 When is the repository write accessible?

Hi,

this is what I'm planning to suggest to the Eclipse Webmaster:
comments/resistance?

Let's get specific.

- We'd like to migrate as soon as possible.
- Due to the uncertain import situation (1) it seems cleaner to only import HEAD to git and use the old CVS repository in case we need to access the history. Furthermore, I still like the idea of getting rid of historical ballast.
- We need *six* repositories:
 - org.eclipse.xtext.git
 - org.eclipse.xtext.releng.git
- org.eclipse.emf.mwe.git
- org.eclipse.emf.mwe.releng.git
- org.eclipse.xpand.git
- org.eclipse.xpand.releng.git

ok, then let's care about them all at once.


(warum muss da überall das 'git' suffix dran sein?)

it's a common pattern to show off that a certain directory is a git repository. See also: http://git.kernel.org/ and http://git.eclipse.org/


- They will be fed from
- http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.tmf/org.eclipse.xtext/?root=Modeling_Project - http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.tmf/org.eclipse.xtext.releng/?root=Modeling_Project

usw.


- We would like to use CVS and git in parallel for some time. By parallel I mean write access to git and CVS. It will be our responsibility to keep CVS and git synchronized - we'll probably do so by applying the same patch to both repositories. I can also think of applying all changes to git and only the critical bugfixes to CVS. This is because we haven't migrated our build infrastructure to git yet and we need to have a writable repository + integration build at all times. As soon as the build and working with git seems reliable, we'll ask to turn the CVS repository read-only.

Yesterday we discussed to have the git repository as a playground in order to get the builds up and running while the CVS remains the production repository. Then at some point when we are comfortable with the new environment (and the builds are running) we could replace the git repos with the latest from CVS head. Why don't you want to do this anymore?
Yesterday we were discussing a git server which would be hosted by itemis and purely designated to be a playground.... anyway, we can treat it the same for the git repository at eclipse.org.

If we (re-)import CVS HEAD at some later time, we should make sure to include at least all revisions since the Helios release. It think it's valuable to have the source code available in git as it was released with Helios since many bug reports and support requests we will be based on this version. Having it tagged in git would make it trivial to switch one's workspace to this version.

regards,
 Moritz
