Adventures in creating new repos / jenkins jobs
by Matthew Walker 05 Mar '14

05 Mar '14

Hey all, I recently had a new repository created; and I wanted to create some jobs for it. I dutifully created and had merged: https://gerrit.wikimedia.org/r/#/c/115968/ https://gerrit.wikimedia.org/r/#/c/115967/ Hashar told me I then needed to follow the instructions on [1] to push the jobs to jenkins. Running the script myself was only pain; it kept erroring out while trying to create the job. Marktraceur managed to create the jobs after much "kicking down the door" aka running the script multiple times. It appears that the problem is that https://integration.mediawiki.org/ci/createItem?name=mwext-FundraisingChart… to https://integration.mediawiki.org/?... So that's a problem? We're still not sure why Mark was able to create the jobs with perseverance though. Another problem that I'm seeing is in responsibilities -- supposedly only jenkins admins (wmf developers) can submit jobs (and then only when it works). And then, only people with root on galium can apply the Zuul configs. To me this is clearly not something the average developer is supposed to be doing. Would it make sense to have QChris / ^demon create the standard jobs when they create the repository?

Drop support for PHP 5.3
by Trevor Parscal 03 Mar '14

03 Mar '14

PHP 5.4 added a few important features[1], namely traits, shorthand array syntax, and function array dereferencing. I've heard that 5.3 is nearing end of life. I propose we drop support for PHP 5.3 soon, if possible. - Trevor [1] http://php.net/manual/en/migration54.new-features.php

captcha idea: proposal for gnome outreach for women 14
by Mansi Gokhale 03 Mar '14

03 Mar '14

hello, These are some approaches i can think of instead of a text based captcha. The image idea where users are asked to spot the odd one out like demonstrated or find all the similar images like mentioned in here<https://www.mediawiki.org/wiki/CAPTCHA> . Also a picture with a part chipped in could be shown and chipped pictures could be given as options like find the missing part from a jigsaw puzzle. The image which would be shown is http://imgur.com/uefeb08 http://imgur.com/KEJqCg3 is the picture which would be the correct option. The other options could be rotated versions of this , which would not be so easy for the bot to match. (unless it somehow worked some digital processing algorithm and matched the color gradients or something like that). This is a good option for people who do not know english or are illiterate and maybe would not understand questions like : is this a bird , plane , superman? after being shown a picture. Tell me what you think (Sorry to upload those images on imgur. i dont know how to put them on the wiki .Hope that is ok) have posted this on the CAPTCHA page<https://www.mediawiki.org/wiki/Talk:CAPTCHA>also

Making it possible to specify MediaWiki compatibility in extensions
by Jeroen De Dauw 01 Mar '14

01 Mar '14

Hey, As you are probably aware of, it has been possible for some time now to install Composer compatible MediaWiki extensions via Composer. Markus Glaser recently wrote an RFC titled "Extension management with Composer" [0]. This RFC mentioned that it is not possible for extensions to specify which version of MediaWiki they are compatible with. After discussing the problem with some people from the Composer community, I created a commit that addresses this pain point [1]. It's been sitting on gerrit getting stale, so some input there is appreciated. [0] https://www.mediawiki.org/wiki/Requests_for_comment/Extension_management_wi… [1] https://gerrit.wikimedia.org/r/#/c/105092/ For your convenience, a copy of the commit message: ~~ Make it possible for extensions to specify which version of MediaWiki they support via Composer. This change allows extensions to specify they depend on a specific version or version range of MediaWiki. This is done by adding the package mediawiki/mediawiki in their composer.json require section. As MediaWiki itself is not a Composer package and is quite far away from becoming one, a workaround was needed, which is provided by this commit. It works as follows. When "composer install" or "composer update" is run, a Composer hook is invoked. This hook programmatically indicates the root package provides MediaWiki, as it indeed does when extensions are installed into MediaWiki. The package link of type "provides" includes the MediaWiki version, which is read from DefaultSettings.php. This functionality has been tested and confirmed to work. One needs a recent Composer version for it to have an effect. The upcoming Composer alpha8 release will suffice. See https://github.com/composer/composer/issues/2520 Tests are included. Composer independent tests will run always, while the Composer specific ones are skipped when Composer is not installed. People that already have a composer.json file in their MediaWiki root directory will need to make the same additions there as this commit makes to composer-json.example. If this is not done, the new behaviour will not work for them (though no existing behaviour will break). The change to the json file has been made in such a way to minimize the likelihood that any future modifications there will be needed. Thanks go to @beausimensen (Sculpin) and @seldaek (Composer) for their support. ~~ I also wrote up a little blog post on the topic: http://www.bn2vs.com/blog/2014/02/15/mediawiki-extensions-to-define-their-m… Cheers -- Jeroen De Dauw http://www.bn2vs.com Don't panic.

