Integrate friendly tips from Tor colleagues to make (or not) 4.5 alpha 3;
This includes removal of overloaded (but unused) methods, and addition of
a overlooked call to DataStruct::SetData(nsISupports, uint32_t, bool.)
1 # Uses a binary search algorithm to locate a value in the specified array.
2 window.binary_search = (items, value) ->
4 start = 0
5 stop = items.length - 1
6 pivot = Math.floor (start + stop) / 2
8 while items[pivot] isnt value and start < stop
10 # Adjust the search area.
11 stop = pivot - 1 if value < items[pivot]
12 start = pivot + 1 if value > items[pivot]
14 # Recalculate the pivot.
15 pivot = Math.floor (stop + start) / 2
17 # Make sure we've found the correct value.
18 if items[pivot] is value then pivot else -1
