Problems unloading Module

So we have a project that has two states a 'Welcome' state and a 'Module' state.
We have two types of modules. One module is of type TestLab which is a component we've created. The other type of module is a blank view that will show popups as they're called.
The problem we're having is very strange and hard to pin-point.
If we load TestLab A, then unload TestLab A, load TestLab B, unload TestLab B, load TestLab A......all the modules are cleaned up properly.
But if we go from TestLab A, to welcome screen, back to TestLab A....TestLab A will not have unloaded the first time and we'll have double modules, although we're calling the exact same code to unload and load the module.
It's also the same thing if we go from TestLab A -> other module - > TestLab A.
Although if we go to TestLab A -> welcome -> TestLabB -> TestLab A, everything is cleaned up properly.
So it appears in order for a module to be properly unloaded and released from memory, we must load a different module of about the same size.
Anyone have any idea what may be the culprit. It's just very strange to me that modules can be unloaded and released sometimes, while other times they hang in memory depending on what module was loaded after it.

Unfortunately, that isn't my area. I would ask on the FlashBuilder forum.
Did you verify that the preloadSWF entry in mm.cfg looks the same when it
works profiling a simple app?
Also, when you're not attempting to profile, there shouldn't be a preloadSWF
entry in there. Sometimes FB fails to remove that entry so deleting it
might help. FB will re-add the preloadSWF entry as needed.
Another thing to look into is FlashPlayer Trust files. They should be set
up automatically by FB, but occasionally an custom configuration fools the
setup. They are stored in different places based on your OS. Search the
Adobe site for details on where they go. They are typically used to get rid
of security errors when running apps from file://

Problems unloading modules (due to skins?)

Hi,
I have a problem in my Flex application where modules are not unloading. I moved the focus out, cleared out eventlisteners (I read diff. tutorials on that) and now modules are not increasing every time I load them but there is still always 1 instance of the module that has been loaded.
Suppose we have a login module, if I would open it 5 times I would have 5 references in memory, now only 1 which is good, but when the module is not open it needs to be 0 and not 1. When I use the profiler I get 10 paths (this means references still in memory for the login module, right?) to the login module as displayed in the screenshot
It seems to be an issue in the skins or how should I see this? Is it because the skins are used somewhere else in my app also? Can anyone shed some light on this?
Thanks

Which version of flex?

[solved] Unloading modules before suspend to disk

Hi, I'm trying to get my Asus U36jc to suspend to disk and resume. Suspending seems to go fine, but after resuming I get an unresponsive notebook (no response on key presses or ping) showing a black screen. Then immediately the fan gets louder and the notebook gets warmer.
Just before the machine goes to sleep, I see this in my screen:
xhci_hcd 0000:04:00.0: PCI post-resume error -110!
xhci_hcd 0000:04:00.0: HC died; cleaning up
xhci_hcd 0000:04:00.0: HC died; cleaning up
dpm_run_callback(): pci_pm_resume+0x0/0xb0 returns -110
PM: Device 0000:04:00.0 failed to resume async: error -110
hda-codec: out of range cmd 0:20:400:fffff7ff
I found this guide (https://www.kernel.org/doc/Documentatio … ugging.txt) and using that I determined that when I first remove modules ehci_pci, ehci_hcd and xhci_hcd, suspend to disk and resume seem to work fine.
I found out here (https://wiki.archlinux.org/index.php/Pm … end_to_RAM) how to unload modules prior to suspending to RAM, but that doesn't seem to work for suspend to disk, and I can't find how to unload modules prior to that. Can someone tell me how to do that?
Thanks for any help!

I'm not sure if pm-utils is deprecated, it doesn't say so here (https://wiki.archlinux.org/index.php/Pm-utils). In any case its a dependency of upower, which is a dependency of kdelibs, so as long as I want to use KDE my harddrive is stuck with it.
However, I decided to try your suggestion to use systemd:
# asus36JC.service
[Unit]
Description=Script upon suspend/resume
Before=sleep.target
StopWhenUnneeded=no
[Service]
Type=oneshot
RemainAfterExit=yes
ExecStart=/home/diederick/bin/no_modules
ExecStop=/home/diederick/bin/modules
[Install]
WantedBy=sleep.target
It seemed to work perfectly for a couple of times in a row (modules were there before and afterwards) until I restarted the notebook, when the problem was back. But then I remembered to enable the service and now it works. Thanks a lot!

