-eval).
8964 2002-07-12 Gary Houston <ghouston@arglist.com>
8966 * dynl.c: Don't define stub procedures if DYNAMIC_LINKING is not
8967 defined. They don't do anything useful, especially since the
8968 only case where DYNAMIC_LINKING is undefined seems to be
8969 when --with-modules=no is given to configure, which is basically
8970 requesting that the "dynamic linking module" be omitted.
8972 * Makefile.am (libguile_la_SOURCES): move dynl.c from
8973 libguile_la_SOURCES to EXTRA_libguile_la_SOURCES.
8975 * extensions.c (load_extension): check DYNAMIC_LINKING for
8977 * init.c (scm_init_guile_1): check DYNAMIC_LINKING for
8978 scm_init_dynamic_linking.
8980 2002-07-10 Marius Vollmer <mvo@zagadka.ping.de>
8982 * guile.c, iselect.h, net_db.c, posix.c, socket.c: No need to
8983 check for Cygwin when including <winsock2.h>, this is already
8984 check for by configure. Thus, revert change from 2002-07-07.
8986 2002-07-10 Gary Houston <ghouston@arglist.com>
8988 * eq.c: include <string.h>
8989 * dynl.c: docstring editing.
8991 2002-07-09 Gary Houston <ghouston@arglist.com>
8993 * dynl.c (scm_dynamic_call): docstring editing.
8995 2002-07-08 Rob Browning <rlb@defaultvalue.org>
8997 * gc_os_dep.c: HURD fixes.
8999 2002-07-07 Marius Vollmer <mvo@zagadka.ping.de>
9001 Crosscompiling and Cygwin fixes by Jan Nieuwenhuizen. Thanks!
9003 * Makefile.am: Override default rule for c-tokenize.$(OBJECT);
9004 this should be compiled for BUILD host.
9005 Override default rule for
9006 guile_filter_doc_snarfage$(EEXECT); this should run on BUILD host.
9007 Add missing $(EXEEXT) to guile_filter_doc_snarfage invocation.
9008 (snarf2checkedtexi): Use GUILE_FOR_BUILD instead of preinstguile.
9010 * guile.c, iselect.h, net_db.c, posix.c, socket.c: Do not include
9011 <winsock2.h> on Cygwin even when we have it.
9013 2002-07-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
9015 * __scm.h (SCM_CAUTIOUS), eval.c (scm_eval_args, deval_args,
9016 SCM_CEVAL): Removed compile time option SCM_CAUTIOUS to clean up
9017 the code. Full number of arguments checking of closures is
9018 mandatory now. However, the option to disable the checking has
9019 most probably not been used anyway.
9021 2002-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
9023 * __scm.h (SCM_RECKLESS), backtrace.c (SCM_ASSERT), debug.c
9024 (scm_debug_options), eval.c (scm_lookupcar, scm_lookupcar1,
9025 scm_badargsp, SCM_CEVAL, SCM_APPLY, scm_map, scm_for_each),
9026 feature.c (scm_init_feature), gsubr.c (scm_gsubr_apply), numbers.c
9027 (scm_logand, scm_logior, scm_logxor, scm_i_dbl2big), srcprop.c
9028 (scm_source_properties, scm_set_source_properties_x,
9029 scm_source_property): Removed compile time option SCM_RECKLESS to
9030 clean up the code. Full number of arguments checking of closures
9031 is mandatory now. However, the option to disable the checking has
9032 most probably not been used anyway.
9034 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
9035 scm_source_property): Use !SCM_CONSP instead of SCM_NCONSP.
9037 2002-06-30 Gary Houston <ghouston@arglist.com>
9039 * dynl.c: Removed all SCM_DEFER_INTS/SCM_ALLOW_INTS, which won't
9040 do anything useful. Added a comment about need for a mutex if
9041 pre-emptive threading is supported.
9043 * posix.c (scm_convert_exec_args), dynl.c
9044 (scm_make_argv_from_stringlist): static procs: 1) renamed both to
9045 allocate_string_pointers. 2) simplified: don't reallocate the
9046 strings, just make an array of pointers 3) avoid memory leaks on
9047 error 4) let the procedure report errors in its own name.
9048 Consequences: 1) the procedures now assume that SCM strings are
9049 nul-terminated, which should always be the case. 2) Since strings
9050 are not reallocated, it's now possible for strings passed to
9051 dynamic-args-call to be mutated.
9053 2002-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
9055 * __scm.h, eval.c, eval.h: Removed compile time option
9056 MEMOIZE_LOCALS to clean up the code. Now, caching of local
9057 variable positions during memoization is mandatory. However, the
9058 option to disable the caching has most probably not been used
9061 2002-06-18 Marius Vollmer <mvo@zagadka.ping.de>
9063 * print.c (scm_simple_format): Print missing part of format before
9064 ~% control. Thanks to Daniel Skarda!
9066 2002-06-01 Marius Vollmer <mvo@zagadka.ping.de>
9068 * mkstemp.c: Added exception notice to license statement.
9070 2002-05-22 Marius Vollmer <mvo@zagadka.ping.de>
9072 * numbers.c (mem2ureal): When returning an inexact zero, make sure
9073 it is represented as a floating point value so that we can change
9076 From John W. Eaton <jwe@bevo.che.wisc.edu>
9078 * numbers.c (idbl2str): Don't omit sign when printing negative zero.
9080 2002-05-14 Thien-Thi Nguyen <ttn@giblet.glug.org>
9082 * gc_os_dep.c: For I386/OPENBSD, allow for `__i386__'
9083 in addition to `i386'. Thanks to Dale P. Smith.
9085 2002-05-08 Marius Vollmer <mvo@zagadka.ping.de>
9087 * eq.c (real_eqv): New.
9088 (scm_eqv_p): Use it when comparing reals and complexes.
9090 * numbers.c: Include <string.h>, for strncmp.
9091 (mem2complex): Do not create negative NaNs.
9092 (scm_leq_p, scm_geq_p): Explicitely return #f when comparing a
9094 (scm_inexact_to_exact): Signal error when converting a NaN.
9096 2002-05-06 Marius Vollmer <mvo@zagadka.ping.de>
9098 * posix.c (scm_putenv): Handle removing variables explicitely by
9103 * numbers.h: Conditionally include floatingpoint.h, ieeefp.h, and
9104 nan.h. Provide declarations for scm_inf_p, scm_nan_p, scn_inf,
9106 * numbers.c: [SCO && ! HAVE_ISNAN] (isnan): New function.
9107 [SCO && ! HAVE_ISINF] (isinf): New function.
9108 (xisinf, xisnan): New functions.
9110 (isfinite): Define in terms of xisinf.
9111 (scm_inf_p, scm_nan_p): New functions.
9112 (guile_Inf, guile_NaN): New file-scope vars.
9113 (guile_ieee_init): New function.
9114 (scm_inf, scm_nan): New functions.
9115 (idbl2str): Handle Inf and NaN. Remove funny label and
9116 corresponding gotos.
9117 (ALLOW_DIVIDE_BY_ZERO): New macro.
9118 (scm_divide): Allow division by zero to occur if
9119 ALLOW_DIVIDE_BY_ZERO is defined.
9120 Handle bignums and ints as special cases.
9122 Additional stuff by me:
9124 numbers.c (mem2ureal): Recognize "inf.0" and "nan.xxx".
9125 (scm_even_p, scm_odd_p): Treat infinity as even and odd.
9126 (iflo2str): Don't output a '+' for negative numbers or for Inf and
9127 NaN. They will provide their own sign.
9128 (scm_divide): Only allow divides by inexact zeros. Dividing by
9129 exact zeros still signals an errors.
9131 2002-04-22 Thien-Thi Nguyen <ttn@giblet.glug.org>
9133 * goops.h (scm_slot_exists_p): Rename from scm_slots_exists_p.
9134 * goops.c (scm_slot_exists_p): Rename from scm_slots_exists_p.
9135 (scm_slot_exists_p): Rename from scm_slots_exists_p.
9136 Thanks to Andreas Rottmann.
9138 2002-04-20 Gary Houston <ghouston@arglist.com>
9140 * removal of unused fields in root state (thanks to Christopher
9141 Cramer for pointing out the disuse.)
9142 * root.h (scm_root_state): removed def_inp, def_outp, def_errp.
9143 (scm_def_inp, scm_def_outp, scm_def_errp): removed.
9145 * root.c (root_mark): don't mark them.
9146 (scm_make_root): don't set them to #f.
9147 * init.c (scm_init_standard_ports): don't initialise with the
9150 2002-04-17 Marius Vollmer <mvo@zagadka.ping.de>
9152 * Makefile.am (EXTRA_DIST): Added cpp_err_symbols.c and
9155 2002-04-16 Marius Vollmer <mvo@zagadka.ping.de>
9157 * guile-snarf.in: Do not clean input file. This would write to
9158 the $(srcdir) during a VPATH build, which is not allowed. It also
9159 isn't needed since it only works when an output filename has been
9160 specified and in that case we don't need to clean the input file
9161 because the output file will already exist.
9163 2002-03-31 Marius Vollmer <mvo@zagadka.ping.de>
9165 * guile-snarf: Install the trap for removing $cleanfile only when
9166 the value of $cleanfile is actually known.
9168 2002-04-10 Rob Browning <rlb@defaultvalue.org>
9170 * .cvsignore: add versiondat.h and *.c.clean.c.
9172 2002-03-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
9174 * srcprop.[ch] (scm_c_source_property_breakpoint_p): New
9175 function, replaces macro SRCBRKP.
9177 (SRCBRKP): Deprecated.
9179 * eval.c (SCM_CEVAL): Replaced use of SRCBRKP by call to
9180 scm_c_source_property_breakpoint_p. Removed some use of arg1 as
9183 2002-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
9185 * debug.h, eval.c: Deprecated CHECK_ENTRY, CHECK_APPLY and
9186 CHECK_EXIT and removed all references to them.
9188 2002-03-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
9190 * debug.h (scm_ready_p, debug_print): Removed declarations.
9192 * eval.c (EVALCELLCAR): Removed.
9194 (SCM_CEVAL): Eliminated label loopnoap. Removed side-effecting
9195 operation from condition.
9197 2002-03-24 Marius Vollmer <mvo@zagadka.ping.de>
9199 * guile-snarf.in: When the output filename is "-", write to
9200 stdout. When no "-o" option is given, use "-" as the output
9201 filename (i.e., stdout). Only 'clean' the inputfile or remove the
9202 output file on error when the output file name is not "-". Define
9203 the preprocessor macro SCM_MAGIC_SNARFER while snarfing.
9205 * Makefile.am (.c.x): Pass "-o $@" to guile-snarf.
9207 2002-03-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
9209 * eval.c (SCM_CEVAL, SCM_APPLY): Eliminated labels wrongnumargs
9210 and the corresponding goto statements. Removed redundant code.
9212 2002-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
9214 * eval.c (SCM_CEVAL): Minimized scope of variable arg2.
9215 Eliminated redundant SCM_IMP check. Exlined call to EVALCAR.
9216 Re-enabled handing of rpsubrs and asubrs.
9218 2002-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
9220 * eval.c (SIDEVAL): Removed.
9222 (SCM_CEVAL): Minimized scope of variable orig_sym. Eliminated
9223 goto-labels cdrxnoap, cdrxbegin and nontoplevel_cdrxnoap. Changed
9224 argument checking order for set! to locals, variables and symbols.
9225 Improvements to control structure. Removed some uses of arg1 and
9226 arg2 as temporary variables.
9228 2002-03-15 Thien-Thi Nguyen <ttn@giblet.glug.org>
9230 * guile-snarf.in: Remove "--compat=1.4" support.
9231 Add "-d" and "-D" support.
9233 (deprecated_list): New var.
9234 (compat_mode_clean_xxx): Delete.
9235 (grep_deprecated): New func.
9236 ("main"): If "-d" or "-D", call `grep_deprecated'.
9238 2002-03-15 Neil Jerram <neil@ossau.uklinux.net>
9240 * hooks.h: Change scm_t_c_hookype_t everywhere to
9245 * strings.c (scm_string_p): Change unnecessary `iff' to `if'.
9247 * ports.c (scm_sys_make_void_port): Use `@file'.
9249 * numbers.c (scm_number_p, scm_real_p): Use `otherwise' rather
9252 * macros.c (scm_makmacro): Don't say that the form replaces its
9253 source, because it doesn't.
9254 (scm_makmmacro): Clarify difference between this and scm_makmacro.
9256 * backtrace.c (scm_display_error), filesys.c (scm_umask,
9257 scm_select, scm_basename), goops.c (scm_method_generic_function),
9258 numbers.c (scm_integer_length), posix.c (scm_getgroups, scm_execl,
9259 scm_setlocale, scm_flock), socket.c (scm_shutdown): Correct
9262 * debug.c (scm_debug_options), eval.c
9263 (scm_eval_options_interface), read.c (scm_read_options): Change
9264 incorrect @var in docstring to @code.
9266 2002-03-14 Marius Vollmer <mvo@zagadka.ping.de>
9268 * unif.c (singp): Use SCM_REALP instead of SCM_SLOPPY_REALP.
9270 * snarf.h (SCM_SNARF_INIT): Add "^:^" after code so that
9271 guile-snarf can remove trailing non-init code.
9273 * guile-snarf.in (modern_snarf): Remove everything following and
9274 including "^:^" from the output.
9276 2002-03-14 Dirk Herrmann <D.Herrmann@tu-bs.de>
9278 * eval.c (SCM_CEVAL), srcprop.h (SRCBRKP): Eliminated union 't'.

