[Bug 209225] New: Crash when running batch queue in background

https://bugs.kde.org/show_bug.cgi?id=209225



           Summary: Crash when running batch queue in background

           Product: digikam

           Version: unspecified

          Platform: SuSE RPMs

        OS/Version: Linux

            Status: UNCONFIRMED

          Severity: crash

          Priority: NOR

         Component: general

        AssignedTo: [hidden email]

        ReportedBy: [hidden email]





Version:            (using KDE 4.2.4)

OS:                Linux

Installed from:    SuSE RPMs



Hi,



I've added about 200 tif-files to a new batch queue.

I've assigned three tools:

1) resize to 1600px

2) simple sharp 10%

3) convert to jpg with 90%



After starting the process I put the batch queue manager window in the

background. A while later digikam crashes. The crash is not related to a

certain file or number of images in the queue. It occurs most of the time at a

random time. A high number of images in the queue does increase the possibility

of a crash, of course.



Here is the crash log:

Mh, weird, the backtrace has two KCrash handlers
Anyways they seem to be Qt4 related issues. - What is your Qt4 version ?
Thanks

Thread 2 is the problem: Accessing a widget must never happen from non-UI
thread!
Gilles, is this a single bug or are more parts of BQM affected?

Marcel,

I have see the pb in trace, but if i remember, tool settings is passed from GUI
threads to tool thread using a simple container... Look BatchToolSet class...

The ActionThread calls BatchTool::setSettings from the thread.
From there assignSettings2Widget() is called. The name of this method implies
that a widget is accessed.
Which is the best way to solve this:
1) Changing a widget is not needed at all when called from the thread - remove
the call from setSettings() and add this call where appropriate
2) Changing the widget is necessary - emit a signal to a slot
assignSettings2Widget().

Right. The solution 2/ sound like the best for me...

Marcel,

If i use BatchTool::signalSettingsChanged(const BatchToolSettings&) and connect
it to new pure virtual void BatchTool::slotAssignSettings2Widget(const
BatchToolSettings&), will be enough ?

Of course, if this case, BatchTool::assignSettings2Widget() method is removed
everywhere, and not called from batch thread...

Yes this looks good. I've done now about a thousand files in a few batch tool
runs without a crash. Tried to minimize the window, put it in background, doing
editing in parallel - everything is stable.

Thanks,
Guenther
