# Line 1  Line 1 
1    2003-11-25  Bernhard Herzog  <[email protected]>
2    
3            * test/test_load.py (TestClassification.test): Add the missing
4            round trip test.
5            (TestClassification.file_contents): Update to the newest file
6            format
7    
8    2003-11-25  Bernhard Herzog  <[email protected]>
9    
10            Add very experimental (and possibly dangerous) extension to draw
11            polygons:
12    
13            * Extensions/drawshape/README: New. Brief installation
14            instructions
15    
16            * Extensions/drawshape/drawshape.py: New. Implementation of the
17            drawshape extensions
18    
19            * Extensions/drawshape/patch.diff: Patch to apply before the
20            extension can be used.
21    
22    2003-11-24  Bernhard Herzog  <[email protected]>
23    
24            * Thuban/Model/data.py (ShapefileStore._open_shapefile)
25            (ShapefileStore.__init__): Factor opening the shapefile into a
26            separate method (the new _open_shapefile). This makes the code a
27            bit more readable but the real reason is that it makes some evil
28            hacks easier. :-)
29    
30    2003-11-24  Bernhard Herzog  <[email protected]>
31    
32            * Thuban/Model/load.py (SessionLoader.check_attrs): If no
33            converter is specified for an attribute assume it's a string
34            containing only Latin1 characters. Update doc-string accordingly.
35            This change should fix many places where unicode objects might
36            accidentally enter Thuban.
37    
38            * test/test_load.py (TestNonAsciiColumnName): New test to check
39            what happens with column names in DBF files that contain non-ascii
40            characters
41    
42    2003-11-21  Bernhard Herzog  <[email protected]>
43    
44            Enable the experimental attribute editing again and introduce a
45            command line switch to actually activate it
46    
47            * Thuban/UI/main.py (options): New. Container for options set on
48            the commmand line
49            (main): Add the --enable-attribute-editing flag.
50    
51            * Thuban/UI/identifyview.py (IdentifyView.__init__): If attribute
52            editing is enabled use the grid ctrl which allows editing of the
53            values
54    
55            * Thuban/Model/transientdb.py (AutoTransientTable.write_record):
56            New. Just delegate this to the underlying table.
57    
58    2003-11-20  Bernhard Herzog  <[email protected]>
59    
60            * test/test_proj.py (ProjFileReadTests.test_read_unreadable_file):
61            Skip this test if run under non-posix systems since it only works
62            there
63    
64    2003-11-19  Bernhard Herzog  <[email protected]>
65    
66            * Thuban/Model/resource.py: Rework the way gdal support is
67            determined so that we can give a reason in the about why gdal is
68            not supported.
69            (gdal_support_status): New. Variable holding a string with the
70            reason for no gdal support
71    
72            * Thuban/UI/about.py (About.__init__): Add the reason why gdal is
73            not supported to the message
74    
75    2003-11-19  Bernhard Herzog  <[email protected]>
76    
77            Remove the old table interface and its test cases
78    
79            * Thuban/Model/table.py (OldTableInterfaceMixin): Removed.
80            (DBFTable, MemoryTable): Do not derive from OldTableInterfaceMixin
81            anymore
82    
83            * Thuban/Model/transientdb.py (TransientTableBase)
84            (AutoTransientTable): Do not derive from OldTableInterfaceMixin
85            anymore
86    
87            * test/test_table.py: Removed since the old interface it tests is
88            gone.
89    
90            * test/runtests.py (main): The old table interface is gone and
91            with it the deprecation warnings so remove the code that turns
92            these warnings into errors
93    
94    2003-11-19  Bernhard Herzog  <[email protected]>
95    
96            * test/test_table.py: Revert to revision 1.5 again. Changing the
97            tests to use the new table interface is completely wrong since the
98            whole purpose of the tests in this module is to test the old
99            interface.
100

108            (DBFrame.OnAdd): Use the new MatchesParameters method when looking
109            for existing connections with the same parameters and break out of
110            the loop correctly.
111    
112            * test/test_postgis_db.py (TestBriefDescription)
113            (TestPostGISSimple.test_brief_description): Rename
114            TestBriefDescription to TestPostGISSimple and the test method to
115            test_brief_description so that we can add more test methods.
116            (TestPostGISSimple.test_matches_parameters): New. Test the new
117            MatchesParameters method
118    
119    2003-11-18  Bernhard Herzog  <[email protected]>
120    
121            * Thuban/Lib/connector.py (Publisher): Introduce a new flag,
122            _was_destroyed, to indicate whether an publisher instance has
123            already been destroyed.
124            (Publisher.Unsubscribe): Only disconnect if the publisher has not
125            been destroyed yet.

