There are two primary ways to log bug reports, patches, or feature requests:

  1. email the ns-developers mailing list (you will need to subscribe to the list to be able to post, and first-time posts are moderated); or
  2. enter the bug into the bugzilla database yourself

We strongly prefer the second approach; email to the mailing list runs the risk of falling through the cracks. The second approach requires you to create a Bugzilla account, which can no longer be done automatically but can be set up by requesting an account from

If you think you’ve found a bug and want to report it, please do the following three things first:

  1. search bugzilla to see if someone has entered a similar bug.
  2. search Google to see if the bug has been previously encountered and discussed on an email thread
  3. if you are new to reporting bugs, please read the bug writing guidelines on Bugzilla

Fixing bugs is even more preferred than reporting them. This is typically done by uploading a patch on an existing bug, or filing a bug and immediately filing a patch on it. If you are not familiar with how to prepare patch files, please read this first. You should find the “Create a New Attachment” choice when editing the bug, allowing you to upload a patch. Alternatively, you could provide a URL to a patch in the “Description” field.

Note that providing a simple, reduced test case that reliably reproduces the bug is often requested by the maintainers, so please try to craft such a test case and upload it to the tracker.
