[Qgis-developer] Changes to vector layers persist between python integration tests.
Hi,
I am having trouble with integration tests that I am writing in a Python
plugin. The tests run correctly one at a time, but when I run them together
only the first test works correctly. It seems that changes it makes to the
database are still present in the later tests. How can I make sure that the
vector layer / database is fully reset between tests?
My tests are based on unittest.TestCase. The QGIS app is started with
QGISAPP.initQGIS() as in the main QGIS tests and a Mock iface is used.
In the setUp, I make a temporary copy of a template spatialite file and run an
SQL script on it to add features and other data. I connect to the database and
store a reference to it (self.db). Then I load one of the tables as a
QgsVectorLayer and store a reference to it (self.esu).
The first test uses self.esu.dataProvider().deleteFeatures() to remove
features, the second uses self.esu.dataProvider().addFeatures() to add
features. They check that the features have been added and that other database
changes have been made.
The teardown contains the following:
if self.db: # Just in case self.db doesn't get set
self.db.close()
del self.db
QSqlDatabase.removeDatabase('integration_testing')
self.esu = None
reg = QgsMapLayerRegistry.instance()
reg.removeAllMapLayers()
reg.clearAllLayerCaches()
if os.path.exists(self.test_db_path):
os.remove(self.test_db_path)
I thought that this would be enough to reset any references to the vector
layer, but if I delete a feature in the first test, it is still gone when I run
the second test. Is QGIS holding any other references to the layers that I
have missed?
Cheers
John

Re: [Qgis-developer] Problem definig snapping options programmatically
Hi all, This is the same issue that I had a few months ago [1]. (Thanks Tom for flagging it up). You can recreate in the console as follows as follows (QGIS 2.14.3, with one vector layer loaded): ``` vlayer = QgsMapLayerRegistry.instance().mapLayers().values()[0] proj = QgsProject.instance() proj.setSnapSettingsForLayer(vlayer.id(), True, QgsSnapper.SnapToVertex, QgsTolerance.LayerUnits, 5.0, False) ``` The settings are not applied. "Settings > Snapping Options > Snapping Mode" remains at "Current Layer". Changing this to to "Advanced" shows correct values have been set, but they are not activated until "Apply" is pressed. Connecting a function to QgsProject.instance().snapSettingsChanged() shows that the signal fires with no arguments when setSnapSettingsForLayer is called. Emitting the signal manually does nothing.

Re: [Qgis-developer] QGIS crashes when doing a rollback after modifying values of an user-added feature with pyQGIS
Hi Manuel,
I struggled with a similar problem. Another possible workaround is waiting
until the user has saved their edits. You can then catch the
commitedFeaturesAdded signal and update the layer directly using the provider.
This method has the advantage that the fid that refers to the feature at this
stage is the final one and does not change.
See this Stack Overflow page for more info:

Unfortunately this is currently a limitation of our current editing
system... When an editing signal (like "featureAdded") is emitted,
doing some extra editing actions will corrupt the undo stack because
the undo command of the previous action is not yet finished. A
possible workaround could be to use queued signal/slot connection
instead of direct connection (which is the default), so the slot
execution will be delayed, and the undo stack will get to a consistent
state.
Regards
Martin

Re: [Qgis-developer] Setting snapping settings via Python
Thanks for help so far. These suggestions seem to be more complicated than I require. I do not need to use the snapper to modify geometries in a custom tool, just to turn snapping on for the current layer when the user begins editing it. I tried the following, based on Etienne's inasafe example, but nothing happens: layer = canvas.layer(0) point_locator = QgsPointLocator(layer) units = QgsTolerance.LayerUnits layer_config = QgsSnappingUtils.LayerConfig(layer, point_locator.Types(), 50, units) snapper = QgsSnappingUtils() snapper.setLayers([layer_config]) snapper.setSnapToMapMode(QgsSnappingUtils.SnapAdvanced) Is there another snapper already created by QGIS when editing begins that I can access?

Re: [Qgis-developer] Setting snapping settings via Python
I have now managed to change the settings for an individual layer, via the QgsProject class. But this method only works if the snapping mode is set to 'Advanced' in the GUI dialog (Settings > Snapping Options). proj = QgsProject.instance() proj.setSnapSettingsForLayer(layer.id(), True, QgsSnapper.SnapToVertexAndSegment, QgsTolerance.LayerUnits, 5.0, False) Is there a way to set this snapping mode via Python?

