global leak of 'h'

[chrisdew]

I'm trying to use mysql-native with mocha.

Mocha detects global leaks - e.g.

h = 42; // when 'h' has not been declared

instead of

var h = 42;

A typical error is:

1) The engine module "before each" hook:
Error: global leak detected: h

The error always involves 'h'. Does mysql-native use an 'h' without declaring it?

Hard to remember. Easiest way to spot global variable leak is to add property setter, like

global.__defineSetter__('h', function() {
   console.log('property h leak!');
   console.trace();
})
