HEADS UP: FreeBSD git mirrors demoted to beta status, need your help

[Ulrich Spörlein]

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. There are
also no backups of the conversion runs, as they should be repeatable
anyway.

We need 2-3 volunteers to run these conversions themselves and verify
that the produced commit hashes match the published ones. The necessary
steps to do this are documented on the Wiki under

   http://wiki.freebsd.org/GitWorkflow#History

Please send me your output of git show-ref in a private mail, thanks.

Cheers,
Uli

PS: This re-roll has nothing to do with the recent security incident.
