Release notes
Open source →Added
umoci repacknow supports--refresh-bundlewhich will update the OCI bundle's metadata (mtree and umoci-specific manifests) after packing the image tag. This means that the bundle can be used as a base layer for future diffs without needing to unpack the image again. opencontainers/umoci#196- Added a website, and reworked the documentation to be better structured. You
can visit the website at
umo.ci. opencontainers/umoci#188 - Added support for the
user.rootlesscontainersspecification, which allows for persistent on-disk emulation ofchown(2)inside rootless containers. This implementation is interoperable with @AkihiroSuda'sPRootfork (though we do not test its interoperability at the moment) as both tools use the same protobuf specification. opencontainers/umoci#227 umoci unpacknow has support for opaque whiteouts (whiteouts which remove all children of a directory in the lower layer), thoughumoci repackdoes not currently have support for generating them. While this is technically a spec requirement, through testing we've never encountered an actual user of these whiteouts. opencontainers/umoci#224 opencontainers/umoci#229umoci unpackwill now use some rootless tricks inside user namespaces for operations that are known to fail (such asmknod(2)) while other operations will be carried out as normal (such aslchown(2)). It should be noted that the/proc/self/uid_mapchecking we do can be tricked into not detecting user namespaces, but you would need to be trying to break it on purpose. opencontainers/umoci#171 opencontainers/umoci#230
Fixed
- Fix a bug in our "parent directory restore" code, which is responsible for ensuring that the mtime and other similar properties of a directory are not modified by extraction inside said directory. The bug would manifest as xattrs not being restored properly in certain edge-cases (which we incidentally hit in a test-case). opencontainers/umoci#161 opencontainers/umoci#162
umoci unpackwill now "clean up" the bundle generated if an error occurs during unpacking. Previously this didn't happen, which made cleaning up the responsibility of the caller (which was quite difficult if you were unprivileged). This is a breaking change, but is in the error path so it's not critical. opencontainers/umoci#174 opencontainers/umoci#187umoci gcnow will no longer remove unknown files and directories that aren'tflock(2)ed, thus ensuring that any possible OCI image-spec extensions or other users of an image being operated on will no longer break. opencontainers/umoci#198umoci unpack --rootlesswill now correctly handle regular file unpacking when overwriting a file thatumocidoesn't have write access to. In addition, the semantics of pre-existing hardlinks to a clobbered file are clarified (the hard-links will not refer to the new layer's inode). opencontainers/umoci#222 opencontainers/umoci#223
