The following are examples of js_flowtime.d.
This is a simple script to trace the flow of JavaScript functions.
Here it traces the example program, Code/JavaScript/func_clock.html
C TIME(us) FILE DELTA(us) -- FUNC
0 3650523390654 func_clock.html 2 -> start
0 3650523390721 func_clock.html 67 -> getElementById
0 3650523390773 func_clock.html 51 <- getElementById
0 3650523391609 func_clock.html 835 -> func_a
0 3650523391627 func_clock.html 18 -> getElementById
0 3650523391651 func_clock.html 23 <- getElementById
0 3650523409735 func_clock.html 18084 -> func_b
0 3650523409763 func_clock.html 27 -> getElementById
0 3650523409795 func_clock.html 32 <- getElementById
0 3650523445921 func_clock.html 36125 -> func_c
0 3650523445959 func_clock.html 38 -> getElementById
0 3650523446004 func_clock.html 44 <- getElementById
0 3650523500557 func_clock.html 54552 <- func_c
0 3650523500581 func_clock.html 24 <- func_b
0 3650523500593 func_clock.html 11 <- func_a
0 3650523500648 func_clock.html 54 -> setTimeout
0 3650523500736 func_clock.html 88 <- setTimeout
0 3650523500749 func_clock.html 12 <- start
^C
The fifth column is indented by 2 spaces to show when a new function begins.
This shows which function is calling which.
The TIME(us) column shows time since boot.
The DELTA(us) column shows time from that line to the previous line, and
so can be a bit tricky to read. For example, the second line of data output
shows that a getElementById function happened 67 microseconds after start.
The FILE column shows file that was being executed.
If the output looks shuffled, check the CPU "C" and "TIME" columns, and
post sort based on TIME if necessary.
