Peter Johnson	7c1a7332e1	uv::Async, uv::AsyncFunction: allow calling from within loop	2018-10-16 09:40:59 -07:00
Peter Johnson	172e438cd6	wpiutil: uv::Async: Keep weak reference to loop ... Other handles can only be used within the loop itself, but Async is intended to be used from another thread. This introduces the possibility of a race condition between the loop being destroyed and the Async being destroyed. Change Async to keep a weak reference to a loop and check it before performing libuv operations.	2018-10-16 09:40:59 -07:00
Peter Johnson	1a7a0db1ff	wpiutil: Change uv::AsyncFunction to use promise/future. ... This allows the called function to pass along the promise to another asynchronous callback. To avoid memory allocations, add a home-rolled, simplified, non-allocating version of std::promise and std::future as wpi::promise and wpi::future.	2018-10-16 09:40:59 -07:00
Peter Johnson	57490e0002	Add uv::AsyncFunction to do a roundtrip function call to a uv::Async ... This optionally blocks to wait for a return value.	2018-08-20 22:21:53 -07:00
