* Tests: Add custom attribute getter tests to the selector moduleMichał Gołębiowski-Owczarek2024-12-161-0/+31
| | | | | | | | | | | | Sizzle & the `3.x-stable` branch have tests adding a custom attribute getter to `attrHandle` and checking if selection takes it into account. `attrHandle` was removed from the `4.x` line so the tests were not ported to the `main` branch, but the `4.x` line takes standard jQuery attribute getters into account instead and we should test for that. Backport the `3.x-stable` selector tests for custom attribute getters, changing `jQuery.expr.attrHandle` to `jQuery.attrHooks`. Closes gh-5568
* CSS: Drop the cache in finalPropNameMichał Gołębiowski-Owczarek2024-11-261-10/+24
| | | | | | | | | | | The `finalPropName` util caches properties detected to require a vendor prefix. This used to cache unprefixed properties as well, but it was reported that this logic broke accidentally during a refactor. Since fewer & fewer properties require a vendor prefix and caching a few basic checks likely has negligible perf benefits, opt to saving a few bytes and remove the cache. Closes gh-5583 Ref gh-5582
* Selector: Properly deprecate `jQuery.expr[ ":" ]`/`jQuery.expr.filters`Michał Gołębiowski-Owczarek2024-11-042-8/+21
| | | | | | | | | | | Those APIs have formally been deprecated since `3.0.0`, but they never made its way into the deprecated module. `jQuery.expr[ ":" ]` has been removed when Sizzle got inlined into Core in gh-4395; this change restores it. Closes gh-5580 Ref gh-5570 Ref gh-4395
* Manipulation: Make jQuery.cleanData not skip elements during cleanupac-mmi2024-09-111-0/+40
| | | | | | | | | | | | When passing a result of `getElementByTagsName` to `jQuery.cleanData`, convert it to an array first. Otherwise, a live NodeList is passed and if any of the event cleanups remove the element itself, a collection is modified during the iteration, making `jQuery.cleanData` skip cleanup for some elements.

* CSS:Tests: Fix tests & support tests under CSS ZoomMichał Gołębiowski-Owczarek2024-06-032-2/+16
| | | | | | | | | | | | Firefox 126+ implements CSS zoom in a way it affects width computed style very slightly (`100.008px` instead of `100px`); accept that difference. Add a test for support tests resolving the same under CSS zoom & without one. That test uncovered Chrome failing the `reliableTrDimensions` support test under zoom; the test has been fixed.

* Event: Increase robustness of an inner native event in leverageNativeMichał Gołębiowski-Owczarek2024-05-201-0/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | In Firefox, alert displayed just before blurring an element dispatches the native blur event twice which tripped the jQuery logic if a jQuery blur handler was not attached before the trigger call. This was because the `leverageNative` logic part for triggering first checked if setup was done before (which, for example, is done if a jQuery handler was registered before for this element+event pair) and - if it was not - added a dummy handler that just returned `true`. The `leverageNative` logic made that `true` then saved into private data, replacing the previous `saved` array. Since `true` passed the truthy check, the second native inner handler treated `true` as an array, crashing on the `slice` call. The same issue could happen if a handler returning `true` is attached before triggering. A bare `length` check would not be enough as the user handler may return an array-like as well. To remove this potential data shape clash, capture the inner result in an object with a `value` property instead of saving it directly. Since it's impossible to call `alert()` in unit tests, simulate the issue by replacing the `addEventListener` method on a test button with a version that calls attached blur handlers twice. Fixes gh-5459 Closes gh-5466 Ref gh-5236
* Tests: Make the beforeunload event tests work regardless of extensionsMichał Gołębiowski-Owczarek2024-04-251-5/+14
| | | | | | | | | | | Some browser extensions, like React DevTools, send messages to the content area. Since our beforeunload event test listens for all messages, it used to catch those as well, failing the test. Add a `source` field to the payload JSON and check for it before treating the message as coming from our own test to make sure the test passes even with such browser extensions installed. Closes gh-5478

