Re: Latest snapshot with XP SP2 and unison and cvs
Hi All... I have a testcase. It uses unison-2.9.1.exe available from http://www.cis.upenn.edu/~bcpierce/home.html (from here go to unison, downloads, current stable version, and select unison.win32-gtkui.exe) On a machine with XP, SP2, this test hangs and with XP or 2000 it executes to completion. The recipie is as follows (assuming you have openssh client and server set up): download unison rename the executable to unison.exe and place it somewhere on your PATH. in a cmd (not bash) shell type unison C:/ ssh://localhost/C:/ -testserver -rshargs -v -v -v thats it. Unison will use the ssh client to run a copy of itself and talk to it for the test. This does not work from a bash shell...never has. But...you can run it from strace cmd inside a bash shell to get strace output. Up until XP SP2 and the latest cygwin, I have been using it this way for years without a hitch. On XP SP2 the results are 100% repeatable. It hangs in the same place every time. I have run sshd in debug mode and found nothing unusual there. It appears to be a client problem. An XP SP2 server is fine, but the XP SP2 client (with the latest cygwin1.dll or snapshots I tried) hangs.

What can I do that would be usefull? I'm not sure how to tell where things are hanging, because unison-2.9.1 is a win32 program that invokes a cygwin ssh client. I did confirm that it is a ssh client side issue. That is, an XP SP2 machine is fine as the server, but not as the client.

I thought the same, but it's not the firewall. I tested this a few minutes ago. The change in behaviour is apparently related to the changes in the pipe code made on 2004-09-02.

Re: Latest snapshot with XP SP2 and unison and cvs
I just updated an xp machine to sp2 and unison-2.9.1 (the win32 version) using ssh (cygwin) started hanging. I have done a clean install of cygwin and am running with the 16sep snapshot. cvs (cygwin) works fine with ssh. unison hangs with ssh. Because win32 unison will not run under bash, I opened a cygwin bash window, did an strace of cmd and then ran unison. The strace is attached. Karl, you may want to try a later version of Unison. 2.9.1 is pretty old now, and although I don't know about that version specifically, I know that there have been hanging bugs in other versions. A Cygwin version of Unison 2.10.2 has just been released; you should be able to find it in the Cygwin setup utility. However, the archive format has changed, so you will have to be using version 2.10.x (I believe) on both hosts or Unison will complain. It will also have to resync its archive lists. Good luck, Andrew. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
