|
Next step of table implementation. Introduce a transient database |
| 4 |
|
using SQLite that some of the data is copied to on demand. This |
| 5 |
|
allows us to do joins and other operations that require an index |
| 6 |
|
for good performance with reasonable efficiency. Thuban now needs |
| 7 |
|
SQLite 2.8.0 and pysqlite 0.4.1. Older versions may work but I |
| 8 |
|
haven't tested that. |
| 9 |
|
|
| 10 |
|
* Thuban/Model/transientdb.py: New. Transient database |
| 11 |
|
implementation. |
| 12 |
|
|
| 13 |
|
* test/test_transientdb.py: New. Tests for the transient DB |
| 14 |
|
classes. |
| 15 |
|
|
| 16 |
|
* Thuban/Model/session.py (AutoRemoveFile, AutoRemoveDir): New |
| 17 |
|
classes to help automatically remove temporary files and |
| 18 |
|
directories. |
| 19 |
|
(Session.__init__): New instance variables temp_dir for the |
| 20 |
|
temporary directory and transient_db for the SQLite database |
| 21 |
|
(Session.temp_directory): New. Create a temporary directory if not |
| 22 |
|
yet done and return its name. Use AutoRemoveDir to have it |
| 23 |
|
automatically deleted |
| 24 |
|
(Session.TransientDB): Instantiate the transient database if not |
| 25 |
|
done yet and return it. |
| 26 |
|
|
| 27 |
|
* Thuban/Model/data.py (ShapefileStore.__init__): Use an |
| 28 |
|
AutoTransientTable so that data is copied to the transient DB on |
| 29 |
|
demand. |
| 30 |
|
(SimpleStore): New class that simply combines a table and a |
| 31 |
|
shapefile |
| 32 |
|
|
| 33 |
|
* Thuban/Model/table.py (Table, DBFTable): Rename Table into |
| 34 |
|
DBFTable and update its doc-string to reflect the fact that this |
| 35 |
|
is only the table interface to a DBF file. Table is now an alias |
| 36 |
|
for DBFTable for temporary backwards compatibility. |
| 37 |
|
|
| 38 |
|
* Thuban/UI/application.py (ThubanApplication.OnExit): Make sure |
| 39 |
|
the last reference to the session goes away so that the temporary |
| 40 |
|
files are removed properly. |
| 41 |
|
|
| 42 |
|
* test/test_load.py (LoadSessionTest.tearDown): Remove the |
| 43 |
|
reference to the session to make sure the temporary files are |
| 44 |
|
removed. |
| 45 |
|
|
| 46 |
|
2003-04-29 Bernhard Herzog <[email protected]> |
| 47 |
|
|
| 48 |
|
* Thuban/Model/load.py (XMLReader.__init__, XMLReader.read): Turn |
| 49 |
|
the __parser instance variable into a normal local variable in |
| 50 |
|
read. It's only used there and read will never be called more than |
| 51 |
|
once. Plus it introduces a reference cycle that keeps can keep the |
| 52 |
|
session object alive for a long time. |
| 53 |
|
|
| 54 |
|

