Registered usernames can no longer be used by an anonymous author

Until now a registered user has been able to make a change without authenticating, by entering their username in the author field. Any user could make a comment using a registered username. While this hasn't been a significant problem up until now, it was possible that a user could make changes with malicious intent, disguising themselves as a registered user. The issue was discussed in #11622 and changes have been deployed to

Please note that you are still free to make a comment or create a ticket using a username or email that has not been registered at If you have any questions or concerns please leave a comment below.

Elevated permissions

The permission schema has been modified to give users additional permissions:

  1. Anonymous users can modify ticket properties (TICKET_CHGPROP).
  2. Authenticated users can delete their own attachments.
  3. Authenticated users can modify the description of tickets they report.
  4. Project maintainers can modify the ticket description, cc list and edit comments by others, for tickets associated with their projects.
  5. Project maintainers can delete attachments on their project wiki page and for tickets associated with their projects.

Trac Hacks upgraded to Trac 1.2

The site is now running Trac 1.2. Trac 1.2 is the latest stable release at the time of this writing, and we'll aim to keep on the latest release of Trac going forward.

There was a small amount of downtime related to the upgrade which will be avoided in the future through improved configuration management.

[RESOLVED] Usernames with special characters can't login

Due to a regression in Trac 1.0.7, attempts to login to the site with a username containing special characters such as . or - will result in an error. The issue is captured in trac:#12129 and should be resolved with a new Trac release this week.

Welcome to Trac Hacks

The purpose of TracHacks is to provide free Subversion hosting for community created Trac hacks.

TracHacks uses the excellent TagsPlugin, which adds basic categorisation to Trac. All hacks are tagged with one or more of the available tags?.

How to Contribute

I've tried to make this as simple as possible:

  1. Register? a user name then login? (requires cookies).
  2. Fill out the NewHack form.
  3. Verify all the details for your new page are correct.
  4. Commit your code to the provided Subversion URL
    (alternatively you can simply attach your hack to your Wiki page, ala MacroBazaar, but remember that you can't delete or replace attachments)
  5. Have a look at TracHackDevelopment.
  6. Consider subscribing to the trac-hacks mailing list.

The TracHacks page contains more information, contact details, bug reports, enhancements, suggestions, etc.

I host my own hack elsewhere

Feel free to create a stub page here with a short description and links to your own hack. Please stick to the page naming convention, by appending the hack type (eg. GanttPlugin)

eg. The DoStuff macro would become the page DoStuffMacro.

Once you have created your page, tag it with the hack type and it will appear on the front page. Tag it with your TracHacks user id if you want it to show up on your user page.

How to Adopt Unmaintained Hacks

How do I install these things?

Refer to the Trac plugin documentation and the MacroBazaar for details on how to build and install plugins and macros, respectively. For other types please refer to the page of the hack you are installing for instructions.


Have a look at the RequestaHack page for features that people request.



Macros are simple enhancements to Trac's Wiki engine. Examples include SubWiki, TOC, FootNote, etc.

The TracWorkflow is customizable.
