We need this for https://cxx.rs
While we're here:
- Add some more comments/links
- Since the Rust bits are now at the toplevel, we can explicitly
invoke `cargo`
- And since we can do that, use the `+` syntax to specify the
toolchain explicitly
We lost this during the transition from PAPR to CoreOS CI. We don't have
a lot of new tests there since new unit tests tend to be in Rust, though
we should still run what we do have.
Repurpose the `rust` branch to more generically run all unit tests
and not just the Rust ones. It still also checks that compilation
against the MSRV works fine.
The default `_NPROCESSORS_ONLN` heuristic we have isn't cgroups aware.
So it thinks it has e.g. 40 CPUs when running in a k8s pod. This can
then blow through our allocated resource limits.
Declare some modest amount of RAM and CPU resources and override `make`
parallelism.
This matches what ostree does in
https://github.com/ostreedev/ostree/pull/2151.
This is needed by the compose tests. This is part of cosa already, which
is why CI isn't hitting this, but we want to support users not
developing on top of the cosa buildroot container that can just run
`ci/installdeps.sh`.
Jenkins does its own `git merge` when testing PRs. Doing a naive
`git diff ${merge_commit}^..${merge_commit}` won't work right because
it might perform a diff across multiple commits.
What we want to do here is to just skip trivial merge commits or
otherwise error out on them if they're non-trivial (since it likely
means that one did conflict resolution manually instead of rebasing,
which we should encourage).
The `origin/master..$HEAD` range will correctly still contain all the
parents of any merge commit which is not yet in `origin/master`.
We haven't been consistent about doing this; I personally
think rustfmt is a big aggressive with the line wrapping
but eh, consistency is more important.
And heh so I tried to `git push --set-upstream cgwalters` and
that failed because there was an already extant `rustfmt`
branch from a while ago...looking at that code it got lost
in the CI refactoring - we're not running `build-check.sh`
at the moment.
Move the rustfmt bits into `codestyle.sh` which is closer
to where it should be anyways.
FAHC is super out of date now. The way to have access to newer packages
is via the continuous tag, which is still manual for now, but at least
targets the right Fedora release.
Doing builddep once based on the baked config and then once more from
the spec file can cause issues sometimes. For example, right now the
latest rpm-ostree release uses libmodulemd1, but we want to rebase to
libmodulemd (2.0). And `dnf` will get confused trying to move from one
to the other.
Really, we don't need to builddep from the last release at all, so just
drop that and rely only on the spec file.
Adapt `pkg_install_builddeps` to allow no args to mean only installing
the basic buildroot stuff like `dnf builddep` and `@buildsys-build`.
We need `cargo` in our `PATH` and we already do the `PATH=...` dance in
`ci/msrv.sh`. This only worked before because we were inadvertedly
re-installing cargo when calling `ci/build.sh`, which was fixed in the
previous commit.
We've already manually installed dependencies higher up. This saves us
some time, but also we don't want the script to e.g. re-install cargo.
(This also works as a short term hack we need to adapt to libdnf moving
to `libmodulemd-2.0` due to `ci/installdeps.sh` not being entirely
idempotent).
We want to run the unit tests after a build, so do that.
Furthermore, this actually installs the binaries, which
means if we do it as part of a `Dockerfile` build, we
can use that image for further testing.
This is an experiment in using Jenkins pipelines for our CI. See similar
initiatives in coreos-assembler[1] and fedora-coreos-config[2].
For now, this only does the following testing:
- checks commit for unintended submodule bumps
- checks the minimum Rust version
- builds RPMs
- builds FCOS (with the new RPMs both for executing the build
itself, as well as included in the built OS)
There are dummy placeholders for where we'd actually run the vmcheck
and the compose testsuites. Let's address those trickier parts as
follow-ups.

So this is a somewhat significant change, but I'd like to try having the
canonical spec file upstream. A few reasons for this:
1. We integrate tightly with the distros we're destined for, and so
we're in a pretty good position for knowing how the software should
be packaged.
2. We can atomically change packaging along with the rest of the code.
This has important ramifications, including that it'll be easier to
integrate with continuous build services like Packit, but releases
will also be less fraught with last-minute packaging fixes.
3. I'm playing with Jenkins pipelines and there I'd like to make RPMs
the "artifact" that gets moved down the pipeline into later stages
(e.g. `cosa build`). We could even eventually make it an actual
external artifact so that anyone can easily download RPMs from any
random PR for testing. (And in fact, with a thin yumrepo layer on
top, it could be used to replace Packit/rdgo entirely).
Not that this approach doesn't have issues as well (e.g. on the dist-git
side, we'll need some minimal tooling to merge in the changelog), though
I think it's worth trying out.

