Augustin Cavalier 7959ac39f1 kernel/condition_variable: Unblock after unset, if possible. The previous round of this code unblocked after unset universally, but that was incorrect in the case where the thread was not in the "waiting" state before we unset. Yesterday I changed that to just unblock before unset universally. It seems, however, that thread_unblock is so time-consuming that the other thread will wake up and begin doing things before unblock returns for us, and then it will hit the timeout before we have a chance to unset. So, now we unblock later if it is possible to do so. It seems very strange, though, that thread_unblock will not return in a small but significant number of cases before the unblocked thread actually starts running (note that we are in interrupts-disabled mode here, so that is not the problem.) That sounds like a problem for another day. Should fix #17455, possibly in tandem with the previous commit.		2021-12-08 17:39:02 -05:00

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!
