Ok, NOW I can reproduce it :-)
Found another service which had this.
But only on Windows (several QGIS versions).

Created an issue:

Thanks for letting us know.

So it is not the capabilities request that is failing?
I just tried to reproduce this both on Linux and Windows, setting the
cache  to 0 and connect to a geoserver instance, and all goes well.
Both capabilities and getmap requests.

Can you maybe install the 'QGIS Network Logger' plugin? And see what
requests QGIS is firing to the server?
And maybe try to replay those requests in a browsers?

Others can reproduce this?

Hi Andrea,

Can you provide a situation I can reproduce (OS, QGS version, service,
how you load the caps etc) ? Because this would be a proper issue!

But I cannot reproduce it with 3.4, 3.8 or master that I have running
here on Debian.

So if you have a good reproducable case, it sounds like it should be fixed.

Thanks,

Richard Duivenvoorde

Re: [Qgis-user] Not valid data source on wms layer access for QGIS 3.8

Hi, Richard,

I like to reproduce what you are reporting me:

So I guess you are seeing the two styles definition and treat it as
two distinct layers . They instead are only two styles of a layer.
Also one of them is the default style.


No, I definitly saw more layers (like 20 or so).
My 10 was just a guess, but the layers lists were clearly not the same


I like to understand better what is this.
But I don't understand what you mean with "opened that node on the
browser" . You mean a special browser inside QGIS ?


Yes I mean the Browser panel in QGIS, with the 'node' I mean the node in 
that Treeview of wms layers.


But maybe you are right. Maybe it was caching I was looking at?
Is it possible that that same WMS url has been used for a totally 
different set of layers?
And that QGIS maybe at one occasion showed me a fresh response, and a 
second time an (old) cached response?

In Options/Network you can clean the cache.

Anyway, I cannot reproduce it anymore now. I always get the same 10 
layers in both QGIS versions.

I'd say there is something wrong with the server (different endpoints?
url rewriting? proxies?). Because depending on the time and version I
get different results all the time:
- started with QGIS Master and the normal WMS dialog: I saw 10 layers
and could load the aerials
- same session, I opened that node on the browser and then saw MUCH more
layers (a lot of vector layers 'added') and could all load them
- started 3.8 and saw the layers but could not load them
- started master again and saw both in dialog and in browser only the 10
layers
- now I keep seeing only the 10 ortho's (and can load them both in
Master and 3.8.0 which I have here.)

This is the url QGIS fires:
http://www502.regione.toscana.it/ows_ofc/com.rt.wms.RTmap/wms?map=owsofc&SERVICE=WMS&REQUEST=GetCapabilities
as curl command
curl
'http://www502.regione.toscana.it/ows_ofc/com.rt.wms.RTmap/wms?map=owsofc&SERVICE=WMS&REQUEST=GetCapabilities'
-H 'User-Agent: Mozilla/5.0 QGIS/3.9.0-Master'  --compressed

My guess is there is something with the service...

Can you maybe sent me a saved project with a layer that does not load
with you?
Can you try to install the QGIS Network logger plugin to see and check
the url's (and replay the urls in the browser)

Richard

I've told people to use this too... untill people received latlon
coordinates while looking into another crs project. Would it be feasible
to make this "coordinate line edit" CRS aware?
Like: for a project, you define which crs you want to see there. And
then that coordinates used there should be in that crs too.
Mmm, thinking about this... then that is not connected anymore to the
Scale and the shown EPSG code

Ah wait. FULL STOP

now see that the Lat Lon Tools plugin actually ALSO shows Lat Lon
coordinates in the Status bar!
AND that you can change which crs you see there in the settings.
AND that you can copy the coordinates in that crs to clipboard
AND that you see a big crosshair if you use the Zoom to Lat Lon
functionality

Thanks Chris!

Re: [Qgis-user] Geopackage raster layer names are blank

[Richard Duivenvoorde]

Hi Richard,

Please create one or more issues for this:
https://github.com/qgis/qgis/issues

Seems not so much as a bug,
but more like it is 'just not implemented yet'...

Would be helpfull if you provide also small gpkg which then can be used
to check/code. Preferable with yours (rasters only) and from the other
person (vector and raster).
And a good list of what works and what does not :-)

[Richard Duivenvoorde]

Update from mirgration team:

Hi @all,

The issue migration from Redmine to GitHub is going on smoothly (but slow).

The first phase (moving the issues) is finished. All 19845 issues are
now on GitHub :-)

Since the issue ids have changed, we started a second run to replace
old ids with the new ones. This second phase is faster than the
first one. It will take about 9 to 10 hours (we are able to update
+-2200 issues per hour and we have almost 20k issues).

To prevent people for changing or comment issues, we will keep the
interaction limited to developers with push access, until the migration
is complete. Developers with push access can do PR and MR (but can also
enjoy the weekend ;-).

