I am trying to track down a file corruption problem that (I think) has
something to do with the interplay of Eclipse, CVS and Cygwin. I have
already sent a message to the Cygwin group, but to no avail. I am not
entirely sure that the problem relates to Eclipse, but I have only noticed
it since using the Eclipse 'Team' feature to share a CVS repository.
I am using the following CygWin config, under Windows XP:
$ uname -a
CYGWIN_NT-5.1 mattspc 1.3.22(0.78/3/2) 2003-03-18 09:20 i686 unknown unknown
Cygwin
$ cvs -version
Concurrent Versions System (CVS) 1.11 (client/server) ...
$ ssh -V
OpenSSH_3.6.1p1, SSH protocols 1.5/2.0, OpenSSL 0x0090702f
$ env | grep CVS
CVSEDITOR=vi
CVSIGNORE=*.dll *.jar *.class *.war .nbattrs tmp CVS CVSROOT .classpath_pre
..classpath_post
CVSROOT=:ext:office:/secure/development/...
CVS_RSH=ssh
$ env | grep CYG
CYGWIN=nontsec nosmbntsec
I recently switched over from using a simple file based cvs repository
(located on a Linux box, shared thru Samba) to use the :ext: method with
ssh. I did this so that I could use the 'team' features of Eclipse and use
CVS through the Eclipse GUI. I also recently upgraded cygwin using the
standard setup.exe update procedure.
One of these things is causing me serious grief in terms of file corruption
for files checked in and out of the cvs repository. I initially thought that
the problem was Eclipse, after seeing a few comments in lists to that
effect, but I have now stopped using it's 'team' features, exclusively using
cvs from the command line, however I
am still getting random corruption of files. I really wish I could isolate
the problem and describe a scenario in which it occurs, but I have not been
able to repeatably get the problem to occur. About the only thing I can pin
down is that I seem to notice the corruption first thing in the morning,
after logging back in.
For example, I will work all day without problems, checking in, updating,
etc, etc, across multiple CVS repositories. I then pack up to go home, close
my machine and reboot. When I get back the next day, log in, and start to
work, I will notice that some of the files that I have had checked out, and
modified, but not checked back in, will have been completely garbled. If I
remove the file, and cvs update, I get a fresh
uncorrupted copy from the repository (as of the last check in). The problem
does not happen for non-repository files.
It is really driving me crazy, because it has caused me to lose work on
several occasions, and I cannot seem to be able to work out precisely what
it causing it so that I can quarantine the tool or process.
Any help would be much appreciated.
Cheers,
M@

The main cause of file corruptions with CVS in Eclipse has been
improperly configured files on the server. If a file contain binary data
it must have a keyword substitution mode of -kb or the client is free to
translate LFs into CRLFs or whatever the platform line ending is. Do the
files being corrupted contain binary data and are they marked as -kb on
the server?

I suspect that you might be right on the Cygwin/SSH front. I've installed
putty, and it works fine, except when I try to actually do anything with
CVS. For example, the following occurs when I do a cvs -n update:
$ cvs -n update
cvs [update aborted]: cannot exec plink -ssh -i
c:/Devel/opt/PuTTY/keys/mfs.PPK: No such file or directory
cvs [update aborted]: end of file from server (consult above messages if
any)
Even though, it appears to work raw:
$ echo $CVS_RSH
plink -ssh -i c:/Devel/opt/PuTTY/keys/mfs.PPK
$ $CVS_RSH -l matts office

Have a lot of fun...
Hmmm ...
