APIs for extracting OSTree commits from container images

Structs

ImporterMode 🔒

Constants

MAX_METADATA_SIZE 🔒

Limit on metadata objects (dirtree/dirmeta); this is copied from ostree-core.h. TODO: Bind this in introspection

Upper size limit for “small” regular files.

Functions

entry_to_variant 🔒

Given a tar entry, read it all into a GVariant

header_attrs 🔒

import_tar

Read the contents of a tarball and import the ostree commit inside. Returns the sha256 of the imported commit.

import_tar_objects

Read the contents of a tarball and import the content objects inside. Generates a synthetic commit object referencing them.

objtype_from_string 🔒

parse_checksum 🔒

parse_object_entry_path 🔒

Parse an object path into (parent, rest, objtype).

parse_xattrs_link_target 🔒

Parse a .file-xattrs-link link target into the corresponding checksum.

validate_metadata_header 🔒

Validate size/type of a tar header for OSTree metadata object.

validate_sha256 🔒
