unexpected thread total times

GoogleCodeExporter commented 9 years ago

What steps will reproduce the problem?
     time0 = time.time()
     yappi.start()
     <my function>
     stats = yappi.get_stats()
     for stat in stats: print stat
     print "TOTAL TIME:",time.time() - time0

What is the expected output? What do you see instead?
     I expected the TOTAL TIME to be the sum of the total times in each thread.  Instead, I see thread total times exceeding the TOTAL TIME. (i.e. main thread: total time of 147 while global total time is 44 s)

What version of the product are you using? On what operating system?
     yappi 0.54, python2.6.6, linux debian

Yes this is a known problem. This is related with issue 31. thread total times 
are miscalculated when IO blocking functions are used. In current design there 
is no way to calculate this correctly as we have a no way of getting per-thread 
cpu time. However, I have a linux specific branch in the repository(under the 
name: native-perthread) which can calculate total thread times correctly with 
the help of OS and you can compile and use it for your purposes.
