Deliverance transforms HTML to theme pages
Deliverance does transformations of HTML to ‘theme’ pages, similar in function to XSLT but using a simpler XML-based language to express the transformation.
New in this release:
The paste.deploy configuration and middleware factory now accept a theme_uri parameter.
If used, this will be the global default theme uri. It will be used if no theme is defined within the ruleset.
Internal subrequests that return non-200 response codes are now retried as external HTTP requests. (#16)
Request/response matching in <rule> elements now work. (#6)
<meta http-equiv=”Content-Type”> tags are no longer stripped from documents. Instead, they are always included in the output of Deliverance, with a default charset of ASCII. (#34)
CDATA sections in XHTML documents are left as-is instead of being incorrectly escaped. (#36)
Before applying the rules, Deliverance now moves the <meta> tag with a charset declaration to be the first child of the <head> element, if both are present. This ensures that non-ASCII characters in the <head> are converted to the correct HTML sequences. (#12)
There is now a garbage-collecting WSGI middleware deliverance.garbagecollect, disabled by default, which calls gc.collect() after every request. This was added after a report (unconfirmed) of potential memory leaks when using some versions of lxml. (#22)
You can use it with deliverance-proxy –garbage-collect or, in paste.deploy configurations, filter your app with use = egg:Deliverance#garbagecollect.
