Memory leak - macOSX - leaks command line tool

Post by cocoabsb » Thu May 13, 2021 12:42 am

Hello,
I am developing an application for macOSX with wxWidgets and I would like to understand an issue, as follows:

If I run may application and while it is running I run the macOSX's leaks command line tool, it reports always a very small memory leak and it is always constant as long as I do not run any modules that call neither wxFileDialog(and selects a file) nor wxPrinter(and save as PDF).
If I run a module that calls wxFileDialog(and I select a file) or wxPrinter(and I choose not to print but to save as PDF), then if I run the leaks tools right after one of these operations takes place, "leaks command line tool" reports an increase in memory leaks which increases every time the Application calls wxFileDialog(and selects a file) or wxPrinter(and I choose to save as PDF), otherwise it does not report any increase in leaked bytes).

When I run ps, I can also notice that every time I call wxFileDialog(and select a file) or wxPrinter(and I choose to save as PDF), the amount of memory ps reports for my Application increases, so in fact there must really be a memory leak.

Does anybody know why this happens and how to fix it?

I also noticed that if I run the leaks command line utility and inform as its parameter for instance the "Finder.app" PID, it reports an enormous amount of leaked memory bytes! So, it may be something related to calls to internal system library functions on macOSX.

Thanks for any help on this!

Is it possible that you create these dialogs on the heap and don't free them? Can you show code how and where you use these dialogs?
Use the source, Luke!

No. It is not possible!
My Code:

Code: Select all

    
void <class name>::<method name()>
{
    wxFileDialog *openFileDialog = new wxFileDialog (this, _("Select Import File"), 
        "", "", "", wxFD_OPEN|wxFD_FILE_MUST_EXIST, ptPos);

    // Opens the file dialog itself
    if ( openFileDialog->ShowModal() == wxID_CANCEL ) {
        openFileDialog->Destroy();
        return;     
    }

    m_strFilePath = openFileDialog->GetPath();

    openFileDialog->Destroy();
}    
Every time a I run this code and select a file (click on the Dialog's Open Button), the leaks command tool displays an increased number of memory leaks in my Application and also the ps shows an increased memory usage for my Application.

Here is part of the output (since the whole output is too big and not allowed to be included here) of the leaks command on Finder.app, which is a standard Application developed by Apple and is part of macOSX:

As you can see, I believe that either this tool (leaks) does not a good job (but I believe it does because de ps command also shows that the Application is eating up more memory every time a certain piece of code is run within itself) or the internal libraries on macOSX don´t bother deallocating memory on a regular basis!

Anyone has a different view on this?

Thanks!

Please try to create the dialog on the stack (that's what you're supposed to do, although what you did should work, too), and check if it makes any difference.

If you still get a leak, please run and build the unmodified "dialogs" sample (or any sample that uses a wxFileDialog) and check if it leaks, too. If yes, please open a ticket at http://trac.wxwidgets.org
Use the source, Luke!

Re: Memory leak - macOSX - leaks command line tool

Post by ONEEYEMAN » Thu May 13, 2021 4:05 pm

Hi,
This very well be a OSX library issue or justy a false positive from the "Leaks" tool from Xcode.

To confirm:
If you can build the simple OSX/Cocoa application and run it against this tool it will confirm this..

You may also make a thread on the Apple forum about it and see what Apple developers can say.

But the fact that even the Finder leaks memory is already a good sign that the leaks are false positive. ;-)

Which OSX version are running? And which version of Xcode?

Thank you.

Please try to create the dialog on the stack (that's what you're supposed to do, although what you did should work, too), and check if it makes any difference.

If you still get a leak, please run and build the unmodified "dialogs" sample (or any sample that uses a wxFileDialog) and check if it leaks, too. If yes, please open a ticket at http://trac.wxwidgets.org
I did and I still get the leaks!
Thank you!

Hi,
This very well be a OSX library issue or justy a false positive from the "Leaks" tool from Xcode.

To confirm:
If you can build the simple OSX/Cocoa application and run it against this tool it will confirm this..

You may also make a thread on the Apple forum about it and see what Apple developers can say.

But the fact that even the Finder leaks memory is already a good sign that the leaks are false positive. ;-)

Which OSX version are running? And which version of Xcode?

Thank you.
I am running OSX Mojave (10.14.6) and Xcode Version 11.3.1.

I have already compiled and run the dialogs sample and every time I use the File Operations dialogs the amount of leaked memory increases, so I believe it is an issue related to the macOSX system libraries.

I will make a thread on the Apple forum about it.

Thank you!

Hi,
Are you able to test on any other OSX version?

Thank you.

No. Right now I only have Mojave installed. I will see with a friend that has Big Sur on his iMac if I can test it there.

I have already opened a thread on Apple Developer Forums. Let's see what they say, since the leaks tool reports this big leak when I pass the Finder.app PID as its parameter.

Thank you.
