Patch DocumentTemplate to not return any content.

Project description

Patch DocumentTemplate to not return any content.

Features

DTML documents have been deprecated for several years, at least within the Plone community. So you should not use them. But still Plone ships with DTML documents. And these may contain security issues, especially for Cross Site Scripting (CSS). So this package patches the Document Templates to not return any content.

Options

The package looks for a few environment variables.

SHOW_ORIGINAL_DTML
When this is set to a true value, the original DTML value is printed in the zope instance log. The arguments and keyword arguments are also shown, so you can know where this is coming from. Default: false.
DEBUG_DTML_VALUE
When this is set, the given value is return as content of the DTML. Default: empty string.
EXPERIMENTAL_NODTML_ONLY_WARN
When this is set to a true value, instead of replacing the dtml value, a warning is logged. When true, the SHOW_ORIGINAL_DTML and DEBUG_DTML_VALUE settings are ignored. Default: false.
EXPERIMENTAL_NODTML_RAISE
When this is set to a true value, instead of replacing the dtml value, an exception is raised. When true, the other settings are ignored. Default: false.

Accepted True values are: true, t, 1, yes, y.

Installation

Install experimental.nodtml by adding it to your buildout:

[buildout]
...
eggs =
    experimental.nodtml

and then running bin/buildout

No zcml is needed.

Supported Plone Versions

  • Plone 4.x
  • Plone 5.x

We are only patching DocumentTemplate so this works with any plain Zope2.
