1    2003-06-20  Jonathan Coles   <[email protected]>
2    
3            * Thuban/Model/layer.py (BaseLayer.HasShapes): New. Overridden
4            by deriving classes to determine if that layer supports shapes.
5            (Layer): Override HasShapes and return true.
6    
7            * Thuban/UI/classgen.py: Use Thuban[Begin|End]BusyCursor()
8            instead of a direct call to wx[Begin|End]CusyCursor().
9            (GenUniquePanel._OnRetrieve): Set busy cursor while retrieving
10            table data.
11    
12            * Thuban/UI/common.py (ThubanBeginBusyCursor, ThubanEndBusyCursor):
13            New. Wrappers around the wxWindows functions that allow us to
14            make additional calls such as wxYield which gives the native
15            system a chance to update the cursor correctly.
16    
17            * Thuban/UI/tableview.py: Use Thuban[Begin|End]BusyCursor()
18            instead of a direct call to wx[Begin|End]CusyCursor().
19    
20            * Thuban/UI/view.py: Use Thuban[Begin|End]BusyCursor()
21            instead of a direct call to wx[Begin|End]CusyCursor().
22            (MapCanvas.find_shape_at): Check if the current search layer
23            support shapes, otherwise go on to the next layer.
24    
25            * test/test_layer.py: Add tests in each type of layer for
26            HasClassification() and HasShapes()
27    
28    2003-06-20  Jonathan Coles   <[email protected]>
29    
30            * Thuban/UI/view.py (MapCanvas.OnPaint): Call wxYield after
31            turning on the busy cursor to allow the system to change the
32            cursor before we begin painting. This fixes a problem that
33            was occuring only under GTK. Fixes RTbug #1840.
34    
35    2003-06-20  Bernhard Herzog  <[email protected]>
36    
37            * Resources/XML/thuban-0.8.dtd: New DTD for the new file format
38            version.
39    
40            * Thuban/Model/save.py (sort_data_stores): New. Make topological
41            sort of the data sources so they can be written with sources that
42            data sources that depend on other data sources come after the
43            sources they depend on.
44            (SessionSaver.__init__): Add idmap instance variable to map from

49            (SessionSaver.write_session): Add a namespace on the session and
50            write out the data sources before the maps.
51            (SessionSaver.write_data_containers): New. Write the data
52            containers.
53            (SessionSaver.write_layer): Layer elements now refer to a
54            shapestore and don't contain filenames anymore.

56            * Thuban/Model/load.py (LoadError): Exception class to raise when
57            errors in the files are discovered
58            (SessionLoader.__init__): Define dispatchers for elements with a
59            thuban-0.8 namespace too.
60            (SessionLoader.check_attrs): New helper method to check and
61            convert attributes

68            addition to filename.
69            (SessionLoader.start_table, SessionLoader.end_table): Removed.
70            They were never used in the old formats and aren't needed for the
71            new.
72    
73            * Thuban/Model/session.py (Session.DataContainers): New method to
74            return all "data containers", i.e. shapestores and tables
75    
76            * test/xmlsupport.py (SaxEventLister.__init__)
77            (SaxEventLister.startElementNS, sax_eventlist): Add support to
78            normalize IDs.

103            (SaveSessionTest.testClassifiedLayer): Adapt to new file format.
104            (SaveSessionTest.testLayerProjection): The filename used was the
105            same as for testSingleLayer. Use a different one.
106            (SaveSessionTest.test_dbf_table)
107            (SaveSessionTest.test_joined_table): New test cases for saving the
108            new data sources structures.
109            (TestStoreSort, MockDataStore): Classes to test the sorting of the

116            * test/test_session.py
117            (UnreferencedTablesTests.test_unreferenced_tables_with_joins):
118            Use the cultural_landmark-point.dbf file for the store so that
119            the table rows and shape count match.
120    
121    2003-06-20  Jonathan Coles   <[email protected]>
122    
123            * Thuban/Model/data.py (DerivedShapeStore.__init__): Raise
124            an exception if the number of shapes is different from the
125            number of rows in the table. Address RTbug #1933.
126    
127            * test/test_layer.py (TestLayer.test_derived_store): Add
128            a test for the new exception in DerivedShapeStore.__init__.
129    
130            * test/support.py (FloatTestCase): Removed since there is
131            already FloatComparisonMixin. Fixes RTbug #1954.
132            (FloatComparisonMixin.assertFloatEqual): Include test for
133            infinity that was part of FloatTestCase.
134    
135            * test/test_range.py (RangeTest): Inherit from
136            support.FloatComparisonMixin now that we don't have
137            support.FloatTestCase.
138    
139    2003-06-20  Bernhard Herzog  <[email protected]>
140    
141            * test/test_save.py (SaxEventLister, sax_eventlist): Removed. Use
142            the implementation in xmlsupport instead.

