1345d0358b system tests: the catch-up game
- run test: minor cleanup to .containerenv test. Basically,
  make it do only two podman-runs (they're expensive) and
  tighten up the results checks

- ps test: add ps -a --storage. Requires small tweak to
  run_podman helper, so we can have "timeout" be an expected
  result

- sdnotify test: workaround for #8718 (seeing MAINPID=xxx as
  last output line instead of READY=1). As found by the
  newly-added debugging echos, what we are seeing is:

      MAINPID=103530
      READY=1
      MAINPID=103530

  It's not supposed to be that way; it's supposed to be just
  the first two. But when faced with reality, we must bend
  to accommodate it, so let's accept READY=1 anywhere in
  the output stream, not just as the last line.

f5b3dc976c Tests: Fix common flakes, and improve apiv2 test log
- 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.

1646da834c System test additions
- run --userns=keep-id: confirm that $HOME gets set (#8013)

 - inspect: confirm that JSON output is a sane number of
   lines (10 or more), not an unreadable one-liner (#8011
   and #8021). Do so with image, pod, network, volume
   because the code paths might be different.

 - cgroups: confirm that 'run' preserves cgroup manager (#7970)

 - sdnotify: reenable tests, and hope CI doesn't hang. This
   test was disabled on August 18 because CI jobs were hanging
   and timing out. My suspicion was that it was #7316, which
   in turn seems to have hinged on conmon #182. The latter
   was merged on Sep 16, so let's cross our fingers and see
   what happens.

Also: remove inaccurate warning from a networking test.

And, wow, fix is_cgroupsv2(), it has never actually worked.

a9dbd2b3de Migrate away from docker.io
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.

d254fa4c35 system tests: enable more remote tests; cleanup
info, images, run, networking tests: remove some skip_if_remote()s
that were added in the varlink days. All of these tests now seem
to work with APIv2.

help test: check that first output line from 'podman --help'
is the program description (regression check for #7273).

load test: clean up stray images, rewrite test to make it conform
to existing convention. In the process, discover and file #7337

exec test (and networking): file #7360, and add FIXME comment
to skip()s suggesting evaluating those tests once that is fixed.

pod test: now that #6328 is fixed, use 'podman pod inspect --format'
instead of relying on jq

Various other tests: add an explanation of why test is disabled
so we can more easily distinguish "this will never be meaningful
under remote" vs "hey, doesn't work for now, but maybe someday".

18f36d8cf6 Re-disable sdnotify tests to try to fix CI
Some CI tests are hanging, timing out in 60 or 120 minutes.
I wonder if it's #7316, the bug where all podman commands
hang forever if NOTIFY_SOCKET is set?

60ab5f3ae6 system tests: enable sdnotify tests
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.
