I'm wondering, would it be a problem of chunk size when using L.hGetContents? Since the data to read is shorter than the default chunk size (32k), would it cause problems? Yves Parès wrote:
Okay, so I turned off every buffering using hSetBuffering hdl NoBuffering on both Client and Server, but that doesn't fix it... BTW, I tried to do the same without your package, i.e. simply through Lazy ByteString and Binary, but it doesn't work either, I come up against the same issue.

Hmm, I am guessing it is more likely that the problem is that the I/O system changed from 6.10.4 to 6.12.1 somehow in a way that broke the package. You could try turning off all buffering in the handle using hSetBuffering and seeing if that works.

Weird...
I use GHC 6.12.1, and I run Ubuntu 9.10 (32bits version).
Would have I miss something? Like a flush or a close? Logically, I don't see where I would...

Yay, I'm glad to see someone else using my package. :-)
Hmm, your program seems to work for me. I compiled and ran the Server (with ghc --make), then compiled and ran the Client, and then typed
Operation 1.0 Mult 2.0
into the Client process, and the result it got was
2.0
with the output
Just 2.0
on the Server.
I got the same results running this on Mac OSX and (Gentoo) Linux, with GHC 10.4. What platform/GHC version are you running it on?
Cheers, Greg

Hello,
I'm trying to use the packages Network and Control.Monad.BinaryProtocol together, with a very simple program in which a client sends an operation to the server, which computes the result and sends it back.
But the server holds when trying to receive (Server.hs, line 22), whereas the client has actually sent the data (Client.hs, line 17). The server stops to hold only when the client is killed with a Ctrl-C.
This should be rather simple, and I can't get to know why it doesn't work.
