8-8: Consider the performance implications of usingobjectfor locking.The change from
Locktoobjectfor thePadLockvariable is a simplification that enhances compatibility by using a standard locking mechanism. However, theLocktype likely provided more efficient locking mechanisms compared to a genericobject.Given that the locking logic remains intact, the change is approved as it is unlikely to introduce any correctness issues. But please consider the potential performance implications of this change.

27-27: Consider using a link for the contributor's GitHub profile.To improve readability and follow Markdown best practices, use a link format instead of a bare URL:
-- Support for System.Threading.Lock object that targets TFMs prior to .NET 9 (credits to Mark Cilia Vincenti, https://github.com/MarkCiliaVincenti/Backport.System.Threading.Lock) +- Support for System.Threading.Lock object that targets TFMs prior to .NET 9 (credits to [Mark Cilia Vincenti](https://github.com/MarkCiliaVincenti/Backport.System.Threading.Lock))This makes the changelog more readable and allows clicking the contributor's name to visit their profile.

8-8: Consider the performance implications of usingobjectfor locking.This change is similar to the one made in
src/Cuemon.Extensions.AspNetCore.Text.Json/Bootstrapper.cs. Please refer to the comment in that file for the performance and compatibility implications of usingobjectinstead ofLockfor thePadLockvariable.Given that the locking logic remains intact, the change is approved.

17-17: LGTM!The addition of the
Backport.System.Threading.Lockpackage reference enhances the project's threading capabilities by providing a backport of theLocktype for target frameworks where it is not available. This change improves compatibility with different target frameworks.
18-18: LGTM!The addition of the conditional
Usingdirective for theSystem.Threading.Locknamespace ensures that the appropriate locking mechanism is used when the target framework is compatible withnet9.0. This change improves the project's compatibility with different target framework versions.
19-19: LGTM!The addition of the conditional
Usingdirective for theBackport.System.Threading.Locknamespace ensures that the appropriate locking mechanism is used when the target framework is not compatible withnet9.0. This change improves the project's compatibility with different target framework versions.
20-20: LGTM, but verify theLockFactoryusage.The addition of the
Usingdirective for theBackport.System.Threading.LockFactorynamespace enables the usage of theLockFactorytype in the project. This change is approved.However, please verify that the
LockFactorytype is actually used in the project, as its usage is not visible in the provided code.Run the following script to verify the
LockFactoryusage:src/Cuemon.Extensions.AspNetCore.Xml/Bootstrapper.cs (1)
8-8: Verify the impact of changing the lock type fromLocktoobject.The change from
Locktoobjectmay impact the locking behavior and thread safety. TheLocktype likely provided specific locking behavior tailored for thread safety, while theobjecttype may require additional handling to ensure proper synchronization.Please ensure that the change does not introduce any synchronization issues or race conditions. If necessary, consider using a more specific locking mechanism that provides the required thread safety guarantees.

1-1: Verify the impact of removing the conditional compilation forLock.cs.The removal of the
<ItemGroup>element that contained a condition for targeting the .NET 9.0 framework suggests a change in how the project handles compatibility with .NET 9.0. TheLock.csfile will now always be included in the compilation process regardless of the target framework.Please ensure that the
Lock.csfile is compatible with all target frameworks and that its inclusion does not introduce any compatibility issues or unintended behavior. If the file was previously excluded for a specific reason, verify that the reason is no longer applicable or address any potential concerns.src/Cuemon.Core/Runtime/FileWatcher.cs (1)
14-14: Verify the impact of changing the_lockerfield type fromLocktoobject.The change broadens the scope of locking to a more generic object type rather than a specific locking class. This could impact how concurrency is managed within the
FileWatcherclass.Please ensure that the change does not introduce any concurrency issues or race conditions. The previous
Locktype may have provided specific locking behaviors that are not guaranteed with a genericobject.Run the following script to verify the usage of the
_lockerfield:Verification successful
Verified: The change from
Locktoobjectfor the_lockerfield is safe.The
_lockerfield is consistently used withinlockstatements, which ensures thread safety. The change to a genericobjectdoes not introduce concurrency issues, as thelockkeyword in C# provides mutual exclusion with any reference type.

I'm not sure what you did here Michael. Let me bring an example. |
I get what you are writing - but I also only want todo a min. of dependencies - also to avoid the risk of circular references. With these changes - although not utilized directly within Cuemon - your library is referenced in the confines of Cuemon.Extensions.Threading (which is a suitable place for 3rd party dependencies). |
|
Up to you as long as you understand the pros and cons. I didn't get into nitty gritty details of what the code does where and if it later becomes a hot path how you can easily help some optimisation through the locking. If you have any questions now or later don't hesitate to ask. Let's go! |
