Based on lsprof (patch #1212837) by Brett Rosen and Ted Czotter. With further editing by Michael Hudson and myself. History in svn repo: http://codespeak.net/svn/user/arigo/hack/misc/lsprof * Module/_lsprof.c is the internal C module, Lib/cProfile.py a wrapper. * pstats.py updated to display cProfile's caller/callee timings if available. * setup.py and NEWS updated. * documentation updates in the profiler section: - explain the differences between the three profilers that we have now - profile and cProfile can use a unified documentation, like (c)Pickle - mention that hotshot is "for specialized usage" now - removed references to the "old profiler" that no longer exists * test updates: - extended test_profile to cover delicate cases like recursion - added tests for the caller/callee displays - added test_cProfile, performing the same tests for cProfile * TO-DO: - cProfile gives a nicer name to built-in, particularly built-in methods, which could be backported to profile. - not tested on Windows recently!

/* "Rotating trees" (Armin Rigo)
|
|
*
|
|
* Google "splay trees" for the general idea.
|
|
*
|
|
* It's a dict-like data structure that works best when accesses are not
|
|
* random, but follow a strong pattern. The one implemented here is for
|
|
* accesses patterns where the same small set of keys is looked up over
|
|
* and over again, and this set of keys evolves slowly over time.
