Subject Re: Setting up the CI pipeline
Date Tue, 25 Nov 2014 20:41:47 GMT
I think I found the issue with the tests taking forever to run.
TestDoubleMockGraphTokenFilterRandom was running seemingly indefinitely --
I don't actually think now that it would run indefinitely, I just didn't
feel like waiting on it after a good number of minutes.

I noticed a strange behavior when I was stepping through the test to see
what was going on -- the console output would catch up every few times I'd
step over a statement, as if there were a background thread going on.

I do think there is some background thread issue, but it isn't with the
Lucene.net code (as far as I can tell) -- it appears to be with NUnit
itself or perhaps the VS test framework. But since it happened on the CI
server too, I'm leaning towards NUnit.

What I actually think is happening is that the Console output is handled
asynchronously in some background thread, and there's just *so much* logging
happening in the LookaheadTokenFilter et al that when DEBUG evaluates to
true and the Console.WriteLine calls stack up, it takes forever to get
through them all. Running the tests in Release mode (when the
Console.WriteLine is not called) or manually setting DEBUG and VERBOSE to
evaluate to false even in Debug configuration, causes the test to pass in
15 seconds on my machine.

Wyatt, can you try running the build and tests in Release mode and see if
it runs better for you? We might also be able to get through this by
reducing the logging by commenting out the Console.WriteLine calls.
