I guess the expectation was that for browsers that don't support Navigator.sendBeacon, the promise would wait for the 'new Image' fallback to complete. However, EventLogging never did that. In browsers where the Beacon API is not supported, 'new Image' starts asynchronously and either way the returned promise is immediately resolved. The only purpose of the returned promise was to detect errors in the format of the event (e.g. missing properties), which this code is not concerned with (given that it uses "always", not "done"). And besides, for that you'd probably want to use the EventLogging debug mode [1] instead. This is the last step before ULS can switch to a soft EL dependency by using mw.track instead, which I'll do in the next commit. Change-Id: If016b73dcd7320ddf1478c1678d2cc6371fe0fa1
== Universal Language Selector == The Universal Language Selector extension (ULS) provides a flexible way to configure and deliver language settings like interface language, fonts, and input methods (keyboard mappings). This will allow users to type text in different languages not directly supported by their keyboard, read content in a script for which fonts are not available locally, or customise the language in which menus are displayed. For more information see: https://www.mediawiki.org/wiki/Universal_Language_Selector == Copying == You may use any Project Milkshake product, including the Universal Language Selector, under the terms of either the MIT License or the GNU General Public License (GPL) Version 2 or later. See GPL-LICENSE and MIT-LICENSE for details. == Installation == For a very, very quick start add the following lines to LocalSettings.php of your MediaWiki setup: wfLoadExtension( 'UniversalLanguageSelector' ); By default, ULS will appear at personal toolbar position. If you want ULS at interlanguage position, add the following line: $wgULSPosition = 'interlanguage'; == For Developers == The MediaWiki Universal Language Selector project uses jquery.uls: https://github.com/wikimedia/jquery.uls Its development is at Wikimedia Github account. Any fixes to lib/ should happen at Github. Follow the build instructions of jquery.uls to create jquery.uls.js. Bugs for the extension are handled in Phabricator: https://phabricator.wikimedia.org/tag/mediawiki-extensions-universallanguageselector/