155    
156            * test/test_postgis_db.py (TestPostGISSpecialCases)
157            (TestPostGISIgnoredColumns): Rename the class to
158            TestPostGISSpecialCases because that better describes the new
159            cases
160            (TestPostGISSpecialCases.test_unsupported_types)
161            (TestPostGISSpecialCases.test): Rename the method to
162            test_unsupported_types because we need a more descriptive name now
163            that there are more methods
164            (TestPostGISSpecialCases.test_table_name_quoting)

187    
188            * Thuban/UI/projdialog.py (ProjFrame.build_dialog): Add a space

191            (ProjFrame._OnShowEPSG): Handle the deprecated EPSG projections
192            too

200    
201            * Thuban/UI/renderer.py (MapRenderer.make_point): Turn this into a

208            * test/test_load_0_8.py (TestUnicodeStrings.file_contents)
209            (TestUnicodeStrings.test): Python source code should not contain
210            non-ascii characters unless an encoding is specified in the file.
211            Therefore use \x escapes in the string literals for non-ascii
212            characters.
213    
214    2003-11-11  Bernhard Herzog  <[email protected]>
215    
216            * Thuban/Model/resource.py (get_system_proj_file): Add a filename

220            get_system_proj_file
221    
222            * Thuban/UI/projdialog.py (ProjFrame.__init__): Instead of one
223            ProjFile self.__sysProjFile use a dictionary of system ProjFile
224            objects self._sys_proj_files
225            (ProjFrame.build_dialog): Adapt to the new changes in the
226            ProjectionList constructor. Add a check button to toggle whether
227            EPSG projections are shown

229            events.
230            (ProjFrame.load_user_proj, ProjFrame.load_system_proj): Only show
231            the busy cursor if the files have not yet been loaded by the
232            dialog.
233            (ProjFrame.load_system_proj): Add a parameter for the name of the
234            proj file. Maintain the dictionary of system projections
235            self._sys_proj_files
236

