Rework the --network parse logic to support multiple networks with
specific network configuration settings.
--network can now be set multiple times. For bridge network mode the
following options have been added:
- **alias=name**: Add network-scoped alias for the container.
- **ip=IPv4**: Specify a static ipv4 address for this container.
- **ip=IPv6**: Specify a static ipv6 address for this container.
- **mac=MAC**: Specify a static mac address address for this container.
- **interface_name**: Specify a name for the created network interface inside the container.
So now you can set --network bridge:ip=10.88.0.10,mac=44:33:22:11:00:99
for the default bridge network as well as for network names.
This is better than using --ip because we can set the ip per network
without any confusion which network the ip address should be assigned
to.
The --ip, --mac-address and --network-alias options are still supported
but --ip or --mac-address can only be set when only one network is set.
This limitation already existed previously.
The ability to specify a custom network interface name is new

Podman adds a few environment variables by default, and

This option will allow you to specify which defaults you don't

There is a race where `conn.Close()` was called before `conn.CloseWrite()`.
In this case `CloseWrite` will fail and an useless error is printed. To
fix this we move the the `CloseWrite()` call to the same goroutine to
remove the race. This ensures that `CloseWrite()` is called before
`Close()` and never afterwards.
Also fixed podman-remote run where the STDIN was never was closed.
This is causing flakes in CI testing.

Fix day-one sloppiness: when I first wrote this framework
it compared strings using 'expr', not '=', to be more
forgiving of extra cruft in output. This was a bad decision.
It means that warnings or additional text are ignored:
is "all is ok, NOT!" "all is ok" <-- this would pass
Solution: tighten up the 'is' check. Use '=' (direct
compare) first. If it fails, look for wild cards ('*')
or character classes ('[') in the expect string. If
so, and only then, use 'expr'. And, thanks to a clever
suggestion from Luap99, include '(using expr)' in the
error message when we do so; this could make it easier
for a developer to understand a string mismatch.
This change exposes a lot of instances in which we weren't
doing proper comparisons. Fix those. Thankfully, there
weren't as many as I'd feared.
Also, and completely unrelated, add '-T' flag to bats
helper, for showing timing results. (I will open this
as a separate PR if requested. I too find it offensive

Migrate the Podman code base over to `common/libimage` which replaces
`libpod/image` and a lot of glue code entirely.
Note that I tried to leave bread crumbs for changed tests.
Miscellaneous changes:
* Some errors yield different messages which required to alter some
tests.
* I fixed some pre-existing issues in the code. Others were marked as
`//TODO`s to prevent the PR from exploding.
* The `NamesHistory` of an image is returned as is from the storage.
Previously, we did some filtering which I think is undesirable.
Instead we should return the data as stored in the storage.
* Touched handlers use the ABI interfaces where possible.
* Local image resolution: previously Podman would match "foo" on
"myfoo". This behaviour has been changed and Podman will now
only match on repository boundaries such that "foo" would match
"my/foo" but not "myfoo". I consider the old behaviour to be a
bug, at the very least an exotic corner case.
* Futhermore, "foo:none" does *not* resolve to a local image "foo"
without tag anymore. It's a hill I am (almost) willing to die on.
* `image prune` prints the IDs of pruned images. Previously, in some
cases, the names were printed instead. The API clearly states ID,
so we should stick to it.
* Compat endpoint image removal with _force_ deletes the entire not
only the specified tag.

When resolving the workdir of a container, we may need to create unless

A container's workdir can be specified via the CLI via `--workdir` and
via an image config with the CLI having precedence.
Since images have a tendency to specify workdirs without necessarily
shipping the paths with the root FS, make sure that Podman creates the
workdir. When specified via the CLI, do not create the path, but check
for its existence and return a human-friendly error.
NOTE: `crun` is performing a similar check that would yield exit code
127. With this change, however, Podman performs the check and yields
exit code 126. Since this is specific to `crun`, I do not consider it
to be a breaking change of Podman.

Followup to #8284, due to my not having noticed #8096.
RHEL gating tests are failing again due to rhbz#1895105, the
one where we can't run journalctl rootless on RHEL. #8284 fixed
this for some RHEL builds of older podman, but I missed #8096
which added yet another logs test.
This brings us to three journalctl exceptions, which means
it gets complicated because I have to refactor it all.
**THIS IS NOT SUSTAINABLE**. We need some way to have a similar
setup in CI, with a permission-less rootless login, so we don't
add yet another logs test some day and discover, months later,
that it doesn't work on RHEL and then have to go into crisis

The BATS 'run' directive is really quite obnoxious; for the

can more naturally be piggybacked into an rm test.

External containers are containers created outside of Podman.
For example Buildah and CRI-O Containers.
$ buildah from alpine
alpine-working-container
$ buildah run alpine-working-container touch /test
$ podman container exists --external alpine-working-container
$ podman container diff alpine-working-container
C /etc
A /test
Added --external flag to refer to external containers, rather then --storage.
Added --external for podman container exists and modified podman ps to use
--external rather then --storage. It was felt that --storage would confuse
the user into thinking about changing the storage driver or options.
--storage is still supported through the use of aliases.
Finally podman contianer diff, does not require the --external flag, since it
there is little change of users making the mistake, and would just be a pain
for the user to remember the flag.
podman container exists --external is required because it could fool scripts
that rely on the existance of a Podman container, and there is a potential
for a partial deletion of a container, which could mess up existing users.

Current these commands only check if a container exists in libpod. With
this fix, the commands will also check if they are in containers/storage.
This allows users to look at differences within a buildah or CRI-O container.
Currently buildah diff does not exists, so this helps out in that situation
as well as in CRI-O since the cri does not implement a diff command.
