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 [...]
If you don't want pyc files to be created, you could set Unix
permissions such that Python cannot write to the directory.
