My application implements the NSApplicationDelegate method
-application:openFile: in its app delegate. There seems to be a problem new
to OS 10.8 where after receiving the apple event to open a file, five
seconds pass before some kind of internal timeout is hit, a response is
sent to the apple event, and the calling app (e.g., applescript editor)
proceeds.
In detail, here's what I see. After application:openFile: returns YES, I
can see that -[NSAppleEventManager suspendCurrentAppleEvent] is called:
#0 0x00007fff8f07b5ed in -[NSAppleEventManager *suspendCurrentAppleEvent*]
()
#1 0x00007fff8f90458e in -[NSApplication(NSAppleEventHandling)
_handleAEOpenDocumentsForURLs:] ()
#2 0x00007fff8f903b55 in -[NSApplication(NSScripting)

#3 0x00007fff90770cac in __invoking___ ()
#4 0x00007fff90770b47 in -[NSInvocation invoke] ()
#5 0x00007fff90770d19 in -[NSInvocation invokeWithTarget:] ()
#6 0x00007fff8f10121c in -[NSScriptCommand _sendToRemainingReceivers] ()
#7 0x00007fff8f1014c6 in -[NSScriptCommand executeCommand] ()
#8 0x00007fff8f11983a in -[NSScriptingAppleEventHandler

#11 0x00007fff93844f68 in aeDispatchAppleEvent ()
#12 0x00007fff93844dc9 in dispatchEventAndSendReply ()
#13 0x00007fff93844c89 in aeProcessAppleEvent ()
#14 0x00007fff8c141e29 in AEProcessAppleEvent ()
#15 0x00007fff8f6b22a6 in _DPSNextEvent ()
#16 0x00007fff8f6b1862 in -[NSApplication
nextEventMatchingMask:untilDate:inMode:dequeue:] ()
#17 0x00007fff8f6a8c03 in -[NSApplication run] ()
#18 0x00007fff8f64d656 in NSApplicationMain ()
#19 0x0000000100001d7c in main (argc=3, argv=0x7fff5fbff7c0) at main.m:23
After five seconds, -[NSAppleEventManager resumeWithSuspensionID:] is
called:
#0 0x00007fff8f07b6be in -[NSAppleEventManager *resumeWithSuspensionID*:]
()
#1 0x00007fff8f90585f in __block_global_1 ()

#11 0x00007fff8f6a8c03 in -[NSApplication run] ()
#12 0x00007fff8f64d656 in NSApplicationMain ()
#13 0x0000000100001d7c in main (argc=3, argv=0x7fff5fbff7c0) at main.m:23
Evidently, some kind of timeout was reached since resumeWithSuspensionID:
is called from a timer and it is always very close to 5 second between my
application:openFile: method returning and resumeWithSuspensionID: being
called.
After this, things proceed normally: whatever applescript invoked "open
file ..." continues at the next statement. There don't appear to be any
errors--it just times out waiting for something.
I turned on AEDebugSends and AEDebugReceives. Here's what I see up to the
timeout:
Aug 23 21:26:05 George-Nachmans-MacBook-Air.local iTerm[4819] <Info>:

(_aeMachPortCallback()/AEMach.cp #643) main
Aug 23 21:26:05 George-Nachmans-MacBook-Air.local iTerm[4819] <Notice>:

Direct Parameter: /Users/georgen/Library/Application
Support/iTerm/version.txt
Receivers: (null)
Arguments: {
"" = "/Users/georgen/Library/Application Support/iTerm/version.txt";
}
Then, after the timeout I see this (which is logged because I also set
NSScriptingDebugLogLevel to 1):
2012-08-23 21:26:36.347 iTerm[4819:707] Result: <null>
My openFile: method doesn't do anything besides return YES. Is there
something else I need to do to make the framework happy?
Thanks,
George