9284 * guile-snarf.in: Update copyright.
9285 Rewrite to internalize error handling.
9286 Add "--compat=1.4" handling.
9289 * Makefile.am (libpath.h): Use @top_srcdir_absolute@.
9290 (snarfcppopts): New var.
9291 (.c.x): Use $(snarfcppopts). Rework guile-snarf usage.
9292 (.c.doc): Use $(snarfcppopts).
9294 * alist.c, arbiters.c, async.c, backtrace.c, boolean.c, chars.c,
9295 continuations.c, debug-malloc.c, debug.c, deprecation.c, dynl.c,
9296 dynwind.c, environments.c, eq.c, error.c, eval.c, evalext.c,
9297 extensions.c, feature.c, filesys.c, fluids.c, fports.c, gc.c,
9298 goops.c, gsubr.c, guardians.c, hash.c, hashtab.c, hooks.c,

9306 unif.c, values.c, variable.c, vectors.c, version.c, vports.c,
9307 weaks.c: Retire inclusion guard macro SCM_MAGIC_SNARFER.
9309 2002-03-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
9311 * eval.c (SCM_CEVAL): Got rid of the last reference to t.lloc.
9312 The next step will be to remove the union 't' and simplify the
9313 code of SCM_CEVAL that way.
9315 2002-03-12 Neil Jerram <neil@ossau.uklinux.net>
9317 * iselect.c (collisionp, gnfds, greadfds, gwritefds, gexceptfds,
9318 rreadfds, rwritefds, rexceptfds): Made static.
9320 * gc.c (terminating), fports.c (terminating): Renamed
9323 2002-03-11 Marius Vollmer <mvo@zagadka.ping.de>
9325 * numbers.c (scm_divide): Adapt code from libstdc++/f2c to void
9326 potential overflow problems. Thanks to John W Eaton!
9328 * strop.c (string_capitalize_x): Treat characters as unsigned so
9329 that 8-bit chars work. Thanks to David Pirotte!
9331 2002-03-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
9333 * eval.c (SCM_CEVAL): Cleaned up the handling of 'slot-ref',
9334 'slot-set!' and 'nil-cond'. Removed some uses of t.arg1, arg2 and
9335 proc as temporary variables. Introduced temporary variables with
9336 hopefully descriptive names for clarification. Replaced SCM_N?IMP
9337 by a more explicit predicate in some places.
9339 2002-03-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
9341 * eval.c (SCM_CEVAL): Cleaned up the handling of #@dispatch.
9342 Added lots of comments regarding the implementation of #@dispatch.
9343 Changed intra-procedure communication to use t.arg1 instead of
9344 arg2. Removed some uses of t.arg1, t.lloc and proc as temporary
9345 variables. Introduced temporary variables with hopefully
9346 descriptive names for clarification. Replaced SCM_N?IMP by a more
9347 explicit predicate in some places. Use SCM_INSTANCE_HASH instead
9348 of computing the expression explicitly. Eliminate now unused
9349 label nontoplevel_cdrxbegin.
9351 * goops.h (SCM_INSTANCE_HASH): New macro.
9353 * objects.h (SCM_CMETHOD_FORMALS, SCM_CMETHOD_BODY): New macros.
9355 2002-03-08 Thien-Thi Nguyen <ttn@giblet.glug.org>
9357 * Makefile.am (bin_SCRIPTS): Revive this decl, w/ initial element
9358 "guile-snarf" moved back from `noinst_SCRIPTS'.
9360 2002-03-08 Neil Jerram <neil@ossau.uklinux.net>
9362 * srcprop.c (scm_set_source_property_x): If SRCPROPS obj already
9363 exists when adding a source property other than those that are
9364 handled explicitly, add the new property to the SRCPROPS obj's
9367 * debug.h (SCM_MAX_FRAME_SIZE): Remove incorrect comment about use
9368 of SCM_MAX_FRAME_SIZE as a bit mask; it isn't used like this.
9370 * eval.c (SCM_CEVAL): Don't store scm_debug_eframe_size in
9371 debug.status. It isn't needed, and it can overflow the bits

9390 as temporary variables. Removed side-effecting operations from
9391 conditions and macro calls. Introduced temporary variables with
9392 hopefully descriptive names for clarification. Replaced SCM_N?IMP
9393 by a more explicit predicate in some places. Removed code that
9394 was conditionally compiled if SICP was defined - which it never
9397 2002-03-02 Dirk Herrmann <D.Herrmann@tu-bs.de>

9414 variables. Removed side-effecting operations from conditions and
9415 macro calls. Introduced temporary variables for clarification.
9416 Sorted if-else-if check for the type of the last form in a list by
9417 frequency. Avoided some unnecessary tail-recursion calls.

