Haiku Getting UserlandFS, NetFS

News posted by umccullough on Tue, 2007-02-20 18:12

We are excited to announce that Haiku developer Ingo Weinhold has recently committed UserlandFS to the repository. UserlandFS is designed to provide, for the first time in Haiku (and the BeOS platform), a stable and flexible environment for file system add-on development. Along with UserlandFS, Ingo has also committed several file system modules, including a Reiser FS 3.6 read-only implementation, a RAM FS (which is still work in progress), and NetFS, a Haiku-specific networking file system. NetFS is a native Haiku network file system that provides peer-to-peer networking capabilities for computers running Haiku on a LAN and includes full support for BFS attributes and live queries.

In its current state, UserlandFS is coded to work in BeOS R5, but it will soon be ported to work with the new Haiku file system interface (which is slightly modified implementation from that of BeOS R5). It is hoped that the availability of UserlandFS will accelerate development of more file system add-ons for Haiku.

While a userland debugging "shell" for FS development already exists for Haiku, it has some limitations that can be avoided by using UserlandFS instead. The "FS shell" emulates the relevant part of the kernel (the complete VFS layer) and provides a CLI interface with several testing commands. UserlandFS instead offers the ability to use any application or test program with your FS directly — e.g. the Tracker — and results in the same access patterns you would expect with the file system running in the kernel.

According to Ingo, "the UserlandFS interface is identical to that of the kernel FS interface. Having the kernel interface as an option is particularly nice for developers who want to write a file system for the kernel. They can develop, test and debug in userland, and then just recompile for the kernel. Not only can a buggy FS running in userland not cause KDLs, but the debugging facilities available in userland are also way more comfortable (break/watch points, single stepping, etc.)".

NetFS is currently a working implementation already, and it provides all functionality that could be expected from a file system under Haiku with the use of attribute and live query support. Still missing is a preferences GUI to configure NetFS, so for now server side shares and user permissions are defined using a config file. The client is also capable of automatically locating other servers on the LAN.

Haiku Tech Talk at Google a Success

News posted by koki on Wed, 2007-02-14 09:23
Yesterday was our big day at Google, and we can say with a good degree of confidence that the Haiku Tech Talk was quite successful. We had a very special guest for this event: former Be Inc. CEO Jean Louis Gassée, not only joined us at Google for our presentation, but also gave a few words of support and encouragement for our project. It was great to have JLG's presence, as well as that of the several ex-Be engineers who showed up for the talk. We were also glad to see JAVA for BeOS developer Andrew Bachman join us for this special event. Take a look at the pictures taken during the presentation. A video of the full presentation will be posted on the web later this week; we will post the link here when it becomes available.

SCaLE 5x First Day Report - Part 2

After our first report, Michael's stuff finally arrived and we were able to set up Haiku on a projector screen, which actually helped bring more attention to our booth. The impression that I have been getting from the people visiting our booth is that the reception of our ideal of a desktop OS designed for, focused on, and optimized for the desktop is very positive. It has been a very encouraging experience so far.

We were also extremely pleased to have the presence of Travis Geiselbrecht, the creator of NewOS, who showed up at our booth in the afternoon. Not only did we spend quality time with Travis discussing Haiku and our kernel (which is based on NewOS), but we also had dinner together where we exchanged plenty of stories from the good old days.

We also had our first Birds of a Feather session in the evening, where Michael Phipps introduced Haiku to an audience of approximately twenty people. All the attendants showed great interested in our work, as evidenced by the good number of interesting questions during the Q&A session towards the end of the presentation. In my opinion, the presentation was a success, as it both introduced Haiku to those who did not know about our project, and it also helped show the progress made to those who already knew about it.

Enjoy a few more pictures for your viewing pleasure.

SCaLE 5x First Day Report - Part I

News posted by bga on Sat, 2007-02-10 21:28

SCaLE 5x started this morning and it has been a lot of fun so far. Axel, Michael (Phipps), Jorge (Mare) and myself (BGA) came down to the exhibit floor early this morning to setup the booth in advance of the opening. We have a 10x10 booth with a table and a couple of chairs, so we setup a small form factor desktop PC hooked up to a 20 inch LCD monitor, and a couple of laptops, an IBM running Haiku natively, and a MacBook Pro running Haiku inside Parallels. We are still waiting for an additional PC and a projector that did not make in time, as Michael's luggage was sent to the wrong destination.

There is a lot of traffic on floor, and a lot of people has stopped by and shown interest in what we are doing. And the audience is also right: plenty of geeks with a passion for innovative stuff. Let's hope that we get a good audience at the first BoF tonight.

Stay tuned for another report later today.

Symbolic Milestones

News posted by mmu_man on Sun, 2007-01-28 22:58

Some will argue that these were just meaningless numbers, nevertheless we have reached significant milestones today: 1000th bug entry, and even better, 20000th subversion change. Recent subversion changes include many bug fixes and several additions in the file system area.

Several file system add-ons were ported from BeOS (Haiku has a different VFS interface):

  • NTFS, using a GPLed libntfs, should even handle writing if you don't mind some risk of losing data.
  • NFSv2, from an add-on once published on BeBits, should allow using files from Unix servers and maybe someday be used for network booting along with PXE.
  • GoogleFS, a tech demo showing how queries can be handed over to Google.

In other additions, Marcus Overhagen finished implementing PXE support. PXE is the first step to providing network boot support. The kernel still needs to be programmed to mount the boot volume from the network.

Haiku Website: Taking One Little Step Forward

News posted by koki on Sun, 2007-01-21 22:42

We finally have the long promised new website. It has taken much longer than expected, but hopefully the wait was worth it. I would like to briefly introduce some of the (not so obvious) changes, and try to explain how to make the best of the Haiku website as a tool for the community to contribute to our project.

