-=================================
- celery - Distributed Task Queue
-=================================
-
-.. image:: http://cloud.github.com/downloads/celery/celery/celery_128.png
-
-:Version: 3.1.26 (Cipater)
-:Web: http://celeryproject.org/
-:Download: http://pypi.python.org/pypi/celery/
-:Source: http://github.com/celery/celery/
-:Keywords: task queue, job queue, asynchronous, async, rabbitmq, amqp, redis,
-  python, webhooks, queue, distributed

-
-What is a Task Queue?
-=====================
-
-Task queues are used as a mechanism to distribute work across threads or
-machines.
-
-A task queue's input is a unit of work, called a task, dedicated worker
-processes then constantly monitor the queue for new work to perform.
-
-Celery communicates via messages, usually using a broker
-to mediate between clients and workers.  To initiate a task a client puts a
-message on the queue, the broker then delivers the message to a worker.
-
-A Celery system can consist of multiple workers and brokers, giving way
-to high availability and horizontal scaling.
-
-Celery is a library written in Python, but the protocol can be implemented in
-any language.  So far there's RCelery_ for the Ruby programming language, and a
-`PHP client`, but language interoperability can also be achieved
-by using webhooks.
-
-.. _RCelery: http://leapfrogdevelopment.github.com/rcelery/
-.. _`PHP client`: https://github.com/gjedeer/celery-php
-.. _`using webhooks`:
-    http://docs.celeryproject.org/en/latest/userguide/remote-tasks.html
-
-What do I need?
-===============
-
-Celery version 3.0 runs on,
-
-- Python (2.5, 2.6, 2.7, 3.2, 3.3)
-- PyPy (1.8, 1.9)
-- Jython (2.5, 2.7).
-
-This is the last version to support Python 2.5,
-and from Celery 3.1, Python 2.6 or later is required.
-The last version to support Python 2.4 was Celery series 2.2.
-
-*Celery* is usually used with a message broker to send and receive messages.
-The RabbitMQ, Redis transports are feature complete,
-but there's also experimental support for a myriad of other solutions, including
-using SQLite for local development.
-
-*Celery* can run on a single machine, on multiple machines, or even
-across datacenters.
-
-Get Started
-===========
-
-If this is the first time you're trying to use Celery, or you are
-new to Celery 3.0 coming from previous versions then you should read our
-getting started tutorials:
-
-- `First steps with Celery`_
-
-    Tutorial teaching you the bare minimum needed to get started with Celery.
-
-- `Next steps`_
-
-    A more complete overview, showing more features.
-
-.. _`First steps with Celery`:
-    http://docs.celeryproject.org/en/latest/getting-started/first-steps-with-celery.html
-
-.. _`Next steps`:
-    http://docs.celeryproject.org/en/latest/getting-started/next-steps.html
-
-Celery is...
-============
-
-- **Simple**
-
-    Celery is easy to use and maintain, and does *not need configuration files*.
-
-    It has an active, friendly community you can talk to for support,
-    including a `mailing-list`_ and and an IRC channel.
-
-    Here's one of the simplest applications you can make::
-
-        from celery import Celery
-
-        app = Celery('hello', broker='amqp://guest@localhost//')
-
-        @app.task
-        def hello():
-            return 'hello world'
-
-- **Highly Available**
-
-    Workers and clients will automatically retry in the event
-    of connection loss or failure, and some brokers support
-    HA in way of *Master/Master* or *Master/Slave* replication.
-
-- **Fast**
-
-    A single Celery process can process millions of tasks a minute,
-    with sub-millisecond round-trip latency (using RabbitMQ,
-    py-librabbitmq, and optimized settings).
-
-- **Flexible**
-
-    Almost every part of *Celery* can be extended or used on its own,
-    Custom pool implementations, serializers, compression schemes, logging,
-    schedulers, consumers, producers, autoscalers, broker transports and much more.
-
-It supports...
-==============
-
-    - **Message Transports**
-
-        - RabbitMQ_, Redis_,
-        - MongoDB_ (experimental), Amazon SQS (experimental),
-        - CouchDB_ (experimental), SQLAlchemy_ (experimental),
-        - Django ORM (experimental), `IronMQ`_
-        - and more...
-
-    - **Concurrency**
-
-        - Prefork, Eventlet_, gevent_, threads/single threaded
-
-    - **Result Stores**
-
-        - AMQP, Redis
-        - memcached, MongoDB
-        - SQLAlchemy, Django ORM
-        - Apache Cassandra, IronCache
-
-    - **Serialization**
-
-        - *pickle*, *json*, *yaml*, *msgpack*.
-        - *zlib*, *bzip2* compression.
-        - Cryptographic message signing.

