This is the "handin" package for Racket, which provides infrastructure for automated handin and checking of programs from within DrRacket. Instructors use this infrastructure to generate a separate, course-specific ".plt" file (or package) that students install.

To install this fork of the handin package, use URL git://github.com/DBatUTuebingen/handin, either through the "Install Package..." menu item in DrRacket's "File" menu, or via

raco pkg install git://github.com/DBatUTuebingen/handin.git

Running the Handin Server

For instructions, after installing, see the "Handin Server" documentation that is added to the Racket documentation.

To run the server on a headless system install packages xvfb, libjpeg8 and libgtk2.0-0 and start the server from within the config directory using:

xvfb-run -a racket -l handin-server

Branching

New code is developed in the master branch, either directly or in topic branches.

• Using merge-staging.sh, you can pull code from master into the deploy-staging branch to test it onto the staging server.
• Using merge-production.sh, you can pull tested code from deploy-staging into the deploy-production branch to run it onto the production server.

No merging happens on the deploy-* branches, they are only forwarded, so that deploy-production is always a non-strict subset of deploy-staging which is a non-strict subset of master.

Please read through merge-staging.sh and merge-production.sh; they are simple scripts to automate repetitive steps, not complex programs which handle well unexpected conditions.
