Comment 1 e.longuemare 2013-10-24 02:58:39 UTC 
recognition.db was 19.1mo after run a "facetraining" with an empty db (13.3ko).
Now the db is about 38.2mo. Two face have been tagged since training.
Memory load jump, I was able to go in tag manager, and digikam crash with a segfault.

I think it's related to this : https://bugs.kde.org/show_bug.cgi?id=323888 (posts on database grow)
Comment 2 caulier.gilles 2013-10-24 05:25:02 UTC 
Yes, it's a crash in tags manager.

Comment 3 Veaceslav Munteanu 2013-10-24 06:11:58 UTC 
Can you tell me more, about what you did exaclty, because I can't reproduce crash locally, and backtrace doesn't tell me too much, code is ok, I can't even add additional guards...
Comment 4 e.longuemare 2013-10-24 09:13:33 UTC 
I try to reproduce it today, and give you more backtrace and detail.

Thank you,

Eric

Comment 5 caulier.gilles 2013-10-24 09:51:35 UTC 
Veaceslav,

Accordingly with BT; crash is in this code :

int ListItem::row() const
{
    if (d->parentItem)
        return d->parentItem->d->childItems.indexOf(const_cast<ListItem*>(this));

    return 0;
}

I recommend to check the cast of "const_cast<ListItem*>(this)" using dynamic_cast and to check returned value to see if it's null, before to use it with indexOf(). Something like this :

ListItem* const item = dynamic_cast<ListItem*>(this);
if (item)
{
...
}

New crash information added by DrKonqi

digikam (4.0.0-beta1) on KDE Platform 4.11.2 using Qt 4.8.2

- What I was doing when the application crashed:

1 - goto tag manager
2 - click on button add (up to category)
3 - select added category
4 - right clic on category and delete

I have done anythyng else, Digikam crash as soon as delete is clicked

Screen capture - left digikam 3.5.0 - right digikam 4.0.0 beta1 that crash

1 - add a tag to quick access list
2 - delete it (right clic on tag and delete)
3 - digikam crash

PS - i use the two in the same time for tag control (same content of databases but different databases for the two digikam version) -

This one was really hard to debug... after all deleting a item wasn't a good idea since it was still in use... but now it's a memory leak that I don't know how to fix (look for comment  in diffs)

Any ideas?
Comment 9 caulier.gilles 2013-10-30 17:54:22 UTC 
From your comment :

    /** NOTE: trying to delete the item here will cause a crash since
     *  somehow, View still use the old item
     *  Even deleteLater() doesn't help ...
     */
    //item->deleteLater();

Do you identified where item still used and by what ?

Gilles Caulier
Comment 10 caulier.gilles 2013-10-30 18:05:04 UTC 
Are you sure that you have a memory leak. item is QObject based and must be cleaned by Qt and end of digiKam session.

Use valgrind to check, following these intructions:

Comment 11 Veaceslav Munteanu 2013-10-30 18:20:16 UTC 
It was a memory leak before my fix, I added QObject later, It may leak while digikam is active, but I think user won't delete 1 million entries to make a serious leak...
Comment 12 caulier.gilles 2013-10-31 17:14:10 UTC 
Veaceslav,

I checked with valgrind to see if memory leak exists in TagsManager implementation, and i cannot see any report about.

So for me, this file can be closed as solved, if crash has disappear...

Gilles Caulier
Comment 13 Veaceslav Munteanu 2013-11-06 19:01:47 UTC 
Ok, then I will delete that message and close this bug.
