Verify that pending changesets are seen by pretxn* hooks but not by other
|
|
processes that access the destination repo while the hooks are running.
|
|
|
|
The hooks (python and external) both reject changesets after some think time,
|
|
during which another process runs pull. Each hook creates a file ('notify') to
|
|
indicate to the controlling process that it is running; the process removes the
|
|
file to indicate the hook can terminate.
