|
Tweak the usage of the sqlite database to make common use cases |
| 4 |
|
more responsive. In most cases copying the data to the sqlite |
| 5 |
|
database takes so long that using sqlite doesn't have enough |
| 6 |
|
advantages. |
| 7 |
|
|
| 8 |
|
* Thuban/Model/transientdb.py (TransientTableBase.ValueRange): Add |
| 9 |
|
comments about performance and query the min and max in separate |
| 10 |
|
statements because only that way will indexes be used. |
| 11 |
|
(TransientTableBase.UniqueValues): Add some comments about |
| 12 |
|
performance. |
| 13 |
|
(AutoTransientTable.ValueRange, AutoTransientTable.UniqueValues): |
| 14 |
|
Do not copy the data to the transient DB but use the transient |
| 15 |
|
copy if it exists. See the new comments for the performance trade |
| 16 |
|
offs |
| 17 |
|
|
| 18 |
|
* test/test_transientdb.py |
| 19 |
|
(TestTransientTable.test_auto_transient_table): Make sure that the |
| 20 |
|
data is copied to the transient database at some point. |

|
| 24 |
|
* Thuban/Model/data.py (ShapefileStore.ShapesInRegion): Bind some |
| 25 |
|
globals to locals so that it's a bit faster |
| 26 |
|
|
| 27 |
|

| 28 |
|
|
| 29 |
|
* Thuban/UI/baserenderer.py |
| 30 |
|
(BaseRenderer.draw_shape_layer_incrementally): Use the ReadValue |
| 31 |
|
method. ReadValue is faster than ReadRowAsDict since it only reads |
| 32 |
|
one cell especially now that the dbf file objects actually |
| 33 |
|
implement it. |
| 34 |
|
|
| 35 |
|
* Thuban/Model/table.py (DBFTable.ReadValue): Use the new |
| 36 |
|
read_attribute method of the dbf objects |
| 37 |
|
|
| 38 |
|

|
* Extensions/profiling/profiling.py (popup_dialog_box): New config |
| 41 |
|
variable to indicate whether the result should be shown in a |
| 42 |
|
dialog box |
| 43 |
|
(profile_screen_renderer, time_screen_renderer): Only show a |
| 44 |
|
dialog box if popup_dialog_box is true. |
| 45 |
|
(profile_screen_renderer): Flush stdout after the printing the |
| 46 |
|
first part of the "profiling..." message |
| 47 |
|
|
| 48 |
|
* Thuban/UI/baserenderer.py |
| 49 |
|
(BaseRenderer.draw_shape_layer_incrementally): Cache the pens and |
| 50 |
|
brushes for the groups so that they're not created over and over |
| 51 |
|
again |
| 52 |
|
|
| 53 |
|
* Thuban/Model/classification.py (Classification.__getattr__) |
| 54 |
|
(Classification._compile_classification) |
| 55 |
|
(Classification._clear_compiled_classification): New. Methods to |
| 56 |
|
manage a 'compiled' representation of the classification groups |
| 57 |
|
which is created on demand |
| 58 |
|
(Classification.InsertGroup, Classification.RemoveGroup) |
| 59 |
|
(Classification.ReplaceGroup): reset the compiled representation |
| 60 |
|
(Classification.FindGroup): Use the compiled representation to |
| 61 |
|
find the matching group |
| 62 |
|
(ClassGroupRange.GetRangeTuple): New. Return the range as a tuple |
| 63 |
|
|

* Thuban/Model/classification.py (Classification.SetDefaultGroup): |
| 67 |
|
Send a CLASS_CHANGED message |
| 68 |
|
(Classification.RemoveGroup): Send a CLASS_CHANGED message and do |
| 69 |
|
not return the removed group since it wasn't used. |
| 70 |
|
|
| 71 |
|
* test/test_classification.py |
| 72 |
|
(TestClassification.test_set_default_group): New. Test the |
| 73 |
|
SetDefaultGroup method |
| 74 |
|
(TestClassification.test_insert_group): New. Test the InsertGroup |
| 75 |
|
method |
| 76 |
|
(TestClassification.test_remove_group): New. Test the RemoveGroup |
| 77 |
|
method |
| 78 |
|
(TestClassification.test_replace_group): New. Test the |
| 79 |
|
ReplaceGroup method |

| 85 |
|
(TestClassification.tearDown): New. Destroy the classification |
| 86 |
|
properly |
| 87 |

|
