Avoid warnings when run under Python 2.3 |
| 4 |
|
|
| 5 |
|
* Thuban/UI/baserenderer.py (BaseRenderer.draw_point_shape) |
| 6 |
|
(BaseRenderer.draw_label_layer): Coordinates must be ints. |
| 7 |
|
|
| 8 |
|
* Thuban/UI/renderer.py (MapRenderer.make_point): Turn this into a |
| 9 |
|
real method so that we can convert to int. |
| 10 |
|
(MapRenderer.label_font): The font size mist be an int. |
| 11 |
|
|
| 12 |
|
* Thuban/UI/common.py (Color2wxColour): The color values must be |
| 13 |
|
ints. Also, remove the unnecessary asserts. |
| 14 |
|
|
| 15 |
|
* test/test_load_0_8.py (TestUnicodeStrings.file_contents) |
| 16 |
|
(TestUnicodeStrings.test): Python source code should not contain |
| 17 |
|
non-ascii characters unless an encoding is specified in the file. |
| 18 |
|
Therefore use \x escapes in the string literals for non-ascii |
| 19 |
|
characters. |

|
|
| 23 |
|
* Thuban/Model/resource.py (get_system_proj_file): Add a filename |
| 24 |
|
parameter so that this function can be used for all proj files in |
| 25 |
|
Resource/Projections |
| 26 |
|
(DEFAULT_PROJ_FILE, EPSG_PROJ_FILE): New. Predefined filenames for |
| 27 |
|
get_system_proj_file |
| 28 |
|
|
| 29 |
|
* Thuban/UI/projdialog.py (ProjFrame.__init__): Instead of one |
| 30 |
|
ProjFile self.__sysProjFile use a dictionary of system ProjFile |
| 31 |
|
objects self._sys_proj_files |
| 32 |
|
(ProjFrame.build_dialog): Adapt to the new changes in the |
| 33 |
|
ProjectionList constructor. Add a check button to toggle whether |
| 34 |
|
EPSG projections are shown |
| 35 |
|
(ProjFrame._OnShowEPSG): New. Handler for the epsg check button |
| 36 |
|
events. |
| 37 |
|
(ProjFrame.load_user_proj, ProjFrame.load_system_proj): Only show |
| 38 |
|
the busy cursor if the files have not yet been loaded by the |
| 39 |
|
dialog. |
| 40 |
|
(ProjFrame.load_system_proj): Add a parameter for the name of the |
| 41 |
|
proj file. Maintain the dictionary of system projections |
| 42 |
|
self._sys_proj_files |
| 43 |
|
|
| 44 |
|
* Thuban/UI/projlist.py (ProjectionList): Merge the system_projs, |
| 45 |
|
user_projs parameters into one parameter proj_files which is a |
| 46 |
|
list of proj files. |
| 47 |
|
(ProjectionList._subscribe_proj_files) |
| 48 |
|
(ProjectionList._unsubscribe_proj_files): New. Move |
| 49 |
|
subscription/unsubscription of projfile messages to separate |
| 50 |
|
methods |
| 51 |
|
(ProjectionList.Destroy): The unsubscribe is now done in |
| 52 |
|
_unsubscribe_proj_files |
| 53 |
|
(ProjectionList.update_projections): We now have a list of proj |
| 54 |
|
file objects |
| 55 |
|
(ProjectionList.SetProjFiles): New method to set a new list of |
| 56 |
|
proj file objects |
| 57 |
|
|
| 58 |
|
* test/test_proj.py (ProjFileReadTests.test_get_system_proj_file): |
| 59 |
|
Specify explicitly which system proj file to load. |
| 60 |
|
|
| 61 |
|
2003-11-11 Bernhard Herzog <[email protected]> |
| 62 |
|
|
| 63 |
|
* Thuban/Model/load.py (SessionLoader.Destroy): New. Clear all |
| 64 |
|
instance variables to cut cyclic references. The GC would have |
| 65 |
|
collected the loader eventually but it can happen that it doesn't |
| 66 |
|
run at all until thuban is closed (2.3 but not 2.2 tries a bit |
| 67 |
|
harder and forces a collection when the interpreter terminates) |
| 68 |
|
(load_session): Call the handler's Destroy method to make sure |
| 69 |
|
that it gets garbage collected early. Otherwise it will be |
| 70 |
|
collected very late if at all and it holds some references to e.g. |
| 71 |
|
shapestores and the session which can lead to leaks (of e.g. the |
| 72 |
|
temporary files) |
| 73 |
|
|
| 74 |
|
* test/test_load.py (TestSingleLayer.test_leak): New. test for the |
| 75 |
|
resource leak in load_session |
| 76 |
|
|
| 77 |
|
2003-11-10 Bernhard Herzog <[email protected]> |
| 78 |
|
|
| 79 |
|
* Thuban/UI/baserenderer.py: Add a way to specify how layers in |
| 80 |
|
extensions are to be rendered. |
| 81 |
|
(_renderer_extensions): New. List with renderer for layers in |
| 82 |
|
extensions |
| 83 |
|
(add_renderer_extension): New. Add a renderer extension |
| 84 |
|
(init_renderer_extensions): New. Init the renderer extensions |
| 85 |
|
(BaseRenderer.render_map_incrementally): Search |
| 86 |
|
_renderer_extensions for how to draw unknown layer types |
| 87 |
|
(BaseRenderer.draw_raster_data): Add format parameter so that |
| 88 |
|
formats other than BMP can be drawn |
| 89 |
|
(BaseRenderer.draw_raster_layer): Pass an explicit format to |
| 90 |
|
draw_raster_data |
| 91 |
|
|
| 92 |
|
* Thuban/UI/renderer.py (raster_format_map): New. Mapping form the |
| 93 |
|
strings of the format parameter of draw_raster_data method to wx |
| 94 |
|
constants |
| 95 |
|
(MapRenderer.draw_raster_data): Add the format parameter and use |
| 96 |
|
raster_format_map to map it to the right wxwindows constant for |
| 97 |
|
wxImageFromStream |
| 98 |
|
|
| 99 |
|
* test/test_baserenderer.py (SimpleRenderer.draw_raster_data): Add |
| 100 |
|
the format parameter and record it |
| 101 |
|
(TestBaseRenderer.test_raster_no_projection): check the format |
| 102 |
|
paramter of the draw_raster_data method |
| 103 |
|
(TestBaseRenderer.test_renderer_extension): New. Test the renderer |
| 104 |
|
extension facility |
| 105 |
|
|