9844 invalid unused variable name: `OMIT_DEPENDENCIES'
9846 2001-11-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
9848 * numbers.c (scm_divide): Fix (/ 0). Thanks to Keith Wright for
9851 2001-11-21 Marius Vollmer <mvo@zagadka.ping.de>
9853 * Makefile.am (install-exec-hook): Prepend $(DESTDIR) to filename.
9854 Thanks to Eric Gillespie, Jr!
9856 2001-11-21 Stefan Jahn <stefan@lkcc.org>
9858 * win32-socket.c (getservent, setservent, endservent,
9859 getprotoent, setprotoent, endprotoent): New functions.
9860 Appropriate replacements for M$-Windows.
9862 * numbers.c (SIZE_MAX, PTRDIFF_MAX, PTRDIFF_MIN): Reintroduced
9863 these definitions for GUILE_DEBUG.
9865 * net_db.c: Include "win32-socket.h" if compiling with a native
9866 M$-Windows compiler. Include some pieces of code (protoent and
9867 servent interface) protected by HAVE_* macros when using a
9868 native M$-Windows compiler.
9870 2001-11-20 Marius Vollmer <mvo@zagadka.ping.de>
9872 * modules.c (scm_c_export): Do nothing when the first argument is
9873 already the terminating NULL. Thanks to Han-Wen Nienhuys!
9875 2001-11-20 Thien-Thi Nguyen <ttn@glug.org>
9877 * Makefile.am (libpath.h): In SCM_BUILD_INFO,
9878 also include `buildstamp'.
9880 2001-11-18 Rob Browning <rlb@defaultvalue.org>
9883 (s_scm_major_version): use SCM_MAJOR_VERSION.
9884 (s_scm_minor_version): use SCM_MINOR_VERSION.
9885 (s_scm_micro_version): use SCM_MICRO_VERSION.
9886 (s_scm_version): use SCM_MAJOR_VERSION, SCM_MINOR_VERSION, and
9890 (SCM_MAJOR_VERSION): renamed from SCM_GUILE_MAJOR_VERSION.
9891 (SCM_MINOR_VERSION): renamed from SCM_GUILE_MINOR_VERSION.
9892 (SCM_MICRO_VERSION): renamed from SCM_GUILE_MICRO_VERSION.
9894 2001-11-18 Neil Jerram <neil@ossau.uklinux.net>
9896 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
9897 Rewrite docstrings without reference to substring-move-left/right,
9898 since the latter no longer exist.
9900 2001-11-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
9902 * eval.c: Removed bogus comment about acros.
9904 (scm_unmemocar): Use !SCM_CONSP instead of SCM_IMP.
9905 Minimize scope of local variable. Eliminate dependency on
9906 macro DEBUG_EXTENSIONS.
9908 (s_splicing): New error message string.
9910 (scm_m_body): Issue 'bad body' message rather than 'missing
9911 expression' message.
9913 (scm_m_quote): Eliminate unnecessary copying.
9915 (scm_m_lambda, scm_m_letstar, scm_m_letrec, scm_m_let): Leave the
9916 checking of the body to scm_m_body.
9918 (scm_m_do): Move comment to function header. Rename arg1 to
9919 binding. Made the code a bit easier to read.
9923 (iqq): Added a comment. Changed the depth parameter to
9924 unsigned. Use size_t for vector lengths. Make sure vector object
9925 is gc protected as long as its contents are read. Add some syntax
9926 checks. Get rid of unnecessary SCM_IMP test. Clean up the
9927 control structure a bit.
9929 (scm_m_delay): Added comment about the implementation of
9932 (scm_m_define): Add comment about guile's currying define
9933 syntax. Renamed 'proc' to 'name'. Eliminate dependency on macro
9934 DEBUG_EXTENSIONS. Simplified code a bit. Eliminate SICP code.
9936 (scm_m_letrec1): Removed. Part of the functionality is taken
9937 over by the new function 'transform_bindings'.
9939 (transform_bindings): New function. Takes over some of the
9940 functionality of removed function 'scm_m_letrec1', namely to split
9941 a list of bindings into a reversed list of variables and a list of
9944 (scm_m_letrec): Call 'transform_bindings'.
9946 (scm_m_let): Minimized scope of local variables. Renamed 'proc'
9947 to 'temp' and 'arg1' to 'binding'. Eliminated redundant SCM_NIMP
9948 test. Use 'transform_bindings'. Fixed scoping error with named
9949 let (Thanks to Aubrey Jaffer for reporting the bug and to Neil
9950 Jerram for suggesting the fix). Cleaned up the control structure
9953 (scm_m_expand_body): Use 'transform_bindings'. Eliminated
9954 unnecessary consing. Eliminated unnecessary
9955 SCM_DEFER/ALLOW_INTS.
9957 (SCM_CEVAL): Un-obfuscated some loops.
9959 2001-11-16 Neil Jerram <neil@ossau.uklinux.net>
9961 * gc.h (scm_unhash_name): Old declaration removed.
9963 * eval.c (s_scm_eval): Change @var{primitive-eval} to
9964 @code{primitive-eval}.
9966 * feature.c, vectors.c, net_db.c, unif.c, weaks.c, struct.c,
9967 version.c, alist.c, ports.c, ramap.c, unif.c, strings.c, list.c:
9968 Change @deffnx lines in docstrings to say {Scheme Procedure}
9969 rather than primitive or procedure.
9971 * posix.c (scm_execl), filesys.c (scm_close), unif.c
9972 (scm_array_set_x, scm_array_contents, scm_uniform_array_read_x,
9973 scm_bit_set_star_x, scm_bit_invert_x), ramap.c (scm_array_fill_x,
9974 scm_array_for_each, scm_array_index_map_x), vectors.c (scm_vector,
9975 scm_make_vector, scm_vector_to_list, scm_vector_fill_x), strop.c
9976 (scm_string_split, scm_string_ci_to_symbol), strings.c
9977 (scm_string_p), sort.c (scm_merge), print.c (scm_newline),
9978 macros.c (scm_macro_type), alist.c (scm_acons, scm_assq):
9979 Docstring fixes and improvements reflecting edits that have been
9980 made in the reference manual source.
9982 * objprop.c (scm_object_properties, scm_set_object_properties_x,
9983 scm_object_property, scm_set_object_property_x): Remove invalid
9984 @deffnx lines for corresponding procedure property primitives.
9986 These changes add a @deffnx C function declaration and function
9987 index entries for each Guile primitive to the copy of the doc
9988 snarf output that is used for reference manual synchronization.
9989 Online help is unchanged.
9991 * snarf.h (SCM_SNARF_DOCS): Output primitive's C function name.
9992 (SCM_DEFINE, SCM_DEFINE1, SCM_REGISTER_PROC): Supply to C function
9993 name to SCM_SNARF_DOCS.
9995 * guile-snarf-docs-texi.in: Pass the shell script's arguments into
9996 snarf-check-and-output-texi.
9998 * Makefile.am (guile-procedures.texi): New rule.
9999 (BUILT_SOURCES, guile.texi, guile-procedures.txt, CLEANFILES):
10000 Changed so that the last stage of doc snarfing is now performed
10001 twice, once to produce guile-procedures.txt for online help, and
10002 once to produce guile.texi for reference manual synchronization.
10004 2001-11-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
10006 * eval.c (RETURN): Wrap in do{}while(0) in order to make it
10007 safely usable as a single statement followed by a ';', for example
10008 in an if statement.
10010 (SCM_CEVAL, SCM_APPLY): Clean up code using 'RETURN'.
10012 2001-11-13 Neil Jerram <neil@ossau.uklinux.net>
10014 * random.c (scm_random_solid_sphere_x,
10015 scm_random_hollow_sphere_x): Correct "shere" typos.
10017 * hashtab.c (scm_hash_fold): Add missing apostrophe to docstring.
10019 * version.c (scm_version): Update docstring to include
10022 2001-11-13 Marius Vollmer <mvo@zagadka.ping.de>
10024 * modules.c (scm_c_export): Call va_end after collecting the
10027 * strop.h, strop.c (scm_substring_move_left_x,
10028 scm_substring_move_right_x): Removed.
10030 * __scm.h (HAVE_UINTPTR_T, HAVE_PTRDIFF_T, HAVE_LONG_LONG,
10031 HAVE_LONG_LONGS): Define to "1" when defining them, to mirror what
10034 2001-11-12 Marius Vollmer <mvo@zagadka.ping.de>
10036 * numbers.c: Document macros to define when including
10037 num2integral.i.c. MAX_VALUE and MIN_VALU are no longer used, we
10038 now rely on SIZEOF_ macros that have been figured out at
10041 * num2integral.i.c: Adapt to new interface.
10042 (NUM2INTEGRAL): Test whether a fixnum can be represented in the
10043 target type by casting it and checking whether it is still the
10044 same. Do not try to handle bignums for integral types that are
10045 smaller than fixnums. When handling bignums, collect the
10046 magnituse first into a unsigned type, and correctly check for
10048 (INTEGRAL2BIG): Do not use MIN_VALUE explicitely by observing that
10049 only -MIN_VALUE can still be negative of all negative numbers (in
10052 * tags.h (SIZEOF_SCM_T_BITS): Define it appropriately.
10054 * __scm.h: Define HAVE_UINTPTR_T, HAVE_PTRDIFF_T and
10055 HAVE_LONG_LONG depending on whether their size is non-zero.
10057 2001-11-11 Thien-Thi Nguyen <ttn@glug.org>
10059 * strop.c (scm_string_null_p): Docfix; nfc.
10060 Thanks to Scott Lenser.
10062 2001-11-07 Neil Jerram <neil@ossau.uklinux.net>
10064 * extensions.c (scm_load_extension): Canonicalize docstring
10067 * unif.c (scm_uniform_array_write), ports.c
10068 (scm_current_output_port, scm_force_output), dynwind.c
10069 (scm_dynamic_wind), scmsigs.c (scm_setitimer, scm_getitimer),
10070 filesys.c (scm_open, scm_lstat), struct.c
10071 (scm_make_struct_layout), random.c (scm_random,
10072 scm_random_solid_sphere_x, scm_random_hollow_sphere_x, strop.c
10073 (scm_i_index): Remove superfluous whitespace from end of docstring
10076 * filesys.c (scm_select), guardians.c (scm_guardian_greedy_p),
10077 strings.c (scm_make_string), variable.c (scm_make_variable,
10078 scm_make_undefined_variable, scm_variable_p, scm_variable_set_x,
10079 scm_variable_bound_p), scmsigs.c (scm_setitimer, scm_getitimer),
10080 posix.c (scm_crypt), struct.c (scm_make_vtable_vtable), hashtab.c
10081 (scm_hash_fold), ports.c (scm_port_for_each): Remove superfluous
10082 newline at end of docstrings.
10084 * modules.c (scm_set_current_module): Add missing newline to
10087 2001-11-07 Stefan Jahn <stefan@lkcc.org>
10089 * win32-socket.[ch]: New files. Defines Winsock-API error codes
10090 and makes them available through Guile. That is because the
10091 Winsock-API does not store its errors in `errno' and thus cannot
10092 return error messages via `strerror (errno)'.
10094 * socket.c (scm_init_socket): Initialize `win32-socket' part
10095 here under M$-Windows.
10097 * numbers.h: Added missing declaration of
10098 `scm_sys_check_number_conversions()'.
10100 * error.c: Local definition of SCM_I_STRERROR and SCM_I_ERRNO
10101 and use in `(strerror)' and `(system-error)'.
10103 * Makefile.am (EXTRA_libguile_la_SOURCES): Added
10104 `win32-socket.[ch]' to extra source and header files.
10106 2001-11-06 Marius Vollmer <mvo@zagadka.ping.de>
10108 * script.c (scm_shell_usage, scm_compile_shell_switches): Prepend
10109 a call to turn-on-debugging when --debug has been given instead of
10110 turning it on directly. Also, handle new `--no-debug' option,
10111 which might suppress the call to turn-on-debugging.
10113 2001-11-05 Stefan Jahn <stefan@lkcc.org>
10115 * struct.c (s_scm_struct_vtable_p): Corrected docstring.
10117 2001-11-04 Stefan Jahn <stefan@lkcc.org>
10119 * Makefile.am (libguile_la_LIBADD): Added $(THREAD_LIBS_LOCAL)
10120 here (was at guile_LDADD) which describes the dependency
10121 correctly and allows a clean build on Win32.
10123 * __scm.h (SCM_API): Follow-up patch. Renamed __FOO__ macros
10126 * __scm.h: USE_DLL_IMPORT indicates the usage of the DLL
10127 import macros for external libraries (libcrypt, libqthreads,
10128 libreadline and libregex).
10130 * coop-defs.h: Include <winsock2.h> for `struct timeval'.
10132 * posix.c (flock): Added support for flock() in M$-Windows.
10134 * guile.c (SCM_IMPORT): Follow-up patch. Use SCM_IMPORT instead
10137 * fports.c (getflags): Differentiate reading and writing pipes
10140 * filesys.c (S_IS*): Redefine all of the S_IS*() macros for
10143 * coop.c (coop_condition_variable_timed_wait_mutex): Use
10144 conditionalized error code if `ETIMEDOUT' is not available.
10145 (scm_thread_usleep): Remove bogus declaration of `struct timeval
10148 * numbers.c (PTRDIFF_MIN): Moved this definition where it actually
10149 belongs. That is because NO_PREPRO_MAGIC gets undefined after
10150 each inclusion of `num2integral.i.c'.
10151 (SIZE_MAX): Define NO_PREPRO_MAGIC if SIZE_MAX is undefined.
10153 2001-11-03 Marius Vollmer <mvo@zagadka.ping.de>
10155 * eval.c (scm_m_begin): Allow `(begin)`, with no subforms.
10156 (SCM_CEVAL): Evaluate an empty `begin' to SCM_UNSPECIFIED.
10158 2001-11-02 Mikael Djurfeldt <mdj@linnaeus>
10160 * print.c (scm_iprin1): Mark print state as revealed when
10161 dispatching to generic write or display.
10163 * unif.c (scm_ra2contig): Fixed memory overwrite bug.
10165 2001-11-02 Marius Vollmer <mvo@zagadka.ping.de>
10167 Support for native Win32. Thanks to Stefan Jahn!
10169 * Makefile.am: Add win32-uname.c, win32-uname.h, win32-dirent.c
10170 and win32-dirent.h to extra source and header files. These
10171 include the uname() and the POSIX dirent interface implementation
10172 for M$-Windows. Put `-no-undefined' into LDFLAGS to support
10173 linkers which do not allow unresolved symbols inside shared
10174 libraries. Corrected `guile_filter_doc_snarfage$(EXEEXT)'
10177 * __scm.h: Defined SCM_API. This macro gets prepended to all
10178 function and data definitions which should be exported or imported
10179 in the resulting dynamic link library in the Win32 port.
10181 * __scm.h, alist.h, arbiters.h, async.h, backtrace.h, boolean.h,
10182 chars.h, continuations.h, coop-defs.h, coop-threads.h,
10183 debug-malloc.h, debug.h, deprecation.h, dynl.h, dynwind.h,
10184 environments.h, eq.h, error.h, eval.h, evalext.h, extensions.h,
10185 feature.h, filesys.h, fluids.h, fports.h, gc.h, gdb_interface.h,
10186 gdbint.h, gh.h, goops.h, gsubr.h, guardians.h, hash.h, hashtab.h,

