524177 - winmo emulator uncaught exception triggered by file contention

Status: RESOLVED WONTFIX

(Tamarin Graveyard :: Tools, defect)

Description

[Dan Schaffer]

The winmo emulator python script wmemulatorshell.py has some io contention problems when run on the test machine with 16 concurrent emulators and python threads.  Uncaught exceptions will cause the retry logic to stop.  There have been a couple of spots in the script lately causing intermittent failures.

Reopening bug as I don't think this is completely resolved. There was a recent failure on windows mobile:

 ERROR: cannot find exit code file share11/media/abcasm_coverage_A.abc.exitcode 
 Traceback (most recent call last): 
 File "wmemulatorshell.py", line 244, in <module> 
 (res,sysout)=runTest() 
 File "wmemulatorshell.py", line 195, in runTest 
 os.unlink(dir+"/tamarin-redux/lock") 
 WindowsError: [Error 2] The system cannot find the file specified: 'emulator/share11/lock'