144    
145            * test/test_proj.py: Import sax_eventlist from xmlsupport instead
146            of test_save
147    
148    2003-06-20  Bernhard Herzog  <[email protected]>
149    
150            * test/test_load.py (LoadSessionTest.check_format): New helper
151            method to make sure the test files we load might have been written
152            by the current thuban version.
153            (ClassificationTest.TestLayers, TestSingleLayer.test)
154            (TestLayerVisibility.test, TestClassification.test)
155            (TestLabels.test, TestLayerProjection.test, TestRasterLayer.test):
156            Add check_format() calls and fix the thuban data to match the data
157            that would be written by saving the session loaded from it.
158    
159            * test/xmlsupport.py (SaxEventLister, sax_eventlist): Copies of
160            the same class and function in test_save.
161    
162            * test/test_xmlsupport.py (TestEventList): New. test cases for
163            sax_eventlist
164    
165    2003-06-20  Bernhard Herzog  <[email protected]>
166    
167            * Resources/XML/thuban.dtd: Add comment about which versions of
168            Thuban are covered by this DTD
169            (map): Fix content model for layers and raster layers. There can
170            be any number or layers and raster layers in any order.
171    
172    2003-06-20  Jonathan Coles   <[email protected]>
173    
174            This is mainly about fixing RTbug #1949.
175    
176            * Thuban/Model/classification.py: Remove "from __future__"
177            import statement since python 2.2 is the earliest supported
178            version.
179    
180            * Thuban/Model/proj.py (Projection.GetProjectedUnits): New.
181            Currently returns PROJ_UNITS_METERS or PROJ_UNITS_DEGREES
182            depending on the units this projection *forwards* into.
183    
184            * Thuban/Model/save.py (SessionSaver.write_classification):
185            Remove unnecessary use of lambdas and nested functions.
186    
187            * Thuban/UI/legend.py (ScaleBarBitmap.__SetScale): Do scale
188            adjustment here if the map projection uses degrees.
189    
190            * Thuban/UI/scalebar.py (ScaleBar.DrawScaleBar): Remove
191            scale adjust code since it is now done before calling
192            this method. Don't do anything if the map projection
193            is None.
194    
195    2003-06-19  Bernhard Herzog  <[email protected]>
196    
197            Move version specific load tests to their own file.
198    
199            * test/test_load.py: Expand the doc-string to explain a bit how to
200            handle file format changes.
201            (TestClassification.test): Update the docstring as this test is
202            not about Thuban 0.2 anymore.
203    
204            * test/test_load_0_2.py: New file with the load tests for thuban
205            files created with Thuban 0.2 and earlier.
206    
207    2003-06-19  Bernhard Herzog  <[email protected]>
208    
209            Add XML validation to some of the tests. Validation will only be
210            done if pyRXP is installed (http://reportlab.com/xml/pyrxp.html).
211            To make the DTD available to the test cases it's moved into
212            Resources/XML
213    
214            * Resources/XML/thuban.dtd: New. This is now the real Thuban DTD
215            for versions up to and including 0.2. Two slight changes: added an
216            encoding specification and fixed the comment which refered to
217            GRASS, not Thuban
218    
219            * test/xmlsupport.py: New support module for tests involving XML.
220            Currently there's a mix-in class for XML validation.
221    
222            * test/test_xmlsupport.py: New. Tests for the xmlsupport module
223    
224            * test/test_save.py (SaveSessionTest): Derive from ValidationTest
225            so that we can validate the
226            (SaveSessionTest.testEmptySession)
227            (SaveSessionTest.testSingleLayer)
228            (SaveSessionTest.testSingleLayer)
229            (SaveSessionTest.testLayerProjection)
230            (SaveSessionTest.testRasterLayer)
231            (SaveSessionTest.testClassifiedLayer): Validate the generated XML
232    
233            * test/runtests.py (main): Call print_additional_summary instead
234            of print_garbage_information
235    
236            * test/support.py (resource_dir): New function to return the
237            "Resource" subdirectory
238            (print_additional_summary): New function to combine several
239            summary functions
240            (run_tests): Use print_additional_summary instead of calling
241            print_garbage_information directly
242    
243    2003-06-19  Bernhard Herzog  <[email protected]>
244    
245            * Doc/thuban.dtd (classification): Correct the content model of
246            the classification element.
247            (projection): Add the "name" attribute
248    
249    2003-06-19  Frank Koormann   <[email protected]>
250    
251            MERGE from the greater-ms3 branch.
252    
253            * Thuban/UI/scalebar.py (ScaleBar.DrawScaleBar): Apply conversion to
254            scale if projection is latlong to get better estimate.
255    
256            Fix problem of hidden properties dialog under windows after double
257            click on layer tree:
258            The tree control always gets an Expanded / Collapsed event after
259            the ItemActivated  on double click, which raises the main window again.         We add a second ItemActivated event to the queue, which simply
260            raises the already displayed window.
261    
262            * Thuban/UI/legend.py (LegendTree.__init__): Instance variable
263            raiseProperties initialized to prevent endless loops
264            (LegendTree._OnItemActivated): Depending on self.raiseProperties
265            simply raise the properties or open the dialog and issue a second
266            event.
267    
268    2003-06-18  Jonathan Coles   <[email protected]>
269    
270            * setup.py: Fix a few problems that occured under Windows.
271    
272    2003-06-18  Jonathan Coles   <[email protected]>
273    
274            When Thuban loaded the map was redrawn twice because the
275            legend was being opened after the mainwindow was created
276            and not during its creation. This meant the map was drawn
277            initially and then had to be redrawn when the legend
278            caused the display to change. Now the legend is opened
279            in the mainwindow constructor which resolves this issue.
280    
281            Also, although we were checking for the existence of
282            gdal and gdalwarp modules, the gdalwarp extension was
283            still being compiled (which may fail if the system doesn't
284            have gdal installed). the build_ext command to setup.py
285            now accepts the flags --with-gdal and --without-gdal.
286            If --without-gdal is specified setup.py will try to
287            use the gdal parameters specified by gdal-config. Under
288            windows, those parameters have to be set in setup.py
