From: Josef Bacik <jbacik@fb.com>

This patch does the nuts and bolts of grabbing fio results and storing
them in a database in order to check against for future runs.  This
works by storing the results in resuts/fio-results.db as a sqlite
database.  The src/perf directory has all the supporting python code for
parsing the fio json results, storing it in the database, and loading
previous results from the database to compare with the current results.

This also adds a PERF_CONFIGNAME option that must be set for this to
work.  Since we all have various ways we run fstests it doesn't make
sense to compare different configurations with each other (unless
specifically desired).  The PERF_CONFIGNAME will allow us to separate
out results for different test run configurations to make sure we're
comparing results correctly.

Currently we only check against the last perf result.  In the future I
will flesh this out to compare against the average of N number of runs
to be a little more complete, and hopefully that will allow us to also
watch latencies as well.

Given that /usr/bin/python will some day point to python 3 instead of
python 2 (and all of the grief that will ensue when someone has to run
fstests on, say, 2019 and 2021-era Linux distros at the same time when
they finally start pointing /usr/bin/python to 3.x), I think we should
avoid relying on /usr/bin/python to run our fstests scripts.

ISTR in the previous thread that python 2.7 was a requirement for the
scripts below, so find the python2 binary instead.  It might even be a
good idea to have a _require_python_version helper to check that the
interpreter exists and that it's of a specific vintage.

Should we put this in common/perf in case we start adding more
performance testing helper functions?  common/rc is already a mess.

I'd put the requirements checking into a separate
_require_fio_results_dependencies() helper because any funcion call
starting with '_require' signals (to me anyway) that we're checking for
required software and will _notrun if we don't find it.

Test initialization functions, by contrast, only get run once the
_require* calls are finished and we therefore know that we have all the
external pieces we need to run the test.  If init doesn't succeed, the
test can _fail.

My scripts run fine on both 2 and 3.  I'm worried about other distro's, does
everybody do the python2/python3 thing?  If so then I'll just default to
python2, I just have no idea if that's a thing beyond Fedora/RHEL.

Agreed, I'll fix it.  Thanks,

Debian & Ubuntu both have python2/python3 binaries in their oldest
stable releases.

ISTR /usr/bin/python -> python2.7 and /usr/bin/python2 -> python2.7

Good to hear that the scripts work on both, though.

Though that adds the extra twist of what about scripts that have been
carefully written to work on either...

...I guess a solution to that could be a _require_python that sets
PYTHON_PROG.  If you "_require_python $ver" then you'll get PYTHON_PROG
set to an interpreter that's compatible with $ver, or PYTHON_PROG is set
to /usr/bin/python if you don't provide a version number at all.

(Yuck yuck yuck...)
