Clone all repositories from a user (bitbucket) - API2.0

My post about cloning all bitbucket, originally posted on my old wordpress blog, got some attention over the internet. Well, three or four mentions. Sadly the information in there has been outdated due to Bitbucket’s API changes. That added to the shocking decision by Bitbucket to stop supporting mercurial repos and delete them (!) pushed me to finally download all my repos (again) and eventually move to gitlab. Maybe in a follow up post I will detail how I converted all hg repos to git.

June 1, 2020: users will not be able to use Mercurial features in Bitbucket or via its API and all Mercurial repositories will be removed.

Donwload data for all repositories

The first step is to download as much information as possible to parse from that the download links.

WARNING: if you have more than 100 repositories keep reading.

 USER=username
 PASS=password

# source: https://stackoverflow.com/questions/40429610/bitbucket-clone-all-team-repositories
curl --user $USER:$PASS https://api.bitbucket.org/2.0/repositories/$USER?pagelen=100 > repoinfo.json

With this information at hand we can now extract the ssh link needed to clone the repo. If you only want to clone git repositories, then this or any these solutions will do the trick. However for my use case there are a couple of complications:

  1. repositories are version controlled with either git or hg (that’s how I started);
  2. repositories might have already been cloned in the destination directory;
  3. I have more than 100 repos but the API limits the call to 100 results per page

To address issue number 1, this solution would be enough, but it doesn’t help for #2. So using that answer as starter code, I modified it pull & merge uncommitted changes to previously downloaded repos. This works for me because I am the single developer of those projects and because I only need to donwload the repos in it’s current version as a sort of backup. If this not necessary simply removed the if [ -d "$repo" ] test.

Solving #3 is a bit more complicated, but thankfully someone else came up with a solution. As an aside, this is an example of beauty of making things out in the open: my original post served as an inspiration for this answer, and I am now using it to solve a new problem. We’ve gone full circle.

Now for the code:

cwd=`pwd`
 USER=username
 PASS=password # space to void this getting into history. If there are better options to anonymize the password I would like to know

# source: https://stackoverflow.com/a/51142042
for i in {1..2}; do
	curl --user $USER:$PASS "https://api.bitbucket.org/2.0/repositories/$USER?pagelen=100&page=${i}" > repoinfo.page${i}.json
done

## [0].href will return the https link and [1].href the ssh link
cat repoinfo.*.json | jq -r '.values[] | .links.clone[1].href' > repos.txt

# source: https://stackoverflow.com/questions/40429610/bitbucket-clone-all-team-repositories
for repo in `cat repos.txt`; do
	projectname=`basename ${repo}`
	if [[ $repo == *".git" ]]; then
		echo "It's a git!"
		command="git"
	else
		echo "It's a mercurial!"
		command="hg"
	fi

	if [ -d "$projectname" ]; then
		echo "Project directory exists. $repo will be updated"
		cd $cwd/$projectname
		$command pull
		cd $cwd
	else
		echo "Cloning" $repo
		$command clone $repo
	fi
done

It is possible to refine this code by directly retrieving the information about the type of repo, hg or git, but I don’t have the time to fix what is good enough for my purposes. If anyone wants to go in that direction, this how one can extract that information:

curl --user $USER:$PASS https://api.bitbucket.org/2.0/repositories/$USER?pagelen=100 | jq -r '.values[]  | {scm, links:.links.clone[0].href}'

Pro tip There is a very good website to test interactively jq queries to parse json: website. Very useful.
