GitHub and patches

Creating a patch

1. Clone the "semi-official" CPython repo on GitHub:

    $ git clone https://github.com/python/cpython.git
   

2. Change directory to cpython:

    $ cd cpython
   

3. Create and checkout a branch to work on the issue fix:

   $ git checkout -b fix_issue
   

4. Make changes to fix the issue.

5. Commit the changes:

    $ git add file1 file2 file3
    $ git commit -m"Commit message"
    $ git log --pretty=oneline -3
   

6. Create the patch (Note: this creates a patch of the differences between the master branch and the feature branch)

    $ git format-patch master --stdout > fix_issue.patch
   

Testing a patch

$ git apply --stat fix_issue.patch

$ git apply --check fix_issue.patch

Accepting a patch

$ git am --signoff < fix_issue.patch
