cl-async with-event-loop doesnt exit (hangs) when there is a future error inside it.

[nightshade427]

Why does this hang when using branch using "pre libuv merge" release (cant switch over till the bugs in libuv cl-async and carrier are fixed up, see https://github.com/orthecreedence/carrier/issues/5)

It hangs and doesnt exit, even though carrier triggered (signal-error) and with-event-loop should catch it and exit (it used to)

It hangs with this as well:

(as:with-event-loop ()                                                                                                                                                   
            (asf:alet ((mine (drakma-async:http-request "http://nick.devs.firma8.com:8889/")))                                                                                    
              (format t "~%mine: ~s~&" mine)))

But, this works as expected and exits the event-loop, with the same branches/releases used but using drakma instead (getting same error, the event loops returns).

            (asf:alet ((mine (drakma:http-request "http://nick.devs.firma8.com:8889/")))                                                                          
              (format t "~%mine: ~s~&" mine)))

It looks like it does this with the latest cl-async (using libuv) as well.

It used to return from event loop when there was an error signaled, now it just hangs. :(

[orthecreedence]

Hey, can you try again? We made a number of changes and improvements to the error handling system in cl-async. I'm wondering if this clears things up for you.

[nightshade427]

Nope still does it. I think I'm going to switch over completly to blackbird instead of continuing to use cl-async-future. Will let you know how it goes.

[orthecreedence]

Hey any word on this?

[nightshade427]

I just tried to repo and can't. I think it's good.
