# howto convert a cvs-buildpackage style cvs archive to a tla-buildpackage
# style arch archive
#
# (c) Guido Günther <agx@sigxcpu.org>

apt-get install cscvs tla-buildpackage
# due bug http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=321120
# you have to patch cscvs with this patch:
# http://www.sigxcpu.org/unsorted-patches/cscvs-bad-rlog-parser-no-cookie-fix.diff

#
# Setup of conversion area, needs to be done only once:
#
ROOT=~/cscvs-work # cvs2tla happens here
CVSROOT=/cvs
EMAIL=agx@sigxcpu.org

cd $ROOT
mkdir cvs work arch
tla make-archive $EMAIL--debian $ROOT/arch/debian

#
# This needs to be done for every package you want to convert:
#
PKG=smartmontools # package to convert
ARCHVERSION=$PKG--debian--1.0
LASTUPSTREAM=5.33+5.34cvs20050802 # could be deduced from changelog

mkdir $ROOT/work/$PKG
# get cvs co:
cd $ROOT/cvs
cvs co -d$CVSROOT co -d$PKG debian/$PKG
# add the projekt (category):
cd $_ && tla archive-setup $VERSION
# check with e.g. tla categories, tla branches/versions $PKG
cd $ROOT/work/$PKG
# create working tree
tla init-tree $VERSION
# now use cscvs to import from cvs
cd $ROOT/cvs/$PKG
# create the cache
cscvs cache -b
# import initial revision
cscvs totla -S -i 1 $ROOT/work 
# ...and the rest:
cscvs totla -S -c 2: $ROOT/work 
# TODO: do the same for $PKG--head--1.0 (upstream versions)

# now adjust to tla-buildpackage:
# rsync this into your debian/ arch archive
ARCHROOT=/var/scratch/arch/debian 	# archive
ARCHWORK=/var/scratch/debian/arch/	# working trees

cd $ARCHROOT
rsync -v --progress -a $ANYHOST:$ROOT/debian/$PKG $ARCHROOT

# FIXME: we could do better here and tag all releases
LASTREV=$VERSION-`tla revisions $VERSION | tail -1`
cd $ARCHWORK
mkdir -p $ARCHWORK/+packages/smartmontools
mkdir -p $ARCHWORK/configs/smartmontools
cd $_
tla get $LASTREV smartmontools-$LASTUPSTREAM
cd $_
tbp-markdeb # mark last release

# Done
