Another "gotcha". The "pickle" module seems to be OK with the
translations of "universal newlines" on Windows, but the "cPickle" module
is not. If I pickle
Exception("Test")
send it across the Windows pipe to the parent in universal newlines
mode, and read it with cPickle's
load()
function, I get
ImportError: No module named exceptions
If I read it with "pickle"'s "load()", it works. And if I read the input
one character at a time until I see ".", then feed that to cPickle's "loads()",
that works. So cPickle doesn't read the same thing Python does in "universal
newline" mode.
Is there any way within Python to get the pipe from a child process to the
parent to be completely transparent under Windows?
