Subject: [PATCH] lockfile: reset the correct signal
Date: Mon, 26 May 2008 21:35:13 +0200	[thread overview]
Message-ID: <20080526193513.GA9978@localhost> (raw)
In-Reply-To: <alpine.DEB.1.00.0805261031480.30431@racer>

In the function remove_lock_file_on_signal(), the signal handler
for SIGINT was reset, ignoring the parameter signo.

This did not pose a problem yet, as remove_lock_file_on_signal()
was only registered as a SIGINT handler.

Thank you for fixing that.

I also realized that using signals like that can cause races. Shouldn't we
use sigaction() instead of signal()?
