tox -e storage-py37
...
1448 passed, 103 skipped, 100 deselected, 322 xfailed, 236 warnings in
71.40 seconds
## Today
git checkout
tox -e storage-py37
...
1643 passed, 103 skipped, 100 deselected, 105 xfailed, 82 xpassed, 107
warnings in 79.72 seconds
Change:
*passed: +195*
*skips: 0*
*xfail: -217*
*xpass: +107*
*warnings: -129*
## XPASS
107 xpass are most likely easy fix, just remove the xfail() mark from the
test or parameter.
Patches should not introduce new XPASS, you should remove all xfail() marks
that a patch
fixes. To test that your patch do not introduce new XPASS, add this option
to tox.ini:
[pytest]
xfail_strict = True
This converts XPASS to FAIL.
These modules need to be fixed:

## xfail
We must fix these xfail before we can run OST. If we start running OST
we will waste days debugging OST. Debugging failing tests is 1000X times
faster.

## Skips
Skips should be used only when test cannot run on specific environment,
but I think we have some wrong skips that should have been xfail.

See "warnings summary" in pytest output.
Looks less useful, report issues in packages we use instead of issues in
our code.
But this may be an issue using old versions of packages.

I agree about the speed, OST is awfully slow, almost unusable. But other than that, not
really, I discourage you from neglecting functional fixes and just focuse on unit tests.
It is important to fix actual functional problems
Coincidentally, just now I got a working OST on py3/RHEL8 just with a couple of
workarounds/skips. So we should soon be able to have this (slow) safeguard in place and
we’ll be able to eliminate py2/el7 code.
Thanks,

It is important to fix actual functional problems
We are focusing on small and fast functional tests doing real flows with
(mostly) real storage.
I think this give be the best value. Being able to verify changes in
seconds means you can
move fast - safely.
The most important actual issue we have now is tests failing on pyhton 3,
for example
block storage tests:
https://gerrit.ovirt.org/q/topic:py3-blocksd
When these tests will pass, there is a chance that block storage will work
in OST.
A bigger problem is code without any tests like the tasks framework, SPM
flows and
legacy storage flows. We work now on the tasks framework:
https://gerrit.ovirt.org/q/topic:py3_task
We also worked on the outOfProcess module which is the foundation of all
file based
storage domains:
https://gerrit.ovirt.org/q/topic:py3-oop
This work reveled 2 bugs in ioproess, one fixed now:
https://gerrit.ovirt.org/q/topic:ioprocess_access
Coincidentally, just now I got a working OST on py3/RHEL8 just with
a
couple of workarounds/skips. So we should soon be able to have this (slow)
safeguard in place and we’ll be able to eliminate py2/el7 code.
We need to keep python 2.7 code until we finish porting to python 3, and
maybe later.
It will be hard to support 4.3 if master code is not compatible with python
2.

1643 passed, 103 skipped, 100 deselected, 105 xfailed, 82 xpassed, 107

# Today (Sep 10)
1724 passed, 105 skipped, 100 deselected, 76 xfailed, 51 xpassed, 98
warnings in 82.43 seconds
Change:
*passed: +81*
*skips: +2*
*xfail: -29*
*xpass: -31*
*warnings: -9*
Some tests require root, but I did not run as root, so we see higher skips
values.
## Python 2 vs python 3
Looking at travis builds:
python 2.7:
https://travis-ci.org/oVirt/vdsm/jobs/583262136
1936 passed, 16 skipped, 100 deselected, 5 xfailed in 211.59 seconds
python 3.7:
https://travis-ci.org/oVirt/vdsm/jobs/583262137
1775 passed, 39 skipped, 100 deselected, 90 xfailed, 52 xpassed, 99
warnings in 198.66 seconds
## Coverage
python 2.7:
storage: 61%
https://jenkins.ovirt.org/job/vdsm_standard-check-patch/11189/artifact/ch...
combined: 63%
https://jenkins.ovirt.org/job/vdsm_standard-check-patch/11189/artifact/ch...
python 3.7:
storage: 59%
https://jenkins.ovirt.org/job/vdsm_standard-check-patch/11189/artifact/ch...
combined: 60%
https://jenkins.ovirt.org/job/vdsm_standard-check-patch/11189/artifact/ch...
