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
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
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
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.

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
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
So far, we've been testing that jQuery element iteration works with polyfilled
Symbol & transpiled for-of via a Node test with jsdom with the Symbol global
removed. Unfortunately, jsdom now requires Symbol to be present for its internal
functionality so such a test is no longer possible. Instead, it's been migrated
to an iframe test with transpiled JavaScript.
This PR also enables us to use ECMAScript 2017 or newer in Node.js code.
Closes gh-4305
The only packages not fully updated are:
- qunitjs & karma-qunit as that's a QUnit 2.x update that will require some
changes and we'll do that later
- jsdom as we need to first rewrite the test with the Symbol polyfill - newer
jsdom versions don't work with such a hacked Symbol instance
- sinon as the v2 -> v7 upgrade requires to update our unit tests
- uglify-js & grunt-contrib-uglify as latest uglify-js versions slightly worsen
the minified gzipped size
Closes gh-4227
Closes gh-4228
Closes gh-4230
Closes gh-4232
- Update QUnit to 1.23.1
- Remove unused dl#dl from test/index.html
- Remove unused map#imgmap from test/index.html
- Ensure all urls to data use baseURI
- Add the 'grunt karma:main' task
- customContextFile & customDebugFile
- Add 'npm run jenkins' script

Node.js 0.12 is no longer supported by upstream. So far we had to keep
a workaround that would skip running ESLint there (or even load its task)
as it no longer supports Node.js <4; the same applied to Node smoke tests
as jsdom has also dropped support for those old Node versions. Those
workarounds have been removed now.

Closes gh-3478
1. Use the short name of the preset in the config.
2. Run ESLint first on non-minified files.
3. Explicitly specify environments in every config file (those settings cascade
which means we've been assuming a Node.js environment where we shouldn't have).
Currently the "all" target for the eslint task includes way more than
the "dev" & "dist" targets combined and those 2 tasks are the one run in
`npm test`.
ESLint 3.0 drops support for Node.js older than 4.x. To be able to update
to this version and yet not block our contributors from building jQuery
on older Node.js (at least until it's supported by upstream) this commit
makes ESLint skipped on older Node; a proper message is displayed then.
Fixes gh-3222
* Bump eslint-config-jquery package to 0.1.4 version
* Add subtask "dist" to "eslint" task and add it to the build task list
* Make gitignore globs more flexible for the "dist" folder
Fixes gh-3169
The husky Git precommit hook was linting not only the source but also the
built file. Normally it's expected, we want to run basic checks on what's
built but in the precommit hook we're not building the file so we might
be linting some previous, broken version.
Fixes gh-3091
This commit increases the gzipped size by 90 bytes so a better solution
is needed but, at the same time, it disables the very optimizations
that are causing strict mode violations in Firefox 45, Safari 9 & IE 10.
Refs 76084372c2
Refs mishoo/UglifyJS2#1052
All deps were updated except:
* jsdom - tests using a Symbol polyfill are hacky and break with newer jsdom;
we need to re-do them properly first
* qunitjs - versions 1.19.0 & 1.20.0 introduce race conditions to the tests,
making the fail randomly
Those two packages will be updated once issues related to them get resolved.
Fixes gh-2877
