I'll report back to you on my success or not. -Alfred On 12/15/12 5:22 AM, Ulrich Spörlein wrote: > Bad news everyone, > > tl;dr The git mirror of the source repository needs to be re-rolled to > make the conversion deterministically repeatable, this will change > pretty much all git commit hashes. > > The re-roll will be done January 15, 2013. > > Not affected are the ports and doc repositories, nor is the svn_head > (for use with git-svn) affected. > > > Background > > The converter (svn2git) was handing commits and objects to git's > fast-import in arbitrary order, this makes merge commits have an > arbitrary order of their parent commits and thus these merge commits > have changing commit hashes for each converter run. > > This has been fixed, but requires us to move all the branches over to > this deterministic scheme, which will change all their commit hashes. > None of the contents of these commits change, so rebasing/remerging your > work into these branches is possible without running into any merge > conflicts. > > > We need your help > > A goal of these conversions is to have them repeatable by you (yes, > you!), so the correctness of the conversion can be verified.
