* [npm] remove unused deps
* [ftr] remove digdug, use chromedriver directly
why?
- digdug is meant to be used by intern, and expects a certain lifecycle that the FTR has tried and continuously fails to mimic
- rather than continue trying to force digdug into the stack, just spawn chromedriver ourselves. We know how to handle it
- cleans up verbose remote logging while we're in there, since selenium-standalone-server went with digdug, which was previously doing the verbose logging
- deprecate config.servers.webdriver
- add config.chromedriver.url
- if url at config.chromedriver.url points to a server that responds to http requests use it as the chromedriver instance, enables running chrome in a VM or container
- if pings to config.chromedriver.url fail a local chromedriver is started
* address review requests
* Reactify the confirmation modal
Up next: jest tests
* Add tests
- Relies on https://github.com/elastic/kibana/pull/10821 getting
checked in first for commonHtmlProps
* Don't include the overlay as part of the confirm modal component
* Use the react version of a confirmation modal
- Can’t use the modalOverlay or it would be two nested react roots, due
to the way it’s embedded in angular.
* Add snapshots
* Fix tests
* fix confirm_modal_promise tests
I have no idea why the introduction of react would cause this to fail
as it was, but for some reason, grabbing the button reference has to be
after the digest loop.
* Address code review comments
* switch over the remaining React.PropType references (in the modals dir anyway)
* Add a react tool bar search box
Create basic react toolbar elements and update uiframework docs
* Package.json: put back ngreact (edits got overwritten)
* Add jest tests
* Combine basic tests into one, eliminate helper functions
* Address code review comments
- move tool_bar_footer into it’s own file.
- some stylistic html changes
- comments
* Remove toolbar_with_search_only
It isn’t being used in kibana currently, so we probably don’t need to
support it in our ui_Framework, and the need for the custom
“className="kuiToolBar--searchOnly”” indicates we should resdesign it
if we do need it some day.

Previously our plugin installation used over 5,000 file descriptors when analyzing and extracting the archive. To mitigate this, we are moving to a more supported zip library, Yauzl.
In addition to the replacement of the zip library, this refactors the getPackData method. It was extracting the plugin package.json files, reading them, then finally deleting them. This commit performs this all in memory, removing the need for any file system operations during this step.
These changes reduced the installation time by an average of 35%, from 211.18 seconds to 137.8 seconds. The majority of this time is now spent during optimize.

* As a part of bringing functional testing to plugins, esArchiver gives these plugins a way to capture and reload es indexes without needing to write a bunch of custom code. It works similarly to the elasticDump and ScenarioManager tools that it replaces.
Differences:
- Streaming implementation allows for much larger archives
- CLI for creating and using archives
- Configurable archive location
- Stores the data in gzipped files (better for source control, searching, large archives)
- Automatically identifies and upgrades Kibana config documents
Methods:
- `#load(name)`: import an archive
- `#loadIfNeeded(name)`: import an archive, but skip the documents what belong to any existing index
- `#unload(name)`: delete the indexes stored in an archive
CLI operations:
- `./bin/es_archiver save <name> [index patterns...]`: save the mapping and documents in one or more indexes that match the wild-card patterns into an the `<name>` archive
- `./bin/es_archiver load <name>`: load the mapping and documents from the `<name>` archive

* [npm] upgrade babel
The upgrade to babel 6 requires an upgrade to all of the associated modules, which meant that a few other things changed at the same time. The most notable is the way that we handle our babel-options, which is now done with an npm module and includes using the babel-loader's "presets" query string param.
This meant changes to the babel_options.js module and extending it to help setting up the "babel-register" module, which was previously copy-pasted in several places.
* [mtodules] upgrade to support babel6 module semantics
* [eslint] fix lint errors
* [babel] ignoer massive fixture files
* [cli/errors] use Object.setPrototypeOf since subclassing Error is broken
* [babel] Upgrading core babel libraries

* [babel/options] resolve preset/plugins paths for better plugin compatibility
* [babel/options] use babel-preset-env for correct node settings

Remove libsass as a dependency
libsass is platform specific, therefore we can not ship it as a dependency. Instead, we will commit the compiled CSS for the UI Framework to the repository. This is updated when running `npm run uiFramework:start` which also starts the docs site.

