Release notes for LazyCache

Version 2.4.0

  • Bug fix for generic type - see #163. Thanks @gamblen
  • Bug fix for async wait and abs expiry. Thanks @allanrodriguez
  • (Very minor API change that is compiler compatible, but not binary compatible, so incrementing the minor.)

Version 2.1.3

  • Rename ExpirationMode.ImmediateExpiry => ExpirationMode.ImmediateEviction
  • Lovely new logo! (#133) Thanks to @doolali
  • Performance imporvements to reduce allocations in #134 - thanks @jnyrup

Version 2.1.2

  • Tweak key lock array size based on CPU count so larger for bigger machines (See PR #126 and discussion with @jjxtra)

Version 2.1.1

  • PR #126 (and issue #104) optimise cache key locking for faster performance under high CPU load and lots of concurrency. Thanks to @jjxtra

Version 2.1.0

  • Add options for expiration:
    • ExpirationMode.ImmediateExpiration which uses a timer to remove items from the cache as soon as they expire (more resource intensive)
    • ExpirationMode.LazyExpiration (existing default) which removes expired cache items when they are next accessed if they have expired.
  • Fix #96 AddExpirationToken with CancellationChangeToken is not being honored
  • Allow callers to pass MemoryCacheEntryOptions that is used at cache insertion time. This allows users to wire up callbacks and expiration tokens that fire at the correct time

Version 2.0.5

  • Fix #85 and #100 Absolute expiration not working with TimeSpan. Thank you to @Meberem and @Sinhk.
  • Fix #124 casing for PackageReference - by @jnyrup

Version 2.0.4

  • Fix #82 Make constructor resolution specific when using aspnet core dependency injection

Version 2.0.3

  • Fix #46 GetOrAdd and GetOrAddAsync returning nulll if there is already an item with the same key but different type in the cache (PR #106)

Version 2.0.2

  • Fix #71. Downgrade framework references to core framework 2.1 (not 2.2) since that is the current LTS release (PR #105)

Version 2.0.1

  • Add Ninject adapter (PR #61)

Version 2.0.0

  • BREAKING CHANGE Upgrade to netstandard2.0

  • BREAKING CHANGE Change underlying cache from System.Runtime.Caching to Microsft.Extension.Caching.Memory

  • BREAKING CHANGE Removed IAppCache.ObjectCache and changed to a cache provider model. To access the provider use IAppCache.CacheProvider. By default we use a singleton shared in-memory cache but add your own cache provider by implmenting the simple ICacheProvider.

  • BREAKING CHANGE changed from CacheItemPolicy to MemoryCacheEntryOptions. RemovedCallback is now PostEvictionCallbacks.

  • Added a new replaceable global static default cache provider

    Func<ICacheProvider> DefaultCacheProvider { get; }

    By default we use a shared in-memory cache but each instance can have it's underlying cache provider overridden from it's constructor.

  • Make methods on CachingService virtual/protected to enable

  • Add LazyCache.AspNetCore for dependency injection registration - ServiceCollection.AddLazyCache();

  • Update sample to use aspnet core and LazyCache.AspNetCore

  • New IAppCache.DefaultCachePolicy to replace CachingService.DefaultCacheDuration

  • Moved most CachingService method overloads to extension methods on IAppCache in AppCacheExtensions. API should be backwards compatible but as now extension methods this is technically an API breaking changing.

  • Added new methods on IAppCache to allow you to specify cache expiry options on executution of the item factory

    GetOrAdd<T>(string key, Func<ICacheEntry, T> addItemFactory)

    Task<T> GetOrAddAsync<T>(string key, Func<ICacheEntry, Task<T>> addItemFactory)

Version 0.7.1

  • Fix async/sync interopability bug, see #12

Version 0.7

  • BREAKING CHANGE Upgrade to .net 4.5
  • Added ObjectCache property to IAppCache to allow access to underlying cache for operations such as cache clearing
  • Support caching asynchronous tasks with GetOrAddAsync methods
  • Add ApiAsyncCachingSample to demonstrate the caching the results of SQL Queries in a WebApi controller
  • Add badges to Readme

Version 0.6

  • Fixed issue with RemovedCallback not unwrapping the Lazy used to thread safe the cache item.

Version 0.5

  • Initial release of CachingService and interface IAppCache.
  • Readme
  • Core unit tests.
