launchd WatchPaths not triggered by CGI file change

[hsthompson]

I’m posting somewhat off-topic here, since I’m using Mac OS X client instead of server; but the reason is that I found extensive information on this site about the subject that brings me here today: launchd. Please feel free to move or delete this thread if it violates the rules.

I have a Launch Agent watching a directory (WatchPaths). When a file is added, removed, or altered by user interaction, the Agent is triggered. However, I need it to be triggered by updates being made by a CGI script — which it is not currently doing.

Mac OS X 10.4.10 Client
Intel Mac Mini 2.0

What does the script actually do?

It is an rsync command:
[code]#! /bin/sh
rsync -avz –delete-after ~/Desktop/testfolder [email protected]:./public_html/[/code]

And launchd is watching which path in that script?

[hsthompson]

It’s watching the local directory, ~/Desktop/testfolder.

10.4 had a bug that required the filesystem object being “watched” exist in a permanent way. If this is a directory you’re creating and deleting dynamically, it won’t work on 10.4. If it is persistent then I’d probably have to see the plist and suggest manually touching the directory after rsync completes to see if that helps anything.

[hsthompson]

OK, here’s the plist.

[code]

Label
com.myname.mylaunchd
LowPriorityIO
OnDemand
ProgramArguments

/Users/myuser/myscript.sh

WatchPaths

/Users/myuser/Sites/mysite

[/code]

[khiltd]

Well, you said it was watching ~/Desktop/testfolder, but that plist clearly indicates it’s watching ~/Sites/mysite.

[hsthompson]

Sorry — I’ve been jumping between tests of the implementation. The basic XML is the same between them, but the directories are different.

[khiltd]

If you’re positive you’re loading the right job then touching the directory is all I can think of off the top of my head.

I’m not entirely sure if it will actually swallow a directory now that I think about it–may be restricted to actual files. Can’t remember if it’s supposed to work or not in 10.4.
