1    2003-11-27  Bernhard Herzog  <[email protected]>
2    
3            Corect some bounding box projection problems
4    
5            * Thuban/Model/proj.py (Projection.InverseBBox): New. Inverse
6            version of ForwardBBox
7            (Projection._transform_bbox): New. common implementation of
8            ForwardBBox and InverseBBox
9            (Projection.ForwardBBox): Use _transform_bbox.
10    
11            * test/test_proj.py (TestProjection.test): Add test for
12            InverseBBox
13    
14            * Thuban/Model/layer.py (Layer.LatLongBoundingBox)
15            (Layer.ShapesBoundingBox, RasterLayer.LatLongBoundingBox): Use the
16            new InverseBBox method to determine the unprojected bounding box
17            (Layer.ShapesInRegion): Use the ForwardBBox method to project the
18            bbox.
19    
20            * test/test_layer.py (TestLayer.test_point_layer_with_projection):
21            Removed.
22            (TestLayer.test_arc_layer_with_projection): New. This test is
23            better able to test whether bounding boxes are projected correctly
24            than test_point_layer_with_projection
25    
26    2003-11-25  Bernhard Herzog  <[email protected]>
27    
28            * Thuban/UI/about.py (About.__init__): Make sure we have ASCII
29            source code.
30    
31    2003-11-25  Bernhard Herzog  <[email protected]>
32    
33            * Thuban/Model/layer.py (Layer.__getattr__): Removed. It was only
34            there for backwards compatibility and all code relying on that
35            should have been updated by now.
36    
37    2003-11-25  Bernhard Herzog  <[email protected]>
38    
39            * test/test_load.py (TestClassification.test): Add the missing
40            round trip test.
41            (TestClassification.file_contents): Update to the newest file
42            format
43    
44    2003-11-25  Bernhard Herzog  <[email protected]>
45    
46            Add very experimental (and possibly dangerous) extension to draw
47            polygons:
48    
49            * Extensions/drawshape/README: New. Brief installation
50            instructions
51    
52            * Extensions/drawshape/drawshape.py: New. Implementation of the
53            drawshape extensions
54    
55            * Extensions/drawshape/patch.diff: Patch to apply before the
56            extension can be used.
57    
58    2003-11-24  Bernhard Herzog  <[email protected]>
59    
60            * Thuban/Model/data.py (ShapefileStore._open_shapefile)
61            (ShapefileStore.__init__): Factor opening the shapefile into a
62            separate method (the new _open_shapefile). This makes the code a
63            bit more readable but the real reason is that it makes some evil
64            hacks easier. :-)
65    
66    2003-11-24  Bernhard Herzog  <[email protected]>
67    
68            * Thuban/Model/load.py (SessionLoader.check_attrs): If no
69            converter is specified for an attribute assume it's a string
70            containing only Latin1 characters. Update doc-string accordingly.
71            This change should fix many places where unicode objects might
72            accidentally enter Thuban.
73    
74            * test/test_load.py (TestNonAsciiColumnName): New test to check
75            what happens with column names in DBF files that contain non-ascii
76            characters
77    
78    2003-11-21  Bernhard Herzog  <[email protected]>
79    
80            Enable the experimental attribute editing again and introduce a
81            command line switch to actually activate it
82    
83            * Thuban/UI/main.py (options): New. Container for options set on
84            the commmand line
85            (main): Add the --enable-attribute-editing flag.
86    
87            * Thuban/UI/identifyview.py (IdentifyView.__init__): If attribute
88            editing is enabled use the grid ctrl which allows editing of the
89            values
90    
91            * Thuban/Model/transientdb.py (AutoTransientTable.write_record):
92            New. Just delegate this to the underlying table.
93    
94    2003-11-20  Bernhard Herzog  <[email protected]>
95    
96            * test/test_proj.py (ProjFileReadTests.test_read_unreadable_file):
97            Skip this test if run under non-posix systems since it only works
98            there
99    
100    2003-11-19  Bernhard Herzog  <[email protected]>
101    
102            * Thuban/Model/resource.py: Rework the way gdal support is
103            determined so that we can give a reason in the about why gdal is
104            not supported.
105            (gdal_support_status): New. Variable holding a string with the
106            reason for no gdal support
107    
108            * Thuban/UI/about.py (About.__init__): Add the reason why gdal is
109            not supported to the message
110    
111    2003-11-19  Bernhard Herzog  <[email protected]>
112    
113            Remove the old table interface and its test cases
114    
115            * Thuban/Model/table.py (OldTableInterfaceMixin): Removed.
116            (DBFTable, MemoryTable): Do not derive from OldTableInterfaceMixin
117            anymore
118    
119            * Thuban/Model/transientdb.py (TransientTableBase)
120            (AutoTransientTable): Do not derive from OldTableInterfaceMixin
121            anymore
122    
123            * test/test_table.py: Removed since the old interface it tests is
124            gone.
125    
126            * test/runtests.py (main): The old table interface is gone and
127            with it the deprecation warnings so remove the code that turns
128            these warnings into errors
129    
130    2003-11-19  Bernhard Herzog  <[email protected]>
131    
132            * test/test_table.py: Revert to revision 1.5 again. Changing the
133            tests to use the new table interface is completely wrong since the
134            whole purpose of the tests in this module is to test the old
135            interface.

