Our complicated heuristics for handling multiple packages of the same
name comes back to bite us. In the multilib case, we can have packages
of the same NEVR, but different arch, sitting in the same tree.
Previously, even if the arch was different, we would still mark it as an
upgrade or downgrade. But that complicates things in the case of
multiple packages of the same name in the same tree.
We greatly simplify things here by making the diff algorithm dumber. We
now only consider a package as "modified" (i.e. upgraded/downgraded) if
it has the same NA (but different EVR). This makes handling multilib
cases natural and seems worth it overall vs trying to handle the odd
e.g. noarch <--> archful pkg transitions that could happen.

This patch introduces a new `AutomaticUpdatePolicy` configuration. This
was a long time coming for rpm-ostree, given that its update model makes
it extremely apt for such a feature.
The config supports a `check` mode, which should be very useful to
Atomic Workstation users, as well as a `reboot` mode, which could be
used in its present form in simple single node Atomic Host situations.
There is still a lot of work to be done, including integrating
advisories, and supporting a `deploy` mode. This feature hopefully will
be leveraged as well by higher-level projects like GNOME Software and
Cockpit.

In #875 AKA b46fc35901 we
added support for the `releasever` option in treefiles. I am
pretty sure it worked at the time...but I didn't add tests.
Either it never worked or some refactoring broke it. The whole chain of
`GKeyFile` → `GVariant` is so confusing. Anyways fix it by copying the string.
Now let's use it by default in the compose tests, and while we're here bump
those to F27.
I'm doing this patch now as I was playing with doing a compose from
the `/usr/share/rpm-ostree/treefile.json` and wanted to use the stock
`.repo` files.

It obviously shouldn't block the ability to install, and anyways

This reverts commit 1ef259ed76.
Basically, for historical POSIX compatibility, `errexit` doesn't work at
all inside functions called from an if-statement/boolean context. This
is something I had already learned (and forgotten) when hacking on PAPR.
There are ways around this, but it's just not worth the added complex
shell goop for what it gives us.

Basically we're choosing the libdnf behavior of omitting `Epoch: 0` which IMO is
the sane thing to do even though in *theory* they're different RPMs but
who would ever ship both without incrementing release/etc?

`grep` supports checking multiple fixed strings separated by newlines,
but it's mostly just easier to pass them as separate arguments, so let's
support that. This is now at parity with the similar
`assert_file_has_content`.
Will upstream this to ostree as well once reviewed.

This is the first step towards unifying how we introspect packages from
a specific commit. We currently do this in three ways: libdnf, librpm,
and now `rpmostree.rpmdb.pkglist`. I'd like to get to a point where we
only have `rpmostree.rpmdb.pkglist` and libdnf, the latter only when
more complex queries are required.
This patch teaches the `db diff` command to make use of the new db diff
API so that it can work even on metadata-only commits. This is relevant
for use cases mentioned in #558.
I didn't get rid of the `rpmhdrs_diff` functions right now because of
the `--changelogs` option: libdnf currently does not expose this, so we
fall back to the previous API in that case. OTOH, I wonder how much it's
actually used in the wild; maybe we could just nix it?

`test -n` would always be true. Also while I have the patient open

We originally needed the pkgcache to be a separate repo due to ostree's
overzealous pruning policies. The idea was to maintain multiple commits
in each pkg branch for different SELinux policies. In practice, there's
not much use in maintaining old copies and it's just easier to always
relabel on the fly. So then, the need for a separate repo completely
melts away.
This helps simplify the mental model a bit and allows us to avoid subtle
issues like #1047. Note however that the core is still capable of
handling split repos for the `--ex-unified-core` compose use case. Once
that and the jigdo work are a bit more settled, we can have a clearer
picture of how to simplify the core further.
The tricky bit is migrating the cache. When deploying, we check if a
pkgcache repo exists and migrate its refs if so. We then leave behind a
symlink to the system repo to remain compatible with older rpm-ostrees.
Closes: #1055

I've been lazy about actually using using rsync instead of scp when
copying new RPMs over to the VM. We do this here. Also make
`vm_send_test_repo` take a mode argument that allows callers to
completely skip the sending of the repo file itself. This will be needed
for the `makecache` test, in which we *don't* want the repo to be local.
It looks cleaner anyway for the gpgcheck use case as well.

Prep for implementing `rpm-ostree cancel`, but this works with the way we handle
`Ctrl-C` interactively on a client as well. Being able to cancel a script
execution is quite nice; some of them are expensive, and having one loop forever
has been known to happen.

There's a lot of paths in the core related to SELinux policy changes and
relabeling packages. We currently have no test coverage for them. We add
support in the test libraries here to build such packages.
We also add a test that checks both that we correctly relabel RPMs when
the policy changes and that we handle layered packages that install
SELinux packages properly.

We have some unit-style tests that run `ex container`, but
they aren't "real"; they don't use scripts for example. Let's
add tests for this similar to `tests/compose`.
We use a 26 base, but the target repos need to be 27
to pick up the fix for: https://bugzilla.redhat.com/show_bug.cgi?id=1478172
Add some bits to share infra between `tests/compose` and `tests/ex-container`;
basically handling the rpmmd repos. I tweaked things to be more streamlined
there between the `.papr.yml` and the test script.
Right now this is just one test for `bash`, but lays some of the infrastructure
for doing more. One thing that we need to do to improve more here is to better
cache RPMs, a bit like the compose tests do.

