The initial version of libimage changed the order of layers which has
now been restored to remain backwards compatible.
Further changes:
* Fix a bug in the journald logging which requires to strip trailing
new lines from the message. The system tests did not pass due to
empty new lines. Triggered by changing the default logger to
journald in containers/common.
* Fix another bug in the journald logging which embedded the container
ID inside the message rather than the specifid field. That surfaced
in a preceeding whitespace of each log line which broke the system
tests.
* Alter the system tests to make sure that the k8s-file and the
journald logging drivers are executed.
* A number of e2e tests have been changed to force the k8s-file driver
to make them pass when running inside a root container.
* Increase the timeout in a kill test which seems to take longer now.

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.

Instead of creating an extra container create a network and mount
namespace inside the podman user namespace. This ns is used to
for rootless cni operations.
This helps to align the rootless and rootful network code path.
If we run as rootless we just have to set up a extra net ns and
initialize slirp4netns in it. The ocicni lib will be called in
that net ns.
This design allows allows easier maintenance, no extra container
with pause processes, support for rootless cni with --uidmap
and possibly more.
The biggest problem is backwards compatibility. I don't think
live migration can be possible. If the user reboots or restart
all cni containers everything should work as expected again.
The user is left with the rootless-cni-infa container and image
but this can safely be removed.
To make the existing cni configs work we need execute the cni plugins
in a extra mount namespace. This ensures that we can safely mount over
/run and /var which have to be writeable for the cni plugins without
removing access to these files by the main podman process. One caveat
is that we need to keep the netns files at `XDG_RUNTIME_DIR/netns`
accessible.
`XDG_RUNTIME_DIR/rootless-cni/{run,var}` will be mounted to `/{run,var}`.
To ensure that we keep the netns directory we bind mount this relative
to the new root location, e.g. XDG_RUNTIME_DIR/rootless-cni/run/user/1000/netns
before we mount the run directory. The run directory is mounted recursive,
this makes the netns directory at the same path accessible as before.
This also allows iptables-legacy to work because /run/xtables.lock is
now writeable.

podman gating tests are hanging in the new Fedora CI setup;
long and tedious investigation suggests that 'socat' processes
are being left unkilled, which then causes BATS to hang when
it (presumably) runs a final 'wait' in its end cleanup.
The two principal changes are to exec socat in a subshell
with fd3 closed, and to pkill its child processes before
killing the process itself. I don't know if both are needed.
The pkill definitely is; the exec may just be superstition.
Since I've wasted more than a day of PTO time on this, I'm
okay with a little superstition. What I do know is that with
these two changes, my reproducer fails to reproduce in over
one hour of trying (normally it fails within 5 minutes).
AND, update: only rawhide (f35) leaves stray socat processes

Traditionally, the path resolution for containers has been resolved on
the *host*; relative to the container's mount point or relative to
specified bind mounts or volumes.
While this works nicely for non-running containers, it poses a problem
for running ones. In that case, certain kinds of mounts (e.g., tmpfs)
will not resolve correctly. A tmpfs is held in memory and hence cannot
be resolved relatively to the container's mount point. A copy operation
will succeed but the data will not show up inside the container.
To support these kinds of mounts, we need to join the *running*
container's mount namespace (and PID namespace) when copying.
Note that this change implies moving the copy and stat logic into
`libpod` since we need to keep the container locked to avoid race
conditions. The immediate benefit is that all logic is now inside
`libpod`; the code isn't scattered anymore.
Further note that Docker does not support copying to tmpfs mounts.
Tests have been extended to cover *both* path resolutions for running
and created containers. New tests have been added to exercise the
tmpfs-mount case.
For the record: Some tests could be improved by using `start -a` instead
of a start-exec sequence. Unfortunately, `start -a` is flaky in the CI
which forced me to use the more expensive start-exec option.

A container's workdir can be specified via the CLI via `--workdir` and

Since images have a tendency to specify workdirs without necessarily

for its existence and return a human-friendly error.
NOTE: `crun` is performing a similar check that would yield exit code

Podman defers stopping the container to the runtime, which can take some
time. Keeping the lock while waiting for the runtime to complete the
stop procedure, prevents other commands from acquiring the lock as shown
in #8501.
To improve the user experience, release the lock before invoking the
runtime, and re-acquire the lock when the runtime is finished. Also
introduce an intermediate "stopping" to properly distinguish from
"stopped" containers etc.

