It turned out that almost any usecase requires helper methods to access
DOM inside the ExecutionContext.
Instead of exposing execution contexts as-is, we should introduce
IsolatedWorld as a first-class citizen that will hold execution contexts
inside.
This patch adds a new require, `puppeteer/Errors`, that
holds all the Puppeteer-specific error classes.
Currently, the only custom error class we use is `TimeoutError`. We'll
expand in future with `CrashError` and some others.
Fixes#1694.
This allows us:
- dogfood browser contexts the way we want them to be used
- simplifies the dance around service workers / cookies setting up and tier down.
This changes sendCharacter to use document.execCommand instead of sending a `'char'` event from the protocol. This is more aligned with how input would come in from emoji keyboards, and removes the 3ish byte limit on characters that can be sent which prevented larger emoji from being rendered correctly.
Emoji will still fail to type correctly if typing them into an iframe that is in shadow dom.
fixes#1096
This patch rolls Chromium to r579032. The patch includes:
- https://crrev.com/577366 - DevTools: report redirect responses only if response interception is enabled
- https://crrev.com/577212 - DevTools: intercept requests resulting from redirects
- https://crrev.com/578934 - DevTools: Add a protocol method to insertText
Interception Logic in DevTools protocol has changed regarding redirects;
this patch migrates interceptions to dispatch "request" events based on
requestWillBeSent event.
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.
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
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
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.
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 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.
`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.

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.
