Adds guidance for producing accurate colors in PDF output. page.pdf() can produce unexpected document colors unless forced to render exact colors.
Fixes#2685
EmualationManager used to be injecting touch hooks to properly
support touch emulation.
However, these are no longer necessary, since https://crbug.com/133915
is long fixed.
Originally, we use `Element.scrollIntoViewIfNeeded` to make sure
button is on screen before trying to click it.
However, `Element.scrollIntoViewIfNeeded` doesn't work in certain
scenarios, e.g. when element is partially visible and horizontal
scrolling is required to make it fully visible.
This patch polyfills `element.scrollIntoViewIfNeeded` using
IntersectionObserver and `Element.scrollIntoView`.
Fixes#2804.
Cirrus CI recently started supporting Mac OS builds. This PR adds a CI task to test Puppeteer on MacOS.
It uses Node 8 since only [Node 6 and Node 8 are LTS](https://github.com/nodejs/Release#release-schedule) so `brew` only has receipts for those two TLS versions besides the latest one.
This roll includes:
- https://crrev.com/567104 - DevTools: introduce Target.exposeDevToolsProtocol() method
The patch includes a drive-by fix to DevToolsAgentHostImpl that
eliminats chromium crashes in certain cases.
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.
