* Tests: Remove obsolete jQuery data testsMichał Gołębiowski-Owczarek2020-01-134-115/+0
| | | | | The tests relied on `jQuery.cache` so they only ever worked in jQuery 1.x. Closes gh-4586
* Attributes: Don't set the type attr hook at all outside of IEMichał Gołębiowski-Owczarek2020-01-131-17/+18
| | | | | This removes a needless function call in modern browsers. Closes gh-4587
* Build: Make dev mode work in Karma again, serve source files from diskMichał Gołębiowski-Owczarek2020-01-082-15/+43
| | | | | | | | | | | | | | | | | | PR gh-4550 added support for running ES modules & AMD tests via Karma. This required reading the `esmodules` & `amd` props from both `QUnit.config` & `QUnit.urlParams`. By picking these two properties manually, the `dev` one stopped being respected while ones handled directly by QUnit were fine (like `hidepassed`). Instead of maintaining the full list of options, the code now iterates over QUnit URL config and handles the fallbacks in a more generic way. Apart from that, all jQuery source & test files are now read directly from disk instead of being cached by Karma so that one can run `grunt karma:chrome-debug` & work on a fix without restarting that Karma run after each change. A similar effect could have been achieved by setting `autoWatch` to `true` but then the main Karma page runs tests in an iframe by default when `grunt karma:chrome-debug` is run instead of relying on the current debug flow. Closes gh-4574 Ref gh-4550
* Build:Tests: Fix custom build tests, verify on Travis Michał Gołębiowski-Owczarek2020-01-0726-84/+174
| | | | | | | | | | | This commit fixes unit tests for the following builds: 1. The no-deprecated build: `custom:-deprecated` 2. The current slim build: `custom:-ajax,-effects` 3. The future (#4553) slim build: `custom:-ajax,-callbacks,-deferred,-effects` It also adds separate Travis jobs for the no-deprecated & slim builds. Closes gh-4577
* Docs: Update links to EdgeHTML issues to go through Web ArchiveMichał Gołębiowski-Owczarek2020-01-071-3/+3
| | | | | | With Microsoft going Chromium with Edge, its old EdgeHTML issues were all removed. :( Closes gh-4584
* Build: Create a `grunt custom:slim` alias for the Slim build (#4578)Michał Gołębiowski-Owczarek2020-01-073-2/+25
| | | Closes gh-4578
* Selector: Remove the "a:enabled" workaround for Chrome <=77Michał Gołębiowski-Owczarek2019-12-162-14/+1
| | | | | | | Remove the workaround for a broken `:enabled` pseudo-class on anchor elements in Chrome <=77. These versions of Chrome considers anchor elements with the `href` attribute as matching `:enabled`. Closes gh-4569
* Docs: direct users to GitHub docs for cloning the repoTimmy Willison2019-12-161-6/+2

