Re: [QGIS-Developer] Lat Lon Tools - Releasing for QGIS 2 and QGIS 3

[Tom Chadwin]

I'll probably do exactly that. v3.x for QGIS3, continue with v2.x for QGIS2.

[QGIS-Developer] Lat Lon Tools - Releasing for QGIS 2 and QGIS 3

[C Hamilton]

I was able to successfully convert Lat Lon Tools to work with QGIS 3. The
code for QGIS 2 and 3 are incompatible so is it best to keep two parallel
developments going and to keep the release number for the QGIS 2 version at
the 0.8.x and start the release number for QGIS 3 at 1.0.0 and continue to
release both to the same plugin repo? What is the best practice?

Until QGIS 3 is officially released I probably won't release the QGIS 3
plugin as often as the QGIS 2 plugin.

Thanks!!!

thanks for this. I understand it may still be early for coding, unless
people @OTB have plans to support OTB6 also on 2.18 (if this is not too
complicated). I think it would however be good to start with the basics:
creating the repo/transferring owneship, etc.
In this way the work can start soon after the API have reasonably
stabilized (I imagine around June or July).
All the best.

+1M

not having the possibility to stop (without having to kill QGIS) long
queries and having the SQL blocking the main QGIS GUI is really a very
bad user experience compared to other tools that allow do the same
operations (ex. PGAdmin).

This is good to know. On github, I saw that there are plans to move the
plugin into core but it was not clear if there was a decision or how far
the idea progressed.

[QGIS-Developer] how to find all features from original data in filtered layer

[Richard Duivenvoorde]

I have a TimeManager-handled layer, meaning a layer which has a filter 
on it based on a attribute 'time'. So the layer has a subsetString.


Say, the total hour based dataset is 24 hour, so I see 1 hour at a time 
(using TimeManager)


BUT now I want to select all features from the original/whole dataset 
based on another attribute (usecase: select 1 feature and find others 
based on the value of one attribute of that feature, and show the count 
in total set).


I tried something like:

l=iface.mapCanvas().currentLayer()
request = QgsFeatureRequest()
request.disableFilter()
it = l.getFeatures( request.setFilterExpression( u'"device" = 
\'NL1212\'' ) )

i=0
for f in it:
i += 1
print "{} {}".format(i, f['gml_id'])

But still I get just 1 result.

Looking into the api I found: 
layer.dataProvider().featureSource().getFeatures(), but that already has 
the subsetString set


Anybody a clue or workaround (loading the data a second time in a hidden 
layer??)


Regards,

Richard

Re: [QGIS-Developer] OTB 6 and Processing

[Alexander Bruy]

Hi,

I suggest not to rush with releasing and publishing any of the plugins.
Please don't forget that QGIS 2.14, 2.16 and 2.18 still have all providers
built in. For master I personally don't see any benefits in releasing
Processing providers right now. These plugins will be broken most of the
time as Processing suffers from major refactoring, QGIS API also is not
stablized yet.

As Victor said, if someone wants to take ownership on R provider, I wlll be
happy to move it. Otherwise I will try to do my best to keep it working.

Just my 2c.

[QGIS-Developer] Postgis loading using COPY instead of INSERTS?

[Régis Haubourg]

Hi all,

I realized that QGIS only loads datasets to Postgres using INSERT commands,
which is very slow for big tables, and could propose to use COPY commands
with a parameter to choose how many rows are sent in each bulk COPY
command. (see [0])

I tested drag and drop in browser and dbmanager (in 2.18.7 and master) and
 couldn't find anything about that in the issues or the code base.

Did I miss something? Is there someone working in that area?

Thanks for your lights

Régis

Re: [QGIS-Developer] OTB 6 and Processing

[Victor Olaya]

Hi

The repo with the plugin already extracted and prepared is in here

https://github.com/volaya/qgis-otb-plugin

IT hasn't been published in the plugin repo, though. I think the OTB
team was ready to take ownership, so if anyone tells me the user name
or group that will accept it, i will transfer this.

The OTB user days sounds great, but unfortunately, I will not be at
home during those days (there is the spanish foss4g on 1-2 june, and i
will stay in Spain after that to visit my family). In any case, we can
set up a meeting and i can go to meet the OTB team in Toulouse in a
different date.

Let me know what I can do to move the repo ownership, so we can have
the OTB plugin released ASAP

About the R provider, we are in the same situation. The plugin is in
Alex's github account, but if anyone from the R community wants to
take ownership and take care of managing and releasing it, I guess we
can move it.

Cheers

Great news, thanks.
AFAICT the first step is creating the subplugin, taking the removed code
from Processing. Probably Alex and/or Victor could give a hint on how to
best do this.

Thanks Rashad for your prompt reply. I think Victor, Alex, and Nyall
(who is refactoring Processing for QGIS 3 and porting it to C++) are in
the best position to reply.
From my point of view, I think I'll interpret the feelings and needs of
thousands of users saying that we cannot miss OTB from Processing. Same
for R, this has been raised recently on the mailing list.
I think the steps are:
* create an independent provider (sub-plugin of Processing) for OTB
* publish it on the official repo.
Rashad, would you be willing to take ownership of that plugin?
All the best, and thanks again.
