profilehooks 1.8.1

Decorators for profiling/timing/tracing individual functions

profilehooks

It’s a collection of decorators for profiling functions. E.g. to profile a single function:

from profilehooks import profile

@profile
def my_function(args, etc):
    pass

The results will be printed when the program exits (or you can use @profile(immediate=True)).

If you’re interested in coarse timings and don’t want to pay for the overhead of profiling, use

from profilehooks import timecall

@timecall       # or @timecall(immediate=True)
def my_function(args, etc):
    pass

Finally, you may be interested in seeing line coverage for a single function

from profilehooks import coverage

@coverage
def my_function(args, etc):
    pass

Also functions can be available in Python console or module if run it with -m arg

$ python -m profilehooks
>>> profile
<function profile at 0x1005c6488>

$ python -m profilehooks yourmodule

Full documentation is available through pydoc profilehooks after installation.

The home page for this module is http://mg.pov.lt/profilehooks. It has screensho, uh, that is, more examples.

Changelog

1.8.1 (2015-11-21)

1.8.0 (2015-03-25)

  • New option: @profile(stdout=False) to suppress output to sys.stdout.

1.7.1 (2014-12-02)

  • Make @profile(profiler='hotshot') work again. This was probably broken in 1.0 or 1.1, but nobody complained.
  • Fix missing space in the output of @profile(skip=N).
  • Make @coverage_with_hotshot output match @coverage output precisely.
  • 100% test coverage.
  • Claim Python 3.4 and PyPy compatibility.

1.7 (2013-10-16)

1.6 (2012-06-05)

1.5 (2010-08-13)

  • New argument to @timecall: timer (defaults to time.time). Example: @timecall(timer=time.clock)
  • Better documentation.

1.4 (2009-03-31)

  • Added support for cProfile, make it the default profiler when available. Previously profilehooks supported profile and hotshot only.

1.3 (2008-06-10)

  • Store profile results (when you pass filename to @profile) in pstats format instead of pickles. Contributed by Florian Schulze.

1.2 (2008-03-07)

  • New argument to: @timecall: immediate (defaults to False).
  • Added a test suite.

1.1 (2007-11-07)

  • First release to PyPI, with a setup.py and everything.
  • New arguments to @profile: dirs, sort, entries. Contributed by Hanno Schlichting.
  • Preserve function attributes such as __doc__ and __module__ when decorating them.
  • Pydoc-friendly docstring wrapping and other docstring improvements.

1.0 (2006-12-06)

  • Changed licence from GPL to MIT.
  • New decorator: @timecall
  • New arguments to @profile: skip, filename, immediate.
  • Added support for profile, after becoming convinced hotshot was unreliable. Made it the default profiler.

0.1 (2004-12-30)

  • First public release (it didn’t actually have a version number), announced on my blog: http://mg.pov.lt/blog/profiling.html
  • @profile and @coverage decorators that didn’t accept any arguments.
  • hotshot was the only profiler supported for @profile, while @coverage used trace.py