* Attributes: Make `.attr( name, false )` remove for all non-ARIA attrsMichał Gołębiowski-Owczarek2024-03-202-18/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The HTML spec defines boolean attributes: https://html.spec.whatwg.org/#boolean-attributes that often correlate with boolean properties. If the attribute is missing, it correlates with the `false` property value, if it's present - the `true` property value. The only valid values are an empty string or the attribute name. jQuery tried to be helpful here and treated boolean attributes in a special way in the `.attr()` API: 1. For the getter, as long as the attribute was present, it was returning the attribute name lowercased, ignoring the value. 2. For the setter, it was removing the attribute when `false` was passed; otherwise, it was ignoring the passed value and set the attribute - interestingly, in jQuery `>=3` not lowercased anymore. The problem is the spec occasionally converts boolean attributes into ones with additional attribute values with special behavior - one such example is the new `"until-found"` value for the `hidden` attribute. Our setter normalization means passing those values is impossible with jQuery. Also, new boolean attributes are introduced occasionally and jQuery cannot easily add them to the list without incurring breaking changes. This patch removes any special handling of boolean attributes - the getter returns the value as-is and the setter sets the provided value. To provide better backwards compatibility with the very frequent `false` value provided to remove the attribute, this patch makes `false` trigger attribute removal for ALL non-ARIA attributes. ARIA attributes are exempt from the rule since many of them recognize `"false"` as a valid value with semantics different than the attribute missing. To remove an ARIA attribute, use `.removeAttr()` or pass `null` as the value to `.attr()` which doesn't have this exception.

* Tests: migrate testing infrastructure to minimal dependenciesTimmy Willison2024-02-266-94/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a complete rework of our testing infrastructure. The main goal is to modernize and drop deprecated or undermaintained dependencies (specifically, grunt, karma, and testswarm). We've achieved that by limiting our dependency list to ones that are unlikely to drop support any time soon. The new dependency list includes: - `qunit` (our trusty unit testing library) - `selenium-webdriver` (for spinning up local browsers) - `express` (for starting a test server and adding middleware) - express middleware includes uses of `body-parser` and `raw-body` - `yargs` (for constructing a CLI with pretty help text) - BrowserStack (for running each of our QUnit modules separately in all of our supported browsers) - `browserstack-local` (for opening a local tunnel. This is the same package still currently used in the new Browserstack SDK) - We are not using any other BrowserStack library. The newest BrowserStack SDK does not fit our needs (and isn't open source). Existing libraries, such as `node-browserstack` or `browserstack-runner`, either do not quite fit our needs, are under-maintained and out-of-date, or are not robust enough to meet all of our requirements. We instead call the [BrowserStack REST API](https://github.com/browserstack/api) directly. ## BrowserStack Runner - automatically retries individual modules in case of test failure(s) - automatically attempts to re-establish broken tunnels - automatically refreshes the page in case a test run has stalled - runs all browsers concurrently and uses as many sessions as are available under the BrowserStack plan. It will wait for available sessions if there are none. - supports filtering the available list of browsers by browser name, browser version, device, OS, and OS version (see `npm run test:unit -- --list-browsers` for more info). It will retrieve the latest matching browser available if any of those parameters are not specified. - cleans up after itself (closes the local tunnel, stops the test server, etc.) - Requires `BROWSERSTACK_USERNAME` and `BROWSERSTACK_ACCESS_KEY` environment variables. ## Selenium Runner - supports running any local browser as long as the driver is installed, including support for headless mode in Chrome, FF, and Edge - supports running `basic` tests on the latest [jsdom](https://github.com/jsdom/jsdom#readme), which can be seen in action in this PR (see `test:browserless`) - Node tests will run as before in PRs and all non-dependabot branches, but now includes tests on real Safari in a GH actions macos image instead of playwright-webkit. - can run multiple browsers and multiple modules concurrently Other notes: - Stale dependencies have been removed and all remaining dependencies have been upgraded with a few exceptions: - `sinon`: stopped supporting IE in version 10. But, `sinon` has been updated to 9.x. - `husky`: latest does not support Node 10 and runs on `npm install`. Needed for now until git builds are migrated to GitHub Actions. - `rollup`: latest does not support Node 10. Needed for now until git builds are migrated to GitHub Actions. - BrowserStack tests are set to run on each `main` branch commit - `debug` mode leaves Selenium browsers open whether they pass or fail and leaves browsers with test failures open on BrowserStack. The latter is to avoid leaving open too many sessions. - This PR includes a workflow to dispatch BrowserStack runs on-demand - The Node version used for most workflow tests has been upgraded to 20.x - updated supportjQuery to 3.7.1 Run `npm run test:unit -- --help` for CLI documentation Close gh-5418

