Proposed fix: change
('dead (error "epoll instance is dead"))))
to
;; This can happen if a fiber was waiting on a condition and run-fibers completes before
;; the fiber completes and afterwards the condition is signalled. In that case, we don't
;; have to resurrect the fiber or something, we can just do nothing.
;; (Bug report: https://github.com/wingo/fibers/issues/61)
('dead #t)))
and add the test to the test suite?
(Edit: clarification: I did not test this.)
from fibers.
Minimal test case:
(use-modules (fibers) (fibers conditions) (fibers scheduler))
(define c (make-condition))
(run-fibers
(lambda ()
(spawn-fiber (lambda () (wait c)))
(yield-current-task)) ; let the other fiber wait forever
#:hz 0 #:parallelism 1) ; it fails both with and without, preemption is another complication, so keep things simple for now by not preempting
(signal-condition! c)
from fibers.
Description:
When a fiber is waiting on a condition and run-fibers completes before the fiber completes and afterwards the condition is signalled, ‘epoll instance is dead’ results.