-Framework Integration
-=====================
-
-Celery is easy to integrate with web frameworks, some of which even have
-integration packages:
-
-    +--------------------+------------------------+
-    | `Django`_          | not needed             |
-    +--------------------+------------------------+
-    | `Pyramid`_         | `pyramid_celery`_      |
-    +--------------------+------------------------+
-    | `Pylons`_          | `celery-pylons`_       |
-    +--------------------+------------------------+
-    | `Flask`_           | not needed             |
-    +--------------------+------------------------+
-    | `web2py`_          | `web2py-celery`_       |
-    +--------------------+------------------------+
-    | `Tornado`_         | `tornado-celery`_      |
-    +--------------------+------------------------+
-
-The integration packages are not strictly necessary, but they can make
-development easier, and sometimes they add important hooks like closing
-database connections at ``fork``.

- celery - Distributed Task Queue
-=================================

-
-:Version: 3.1.26 (Cipater)
-:Web: http://celeryproject.org/
-:Download: http://pypi.python.org/pypi/celery/
-:Source: http://github.com/celery/celery/
-:Keywords: task queue, job queue, asynchronous, async, rabbitmq, amqp, redis,
-  python, webhooks, queue, distributed

---
-
-What is a Task Queue?
-=====================
-
-Task queues are used as a mechanism to distribute work across threads or
-machines.
-
-A task queue's input is a unit of work, called a task, dedicated worker
-processes then constantly monitor the queue for new work to perform.
-
-Celery communicates via messages, usually using a broker
-to mediate between clients and workers.  To initiate a task a client puts a
-message on the queue, the broker then delivers the message to a worker.
-
-A Celery system can consist of multiple workers and brokers, giving way
-to high availability and horizontal scaling.
-
-Celery is a library written in Python, but the protocol can be implemented in
-any language.  So far there's RCelery_ for the Ruby programming language, and a
-`PHP client`, but language interoperability can also be achieved
-by using webhooks.
-
-.. _RCelery: http://leapfrogdevelopment.github.com/rcelery/
-.. _`PHP client`: https://github.com/gjedeer/celery-php
-.. _`using webhooks`:
-    http://docs.celeryproject.org/en/latest/userguide/remote-tasks.html
-
-What do I need?
-===============
-
-Celery version 3.0 runs on,
-
-- Python (2.5, 2.6, 2.7, 3.2, 3.3)
-- PyPy (1.8, 1.9)
-- Jython (2.5, 2.7).
-
-This is the last version to support Python 2.5,
-and from Celery 3.1, Python 2.6 or later is required.
-The last version to support Python 2.4 was Celery series 2.2.
-
-*Celery* is usually used with a message broker to send and receive messages.
-The RabbitMQ, Redis transports are feature complete,
-but there's also experimental support for a myriad of other solutions, including
-using SQLite for local development.
-
-*Celery* can run on a single machine, on multiple machines, or even
-across datacenters.
-
-Get Started
-===========
-
-If this is the first time you're trying to use Celery, or you are
-new to Celery 3.0 coming from previous versions then you should read our
-getting started tutorials:
-
-- `First steps with Celery`_
-
-    Tutorial teaching you the bare minimum needed to get started with Celery.
-
-- `Next steps`_
-
-    A more complete overview, showing more features.
-
-.. _`First steps with Celery`:
-    http://docs.celeryproject.org/en/latest/getting-started/first-steps-with-celery.html
-
-.. _`Next steps`:
-    http://docs.celeryproject.org/en/latest/getting-started/next-steps.html
-
-Celery is...
-============
-
-- **Simple**
-
-    Celery is easy to use and maintain, and does *not need configuration files*.
-
-    It has an active, friendly community you can talk to for support,
-    including a `mailing-list`_ and and an IRC channel.
-
-    Here's one of the simplest applications you can make::
-
-        from celery import Celery
-
-        app = Celery('hello', broker='amqp://guest@localhost//')
-
-        @app.task
-        def hello():
-            return 'hello world'
-
-- **Highly Available**
-
-    Workers and clients will automatically retry in the event
-    of connection loss or failure, and some brokers support
-    HA in way of *Master/Master* or *Master/Slave* replication.
-
-- **Fast**
-
-    A single Celery process can process millions of tasks a minute,
-    with sub-millisecond round-trip latency (using RabbitMQ,
-    py-librabbitmq, and optimized settings).
-
-- **Flexible**
-
-    Almost every part of *Celery* can be extended or used on its own,
-    Custom pool implementations, serializers, compression schemes, logging,
-    schedulers, consumers, producers, autoscalers, broker transports and much more.
-
-It supports...
-==============
-
-    - **Message Transports**
-
-        - RabbitMQ_, Redis_,
-        - MongoDB_ (experimental), Amazon SQS (experimental),
-        - CouchDB_ (experimental), SQLAlchemy_ (experimental),
-        - Django ORM (experimental), `IronMQ`_
-        - and more...
-
-    - **Concurrency**
-
-        - Prefork, Eventlet_, gevent_, threads/single threaded
-
-    - **Result Stores**
-
-        - AMQP, Redis
-        - memcached, MongoDB
-        - SQLAlchemy, Django ORM
-        - Apache Cassandra, IronCache
-
-    - **Serialization**
-
-        - *pickle*, *json*, *yaml*, *msgpack*.
-        - *zlib*, *bzip2* compression.
-        - Cryptographic message signing.

