Description

This graph shows how many patches from OpenVZ developers are merged in mainstream, for each kernel version.

It is done in gnuplot. Data set produced by a simple shell script working on git repository.

Source code

Collect data

Here is the script to produce the data for the graph:

#!/bin/sh

latest=$(git tag | grep -v -- -rc | tail -n1 | sed -e 's/^.*\.\(.*\)$/\1/')
((latest++))

get_tag_date() {
        echo $(git show $1 | egrep ^Date: | head -n1) |
                sed 's/^Date: ... \(.*\) [-+]....$/\1/' |
                sed 's/ ..:..:..//' | sed 's/ /-/g'
}

for f in $(seq 13 $latest); do
        v1=v2.6.$((f-1))
        d1=$(get_tag_date $v1)
        if [ $f = $latest ]; then
                v2="HEAD   "
        else
                v2=v2.6.$f
        fi
        d2=$(get_tag_date $v2)
        echo -n $d2 $v2 " "
        git log --pretty=short --no-merges $v1..$v2 | grep 'Author:' | egrep \
                '@openvz.org|@parallels.com|@sw.ru|@swsoft.com|@sw.com.sg|adobriyan@|kuznet@' | wc -l
done | sed 's/ /\t/g'

Draw the graph

Here is the script to produce the graph. Note it calls the previous script under the name 'count'.

#!/bin/sh

if test "$1" != "-f"; then
        git pull
        sh count > time.dat
fi

DATE=$(date '+%d %b %Y')
MAXY=$(awk 'BEGIN {max=0}; ($3 > max) {max=$3}; END {print max+50}' < time.dat)

export GDFONTPATH=/usr/share/fonts/msttcorefonts/
cat << EOF | gnuplot > plot.png
set terminal png transparent nocrop enhanced font verdanab 8 size 600,400

set title "OpenVZ team kernel patches progress as of ${DATE}"

unset xlabel
set xdata time
set timefmt "%b-%d-%Y"
set format x "%b\n%Y"

set yrange [ 0 : ${MAXY} ]
set ylabel "Number of patches accepted into mainstream"

set border 3            # no lines at right and top
set xtics nomirror      # no tics at top
set ytics nomirror      # no tics at right

plot 'time.dat' using 1:3 with linespoints pt 7 ps 1.5 lw 2 lt 2 notitle, \
        ''      using 1:3:2 with labels left offset 0,1 rotate notitle, \
        ''      using 1:3:3 with labels left offset 0.7,0 notitle

EOF
