This is just generally useful, though I'd like to make use specifically
of the new `metadata.generated` key in FCOS to drive versioning:
https://github.com/coreos/fedora-coreos-releng-automation/pull/50
All this does is put the immutable bit on the target directory.
The intention is to replace this bit to start:
8b205bfbb9/src/create_disk.sh (L229)
However, the real goal here is to add code in this file
to handle redeploying the rootfs for Fedora CoreOS which
combines OSTree+Ignition:
https://github.com/coreos/fedora-coreos-tracker/issues/94
Basically doing this in proper Rust is going to be a lot
nicer than shell script in dracut modules. Among other
details, coreutils `mv` doesn't seem to do the right thing
for SELinux labels when policy isn't loaded.
This is the rpm-ostree equivalent of `dnf history`. As opposed to the
history of the refspec (i.e. `ostree log`), this shows the history of
the system, i.e. the refspecs the host deployed, checksums, versions,
layered packages, etc... The amount of details remembered is similar to
what shows up in `status`.
There's definitely some further enhancements possible (e.g. printing
package diffs, displaying rollbacks), though this seems in good enough
shape as a first cut.

We have contacted all contributors to the code in `rust/` and
that code is now all relicensed under the "standard Rust license"
of `Apache 2.0 OR MIT`.
[Due to an accident](https://github.com/projectatomic/rpm-ostree/issues/1890),
some GPLv2+ code was imported in the C side, and we're unlikely to
easily change that now. Make this more official by adding the GPLv2.
I'd like to go through the C code and add SPDX and possibly investigate
relicensing some of the GPLv2+ code to LGPLv2+ but, not right now.
For a bit more about Rust and SPDX, see [this issue](https://github.com/rust-lang/cargo/issues/2039).

I have multiple outstanding PRs that use it and they conflict on
this, so let's just upstream it now.
It helps avoid some use of `unsafe` talking to libc directly.
I wanted to use this in another project, and I don't think
we're the only ones. I extracted the code, added better docs
and tests, and published to crates.io:
https://crates.io/crates/openat-ext
* treefile: Rework test helper
Have each test clearly hold its tempdir; this way we can have a simple
helper function rather than a struct with an unreferenced parameter.
Also use `utils::write_file`.
Prep for further test work.
* treefile: Add a basic test for includes
Prep for adding an arch include test.
* treefile: Support `arch-include`
A long time ago we added architecture-specific package lists
via e.g. `packages-ppc64le`. Much more recently we added
support for having the `include` key be a list - multiple includes.
By combining these two and supporting architecture-conditional includes,
we've effectively added architecture-conditionals to *all* keys.
Notably we want this for Fedora CoreOS today which is using
`remove-from-packages` on `grub2-tools` which isn't present on
s390x.
* ci: Bump cosa build timeout
Looks like another OpenStack perf regression.
I'm working on having Silverblue inherit from Fedora CoreOS. But
conceptually it also inherits from (parts of) Workstation.
It is just easier if we support multiple inheritance, then I don't
need to think too hard about how to make it a single inheritance chain.

We had essentially the same test in the `lockfile` and `treefile`
modules. Just dedupe those and move it to `utils`.
Closes: #1867

When manually writing lockfile overrides (see previous commit), it's
sometimes easier to not have to specify the SHA256 of the package. For
example, in FCOS, all packages on development and production streams
will be sourced uniquely from coreos-pool, so there's no question of
where the package will come from. It's of course also easier in the
context of local development.
Another motivation for this though is a subtle interaction between
Fedora infra and the way we'd like to implement lockfile management: we
want the override process to be PR-based, with a privileged bot in the
backend tagging new overrides into the pool as necessary on merge.
However, packages built in Koji are initially unsigned, and so we can't
actually *know* what the SHA256 of the package will be until it's signed
and tagged into the pool by the bot.
Closes: #1867

Teach `rpm-ostree compose tree` to accept multiple `--ex-lockfile`
arguments. In this case, later lockfiles can override the NEVRA for
packages specified in previous lockfiles.
This will be used in the FCOS pipeline, where we want to be able to have
a shared "base lockfile" and then stream-specific "override lockfiles".
I contemplated making this an `include: ...` key instead similar to the
manifests, but I'm not sure that paradigm fits as nicely for lockfiles.
Making it separate switches instead also makes it trivial to implement
in cosa.
(And of course, this is all still prefixed with `--ex` which means we
are at liberty of changing this interface later on after gaining some
experience with it).
Closes: #1867
Approved by: cgwalters
There are two reasons for this:
1. I'd like to add overrides semantics to lockfiles, and keying by the
package name only makes this much easier.
2. I'd like to make the digest optional, and keeping it as a tuple makes
this awkward.
A map seems natural too since it makes it more clear that we don't
expect multiple specifications for the same package name.
Another tiny advantage is that it's easier to process with e.g. `jq`.

