060d8b185e Introduce AsioDualEvent 2025-05-14 12:24:28 +02:00
Alexander A. Klimov
331ba1f661 Rename AsioConditionVariable to AsioEvent 
The current implementation is rather similar to Python's threading.Event, than to a CV.

SpawnCoroutine: move callback into wrapper lambda 
f isn't used otherwise in the function, so if possible, it can just be moved into the lambda, avoiding a copy.

d1d399f8b3 Avoid multiple #if in a single function call expression 
Simply giving two entire call expressions for either Boost version greatly
improves readability in my opinion.

fb2b2e2d5b Don't use removed boost::asio::spawn() overload if Boost >= v1.87 2025-04-14 17:30:19 +02:00

0662f2b719 In a coroutine, re-throw everything ex. std::exception (and inheritors) 
not just boost::coroutines::detail::forced_unwind.

This is needed because as of Boost 1.87, boost::asio::spawn() uses Fiber, not Coroutine v1.
https://github.com/boostorg/asio/commit/df973a85ed69f021

This is safe because every actual exception shall inherit from std::exception. Except forced_unwind and its Fiber equivalent, so that `catch(const std::exception&)` doesn't catch them and only them.

92ab913226 Timeout#Timeout(): don't pass yield_context to callback 
It's not used. Also, the callback shall run completely at once. This ensures that it won't (continue to) run once another coroutine on the strand calls Timeout#Cancel().

c7293de91d IoEngine: Always log coroutine exception diagnostics 
While analyzing a possible memory leak, we encountered several coroutine
exception messages, which unfortunately do not provide any information
about what exactly went wrong, as exception diagnostics were previously
only logged at the notice level.

2c0e0da2d9 Introduce IoEngine::SpawnCoroutine wrapping asio::spawn and Boost exceptions 
This is required to

- catch all exceptions and wrap them into Boost exceptions. They
are the only ones allowed with Boost.Coroutine.
- set a dedicated coroutine stack size for Windows.
