ostree_repo_list_static_delta_names() tried to validate that
any second-level directory element was a directory, but there was
a cut-and-paste issue, and it used `dent->d_type` instead
of `sub_dent->d_type`.
This fixes the code, but all old ostree versions will break if
there are non-directories in a subdirectory of the deltas directory
in the repo, so be wary.
Looking at
https://github.com/coreos/coreos-assembler/issues/1703
a user is getting a bare:
`error: fsetxattr: Permission denied`
I don't think it's these code paths since a deploy
isn't happening but on inspection I noticed we didn't
have error prefixing here.
When we remount `/sysroot` as read-only, we also make `/etc` read-only.
This is usually OK because we then remount `/var` read-write, which also
flips `/etc` back to read-write... unless `/var` is a separate
filesystem and not a bind-mount to the stateroot `/var`.
Fix this by just remounting `/etc` read-write in the read-only sysroot
case.
Eventually, I think we should rework this to set everything up the way
we want from the initramfs (#2115). This would also eliminate the window
during which `/etc` is read-only while `ostree-remount` runs.
We were bind-mounting the initramfs' `/etc` (to itself) instead of the
target deployment `/etc` (to itself). Since we're already `chdir`'ed
into it, we can just drop the leading slash.
Don't mention deprecation in the description for
`ostree_sysroot_deploy_tree` since there are legitimate use cases for it
(e.g. to create the first deployment via `ostree admin deploy`).
Instead, make the comment clearly redirect to the staging API when
booted into the sysroot.
Tighten up how we handle kargs here so it's more clear. When we call
`sysroot_finalize_deployment`, any karg overrides have already been set
on the bootconfig object of the deployment. So re-setting it here is
redundant and confusing.
Without reproducible images, a rebuild of the initrd will create a
different image file (due to things like creation time of the files in
the cpio archive) even if the actual contents in it are exactly the
same, adding an unnecessary download during updates.
Adding 'reproducible=yes' avoids this and creates the same image files
for the same content.
I was thinking a bit more recently about the "live" changes
stuff https://github.com/coreos/rpm-ostree/issues/639
(particularly since https://github.com/coreos/rpm-ostree/pull/2060 )
and I realized reading the last debates in that issue that
there's really a much simpler solution; do exactly the same
thing we do for `ostree admin unlock`, except mount it read-only
by default.
Then, anything that wants to modify it does the same thing
libostree does for `/sysroot` and `/boot` as of recently; create
a new mount namespace and do the modifications there.
The advantages of this are numerous. First, we already have
all of the code, it's basically just plumbing through a new
entry in the state enumeration and passing `MS_RDONLY` into
the `mount()` system call.
"live" changes here also naturally don't persist, unlike what
we are currently doing in rpm-ostree.
These allow the `summary` and `summary.sig` files to be cached at a
higher layer (for example, flatpak) between related pull operations (for
example, within a single flatpak transaction). This avoids
re-downloading `summary.sig` multiple times throughout a transaction,
which increases the transaction’s latency and introduces the possibility
for inconsistency between parts of the transaction if the server changes
its `summary` file part-way through.
In particular, this should speed up flatpak transactions on machines
with high latency network connections, where network round trips have a
high impact on the latency of an overall operation.

This is useful for ostree log on client side where often not the
full history of a branch is available. It is also helpful for
ostree show to show if a particular commit has a parent.
- Use `REV` instead of `REF` in places where we meant it.
- Fix `commit --parent` actually taking a commit checksum and not a ref.
- Fix `ostree admin switch` using `REF` instead of `REFSPEC`.
We use a similar trick to having a `sysroot -> .` symlink on the real root
here to support both /boot on root as well as on a separate filesystem. No
matter how it's mounted `/boot/xyz` will always refer to the file you'd
expect.
This is nicer than my previous attempts at this because there's no
configuration nor auto-detection required.
The "new style" code generally avoids `goto err` because it conflicts
with `__attribute__((cleanup))`. This fixes a compiler warning.

If `glnx_make_lock_file` falls back to `flock`, on NFS this uses POSIX
locks (`F_SETLK`). As such, we need to be able to handle `EACCES` as
well as `EAGAIN` (see `fnctl(2)`).
I think this is what coreos-ostree-importer has been hitting, which runs
on RHEL7 in the Fedora infra and does locking over an NFS share where
multiple apps could concurrently pull things into the repo.
This came in with 5af403be0c but
was never implemented.
I noticed this now because the Rust ostree bindings generate a
wrapper for it which the linker tries to use.
