* 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.
This is like FileService but blocks until the file is pushed by a parent
context, with deduplicating behaviour at each level in the hierarchy. It
does not stream large files, so it is only suitable for small files like
Python modules.
Additionally add SerializedInvoker for use with PushFileService, which
ensures all method calls to a single service occur in sequence.
To support detach, we must be able to preload the target with every
module it will need prior to detachment. This implements the
intermediary part of the process (i.e. the Ansible fork parent) --
receiving LOAD_MODULE/FORWARD_MODULE pairs and ensuring they reach the
child.
Ideally it would be possible to specify a callback function, but this is
not possible for proxied connections. So simply provide the 3 most
useful modes, defaulting to the most secure.
Closes#127. Closes#134.
machinectl does not support any sensible form of pipe to the child
process, so it is necessary to bypass it when talking to a systemd
container (see systemd/systemd#8850).
This can also form the basis for issue #223, where the post-fork
namespace switching dance required to connect to the Pythonless
container will be the same.
