0975a42125 compose: Add --download-only-rpms
Prep for making `--unified-core` the only path.  It turns
out our compose testsuite has a lot of hardcoded ideas about
how the two paths work.  The rojig tests in particular need
cached RPMs, so we can't just rely on caching the pkgcache repo.

Add a `--download-only-rpms` that always returns RPMs, and doesn't
import into the pkgcache repo.

02b25c616d libpriv/kargs: Strengthen and simplify new kargs APIs
Note this patch only touches the *new* APIs that aren't part of
libostree.

Now that we can use `g_ptr_array_find_with_equal_func`, we can drop our
custom `_ostree_ptr_array_find`.

Also strengthen our handling of values everywhere to handle the `NULL`
case and properly support `KEYWORD` args. I ended up getting rid of
`_ostree_kernel_arg_query_status` in the process since it made that
assumption a lot and overall added more complexity than necessary.

b324ee4807 app/status: Always print pending deployment diff
Right now we only print a diff of the pending deployment if we have a
cached update (which only happens if user just did an `upgrade`
operation). But really, we can just always print this for the pending
deployment regardless of whether there's a cached update calculated.

This is prep for changing chained operations to only show the diff
between the previous pending deployment to the new pending deployment.
With this patch, the full diff from booted to pending will always be
available through `status` (and `db diff` too though it's not as nice).

ad1451fac2 Rebase to latest libdnf
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`.)

44110377c6 vmcheck/test-rojig-client.sh: Don't check full rojig NEVRA
Let's make this test work across major version rebases of the FAHC
treecompose job by not hardcoding a specific `%{dist}` here. It's strong
enough to check that the `deploy` operation has the expected previous

I'd like to add a new `boot-location: modules`.  In prep

a newer rpm-ostree and that they expect people to be able to use as an
upgrade target from a libostree that predates that.

2be532c9e9 rust/treefile: Add basearch key
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`).

677c083f24 libpriv: Rebuild policy during postprocessing
It's possible for some postprocessing scripts to affect the final
SELinux policy. This is the case for the new `/etc/default/useradd` edit
we now do (#1726), but it could've been the case beforehand too with
user scripts modifying e.g. booleans (though ideally all these
modifications would be part of RPMs).

Do a final `semodule -nB` during postprocessing so that the final policy
we commit is "up to date". Otherwise, users may only see changes take
effect if they layer packages that trigger a rebuild.

The motivation for this is specifically for `/etc/default/useradd`.
There is magic in `selinux-policy` that parses the file and generates
templated rules from the value of `HOME`.

58a79056a8 libpriv/scripts: Add /run/ostree-booted for scriptlets
RPM-OSTree has been pretty good so far at consuming the exact same RPMs
used for traditional OSes without modifications. This is important,
because shielding RPMs from the OSTree abstraction means we remain
compatible with a large portion of the ecosystem.

However, there are some apps that definitely require rethinking their
approach. The example right now is akmods, which has a patch proposed to
build kmods at `%post` time on OSTree systems instead of from the
daemon.[1]

In such situations, scriptlets need something to key off of for the
OSTree-specific approach. The `/run/ostree-booted` file is the de facto
API to determine if we're running on an OSTree system or not. This patch
simply extends this API so that scriptlets can naturally make use of
them.

7cceb35219 app/rebase: Support local repo remotes
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).

a20d10e3d5 libpriv/util: Add date field in auto-versioning
This adds an optional date field to the prefix
passed by automatic_version_prefix. An example of specifying
the field is as follows:

10.<date:%Y>

And the fields progress like:

10.2018.0
10.2018.1
10.2018.2
10.2019.0

The date format creates a new "current date" string using
valid date directives passed into g_date_time_format().

If there is a problem reading the given date format,
an error is given and the next version is returned as NULL.

If no <date:...> tag is detected in the auto version prefix,
the same behavior as before (appending .1 and incrementing) occurs.

This may be helpful to avoid writing glue code to auto-update
the version if a date string in the commit version is desired.
Otherwise, --add-metadata-string=version= is an alternative for
complete customization.

56e6ddb8e5 compose: Change /etc/default/useradd to use HOME=/var/home
For a long time I've resisted encoding "policy" into rpm-ostree
as much as possible.  Doing so makes it more distribution specific
for example.  That said, for `/var/home` there argument for doing
this in rpm-ostree is that we already make that symlink in our
hardcoded rootfs.  So we might as well do the other fixups for it.

is "How serious and relevant are these advisories to me? How soon should
I reboot?". For the packages that I'm most familiar with, e.g. `kernel`
and `git-core`, I usually look up the advisory and check why it was
marked as a security update, mentioned CVEs, and how those affect me.

The updateinfo metadata includes a wealth of information that could be
useful here. In Fedora, CVEs treated by the security response team
result in RHBZs, which end up attached to the advisories and thus make
it into that metadata.

This patch tries to reduce friction in answering some of those questions
above by checking for those CVEs and printing a short description in the
output of `status -a`. Example:

140704c105 daemon/transaction-types: Fix dnf cache override
Minor regression from #1587. There were places that were still doing
`dnf_context_set_cache_age()` manually, but those calls didn't exactly
have the intended effect since the core now handled caching itself.