| 55 |
|
|
| 56 |
|
* Thuban/Model/proj.py (Projection): Removed Set*() methods to make |
| 57 |
|
Projection an immutable item. Fixes RTbug #1825. |
| 58 |
|
(Projection.__init__): Initialize instance variables here. |
| 59 |
|
(ProjFile.Replace): New. Replace the given projection object with |
| 60 |
|
the new projection object. This solves the problem of needing the |
| 61 |
|
mutator Projection.SetProjection() in the ProjFrame class and |
| 62 |
|
allows a projection to change parameters without changing its |
| 63 |
|
location in the file. |
| 64 |
|
|
| 65 |
|
* Thuban/UI/mainwindow.py (MainWindow.SaveSessionAs): Dialog should |
| 66 |
|
be of type wxSAVE and should verify overwriting a file. |
| 67 |
|
|
| 68 |
|
* Thuban/UI/projdialog.py (ProjFrame._OnSave): Use the new |
| 69 |
|
ProjFile.Replace() method instead of the mutator |
| 70 |
|
Projection.SetProjection(). Also requires that we reassign the |
| 71 |
|
client data to the new projection. |
| 72 |
|
|
| 73 |
|
* test/test_proj.py (TestProjection.test): Test GetName() and |
| 74 |
|
GetAllParameters() |
| 75 |
|
(TestProjFile.test): Remove tests for Set*() methods. Add tests |
| 76 |
|
for Replace(). |
| 77 |
|
|
| 78 |
|
2003-04-25 Jonathan Coles <[email protected]> |
| 79 |
|
|
| 80 |
|
* Thuban/Model/save.py (SessionSaver.write_projection): Make sure |
| 81 |
|
to save the name of the projection. |
| 82 |
|
|
| 83 |
|
* test/test_save.py (SaveSessionTest.testLayerProjection): New |
| 84 |
|
test to verify layer projections are saved correctly. |
| 85 |
|
|
| 86 |
|
2003-04-25 Jonathan Coles <[email protected]> |
| 87 |
|
|
| 88 |
|
* Thuban/Model/proj.py (Projection.SetName): Set the name |
| 89 |
|
to "Unknown" if name is None. |
| 90 |
|
(Projection.SetAllParameters): New. Set the projection's |
| 91 |
|
parameter list to the one supplied. |
| 92 |
|
(Projection.SetProjection): New. Set the projection's |
| 93 |
|
properties to those of the supplied Projection. |
| 94 |
|
|
| 95 |
|
* Thuban/UI/mainwindow.py (MainWindow.MapProjection): Set |
| 96 |
|
the dialog title to include the map's title. |
| 97 |
|
(MainWindow.LayerProjection): Set the dialog title to include |
| 98 |
|
the layer's title. |
| 99 |
|
|
| 100 |
|
* Thuban/UI/projdialog.py (ProjFrame.__ShowError): Consolidate |
| 101 |
|
error dialogs into a single method call. |
| 102 |
|
(ProjFrame.__VerifyButtons): Add more states to check. |
| 103 |
|
(ProjFrame.__GetProjection): Return the current state of an |
| 104 |
|
edited projection or None. |
| 105 |
|
(ProjFrame.__FillAvailList): Remove checks for states that |
| 106 |
|
shouldn't exist. |
| 107 |
|
(ProjFrame._OnNew): Clear all selected items and supply |
| 108 |
|
a projection panel if necessary. |
| 109 |
|
|
| 110 |
|
* test/test_proj.py (TestProjFile.test): Add tests for |
| 111 |
|
ProjFile.SetAllParameters, ProjFile.SetProjection, |
| 112 |
|
ProjFile.SetName. |
| 113 |
|
|
| 114 |
|
2003-04-25 Jonathan Coles <[email protected]> |
| 115 |
|
|
| 116 |
|
* Thuban/UI/projdialog.py (ProjFrame.__FillAvailList): Now |
| 117 |
|
takes an optional argument to select the current projection. |
| 118 |
|
This does not guarantee that the item is visible due to |
| 119 |
|
limited wxWindows functionality. Fixes RTBug #1821. |
| 120 |
|
|
| 121 |
|
2003-04-25 Jonathan Coles <[email protected]> |
| 122 |
|
|
| 123 |
|
* Thuban/Model/load.py (SessionLoader.start_projection): Remember |
| 124 |
|
the projection name and use it when constructing the Projection |
| 125 |
|
object. |
| 126 |
|
|
| 127 |
|
* Thuban/Model/proj.py (Projection.__init__): Change the default |
| 128 |
|
value for 'name' to None and then test if name is equal to None |
| 129 |
|
in the body of the constructor. This way the caller doesn't have to |
| 130 |
|
know what the default value should be. Namely, useful in load.py |
| 131 |
|
where we have to pick a default value if the 'name' parameter |
| 132 |
|
doesn't exist in the XML file. |
| 133 |
|
|
| 134 |
|
* test/test_load.py (LoadSessionTest.testLayerProjection): New. |
| 135 |
|
Tests a file where a layer has a projection. |
| 136 |
|
|
| 137 |
|
2003-04-25 Jonathan Coles <[email protected]> |
| 138 |
|
|
| 139 |
|

