> Memory leak in navigator.geolocation.getCurrentPosition
> -------------------------------------------------------
>
> Key: CB-8631
> URL: https://issues.apache.org/jira/browse/CB-8631
> Project: Apache Cordova
> Issue Type: Bug
> Components: Plugin Geolocation
> Affects Versions: 4.0.0
> Environment: Mac - Mavericks 10.9.5, Version 6.1.1 (6A2008a), Cordova 4.1.2. Also same behaviour on Mac Yosemite 10.10.2 , iOS Simulator 8.1, 7.1 and iOS phone 8.1
> Reporter: Robert Willett
> Labels: geolocation, memory-leak
>
> Calling navigator.geolocation.getCurrentPosition appears to leak memory,
> A simple test case with all steps:
> 1. cordova create geolocationtest com.example.geolocation GeoLocation
> 2. cordova plugins add org.apache.cordova.console
> 3. cordova plugin add org.apache.cordova.geolocation
> 4. cordova platform add iOS
> 5. Replace the www/js/index.js with the below below. This is basically the starter code and only two functions have been added, onSuccess and onFailure along with a timer call to navigator.geolocation.getCurrentPosition()
> function onSuccess(position) {
> console.log("Success...");
> }
> function onFailure(error) {
> console.log("Failed...");
> }
> var app = {
> // Application Constructor
> initialize: function() {
> this.bindEvents();
> },
> bindEvents: function() {
> document.addEventListener('deviceready', this.onDeviceReady, false);
> },
> onDeviceReady: function() {
> app.receivedEvent('deviceready');
> setInterval(function () {
> navigator.geolocation.getCurrentPosition(onSuccess , onFailure);
> } , 1000);
> },
> receivedEvent: function(id) {
> var parentElement = document.getElementById(id);
> var listeningElement = parentElement.querySelector('.listening');
> var receivedElement = parentElement.querySelector('.received');
> listeningElement.setAttribute('style', 'display:none;');
> receivedElement.setAttribute('style', 'display:block;');
> console.log('Received Event: ' + id);
> }
> };
> app.initialize();
> 6. cordova build ios
> 7. Run the code in Xcode. The memory footprint keeps climbing as memory from the getCurrentPosition call does not appear to be released.
> 8. Commenting out the console.log entries stills shows the memory footprint climbing around 200K per call to navigator.geolocation.getCurrentPosition().
> The navigator.geolocation.getCurrentPosition call appears to work correctly.
