Subject:	CygWin adding CRs, hurting CVS client/server communications?
Mime-Version:	1.0

Hey folx...currently using OpenSSH under CygWin on an XP box to communicate 
with a CVS server on a Linux box.  Recently upgraded my CygWin installation 
(1.3.22(0.78/3/2), including OpenSSH to v3.6.1p1 (the latest available 
under CygWin), and now CVS client/server communications over SSH 
(CVS_RSH=ssh) don't work.

I've tracked the problem deep enough to suspect that SOMETHING in CygWin 
converts LF to CR+LF line terminators across SSH.  This pretty much hoses 
CVS client/server communications, as the CVS server interprets all incoming 
lines as byte strings including a CR at the end (it treats LF as the actual 
terminator)...especially bad for pathname interpretation, but lots of other 
things may be affected as well.  I've tried altering the CVS server code to 
eat the extra CRs, but too many other things break (including file data 
exchange I'd bet...can't tell which CRs are valid data and which are 
inserted by the system) for that to be effective.

Found a reference in the mailing list archives to a similar problem someone 
was having last October, but the solution was to install a snapshot from 
that time period which seems to be no longer available.  I'm wondering if 
the fix for this issue never found its way into more recent versions of the 
CygWin system components?  I've upgraded CVS on both client and server, but 
based on my testing, I don't think CVS itself is adding the CRs...please 
flame if I'm wrong on that one. <g>  Not sure what else to do right now but 
do without version control for a bit...any better ideas?
