we're sure to pick up any critical defines like _GNU_SOURCE early.
#include <limits.h> removed in favor of scmconfig.h inclusion when
appropriate. STDC_HEADERS based inclusion of stdlib.h,
sys/types.h, stddef.h, and sys/stdtypes.h removed in favor of
scmconfig.h inclusion when appropriate. Various Win32 related
definitions removed in favor of scmconfig.h inclusion when
appropriate.
(HAVE_UINTPTR_T): definition removed (see NEWS).
(SIZEOF_PTRDIFF_T): definition removed (see NEWS).
(HAVE_LONG_LONGS): definition removed (see NEWS).
(HAVE_LONG_LONG): definition removed (see NEWS).
(HAVE_PTRDIFF_T): definition removed (see NEWS).
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.
(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.
* configure.in: Temporarily replaced "copt" threads option with new
option "pthreads".
(USE_PTHREAD_THREADS): Define if pthreads configured.
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.
(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.
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.
* NEWS: Corrected remarks about SCM_API.
* configure.in: Defining USE_DLL_IMPORT definition to indicate
usage of DLL import macros in `libguile/__scm.h'.
(LIBOBJS): Removed `fileblocks.o' from the list of object files.
Somehow Jim Blandy's patch from 1997 did not survive.
2001-11-04 Stefan Jahn <stefan@lkcc.org>
* configure.in (EXTRA_DEFS): Follow-up patch. Using SCM_IMPORT
instead of __SCM_IMPORT__.
* readline.c (scm_readline_init_ports): Disable input/output
stream redirection for Win32. The readline package for Win32
does not support this. The guile-readline library works fine
for command line editing.
* readline.h (SCM_RL_API): Renamed __FOO__ macros into FOO.
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$-Windows.
* coop.c (coop_condition_variable_timed_wait_mutex): Use
conditionalized error code if `ETIMEDOUT' is not available.
(scm_thread_usleep): Remove bogus declaration of `struct timeval
timeout'.
* numbers.c (PTRDIFF_MIN): Moved this definition where it actually
belongs. That is because NO_PREPRO_MAGIC gets undefined after
each inclusion of `num2integral.i.c'.
(SIZE_MAX): Define NO_PREPRO_MAGIC if SIZE_MAX is undefined.
2001-11-04 Stefan Jahn <stefan@lkcc.org>
* md/Makefile.am (EXTRA_DIST): Added `i386.asm'.
* md/i386.asm: New file. Contains the Intel syntax version for
nasm/tasm/masm of the file `i386.s'.
* qt.h.in: Definition of QT_API, QT_IMPORT and QT_EXPORT.
Prefixed each symbols which is meant to go into a DLL.
* Makefile.am (libqthreads_la_LDFLAGS): Put `-no-undefined'
into LDFLAGS to support linkers which do not allow unresolved
symbols inside shared libraries.
(EXTRA_DIST): Add `libqthreads.def', which is an export file
definition for M$-Windows. It defines exported symbols. This is
necessary because the M$VC linker does not know how to export
assembler symbols into a DLL.
2001-11-04 Stefan Jahn <stefan@lkcc.org>
* srfi-13.h, srfi-14.h, srfi-4.h: Follow-up patch. Renamed
__FOO__ macros into FOO.

necessary/advisory.

or SCM_NCONSP, respectively.

objects.c. modules.c, goops.c, eval.c, debug.c: Changed all uses
of scm_tc3_cond_gloc and scm_tcs_cons_gloc. See above.

Removed.
* debug.h, debug.c (scm_make_gloc, scm_gloc_p): Removed.
* dynwind.c (scm_swap_bindings): Likewise.
(scm_dowinds): Updated to recognize lists of variables instead of
lists of glocs.

threads reorganization.