-Framework Integration
-=====================
-
-Celery is easy to integrate with web frameworks, some of which even have
-integration packages:
-
-    +--------------------+------------------------+
-    | `Django`_          | not needed             |
-    +--------------------+------------------------+
-    | `Pyramid`_         | `pyramid_celery`_      |
-    +--------------------+------------------------+
-    | `Pylons`_          | `celery-pylons`_       |
-    +--------------------+------------------------+
-    | `Flask`_           | not needed             |
-    +--------------------+------------------------+
-    | `web2py`_          | `web2py-celery`_       |
-    +--------------------+------------------------+
-    | `Tornado`_         | `tornado-celery`_      |
-    +--------------------+------------------------+
-
-The integration packages are not strictly necessary, but they can make
-development easier, and sometimes they add important hooks like closing
-database connections at ``fork``.

-    is the number of CPUs available on your system.
-
-.. cmdoption:: -P, --pool
-
-    Pool implementation:
-
-    prefork (default), eventlet, gevent, solo or threads.
-
-.. cmdoption:: -f, --logfile
-
-    Path to log file. If no logfile is specified, `stderr` is used.
-
-.. cmdoption:: -l, --loglevel
-
-    Logging level, choose between `DEBUG`, `INFO`, `WARNING`,
-    `ERROR`, `CRITICAL`, or `FATAL`.

-.. cmdoption:: -n, --hostname
-
-    Set custom hostname, e.g. 'w1.%h'. Expands: %h (hostname),
-    %n (name) and %d, (domain).
-
-.. cmdoption:: -B, --beat

