Issue #8832 makes a good point that we should not be making
implicit assumptions about the client's performance
when waiting for internal events. At the same time,
we want to be able to get the debug info if some promises
never resolve because of missing backend events.
This PR adds a variable to turn on timeouts for deferred
promises created using `createDebuggableDeferredPromise`.
We can use it in our tests to catch never-resolving
promises or when reproducing bug reports where Puppeteer
hangs indefinitely.
Closes#8832
There is no repro but it looks like sometimes the backend reports
two navigation requests. This PR changes the logic to allow that
instead of failing as it seems that failing is a bigger issue
than handling multiple navigation requests.
Closes#8811
Two main sources of flakiness addressed:
1) we should dispose the lifecycle watcher after we waited for the navigation response (bad API? we need to refactor but I think it'd be valuable to stabilize tests first without too many changes).
2) we should wait for the navigation request's response if there is a navigation request in the watcher.
Closes#8644
Previously, if timeout is falsy, the targets would only
be checked if a browser-level event fires which lead to
a race: if the events arrived before waiting for a target,
the promise would never resolve.
Fixes#8763
This PR implements automatic detection of the Firefox product when the `.connect()` method is used. This partially undoes the breaking change in https://github.com/puppeteer/puppeteer/pull/8520 but it's also a breaking change on its own since we don't accept an explicit product name anymore (it does not look like it was used anyway).
When we attach to a frame, we send a call to get
the page frame tree from CDP. Based on the tree data
we look up the parent frame if parentId is provided.
The problem is that the call to get the page frame
tree could take arbitrary time and the calls for the
parent and child frames might happen at the same time.
So the situation where the frame tree for the child frame
is resolved before the parent frame is known is fairly
common.
This PR addresses the issue by awaiting for the parent
frame id before attempting to register a child frame.
* feat: use CDP's auto-attach mechanism
In this PR, we refactor Puppeteer to make use of the CDP's auto-attach mechanism. This allows the backend to pause
new targets and give Puppeteer a chance to configure them properly. This fixes the flakiness related to dealing with
OOPIFs and should fix some other issues related to the network interception and navigations. If those are not fixed completely by this PR, the PR serves a solid base for fixing them.

BREAKING CHANGE: With Chromium, Puppeteer will now attach to page/iframe targets immediately to allow reliable configuration of targets.