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
mode.

There exists a unit test to ensure that shell completion functions are
defined. However there was no check about the quality of the provided
shell completions. Lets change that.
The idea is to create a general test that makes sure we are suggesting
containers,pods,images... for the correct commands. This works by
reading the command use line and checking for each arg if we provide
the correct suggestions for this arg.
It includes the following tests:
- flag suggestions if [options] is set
- container, pod, image, network, volume, registry completion
- path completion for the appropriate arg KEYWORDS (`PATH`,`CONTEXT`,etc.)
- no completion if there are no args
- completion for more than one arg if it ends with `...]`
The test does not cover completion values for flags and not every arg KEYWORD
is supported. This is still a huge improvement and covers most use cases.
This test spotted several inconsistencies between the completion and the
command use line. All of them have been adjusted to make the test pass.
The biggest advantage is that the completions always match the latest
command changes. So if someone changes the arguments for a command this
ensures that the completions must be adjusted.

This adds a new command, 'podman network reload', to reload the
networks of existing containers, forcing recreation of firewall
rules after e.g. `firewall-cmd --reload` wipes them out.
Under the hood, this works by calling CNI to tear down the
existing network, then recreate it using identical settings. We
request that CNI preserve the old IP and MAC address in most
cases (where the container only had 1 IP/MAC), but there will be
some downtime inherent to the teardown/bring-up approach. The
architecture of CNI doesn't really make doing this without
downtime easy (or maybe even possible...).
At present, this only works for root Podman, and only locally.
I don't think there is much of a point to adding remote support
(this is very much a local debugging command), but I think adding
rootless support (to kill/recreate slirp4netns) could be
valuable.

- apiv2 - the 'ten /info requests' test is flaking often,
taking ~8 seconds (our limit is 7, up from 5 a few weeks
ago). Brent suggested that the first /info call might be
expensive, because it needs to access storage. So, let's
prime it by running one /info outside the timing loop.
And, because even that continues to fail, bump it up
to 10 seconds and file #8076 to track the slowdown.
- toolbox test - WaitForReady() has timed out, even on one
occasion causing a run failure because it failed 3 times.
Solution: bump up timeout from 2s to 5s. Not really great,
but CI systems are underpowered, and it's not unreasonable
that 2s might be too low.
- sdnotify test - add a 'podman wait' between stop & rm.
This may prevent a "cannot rm container as it is running"
race condition.
While working on this, Brent and I noticed a few ways that
test-apiv2 logging can be improved:
- test name: when request is POST, display the jsonified
parameters, not the original input ones. This should
make it much easier to reproduce failures.
- use curl's "--write-out" option to capture http code,
content type, and request time. We were getting the
first two via grep from logged headers; this is cleaner.
And there was no other way to get timing. We now include
the timing as X-Response-Time in the log file.
- abort on *any* curl error, not just 7 (cannot connect).
Any error at all from curl is bad news.

External containers are containers created outside of Podman.

$ 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.

Record the user-specified "raw" image name in the SpecGenerator, so we
can pass it along to the config when creating a container. We need a
separate field as the image name in the generator may be set to the
ID of the previously pulled image - ultimately the cause of #7404.
Reverting the image name from the ID to the user input would not work
since "alpine" for pulling iterates over the search registries in the
registries.conf but looking up "alpine" normalizes to
"localhost/alpine".
Recording the raw-image name directly in the generator was the best of
the options I considered as no hidden magic from search registries or
normalizations (that may or may not change in the future) can interfere.
The auto-update backend enforces that the raw-image name is a
fully-qualified reference, so we need to worry about that in the front
end.

