It's probably worth opening a bug against curl, even if we have a work around. Their bug tracker is here.

I was thinking about it. I would need to probably isolate C repo and show behavior with some public server.


// Override the default DNS cache timeout. libcurl defaults to a 1 minute
// timeout, but we extend that to match the Windows timeout of 10 minutes.

This seems like it's hiding a symptom. Is there an underlying problem we should be fixing instead?

I could be wrong but I don't think so. We initialize instances when the class loads. And then we skip the test and we immediately hit Dispose() Now, on busy/slow system this happens before the task runs end executes the listener call. That can either lead to timeout, object disposed exception or invalid operation based on exact timing. In that case I saw on ARM32 the actual test was skipped but hit "Error: (not Fail) just loading and unloading the test class.

What's the stack of the exceptions you're seeing?

I see, ok. GetContext documents both InvalidOperationException and ObjectDisposedException as occurring in cases like this, where the HttpListener may not be listening or has been disposed of already, so... ok. Subsequently it might be nice to try to restructure the tests to avoid this, but I agree your tactical fix is good to go ahead with now.

I originally started on path to add synchronization.
But than it looked like unnecessary complexity for cases when we do not run the test anyway.