146            the loop correctly.
147    
148            * test/test_postgis_db.py (TestBriefDescription)
149            (TestPostGISSimple.test_brief_description): Rename
150            TestBriefDescription to TestPostGISSimple and the test method to
151            test_brief_description so that we can add more test methods.

153            MatchesParameters method
154    
155    2003-11-18  Bernhard Herzog  <[email protected]>
156    
157            * Thuban/Lib/connector.py (Publisher): Introduce a new flag,
158            _was_destroyed, to indicate whether an publisher instance has
159            already been destroyed.

191    
192            * test/test_postgis_db.py (TestPostGISSpecialCases)
193            (TestPostGISIgnoredColumns): Rename the class to
194            TestPostGISSpecialCases because that better describes the new
195            cases
196            (TestPostGISSpecialCases.test_unsupported_types)
197            (TestPostGISSpecialCases.test): Rename the method to
198            test_unsupported_types because we need a more descriptive name now
199            that there are more methods
200            (TestPostGISSpecialCases.test_table_name_quoting)

223    
224            * Thuban/UI/projdialog.py (ProjFrame.build_dialog): Add a space

226            eps projections and a label for the epsg widgets
227            (ProjFrame._OnShowEPSG): Handle the deprecated EPSG projections
228            too

236    
237            * Thuban/UI/renderer.py (MapRenderer.make_point): Turn this into a

243    
244            * test/test_load_0_8.py (TestUnicodeStrings.file_contents)
245            (TestUnicodeStrings.test): Python source code should not contain
246            non-ascii characters unless an encoding is specified in the file.
247            Therefore use \x escapes in the string literals for non-ascii
248            characters.
249    
250    2003-11-11  Bernhard Herzog  <[email protected]>
251    
252            * Thuban/Model/resource.py (get_system_proj_file): Add a filename

255            (DEFAULT_PROJ_FILE, EPSG_PROJ_FILE): New. Predefined filenames for
256            get_system_proj_file
257    
258            * Thuban/UI/projdialog.py (ProjFrame.__init__): Instead of one
259            ProjFile self.__sysProjFile use a dictionary of system ProjFile
260            objects self._sys_proj_files
261            (ProjFrame.build_dialog): Adapt to the new changes in the
262            ProjectionList constructor. Add a check button to toggle whether
263            EPSG projections are shown
264            (ProjFrame._OnShowEPSG): New. Handler for the epsg check button
265            events.
266            (ProjFrame.load_user_proj, ProjFrame.load_system_proj): Only show
267            the busy cursor if the files have not yet been loaded by the
268            dialog.
269            (ProjFrame.load_system_proj): Add a parameter for the name of the
270            proj file. Maintain the dictionary of system projections
271            self._sys_proj_files
272    
273            * Thuban/UI/projlist.py (ProjectionList): Merge the system_projs,

