I was trying to use this with pygobject for an OCI+ostree project, and pygobject
rejected simply assigning to the field (understandably, since it can't bind the
lifetime together).
Add a wrapper function, which is still unsafe, but hides that unsafety
where most people shouldn't find it. And if they do...well, sorry,
Rust wasn't invented when ostree was started.

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is now a bit superceded by `UNION_IDENTICAL`, but eh).

This is similar idea as
5c0bf88915,
The duplicated description is now removed, and the description
of the command is now displayed beneath the Usage.
For example:
ostree cat -h will output the following:
"Usage:
ostree cat [OPTION?] COMMIT PATH...
Concatenate contents of files"

This is a similar approach as
12c34bb249.
One thing to note is when we parse the admin related functions,
we still keep the old admin related flags, and added a new parameter
to represent the command struct.
This allows us to identify the caller of the function, making it
easier for us to possibly deduplicate the subcommand handling in
the future. A similar approach is done in rpm-ostree:
83aeb018c1
This also makes it easier for us to change the prototype of the function.
If we want to add something new in the future, we won't need to touch every prototype.
Closes: #1267

Added a description argument to all type
of commands. Now when we include -h or --help
for commands that contain subcommands, the description
for those subcommands are shown.
The added subcommands help will be provided to the following commands:

- ostree admin -h
- ostree admin instutil -h
- ostree remote -h
- ostree static-delta -h

This is another OstreeRepoFinder implementation; it returns results from
a given set of URIs. It’s designed to be used for implementing user
overrides to other repo-finders, or for implementing unit tests.

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 string needs to be escaped with a $ since we want to replace the
literal string $(path). Without this make will run the command with the
value of the variable, which won't match anything in the input Makefile

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.

This is another case where making an input stream out of a memory buffer is a

A side effect of commit 8fe4536257 is that
we started listing all xattrs even for files with device/inode matches;
further, we did that using the dfd/name which means we went through
the `/proc` path, which is slower and uglier.
Noticed this in strace while looking at adoption code.

I was going to fix a bug in the static deltas code and I noticed
we were missing `pull-test.sh` coverage for bareuseronly 🙈.
Obviously fixing this requires duplicating some of the bits we have in
`basic-test.sh`; need to hoist that into `libtest.sh`. For now though let's get
the coverage.

This isn't perfect, but at least we fix an error-overwrite error, and in

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.

The intended use was to have the .am.inc generated from the .am like the
libglnx one. Without this, make was detecting a circular dependency and

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
Approved by: jlebon
Prep for a later patch to do GPG verification before writing commit objects;
`_ostree_repo_gpg_verify_with_metadata()` already handles this, and so dropping
this gives us consistent error messages.

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.

In case a filename contains invalid UTF-8 characters, libostree will
pass it to g_variant_builder_add() in create_tree_variant_from_hashes()

- {

It's no longer called directly by the pull code, so make it static.

This simplifies a lot of code; the header function was structured
to write to an input stream, but many callers only wanted the checksum,
so it's simpler (and error-free) to simply allocate a whole buffer
and checksum that.
For the callers that want to write it, it's also still simpler to allocate the
buffer and write the whole thing rather than having this function do the
writing.
A lot of the complexity here again is a legacy of the packfile code, which is
dead.
This is prep for faster regfile commits where we can avoid `G{In,Out}putStream`.
Closes: #1257

Nothing was using the `bytes_written` data (we always discard partially written
tmpfiles), so simplify everything by dropping it. Further, we always passed an
offset of `0`, so drop that argument too. (I believe that this was previously
used by the "pack files" code that we deleted long ago)
Second, we had an unnecessary internal wrapper for this function; drop that too.

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.
Closes: #1260
Approved by: cgwalters
The faster (OpenSSL/GnuTLS) code lived in a `GInputStream` wrapper, and that
adds a lot of weight (GObject + vtable calls). Move it into a simple
autoptr-struct wrapper, and use it in the metadata path, so we're
now using the faster checksums there too.
This also drops a malloc there as the new API does hexdigest in place to a
buffer.
Prep for more work in the commit path to avoid `GInputStream` for local file
commits, and ["adopting" files](https://github.com/ostreedev/ostree/pull/1255).
Closes: #1256
Approved by: jlebon
For many cases of commit, we can actually optimize things by simply "adopting"
the object rather than writing a new copy. For example, in rpm-ostree package
layering.
We can only make that optimization though if we take ownership of the file. This
commit hence adds an API where a caller tells us to do so. For now, that just
means we `unlink()` the files/dirs as we go, but we can now later add the
"adopt" optimization.
