Clojars web interface

This is the source code for the Clojars jar repository. If you're looking for user documentation, try the wiki.

This is only of interest to you if you want to hack on the Clojars source code (send me a pull request with your patches) or if you want to try to run your own copy (for example inside a company).

Running the webapp

  1. Install Leiningen and SQLite3 (Debian: apt-get install sqlite3).

  2. Create an initial sqlite database: mkdir data; sqlite3 data/db < clojars.sql

  3. Run the webapp: lein run 8080 8701

  4. Now try hitting http://localhost:8080/ in your web browser.

If you'd like to run it out of an editor/IDE environment you can probably eval a call to the -main function in src/clojars/core.clj.

Running in a production-like environment (Linux VM)

  1. Install VirtualBox 4.
  2. Install Vagrant by running: gem install vagrant. You may need to install rubygems first.
  3. Run vagrant up and wait, it'll take a while.

Once the virtual machine is up and running you can access the web app at localhost:8088. To ssh into it you can just run vagrant ssh. To push new jars, ssh is forwarded from the local port 2222 so the command is: scp -P 2222 foobar-0.0.1.jar pom.xml clojars@localhost:. You can also ssh directly to port 2222 to the vagrant user, ssh -p 2222 vagrant:localhost, with the password "vagrant".

When something goes wrong, inside the virtual machine, you can find the logs in /var/log/clojar.

Test data

If you'd like to hack on the UI or search it might be useful to have production-like metadata. I've put up a production database dump (with password hashes and email addresses stripped of course) which you can use like this:

rm data/db
zcat clojars-test-data.sql.gz | sqlite3 data/db

If you want all the actual jar files as well you can grab them via rsync.

SSH integration

The SSH integration is kind of a hack and needs improvement. Currently it uses Nailgun but the current setup has threading problems due to the way it does IO.

Basically clojars.scp implements the SCP protocol and acts as a Nailgun "nail" so it can be called from the command-line. Clojars writes an SSH authorized_keys file with a line for each user's public key setting the login command to ng --nailgun-port 8700 clojars.scp USERNAME.

To set it up:

  1. Install the Nailgun ng C program. Just unpack the Nailgun source and run make then copy the ng executable somewhere like /usr/local/bin

  2. Create a "clojars" unix account with a disabled password.

  3. Disable password authentication for that user by adding this to /etc/ssh/sshd_config:

    Match User clojars
    PasswordAuthentication no
  4. Symlink in the auth_keys file the webapp generates:

    cd /home/clojars
    mkdir .ssh
    cd .ssh
    ln -s ...../clojars-web/data/authorized_keys authorized_keys

Mailing lists

There's a public mailing list for general discussion. There's also a separate maintainers list for people looking after the repository and server.

Something went wrong with that request. Please try again.
