From 0f7d54b0260c1be992ee3b9cee359ef3a9e8bd21 Mon Sep 17 00:00:00 2001 From: Valentin Rothberg Date: Thu, 22 Apr 2021 08:01:12 +0200 Subject: migrate Podman to containers/common/libimage Migrate the Podman code base over to `common/libimage` which replaces `libpod/image` and a lot of glue code entirely. Note that I tried to leave bread crumbs for changed tests. Miscellaneous changes: * Some errors yield different messages which required to alter some tests. * I fixed some pre-existing issues in the code. Others were marked as `//TODO`s to prevent the PR from exploding. * The `NamesHistory` of an image is returned as is from the storage. Previously, we did some filtering which I think is undesirable. Instead we should return the data as stored in the storage. * Touched handlers use the ABI interfaces where possible. * Local image resolution: previously Podman would match "foo" on "myfoo". This behaviour has been changed and Podman will now only match on repository boundaries such that "foo" would match "my/foo" but not "myfoo". I consider the old behaviour to be a bug, at the very least an exotic corner case. * Futhermore, "foo:none" does *not* resolve to a local image "foo" without tag anymore. It's a hill I am (almost) willing to die on. * `image prune` prints the IDs of pruned images. Previously, in some cases, the names were printed instead. The API clearly states ID, so we should stick to it. * Compat endpoint image removal with _force_ deletes the entire not only the specified tag.
