[llvm-dev] RFC: Move the test-suite LLVM project to GitHub?

[John Criswell via llvm-dev]

Dear Chandler,

First, can you articulate why you want to move the test suite to 
Github?  Is it taking up too much space, or is there some other problem 
that you're trying to solve?  I think you clearly explain why moving the 
revision history isn't necessary, but it's not clear to me what problem 
you are trying to solve.

Second, if we move the revision history to Github, it would be nice to 
archive the existing Subversion history somewhere (e.g., leave it on 
llvm.org but disable commit access to it).  The test suite has been used 
in numerous research papers, so keeping the revision history around is 
good practice.  We should only delete the Subversion revision history if 
keeping it around is just too onerous.

Third, I assume your plan is to continue to track changes on Github. Is 
that correct?

As long as there's a good reason to do it and the existing Subversion 
history isn't deleted, I don't see a problem with the change.

Regards,

John Criswell
