Fwd: [Wikitech-l] Deploying Swift for thumbnails next Mon-Thurs Feb 6-9

Forwarded per Ben's request. ---------- Forwarded message ---------- From: Ben Hartshorne <bhartshorne(a)wikimedia.org> Date: Tue, Jan 31, 2012 at 8:43 PM Subject: [Wikitech-l] Deploying Swift for thumbnails next Mon-Thurs Feb 6-9 To: Wikimedia developers <wikitech-l(a)lists.wikimedia.org> Hi Everyone, Next week we're going to switch the back end system that hosts thumbnail[1] images. We have been using ms5<http://ganglia.wikimedia.org/latest/?r=day&cs=&ce=&m=&c=Miscellaneous+pmtpa…>(a Sun server running linux) to serve all thumbnails. We are switching to Openstack Swift <http://wikitech.wikimedia.org/view/Swift>, a clustered object store. Though we have done testing and expect no problems, I want to publicize the change so that if issues do appear, they are quickly directed to the right place. Here's the schedule: * Monday Feb 6th: move 0.4% of all thumbnail traffic from ms5 to swift. Only thumbnails with "/thumb/a/a2/"[2] in the URL will be affected. * Tuesday: move 12.5% of traffic - thumbnails with "/thumb/a/" or "/thumb/b/" will be affected * Wednesday: move 50% of traffic - thumbnails with "/thumb/(a-f or 0 or 1)/" will be affected * Thundlay: move 100% of traffic - all thumbnails will be served from Swift Potential symptoms that might be related to this change on Monday: * a thumbnail image with /a/a2/ simply fails to load ** try changing the number preceding 'px' to generate a different size image[3] * you delete an image and the thumbnail is still available ** try purging the cache[4] and see if that makes it go away ** try changing the number preceding 'px' and see what happens * you move an image to a new name and it's still available at the old name, when either the new or old name has /a/a2/ in the URL ** please provide full URLs for both the new and old names If any of these things happen, or if something else odd happens with images or thumbnails and you feel it might be related, please join #wikimedia-tech in IRC and ping me (maplebed) or Aaron (AaronSchulz). If neither of us are available or you would prefer to just leave us a message, add a note to https://www.mediawiki.org/wiki/SwiftMedia/Issues. :) If things are severely broken, you can ask someone in the #wikimedia-tech to page me. Thanks for your help! -ben [1] In case you don't know what I mean by thumbnail images, I'm talking about all URLs that start http://upload.wikimedia.org/ and have /thumb/ in the path. When an image is uploaded to a wiki (or commons), Mediawiki automatically generates scaled versions of the image. These are what I call 'thumbnails'. Nearly every time an image is used in a wiki page it is actually a thumbnail being used. Try going to any wiki page with an image, right click on the image, and choose 'view image'. You'll get something like http://upload.wikimedia.org/wikipedia/commons/thumb/4/45/Liberty_Head_Nicke… as the URL (this was taken from enwiki's featured article today) [2] For example, http://upload.wikimedia.org/wikipedia/commons*/thumb/a/a2/*Little_kitten_.j… [6] [3] For example, http://upload.wikimedia.org/wikipedia/commons/thumb/a/a2/Little_kitten_.jpg/ *799px*-Little_kitten_.jpg [4] Find the URL for the main image file (rearrange the URL to find the original image - /wikipedia/commons -> commons.wikipedia.org) and add "?action=purge" to the end of the URL (eg http://commons.wikimedia.org/wiki/File:Little_kitten_.jpg?action=purge [5] Image in the public domain [6] cc-by 3.0, Alexanderwdark<http://commons.wikimedia.org/w/index.php?title=User:Alexanderwdark&action=e…> _______________________________________________ Wikitech-l mailing list Wikitech-l(a)lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l -- Guillaume Paumier Technical Communications Manager — Wikimedia Foundation

Actually, just asking in #wikimedia-labs, there's an high probability that someone with appropiate permissions will be there.

The developers of MediaWiki, the software Wikimedia sites run on, are wrapping up work on a new version, with hundreds of improvements and bugfixes. Description: https://www.mediawiki.org/wiki/MediaWiki_1.19 There is a draft schedule for deploying this software to all Wikimedia sites in February and March. The schedule is tentative and dates are going to shift and change. (See the "SCHEDULING" note below in this email.) https://www.mediawiki.org/wiki/MediaWiki_1.19/Roadmap We want to do a lot of testing BEFORE the rollout, so that we catch potential problems before they affect readers and editors. Please help us! We have set up replicas of your wikis and installed the latest MediaWiki code on those replicas, so you can spot new problems in the software's behavior: http://labs.wikimedia.beta.wmflabs.org Please look at http://labs.wikimedia.beta.wmflabs.org/wiki/Special:SiteMatrix and find wikis to test. Try reading, editing, and so on as you normally would; treat it as a giant sandbox. If you find a problem, please report it here: http://labs.wikimedia.beta.wmflabs.org/wiki/Problem_reports We are especially interested in finding out about problems that affect unique JavaScript user scripts or Gadgets, so we can help you fix them. SCHEDULING: Now is also a good time to let us know if there are going to be big news days or weeks in February where your community would be especially unhappy if you had a window with no access or no editability. For example, if there's an important national election happening in one of the countries you serve, we'd ideally like to avoid taking your site down for maintenance on that day. https://www.mediawiki.org/wiki/Talk:MediaWiki_1.19/Roadmap would be a good place to tell us that. If you have questions, please feel free to contact us in https://www.mediawiki.org/wiki/MediaWiki_on_IRC or via the Wikimedia developers' mailing list at https://lists.wikimedia.org/mailman/listinfo/wikitech-l .