So, we expected to have the migration finished today by 22:00 (GMT+1)
(London time).

Thanks for your comprehension!

Do you really (really) need IIS?

Recently to me it was pretty easy to install QGIS-Server in Apache(!) on
Windows using Osgeo4w64 (and I just retested this on my Windows10 virt mach)

From: https://www.apachelounge.com/download/
I downloaded both httpd and the fascgi-module

Unzipped in (proposed/recommended) C:\Apache24

With Osgeo4w64 (in C:\OSGeo4W64) I installed qgis-ltr and
qgis-ltr-server (in 'web').

Note that Osgeo4w64 does not really install apache+qgisserver, but it
creates a working config + qgisserver. You find the conf here:

c:\OSGeo4W64\httpd.d\httpd_qgis-ltr.conf

Copy that one to your
/conf
directory, and include it in the main httpd.conf by adding:

Include conf/httpd_qgis-ltr.conf

in your conf/httpd.conf

httpd_qgis-ltr.conf (note the different - and _ ) contains all those
magic environment vars:

DefaultInitEnv O4W_QT_PREFIX "C:\OSGeo4W64/apps/Qt5"
DefaultInitEnv O4W_QT_BINARIES "C:\OSGeo4W64/apps/Qt5/bin"

SetHandler fcgid-script
Options ExecCGI
# NOTE: this is for Apache 2.2 You need Require for 2.4 !
#Order allow,deny
#Allow from all
Require all granted


I had to remove the "Order ... " part and add the "Require " parth.

But after that I had a working QgisServer (in Apache)  \o/


Off course, useless if you really need IIS :-( .

But the crux in all this (both in IIS and Apache) is to have all the
proper environment variables and paths in place.

http://www.itopen.it/bulk/qgis3-server

is a very good source for that. Eg vor all he Fcgid variables (talking
Apache here, not sure how this is in IIS):

http://www.itopen.it/bulk/qgis3-server/#/step-16

I would recommend:
- if you can go for Apache on Windows, use that
- if you can go for Linux, use that
- if all that fails: use IIS on Windows

But sorry no experience with that.

Regards,

Richard Duivenvoorde

Boaz,

I do not think anybody can help  with such few information you provided.

I just tested and with me I can create layout and edit the legend of it.

Is that with ALL your projects? Or just one?
If so can you provide an example project?

Best in such cases is to give all information you have to make it
possible for others (not even devs) to reproduce your problem.
As that is the first step to be able to fix.

Can you provide a minimal project to reproduce? Then best is to create
an issue for it.

Hi Gary,

I'm not an expert in this format (never heard of it to be honest :-) ).

But if you write "I can import it", does that mean it is only read as a
plain image? That is if you move your cursor you see the x,y PIXELS
instead of coordinates on the bottom of QGIS? Meaning QGIS read it as a
non georeferenced image.

OR did QGIS already took some georeference-info (the .hdr) into account,
and you see actual latlon coordinates there?

Note that QGIS opens it's rasters via GDAL so GDAL should have a driver
for it to work in QGIS

Re: [Qgis-user] problems with raster (merge, clip) and crash dumped

[Richard Duivenvoorde]

And in addition of Nicolas idea of upgrading: I'd try to create an issue
with a (small) .asc file which makes QGIS crash, AND the exact steps the
user is doing when it crashes, see

https://qgis.org/en/site/getinvolved/development/bugreporting.html#reporting-issues-on-qgis-applications

This indeed looks like locale/data related problems. Which is maybe
already fixed in QGIS3 or can be fixed by changing the data?
But creating an issue could maybe make QGIS handle these data issues better.

HTH, regards,

Richard Duivenvoorde

I think just the normal way.  Or do you think there is a usecase for
such a 'fire-edit and go'?

But some already convinced me that (at least adding it to the context
menu) is 'gui cluttering'.

Still interested in other 'Papercuts' though :-)

[Qgis-user] [Papercuts] Open Attribute table and make editable in one go

[Richard Duivenvoorde]

Hi,

Got a question from a user, if it is possible to open the attribute
table and make it editable in one go, to easily change something in some
little layer.
Instead of: make layer editable open attribute table.
Or open table and click pencil to make it editable.

I am aware that the double click action on a layer is configurable in
Settings/Canvas & Legend, so the opening of the table is easy :-)

Seems easy to add, so I'm wondering:
- are others interested in this?
- would I add this to the context menu (then how?)
- would I add it in the Settings dropdown (as an extra item 'Open
attribute tabled editable')
- both?

Regards,

Richard Duivenvoorde

PS adding tag [Papercuts] here, as I hope people will post more little
tweaks/annoyances using this tag for things they think are small work to
do but make working in QGIS much easier/nicer.