289            as with proj4 an wxWindows.
290    
291            * setup.py: Use a list instead of seperate variables for
292            extension parameters so we can create a generic function
293            that runs an appropriate *-config script.
294            (run_cs_script): Renamed from run_wx_script and modified
295            to accept a second argument which is a list of lists to
296            be filled in by the values returned from running the command.
297            (thuban_build_ext): New. Extends the build_ext command and
298            provides the options --with-gdal/--without-gdal which then
299            optionally includes the gdalwarp extension.
300    
301            * Thuban/Model/resource.py: First check if we can import
302            the gdalwarp Thuban extension before checking for gdal.
303            Also added some comments.
304            
305            * Thuban/UI/legend.py (ScaleBarBitmap.__SetScale): Check if
306            the map is None which may be the case if none has been loaded
307            yet.
308    
309            * Thuban/UI/main.py (main): Remove call to ShowLegend.
310    
311            * Thuban/UI/mainwindow.py (MainWindow.__init__): Call ShowLegend().
312    
313            * Thuban/UI/renderer.py: Check for gdal support before importing
314            gdalwarp.
315            (MapRenderer.render_map): Only try to optimize if we have gdal
316            support otherwise nothing will get drawn.
317    
318            * Thuban/UI/view.py (MapCanvas.FitMapToWindow): This may be called
319            during startup before a map has been created. Check if map is None
320            before using it and do nothing if it is.
321    
322    2003-06-17  Jonathan Coles   <[email protected]>
323    
324            Fix the problem with raster layers under Windows that caused
325            Thuban to crash. The view should respond to layer projection
326            changed events to update the display. Changes to a projection
327            should not cause the map to be set to full extent.
328            
329            * Thuban/UI/view.py (MapCanvas.__init__): New instance variable
330            current_map_proj to remember the current map projection so that
331            when the projection changes we know what the previous projection
332            was.
333            (MapCanvas.SetMap): Unsubscribe and subscribe to
334            LAYER_PROJECTION_CHANGED events.
335            (MapCanvas.projection_changed): Split into two methods that respond
336            to map and layer projection changes.
337            (MapCanvas.map_projection_changed): New. Takes the current view and
338            projects it using the new projection. This does not cause the
339            map to be redrawn at full extent.
340            (MapCanvas.layer_projection_changed): New. Cause a redraw which
341            will draw each layer in its new projection.
342            
343            * extensions/thuban/bmpdataset.cpp (BMPDataset::Open): Call
344            VSIFClose() not VSIFCloseL() to close the file. Fixes a crash
345            under Windows.
346            
347            * extensions/thuban/gdalwarp.cpp (MFILENAME): Padding should be
348            to twice sizeof(void*) because there are two digits for each
349            hex byte.
350    
351    2003-06-16  Bernhard Herzog  <[email protected]>
352    
353            Update to the layer interface: Direct access to the table,
354            shapetable, shapefile and filename attributes is now actively
355            deprecated by issuing deprecation warnings for all places where
356            this happens.
357    
358            * Thuban/Model/layer.py (Layer.__getattr__): New. Implement access
359            to the instance variables table, shapetable, shapefile and
360            filename via __getattr__ so that we can issue a deprecation
361            warning.
362            (Layer.SetShapeStore): Don't set the deprecated instance variables
363            any more
364            (Layer.SetShapeStore): Don't use deprecated layer instance
365            variables
366            (Layer.Destroy): No need to explicitly remove the instance
367            variables any more
368            (Layer.GetFieldType, Layer.Shape): Don't use deprecated layer
369            instance variables
370    
371            * Thuban/UI/classgen.py (ClassGenDialog.__init__)
372            (GenUniformPanel._OnRetrieve, GenUniquePanel._OnRetrieve)
373            (GenQuantilesPanel.GetList, GenQuantilesPanel.OnRetrieve): Don't
374            use deprecated layer instance variables
375    
376            * Thuban/UI/classifier.py (Classifier.__init__): Don't use
377            deprecated layer instance variables
378    
379            * Thuban/UI/identifyview.py (IdentifyListCtrl.selected_shape)
380            (IdentifyGridCtrl.selected_shape): Don't set the deprecated layer
381            instance variables
382    
383            * Thuban/UI/tableview.py (LayerTableGrid.select_shapes): Don't use
384            deprecated layer instance variables
385    
386            * Thuban/UI/mainwindow.py (MainWindow.LayerShowTable): Don't use
387            deprecated layer instance variables
388    
389            * Thuban/Model/save.py (SessionSaver.write_layer): Don't use
390            deprecated layer instance variables
391    
392            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer)
393            (MapRenderer.polygon_render_param): Don't use deprecated layer instance
394            variables
395    
396            * test/runtests.py (main): Turn Thuban's deprecation warnings into
397            errors so that they're cought by the tests
398    
399            * test/test_load.py (TestSingleLayer.test): Don't use deprecated
400            layer instance variables
401    
402    2003-06-16  Jonathan Coles   <[email protected]>
403    
404            Fix a problem under Windows whereby if the user double-clicks on a
405            layer in the legend that tree item will expand or collapse as well
406            as open the layer properties dialog. The state of the tree item
407            should not be affected.
408    
409            * Thuban/UI/legend.py (LegendTree.__init__): Add instance variable
410            preventExpandCollapse and subscribe to expanding and collapsing
411            events.
412            (LegendTree.OnItemExpandCollapse): New. Responds to expanding and
413            collapsing events and will veto the event if it has been triggered
414            by the user double clicking on a layer.
415            (LegendTree._OnItemActivated): Set preventExpandCollapse to indicate
416            that an expanding/collapsing event should be vetoed.
417    
418    2003-06-13  Bernhard Herzog  <[email protected]>
419    
420            * Thuban/UI/classifier.py (Classifier.OnClose)
421            (Classifier.map_layers_removed)
422            (Classifier.layer_shapestore_replaced): Unsubscribe the messages
423            in OnClose and not in map_layers_removed or
424            layer_shapestore_replaced to make sure it always happens when the
425            dialog is closed
426    
427    2003-06-13  Jonathan Coles   <[email protected]>
428    
429            This puts back a fix for Windows where a panel is needed so that
430            the background of the table view appears correctly.
431    
432            * Thuban/UI/tableview.py (TableFrame.__init__): Add a panel
433            object that can be used by derived classes to place any
434            controls (including the grid) onto.
435            (QueryTableFrame.__init__): Use the panel as the parent window
436            for all the controls. Reparent the grid so that the panel is
437            the parent. Call UpdateStatusText() to correctly initialize
438            the status bar.
439    
440    2003-06-13  Jonathan Coles   <[email protected]>
441    
442            * Thuban/UI/dialogs.py (ThubanFrame): New: a class that inherits
443            from wxFrame (as opposed to wxDialog like the other classes)
444            but otherwise behaves like the other classes. This is needed
445            for the TableView which isn't really a dialog and needs to
446            have a status bar and control buttons.
447    
448            * Thuban/UI/tableview.py (TableGrid.__init__): Create an
449            instance variable to keep track of how many rows are selected.
450            Subscribe once to the the events we are interested in.
451            (ThubanGrid.OnRangeSelect): Only handle event if event handling
452            hasn't been turned off.
453            (ThubanGrid.OnSelectCell): Only handle event if event handling
454            hasn't been turned off.
455            (ThubanGrid.ToggleEventListeners): Rather than subscribe None
456            as an event listener (which changes the event handler stack)
457            simply set an instance variable to False. This is checked in
458            the event handlers.
459            (ThubanGrid.GetNumberSelected): Return the number of currently
460            selected rows.
461            (TableFrame): Inherit from ThubanFrame so we can have a
462            status bar and control buttons.
463            (QueryTableFrame.__init__): Create a status bar. Fixes RTbug #1942.
464            Explicitly set which items are selected in the operator choice and
465            action choice so there is always a valid selection. Fixes RTbug #1941.
466            Subscribe to grid cell selection events so we can update the
467            status bar.
468            (QueryTableFrame.UpdateStatusText): Update the status bar with
469            how many rows are in the grid, how many columns, and how many
470            rows are selected.
471            (QueryTableFrame.OnGridSelectRange, QueryTableFrame.OnGridSelectCell):
472            Call UpdateStatusText when cells are (de)selected.
473            (QueryTableFrame.OnQuery): Use the string value in the value
474            combo if either the selected item index is 0 or if the string
475            cannot be found in the predefined list (this happens if the
476            user changes the text). Fixes RTbug #1940.
477            Only turn off the grid event listeners if there a query comes
478            back with a none empty list of ids. in the case that the list
479            is empty this causes a grid.ClearSelection() call to actually
480            clear the grid selection which causes the selected items in
481            the map to be deselected. Fixes RTbug #1939.
482    
483            * test/test_save.py (XMLWriterTest.Encode): Check return values.
484            Fixes RTbug #1851.
485    
486    2003-06-13  Bernhard Herzog  <[email protected]>
487    
488            * Thuban/UI/identifyview.py (IdentifyView.__init__): Call
489            self.selected_shape with the current selection to make sure the
490            contents of the dialog are up to date when it's shown for the
491            first time.
492            The dialog used to work without this by luck. The recent fix to
493            the connector module 'broke' a 'feature' the identify view was
494            relying on, i.e that subscribing to a message in response to
495            receiving a message of that type would mean that the new
496            subscriber would also be called for the same message.
497            
498    2003-06-12  Jonathan Coles   <[email protected]>
499    
500            * extensions/thuban/gdalwarp.cpp: Removed debug printing as
501            the image is rendered. Fixes RTbug #1937.
502    
503    2003-06-12  Jonathan Coles   <[email protected]>
504    
505            * Thuban/Lib/fileutil.py: As is done under Windows, create the
506            user directory if it doesn't exist on a posix system.
507            Fixes RTbug #1815.
508    
509            * Thuban/Model/resource.py (get_user_proj_files): Moved the
510            called to get_application_dir here, so that the directory
511            will only be called if this method is invoked.
512    
513            * Thuban/UI/projdialog.py (ProjFrame.__DoOnProjAvail): Clear
514            the projfilepath if no projection is selected.
515    
516    2003-06-12  Jonathan Coles   <[email protected]>
517    
518            * Thuban/UI/legend.py (ScaleBarBitmap.__SetScale): Don't draw
519            the scalebar if the current map has no projection set.
520    
521            * Thuban/UI/projdialog.py (ProjFrame.__DoOnProjAvail): Set the
522            projfilepath label to just the basename of the projection file
523            rather than include the entire path.
524    
525            * Thuban/Model/resource.py: Fix missed proj functions that
526            needed to be renamed.
527    
528    2003-06-12  Jonathan Coles   <[email protected]>
529    
530            * Thuban/Model/classification.py: Removed assert statements that
531            tested if the variable was an instance of Color.
532    
533            * Thuban/Model/color.py (Color): Remove commented code that isn't
534            used.
535            (Transparent): Renamed from NoColor. Doesn't inherit from Color.
536            Fixes RTbug #1835.
537            (Transparent.__eq__, Transparent.__ne, Transparent.__repr): New.
538            Needed now that the class doesn't inherit from Color.
539    
540    2003-06-12  Jonathan Coles   <[email protected]>
541    
542            * test/test_save.py (XMLWriterTest.testEncode): Explicitly
543            check unicode strings.
544    
545            * test/test_layer.py: Check for existence of gdal.
546    
547    2003-06-12  Jonathan Coles   <[email protected]>
548        
549            * Thuban/Model/xmlreader.py: New. Contains the XMLReader class
550            that was in load.py
551    
552            * Thuban/Model/xmlwriter.py: New. Contains the XMLWriter class
553            that was in save.py
554    
555    2003-06-12  Jonathan Coles   <[email protected]>
556    
557            This is largely a collection of bug fixes. We also handle the
558            case where gdal is not on the system. The XMLReader and XMLWriter
559            classes were moved into there own files to resolve some circular
560            import references and because they shouldn't really be in the
561            file that is dediciated to reading/writing session files since
562            they are also used elsewhere.
563    
564            * Thuban/Model/classgen.py: Renamed functions to follow the
565            function_names_with_underscores style. Fixes RTbug #1903.

