3b5b64ce75 Fix garbage marking in gc_collect_roots() 
gc_collect_white() will mark white nodes as black and add them as
garbage, but only if it's not buffered yet. The already buffered
roots are instead marked as garbage in gc_collect_roots() directly.
However, if gc_collect_white() marked a (buffered) root as black
through recursion, it would not subsequently be marked as garbage.

ab139b6bfd Reverted e6d6fcedf7 and overdesign introduced in ae64dd6d56. 
Now we have just indexex, pointers and linked list od unused buffers.

a0563aa7bc Fix incorrect GC_NUM2ADDR usage 
Both first_unused and GC_MAX_UNCOMPRESSED are addresses, so we
should compare them directly.

49ea143bbd Encapsulate reference-counting primitives. 
Prohibit direct update of GC_REFCOUNT(), GC_SET_REFCOUNT(), GC_ADDREF() and GC_DELREF() shoukf be instead.
Added mactros to validate reference-counting (disabled for now).
These macros are going to be used to eliminate race-condintions during reference-counting on data shared between threads.

a082824725 Replace redundand checks with ZEND_ASSERT. We shouldn't get IS_OBJECTs without object_storage. 2017-02-03 18:31:25 +03:00

fd4025069d
Enable HT RC assertions with escape-hatch 
HT functions that modify the array now assert that rc=1. As we don't
respect this COW constraint everywhere, either for a good reason or
because fixing it would take more work, we provide an escape hatch
in the form of HT_ALLOW_COW_VIOLATION(ht). If this macro is called
assertions on this ht are disabled. The macro is a no-op in release
mode.

5513f00a97 Fixed a potential segfault in zend_objects_store_free_object_storage() 
Under the special circumstance where a garbage collected objects bucket slot was not reused until the end of the script, we get access into freed memory...
No test added as it usually is valgrind-only, and only sometimes when the memory happens to have changed (i.e. (GC_FLAGS(obj) & IS_OBJ_FREE_CALLED) == 0), it actually *may* segfault
