           Summary: AcceptEx detaches the socket from its IO completion

Hello,

On a server I have a listening socket
    lListeningSocket := socket (PF_INET, SOCK_STREAM, IPPROTO_TCP);
    CreateIoCompletionPort (lListeningSocket, lIoCompletionPort, 0, 0);
    bind (lListeningSocket, PSockAddr (@lAddress)^, SizeOf (TSockAddrIn));
    listen (lListeningSocket, 1);
and I prepare a socket for a new connection
    lSocket := socket (PF_INET, SOCK_STREAM, IPPROTO_TCP);
    CreateIoCompletionPort (lSocket, lIoCompletionPort, 0, 0);
then call AcceptEx
    lPtrAcceptEx (lListeningSocket, lSocket, ...);

GetQueuedCompletionStatus (lIoCompletionPort, ...) signals completion for
AcceptEx for an incoming connection (so CreateIoCompletionPort
(lListeningSocket, ...) works fine), but never signals completion for events on
lSocket, not even a disconnection.

If I call again
   CreateIoCompletionPort (lSocket, lIoCompletionPort, 0, 0);
after the completion of AcceptEx, it works fine.
So AcceptEx as detached lSocket from the IO completion port.

To help reproducting it, I created a little command line server BugAcceptEx.exe
Here attached is the code (Delphi) and the executable.

In a command prompt run
  BugAcceptEx 1234
and in another command prompt
  telnet localhost 1234
and press a key

Under Windows it works fine, under Mac + Wine the server signals the incoming
connection but never signals data nor disconnection.

Now if you do
  BugAcceptEx 1235 WithPatch
and
  telnet localhost 1235
it works fine

Thank you for your help.

Regards,

Michel Terrisse