| 140 |
|
tree for projection information. |
| 141 |
|
|
| 142 |
|
* Thuban/Model/load.py (XMLReader.GetFilename): Renamed from |
| 143 |
|
XMLReader.GetFileName. |
| 144 |
|
(SessionLoader): Added support for loading projection tags that |
| 145 |
|
appear inside a layer. |
| 146 |
|
|
| 147 |
|
* Thuban/Model/proj.py (ProjFile): Document the class. Move |
| 148 |
|
back to using a list because the order of the projections in |
| 149 |
|
the file is important to maintain. Fixes RTbug #1817. |
| 150 |
|
|
| 151 |
|
* Thuban/Model/resource.py: Rename calls to ProjFile.GetFileName |
| 152 |
|
to ProjFile.GetFilename. |
| 153 |
|
|
| 154 |
|
* Thuban/Model/save.py (SessionSaver.write_layer): Save projection |
| 155 |
|
information. |
| 156 |
|
|
| 157 |
|
* Thuban/UI/projdialog.py (ProjFrame._OnAddToList): Renamed from |
| 158 |
|
ProjFrame._OnSaveAs. Removed old dead code from previous |
| 159 |
|
implementation. |
| 160 |
|
(ProjFrame._OnExport): Add support for exporting more than one |
| 161 |
|
projection to a single file. |
| 162 |
|
(ProjFrame.__FillAvailList): use string formatting (% operator) |
| 163 |
|
to build strings that are (partly) translated. Fixes RTbug #1818. |
| 164 |
|
|
| 165 |
|
* test/test_proj.py (TestProjFile.test): New. Tests the base ProjFile |
| 166 |
|
class. |
| 167 |
|
|
| 168 |
|
2003-04-24 Bernhard Herzog <[email protected]> |
| 169 |
|
|
| 170 |
|
* po/es.po: Updated Spanish translation by Daniel Calvelo Aros |
| 171 |
|
|
| 172 |
|
* po/fr.po: New. French translation by Daniel Calvelo Aros |
| 173 |
|
|
| 174 |
|
* Thuban/UI/projdialog.py (ProjFrame._OnSaveAs): Don't translate |
| 175 |
|
empty strings. |
| 176 |
|
|
| 177 |
|
2003-04-24 Jonathan Coles <[email protected]> |
| 178 |
|
|
| 179 |
|
* Thuban/Model/layer.py (Layer.GetProjection): New. Needed to |
| 180 |
|
implement the interface that the ProjFrame dialog expects. |
| 181 |
|
|
| 182 |
|
* Thuban/Model/proj.py (Projection.SetName): New. Allows the |
| 183 |
|
name of the projection to be changed. |
| 184 |
|
(ProjFile): Use a dictionary instead of a list so that removing |
| 185 |
|
projections is easier and we are sure about uniqueness. |
| 186 |
|
(ProjFile.Remove): Remove the given projection object. |
| 187 |
|
|
| 188 |
|
* Thuban/Model/resource.py (GetSystemProjFiles, GetUserProjFiles): |
| 189 |
|
Return a list with only one projection file instead of searching for |
| 190 |
|
any projection file. This simplifies many things if the user can |
| 191 |
|
only have one system file and one user file. |
| 192 |
|
|
| 193 |
|
* Thuban/UI/classgen.py: Change all references to |
| 194 |
|
genCombo to genChoice. |

for a layer. |
| 200 |
|
|
| 201 |
|
* Thuban/UI/projdialog.py: Large changes to how the dialog is |
| 202 |
|
laid out. Use three panels instead of one. One for the list of |
| 203 |
|
projections, one for the edit controls, and one for the buttons. |
| 204 |
|
Fixed resizing problems so that the dialog resizes correctly |
| 205 |
|
when the projection panel changes. Added import/export, save, and |
| 206 |
|
new buttons/functionality. |
| 207 |
|
|
| 208 |
|
2003-04-24 Bernhard Herzog <[email protected]> |
| 209 |
|
|
| 210 |
|
First step towards table management. Introduce a simple data |
| 211 |
|
abstraction so that we replace the data a layer uses more easily |
| 212 |
|
in the next step. |
| 213 |
|
|
| 214 |
|
* Thuban/Model/data.py: New file with a simple data abstraction |
| 215 |
|
that bundles shapefile and dbffile into one object. |

|
|
| 217 |
|
* Thuban/Model/session.py (Session.OpenShapefile): New method to |
| 218 |

|
|
| 220 |
|
* Thuban/Model/layer.py (Layer.__init__): Pass the data as a store |
| 221 |
|
object instead of a shapefile filename. This introduces a new |
| 222 |
|
instance variable store holding the datastore. For intermediate |
| 223 |
|
backwards compatibility keep the old instance variables. |
| 224 |
|
(open_shapefile): Removed. No longer needed with the shape store. |
| 225 |
|

