Hi All,

Apologies if this is a standard mistake, I'm not very experienced with cron. I'm trying to run cvsimport commands from within a cron job but it always returns:
cvs: Connection refused
Use of uninitialized value in scalar chomp at /usr/bin/git-cvsimport line 349.
Use of uninitialized value in substitution (s///) at /usr/bin/git-cvsimport line 350.
Expected Valid-requests from server, but got: <unknown>

I use ssh keys and have tested that they work by using scp within the script. The script goes as follows:

keychain /var/spool/gitosis/.ssh/id_rsa
. /var/spool/gitosis/.keychain/uname -n-sh

git-cvsimport -d :ext:barrym@cvs:/cvsroot -vio master CVSMODULE

It would also be nice if someone could tell me also how to log the output.

Thanks in advance,
Barry.

I've done this plenty, so it's known to work. Not sure why it's failing in your case.

That's a good start. Have you tried a cvs-over-ssh cvs operation from cron?

Just wrap the commandline in

( $cmd 2>&1) > /tmp/cvsimport.log

HTH, and tell us what the problem was - so the next one to bump into it find the answer in the list ;-)

cheers,

Thanks Martin,

Nice to know how to log the progress! Good tip to try normal cvs over ssh, which works fine.

I wish it was possible to get more verbose output from the git cvsimport command. The connection refused error seems to me to be misleading. I would expect at least some output from cvsps but it doesn't even get to the first step.

So if everything works at the command line, what significant things can be different in a cron job?

I also downgraded to the stable version according to gentoo, so I'm on using 1.5.3.7 now, same result. Unfortunately I might have to give up soon and ask developers to update their own repositories, as it's burning up time.

Will post of course if I find the solution.

Thanks,
Barry.

I've also tried the command like this:

git-cvsimport p --no-cvs-direct -vio master CVSMODULE

Apparently cvsps has it's own client implementation, so I thought I'd disable that in order to be more sure that it was working in the same way as the normal cvs over ssh update that works fine in cron.

The environment! Put "env" in your cron job and compare the output to "env" on the command line. cvs or cvsps may be in $PATH on the command line but not in cron, or $PERL5LIB might be different.

Great suggestion!

I am also having this problem. To debug, I inserted env as you suggested. (Doh, why didn't this occur to me weeks ago?). I compared the output of cron and login-shell runs.

So what is the critical env diff between cron run and login run?

The answer is: CVS_RSH=ssh

Be sure to export.

Thanks.

and perhaps $CVSROOT...
