Where c0f85061c7d3 & 71a8786c3815 are examples of the last working changesets in gecko and cd3e9359fd64 & e8f6bdf8db3d are examples of the first broken changeset in gecko. Next, open the link and check if the regressing changeset was from a b2g-inbound merge. If it was, then you'll want to bisect even further using b2g-inbound tinderbox builds to find the exact regressing changeset.
At this point, you'll have all of the data you need to present a regression window on a bug.Here's an example of a presentation of a Gecko regression window: Last Working Environmental Variables:Device: BuriBuildID: 20140122004001Gaia: 744fb691c2b2a25a07c5d19fabf5748ae9aba4d9Gecko: 71a8786c3815Version: 28.0a2Base Image: V1.2-device.cfg First Broken Environmental Variables:Device: Buri BuildID: 20140123004001Gaia: 6fbeac2415f07f10de181f0877ddf67ee299b885Gecko: e8f6bdf8db3dVersion: 28.0a2Base Image: V1.2-device.cfg Last Working Gaia/First Broken Gecko: Issue DOES ReproduceGaia: 744fb691c2b2a25a07c5d19fabf5748ae9aba4d9Gecko: e8f6bdf8db3d First Broken Gaia/Last Working Gecko: Issue Does NOT ReproduceGaia: 6fbeac2415f07f10de181f0877ddf67ee299b885Gecko: 71a8786c3815 Push Log: http://hg.mozilla.org/releases/mozilla-aurora/pushloghtml?fromchange=71a8786c3815&tochange=e8f6bdf8db3d Here's an example of a presentation of a Gaia regression window: Last Working Environmental Variables:Device: BuriBuildID: 20140215095648Gaia: 8ac5dc6b76709e742cb923c58d1f4b415b3e08fbGecko: 9394396013a8Version: 30.0a1Firmware Version: v1.2-device.cfg First Broken Environmental Variables:Device: BuriBuildID: 20140215100248Gaia: f75b9dac351c0676f0fc696fa36330933985ed36Gecko: 4ebfb26de52cVersion: 30.0a1Firmware Version: v1.2-device.cfg Last Working Gaia/First Broken Gecko: Issue does NOT reproduceGaia: 8ac5dc6b76709e742cb923c58d1f4b415b3e08fbGecko: 4ebfb26de52c First Broken Gaia/Last Working Gecko: Issue DOES reproduceGaia: f75b9dac351c0676f0fc696fa36330933985ed36Gecko: 9394396013a8 Push Log: https://github.com/mozilla-b2g/gaia/compare/8ac5dc6b76709e742cb923c58d1f4b415b3e08fb...f75b9dac351c0676f0fc696fa36330933985ed36
