plone.recipe.deliverance 1.0b4

Install the Deliverance proxy as an out-of-process transform.

To learn more about Deliverance, see http://openplans.org/projects/deliverance

This will probably only work on Unix systems. On Windows, you are likely to need to install binaries for lxml. Tested primarily on OS X. If you have got it to work on Windows, please let the author know!

Add this to your buildout.cfg:

[buildout]
parts = deliverance

[deliverance]
recipe = plone.recipe.deliverance

This will download the Deliverance egg and its dependencies. It will also fetch and build libxml2 and libxslt from source.

A new script will be written to the top-level ‘bin’ directory, called ‘deliverance’ (taken from the name of thes buildout part). This sets up the environment appropriately and then starts the Deliverance daemon.

A Deliverance configuration file will be generated in deliverance/deliverance-proxy.ini. You can edit this - it will not be overridden when buildout is re-run, although it will be re-generated if it is removed.

The files deliverance/rules/rules.xml and deliverance/rules/standardrules.xml contain a example rules. An example theme is installed in deliverance/static/theme.html. If you change these, they will not be overridden. If you remove the ‘rules’ and ‘static’ directories, they will be recreated with these example files, otherwise they are left alone.

Other possible options for the deliverance section include:

eggs – Any other eggs you may want to install. By default, this is just the

Deliverance egg (and its dependencies, of course).

scripts – Any console scripts to install. By default, this includes

‘paster’. Set this an empty value to disable script generation (for example if another recipe is installing ‘paster’)

paster – Path to a script to use to run ‘paster’. Defaults to the generated

‘paster’ script. This option is only needed if you disable script generation and there is no bin/paster in the buildout.

libxml2_url – A URL from which the libxml2 sources can be downloaded. If you

do not want libxml2 to be installed, set this to an empty value. Otherwise, a default “known good” version is downloaded and compiled.

libxslt_url – A URL from which libxslt sources can be downloaded. Again,

set this to an empty value to avoid compiling libxslt.

The following options affect the generated deliverance-proxy.ini configuration file.

debug – Set to true or false to enable or disable deliverance error

reporting.

host – The host to bind the Deliverance process to. By default, it will

listen to any IP address.

port – The port for the Deliverance process. Defaults to 8000.

proxy – The URL being proxied by Deliverance. Defaults to

http://localhost:8080.

theme – A URI for the theme. To specify a path relative to the ‘deliverance’

prefix it with “/.deliverance/”. The default is /.deliverance/static/theme.html

rules – A URI for the rules file. Again, use “/.deliverance” to specify a

path relative to the ‘deliverance’ directory. The default is /.deliverance/rules/rules.xml

rewrite – Rewrite all headers and internal links to appear to come from the

proxied server. Defaults to ‘true’.

transparent – Do not rewrite the Host header when passing on a request.

Defaults to ‘true’.
