c5fe1dbdbb chore(tests): redirect debugError to the output category of tests (#2969)
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.

ed7a26cc95 feat(tracing): enable high resolution JavaScript sampling (#2702)
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.

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.

ff08e45785 fix: Remove synchronous operation with file system. (#879)
This patch:
- introduces `helper.promisify` - a simple polyfill for the `util.promisify`. The 
  `util.promisify` could not be used due to Node6 compatibility issues.
- migrates all sync filesystem operations to the async replicas

Fixes #884.

e59172de83 chore: Use Typescript to lint JSDoc annotations (#986)
This patch starts using typescript to lint JSDoc annotations.

Note: this uses typescript's bleeding edge. We should migrate to stable once
it has all the necessary bugfixes.

0bea42bd8c Do not leave dangling promises when sending messages over protocol (#742)
It's very bad to have 'unhandled promise rejection' that can't be
handled in user code. These errors will exit node process in a near
future.

This patch avoids 'unhandled promise rejection' while sending protocol
messages.

This patch:
- introduces `puppeteer:error` debug scope and starts using it for all
  swalloed errors.
- makes sure that every `client.send` method is either awaited or its
  errors are handled.
- starts return promises from Request.continue() and Request.abort().
- starts swallow errors from Request.contine() and Request.abort().

The last is the most important part of the patch. Since
`Request.continue()` might try to continue canceled request, we should
disregard the error.

Fixes #627.

fe06c896eb Roll chromium to 492629 (#230)
This patch
- rolls chromium to 492629
- migrates connection establishing to use browser target. This migration means
  that now we have a single websocket connection to browser (implemented
  in Connection class). A connection to a particular target is
  incapsulated in a new Session class.
