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 is an initial drop of support for:
`rpm-ostree rebase rojig://fahc:fedora-atomic-host`. We also
then support `rpm-ostree upgrade` from that.
There's a lot that could be improved here; the test coverage is relatively
minimal. A blocking issue there is having a realistic jigdo setup, and that's
going to require changing how we do testing. For now, this means that if we want
to e.g. change the format we'll have to temporarily disable this test, get the
format change in, update FAHC, then re-enable the test.

I'm working on supporting `override replace ./kernel-*.rpm`:
https://github.com/projectatomic/rpm-ostree/issues/946
But after battling the "installonly" logic in libdnf, I was confused why we
still had the files in `/usr/lib/modules`. It turned out to be because we only
remove files in `/usr`, but the code didn't handle UsrMove compat links.
There are a variety of approaches to fix this. Obviously a lot
of things get nicer in jigdo mode as we do UsrMove canonicalization
on import, and we could change this code to walk the imported pkg
ostree ref.
Another approach would be to walk the initial symlink, and check whether or not
it's the same as `/usr` (i.e. let the kernel do it).
For now though, what I chose to do was to scan the rootfs and find the UsrMove
compat links (i.e. we avoid hardcoding them again here). This is
fewer syscalls than the above and works well in practice.
Closes: #1226

This is what a lot of other tools do. It can get very verbose, with a
potentially huge amount of output if things are trickling in. This way
we're at least more friendly to someone running `cmd: rpm-ostree upgrade`
via Ansible or equivalent.
The slight hack here is that we *do* output `100%` on non-ttys to ensure we
print the result of the task.

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.

I spent some time trying to figure out why on CentOS my changes to
`/etc/rpm-ostreed.conf` didn't seem to have any effect. It turns out
that for some reason I didn't spend too much time looking into, the
autoconf in CentOS defaults to `${prefix}/etc` when `--prefix` is given.
This is also why I was under the erroneous assumption that D-Bus config
files were in `/usr/etc` in CentOS. This patch fixes that as well.

Let's standardize on the default config file when running tests. We copy
the original out of the way and install the default one so tests can do

This is essentially a revert of #1190. I initially changed from storing
the epoch, version, and release separately to together to avoid endian
issues with epoch. This works around that instead by just encoding it as
a string.
As is done in our custom NEVRA printer (which before #1190 we used
here), we make sure that epochs of "0" are not printed as part of the
`nevra` or `evr` members.
Closes: #1198

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

This fixes a large swath of compatibility issues, for the same reasons as
overlayfs makes a lot of things Just Work. The ugly part of course is
doing hidden copyups inside the filesystem.
We've gone quite a long time with the "pure rofiles" mode, and have made changes
to various bits of userspace to be compatible with it. But what finally made me
give up on that is glibc's locale-archive; there's a patch for it that
is stalled, but even if it was applied we would still need to work with
older glibc.
This issue comes to the fore in unified core 🌐 mode, as without this

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?
Closes: #1162
Approved by: cgwalters
The new `rpmdb.pkglist` metadata is a cheap way of retrieving the set of
packages in a commit. I'd like to make use of it as much as possible vs.
checking out the rpmdb and setting up a DnfSack.
Of course, in the case of layered commits, it doesn't matter *as* much,
because a layered commit being present in the repo should mean that a
deployment is currently using it, and we should learn to reuse the rpmdb
checkout of that deployment. Though keeping it consistent across both
server and client commits makes implementing `OstreeDeployment`-agnostic
things like `db diff` more efficient too. I also plan to use this in the
upcoming auto-update code.

This rolls up several libglnx changes: https://github.com/GNOME/libglnx/pull/101
Now of course things are trickier here because we have an internal
abstraction over directly emitting to a console versus sending the
result over DBus. Further complicating things is that some things
call into libdnf and thus *require* use of `DnfState` which does
not give us the "n items" information, versus other parts which
we implement and can do what we want.
Even *further* complicating things is that we have to take care around non-CLI
callers like Cockpit; so I didn't try to pass the "n items" over DBus, rather
just reimplemented the "insert into text" that libglnx is doing.
Anyways overall this looks better IMO for all cases.

