resourceloader: Enable module content version for data modules This greatly simplifies logic required to compute module versions. It also makes it significantly less error-prone. Since f37cee996e, we support hashes as versions (instead of timestamps). This means we can build a hash of the content directly, instead of compiling a large array with all values that may influence the module content somehow. Benefits: * Remove all methods and logic related to querying database and disk for timestamps, revision numbers, definition summaries, cache epochs, and more. * No longer needlessly invalidate cache as a result of no-op changes to implementation datails. Due to inclusion of absolute file paths in the definition summary, cache was always invalidated when moving wikis to newer MediaWiki branches; even if the module observed no actual changes. * When changes are reverted within a certain period of time, old caches can now be re-used. The module would produce the same version hash as before. Previously when a change was deployed and then reverted, all web clients (even those that never saw the bad version) would have re-fetch modules because the version increased. Updated unit tests to account for the change in version. New default version of empty test modules is: "mvgTPvXh". For the record, this comes from the base64 encoding of the SHA1 digest of the JSON serialised form of the module content: > $str = '{"scripts":"","styles":{"css":[]},"messagesBlob":"{}"}'; > echo base64_encode(sha1($str, true)); > FEb3+VuiUm/fOMfod1bjw/te+AQ= Enabled content versioning for the data modules in MediaWiki core: * EditToolbarModule * JqueryMsgModule * LanguageDataModule * LanguageNamesModule * SpecialCharacterDataModule * UserCSSPrefsModule * UserDefaultsModule * UserOptionsModule The FileModule and base class explicitly disable it for now and keep their current behaviour of using the definition summary. We may remove it later, but that requires more performance testing first. Explicitly disable it in the WikiModule class to avoid breakage when the default changes. Ref T98087.

resourceloader: Add context param to ResourceLoaderModule::getDependencies By providing context as a parameter in getDependencies, we allow modules to dyanamically determine dependencies based on context. Note: To ease rollout, the parameter is optional in this patch. It is expected that it will be made non-optional in the near future. The use case is for CentralNotice campaigns to be able to add special modules ahead of deciding which banner to show a user. The dynamically chosen RL modules would replace ad-hoc JS currently sent with some banners. A list of possible campaigns and banners is already sent as a PHP- implemented RL module; that's the module that will dynamically choose other modules as dependencies when appropriate. This approach will save a round trip as compared to dynamically loading the modules client-side. For compatibility, extensions that override ResourceLoaderModule::getDependencies() should be updated with the new method signature. Here are changes for extensions currently deployed on Wikimedia wikis: * CentralNotice: I816bffa3815e2eab7e88cb04d1b345070e6aa15f * Gadgets: I0a10fb0cbf17d095ece493e744296caf13dcee02 * EventLogging: I67e957f74d6ca48cfb9a41fb5144bcc78f885e50 * PageTriage: Ica3ba32aa2fc76d11a44f391b6edfc871e7fbe0d * UniversalLanguageSelector: Ic63e617f51702c27104e123d4bed91983a726b7f * VisualEditor: I0ac775ca286e64825e31a9213b94648e41a5bc30 For more on the CentralNotice use case, please see I9f80edcbcacca2.
