Threading issue with addProxy about td

[levlam]

AddProxy will return response after the request will be completed, no matter from which thread it is sent. But the request can't be complited before the TDLib instance is initialized (SetTdlibParameters is called). If the request isn't return, then it is because SetTdlibParameters is never called.

Hi @levlam, thanks a lot for the prompt answer!
It seems that I may not have grasped the correct sequence for utilizing the proxy API.
So what you have to do is initiate the library using SetTdlibParameters call and subsequently incorporate your proxies with AddProxy. Those proxies are kept into the session/cache so if you restart the program they are saved. I guess its clear now.

Just one question, why dont you just raise exception on AddProxy when the lib is not initialized?
That would make it easier to spot the API misusage.

It is better to call AddProxy before SetTdlibParameters. This is supported and intended order of the calls, otherwise you may try to connect without proxy first. But you must not wait synchronously for AddProxy response. Waiting synchronously for request response is a bad idea most of the time.