I wanted to modify the lockfile specification, but then remembered that
it currently lives in two places right now: once on the Rust side where
it's deserialized, and once more on the C side where it's serialized.
If we could write the lockfile from the Rust side, then we wouldn't have
to deal with the `GVariantBuild` and `json-glib` goop, and instead
we could consistently use serde against the same struct for both
serialization and deserialization.
But there isn't an easy way to do this given that the state to be
serialized is intrinsically linked to libdnf.
So this patch takes the next step in our oxidation process by adding a
minimal `libdnf_sys` module which allows us to call `libdnf` functions
from Rust. This is not the prettiest code I've written, and there's
definitely some polishing that could be done. But I think overall it's a
move in the right general direction: as we oxidize more things, we'll at
some point *have* to integrate more tightly with the C side in a
bidirectional way, instead of the "one-way" approach we've been using so
far.
For this patch specifically, in exchange we get a unique source of truth
for the lockfile spec, just like the treefile, and we drop a lot of C
code in the process.
Closes: #1867
Approved by: cgwalters
Let's just make it really obvious that this is the function that reads
the lockfile.
Prep for also having a symmetric `ror_lockfile_write` function.

Move hashing to the Rust side so that we can easily hash over the final
set of inputs after parsing. This means that we now hash over all the
externals, like `add-files` references, any `postprocess-script` script,
and `passwd` and `group` files.
The original motivation for this was that hashing over a reserialized
version of the treefile was not deterministic now that treefiles include
hash tables (i.e. `add-commit-metadata`). So I initially included each
individual treefile as part of the hash.
I realized afterwards that just switching to `BTreeMap` fixes this, so
we can keep hashing only the final flattened reserialized treefile so we
ignore comments and whitespace too. But since I already wrote the patch,
and it fixes a real issue today... here we are.
One notable change though is that we now hash the treefile in non-pretty
mode to increase the chances that the serialized form remains stable.
Ironically, this change is likely to cause a no-op commit once it gets
to pipelines which iterate quickly. All for the greater good though.
Closes: #1865
Approved by: cgwalters
Add support for a new `add-commit-metadata` key in the treefile so that
we can directly specify commit metadata we want to inject from there.
This will be useful in Fedora CoreOS, where we'll have separate
treefiles for each streams, each with stream-specific metadata values
required.
Closes: #1865
Approved by: cgwalters
Besides allowing ${releasever}, only do the substitution as the final
pass after merging the treefiles for all the keys (currently ${basearch}
and ${releasever}) instead of doing it per parse. This way we have the
expected semantics where one could do:
```
include: "fedora-coreos.yaml"
releasever: "42"
```
and have that releasever used.

Using glib_json to parse the lockfile yields some oddities like

The use case for `ostree-layers` is to support injecting non-RPM
content in a more flexible way than can be done with `add-files`,
and also without dropping all the way to split composes.
This starts with support on the `compose tree` side but down the
line I'd like to make it more convenient to do *client* side too.
For `ostree-override-layers` this is mainly a development thing
for tools like coreos-assembler. Rather than building an RPM
we just `make install DESTDIR` then commit and add to
`ostree-override-layers`.

Now that we no longer support el7, let's peg our minimum `rustc` version

now.
And drop use of deprecated `trim_left_matches()` (it was deprecated in
1.33.0, which is currently used in the other testsuites that pull
`rustc` from the Fedora repos; we might want to eventually just use the
`RUST_MIN_VERSION` in all the testsuites to not get caught in the middle
like this again).

And this (for now at least) completes the epic journey of the

it avoids duplicating the content as the locations may have
different SELinux labels.

I'd like to add a new `boot-location: modules`. In prep
for that, let's remove the legacy `both` which drops into
`/boot`.
The libostree support for handling `/usr/lib/ostree-boot` has

deploy: Ensure that we can deploy using only /usr/lib/ostree-boot

I think we assume now that no one is now making *new* treecomposes and needs
a newer rpm-ostree and that they expect people to be able to use as an
upgrade target from a libostree that predates that.

The recent dep bump caused rand to jump to v0.6.5, which pulled in
`fuchsia-cprng`. Sadly, the cargo version we're frozen on chokes on it
because its manifest makes use of the `edition` keyword, which wasn't
stabilized yet.
Let's just freeze the problematic crate for now. We should be able to
bump our Rust toolchain soon-ish.
(Note this commit also does some other minor crate bumps as a result of
regenerating the lockfile to prune away `fuchsia-cprng`.)

Add a `basearch` key to the manifest. This can be used at compose time
to assert the architecture the compose is running on. Though my
motivation is for the common case where it gets omitted from the input
manifest and gets automatically added by rpm-ostree into
`/usr/share/rpm-ostree/treefile.json` for introspection on the client.
(The crucial part here is that the treefile created by rpm-ostree
remains deserializable into a `TreeComposeConfig`).

This uses the `Context` feature of the failure crate to make error
messages more useful when we fail to open a file. The difference with
`map_err` is that one can still obtain the underlying error from the
context if need be. Though surprisingly, the normal `Display` for a
`Context` doesn't include the original error, so we essentially have to
do a prefix here (see [1]).
Before:
```
error: Failed to load YAML treefile: No such file or directory (os error 2)

After:
```
