How to prevent a Git repository growing above a maximum size?

There is a repository where you need to control its size and in case of exceeding the limit - block any changes. How to implement this?

Solution

  • .git/hooks/pre-receive

    #!/bin/bash

# size limit 2(GB)
sizelimit_gb=2

reposize_kb=`git count-objects -v | grep 'size-pack' | sed  's/.*\(size-pack:\).//'`
let reposize_b=$reposize_kb*1024
let sizelimit_b=$sizelimit_gb*1024*1024*1024

if [ $reposize_b -gt $sizelimit_b ]; then
    echo "Error: repository size > $sizelimit_gb GB"
    exit 1
#else
#    echo "<= $sizelimit_gb GB"
fi

exit 0

    Above script must be saved as .git/hooks/pre-receive in server, with execution permissions enabled (chmod +x .git/hooks/pre-receive).
