Closing connection for database td.binlog

[MalteToenjes]

Is there a way to close the database td.binlog on purpose?

When I call _self.td_json_client_destroy(self.td_json_client) (I'm using python-telegram), then I get this error:
[ 0][t 0][1572861952.897261381][Client.cpp:272] Check !is_locked failed

For the background:
In some cases I need to restart my API which uses tdlib. But since I can't close the database I cant free up the memory. So I think I have to close the connection to the database first. But I think the tdlib does create the connection, so there should be a way to tell the lib ti close the connection.

This is a sanity check that fires when app tries to destroy a client, which is still used in other thread by td_json_client_receive. You must first stop to use the client and only after that you can call td_json_client_destroy.

The usual way to do that is to call the method close, then wait for updateAuthoriationState with state authorizationStateClosed, stop calling td_json_client_receive and call td_json_client_destroy.

I'm doing it now as you recommended but still get the same error. First I call the method close, then I wait for authorizationStateClosed and when its occured I call _td_json_client_destroy

The error means that td_json_client_receive is called right now for the same client.

Thanks, that was the problem