10190 procprop.h, procs.h, properties.h, ramap.h, random.h, rdelim.h,
10191 read.h, regex-posix.h, root.h, rw.h, scmsigs.h, script.h, simpos.h,
10192 smob.h, socket.h, sort.h, srcprop.h, stackchk.h, stacks.h, stime.h,
10193 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
10194 tags.h, threads.h, throw.h, unif.h, values.h, variable.h, vectors.h,
10196 Prefixed each each exported symbol with SCM_API.
10198 * continuations.c: Added comment about the use of the extern
10199 declarations of {get,set}context() functions used in the ia64 port.
10201 * continuations.h, gc.c: `__libc_ia64_register_backing_store_base'
10202 is meant to be a `unsigned long *'.
10204 * filesys.c: Include `direct.h' if possible. Use local
10205 `win32-dirent.h' for the native M$-Windows port. Define S_IS*()
10206 macros for M$-Windows. Implementation of `fstat_Win32()' which is
10207 able to differentiate between sockets and other file descriptors.
10208 Use this function as wrapper in `scm_fstat()'. Fixed typo in
10211 * fports.c: Include `io.h' is possible. Put `*fp' into referring
10212 statement block in `scm_fport_buffer_add()'.
10213 Some corrections in `getflags()'.
10215 * gdb_interface.h (GDB_INTERFACE): Also support __CYGWIN__.
10217 * guile.c: Make sure to define __SCM_IMPORT__ for shared library
10218 build on Win32. Disable preloaded symbols on Win2 platforms.
10220 * ioext.c, ports.c: Include `io.h' is possible.
10222 * mkstemp.c: Include `process.h' is possible.
10224 * net_db.c: Disable extern declaration of `h_errno' for __CYGWIN__,
10226 Put `scm_return_entry()' into HAVE_GETSERVENT conditional.
10228 * posix.c: Remove unnecessary dirent includes and defines. Include
10229 local `win32-uname.h' for MinGW. Extern declaration of
10230 `mkstemp()' for systems where it does not exists. Make
10231 `getlogin()' available on M$-Windows.
10233 * scmsigs.c: Made `usleep()' avalable on MinGW.
10235 * stime.c: On M$-Windows `tzname[]' is known to be `_tzname[]'.
10237 * win32-dirent.c: Include "win32-dirent.h", not "dirent.h".
10239 * win32-uname.c: Include "win32-uname.h", not "uname.h".
10241 2001-10-28 Mikael Djurfeldt <mdj@linnaeus>
10243 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write):
10244 Don't apply scm_uniform_vector_length on arrays.
10246 2001-10-14 Dirk Herrmann <D.Herrmann@tu-bs.de>
10248 * eval.c (scm_lookupcar, scm_m_letstar, scm_m_do, iqq,
10249 scm_m_define, scm_m_letrec1, scm_m_let, scm_m_expand_body,
10250 scm_macroexp, unmemocopy, scm_eval_args, scm_deval_args,
10251 SCM_CEVAL, scm_map, scm_init_eval): When building lists, prefer
10252 scm_list_<n> over scm_cons[2]?.
10254 (scm_unmemocar, scm_m_cond, scm_m_letstar, scm_m_letrec1,
10255 scm_m_let, scm_m_atbind, unmemocopy, SCM_CEVAL, SCM_APPLY): Use
10256 SCM_C[AD][AD]R instead of explicit form.
10258 (scm_m_set_x, scm_m_cond, scm_m_letstar, scm_m_do): Reordered
10259 comparison parameters.
10261 (scm_m_case, scm_m_cond, scm_m_letstar, scm_m_do, SCM_CEVAL): Use
10262 !SCM_NULLP instead of SCM_NIMP.
10264 (scm_m_case): Don't copy the form. Renamed proc to clause and
10265 minimized its scope. Renamed x to clauses. Removed side
10266 effecting operation from macro call.
10268 (scm_m_cond): Don't copy the form. Renamed arg1 to clause and
10269 minimized its scope. Renamed x to clauses. Minimized the scope
10270 of variable 'len'. Make sure the else clause is treated specially
10271 even in case of '=>' occurences. Don't change the else to #t in
10272 order to be able to distinguish this case in the evaluator. Leave
10273 type checking of the recipient to the evaluator.
10275 (scm_c_improper_memq): Made the comment somewhat clearer.
10277 (scm_m_lambda): Renamed proc to formals. Removed unnecessary
10278 test for SCM_IM_LET at the place of the formal parameters.
10279 Simplified the formal parameter checking.
10281 (scm_m_letstar): Added Comment. Renamed proc to bindings.
10282 Renamed arg1 to binding and minimized its scope. Eliminated
10283 unnecessary consing.
10285 (scm_m_do): Renamed proc to bindings. Minimized the scope of
10288 (build_binding_list): New static function.
10290 (unmemocopy): Don't use SCM_TYP7 on pairs (it's unclean).
10291 Further, split up the 'letrec' unmemoizing code to the
10292 corresponding parts for 'do', 'let' and 'letrec', adding comments
10293 to each form. Cleanup the handling of the do form (This removes
10294 some *real* code :-).
10296 (SCM_CEVAL): Removed side effecting operation from macro call.
10297 Handle the 'else clause of the 'cond form specially - the symbol
10298 'else is not replaced with #t any more.
10300 2001-10-14 Gary Houston <ghouston@arglist.com>
10302 * version.c (scm_version): use sprintf instead of snprintf,
10303 for portability. thanks to Bill Schottstaedt.
10305 2001-10-14 Mikael Djurfeldt <mdj@linnaeus>
10307 * read.c (scm_lreadr): When user-defined hash procedure returns
10308 SCM_UNSPECIFIED: Fall back to standard handling instead of raising
10309 an exception. (This prevents parsing of uniform vectors from
10310 interfering with parsing of numbers.)
10312 2001-10-13 Marius Vollmer <mvo@zagadka.ping.de>
10314 * numbers.c: Set NO_PREPRO_MAGIC when defining our version of
10315 PTRDIFF_MIN. Thanks to Ken Raeburn.
10317 2001-10-07 Marius Vollmer <mvo@zagadka.ping.de>
10319 * Makefile.am (EXTRA_libguile_la_SOURCES): Added "mkstemp.c".
10321 * eval.c (scm_m_atbind): First try to find the variable without
10322 defining it locally; when it has not been found, define it
10325 * modules.c (module_variable): Pass over variables that exist but
10328 2001-10-06 Marius Vollmer <mvo@zagadka.ping.de>
10330 * backtrace.c (display_backtrace_file_and_line): Only use
10331 scm_basename when POSIX support is compiled in. Thanks to Chris
10334 2001-10-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
10336 * numbers.c (mem2uinteger): Return number read so far when coming
10337 across a hexdigit after having read a # or if not reading a hex
10338 value. This will enable the calling code to correctly handle
10339 forms like 1e2. (The background is, that the exponent markers d,
10340 e and f are also hexdigits.) Thanks to Mikael Djurfeldt for
10341 providing this patch.
10343 (mem2complex): Fix erroneous double-negation. Now, numbers like
10344 1-i will be read correctly.
10346 2001-10-12 Mikael Djurfeldt <mdj@linnaeus>
10348 * debug.c (scm_mem_to_proc): Fixed typo in previous change.
10350 * validate.h (SCM_VALIDATE_DOUBLE_DEF_COPY): New macro.
10352 2001-10-12 Dirk Herrmann <D.Herrmann@tu-bs.de>
10354 * print.c (scm_print_state_vtable, print_state_pool):
10355 Initialize. These variables are now registered as gc roots.
10357 (scm_current_pstate): Update documentation.
10359 (scm_current_pstate, scm_make_print_state, scm_free_print_state,
10360 scm_prin1, scm_init_print): print_state_pool is registered as a
10361 gc root and thus does not need to be protected by a surrounding
10364 (make_print_state): The car of print_state_pool no longer holds
10365 the scm_print_state_vtable.
10367 (scm_current_pstate, scm_make_print_state, print_circref,
10368 scm_iprin1, scm_prin1, scm_iprlist): Prefer !SCM_<foo> over
10371 (scm_prin1): When building lists, prefer scm_list_<n> over
10374 (scm_iprlist): Removed a redundant SCM_IMP test.
10376 (scm_simple_format): Use SCM_EQ_P to compare SCM values.
10378 2001-10-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
10380 * debug.c (scm_make_iloc): Prefer !SCM_<foo> over SCM_N<foo>.
10382 (scm_memcons, scm_mem_to_proc): When building lists, prefer
10383 scm_list_<n> over scm_cons[2]?.
10385 (scm_mem_to_proc): Prefer SCM_CONSP over SCM_NIMP.
10387 (scm_procedure_name): Use SCM_CADR instead of explicit form.
10389 (debugobj_print): Coerce scm_intprint arg 1 to long, not int.
10390 Thanks to Rob Browning for the patch (see log entry 2001-09-21) -
10391 for some reason his patch didn't make it into the cvs.
10393 2001-10-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
10395 * numbers.c (mem2decimal_from_point): Cleaned up the parsing a
10396 little bit - should even be somewhat more accurate now.
10398 2001-10-08 Rob Browning <rlb@defaultvalue.org>
10400 * gc.c: support ia64 register backing store.
10401 (SCM_MARK_BACKING_STORE): new macro.
10403 * continuations.h: support ia64 register backing store.
10404 (struct scm_t_contregs): add ia64 register backing store.
10406 * continuations.c: support ia64 register backing store.
10407 (continuation_mark): mark ia64 register backing store.
10408 (continuation_free): free ia64 register backing store.
10409 (scm_make_continuation): capture ia64 register backing store.
10410 (copy_stack_and_call): copy ia64 register backing store.
10412 2001-10-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
10414 * hashtab.c (scm_hash_fn_create_handle_x): The result of assoc_fn
10415 is known to be #f if no entry is found. Thus, use !SCM_FALSEP
10416 instead of SCM_NIMP to test for that case.
10418 * strings.h (SCM_SET_STRING_LENGTH): Cast the length to
10419 scm_t_bits instead of long.
10421 2001-10-06 Marius Vollmer <mvo@zagadka.ping.de>
10423 * tags.h (SCM_T_BITS_MAX, SCM_T_SIGNED_BITS_MAX,
10424 SCM_T_SIGNED_BITS_MIN): New.
10425 * numbers.h (SCM_MOST_POSITIVE_FIXNUM, SCM_MOST_NEGATIVE_FIXNUM):
10426 Use them to make these macros computable by the preprocessor.
10428 * num2integral.i.c (INTEGRAL2NUM): Let the preprocessor test
10429 whether the integral type fits in a fixnum, not the compiler.
10430 This removes a spurious compiler warning. Also, honor the
10431 NO_PREPRO_MAGIC flag to suppress any preprocessor tests. This is
10432 needed for `long long's.
10434 * numbers.c: Define NO_PREPRO_MAGOC when including
10435 num2integral.c.i for `long long' and `signed long long'.
10437 2001-10-06 Mikael Djurfeldt <mdj@linnaeus>
10439 These changes fixes a race condition in the Guile coop - pthread
10440 compatibility code.
10442 * coop.c (mother_awake_p): New variable.
10443 (coop_create): Set mother_awake_p before creating or signalling
10444 mother; wait until mother is going to sleep before returning.
10445 (mother): Reset mother_awake_p before going to sleep.
10447 2001-10-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
10449 * options.c (protected_objects, scm_init_options): The content of
10450 protected_objects is now protected from garbage collection using
10451 scm_gc_register_root instead of scm_permanent_object.
10453 (get_option_setting): New static function that computes an option
10454 setting as it was formerly done in the function scm_options.
10456 (get_documented_option_setting): New static function that
10457 returns option documentation as it was formerly done in the
10458 function scm_options. Note that documentation C strings are no
10459 longer precomputed into SCM objects. Instead, they are converted
10460 into SCM strings every time get_documented_option_setting is
10463 (change_option_setting): New static functions that modifies the
10464 option setting as it was formerly done in the function
10465 scm_options. The function is now exception safe, i. e. won't
10466 cause a memory leak when interrupted. Further, only non-immediate
10467 option values are added to the protection list.
10469 (scm_options): This function now has only the purpose to dispatch
10470 to to get_option_setting, get_documented_option_setting or
10471 change_option_setting, depending on the arguments given to
10474 (scm_init_opts): Don't convert documentation C strings into SCM
10475 strings. Further, don't protect any object values: They _must_
10476 be immediate values, otherwise there is no guarantee that they
10477 have not been collected before anyway.
10479 * options.[ch] (scm_t_option): Made type unsigned, name into a
10480 constant char* and val into a scm_t_bits type.
10482 (scm_options, scm_init_opts): The number of options is guaranteed
10483 to be larger or equal to zero. Thus, the type is changed to
10486 2001-10-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
10488 * num2integral.i.c (NUM2INTEGRAL): Eliminated some warnings about
10489 testing an unsigned value for being >= 0.
10491 2001-10-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
10493 * numbers.h: Removed old comment about using SCM_CAR to access
10496 (SCM_MOST_POSITIVE_FIXNUM, SCM_MOST_NEGATIVE_FIXNUM): Make sure
10497 the return value is signed. Thanks to Brian Crowder for the bug
10500 (SCM_SRS): Avoid unnecessary casting and don't unpack input
10501 values. With this patch, SCM_SRS can be safely used for other
10502 types than scm_t_signed_bits. However, it should still better be
10503 an internal macro and thus be renamed to SCM_I_SRS.
10505 (SCM_MAKINUM, SCM_INUM): Use proper casting.
10507 2001-10-03 Gary Houston <ghouston@arglist.com>
10509 * continuations.h, unif.h: in the descriptions of the bit patterns
10510 of the heap cells, make bit 0 the least significant.
10512 2001-09-25 Thien-Thi Nguyen <ttn@glug.org>
10514 * chars.h (SCM_MAKE_CHAR): Use `scm_t_bits' instead of `intptr_t'.
10515 Thanks to Golubev I. N.
10517 2001-09-25 Gary Houston <ghouston@arglist.com>
10519 * ports.c (scm_drain_input): extended the docstring. thanks to
10520 Alex Schroeder and Thien-Thi Nguyen.
10522 2001-09-23 Mikael Djurfeldt <mdj@linnaeus>
10524 * validate.h (SCM_NUM2FLOAT, SCM_NUM2DOUBLE,
10525 SCM_VALIDATE_FLOAT_COPY, SCM_VALIDATE_DOUBLE_COPY): New
10526 macros. (The NUM names might soon change.)
10528 * numbers.h: Added missing declarations.
10530 2001-09-22 Mikael Djurfeldt <mdj@linnaeus>
10532 * Makefile.am: Distribute num2float.i.c.
10534 * num2float.i.c: New file, multiply included by numbers.c, used
10535 to "templatize" the float <-> num conversion routines.
10537 * numbers.c: New functions: scm_num2float, scm_float2num,
10538 scm_num2double, scm_double2num.
10540 2001-09-21 Rob Browning <rlb@defaultvalue.org>
10542 * .cvsignore: really add version.h
10544 * strings.h (SCM_SET_STRING_LENGTH): coerce "l" to a long.
10545 Otherwise it fails on the alpha. However, we might rather choose
10546 this size conditionally.
10548 * numbers.c (scm_gcd): change "k" to a long from an int.
10549 Otherwise it fails on the alpha. However, we might rather choose
10550 this size conditionally.
10552 * error.c (scm_wta): coerce char* to intptr_t before int
10555 * debug.c (debugobj_print): coerce scm_intprint arg 1 to long, not
10558 * chars.h (SCM_MAKE_CHAR): coerce value to intptr_t.
10560 2001-09-20 Mikael Djurfeldt <mdj@linnaeus>
10562 * numbers.c (scm_integer_expt): Accept inexact integer in second
10563 argument. (Thanks to Bill Schottstaedt.)
10565 2001-09-20 Rob Browning <rlb@defaultvalue.org>
10567 * .cvsignore: add version.h
10569 * versiondat.h.in: removed (obsolete).
10571 * version.h.in: renamed from version.h.
10572 (SCM_GUILE_MAJOR_VERSION): new public macro.
10573 (SCM_GUILE_MINOR_VERSION): new public macro.
10574 (SCM_GUILE_MICRO_VERSION): new public macro.
10576 * version.h: renamed to version.h.in.
10579 (scm_major_version): support integer *_VERSION macros.
10580 (scm_minor_version): support integer *_VERSION macros.
10581 (scm_micro_version): support integer *_VERSION macros.
10582 (scm_version): support integer *_VERSION macros.
10584 2001-09-20 Mikael Djurfeldt <mdj@linnaeus>
10586 * error.c, error.h: Made error keys globally accessible.
10587 Applications might want to test for these or use them in a direct
10590 * num2integral.i.c (NUM2INTEGRAL): Report an error when these
10591 routines are passed an inexact. This change in behavior is
10592 motivated by concordance with R5RS: It is more common that a
10593 primitive doesn't want to accept an inexact for an exact.
10595 2001-09-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
10597 The following patch partially undoes my patch from 2001-06-30,
10598 where I added the function scm_gc_mark_cell_conservatively. The
10599 function is buggy, since it breaks guile during conservative
10600 marking if a pointer on the stack points directly into the list of
10601 free cells on the heap: With conservative cell marking this will
10602 cause the whole free list to be scanned and marked - boom!
10604 * gc.c (allocated_mark, MARK, heap_segment,
10605 scm_gc_mark_cell_conservatively, scm_init_storage), gc.h
10606 (scm_gc_mark_cell_conservatively): Remove function
10607 scm_gc_mark_cell_conservatively and update the corresponding
10608 comments and uses accordingly. Thanks to Christopher Cramer for
10609 the patch. (Minor corrections by me.)
10611 2001-09-15 Gary Houston <ghouston@arglist.com>
10613 * root.h (scm_root_state): removed the continuation_stack and
10614 continuation_stack_ptr members, which have no apparent purpose.
10615 (scm_continuation_stack, scm_continuation_stack_ptr): #defines
10618 * root.c (root_mark), init.c (restart_stack, start_stack), gc
10619 (scm_igc): remove all references to contination_stack and
10620 continuation_stack_ptr, avoiding allocation of a vector and
10621 useless processing during gc.
10623 2001-09-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
10625 * guardians.c (tconc_t, t_tconc): Renamed tconc_t to t_tconc.
10627 (TCONC_IN): Make sure that the cell word 0 is initialized last.
10629 (guardians_t, t_guardians): Renamed guardians_t to t_guardians.
10631 (GUARDIAN, GUARDIAN_DATA): Renamed GUARDIAN to GUARDIAN_DATA.
10633 (guardian_apply, scm_get_one_zombie, scm_make_guardian,
10634 mark_and_zombify): Prefer !SCM_<foo> over SCM_N<foo>.
10636 2001-09-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
10638 * guardians.c (mark_dependencies_in_tconc,
10639 whine_about_self_centered_zombies, scm_init_guardians): Register
10640 the static global variable `self_centered_zombies' via
10641 scm_gc_register_root, to make some cdr-ing unnecessary.
10643 2001-09-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
10645 * backtrace.c (display_backtrace_file,
10646 display_backtrace_file_and_line): Use SCM_EQ_P when comparing SCM
10647 values, use SCM_FALSEP when comparing SCM values against #f.
10648 Thanks to Rob Browning for the bug report.
10650 2001-09-12 Martin Baulig <martin@home-of-linux.org>
10652 * strings.[ch] (scm_str2string): New function.
10654 2001-09-06 Marius Vollmer <mvo@zagadka.ping.de>
10656 * gc.c (scm_done_free): Always subtract size from scm_mallocated
10657 when computing nm, even if it's negative.
10658 (scm_must_malloc): Abort on overflow of scm_mtrigger.
10659 (scm_must_realloc): Likewise.
10661 2001-09-01 Michael Livshin <mlivshin@bigfoot.com>
10663 * numbers.c (scm_sys_check_number_conversions): new function,
10664 defined if Guile is compiled in debugging mode. currently checks
10665 `scm_num2ulong', should check much much more.
10667 * num2integral.i.c (NUM2INTEGRAL): when converting a bignum to
10668 unsigned, ensure that it's positive. thanks to Martin Baulig!
10670 2001-08-31 Dirk Herrmann <D.Herrmann@tu-bs.de>
10672 * __scm.h: Added new section about compile time selectable
10675 (long_long, ulong_long, scm_sizet, SCM_WNA, SCM_OUTOFRANGE,
10676 SCM_NALLOC, SCM_HUP_SIGNAL, SCM_INT_SIGNAL, SCM_FPE_SIGNAL,

