[Bug 978356] Re: squid3 gets killed at startup with dnsmasq and no networkmanager

[Clint Byrum]

** Description changed:

+ [ Test case ]
+ This is difficult to test as it is a race condition, however there are multiple users affected.
+ 
+ 1. install squid3 on a system which has a system level network connection
+ 2. reboot
+ 3. on bootup, check to see if squid3 is running (service squid3 status). If it is not running, check /var/log/syslog and the system console for a message about squid3 being killed by SIGHUP.
+ 4. Install updated package
+ 5. repeat step 3, If it is running, this *might* be fixed (but as it is a race, there are no guarantees).
+ 
+ [ Regression Potential ]
+ This update only touches the upstart job, so it will only affect that. Upstart's respawn code is fairly conservative, and the upstart job is fairly straight forward. Definitely a few reboots with updates installed should prove this update regression-free.
+ 
+ -------------
+ 
  I've 12.04 - 32bit pae, and removed networkmanager (aptitude purge) since I'm using it as a LTSP server.
  squid3 3.1.19-1ubuntu1,  dnsmasq 2.59-4
  Linux gnusc 3.2.0-22-generic-pae #35-Ubuntu SMP Tue Apr 3 20:37:36 UTC 2012 i686 athlon i386 GNU/Linux
  
  I install dnsmasq and squid3. I've noticed that squid3 was never working at boot.
  dmesg shows a:
  root at gs1204:~# dmesg | grep squid
  [   20.227964] init: squid3 main process (1310) killed by HUP signal
  
  If I remove dnsmasq (aptitude purge) squid has no problem. Don't know if is related to the recent mechanism so resolv.conf is automatically updated by dnsmasq or not.
  At the moment I've setup the workaround of run squid3 from rc.local, but of course is not a clean solution
