I just came across this issue where if an IntegrityError is raised on
session.commit() then the offending object that caused the error is
automatically removed from the session. If the object is a child
object is related to parent object and the child object is in
session.new then it is removed

its removed when you say rollback().any pending add()s are
As always, thanks for the excellent and thorough response.
It does seem that if the offending object is in session.new when the
commit() fails it is removed from the session without me doing a
rollback(). e.g:
u = User()
session.add(u)
session.commit()
(IntegrityError) user.name may not be NULL
