Fix Segfault when reaching output image informations before calling Execute()

Julien Osmanrequested to merge
2288-python_segfault into develop

Summary

Testing if the Execute() function has been called before accessing output image information. If not, raise an exception.

Rationale

Fix #2288 (closed)

Implementation Details

Classes and files

The class attribute Application::m_ExecuteDone allows to know if the function Application::Execute has been called. In this MR, we add a test to check this attribute in Application::GetParameterImageBase before returning the output image. If not, an exception is raised, with an explicit message.

Tests

Add a new unit test to check that the following functions raise an exception if called before Execute():

  • Application::GetImageOrigin
  • Application::GetImageSpacing
  • Application::GetImageSize
  • Application::GetImageNbBands
  • Application::PropagateRequestedRegion
  • Application::GetImageRequestedRegion
  • Application::SetImageMetadata
  • Application::GetMetadataDictionary
  • Application::GetImageBasePixelType
