Revision option for prepare about craft

[tonyo]

What would be the semantics of prepare with rev provided?
Do you want to create the release branch based on that revision?

[Jean85]

Yes, exactly. I needed that today here: getsentry/sentry-symfony#283
Master was already ahead (3.3.x, new minor version) and I needed to release a patch (3.2.1) using
8a176d7 as a revision, before merging master in that branch.

craft release --rev is able to do that, but I do not have enough permission, so @HazAT had to do that for me, without my help and review beforehand with craft prepare.

Just to clarify: as far as I understand, the agreement here was that release would be run by @HazAT anyway, so adding new features to prepare will not really fix it.

Regarding the feature itself, generally I agree that it'd make sense to add it.
To agree on the semantics, craft prepare --rev REV VERSION will do the following:

• Checkout REV
• Check that the changelog for the new version (VERSION) is there (if the changelog check is configured)
• Create a new release branch
• Run pre-release command (which is user-configured, it usually bumps the version in some files, and you can run some additional checks there) and commit the changes
• Push the release branch

Does it sound good?

[Jean85]

Yes, absolutely!
