µString 0.1.2 is out today!
µString is a generic microkernel for the Jari OS project. You can checkout it on this website.
This is mostly bugfix release, but it include important improvements:
- Initial namespaces support
- Memory objects now has a full range of memory operation support
- Many other small improvements
Thanks,
Project development is still continuing, however we didn't made the expected progress due the decades.
The main reason is a weak community, while the project was need in active development interest was decreased. In the last year we actually did 20 percent of the planned job. In this case I was need to postpone Stable1 release for one year more, it doesn't mean that Stable1 release will actually done within one year, it's possible to finish it early, the project development isn't linear.
Currently we have a good summary of the tasks, it can be used for new community members (checkout http://factory.jarios.org/devel). As for now we are done with the system architecture and there are many things awaits implementation.
Since the team tested many solutions, I can told that we're going from the prototype development to the real world development.
Thanks,
Jari OS lead.
This year was an year of changes, the project didn't make an expected progress due to the changes in the development team, financial problems and some technical reasons.
However, Jari OS is still alive and development continuing. We slightly moving to the next stage - pure community-style development, however the strategy still the same - short range of features.
Special thanks for those who keep interest to the project.
I hope Jari OS will grow and new community members will join us, anyway thanks to all who made this platform works.
Thanks,
Lead of the Jari OS.
Due to technical difficulties and changes in the development team, Jari OS stable release is postponed for one year.
However, the project continues to evolve despite the current difficulties. The main directions of development at the moment are:
- IDL/ORB
- Refactoring of general subsystems
- Bugfixing
We will provide more documentation and specifications within next 2-3 month, most probably on December of 2010.
Anyway, we're looking for new development team and community members.
Sponsorship of the project was terminated, and at the moment the development of the project occurs independently.
Plans for the first stable release remain unchanged, but the directions of the project will be changed.
One of the first purposes are flexibility and scalability of the operating system, it must be able to create a platform for a variety of groups of developers.
The starting point is the ability to run Jari OS on SBC (such as Vortex86-based boards).
The project will pursue the following objectives:
- Flexibility
- Scalability
- A guaranteed response to system events
- Full support for POSIX
- Documented library and SDK
The project has a few opened tasks, the list is here. There are a list of tasks/subprojects with highest priority:
- i386(x86_32) porting
- help with networking development
- full limits support
In addition, the project will be carried out other research projects in the field of operating systems:
- Namespaces, proxies, translators
- Distributed file system
- Self repairing of fallen services
- The high degree of survivability (non-fatal hardware loss, subsystem fails and so on)
- Capability based security model
- WAN distributed system
Research project has a lowest priority and will appears later.
Thanks.
Project moving to new repository, it will has improved build system, toolchain and other features to make development easy and friendly.
syslibs, core servers, applications and documentation repos will be splitted to one and new hiearchy will be created.
Thanks.
Milestone for a first stable version are fixed and will not be changed before release.
It's a small set of features, but it will makes a system generally usable for some use cases.
There are new milestone below:
- Network sockets/UNIX sockets (with POSIX API) (socketfs will be added)
- UNIX IPC (pipe(), shm_open(), shm_unlink()) (pipefs, shmfs will be added)
- Native Jari OS ELF loader (ld.so) (process service will not load/resolve shared libraries) (POSIX: dlopen() and friends will be added)
- Fully functional file i/o and page cache, RAH support (POSIX functions: fsync(), fdatasync(), msync())
- GNU coreutils port (full)
- Event and system wide bus
- IPC abstraction to make services more portable and flexible (IPC box)
- RPC abstraction (RPC box) to make services ease extensible
- Improvements in microkernel (load-balancing, MAC on kernel objects, bug freeing)
- DAC/MAC on services and userland resources
- Bootstrap process improvements (security, race condition, configuration issues will be fixed)
- Ext2 filesystem fixes (working write support)
- USB limited support (uhci, ehci, ohci(probably) host controllers support, mass storage and raw access support )
- Fixing bugs
- Optimization (including works on bugs appears after -O2 was given to gcc)
- User-friendly SDK for members
- Documentation, manuals and how-to.
And some sugar for a stable version:
- ATAPI CDROM support
- iso9660 support
In addition there are may be some small additions, in this case roadmap page will be updated.
More information on roadmap check out on this page.
One year ago, a small team of developers starts a new development stage. On september of 2008 we has only microkernel prototype, some ideas, and experience taken from the first stage. Those days was a team of three skilled engineers, and this team has a short deadline to design and implement OS prototype. Many things was changed from those days and new people came to team ...
For a one year we has a huge changelog, and many job done.
Our strategy is still the same: short range of features, really working components, short deadlines, no sugar ;)
Now we has a lack of documentation and build tools, but we will change this situation to a better one. Anyway we hope that we will provide a small and fully functional operating system within near 1 or 2 years. And, who knows, may be we will provide remote demonstration access to Jari OS host for everyone.
Thanks to all core team and community members - it was a great job!
Jari OS plans for a beta version has some changes.
First of all is a date: beta release moved to Q4 of 2010 - that means all subsystems features will be frozen and all works will be intended to bug fixing, code clean up and optimization. For near milestones there are will be a series of alpha releases (alpha1 and so on).
Second changes is a feature set, it was also chaned. We are planning to have the following list of features and changes in beta (and it's stable and optimized variant in stable version):
- security layer
- separated ELF loader implemented like library (currently it located in service)
- networking (with sockets)
- improved mappings and file caches
- clear ext2 support (now it's has alpha stage)
- initial usb support (mostly oriented on mass storage support)
- pipes/fifo/POSIX queues/shared memory support
- full and clean ISO C support
- workaround with time zones and time functions
- select/poll functions
- iso9660 (with extensions) support
- ATAPI (cdrom) support
- new RPC protocol (version 2.5) that will be works via DSL
- fully ported GNU coreutils
- system applications
- many other small cases
Also, we will try to add the following:
- XFS port
- SATA support
- Demo distro
- Packages support
- GNU development tools port
For the near time - for the alpha1 release we will show a progress with:
- file mappings and page cache improvements
- external ELF loader
- initial security model
Alpha1 release is planned for september of 2009, other plans will be posted here in october of 2009.
Jari OS version 0.0.1 alpha is out.
All features are implemented, now we have an operating system platform for better development process.
It was a great job. Next releases will be more stable, more featured. We are planning to have a normal networking support, usb stack, ATAPI and other features for stable release (0.0.1).
Currently source tarball and raw hd image is available for download.
