[Help-smalltalk] Problems with Socket>>isPeerAlive

[Robin Redeker]

Hi,

in the attachment there is a piece of code, which establishes a tcp
connection to a listening socket and reads all arriving data from there.

I thought i could use Socket>>isPeerAlive to test whether i can expect
further data from the prev. listening socket.

But then i shutdown the end point of the connection (the prev. listening
socket) isPeerAlive still signals true.

Is this wrong usage of isPeerAlive? Should i rather use Socket>>atEnd to
test whether the connection is still alive? Or something else?

Steps to reproduce:

  - open a listening socket on localhost port 1234
    (i use netcat: 'nc -l -p 1234')
  - start the Communicator.st like this:
    gst Communicator.st
  - ctrl-c/abort the netcat/listening process after Communicator
    connected
  - watch 'read hunk []' scrolling on the screen where you started gst.
