ITK Release 4/What Developers Must Do To Contribute to the Users Migration Guide
From KitwarePublic
Jump to navigationJump to search
Overview
What Information Must Be Captured
- Git hash of the ITKv4 commit that changed the API
- Migration guide page describing the justification for the change
- Along the lines of:
- Migration Users Guide
- Git hash of the Sequestered Applications commit that fixed the app to build with the new API
Proposed Procedures
General Ideas
- Gerrit review checklist
- Step that asks "Does this patch change the API"
- If so, have the changes been documented in the migration guide
- Only accept if documented
- Documentation should include:
- Names of files that change API
- English explanation of changes
- Code example of conversion from old API to new API
- Some parts of documentation could be auto-generated
- Extract English explanation from git commit
- Find conversion examples in diff of tests
- Names of files generated from git commits as well
- Some sort of interface where automatic guesses for each migration component are auto-generated and developer can make changes to auto-generated results.
- Maybe an addition to gerrit (how much gerrit editing can we do?)
- If not, some sort of html form that is auto-populated from git and can be changed manually
Specific Proposals
- Git commit messages
- If changes api, commit message must start with API - ...
- API changes must include sections:
- RATIONAL: english explanation of what the change is and why it was made
- Possibly include OLD and NEW sections for sample code
- Gerrit post-review
- Once change is fully reviewed and ready to be committed to master, developer must make a post to phpBB with full commit details
- Forum post could be automatically populated by pulling in commit messages and/or review discussion from gerrit
- Would then need to be manually edited by developer before final merge to master allowed
