Eliminates the need for constantly passing --sysroot=sysroot, but
also makes ostree place remote configs for sysroot/ostree/repo in
sysroot/etc/ostree/remotes.d where they should have been all along.
I did a quick audit pass through the pull code. What I focused on the
most is the case where `gpg-verify-summary=true`, and in particular
where `gpg-verify=false` too. This should be a valid and secure
configuration.
The primary change here is to error out very quickly if either
`summary` or `summary.sig` are 404. Previously, we'd only error out
if we were processing deltas.
Expand the existing test case to cover this, plus invalid summary and
invalid sig. (The test case was failing with current git master too).
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.
This reverts commit d3545b0661f3247cd8c106e64a71052ce9952243. Since the
test is now using the temporary copy of the gpg homedir, it is no longer
owned by root.
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".
Just noticed this while debugging something else. We don't want to
commit the whole test dir, just the workdir.
Trying to commit the repo itself is potentially subject to race
conditions at least.
Having undefined (but in practice rarely changing) ordering for
`readdir()` ended up screwing us over for bootloader config
generation; see https://bugzilla.redhat.com/show_bug.cgi?id=1226520
Let's make things significantly more likely to fail more quickly in
the future if similar bugs are introduced. We accomplish this by
introducing a little `LD_PRELOAD` library that randomizes the results
of `readdir()`.

One can run this on a machine to validate things. I'd like to
get this plugged into the actual OSTree tests as soon as we can
figure out how to sanely run grub2-generate as non-root in
our test suite.
Alternatively, this script can easily be run on a real install.
External daemons like rpm-ostree want push notification any time a
change is made by an external entity. inotify provides notification,
but a problem is there's no easy way to monitor all of the refs.
In the past, there has been discussion of opt-in recursive timestamps:
https://lkml.org/lkml/2013/4/5/307
But in today's world, let's just bump the mtime on the repo itself, as
a central inotify point.

When I removed the `transaction` symlink, that made this test start
failing. Fix it by doing `chmod` on `repo/objects`, which is what the
core `ostree_repo_is_writable()` looks at.
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.
Always request detached metadata for commit objects, even if we already
have the commit object. This ensures we fetch any post facto detached
metadata updates such as new GPG signatures.

First, git doesn't do this, and whatever Linus thinks is right or
something.
Second specifically to OSTree, it's quite common to not have
intermediate commits. If one wants to reset a ref in order to prune
data after a deployment, the parentage check will fail.

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.
