Data not removed in redis

[softworm]

Description

RemoveByPrefix does not remove data in redis if a 'prefix' is included in DBConfig.ConnectionStrings

Steps to Reproduce

1. DBConfig.ConnectionStrings = new List { "123.123.123.123:6379,password=123,prefix=hmm:" };
2. [EasyCachingEvict(CacheKeyPrefix="users", IsAll=true, IsBefore=true)]

Related code

Expected behavior: delete keys like hmm:users:1 , hmm:users:2

Actual behavior: keys are not deleted

@softworm Thanks for your interest in this project.

According to the information you provided, there is no way to judge that there is a problem.

Could you provide more information for this issue?

[softworm]

Thanks for your reply. Here is a demo application to reproduce the problem.

program.cs

public class Program
{
	public static void Main(string[] args)
	{
		CreateHostBuilder(args).Build().Run();
	}

	public static IHostBuilder CreateHostBuilder(string[] args) =>
		Host.CreateDefaultBuilder(args)
			.ConfigureWebHostDefaults(webBuilder =>
			{
				webBuilder.UseStartup<Startup>();
			}).UseServiceProviderFactory(new DynamicProxyServiceProviderFactory());
}

startup.cs

public void ConfigureServices(IServiceCollection services)
{
            services.AddScoped<IFooService, FooService>();

            services.AddEasyCaching(option =>
            {
                option.WithJson("json1");
                option.UseCSRedis(config =>
                {
                    config.SerializerName = "json1";
                    config.DBConfig = new CSRedisDBOptions
                    {
                        ConnectionStrings = new List<string>
                        {
                            "123.45.123.45:6379,password=12345,prefix=msys:"
                        }
                    };
                }, "default");
            });
            services.ConfigureAspectCoreInterceptor(o => o.CacheProviderName = "default");
}

notice the 'prefix' in the connection string, it may cause the data not remove problem.

service

    public interface IFooService
    {
        [EasyCachingAble(CacheKeyPrefix = "foo")]
        string GetList();


        [EasyCachingEvict(CacheKeyPrefix = "foo", IsAll = true, IsBefore = true)]
        void Remove();


        [EasyCachingEvict(CacheKeyPrefix = "foo", IsAll = true, IsBefore = true)]
        void Update();
    }

    public class FooService : IFooService
    {
        public string GetList()
        {
            return "hello foo";
        }

        public void Remove()
        {
            Console.WriteLine("remove called");
        }

        public void Update()
        {
            Console.WriteLine("update called");
        }
    }

Test steps:

1. When I call GetList method, data is stored in redis quite well.

123.45.123.45:6379> keys msys*
(empty list or set)
123.45.123.45:6379> keys msys*
1) "msys:foo:0"

2. However, when I call Remove or Update method, the data is still there.

123.45.123.45:6379> keys msys*
1) "msys:foo:0"

Test without prefix

If I remove the 'prefix' in connection string, everything goes well as expected.

# before call getlist
123.45.123.45:6379> keys foo*
(empty list or set)

# after call getlist
123.45.123.45:6379> keys foo*
1) "foo:0"

# after call update
123.45.123.45:6379> keys foo*
(empty list or set)

OK, I will have a try later this day.
