When working with collections it can be useful to see remote refs rather
than just local and mirrored ones. This commit changes the "ostree refs
-c" output to include remote refs, and includes remote refs with
collection IDs in summary file generation as well. The former behavior
is consistent with how "ostree refs" works, and the latter behavior is
useful in facilitating P2P updates even when mirrors haven't been
configured.
To accomplish this, OstreeRepoListRefsExtFlags was extended with an
EXCLUDE_REMOTES flag. This was done rather than an INCLUDE_REMOTES flag
so that existing calls to ostree_repo_list_refs_ext continue to have the
same behavior. This flag was added to ostree_repo_list_collection_refs
(which is an experimental API break).
Also, add unit tests for the "refs -c" and summary file behavior, and
update relevant tests.

Things like https://sourceware.org/libabigail/manual/abidiff.html
look interesting but in a brief look I couldn't work out
how to conveniently use them for quick ABI sanity checking without
doing a diff from a previous build (which we could do but would be
more involved).
This way will at least catch struct ABI breaks on x86_64 which
I think we'd be most likely to do accidentally when trying
to use one of the previous unused values.
I found the hole values via gdb's `pahole` command.

This parallels ostree_repo_remote_list_refs(), but returns a map of
OstreeCollectionRef → checksum, and includes refs from collection IDs
other than the remote repository’s main collection ID.
Use this in OstreeRepoFinderConfig to ensure that refs are matched
against even if they’re stored in the repository summary file’s
collection map, rather than its main ref map. This fixes false negatives
when searching for refs in some situations.

There are multiple use cases where we'd like to alias refs.
First, having a "stable" alias which gets swapped across major
versions: https://pagure.io/atomic-wg/issue/228
Another case is when a ref is obsoleted;
<https://pagure.io/atomic-wg/issue/303>
This second one could be done with endoflife rebase, but I think
this case is better on the server side, as we might later change
our minds and do actual releases there.
I initially just added some test cases for symlinks in the `refs/heads` dir to
ensure this actually works (and it did), but I think it's worth having APIs.

As discussed in https://github.com/ostreedev/ostree/pull/946, the
summary file is becoming an unsigned cache of ref information; any
additional metadata for the repository needs to move elsewhere in order
to remain signed. Introduce OSTREE_REPO_METADATA_REF as the well-known
name of a ref where such metadata can live, as the metadata on
contentless commits.

Add an initial OstreeRepoFinder interface (but no implementations),
which will find remote URIs by ref names and collection IDs, the
combination of which is globally unique.
The new API is used in a new ostree_repo_find_updates() function, which
resolves a list of ref names to update into a set of remote URIs to pull
them from, which can be treated as mirrors. It is an attempt to
generalise resolution of the URIs to pull from, and to generalise
determination of the order and parallelisation which they should be

Working on `rpm-ostree livefs`, I realized though I needed to just
check out *new* files directly into the live `/etc` (and possibly
delete obsolete files).
The way the current `/etc` merge works is fundamentally different from
that. So my plan currently is to probably do something like:
- Compute diff
- Check out each *new* file individually (as a copy)
- Optionally delete obsolete files
Also, a few other things become more important - in the current deploy code, we
copy all of the files, then relabel them. But we shouldn't expose to *live*
systems the race conditions of doing that, plus we should only relabel files we
checked out.
By converting the deploy's /etc code to use this, we fix the same TODO item
there around atomically having the label set up as we create files. And further,
if we kill the `/var` relabeling which I think is unnecessary since Anaconda
does it, we could delete large chunks of code there.
In the implementation, there are two types of things: regular files, and
symlinks. For regular files, in the `O_TMPFILE` case, we have the ability to
do *everything* atomically (including SELinux labeling) before linking it into
place. So let's just use that. For symlinks, we use `setfscreatecon()`.

