frontend locking fixes locking for dpkg frontends. Implementation is in dpkg git and apt support is coming soon. |
[Impact]
apt acquires /var/lib/dpkg/lock but has to release it while running dpkg, offering a short window for other clients to acquire the lock. This implements /var/lib/dpkg/lock-frontend which will be acquired earlier and not released by apt for dpkg to run.
dpkg will try to acquire the frontend lock as well, unless told not to do so via an environment variable, which apt does; hence concurrent runs of dpkg without other locking can't happen.
[Test case]
Run strace apt install $something and check that lock-frontend is acquired at the beginning and not released until the end.
[Regression potential]
Frontend locking failures are in English, as there are no translations yet. More locks also mean more potential for locking to go wrong across programs, but since we don't have any waiting locks we at least won't deadlock. |
