Re: [QGIS-Developer] Failure in uploading plugin

[Mauro Alberti]

Changing PC, always Linux Mint (more recent version) and same zip creation
procedure, the upload worked.
Possibly a zip format incompatibility.

Thanks,
mauro

zipping the folder name 'qProf' in Linux. Are there any particular
assumption/requirement about the uploaded zip structure?

[QGIS-Developer] Failure in uploading plugin

[Mauro Alberti]

Hi,
I am receiving errors when I try to upload a new version of qProf plugin.
I've checked the metadata, but after trying the upload I always get the
message:

*There were errors reading plugin package (please check also your plugin's
metadata). Could not unzip file.*
and I am not sure where the problem could be. I have tested the manual
installation from unzipping the file and there were no problems
Are there alternative ways to submit a new plugin version?

thanks,
mauro

[Qgis-developer] QGIS Win64 minidump due to GDAL function

[Mauro Alberti]

Hi all,
I have a persistent issue with a Python plugin of mine, qgSurf.
There is no (observed) problem when using this plugin in Linux (Mint) 64
bit with QGIS 2.4 or 2.6, or for QGIS 2.4 in Win 32 bit (I don't know for
QGIS 2.6 Win32).
However, when using it in a Win64 versions, be it 2.4 or 2.6 from
standalone installers, at the QGIS closing a minidump is always created.
I've tracked the single offending command: it's the use of the GDAL
function ReadAsArray, for reading the content of a raster band.

I don't know if this is a known issue of GDAL in QGIS Win64, and if it
could be solved in one of the next releases of QGIS 64 bit for Windows.

Thanks,
Mauro

Hi,
I've uploaded an example as a zipped file:

There were no messages in the Python console.

[Qgis-developer] Metasearch error in Qgis 2.3.0-21 64bit Win

[Mauro Alberti]

Hi all,
I'm trying QGIS from standalone installer 2.3.0-21 64bit (Win 8) and at the
start I'm getting  a message error related to the MetaSearch plugin, that
doesn't find the pytz module.
Is this a known issue?

No, at least in my case the MetaSearch module bundled with the installer
doesn't start correctly and is then signalled as corrupted, due to lack of
 the pytz dependency. I've tried unistalling and then reinstalling QGis
2.3, same situation.
The other pre-installed Python plugins in apps\qgis-dev\python\plugins
(fTools, etc.) seem to have no problem.

[Qgis-developer] Errors with destinationCrsChanged and hasCrsTransformEnabledChanged signals

[Mauro Alberti]

Hi everyone,
i'm not able to connect to *destinationCrsChanged *and
*hasCrsTransformEnabledChanged
*signals from  a map canvas, in a Python plugin.

My code sample is:
*self.canvas.destinationCrsChanged.connect( self.get_current_canvas_crs )*
*self.canvas.hasCrsTransformEnabledChanged[bool].connect(
self.get_on_the_fly_projection )*
and an instance of error message, when loading the plugin, is:
*AttributeError: 'QgsMapCanvas' object has no attribute
'destinationCrsChanged'*

I've tried successfully, just to test, with two other signals for a
QgsMapCanvas instance:

*self.canvas.zoomLastStatusChanged[bool].connect(
self.get_current_canvas_crs )*
*self.canvas.layersChanged.connect( self.get_current_canvas_crs )*

Perhaps the two signals with errors are not implemented in PyQGis? And in
that case, are there any workaround?

thanks,
mauro

Re: [Qgis-developer] Fwd: A pipinstall plugin is possible? First: What's the difference between the the Osgeo4w Shell?

[Mauro Alberti]

In my opinion, a much simpler and cleaner approach (at least from the point
of view of a normal user), would be to allow, in QGis Windows (standalone
installer), the user not to point to (or not install) an internal Python,
but to refer to an external installation. For instance, to point to a
Python installed via Python(x,y), where there is already a plenty of
modules installed and it is very easy to install/update via
pip/easy_install and so on.

But I'm not sure if some Python modules are customized to be compatible
with QGIS Windows interface: for instance, some months ago, I tried
unsuccessfully to update, via copy-and-paste from the Python(xy) site
packages, numpy to a more recent version than the one available in Qgis
(don't remember if 1.8 or 2.0).

 I don't know what's the ongoing progress on this topic but I think that a
 system for the dependencies management should be embedded inside QGIS. I'm
 not in favour for a plugin to do that.
 Having an integrated pip would be more transparent to the user and the
 plugin developers. The developer should only provide a requirements file
 which should be transparently managed by the QGIS' Python system.
 I heard that Nathan is working on something similar?

 Hi to all,
 I'm trying to realize a little plugin to install python modules on
 windows via pip.

 In first, I would like make a simple thing:
 Run get-pip.py inside the plugin  but I encounter two different problem:

 What is the shell to call? (Please, don't mind If I point at dufour, is
 my qgis crushtest dummy )

 subprocess.call('C:\\PROGRA~2\\QGISDU~1\\Osgeo4W.bat python get-pip.py')

 or

 subprocess.call('C:\Program Files (x86)\QGIS Dufour\OSGeo4W.bat python
 get-pip.py')

 Apparently they are the same, but if I install something through  python
 inside one, I cannot import the module inside the other.

 So, what's the right way to call inside a python plugin the shell?

 I found also some problems in using subprocess on windows, and I'm
 developping using QProcess class.

 Second question:
 If I run
 subprocess.call('C:\Program Files (x86)\QGIS Dufour\OSGeo4W.bat python
 get-pip.py')

 I receive: Nothing distributions at all found fo install...

 So the solution are easy: distribute qgis with pip and easy_install
 inside, or install pip and easy_intall from shell as I did, then we can use
 the plugin as you check out in my screenshots:
 [0]

 So, if you have suggestions plese let me know.

 Best regards
 Luca

[Qgis-developer] plugin requiring guiqwt

[Mauro Alberti]

Hi all,
I've created a tool in Python, that requires guiqwt for the interactive
graphical definition of spline parameters. I would like to include it into
a plugin of mine (for Qgis 1.8), that currently does not require any
non-standard Python module.
I don't know what could be the best way, mainly from the user point-of
view, for managing the absence of this module in QGIS Python.

Thanks for any suggestion,

mauro
