Native app logging causes native activities to hang/crash #29

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Launch a native app that does any kind of regular logging (e.g. sprintf, 
cout)
2. App will fail silently (console app) or display a beach ball (GUI app) 
depending on how much logging it does

What version of the product are you using? On what operating system?
IS 1.3+, OS X

Here is an example:
I created a light-weight activity that starts up a python script. This script 
logs every second, and I simply tailed the log to see when the python script 
stopped responding.

In the first test I had it logging to stdout and to a file. The activity logged 
to the file for 76 seconds and then stopped. I let it run for 11 minutes before 
stopping the activity via I.S.

In the second test I had it only log to the file. I ran the test for almost 30 
minutes and the script was logging the entire time.

In the third test I used print(..) to log one line to stdout at the beginning 
of execution, then only logged every second to the file. I ran this test for 40 
minutes and the log file was being written to the entire time.

Attached is the activity I created along with the logs created by the python 
script for each test. script.py is the python script that I wrote, it has 
comments indicating which lines were uncommented for the various tests. The log 
files were being written to my controller root directory 
(/Applications/interactivespaces/controller/example.log in this case). I am on 
OSX 10.7.5 using I.S. 1.4.0

Controller log showing the activity being re-uploaded and started/stopped for 
each test:
