3            * Thuban/UI/identifyview.py (IdentifyView.__init__):
4            Use ListCtrl instead of GridCtrl
5

13    
14            Do not cache the values returned by the tree widget's
15            GetFirstChild and GetNextChild methods because it led to lots of
16            segfaults. The new way requires more brute force but is more
17            reliable.
18    
19            * Thuban/UI/legend.py (LegendTree.__init__): Remove instance
20            variable layer2id
21            (LegendTree.find_layer): New method to do with brute force what
22            layer2id tried to accomplish
23            (LegendTree._OnMsgLayerChanged)
24            (LegendTree._OnMsgLayerTitleChanged, LegendTree.__ShowHideLayer):
25            Use find_layer instead of layer2id
26            (LegendTree.__RemoveLayer, LegendTree.__AddLayer): No need to

28            (LegendTree._OnMsgMapLayersRemoved)
29            (LegendTree._OnMsgMapLayersAdded): Get by without layer2id.
30

36    
37            * Thuban/UI/mainwindow.py (layer_rename command, table_rename command):
38            New commands.
39            (main_menu): Add the new commands.
40            (MainWindow.TableRename): New. Implementation of the table_rename
41            command.

43            command.
44    
45            * Thuban/Model/session.py (Session.AddTable): call self.changed to
46            set the modified flag

52            instead of issue so that the modified flags get updated.
53    
54            * test/test_base.py (SomeTitledObject): Derive from Modifiable
55            instead of Publisher to reflect reality better and to accomodate
56            the fact that SetTitle now calls changed instead of issue
57    
58    2003-06-02  Bernhard Herzog  <[email protected]>
59    
60            * Thuban/UI/classgen.py (GenQuantilesPanel.GetList): Resource
61            acquisition has to happen before the try in a try-finally.
62    
63    2003-06-02  Bernhard Herzog  <[email protected]>
64    
65            * Thuban/UI/legend.py (LegendTree._OnMsgMapLayersRemoved): It's
66            possible that a layer is removed that is not currently selected in
67            the legend so don't check for this.
68    
69    2003-05-30  Bernhard Herzog  <[email protected]>
70    
71            * Thuban/Model/layer.py (Layer.Destroy): Set all instance
72            variables to None that have direct or indirect references to

87            selection by selecting the layer item even if the user clicked on
88            the classification.

90            around a bug in wx which doesn't keep track of the selection
91            properly when subtrees are deleted.

113            RTBug #1904.
114    
115            * Thuban/UI/classifier.py: Remove unused import of ClassGenerator.
116    
117            * Thuban/UI/legend.py: The legend was cleared and repopulated any
118            time something changed which caused some state to be lost such
119            as which children were expanded or collapsed. Fixes RTBug #1901.
120            (LegendTree._OnMsgMapLayersAdded): Add only new layers.

129            and call __RemoveLayer.
130            (LegendTree.__AddLayer): New. Add a new layer to the legend.
131            (LegendTree.__RemoveLayer): Remove a layer from the legend.
132            (LegendTree.DeleteChildren): New, overrides wxTreeCtrl method.
133            Should only be called with the id of a layer branch.
134            (LegendTree.GetRootItem): New, overrides wxTreeCtrl method.
135            Returns the root item or creates one if necessary.
136

146            simply center it on the display. Fixes RTBug #1849.
147    
148            * extensions/thuban/gdalwarp.cpp: Removed code that allowed gdalwarp
149            to be compiled as a standalone app. Now the code can only be
150            called from Python which simplifies the parameter passing.
151            (ProjectRasterFile): Handle Python arguments. Remove code that
152            checks for a destination dataset. Add more clean up code.
153    
154            * test/test_map.py (TestMapWithContents.test_raise_layer_top,
155            TestMapWithContents.test_lower_layer_bottom):

377            * Thuban/Model/transientdb.py (TransientTableBase.Width):Use a

481            The latter implements the selection GUI without dependency on a layer.
482            LayerTableFrame now is derived from QueryTableFrame and connects
483            to a layer.
484    
485            * Thuban/UI/mainwindow.py (MainWindow.TableShow): A very coarse
486            implementation that still needs work.

528            Typo fixed.
529

531    
532            Give the tables titles so that the GUI can display more meaningful

602            remove tables
603    
604            * test/test_session.py (TestSessionSimple.test_remove_table): New.
605            Test for RemoveTable
606    
607    2003-05-22  Thomas Koester  <[email protected]>
608    
609            * Thuban/Model/classgen.py: Added short module doc string and CVS id.

711    
712            * Thuban/Model/classgen.py (ClassGenerator.GenQuantiles): Remove
713            references to 'inf' and use new Range __init__ to pass floats
714            directly rather than converting them to strings first.
715            Fixes RTBug #1876.
716    
717            * Thuban/Model/classification.py (ClassGroupRange.SetRange):
718            Use new Range ___init__ to pass floats.
719    
720            * Thuban/Model/layer.py (RasterLayer.__init__): Test if the
721            filename is a valid image file. Throw IOError otherwise.

730    
731            * Thuban/UI/projdialog.py (GeoPanel.__init__): Put Degrees as

745            Fixes RTBug #1880.
746    
747            * Thuban/UI/view.py: Added checks against if scale == 0. This
748            is a serious problem that can occur when an image without
749            geo data is loading and causes the map projection bounds to
750            go to infinity. Right now, the solution is to simply try
751            to recover.
752    
753            * extensions/thuban/cpl_mfile.cpp (MFILEClose): Make sure

760    
761            * test/test_range.py: Copied over tests from SciParam. Removed
762            tests against importing. Fixes RTBug #1867.

766            * test/test_load.py: Remove unused imports and restructure the
767            test code
768            (LoadSessionTest): Split into one class for each test and turn
769            LoadSessionTest itself into the base class for all such session
770            tests.
771            (ClassificationTest): New base class for load tests that test
772            classifications
773            (TestSingleLayer, TestLayerVisibility, TestClassification)
774            (TestLabels, TestLayerProjection, TestRasterLayer): New classes
775            for the individual tests
776

784            Added 'Gauss Krueger Zone 6'.
785    
786            * Data/iceland_sample_raster.thuban: political polygon now
787            filled transparent to have the raster image visible at once.
788    
789    2003-05-21  Frank Koormann  <[email protected]>
790    
791            * Thuban/UI/mainwindow.py (MainWindow): Renamed _OnClose() back to
792            OnClose() to keep in sync with extensions. Internally Thuban
793            still uses "underscored" names.

797            This puts back Raster layer support. These layers support projections
798            through the GDAL library. Currently, the CVS version is being used.
799            There are no Debian packages available although this may change soon.
800            A GDAL driver was extended to support writing to memory rather to
801            files.
802    
803            There is still some work that needs to be done, such as some error
804            handling when loading invalid images or when there is a problem
805            projecting the image. This putback simply checks in the majority
806            of the work.
807    
808            * setup.py: Add gdalwarp library extension.
809    
810            * Thuban/Model/layer.py (BaseLayer.HasClassification): New.
811            Defaults to False, but can be overridden by subclasses if they
812            support classification.
813            (RasterLayer): New. Defines a new layer that represents an
814            image.
815    
816            * Thuban/Model/load.py (SessionLoader.__init__): Add rasterlayer
817            tag handler.
818            (SessionLoader.start_layer): Encode the filename.

822            * Thuban/Model/map.py (Map.BoundingBox): Fix typo in comment.
823    
824            * Thuban/Model/save.py (XMLWriter.encode): Don't assume that we
825            get a string in Latin1. If we get such as string convert it to
826            unicode first, otherwise leave if alone before encoding.
827            (SessionSaver.write_layer): Add support for writing both Layers
828            and RasterLayers.
829    
830            * Thuban/Model/transientdb.py (AutoTransientTable.SimpleQuery):
831            The right argument may not be a string, it could also be a Column.
832    
833            * Thuban/UI/application.py (ThubanApplication.CreateMainWindow):
834            Make initial window size 600x400. Fixes RTBug #1872.
835    
836            * Thuban/UI/classifier.py (Classifier.__init__): Rearrange how
837            the dialog is constructed so that we can support layers that
838            do not have classifications.
839            (Classifier._OnTry): Only build a classification if the layer
840            supports one.
841    
842            * Thuban/UI/legend.py: Change all checks that a layer is an
843            instance of Layer into checks against BaseLayer.
844            (LegendTree.__FillTreeLayer): Only add children to a branch if
845            the layer supports classification.
846    
847            * Thuban/UI/mainwindow.py (MainWindow.NewSession,
848            MainWindow.OpenSession): Don't proceed with an action if the
849            user chooses Cancel when they are asked to save changes.
850            (MainWindow.AddRasterLayer): New. Open a dialog to allow the
851            user to select an image file. Create a new RasterLayer and add
852            it to the map.
853

