Motivation:
The TTL and PTTL commands are missing.
Modifications:
- Add TTL and PTTL commands
- Add integration tests
Result:
- Users can query the ttl in seconds or milliseconds of a key
Motivation:
The EXISTS command was missing.
Modifications:
- Add 'EXISTS' to basic commands
- Add integration tests
Result:
The existence of a key can be checked.
Motivation:
It was noticed that many of the commands are cumbersome to use with boilerplate type casting for each use that can be simplified within the library
by doing type conversion before returning the value to an end user.
Modifications:
Many APIs that return a `RESPValue` now have overloads to provide a `RESPValueConvertible` type that the value will be turned into before being returned.
For a few APIs that returned `RESPValue`, they did so as an Optional. Those APIs have been changed to always provide a `RESPValue` and return `.null` in cases where `nil` was returned.
In addition, the `@inlinable` attribute has been removed from any non-generic command API.
Result:
Developers should have less code boilerplate for turning values from `RESPValue` to their desired type with many commands.
Motivation:
Inspired by Swift by Sundell's article on type-safe identifers, the goal of this commit is to have the compiler
assist in preventing incorrect Redis key values from being used in API calls.
See https://www.swiftbysundell.com/articles/type-safe-identifiers-in-swift/ for the inspiration.
Modifications:
- Add new `RedisKey` struct that wraps around a single `String` value that conforms to several expected protocols
(Hashable, Comparable, Codable, etc.)
- Change all command APIs to require `RedisKey` rather than plain strings
Result:
When encountering an API requiring a RedisKey, it should be much more apparant at the use site what form a value should take.
Motivation:
For ergonomics, users sometimes want to provide arguments as a variadic list rather than an array.
Modifications:
- Add variadic overloads for almost all methods that accept lists of homogenous types
Result:
Users should have more flexibility in the way arguments are passed to command methods
Motivation:
After working with RedisKit with RediStackTestUtils as a dependency, it was realized how opinionated the module is in how RedisConnections can be created in test environments.
Modifications:
Require more information, with reasonable defaults for `RedisConnection.init()`. Provide subclass hooks for `RedisIntegrationTestCase` for implementors to make decisions for themselves at how to connect to Redis.
Result:
Users should have more freedom in how they connect to Redis in their units tests.
Motivation:
For users looking to contribute, and for those looking to validate the library, it was unclear what tests require an actual connection to a Redis instance in order to run.
Modifications:
Add a `RediStackIntegrationTests` that takes all tests that require a Redis instance in order to run.
Result:
Those looking to run just unit tests, or contribute new tests, can now directly point to a specific testTarget as defined in the Package manifest.