| 228 |
|
table anymore. |

| 235 |
|
session's OpenShapefile method to open shapefiles |
| 236 |

|
* test/test_classification.py |
| 238 |
|
(TestClassification.test_classification): Use the session's |
| 239 |
|
OpenShapefile method to open shapefiles and build the filename in |
| 240 |
|
a more platform independed way |
| 241 |
|
|
| 242 |
|
* test/test_layer.py (TestLayer.setUp, TestLayer.tearDown): |
| 243 |
|
Implement to have a session to use in the tests |
| 244 |
|
(TestLayer.test_arc_layer, TestLayer.test_polygon_layer) |
| 245 |
|
(TestLayer.test_point_layer, TestLayer.test_empty_layer): Use the |
| 246 |
|
session's OpenShapefile method to open shapefiles |

| 248 |
|
it to open shapefiles. |
| 249 |
|
(TestLayerLegend.tearDown): Make sure that all references to |
| 250 |
|
layers and session are removed otherwise we may get a resource |
| 251 |
|
leak |
| 252 |
|
|
| 253 |
|
* test/test_map.py (TestMapAddLayer.test_add_layer) |
| 254 |

| 257 |
|
layers, maps and sessions are removed otherwise we may get a |
| 258 |
|
resource leak |

|
("__main__"): use support.run_tests() so that more info about |
| 260 |
|
uncollected garbage is printed |
| 261 |

|
all references to the session and the selection are removed |
| 269 |
|
otherwise we may get a resource leak |

(TestSelection.get_layer): Instantiate a session so that we can |
| 271 |
|
use it to open shapefiles. |
| 272 |

| 276 |
|
(TestSessionWithContent.tearDown): Make sure that all references |

|
on to the next one. |
| 295 |
|
|
| 296 |
|
* test/test_proj.py: Added test cases to handle nonexistent files, |

2003-04-23 Jonathan Coles <[email protected]> |
| 312 |
|
|
| 313 |
|
* Thuban/Model/load.py (XMLReader): Renamed from XMLProcessor to |
| 314 |

| 325 |
|
(XMLReader.endElementNS): Updated to use new dispatcher dictionary. |
| 326 |
|
(SessionLoader): Removed class variables start_dispatcher and |
| 327 |
|
end_dispatcher since this functionality is now part of a class |
| 328 |
|
instance. Fixes RTbug #1808. |
| 329 |
|
(SessionLoader.__init__): Add dispatcher functions. |
| 330 |

|
* Thuban/Model/save.py (XMLWriter): Renamed from XMLSaver to |
| 350 |
|
promote symmetry. |
| 351 |
|
|
| 352 |
|
* Thuban/UI/classgen.py (ClassGenDialog.__init__): Use a wxChoice |
| 353 |
|
control instead of a wxComboBox. wxChoice controls do not generate |
| 354 |
|
events as the uses highlights possible choices which fixes problems |
| 355 |
|
with resizing the dialog when the use selects an option. |
| 356 |
|
|
| 357 |
|
* Thuban/UI/classifier.py (Classifier.__init__): Use a wxChoice |
| 358 |
|
control instead of a wxComboBox. |
| 359 |
|
|
| 360 |
|
* Thuban/UI/mainwindow.py (MainWindow.Projection): Use new projection |
| 361 |
|
dialog. |
| 362 |
|
|
| 363 |
|
* test/test_proj.py (TestProjection.test): New tests for GetParameter |
| 364 |
|
method. |

|
* Thuban/UI/mainwindow.py: Remove some unused imports and global |
| 369 |
|
constants |
| 370 |
|
|
| 371 |
|
* Thuban/UI/identifyview.py (IdentifyListCtrl.selected_shape) |
| 372 |
|
(IdentifyGridCtrl.selected_shape): Use table, not shapetable. |

|
|
| 376 |
|
* Thuban/Model/layer.py: Don't import LAYER_LEGEND_CHANGED. |
| 377 |
|
(Layer): Update doc-string since LAYER_LEGEND_CHANGED is not used |
| 378 |
|
anymore. |
| 379 |
|
(Layer.BoundingBox, Layer.GetFieldType, Layer.NumShapes) |
| 380 |
|
(Layer.ShapeType, Layer.Shape): No need to call |
| 381 |
|
self.open_shapefile since it's always called in __init__ |
| 382 |
|
|
| 383 |
|
* Thuban/UI/application.py (ThubanApplication.MainLoop): Removed. |
| 384 |
|
In wxPython 2.4 there's no need to extend MainLoop anymore since |
| 385 |
|
wxPython itself makes sure OnExit is called. |

