'''Hard Code Freeze''' -
last day when we accept fixes on High priority bugs. When we reach hard code freeze, we should have 0 critical bugs and no more than 5 high priority bugs open. If we have more high priority bugs, or even one critical, we move hard code freeze unless the condition is met. When we meet this condition, and hard code freeze is announced, then it is being announced with information about stable branch created and Release Candidate is created. It is the time when master opens for next release changes, including features. Critical bugs, if found after this day, cause the following procedure: |+|

Revision as of 23:24, 17 December 2015
Hard Code Freeze (HCF) is a quality-based milestone in the Fuel release cycle that marks availability of the first release candidate (RC1), after which only Critical bug fixes are allowed in the release branch.
- Swarm (fuel-qa/system_tests) pass rate is above 90%
- Less than 5 open High bugs, no open Critical bugs
- Less than 30 High and less than 10 Critical bugs were closed during the previous week
If HCF entry criteria are not met on schedule, HCF should be postponed.
If Critical bugs are found in an RC, more RCs are produced iteratively until QA team confirms that the latest RC is suitable for a stable release.
Just as with Soft Code Freeze, commits to the stable branch during and after HCF must follow the backporting process.
