I'm a bit unsure if this is the right list -- sorry if not -- but the
archives are well populated with related stuff, so I'm encouraged, yet
not quite this stuff, so I ask:
My program (a Finder plug-in, actually) works fine in Tiger, but logs
messages like this in Leopard:
11/30/07 2:45:55 PM SCPluginUIDaemon[14305] *** CFMessagePort:
bootstrap_register(): failed 1100 (0x44c) 'Permission denied', port
= 0x3d03, name = 'org.tigris.scfinderplugin.overlaymessage'
See /usr/include/servers/bootstrap_defs.h for the error codes.
11/30/07 2:45:55 PM com.apple.launchd[145]
(0x111000.SCPluginUIDaemo[14305]) Check-in of Mach service failed.
PID 14305 is not privileged: org.tigris.scfinderplugin.overlaymessage
The program misbehaves in user-visible ways as well (sometimes fails
to badge Finder icons), which I suspect are caused by this situation,
since that's what this port is all about.
It's a fairly decent message, as messages go: I think I grok a fair
bit about what it's telling me (short form, "you can't do that").
Since it works in Tiger, it appears the security bar was raised in
Leopard (a good thing in general, I suppose). But what's not clear to
me is, what do I do about this? I'm legit! How do I prove that?
Must I transform my program into a set-uid? Is there another
communication technique I should be using in order to avoid the need
to become All Powerful?
The process is a sort of a daemon: that is, it's an autonomous,
faceless process (not formally a daemon, no monkey shines with I/O
streams or process groups or identity). It's launched by side effect
when Finder first materializes its contextual menu; hence, it has the
same identity as Finder, which is to say "whoever you are." We have
an ordinary Finder contextual menu plug-in as well, which does that
launching thing, and then chats with the daemon over this port. We've
considered (for other reasons) rearranging the daemon into a
LaunchDaemon/Agent ... has that time now come, is that the only way
out of these woods?
