Re: [Qgis-developer] SSL error on QGIS startup

2015-10-01 Thread Andreas Neumann

To add some more information: this is on Ubuntu 15.04 64bit.

I also tried starting QGIS without plugins, because I thought that maybe 
a Python Plugin may want to load something from the web, but the error 
message still appears.


Thanks,
Andreas

[Qgis-developer] Dev/test/bug fixing ratio for next LT release

2015-10-01 Thread Andreas Neumann

Hi Jürgen,

Have you given it some thoughts whether we should have a longer testing 
and bug fixing period before the LT release? E.g. 2.5 months development 
and 1.5 months testing/bug fixing? Or 2 months dev and 2 months 
testing/bug fixing?


Would be good to know early on, esp. for the devs and organizations 
hiring devs.

Note that with such feature, there would only need to be a single
new interface in the C-API, namely requesting reduction of the
precision of a geometry and optional scaling of coordinates.
There would be no need at all to expose PrecisionModel or
GeometryFactory to the outside world. Internally, the C-API might
still try to optimize the memory by re-using existing factories
with the same PrecisionModel.

I guess this discussion would be better conducted on geos-dev

I've stubbed this mechanism here:
https://github.com/libgeos/libgeos/pull/52

Basically, once you don't need an explicit handle on your
GeometryFactory you can call its "autoDestroy()" method and
it will be destroyed once all the geometries referencing it
are also deleted.

Could be a key to what we're trying to do here.

There is no need to have GISBASE variable set (path to directory where
GRASS binaries live) when GRASS GIS is started explicitly as a 'grass'
command later on. If you have GISBASE, grass command will end with error as
GISBASE says that you are already in GRASS session.

Why GISBASE is set, or if deleting it is just a precaution, I have no idea.

new one so you can try to remove the lines from 48 to 51 of
openlayers_layer.py file and replace the row 52:
self.setNetworkAccessManager(self.__manager)
with the following:
self.setNetworkAccessManager(QgsNetworkAccessManager.instance())
I just try and it goes but I don't know if it resolvs your issue.

Operation never pre-reduce inputs.
That's why I added the second parameter.
The only reason to pass "false" would be an optimization in case you
know in advance your geometry is already constrained to the grid
registered in the factory (that'd be case 1 in my mail from
https://lists.osgeo.org/pipermail/geos-devel/2015-January/007097.html)

The only way to construct geometries with the GEOS C-API
right now is via WKB or WKT or passing a CoordinateSequence to any
GEOSGeom_create* function. None of them applies any rounding and
attached a singleton-like GeometryFactory to the result. So right
now all geometries out of the C-API contain a reference to the very
same GeometryFactory.

Exposing function like:

 GEOSIntersection_reducedPrecision

Would pose the question of whether or not the coordinates of input
should be reduced. If we do reduce them, then chained operations
would keep rounding the same coordinates again and again, while
by storing the precision info inside each Geometry we are defining
what is already rounded and to which grid.

As known from the beginning, the challenge here is dealing with
management of the many GeometryFactory objects that would result
from the possibility of expressing them freely, and I start thinking
there's no way out of this than adding refcounting to the
GeometryFactory object so that it self-manages.

I'll be trying something to that extent for the time being.

As for QGIS, I guess you could have a function to "reduce" and a
function to "register" a factory. So chained operations would:

 0. reduce
 1. register reduced factory
 2. perform operation 1
 3. perform operation 2
 4. ...
 5. register original factory

In this case the "reduced factory" would just have a short living, and
at the end of the operation chain there would still be a single
factory alive.

If one sets the reduced precision factories on the geometries, does one

[Qgis-developer] QGis and Socrata

2015-10-01 Thread francesca.cella
Is it possible to access tabular data, without geometry field, (format json)
from Socrata OpenData in QGis, in order to link them to other geodata?
I found python code that does writing data in an existing table, but this is
not a "live" connection.

Cheers
Francesca

We now depend on something that is not even in the latest GEOS and we also
build on platforms/distributions that would be behind even if the latest GEOS
supported this.  So the geosextra stuff and the geos C++ dependency will have
to stay for those.  In OSGeo4W I'll just update the patch in the GEOS package -
as we don't ship the C++ API there anyway - to avoid trouble with the compiler
abi zoo on windows.

I've found that qgis is now dependent on the C++ GEOS API,

It seems to me that the "geosextra" code in its current incarnation
only exposes a function to basically round coordinates to a precision
grid, but in no way changes the precision of operations performed by
further GEOS functions on the resulting geometries.

