* * gc.h, gc.c (SCM_FREECELL_P): Removed for good.Marius Vollmer2005-03-101-4/+9
| | | | | | | | | | | | | | | | | | | | | | (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.

| | | | | | | | | | | scm_gc_mallocated, for now. (scm_init_storage): Initialize it. * gc-malloc.c (descrease_mtrigger, increase_mtrigger): Use it. * gc-mark.c (scm_gc_mark_dependencies): Call scm_i_string_mark, scm_i_stringbuf_mark and scm_i_symbol_mark, as appropriate. * gc-card.c (scm_i_sweep_card): Call scm_i_string_free, scm_i_stringbuf_free and scm_i_symbol_free, as appropriate.

* (decrease_mtrigger): new functionHan-Wen Nienhuys2003-07-061-13/+35
| | | | | | | | | | (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.
* (scm_gc_register_collectable_memory): avoidHan-Wen Nienhuys2003-05-141-2/+11
| | | | | | wrap-around for scm_mtrigger (scm_gc_register_collectable_memory): abort on overflowing scm_mallocated().

* * gc.c, gc.h (scm_i_sweep_mutex): New mutex.Mikael Djurfeldt2002-12-211-11/+15
| | | | | | | | | | | | | | * 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.

| | | | | | | | | | | | * 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.
* * gc-malloc.c (malloc_mutex): New mutex.Mikael Djurfeldt2002-12-101-0/+12

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (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.
