The intention of this change is to enable an option to increase swift
performance without changing any of the swift internals. This change is
in-line with documentation published by the good folks at swiftstack and
intel. This change will only effect swift when its installed in a
virtual environment which is a self-imposed limitation such that we're
not messing with the system's default Python.
New Options:
- A new option `swift_pypy_enabled` has been added to enable or
disable the pypy interpreter for swift. The default is "false".
- A new option `swift_pypy_archive` has been added to allow a
pre-built pypy archive to be downloaded and moved into place. This
option is a dictionary and contains the URL and SHA256 as keys.

features:
|
|
- While default python interpreter for swift is cpython, pypy is
|
|
now an option. This change adds the ability to greatly improve swift
|
|
performance without the core code modifications. These changes have
|
|
been implemented using the documentation provided by Intel and
|
|
Swiftstack. Notes about the performance increase can be seen
|
|
`here <https://software.intel.com/en-us/blogs/2016/05/06/doubling-the-performance-of-openstack-swift-with-no-code-changes>`_.
