Software Update:GeneratingSnippetsAndPartialsForReleases

For releases of Firefox and Thunderbird, the Build & Release team at Mozilla Corp uses a program called patcher2. This document describes the basics of how to use it.

Overview

How Firefox/Thunderbird updates are tested

We use four update channels for Firefox & Thunderbird releases. The two channels that end users see are

• beta - default channel for the releases 2.0a1, 2.0b1, and up to the last 2.0 beta
• release - default channel for the first release candidate for 2.0. The vast majority of people are on this channel.

Then there are

• betatest - mainly QA testing of updates, pointing to the ftp server, to check that they apply properly, the UI works etc etc
• releasetest - mainly QA testing of updates, pointing to download.m.o (bouncer), to make sure everything is available to end users when the release is imminent
