TPTP ramp down policy on Helios
TPTP Ramp down for Helios
Typically, the last week of a milestone is for testing, and only fixing regressions and P1 or blocking defects. For milestones, the Project Lead (or delegate) is enough to review and approve a bug (refer to TPTP project matrix for Project leads).
For M7 we plan to be functionally, and API complete and the remaining Release Candidates are for fixing bugs, or release required items (such as version numbers, licensing, copyright, etc.).
Starting with RC1, we expect each Project Lead (or delegate) to review and verify their teams' bugs.
After the first RC is produced, other RCs will be produced weekly, if needed, corresponding to the Helios RC drop schedule and dropped to the Helios staging update site.
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 severity.
- Documentation and PII 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 plug-ins, 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, benefit-to-risk ratio criteria is higher requiring PMC approval.
- April 16
- In preparation for delivering a translatable release and closing on the new function in the time line we had planned for, we had made sure that all of the new properties strings used in the UI by these enhancements are checked in before April 16. New strings generated after this time will be reviewed and approved using the must-fix approval process.
- May 18, RC1 produced
- After May 18, besides the normal component team review, at least 1 PMC member must also review and vote +1 after reviewing the bug for appropriateness and risk.
- May 25, RC2 produced, if necessary
- June 1, RC3 produced, if necessary
- June 8, RC4 produced, if necessary
- June 15
- Do zip, TPTP and Helios update site, and website preparations
- June 23
