Helper to test WSGI applications
Werkzeug started as simple collection of various utilities for WSGI applications and has become one of the most advanced WSGI utility modules. It includes a powerful debugger, full featured request and response objects, HTTP utilities to handle entity tags, cache control headers, HTTP dates, cookie handling, file uploads, a powerful URL routing system and a bunch of community contributed addon modules. Werkzeug is unicode aware and doesn't enforce a specific template engine, database adapter or anything else. It doesn't even enforce a specific way of handling requests and leaves all that up to the developer. It's most useful for end user applications which should work on as many server environments as possible (such as blogs, wikis, bulletin boards, etc.). Details and example applications are available on the Werkzeug website <http://werkzeug.pocoo.org/>.
ZooKeeper python binding library
Alembic is a new database migrations tool, written by the author of `SQLAlchemy <http://www.sqlalchemy.org>`_. A migrations tool offers the following functionality: * Can emit ALTER statements to a database in order to change the structure of tables and other constructs * Provides a system whereby "migration scripts" may be constructed; each script indicates a particular series of steps that can "upgrade" a target database to a new version, and optionally a series of steps that can "downgrade" similarly, doing the same steps in reverse. * Allows the scripts to execute in some sequential manner.
This is a fork of amqplib which was originally written by Barry Pederson. It is maintained by the Celery project, and used by kombu as a pure python alternative when librabbitmq is not available. This library should be API compatible with librabbitmq. Differences from amqplib * Supports draining events from multiple channels (Connection.drain_events) * Support for timeouts * Channels are restored after channel error, instead of having to close the connection. * Support for heartbeats o Connection.heartbeat_tick(rate=2) must called at regular intervals (half of the heartbeat value if rate is 2). o Or some other scheme by using Connection.send_heartbeat. * Supports RabbitMQ extensions: o Consumer Cancel Notifications + by default a cancel results in ChannelError being raised + but not if a on_cancel callback is passed to basic_consume. o Publisher confirms + Channel.confirm_select() enables publisher confirms. + Channel.events['basic_ack'].append(my_callback) adds a callback to be called when a message is confirmed. This callback is then called with the signature (delivery_tag, multiple). o Exchange-to-exchange bindings: exchange_bind / exchange_unbind. + Channel.confirm_select() enables publisher confirms. + Channel.events['basic_ack'].append(my_callback) adds a callback to be called when a message is confirmed. This callback is then called with the signature (delivery_tag, multiple). * Support for basic_return * Uses AMQP 0-9-1 instead of 0-8. o Channel.access_request and ticket arguments to methods removed. o Supports the arguments argument to basic_consume. o internal argument to exchange_declare removed. o auto_delete argument to exchange_declare deprecated o insist argument to Connection removed. o Channel.alerts has been removed. o Support for Channel.basic_recover_async. o Channel.basic_recover deprecated. * Exceptions renamed to have idiomatic names: o AMQPException -> AMQPError o AMQPConnectionException -> ConnectionError`` o AMQPChannelException -> ChannelError`` o Connection.known_hosts removed. o Connection no longer supports redirects. o exchange argument to queue_bind can now be empty to use the "default exchange". * Adds Connection.is_alive that tries to detect whether the connection can still be used. * Adds Connection.connection_errors and .channel_errors, a list of recoverable errors. * Exposes the underlying socket as Connection.sock. * Adds Channel.no_ack_consumers to keep track of consumer tags that set the no_ack flag. * Slightly better at error recovery
Client library for AMQP (Advanced Message Queuing Protocol) Supports the 0-8 AMQP spec, and has been tested with RabbitMQ and Python's 2.4, 2.5, and 2.6.
Anyjson loads whichever is the fastest JSON module installed and provides a uniform API regardless of which JSON implementation is used.
Babel is composed of two major parts: * tools to build and work with gettext message catalogs * a Python interface to the CLDR (Common Locale Data Repository), providing access to various locale display names, localized number and date formatting, etc.
Beaker is a caching library that includes Session and Cache objects built on Myghty's Container API used in MyghtyUtils. WSGI middleware is also included to manage Session objects and signed cookies.
Boto is a Python package that provides interfaces to Amazon Web Services. It supports over thirty services, such as S3 (Simple Storage Service), SQS (Simple Queue Service), and EC2 (Elastic Compute Cloud) via their REST and Query APIs. The goal of boto is to support the full breadth and depth of Amazon Web Services. In addition, boto provides support for other public services such as Google Storage in addition to private cloud systems like Eucalyptus, OpenStack and Open Nebula.
