From 25978542a49e36729ca8f856b9949ec895fe58c0 Mon Sep 17 00:00:00 2001 From: Johan Claesson Date: Mon, 15 May 2017 23:25:13 +0200 Subject: fprof: Sum callers and callees When sampling multiple processes and analyzing with totals true sum together all caller and callee entries which concerns the same function. Previous behaviour was to report each contributing entry. --- lib/tools/src/fprof.erl | 20 +++++++++++++++----- 1 file changed, 15 insertions(+), 5 deletions(-) (limited to 'lib/tools/src') diff --git a/lib/tools/src/fprof.erl b/lib/tools/src/fprof.erl index d1a4624419..436f68d12b 100644 --- a/lib/tools/src/fprof.erl +++ b/lib/tools/src/fprof.erl @@ -2636,22 +2636,32 @@ funcstat_pd(Pid, Func1, Func0, Clocks) -> #funcstat{callers_sum = CallersSum, callers = Callers} = FuncstatCallers -> FuncstatCallers#funcstat{ - callers_sum = clocks_sum(CallersSum, Clocks, Func0), - callers = [Clocks#clocks{id = Func1} | Callers]} - end), + callers_sum = clocks_sum(CallersSum, Clocks, Func0), + callers = insert_call(Clocks, Func1, Callers)} + end), put({Pid, Func1}, case get({Pid, Func1}) of undefined -> - #funcstat{callers_sum = #clocks{id = Func1}, + #funcstat{callers_sum = #clocks{id = Func1}, called_sum = Clocks#clocks{id = Func1}, called = [Clocks#clocks{id = Func0}]}; #funcstat{called_sum = CalledSum, called = Called} = FuncstatCalled -> FuncstatCalled#funcstat{ called_sum = clocks_sum(CalledSum, Clocks, Func1), - called = [Clocks#clocks{id = Func0} | Called]} + called = insert_call(Clocks, Func0, Called)} end). +insert_call(Clocks, Func, ClocksList) -> + insert_call(Clocks, Func, ClocksList, []). + +insert_call(Clocks, Func, [#clocks{id = Func} = C | T], Acc) -> + [clocks_sum(C, Clocks, Func) | T ++ Acc]; +insert_call(Clocks, Func, [H | T], Acc) -> + insert_call(Clocks, Func, T, [H | Acc]); +insert_call(Clocks, Func, [], Acc) -> + [Clocks#clocks{id = Func} | Acc]. + %% Sort a list of funcstat records, -- cgit v1.2.3
