Re: [QGIS-Developer] how to run qgis from source

[Patrick Dunford]

You need to amend your PATH environment variable to point to the folder 
that has those DLLs in it (leave them in the folder they were originally in)

Re: [QGIS-Developer] What are "Key/value" and "List" widgets in attributes form?

[DelazJ]

Hi,

Thanks Nyall. Indeed, these are PG provider tools. I dug a bit and found
out that list is designed for array field type while key/value refers to
hstore field type.
Doc is updated (might be light but better than nothing imho).

I don't know whether it's of interest, but note that I also have
qgis-rel-dev and qgis-dev installed and in these "branches", there are
fTools and GDALTools folders but those are empty (except the "Tools" folder
also empty).
However for any QGIS version, these two plugins are listed in the Plugin
Manager.

Re: [QGIS-Developer] issues in QGIS Server 2,18

[René-Luc Dhont]

Hi giovanni,

I'd like to try the WFS QGIS Server service ?

Regards,

René-Luc

Le 28/03/2018 à 12:38, Giovanni Manghi a écrit :

Hi all,



I have found the reason why QGIS Server 2.18 and probably 3 are slower
than 2.14 in generating GeoJSON.
I'll fix it.


I discovered two more WFS related issues, one in QGIS Desktop the
other in the Server.

I setup a WFS service, with both QGIS Server 2.18 and Mapserver, with
a layer than contains 5.6million points.
The QGIS WFS client pulls this layer without issues, but there is a
big problem when identifying features with the option "auto open form"
enabled:
on the second identify operation QGIS freezes and it start to leak
memory until it eats it all. It does not happen if the "auto open
form" option is not enabled. This happens also on QGIS 3.

The second issue is about the same dataset published as WFS with QGIS
Server, when saving the layer using QGIS using "save as" (for example
to a geopackage) the result is missing several features/points.
I tried then to save the layer using ogr from th CLI, and at some
point the message "ERROR 1: XML parsing of GML file failed : unclosed
token at line 109413441, column 21" is shown. This is not happening
(and the result is complete) if server used is Mapserver.

I can provide the services URLs is someone wants to give it a try.


cheers!

Re: [QGIS-Developer] QGIS Plugins transfer question

[Richard Duivenvoorde]

If I'm right you can change the 'maintainer' in the plugins website (and
eventually metadata.txt in your plugin).

Log in, go to your plugins, go to 'Manage' tab and Edit there.

If you do not see the Manage tab, let us know.

We are talking about your own plugins isn't it?
Or is it about transferring owner/maintainership from 'orphaned' plugins?

Regards,

Richard Duivenvoorde

Re: [QGIS-Developer] PyQGIS - how to handle primary keys in geopackage

[Alexandre Neto]

Thank you Nyall!

That solved the problem. I failed to see that in the C++ code for split
features tool, but it was there.

The only small annoyance that I had was the need to convert the result of
feature.attributes() into a dictionary.


Once again, thanks! It solved a long-standing issue in the plugin.

Alex

But it for the clarification.
