From a67bc41d6bc25974e6aa6d864d5265d07c890413 Mon Sep 17 00:00:00 2001 From: Andrew Tridgell Date: Tue, 10 Mar 2009 15:12:48 +1100 Subject: added a test that triggers a bug in the Samba3 notify code The Samba3 internal notify code doesn't work correctly when there is more than one tree connect to the same smbd process. This change to the RAW-NOTIFY test triggers the bug. --- source4/torture/raw/notify.c | 169 +++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 169 insertions(+) (limited to 'source4') diff --git a/source4/torture/raw/notify.c b/source4/torture/raw/notify.c index 3ffc58dbe6..c92170cf61 100644 --- a/source4/torture/raw/notify.c +++ b/source4/torture/raw/notify.c @@ -1429,6 +1429,174 @@ done: return ret;
