Constructor & Destructor Documentation

◆ fuh()

fuh::fuh ( const config & c )

Reads wesnothd's config for the data needed to initialize this class and dbconn.

		int	player_id,
		int	offset,
		std::string &	search_game_name,
		int	search_content_type,
		std::string &	search_content
	)

virtual

Runs an asynchronous query to fetch the user's game history data.

The result is then posted back to the main boost::asio thread to be sent to the requesting player.

Parameters

io_service	The boost io_service to use to post the query results back to the main boost::asio thread.
s	The server instance the player is connected to.
socket	The socket used to communicate with the player's client.

Implements user_handler.

◆ async_test_query()

void fuh::async_test_query	(	boost::asio::io_context &	io_service,
		int	limit
	)

virtual

A simple test query for running a query asynchronously.

The main point is that it takes a meaningful amount of time to complete so that it's easy to see that multiple are running at once and are finishing out of order.

Parameters

io_service	The boost io_service to use to post the query results back to the main boost::asio thread.
limit	How many recursions to make in the query.

Implements user_handler.

However, they are basically never used on forums.wesnoth.org, so this shouldn't be a problem.

Implements user_handler.

◆ user_is_moderator()

bool fuh::user_is_moderator ( const std::string & name )

virtual

Parameters
