Description
class Gio.ThreadedSocketService : Gio.SocketService {
parent_instance: GSocketService,
priv: GThreadedSocketServicePrivate*
}A GThreadedSocketService is a simple subclass of GSocketService
that handles incoming connections by creating a worker thread and
dispatching the connection to it by emitting the
[signal@Gio.ThreadedSocketService::run signal] in the new thread.
The signal handler may perform blocking I/O and need not return until the connection is closed.
The service is implemented using a thread pool, so there is a
limited amount of threads available to serve incoming requests.
The service automatically stops the GSocketService from accepting
new connections when all threads are busy.
As with GSocketService, you may connect to
GThreadedSocketService::run, or subclass and override the default handler.
Available since: 2.22
Constructors
g_threaded_socket_service_new
Creates a new GThreadedSocketService with no listeners. Listeners
must be added with one of the GSocketListener “add” methods.
since: 2.22
Instance methods
Methods inherited from GSocketService (3)
g_socket_service_is_active
Check whether the service is active or not. An active service will accept new clients that connect, while a non-active service will let connecting clients queue up until the service is started.
since: 2.22
g_socket_service_start
Restarts the service, i.e. start accepting connections from the added sockets when the mainloop runs. This only needs to be called after the service has been stopped from g_socket_service_stop().
since: 2.22
g_socket_service_stop
Stops the service, i.e. stops accepting connections from the added sockets when the mainloop runs.
since: 2.22
Methods inherited from GSocketListener (12)
g_socket_listener_accept
Blocks waiting for a client to connect to any of the sockets added
to the listener. Returns a GSocketConnection for the socket that was accepted.
since: 2.22
g_socket_listener_accept_async
This is the asynchronous version of g_socket_listener_accept().
since: 2.22
g_socket_listener_accept_finish
Finishes an async accept operation. See g_socket_listener_accept_async()
since: 2.22
g_socket_listener_accept_socket
Blocks waiting for a client to connect to any of the sockets added
to the listener. Returns the GSocket that was accepted.
since: 2.22
g_socket_listener_accept_socket_async
This is the asynchronous version of g_socket_listener_accept_socket().
since: 2.22
g_socket_listener_accept_socket_finish
Finishes an async accept operation. See g_socket_listener_accept_socket_async()
since: 2.22
g_socket_listener_add_address
Creates a socket of type type and protocol protocol, binds
it to address and adds it to the set of sockets we’re accepting
sockets from.
since: 2.22
g_socket_listener_add_any_inet_port
Listens for TCP connections on any available port number for both IPv6 and IPv4 (if each is available).
since: 2.24
g_socket_listener_add_inet_port
Helper function for g_socket_listener_add_address() that
creates a TCP/IP socket listening on IPv4 and IPv6 (if
supported) on the specified port on all interfaces.
since: 2.22
g_socket_listener_add_socket
Adds socket to the set of sockets that we try to accept
new clients from. The socket must be bound to a local
address and listened to.
since: 2.22
g_socket_listener_close
Closes all the sockets in the listener.
since: 2.22
g_socket_listener_set_backlog
Sets the listen backlog on the sockets in the listener. This must be called
before adding any sockets, addresses or ports to the GSocketListener (for
example, by calling g_socket_listener_add_inet_port()) to be effective.
since: 2.22
Properties
Gio.ThreadedSocketService:max-threads
The maximum number of threads handling clients for this service.
since: 2.22
Properties inherited from GSocketService (1)
Properties inherited from GSocketListener (1)
Gio.SocketListener:listen-backlog
The number of outstanding connections in the listen queue.
since: 2.22
Signals
Gio.ThreadedSocketService::run
The ::run signal is emitted in a worker thread in response to an
incoming connection. This thread is dedicated to handling
connection and may perform blocking IO. The signal handler need
not return until the connection is closed.
Signals inherited from GSocketService (1)
GSocketService::incoming
The ::incoming signal is emitted when a new incoming connection
to service needs to be handled. The handler must initiate the
handling of connection, but may not block; in essence,
asynchronous operations must be used.
since: 2.22
Signals inherited from GSocketListener (1)
GSocketListener::event
Emitted when listener‘s activity on socket changes state.
Note that when listener is used to listen on both IPv4 and
IPv6, a separate set of signals will be emitted for each, and
the order they happen in is undefined.
since: 2.46
Signals inherited from GObject (1)
GObject::notify
The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.