572            * Thuban/Model/load.py (XMLReader): Moved into seperate file
573            xmlreader.py.

601            library is available. Addresses RTbug #1877.
602    
603            * Thuban/UI/application.py (ThubanApplication.OpenSession):
604            Display a message box if the gdal library is not available, but
605            only if there are any layers that would use it. Addresses RTbug #1877.
606    
607            * Thuban/UI/classgen.py: Use renamed projection resource functions.
608            (GenUniformPanel.__CalcStepping): Fix a slight discrepency
609            when using integers versus floats.
610    
611            * Thuban/UI/mainwindow.py (_has_gdal_support): New. Used to
612            determine if the "Add Image Layer" menu option should be
613            greyed out or not. Addresses RTbug #1877.
614    
615            * Thuban/UI/projdialog.py: Use renamed projection resource functions.
616    
617            * Thuban/UI/renderer.py (MapRenderer.render_map): Only try to

624            (test_calculate_quantiles): Fix some tests to catch the new
625            ValueError that is raised.
626    
627            * test/test_proj.py: Use renamed projection resource functions.
628    
629            * test/test_save.py (SaveSessionTest.testClassifiedLayer): New
630            test for saving classified layers. Fixes RTbug #1902.
631            (XMLWriterTest): New. Tests the XMLWriter class. Fixes RTbug #1851.
632    
633    2003-06-12  Jan-Oliver Wagner <[email protected]>
634    
635            Fix for http://intevation.de/rt/webrt?serial_num=1900.
636    
637            * Thuban/UI/multiplechoicedialog.py: New. A multiple choice dialog.
638    
639            * Thuban/UI/mainwindow.py: import wxMultipleChoiceDialog from
640            multiplechoicedialog.py rather than from the wxPython library.