Labs migration starts on Tuesday
by Andrew Bogott 01 Mar '14

01 Mar '14

Starting on Tuesday, March 4th, the new Labs install in the eqiad data center will be open for business. Two dramatic things will happen on that day: Wikitech will gain the ability to create instances in eqiad, and wikitech will lose the ability to create new instances in pmtpa. About a month from Tuesday, the pmtpa labs install will be shut down. If you want your project to still be up and running in April, you must take action! We are committed to not destroying any instances or data during the shutdown, but projects that remain untouched by human hands during the next few weeks will be mothballed by staff: the data will be preserved but most likely compressed and archived, and instances will be left in a shutdown state. (Note: Toollabs users can sit tight for a bit; Coren will provide specific migration instructions for you shortly.) I've written a migration guide, here: https://wikitech.wikimedia.org/wiki/Labs_Eqiad_Migration_Howto It's a work in progress, so check back frequently. Please don't hesitate to ask questions on IRC, make suggestions as to guide improvements, or otherwise question this process. Quite a few of the suggested steps in that guide require action on the part of a Labs op -- for that purpose we've created a bugzilla tracking bug, 62042. To add a migration bug that links to the tracker, use this link: https://bugzilla.wikimedia.org/enter_bug.cgi?product=Wikimedia%20Labs&compo… At the very least, please visit this page and edit it with your project migration plans: https://wikitech.wikimedia.org/wiki/Labs_Eqiad_Migration_Progress Projects that have no activity on that page will be early candidates for mothballing. If you want me to delete your project, please note that as well -- that will allow us to free up resources for future projects. I am cautiously optimistic about this migration. Most of our testing has gone fairly well, so a lot of you should find the process smooth and easy. That said, we're all going to be early adopters of this tech, so I appreciate your patience and understanding when inevitable bugs shake out. I look forward to hearing about them on IRC! -Andrew

Two factor auth reset needed on wikitech
by Matthew Walker 28 Feb '14

28 Feb '14

Wikitech admin peoples! I was doing bad things to my phone last night (reflashing it) and I lost the 2 factor auth metadata for my authentication app. Because of this I can no longer log in to wikitech. I wasn't able to find any documentation on wikitech about how to reset it -- so I need your help to do that I think? I still know my password; so I'm not looking to reset that -- maybe just temporarily disable two factor auth on my account (Mwalker) and I'll re-enroll myself? ~Matt Walker Wikimedia Foundation Fundraising Technology Team