Rather than just letting the scriptlets inherit the daemon's

It turns out there's a much smaller limit than PATH_MAX for Unix
sockets. On Linux, it's 108 characters. It took me some time to figure

File triggers are a post-RHEL7 thing; more information at
http://rpm.org/user_doc/file_triggers.html
There are two notable users I've been testing this with;
`glib2` and `vagrant`. The `vagrant` one is more immediately urgent,
since it makes `vagrant-libvirt` work, which I currently rely on
for my workstation dev.
I've tested things successfully with `vagrant`, and I did verify that we run the
`glib2` ones when doing `rpm-ostree ex container`.
Long term, more transaction file triggers are likely to live in
"base" packages like `glib2`. We don't implement those yet, but
extending this to do that shouldn't be too hard.
There was *significant* what I'd call reverse engineering of the
implementation in librpm. The file triggers code there is spread out
and abstracted in a few different places in the code. I found
trying to understand what header values were involved to be quite
tricky.
There are some corner cases like multiple patterns that I *think*
this does correctly, but could use more validation. The main
question I had was - is it required that the patterns for e.g.
`%transfiletriggerin` and `%transfiletriggerun` be identical?

This is required for glibc-all-langpacks at least:
https://bugzilla.redhat.com/show_bug.cgi?id=1367585
Otherwise, its usage is...extraordinarily rare. In fact looking at a snapshot of
`rpm-specs-20170518.tar.xz` from Fedora, the only other use is in
`postfix.spec`, and it appears bogus (the value is already expanded at build
time).
But the glibc case is special, as the value of `install_langs` is indeed
potentially dynamic per system.

Add experimental support for replacing packages from the base layer with
local RPMs. This is useful for example, to cherry pick a fixed package,
or to roll back to a previous package version. Like with pkg removals,
only files in /usr are actually replaced.
This patch also contains a few usability improvements as well, e.g.
showing the full NEVRA of removed packages rather than just their names,
and support for resetting overrides using either the pkgname or NEVRA.

Seen in the wild with `vagrant`'s use of `%post -p /usr/bin/ruby`. This was a
very easy fix, and actually makes the code a little bit nicer, as we no longer
need to explicitly make the script executable, since we now pass it as
`argv[1]`, the same way librpm does. That in turn would make it possible to fix
the TODO and use `bwrap --file`, but that can come later.

Nuke all the previous goop that was used to create RPMs at `make check`
time and transition all the tests to use the new `build_rpm` function.
It definitely feels cleaner to use. It's also really nice to have the
spec live in the same file as the test that uses it.

Having to prepare RPMs in advance separately from the tests that use
them severely limits our ability to test various cases and to iterate
quickly when creating tests.
Add a new `build_rpm` function which can basically build the RPM on the
fly and update the yum repo afterwards. It makes it trivial to test
things like package updates:
build_rpm foo 1.0 1
<stuff>
build_rpm foo 1.0 2
<stuff>
The RPMs are all created inside the temporary test directory and thus
cleaned up on exit.
I'm doing this in a separate commit because it's the most important diff
of the transition and might be easy to lose in the larger diff where we
move all the tests to make use of this.

This was a kind of last-minute bug introduced when I tweaked the
checkout to use `.` to avoid a `mkdir()` for files. But there were
multiple bugs with that; for files that are in subdirectories of `/etc`
we obviously need to get the right subdir and not use `/etc`.
Second, we need to handle the case where we're adding new subdirectories.
This change fixes `rpm-ostree install firewalld + rpm-ostree ex livefs`.

There are a few different use cases here. First, for layering new packages,
there's no good reason for us to force a reboot. Second, we want some support
for cherry-picking security updates and allowing admins to restart services. Finally,
at some point we should offer support for entirely replacing the running tree
if that's what the user wants.
Until now we've been very conservative, but there's a spectrum here. In
particular, this patch changes things so we push a rollback before we start
doing anything live. I think in practice, many use cases would be totally fine
with doing most changes live, and falling back to the rollback if something went
wrong.
This initial code drop *only* supports live layering of new packages. However,
a lot of the base infrastructure is laid for future work.
For now, this will be classified as an experimental feature, hence `ex livefs`.

This was argued on list a while ago: http://lists.rpm.org/pipermail/rpm-ecosystem/2016-August/000391.html
Basically, every use of `%pretrans` is a workaround for some in-place
upgrade problem. But we never do inplace updates, we always assemble
a new tree. Hence, there is no point for us to ever execute these.
Let's stop erroring out on them. If there does turn out to be some problem with
a particular package (e.g. the `openjdk-copy-configs` or whatever), we would
likely end up needing to fix that package's `%post`, not start executing its
`%pretrans`.

I originally thought there was a bug here, but missed we were skipping

1. Don't require an ssh-config
In the case of redhat-ci, the VMs are already fully configured for the
system (injected in the hosts file, host key accepted, etc...). So
there's no need to have an ssh-config there. In general, it should be
acceptable to run the vmcheck suite against a resolvable host without
having to create an ssh-config for it.
2. Make the host name configurable
Rather than hardcoding "vmcheck" as the hostname, allow overridding it
by specifying a VM env var directly. We also prepare the various scripts
to make use of the $VM variable whenever host-specific dirs/files are
created so that parallel runs won't step on each other.

While reading a recent conversation about GPG checking at treecompose
time, I had a sudden thought - were we actually doing verification
client side? Turned out, we aren't. That happens as part of
`dnf_transaction_commit()` which we don't use.
That function verifies every package at one go, but for us I think it's better
to do it before "importing". We shouldn't have untrusted bits that we've
unpacked (they might have suid binaries, for one thing).
This is an embarassing problem, but it's worth emphasizing that everyone should
be retrieving repodata at a minimum over TLS, which sets a baseline. On RHEL, we
already do pinned TLS, and there are discussions about extending that elsewhere.

We don't want to expose the host's `/tmp` since that means scripts could
