RE: CVS commit failure and lock files (under windows with cygwin)

[David Marshburn]

To add a data point to the collected experience of CVS over AFS (a friend
discovered the following):

The cvs.exe binary from the last release of WinCVS (1.2.2a?) works just
fine for me to commit to an AFS-mounted "local" repository (you may recall
that I'd had problems, similar to or the same as Seth, when trying to
commit from a few computers to an AFS-mounted repository).  I just copied
WinCVS' cvs.exe binary over the one in Cygwin's /usr/bin (after making a
backup of the original).  All was dandy after I changed my classpath from
something the Cygwin-CVS expected (/afs/) to what WinCVS-CVS
expected (:local:U:\\).

(I have to credit Mark Foskey with this discovery, who googled on the
problem and came up with my original question :)

cheers,

Re: can't add with wincvs

[Steve Buehler]

Ok.  I was able to get a private key setup and running so that it logs me 
in.  Now I am running into another problem.  I can connect to the 
server.  In fact, in WinCVS, I can even do a create which gives me the 
following reply in WinCVS:
cvs init

*CVS exited normally with code 0*

Now.  When I go again and click on a file to add (testz.php), then click on 
the "Add Selected" button, I get this:
cvs add testz.php (in directory C:\ijobs\cvs\)
cvs add: in directory .:
cvs [add aborted]: *PANIC* administration files missing

*CVS exited normally with code 1*

Is there something else that I have to do to get administration files into 
the directory?  What are the administration files?  As it is, here are the 
files that are in the CVSROOT directory that I am trying to access:
.#checkoutlist  .#rcsinfo   config loginfo,v  taginfo,v
.#commitinfo.#taginfo   config,v   modulesval-tags
.#config.#verifymsg cvswrappersmodules,v  verifymsg
.#cvswrappers   Emptydir/   cvswrappers,v  notify verifymsg,v
.#editinfo  checkoutlisteditinfo   notify,v
.#loginfo   checkoutlist,v  editinfo,v rcsinfo
.#modules   commitinfo  historyrcsinfo,v
.#notifycommitinfo,vloginfotaginfo

Any help would be appreciated.

Thanks
Steve

Yes, but when you log in to the account, you have to enter 
username/password, don't you?  What you need to do is set up plink with a 
key for the account that you wish to log in with.  You will need to 
consult the plink instructions/manual to determine how to do this.  Note 
that you will then need to take appropriate measures to guard that key, 
which will be stored in plaintext in a file on your Windows machine.

The subject of your email implies you have an inkling.

There's a way in SSH2 (I've heard the same can be done
in SSH) to specify one and only one executable per key
to be executed.  Since I haven't done it in a while,
you'll have to consult another source (eg O'Reilly's
SSH book) for the details.

Once you have SSH set up, it's easy:
1. Users execute CVS the same way except their CVSROOT
will specify using ssh.
2. Users who try to use ssh directly will wind up
executing the cvs server.

Noel

CVS, emacs, shh, cygwin

[Seth Copen Goldstein]

I am having trouble using cvs, emacs, bash, etc. on my windows XP machine.
My configuration is:

CVS: Concurrent Versions System (CVS) 1.11 (client/server)
Emacs: GNU Emacs 21.2.1 (i386-msvc-nt5.1.2600)\n of 2002-03-19 on buffy
Cygwin: not sure version, cygwin1.dll is dated: 2/25/2002
Ssh: (from cygwin): OpenSSH_3.2.3p1, SSH protocols 1.5/2.0, OpenSSL
0x0090604f

I have afs (version 1.2.2b), but would also be ok with using SSH.
However:

If I can't set a CVSROOT to :local:f:/path (it complains about path not
being absolute)
I can't set CVS_RSH=SSH, because cvs replies:
cvs [checkout aborted]: end of file from server (consult above messages if
any)

(there are no error messages)

Note: I can't get ssh to work either (it replies: setgid 1: Invalid
argument)

So, I am basically in deep trouble.  Can anyone help.  Thanks.

CVS remembers the root for each working directory in the CVS/Root file
-- you can edit those files as required.  You can also use the -d global
option to override what's in the CVS/Root files, but that's much less
convenient for the long term.

The CVS/Root files in your sandbox(en) need to be updated to reflect the
new repository path. The following will generate a script to do the
conversion:

find . -type d -name CVS \
|awk '{print "echo $CVSROOT >\"" $1 "/Root\""}'

You can tweak the output if need be, then just run the script from the
top of a sandbox. $CVSROOT needs to be set to the new location. Use at
your own risk!

I've only had fair-to-middling success getting WinCVS and SSH to
get along.  But for what it's worth...

When you log in manually with SSH, is it asking you for a
password?  I suspect it is.  The error message looks like SSH's
password prompt.  I'd guess that the ssh client is prompting for
a password, but WinCVS doesn't know how to supply it.

Try generating an SSH key pair, and using ssh-agent (or the local
equivalent) to get things into a state where you can ssh into the
server without typing a password.  Then try WinCVS again.

Obviously, doing that opens up a security hole -- anyone can walk
up to the your Windows box and ssh into the server.  I suspect,
though, that unlike with "cvs login" under pserver, the hole will
close on its own when you log out of Windows, because the
ssh-agent will terminate at that point.  But that's just a guess,
so please *DON'T* take my word for it; test it for yourself!

Depending on your circumstances, that (or working around it by
putting a password on the Windows screen saver) may or may not be
acceptable.

I suggest you read the relevant section of the CVS manual:



The best thing to do is to give every user a login username/password on
the server if they don't already have them and then use the :ext: method
with rsh or ssh -- that doesn't require any configuration on the server
at all.  If you insist on using pserver, the manual tells you what needs
to be done, you just need to figure out how to fit that into whatever it
is that Mandrake has done to make it "easy" for you to set up a server. 
If you can't, that's a Mandrake question, not a CVS question.

Multiple CVSROOT

[Nuno Branco]

I am quite new to CVS and I hope you people can help me with a problem.

I recently found out that (almost) everyone around my company uses CVS
to help with their projects, unfortunately this has become a sysadmin
nightmare to have so many CVS's around my network.

What I am looking for is a way to put several CVSROOT in the same CVS
server. I am currently using mandrake 9.0 which comes with CVS server
installed and a cvs.conf file where i should put the CVSROOT.
Unfortunately for me, I didn't found a way to put more than one CVSROOT
working at a time.

/cvsroot/root1/Project1
/cvsroot/root1/Project4
/cvsroot/root1/Project5
/cvsroot/root2/Project2 
/cvsroot/root3/Project3
... etc

I've been looking trough the ML archives but I didn't found anything
yet.

Could someone share some light?

That's one of the motivations for the CVS client/server protocol -- the
intent was the people should write new clients rather than trying to
wrap the existing command-line client.  Librarifying CVS would likely
require a complete re-write.