* [webpack] upgrade to @elastic/webpack-directory-name-as-main v2
* bump @elastic/webpack-directory-name-as-main
* import browser mocha with webpackShim
`import 'mocha'` will resolve to `mocha/index.js`, which points to
`mocha/lib/mocha.js`, the node version of mocha. This will not work in
the browser.
Since ng_mock is browser code, we need the mocha build for the browser,
which lives at `mocha/mocha.js`. This isn't referenced at all in the
package.json file, but is references in the bower.json file. Webpack,
however, doesn't observe the bower config, so we need to specifically
reach into the mocha package and point to the `mocha/mocha.js` file.
- Icon, Link, Button, TextInput, CheckBox, Table, ControlledTable, ToolBar, ToolBarFooter.
- Update Local Nav to use classes with kui prefix.
- Add PostCSS loader to UI Framework webpack.
* Add low level i18n plugin
Manages languages that are available and is responsible for loading translated
content at the granularity of a plugin.
To be done:
- APIs for store and retrieval
* Use Kibana install as root for the translation store directory
Setting the path for storing the bundled language translation files to
<KIBANA_INSTALL>/data/store_translations/<PLUGIN_NAME>
* Updated i18n core plugin APIs to be asynchronous
To be done:
- Better error handling in APIs
- Fix threading issue with storePluginLanguageTranslations API
* Fix thread synchroization issue in storePluginLanguageTranslations
* Update error handling in i18n core plugin
* Change to use NodeJS mkdirp function for creating directories recursively
Updates with review comments from @srl295. Changed export syntax to show the
exported functions at end of file.
* Add REST API for getting translations of a language for a plugin
To be done:
- Add algorithm to decide on the language for a plugin by comparing the accept languages
from the REST call and the plugin supported languages
- Add REST API tests
* Add algorithm for determining plugin language when retrieving translations
Client would pass languages used in the 'accept-language' header. These
languages would then be compared against the plugin supported languages
and best compared language would be selected.
To be done:
- Add REST API tests
* Add API to return all registered plugin language translations
* Add HAPI API to get all plugins translation files
* Update register translations API to be independent of plugin name and language
The register API is updated to be independent of plugin name and language. The API will now
traverse the path given and create language bundles as per language files it traverses.
The translations files structure has also been simplified to be just key/value objects.
To be done:
- Add hapi API to get translations
- Extend the API tests to test responses
* Update API test
* Add eslint fix for API test
* Update with review comments
From review https://github.com/elastic/kibana/pull/7545#issuecomment-231147435
following comments updated:
- README, .gitignore, and .eslintrc are not needed in a core plugin
- package.json only needs name and version
- unit tests need to go in a tests directory otherwise they won't get picked up
by the grunt tasks. Also our convention is to name the test file with the same
name as the module it's testing (so i18n_tests.js should just be i18n.js)
- For consistency with the rest of the code base, rename the data directory to fixtures.
- Prefer const (or let if necessary). Don't use var.
- Use ES6 imports/exports rather than commonjs style
- Only export the i18n module's public API. For instance, I don't think getPluginTranslationDetails is used outside of the i18n module, so it shouldn't be exposed publicly. If you want to expose it for testing purposes, I would recommend creating an i18n directory with an index.js file that exports the module's public API, and a separate i18n.js file with the "private" API. index.js will be for public use, i18n.js will be for private internal use.
* Update after review comments
From review (https://github.com/elastic/kibana/pull/7545#issuecomment-231884490):
- i18n module API should return promises for async operations instead of using
callbacks
- All filesystem access should be async
- Unit tests need to be updated based on new proposed plugin structure
(single language file, not split by view)
From design (https://github.com/elastic/kibana/issues/6515#issuecomment-231400097):
- Removed API as will consider in later phase
TODO:
- Make write function async
* Update after review comments
Updated write function to be asynchronous
* Update registerTranslations API to take absolute translation file as argument
The API originally took the directory as the argument but following reviews it
was decided to change to absolute file because it will be less brittle
since it is more explicit.
* Translate the Kibana welcome message
Translates the start-up message (“Kibana is loading ...”)in the Jade template.
To be done:
- Means to register the core plugin translations. They are currently added
in the fixtures directory as static files. Need to be generated on the fly.
* Add build task to generate core plugin translations
Task which calls registerTranslations API and then a task which copies the
regsitered translations to <kibana_root>/build/kibana
* Add hook to optimize module to add registration during dev startup
Registration of the core plugin translations during development start of
Kibana server. The translations include the welcome message and server error
startup message.
* Handle scenario when the user preferred language header is not passed
The UI when loading asks i18n plugin which language translation to use
depending on the user preferred language header 'accept-language'.
This commit is to handle scenario where header is not passed. The algorithm
then chooses the default language.
* Replace registering of translations at plugin install time to the plugin init phase

* Fill any missing translations using translations from default locale
The default language translations are loaded and are compared against the selected
language translations. The comparison can then highlight any missing translation
keys and can load the default translations keys as needed. This helps to unsure
where possible that a translation string is available in most scenarios even if not
in the locale requested.

Updated the following review comments:
https://github.com/elastic/kibana/pull/7545#pullrequestreview-9297662
* Update the algorithm to return the locale
The algorithm to return which locale to use for translations based on the user
locale list and the regsitered locales is updated in this commit. The algorithm
previously did an exact match on all the user locales first before (by priority)
then checking for best case match. The algorithm is now modified to check each
user locale starting with the highest priority first for an exact match and then
for best case match. If no match it then moves to the next user locale with
the next highest priority. This is to follow the priority list that a user
browser is configured for where there maybe a locale translation available
but might not be the exact match with regard to the locale code and/or script.
An example of this is that the highest priority locale of the user is 'en-US'
but the locale translation available is 'en'. It is better select the 'en'
locale rather than select the next highest locale which is an exact match.

This commit is for updates after the following review:
https://github.com/elastic/kibana/pull/7545#pullrequestreview-10435175
* Fix issue when unit test run in CI as core translations are registered
When unit tests are run on a test server (like in the CI), it will start
Kibana server and register the core translations. This means that the i18n
unit tests need to be able to store the existing registration prior to
testing and replace after testing.
* [server/ui] move i18n into ui module
* [server/ui] restore renderApp() method signature
* [server/ui] unify i18n logic in UiI18n class
* [server] move translation files into "translations" dir
* Update i18n module to loaded by multiple server instances within the one process
* Update i18n module to a class
Moving the i18n module into a class so as to encapsulate the registered
translations which means there can be different and distinct instances per process.
This is to accomodate the user case where there might be multiple Kibana server
instances in a process and the localization should be at the server level.
* Identify private members in a class with underscore-prefix convention
* Remove redundant translation from core translation file
Message starting with 'Give me a moment...' is no longer part of loading
