Re: Memory Leak with IE7
Hi Eric,
i agree with you about the samples in HelloMaps, but the situation is
quite different: in this case, removing the overlays (marker and
markerClickHandler) does not depend on event but it's periodically
scheduled in a timer. I've tried also with two vector: the first one
is for the markers, the second one is for the markerClickHandler and
then call the removeOverlay with this arguments. The problem in my
opinion are:
-) number of markers, beeing a tracking application, is not knows a
priori
-) the clearOverlays does not free memory with ie7
-) the issue is with the markerClickHandlerVector: in fact, commenting
that, memory does not increase.
As suggested some posts ago, I've recompiled the gwt-user commenting
the opacity attribute in PopUpImplIe6... perhaps quite better, but
however memory usage increases and increases..
any suggestions?
thx,
Michela

Re: Memory Leak with IE7
A Marker is a subclass of Overlay. I have an example in JavaScript
attached to this issue:
http://code.google.com/p/gmaps-api-issues/issues/detail?id=945
There is a GWT binding for the GMap2.removeOverlay() method on the
MapWidget class.
For future reference, many of the methods in the API have example code
in the HelloMaps example, including removing a marker using
removeOverlay().

Re: Memory Leak with IE7
Matas, I've tried recompiling commenting the line in PopUpImplIE6 you
suggest but with no luck :-(
I've seen that declaring a vector of labeledMarker and then adding :
labeledMarkerVector.add(new LabeledMarker(point, options));
removing :
map.clearOverlays();
Iterator v = labeledMarkerVector.iterator
();
while (v.hasNext()) {
//250209Miki: rimuovo anche overlay
singolarmente
map.removeOverlay((LabeledMarker)
v.next());
}
//250209Miki: e poi svuoto vettore di
appoggio
labeledMarkerVector.clear();
is the same thing memory usage still increase. I notice that only
with the vector, without any listener, memory doesn't increase...
the leak seems to be here:
((LabeledMarker) labeledMarkerVector.lastElement()).
addMarkerClickHandler(new MarkerClickHandler() {
public void onClick(MarkerClickEvent event) {
//050209Miki: gestisco qui il popup informativo
InfoWindow info = map.getInfoWindow();
info.open(event.getSender(),
new InfoWindowContent(
""+
//"" +
etc ."
));
}
});
is it a kwonwn issue?
thx

Re: Memory Leak with IE7
Hi eric,
the removeOverlay() you are telling about, is the one from gwt? what
argument do you pass?I've tried having a vector of markers, each time
i put a new marker in... then, after clearOverlays, i've tried with
this:
Iterator v = labeledMarkerVector.iterator();
while(v.hasNext())
{
//250209Miki: rimuovo anche overlay singolarmente
map.removeOverlay((LabeledMarker)v.next());
}
//250209Miki: e poi svuoto vettore di appoggio
labeledMarkerVector.clear();
but with no luck.. I don't undestand what take the removeOverlay
method... and if it could solve the problem
Thx

Re: Memory Leak with IE7
In my tests, an implementation that uses 'removeOverlay()' didn't seem
to leak after running a long time (although it used more memory than
the pool implementation)
The clearOverlays() leak is independent of the GWT wrappers, so about
the best I can say for getting the memory leak resolved is to go to
the issue and 'star' the issue. You can post on the issue or on the
Maps API list about why this is blocking for your application.
Depending on how many icons you have, I think you could work around it
by creating pools of markers by icon, and use some of the LabelMarker
setters to reset the text labels. If there is some functionality you
need, since you have the source to LabeledMarker, maybe there is some
enhancement you could make to it to help add a way to set resources
after the LabeledMarker is constructed.

Re: Memory Leak with IE7
thx eric, the problem is that in gwt i have to instantiate a new
marker object every time i add a marker: in fact it's not possible to
update the "options", but they are defined only in the constructor.So,
how can i solve with this application?is there any patch for google
maps api for gwt?
thx,
Michela

Re: Memory Leak with IE7
hi, Michela, I have similar problem (in different context) with gwt 1.5.3. and IE6/7 memory leaks. After some findings I found that leaking is caused by trasparency filter: style.filter = 'alpha(opacity=0)'; Try to remove transparency effects and then check for memory leaks. Please, take a look at the issue for details: http://code.google.com/p/google-web-toolkit/issues/detail?id=2329&q=popuppanel%20leak#c5 -- Matas --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Memory Leak with IE7
I've been able to reproduce a leak in pure JavaScript without any GWT.
This issue is described in the Maps API issue tracker
http://code.google.com/p/gmaps-api-issues/issues/detail?id=945
I attached some sample JavaScript for creating a pool of markers
instead of removing them from the map.

