Status

• 12/4/08 - Draft, to be reviewed by PMC
• 12/5/08 - Updated some dates to increase T&F phases for M5, M6, and M7 based on feedback

Purpose

This document defines a schedule and set of ramp-down policies for DTP 1.7 (Galileo). The goal is to ensure that DTP stability and completeness converges on the 1.7 release dates, while allowing mechanisms for changes as necessary.

Schedule

• 1.7M4 - December 17, 2008 (publicly available 1/12/09)
• 1.7M5 - February 3, 2009 (publicly available 2/16/09)
• 1.7M6 - March 16, 2009 (publicly available 3/23/09) (API Freeze)
• 1.7M7 - May 7, 2009 (publicly available 5/11/09) (Feature Freeze)
• 1.7RC1 - May 18, 2009
• 1.7RC2 - May 25, 2009
• 1.7RC3 - June 1, 2009
• 1.7RC4 - June 8, 2009
• 1.7RC5 - June 15, 2009
• 1.7 Release - June 26, 2009
  • Galileo release train as a +1 project. Those dates are [here].

Builds Reminder

• Nightly builds take place from Monday to Thursday. Integration builds takes place on Friday.
• During a test phase, there are no builds. We take the build before the test phase and test it. If we run across extreme issues, we will respin and retest.
• During the test/fix phase for the RCs, we will do regular daily builds. Once we are in the test/fix phase, where PMC approvals are needed, we will not build nightly, but will build as needed (5/11 and beyond).
• On Push days, we will take the Monday Shanghai build (which is our Sunday at 2pm PST) and if it's good, we will push it to the update site that Monday evening (SH Tuesday a.m.). If things are not good, we will fix the issues and respin the build, taking the respun build and pushing it to the update site.
• DTP builds will take place at 5am (Shanghai time).
• In general, builds occur Mon - Fri at 2pm Shanghai time, which is equivalent to Sun - Thu 2pm PST.
• DTP committers should refrain from updating map files for +/- 30 minutes around the start of the build, to avoid version inconsistencies in the map file set.
• See the Build Transition page for additional details about regular DTP builds

Integration Builds

Starting on Friday, November 21, and continuing through Tuesday, May 12, the latest available DTP 1.7 integration build (done each Friday, as noted above) will be tested for promotion. If no substantial defects are found, then the build will be promoted.

Testing & Fix Pass

A period of intensive testing, including bug fixes based on the approval policies described below. Nightly builds will be produced during this period as necessary to make bug fixes available to the DTP community.
