Subject: Add another torture test inspired by George @ Apple.
X-Git-Url: http://git.samba.org/samba.git/?p=jra%2Fsamba%2F.git;a=commitdiff_plain;h=bcadb77c18f9ed9be22762871617f1a12294e88c;hp=b934f509ed222eb49e8b24ca111361e563434646

Add another torture test inspired by George @ Apple.
Inside a directory, keep a file open and then renaming
the directory should fail with ACCESS_DENIED. This
is connected to the test case where the close was
failing due to a delayed write on a file not being
able to succeed when Samba allowed the containing
directory to be renamed.

I will fix this in the server shortly (this should be done
across connections also but with will be very hard
in Samba - would need a full scan of the open file
db on every directory rename) - so I will fix for
the local case first (scanning local file opens
inside an smbd is cheap).

Jeremy.