This is a bit of a hack, but does the trick now. Eventually, we'll need
to either bump rdgo to f30, or set up continuous builds some other way
(e.g. Packit or Jenkins pipelines).

Jenkins' `checkout scm` gives us the exact commit that we're testing.
Allow passing that to the submodule commit message checker so it doesn't
use `HEAD` (which is likely GitHub's merge commit).

This is an exact copy of https://github.com/ostreedev/ostree/pull/1906
for now. From that commit message:
I'd like to add OpenShift's prow to this repository. Let's start
by adding a Dockerfile - it doesn't really do anything besides build.
However...I've lately been thinking about e.g. shipping the ostree tests
as an image, and then e.g. we could test FCOS by running that container
(which would orchestrate the host's ostree).
Anyways, not doing that right now but this is a start.
Since we have to pull it anyways to do a build, let's use it
as a buildroot. This should fix CI which broke because we were
doing a f29 build but cosa is f30, and libostree differed.
Drop the use of Ansible everywhere. In the few cases where we really
Python, just spawn a container instead.
This is required to be able to hack on Fedora CoreOS.
Closes: #1850
Approved by: jlebon
This bumps the requirement on the controlling host to Python 3 only.
It also bumps the requirement on the target host to Python 3 as well
since FCOS doesn't ship Python 2 right now.
Though we'll need to eventually drop all Python usage anyway, but at
least let's get tests passing on FCOS first. (See related previous
patch).
Closes: #1828

This brings us back in sync with the latest libdnf git master. This
required a bunch of work both on the libdnf and rpm-ostree side to get
working. See e.g.
https://github.com/rpm-software-management/libdnf/issues/645.
A few things to adapt to:
- soname bump to `libdnf.so.2`
- `DnfAdvisory` is no longer a `GObject` (annoyingly it's not replaced
by something we can keep a ref on, so this requires some hacks to
steal from the `GPtrArray` -- could enhance libdnf for this later)
- disable SWDB history writing
- use new reldep public API
- update for latest `hy_subject_get_best_selector()` API
This now unlocks the possibility to add support for modules. (One can
see hints of this in the diff by the fact that `libdnf` links to
`libmodulemd1`.)

Right now there's an issue in Fedora with `g-ir-scanner` picking up
`-fstack-clash-protection` from the `sysconfig` Python module and
passing it to `clang`, which doesn't understand this flag yet.
Just work around this by (1) not even building GIR bindings for our
bundled libdnf since there's no need, and (2) overridding the compiler
used by `g-ir-scanner` so it's always `gcc`.

- Use `IFS=` so that we don't drop leading whitespace when reading in,
which can be used to specify multiple baseurls on multiple lines.
- Use `-r` as good practice so we don't try to interpret anything.
- Use `echo "$line"` so that we don't drop leading whitespace when
writing out.
Closes: #1787

This is a bit of a selfish request, though I also really like
`ci/build.sh` for hacking in a throwaway environment. This patch allows
one to rerun `ci/build.sh` without erroring out on `testuser` already
existing.
Closes: #1621
Approved by: cgwalters
Move specific package mentions from the `.papr.yml` file to
`ci/installdeps.sh`. I find the latter script super useful for
bootstrapping a pet container for rpm-ostree development and this helps
with that.

As something that manages your base operating system, we care
about reliability, predictability, as well as performance and
low-level access to native operating system facilities. The
C programming language is great for the latter two, but fails
at providing a truly memory-safe environment. Rust is fairly
unique in providing a language that doesn't carry a runtime,
so we can gradually "oxidize" and convert our C code without
imposing additional overhead. It's also got a lot of modern
design niceties, like not having a null pointer.
Let's pull the trigger here and hard require Rust. It's the
programming language I personally want to be primarily writing in for
years to come.
This is also in line with a recent trend of reducing our
experimental/optional matrix.
Closes: #1509

Probably at some point libdnf will drop py2 support, but the
main reason I'm doing this is avoids a python2 dependency
for rpm-ostree for distributions that don't want that.
Note of course rpm-ostree itself doesn't use python, libdnf does.
And only for the python bindings, which we don't use either. So
this is mostly just to DTRT automatically for the libdnf bits; down
the line we could probably add a patch to make the python fully
conditional.
