There are a few cases for knowing whether a commit has identical
content to another commit. Some people want to do a "promotion workflow",
where the content of a commit on a tesitng branch is then "promoted"
to a production branch with `ostree commit --tree=ref`.
Another use case I just hit in rpm-ostree deals with
[jigdo](https://github.com/projectatomic/rpm-ostree/issues/1081) where we're
importing RPMs on both the client and server, and will be using the
content checksum, since the client/server cases inject different metadata
into the commit object.

This is analogous to the filtering support for the commit API: we allow
library users to skip over checking out specific files. This is useful
in some tricky situations where we *know* that the files to be checked
out will conflict with existing files in subtle ways.
One such example is in rpm-ostree support for multilib. There, we want
to allow checking out a package onto an existing tree, but skipping over
files that are not coloured to our preferred value (e.g. not overwriting
an i686 version of `ldconfig` if we already have the `x86_64` version).
See https://github.com/projectatomic/rpm-ostree/pull/1227 for details.

SPDX License List is a list of (common) open source
licenses that can be referred to by a “short identifier”.
It has several advantages compared to the common "license header texts"
usually found in source files.
Some of the advantages:
* It is precise; there is no ambiguity due to variations in license header
text
* It is language neutral
* It is easy to machine process
* It is concise
* It is simple and can be used without much cost in interpreted
environments like java Script, etc.
* An SPDX license identifier is immutable.
* It provides simple guidance for developers who want to make sure the
license for their code is respected

Clients of libostree such as rpm-ostree make extensive use of the
`ostree commit -b foo --tree=ref=foo` pattern in their tests, e.g. to
simulate an update.
What I'm trying to solve here is that it's often the case that we want
to keep metadata from the previous commit without having to be too
verbose (i.e. reading from the parent, then passing it as an argument).
The new `--keep-metadata` switch makes this really easy. I intend to use
this in the rpm-ostree testsuite to make sure we always carry over the
`source-title` metadata as well as during set up for tests that require
`rpmostree.rpmdb.pkglist` metadata.
I initially implemented this in a small wrapper script that uses the API
directly, though we make use of so many other `ostree commit` functions
that it'd require re-implementing a lot of it.
Closes: #1402
Approved by: cgwalters
We had this basically forced on in the CLI; down the line I'd really like to
make this an API option to commit or so, but given that we found a use case in
the rpm-ostree test suite for "unbound" commits, let's support creating them
from the cmdline.
See: https://github.com/ostreedev/ostree/pull/1379Closes: #1380
Approved by: jlebon
Mostly adding this for use in test cases; it allows us to add e.g.
integers, and we need to deal with byteswapping those.
Someone mind also find it useful to add fully structured metadata, although most
of those users should be using a real language and not shell script.

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).
Closes: #1294
Approved by: jlebon
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.
Closes: #1272
Approved by: jlebon
I was working on "adopt" and hit corruption; turns out we were missing the
`--canonical-permissions` arg in this existing test.

Closes: #1272
Approved by: jlebon
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.
Closes: #1258

In case a filename contains invalid UTF-8 characters, libostree will
pass it to g_variant_builder_add() in create_tree_variant_from_hashes()
anyway, which leads to a critical warning from glib and an invalid
commit. This commit makes ostree print a useful error and exit instead.

This is like `ostree_checksum_file` but fd-relative. This will be used

Add a basic one here to test the old code as well as the new code.

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.
Closes: #1255
Approved by: jlebon
We can't use the cache if the file we want to commit has been modified
by the client through the file info or xattr modifiers. We would
prematurely look into the cache in `write_dfd_iter_to_mtree_internal`,
regardless of whether any filtering applied.
We remove that path there, and make sure that we only use the cache if
there were no modifications. We rename the `get_modified_xattrs` to
`get_final_xattrs` to reflect the fact that the xattrs may not be
modified.
One tricky bit that took me some time was that we now need to store the
st_dev & st_ino values in the GFileInfo because the cache lookup relies
on it. I'm guessing we regressed on this at some point.
This patch does slightly change the semantics of the xattr callback.
Previously, returning NULL from the cb meant no xattrs at all. Now, it
means to default to the on-disk state. We might want to consider putting
that behind a flag instead. Though it seems like a more useful behaviour
so that callers can only override the files they want to without losing
original on-disk state (and if they don't want that, just return an
empty GVariant).

Keep track of how many objects we imported, and print that for `ostree
pull-local` (also do this even if noninteractive, like we did for `pull`).
In implementing this at first I used separate variables for import
from repo vs import from localcache, but that broke some of the
tests that checked those values.
It's easier to just merge them; we know from looking at whether or not
`remote_repo_local` is set whether or not we were doing a "HTTP pull with
localcache" versus a true `pull-local` and can use that when rendering status.

