2008-08-29 Julian Graham <joolean@gmail.com>
* threads.c (fat_mutex_lock): Resolve a deadlock caused by not
checking mutex state after calling `SCM_TICK'.
2008-08-27 Ludovic Courtès <ludo@gnu.org>
Fix builds `--without-threads'. Reported by Han-Wen Nienhuys
<hanwen@xs4all.nl>.
* scmsigs.c (scm_i_close_signal_pipe): Don't refer to
`signal_pipe' unless `SCM_USE_PTHREAD_THREADS' is true.

2008-08-25 Ludovic Courtès <ludo@gnu.org>
* Makefile.am (AM_CFLAGS): New.
(guile_CFLAGS, libguile_la_CFLAGS): Use it.
2008-08-20 Ludovic Courtès <ludo@gnu.org>
* eval.c, filesys.c, gc.c, numbers.c, stime.c, threads.c: Don't
define `_GNU_SOURCE' explicitly as it's now defined in
<config.h> thanks to `AC_USE_SYSTEM_EXTENSIONS'.
2008-08-19 Han-Wen Nienhuys <hanwen@lilypond.org>
Ludovic Courtès <ludo@gnu.org>
* goops.c (scm_init_goops_builtins, go_to_hell): Fix allocation
of `hell' by passing "hell_size * sizeof (*hell)" instead of
"hell_size" to `scm_malloc ()' and `scm_realloc ()'.
2008-08-02 Neil Jerram <neil@ossau.uklinux.net>
* numbers.c (scm_rationalize): Update docstring to match the
manual (which is more correct). Change argument "err" to "eps",
also to match the manual.
2008-07-17 Neil Jerram <neil@ossau.uklinux.net>
From Thiemo Seufer <ths@networkno.de>:
* gc_os_dep.c (CPP_WORDSZ, ALIGN_DOUBLE, DATAEND,
DYNAMIC_LOADING): Added #defines.

* gen-scmconfig.h.in (SCM_I_GSC_HAVE_STRUCT_DIRENT64): New.
* gen-scmconfig.c (main): Produce definitions of
`SCM_HAVE_STRUCT_DIRENT64' and `SCM_HAVE_READDIR64_R'.
* _scm.h (dirent_or_dirent64): Depend on
`SCM_HAVE_STRUCT_DIRENT64', for the sake of HP-UX 11.11.
(readdir_r_or_readdir64_r): Depend on `SCM_HAVE_READDIR64_R',
for HP-UX 11.11.
2008-07-05 Ludovic Courtès <ludo@gnu.org>
* strings.c (scm_c_symbol_length): New function.
* strings.h (scm_c_symbol_length): New declaration.
2008-07-04 Ludovic Courtès <ludo@gnu.org>
* posix.h (scm_i_locale_mutex): Don't declare as `SCM_INTERNAL'
since it's needed by `libguile-i18n'. Reported by Patrick
Horgan <phorgan1@gmail.com>.
* __scm.h (SCM_INTERNAL): Add `extern' so that these symbols are
not considered as "common" by GCC 4.3. Reported by Patrick
Horgan <phorgan1@gmail.com>.
2008-06-28 Ludovic Courtès <ludo@gnu.org>
* Makefile.am (INCLUDES): Renamed to...
(AM_CPPFLAGS): this, to match current Automake conventions.
Users updated.
* tags.h (SCM_UNPACK): Disable type-checking for `__DECC' and

2008-06-02 Ludovic Courtès <ludo@gnu.org>
* deprecated.c (maybe_close_port): Rename EXCEPT to EXCEPT_SET
to workaround `#define except' on Tru64. Reported by Peter
O'Gorman <pogma@thewrittenword.com>.
2008-05-31 Ludovic Courtès <ludo@gnu.org>
* __scm.h (SCM_INTERNAL): New macro.
* *.h: Use it to mark as internal `scm_i_' and `scm_init_'
functions that are not used by public macros or inline
functions.
2008-05-14 Julian Graham <joolean@gmail.com>
* threads.c (fat_mutex)[recursive]: New field.
(make_fat_mutex): Adjust initialization to reflect changes to
mutex lock level semantics.
(fat_mutex_lock, fat_mutex_unlock): Add support for unowned
mutexes and locking mutexes on behalf of other threads.
(scm_lock_mutex, scm_lock_mutex_timed): Update to reflect
signature change to fat_mutex_lock.
(scm_mutex_owner, scm_mutex_level, scm_mutex_locked_p): New /
re-enabled functions.
* threads.h (scm_mutex_owner, scm_mutex_level,
scm_mutex_locked_p): Prototypes for new functions.
2008-05-12 Neil Jerram <neil@ossau.uklinux.net>
* discouraged.c: Expand DEFFROM and DEFTO macros, to avoid
compiler warnings about excess semicolons. (Reported by Didier
Godefroy.)
2008-05-08 Neil Jerram <neil@ossau.uklinux.net>
* throw.c (scm_ithrow): For IA64 add a return statement, to
appease GCC.
* threads.h (scm_i_thread): New IA64 fields:
register_backing_store_base and pending_rbs_continuation.
* threads.c (guilify_self_1): For IA64: cap RBS base address at
the current value of scm_ia64_ar_bsp, and store the capped value
in thread state.
(SCM_MARK_BACKING_STORE): Use thread->register_backing_store_base
instead of scm_ia64_register_backing_store_base().
(scm_threads_mark_stacks): Add "&" in "&t->regs", so that the code
works both for jmp_buf defined as an array, and jmp_buf defined as
a struct.
* continuations.h (scm_t_contregs): Remove `fresh' and `ctx'
fields; these are now inside the IA64 definition of `jmp_buf'.
* continuations.c (scm_make_continuation): Simplify, by moving
some of the IA64 code inside the definition of "setjmp", and by
some obvious commonizations. For IA64 register backing store
(RBS) stack base, use thread->register_backing_store_base instead
of scm_ia64_register_backing_store_base().
(copy_stack): For IA64, store pointer to continuation being
invoked in thread state, so we can restore the continuation's RBS
stack just before the next setcontext call.
(copy_stack_and_call): Don't restore RBS stack explicitly here.
It will be restored, if appropriate, inside the longjmp call.
(scm_ia64_longjmp): New function.
* __scm.h (setjmp, longjmp, jmp_buf): For IA64, implement using
getcontext and setcontext.
2008-05-07 Ludovic Courtès <ludo@gnu.org>
* numbers.c (scm_from_complex_double): Mark as `SCM_UNUSED'.
This fixes compilation with `-Werror' on FreeBSD 6.2 (i386).
2008-05-05 Neil Jerram <neil@ossau.uklinux.net>
* c-tokenize.lex: #define YY_NO_INPUT.
2008-04-26 Ludovic Courtès <ludo@gnu.org>
* read.c (scm_read_sexp): Remove extraneous semi-colon at
end-of-line, which broke compilation with GCC 2.7. Reported by
Alain Guibert <alguibert+bts@free.fr>.
2008-04-24 Ludovic Courtès <ludo@gnu.org>
* Makefile.am (DEFAULT_INCLUDES): New. Fixes compilation on
Tru64 where our "random.h" would shadown libc's one.
(INCLUDES): Add "-I$(top_buildir)", which is normally in
`DEFAULT_INCLUDES'.
* gen-scmconfig.c: Include <libguile/gen-scmconfig.h>, not
"gen-scmconfig.h" since that file is under `$(builddir)'.
2008-04-16 Ludovic Courtès <ludo@gnu.org>
* ports.c (scm_getc, scm_putc, scm_puts): Moved...
* inline.h: ... here. Noticeably improves `read' performance.
2008-04-15 Ludovic Courtès <ludo@gnu.org>
Julian Graham <joolean@gmail.com>
* read.c (scm_keyword_postfix): New.
(scm_read_opts): Update docstring for `keywords'.
(scm_read_mixed_case_symbol): Add support for postfix keywords.
2008-04-13 Ludovic Courtès <ludo@gnu.org>
* inline.h (SCM_C_USE_EXTERN_INLINE): New macro. Use it to make
sure "extern" declarations are produced when "extern inline" is
used. Simplify macrology around inline definitions.
2008-04-10 Ludovic Courtès <ludo@gnu.org>
* inline.h (SCM_C_EXTERN_INLINE): Special-case Apple's GCC
4.0-based compiler, which doesn't support GNU inline semantics
at all in C99 mode but doesn't define `__GNUC_STDC_INLINE__'.
See http://thread.gmane.org/gmane.network.gnutls.general/1135 .
2008-04-10 Andy Wingo <wingo@pobox.com>
* struct.c (scm_struct_ref, scm_struct_set_x): "Light" structs
have no hidden words (members of the SCM_STRUCT_DATA(x) array
accessed with negative indices). In that case, determine the
number of fields from the length of the struct layout
descriptor. (Most GOOPS instances are light structs.)
* goops.c (wrap_init): Initialize 'u' slots to 0, not some random
SCM value.
* goops.c (get_slot_value, set_slot_value): In the struct
allocation case, don't poke the slots array directly -- we should
go through struct-ref/struct-set! code so that we get the
permissions and allocation ('u' versus 'p') correct.
2008-04-03 Ludovic Courtès <ludo@gnu.org>
* inline.h (SCM_C_EXTERN_INLINE): New macro, addresses the
"extern inline" semantic change in C99 mode with GCC 4.3 and
later and the warning in C99 mode with GCC 4.2. Use it in the
inline function definitions.
2008-03-24 Neil Jerram <neil@ossau.uklinux.net>
Applying patch from Julian Graham, containing minor fixes to his
thread enhancements:
* threads.c (to_timespec): Change 1000000 multiplier to
1000000000.
(unchecked_unlock_sym, allow_external_unlock_sym,
recursive_sym): Use SCM_SYMBOL.
(scm_make_mutex_with_flags): When raising unsupported option
error, report what the unsupported option was.
(fat_mutex_unlock): When raising errors, unlock m->lock first.
(fat_cond_timedwait): Removed.
(scm_timed_wait_condition_variable): Call fat_mutex_unlock
directly instead of via fat_cond_timedwait.
2008-03-10 Ludovic Courtès <ludo@gnu.org>
* eval.c, filesys.c: Enclose `alloca' blob in `#ifndef alloca',
as per Gnulib's `alloca'. This should fix compilation on
FreeBSD 6.
2008-03-09 Neil Jerram <neil@ossau.uklinux.net>
* numbers.c: Only define scm_from_complex_double if it will
actually be used.
2008-03-08 Julian Graham <joolean@gmail.com>

scm_make_mutex_with_flags, scm_lock_mutex_timed,
scm_unlock_mutex_timed, scm_mutex_p, scm_condition_variable_p): New
functions.
(thread_mark): Updated to mark new struct field `mutexes'.
(do_thread_exit): Notify threads waiting on mutexes locked by exiting
thread.
(scm_join_thread, scm_make_mutex, scm_make_recursive_mutex,
scm_mutex_lock): Reimplement in terms of their newer
counterparts.
(scm_abandoned_mutex_error_key): New symbol.
(fat_mutex)[unchecked_unlock, allow_external_unlock]: New fields.
(fat_mutex_lock): Reimplement to support timeouts and abandonment.
(fat_mutex_trylock, scm_try_mutex): Remove fat_mutex_trylock and
reimplement scm_try_mutex as a lock attempt with a timeout of zero.
(fat_mutex_unlock): Allow unlocking from other threads and unchecked
unlocking; implement in terms of condition variable wait.
(scm_timed_wait_condition_variable): Reimplement in terms of
fat_mutex_unlock.
* threads.h (scm_i_thread)[mutexes]: New field.
(scm_join_thread_timed, scm_thread_p, scm_lock_mutex_timed,
scm_unlock_mutex_timed, scm_mutex_p, scm_condition_variable_p):
Prototypes for new functions.
2008-03-06 Ludovic Courtès <ludo@gnu.org>
* eval.c (scm_eval): If MODULE_OR_STATE is not a dynamic state,
make sure it's a module. Reported by David I. Lehn.
2008-03-02 Ludovic Courtès <ludo@gnu.org>
* pairs.h (scm_is_pair): Moved declaration to `inline.h'.
* inline.h: Make sure `extern' declarations are not produced
when `inline' is supported but GCC is not used. This
fixes "mixed linkage" errors with compilers such as
DEC/Compaq/HP CC.
2008-02-27 Neil Jerram <neil@ossau.uklinux.net>
* _scm.h (errno): Remove declarations that have been there
forever, and are known to conflict on some platforms with that
provided by <errno.h>, which we include unconditionally. If
<errno.h> doesn't provide a errno declaration, what is the point
of it?
2008-02-23 Ludovic Courtès <ludo@gnu.org>
* numbers.c (scm_make_rectangular): Rename argument to
`real_part' and `imaginary_part' to work around Solaris 2.10
headers which define `imaginary' as a macro. Patch by Tim
Mooney <mooney@dogbert.cc.ndsu.NoDak.edu>.
2008-02-22 Ludovic Courtès <ludo@gnu.org>
* read.c (strncasecmp): Add declaration when
`HAVE_DECL_STRNCASECMP' is undefined. Fixes compilation on
NetBSD 1.6.
* gc.c (scm_ia64_ar_bsp)[linux]: Don't discard `const' qualifier
of OPAQUE.
2008-02-21 Ludovic Courtès <ludo@gnu.org>
Fix bug #22369.
* goops.c (scm_add_slot): Add `SCM_UNDEFINED' as last argument
to `scm_list_n ()'. Thanks to René Köcher
<shirk87@googlemail.com>.
2008-02-17 Ludovic Courtès <ludo@gnu.org>
* script.c (scm_compile_shell_switches): Update copyright year.
2008-02-16 Ludovic Courtès <ludo@gnu.org>
* gc_os_dep.c: Add NetBSD/alpha support. Patch by Greg Troxel
<gdt@ir.bbn.com>.
2008-02-12 Ludovic Courtès <ludo@gnu.org>
* guile-snarf.in (tempdir): Honor `$TMPDIR'.
2008-02-11 Neil Jerram <neil@ossau.uklinux.net>
* numbers.c (SCM_COMPLEX_VALUE): Use GUILE_I instead of _Complex_I
directly, and only if GUILE_I was defined by the configure step.
(scm_log, scm_log10, scm_exp, scm_sqrt): Use SCM_COMPLEX_VALUE
code only if SCM_COMPLEX_VALUE is defined.
2008-02-07 Ludovic Courtès <ludo@gnu.org>
Fix bug #21378.
Thanks to David Diffenbaugh <davediff@nbcs.rutgers.edu>.
* read.c (scm_read_quote): Don't use `__FUNCTION__' since it is
not supported by Sun CC on Solaris 9.
(scm_read_keyword): Likewise.
* strings.c (scm_take_locale_stringn): Remove
`SCM_C_INLINE_KEYWORD' to allow compilation with Sun CC.
2008-02-07 Julian Graham <joolean@gmail.com>
* threads.c (do_thread_exit, scm_cancel_thread,
scm_set_thread_cleanup_x, scm_thread_cleanup): Lock on thread-specific
admin mutex instead of `thread_admin_mutex'.
* threads.h (scm_i_thread)[admin_mutex]: New field.
* throw.c (make_jmpbuf): Don't enter critical section during thread
spawn -- there is a possibility of deadlock if other threads are
exiting.
2008-02-06 Neil Jerram <neil@ossau.uklinux.net>
* gc-malloc.c (scm_gc_malloc): Return NULL if requested size is 0.
(scm_gc_free): Don't call `free' if mem is NULL.
2008-02-06 Ludovic Courtès <ludo@gnu.org>
* numbers.c (scm_i_mkbig, scm_i_long2big, scm_i_ulong2big,
scm_i_clonebig, scm_i_bigcmp, scm_i_dbl2big, scm_i_dbl2num,
scm_i_normbig): Remove `SCM_C_INLINE_KEYWORD' since these are
declared as `extern' in `numbers.h'. This precluded compilation
on Solaris 9 with Sun CC (reported by David Halik
<dhalik@nbcs.rutgers.edu>).
2008-02-05 Neil Jerram <neil@ossau.uklinux.net>
* fports.c (fport_seek): Make dependent on GUILE_USE_64_CALLS.
* _scm.h: Make definition of CHOOSE_LARGEFILE depend on
GUILE_USE_64_CALLS.
2008-02-01 Neil Jerram <neil@ossau.uklinux.net>
* modules.c (the_root_module): Moved before scm_current_module.

2008-01-18 Neil Jerram <neil@ossau.uklinux.net>
* hashtab.c (scm_hash_fn_create_handle_x): If supplied assoc_fn
returns neither a pair nor #f, signal a wrong-type-arg error.
(Thanks to Gregory Marton for reporting this.)
2007-12-29 Neil Jerram <neil@ossau.uklinux.net>
* gc.c (mark_gc_async): Change "func_data" to "fn_data", to avoid
clash with AIX header file.
* hooks.c (scm_c_hook_add, scm_c_hook_remove): Same again.
* hooks.h (scm_t_c_hook_function, scm_c_hook_add,
scm_c_hook_remove): Same again.
2007-12-08 Ludovic Courtès <ludo@gnu.org>
* __scm.h (SCM_EXPECT, SCM_LIKELY, SCM_UNLIKELY): New macros.
(SCM_ASSERT, SCM_ASSERT_TYPE, SCM_ASRTGO, SCM_GASSERT0,
SCM_GASSERT1, SCM_GASSERT2, SCM_GASSERTn): Use them.
* eval.c (ASSERT_SYNTAX, ASSERT_SYNTAX_2): Likewise.

errors, wrong number of arguments and similar.
* numbers.c (scm_sum): Use `SCM_LIKELY' for the sum of two
immediate numbers.
(scm_difference, scm_product, scm_i_divide): Likewise.

(scm_c_write): Validate PORT as an open output port.
* socket.c (scm_accept): Leave guile mode using
`scm_std_select ()' before calling `accept(2)'. Reported by
dskr <dskr@mac.com>.
2007-10-27 Ludovic Courtès <ludo@gnu.org>
* fports.c (scm_i_evict_port): Expect a port, rather than a pair
containing the port. Fixes a bug in the new port table (2007-08-26).
(scm_evict_ports): Use `scm_c_port_for_each ()'.
2007-10-21 Neil Jerram <neil@ossau.uklinux.net>
* eval.c (unmemoize_delay): Extend the environment before
unmemoizing the promise thunk. This fixes a segmentation fault
reported by Frank Schwidom.
2007-10-20 Julian Graham <joolean@gmail.com>
Add support for thread cancellation and user-defined thread
cleanup handlers. Small rework by Ludovic Courtès.
* null-threads.h (scm_i_pthread_cancel,
scm_i_pthread_cleanup_push, scm_i_pthread_cleanup_pop): New.
* pthread-threads.h (scm_i_pthread_cancel,
scm_i_pthread_cleanup_push, scm_i_pthread_cleanup_pop): New.
* scmsigs.c (scm_i_signal_delivery_thread,
signal_delivery_thread_mutex): New.
(signal_delivery_thread): Leave when `read_without_guile ()'
returns zero.
(start_signal_delivery_thread): Acquire SIGNAL_DELIVERY_THREAD
before spawning the thread. Initialize
SCM_I_SIGNAL_DELIVERY_THREAD.
(ensure_signal_delivery_thread): Renamed to...
(scm_i_ensure_signal_delivery_thread): this.
(scm_i_close_signal_pipe): New.
* scmsigs.h: Updated.

(guilify_self_1): Initialize `t->cleanup_handler' and
`t->canceled'.
(do_thread_exit): Invoke `t->cleanup_handler'.
(on_thread_exit): Call `scm_i_ensure_signal_delivery_thread ()'.
Call `scm_i_close_signal_pipe ()' when the next-to-last thread
vanishes.
(scm_leave_guile_cleanup): New.
(scm_i_with_guile_and_parent): Use `scm_i_pthread_cleanup_push ()'
and `scm_leave_guile_cleanup ()' to leave guile mode, rather
than call `scm_leave_guile ()' after FUNC.
(scm_cancel_thread, scm_set_thread_cleanup_x,
scm_threads_cleanup): New.
(scm_all_threads): Remove SCM_I_SIGNAL_DELIVERY_THREAD from the
returned list.

