A newly added test making sure a native selector containing
the `:valid` pseudo works when no jQuery-specific selectors
are used was failing in IE 9 as that browser lacks support
for this pseudo. This commit disables that test in IE 9.
Selector: Make selector lists work with `qSA` again
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.
Selector: Implement the `uniqueSort` chainable method
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`.
Selector: Inline Sizzle into the selector module: 3.x version (#5113)
This commit removes Sizzle from jQuery, inlining its code & removing obsolete
workarounds where applicable.
The Sizzle AUTHORS.txt file has been merged with the jQuery one - people are
sorted by their first contributions to either of the two repositories.
The main `selector` module can be disabled in favor of `selector-native`
via:
grunt custom:-selector
For backwards compatibility, the legacy `sizzle` alias is also supported (it
will be dropped in jQuery `4.0.0`):
grunt custom:-selector
Sizzle tests have been ported to jQuery ones. Ones that are not compatible
with the `selector-native` module are disabled if the regular selector module
is excluded.
Backwards compatibility is still kept for all `Sizzle` utils - they continue to be
available under `jQuery.find` - but the primary implementation is now attached
directly to jQuery.
Some selector utils shared by `selector` & `selector-native` have been
extracted & deduplicated. `jQuery.text` and `jQuery.isXMLDoc` have been
moved to the `core` module.
The commit reduces the gzipped jQuery size by 851 bytes compared to the
`3.x-stable` branch.

Build: Limit permissions for GitHub workflows
Add explicit permissions section[^1] to workflows. This is a security
best practice because by default workflows run with extended set
of permissions[^2] (except from `on: pull_request` from external forks[^3].
By specifying any permission explicitly all others are set to none. By using
the principle of least privilege the damage a compromised workflow can do
(because of an injection[^4] or compromised third party tool or action) is
restricted. It is recommended to have most strict permissions on the top
level[^5] and grant write permissions on job level[^6] on a case by case
basis.
Selector:Manipulation: Fix DOM manip within template contents
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` which is an alias for
`Sizzle.contains` in jQuery 3.x.
The Sizzle fix is at jquery/sizzle#490, released in Sizzle `2.3.8`. This
version of Sizzle is included in the parent commit.
A fix similar to the one from gh-5158 has also been applied here to the
`selector-native` version.
This will resolve the following security issues:
* Path Traversal in Grunt: https://github.com/advisories/GHSA-j383-35pm-c5h4
* Race Condition in Grunt: https://github.com/advisories/GHSA-rm36-94g8-835r
The previous details were showing their age, e.g. mentions about browsers
not supporting ES2015. The story with ES modules is more complex as it's also
about loaders but to keep the README simple, let's just make it more up to date
with typical usage.
Tests: Remove a workaround for a Firefox XML parsing issue
Firefox 96-100 used to report the column number smaller by 2 than it should
in the `parsererror` element generated for invalid XML documents. Since that
version range is unsupported now and it includes no ESR versions, the workaround
can now be dropped.
CSS: Return `undefined` for whitespace-only CSS variable values (#5120)
The spec requires that CSS variable values are trimmed. In browsers that do
this - mainly, Safari, but also Firefox if the value only has leading
whitespace - we currently return undefined; in other browsers, we return
an empty string as the logic to fall back to undefined happens before
trimming.
This commit adds another explicit callback to `undefined` to have it consistent
across browsers.
Also, more explicit comments about behaviors we need to work around in various
browsers have been added.
Accept "HTTP/2.0 200" as a valid `statusText` for successful requests
to make ajax tests pass in iOS 9. At this point, normalizing this in code
doesn't seem to make a lot of sense.
Deprecated: Improve $.trim performance for strings with lots of whitespace
Regex imp implementation takes `O(N^2)` time to trim the string when
multiple adjacent spaces were present.
The new expression require that the "whitespace run" starts from
a non-whitespace to avoid `O(N^2)` behavior when the engine would
try matching `\s+$` at each space position.
Tests: Exclude tests based on compilation flags, not API presence (3.x version)
Introduces a new test API, `includesModule`. The method returns whether
a particular module like "ajax" or "deprecated" is included in the current
jQuery build; it handles the slim build as well. The util was created so that
we don't treat presence of particular APIs to decide whether to run a test as
then if we accidentally remove an API, the tests would still not fail.
Build: Test on Node 17, update Grunt & `karma-*` packages
This adds testing on Node.js 17 in addition to the currently tested 10, 12, 14
and 16 versions.
Also, update Grunt & `karma-*` packages.
Testing in Karma on jsdom is broken in Node 17 at the moment; until we find
a fix, this change disables such testing on Node 17 or newer.
Node smoke tests & promises aplus tests are disabled on Node.js 10 as they
depend on jsdom and the latest jsdom version doesn't run properly on Node 10.
CSS: Skip falsy values in `addClass( array )`, compress code
This change makes jQuery skip falsy values in `addClass( array )`
& `removeClass( array )` instead of stopping iteration when the first falsy
value is detected. This makes code like:
```js
elem.addClass( [ "a", "", "b" ] );
```
add both the `a` & `b` classes.
The code was also optimized for size a bit so it doesn't increase the
minified gzipped size.
Docs: Replace `#NUMBER` Trac issue references with `trac-NUMBER`
This is a version of gh-4993 for the `3.x-stable` branch.
The GitHub UI treats `#NUMBER` as referring to its own issues which is confusing
when in jQuery source it's usually referring to the old deprecated Trac instance
at https://bugs.jquery.com. This change replaces all such Trac references with
`trac-NUMBER`.
A few of the references came with the Sizzle integration and referred to the
Sizzle GitHub bug tracker. Those have been replaced with full links instead.
A new entry describing issue reference conventions has been added to README.
Neither of the removed links is crucial; one of them refers to a site that has
since started being malicious; while the Web Archive links remain safe, some
scanners warn about such links. Removing them is the safest thing to do.

