Fedora switched to 'xz' compress kernel modules, and recently
[RHEL7 did too](https://bugzilla.redhat.com/show_bug.cgi?id=1367496).
This compression defeats bsdiff.
While we have a "rollsum-able" test, we don't have a "bsdiff-able" test as it'd
be very expensive (we'd have to bsdiff, then apply it and compare the result).
Let's do the tactical quick fix here and just not try to delta files ending in
`.xz.`. This avoids us using bsdiff pointlessly for over 4000 files, which is
quite a notable speed increase for generating deltas.

A tricky thing here that caused this to go past a lot of our tests
is that the code was mostly OK if there was an available delta from
an older commit. But this case broke if we e.g. had a new OS
deployment and did a `--require-static-deltas` pull, i.e. the initial
state.
I cleaned up our "find static delta state" function to return an enumeration,
and extended it with an "already have the commit" state. A problem
I then hit is that we've historically fetched detached metadata for
non-delta pulls, even if the commit hasn't changed. I decided not to
do that for `--require-static-deltas` pulls for now; otherwise the
code gets notably more complex.

First, the manual crosscheck script bitrotted; it got caught up
in the "use libtest repo creation wrapper" bit, and also it
seems like at some point `pull --require-static-deltas` changed
meaning when dealing with `file:///` repos. I have more work to
unwind that.
Next, I'm seeing a delta failure which looks like a static delta
miscompilation with rollsums; change the compiler to print out
the source object too, which helped me debug this.

Directly when we allocate a new part we finish the old one,
writing the compressed data to a temporary file and generating
the delta header for it.
When all these are done we loop over them and collect the headers,
sizes and either copy the tempfile data into the inlined superblock
or link the tempfiles to disk with the proper names.
Closes: #1309
Approved by: cgwalters
This allows us to create the final delta desciptor directly on disk
rather than having it all in memory. This is nice because it can
become quite large if inlined parts are used.
Note however, that we currently generate all the delta parts in
memory before adding them to the delta, so we still keep all individual
parts in memory. Fixing that is the next step.

This is more subtle fallout from:
https://github.com/ostreedev/ostree/pull/1170
AKA commit: 8fe4536257
Before, if we found a devino cache hit, we'd use it unconditionally.
Recall that `bare-user` repositories are very special in that they're the only
mode where the on disk state ("physical state") is not the "real" state. The
latter is stored in the `user.ostreemeta` xattr. (`bare-user` repos are also
highly special in that symlinks are regular files physically, but that's not
immediately relevant here).
Since we now have `bare-user-only` for the "pure unprivileged container" case,
`bare-user` should just be used for "OS builds" which have nonzero uids (and
possibly SELinux labels etc.)
In an experimental tool I'm writing "skopeo2ostree" which imports OCI images
into refs, then squashes them together into a single final commit, we lost the
the `81` group ID for `/usr/libexec/dbus-1/dbus-daemon-launch-helper`.
This happened because the commit code was loading the "physical" disk state,
where the uid/gid are zero because that's the uid I happened to be using. We
didn't just directly do the link speedup because I was using `--selinux-policy`
which caused the xattrs to change, which caused us to re-commit objects from the
physical state.
The unit test I added actually doesn't quite trigger this, but I left
it because "why not". Really testing this requires the installed test
which uses SELinux policy from `/`.
The behavior without this fix looks like:
```
-00755 0 0 12 { [(b'user.ostreemeta', [byte 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x51, 0x00, 0x00, 0x81, 0xed]), (b'security.selinux', b'system_u:object_r:lib_t:s0')] } /usr/lib/dbus-daemon-helper
```
which was obviously totally broken - we shouldn't be picking up the
`user.ostreemeta` xattr and actually committing it of course.

