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.
