CVS: about 2 days ago (6-15-99)
OperatingSystem: Windows NT
Synopsis: Sockets on NT 8.1.1 broken
ReproducibleScript:
Ex code from Welch, 2nd Rev. 16_2.tcl, 16_3.tcl
Similar from http://www.sco.com/Technology/tcl/SocketExample.html
My code is a bit more complex, but more careful wrt blocking. Same
results
as either the above.
ObservedBehavior:
Can't get any socket communication between server (tclsh8.0 on FreeBSD)
and
client (tclsh81.exe on NT4, SP5). Nothing. Blocks like a bitch. Server
accepts
request. Blocking client hangs right away. If I set up fileevent to wait
for
writable socket, it never happens. Ever. If I click on the Icon,
wish81.exe is called, but console never shows up, and process never
dies. I need to kill manually from Task Manager.
When I downgraded to Tcl8.0.5, everything worked fine. All 3 cited
examples.
DesiredBehavior:
Would expect a writable socket and proper eventloop. Sometimes can get a
writable socket, but never consistent results.
Comments:
I am not experienced w/ Tcl for NT. Just used for first time 2 days ago.
I very well could be ignoring something important.

and you can get the latest files from the CVS repository (main
trunk). It will be released with 8.1.2 (or get win/tclWinSock.c
from 8.1.0).
