mksh-current version "R48 2013/11/17" (only this version, no others) suffer from a now-known regression which can make your MirBSD system unbootable. Please immediately either revert to an earlier version (such as a stable release) or update to "R48 2013/11/29" from AnonCVS.

This reverts the fix for “x="X 1 2"; showargs ${x#X}”, which nevertheless is a genuine bug. Contributions fixing it without introducing any such regressions welcome…

Rolling is the new buzzword

Tags: snapshot

The MirOS Project is proud to announce that the NetInstall area contains a fresh snapshot of MirBSD-current for the i386 and sparc architectures. In due time, a hand-crafted Live ISO image, with some packages configured and grml-mir added, will be published here, so watch this space ;-)

As someone in IRC already mentioned, MirBSD is currently published on a “rolling release” schedule (although we’ll eventually release MirBSD #11… some day). The snapshots are intended mainly for people to use when installing, or trying out MirBSD, but also as an upgrade aid (so recompiling afterwards (to be even more up to date) is very easy) and a baseline for binary packages (although there have been few (though MuPDF is a recent noteworthy addition) MirPorts packages lately, and I somehow doubt bsiegert@ wants me to gift one of my SPARCstation boxen to him for building pkgsrc® quarterlies).

mksh/Win32

18.07.2013 by tg@

Michael Langguth and Scalaris AG asked me to publish the mksh/Win32 Beta 14 source and binary archive, and it is with joy I’m doing this.

Checksums and Hashes

  • RMD160 (ports/mksh-w32-beta14.zip) = 0dc8ef6e95592bd132f701ca77c4e0a3afe46f24
  • TIGER (ports/mksh-w32-beta14.zip) = 966e548f9e9c1d5b137ae3ec48e60db4a57c9a0ed15720fb
  • 1181543005 517402 /MirOS/dist/mir/mksh/ports/mksh-w32-beta14.zip
  • MD5 (ports/mksh-w32-beta14.zip) = b57367b0710bf76a972b493562e2b6b5

Just a few words on it (more in the README.1st file included): this is a port of The MirBSD Korn Shell R39 to the native WinAPI; it’s not quite got the full Unix feel (especially as it targets the Weihenstephan unxutils instead of a full Interix or Cygwin environment) but doesn’t need a full POSIX emulation layer either. It’s intended to replace MKS ksh and the MKS Toolkit. Source for the compatibility library is also included under The MirOS Licence; we aim at publishing it as OSI Certified Open Source Software like mksh itself. (There is a situation with dlmalloc/nedmalloc being resolved, and the icon is derived from the BSD dæmon which is a protected unregistered trademark, but we’re not Mozilla and allow distro packages to keep using it ☺) Rebasing it on a newer mksh(1) followed by (partial) integration into the main source code is a goal.

Have fun trying it out and hacking on it. It’s currently built with -DMKSH_NOPROSPECTOFWORK (so coprocesses and a few other minor things won’t work), but a SIGCHLD emulation is being worked on – but if you want to help out, I’m sure it’s welcome, just come on IRC or post on the mailing list, and I’ll forward things to Michael as needed. Reports on testing with other toolchain and OS versions are also welcome.

mksh R45 released

26.04.2013 by tg@

The MirBSD Korn Shell R45 has been released today, and R44 has been named the new stable/bugfix-only series. (That’s version 45.1, not 0.45, dear Homebrew/MacOSX packagers.)

Packagers rejoice: the -DMKSH_GCC55009 dance is no longer needed, and even the run-time check for integer division is gone. Why? Because I realised one cannot use signed integers in C, at all, and rewrote the mksh(1) arithmetics code to use unsigned integers only. Special thanks to the people from musl libc and, to some lesser amount, Natureshadow for providing me with ideas what algorithms to replace some functionality with (signed shell arithmetic is, of course, still usable, it is just emulated using unsigned C integers now).

The following entertainment…

	tg@blau:~ $ echo foo >/bar\ baz
	/bin/mksh: can't create /bar baz: Permission denied
	1|tg@blau:~ $ doch
	tg@blau:~ $ cat /bar\ baz
	foo
 

… was provided by Tonnerre Lombard; like Swedish, German has got a number of words that cannot be expressed in English so I feel not up to the task of explaining this to people who don’t know the German word “doch”, just rest assured it calls the last input line (be careful, this is literally a line, so don’t use backslash-newline sequences) using sudo(8).

I uploaded a full bulk build of binary packages for MirBSD/i386 corresponding to the pkgsrc-2013Q1 release. About 7,000 binary packages are available in this build, including the pkgin package manager that makes installing binary packages as easy as apt.