CI and system tests currently pull some images from docker.io.
Eliminate that, by:
- building a custom image containing much of what we need
for testing; and
- copying other needed images to quay.io
(Reason: effective 2020-11-01 docker.io will limit the
number of image pulls).
The principal change is to create a new quay.io/libpod/testimage,
using the new test/system/build-testimage script, instead of
relying on quay.io/libpod/alpine_labels. We also switch to
using a hardcoded :YYYYMMDD tag, instead of :latest, in an
attempt to futureproof our CI. This image includes 'httpd'
from busybox-extras, which we use in our networking test
(previously we had to pull and run busybox from docker.io).
The testimage can and should be extended as needed for future
tests, e.g. adding test file content or other useful tools.
For the '--pull' tests which require actually pulling from
the registry, I've created an image with the same name but
tagged :00000000 so it will never be pulled by default.
Since this image is only used minimally, it's just busybox.
Unfortunately there remain two cases we cannot solve in
this tiny alpine-based image:
1) docker registry
2) systemd
For those, I've (manually) run:
podman pull [ docker.io/library/registry:2.7 | registry.fedoraproject.org/fedora:31 ]
podman tag !$ quay.io/...
podman push !$
...and amended the calling tests accordingly.
I've tried to make the the smallest reasonable diff, not the
smallest possible one. I hope it's a reasonable tradeoff.

The test that does 'adduser' in a keep-id container had a
really dumb bug: if the user running the test has UID 1000,
then podman itself (via keep-id) will add the "1000" passwd
entry, and the in-container "adduser" will allocate 1001,
making our test fail. This triggered in f31/f32 podman gating
tests, but (?!?) never in rawhide gating tests.
Solution: explicitly feed a UID to adduser. Make sure that
it's not the same as the UID of the current user.
Also (unrelated): fix a ridiculous "run mkdir || die". At
the time I wrote that I probably had no idea how BATS works.

Oops. PR #6693 (sdnotify) added tests, but they were disabled
due to broken crun on f31. I tried for three weeks to get a
magic CI:IMG PR to update crun on the CI VMs ... but in that
time I forgot to actually enable those new tests.
This PR removes a 'skip', replacing it with a check that systemd
is running plus one more to make sure our runtime is crun. It
looks like sdnotify just doesn't work on Ubuntu (it hangs), and
my guess is that it's a crun/runc issue.
I also changed the test image from fedora:latest to :31, because,
sigh, fedora:latest removed the systemd-notify tool.
WARNING WARNING WARNING: the symptom of a missing systemd-notify
is that podman will hang forever, not even stopped by the timeout
command in podman_run! (Filed: #7316). This means that if the
sdnotify-in-container test ever fails, the symptom will be that
Cirrus itself will time out (2 hours?). This is horrible. I
don't know what to do about it other than push for a fix for 7316.

In local Podman, the frontend interprets the error and exit code
given by the Exec API to determine the appropriate exit code to
set for Podman itself; special cases like a missing executable
receive special exit codes.
Exec for the remote API, however, has to do this inside Libpod
itself, as Libpod will be directly queried (via the Inspect API
for exec sessions) to get the exit code. This was done correctly
when the exec session started properly, but we did not properly
handle cases where the OCI runtime fails before the exec session
can properly start. Making two error returns that would otherwise
not set exit code actually do so should resolve the issue.

New functionality in hack/man-page-checker: start cross-
referencing the man page 'Synopsis' line against the
output of 'podman foo --help'. This is part 1, flag/option
consistency. Part 2 (arg consistency) is too big and will
have to wait for later.
flag/option consistency means: if 'podman foo --help'
includes the string '[flags]' in the Usage message,
make sure the man page includes '[*options*]' in its
Synopsis line, and vice-versa. This found several
inconsistencies, which I've fixed.
While doing this I realized that Cobra automatically
includes a 'Flags:' subsection in its --help output
for all subcommands that have defined flags. This
is great - it lets us cross-check against the
usage synopsis, and make sure that '[flags]' is
present or absent as needed, without fear of
human screwups. If a flag-less subcommand ever
gets extended with flags, but the developer forgets
to add '[flags]' and remove DisableFlagsInUseLine,
we now have a test that will catch that. (This,
too, caught two instances which I fixed).
I don't actually know if the new man-page-checker
functionality will work in CI: I vaguely recall that
it might run before 'make podman' does; and also
vaguely recall that some steps were taken to remedy
that.

Nothing we can check.
For all others, though, the ALL-CAPS part on the

generate N+1 args and run that command. We expect
a 125 exit status and a suitably helpful error message.

