Jérôme Duval 3db1859b48 kernel/fifo: honor O_NONBLOCK on open() for FIFOs
according to POSIX:
- O_NONBLOCK set:
	* read-only open() shall return asap
	* write-only open() shall return an error if no reader.
- O_NONBLOCK clear:
	* read-only open() shall block until a writer opens.
	* write-only open() shall block until a reader opens.

for FIFOs used for pipes, open with O_NONBLOCK then reset O_NONBLOCK.

can be tested with:
bash -norc -c '/bin/printf "test" > >(/bin/tee -a trace.log) 2>&1'

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
