The existing doc says ssl_assert_hostname = False, should it be = None?

The existing doc says ssl_assert_hostname = False, should it be = None?

In the existing doc, comment says # hostname verification disabled. Therefore ssl_assert_hostname = False is correct.

• ssl_assert_hostname = False
  no verification is done.
• ssl_assert_hostname = None
  verification is done with server_hostname (It is equivalent to not setting ssl_assert_hostname)

Are integration test failures expected?

Are integration test failures expected?

Verified that failing tests aren't related to this PR; they're YAML tests. Currently working on fixing them.