* Build: Make Karma work in ES modules modeMichał Gołębiowski-Owczarek2019-12-1610-131/+188
| | | | | | Also, run such a suite in CI to make sure modules are working as expected when used directly. Closes gh-4550
* Build: Auto-convert sources to AMDMichał Gołębiowski-Owczarek2019-12-0910-16/+91
| | | | | | | | | | | | | | | jQuery source has been migrated in gh-4541 from AMD to ES modules. To maintain support for consumers of our AMD modules, this commits adds a task transpiling the ES modules sources in `src/` to AMD in `amd/`. A "Load with AMD" checkbox was also restored to the QUnit setup. Note that, contrary to jQuery 3.x, AMD files need to be generated via `grunt amd` or `grunt` as sources are not authored in ECMAScript modules. To achieve a similar no-compile experience during jQuery 4.x testing, use the new "Load as modules" checkbox which works in all supported browsers except for IE & Edge (the legacy, EdgeHTML-based one). Ref gh-4541 Closes gh-4554
* Event: Only attach events to objects that accept data - for realMichał Gołębiowski-Owczarek2019-12-092-2/+12
| | | | | | | | | | There was a check in jQuery.event.add that was supposed to make it a noop for objects that don't accept data like text or comment nodes. The problem was the check was incorrect: it assumed `dataPriv.get( elem )` returns a falsy value for an `elem` that doesn't accept data but that's not the case - we get an empty object then. The check was changed to use `acceptData` directly. Fixes gh-4397 Closes gh-4558
* Docs: Change OS X to macOS in READMEChristian Oliff2019-12-031-1/+1
| | | | | macOS has been around for long enough to update the naming here. Closes gh-4552
* Build: Fix the Windows buildMichał Gołębiowski-Owczarek2019-12-023-18/+51
| | | | | | | This commit gets rid of rollup-plugin-hypothetical in favor of a simpler inline Rollup plugin that fits our need and is compatible with Windows. Fixes gh-4548 Closes gh-4549
* Build: Require extensions for ES6 imports, prevent import cyclesMichał Gołębiowski-Owczarek2019-11-252-0/+8
| | | | | | | | | | | | | | | | jQuery source is now authored in ECMAScript modules. Native browser support for them requires full file names including extensions. Rollup works even if import paths don't specify extensions, though, so one import slipped through without such an extension, breaking native browser import of src/jquery.js. A new ESLint rule using eslint-plugin-import prevents us from regressing on that front. Also, eslint-plugin-import's no-cycle rule is used to avoid import cycles. Closes gh-4544 Ref gh-4541 Ref 075320149ae30a5c593c06b2fb015bdf033e0acf
* Build: Fix the import path to serialize.js from ajax.jsMichał Gołębiowski-Owczarek2019-11-191-1/+1

* Selector: Make empty attribute selectors work in IE againMichał Gołębiowski-Owczarek2019-11-187-9/+39
| | | | | | | | | | qSA in IE 11/Edge often (but not always) don't find elements with an empty name attribute selector (`[name=""]`). Detect that & fall back to Sizzle traversal. Interestingly, IE 10 & older don't seem to have the issue. Fixes gh-4435 Closes gh-4510
* Core: Migrate from AMD to ES modules 🎉Michał Gołębiowski-Owczarek2019-11-18124-1324/+801
| | | | | | | | | | | | | | | | | | | | | | Migrate all source AMD modules to ECMAScript modules. The final bundle is compiled by a custom build process that uses Rollup under the hood. Test files themselves are still loaded via RequireJS as that has to work in IE 11. Tests can now be run in "Load as modules" mode which replaces the previous "Load with AMD" option. That option of running tests doesn't work in IE and Edge as it requires support for dynamic imports. Some of the changes required by the migration: * check `typeof` of `noGlobal` instead of using the variable directly as it's not available when modules are used * change the nonce module to be an object as ECMASscript module exports are immutable * remove some unused exports * import `./core/parseHTML.js` directly in `jquery.js` so that it's not being cut out when the `ajax` module is excluded in a custom compilation Closes gh-4541
* Tests: Skip a "width/height on a table row with phantom borders" test in FirefoxMichał Gołębiowski-Owczarek2019-10-281-1/+8
| | | | | | | | | | | | Firefox 70 & newer fail this test but the issue there is more profound - Firefox doesn't subtract borders from table row computed widths. Closes gh-4537 Ref jquery/jquery#4529 Ref https://bugzilla.mozilla.org/show_bug.cgi?id=1590837 Ref w3c/csswg-drafts#4444 (cherry picked from commit c79e1d5fefc50b1df0a1c2ca3f06b567e79c0f9b)
* Tests: Don't test synchronous XHR on unload in ChromeMichał Gołębiowski-Owczarek2019-10-281-8/+13
| | | | | | | | | | Chrome 78 dropped support for synchronous XHR requests inside of beforeunload, unload, pagehide, and visibilitychange event handlers. See https://bugs.chromium.org/p/chromium/issues/detail?id=952452 Closes gh-4536 (cherry picked from commit c5b48c8caa58e7b73164ac033bf726a072903708)
* Build: Run tests on Travis only on browsers defined in the configMichał Gołębiowski-Owczarek2019-10-221-2/+4
| | | | | | The environmental variable BROWSERS was being created but it wasn't read in the list of browsers to pass to Karma. Closes gh-4532
* Build: Run tests on Firefox ESR as wellMichał Gołębiowski-Owczarek2019-10-221-0/+7

