Earlier commit moved Stream.routes attribute into a private map
belonging to RouteMonitor, to make upgrades smoother. This adds a new
accessor method to RouteMonitor.
(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.
When Ansible abnormally shuts down, the broker begins
force-disconnecting every context, including those for which connection
is currently in-progress.
When that happens, .call(init_child) throws ChannelError, and that needs
returned back to the worker, assuming the worker still even exists.
This solution is incomplete: with sick nodes, it's also possible the
worker died naturally, and so the worker should perhaps respond by
retrying the connection.
Previously, the unhandled ChannelError would spam the console when e.g.
fork() began returning EAGAIN.
The connection multiplexer can expect to not be scheduled at least until
every $forks worker processes has attempted a connection, so the backlog
must be able to hold every worker.
* Always enable the faulthandler module in the top-level process if it
is available.
* Make MITOGEN_DUMP_THREAD_STACKS interval configurable, to better
handle larger runs.
* Add docs subsection on diagnosing hangs.

Calls to connect.put_file() where the file is sufficiently small enough
to fit in a single RPC proceed without waiting for an RPC response. If
the write fails the target context will log an exception, and any
subsequent step depending on the written file will fail.
I verified every built-in action plugin for file transfer calls, and
they all depend on the transferred file in the following step, so this
should be safe.
Reduces template/copy actions to 2-RTT, loop-20-templates.yml runtime
reduced from 30 seconds to 10 seconds over a 250ms link compared to
v0.2.2, and from 123 seconds compared to vanilla with pipelining
enabled.
PlayContext.delegate_to is the unexpanded template, Ansible doesn't keep
a copy of it around anywhere convenient. We either need to re-expand it
or take the expanded version that was stored on the Task, which is what
is done here.
This needs more work -- pretty certain that python_path and suchlike are
coming from the wrong place. Possibly we need another config_from_..()
specialized for delegate_to.
This change is relatively incomplete -- ideally we could snapshot
os.environ and /etc/environment at startup and respect key deletions
too, but that's a lot more work. Wait for a bug report instead.
Closes#338.
Concurrent calls to ModuleDepService would cause significant wasted
work, as potentially all pool threads run the same uncached module dep
scan.

Ignore timing variance due to problems with the test job.
Given an extracted download of mitogen-2.2.tar.gz, with strategy_plugins
pointing into it, if an old version of the package was pip-installed,
then the old pip-installed package would be imported and override
whatever came from the tarball.
Instead, modify sys.path before attempting any import. This still isn't
perfect, but it's better.
When running any kind of script, rewrite the hashbang like Ansible does,
but subsequently ignore it and explicitly use a fragment of shell from
the ansible_*_interpreter variable to call the interpreter, just like
Ansible does.
This fixes hashbangs containing '/usr/bin/env A=1 bash' on Linux, where
putting that into a hashbang line results in an infinite loop.
* mitogen/ansible_mitogen should only generate ERROR-level logs in
log_path unless -vvv is enabled.
* Targets were accidentally configured to always have DEBUG set, causing
many log messages to be sent on the wire even though they would be
filtered in the master.
Closes#317.
Vanilla Ansible support expandvars-like expansions widely in a variety
of places. Prefer to whitelist those we need, rather than sprinkling
hellish semantics everywhere.
On OS X with case-insensitive filenames, resolving
'ansible.module_utils.facts.base.Hardware' finds
'ansible.module_utils.facts.hardware/__init__.py', because
module_finder's procedure is completely wrong for resolving child
modules. Patch over it for now since it otherwise works for Ansible.
* ansible: use unicode_literals everywhere since it only needs to be
compatible back to 2.6.
* compat/collections.py: delete this entirely and rip out the parts of
functools that require it.
* Introduce serializable Kwargs dict subclass that translates keys to
Unicode on instantiation.
* enable_debug_logging() must set _v/_vv globals.
* cStringIO does not exist in 3.x.
* Treat IOLogger and LogForwarder input as latin-1.
* Avoid ResourceWarnings in first stage by explicitly closing fps.
* Fix preamble_size.py syntax errors.
The failed job result is likely to be "interrupted system call", and we
don't want that to overwrite the SIGALRM handler's "the task timed out",
so just discard it.
