[llvm-dev] [Github] RFC: linear history vs merge commits

[Tom Stellard via llvm-dev]

Hi,

As part of the migration of LLVM's source code to github, we need to update
our developer policy with instructions about how to interact with the new git
repository.  There are a lot of different topics we will need to discuss, but
I would like to start by initiating a discussion about our merge commit
policy.  Should we:

1. Disallow merge commits and enforce a linear history by requiring a
   rebase before push.

2. Allow merge commits.

3. Require merge commits and disallow rebase before push.

I'm going to propose that if we cannot reach a consensus that we
adopt policy #1, because this is essentially what we have now
with SVN.

What does everyone think?

Thanks,
Tom
