32-bit Command Line Tool and Launchd on Lion
by Dean Shavit 28 Feb '12

28 Feb '12

I've come across a bit of a stumper. I've got a LaunchDaemon that runs a script every hour. I've updated the script to include a command line tool from a third party, but the tool's architecture is i386 only. When I run the command in the terminal, as root, after using sudo -s it works fine. If I run the command in the terminal using /bin/sh [command] it fails with a "cannot execute binary file" error. If I run the command in the terminal using /bin/sh -c [command] it works. However, if Launchd runs the script the command fails, but all other commands in the script work perfectly. I suspect an evironment issue, but I can't figure it out. Help?

privileged process install
by Martin Grider 31 Jan '12

31 Jan '12

I'm attempting to install a root process via the methods outlined in the SMJobBless sample project. I got it working yesterday! Then today I added a bunch of functionality, tried to add it again, and suddenly I get the following (in the console): 1/31/12 3:17:08.594 PM launchdadd: FAILURE: Could not submit job to launchd. 1/31/12 3:17:08.594 PM launchdadd: FAILURE: Job com.myCom.myApp.helper could not be installed from /Users/grid/Library/Developer/Xcode/DerivedData/MyApp-gsejskndkewqemavjzmiltdpmzhs/Build/Products/Debug/MyApp.app/Contents/Library/LaunchServices/com.myCom.myApp.helper, reason 2. Does anyone know what is this "reason 2"!?!?!? Googling for an hour has not helped. Most of the things I did were adding linkages and dependencies in the project... only a minimal amount of code was written. I've tried unsuccessfully to get back to the state I was in yesterday. Any clues would be really appreciated. Thanks in advance, -martin

WatchPaths jobs just quit working sometimes. If program exits nonzero status?
by Jerry Krinock 31 Jan '12

31 Jan '12

I support and test an app that uses the WatchPaths trigger in a launchd job. About once a month, I find that a WatchPaths trigger will *just stop working*. Running 'launchctl list', I see that my job is still loaded. The throttle interval is 60 seconds, and my program has exited. Yet I can wait many minutes, touch the WatchPath repeatedly, but launchd just ignores it. If I simply unload the job, then reload the job, it always starts working again. Has anyone ever seen this behavior besides me? The last couple times it's occurred, I've noted that the previous time my program was launched, it had exited with nonzero status. This is indicated in the output of 'launchd list'. Further tests indicate that exiting with nonzero status is not sufficient to cause the WatchPaths trigger to stop working. But I'm thinking that it may be a necessary condition, and so I'm going to modify my program to always exit with 0 status. I report errors by other means anyhow. Thanks for any comments on this. Is there any way to get more debugging info out of launchd? Jerry Krinock

Therefore this is what launchctl does when called from the root user session which is not what you want since you actually want to talk to the root user context (and control the root user agents). This is why you need the "-u root" option to tell launchctl that you want to talk to the root user context instead of switching to the system context. > >>> Thomas Clement <tclementdev(a)gmail.com> 12/22/2011 3:04 PM >>> > The "-u" flag only works for the root user. > Maybe you can have a condition in your shell script and use the "-u root" option only when appropriate. > > Thomas > > On Dec 22, 2011, at 10:29 AM, Nandini Vijayashankar wrote: > >> Hi, >> >> Thanks a lot... >> Its working from root user login. >> If I use the same command from non-root user login, iam getting error. >> I used: >> launchctl -u <username> unload /System/Library/LaunchAgents/<plistfile> >> Unknown user:<username> >> >> I want to use a generic command from my shell script to unload the plist file which is applicable for both root and non-root user login. >> Is it possible? >> >> Thanks >> >> >>> Thomas Clement <tclementdev(a)gmail.com> 12/22/2011 2:40 PM >>> >> Hi, >> >> You should try: >> launchctl -u root unload /System/Library/LaunchAgents/<plistfile> >> >> Thomas >> >> On Dec 22, 2011, at 6:00 AM, Nandini Vijayashankar wrote: >> >>> Hi, >>> >>> I want to know how does launchd start the user defined launchagents service when a "root" user logs in to the system. >>> >>> Iam using Mac 10.6 >>> >>> I have a launchdaemon and launchagent present in /System/Library/LaunchDaemons and /System/Library/LaunchAgents. >>> >>> When I login with a non-root user, my launchagent service is started as that logged in user. >>> I can unload this service using "launchctl unload /System/Library/LaunchAgents/<plistfile>" >>> >>> If I login as root user,my launchagent service is started and working fine.But its not started as logged in user ie., root. >>> If I try to unload through "launchctl unload /System/Library/LaunchAgents/<plistfile>" I get error: >>> launchctl : Error unloading <id> >>> >>> This is because the service is not launched as root user. >>> >>> Above scenarios are working fine in Mac 10.5 as root and non-root user. >>> >>> When i see my launchagent service in Activity monitor, the parent process is the per-user launchd instance. >>> The parent process of this launchd is system launchd with pid 1. >>> >>> I have tried to list the service using various commands: >>> launchctl list >>> launchctl bslist >>> sudo launchctl list >>> >>> All these are not showing my launchagent service.Is there any special way, launchd launches launchagents service when a root user logs in Mac 10.6? >>> >>> How can i unload my launchagent service when the root user logs in? >>> >>> >>> >>> >>> _______________________________________________ >>> launchd-dev mailing list >>> launchd-dev(a)lists.macosforge.org >>> http://lists.macosforge.org/mailman/listinfo.cgi/launchd-dev >> >

The "-u" flag only works for the root user. Maybe you can have a condition in your shell script and use the "-u root" option only when appropriate.

Problem with launchd starting user defined launchagent service in root user login
by Nandini Vijayashankar 22 Dec '11

22 Dec '11

Hi, I want to know how does launchd start the user defined launchagents service when a "root" user logs in to the system. Iam using Mac 10.6 I have a launchdaemon and launchagent present in /System/Library/LaunchDaemons and /System/Library/LaunchAgents. When I login with a non-root user, my launchagent service is started as that logged in user. I can unload this service using "launchctl unload /System/Library/LaunchAgents/<plistfile>" If I login as root user,my launchagent service is started and working fine.But its not started as logged in user ie., root. If I try to unload through "launchctl unload /System/Library/LaunchAgents/<plistfile>" I get error: launchctl : Error unloading <id> This is because the service is not launched as root user. Above scenarios are working fine in Mac 10.5 as root and non-root user. When i see my launchagent service in Activity monitor, the parent process is the per-user launchd instance. The parent process of this launchd is system launchd with pid 1. I have tried to list the service using various commands: launchctl list launchctl bslist sudo launchctl list All these are not showing my launchagent service.Is there any special way, launchd launches launchagents service when a root user logs in Mac 10.6? How can i unload my launchagent service when the root user logs in?

SMJobBless and plugins
by Jérome Laurens 25 Nov '11

25 Nov '11

Hi, I need to run an authorized tool from a preference pane. Actually, SMJobBless sample code explains how to install and run a tool from an application but it seems to me that it can't work for a plugin. A workaround I can see is to ship the preference pane with an installer app that contains the daemon. But I have no real idea of the security concerns of such a design. Any hint ? Thanks in advance JL

The MachService key
by Jerry Krinock 23 Nov '11

23 Nov '11

In trying to understand how a process works, I found a launchd plist with a MachService key. From launchd.plist(5), I learn that that this is to "specify Mach services to be registered with the Mach bootstrap sub-system". I know a little about the Mach bootstrap sub-system, but I can't find much information about Mach services. Does anyone know a book or other resource where I could learn about Mach services? Thanks, Jerry Krinock
