In case of multiple sessions to the same target, there's a race between
sessions to create a secondary isolated world. As a result, we might
end up having 2 execution contexts created for the needs of the
secondary isolated world.
This patch starts handling this race gracefully: instead of crashing,
we can use either of the execution contexts and ignore the rest.
Notably, the same race condition might happen if page reloads itself
in-between the calls to `page.addEvaluateOnNewDocument` and
`page.createIsolatedWorld`.
Fixes#4197.
This patch:
- refactors `NetworkManager`/`FrameManager` so that they enable all the
relevant domains themselves. This is a preparation for OOPIF support and
migration onto fetch domain.
- moves `networkManager` ownership into `FrameManager`. This way it's clear who owns what.
- stops enabling Security domain: it saves quite some traffic over
websocket since it no longer sends annoying "SecurityStateChanged" events.
Instead, use `Security.setIgnoreCertificateErrors` method.
- consolidates network cache state in network manager. This even fixes a
bug with caching and request interception interop.
Method `page.setDefaultTimeout` overrides default 30 seconds timeout
for all `page.waitFor*` methods, including navigation and waiting
for selectors.
Fix#3319.
This patch starts executing frame.waitForSelector and frame.waitForXPath
in secondary world. As a result, websites that mutate page global
context (e.g. removing global MutationObserver) don't break Puppeteer's
behavior.
Fixes#609
`page.waitForSelector` should return `null` if waiting for `hidden:
true` and there's no matching node in DOM.
Before this patch, `page.waitForSelector` would return some JSHandle
pointing to boolean value.
Introduce `//lib/api.js` that declares a list of publicly exposed
classes.
The `//lib/api.js` list superceedes dynamic `helper.tracePublicAPI()` calls
and is used in the following places:
- [ASYNC STACKS]: generate "async stacks" for publicy exposed API in `//index.js`
- [COVERAGE]: move coverage support from `//lib/helper` to `//test/utils`
- [DOCLINT]: get rid of 'exluded classes' hardcoded list
This will help us to re-use our coverage and doclint infrastructure
for Puppeteer-Firefox.
Drive-By: it turns out we didn't run coverage for `SecurityDetails`
class, so we lack coverage for a few methods there. These are excluded
for now, sanity tests will be added in a follow-up.
This patch splits out `IsolatedWorld` class from Frame.
The `IsolatedWorld` abstraction is an execution context
with a designated set of DOM wrappers.

This patch teaches `page.setContent` to await resources in
the new document.
**NOTE**: This patch changes behavior: currently, `page.setContent`
awaits the `"domcontentloaded"` event; with this patch, we can now await
other lifecycle events, and switched default to the `"load"` event.
The change is justified since current behavior made `page.setContent`
unusable for its main designated usecases, pushing our client
to use [dataURL workaround](https://github.com/GoogleChrome/puppeteer/issues/728#issuecomment-334301491).
Fixes#728
NavigatorWatcher subscribes to Connection to get a `Disconnected` event,
causing us to hit the default max of 10 listeners constraint.
Technically we don't leak anything here and can safely bump
the maxListenersCount to Infinity.
However, we conveniently have `CDPSession`, and
can re-dispatch the event on it and keep the safety check in place.
This upgrades us to TypeScript 3.1.1, which fixes some build failures. Annoyingly TypeScript does a better job of checking `process.stdio`, which exposes that the DefinitelyTyped definition for it is wrong. See https://github.com/DefinitelyTyped/DefinitelyTyped/issues/11587. I'll look into submitting a patch for that later.
This patch introduces API to manage frame navigations.
As a drive-by, the `response.frame()` method is added as a shortcut
for `response.request().frame()`.
Fixes#2918.
This patch:
- moves implementation of page.goto and page.waitForNavigation
into FrameManager. The defaultNavigationTimeout gets moved to
FrameManager as well.
- moves NavigatorWatcher into FrameManager to avoid circular dependency
References #2918
I ran TypeScript against our code with `strictNullChecks` on. Most of the errors generated are noise, because TypeScript doesn't understand how our `assert` method works. But some were legitimate bugs. They are fixed in this patch.
This patch:
- merges `ElementHandle` into `ExecutionContext` (for simplicity; there's no good reason to have them in separate files).
- removes the necessity to pass handle factory when creating `ExecutionContext`
This makes it easier to create execution contexts out of payloads.
References #1215
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.
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.
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.
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.
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 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.
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 adds support for `timeout: 0` to disable timeout for the following functions:
- `page.waitForFunction`
- `page.waitForXPath`
- `page.waitForSelector`
and their `frame` counterparts.
Fixes#2200
