* Fix problems reported by staticcheckPaul Holzinger2021-01-12
| | | | | | | | | | | | | | `staticcheck` is a golang code analysis tool. https://staticcheck.io/ This commit fixes a lot of problems found in our code. Common problems are: - unnecessary use of fmt.Sprintf - duplicated imports with different names - unnecessary check that a key exists before a delete call There are still a lot of reported problems in the test files but I have not looked at those.

|\ | | | | Add support for checkpoint/restore of containers with volumes
| * Include named volumes in container migrationRadostin Stoyanov2021-01-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When migrating a container with associated volumes, the content of these volumes should be made available on the destination machine. This patch enables container checkpoint/restore with named volumes by including the content of volumes in checkpoint file. On restore, volumes associated with container are created and their content is restored. The --ignore-volumes option is introduced to disable this feature. Example: # podman container checkpoint --export checkpoint.tar.gz <container> The content of all volumes associated with the container are included in `checkpoint.tar.gz` # podman container checkpoint --export checkpoint.tar.gz --ignore-volumes <container> The content of volumes is not included in `checkpoint.tar.gz`. This is useful, for example, when the checkpoint/restore is performed on the same machine. # podman container restore --import checkpoint.tar.gz The associated volumes will be created and their content will be restored. Podman will exit with an error if volumes with the same name already exist on the system or the content of volumes is not included in checkpoint.tar.gz # podman container restore --ignore-volumes --import checkpoint.tar.gz Volumes associated with container must already exist. Podman will not create them or restore their content. Signed-off-by: Radostin Stoyanov <rstoyanov@fedoraproject.org>

Reclaimed space from volumes, images, and containers is recorded during the prune call in a PruneReport struct. These structs are collected into a slice during a system prune and processed afterwards to calculate the total reclaimed space. Closes #8658 Signed-off-by: Baron Lenardson <lenardson.baron@gmail.com>

This could cause errors in `podman inspect` or similar on the container, as the definition of its OCI spec has been changed by the exec session. The change never propagates to the DB, so it's limited to a single process, but we should still avoid it when possible - so deep-copy it before use. Signed-off-by: Matthew Heon <mheon@redhat.com>
