What’s New In python-apt 1.7¶

Changed¶

Starting with 1.6.1 and 1.7~alpha1, the exception raised when passing objects of a different cache to apt_pkg.DepCache is apt_pkg.CacheMismatchError, and apt.cache.Cache will automatically remap open packages and versions to a new cache.
apt_pkg.Policy.get_priority() now accepts apt_pkg.Version objects in addition to apt_pkg.Package and apt_pkg.PackageFile ones.
apt.package.Version.policy_priority now returns the priority for that version rather than the highest priority for one of its package files.
apt.Cache.commit() and apt_pkg.DepCache.commit() now use frontend locking to run dpkg.

The class apt_pkg.PackageRecords can now lookup custom fields using records[key] and key in records.
All code is now statically typed. Some methods from apt_pkg and apt_inst might still be missing or more strict than necessary.
A new method apt.cache.Cache.fix_broken() has been added.
New methods for frontend locking have been added: apt_pkg.pkgsystem_lock_inner(), apt_pkg.pkgsystem_unlock_inner(), apt_pkg.pkgsystem_is_locked() (starting in alpha 3).
