The backend should not convert partial lines to full log lines. While
this works for most cases it cannot work when the last line is partial
since it will just be lost. The frontend logic can already display
partial lines correctly. The journald driver also works correctly since
it does not such conversion.

The test calls podman run -d followed by podman logs. There is no
guarantee the the container or conmon has written all its output.
Adding an extra podman wait should fix this.
Do not remove the -d to not print 1000 unnecessary lines in the logs.

The following problems regarding `logs --tail` with the journald log
driver are fixed:
- One more line than a specified value is displayed.
- '--tail 0' displays all lines while the other log drivers displays
nothing.
- Partial lines are not considered.
- If the journald events backend is used and a container has exited,
nothing is displayed.
Integration tests that should have detected the bugs are also fixed. The
tests are executed with json-file log driver three times without this
fix.

e2e test failures are rife with messages like:
Expected 1 to equal 0
These make me cry. They're anti-helpful, requiring the reader
to dive into the source code to figure out what those numbers
mean.
Solution: Go tests have a '.Should(Exit(NNN))' mechanism. I
don't know if it spits out a better diagnostic (I have no way
to run e2e tests on my laptop), but I have to fantasize that
it will, and given the state of our flakes I assume that at
least one test will fail and give me the opportunity to see
what the error message looks like.
THIS IS NOT REVIEWABLE CODE. There is no way for a human
to review it. Don't bother. Maybe look at a few random
ones for sanity. If you want to really review, here is
a reproducer of what I did:
cd test/e2e
! positive assertions. The second is the same as the first,
! with the addition of (unnecessary) parentheses because
! some invocations were written that way. The third is BeZero().
perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(Equal\((\d+)\)\)/Expect($1).Should(Exit($2))/' *_test.go
perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(\(Equal\((\d+)\)\)\)/Expect($1).Should(Exit($2))/' *_test.go
perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(BeZero\(\)\)/Expect($1).Should(Exit(0))/' *_test.go
! Same as above, but handles three non-numeric exit codes
! in run_exit_test.go
perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(Equal\((\S+)\)\)/Expect($1).Should(Exit($2))/' *_test.go
! negative assertions. Difference is the spelling of 'To(Not)',
! 'ToNot', and 'NotTo'. I assume those are all the same.
perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.To\(Not\(Equal\((0)\)\)\)/Expect($1).To(ExitWithError())/' *_test.go
perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.ToNot\(Equal\((0)\)\)/Expect($1).To(ExitWithError())/' *_test.go
perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.NotTo\(Equal\((0)\)\)/Expect($1).To(ExitWithError())/' *_test.go
! negative, old use of BeZero()
perl -pi -e 's/Expect\((\S+)\.ExitCode\(\)\)\.ToNot\(BeZero\(\)\)/Expect($1).Should(ExitWithError())/' *_test.go
Run those on a clean copy of main branch (at the same branch
point as my PR, of course), then diff against a checked-out
copy of my PR. There should be no differences. Then all you
have to review is that my replacements above are sane.
UPDATE: nope, that's not enough, you also need to add gomega/gexec
to the files that don't have it:
perl -pi -e '$_ .= "$1/gexec\"\n" if m!^(.*/onsi/gomega)"!' $(grep -L gomega/gexec $(git log -1 --stat | awk '$1 ~ /test\/e2e\// { print $1}'))
UPDATE 2: hand-edit run_volume_test.go
UPDATE 3: sigh, add WaitWithDefaultTimeout() to a couple of places
UPDATE 4: skip a test due to bug #10935 (race condition)

Fix a race in the k8s-file logs driver. When "following" the logs,
Podman will print the container's logs until the end. Previously,
Podman logged until the state transitioned into something non-running
which opened up a race with the container still running, possibly in
the "stopping" state.
To fix the race, log until we've seen the wait event for the specific
container. In that case, conmon will have finished writing all logs to
the file, and Podman will read it until EOF.
Further tweak the integration tests for testing `logs -f` on a running
container. Previously, the test only checked for one of two lines
stating that there was a race. Indeed the race was in using `run --rm`
where a log file may be removed before we could fully read it.

Fix a race in journald driver. Following the logs implies streaming
until the container is dead. Streaming happened in one goroutine,
waiting for the container to exit/die and signaling that event happened
in another goroutine.
The nature of having two goroutines running simultaneously is pretty
much the core of the race condition. When the streaming goroutines
received the signal that the container has exitted, the routine may not
have read and written all of the container's logs.
Fix this race by reading both, the logs and the events, of the container
and stop streaming when the died/exited event has been read. The died
event is guaranteed to be after all logs in the journal which guarantees
not only consistencty but also a deterministic behavior.
Note that the journald log driver now requires the journald event
backend to be set.

With the advent of Podman 2.0.0 we crossed the magical barrier of go
modules. While we were able to continue importing all packages inside
of the project, the project could not be vendored anymore from the
outside.
Move the go module to new major version and change all imports to
`github.com/containers/libpod/v2`. The renaming of the imports
was done via `gomove` [1].

This incorporates code from PR #6591 and #6614 but does not use
event channels to detect container state and rather uses timers
with a defined wait duration before calling t.StopAtEOF() to
ensure the last log entry is output before a container exits.
The polling interval is set to 250 milliseconds based on polling
interval defined in hpcloud/tail here:

When the container uses journald logging, we don't want to
automatically use the same driver for its exec sessions. If we do
we will pollute the journal (particularly in the case of
healthchecks) with large amounts of undesired logs. Instead,
force exec sessions logs to file for now; we can add a log-driver
flag later (we'll probably want to add a `podman logs` command
that reads exec session logs at the same time).
As part of this, add support for the new 'none' logs driver in
Conmon. It will be the default log driver for exec sessions, and
can be optionally selected for containers.
Great thanks to Joe Gooch (mrwizard@dok.org) for adding support
to Conmon for a null log driver, and wiring it in here.

Test has been flaking excessively. A quick look shows that
the test itself is broken, making a bad assumption.
'podman logs -f' is guaranteed to exit when a container
terminates. This does not (and should not) mean that the
container has been cleaned up. It is undefined and unsafe
to run 'podman run -n same-name-as-terminated-container'
immediately after 'podman logs' exits.
Solution: instead of 'podman run', do 'podman inspect'.
This, too, is unsafe, but we can expect to see one of
two possible conditions:
1) command succeeds, in which case we require that
container State.Status be "exited"; or
2) command fails, in which case we expect "no such
container" in error output
For full coverage we should add a small delay-check test
to (1) to ensure that the container is cleaned up after
a short amount of time. Leaving that as a TODO because
it's more than my Go skills can handle, and I want to
get this checked in ASAP to get rid of the flake hassle.
