TempResourceFile.Dispose causes run to hang about nunit-console

[tom-dudley]

I can't wrap my head around why the loop would ever be infinite. It seems to me that GetDirectoryPath is guaranteed to either be null or empty once it hits the root node. I can only think that the function is somehow returning the path which was passed in, which is highly doubtful.

Why would a non-parallelizable STA test make this more likely?

The comment about non-parallelizable STA tests relates to the original issue that was written against the framework. I suspected that the call to Delete might not return. However, it's irrelevant now that we are talking about the engine tests.

There may no longer be an issue. The only thing that bothers me about that method right now is the use of the name path for two purposes. It takes some knowledge of C# syntax to understand which value is being used in a given statement.

I think I'd be ready to close this in any case.

I just looked a bit into this issue, as and I cannot see how the code could hang. The only problem I can see is that sometimes the Dispose will not remove the file/folder due to an exception being thrown, or possibly leaving empty folders behind if other threads/processes have a delete share to the file making the Delete method return before actually deleting the file (see e.g. https://stackoverflow.com/questions/50295265/file-exists-returns-true-after-file-delete).

@nunit/engine-team I propose to delete the class TempResourceFile since it is currently unused in the project.
