’M back.

21.03.2011 by tg@

Two DNF out of four geocaches, well… one was too muggled, the other was no longer there, judging from the previous visitors’ log entries. Cached with natureshadow and bought his book on how not to cycle across Germany.

CLT was a blast, and it’s refreshing to attend an event without having to drive a booth of our own. Talked to lots of people. Since the boss was paying, even did some mingling in that area.

My ADSL line has been hiccupping ☹

Yawn.

Will drive to Chemnitz now. Maybe meet me there. No booth, just visiting to meet everyone again, rather spontaneous.

Rhonda suggested I document how to use the LLS (Launchpad Login Service – their implementation of an OpenID provider) as Delegate, which basically means, you can put something up on your webpage, which can be a simple static (X)HTML page like mine (a /index.htm is especially nice, a /~user/index.htm works too), and use its URI and not https://launchpad.net/~me to login. For example, this often hides the LLS from view e.g. in blog comments, such as those where Canonical is being criticised ☺ – but it’s also yours, easier to type and to change if you switch service providers.

The basic idea is to go to your Launchpad user page and view its page source. Look for openid relation links in the header – on Rhonda’s the value we’re looking for is “cyLQbcp”, and you see it several times.

Now you put this on your web page:

	<!-- begin: OpenID delegation to LP -->
	 <link rel="openid.server" href="https://login.launchpad.net/+openid" />
	 <link rel="openid.delegate" href="https://login.launchpad.net/+id/cyLQbcp" />
	 <link rel="openid2.provider" href="https://login.launchpad.net/+openid" />
	 <link rel="openid2.local_id" href="https://login.launchpad.net/+id/cyLQbcp" />
	<!-- end: OpenID delegation -->
 

Of course, insert your, not Rhonda’s, ID. Do note that we don’t copy the X-XRDS-Location tag (that breaks things for some unknown reason), but otherwise, what we insert on our page is pretty much a copy of the info on the user page (maybe it’s a Delegate page, too?).

As usual, try at your own risk, bug Canonical if it breaks. It works with AO3, Gerrit Code Review, and others though (interestingly enough, better in Lynx than GUI browsers because I stay logged in across Lynx sessions (and just have to confirm sending “my information” to the accessing site), whereas I have to re-login to the LLS in every GUI browser session).

As with the LLS generally, “to access a site which is not recognised” is expected and worked on with low urgency (mostly cosmetical, I think).

mksh-current has just gained an experimental recursive parser for command substitutions, fixing RedHat BZ#496791 and decades-old complaints about the pdksh codebase, compared to AT&T ksh93. (GNU bash could also do the example, but not some other things mksh(1) parses fine now.)

This means that things like the following work now.

	# POSIX, should “always” work
	echo $(case 1 in (1) echo yes;; (2) echo no;; esac)
	# POSIX optional, works now in mksh, works in GNU bash
	echo $(case 1 in 1) echo yes;; 2) echo no;; esac)
	# GNU bash seems to choke on comments ending with backslash
	# a comment with " ' \
	x=$(
	echo yes
	# a comment with " ' \
	)
	# No non-recursive COMSUB parser can pass all of the above
	# tests and these below at the same time (some extensions)
	echo $(typeset -i10 x=16#20; echo $x)
	echo $(typeset -Uui16 x=16#$(id -u)
	) .
	echo $(c=1; d=1
	typeset -Uui16 a=36#foo; c=2
	typeset -Uui16 b=36 #foo; d=2
	echo $a $b $c $d)
	# the ‘#’ is especially tricky, that’s why the above cases
 

Next on my TODO is the complete rewrite of the read built-in command, as well as its documentation. I think that the (reduced) goals for mksh R40 will have been met by then, except porting to LynxOS and MPE, but we’re working on it, and re-testing Syllable and Plan 9). Of course, a release implies testing on a lot of the supposedly supported platforms, so it won’t be out “immediately”. Though, associative arrays have been removed from the R40 goals, so that I can at least get a new release out. Note that Debian and OpenSuSE Buildservice users have been provided with somewhat well-tested mksh-current snapshots for a while already, and Gentoo users can use the “live ebuild”; there’s always compiling from source too…

(Free)BSD vs. Linux

Warning: this is a rant against BSD (specifically FreeBSD®, but don’t let me get started on DragonFly, who think it’s wise to drop all shells except ash from the base system and rely on pkgsrc® – yay let’s compile a dozen packages just to get a shell with tab completion, not to mention boxen with no network access – for the task – although others seem to go into that direction too…; you know, there’s BSD, and then there’s FreeBSD…) – don’t like, don’t read.

If you want to change something in the BSD world, you gotta fork your own BSD – no other way around the thickheads. Ok, back then, I ran into a particularily thick one, but others tend to not be much better. Users share the thickness. If you want to change something in the GNU/Linux world, just make a package, have someone upload it, prod (or pay, Hanno got a Radler) people to do it, or just upload it yourself.

