Hi Mathew , 

Thanks for your reply 
I just needed to prevent write operation will taking a backup , could you 
please tell me what would be the risk of taking a repository back while not 
preventing a write to it will the whole repository be corrupted or only the 
files that was being written during backup operation 

Thanks & BRs

It may depend on exactly what you mean by locking a cvs repository.

In most cases it is probably easier to either manually configure existing 
facilities (or write a short shell script to do so), rather than try to find, 
learn, and configure some third party script.

For example:

CVSROOT/commitinfo or other *info hooks might be useful for complex access 
policies.  I may have seen a reference years ago to a third party configurable 
script you can reference from here to make it easier to configure 
branches/directory access, but I don't remember the name...

CVSROOT/config includes a "LockDir", which if defined would allow you to use 
file system permissions (owner, group, mode) to control access at a directory 
level within the main repository, including read-only and/or no access.  [This 
is for temporary locks while CVS is processing a directory; it needs those 
locks even if it is doing a read-only operation...]

If you just want to have a stable version for several operations, maybe just 
use branches and/or tags appropriately?

If you use pserver access, you might be able to temporarily disable all access 
by tweaking a line in an xinetd or inetd config file...

Or temporarily disable all access by altering the permissions on just the top 
level directory of the repository.

P.S.: On a tangent, have you considered upgrading to a newer tool?
Subversion has a similar UI and is often considered somewhat more modern.  
Also, while tools like git and mercurial have a steeper learning curve, they 
are significantly more flexible.  The main reason I haven't gotten around to to 
unsubscribing from this CVS list is that the traffic has dropped to nearly 0...
