Will Pierce commented on THRIFT-1088:
-------------------------------------
To set up the perf test code, put perftest.py and runtest.sh into trunk/ and
put the patch file THRIFT-1088_python_new_style_classes.patch in the directory
above trunk. Make sure the thrift compiler is in your path, and run
./runtest.sh, which will run perftest.py with the installed python and with
python2.4, then it applies the patch, and re-runs the same tests, then backs
out the patch (with patch -R).
This is just a first stab. I couldn't actually get much of a performance
difference between old/new in the generated code, so I might not be stressing
the differences enough.
Take a look, let me know what you think...

> The included python thrift library classes (TType, TProtocolBase, etc...) are
> all defined using old-style python class definitions. This makes it somewhat
> more difficult to dynamically deal with instances of those classes at
> runtime, since the type() builtin doesn't return the class name. I don't
> think there's really any good reason for avoiding using new style classes.
> The typical fear/uncertainty/doubt with new-style classes (since 2001 when
> they were made available in python 2.2) is that they are thought to be slower
> than old-style classes. I personally haven't ever found the performance
> difference between old and new style classes to
> Unless there's a compelling reason that Thrift developers want to use
> old-style classes, I think it's a more programmer-friendly choice to switch
> these to new-style classes. Not to mention the benefits that new style
> classes provide, see:

> The following thrift classes don't inherit from the 'object' class, so are
