[Qemu-devel] [PATCH v6 20/29] vhost-user-test: Drop dependence on global_qtest |
Date: |
Fri, 1 Sep 2017 13:03:31 -0500 |
Managing parallel connections to two different monitors via
the implicit global_qtest makes it hard to copy-and-paste code
to tests that are not aware of the implicit state. Now that
libqos is fully-explicit, it is easy to expand the rest of
vhost-user-test to also use explicit state everywhere.
We can assert that the conversion is correct by checking that
global_qtest remains NULL throughout the test (a later patch
that changes global_qtest to not be a public global variable
will drop the assertions).
