* pkg/copy: introduce a CopierValentin Rothberg2020-12-09
| | | | | | | Introduce a `Copier` object to separate the copy-rule enforcement from copying. That allows for a better error reporting of the REST API. Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
* archive: move stat-header handling into copy packageValentin Rothberg2020-12-09
| | | | | | | | Move handling the stat header into `pkg/copy`. All copy-related should ideally be located in this package to increase locality and reduce scattering where possible. Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
* pkg/copy: add parsing APIValentin Rothberg2020-12-09
| | | | | | | | Add an API for parsing user input into a possibly specified container and path. This allows for sharing the parsing code between the local and the remote client (and bindings) in the future. Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
* 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>
