<p class="MsoNormal"><span style="font-family:"Arial",sans-serif;color:black">I'm trying to upgrade from GDAL 2.2.0 to 3.0.4 and some of our tests are failing. We're using gdal_array.OpenArray() to create temporary datasets and all the tests where we call band.WriteArray()
are failing with the error "CPLError: Write operation not permitted on dataset opened in read-only mode."<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif;color:black"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif;color:black">I can't see any way to open a gdal_array in update mode, so is this a change in behaviour between 2.2 and 3.0? Should we be able to write to these datasets, or should I change the
failing tests to use the MEM driver instead?<o:p></o:p></span></p>