| | | | | | | | | | | | | | | | | | | Bootstrap 5 includes the following CSS on the page: ```css *, *::before, *::after { box-sizing: border-box; } ``` That threw our `reliableTrDimensions` support test off.

* Selector: Re-expose jQuery.find.{tokenize,select,compile,setDocument}Michał Gołębiowski-Owczarek2023-06-121-0/+229
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | `Sizzle.tokenize` is an internal Sizzle API, but exposed. As a result, it has historically been available in jQuery via `jQuery.find.tokenize`. That got dropped during Sizzle removal; this change restores the API. Some other APIs so far only exposed on the `3.x` line are also added back: * `jQuery.find.select` * `jQuery.find.compile` * `jQuery.find.setDocument` In addition to that, Sizzle tests have been backported for the following APIs: * `jQuery.find.matchesSelector` * `jQuery.find.matches` * `jQuery.find.compile` * `jQuery.find.select` A new test was also added for `jQuery.find.tokenize` - even Sizzle was missing one.

* Tests: Indicate Chrome 112 & Safari 16.4 pass the cssHas support testMichał Gołębiowski-Owczarek2023-04-051-13/+25
| | | | | | | | | | | Chrome 112 & Safari 16.4 introduce two changes: * `:has()` is non-forgiving * `CSS.supports( "selector(...)" )` parses everything in a non-forgiving way We no longer care about the latter but the former means the `cssHas` support test now passes. Closes gh-5225
* CSS: Make `offsetHeight( true )`, etc. include negative marginsMichał Gołębiowski-Owczarek2023-04-041-1/+6
| | | | | | | | | | | | This regressed in gh-3656 as the added logic to include scroll gutters in `.innerWidth()` / `.innerHeight()` didn't take negative margins into account. This broke handling of negative margins in `.offsetHeight( true )` and `.offsetWidth( true )`. To fix it, calculate margin delta separately and only add it after the scroll gutter adjustment logic. Fixes gh-3982 Closes gh-5234 Ref gh-3656
* Event: Avoid collisions between jQuery.event.special & Object.prototypeMichał Gołębiowski-Owczarek2023-04-031-0/+20

* Event: Make trigger(focus/blur/click) work with native handlersMichał Gołębiowski-Owczarek2023-03-271-2/+61
| | | | | | | | | | | | | | | | | | In `leverageNative`, instead of calling `event.stopImmediatePropagation()` which would abort both native & jQuery handlers, set the wrapper's `isImmediatePropagationStopped` property to a function returning `true`. Since for each element + type pair jQuery attaches only one native handler, there is also only one wrapper jQuery event so this achieves the goal: on the target element jQuery handlers don't fire but native ones do. Unfortunately, this workaround doesn't work for handlers on ancestors - since the native event is re-wrapped by a jQuery one on each level of the propagation, the only way to stop it for jQuery was to stop it for everyone via native `stopPropagation()`. This is not a problem for `focus`/`blur` which don't bubble, but it does also stop `click` on checkboxes and radios. We accept this limitation. Fixes gh-5015 Closes gh-5228
* Event: Simulate focus/blur in IE via focusin/focusoutMichał Gołębiowski-Owczarek2023-03-271-120/+202
| | | | | | | | | | | | | | | | | | | | | | | | In IE (all versions), `focus` & `blur` handlers are fired asynchronously but `focusin` & `focusout` are run synchronously. In other browsers, all those handlers are fired synchronously. Asynchronous behavior of these handlers in IE caused issues for IE (gh-4856, gh-4859). We now simulate `focus` via `focusin` & `blur` via `focusout` in IE to avoid these issues. This also let us simplify some tests. This commit also simplifies `leverageNative` - with IE now using `focusin` to simulate `focus` and `focusout` to simulate `blur`, we don't have to deal with async events in `leverageNative`. This also fixes broken `focus` triggers after first triggering it on a hidden element - previously, `leverageNative` assumed that the native `focus` handler not firing after calling the native `focus` method meant it would be handled later, asynchronously, which was not the case (gh-4950).

