The module os does not have the stat_float_times function, even though the Jython documentation lists it as an available function.

This directly impacts django 1.3+, as django uses this function for collecting and serving static content. I'm logging a patch to django to work around this function not being available, but I still feel that jython should at least provide a dummy implementation, to maintain compatibility where possible.

Interestingly, the cpython people want to deprecate the stat_float_times function.

Remove os.stat_float_times

Please can you link to the django code that uses this?
msg7654 (view) Author: Josh Smeaton (smeatonj) Date: 2013-02-10.00:22:20 was accepted into core, meaning the dependency is now resolved dynamically. This is the only spot in django that makes use of stat_float_times. I think it'd be fairly safe (in regards to django at least) to follow the python 3 direction.

I set this as a doc issue, since really we probably won't be adding a stat_float_times function if it is going away in Python 3.

As of, os.stat and os.lstat now return floating point times, if available, given that they now use Java 7 file attributes. os.fstat also returns floating points times, but with the fraction set to zero since the underlying JNR posix support doesn't make the nanosecond fields available in the returned stat_t structure.

It would be trivial to support this function, so we probably should.

So, we are removing the stat_float_times function, or updating the docs?

I'd go with Jim's last idea: "probably should" support.

We aim to be the same as CPython if we can be, and there aren't independent documents for Jython anyway.