Our CI uses default Docker, which has SELinux labeling but is rather
evil in returning `EOPNOTSUPP` to any attempts to set `security.selinux`,
even if to the same value.
The previous fire 🔥 for this was: https://github.com/ostreedev/ostree/pull/759
The `bare` repo mode really only makes sense as uid 0, so our installed
test framework is a good match for this. However, the unit tests *do*
work in a privileged container even as non-root, and *also* should
work on SELinux-disabled systems. So let's teach the test framework
how to skip in those situations.
I tested this both in a priv container (my default builder) and an unpriv
container (like our CI).
At the same time, start executing the `test-basic.sh` from an installed test,
so we get better coverage than before.
This is just the start - all of the sysroot tests really need the
same treatment.

Conceptually `ostree-repo-pull.c` should be be written using
just public APIs; we theoretically support building without HTTP
for people who just want to use the object store portion and
do their own fetching.
We have some nontrivial behaviors in the pull layer though; one
of those is the "bareuseronly" verification. Make a new internal
API that accepts flags, move it into `commit.c`. This
is prep for further work in changing object import to support
reflinks.

There are use cases for not syncing at all; think build cache repos, etc. Let's
be consistent here and make sure if fsync is disabled we do no sync at all.
I chose this opportunity to add tests using the shiny new strace fault
injection. I can forsee using this for a lot more things, so I made
the support for detecting things generic.

It turns out that librpm automatically merges identical files between
distinct packages, and this occurs in practice with Fedora today between
`chkconfig` and `initscripts` for exmaple.
Since we added this for rpm-ostree, we basically want to do what librpm does,
let's change the semantics to do a merge. While we're here rename
to `UNION_IDENTICAL`.

Previously, we only supported additions in the statoverride file;
it was mainly for adding the setuid bit without having that physically
on disk.
However, for testing a change to `bare-user` handling around *unreadable*
files (which happens for `/etc/shadow` in host content), I need a way
to write that into a repo in the test suite.
I'm not actually aware of a non-test-suite use case for this; a more
sophisticated user is going to be using the API directly, which can already do
this. But we need it for tests at least.

These are tuples of (collection ID, ref name) which are a globally-unique
form of local ref. They use OstreeCollectionRef as an identifier, and hence
need to be accessed using new API, as the existing API uses string
identifiers and sometimes accepts refspecs. Remote names are not
supported as part an OstreeCollectionRef.

those repo modes locally for build systems.

Having every object in a bare-user repo (and checkouts) be executable
is ugly. I can't think of a good reason to do that; they should only
be executable if their input is. This does
for `bare-user` what we did for `bare-user-only` in
https://github.com/ostreedev/ostree/pull/909
It's also a stronger version of what we do with `checkout -U` in suppressing
suid - here we also strip world-writable files and the sticky bit (even though
that's meaningless today, it might not be in the future).

For the flatpak use case where bare-user-only was introduced, we actually
don't want to support s{u,g} id files in particular.
Actually, I can't think of a reason to have anything outside of the
`0755 i.e. (u=rwx,g=rx,o=rx)` mask, so that's what we do here.
This will have the effect of treating existing `bare-user-only` repositories as
corrupted if they have files outside of that mask, but I think we should do this
now; most of the flatpak users will still be on `bare-user`, and we haven't
changed the semantics of that mode yet.
Note that in this patch we will also *reject* file content that doesn't
match this. This is somewhat asymmetric, since we aren't similarly rejecting
e.g. directory metadata. But, this will close off the biggest source
of the problem for flatpak (setuid binaries).

This is what caused the merge of
https://github.com/projectatomic/rpm-ostree/pull/652
to blow up, since https://github.com/ostreedev/ostree/pull/848
landed right before we tried to merge it.
When I was writing that PR I remember having an uncertain feeling
since we were doing a `mkdirat` above, but at the time I thought
we'd have test suite coverage...turns out we didn't.
For backwards compatibility, we need to continue to do a `mkdirat` here of the
parent. However...I can't think of a reason anyone would *want* that behavior.
Hence, let's add a special trick - if the destination name is `.`, we skip
`mkdirat()`. That way rpm-ostree for example can open a dfd for `/etc` and avoid
the `mkdir`.
Fold the subpath tests into `test-basic.sh` since it's not worth a separate
file. Add a test case for checking out a file.

There are a lot of things suboptimal about this approach, but
on the other hand we need to get our CI back up and running.
The basic approach is to - in the test suite, detect if we're on overlayfs. If
so, set a flag in the repo, which gets picked up by a few strategic places in
the core to turn on "ignore xattrs".
I also had to add a variant of this for the sysroot work.
The core problem here is while overlayfs will let us read and
see the SELinux labels, it won't let us write them.
Down the line, we should improve this so that we can selectively ignore e.g.
`security.*` attributes but not `user.*` say.