|
Tweak the usage of the sqlite database to make common use cases |
| 109 |
|
more responsive. In most cases copying the data to the sqlite |
| 110 |
|
database takes so long that using sqlite doesn't have enough |
| 111 |
|
advantages. |
| 112 |
|
|
| 113 |
|
* Thuban/Model/transientdb.py (TransientTableBase.ValueRange): Add |
| 114 |
|
comments about performance and query the min and max in separate |
| 115 |
|
statements because only that way will indexes be used. |
| 116 |
|
(TransientTableBase.UniqueValues): Add some comments about |
| 117 |
|
performance. |
| 118 |
|
(AutoTransientTable.ValueRange, AutoTransientTable.UniqueValues): |
| 119 |
|
Do not copy the data to the transient DB but use the transient |
| 120 |
|
copy if it exists. See the new comments for the performance trade |
| 121 |
|
offs |
| 122 |
|
|
| 123 |
|
* test/test_transientdb.py |
| 124 |
|
(TestTransientTable.test_auto_transient_table): Make sure that the |
| 125 |
|
data is copied to the transient database at some point. |
| 126 |
|

|
|
| 129 |
|
* Thuban/Model/data.py (ShapefileStore.ShapesInRegion): Bind some |
| 130 |
|
globals to locals so that it's a bit faster |
| 131 |
|
|
| 132 |
|
2003-11-03 Bernhard Herzog <[email protected]> |
| 133 |
|
|
| 134 |
|
* Thuban/UI/baserenderer.py |
| 135 |
|
(BaseRenderer.draw_shape_layer_incrementally): Use the ReadValue |
| 136 |
|
method. ReadValue is faster than ReadRowAsDict since it only reads |
| 137 |
|
one cell especially now that the dbf file objects actually |
| 138 |
|
implement it. |
| 139 |
|
|
| 140 |
|
* Thuban/Model/table.py (DBFTable.ReadValue): Use the new |
| 141 |
|
read_attribute method of the dbf objects |
| 142 |
|
|
| 143 |
