commit 62473af6a02e6d36d8ba6a3bc4e205e22eb0ea86
Author: remm <[email protected]>
AuthorDate: Thu Oct 24 09:34:05 2024 +0200
Minor fixes
Stop using the Lock-Token header for isLocked (clearly not used for
that).
More accurate matching of the token (append : and >).
Cleanup the unlock for shared locks, although no real change (unless
there's a token with no shared lock anymore, which should not really
happen).
Drop old unlockResource method (the shared lock unlock probably had some
issue since it seemed to only remove the first one), and replace it with
a much simpler deletedResource.