Problem with modules and ModuleLoader

Hi everybody,
i'm facing a real funny problem with modules and
moduleLoader, i hope
it's not (only) my fault anyway...
If i create a normal flex project with fBuilder, i'm able to
use
modules in a lot of different ways (as mxml, as as in a
function etc..)...
but if i try to use them in my fds application (created with
fds
eclipse plugin or as a dataServices project) i can't use
modules. The compile-time error message is
always the same:
Could not resolve <mx:ModuleLoader> to a component
implementation
I tried a lot of solutions, paying attention to import all
the classes, to declaration, naming, positioning
etc...but nothing changes, this thing is drivining me
crazy!!!.
I will appreciate anykind of help.
TIA
Fabio

Any idea?

Problem with module lazy loading in flex 3

Hi every body!
I have some problems with Module lazy loading. I am using flex 3.5, Module-flex3-0.14, parsley 3.2.
I can't get the LazyModuleLoadPolicy working correctly.
In my main application (the one that loads the modules), my parsley context is the following:
        <cairngorm:LazyModuleLoadPolicy objectId="lazyLoadPolicy" type="{ OpenViewMessage }" />
     <cairngorm:ModuleMessageInterceptor type="{ OpenViewMessage }"/>
     <cairngorm:ParsleyModuleDescriptor objectId="test"
          url="TestModule.swf"
          applicationDomain="{ClassInfo.currentDomain}"
     />
And to load my module:
[Inject(id="test")]
[Bindable] public var test:IModuleManager;
<core:LazyModulePod
     id="moduleLoader"
     moduleManager="{test}"
     moduleId="testModule"
/>

            return _viewId;
        [ModuleId]
        public function get moduleId():String
            return _moduleId;
In another flex project, my module context is:

     xmlns:controler="com.cegedim.myit.controler.*">
     <controler:WindowControler/>
</mx:Object>
The module implements IParsleyModule
<mx:Module xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical"

        public function initialize():void
            Alert.show("Module Initialized");
        [MessageHandler(scope="local")]
        public function openViewMessageHandler(message:OpenViewMessage):void
            Alert.show("Opening view " + message.viewId + " in the module " + message.moduleId);
If i uncomment the basicLoadPolicy in LazyModulePod.mxml and remove the lazyModuleLoadPolicy, everything works fine. The module is loaded when it's added to stage and it receives correctly messages dispatched to it. But with the lazy policy the module never loads.
I may have missed something or there is somthing i don't understand because i tried the ModuleTest provided in example in cairngorm sources. It works fine (i mean loading the moduleA2 when receiving a message), but if i replace the change the lazyModulePolicy to listen to broadcasted messages instead of a pingMessage, the module never loads too.
    <cairngorm:LazyModuleLoadPolicy objectId="lazyLoadPolicy" type="{ BroadcastMessage }" />
    <cairngorm:ModuleMessageInterceptor
        type="{ BroadcastMessage }" moduleRef="moduleA" />
public class BroadcastMessage
    public function BroadcastMessage()
If someone has any clue, i'll be happy to test it =)
Thanks.

Hello, back on my issue, i tested a little bit more the message dispaching.
I read the lazyLoadPolicy class and noticed that it always has to have a ModuleId property in the message to work, that's why the broadcast message didn't work to awake the module with the lazy loading policy.
So i added copy of my module:
     <cairngorm:ParsleyModuleDescriptor objectId="test"
          url="TestModule.swf"
          applicationDomain="{ClassInfo.currentDomain}"
     />
     <cairngorm:ParsleyModuleDescriptor objectId="testbis"
          url="TestModuleBis.swf"
          applicationDomain="{ClassInfo.currentDomain}"
     />
Set them both with a basicLoadPolicy, and tries to dispatch a message to only one of them using the ModuleId metatag. I then noticed that both modules received the message and not only the one i expected.
I then changed the ModuleMessageInterceptor configuration to dispatch to only one kind of module:
<cairngorm:ModuleMessageInterceptor type="{ OpenViewMessage }" moduleRef="test"/>
and this worked as expected. Only the first module catched the message. I am obiously messing with the ModuleId metatag but i cannot see what's wrong...
I compiled with
-keep-as3-metadata+=ModuleId
but this hasn't changed anything...