I was working on `rpm-ostree livefs` which does some ostree-based
filesystem diffs, and noticed that we were ending up with `/proc`
not being labeled in our base trees.
Reading the selinux-policy source, indeed we have:
```
/proc -d <<none>>
/proc/.* <<none>>
```
This dates pretty far back. We really don't want unlabeled
content in ostree. In this case it's mostly OK since the kernel
will assign a label, but again *everything* should be labeled via
OSTree so that it's all consistent, which will fix `ostree diff`.
Notably, `/proc` is the *only* file path that isn't covered when composing a
Fedora Atomic Host. So I added a hack here to hardcode it (although I'm a bit
uncertain about whether it should really be `proc_t` on disk before systemd
mounts or not).
Out of conservatism, I made this a flag, so if we hit issues down the line, we
could easily change rpm-ostree to stumble on as it did before.

For a long time we've cached the remote configs in the repo, which
mostly makes sense for the `repo/config` file, but less sense
for `/etc/ostree/remotes.d`, because we want to support admins
interactively editing them.
One can delete the repo instance and create a new one, but that's a bit ugly.
Let's introduce an API for this so rpm-ostree can reload remotes after
admins/scripts edit them in `/etc`. We also might as well reload
any other entries in the config.
Structurually now, `ostree_repo_open()` deals with file descriptors, and then
calls `ostree_repo_reload_config()`. Except for the uncompressed cache, which is
the only thing that deals with FDs that can be configured. But we want to delete
that anyways.
No tests, since...we don't have a daemon in this codebase, don't want to shave

There are use cases for having a single repo with branches
with different lifecycles; a simple example of what I was
trying to do in CentOS Atomic Host work is have "stable"
and "devel" branches, were we want to prune devel, but
retain *all* of stable.
This patch is split into two parts - first we add a low level "delete all
objects not in this set" API, and change the current prune API
to use this.
Next, we move more logic into the "ostree prune" command. This paves the way for
demonstrating how more sophisticated algorithms/logic could be developed outside
of the ostree core.
Also, the --keep-younger-than logic already lived in the commandline, so it
makes sense to keep extending it there.

This function now takes an extra flag to specify whether it should
search through remote repos. Additionally, ostree_repo_resove_rev_ext

I plan to use this in rpm-ostree at least for two reasons:
- To find the mtime on the repo
- To use the tmp/ directory to stage content (but we should eventually
add a better API)
As rpm-ostree evolves, it keeps driving API additions to libostree.
This creates a relatively tight coupling.
However, if delivering via e.g. RPM, unless one manually remembers to
increment the `Requires:` in the spec file, it's possible for the two
to become desynchronized.
RPM handles versioned symbols and will ensure a dependency if the
application starts using a newer version.
To implement this, switch to `-fvisibility=hidden`, along with an
annotation in the header, and finally add a `.sym` file.
This matches what other projects like systemd and libvirt do.
Although rather than attempting to retroactively version symbols, glom
them all onto the current one.
This is a more flexible version of the previous
ostree_repo_write_archive_to_mtree() which took a file reference.
This has an extensible options structure, and in particular
now supports `ignore_unsupported_content`.
I plan to use this for importing Docker images which contain device
nodes. (There's no reason for container images to have those, so
we'll just ignore them).
Also here, just like the export variant, the caller is responsible for
setting up libarchive.
I was going to add new API for importing, and it was really confusing
that what I think of now as import and export both had "write" in the
name. It's just clearer to talk about the direction.
At the same time, include `Export` in the options structure.
This isn't an ABI break as the API isn't in a release.
At the moment I'm looking at using rpm-ostree to manage RPM inputs
which can then be converted into Docker images. It's most convenient
if we can stream directly out of libostree rather than doing a
checkout + tar combination.
There are also backup/debugging etc. reasons to implement `export` as
well.
This is a better followup to dc9239dd7b
since I wanted to do fsync-less checkouts in rpm-ostree too, and
replicating the "turn off fsync temporarily" was in retrospect just a
hack.
We can simply add a boolean to the checkout options.

Originally, a lot of the `fsync()` calls here were added for the
wrong reason - I was chasing a bug that ended up being the extlinux
bootloader not parsing 64 bit ext4 filesystems. But since it looked
like corruption, I tried adding a lot more `fsync()` calls.
All we should have to do is use `syncfs()`. If that doesn't work,
it's a kernel bug.
I'm making this change because skipping the individual fsyncs can be a
major performance win - it's easier for the FS to optimize, we do more
in parallel, etc.