fields.
Add declarations of new functions.
2007-10-17 Ludovic Courtès <ludo@gnu.org>
* read.c (CHAR_IS_BLANK_): Add `\r' (ASCII 0x0d). This fixes a
regression compared to 1.8.2. Reported by Puneet
<schemer@gmail.com>.
2007-10-10 Ludovic Courtès <ludo@gnu.org>
* pthread-threads.h (SCM_I_PTHREAD_MUTEX_INITIALIZER): Check
`SCM_NEED_BRACES_ON_PTHREAD_MUTEX_INITIALIZER'.
* gen-scmconfig.h.in
(SCM_I_GSC_NEED_BRACES_ON_PTHREAD_MUTEX_INITIALIZER): New.
* gen-scmconfig.c (main): Define
`SCM_NEED_BRACES_ON_PTHREAD_MUTEX_INITIALIZER'.
2007-10-04 Ludovic Courtès <ludo@gnu.org>
* i18n.c (scm_make_locale)[!USE_GNU_LOCALE_API]: Don't call
`leave_locale_section ()' on failure of
`enter_locale_section ()' since the mutex is not held and locale
settings are unchanged.
(scm_nl_langinfo)[!USE_GNU_LOCALE_API]: Use
`restore_locale_settings ()' instead of `leave_locale_section ()'
since the mutex is not held.
2007-10-02 Ludovic Courtès <ludo@gnu.org>
* threads.c (on_thread_exit): Don't call `scm_leave_guile ()'
since we're already in non-guile mode. Reported by Greg Toxel
for NetBSD.
2007-10-01 Ludovic Courtès <ludo@gnu.org>
* ports.c (flush_output_port): Expect directly a port instead of
a pair. Fixes a bug in the new port table (2007-08-26).
2007-09-11 Kevin Ryde <user42@zip.com.au>
* posix.c (scm_putenv): Confine the putenv("NAME=") bit to mingw, use
putenv("NAME") as the fallback everywhere else. In particular this is
needed for solaris 9. Reported by Frank Storbeck.
2007-09-03 Ludovic Courtès <ludo@gnu.org>
* read.c (flush_ws): Handle SCSH block comments.
2007-09-03 Ludovic Courtès <ludo@gnu.org>
Fix alignment issues which showed up at least on SPARC.
* socket.c (scm_t_max_sockaddr, scm_t_getsockopt_result): New.
(scm_inet_pton): Change DST to `scm_t_uint32' for correct
alignment.
(scm_getsockopt): Change OPTVAL to `scm_t_getsockopt_result' for
correct alignment.
(_scm_from_sockaddr): Change ADDRESS to `scm_t_max_sockaddr *'.
(scm_from_sockaddr): Cast ADDRESS to `scm_t_max_sockaddr *'.
(MAX_SIZE_UN, MAX_SIZE_IN6): Removed.
(scm_accept, scm_getsockname, scm_getpeername, scm_recvfrom):
Use `scm_t_max_sockaddr' instead of "char max_addr[MAX_ADDR_SIZE]".
2007-09-03 Kevin Ryde <user42@zip.com.au>
* numbers.c (scm_log): Test HAVE_CLOG as well as HAVE_COMPLEX_DOUBLE
before using clog(). It's possible for gcc to provide the "complex
double" type, but for the system not to have the complex funcs.
(scm_exp): Ditto HAVE_CEXP for cexp().
(clog, cexp, carg): Remove fallback definitions. These only
duplicated the code within scm_log and scm_exp, and the latter have to
exist for the case when there's no "complex double". So better just
fix up the conditionals selecting between the complex funcs and plain
doubles than worry about fallbacks.
2007-09-02 Ludovic Courtès <ludo@gnu.org>
* socket.c (scm_make_socket_address): Free C_ADDRESS after use.
This fixes a memory leak.
2007-08-26 Han-Wen Nienhuys <hanwen@lilypond.org>
* fports.c gc-card.c gc.c gc.h ioext.c ports.c ports.h weaks.h
gc.c: replace port table with weak hash table. This simplifies
memory management, and fixes freed cells appearing in
port-for-each output.
* init.c (cleanup_for_exit): abort cleanup if init_mutex is still
held.
2007-08-23 Ludovic Courtès <ludo@gnu.org>
* read.c (scm_read_quote): Record position and copy source
expression when asked to. Reported by Kevin.
* stime.c: Define `_REENTRANT' only if not already defined.
2007-08-21 Kevin Ryde <user42@zip.com.au>
* gc-card.c (scm_i_card_statistics): Record scm_tc7_number types as
tc16 values so big, real, complex and fraction can be distinguished.
(scm_i_tag_name): Return "number" for scm_tc7_number, not NULL. NULL
was making numbers come out as "type 23" in gc-live-object-stats.
Fix tests of the tc16 number types, they were checked under
scm_tc7_number, but the values went down the tag>=255 smob case.
Put smob case under scm_tc7_smob instead of using tag>=255, per
recommendation in comments with scm_tc7_smob to use symbolic values.
Use SCM_TC2SMOBNUM to extract scm_smobs index, instead of explicit
code. Lose some unnecessary "break" statements.
(scm_i_card_statistics): Use scm_hashq_create_handle_x and modify the
element returned, rather than two lookups scm_hashq_ref and
scm_hashq_set_x.
2007-08-17 Kevin Ryde <user42@zip.com.au>
* stime.c: Add #define _REENTRANT, to get gmtime_r() prototype on
solaris 2.6. Reported by anirkko.
2007-07-29 Ludovic Courtès <ludo@gnu.org>
* Makefile.am (INCLUDES): Added Gnulib includes.
(gnulib_library): New.
(libguile_i18n_v_@LIBGUILE_I18N_MAJOR@_la_LIBADD): Added
`$(gnulib_library)'.
(libguile_la_LIBADD): Likewise.
* posix.c: Don't define `_GNU_SOURCE' since `gl_EARLY' arranges
to define it when available.
* srfi-14.c: Likewise.
* i18n.c: Likewise. Include Gnulib's <alloca.h>
* eval.c: Include Gnulib's <alloca.h>.
* filesys.c: Likewise.
* read.c: Don't include <strings.h> and don't provide an
`strncasecmp ()' replacement; use Gnulib's <string.h> and
`strncasecmp ()' instead.
2007-07-25 Ludovic Courtès <ludo@gnu.org>
* eval.c (macroexp): When `scm_ilength (res) <= 0', return
immediately. This used to produce a circular memoized
expression, e.g., for `(set (quote x) #t)'.
2007-07-22 Ludovic Courtès <ludo@gnu.org>
Overhauled the reader, making it faster.
* gdbint.c (tok_buf, tok_buf_mark_p): Removed.
(gdb_read): Don't use a token buffer. Use `scm_read ()' instead
of `scm_lreadr ()'.
* read.c: Overhauled. No longer use a token buffer. Use a
on-stack C buffer in the common case and use Scheme strings when
larger buffers are needed.
* read.h (scm_grow_tok_buf, scm_flush_ws, scm_casei_streq,
scm_lreadr, scm_lreadrecparen): Removed.
(scm_i_input_error): Marked as `SCM_NORETURN'.
2007-07-15 Ludovic Courtès <ludo@gnu.org>
* script.c (scm_compile_shell_switches): Updated copyright year.
2007-07-11 Ludovic Courtès <ludo@gnu.org>
* goops.c (scm_sys_method_more_specific_p): Added docstring.
Make sure LEN is greater than or equal to the minimum length of
specializers of M1 and M2. This fixes a segfault later on in
`more_specificp ()' if TARGS is too small. Reported by Marco
Maggi <marco.maggi-ipsu@poste.it>.
2007-06-26 Ludovic Courtès <ludo@gnu.org>
* fluids.c (next_fluid_num): When growing ALLOCATED_FLUIDS, make
sure to free the previous array after the new one has been
installed. This leak is made visible by running
"(define l (map (lambda (i) (make-fluid)) (iota 255)))"
from the REPL within Valgrind.
2007-06-12 Ludovic Courtès <ludo@chbouib.org>
* socket.c (scm_inet_ntop): In the `AF_INET' case, declare `addr4'
as an `scm_t_uint32' rather than re-using `addr6'. This fixes a
bus error on SPARC (and possibly others) due to unaligned access.
2007-06-07 Ludovic Courtès <ludovic.courtes@laas.fr>
* posix.c (scm_ttyname): Check whether RESULT is NULL before
making a string from it (reported by Dan McMahill). Don't call
`scm_from_locale_string ()' before the mutex is released.
2007-05-26 Ludovic Courtès <ludo@chbouib.org>
* eval.c (scm_m_define): Updated comment. Changed order for value
evaluation and `scm_sym2var ()' call, which is perfectly valid per
R5RS. This reverts the change dated 2004-04-22 by Dirk Herrmann.
2007-05-05 Ludovic Courtès <ludo@chbouib.org>
Implemented lazy duplicate binding handling.
* modules.c (scm_export): Renamed to...
(scm_module_export): This. Now public.
(module_variable): Removed.
(default_duplicate_binding_procedures_var): New variable.
(default_duplicate_binding_handlers, resolve_duplicate_binding,
module_imported_variable, scm_module_local_variable,
scm_module_variable): New functions.
(scm_module_import_interface): Rewritten.
(scm_module_reverse_lookup): Exported as a Scheme function.
* modules.h (scm_module_index_duplicate_handlers,
scm_module_index_import_obarray): New macros.
(scm_module_variable, scm_module_local_variable,
scm_module_export): New declarations.
2007-04-17 Ludovic Courtès <ludovic.courtes@laas.fr>
* numbers.c: Commented out trailing `HAVE_COMPLEX_DOUBLE' after
`#endif'. Use `#ifndef HAVE_XXX' rather than `#if !HAVE_XXX'.
2007-04-09 Han-Wen Nienhuys <hanwen@lilypond.org>
* numbers.c (carg): provide carg, cexp, clog in case they are
missing.
2007-03-12 Ludovic Courtès <ludovic.courtes@laas.fr>
* i18n.c (scm_nl_langinfo): `#ifdef'd uses of `GROUPING',
`FRAC_DIGITS', etc., which are GNU extensions. Reported by
Steven Wu.
2007-03-08 Kevin Ryde <user42@zip.com.au>
* struct.c, struct.h (scm_make_vtable): New function, providing
`make-vtable'.
* stacks.c (scm_init_stacks): Use it.
2007-03-06 Kevin Ryde <user42@zip.com.au>
* struct.c (scm_make_struct): Check for R,W,O at end of layout when
allocating a tail array. If there's no such then those tail fields
are uninitialized and garbage SCMs there can cause a segv if printed
(after fetching with struct-ref).
2007-02-22 Kevin Ryde <user42@zip.com.au>
* scmsigs.c (scm_sleep): In docstring, cross refence usleep.
(scm_usleep): Update docstring per manual, cross reference sleep.
* struct.c (scm_make_struct): Move SCM_CRITICAL_SECTION_END up so that
scm_struct_init is not within that section. scm_struct_init can
thrown an error, which within a critical section results in an
abort().
2007-02-19 Neil Jerram <neil@ossau.uklinux.net>
* Makefile.am (noinst_HEADERS): Add private-options.h, so that it
is included in the distribution.
(noinst_HEADERS): And the same for eval.i.c.
2007-01-31 Ludovic Courtès <ludovic.courtes@laas.fr>
* i18n.c: Include "libguile/threads.h" and "libguile/posix.h"
unconditionally. Include <langinfo.h> and <nl_types.h> when
available.
(SCM_I18N_STRINGIFY, SCM_LOCALE_CATEGORY_MASK,
SCM_LIST_OR_INTEGER_P): New macros.
(LC_*_MASK): When `USE_GNU_LOCALE_API' is undefined, define them
as powers of two instead of `(1 << LC_*)'.
(scm_i_locale_free): New function/macro.
(scm_global_locale): New global variable.
(smob_locale_free): Use `scm_i_locale_free ()'.
(smob_locale_mark): Check whether the SMOB is `%global-locale'.
(get_current_locale_settings): Return `EINVAL' instead of `errno'
when `setlocale' fails.
(restore_locale_settings): Likewise.
(install_locale_categories): Likewise.
(install_locale): Likewise. Stop the locale stack traversal when
all categories have been handled.
(get_current_locale, category_to_category_mask,
category_list_to_category_mask): New function.
(scm_make_locale): Use them. Accept both lists of `LC_*' values
and single `LC_*' values as the first argument. Handle the case
where BASE_LOCALE is `%global-locale'. When `USE_GNU_LOCALE_API',
duplicate C_BASE_LOCALE before using it.
(scm_nl_langinfo, define_langinfo_items): New functions.
(scm_init_i18n): When `HAVE_NL_LANGINFO', add feature
`nl-langinfo' and invoke `define_langinfo_items ()'.
* i18n.h (scm_global_locale, scm_nl_langinfo): New declarations.
* posix.c: Include <xlocale.h> when available.
(scm_i_locale_mutex): Always define it. Statically initialized.
(scm_set_locale): Invoke `scm_i_to_lc_category ()' before
acquiring the locale mutex.
(scm_init_posix): No longer initialize SCM_I_LOCALE_MUTEX here.
2007-01-27 Kevin Ryde <user42@zip.com.au>
* ports.c (scm_port_line, scm_set_port_line_x), read.c
(scm_i_input_error, scm_lreadr, scm_lreadrecparen): Corrections to
port line number type, should be "long" not "int", as per line_number
field of scm_t_port. (Makes a difference only on 64-bit systems, and
only then for a linenum above 2Gig.)
2007-01-25 Han-Wen Nienhuys <hanwen@lilypond.org>
* vector.c: remove comment as per kryde's request.
2007-01-25 Kevin Ryde <user42@zip.com.au>
* sort.c (scm_stable_sort): Return empty list for input empty list, as
done in guile 1.6 and as always done by plain `sort'. Was falling
through to SCM_WRONG_TYPE_ARG. Reported by Ales Hvezda.
2007-01-22 Han-Wen Nienhuys <hanwen@lilypond.org>
* vectors.c (s_scm_vector_move_right_x): complain about naming.
* srcprop.c: regularize comments.
* eval.c: remove superfluous ifndef DEVAL.
* private-options.h: idem.
* eval.i.c: copyright nitpicking.
* eval.c: distangle. move duplicate code to eval.i.c and include
twice.
* eval.i.c: new file.
* backtrace.c, debug.c, debug.h, deprecation.c, eq.c, eval.c
eval.h, gsubr.c, init.c, macros.c, print.c, print.h, read.c,
read.h, stacks.c, symbols.c, throw.c: use private-options.h
* private-options.h: new file: contain hardcoded option
definitions.
* private-gc.h: add FSF header.
2007-01-19 Han-Wen Nienhuys <hanwen@lilypond.org>
* debug.h (SCM_RESET_DEBUG_MODE): switch to debugging if
memoize-symbol is set.
* eval.h (SCM_MEMOIZE_HDLR): add macros for memoize symbol trap.
* eval.c (CEVAL): add memoize_symbol trap.
* options.c (scm_options_try): new function. This allows error
reporting before changing options in a critical section.
* srcprop.c: use double cell for storing source-properties. Put
filename in the plist, and share between srcprops if possible.
Remove specialized storage.
* srcprop.h: remove macros without SCM_ prefix from
interface. Remove specialized storage/type definitions.
* read.c: idem.
* print.c: idem.
* eval.c: terminate option lists with 0.
* options.c: remove n (for length) from scm_option_X
functions. Detect option list length by looking for NULL name.
2007-01-19 Ludovic Courtès <ludovic.courtes@laas.fr>
* struct.c (scm_i_struct_equalp): Skip comparison if both FIELD1
is equal to S1 and FIELD2 is equal to S2. This avoids infinite
recursion when comparing `s' fields, as the REQUIRED_VTABLE_FIELDS
added by `make-vtable-vtable'. Reported by Marco Maggi.
2007-01-18 Han-Wen Nienhuys <hanwen@lilypond.org>
* throw.c (scm_ithrow): more refined error message: print symbols
too.
2007-01-16 Kevin Ryde <user42@zip.com.au>
* feature.c, feature.h (scm_set_program_arguments_scm): New function,
implementing `set-program-arguments'.
* filesys.c (scm_init_filesys): Use scm_from_int rather than
scm_from_long for O_RDONLY, O_WRONLY, O_RDWR, O_CREAT, O_EXCL,
O_NOCTTY, O_TRUNC, O_APPEND, O_NONBLOCK, O_NDELAY, O_SYNC and
O_LARGEFILE. These are all int not long, per arg to open().
(scm_init_filesys): Use scm_from_int rather than scm_from_long for
F_DUPFD, F_GETFD, F_SETFD, F_GETFL, F_SETFL, F_GETOWN, F_SETOWN, these
are all ints (per command arg to fcntl). Likewise FD_CLOEXEC which is
an int arg to fcntl.
* posix.c (scm_putenv): Correction to "len" variable, was defined only
for __MINGW32__ but used under any !HAVE_UNSETENV (such as solaris).
Move it to where it's used. Reported by Hugh Sasse.
* regex-posix.c (scm_regexp_exec): Remove SCM_CRITICAL_SECTION_START
and SCM_CRITICAL_SECTION_END, believe not needed. Their placement
meant #\nul in the input (detected by scm_to_locale_string) and a bad
flags arg (detected by scm_to_int) would throw from a critical
section, causing an abort().
* regex-posix.c (scm_init_regex_posix): Use scm_from_int for
REG_BASIC, REG_EXTENDED, REG_ICASE, REG_NEWLINE, REG_NOTBOL,
REG_NOTEOL; they're all ints not longs (per args to regcomp and
regexec).
2007-01-10 Han-Wen Nienhuys <hanwen@lilypond.org>
* throw.c (scm_ithrow): print out key symbol and string arguments
when error happens inside a critical section, and document why.
2007-01-06 Han-Wen Nienhuys <hanwen@lilypond.org>
* read.c (s_scm_read_hash_extend): document #f argument to
read-hash-extend.
2007-01-04 Kevin Ryde <user42@zip.com.au>
* deprecated.h (scm_create_hook), version.h.in (scm_major_version,
scm_minor_version, scm_micro_version, scm_effective_version,
scm_version, scm_init_version): Use SCM_API instead of just extern,
for the benefit of mingw. Reported by Cesar Strauss.
2007-01-03 Han-Wen Nienhuys <hanwen@lilypond.org>
* gc.c (s_scm_gc_stats): return an entry for total-cells-allocated
too.
(gc_update_stats): update scm_gc_cells_allocated_acc too.
2006-12-27 Kevin Ryde <user42@zip.com.au>
* threads.c (get_thread_stack_base): In mingw with pthreads we can use
the basic scm_get_stack_base. As advised by Nils Durner.
* threads.c (get_thread_stack_base): Add a version using
pthread_get_stackaddr_np (when available), for the benefit of MacOS.
As advised by Heikki Lindholm.
* scmsigs.c (signal_delivery_thread): Restrict scm_i_pthread_sigmask
to HAVE_PTHREAD_SIGMASK, it doesn't exist on mingw. Reported by Nils
Durner.
2006-12-24 Kevin Ryde <user42@zip.com.au>
* posix.c (scm_kill): When only raise() is available, throw an ENOSYS
error if pid is not our own process, instead of silently doing nothing.
* print.c (scm_write, scm_display, scm_write_char): Disable port close
on EPIPE. This was previously disabled but introduction of HAVE_PIPE
check in configure.in unintentionally enabled it. Believe that
testing errno after scm_prin1 or scm_putc is bogus, a long ago error
can leave errno in that state. popen.test "no duplicates" output test
provoked that.
2006-12-23 Han-Wen Nienhuys <hanwen@lilypond.org>
* numbers.c (scm_i_fraction_reduce): move logic into
scm_i_make_ratio(), so fractions are only read.
scm_i_fraction_reduce() modifies a fraction when reading it. A
race condition might lead to fractions being corrupted by reading
them concurrently.
Also, the REDUCED bit alters the SCM_CELL_TYPE(), making
comparisons between reduced and unreduced fractions go wrong.
* numbers.h: remove SCM_FRACTION_SET_NUMERATOR,
SCM_FRACTION_SET_DENOMINATOR, SCM_FRACTION_REDUCED_BIT,
SCM_FRACTION_REDUCED_SET, SCM_FRACTION_REDUCED_CLEAR,
SCM_FRACTION_REDUCED.
2006-12-16 Kevin Ryde <user42@zip.com.au>
* scmsigs.c (scm_raise): Use raise() rather than kill(), as this is
more direct for a procedure called raise.
(kill): Remove mingw fake fallback.
2006-12-15 Kevin Ryde <user42@zip.com.au>
* scmsigs.c: Conditionalize process.h, add io.h believe needed for
_pipe on mingw.
2006-12-14 Kevin Ryde <user42@zip.com.au>
* threads.c (thread_print): Cope with the case where pthread_t is a
struct, as found on mingw. Can't just cast to size_t for printing.
Reported by Nils Durner.
* scmsigs.c: Add <fcntl.h> and <process.h> needed by mingw. Copy the
fallback pipe() using _pipe() from posix.c. Reported by Nils Durner.
2006-12-13 Kevin Ryde <user42@zip.com.au>
* eval.c (scm_m_define): Set 'name procedure property on any
scm_procedure_p, not just SCM_CLOSUREP. In particular this picks up
procedures with setters as used in srfi-17.
* posix.c (scm_crypt): Check for NULL return from crypt(), which the
linux man page says is a possibility.
2006-12-12 Ludovic Courtès <ludovic.courtes@laas.fr>
* libguile/unif.c (read_decimal_integer): Let RESP be SIGN * RES
instead of RES (reported by Szavai Gyula). This allows the use of
negative lower bounds.
(scm_i_read_array): Make sure LEN is non-negative (reported by
Szavai Gyula).
(scm_array_in_bounds_p): Iterate over S instead of always
comparing indices with the bounds of S[0]. This fixes
`array-in-bounds?' for arrays with a rank greater than one and
with different lower bounds for each dimension.
2006-12-05 Kevin Ryde <user42@zip.com.au>
* numbers.c (scm_product): For flonum*inum and complex*inum, return
exact 0 if inum==0. Already done for inum*flonum and inum*complex,
and as per R5RS section "Exactness".
2006-12-03 Kevin Ryde <user42@zip.com.au>
* Makefile.am (.c.doc): Remove the "test -n" apparently attempting to
allow $AWK from the environment to override. It had syntax gremlins,
and the presence of a $(AWK) variable set by AC_PROG_AWK in the
Makefile stopped it having any effect. Use just $(AWK), which can be
overridden with "make AWK=xxx" in the usual way if desired.
2006-11-29 Ludovic Courtès <ludovic.courtes@laas.fr>
* libguile/vectors.c (scm_vector_to_list): Fixed list
construction: elements were not copied when INC is zero (see
"shared array" example in `vectors.test'). Reported by
Szavai Gyula.
2006-11-18 Ludovic Courtès <ludovic.courtes@laas.fr>
* Makefile.am (lib_LTLIBRARIES): Added `libguile-i18n-v-XX.la'.
(libguile_la_SOURCES): Added `gettext.c', removed `i18n.c'.
(libguile_i18n_v_XX_la_SOURCES, libguile_i18n_v_XX_la_CFLAGS,
libguile_i18n_v_XX_la_LIBADD, libguile_i18n_v_XX_la_LDFLAGS): New.
(DOT_X_FILES): Added `gettext.x'.
(DOT_DOC_FILES): Likewise.
(EXTRA_libguile_la_SOURCES): Added `locale-categories.h'.
(modinclude_HEADERS): Added `gettext.h'.
(EXTRA_DIST): Added `libgettext.h'.
* gettext.h: Renamed to...
* libgettext.h: New file.
* i18n.c: Renamed to...
* gettext.c: New file.
* i18n.h: Renamed to...
* gettext.h: New file.
* i18n.c, i18n.h, locale-categories.h: New files.
* init.c: Include "libguile/gettext.h" instead of
"libguile/i18n.h".
(scm_i_init_guile): Invoke `scm_init_gettext ()' instead of
`scm_init_i18n ()'.
* posix.c: Include "libguile/gettext.h" instead of
"libguile/i18n.h" Test `HAVE_NEWLOCALE' and `HAVE_STRCOLL_L'.
(USE_GNU_LOCALE_API): New macro.
(scm_i_locale_mutex): New variable.
(scm_setlocale): Lock and unlock it around `setlocale ()' calls.
* posix.h: Include "libguile/threads.h".
(scm_i_locale_mutex): New declaration.
2006-11-17 Neil Jerram <neil@ossau.uklinux.net>
* script.c (scm_shell_usage): Note need for subscription to bug-guile@gnu.org.
2006-11-08 Ludovic Courtès <ludovic.courtes@laas.fr>
* libguile/gc-freelist.c (scm_i_adjust_min_yield): Take two
"sweep_stats" arguments; use them instead of accessing the global
variables `scm_gc_cells_collected' and `scm_gc_cells_collected_1'.
* libguile/gc-segment.c (scm_i_sweep_some_cards): Reset SWEEP
before each iteration of the loop.
(scm_i_sweep_some_segments): Reset SWEEP at each iteration.
(scm_i_get_new_heap_segment): Take an additional argument
SWEEP_STATS. Compute MIN_CELLS as a function of it.
* libguile/gc.c (scm_gc_cells_collected,
scm_gc_cells_collected_1): Removed.
(scm_i_gc_sweep_stats, scm_i_gc_sweep_stats_1): New.
(scm_gc_cells_marked_acc, scm_gc_cells_swept_acc,
scm_gc_time_taken, scm_gc_mark_time_taken, scm_gc_times,
scm_gc_cell_yield_percentage, protected_obj_count): Made `static'.
(scm_gc_stats): Use `scm_i_gc_sweep_stats' instead of
`scm_gc_cells_(collected|swept)'.
(gc_update_stats): New.
(gc_end_stats): Use `scm_i_gc_sweep_stats' and
`scm_i_gc_sweep_stats_1' instead of the former globals.
(scm_gc_for_newcell): Invoke `gc_update_stats ()' after each
`scm_i_sweep_some_segments' call. This fixes a bug where the GC
would keep allocating new segments instead of re-using collected
cells (because `scm_gc_cells_collected' would remain zero).
* libguile/gc.h (scm_gc_cells_swept, scm_gc_cells_collected,
scm_gc_cell_yield_percentage): Removed.
* libguile/private-gc.h (scm_gc_cells_collected_1): Removed.
(scm_i_adjust_min_yield): Updated.
(scm_i_get_new_heap_segment): Updated.
2006-11-02 Neil Jerram <neil@ossau.uklinux.net>
* modules.c: Correct comment saying that low-level environments
will be used "in the next release".
* init.c: Comment out #include of environments.h.
(scm_i_init_guile): Comment out scm_environments_prehistory() and
scm_init_environments() calls.
* Makefile.am (libguile_la_SOURCES): Remove environments.c.
(DOT_X_FILES): Remove environments.x.
(DOT_DOC_FILES): Remove environments.doc.
(modinclude_HEADERS): Remove environments.h.
2006-10-25 Neil Jerram <neil@ossau.uklinux.net>
IA64 HP-UX GC patch from Hrvoje Nikšić. (Thanks!)
* threads.c (SCM_MARK_BACKING_STORE): Use scm_ia64_ar_bsp() and
scm_ia64_register_backing_store_base() instead of Linux-specific
implementations.
* gc.h (scm_ia64_register_backing_store_base, scm_ia64_ar_bsp):
New declarations.
* gc.c (__libc_ia64_register_backing_store_base): Declaration
removed.
(scm_ia64_register_backing_store_base, scm_ia64_ar_bsp): New, with
implementations for Linux and HP-UX.
* coop-pthreads.c (SCM_MARK_BACKING_STORE): Use scm_ia64_ar_bsp()
and scm_ia64_register_backing_store_base() instead of
Linux-specific implementations.
* continuations.h (__libc_ia64_register_backing_store_base):
Declaration removed.
(scm_t_contregs): New "fresh" field.
* continuations.c (ia64_getcontext): Removed.
(scm_make_continuation): Use continuation fresh field instead of
interpreting getcontext return values (which isn't portable). Use
scm_ia64_ar_bsp() and scm_ia64_register_backing_store_base()
instead of Linux-specific implementations.
(copy_stack_and_call): Use scm_ia64_register_backing_store_base()
instead of Linux-specific implementation.
* _scm.h (__ia64__): Also detect __ia64.
2006-10-03 Kevin Ryde <user42@zip.com.au>
* eval.c (SCM_APPLY): For scm_tc7_subr_2o, throw wrong-num-args on 0
arguments or 3 or more arguments. Previously 0 called proc with
SCM_UNDEFINED, and 3 or more silently used just the first 2.
2006-09-28 Kevin Ryde <user42@zip.com.au>
* fports.c, ports.c (ftruncate): Use "HAVE_CHSIZE && ! HAVE_FTRUNCATE"
for chsize fallback, instead of hard-coding mingw. Mingw in fact
supplies ftruncate itself these days.
* ports.c (fcntl.h): Can include this unconditionally, no need for
__MINGW32__.
* ports.c (truncate): Conditionalize on "HAVE_FTRUNCATE && !
HAVE_TRUNCATE" so as not to hard-code mingw. Use "const char *" and
"off_t" for parameters, per usual definition of this function, rather
than "char *" and "int". Use ftruncate instead of chsize. Check for
error on final close.
2006-09-27 Kevin Ryde <user42@zip.com.au>
* numbers.c (scm_log10): Check HAVE_CLOG10, clog10() is not available
in mingw.
* posix.c (scm_execl, scm_execlp, scm_execle): Cast "const char *
const *" for mingw to suppress warnings from gcc (which are errors
under the configure default -Werror). Reported by Nils Durner.

Reported by Claes Wallin.
2006-08-11 Neil Jerram <neil@ossau.uklinux.net>
* stacks.c (scm_last_stack_frame): Correct docstring (returns a
frame, not a stack).
2006-07-25 Kevin Ryde <user42@zip.com.au>
* threads.c (get_thread_stack_base): Restrict HAVE_PTHREAD_GETATTR_NP
on pthreads version, since pthread_getattr_np not available on solaris
and macos. Reported by Claes Wallin.
2006-07-24 Kevin Ryde <user42@zip.com.au>
* filesys.c (dirfd): Test with #ifndef rather than HAVE_DIRFD, since
it's a macro on MacOS X. Reported by Claes Wallin.
* posix.c (sethostname): Give prototype if not HAVE_DECL_SETHOSTNAME,
for the benefit of Solaris 10. Reported by Claes Wallin.
* socket.c (scm_htonl, scm_ntohl): Use scm_to_uint32 rather than

FD_ZERO() on Solaris 10. Reported by Claes Wallin.
2006-07-18 Rob Browning <rlb@defaultvalue.org>
* continuations.c: Add __attribute__ ((returns_twice)) to the
ia64_getcontext prototype so that gcc will make the right
arrangements and avoid an illegal instruction during
call-with-current-continuation.
2006-07-12 Ludovic Courtès <ludovic.courtes@laas.fr>
* numbers.c (guile_ieee_init): Use regular ANSI C casts rather
than C++-style `X_CAST ()'. Patch posted by by Mike Gran.
2006-07-08 Kevin Ryde <user42@zip.com.au>
* environments.c (core_environments_unobserve): Use if/else rather
than ?: for "SET" bits, avoiding complaints from AIX xlc compiler
about them not being rvalues. Reported by Mike Gran.
* Makefile.am (version.h): Don't use $< in an explicit rule, it's not
portable and in particular fails on OpenBSD and AIX (see autoconf
manual too). Reported by Mike Gran.
2006-06-25 Kevin Ryde <user42@zip.com.au>
* stime.c (bdtime2c): tm_gmtoff is seconds East, so take negative of
tm:gmtoff which is seconds West. Reported by Aaron VanDevender.
(bdtime2c): Test HAVE_STRUCT_TM_TM_GMTOFF for tm_gmtoff, rather than
HAVE_TM_ZONE.
(scm_strptime): Use tm_gmtoff from the strptime result when that field
exists, it's set by glibc strptime "%s".
2006-06-13 Ludovic Courtès <ludovic.courtes@laas.fr>
* eq.c: Include "struct.h", "goops.h" and "objects.h".

(scm_i_struct_equalp): New.
* struct.h (scm_i_struct_equalp): New declaration.
2006-06-06 Kevin Ryde <user42@zip.com.au>
* Makefile.am (BUILT_SOURCES): Remove guile.texi, only used by
maintainers (with doc/maint/docstring.el). Fixes parallel "make -j2"
reported by Mattias Holm.
2006-06-03 Kevin Ryde <user42@zip.com.au>
* read.c (s_vector): Conditionalize on SCM_ENABLE_ELISP, to avoid
unused variable warning when elisp disabled. Reported by Ryan
VanderBijl.
* throw.c (scm_handle_by_message): Add dummy return value to avoid
compiler warning on cygwin. Reported by Ryan VanderBijl.
* Makefile.am (EXTRA_DOT_X_FILES): Typo in dependency rule, was a
duplicate of EXTRA_DOT_DOC_FILES.
(DOT_X_FILES, EXTRA_DOT_X_FILES, DOT_DOC_FILES, EXTRA_DOT_DOC_FILES):
Add scmconfig.h to dependencies, since these all run cpp. Helps a
parallel "make -j2". Reported by Mattias Holm.
2006-05-30 Kevin Ryde <user42@zip.com.au>
* ports.c, ports.h (scm_set_port_mark, scm_set_port_free,
scm_set_port_print, scm_set_port_equalp, scm_set_port_flush,
scm_set_port_end_input, scm_set_port_close, scm_set_port_seek,
scm_set_port_truncate, scm_set_port_input_waiting): Use scm_t_bits for
port type descriptor, same as scm_make_port_type return value.
2006-05-30 Marius Vollmer <mvo@zagadka.de>
* eq.c (scm_equal_p): Use scm_array_equal_p explicitely when one
of the arguments is a array. This allows vectors to be equal to
one-dimensional arrays.
2006-05-29 Marius Vollmer <mvo@zagadka.de>
* throw.c (scm_ithrow): When looking for the jmpbuf, first test
that we have a pair before accessing its cdr. Thanks to Bill
Schottstaedt!
2006-05-28 Kevin Ryde <user42@zip.com.au>
* eval.c, filesys.c: Add malloc.h to get alloca() on mingw. Reported
by "The Senator".
2006-05-27 Marius Vollmer <mvo@zagadka.de>
* srfi-4.c, strings.c: Replace SCM_C_INLINE with
SCM_C_INLINE_KEYWORD. Thanks to Mark Gran!
2006-05-26 Kevin Ryde <user42@zip.com.au>
* fports.c (fport_input_waiting): For ioctl, check HAVE_IOCTL as well
as defined(FIONREAD), since mingw has FIONREAD but not ioctl().
Reported by "The Senator".
For select and ioctl, move fdes into those conditionals, to avoid
unused variable warning when neither of those used.
2006-05-23 Kevin Ryde <user42@zip.com.au>
* fports.c: Remove "fwrite" declaration under "! HAVE_UNISTD_H".
It's unused and will be in stdio.h anyway (if it's anywhere).
2006-05-20 Kevin Ryde <user42@zip.com.au>
* filesys.c (scm_stat2scm): Test #ifdef S_ISLNK directly, rather than
HAVE_S_ISLNK from configure (it was only a #ifdef test anyway).
* posix.c (scm_mknod): Test #ifdef S_IFLNK before using that (for
symlink). Probably can't create symlinks with mknod anyway though.
* inline.h (scm_is_pair): Add a workaround for i386 gcc 2.95 bad code
generation.
2006-05-15 Kevin Ryde <user42@zip.com.au>
* simpos.c, simpos.h (scm_primitive__exit): New function.
(scm_primitive_exit): Update docstring, no longer the best exit after
a fork.
2006-05-09 Kevin Ryde <user42@zip.com.au>
* numbers.c (scm_i_divide): For big/big wanting inexact, use mpq_get_d
rather than converting to doubles, to avoid inf or nan when the inputs
are too big for a double but the quotient does fit. This affects
conversions exact->inexact of big fractions.
* filesys.c (scm_open_fdes): Use open64.
(scm_init_filesys): Add O_LARGEFILE.
* ports.c (scm_seek): Use lseek64.

correctly aligned for a cell. Thanks to Miroslav Lichvar!
2006-04-18 Rob Browning <rlb@defaultvalue.org>
* _scm.h: Add back error if the size of off_t is unknown. The bug
was actually in guile-readline's configuration.
2006-04-18 Kevin Ryde <user42@zip.com.au>
* posix.c (scm_mkstemp): Update docstring from the manual, in
particular file mode 0600 is not guaranteed.
2006-04-17 Kevin Ryde <user42@zip.com.au>
* _scm.h (scm_to_off_t, scm_from_off_t): No error if unknown off_t
size, to help the guile-readline build where off_t is unused.
2006-04-16 Kevin Ryde <user42@zip.com.au>
* filesys.c (scm_stat2scm, scm_stat, scm_lstat): Use stat or stat64.
(scm_readdir): Use readdir64.
(scm_copy_file): Use open64 and fstat64, to cope with >2Gb files.

and ftruncate take off_t not size_t.
* _scm.h (stat_or_stat64 etc): Macros for selecting LFS64 when
available.
2006-04-06 Kevin Ryde <user42@zip.com.au>
* fports.c (scm_setvbuf): Fix for not _IOLBF, clear SCM_BUFLINE
instead of toggling it. Reported by Ludovic Courtès.
2006-03-26 Marius Vollmer <mvo@zagadka.de>
* threads.c (get_thread_stack_base): Use scm_get_stack_base
instead of accessing __libc_stack_end directly, and only do this
when pthread_attr_getstack is known not to work for the main
thread or when not using pthreads at all.
* gc_os_dep.c (scm_get_stack_base): Abort when the machine type is
unknown instead of returning NULL.
2006-03-21 Ludovic Courtès <ludovic.courtes@laas.fr>
* numbers.c (scm_i_mem2number): Renamed to
scm_c_locale_stringn_to_number.
* numbers.c, print.c, read.c: Updated callers.
* numbers.h: Update function declaration.
2006-03-11 Neil Jerram <neil@ossau.uklinux.net>
* unif.c (string_set): Don't return in a void function. (Reported
by Mike Gran.)
* srfi-4.c (scm_uniform_vector_read_x): Declare base as char*
rather than void*, so we can do pointer arithmetic on it.
(Reported by Mike Gran.)
(s_scm_uniform_vector_write): Ditto.
2006-03-10 Neil Jerram <neil@ossau.uklinux.net>
* unif.c (scm_make_shared_array): Don't use SCM_I_ARRAY_BASE when
oldra is not an array. (Reported by Steve Juranich.)
* threads.c (do_unlock): Renamed from "unlock", which is defined
in unistd.h on QNX. (Reported by Matt Kraai.)
2006-03-04 Kevin Ryde <user42@zip.com.au>
* deprecated.c (scm_i_defer_ints_etc): Show SCM_DEFER_INTS in message,
not SCM_CRITICAL_SECTION_START.