Re: Memory Leak with IE7
hi all,
I've tried as suggested by jason with this semplified piece of code:
public class MainEntryPoint implements EntryPoint{
private Marker marker;
private MapWidget map;
public MainEntryPoint() {
}
/**
* The entry point method, called automatically by loading a
module
* that declares an implementing class as an entry-point
*/
public void onModuleLoad() {
map = new MapWidget(LatLng.newInstance(38.1890087,
15.5648162), 12);
map.checkResizeAndCenter();
RootPanel.get().add(map);
Timer t = new Timer(){
@Override
public void run() {
for (int i = 0; i < 10; i++)
{
map.clearOverlays();
map.addOverlay(createMarker());
}
}
};
t.scheduleRepeating(3000);
//180209Miki:per prima cosa devo caricare le api
*dinamicamente*
//...poi tutto il resto di conseguenza
//lookupKey(Window.Location.getHost());
}
public Marker createMarker()
{
marker = null;
marker = new Marker(LatLng.newInstance(new Double(15), new
Double(38)));
return marker;
}
}
I would expect memory doesn't increase.. it doesn't
clearOverlays does not remove references with ie7
any workaround...?
please help, thx,

Re: Memory Leak with IE7
commenting the addOverlay, memory usage is costant...
that's why i think there's something wrong with the clearOverlays..

Re: Memory Leak with IE7
Yeah, you are right.
One thing you could try is to comment out the 'addOverlay()' call and
measure your memory again. You won't see anything, but it will tell
you if this is the problem.

but i call the clerOverlays each time i run the timer.. at each loop
the markers should be deallocated... aren't they?

Re: Memory Leak with IE7
Think about what your code is doing here.
You are allocating marker objects and adding them to the map every
time your timer expires.
The map will track these things for you until you call map.removeOverlay().
My guess is that you have hundreds of markers added to the map, all
stacked on top of each other.

Re: Memory Leak with IE7
The engineers at google are very vigilant at avoiding activities that
cause IE to leak, so my first inclination would be to first look at
your third party libs particularly if they perform any manual DOM
manipulation or JSNI. It is rather common on this list to see people
blaming GWT for some bug that later turns out to actually be behavior
of some third party lib.
See if you can't simplify your UI (for testing purposes) so that no
third party libs are needed, and then see what happens with your
memory usage

Hi Jason, yes, reloading page cause memory usage fall out.
My app is quite simple: a gwt ext tab panel, the first tab
showing the
map widget, the second one a gwt ext grid with a few rows (more or
less 10), each one with some information about the markers showed.
I've three "thread", implemented as Timer, which refresh
positions of
markers, informations and last update time. Each thread make a rpc
call and is always running, even when the tab of interest is not

Do you see some critical issue in this application?

Re: Memory Leak with IE7
Hi all, I've found the cause of the memory leak isolating by some
piece of code. It seems not to be caused by gwt-ext but when I make
the map.addOverlay(createMarker(point, myObject));
where createMarker is:
Icon icon = Icon.newInstance(baseIcon);
icon.setImageURL(GWT.getModuleBaseURL()+"images/"+getColor
(nave)+"_ship.png");
GWT.log("Carico immagine "+icon.getImageURL(), null);
LabeledMarkerOptions options = LabeledMarkerOptions.newInstance
();
options.setTitle(nave.getNomeNave());
options.setIcon(icon);
options.setLabelText(String.valueOf(nave.getIdNave()));
options.setLabelClass("labeledMarker");
//200209Miki: se l'id nave è lungo una solo cifra va bene
così...
if((Integer.toString(nave.getIdNave())).length()==1)
options.setLabelOffset(Size.newInstance(1, -26));
//altrimenti devo shiftare la label di due posti a sinistra...
else
options.setLabelOffset(Size.newInstance(-2, -26));
//
LabeledMarker marker = new LabeledMarker(point, options);
((Marker)marker).addMarkerClickHandler(new MarkerClickHandler
() {
public void onClick(MarkerClickEvent event) {
//050209Miki: gestisco qui il popup informativo
InfoWindow info = map.getInfoWindow();
info.open(event.getSender(),
new InfoWindowContent(
"" +

"Localita' Partenza: " +nave.getLocalitaPartenza()
+"" +
"Localita' Arrivo: "+nave.getLocalitaPartenza()+"" //+
//"Merci Pericolose a Bordo: " +
nave.getMerciPericolose()+""
));
}
});
return marker;
It' squite strange but now I'm sure the issue is with this piece of
code..
is map.clearOverlays(); sufficient to deallocate the previous
markers?
thx,

I've tried reloading, I made a mistake some posts ago.. memory
decreases only if the browser is closed and then opened again. Only
reloading causes a bigger increment of memory usage.

