Cannot access the database after upgrade to MediaWiki 1.31.0

Till Kraemer (talkcontribs)

Hi, I just upgraded to MediaWiki 1.31.0. My repo works fine, however, when I try to load an article on the client wiki, I get the following error:

Sorry! This site is experiencing technical difficulties.

Try waiting a few minutes and reloading.

The local database can be accessed perfectly, special pages like recent changes or user contributions show up properly, but somehow the repo database can't be accessed anymore :/

Any ideas are more than appreciated! Thanks and cheers!

Thiemo Kreuz (WMDE) (talkcontribs)

Did you made sure to run the update.php maintenance script on both the repo and the client database?

Till Kraemer (talkcontribs)

Hi @Thiemo Kreuz (WMDE), thanks for your reply! Yeah, I ran the update script and I just did it again, just to make sure. Same error :/ With older MediaWiki versions I used the Wikidata extension bundle, but it seems to be discontinued. This time, I installed Wikibase using Composer as suggested.

I just noticed that Wikipedia uses WikimediaBadges and WikibaseLexeme, so I wanted to install them too, just in case. Wasn't able to install WikibaseLexeme on the client wiki though. Showed me a blank page.

The LocalSettings.php on the client wiki looks like this:

# Wikibase Extension

$wgEnableWikibaseClient = true;
#$wmgUseWikibaseRepo = false;
#$wmgUseWikibaseClient = true;

# WikimediaBadges Extension
wfLoadExtension( 'WikimediaBadges' );

# WikibaseLexeme Extension
#wfLoadExtension( 'WikibaseLexeme' );

I also noticed that on Wikidata the client is also activated. Did that for my repo too, left $wgEnableWikibaseClient = false; untouched though.

The LocalSettings.php on the repo looks like this:

# WikimediaBadges Extension
wfLoadExtension( 'WikimediaBadges' );

# WikibaseLexeme Extension
wfLoadExtension( 'WikibaseLexeme' );

I don't really know what to do right now :/ Any help is more than welcome. Thanks and cheers!

Thiemo Kreuz (WMDE) (talkcontribs)
  • Please check if the MediaWiki and Wikibase versions you are using match.
  • WikimediaBadges and WikibaseLexeme are optional. If you are not sure, you probably don't need them.
  • The client's configuration format changed. Even if there is backwards-compatibility code in place, it might have failed for you for some reason. What you can try is to add the new format $wgWBClientSettings['repositories'] = …; either in addition or replacing the old $wgWBClientSettings['repoDatabase']. See WikibaseClient.example.php for an example.
Till Kraemer (talkcontribs)

Hi @Thiemo Kreuz (WMDE), thanks for your suggestions!

I just checked the versions again. I'm running MediaWiki 1.31.0 on the clients and on the repo and the Wikibase version file looks like this:

Wikibase: REL1_31

I added $wgWBClientSettings['repositories'] = 'datawiki'; to LocalSettings.php, but when I run the update script, the following error appears:

[abc123567] [no req]   TypeError from line 117 of /path/to/mywikis/en/w/extensions/Wikibase/lib/includes/WikibaseSettings.php: Argument 1 passed to Wikibase\WikibaseSettings::getEntityNamespacesFromRepositorySettings() must be of the type array, string given, called in /path/to/mywikis/en/w/extensions/Wikibase/lib/includes/WikibaseSettings.php on line 111

#9 /path/to/mywikis/en/w/maintenance/update.php(245): require_once(string)
#10 {main}

This also happens when I remove $wgWBClientSettings['repoDatabase'] = 'datawiki';. I'm running PHP 7.0.8. Should I upgrade to 7.0.28?

Thanks and cheers!

Thiemo Kreuz (WMDE) (talkcontribs)

The repositories setting is an array, as shown in the example. The empty array key '' might look confusing. This identifies the default repository, which is what you need. All you need to do is to fill in the values for repoDatabase and baseUri, I believe.

Till Kraemer (talkcontribs)

Hi @Thiemo Kreuz (WMDE), thanks for your help!

For some reason, just adding repoDatabase and baseUri doesn't work for me. If I add this to LocalSettings.php...

$wgWBClientSettings['repositories'] = [
			'repoDatabase' => 'datawiki',
			'baseUri' => 'https://data.mywiki.com/entity',

...I get the following error:

[abc1234567] [no req]   TypeError from line 120 of /path/to/mywikis/en/w/extensions/Wikibase/lib/includes/WikibaseSettings.php: Argument 2 passed to Wikibase\WikibaseSettings::Wikibase\{closure}() must be of the type array, string given

#5 /path/to/mywikis/en/w/extensions/Wikibase/client/includes/Hooks/EchoSetupHookHandlers.php(65): Wikibase\Client\Hooks\EchoSetupHookHandlers::newFromGlobalState()
#6 /path/to/mywikis/en/w/includes/Hooks.php(177): Wikibase\Client\Hooks\EchoSetupHookHandlers::onBeforeCreateEchoEvent(array, array, array)
#7 /path/to/mywikis/en/w/includes/Hooks.php(205): Hooks::callHook(string, array, array, NULL)

