| What's New In python-apt 1.0 | |
| ============================== | |
| Python-Apt 1.0 fixes several issues and use of deprecated methods. Most | |
| importantly, it introduces large file support | |
| New features | |
| ------------ | |
| * :class:`apt_pkg.AcquireFile` can now take a hash string that is not an | |
| md5 value, using the new `hash` argument. | |
| * A new a :meth:`apt_pkg.TagFile.close` method was added | |
| * :class:`apt_pkg.TagFile` is now a context manager | |
| * The high-level cache class, :class:`apt.cache.Cache` and it's companion | |
| :class:`apt.cache.FilteredCache` now support package | |
| names with special architecture qualifiers such as :all and :native. | |
| * The method :meth:`apt.cache.Cache.connect2` allows connecting callbacks on | |
| cache changes that take the cache as their first argument, reducing the | |
| potential for reference cycles. | |
| * The property :attr:`apt.package.Version.is_installed` was added. | |
| * The properties :attr:`apt.package.BaseDependency.installed_target_versions` | |
| and :attr:`apt.package.Dependency.installed_target_versions` were added. | |
| * The property :class:`apt.Dependency.rawtype` was added to give the raw type | |
| of a dependency, such as 'Depends'. | |
| * The attribute :attr:`apt_pkg.Dependency.comp_type_deb` and the property | |
| :attr:`apt.Dependency.relation_deb` were added, they return a Debian-style | |
| comparison operator instead of a mathematical-style one. | |
| * A new filter for filtered caches is provided, :class:`apt.cache.InstalledFilter`. | |
| Backward-incompatible changes | |
| ----------------------------- | |
| * :class:`apt.Version` now compares package names in addition to version only | |
| when checking for equality. This was broken previously. | |
| Deprecated | |
| ---------- | |
| The following features are deprecated, starting with this release: | |
| * The `section` member of :class:`apt_pkg.Package` | |
| * The `files` member of of :class:`apt_pkg.SourceRecords` | |
| * The `md5` argument to :class:`apt_pkg.AcquireFile`, it is replaced by | |
| the `hash` argument. | |
| * The method :meth:`apt.cache.Cache.connect` has been deprecated. It is | |
| replaced by :meth:`apt.cache.Cache.connect2` which is more flexible and | |
| less prone to reference cycles. | |
| * The attribute :attr:`apt_pkg.AcquireItem.mode` has been replaced by | |
| :attr:`apt_pkg.AcquireItem.active_subprocess` | |
| * The class :class:`apt_pkg.IndexRecords` has been deprecated and will | |
| be removed in the next release. | |
| Removed | |
| ------- | |
| * The module :mod:`apt.progress.gtk2` has been removed. There were no | |
| users in the Debian archive, its last update was in 2013, and it was buggy | |
| already. Apart from that, it suggested that it is OK to run a graphical | |
| application as root, and used the unmaintained GTK+ 2 version. | |
| Therefore, there is no replacement, please use PackageKit or aptdaemon | |
| for installation in graphical environments. | |
| * The attribute :attr:`apt_pkg.Package.auto` was not set anymore, and thus | |
| removed. | |
| Maintenance | |
| ----------- | |
| * The classes :class:`apt.cache.Cache` and :class:`apt.cache.FilteredCache` no | |
| longer store cyclic references to/between them. This fixes a huge issue, | |
| because a cache can have tens of open file descriptors, causing the maximum | |
| of file descriptors to be reached easily. | |
| * :mod:`apt_inst` now supports ar and tar archives that are larger than 4 GiB | |
| * Various smaller bug fixes | |
