site_archiver(a)lists.apple.com Delivered-To: darwin-dev(a)lists.apple.com Hi Peter, Thanks for your response. I think perhaps my question wasn't clear.

Darwin-dev mailing list (Darwin-dev(a)lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/darwin-dev/site_archiver%40lists.app… I'm trying to work around the documented limitation in launchd (on Tiger) that prevents it from being used to launch a process at user login. The limitation, as I understand it, is that there's no way to prevent launchd from launching the process even if the user logs in via a non-GUI method like ssh. So, I guess what I'm asking is if, *once I have been launched as a Login Item*, I can leverage launchd to simply re-launch me properly if I should crash. Or, does a subsequent launch-on-crash suffer the same basic problem that prevents launching me at login in the first place? If using launchd won't cut it, is there an alternative approach for not just launching me at login, but also re-launching me if I crash? Obviously, I don't anticipate crashing, but the project requirements I've been handed specify automatic re-launching of this background helper app, and I'd prefer to find a way to satisfy the requirements rather than argue to have the requirement removed. PS: "KeepAlive" is the 10.5 option. In 10.4, it was "OnDemand", which is now deprecated.

Launchd Agents, Login Items, and Tiger

site_archiver(a)lists.apple.com Delivered-To: darwin-dev(a)lists.apple.com Hi, Any help (including alternative suggestions) is much appreciated. Thanks, --Mike _______________________________________________ Do not post admin requests to the list. They will be ignored. Darwin-dev mailing list (Darwin-dev(a)lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/darwin-dev/site_archiver%40lists.app… Let me start by saying that I've read the excellent TN2083, but I didn't find that it answered my question. Here's the problem I'm trying to solve. I hope that perhaps somebody can help suggest a solution (and/or tell me if the solution I propose below will work). I have a little user agent application (written with Cocoa) that runs as a primarily-faceless application (it has a Status Item in the menu bar, but that's about it). It will be installed per-user, and needs to launch when the user logs in to a normal GUI session. As well, if it should crash, I would like it to be re-launched. The application needs to support Tiger and Leopard. So, obviously, I can do this with launchd on Leopard. I can get launched at login with a Login Item on Tiger, but I don't get the automatic restart. So, what I'm wondering is: is there any way to use launchd to give me the automatic restart that I need, on Tiger? One thing I had thought of doing is to have myself launched as a Login Item, but once launched, to *add myself* to launchd's list so that if I should crash, I'll get re-launched. I haven't tried this solution yet, so perhaps somebody can save me a little time if you already know it won't work. This email sent to site_archiver(a)lists.apple.com

Nope. Everything's Leopard. I didn't do a archive and install, though... Just upgraded. But, that shouldn't make a difference, should it? _______________________________________________ Do not post admin requests to the list. They will be ignored.
