* The first problem was the O(n^2) complexity of the algorithm, it's now linear and try to act in a circular way by dispatching events and reading the port in a balanced way. This exclude a certain degree of possible deadlocks. * Add detection and escape when the system try to kill the thread. This solve some blocking issues on exit et similia that i had with libjackcompat. * The algorithm choose soon which event to focus on. * Lateness is calculated just before the event is dispatched as it is the more appropriate place, otherwise we would be calculating something imprecise/guessed. * Remove timed_event_queue::queued_time. It's more precise to just use the RealTime() before to Dispatch the event. * It should solve the BSoundPlayer lateness problems. * With those improvements the media_kit is not going to lock completely under stress conditions, instead it try to work in a best effort shape. * There's still room for improvements, for example i'm considering some strategies in lateness situations such as update scheduling latency, try to decrease waiting time and detect when we are too early on the other hand to recover when the load go down. * Thanks to Julian Harnath for sharing his WIP patch which helped with some controls such as avoiding negative lateness. * Comments are welcome! |

Haiku
Homepage | Mailing Lists | IRC Channels | Issue Tracker | API docs
Haiku is an open-source operating system that specifically targets personal computing. Inspired by the BeOS, Haiku is fast, simple to use, easy to learn and yet very powerful.
Goals
- Sensible defaults with minimal configuration required.
- Clean, clear, concise code.
- Unified desktop environment.
Trying Haiku
Haiku provides pre-built nightly images and release images. Haiku is compatible with a large variety of hardware, but in case you don't want to "take the plunge" and install Haiku on bare metal, you can install it on a virtual machine (VM) instead. If you've never used a VM before, you can follow one of the "Emulating Haiku" guides.
Compiling Haiku
See ReadMe.Compiling.
Contributing
Haiku is a meritocratic open source project with a large variety of tasks. Even if you can't write code, you can still help! Haiku needs designers, (technical) writers, translators, testers... Get involved and help out!
Contributing code

Contributing documentation
The main piece of documentation that still needs work are the API docs (found
in the tree at docs/user). Just find an undocumented class, write
documentation for it, and submit a patch.