* Build: Run tests on Travis on FirefoxHeadless as wellMichał Gołębiowski-Owczarek2019-10-212-9/+9
| | | | | | | | | | Also, run them on both ChromeHeadless & FirefoxHeadless locally on `grunt karma:main`. Plus, so far, the chrome addons were installed for all the jobs, even the ones that weren't used for browser testing. Changing that makes those jobs faster. Closes gh-4524
* Selector: Use shallow document comparisons in uniqueSortMichał Gołębiowski-Owczarek2019-10-211-3/+16
| | | | | | | | | | | | | | IE/Edge sometimes crash when comparing documents between frames using the strict equality operator (`===` & `!==`). Funnily enough, shallow comparisons (`==` & `!=`) work without crashing. The change to shallow comparisons in `src/selector.js` was done in gh-4471 but relevant changes in `src/selector/uniqueSort.js` were missed. Those changes have landed in Sizzle in jquery/sizzle#459. Fixes gh-4441 Closes gh-4512 Ref gh-4471 Ref jquery/sizzle#459

* Selector: Add a test for throwing on post-comma invalid selectorsMichał Gołębiowski-Owczarek2019-10-211-1/+2
| | | | | | | | | | | | | Sizzle's PR jquery/sizzle#456 introduced a test catching not throwing on badly-escaped identifiers by Firefox 3.6-5. Unfortunately, it was placed just before a test Opera 10-11 failed, making Opera fail quicker and not adding a post-comma invalid selector to rbuggyQSA. The issue was fixed in jquery/sizzle#463. This jQuery commit backports the test that Sizzle PR added as no workarounds are needed in browsers jQuery supports. Closes gh-4516 Ref jquery/sizzle#456 Ref jquery/sizzle#463
* Tests: Stop using jQuery.find in testsMichał Gołębiowski-Owczarek2019-10-212-109/+109
| | | | | This prepares us for possibly hiding jQuery.find in jQuery 4.0. Closes gh-4517
* CSS: Workaround buggy getComputedStyle on table rows in IE/EdgeMichał Gołębiowski-Owczarek2019-10-144-9/+84
| | | | Fixes gh-4490 Closes gh-4506
* Selector: Make selectors with leading combinators use qSA againMichał Gołębiowski-Owczarek2019-10-141-1/+4
| | | | | | | | | | | | | | An optimization added in jquery/sizzle#431 skips the temporary IDs for selectors not using child or descendant combinators. For sibling combinators, though, this pushes a selector with a leading combinator to qSA directly which crashes and falls back to a slower Sizzle route. This commit makes selectors with leading combinators not skip the selector rewriting. Note that after jquery/jquery#4454 & jquery/sizzle#453, all modern browsers other than Edge leverage the :scope pseudo-class, avoiding temporary id attributes. Closes gh-4509 Ref jquery/sizzle#431
* Build: Require strict mode in Node.js scripts via ESLintMichał Gołębiowski-Owczarek2019-10-0911-14/+24
| | | | | | | | So far, only browser-based JS files were required to be in strict mode (in the function form). This commit adds such a requirement to Node.js scripts where the global form is preferred. All Node.js scripts in sloppy mode were converted to strict mode. Closes gh-4499
* Manipulation:Selector: Use the nodeName util where possible to save sizeMichał Gołębiowski-Owczarek2019-10-082-19/+18

