I'm getting an intermittent NameError trying to access a variable set in the
external scope of LoginManager.py . I call my variable _x and set it
directly above where _LogginInUser gets set. I then try to access it
directly above a line that accesses _LoggingInUser gets accessed. I just do
a simple print 'testing=%s'%_x. I get an exception. The line that accesses
_LoggingInUser doesn't.
What gives?
Now get this ... if I change the name to (13x's) _xxxxxxxxxxxxx , it works.
If I then change the name to (6x's) _xxxxxx, it continues to work.
If I then change the name to (3x's) _xxx, it continues to work.
(2x's) _xx works
(1x's) _x doesn't work!!!!
If I change the line near the top of the file from
_xx='sss'
to
_xx=0
and change the print to use a %d I get the NameError.
If I change the line back to _xx='sss' and the print back to a %s I continue
to get the NameError ... even though that exact combination had worked a
minute before!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
If I then change the variable back to have 13x's it starts working again.
Is there some deep problem with the python byte compiler or access control
mangling features of Zope? Or am I missing something stupid?
What in the world is going on?
A.
