Add asyncSpawn() procedure and tests. (#123) 
Deprecated asyncDiscard() procedure.
Bump version to 2.5.2.
 2020-09-01 21:41:18 +03:00
Zahary Karadjov e6d50b7736 Revert "some metrics for monitoring futures (#85)" 
This reverts commit e45ef32b5b.

Metrics implemented this way, with a lock inside the otherwise tight
event loop are not consistent with the chronos architecture that for
good or bad uses thread local variables to avoid them - the solution
does not have rough consensus behind it, and other avenues should be
explored for this generally useful functionality.

Zahary Karadjov 826d48c4aa Revert "more docs (#111)" 
This reverts commit d0a17d551f.

Moving CancelledError outside of the established Nim hierarchy is
not a solution that has rough consensus and has an unknown impact
on compatibility with otherwise correctly implemented cancellation
code (for example when `CatchableError` is caught, cleanup is done,
then the exception is reraised). Further, this breaks the established
convention in the Nim community that Exception should not be inherited
from, complicating compatibility with future Nim versions that may
enforce this more strongly.

Zahary Karadjov 03f4a26829 Revert "yieldAsync() (#120)" 
This reverts commit 284d677815.

There is no rough consensus for how this should be implemented and
whether it's needed indeed - a use case that cannot be solved with
a queue or a lock/event should be identified before pursuing this
functionality.

Zahary Karadjov 34b81961d3 Revert "asyncCheck(): don't raise exception on cancellation (#121)" 
This reverts commit baf33f04ea.

This change hides exceptions that should be handled explicitly -
asyncCheck is a debugging tool that should only be used in
exception-free situations (indeed, to fail when the operation
unexpectedly raises). There is no rough consensus behind this
change.