Re: Memory Leak with IE7
Hi alex,
sorry but I can't see how fix the number of rows as I'm using a
memoryProxy object.
So, the timer is defined as follows:
Timer t = new Timer() {
public void run() {
getShipInfo();
}
};
where getShipInfo() is
private void getShipInfo() {
MainEntryPoint.getServiceWsNaviInMare().getInfoNaviInMare(new
AsyncCallback() {
public void onFailure(Throwable caught) {
throw new UnsupportedOperationException("Not supported
yet.");
}
public void onSuccess(Object result) {
Vector listaNavi = (Vector) result;
GWT.log("Lista Navi Ricevuta: "+listaNavi.toString(),
null);
if (listaNavi.size()>0) {
Object[][] data = new Object[listaNavi.size()]
[15];
Iterator i = listaNavi.iterator();
int index = 0;
while (i.hasNext()) {
Nave unaNave = (Nave) i.next();
data[index] = new Object[]{
unaNave.getIdNave(), unaNave.getNomeNave
(),
unaNave.getLocalita(), unaNave.getImbarco
(),
etc
GWT.log("Nave "+data[index][0]+data[index]
[1].toString(), null);
index++;
unaNave = null;
}
if (store!=null) {
store.removeAll();
}
MemoryProxy proxy = new MemoryProxy(data);
ArrayReader reader = new ArrayReader(recordDef);
store = new Store(proxy, reader);
store.load();
store.commitChanges();

I've tried with FF and there's no problem...so it's an issue with ie7.
Can you see some big error in the code i posted just above? thx for
help!

Re: Memory Leak with IE7
Assuming adding/removing markers to/from the map is leakless (google probably knows how to do this ;-) we are left with gwt-ext grid. Every 10 sec you remove old rows and add new ones. So you have some DOM- Elements (a table row) that are removed/created every 10 seconds. Probably it's a grid's particular implementation that leaks. But most probably it's just IE that doesn't really remove garbage properly even when it can/should. So what can you do? 1. If it's grid that leaks: dump it - implement smth. yourself with vanilla GWT. 2. It it's IE: let's say the total ammount of markers is never bigger than 25 - you can create 25 rows in the table and instead of adding/ removing them you just change the text. This way you'll have slightly more memory allocated at the beginning but hopefully no leaks while running because no DOM-Elements are created/removed. hth On 24 Feb., 09:14, koalina wrote: > Hi Jason, yes, reloading page cause memory usage fall out. > My app is quite simple: a gwt ext tab panel, the first tab showing the > map widget, the second one a gwt ext grid with a few rows (more or > less 10), each one with some information about the markers showed. > I've three "thread", implemented as Timer, which refresh positions of > markers, informations and last update time.

