Migrations are the mechanism by which saved object indices are kept up to date with the Kibana codebase. Plugin authors can write their plugins to work with a certain set of mappings. Migrations ensure that the index actually conforms to those expectations.
I was surprised when I tried to spread a `Set` in TypeScript and the browser complained about `Set.slice()` not being defined. This is because TypeScript does not automatically enable support for iterators when targeting earlier ES versions, like we do in the browser, unless you use the `"downlevelIteration": true` compiler option. This injects some helpers into the necessary files for reading/spreading iterators, which can be stuffed behind an import statement with using the `"importHelpers": true` compiler option and include `tslib` in our dependencies. This is already a dependency of several of our packages, so it shouldn't cause any additional modules.
I'd really like to upgrade to Typescript 3 for its `unknown` type, but we need to upgrade to `jest@23` to support a recent version of `ts-jest@23`.
The [jest changelog](https://github.com/facebook/jest/blob/master/CHANGELOG.md) breaks down the breaking changes in 23.x, but I found it to be slightly incomplete so I've broken down the changes that actually caused breaks for us here, and addressed each in individual commits to make review a little easier:
- the `testURL` config default was changed from `about:blank` to `http://localhost`
- this cause some XHR requests powered by JSdom to start failing. It seems these requests just do nothing in master but start to fail when JSdom is initialized with an actual URL... I think we would ideally stop sending meaningless XHR requests in the tests, but it was a lot easier to just set the config to `about:blank` for now, and we can worry about cleanup later if necessary
- `expect(...).toThrow()` only passes if an actual error was thrown.
- In two places in the index pattern code we were throwing strings, which broke the assertions. Fortunately/Unfortunately the errors are not being consumed by anything, so I was able to wrap them in `new Error()` without causing any issues.
- snapshots of mock functions now include a `results` array, detailing the return values of the function
- React fragments are now serialized as `<React.Fragment>` instead of `<UNDEFINED>`
- undefined props in React components are now stripped from snapshots
- minor changes to the ordering of mocks, imports resolution, and before hooks caused the uiSettings API tests to start breaking, but I'm replacing them with totally new tests in #22694 so I just deleted them here
- mocks created with `jest.spyOn()` that are restored now have their `mock.calls` reset, so some of the kbn-pm tests stated failing. This was fixed by restoring them with `jest.restoreAllMocks()` rather than trying to do it before the assertions
This is an attempt to write a log capture integration for the functional test runner that will collect all log output written during a test, prevent it from being written to stdout to lower the amount of work Jenkins master has to do and include the entire log output for each test in the junit report. I'm slightly concerned about the amount of memory we'll be using to store a copy of the logs for each test, but streaming the XML report isn’t easy and there doesn’t seem to be a library out there to help. If we decide it’s torally necessary we might be able to figure it out.
This adds support for autoprefixer which we have been using in Webpack.
Additionally, we have improved the watching functionality and now update builds based directly on their dependencies an not an assumption that the files are children.

This upgrades prettier to version 1.14.0. The main motivation is to gain support for the new TypeScript language features introduced in 2.9 and 3.0.
Prettier versions 1.13 and 1.14 also introduced some other JavaScript and TypeScript style improvements resulting in a few small line break and parenthesis changes.
The relevant release notes are:
* [Prettier 1.13.0 Release Notes](https://prettier.io/blog/2018/05/27/1.13.0.html)
* [Prettier 1.40.0 Release Notes](https://prettier.io/blog/2018/07/29/1.14.0.html)
In order to make the awesome new kfetch api easier to consume in purely TypeScript projects, and since it's a pretty small module with very few dependencies, I converted it to TypeScript.
Along with kfetch I also started a type definition file for `ui/chrome` that we can extend as we go, but will likely be unnecessary after #19992
* bump eui
* Fixed breaking `EuiPage` changes
Mainly adding `EuiPageBody`’s where there were none
* bump to 3.0, remove duplicate declaration of EuiFlyoutBody, update jest snapshots
* bump eui
* bump to 3.0, remove duplicate declaration of EuiFlyoutBody, update jest snapshots
* Update jest snapshots in xpack
This upgrades TypeScript to version 2.9.2. My main motivation is the support for generic type arguments in JSX elements and tagged templates (e.g. for `styled-components`).
Problems arising from breaking changes in the new TypeScript version have been mitigated by:
* setting the `keyofStringsOnly` option until impacted code has been
future-proofed
* Restricting some joi-related generics
See the [release notes](https://www.typescriptlang.org/docs/handbook/release-notes/typescript-2-9.html) for details.
Some follow-up tasks should be:
* Update EUI to support the new `keyof` behaviour
* Update new platform TypeScript code to support new `keyof` behaviour
* Remove `keyofStringsOnly` setting
