RE: [flexcoders] repost - Memory leak repeatedly assigning new series to a chart. (2.0b1)

[Jonathan Miranda]

I can tell you after talking with one of the Chart QA team, they know of a memory leak involving resetting the dataprovider of a chart. I had a chart that would refresh every 30 seconds (httpservice connected to an arraycollection for the chart’s dp) that in 4-5 hours would take 95% of your computer’s CPU usage. This is probably something very similar. _________________________________________ Jonathan Miranda Flexible Master of the Web "In the game of chess, it's important to never let your opponent see your pieces."

(2.0b1)   Hello, I'm reposting this because I got no responses last time and I was hoping one of the Flex engineers could confirm that it has been noted (if not verified) that this is happening. This represents a major blocking point to releasing our app. Memory usage CAN NOT continue to grow unbounded. I've narrowed it down to code which cleans up a chart's series array and re-initializes it to add a new set of series with new dataproviders, etc. Note that with only the AddSeries, and SeriesDelete functions removed (all other code including CategoryAxis create/delete, and all XML manipulation remained) there was no leak. I posted a "best practices" question about list cleanup and memory use which describes the architecture I have: http://groups.yahoo.com/group/flexcoders/message/29638?threaded=1 Below is the implementation of DeleteSeries which attempts to remove every series in the chart and clean up the dataProvider in it. Can someone who knows the internal workings of the charts maybe look at this and see if I'm missing something or if there are any known issues with the cleanup of chart series? thanks, Thunder __________________________________ public static function SeriesDelete( thisChart:ChartBase ) {     // try to clean up the series     var i:Number = thisChart.series.length;     while(i--)     {         var obj:Array = thisChart.series.splice(i, 1);         var oSeries:Series = null;         if (obj[0] is Series)         {            oSeries = Series(obj[0]);           if (oSeries.dataProvider is ListCollectionView)           {              var oView:ListCollectionView = ListCollectionView(oSeries.dataProvider);              oView.removeAll();              if (oView.list != null)                 oView.list.removeAll();              oView.release();              delete oView.list;              oView=null;           }           delete oSeries.dataProvider;           oSeries.dataProvider=null;           delete oSeries;           oSeries=null;        }        obj=null;     }     thisChart.series = new Array(); } -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com SPONSORED LINKS Web site design development Computer software development Software design and development Macromedia flex Software development best practice YAHOO!
