[Development] When is Qt 4.8 in Gerrit? (Was: Qt Commercial 4.8.0 release delta to LGPL version)

[shane.kearns at accenture.com]

With both 4.8 and 5.0 in gerrit, how should we do back/forward porting of bug fixes between repositories?
Should the change author cherry-pick, resolve conflicts, and submit a change to the other repository?

Or will a fix accepted to 4.8 be applied to 5.x without usually needing further involvement of the author?
(like the 4.7->4.8 merges, although it probably can't be done with a git merge)

I'd assume the author knows best how to resolve conflicts, but it raises the bar for entry.

My view is the workflow should look like this:

1. author submits change to the version they normally work on (4.8 or 5.0)
2. code review happens, change accepted
3. CI happens, change integrated
4. author cherry-picks to the other repository, resolving any conflicts & test on their preferred platform
5. code review - if there weren't conflicts then this should often be a formality by the previous approvers
6. CI happens - this will pick up if the change isn't compatible with the new/old architecture. (if the reviewers missed it)

My experience is that cherry-picking QtCore and QtNetwork changes is usually OK, except for autotests which conflict due to path changes
