Package: python-all-dbg
Version: 2.4.4-6
Severity: normal
Hello,
while packaging processing (a python module to use processes like
threads) I've faced a strange error: running tests with python2.{4,5} no
problem, but using -dbg version an error comes out "Fatal Python error:
Invalid thread state for this thread".
Richard (upstream author of processing) kindly provided me a small test
python program to spot the problem (dbg.py attached to this report):
[EMAIL PROTECTED]:~$ python2.4 ~/tmp/dbg.py
parent sleeping ...
child sleeping ...
... child waking
child exiting
... parent waking
parent exiting
[EMAIL PROTECTED]:~$ python2.5 ~/tmp/dbg.py
parent sleeping ...
child sleeping ...
... parent waking
... child waking
child exiting
parent exiting
[EMAIL PROTECTED]:~$ python2.4-dbg ~/tmp/dbg.py
parent sleeping ...
Fatal Python error: Invalid thread state for this thread
... parent waking
parent exiting
[7951 refs]
[EMAIL PROTECTED]:~$ python2.5-dbg ~/tmp/dbg.py
parent sleeping ...
Fatal Python error: Invalid thread state for this thread
... parent waking
parent exiting
[9809 refs]
The behaviour of python2.{4,5} is the intended one, while with -dbg the error
appears.
It could be due to my arch (amd64), an issue on packaging or something deeper
in python code.
Thanks,
Sandro
