[PATCH] travis-ci: no longer use containers

[Sebastian Staudt]

Travis CI will soon deprecate the container-based infrastructure
enabled by `sudo: false` in ce59dffb34190e780be2fa9f449f842cadee9753.

Thanks for posting a patch that would serve as a good discussion
starter.  This is not a criticism on your patch, but more is a RFD
to those who helped our use of Travis by contributing to .travis.yml
and ci/.

Don't we need to do some other things so that we can run in vm
environment, rather than in container environment, before doing this
change?  IOW, aren't we doing in .travis.yml something we can do
only in container but not in vm (if there is any), and if so,
shouldn't we be rewriting that something so that we can run in vm?

I know ce59dffb ("travis-ci: explicity use container-based
infrastructure", 2016-01-26) only added "sudo: false" without doing
anything else (e.g. adding things that are only available to those
who run in container), but if we added stuff that are not usable in
vm environment after that commit since then, we need to adjust them
so that we can migrate to the container-based environment, no?

To me, removing that "sudo: false" line seems like the least thing
we need to worry about.  After all, they say that whether we have
"sudo: false" or not, the CI jobs will start running in vm
environment and not in container.  So if the rest of .travis.yml is
ready to run in vm environment, we do not have to do anything ;-).

In short, my question to Lars and SZEDER is, are we already prepared
to be thrown into a vm environment?

If the answer is "yes", then I think removing "sudo: false" is
probably still a good thing to do for documentation purposes
(i.e. showing that we knew we are ready to go through their
migration).

Thanks.

As far as I understand, the container-based infrastructure has only
one benefit over the VMs, the shorter startup time.

OTOH, in VMs we can use sudo, which is not available in the
container-based intra.  This has the benefit that after switching to
VMs, we'll be able to install packages by running 'sudo apt-get
install ...'.  Currently the necessary packages are listed in
'.travis.yml' for Travis CI, while for Azure the whole install command
is embedded in '.azure....yml'.  After the switch we could consolidate
installing packages by 'sudo apt-get...' in
'ci/install-dependencies.sh' for both.

I think we are.  I've run only two builds with this patch, and they
run smoothly and finished successfully.  After you update 'pu' I'll
run more.

I agree.

In fact this was the intention while creating this patch. Although I see
I could have made this a bit clearer in the initial message.

Having a patch that may cause a broken build or other CI problems
seems more appropriate than waiting for Travis CI to flip the switch
and searching for the problem afterwards.

[PATCH] travis-ci: install packages in 'ci/install-dependencies.sh'

[SZEDER Gábor]

Ever since we started using Travis CI, we specified the list of
packages to install in '.travis.yml' via the APT addon.  While running
our builds on Travis CI's container-based infrastructure we didn't
have another choice, because that environment didn't support 'sudo',
and thus we didn't have permission to install packages ourselves.  With
the switch to the VM-based infrastructure in the previous patch we do
get a working 'sudo', so we can install packages by running 'sudo
apt-get -y install ...' as well.

Let's make use of this and install necessary packages in
'ci/install-dependencies.sh', so all the dependencies (i.e. both
packages and "non-packages" (P4 and Git-LFS)) are handled in the same
file.  Install gcc-8 only in the 'linux-gcc' build job; so far it has
been unnecessarily installed in the 'linux-clang' build job as well.
Print the versions of P4 and Git-LFS conditionally, i.e. only when
they have been installed; with this change even the static analysis
and documentation build jobs start using 'ci/install-dependencies.sh'
to install packages, and neither of these two build jobs depend on and
thus install those.

This change will presumably be beneficial for the upcoming Azure
Pipelines integration [1]: preliminary versions of that patch series
run a couple of 'apt-get' commands to install the necessary packages
before running 'ci/install-dependencies.sh', but with this patch it
will be sufficient to run only 'ci/install-dependencies.sh'.

This patch should go on top of 'ss/travis-ci-force-vm-mode'.

I'm not sure about the last paragraph, because:

  - It talks about presumed benefits for a currently still
    work-in-progress patch series of an other contributor, and I'm not
    really sure that that's a good thing.  Perhaps I should have
    rather put it below the '---'.

  - I'm confused about the name of this Azure thing.  The cover letter
    mentions "Azure Pipelines", the file is called
    'azure-pipelines.yml', but the relevant patch I link to talks
    about "Azure DevOps" in the commit message.

Anyway, keep that last paragraph or drop it as you see fit.

OK, so far we learned that this is now _doable_; but not enough to
decide if this is a good thing to do or not.  Let's read on to find
out.

So we used to have two waysto prepare the test environment; non
packaged software were done via install-dependencies.sh, but
packaged ones weren't.  Unifying them so that the script installs
both would be a good change to simplify the procedure.  

Is that how this sentence argues for this change?

Is this "unneeded gcc-8 was installed" something we can fix only
because we now stopped doing the installation via apt addon?  Or we
could have fixed it while we were on apt addon but we didn't bother,
and this patch fixes it "while at it"---primarily because the shell
script is far more flexible to work with than travis.yml matrix and
this kind of customization is far easier to do?

So the main point of this change is to have less knowledge to
prepare the target configuration in the .travis.yml file and keep
them all in ci/install-dependencies.sh, which hopefully is more
reusable than .travis.yml in a non Travis environment?

If that is the case, it makes sense to me.

Yeah, this paragraph is just a bit of background about how the current
situation came to be and what recent change made the switch possible.

Now that you mention it: no.  It would have been possible to install
gcc-8 only in the 'linux-gcc' build job even via the apt addon, namely
by removing the two Linux build jobs from the implicit build matrix
and adding them as two independent build jobs in the 'matrix.include'
section of '.travis.yml'.  The drawback is that all the extra packages
used in both build jobs would have to be duplicated.

Basically yes (though I think it's not about not bothering; I don't
know about others, but it just occured to me that it would have been
doable, however, even if it occured to me earlier, because of the
duplicated list of common packages I wouldn't have done it).

Doing it in good old shell is indeed easier and the common packages
are then only listed once.

Oh, "more reusable" indeed, that's a more eloquent way to put it.

Originally I meant its own axis, but perhaps the moon.

I see, you had fun talking about a revolution [*1*]...

I am much in favor of this patch, as it indeed will simplify the
integration into Azure Pipelines.

As to the DevOps vs Pipelines thing: DevOps is the umbrella, it consists
of much more than just the automated builds (Pipelines), it also has
Boards, Packages, etc, but I don't think we will ever use that in the Git
project, as our workflow is based out of a mailing list.

Ciao,
Dscho
