- fix#6340
- Exposes all the network related events (request, response, requestfailed, requestfinished) through the browser context to allow for managing network activity even if the is any navigations through popups or to new tabs which could result in creation of multiple page objects.
There are a few ways for `connect()` to finish:
- `Browser.close()` from the client side.
- Browser on the server side did exit (e.g. crashed).
- Connection was dropped by either of the sides.
We reduce all the cases to the last one by dropping the
connection when client wants calls `Browser.close()` or
server-side browser exits.
In all these cases we should properly cleanup on the server side,
and ensure that all promises reject on the client side.
We await the predicate now. For synchronous predicates,
nothing should change becase the await will finish before
the next protocol message arrives (thanks to `makeWaitForNextTask`).
This changes the root object from RemoteBrowser to Playwright,
similar to local driver connection. This way, any remote connection
gets a Playwright object.
This also starts reusing PlaywrightServer class, and introduces
`cli run-server` hidden command that runs ws server on the
specified port.
Previous structure:
```
RemoteBrowser
- browser (using ConnectedBrowser for remote-specific behavior)
- selectors (special instance for this remote connection)
```
New structure:
```
Playwright
- ...
- selectors (special instance for this remote connection)
- preLaunchedBrowser (using ConnectedBrowser for remote-specific behavior)
```
This makes it much nicer to use `BrowserType` because it no longer has a template.
Technically a breaking change because of the rare edge case where someone used their own non-browser type inside the template, but I don't consider that intended behavior and think this is fine.
These methods are safe to call while the page is still open, or when it is
already closed. Works in remotely connected browser as well.
Also makes video.path() to throw for remotely connected browser.
Under the hood migrated Download and Video to use the common Artifact object.
