[New-bugs-announce] [issue9801] Can not use append/extend to lists in a multiprocessing manager dict

[James Hutchison]

New submission from James Hutchison <jamesghutchison at gmail.com>:

tested python 3.1.2

Man = multiprocessing.Manager();
d = man.dict();
d['l'] = list();
d['l'].append("hey");
print(d['l']);
>>> []

using debugger reveals a KeyError. Extend also does not work. Only thing that works is += which means you can't insert actual tuples or lists into the list. This was all done on a single process
