CVS via proxy server.

=====================

::

  $ cvs -d:pserver;proxy=$proxyhost;proxyport=$proxyport:$cvsuser@$cvsdomain:/$repo

Create CVS Repository.

======================

::

  $ export CVSROOT=/srv/cvsroot

  $ cvs init

  $ groupadd cvs

  $ useradd -m -g cvs -s /bin/sh -c "CVS Repository"  cvs

  $ chown -R cvs $CVSROOT

  $ chgrp -R cvs $CVSROOT

  $ chmod -R g+s $CVSROOT

  $ grep cvs /etc/services && echo OK

  cvspserver      2401/tcp              # CVS client/server operations

  cvspserver      2401/udp              # CVS client/server operations

  $ echo '# CVS server

  cvspserver  stream  tcp  nowait  root  /usr/bin/cvs cvs --allow-root=/usr/local/src/cvsroot pserver' \

      >/etc/inetd.conf

  $ killall -HUP inetd                  # signal inetd daemon to re-read the config file

  $ ls $CVSROOT/CVSROOT

  readers                   # list of pseudo usernames that can read via cvspserver

  writers                   # list of pseudo usernames can write via cvspserver

  passwd                    # encrypted passwd string with (htpasswd from apache)

CVS workflow.

=============

Check out sources::

  $ cvs co -P $proj

Status of changes::

  $ cvs status

Compare local changes::

  $ cvs diff -u $path

Creating patch::

  $ cvs diff -N -u -r >$patch

History of changes::

  $ cvs log $file

Remove a file::

  $ rm $file            # must first remove it locally

  $ cvs rm $file        # schedules it for removal

Add a file::

  $ cvs add $file

Check in local changes::

  $ cvs ci

Update local sources::

  $ cvs update

Move a file can not be done cleanly at the local level. The best way to do this

with CVS is to go to the cvsroot repository and move the file or directory

within the repository there. The cvsroot repository keeps all files in their RCS

form of filename,v . The next cvs update will manifest the file move.

Tagging sources::

  $ cvs tag $name

  $ cvs rtag $name

Revert file::

  $ rm $file            # remove it from local sources

  $ cvs update $file    # get a new copy from the repository

Working with CVS branches.

==========================

There are no direct command to list symbolic names for branches but this command

allow extract such info::

  $ cd $CVS_PROJ

  $ cvs rlog -l -h -b $(cat CVS/Repository)

Switch to branch::

  $ cvs up -r $BRANCH

Update to HEAD::

  $ cvs up -A

Replace head::

  $ cvs up -j$HEAD -j $NEWBRANCH

Replace branch::

  $ cvs up -j$OLD -j $NEW
