UNIQ[…]QINU exposed to anonymous users
by Andru Vallance 08 Apr '13

08 Apr '13

I've recently been battling a painful bug on http://practicalplants.org, whereby all Cite <refs> were left as unsubstituted UNIQ…QINU tags for anonymous users, when anonymous editing is disabled, and additionally a "You do not have permission to edit this page" message was output at the top a number of times, when viewing the page. The bug is not present if the page is rendered by an authenticated user. In going through bug reports it seems this can be triggered by a pretty wide range of problems, most of which are reported as resolved, eg https://bugzilla.wikimedia.org/show_bug.cgi?id=14959 Through very slow delete-save-does-it-work-yet debugging I finally hunted it down to a small typo in a template - {{#arrayap…}} instead of {{#arraymap…}}) - and oddly to assigning a comma separated list to the SMW property. I have no clue why either of these things should cause such behaviour. Anyway, I'm curious if anyone has any experience with the internals behind this bug (or bugs?), and could give me some a starting point to begin digging around and see if I can find a way to ouput a useful error message or something. Also, if anyone has any idea why this only affects anonymous users when anonymous editing is disabled, that might help me find a starting point too, Thanks Andru

dumpBackup.php
by UdoZ 07 Apr '13

07 Apr '13

Hi, I'm using MW 1.20.0 on my own up-to-date Linux server. Everything is working fine except for dumpBackup.php, which I use for Lucene-search. dumpBackup.php does not finish, but stops at random pages and MySql stops working. I have to restart MySql to be able to use the wiki again. Seldomly dumpBackup.php works fine. I can't find any error messages (MySql, Php) and therefore I have no idea what the problem is. Thanks for any help, UdoZ Typicall output, when it stalls: Dumping t4_wiki... 2013-04-07 11:06:21: t4_wiki (ID 28260) 99 pages (1248.5|1248.5/sec all|curr), 100 revs (1261.1|1261.1/sec all|curr), ETA 2013-04-07 11:06:32 [max 13651] [...] 2013-04-07 11:06:22: t4_wiki (ID 28260) 3299 pages (2088.3|78866.7/sec all|curr), 3300 revs (2088.9|2390.6/sec all|curr), ETA 2013-04-07 11:06:27 [max 13651] A database error has occurred.

Special:ActiveUsers End Game?
by Tom Hutchison 06 Apr '13

06 Apr '13

Hi all While looking for a reason our Special:ActiveUsers page and API call was being jailed to current month and not 30 days back(still wondering about it). I was told on irc ActiveUsers had been removed from current MW. Yep, last week a commit to remove the Special page, however it still looks like it is being shown as an active link on the statistics Special page. Got a couple of questions because I don't know if thought out: My first would be - Why? I realize it might give a limited amount of stats, but I find it useful to know who has been active on the wiki rather quickly. Larger wikis or very active wikis should drop the return in days down to keep the db from being hit too hard. e.g. Last 7 days or last 3 days, it can be set in localsettings. Why not a flag to turn off or on the Special page? Seems it would have been simpler to take this route than start axing it out, which now looks like there are some remnants left - the aforementioned Special:Statistics page. There is still a link to the ActiveUsers page, active and errors out on mediawiki.org. Is there a planned alternative? Last year, I think, the API in 1.19 added a way to pull active users with an API call. Will that be removed too? Struggling to get user participation up on a wiki, statistical data helps whether it is huge sets or small sets of data. Every little bit helps. Interested in how everyone else feels about this. Thanks! Tom

2nd level tabs on Media Wiki
by Shrenik Shah 05 Apr '13

05 Apr '13

Hello Everyone, I was wondering if there is a way to create 2 level of tabs in Media Wiki. I followed the steps here: http://www.mediawiki.org/wiki/Extension:Header_Tabs#Usage and have installed the extension. It works perfectly fine with creating single level tabs on top of the page. I wanted to extend this so that I can have tabs within a tabbed page. Is this possible? I would really appreciate any suggestions/comments. p.s This is my first post here so pardon me if I am not posting the right way or not posting the right question. Thank you, Sincerely, Shrenik Shah

