Running functional tests in the in-process mode uses the default value for proxy-server object_post_as_copy, which is True. This patch adds support for an environment variable to change this value to False so that the fast-post mode is tested when running in-process functional tests. The patch also adds a new tox environment func-in-process-fast-post which forces in-process functional testing with object_post_as_copy=False. The motivation for this change, apart from enabling configurable local testing, is to put support in place for an upstream CI job that will actually functionally test the fast-post mode, which is otherwise only covered by unit tests. There are currently two gate jobs that run the functional tests: - gate-swift-dsvm-functional runs the tests *twice* against a devstack swift service, once using tempauth and once using keystoneauth. The devstack swift service uses the default object_post_as_copy=True. - gate-swift-tox-func runs the func tests in in-process mode which also uses tempauth and object_post_as_copy=True. This duplicates one of the config scenarios above. With this change either the gate-swift-tox-func job or a new job could run the functional tests using object_post_as_copy=False.

Swift
A distributed object storage system designed to scale from a single machine to thousands of servers. Swift is optimized for multi-tenancy and high concurrency. Swift is ideal for backups, web and mobile content, and any other unstructured data that can grow without bound.
Swift provides a simple, REST-based API fully documented at http://docs.openstack.org/.
Swift was originally developed as the basis for Rackspace's Cloud Files and was open-sourced in 2010 as part of the OpenStack project. It has since grown to include contributions from many companies and has spawned a thriving ecosystem of 3rd party tools. Swift's contributors are listed in the AUTHORS file.
Docs
To build documentation install sphinx (pip install sphinx), run
python setup.py build_sphinx, and then browse to /doc/build/html/index.html.
These docs are auto-generated after every commit and available online at
http://docs.openstack.org/developer/swift/.
For Developers
The best place to get started is the "SAIO - Swift All In One". This document will walk you through setting up a development cluster of Swift in a VM. The SAIO environment is ideal for running small-scale tests against swift and trying out new features and bug fixes.
You can run unit tests with .unittests and functional tests with
.functests.

Code Organization
- bin/: Executable scripts that are the processes run by the deployer
- doc/: Documentation
- etc/: Sample config files
- swift/: Core code
- account/: account server

- proxy/: proxy server
- test/: Unit and functional tests
Data Flow
Swift is a WSGI application and uses eventlet's WSGI server. After the
processes are running, the entry point for new requests is the Application
class in swift/proxy/server.py. From there, a controller is chosen, and the
request is processed. The proxy may choose to forward the request to a back-
end server. For example, the entry point for requests to the object server is
the ObjectController class in swift/obj/server.py.
For Deployers
Deployer docs are also available at http://docs.openstack.org/developer/swift/. A good starting point is at http://docs.openstack.org/developer/swift/deployment_guide.html
You can run functional tests against a swift cluster with .functests. These
functional tests require /etc/swift/test.conf to run. A sample config file
can be found in this source tree in test/sample.conf.
For Client Apps
For client applications, official Python language bindings are provided at http://github.com/openstack/python-swiftclient.
