Subversive Ramp Down Helios
Subversive ramp down plan for Helios
Ramp Down Details
Typically the last week of a Milestone is for testing, and fixing only regressions and P1 or blocking defects. For milestones, the component lead (or delegate) is enough to review and approve a bug.
For M6, we plan to be API complete, so there will not be any more breaking API changes or unsolicited API change requests accepted.
For M7, we plan to be functionally complete. We will accept API changes only if regressions are involved, or serious issues need to be addressed. Only non-breaking API changes are accepted, and require review by the component lead and one additional committer.
After M7, the remaining Release Candidates are (only) for fixing bugs, or fixing release required items (such as version numbers, licensing, etc.).
After M7, production of release candidates starts. Additional RCs will be produced every week. After the first RC is produced, the time for general functional improvements is long past. The following describes the types of bugs that would be appropriate:
- A regression
- A P1 or P2 bug, one that is blocking or critical, and some cases of major severities.
- Documentation files are exceptions to the normal PMC required review, since there is little chance of that breaking anything, though it is still expected to be complete by M6, and remaining work to be only documentation fixes (that is, no refactoring of plugins, build changes, etc, without PMC review and approval).
- In addition to a bug meeting the above priority/severity conditions, there should be a simple, safe, well understood fix that is well isolated from effecting other components, that doesn't affect API or adopters, that has been well reviewed and well tested.
- As each Release Candidate passes, the criteria for weighing the benefit-to-risk ratio criteria gets higher and higher, and as such requires a larger number of committers and PMC members to review.
- May 7th, M7 produced
After May 7, API changes or functional enhancements should no longer happen. For plain bugfixes, review is optional although it is encouraged for any bug beyond real simple changes. All checkins except simple [cleanup] should be associated with a corresponding bugzilla item.
- May 21st, RC1 produced
After the May 21, all checkins must be associated with a bugzilla item describing the change - even simple cleanups must be described and linked with the checkin comment through a  bug number. Besides the fix author, at least 1 additional committer must also review and vote +1 on bugzilla for each change, although the review may also happen after-the-fact to ensure smooth operation: fixes can be committed provided that the review and voting happens afterwards.
- May 28th, RC2 produced
After May 28, at least 1 additional committer must review and approve each patch on bugzilla before it can be committed. Approvals after the fact can only happen in case of a must-fix-emergency where no reviewer is reachable in time.
- June 4th, RC3 produced
After June 4, at least 2 additional committers must agree in a vote after reviewing the bug for appropriateness and risk before it can be committed.
- June 11th, RC4 produced
After June 11, all available committers must also review and agree in a vote after reviewing the bug for appropriateness and risk before it can be committed.