Mike Gran.
2006-02-28 Kevin Ryde <user42@zip.com.au>
* unif.c (bitvector_set): Use h->writable_elements not h->elements.
2006-02-26 Kevin Ryde <user42@zip.com.au>
* filesys.c (scm_readdir): Use fpathconf for the dirent size when
NAME_MAX is not available, which is so on Solaris 10. Report and help
by Bill Schottstaedt.
* srfi-13.c (MY_VALIDATE_SUBSTRING_SPEC_UCOPY): New macro.
(scm_string_compare, scm_string_compare_ci, scm_string_lt,
scm_string_gt, scm_string_le, scm_string_ge, scm_string_ci_lt,
scm_string_ci_gt, scm_string_ci_le, scm_string_ci_ge): In comparisons
use "unsigned char", not signed char. This ensures comparisons are
the same as `char<?' etc, and is also the same as guile 1.6 did.
Reported by Sven Hartrumpf.
2006-02-19 Mikael Djurfeldt <mdj@neurologic.cc>
* random.c: Test for SCM_HAVE_T_UINT64 instead of
SCM_HAVE_T_INT64.
(scm_i_uniform32, scm_i_uniform32, scm_i_init_rstate): Use
scm_t_uint64 and scm_t_uint32 instead of scm_t_int64 and
scm_t_int32.
2006-01-04 Ludovic Courtès <ludovic.courtes@laas.fr>
* gc-segment.c (scm_i_sweep_some_cards): Take a SWEEP_STATS
argument. Don't refer to SCM_GC_CELLS_COLLECTED and
SCM_CELLS_ALLOCATED. If SEG->FIRST_TIME, let CELLS_COLLECTED as zero.
Take into account SEG->SPAN when computing CELLS_SWEPT.
(scm_i_sweep_segment): Take one more argument, similarly.
(scm_i_sweep_all_segments): Likewise.
(scm_i_sweep_some_segments): Likewise.
(scm_i_adjust_min_yield): Change the way MIN_CELLS is computed: do not
refer to SCM_GC_CELLS_COLLECTED.
* gc-freelist.c (scm_i_adjust_min_yield): Take one more
argument, an `scm_i_sweep_statistics' object.
Change the way DELTA is collected: don't take into account
SCM_GC_CELLS_COLLECTED_1, only SWEEP_STATS.COLLECTED.
* gc-malloc.c (scm_realloc): Pass an extra argument
to `scm_i_sweep_all_segments ()'.
* gc.c (gc_start_stats): Updated accordingly.
(gc_end_stats): Take an additional SWEEP_STATS argument.
Decrement SCM_CELLS_ALLOCATED after calls to `scm_i_sweep_* ()'.
(scm_gc_for_newcell): Updated callers of `scm_i_sweep_*'.
Decrement SCM_CELLS_ALLOCATED.
(scm_i_gc): Likewise.
* private-gc.h (scm_i_sweep_*): Updated function
prototypes accordingly.
(scm_t_sweep_statistics): New type.
(scm_i_sweep_statistics_init): New macro.
(scm_i_sweep_statistics_sum): New macro
2006-02-14 Ludovic Courtès <ludovic.courtes@laas.fr>
* strings.c (scm_i_take_stringbufn): Register LEN+1 bytes instead of
LEN. Without this, too much collectable memory gets unregistered,
which results in an underflow of SCM_MALLOCATED in
`decrease_mtrigger()'.
* gc-malloc.c (decrease_mtrigger): Make sure SIZE is lower than or
equal to SCM_MALLOCATED.
2006-02-13 Marius Vollmer <mvo@zagadka.de>
* eval.c (scm_eval_body): Use scm_i_dynwind_pthread_mutex_lock
oinstead of scm_dynwind_pthread_mutex_lock so that it works when
configured --without-threads.
(SCM_APPLY, CEVAL): Likewise. Thanks to Han-Wen Nienhuys!
2006-02-12 Marius Vollmer <mvo@zagadka.de>
* unif.c (scm_dimensions_to_uniform_array): Use the prototype for
filling when the fill parameter is omitted, as documented, but
turn #\nul into 0 since s8 arrays (signified by a #\nul prototype)
can not store characters.
2006-02-09 Neil Jerram <neil@ossau.uklinux.net>
* socket.c (scm_c_make_socket_address): Pass address_size pointer
on to scm_fill_sockaddr call.
2006-02-04 Neil Jerram <neil@ossau.uklinux.net>
* throw.h (scm_c_catch, scm_c_with_throw_handler,
scm_catch_with_pre_unwind_handler, scm_with_throw_handler): New.
* throw.c (SCM_JBPREUNWIND, SCM_SETJBPREUNWIND): New.
(struct pre_unwind_data): New, replaces struct lazy_catch.
(scm_c_catch): New, replaces scm_internal_catch as the primary
catch API for C code; adds pre-unwind handler support.
(scm_internal_catch): Now just a wrapper for scm_c_catch, for back
compatibility.
(tc16_pre_unwind_data, pre_unwind_data_print,
make_pre_unwind_data, SCM_PRE_UNWIND_DATA_P): Renamed from
"lazy_catch" equivalents.
(scm_c_with_throw_handler): New, replaces scm_internal_lazy_catch

(scm_lazy_catch): Update comment to say that the handler can
return, and what happens if it does.
(toggle_pre_unwind_running): New.
(scm_ithrow): When identifying the throw target, take running
flags into account. In general, change naming of things from
"lazy_catch" to "pre_unwind". When throwing to a throw handler,
don't unwind the dynamic context first. Add dynwind framing to
manage the running flag of a throw handler. If a lazy catch or
throw handler returns, rethrow the same exception again. Add
pre-unwind support to the normal catch case (SCM_JMPBUFP).
* root.c (scm_internal_cwdr): Add NULL args to
scm_i_with_continuation_barrier call.
* dynwind.c: Change comment mentioning lazy-catch to mention
pre-unwind data and throw handler also.
* continuations.h (scm_i_with_continuation_barrier): Add
pre-unwind handler args.
* continuations.c (scm_i_with_continuation_barrier): Add
pre-unwind handler args, and pass on to scm_c_catch (changed from

2006-02-04 Kevin Ryde <user42@zip.com.au>
* gc-mark.c (scm_mark_all): Fix c99-isms "loops" and "again" variables.
2006-02-03 Kevin Ryde <user42@zip.com.au>
* list.c, list.h (scm_list): Restore this function for use from C.
It's a complete no-op but in theory might used by someone.
2006-01-30 Marius Vollmer <mvo@zagadka.de>
* eval.c (scm_eval_body): Lock source_mutex with a dynwind context
so that it gets unlocked in all cases.
(SCM_APPLY, CEVAL): Likewise.
2006-01-29 Marius Vollmer <mvo@zagadka.de>
* ramap.c: (scm_array_map_x): Don't use scm_array_p, use
scm_is_typed_array instead.
Renamed the "frames" that are related to dynamic-wind to "dynamic
contexts. Renamed all functions from scm_frame_ to scm_dynwind_.
Updated documentation.
Disabled "futures":
* futures.h, futures.c: Wrap whole contents in "#if 0"/"#endif".
* eval.c, init.c: Comment out all 'future' related things.
2006-01-28 Marius Vollmer <mvo@zagadka.de>
* inline.h, pairs.c (scm_is_pair): Moved scm_is_pair from pairs.c
to inline.h to make it inline.
2005-12-19 Ludovic Courtès <ludovic.courtes@laas.fr>
* strings.c (scm_i_take_stringbufn): New.
(scm_i_c_take_symbol): New.
(scm_take_locale_stringn): Use `scm_i_take_stringbufn ()'.
* strings.h (scm_i_c_take_symbol): New.
(scm_i_take_stringbufn): New.
* symbols.c (lookup_interned_symbol): New function.
(scm_i_c_mem2symbol): New function.
(scm_i_mem2symbol): Use `lookup_symbol ()'.
(scm_from_locale_symbol): Use `scm_i_c_mem2symbol ()'. This avoids
creating a new Scheme string.
(scm_from_locale_symboln): Likewise.
(scm_take_locale_symbol): New.
(scm_take_locale_symboln): New.
* symbols.h (scm_take_locale_symbol): New.
(scm_take_locale_symboln): New.
2006-01-18 Han-Wen Nienhuys <hanwen@xs4all.nl>
* gc-card.c ("sweep_card"): don't count scm_tc_free_cell for
free_count.
2005-11-29 Han-Wen Nienhuys <hanwen@xs4all.nl>
* regex-posix.c (s_scm_regexp_exec): list the offending pattern
upon error
2005-12-29 Neil Jerram <neil@ossau.uklinux.net>
* fluids.c (next_fluid_num): [From Ludovic Courtès:] Don't trigger
the GC when allocated_fluids_len is zero.
2005-12-14 Neil Jerram <neil@ossau.uklinux.net>
* load.c (the_reader, the_reader_fluid_num): New.
(scm_primitive_load): Support custom reader.
(scm_init_load): Init the_reader and the_reader_fluid_num; export
the_reader as `current-reader'.
* scmsigs.c (do_read_without_guile): Use the "raw_data" passed in
(rather than an uninitialized pointer on the stack).
2005-12-07 Marius Vollmer <mvo@zagadka.de>
Reported by Bruce Korb:
* init.c (invoke_main_func): Don't call exit here. Throws that
are only caught by scm_with_guile will bypass us and would cause
scm_boot_guile to return erroneously.
(scm_boot_guile): Expect scm_with_guile to return and call exit
here, passing it an appropriate exit code.
From Andy Wingo:
* script.c (scm_find_executable): Compile fix -- fgetc returns an
unsigned char cast to an int, or -1 for EOS.
2005-12-06 Marius Vollmer <mvo@zagadka.de>
* srfi-4.h, srfi-4.c, srfi-4.i.c (take_uvec): Make BASE pointer

(signal_delivery_thread): Use it instead of
scm_leave_guile/read/scm_enter_guile.
From Stephen Compall:
* eval.c (scm_m_cond): Recognize SRFI 61 cond syntax.
(CEVAL): Evaluate SRFI 61 cond clauses.
2005-12-06 Ludovic Courtès <ludovic.courtes@laas.fr>
* gc-card.c (scm_i_card_statistics): Return if BITVEC is NULL.
This was typically hit when running `gc-live-object-stats' right
after starting Guile.
2005-11-30 Kevin Ryde <user42@zip.com.au>
* srfi-13.c (scm_string_append_shared): No copying if just one
non-empty string in args.
2005-11-26 Kevin Ryde <user42@zip.com.au>
* gc-mark.c (scm_mark_all): Change C++ comment to C comment. Reported
by Ludovic Courtès.
* list.c (list): Should be "primitive" in SCM_SNARF_DOCS, not
"register".
* random.c (scm_i_copy_rstate, scm_c_make_rstate): Don't test for
scm_malloc returning NULL, it never does that.
* putenv.c (putenv): Likewise.
* socket.c (scm_fill_sockaddr): Remove SCM_C_INLINE_KEYWORD, this is
much too big to want to inline.
2005-11-17 Ludovic Courtès <ludovic.courtes@laas.fr>
* print.c (EXIT_NESTED_DATA): Before popping from the stack, reset
the value at its top. This fixes a reference leak.
(PUSH_REF): Perform `pstate->top++' after calling
`PSTATE_STACK_SET ()' in order to avoid undesired potential side
effects.
2005-11-12 Ludovic Courtès <ludovic.courtes@laas.fr>
* gc.c (scm_weak_vectors): Removed.
2005-11-12 Kevin Ryde <user42@zip.com.au>
* socket.c (scm_setsockopt): Missing @defvar in docstring. Reported
by Ludovic Courtès.
2005-11-07 Marius Vollmer <mvo@zagadka.de>
* stime.c (scm_mktime): Use scm_frame_critical_section instead of
SCM_CRITICAL_SECTION_START/END since the code inside the critical
section might exit non-locally.
2005-11-04 Neil Jerram <neil@ossau.uklinux.net>
* eval.c (sym_instead): New symbol.
(ENTER_APPLY): Remove optional use of a continuation when making
trap call.
(scm_debug_opts): Change doc for 'cheap option to make clear that
it is now obsolete.
(CEVAL, SCM_APPLY): Remove optional use of a continuation when
making trap calls, and implement substitution of eval expressions
and return values using the values that the trap call handlers
return.
* debug.h (SCM_CHEAPTRAPS_P): Removed.
2005-10-27 Ludovic Courtès <ludovic.courtes@laas.fr>
* socket.c (scm_fill_sockaddr): No need to check NULL from scm_malloc.
(scm_connect, scm_bind, scm_sendto): Accept sockaddr object.
(scm_addr_vector): Renamed to _scm_from_sockaddr, update usages.
(scm_from_sockaddr, scm_to_sockaddr, scm_make_socket_address,
scm_c_make_socket_address): New functions.
* socket.h: Add prototypes.
2005-10-24 Kevin Ryde <user42@zip.com.au>
* socket.c (scm_init_socket): Add IPPROTO_IP, IPPROTO_TCP,
IPPROTO_UDP. Remove SOL_IP, SOL_TCP, SOL_UDP. The former are in
POSIX spec examples, the latter are not available on for instance
NetBSD.
* socket.c (scm_getsockopt, scm_setsockopt): Update docstrings from
posix.texi.
* stime.c (scm_strftime): Update docstring from posix.texi.
2005-10-23 Marius Vollmer <marius.vollmer@uni-dortmund.de>
PTHREAD_RECURSIVE_MUTEX_INITIALIZER_NP is not portable enough.
* null-threads.h, pthread-threads.h
(SCM_I_PTHREAD_RECURSIVE_MUTEX_INITIALIZER): Removed.
(scm_i_pthread_mutexattr_recursive): New.
* threads.c (scm_i_pthread_mutexattr_recursive): Declare.
(scm_i_critical_section_mutex): Do not initialize statically.
(scm_threads_prehistory): Initialize
scm_i_pthread_mutexattr_recursive and scm_i_critical_section_mutex
here.
* eval.c (source_mutex): Do not initialiaze statically.
(scm_init_eval): Do it here, using
scm_i_pthread_mutexattr_recursive.
2005-09-05 Marius Vollmer <mvo@zagadka.de>
* print.h (SCM_PRINT_KEYWORD_STYLE_I, SCM_PRINT_KEYWORD_STYLE):
New.
(sym_reader): New.
(scm_print_opts): Added "quote-keywordish-symbols" option.

(CEVAL): Eval letrec initializer forms using eval_letrec_inits.
2005-08-12 Marius Vollmer <mvo@zagadka.de>
* numbers.c: Use scm_from_bool instead of SCM_BOOL. Thanks to
Peter Gavin!
2005-08-12 Kevin Ryde <user42@zip.com.au>
* srfi-13.c (scm_string_for_each_index): Correction to docstring.
2005-08-06 Kevin Ryde <user42@zip.com.au>
* srfi-13.c (scm_string_any, scm_string_every, scm_string_tabulate,
scm_string_trim, scm_string_trim_right, scm_string_trim_both,
scm_string_index, scm_string_index_right, scm_string_skip,
scm_string_skip_right, scm_string_count, scm_string_map,
scm_string_map_x, scm_string_for_each, scm_string_for_each_index,
scm_string_filter, scm_string_delete): Use scm_t_trampoline_1 for
procedures called in loops.
2005-08-02 Kevin Ryde <user42@zip.com.au>
* strports.c (st_flush): Increase buffer by 1.5x when growing, to
avoid lots of copying where previoulsy growing by only 80 bytes at a
time.
2005-08-01 Marius Vollmer <mvo@zagadka.de>
* modules.h, modules.c (scm_eval_closure_module): Removed, we
already have scm_lookup_closure_module, which does the same thing.
2005-08-01 Marius Vollmer <mvo@zagadka.de>
New marking algorithm for weak hashtables that fixes the problem
that references from the non-weak value to the associated weak
key (for example) would prevent the entry from ever being dropped.
Guardians have been changed back to their original semantics and
are no longer greedy and no longer drop cycles.
* gc-mark.c (scm_mark_all): Do not rely on hooks to run the weak
hashtable and guardian machinery but call the relevant functions
directly.
* guardians.h, guardians.c, deprecated.h,
deprecated.c (scm_destroy_guardian_x, scm_guardian_greedy_p,
scm_guardian_destroyed_p, scm_guard, scm_get_one_zombie):
Deprecated and moved into deprecated.[ch].
* guardians.h, guardians.c: Mostly rewritten.
(scm_i_init_guardians_for_gc,
scm_i_identify_inaccessible_guardeds,
scm_i_mark_inaccessible_guardeds): New.
(scm_make_guardian): Removed greedy_p argument.
* weaks.h, weaks.c (SCM_I_WVECT_TYPE, SCM_I_SET_WVECT_TYPE): New.
(SCM_I_WVECT_N_ITEMS, SCM_I_SET_WVECT_N_ITEMS): New.
(SCM_WVECTF_NOSCAN, SCM_WVECT_NOSCAN_P): Removed.
(scm_weaks_prehistory): Removed.
(scm_i_init_weak_vectors_for_gc, scm_i_mark_weak_vector,
scm_i_mark_weak_vectors_non_weaks,
scm_i_remove_weaks_from_weak_vectors, scm_i_remove_weaks): New.
(scm_weak_vector_gc_init, scm_mark_weak_vector_spines,
scm_scan_weak_vectors): Removed.
* hashtab.h (scm_i_scan_weak_hashtables): New.
* hashtab.c (make_hash_table, scm_i_rehash): Do not use
SCM_WVECTF_NOSCAN.
(hashtable_print): Use SCM_HASHTABLE_N_ITEMS instead of
t->n_items.
(scan_weak_hashtables, scm_i_scan_weak_hashtables): Renamed former
to latter. Do not scan the alists themselves, this is done by the
weak vector code now. Just update the element count.
* vectors.h (SCM_I_WVECT_TYPE, SCM_I_WVECT_EXTRA): Renamed former
to latter. The type is now only part of the cell word.
(SCM_I_SET_WVECT_TYPE, SCM_I_SET_WVECT_EXTRA): Likewise.
* init.c (scm_i_init_guile): Do not call scm_weaks_prehistory.
2005-07-18 Mikael Djurfeldt <mdj@d14n36.pdc.kth.se>
Some changes towards making it possible to run Guile on the EM64T
platform.
* gc.c (scm_gc_stats): Bugfix: Measure size of the type we are
mallocating for (unsigned long *bounds).
* hashtab.c (scm_i_rehash): Cast SCM_HASHTABLE_FLAGS (table) to
scm_t_bits before storing them in the type word.
* gc.c (tag_table_to_type_alist): Modified type of c_tag from
scm_t_bits to int.
2005-07-12 Kevin Ryde <user42@zip.com.au>
* eval.c (scm_dbg_make_iloc): Should be SCM_IFRAMEMAX and
SCM_IDISTMAX, and cast uints through scm_t_bits to make gcc happy.
* pairs.c (scm_error_pair_access): Use scm_from_locale_string rather
than scm_makfrom0str.
Reported by Ken Raeburn.
* gc-card.c (scm_dbg_gc_get_bvec): Change return from long* to
scm_t_c_bvec_long*, gcc 4 doesn't like different pointer targets when
returning SCM_GC_CARD_BVEC.
* pairs.c (scm_error_pair_access): Plain ascii ' in error message
rather than latin-1 acute accent, the latter may not print on all
terminals.
* srfi-13.c (scm_string_filter, scm_string_delete): Strip leading and
trailing deletions, so as to return a substring if those are the only
changes.
2005-07-10 Kevin Ryde <user42@zip.com.au>
* socket.c (scm_inet_pton, scm_inet_ntop): Pointer cast to scm_t_uint8
for scm ipv6 funcs, gcc 4 is picky about char* vs uchar*.
(scm_getsockopt, scm_accept, scm_getsockname, scm_getpeername,
scm_recvfrom) Use socklen_t, gcc 4 is picky about int* vs socklen_t*.
2005-07-01 Han-Wen Nienhuys <hanwen@xs4all.nl>
* gc-card.c (scm_i_card_statistics): init tag.
* gc.c (tag_table_to_type_alist): check type of tag. Should be integer.
2005-06-18 Han-Wen Nienhuys <hanwen@xs4all.nl>
* fports.c (s_scm_open_file): add the b flag for binary to the doc
string.
2005-06-25 Kevin Ryde <user42@zip.com.au>
* srfi-13.c (scm_string_filter, scm_string_delete): Partial revert
last change, use plain copy-on-write substrings, the individual
descriptions in the srfi don't mention shared storage (only the
introduction does).
* strings.c (scm_take_locale_stringn): Use realloc to make room for
null-terminator, rather than mallocing a whole new block.
(scm_take_locale_string): Use scm_take_locale_stringn len==-1.
2005-06-12 Marius Vollmer <mvo@zagadka.de>
* ramap.c (scm_array_index_map_x): First test for real arrays,
then check for generalized vectors. This ensures that the
generalized vector case need only work with zero-origin ranges.
(scm_ra_eqp, scm_ra_compare): Use the new array handle functions
to access the target array, making these functions work with all
kinds of arrays, not just bit arrays.
* gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
gh_list.c, gh_predicates.c: Deprecated everything.
* environments.c (environment_default_folder,
environment_default_observer): Do not use gh_call3, gh_call1.
2005-06-10 Han-Wen Nienhuys <hanwen@xs4all.nl>
* modules.c (s_scm_eval_closure_module): new function. Return the
module inside an eval-closure.
* gc.c (scm_init_storage): make scm_stand_in_procs a weak_key hash
table. This means that procedure properties are GC'd if the
procedure dies.
2005-06-11 Kevin Ryde <user42@zip.com.au>
* srfi-13.c (scm_string_filter, scm_string_delete): For char and
charset cases, count chars kept and build a string in a second pass,
rather than using a cons cell for every char kept. Use a shared
substring when nothing removed (such sharing is allowed by the srfi).
2005-06-09 Han-Wen Nienhuys <hanwen@xs4all.nl>
* gc.c (tag_table_to_type_alist): convert tag number to "tag %d"
string, so live object stats can be sorted with string<?.
2005-06-06 Marius Vollmer <mvo@zagadka.de>
* print.c (iprin1): When writing a string, collect all characters
that can be printed directly into one call to scm_lfwrite.
Previously, every character was output with its own call to
write(2) on unbuffered ports.
* eval.c (scm_eval_options_interface): Use
scm_frame_critical_section instead of SCM_CRITICAL_SECTION_START
and SCM_CRITICAL_SECTION_END.
* unif.c (scm_array_in_bounds_p): First test for real arrays, then
check for generalized vectors. This ensures that the generalized
vector case need only work with zero-origin ranges.
2005-06-06 Kevin Ryde <user42@zip.com.au>
* srfi-13.c (scm_string_split): Compare char/char in scan. Mixing an
unsigned int SCM_CHAR and a char string meant an 8-bit char was never
matched.
2005-06-05 Marius Vollmer <mvo@zagadka.de>
* eval.c: Added comment on how to make case 1.1 of
r5rs_pitfall.test succeed.
From Jan Nieuwenhuizen <janneke@gnu.org>. Thanks!
* hashtab.h: Bugfix: use SCM_API (WAS: extern).
* socket.c: Remove obsolete comment about socklen_t.
(s_scm_setsockopt)[!HAVE_IP_MREQ]: Do not use ip_mreq code.
* numbers.h (isnan)[__MINGW32__]: Remove.
* Makefile.am (gen_scmconfig_SOURCES): Bugfix: Add
DEFAULT_INCLUDES when cross compiling.
* threads.c (ETIMEDOUT, pipe)[__MINGW32__]: Add defines.
* stime.c (scm_strftime)[!HAVE_TM_ZONE]: Use
SCM_SIMPLE_VECTOR_REF instead of SCM_VELTS. (Changed slightly
from Jan's patch.)
2005-05-22 Marius Vollmer <mvo@zagadka.de>
* unif.c (scm_make_shared_array): Add old base to new base since
scm_array_handle_pos does not include the base.
(scm_aind): Likewise.
* ports.c (scm_putc, scm_puts): Assert that the port argument is a
output port.
2005-05-12 Neil Jerram <neil@ossau.uklinux.net>
Mac OS X compile warning fixes, reported by Richard Todd.
* unif.c (scm_i_read_array): Declare rank as ssize_t, to guarantee
that it is signed.
* strports.c (st_resize_port): Add unsigned char cast.
(scm_mkstrport): Make read/write_buf cast unsigned.
* srfi-13.c (string_titlecase_x): Add unsigned char cast.
* rdelim.c (scm_read_line): Initialize slen.
* load.c (scm_search_path): Remove weird >=1, and add
parentheses to clarify conditions.
* hash.c (scm_hasher): Add const unsigned char cast.
* gh_data.c (gh_chars2byvect): Add scm_t_int8 cast.
2005-05-11 Neil Jerram <neil@ossau.uklinux.net>
Fix C99isms reported by Ludovic Courtès:
* threads.c (s_scm_lock_mutex): Don't declare msg in middle of
code.
* gc.c (s_scm_gc_live_object_stats): Don't declare alist in middle
of code.
* gc-card.c (scm_i_card_statistics): Don't declare tag in middle
of code.
(scm_i_card_statistics): Add block for declarations of tag_as_scm
and current.
2005-05-10 Neil Jerram <neil@ossau.uklinux.net>
* scmsigs.c (signal_delivery_thread): Return a value, to avoid
compile warning reported by Werner Scheinast.
2005-04-30 Han-Wen Nienhuys <hanwen@xs4all.nl>
* list.h: remove scm_list()
* fluids.c (DYNAMIC_STATE_NEXT_LOC): new macro for use with
SCM_DEBUG_CELL_ACCESSES
(FLUID_NEXT_LOC): idem.
2005-04-30 Kevin Ryde <user42@zip.com.au>
* numbers.c (scm_divide): Correction to 1/complex and <any>/complex,
need to test abs(re)<abs(im) for choice of cases, otherwise divide by
zero when re==0 and im<0. Reported by Jean Crepeau.
2005-04-25 Kevin Ryde <user42@zip.com.au>
* ramap.c (scm_array_map_x): Allow no source args, add num args checks
to subr_1, subr_2, subr_2o and dsubr cases. No source args only has a
few sensible uses (like filling with a random number generator say),
but has been allowed in the past and so should be kept.
2005-04-23 Kevin Ryde <user42@zip.com.au>
* hashtab.c (scm_hashx_remove_x): Need to pass "closure" to
scm_hash_fn_remove_x.
* list.c (scm_cons_star): Don't modify the rest list, it belongs to
the caller when cons* is reached through apply.
* list.c (list): Use scm_list_copy, so as to produce a fresh list when
list is called using apply, under the debugging evaluator.
(scm_list): Remove.
* list.c, list.h (scm_make_list): New code, moving make-list from
boot-9.scm.
2005-04-14 Kevin Ryde <user42@zip.com.au>
* numbers.c, numbers.h (scm_oneplus, scm_oneminus): New functions,
converted from scheme code in boot-9.scm.
2005-04-11 Kevin Ryde <user42@zip.com.au>
* srfi-13.c (scm_string_concatenate, scm_string_concatenate_shared):
Validate list argument, scm_string_append and scm_string_append_shared
don't do that to their rest argument (in a normal build).
2005-04-04 Marius Vollmer <marius.vollmer@uni-dortmund.de>
* hashtab.h, hashtab.c (scm_t_hashtable): Removed 'closure' field. The
closure can not be stored since it is no longer valid at GC time.
(make_hash_table): Initialize 'hash_fn' field.
(scm_i_rehash): Only store hash_fn in hash table when closre is
NULL.
(rehash_after_gc): Only call scm_i_rehash when 'hash_fn' is
non-NULL. Always use a NULL closure.
(scm_hash_fn_create_handle_x): Also rehash when table contains too
few entries.
2005-03-29 Marius Vollmer <marius.vollmer@uni-dortmund.de>
* hashtab.h, hashtab.c (scm_hash_fx_remove_x): Removed delete_fn
argument; always use scm_delq_x. The delete_fn function works on
the handle, not the key, and it therefore makes no sense to make
it configurable. Changed all callers.
(scm_hashx_remove_x): Likewise. Also, exported to Scheme.
(scm_hash_clear): Accept plain vectors as hashtables.
(scm_delx_x): Removed.
2005-03-28 Han-Wen Nienhuys <hanwen@xs4all.nl>
* inline.h (scm_double_cell): use __asm__ iso. asm, to maintain
compatibility with gcc -std=c99.
2005-03-24 Mikael Djurfeldt <djurfeldt@nada.kth.se>
* async.h (scm_mask_ints): Removed left over reference to
scm_root.
* threads.c: Removed fprintf debug statements.
2005-03-24 Neil Jerram <neil@ossau.uklinux.net>
* debug.c (scm_make_memoized): Restore use of SCM_UNPACK.
2005-03-23 Neil Jerram <neil@ossau.uklinux.net>
* debug.c (scm_make_memoized): Remove unnecessary critical
section, and simplify by using SCM_RETURN_NEWSMOB.
2005-03-20 Mikael Djurfeldt <djurfeldt@nada.kth.se>
* strings.h (SCM_STRING_UCHARS): Added missing argument.
2005-03-18 Kevin Ryde <user42@zip.com.au>
* arbiters.c (FETCH_STORE) [generic C]: Should be
scm_i_scm_pthread_mutex_lock/unlock now. Reported by Ludovic Courtès.
2005-03-13 Kevin Ryde <user42@zip.com.au>
* numbers.c, numbers.h (scm_i_clonebig): Remove static, so can use in
srfi-60.
* numbers.c (scm_logior): Must scm_i_normbig results as per scm_logand,
because OR-ing bits into a negative can reduce the value to an inum.
* numbers.c (scm_num_eq_p): On 64-bit systems, be careful about
casting inum to double since that can lose precision.
2005-03-10 Marius Vollmer <marius.vollmer@uni-dortmund.de>
* threads.h, threads.c (scm_i_thread): Added gc_running_p field.
(guilify_self_1): Initialize it.
* gc.h, gc.c (SCM_FREECELL_P): Removed for good.
(scm_block_gc, scm_gc_heap_lock): Removed. Removed all uses.
(scm_gc_running_p): Now a macro that refers to the scm_i_thread
field.
(scm_i_sweep_mutex): Now a non-recursive mutex. GC can not happen
recursively.
(scm_igc, scm_i_gc): Renamed former to latter. Changed all uses.
Do not lock scm_i_sweep_mutex, which is now non-recursive, or set
scm_gc_running_p. Do not run the scm_after_gc_c_hook.
(scm_gc): Lock scm_i_sweep_mutex, set scm_gc_running_p and run the
scm_after_gc_c_hook here.
(scm_gc_for_new_cell): Set scm_gc_running_p here and run the
scm_after_gc_c_hook when a full GC has in fact been performed.
(scm_i_expensive_validation_check): Call scm_gc, not scm_i_gc.
* gc-segment.c (scm_i_get_new_heap_segment): Do not check
scm_gc_heap_lock.
* gc-malloc.c (scm_realloc, increase_mtrigger): Set
scm_gc_running_p while the scm_i_sweep_mutex is locked.
* inline.h (scm_cell, scm_double_cell): Do not check
scm_gc_running_p, allocation during sweeping is OK.
* gdbint.c (SCM_BEGIN_FOREIGN_BLOCK, SCM_END_FOREIGN_BLOCK): Do
not set scm_block_gc.
* init.c (scm_i_init_guile): Do not set scm_block_gc.
* deprecation.c (scm_c_issue_deprecation_warning): Use malloc
instead of scm_malloc. The latter can not be used during GC.
2005-03-09 Marius Vollmer <mvo@zagadka.de>
* script.c (scm_compile_shell_switches): Added 2005 to Copyright
years.
2005-03-09 Marius Vollmer <marius.vollmer@uni-dortmund.de>
* gc-card.c (scm_i_sweep_card): Do not increase/decrease
scm_gc_running_p. Sweeping can happen in parallel with
allocation.
* inline.h: Updated comments for current threading implementation.
* threads.h, threads.c (scm_i_frame_single_threaded): Removed.
(scm_i_thread): Removed unused signal_asyncs field.
(threads_mark): Do not mark it.
(guilify_self_1): Do not initialize it. Do initialize
continuation_root field.
(do_thread_exit): Do not remove thread from all_threads list.
(on_thread_exit): Do it here, after leaving guile mode.
(sleep_level): Removed.
(scm_i_thread_put_to_sleep): Leave thread_admin_mutex locked when
returning. Do not support recursive sleeps.
(scm_i_thread_wake_up): Expect thread_admin_mutex to be locked on
entry. Do not support recursive sleeps.
* fluids.c (ensure_state_size, ensure_all_state_sizes,
resize_all_states): Collapsed ensure_state_size and
ensure_all_state_sizes into one function named resize_all_states.
Allocate new vectors outside of single threaded region. Do only
simple things inside that region.
(scm_make_fluid, scm_make_dynamic_state): Lock fluid_admin_mutex
while adding to the global lists.
2005-03-08 Marius Vollmer <mvo@zagadka.de>
libltdl is no longer distributed. We expect it to be installed
already.
* Makefile.am (INCLUDES): Removed @LTDLINCL@.
(libguile_la_LIBADD): Removed @LIBLTDL@.
2005-03-07 Marius Vollmer <mvo@zagadka.de>
* threads.h, async.h, threads.c (SCM_CRITICAL_SECTION_START,
SCM_CRITICAL_SECTION_END): Moved here from threads.h since now
they also block/unblock execution of asyncs and call
scm_async_click which is declared in async.h but threads.h can not
include async.h since async.h already includes threads.h.
(scm_i_critical_section_level): New, for checking mistakes in the
use of the SCM_CRITICAL_SECTION_* macros.
(scm_i_critical_section_mutex): Make it a recursive mutex so that
critical sections can be nested.
* throw.c (scm_ithrow): Abort when scm_i_critical_section_level is
not zero.
* threads.h, threads.c (scm_frame_lock_mutex): New.
(scm_frame_critical_section): Take mutex as argument.
(framed_critical_section_mutex): New, used as default for above.
(scm_init_threads): Initialize it.
(scm_threads_prehistory): Do not initialize thread_admin_mutex and
scm_i_critical_section_mutex; both are initialized statically.
* continuation.c, deprecated.c, goops.c, guardians.c keywords.c,
libguile_la-arrays.loT, objprop.c, ports.c, smob.c, sort.s,
srcprop.c, stime.c, struct.c, throw.c, regex-posix.c: Include
"libguile/async.h" for SCM_CRITICAL_SECTION_START/END.
* debug.c (scm_debug_options): Replace
SCM_CRITICAL_SECTION_START/END with a frame and
scm_frame_critical_section.
* continuations.c (scm_make_continuation): No longer a critical
section.
(scm_dynthrow): Abort when scm_i_critical_section_level is
not zero.
2005-03-04 Marius Vollmer <marius.vollmer@uni-dortmund.de>
* threads.c (scm_try_mutex): Renamed argument for consistency.
* root.c (scm_call_with_dynamic_root): New docstring.
* eval.c: Define _GNU_SOURCE.
2005-03-02 Marius Vollmer <marius.vollmer@uni-dortmund.de>
Big merge from the mvo-thread-cleanup branch. The main changes
are:
- The dynamic roots functionality has been split into dynamic
states and continuations barriers. Fluids have been
reimplemented and can now be garbage collected.
- Initialization of Guile now works in a multi-thread friendly
manner. Threads can freely enter and leave guile mode.
- Blocking on mutexes or condition variables or while selecting
can now be reliably interrupted via system asyncs.
- The low-level threading interface has been removed.
- Signals are delivered via a pipe to a dedicated 'signal delivery

Haible.
(scm_flock): Update docstring from manual.
* random.c (scm_i_init_rstate): Compare w to -1 not 0xffffffffUL, now
that it's an scm_t_int32. Otherwise gcc 3.4 says it's always false on

2004-11-12 Marius Vollmer <marius.vollmer@uni-dortmund.de>
Enclosed arrays are now their own smob. This has been done to
make the code more explicit about them and to prepare for the time
when generalized vectors include arbitrary one-dimensional
arrays. (Uptonow, enclosed arrays have been recognized by their
use of an array as their storage 'vector'. When all generalized
vectors are allowed as storage, including one-dimensional arrays,
this will no longer work.)

scm_uniform_array_write): Handle enclosed arrays explicitly.

(scm_array_creator, scm_array_prototype): Handle enclosed arrays
explicitly.
(scm_init_unif): Initialize scm_tc16_enclosed_array smob.

scm_array_creator. (scm_i_get_old_prototype): Signal error when no
prototype is known.

in terms of scm_uniform_vector_read_x and
scm_uniform_vector_write, respectively. Strings and
bitvector support has been dropped.

