Original Path: trunk/thuban/test/test_xmlsupport.py
File MIME type: text/x-python
File size: 4112 byte(s) 
* Resources/XML/thuban-0.8.dtd: New DTD for the new file format
version.

* Thuban/Model/save.py (sort_data_stores): New. Make topological
sort of the data sources so they can be written with sources that
data sources that depend on other data sources come after the
sources they depend on.
(SessionSaver.__init__): Add idmap instance variable to map from
objects to the ids used in the file.
(SessionSaver.get_id, SessionSaver.define_id)
(SessionSaver.has_id): New. Methods to manage the idmap
(SessionSaver.write): Use thuban-0.8.dtd
(SessionSaver.write_session): Add a namespace on the session and
write out the data sources before the maps.
(SessionSaver.write_data_containers): New. Write the data
containers.
(SessionSaver.write_layer): Layer elements now refer to a
shapestore and don't contain filenames anymore.

* Thuban/Model/load.py (LoadError): Exception class to raise when
errors in the files are discovered
(SessionLoader.__init__): Define dispatchers for elements with a
thuban-0.8 namespace too.
(SessionLoader.check_attrs): New helper method to check and
convert attributes
(AttrDesc): New. Helper class for SessionLoader.check_attrs
(SessionLoader.start_fileshapesource)
(SessionLoader.start_derivedshapesource)
(SessionLoader.start_filetable, SessionLoader.start_jointable):
Handlers for the new elements in the new fileformat
(SessionLoader.start_layer): Handle the shapestore attribute in
addition to filename.
(SessionLoader.start_table, SessionLoader.end_table): Removed.
They were never used in the old formats and aren't needed for the
new.

* Thuban/Model/session.py (Session.DataContainers): New method to
return all "data containers", i.e. shapestores and tables

* test/xmlsupport.py (SaxEventLister.__init__)
(SaxEventLister.startElementNS, sax_eventlist): Add support to
normalize IDs.

* test/test_xmlsupport.py
(TestEventList.test_even_list_id_normalization): New test case for
id normalization

* test/test_load.py (LoadSessionTest.check_format): Use ID
normalization
(LoadSessionTest.thubanids, LoadSessionTest.thubanidrefs): New
class atrributes used for ID normalization
(TestSingleLayer, TestLayerVisibility, TestLabels.test)
(TestLayerProjection.test, TestRasterLayer.test): Adapt to new
file format
(TestJoinedTable): New test for loading sessions with joined
tables.
(TestLoadError): New. Test whether missing required attributes
cause a LoadError.

* test/test_save.py (SaveSessionTest.thubanids)
(SaveSessionTest.thubanidrefs): New class attributes for ID
normalization in .thuban files.
(SaveSessionTest.compare_xml): Use id-normalization.
(SaveSessionTest.testEmptySession)
(SaveSessionTest.testLayerProjection)
(SaveSessionTest.testRasterLayer)
(SaveSessionTest.testClassifiedLayer): Adapt to new file format.
(SaveSessionTest.testLayerProjection): The filename used was the
same as for testSingleLayer. Use a different one.
(SaveSessionTest.test_dbf_table)
(SaveSessionTest.test_joined_table): New test cases for saving the
new data sources structures.
(TestStoreSort, MockDataStore): Classes to test the sorting of the
data stores for writing.
