MediaWiki 1.18 release plans
by Jeroen De Dauw 26 Oct '11

26 Oct '11

Hey, I'm curious to what the release plans for 1.18 are. 1.18wmf1 has been deployed on the wmf wikis, but still there is no beta release for 1.18. For when is such an initial beta planned, and what's the target data for the actual 1.18 release? Cheers -- Jeroen De Dauw http://www.bn2vs.com Don't panic. Don't be evil. --

MediaWiki unit testing and non-MySQL databases
by Brion Vibber 24 Oct '11

24 Oct '11

Hey all -- I've got a stack of issues discussed during the last couple months' conferences and hackathons to raise, so there may be a few more manifestos on the way. But don't worry, this one will be short! I had a great chat at the New Orleans hackathon with D J Bauch who's been working on maintaining MediaWiki's MS SQL Server support, and also had a very useful email chat a couple weeks back with Freakalowsky who's put a lot of work into MediaWiki's Oracle support. Long story short: though traditionally MediaWiki developers have put very little work on our own into maintaining non-MySQL compatibility, there's still lots of folks interested in running on them... AND THEY ACTUALLY MOSTLY WORK! At this point I think it's a bit crazy of us to keep on marginalizing that code; some folks running their own instances will need or want or prefer (or be forced by office IT) to run on some "funny" database, and we shouldn't stand in their way. More importantly, keeping things working with multiple DB backends helps us to keep our code cleaner, and reduces our own hard dependencies on a particular product line. There are two main impediments to keeping code working on non-MySQL platforms: * lazy code breakages -- us MySQL-natives accidentally use MySQL-isms that break queries on other platforms * lazy schema updates -- us MySQL-natives add new schema updates into the system but only implement them for MySQL The first could often be helped simply by having automated testing run to make sure that relevant code paths get exercised. Often there's just a function that's used, or lazy use of LIMIT/OFFSET, or GROUP BY in a form that other databases are pickier about. Just flagging them from the testing can often be enough to make it easy to fix. The second is a bit harder, but again testing can help flag that something needs to be updated so it doesn't wait until too late for the next release, or something. I'd like for everybody who's working on MediaWiki on non-MySQL databases to make sure that the phpunit test suite can run on your favorite platform, so we can see about getting them set up in our regular reports on http://integration.mediawiki.org/ci/ Green bars are your friend! :) -- brion

Re: [Mediawiki-l] MediaWiki-l Digest, Vol 97, Issue 9
by Norman 23 Oct '11

23 Oct '11

Dear Group. Last night, I spoke with my webhosting technical support (iPower.com) and was told that their servers are running php5.2.17, and they have no plans to upgrade to php5.2.9, which is what mediawiki requires. So I presumed that there was not way to make it work on iPower servers and so I uninstalled it. The wiki that is current up is PmWiki, which seems to run perfectly fine but without some features of mediawiki which I like a lot better. I thought about installing legacy version of mediawiki 1.6.5? but the warnings of insecurity scared me out of that. Thanks for looking into it but without the proper modules, I guess having mediawiki hosted at my account is not possible and I just paid for 2yrs too so no chance of moving. :( Norm T. ===================== On Thu, Oct 20, 2011 at 6:12 AM, <mediawiki-l-request(a)lists.wikimedia.org> wrote: > Send MediaWiki-l mailing list submissions to > mediawiki-l(a)lists.wikimedia.org > > To subscribe or unsubscribe via the World Wide Web, visit > https://lists.wikimedia.org/mailman/listinfo/mediawiki-l > or, via email, send a message with subject or body 'help' to > mediawiki-l-request(a)lists.wikimedia.org > > You can reach the person managing the list at > mediawiki-l-owner(a)lists.wikimedia.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of MediaWiki-l digest..." > > > Today's Topics: > > 1.

Adjust article content without modifying page_touched
by Zach H. 22 Oct '11

22 Oct '11

So we are currently using the MediaWiki software to run a Knowledge base system and have a policy that says we will review ALL articles that have not been touched in 365 days to ensure they are still relevant. Coming up with the SQL code to find these was very easy, one feature I was asked to implement was 'is it possible to add a "outdated" tag to a article' so I added the {{outdated}} tag to the wiki, now the hard part is, how do I programmatically update the most current revision without adjusting the page_touched date? is it even possible? I know I can do this via SQL but that is VERY kludgy and I can see all sorts of issues this could cause so I wanted to ask the pro's. Thanks for any assistance in advance. Zach H.

Problem with user page, talk page, other pages, not displaying
by Norman 20 Oct '11

20 Oct '11

Dear Mediawiki support folks; Hello. Please, I need help. I installed and have mediawiki up and running. Problem is that the admin (or user) and My Talk links at the top of the page result in an error message via both IE and FF. So I guess that means there is a problem accessing or creating my pages. This happens whether I am logged in as admin or as another reader/user that I created. I also notice that a few links on the sidebar have the same issue; namely community portal and current events (those links were installed in the default installation). On IE, I get a "page cannot be displayed error" On FF, I get the following error: "Corrupted Content Error The page you are trying to view cannot be shown because an error in the data transmission was detected. The page you are trying to view cannot be shown because an error in the data transmission was detected.Please contact the website owners to inform them of this problem." Can someone help or shed light on this? I really would like to get this operating right and am at a loss, struggling big time. :-( If you would like to see this issue in action, the URL is www.analogalley.com/wiki Thank you in advance, N. Tang.

