Lessons Learned from the move to GitHub

Repository Conversion

• Overall that went well
• The contrib repositories should have been split into smaller chunks. We should probably split them and archive the old repository. #56049
• There are some user repositories left that are dead. We should set a deadline, send a mail to the list and remove all of them after the deadline. ​https://lists.macports.org/pipermail/macports-dev/2018-March/037639.html

Pull Requests

• The bot is very helpful, and so is the GitHub UI for merging things easily without having to use a command line.
• pmetzger is doing a great job in keeping the number of open pull requests down
• Only members can be assigned to pull requests in GitHub, but we have non-member maintainers. We should change the bot to assign the PRs if the maintainers are members, but keep the current behavior to also support the use case for external maintainers.
• We may have a bit of a hot trigger finger when merging pull requests, but that does not seem to have caused problems so far, so it's likely a non-issue.
• We can now request reviews before merging changes and are using this quite a bit on base and infrastructure repositories.

GitHub handles in Portfiles #56050

• A lot of maintainers have not added their GitHub handle to Portfiles, even regular contributors.
• We could use the Trac database to compute a match and automate the task.
• We should probably make Trac always use email addresses from GitHub and remove the ability to change email addresses in Trac.

Trac

• trac-github could monitor pull requests mentioning tickets and post a comment with a link to the pull requests. (​https://github.com/trac-hacks/trac-github/issues/130, some code may be available in ​https://github.com/trac-hacks/trac-github/issues/75)
• Trac's GitHub integration is nice so far, the unified login works well.
• The trac landing pages are not very good; some user experience improvements could be done. We'll defer discussion to the UX session that's planned for tomorrow.
• Should Trac send a periodic digest for new open tickets to macports-dev? We could use ​https://trac-hacks.org/ticket/8802 for that.
