Many of the cache operations make use of the default argument to the .get() operation to determine whether the key was found in the cache. The default value of the default argument is None, so this results in these operations assuming that None is not stored in the cache when it actually is. Adding a sentinel object solves this issue. Unfortunately the unmaintained python-memcached library does not support a default argument to .get(), so the previous behavior is preserved for the deprecated MemcachedCache backend. |

The documentation in this tree is in plain text files and can be viewed using any text file viewer. It uses `ReST`_ (reStructuredText), and the `Sphinx`_ documentation system. This allows it to be built into other forms for easier viewing and browsing. To create an HTML version of the docs: * Install Sphinx (using ``python -m pip install Sphinx`` or some other method). * In this docs/ directory, type ``make html`` (or ``make.bat html`` on Windows) at a shell prompt. The documentation in ``_build/html/index.html`` can then be viewed in a web browser. .. _ReST: https://docutils.sourceforge.io/rst.html .. _Sphinx: https://www.sphinx-doc.org/