863    
864            * Thuban/UI/view.py (MapCanvas.set_view_transform): Try to limit
865            how small the scale can get. This still needs more testing.
866    
867            * extensions/thuban/bmpdataset.cpp: New, but copied from GDAL.
868            Provides a driver to output in .bmp format.
869    
870            * extensions/thuban/cpl_mfile.cpp, extensions/thuban/cpl_mfile.h:
871            New. Provides IO routines which write to memory, rather than a file.
872    
873            * extensions/thuban/gdalwarp.cpp: New, but basically a direct copy
874            of the gdalwarp utility provided in GDAL. Added function calls
875            that can be accessed from python.
876    
877            * Data/iceland_sample_raster.thuban: New. Sample file that uses
878            a raster layer.

910    
911            * Thuban/Model/save.py: Remove some unused imports including the
912            __future__ import for nested_scopes as Thuban relies on Python 2.2
913            now.
914            (XMLWriter.encode): Remove the special case for a None argument.
915            In the saver encode is always called with a string argument.

919            * Thuban/UI/__init__.py: Remove the work-around for the locale bug
920            in wxPython (at least when usinvg wxGTK) prior to 2.4. The symptom
921            of the bug was that e.g. float("1.2") would fail. Thuban now
922            requires 2.4.x.

1085            * Thuban/UI/tableview.py (TableGrid.OnRangeSelect): Fix some issues
1086            with correctly selecting the rows and issuing the right events.
1087            Be sure to call Skip() to allow the grid to do some of its own
1088            handling which allows the rows to actually be selected.
1089            (LayerTableGrid.select_shapes): Rename from select_shape. Supports
1090            selecting multiple shapes.

1200            * Resources/Bitmaps/fulllayerextent.xpm,
1201            Resources/Bitmaps/fullselextent.xpm: Replaced the place holders with
1202            new icons.
1203    
1204    2003-05-06  Bernhard Herzog  <[email protected]>
1205    
1206            * Thuban/Model/transientdb.py (AutoTransientTable.SimpleQuery):
1207            New. Simply delegate to the transient table's version.

1214    
1215            * Thuban/Model/transientdb.py (TransientTableBase.SimpleQuery):
1216            Implement a simple query method for the query dialog
1217            (TransientTableBase.create): Add an INTEGER PRIMARY KEY that holds
1218            the row index or shapeid.

1228    
1229    2003-05-06  Bernhard Herzog  <[email protected]>
1230    
1231            Convert all table users to use the new table interface. This only
1232            covers Thuban itself, not GREAT-ER or other applications built on
1233            Thuban yet, so the compatibility interface stays in place for the
1234            time being but it now issues DeprecationWarnings.
1235    
1236            Finally, the new Table interface has a new method, HasColumn.
1237    
1238            * Thuban/Model/table.py (OldTableInterfaceMixin): All methods
1239            issue deprecation warnings when they're. The warnings refer to the
1240            caller of the method.
1241            (OldTableInterfaceMixin.__deprecation_warning): New. Helper method
1242            for the deprecation warnings
1243    
1244            * test/test_table.py: Ignore the deprecation warnings for the old
1245            table in the tests in this module. The purpose of the tests is to
1246            test the old interface, after all.
1247    
1248            * test/test_transientdb.py
1249            (TestTransientTable.run_iceland_political_tests): Use the

1272            * Thuban/Model/transientdb.py (TransientTableBase.HasColumn)
1273            (AutoTransientTable.HasColumn): Implement the new table interface
1274            method
1275            (AutoTransientTable.ReadRowAsDict, AutoTransientTable.ValueRange)
1276            (AutoTransientTable.UniqueValues): Adapt to new table interface

1296            Addresses the "Selection Extent" wish of RTbug #1787.
1297    
1298            * Resources/Bitmaps/fulllayerextent.xpm,
1299            Resources/Bitmaps/fullselextent.xpm: Bitmaps for layer and selection
1300            extent. These are just place holders for the real bitmaps.
1301    
1302            * Thuban/Model/layer.py (Shape): Since a Shape is immutable only
1303            calculate the bounding box once (the first time compute_bbox() is
1304            called).
1305            (Layer.ShapesBoundingBox): New. Given a list of shape ids, return
1306            the bounding box for the shapes in lat/long coordinates.
1307    
1308            * Thuban/UI/mainwindow.py: Added new "Full selection extent" menu
1309            option.

