Unreleased

0.22.2

  • Fix the sentinel client to properly extend timeout for blocking commands.
  • Fix IPv6 support in RedisClient::Config#server_url.

0.22.1

  • Fix ProtocolError: Unknown sigil type errors when using SSL connection. See #190.

0.22.0

  • Made various performance optimizations to the Ruby driver. See #184.
  • Always assume UTF-8 encoding instead of relying on Encoding.default_external.
  • Add exception flag in pipelined allowing failed commands to be returned in the result array when set to false. See #187.

0.21.1

  • Handle unresolved Sentinel master/replica error when displaying server URL in exceptions. See #182.

0.21.0

  • Include redis server URL in most error messages. See #178.
  • Close Redis Sentinel connection after resolving role. See #176.

0.20.0

  • Accept unix:// schemes as well as simple paths in the url: config parameter. #170.
  • Make basic usage Ractor compatible.

0.19.1

  • Fixed a bug in hiredis-client that could cause a crash if interrupted by Timeout.timeout or other Thread#raise based mecanism.
  • Fixed a GC bug that could cause crashes in hiredis-client.

0.19.0

  • Revalidate connection in RedisClient#connected?
  • Eagerly fail if db: isn't an Integer. #151.

0.18.0

  • Expose more connection details such as host, db, etc on RedisClient.

0.17.1

  • Add support for NaN in RESP3 protocol doubles. This was initially missing from the spec and added about a year ago.

0.17.0

  • Adds sentinel_username and sentinel_password options for RedisClient#sentinel

0.16.0

  • Add RedisClient#disable_reconnection.
  • Reverted the special discard of connection. A regular close(2) should be enough.

0.15.0

  • Discard sockets rather than explictly close them when a fork is detected. #126.
  • Allow to configure sentinel client via url. #117.
  • Fix sentinel to preverse the auth/password when refreshing the sentinel list. #107.

0.14.1

  • Include the timeout value in TimeoutError messages.
  • Fix connection keep-alive on FreeBSD. #102.

0.14.0

  • Implement Sentinels list automatic refresh.
  • hiredis binding now implement GC compaction and write barriers.
  • hiredis binding now properly release the GVL around connect(2).
  • hiredis the client memory is now re-used on reconnection when possible to reduce allocation churn.

0.13.0

  • Enable TCP keepalive on redis sockets. It sends a keep alive probe every 15 seconds for 2 minutes. #94.

0.12.2

  • Cache calls to Process.pid on Ruby 3.1+. #91.

0.12.1

  • Improve compatibility with uri 0.12.0 (default in Ruby 3.2.0).

0.12.0

  • hiredis: fix a compilation issue on macOS and Ruby 3.2.0. See: #79
  • Close connection on MASTERDOWN errors. Similar to READONLY.
  • Add a circuit_breaker configuration option for cache servers and other disposable Redis servers. See #55 / #70

0.11.2

  • Close connection on READONLY errors. Fix: #64
  • Handle Redis 6+ servers with a missing HELLO command. See: #67
  • Validate url parameters a bit more strictly. Fix #61

0.11.1

  • hiredis: Workaround a compilation bug with Xcode 14.0. Fix: #58
  • Accept URI instances as uri parameter.

0.11.0

  • hiredis: do not eagerly close the connection on read timeout, let the caller decide if a timeout is final.
  • Add Config#custom to store configuration metadata. It can be used for per server middleware configuration.

0.10.0

  • Added instance scoped middlewares. See: #53
  • Allow subclasses of accepted types as command arguments. Fix: #51
  • Improve hiredis driver error messages.

0.9.0

  • Automatically reconnect if the process was forked.

0.8.1

  • Make the client resilient to Timeout.timeout or Thread#kill use (it still is very much discouraged to use either). Use of async interrupts could cause responses to be interleaved.
  • hiredis: handle commands returning a top-level false (no command does this today, but some extensions might).
  • Workaround a bug in Ruby 2.6 causing a crash if the debug gem is enabled when redis-client is being required. Fix: #48

0.8.0

  • Add a connect interface to the instrumentation API.

0.7.4

  • Fix the instrumentation API to be called even for authentication commands.
  • Fix url: configuration to accept a trailing slash.

  • Fix #pubsub being called when reconnection is disabled (redis-rb compatibility fix).

0.7.0

  • Sentinel config now accept a list of URLs: RedisClient.sentinel(sentinels: %w(redis://example.com:7000 redis://example.com:7001 ..))

0.6.2

  • Fix sentinel to not connected to s_down or o_down replicas.