Unloading Modules in Flex

What does the debug trace [Unload SWF] mean?
As per this blog
http://blogs.adobe.com/tomsugden/2010/02/how_to_unload_modules_effectively.html
"This trace indicates that the module have been successfully unloaded"
Is this true?
I am unloading a module, I see the [Unload SWF] trace, but after unloading, if I try to create an object of a class contained in the unloaded module (using reflection), I am still able to create it.
Am I understanding it wrong?
Thanks!

That means that the bytes of the SWF have been removed from memory. I'm not
sure if you're just getting lucky or if there is some other thing going on.

[solved] unload module alx on suspend fails

Hi!
I'm having trouble getting my ethernet card to work properly with suspend to ram (pm-suspend). Its a Qualcomm Atheros AR8161 Gigabit Ethernet Adapter (builtin ethernet-card of the Asus N56VZ) that I'm running with the alx-module that I build from the compat-drivers (compat-drivers-3.9-rc2-2-su, so version 1.2.3 of the alx module) on kernel 3.8.8-2. The driver works fine except it breaks suspend. A first suspend works fine (see suspend.log, upper part), however, after resuming, NetworkManager does not detect a cable being plugged in. Trying to suspend again fails results in the lower part of suspend.log. Removing and probing the module again (reload.log) seems to work fine and resets the whole thing (network works, one suspend works, all following do not work)
Logs see https://gist.github.com/anonymous/5467609
I created a file SUSPEND_MODULES="alx" /etc/pm/config.d/modules (rights 644) that as far as I understand is supposed to unload and load the module upon suspend and resume but for some reason this does not seem to work properly. Why is that, am I just missing a typo? How can I fix it?
Any help is appreciated!

„Sleep hooks
Systemd does not use pm-utils to put the machine to sleep when using systemctl suspend, systemctl hibernate or systemctl hybrid-sleep; pm-utils hooks, including any custom hooks, will not be run. However, systemd provides two similar mechanisms to run custom scripts on these events.” – from wiki, so the sad thing is it's not as easy as in Ubuntu.
But (I guess) it's not impossible. I've got the same problem with ALX so I'm gonna try to make my own hook based on Wiki tips. Currently this Wiki page https://wiki.archlinux.org/index.php/Pm-utilspm is outdated (for Systemd user), so I'll try this section https://wiki.archlinux.org/index.php/Sy … management .

Load/unload modules automatically

Hello guys,
to be able to eject a disk after pressing the eject-button of my cd/dvd drive I have to unload/load the modules manually with the following commands:
rmmod sr_mod
rmmod cdrom
modprobe cdrom lockdoor=0
modprobe sr_mod
After that I can eject it without any problems. I thought I can automatise this by adding options cdrom lockdoor=0 to /etc/modprobe.d/modprobe.conf and finally load the modules in my /etc/rc.conf like the following:
MODULES=([...] "cdrom lockdoor=0" sr_mod)
But it still doesn't work. What's wrong?
Thank you in advance.

Unloading Module Closing Multiple Custom Panels

I have a requirement where in same screen can be openned N times, i have written a custom panel (module loader inside it) with a close buttonn, to load the same module multiple times. The problem is when i close one panel all the panels are closed. The reason it is closing all the panels is i have included the removeChild inside unload tag of the module loader.
I tried changing the "ml.unloadModule();" to "parent.removeChild(this);" then i acheive what is needed close only the panel that is closed, but the module it not unloaded. Is there any way i can acheive closing only a single panel (this is closed) and unload the module.
Below is the custom panel code:
<?xml version="1.0" encoding="utf-8"?>
<s:Panel xmlns:fx="http://ns.adobe.com/mxml/2009"
                     xmlns:s="library://ns.adobe.com/flex/spark"

                              if(parent != null)
                              parent.removeChild(this);
                    </s:unload>
          </s:ModuleLoader>
          <s:Button x="411" y="-23" width="17" height="16" label="Button"
                                click="button1_clickHandler(event)" icon="assets/icon_close_down.png"/>
</s:Panel>

Instead of using an unload handler, just call both unloadModule and removeChild in the click handler.

