stevedore 0.10

What is stevedore?

Python makes loading code dynamically easy, allowing you to configure
and extend your application by discovering and loading extensions
(“plugins”) at runtime. Many applications implement their own
library for doing this, using __import__ or
importlib. stevedore avoids creating yet another extension
mechanism by building on top of setuptools entry points. The code
for managing entry points tends to be repetitive, though, so stevedore
provides manager classes for implementing common patterns for using
dynamically loaded extensions.

What’s New?

  • Adds propagate_map_exceptions parameter to all of the extension
    managers which specifies whether exceptions are propagated up
    through the map call or logged and then ignored. The default is to
    preserve the current behavior of logging and ignoring exceptions.
