1 The following are examples of js_flowtime.d.
3 This is a simple script to trace the flow of JavaScript functions.
4 Here it traces the example program, Code/JavaScript/func_clock.html
7 C TIME(us) FILE DELTA(us) -- FUNC
8 0 3650523390654 func_clock.html 2 -> start
9 0 3650523390721 func_clock.html 67 -> getElementById
10 0 3650523390773 func_clock.html 51 <- getElementById
11 0 3650523391609 func_clock.html 835 -> func_a
12 0 3650523391627 func_clock.html 18 -> getElementById
13 0 3650523391651 func_clock.html 23 <- getElementById
14 0 3650523409735 func_clock.html 18084 -> func_b
15 0 3650523409763 func_clock.html 27 -> getElementById
16 0 3650523409795 func_clock.html 32 <- getElementById
17 0 3650523445921 func_clock.html 36125 -> func_c
18 0 3650523445959 func_clock.html 38 -> getElementById
19 0 3650523446004 func_clock.html 44 <- getElementById
20 0 3650523500557 func_clock.html 54552 <- func_c
21 0 3650523500581 func_clock.html 24 <- func_b
22 0 3650523500593 func_clock.html 11 <- func_a
23 0 3650523500648 func_clock.html 54 -> setTimeout
24 0 3650523500736 func_clock.html 88 <- setTimeout
25 0 3650523500749 func_clock.html 12 <- start
28 The fifth column is indented by 2 spaces to show when a new function begins.
29 This shows which function is calling which.
31 The TIME(us) column shows time since boot.
33 The DELTA(us) column shows time from that line to the previous line, and
34 so can be a bit tricky to read. For example, the second line of data output
35 shows that a getElementById function happened 67 microseconds after start.
37 The FILE column shows file that was being executed.
39 If the output looks shuffled, check the CPU "C" and "TIME" columns, and
40 post sort based on TIME if necessary.