255    
256            * Thuban/Model/load.py (SessionLoader.Destroy): New. Clear all
257            instance variables to cut cyclic references. The GC would have
258            collected the loader eventually but it can happen that it doesn't
259            run at all until thuban is closed (2.3 but not 2.2 tries a bit
260            harder and forces a collection when the interpreter terminates)
261            (load_session): Call the handler's Destroy method to make sure
262            that it gets garbage collected early. Otherwise it will be
263            collected very late if at all and it holds some references to e.g.
264            shapestores and the session which can lead to leaks (of e.g. the
265            temporary files)
266    
267            * test/test_load.py (TestSingleLayer.test_leak): New. test for the
268            resource leak in load_session
269    
270    2003-11-10  Bernhard Herzog  <[email protected]>
271    
272            * Thuban/UI/baserenderer.py: Add a way to specify how layers in
273            extensions are to be rendered.
274            (_renderer_extensions): New. List with renderer for layers in
275            extensions
276            (add_renderer_extension): New. Add a renderer extension
277            (init_renderer_extensions): New. Init the renderer extensions
278            (BaseRenderer.render_map_incrementally): Search
279            _renderer_extensions for how to draw unknown layer types
280            (BaseRenderer.draw_raster_data): Add format parameter so that
281            formats other than BMP can be drawn
282            (BaseRenderer.draw_raster_layer): Pass an explicit format to
283            draw_raster_data
284    
285            * Thuban/UI/renderer.py (raster_format_map): New. Mapping form the
286            strings of the format parameter of draw_raster_data method to wx
287            constants
288            (MapRenderer.draw_raster_data): Add the format parameter and use
289            raster_format_map to map it to the right wxwindows constant for
290            wxImageFromStream
291    
292            * test/test_baserenderer.py (SimpleRenderer.draw_raster_data): Add
293            the format parameter and record it
294            (TestBaseRenderer.test_raster_no_projection): check the format
295            paramter of the draw_raster_data method
296            (TestBaseRenderer.test_renderer_extension): New. Test the renderer
297            extension facility
298    
299    2003-11-07  Bernhard Herzog  <[email protected]>
300    
301            Tweak the usage of the sqlite database to make common use cases
302            more responsive. In most cases copying the data to the sqlite
303            database takes so long that using sqlite doesn't have enough
304            advantages.
305    
306            * Thuban/Model/transientdb.py (TransientTableBase.ValueRange): Add
307            comments about performance and query the min and max in separate
308            statements because only that way will indexes be used.
309            (TransientTableBase.UniqueValues): Add some comments about
310            performance.
311            (AutoTransientTable.ValueRange, AutoTransientTable.UniqueValues):
312            Do not copy the data to the transient DB but use the transient
313            copy if it exists. See the new comments for the performance trade
314            offs
315    
316            * test/test_transientdb.py
317            (TestTransientTable.test_auto_transient_table): Make sure that the
318            data is copied to the transient database at some point.
319    
320    2003-11-03  Bernhard Herzog  <[email protected]>
321    
322            * Thuban/Model/data.py (ShapefileStore.ShapesInRegion): Bind some
323            globals to locals so that it's a bit faster
324    
325    2003-11-03  Bernhard Herzog  <[email protected]>
326    
327            * Thuban/UI/baserenderer.py
328            (BaseRenderer.draw_shape_layer_incrementally): Use the ReadValue
329            method. ReadValue is faster than ReadRowAsDict since it only reads
330            one cell especially now that the dbf file objects actually
331            implement it.
332    
333            * Thuban/Model/table.py (DBFTable.ReadValue): Use the new
334            read_attribute method of the dbf objects
335    
336    2003-11-03  Bernhard Herzog  <[email protected]>
337    
338            * Extensions/profiling/profiling.py (popup_dialog_box): New config
339            variable to indicate whether the result should be shown in a
340            dialog box
341            (profile_screen_renderer, time_screen_renderer): Only show a
342            dialog box if popup_dialog_box is true.
343            (profile_screen_renderer): Flush stdout after the printing the
344            first part of the "profiling..." message
345    
346            * Thuban/UI/baserenderer.py
347            (BaseRenderer.draw_shape_layer_incrementally): Cache the pens and
348            brushes for the groups so that they're not created over and over
349            again
350    
351            * Thuban/Model/classification.py (Classification.__getattr__)
352            (Classification._compile_classification)
353            (Classification._clear_compiled_classification): New. Methods to
354            manage a 'compiled' representation of the classification groups
355            which is created on demand
356            (Classification.InsertGroup, Classification.RemoveGroup)
357            (Classification.ReplaceGroup): reset the compiled representation
358            (Classification.FindGroup): Use the compiled representation to
359            find the matching group
360            (ClassGroupRange.GetRangeTuple): New. Return the range as a tuple
361    
362    2003-10-31  Bernhard Herzog  <[email protected]>
363    
364            * Thuban/Model/classification.py (Classification.SetDefaultGroup):
365            Send a CLASS_CHANGED message
366            (Classification.RemoveGroup): Send a CLASS_CHANGED message and do
367            not return the removed group since it wasn't used.
368    
369            * test/test_classification.py
370            (TestClassification.test_set_default_group): New. Test the
371            SetDefaultGroup method
372            (TestClassification.test_insert_group): New. Test the InsertGroup
373            method
374            (TestClassification.test_remove_group): New. Test the RemoveGroup
375            method
376            (TestClassification.test_replace_group): New. Test the
377            ReplaceGroup method
378    
379    2003-10-31  Bernhard Herzog  <[email protected]>
380    
381            * test/test_classification.py (TestClassification.setUp):
382            Subscribe to the CLASS_CHANGED messages
383            (TestClassification.tearDown): New. Destroy the classification
384            properly
385            (TestClassification.test_defaults): Add tests for the default line
386            width and whether no messages were sent yet
387            (TestClassification.test_set_default_properties): Add tests for
388            messages and setting the default line width

396    
397            * test/test_classification.py (TestClassification.setUp): New.
