Hi Stucki,

I agree with all of that and it looks pretty good!

What is still missing is an important part: What *would* be the new name
of our repository?

There is a very confusing and not concluding brainstorming document here:


We have thought that the TYPO3v4's new name in GIT could be:


But then lots of questions arose: Couldn't it be "Distributions"? What
about CMS-Extensions? Are they also Packages? etc etc..

This "thingy" has to be decided first, and requires some interaction
with the Flow/Neos team, because their current names aren't consistent
too (i.e. FLOW3/Packages/TYPO3.FLOW3.git). Also we should not forget
that we want to include the "upstream fluid" directly in TYPO3 CMS at
some point, which is currently FLOW3/Packages/TYPO3.Fluid.git.

Complex topic.. It should be finished in a small team which knows the v4
and the Flow side of the requirements and has some foresight.

> include this command during the setup.
> * Prepare the history of submodules in a branch which also has the
> namespace problems fixed. Afterwards, merge this branch. (Thomas
> Maroschik is already working on this.)
> * Renaming of the repository:
> a) Just delete the remote & add a new one
> b) $ git remote set-url origin "<new-url>"
> If we do it like this we have a complex history where submodules are
> switched on and off, which is not always easy to manage. However, as a
> benefit, we keep all SHA's and don't need a single history rewrite.