Reversion of one part of #6679: my handling of 'realpath'
would not work when $PODMAN is 'podman-remote --url etc'.
Trying to handle that case got unmaintainable; so instead
let's just force 'make {local,remote}system' to invoke

runs the tests with a manual 'bats' invocation, but I
think I'm the only one who ever does that.
Since podman path will now be very long in the logs,
add code to logformatter to abbreviate it like we do
for the ginkgo logs.
And, one thing that has bugged me for a long time:
in the error logs, show a different prompt ('#' vs '$')

When you open a FIFO for reading, but there's no writer, you hang.
This is just one of those obscure UNIXisms we all know but just
forget all too often.
My last PR was guilty of introducing such a condition; I caught
it by accident while testing other stuff. In short, the signal
container was doing 'echo DONE' as its last step, and we (BATS)
were reading the FIFO to check for it; but if the container
exited before we opened the FIFO for read, the open would hang.
This is not a hang that we can catch in the test: it would hang
the entire job forever. CI would presumably time out eventually,
but with no useful indication of the cause of the error.
Solution: use 'exec' to open the FIFO early and keep it open,
and use 'read -u FD' instead of 'read <$fifo': the former
reads from an open FD, the latter forces a new open() each time.
There is a shorter, more maintainable solution -- see #4755 -- but
that suffers from the same hanging problem in the (unlikely) case
where the signal-handling container exits, e.g. if signal handling
is broken in podman. The test would hang, with no helpful indicator.
Although this PR is a little more advanced scripting, I have
commented the relevant code well and believe the maintenance
cost is worth the risk of undebuggable hangs.
There is still a hang risk: if 'podman logs -f' fails and exits
immediately, the 'exec' will hang. I can't think of a non-racy
way to prevent that, and choose to live with that risk.
Tested by temporarily including 9 (SIGKILL) in the signals list.
The read timeout triggers, and the end user has a fair chance
of tracking down the root cause.

Rewrite so we can guarantee that, by creating a new image.
Also add slightly more helpful tests: the initial tests
would just show "expected 0, got 1" which is unhelpful.
Tweak so we test on actual history contents, which will
show more informative messages on failure.
And, finally, clean up after ourselves.

We leverage the containers/storage image history tracking feature to
show the previously used image names when running:
`podman images --history`

Unless specified otherwise by --all, --latest or via arguments, list all
running containers. This matches the behaviour of Docker and is also
illustrated in the man pages where containers and options are marked to
be optional.

podman exec leaks an exec_pid_<hash> file for every exec in tmpfs,
it's known rhbz#1731117, this case makes sure leakage issue has
been fixed.

When a container is created with a given OCI runtime, but then it
is uninstalled or removed from the configuration file, Libpod
presently reacts very poorly. The EvictContainer code can
potentially remove these containers, but we still can't see them
in `podman ps` (aside from the massive logrus.Errorf messages
they create).
Providing a minimal OCI runtime implementation for missing
runtimes allows us to behave better. We'll be able to retrieve
containers from the database, though we still pop up an error for
each missing runtime. For containers which are stopped, we can
remove them as normal.

...e.g. cloud-user. 9822f54ac was intended to fix this,
but it doesn't. Simple and standard solution is to
move the dash to the end of the character class.

On Ubuntu, /bin/sh != /bin/bash. Update system-tests to only use
bash for testing consistency across platforms.

Issue #3829 (cp symlinks) has been fixed: enable tests for it
And, it looks like podman-remote is now handling exit status
of a force-rm'ed container. Enable that test too.

This patch let podman cp return 'no such file or directory' error if DEST_PATH does not exist and ends with / when copying file.

Test had incorrectly been disabled for all podman; it
should've been disabled only for podman-remote. Fixed
that, and fixed the problem that was causing failures:
podman-remote is gobbling up stdin (#4095), so no
tests were actually being run at all, or only one.
Fixed by redirecting input on the run_podman invocation.
Added, as backup, a confirmation mechanism to ensure
that all expected tests are being run.
Note that test is reenabled, but the output check is
disabled for podman-remote due to #4096; this at least
lets us check exit status.

While investigating issue
https://github.com/containers/libpod/issues/4044 there is no sense
subjecting forward progress elsewhere. Skip the test with a note
temporarily, until a resolution to 4044 and any other related issues
is found and fix implemented.
