General release notes

  • Fixed the bootup sequence to actually load cluido properly, from the ramdisk using the boot, virtual_file_system,fat and initial_ramdisk servers together. This item itself is worthy of its own story; I have blogged about it at great length here: http://perlun.eu.org/en/2017/12/30/chaos-why-is-the-boot-server-unable-to-read-the-startup-script
  • Changed bootloader from grub-legacy to GRUB 2, the current version of GNU GRUB. This helped in supporting the next bulletpoint, namely:
  • Make it possible to boot from a USB pen device. Just use cp (on Linux) or Rufus (on Windows) to write the .iso to the proper device and you should be able to boot it. Please, give it a try and share any feedback about this here in our GitHub repo!
  • Added CI building of Docker images on each push to master. Our image can be found here, and you should be able to run it by simply executing docker run -it chaosdev/chaos.

General release notes

  • Started using Semantic Versioning for our version numbers. New releases will hereafter be 0.2.0, 0.3.0 until we eventually reach 1.0.0.
  • Many small improvements. The biggest single improvements are:
    • First steps toward a Raspberry Pi port.
    • The code is now compilable with gcc 6 and 7. Caveat: The resulting binaries have not been tested. Use at your own risk!
    • Use stdint.h instead of declaring our own u32, i32 etc. types.
  • The full details can as usual be found below.

General release notes

No major changes or improvements; mostly a "small improvements" release. The single biggest improvements are:

  • Updated the Vagrant & Travis settings to use gcc version 5 (instead of version 4.7 which was the previously assumed version).
  • Added support for building servers in Rust. Rust is still a quite "new" language in terms of stabilization and feature support; the first "stable" version 1.0 was released in May 2015. Still, it has interesting features and is a much more "modern" systems programming language than C/C++ which means it should be quite useful for writing parts of chaos with it. Don't expect a full system rewrite in Rust within any near future though... 😉

Details

  • #55: Vagrantfile: Added gdb package and .gdbinit config
  • #56: Added very basic support for Rust compilation
  • #58: Added Rust libcore and rlibc
  • #60: Simplified grub stage2 copying as a result of #52
  • #61: rakelib/common_rules.rake: Minor lint fixes.
  • #62: Updated to gcc version 5.
  • #63: Use rust nightly from last night.
  • #64: Re-enabled code that downloads and unpacks rlibc.
  • #65: Recompiled the libcore and rlibc.
  • #66: Linter fixes, to be Rubocop clean.
  • #67: Removed autochaos

General release notes

This version brings in some of the stuff that was missing in the previous release (most notably, the ipv4 and pci servers). Apart from that, there is really no "new" stuff. Let's see what 0.0.4 has in store...

Details

  • #44: Fixed network servers (ipv4 and loopback)
  • #46: cluido: Adjusted version and fixed license
  • #47: cluido: Wait for ipv4 to become available
  • #48: cluido: Wait for vfs to be available
  • #49: cluido: Fixed the top command to display the correct process name
  • #50: cluido: Made top display times in percentage
  • #51: Removed old GPL-licensed network drivers
  • #52: Vagrantfile: Changed to 32 bit Debian box
  • #53: Made the pci server work again
  • #54: Fixed cpu_reset to not cause a warning in VirtualBox

General release notes

  • First release of chaos in more than 10 years. 🎉
  • Brings much of the existing code base into shape, making it work with recent versions of e.g. gcc. Custom build tool (autochaos) has been mostly superseded with a set of Rake-based files instead (#3).
  • Floppy image has been superseded with an .iso image, which should give us loads more space for servers and programs. As a consequence of this, the release is distributed both as source code and an easily usable .iso file which can be used with any VM software (VirtualBox, Parallels, VMware, etc.). In other words: you do not need to compile chaos yourself to be able to test it, which is kind of cool.
  • Some servers (like the pci and ipv4 servers) are still not updated to the new Rake-based build. They are not included in compiled form in this release. We hope to provide an updated 0.0.3 release within the reasonably near future, where more servers are included.

Details

  • #10: System hangs in process.c
  • #11: Illegal page fault when starting the vga server
  • #12: Kernel tried to lock a mutex in a situation where tss_tree_mutex was already locked
  • #13: Enabled Travis CI builds

  • #20: Updated .gitignore list
  • #21: [KERNEL BUG] update_data: tss_list == NULL (dispatch.c:94, process = console (1), thread = unnamed (3)
  • #22: Removed g++ remnants
  • #24: Added unit test infrastructure
  • #25: Some kernel variables have the wrong values on startup
  • #26: Misc cleanups and closed #25
  • #27: Rewrite system_calls.pl in Ruby
  • #30: Changed thread_create() to take the new thread entry point as parameter
  • #31: Make chaos bootable again (umbrella issue)
  • #33: Made the boot server work again
  • #34: Made the VFS server work again
  • #36: Create ISO image on build

  • #38: Made the FAT server work again
  • #39: Added .gitattributes to force LF line endings
  • #41: Made cluido work again
  • #42: Make some of the remaining libraries compile again
  • 4a5deca: Fixed bug that caused the wrong process name to be printed in debug_crash_screen().

(and probably a bunch of other smaller improvements as well)
