Memory leak detection

Jeroen Smit — 2012-05-25T11:03:37

Hi,

I am currently looking into some memory leak reports and I am finding the "qx.disposerDebugLevel" very useful.
When looking at the reporting of objects not being disposed (in Object.js, "Missing destruct definition for...") I see several issues about objects in the Qooxdoo framework (I am using V1.4.1):
053884 Missing destruct definition for '$$user_behavior' in qx.ui.table.columnmodel.Resize[undefined]: qx.ui.table.columnmodel.resizebehavior.Default[503]
053885 Missing destruct definition for '$$user_selectionModel' in qx.ui.treevirtual.SelectionManager[undefined]: qx.ui.table.selection.Model[undefined]
053892 Missing destruct definition for '$$user_dataRowRenderer' in webgui.ui.tree.ComtecTree[undefined]: webgui.ui.tree.ComtecTreeRowRenderer[undefined]
053892 Missing destruct definition for '$$user_selectionModel' in webgui.ui.tree.ComtecTree[undefined]: qx.ui.table.selection.Model[undefined]
053893 Missing destruct definition for '$$user_tableModel' in webgui.ui.tree.ComtecTree[undefined]: qx.ui.treevirtual.SimpleTreeDataModel[482]
053893 Missing destruct definition for '$$user_metaColumnCounts' in webgui.ui.tree.ComtecTree[undefined]: 1
053902 Missing destruct definition for '$$user_decorator' in qx.ui.core.Widget[undefined]: qx.ui.decoration.Background[458]
056719 Missing destruct definition for '$$user_tablePaneModel' in qx.ui.table.pane.Scroller[undefined]: qx.ui.table.pane.Model[undefined]
056723 Missing destruct definition for '$$user_menu' in qx.ui.table.columnmenu.Button[undefined]: qx.ui.menu.Menu[616]
056729 Missing destruct definition for '$$user_opener' in qx.ui.menu.Menu[undefined]: qx.ui.table.columnmenu.Button[undefined]
065634 Missing destruct definition for '$$user_toolTip' in qx.ui.toolbar.Button[undefined]: qx.ui.tooltip.ToolTip[473]

Most seem to have to do with classes I derive from, like "qx.ui.table.Table", and where I use the construction with the "custom" argument to call the base-constructor with overrides for the tablePane, selectionModel etcetera. Is there something I should do in the dispose of my own objects? I was expecting code like in "qx.ui.table.Table._applySelectionModel" to dispose any selection model if a new one is set.

Futhermore I have a lot of buttons with a tooltip set using "someWidget. setToolTip(new qx.ui.tooltip.ToolTip("some text"))" and I didn't expect having to dispose them myself. I hope you can tell me how I can fix these issues (if necessary that is).

Thanks in advance.

Best regards,
Jeroen

How to send data to server

Pravin Arote — 2012-05-25T09:41:10

Hi,
 
I want to send data to backend. My current code is

 var rpc = new qx.io.remote.Rpc(
                "http://localhost:56791/Home/AddData",
                "HomeController");
 try {

                      var result = rpc.callSync("AddData", "Pravin");
                      alert(qx.util.Serializer.toJson(person));

                  } catch (e) {
                      alert("Exception :" + e);
                  }


I am perfectly going into AddData method, but no data is getting transfer to
that method.

Can someone help me to pass data?

Inline root missing styling

Loren Schlomer — 2012-05-24T23:16:36

Hello all,

I hope I'm not overlooking something, but I have a problem.

I am working in an Inline application, and the following code adds the
island and the widget to the correct element in the DOM, but it lacks
all styling (only the text is visible), and a null pointer exception
is being thrown:  "Uncaught TypeError: Cannot read property
'appearances' of null"



var content = qx.bom.Selector.query('#content').pop();

var island = new qx.ui.root.Inline(content, true, true);

island.setLayout(new qx.ui.layout.VBox());

var button = new qx.ui.form.Button('Button!');
island.add(button);



Any ideas?


Thank you!

Hi All


My manifest file looks like this

Could someone tell me how to get this info within the application?
I am specifically interested in info.version

Thanks

Question about fixating columns in a table

Jeroen Smit — 2012-05-24T13:00:17

Hi,

I was wondering if it is possible to fixate a column in a table  so when scrolling horizontally all columns up and including to that column stay in place.
Like in Excel for example.

Best regards,
Jeroen

"built" version not acting like "source" version. Parent sub-element not found.