2004-10-27 Marius Vollmer <marius.vollmer@uni-dortmund.de>
First cut at integrating uniform vectors from srfi-4 with the rest
of Guile. This change replaces scm_tc7_byvect with a s8 uniform
vector. The plan is to gradually replace one type after the other

* srfi-4.h, srfi-4.i.c (scm_take_u8vector, etc): New.
* random.c (vector_scale, vector_scale_x): Renamed former to the
latter, since it modifies its argument.
(vector_scale_x, vector_sum_squares, scm_random_normal_vector_x):
Do not use scm_universal_vector_length for non-uniform vectors.

2004-10-20 Marius Vollmer <mvo@zagadka.de>
* sort.c (quicksort): Copy pivot out of the array while
constructing the partitions; it could get overwritten otherwise.
Because of the ultimate insertion sort, this bug did not cause
quicksort to fail, it just put all the burdon on the insertion
sort and was thus very slow. Thanks to Rolan Orre for reporting
the slowness!
2004-10-19 Marius Vollmer <marius.vollmer@uni-dortmund.de>

value" insetad of an "Unbound" one for variables that are found
but still contain SCM_UNDEFINED.

(scm_search_path): Rewritten string handling part of the code in
terms of scm_to_locale_stringbuf and so that it is thread safe.

scm_error, this avoids the back and forth conversion of SUBR and
MESSAGE and also plugs a memory leak.

* backtrace.c: Replaced SCM_STRINGP with scm_is_string.
(display_header): Print FNAME when it is true, not
merely when it is a string.

so as not to depend on signedness of plain char. For byvect range
check, throw out-of-range rather than wrong-type-arg.
* unif.c (scm_uniform_vector_ref, scm_array_set_x): For byvect, force
signed byte range checks by using scm_to_schar and scm_from_schar,
don't want to depend on signedness of C char.

* arbiters.c (scm_try_arbiter): Use scm_i_misc_mutex instead of
SCM_DEFER_INTS.
(scm_release_arbiter): Use scm_i_misc_mutex so return value can be
guaranteed if multiple threads compete to unlock.
Update docstrings per doc/ref/api-scheduling.texi.
* filesys.c (scm_copy_file): Use fstat on the input fd rather than
stat on the filename, to be certain a file rename can't mean we get
info on one filesystem object but open another. This fstat usage is
similar to Emacs copy-file.
* posix.c (scm_setgroups): Enhance docstring, per doc/ref/posix.texi.
* simpos.c (scm_system_star): Change scm_from_long to scm_from_int on

leak.
2004-07-08 Marius Vollmer <marius.vollmer@uni-dortmund.de>
* numbers.c (scm_is_signed_integer, scm_is_unsigned_integer):
Rewritten using the same logic as scm_to_signed_integer and
scm_to_unsigned_integer, respectively, which is better(tm). Also,
use CHAR_BIT instead of hardcoding 8.
(LLONG_MIN, LLONG_MAX, ULLONG_MAX): Removed and used
SCM_I_LLONG_MIN etc. instead.
* numbers.h (SCM_MAKINUM, SCM_I_MAKINUM): Renamed SCM_MAKINUM to
SCM_I_MAKINUM and changed all uses.
* deprecated.h, deprecated.c (SCM_MAKINUM): Newly deprecated.
* gen-scmconfig.c (SCM_I_LLONG_MIN, SCM_I_LLONG_MAX,
SCM_I_ULLONG_MAX): Instead of hard-coding the numbers, compute
them by assuming twos-complement.
2004-07-07 Marius Vollmer <marius.vollmer@uni-dortmund.de>
* gen-scmconfig.h.in: Added all the new SCM_I_GSC_*_LIMITS that
configure now produces.
* gen-scmconfig.c: Use them to output SCM_T_INT8_MIN, etc
definitions, giving the limits of the integer types defined by
Guile. Also, output a hard coded SCM_I_LLONG_MIN, etc since
LLONG_MIN or LONG_LONG_MIN is hard to get at.
* numbers.h (scm_to_short, scm_to_ushort): It's SHRT_MIN, etc, not
SHORT_MIN.
(scm_to_size_t): Use SIZE_MAX instead of cooking our own.
(scm_to_long_long, scm_to_ulong_long, scm_to_int8, scm_to_uint8,
scm_to_int16, scm_to_uint16, scm_to_int32, scm_to_uint32,
scm_to_int64, scm_to_uint64, scm_to_intmax, scm_to_uintmax,
scm_from_long_long, scm_from_ulong_long, scm_from_int8,
scm_from_uint8, scm_from_int16, scm_from_uint16, scm_from_int32,
scm_from_uint32, scm_from_int64, scm_from_uint64, scm_from_intmax,
scm_from_uintmax): New.
2004-07-06 Marius Vollmer <marius.vollmer@uni-dortmund.de>
* tags.h (scm_is_eq): New.
* deprecated.h, boolean.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOL,
SCM_NEGATE_BOOL, SCM_BOOLP): Deprecated by moving into
"deprecated.h". Replaced all uses with scm_is_false, scm_is_true,
scm_from_bool, and scm_is_bool, respectively.
* boolean.h (scm_is_bool): Fix bug in prototype.
(scm_from_bool): The argument is "x" not "f", stupid.
* boolean.c (scm_is_bool): Fix typo.
* numbers.h, numbers.c (scm_is_integer, scm_is_signed_integer,
scm_is_unsigned_integer, scm_to_signed_integer,
scm_to_unsigned_integer, scm_to_schar, scm_to_uchar, scm_to_char,
scm_to_short, scm_to_ushort, scm_to_long, scm_to_ulong,
scm_to_size_t, scm_to_ssize_t, scm_from_schar, scm_from_uchar,
scm_from_char, scm_from_short, scm_from_ushort, scm_from_int,
scm_from_uint, scm_from_long, scm_from_ulong, scm_from_size_t,
scm_from_ssize_t, scm_is_real, scm_to_double, scm_from_double):
New.
2004-07-05 Marius Vollmer <marius.vollmer@uni-dortmund.de>
* boolean.h, boolean.c (scm_is_true, scm_is_false, scm_from_bool,
scm_to_bool): New.
2004-06-27 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
* backtrace.c (display_expression, display_frame): Call
scm_i_unmemoize_expr for unmemoizing a memoized object holding a
single memoized expression.
* debug.c (memoized_print): Don't try to unmemoize the memoized
object, since we can't know whether it holds a single expression
or a body.
(scm_mem_to_proc): Removed check for lambda expression, since it
was moot anyway. Whoever uses these functions for debugging
purposes should know what they do: Creating invalid memoized code
will cause crashes, independent of whether this check is present
or not.
(scm_proc_to_mem): Take the closure's code as it is and don't
append a SCM_IM_LAMBDA isym. To allow easier debugging, the
memoized code should not be modified.
* debug.[ch] (scm_unmemoize, scm_i_unmemoize_expr): Removed
scm_unmemoize from public use, but made scm_i_unmemoize_expr
available as a guile internal function instead. However,
scm_i_unmemoize_expr will only work on memoized objects that hold
a single memoized expression. It won't work with bodies.
* debug.c (scm_procedure_source), macros.c (macro_print), print.c
(scm_iprin1): Call scm_i_unmemocopy_body for unmemoizing a body,
i. e. a list of expressions.
* eval.c (unmemoize_exprs): Drop internal body markers from the
output during unmemoization.
* eval.[ch] (scm_unmemocopy, scm_i_unmemocopy_expr,
scm_i_unmemocopy_body): Removed scm_unmemocopy from public use,
but made scm_i_unmemocopy_expr and scm_i_unmemocopy_body available
as guile internal functions instead. scm_i_unmemoize_expr will
only work on a single memoized expression, while
scm_i_unmemocopy_body will only work on bodies.
2004-06-21 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
* eval.c (unmemoize_exprs): Handle semi-memoized code.
(scm_cons_source, scm_primitive_eval): Prefer higher level
predicate SCM_FALSEP over SCM_IMP.
2004-06-15 Rob Browning <rlb@defaultvalue.org>
* script.c (scm_shell_usage): minor phrasing change.
* gc_os_dep.c: update ifdefery for macosx.
(scm_get_stack_base): separate result initialization from
declaration to slience warnings with macosx and hp-ux using gcc
3.3. Thanks to Andreas Vögele.
2004-06-13 Han-Wen Nienhuys <hanwen@xs4all.nl>
* eval.c (unmemoize_exprs): use SCM_CONSP for the loop condition.
2004-06-06 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
* list.[ch] (scm_i_finite_list_copy): New internal function to
copy lists that are known to be finite (though not necessarily
proper).
* debug.c (scm_procedure_source): Don't have scm_unmemocopy treat
a closure's argument list like an expression of a body.
* eval.c (unmemoize_expression, unmemoize_exprs, unmemoize_and,
unmemoize_begin, unmemoize_case, unmemoize_cond, unmemoize_delay,
unmemoize_do, unmemoize_if, unmemoize_lambda, unmemoize_let,
unmemoize_letrec, unmemoize_letstar, unmemoize_or,
unmemoize_set_x, unmemoize_apply, unmemoize_atcall_cc,
unmemoize_at_call_with_values, unmemoize_future, sym_atslot_ref,
unmemoize_atslot_ref, sym_atslot_set_x, unmemoize_atslot_set_x,
unmemoize_builtin_macro): New static functions and symbols.
(scm_unmemocopy): Rewritten in terms of the above. scm_unmemocopy
now has a slightly different meaning: The memoized form that is
receives as its argument is now interpreted as a sequence of
expressions from a body.
(unmemocar, scm_unmemocar): Since the whole functionality of
unmemocar and scm_unmemocar is not needed any more, scm_unmemocar
has its old content back and is deprecated, while unmemocar has
been removed.
(SCM_BIT7): Removed.
(CEVAL): For unmemoizing a single expression, call
unmemoize_expression instead of scm_unmemocopy, which now expects
a sequence of body expressions. Eliminated unnecessary empty
environment frame when executing let* forms. Eliminated
unmemoization step from evaluator.
2004-06-02 Marius Vollmer <marius.vollmer@uni-dortmund.de>
* eval.c (scm_macroexp, macroexp): Renamed scm_macroexp to
macroexp and made static. Added new version of scm_macroexp that
emits a deprecation warning and then calls macroexp.
(scm_m_undefine): Issue deprecation warning.
2004-05-30 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
* eval.c (lookup_global_symbol, literal_p, try_macro_lookup):
Modified to make set! work on symbols that represent syntactic
keywords.
2004-05-26 Han-Wen Nienhuys <hanwen@xs4all.nl>
* gc.h (SCM_CELL_OBJECT_LOC): use SCM_GC_CELL_OBJECT to prevent
compound expression as lvalue errors.
2004-05-24 Marius Vollmer <mvo@zagadka.de>
* dynwind.c (winder_mark): Use SCM_PACK to correctly convert the
WINDER_DATA to a SCM.
2004-05-24 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
* goops.c (compute_getters_n_setters, create_standard_classes,
scm_add_slot): Compute closures by calling scm_i_eval_x on a
lambda expression rather than creating them with scm_closure.
2004-05-22 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
* eval.c (s_macro_keyword, scm_m_set_x): Remove checking for
misplaced syntactic keywords. This will not work unless guile's
defmacro feature is deprecated.
(scm_m_case): Fixed a bug that caused the list of labels to grow
with every case form.
2004-05-19 Kevin Ryde <user42@zip.com.au>
* numbers.c (scm_round_number): For inum and big, just return x. For
real, use scm_round for 2^54-1 etc problems covered there.
* numbers.c (trunc): Remove #define to scm_truncate when the C library
doesn't provide trunc. This was for when `truncate' was done as a
scm_tc7_dsubr, no longer required.
* threads.c (scm_threads_mark_stacks) [SCM_STACK_GROWS_UP]: Correction
to stack marking call, two parameters and no cast on t->base.
2004-05-18 Marius Vollmer <mvo@zagadka.de>
* hashtab.c (rehash_after_gc): Bug fix: properly link the
processed hashtables back into the weak_hashtables list. Thanks
to Bill Schottstaedt!
2004-05-16 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
* eval.c (unmemoize_quote): New static function.
(scm_m_quote, scm_m_atslot_ref, SCM_CEVAL): Changed the byte code
representation of 'quote' and '@slot-ref' to an improper list.
This reduces execution time, the number of cells used to hold the
memoized code, and thus also reduces garbage collection time.
(scm_unmemocopy): Use unmemoize_quote for quote expressions.
(SCM_CEVAL): Changed macro handling to also work with macros that
return improper lists. Added an assertion, that the code returned
by a macro transformer will not lead to cycles in the memoized
code.
2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
No functional change, just rearrangements of functions within the
file.
* eval.c (scm_ilookup, scm_unbound_variable_key,
error_unbound_variable, scm_lookupcar1, scm_lookupcar): Moved to
the definitions used for execution, since that's where they will
belong to later.
2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
* numbers.h (SCM_SLOPPY_FRACTIONP): Removed. It was not used
throughout guile, has not been part of an official release yet,
and the concept of sloppy predicates has never been a good idea.
(SCM_FRACTION_NUMERATOR, SCM_FRACTION_DENOMINATOR,
SCM_FRACTION_SET_NUMERATOR, SCM_FRACTION_SET_DENOMINATOR):
Simplified.
2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
* throw.c (SETJBJMPBUF, SCM_SETJBDFRAME): Add cast to scm_t_bits
to make explicit what happens.
2004-05-15 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
* dynl.c (SET_DYNL_HANDLE): Add cast to scm_t_bits to make
explicit what happens.
* guardians.c (TCONC_IN): Use SCM_SET_CELL_OBJECT_x rather than
SCM_SET_CELL_WORD_x when writing scheme objets to cell elements.
2004-05-11 Marius Vollmer <mvo@zagadka.de>
* scmsigs.c (scm_sigaction_for_thread): Validate that the handler
is indeed a procedure when it isn't a number.
2004-05-10 Marius Vollmer <mvo@zagadka.de>
Convert floating point numbers into strings with an arbitrary
radix. Thanks to Richard Todd!
* numbers.c (FLOBUFLEN): Increase so that radix 2 strings will
fit.
(fx): Removed.
(scm_dblprec, fx_per_radix, init_dblprec, init_fx_radix,
number_chars): New, to support variable radices.
(idbl2str): Use above instead of the old base-10 only tables.
(iflo2str): Pass on new RADIX argument to idbl2str.
(scm_number_to_string): Pass radix to iflo2str.
(scm_print_real, scm_print_complex): Explicitly pass radix 10 to
iflo2str.
(scm_init_numbers): Call init_dblprec and init_fx_radix for all
possible radices.
2004-05-10 Kevin Ryde <user42@zip.com.au>
* numbers.c (scm_logbit_p): Correction to test above the end of an
inum. Reported by Jan Konecny.
2004-05-06 Marius Vollmer <marius.vollmer@uni-dortmund.de>
* gc.h (scm_t_cell): Fields are now of type SCM instead of
scm_t_bits. Updated all users.
(SCM_GC_CARD_SIZE_MASK): Use SCM_GC_SIZEOF_CARD instead of
duplicating the code.
(SCM_CELL_OBJECT_LOC): New.
(SCM_CARLOC, SCM_CDRLOC): Use it instead of SCM_CELL_WORD_LOC.
(SCM_CELL_WORD_LOC): Moved to "deprecated.h".
* smob.h (SCM_SMOB_DATA_2, SCM_SMOB_DATA_3, SCM_SMOB_FLAGS,
SCM_SET_SMOB_DATA_2, SCM_SET_SMOB_DATA_3, SCM_SET_SMOB_FLAGS,
SCM_SMOB_OBJECT, SCM_SMOB_OBJECT_2, SCM_SMOB_OBJECT_3,
SCM_SET_SMOB_OBJECT, SCM_SET_SMOB_OBJECT_2, SCM_SET_SMOB_OBJECT_3,
SCM_SMOB_OBJECT_LOC, SCM_SMOB_OBJECT_2_LOC,
SCM_SMOB_OBJECT_3_LOC): New.
* smob.c (scm_i_set_smob_flags): New function.
* dynl.c, dynwind.c, eval.h, fluids.h, futures.h, hashtab.h,
hooks.h, keywords.h, macros.h, macros.c, mallocs.c, mallocs.h,
random.h, regex-posix.h, root.h, srcprop.h, srcprop.c, threads.h:
Use SCM_SMOB_* instead of SCM_CELL_* as appropriate. Use
SCM_SMOB_FLAGS and SCM_SET_SMOB_FLAGS instead of accessing the
zeroth word directly. Use SCM_SMOB_PREDICATE as appropriate.
* numbers.h (SCM_I_BIG_MPZ): Use SCM_CELL_OBJECT_LOC instead of
taking the address of SCM_CELL_WORD_1, the latter being no longer
an lvalue.
* variable.h (SCM_VARIABLE_LOC): Use SCM_CELL_OBJECT_LOC instead
of casting SCM_CELL_WORD_LOC.
2004-05-02 Kevin Ryde <user42@zip.com.au>
* eval.c (scm_macroexp): Add prototype, since it's not in eval.h under
--disable-deprecated. Reported by Andreas Vögele.
* filesys.c (_POSIX_C_SOURCE): Define to 199506L to get readdir_r (in
particular on HP-UX). Reported by Andreas Vögele.
* list.c (varargs.h): Remove, leave just stdarg.h which is all the
code has support for. Fixes building with AIX cc, which is ansi but
doesn't define __STDC__. Reported by Keith Crane.
(var_start): Remove macro, this variation no longer required.
(scm_list_n): Use va_start directly.
2004-05-01 Kevin Ryde <user42@zip.com.au>
* continuations.c (scm_dynthrow): Use >= instead of SCM_PTR_GE which
is now gone. Reported by Andreas Vögele.
2004-04-28 Kevin Ryde <user42@zip.com.au>
* backtrace.c (display_frame_expr), numbers.c (XDIGIT2UINT,
mem2uinteger, mem2decimal_from_point, mem2ureal): Cast char to int for
ctype.h tests, to avoid warnings from gcc on HP-UX about char as array
subscript. Reported by Andreas Vögele.
Also cast through unsigned char to avoid passing negatives to those
macros if input contains 8-bit values.
* num2integral.i.c (NUM2INTEGRAL): Under non-BIGMPZ_FITSP case,
corrections to range check for signed numbers. Remove
scm_remember_upto_here_1(num) from these checks, since num is used
subsequently anyway.
* num2integral.i.c (NUM2INTEGRAL): Test BIGMPZ_FITSP with "!= 0" to
avoid warning from gcc 3.4. Reported by Hyperdivision.
* numbers.c (scm_bit_extract): Use min instead of MIN.
(MIN): Remove, this conflicts with similar macro defined by limits.h
on HP-UX. Reported by Andreas Vögele.
* stime.c (_POSIX_C_SOURCE): Define to 199506L to get gmtime_r (in
particular on HP-UX). Reported by Andreas Vögele.
* threads.c (scm_threads_mark_stacks): Correction sizet -> size_t.
Reported by Andreas Vögele.
* threads-plugin.h (SCM_MUTEX_MAXSIZE): Increase to 25*sizeof(long),
for the benefit of hpux11 where pthread_mutex_t is 88 bytes. Reported
by Andreas Vögele.
2004-04-22 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
* eval.c (s_macro_keyword): New static identifier.
(scm_m_define): Change order to first create binding and
evaluating the expression afterwards.
(scm_m_set_x): Memoize complete set! expression. Only leave
symbols if no binding exists at memoization time. Throw error if
assigning to a syntactic keyword.
(lazy_memoize_variable): New function.
(CEVAL): When execution set!, perform lazy memoization if
unmemoized symbol is detected.
* modules.c (module_variable): Return variables with unbound
value.
* tags.h: Fix comment.
2004-04-25 Kevin Ryde <user42@zip.com.au>
* chars.c (scm_char_upcase, scm_char_downcase, scm_c_upcase,
scm_c_downcase): Use ctype.h toupper and tolower. This will be useful
in 8-bit locales, and ensures consistency with char-upper-case? and
char-lower-case? which already use ctype.h.
(scm_c_upcase_table, scm_c_downcase_table, scm_lowers, scm_uppers):
Remove.
* chars.c, chars.h, init.c (scm_tables_prehistory): Remove.
* socket.c (VALIDATE_INET6): Correction to bignum_in_ipv6_range_p
call. Reported by Hyperdivision.
* threads.c (scm_yield): Correction, actually call scm_thread_yield.
Reported by Hyperdivision.
* unif.c (s_scm_make_uve): Remove unused local variable. Reported by
Hyperdivision.
2004-04-22 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
Hide the implementation of ilocs and isyms in eval.c.
* deprecated.h (SCM_IFRINC, SCM_ICDR, SCM_IFRAME, SCM_IDIST,
SCM_ICDRP), eval.c (SCM_IFRINC, SCM_ICDR, SCM_IFRAME, SCM_IDIST,
SCM_ICDRP), eval.h (SCM_ICDR, SCM_IFRINC, SCM_IFRAME, SCM_IDIST,
SCM_ICDRP): Deprecated and added to deprecated.h. Moved from
eval.h to eval.c.
* deprecated.c (scm_isymnames), deprecated.h (scm_isymnames,
SCM_ISYMNUM, SCM_ISYMCHARS), eval.c (SCM_ISYMNUM, isymnames,
scm_unmemocopy, CEVAL), print.c (scm_isymnames), tags.h
(SCM_ISYMNUM, scm_isymnames, SCM_ISYMCHARS): Deprecated
scm_isymnames, SCM_ISYMNUM and SCM_ISYMCHARS and added to
deprecated.[hc]. Moved scm_isymnames from print.c to eval.c and
renamed to isymnames. Moved SCM_ISYMNUM from tags.h to eval.c and
renamed to ISYMNUM.
* eval.c (scm_i_print_iloc, scm_i_print_isym), eval.h
(scm_i_print_iloc, scm_i_print_isym), print.c (scm_iprin1):
Extracted printing of ilocs and isyms to guile internal functions
scm_i_print_iloc, scm_i_print_isym of eval.c.
2004-04-22 Kevin Ryde <user42@zip.com.au>
* numbers.c (scm_bit_extract): Use SCM_SRS for signed right shift.
* numbers.c (scm_round): Test for x already an integer, to avoid bad
rounding in x+0.5 when x is a big value already an integer. In
certain hardware rounding cases x+0.5 can give an adjacent integer,
leading to that as the result, when we really just wanted x itself.
2004-04-19 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
* eval.c (scm_unmemocopy): Fixed unmemoization of let*.
(deval_args, CEVAL): Minor improvements: Reduced variable scopes,
added const qualifiers, cast intentionally unused expressions to
void for emphasis, improved comment.
2004-04-18 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
* tags.h (scm_tags, scm_tc8_tags, scm_tc9_flag, scm_tc8_flag,
scm_tc8_isym): Renamed scm_tags to scm_tc8_tags. Renamed
scm_tc9_flag to scm_tc8_flag. Introduced new identifier
scm_tc8_isym. Defined tc8-tags relative to scm_tc3_imm24.
Defined the tc8-tag for flags to be 0x04, which will mean that
SCM_BOOL_F will also have the value 0x04 instead of 0x013c. Due
to the reduced number of bits and the simpler bit pattern for
SCM_BOOL_F, certain machines may be able to use more efficient
processor instructions to deal with SCM_BOOL_F.
(SCM_ITAG9, SCM_MAKE_ITAG9, SCM_ITAG9_DATA): Removed. These have
never been defined in a released version, thus no need to
deprecate them.
(SCM_IFLAGP, SCM_MAKIFLAG, SCM_IFLAGNUM): Flags now use tc8
instead of tc9 tags.
(SCM_ISYMP, SCM_MAKISYM, SCM_ISYMNUM): Isyms now use tc8 instead
of tc9 tags.
(SCM_MAKSPCSYM): Removed. It is almost impossible that user code
could have used this definition.
(SCM_IM_AND, SCM_IM_BEGIN, SCM_IM_CASE, SCM_IM_COND, SCM_IM_DO,
SCM_IM_IF, SCM_IM_LAMBDA, SCM_IM_LET, SCM_IM_LETSTAR,
SCM_IM_LETREC, SCM_IM_OR, SCM_IM_QUOTE, SCM_IM_SET_X): Now encoded
as isyms, as special isyms don't exist any more.
2004-04-18 Kevin Ryde <user42@zip.com.au>
* filesys.c (scm_readdir): Use readdir_r when available, for thread
safety.
* numbers.c (scm_max, scm_min): For big/real, use SCM_SWAP rather than
explicit swapping code.
2004-04-15 Kevin Ryde <user42@zip.com.au>
* cpp_sig_symbols.in: Add SIGSYS.
* list.c (scm_append_x): Use iterative style, to avoid non-tail
recursion.
* numbers.c (scm_max, scm_min): For inum/frac, frac/inum, big/frac,
frac/big and frac/frac, use scm_less_p for exact comparison.
* numbers.c (scm_gcd): For inum/big, use mpz_gcd_ui by sharing code
with big/inum.
* numbers.c (xisinf): Add a comment about solaris 7 lacking isinf.
2004-04-06 Han-Wen Nienhuys <hanwen@xs4all.nl>
* inline.h (scm_cell): use SCM_GC_CELL_WORD for checking tag.
* chars.h (scm_init_chars): change scm_{upcase,downcase} to
scm_c_{up,down}case.
(SCM_MAKE_CHAR): add (unsigned char) cast. This prevents havoc
when hi-bit ASCII is subjected to SCM_MAKE_CHAR().
2004-04-06 Kevin Ryde <user42@zip.com.au>
* numbers.c (scm_ash): Remove stray "}" in docstring.
* numbers.c (scm_make_ratio): For inum/bignum integer detection, use
x==SCM_MOST_NEGATIVE_FIXNUM explicitly, for clarity and to avoid
calling mpz_cmp_ui in most cases.
* numbers.c (scm_quotient, scm_remainder): In inum/big, use mpz_cmp_ui
for big == abs(most-negative-fixnum) special case.
(abs_most_negative_fixnum): Remove, no longer used.
* scmsigs.c (scm_sigaction_for_thread): Correction to signum range
test, avoids SCM_VECTOR_REF outside bounds of signal_handlers on
calling (sigaction NSIG).
* simpos.c (scm_system_star): Fix execargv memory leak, merge parent
and fork error cases to do this.
2004-04-03 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
* eval.c (CEVAL): Don't distinguish between short and long
instructions when dispatching - just always dispatch on the
instruction code, which is common for short and long instructions.
Further, removed unnecessary goto statements and added comment.
2004-04-03 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
* eval.c (scm_unmemocopy): Don't distinguish between short and
long instructions when dispatching - just always dispatch on the
instruction code, which is common for short and long instructions.
Further, removed unnecessary goto statements, fixed indentation
and replaced SCM_IMP predicates by SCM_NULLP.
2004-04-03 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
* eval.c (scm_lookupcar1, CEVAL): Use SCM_ILOCP instead of
comparison with SCM_ILOC00. In CEVAL, eliminate goto-label
'checkmacro'.
2004-03-31 Kevin Ryde <user42@zip.com.au>
* simpos.c: Include <signal.h> for SIG_IGN and friends.
2004-03-29 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
Introduce scm_debug_mode_p as a replacement for scm_debug_mode and
SCM_DEBUGGINGP:
* debug.h (scm_debug_mode_p, scm_debug_mode, SCM_DEBUGGINGP),
eval.c (scm_debug_mode_p): Deprecated scm_debug_mode and
SCM_DEBUGGINGP. Provided scm_debug_mode_p instead, to have one
single interface that also matches the naming conventions.
Probably scm_debug_mode_p should be part of the private interface
anyway.
* debug.h (scm_debug_mode_p), backtrace.c (display_error_body),
eval.c (SCM_APPLY, scm_trampoline_0, scm_trampoline_1,
scm_trampoline_2): Change uses of scm_debug_mode or SCM_DEBUGGINGP
to scm_debug_mode_p.
Deprecate direct access to scm_ceval, scm_deval and scm_ceval_ptr:
* eval.h (scm_ceval, scm_deval, scm_ceval_ptr), debug.h
(scm_ceval_ptr): Deprecated. Moved declaration of scm_ceval_ptr
from debug.h to eval.h.
* debug.h (SCM_RESET_DEBUG_MODE): Don't access scm_ceval_ptr any
more, just leave it with setting scm_debug_mode_p, which is
equivalent for practical purposes.
* deprecated.h (SCM_XEVAL, SCM_XEVALCAR): Call scm_i_eval_x
instead of *scm_ceval_ptr. Leave all evaluating to scm_i_eval_x.
* gdbint.c (gdb_eval): Call scm_i_eval_x instead of scm_ceval.
* eval.c (ceval, deval, scm_ceval, scm_deval): Made scm_ceval
static and renamed it to ceval throughout. Provide a new exported
but deprecated function scm_ceval as a wrapper for backwards
compatibility. The same is done for the deval/scm_deval pair of
functions.
* eval.c (CEVAL, SCM_CEVAL): Renamed SCM_CEVAL to CEVAL
throughout. Defined CEVAL to ceval or deval, based on compilation
phase.
* eval.c (SCM_XEVAL, SCM_XEVALCAR): Dispatch on scm_debug_mode_p
to ceval and deval instead of calling *scm_ceval_ptr.
* eval.c (dispatching_eval): New deprecated static function.
* eval.c (scm_ceval_ptr): Initialized to dispatching_eval in order
to emulate its old behaviour as closely as possible.
Change the evaluator such that only expressions for which pair? is
true are passed to CEVAL, and such that all other expressions are
evaluated outside of CEVAL:
* eval.c (EVAL): New, provided in analogy to EVALCAR. Evaluate an
expression that is assumed to be memoized already. All but
expressions of the form '(<form> <form> ...)' are evaluated inline
without calling an evaluator.
* eval.c (SCM_XEVAL, SCM_XEVALCAR, EVALCAR): Evaluate all but
expressions of the form '(<form> <form> ...)' inline without
calling an evaluator.
* eval.c (scm_i_eval_x, scm_i_eval, scm_ceval, scm_deval): Handle
the special case of unmemoized symbols passed on the top level.
* eval.c (CEVAL): Change calls to CEVAL to EVAL, except where it
is known that the expression passed to CEVAL is of the form
'(<form> <form> ...)'. Remove handling of the tc7-objects, since
now it is known that the input expression of CEVAL is a pair.
2004-03-29 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
* eval.c (is_self_quoting_p): New static function.
(scm_m_quote): Use is_self_quoting_p.
(copy_tree): Corrected typo in comment.
2004-03-28 Han-Wen Nienhuys <hanwen@xs4all.nl>
* eval.c (s_scm_copy_tree): idem.
* list.c (s_scm_filter): remove "pointer" from doc string.
* gc.h (SCM_GC_CELL_TYPE): SCM_GC_CELL_TYPE uses SCM_GC_CELL_OBJECT.
* goops.h (SCM_NUMBER_OF_SLOTS): don't SCM_UNPACK the result.
* backtrace.c ("display_backtrace_body"): SCM_PACK before SCM_EQ_P
(display_frame): idem.
(display_backtrace_file_and_line): idem.
* tags.h (SCM_UNPACK): stricter typechecking on SCM_UNPACK
arguments.
2004-03-26 Kevin Ryde <user42@zip.com.au>
* filesys.c (scm_getcwd, scm_readlink): Avoid memory leak on errors.
* numbers.c (scm_modulo): For inum/big and big/big, remove test of
big==0 since that never occurs.
* numbers.c, numbers.h (scm_modulo_expt): Renamed from
scm_modular_expt, matching scheme level name `modulo-expt'.
* numbers.c (scm_modular_expt): Return a negative remainder for a
negative divisor, the same as `modulo' does.
2004-03-26 Eric Hanchrow <offby1@blarg.net>
* numbers.c, numbers.h (scm_modular_expt): New function.
2004-03-25 Kevin Ryde <user42@zip.com.au>