291    
292            * Thuban/Model/load.py (SessionLoader.Destroy): New. Clear all
293            instance variables to cut cyclic references. The GC would have
294            collected the loader eventually but it can happen that it doesn't
295            run at all until thuban is closed (2.3 but not 2.2 tries a bit
296            harder and forces a collection when the interpreter terminates)
297            (load_session): Call the handler's Destroy method to make sure
298            that it gets garbage collected early. Otherwise it will be
299            collected very late if at all and it holds some references to e.g.
300            shapestores and the session which can lead to leaks (of e.g. the
301            temporary files)
302    
303            * test/test_load.py (TestSingleLayer.test_leak): New. test for the
304            resource leak in load_session
305    
306    2003-11-10  Bernhard Herzog  <[email protected]>
307    
308            * Thuban/UI/baserenderer.py: Add a way to specify how layers in
309            extensions are to be rendered.
310            (_renderer_extensions): New. List with renderer for layers in
311            extensions
312            (add_renderer_extension): New. Add a renderer extension
313            (init_renderer_extensions): New. Init the renderer extensions
314            (BaseRenderer.render_map_incrementally): Search
315            _renderer_extensions for how to draw unknown layer types
316            (BaseRenderer.draw_raster_data): Add format parameter so that
317            formats other than BMP can be drawn
318            (BaseRenderer.draw_raster_layer): Pass an explicit format to
319            draw_raster_data
320    
321            * Thuban/UI/renderer.py (raster_format_map): New. Mapping form the
322            strings of the format parameter of draw_raster_data method to wx
323            constants
324            (MapRenderer.draw_raster_data): Add the format parameter and use
325            raster_format_map to map it to the right wxwindows constant for
326            wxImageFromStream
327    
328            * test/test_baserenderer.py (SimpleRenderer.draw_raster_data): Add
329            the format parameter and record it
330            (TestBaseRenderer.test_raster_no_projection): check the format
331            paramter of the draw_raster_data method
332            (TestBaseRenderer.test_renderer_extension): New. Test the renderer
333            extension facility
334    
335    2003-11-07  Bernhard Herzog  <[email protected]>
336    
337            Tweak the usage of the sqlite database to make common use cases
338            more responsive. In most cases copying the data to the sqlite
339            database takes so long that using sqlite doesn't have enough
340            advantages.
341    
342            * Thuban/Model/transientdb.py (TransientTableBase.ValueRange): Add
343            comments about performance and query the min and max in separate
344            statements because only that way will indexes be used.
345            (TransientTableBase.UniqueValues): Add some comments about
346            performance.
347            (AutoTransientTable.ValueRange, AutoTransientTable.UniqueValues):
348            Do not copy the data to the transient DB but use the transient
349            copy if it exists. See the new comments for the performance trade
350            offs
351    
352            * test/test_transientdb.py
353            (TestTransientTable.test_auto_transient_table): Make sure that the
354            data is copied to the transient database at some point.
355    
356    2003-11-03  Bernhard Herzog  <[email protected]>
357    
358            * Thuban/Model/data.py (ShapefileStore.ShapesInRegion): Bind some
359            globals to locals so that it's a bit faster
360    
361    2003-11-03  Bernhard Herzog  <[email protected]>
362    
363            * Thuban/UI/baserenderer.py
364            (BaseRenderer.draw_shape_layer_incrementally): Use the ReadValue
365            method. ReadValue is faster than ReadRowAsDict since it only reads
366            one cell especially now that the dbf file objects actually
367            implement it.
368    
369            * Thuban/Model/table.py (DBFTable.ReadValue): Use the new
370            read_attribute method of the dbf objects
371    
372    2003-11-03  Bernhard Herzog  <[email protected]>
373    
374            * Extensions/profiling/profiling.py (popup_dialog_box): New config
375            variable to indicate whether the result should be shown in a
376            dialog box
377            (profile_screen_renderer, time_screen_renderer): Only show a
378            dialog box if popup_dialog_box is true.
379            (profile_screen_renderer): Flush stdout after the printing the
380            first part of the "profiling..." message
381    
382            * Thuban/UI/baserenderer.py
383            (BaseRenderer.draw_shape_layer_incrementally): Cache the pens and
384            brushes for the groups so that they're not created over and over
385            again
386    
387            * Thuban/Model/classification.py (Classification.__getattr__)
388            (Classification._compile_classification)
389            (Classification._clear_compiled_classification): New. Methods to
390            manage a 'compiled' representation of the classification groups
391            which is created on demand
392            (Classification.InsertGroup, Classification.RemoveGroup)
393            (Classification.ReplaceGroup): reset the compiled representation
394            (Classification.FindGroup): Use the compiled representation to
395            find the matching group
396            (ClassGroupRange.GetRangeTuple): New. Return the range as a tuple
397    
398    2003-10-31  Bernhard Herzog  <[email protected]>
