b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	26 statprof is intended to be a fairly simple statistical profiler for
b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	27 python. It was ported directly from a statistical profiler for guile,
b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	28 also named statprof, available from guile-lib [0].

b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	31
b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	32 To start profiling, call statprof.start():
b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	33 >>> start()
b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	34
b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	35 Then run whatever it is that you want to profile, for example:
b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	36 >>> import test.pystone; test.pystone.pystones()
b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	37
b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	38 Then stop the profiling and print out the results:
b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	39 >>> stop()
b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	40 >>> display()

b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	51 All of the numerical data is statistically approximate. In the

b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	67 name
b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	68 The name of the procedure.
b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	69
b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	70 By default statprof keeps the data collected from previous runs. If you
b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	71 want to clear the collected data, call reset():
b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	72 >>> reset()
b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	73
b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	74 reset() can also be used to change the sampling frequency from the
b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	75 default of 1000 Hz. For example, to tell statprof to sample 50 times a
b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	76 second:
b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	77 >>> reset(50)
b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	78
b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	79 This means that statprof will sample the call stack after every 1/50 of
b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	80 a second of user + system time spent running on behalf of the python
b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	81 process. When your process is idle (for example, blocking in a read(),
b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	82 as is the case at the listener), the clock does not advance. For this
b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	83 reason statprof is not currently not suitable for profiling io-bound
b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	84 operations.
b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	85
b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	86 The profiler uses the hash of the code object itself to identify the
b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	87 procedures, so it won't confuse different procedures with the same name.
b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	88 They will show up as two different rows in the output.
b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	89
b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	90 Right now the profiler is quite simplistic. I cannot provide
b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	91 call-graphs or other higher level information. What you see in the
b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	92 table is pretty much all there is. Patches are welcome :-)

b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	98 Because signals only get delivered to the main thread in Python,
b032a7b676c6 statprof: vendor statprof.py Gregory Szorc <gregory.szorc@gmail.com> parents: diff changeset	99 statprof only profiles the main thread. However because the time