Scott Chapman — 2012-05-23T23:56:53

I think I found a juicy bug!

I filed a bug for this.  http://bugzilla.qooxdoo.org/show_bug.cgi?id=6442

Here's my code snippet, in a handler for a cellClick in a table:
      var handleCellClick = function(e) {
        if (e.getColumn() == 2) {
          var group_task_id = tableModel.getRowData(e.getRow())[0];
          var mainTabs = qx.core.Init.getApplication().getUserData("mainTabs");
          mainTabs.openOrSelectGroupTaskDetailTab(group_task_id);
        }
        if (e.getColumn() == 7) {
          var group_task_id = tableModel.getRowData(e.getRow())[0];
          var req = new qx.io.request.Xhr("/group_task/"+group_task_id);
          req.setMethod("DELETE");
          req.addListener("success", function(e) {
            this.resetSelection();
            this.setFocusedCell();
              var parent = this.getLayoutParent();
              console.log('point a');
              parent.__GroupsQueuedTasksTable.kickReload();
              console.log('point b');
              parent.__GroupsCompletedTasksTable.kickReload();
            }, this);
          req.send();
        }
      };
When I hit the source area, the kickReload between "point a" and "point b"
works fine.
After I do a generate.py build, the kickReload generates an error on the
console:
Uncaught TypeError: Cannot call method 'kickReload' of undefined

This happens on Windows 7 and Ubuntu 10.04 in Firefox 12.0 and Chrome
19.0.1084.46 m.

Am I missing anything?
"It just ain't right!"

Conditional compiles

Connor — 2012-05-23T07:35:29

Hi,

Does qooxdoo support something like conditional compiles ?
If I have for example some debug code, that I don't want to see in my
final build.

(no subject)

Gary Daniels — 2012-05-22T21:03:59

Sorry if this is a dupe. I signed up for the forum but not the mailing list
the first time.

I am writing a fairly large POS-type system to run 24/7 and want to make
sure I have covered all the bases with memory leaks.

I have a few of questions:

1) The "Memory Management" page on the website says:

"be sure to cut all references to the DOM because garbage collection can
not dispose object still connected to the DOM. This is also true for event
listeners for example."

Does this mean I have to manually "removeListener" for every button,
checkbox, etc. that a dialog box uses or are these handled when the widget
is disposed?

2) Is this ok?

this._myContainer = new qx.ui.container.Composite(new qx.ui.layout.Grow())
...
_disposeObjects("_myContainer")

Or do I need:

this._layout=new qx.ui.layout.Grow()
this._myContainer = new qx.ui.container.Composite(this._layout)
...
_disposeObjects("_myContainer","_layout")

3) Should I just assume that every "new" needs a matching "dispose"?

Thanks

Debug source and rpc-server cross-domain trap

Connor — 2012-05-22T07:23:57

Hi,
Usually I test my qooxdoo application with a source build (source-all)
by loading it from a file. This is great because I have uncompressed JS
classes.
Now I've learned that I need to open my application in the same location
(apache) for testing my rpc-calls to avoid cross domain requests. This
seems to cause problem with the source build because classes are not
found by the server:


"NetworkError: 404 Not Found -
http://localhost:8080/source/class/sdxtest/theme/Color.js?nocache=0.6859094274812332"
Color....4812332

Is there a "best practice" for this case ?

Thanks,
Connor

Grid colspan does not allocate space properly

cyrille rigault — 2012-05-22T06:53:22

Hello,


I am using qooxdoo for a while now and I think I found a bug in
colspan for Grids (rowspan seems to be fine).

If you span on 2 columns a widget, its widths is not spread on the 2 columns.

I would like to known if this is a known issue ?

examples (measures are widths)

1)
w1 = 50
w2 = 50
w3 = 200
=> col0 = 200, col1 = 50  OK

      0     1
0 | w1 | w2 |
1 | w3 |      |


2) w3 span on col0 and col1
w1 = 50
w2 = 50
w3 = 200
=> col0 = 50, col1 = 50   PROBLEM

      0     1
0 | w1 | w2 |
1 | w3        |

This can be easily reproducted on the demobrowser with the GridComplex
layout example, using the top grid containing 3 widgets:
left top widget: set width to 50
right top widget : set width to 50
bottom widget : set width to 200, maxwidth to null, colspan to null
=> works fine

now
bottom widget : colspan to 2
=> bottom widget width not spread

PHP RPC-Server seems to work but RPC Console doesnot perform test

Connor — 2012-05-21T14:32:18

Hi,
After setting up a PHP RPC-Server I tried to run the qooxdoo test with
the RPC-Console. The first test
getInteger is executed and results in a log on the RPC Server that does
not show an error.

