I have a large body of Python code which runs on many different (Unix) machines concurrently. Part of the code lives in one place, but most of it lives in directories which I find at runtime. I only have one copy of each Python source file and I think I'm hitting a race condition where two hosts attempt to import the same module at the same time. My import fails on one of the machines and the following exception is thrown: EOFError: EOF read where object expected My hypothesis is that there's contention between the two (or more) hosts when the module's .pyc file is generated.
Possible solutions I see: 1) Running a cron job before my code executes which compiles all the python source first. 2) Making separate copies of all the .py files for each host running the code - I'd rather not do this, it seems like a big pain. 3) Inhibiting the generation of .pyc files altogether if that's even possible - I saw a PEP for a possible -R flag (http://www.python.org/ dev/peps/pep-0304/) but I don't think it has been added to a released version of Python yet plus I am stuck with Python 2.4 for the time being. Any and all help appreciated. Thanks. -- http://mail.python.org/mailman/listinfo/python-list
