From: Bill O'Donnell @ 2018-05-04 14:34 UTC (permalink / raw
  To: fio

Many distributions are moving to python3 by default.  Here's
an attempt to make the python scripts in fio python3-ready.

Conversion was facilitated with automated tools. A few areas
were hand fixed: remove superfluous parentheses introduced by
2to3 converter in print function calls, shebang modifications
to use environment variable for python version, and byte-string
decode correction in steadystate_tests.py following 2to3
conversion.

The modified scripts pass rudimentary testing when run under
python2.7 as well as python3.

Apparently there's a distro or operating system that discourages or
doesn't like every type of python #! line you can come up with (see
https://github.com/axboe/fio/commit/60023ade47e7817db1c18d9b7e511839de5c2c99
). For now let's leave it at #!/usr/bin/python2.7 but add a comment
beneath saying that the script actually works with python2 or python3 (also
see the discussion in https://www.spinics.net/lists/fio/msg06746.html
, https://www.spinics.net/lists/fio/msg06748.html and
https://www.spinics.net/lists/fio/msg06977.html ). Distros can then
use a uniform tool at packaging time to convert all the scripts to
whatever their preferred syntax is.

I wonder if some of these imports are actually redundant and could be skipped...

Isn't this one already python 3 compatible? (see the thread in
https://www.spinics.net/lists/fio/msg06709.html for where Kris
converted it).

Agreed.

Indeed, these amount to overdone future-proofing by the automated converter.

Ah...Yes. Kris' changes along with bb36ebad32a8 make my changes unnecessary.

I'll fix a version 2 of the patch.

* [PATCH v2] make fio scripts python3-ready
  2018-05-04 14:34 [PATCH] make fio scripts python3-ready Bill O'Donnell

From: Bill O'Donnell @ 2018-05-04 19:43 UTC (permalink / raw
  To: fio

Many distributions are moving to python3 by default.  Here's
an attempt to make the python scripts in fio python3-ready.

Conversion was facilitated with automated tools. A few areas
were hand fixed: remove superfluous parentheses introduced by
2to3 converter in print function calls, shebang modifications
to use environment variable for python version, and byte-string
decode correction in steadystate_tests.py following 2to3
conversion.

The modified scripts pass rudimentary testing when run under
python2.7 as well as python3.

Signed-off-by: Bill O'Donnell <billodo@redhat.com>
---
v2: Remove unnecessary changes to fiologparser_hist.py as
    its conversion has been covered in earlier patches.
    Keep shebangs at previous python2.7 state. Remove
    superfluous imports.

IMHO these imports are needed only for python < 2.7.
I do not think it worth it to support such an ancient versions.
The same for the other files.
