* Thuban/UI/mainwindow.py (MainWindow.SetMap): Look up the |
| 4 |
|
legend dialog box and tell it to change its map to the one |
| 5 |
|
supplied to SetMap(). Fixes RTbug #1770. |

|
Next step of table implementation. Introduce a transient database |
| 10 |
|
using SQLite that some of the data is copied to on demand. This |
| 11 |
|
allows us to do joins and other operations that require an index |
| 12 |
|
for good performance with reasonable efficiency. Thuban now needs |
| 13 |
|
SQLite 2.8.0 and pysqlite 0.4.1. Older versions may work but I |
| 14 |
|
haven't tested that. |
| 15 |
|
|
| 16 |
|
* Thuban/Model/transientdb.py: New. Transient database |
| 17 |
|
implementation. |
| 18 |
|
|
| 19 |
|
* test/test_transientdb.py: New. Tests for the transient DB |
| 20 |
|
classes. |
| 21 |
|
|
| 22 |
|
* Thuban/Model/session.py (AutoRemoveFile, AutoRemoveDir): New |
| 23 |
|
classes to help automatically remove temporary files and |
| 24 |
|
directories. |
| 25 |
|
(Session.__init__): New instance variables temp_dir for the |
| 26 |
|
temporary directory and transient_db for the SQLite database |
| 27 |
|
(Session.temp_directory): New. Create a temporary directory if not |
| 28 |
|
yet done and return its name. Use AutoRemoveDir to have it |
| 29 |
|
automatically deleted |
| 30 |
|
(Session.TransientDB): Instantiate the transient database if not |
| 31 |
|
done yet and return it. |
| 32 |
|
|
| 33 |
|
* Thuban/Model/data.py (ShapefileStore.__init__): Use an |
| 34 |
|
AutoTransientTable so that data is copied to the transient DB on |
| 35 |
|
demand. |
| 36 |
|
(SimpleStore): New class that simply combines a table and a |
| 37 |
|
shapefile |
| 38 |
|
|
| 39 |
|
* Thuban/Model/table.py (Table, DBFTable): Rename Table into |
| 40 |
|
DBFTable and update its doc-string to reflect the fact that this |
| 41 |
|
is only the table interface to a DBF file. Table is now an alias |
| 42 |
|
for DBFTable for temporary backwards compatibility. |
| 43 |
|
|
| 44 |
|
* Thuban/UI/application.py (ThubanApplication.OnExit): Make sure |
| 45 |
|
the last reference to the session goes away so that the temporary |
| 46 |
|
files are removed properly. |
| 47 |
|
|
| 48 |
|
* test/test_load.py (LoadSessionTest.tearDown): Remove the |
| 49 |
|
reference to the session to make sure the temporary files are |
| 50 |
|
removed. |

|
|
| 54 |
|
* Thuban/Model/load.py (XMLReader.__init__, XMLReader.read): Turn |
| 55 |
|
the __parser instance variable into a normal local variable in |
| 56 |
|
read. It's only used there and read will never be called more than |
| 57 |
|
once. Plus it introduces a reference cycle that keeps can keep the |
| 58 |
|
session object alive for a long time. |
