When disposing a linked CancellationTokenSource, it should unregister itself from the
tokens that were linked into it.
public void CancelLinkedTokenSource ()
var cts = new CancellationTokenSource ();
bool canceled = false;
cts.Token.Register (() => canceled = true);
using (var linked = CancellationTokenSource.CreateLinkedTokenSource (cts.Token))
Assert.IsFalse (canceled, "#1");
Assert.IsFalse (cts.IsCancellationRequested, "#2");
Assert.IsTrue (canceled, "#3");
In this test, cts.Cancel() throws an ObjectDisposedException because it attempts to cancel the disposed 'linked'.
I have a fix for this, but I'm not sure whether it's correct and the best way of doing that:
Could you please have a look ?
On master and soon 2-10. Thanks!