10678 SCM_TICK_SIGNAL, SCM_SIG_ORD, SCM_ORD_SIG, SCM_NUM_SIGS):
10681 * deprecation.c (scm_include_deprecated_features): Simplified.
10683 * eval.c (EVALCAR, unmemocopy), eval.h (SCM_XEVALCAR): Use
10684 `SCM_IMP' instead of `!SCM_CELLP´.
10686 * eval.c (unmemocopy): Eliminate redundant SCM_CELLP tests.
10687 Extract side-effecting operations from macros.
10689 (scm_init_eval): Don't initialize *top-level-lookup-closure*,
10690 scm_top_level_lookup_closure_var and scm_system_transformer.
10692 * gc.c (CELL_P): New local definition to replace SCM_CELLP.
10694 (heap_segment): Use CELL_P instead of SCM_CELLP.
10696 * init.c (start_stack): Don't initialize
10697 scm_top_level_lookup_closure_var and scm_system_transformer.
10699 * modules.c (scm_set_current_module): Don't access
10700 scm_top_level_lookup_closure_var and scm_system_transformer.
10702 (scm_sym2var): Don't call scm_variable_set_name_hint.
10704 (scm_post_boot_init_modules): Removed deprecated initializations.
10706 * print.c (scm_ipruk): Don't access cell contents of non cells.
10708 * strings.c (scm_string_set_x): All strings are writable.
10710 * strings.h (SCM_STRINGP): Use SCM_TYP7 to determine the string
10711 type. There is only one string type now.
10713 (SCM_STRING_COERCE_0TERMINATION_X): Deprecated.
10715 * tags.h: Remove comments about two different string types.
10717 (SCM_CELLP, SCM_NCELLP): Deprecated.
10719 * variable.c (make_variable): Remove code variant for vcells.
10721 * variable.h (SCM_VARIABLE_REF, SCM_VARIABLE_SET,
10722 SCM_VARIABLE_LOC): Remove code variant for vcells.
10724 * __scm.h, deprecation.[ch]: Renamed SCM_DEBUG_DEPRECATED to
10725 SCM_ENABLE_DEPRECATED with the logic reversed.

