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.
* configure.in: Checking for __int64 as possible candidate for
the SCM_I_GSC_T_INT64 define.
2003-06-14 Stefan Jahn <stefan@lkcc.org>
* threads.h: Redefined scm_getspecific() and scm_setspecific()
to be functions instead of macros.
* threads.c: Conditionalized inclusion of <sys/time.h> and
<unistd.h>.
(scm_getspecific, scm_setspecific): Made these two function
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.
(void *) in order to avoid an aliasing warning; thanks to Bruce
Korb.)

SCM_STACK_PTR.

symbols to expect 0 or 1 values rather than 1 or undefined.
i.e. change #ifdef to #if, etc.
* null-threads.c: fix various preprocessor usages of new public
symbols to expect 0 or 1 values rather than 1 or undefined.
i.e. change #ifdef to #if, etc.
* coop-threads.c: fix various preprocessor usages of new public
symbols to expect 0 or 1 values rather than 1 or undefined.
i.e. change #ifdef to #if, etc.
* coop-pthreads.c: fix various preprocessor usages of new public
symbols to expect 0 or 1 values rather than 1 or undefined.
i.e. change #ifdef to #if, etc.
any critical defines like _GNU_SOURCE early. Replace usage of
struct timespect with scm_t_timespec. Replace usage of
STACK_GROWS_UP with SCM_STACK_GROWS_UP. Replace usage of
USE_PTHREAD_THREADS with SCM_USE_PTHREAD_THREADS.
* 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.
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.
(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.
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.
* 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.
(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.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.
"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".

New.

requested.

(scm_try_mutex, scm_broadcast_condition_variable): Newly
registered procedures.
(scm_wait_condition_variable, scm_timed_wait_condition_variable):
Use the latter as the procedure for "wait-condition-variable",
thus offering a optional timeout parameter to Scheme.
(scm_wait_condition_variable): Implement in terms of
scm_timed_wait_condition_variable.
(scm_mutex_init, scm_mutex_lock, scm_mutex_trylock,
scm_mutex_unlock, scm_mutex_destroy, scm_cond_init,
scm_cond_wait, scm_cond_timedwait, scm_cond_signal,
scm_cond_broadcast, scm_cond_destroy): Implement in terms of
scm_make_mutex, etc, and deprecate.
(scm_init_threads): Do not create smobs, leave this to
scm_threads_init. Do not include "threads.x" file.
(scm_init_thread_procs): New, include "threads.x" here.
* null-threads.h (scm_null_mutex, scm_null_mutex_init,
scm_null_mutex_lock, scm_null_mutex_unlock,
scm_null_mutex_destroy, scm_null_condvar, scm_null_condvar_init,

handled by threads.{h,c}.

sizes.
(block): Removed, now unused.

scm_null_mutex_destroy, scm_null_condvar_init,
scm_null_condvar_wait, scm_null_condvar_signal,
scm_null_condvar_destroy): Removed and updated users to do their
task directly.

(scm_wait_condition_variable): Removed.
* coop-threads.c (scm_threads_init): Create smobs here, using the
appropriate sizes.
(scm_c_thread_exited_p, scm_try_mutex,
scm_timed_wait_condition_variable,
scm_broadcast_condition_variable): New.
(scm_wait_condition_variable): Removed.
* threads.c: Include null-threads.c when !USE_COOP_THREADS.
(scm_init_threads): Use generic type names scm_t_mutex and
scm_t_coop instead of coop_m and coop_t.
and we don't want that.
(INCLUDES): Removed all -I options except for the root source
directory and the root build directory.
* *.*: Change includes so that they always use the "prefixes"
libguile/, qt/, guile-readline/, or libltdl/.