Re: Memory Leak with IE7
Hi Jason, yes, reloading page cause memory usage fall out. My app is quite simple: a gwt ext tab panel, the first tab showing the map widget, the second one a gwt ext grid with a few rows (more or less 10), each one with some information about the markers showed. I've three "thread", implemented as Timer, which refresh positions of markers, informations and last update time. Each thread make a rpc call and is always running, even when the tab of interest is not active Do you see some critical issue in this application? thx for help, have a nice day Michela On 23 Feb, 20:55, Jason Essington wrote: > Well, I've read various articles claiming that IE leaks like a sieve > (don't have any references for you right now, but I'm sure google > could help). > > One thing to try is does IE's memory usage come down when you reload > the page, or load a new page? > > -jason > > On Feb 23, 2009, at 8:44 AM, koalina wrote: > > > > > is there anyone who knows about memory leaks in this case?I've a > > tabPanel, but tab are not dinamically added, a MapWidget, periodically > > rpc to refresh marker on map > > I'm really getting crazy! > > thx, > > Michela > > > On 23 Feb, 14:37, koalina wrote: > >> I'm using google maps api for gwt, no memory leak found > >> gwt-ext, some leaks found, but it seems not to be my case... > > >> please note that with JScript leaks detect there's no leak found... > >> could it be a problem with ajaxLoader?or perhaps something coming > >> from > >> timer.scheduleRepeating with rpc inside run body? > >> Michela > > >> On 23 Feb, 14:29, Mahavir Jain wrote: > > >>> You should try googling out for memory-leaks for the packages you > >>> are > >>> using.. > > >>> For eg:- If you are using Image bundles then try googling the > >>> memory leaks > >>> related to image bundles.. > > >>> Hope this will help. > > >>> Thanks. > >>> Mahavir > > >>> On Mon, Feb 23, 2009 at 6:49 PM, koalina > >>> wrote: > > it is present web mode running on dedicated tomcat (I don't know > for > hosted mode..). > iexplorer.exe process exponential grows.. > > On 23 Feb, 13:03, Eric Ayers wrote: > > Is this a problem in web mode, hosted mode, or both? > > > On Mon, Feb 23, 2009 at 7:01 AM, koalina > > wrote: > > >> hi Mahavir , > >> thx for your reply. > >> I'm working with gwt 1.5.3 and ie7, is this issue valid also in > >> this > >> case? > >> thx, > >> Michela > > >> On 23 Feb, 12:57, Mahavir Jain wrote: > >>> I am not sure whether this applies to you or not but there is > >>> memory > leak > >>> issue in IE6 browser for all RPC call..

Re: Memory Leak with IE7
Well, I've read various articles claiming that IE leaks like a sieve (don't have any references for you right now, but I'm sure google could help). One thing to try is does IE's memory usage come down when you reload the page, or load a new page? -jason On Feb 23, 2009, at 8:44 AM, koalina wrote: > > is there anyone who knows about memory leaks in this case?I've a > tabPanel, but tab are not dinamically added, a MapWidget, periodically > rpc to refresh marker on map > I'm really getting crazy! > thx, > Michela > > On 23 Feb, 14:37, koalina wrote: >> I'm using google maps api for gwt, no memory leak found >> gwt-ext, some leaks found, but it seems not to be my case... >> >> please note that with JScript leaks detect there's no leak found... >> could it be a problem with ajaxLoader?or perhaps something coming >> from >> timer.scheduleRepeating with rpc inside run body? >> Michela >> >> On 23 Feb, 14:29, Mahavir Jain wrote: >> >>> You should try googling out for memory-leaks for the packages you >>> are >>> using.. >> >>> For eg:- If you are using Image bundles then try googling the >>> memory leaks >>> related to image bundles.. >> >>> Hope this will help. >> >>> Thanks. >>> Mahavir >> >>> On Mon, Feb 23, 2009 at 6:49 PM, koalina >>> wrote: >> it is present web mode running on dedicated tomcat (I don't know for hosted mode..). iexplorer.exe process exponential grows.. >> On 23 Feb, 13:03, Eric Ayers wrote: > Is this a problem in web mode, hosted mode, or both? >> > On Mon, Feb 23, 2009 at 7:01 AM, koalina > wrote: >> >> hi Mahavir , >> thx for your reply. >> I'm working with gwt 1.5.3 and ie7, is this issue valid also in >> this >> case? >> thx, >> Michela >> >> On 23 Feb, 12:57, Mahavir Jain wrote: >>> I am not sure whether this applies to you or not but there is >>> memory leak >>> issue in IE6 browser for all RPC call..

I'm using google maps api for gwt, no memory leak found gwt-ext, some leaks found, but it seems not to be my case... please note that with JScript leaks detect there's no leak found... could it be a problem with ajaxLoader?or perhaps something coming from timer.scheduleRepeating with rpc inside run body?

Re: Memory Leak with IE7
You should try googling out for memory-leaks for the packages you are using.. For eg:- If you are using Image bundles then try googling the memory leaks related to image bundles.. Hope this will help. Thanks.

Re: Memory Leak with IE7
I am not sure whether this applies to you or not but there is memory leak issue in IE6 browser for all RPC call.. You can check the issue on http://code.google.com/p/google-web-toolkit/issues/detail?id=1610.. But this is not case for firefox.. Did you tried on firefox?

Memory Leak with IE7
Hi all, I've developed a gwt app using MapWidget. The markers showed on the map are periodically refreshed via rpc calls. The refresh time period is 10 seconds. The app correctly runs for about an hour, then the memory used increase exponentially... I've installed the js leaks inspector for ie7, but no leak is catched... What can i do to resolve this problem? I've reviewed all code..but everything seems to be correct...
