[BUG] FusionHybridCache RemoveByTagAsync("*") does not invalidate whole cache

[vrbyjimmy]

Describe the bug

HybridCache implementation does not clear all data when called RemoveByTagAsync("*") as is specified by Microsoft documentation

To Reproduce

using Microsoft.Extensions.Caching.Hybrid;
using Microsoft.Extensions.DependencyInjection;
using ZiggyCreatures.Caching.Fusion;

var serviceProvider = new ServiceCollection()
.AddFusionCache()
.WithDefaultEntryOptions(options =>
{
options.Duration = TimeSpan.FromMinutes(10);
})
.AsHybridCache()
.Services
.BuildServiceProvider();

var cache = serviceProvider.GetRequiredService<HybridCache>();

await cache.SetAsync("Key", "NotExpected");

await cache.RemoveByTagAsync("*");

var value = await cache.GetOrCreateAsync("Key", async t => await Task.FromResult("Expected"));

if (value != "Expected")
{
throw new Exception("Unexpected value: " + value);
}

Expected behavior

After calling RemoveByTagAsync("*") all data in cache should be removed

Versions

I've encountered this issue on:

• FusionCache: 2.5.0
• .NET version: 10.0
• OS version: Windows 11

Hi @vrbyjimmy , damn you're right!

It was not part of the API surface area, and I honestly discovered only later that there was this "special behavior" and, when I did, I didn't make 2+2 to make it work in the FusionCache adapter, too.

Will fix it asap and release a new version, hold tight.

Thanks for reporting this.

Fixed with #601