11274 2001-07-04 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
11276 * hooks.c (scm_make_hook, scm_add_hook_x),
11277 (scm_remove_hook_x, scm_reset_hook_x, scm_run_hook): Added return
11278 value info to the docstrings.
11280 2001-07-03 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
11282 Some more compatibility patches for Windows.
11284 * posix.c (getlogin): getlogin() implementation for Windows.
11286 * backtrace.c, ioext.c: Include <stdio.h>.
11288 * unif.c, script.c, rw.c, error.c: Include <io.h>, if it does
11291 * cpp_sig_symbols.in: Added SIGBREAK.
11293 2001-07-01 Marius Vollmer <mvo@zagadka.ping.de>
11295 * strports.c (scm_read_0str, scm_eval_0str): Call
11296 scm_c_read_string and scm_c_eval_string respectively, not
11297 themselves. Thanks to Dale P. Smith!
11299 2001-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
11301 * unif.c (scm_array_set_x): The variable args does not
11302 necessarily have to be a list. Further, got rid of a redundant
11305 2001-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
11307 * list.c (SCM_I_CONS): Make sure the cell type is initialized
11310 * gc.c (s_scm_map_free_list, scm_igc, scm_gc_sweep,
11311 init_heap_seg): Fixed signedness.
11313 (init_heap_seg): Replaced strange for-loop with a while loop.
11315 * weaks.h (WEAKSH, SCM_WEAKS_H): Rename <foo>H to SCM_<foo>_H.
11317 (SCM_WVECTP): Prefer !SCM_<pred> over SCM_N<pred>.
11319 The following patch adds conservative marking for the elements of
11320 free or allocated cells.
11322 * gc.c (allocated_mark, heap_segment): New static functions.
11324 (which_seg): Deleted, since the functionality is now provided by
11325 function heap_segment.
11327 (map_free_list): Use heap_segment instead of which_seg.
11329 (MARK): If cell debugging is disabled, mark free cells
11332 (scm_mark_locations, scm_cellp): Extracted the search for the
11333 heap segment of a SCM value into function heap_segment.
11335 (scm_init_storage): Allocated cells must be marked
11338 * gc.[ch] (scm_gc_mark_cell_conservatively): New function.
11340 The following patch changes the representation of weak vectors to
11341 double cells instead of using an extension of the vector's
11344 * gc.c (MARK): Use SCM_SET_WVECT_GC_CHAIN instead of assigning to
11345 the result of SCM_WVECT_GC_CHAIN.
11347 (scm_gc_sweep): Weak vectors don't have extra fields any more.
11349 * weaks.c (allocate_weak_vector): New static function. It does
11350 not patch any previously created vector object during the
11351 construction of a weak vector, and thus doesn't need to switch
11352 off interrupts during vector creation.
11354 (scm_make_weak_vector, scm_make_weak_key_hash_table,
11355 scm_make_weak_value_hash_table, scm_make_doubly_weak_hash_table):
11356 Use allocate_weak_vector to provide the new weak vector object.
11358 * weaks.h (SCM_WVECT_TYPE, SCM_SET_WVECT_TYPE,
11359 SCM_SET_WVECT_GC_CHAIN): New macros. The weak vector subtype is
11360 now stored in the double cell.
11362 (SCM_IS_WHVEC, SCM_IS_WHVEC_V, SCM_IS_WHVEC_B, SCM_IS_WHVEC_ANY):
11363 Use SCM_WVECT_TYPE.
11365 (SCM_WVECT_GC_CHAIN): The weak objects are now chained together
11366 using an entry of the double cell.
11368 2001-06-30 Thien-Thi Nguyen <ttn@revel.glug.org>
11370 * stamp-h.in: bye bye
11372 2001-06-30 Marius Vollmer <mvo@zagadka.ping.de>
11374 * gh_eval.c (gh_eval_str): Use scm_c_eval_string instead of
11377 * load.c, load.h (scm_c_primitive_load,
11378 scm_c_primitive_load_path): New.
11380 * strports.c, strports.h (scm_c_read_string): Renamed from
11381 scm_read_0str. Also, added "const" qualifier to argument.
11382 (scm_c_eval_string): Renamed from scm_eval_0str.
11383 (scm_read_0str, scm_eval_0str): Deprecated.
11385 2001-06-28 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
11387 * fluids.c (scm_c_with_fluid): Use scm_list_1() instead of
11390 2001-06-28 Keisuke Nishida <kxn30@po.cwru.edu>
11392 * list.h (scm_list_1, scm_list_2, scm_list_3, scm_list_4, scm_list_5,
11393 scm_list_n): New functions.
11394 (SCM_LIST0, SCM_LIST1, SCM_LIST2, SCM_LIST3, SCM_LIST4, SCM_LIST5,
11395 SCM_LIST6, SCM_LIST7, SCM_LIST8, SCM_LIST9, scm_listify): Deprecated.
11396 (lots of files): Use the new functions.
11398 * goops.c (CALL_GF1, CALL_GF2, CALL_GF3, CALL_GF4): Use scm_call_N.
11400 * strings.c: #include "libguile/deprecation.h".
11402 2001-06-27 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
11404 * read.c (scm_lreadr): When reading a hash token, check for a
11405 user-defined hash procedure first, so that overriding the builtin
11406 hash characters is possible (this was needed for implementing
11407 SRFI-4's read synax `f32(...)').
11409 * num2integral.i.c: Use scm_t_signed_bits instead of scm_t_bits,
11410 because the latter is unsigned now and breaks comparisons like
11411 (n < (scm_t_signed_bits)MIN_VALUE).
11413 2001-06-26 Neil Jerram <neil@ossau.uklinux.net>
11415 * eval.h, eval.c (scm_call_4): New function.
11417 * eval.c (SCM_APPLY, SCM_CEVAL, ENTER_APPLY): Call trap handlers
11418 directly rather than dispatching to them via scm_ithrow and a lazy
11421 * eval.c (scm_evaluator_trap_table), eval.h (SCM_ENTER_FRAME_HDLR,
11422 SCM_APPLY_FRAME_HDLR, SCM_EXIT_FRAME_HDLR): Add three new options
11423 for trap handler procedures.
11425 * debug.h (SCM_RESET_DEBUG_MODE): Add checks for trap handler
11426 procedures not being #f.
11428 2001-06-27 Michael Livshin <mlivshin@bigfoot.com>
11430 * Makefile.am (c-tokenize.c): add rule to generate it.
11431 (EXTRA_DIST): add c-tokenize.lex, so it gets distributed.
11433 filter-doc-snarfage.c: remove.
11435 2001-06-26 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
11437 * ports.c (scm_output_port_p): Use result of SCM_COERCE_OUTPORT.
11439 The following set of changes makes compiling Guile under various
11440 Windows compilers easier. Compilation under GNU systems should
11441 not be affected at all.
11443 Thanks to Stefan Jahn for all necessary information, patches and
11446 * posix.c: Conditialize getpwent, getgrent, kill, getppid, getuid,
11447 getpgrp, ttyname, primitive-fork and some header inclusion for

11464 * net_db.c: Do not declare errno under Windows.
11466 * iselect.h, inet_aton.c: Include socket library headers under
11469 * guile.c (inner_main): Under Windows, initialize socket library
11470 and initialize gdb_interface data structures.
11472 * gdb_interface.h: Under Windows, gdb_interface cannot be
11473 initialized statically. Initialize at runtime instead.
11475 * fports.c (write_all): ssize_t -> size_t.
11476 (fport_print): Conditionalize call to ttyname().
11477 (getflags): New function, compiled only under Windows.
11479 * filesys.c: Conditionalize inclusion of <pwd.h>. Conditionalize
11480 primitives chown, link, fcntl.
11481 (scm_basename, scm_dirname): Under Windows, handle \ as well as /
11484 * backtrace.c: Include <io.h> under Windows.

11520 2001-06-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
11522 * filesys.c (scm_close), ports.c (scm_close_port,

11546 scm_read_hash_extend), stime.c (scm_strftime), strings.c

11558 (scm_symbol_to_string): Fix gc problem.
11560 * strings.h (STRINGSH, SCM_STRINGS_H): Rename <foo>H to
11563 * validate.h (SCM_VALIDATE_SUBSTRING_SPEC_COPY): Eliminate
11564 warning about comparing signed and unsigned values. This fix is
11565 not optimal, since it won't work reliably if sizeof (c_start) >
11566 sizeof (size_t) or sizeof (c_end) > sizeof (size_t). A better
11567 solution is to define this macro as an inline function, thus
11568 allowing to specifiy the types of c_start and c_end.

