Code diffs and commit messages from top1000-2000 Java projects in GitHub

This dataset contains pairs <code changes, commit message> from top 1000-2000 Java projects in GitHub via GitHub Developer API.

The structure of files is as follows:

<repository-id>.<repository-name>/ # Each directory contains commits of one project.

&lt;commit-id&gt;.&lt;commit-sha&gt;/ # Each directory contains one commit information, and<br>
# the commit-sha is the primary key of this commit in GitHub. <br>
# The children in this directory have 3 types: the file<br>
# "commit_msg", multiple directories "&lt;filename&gt;", and the file<br>
# "error".

commit_msg # This file contains one line, representing the commit<br>
# message.
&lt;filename&gt;/ # The name of this directory is the changed file name.

patch # The code diffs of this &lt;filename&gt;, describing<br>
# which lines are added and which lines are<br>
# removed with some same lines context.

&lt;filename&gt;/
