Turds from failed rebases before can cause errors:

error: Untracked working tree file 'WebCore/storage/SQLTransactionClient.cpp' would be overwritten by merge.
could not detach HEAD
rebase refs/remotes/trunk: command returned error: 1

Rejecting patch 34895 from commit-queue.  This patch will require manual commit.

Doing 'git clean -f' is really scary, but we need to do it to make the bot run nice...

commit-queue is scary.  Let loose the dogs of war!  git clean -f --for-realz-now
Comment 2 Eric Seidel (no email) 2009-09-01 16:22:15 PDT 
LayoutTests getting left around are particularly bad.  When running the commit-queue from an SVN checkout any failed patch will leave any added files around.  If those added files were layout tests, all patches after that one will start failing!

Just saw this again with https://bugs.webkit.org/show_bug.cgi?id=32995#c5
Comment 4 Eric Seidel (no email) 2009-12-29 11:10:55 PST 
This is the worst bug affecting the commit-queue now that it's running from an SVN checkout.  I'll have to bump this up on my priority list.
Comment 5 Adam Barth 2009-12-29 11:49:14 PST 
How are you going to run git clean -f from an SVN checkout?
Comment 6 Eric Seidel (no email) 2009-12-30 09:31:12 PST 
A possibly related failure:

Comment 7 Kenneth Russell 2010-01-01 11:30:12 PST 
How about "svn revert -R ." from the root of the tree?
Comment 8 Eric Seidel (no email) 2010-01-03 16:26:05 PST 
This has caused enough commit-queue failures that I'm going to move the commit-queue back to using Git for now.  I'll bump this bug up on my list of bugs to fix.
Comment 9 Eric Seidel (no email) 2010-01-03 17:49:14 PST 
@kbr: svn revert -R is already done.  git clean -f actually deletes untracked files.  We'll ahve to write an SVN equivalent.
Comment 10 Kenneth Russell 2010-01-04 08:00:54 PST 
Would this do it?

svn status | grep ^\? | awk '{print $2}' | xargs rm -rf
Comment 11 Eric Seidel (no email) 2010-01-04 13:23:00 PST 
Yes.  We even have code like this already in scm.py, it just needs to all be wired together into some sort of remove_untracked_files() method on SCM implementations.

For an example of status-parsing logic see run_status_and_extract_filenames  and callers:
