Hi Soren

I need to synchronize breakpoints between Eclipse IDE and V8 VM (both sides may
have breakpoints that do not exist on the other side).

Please add a 'UI' for this in the D8 shell.

src/debug-debugger.js:1587: var array = [];
Isn't this missing the breakpoints which are set on functions which has no
associated script? The type 'function' or 'script' should then be present as
well.

I failed to reproduce pure "function" breakpoints. I see that for those
breakpoints that have a script associated with them the breakpoint is
automatically converted to "script" breakpoint.

LGTM

I will look into the function break points, but I think that a function created
from eval might not be converted to a script break point.

I simply tried this:

var FunctionFromEval = eval("(function TTTT() { return 5; })");

then I did:
break FunctionFromEval

I got script breakpoint