* Ajax: Don't treat array data as binaryMichał Gołębiowski-Owczarek2023-03-211-67/+201
| | | | | | | | | | | | | PR gh-5197 started treating all non-string non-plain-object `data` values as binary. However, `jQuery.ajax` also supports arrays as values of `data`. This change makes regular arrays no longer be considered binary data. Surprisingly, we had no tests for array `data` values; otherwise, we'd detect the issue earlier. This change also adds a few such missing tests. Closes gh-5203 Ref gh-5197
* Ajax: Allow `processData: true` even for binary dataMichał Gołębiowski-Owczarek2023-03-201-0/+23
| | | | | | | | | | The way gh-5197 implemented binary data handling, `processData` was being explicitly set to `false`. This is expected but it made it impossible to override it to `true`. The new logic will only set `processData` to `false` if it wasn't explicitly passed in original options. Closes gh-5205 Ref gh-5197
* Tests: Test AJAX deprecated event aliases properlyMichał Gołębiowski-Owczarek2023-03-151-5/+5

* Deferred: Rename `getStackHook` to `getErrorHook`Michał Gołębiowski-Owczarek2023-03-141-6/+6
| | | | | | | | | | | | | | Rename `jQuery.Deferred.getStackHook` to `jQuery.Deferred.getErrorHook` to indicate passing an error instance is usually a better choice - it works with source maps while a raw stack generally does not. In jQuery `3.7.0`, we'll keep both names, marking the old one as deprecated. In jQuery `4.0.0` we'll just keep the new one. This change implements the `4.0.0` version; PR gh-5212 implements the `3.7.0` one. Fixes gh-5201 Closes gh-5211 Ref gh-5212
* Selector: Stop relying on CSS.supports( "selector(...)" )Michał Gołębiowski-Owczarek2023-02-141-8/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | `CSS.supports( "selector(...)" )` has different semantics than selectors passed to `querySelectorAll`. Apart from the fact that the former returns `false` for unrecognized selectors and the latter throws, `qSA` is more forgiving and accepts some invalid selectors, auto-correcting them where needed - for example, mismatched brackers are auto-closed. This behavior difference is breaking for many users. To add to that, a recent CSSWG resolution made `:is()` & `:where()` the only pseudos with forgiving parsing; browsers are in the process of making `:has()` parsing unforgiving. Taking all that into account, we go back to our previous try-catch approach without relying on `CSS.supports( "selector(...)" )`. The only difference is we detect forgiving parsing in `:has()` and mark the selector as buggy. The PR also updates `playwright-webkit` so that we test against a version of WebKit that already has non-forgiving `:has()`.

