Hi all, Is there any key that tells launchd to run something when user logs out? Thanks, Charles

Hi all, I have a launcd running on my system (as root) but I cannot find it. It launches a local afp share point using `mount_afp`. I have run `launchctl list` for all users, including the root user, and they all return blank (except the root user, see below). I have found the script that it uses for launching the share point but I cannot find the plist file that feeds the launchd. $ sudo ls /Library/Launch* && ls /Users/*/Library/Launch* && ls / System/Library/Launch* Password: /Library/LaunchAgents: /Library/LaunchDaemons: PACESupport.plist org.macports.OpenSSH.plist org.macports.rsyncd.plist /System/Library/LaunchDaemons: total 296 8 -rw-r--r-- 1 root wheel 1K Mar 20 2005 eppc.plist 8 -rw-r--r-- 1 root wheel 848B Aug 16 2007 distccd.plist 8 -rw-r--r-- 1 root wheel 828B Sep 29 14:36 ssh.plist 8 -rw-r--r-- 1 root wheel 800B Aug 31 2007 smbd.plist 8 -rwxr-xr-x 1 root wheel 794B Oct 6 17:00 com.apple.usbmuxd.plist* 8 -rw-r--r-- 1 root wheel 729B Mar 20 2005 printer.plist 8 -rw-r--r-- 1 root wheel 715B Sep 10 16:59 tftp.plist 8 -rw-r--r-- 1 root wheel 713B Oct 12 2007 com.apple.dnbvolunteer.plist 8 -rw-r--r-- 1 root wheel 697B Aug 31 2007 nmbd.plist 8 -rw-r--r-- 1 root wheel 692B Mar 24 2005 swat.plist 8 -rw-r--r-- 1 root wheel 682B Mar 20 2005 finger.plist 8 -rw-r--r-- 1 root wheel 678B Mar 24 2005 bootps.plist 8 -rw-r--r-- 1 root wheel 671B Mar 20 2005 ftp.plist 8 -rw-r--r-- 1 root wheel 628B Mar 26 2005 comsat.plist 8 -rw-r--r-- 1 root wheel 627B Oct 12 2007 com.apple.dnbobserver.plist 8 -rw-r--r-- 1 root wheel 627B Mar 20 2005 ntalk.plist 8 -rw-r--r-- 1 root wheel 625B Mar 20 2005 com.apple.periodic- weekly.plist 8 -rw-r--r-- 1 root wheel 623B Mar 20 2005 com.apple.periodic- monthly.plist 8 -rw-r--r-- 1 root wheel 615B Mar 20 2005 telnet.plist 8 -rw-r--r-- 1 root wheel 594B Mar 20 2005 com.apple.xgridcontrollerd.plist 8 -rw-r--r-- 1 root wheel 581B Mar 20 2005 login.plist 8 -rw-r--r-- 1 root wheel 579B Mar 20 2005 com.apple.periodic- daily.plist 8 -rw-r--r-- 1 root wheel 578B Mar 20 2005 exec.plist 8 -rw-r--r-- 1 root wheel 575B Mar 20 2005 shell.plist 8 -rw-r--r-- 1 root wheel 574B Mar 20 2005 com.apple.xgridagentd.plist 8 -rw-r--r-- 1 root wheel 566B Mar 20 2005 org.xinetd.xinetd.plist 8 -rw-r--r-- 1 root wheel 544B Oct 9 00:02 com.apple.ODSAgent.plist 8 -rw-r--r-- 1 root wheel 531B Mar 20 2005 org.postfix.master.plist 8 -rw-r--r-- 1 root wheel 524B Mar 26 2005 com.apple.portmap.plist 8 -rw-r--r-- 1 root wheel 516B Mar 20 2005 com.apple.syslogd.plist 8 -rw-r--r-- 1 root wheel 516B Mar 20 2005 com.vix.cron.plist 8 -rw-r--r-- 1 root wheel 495B Mar 20 2005 com.apple.KernelEventAgent.plist 8 -rw-r--r-- 1 root wheel 458B Aug 9 2007 com.apple.dashboard.advisory.fetch.plist 8 -rw-r--r-- 1 root wheel 447B Jan 8 2007 com.apple.mDNSResponder.plist 8 -rw-r--r-- 1 root wheel 446B Dec 14 2006 org.isc.named.plist 8 -rw-r--r-- 1 root wheel 445B Mar 20 2005 com.apple.atrun.plist 8 -rw-r--r-- 1 root wheel 437B Mar 20 2005 com.apple.nibindd.plist /System/Library/LaunchAgents: root# launchctl list com.google.keystone.daemon com.paceap.pacesupport com.apple.dashboard.advisory.fetch com.apple.dnbobserverd com.apple.KernelEventAgent com.apple.mDNSResponder com.apple.nibindd com.apple.periodic-daily com.apple.periodic-monthly com.apple.periodic-weekly com.apple.portmap com.apple.syslogd com.apple.usbmuxd com.vix.cron org.postfix.master org.xinetd.xinetd com.openssh.sshd Thanks, Charles