Server initialized.
Service request: qooxdoo.test.getInteger
Parameters: Array
(

Instantiating service class 'class_test'.

Done.
Computing output took 0.028832912445068 seconds ...
Sending output to client ...

Service request: qooxdoo.test.getInteger
Parameters: Array
(
)

Also the Response on the RPC Console seems to be ok:

{"id":5,"result":1,"error":null}

But the status in the list never changes from "Request is pending..."
and no other test is performed.
Is this a configuration problem ?

qx.io.rest.Resource and POST data

Simon Walter — 2012-05-21T12:18:43

Hi all,

I've used the qx.io.rest.Resource class to GET data from my webservice, 
though I cannot find a method to set the POST data for a POST request. 
How do I do that?

var dataService = {"post": { method: "POST", url: action }};
var dataResource = new qx.io.rest.Resource(dataService);
dataResource.setBaseUrl(this.baseUrl);
//dataResource.setData(data); // How do I do this?
dataResource.post();

Using a qx.ui.basic.Atom as a widget for theUploadMgr

omrihar — 2012-05-21T11:21:23

Hi List,

I'm using the UploadMgr and would like to have an Atom as the upload widget. 
At first I thought simply add a button as well as an Atom, and using the
Atom's click event to trigger the UploadButton.execute() or
UploadButton.press(), but this doesn't work.
Later I realized I can simply use the Atom itself by adding it to the
UploadMgr using the addWidget method.
This works fine. My problem is that I would like to set the Cursor property
of the Atom to "pointer", and once I do that, the UploadMgr somehow
overwrites it and the cursor stays as before.

Did anyone try to do something similar to what I did? Is there a way to
either trigger an execute on the UploadButton or change the cursor of the
Atom?

Thanks!
Omri

problem building rpcconsole

2012-05-21T09:15:33

Hi,

After setting up a php rpc-server I tried to build the rpcconsole
contribution with

generate source


and got an error.


Error: Invalid include block: [u'rpcconsole.demo.Application', u'qx.theme.Modern']

Expression gives no results. Malformed entry: rpcconsole.demo.Application


I've tried the trunk and version 0.3 from the svn. Both have the same
problem. Here is my modified config.json:

{
  "name"    : "RpcConsole",

  "include" :
  [
    {
      "path" : "${QOOXDOO_PATH}/tool/data/config/application.json"
    }
  ],

  "export" :
  [
    "api",
    "build",
    "clean",
    "distclean",
    "fix",
    "inspector",
    "lint",
    "migration",
    "pretty",
    "profiling",
    "source",
    "source-all",
    "test",
    "test-source",
    "translation"
  ],

  "let" :
  {
    "APPLICATION"  : "rpcconsole",
    "APPLICATION_MAIN_CLASS" : "${APPLICATION}.demo.Application",
    "QOOXDOO_PATH" : "W:/Workdir/Komponenten/qooxdoo/qooxdoo-1.6-sdk",
    "QXTHEME"      : "qx.theme.Modern",
    "API_EXCLUDE"  : ["qx.test.*", "rpcconsole.demo.*"],
    "LOCALES"      : [ "en" ],
    "CACHE"        : "${TMPDIR}/cache",    
    "ROOT"         : "."
  }
}


Does anybody know how to build the rpcconsole ?

Thanks,
Connor

destruct definition for qx.io.request.Xhr?

Lance — 2012-05-18T19:48:50

I am trying to ensure that I dispose of objects properly so I am
generating using the disposer config.

One problem I see is that every Xhr prints an error message,
complaining of three fields:

How to clear the selection in a VirtualTree without breaking selection "change" events?

Derrell Lipman — 2012-05-18T15:18:36

When I try to clear the selection in a VirtualTree, it prevents future
selection "change" events from firing. I expect I'm clearing the selection
improperly.
I'm doing tree.setSelection(new qx.data.Array()); Is there a more proper
way to do it?

Here's the playground example which demonstrates that "change" events stop
firing. The log displays, for each click on a tree item, the item name. If
you then click the "Clear selection" button, the selection clears, but any
further click on a tree item selects that item but no longer logs a message.