This function is now basically reimplementing all of the intelligence
we have in libostree today. It wouldn't have worked before we
fixed https://github.com/ostreedev/ostree/issues/1165 but now
that's done, conceptually we just need to call
`ostree_repo_commit_modifier_set_sepolicy()`. However, I had
to drop the "number of files changed" since currently the libostree
API doesn't support that.
Also, in order to detect the case that content changes at all (so
we still have some useful information in the journal), implement
a "content hash" check.

Right now the fact that one can only cancel via `Ctrl-C` of an existing client
process is rather frustrating if for example one's ssh connection to a machine
drops. Now, upon reconnecting, one can easily `rpm-ostree cancel` a hung update

(which is safe of course, unless livefs is involved).

Note this PR requires [bubblewrap 0.2.0](https://github.com/projectatomic/bubblewrap/releases/tag/v0.2.0).
Change our bwrap invocations drop truly dangerous capabilities like
`cap_sys_admin` and `cap_sys_module` just like Docker does today. Because of the
popularity of Docker, we can be pretty sure that most RPM scripts should have
adapted to this (although a problematic area here is that traditional librpm
doesn't actually error out if scripts fail).
There are two reasons to do this:
- We want "offline" updates by default; updates shouldn't affect the
running system. If we prepare the new root in the background, a
%post shouldn't restart a service for example. We already "handle"
this by making `systemctl` a symlink to `/bin/true`, but this approach
also shuts off `%post`s that do e.g. `insmod`.

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

It took me way, way, way too long to debug that my dev container somehow missing
`ostree-grub2` caused the script to fail early, but we'd still continue trying

leading to test suite failures.
Also add the chmod hammer at the top so we can delete even if we fail after
doing an rsync.

will replace the value and change hi=hello into hi=new.

I also took a step further here and inject an `original-origin` metadata
key, though we aren't actually using that yet. The problem I'm trying
to solve there is that repeated `make vmoverlay` starts chaining things up,
but that gets very confusing. I think we should always have `vmoverlay` unwind
back to the base ref. (Or at least do that by default)

To complement the new `--cache-only` option, add a `--download-only`
option. This does exactly what it says: we download the ostree, download
and import packages, but don't actually commit & deploy. This can be
used to effectively prime a follow-up `--cache-only` operation that can
be done during a more convenient/safer maintenance window.
I debated naming the two options `--pull-only` and `--deploy-only` like
the ostree equivalents. Though "pull" felt like the wrong word given
that it's associated more with ostree pulling but rpm-ostree also
downloads & imports RPMs. As for `--deploy-only` vs `--cache-only`, it
seems like `--cache-only` is a more accurate description of the
functionality (i.e. rather than describing an action, it describes a
mode). I also considered `--no-download` to make the synergy with
`--download-only` more obvious. Maybe that's better? Naming is hard...

As Colin mentioned in #1035, the new `--cache-only` implemented only the
rpmmd half of the story. Here we complete that story by also ensuring
that when in cache-only mode, we don't download new ostree data nor new
packages. We try to complete the requested operation with what we have.
To do this, we add support for the same `SYNTHETIC` pull that was added
in ostree[1] so that we don't actually pull, but still perform timestamp
checking.
On the pkgcache side, we disable all remote repos and instead insert all
our cached RPMs into the `DnfSack`. Care is taken to still perform
SHA256 verification for local pkg installs/replacements.

I've been lazy about actually using using rsync instead of scp when

Commands like `upgrade` and `deploy` need to know if a new deployment
was actually laid down so that it may print a pkg diff if so. This is
implemented by listening for changes to the DefaultDeployment D-Bus
property. D-Bus emits a signal when the deployment variant changes
value.
However, in #595, with the introduction of `pending-*` related keys, the
deployment variant no longer represents data solely tied to that
specific deployment. In this case, because `deploy` operations currently
set the ref to the resolved checksum, it can happen that deploying the
same base commit when the current refspec *isn't* pointing to that base
commit will result in the `pending-*` keys dropping out and a default
deployment change notification going out.
In this patch, we strengthen how we determine whether a new deployment
was laid down by actually looking at the deployment id, rather than just
assuming that a change to the property implies a new deployment.

