Tony Garnock-Jones 53e26b08a1 Many improvements to the netstack TCP implementation.
- New timestate `on-timeout` complementing `stop-when-timeout`
 - IP layer avoids spurious reordering
 - Demo HTTP server sends 4kB responses, for testing

 - TCP now has something closer to proper sliding-window behavior
 - TCP RTT estimator
 - TCP now uses timestate driver rather than raw timer driver
 - Many small TCP bugs found and fixed

Tony Garnock-Jones 6c4ae38499 Make HLL `dataspace` no longer automatically `quit-dataspace`. Fixes #20. 2017-09-25 23:52:29 +01:00
Tony Garnock-Jones 4a4f43b2cb Use initial assertions to convey initial TCP packet to new state vector.
This reduces latency of accepted connections significantly: no longer
do we wait for a SYN timeout-and-retransmit at the other end.

Tony Garnock-Jones 68ba2f74a6 Split dataspaces in to relay and mux sublayers.
This is a major change to the previous design, and also a change with
respect to the semantics in the ESOP 2016 paper. All the complexity of
echo-cancellation is stripped out of the core dataspace semantics, and
the relaying protocol is changed from one constructor, `at-meta`, to
two, `inbound` and `outbound`. The relay connecting a dataspace to its
container is now completely symmetric with the contained actors: it
initially asserts interest in what it is to relay, just like any other
actor would. Dataspaces no longer treat relaying specially.

This commit has updated all (I think) of the non-graphical examples. The
graphical code remains to be done in a following commit.

Tony Garnock-Jones 75ef296c58 Repair TCP state-vector tracking.
I had missed that the syndicate/monolithic implementation
was *subscribing* with a #t filter, but *projecting* without one.

Tony Garnock-Jones 015d7c38dd Properly evaluate some TCP stop-when conditions.
Prior to this commit, the stop-whens were using
current-inexact-milliseconds in a comparison to detect a timeout,
meaning that timeouts would be missed. This commit introduces a
redundant copy of current-inexact-milliseconds in a field and changes it
on every event so that stop-when expressions involving the field are
reevaluated properly frequently.
