amp slave does not exit

[yippi]

When I run elisa and play an audio file, then exit elisa while the audio is playing I notice that it leaves behind a amp slave process. It doesn't seem to exit when elisa exits. The slave process running is this:

/usr/bin/python2.4 /usr/lib/python2.4/vendor-packages/elisa/plugins/amp/slave.py

I am attaching the stack trace of the hung process.

Does Elisa itself exit properly?

[yippi (brian-cameron)]

Most of the time elisa exits properly. For example, if I run elisa from a terminal window, start playing an audio file, then exit, it usually exits and the prompt returns to the terminal. However, even when elisa exits properly, the slave process is left behind.

Sometimes when I run elisa, it hangs. Sometimes when elisa hangs, the song continues playing - but not always. A bit odd.

I notice that whether the slave uses sys.exit() or os._exit() does not seem to make a difference with this. See bug #345633.

I wonder if that could be a python 2.4 specific problem.

[yippi (brian-cameron)]

Note, this isn't a Python 2.4 specific problem. I've built and tested elisa on Solaris using both Python 2.4 and 2.6 and I notice the same problem.

If there is anything I can do to help debug what might be going on, please let me know. I'm not very familiar with the amp slave or how it should be exiting. Perhaps if we added some debug statements to the code we could track down what is happening? If you could advise where to add debug statements or if you have other suggestions, then I would be happy to research this further.

Also, I believe that Sun provided Fluendo with some Solaris machines, so it might be possible for you to test and see the behavior as well if this is Solaris specific.

Is that still valid with Moovida 1.0.8?

[yippi (brian-cameron)]

Thanks for reminding me to re-test this. I just tested with moovida 1.0.8 and this problem no longer happens.
