Improve the heuristic to use only the part before the first '.' when
looking for a similar file in the current directory.
last versions of dracut generate reproducible initramfs files, but we
still fallback to the full file download if there is any minimal
change that causes a different checksum and file name.
This change extends that case to deal better with similar files that
have a different suffix.
This is the difference generating a static delta from

Clang has better detection for unused vars when using auto cleanup
functions. We should eventually just fold this back into the first
testsuite. But let's just turn it on for now, at least until it's
satisfied with the whole codebase.

I'm doing builds and `make check` inside a Docker container, with
selinux on as a build-time option, but no policy in the container.
This currently aborts. Let's not do that.

If we have a partial commit it is not an error for a dirmeta to be
missing (in fact, that is likely), so instead of returning a not-found
error from ostree_repo_traverse_commit() we ignore the error and
continue.
In particular, this means we don't stop early at the first
missing dirmeta, which previously caused ostree_repo_prune() to
thing the dirmetas after that to be unreached and thus purged.
Also, we remove the special casing in ostree_repo_prune() to
not report errors for commitpartial, because these should not
be reported anymore.

If there is a transaction active, then we put writes to detached
metadata into the staging dir, and when reading it we look there
first. This allows transactions to be aborted half-way without
writing the detached metadata into the repository (possibly
overwriting any old metadata from there).
This fixes https://github.com/ostreedev/ostree/issues/526Closes: #539

If the detached metadata is not in the repo, try in the parent
repo if that is set.

Commit 1d4f1b8878addd28059c3a3928640491755cd615 started using hardlinks
checkouts of symlinks. However, symlinks are not stored as symlink in the
repo for bare-user repos, so this breaks user-mode checkouts of such repos.
We fix this by checking for !is_symlink in the bare-user case.

Add a YAML file for the new Red Hat CI framework.
Rather than re-installing all the build deps everytime, which takes
time, I added a Dockerfile that we can wire up to the Docker Hub. For
now it lives at `jlebon/ostree-tester:rhci`, but we can move it under
the `projectatomic` org (or a new `ostree` org).
Closes: #535
Approved by: cgwalters
I was noticing a recent performance issue with checkouts
which seemed to be mostly us going back to doing a `fsync()` on
directories.
Regardless, while looking at that, I saw we were spending time
creating new symlinks. Even though symlinks are small, it's still
better to hardlink them.
Going way back in time, the reason we weren't doing this is
because we were hitting `EMFILE` on ext4, but that was for
gnome-continuous which creates *many* build roots. Even
there though, they're just a cache, and we handle `EMFILE`.
For ostree-for-host-system, we don't expect to have many roots (just 3
at most transiently), so hardlinking symlinks does make sense.

Just noticed this while inspecting the code. The deployments retrieved
by `_ostree_sysroot_list_deployment_dirs_for_os` will forcibly already
have a matching osname since it indirectly uses that same variable to
construct them. Having a check there makes it look like there may be
subtle corner cases, when there aren't.
Closes: #529
Approved by: cgwalters
I was confused while reading the docs how this could work, since in at
least the Fedora/CentOS/RHEL distros, they're named e.g.
initramfs-`uname -r`-$checksum.

If this is true, don't initiate, abort of commit a transaction, instead
it is assumed that the caller initiated the transaction, and that it
will eventually be commited.
This allows you to do multiple pulls or a combination of pulls and
commits in a single transaction.

This pulls in a new compilation flag for wrpseudo compatibility. Also
note we need to add some includes since glnx-libcontainer went away,
and with it some includes for `sys/mount.h` etc.

We were seeing some weird potential memory corruption in this code
when using it for `rpm-ostree-toolbox installer`, which is almost
certainly not its fault, but let's use it as an excuse to port
(mostly) to fd-relative and away from GFile.
Dropping the last GFile use here is a bit tricky as it does have a
nice high level wrapper around inotify.
Closes: #512

My previous change in https://github.com/ostreedev/ostree/pull/425
actually broke things so we basically used the repository defaults =(
This is a subtle mess since we're only trying to flip things off
for the *new* API.
Clean this up so that the "default repo inheritance" lives only in one
place - in the compat layer for the old checkout API. The new
checkout API defaults to off period, so the repository state is
irrelevant.

