Products.PortalTransforms 2.1.2

MIME based content transformations

Latest Version: 2.1.3

Introduction

This Zope product provides two new tools for the CMF in order to make MIME types based transformations on the portal contents, and so an easy to way to plugin some new transformations for previously unsupported content types. The provided tools are:

portal_transform (the transform tool)
handle transformation of data from a mime type to another

A bunch of ready to use transformations are also provided. Look at the documentation for more information.

Notice this package can also be used as a standalone Python package. If you've downloaded the Python distribution, you can't make it a Zope product since Zope files have been removed from this distribution.

This product is an off-spring of the Archetypes project.

Changelog

2.1.2 (2012-12-09)

2.1.1 (2012-10-05)

  • Do not try to handle invalid tags : we take for granted that html coming out of converters do not hold any of embed, script, object or applet tags.

2.1 (2012-10-05)

  • Avoid throwing exceptions on js attrs and invalid tags in word_to_html transform [gotcha]
  • Handle charrefs & entityrefs in data and attributes equaly (unchanged) if converting to safe_html [tom_gross]

2.0.7 - 2011-07-04

The following three changes collectively fix http://plone.org/products/plone/security/advisories/CVE-2011-1949

  • In the safe_html transform, abort parsing if a broken declaration is found. [evilbungle, davisagli]
  • In the safe_html transform, remove data URIs. [davisagli]
  • In the safe_html transform, ignore null bytes when checking for unsafe attributes with scripts. [davisagli]

2.0.6 - 2011-04-03

  • Update RoleManager import to avoid deprecation warning on Zope 2.13. [davisagli]

2.0.5 - 2011-02-26

  • Fix regression due to the security declarations added in 2.0.4: convertTo should still be public, but not publishable. [davisagli]

2.0.4 - 2011-02-25

  • Fix missing security declarations. [davisagli]

2.0.3 - 2010-11-24

  • Fix manage_options which accidentally got turned into a tuple in some refactoring. [swampmonkey]
  • Added missing url metadata. [hannosch]

2.0.2 - 2010-10-27

  • Close <p> tags properly in configureTransform.zpt. [swampmonkey]
  • Add HTML5 tags as valid: article, aside, audio, canvas, command, datalist, details, figcaption, figure, footer, header, hgroup, keygen, mark, rp, rt, ruby, section, source, summary, time, video. [limi]

2.0.1 - 2010-07-18

  • Use the standard libraries doctest module. [hannosch]
  • Added padding-left to the style whitelist, to let TinyMCE's indent work. This closes http://dev.plone.org/plone/ticket/10557. [hannosch]
  • PEP8 adjustments for the safe_html transform. [hannosch]

2.0 - 2010-07-16

  • Lower test requirements for transform tests to only check the start of each file. There's too many subtle differences in the exact output on different machines. [hannosch]
  • PEP8 cleanup of the transform engine code. [hannosch]

2.0b6 - 2010-06-13

  • Repeat safe_html transform to block a malicious HTML injection vector. Thanks to evilbungle for the report. [MatthewWilkes]

2.0b5 - 2010-04-10

  • Let mimetype maps with empty transform lists be handled more gracefully. Fixes: http://dev.plone.org/plone/ticket/10402, refs: r12421. [thet]
  • Fixed a problem where the cache would return data from transforms which are sensitive to virtual hosting (such as the resolve UID transforms used by visual editors) which had been cached for a different virtual host. [rossp]

2.0b4 - 2010-03-01

  • Restore output/logo.jpg and output/logo.bmp from 1.6 branch. [stefan]

2.0b3 - 2010-02-19

  • Make tests pass with poppler's pdftohtml converter. Standalone pdftohtml produces different output and should be avoided. [stefan]

2.0b2 - 2010-02-05

  • Updated expected output images to most current format. [hannosch]

2.0b1 - 2010-01-03

  • Fixed a serious performance issue in the find transform path algorithm. This refs http://dev.plone.org/plone/ticket/9497. [hannosch, sig]
  • Protect against failures in the transform engine, which prevented zexp imports of sites. [hannosch]
  • Fixed package dependency declaration. [hannosch]

2.0a2 - 2009-12-02

  • Added HTML5 tags as allowed tags. [limi]
  • Made sure the meta tag is stripped, since not doing it can let things like HTML redirects slip through, which makes for unpredictable behavior. [limi]
  • Added style to nasty tags, addresses http://dev.plone.org/plone/ticket/9015. [jonstahl]

2.0a1 - 2009-11-13

  • Downgraded log messages about unavailable binaries to debug level. [hannosch]
  • Updated test output to be compatible with docutils 0.5. [hannosch]
  • Removed z3 sub-package. Interfaces are in the interfaces module. [hannosch]
  • Cleaned up package metadata. [hannosch]
  • Declare test dependencies in an extra and fixed deprecation warnings for use of Globals. [hannosch]
  • Made the graph tests conditional on the availability of the external binaries for the transform. [hannosch]
  • Removed useless assert statements. [hannosch]
  • Structured Text is gone in Zope 2.12. [hannosch]
  • Transforms to target mimetype with multiple alias mimetypes in mimetypes_registry failed. This closes http://dev.plone.org/plone/ticket/8187. [hannosch]
  • Added logging to markdown and textile transforms if the libraries are not installed. This closes http://dev.plone.org/plone/ticket/8285. [hannosch]
  • Purge old zope2 Interface interfaces for Zope 2.12 compatibility. Consider branching before this checkin if releases required before Plone 4. [elro]

  • Added metadata.xml file to the profile. [hannosch]
  • Allowed the abbr, acronym, var, dfn, samp, address, bdo, thead, tfoot, col, and colgroup tags by default, since they are harmless, valid XHTML and shouldn't be filtered. Fixes: http://dev.plone.org/plone/ticket/6712 and http://dev.plone.org/plone/ticket/7251 [limi]
  • Added proper Z3 interfaces and added direct implements statements instead of applying the changes later on with zcml. Reduced number of zcml files to one. [hannosch]

We dont need increasing of release numbers because of Plone 3.0, Archetypes 1.5, ... if theres no change in the dependen product, like this one. [jensens]

1.5.0-final - 2006-12-15

1.5.0-a1 - 2006-10-25

  • casting to int is evil without previous check of the type. so we assume as in CMFPlone just zero for non-int-castable values. [jensens]

  • Replaced the safe_html transformation with a configurable version with the same functionality. Migration is handled on reinstall. http://trac.plone.org/plone/ticket/4538 [csenger] [dreamcatcher]
  • Removed CoUnInitialize call. According to Mark Hammond: The right thing to do is call that function, although almost noone does (including pywin32 itself, which does CoInitialize the main thread) and I've never heard of problem caused by this omission. [sidnei]
  • Fix a long outstanding issue with improper COM thread model initialization. Initialize COM for multi-threading, ignoring any errors when someone else has already initialized differently. https://trac.plone.org/plone/ticket/4712 [sidnei]

  • Fixed the requirements look-up from the policy (#1358085)
