Number of lines of the source code

Number of lines in the source-code files. Including empty lines and comments.

Source:

  find . -name *.[hcS] -not -regex '\./\.git.*' | xargs cat | wc -l

Number of files

Number of files the kernel consisting of. In contrast to the upper graphic this includes all types of files.

Source:

  find . -type f -not -regex '\./\.git/.*' | wc -l 

Number of lines

Number of lines in the source-code files. Including empty lines and comments.

Increase of lines

Incrementation per day of development:

Source:

  find . -name *.[hcS] -not -regex '\./\.git.*' | xargs cat | wc -l

Number of files

Number of files the kernel consists of. In contrast to the upper graphics (number of lines) this includes all types of files.

Source:

  find . -type f -not -regex '\./\.git/.*' | wc -l 

Number of commits

Source:

  git-log --no-merges --pretty=oneline v2.6.$last..v2.6.$1 | wc -l 

Duration of development

Source:

  date=$(w3m http://www.eu.kernel.org/pub/linux/kernel/v2.6/  | grep linux-2.6.$1.tar.gz | grep -v sign | awk  '{print $2 }')
  dateold=$(w3m http://www.eu.kernel.org/pub/linux/kernel/v2.6/  | grep linux-2.6.$last.tar.gz | grep -v sign | awk  '{print $2 }')
  time1=$(echo `date -d $date +'%j'` - `date -d $dateold +'%j'` | bc)

Number of developers and employers

Source:

  git log -p v2.6.$last..v2.6.$1 | ./gitdm -u -o "$path/stat2.6.$1" 2> /dev/null 1> /dev/null

Diffstat

The Diffstat shows added (red) and deleted (green) lines and the number of changed files (blue).

Source:

  git diff --shortstat v2.6.$last..v2.6.$1

This only deals with Minorreleases (2.6.xx) - Bugfix-Releases (2.6.xx.y) are ignored.

These are different forecasts based on the development of the last versions. I used different models for estimating the developing speed of development.
