Subject: Re: CygWin adding CRs, hurting CVS client/server communications?
I've seen the same symptoms...output is garbled because CRs are left in
the strings CVS interprets, and it spits them out after concatenating
them...so you wind up with lines like "textCRtextNL"...I've dumped the
output and confirmed that this is what is happening.
Another good point...I am using the CygWin CVS client, not WinCVS.

I have exactly the same problem as Toscani describes. Last week I did a
routine update on my Cygwin packages, and my Cygwin CVS client (which
worked fine the previous day) could not authenticate with the server any
more. The "login" command works fine, but any subsequent operations fail
to authenticate. Furthermore, the server error message is garbled, as if
a CR/LF problem occurred.
Client: Cygwin on WinXP
Server: Redhat (not sure of the version)
Authentication: Plain pserver, no SSH.
Judging from Patrick's response (who uses WinCVS, and not Cygwin CVS) the
problem lies somewhere in the Cygwin CVS client, not in Cygwin SSH.

Works like a charm here, both for binmode and textmode mounts.
My system: Win2k, WinCVS and Cygwin SSH
The problem mentioned in your mailing list reference was fixed long time ago.
Do your line endings change as well if you scp a textfile from your
client to your server? If yes, then we have indeed an ssh issue on WinXP
platforms. Otherwise your problem must lie somewhere else.

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?
