Contexts may now have transaction constraints set on them to be enforced
|
|
by the revision plugin in Neutron for generalized compare-and-swap updates.
|
|
Calling ``set_transaction_constraint`` on the context before performing a
|
|
resource mutation will setup the constraint. This is also exposed to users
|
|
via the HTTP API with ``if-match`` headers and the API layer sets the
|
|
constraint on the context.
