# Test for race condition fixed by https://github.com/systemd/systemd/pull/30768
|
|
# Here's the schedule of events that we to happen during this test:
|
|
# (This test) (The service)
|
|
# .path unit monitors /tmp/copyme for changes
|
|
# Take lock on /tmp/noexeit ↓
|
|
# Write to /tmp/copyme ↓
|
|
# Wait for deactivating Started
|
|
# ↓ Copies /tmp/copyme to /tmp/copied
|
|
# ↓ Tells manager it's shutting down
|
|
# Ensure service did the copy Tries to lock /tmp/noexit and blocks
|
|
# Write to /tmp/copyme ↓
|
|
#
|
|
# Now at this point the test can diverge. If we regress, this second write is
|
|
# missed and we'll see:
|
|
# ... (second write) ... (blocked)
|
|
# Drop lock on /tmp/noexit ↓
|
|
# Wait for service to do copy Unblocks and exits
|
|
# ↓ (dead)
|
|
# ↓
|
|
# (timeout)
|
|
# Test fails
|
|
#
|
|
# Otherwise, we'll see:
|
|
# ... (second write) ... (blocked)
|
|
# Drop lock on /tmp/noexit ↓ and .path unit queues a new start job
|
|
# Wait for service to do copy Unblocks and exits
|
|
# ↓ Starts again b/c of queued job
|
|
# ↓ Copies again
|
|
# Test Passes