About Section

  • Haiku Gallery
    For starters, there is now a new Haiku Gallery. The gallery currently has a Haiku Screenshot Tour that gives a good visual overview of what Haiku looks like. We plan to gradually expand the number of screenshots to show various applications running in Haiku, and also use use the gallery to post photos of conferences, presentations and other Haiku related events.
  • Haiku Movies
    There is also a new Haiku Movies page with links to videos on the web showing Haiku. At present, this page lists only a couple of videos, but we would like to expand this list with your help. So, if you know of any Haiku videos on the web that could be added to this list, please drop us a line with the URL, description and author information so that we can add it to the list.
  • FAQs
    The frequently asked questions section has been divided into a General FAQ and a Development FAQ.

Development Section

This section has been slightly changed to make it more compact and focused. We should also note that our Project management and bug/issue tracking system (Trac) is back and that it has a new home at dev.haiku-os.org.

Documents Section

The Documents section has been reorganized into Developer Documents and End User Documents. Each category also has its own subcategories to make it easier to find the kind of document that you are looking for. We will most likely add new document categories as we see fit in the future.

Community Section

  • Haiku Blog-O-Sphere
    We have setup a Haiku Blog-O-Sphere, where the Haiku admins will blog progress reports and other Haiku related posts. This will hopefully give the community a little bit of insight into what the core project members are doing a bit beyond of the commit logs.
  • Community Forums
    The Community Forums have been migrated to the Drupal system. This was a difficult decision (and a bit controversial), but we decided to keep it all under one system, both for consistency of looks and easy of maintenance.
  • Wiki
    Also, as you may have noticed, the wiki has been taken offline. There was too much duplication of content (which we want to avoid), and we would like to repurpose it so that it fulfills a distinct and useful role within the context of our web presence. I hope the community will understand and support this decision.

Other Goodies

At the end of every news post in the front page you will see a few additional icons. As some of you may guess, these allow you to:

  • Bookmark the post on del.icio.us
  • Bookmark the post on Google
  • Digg the post on digg.com
  • Search for the post on Technorati.

This is an easy way to spread the word about Haiku, and help raise its visibility on the web.

If you want an easy way to follow what's going on with Haiku, there are several RSS feeds that you can subscribe to:

As a matter of fact, there are many more pages on the website that have their own syndication feed, which you can easily identify by the icon.

User Accounts

All user accounts were migrated from the old website. If you find that you are unable to login to the new website, please try:

Acknowledgements

The new website was possible thanks to the help of many people. Hopefully, I have not forgotten anyone.

  • Austin Bales, for his valuable ideas.
  • Petter Holt Juliussen, for providing server space at the early stages of development.
  • Gavin James, for his technical help with Drupal.
  • Waldemar Kornewald, for his valuable technical support.
  • Urias McCullough and Curtis Wanner, for helping out with the migration of content.
  • Zumi, for creating nice icons for the site.
  • Stephan Assmus, for creating great looking artwork.
  • All the admins, for providing great insight, and for putting up with my marketing rants for the last several months. :-)
  • The Haiku community at large, for their patience.

To finish, I can't emphasize enough the fact that we are a community based project, and that as such, we rely on the contributions of volunteers that want to see Haiku progress. The website is no exception. This new website is just a little step — hopefully in the right direction. Use it as a tool to inform yourself, to interact with other members of the community, and also to promote Haiku. This is just a start: let's make it even better.

VMWare Graphics Driver for Haiku in the Works

Eric Petit has recently given us the great news on the Haiku mailing list that he has started work on a VMWare graphics driver/accelerant for Haiku. This driver is expected not only to make Haiku snappier when run in VMWare, but it will also enable Haiku's ability to select different screen resolutions and changing them without rebooting the system, a feature that is not available when video is running in VESA mode.

According to Eric's post, his driver is based on Be's driver sample code plus his own code inspired by the X.org VMWare driver. At the moment the driver only implements RECT_BLIT and the cursor functions (the latter is disabled for now since it's a bit buggy).

While the driver is still in early stages of development, it does already work (see screenshot), and Eric is asking those brave Haiku fans out there to test it and provide feedback. For now you can download the sources from this tarball.

The details still need to be worked out, but this driver is certainly to make it into the Haiku tree. Thanks for the great work Eric!

2007 New Year Greeting

News posted by koki on Tue, 2007-01-02 00:10

Another year is gone, and a new one has just began. Looking back, 2006 was a good year for Haiku: we saw not only gains in functionality, features and stability, but also in looks. The USB and the network stacks where two prominent areas where progress was made; lots of other additions and improvements were also made under the hood, and, of course, the expected bug fixes, which were many. Haiku also acquired a more modern look thanks to the gorgeous icon set that was recently put together. Overall, in 2006 we saw many pieces gradually fall into place, making it all come together in very tangible ways.

The Haiku community itself also grew in some new ways. Some devs have made a come back to coding for Haiku; some others have started taking their first steps into Haiku development. 2006 also saw the beginning of a new marketing communications effort, intended to help the project gain more visibility and thus become a better recognized member of the global open source community.

There certainly is still a lot to do to get to the much awaited R1, but we are definitely getting closer by the day. And while we cannot promise when Haiku will be ready for its first official debut, 2007 may at last be the year we have all been waiting for.

It should be noted that none of our achievements would have been possible without the support from our faithful community. To them, our biggest expression of gratitude for their continued support over all these years.

May 2007 bring prosperity, health and peace to everyone.
