Let me interrupt here to make sure I understand you. You've got a user who
has a locked file, has changes to that file, and is committing those
changes. The changes are getting committed to the repository correctly, but
you were expected to see the post-...unlock (?) hook run before the
post-commit one does. (You typed "post-lock", but I don't see anything in
the above description that describes something being locked that previously
There are some phrasings in your paragraph that make me think you might be
misunderstanding what Subversion does when committing locked files. You say
the master "automagicly unlocks the file" -- but that's not actually what
happens at all. The file remains locked by the user for the duration of the
commit. "Locked" doesn't mean "read-only". "Locked" means "reserved for
editing only by a particular user". So, in the core stages of a commit
scenario involving a locked file (where the committing user owns the lock,
of course), you should not expect to see any locking or unlocking happening,
and therefore no post-lock or post-unlock hooks.
But the Subversion client, by default, doesn't stop with the core commit
scenario. Unless you specify --no-unlock when committing (or unless your
runtime configuration area has "no-unlock" set), the client will follow up a
successful commit with an unlock operation. "Commit went well, my work is
done here, I don't need the lock any more." That kinda thing.
This is why the ordering of hooks for a commit with locks looks like so:
### transmit commit data
### upgrade commit transaction to a new revision
### commit comes back to the client successful
### unlock any locked files
