pbzip2 proposal
by Richard Jelinek 16 Jan '16

16 Jan '16

Hi, don't know if this issue came up already - in case it did and has been dismissed, I beg your pardon. In case it didn't... I hereby propose, that pbzip2 (https://launchpad.net/pbzip2) is used to compress the xml dumps instead of bzip2. Why? Because its sibling (pbunzip2) has a bug bunzip2 hasn't. :-) Strange? Read on. A few hours ago, I filed a bug report for pbzip2 (see https://bugs.launchpad.net/pbzip2/+bug/922804) together with some test results done even some few hours before that. The results indicate that: bzip2 and pbzip2 are vice-versa compatible each one can create archives, the other one can read. But if it is for uncomressing, only pbzip2 compressed archives are good for pbunzip2. I propose compressing the archives with pbzip2 for the following reasons: 1) If your archiving machines are SMP systems this could lead to a better usage of system ressources (i.e. faster compression). 2) Compression with pbzip2 is harmless for regular users of bunzip2, so everything should run for these people as usual. 3) pbzip2-compressed archives can be uncompressed with pbunzip2 with a speedup that scales nearly linearly with the number of CPUs in the host. So to sum up: It's a no loose and two win situation if you migrate to pbzip2. And that just because pbunzip2 is slightly buggy. Isn't that interesting? :-) cheers, -- Dipl.-Inf. Univ. Richard C.

scheduling reboot / maintenance on dumps server
by Ariel T. Glenn 30 May '12

30 May '12

We've seen some kernel errors in the logs on the server that hosts the dumps. In order to upgrade and reboot, we need the currrently running dumps to exit as soon as they complete the current phase of their runs. I expect to complete this before the end of the week; if necessary I will shoot existing processes to get it done. In the meantime as dumps complete, new ones will not be started; thanks for your patience. Ariel

minor deployment script update (runners will stop and be restarted)
by Ariel T. Glenn 25 May '12

25 May '12

Over the next few days you'll see the number of processes drop as jobs on each host complete. I'll be restarting themon each host as they finish; this is part of my work to get deployment to suck less. Ariel

Last English Wikipedia dump in a single file
by emijrp 23 May '12

23 May '12

Hi; I remember that here[1] there was a 7z file with one of the last (or the last one) English Wikipedia dump (in a single file). Where is it? Regards, emijrp [1] http://dumps.wikimedia.org/enwiki/20100130/ -- Emilio J. Rodríguez-Posada.

XML dumps/Media mirrors update
by Ariel T. Glenn 21 May '12

21 May '12

We now have three mirror sites, yay! The full list is linked to from http://dumps.wikimedia.org/ and is also available at http://meta.wikimedia.org/wiki/Mirroring_Wikimedia_project_XML_dumps#Curren… Summarizing, we have: C3L (Brazil) with the last 5 good known dumps, Masaryk University (Czech Republic) with the last 5 known good dumps, Your.org (USA) with the complete archive of dumps, and for the latest version of uploaded media, Your.org with http/ftp/rsync access. Thanks to Carlos, Kevin and Yenya respectively at the above sites for volunteering space, time and effort to make this happen. As people noticed earlier, a series of media tarballs per-project (excluding commons) is being generated. As soon as the first run of these is complete we'll announce its location and start generating them on a semi-regular basis. As we've been getting the bugs out of the mirroring setup, it is getting easier to add new locations. Know anyone interested? Please let us know; we would love to have them. Ariel

Hello, there seems to be only two worker processes for bigger wikis instead of three as before. Best regards Andreas

Picture of the year
by burslem 08 May '12

08 May '12

It's amazing there are already so many years available for download. Especially the larger zips must have been somewhat time-consuming to compile! It would be great if 2008 or pre-2006 packages become available in the near future. It is a really interesting development to see http://dumps.wikimedia.org being interested in not only compiling large current packaged databases of various wikis, but also more historic content. In the past, the Internet Archive was the sole distributor of older (also historic) wiki packages. Eventually in the far future, there will have to be some sort of viable mechanism for cloning all the images stored on wikimedia, though as for now the Picture of the Year packages are very interesting for those more interested in the pretty images of wikipedia. The POTY images also make great wallpaper packs!