At one point `rpm-ostree install libvirt` dragged in libguestfs which in turn
brought in `syslinux-extlinux-nonlinux` which has files in `/boot/extlinux`,
which we rejected. (That dependency chain appears to have been fixed currently)
For the general case, this is just a partial fix in that we haven't nailed down
the semantics of how updates for `/boot` work. But in this particular case,
we'll just break libguestfs' `extlinux` verb, which I'm OK with.
Another case is `fwupdate-efi` - we require manual intervention to copy the
data into `/boot` after installing the package.
This is also preparation for [unified core](https://github.com/projectatomic/rpm-ostree/issues/729)

This closes a longstanding bug - since package layering first
landed, we only checked for newer RPMs if the base tree changed.
In some scenarios like RHELAH, this doesn't matter much by default
since they move at the same cadence. Except if you use EPEL for example.
In Fedora, today the FAH releases are async of the rpm-md repos, and
there's also COPR which can update more than once a day even.
We should check for both update sources. Luckily we'd already introduced logic
for this in the treecompose case (checksumming the depsolved package sack). We

The new API to find pending and rollback deployments do so relative to

time a user uses "rpm-ostree rollback", it would (as expected) move the

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?

Follow-up tweak to #894. Make the client smarter so we only register
when we know we can. We could be more sophisticated here and e.g.
introduce the concept of "read-only" clients in the daemon to only allow
access to non-mutating methods, though let's delay that discussion at
least until the daemon learns to auto-exit.

This is a followup to https://github.com/projectatomic/rpm-ostree/pull/888
but more comprehensive; in the layering case, the sanitycheck runs
after all the `%posttrans` scripts, so we'll get a consistent error message
for the `rm -rf /` test.
We also do the sanitycheck for the "pure ostree" case, as well as cases
where we didn't actually layer packages (including `ex override remove` as
well as simply regenerating an initrd).
There's obviously a lot more we could do in a sanitycheck; as I say in the
comment it's tempting to consider trying to boot systemd (in a fully volatile
config), but for now let's do this. In the end of course the admin has rollback
too.

I was thinking today about our script handling, and I realized
an excellent way to showcase the advancement rpm-ostree makes
over traditional package managers is the fact that we survive a
`%post` script that does `rm -rf /`!
See e.g. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=858521
It's been this way ever since we first implemented package layering;
the fact that we construct a new root and use bubblewrap to sandbox
makes us very resilient to this type of thing.
But, let's add a test case for this to be sure we preserve this behavior; for
example, if in the future we for some reason we decide to leak some host state
into the scripts.

This is required for glibc-all-langpacks at least:

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.

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.

The property of removal overrides dropping out if the package was
removed from the base layer felt a bit too magical and hacky. We really
should remember that wish and re-apply it if the pkg comes back. This is
similar to package layering: requests can become inactive (seems like a
better word than "dormant") if the package is already part of the base
layer, but they don't really go away.
This patch reworks the logic so that removal overrides work the same
way. In the status output, we now have both "RemovedBasePackages" and
"InactiveBaseRemovals" (which is only printed in verbose mode),
similarly to how we have "LayeredPackages" and "InactiveRequests". And
similarly, we also print out in the upgrader during a transaction all
the inactive base removals.
Another cool thing is that we now allow any pattern to be specified at
the CLI. E.g. `ex override remove /usr/bin/strace` will resolve to
strace.

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.

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`.

Conceptually: we're going to move rpm-ostree and ostree at the same
cadence most of the time; for both releases *and* for git master.
The problem so far has been the latter part. Reusing FAHC
for the build gets us half of the problem.
The other trick I realized we can do - just pull ostree out from the build
container. This avoids fetching it from the internet, and makes my workflow for
hacking on both nicer - I just `sudo make install` in my build container for
ostree.
It's tempting to make the whole thing symmetric and require `sudo make install`
for rpm-ostree and not do the insttree thing but...perhaps after.

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 sometimes talk about using `ostree admin undeploy`, but that
doesn't know about the pkgcache, and hence space there leaks
until the next rpm-ostree operation.
Just for this, we need to expose a cleanup command (and API). But
we also need to support cleaning:
- repomd
- downloads (repo/tmp)
So let's start implementing that.