* Selector: Backport jQuery selection context logic to selector-nativeMichał Gołębiowski-Owczarek2023-02-133-79/+51
| | | | | | | | | | | | | | | | | | | | | | This makes: ```js $div.find("div > *") ``` no longer matching children of `$div`. Also, leading combinators now work, e.g.: ```js $div.find( "> *" ); ``` returns children of `$div`. As a result of that, a number of tests are no longer skipped in the `selector-native` mode. Also, rename `rcombinators` to `rleadingCombinator`. Fixes gh-5185 Closes gh-5186 Ref gh-5085
* Ajax: Support binary data (including FormData)Michał Gołębiowski-Owczarek2023-02-011-0/+43
| | | | | | | | | | | | Two changes have been applied: * prefilters are now applied before data is converted to a string; this allows prefilters to disable such a conversion * a prefilter for binary data is added; it disables data conversion for non-string non-plain-object `data`; for `FormData` bodies, it removes manually-set `Content-Type` header - this is required as browsers need to append their own boundary to the header Ref gh-4150 Closes gh-5197
* Deferred: Respect source maps in jQuery.Deferred.exceptionHookMichał Gołębiowski-Owczarek2023-02-011-3/+3
| | | | | | | | | | | | | | | | | | So far, `jQuery.Deferred.exceptionHook` used to log error message and stack separately. However, that breaks browser applying source maps against the stack trace - most browsers require logging an error instance. This change makes us do exactly that. One drawback of the change is that in IE 11 previously stack was printed directly and now just the error summary; to get to the actual stack trace, three clicks are required. This seems to be a low price to pay for having source maps work in all the other browsers, though. Safari with the new change requires one click to get to the stack trace which sounds manageable. Fixes gh-3179 Closes gh-5192 Ref https://crbug.com/622227
* Ajax: Support `headers` for script transport even when cross-domainMichał Gołębiowski-Owczarek2023-02-011-24/+80
| | | | | | | | | | | | | | | | The AJAX script transport has two versions: XHR + `jQuery.globalEval` or appending a script tag (note that `jQuery.globalEval` also appends a script tag now, but inline). The former cannot support the `headers` option which has so far not been taken into account. For jQuery 3.x, the main consequence was the option not being respected for cross-domain requests. Since in 4.x we use the latter way more often, the option was being ignored in more cases. The transport now checks whether the `headers` option is specified and uses the XHR way unless `scriptAttrs` are specified as well. Fixes gh-5142 Closes gh-5193
* Build: Run GitHub Action browser tests on Playwright WebKitMichał Gołębiowski-Owczarek2023-01-234-7/+28
| | | | | | | | | | | | | | | | | | | | | | | | So far, we've been running browser tests on GitHub Actions in Chrome and Firefox. Regular Safari is not available in GitHub Actions but Playwright WebKit comes close to a dev version of Safari. With this change, our GitHub CI & local test runs will invoke tests on all actively developed browser engines on all PRs. Also, our GitHub Actions browser tests are now running on Node.js 18. Detection of the Playwright WebKit browser in support unit tests is done by checking if the `test_browser` query parameter is set to `"Playwright"`; this is a `karma-webkit-launcher` feature. Detecting that browser via user agent as we normally do is hard as the UA on Linux is very similar to a real Safari one but it actually uses a newer version of the engine. In addition, we now allow to pass custom browsers when one needs it; e.g., to run the tests in all three engines on Linux/macOS, run: ``` grunt && BROWSERS=ChromeHeadless,FirefoxHeadless,WebkitHeadless grunt karma:main ``` Closes gh-5190
* Selector: Make selector lists work with `qSA` againMichał Gołębiowski-Owczarek2022-12-191-1/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | jQuery 3.6.2 started using `CSS.supports( "selector(SELECTOR)" )` before using `querySelectorAll` on the selector. This was to solve gh-5098 - some selectors, like `:has()`, now had their parameters parsed in a forgiving way, meaning that `:has(:fakepseudo)` no longer throws but just returns 0 results, breaking that jQuery mechanism. A recent spec change made `CSS.supports( "selector(SELECTOR)" )` always use non-forgiving parsing, allowing us to use this API for what we've used `try-catch` before. To solve the issue on the spec side for older jQuery versions, `:has()` parameters are no longer using forgiving parsing in the latest spec update but our new mechanism is more future-proof anyway. However, the jQuery implementation has a bug - in `CSS.supports( "selector(SELECTOR)" )`, `SELECTOR` needs to be a `<complex-selector>` and not a `<complex-selector-list>`. Which means that selector lists now skip `qSA` and go to the jQuery custom traversal: ```js CSS.supports("selector(div:valid, span)"); // false CSS.supports("selector(div:valid)"); // true CSS.supports("selector(span)"); // true ``` To solve this, this commit wraps the selector list passed to `CSS.supports( "selector(:is(SELECTOR))" )` with `:is`, making it a single selector again.

