Commit Message Guidelines

Short (72 chars or less) summary

More detailed explanatory text. Wrap it to 72 characters. The blank
line separating the summary from the body is critical (unless you omit
the body entirely).

Write your commit message in the imperative: "Fix bug" and not "Fixed
bug" or "Fixes bug." This convention matches up with commit messages

git add . vs git add -A

Both of these will stage all files, including new files (which git commit -a misses) and deleted files.

The difference is that git add -A also stages files in higher directories that still belong to the same git repository. Here's an example:

/my-repo
  .git/
 subfolder/

import SimpleHTTPServer
class CORSHTTPRequestHandler(SimpleHTTPServer.SimpleHTTPRequestHandler):
    def send_head(self):
        """Common code for GET and HEAD commands.

        This sends the response code and MIME headers.

        Return value is either a file object (which has to be copied
        to the outputfile by the caller unless the command was HEAD,
        and must be closed by the caller under all circumstances), or
