New submission from Thane Brimhall:
Using the pstats class to print off profiler results is helpful when you want
to filter, order, and limit the number of returned lines. I'd rather see the
most commonly-used subset of pstats functionality included in the profiler's
print_stats implementation directly.
# The current way
pstats.Stats(profiler).strip_dirs().sort_stats('cumulative').reverse_order().print_stats(10)
# Proposed way
profiler.print_stats(strip_dirs=False, sort='cumulative', reverse=True,
limit=10)
Currently only the `sort` kwarg is available. To me this implies that some
level of control was originally intended to be available in the print_stats
method anyway. I also feel like the proposed API is more readable and explicit.
Note that for complex situations you'd still need to use the pstats class
directly, eg. substituting a different stream implementation or
filtering/sorting by multiple values.
This would be a backwards-compatible patch and would be implemented something
like this:
def print_stats(self, sort=-1, limit=None, strip_dirs=True, reverse=True):
import pstats
stats = pstats.Stats(self)
if strip_dirs:
stats = stats.strip_dirs()
stats = stats.sort_stats(sort)
if reverse:
stats = stats.reverse_order()
stats.print_stats(limit)
