* PING/PONG health checksAndy McCurdy2019-07-265-28/+275
| | | | | | | | | | | | | | | | | | | | | | The `Redis` class and the `ConnectionPool` class now support the "health_check_interval=N" option. By default N=0, which turns off health checks. `N` should be an integer, and when greater than 0, ensures that a health check is performed just before command execution anytime the underlying connection has been idle for more than N seconds. A health check is a full PING/PONG round trip to the Redis server. If a health check encounters a ConnectionError or TimeoutError, the connection is disconnected and reconnected and the health check is retried exactly once. Any error during the retry is raised to the caller. Health check retries are not governed by any other options such as `retry_on_timeout`. In systems where idle times are common, these health checks are the intended way to reconnect to the Redis server without harming any user data. When this option is enabled for PubSub connections, calling `get_message()` or `listen()` will send a health check anytime a message has not been read on the PubSub connection for `health_check_interval` seconds. Users should call `get_message()` or `listen()` at least every `health_check_interval` seconds in order to keep the connection open.
* Ability to create a client that uses a single connectionAndy McCurdy2019-07-235-56/+110
| | | | | | | | | | | | | This has multiple uses: * Single connection clients will not be considered threadsafe. This means certain settings could temporarily be adjusted. For example, a context manager could temporarily modify the encoding behavior for a set of commands. * We can introduce more thorough health checks that only happen when a connection is handed out from the connection pool. * Workloads that issue many commands to Redis should be slightly faster. Prior to this change, the client must retrieve a connection from the pool for each command.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Adds redis.selector, a module that provides the best selector strategy available on the current platform. A redis.selector polls a socket to provide two pieces of functionality: 1. Check whether data can be read from the socket. Prior versions of redis-py provided this behavior with just select.select(). select() has lots of limitations, most notably a limit of ~1024 file descriptors. Now that better selectors are available, this should make can_read() faster and able to accomodate more clients. See #1115 and #486 2. Check whether a socket is ready for a command to be sent. This doubles as a health check. It ensures that the socket is available for writing, has no data to read and has no known errors. Anytime a socket is disconnected or hung up, data is available to be read, typically zero bytes. ConnectionPool.get_connection has been modified to ensure that connections it returns are connected and are ready for a command to be sent. If get_connection encounters a case where a socket isn't ready for a command the connection is reconnected and checked again. TODO: more tests for this stuff. implement EPoll and KQueue selectors. Fixes #1115 Fixes #486