648    
649            * Thuban/Lib/fileutil.py (get_application_dir): New function to
650            determine the absolute .thuban/thuban directory under
651            "posix" (os.expanduser) and "nt" (read AppData registry key).
652    
653            * Thuban/Model/resource.py: Use get_application_dir

662            (LayerTableFrame.OnClose): Unsubscribe from it.
663            (LayerTableFrame.map_layers_removed): New. Receiver for
664            MAP_LAYERS_REMOVED. Close the dialog when the layer whose the
665            dialog is showing is removed.
666

668    
669            * Thuban/Lib/connector.py (Connector.Issue): Iterate over a copy
670            of the receivers list so that unsubscribing in a receiver doesn't

674            (ConnectorTest.test_disconnect_in_receiver): New. Test whether
675            unsubscribing in a receiver works correctly. See docstring for
676            details
677

682    
683            * Thuban/Model/layer.py (Layer.SetShapeStore): Send

685            LAYER_CHANGED will still be sent if the classification changes.
686    
687            * Thuban/UI/classifier.py (Classifier.__init__): Add the map as
688            parameter so we can subscribe to some of its messages
689            (Classifier.__init__): Subscribe to the map's MAP_LAYERS_REMOVED
690            and the layer's LAYER_SHAPESTORE_REPLACED
691            (Classifier.unsubscribe_messages): New. Unsubscribe from message
692            subscribed to in __init__
693            (Classifier.map_layers_removed)
694            (Classifier.layer_shapestore_replaced): receivers for the messages
695            subscribed to in __init__. Unsubscribe and close the dialog
696    
697            * Thuban/UI/mainwindow.py (MainWindow.OpenLayerProperties): Pass
698            the map to the Classifier dialog
699    
700            * test/test_layer.py (SetShapeStoreTests): Derive from
701            SubscriberMixin as well so we can test messages
702            (SetShapeStoreTests.setUp): Subscribe to some of the layer's
703            messages
704            (SetShapeStoreTests.tearDown): Clear the messages again

721    
722            * Thuban/UI/identifyview.py (IdentifyView.__init__):
723            Layout reimplemented without panel. Make life easier to fit the list
724            in the dialog.
725    
726    2003-06-05  Frank Koormann  <[email protected]>
727    
728            * Thuban/UI/projdialog.py (ProjFrame.__init__): Fill the projchoice
729            once on initialisation (Former implementation resulted in multiple
730            entries for each projection).
731            (ProjFrame.__FillAvailList): selectProj as second optional parameter,
732            if set, select the projection found under the specified name. This
733            overwrites any other selection estimate.
734            Removed projchoice filling from this method.
735            (ProjFrame._OnSave, ProjFrame._OnAddToList):
736            Updated call of ProjFrame.__FillAvailList
737            (LCCPanel._DoLayout): Moved parameter controls in more common order.
738    
739            * Resources/Projections/defaults.proj: Extended defaults representing
740            various common European projections.
741    
742    2003-06-05  Frank Koormann  <[email protected]>
743    
744            * Thuban/UI/identifyview.py (IdentifyView.__init__):
745            Use ListCtrl instead of GridCtrl
746    
747            * Thuban/Model/resource.py:
748            Guess location of .thuban directory from tempdir parent directory.
749    
750            * Thuban/UI/application.py (ThubanApplication.read_startup_files):
751            Guess location of .thuban directory from tempdir parent directory.
752    
753    2003-06-04  Bernhard Herzog  <[email protected]>
754    
755            Do not cache the values returned by the tree widget's
756            GetFirstChild and GetNextChild methods because it led to lots of
757            segfaults. The new way requires more brute force but is more
758            reliable.
759    
760            * Thuban/UI/legend.py (LegendTree.__init__): Remove instance
761            variable layer2id
762            (LegendTree.find_layer): New method to do with brute force what
763            layer2id tried to accomplish
764            (LegendTree._OnMsgLayerChanged)
765            (LegendTree._OnMsgLayerTitleChanged, LegendTree.__ShowHideLayer):
766            Use find_layer instead of layer2id
767            (LegendTree.__RemoveLayer, LegendTree.__AddLayer): No need to
768            update layer2id anymore
769            (LegendTree._OnMsgMapLayersRemoved)
770            (LegendTree._OnMsgMapLayersAdded): Get by without layer2id.
771    
772    2003-06-03  Thomas Koester  <[email protected]>
773    
774            * Thuban/Model/classgen.py (GenQuantiles0): New function.
775    
776    2003-06-02  Bernhard Herzog  <[email protected]>
777

800    
801            * Thuban/UI/classgen.py (GenQuantilesPanel.GetList): Resource

804    2003-06-02  Bernhard Herzog  <[email protected]>
805    
806            * Thuban/UI/legend.py (LegendTree._OnMsgMapLayersRemoved): It's
807            possible that a layer is removed that is not currently selected in
808            the legend so don't check for this.
809    
810    2003-05-30  Bernhard Herzog  <[email protected]>
811    
812            * Thuban/Model/layer.py (Layer.Destroy): Set all instance
813            variables to None that have direct or indirect references to

872            (LegendTree.__RemoveLayer): Remove a layer from the legend.
873            (LegendTree.DeleteChildren): New, overrides wxTreeCtrl method.

890            to be compiled as a standalone app. Now the code can only be
891            called from Python which simplifies the parameter passing.
892            (ProjectRasterFile): Handle Python arguments. Remove code that
893            checks for a destination dataset. Add more clean up code.
894    
895            * test/test_map.py (TestMapWithContents.test_raise_layer_top,

