# Test extension that adds delays before or after acquiring a lock.
|
|
#
|
|
# This extension can be used to test race conditions between lock acquisition.
|
|
#
|
|
# The delays are controlled by environment variables. The ``DELAY``
|
|
# environment variable sets a flat delay in seconds. The ``FILE``
|
|
# environment variable sets a filename, and the lock is delays until
|
|
# that file is removed.
