In fixing https://github.com/coreos/rpm-ostree/pull/3323
I felt that it was a bit ugly we're installing `/usr/bin/ostree-container`.
It's kind of an implementation detail. We want users to use
`ostree container`.
Let's support values outside of $PATH too.
For example, this also ensures that TAB completion for `ost` expands
to `ostree ` with a space.
This removes a 'g_setenv()' call, which could potentially be unsafe
in a multi-thread context.
The current libselinux codebase does not seem to check for
`LIBSELINUX_DISABLE_PCRE_PRECOMPILED`, so I think this has no effects
nowadays.
Additionally, I could not find any reference to it in libselinux
git history, so I'm not sure if it ever played any role at all.
My current understanding is that this is coming from version
incompatibilities between an older libselinux in the build environment
and a newer policy (with precompiled regexs) in the target.
But from the ML discussion I found, I think it eventually got
solved in a different way, possibly by avoiding the policy binary
caches.

This swaps the order of a couple of input sanity checks, in order
to fix a minor memory leak due to an early-return on the error
path.
Memory for the result is now allocated only after input has been
sanity-checked.
It fixes a static analysis warning highlighted by Coverity.
This adds build-time configuration logic to automatically detect
and switch between libfuse 2.x and 3.x.

Fixes `Argument with 'nonnull' attribute passed null` by making
the code not exist at all anymore.
In upstream libsoup this code is gone too; it uses `GUri` from glib
which we probably could now too, but one thing at a time.
This adds some logic to detect and dispatch unknown subcommands to
extensions available in `$PATH`. Additional commands can be
implemented by adding relevant `ostree-$verb` binaries to the system.
As an example, if a `/usr/bin/ostree-extcommand` extension is provided,
the execution of `ostree extcommand --help` will be dispatched to that
as `ostree-extcommand extcommand --help`.
This is trying to address:
https://pagure.io/fedora-iot/issue/48
Basically we changed rpm-ostree to start doing a shared lock during
commit by default, but this broke because pungi is starting a process
doing a commit for each architecture, and then trying to regenerate
the summary after each one.
This patch is deleting a big comment with a rationale for why
summary regeneration should be exclusive. Point by point:
> This makes sure the commits and deltas don't get
> deleted while generating the summary.
But prune operations require an exclusive lock, which means that
data still can't be deleted when the summary grabs a shared lock.
> It also means we can be sure refs
> won't be created/updated/deleted during the operation, without having to
> add exclusive locks to those operations which would prevent concurrent
> commits from working.
First: The status quo *has* prevented concurrent commits from working!
There is no real locking solution to this problem. What we really
need to do here is regenerate the summary after each commit *or*
when the caller decides to do it and e.g. include deltas at the same
time.
It's OK if multiple threads race to regenerate the summary;
last-one-wins behavior here is totally fine.
We should only try to remount `/sysroot` if we're actually handling the
sysroot repo and the repo isn't writable. We already have public APIs to
check each of those, so let's use them.
Closes: #2485
This moves read-only sysroot checks upfront, so that they are not
intermixed with mount operations.
It has no immediate side-effects, but allow these check to be
independent from the rest of the mounting logic (and future changes
to it).
This adds a `MS_SILENT` flag to all `mount(2)` calls, reducing the
amount of kernel logs produced on each boot.
Those messages do not contain actionable details, and in the "mount
plus read-only remount" case they can easily become highly redundant.
In general, we're probably going to need to change most of our
`g_return_if_fail` to `g_assert`. The analyzer flags that
the function can return `NULL`, but the caller isn't prepared for
this.
In practice, let's abort.

This defines `OstreeRepoAutoTransaction` as a boxed type, in order
to support auto-generating bindings for it.
That first requires adding internal reference-counting to it, to
allow freely copying/freeing references to a single transaction guard.
This rewords errors and log messages in the functions which take care
of preparing sysroot in initramfs.
Depending on the boot flow, it is possible to reach this logic
with a sysroot mounted (unexpectedly) as read-only.
In that case, let's clearly point out the problematic mountpoint.
This enhances the auto-transaction logic, augmenting the scope of a
transaction guard.
It allows committing or aborting a transaction through its guard.
It also supports tracking the completion status of a transaction
guard, avoiding double commits/aborts, while retaining the auto-cleanup
logic.
