repository: remove storedeltachains from ifilestorage
The ifilestorage interface was bootstrapped from requirements of
callers outside the storage implementation (revlogs). I believe we
even made some members public so they could be part of the interface!
Historically, the changegroup code was a gross offender when it
came to accessing low-level storage primitives. There are a handful
of members on the ifilestorage interface that are/were used only
for changegroup code.
With the recent refactor of changegroup code and the establishment
of a formal API on the storage interface for producing revision
deltas, the changegroup code is no longer accessing these low-level
primitives related to delta generation directly. Instead, things
are abstracted away in the storage implementation.
This means we can remove elements from the storage interface that
are no longer needed.
We start with "storedeltachains."
We remove it from the interface. Then we make it a private
attribute and update all references.
.. api:: storedeltachains has been dropped from ifilestorage interface
.. api:: storedeltachains on revlog classes is now _storedeltachains

Mercurial has the ability to add new features through the use of extensions. Extensions may add new commands, add options to existing commands, change the default behavior of commands, or implement hooks. To enable the "foo" extension, either shipped with Mercurial or in the Python search path, create an entry for it in your configuration file, like this:: [extensions] foo = You may also specify the full path to an extension:: [extensions] myfeature = ~/.hgext/myfeature.py See :hg:`help config` for more information on configuration files. Extensions are not loaded by default for a variety of reasons: they can increase startup overhead; they may be meant for advanced usage only; they may provide potentially dangerous abilities (such as letting you destroy or modify history); they might not be ready for prime time; or they may alter some usual behaviors of stock Mercurial. It is thus up to the user to activate extensions as needed. To explicitly disable an extension enabled in a configuration file of broader scope, prepend its path with !:: [extensions] # disabling extension bar residing in /path/to/extension/bar.py bar = !/path/to/extension/bar.py # ditto, but no path was supplied for extension baz baz = !
