#5533: Recompiling .spyx files changes class
---------------------+------------------------------------------------------
Reporter: rhinton | Owner: cwitty
Type: defect | Status: new
Priority: major | Milestone:
Component: misc | Keywords:
---------------------+------------------------------------------------------
Apparently, recompiling a .spyx file creates a new module and/or creates a
new dummy class. This gets in the way of pickling. For example, start
from a command prompt and follow the instructions using the attached
junk7.spyx.
{{{
sage # at the command prompt, start Sage
sage: load 'junk7.spyx'
sage: # make an insignificant change to junk7.spyx so it will recompile...
sage: load 'junk7.spyx'
sage: MyClass().greet()
Greetings!
sage: import pickle
sage: fi = file('junk7.pjr', 'w')
sage: pickle.dump(MyClass(), fi)
sage: fi.close()
sage: exit # returns to the command line
sage # now restart sage from the command line
sage: load 'junk7.spyx'
sage: import pickle
sage: fi = file('junk7.pjr', 'r')
sage: tmp = pickle.load(fi)
---------------------------------------------------------------------------
ImportError
...
ImportError: No module named _home_ryan_uva_prng_well_sage_junk7_spyx_1
}}}
So the error is trying to import the module. Apparently compiling a .spyx
file creates a new Python module each time? Other than exiting Sage every
time I want to recompile, I don't see a way around this problem -- or a
way to fix it.