#10 /path/to/mywikis/en/w/maintenance/doMaintenance.php(81): require_once(string)
#11 /path/to/mywikis/en/w/maintenance/update.php(245): require_once(string)
#12 {main}

So I added the whole block:

$wgWBClientSettings['repositories'] = [
		'' => [
			'repoDatabase' => 'datawiki',
			'baseUri' => 'https://data.mywiki.com/entity',
			'entityNamespaces' => [
				'item' => WB_REPO_NS_ITEM,
				'property' => WB_REPO_NS_PROPERTY
			'prefixMapping' => [ '' => '' ],

I was now able to run the update script successfully and the item ID links (like https://data.mywiki.com/wiki/Special:EntityPage/Q1234567) show up on the client wiki. However, the interwiki links don't appear on the client wiki and I have the following error in my log file:

Not sure what I'm missing here :/

Thanks and cheers!

Thiemo Kreuz (WMDE) (talkcontribs)

Oh, I have never seen this message before. It sounds like a secondary database table got out of sync. I'm afraid I need to hand over to the core Wikidata team. Maybe Leszek can help?

PS: I just realized your item namespace is NS_MAIN, not WB_REPO_NS_ITEM. You need to fix this in the configuration you just added.

Till Kraemer (talkcontribs)

Hi @Thiemo Kreuz (WMDE), I changed WB_REPO_NS_ITEM to NS_MAIN in LocalSettings.php as you suggested and woohoo, it works perfectly now! :) Thank you so much for your help! I'm soo happy now! :) Long live Wikibase and Thiemo Kreuz! :)

I wonder I can run mediaWiki 1.32 without database replication?

Alex Lai

Thiemo Kreuz (WMDE) (talkcontribs)

Hey Alex. Is this question related to Wikibase? If not, I'm afraid this is the wrong page to ask. I'm also not sure if we are talking about the same when we say "database replication". What is the exact issue you run into?

Wikibase Client installation

8 (talkcontribs)

I installed wikibase lib and client Configured as follows $wgWBSettings['repoUrl'] = '//www.wikidata.org'; $wgWBSettings['repoScriptPath'] = '/mediawiki'; $wgWBSettings['repoArticlePath'] = '/mediawiki/$1'; $wgWBSettings['siteGlobalID'] = 'mywiki'; $wgWBSettings['repoDatabase'] = 'mwikidb'; $wgWBSettings['changesDatabase'] = 'mywikidb';

I tried to get a property from repoUrl with: {{#property:q260}} but nothing happen .

Some hints how to configure or use wikidata in mywiki ?

Regards g

Katie Filbert (WMDE) (talkcontribs)

Do you have Wikibase Repo enabled somewhere? Wikibase Client cannot access wikidata.org, except for within wikimedia servers where the wikidata clients (e.g. wikipedia) are able to access the wikidata database directly. If you have your own Wikibase Repo instance, then update repoUrl and double check the repoDatabase setting (e.g. do you really intend it to be different from changesDatabase?). Cheers. (talkcontribs)

I was thinking it should be possible to have the client only as reader, to access the wikidata data. FYI: I defined my own Wikibase Repo and it was working, but this was not the original goal,

Thanks g

Lydia Pintscher (WMDE) (talkcontribs)

A third-party client like you want to do it is not possible yet.

Jeroen De Dauw (talkcontribs)

It should not be far off... Maybe we ought to provide a list of things not working yet. This is all I can think off, and those are just guesses as I'm not up to speed with client state:

  • No change propagation system usable by non-WMF available yet, would need custom coding/setup from third party side at present
  • Not able to write back to repo due to cross domain request policies messing with API requests (this one I'm really not sure about)

Anything else?

Emijrp (talkcontribs)

Is it possible now? Or not yet? I would like to access to Wikidata data from an external wiki. Is there any workaround? Thanks.

Lydia Pintscher (WMDE) (talkcontribs)

It's not possible yet and to be honest there are a ton of more important things we need to do before we get to this  :/

Tosfos (talkcontribs)

It's been a while. Is this possible yet?

Paucabot (talkcontribs)

Can someone explain me why the title of a wiki page is not automatically used for the label of the item when a wikipedia page is added in that language from the wikipedia? It is this way by default if you create an item, but not if you only add a link to a wikipedia page. Why is that behaviour of this Wikibase Client?

Thanks in advance.

Extension not working on tr.wiktionary

HastaLaVi2 (talkcontribs)

On this module, there is a line "local URL = mw.wikibase.getEntityUrl(wikidataItem)", but it won't work the way it should like its english wiktionary version. When I remove "mw.wikibase" from if condition it says "wikibase is a nil value", why is that?