[Qgis-developer] Setting snapping settings via Python
Hi,
Is there a way to set the snapping settings for a layer via Python? I would
like to turn on snapping with a specified tolerance automatically when a user
begins editing within a plugin.
There is a question on gis.stackexchange, but it hasn't been answered.
http://gis.stackexchange.com/questions/133816/how-to-enable-the-snapping-options-for-vector-layer-using-the-python-programming
QSettings stores some values, but these are the defaults:
qs = QSettings()
qs.value('Qgis/digitizing/default_snap_mode')
qs.value('Qgis/digitizing/default_snapping_tolerance')
qs.value('Qgis/digitizing/default_snapping_tolerance_units')
I have also found the canvas.snappingUtils(), but cannot find functions there
to enable snapping modes or set tolerances.
Thanks,
John

[Qgis-developer] Disable undo feature for user geometry edits within plugin / general undoStack() questions
Hi,
I am writing a plugin that modifies a spatialite database in response to
geometry edits made by the user. The attribute table for the modified feature
is modified when an item is added or edited, and additional tables within the
database are updated with the new information. The undo button does not revert
the database changes (and can cause crashed in Linux), so I would like to
prevent the user being able to use it.
So far, I have worked out how to disable the undo button (and shortcut) by
disabling the corresponding action. But when I connect that to a signal, it
fires but the undo is still enabled, but with a different corresponding action.
So far I have a class that initiates on beginEditing whose contents include the
following:
```
def __init__(self, iface, layer, db):
. various lines here
self.undo_stack = layer.undoStack()
def connect_signals(self):
various lines here
self.undo_stack.indexChanged.connect(self.disable_undo_button)
self.undo_stack.canUndoChanged.connect(self.disable_undo_button)
self.undo_stack.cleanChanged.connect(self.disable_undo_button)
self.undo_stack.undoTextChanged.connect(self.disable_undo_button)
def disable_undo_button(self):
"""
Disable GUI undo buttons to prevent user trying to undo edits, which
is prone to causing crashes.
"""
print('Disabling undo button')
actions_to_disable = ['', '']
for action in self.iface.editMenu().actions():
menu_item_action_text = action.text()
if menu_item_action_text in actions_to_disable:
action.setDisabled(True)
print(id(action))
```
The disable_undo_button() function works, so it seems that another action is
being added as the current undo without any of the signals that I am listening
for being called.
- When is the final change made to the undoStack?
- Is there a signal that I can listen for to disable undo afterwards?
- or is there generally a better way to disable undo functionality?
Cheers
John

[Qgis-developer] Undo command crashes QGIS when called from within plugin.
Hi,
I have code within a plugin that I am writing that is similar to:
```
def feature_added(self, fid):
self.vlayer.beginEditCommand('Update attributes')
self.vlayer.changeAttributeValue(fid, 2, 17)
self.vlayer.endEditCommand()
```
It is called in response to a featureAdded signal from the layer. The command
runs and the attributes are updated and the canvas refreshes to show them.
However, when I check the undoStack for the layer, the command is not present.
When I press 'Undo', QGIS has a hard crash.
If I use the QGIS iPython console to access the layer directly through my
plugin (e.g. via qgis.utils.plugins['MyPlugin']) and type the equivalent
commands directly into the console, everything works as expected, but the
changes are not visible until the canvas is manually refreshed.
Is there something else that should / shouldn't be called by the plugin to put
the undo command onto the stack?
I'm on QGIS 2.12.0 on Linux Mint 17 (Ubuntu 14.04).
Thanks,
John

Hi, When QGIS starts, it calls the __init__.py and the __init__ method of my plugin, but not the initGui method. Once QGIS has started, the plugin appears in qgis.utils.available_plugins but not in qgis.utils.active_plugins. If I call qgis.utils.startPlugin, then __init__.py, Plugin.__init__ and Plugin.initGui are all called and the plugin becomes active. When is initGui / startPlugin called method during QGIS loading? Is there something that my initGui should contain (or that my __init__ should not contain) so that the initGui gets called on QGIS startup? I’m using QGIS 2.12.0 on Mint 17 Mate (ubuntu 14.04).

Re: [Qgis-developer] Plugin: initGui not called on QGIS startup?
Hi Tom, It is one that I am writing myself. I've looked at others e.g. openlayers, plugin reloader and they all have their initGui methods called, so I am trying to understand why mine is not.

Re: [Qgis-developer] Plugin: initGui not called on QGIS startup?
Hi Matthias, A very good question. No, I had not. I had just copied the module directory into my plugins directory. Now that it is activated, the initGui and unload methods are begin called on QGIS start up and close down. Thank you!

Hi John, Sorry for a probably a stupid question, but did you activate the plugin in the plugin manager?

[Qgis-developer] Spatialite database locked after layer removal.
Hi, I am having trouble renaming a spatialite database that I have been using in QGIS (2.10.1-Pisa). I have been working in Python, but the problem can be easily recreated through the GUI. 1) Add spatialite layer from sqlite file 2) Remove spatialite layer (right click, remove) 3) Rename or delete the sqlite file Python gives ‘WindowsError’ in Windows 7, or ‘OSError’ in Xubuntu 14.04. The Linux terminal gets: mv: cannot move ‘test.sqlite’ to ‘test2.sqlite’: Text file busy After a few (1-5?) minutes the lock is removed. With shape file layers, the lock is removed as soon as the layer is removed. Is there a reason for the delay with the spatialite file? Is there a command that I can call to refresh/drop the connection more quickly?