1311            any selected shapes.
1312            (MainWindow.FullSelectionExtent): New. Calls
1313            MapCanvas.FitSelectedToWindow() when the user selects the menu option.
1314            (_has_selected_shapes): New. Returns true if there are any
1315            selected shapes.

1318            true if there are any selected shapes.
1319    
1320            * Thuban/UI/view.py (MapCanvas): Added delegated method
1321            HasSelectedShapes.

1336            * Resources/Projections/defaults.proj: Added UK National Grid.
1337    
1338            * Thuban/UI/mainwindow.py: Added new "Full layer extent" menu option.

1345    2003-05-05  Bernhard Herzog  <[email protected]>
1346    
1347            Convert the table implementations to a new table interface. All
1348            tables use a common mixin class to provide backwards compatibility
1349            until all table users have been updated.
1350    
1351            * Thuban/Model/table.py (OldTableInterfaceMixin): Mixin class to
1352            provide backwards compatibility for table classes implementing the
1353            new interface
1354            (DBFTable, MemoryTable): Implement the new table interface. Use
1355            OldTableInterfaceMixin as base for compatibility
1356            (DBFColumn, MemoryColumn): New. Column description for DBFTable
1357            and MemoryTable resp.
1358    
1359            * test/test_dbf_table.py: New. Test cases for the DBFTable with
1360            the new table interface.
1361    
1362            * test/test_memory_table.py: New. Test cases for the MemoryTable
1363            with the new table interface.
1364    
1365            * test/test_table.py: Document the all tests in this file as only
1366            for backwards compatibility. The equivalent tests for the new
1367            interface are in test_memory_table.py and test_dbf_table.py
1368            (MemoryTableTest.test_read): field_info should be returning tuples
1369            with four items
1370            (MemoryTableTest.test_write): Make doc-string a more precise.
1371    
1372            * Thuban/Model/transientdb.py (TransientTableBase): Convert to new
1373            table interface. Derive from from OldTableInterfaceMixin for
1374            compatibility.
1375            (TransientTableBase.create): New intance variable column_map to
1376            map from names and indices to column objects
1377            (TransientTable.create): Use the new table interface of the input
1378            table
1379            (AutoTransientTable): Convert to new table interface. Derive from
1380            from OldTableInterfaceMixin for compatibility.
1381            (AutoTransientTable.write_record): Removed. It's not implemented
1382            yet and we still have to decide how to handle writing with the new
1383            table and data framework.
1384    
1385            * test/test_transientdb.py
1386            (TestTransientTable.run_iceland_political_tests)
1387            (TestTransientTable.test_transient_joined_table): Use the new

1391    
1392            This is namely a collection of UI updates to improve user interactivity.
1393            Tabbing between controls now exists and you can use ESC to close dialog
1394            boxes; ENTER will active the default button.
1395    
1396            * Thuban/UI/classgen.py (ClassGenDialog.__init__): Rearrange the
1397            order that the controls are created so that tabbing works correctly.
1398            (ClassGenDialog.OnOK): Renamed from _OnGenerate() so that the
1399            wxDialog can handle the default button correctly.
1400            (ClassGenDialog.OnCancel): Renamed from _OnCloseBtn() for the
1401            same reasons as for OnOK.
1402            (GenUniformPanel._OnRetrieve): Call wxBeginBusyCursor/wxEndBusyCursor
1403            when we ask the table for the maximum/minimum values of a field
1404            which could take a very long time.
1405    
1406            * Thuban/UI/classifier.py (Classifier.__init__): Rearrange the
1407            order that the controls are created so that tabbing works correctly.
1408            (SelectPropertiesDialog.__init__): Rearrange the order that the
1409            controls are created so that tabbing works correctly.
1410    
1411            * Thuban/UI/dialogs.py: Copied NonModalDialog box and changed it
1412            to derive from a wxDialog but behave like the original implementation
1413            which was derived from a wxFrame. wxDialog provides useful key
1414            handling functionality like ESC calling OnCancel and ENTER calling
1415            OnOK which is lost with wxFrame.
1416    
1417            * Thuban/UI/mainwindow.py: Add "..." to menu items that will open
1418            new dialogs.
1419    
1420            * Thuban/UI/projdialog.py (ProjFrame.__init__): Rearrange the
1421            order that the controls are created so that tabbing works correctly.
1422            (ProjFrame.OnApply): Renamed from _OnTry() to use wxDialog behaviour.
1423            (ProjFrame.OnOK): Renamed from _OnOK() to use wxDialog behaviour.
1424            (ProjFrame.OnCancel): Renamed from _OnClose() to use wxDialog behaviour.
1425            (ProjPanel.__init__): Add "Airy" to the list of ellipsoids so we
1426            can provide the "UK National Grid" as a default projection.
1427            (UTMPanel.__init__): Rearrange the order that the controls are
1428            created so that tabbing works correctly.
1429    
1430    2003-05-05  Bernhard Herzog  <[email protected]>
1431    
1432            * extensions/thuban/wxproj.cpp: Fix some of the comments.
1433            (project_point): If a map projection but no layer projection is
1434            given, convert degrees to radians before applying the map
1435            projection.
1436    
1437            * Thuban/UI/tableview.py (TableGrid.disallow_messages)
1438            (TableGrid.allow_messages): New methods to make it possible to
1439            inhibit message sending.
1440            (TableGrid.issue): Only send the message if not inhibited.
1441            (LayerTableGrid.select_shape): Use the new methods to make sure
1442            that no ROW_SELECTED message is sent while we're updating the
1443            selected rows to match the selected shapes.
1444