At the BSD booth at FOSDEM, despite me bringing the Windows® Mobile 6 Professional devive, strictly for Geocaching mind you, Macintosh boxen had a share of more than 50% – I didn’t manage to tip the scale. At the Debian booth, almost everyone had a “I want to buy a new laptop some day, but it just keeps on working and doesn’t break” pre-Lenovo IBM laptop. No hyping of Google either. (Last year’s CLT saw BSD people advocating pro-Schily – the guy with the broken encoding in his name – shockingly.)

Honestly, tcsh, FreeBSD® people? Sorry. While I agree that there is merit on having the same script and interactive shell, as someone has pointed out (copy-paste examples into the command line), there’s those zsh users who use mksh or GNU bash for scripting. Or just POSIX shell. And that’s with an interactive shell which can be used for scripting. On the other hand, the C shell (both csh and tcsh) cannot.

And what’s with pretending the accent gravis is non-combining, called “backtick” (such a thing does not exist); and advocating it? Sorry, if your csh/tcsh doesn’t handle the POSIX $(…) you should just drop it. (By the way, there is a convention that example command lines are prefixed with for csh and for sh (or but we write $ sudo  instead, these days). Use it. Or leave it. If you have examples that substitute another process’ output, be specific.) It’s funny to see how one person tries to defuse my arguments against csh by telling me “it’s just an interactive shell”, while the other argues that people copy-paste between them, to which that was my response. Read the thread!

And please, get your facts right. “I would prefer that the standard shell be at least Bourne-compatible.” You don’t want Bourne (“^” instead of “|” for pipes), you want POSIX. That GNU bash is called the Bourne-Again Shell in one of their usual semi-bad puns doesn’t help the global perception of such things any. Also, the root shell and /bin/sh are disjunct.

(Plus, why change the root shell, use sudo(8), plain and simple.)

ObNote: in jupp (should I package that for Debian, btw? rather upload, packages are ready…) the ‘`’ key is used as præfix for Ctrl-X (`X) or to directly enter numerical (decimal, octal, sedecimal/hexadecadic) ASCII, 8-bit or Unicode codepoints. Yay!
And even the FSF has seen the light; for a few releases already, GCC uses “'…'” instead of “`…'” for quoting in messages, even without locales. Great job there! (LC_MESSAGES=en_GB.UTF-8 usually works, too, though.)

ObDisclaimer: I have an (yes, Google…) Alert on the word “mksh”, so I know when it’s being discussed. This obviously includes certain fora. Also, I’m a shell implementer and bound to know a certain amount of details. Plus, mksh’s build script runs with pretty much any Bourne/POSIX/Z Shell which has functions and not too many bugs. I wrote it. Go figure. No lowly trolling.

FWIW, mksh(1) has the cat(1) builtin both because Android has no cat(1), and as speed hack. Almost all other shells have worse speed hacks, like a printf(1) builtin. And recently, builtins have become direct-callable, so this actually reduces the overall system footprint. (Its inclusion also provides for some other possibilities, internally.) And as two final side notes, if you haven’t seen this: determine which shell we are run under (CVS) and I still offer a prompt conversion service (send me any GNU bash or oksh $PS1 and I’ll send that to you in mksh(1) syntax – optionally with adjustments/improvements, like cwd uses only up to 1/3 of screen width).

Eh. Why does mksh built with (a patched: mkstemp(3) added) klibc work suddenly, unexpectedly?

To reproduce, I just uploaded mksh_39.3.20110218-1.dsc and you can run DEB_BUILD_OPTIONS=mksh-static=klibc,dietlibc,eglibc dpkg-buildpackage -rfakeroot to verify it, once you have mkstemp(3). (I will probably send a smaller implementation of that in, later.) I have that and the open fix and the m68k patch applied, nothing else… where did my bug go?

ObQuestion: what’s the legal (copyright/trademark) status of the Atari logo (the one in rainbow colours, with three things going up, right and left “leg” looking like an umbrella stand’s)?

FOSDEM was a blast!

13.02.2011 by tg@

I just need to work more on bilocality. While I did find two geocaches, one at the South/Noon Train Station (taalverwarringen…), one in the buurt of the University, I did manage to miss the AW building completely and utterly. Wow. Except, that Haiku guy came over to talk for a bit (nice). And I drew. An Atari logo with swirl, for that weird stuff I recently have been found doing.

More mksh-current news coming soon, stay tuned. In the meanwhile, I met bonsaikitten IRL (at FOSDEM, yes, too) who kindly made a “live ebuild”, i.e. a source package building -current.

Finally let’s say a big thank you to the person mostly manning our booth, gecko2, and to Benny for talking to people, getting That Other Packaging Thingy working, and pimping the website a bit.

On SecureAPT

Dear Opera Software A.S.A.

It’s nice that you employ SecureAPT for your package repository, however, the effect is slightly lost by you replacing the key each year, never signing any of them, and putting them up on an http but not https site.

Update 18.08.2011 – please refrain from putting a file /etc/apt/sources.d/opera.list inside your binary DEB packages, as well. As a system administrator, we may very well have mirrored the binary packages, and do not want accesses to external APT repos, for a shitload of reasons. Honestly. (Lintian could warn about it…)

If you don’t get the message, please contact me. Or any of my fellow Debian Developers. Thank you very much.

