* | support multi-image (docker) archivesValentin Rothberg2020-09-08
|/ | | | | | | | | | | | | Support loading and saving tarballs with more than one image. Add a new `/libpod/images/export` endpoint to the rest API to allow for exporting/saving multiple images into an archive. Note that a non-release version of containers/image is vendored. A release version must be vendored before cutting a new Podman release. We force the containers/image version via a replace in the go.mod file; this way go won't try to match the versions.

* fix panic when checking len on nil objectBrent Baude2020-08-28
| | | | | | issue #7444 describes a problem where an image does not have a manifest file and cannot be processed by our library correctly. the origin of the panic is because we are checking the len of a nil object's attribute. this is a temporary fix to protect from the panic in the future. the origin of the problem is more interesting and requires more work when the code author returns from pto.

| * image list: speed upValentin Rothberg2020-08-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Listing images has shown increasing performance penalties with an increasing number of images. Unless `--all` is specified, Podman will filter intermediate images. Determining intermediate images has been done by finding (and comparing!) parent images which is expensive. We had to query the storage many times which turned it into a bottleneck. Instead, create a layer tree and assign one or more images to nodes that match the images' top layer. Determining the children of an image is now exponentially faster as we already know the child images from the layer graph and the images using the same top layer, which may also be considered child images based on their history. On my system with 510 images, a rootful image list drops from 6 secs down to 0.3 secs. Also use the tree to compute parent nodes, and to filter intermediate images for pruning.

* Add podman image mountDaniel J Walsh2020-07-28
| | | | | | | | | | | | | There are many use cases where you want to just mount an image without creating a container on it. For example you might want to just examine the content in an image after you pull it for security analysys. Or you might want to just use the executables on the image without running it in a container. The image is mounted readonly since we do not want people changing images.

* 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].