* Build: Support jquery-release --dry-run flagMichał Gołębiowski-Owczarek2019-10-051-1/+2
| | | | | | | Without this change passing `--dry-run` to jquery-release still pushes to the jquery-dist repository which is dangerous as one can assume `--dry-run` to be safe from external side effects. Close gh-4498
* Build: Stop copying src/core.js to dist on releaseMichał Gołębiowski-Owczarek2019-10-041-4/+7
| | | | | | | | File `src/core.js` has started erroneously being copied to `dist/` in gh-2981. Fixes gh-4489 Closes gh-4492 Ref gh-2979 Ref gh-2981
* Release: Update AUTHORS.txtMichał Gołębiowski-Owczarek2019-09-262-0/+4
| | | | | | | | | After recent merging of Sizzle & jQuery AUTHORS.txt, the `grunt authors` task doesn't provide meaningful as there's no obvious connection between current AUTHORS.txt contents & the desired one. Adding two new entries should make it easier (plus, it makes it possible to test jquery-release on current master). Apart from that, the commit adds a missing .mailmap entry for Shashanka Nataraj.
* Ajax: Do not execute scripts for unsuccessful HTTP responsesSean Robinson2019-09-264-0/+145
| | | | | | | | | The script transport used to evaluate fetched script sources which is undesirable for unsuccessful HTTP responses. This is different to other data types where such a convention was fine (e.g. in case of JSON). Fixes gh-4250 Closes gh-4379
* Core: Use Array.prototype.flat where supportedAhmed.S.ElAfifi2019-09-255-14/+39
| | | | | | | | | | | Calling `Array.prototype.concat.apply( [], inputArray )` to flatten `inputArray` crashes for large arrays; using `Array.prototype.flat` avoids these issues in browsers that support it. In case it's necessary to support these large arrays even in older browsers, a polyfill for `Array.prototype.flat` can be loaded. This is already being done by many applications. Fixes gh-4320 Closes gh-4459
* Selector: Use shallow document comparisons to avoid IE/Edge crashesMichał Gołębiowski-Owczarek2019-09-251-13/+24

* Selector: reduce size, simplify setDocumentMichał Gołębiowski-Owczarek2019-08-263-130/+128
| | | | | | | | | | | With new selector code doing less convoluted support tests, it was possible to extract a lot of logic out of setDocument & also reduce size. This commit also backports jquery/sizzle#439 that was reverted by mistake during a switch from JSHint + JSCS to ESLint. Closes gh-4462 Ref jquery/sizzle#442 Ref jquery/sizzle#439
* Ajax: Simplify jQuery.ajaxSettings.xhrMichał Gołębiowski-Owczarek2019-08-261-3/+1
| | | | | | | | | | | | | | | Previously, jQuery.ajaxSettings.xhr, contents were wrapped in a try-catch as we defined jQuery.support.ajax & jQuery.support.cors executed during the jQuery load and we didn't want to crash if IE had native XHR disabled (which is possible). While jQuery hasn't supported the ActiveX-based XHR since 2.0, jQuery with XHR disabled could still be used for its other features in such a crippled browser. Since gh-4347, jQuery.support.ajax & jQuery.support.cors no longer exist, so we don't need the try-catch anymore. Fixes gh-1967 Closes gh-4467 Ref gh-4347
* Build: Remove the external directory, read from node_modules directlyMichał Gołębiowski-Owczarek2019-08-2612-41508/+10
| | | | | | Now that Sizzle is gone & we use npm, we can read from node_modules directly and skip the setup that copies some files to the external directory. Closes gh-4466
* Core: Deprecate jQuery.trimShashanka Nataraj2019-08-225-31/+30

* Selector: Leverage the :scope pseudo-class where possibleMichał Gołębiowski-Owczarek2019-08-194-18/+107
| | | | | | | | | | | | | | | | | | | The `:scope` pseudo-class[1] has surprisingly good browser support: Chrome, Firefox & Safari have supported if for a long time; only IE & Edge lack support. This commit leverages this pseudo-class to get rid of the ID hack in most cases. Adding a temporary ID may cause layout thrashing which was reported a few times in [the past. We can't completely eliminate the ID hack in modern browses as sibling selectors require us to change context to the parent and then `:scope` stops applying to what we'd like. But it'd still improve performance in the vast majority of cases. [1] https://developer.mozilla.org/en-US/docs/Web/CSS/:scope Fixes gh-4453 Closes gh-4454 Ref gh-4332 Ref jquery/sizzle#405
* Tests: Fix a comment in testinit.jsMichał Gołębiowski-Owczarek2019-08-191-1/+0
| | | | | | | A copied comment line was accidentally left out above the line defining `QUnit.jQuerySelectorsPos`, making the sentence nonsense. This commit removes that line. Closes gh-4458