Saturated by search engine?
by Jan Steinman 04 Apr '13

04 Apr '13

I periodically experience a DDoS attack from Microsoft. It appears to be their search engines, although I guess a bot network could be messing with reverse DNS. The attacks come from names like "msnbot-nn-nn-nn-nn.search.msn.com", where "nn" are byte values in the IP address. There will be a dozen or more crawling my site at the same time. The symptom is that these guys are so hot and heavy that the number of httpd instances shoots through the roof to the point that none of them get serviced before timing out. I've complained to Microsoft, but of course, received no answer. So why am I complaining here? The logs show that this is only happening to MediaWiki sites I host -- other, simpler sites don't seem to act like a tar pit. I've tried adding ipfilter(8) blocks, but then they just pop up on some other subnet. Also, I don't want to block legit traffic coming from Microsoft. I also don't want to stop spidering via "robots.txt" because I want well-behaved search engines like Google to have access. Anyone else seen this aggressive crawling of their wiki sites? Any ideas for fixing it? Thanks for any advice offered! ---------------- :::: The way you see people is the way you treat them. -- Zig Ziglar :::: Jan Steinman, EcoReality Co-op ::::

How do I police my Media Wiki wiki's ?
by Aaron Gray 02 Apr '13

02 Apr '13

Hi, What extensions are available to police my Media Wiki's ? I have several personal computer language ones which I will want to make public at some point. And more to the point I am wanting to put up a quite high profile one that may/probably get attacked for having political information on it. Many thanks in advance, Aaron

Suggestion: a proper catalog for extensions
by Quim Gil 02 Apr '13

02 Apr '13

Hi, this is a heads up about this suggestion: A proper catalog for extensions https://bugzilla.wikimedia.org/show_bug.cgi?id=46704 We want to know whether this could become a good candidate for the Outreach Program for Women: https://www.mediawiki.org/wiki/Outreach_Program_for_Women Feedback welcome (especially in the bug report). All the better if someone wants to step in as potential mentor for this project. -- Quim Gil Technical Contributor Coordinator @ Wikimedia Foundation http://www.mediawiki.org/wiki/User:Qgil

Fwd: Proposal: Wikitech contributors
by Quim Gil 02 Apr '13

02 Apr '13

fyi -------- Original Message -------- Subject: Proposal: Wikitech contributors Date: Tue, 02 Apr 2013 05:45:58 -0700 From: Quim Gil <qgil(a)wikimedia.org> To: Wikimedia developers <wikitech-l(a)lists.wikimedia.org> I have been drafting a proposal to attract new contributors, help them settle in, and connect them to interesting tasks. It turns out that many of these problems are not unique to new contributors. We suffer them as well and we are just used to them. The proposal has evolved into a deeper restructuring of our community spaces. We're still drafting it, but a round of wider feedback is welcome before opening the official RFC at https://www.mediawiki.org/wiki/Requests_for_comment/Wikitech_contributors In summary: * wikitech.wikimedia.org would become the one and only site for our open source software contributors, powered by semantic software and an ontology of categories shared across wiki pages, Bugzilla and hopefully Gerrit. * Semantic user profiles would identify interests, project membership and preferences so users could get notifications about specific topics. * Nodes would automatically structure links to the key information about a specific topic: wiki pages, events, news, projects, bug reports, Gerrit changesets, related contributors, and people interested. * All project teams, whoever is in them, would have a standard way to report goals, members, tasks and updates. The proposal includes a draft plan for a first iteration, including contracting out some software development and redesigning part of wikitech and mediawiki.org. Your feedback is welcome at the discussion page. I will be consolidating there any feedback received here or through other channels. The official RFC should follow pretty soon, maybe next week. -- Quim Gil Technical Contributor Coordinator @ Wikimedia Foundation http://www.mediawiki.org/wiki/User:Qgil

Re: [MediaWiki-l] Applying for GSoC - Mediawiki
by sandeep kumar 02 Apr '13

02 Apr '13

Hi, I am sandeep and pursuing my MS by Research at IIIT-Hyderabad. I am thinking of applying for GSoC this year. I have gone through the ideas page of mediawiki and find the following ideas quite apt for me to work on. 1. Visual Editor Plugins. 2. Proofread extension needs to be refactored. 3. Prototyping inline comments. I am quick learner and a good programmer. I have good knowledge in *C, C++, Python,Java* etc.. Apart from these, because of my interest in web development i learned *PHP, HTML, MySQL, JavaScript, JQuery* etc.. and implemented several websites for small startups. With the development of websites, i think i gained some experience in UI design as well. Please let me know of further details if i want to work on any of these ideas as part of GSoC. Thank you, Sandeep, MS by Research, IIIT-Hyderabad.
