lib_profiling module

Routines for profiling and generation of call graphs (using pycallgrah).

lib_profiling.get_include_functions(input_py, avoid_v=['main'], plus_v=['lib_*'], exclude_v=['*.<module>'], profile_memory=0)

Get str with include argument for pycallgraph.

input_py : str

python script to scan functions in.

avoid_v : list of str

list of funcionts to be excluded.

profile_memory : int

[0 by default] if 1 will include memory profiling information (see notes below).

i_args : str

arguments on functions to be included in pycallgraph profiling.

-Memory profiling (not used by default):

Reported as experimental by pycallgrpah docs. Install psutil and python-psutil, otherwise it will be slow.

lib_profiling.get_pycallgraph_str(i_args, out_png)

Get caller to pycallgraph.

i_args : str

generated wit get_include_functions().

out_png : str

output image (.png).

pycallgraph_str : str

caller.

lib_profiling.process_cprof_file(file_cprof)

Convert cProfile output file into text format, see Script section below for an usage example.
