Status of python3 for fio?

Status of python3 for fio?

[Eric Sandeen]

Fedora is moving more and more towards python3.  (TBH, as a non-python
expert, I don't know all the details...)

I see that python2.7 is hardcoded in several scripts, and Jens though
there were possibly some patches "floating out there" to switch
the various scripts to python3.  Does anyone know the status of
this work?

Thanks,
-Eric

fiologparser_hist.py was made Python 3 compatible but it's unknown
whether all the other scripts are as ready (I'm going to guess no). The
hope is that eventually all scripts will be made Python 3 ready but it
will be up to distros to rename the interpreter to use to one they
like at packaging time because it's impossible to satisfy all distros
with a single interpreter line...

You can see the rationale behind the python2.7 rename here:

Ok, thanks.  So, I'm going to try using the automated tools to make them
python3-compatible.

I'm no python guru, so I hope that if I take a semi-dumb approach and send
patches it'll at least be a starting point, if not perfect.

Thanks,