-    Also run the `celery beat` periodic task scheduler. Please note that
-    there must only be one instance of this service.
-
-.. cmdoption:: -Q, --queues
-
-    List of queues to enable for this worker, separated by comma.
-    By default all configured queues are enabled.
-    Example: `-Q video,image`
-
-.. cmdoption:: -I, --include
-
-    Comma separated list of additional modules to import.
-    Example: -I foo.tasks,bar.tasks
-
-.. cmdoption:: -s, --schedule
-
-    Path to the schedule database if running with the `-B` option.
-    Defaults to `celerybeat-schedule`. The extension ".db" may be
-    appended to the filename.
-
-.. cmdoption:: -O
-
-    Apply optimization profile.  Supported: default, fair
-
-.. cmdoption:: --scheduler
-
-    Scheduler class to use. Default is celery.beat.PersistentScheduler
-
-.. cmdoption:: -S, --statedb
-
-    Path to the state database. The extension '.db' may
-    be appended to the filename. Default: {default}
-
-.. cmdoption:: -E, --events
-
-    Send events that can be captured by monitors like :program:`celery events`,
-    `celerymon`, and others.
-
-.. cmdoption:: --without-gossip
-
-    Do not subscribe to other workers events.
-
-.. cmdoption:: --without-mingle
-
-    Do not synchronize with other workers at startup.
-
-.. cmdoption:: --without-heartbeat
-
-    Do not send event heartbeats.
-
-.. cmdoption:: --heartbeat-interval
-
-    Interval in seconds at which to send worker heartbeat
-
-.. cmdoption:: --purge
-
-    Purges all waiting tasks before the daemon is started.
-    **WARNING**: This is unrecoverable, and the tasks will be
-    deleted from the messaging server.
-
-.. cmdoption:: --time-limit
-
-    Enables a hard time limit (in seconds int/float) for tasks.
-
-.. cmdoption:: --soft-time-limit
-
-    Enables a soft time limit (in seconds int/float) for tasks.
-
-.. cmdoption:: --maxtasksperchild
-
-    Maximum number of tasks a pool worker can execute before it's
-    terminated and replaced by a new worker.
-
-.. cmdoption:: --pidfile
-
-    Optional file used to store the workers pid.
-
-    The worker will not start if this file already exists
-    and the pid is still alive.
-
-.. cmdoption:: --autoscale
-
-    Enable autoscaling by providing
-    max_concurrency, min_concurrency. Example::
-
-        --autoscale=10,3
-
-    (always keep 3 processes, but grow to 10 if necessary)
-
-.. cmdoption:: --autoreload
-
-    Enable autoreloading.
-
-.. cmdoption:: --no-execv
-
-    Don't do execv after multiprocessing child fork.

-=========================
-Abortable tasks overview
-=========================
-
-For long-running :class:`Task`'s, it can be desirable to support
-aborting during execution. Of course, these tasks should be built to
-support abortion specifically.
-
-The :class:`AbortableTask` serves as a base class for all :class:`Task`
-objects that should support abortion by producers.
-
-* Producers may invoke the :meth:`abort` method on
-  :class:`AbortableAsyncResult` instances, to request abortion.
-
-* Consumers (workers) should periodically check (and honor!) the
-  :meth:`is_aborted` method at controlled points in their task's
-  :meth:`run` method. The more often, the better.
-
-The necessary intermediate communication is dealt with by the
-:class:`AbortableTask` implementation.
-
-Usage example
--------------
-
-In the consumer:
-
-.. code-block:: python
-
-    from __future__ import absolute_import
-
-    from celery.contrib.abortable import AbortableTask
-    from celery.utils.log import get_task_logger
-
-    from proj.celery import app
-
-    logger = get_logger(__name__)
-
-    @app.task(bind=True, base=AbortableTask)
-    def long_running_task(self):
-        results = []
-        for i in range(100):
-            # check after every 5 iterations...
-            # (or alternatively, check when some timer is due)
-            if not i % 5:
-                if self.is_aborted():
-                    # respect aborted state, and terminate gracefully.
-                    logger.warning('Task aborted')
-                    return
-                value = do_something_expensive(i)
-                results.append(y)
-        logger.info('Task complete')
-        return results
-
-In the producer:
-
-.. code-block:: python
-
-    from __future__ import absolute_import
-
-    import time
-
-    from proj.tasks import MyLongRunningTask
-
-    def myview(request):
-        # result is of type AbortableAsyncResult
-        result = long_running_task.delay()
-
-        # abort the task after 10 seconds
-        time.sleep(10)
-        result.abort()
-
-After the `result.abort()` call, the task execution is not
-aborted immediately. In fact, it is not guaranteed to abort at all. Keep
-checking `result.state` status, or call `result.get(timeout=)` to
-have it block until the task is finished.
-
-.. note::
-
-   In order to abort tasks, there needs to be communication between the
-   producer and the consumer.  This is currently implemented through the
-   database backend.  Therefore, this class will only work with the
-   database backends.

