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.

v2->v3:
- fixed FioResultDecoder.py so it would translate from older versions of fio
  properly
- fixed FioCompare.py to be a bit more verbose so we know things are working or
  what goes wrong when it isn't.
- fixed fio-insert-and-compare.py so it grabbed the last resulte _before_ we
  insert a new result.
- fixed generate-schema.py to generate an updated schema, including not using
  NOT NULL for all of the fields in case we have some missing fields from older
  versions of fio that we don't care about.
- updated fio-results.sql with the new schema.

v1->v2:
- moved helpers into common/perf
- changed the python stuff to specifically use python2 since that's the lowest
  common demoninator

v3 works fine now (after I deleted the old $RESULT_BASE/fio-result.db
file), thanks!

Can you please add a document file in doc dir to describe this new
framework? And maybe update README file as well for the new prerequisite
packages.

Hmm, please avoid using run_check, it makes reviewing result harder

+failed: '/usr/bin/python2 /root/workspace/xfstests/src/perf/fio-insert-and-compare.py -c test -d /root/workspace/xfstests/results//fio-results.db -n 001 /tmp/7002.json'
+(see /root/workspace/xfstests/results//xfs_4k_crc/perf/001.full for details)

then I need to open 001.full to see why test failed.

I'd prefer just dumping the fio-insert-and-compare.py output to stdout
so that breaks golden image, and we can see the failure reason from the
diff output directly.

+read_iops is a-ok 0.0 0.0
+    write_iops improved: old 25097.55864 new 30469.460103 21.4040797356%
+trim_iops is a-ok 0.0 0.0
+read_io_bytes is a-ok 0 0
+write_io_bytes is a-ok 2097152 2097152
+trim_io_bytes is a-ok 0 0
+read_bw is a-ok 0 0
+    write_bw improved: old 100390 new 121877 21.4035262476%
+trim_bw is a-ok 0 0
+    sys_cpu regressed: old 56.795443 new 65.384168 15.122207956%
+    elapsed improved: old 22 new 18 -18.1818181818%

So I know test failed because "sys_cpu regressed", if I want more
details I can look at perf/001.full file.

(skipped the shining python code :)

Thanks,
Eryu
