Description wolthera 2019-09-26 13:35:57 UTC
SUMMARY
In an attempt to reproduce https://bugs.kde.org/show_bug.cgi?id=410163 I got this crash.

STEPS TO REPRODUCE
1. Make a file layer
2. Attach a transform mask
3. With transform mask selected, move the file layer.
4. Now select the file layer itself.
5. Move it around a couple of times.

OBSERVED RESULT
Eventually it will crash.

EXPECTED RESULT
That the file layer and the mask get moved somehow. I was trying to see if I could reproduce the outine bug, didn't expect a crash at all.

Comment 1 Halla Rempt 2019-09-28 07:49:45 UTC
This is one for dmitry. The assert happens here:

    void prepareClone(KisPaintDeviceSP src)
    {
        prepareCloneImpl(src, src->m_d->currentData());
        Q_ASSERT(fastBitBltPossible(src));
    }
Comment 2 Halla Rempt 2019-09-28 07:50:21 UTC
It's possible the assert is just broken when layers have been moved since it does:

    bool fastBitBltPossibleImpl(Data *srcData)
    {
        return x() == srcData->x() && y() == srcData->y() &&

The assert is correct, but the entire situation is not :) Moves are usually exclusive, I don't know how it could happen concurrently.

Make sure that fake original() of KisFileLayer has defaultBounds() set

Before KisFileLayer loaded its image (or when the image is not
available), file layer uses a fake paint device. This paint device
should also have proper default bounds set.

Implement KisDefaultBounds::sourceCookie()

It is needed for debugging/sanity-check purposes only. It returns an
abstract pointer to the source object, where default bounds takes its
data from. One can ckeck if the pointer is null or compare two pointers
of different default bounds objects.

Fix crash when moving a layer under a transformation mask

When doing KisPaintDevice::prepareClone(), we should first set
new defaultBounds object, and only after that clone the data.
The reason for this: switching defaultBounds can change current
level-of-detail/frameId, and therefore, switch currentData().