CSS: Justify use of rtrim on CSS property values
CSS does not acknowledge carriage return or form feed characters
as whitespace but it does replace them with whitespace, making it
acceptable to use `rtrim`.
TestSwarm is now proxied via Cloudflare which cuts out headers relevant for
ETag tests, failing them. We're still running those tests in Karma on Chrome
& Firefox (including Firefox ESR).
Tests: Allow statusText to be "success" in AJAX tests
In HTTP/2, status message is not supported and whatever is reported as
statusText differs between browsers. In Chrome & Safari it's "success", in
Firefox & IE it's "OK". So far "success" wasn't allowed. This made the tests
pass locally if you're running an HTTP/1.1 server but on TestSwarm which is
now proxied via an HTTP/2-equipped Cloudflare, the relevant test started failing
in Chrome & Safari.
Docs: Update the URL to the latest jQuery build in CONTRIBUTING.md
It used to say https://code.jquery.com/jquery.js but that's a frozen URL
to jQuery 1.11.1. Let's switch that to the URL to the Git build, i.e.
https://releases.jquery.com/git/jquery-git.js.
Tests: Make Karma browser timeout larger than the QUnit one
Since the default Karma browser no activity timeout was lower than the QUnit
timeout, a single timing out test was interrupting the whole test run of
a browser.
The QUnit timeout is set to 1 minute so I set the Karma one to 2 minutes.
Docs: Remove the CLA checkbox in the pull request template
The EasyCLA status check is required so this won't get missed. The old JSF CLA
is dead, the provided link doesn't return meaningful information. There's no
good replacement link for the old CLA; PR authors are just supposed to sign the
new CLA by clicking on a link posted by the EasyCLA bot when they submit their
first PR since EasyCLA was enabled for the repo.
Manipulation: Don't remove HTML comments from scripts
When evaluating scripts, jQuery strips out the possible wrapping HTML comment
and a CDATA section. However, all supported browsers are already doing that
when loading JS via appending a script tag to the DOM which is how we've been
doing `jQuery.globalEval` since jQuery 3.0.0. jQuery logic was imperfect, e.g.
it just stripped the `<!--` and `-->` markers, respectively at the beginning or
the end of the script contents. However, browsers are also stripping everything
following those markers in the same line, treating them as single-line comments
delimiters; this is now also mandated by ECMAScript 2015 in Annex B. Instead
of fixing the jQuery logic, just let the browser do its thing.
We still need to strip CDATA sections for backwards compatibility. This
shouldn't be needed as in XML documents they're already not visible when
inspecting element contents and in HTML documents they have no meaning but
we're preserving that logic for backwards compatibility. This will be removed
completely in 4.0.
Event: Don't break focus triggering after `.on(focus).off(focus)`
The `_default` function in the special event settings for focus/blur has
always returned `true` since gh-4813 as the event was already being fired
from `leverageNative`. However, that only works if there's an active handler
on that element; this made a quick consecutive call:
make subsequent `.trigger( "focus" )` calls to not do any triggering.
The solution, already used in a similar `_default` method for the `click` event,
is to check for the `dataPriv` entry on the element for the focus event
(similarly for blur).
Tests: Strip untypical callback parameter characters from mock.php
Only allow alphanumeric characters & underscores for callback parameters.
The change is done both for the PHP server as well as the Node.js-based version.
This is only test code so we're not fixing any security issue but it happens
often enough that the whole jQuery repository directory structure is deployed
onto the server with PHP enabled that it makes is easy to introduce security
issues if this cleanup is not done.
Tests: Fix tests for not auto-executing scripts without dataType
Two issues are fixed in testing for responses with a script Content-Type not
getting auto-executed unless an explicit `dataType: "script"` is provided:
* the test is now using a correct "text/javascript" Content-Type; it was using
"text/html" until now which doesn't really check if the fix works
* the Node.js based version of the tests didn't account for an empty `header`
query string parameter

