Lighten up fibers by installing "catch" in scheduler

2017-08-06T13:30:49Z

This takes the load off of each fiber and speeds things up.

Rebase fibers on top of schedulers and tasks

2017-08-06T10:59:50Z

This commit refactors fibers to be based on lighter-weight "tasks", and makes the scheduler API more orthogonal. Now there are no more fiber objects (although the fibers layer could re-add them if they are useful), and fibers no longer have names (although again this could be re-added at an upper layer). Also it's the current scheduler that's bound by a parameter, not the current fiber, and as it's a thread-safe parameter it doesn't need to be bound in each fiber.

Garbage collect old condition waiters.

2017-07-31T16:26:54Z

* fibers/stack.scm (stack-filter!): New variable. * fibers/conditions.scm (make-counter, counter-increment!) (counter-reset!, %steps-till-gc): New variables. (, make-condition): Update to take gc-step argument. (wait-operation): Occasionally garbage collect old condition waiters.

Add block-asyncs in fiber->thread resume path

2017-02-20T19:25:12Z

* fibers/operations.scm (perform-operation): Block asyncs in resume callback; otherwise the fiber doing the resuming could be scheduled away.

Fix deprecation warning in (fibers operations)

* fibers/operations.scm: Use (ice-9 threads).

Fix epoll wakeup

2017-02-20T19:09:55Z

* fibers/epoll.scm (epoll): Like a complete idiot, I broke epoll wakeup. Fixed by calling expiry->timeout while epoll-state is waiting.

Update REPL support for run-fibers changes.

2017-02-20T12:24:41Z
