Disabling auto pong in the client #448

Open gionapaolini opened 3 weeks ago

gionapaolini commented 3 weeks ago

I am using the tungstenite client in some integration tests and I wish to test the case in which the client stop responding to pings. Quoting the documentation:

..For example, upon receiving ping messages tungstenite queues pong replies automatically. The next call to read, write or flush will write & flush the pong reply. This means you should not respond to ping frames manually... ...Note that if read returns a ping, you should flush before passing a custom pong to write, otherwise the automatic queued response to the ping will not be sent as it will be replaced by your custom pong message.

It seems I might be able to overwrite the pong if I do not flush, but is there a way to disable this auto-pong behavior altogether? If not, would it be welcomed as a new feature?

Currently, there is no way to disable this behavior.

As for the feature - I personally don't have any arguments against it as for now - we could have an additional flag in the config to change this behavior so long our defaults are sane and don't make the usage of the library more complicated; also, it should be relatively easy to implement (if we're talking only about auto-pongs; a bit more complex if we want to disable all auto-replies, such as replying to the close frames, etc);

Disabling auto replies effectively means disabling most of the impl WebSocket code. Looks like just using protocol::frame::Frame directly does the trick.
