* Fix garbage marking in gc_collect_roots()Nikita Popov2018-03-071-5/+4
| | | | | | | | 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.

These macros are going to be used to eliminate race-condintions during reference-counting on data shared between threads.

| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
