Description
This graph shows how many patches from OpenVZ developers were merged into mainstream Linux kernel, per each kernel version.
It is drawn by gnuplot using the data set obtained from kernel 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/