-celery.contrib.batches
-======================
-
-Experimental task class that buffers messages and processes them as a list.
-
-.. warning::
-
-    For this to work you have to set
-    :setting:`CELERYD_PREFETCH_MULTIPLIER` to zero, or some value where
-    the final multiplied value is higher than ``flush_every``.
-
-    In the future we hope to add the ability to direct batching tasks
-    to a channel with different QoS requirements than the task channel.
-
-**Simple Example**
-
-A click counter that flushes the buffer every 100 messages, and every
-10 seconds.  Does not do anything with the data, but can easily be modified
-to store it in a database.
-
-.. code-block:: python
-
-    # Flush after 100 messages, or 10 seconds.
-    @app.task(base=Batches, flush_every=100, flush_interval=10)
-    def count_click(requests):
-        from collections import Counter
-        count = Counter(request.kwargs['url'] for request in requests)
-        for url, count in count.items():
-            print('>>> Clicks: {0} -> {1}'.format(url, count))
-
-
-Then you can ask for a click to be counted by doing::
-
-    >>> count_click.delay(url='http://example.com')
-
-**Example returning results**
-
-An interface to the Web of Trust API that flushes the buffer every 100
-messages, and every 10 seconds.
-
-.. code-block:: python
-
-    import requests
-    from urlparse import urlparse
-
-    from celery.contrib.batches import Batches
-
-    wot_api_target = 'https://api.mywot.com/0.4/public_link_json'
-
-    @app.task(base=Batches, flush_every=100, flush_interval=10)
-    def wot_api(requests):
-        sig = lambda url: url
-        reponses = wot_api_real(
-            (sig(*request.args, **request.kwargs) for request in requests)
-        )
-        # use mark_as_done to manually return response data
-        for response, request in zip(reponses, requests):
-            app.backend.mark_as_done(request.id, response)
-
-
-    def wot_api_real(urls):
-        domains = [urlparse(url).netloc for url in urls]
-        response = requests.get(
-            wot_api_target,
-            params={'hosts': ('/').join(set(domains)) + '/'}
-        )
-        return [response.json()[domain] for domain in domains]
-
-Using the API is done as follows::
-
-    >>> wot_api.delay('http://example.com')
-
-.. note::
-
-    If you don't have an ``app`` instance then use the current app proxy
-    instead::

-        from celery import current_app
-        app.backend.mark_as_done(request.id, response)

-celery.contrib.methods
-======================
-
-Task decorator that supports creating tasks out of methods.
-
-Examples
---------
-
-.. code-block:: python
-
-    from celery.contrib.methods import task
-
-    class X(object):
-
-        @task()
-        def add(self, x, y):
-                return x + y
-
-or with any task decorator:
-
-.. code-block:: python
-
-    from celery.contrib.methods import task_method
-
-    class X(object):
-
-        @app.task(filter=task_method)
-        def add(self, x, y):
-            return x + y
-
-.. note::
-
-    The task must use the new Task base class (:class:`celery.Task`),
-    and the old base class using classmethods (``celery.task.Task``,
-    ``celery.task.base.Task``).
-
-    This means that you have to use the task decorator from a Celery app
-    instance, and not the old-API:
-
-    .. code-block:: python
-
-
-        from celery import task       # BAD
-        from celery.task import task  # ALSO BAD
-
-        # GOOD:
-        app = Celery(...)
-
-        @app.task(filter=task_method)
-        def foo(self): pass
-
-        # ALSO GOOD:
-        from celery import current_app
-
-        @current_app.task(filter=task_method)
-        def foo(self): pass
-
-        # ALSO GOOD:
-        from celery import shared_task
-
-        @shared_task(filter=task_method)
-        def foo(self): pass
-
-Caveats
--------
-
-- Automatic naming won't be able to know what the class name is.
-
-    The name will still be module_name + task_name,
-    so two methods with the same name in the same module will collide
-    so that only one task can run:
-
-    .. code-block:: python
-
-        class A(object):
-
-            @task()
-            def add(self, x, y):
-                return x + y
-
-        class B(object):
-
-            @task()
-            def add(self, x, y):
-                return x + y
-
-    would have to be written as:
-
-    .. code-block:: python
-
-        class A(object):
-            @task(name='A.add')
-            def add(self, x, y):
-                return x + y
-
-        class B(object):
-            @task(name='B.add')
-            def add(self, x, y):
-                return x + y

-    to specify the destination to where the task should be moved,
-    or a :class:`~kombu.entitiy.Queue` instance.