1446    
1447            Implementation of MemoryTable.
1448    
1449            * Thuban/Model/table.py (MemoryTable): New. Quite simple table
1450            implementation that operates on a list of tuples. All of the data
1451            are kept in the memory.
1452    
1453            * test/test_table.py (MemoryTableTest): New.
1454    
1455            * test/test_transientdb.py (SimpleTable): Removed.
1456            (TestTransientTable.test_transient_joined_table,
1457            (TestTransientTable.test_transient_table_read_twice): Replaced
1458            SimpleTable by MemoryTable.
1459    
1460    2003-04-30  Jonathan Coles   <[email protected]>
1461    
1462            * Data/iceland_sample.thuban: Now contains correct projections
1463            for each of the layers.
1464    
1465            * Resources/Projections/defaults.proj: Geographic projection
1466            contains unit conversion parameter.
1467    
1468    2003-04-30  Jonathan Coles   <[email protected]>
1469    
1470            The most important part of this putback is the projection changes.
1471            It should now be possible to specify the projection that a layer
1472            is in and then specify a different projection for the map. The
1473            projection dialog has an extra parameter for a geographic projection
1474            which lets the user select if the input is in degrees or radians.
1475    
1476            * Thuban/Model/layer.py (Layer.ShapesInRegion): Fix docstring
1477            to say that the parameter is a tuple of unprojected
1478            points (which is what the callers to this method were assuming).
1479            Also, since the points are unprojected we need to projected them.
1480    
1481            * Thuban/UI/legend.py (LegendTree.MoveCurrentItemUp,
1482            LegendTree.MoveCurrentItemDown): If the layer or any of the layer's
1483            groups are selected, move the layer up/down. Fixes RTbug #1833.
1484    
1485            * Thuban/UI/mainwindow.py: Move menu item map_rename up.
1486    
1487            * Thuban/UI/projdialog.py (ProjFrame._OnSave): Add missing
1488            parameter in call to SetClientData.
1489            (GeoPanel): Add support for selecting the units that the
1490            source data is in (Radians or Degrees).
1491    
1492            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Optimize
1493            the rendering loop by reducing the number of if's, removing the
1494            unnecessary try/except block, and checking if the old group
1495            is the same as the new one (which happens a lot if there is
1496            no classification, or lots of shapes are in the same group).
1497    
1498            * Thuban/UI/view.py (MapCanvas.OnPaint): Add a try/except block
1499            around the redraw routine to try to catch problems that the user
1500            may create by selecting invalid projections for the data set and
1501            map. Clears the display if there are any problems and prints the
1502            error.
1503            (MapCanvas.do_redraw): Use DC.Clear() instead of drawing a filled
1504            rectangle.
1505    
1506            * extensions/thuban/wxproj.cpp (project_point): First invert the
1507            supplied point (which should be in projected coordinates) using
1508            the layer's projection and then project the point using the
1509            map's projection.
1510            (project_points): Use project_point() to project each point.
1511    
1512    2003-04-30  Jan-Oliver Wagner <[email protected]>
1513    
1514            * Thuban/Model/layer.py (Layer.SetShapeStore): Fixed a bug:
1515            don't set the Classification to None if the classfication field
1516            is None (ie only a DEFAULT).
1517    
1518    2003-04-30  Bernhard Herzog  <[email protected]>
1519    
1520            * Thuban/UI/view.py: Fix some typos.
1521    
1522            * Thuban/UI/mainwindow.py (MainWindow.identify_view_on_demand): Do
1523            not pop up the dialog if the selection becomes empty (this could
1524            happen if e.g. a new selection is opened while the identify tool
1525            is active and dialog had been closed)
1526    
1527    2003-04-30  Bernhard Herzog  <[email protected]>
1528    
1529            * Thuban/Model/transientdb.py (TransientTableBase.__init__): New
1530            instance variable read_record_last_result
1531            (TransientTableBase.read_record): Make sure reading the same
1532            record twice works. The implementation uses the new instance
1533            variable read_record_last_result
1534    
1535            * test/test_transientdb.py
1536            (TestTransientTable.test_transient_table_read_twice): New test
1537            case for the above bug-fix.
1538    
1539    2003-04-29  Jonathan Coles   <[email protected]>
1540    
1541            * Thuban/common.py: Removed. No longer needed Str2Num. RTbug #1832.
1542    
1543            * Thuban/UI/classgen.py: Remove all uses of Str2Num.
1544    
1545            * Thuban/UI/classifier.py: Remove all uses of Str2Num.
1546            (ClassTable.SetValueAsCustom): Rename keyword argument in
1547            ClassGroup* constructors to match argument name.
1548    
1549    2003-04-29  Bernhard Herzog  <[email protected]>
1550    
1551            * Thuban/Model/session.py (Session.Destroy): Explicitly close the
1552            transient DB if it exists to make sure it doesn't leave a journal
1553            file in the temp directory.
1554    
1555            * Thuban/Model/transientdb.py (TransientDatabase.close): Set
1556            self.conn to None after closing the connection to make sure it's
1557            not closed twice
1558    
1559    2003-04-29  Jonathan Coles   <[email protected]>
1560    
1561            Add a visible parameter in the layer XML tag. The default value is
1562            "true". If anything other than "false" is specified we also assume
1563            "true". Addresses RTbug #1025.

