What this system is

RediStack is a Swift client library for Redis, built on SwiftNIO, that provides a type-safe API for interacting with Redis data structures and messaging systems. It supports connection pooling, Pub/Sub messaging, and a comprehensive suite of Redis commands including keys, hashes, lists, sets, and sorted sets. The system also includes utilities for testing and automated contributor management.

Features

Add PubSub support and refactor pipeline setup

Introduces support for Redis Pub/Sub by adding a dedicated \RedisPubSubHandler\ to the SwiftNIO channel pipeline, allowing clients to subscribe to and receive Pub/Sub messages. The \ChannelPipeline\ is extended with methods to add, retrieve, and remove the Pub/Sub handler, ensuring it is inserted before the standard command handler. Additionally, \ClientBootstrap\ is updated with a convenience method \makeRedisTCPClient\ that automatically configures the base Redis handlers (encoder, decoder, and command handler) for TCP connections. A small internal extension on \Array\ is also added to support initial capacity reservation.

Add Redis Set data type support

A new \RedisSet\<Element\>\ struct is introduced in the \Sources/RedisTypes\ module, providing a typed, reusable interface for interacting with Redis Sets. The implementation includes methods for common set operations such as \insert\, \remove\, \move\, and \popRandomElement\, allowing users to perform set-based Redis commands with Swift type safety.

Add Redis connection pooling and Pub/Sub support

RediStack introduces a new \RedisConnectionPool\ that manages a pool of Redis connections to improve latency and handle cluster management. The update adds support for Redis Pub/Sub messaging, including \subscribe\, \psubscribe\, \unsubscribe\, and \punsubscribe\ methods on the \RedisClient\ protocol. Additionally, the library adds a type-safe \RedisChannelName\ wrapper for channel names and a \ConnectionPool\ implementation with configurable retry strategies and connection count behaviors.

Added RediStack test utilities for connection and pool testing

The RediStackTestUtils module now includes helper classes for integration testing, including a mock Redis server for unit tests, convenience extensions for string and Redis configuration, and base test case classes for both single Redis connections and connection pools. These utilities allow developers to easily spin up test environments and verify connection pool behavior.

Automated generation of the contributors list

A new shell script, generate\_contributors\_list.sh, has been added to the scripts directory. This script automates the creation of the CONTRIBUTORS.txt file by extracting the list of individuals and organizations who have contributed source code to the project, including copyright holders like Apple Inc. and Globant Inc. This ensures the contributors list remains up-to-date and accurately reflects the project's history.

Comprehensive Redis command implementations for connection, keys, hashes, lists, sets, sorted sets, and pub/sub

The RediStack library introduces a full suite of Redis command implementations, providing type-safe Swift APIs for core data structures and operations. This includes connection management (AUTH, SELECT, PING, ECHO), key operations (DEL, EXISTS, EXPIRE, TTL, KEYS, SCAN), hash manipulations (HGET, HSET, HDEL, HMGET, etc.), list operations (LPUSH, LPOP, BLPOP, BRPOP), set operations (SADD, SMEMBERS, SDIFF, etc.), sorted set commands (ZADD, BZPOPMIN/MAX), and Pub/Sub support (PUBLISH, PUBSUB). Each command is exposed via the \RedisCommand\ struct and conveniently wrapped on \RedisClient\ for direct invocation, enabling developers to interact with Redis using strongly-typed, idiomatic Swift code.

Introduce Pub/Sub support with dedicated channel handlers

Added Redis Pub/Sub capabilities by introducing new channel handlers: \RedisPubSubHandler\ manages subscriptions and message delivery, while \RedisByteDecoder\, \RedisMessageEncoder\, and \RedisCommandHandler\ handle the underlying RESP protocol encoding and decoding for the connection pipeline.

Introduce RESP protocol translation and value types

Adds the \RESPTranslator\ struct and \RESPValue\ enum to handle serialization and deserialization of the Redis Serialization Protocol (RESP). The \RESPTranslator\ provides methods to write \RESPValue\ instances into \ByteBuffer\ and parse raw bytes into \RESPValue\ objects, including specific handling for simple strings, bulk strings, integers, arrays, and errors. The \RESPValue\ enum represents the various data types defined by the RESP specification, with support for conversion to and from Swift types like \String\, \Int\, \Double\, and \Array\ via the \RESPValueConvertible\ protocol. This enables the library to communicate with Redis servers using the standard RESP format.

Behavioural changes

Rebrand to RediStack and adopt Apache 2.0 license

The project has been renamed from \nio-redis\ (or \RedisNIO\) to \*\RediStack\\*. As part of this rebranding, the license has been changed from MIT to Apache 2.0, and the repository now includes a comprehensive \README.md\ detailing the new identity, supported Swift and Redis versions, and contribution guidelines.

(repo-wide) · high confidence

Test coverage

Added Linux test discovery stub; Added integration tests for Redis set operations; Added tests for RediStack configuration, connection pooling, and protocol translation; Added unit tests for RediStack channel handlers; Expanded integration test coverage for Redis commands; Integration tests for Redis connection pool, logging, and service discovery.

Dependencies

Initial release of RediStack package and CocoaPods spec

The project is now available as a Swift Package Manager package (Package.swift) and a CocoaPods specification (mine.podspec). The Swift package defines the 'RediStack' library along with 'RedisTypes' and test utilities, depending on Swift NIO, SwiftLog, SwiftMetrics, and Swift Service Discovery. The CocoaPods spec mirrors these dependencies, establishing the initial build and distribution configuration for the library.

  • Inconsistent parameter arity for pattern unsubscribe. RedisClient.punsubscribe takes a single String, while RedisConnection and RedisConnectionPool take an array [String]. This mirrors the inconsistency in unsubscribe but is exacerbated by the String type mismatch with psubscribe.
  • Inconsistent parameter arity for unsubscribe. RedisClient.unsubscribe takes a single RedisChannelName, whereas RedisConnection and RedisConnectionPool take an array [RedisChannelName]. This breaks the expectation of a uniform API across the client hierarchy.
  • Inconsistent parameter types for pattern subscription. The standard subscribe method accepts [RedisChannelName], but the pattern subscription psubscribe accepts [String]. This forces users to convert between String and RedisChannelName depending on whether they are subscribing to exact names or patterns, despite RedisChannelName being the primary type for channel identification in the library.
