We now no longer write containers.conf, instead system connections and
farms are written to a new file called podman-connections.conf.
This is a major rework and I had to change a lot of things to get this
to compile again with my c/common changes.
It is a breaking change for users as connections/farms added before this
commit can now no longer be removed or modified directly. However because
the logic keeps reading from containers.conf the old connections can
still be used to connect to a remote host.

Back when we introduced ExitCleanly(), we couldn't use it
on Debian because of too many runc bugs. Now, early 2024:
- #11784 has been closed-wontfix, so add a runc special-case
in the specific test that triggers it.
- #11785 seems to have gone away? Treat it as fixed.
- #19552 is languishing, so let's just close-wontfix it too and
add another runc special case.
- and, one new rootless-cgroupsV1 exception for a warning msg
that snuck in recently.

New VMs have netavark 1.9, which fixes the "cannot talk to syslog"
warning when running containerized, so we can reenable clean-output
checks in containerized e2e tests
pasta: some new VMs have passt >= 2023-11-10, but f38 does not,
and f39 is unclear (my version extractor could not tell). So
I'm leaving the 20170 skip.
Debian runc now supports umask in *run*, but not *exec*. Even
with runc 1.1.10. And we don't even know what the situation is
on RHEL... so, run the podman-run umask tests but not exec.

1. toolbox UID/GID allocation: pick numbers < 1500. Otherwise
we run the risk of colliding with the Cirrus rootless user.
2. WaitContainerReady(): check the results of the last "podman logs"
before timing out. Otherwise, the user will see "READY" followed
immediately by "Container is not ready".
(global bug, not just toolbox, but that's where I discovered it).

Directly writing to stdout/err is not safe when run in parallel.
Ginkgo v2 fixed this buffering the output and syncing the output so it
is not mangled between tests.
This means we should use the GinkgoWriter everywhere to make sure the
output stays in sync.

I found the ginkgolinter[1] by accident, this looks for not optimal
matching and suggest how to do it better.
Overall these fixes seem to be all correct and they will give much
better error messages when something fails.

Package `io/ioutil` was deprecated in golang 1.16, preventing podman from
building under Fedora 37. Fortunately, functionality identical
replacements are provided by the packages `io` and `os`. Replace all
usage of all `io/ioutil` symbols with appropriate substitutions
according to the golang docs.

... primarily so that it can support OCI artifacts.
2.8 already seems to exist in the repo.
This requires changing WaitContainerReady to also check
stderr (ultimately because docker/distribution was
updated to a more recent sirupsen/logrus, which logs
by default to stderr instead of stdout).

I honestly do not understand all this extra option parsing here but
there is really no reason to exclude the option for remote, all the
other global options are also set there.
This fixes a problem with mixed cni/netavark use because the option was
unset.

...and enable the at-test-time confirmation, the one that
double-checks that if CI requests runc we actually use runc.
This exposed a nasty surprise in our setup: there are steps to
define $OCI_RUNTIME, but that's actually a total fakeout!
OCI_RUNTIME is used only in e2e tests, it has no effect
whatsoever on actual podman itself as invoked via command
line such as in system tests. Solution: use containers.conf
Given how fragile all this runtime stuff is, I've also added
new tests (e2e and system) that will check $CI_DESIRED_RUNTIME.
Image source: https://github.com/containers/automation_images/pull/146
Since we haven't actually been testing with runc, we need
to fix a few tests:
- handle an error-message change (make it work in both crun and runc)
- skip one system test, "survive service stop", that doesn't
work with runc and I don't think we care.
...and skip a bunch, filing issues for each:
- #15013 pod create --share-parent
- #15014 timeout in dd
- #15015 checkpoint tests time out under $CONTAINER
- #15017 networking timeout with registry
- #15018 restore --pod gripes about missing --pod
- #15025 run --uidmap broken
- #15027 pod inspect cgrouppath broken
- ...and a bunch more ("podman pause") that probably don't
even merit filing an issue.
Also, use /dev/urandom in one test (was: /dev/random) because
the test is timing out and /dev/urandom does not block. (But
the test is still timing out anyway, even with this change)
Also, as part of the VM switch we are now using go 1.18 (up
from 1.17) and this broke the gitlab tests. Thanks to @Luap99
for a quick fix.
Also, slight tweak to #15021: include the timeout value, and
reword message so command string is at end.
Also, fixed a misspelling in a test name.

The errcheck linter makes sure that errors are always check and not
ignored by accident. It spotted a lot of unchecked errors, mostly in the
tests but also some real problem in the code.
Signed-off-by: Paul Holzinger <pholzing@redhat.com>
The linter ensures a common code style.
- use switch/case instead of else if
- use if instead of switch/case for single case statement
- add space between comment and text
- detect the use of defer with os.Exit()
- use short form var += "..." instead of var = var + "..."
- detect problems with append()
```
newSlice := append(orgSlice, val)
```
This could lead to nasty bugs because the orgSlice will be changed in
place if it has enough capacity too hold the new elements. Thus we
newSlice might not be a copy.
Of course most of the changes are just cosmetic and do not cause any
logic errors but I think it is a good idea to enforce a common style.
This should help maintainability.

golint, scopelint and interfacer are deprecated. golint is replaced by
revive. This linter is better because it will also check for our error
style: `error strings should not be capitalized or end with punctuation or a newline`
scopelint is replaced by exportloopref (already endabled)
interfacer has no replacement but I do not think this linter is
important.

When this option was added to the e2e tests, there was no CI Automation
support for running remote tests w/ netavark. When added, many
e2e test errors/failures are generated due to this option not being
valid for the remote client. Fix this in the tests by conditionally
adding the option if the test is running the remote client.

Add a proof of concept for benchmarking Podman. The benchmarks are
implemented by means of the end-to-end test suite but hidden behind
a `benchmarks` build tag. Running `make localbenchmarks` will run
`test/e2e` with the specific build tag and set ginkgo's "focus" to
the specific "Podman Benchmark Suite" to only run this spec and skip
all others.
ginkgo will print a report before terminating listing the CPU and memory
stats for each benchmark. New benchmarks can easily be added via the
`newBenchmark` function that also supports adding an `init()` function
to each benchmark which allows for performing certain setups for the
specific benchmark. For instance, benchmarking `podman start` requires
creating a container beforehand.
Podman may be called more than once in the main function of a benchmark
but note that the displayed memory consumption is then a sum of all
Podman invocations. The memory consumption is collected via
`/usr/bin/time`.
A benchmark's report is split into CPU and memory as displayed below:
```
[CPU] podman images:
Fastest Time: 0.146s
Slowest Time: 0.187s
Average Time: 0.180s ± 0.015s
[MEM] podman images:
Smallest: 41892.0KB
Largest: 42792.0KB
Average: 42380.7KB ± 286.4KB
```
Note that the benchmarks are not wired into the CI yet. They are meant
as a proof of concept. More benchmarks and the plumbing into CI will
happen in a later change.

- It probably doesn't actually make a difference: in experiments,
the github.com/containers/storage/pkg/stringid RNG initialization
has been happening later
- This makes the RNG caller-controlled (which we don't benefit from),
but also the same on all nodes of multi-process Ginkgo execution.
So, if it works at all, it may make collisions of random ID values
more likely, and our tests are not robust against that. So don't
go out of our way to make collisions more likely.
