Description

DT crashes here when opening images.

For now it looks like almost all the crashes happened if the mouse is moving over the drawing area while the image is still loading.

A few backtraces are attached.

this is darktable 2.1.0+161~geedd729

Lock and copy the pipe data in get_point_scale()

It is not safe to use a pipe in a GUI thread. Using a copy in this
case should fix reported crashes see #10881.

I have a version that should avoid this crash. Philipp can you test it?

#7 Updated by Philipp Christ over 3 years ago

Well, the good news is, even with trying for a while, I can no longer reproduce the crash on 3a7c0fba.

The bad news is that now, with orientation active, the position is no longer translated from the correct coordinates. (see screenshot)
The vectors still seem to work in the right direction, just the node coordinates seem to be 90 degrees off.

Also, in all tests so far i have had the odd line/curve like in the attached screenshot, where the affected area would just stay black after drawing and sometimes after opening the image. Zooming/Moving the viewpoint usually fixes this.

Hum... no longer translated, are you sure this has been working at some point?

#9 Updated by Pascal Obry over 3 years ago

Ok, found the issue and fixed it. Can you try again? Thanks.

Everything seems to be in the right place now. Still no crashes either.

#11 Updated by Pascal Obry over 3 years ago

Great! I'm planning for a merge tomorrow. This has been reviewed and tested by different people at this point.

Thanks a lot for the testing and feedbacks. Very much appreciated.