Hi Piotrek,

I had a look into this, also because I have a PR for timemanager open to
try to 'guess' these kind of information based on the capabilities of
the service... Which is hard because a lot different dimension formats
are possible, and a lot of mapservers (notably the Minesota Mapservers)
are badly configured! Geoservers do often a better job as they determine
the time 'extents' based on the actual data.

Anyway, in your case:

Capabilities of the wms is:

http://ies-ows.jrc.ec.europa.eu/effis?SERVICE=WMS&REQUEST=GetCapabilities

Which standard returns a wms 1.1.1 capabilities document apparently :-(
(while QGIS nowadays favours 1.3.0)

As an example have a look at this layer:  "ecmwf.fwi"
in the capabilities the 'dimensions' for this layer:

2018-01-01/2099-12-31

So: no indication of the periods (like better wms-t's do nowadays), so
we are guessing this is day-based data... running from 2018 till 2099:
nope, they are just saying that!!
( if I were you I'd ask jrc to do some reconfiguring :-) )

The real data is from 2018-05-15 till 2019-05-07 ... !!

So: just load the layer in QGIS as wms,
Open time manager, point to the rasterlayer and use as starttime:
2018-05-15
and as endtime
2019-05-07
then the plugin will determine the right time format: %Y-%m-%d

Now make sure you put the slider somewhere between the begin and endtime
and 'Time frame size' to one day.

Then it works.. with me, hope it does for you.

Regards,

Richard Duivenvoorde

ps if adventurous (and running qgis 3.6 you can use the networklogger
plugin to see the actual requests qgis is firing, preliminary version
here:
https://github.com/rduivenvoorde/qgisnetworklogger/tree/model_rewrite )

ps2 I think my PR in timemanager will make adding this kind of layers
easier, though it is hard to handle all possible versions and dimensions...

[Qgis-user] QGIS, gdal_contour and numerical label formatting...

[Richard Duivenvoorde]

Hi List,

I have a (smoke dispersion) raster model output of which I want to have
contour lines.
One special/strange condition: contours should be on 0.0001 (1.0E-4)...
(apparently gdal)

QGIS/gdal_contour to the rescue:

http://duif.net/temp/labelnumbers.png

But as I demo'ed this to somebody, some things came up:

- if you use gdal_contour in processing in QGIS  with a temporary layer,
then you create a SHAPE file with (default) column type 10/3 so all
values are show as 0.000 
BUT, if you let processing save to geopackage (as in screendump), you do
NOT have this limit.

Question: would it be feasible to move to geopackage as intermediate
format in processing (at least for gdal_contour)? Is this easy to do?

- if you open the attribute table of the contours, there is an ELEV
column with type 'real' but the values you see in the labels in the
image are the same as you see in the attribute table
While if you open the geopackage in slqitebrowser, you see values like
ordered: 0.0001, 0.0002,  etc without the trailing 10 numbers..
Going to geojson, it looks good too (and saving that one to gpkg... is
ok too)?

- the (number) labels look awfull?

Question: how determines QGIS how to show floats/reals in the attribute
table? Is that something we could influence? Or is that 'not done', and
should I create a text column from the real column?

Question2: for what I can see you can influence the format of TEXT in
the label tools, but you cannot influence the format of NUMBERS, am I right?

Would be a nice feature I think? (or is this overkill, and should I go
the number->text way)?

Thanks for any input or pointers.

Wanne play? http://duif.net/temp/smoke.zip is an example epsg:4326
raster smoke plume.

Regards,

Richard Duivenvoorde

If I open attached mini csv, I can load it in QGIS, but cannot edit

Hi Max,

The error means that the python-cpp bridge is not working because wrong
paths to (python) libs.
Are you maybe in a Python Virtual Environment at that moment, which in
that case screws up your python path?

Or else: did you miss some QGIS-Python package (if installed via package
manager)?

Can you try to search in the project file?
It's 'just' a zip, so rename unpack it and search for IE or explorer in

Are you maybe behind a http proxy? Because it could be that QGIS is

Works for me on 3.4.5

If you want to see what QGIS is firing exactly, or if you want to replay
the WMS requests in a browser or using curl: install 3.6 or the nightly
dev version of QGIS and get this plugin:
https://github.com/rduivenvoorde/qgisnetworklogger
It's not yet in plugin repo (and only for 3.5 and further, because it
needs work done by Nyall), because it slow's down QGIS after a couple of
hundred requests.. but for your problem it is perfect

I think if you do not want to release the underlying data, the only
solution is to run a WMS-server with your data ( preferebly QGIS-Server
:-) ). Then you only server images. and it is harder (but also not
impossible if you want to show featureinfo data) to harvest the data.

You could even use the same ol3 html viewer you use now but change the
ol.source.Vector-layer to an WMS layer in the layer.js file.

But... you need a QGIS-server (or other WMS) for that to work, and some
knowledge of OpenLayers/Javascript coding.

