[jira] [Created] (CB-8631) Memory leak in
navigator.geolocation.getCurrentPosition
Robert Willett created CB-8631:
----------------------------------
Summary: 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, cordova version reported as 4.1.2
Reporter: Robert Willett
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.
