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
|
|
|
|
# js_flowtime.d
|
|
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.
