The POSIX specification says that the behavior of specifying O_TRUNC with O_RDONLY is "undefined", but the Linux manpages ominously state "On many systems the file is actually truncated." I tested this, and indeed on Linux the file is actually truncated. This doesn't seem like a very sensible behavior, so in this commit it's changed to return B_NOT_ALLOWED (EPERM) if those flags are specified together. The FAT driver already did this, but most other filesystem drivers just checked write access permissions and truncated the file anyway; so this is indeed a behavioral change.

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!
