[darcs-devel] [issue504] Problem with darcsdir distribution when using SSH_PORT

[Dennis Lambe]

New submission from Dennis Lambe <dlambe at preferred-mfg.com>:

I am using the darcsdir-cygwin-1.0.9.tar.bz2 distribution of darcs 
provided by zooko.com on Windows XP.  I'm using the SSH_PORT environment 
variable to connect to an SSH server that is running on a non-standard 
port.  Darcs calls ssh with the -p option to set the alternate port, but 
since your ssh.exe is really PuTTY's plink.exe it's looking for -P 
(capital 'p') instead and certain operations (push, at least) fail with
	plink: unknown option "-p"

I've hacked around this problem on my installation by renaming ssh.exe 
to realssh.exe and building ssh.exe from this C source:

     #include <stdio.h>
     #include <unistd.h>

     int main(int argc, char **argv)
     {
         int i;

         for (i = 0; i < argc; i++) {
             if (argv[i][0] == '-' && argv[i][1] == 'p')
                 argv[i][1] = 'P';
         }

         execvp("realssh.exe", argv);
     	return 0;
     }

This works for me, but it's not terribly elegant.  Patching darcs  on 
win32 to supply PuTTY-style command line arguments is probably the 
cleanest solution without dragging in a cygwin dependency (for the real 
ssh.exe).
