Unfortunately, disabling javascript in page prevents any microtasks
to be executed even from puppeteer-originating javascript. As a
result, the IntersectionObserver hack we use to conditionally
scroll into view doesn't work.
To workaround this, we start always scrolling before clicking if
page's javascript is disabled.
Fixes#2898

- https://crrev.com/574785 - DevTools: allow tracing over the remote debugging pipe.
This fixes tracing over the remote debugging pipe.
Chrome DevTools shows anonymous scripts with yellow background and names
them with `debugger://VM<scriptId>` prefix.
This patch starts reporting the same debugger:// urls for anonymous
scripts in puppeteer's JS coverage. This might simplify debugging, e.g.
using `debugger;` statement to reveal the script in DevTools and later
matching it against the one in the coverage.
This patch:
- simplifies test reusing the `offscreenbuttons.html` asset
- aligns IntersectionObserver usage with the one we have for
`ElementHandle._scrollIntoViewIfNeeded`.
This patch adds `reportAnonymousScripts` option to the `coverage.startJSCoverage` method. With this option, anonymous scripts are reported as well.
Fixes#2777
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.

Fixes#1325.
