Notes on CVS Usage

Accessing the repository

The recommended way of accessing the BIND 9 CVS repository is by ssh

to rc.isc.org, using the following environment settings:

CVSROOT=:ext:rc.isc.org:/proj/cvs/isc

CVS_RSH=ssh

Renaming files by respository copy

When you need to rename or move a file that is under CVS control, use

the "repository copy" method as described in the following text

borrowed from an ancient CVS FAQ:

2C.4 How do I rename a file?

CVS does not offer a way to rename a file in a way that CVS can

track later. See Section 4B for more information.

Here is the best way to get the effect of renaming, while

preserving the change log:

1. Copy the RCS (",v") file directly in the Repository.

cp $CVSROOT/<odir>/<ofile>,v $CVSROOT/<ndir>/<nfile>,v

2. Remove the old file using CVS.

By duplicating the file, you will preserve the change

history and the ability to retrieve earlier revisions of the

old file via the "-r <tag/rev>" or "-D <date>" options to

"checkout" and "update".

cd <working-dir>/<odir>

rm <ofile>

cvs remove <ofile>

cvs commit <ofile>

3. Retrieve <newfile> and remove all the Tags from it.

By stripping off all the old Tags, the "checkout -r" and

"update -r" commands won't retrieve revisions Tagged before

the renaming.

cd <working-dir>/<ndir>

cvs update <nfile>

cvs log <nfile> # Save the list of Tags

cvs tag -d <tag1> <nfile>

cvs tag -d <tag2> <nfile>

. . .

This technique can be used to rename files within one directory or

across different directories. You can apply this idea to

directories too, as long as you apply the above to each file and

don't delete the old directory.

Of course, you have to change the build system (e.g. Makefile) in

your <working-dir> to know about the name change.