[Un]loading user agents on [Un]install
by Tim Schooley 30 Sep '08

30 Sep '08

Hi all, So I think this is probably quite a "sane" task to have to perform: - Upon installing a product, detect which users are logged in, and load the installed LaunchAgent script for each user. - Upon uninstalling the product, detect which users are logged in, and unload the LaunchAgent script for each user. These tasks would be performed preupgrade, postinstall, etc... I wrote the following script to perform this task: ---- for user in `/usr/bin/users` do echo "Loading agent for user $user..." /usr/bin/su -l $user -c "/bin/launchctl load -SAqua /Library/LaunchAgents/com.mycompany.myproduct.plist" EXIT_STATUS=$? if [ $EXIT_STATUS != 0 ] then echo "failed (non-fatal, status $EXIT_STATUS)." else echo "Done!" fi done ---- And similarly for unloading. The script works for the user that launched the installer. But if for example another user is logged in using Fast-User Switching, the following error is printed in the installer log when preupgrade attempts to unload the script: preupgrade[pid]: launchctl: Error unloading: com.mycompany.myproduct.plist Also, on post[upgrade/install], the following error is printed when attempting to load the script for other users: postupgrade[pid]: launch_msg(): socket is not connected I've searched around for answers to these issues, but had no luck. I was hoping someone here might be able to point me in the right direction? Many thanks for any help! Kind regards, Tim

launchd on freebsd
by Tsvetomir Dimitrov 28 Sep '08

28 Sep '08

Hello, There was a Google Summer of code project about porting launchd on FreeBSD. Is this project still active? Have you got any information about it or any other similar? I will be very happy to see launchd working on FreeBSD. Unfortunately I am still a beginner programmer, but I'll do my best to contribute in my free time. Thank you in advance! Best regards, Tsvetomir

Jeremy, launchd and the mechanisms it uses to receive notification that the network stack is up are asynchronous and callback-oriented, which means there is no guarantee of ordering. When launchd is notified an IP address has been assigned to an interface, the network stack is already "up", so there's no way to use NetworkState to be called before interfaces have had any addresses assigned to them. Even so, with all the launchd plists installed by Leopard, it's very likely that by the time launchd gets around to loading your process, the network is already up and sending out mDNS packets (on a Mac Pro that uses a static IP address with wired Ethernet, an interface coming online happens *very* early and *very* quickly during system startup) . On my latest-gen iMac, we're process ID 50 and the network is very much alive when we load. However you could set the RunAtLoad key, which will start your daemon as soon as the machine starts up. The network may already be up at that point so you should use SystemConfiguration/ SCNetworkCheckReachability/ifconfig/etc to check if the network is already up, and do your work appropriately. Otherwise it could exit, and hope the network doesn't come online while you are exiting (as I think there's a race condition in there that we've experienced). When the network goes offline, launchd should then ask you to exit, and then relaunch you as necessary. If you absolutely must be guaranteed that your daemon is called before any addresses are assigned to the machine, you cannot use launchd. Again, this is all from my experience—somebody else might prove me wrong. Ryan

NetworkState and order
by Jeremy Reichman 25 Sep '08

25 Sep '08

I'm wondering about the relationship between NetworkState and the networking stack. I haven't found a reference about the KeepAlive/NetworkState value and the relative order in launching jobs with it versus the loading of the network stack. When NetworkState is true, will that result in a job that starts before, during, or after the loading of the network stack? Is that order guaranteed? Thanks! -- Jeremy

Please excuse my last reply. I was a bit sleepy and missed the expat part. We can use libxml2 (http://xmlsoft.org/) It can parse a XML file to tree and some other functionality which we may or may not use. ezXML (http://ezxml.sourceforge.net/) is also a solution. It's smaller and simpler than libxml. I think libxml2 is better choice. I'm not sure however if ezXML won't perform better because its smaller. What do you think about this? Also do you know if the lib should have BSD license in order to be included in the FreeBSD's base? Cheers, Tsvetomir ----- Original Message ---- From: R.

Well, you don't necessarily have to go along with the direction I'm taking, but if you're on board, I could certainly use help and I think it would generally help the project if we started adding test coverage to launchd(8) by way of CUnit (http://cunit.sourceforge.net/) I'm a big fan of test-driven porting projects ;) One thing I actually loathe is working with expat, and we will likely need a plist XML file parser. I'm not entirely certain on the FreeBSD project's views on the APSL, but I think one way or another CF-lite is out of the picture (especially if we aim to push this into FreeBSD base). If you're up for it, I think that'd be a great place to start. If you'd like I can push my Git repository to a public web server where we can both collaborate on the development of test cases. What I've done thus far is really not much more than reacquainting myself with launchd(8)'s code, it feels like home, even after all these years :) Cheers, -R.
