will help you Within a PHP class that is part of a much larger system, the full extent of which is not readily known, is it possible to find out where the source code resides for an object that is known to my code? That is, I have a variable that is loaded with an object about which I do not know much. Given that variable, is there a way to know what source file to look in to find the source code for the object that is in my variable? , Sure is. code :
<?php
class Test {
}
$test = new Test;
$reflect = new ReflectionClass(get_class($test));
echo $reflect->getFileName();

 locate corresponding JS source of code which is not optimized by V8

will be helpful for those in need That error message used to be around line 10200 of v8/src/objects.cc, but is no more. It basically means no optimization was currently employed for a particular trace. Possibly because it was unused, or used sufficiently infrequently. It may have likely been a Node.js library function. The address provided is in memory. You'd have to have attached a debugger to v8 and load the symbol for the SharedFunctionInfo at that location. Possibly breakpoint on the line that produces the message too.
I don't think it is that useful to know what was not optimized, as there are lots of things that don't get optimized... just take the output from --trace_opt and assume everything else isn't. It was kind of just a hint that a check was performed for optimized code, and none was there are the time. Maybe try --trace_codegen and work backwards.

Locate the javascript source code from a function using CHrome

will help you You can monitor the event listeners on DOM elements using the Elements tab of the Chrome DevTools; see this documentation. Simply select your element of interest (say, an image) in the DOM tree, and display its event listeners. You can then narrow them down to click, mousedown, mouseup or whatever. Expand these events, and you'll see the JavaScript files that attached listeners on them. You may find what you seek there.
