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. |
