Revision 1.104 - (hide annotations)
Sun Aug 3 18:23:10 2008 UTC (5 years, 8 months ago) by heller
Branch: MAIN
Changes since 1.103: +11 -5 lines
Add some flow-control.

* swank.lisp (make-output-function): Synchronize with Emacs on
every 100th chunk of output.
(wait-for-event,wait-for-event/event-loop,event-match-p): New
functions.  Used to selectively wait for some events and to queue
the other events.
(dispatch-event, read-from-socket-io): Tag non-queueable events
with :call.
(read-from-control-thread, read-from-emacs): Process
:call events only; enqueue the others.

(*log-output*): Don't use synonym-streams here.  Dereference the
symbol until we get at the real stream.
(log-event): Escape non-ascii characters more carefully.

* swank-backend.lisp (receive-if): New function.
Update backends accordingly. (not yet for ABCL and SCL)

* slime.el (slime-dispatch-event): Handle ping event.