-celery.contrib.rdb
-==================
-
-Remote debugger for Celery tasks running in multiprocessing pool workers.
-Inspired by http://snippets.dzone.com/posts/show/7248
-
-**Usage**
-
-.. code-block:: python
-
-    from celery.contrib import rdb
-    from celery import task
-
-    @task()
-    def add(x, y):
-        result = x + y
-        rdb.set_trace()
-        return result
-
-
-**Environment Variables**
-
-.. envvar:: CELERY_RDB_HOST
-
-    Hostname to bind to.  Default is '127.0.01', which means the socket
-    will only be accessible from the local host.
-
-.. envvar:: CELERY_RDB_PORT
-
-    Base port to bind to.  Default is 6899.
-    The debugger will try to find an available port starting from the
-    base port.  The selected port will be logged by the worker.

-**Usage**
-
-Add the extension to your :file:`docs/conf.py` configuration module:
-
-.. code-block:: python
-
-    extensions = (...,
-                  'celery.contrib.sphinx')
-
-If you would like to change the prefix for tasks in reference documentation
-then you can change the ``celery_task_prefix`` configuration value:
-
-.. code-block:: python
-
-    celery_task_prefix = '(task)'  # < default
-
-
-With the extension installed `autodoc` will automatically find
-task decorated objects and generate the correct (as well as
-add a ``(task)`` prefix), and you can also refer to the tasks
-using `:task:proj.tasks.add` syntax.
-
-Use ``.. autotask::`` to manually document a task.

-    celery.events.state
-    ~~~~~~~~~~~~~~~~~~~
-
-    This module implements a datastructure used to keep
-    track of the state of a cluster of workers and the tasks
-    it is working on (by consuming events).
-
-    For every event consumed the state is updated,
-    so the state represents the state of the cluster
-    at the time of the last event.
-
-    Snapshots (:mod:`celery.events.snapshot`) can be used to
-    take "pictures" of this state at regular intervals
-    to e.g. store that in a database.

-    you would like the task to execute. It is a reasonably complete
-    implementation of cron's features, so it should provide a fair
-    degree of scheduling needs.
-
-    You can specify a minute, an hour, a day of the week, a day of the
-    month, and/or a month in the year in any of the following formats:
-
-    .. attribute:: minute
-
-        - A (list of) integers from 0-59 that represent the minutes of
-          an hour of when execution should occur; or
-        - A string representing a crontab pattern.  This may get pretty
-          advanced, like `minute='*/15'` (for every quarter) or
-          `minute='1,13,30-45,50-59/2'`.
-
-    .. attribute:: hour
-

-          a day of when execution should occur; or
-        - A string representing a crontab pattern.  This may get pretty
-          advanced, like `hour='*/3'` (for every three hours) or
-          `hour='0,8-17/2'` (at midnight, and every two hours during
-          office hours).
-
-    .. attribute:: day_of_week
-
-        - A (list of) integers from 0-6, where Sunday = 0 and Saturday =
-          6, that represent the days of a week that execution should
-          occur.
-        - A string representing a crontab pattern.  This may get pretty
-          advanced, like `day_of_week='mon-fri'` (for weekdays only).
-          (Beware that `day_of_week='*/2'` does not literally mean
-          'every two days', but 'every day that is divisible by two'!)
-
-    .. attribute:: day_of_month
-
-        - A (list of) integers from 1-31 that represents the days of the
-          month that execution should occur.
-        - A string representing a crontab pattern.  This may get pretty
-          advanced, such as `day_of_month='2-30/3'` (for every even
-          numbered day) or `day_of_month='1-7,15-21'` (for the first and
-          third weeks of the month).
-
-    .. attribute:: month_of_year
-
-        - A (list of) integers from 1-12 that represents the months of
-          the year during which execution can occur.
-        - A string representing a crontab pattern.  This may get pretty
-          advanced, such as `month_of_year='*/3'` (for the first month

-        (:class:`~datetime.datetime`).
-
-    .. attribute:: app
-
-        The Celery app instance.
-
-    It is important to realize that any day on which execution should
-    occur must be represented by entries in all three of the day and
-    month attributes.  For example, if `day_of_week` is 0 and `day_of_month`
-    is every seventh day, only months that begin on Sunday and are also
-    in the `month_of_year` attribute will have execution events.  Or,
