Downloads and prints a remote summary file and any signatures in an
easy-to-read format, or alternatively with the --raw option, prints
the summary GVariant data directly.

Adds an entry to the origin file to force the OstreeSysrootUpgrader to
pull and deploy the given checksum.
[origin]
override-commit=CHECKSUM
If the option is not given, any such entry is explicitly removed from
the origin file to ensure we upgrade to the latest available commit.
New public function works like ostree_sysroot_cleanup() EXCEPT FOR
pruning the repository.
Under the hood, add _ostree_sysroot_piecemeal_cleanup() which takes
flags to better control what files are cleaned up. Both public cleanup
functions are now wrappers for _ostree_sysroot_piecemeal_cleanup() with
different flags.
The new API permits to query a remote repository summary file and
retrieve the list of available refs.

It allows to specify whether GPG verification for the summary file is
enabled for a specific repository.

Works like "ostree refs" but fetches refs from a remote repo.
This depends on the remote repo having a summary file, but any repo
being served over HTTP *ought* to have one.
Imports one or more GPG keys from a source stream or from the user's
personal keyring into a remote-specific keyring. The keys to import
can optionally be restricted by a list of key IDs.
The imported keys are used to conduct GPG verification when pulling
from the given remote.
The blocking locking API wasn't sufficient for use in the rpm-ostree
daemon; it really wants to know if the lock is held, then continue to
do other things (like service DBus requests), and get notification
when the lock is available.
We also add an async variant that can be called if the lock is not
available.
Implement a higher level "loop until lock is available" method in the
`ostree admin` commandline.
I use the trivial httpd server locally. Each time I restart the
server, I end up modifying manually the config file for other repos so
to point to the correct port. In this way I can just re-use the same
port.

An OSTree user noticed that `ostree fsck` would produce `missing
object` errors in the case of interrupted pulls.
It's possible to do e.g. `ostree pull --subpath=/usr/share/rpm ...`,
which gets you just that portion of the commit. The use case for this
was being able to see what changes would appear in an update before
actually downloading all of it.
(I think this would be better covered by static deltas, but those
aren't final yet, and `--subpath` predates it)
Further, `.commitpartial` is used as a successor to the `transaction`
symlink for more precise knowledge in the case where a pull was
interrupted that we needed to resume scanning.
So it makes sense for `ostree fsck` to be aware of it.
If a system administrator happens to type `ostree admin upgrade`
multiple times, currently that will lead to a potentially corrupted
system.
I originally attempted to do locking *internally* in `libostree`, but
that didn't work out because currently a number of the commands
perform multi-step operations that all need to be serialized. All of
the current code in `ostree admin deploy` is an example.
Therefore, allow callers to perform locking, as most of the higher
level logic is presently implemented there.
At some point, we can revisit having internal locking, but it will be
difficult. A more likely approach would be similar to Java's approach
with concurrency on iterators - a "fail fast" method.
This way external programs like rpm-ostree can do fd-relative
operations on the deployment directories, like inspecting the RPM
database.

rpm-ostree currently uses ostree_repo_checkout_tree(), which as a side
effect will use the uncompressed objects cache by default. This is
rather annoying if you're using rpm-ostree on a server-side
repository, because if you then rsync the repo, you'll be syncing out
the uncompressed objects unless you exclude them.
We added the ability to disable the uncompressed cache in the
repository config to fix this, but it's better to allow application
control over this. The uncompressed cache will in some future version
become opt in as well.
This new API further:
- Drops the `GFile` usage in favor of `openat` APIs
- Improves ergonomics by avoiding callers having to query the source
`GFileInfo` (and carry around a copy of `OSTREE_GIO_FAST_QUERYINFO`)
- Has a more extensible options structure
Per the comment, I rather crudely have the `ostree checkout` builtin
call both APIs to ensure some testing coverage.
However, I'd like to in the future have easier-to-set-up testing code
that calls `libtest.sh` to set up dummy data.
Wrappers a referenced gpgme_verify_result_t so detailed verify results
can be examined independently of executing a verify operation.
_ostree_gpg_verifier_check_signature() now returns this object instead
of a single valid/invalid boolean, but the idea is for OstreeRepo to also
return this object for commit signature verification so it can be utilized
at the CLI layer (and possibly by other programs).
Convenience feature to avoid having to pass --repo options repeatedly.
Before falling back to the default system repository path, check for a
repository path defined by the OSTREE_REPO environment variable.
See projectatomic/rpm-ostree#42 for rationale. There are two high
level use cases:
- If the OS comes unconfigured, this is a way to point it at a repo of your choice.
- To switch between repositories while keeping the same branch easily.
