Existing bugs and feature requests for AttachFilterPlugin are here.

If you have any issues, create a new ticket.


Download the zipped source from [download:attachfilterplugin here].


You can check out AttachFilterPlugin from here using Subversion, or browse the source with Trac.


In trac.ini, add a new section [attachment_filter], where:

  • keys match the mime file type to exclude
  • values gives a brief description that is shown to the user to explain why the file is rejected


application/ = Microsoft Excel documents should be attached as PDF files
application/ = Microsoft PowerPoint documents should be attached as PDF files
application/msword = Microsoft Word documents should be attached as PDF files
image/bmp = Microsoft bitmap images should be attached as PNG images

Yep, M$ is evil :-)

MIME type

To obtain the exact MIME type string:

  1. set up your Trac installation to show/dump INFO log message,
  2. attach a file of the (un)desired type
  3. look for the plugin trace that shows the file name and the MIME type:
    grep Filename .../log/trac.log
    2011-05-16 15:49:26,299 Trac[filter] INFO: Filename stuff.doc, filetype application/msword
  4. add this new MIME type to the [attachment_filter] section
  5. restart your Trac engine