This is a freeform string useful to track/display when a commit is "derived"
from some other format. For example, in the rpm-ostree test we make a

`fedora-atomic:fedora/26/x86_64/atomic-host`.
My current patch sets the source title to e.g.
"Dev overlay on fedora-atomic:fedora/26/x86_64/atomic-host".
Another case I'm working on now is importing OCI images to use
as host images. For that case, the source title is

I'm playing around with some ostree ⇔ OCI/Docker bits, and ran
into this while importing an OCI image that built from the Fedora
base image where `/home` is a regular directory, and I added a layer
that did the ostree bits of moving it to `/var` and leaving a symlink.
OCI/Docker supports this. Now since "process whiteouts" is really the
"enable OCI/Docker" mode, let's only replace dirs if that's enabled.
This leaves the `UNION_FILES` targeted for its original use case
which is unioning components/packages. (Although that use case itself
is now a bit superceded by `UNION_IDENTICAL`, but eh).

Change the regexp for validating refs to require at least one letter or digit
before allowing the other special chars in the set `[.-_]`. Names that start
with `.` are traditionally Unix hidden files; let's ignore them under the
assumption they're metadata for some other tool, and we don't want to
potentially conflict with the special `.` and `..` Unix directory entries.
Further, names starting with `-` are problematic for Unix cmdline option
processing; there's no good reason to support that. Finally, disallow `_` just
on general principle - it's simpler to say that ref identifiers must start with
a letter or digit.
We also ignore any existing files (that might be previously created refs) that
start with `.` in the `refs/` directory - there's a Red Hat tool for content
management that injects `.rsync` files, which is why this patch was first
written.
V1: Update to ban all refs starting with a non-letter/digit, and
also add another call to `ostree_validate_rev` in the pull
code.

The way `_ostree_repo_open_content_bare()` did both looking for the object and
possibly creating a new fd was just weird and inconsistent with e.g. the pull
code where we always call `has_object()` first.
Just call `has_object()` in the delta paths that used this too, making the
implementation right now a thin wrapper around
`glnx_open_tmpfile_linkable_at()`, but this is prep for a later patch which does
more.

For checkouts that are on the same device, for regular files we can simply
"adopt" existing files. This is useful in the "build from subtrees" pattern that
happens with e.g. `rpm-ostree install` as well as flatpak and gnome-continuous.
New files are things like an updated `ldconfig` cache, etc. And particularly for
`rpm-ostree` we always regenerate the rpmdb, which for e.g. this workstation is
`61MB`.
We probably should have done this from the start, and instead had a `--copy`
flag to commit, but obviously we have to be backwards compatible.
There's more to do here - the biggest gap is probably for `bare-user` repos,
which are often used with things like `rpm-ostree compose tree` for host
systems. But we can do that later.

I was working on a patch to do build on the work done to
import content objects async to do the same for metadata, but right
now we basically rely on writing them first to do the GPG verification
when scanning.
Things will be cleaner for that if we can pass the commit object directly into
`scan_commit_object()` and consistently use `gpg_verify_unwritten_commit()`.
We're careful here to continue to do it both ways (but at most one time), to
account for the case where a bad commit has been pulled and written - we need to
keep failing GPG verification there.
Closes: #1269

There's a subtle issue going on with the way we use `UNION_IDENTICAL`
now in rpm-ostree. Basically, the crux of the issue is that we checkout
the whole tree from the system repo, but then overlay packages by
checking out from the pkgcache repo. This is an easy way to break the
assumption that we will be merging hardlinks from the same repo.
This ends up causing issues like:
https://github.com/projectatomic/rpm-ostree/issues/1047
There, `vim-minimal` is already part of the host and has an object for
`/usr/share/man/man1/ex.1.gz`. `vim-common` has that same file, but
because it's unpacked in the pkgcache repo first, the hardlinks are not
the same.
There are a few ways we *could* work around this in rpm-ostree itself,
e.g. by re-establishing hardlinks when we do the content pull into the
system repo, but it still felt somewhat hacky. Let's just do this the
proper way and fall back to checksumming the target file if needed,
which is what librpm does as well in this case. Note that we only
checksum if they're not hard links, but they're the same size.
