Well, I've had some patches up at http://bugs.python.org/issue6626 for
over a week now, and my updated version should have identical
semantics to the current module, just with the module's *actual*
behavior clear to anyone reading the code, some serious edge-case bugs
fixed, and a general performance improvement.
I'd like to make some further changes, particularly in which types and
extensions the module knows about, to bring it up to date, and ideally
even to remove the dependency on an Apache install, but I'd like some
discussion and advice about it.
I have some other questions: How does one deprecate part of a standard
library API? How can we alert users to the deprecation? When can the
deprecated parts be removed?
I don't want to just give up on this, because I put more than a day of
time into it, and I really do think the previous code was of poorer
quality than should be in the standard library: I don't want new
Python users reading it and thinking that's just how things are done
around here. But if no one looks at my patches, I'm not sure what more
I can do.
