Python also partially rejects the terms master / slave

Political correctness is taken into account even in programming languages. Last week, Python-developer Victor Stinner (Victor Stinner) from Red Hat sent four pull requests to rename potentially offensive master / slave terms in the documentation and Python code. The author proposed replacing them with socially neutral words that do not offend people whose ancestors were real slaves. As an alternative, there are parent / worker terms.

The proposed change is not a whim of a single developer, but a general trend for different programming languages ​​and technologies. Steener gave examples of similar changes in Redis , Drupal , CouchDB and Django . So, Django and CouchDB have replaced the terms master / slave with leader / follower.

At the same time Steener expressed the opinion that the “slave-owning” terminology can still be left for some terms, such as the master branch in Git, the webmaster and the postmaster.

A heated discussion ensued.

A search in the python / cpython codebase finds numerous inclusions of the “offensive” terms master and slave next to each other, including in the pty and openpty libraries.

For example, here is the Lib / pty.py code :

STDIN_FILENO = 0
STDOUT_FILENO = 1
STDERR_FILENO = 2

CHILD = 0

def openpty():
    """openpty() -> (master_fd, slave_fd)
    Open a pty master/slave pair, using os.openpty() if possible."""

    try:
        return os.openpty()