The actual result was that the metadata was still being updated, but not
during the `dnf_repo_check` pass that the core does, but rather the
`Importing rpm-md` pass it does right after. So then, we were
incorrectly printing `(cached)` even though we'd update it afterwards.

Switch to the new way of doing things.

1dee43319c Use indicatif for progress
This turned out to be messier than I thought, because of two primary
factors; the biggest mess here of course is the indirection
through the DBus API.

The other problem is that previously we passed the string to render
each time, and with current indicatif that'd trigger a rerender.
Since (usually) don't change the "prefix string", rework the API.

Change the "percent/n_items" bits to use autocleanups as well, and
to take the prefix string as an initial argument.

Since the state expands to multiple components, also change the
API to use the `0-initialized` pattern rather than trying to
return an aggregate.

We also gain a "sub message" which we use to display e.g.
package names as we're doing checkouts.  Note this ends up
at the end, since otherwise everything else jumps around.

50b255a8a9 Move varsubst code into Rust, use it in treefile parsing
External tools often want to parse the ref; for example coreos-assembler
currently does so.  Let's ensure `${basearch}` is expanded with
`--print-only` so they can parse that JSON to get the expanded version
reliably.

Implementation note: this is the first Rust code which exposes a
"GLib-like" C API, notably with GHashTable, so we're making more use
of the glib-rs bindings.

88ffdc0ae2 Add compose rojig command
This currently requires a `--i-know-this-is-experimental` flag;
I know it'd be a bit more consistent to have it under `ex`, but
what feels weird about that is *most* of the `ex` commands people
use are client side.  This is where we want it to ultimately end
up.

We've landed a lot of prep patches, but I know there's still
a notable amount of code duplication with `compose tree`.  What's
left is about ~700 lines but it's mostly not hard/complex code
anymore.

In the future, I'd like to extract more of the compose code
to a `rust/src/compose.rs` or so, but I think this is sustainable
fow now.

My high level goal is to get this into coreos-assembler and stand
up a Silverblue build that uses it.

940fc1364a compose: Check that add-files are compatible after parsing
While serde gives us type checking, it of course doesn't understand
semantics beyond that. One example is checking the compatibility of
`add-files` entries with the OSTree model. This is something we can do
upfront early on to avoid surprises for users.

Also tweak the docs to reflect this new check.

fca01e70b5 Lower initial SELinux policy load from compose to core
Add a `selinux` verb to treespec, and bind it from treefile.  If
set, use it in the core to load an initial policy before import,
if we didn't already set a policy.

In practice right now this is only used from the compose path
since the SysrootUpgrader uses the policy from the merge deployment.

Unset the policy if rojig mode is enabled.

Now, non-SELinux use cases are required to set `selinux: false`
in the treespec. For `ex container` I just set it in our example
specs.  Probably that should forcibly disable it in the
treespec but eh, it's experimental.

The other case I can think of is client-side layering; before
we would create a policy using the target root, but it
wasn't a *hard* requirement, i.e. we didn't error out if
`policy_get_name() == NULL`.  Let's preserve that semantic by
hooking off of whether `_new_system()` was used.

Prep for sharing code with `compose rojig`.

676519e5a5 status: Print systemd or ostree staged failure msg
Try to tease out a bit more info from the journal by looking at the
systemd message when the service transitions to the dead state or even
looking at the OSTree output itself.

Example outputs:

```
[root@f28-ros ~]# rpm-ostree status
State: idle
Warning: failed to finalize previous deployment
         error: opendir(ostree/deploy/fedora-atomic/deploy/887c95887a3047a60372016a0d84536530755b60df3cca33c819f7606e220adf.0): No such file or directory

$ rpm-ostree status
State: idle
Warning: failed to finalize previous deployment
         check `journalctl -b -1 -u ostree-finalize-staged.service`

(Though open to tweaking it).

I also played with directly invoking `journalctl` for the user, but that
can get really spammy with e.g. `os-prober` output and such.

I wrote this in Rust using journal API wrappers because I also plan to
implement the `history` command in Rust and will also enhance that new
`journal` module there for that.

b3f6f25637 core,scripts: When no cachedir+unified-core, disable rofiles-fuse
This is prep for running inside (unprivileged) Kube containers
as they exist today: https://github.com/projectatomic/rpm-ostree/issues/1329

Sadly FUSE today uses a suid binary that ends up wanting CAP_SYS_ADMIN.
I think there's some work on FUSE-in-containers but I'm not sure of
the current status.

What rofiles-fuse here is doing here is protecting is the hardlinked
repo imports.  But if `--cachedir` isn't specified, that repository
gets thrown away anyways.  So there's no real value to using FUSE
here.

Also since nothing is cached, disable the devino cache.

We also make use of --force-copy-zerosized that just landed
in libostree: https://github.com/ostreedev/ostree/pull/1752

Down the line ideally we gain the capability to detect if either
unprivileged overlayfs/FUSE are available.  Then if `--cachedir`
is specified we can make things work.