Dimensions: Modify reliableTrDimensions support test to account for FF
Firefox incorrectly (or perhaps correctly) includes table borders in computed
dimensions, but they are the only one. Workaround this by testing for it and
falling back to offset properties
Tests: Skip the jQuery.parseXML error reporting test in Legacy Edge
Legacy Edge, similarly to IE, doesn't report XML parsing errors but just tries
to render the invalid document. Skip the error reporting test there, Edge Legacy
will return a generic "Invalid XML" error, just like IE.
Tests: Fix the jQuery.parseXML error reporting test
Changes:
* Remove incorrect `QUnit.testUnlessIE` usage as that util is only available
on `master`, not here.
* Change `firstCall.lastArg` to `firstCall.args[ 0 ]` as the former API is not
available in older Sinon versions.
due to their synchronous nature everywhere outside of IE the hack added in
gh-4279 to leverage native events causes the native `.focus()` method to be
called last for the initial element, making it steal the focus back. Since
the native method is already being called in `leverageNative`, we can skip that
final call.
This aligns with changes to the `_default` method for the `click` event that
were added when `leverageNative` was introduced there.
A side effect of this change is that now `focusin` will only propagate to the
document for the last focused element. This is a change in behavior but it also
aligns us better with how this works with native methods.
Event: Don't crash if an element is removed on blur
In Chrome, if an element having a `focusout` handler is blurred by
clicking outside of it, it invokes the handler synchronously. If
that handler calls `.remove()` on the element, the data is cleared,
leaving private data undefined. We're reading a property from that
data so we need to guard against this.
Tests: Recognize callbacks with dots in the Node.js mock server
This aligns the Node.js server with the previous PHP one in sending `mock.php`
as a callback if there's no `callback` parameter in the query string which is
triggered by a recently added test. This prevents the request crashing on that
Node.js server and printing a JS error:
```
TypeError: Cannot read property '1' of null
```

Ajax: Execute JSONP error script responses
Issue gh-4379 was meant to be a bug fix but the JSONP case is a bit special:
under the hood it's a script but it simulates JSON responses in an environment
without a CORS setup and sending JSON payloads on error responses is quite
typical there.
This commit makes JSONP error responses still execute the payload. The regular
script error responses continue to be skipped.
The way warning against number values in `.css()` setters was done in
jquery/jquery-migrate#337 and later refined in jquery/jquery-migrate#348
there's no need to send px-ed strings for `top` & `left` as they already
don't get the "px" suffix.

Tests: Fix flakiness in the "jQuery.ajax() - JSONP - Same Domain" test
The "jQuery.ajax() - JSONP - Same Domain" test is firing a request with
a duplicate "callback" parameter, something like (simplified):
```
mock.php?action=jsonp&callback=jQuery_1&callback=jQuery_2
```
There was a difference in how the PHP & Node.js implementations of the jsonp
action in the mock server handled situations like that. The PHP implementation
was using the latest parameter while the Node.js one was turning it into an
array but the code didn't handle this situation. Because of how JavaScript
stringifies arrays, while the PHP implementation injected the following code:
```js
jQuery_2(payload)
```
the Node.js one was injecting the following one:
```js
jQuery_1,jQuery_2(payload)
```
This is a comma expression in JavaScript; it so turned out that in the majority
of cases both callbacks were identical so it was more like:
```js
jQuery_1,jQuery_1(payload)
```
which evaluates to `jQuery_1(payload)` when `jQuery_1` is defined, making the
test go as expected. In many cases, though, especially on Travis, the callbacks
were different, triggering an `Uncaught ReferenceError` error & requiring
frequent manual re-runs of Travis builds.
This commit fixes the logic in the mock Node.js server, adding special handling
for arrays.
