$http 'GET' memory leak (NOT!)--number of listeners (AngularJS v.1.4.7/8)

[momoadeli]

(issue closed. This is a Chromium feature and not an AJS bug)
(simple example in plunkr: https://plnkr.co/edit/SRRzUUshGYuxhCnw2B33. Screen shot of 'listener leak' in debugger attached below. AngularJS v.1.4.7/8. Chrome Version 47.0.2526.106 (64-bit) )

We are invoking $http GET over a specific $interval (indefinitely). Chrome debugger depicts number of listeners increases 'linearly' over time (perhaps 'xhr' and 'load' listeners). There also seems to be a mild and corresponding JS heap leak which increases with a 'saw tooth' profile although not as prominently as the increase in number of listeners. BTW, we have ruled out $interval as the source of the leaks if that helps.

Simple plunkr included. Please advise.

Many thanks!

Just curious why you closed this, was there a resolution?

@deeg , we believe so. It seems this is a 'feechure' of Chrome dev tools. While recording the timeline, the listeners increase unboundedly (no garbage collection). However between recordings, garbage is collected and listeners drop to 'zero'. NOTE, while recording, if you manually garbage collect, then the listeners indeed drop. It seems, in recording mode, Chrome dev tools requires manual garbage collection. We still have a question to the Chrome team about the heap saw tooth which implies SOME garbage collection. Regardless, this has nothing to do w/AJS at this point. I hope this helps.
