||
| #### Lifetime EventLoop | ||
|
|
||
| https://crystal-lang.org/2024/11/05/lifetime-event-loop/ | ||
|
|
||
| Refactor Lifetime Event Loop ([#14996], [#15205], [#15206], [#15215]) | ||
|
|
||
| In the process we also refactored the `Crystal::EventLoop` namespace ([#15226]), | ||
| and some details of the `libevent` ([#15243]) and IOCP event loop drivers ([#15238]). | ||
|
|
||
| This effort is part of the ongoing [project to improve multi-threading support](/2024/02/09/84codes-manas-mt) | ||
| with the help of [84codes]. | ||
| Next we'll incorporate execution contexts from [`ysbaddaden/execution_context`](https://github.com/ysbaddaden/execution_context) | ||
| into the standard library, implementing [RFC 2](https://github.com/crystal-lang/rfcs/pull/2). | ||
|
|
||
| *Thanks [@ysbaddaden]* | ||
|
|
||
| #### Stabilized platform support | ||
|
|
||
| In the process of testing the event loop implementations we updated specs and | ||
| fixed some smaller issues with platform support on operating systems without | ||
| automated continuous testing (OpenBSD, FreeBSD, Dragonfly BSD and NetBSD). | ||
|
|
||
| *Thanks [@ysbaddaden]* | ||
|
|
||
| #### `Process::Status` | ||
|
|
||
| - *(system)* Add `Process::Status#exit_code?` ([#15247], thanks @straight-shoota) | ||
| - *(system)* Add `Process::Status#abnormal_exit?` ([#15266], thanks @straight-shoota) | ||
| - *(system)* Fix `Process::Status` for unknown signals ([#15280], thanks @straight-shoota) | ||
| - *(system)* Raise on abnormal exit in `Procss::Status#exit_code` ([#15241], thanks @straight-shoota) | ||
| - *(system)* Redefine `Process::Status#normal_exit?` on Windows ([#15255], [#15267], thanks @straight-shoota) | ||
| - *(system)* Adjust definition of `ExitReason::Aborted` ([#15256], thanks @straight-shoota) | ||
|
|
||
| *Thanks [@straight-shoota]* | ||
|
|
||
