When nocopy is specified, the files from the container image are not

avoid any I/O operation on the volume if the source directory is empty.
This is useful on network file systems (since CAP_DAC_OVERRIDE is not
honored) where the root user might not have enough privileges to
perform an I/O operation on the NFS mount but the user running inside
the container has.

currently, setting any sort of resource limit in a pod does nothing. With the newly refactored creation process in c/common, podman ca now set resources at a pod level
meaning that resource related flags can now be exposed to podman pod create.
cgroupfs and systemd are both supported with varying completion. cgroupfs is a much simpler process and one that is virtually complete for all resource types, the flags now just need to be added. systemd on the other hand
has to be handeled via the dbus api meaning that the limits need to be passed as recognized properties to systemd. The properties added so far are the ones that podman pod create supports as well as `cpuset-mems` as this will
be the next flag I work on.

This bug was introduced in https://github.com/containers/podman/pull/8906.
When we use 'podman rm/restart/stop/kill etc...' command to
the container running with --rm, the OCI runtime directory
remains at /run/<runtime name> (root user) or
/run/user/<user id>/<runtime name> (rootless user).
This bug could cause other bugs.
For example, when we checkpoint the container running with
--rm (podman checkpoint --export) and restore it
(podman restore --import) with crun, error message
"Error: OCI runtime error: crun: container `<container id>`
already exists" is outputted.
This error is caused by an attempt to restore the container with
the same container ID as the remaining OCI runtime's container ID.
Therefore, I fix that the cleanupRuntime() function runs to
remove the OCI runtime directory,
even if the container has already been removed by --rm option.

Since it may be a while before we get a true fix: add a
workaround for podman-remote checkpoint tests, in which
we pause until the 'run --rm' container is truly truly gone.
I've tried to make it as easy as possible to clean up
the workaround code once the bug is fixed.
Oh, also, remove "-it" from a podman-run. It makes no sense
and only results in nasty orange warning messages.

Libpod requires that all volumes are stored in the libpod db. Because
volume plugins can be created outside of podman, it will not show all
available plugins. This podman volume reload command allows users to
sync the libpod db with their external volume plugins. All new volumes
from the plugin are also created in the libpod db and when a volume from
the db no longer exists it will be removed if possible.
There are some problems:
- naming conflicts, in this case we only use the first volume we found.
This is not deterministic.
- race conditions, we have no control over the volume plugins. It is
possible that the volumes changed while we run this command.

Add 4 new subcommands to the testvol binary, instead of just serving the
volume api it now also can create/list/remove plugins. This is required
to test new functionality where volumes are create outside of podman in
the plugin. Podman should then be able to pick up the new volumes.
The new testvol commands are:
- serve: serve the podman api like the the testvol command before
- create: create a volume with the given name
- list: list all volume names
- remove: remove the volume with the given name
Also make a small update to the testvol Containerfile so that it can
build correctly.

I think it is confusion to have this Containerfile in the repo root. It
is used for the tests only so we should move it into the same dir.
Also adapt the Makefile target to use the new path and add the current

Firstly: don't prune exit codes after a refresh - instead, clear
the table entirely. We are guaranteed that all containers are
gone after a refresh, we should not worry about exit codes given
this.
Secondly: alter the way pruning was done. We were updating the DB
by calling Update from within an existing View, and stacking an
RW transaction on top of an existing RO one seems dodgy; further,
modifying a bucket while iterating over it with ForEach is
undefined behavior.
Hopefully this will resolve our CI issues.

This commit addresses three intertwined bugs to fix an issue when using
Gitlab runner on Podman. The three bug fixes are not split into
separate commits as tests won't pass otherwise; avoidable noise when
bisecting future issues.
1) Podman conflated states: even when asking to wait for the `exited`
state, Podman returned as soon as a container transitioned to
`stopped`. The issues surfaced in Gitlab tests to fail [1] as
`conmon`'s buffers have not (yet) been emptied when attaching to a
container right after a wait. The race window was extremely narrow,
and I only managed to reproduce with the Gitlab runner [1] unit
tests.
2) The clearer separation between `exited` and `stopped` revealed a race
condition predating the changes. If a container is configured for
autoremoval (e.g., via `run --rm`), the "run" process competes with
the "cleanup" process running in the background. The window of the
race condition was sufficiently large that the "cleanup" process has
already removed the container and storage before the "run" process
could read the exit code and hence waited indefinitely.
Address the exit-code race condition by recording exit codes in the
main libpod database. Exit codes can now be read from a database.
When waiting for a container to exit, Podman first waits for the
container to transition to `exited` and will then query the database
for its exit code. Outdated exit codes are pruned during cleanup
(i.e., non-performance critical) and when refreshing the database
after a reboot. An exit code is considered outdated when it is older
than 5 minutes.
While the race condition predates this change, the waiting process
has apparently always been fast enough in catching the exit code due
to issue 1): `exited` and `stopped` were conflated. The waiting
process hence caught the exit code after the container transitioned
to `stopped` but before it `exited` and got removed.
3) With 1) and 2), Podman is now waiting for a container to properly
transition to the `exited` state. Some tests did not pass after 1)
and 2) which revealed the third bug: `conmon` was executed with its
working directory pointing to the OCI runtime bundle of the
container. The changed working directory broke resolving relative
paths in the "cleanup" process. The "cleanup" process error'ed
before actually cleaning up the container and waiting "main" process
ran indefinitely - or until hitting a timeout. Fix the issue by
executing `conmon` with the same working directory as Podman.
Note that fixing 3) *may* address a number of issues we have seen in the
past where for *some* reason cleanup processes did not fire.

One day we may use AWS for part of CI. Do you want to maintain
two separate code paths in this script for linking to artifacts
in multiple cloud providers? Can you say no? I knew you could.
Cirrus already knows the location of the artifacts and provides
a transparent mechanism for accessing them. Use it.
This PR exposed a nasty bug in our environment-variable handling:
envariables passed through to the containerized environment were
being double-space-escaped, so "FOO=a b" ended up as "FOO=a\ b"
(with a backslash), with one consequence being invalid URLs.
The solution is simple: run 'podman -e FOO', not '-e FOO=value'.
Finally, reinstate the environment-variable dump (in comments).
I had removed this in a moment of panic over leaking secrets,
but no, that doesn't happen. Exclude scary-sounding vars anyway.