FOSDEM, the Free and Open Source Software Developers' European Meeting

❧ Who’s not? ☺ Same procedure as every year.

(okay, lolando prefers skiïng but…)

Anyway. A cow‐orker told me that Belgium again/still has no gouvernment, and they have been asked to grow out their beards until they do. I found “evidence” on the ’net but won’t link it here, also it’s on German… anyway. Let’s all join in. (Besides, I now have an excuse to not shave, maybe even my grandmother will accept this one…)

RT said on IRC that mksh will probably work on MSYS.

My Debian/m68k stuff is coming around nicely, but I still haven’t gotten around to do everything planned, plus I need to grow a new kernel and eglibc, after the latest uploads, and the 2.6.37 based one panics. Also I’ve got to take care to not overwork myself. (And make a MirBSD ISO for FOSDEM.) But hey, it’s been not working for some time and better now. And slow anyway ☺ yet we’re progressing. Does anyone know how to debug that a C programme only calling res_init(3) segfaults?

Benny is apparently not just working on making NetBSD® pkgsrc® available on MirOS BSD (picking up my work from 4+ years ago) but also replacing The MirPorts Framework with it. Sad, as I got a request for a gajim MirPort over a cocktail just this evening…

When doing porter uploads, one must not forget to pass -m"My Name <my@email.addr>" to dpkg-buildpackage, e.g. with --debbuildopts for cowbuilder. Thanks Aurélien and sorry to everyone who got the upload mails.

(How are the rules for sponsored uploads? I get conflicting info on these, and indeed, the one I sponsored never showed up on my QA DDPO page…)

I’m almost finished with “sort of re-bootstrapping” Debian/m68k (I can use etch-m68k as well as what was in unstable at the moment as dependencies, so it was not that much, still, 305 binary packages build from 84 source packages, most for unstable (very few for unreleased, with very responsive maintainers, thanks all, who will include the patches in their next uploads) is a bit… including rebuilds with newer versions, more patches, more testing or newer dependencies installed. I’ll probably upload on Sunday evening, as I’ll be off for 2-4 days at least from then (see below). Ingo tried to test on real hardware, but as Murphy wants a hard disc failed… we’ll still try to get something done over the weekend. If you want to have a look, see my repository index (sources.txt contains a sample sources.list file, 0-NOTE.txt some hints, including the right debootstrap/cowbuilder magic and speed tricks). I’ll need to learn how to use LVM and set up a buildd now…

I’ve not been in much of a hacking mood recently – all these visits to the dentist leave me in unrest and disturb my equilibrium. Hence, not much activity even in mksh even if there was need, almost none in MirBSD. This is only temporary, but I won’t attend OpenRheinRuhr, or, if I come at all, it’ll be for socialising only and probably only one day. Benny’s done with his Doctor (in France, no idea whether it’s one in Germany as well) of Chemistry and has returned to hacking some (World of) Google-Go(o) code. I expect MirBSD activity to slowly raise once we can come back. Please accept our apologies.

I’m currently working on something which will eventually amount to a re-bootstrapping of sorts of the Debian/m68k (Linux) port – patches to the Linux kernel, gcc, etc. are prepared (some have been accepted into upstream or the packages already). I will probably have more, once the compile processes finish, anyway (even emulated, it’s slow).

I think that, once I get past that TLS (thread-local storage, needed by eglibc) migration, I will try to find out a list of packages needed for debootstrap (AFAICT: all packages marked Essential, or of priority important, and all marked Build-Essential (for the *-builder variant), and their dependencies (although I’ll substitute sysv-rc with file-rc, which is better and needs less deps)) and pull arch:all from sid, then build the rest myself using a consistent snapshot of sid possibly with patches going to unreleased. Then I can use cowbuilder to make cleaner packages, which can eventually be uploaded (once I get enough to get a buildd running – kernel, bootloader, etc) – binNMUs are way to go here I suppose. I will only upload once it’s self-hosted, installable (seen by edos-debcheck), clean, etc. (i.e. I’ll rebuild all binaries) and probably keep a bootstrap repo around (until m68k caught up) so that unstable (possibly amended by unreleased for a while) will not again become uninstallable, e.g. if arch:all packages change their dependencies (Python, gcc-defaults are some I’ve seen). That bootstrap repository is needed anyway because debootstrap can’t install from two separate repositories (unstable+unreleased for example).

Progress is slow because I try to keep as close to official packages as possible, refuse to cross-compile, and try to produce uploadable if possible packages all the time. Getting patches into packages, so that I can build from unstable, instead of debian-ports.org unreleased, has proven time-consuming and occasionally frustrating as well. Although I would like to thank the people who helped me on the way already. (I am not naming any in fear of forgetting some, but you know who you are ☺) They are among the Debian (gcc, kernel, m68k) and Linux-68k crowd.

(Why does genattrtab in gcc-4.4 take 3½ hours when it took less than half an hour in gcc-4.3 anyway?)

I’m also still working on mksh and some Python ISO hacks for mika and some minor stuff, and further cleaning up MirBSD.

Well, did I mention dentists are sadists?
