David Wilson b595314619 docs: fix intensely annoying _prefix, 2 years later. 7 years ago
David Wilson 6aeb4e9f05 issue #164: precisely emulate Ansible's stdio behaviour.
* Use identical logic to select when stdout/stderr are merged, so
  'stdout', 'stdout_lines', 'stderr', 'stderr_lines' contain the same
  output before/after the extension.

* When stdout/stderr are merged, synthesize carriage returns just like
  the TTY layer.

* Mimic the SSH connection multiplexing message on stderr. Not really
  for user code, but so compare_output_test.sh needs fewer fixups.

David Wilson e0381606af Ensure remote_tmp is respected everywhere.
Logic is still somewhat different from Ansible: we don't have to care
about sudo/non-sudo cases, etc.

David Wilson 6670cba41c Introduce handler policy functions; closes #138.
Now you can specify a function to add_handler() that authenticates the
message header, with has_parent_authority() and is_immediate_child()
built in.

David Wilson 8676c40674 core: make _start_transmit / _stop_transmit async-only
For now at least, these APIs are always used in an asynchronous context,
so stop using the defer mechanism.

David Wilson 48351a1889 issue #155: parent: support Context.shutdown(), reap children on exit.
This permits graceful shutdown of individual contexts, without tearing
down everything.

Update mitogen.parent.Stream to also wait for the child to exit, to
prevent the buildup of zombie processes. This introduces a blocking wait
for process exit on the Broker thread, let's see if we can get away with
it. Chances are reasonable that it'll cause needless hangs on heavily
loaded machines.

David Wilson 6a74edce6b issue #155: parent: move master.Context into parent.
The Context and Router APIs for constructing children and making
function calls should be available in every parent context, as user code
wants to have access to the same API.

David Wilson 54ff1c90fa issue #155: add DEL_ROUTE, propagate ADD_ROUTE upwards
* IDs are allocated by the parent responsible for contructing a new
  child, using ALLOCATE_ID to the master as necessary to allocate new ID
  ranges.

* ADD_ROUTE is sent up the tree rather than down. This permits
  construction of the new context to complete concurrent to parent
  contexts learning about its existence. Since all streams are strictly
  ordered, it's not possible for any parent to observe messages from the
  new context prior to arrival of an ADD_ROUTE from the parent notifying
  of its existence.

  If the new context, for example, implements an Ansible async task, its
  parent can start executing that without waiting for any synchronous
  confirmation from any parent or the master.

* Since routes propagate up, it's no longer possible for a plain
  non-parent child to ever receive ADD_ROUTE, so that code can be moved
  out of core.py and into parent.py (-0.2kb compressed).

* Add a .routes attribute to parent.Stream, and respond to disconnection
  signal on the stream by propagating DEL_ROUTE for any ADD_ROUTE ever
  received from that stream.

* Centralize route management in a new parent.RouteMonitor class

David Wilson 20f5d89dfa issue #156: fix several more races
* Don't need to sleep if queue>sleepers, can just pop the right queue
  element and return it.

* If queue>sleeping and waking==sleeping, no mechanism existed to ensure
  a thread newly added to sleeping would ever be woken. Above change
  fixes that.

* Cannot trust select() return value, scheduler might sleep us
  indefinitely while put() writes a byte.

* Sleeping threads didn't pop FIFO, they popped in whatever order
  scheduler woke them up. Must recover index and use it to pick the pop
  index.