1173    
1174            * Thuban/Model/transientdb.py (TransientTableBase.Width,
1175            TransientTableBase.Precision): Return column width and precision.
1176    
1177            * Thuban/UI/tableview.py (QueryTableFrame.OnSaveAs): Call table_to_dbf
1178            or table_to_csv depending on file selection.
1179    
1180            * test/test_dbf_table.py:
1181            Test table_to_dbf (extension of former part of test).
1182    
1183            * test/test_csv_table.py:
1184            Test table_to_csv.
1185    
1186    2003-05-23  Jan-Oliver Wagner <[email protected]>
1187    
1188            * Thuban/UI/join.py (JoinDialog.OnJoin): Use _() for strings.
1189            Use QueryTableFrame instead of TableFrame.
1190    
1191            * Thuban/UI/mainwindow.py (MainWindow.LayerShowTable): Prefix the
1192            table window with 'Layer Table:' instead of 'Table:'.
1193    
1194    2003-05-23  Jan-Oliver Wagner <[email protected]>
1195    
1196            Give all tables a title via mix-in TitledObject.LayerShowTable
1197    
1198            * Thuban/Model/base.py (TitledObject.SetTitle): Call method 'issue'
1199            only if it exists.
1200    
1201            * Thuban/Model/table.py (DBFTable, MemoryTable): mix-in TitledObject
1202            and call its init-method with a default title. Remove Title() method.
1203    
1204            * Thuban/Model/transientdb.py (TransientTable, TransientJoinedTable,
1205            AutoTransientTable): mix-in TitledObject and call its init-method with
1206            a default title. Remove Title() method.
1207    
1208    2003-05-23  Bernhard Herzog  <[email protected]>
1209    
1210            * Thuban/Model/session.py (Session.AddShapeStore): Define
1211            AddShapeStore analogously to AddTable.
1212    
1213            * test/test_session.py (TestSessionSimple.test_add_shapestore):
1214            New. Test for AddShapeStore
1215    
1216    2003-05-23  Jan-Oliver Wagner <[email protected]>
1217    
1218            Introducing QueryTableFrame and a very coarse ShowTable implementation.
1219    
1220            * Thuban/UI/tableview.py (LayerTableFrame, QueryTableFrame): Split the
1221            class LayerTableFrame into two classes, LayerTableFrame and QueryTableFrame.
1222            The latter implements the selection GUI without dependency on a layer.
1223            LayerTableFrame now is derived from QueryTableFrame and connects
1224            to a layer.
1225    
1226            * Thuban/UI/mainwindow.py (MainWindow.TableShow): A very coarse
1227            implementation that still needs work.
1228    
1229            * Thuban/Model/layer.py (Layer.TreeInfo): Added filename.
1230    
1231    2003-05-22  Frank Koormann  <[email protected]>
1232    
1233            * Thuban/Model/transientdb.py (TransientJoinedTable.__init__):
1234            Added "outer_join = False" as optional parameter.
1235            (TransientJoinedTable.create): If outer join is true, perform a
1236            "LEFT OUTER JOIN" instead of "JOIN", which preserves all records of
1237            the left table. Records not matching are filled with 0 / None.
1238    
1239            * Thuban/UI/join.py (JoinDialog.__init__): Checkbox for outer join.
1240            (JoinDialog.OnJoin): Consider outer join check box.
1241    
1242    2003-05-22  Bernhard Herzog  <[email protected]>
1243    
1244            * Thuban/UI/join.py (JoinDialog.OnJoin): Use exc_info in a
1245            somewhat safer way. Storing the traceback in a local variable can
1246            lead to memory leaks
1247    
1248    2003-05-22  Bernhard Herzog  <[email protected]>
1249    
1250            * Thuban/UI/join.py (JoinDialog.OnJoin): Make sure to really call

1252    
1253    2003-05-22  Frank Koormann  <[email protected]>
1254    
1255            * Thuban/UI/join.py (JoinDialog.__init__): Make use of
1256            TransientTable.Title()
1257    
1258    2003-05-22  Frank Koormann  <[email protected]>
1259    
1260            Join Dialog, initial version.
1261    
1262            * Thuban/UI/mainwindow.py (MainWindow.TableJoin): Removed print.
1263    
1264            * Thuban/UI/join.py (JoinDialog): Functional implementation of
1265            former framework. Renamed Table1/Table2 to LeftTable/RightTable
1266            in all occurences.
1267    
1268            * Thuban/Model/transientdb.py (TransientJoinedTable.__doc__):
1269            Typo fixed.
1270    
1271    2003-05-22  Bernhard Herzog  <[email protected]>
1272    
1273            Give the tables titles so that the GUI can display more meaningful
1274            names. For now the titles are fixed but depend on e.g. filenames
1275            or the titles of the joined tables.
1276    
1277            * Thuban/Model/transientdb.py (TransientTable.Title)
1278            (TransientJoinedTable.Title, AutoTransientTable.Title): New.
1279    
1280            * Thuban/Model/table.py (DBFTable.Title, MemoryTable.Title): New.
1281    
1282            * test/test_transientdb.py
1283            (TestTransientTable.test_auto_transient_table_title): New. Test
1284            for the Title method
1285            (TestTransientTable.test_transient_joined_table)
1286            (TestTransientTable.test_transient_table): Add test for the Title
1287            methods
1288    
1289            * test/test_memory_table.py (TestMemoryTable.test_title): New.
1290            Test for the Title method
1291    
1292            * test/test_dbf_table.py (TestDBFTable.test_title): New. Test for
1293            the Title method
1294    
1295    2003-05-22  Bernhard Herzog  <[email protected]>
1296    
1297            * test/test_layer.py (TestLayer.setUp, TestLayer.tearDown):
1298            Provide a better way to destroy the layers
1299            (TestLayer.test_base_layer, TestLayer.test_arc_layer)

1307            filename if the shape store actually has one.
1308    
1309    2003-05-22  Bernhard Herzog  <[email protected]>
1310    
1311            * Thuban/Model/table.py (DBFTable.FileName): New. Accessor method
1312            for the filename
1313    
1314            * test/test_dbf_table.py (TestDBFTable.test_filename): New. Test
1315            for the FileName method
1316            (TestDBFTableWriting.test_write): Fix spelling of filename
1317    
1318    2003-05-22  Thomas Koester  <[email protected]>
1319    
1320            * Thuban/Model/range.py, test/test_range.py: Brought over new Range
1321            from SciParam that now really is immutable.
1322    
1323    2003-05-22  Frank Koormann  <[email protected]>
1324    
1325            Layer Top/Bottom placement added to legend.

1331            New, methods binding the event methods with the map methods.
1332    
1333            * Thuban/Model/map.py (Map.TopLayer(), Map.BottomLayer()): New, place
1334            layer at top/bottom of layer stack.
1335    
1336            * Resources/Bitmaps/top_layer.xpm: New button icon.
1337    
1338            * Resources/Bitmaps/bottom_layer.xpm: New button icon.
1339    
1340    2003-05-22  Bernhard Herzog  <[email protected]>
1341    
1342            * Thuban/Model/session.py (Session.RemoveTable): New method to
1343            remove tables
1344    
1345            * test/test_session.py (TestSessionSimple.test_remove_table): New.
1346            Test for RemoveTable
1347    
1348    2003-05-22  Thomas Koester  <[email protected]>
1349    
1350            * Thuban/Model/classgen.py: Added short module doc string and CVS id.
1351            (ClassGenerator.GenUniformDistribution): Use new Range __init__, too.
1352    
1353    2003-05-22  Bernhard Herzog  <[email protected]>
1354    
1355            Implement a way to discover dependencies between tables and
1356            shapestores.
1357    
1358            * Thuban/Model/transientdb.py (TransientTableBase.Dependencies)
1359            (TransientJoinedTable.Dependencies)
1360            (AutoTransientTable.SimpleQuery): New. Implement the dependencies
1361            interface
1362            (TransientJoinedTable.__init__): Keep tack of the original table
1363            objects in addition to the corresponding transient tables.
1364    
1365            * Thuban/Model/table.py (DBFTable.Dependencies)
1366            (MemoryTable.Dependencies): New. Implement the dependencies
1367            interface
1368    
1369            * Thuban/Model/data.py (ShapeTable): New. Helper class for
1370            ShapefileStore
1371            (ShapefileStore.__init__): Use ShapeTable instead of
1372            AutoTransientTable
1373            (ShapefileStore.Table, ShapefileStore.Shapefile): Add doc-strings
1374            (ShapefileStore.FileName, ShapefileStore.FileType): New. Accessor
1375            methods for filename and type
1376            (ShapefileStore.Dependencies): New. Implement the dependencies
1377            interface
1378            (DerivedShapeStore): New class to replace SimpleStore. The main
1379            difference to SimpleStore is that it depends not on a shapefile
1380            but another shapestore which expresses the dependencies a bit
1381            better
1382            (SimpleStore.__init__): Add deprecation warning.
1383    
1384            * test/test_dbf_table.py (TestDBFTable.test_dependencies): New.

