Ideas

The Haiku Project has been selected to participate in Google Summer of Code™ 2011!

Qualifying students can apply for a Haiku project (see the list of suggested projects below)
between March 28th and April 8th, 2011. For details about how to apply, please check out
Students: How to Apply for a Haiku Idea.

According to other mentor organizations, the most successful
Google Summer of Code projects are the ones proposed by the students
themselves. The following list represents our ideas and wishes
of our project. However, suggesting your own idea is encouraged!

If you find an idea marked as "big" interesting but feel you cannot completed in time,
feel free to suggest splitting it into smaller parts in your proposal.
Also, many of these ideas are not sufficient as stand-alone projects and
would need to be combined with others on this list or of your own suggestion.

Students, who intend to submit applications on ideas
that are part of other accepted mentoring organizations,
need to contact both Haiku and the other mentoring organization.

Project Areas

Applications

Updating AbiWord

Even though an older AbiWord port is being hosted at
OSDrawer : AbiWord Project Page,
the AbiWord project would prefer the port to use their current sources.

The student is responsible for determining which aspects of this project to persue.

VirtualBox port to Haiku

A port of VirtualBox to Haiku, would allow developers and users to run another operating system within Haiku. Preliminary VirtualBox port to Haiku

  • Skill set: userland development, kernel development, possibly x86 assembly

Enhancements for Virtualization Software

Haiku works nicely both on real hardware and virtualized machines, but lacks most of the so-called "guest additions" that allows smoother integration with the host. This include changing resolution on window resize, mouse automatically switching from host to guest and back, file sharing. Write such a guest addition package for virtualbox or/and vmware

  • Skill set: userland development, driver development

Kernel

Filesystems: general improvements (BIG)

Haiku has great support for its own filesystem, but most others are only available read-only, or not at all. It is way better for interoperability with other systems to be able to read and write to these disks.

  1. ReiserFS, BTRFS, exFAT: write support
  2. UFS2, ZFS: Read (& Write) support
  3. SMB, Windows shares: Read (& Write) support
  4. HAMMER FS: Read (& Write) support
  • Skill set: kernel, and driver development

IMAP FS: File system access to an IMAP account

In Haiku emails are stored as individual file with extended attributes. Mounting an IMAP account as a local file system is therefore a natural fit. The file system should have full read and write support (deleting mails (files), creating folders, and moving mails between folders, etc.) with local caching for better performance.

  • Skill set: kernel and file system (driver) development, network development

NFSv4 client with xattr support and caching

Haiku has an NFS client, but using the out of date NFSv2 specification and the old file system API. This makes it unusable for any practical purpose. Also, the current implementation doesn't support caching, which makes it slow, and lacks xattr handling, which is very important in Haiku.

  • Skill set: network protocols, maybe kernel development, userland development

BFS Partition Resizer

An often requested feature. This includes being able to resize the filesystem and it's descriptive structures (eg, think of resizing an image file) and being able to resize the partitions on the drive. Ideally integrated within DriveSetup.

  • Skill set: Driver development

Drivers

USB 3.0 support

XHCI implementation Haiku has already some support for UHCI, OHCI and EHCI.

  • Requirements: acquiring a PCI-e USB 3.0 board (30$).
  • Skill set: kernel, and driver development

USB Video (UVC)

This driver will support higher end webcams and other devices. This should be designed with portability to other OSes, which encourages the re-use of coding efforts for both Haiku and non-Haiku operating systems.

  • Requirements: owning an UVC webcam.
  • Related code: skeleton driver
  • Skill set: kernel, and driver development

ACPI Video Extensions

ACPI Video Extensions, as specified in ACPI Spec 4.0a Appendix B, adds special support to handle multiple output devices such as panels and TV-out capabilities, brightness control as well as special power management features.

Suggested work: Detect attached devices for display adapters, implement a basic driver for a display, allow display switching and brightness control.

  • Requirements: computer with ACPI that has Acpi Video Extentions (_DOS _DOD and so on)
  • Skill set: kernel development, general C/C++, userland development

AV/1394 support

Our Firewire stack supports DV receiving, but not controlling the A/V device (ie play/stop). This requires to modify the Firewire stack for FCP frame support. See AV/C Digital Interface Command Set General Specification for reference.

  • Requirements: a DV camera, a machine with a Firewire port.
  • Skill set: kernel development, API design, general C/C++, userland development

TTY Layer

The TTY layer is needed for proper serial port support in Haiku. Until now the serial port was reserved for kernel debugging, but it is now time for proper userland support. Rewrite the API that was available in BeOS R5, and make sure it can be used with a real serial port. USB to serial converter may or may not be included.

Currently, the TTY layer is written mostly with the usb_serial in mind, so it uses stuff that might not be easy or possible at all to use in more low-level drivers (like pc_serial). The API could use improvements. Locking issues exist. Also the generic module is not yet in the image due to these.

Note: This task could include finishing phoudoin's libusb port, which would help to make the driver more feature complete.

  • Skill set: kernel, and driver development
  • Tickets: #35 #3232

Network

Bluetooth Stack Improvements

Haiku Bluetooth Stack implements basic functionality on lower and middle layers, this functionality needs to be completed and Bluetooth 2.X possibilities explored.

  • Requirements: Bluetooth enabled Haiku system
  • Skill set: C++, kernel development, userland development, global bluetooth stack knowledge(optional)
  • Tasks: RemoteDevices Database, UserLand tools(Preferences), Pairing/Auth/Encryption use cases, etc.

Integrate our PPP implementation

Port the PPP implementation to our new network stack. Add phone-line modem support, including HDLC framing and VJC compression (porting both algorithms is sufficient, but make sure the license is compatible to MIT). Implement CHAP authentication. Find and fix bugs.

  • Tickets: #812, #869, #873, #922, #923, #1059, maybe: #1057, #1058
  • Skill set: multi-threading basics, maybe network protocols and some kernel/drivers development, maybe UI development

User Interface

Preflet GUI refactoring

Several preference applications (aka preflets) could be redesigned. This includes (but not limited