return inexact as required by r5rs.
2004-03-24 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
* eval.c: Separated some definitions relevant for execution from
the memoization part of the file.
(copy_tree): New static function
(scm_copy_tree): Rewritten to fix two kinds or bugs: First, cyclic
structures are detected now and will lead to an exception instead
of forcing guile to run in an endless loop, using up all the
system's memory. Second, arrays in the cdr of an improper list
are now copied. See the new test cases in eval.test.
2004-03-24 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
* posix.c (scm_gethostname): Make sure len is initialised before
it is used. Restructured to (hopefully) represent possible
configurations more clearly in the code. Added unwind handler.
2004-03-23 Kevin Ryde <user42@zip.com.au>
* posix.c (scm_gethostname): Use sysconf(_SC_HOST_NAME_MAX) and/or
MAXHOSTNAMELEN when available.
2004-03-21 Marius Vollmer <mvo@zagadka.de>
* read.c (skip_scsh_block_comment): Also recognize '\r' as a line
terminator. Rewritten the logic as a state machine, I must have
been doing too much VHDL lately...
* eval.c (scm_ceval, scm_deval): Explicitely evaluate ports to
themselves. Thanks to Han-Wen Nienhuys!
* list.c: Changed docstrings so that they no longer talk about
returning 'pointers' to something.
2004-03-20 Han-Wen Nienhuys <hanwen@xs4all.nl>
* gc.c: remove set_debug_cell_accesses! when
SCM_DEBUG_CELL_ACCESSES is not defined. Scheme source code should
use (if (defined? 'set-debug-cell-accesses!) .. ) to switch on
debugging conditionally.
2004-03-21 Kevin Ryde <user42@zip.com.au>
* stime.c (scm_gmtime): Use gmtime_r when available, for thread safety.
2004-03-20 Kevin Ryde <user42@zip.com.au>

free cells.
2004-03-14 Kevin Ryde <user42@zip.com.au>
* stime.c: Define _GNU_SOURCE for strptime prototype from glibc.
(strptime): Use HAVE_DECL_STRPTIME for when to give own prototype.
2004-03-07 Kevin Ryde <user42@zip.com.au>
* stime.c (scm_gmtime): Return bd_time->tm_zone when available, rather
than "GMT" always.
(filltime): Make zname parameter "const".
2004-03-03 Mikael Djurfeldt <mdj@chunk.mit.edu>
* threads.c, threads.h (scm_c_scm2thread): New function.
2004-02-29 Kevin Ryde <user42@zip.com.au>
* numbers.c (guile_ieee_init): Use C99 INFINITY and NAN when
available. Test HAVE_DINFINITY and HAVE_DQNAN for those globals, in
particular don't assume "defined (__alpha__) && ! defined (linux)"
means OSF. Remove "SCO" code, which was not really SCO specific and
which John W. Eaton advises should be long past being needed.
* posix.c (scm_execl, scm_execlp, scm_execle): Avoid memory leak under
error throw.
2004-02-24 Kevin Ryde <user42@zip.com.au>
* posix.c (scm_cuserid): Use a private result buffer, for thread safe.
2004-02-22 Kevin Ryde <user42@zip.com.au>
* numbers.c (scm_max, scm_min): For one arg, dispatch to generic for
complex, same as for two args. (Handle only inum, big, real, frac).
2004-02-21 Kevin Ryde <user42@zip.com.au>
* posix.c (scm_crypt): Use new HAVE_CRYPT.
(<crypt.h>): Remove HAVE_LIBCRYPT condition.
Reported by Andreas Voegele.
2004-02-20 Neil Jerram <neil@ossau.uklinux.net>
* list.c (scm_list_n): Add #if SCM_DEBUG_CELL_ACCESSES_P around
validation.
* read.c (scm_lreadparen): Removed.
(scm_lreadparen1): Renamed scm_i_lreadparen.
2004-02-20 Han-Wen Nienhuys <hanwen@xs4all.nl>
* list.c (scm_list_n): validate non-immediate arguments;
this will catch forgotten a SCM_UNDEFINED.
2004-02-18 Marius Vollmer <mvo@zagadka.de>
* gc.h (scm_gc_cells_collected): Removed duplicated declaration.
Thanks to Bill Schottstaedt!
* socket.h (scm_gethost): Removed prototype it is already in
"net_db.h". Thanks to Bill Schottstaedt!
2004-02-18 Kevin Ryde <user42@zip.com.au>
* num2integral.i.c (INTEGRAL2BIG): WORDS_BIGENDIAN not right for word
order parameter to mpz_import, in fact with just one word there's no
order to worry about at all.
* numbers.c (scm_num_eq_p): For real==frac, complex==frac, frac==real
and frac==complex, make an exact comparison rather than converting
with fraction2double.
* posix.c, putenv.c, stime.c (environ): Use _NSGetEnviron in Darwin
shared library, since environ is not directly available there.
* script.c (scm_shell_usage): Print to stdout for --help, per GNU
standard.
* stime.c (scm_localtime, scm_gmtime, scm_mktime): Provide a default
errno EINVAL in case localtime and gmtime don't set it.
(scm_mktime, scm_strptime): Forcibly use errno EINVAL for our
SCM_SYSERROR, since mktime and strptime generally don't set errno.
2004-02-16 Kevin Ryde <kevin@swox.se>
* gc-malloc.c (scm_done_malloc, scm_done_free): Allow negative sizes,
which were permitted in the past for these.
* num2float.i.c (NUM2FLOAT): Expand isfinite to !xisinf, as per
previous change to numbers.c.
* script.c (scm_shell_usage): Print bug-guile email address, as per
GNU standard. Reported by Han-Wen Nienhuys.
2004-02-13 Mikael Djurfeldt <djurfeldt@nada.kth.se>
* unif.c (scm_make_uve): Removed local variable and simplified
code in order to avoid compiler used uninitialized warnings.
* hashtab.c, hashtab.h (scm_hash_map_to_list): Renamed from
scm_hash_map.
(scm_hash_fold): Use scm_call_3 directly in the call to
scm_internal_hash_fold instead of going via fold_proc (which is
now removed).
(scm_hash_for_each): Use a trampoline +
scm_internal_hash_for_each_handle.
(scm_internal_hash_for_each_handle, scm_hash_for_each_handle): New
functions.
2004-02-12 Kevin Ryde <user42@zip.com.au>
* ports.c (scm_port_line): In docstring, note first line is 0.
(scm_set_port_line_x): In docstring, note first line is 0.
(scm_port_column): In docstring, there's no default to current input
port, and remove shared port-line @defun.
(scm_set_port_column_x): In docstring, there's no default to current
input port, note first column is 0, remove shared set-port-line!
@defun.
* ramap.c (scm_array_fill_x): For fvect and dvect, use scm_num2dbl to
convert args the same way that array-set! does.
* unif.c (scm_make_uve, scm_array_p): Allow fraction 1/3 as prototype
for dvect.
(scm_array_p): Add missing "break"s in switch, fix llvect test look
for "l" not "s", fix dvect to be false for singp(prot) since such a
value is for fvect.
(scm_array_prototype): Return 1/3 for dvect, rather than 0.33..33.
(exactly_one_third): New variable.
(scm_init_unif): Initialize it.
2004-02-10 Neil Jerram <neil@ossau.uklinux.net>
* read.c (scm_read_opts): Change `escaped-parens' to
`elisp-strings'.
2004-02-08 Neil Jerram <neil@ossau.uklinux.net>
* read.c (scm_read_opts): New opts `elisp-vectors' and
`escaped-parens'.
(s_vector): New.
(scm_lreadr): Use scm_lreadparen1 instead of scm_lreadparen. Make
handling of elisp vector syntax dependent on SCM_ENABLE_ELISP and
`elisp-vectors' option instead of SCM_ELISP_READ_EXTENSIONS.
Allow "\(" and "\)" in strings when SCM_ENABLE_ELISP defined and
`escaped-parens' option set.
(scm_read_token): If elisp vector syntax active, disallow [ and ]
in tokens.
(scm_lreadparen): Rewrite as interface to scm_lreadparen1.
(scm_lreadparen1): New.
* read.h: Remove conditionally compiled last arg to
scm_lreadparen.
(SCM_ELISP_VECTORS_P, SCM_ESCAPED_PARENS_P): New.
2004-01-23 Han-Wen Nienhuys <hanwen@xs4all.nl>
* eval.c (m_expand_body): remove stray variable new_body.
2004-01-22 Marius Vollmer <mvo@zagadka.de>
* eval.c (m_expand_body): Rewrite the expression in place (by
overwriting FORMS) also when a letrec is constructed, not only
when no definitions are found. Do not return rewritten expression
to emphasize the in-place rewriting. Changed all users.
2004-01-19 Han-Wen Nienhuys <hanwen@xs4all.nl>
* gc.c: add protected_object_count, a number that is dumped from
gc_stats()
2004-01-11 Marius Vollmer <mvo@zagadka.de>
* dynwind.h, dynwind.c (scm_frame_unwind,
scm_frame_unwind_handler): Renamed and changed all uses.
(scm_frame_rewind, scm_frame_rewind_handler): Likewise.
2004-01-11 Kevin Ryde <user42@zip.com.au>
* unif.c (scm_bit_count, scm_bit_position, s_scm_bit_set_star_x,
s_scm_bit_count_star, s_scm_bit_invert_x): Clarify docstrings, as per
changes made to scheme-compound.texi.
2004-01-10 Marius Vollmer <mvo@zagadka.de>
* print.c (scm_print_symbol_name): Handle #{`foo}#, #{,foo}#,
#{.}#, and all numeric strings specially. Thanks to Paul Jarc!
* guile-snarf.in: Use mkdir to create a unique temporary directory
that we can safely use. Thanks to Stefan Nordhausen!
2004-01-07 Marius Vollmer <marius.vollmer@uni-dortmund.de>
* dynwind.h, dynwind.c (scm_i_dowinds): Removed 'explicit'
argument since it is always zero now. Changed all callers.
Removed code for handling fluids.
* fluids.c (scm_c_with_fluids): Use frames instead of adding to
the wind chain explicitely. Use scm_c_with_fluid for the common
case of only one fluid.
(scm_with_fluid): New.
(scm_c_with_fluid): Use frames instead of scm_c_with_fluids.
* fluids.h, fluids.c (scm_frame_fluid): New.
(scm_with_fluid): New.
(scm_i_swap_fluids, scm_i_swap_fluids_reverse): Removed.
* dynwind.c (scm_frame_end): Do not use scm_i_dowinds. Instead,
do the unwinding directly. It is simple enough.
* dynwind.h, dynwind.c: Did the following renamings:
scm_begin_frame -> scm_frame_begin,
scm_end_frame -> scm_frame_end,
scm_on_unwind -> scm_frame_unwind,
scm_on_rewind -> scm_frame_rewind,
scm_on_unwind_with_scm -> scm_frame_unwind_with_scm,
scm_on_rewind_with_scm -> scm_frame_rewind_with_scm.
Changed all uses.
* aync.h, async.c: Did the follwing renamings:
scm_with_blocked_asyncs -> scm_frame_block_asyncs,
scm_with_unblocked_asyncs -> scm_frame_unblock_asyncs.
Changed all uses.
* ports.h, ports.c: Did the follwing renamings:
scm_with_current_input_port -> scm_frame_current_input_port,
scm_with_current_output_port -> scm_frame_current_output_port,
scm_with_current_error_port -> scm_frame_current_error_port.
Changed all uses.
2004-01-07 Kevin Ryde <user42@zip.com.au>
* numbers.c (s_bignum): Remove, not used since gmp bignums.
Reported by Richard Todd.
* threads-plugin.h (SCM_MUTEX_MAXSIZE): Increase to 12*sizeof(long),
for the benefit of powerpc-apple-darwin5.5. Reported by Richard Todd.
* unif.c (scm_aind): Test SCM_CONSP rather than !SCM_NULLP while
traversing the args list, fixes segv if an improper list is given.
Reported by Rouben Rostamian.
2004-01-06 Marius Vollmer <marius.vollmer@uni-dortmund.de>
* ports.c (swap_ports, scm_with_current_foo_port): Do not allocate
swap_data on stack, use a 'malloc obj'.
* fluids.h, fluids.c (scm_make_initial_fluids, scm_copy_fluids,
scm_swap_fluids, scm_swap_fluids_reverse): Renamed to
scm_i_... since they are internal. Changed all uses.
* dynwind.c (frame_print): Removed, use the default printer.
(WINDER_F_MARK, WINDER_MARK_P, winder_mark): New.
(scm_on_unwind_with_scm, scm_on_rewind_with_scm): New. Use above
to protect SCM values.
* dynwind.h (SCM_F_WIND_EXPLICITELY,
SCM_F_WIND_EXPLICITLY): It's "explicitly" not "explicitely", damn.
Changed all uses.
(scm_on_unwind_with_scm, scm_on_rewind_with_scm): New.
2004-01-05 Marius Vollmer <mvo@zagadka.de>
* ports.h, ports.c (scm_with_current_input_port,
scm_with_current_output_port, scm_with_current_error_port): New.
* async.h, async.c (scm_with_blocked_asyncs,
scm_with_unblocked_asyncs): New.
2004-01-03 Marius Vollmer <mvo@zagadka.de>
* dynwind.h, scm_dynwind.c (scm_t_frame_flags, scm_t_wind_flags,
scm_begin_frame, scm_end_frame, scm_on_unwind, scm_on_rewind):
New.
(scm_dowinds, scm_i_dowinds): scm_dowinds has been renamed to
scm_i_dowinds and extended to handle frames and to invoke a 'turn'
function when the outermost wind point has been reached. The
latter is used to copy a continuation stack at the right time.
scm_dowinds remains available.
(SCM_GUARDSP, SCM_BEFORE_GUARD, SCM_AFTER_GUARD, SCM_GUARD_DATA,
tc16_guard, guards_print): Removed.
(scm_internal_dynamic_wind): Reimplemented using frames.
* continuations.c (copy_stack): New, do only the stack copying
part of copy_stack_and_call.
(copy_stack_and_call): Copy the stack after unwinding and before
rewinding.
(scm_dynthrow): Do not call scm_dowinds, this is now done by
copy_stack_and_call.
2004-01-04 Kevin Ryde <user42@zip.com.au>
* numbers.c (scm_less_p): Don't convert frac to float for compares,
can give bad results due to rounding.
* stime.c (scm_current_time, scm_gettimeofday): Add a comment about
setzone/restorezone protection for DOS.
2003-12-26 Marius Vollmer <mvo@zagadka.de>
* gen-scmconfig.h.in, gen-scmconfig.c: Arrange for scm_t_intmax
and scm_t_uintmax to be defined in scmconfig.h
2003-12-03 Kevin Ryde <user42@zip.com.au>
* numbers.c (scm_less_p): Remove spurious xisnan from frac+big case.
* numbers.c (scm_make_ratio): Check for numerator equal to
SCM_MOST_NEGATIVE_FIXNUM and bignum denominator the negative of that,
giving integer -1.
* numbers.c (scm_real_part): Return fraction unchanged rather than
converting to flonum.
2003-11-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
* modules.c (module_variable): Fixed (and thus simplified) the
definition of SCM_BOUND_THING_P to reflect the fact that since
after the 1.4 series of guile, obarrays only hold variable
objects.
2003-11-30 Marius Vollmer <mvo@zagadka.de>
* numbers.c (scm_logand): It's "#b...", not "#\b...".
From Paul Jarc:
* read.c (scm_lreadr): Signal an error for invalid escape
sequences in strings. Code cleanups too.
* print.c (scm_iprin1): use \xNN hexadecimal sequences when
writing control characters in strings.
2003-11-21 Marius Vollmer <mvo@zagadka.de>
* ports.c (scm_drain_input): Bug fix: only access the port after
checking that it indeed is one.
2003-11-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
* eval.c (s_bad_define): New static identifier.
(m_body): Fixed comment.
(scm_m_define): Don't generate memoized code for definitions that
are not on the top level. As a consequence, no memoized code at
all is generated for definitions any more: Top level definitions
are executed immediately during memoization and internal
definitions are handled separately in m_expand_body.
(scm_unmemocopy, unmemocopy): Removed code for unmemoizing
definitions. Consequently, there is no unmemoizing code any more
that might modify the environment. Thus, the old scm_unmemocopy
is removed and the old unmemocopy is renamed to scm_unmemocopy.
(SCM_CEVAL): The SCM_IM_DEFINE keyword can no longer occur in
memoized code. Call EVALCAR for continuations. Prefer !SCM_NULLP
over SCM_NIMP in places, where the argument is known to be part of
a proper list.
2003-11-21 Kevin Ryde <user42@zip.com.au>
* numbers.c (scm_abs): Allocate a new real only for negatives, as done
for bignums.
* numbers.c (scm_bit_extract): Use mpz functions, rearrange inum case
to share some shifting.
* numbers.c (scm_integer_expt): Don't mpz_init after scm_i_clonebig or
scm_i_mkbig, since they do so already. Don't mpz_clear a bignum SCM,
since gc does this.
2003-11-19 Marius Vollmer <mvo@zagadka.de>
* numbers.c (scm_make_ratio): Rewritten to have a simpler
structure. Previously, not all cases with a negative denominator
were covered.
* numbers.c (mem2decimal_from_point): use scm_divide instead of
scm_divide2real when forming the fractional part. This allows
"#e1.2" to yield 6/5.
* numbers.c (scm_i_fraction_equalp): Do not treat the return value
of scm_equal_p as a C boolean, use SCM_FALSEP. Previously, all
fractions were equal to each other regardless of value. Ooops.
* numbers.c (scm_rationalize): Return an inexact result when given
inexact arguments.
* numbers.c (scm_exact_p, scm_inexact_p): Throw error for
non-numbers.
2003-11-18 Marius Vollmer <marius.vollmer@uni-dortmund.de>

New exact functions that replace the inexact 'dsubr'
implementations.
(scm_numerator, scm_denominator): New.
* numbers.h (SCM_NUMP): Recognize fractions.
(SCM_FRACTIONP, SCM_SLOPPY_FRACTIONP, SCM_FRACTION_NUMERATOR,
SCM_FRACTION_DENOMINATOR, SCM_FRACTION_SET_NUMERATOR,
SCM_FRACTION_SET_DENOMINATOR, SCM_FRACTION_REDUCED_BIT,
SCM_FRACTION_REDUCED_SET, SCM_FRACTION_REDUCED_CLEAR,
SCM_FRACTION_REDUCED): New.
(scm_floor, scm_ceiling, scm_truncate_number, scm_round_number):
New prototypes.
(scm_make_ratio, scm_rationalize, scm_numerator, scm_denominator,
scm_rational_p): New prototypes.
(scm_i_dbl2num, scm_i_fraction2double, scm_i_fraction_equalp,
scm_i_print_fraction): New prototypes.
* goops.c (create_standard_classes): Create "<fraction>" class.
* gc-mark.c (scm_gc_mark_dependencies): Handle fractions.
* gc-card.c (scm_i_sweep_card): Include scm_tc16_fraction as a
case in the switch, but do nothing for now.
* eval.c (SCM_CEVAL, SCM_APPLY, call_dsubr_1): Convert fractions
to doubles when calling 'dsubr' functions.
* eq.c (scm_eqv_p, scm_equal_p): Handle fractions.
2003-11-18 Rob Browning <rlb@defaultvalue.org>
* gen-scmconfig.c (main): remove public definition of
SCM_SIZEOF___INT64 and SCM_SIZEOF_UNSIGNED___INT64 and add
direct typedef of long_long and ulong_long inside deprecated block
when appropriate.
* deprecated.h: move long_long and ulong_long definitions to
gen-scmconfig.c so that we don't need to add SCM_SIZEOF___INT64
and SCM_SIZEOF_UNSIGNED___INT64 to the public namespace.
2003-11-17 Marius Vollmer <mvo@zagadka.de>
* hash.c (scm_string_hash): New hashing algorithm that takes the
complete string into account.
* eval.c (scm_m_generalized_set_x): Macroexpand the target when it
is a list. This allows (@ ...) to work with set!.
(scm_m_generalized_set_x): Use ASSERT_SYNTAX_2 instead of
SCM_ASSYNT.
* script.c (scm_compile_shell_switches): Use scm_c_read_string for
the "-e" option instead of scm_str2symbol. This allows things

numbers. Bignums, reals and complex numbers are turned from smobs
into subtypes of scm_tc7_number.
* tags.h (scm_tc7_number): New.

(scm_hasher), numbers.c, numbers.h (SCM_NUMP), objects.c
(scm_class_of), print.c (scm_iprin1), smob.c
(scm_smob_prehistory): Don't handle bignums, reals and complex
numbers as subtypes of scm_tc7_smob any more.

2003-09-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
This set of patches eliminates the dependency between the
implementation of evaluator specific memoization codes and special
constants like #f, '() etc. ('flags'), which are not evaluator
specific. The goal is to remove definitions of evaluator
memoization codes completely from the public interface. This will
make it possible to experiment more freely with optimizations of
guile's internal representation of memoized code.
* objects.c (scm_class_of): Eliminate dependency on SCM_ISYMNUM.
* print.c (iflagnames): New array, holding the printed names of
guile's special constants ('flags').
(scm_isymnames): Now holds only the printed names of the
memoization codes.
(scm_iprin1): Separate the handling of memoization codes and
guile's special constants.
* tags.h (scm_tc9_flag, SCM_ITAG9, SCM_MAKE_ITAG9, SCM_ITAG9_DATA,
SCM_IFLAGNUM): new
(scm_tc8_char, scm_tc8_iloc, SCM_BOOL_F, SCM_BOOL_T,
SCM_UNDEFINED, SCM_EOF_VAL, SCM_EOL, SCM_UNSPECIFIED, SCM_UNBOUND,
SCM_ELISP_NIL, SCM_IM_DISPATCH, SCM_IM_SLOT_REF,
SCM_IM_SLOT_SET_X, SCM_IM_DELAY, SCM_IM_FUTURE,
SCM_IM_CALL_WITH_VALUES, SCM_IM_NIL_COND, SCM_IM_BIND): Changed
values.
(SCM_IFLAGP): SCM_IFLAGP now only tests for flags.
(SCM_IFLAGP, SCM_MAKIFLAG, SCM_IFLAGNUM): Generalized to use the
tc9 macros and scm_tc9_flag.
2003-09-15 Marius Vollmer <mvo@zagadka.de>
* posix.c (scm_setgroups): Check that the gid list is not too
long. Thanks to Paul Jarc!
2003-09-14 Dirk Herrmann <D.Herrmann@tu-bs.de>
* tags.h: Reduced the number of short instructions from 14 to 13.
The typecode of the former 14th short instruction is now used to
represent long instructions. Changed some comments to reflect
this fact.
(SCM_MAKISYM): ISYMs get a new tc7 code, namely the one that was
previously used by SCM_IM_DEFINE.
(SCM_IM_DEFINE): Turned into a long instruction.
* eval.c (unmemocopy, SCM_CEVAL): Treat SCM_IM_DEFINE as a long
instruction.
* eval.c (SCM_CEVAL): Since characters and iflags have now a tc7
code that is separate from all instructions, one level of dispatch
for long instructions can be eliminated.
* print.c (scm_isymnames): Removed some commented code.
2003-09-12 Marius Vollmer <mvo@zagadka.de>
* __scm.h (SCM_FENCE): Use __memory_barrier with the Intel
compiler on IA64.
* hashtab.h (scm_tc16_hashtable): Added "extern" declaration.
* modules.c (scm_module_reverse_lookup): Check that the obarray
really is a hashtable and do nothing if not.
* inline.h: Use "extern inline" only with GCC. Use "static
inline" else.
2003-09-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
* numbers.h (SCM_INEXACTP, SCM_REALP, SCM_COMPLEXP): Removed uses
of SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP.
* numbers.h, deprecated.h (SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP,
SCM_SLOPPY_COMPLEXP): Deprecated and moved from numbers.h to
deprecated.h.
2003-09-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
* eq.c (scm_eqv_p, scm_equal_p): Removed uses of
SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP.
* eq.c (scm_eqv_p, scm_equal_p): Reordered comparisons from
0.0==some_expression to some_expression==0.0. The latter is
better readable. The former is preferred by some people, since it
leads to a compiler error when confusing == with =. However, when
using gcc, a warning will be issued if in an if-statement an
assigment appears. Since many Guile developers are using gcc,
such errors will not remain unnoticed anyway. We can therefore
focus on better readability.
2003-09-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
* tags.h: Added description of Guile's type system. Removed some
old and misleading comments.
2003-09-04 Dirk Herrmann <D.Herrmann@tu-bs.de>

respective SLOPPY macro.
2003-09-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
* eq.c (scm_equal_p): Use SCM_TYP7 to check if an object is of
type string, not SCM_TYP7S.
2003-09-03 Kevin Ryde <user42@zip.com.au>
* numbers.c (scm_lognot): Correction to docstring, ones-complement not
2s-complement.
* stime.c (scm_strptime): Add comment about glibc strptime %s and
current timezone requiring SCM_DEFER_INTS.
2003-08-30 Neil Jerram <neil@ossau.uklinux.net>
* script.c (scm_compile_shell_switches): Make -s switch optional
if file to be loaded does not begin with a `-'. (Thanks to Aaron
VanDevender for the patch!)
2003-08-30 Kevin Ryde <user42@zip.com.au>
* numbers.c (scm_lognot): Rewrite using ~ and mpz_com, for directness
and to have non-integer types rejected as per other logical funcs.
2003-08-28 Kevin Ryde <user42@zip.com.au>

2003-08-23 Kevin Ryde <user42@zip.com.au>

thread safe, and could take a long time too.
2003-08-22 Kevin Ryde <user42@zip.com.au>
* numbers.c (scm_difference): Correction to bignum - negative inum.
2003-08-14 Kevin Ryde <user42@zip.com.au>

[__GNUC__]: Use volatile asm macros rather than a function call.
* gc.c (scm_remember_upto_here_1, scm_remember_upto_here_2): Undefine
macros while defining functions.
* simpos.c (getenv): Use <stdlib.h> for prototype.
(scm_system): In docstring, refer to status:exit-val rather than
"functions above".
2003-08-09 Kevin Ryde <user42@zip.com.au>
* srcprop.c (scm_source_properties): Return plist from hash if it's a
list set by source-properties! rather than an SRCPROPS object,
2003-07-29 Kevin Ryde <user42@zip.com.au>
* properties.c (scm_primitive_property_ref): In docstring, note
parameters to not-found-proc, use hyphens rather than underscores for
that parameter name.
(scm_primitive_property_set_x): In docstring, VAL is the value
parameter not CODE.
2003-07-27 Marius Vollmer <mvo@zagadka.de>

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

* numbers.c (scm_odd_p, scm_even_p): Bugfix: Treat result of
scm_inf_p test as Scheme values.

* list.c (scm_list_n): Ditto.
* gc-malloc.c (scm_gc_realloc): Define "ptr" at start of function.
2003-07-08 Matthias Koeppe <mkoeppe@merkur.math.uni-magdeburg.de>
* tags.h (scm_t_bits, scm_t_signed_bits, etc): Avoid solaris empty
defines of INTPTR_MAX and UINTPTR_MAX, combine conditionals for
scm_t_bits and scm_t_signed_bits to avoid any chance of one and not
the other using intptr_t.
2003-07-08 Kevin Ryde <user42@zip.com.au>
* numbers.c (scm_make_polar): Use sincos, when available.
(scm_magnitude): Use hypot.
* ports.c (scm_char_ready_p, scm_peek_char): In docstrings, don't use
@footnote since it doesn't go through to guile-procedures.txt.
* threads.c (scm_call_with_new_thread): In docstring, use "( )"
outside @var to quieten makeinfo, and use @code.
2003-07-06 Han-Wen Nienhuys <hanwen@cs.uu.nl>
* gc-malloc.c (decrease_mtrigger): new function
(increase_mtrigger): new function, separate debug registering and
mtrigger administration.
(scm_gc_realloc): bugfix: do mtrigger administration before the
actual realloc, for the realloc might invalidate a GC-d segment of
memory. Thanks to Sam Hocevar for pointing this out.
(scm_gc_realloc): use scm_malloc_reregister instead of
unregistering and registering in sequence.
2003-07-03 Han-Wen Nienhuys <hanwen@cs.uu.nl>

real part of the API.
* posix.c (s_scm_putenv): Added some code to make a
(putenv "FOO="), i.e. setting an empty string, work also on
Win32 systems. Thanks to Kevin Ryde for the proposal.
2003-06-12 Kevin Ryde <user42@zip.com.au>
* posix.c (scm_putenv): Free temporary ptr in mingw unset. Add
freebsd to comment about need to use unsetenv.
2003-06-02 Marius Vollmer <mvo@zagadka.de>

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

and friends required by scm_t_bits setups.
2003-06-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
* tags.h (scm_tc2_int): Added.
* tags.h (scm_tc3_int_1, scm_tc3_int_2): Expressed in terms of
scm_tc2_int.
* tags.h (scm_tcs_cons_imcar, scm_tcs_cons_nimcar, scm_tcs_struct,
scm_tcs_closures): Hard coded values replaced by symbolic ones.
2003-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
* eval.c: Partially undid my patch from 2003-05-31. This patch
caused the segfault referenced in the previous changelog entry.
2003-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
* tags.h: Fixed comment about the immediate type code layout.
* eval.c: Fixed handling of non-special instructions. Without
this patch, guile will segfault on (#\0) and similar instructions.
2003-06-05 Kevin Ryde <user42@zip.com.au>
* numbers.c (scm_max, scm_min): For inum, bignum and real, if other
operand is NaN, then return NaN. Also avoid passing NaN to mpz_cmp_d.
* read.c (scm_input_error): Pass arg list parameter to scm_error_scm,
rather than SCM_EOL. Needed by "Unknown # object" case in scm_lreadr.
2003-06-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
* __scm.h, gc-card.c (SCM_DEBUG_DEBUGGER_SUPPORT,
SCM_DEBUG_DEBUGGING_SUPPORT): Renamed macro
SCM_DEBUG_DEBUGGER_SUPPORT to SCM_DEBUG_DEBUGGING_SUPPORT and
generalized it to apply not only to C level functions but also to
scheme level functions.
* debug.c, debug.h, eval.c (make-iloc, scm_make_iloc, iloc?,
scm_iloc_p, dbg-make-iloc, scm_dbg_make_iloc, dbg-iloc?,
scm_dbg_iloc_p): Moved functions scm_make_iloc, scm_iloc_p to
eval.c, made them available under SCM_DEBUG_DEBUGGING_SUPPORT == 1
only and renamed them to scm_dbg_make_iloc, scm_dbg_iloc_p,
respectively.
* deprecated.h, eval.c, eval.h (SCM_ILOC00, SCM_IDINC,
SCM_IDSTMSK): Deprecated. The macro definitions are moved from
eval.h into eval.c and a copy is placed into deprecated.h.
* eval.c, eval.h (SCM_MAKE_ILOC): Removed from eval.h and placed
into eval.c. This definition was not part of the API in any
officially released version of guile and thus does not need to go
through a phase of deprecation.
2003-06-02 Dirk Herrmann <D.Herrmann@tu-bs.de>
* deprecated.c, deprecated.h, eval.c, eval.h (scm_s_expression,
scm_s_test, scm_s_body, scm_s_bindings, scm_s_variable,
scm_s_clauses, scm_s_formals): Deprecated. In eval.c the
definitions are make static and renamed from scm_s_xxx to s_xxx.
In deprecated.c the original definitions are copied.
* deprecated.h, eval.c, eval (SCM_EVALIM2, SCM_EVALIM, SCM_XEVAL,
SCM_XEVALCAR): Deprecated. The macro definitions are moved from
eval.h into eval.c and a copy (slightly modified to work in user
code) is placed into deprecated.h.
* eval.c: Use the local static s_xxx definitions instead of the
scm_s_xxx definitions throughout.
2003-06-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
This set of patches separates the representation of the cxr family
of functions (car, cdr etc.) from the dsubr family of functions
(i. e. functions that take a double precision floating point
argument). Further, the algorithm for handling the cxr function
is improved.
* eval.c (SCM_CEVAL, SCM_APPLY, scm_trampoline_1), numbers.c
(scm_asinh, scm_acosh, scm_atanh, scm_truncate, scm_round, floor,
ceil, sqrt, fabs, exp, log, sin, cos, tan, asin, acos, atan, sinh,
cosh, tanh), objects.c (scm_class_of), procprop.c
(scm_i_procedure_arity), ramap.c (scm_array_map_x), tags.h
(scm_tc7_dsubr, scm_tcs_subrs): Introduce scm_tc7_dsubr as new
typecode for the dsubr family of functions.
* ramap.c (ramap_cxr, ramap_dsubr): Renamed ramap_cxr to
ramap_dsubr.
* eval.c (SCM_CEVAL, SCM_APPLY, call_cxr_1), pairs.c
(scm_init_pairs): Make use of the (now usable) second cell element
of a scm_tc7_cxr function to implement the cxr family of functions
more efficiently.
2003-05-31 Dirk Herrmann <D.Herrmann@tu-bs.de>
* eval.c (SCM_CEVAL, SCM_APPLY, scm_trampoline_0,
scm_trampoline_1, scm_trampoline_2): Postpone error cases to the
end of an if-else-if-sequence of checks.
2003-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
* eval.c (SCM_CEVAL): Improved readability of call-with-values
execution. Generalize apply_closure to apply_proc and use that
for call-with-values.
2003-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
* eval.c (SCM_CEVAL): Avoid one level of indirection when applying
a non closure.
2003-05-30 Stefan Jahn <stefan@lkcc.org>
* posix.c (s_scm_putenv): Use the new HAVE_UNSETENV
appropriately for mingw32 hosts.
* numbers.h: Defining copysign(), isnan() and finite() to
be prefixed by a single '_' for mingw32 hosts.
2003-05-30 Kevin Ryde <user42@zip.com.au>
* numbers.c (z_negative_one): New variable.
(scm_init_numbers): Initialize it.
(scm_logcount): Use it and mpz_hamdist to count zeros for negatives.
2003-05-29 Stefan Jahn <stefan@lkcc.org>

warning.
* posix.c (s_scm_putenv): Disable use of unsetenv() for the
mingw32 build.
* modules.c (s_scm_module_import_interface): Renamed local
variable interface to _interface. Seems like 'interface'
is a special compiler directive for the mingw32 compiler.
* mkstemp.c: Provide prototype to avoid compiler warning.
* load.c (s_scm_search_path): Fixed absolute and relative
path detections for native Windows platforms.
* gc.h, threads.h: Export some more symbols using SCM_API (necessary
to build on mingw32).
* gc-freelist.c ("s_scm_map_free_list",
"s_scm_gc_set_debug_check_freelist_x"): Fixed use of FUNC_NAME.
* fports.c (fport_fill_input): Disable use of
fport_wait_for_input() on Win32 platforms.
* filesys.c (s_scm_basename): Fixed __MINGW32__ code.
* Makefile.am: Modified some rules for cross compiling.
2003-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
* eval.c (SCM_CEVAL): In case of an application, all checks for a
proper function object and the correct number of arguments are now
performed in the application part of SCM_CEVAL.
(scm_badformalsp): Removed.
2003-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
* deprecated.c (scm_read_and_eval_x): Fixed C99-ism.
2003-05-22 Mikael Djurfeldt <djurfeldt@nada.kth.se>
* num2integral.i.c (NUM2INTEGRAL): Avoid warning about conditional
always being false by inserting preprocessor conditional. (Thanks
to Bruce Korb.)
* __scm.h (SCM_STACK_PTR): New macro. (Cast argument through
(void *) in order to avoid an aliasing warning; thanks to Bruce
Korb.)
* stackchk.h (SCM_STACK_OVERFLOW_P): Use SCM_STACK_PTR.

