Add support for inspection using ironic-inspector

2015-09-07T16:22:54+00:00

Adds a new module ironic_python_agent.inspector and new entry point
for extensions, which will allow vendor-specific inspection.

Inspection is run on service start up just before the lookup.
Due to this early start, and due to the fact we don't even know
MAC address of nodes on inspection (to say nothing about IP addresses),
exception handling is a bit different from other agent features:
we try hard not to error out until we send at least something to inspector.

Load Hardware Managers at runtime

2015-08-28T21:15:31+00:00

Hardware managers should load at runtime. This will ensure the agent is
ready to respond to API calls before it begins heartbeating. Also, it
means in case of a syntax or other error in a HardwareManager, the agent
will crash before it heartbeats, which is better than it working until a
hardware manager method is needed.

library.

Allow use of multiple simultaneous HW managers

2015-01-08T23:15:13+00:00

Currently we pick the most specific manager and use it. Instead, call
each method on each hardware manager in priority order, and consider the
call successful if the method exists and doesn't throw
IncompatibleHardwareMethodError.

This is an API breaking change for anyone with out-of-tree
HardwareManagers.

Add standalone mode for IPA

2014-12-17T01:59:29+00:00

This allows a developer to run IPA without an Ironic API. This can
be useful for testing (especially functional testing) or testing
integration of things like hardware managers.

Force heartbeat immediately after async command completes

2014-10-13T18:09:09+00:00

This change passes the agent object into extensions, such that
they may call agent methods as needed. It also causes async
commands to force a heartbeat immediately after completing the
command. This allows Ironic to get a heartbeat and continue
work as quickly as possible, while also allowing deployers to
configure Ironic (agent) to heartbeat less often.

Use poll instead of threading.Event in heartbeat thread

2014-10-13T17:50:08+00:00

poll() does not rely on absolute time.
This fixes an issue where the system clock may be changed, and
the heartbeat thread would stop heartbeating.

This also gives us flexibility to force a heartbeat in a later
change.

Fix exception that is not properly raised

2014-09-10T21:53:37+00:00

This commit fixes an exception that was not properly raised, and
also makes the exception more relevant.

This also fixes an outstanding bug where, if the agent
was not associated with a node, get_node_uuid() would fail in an
unexpected manner.
