// IMPORTANT Info for devs who want to add to and/or use debug definitions!
|
|
//
|
|
// MAKING NEW DEBUG DEFS
|
|
// The debug levels are Single Bit Binary Values. i.e, 1,2,4,8,16...
|
|
// In the table below, if you want to define a new value:
|
|
// - If it is debug info ALL devs will often want, then pick one of
|
|
// the remaining "FILLIN" items and give it the name and definition you need
|
|
// - If it is a detail item not often used, simply add yours to the end of the
|
|
// list, multiplying the previous value by 2 to get the the next 'bit' number
|
|
// - In either case, create one or more shortcut/abbreviations in $aDebugShortcuts
|
|
// to make it easy for dev's to specify the new display item.
|
|
//
|
|
// USING DEBUG DEFINITIONS
|
|
// Since these are Bit Values, **never** test using < or > comparisons. Always
|
|
// test using boolean operations, such as
|
|
// if (E107_DBG_PATH)
|
|
// if (E107_DBG_SQLQUERIES | E107_DBG_SQLDETAILS)
|
|
// Since constants are defined for all possible bits, you should never need to use a number value like
|
|
// if (E107_DEBUG_LEVEL & 256)
|
|
// And there's never a reason to use
|
|
// if (E107_DEBUG_LEVEL > 254)
|
|
|
|
if (!defined('e107_INIT')) { exit; }

|

// If no debugging, then E107_DEBUG_LEVEL will be zero