SCM_STACK_PTR.
* threads.c (scm_threads_mark_stacks): Bugfix: Changed
thread->base --> t->base.
* eval.c (SCM_CEVAL): Don't cast argument of SCM_STACK_OVERFLOW_P.
2003-05-20 Marius Vollmer <marius.vollmer@uni-dortmund.de>

SCM_CHARS, SCM_UCHARS, SCM_LENGTH): Re-added from the release_1_6
branch. Some have been slightly rewritten.
(scm_i_object_chars, scm_i_object_length): New, to support
SCM_CHARS, SCM_UCHARS, and SCM_LENTH.
2003-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
* eval.c (scm_m_do, unmemocopy, SCM_CEVAL): Reversed order of
names and inits in the memoized code of do.
2003-05-19 Mikael Djurfeldt <djurfeldt@nada.kth.se>
* c-tokenize.lex (yyget_lineno, yyget_in, yyget_out, yyget_leng,
yyget_text, yyset_lineno, yyset_in, yyset_out, yyget_debug,
yyset_debug, yylex_destroy): Added prototypes (otherwise we'll get
a compilation error if error-on-warning is enabled).
2003-05-17 Marius Vollmer <mvo@zagadka.de>
* c-tokenize.lex: Gobble up complete lines after a '#'. This
removes preprocessor directives from the snarfage that might
otherwise confuse us. These directives appear when compiling with
"-g3", for example.
2003-05-16 Han-Wen Nienhuys <hanwen@cs.uu.nl>
* ChangeLog: add my surname
* srcprop.c (scm_finish_srcprop): use
scm_gc_register_collectable_memory()
(scm_make_srcprops): idem.
2003-05-14 Han-Wen Nienhuys <hanwen@cs.uu.nl>
* gc-malloc.c (scm_gc_register_collectable_memory): avoid
wrap-around for scm_mtrigger

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

2003-05-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
The purpose of this patch is to make guile's internal memoizers
distinguishable from memoizing macros created on the scheme level
or from user provided primitive memoizing macros. The reason is,
that the internal memoizers are the only ones that are allowed to
transform their scheme input into memoizer byte code, while all
other memoizing macros may only transform scheme code into new
scheme code.
To achieve this, a new macro type 'builtin-macro!' is introduced.
Currently, 'builtin-macro!'s are handled as memoizing macros, but
this will change when the memoizer and executor are separated.
* macros.[ch] (scm_i_makbimacro): New.
* macros.h (SCM_BUILTIN_MACRO_P): New.
* macros.c (macro_print, scm_macro_type): Support builtin-macro!s.
* eval.c, goops.c: All of guile's primitive memoizing macros are
primitive builtin-macros now.
* eval.c (scm_macroexp, SCM_CEVAL): Make sure the primitive
builtin-macros are handled equally to memoizing macros.
2003-05-04 Marius Vollmer <mvo@zagadka.de>
* throw.c (scm_ithrow): Remove "asm volatile" hack. It used to
work around a bug in GCC 2.95.2 but is now a bug in itself.
2003-05-02 Marius Vollmer <mvo@zagadka.de>
* deprecated.h (scm_rstate, scm_rng, SCM_SLOPPY_CONSP,
SCM_SLOPPY_NCONSP, scm_tc7_ssymbol, scm_tc7_msymbol,

scm_port_for_each.
(scm_port_for_each): Reimplemented using scm_c_port_for_each.
* ports.h (scm_c_port_for_each): New prototype.
2003-04-28 Mikael Djurfeldt <djurfeldt@nada.kth.se>
* eval.c (scm_m_atdispatch): Removed until actually needed. (This
macro was introduced in anticipation of GOOPS method compilation
code.)
* goops.c: Removed binding of @dispatch.
2003-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
* eval.c, goops.c (@dispatch, @slot-ref, @slot-set!): Move the
instructions that bind the macros on the scheme level back to
goops.c in order to make sure again that the bindings go into the
(oop goops) module and are not visible from the outside.
2003-04-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
* eval.c: Non functional change: Separated R5RS and non-R5RS
macros into different sections of the file and ordered the
memoizers alphabetically.
2003-04-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
* eval.c (scm_ilookup): Rewritten to improve readability.
2003-04-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
* eval.c (scm_i_call_closure_0, call_closure_1, call_closure_2):
Partially reverted patch from 2003-04-23 in oder to find a better
compromise between readability and debuggability.
2003-04-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
* eval.c, eval.h, goops.c, goops.h (scm_m_atslot_ref,
scm_m_atslot_set_x, scm_m_atdispatch): Move the declarations and
definitions of the special goops memoizers from goops.[ch] to
eval.[ch]. Hmm... it seems that scm_m_atdispatch is not used
throughout guile.
2003-04-24 Mikael Djurfeldt <mdj@kvast.blakulla.net>
* ports.c, ports.h (scm_i_port_table_mutex): New mutex.
* fports.c (scm_evict_ports): Lock/unlock scm_i_port_table_mutex.

* fports.c (scm_fdes_to_port): Ditto.
2003-04-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
This set of patches contains no functional changes, only debatable
minor stylistic ones. Still, in order to prepare a patch between
my local copy and the CVS version, I decided to submit the changes
below. Then, the patch will hopefully only contain relevant
modifications :-)
* eval.c (iqq): Added const specifier.

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

* __scm.h (SCM_DEBUG_DEBUGGER_SUPPORT): New compile-time option.
* gc.card.c (scm_gc_marked_p): Fixed compiler warning when
compiling with SCM_DEBUG==1 by moving definition behind prototype.

scm_dbg_gc_marked_p, scm_dbg_gc_get_card, scm_dbg_gc_get_bvec,
scm_t_list_cell_struct, scm_t_list_cell, scm_t_double_cell,
scm_gc_marked_p, scm_gc_get_card, scm_gc_get_bvec): Fixed
functions such that they check if the object is a non-immediate.
Further, renamed identifiers to use the scm_dbg_ prefix and made
their inclusion into the lib dependent of the
SCM_DEBUG_DEBUGGER_SUPPORT compile time option.
2003-04-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
* __scm.h: Fixed comment about the SCM_DEBUG_TYPING_STRICTNESS
debug option.

(gen-scmconfig.$(OBJEXT)): new target - be careful to handle
cross-compiling right.
(scmconfig.h): build scmconfig.h from gen-scmconfig's output.
(BUILT_SOURCES): add scmconfig.h.
2003-03-19 Marius Vollmer <mvo@zagadka.de>
* gc_os_dep.c: Added defines for sparc-unknown-netbsdelf1.5 from
Adrian Bunk. Thanks!
2003-03-19 Mikael Djurfeldt <djurfeldt@nada.kth.se>
* goops.c (make_class_from_template): New fourth arg:
applicablep.
(scm_class_extended_generic_with_setter, scm_class_self): Fixed
cpls.
* smob.c (scm_set_smob_apply): Call scm_i_inherit_applicable.
* goops.c, objects.c, objects.h (scm_make_extended_class): New
second arg: applicablep.
(scm_i_inherit_applicable): New function.
* goops.c, goops.h (scm_class_applicable,
scm_class_extended_accessor): New classes.
2003-03-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
* procs.c (scm_procedure_documentation): Removed redundant
SCM_NIMP test and replaced other calls to SCM_IMP by more explicit
predicates.
2003-03-11 Mikael Djurfeldt <djurfeldt@nada.kth.se>
* list.c, list.h (scm_filter, scm_filter_x): New functions.
* modules.c (scm_module_import_interface): New function.
* goops.c, goops.h (scm_class_accessor_method): Renamed from
scm_class_accessor.
(scm_class_accessor): New class.
2003-03-06 Mikael Djurfeldt <djurfeldt@nada.kth.se>
* goops.c (scm_primitive_generic_generic): Enable primitive
generic if not enabled.
(scm_sys_goops_loaded): Setup unextended primitive generics.
* goops.c, goops.h (scm_c_extend_primitive_generic): New function.
* snarf.h (SCM_PRIMITIVE_GENERIC, SCM_PRIMITIVE_GENERIC_1): New
snarf macros.
* numbers.c (scm_abs): Use SCM_PRIMITIVE_GENERIC. (This is only a
testing example. All uses of SCM_GPROC should be converted.)
* procprop.c (scm_stand_in_scm_proc): Use scm_assq instead of
scm_assoc.
* eq.c (scm_equal_p): Turned into a primitive generic.
2003-02-27 Rob Browning <rlb@defaultvalue.org>
* Makefile.am (scmconfig.h): new target -- generate file from
../config.h.
(modinclude_HEADERS): remove version.h.
(nodist_modinclude_HEADERS): add version.h.
2003-02-24 Mikael Djurfeldt <djurfeldt@nada.kth.se>
This fixes a serious GC bug, introduced during the latest
reorganization of the GC, which disabled freeing of structs and
GOOPS objects:
* struct.c (scm_struct_prehistory): Init scm_i_structs_to_free to
SCM_EOL.
(scm_struct_prehistory): Move scm_free_structs to
scm_before_mark_c_hook.
* gc-card.c (sweep_card): Check that we haven't swept structs on
this card before. That can happen if scm_i_sweep_all_segments has
been called from some other place than scm_igc.
2003-02-19 Mikael Djurfeldt <djurfeldt@nada.kth.se>
* environments.c (DEFAULT_OBARRAY_SIZE): Changed from 137 to 31
(since hash tables now adapt their size).
* modules.c (scm_modules_prehistory): Changed from 2001 to 1533
(current number of prehistory bindings; hashtable code will select
a prime which is greater than this value).
* symbols.c (scm_symbols_prehistory): Changed from 1009 to 2139
(current number of initial symbols).
* properties.c (scm_init_properties): Don't specify size of
scm_properties_whash.
* objprop.c (scm_init_objprop): Don't specify size of
scm_object_whash.
* keywords.c (scm_init_keywords): Don't specify a hash table size.
* hooks.c (scm_c_hook_add): Fixed bug in append mode.
The following changes introduce the use of resizable hash tables
throughout Guile. It also renames the old *-hash-table* functions
to *-alist-vector* and places them, together with the rest of the
weak vector support, in the module (ice-9 weak-vector). We should
probably introduce a new, better, API for weak references, for
example "weak pairs" a la MIT-Scheme. (In Chez scheme, they even
look like and are used like ordinary pairs.)
* environments.c (obarray_enter, obarray_retrieve, obarray_remove,
leaf_environment_fold, obarray_remove_all): Use hashtable
accessors.
* gc.c (scm_init_storage): Moved hook initialization to
scm_storage_prehistory.
(scm_storage_prehistory): New function.
(scm_igc): Added commentary about placement of
scm_after_sweep_c_hook.
* gc-mark.c (scm_mark_all): Use hashtable accessors.
(scm_gc_mark_dependencies): Use SCM_WVECT_WEAK_KEY_P and
SCM_WVECT_WEAK_VALUE_P.
* hashtab.c, hashtab.h (scm_hash_for_each, scm_hash_map): New
functions.
(scm_vector_to_hash_table, scm_c_make_resizing_hash_table):
Removed.
(scm_make_weak_key_hash_table, scm_make_weak_value_hash_table,
scm_make_doubly_weak_hash_table): Moved here from weaks.c.
* init.c (scm_init_guile_1): Removed call to scm_init_weaks; Added
calls to scm_storage_prehistory and scm_hashtab_prehistory.
* modules.c (module-reverse-lookup): Use hashtable accessors.
* symbols.c, symbols.h (scm_i_hash_symbol): New function.
* weaks.c, weaks.h (scm_make_weak_key_alist_vector,
scm_make_weak_value_alist_vector,
scm_make_doubly_weak_alist_vector): New functions.
* weaks.c (scm_init_weaks_builtins): New function.
* weaks.h (SCM_WVECTF_WEAK_KEY, SCM_WVECTF_WEAK_VALUE,
SCM_WVECTF_NOSCAN, SCM_WVECT_WEAK_KEY_P, SCM_WVECT_WEAK_VALUE_P,
SCM_WVECT_NOSCAN_P): New macros.
* weaks.c (scm_scan_weak_vectors): Use SCM_WVECT_WEAK_KEY_P
and SCM_WVECT_WEAK_VALUE_P.
* weaks.c, weaks.h (scm_i_allocate_weak_vector): Renamed from
allocate_weak_vector and exported.
2003-02-13 Mikael Djurfeldt <djurfeldt@nada.kth.se>
* hashtab.c: Undid thread safety. (We decided that it's better to
let the user explicitly protect the tables (or not) according what
is suitable for the application.)
2003-02-12 Mikael Djurfeldt <djurfeldt@nada.kth.se>
* hashtab.c (scm_hash_fn_remove_x, scm_internal_hash_fold): Made
thread safe and handle resizing tables.
(scm_ihashx, scm_sloppy_assx, scm_delx_x): Removed
SCM_DEFER/ALLOW_INTS.
2003-02-11 Mikael Djurfeldt <djurfeldt@nada.kth.se>
* hashtab.c (scm_vector_to_hash_table,
scm_c_make_resizing_hash_table, scm_make_hash_table): New
functions.
(scm_hash_fn_get_handle, scm_hash_fn_create_handle_x): Made thread
safe and handle resizing tables.
* weaks.c (scm_make_weak_key_hash_table,
scm_make_weak_value_hash_table, scm_make_doubly_weak_hash_table):
Size argument made optional. Return resizable table if not
specified.
2003-02-10 Mikael Djurfeldt <djurfeldt@nada.kth.se>
* eval.c (scm_trampoline_0, scm_trampoline_1, scm_trampoline_2):
Fixed formals tests for closures. (Thanks to Kevin Ryde.)
2003-02-05 Mikael Djurfeldt <djurfeldt@nada.kth.se>
* debug.c (scm_procedure_source): Handle all objects for which
procedure? is #t. (Thanks to Bill Schottstaedt.)
2003-01-23 Mikael Djurfeldt <djurfeldt@nada.kth.se>
* futures.c (mark_futures): Don't need to mark data of recycled
futures.
(scan_futures, cleanup_undead): Be smarter about marking
futures---avoid unnecessary passes through future lists.
* futures.h, futures.c: New files; Introduced recycling of
futures. For fine-grained threading this lifts performance to
another level. We can now use parallelization in inner loops of
Guile programs without impossible overhead.
* threads.h, threads.c: Moved futures to their own file.
* Makefile.am (libguile_la_SOURCES): Added futures.c.
(DOT_X_FILES): Added futures.x.
(DOT_DOC_FILES): Added futures.doc.
(modinclude_HEADERS): Added futures.h.
* threads.c, threads.h (scm_i_create_thread): Renamed from
create_thread and made global.
* futures.c (scm_make_future): New procedure.
* eval.c: #include "libguile/futures.h".
* init.c: #include "futures.h"
(scm_init_guile_1): Call scm_init_futures.
* stime.c (SCM_TIME_UNITS_PER_SECOND): Renamed from CLKTCK.
* stime.h (SCM_TIME_UNITS_PER_SECOND): Definition moved here.
* eval.c, eval.h (scm_trampoline_0, scm_i_call_closure_0): New
functions.
* eval.c (scm_trampoline_1): Fixed arguments test for closures.
2003-01-22 Mikael Djurfeldt <djurfeldt@nada.kth.se>
* threads.c (create_thread): Don't unwind dynwind chain of parent
thread before creation. Just start the new thread with an empty
dynwind chain.
2003-01-20 Mikael Djurfeldt <djurfeldt@nada.kth.se>
* evalext.c, evalext.h (scm_self_evaluating_p): New function.
2003-01-10 Mikael Djurfeldt <djurfeldt@nada.kth.se>
* threads.c (scm_timed_wait_condition_variable): Support timed
waiting also for simple condition variables.
* goops.c (TEST_CHANGE_CLASS): Use scm_change_object_class instead
of calling the procedure change-object-class.
2003-01-09 Mikael Djurfeldt <djurfeldt@nada.kth.se>
* ramap.c (scm_ramapc): Typo in error message.
2003-01-08 Mikael Djurfeldt <djurfeldt@nada.kth.se>
* goops.c (scm_sys_prep_layout_x): Bugfix: Only create layout for
slots with instance allocation.
* goops.c, goops.h (scm_class_extended_generic_with_setter): New
class.
(scm_compute_applicable_methods): Use scm_generic_function_methods.
* goops.c (scm_generic_function_methods): Support extended
generic functions.
2002-12-29 Mikael Djurfeldt <djurfeldt@nada.kth.se>
* eval.c (unmemocopy): Bugfix: scm_sym_delay --> scm_sym_future.
Thanks to Neil for pointing this out!
2002-12-29 Neil Jerram <neil@ossau.uklinux.net>
* lang.h: Remove declarations matching definitions removed from
lang.c (just below).
2002-12-28 Neil Jerram <neil@ossau.uklinux.net>
* lang.c (scm_nil_cons, scm_nil_car, scm_nil_cdr, scm_null,
scm_m_while, scm_nil_eq): Remove definitions that were superfluous
and already commented out.
* read.h (scm_lreadparen), read.c (scm_lreadr, scm_read_token,
scm_lreadparen): Support reading vectors with Elisp syntax if
SCM_ELISP_READ_EXTENSIONS is defined. (SCM_ELISP_READ_EXTENSIONS
is not currently defined, and there isn't even a configure switch
to enable it yet.)
2002-12-26 Marius Vollmer <mvo@zagadka.ping.de>
* Makefile.am (c-tokenize.o): Refer to source via $< so that vpath
builds work.
(EXTRA_DIST): Added version.h.in.
2002-12-21 Mikael Djurfeldt <djurfeldt@nada.kth.se>
This change makes it possible for one thread to do lazy sweeping
while other threads are running. Now only the mark phase need to
have all threads asleep. We should look further into this issue.
Presently, I've put the locking of scm_i_sweep_mutex at
"conservative" places due to my current lack of knowledge about
the garbage collector. Please feel free to restrict these regions
further to allow for maximal parallelism!
* gc.c, gc.h (scm_i_sweep_mutex): New mutex.
* gc.c (scm_gc_for_newcell), gc-malloc.c (scm_realloc,
scm_gc_register_collectable_memory): Substitute locking of
scm_i_sweep_mutex for calls to scm_i_thread_put_to_sleep.
(scm_igc): Lock sweep mutex here instead of in callers; Calls to
scm_i_thread_put_to_sleep/scm_i_thread_wake_up used to demarkate
the single-thread section (which now only contains the mark
phase).
(scm_gc): Don't lock sweeo mutex here since scm_igc locks it;
Removed SCM_DEFER/ALLOW_INTS. Simply call scm_igc directly.
* threads.c (gc_section_mutex): Removed.
2002-12-19 Mikael Djurfeldt <mdj@kvast.blakulla.net>
* threads.c (create_thread): Clear parent field in root state in
order not to unnecessarily remember dead threads.
* eval.c (call_subr2o_1, call_lsubr2_2): New functions.
(scm_trampoline_1, scm_trampoline_2): Use them.
2002-12-18 Mikael Djurfeldt <mdj@kvast.blakulla.net>
Partial introduction of real plugin interface.
* Makefile.am (modinclude_HEADERS): Added threads-plugin.h.
(EXTRA_DIST): Added threads-plugin.c.
* threads-plugin.h, threads-plugin.c: New files.
* threads.h: #include "libguile/threads-plugin.h".
* threads.c: #include "libguile/threads-plugin.c".
* pthread-threads.c: Temporarily remove debugging functions.
* threads.c, threads.h (scm_yield): Added back.
2002-12-18 Mikael Djurfeldt <mdj@kvast.blakulla.net>
* threads.c (really_launch): Detach before unlocking
thread_admin_mutex in order not to risk being joined.
(scm_i_thread_put_to_sleep, scm_i_thread_wake_up): Keep
thread_admin_mutex locked during GC.
* pthread-threads.c, pthread-threads.h: Improvements to debugging
functions.
2002-12-16 Mikael Djurfeldt <mdj@kvast.blakulla.net>
* pthread-threads.c, pthread-threads.h (SCM_DEBUG_THREADS): Added
support for debugging mutex operations.
* threads.c (scm_thread): Removed filed joining_threads.
(thread_print): Print thread number as well as address of thread
structure.
(scm_join_thread): Bugfix.
(scm_lock_mutex, scm_try_mutex, scm_unlock_mutex,
scm_timed_wait_condition_variable, scm_signal_condition_variable,
scm_broadcast_condition_variable): Use the low-level API.
(scm_all_threads): Return copy of thread list (to prevent
unintended destruction).
(scm_threads_prehistory): Initialize heap_mutex of fake thread.
* pthread-threads.c, pthread-threads.h, threads.c: Fixes to
pthread "native" recursive mutex support.
2002-12-15 Mikael Djurfeldt <djurfeldt@nada.kth.se>
* __scm.h (SCM_DEFER_INTS, SCM_ALLOW_INTS): New definitions.
Simply lock a thread C API recursive mutex.
(SCM_NONREC_CRITICAL_SECTION_START,
SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START,
SCM_REC_CRITICAL_SECTION_END): Removed.
* eval.c: Replaced SOURCE_SECTION_START / SOURCE_SECTION_END with
direct calls to scm_rec_mutex_lock / unlock around the three calls
to scm_m_expand_body.
* eval.c, eval.h (promise_free): New function.
(scm_force): Rewritten; Now thread-safe; Removed
SCM_DEFER/ALLOW_INTS.
* pthread-threads.h: Added partially implemented plugin interface
for recursive mutexes. These are, for now, only intended to be
used internally within the Guile implementation.
* pthread-threads.c: New file.
* threads.c: Conditionally #include "pthread-threads.c".
* eval.c, eval.h (scm_makprom, scm_force): Rewritten to be
thread-safe;
* snarf.h (SCM_MUTEX, SCM_GLOBAL_MUTEX, SCM_REC_MUTEX,
SCM_GLOBAL_REC_MUTEX): New macros.
* eval.c, threads.c, threads.h, snarf.h: Rewrote critical section
macros---use mutexes instead.
* tags.h (SCM_IM_FUTURE): New tag.
* eval.c (scm_m_future): New primitive macro.
(SCM_CEVAL): Support futures.
(unmemocopy): Support unmemoization of futures.
* print.c (scm_isymnames): Name of future isym.
* version.c: Unmade some changes to my private copy that got
committed by mistake.
2002-12-11 Mikael Djurfeldt <mdj@kvast.blakulla.net>
* gc-malloc.c, gc.h, init.c: Reverted gc-malloc change of
2002-12-10.
* gc.c (scm_igc): Don't call scm_i_thread_invalidate_freelists.
* gc.c (scm_gc_sweep): Call it here instead, which is a more
logical place.
* threads.c (create_thread): Remember root object until the handle
of the new thread is on all_threads list.
* root.c (scm_make_root): Moved copying of fluids until after
creation of root handle so that the fluids are GC protected. Also
removed the critical section.
2002-12-10 Mikael Djurfeldt <mdj@kvast.blakulla.net>
* gc-malloc.c, gc.h (scm_gc_malloc_prehistory): New function.
* gc-malloc.c (malloc_mutex): New mutex.
(scm_gc_malloc_prehistory): Initialize it.
(scm_realloc): Serialize call to realloc
(scm_calloc): Same for calloc.
Thanks to Wolfgang Jaehrling!
(Now we have to make sure all calls to malloc/realloc are made
through scm_malloc.)
* init.c (scm_init_guile_1): Call scm_gc_malloc_prehistory.
* threads.c (really_launch): Release heap (to prevent deadlock).
(create_thread): Release heap before locking thread admin mutex.
2002-12-10 Mikael Djurfeldt <mdj@kvast.blakulla.net>
* threads.c (scm_i_thread_invalidate_freelists): New
function.
* gc.c (scm_igc): Call scm_i_thread_invalidate_freelists.
* modules.c (scm_export): Inserted a return statement.
2002-12-10 Han-Wen Nienhuys <hanwen@cs.uu.nl>
* modules.c (scm_export): new function
* gc-card.c: add a note about malloc()/free() overhead.
2002-12-10 Mikael Djurfeldt <mdj@kvast.blakulla.net>
* Makefile.am (c-tokenize.$(OBJEXT)): Don't look for c-tokenize.c
in srcdir.
2002-12-10 Mikael Djurfeldt <djurfeldt@nada.kth.se>
These changes remove scm_ints_disabled (which hasn't has any
effect in Guile for quite some time).
* async.c, error.h (scm_ints_disabled): Removed.
* gc.c (scm_gc_for_newcell), init.c (scm_init_guile_1),
root.c (scm_internal_cwdr), gdbint.c (SCM_BEGIN_FOREIGN_BLOCK,
SCM_END_FOREIGN_BLOCK): Don't touch scm_ints_disabled.
(old_ints): Removed.
* __scm.h (SCM_DEFER_INTS, SCM_ALLOW_INTS): Define as a recursive
critical section.
(SCM_REDEFER_INTS, SCM_ALLOW_INTS): Define as SCM_DEFER_INTS and
SCM_ALLOW_INTS.
2002-12-09 Mikael Djurfeldt <djurfeldt@nada.kth.se>
* threads.c (scm_mutex_lock, scm_cond_wait, scm_cond_timedwait):
Removed accidental #if 0 around these functions.
These changes are the start of support for preemptive
multithreading. Marius and I have agreed that I commit this code
into the repository although it isn't thoroughly tested and surely
introduces many bugs. The bugs should only be exposed when using
threads, though. Signalling and error handling for threads is
very likely broken. Work on making the implementation cleaner and
more efficient is needed.
* __scm.h (SCM_ALLOW_INTS_ONLY): Removed.
(SCM_NONREC_CRITICAL_SECTION_START,
SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START,
SCM_REC_CRITICAL_SECTION_END): New macros.
(SCM_CRITICAL_SECTION_START/END): Defined here.
* eval.c: Insert SOURCE_SECTION_START / SOURCE_SECTION_END around
the three calls to scm_m_expand_body.
* gc.h: #include "libguile/pthread-threads.h";
(SCM_FREELIST_CREATE, SCM_FREELIST_LOC): New macros.
* gc.c (scm_i_freelist, scm_i_freelist2): Defined to be of type
scm_t_key;
* gc.c, gc-freelist.c, inline.h: Use SCM_FREELIST_LOC for freelist
access.
* gc-freelist.c (scm_gc_init_freelist): Create freelist keys.
* gc-freelist.c, threads.c (really_launch): Use
SCM_FREELIST_CREATE.
* gc-malloc.c (scm_realloc, scm_gc_register_collectable_memory):
* gc.c (scm_i_expensive_validation_check, scm_gc,
scm_gc_for_newcell): Put threads to sleep before doing GC-related
heap administration so that those pieces of code are executed
single-threaded. We might consider rewriting these code sections
in terms of a "call_gc_code_singly_threaded" construct instead of
calling the pair of scm_i_thread_put_to_sleep () and
scm_i_thread_wake_up (). Also, we would want to have as many of
these sections eleminated.
* init.c (scm_init_guile_1): Call scm_threads_prehistory.
* inline.h: #include "libguile/threads.h"
* pthread-threads.h: Macros now conform more closely to the
pthreads interface. Some of them now take a second argument.
* threads.c, threads.h: Many changes.
2002-12-09 Mikael Djurfeldt <djurfeldt@nada.kth.se>
* Makefile.am (version.h): Changed $^ --> $< in rule for
version.h.
2002-12-08 Rob Browning <rlb@defaultvalue.org>
* version.h.in (SCM_MICRO_VERSION): use @--@ substitution now.
(SCM_MINOR_VERSION): use @--@ substitution now.
(SCM_MICRO_VERSION): use @--@ substitution now.
(scm_effective_version): new function prototype.
* version.c (scm_effective_version): new function, also add
effective-version.
* Makefile.am (schemelibdir): VERSION -> GUILE_EFFECTIVE_VERSION.
(libpath.h): use GUILE_EFFECTIVE_VERSION to compute
SCM_LIBRARY_DIR.
(version.h): generate this here rather than configure.in. This
approach tracks source edits better (i.e. more immediately).
Might be worth considering for other .in files too.
2002-12-02 Marius Vollmer <mvo@zagadka.ping.de>
Reorganized thread package selection. A thread package now only
implements a small set of pthread like functions and Guile
implements the rest on top of that. Guile's implementation is
what the "coop-pthreads" package has been previously. Support for
"coop" threads has been removed until I get time to add it again.
* Makefile.am (libguile_la_SOURCES): Removed iselect.c.
(noinst_HEADERS): Removed coop-threads.c, coop-threads.h, coop.c,
null-threads.c, coop-pthreads.c.
(modinclude_HEADERS): Removed coop-defs.h, coop-pthreads.h. Added
pthread-threads.h.
* validate.h (SCM_VALIDATE_THREAD): Moved to threads.h.
* threads.h: Do not include "libguile/coop-defs.h". Include
"libguile/pthread-threads.h" for USE_COPT_THREADS. Removed
(previously deprecated) C level thread API prototypes. They are
now in the thread package specific headers, "null-threads.h" and
"pthread-threads.h".
(SCM_VALIDATE_THREAD, SCM_VALIDATE_MUTEX, SCM_VALIDATE_CONDVAR):
New.
(scm_threads_init): Removed.
(SCM_CRITICAL_SECTION_START, SCM_CRITICAL_SECTION_END,
SCM_THREAD_SWITCHING_CODE, scm_i_switch_counter,
SCM_I_THREAD_SWITCH_COUNT): Define here.
(scm_single_thread_p): Removed.
(scm_call_with_new_thread): Take two args directly instead of list
of two args.
(scm_i_thread_data, scm_i_set_thread_data, SCM_THREAD_LOCAL_DATA,
SCM_SET_THREAD_LOCAL_DATA): Define here.
* threads.c: Merged with "coop-pthreads.c".
* null-threads.h: Implement pthread-like API as a set of macros.
* pthread-threads.h: New, implement pthread-like API by deferring
to pthread itself.
* init.c (scm_init_guile_1): Do not call scm_init_iselect, which
has been lost in the reorganization.
2002-12-01 Mikael Djurfeldt <mdj@linnaeus>
The following change makes it possible to move procedure
application dispatch outside inner loops. The motivation was
clean implementation of efficient replacements of R5RS primitives
in SRFI-1.
The semantics is clear: scm_trampoline_N returns an optimized
version of scm_call_N (or NULL if the procedure isn't applicable
on N args).
Applying the optimization to map and for-each increases efficiency
noticeably. For example, (map abs ls) is 8 times faster than
before.
* eval.h (scm_t_trampoline_1, scm_t_trampoline_2): New types.
* eval.c, eval.h (scm_trampoline_1, scm_trampoline_2): New functions.
* eval.c (call_subr2_2, call_lsubr_2, call_closure_2): New functions;
(map, for-each): Handle also application on two args as a special
case; Use trampolines.
Other changes:
* sort.c (scm_cmp_function): Choose subr2less for scm_tc7_subr_2o;
(subr2oless): Removed.
(scm_restricted_vector_sort_x): Use scm_return_first to keep the
vector GC protected.
* eval.c (check_map_args): Use scm_out_of_range_pos instead of
scm_out_of_range.
2002-11-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
* evalext.[ch] (scm_m_undefine, undefine): Deprecated.
2002-11-17 Mikael Djurfeldt <mdj@linnaeus>
* debug.c (scm_make_iloc): Added missing "return".
2002-11-17 Marius Vollmer <mvo@zagadka.ping.de>
* strports.c (scm_eval_string_in_module): Validate second arg to
be a module. Thanks to Arno Peters!
2002-11-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
* .cvsignore: remove goops.c
2002-11-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
* modules.c (scm_env_top_level, scm_lookup_closure_module,
module_variable, scm_module_lookup_closure,
scm_module_transformer, scm_sym2var, scm_module_reverse_lookup,