See the pkgsrc page for instructions on how to install pkgsrc for MirBSD. Build logs are available on S3.

mksh R42b and R41c released

Tags: mksh

The MirBSD Korn Shell must-have bugfix releases R42b (for the current formal release series) and R41c (for the last bugfix-only stable series) have been issued. Debian testing/unstable users get the fixes through their package management, versioned 40.9.20120630-7 targetting wheezy (hopefully). Debian experimental users will receive a 42b-1 upload, closer to what other distro packages provide, soonish, targetting jessie.

Since we lack anything better (that, unless Freshmeat, is actually usable), by request of our packagers, new mksh(1) releases will be announced on our miros-mksh@ mailing list starting now.

There is one week left to submit your talk proposals for the BSD devroom at FOSDEM 2013. We still have quite a few slots open, so do not be shy! See the original announcement below:

FOSDEM 2013 will take place on February 2-3, 2013, in Brussels, Belgium. Just like in the last years, there will be both a BSD booth and a developer's room (on Sunday).

The topics of the devroom include all BSD operating systems. Every talk is welcome, from internal hacker discussion to real-world examples and presentations about new and shiny features. The talks will be 45 minutes including discussion. Feel free to ask if you want to have a longer or shorter slot.

If you want to do a talk, please submit your proposal to

bsiegert at google.com

and include the following information:

  • Your name
  • The title of your talk (please be descriptive, as titles will be listed with ~400 from other projects)
  • A short abstract of one to two paragraphs
  • A short biography introducing yourself
  • Links to related websites/blogs etc.

The deadline for submissions is December 17, 2012. The talk committee, consisting of Daniel Seuffert, Marius Nünnerich and Benny Siegert, will consider the proposals. If yours has been accepted, you will be informed by e-mail within one week of the submission deadline.

mksh R41 released

The MirBSD Korn Shell R41 has finally been released. This is a major “everything” version with important fixes as well as new features and behavioural changes. Sorry for the delay.

See also the:

Packages for pkgsrc-2012Q2 are now available on ftp.NetBSD.org. They have been built for MirBSD-current on i386. This time, there is notably a much larger selection of software for X11, due to a successful build of gtk+2. All in all, there are about 6300 packages available.

Interview about MirOS

Tags: news

I (bsiegert@) have been interviewed by OSWorld, a Polish news site about open source software. The interview took place at FOSDEM 2012. I talk about the project, about the community and about some of the great things when using open source. Check out the video.

Read the original article (in Polish) over at OSWorld. Thanks guys!

(Update: Corrected the HTML. Again.

While wtf(1) always has been a bit central to MirBSD, and the acronym database has been accessible by CVSweb, what we never had was a DAU compatible (and shellsnippets compatible) lookup. This has now changed: the above link to the acronyms file is a persistent link to its latest version (well, latest when the website was last recompiled), tooltips may very well follow soon, and we’ve got an online WTF lookup service.
Contributions to the acronym database are welcome, of course; just eMail them to tg@mirbsd.org.

Not to stop there, our online HTML manpage search is also new, shiny, and should replace the “!mbsdman” DuckDuckGo hash-bang shortly. (Both of these services offer a DDG search as fallback. Note that DDG is an external service included herein by linking, under their request to spread it, and not affiliated with The MirOS Project. They do, however, donate some advertising money to Debian.)
For all those who didn’t know: only manpages for software in the MirOS BSD base system and for the MirPorts Framework package tools are listed, not for third-party applications installable using ports or, recently, pkgsrc®. Still, if you want to have a peek at a modern classic BSD’s documentation, you’re welcome. (Not to mention content like re_format(7) and style(9) and that some of our documentation is much more legible than others.)

And because writing all that perl(1) made me ill, not to mention I don’t even know that language, I’ve hacked a bit more in the mirmake(1) and mksh(1) parts of the MirWebsite, finally implementing pointing out where in the navigation sidebar the visitor currently is.

We also have exciting mksh porting news involving RT trying a larger number of ancient platforms than I dare count, me fixing bugs in Linux klibc and diving into other things, learning more about why I consider me lucky for hacking a BSD operating system… sorry, I want to keep this short as it’s mostly an announcement.

The MirWebsite source code is, of course, also available. Improvements welcome. Except for these three CGIs, our website is fully statically precompiled, and that’s a good thing. Please help in making the CGIs secure.

State of the Art (MirBSD-current snapshot)

15.01.2012 by tg@
Tags: snapshot

The current “state of the art” in MirBSD land was just uploaded. This snapshot carries a new patchlevel to show that things happened, such as a bootloader fix for systems with more than one hard disc; but be aware we’re not yet finished with all we think must be done. – The entropyKey software stack has been updated, by the way, and tg@’s shiny new second stick was inaugurated during this build, so it contains Moarrr Entropy™ in addition to e.g. the mksh(1) fix noted on the mailing list.

The MirOS infrastructure servers will be upgraded to patchlevel 10uB0 shortly.
