That should show up the temporal indicator after activating.

What does happen if you put area_result['OUTPUT'] directly instead of
self.parameterAsSource?
parameterAsSource() accept a parameter as first argument and area_result
should be already un QgsVectorLayer.

This is strange, now both Apply and Ok button should to update the min/max

I have GRASS7 folder path set to /Applications/GRASS-7.0.app/Contents/MacOS
and I can see GRASS7 algs list in processing toolbox.
The only problem is that the execution of any algorithm does not generate
any output. No error is prompted.

Also, I just saw this issue https://issues.qgis.org/issues/17555 but I
cannot confirm it on my machine.

For Linestring type you have to use the vertex editor in order to visualize
z values. I don't remember a such functionality.
I guess that for line with a lot of vertices it is pretty complicated to
display all the z values inside the identify results.

Anyway, fpr linestring you should be able to see the z value of closest
vertex at the clicked coordinate.

sure, it is possible. With 2.x version the below example should be working:

>>> vl = iface.activeLayer()
>>> actions = vl.actions()
>>>
>>> actionName = 'Show feature id'
>>> actionContent = 'from qgis.utils import iface;

Since QGIS 3 the code for actions was revamped, please see

Just more info on this issue:
I just noticed that saga commands work correctly when the SRS layers
is not projected (i.e. epsg:4326).
Using UTM projection (i.e epsg:32633) on raster and vector layer SAGA
fails with segfault.

Thanks to take in account this issue.

I am confused, which issue is easy to fix, TauDEM or SAGA or both? and How?
Do you were referring to your ticket (#13279)? I don't see a segfault
there though

Thank you for your quick reply.
The issue is a segfault here and OSX package (QGIS LTR 2.14.8) bundled
with SAGA 2.2.3.
Anyway I don't see a syntax command error as mentioned from the issue
which seems was fixed, at least for the 2.2.x version.

[Qgis-developer] SAGA and TauDEM algs in QGIS from KingChaos package

[Salvatore Larosa]

Hi all,

I have installed 2.14.8 from William Kyngesburye's packages, all ok. I
noticed that almost all the algs of SAGA and TauDEM do not work.

For SAGA (2.2.3) algs I get:

/Users/slarosa/.qgis2//processing/saga_batch_job.sh: line 3: 83064
Segmentation fault: 11 saga_cmd io_gdal 0 -TRANSFORM 1 -INTERPOL 0

-FILES "/Users/slarosa/MU/elevation_utm.tif"

Error: input file

Error: Zone Grid

That was happening with the Zonal Raster Statistics alg. But I get the
identical error (segmentation fault) with the others algorithms.

For TauDEM algs I get systematically an "Unsupported Data Source" error:

is not a supported raster data source TIFFReadDirectory:Failed to read
directory at offset 1991676

Anyone confirms?
Can I exclude a local problem with my machine (OSX El Capitan)?

it should be enough to insert:

[Qgis-developer] different handling of invalid geometries between LTR and master version

[Salvatore Larosa]

Hi all,

I just noticed that when a layer has invalid geometries (e.g.
self-intersections in polygon layer) the editing tool behaviour is
different between master and LTR version.
In LTR version you can fix it manually by selecting the vertices and
deleting them eventually while in master version it is not possible
anymore to select the vertices for invalid geometries.

IMHO, better LTR behaviour as allowing the user to handle the
incorrect geometry by editing it manually in addition to geometry
checker tools.

Thoughts??

Best Regards,
-SL

I don't know if this mail was notified to you, but I am noticing a
strange issue compiling qgis with grass support.

If I use only -DWITH_GRASS7=ON I get a build error (as from codepad
link in the previous mail) while adding -DWITH_GRASS=ON
I can build just fine.

is this the expected behaviour?
is it necessary to have both grass versions?

Thanks,

the date of your revision is a couple of weeks ago (15 Sep), in the

Please try a more recent revision, the crash should disappear.

Attributes map must be updated just after the signal has been emitted
otherwise the attribute index changes before to remove the index
throws the exception on
the attribute form code. It happens only when the attribute table is open.
You fixed a very similar issue recently (#13366)

Actually there are two different issue apparently,  the first one
(Pedro's issue) happens with native field, but it was already fixed
[0],
the second one (mine) happens when creating a virtual field by field
calculator and then deleting it.

Maybe should I file a new ticket for it?

[Qgis-developer] crash on deleting a column (virtual field)

[Salvatore Larosa]

I am experiencing a crash that systematically happens on each machine
I tested, both Windows and Linux, for such reason I am excluding a
local issue.