Hi Jeroen,

If this works (na if this actually the same issue), can you maybe update

https://issues.qgis.org/issues/16742 ?

to show how you did it, so others can find it?

Re: [Qgis-user] change default webbrowser in qgis3 settings?

[Richard Duivenvoorde]

Hi Jeroen,

I'd say: create an issue in the repo of it:
https://github.com/tomchadwin/web2qgis/issues

I have some plugins which opened an url or file in a browser, and then
used default Qt-machinery, something like:

QDesktopServices.openUrl('http://qgis.org')

What happens if you use that in the Python Console? In your QGIS 3.
Does it open your preferred browser?
Or does it also open IE. If last, then maybe it is a Qt setting?

Regards,

Richard Duivenvoorde

Yes, I often give it a very big red dot or line, so to show me I miss

Well, if both QGIS versions fail to load it, I would think it is as the
error tells you: not a valid geojson file.

Can you share the data? (parts of it? It is a text file, be sure to sent
both the start, and and some features).

Else does a site as http://geojson.io/ open your file?

With me it is still there (QGIS 2.18.28): right click in layer manager,
select 'Save As' and then in the dialog select Geography Markup Language

To be honest I'm not so much a user of the Layout-part of QGIS, but
shouldn't the a North arrow be an essential property of a map, AND
should the North-arrow not always point to the North of the given crs?

Trying out here in a layout, if I rotate the map 10 degrees, the arrow
image is fixed to top. Or do I miss something, like that you can 'fix an
image to the north' or so?

Another question that pops up: are all crs's always pointing to 0
degrees North? And if not is a crs aware of that?
If so I would opt for either some function to have an intelligent North
Arrow in layouts (which are aware of crs, so rotate with map), and which
can reuse the image dialogs?
Or add such intelligence to the already image props (besides a North
arrow I can think about images of a ground level which always have to be
horizontal or so)?

Sorry for popping up this questions...

Regards,

Richard Duivenvoorde

Because locator filters are supposed to be separate blocks, and because
I'm not interested in Google or Swiss geocoders, and all have a special
way to handle stuff.
I created a Locator (please try it out) for Nominatim and for our
National Geocoder service. As that is where my knowledge and interests
are. Denis did one for the Swiss Geocoder and others probably for their
ones.
I think in case of Locators it is better to not pile all on one heap :-)

Re: [Qgis-user] Impossibilità connessione repository Qgis 3.4 e WMS

[Richard Duivenvoorde]

Hi Giuseppe,

Your repo url is just fine, QGIS will add the version behind it and that
one works:

https://plugins.qgis.org/plugins/plugins.xml?qgis=3.4

Maybe a connection issue on your side, or a server hickup on ours?
Please try again.

Your WMS url works fine with me too, opening it in a web browser gives
an arcgis error, but if you create a WMS connection with it I can load
the layer:

Volo_ATA_1997

in epsg:3004 which looks like this: http://duif.net/temp/italy.png

Are you sure your connection is ok?

Hi Micha/Juergen,

I'm on Buster, and compile 2.18, 3.4 regularly and master almost daily.

I don't know the packaging details, but is qtbase-abi (still?) a
necessary dependency or is it maybe possible to remove it?

@Micha happy to sent you some lines to compile it and install it in your
home dir, after the first steps it is pretty easy to do. You can have a
daily fresh backed master version then :-)

Yep agreed, this would be my top speed killer investigations:

- check with a fresh profile (or even rename the folder beneath it, so
you get the 'hey upgrading from 2.x ?' message
- really stop Windows virusscanners (that is: as admin also stop all
scanner related services, and not that they are not 'autostarted'
again...).
- have a look at your Windows network drives (I know some years ago
there were issues with getting big files from network drives on Windows)
- thin client issues: sometimes thin clients are really too thin for
serious work, but I've also encountered issues on more hefty clients
- browser issues? I sometimes see the 'scanning' of folders containing a
lot of geodata in QGIS browser panel is taking some cpu resources.

Can you try to start QGIS with the following options:

qgis --noversioncheck --noplugins --hide-browser

(with me this takes 2 sec to start)

My gut feeling is that python is slow in certain Windows environments.

Last: see if on another pc you have the same issues, if possible?

[Qgis-user] Netcdf guru? Plz have a look

[Richard Duivenvoorde]

Hi List,

Most know that Peter P is busy creating MDAL dataprovider to be able to
load meshes [0].

Myself I did my first steps in creating a small netcdf using python with
3x7 cells and was puzzled by what I should see: 2x6 or 3x7 cells.
Depending on the way you load the data, QGIS shows different versions
(Geoserver as wms shows 3x7, Panoply shows 2x6 OR 3x7 depending on if
you use interpolation or not).

I created an question/issue for this [1]

But maybe some experienced netcdf user can tell us something about this?

