By default, TCP connections are created unless ``connection_class`` is specified. Use class:`.UnixDomainSocketConnection` for unix sockets. Any additional keyword arguments are passed to the constructor of ``connection_class``. cKs4t|}d|vr|d|d<|||di|S)a Return a connection pool configured from the given URL. For example:: redis://[[username]:[password]]@localhost:6379/0 rediss://[[username]:[password]]@localhost:6379/0 unix://[username@]/path/to/socket.sock?db=0[&password=password] Three URL schemes are supported: - `redis://` creates a TCP socket connection. See more at: - `rediss://` creates a SSL wrapped TCP socket connection. See more at: - ``unix://``: creates a Unix Domain Socket connection. The username, password, hostname, path and all querystring values are passed through urllib.parse.unquote in order to replace any percent-encoded values with their corresponding characters. There are several ways to specify a database number. The first value found will be used: 1. A ``db`` querystring option, e.g. redis://localhost?db=0 2. If using the redis:// or rediss:// schemes, the path argument of the url, e.g. redis://localhost/0 3. A ``db`` keyword argument to this function. If none of these options are specified, the default db=0 is used. All querystring options are cast to their appropriate Python types. Boolean arguments can be specified with string values "True"/"False" or "Yes"/"No". Values that cannot be properly cast cause a ``ValueError`` to be raised. Once parsed, the querystring arguments and keyword arguments are passed to the ``ConnectionPool``'s class initializer. In the case of conflicting arguments, querystring arguments always win. rNrL)rupdate)clsrry url_optionsrLrLrMfrom_urls )  zConnectionPool.from_urlNr cache_factorycKs|pd}t|tr |dkrtd||_||_||_d|_||_|ds*|drc|ddvr5t d|jd}|durLt|t sHtd ||_n|jdurX|j |_n t |jd |_| dd| ddt|_|dS) Nlrz,"max_connections" must be a positive integer cache_configr1r)rrz4Client caching is only supported with RESP version 3z#Cache must implement CacheInterface)r;rrrconnection_kwargsrr1_cache_factoryrr%r get_cacherpopr6r7 _fork_lockreset)rGrrrrr1rLrLrMrWs6       zConnectionPool.__init__rSc Cs6dt|jdt|jdt|jdi|jdS)NrrrrrL)typerPrOreprrrrfrLrLrMr4szConnectionPool.__repr__cCs|jddS)z Returns: The RESP protocol version, or ``None`` if the protocol is not specified, in which case the server default will be used. rN)rrrfrLrLrMr:szConnectionPool.get_protocolcCs,t|_d|_g|_t|_t|_ dS)Nr) r6r7_lock_created_connections_available_connectionsrO_in_use_connectionsrrrrfrLrLrMrBs  zConnectionPool.resetcCsl|jtkr4|jjdd}|stz|jtkr&|W|jdSW|jdS|jwdS)N)r|)rrrracquirer"rrelease)rGacquiredrLrLrM _checkpidSs# zConnectionPool._checkpid command_namerc Os||j#z|j}Wn ty|}Ynw|j|Wdn1s-wYz7|z| rE|j durIt dWW|SWW|St t fyi| || ret dYW|Swtyv||w)zGet a connection from the poolNConnection has dataConnection not ready)rrrr IndexErrormake_connectionraddrpr}r1r#rrsrrrGrrGoptions connectionrLrLrMget_connections<      zConnectionPool.get_connectioncCs,|j}t|dd|dd|dddS)z,Return an encoder based on encoding settingsrrrrrF)rrr)rrr)rGryrLrLrM get_encoders    zConnectionPool.get_encoderrdcCs\|j|jkr td|jd7_|jdur%t|jdi|j|j|jS|jdi|jS)zCreate a new connectionzToo many connectionsrNrL)rrr#r1r.rrrrfrLrLrMrs  zConnectionPool.make_connectionrc Cs||j;z|j|Wn tyYnw||r&|j|n|jd8_|  WddSWddS1sEwYdS)z(Releases the connection back to the poolrN) rrrrKeyErrorowns_connectionrr@rrsrGrrLrLrMrs   "zConnectionPool.releasecCs |j|jkSrT)rrrLrLrMrrTzConnectionPool.owns_connectionTinuse_connectionscCs`||j|rt|j|j}n|j}|D]}|qWddS1s)wYdS)z Disconnects connections in the pool If ``inuse_connections`` is True, disconnect connections that are current in use, potentially by other threads.

The difference is that, in the event that a client tries to get a connection from the pool when all of connections are in use, rather than raising a :py:class:`~redis.ConnectionError` (as the default :py:class:`~redis.ConnectionPool` implementation does), it makes the client wait ("blocks") for a specified number of seconds until a connection becomes available. Use ``max_connections`` to increase / decrease the pool size:: >>> pool = BlockingConnectionPool(max_connections=10) Use ``timeout`` to tell it either how many seconds to wait for a connection to become available, or to block forever: >>> # Block forever. >>> pool = BlockingConnectionPool(timeout=None) >>> # Raise a ``ConnectionError`` after five seconds if a connection is >>> # not available. >>> pool = BlockingConnectionPool(timeout=5) 2c s(||_||_tjd||d|dS)N)rrrL) queue_classr|rrW)rGrr|rrrrrLrMrWs zBlockingConnectionPool.__init__cCsJ||j|_ z|jdWn tyYnwqg|_t|_dSrT) rrpool put_nowaitr _connectionsrrrrfrLrLrMr#s  zBlockingConnectionPool.resetcCsL|jdurt|jdi|j|j|j}n |jdi|j}|j||S)zMake a fresh connection.NrL)r1r.rrrrr@rrLrLrMr;s  z&BlockingConnectionPool.make_connectionc Os|d}z |jjd|jd}Wn tytdw|dur%|}z.|z |r3tdWW|Stt fyS| ||rOtdYW|Swt y`| |w)a7 Get a connection, blocking for ``self.timeout`` until a connection is available from the pool. If the connection returned is ``None`` then creates a new connection. Because we use a last-in first-out queue, the existing connections (having been returned to the pool after the initial ``None`` values were added) will be returned before ``None`` values. This means we only create new connections when we need to, i.e.: the actual number of connections will only increase in response to demand.
