Dozer 0.4 (experimental)

WSGI Middleware version of the CherryPy memory leak debugger

Tracking down memory leaks

Usage:

from dozer import Dozer

# my_wsgi_app is a WSGI application
wsgi_app = Dozer(my_wsgi_app)

Assuming you're serving your application on the localhost at port 5000, you can then load up http://localhost:5000/_dozer/index to view the gc info.

Profiling requests

Usage:

from dozer import Profiler

# my_wsgi_app is a WSGI application
wsgi_app = Profiler(my_wsgi_app)

Assuming you're serving your application on the localhost at port 5000, you can then load up http://localhost:5000/_profiler to view the list of recorded request profiles.

Here's a blog post by Marius Gedminas that contains a longer description of Dozer's profiler.

Inspecting log messages

Usage:

from dozer import Logview

# my_wsgi_app is a WSGI application
wsgi_app = Logview(my_wsgi_app)

Every text/html page served by your application will get some HTML and Javascript injected into the response body listing all logging messages produced by the thread that generated this response.

Here's a blog post by Marius Gedminas that contains a longer description of Dozer's logview.