Before I file a ticket though, I would like to know if anyone can
reproduce the issue. The steps are:

* open the attribute table
* create a virtual field with expression = "other field"
* open delete column dialog (from the toolbar of attribute table)
* the only selectable column is the new virtual field, select it
* ok on dialog
* crash

Thanks for any feedback!

 Because ctids are very flaky - any modification to the row might or will

 loose their selection, subsequent updates or deletes might fail or even worse
 update or delete a different feature.

 Is there a good reason not to put it back?


 +1 for keeping the algorithm log.

 QGIS crashes ungracefully when a python expression script contains an error.

 I think there should be a warning but the crashes should be avoided.

 Crash log from my OSGeo4W install is here:

 Sorry for flooding, but while checking the changelog I'm finding a

 * an empty name of the bookmark
 * a wrong extent.
 Is this confirmed, ora local issue?

I just fixed both the issues.
The first one was due to the lack of some translation string and the
second one I mistakenly swapped xmax with ymin of the bookmark extent
(as reported by Pedro, thanks).


 furthermore, the output dir is not remembered.

also this has been fixed.

if you set flag to NoGeometry you cannot pass the $area function as it

your snippet should to work whether you store the value of $area in a

 Sorry but I didn't understand how to use QgsSimpleMarkerSymbolLayerV2.

 Below there's my code (with only two symbol item as example)

 myTargetField = field
 myRangeList = []
 myOpacity = 1


 # symbol 1
 mySymbol = QgsSymbolV2.defaultSymbol(layer.geometryType())
 mySymbol.setColor(QColor('#FF'))
 mySymbol.setAlpha(myOpacity)

 myRenderer.setMode(QgsGraduatedSymbolRendererV2.EqualInterval)
 myRenderer.setClassAttribute(myTargetField)

 layer.setRendererV2(myRenderer)
 iface.legendInterface().refreshLayerSymbology(layer)
 layer.triggerRepaint()



 And I want that symbol 1 became a square.
 I can't understand how to use QgsSimpleMarkerSymbolLayerV2.

you can get the symbol layer from QgsSymbolV2 instance:

 mySymbol.symbolLayer(0)

and then change the name for the markersymbol:

 mySymbol.setName(square)

a working example which you can test from python console is:

 layer = iface.activeLayer()
 mySymbol = QgsSymbolV2.defaultSymbol(layer.geometryType())
 mySymbolLayer = mySymbol.symbolLayer(0)
 mySymbolLayer.setName(square)
 layer.rendererV2().symbols()[0].changeSymbolLayer(0, mySymbolLayer)
 iface.legendInterface().refreshLayerSymbology(layer)

 Hi,

 I need to start using the new QEP/RFC setup (today actually), specifically
 for some sponsored work. I don't want the sponsor to think the QGIS project
 is indecisive, so I propose a vote on the naming of the process, since there
 is some disagreement.

 QEP or RFC?

 +0 for QEP (I'm fine with RFC, as well).

 I think RFC is a bit dry, though universally understood. QEP should not
 confuse the public, since the dev group actually interested in using them is
 fairly small. QEP is clearly spelled out in the repo name. QEP shows a
 renewed configuration over the older, existing RFC process.

 Lastly, QEP pays homage to Python's PEP. I think QGIS would not be as
 popular as it is today if it were not for Python integration.

 Now they still show up only if you click to empty area. I have
 excluded it from the ordinary context menu because it is getting
 really long for layers - and expand/collapse all items are not really
 contextual actions anyway. I think we could have a small toolbar like
 in browser dock widget and have those actions there (either directly
 or in advanced menu) - together with actions like new group.

no problem to scroll down a lot of layers to find an empty area :)
but couldn't we think to some submenu action here?
I think it is useful to add they in context menu for groups only as well.


 Also, wouldn't be useful to have a check all and uncheck all actions?

 We already have such thing in Layer menu  Show / Hide All Layers.

yeah, I know, sorry badly explained, I was referring to move them in
the context (sub)menu as well.
Having all in legend should be helpful to the end user imo.

 I did not test the legend refactoring part II branch yet, so I don't

 The second part of legend refactoring contains no changes in this area.

 Hi!

 Currently trying to investigate this ..
 What do you mean with missing?
 A lot of strings changed and that commit was a string update.
 Strings which do not fit any more are marked as unfinished or even
 untranslated after that ..

I refer to strings which have not changed since 2.4 e.g. Python
Console, Road Graph plugin context help.
I suppose that if there are not gui strings changed the translation
string will be kept, or not?


 As italian as a language already switched to transifex it should be
 easy to finish/continue that translations.

 Or do I miss something there?

[Qgis-developer] How about to use a tree widget for plugin manager?

[Salvatore Larosa]

The plugins are becoming more numerous and the number is expected to
grow, it may be useful to include a tree filtered by category, ie
digitizing, vector, raster, geoprocessing plugin, instead of a list
widget.

