Chrome Headless used to open about:blank by default; however, this
was recently changed.
We should open starting page no matter what to keep the environment
predictable.
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
This roll includes:
- 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
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.
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.
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.
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.
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.
Page subtargets (e.g. out-of-process iframes and others) sometimes
die before we send the 'detach' command.
This is harmless to us, but we shouldn't have an unhandled promise
rejection in this case.
Example crash: https://cirrus-ci.com/task/4884032470908928
Some of the worker tests were failing on the bots. After investigating, I found one race in the test, and one race upstream in Chromium which I filed upstream as https://crbug.com/846099. But I added a small hack here as a temporary workaround.
References #2632
This adds `page.workers()`, and two events `workercreated` and `workerdestroyed`. It also forwards logs from a worker into the page `console` event.
Only dedicated workers are supported for now, ServiceWorkers will probably work differently because they aren't necessarily associated with a single page.
Fixes#2350.
This patch starts explicitly passing allowed options to the `Browser`
class. This, for example, makes it impossible to pass `appMode` as
an option to the `pptr.connect`.
This patch introduces Browser Contexts and methods to manage them:
- `browser.createIncognitoBrowserContext()` - to create new incognito
context
- `browser.browserContext()` - to get all existing contexts
- `browserContext.dispose()` - to dispose incognito context.
Fixes#85.
