7fabf32172 feat(executioncontext): warn on nested js handle (#3591)
ExecutionContext.evaluateHandle accepts arguments that are either
serializable, or JSHandles. A potential confusion is that it *does not*
accept arguments that *contain* JSHandles.

This patch adds a log message warning when it encounters that situation.

Fixes #3562

81edbbb58e fix(clicking): handle negative area results in computeQuadArea (#3413)
This patch fixes a case in which computeQuadArea calculates the area size correctly, but returns the area as a negative number.
This occurs when DOM.getContentQuads returns quads in a specific order.

E.g. the array: [ { x: 463, y: 68.5 },{ x: 437, y: 68.5 },{ x: 437, y: 94.5 },{ x: 463, y: 94.5 } ] will receive area size of -676.

3d7ae2a259 fix: fix null-type bugs (#3137)
I ran TypeScript against our code with `strictNullChecks` on. Most of the errors generated are noise, because TypeScript doesn't understand how our `assert` method works. But some were legitimate bugs. They are fixed in this patch.

refactor: drop object factory from execution context (#3099)
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.

fix: revert ExecutionContext reporting. (#3058)
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.

73f9c48081 feat: nicer protocol error messages (#2742)
This patch:
- stops appending `undefined` to our protocol messages unnecessarily.
- rewrites `Cannot find execution context id` to `Execution context was destroyed, most likely because of a navigation.` when it occurs from a Puppeteer ExecutionContext. The error message is left alone if it occurs via a CDPSession.

chore: stop using console.assert everywhere (#2646)
Since Node 10, `console.assert` no longer throws an AssertionError.
(This is generally good since it aligns Node.js with Browsers.)

This patch migrates all usages of `console.assert` in our codebase.
- All the `lib/` and testing code is migrated onto a handmade `assert`
function. This is to make Puppeteer transpilation / bundling easier.
- All the tooling is switched to use Node's `assert` module.

Fixes #2547.

93fe2b57d6 feat(Page): introduce workers (#2560)
This adds `page.workers()`, and two events `workercreated` and `workerdestroyed`. It also forwards logs from a worker into the page `console` event.

Only dedicated workers are supported for now, ServiceWorkers will probably work differently because they aren't necessarily associated with a single page.

Fixes #2350.

fix(Frame): postpone evaluations until execution context gets created (#1415)
In Blink, frames don't necesserily have execution context all the time.
DevTools Protocol precisely reports this situation, which results in
Puppeteer's frame.executionContext() being null occasionally.

However, from puppeteer point of view every frame will have at least a
default executions context, sooner or later:

- frame's execution context might be created naturally to run frame's
  javascript
- if frame has no javascript, devtools protocol will issue execution
  context creation

This patch builds up on this assumption and makes frame.executionContext()
to be a promise.
As a result, all the evaluations await for the execution context to be created first.

Fixes #827, #1325

BREAKING CHANGE: this patch changes frame.executionContext() method to return a promise.
To migrate onto a new behavior, await the context first before using it.

5c92ba222a fix(page.evaluate): jsonValue should ignore toJSON property (#1098)
Currently, JSHandle.jsonValue() is implemented as in-page JSON.stringify
call and consequent JSON.parse in node. This approach proved to be
unfortunate for automation purposes: if page author overrode the
Object.prototype.toJSON method, then it's harder for puppeteer to
interact with the page.

This patch switches JSHandle.jsonValue to use protocol serialization
that ignores toJSON property. THis also changes the `page.evaluate`
behavior since it is based on JSHandle.jsonValue().

Fixes #1003.

BREAKING CHANGE:
`page.evaluate` no longer calls toJSON when generating return value.
For the old behavior, do JSON.parse/JSON.stringify manually:

```js
const json = JSON.parse(await page.evaluate(() => JSON.stringify(obj)));
```
