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)

When attempting to copy files into and out of running containers
within the host pidnamespace, the code was attempting to join the
host pidns again, and getting an error. This was causing the podman
cp command to fail. Since we are already in the host pid namespace,
we should not be attempting to join. This PR adds a check to see if
the container is in NOT host pid namespace, and only then attempts to
join.

Ignore permission errors when copying from a rootless container.
TTY devices inside rootless containers are owned by the host's
root user which is "nobody" inside the container's user namespace
rendering us unable to even read them.

users.

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.

Implement `podman-remote cp` and break out the logic from the previously
added `pkg/copy` into it's basic building blocks and move them up into
the `ContainerEngine` interface and `cmd/podman`.
The `--pause` and `--extract` flags are now deprecated and turned into
nops.
Note that this commit is vendoring a non-release version of Buildah to
pull in updates to the copier package.

* Add a new `pkg/copy` to centralize all container-copy related code.
* The new code is based on Buildah's `copier` package.
* The compat `/archive` endpoints use the new `copy` package.
* Update docs and an several new tests.
* Includes many fixes, most notably, the look-up of volumes and mounts.
Breaking changes:
* Podman is now expecting that container-destination paths exist.
Before, Podman created the paths if needed. Docker does not do
that and I believe Podman should not either as it's a recipe for
masking errors. These errors may be user induced (e.g., a path
typo), or internal typos (e.g., when the destination may be a
mistakenly unmounted volume). Let's keep the magic low for such
a security sensitive feature.

Now that Dan has added helpful comments to each SkipIfRemote,
let's take the next step and include those messages in the
Skip() output so someone viewing test results can easily
see if a remote test is skipped for a real reason or for
a FIXME.
This commit is the result of a simple:

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].

podman-remote has not been tested. A principal part of the
problem was #5387 - the YAML I wrote did not have the
intended effect, it did not set TEST_REMOTE_CLIENT=true
and because of my multiple iterations I did not catch this
during testing.
Part 1 of this PR is to fix .cirrus.yml to enable remote tests.
Part 2 -- what I had first noticed and tried to fix -- is that
rootless_test.sh was never running remote because, of course,
envariables are not sent via ssh. I reworked integration_test.sh
and rootless_test.sh to use a command-line decision instead.
Part 3, sigh, is to disable one failing integration test
and *all* system tests, because so many of the latter are
failing. Addressing those failures needs to be done in
subsequent PRs. Issues #6538, #6539, #6540 are filed for
some of the problems I isolated. There will be more.
Also, minor, fixed some stale references to varlink.

`podman cp` used to copy the contents under the source directory to the destination. But according to the specification in podman-cp.md. it should copy the whole directory to the destination if the destination directory already exists.
- src dir ends with /., copy the contents to dest dir
- src dir does not end with /.
- dest dir /home does not exist, copy the contents
- dest dir /home exists, copy the directory
