Initial SslStream stress app work by eiriktsarpalis · Pull Request #290 · dotnet/runtime

eiriktsarpalis · 2019-11-26T14:37:53Z

Adds the changes initially created for the corefx repo in dotnet/corefx#42560

Adds a console application for stress testing the SslStream class. The work somewhat imitates the setup that we already have in the http stress app: the app will open a fixed number of concurrent connections and run the stress scenaria for a fixed time period per connection (defaults at 2 minutes).
Unlike http2 there are no multiplexing concerns here, so the potential for stress tests seems less interesting. I've only included a single scenario for the moment: sending and echoing back of random data with basic integrity checks, using randomized permutations of Write, WriteAsync, WriteByte and Flush methods. I haven't been able to reproduce failures so far, though I haven't run the app for extensive periods of time yet.

I'm investigating a hanging behaviour that reproduces in the linux pipeline, which is why I haven't merged this yet.
