Ideally, I would prefer we land something minimal and working in mainline soon,
then further collaborate on changes that clean up code and enable more features.

My end-game is to have P4 Streams working in git-p4, and maybe LFS-like support
that uses p4 as the backend. It would be great to not be the only one
spending effort
in that direction.

I have similar goals.  I would love to get the smallest set of non-breaking
changes in that allows the program to basically work with Python 3.5+.

My rush has been because I need to use git-p4 for work and have been
working
on the project at the office.  Once I reach a point where I am able to
generally work (when t9800 is complete) I'll really not be free to spend
too
much work time on the project, but I am eager to see this through!

I'm in a similar situation, but we use p4 Streams and so I actually need further
development before being able to make a full switch. I am given more liberty
in terms of how much work time I can dedicate to this, though.

Given the situation, can you give my patch set a try in your work environment?
It is currently passing everything except t9824-git-p4-git-lfs.

I downloaded your code and it looks like it works for Python 2.7.  I'm 
seeing errors with the following tests:

The last test was a breaking test that stopped the test make.

If you're OK with it, I would prefer that we work from my version as a base and
add some of your quality-of-life enhancements on top. I can do the merges myself
if you are pressed for time.

Thanks,
Yang

I am not a Python developer and my code is further behind than yours, so
it makes complete sense to use yours as the base.
