* podman cp: support copying on tmpfs mountsValentin Rothberg2021-03-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

* remote copyValentin Rothberg2020-12-18
| | | | | | | | | | | | | | 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.

* rewrite podman-cpValentin Rothberg2020-12-04
| | | | | | | | | | | | | | | | | | | | | | | | * 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. Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

* e2e tests: SkipIfRemote(): add a reasonEd Santiago2020-09-23
| | | | | | | | | | | | | | | | | 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: perl -pi -e 's;(SkipIfRemote)\(\)(\s+//\s+(.*))?;$1("$3");' *.go in the test/e2e directory, with a few minor (manual) changes in wording.

* move go module to v2Valentin Rothberg2020-07-06
| | | | | | | | | | | | | | | 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].

* | WIP: Enable (and disable) remote testingEd Santiago2020-06-09
|/ | | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Ed Santiago <santiago@redhat.com>