* Core:Selector: Move jQuery.contains from the selector to the core moduleMichał Gołębiowski-Owczarek2022-12-122-55/+56
| | | | | | | The `jQuery.contains` method is quite simple in jQuery 4+. On the other side, it's a dependency of the core `isAttached` util which is not ideal; moving it from the `selector` the `core` module resolves the issue. Closes gh-5167
* Selector: Implement the `uniqueSort` chainable methodMichał Gołębiowski-Owczarek2022-11-281-22/+56
| | | | | | | | | Some APIs, like `.prevAll()`, return elements in the reversed order, causing confusing behavior when used with wrapping methods (see gh-5149 for more info) To provide an easy workaround, this commit implements a chainable `uniqueSort` method on jQuery objects, an equivalent of `jQuery.uniqueSort`. Fixes gh-5166 Closes gh-5168
* Tests: Indicate Firefox 106+ passes the `cssSupportsSelector` testMichał Gołębiowski-Owczarek2022-11-251-1/+7
| | | | | | Firefox 106 adjusted to the spec mandating that `CSS.supports("selector(...)")` uses non-forgiving parsing which makes it pass the relevant support test. Closes gh-5141
* Selector: Re-introduce selector-native.jsMichał Gołębiowski-Owczarek2022-11-212-3/+25
| | | | | | | | | | | | | | | | | | | | | Re-introduce the `selector-native` similar to the one on the `3.x-stable` branch. One difference is since the `main` branch inlined Sizzle, some selector utils can be shared between the main `selector` module and `selector-native`. The main `selector` module can be disabled in favor of `selector-native` via: grunt custom:-selector Other changes: * Tests: Fix Safari detection - Chrome Headless has a different user agent than Safari and a browser check in selector tests didn't take that into account. * Tests: Run selector-native tests in `npm test` * Selector: Fix querying on document fragments Ref gh-4395 Closes gh-5085
* Selector:Manipulation: Fix DOM manip within template contentsMichał Gołębiowski-Owczarek2022-11-142-0/+53
| | | | | | | | | | | | | | | | The `<template/>` element `contents` property is a document fragment that may have a `null` `documentElement`. In Safari 16 this happens in more cases due to recent spec changes - in particular, even if that document fragment is explicitly adopted into an outer document. We're testing both of those cases now. The crash used to happen in `jQuery.contains`. As it turns out, we don't need to query the supposed container `documentElement` if it has the `Node.DOCUMENT_NODE` (9) `nodeType`; we can call `.contains()` directly on the `document`. That avoids the crash. Fixes gh-5147 Closes gh-5158
* Ajax: Support `null` as success functions in `jQuery.get`Michał Gołębiowski-Owczarek2022-10-171-0/+20
| | | | | | | | | | | | | According to the docs, one can use `null` as a success function in `jQuery.get` of `jQuery.post` so the following: ```js await jQuery.get( "https://httpbin.org/json", null, "text" ) ``` should get the text result. However, this shortcut hasn't been working so far. Fixes gh-4989 Closes gh-5139
* Selector: Drop support for legacy pseudos, test custom pseudosMichał Gołębiowski-Owczarek2022-10-111-0/+74
| | | | | | | | | This backports custom pseudos tests from Sizzle; they were missed in original test backports. Also, the support for legacy custom pseudos has been dropped. The `jQuery.expr` test cleanup has been wrapped in `try-finally` for cleaner test isolation in case anything goes wrong. Closes gh-5137
* Manipulation: Extract domManip to a separate fileMichał Gołębiowski-Owczarek2022-10-101-3/+3
| | | | | | | | | | | We've already had `buildFragment` extracted to a separate file long ago. `domManip` is quite a complex & crucial API and so far it has existed within the `manipulation.js` module. Extracting it makes the module shorter and easier to understand. A few comments / messages in tests have also been updated to not suggest there's a public `jQuery.domManip` API - it's been private since 3.0.0. Closes gh-5138
