This creates a archive-z2 repo, pull-locals it to bare-user and then
again back to archive-z2 making sure things fsck along the way.
Then it checks out all repos and makes sure each one reproduces
the same result.
Unfortunately we can't install this as a real test because
it doesn't work in the test-runner because tmpfs doesn't support
user xattrs.

This just does whatever test-basic.sh does, but on a bare-user
repo.
This works standalone, but unfortunately it breaks in
gnome-desktop-testing-runner as /tmp doesn't support
xattrs, so it is not installed atm.

Use the pattern:
$PRETTY_NAME [$COMMIT_VERSION] (ostree[:$OSNAME][:$DEPLOYMENT_INDEX])
$OSNAME is only shown if there are multiple values.
$COMMIT_VERSION refers to the version tag in the commit's metadata.
$DEPLOYMENT_INDEX is only shown if no $COMMIT_VERSION is available.

For Anaconda, we have an ugly bootstrapping problem where we need to
add the remote to the repository's config, then do a pull+deploy, then
remove and re-add the config, because /etc/ostree/remotes.d doesn't
exist yet in the target system.

In this approach, we drop a /etc/grub.d/15_ostree file which is a
hybrid of shell/C that picks up bits from the GRUB2 library (e.g. the
block device script generation), and then calls into libostree's
GRUB2 code which knows about the BLS entries.
This is admittedly ugly. There exists another approach for GRUB2 to
learn the BLS specification. However, the spec has a few issues:
https://www.redhat.com/archives/anaconda-devel-list/2014-July/msg00002.html
This approach also gives a bit more control to the admin via the
naming of the 15_ostree symlink; they can easily disable it:
Or reorder the ostree entries ahead of 10_linux:
Also, this approach doesn't require patches for grub2, which is an
issue with the pressure to backport (rpm-)OSTree to EL7.
Some operating systems may come with external tools for subscription
management that drive access to the content. In that case, the origin
file may not be useful (for example, it could refer to an installer
ISO).
This patch will allow OS installers to inject that state, with a
useful error message, directing the system administrator to an
external tool.

Recursive over ostree and all subcommands, and check that --help
is supported, properly outputs to standard out, and exits
with a 0 exit status. Check that for commands with subcommands,
they produce the help output to standard error when run with no arguments.

Previously, in the case where a parent directory of a modified config
file was removed, we would throw an exception. This happens when
switching from a tree that has some software (e.g. firewalld), to one
that does not.
While it's nice to have this warning that your config file probably no
longer applies, there's no need to make it so...fatal.
It's particularly problematic that the only easy workaround is to
remove the config files from your current tree - which breaks
rollback.
The solution then is for for us to take ownership of the parent
directories too into the new /etc. Admins can clean up these files
afterwards at any time.

While looking to fix a different bug here, I found the current
state of things where we had a mix of fd-relative API versus not
frustrating.
Change the code around to consistently use *at, and also add some more
tests.
For Fedora and potentially other distributions which use globally
distributed mirrors, metalink is a popular solution to redirect
clients to a dynamic set of mirrors.
In order to make metalink work though, it needs *one* file which can
be checksummed. (Well, potentially we could explode all refs into the
metalink.xml, but that would be a lot more invasive, and a bit weird
as we'd end up checksumming the checksum file).
This commit adds a new command:
$ ostree summary -u
To regenerate the summary file. Can only be run by one process at a
time.
After that's done, the metalink can be generated based on it, and the
client fetch code will parse and load it.
https://bugzilla.gnome.org/show_bug.cgi?id=729585
Changes the pull API to allow pulling only a single directory instead
of the whole deployment. This option is utilized by the check-diff
option in rpm-ostree.
Add a new state directory to hold <checksum>.commitpartial files, so
we know that we've only downloaded partial state.
If we deployed a new tree inside an existing OS, inheriting kernel
args, we need to use append() instead of replace() to avoid collapsing
multiply specified kernel arguments like console=/dev/foo
console=/dev/bar.

