Yes, from what I read, I assumed it had this behavior. But, then, I don't see why the server holds... I've posted a mail on Haskell-Cafe called "Network: buffering troubles", in which I put a smaller example which reproduces this problem.
I know :)
I have now tested it, with both (simple) servers and I can't reproduce the problem (ghc-6.12.1 and ghc-6.10.3).
Installed binary-protocol and tried the original (no hSetBuffering), that also works flawlessly (ghc-6.12.1 on openSuSE 11.1). Server: $ ../BeginnersTesting/Server I wait for a client... Result: Just 1.6190478 I wait for a client... Result: Just 12.0 I wait for a client... Result: Nothing ^C Client: $ ./Client localhost Operation? Operation 3.4 Div 2.1 Operation sent. 1.6190478 Operation? Operation 17 Minus 5 Operation sent. 12.0 Operation? Stop Operation sent. Seems to be something with Ubuntu. Maybe somebody else on Ubuntu could test it?
