Batch-migrating Gitolite repositories to Gogs

NOTE: This will only work if you are an administrator on your Gogs instance, or if an administrator has enabled local repository importing for all users.

First, save the following as migrate.sh somewhere, and make it executable (chmod +x migrate.sh):

HOSTNAME="git.cryto.net"
BASEPATH="/home/git/old-repositories/projects/joepie91"

OWNER_ID="$1"
CSRF=`cat ./cookies.txt | grep _csrf | cut -f 7`

while read REPO; do
	REPONAME=`echo "$REPO" | sed "s/\.git\$//"`
	curl "https://$HOSTNAME/repo/migrate" \
		-b "./cookies.txt" \
		-H 'origin: null' \
		-H 'content-type: application/x-www-form-urlencoded' \
		-H "authority: $HOSTNAME" \
		--data "_csrf=$CSRF" \
		--data-urlencode "clone_addr=$BASEPATH/$REPO" \
		--data-urlencode "uid=$OWNER_ID" \
		--data-urlencode "auth_username=" \
		--data-urlencode "auth_password=" \
		--data-urlencode "repo_name=$REPONAME" \
		--data-urlencode "description=Automatically migrated from Gitolite"
done

Change HOSTNAME to point at your Gogs installation, and BASEPATH to point at the folder where your Gitolite repositories live on the filesystem. It must be the entire base path - the repository names cannot contain slashes!

Now save the Gogs cookies from your browser as cookies.txt, and create a file (eg. repositories.txt) containing all your repository names, each on a new line. It could look something like this:

project1.git
project2.git
project3.git

After that, run the following command:

cat repositories.txt | ./migrate.sh 1

... where you replace 1 with your User ID on your Gogs instance.

Done!
