Python interface for the 'lsprof' profiler.
Compatible with the 'profile' module.
||Profile(custom_timer=None, time_unit=None, subcalls=True, builtins=True)|
Builds a profiler object using the specified timer function.
The default timer is a fast built-in one based on real time.
For custom timer functions returning integers, time_unit can
be a float specifying a scale (i.e. how long each integer unit
is, in seconds).
- Method resolution order:
Methods defined here:
- dump_stats(self, file)
- print_stats(self, sort=-1)
- run(self, cmd)
- runcall(self, func, *args, **kw)
- # This method is more useful to profile a single function call.
- runctx(self, cmd, globals, locals)
Data descriptors defined here:
- dictionary for instance variables (if defined)
- list of weak references to the object (if defined)
Methods inherited from _lsprof.Profiler:
- x.__init__(...) initializes x; see help(type(x)) for signature
Clear all profiling information collected so far.
Stop collecting profiling information.
- enable(subcalls=True, builtins=True)
Start collecting profiling information.
If 'subcalls' is True, also records for each function
statistics separated according to its current caller.
If 'builtins' is True, records the time spent in
built-in functions separately from their caller.
- getstats() -> list of profiler_entry objects
Return all information collected by the profiler.
Each profiler_entry is a tuple-like object with the
code code object
callcount how many times this was called
reccallcount how many times called recursively
totaltime total time in this entry
inlinetime inline time in this entry (not in subcalls)
calls details of the calls
The calls attribute is either None or a list of
code called code object
callcount how many times this is called
reccallcount how many times this is called recursively
totaltime total time spent in this call
inlinetime inline time (not in further subcalls)
Data and other attributes inherited from _lsprof.Profiler:
- __new__ = <built-in method __new__ of type object>
- T.__new__(S, ...) -> a new object with type S, a subtype of T
- # Backwards compatibility.
- run(statement, filename=None, sort=-1)
- Run statement under profiler optionally saving results in filename
This function takes a single argument that can be passed to the
"exec" statement, and an optional file name. In all cases this
routine attempts to "exec" its first argument and gather profiling
statistics from the execution. If no file name is present, then this
function automatically prints a simple profiling report, sorted by the
standard name string (file/line/function-name) that is presented in
- runctx(statement, globals, locals, filename=None, sort=-1)
- Run statement under profiler, supplying your own globals and locals,
optionally saving results in filename.
statement and filename have the same semantics as profile.run
||__all__ = ['run', 'runctx', 'help', 'Profile']|