* continuations.h: ia64: Include <signal.h> before
<sys/ucontext.h>.
2002-07-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
* modules.c (scm_sym2var): Don't compare SCM values with ==.
2002-07-21 Han-Wen Nienhuys <hanwen@cs.uu.nl>
* goops.c (scm_compute_applicable_methods): use
scm_remember_upto_here_1 iso scm_remember_upto_here
* macros.c: include deprecation.h
* vectors.c (scm_vector_move_right_x): remove side effect in
macro arg.
(scm_vector_move_left_x): idem.
* net_db.c, posix.c, socket.c: variable naming: change ans to
result.
* sort.c (scm_merge_vector_x): accept vector as argument
iso. SCM*. This is needed for full GC correctness.
* gc.h: undo previous undocumented changes related to #ifdef
GENGC.
2002-07-20 Han-Wen Nienhuys <hanwen@cs.uu.nl>
* *.c: add space after commas everywhere.
* *.c: use SCM_VECTOR_SET everywhere, where a vector is written.
Document cases where SCM_WRITABLE_VELTS() is used.
* vectors.h (SCM_VELTS): prepare for write barrier, and let
SCM_VELTS() return a const pointer
(SCM_VECTOR_SET): add macro.
2002-07-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
* eval.c (SCM_CEVAL), macros.c (macro_print, scm_makmacro,
scm_sym_macro, scm_macro_type), macros.h (scm_makmacro):
Deprecated the special kind of built-in dynamic syntax transformer
that was inaccurately named "macro". Note: The built-in syntax
transformers that are named "mmacro" or "memoizing-macro" still
exist, and it is these which come much closer to what one would
call a macro.
2002-07-13 Neil Jerram <neil@ossau.uklinux.net>
* eval.c (unmemocopy): Fix for
1001-local-eval-error-backtrace-segfaults (unmemoization crash
with internal definitions and local-eval).
2002-07-12 Gary Houston <ghouston@arglist.com>
* dynl.c: Don't define stub procedures if DYNAMIC_LINKING is not
defined. They don't do anything useful, especially since the
only case where DYNAMIC_LINKING is undefined seems to be
when --with-modules=no is given to configure, which is basically
requesting that the "dynamic linking module" be omitted.
* Makefile.am (libguile_la_SOURCES): move dynl.c from
libguile_la_SOURCES to EXTRA_libguile_la_SOURCES.
* extensions.c (load_extension): check DYNAMIC_LINKING for
scm_dynamic_call.
* init.c (scm_init_guile_1): check DYNAMIC_LINKING for
scm_init_dynamic_linking.
2002-07-10 Marius Vollmer <mvo@zagadka.ping.de>
* guile.c, iselect.h, net_db.c, posix.c, socket.c: No need to
check for Cygwin when including <winsock2.h>, this is already
check for by configure. Thus, revert change from 2002-07-07.
2002-07-10 Gary Houston <ghouston@arglist.com>
* eq.c: include <string.h>
* dynl.c: docstring editing.
2002-07-09 Gary Houston <ghouston@arglist.com>
* dynl.c (scm_dynamic_call): docstring editing.
2002-07-08 Rob Browning <rlb@defaultvalue.org>
* gc_os_dep.c: HURD fixes.
2002-07-07 Marius Vollmer <mvo@zagadka.ping.de>
Crosscompiling and Cygwin fixes by Jan Nieuwenhuizen. Thanks!
* Makefile.am: Override default rule for c-tokenize.$(OBJECT);
this should be compiled for BUILD host.
Override default rule for
guile_filter_doc_snarfage$(EEXECT); this should run on BUILD host.
Add missing $(EXEEXT) to guile_filter_doc_snarfage invocation.
(snarf2checkedtexi): Use GUILE_FOR_BUILD instead of preinstguile.
* guile.c, iselect.h, net_db.c, posix.c, socket.c: Do not include
<winsock2.h> on Cygwin even when we have it.
2002-07-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
* __scm.h (SCM_CAUTIOUS), eval.c (scm_eval_args, deval_args,
SCM_CEVAL): Removed compile time option SCM_CAUTIOUS to clean up
the code. Full number of arguments checking of closures is
mandatory now. However, the option to disable the checking has
most probably not been used anyway.
2002-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
* __scm.h (SCM_RECKLESS), backtrace.c (SCM_ASSERT), debug.c
(scm_debug_options), eval.c (scm_lookupcar, scm_lookupcar1,
scm_badargsp, SCM_CEVAL, SCM_APPLY, scm_map, scm_for_each),
feature.c (scm_init_feature), gsubr.c (scm_gsubr_apply), numbers.c
(scm_logand, scm_logior, scm_logxor, scm_i_dbl2big), srcprop.c
(scm_source_properties, scm_set_source_properties_x,
scm_source_property): Removed compile time option SCM_RECKLESS to
clean up the code. Full number of arguments checking of closures
is mandatory now. However, the option to disable the checking has
most probably not been used anyway.
* srcprop.c (scm_source_properties, scm_set_source_properties_x,
scm_source_property): Use !SCM_CONSP instead of SCM_NCONSP.
2002-06-30 Gary Houston <ghouston@arglist.com>
* dynl.c: Removed all SCM_DEFER_INTS/SCM_ALLOW_INTS, which won't
do anything useful. Added a comment about need for a mutex if
pre-emptive threading is supported.
* posix.c (scm_convert_exec_args), dynl.c
(scm_make_argv_from_stringlist): static procs: 1) renamed both to
allocate_string_pointers. 2) simplified: don't reallocate the
strings, just make an array of pointers 3) avoid memory leaks on
error 4) let the procedure report errors in its own name.
Consequences: 1) the procedures now assume that SCM strings are
nul-terminated, which should always be the case. 2) Since strings
are not reallocated, it's now possible for strings passed to
dynamic-args-call to be mutated.
2002-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
* __scm.h, eval.c, eval.h: Removed compile time option
MEMOIZE_LOCALS to clean up the code. Now, caching of local
variable positions during memoization is mandatory. However, the
option to disable the caching has most probably not been used
anyway.
2002-06-18 Marius Vollmer <mvo@zagadka.ping.de>
* print.c (scm_simple_format): Print missing part of format before
~% control. Thanks to Daniel Skarda!
2002-06-01 Marius Vollmer <mvo@zagadka.ping.de>
* mkstemp.c: Added exception notice to license statement.
2002-05-22 Marius Vollmer <mvo@zagadka.ping.de>
* numbers.c (mem2ureal): When returning an inexact zero, make sure
it is represented as a floating point value so that we can change
its sign.
From John W. Eaton <jwe@bevo.che.wisc.edu>
* numbers.c (idbl2str): Don't omit sign when printing negative zero.
2002-05-14 Thien-Thi Nguyen <ttn@giblet.glug.org>
* gc_os_dep.c: For I386/OPENBSD, allow for `__i386__'
in addition to `i386'. Thanks to Dale P. Smith.
2002-05-08 Marius Vollmer <mvo@zagadka.ping.de>
* eq.c (real_eqv): New.
(scm_eqv_p): Use it when comparing reals and complexes.
* numbers.c: Include <string.h>, for strncmp.
(mem2complex): Do not create negative NaNs.
(scm_leq_p, scm_geq_p): Explicitely return #f when comparing a
NaN.
(scm_inexact_to_exact): Signal error when converting a NaN.
2002-05-06 Marius Vollmer <mvo@zagadka.ping.de>
* posix.c (scm_putenv): Handle removing variables explicitely by
calling unsetenv.
From John W. Eaton.
* numbers.h: Conditionally include floatingpoint.h, ieeefp.h, and
nan.h. Provide declarations for scm_inf_p, scm_nan_p, scn_inf,
and scm_nan.
* numbers.c: [SCO && ! HAVE_ISNAN] (isnan): New function.
[SCO && ! HAVE_ISINF] (isinf): New function.
(xisinf, xisnan): New functions.
(IS_INF): Delete.
(isfinite): Define in terms of xisinf.
(scm_inf_p, scm_nan_p): New functions.
(guile_Inf, guile_NaN): New file-scope vars.
(guile_ieee_init): New function.
(scm_inf, scm_nan): New functions.
(idbl2str): Handle Inf and NaN. Remove funny label and
corresponding gotos.
(ALLOW_DIVIDE_BY_ZERO): New macro.
(scm_divide): Allow division by zero to occur if
ALLOW_DIVIDE_BY_ZERO is defined.
Handle bignums and ints as special cases.
Additional stuff by me:
numbers.c (mem2ureal): Recognize "inf.0" and "nan.xxx".
(scm_even_p, scm_odd_p): Treat infinity as even and odd.
(iflo2str): Don't output a '+' for negative numbers or for Inf and
NaN. They will provide their own sign.
(scm_divide): Only allow divides by inexact zeros. Dividing by
exact zeros still signals an errors.
2002-04-22 Thien-Thi Nguyen <ttn@giblet.glug.org>
* goops.h (scm_slot_exists_p): Rename from scm_slots_exists_p.
* goops.c (scm_slot_exists_p): Rename from scm_slots_exists_p.
(scm_slot_exists_p): Rename from scm_slots_exists_p.
Thanks to Andreas Rottmann.
2002-04-20 Gary Houston <ghouston@arglist.com>

Cramer for pointing out the disuse.)
* root.h (scm_root_state): removed def_inp, def_outp, def_errp.
(scm_def_inp, scm_def_outp, scm_def_errp): removed.
* root.c (root_mark): don't mark them.
(scm_make_root): don't set them to #f.
* init.c (scm_init_standard_ports): don't initialise with the
default ports.
2002-04-17 Marius Vollmer <mvo@zagadka.ping.de>
* Makefile.am (EXTRA_DIST): Added cpp_err_symbols.c and
cpp_sig_symbols.c.
2002-04-16 Marius Vollmer <mvo@zagadka.ping.de>
* guile-snarf.in: Do not clean input file. This would write to
the $(srcdir) during a VPATH build, which is not allowed. It also
isn't needed since it only works when an output filename has been
specified and in that case we don't need to clean the input file
because the output file will already exist.
2002-03-31 Marius Vollmer <mvo@zagadka.ping.de>
* guile-snarf: Install the trap for removing $cleanfile only when
the value of $cleanfile is actually known.
2002-04-10 Rob Browning <rlb@defaultvalue.org>
* .cvsignore: add versiondat.h and *.c.clean.c.
2002-03-26 Dirk Herrmann <D.Herrmann@tu-bs.de>

function, replaces macro SRCBRKP.
(SRCBRKP): Deprecated.
* eval.c (SCM_CEVAL): Replaced use of SRCBRKP by call to
scm_c_source_property_breakpoint_p. Removed some use of arg1 as
temporary variable.
2002-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
* debug.h, eval.c: Deprecated CHECK_ENTRY, CHECK_APPLY and
CHECK_EXIT and removed all references to them.
2002-03-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
* debug.h (scm_ready_p, debug_print): Removed declarations.
* eval.c (EVALCELLCAR): Removed.
(SCM_CEVAL): Eliminated label loopnoap. Removed side-effecting
operation from condition.
2002-03-24 Marius Vollmer <mvo@zagadka.ping.de>
* guile-snarf.in: When the output filename is "-", write to
stdout. When no "-o" option is given, use "-" as the output
filename (i.e., stdout). Only 'clean' the inputfile or remove the
output file on error when the output file name is not "-". Define
the preprocessor macro SCM_MAGIC_SNARFER while snarfing.
* Makefile.am (.c.x): Pass "-o $@" to guile-snarf.
2002-03-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
* eval.c (SCM_CEVAL, SCM_APPLY): Eliminated labels wrongnumargs
and the corresponding goto statements. Removed redundant code.
2002-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
* eval.c (SCM_CEVAL): Minimized scope of variable arg2.
Eliminated redundant SCM_IMP check. Exlined call to EVALCAR.
Re-enabled handing of rpsubrs and asubrs.
2002-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
* eval.c (SIDEVAL): Removed.
(SCM_CEVAL): Minimized scope of variable orig_sym. Eliminated
goto-labels cdrxnoap, cdrxbegin and nontoplevel_cdrxnoap. Changed
argument checking order for set! to locals, variables and symbols.
Improvements to control structure. Removed some uses of arg1 and
arg2 as temporary variables.
2002-03-15 Thien-Thi Nguyen <ttn@giblet.glug.org>
* guile-snarf.in: Remove "--compat=1.4" support.
Add "-d" and "-D" support.
(deprecated_list): New var.
(compat_mode_clean_xxx): Delete.
(grep_deprecated): New func.
("main"): If "-d" or "-D", call `grep_deprecated'.
2002-03-15 Neil Jerram <neil@ossau.uklinux.net>
* hooks.h: Change scm_t_c_hookype_t everywhere to
scm_t_c_hook_type.
Docstring fixes:
* strings.c (scm_string_p): Change unnecessary `iff' to `if'.
* ports.c (scm_sys_make_void_port): Use `@file'.
* numbers.c (scm_number_p, scm_real_p): Use `otherwise' rather
than `else'.
* macros.c (scm_makmacro): Don't say that the form replaces its
source, because it doesn't.
(scm_makmmacro): Clarify difference between this and scm_makmacro.
* backtrace.c (scm_display_error), filesys.c (scm_umask,
scm_select, scm_basename), goops.c (scm_method_generic_function),
numbers.c (scm_integer_length), posix.c (scm_getgroups, scm_execl,
scm_setlocale, scm_flock), socket.c (scm_shutdown): Correct
spelling mistakes.
* debug.c (scm_debug_options), eval.c
(scm_eval_options_interface), read.c (scm_read_options): Change
incorrect @var in docstring to @code.
2002-03-14 Marius Vollmer <mvo@zagadka.ping.de>
* unif.c (singp): Use SCM_REALP instead of SCM_SLOPPY_REALP.
* snarf.h (SCM_SNARF_INIT): Add "^:^" after code so that
guile-snarf can remove trailing non-init code.
* guile-snarf.in (modern_snarf): Remove everything following and
including "^:^" from the output.
2002-03-14 Dirk Herrmann <D.Herrmann@tu-bs.de>
* eval.c (SCM_CEVAL), srcprop.h (SRCBRKP): Eliminated union 't'.
* eval.c (SCM_CEVAL): Exlined call to EVALCAR.
2002-03-13 Thien-Thi Nguyen <ttn@giblet.glug.org>
* guile-snarf.in: Update copyright.
Rewrite to internalize error handling.
Add "--compat=1.4" handling.
Add commentary.
* Makefile.am (libpath.h): Use @top_srcdir_absolute@.
(snarfcppopts): New var.
(.c.x): Use $(snarfcppopts). Rework guile-snarf usage.
(.c.doc): Use $(snarfcppopts).
* alist.c, arbiters.c, async.c, backtrace.c, boolean.c, chars.c,

2002-03-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
* eval.c (SCM_CEVAL): Got rid of the last reference to t.lloc.
The next step will be to remove the union 't' and simplify the
code of SCM_CEVAL that way.
2002-03-12 Neil Jerram <neil@ossau.uklinux.net>
* iselect.c (collisionp, gnfds, greadfds, gwritefds, gexceptfds,
rreadfds, rwritefds, rexceptfds): Made static.

hopefully descriptive names for clarification. Replaced SCM_N?IMP
by a more explicit predicate in some places.
2002-03-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
* eval.c (SCM_CEVAL): Cleaned up the handling of #@dispatch.
Added lots of comments regarding the implementation of #@dispatch.
Changed intra-procedure communication to use t.arg1 instead of
arg2. Removed some uses of t.arg1, t.lloc and proc as temporary
variables. Introduced temporary variables with hopefully
descriptive names for clarification. Replaced SCM_N?IMP by a more
explicit predicate in some places. Use SCM_INSTANCE_HASH instead
of computing the expression explicitly. Eliminate now unused
label nontoplevel_cdrxbegin.
* goops.h (SCM_INSTANCE_HASH): New macro.
* objects.h (SCM_CMETHOD_FORMALS, SCM_CMETHOD_BODY): New macros.
2002-03-08 Thien-Thi Nguyen <ttn@giblet.glug.org>

"guile-snarf" moved back from `noinst_SCRIPTS'.
2002-03-08 Neil Jerram <neil@ossau.uklinux.net>
* srcprop.c (scm_set_source_property_x): If SRCPROPS obj already
exists when adding a source property other than those that are
handled explicitly, add the new property to the SRCPROPS obj's
plist.
* debug.h (SCM_MAX_FRAME_SIZE): Remove incorrect comment about use
of SCM_MAX_FRAME_SIZE as a bit mask; it isn't used like this.
* eval.c (SCM_CEVAL): Don't store scm_debug_eframe_size in
debug.status. It isn't needed, and it can overflow the bits
reserved for it (which may lead to a segv or a GC abort).
2002-03-02 Dirk Herrmann <D.Herrmann@tu-bs.de>
* eval.c (SCM_CEVAL): Cleaned up the handling of 'apply'. Removed
side-effecting operations from conditions and macro calls.
Replaced SCM_N?IMP by a more explicit predicate in some places.
Minimized the scope of some variables.
2002-03-02 Stefan Jahn <stefan@lkcc.org>
* convert.i.c: Fixed int <-> long conversions which would have
failed if their sizes were different.
2002-03-02 Dirk Herrmann <D.Herrmann@tu-bs.de>
* eval.c (SCM_CEVAL): Cleaned up the handling of 'if', 'let',
'letrec' and 'set*': Removed some uses of t.arg1, t.lloc and proc
as temporary variables. Removed side-effecting operations from
conditions and macro calls. Introduced temporary variables with
hopefully descriptive names for clarification. Replaced SCM_N?IMP
by a more explicit predicate in some places. Removed code that
was conditionally compiled if SICP was defined - which it never
is.
2002-03-02 Dirk Herrmann <D.Herrmann@tu-bs.de>

(noinst_PROGRAMS, noinst_SCRIPTS): New.
2002-02-11 Marius Vollmer <marius.vollmer@uni-dortmund.de>
* gc.h, gc.c (scm_gc_sweep): Issue deprecation warning when
non-zero is returned from a port or smob free function.
(scm_malloc, scm_realloc, scm_strndup, scm_strdup,

Change @deffnx lines in docstrings to say {Scheme Procedure}
rather than primitive or procedure.
* posix.c (scm_execl), filesys.c (scm_close), unif.c

* objprop.c (scm_object_properties, scm_set_object_properties_x,
scm_object_property, scm_set_object_property_x): Remove invalid
@deffnx lines for corresponding procedure property primitives.
These changes add a @deffnx C function declaration and function
index entries for each Guile primitive to the copy of the doc
snarf output that is used for reference manual synchronization.
Online help is unchanged.

once to produce guile.texi for reference manual synchronization.
2001-11-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
* eval.c (RETURN): Wrap in do{}while(0) in order to make it
safely usable as a single statement followed by a ';', for example
in an if statement.

symbols.
* strop.h, strop.c (scm_substring_move_left_x,
scm_substring_move_right_x): Removed.
* __scm.h (HAVE_UINTPTR_T, HAVE_PTRDIFF_T, HAVE_LONG_LONG,
HAVE_LONG_LONGS): Define to "1" when defining them, to mirror what
configure does.
2001-11-12 Marius Vollmer <mvo@zagadka.ping.de>
* numbers.c: Document macros to define when including
num2integral.i.c. MAX_VALUE and MIN_VALU are no longer used, we
now rely on SIZEOF_ macros that have been figured out at
configure time.
* num2integral.i.c: Adapt to new interface.
(NUM2INTEGRAL): Test whether a fixnum can be represented in the
target type by casting it and checking whether it is still the
same. Do not try to handle bignums for integral types that are
smaller than fixnums. When handling bignums, collect the
magnituse first into a unsigned type, and correctly check for
overflow.
(INTEGRAL2BIG): Do not use MIN_VALUE explicitely by observing that
only -MIN_VALUE can still be negative of all negative numbers (in
twos-complement).
* tags.h (SIZEOF_SCM_T_BITS): Define it appropriately.
* __scm.h: Define HAVE_UINTPTR_T, HAVE_PTRDIFF_T and
HAVE_LONG_LONG depending on whether their size is non-zero.

lines.
* filesys.c (scm_select), guardians.c (scm_guardian_greedy_p),
strings.c (scm_make_string), variable.c (scm_make_variable,
scm_make_undefined_variable, scm_variable_p, scm_variable_set_x,

(scm_hash_fold), ports.c (scm_port_for_each): Remove superfluous
newline at end of docstrings.
* modules.c (scm_set_current_module): Add missing newline to
docstring.
2001-11-07 Stefan Jahn <stefan@lkcc.org>
* win32-socket.[ch]: New files. Defines Winsock-API error codes
and makes them available through Guile. That is because the
Winsock-API does not store its errors in `errno' and thus cannot
return error messages via `strerror (errno)'.
* socket.c (scm_init_socket): Initialize `win32-socket' part
here under M$-Windows.
* numbers.h: Added missing declaration of
`scm_sys_check_number_conversions()'.

and use in `(strerror)' and `(system-error)'.
* Makefile.am (EXTRA_libguile_la_SOURCES): Added
`win32-socket.[ch]' to extra source and header files.
2001-11-06 Marius Vollmer <mvo@zagadka.ping.de>
* script.c (scm_shell_usage, scm_compile_shell_switches): Prepend
a call to turn-on-debugging when --debug has been given instead of
turning it on directly. Also, handle new `--no-debug' option,
which might suppress the call to turn-on-debugging.
2001-11-05 Stefan Jahn <stefan@lkcc.org>
* struct.c (s_scm_struct_vtable_p): Corrected docstring.
2001-11-04 Stefan Jahn <stefan@lkcc.org>
* Makefile.am (libguile_la_LIBADD): Added $(THREAD_LIBS_LOCAL)
here (was at guile_LDADD) which describes the dependency
correctly and allows a clean build on Win32.
* __scm.h (SCM_API): Follow-up patch. Renamed __FOO__ macros
into FOO.
* __scm.h: USE_DLL_IMPORT indicates the usage of the DLL
import macros for external libraries (libcrypt, libqthreads,
libreadline and libregex).
* coop-defs.h: Include <winsock2.h> for `struct timeval'.
* posix.c (flock): Added support for flock() in M$-Windows.
* guile.c (SCM_IMPORT): Follow-up patch. Use SCM_IMPORT instead
of __SCM_IMPORT__.
* fports.c (getflags): Differentiate reading and writing pipes
descriptors.
* filesys.c (S_IS*): Redefine all of the S_IS*() macros for
M$-Windows.
* coop.c (coop_condition_variable_timed_wait_mutex): Use
conditionalized error code if `ETIMEDOUT' is not available.
(scm_thread_usleep): Remove bogus declaration of `struct timeval
timeout'.
* numbers.c (PTRDIFF_MIN): Moved this definition where it actually
belongs. That is because NO_PREPRO_MAGIC gets undefined after
each inclusion of `num2integral.i.c'.
(SIZE_MAX): Define NO_PREPRO_MAGIC if SIZE_MAX is undefined.
2001-11-03 Marius Vollmer <mvo@zagadka.ping.de>
* eval.c (scm_m_begin): Allow `(begin)`, with no subforms.
(SCM_CEVAL): Evaluate an empty `begin' to SCM_UNSPECIFIED.
2001-11-02 Mikael Djurfeldt <mdj@linnaeus>
* print.c (scm_iprin1): Mark print state as revealed when
dispatching to generic write or display.
* unif.c (scm_ra2contig): Fixed memory overwrite bug.
2001-11-02 Marius Vollmer <mvo@zagadka.ping.de>
Support for native Win32. Thanks to Stefan Jahn!
* Makefile.am: Add win32-uname.c, win32-uname.h, win32-dirent.c
and win32-dirent.h to extra source and header files. These
include the uname() and the POSIX dirent interface implementation
for M$-Windows. Put `-no-undefined' into LDFLAGS to support
linkers which do not allow unresolved symbols inside shared
libraries. Corrected `guile_filter_doc_snarfage$(EXEEXT)'
dependency.
* __scm.h: Defined SCM_API. This macro gets prepended to all
function and data definitions which should be exported or imported
in the resulting dynamic link library in the Win32 port.
* __scm.h, alist.h, arbiters.h, async.h, backtrace.h, boolean.h,
chars.h, continuations.h, coop-defs.h, coop-threads.h,
debug-malloc.h, debug.h, deprecation.h, dynl.h, dynwind.h,
environments.h, eq.h, error.h, eval.h, evalext.h, extensions.h,