This is discussed in detail in https://trac.osgeo.org/geos/ticket/713

So my question is: if grid-snapping is enough for QGIS use, is adding
a new dependency on GEOS really needed, or isn't there other internal
code for doing coordinates editing work (would seem easy with Qt
standard library?).
As resulted from the discussion in the geos ticket: the goal is having 
the operations run in reduced precision, not just merely snap to grid. 
The discussion revealed however that snap to grid is basically what ends 
up being done with the current implementation, due to a 
mis-understanding of mine of the geos internals. As suggested in the 
geos ticket, I'd like to fix this to work as initially intended, and 
keep geosextra in QGIS until a new release of GEOS comes out which 
implements needed changes in the C-API.


As I've been asked to help with getting the code in place for what
I've understood are good new functionalities I'm here to better
understsand the issue, why the new code is needed and how to best have
it available, considering also that latest GEOS release was published

[Qgis-developer] OpenlayersPlugin QGIS

2015-10-01 Thread Marica Landini
Hi,
I need to use OpenlayersPlugin QGIS behind proxy network.
But I need to use defaultproxy settings configuration.

QGIS works fine with this defaultproxy settings
(also connection to wms/etc...
reading plugin list and download it).

But (with the defaultproxy settings) I can not work with OpenlayersPlugin
QGIS
that return:
TypeError: unable to convert a QVariant of type 10 to a QMetaType of type 2

I can instead use this plugin with http proxy and setting manually the
configuration (Settings->Options->Network)

I have tryed to modify OpenlayersPlugin tool_network.py
commenting setHostName/setPort/setUser/setPassword
and using
QNetworkProxy.setApplicationProxy(QNetworkProxy(QNetworkProxy.DefaultProxy))
obvious I do not get TypeError,
but the plugin not work properly (e.g. I do not get OSM layer).

How can I resolve this problem?
There is another plugin that works with default (machine) proxy settings?
(apologies for my english)...

Cheers,
Marica

I deliberately did not set the milestone version to 2.14 on

https://github.com/qgis/QGIS/pull/2322

but I did not feel comfortable enough myself to merge it (not due to
lack of quality of the PR but due to lack of expertise).
+1 from my side to have this merged IF sombody can step in and give it
an additional review.

In general, I try to filter and roughly review PR's and delegate them
wherever possible. I agree that they need more attention and a stance on
this problem by the PSC is highly appreciated.

Hi,


It would be nice to have the possibility to get back to this page, but
as Kari said, it takes away screen real estate. What do you think about
bringing the page back when somebody clicks "open project" and embed a
file browser window next to the previous projects?

We could also have a menu entry in the "Help" menu or "Project" Menu to 
bring back the start screen?


Or we could have a "Close" project which would bring back the start screen.

I am not sure to understand the problem, i.e. what happens with qgis
server that does not with the regular map canvas ?

But to answer your question, there is already a margin taken around the
map extent :
https://github.com/qgis/QGIS/blob/master/src/core/symbology-ng/qgsinvertedpolygonrenderer.cpp#L95

This is completely arbitrary (x5), but this is just to cheat the concept
of an "inverted" geometry that does not really exist in QGIS. So we can
bump up the factor to say x10 ... and it will just translate the problem
a bit further ...

The solution proposed by Nyall (adding the possibility to have an
infinite distance if I understood correctly) is better I think.

Hello Hugo,

I don't know the details of your PRs but generally speaking I fully agree
with your concerns about paid developments and uncertainty of PRs
acceptance.

Hopefully the new commitments of the PSC about the PRs queue handling will
solve this problem in the long run.

Hi,

I've submitted two Pull Requests :
https://github.com/qgis/QGIS/pull/2189 and
https://github.com/qgis/QGIS/pull/2322 that stay in a undetermined state ...

The first one (2189) is of particular interest here. It has been opened
in the beginning of July and I've been fixing issues spotted by others
(mostly Nyall), unfortunately at a lower pace than I would have liked,
busy on other projects.

But agreement from other devs seemed needed to accept it. And ... this
agreement never came before the beginning of the feature freeze ...
So can you confirm this is now out of the scope of the 2.12 ? Or is
there a chance this would be an exception ?

I guess this happened because everyone is busy, but it is not an easy
situation for me.
It becomes hard to target a particular release version when selling the
integration of new features and then it does not enforce confidence of
funders, I think.

Do you see solutions to that for the future ? Probably the problem is
that integration of paid development depends on decisions made by
third-party developers that do their best to review PRs, but without
guarantee (i.e. are not paid specifically for that). What do you think ?

sweet! Nathan, would you like me to open a feature req, to better