11624 they aren't defined already.
11626 2001-06-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
11628 * backtrace.c (display_backtrace_body): Use SCM_VALIDATE_STACK
11629 and SCM_VALIDATE_OPOUTPORT instead of SCM_ASSERT. Fix signedness
11632 * backtrace.c (display_expression, scm_set_print_params_x,

11650 called recursively.
11652 2001-06-20 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
11654 * init.c (scm_init_guile_1): Removed initialization of tag.c.
11656 * gdbint.c, init.c: Removed inclusion of tag.h.
11658 * tag.h, tag.c: Removed files.
11660 * Makefile.am: Removed tag.{h,c,doc,x} in various places.
11662 2001-06-20 Gary Houston <ghouston@arglist.com>
11664 * deprecation.c, extensions.c, rw.c: include string.h.
11666 2001-06-19 Gary Houston <ghouston@arglist.com>
11668 * filter-doc-snarfage.c (process): added ungetc in
11669 MULTILINE_COOKIE case since otherwise it fails when there's no
11670 space between the '(' and the quote of the following string
11673 2001-06-14 Marius Vollmer <mvo@zagadka.ping.de>
11675 Throughout: replace "scm_*_t" with "scm_t_*", except "scm_lisp_t".

11698 Thanks to Golubev I. N.
11700 2001-06-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
11702 * struct.h (SCM_STRUCT_VTABLE_FLAGS): New macro.
11704 * goops.h (SCM_NUMBER_OF_SLOTS): Removed bogus `\' at the end of

12108 Changed use of scm_array->scm_array_t and
12109 scm_array_dim->scm_array_dim_t to enable build with
12110 --disable-deprecated.
12112 2001-05-24 Michael Livshin <mlivshin@bigfoot.com>
12114 The purpose of this set of changes is to regularize Guile's usage
12115 of ANSI C integral types, with the following ideas in mind:
12117 - SCM does not nesessarily have to be long.
12118 - long is not nesessarily enough to store pointers.
12119 - long is not nesessarily the same size as int.
12121 The changes are incomplete and possibly buggy. Please test on

13280 (scm_string_fill_x): Removed `(r5rs)' from docstrings.
13282 2001-04-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
13284 * gc.c (MARK): Re-introduce a cheap sanity test for non debug
13285 mode, as suggested by Michael Livshin.
13287 2001-03-31 Michael Livshin <mlivshin@bigfoot.com>
13289 * backtrace.c (display_backtrace_body): since the `print_state'
13290 variable is not used (instead its data field is used directly as
13291 `pstate'), protect it from the hungry compiler optimizations.
13292 thanks to Bill Schottstaedt for the report.
13294 2001-03-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
13296 * gc.[ch] (scm_tc16_allocated): New type tag for allocated cells.
13297 It is only defined and used if guile is compiled with
13298 SCM_DEBUG_CELL_ACCESSES set to true. It's purpose is, to never
13299 let cells with a free_cell type tag be visible outside of the
13300 garbage collector when in debug mode.
13302 * gc.c (scm_debug_cell_accesses_p): Set to true as default.
13304 (scm_assert_cell_valid): Use a local static variable to avoid
13307 (MARK): Only check for rogue cell pointers in debug mode. Use
13308 scm_cellp for this purpose and place all checks for rogue pointers
13309 into that function. Further, since due to conservative scanning
13310 we may encounter free cells during marking, don't use the standard
13311 cell type accessor macro to determine the cell type.
13313 (scm_cellp): Check if the cell pointer actually points into a
13316 (scm_init_gc): Initalize scm_tc16_allocated.
13318 * gc.h (GCH): Renamed to SCM_GC_H.
13320 (SCM_VALIDATE_CELL): Enclose the expression in brackets. This
13321 might be unnecessary, but I feel better this way :-)
13323 (SCM_GC_CELL_TYPE): New macro.
13325 (SCM_SETAND_CDR, SCM_SETOR_CDR): Deprecated. These are not used
13326 in guile, and it is unlikely that they will be applied to real
13329 (SCM_SET_FREE_CELL_TYPE): Removed. It was not used.
13331 (SCM_GC_SET_ALLOCATED): New macro. Only non-empty if guile is
13332 compiled with SCM_DEBUG_CELL_ACCESSES set to true.
13334 (SCM_NEWCELL, SCM_NEWCELL2): Use of SCM_GC_SET_ALLOCATED will
13335 make sure that in debug mode no free cell will ever be visible
13336 outside of the garbage collector.
13338 2001-03-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
13340 * async.c (scm_asyncs_pending): Don't use != to compare SCM

13344 scm_make_undefined_variable): Use scm_cons to create a pair.
13346 * debug.c (scm_reverse_lookup): Perform proper type checking.
13347 Remove suspicious use of SCM_SLOPPY_CONSP.
13349 * eq.c (scm_equal_p), tags.h (SCM_ECONSP): Use SCM_CONSP instead
13350 of SCM_SLOPPY_CONSP. A sane compiler should be able to perform
13351 the corresponding optimization.
13353 * eval.c (iqq): Use proper type check.
13355 (scm_m_expand_body): Remove redundant type checks.
13357 (promise_print): Don't access promise cells as pairs.
13359 * eval.c (EVALCAR, iqq, scm_m_expand_body, scm_eval_args,
13360 scm_deval_args SCM_CEVAL), guardians.c (scm_guard), hashtab.c
13361 (scm_internal_hash_fold), print.c (scm_iprlist): Use !SCM_CELLP
13362 for SCM_NCELLP, !SCM_CONSP for SCM_NCONSP, !SCM_IMP for SCM_NIMP,
13363 !SCM_FALSEP for SCM_NFALSEP, !SCM_NULLP for SCM_NNULLP
13365 * eval.c (scm_m_define, scm_macroexp, SCM_CEVAL), print.c
13366 (scm_iprin1): Use new macro predicate and accessors.
13368 * eval.h (scm_tc16_macro): Removed declaration. It is declared
13371 * eval.h (EVALH), macros.h (MACROSH), ports.h (PORTSH), procs.h
13372 (PROCSH), tags.h (TAGSH), variable.h (VARIABLEH): Renamed to
13373 SCM_EVAL_H, SCM_MACROS_H, SCM_PORTS_H, SCM_PROCS_H, SCM_TAGS_H and
13374 SCM_VARIABLE_H. Even the macros that are used to inhibit
13375 including a header file twice should be in the SCM_ namespace.
13377 * fluids.c (scm_swap_fluids, scm_swap_fluids_reverse),
13378 properties.c (scm_primitive_property_ref,
13379 scm_primitive_property_del_x): Prefer stronger predicates like
13380 SCM_NULLP or SCM_FALSEP over SCM_IMP.
13382 * gc.c (MARK): Use proper macros to access procedure-with-setter
13383 cell elements and closure cell elements.
13385 (gc_sweep_freelist_finish, scm_gc_sweep, init_heap_seg): Don't
13386 access free cells as pairs.
13388 (scm_unprotect_object): scm_hashq_get_handle returns #f if
13389 no hashtab entry is found.
13391 * gc.c (scm_gc_sweep), ports.c (scm_close_port): Use new macro
13392 SCM_CLR_PORT_OPEN_FLAG.
13394 * guardians.c (TCONC_IN), print.c (scm_free_print_state): Don't
13395 use SCM_SET_C[AD]R for uninitialized cells.
13397 * hashtab.c (scm_hash_fn_get_handle): Use SCM_VALIDATE_VECTOR.
13398 If the hashtable has no slots, return #f instead of '(). This
13399 unifies the return value with most assoc-functions.
13401 (scm_hash_fn_ref): Use proper type check.
13403 (scm_hashq_get_handle, scm_hashv_get_handle, scm_hash_get_handle):
13404 Removed references to non-existing functions from documentation.
13406 * keywords.c (scm_keyword_dash_symbol): Use proper macros to
13407 access keyword cell elements.
13409 * macros.h (SCM_MACROP, SCM_MACRO_TYPE, SCM_MACRO_CODE): New
13412 * ports.h (SCM_CLR_PORT_OPEN_FLAG): New macro.
13414 * print.c (scm_iprlist): Added comment. Improved loop
13417 * procs.h (SCM_ENV, SCM_SETENV): Don't access closure cells as
13420 * smob.c (scm_markcdr): Don't access smob cells as pairs.
13422 * tags.h (SCM_SLOPPY_CONSP, SCM_SLOPPY_NCONSP): Deprecated.
13424 * throw.c (ACTIVATEJB, DEACTIVATEJB): Don't access jump buffer
13427 * variable.c (variable_print, variable_equalp, scm_variable_ref,
13428 scm_variable_set_x): Use proper macros to access variable cell
13431 (scm_variable_bound_p): Don't use SCM_NEGATE_BOOL.
13433 * variable.h (SCM_VARVCELL): Don't access variable cells as
13436 * vectors.c (scm_vector), weaks.c (scm_weak_vector): Simplified,
13437 added FIXME comment, removed register specifier.
13439 2001-03-29 Keisuke Nishida <kxn30@po.cwru.edu>
13441 * goops.c, goops.h (scm_init_oop_goops_goopscore_module): Deprecated.

13452 (scm_string_downcase, scm_string_capitalize_x),
13453 (scm_string_capitalize): Rewrote and corrected docstrings.

13466 * eval.c: Include "libguile/values.h"

13469 (unmemocopy, scm_ceval, scm_deval): Handle new isym.
13470 * eval.h (scm_sym_at_call_with_values, scm_m_at_call_with_values):
13471 New delcarations to support above change.
13473 * eval.c (scm_primitive_eval_x, scm_primitive_eval): Fix syntax
13474 errors with last change.

13682 * macros.h (SCM_ASSYNT): On assertion failure, issue a misc-error
13683 instead of calling scm_wta.

13708 * error.c, net_db.c, putenv.c, stime.c: Removed declaration of
13709 errno variable (can be a macro on some systems, for example when

13762 * posix.c: Added inclusion of <crypt.h>, <sys/resource.h> and
13763 <sys/file.h>, if present.
13764 (scm_init_posix): [PRIO_PROCESS, PRIO_PGRP, PRIO_USER, LOCK_SH,
13765 LOCK_EX, LOCK_UN, LOCK_NB]: New variables.

13770 2001-03-08 Neil Jerram <neil@ossau.uklinux.net>

13775 2001-03-08 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
13777 * ramap.c (racp): Removed optimization which caused array copying
13778 to fail if the two arrays shared storage. Re-inserted the IVDEP
13779 macros removed in the change of 2000-03-09. (Don't really have a
13780 complete grasp of what they are for, but they seem to be necessary
13781 on Crays. This needs testing!) Thanks to Miroslav Silovic.
13783 * hash.c (scm_string_hash): Don't downcase characters.
13785 2001-03-07 Mikael Djurfeldt <mdj@linnaeus.mit.edu>

13800 (*.doc): Add dependency on guile-snarf.awk.in.
13802 * guile-snarf.awk.in: Neglect spaces at the end of
13803 SCM_SNARF_DOCSTRING_END. Skip lines "# NN ..." in the
13804 middle of docstrings. (To avoid the problem with gcc-2.96.)

