Thread: CP300beta, OSError: Operation not supported




CP300beta, OSError: Operation not supported
user name
2006-10-23 17:44:33
Hello,
I am traing to update my existing CP2.2.1 application to
work with
CP300beta and seem to have a problem with the new autoreload
feature.
The application so far seems to run fine, but anytime the
autoreload of
the development mode is hit, I get an OSError:

os.execv(sys.executable, args)
OSError: [Errno 45] Operation not supported

I am running python2.4 on an OSX Intel macbook. Might this
be a
specific Apple w/Intel problem? I had no oppertunity to test
the
application under linux or windows (I will try and report
this
tomorrow).

Any help greatly appreciated.

Thanks,
Markus

CP300beta, OSError: Operation not supported

Thanks Christian,
its exactly what I experience.
Do you know if respawning happens in production mode too?
If not one could at least deploy the application already.

Markus

No, respawning does not happen in production mode. ;  Autoreload is off by default in that mode.