Lydia Pintscher (WMDE) (talkcontribs)

All Wiktionaries except English don't yet have arbitrary access enabled. You can file a ticket on phabricator.wikimedia.org to get it enabled.

Need help with installing to Mediawiki 1.31

Zzmonty (talkcontribs)

Can somebody please post what exactly you put into your LocalSettings.php for a client only install of this extension to access wikidata.org? Thanks.

Thiemo Kreuz (WMDE) (talkcontribs)
Zzmonty (talkcontribs)

Tried that and nothing works. I also looked at the advanced installation, and tried to copy those items and it did not work. If you got this to work with a 1.31 mediawiki, and the client only part of this extension, if you could just look at your LocalSettings.php file and just copy everything that you have in that file related to this extension it would be much appreciated. Maybe another extension I have installed is conflicting with this extension. i don't know. I just know that i followed the instructions a couple of times, and I could not get this extension to even load.

The only other item is that I don't have composure, so I was trying to manually install the extension. Did I miss some dependency either with a third party application or else another extension?

Thiemo Kreuz (WMDE) (talkcontribs)

Please describe what "did not work" means. What error message do you get on which page in which namespace?

Having the libraries Wikibase depends on installed via Composer is a must. I'm not aware of a way to do this "manually".

Zzmonty (talkcontribs)

Then that is where the problem is, because I did not use composer.

At this point Wikibase requires more up-to-date code than MediaWiki 1.28.2. Have you tried installing the latest code from git?

I have now tried ver. 1.29.0 and 1.30.0-alpha (from Git) with the same result.

Summary by Thiemo Kreuz (WMDE)
Cwek (talkcontribs)

I put this into the article on zh.wp. And I found that it outputs a incomplete code-block of Language Converter.

like w:zh:新浪微博 , it outputed that 'http://www.weibo.com">http://www.weibo.com;zh-hans:http://www.weibo.com;zh-hant:http://www.weibo.com;zh-cn:http://www.weibo.com;zh-hk:http://www.weibo.com;zh-mo:http://www.weibo.com;zh-sg:http://www.weibo.com;zh-tw:http://www.weibo.com;}-'

But I use Special:ExpandTemplates to parse it, it's output is clean, just 'http://www.weibo.com'.

meta:Tech/News/2016/41has a news about 'Language converter syntax will soon no longer work inside external links.' , Is it about this problem? And I can't find the function of {{#property:}} in the source code of Wikibase, so I want to know whether it have a i18n Mediawiki-namespace page to control it ,or a hard code to format the output of URL with Language Converter?

Tacsipacsi (talkcontribs)

I suggest you to report it on Phabricator, the bug tracker of Wikimedia, as I’m not sure if any developer is watching this page, and there you can tag both Wikidata and Language Converter so that developers of both products will notice it. Wikidata bugs can be reported here (you can easily create a Phabricator account with your existing Wikimedia account).

Cwek (talkcontribs)

Thanks, I will.

ערן (talkcontribs)

@Tobias Gritschacher (WMDE) , thank you for improving the documentation and moving advanced details into their own page. However, I think the last changes in this page is hiding important basic information that should appear here. For example: how to use #property is now located in Wikibase/Installation/Advanced configuration. Also, the last changes break the " parser functions" link in the intro. Can you please fix it? Thanks

Error installing Extension:Wikibase

Benet tallaferro (talkcontribs)

Hi Everybody,

in advance, thankyou for reading me.

I want to install the extension: wikibase, since I need it in order to use Template:Infobox person .

I copy the extension folder into wiki/extension/ folder, and I copy the following lines to the LocalSettings.php file, as it is recommended in the installation guide.

$wgEnableWikibaseRepo = false;

$wgEnableWikibaseClient = true;

require_once "$IP/extensions/Wikibase/client/WikibaseClient.php";

require_once "$IP/extensions/Wikibase/client/ExampleSettings.php";

And still I am getting the error message: Sorry, we have problems. Cannot acces the database.

What can I do?

Thankyou for your attention,


TMg (talkcontribs)

What exactly do you want to achieve? I assume you copied the code of en:Template:Infobox person to a local MediaWiki installation you own? Is this correct? Do you want to use data from wikidata.org in this template, or from your own Wikibase Repo? Note that the Wikibase Client software currently needs direct database access to the Repo. Both must run on the same server because of this.

Tacsipacsi (talkcontribs)

If you have database problems, it probably means that you haven’t run update.php.

Javascript: wikibase is not defined

Samwilson (talkcontribs)

After enabling the Wikibase client, I was hoping to be able to use the <code>wikibase.client</code> javascript resources, but it seems they're not being loaded: <code>wikibase is not defined</code>

Can anyone tell me where I've gone wrong? I've tried to follow all the installation instructions.

Tacsipacsi (talkcontribs)

Have you used mw.loader.using('wikibase.client.X', ...)? Otherwise it will be loaded only if used by another module.