And IF you are a guru :-)
Can somebody point me to a small projected netcdf (CF 1.6) so I can try
to create those (using python) too? Preferably this netcdf has some
time-slices so can be used as a WMS-T in Geosever AND loaded as Mesh in
QGIS (and show time-data). IF possible: epsg:28992 ...

Regards & Thanks for any pointers,

Richard Duivenvoorde

Hi Robert,

I think you hit some kind of wfs-data issue here.

If I open the url in a browser:
http://openapi.aurin.org.au/public/wfs?SERVICE=WFS&REQUEST=GetCapabilities&VERSION=1.1.0

Or time it using curl:

time curl
"http://openapi.aurin.org.au/public/wfs?SERVICE=WFS&REQUEST=GetCapabilities&VERSION=1.1.0";

real0m20.490s
user0m0.090s
sys 0m0.716s

You see it is not a fast service, but seemingly ok.

What I do see is that the 'Abstracts' of the layers are very strange
formatted, looking like it is instead of a string some serialized java
(see below).

Mmm, requesting the service again, I see the file is just HUGE (56Mb)
and containing what looks like escaped html from some australian census
website...

So I think somebody has to fix that service first...
(I was creating an issue for it because QGIS should not fail on
capabilities I though, but this output is t strange (and 56Mb large)...

Regards,

Richard Duivenvoorde

Hi, wms works for me.

Proxies in corporate/governmental environments often play up with me too.
Please try out some options in Settings/Options/Network/Proxy settings.
Check the 'Use proxy for web access' and use the right type (default
should work, but else try the HttpProsy).

Hi Morten,

My last conclusion was simply wrong (the one with the crs problem), I
copied-pasted the wrong url (added the : on the end).

This part:

2018-10-12T11:43:25 WFS[1] Server generated an exception in GetFeature
response: java.lang.RuntimeException: java.lang.RuntimeException:
java.io.IOException
java.lang.RuntimeException: java.io.IOException
java.io.IOExceptionCannot do natural order without a primary key, please
add it or specify a manual sort over existing attributes

is a java exception, so is thrown by your(!) geoserver.

The url QGIS is firing (also in the stacktrace):

http://wfs1.erst.dk/fingerplan17/wfs?SERVICE=WFS&REQUEST=GetFeature&VERSION=2.0.0&TYPENAMES=fingerplan17:test&STARTINDEX=0&COUNT=1&SRSNAME=urn:ogc:def:crs:EPSG::25832

Means that QGIS is asking for an ordered(!) feature list (with
startindex and count). QGIS does this because a WFS 2.0.0 server is able
to page through it's features, meaning you can request eg 1 features
in steps of 2000.

So to be able to do this (that is, to be able to only server every
feature ONCE in between this serie of steps), your server has to be able
to determine the uniqueness of your features. Meaning your data(!) has
to be a primary key. Meaning if you have a database there should be
either a primary key on one of your columns, OR you add a
'Unique-Constraint' on an (unique) column.
And that is I think why Geoserver is complaining (and QGIS is receiving
this error message instead of a set of features).

That is the reason QGIS is only able to open your dataset with an WFS
1.0.0 request (WFS 1.0.0 does not have 'paging', so Geoserver is not so
picky about the structure of your data).

So it is a combination of issues in the geoserver setup, data and the
fact that QGIS is getting 'smarter' and tries to page through data.

HTH :-)

Richard DUivenvoorde

Hi Andrew,

What are you looking for in the Vector Toolbar?

As you can see here:
https://gis.stackexchange.com/questions/183454/qgis-vector-toolbar-has-no-tools

There is nothing, unless you for example install the 'Coordinate
Capture' plugin in QGIS3

After installation of that plugin it will at least contain one button,
and you should be able to view it via the context menu in the toolbars-area.
If that fails, you can use the Python console and do:

iface.vectorToolBar().show()

and to hide it:
iface.vectorToolBar().hide()

HTH, Regards,

Richard Duivenvoorde

Hi Morten,

From the debug info:

Firing:

Then your server has troubles serving data without primary key:

which, when put in a browser says:

Unable to support srsName: urn:ogc:def:crs:EPSG::25832:
No authority was defined for code "EPSG:". Did you forget
"AUTHORITY:NUMBER"?

QGIS is not handling this apparently? As the dialog with 'Load features

Hope this helps a little,

Hi Kurt,

I've seen this myself when the server, which is serving the
plugins.xml's is too busy building QGIS packages.
Short term, it is best to try later again, longer term we have to tackle
this problem by maybe moving one of the jobs to other servers.

Hi Andrea,

I use several WMS (Geoserver) over https (and I checked: using http
being redirected to https also worked).

Do you have an url we can test?

There is also the

Re: [Qgis-user] Provider Error

[Richard Duivenvoorde]

Mmm, that should just work.

Is the shapefile maybe in a zip?
Is it read only on the file system?
If you save it as (another) shp file, does it behave the same?


