Guest Blog: Rares Aioanei – Kernel Weekly Review with openSUSE Flavor

July 3rd, 2010 by

Hello, and be welcome to the 12th edition of the Weekly Kernel News!

-The first news for this week is Jan Kara’s pull request fot linux-fs (ext2 and ext3 in our case) aimed at -rc4, Frederic Weisbecker posting his pull request for the perf tree and Arnaldo Carvalho de Melo’s pull request for perf/core targetted at 2.6.36 .

-Sticking to the pull requests, we have also Dmitry Torokhov posting input updates for 2.6.35-rc1, Trond Myklebust with NFS client improvements, Tejun Heo with two fixes for the percpu tree and David Miller with networking fixes , quite a few of them, since they accumulated during Linus’ vacation, as the author explains.

-Neil Brown posted a pull request related to md, targetted @ 2.6.35, containing  various bugfixes, Thomas Gleixner posted various fixes for the core, x86, timer, scheduler, genirq and perf trees targetting also 2.6.35, Jens Axboe also has a pull request for  the block/IO subsystem (targetting -rc*) and Steven Rostedt posted a pull request for the tracing/perf/core tree aimed at 2.6.36 .

-Jeffrey Merkey posted an announcement of MDB Merkey’s Kernel Debugger x86_64 2.6.34 06-28-2010,  with the following summary : “http://merkeydebugger.googlecode.com/files/mdb-2.6.34-x86_64-06-28-2010.patch

This is the first full x86_64 version of MDB.  This implementation of MDB also uses the x86_64 and IA32 versions of the GDB disassmbler instead of the older IA32 disassembler from previous version of MDB.  bfd has been integrated into MDB which will support easy porting of MDB to other processor types.  I used the kdb disassembler GDB source base and added all the MDB features and layout (intel style).  This version also supports 8086 disassembly and IA32.  There is a short list of items left on the list and I will update these as I have more time to work on MDB.” Following is a list of fixes and todo’s, go check them out if interested.

-Junio C Hamano announced the release of git 1.7.11, which can be downloaded at http://www.kernel.org/pub/software/scm/git/ , and that is where one can also find RPM packages. The fixes list is too long to be posted here, but you can always check it out via web.

-Jeffrey Merkey comes back with the release of his MDB (see above) dated 29.06.2010,  introducing a few fixes :
“- fixed DS and W commands to output qwords in stack argument dump
– add find_extend_vma and follow_page to exported symbols
– add ds: and es: segment lookups in disassembler
– enable .TM flag to toggle memory read between physical and user space read/write for addresses < PAGE_OFFSET”

-Tony Lindgren asks Linus for the usual pull, in this case pertaining to omap fixes for 2.6.35-rc3, OpenSUSE’s own Greg Kroah Hartman posted a series of patches related to USB, staging and serial for 2.6.35-git, Dave Airlie posted fixes for drm, agp and fb, all part of the drm tree, John W. Linville posted some wireless fixes for 2.6.35 and Wim Van Sebroeck posted a pull request for the watchdog tree that introduces a  documentation fixi (for -rc3).

-Karel Zak announces the release of util-linux-ng v2.18 (stable) which you can download from the usual location : ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/v2.18/ .

-Junio C Hamano announced git 1.7.2.rc1 , available at the same URL as above, make sure you check it out or just update your distro.

-The vhost-net tree was updated by a pull request by Michael S. Tsirkin, asking to merge the tree for 2.6.35, while Jeff Garzik updated the libata tree with a few fixes and Paul McKenney updated the rcu tree with a revert commit, while Thomas Gleixner posted a pull request for the sched tree.

-Greg Kroah Hartman started a series of 149 patches as part of the review cycle of 2.6.32.16 : “This is the start of the stable review cycle for the 2.6.32.16 release. There are 149 patches in this series, all will be posted as a response to this one.  If anyone has any issues with these being applied, please let me know.  If anyone is a maintainer of the proper subsystem, and wants to add a Signed-off-by: line to the patch, please respond with it.

Responses should be made by Sat, July 3, 17:00:00 UTC UTC. Anything received after that time might be too late.

The whole patch series can be found in one patch at: kernel.org/pub/linux/kernel/v2.6/stable-review/patch-2.6.32.16-rc1.gz and the diffstat can be found below.” Greg also started posting the same series of patches, this time for 2.6.27.48, 2.6.33.6, 2.6.34.1 .

That’s all, folks! Have a sunny weekend!

Guest Blog: Rares Aioanei – Weekly Review of PostgreSQL with openSUSE Flavor

July 3rd, 2010 by

Hello, everyone, and welcome to this week’s PostgreSQL News, issue 130!

-Josh Berkus made an official announcement related to 7.4 and 8.0 becoming EOS (End-Of-Support) : “The next bugfix or security update release for PostgreSQL versions 7.4 and 8.0 will be the last updates for those versions. This is in accord with the PostgreSQL Release Support Policy announced in December. We urge users still using 7.4 or 8.0 in production to begin planning migration to newer versions immediately.

Version 8.1 will stop being updated in November, so users of version 8.1 should be planning an upgrade this year.

While we regret the inconvenience to some PostgreSQL users, the community has limited resources and time spend maintaining old versions of PostgreSQL reduces the time we have to develop new features.  Users who are unable to upgrade their PostgreSQL installations will need to make their own plans for backporting patches, possibly with the help of a commercial PostgreSQL support provider.”

-Steve Singer announced the release of Slony-I 2.0.4 , which introduces  some fixes to issues introduced by 2.0.3 . http://www.slony.info is the address you need 🙂

-Josh Berkus wrote on hackers@, proposing that the release date of beta3 will be July the 8th, in order to give American contributors enough time to recover after their national holiday. After discussions and oppinion exchanges, we should expect the release of the 3rd beta in the first half of July.

-In Planet PostgreSQL we have Bruce Momijan talking about PostgreSQL 9.0 Illustrated, which is a easier way to understand what to expect in the new release, so if you feel confused by the release notes, use this link : http://wiki.postgresql.org/wiki/Illustrated_9_0

-Leo Hsu and Regina Obe talk about importing data into PostgreSQL using OpenOffice Base 3.2; look it up here : http://www.postgresonline.com/journal/index.php?/archives/167-Importing-data-into PostgreSQL-using-Open-Office-Base-3.2.html#extended .  Since the authors’ native tongue isn’t English, you may encounter some language-related flaws, but other than that, it’s an article worth reading. 🙂

-Finally, we try to summarise the PostgreSQL Weekly News (the official news, that is) :

-This week sees the release of Benetl v3.5, an ETL tool for files using PostgreSQL.
-Muldis-D 0.130.0, a specification for an object-relational language intended to run atop, among other systems, PostgreSQL, is released.
-Except these news, and the ones we’ve already talked about, this week is again kinda poor in news. For the usual list of patches, accepted, rejected and pending, check the weekly news.

That’s it for me, see you next week with hopefully more interesting news!
