syncShutdownGracefully() hangs Chapter 11 Tests

📚 Official Books Server Side Swift with Vapor
1

Chapter 11 unit test execution hangs after tearDown executed once. Sometimes all tests are executed successfully and sometimes some of tests are left unexecuted. In either case I never see “Test Succeeded”.

If I comment out the call to syncShutdownGracefully() in tearDown() then the tests execute successfully and to completion.

I’ve rebuild the Xcode project ( vapor Xcode -y) and reset the PostgreSQL DBs in Docker (both vapor and vapor-test) and get the same results.

I can run each test individually and every one succeeds.

I’m using swift-no 1.14.1

Any pointers appreciated.

Hmm I think this is one of the threading issues that currently exists in Vapor - there’s a bug with the memory cache that exhibits this behaviour and I think it’s this. For now you can remove the call to syncShutdownGracefully to make it work

Thanks, will do. Really enjoying your book. I have recommended it to others.
