Sage has two build bots.

Release Buildbot

The first builds entire tarballs (e.g. all the alphas) on a wide variety of machines, and can be found at http://build.sagemath.org/sage/ .

Patch Buildbot

The second pulls and applies patches from Trac and can be found at http://patchbot.sagemath.org/ or from links on the individual Trac tickets. This is still very much a work in progress, but the latest version of the code lives at https://code.google.com/p/sage-buildbot/ . Eventually this will get moved into Sage where it can be edited using the standard procedures and more widely deployed.

Usage

The Patch Buildbot will automatically select patches (from the ticket attachments) to apply. Every Trac ticket has a Patch Buildbot report page, which is accessed by the swirly, round icon at the top of the ticket description. The report page lists the patches the buildbot chose. To override this choice, use the following directive in a ticket comment:

Any subsequently added patches will be (semi-intellegently) appended to the list. To tell Patch Buildbot about any ticket dependencies, populate the dependencies field with the ticket numbers and/or minimum Sage version.

Only the devel repository has branches, so the buildbot is unable to apply and try out patches to extcode/scripts/etc.

Patch Status

Patches can have the following status:
