In the remove_intercept method, when removing all intercepts, modifying the list while iterating over it can cause issues. Consider using a copy of the list for iteration.
for intercept_id in self.intercepts: # remove all intercepts
self.conn.execute(self.command_builder("network.removeIntercept", {"intercept": intercept_id}))
self.intercepts.remove(intercept_id)
When removing a request handler, the code calls session.subscribe instead of session.unsubscribe, which would keep the subscription active instead of removing it.
The _on_request callback function doesn't handle all possible parameters from the event data, potentially missing important request information like method and headers.
✅ Fix incorrect event unsubscriptionSuggestion Impact:The commit implemented the exact change suggested, replacing session.subscribe with session.unsubscribe when unsubscribing from events with no remaining callbacks
When unsubscribing from an event with no remaining callbacks, you should use session.unsubscribe instead of session.subscribe. The current implementation incorrectly resubscribes to events when trying to unsubscribe.

Why: The code incorrectly calls "session.subscribe" when trying to unsubscribe from events with no remaining callbacks. This is a critical bug that would cause the opposite of the intended behavior, keeping subscriptions active instead of removing them.

Add null validation for required parameters before accessing their attributes to prevent potential NoneType errors

General
✅ Remove inconsistent subscription handling to prevent potential state issuesSuggestion Impact:The commit implemented a more comprehensive solution by completely refactoring the subscription handling logic. Instead of just uncommenting the session_subscribe line, it created a new implementation where both subscribe and unsubscribe are properly handled in the new code structure.

+ params["events"] = [event_name]
+ self.conn.execute(self.command_builder("session.subscribe", params))

+ except KeyError:
+ raise Exception(f"Event {event} not found")

+ params = {}
+ params["events"] = [event_name]
+ self.conn.execute(self.command_builder("session.subscribe", params))
+ del self.subscriptions[event_name]
The session_subscribe call is commented out but the session_unsubscribe is still active, which could lead to inconsistent subscription state - either uncomment the subscribe call or remove both.
Why: The inconsistency between commented subscribe and active unsubscribe calls could lead to subscription state issues. This needs to be resolved to ensure proper event handling.

I'm not a Python expert but I ended up being the person who drafted the initial BiDi implementation. I tried to avoid using the async/await pattern because I assumed that it can't be used in a sync code that the majority of Python clients of the library do. Is there any reason to use the pattern in this PR?
It has pros and cons, but I think you're right that it isn't needed and could be more trouble than it's worth. I'll remove it for the time being and if we decide later it's an easy shift.
Can we add some high-level API examples and tests per an original issue?
driver.network.add_request_handler(...)
driver.network.add_response_handler(...)
This would allow us to surface the API usage and make sure it works nicely via lambdas.
Could you provide a bit more guidance here? What would those two tests entail that isn't already being covered? the tests I added are an expanded version of the .spec from the ruby implementation
I think the current tests expose the low-level API that users are not supposed to call. The high-level API unfortunately is not implemented in any bindings so there is no example to follow. However, the proposal is to allow the add_request_handler to accept a matcher (e.g. URL filter for what requests should be handled) and a callback that received the request to handle. This callable is responsible for continuing/failing the request optionally allowing to mutate it (e.g. add headers).

Much closer to what we are aiming for! Let's add some abstractions (Request/Response) objects, move continuation there, and write more tests. I've left more detailed comments in the PR review.
Not quite, we need to make Request/Response be passed to the callbacks instead of plain event, see https://github.com/SeleniumHQ/selenium/pull/14592#issuecomment-2477187410 for the example.

def callback_on_url_match(data):
if url_pattern in data['request']['url']:
callback(data)
it should create a request/response object, then perform the callback on that object instead of on the event itself.
3. The response and request classes should just be simple objects with the continue method (and mark continue public). e.g.
class Request:
def __init__(self, request_id, url, method, headers, body, network: Network):
self.request_id = request_id
self.url = url
self.method = method
self.headers = headers
self.body = body
self.network = network
def continue_request(self):
"""Continue after sending a request."""
params = {
'requestId': self.request_id
}
if self.url is not None:
params['url'] = url
if self.method is not None:
params['method'] = method
if self.headers is not None:
params['headers'] = headers
if self.postData is not None:
params['postData'] = postData
self.network.conn.execute('network.continueRequest', params)
Current status: Only 1 test is currently passing (test_network_initialized()), however the browser now recognizes commands as legitimate seemingly. I am not sure why callbacks are not being called, as the returned request_ids from add_request/response_handler() are Null
Possible causes:
race-conditions (should we make implementation async again?)
incorrect implementation of add_intercept (could be why auth handler is not working in pages.load(basicAuth))
@shbenzer You might need to add some waits to give the time for the callback to be called. Start by adding sleep(5) and see if it stabilizes the test. If yes, you can figure out a better waiting strategy. If no, there is probably something wrong with the implementation itself.
@shbenzer Any chance you could take a look at https://github.com/SeleniumHQ/selenium/pull/14900? The implementation @aguspe made works and you can follow it to make the Python bindings part.
Oh sorry @shbenzer I think I got your notification lost and I marked everything as read :)
I can give it a deeper look over the weekend, but maybe the issue is here:
def __on(self, event, callback): """Set a callback function to subscribe to a network event.""" event = self.EVENTS.get(event, event) self.callbacks[event] = callback if len(self.subscriptions[event]) == 0: session_subscribe(self.conn, event, self.__handle_event)
The part that confused me the most was not how to add a callback, but also to have the listener listening for the event, it looks right but maybe you can print out to the console the responses and the requests
I noticed a couple of errors while I was implementing it, and by debugging it that way I noticed that I was using the listener wrongly :)
Haven't had a ton of time lately, but should hopefully be able to take a good look over the next two weeks. I'm currently getting this error when trying to test though

@aguspe and @p0deje So I finally got bazel working again, and have a few thoughts on the implementation:
Bear in mind I wrote this pr 2 months ago now lol, so I'm trying to get back into this.
I don't like the command iterator. I added it because just doing self.conn.execute(command) wasn't working because it was requiring an iterator to execute. script.py uses self.conn.execute(session_subscribe(LogEntryAdded.event_class)), can we utilize session_subscribe like this for network? execute() takes in a command and serializes it itself, so I'm not sure if session_subscribe() will accomplish what we need. but maybe add_callback() would (see 2)
the ruby bindings use the add_callback() function from the bidi object, the equivalent in python is self.conn.add_callback() and it's used by script.py. Do we think we can shift to use that instead? Also, do we think we should be storing the callbacks inside the network object instead of using that functionality in the conn object? (or evend do both?)
The problems occur/tests fail in the communication with the bidi connection - it's not able to add, remove, continue intercepts/auth. The only thing performing correctly is the establishment of the connection. I think the communication/command problems would either be fixed or made easier to solve by points 1 and 2.
