Augustin Cavalier 64d96af568 MIME Sniffer: Use memmem() to speed up matching.
This is now a POSIX method which was widely supported even before
its addition to POSIX, so using it here (including on the build
platform) should be OK.

This takes mimeset -F of the whole src/ hierarchy from around 2.8
seconds to around 2.1 (user time goes from ~1.2s to ~0.6s.) It seems
I/O is a lot of the remainder now.

Also drop the TODO comment; we don't want partial matching like that,
as the sniffing rules would not expect it.

All tests still pass.

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!
