2008-07-25 Hans Boehm <> (Really mostly Ivan Maidanski)
Ivan's description of the patch follows. Note that a few pieces like the GC_malloc(0) patch, were not applied since an alternate had been previously applied. A few differed stylistically from the rest of the code (mostly casts to void * instead of target type), or were classified as too minor to bother. Note that all of Ivan's static declarations which did not correct outright naming bugs (as a few did), where replaced by STATIC, which is ignored by default. - minor bug fixing (for FreeBSD, for THREAD_LOCAL_ALLOC and for GC_malloc(0)); - addition of missing getter/setter functions for public variables (may be useful if compiled as Win32 DLL); - addition of missing GC_API for some exported functions; - addition of missing "static" declarator for internal functions and variables (where possible); - replacement of all remaining K&R-style definitions with ANSI C ones (__STDC__ macro is not used anymore); - addition of some Win32 macro definitions (that may be missing in the standard headers supplied with a compiler) for GWW_VDB mode; - elimination of most compiler warnings (except for "uninitialized data" warning); - several typos correction; - missing parenthesis addition in macros in some header files of "libatomic_ops" module. My highlights based on reading the patch: * allchblk.c: Remove GC_freehblk_ptr decl. Make free_list_index_of() static. * include/gc.h: Use __int64 on win64, define GC_oom_func, GC_finalizer_notifier_proc, GC_finalizer_notifier_proc, add getter and setters: GC_get_gc_no, GC_get_parallel, GC_set_oom_fn, GC_set_finalize_on_demand, GC_set_java_finalization, GC_set_dont_expand, GC_set_no_dls, GC_set_max_retries, GC_set_dont_precollect, GC_set_finalizer_notifier. Always define GC_win32_free_heap. gc_config_macros.h: Define _REENTRANT after processing GC_THREADS. * include/gc_cpp.h: Improve GC_PLACEMENT_DELETE test, handling of operator new[] for old Windows compilers. * include/gc_inline.h (GC_MALLOC_FAST_GRANS): Add parentheses around arguments. * dbg_mlc.c, malloc.c, misc.c: Add many GC_API specs. * mark.c (GC_mark_and_push_stack): Fix source argument for blacklist printing. * misc.c: Fix log file naming based on environment variable for Windows. Make GC_set_warn_proc and GC_set_free_space_divisor just return current value with 0 argument. Add DONT_USER_USER32_DLL. Add various getters and setters as in gc.h. * os_dep.c: Remove no longer used GC_disable/enable_signals implementations. (GC_get_stack_base): Add pthread_attr_destroy call. No longer set GC_old_bus_handler in DARWIN workaround. * pthread_support.c: GC_register_my_thread must also call GC_init_thread_local.
