When we upgrade from .NET6 to .NET7, RedLock fails to obtain locks.
Is .NET7 supported?
Thanks

I haven't tried using it with .NET 7, but it should work (and if it doesn't for some reason then I'd like to fix it)

So I've just run the unit tests locally targeting net7.0 and they all passed.

Are you able to provide a repro for this failure, or enable the RedLock logging and supply those?

Hi
Is it possible to assist us in how to enable logging. We cannot find any docs on this feature.
Thanks

Hi, to enable logging you need to pass an instance of ILoggerFactory as a parameter when you create your RedLockFactory

Nothing specifically documented, but you can see it in the tests (e.g. https://github.com/samcook/RedLock.net/blob/master/RedLockNet.Tests/RedLockTests.cs#L119).

You just need to get hold of an instance of ILoggerFactory (e.g. from your DI container) and pass it to RedLockFactory.Create(endpoints, loggerFactory).

Not related to .NET 7 but the lib fails at aquiring locks if StackExchange.Redis is upgraded to any version later than 2.6.48

Creating the RedLockFactory by:

_factory = RedLockFactory.Create(connection, loggerFactory);

where connection is a List<RedLockEndPoint> and each RedLockEndPoint has:

redLockEndPoint.EndPoints.Add(new DnsEndPoint("somehost", 6379));
redLockEndPoint.Password = "somepassword";
redLockEndPoint.RedisDatabase = 0;
redLockEndPoint.RedisKeyFormat = "someprefix:redlock:" + "{0}";

When StackExchange.Redis is downgraded to 2.6.48, everything works as expected

Would appreciate if you could let us know if this can be fixed or not so that we can adjust our application appropriately.
Thanks

@hn1 Are you able to set the logging level to Debug and capture the logs from a failed attempt to get a lock?

Also what version of RedLock.net and StackExchange.Redis are you using? And what OS/platform are you running on? What redis version or service are you running against?

Does increasing the ConnectionTimeout property (e.g. to 1000ms) on the RedLockEndpoint make any difference?

I have so far been unable to reproduce this issue with a console application targeting both net6.0 and net7.0 using the latest versions of RedLock.net and StackExchange.Redis, running on both windows and under Linux using WSL. If you're able to provide a simple example that reproduces the issue that would be very helpful.

@jonnepmyra I'm also unable to reproduce this, if you're able to provide a repro example could you open a new issue about it?

RedLock works perfectly on .NET6 - It is only after upgrading to .NET7 or .NET 8 that we have these issues. So the version numbers and OS should not be an issue as otherwise it would also not work on .NET6 which it does without any issues.

We are using the RedLock version 2.3.2We are also using the Microsoft.Extensions.Caching.StackExchangeRedis version 8.0.0 (for .NET 8)We are running on windows.
Under the dependencies in RedLock we noticed StackExchange.Redis (2.6.122) - could this be the issue?

This is the Debug log:

Thanks @hn1.

According to log message you posted, StackExchange.Redis is not able to connect to redis on localhost:6379 (which is why it's failing to acquire a lock). I'm assuming you have a redis server running there, if it works under .NET 6.0.

I updated my test application to use StackExchange.Redis 2.6.112 and it's still working just fine for me. 🤔

Are you able to make a sample project that reproduces the issue for you, which I'm able to run to try and see what the problem is?

That's unfortunate, if there is a problem with RedLock I'd like to figure out what it is, but without being able to reproduce it I'm not really able to get any further.

In your example you supplied the debug logs for, is your redis server running on localhost:6379?

How are you initialising the RedLockFactory?

Can you show the configuration you're passing to RedLockFactory.Create()?

I'm using RedLock in .Net 5, .Net 6, .Net7 and .Net8 without problem. I have not have any problem with different versions of SE.Redis either in any of the dotnet version and combinations.

What I have seen is in other communications is that resolution of hostname localhost some times is resolved to the IP4 address and sometimes to the IP6 address and to get around that the usage of IP directly has solved the problem.

Will you have the same problem if you using the IP address insted of hostname?

Interesting, thanks for the suggestion @Tasteful.

@hn1 out of interest, we're you using your own instances of ConnectionMultiplexer with RedLock.net, or were you letting it establish its own connection?