Else: can you sent me (a part of) the shp so I can test here?

Re: [Qgis-user] Provider Error

[Richard Duivenvoorde]

Depending on the type of provider, you can or can not add fields.

Eg, if I'm correct a csv file will not work.

You can see in the properties of the layer what the 'capabilities' are
of a provider.
So to make this possible, you could first create a geopackage or
shapefile from it? And then back?

Regards,

Richard

Hi Lene,

I had a look, your userid is a osgeo-userid (so you can also login with
it in the plugins website, and several osgeo services).

To reset your password (and receive a reset link), go to:
https://id.osgeo.org/ldap/reset

To update other osgeo-info (after you login), go to
https://id.osgeo.org/ldap/edit

Hope this helps.

We had already long discussions about changing issue trackers, see older
threads: short version: unless somebody takes up the lead and creates a
firm plan to move, we will not move. There are some tests going on, but
we are not in a hurry.

Regards,

Richard Duivenvoorde

You should be able to find the panel via the menu 'View/Panels' too (or
by rightclicking in the toolbar to see the list of available panels and
toolbars).

Depending on you needs you could also try my 'Nominatim Locator Filter'
IF you only need to search-zoom to a place on the world. Read some info
about it here:
http://www.qgis.nl/2018/05/16/english-coding-a-qgslocator-plugin/?lang=en

This is actually a locator, so you use the locator in the lower left
corner. Caveat: you have to end you search with a space, because the
Nominatim service does not allow you to use it as a 'search while you
type' service.

If you need to download the data, you really need the Osm  Place search

Hi Andrea,

Can you try it with a new configuration (as rename your .qgis2 dir to
start with a fresh one)?

Historically this kind of behaviour had to do do with rogue plugins...
So first thing is to check if a plugin is doing this.

Re: [Qgis-user] Delete key does not remove item in composer

[Richard Duivenvoorde]

I can reproduce:

in english both keys work, but if I start QGIS in German:

qgis3 --lang de

then only backspace works, del does not

(My OS is Debian english, US keyboard, LANGUAGE=en_US:en

Please create an issue for it (and preferably try some other languages
too :-) )

[Qgis-user] We need some help...: add some

[Richard Duivenvoorde]

Hi Users/Devs,

please everybody have a look at the upcoming list of features for 3.2:

http://changelog.qgis.org/en/qgis/version/3.2.0/

If you think a Feature is interesting, you know something about it, OR
you want to learn something about it? Pick it up, adopt it, and add an
image or some more specific text.

My plan is to move the entries to the website within a couple of days
after the release of 3.2  (so very very soon...). And not wait untill
the changelog is filled.

If every user picks a  feature to create some screendump, it is done
within minutes ;-)

Regards & thanks for the help.

Works like a charm.

Thanks Frank for the tip! Quick and easy:
- copy a feature
- paste as memory layer
- put it on top
- choose 'Inverted polygons' as Symbology
- fiddle with transparency

Is worth a blog post somewhere if you ask me :-)

Re: [Qgis-user] Copying styles issue in 3.0

[Richard Duivenvoorde]

On 2018-06-18 09:05, Patrick Dunford wrote:

Good day

It appears since 3.0 that there is a problem when a style is copied
from one layer to another.

In the previous editions I can recall value maps for specific fields
would be copied between layers.

In 3 I am finding the value map is not copied, meaning each value map
has to be laboriously copied by hand as there is no means of exporting
a value map from an existing layer.

I have found value maps are not copied between shapefile layers, or
from a shapefile to a geopackage. All other style data appears to copy
successfully.

Do you have any comment or should this be filed as a bug.


Hi Patrick,

no comment (as I did not encounter this yet), but this sounds like an 
issue, so I would always file an issue first, adding some 
data/projectfile/steps to reproduce. And then sent an email to the dev 
list pointing to your issue.


Then it is (even for non devs) easier to reproduce and confirm, and devs 
are more sure it is an actual issue to be picked up.

[Qgis-user] Gentle reminder: please test 3.2 RC and update Visual Changelog with your work items

[Richard Duivenvoorde]

Hi Devs,

With QGIS 3.2 coming near...

Please devs: add items too our visual changelog,
so if downloads start we will have something to show (off):

http://changelog.qgis.org/en/qgis/version/3.2.0/
It should be a little easier now
(@Tim, no more approval needed if I'm correct...?)

And for users: please test our latest development version!
Really fresh builds you can updated every day come in via the OSGeo4W
installer.
But if that is too much for you, you can test your work process by using
a weekly build standalone installer:
https://qgis.org/downloads/weekly/?C=M;O=D

And for all (also wannebee) devs: please take the time to clear up some
issues of current master:
https://issues.qgis.org/projects/qgis/issues

Hope 3.2 will be the best release ever (well at least untill the one
after that ;-) ).