Upgrading to 1.17
by Eric Armstrong 19 Oct '11

19 Oct '11

The download page for 1.17 has the (somewhat scary) comment: If your MediaWiki installation is heavily modified, it may be difficult to incorporate the latest official changes/updates. (So here's version 1.6.5. It's good for maybe a year.) I accept the need to do whatever integration is necessary-especially since the one-year clock has been ticking for a while now--but I need to know: a) What constitutes "heavy" modification? --We have a installed a number of plugins, have defined some variables, have created several customized skins. Is that heavy or light? b) What, in general, should be the migration process? I'm guessing there are other kinds of modifications that could be done. So ideally the upgrade notes would include a taxonomy of cases: - If you've done "X", you'll need to do "Y". etc. The answers to those questions will help to tell me how much time an upgrade is likely to take. tia! eric ~~~~~~~~~~~~~~~~~~~~ Eric Armstrong Developer Advocate/Evangelist www.longjump.com <http://www.longjump.com/> lj.platformatyourservice.com/wiki LongJump provides a cloud-computing platform that makes it easier to develop & deploy database-driven apps.

PostgreSQL error
by Bret Bailey 19 Oct '11

19 Oct '11

I've installed the mediawiki and ran through the config process, but when I go to http://localhost:8080/mediawiki/index.php, (which is where I installed everything) I get a MediaWiki internal error. I am using PostgreSQL 9.1 on Windows 7, using an apache 2.2.20 server and php v. 5.3.8. The page suggests to run the update.php in the maintenance folder, which produces errors also, but closes before I can read them. Below is what the index.php shows: MediaWiki internal error. Original exception: exception 'DBQueryError' with message 'A database error has occurred. Did you forget to run maintenance/update.php after upgrading? See: http://www.mediawiki.org/wiki/Manual:Upgrading#Run_the_update_script Query: SELECT value,exptime FROM objectcache WHERE keyname = 'my_wiki:messages:en' LIMIT 1 Function: SqlBagOStuff::get Error: 1 ERROR: relation "objectcache" does not exist LINE 1: ...ECT /* SqlBagOStuff::get */ value,exptime FROM objectcach... ^ ' in C:\Program Files (x86)\PostgreSQL\EnterpriseDB-Apache\Php\apache\www\mediawiki\includes\db\Database.php:781 Stack trace: #0 C:\Program Files (x86)\PostgreSQL\EnterpriseDB-Apache\Php\apache\www\mediawiki\includes\db\Database.php(751): DatabaseBase->reportQueryError('ERROR: relatio...', 1, 'SELECT value,e...', 'SqlBagOStuff::g...', false) #1 C:\Program Files (x86)\PostgreSQL\EnterpriseDB-Apache\Php\apache\www\mediawiki\includes\db\Database.php(1050): DatabaseBase->query('SELECT value,e...', 'SqlBagOStuff::g...') #2 C:\Program Files (x86)\PostgreSQL\EnterpriseDB-Apache\Php\apache\www\mediawiki\includes\db\Database.php(1134): DatabaseBase->select('objectcache', Array, Array, 'SqlBagOStuff::g...', Array, Array) #3 C:\Program Files (x86)\PostgreSQL\EnterpriseDB-Apache\Php\apache\www\mediawiki\includes\BagOStuff.php(267): DatabaseBase->selectRow('objectcache', Array, Array, 'SqlBagOStuff::g...') #4 C:\Program Files (x86)\PostgreSQL\EnterpriseDB-Apache\Php\apache\www\mediawiki\includes\MessageCache.php(252): SqlBagOStuff->get('my_wiki:message...') #5 C:\Program Files (x86)\PostgreSQL\EnterpriseDB-Apache\Php\apache\www\mediawiki\includes\MessageCache.php(606): MessageCache->load('en') #6 C:\Program Files (x86)\PostgreSQL\EnterpriseDB-Apache\Php\apache\www\mediawiki\includes\MessageCache.php(545): MessageCache->getMsgFromNamespace('Mainpage', 'en') #7 [internal function]: MessageCache->get('mainpage', true, true) #8 C:\Program Files (x86)\PostgreSQL\EnterpriseDB-Apache\Php\apache\www\mediawiki\includes\StubObject.php(58): call_user_func_array(Array, Array) #9 C:\Program Files (x86)\PostgreSQL\EnterpriseDB-Apache\Php\apache\www\mediawiki\includes\StubObject.php(76): StubObject->_call('get', Array) #10 C:\Program Files (x86)\PostgreSQL\EnterpriseDB-Apache\Php\apache\www\mediawiki\includes\GlobalFunctions.php(781): StubObject->__call('get', Array) #11 C:\Program Files (x86)\PostgreSQL\EnterpriseDB-Apache\Php\apache\www\mediawiki\includes\GlobalFunctions.php(781): StubObject->get('mainpage', true, true) #12 C:\Program Files (x86)\PostgreSQL\EnterpriseDB-Apache\Php\apache\www\mediawiki\includes\GlobalFunctions.php(744): wfMsgGetKey('mainpage', true, true, true) #13 C:\Program Files (x86)\PostgreSQL\EnterpriseDB-Apache\Php\apache\www\mediawiki\includes\GlobalFunctions.php(688): wfMsgReal('mainpage', Array, true, true) #14 C:\Program Files (x86)\PostgreSQL\EnterpriseDB-Apache\Php\apache\www\mediawiki\includes\Title.php(318): wfMsgForContent('mainpage') #15 C:\Program Files (x86)\PostgreSQL\EnterpriseDB-Apache\Php\apache\www\mediawiki\includes\Wiki.php(122): Title::newMainPage() #16 C:\Program Files (x86)\PostgreSQL\EnterpriseDB-Apache\Php\apache\www\mediawiki\index.php(60): MediaWiki->checkInitialQueries(NULL, 'view') #17 {main} How do I get this configured correctly. When I query the objectchache table in the database, I get 2 records, but none have the keyname = 'my_wiki:messages:en' Any help would be greatly appreciated. Thanks.
