**podman compose** is a thin wrapper around an external compose provider
such as docker-compose or podman-compose. This means that `podman
compose` is executing another tool that implements the compose
functionality but sets up the environment in a way to let the compose
provider communicate transparently with the local Podman socket. The
specified options as well the command and argument are passed directly
to the compose provider.
The default compose providers are `docker-compose` and `podman-compose`.
If installed, `docker-compose` takes precedence since it is the original
implementation of the Compose specification and is widely used on the
supported platforms (i.e., Linux, Mac OS, Windows).
If you want to change the default behavior or have a custom installation
path for your provider of choice, please change the `compose_provider`
field in `containers.conf(5)`. You may also set the
`PODMAN_COMPOSE_PROVIDER` environment variable.

`podman system service` + TCP is not a configuration we should be
recommending. There was already language about this in the
manpages, but it was not sufficient in explaining how bad of an
idea this is. Expand the manpage warnings, add a dedicated
heading so people notice, and add a warning every time the
service starts with a TCP URL that directs people to the manpage
to see that explanation.

Some quadlet tests are failing on RHEL8: test code was
using journalctl to check output from containers. This
fails on RHEL8, where default log driver is k8s-file.
Solution: use 'podman logs' instead. To do so, we need to
keep the containers alive (otherwise, quadlet seems to
delete them on exit). Do so by running 'top -b' (batch);
the currently-used 'top' was failing because not-a-tty.

When I reworked pod removal to provide more detailed errors
(including per-container errors, not just a single multierror
with all errors squashed), I made it part of the struct returned
by the REST API and assumed that would be enough to get errors
through to clients. Unfortunately, in case of an overarching
error removing the pod (as any error with any container would
cause), we don't send the response struct that would include the
container errors - we just send a standardized REST error. We
could work around this with custom, potentially backwards
incompatible error handling for the REST pod delete endpoint, or
we could just do what was done before, and package up all the
errors in a multierror to send to the other side. Of those
options, the multierror seems far simpler.

Adds a `--no-trunc` flag to `podman kube generate` preventing the
annotations from being trimmed at 63 characters. However, due to
the fact the annotations will not be trimmed, any annotation that is
longer than 63 characters means this YAML will no longer be Kubernetes
compatible. However, these YAML files can still be used with `podman
kube play` due to the addition of the new flag below.

This commit extends `Volume` and `Network` unit definitions with two
additional parameters, `VolumeName` and `NetworkName`, which will,
respectively, set a user-defined name for the corresponding volume and
network. This is similar to how the `ContainerName` directive currently
works, and should allow for smoother transitions to Quadlet-managed

Previous tests have worked by pure chance since the client and server
ran on the same host; the server picked up the credentials created by
the client login.
Extend the gating tests and add a new integration test which is further
capable of exercising the remote code.

The podman-login tests have accumulated much cruft over the
years, because that's the only place where we run a local
registry, and the process was crufty: we actually start/stopped
the registry as the first & last tests of the file. Meaning,
you couldn't do 'hack/bats 150:just-one-test' because that
would skip the registry start. And just now, a completely
unrelated test has had to be shoved into the login file.
This PR revamps the whole thing, by adding a new registry helper
module that can be used anywhere. And, once the registry is
started, it just stays running until the end of tests. (This
requires BATS 1.7 or greater).

This reverts commit c2a24abc0d, which
itself reverted 1c08f2edac, which
reverted e33f4e0bc7.
The original e33f4e0bc7 "pasta: Use two connections instead of three
in TCP range forward tests" was a workaround to avoid intermittent
errors in CI where the pasta networking port range forwarding tests
would fail. It was reverted and unreverted when we thought we'd fixed
the problem, but that turned out not to be the case.
We're now much more confident that we've genuinely found and fixed (or
at least, worked around) the underlying problem, so we revert it again.

With a number of the port range forwarding tests, we've seen occasional
failures where the sending socat fails with an EINTR on connect(). This
was mitigated by e33f4e0bc7 "pasta: Use two connections instead of three
in TCP range forward tests" (which has been reverted and un-reverted
several times). However, this did not eliminate the problem, for example
see [0].
For the failing tests we are using the socat address "EXEC:printf x" to
make socat invoke printf(1) to generate a single byte of data to transfer.
Closer analysis shows that the SIGCHLD as the printf process ends is
occasionally intersecting with the connect() call causing this failure.
This is arguably a bug in socat, to not handle this race one way or
another. However, we can easily workaround the problem by using a
temporary file with the data to transfer, rather than invoking printf every
time. Do this, to avoid the flakiness of these tests.

https://github.com/containers/podman/pull/19021 fixed bugs with the pasta
networking tests not working on hosts with multiple interfaces. Alas, the
patch left in some stale code that generates spurious error messages for
the IPv6 case. This is sort of harmless - later code overrides what's done
here and the tests can pass anyway. However if a test fails for some other
reason it means we get a misleading irrelevant error message.

At various points the pasta bats tests need to know the name of the
interface that pasta will use by default, and the host addresses it will
use by default. Currently we use the pre-existing helper functions
ether_get_name and ipv[46]_get_addr_global to retreive that.
However, those just pick the first non-loopback interface or address, which
may not be the one that pasta uses if there are multiple connected host
interfaces.
Replace those helpers with local ones which examine the routing table to
more closely match pasta's internal logic about which interface to select.
This allows the tests to run successfully on a host with multiple
interfaces.

Add new _prefetch helper for fetching and caching images.
Use it in a few places, most importantly 120-load.bats
where our teardown() now runs 'rmi -af'.
Reason: in #17911 we discovered that podman save + load do
not actually preserve the image: annotations and other metadata
are lost. This means that a test which runs after 120-load.bats
is operating on a different $IMAGE than a test which runs before.
This is not a problem except in very obscure corner cases, like
one fixed in #18542, but it seems irresponsible to just handwave
that issue away
The _prefetch function uses skopeo for fetching and saving
images, because skopeo preserves digests and metadata.
[Side note for posterity: I tried amending basic_setup() to
always rmi -a + prefetch, instead of the current images -a +
rmi unwanted ones. That slowed down system tests by 10 minutes,
presumably because loads are much slower than queries. I reverted
that change and am documenting it as a reminder of why we do things
the way we do.]

Commit f131eaa74a changed restart to a stop+start motivated by
comments in the systemd man pages that restart behaves different than
stop+start, for instance, that it keeps certain resources open and
treats timers differently. Yet, the actually fix for #17607 in the very
same commit was dealing with an ENOENT of the CID file on container
removal.
As it turns out in in #18926, changing to stop+start regressed on
restarting dependencies when auto updating a systemd unit. Hence, move
back to using restart to make sure that dependent systemd units are
restarted as well.
An alternative could be recommending to use `BindsTo=` in Quadlet files
but this seems less common than `Requires=` and hence more risky to
cause issues on user sites.
