Re: [Bug 978356] Re: squid3 gets killed at startup with dnsmasq and no networkmanager
Excerpts from Daniel Hahler's message of Tue May 15 08:53:06 UTC 2012: > For what it's worth, this does not happen with the squid-deb-proxy > package (which uses squid with an optimized config) - at least after > several boot processes. > > The init/start script is different, for example, it uses > "start on (local-filesystems and net-device-up IFACE!=lo)" This is basically wrong. A system may have more than one interface and there is no guarantee that one of them is "the right one". That said, this makes perfect sense, because with NM, this will delay the start until *after* the first interface comes up, whereas with runlevel 2, that event will actually come before the first interface is up, so that starts the window where squid is starting up, polling for DNS entries and failing, and then it gets HUP just as the interface comes up. My patch to ignore HUP early on should solve this issue, but I haven't pushed it back upstream yet. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to squid3 in Ubuntu. https://bugs.launchpad.net/bugs/978356 Title: squid3 gets killed at startup with dnsmasq and no networkmanager To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dnsmasq/+bug/978356/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

[Bug 978356] Re: squid3 gets killed at startup with dnsmasq and no networkmanager
Have the same behaviour on a x86_64 server freshly-upgraded from Oneiric to Precise. On system reboot, squid3 does not start properly - gets killed by HUP signal as recorded in syslog. Logging into the system by ssh and manual starting service squid3 helps to resolve the problem. But having squid3 starting normally on bootup would be very beneficial. I strongly suspect this misbehaviour happens due to incomplete integration of upstart, ifupdown and resolvconf packages functionality. I use system without NetworkManager (it's a server after all), my interfaces are controlled by ifupdown and by ppp scripts. Probably upstart starts ifupdown too early, again as it usually happens when you have resolvsconf in universe instead of main. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to squid3 in Ubuntu. https://bugs.launchpad.net/bugs/978356 Title: squid3 gets killed at startup with dnsmasq and no networkmanager To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dnsmasq/+bug/978356/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Do you think adding a workaround like "sleep 5" above the "reload" into the resolvconf script makes sense and is good enough for a workaround in Ubuntu Precise?

[Bug 978356] Re: squid3 gets killed at startup with dnsmasq and no networkmanager
squid3 includes a resolvconf script to run whenever DNS servers change: #!/bin/sh PATH="/usr/sbin:/usr/bin:/sbin:/bin" # Make squid aware of changes to resolv.conf if status squid3 | grep "start/running" > /dev/null; then reload squid3 fi reconfigure also ends a HUP: if (!strncmp(optarg, "reconfigure", strlen(optarg))) /** \li On reconfigure send SIGHUP. */ opt_send_signal = SIGHUP; And yes, thats what I mean, there's a lag between when squid might receive the HUP, and when it will handle it properly. I'd rather ignore that HUP than die, since most of what it is doing at that exact time is reading its configuration and then attempting DNS lookups.

[Bug 978356] Re: squid3 gets killed at startup with dnsmasq and no networkmanager
So I think what is happening is that the network interface is coming up before squid has installed a handler for SIGHUP. *tons* of stuff happens between squid starting, and squid installing its signal handlers. I haven't gone through all of the code but I'm betting at least one or two stall on not having a network yet. It would seem that squid should probably ignore SIGHUP almost immediately on startup to avoid this issue.

[Bug 978356] Re: squid3 gets killed at startup with dnsmasq and no networkmanager
I experience the same issue, but have NetworkManager installed - although it does not manage the eth0 interface (I am using guessnet for that). ** Summary changed: - squid3 crash at startup with dnsmasq and no networkmanager + squid3 gets killed at startup with dnsmasq and no networkmanager -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to squid3 in Ubuntu. https://bugs.launchpad.net/bugs/978356 Title: squid3 gets killed at startup with dnsmasq and no networkmanager To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/squid3/+bug/978356/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
