The trouble boils down to firefox. This came up for me when I forgot to comment out a call during some refactoring.

Firefox’s problem

if you want the error, run this code in firefox:

// intentionally chaotic, to mimic a real application in a few lines
larry = function(issue){
  curly(issue) }
curly = function(issue){
  moe(issue) }
moe = function(issue){
  larry(issue) }
tom = function(issue){
  moe(issue) }
dick = function(issue){
  manager(issue) }
harry = function(issue){
  john(issue) }
bob = function(issue){
  harry(issue) }
john = function(issue){
  dick(issue) }
manager = function(issue){
  console.log('resolved issue') }

bob('new issue')
moe('another new issue')

tooooo much recursion

thanks firefox

right about now you might want to start setting breakpoints, but hold tight.

you sed fix it?

sweeping programatic changes are trouble waiting, commit before you try things below.

use sed to make a ghetto call stack:

#!/bin/sed -si -rf
# call me with ./*.js

# scope things -- mostly for readability
/function/{

  # for declarations
  /^ *function/{
    s/^ *function ([[:alpha:]]+) ?\(.*$/&\n\1/
  }

  # for expressions
  /= *function/{
    s/^ *(var )?([^ ]*) =.*$/&\n\2/
  }

  s|^([^\n]*)\n(.*)$|\1\nconsole.log('\2')// fakeCallStack|

}

or a simpler one-liner:

 sed -rsi '/= *function/{ s/^ *(var )?([^ ]*) =.*$/&\nconsole.log("\2")/ }' ./*.js

and your functions start logging themselves!

larry = function(issue){
console.log('larry')// fakeCallStack
  curly(issue) }

fire it up in your browser and logs will go flying by:

tooo much looog

the culprits. Now you’re shooting fish in a barrel.

Search for the functions in your ide of choice or grep -Hnr '<your function name>' ./

chrome gets it right

Chrome logs the call stack for you.

so nice

problem miraculously solved!

but not that miraculous…
