[stable19] Unlock when promoting to exclusive lock fails - #24076
Merged
Conversation
In certain cases changeLock to EXCLUSIVE fails and throws LockedException. This leaves the file locked as SHARED in file_put_contents, which prevents retrying (because on second call file_put_contents takes another SHARED lock on the same file, and changeLock doesn't allow more than a single SHARED lock to promote to EXCLUSIVE). To avoid this case, we catch the LockedException and unlock before re-throwing. Signed-off-by: Ashod Nakashian <ashod.nakashian@collabora.co.uk>
