[Qgis-user] [QGIS 3.16] Discovered some glitches with styles and attributes table lengthy fields

[Jésahel Benoist]

Hello list,

I had some strange behaviour when trying to load a layer's default style
from my DB in the properties panel, I got the error "Root <qgis> element
could not be found".

I opened the layers_styles table directly with the attributes table and
discovered that the record's  styleQML got truncated.

The normal length of this field is 69Kb. Truncated is 32Kb. Impossible to
add characters in the table. And modifying style always give a truncated
size around 32Kb.

Strangely, using the style panel to load and save by default works !

By exporting the layer_styles table in a kml file, I see that everything is
correctly stored in the DB.

Btw, the python code I was using to load default style from db is also
broken...

So I think there's some bug in one of the default style loading internal
functions and that the attributes table maximum editable field length is
around 32Kb.

 Am I missing something?

Regards,

Jésahel