13812 (potentially) issue a scm-misc-error or wrong-num-args error

13816 about the expected type with the wrong-type-arg error message.
13818 * smob.c (scm_make_smob): Abort on misuse of smob - it indicates
13819 a C level bug that can't be fixed from scheme anyway.
13821 2001-03-05 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
13823 * eval.c (scm_m_letstar): Removed check for duplicate bindings.
13824 Duplicate bindings are OK in a let* since a let* is semantically
13825 equivalent to a nested set of let:s.
13827 2001-03-05 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
13829 * print.c (scm_print_options): Fixed texinfo in docstring.
13831 * net_db.c (scm_getserv, scm_getproto, scm_getnet): Return #f if
13832 the underlying functions getservent, getprotoent or getnetent
13833 return NULL instead of signalling an error.
13835 2001-03-04 Gary Houston <ghouston@arglist.com>
13837 * socket.c (scm_fill_sockaddr): don't allow buffer overflows when
13838 taking an unexpectedly large filename for an AF_UNIX socket from

13841 * socket.c (scm_sock_fd_to_port, SCM_SOCK_FD_TO_PORT): removed the
13842 former and adjusted the latter.
13843 (scm_socket, scm_socketpair): cosmetic changes.
13844 (scm_getsockopt, scm_setsockopt): declare optlen as int, not
13845 size_t as socklen_t substitute. don't restrict args/return values
13846 to INUM: allow full range of int or size_t.
13847 (scm_fill_sockaddr): check arguments before allocating memory, to
13848 avoid leakage. use malloc, not scm_must_malloc.
13849 (scm_connect, scm_bind, scm_sendto): use int, not size_t as socklen_t
13850 substitute. free the sockaddr structure before throwing an error.
13851 (scm_init_add_buffer): procedure removed, together with its static
13852 buffer scm_addr_buffer, which wouldn't be thread safe. instead,
13853 define a macro MAX_ADDR_SIZE and declare the buffer where needed.
13854 (scm_accept, scm_getpeername, scm_getsockname, scm_recvfrom,
13855 scm_sendto): use a local buffer instead of scm_addr_buffer.
13856 adjust for new SCM_SOCK_FD_TO_PORT. use int for address size,
13858 (scm_recvfrom): set addr->sa_family to AF_UNSPEC before the recvfrom
13859 call to detect whether recvfrom could be bothered to set the address.
13860 (scm_init_socket): don't call scm_init_addr_buffer.

13873 scm_array_to_list, scm_array_prototype), validate.h
13874 (SCM_VALIDATE_NUMBER_COPY): Don't call function scm_wta, call

13909 immediate, literal constant should be evaluated.
13910 * eval.c (scm_s_duplicate_formals): New error message string.
13911 (scm_c_improper_memq): New function.
13912 (scm_m_lambda): Check for duplicate arguments.
13913 (scm_ceval, scm_deval): When executing a body: only cons a new
13914 toplevel environment frame when it is different from the
13915 existing one; use EVALCAR instead of SIDEVAL so that we can properly
13916 check for empty combinations; use SCM_EVALIM2 for the same reason
13917 in the non-toplevel loop.
13918 (nontoplevel_cdrxnoap, nontoplevel_cdrxbegin, nontoplevel_begin):
13919 New labels with the meaning of their non-"nontoplevel" partners,
13920 but they are used when it is known that the body is not evaluated at
13922 (scm_apply, scm_dapply): use SCM_EVALIM2 to get proper error
13923 reporting for empty combinations.
13925 2001-03-02 Keisuke Nishida <kxn30@po.cwru.edu>

13975 2001-02-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
13977 * __scm.h (SCM_ASSERT_TYPE): Add missing macro parameter.
13978 (Obviously nobody compiles with SCM_RECKLESS defined...)
13980 * validate.h (SCM_ASSERT_RANGE): Use the argument number.
13982 2001-02-23 Mikael Djurfeldt <mdj@linnaeus.mit.edu>

13991 scm_make_polar): Rename arguments `z1' and `z2' to `x' and `y',
13992 since use of `z' suggests that the arguments may be complex.
13994 * goops.c (scm_make), numbers.c (scm_sys_expt): Fix docstring
13997 2001-02-23 Neil Jerram <neil@ossau.uklinux.net>

14006 * load.c (load): Use scm_primitive_eval_x instead of scm_i_eval_x.
14008 * goops.c (scm_add_method, DEFVAR): Use scm_eval instead of
14010 (make_class_from_template): Do not bother to set the current
14011 module around the call to DEFVAR, scm_eval takes care of that.

14013 scm_goops_lookup_closure permanent objects.
14015 * eval.c (scm_ceval, scm_deval): When evaluating expressions on
14016 top level, create a fresh top-level environment for each
14017 expression instead of mutating the exisint frame. This is
14018 important when that frame is closed over.
14020 * numbers.c (s_scm_logior) [SCM_DIGSTOOBIG]: Also use
14021 SCM_DIGSPERLONG instead of DIGSPERLONG.
14023 2001-02-21 Marius Vollmer <mvo@zagadka.ping.de>
14025 * eval.c (scm_ceval, scm_deval): Check for wrong number of args
14026 before applying arrow procedure in `cond' and before applying
14027 receiver procedure in call-with-current-continuation.
14028 (scm_i_eval): Do not invoke scm_copy_tree in argument in SCM_XEVAL
14029 macro. The argument is expanded more than one time.
14031 * numbers.c (scm_logior) [SCM_DIGSTOOBIG]: Correctly use
14032 SCM_BIGDIG instead of BIGDIG. Thanks to Steven G. Johnson!
14034 2001-02-20 Marius Vollmer <mvo@zagadka.ping.de>
14036 * guile-doc-snarf.in, guile-func-name-check.in: Added copyright

14156 2001-02-13 Marius Vollmer <marius.vollmer@uni-dortmund.de>
14158 * gc_os_dep.c: Do not include <linux/version.h>. It makes no
14159 sense to compile for a specific kernel version. Do not include
14160 <asm/signal.h> while defining __KERNEL__. This hack should no
14161 longer be needed and caused problems.
14163 2001-02-13 Marius Vollmer <mvo@zagadka.ping.de>
14165 * eval.c (scm_ceval, scm_deval): use `SIDEVAL' instead of

14181 * eval.h (scm_primitive_eval, scm_primitive_eval_x): New
14183 (scm_i_eval, scm_i_eval_x, scm_eval, scm_eval_x): Changed argument
14184 names to better reflect their meaning.
14186 * eval.c (scm_ceval, scm_deval): Recognize when `begin' is being
14187 evaluated at top-level and synronize lookup closure before
14188 executing every subform.
14189 (scm_primitve_eval_x, scm_primitive_eval): New functions.
14190 (scm_eval_x, scm_eval): Reimplement in terms of
14191 scm_primitive_eval_x and scm_primitive_eval, respectively.
14193 2001-02-09 Marius Vollmer <mvo@zagadka.ping.de>
14195 * macros.c (scm_macro_name, scm_macro_transformer): Use

14211 * ports.c (scm_unread_char): Take an optional argument.
14213 2001-02-08 Marius Vollmer <marius.vollmer@uni-dortmund.de>
14215 * modules.h (scm_selected_module, scm_current_module): Renamed
14216 scm_selected_module to scm_current_module to synchronize Scheme
14218 (scm_select_module, scm_set_current_module): Likewise. Changed
14221 * ports.c (scm_port_for_each): Make a snapshot of the port table
14222 before iterating over it. The table might change while the user
14223 code is running. With the snapshot, the user can depend on the
14224 fact that each port that existed at the start of the iteration is
14225 encountered exactly once. (ice-9 popen) depends on this.
14227 2001-02-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
14229 * strings.h (SCM_STRING_MAX_LENGTH): New macro.
14231 * strings.c (scm_makstr, scm_take_str, scm_make_string): Added
14232 range checking for the size parameter. Thanks to Martin
14233 Grabmueller for the hint.

14236 deferring unnecessary.
14238 * vectors.c (scm_make_vector): Fixed range checking.
14240 2001-02-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
14242 * vectors.h (SCM_VECTOR_MAX_LENGTH): New macro.
14244 * vectors.c (scm_make_vector, scm_c_make_vector): Improved the
14245 checking of the size parameter for type correctness and valid
14246 range. Thanks to Rob Browning for reporting the problem. Instead
14247 of deferring interrupts, scm_remember_upto_here_1 is used.
14249 2001-02-05 Keisuke Nishida <kxn30@po.cwru.edu>
14251 * dump.c (scm_store_cell_object, scm_restore_cell_object): Removed.

14275 2001-02-03 Michael Livshin <mlivshin@bigfoot.com>
14277 * gc.c (DOUBLECELL_ALIGNED_P): new macro, a better-named analog of
14278 the deprecated SCM_DOUBLE_CELLP.
14280 * tags.h (SCM_DOUBLE_CELLP): deprecated.
14282 2001-02-02 Keisuke Nishida <kxn30@po.cwru.edu>
14284 * dump.c, dump.h: New files.

14352 2001-01-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
14354 The following patch was sent by Martin Grabmueller. It makes sure
14355 that in case of parameter errors the correct function name is
14356 shown, and that parameter types are only checked once.
14358 * strop.c (string_copy, string_upcase_x, string_downcase_x,
14359 string_capitalize_x): New functions. Each one performs the core
14360 functionality of the corresponding scm_* function.

14439 The remaining code is just a wrapper to do the parameter
14442 (scm_string_leq_p, scm_string_gr_p, scm_string_geq_p): Check the
14443 parameters and call string_less_p instead of scm_string_less_p.

14551 from Matthias Köppe:
14553 * objects.h (SCM_SET_ENTITY_SETTER): new macro. SCM_ENTITY_SETTER

14573 socket.c (scm_recvfrom): use the new macro, plus minor docstring
14575 * ioext.c (scm_read_string_x_partial): don't crash if -1 is supplied
14576 for fdes. if current input port is used, check that it's a file
14579 2001-01-06 Gary Houston <ghouston@arglist.com>

14596 (GUARDIAN_LIVE, GUARDIAN_ZOMBIES, GUARDIAN_NEXT): deleted.
14597 (add_to_live_list): takes a `guardian_t *' now, not SCM.
14598 (guardian_print): print more info.

14600 error if so. take one more optional argument `throw_p'.
14601 (scm_guard): depending on the value of `throw_p', return a boolean
14603 (scm_get_one_zombie): remove redundant property test.
14604 (guardian_t): represent the various (currently 3, I hope nothing
14605 more gets added) boolean fields as bit flags.

14614 * fports.c (fport_write): bugfix: handle short writes for
14615 unbuffered ports too. optimize the buffered case by minimizing
14616 the number of write/flush calls.