tags.h, threads.h, throw.h, unif.h, values.h, variable.h, vectors.h,
vports.h, weaks.h:
Prefixed each each exported symbol with SCM_API.
* continuations.c: Added comment about the use of the extern
declarations of {get,set}context() functions used in the ia64 port.
* continuations.h, gc.c: `__libc_ia64_register_backing_store_base'
is meant to be a `unsigned long *'.
* filesys.c: Include `direct.h' if possible. Use local
`win32-dirent.h' for the native M$-Windows port. Define S_IS*()
macros for M$-Windows. Implementation of `fstat_Win32()' which is
able to differentiate between sockets and other file descriptors.
Use this function as wrapper in `scm_fstat()'. Fixed typo in
`scm_dirname()'.
* fports.c: Include `io.h' is possible. Put `*fp' into referring
statement block in `scm_fport_buffer_add()'.
Some corrections in `getflags()'.
* gdb_interface.h (GDB_INTERFACE): Also support __CYGWIN__.
* guile.c: Make sure to define __SCM_IMPORT__ for shared library
build on Win32. Disable preloaded symbols on Win2 platforms.
* ioext.c, ports.c: Include `io.h' is possible.
* mkstemp.c: Include `process.h' is possible.
* net_db.c: Disable extern declaration of `h_errno' for __CYGWIN__,
too.
Put `scm_return_entry()' into HAVE_GETSERVENT conditional.
* posix.c: Remove unnecessary dirent includes and defines. Include
local `win32-uname.h' for MinGW. Extern declaration of
`mkstemp()' for systems where it does not exists. Make
`getlogin()' available on M$-Windows.
* scmsigs.c: Made `usleep()' avalable on MinGW.
* stime.c: On M$-Windows `tzname[]' is known to be `_tzname[]'.
* win32-dirent.c: Include "win32-dirent.h", not "dirent.h".
* win32-uname.c: Include "win32-uname.h", not "uname.h".
2001-10-28 Mikael Djurfeldt <mdj@linnaeus>
* unif.c (scm_uniform_array_read_x, scm_uniform_array_write):
Don't apply scm_uniform_vector_length on arrays.
2001-10-14 Dirk Herrmann <D.Herrmann@tu-bs.de>
* eval.c (scm_lookupcar, scm_m_letstar, scm_m_do, iqq,
scm_m_define, scm_m_letrec1, scm_m_let, scm_m_expand_body,
scm_macroexp, unmemocopy, scm_eval_args, scm_deval_args,
SCM_CEVAL, scm_map, scm_init_eval): When building lists, prefer
scm_list_<n> over scm_cons[2]?.
(scm_unmemocar, scm_m_cond, scm_m_letstar, scm_m_letrec1,
scm_m_let, scm_m_atbind, unmemocopy, SCM_CEVAL, SCM_APPLY): Use
SCM_C[AD][AD]R instead of explicit form.
(scm_m_set_x, scm_m_cond, scm_m_letstar, scm_m_do): Reordered
comparison parameters.
(scm_m_case, scm_m_cond, scm_m_letstar, scm_m_do, SCM_CEVAL): Use
!SCM_NULLP instead of SCM_NIMP.
(scm_m_case): Don't copy the form. Renamed proc to clause and
minimized its scope. Renamed x to clauses. Removed side
effecting operation from macro call.
(scm_m_cond): Don't copy the form. Renamed arg1 to clause and
minimized its scope. Renamed x to clauses. Minimized the scope
of variable 'len'. Make sure the else clause is treated specially
even in case of '=>' occurences. Don't change the else to #t in
order to be able to distinguish this case in the evaluator. Leave
type checking of the recipient to the evaluator.
(scm_c_improper_memq): Made the comment somewhat clearer.
(scm_m_lambda): Renamed proc to formals. Removed unnecessary
test for SCM_IM_LET at the place of the formal parameters.
Simplified the formal parameter checking.
(scm_m_letstar): Added Comment. Renamed proc to bindings.
Renamed arg1 to binding and minimized its scope. Eliminated
unnecessary consing.
(scm_m_do): Renamed proc to bindings. Minimized the scope of
variable 'len'.
(build_binding_list): New static function.
(unmemocopy): Don't use SCM_TYP7 on pairs (it's unclean).
Further, split up the 'letrec' unmemoizing code to the
corresponding parts for 'do', 'let' and 'letrec', adding comments
to each form. Cleanup the handling of the do form (This removes
some *real* code :-).
(SCM_CEVAL): Removed side effecting operation from macro call.
Handle the 'else clause of the 'cond form specially - the symbol
'else is not replaced with #t any more.
2001-10-14 Gary Houston <ghouston@arglist.com>
* version.c (scm_version): use sprintf instead of snprintf,
for portability. thanks to Bill Schottstaedt.
2001-10-14 Mikael Djurfeldt <mdj@linnaeus>
* read.c (scm_lreadr): When user-defined hash procedure returns
SCM_UNSPECIFIED: Fall back to standard handling instead of raising
an exception. (This prevents parsing of uniform vectors from
interfering with parsing of numbers.)
2001-10-13 Marius Vollmer <mvo@zagadka.ping.de>
* numbers.c: Set NO_PREPRO_MAGIC when defining our version of
PTRDIFF_MIN. Thanks to Ken Raeburn.
2001-10-07 Marius Vollmer <mvo@zagadka.ping.de>
* Makefile.am (EXTRA_libguile_la_SOURCES): Added "mkstemp.c".
* eval.c (scm_m_atbind): First try to find the variable without
defining it locally; when it has not been found, define it
locally.
* modules.c (module_variable): Pass over variables that exist but
are unbound.
2001-10-06 Marius Vollmer <mvo@zagadka.ping.de>
* backtrace.c (display_backtrace_file_and_line): Only use
scm_basename when POSIX support is compiled in. Thanks to Chris
Cramer.
2001-10-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
* numbers.c (mem2uinteger): Return number read so far when coming
across a hexdigit after having read a # or if not reading a hex
value. This will enable the calling code to correctly handle
forms like 1e2. (The background is, that the exponent markers d,
e and f are also hexdigits.) Thanks to Mikael Djurfeldt for
providing this patch.
(mem2complex): Fix erroneous double-negation. Now, numbers like
1-i will be read correctly.
2001-10-12 Mikael Djurfeldt <mdj@linnaeus>
* debug.c (scm_mem_to_proc): Fixed typo in previous change.
* validate.h (SCM_VALIDATE_DOUBLE_DEF_COPY): New macro.
2001-10-12 Dirk Herrmann <D.Herrmann@tu-bs.de>
* print.c (scm_print_state_vtable, print_state_pool):
Initialize. These variables are now registered as gc roots.
(scm_current_pstate): Update documentation.
(scm_current_pstate, scm_make_print_state, scm_free_print_state,
scm_prin1, scm_init_print): print_state_pool is registered as a
gc root and thus does not need to be protected by a surrounding
pair any more.
(make_print_state): The car of print_state_pool no longer holds
the scm_print_state_vtable.
(scm_current_pstate, scm_make_print_state, print_circref,
scm_iprin1, scm_prin1, scm_iprlist): Prefer !SCM_<foo> over
SCM_N<foo>.
(scm_prin1): When building lists, prefer scm_list_<n> over
scm_cons[2]?.
(scm_iprlist): Removed a redundant SCM_IMP test.
(scm_simple_format): Use SCM_EQ_P to compare SCM values.
2001-10-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
* debug.c (scm_make_iloc): Prefer !SCM_<foo> over SCM_N<foo>.
(scm_memcons, scm_mem_to_proc): When building lists, prefer
scm_list_<n> over scm_cons[2]?.
(scm_mem_to_proc): Prefer SCM_CONSP over SCM_NIMP.
(scm_procedure_name): Use SCM_CADR instead of explicit form.
(debugobj_print): Coerce scm_intprint arg 1 to long, not int.
Thanks to Rob Browning for the patch (see log entry 2001-09-21) -
for some reason his patch didn't make it into the cvs.
2001-10-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
* numbers.c (mem2decimal_from_point): Cleaned up the parsing a
little bit - should even be somewhat more accurate now.
2001-10-08 Rob Browning <rlb@defaultvalue.org>
* gc.c: support ia64 register backing store.
(SCM_MARK_BACKING_STORE): new macro.
* continuations.h: support ia64 register backing store.
(struct scm_t_contregs): add ia64 register backing store.
* continuations.c: support ia64 register backing store.
(continuation_mark): mark ia64 register backing store.
(continuation_free): free ia64 register backing store.
(scm_make_continuation): capture ia64 register backing store.
(copy_stack_and_call): copy ia64 register backing store.
2001-10-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
* hashtab.c (scm_hash_fn_create_handle_x): The result of assoc_fn
is known to be #f if no entry is found. Thus, use !SCM_FALSEP
instead of SCM_NIMP to test for that case.
* strings.h (SCM_SET_STRING_LENGTH): Cast the length to
scm_t_bits instead of long.
2001-10-06 Marius Vollmer <mvo@zagadka.ping.de>
* tags.h (SCM_T_BITS_MAX, SCM_T_SIGNED_BITS_MAX,
SCM_T_SIGNED_BITS_MIN): New.
* numbers.h (SCM_MOST_POSITIVE_FIXNUM, SCM_MOST_NEGATIVE_FIXNUM):
Use them to make these macros computable by the preprocessor.
* num2integral.i.c (INTEGRAL2NUM): Let the preprocessor test
whether the integral type fits in a fixnum, not the compiler.
This removes a spurious compiler warning. Also, honor the
NO_PREPRO_MAGIC flag to suppress any preprocessor tests. This is
needed for `long long's.
* numbers.c: Define NO_PREPRO_MAGOC when including
num2integral.c.i for `long long' and `signed long long'.
2001-10-06 Mikael Djurfeldt <mdj@linnaeus>
These changes fixes a race condition in the Guile coop - pthread
compatibility code.
* coop.c (mother_awake_p): New variable.
(coop_create): Set mother_awake_p before creating or signalling
mother; wait until mother is going to sleep before returning.
(mother): Reset mother_awake_p before going to sleep.
2001-10-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
* options.c (protected_objects, scm_init_options): The content of
protected_objects is now protected from garbage collection using
scm_gc_register_root instead of scm_permanent_object.
(get_option_setting): New static function that computes an option
setting as it was formerly done in the function scm_options.
(get_documented_option_setting): New static function that
returns option documentation as it was formerly done in the
function scm_options. Note that documentation C strings are no
longer precomputed into SCM objects. Instead, they are converted
into SCM strings every time get_documented_option_setting is
called.
(change_option_setting): New static functions that modifies the
option setting as it was formerly done in the function
scm_options. The function is now exception safe, i. e. won't
cause a memory leak when interrupted. Further, only non-immediate
option values are added to the protection list.
(scm_options): This function now has only the purpose to dispatch
to to get_option_setting, get_documented_option_setting or
change_option_setting, depending on the arguments given to
scm_options.
(scm_init_opts): Don't convert documentation C strings into SCM
strings. Further, don't protect any object values: They _must_
be immediate values, otherwise there is no guarantee that they
have not been collected before anyway.
* options.[ch] (scm_t_option): Made type unsigned, name into a
constant char* and val into a scm_t_bits type.
(scm_options, scm_init_opts): The number of options is guaranteed
to be larger or equal to zero. Thus, the type is changed to
unsigned.
2001-10-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
* num2integral.i.c (NUM2INTEGRAL): Eliminated some warnings about
testing an unsigned value for being >= 0.
2001-10-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
* numbers.h: Removed old comment about using SCM_CAR to access
non-pair cells.
(SCM_MOST_POSITIVE_FIXNUM, SCM_MOST_NEGATIVE_FIXNUM): Make sure
the return value is signed. Thanks to Brian Crowder for the bug
report.
(SCM_SRS): Avoid unnecessary casting and don't unpack input
values. With this patch, SCM_SRS can be safely used for other
types than scm_t_signed_bits. However, it should still better be
an internal macro and thus be renamed to SCM_I_SRS.
(SCM_MAKINUM, SCM_INUM): Use proper casting.
2001-10-03 Gary Houston <ghouston@arglist.com>
* continuations.h, unif.h: in the descriptions of the bit patterns
of the heap cells, make bit 0 the least significant.
2001-09-25 Thien-Thi Nguyen <ttn@glug.org>
* chars.h (SCM_MAKE_CHAR): Use `scm_t_bits' instead of `intptr_t'.
Thanks to Golubev I. N.
2001-09-25 Gary Houston <ghouston@arglist.com>
* ports.c (scm_drain_input): extended the docstring. thanks to
Alex Schroeder and Thien-Thi Nguyen.
2001-09-23 Mikael Djurfeldt <mdj@linnaeus>
* validate.h (SCM_NUM2FLOAT, SCM_NUM2DOUBLE,
SCM_VALIDATE_FLOAT_COPY, SCM_VALIDATE_DOUBLE_COPY): New
macros. (The NUM names might soon change.)
* numbers.h: Added missing declarations.
2001-09-22 Mikael Djurfeldt <mdj@linnaeus>
* Makefile.am: Distribute num2float.i.c.
* num2float.i.c: New file, multiply included by numbers.c, used
to "templatize" the float <-> num conversion routines.
* numbers.c: New functions: scm_num2float, scm_float2num,
scm_num2double, scm_double2num.
2001-09-21 Rob Browning <rlb@defaultvalue.org>
* .cvsignore: really add version.h
* strings.h (SCM_SET_STRING_LENGTH): coerce "l" to a long.
Otherwise it fails on the alpha. However, we might rather choose
this size conditionally.
* numbers.c (scm_gcd): change "k" to a long from an int.
Otherwise it fails on the alpha. However, we might rather choose
this size conditionally.
* error.c (scm_wta): coerce char* to intptr_t before int
assignment.
* debug.c (debugobj_print): coerce scm_intprint arg 1 to long, not
int.
* chars.h (SCM_MAKE_CHAR): coerce value to intptr_t.
2001-09-20 Mikael Djurfeldt <mdj@linnaeus>
* numbers.c (scm_integer_expt): Accept inexact integer in second
argument. (Thanks to Bill Schottstaedt.)
2001-09-20 Rob Browning <rlb@defaultvalue.org>
* .cvsignore: add version.h
* versiondat.h.in: removed (obsolete).
* version.h.in: renamed from version.h.
(SCM_GUILE_MAJOR_VERSION): new public macro.
(SCM_GUILE_MINOR_VERSION): new public macro.
(SCM_GUILE_MICRO_VERSION): new public macro.
* version.h: renamed to version.h.in.
* version.c
(scm_major_version): support integer *_VERSION macros.
(scm_minor_version): support integer *_VERSION macros.
(scm_micro_version): support integer *_VERSION macros.
(scm_version): support integer *_VERSION macros.
2001-09-20 Mikael Djurfeldt <mdj@linnaeus>
* error.c, error.h: Made error keys globally accessible.
Applications might want to test for these or use them in a direct
call to scm_error.
* num2integral.i.c (NUM2INTEGRAL): Report an error when these
routines are passed an inexact. This change in behavior is
motivated by concordance with R5RS: It is more common that a
primitive doesn't want to accept an inexact for an exact.
2001-09-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
The following patch partially undoes my patch from 2001-06-30,
where I added the function scm_gc_mark_cell_conservatively. The
function is buggy, since it breaks guile during conservative
marking if a pointer on the stack points directly into the list of
free cells on the heap: With conservative cell marking this will
cause the whole free list to be scanned and marked - boom!
* gc.c (allocated_mark, MARK, heap_segment,
scm_gc_mark_cell_conservatively, scm_init_storage), gc.h
(scm_gc_mark_cell_conservatively): Remove function
scm_gc_mark_cell_conservatively and update the corresponding
comments and uses accordingly. Thanks to Christopher Cramer for
the patch. (Minor corrections by me.)
2001-09-15 Gary Houston <ghouston@arglist.com>
* root.h (scm_root_state): removed the continuation_stack and
continuation_stack_ptr members, which have no apparent purpose.
(scm_continuation_stack, scm_continuation_stack_ptr): #defines
removed.
* root.c (root_mark), init.c (restart_stack, start_stack), gc
(scm_igc): remove all references to contination_stack and
continuation_stack_ptr, avoiding allocation of a vector and
useless processing during gc.
2001-09-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
* guardians.c (tconc_t, t_tconc): Renamed tconc_t to t_tconc.
(TCONC_IN): Make sure that the cell word 0 is initialized last.
(guardians_t, t_guardians): Renamed guardians_t to t_guardians.
(GUARDIAN, GUARDIAN_DATA): Renamed GUARDIAN to GUARDIAN_DATA.
(guardian_apply, scm_get_one_zombie, scm_make_guardian,
mark_and_zombify): Prefer !SCM_<foo> over SCM_N<foo>.
2001-09-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
* guardians.c (mark_dependencies_in_tconc,
whine_about_self_centered_zombies, scm_init_guardians): Register
the static global variable `self_centered_zombies' via
scm_gc_register_root, to make some cdr-ing unnecessary.
2001-09-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
* backtrace.c (display_backtrace_file,
display_backtrace_file_and_line): Use SCM_EQ_P when comparing SCM
values, use SCM_FALSEP when comparing SCM values against #f.
Thanks to Rob Browning for the bug report.
2001-09-12 Martin Baulig <martin@home-of-linux.org>
* strings.[ch] (scm_str2string): New function.
2001-09-06 Marius Vollmer <mvo@zagadka.ping.de>
* gc.c (scm_done_free): Always subtract size from scm_mallocated
when computing nm, even if it's negative.
(scm_must_malloc): Abort on overflow of scm_mtrigger.
(scm_must_realloc): Likewise.
2001-09-01 Michael Livshin <mlivshin@bigfoot.com>
* numbers.c (scm_sys_check_number_conversions): new function,
defined if Guile is compiled in debugging mode. currently checks
`scm_num2ulong', should check much much more.
* num2integral.i.c (NUM2INTEGRAL): when converting a bignum to
unsigned, ensure that it's positive. thanks to Martin Baulig!
2001-08-31 Dirk Herrmann <D.Herrmann@tu-bs.de>
* __scm.h: Added new section about compile time selectable
features.
(long_long, ulong_long, scm_sizet, SCM_WNA, SCM_OUTOFRANGE,
SCM_NALLOC, SCM_HUP_SIGNAL, SCM_INT_SIGNAL, SCM_FPE_SIGNAL,
SCM_BUS_SIGNAL, SCM_SEGV_SIGNAL, SCM_ALRM_SIGNAL, SCM_GC_SIGNAL,

Extract side-effecting operations from macros.
(scm_init_eval): Don't initialize *top-level-lookup-closure*,
scm_top_level_lookup_closure_var and scm_system_transformer.
* gc.c (CELL_P): New local definition to replace SCM_CELLP.
(heap_segment): Use CELL_P instead of SCM_CELLP.
* init.c (start_stack): Don't initialize
scm_top_level_lookup_closure_var and scm_system_transformer.

* print.c (scm_ipruk): Don't access cell contents of non cells.
* strings.c (scm_string_set_x): All strings are writable.
* strings.h (SCM_STRINGP): Use SCM_TYP7 to determine the string
type. There is only one string type now.
(SCM_STRING_COERCE_0TERMINATION_X): Deprecated.
* tags.h: Remove comments about two different string types.
(SCM_CELLP, SCM_NCELLP): Deprecated.
* variable.c (make_variable): Remove code variant for vcells.
* variable.h (SCM_VARIABLE_REF, SCM_VARIABLE_SET,
SCM_VARIABLE_LOC): Remove code variant for vcells.

2001-07-08 Rob Browning <rlb@defaultvalue.org>
* .cvsignore: add stamp-h.in.
2001-07-04 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>

(scm_remove_hook_x, scm_reset_hook_x, scm_run_hook): Added return
value info to the docstrings.
2001-07-03 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
Some more compatibility patches for Windows.
* posix.c (getlogin): getlogin() implementation for Windows.

exist.
* cpp_sig_symbols.in: Added SIGBREAK.
2001-07-01 Marius Vollmer <mvo@zagadka.ping.de>
* strports.c (scm_read_0str, scm_eval_0str): Call
scm_c_read_string and scm_c_eval_string respectively, not
themselves. Thanks to Dale P. Smith!
2001-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
* unif.c (scm_array_set_x): The variable args does not
necessarily have to be a list. Further, got rid of a redundant
SCM_NIMP test.
2001-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
* list.c (SCM_I_CONS): Make sure the cell type is initialized
last.
* gc.c (s_scm_map_free_list, scm_igc, scm_gc_sweep,
init_heap_seg): Fixed signedness.
(init_heap_seg): Replaced strange for-loop with a while loop.
* weaks.h (WEAKSH, SCM_WEAKS_H): Rename <foo>H to SCM_<foo>_H.

The following patch adds conservative marking for the elements of
free or allocated cells.
* gc.c (allocated_mark, heap_segment): New static functions.
(which_seg): Deleted, since the functionality is now provided by
function heap_segment.
(map_free_list): Use heap_segment instead of which_seg.
(MARK): If cell debugging is disabled, mark free cells
conservatively.
(scm_mark_locations, scm_cellp): Extracted the search for the
heap segment of a SCM value into function heap_segment.
(scm_init_storage): Allocated cells must be marked
conservatively.
* gc.[ch] (scm_gc_mark_cell_conservatively): New function.
The following patch changes the representation of weak vectors to
double cells instead of using an extension of the vector's
allocated memory.
* gc.c (MARK): Use SCM_SET_WVECT_GC_CHAIN instead of assigning to
the result of SCM_WVECT_GC_CHAIN.
(scm_gc_sweep): Weak vectors don't have extra fields any more.
* weaks.c (allocate_weak_vector): New static function. It does
not patch any previously created vector object during the
construction of a weak vector, and thus doesn't need to switch
off interrupts during vector creation.
(scm_make_weak_vector, scm_make_weak_key_hash_table,
scm_make_weak_value_hash_table, scm_make_doubly_weak_hash_table):
Use allocate_weak_vector to provide the new weak vector object.
* weaks.h (SCM_WVECT_TYPE, SCM_SET_WVECT_TYPE,
SCM_SET_WVECT_GC_CHAIN): New macros. The weak vector subtype is
now stored in the double cell.
(SCM_IS_WHVEC, SCM_IS_WHVEC_V, SCM_IS_WHVEC_B, SCM_IS_WHVEC_ANY):
Use SCM_WVECT_TYPE.
(SCM_WVECT_GC_CHAIN): The weak objects are now chained together
using an entry of the double cell.
2001-06-30 Thien-Thi Nguyen <ttn@revel.glug.org>
* stamp-h.in: bye bye
2001-06-30 Marius Vollmer <mvo@zagadka.ping.de>

scm_eval_0str.
* load.c, load.h (scm_c_primitive_load,
scm_c_primitive_load_path): New.
* strports.c, strports.h (scm_c_read_string): Renamed from
scm_read_0str. Also, added "const" qualifier to argument.
(scm_c_eval_string): Renamed from scm_eval_0str.

scm_list_n): New functions.
(SCM_LIST0, SCM_LIST1, SCM_LIST2, SCM_LIST3, SCM_LIST4, SCM_LIST5,
SCM_LIST6, SCM_LIST7, SCM_LIST8, SCM_LIST9, scm_listify): Deprecated.
(lots of files): Use the new functions.
* goops.c (CALL_GF1, CALL_GF2, CALL_GF3, CALL_GF4): Use scm_call_N.
* strings.c: #include "libguile/deprecation.h".
2001-06-27 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
* read.c (scm_lreadr): When reading a hash token, check for a
user-defined hash procedure first, so that overriding the builtin
hash characters is possible (this was needed for implementing
SRFI-4's read synax `f32(...)').
* num2integral.i.c: Use scm_t_signed_bits instead of scm_t_bits,
because the latter is unsigned now and breaks comparisons like
(n < (scm_t_signed_bits)MIN_VALUE).
2001-06-26 Neil Jerram <neil@ossau.uklinux.net>
* eval.h, eval.c (scm_call_4): New function.
* eval.c (SCM_APPLY, SCM_CEVAL, ENTER_APPLY): Call trap handlers
directly rather than dispatching to them via scm_ithrow and a lazy
catch.
* eval.c (scm_evaluator_trap_table), eval.h (SCM_ENTER_FRAME_HDLR,
SCM_APPLY_FRAME_HDLR, SCM_EXIT_FRAME_HDLR): Add three new options
for trap handler procedures.

filter-doc-snarfage.c: remove.
2001-06-26 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>
* ports.c (scm_output_port_p): Use result of SCM_COERCE_OUTPORT.

Windows compilers easier. Compilation under GNU systems should
not be affected at all.

2001-05-24 Michael Livshin <mlivshin@bigfoot.com>
The purpose of this set of changes is to regularize Guile's usage
of ANSI C integral types, with the following ideas in mind:
- SCM does not nesessarily have to be long.
- long is not nesessarily enough to store pointers.
- long is not nesessarily the same size as int.
The changes are incomplete and possibly buggy. Please test on
something exotic.

Merged from mvo-vcell-cleanup-1-branch.
The concept of vcells has been removed from Guile. With it,
explicit obarrays and associated operations are gone. Use
hashtables instead of obarrays.
Throughout: use scm_sym2var instead of scm_sym2vcell and treat
result as variable instead of vcell. Glocs no longer point to a
vcell but to a variable. Use scm_c_define instead of
scm_sysintern and treat the result as a variable (which it is),
not a vcell.

mode, as suggested by Michael Livshin.
2001-03-31 Michael Livshin <mlivshin@bigfoot.com>
* backtrace.c (display_backtrace_body): since the `print_state'
variable is not used (instead its data field is used directly as
`pstate'), protect it from the hungry compiler optimizations.
thanks to Bill Schottstaedt for the report.
2001-03-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
* gc.[ch] (scm_tc16_allocated): New type tag for allocated cells.
It is only defined and used if guile is compiled with
SCM_DEBUG_CELL_ACCESSES set to true. It's purpose is, to never
let cells with a free_cell type tag be visible outside of the
garbage collector when in debug mode.
* gc.c (scm_debug_cell_accesses_p): Set to true as default.
(scm_assert_cell_valid): Use a local static variable to avoid
recursion.
(MARK): Only check for rogue cell pointers in debug mode. Use
scm_cellp for this purpose and place all checks for rogue pointers
into that function. Further, since due to conservative scanning
we may encounter free cells during marking, don't use the standard
cell type accessor macro to determine the cell type.
(scm_cellp): Check if the cell pointer actually points into a
card header.
(scm_init_gc): Initalize scm_tc16_allocated.
* gc.h (GCH): Renamed to SCM_GC_H.
(SCM_VALIDATE_CELL): Enclose the expression in brackets. This
might be unnecessary, but I feel better this way :-)
(SCM_GC_CELL_TYPE): New macro.
(SCM_SETAND_CDR, SCM_SETOR_CDR): Deprecated. These are not used
in guile, and it is unlikely that they will be applied to real
pairs anyway.
(SCM_SET_FREE_CELL_TYPE): Removed. It was not used.
(SCM_GC_SET_ALLOCATED): New macro. Only non-empty if guile is
compiled with SCM_DEBUG_CELL_ACCESSES set to true.
(SCM_NEWCELL, SCM_NEWCELL2): Use of SCM_GC_SET_ALLOCATED will
make sure that in debug mode no free cell will ever be visible
outside of the garbage collector.
2001-03-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
* async.c (scm_asyncs_pending): Don't use != to compare SCM
values.
* async.c (scm_system_async), variable.c (scm_make_variable,
scm_make_undefined_variable): Use scm_cons to create a pair.
* debug.c (scm_reverse_lookup): Perform proper type checking.
Remove suspicious use of SCM_SLOPPY_CONSP.
* eq.c (scm_equal_p), tags.h (SCM_ECONSP): Use SCM_CONSP instead
of SCM_SLOPPY_CONSP. A sane compiler should be able to perform
the corresponding optimization.
* eval.c (iqq): Use proper type check.
(scm_m_expand_body): Remove redundant type checks.
(promise_print): Don't access promise cells as pairs.
* eval.c (EVALCAR, iqq, scm_m_expand_body, scm_eval_args,
scm_deval_args SCM_CEVAL), guardians.c (scm_guard), hashtab.c
(scm_internal_hash_fold), print.c (scm_iprlist): Use !SCM_CELLP
for SCM_NCELLP, !SCM_CONSP for SCM_NCONSP, !SCM_IMP for SCM_NIMP,
!SCM_FALSEP for SCM_NFALSEP, !SCM_NULLP for SCM_NNULLP
* eval.c (scm_m_define, scm_macroexp, SCM_CEVAL), print.c
(scm_iprin1): Use new macro predicate and accessors.
* eval.h (scm_tc16_macro): Removed declaration. It is declared
in macros.h.
* eval.h (EVALH), macros.h (MACROSH), ports.h (PORTSH), procs.h
(PROCSH), tags.h (TAGSH), variable.h (VARIABLEH): Renamed to
SCM_EVAL_H, SCM_MACROS_H, SCM_PORTS_H, SCM_PROCS_H, SCM_TAGS_H and
SCM_VARIABLE_H. Even the macros that are used to inhibit
including a header file twice should be in the SCM_ namespace.
* fluids.c (scm_swap_fluids, scm_swap_fluids_reverse),
properties.c (scm_primitive_property_ref,
scm_primitive_property_del_x): Prefer stronger predicates like
SCM_NULLP or SCM_FALSEP over SCM_IMP.
* gc.c (MARK): Use proper macros to access procedure-with-setter
cell elements and closure cell elements.
(gc_sweep_freelist_finish, scm_gc_sweep, init_heap_seg): Don't
access free cells as pairs.
(scm_unprotect_object): scm_hashq_get_handle returns #f if
no hashtab entry is found.
* gc.c (scm_gc_sweep), ports.c (scm_close_port): Use new macro
SCM_CLR_PORT_OPEN_FLAG.
* guardians.c (TCONC_IN), print.c (scm_free_print_state): Don't
use SCM_SET_C[AD]R for uninitialized cells.
* hashtab.c (scm_hash_fn_get_handle): Use SCM_VALIDATE_VECTOR.
If the hashtable has no slots, return #f instead of '(). This
unifies the return value with most assoc-functions.
(scm_hash_fn_ref): Use proper type check.
(scm_hashq_get_handle, scm_hashv_get_handle, scm_hash_get_handle):
Removed references to non-existing functions from documentation.
* keywords.c (scm_keyword_dash_symbol): Use proper macros to
access keyword cell elements.
* macros.h (SCM_MACROP, SCM_MACRO_TYPE, SCM_MACRO_CODE): New
macros.
* ports.h (SCM_CLR_PORT_OPEN_FLAG): New macro.
* print.c (scm_iprlist): Added comment. Improved loop
conditions.
* procs.h (SCM_ENV, SCM_SETENV): Don't access closure cells as
pairs.
* smob.c (scm_markcdr): Don't access smob cells as pairs.
* tags.h (SCM_SLOPPY_CONSP, SCM_SLOPPY_NCONSP): Deprecated.
* throw.c (ACTIVATEJB, DEACTIVATEJB): Don't access jump buffer
cells as pairs.
* variable.c (variable_print, variable_equalp, scm_variable_ref,
scm_variable_set_x): Use proper macros to access variable cell
elements.
(scm_variable_bound_p): Don't use SCM_NEGATE_BOOL.
* variable.h (SCM_VARVCELL): Don't access variable cells as
pairs.
* vectors.c (scm_vector), weaks.c (scm_weak_vector): Simplified,
added FIXME comment, removed register specifier.
2001-03-29 Keisuke Nishida <kxn30@po.cwru.edu>

(scm_string_downcase, scm_string_capitalize_x),
(scm_string_capitalize): Rewrote and corrected docstrings.
(scm_string_ci_to_symbol): Made docstring more explicit.

errors with last change.
2001-03-25 Marius Vollmer <mvo@zagadka.ping.de>
* eval.c (scm_primitive_eval_x, scm_primitive_eval, scm_i_eval_x,
scm_i_eval): Moved the application of the system transformer from

unchanged. Thanks to Brett Viren for the hint.
2001-03-14 Martin Grabmueller <mgrabmue@cs.tu-berlin.de>

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

message.
* load.c (scm_search_path): Use SCM_ASSERT_TYPE to give details
about the expected type with the wrong-type-arg error message.
* smob.c (scm_make_smob): Abort on misuse of smob - it indicates
a C level bug that can't be fixed from scheme anyway.
2001-03-05 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
* eval.c (scm_m_letstar): Removed check for duplicate bindings.
Duplicate bindings are OK in a let* since a let* is semantically

* print.c (scm_print_options): Fixed texinfo in docstring.
* net_db.c (scm_getserv, scm_getproto, scm_getnet): Return #f if

return NULL instead of signalling an error.

* socket.c (scm_fill_sockaddr): don't allow buffer overflows when
taking an unexpectedly large filename for an AF_UNIX socket from
bind/connect/sendto (thanks to Martin Grabmueller).
* socket.c (scm_sock_fd_to_port, SCM_SOCK_FD_TO_PORT): removed the
former and adjusted the latter.
(scm_socket, scm_socketpair): cosmetic changes.
(scm_getsockopt, scm_setsockopt): declare optlen as int, not
size_t as socklen_t substitute. don't restrict args/return values
to INUM: allow full range of int or size_t.
(scm_fill_sockaddr): check arguments before allocating memory, to
avoid leakage. use malloc, not scm_must_malloc.
(scm_connect, scm_bind, scm_sendto): use int, not size_t as socklen_t
substitute. free the sockaddr structure before throwing an error.
(scm_init_add_buffer): procedure removed, together with its static
buffer scm_addr_buffer, which wouldn't be thread safe. instead,
define a macro MAX_ADDR_SIZE and declare the buffer where needed.
(scm_accept, scm_getpeername, scm_getsockname, scm_recvfrom,
scm_sendto): use a local buffer instead of scm_addr_buffer.
adjust for new SCM_SOCK_FD_TO_PORT. use int for address size,
not size_t.
(scm_recvfrom): set addr->sa_family to AF_UNSPEC before the recvfrom
call to detect whether recvfrom could be bothered to set the address.
(scm_init_socket): don't call scm_init_addr_buffer.

immediate, literal constant should be evaluated.
* eval.c (scm_s_duplicate_formals): New error message string.
(scm_c_improper_memq): New function.
(scm_m_lambda): Check for duplicate arguments.
(scm_ceval, scm_deval): When executing a body: only cons a new

in the non-toplevel loop.
(nontoplevel_cdrxnoap, nontoplevel_cdrxbegin, nontoplevel_begin):
New labels with the meaning of their non-"nontoplevel" partners,
but they are used when it is known that the body is not evaluated at
top-level.

reporting for empty combinations.

2001-02-21 Marius Vollmer <mvo@zagadka.ping.de>

2001-02-15 Keisuke Nishida <kxn30@po.cwru.edu>
* dump.c (scm_undump): Use SCM_CARLOC/SCM_CDRLOC to obtain the
address of car/cdr. (Thanks to Dirk Herrmann)

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

(scm_eval_x, scm_eval): Reimplement in terms of
scm_primitive_eval_x and scm_primitive_eval, respectively.
2001-02-09 Marius Vollmer <mvo@zagadka.ping.de>
* macros.c (scm_macro_name, scm_macro_transformer): Use

all uses.
* ports.c (scm_port_for_each): Make a snapshot of the port table
before iterating over it. The table might change while the user
code is running. With the snapshot, the user can depend on the
fact that each port that existed at the start of the iteration is
encountered exactly once. (ice-9 popen) depends on this.
2001-02-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
* strings.h (SCM_STRING_MAX_LENGTH): New macro.
* strings.c (scm_makstr, scm_take_str, scm_make_string): Added

2001-01-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
The following patch was sent by Martin Grabmueller. It makes sure
that in case of parameter errors the correct function name is
shown, and that parameter types are only checked once.