CirrusSearch outage Feb 28 ~19:30 UTC
by Nikolas Everett 28 Feb '14

28 Feb '14

CirrusSearch flaked out Feb 28 around 19:30 UTC and I brought it back from the dead around 21:25 UTC. During the time it was flaking out searches that used it (mediawiki.org, wikidata.org, ca.wikipedia.org, and everything in Italian) took a long, long time or failed immediately with a message about this being a temporary problem we're working on fixing. Events: We added four new Elasticserach servers on Rack D (yay) around 18:45 UTC The Elasticsearch cluster started serving simple requests very slowly around 19:30 UTC I was alerted to a search issue on IRC at 20:45 UTC I fixed the offending Elasticsearch servers around 21:25 UTC Query times recovered shortly after that Explanation: We very carefully installed the same version of Elasticsearch and Java as we use on the other machines then used puppet to configure the Elasticsearch machines to join the cluster. It looks like they only picked up half the configuration provided by puppet (/etc/elasticsearch/elasticsearch.yml but not /etc/defaults/elasticsearch). Unfortunately for us that is the bad half to miss because /etc/default/elasticsearch contains the JVM heap settings. The servers came online with the default amount of heap which worked fine until Elasticsearch migrated a sufficiently large index to them. At that point the heap filled up and Java does what it does in that case and spun forever trying to free garbage. It pretty much pegged one CPU and rendered the entire application unresponsive. Unfortunately (again) pegging one CPU isn't that weird for Elasticsearch. It'll do that when it is merging. The application normally stays responsive because the rest of the JVM keeps moving along. That doesn't happen when heap is full. Knocking out one of those machines caused tons of searches to block, presumably waiting for those machine to respond. I'll have to dig around to see if I can find the timeout but we're obviously using the default which in our case is way way way to long. We then filled the pool queue and started rejecting requests to search altogether. When I found the problem all I had to do was kill -9 the Elasticsearch servers and restart them. -9 is required because JVMs don't catch the regular signal if they are too busy garbage collecting. What we're doing to prevent it from happening again: * We're going to monitor the slow query log and have icinga start complaining if it grows very quickly. We normally get a couple of slow queries per day so this shouldn't be too noisy. We're going to also have to monitor error counts, especially once we get more timeouts. ( https://bugzilla.wikimedia.org/show_bug.cgi?id=62077) * We're going to sprinkle more timeouts all over the place. Certainly in Cirrus while waiting on Elasticsearch and figure out how to tell Elasticsearch what the shard timeouts should be as well. ( https://bugzilla.wikimedia.org/show_bug.cgi?id=62079) * We're going to figure out why we only got half the settings. This is complicated because we can't let puppet restart Elasticsearch because Elasticsearch restarts must be done one node at a time. Nik

GSOC 2014 idea
by Roman Zaynetdinov 28 Feb '14

28 Feb '14

Hello, I am willing to participate in GSOC this year for the first time, but I am a little bit worried about choosing the idea, I have one and I am not sure if it suits this program. I will be very glad if you will take a small look at my idea and tell your thoughts. Will be happy to every feedback. Thank you. Project Idea What is the purpose? Help people in reading complex texts by providing inline translation for unknown words. For me as a non-native English speaker student sometimes is hard to read complicated texts or articles, that's why I need to search for translation or description every time. Why not to simplify this and change the flow from translate and understand to translate, learn and understand? How inline translation will appear? While user is reading an article, he could find some unknown words or words with confusing meaning for him. At this point he clicks on the selected word and the inline translation appears. What should be included in inline translation? Thus it is not just a translator, it should include not only one translation, but a couple or more. Also more data can be included such as synonyms, which can be discussed during project completion. >From which source gather the data? Wiktionary is the best candidate, it is an open source and it has a wide database. It also suits for growing your project by adding different languages. Evaluation needs There are two ways in my mind right now. First is to make a web-site built on Node.js with open API for users. Parsoid could be used for parsing data from Wiktionary API which is suitable for Node. A small JavaScript widget is also required for front-end representation. Second is to make a standalone library which can be used alone on other resources as an add-on or in browser extensions. Unfortunately, last option is more confusing for me at this point. Growth opportunities I am leaving in Finland right now and I don't know Finnish as I should to understand locals, therefore this project can be expanded by adding more languages support for helping people like me reading, learning and understanding texts in foreign languages.
