Subject Re: [DISCUSS] git branching model
Date Sat, 13 Feb 2016 17:35:08 GMT
A couple thoughts...

Push release branches. This would help avoid the confusion we had with the
0.5.0 release. It would be clear that bug fixes being made for the current
release would need to be pushed to both master and the release branch. It
would also allow master to continue receiving commits that will not be
incorporated into the current release. Using branches (in addition to tags)
would make it easier if multiple folks are committing bug fixes as was the
case with 0.5.0. It may even make sense to keep the release branch around
for awhile (maybe X subsequent releases). This would also provide a
convenient place to branch from if we needed a quick bugfix release like we
did in 0.4.1.

Moving forward when we start working some 1.X features I would like to see
essentially two masters (though we can name them whatever we want).
Continue with the same model (RTC) as we do currently but pushing commits
to either the 0.X master, the 1.X master, or both. We would continue to
support both master branches until we've stopped support for the 0.X
baseline whenever we decide that will be.