Regards & Thanks,

Richard Duivenvoorde

Hi Calvin,

Does that not mean you could use svg symbols for this?
I know parts of svg is made dynamic, as you can define the color of svg's.
I'm not sure if you can make other parts of an svg dynamic too?
Would be cool to be able to use expressions for example to
color/rotate/size svg symbols?

Another thing I was thinking about: did you explore the geometry
generator stuff?

So this appears to be a Mac only problem?
Only thing that has changed is that Cloudflare is now in the middle...
Could it be that a mac is caching the certificates or so?


Can somebody with a mac (and having this problem) try to run the
following in a file in the Python console?



from qgis.PyQt.QtNetwork import QNetworkRequest
from qgis.PyQt.QtCore import *

def handle(reply):
print ''
print reply.url()
print reply.attribute(QNetworkRequest.HttpStatusCodeAttribute)
print reply.attribute(QNetworkRequest.HttpReasonPhraseAttribute)
print reply.error()

def sslproblem(reply):
print 'ssl problem'
print reply

def test():
nam = QgsNetworkAccessManager.instance()
nam.finished.connect(handle)
nam.sslErrors.connect(sslproblem)
url='https://plugins.qgis.org/plugins/plugins.xml/?qgis=2.18'
nam.get(QNetworkRequest(QUrl(url)))

test()




With me this results in:

PyQt4.QtCore.QUrl(u'https://plugins.qgis.org/plugins/plugins.xml/?qgis=2.18')
200
OK
0

Please report back if different.

Look at the source (Luke :-)), of the page. You should see something

Nope, nothing changed. We have had a one-time hickup in the service in

Cloudflare.

IF it fails can you then check in a browser if

Hi Patrick,

in the footer of the page you will find a 'fixme' link. If you click
that one, you will be sent to a github page:

https://github.com/qgis/QGIS-Website/edit/master/source/site/forusers/alldownloads.rst

AND probably be asked to create a fork of the repo (do it) and then you
can do a rewrite and can ask for a pull request, so others can have a
look at your proposal.

Feel free to do it! But do not underestimate the complexity of all the
different setups, exclusions, possibilities etc etc... The different
setups are there for example because one has latest versions of
software, and another one only the stable versions etc etc.

If you can get your head around it, AND do a human write-up that would
be great. Note that this page has gone over a lot of iterations already:

https://github.com/qgis/QGIS-Website/commits/master/source/site/forusers/alldownloads.rst

It is just pretty complex :-)

But maybe a fresh mind could be a win!

Had a quick look, while normally I use QGIS in english, if I start in
dutch I see in debug msg:

../src/app/main.cpp: 1201: (main) [2ms] loading of qt translation failed
/usr/share/qt5/translations/qt_nl

So (as told in the stackoverflow answer) you really need Qt5's OWN
translations besides the QGIS translations to have these things translated.

Searching for qt_nl.qm on my machine it was missing, BUT I found a
qt_de.qm... so starting qgis with '--lang de' I have the right button I
think (see german vs dutch screenie).

So conclusion:
- IF qt-translations is installed, you should not see english OK buttons,
- UNLESS there is just no qt translation (apparently not for dutch/nl,
we should work on that!)

So in the case of osgeo4w, it looks like a packaging issue?

I would be ok with an option in the dialog, though it is hard to promise
that somebody *else* will not open it too in a non readonly mode, in a
networked work environment ...

Is it a possibility (at least on linux) to look at the file permissions?
That would open the possibility to put a read-only (permissioned) file,
and in that way you would promise to not edit/delete?
There have been other issues also with the wal-files (eg browser was
also rescanning dirs etc), so it would be cool to come up with / invest
in a good solution?

Re: [Qgis-user] How to open QGIS from another application?

[Richard Duivenvoorde]

In addition, you could create a 'default project' which is started by
QGIS (or started because you use the command line option).

You can also let QGIS start up with a python script. Which could do the
things like zoom in to a certain feature etc. I'm not aware if that
python script receives the original command line parameters. Because if
that is the case, you could also give the x,y on the command line.

Richard

Yes, there is a panel 'Tile Scale' which is working for WMST, and to me
also looks to work for xyz layers:

- open xyz layer (eg osm)
- be sure the active layer is this xyz layer in the layer panel
- via menu View/Panels select 'Tile Scale Panel' (or via context menu in
the toolbars panel)
- now you can use the slider to go to a fixed scale. After that your
mouse scroll will also stick at the fixed scales (as that one does an
exact factor 2 or 0.5).

IF you really always work with xyz layers as reference layers, it is
possible to change your 'predefined' scales which you see in the Scales
dropdown in the bottom status bar of QGIS. Just export those as xml,
adapt the values and then import them.