Until now, we always used the booted deployment, and would
garbage collect the "pending" deployment. This is the
way OSTree was designed, but I think for rpm-ostree given
how mutable we are on the client side, there's a much stronger
argument for being more stateful too.
This is a relatively simple code change to split the "merge deployment"
concept into two. There's now the "config merge deployment" and the
"origin merge deployment".
Basically, `rpm-ostree install foo; rpm-ostree install bar` will
now install both `foo` and `bar`. But we will still use the booted
deployment for `/etc`.
Down the line, I think I'd like to drive into OSTree the concept of
a "staged" deployment, that has the hardlink checkout done, but doesn't
have the config merge.
But we don't need to change the OSTree core for this yet; we can
do it here in rpm-ostree, and this relatively simple code change
fixes many issues at once.
For example, `rpm-ostree upgrade && rpm-ostree install foo` now
does what you expect as well.
Obviously, we want to enable doing multiple things in *one* transaction,
and we're not far away, but I think this is also the right thing to do now.
I'm relatively confident it won't break anyone's workflow, as what
we did before wasn't generally that useful. However, people will
need to learn to `ostree admin undeploy 0` if they *don't* want
this behavior. (We need to have `rpm-ostree cleanup`).

I'm watching https://github.com/rpm-software-management/libdnf/pull/199 and I
really don't like it. We already have a place to put out-of-rpmdb metadata,
which is in the ostree commit for imported packages. No need to involve a
relational database for this (and further, one that would need to learn about
multiple ostrees).
We're not yet *using* this information in the UI, but we could; imagine
changing the `status` `Packages:` to show packages-per-repo or so. We
could also expose an `rpm-ostree pkg-info foo`.
But for now, let's just start recording this.

One thing that's very confusing about OSTree is there are two layers -
deployments and the refs/commits. If one does an `rpm-ostree upgrade`, but then
e.g. `ostree admin undeploy 0`, you still have the new revision in the repo.
We don't do a good job of displaying this state, or helping people clean
it up.
Down the line, I also want to better support something like `rpm-ostree pull` to
cache updates explicitly *without* deploying.
This commit just adds a bit of information to the status display. We might want
to have better formatting, but I think this an OK start.

The actual problem I am trying to fix with this is fallout from the
introduction of `/usr/libexec/rpm-ostreed`, which required a SELinux
policy change. Specifically for CentOS, the base policy is rev'd
slowly.
My hope was that by merging the daemon code back into `/usr/bin/rpm-ostree`
which is labeled `install_exec_t`, starting via systemd would do
the right thing. It turns out that doesn't happen.
Now later, I'm picking this patch back up because I want to do multprocessing in
the daemon (and in the core), and it makes sense to share code between them,
because multiprocessing will need to go through a re-exec path.
Another benefit is we avoid duplicated text (libglnx, internal helpers) between
the two binaries.

When we checked out the base tree for package layering, we would create
the directory in which ostree did the checkout. This meant however that
ostree wouldn't apply xattrs on the root directory itself. This would
cause the directory to be mislabeled (as system_conf_t instead of
root_t), which in turn cause SELinux violations on reboot when systemd
tried to make the root mount shared.
This patch fixes this by first settling on a permanent directory in
which to do checkouts -- really, we'll never have multiple package
layering operations going on at the same time. Once we know that we have
a reserved path, we can safely let ostree create it for us with the
proper xattrs.

Currently we push for a model where the initramfs is
generated (in non-hostonly mode), and merely replicated.
However, to support a few unfortunate corner cases like dm-multipath which wants
to inject a config file into the initramfs, we need to support regenerating it
client side too.
Down the line, we'll need this to support overriding the kernel too.
This changes things in the core to add the concept of an "empty"
`RpmOstreeContext`. I initially tried skipping it, but that was too much
duplication. We still want all of the core ostree-related logic that lives in
that code too.
The treespec bits barfed if the spec didn't have a `tree/packages` key. It was
simplest to change that to allow it - and because that was the only case where
we errored out in parsing, I dropped the error handling.
There was another place in the upgrader that now needed to be fixed to handle
transitioning from just regenerating initramfs to not.

My development environment is now using "pet" docker containers.
I use VMs for testing things that require that (like rpm-ostree).
This patch builds on work from @jlebon in
https://github.com/projectatomic/rpm-ostree/pull/509
to rework `vmcheck` such that it can work on any `ssh-config`. By
default we expect this to be Vagrant.
However, I go a lot farther and delete the `vmbuild` code that was
trying to do builds in a container on the target VM. I think this is
still worth pursuing at some point, but for now I think it's
reasonable to assume that the rpm-ostree developer audience uses Linux
as their host workstation and hence has containers.

level things like rpm-ostree, there's a strong push to make the VM
disposable and not a pet)
