Introduction
************

``birdhousebuilder.recipe.pywps`` is a `Buildout`_ recipe to install and configure `PyWPS`_ with `Anaconda`_. `PyWPS`_ is a Python implementation of a `Web Processing Service`_ (WPS). ``PyWPS`` will be deployed as a `Supervisor`_ service and is available behind a `Nginx`_ web server.
This recipe is used by the `Birdhouse`_ project.

Usage
*****

The recipe requires that Anaconda is already installed. You can use the buildout option ``anaconda-home`` to set the prefix for the anaconda installation. Otherwise the environment variable ``CONDA_PREFIX`` (variable is set when activating a conda environment) is used as conda prefix.

It installs the ``pywps`` package from a conda channel in a conda environment defined by ``CONDA_PREFIX``. The location of the intallation is given by the ``prefix`` buildout option. It setups a `PyWPS`_ output folder in ``${prefix}/var/lib/pywps``. It deploys a `Supervisor`_ configuration for ``PyWPS`` in ``${prefix}/etc/supervisor/conf.d/pywps.conf``. Supervisor can be started with ``${prefix}/etc/init.d/supervisor start``.

The recipe will install the ``nginx`` package from a conda channel and deploy a Nginx site configuration for ``PyWPS``. The configuration will be deployed in ``${prefix}/etc/nginx/conf.d/pywps.conf``. Nginx will be started by supervisor.

By default ``PyWPS`` will be available on http://localhost:8091/wps?service=WPS&version=1.0.0&request=GetCapabilities.

The recipe depends on:

* ``birdhousebuilder.recipe.conda``,
* ``birdhousebuilder.recipe.supervisor``,
* ``birdhousebuilder.recipe.nginx`` and
* ``zc.recipe.deployment``.

Supported options
=================

The PyWPS options which are configured by buildout are explained in the `PyWPS documentation`_.

The recipe supports the following buildout options:

**anaconda-home**
   Buildout option pointing to the root folder of the Anaconda installation. Default: ``$HOME/anaconda``.

Buildout options for ``pywps``:

**prefix**
  Deployment option to set the prefix of the installation folder. Default: ``/``

**user**
  Deployment option to set the run user.

**etc-user**
  Deployment option to set the user of the ``/etc`` directory. Default: ``root``

**name**
   The name of your WPS project (used for config names and folder path).

**hostname**
   The hostname of the ``PyWPS`` service (nginx). Default: ``localhost``

**http-port**
   The http port of the ``PyWPS`` service (nginx). Default: ``8091``

**https-port**
   The https port of the ``PyWPS`` service (nginx). Default: ``28091``

**http-output-port**, **output-port**
   The http port of the ``PyWPS`` output file service (nginx). Default: ``8090``

**https-output-port**
   The https port of the ``PyWPS`` output file service (nginx). Default: ``28090``

**workers**
   The number of gunicorn workers for handling requests. Default: 1

**processes-import**
   Python package with processes.

**processes-path**
   Path the ``PyWPS`` processes.

**title**
   Title used for your WPS service.

**abstract**
   Description of your WPS service.

**loglevel**
   Logging level for ``PyWPS``. Default: ``WARN``

**logformat**
   Logging string format for ``PyWPS``. Default: ``%(asctime)s] [%(levelname)s] line=%(lineno)s module=%(module)s %(message)s``

**parallelprocesses**
   Maximum number of parallel running processes.
   The effective number of parallel running processes is limited by the number of cores
   in the hosting machine. Default: 2

**maxprocesses**
   Maximum number of processes which are accepted in the queue. Default: 30

**maxrequestsize**
   Maximal request size accepted in WPS process. Default: 30mb


Example usage
=============

The following example ``buildout.cfg`` installs ``PyWPS`` with Anaconda::

  [buildout]
  parts = pywps

  [pywps]
  recipe = birdhousebuilder.recipe.pywps
  name = myproject
  prefix = /
  user = www-data
  hostname = localhost
  http-port = 8091
  https-port = 28091

  # pywps options
  processes-import = myproject.processes
  processes-path = ${buildout:directory}/myproject/processes
  title = MyProject ...
  abstract = MyProject does ...

After installing with Buildout start the ``PyWPS`` service with::

  $ cd ${prefix}
  $ etc/init.d/supervisord start  # start|stop|restart
  $ etc/init.d/nginx start        # start|stop|restart
  $ bin/supervisorctl status      # check that pycsw is running
  $ less var/log/pywps/myproject.log  # check log file

  http://localhost:8091/wps?service=WPS&version=1.0.0&request=GetCapabilities
