# Version 4.1.2

Version 4.1.2 of mod_wsgi can be obtained from:

> https://github.com/GrahamDumpleton/mod_wsgi/archive/4.1.2.tar.gz

## Known Issues

1. The makefiles for building mod_wsgi on Windows are currently broken and need updating. As most new changes relate to mod_wsgi daemon mode, which is not supported under Windows, you should keep using the last available binary for version 3.X on Windows instead.

## Bugs Fixed

1. The integration for Django management command was looking for the wrong name for the admin script to start mod_wsgi express.

2. The code which connected to the mod_wsgi daemon process was passing an incorrect size into the connect() call for the size of the address structure. On some Linux systems this would cause an error similar to:

    (22)Invalid argument: mod_wsgi (pid=22944): Unable to connect to \
        WSGI daemon process 'localhost:8000' on \
        '/tmp/mod_wsgi-localhost:8000:12145/wsgi.22942.0.1.sock'

This issue was only introduced in 4.1.0 and does not affect older versions.

3. The deadlock detection thread could try and acquire the Python GIL after the Python interpreter had been destroyed on Python shutdown resulting in the process crashing. This issue cannot be completely eliminated, but the deadlock thread will now at least check whether the flag indicating process shutdown is happening has been set before trying to acquire the Python GIL.
