Configure script speedup due to dash for /bin/sh
by Tilman Sauerbeck 29 May '10

29 May '10

Hi, I made /bin/sh point to dash instead of bash and measure how this change speeds up a few randomly picked configure scripts. The speedup achieved is: pkg-config: 2% libarchive: 3% llvm: 7% gcc: 24% coreutils: 17% openssh: 9% htop: 13% Method used: cd /some/tmpfs bsdtar xf /the/package.tar.gz time ./configure # switch /bin/sh symlink rm -rf the-extracted-package bsdtar xf /the/package.tar.gz time ./configure Regards, Tilman -- A: Because it messes up the order in which people normally read text.

prt-get 5.17 uploaded
by Johannes Winkelmann 27 May '10

27 May '10

Hi guys, As discussed in flysprax #581, I've uploaded a new version of prt-get supporting the PKGMK_COMPRESSION_MODE option. There's some room for improvement by caching that value, since right now prt-get will check pkgmk.conf and/or /usr/bin/pkgmk for every package. Compared to the compilation, this time should be neglectable though. For now, I just figured I'd commit/upload the new version, to avoid blocking 2.7 preparation work :-). Cheers, Johannes -- Johannes Winkelmann mailto:jw@smts.ch Zurich, Switzerland http://jw.smts.ch

In my experience there are too many shellscripts out there that start with #!/bin/sh and then expect bash features. I think your findings might be affected by caching, did you take that into consideration? Alan

Replacing tftpd for 2.7?
by Tilman Sauerbeck 25 May '10

25 May '10

Hi, currently, CRUX comes with a TFTP daemon from the iputils package. The manpage says: "It is distributed with iputils mostly as good demo of an interesting feature (MSG_CONFIRM) allowing to boot long images by dumb clients not answering ARP requests until they are finally booted. However, this is full functional and can be used in production." Unfortunately, this version of tftpd only works in combination with inetd. Which is a major annoyance to me, because I don't even have inetd running :) Juergen mentioned that the inetutils package also came with a tftpd, but that one also only works together with inetd. I'd like to propose to change core/iputils so that it doesn't install tftp and tftpd, and instead ask users to install the tftp-hpa port. hpa's tftpd can run both with and without inetd and has a load of other features that I have no idea about ;) tftp-hpa currently lives in contrib, but Thomas is willing to move it to opt if we decide to go ahead with this. Opinions? Regards, Tilman -- A: Because it messes up the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting.

Compression mode patch
by Tilman Sauerbeck 16 May '10

16 May '10

Hi, Juergen came up with a patch that lets users choose what compression scheme to use for packages created by pkgmk. Supported compression algorithms are gzip, bzip2 and xz. I now extended the patch with some text for the pkgmk.conf manpage and renamed PKGMK_COMPRESS_EXT to PKGMK_COMPRESS_MODE (that feels like a better fit to me). To test this patch, you need pkgadd/pkginfo from pkgutils.git (master branch). Otherwise you won't be able to generate footprints/add/etc packages that use bzip2/xz. Please review the patch and if possible, test this new feature. Let me know what you think/find. Thanks, Tilman -- A: Because it messes up the order in which people normally read text.

Proposed: IRC Meeting for 2.7 on 2010-05-04
by JJ Asghar 04 May '10

04 May '10

Traditionally the meetings have been on Tuesdays at 20.00 CET. I propose pushing it back about an hour to 21.00 2010-05-04 CET. I'd like to get all of the developers together so i can fill out the resources and start to track the project. I'd like to look for gaps and a possible roadmap that we can agree for a release schedule. It's not set in stone or anything, but i think if we told the users of our distro to expect it in X days/weeks/months, it would make everyone happy. Also with this type of organization we can leverage other people in the group to test/contrib/hell anything. Thoughts? Best Regards, JJ Asghar phone: 0x1318B7682

Hi folks, JFYI: i've written a little paper on the oss-qm project, which aims to quickly provide fixed sourcetrees to lots of packages+versions and so offload lots of QM/patching works from individual distros to a common place: http://www.metux.de/download/oss-qm-project-2010050101.pdf cu -- ---------------------------------------------------------------------- Enrico Weigelt, metux IT service -- http://www.metux.de/ phone: +49 36207 519931 email: weigelt(a)metux.de mobile: +49 174 7066481 icq: 210169427 skype: nekrad666 ---------------------------------------------------------------------- Embedded-Linux / Portierung / Opensource-QM / Verteilte Systeme ----------------------------------------------------------------------
