Hi Antonin,
when I am commenting the line suggested in the dev_appserver.py, I get
the following error message:
File "/home/mat/prog/google_appengine/google/appengine/tools/
dev_appserver.py", line 782, in __init__
raise IOError(errno.EACCES, 'file not accessible')
IOError: [Errno 13] file not accessible
In the gae sdk version 1.1.8, the line 782 refers to the init function
of a fake file. Should I bypass completely the test for a fake file?
If so, I get version conflicts with other libs.
This is getting really annoying, I really don't understand why pdb is
not available for the DEV side!
Thanks,
Mat
