Python 2.6.6 has the same bug as Python 2.7, where HTTP authentication just stops working, but does not have the setter method to clear the retry counter. Work around by setting the field directly if it exists. Change-Id: I6a742e606bb7750dc66c33fc7c5d1310541db2c8 Signed-off-by: Shawn O. Pearce <sop@google.com>
