[dpdk-dev] [PATCH 0/4] Reorganise Travis jobs

[David Marchand]

This series tries to make the travis configuration a bit easier to read,
then drops jobs that are not essential or functional duplicates in the
hope we can give some oxygen to the robot who seems to lag quite a bit
and can't catch up.

[dpdk-dev] [PATCH 1/4] ci: remove unnecessary dependency on Linux headers

[David Marchand]

Following removal of kmod compilation, we don't need to install
linux-headers anymore.

[David Marchand]

Reading https://config.travis-ci.com/ and using
https://config.travis-ci.com/explore to check changes, we can cleanup
some warnings reported by the config validation options in Travis.

[dpdk-dev] [PATCH 3/4] ci: use an explicit list of Travis jobs

[David Marchand]

Maintaining the .travis.yml requires some knowledge of how Travis
computes the jobs list (combination of os: arch: compiler: etc...).
Let's switch to an explicit list to find all jobs at a glance.

To enhance readability, jobs have been sorted per arch/compiler with
comments to isolate blocks.

Setting required_packages for aarch64 native jobs is unnecessary,
the global addons: values are the same.

This commit does not change the jobs list (21 jobs in total).

[dpdk-dev] [PATCH 4/4] ci: reorganise Travis jobs

[David Marchand]

Let's prune the jobs list to limit the amount of time spent by the robot
in Travis.

Since meson enables automatically the relevant components, there is not
much gain in testing with extra_packages vs required_packages only.

For a given arch/compiler/env combination, compilation is first tested
in all jobs that run tests or build the docs or run the ABI checks.
In the same context, for jobs that accumulates running tests, building
the docs etc..., those steps are independent and can be split to save
some cpu on Travis.

With this, we go down from 21 to 15 jobs.

Note: this patch requires a flush of the existing caches in Travis.

In general, I think the idea with required vs. extra was to have a build
that did the minimum required, and one that did all the packages (to
allow a minimum vs. full DPDK).

At least, that's from
http://mails.dpdk.org/archives/dev/2019-January/124007.html

Not sure if that's still something anyone cares about.

Much easier to follow,  I had no issues adding ppc64le jobs.
All my travis jobs ran fine.

LGTM  (the series)

I think the benefit of a minimum build is to have a quick report,
and easy to setup.

Given that Travis knows how to satisfy the dependencies,
and that we must wait for all jobs to finish,
I don't see any benefit of a minimal setup.

Yes, Travis serves as a first gate when submitting patches.
But since Travis is best effort/free, we can't have a full coverage.

This minimal setup also tests that dpdk dependencies are correct.
If a change makes something rely on libX and libX is in the packages
always installed in Travis, the missing dependency would not get
caught.

But here, this adds too many jobs.

UNH, Intel and other CIs should step in and fill this kind of gap.

Maybe it is already covered, the best is to ask, so sending to ci@dpdk.org.

For the CI guys, which packages are installed on the systems/vms that
do compilation tests?
Is it possible to have a summary of the different setups?

Since I only have this commitlog to update, I intend to push the
series with the following addition:

Example on a job in master:
https://travis-ci.com/DPDK/dpdk/builds/149537002/config

Build config validation:
root: deprecated key doc_packages (anchor on a non-private key)
root: deprecated key build_32b_packages (anchor on a non-private key)
root: deprecated key libabigail_build_packages (anchor on a non-private key)
root: deprecated key extra_packages (anchor on a non-private key)
root: deprecated key aarch64_packages (anchor on a non-private key)
root: key matrix is an alias for jobs, using jobs

For the "(anchor on a non-private key)" warnings, the Travis
documentation [1] recommends prefixing private keys with _ (Travis
schema is available at [2]).

The use of the "matrix" key is allowed, but it is just an alias to the
"jobs" key.

For our compile tests, we compile with pretty much all dpdk
dependencies that can easily be installed from the distro's repository
(the dependencies we installed are based on the meson output). The
thought process was to test compiling as much of dpdk as possible
(with constraints mentioned before).

Here are the dependencies we install on some of the setups:

Ubuntu 18.04: make gcc ninja-build pkg-config libnuma-dev
librdmacm-dev librdmacm1 rdma-core libelf-dev libmnl-dev libpcap-dev
libcrypto++-dev libjansson-dev
(meson installed with pip)

CentOS 8 and Fedora 31: diffutils gcc make ninja-build meson
pkg-config numactl-devel librdmacm rdma-core-devel
elfutils-libelf-devel libmnl-devel libpcap-devel jansson-devel

openSuse Leap 15: gcc make ninja pkg-config libnuma-devel librdmacm1
rdma-core-devel libelf-devel libmnl-devel libpcap-devel
libjansson-devel
(meson installed with pip)
