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.
This patch:
- updates `utils/fetch_devices.js` script to format UAs for Chrome UAs
and to add iPhone 6/7/8 as separate devices.
- re-generates `DeviceDescriptors.js` with the new script
Fixes#2730.
This patch eliminates a common race condition with WaitTask, that
happens when predicate function gets resolved right before the execution
context gets destroyed.
This situation results in a "Cannot find context with specified id undefined"
exception.
Credits go to @jakub300 for his wonderful [investigation](https://github.com/GoogleChrome/puppeteer/issues/1325#issuecomment-395472092).
Fixes#1325.
I've been told that this will make our JavaScript tracing 💯x more accurate, at minimal performance loss. Let's turn it on for everyone always.
Fixes#1300.
`Data.prototype.toString` may return non-ASCII characters, which aren't accepted by `setHeader`.
E.g., on Russian locale, it might look like this:
```
> new Date().toString()
'Thu Jun 14 2018 13:11:50 GMT+0300 (Финляндия (лето))'
```
This patch:
- adds `worker.evaluate` and `worker.evaluateHandle` methods as a shortcut to their execution context equivalents.
- makes the error messages a bit nicer when interacting with a closed worker (as opposed to a closed page).
- moves the worker tests into their own spec file.
This patch disables OOPIF by default.
**NOTE**: this is a temporary bandaid for the time we're crafting
the full-fledged support for site isolation over DevTools protocol.

Cirrus CI got some optimizations for containers based of `microsoft/windowsservercore:latest`.
Now startup time for windows builds is around 1:30 seconds instead of around 4 minutes.

It's impossible to launch chromium without initial page.
This patch makes sure that `puppeteer.launch()` always returns a browser
with at least one page user can connect to.
This patch disables crash reporting since it's not needed for
automation purposes.
It also deals some troubles for us since crashpad is a separate
process on Windows which has a larger lifetime than chromium.
This, in turn, prevents us from cleaning up profile directory.
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.
Page subtargets (e.g. out-of-process iframes and others) sometimes
die before we send the 'detach' command.
This is harmless to us, but we shouldn't have an unhandled promise
rejection in this case.
Example crash: https://cirrus-ci.com/task/4884032470908928
This patch drops the markdown-toc module and instead rolls out
our own simple markdown table-of-contents generator.
As a side effect, it fixes links to `page.$` and `page.$$`.
Some of the worker tests were failing on the bots. After investigating, I found one race in the test, and one race upstream in Chromium which I filed upstream as https://crbug.com/846099. But I added a small hack here as a temporary workaround.

This patch allows logging the output of the Chromium process to be enabled in tests by passing in the environment variable `DUMPIO=true`.
Additionally, the `stderr` of the Chromium process will always be logged in the the "Output" section of failing page tests.
Scrollbars look different on different platforms, so must be made invisible in tests. As a drive-by, xdescribe was broken with the new test runner.

Previously protocol.d.ts was generated on `npm run tsc`. This was inconvenient because it meant that vscode checking was wrong until type checking was run manually, and was inefficient because it necessarily regenerated the types even if no new Chromium was downloaded. This patch generates the types when npm install is run from the github checkout, assuming a new Chromium revision was downloaded.
Docs about `page.$$eval` and `frame.$$eval` are not accurate and might be confusing. `document.querySelectorAll` returns `NodeList`, while `frame.$$eval` is actually doing `Array.from(querySelectorAll(selector))`, which actually returns an array.
This makes things this possible:
`await page.$$eval('div', divs => divs.map...)`
This patch fixes docs to mention that $$eval is actually performing:
`Array.from(querySelectorAll(selector))`
Which will let the user understand that the element he receives is an array, and not a NodeList.