|
Initial putback of projection management code. Includes new |
| 390 |
|
classes to read and write projection files. The current load |
| 391 |
|
and save classes were abstracted a bit so they could be reused. |
| 392 |
|
The Projection class was extended to provide new methods and |
| 393 |
|
have a name. |
| 394 |
|
|
| 395 |
|
* Thuban/Model/load.py (XMLProcessor): New. Contains all the |
| 396 |
|
general XML reading methods that were part of ProcessSession. |
| 397 |
|
|
| 398 |
|
* Thuban/Model/proj.py (Projection.__init__): Accepts an optional |
| 399 |
|
name. |
| 400 |
|
(ProjFile): New. Represents a file that contains projection |
| 401 |
|
information. |
| 402 |
|
|
| 403 |
|
* Thuban/Model/resource.py: New. Contains general utilities |
| 404 |
|
for read and writing projection files. |
| 405 |
|
|
| 406 |
|
* Thuban/Model/save.py (XMLSaver): New. Contains all the |
| 407 |
|
general XML writing methods that were part of SessionSaver. |
| 408 |
|
(SessionSaver): Renamed from Saver. |
| 409 |
|
|
| 410 |
|
* test/test_proj.py: New test cases for the projection |
| 411 |
|
file read and write functions. |
| 412 |
|

| 414 |
|
|
| 415 |
|
* Thuban/Model/classification.py: Use repr() around values |
| 416 |
|
in the ClassGroup*.__repr__() methods so it is clearer when |
| 417 |
|
a value is a string and when it is a number. |
| 418 |
|
|
| 419 |
|
* test/test_load.py: Rework the classification test to test |
| 420 |
|
that we can load old files. |
| 421 |
|
(testLabels): Test a file where the groups have labels. |
| 422 |
|
|
| 423 |

|
Safer implementation of the performance enhancements of the |
| 426 |
|
low-level renderer: |
| 427 |
|
|
| 428 |
|
* extensions/thuban/wxproj.cpp (extract_projection) |
| 429 |
|
(extract_pointer): Rename extract_projection to extract_pointer |
| 430 |
|
and redefine its purpose to return the pointer stored in a CObject |
| 431 |
|
returned by the object's cobject method. Update all callers. |
| 432 |
|
(s_draw_info, free_draw_info, draw_polygon_init): Implement the |
| 433 |
|
handling of these low-level parameters so that each s_draw_info |
| 434 |
|
instance is handled as a CObject at python level that also |
| 435 |
|
contains real references to the actual python objects which |
| 436 |
|
contain the values in the struct. Add free_draw_info as the |
| 437 |
|
destructor. |
| 438 |
|
(draw_polygon_shape): Add the py_draw_info parameter which must a |
| 439 |
|
cobject containing an s_draw_info pointer. |
| 440 |
|
|
| 441 |
|
* Thuban/UI/renderer.py (MapRenderer.polygon_render_param): New |
| 442 |
|
method to instantiat the low-level render parameter |
| 443 |
|
(MapRenderer.draw_shape_layer): Use the new method. Remove some |
| 444 |
|
commented out code. |
| 445 |
|
(MapRenderer.draw_polygon_shape): Make the first parameter not the |
| 446 |
|
layer but the low-level render parameter |
| 447 |
|
(ScreenRenderer.draw_shape_layer): Use the low-level render |
| 448 |
|
parameter. |

| 451 |
|
|
| 452 |
|
* Thuban/Model/classification.py: Implemented __repr__ for |
| 453 |
|
the ClassGroup* classes to make debugging a bit easier. |
| 454 |
|
(ClassGroup.SetLabel): Check that the string is an instance |
| 455 |
|
of StringTypes not StringType. Accounts for Unicode strings. |
| 456 |
|
|
| 457 |
|
* Thuban/Model/color.py: Implemented __repr__ to make |
| 458 |
|
debugging a bit easier. |
| 459 |
|
|
| 460 |
|
* Thuban/Model/save.py (Saver.write_classification): Need to |
| 461 |
|
save the group label. |
| 462 |
|
|
| 463 |
|
* test/test_load.py (testClassification): New. Loads the |
| 464 |
|
iceland_sample_test.thuban file and checks if it was loaded |
| 465 |
|
correctly. |
| 466 |
