Cannot rewrite branch(es) with a dirty working directory

Hi All,

I get a spurious: "Cannot rewrite branch(es) with a dirty working directory." trying to filter-branch in a clean git repo (having done a reset). The error disappears when I do git status.

Log of the shell commands: bash:jamesb:xl-cbga-20:33083> mkdir org.eclipse.cdt.core.linux.ia64 bash:jamesb:xl-cbga-20:33084> cp -r ../../../CDT_HEAD_GIT/org.eclipse.cdt/.git org.eclipse.cdt.core.linux.ia64/ bash:jamesb:xl-cbga-20:33085> cd org.eclipse.cdt.core.linux.ia64/ mbash:jamesb:xl-cbga-20:33086> git reset --hard Checking out files: 100% (11879/11879), done. HEAD is now at a03d454 Build against a local mirror of the 3.7 p2 repo bash:jamesb:xl-cbga-20:33087> git filter-branch --subdirectory-filter core/org.eclipse.cdt.core.linux.ia64 -- master Cannot rewrite branch(es) with a dirty working directory. bash:jamesb:xl-cbga-20:33088> git status # On branch master nothing to commit (working directory clean) bash:jamesb:xl-cbga-20:33089> git filter-branch --subdirectory-filter core/org.eclipse.cdt.core.linux.ia64 -- master Rewrite d7092b12c93925f6f7c4725a5abc72e55650621c (16/16) Ref 'refs/heads/master' was rewritten bash:jamesb:xl-cbga-20:33090> git --version git version 1.7.3.2

Is there a particular reason why filter-branch thinks the tree is dirty, and status magically fixes this?

Cheers, James