A fast way to generate new OSTree content using an existing
tree is to checkout (as hard links), add/replace files, then
call `ostree_repo_scan_hardlinks()`, then commit.
But `ostree_repo_scan_hardlinks()` scans the entire repo, which
can be slow if you have a lot of content.
All we really need is a mapping of (device,inode) -> checksum
just for the objects we checked out, then use that mapping
for commits.
This patch adds API so that callers can create a mapping via
`ostree_repo_devino_cache_new()`, then pass it to
`ostree_repo_checkout_tree_at()` which will populate it, and then
`ostree_repo_write_directory_to_mtree()` can consume it.
I plan to use this in rpm-ostree for package layering work.
Notes:
- The old `ostree_repo_scan_hardlinks()` API still works.
- I tweaked the cache to be a set with the checksum colocated with
the key, to avoid a separate malloc block per entry.

Imports one or more GPG keys from a source stream or from the user's

The imported keys are used to conduct GPG verification when pulling

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.
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.
For Anaconda, I needed OSTREE_REPO_REMOTE_CHANGE_ADD_IF_NOT_EXISTS,
with the GFile *sysroot argument to avoid ugly hacks. We want to
write the content provided via "ostreesetup" as a remote to the target
chroot only in the case where it isn't provided as part of the tree
content itself.
This is also potentially useful in idempotent systems management tools
like Ansible.

I'll be using this to "promote" builds between different repositories.
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.

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.
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.
https://bugzilla.gnome.org/show_bug.cgi?id=728351
The current "transaction" symlink was introduced to fix issues with
interrupted pulls; normally we assume that if we have a metadata
object, we also have all objects to which it refers.
There used to be a "summary" which had all the available refs, but I
deleted it because it wasn't really used, and was still racy despite
the transaction bits.
We still want the pull process to use the transaction link, so don't
delete the APIs, just relax the restriction on object writing, and
introduce a new ostree_repo_set_ref_immediate().
For many OS install scenarios, one runs through an installer which may
come with embedded data, and then the OS is configured post-install to
receive updates.
In this model, it'd be nice to avoid the post-install having to rewrite
the /ostree/repo/config file.
Additionally, it feels weird for admins to interact with "/ostree" -
let's make the system feel more like Unix and have our important
configuration in /etc.

It's better if this is independent from the OstreeSysroot; for
example, a policy is active in a given deployment root at once, not
for a sysroot globally.
We can also collect SELinux-related API in one place.
Unfortunately at the moment there can be only one instance of this
class per process.
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 will be used by guestmount - it's WAY faster. We only take disks
as a unit, so it's safe. If the process fails halfway through, we
just start over from scratch the next time anyways.
The trees as shipped come with /usr/etc, which should just be labeled
as usr_t. When we do a deployment, we need to relabel the copies of
the files we're making in /etc.
SELinux support is compile and runtime optional.
We can't use #ifdef in the headers, since then g-ir-scanner won't pick
up the functions (unless we included config.h). Let's instead always
have the symbols, but just set an error if we were built without
support for it, just like how pull works.
Several APIs in libostree were moved there from the commandline code,
and have hardcoded g_print() for progress and notifications. This
isn't useful for people who want to write PackageKit backends, custom
GUIs and the like.
From what I can tell, there isn't really a winning precedent in GLib
for progress notifications.
PackageKit has the model where the source has GObject properties that
change as async ops execute, which isn't bad...but I'd like something
a bit more general where say you can have multiple outstanding async
ops and sensibly track their state.
So, OstreeAsyncProgress is basically a threadsafe property bag with a
change notification signal.
Use this new API to move the GSConsole usage (i.e. g_print()) out from
libostree/ and into ostree/.
Add a --generate-sizes option to commit to add size information to the
commit metadata. This will be used by higher level code which wants
to determine the total size necessary for downloading.
This uses gpgv for verification against DATADIR/ostree/pubring.gpg by
default. The keyring can be overridden by specifying OSTREE_GPG_HOME.
Add a unit test for commit signing with gpg key and verifying on pull;
to implement this we ship a test GPG key generated with no password
for Ostree Tester <test@test.com>.
Change all of the existing tests to disable GPG verification.
