Trac reCAPTCHA filter

Introduction

This filter uses the free service from http://recaptcha.net to check if a content submitter is a human or a computer. Once a captcha is solved it will allow a configurable number of submissions for a configurable time period until it requires another captcha to be solved.

• Release 1.9 packages the template files in the source tar.
• Release 1.8 changes how a submitted captcha is processed.
• Release 1.7 adds support for Trac 0.11, but drops mailhide as well as Trac 0.10 compatibility.
• Release 1.6 was originally never released, probably fixed some minor issues with 1.5.
• Release 1.5 includes mailhide functionality which hides most email addresses behind a captcha, if the email address is already a link for something else we show only the full name, or local part of the email address.
• Release 1.4 was the first public release.

Installation

• download the attached .egg file, copy it to $tracdir/plugins and restart trac.
