Brendan Burns db08b61616 Added instructions for adding a new backend. 2014-05-20 16:00:48 -07:00
Solomon Hykes 74eaf8492f Merge pull request #9 from shykes/pr_out_beam_messages_can_attach_arbitrary_file_descriptors 2014-05-19 14:23:16 -07:00
Solomon Hykes c9a7897773 Beam messages can attach arbitrary file descriptors. 
Each transport is responsible for implementing file passing using the
best available method.

Current state of implementation:

* inmem: full
* unix: not yet implemented
 2014-05-19 14:21:45 -07:00
Solomon Hykes 6fedd8c7ab Construct messages with explicit fields to allow for new fields 
This is in preparation for the new `Attachment` field.

Solomon Hykes c6f0a70141 Move utilities and interfaces out of `inmem` 
* `utils.Buffer`: a Sender which stores messages in a slice
* `utils.Copy`: beam equivalent of `io.Copy`
* `utlis.NopSender`: a Sender which silently discards messages
* `utlis.NopReceiver`: a Receiver which always returns EOF

Solomon Hykes b9c316df29 inmem: complete Copy implementation 
Copy can now handle arbitrary nesting of streams, without knowing the
underlying type of either the source or destination.

It does this by attempting `SendTo` and `ReceiveFrom`, then if that is
not supported, falling back to nested copies in separate goroutines.

Solomon Hykes 12b5459a1c inmem.StackSender: a dynamic beam forwarded with health checks 
StackSender forwards beam messages to a dynamic list of backend receivers.
New backends are stacked on top. When a message is sent, each backend is
tried until one succeeds. Any failing backends encountered along the way
are removed from the queue.

Solomon Hykes 2c9e18009f Fix stdin handling in engine.Sender and engine.Receiver 
This introduces a superficial change to the Beam API:

* `beam.SendPipe` is renamed to the more accurate `beam.SendRPipe`
* `beam.SendWPipe` is introduced as a mirror to `SendRPipe`

There is no other change in the beam API.
