The instructions for doing a release were outdated. Take the opportunity
to just move it to a dedicated markdown file and breaking it out to make
it easier to follow.
This is one step short of using a release checklist like some of the
other CoreOS projects do. This is a good base to eventually do that if
we want.
Going to update rpm-ostree for RHEL 8.3, we did a huge bump
in libdnf which now defaults to enabling zchunk in its build
system. We added the infrastructure before to detect things,
so propagate that to libdnf.
The current `rpm-ostree-2020.1-1.fc31.x86_64` in Fedora
was [built with a truly ancient libostree](https://kojipkgs.fedoraproject.org//packages/rpm-ostree/2020.1/1.fc31/data/logs/x86_64/root.log)
because Fedora's build system is weird and only adds packages
released after "gold" into the buildroot via an override
that times out.
This actively breaks things because rpm-ostree isn't
detecting the read-only sysroot.
Let's bump our hard requirement.
We don't *actually* use this ourself, but librepo does, and libdnf gets confused
if librepo doesn't support it. This is the case in RHEL8 currently.
Basically what breaks is trying to use the Fedora EPEL repo (has zchunk metadata)
on RHEL CoreOS. And we have a test in kola that does this today.
I think we're in a good position now for FCOS enablement, and there are
a bunch of fixes we should get out, such as the zstd one.

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`.

rdgo is choking on this right now because, even though we added
`/usr/share/bash-completion` to the list of dirs to check in the spec
file[1], we don't have `bash-completion` installed in the buildroot, so
the `completionsdir` pkgconfig var isn't defined and we end up
defaulting to `/etc/bash_completion.d`.
el7's bash (not that it matters much now after #1785) is indeed new
enough to know that location. See also
https://github.com/ostreedev/ostree/pull/1083.

Teach rpm-ostree to interpret rebases where the remote component is a
path to a local repo, e.g.:
rpm-ostree rebase /mnt/ostree/repo:my/target/ref
Essentially, the local remote in this case is considered "ephemeral".
It's kind of the equivalent of, on traditional systems:
dnf install --repofrompath repo,/path/to/repodata ...
The use case for this is in OpenShift v4, in which upgrades are done
from containers containing the OSTree commit. There, we want to point
RPM-OSTree directly at the repo in the mounted container and rebase to
the checksum.
For now, the option is marked experimental. One major reason for this is
that the way we pass the repo differs on RHEL7 vs other platforms. (See
comment block in `rpmostree-dbus-helpers.c` for details).

Let's make use of the GitHub release feature to make it more prominent
on the "Releases" tab, but more importantly so that we can attach
vendored tarballs for downstreams. E.g. this will allow us to have a
correct `Source0` field in the Fedora spec file.

Today I was trying to use gdb and noticed my libdnf build didn't
have debuginfo. Now, I thought that's what `-DCMAKE_BUILD_TYPE=RelWithDebugInfo`
was doing but...I have no idea right now where I got that.
I looked at RPM builds, and the way this works is it exports CXXFLAGS.
Now for our C code, our defaults actually come from Autoconf. Let's
do the beautiful hack of telling Autoconf we're going to use C++ so
it sets `CXXFLAGS` for us.

The problem is building bindgen as part of our single run
locks serde to way old versions, and I want to use newer versions.
Since Fedora will now again ship a `cbindgen` package, let's
also support using it if we find it, saving ourselves
the cost of building it.
For distros that don't ship it (e.g. CentOS) for CI purposes
we build it. For downstream builds that are offline, rather
than vendor the cbindgen sources like we do with our main Rust,
let's just vendor the `rpmostree-rust.h` file as was suggested
in https://bugzilla.redhat.com/show_bug.cgi?id=1608670

This removes the logic around supporting opting out of the staging
feature. We don't want to support multiple configurations here, and at
this point, staging should be considered stable.

It seems like `4.14.2-rc1` orders later than `4.14.2`, which is causing
issues in f28 builds.
Also print the version of librpm at configure time.

This teaches the client to fetch packages from URLs directly so that one
doesn't have to `curl` first and then install. Supported anywhere
package filenames are allowed (notably: `install` and
`override replace`).
One neat things about this is that we download the file into an
`O_TMPFILE` and then pass on ownership of that fd directly to the
daemon. So at no point are the packages actually laying visible on the
system. (Assuming the filesystem supports `O_TMPFILE` that is).
This adds direct linking to libcurl and openssl, two libraries which we
were already pulling in indirectly.

When building in `debug` mode, `RUST_DEBUG` was still turned off because
`rust_debug_release` was set to `yes`, not `debug`.
Fix this by tweaking how `--enable-rust-debug` works: when it's *not*
provided, we default to the `$CFLAGS` detection logic. Otherwise, it
overrides it.

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.

We've put a lot of work into staged deployments, it's time
to pull the trigger and turn them on by default. This is
a key step for enabling `stage` mode automatic updates by
default in e.g. Fedora CoreOS/Silverblue.
We add a new `--disable-staged` build-time option to flip
things back.

Newer librpm defaults to doing a full payload checksum, which we can't
do at this point (writing the db) because we imported the RPMs into
ostree commits, saving just the header in metadata - we don't have the
exact original content to provide again.

This entirely drops out Sphinx as well as python-devel from our
builds, makes builds faster, and silences a lot of warnings too.

Skip building man pages and HTML docs for our embedded libdnf to speed
up builds.
This bump also pulls in a fix to ensure we never try to install src

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.

Let's modernize and start supporting YAML treefiles. I'll dare make the
sweeping generalization that most people would prefer reading and
writing YAML over JSON.
This takes bits from coreos-assembler[1] that know how to serialize a
YAML file and spit it back out as a JSON and makes it into a shared lib
that we can link against. We could use this eventually for JSON inputs
as well to force a validation check before composing.
If we go this route, we could then turn on `--enable-rust` in FAHC for
now and drop the duplicate code in coreos-assembler.
