Revision as of 22:05, 21 November 2022

This is a collection of small projects to start contributing to Octave. Projects of long duration are listed in the Projects page.
Info icon.svg
If you never contributed to Octave before, we suggest to start with our Developer FAQ.

Review and fix existing bugs

  • Review bugs that catch your interest on the Octave bug tracker on GNU Savannah.
    • A modern interface to the Octave bug tracker is given by SavannahAPI.
  • Discuss with the developers there how to fix that bug or upload a patch there.
  • Some bugs have already patches attached.
    • Help testing those patches.
    • Help updating outdated patches to the latest development version (this requires some Mercurial knowledge).

Implement missing Matlab functions

Use the Savannah patch tracker for submissions unrelated to an existing bug.

Write Built-In Self Tests (BISTs)

Writing BISTs improves Octave's regression testing and ensures that we don't break anything when we add new features.

Work on Octave packages

Easy Closes

Below is a non exhaustive list of bugs which should be looked at and appear to be easy Completed scrub using 6.1 as non expert.

Notes:

  • The last full scrub came from hardy for v4.2
  • Suspect many java bugs could be closed.
  • Appears plotting bugs have been fixed, but not have been reviewed for 5 years.
  • Did not include most documentation bugs.
  • Experts: rik5, nrjank, etc. will be able to find significantly more to close.

The equivalent suggestions for patches.

patch patch title status

A list of patch reports with attachments not marked "Done or Cancelled" can be viewed in the SavannaAPI, sorted by oldest first or sorted by "longest since last comment" first. While some of these older submissions may still be viable and just need a patch refresh to the current code base, many will have become out of date or rendered inapplicable due to code or function changes, and could be closed as 'Wont Fix'.