ValueObjects memory - How can destroy when unload module

The problem is when the app load and unload the same module, the data from callresponder is add to class R5objects. The ask is how can drop, delete, destroy,clean,..... this objects from memory when i unload the module. I try with System.gc () but i don't see change in memory.
If i load and unload the same module many times the application take a lot of memory, the query to database take 500 rows and 10 fields
Thanks
T

valueObjects only is created and used into the module, but when i unload the module valueObjects continue in memory, when i load the same module valueObjects take more and more memory
I thought that when the module was unloaded all its objects are erased, you know how can drop or erase this type of object

[SOLVED] Problem with modules and udev

Hi everybody,
I've been configuring Arch on my new laptop the last few days and today as I was going to perform the first backup, I noticed that my external HDD does not show up in /dev/ when I plug it in. I figured it could be a problem with udev and the fact that in my /etc/rc.conf I use MOD_AUTOLOAD="no" with an explicit list of MODULES generated with hwdetect (as suggested in the wiki).
To "solve" this I just changed MOD_AUTOLOAD to "yes" and after a reboot everything worked fine.
My questions are:
1) Is it possible to keep that feature (udev detects usb drives and creates the corresponding /dev/sdX) while having MOD_AUTOLOAD="no" ? What is/are the appropriate module(s) I have to put in my MODULES array ?
2) What other such "basic" MODULES could be very useful that hwdetect does not tell about.
Sorry for any English mistakes (I'm not a native speaker) and thank you in advance for your help,
yms
Last edited by yms (2010-01-06 12:48:20)

1) Thank you, it works perfectly.
2) Yes I know the question is weird. The thing is I have no precise idea at the moment and I just wanted to know if there are other very widely used features such as the one described in 1) that hwdetect ommits and that has to be loaded in MODULES.
Anyway, thank you very much, I consider this matter [solved]

Apache/2.2.4 (Win32) + Weblogic 8.1 Problem with Module

Hey together,
i'm pretty new to this whole weblogic thing.
I wanted to install the apache plugin for weblogic. I am using weblogic 8.1 and apache 2.2.4 on win xp sp2.
I followed the instructions given in the tutorial at bea.com.
When i try to test the conf-file via httpd.exe -t i get
httpd.exe: Syntax error on line 116 of C:/Programme/Apache Software Foundation/Apache2.2/conf/httpd.conf: Cannot load C:
/Programme/Apache Software Foundation/Apache2.2/modules/mod_wl_20.so into server: Das angegebene Modul wurde nicht gefun
den.
But the mod_wl_20.so file is definitley in this directory as all the other modules.
This is the important part of my httpd.conf:
<IfModule mod_weblogic.c>
<Location /weblogic>
SetHandler weblogic-handler
WebLogicHost localhost
WebLogicPort 7101
MatchExpression *
</Location>
</IfModule>
I even downloaded the latest version of this plugin without sucess. It's all 32 bit, so there should be no problems with that.
I read through several topics/threads dealing with same problems but without success.
Could any1 help please?
Thanks in advance.

Hi,
What do you have on line 116 ? I have it setup on Win2k and it works fine with the following statements. Only difference is that I have Apache 2.0.54 (not 2.2.x)
LoadModule weblogic_module modules/mod_wl_20.so
<Location /wlPortal >
SetHandler weblogic-handler
WebLogicHost localhost
WebLogicPort 7001
</Location>

Around 4 interfaces with this type of error, but all having same problem some messages are failed with this kind of error.
If more messages are attempting to process at the same time in the module processor is there any loading problem that causes this error?.
Thanks & Regards
