9498b1057b fix(helpers): support thrown strings and numbers in getExceptionMessage (#2715)
Of course, strings aren't proper errors, but scripts sometimes do that, and Puppeteer loses such error messages.

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.

8c54f41552 chore(types): generate a d.ts file for protocol types (#2325)
This uses the `/json/protocol` endpoint to generate type definitions for the protocol.

Currently it is lacking protocol events and commands, but I will add those later.

2370618819 chore(types): upgrade to TypeScript 2.8.1 (#2304)

feat: Introduce BrowserFetcher class (#1983)
This patch introduces `BrowserFetcher` class that manages
downloaded versions of products.

This patch:
- shapes Downloader API to be minimal yet usable for our needs. This
  includes removing such methods as `Downloader.supportedPlatforms` and
  `Downloader.defaultRevision`.
- makes most of the fs-related methods in Downloader async. The only
  exception is the `Downloader.revisionInfo`: it has stay sync due to the
  `pptr.executablePath()` method being sync.
- updates `install.js` and `utils/check_availability.js` to use new API
- finally, renames `Downloader` into `BrowserFetcher`

Fixes #1748.

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.

a71f287c6b Fix evaluation in case of first "undefind" argument (#732)
It turns out that [undefined, 1].join(',') results in ",1" instead
of "undefined,1". This causes a syntax error when trying to pass undefined
as a first argument to `page.evaluate` method.

Fixes #572.

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.

20ba447689 [DEBUG] Trace only those events which have listeners. (#201)
The `DEBUG=*page npm run unit` is too verbose due to events spamming
the console.

listeners.

ff5ed1c738 Implement page.waitForFunction method
The page.waitForFunction method allows to wait for a general predicate.
The predicate will be continiously polled for in page, until
it either returns true or the timeout happens.

The polling parameter could be one of the following:
- 'raf' - to poll on every animation frame
- 'mutation' - to poll on every dom mutation
- <number> - to poll every X milliseconds

bbde8fd1c2 page.evaluate takes a string in addition to function (#135)
This patch improves on page.evaluate to accept a string.
The string can have a trailing '//# sourceURL=' comment which would
name the evaluation to make stacks beautiful.

In order to make sourceURL comments possible, this patch:
- removes wrapping of the client function into `Promise.resolve()`
- stops passing `awaitPromise` parameter to `Runtime.evaluate`
- starts to await promise via the `Runtime.awaitPromise` if the return type of the evaluation
  is promise

closes #118
