This patch:
- merges `ElementHandle` into `ExecutionContext` (for simplicity; there's no good reason to have them in separate files).
- removes the necessity to pass handle factory when creating `ExecutionContext`
This makes it easier to create execution contexts out of payloads.
References #1215
It turned out that almost any usecase requires helper methods to access
DOM inside the ExecutionContext.
Instead of exposing execution contexts as-is, we should introduce
IsolatedWorld as a first-class citizen that will hold execution contexts
inside.
This patch adds a new require, `puppeteer/Errors`, that
holds all the Puppeteer-specific error classes.
Currently, the only custom error class we use is `TimeoutError`. We'll
expand in future with `CrashError` and some others.
Fixes#1694.
This allows us:
- dogfood browser contexts the way we want them to be used
- simplifies the dance around service workers / cookies setting up and tier down.
When an evaluation causes a navigation, for example:
```js
await page.evaluate(() => window.reload());
```
sometimes we process the ExecutionContextDestroyed event before the ack from the evaluate. When we do get the ack from the evaluate, we try to build a JSHandle for it, and try to find the execution by id. But it is gone, and we throw an error. This patch switches createJSHandle to accept an ExecutionContext instead of just an id.
This bug was making the test `should throw a nice error after a navigation` flaky.
In accordance with its declared type, `Map<string, Function>`.
Currently, it is used as a plain old JS object. The compiler marks this
usage as an error when `noImplicitAny: true`. This change switches to
use the appropriate Map methods `has/get/set`.
Fixes#3000
This changes sendCharacter to use document.execCommand instead of sending a `'char'` event from the protocol. This is more aligned with how input would come in from emoji keyboards, and removes the 3ish byte limit on characters that can be sent which prevented larger emoji from being rendered correctly.
Emoji will still fail to type correctly if typing them into an iframe that is in shadow dom.

This patch rolls Chromium to r579032. The patch includes:
- https://crrev.com/577366 - DevTools: report redirect responses only if response interception is enabled
- https://crrev.com/577212 - DevTools: intercept requests resulting from redirects
- https://crrev.com/578934 - DevTools: Add a protocol method to insertText
Interception Logic in DevTools protocol has changed regarding redirects;
this patch migrates interceptions to dispatch "request" events based on
requestWillBeSent event.
I have seen some flaky test failures where it would be nice to have run the tests with `DEBUG=puppeteer:error`. Instead of always running tests like that, I am redirecting `debugError` to the output category of the test. This is the same thing that we do for Chromium's stderr.
As a drive-by, I added an additional `debugError` where we were usually a try..finally pattern.
When process is spawned with the 'pipe' set for stdout and stderr, Node expects these streams to be actually dispatched. If we don't, write into pipe becomes blocking and chrome stalls.
We work around that via setting 'ignore' to the stdin, stdout and stderr when the pipe communication channel is used.
Chrome Headless used to open about:blank by default; however, this
was recently changed.
We should open starting page no matter what to keep the environment
predictable.