1389    
1390            * test/test_transientdb.py
1391            (TestTransientTable.test_auto_transient_table_dependencies): New.
1392            Test for the Dependencies method.
1393            (TestTransientTable.test_transient_joined_table): Add test for the
1394            Dependencies method.
1395    
1396            * test/test_session.py (TestSessionSimple.setUp)
1397            (TestSessionSimple.tearDown): New. Implement a better way to
1398            destroy the sessions.
1399            (TestSessionSimple.test_initial_state)
1400            (TestSessionSimple.test_add_table): Bind session to self.session
1401            so that it's destroyed by tearDown
1402            (TestSessionSimple.test_open_shapefile): New. Test for
1403            OpenShapefile and the object it returns
1404    
1405    2003-05-22  Bernhard Herzog  <[email protected]>
1406    
1407            * Thuban/Model/session.py (Session.AddTable): New method to
1408            register tables with the session.
1409            (Session.Tables): Return the tables registered with AddTable too.
1410    
1411            * test/test_session.py (TestSessionSimple.test_add_table): New.
1412            Test case for the AddTable method
1413    
1414    2003-05-22  Frank Koormann  <[email protected]>
1415    
1416            UI polishing updates: Place main buttons (OK, Cancel, etc) in the
1417            lower right corner, center labels for selections, initialize controls
1418            in reasonable order for keyboard navigation.
1419    
1420            * Thuban/UI/projdialog.py (ProjFrame.__init__, ProjFrame.__doLayout)
1421            (ProjFrame.__DoOnProjAvail): Determine position of current projection
1422            using the wxListBox.FindString() method. Still a problem (#1886)
1423    
1424            * Thuban/UI/classifier.py
1425            (Classifier.__init__, SelectPropertiesDialog.__init__)
1426    
1427            * Thuban/UI/classgen.py (ClassGenDialog.__init__,
1428            (ClassGenDialog.__DoOnGenTypeSelect): Moved initialization of the
1429            different classification types from here to __init__.
1430            (GenUniquePanel.__init__): Set the column width of the first field
1431            in the Field ListCtrl to the full width.
1432    
1433            * Thuban/UI/tableview.py (LayerTableFrame.__init__): Rename 'Save As'
1434            Button to 'Export'. Center Buttons in Selection Box, set Focus to
1435            Grid.
1436            (LayerTableFrame.OnKeyDown()): New, bound to the grid with EVT_KEY_DOWN,
1437            changes focus to the Selection when pressing "Alt-S".
1438    
1439            * Thuban/UI/legend.py (LegendTree.__SetVisibilityStyle): Only gray out
1440            the text if not visible. The italic font sometimes exceeds the
1441            rendering area.
1442    
1443    2003-05-21  Jonathan Coles   <[email protected]>
1444    
1445            * Thuban/UI/dock.py (DockFrame): Rename references to _OnClose
1446            to OnClose so that Thuban closes correctly.
1447    
1448            * Thuban/UI/mainwindow.py (MainWindow.OnClose): Call
1449            DockFrame.OnClose, not DockFrame._OnClose.
1450    
1451    2003-05-21  Jonathan Coles   <[email protected]>
1452    
1453            * Thuban/Model/classgen.py (ClassGenerator.GenQuantiles): Remove
1454            references to 'inf' and use new Range __init__ to pass floats
1455            directly rather than converting them to strings first.
1456            Fixes RTBug #1876.
1457    
1458            * Thuban/Model/classification.py (ClassGroupRange.SetRange):
1459            Use new Range ___init__ to pass floats.
1460    
1461            * Thuban/Model/layer.py (RasterLayer.__init__): Test if the
1462            filename is a valid image file. Throw IOError otherwise.
1463    
1464            * Thuban/Model/range.py: Brought over new Range from SciParam that
1465            is immutable and has an __init__ which can accept floats.
1466    
1467            * Thuban/UI/mainwindow.py (MainWindow.AddLayer): Move OpenShapefile
1468            into try block. AddLayer doesn't throw any exceptions anymore.
1469            (MainWindow.AddRasterLayer): Move constructor of RasterLayer into
1470            try block.
1471    
1472            * Thuban/UI/projdialog.py (GeoPanel.__init__): Put Degrees as
1473            the first item in choices. Fixes RTBug #1882.
1474    
1475            * Thuban/UI/renderer.py (MapRenderer.render_map): Check if scale
1476            has gone to 0 which is a serious problem. abort.
1477            (MapRenderer.draw_raster_layer): Catch IOError seperately and
1478            print the error from GDAL.
1479    
1480            * Thuban/UI/tableview.py (TableGrid.__init__): Call
1481            ToggleEventListeners to turn on listening.
1482            (TableGrid.ToggleEventListeners): New. Turns event listening on
1483            and off so as to prevent excessive messages.
1484            (LayerTableFrame.OnQuery): Use TableGrid.ToggleEventListeners
1485            to suppress excessive messages when selecting many rows.
1486            Fixes RTBug #1880.
1487    
1488            * Thuban/UI/view.py: Added checks against if scale == 0. This
1489            is a serious problem that can occur when an image without
1490            geo data is loading and causes the map projection bounds to
1491            go to infinity. Right now, the solution is to simply try
1492            to recover.
1493    
1494            * extensions/thuban/cpl_mfile.cpp (MFILEClose): Make sure
1495            to set the MFILEReceiver attributes even if the data is NULL.
1496    
1497            * extensions/thuban/gdalwarp.cpp: Improved the error handling
1498            and passed GDAL messages back up to the Python layer. Also
1499            tried to fix some memory leaks that were present in the original
1500            utility but didn't matter because the program aborted.
1501    
1502            * test/test_range.py: Copied over tests from SciParam. Removed
1503            tests against importing. Fixes RTBug #1867.
1504    
1505    2003-05-21  Bernhard Herzog  <[email protected]>
1506    
1507            * test/test_load.py: Remove unused imports and restructure the
1508            test code
1509            (LoadSessionTest): Split into one class for each test and turn
1510            LoadSessionTest itself into the base class for all such session
1511            tests.
1512            (ClassificationTest): New base class for load tests that test
1513            classifications
1514            (TestSingleLayer, TestLayerVisibility, TestClassification)
1515            (TestLabels, TestLayerProjection, TestRasterLayer): New classes
1516            for the individual tests
1517    
1518            * test/support.py (FileLoadTestCase.filename): New base class for
1519            file loading tests
1520    
1521    2003-05-21  Jan-Oliver Wagner <[email protected]>
1522    
1523            * Resources/Projections/defaults.proj: Renamed 'Universal Transverse
1524            Mercator' to 'UTM Zone 32' as a more convenient example.
1525            Added 'Gauss Krueger Zone 6'.
1526    
1527            * Data/iceland_sample_raster.thuban: political polygon now
1528            filled transparent to have the raster image visible at once.
1529    
1530    2003-05-21  Frank Koormann  <[email protected]>
1531    
1532            * Thuban/UI/mainwindow.py (MainWindow): Renamed _OnClose() back to
1533            OnClose() to keep in sync with extensions. Internally Thuban
1534            still uses "underscored" names.
1535    
1536    2003-05-20  Jonathan Coles   <[email protected]>
1537    
1538            This puts back Raster layer support. These layers support projections
1539            through the GDAL library. Currently, the CVS version is being used.
1540            There are no Debian packages available although this may change soon.
1541            A GDAL driver was extended to support writing to memory rather to
1542            files.
1543    
1544            There is still some work that needs to be done, such as some error
1545            handling when loading invalid images or when there is a problem
1546            projecting the image. This putback simply checks in the majority
1547            of the work.
1548    
1549            * setup.py: Add gdalwarp library extension.
1550    
1551            * Thuban/Model/layer.py (BaseLayer.HasClassification): New.
1552            Defaults to False, but can be overridden by subclasses if they
1553            support classification.
1554            (RasterLayer): New. Defines a new layer that represents an
1555            image.
1556    
1557            * Thuban/Model/load.py (SessionLoader.__init__): Add rasterlayer
1558            tag handler.
1559            (SessionLoader.start_layer): Encode the filename.
1560            (SessionLoader.start_rasterlayer, SessionLoader.end_rasterlayer):
1561            New. Supports reading a rasterlayer tag.
1562    
1563            * Thuban/Model/map.py (Map.BoundingBox): Fix typo in comment.
1564    
1565            * Thuban/Model/save.py (XMLWriter.encode): Don't assume that we
1566            get a string in Latin1. If we get such as string convert it to
1567            unicode first, otherwise leave if alone before encoding.
1568            (SessionSaver.write_layer): Add support for writing both Layers
1569            and RasterLayers.
1570    
1571            * Thuban/Model/transientdb.py (AutoTransientTable.SimpleQuery):
1572            The right argument may not be a string, it could also be a Column.
1573    
1574            * Thuban/UI/application.py (ThubanApplication.CreateMainWindow):
1575            Make initial window size 600x400. Fixes RTBug #1872.
1576    
1577            * Thuban/UI/classifier.py (Classifier.__init__): Rearrange how
1578            the dialog is constructed so that we can support layers that
1579            do not have classifications.
1580            (Classifier._OnTry): Only build a classification if the layer
1581            supports one.
1582    
1583            * Thuban/UI/legend.py: Change all checks that a layer is an
1584            instance of Layer into checks against BaseLayer.
1585            (LegendTree.__FillTreeLayer): Only add children to a branch if
1586            the layer supports classification.
1587    
1588            * Thuban/UI/mainwindow.py (MainWindow.NewSession,
1589            MainWindow.OpenSession): Don't proceed with an action if the
1590            user chooses Cancel when they are asked to save changes.
1591            (MainWindow.AddRasterLayer): New. Open a dialog to allow the
1592            user to select an image file. Create a new RasterLayer and add
1593            it to the map.
1594    
1595            * Thuban/UI/renderer.py (MapRenderer.render_map): Add support
1596            for rendering RasterLayer layers.
1597            (MapRenderer.draw_raster_layer): Actually method that calls
1598            the GDALWarp python wrapper and constructs an image from the
1599            data returned.
1600    
1601            * Thuban/UI/tableview.py (LayerTableFrame.__init__): Change the
1602            Choices symbols to match those used in the table query method.
1603            Replace deprecated method calls on table with new method names.
1604    
1605            * Thuban/UI/view.py (MapCanvas.set_view_transform): Try to limit
1606            how small the scale can get. This still needs more testing.
1607    
1608            * extensions/thuban/bmpdataset.cpp: New, but copied from GDAL.
1609            Provides a driver to output in .bmp format.
1610    
1611            * extensions/thuban/cpl_mfile.cpp, extensions/thuban/cpl_mfile.h:
1612            New. Provides IO routines which write to memory, rather than a file.
1613    
1614            * extensions/thuban/gdalwarp.cpp: New, but basically a direct copy
1615            of the gdalwarp utility provided in GDAL. Added function calls
1616            that can be accessed from python.
1617    
1618            * Data/iceland_sample_raster.thuban: New. Sample file that uses
1619            a raster layer.
1620    
1621            * Data/iceland/island.tfw, Data/iceland/island.tif: New. Raster
1622            layer image data.
1623    
1624            * Doc/thuban.dtd: Added rasterlayer attribute definition.
1625    
1626            * test/test_layer.py, test/test_load.py, test/test_save.py: Added
1627            tests associated with the raster layer code.
1628    
1629            * test/test_transientdb.py
1630            (TestTransientTable.test_auto_transient_table_query): Added a test
1631            for using a Column object as the "right" parameter to a query.
