Doesn't work on Debian, because using is_alive instead of isAlive

[Mathieu Parent]

Binary package hint: usb-creator

using trunk version, compiled on Debian testing, I have the following errors:

This is due to the use of is_alive method which is not available in python < 2.6 (see http://groups.google.com/group/robotframework-devel/msg/7d1ec233dc392670?pli=1).

Solution: in usbcreator/install.py, replace all is_alive by isAlive.

Mathieu, could you please clarify the steps taken to get this error. If it was an error in compilation or when using usb-creator. If you could attach a patch for usbcreator/install.py, this bug can be triaged. Also please test the latest code and post if this is still an issue.

[Mathieu Parent (math-parent)]

The bug is still here. See attached patch.

Both is_alive and isAlive are in docs (see http://docs.python.org/library/threading.html#threading.Thread.is_alive). But isAlive() is more conform to other methods: isDaemon, setDaemon, ...

[Dimitri John Ledkov (xnox)]

Confirming the issue. Will work on pushing this to trunk.

[Mathieu Parent (math-parent)]

New version of the patch (made with bzr diff).

[Victor Vargas (kamus)]

I have set status to triaged for now, so please be pacient and wait a response of usb-creator developers. Thanks!

[Dimitri John Ledkov (xnox)]

Well, we use python3 now.
