* Switch to librarized version of TestingAccessWrapperGergő Tisza2017-04-201-0/+2
| | | | | | | | | | | | | | | Replaces \TestingAccessWrapper (defined in core) with \Wikimedia\TestingAccessWrapper (defined in the composer package wikimedia/testing-access-wrapper). See https://gerrit.wikimedia.org/r/#/q/topic:librarize-testing-access-wrapper for downstream patches. The core version of the class is kept around for a while to avoid circular dependency problems.

* resourceloader: Consistent stylesheet order for debug and non-debugTimo Tijhof2017-02-171-2/+8
| | | | | | | | | Previously, style modules were only in a predictable order for production mode. In debug mode, the order was determined by order in which modules were added to queue at run time. This made it sometimes hard to debug, especially when dealing with gadgets that apply in a different order among each other. Change-Id: I4bff0c91d127e4ad8015cd8c1775220fe460cbc3
* resourceloader: Remove top/bottom queue distinctionTimo Tijhof2016-11-161-13/+7
| | | | | | | | | | | | | | | | | | | * The styles queue has always been top-only (except for a few months in 2015). * The top queue loads asynchronous since mid-2015. (T107399) And LocalStorage eval, previously the last remaining non-async part of module loading, is also async as of October 2016. (T142129) * This change merges the bottom 'mw.loader.load()' queue with the top queue. It also moves any other snippets potentially in the bottom queue still: - embed: I couldn't find any private modules with position=bottom (doesn't make sense due to their blocking nature). If any do exist, (third-party extensions?), they'll now be embedded in the <head>. - scripts: Any legacy 'only=scripts' requests will now initiate from the <head>.

* resourceloader: Don't cache stale responses in mw.loader.storeTimo Tijhof2016-10-101-3/+12
| | | | | | | | | | | | | | | | Follows-up 6fa1e56. This is already fixed for http caches by shortening the Cache-Control max-age in case of a version mismatch. However the client still cached it blindly in mw.loader.store. Resolve this by communicating to the client what version of the module was exported. The client can then compare this version to the version it originally requested and decide not to cache it. Adopt the module key format (name@version) from mw.loader.store in mw.loader.implement() as well. Bug: T117587 Change-Id: I1a7c44d0222893afefac20bef507bdd1a1a87ecd
* resourceloader: Move queue formatting out of OutputPageTimo Tijhof2016-08-081-0/+278
HTML formatting of the queue was distributed over several OutputPage methods. Each method demanding a snippet of HTML by calling makeResourceLoaderLink() with a limited amount of information. As such, makeResourceLoaderLink() was unable to provide the client with the proper state information. Centralising it also allows it to better reduce duplication in HTML output and maintain a more accurate state. Problems fixed by centralising: 1. The 'user' module is special (due to per-user 'version' and 'user' params). It is manually requested via script-src. To avoid a separate (and wrong) request from something that requires it, we set state=loading directly. However, because the module is in the bottom, the old HTML formatter could only put state=loading in the bottom also. This sometimes caused a wrong request to be fired for modules=user if something in the top queue triggered a requirement for it. 2. Since a464d1d4 (T87871) we track states of page-style modules, with purpose of allowing dependencies on style modules without risking duplicate loading on pages where the styles are loaded already. This didn't work, because the state information about page-style modules is output near the stylesheet, which is after the script tag with mw.loader.load(). That runs first, and mw.loader would still make a duplicate request before it learns the state. Changes: * Document reasons for style/script tag order in getHeadHtml (per 09537e83). * Pass $type from getModuleStyles() to getAllowedModules(). This wasn't needed before since a duplicate check in makeResourceLoaderLink() verified the origin a second time. * Declare explicit position 'top' on 'user.options' and 'user.tokens' module. Previously, OutputPage hardcoded them in the top. The new formatter doesn't. * Remove getHeadScripts(). * Remove getInlineHeadScripts(). * Remove getExternalHeadScripts(). * Remove buildCssLinks(). * Remove getScriptsForBottomQueue(). * Change where Skin::setupSkinUserCss() is called. This methods lets the skin add modules to the queue. Previously it was called from buildCssLinks(), via headElement(), via prepareQuickTemplate(), via OutputPage::output(). It's now in OutputPage::output() directly (slightly earlier). This is needed because prepareQuickTemplate() calls bottomScripts() before headElement(). And bottomScript() would lazy-initialise the queue and lock it before setupSkinUserCss() is called from headElement(). This makes execution order more predictable instead of being dependent on the arbitrary order of data extraction in prepareQuickTemplate (which varies from one skin to another). * Compute isUserModulePreview() and isKnownEmpty() for the 'user' module early on so. This avoids wrongful loading and fixes problem 1. Effective changes in output: * mw.loader.state() is now before mw.loader.load(). This fixes problem 2. * mw.loader.state() now sets 'user.options' and 'user.tokens' to "loading". * mw.loader.state() now sets 'user' (as "loading" or "ready"). Fixes problem 1. * The <script async src> tag for 'startup' changed position (slightly). Previously it was after all inline scripts and stylesheets. It's still after all inline scripts and after most stylesheets, but before any user styles. Since the queue is now formatted outside OutputPage, it can't inject the meta-ResourceLoaderDynamicStyles tag and user-stylesheet hack in the middle of existing output. This shouldn't have any noticable impact. Bug: T87871 Change-Id: I605b8cd1e1fc009b4662a0edbc54d09dd65ee1df
