When an evaluation causes a navigation, for example:
```js
await page.evaluate(() => window.reload());
```
sometimes we process the ExecutionContextDestroyed event before the ack from the evaluate. When we do get the ack from the evaluate, we try to build a JSHandle for it, and try to find the execution by id. But it is gone, and we throw an error. This patch switches createJSHandle to accept an ExecutionContext instead of just an id.
This bug was making the test `should throw a nice error after a navigation` flaky.
In accordance with its declared type, `Map<string, Function>`.
Currently, it is used as a plain old JS object. The compiler marks this
usage as an error when `noImplicitAny: true`. This change switches to
use the appropriate Map methods `has/get/set`.
Fixes#3000
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.
When process is spawned with the 'pipe' set for stdout and stderr, Node expects these streams to be actually dispatched. If we don't, write into pipe becomes blocking and chrome stalls.
We work around that via setting 'ignore' to the stdin, stdout and stderr when the pipe communication channel is used.
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.
Today, `page.close()` method doesn't run page's beforeunload listeners.
This way users can be sure that `page.close()` actually closes the
page.
This patch adds an optional `runBeforeUnload` option to the
`page.close()` method that would run beforeunload listeners. Note:
running beforeunload handlers might cancel page closing.
Fixes#2386.
This patch teaches Page.waitForNavigation to correctly handle navigation
to pages that have frames that might never load.
These frames include:
- frames which main resource loading was aborted due to mixed-content
error
- frames that artificially called `window.stop()` to interrupt loading
themselves
Fixes#1936.
This patch fixes puppeteer navigation primitives to work with
same-document navigation.
Same-document navigation happens when document's URL is changed,
but document instance is not re-created. Some common scenarios
for same-document navigation are:
- History API
- anchor navigation
With this patch:
- pptr starts dispatching `framenavigated` event when frame's URL gets
changed due to same-document navigation
- `page.waitForNavigation` now works with same-document navigation
- `page.goBack()` and `page.goForward()` are handled correctly.
Fixes#257.
In certain cases, all callbacks could be rejected before we get a
response from transport. This is easily reproducible with `slowMo`
option.
Fixes#563.
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.
This patch introduces a new `pipe` option to the launcher to connect over a pipe.
In certain environments, exposing web socket for remote debugging is a security risk.
Pipe connection eliminates this risk.
This patch adds support for `timeout: 0` to disable timeout for the following functions:
- `page.waitForFunction`
- `page.waitForXPath`
- `page.waitForSelector`
and their `frame` counterparts.
Fixes#2200
This patch:
- starts fulfilling security details for redirect responses
- changes `response.securityDetails()` to return null if the response
is served over non-secure connection
This patch introduces ExecutionContext.frame() that returns Frame
associated with this Execution Context.
This allows to associate console messages with the originating frame,
if any.
This patch:
- introduces `SecurityDetails` class that exposes a set of fields that describe properties of secure connection
- introduces method `response.securityDetails()` that returns an instance of `SecurityDetails` object.
keyboard.down() and keyboard.up() both use the _pressedKeys Set, however keyboard.down() adds and searches for the key code, whereas keyboard.up() attempts to delete based on the key rather than the key code.
Fixes#1901
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.
This patch:
- introduces `test/assets/cached` folder and teaches server to cache
all the assets from the folder
- introduces `test/assets/serviceworkers` folder that stores all the
service workers and makes them register with unique URL prefix
- introduces `Response.fromCache()` and `Response.fromServiceWorker()`
methods
Fixes#1551.
This PR fixes lost functionality that is no longer on-par with the documentation for `Page.select`, namely:
> `...values` <...string> Values of options to select. If the `<select>` has the `multiple` attribute, all values are considered, **otherwise only the first one is taken into account**.
I've also added an accompanying test for this use case.
This patch:
- migrates CI to use NPM
- drops lockfiles (`yarn.lock`). Lockfiles are ignored by package
managers when the package is installed as a dependency, so this makes CI closer to the
installation our clients run.
This patch introduces a `slowMo` option to the `puppeteer.connect` method. The option
is similar to the one in `puppeteer.launch` and is used to slow down the connection.
This patch:
- introduces `page.waitForXPath` method
- introduces `frame.waitForXPath` method
- amends `page.waitFor` to treat strings that start with `//` as xpath queries.
Fixes#1757.
feat: expose raw devtools protocol connection
This patch introduces `target.createCDPSession` method that
allows directly communicating with the target over the
Chrome DevTools Protocol.
Fixes#31.
Since interception events and `loadingFailed` events come from
different processes and are not serialized, we might get `loadingFailed` event and a subsequent outdated `requestIntercepted`.
Short-term, this patch stops assuming that interception events are
aligned with `loadingFailed`.
Long-term, this will be resolved as @caseq completes network
servicification effort in chromium.
Fixes#880.
If the success value of `waitForFunction` was not serializable, checking whether it was truthy with `.jsonValue()` might fail. Now I check whether it was truthy inside the page.
Fixes#1737.
This patch:
- teaches page.waitFor* methods to accept JSHandles
- starts returning JSHandles from page.waitFor* calls.
BREAKING CHANGE: this patch starts allocating `JSHandle`/`ElementHandle` instances for every call to `page.waitFor*` functions. These handles should be disposed manually to avoid memory consumption.
Fixes#1703, fixes#1654, fixes#1724.
This patch adds two new methods to the `page.coverage` namespace:
- `page.coverage.startCSSCoverage()` - to initiate css coverage
- `page.coverage.stopCSSCoverage()` - to stop css coverage
The coverage format is consistent with the JavaScript coverage.
This patch introduces a new `page.coverage` namespace with two methods:
- `page.coverage.startJSCoverage` to initiate JavaScript coverage
recording
- `page.coverage.stopJSCoverage` to stop JavaScript coverage and get
results
This patch:
- adds `puppeteer.defaultArgs()` method to get default arguments that are used to launch chrome
- adds `ignoreDefaultArgs` option to `puppeteer.launch` to avoid using default puppeteer arguments
Fixes#872
The patch converts all the getters in the codebase into the methods.
For example, the `request.url` getter becomes the `request.url()`
method.
This is done in order to unify the API and make it more predictable.
The general rule for all further changes would be:
- there are no getters/fields exposed in the api
- the only exceptions are "namespaces", e.g. `page.keyboard`
Fixes#280.
BREAKING CHANGE:
This patch ditches getters and replaces them with methods throughout
the API. The following methods were added instead of the fields:
- dialog.type()
- consoleMessage.args()
- consoleMessage.text()
- consoleMessage.type()
- request.headers()
- request.method()
- request.postData()
- request.resourceType()
- request.url()
- response.headers()
- response.ok()
- response.status()
- response.url()
