(Sorry, couldn't resist).
CI flakes have been coming down - thank you to everyone who has
been making them a priority.
This leaves a noisy subset that I've just been ignoring for months:
Running: podman ... -p 8080:something
...cannot listen on the TCP port: listen tcp4 :8080: bind: address already in use
Sometimes these are one-time errors resolved on 2nd try; sometimes
they fail three times, forcing CI user to hit Rerun. In all cases
they make noise in my flake logs, which costs me time.
My assumption is that this has to do with ginkgo running random
tests in parallel. Since many e2e tests simplemindedly use 8080,
collisions are inevitable.
Solution: simplemindedly replace 8080 with other (also arbitrarily
picked) numbers. This is imperfect -- it requires human developers
to pick a number NNNN and 'grep NNNN test/e2e/*' before adding
new tests, which I am 100% confident ain't gonna happen -- but
it's better than what we have now.
Side note: I considered writing and using a RandomAvailablePort()
helper, but that would still be racy. Plus, it would be a pain
to interpolate strings into so many places. Finally, with this
hand-tooled approach, if/when we _do_ get conflicts on port NNNN,
it should be very easy to grep for NNNN, find the offending tests
that reuse that port, and fix one of them.

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)

We missed bumping the go module, so let's do it now :)
* Automated go code with github.com/sirkon/go-imports-rename
* Manually via `vgrep podman/v2` the rest

- When one or more containers in the Pod reports an error on an operation
report StatusConflict and report the error(s)
- jsoniter type encoding used to marshal error as string using error.Error()
- Update test framework to allow setting any flag when creating pods
- Fix test_resize() result check
Fixes#8865

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].

Add an `--infra-conmon-pidfile` flag to `podman-pod-create` to write the
infra container's conmon process ID to a specified path. Several
container sub-commands already support `--conmon-pidfile` which is
especially helpful to allow for systemd to access and track the conmon
processes. This allows for easily tracking the conmon process of a
pod's infra container.

Support the `--pod-id-file` flag in the rm, start and stop pod commands.
This completes the already support flag in pod-create and is another
prerequisite for generating generic systemd unit files for pods.
Also add completions, docs and tests.

when doing localized tests (not varlink), we can use secondary image
stores as read-only image caches. this cuts down on test time
significantly because each test does not need to restore the images from
a tarball anymore.

Add the ability to run the integration (ginkgo) suite using
the remote client.
Only the images_test.go file is run right now; all the rest are
isolated with a // +build !remotelinux. As more content is
developed for the remote client, we can unblock the files and
just block single tests as needed.

A pause container is added to the pod if the user opts in. The default pause image and command can be overridden. Pause containers are ignored in ps unless the -a option is present. Pod inspect and pod ps show shared namespaces and pause container. A pause container can't be removed with podman rm, and a pod can be removed if it only has a pause container.

Because our tests are getting so long, we want to be able to audit which tests are taking
the longest to complete. This may indicate a bad test, bad CI, bad code, etc and therefore
should be auditable.
Also, make speed improvements to tests by making sure we only unpack caches images that
actually get used.

As well as added tests, man pages, and completions.
Also reformatted and refactored a couple of other small things in the other pod commands.