1593            Next step of table implementation. Introduce a transient database
1594            using SQLite that some of the data is copied to on demand. This
1595            allows us to do joins and other operations that require an index
1596            for good performance with reasonable efficiency. Thuban now needs
1597            SQLite 2.8.0 and pysqlite 0.4.1. Older versions may work but I
1598            haven't tested that.
1599            
1600            * Thuban/Model/transientdb.py: New. Transient database
1601            implementation.
1602    
1603            * test/test_transientdb.py: New. Tests for the transient DB
1604            classes.
1605    
1606            * Thuban/Model/session.py (AutoRemoveFile, AutoRemoveDir): New
1607            classes to help automatically remove temporary files and
1608            directories.
1609            (Session.__init__): New instance variables temp_dir for the
1610            temporary directory and transient_db for the SQLite database
1611            (Session.temp_directory): New. Create a temporary directory if not
1612            yet done and return its name. Use AutoRemoveDir to have it
1613            automatically deleted
1614            (Session.TransientDB): Instantiate the transient database if not
1615            done yet and return it.
1616    
1617            * Thuban/Model/data.py (ShapefileStore.__init__): Use an
1618            AutoTransientTable so that data is copied to the transient DB on
1619            demand.
1620            (SimpleStore): New class that simply combines a table and a
1621            shapefile
1622    
1623            * Thuban/Model/table.py (Table, DBFTable): Rename Table into
1624            DBFTable and update its doc-string to reflect the fact that this
1625            is only the table interface to a DBF file. Table is now an alias
1626            for DBFTable for temporary backwards compatibility.
1627    
1628            * Thuban/UI/application.py (ThubanApplication.OnExit): Make sure
1629            the last reference to the session goes away so that the temporary
1630            files are removed properly.
1631    
1632            * test/test_load.py (LoadSessionTest.tearDown): Remove the
1633            reference to the session to make sure the temporary files are
1634            removed.
