Stephen Niedzielski 95047ba360 Fix: code coverage
Replace Istanbul with nyc, Istanbul's CLI. nyc appears to have some
bugs that this patch works around:

  - When all files in the project are considered, not just those
    imported via tests, the coverage rates and line numbers vary between
    runs. This patch disables the `all` option for now and points to the
    bug:
    https://github.com/istanbuljs/nyc/issues/537#issuecomment-390814662.

  - Source map line numbers appear to be incorrect except when `all` is
    enabled and working correctly (see previous bullet).

  - `sourceMap` must be disabled to avoid ENAMETOOLONG errors when nyc
    tries to include them as encoded strings. The patch disables the
    setting and points to: https://github.com/istanbuljs/nyc/issues/847.
    Using babel-plugin-istanbul and source-map-support appears to have
    no effect (the former in tests/node-qunit/run.js and .babelrc).

  - CI fails with
    `Error: EACCES: permission denied, mkdir '/nonexistent'`. Specify
    `SPAWN_WRAP_SHIM_ROOT` instead of constructing a subdirectory from a
    nonexistent home directory.

Popups

mediawiki/extensions/Popups

See https://www.mediawiki.org/wiki/Extension:Popups for more information about what it does.

Development

Popups uses an asset bundler so when developing for the extension you'll need to run a script to assemble the frontend assets.

You can find the frontend source files in src/, the compiled sources in resources/dist/, and other frontend assets managed by resource loader in resources/*.

After an npm install:

  • On one terminal, kickstart the bundler process:
    • npm start Will run the bundler in watch mode, re-assembling the files on file change.
    • npm run build Will compile the assets just once, ready for deployment. You must run this step before sending the patch or CI will fail (so that sources and built assets are in sync).
  • On another terminal, run tests and linting tools:
    • npm test To run the linting tools and the tests.
      • You can find the QUnit tests that depend on running MediaWiki under tests/qunit/
      • You can find the isolated QUnit tests under tests/node-qunit/, which you can run with npm run test:node
    • We recommend you install a file watcher like nodemon to watch sources and auto run linting and tests.
      • npm install -g nodemon
      • Example running linting and node unit tests:
        • nodemon -w src/ --exec "grunt lint:all && npm run test:node"
    • Get code coverage report with npm run coverage
      • Reports printed in the coverage/ folder

Developers are likely to work with local MediaWiki instances that do not have content to test with. To reduce this pain, you can create a single page with a list of links that point to an existing and external wiki by using the following config flag:

$wgPopupsGateway = 'restbaseHTML';
$wgPopupsRestGatewayEndpoint = 'https://en.wikipedia.org/api/rest_v1/page/summary/';

Popups works with a local copy of the Mobile Content Service too:

$wgPopupsGateway = 'restbaseHTML';
$wgPopupsRestGatewayEndpoint = 'http://localhost:6927/en.wikipedia.org/v1/page/summary/';
