Sorry for this trouble,
I repaired subversion repository with rollback.
It breaks subversion local working directory.
If you update your subversion repository of MRI between
and 2012-11-01T14:30Z, the repository can’t update anymore.
Please re-checkout the repository.
If you use git-svn, it can be fixed by
git svn reset -r 37408.
The brekage is caused by my wrong tagging of v2_0_0_preview1 (old
which introduces large changeset and causes git-svn mad.
So I repaired it with dump the repository with svnadmin dump 0:37408 and
The rollback breaks repositories synced with the wrong repository.
Sorry for your incovenience and thank you for your support