/var/log is another one of those core directories that should be made

While looking at a slow update issue (which I'm guessing is
unpredictable I/O latency in an OpenStack instance), I noticed
in one of the traces we were inside a fsync here.
Dropping the fsync here is just another of a long series of unwinding
them - we `syncfs()` the sysroot fd and `/boot` and we have a big
`sync()` anyways.
Closes: #508
Approved by: jlebon
More fsync pruning. Since we have a public API for writing the origin
file and it did a fsync before, let's preserve that. But when writing
deployments as part of a full transaction, we rely on the global
`syncfs()`, so add an internal function for origin file writing that
doesn't.

If ostree_sysroot_unload() was called explicitly, then sysroot_fd
would be closed again at finalization time, possibly closing a
random file descriptor belonging to some other part of the
application.

0 was used as an "unset" flag for tmp_dir_fd, which is technically
incorrect. For cache_dir_fd, -1 was used as the sentinal but 0
was checked for, resulting in close(-1).

In https://github.com/ostreedev/ostree/pull/408 we fixed a
bug where we would crash when trying to execute deltas into
an archive repo (which isn't presently supported).
But that was overly aggressive - we obviously *can* execute deltas
when mirroring into a bare repo. This should fix a regression with
the way flatpak uses mirroring to pull from a user repo into the
system.
Closes: #506

This way e.g. flatpak can detect which timestamp it should use.

Since forever, we've been doing two cleanups. In
8ece4d6d51
I thought we were doing just one and wanted to go to zero (if specified),
but I actually just dropped one cleanup.
In https://github.com/projectatomic/rpm-ostree/pull/452
@jlebon pointed out the duplication. Fix this by creating a new internal
deploy wrapper that takes cleanup flags.
(Since we already had the "piecemeal cleanup" API internally, let's
frame it in terms of that, rather than passing down a boolean).
Closes: #500
Approved by: jlebon
If the current repo is already up to date (we have no content to
fetch), it's possible for the fetcher to not request any URIs. So
create and then finalize it quickly.
Finalization involves calling `g_main_loop_quit()` +
`g_thread_wait()`. However, if `g_main_loop_quit()` is run *before*
`g_main_loop_run()`, we'll deadlock because GMainLoop assumes in
`_run()` to start things.
This is a common trap - ideally, GMainLoop would record if `_quit()`
was called before `_run()` or something, but doing that now would
likely break people who are expecting quit() -> run() to restart.
In general, we've moved in various GLib-consuming apps to an
explicit "main context iteration with termination condition" model;
see `pull_termination_condition()` in the pull code.
This fixes this race condition.
I verified that an assertion in `_finalize` that more than
zero URIs were requested was hit in multiple test cases, and this patch
has survived a while of make check loops.

Quoting Dan Nicholson in
<https://github.com/ostreedev/ostree/pull/330#issuecomment-245499099>
mtime of 0 has been the semantics of ostree deployments from basically
the beginning of the project. We (and others, see
flatpak/flatpak@b5204c9) rely on that fact when generating trees.
In particular, this affects caches that use the mtime of the
associated file or directory to determine if the cache is valid. By
arbitrarily changing the mtime of the files to something else, all
the caches we setup in the build are now invalidated. Preseeding
caches is really important to the user experience as it avoids
having the user wait while they're regenerated on first run.
Now, we could change our build infrastructure to preset all the
mtimes to 1 to match this change, but what does that do for our
existing users who are on an ostree that deploys with mtimes of 0?
We could just revert this change at Endless (and the associated one
in Flatpak), and that would be fine for our users. However, if we
point non-Endless users to our apps, they'll have the great
experience of waiting 10 seconds the first time they launch it while
the fontconfig cache is rebuilt unnecessarily.