I want to let you know of a new feature we now have on Wikimedia sites. Please publicize this to wikis, and ask them for suggestions and criticism, and pass that information along to Max. Thank you. -- Sumana Harihareswara Volunteer Development Coordinator Wikimedia Foundation -------- Original Message -------- Subject: [Wikitech-l] FeaturedFeeds deployed Date: Thu, 26 Jan 2012 17:06:16 +0400 From: Max Semenik <maxsem.wiki(a)gmail.com> Reply-To: Max Semenik <maxsem.wiki(a)gmail.com>, Wikimedia developers <wikitech-l(a)lists.wikimedia.org> To: Wikimedia developers <wikitech-l(a)lists.wikimedia.org> Yesterday we deployed FeaturedFeeds[1] to the cluster (thanks, Arthur!) Everything looks good so far, examples of feeds: [2], [3]. We haven't enabled feed links in the sidebar like on our staging wiki at [4] - I wonder if we should enable them on opt-in or opt-out basis. Overall, I'd apreciate your critics, comments, suggestions. Also, please assist your local communities in seting up their feeds, especially if you know less common languages. --- [1] https://blog.wikimedia.org/2012/01/26/featuredfeeds-brings-syndication-feed… [2] https://en.wikipedia.org/w/api.php?action=featuredfeed&feed=featured&feedfo… [3] https://it.wikiquote.org/w/api.php?action=featuredfeed&feed=qotd&feedformat… [4] http://mobile-feeds.wmflabs.org/w/index.php/Main_Page -- Best regards, Max Semenik ([[User:MaxSem]]) _______________________________________________ Wikitech-l mailing list Wikitech-l(a)lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l

Blackout of English Wikipedia on 18 January
by Sumana Harihareswara 16 Jan '12

16 Jan '12

https://blog.wikimedia.org/2012/01/16/wikipedias-community-calls-for-anti-s… "...the Wikipedia community has decided to black out the English-language Wikipedia for 24 hours, worldwide, beginning at 05:00 UTC on Wednesday, January 18. The blackout is a protest against proposed legislation in the United States —the Stop Online Piracy Act (SOPA) in the U.S. House of Representatives, and the PROTECTIP Act (PIPA) in the U.S. Senate— that, if passed, would seriously damage the free and open Internet, including Wikipedia....." We'll be disabling editing via the web service API. You can ask questions regarding the planning in #wikimedia-sopa . -- Sumana Harihareswara Volunteer Development Coordinator Wikimedia Foundation

Fwd: [Wikitech-l] Mailing lists server migration today

-------- Original Message -------- Subject: [Wikitech-l] Mailing lists server migration today Date: Fri, 13 Jan 2012 14:54:00 +0100 From: Mark Bergsma <mark(a)wikimedia.org> Reply-To: Wikimedia developers <wikitech-l(a)lists.wikimedia.org> To: Wikimedia developers <wikitech-l(a)lists.wikimedia.org>, Wikimedia Foundation Mailing List <foundation-l(a)lists.wikimedia.org> Hi, Today I will be migrating the mailing lists from a very old server (lily) in Amsterdam, to a new server (sodium) in our new Ashburn data center. Mailman will be upgraded to version 2.1.13 along the way. During the migration, mail will be delayed as all data will need to be transferred to the new host. No mail should go lost, but no new mails will be sent out during the process until done, and the web interface will be unavailable. This shouldn't take more than one hour, if all goes well. I will report here when things should be back up and running. Afterwards, please let us know of any new issues, in bugzilla or on IRC (#wikimedia-tech). We don't expect any problems, but as with any software upgrade or migration, this can't be guaranteed... Thanks, -- Mark Bergsma <mark(a)wikimedia.org> Lead Operations Architect Wikimedia Foundation _______________________________________________ Wikitech-l mailing list Wikitech-l(a)lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l

Fwd: [Wikitech-l] CANCELED: Mailing lists server migration today

Mailman will be upgraded to version 2.1.13 along the way. ...and right after I sent this mail, I rebooted the new server once more before starting the maintenance. But suddenly it refused to come back up, or even reinstall. Likely the server has hardware issues. Therefore the maintenance is canceled for today, until we've figured out what the problem is. The migration will probably happen next week, possibly using different hardware. -- Mark Bergsma <mark(a)wikimedia.org> Lead Operations Architect Wikimedia Foundation
