Add comments to wiki pages


The AddCommentMacro allows for easy addition of comments to a page, in a standard format. Each comment added is in the following form:

==== Comment by <user> on <date> ====

The comment body supports normal TracWiki WikiFormatting.

Comments are added after the first line that starts with [[AddComment]].

The AddCommentMacro supports previewing and adheres to the TracPermissions scheme, only allowing comments to be added if the user has write access to the page.

Since [21] the AddCommentMacro can fulfill the role of an append only Wiki page. By passing the argument appendonly to the macro, comments can be appended to the page even when the user does not have permission to modify the page. Potentially unsafe, but can be useful.

  • Wiki page preview got us a double set of editing toolbars. Fixed.
  • Also adding some extra logging and deleting the redirect marker in search of possible issue with redirect (that I can't replicate).

AddCommentMacro: Now calls wiki page manipulators to check content before saving. This means support for Spam Filter plugin and similar plugins that can veto any wiki page change.

Report and patch by Thomas Moschny. Closes #3076.
