- don't create a new connection during reset if no existing connection
exists
- strip off last hop in connection stack if PlayContext.become is True.
- log a debug message if reset cannot find an existing connection
It used to be set by on_action_run() from task_vars, but this doesn't
work for meta: reset_connection. That meant MITOGEN_CPU_COUNT>1 would
pick the wrong mux to reset the connection on.
Move all details of broker/router setup out of connection.py, instead
deferring it to a WorkerModel class exported by process.py via
get_worker_model(). The running strategy can override the configured
worker model via _get_worker_model().
ClassicWorkerModel is installed by default, which implements the
extension's existing process model.
Add optional support for the third party setproctitle module, so
children have pretty names in ps output.
Add optional support for per-CPU multiplexers to classic runs.
The idea behind transport=smart is to select between paramiko and
OpenSSH given the availability of connection multiplexing and/or OSX
kernel bugs. We need to make no such choice.
Since Python 2.4 fork is so defective, we must use subprocesses for
mitogen_task_isolation=fork. This has plenty of upside, since the long
term goal is to dump forking altogether. This allows a gentle
introduction of its replacement.
This refactors connection.py to pull the two huge dict-building
functions out into new transport_transport_config.PlayContextSpec and
MitogenViaSpec classes, leaving a lot more room to breath in both files
to figure out exactly how connection configuration should work.
The changes made in 1f21a30 / 3d58832 are updated or completely removed,
the original change was misguided, in a bid to fix connection delegation
taking variables from the wrong place when delegate_to was active.
The Python path no longer defaults to '/usr/bin/python', this does not
appear to be Ansible's normal behaviour. This has changed several times,
so it may have to change again, and it may cause breakage after release.
Connection delegation respects the c.DEFAULT_REMOTE_USER whereas the
previous version simply tried to fetch whatever was in the
'ansible_user' hostvar. Many more connection delegation variables closer
match vanilla's handling, but this still requires more work. Some of the
variables need access to the command line, and upstream are in the
process of changing all that stuff around.
(Pull #377)
Changes:
- additional_parameters -> extra_args
- Merge with kubectl changes from dmw branch
- Update docs
- Remove unused username class member
- Avoid mutable kubectl_args class member
- Use six.iteritems
This change allows the kubectl connector to support the same options as
Ansible's original connector.
The playbook sample comes with an example of a pod containing two containers
and checking that moving from one container to another, the version of Python
changes as expected.
Reverts 49736b3a, large file copies can't avoid the RTT.
The parent stack must be blocked while FileService progresses, as unlike
the small file path, it does not make a snapshot of the (possibly
temporary) file passed by the action plug-in. So we need to keep that
file alive while the service runs.
Add a new integration test and a new soak test to cover both.