I wrote something about it some years ago, to adapt those scales to our
national WMTS scales (which is a DIFFERENT schema then the Google/World
schema the xyz layers use!) [0]

Would be nice to maybe create a 'layer tree widget' [1][2] for these xyz
layers?

Richard Duivenvoorde

Ah wait, it is not showing YOUR layer... I was talking about the xyz layer.
Then probably you did not set the right crs/projection/epsg code for
your data?
I think the quickmapservices plugin sets your project to epsg:3857. If
that is the first layer then it will stay like this.
If you first load YOUR layer your project will probably in the crs of
you data (or at least what it tells is the crs of your data).

See in 2.18 what is the crs of the project, and your data and adjust in
3.0 to the same values.

[Qgis-user] Merge vector layers missing from menu in QGIS 3.0

Hi List,

On another mailing list, a Windows QGIS3 user asked why there is no
'Merge vector layers' in the *Vector* =>*Data Management Tools* menu.

In my current master build it IS there.
But in my Windows install it is indeed missing.

Was it layer added?

Will point to processing, but still wonderning.

May I second this call? To everybody interested in some cool QGIS
features: if you earn (some) money with QGIS: what about giving back
some of it to QGIS development :-)

Re: [Qgis-user] [QGIS-Developer] QGIS 3 OS X/macOS

[Richard Duivenvoorde]

Whee, William,

All good news! Congrats with all your life changes too :-)

Though not a Mac owner I've seen a lot of messages about it.

Thanks for this big step!

Is it an idea to put the .dmg file (together with the link to Python 3.6
on the QGIS Website, as 'offical mac installer'?
For the QGIS project it would be a good thing to have such an official
installer on the website.

Another big question (for Mac users), was if it is possible to provide a
'signed' installer. So question would be: IF we as OSGeo or QGIS could
arrange the key for you. Would it be a hassle to sign the installer? Or
are you in other ways reluctant to use this?

Again, thanks for this work.

Regards,

Richard Duivenvoorde

Re: [Qgis-user] QGIS3 location error

[Richard Duivenvoorde]

Which version of proj are you using? See the about box of QGIS.

If it is 500, you hit a proj issue, see this thread
https://lists.osgeo.org/pipermail/qgis-developer/2018-March/052501.html
(or in this list read msgs with subject "proj5 and epsg:3857")

If you have 49* it is another problem.

Richard

Re: [Qgis-user] Error returned from Plugin giswater

[Richard Duivenvoorde]

Hi Tyler,

I reckon this is not a public plugin?

But to my experience, and in my words: your plugin instance does not
have (and therefor KEEP) an handle to some object (QgsAttributeForm?)
which you try to retrieve.

Your python code tries to retrieve an (cpp) object, but the widget you
are referring to is not there (anymore in the cpp world, probably
garbage collected).
Note that all python references are actually references to cpp objects.
See
http://pyqt.sourceforge.net/Docs/PyQt5/gotchas.html#garbage-collection
for probably a better explanation :-)

Are you the author of the code? Then add a reference to it in your
plugin constructor: like:
self.attr_form = ...
This makes

Hope this helps,

Richard Duivenvoorde

Hi Rémi and other mac os users,

We (Project Steering Committe/PSC) contacted former Mac OS packagers,
this weekend, and William/KyngChaos answered:

"It's going slow, but I'm close now.  If I can stay focused, I may have
it ready by the end of the weekend."

So keep an eye on
https://qgis.org/en/site/forusers/download.html
and
http://www.kyngchaos.com/software/qgis

Off course if there is somebody else willing to step in to create (other
type of) Mac OS packages: let us know.

Regards,

Richard Duivenvoorde

Re: [Qgis-user] Linking to the *current* docs

[Richard Duivenvoorde]

Hi Jonathan,

We had this discussion some years ago.

We decided for latest and testing:

https://docs.qgis.org/latest/en/docs/user_manual/print_composer/index.html
is being redirected to:
https://docs.qgis.org/2.18/en/docs/user_manual/print_composer/index.html
but th 2.14 is also still available:
https://docs.qgis.org/2.14/en/docs/user_manual/print_composer/index.html

Current testing/master is:
https://docs.qgis.org/testing/en/docs/user_manual/print_composer/index.html

https://docs.qgis.org/3.1/en/docs/user_manual/print_composer/index.html
is being  redirected to testing

All magic is done with some redirection in the apache.conf so if not
working, let us know.

Regards,

Richard Duivenvoorde

Hi William,

Are you able to reproduce your problem on another machine? To rule out
local install problems?
Are you able to reproduce it with other datasets too? To rule out that
it is a local data problem?

If both true: just create an issue at issues.qgis.org, preferably attach
a small dataset so others can first reproduce your issue on their
machines and then try to fix it.

Much detail is ok, most important thing is that other can reproduce your
problem, so add details about for example Operating System, kind of
Data, and exact steps to reproduce by others.

Regards,

Richard Duivenvoorde
