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.
Fixes gh-5069
Closes gh-5046
The queue module is not present in the slim build as it depends on deferred
and our Gruntfile specifies excluding deferred should also exclude queue:
https://github.com/jquery/jquery/blob/3.5.1/Gruntfile.js#L66
This commit makes this exclusion explicit so that the queue module never
accidentally gets re-included in the slim build if it stopped importing from
the deferred module directly.
Closes gh-4793
This commit cleans up a few comments & configurations that are out of date
after the migration to ES modules backed by a Rollup-based compilation.
Also, de-indent AMD modules. This will preserve a more similar
structure to the one on 3.x-stable where the body of the main `define`
wrapper is not indented.
Closes gh-4705
So far, the slim build was expanded to its full exclusion list, generating the
following `jQuery.fn.jquery`:
```
v4.0.0-pre -ajax,-ajax/jsonp,-ajax/load,-ajax/script,-ajax/var/location,-ajax/var/nonce,-ajax/var/rquery,-ajax/xhr,-manipulation/_evalUrl,-deprecated/ajax-event-alias,-callbacks,-deferred,-deferred/exceptionHook,-effects,-effects/Tween,-effects/animatedSelector,-queue,-queue/delay,-core/ready
```
This commit changes it to just `v4.0.0-pre slim`. Only the pure slim build is
treated this way, any modification to it goes through the old expansion; e.g.
for `custom:slim,-deprecated` we get the following `jQuery.fn.jquery`:
```
v4.0.0-pre -deprecated,-deprecated/ajax-event-alias,-deprecated/event,-ajax,-ajax/jsonp,-ajax/load,-ajax/script,-ajax/var/location,-ajax/var/nonce,-ajax/var/rquery,-ajax/xhr,-manipulation/_evalUrl,-callbacks,-deferred,-deferred/exceptionHook,-effects,-effects/Tween,-effects/animatedSelector,-queue,-queue/delay,-core/ready
```
Since the version string is also put in the jQuery header comment, it also got
smaller.
Also, the logic to skip including the commit hash in the header comment - when
provided through the COMMIT environment variable which we do in Jenkins - in
minified builds headers has been applied to builds with exclusions as well.
Closes gh-4649
So far, the slim build only excluded ajax & effects modules. As many web apps
right now rely on native Promises, often with a polyfill for legacy browsers,
deferred & callbacks modules are not that useful for sites that already exclude
ajax & effects modules.
This decreases the gzipped minified size of the slim module by 1760 bytes,
to 19706 bytes (below 20k!).
Closes gh-4553
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

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
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
This commit removes Sizzle from jQuery, inlining its code & removing obsolete
workarounds where applicable.
The selector-native module has been removed. Further work on the selector
module may decrease the size enough that it will no longer be necessary. If
it turns out it's still useful, we'll reinstate it but the code will look
different anyway as we'll want to share as much code as possible with
the existing selector module.
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 commit reduces the gzipped jQuery size by 1460 bytes compared to master.
Closes gh-4395
This commit requires all function parameters to be used, not just the last one.
In cases where that's not possible as we need to match an external API, there's
an escape hatch of prefixing an unused argument with `_`.
This change makes it easier to catch unused AMD dependencies and unused
parameters in internal functions the API of which we may change at will, among
other things.
Unused AMD dependencies have been removed as part of this commit.
Closes gh-4381
The previous regex caused the final jQuery binary to have syntax errors for
var-modules with names starting with "return". For example, the following module
wouldn't work when the file is named `returnTrue.js`:
```js
define( function() {
"use strict";
return function returnTrue() {
return true;
};
} );
```
Closes gh-4389
The code replacing @CODE in wrapper.js was written so that it expected
both the code and the next line to start in the first column. This commit
adjusts the regex so to get rid of that assumption and to work properly
regardless of number of lines with comments after this block.
While this is technically not necessary for our code, contributors sometimes
re-format the wrapper file in their pull requests and the error
messages they get don't tell them what's the real problem with their code.
Closes gh-3429
- For compability reasons, we had already added the global
in AMD mode, but without noConflict. This adds back noConflict
to AMD (which fixes noConflict mode in the tests).
Fixes gh-2930
The new regex from after the switch from JSHint to ESLint wasn't catching
the ESLint pragma correctly.
Also, the spacing of the pragma comment was updated to match other comments.
Tracked bower dependencies are located at "src/sizzle" and "test/libs".
The source-destination mapping is in the Gruntfile.
When updating a bower dependency, update the version in bower.json, run
`grunt bower`, and then commit the result. When adding a dependency,
update the bowercopy task accordingly.
Fixes#14615.
Closes gh-1452.
