Currently if you want to update a non-alias ref, you need to first check
if it exists and use either `ostree refs --create` or `ostree reset` as
appropriate. That's unnecessarily complicated and is much less
convenient than the old `write-refs` builtin that simply called
`ostree_repo_set_ref_immediate()` without any checks.
Add a `--force` option to be used with `--create` that does not raise an
error when the destination ref already exists.

This uses the OSTREE_REPO_REMOTE_CHANGE_REPLACE operation to add a
remote or replace an existing one. This is roughly the opposite of
--if-not-exists and will raise an error if both options are passed.
Closes: #1166
Approved by: cgwalters
Add the OSTREE_REPO_REMOTE_CHANGE_REPLACE operation to the
OstreeRepoRemoteChange enum. This operation will add a remote or replace
an existing one. It respects the location of the remote configuration
file when replacing and the remotes config dir settings when adding a
new remote.

The idea is that if the process is running as root, it can change
ownership of newly written files to match the owner of the repo.
Unfortunately, it currently applies in the other direction, too - a
non-root user writing to a root owned repository. If the repo is
writable by the user but owned by root, it can still create files and
directories there, but it can't change ownership of them.
This feature comes from
https://bugzilla.gnome.org/show_bug.cgi?id=738954. As it turns out, this
feature was never completed. It only works on content objects and not
metadata objects, refs, deltas, summaries, etc. Rather than try to fix
all of those, remove the feature until someone has interest in
completing it.

Add an invalid-cache test error flag to ensure that the code that checks
for and recovers from a corrupted summary cache is hit. This helps make
sure that the recovery path is actually used without resorting to
G_MESSAGES_DEBUG.
Closes: #1698
Approved by: cgwalters
If for some reason the cached summary doesn't match the cached signature
then fetch the remote summary and verify again. Since commit c4c2b5eb
this is unlikely to happen since the summary will only be cached if it
matches the signature. However, if the summary cache has been corrupted
for any other reason then it's best to be safe and fetch the remote
summary again.
This is essentially the corollary to c4c2b5eb. Where that commit helps
you from getting into the corrupted summary cache in the first place,
this helps you get out of it. Without this the client can get wedged
until a prune or the remote server republishes the summary.
Closes: #1698
Approved by: cgwalters
There have been subtle bugs in the past when a client pulls while the
remote server is updating the summary. The client may get the old
summary and new signature or vice versa. Add tests to simulate this
behavior to make sure there aren't regressions in the future.

Systemd units using ConditionNeedsUpdate run if the mtime of .updated in
the specified directory is newer than /usr. Since /usr has an mtime of
0, there's no way to have an older .updated file. Systemd units
typically specify ConditionNeedsUpdate=/etc or ConditionNeedsUpdate=/var
to support stateless systems like ostree.
Remove the file from the new deployment's /etc and the OS's /var
regardless of where they came from to ensure that these systemd units
run when booting new deployments. This will provide a method to run

Define an auto cleanup handler for use with repo locking. This is based
on the existing auto transaction cleanup. A wrapper for
ostree_repo_lock_push() is added with it. The intended usage is like so:
g_autoptr(OstreeRepoAutoLock) lock = NULL;
lock = ostree_repo_auto_lock_push (repo, lock_type, cancellable, error);
if (!lock)
return FALSE;
The functions and type are marked to be skipped by introspection since I
can't see them being usable from bindings.
Closes: #1343
Approved by: cgwalters
Currently ostree has no method of guarding against concurrent pruning.
When there are multiple repo writers, it's possible to have a pull or
commit race against a prune and end up with missing objects.
This adds a file based repo locking mechanism. The intention is to take
a shared lock when writing objects and an exclusive lock when deleting
them. In order to make use of the locking throughout the library in a
fine grained fashion, the lock acts recursively with a stack of lock
states. If the lock becomes exclusive, it will stay in that state until
the stack is unwound past the initial exclusive push. The file locking
is similar to GLnxLockFile in that it uses open file descriptor locks
but falls back to flock when needed.
The lock also attempts to be thread safe by storing the lock state in
thread local storage with GPrivate. This means that each thread will
have an independent lock for each repository it opens. There are some
drawbacks to that, but it seemed impossible to manage the lock state
coherently in the face of multithreaded access.
The API is a push/pop interface in accordance with the recursive nature
of the locking. The push interface uses an enum that's translated to
LOCK_SH or LOCK_EX as needed. Both interfaces use an internal timeout
field to decide whether to manage the lock in a blocking or non-blocking
fashion. The intention is to allow ostree applications as well as
administrators to control this timeout. For now, the default is a 30
second timeout.
Note that the timeout is handled synchronously in thread since the lock
is maintained in thread local storage. I.e., the thread that acquires
the lock needs to be the same thread that runs the operation. There may
be a way to offer an asynchronous version, but it's not clear exactly
how that would work since it would likely involve a separate thread that
invokes a callback when the locking operation completes.

Set the PYTHONUNBUFFERED environment variable during tests so that
python leaves stdout unbuffered. This is helpful when reading logs for

If the filesystem is already frozen, FIFREEZE returns EBUSY, and if the
filesystem is already thawed, FITHAW returns EINVAL. It's very unlikely
these issues would arise on a real ostree system since the sysroot would
be locked during the freeze/thaw cycle.
However, when multiple fake sysroots are used during the test suite (run
as root), the tests could race to run the freeze/thaw cycle without
locking. Furthermore, there's no reason why an independent process might
be trying to freeze the filesystem while ostree was deploying. Ignore
but warn for these errors since there's not much ostree can do about it,
anyways.

If the new configuration passed to ostree_write_config () tries to

This option allows a repo to explicitly opt out of adding new remotes in
a remotes configuration directory. This currently defaults to true for
system repos and false for non-system repos to maintain legacy behavior
that non-system repos don't add remotes in a configuration directory.
That would be problematic for flatpak, which specifies a remotes config
dir but adds remotes in ways that are incompatible with it.
So, what this really does is allow system repos to control whether they
want to add remotes in the config dir or not. That's important if your
flatpak repo is the system repo like at Endless.

adding back the ostree_repo_is_system() check when adding remotes.

For local pulls there's no benefit pulling the static delta over the

test-lzma builds a copy of the compressor and decompressor directly, so
the compiler needs access to the LZMA headers and the linker needs to
link the program with liblzma.
libtest always makes a copy of the gpghome directory to the test
directory, so there's no need to operate on the installed copy. This
allows test-remote-gpg-import to pass as an unprivileged user since it
otherwise couldn't create the temp files gpgme creates.
On 32 bit systems, _FILE_OFFSET_BITS will be set to 64 by
AC_SYS_LARGEFILE. This causes the glibc headers to use readdir64 rather
than readdir. Emulate that behavior in the preloader or the tests will
all fail with "No such file or directory".
This test uses gpgme directly to verify the signatures, so it needs to
find the gpgme headers and link with gpgme to ensure the linker can
resolve the symbols.
The object count comes from g_hash_table_size(), so it's not a 0 based
index. In order to maintain the mod calculations correctly, just print
out index + 1.
