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()
This patch unifies node6 transpilation:
- instead of generating multiple top-level directories, prefixed with
`node6-`, all transpiled code gets placed under single `node6/` folder
- transpilation doesn't change require paths of transpiled modules any
more
This patch:
- renames ChromiumDownloader into just Downloader (this is in
preparation for different products download)
- moves Downloader from utils/ to lib/. This unifies all of the
production-critical code in the lib/.
Drive-by: make Downloader a regular class.
This refactors the page.content and page.setContent methods to be defined on the Frame class. This allows access from the Page still but also on all frames.
Fixes#754
Since non-promise values always win the `Promise.race`, we shouldn't
return `null` for timeout promise in NavigationWatcher.
Instead, we can return a promise that never resolved. It should be
GC'd later with the navigation watcher itself.
Fixes#1417.
With the addition of `browser.targets()` api, we now can connect to
in-flight targets.
For Puppeteer, it means that it can "miss" certain events happenning
while it wasn't attached to the target.
This patch:
- fixes this problem with NetworkManager, preparing it for the
missed `requestWillBeSent` event.
- adds a new test to ensure that not a single unhandled promise
rejection has happened during test execution.
Fixes#1363.
Currently, the NavigatorWatcher ensures that all the frames in the
frame subtree reach the desired lifecycle events state.
For this to be fully correct, NavigatorWatcher should also check
navigation status whenever frames are detached.
In Blink, frames don't necesserily have execution context all the time.
DevTools Protocol precisely reports this situation, which results in
Puppeteer's frame.executionContext() being null occasionally.
However, from puppeteer point of view every frame will have at least a
default executions context, sooner or later:
- frame's execution context might be created naturally to run frame's
javascript
- if frame has no javascript, devtools protocol will issue execution
context creation
This patch builds up on this assumption and makes frame.executionContext()
to be a promise.
As a result, all the evaluations await for the execution context to be created first.
Fixes#827, #1325
BREAKING CHANGE: this patch changes frame.executionContext() method to return a promise.
To migrate onto a new behavior, await the context first before using it.
The SIGHUP signal is sent whenever the controlling terminal is closed.
On Windows, SIGHUP is emulated by libuv, and will be the only signal we
receive before the application will be terminated.
This patch starts handling SIGHUP in the same way we handle SIGTERM.
Fixes#1367.
SIGTERM signal is widely used to notify application that it will be shut down.
This patch starts listening to SIGTERM event to gracefully retire
chromium instance.
References #1047.
Currently, `elementHandle.screenshot` passes bounding box into the `page.captureScreenshot`
method.
This is wrong since `captureScreenshot` accepts viewport, not bounding box.
This patch uses layout metrics to convert bounding box into viewport.
Fixes#1315.
Currently, we wait only for the main frame to reach the desired
lifecycle state.
This patch starts waiting until all the frames reach the desired
lifecycle state.
Fixes#1173.
This patch:
- starts persisting lifecycle state for every frame
- migrates NavigationWatcher to rely on these lifecycle events
- refactors Page.goto to properly return navigation errors
Fixes#1218.
This patch starts asserting that all values are of type "string".
The alternative approach to cast values to strings
might yield a hard-to-debug errors.
Fixes#1276.
This roll brings in a bunch of important patches:
- crrev.com/512647 Changed headless browser profile dir to use Default profile path
- crrev.com/512760 DevTools: stop idleness detector when pending navigation commits
- crrev.com/512905 DevTools: introduce Page.getFrameTree
- crrev.com/513373 DevTools: report loaderId in the lifecycle events
- crrev.com/513419 DevTools: introduce Page.setLifecycleEventsEnabled
- crrev.com/513422 DevTools: return loaderId from Page.navigate
Fixes#921
BREAKING CHANGE:
Headless user profile structure is changing. Custom profiles set with --user-data-dir flag will no longer be read in Chrome 63 and will have to be recreated.
Alternatively, you can migrate old headless profile to a new structure. if you stored your profile in `<profile>` folder, you would run the following bash commands:
```bash
cd <profile>
mkdir Default
mv * Default
```

This patch adds `Frame.select` method that does the same functionality as
former `Page.select`, but on a per-frame level.
The `Page.select` method becomes a shortcut for the ÷main frame's select.
Fixes#1139
This patch migrates puppeteer to support PlzNavigate chromium
project.
As a consequence of this patch, we no longer wait for both
requestWillBeSent and requestIntercepted events to happen. This should
resolve a ton of request interception bugs that "hanged" the loading.
Fixes#877.
Currently, NavigationWatcher listens to lifecycle events from Page
domain and security events from Security domain.
However, the events are dispatched from different processes in browser:
- Page's lifecycle events are dispatched from renderer process
- Security events are dispatched from browser process
This makes for the undefined order between events and results in
NavigationWatcher reporting different failuer messages, based on
the event order.
This patch stops relying on security errors in navigation watcher and
instead switches to request failure codes for the main resource.
Fixes#1195
