Internal support for handling deprecations in Djblets.

The version-specific objects in this module are not considered stable between releases, and may be removed at any point. The base objects are considered stable.

exception BaseRemovedInDjbletsVersionWarning[source]

Bases: exceptions.DeprecationWarning

Base class for a Djblets deprecation warning.

All version-specific deprecation warnings inherit from this, allowing callers to check for Djblets deprecations without being tied to a specific version.

exception RemovedInDjblets20Warning[source]

Bases: djblets.deprecation.BaseRemovedInDjbletsVersionWarning

Deprecations for features removed in Djblets 2.0.

Note that this class will itself be removed in Djblets 2.0. If you need to check against Djblets deprecation warnings, please see BaseRemovedInDjbletsVersionWarning. Alternatively, you can use the alias for this class, RemovedInNextDjbletsVersionWarning.


An alias for the next release of Djblets where features would be removed.
