panther time out bug (was: panther weirdness)


  • Subject: panther time out bug (was: panther weirdness)

Here's an update, and a plea for help. Can someone with os 10.3.3 run this script (more than once - the first time it should work fine) and let me know if it waits 2 minutes to finish the second time?

It turns out that after leaving my longer script running during lunch I returned to find this error, which seems to confirm that there's some problem with scripts not returning after they are done.

Errors: {
NSAppleScriptErrorBriefMessage = "AppleEvent timed out.";
NSAppleScriptErrorMessage = "FileMaker Pro got an error: AppleEvent timed out.";
NSAppleScriptErrorNumber = -1712;
NSAppleScriptErrorRange = <00000501 0000001a >;
}


Here are handy java commands to make it easier:

copy text of script to a file named testas.java

to compile:
javac -classpath .:/System/Library/Java testas.java

to run:
java -classpath .:/System/Library/Java testas

Grateful in advance,
Seth

The output should be something like
myScript.executing:
tell application "Finder"
get the name of every item in the desktop
end tell

Elapsed time = 121.149 seconds
Starting list of items on the desktop:
<list of itmes on your desktop>

I recently upgraded to panther and some scripts I ran in the past using
java now hang or take an unusually long time (20 min?) to run.

In attempting to debug, I've figured out that the scripts seem to be
waiting for (2 * timeout) seconds before returning control to java.

Interestingly enough, the script included below runs fast the very first
time I run it after restarting my machine, but after that it always takes
2 minutes to run. (default applescript timeout is 1 minute) If I wrap the
script in 'with timeout of 5 seconds ... end' then the script will finish
in just over 10 seconds.

The main script I'm trying to run involves Filemaker and I think it hangs
completely, but it's possible that it's waiting 2 minutes many, many,
times and so I never see it finish. (I've waited over 1/2 hour).

Any idea of what could be the problem? I'm running os 10.3.3
