User talk:SPQRobin/Page language

1. I had a question- why is using page_props a bad idea? Will it break a lot of things? --User:Kunalgrover05 (talk)
 * I understood it as this based on discussion with Brian Wolff. Page_props depends on the page to be existent first. It is better to create a field in the page table as it is a property of the page itself Kunalgrover05 (talk) 11:34, 22 May 2014 (UTC)

User interface
I suggest to avoid having to deal with any user interface consideration at first. It's fine, for instance, to create a separate special page Special:PageLanguage which does only that and is not linked from anywhere (except Special:SpecialPages of course). Further integration and refinement of UI can come later. --Nemo 15:32, 22 May 2014 (UTC)

Suggestions from Nikerabbit

 * Default language should be current default
 * Hooks should be able to override user selection
 * Language should be stored in the database
 * Should be available via relevant APIs --Kunalgrover05 (talk) 17:25, 22 May 2014 (UTC)

Discussion with Brian Wolff

 * In order to not require to update all the databases, don't need to set the page language in database(keep it null) until it is different from the default wiki language.
 * Have a SpecialPage until the interface is finalized.
 * Using a hook for extensions to override the DB choice Kunalgrover05 (talk) 05:39, 26 May 2014 (UTC)

Review by Anomie

 * Need to take care of the ContentHandler:getPageLanguage method as well.
 * Need to have a way to get page language for MW namespace.
 * Extensions might be setting the PageLanguage using the hook.

Suggestion from SPQRobin

 * Have the Title->getPageLanguage as a central function that should call ContentHandler, the DB and the hook and return the correct language.

Front end suggestions from Liangent
Using ?action=info to set the page language.

Suggestion from Mark Traceur
Need to add logging for Page Language

Suggestions from Siebrand

 * Need to have performance engineering approval
 * This code should not break when the schema update is not yet applied. Need to find a fix for that.

Is Special:PageLanguage fully working with extension translate (MW 1.24.2, MLEB 2015.04)?
Just to announce see Extension_talk:Translate --Andreas P. 22:08, 22 May 2015 (UTC)
