RunSnakeRun is a small GUI utility that allows
you to view (Python) cProfile or Profile profiler dumps in a sortable
GUI view. It allows you to explore the profiler information using
a "square map" visualization or sortable tables of data.
RunSnakeRun is a simple program, it doesn't provide all the bells-and-whistles of a program like KCacheGrind, it's intended to allow for profiling your Python programs, and just your Python programs. What it does provide:
If you already have Python setuptools installed (a.k.a. easy_install), you should be able to install with:
easy_install RunSnakeRun
easy_install wxPython
As shown, you will require a modern wxPython and Python installation. We don't automatically install this with easy_install, as that can cause problems for those who have manually installed the packages or who are behind corporate firewalls.
You can manually download the package and run:
python setup.py install
to install the package. This will setup a script named "runsnake" on Linux machines which launches the profiler.
To use cProfile to capture your application's profile data:
import cProfile
command = """reactor.run()"""
cProfile.runctx( command, globals(), locals(), filename="OpenGLContext.profile" )
To view the results of your run:
python runsnake.py OpenGLContext.profile
There will be a brief delay as the application is created and begins the loading process, then you should see something like this:
Click on any column title to sort by that property within that list. Select a record in the left-most list view to see a breakdown of that record in the right-side list views. Choose the appropriate view on the right via the tabs. You can resize the borders between the lists and square-map views. You can select a package/module/function hierarchic view via the menus. You can also toggle use of percentage displays there.
RunSnakeRun is reasonably stable. I don't tend to do much work on it, as it tends to just work. My current wish list for the project follows:
If you have an idea, feel free to check out the code and implement the new feature. I'm certainly willing to entertain new features or bug-fix requests as well. The code is available in bzr here:
bzr branch lp:~mcfletch/squaremap/trunk squaremap
bzr branch lp:~mcfletch/runsnakerun/trunk runsnakerun
cd runsnakerun
python setup.py develop