The user might "ostree ls /usr/bin/bash/blah", which previously would
segfault.
A somewhat related future enhancement here would be for "ostree ls" to
follow symbolic links.

This patch adds a function that will parse a partial checksum when
resolving a refspec. If the inputted refspec matches a truncated
existing checksum, it will return that checksum to be parsed. If
multiple truncated checksums match the partial refspec, it is not
unique and will return false. This addition is inspired by the same
functionality in Docker, which allows a user to reference a specific
commit without typing the entire checksum.
partial checksums: Add function to abstract comparison
This modifies the list_objects and list_objects_at functions
to take an additional argument for the string that a commit starts
with. If this string arg is not null, it will only list commit
objects beginning with that string. This allows for a new function
ostree_repo_list_commit_objects_starting_with to pass a partial string
and return a list of all matching commits. This improves on the
previous strategy of listing refs because it will list all commit objects,
even ones in past history. This update also includes bugfixes on
error handling and string comparison, and changes the output structure
of resolve_partial_checksum. The new strcuture will no longer return FALSE
without error. Also, the hashtable foreach now uses iter. Also
includes modified test file
There's several use cases for calling into ostree itself to do
mirroring, instead of using bare rsync. For example, it's a bit more
efficient as it doesn't require syncing the objects/ directory.

If fetching GPG-signed commits over plain HTTP, a MitM attacker can
fill up the drive of targets by simply returning an enormous stream
for the commit object.
Related to this, an attacker can also cause OSTree to perform large
memory allocations by returning enormous GVariants in the metadata.
This helps close that attack by limiting all metadata objects to 10
MiB, so the initial fetch will be truncated.
But now the attack is only slightly more difficult as the attacker
will have to return a correctly formed commit object, then return a
large stream of < 10 MiB dirmeta/dirtree objects.

I was getting a weird hang in the installed tests with the shell as a
zombie process, not reaped by the parent, which was just stuck in
select() on the output pipes. The thing is we don't actually want to
capture stdout/stderr, we just want to inherit.
GSystem.Subprocess makes that possible, so let's just use it now that
it's a proper installed library.
We don't want to allow MITM attackers to intercept upgrade requests
and provide clients with older OS versions vulnerable to security
flaws.
Only "ostree admin upgrade" gets this behavior for now - whether we
want to do it for "ostree admin switch" is another question.
These GPG tests were failing for me on EL7 - it appears to be because
we had only one directory for both private and public keys, and we
were giving that to ostree for verification, which passed them onto
gpgv.
In EL7 beta at least, gpgv now barfs if it finds a private key where
it is just expecting to find public keys.
Fix this by splitting out the public trusted directory from the
private key directory. Except now for signing, we still need the
public key there, so symlink it. Whee!
This has a very basic level of functionality (deltas can be generated,
and applied offline). There is only some stubbed out pull code to
fetch them via HTTP.
But, better to commit this now and improve it from a known starting
point, rather than have it languish in a branch.
This test had some nondeterminism because we chose a random
object to corrupt, but because there were multiple commits, it
was possible that we chose an object that was not being pulled.
Fix this by writing some custom GJS code to find an explicitly random
object that exists in a given ref, an change a random byte offset.
This adds a lot more randomness to the testing too.
The "ordered hash" code was really just for kernel arguments. And it
turns out it needs to be a multihash (for e.g. multiple console=
arguments).
So turn the OstreeOrderedHash into OstreeKernelArgs, and move the bits
to split key=value and such into there.
Now we're not making this public API yet - the public OstreeSysroot
just takes char **kargs. To facilitate code reuse between ostree/ and
libostree/, make it a noinst libtool library. It'll be duplicated in
the binary and library, but that's OK for now. We can investigate
making OstreeKernelArgs public later.

The test-admin-deploy-1 was copied into -uboot at some point. But
really they should be testing exactly the same thing, except for
the bootloader backend.
Unify these tests by extracting a common test core.
