Notes

This release of the Python agent adds support for the Cornice REST component library for the Pyramid web framework, as well as a number of minor feature improvements and bug fixes.

The agent can be installed using easy_install/pip/distribute via the Python Package Index or can be downloaded directly from our download site.

For a list of known issues with the Python agent see our online help article on the status of the Python agent.

New Features:

  • Instrumentation added for the Cornice REST component library for the Pyramid web framework.

Bug fixes/Improvements:

  • Enhance the instrumentation for the Bottle web framework to work around the problem that the Bottle framework was not using 'functools.wraps()' correctly in the implementation of its 'auth_basic()' decorator. This was resulting in the web transaction being named after the 'wrapper' function closure used in the implementation of the decorator rather than the wrapped request handler the decorator was applied to. A pull request was made against the Bottle framework and the change will be included in a future version of Bottle. Our change ensures that the correct result is also obtained with older Bottle versions.

  • When using the database connection object created by the sqlite3 database client module as a context manager, the automatic rollback or commit performed by the context manager when the scope of the context manager is exited, will now be tracked.

  • If a function trace was applied to the bound method of a class implemented in a C extension module, the name of the module shown in the name of the function was being wrongly designated as the Python 'builtins' module.

  • Updated memcache instrumentation wrappers to use our latest function wrapper implementation. Our latest function wrappers better preserve the ability to introspect wrapped functions/methods and so return the same result as one would expect if no wrapper had been applied.
