I'm trying to open, manipulate, and save a QGIS project file using a standalone python script. However, upon saving the project, the output file is missing the <mapcanvas> and <legend> XML nodes. Does anyone know why this happens and if it is the expected behaviour or that something else is going on? When these nodes are missing and the project is then served via QGIS server the GetProjectSettings request breaks.
Yes this is indeed expected behavior (although not necessarily very
nice). In QGIS application environment there are various components
that are connected to readProject() and writeProject() signals from
QgsProject and they read/write their own configuration - map canvas is
one of them.
