| Description |
|
metadata_lock_info part is already implemented, just needs to be checked out: However APC subsystem processes requests only when query plan is available. It needs to be adjusted so that it fills data even if a plugin is idle or waiting for MDL lock. There is also a minor bug in that revision: it iterates requestor thread ticket list, while it should iterate target thread ticket list instead. |
