David Wilson	3fab8a3af5	ansible: connection delegation v1 ... This implements the first edition of Connection Delegation, where delegating connection establishment is initially single-threaded. ansible_mitogen/strategy.py: ansible_mitogen/plugins/connection/*: Begin splitting connection.Connection into subclasses, exposing them directly as "mitogen_ssh", "mitogen_local", etc. connection types. This is far from removing strategy.py, but it's a tiny start. ansible_mitogen/connection.py: * config_from_play_context() and config_from_host_vars() build up a huge dictionary containing either more or less PlayContext contents, or our best attempt at reconstructing a host's connection config from its hostvars, where that config is not the current WorkerProcess target. They both produce the same format with the same keys, allowing remaining code to have a single input format. These dicts contain fields named after how Ansible refers to them, e.g. "sudo_exe". * _config_from_via() parses a basic connection specification like "username@inventory_name" into one of the aforementioned dicts. * _stack_from_config() produces a list of dicts describing the order in which (Mitogen) connections should be established, such that each element is proxied via= the previous element. The dicts produced by this function use Mitogen keyword arguments, the former di. These dicts contain fields named after how Mitogen refers to them, e.g. "sudo_path". * Pass the stack to ContextService, which is responsible for actual setup of the full chain. ansible_mitogen/services.py: Teach get() to walk the supplied stack, establishing each connection in turn, creating refounts for it before continuing. TODO: refcounting is broken in a variety of cases.	8 years ago
