Hello all,

At this morning's release meeting (minutes coming soon from John), we
briefly discussed the state of the regression testing for stable
releases and agreed we need to formalise the process.

At the moment we have a firm commitment from Intel and Mellanox to test
all stable branches (and if I heard correctly from NXP as well? Please
confirm!). AT&T committed to run regressions on the 16.11 branch.

Here's what we need in order to improve the quality of the stable
releases process:

1) More commitments to help from other companies involved in the DPDK
community. At the cost of re-stating the obvious, improving the quality
of stable releases is for everyone's benefit, as a lot of customers and
projects rely on the stable or LTS releases for their production
environments.

2) A formalised deadline - the current proposal is 10 days from the
"xx.yy patches review and test" email, which was just sent for 16.11.
For the involved companies, please let us know if 10 days is enough. In
terms of scheduling, this period will always start within a week from
the mainline final release. Again, the signal is the "xx.yy patches
review and test" appearing in the inbox, which will detail the
deadline.

Comments?

Hi Luca,
I discussed with Thomas about it.
I don't know how much extra effort for the stable maintainers it would be,
but I wonder if there could be a XX.YY.z-rc tarball.
That would be
a) a more clear sign what people are used to test
b) easier to integrate as I assume quite a bunch of tests will usually
start rebasing on tarballs instead of directly from git.

If you think everyone can derive from git easily I'm fine, I just wondered
if a proper -rc tarball might be more comfortable for the testing entities.

Do you have a list of steps (test-cases?) which are carried out for stable
regression? I think it is necessary in order to understand the effort involved
before committing to it.

Again, I believe it depends on what needs to be tested (and how) in order to
comment on "how much time is required".

This is left intentionally vague - apart from the unit tests, we don't
have a public formal "production" test suite, so each company has its
own, that in general is tailored to test their own product.

For example, AT&T builds a virtual router, and the regression tests
cover the functionality of that product that are implemented via DPDK.

I imagine companies developing NICs and PMDs will have regression tests
that exercise those network cards in production. Likewise an enterprise
distribution like Ubuntu can test their build of OVS, for example.

So what we are asking is, for those companies/groups that use DPDK, if
they can help us test that the stable candidate releases are working
correctly with their products/hardware/projects. The hope is that among
everybody there is enough coverage of various functionalities and PMDs.
I'd love to have a formalised, public, all-encompassing test suite
(something that was discussed in Dublin the year before last I believe)
but we have to work with what we've got.

Does this make sense?

See above - it will vary from stakeholder to stakeholder, and that's
why I asked if that timeframe is workable.

I think that's a good idea, and something we can consider for the next
release cycle - the tools to push rc to mainline should work just the
same for the stable repo.

Thanks for taking the time to explain it. Now, it is much clearer in my mind.

Yes, I confirmed that on call on behalf of NXP. But...

> confirm!). AT&T committed to run regressions on the 16.11 branch.

Not until 17.05 did NXP's first driver started appearing in the DPDK upstream releases. Somehow, I misunderstood your request for 16.11 with 17.11 stable.

That's fine - the 17.11 branch is also getting ready for release (see
relevant threads), and 18.02 will soon as well.
