Error on the taskDaemon script: 'NoneType' object has no attribute 'sleep'

With python 2.5.2

The line is time.sleep in the following method:

    def run(self):
        while not self.st:
            w = worker(self.log)
            w.start()
            time.sleep(self._inter)
        print "thread stopped"

time should be the time module. I see no other definition in the source code. Can you please insert a print statement right after the imports:

print time

Just to check if it is being correctly imported?
I'm really unable to reproduce this...

[pferreir]

Any news on this?

[sylvestre]

Sorry, I did not get any email from your bug tracker to tell me that you have push a comment.

print straight after the import of time it giving:
<module 'time' from '/usr/lib/python2.5/lib-dynload/time.so'>

[pferreir]

Did the situation change with the new, non-corrupted EGGs?
Can you try placing some print time instructions around and see if the value changes? I really can't reproduce this.

[sylvestre]

I did a fresh install with the new egg and I can reproduce it anytime...

[pferreir]

Have you followed my suggestion of adding the prints?

[sylvestre]

I did but nothing relevant.
In
/usr/lib/python2.5/site-packages/cds_indico-0.97b-py2.5.egg/MaKaC/common/timerExec.py
I did that:
23:print "after import ",time
[...]
597: print "==== before time.sleep ",time
598: time.sleep(self._inter)
599: print "==== after time.sleep ",time

I only see:
after import <module 'time' from '/usr/lib/python2.5/lib-dynload/time.so'>

[pferreir]

Well, this is too weird, almost paranormal, since we've been using the taskDaemon with no problems at all, and time should be shared among threads.
Does this happen every time you try to run the daemon?
Maybe you don't get to see the prints because of it happening on a different thread.
Could you try writing to a file instead? I can't really reproduce this...

[sylvestre]

This happens all the time.

I tried with a file. It is interesting...
replacing the display by
FILE = open("/tmp/plop","w")
FILE.writelines("after import "+str(time))
make the software crashes before with an unrelated error:

For information, I still have the issue with the rc1.

Is this still happening? We'd like to close it ASAP.

[pferreir]

Closing for lack of feedback. Impossible to reproduce here.
