Unfortunately, python being python, ansible may elect to install under a
different python runtime than confluent.
In such a case, hope that the ansible python can work.
Remove eventlet as a hard requirement, as
that is unlikely to be in ansible python.
This leaves msgpack, which is unavoidable, for now. But if it's in ansible python,
it's fine.
When a session is being discarded, it
may inadvertently hold onto logonwaiters.
The IPMI session may be reused, but the context is new and those
dead contexts can consume memory unreasonably.
If 123abc-abc123 were attempted, it would produce
a strange error
when it encounters a string compare to number.
Detect the scenario and treat it like similar situations.
Some plays expect the
inventory from /etc/ansible, detect
if that inventory *could* apply, use if it can.
ansible users generally anticipate leveraging the implicit '.' in the role
path,
chdir to meet that expectation.
'become' in the play without 'become_user' can upset ansible runtime.
Since we are already root, we will just ignore the implicit 'become', since we already
match that behavior.
Provide for applications
where only a small subset of collective
members should be
considered to count
toward whether the collective
can proceed.
Commonly, 'service' nodes may
be numerous to do work, but may all want to go offline
during a maintenance window.
While servicing an enrollment,
there's a window for a collective
member to be 'defined' but not
yet active, meaning quorum may transiently be lost as multiple enrollments progress.
Serialize enrollments by holding the enrollment process open.
Also, there is a chance that a transient transfer error may occur during loading
of the DB. In such a case, restart
the connection rather thn aborting.
Added 2 new function to check if the custom yaml file exists - /etc/confluent/authorize.yaml - and one to update the _allowbyrole and _deniedbyrole vars accordingly.
The open file handle as implemented
could not pass to the subprocess.
Rather than figure out how to open
and pass the filehandle,
simply let the subprocess
independently open the file
if it isn't passed.
