The pre-allocate functionality was added to Haiku in hrev54704. It needs support at the file system level though, and it is yet to be implemented by BFS. Some applications (and glibc!) implement a fallback mechanism using ftruncate(), including the LLVM tools, but they go to this fallback mechanism when it is clear that the operation is not supported. In particular they look for EOPNOTSUPP. The current implementation returns B_UNSUPPORTED from the vfs layer when a file system does not implement the feature. This error code this not map to a POSIX error. This change converts it to EOPNOTSUPP.

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!
