From 0693f9ddad3d9af3d3424087557bbddce480ce3f Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Thu, 18 Dec 2008 17:31:57 -0800 Subject: Make sure lockfiles are unlocked when dying on SIGPIPE We cleaned up lockfiles upon receiving the usual suspects HUP, TERM, QUIT but a wicked user could kill us of asphyxiation by piping our output to a pipe that does not read. Protect ourselves by catching SIGPIPE and clean up the lockfiles as well in such a case.