 Hi,

 I've added generation of the console's API *.pap file for
 auto-completion [0]. This allows to keep up with latest API bindings in an
 easier fashion:

 make  make qsci-pap-src  make install
 Generates the default .pap file (~1 MB) in source tree, which can take
 over a minute.

 make  make qsci-pap-master [ make install]
 Generates a local-only .pap that overrides the default .pap (when
 testing new bindings). It will optionally be installed as well.
 Distributing such an install, like for custom console API completions, will
 always override the default .pap.

 You can edit run the src/python/qsci_apis/generate_console_pap.py
 script directly to produce custom .pap files.

 Please let me know if you can think of a better solution.


 I think this is a good solution, I was going to push the updated APIs
 files generated by myself. Thanks.



 Default .pap includes the following APIs (unchanged from before):

 PyQGIS.api
 Python-2.7.api
 PyQt4-4.7.4.api
 OSGeo_GDAL-OGR-1.9.1.api

 Should GDAL-OGR-1.9.1 be updated to 1.10 for QGIS 2.0 release?


 I would like update to the 1.10.0 version and add the GEOS-3.4.2, I have
 prepared those api files so if there are not objections here I could push
 they to master in order to add the new APIs to the pyqgis.pap file.


 Sounds good to me. I'm done mucking about with the setup, so please make
 the changes you see fit. Looks like the default pyqgis.pap I committed is
 missing the new 'qgis.core.NULL' attribute. Must of missed that somehow.
 Shows up fine when making qsci-pap-master, though. Please test for its
 completion tip in console before uploading another +1 MB .pap file (thanks).


the pyqgis.pap file seems not to have the PyQGIS.api file, I done some
adjustment to the cmake file [0] in order to point the generates_api script
to the right directory. Please could you verify that it is working for you
as well?




 Missing is the QScintilla2 API file, but I think that will just bloat the
 default completions with items most users will not need. IMO, we should
 keep the default .pap as slim as possible, for the same reasons, i.e. just
 core PyQGIS, OSGeo and Python/PyQt modules. That is, until there is
 on-the-fly object inspection support, which would auto-filter the results.


ok, we can leave out the QScintilla APIs, but what about to add the updated
file (QScintilla-2.7.2) into qsci_apis dir ? or should we drop all the old
versions (GDAL-OGR-1.10 will replace GDAL-OGR-1.9.1 and so on) ?

 The point of the qsci-pap-src target is to update the default pyqgis.pap,
 in the source tree. Once that is updated, then the regular CMakelists.txt
 [0] takes care of installing it. This update could be done every once in a
 while, but should always be done right before a release (i.e. like now).
 The target is not part of ALL, otherwise building would take that much
 longer. So, keeping a fairly recent version of pyqgis.pap updated in the
 source tree is a good idea.

 The qsci-pap-master target helps developers when they are testing out new
 bindings and want the console to show them right away. Ideally, once a new
 binding is committed, the qsci-pap-src would be run to update the default
 pyqgis.pap. However, I do not expect this to happen very often; and, it
 seems rather excessive to upload a new pyqgis.pap ( 1MB) so often. It
 should be done a regular basis, though.

 It may be possible to just remove the qsci-pap-master target. But, my
 feeling is that if many developers are updating the default pyqgis.pap, it
 will lead to problems with it.

 In other words, your edits should not be committed. But, you did find a
 bug.  :^)  Indeed, the PyQGIS.api file was not being picked up when making
 qsci-pap-src. I have adjusted the custom commands and the script. GitHub is
 offline right now for maintenance, but I'll commit it ASAP, along with a
 fixed default pyqgis.pap.

 Missing is the QScintilla2 API file, but I think that will just bloat the
 default completions with items most users will not need. IMO, we should
 keep the default .pap as slim as possible, for the same reasons, i.e. just
 core PyQGIS, OSGeo and Python/PyQt modules. That is, until there is
 on-the-fly object inspection support, which would auto-filter the results.


 ok, we can leave out the QScintilla APIs, but what about to add the
 updated file (QScintilla-2.7.2) into qsci_apis dir ? or should we drop all
 the old versions (GDAL-OGR-1.10 will replace GDAL-OGR-1.9.1 and so on) ?


 I think the .api files in QGIS source/install should reflect the 'base and
 most likely' versions available on supported platforms. It is common to
 have a much older QScintilla installed, which is why the older 2.4.5 api is
 in there. Since QGIS is working with much newer OSGeo libs (e.g. gdal-1.10)
 in core, I think it would be better to have more up-to-date .api version
 for those.

 IMO, the idea here is to ensure new users and plugin developers don't get
 used to using a newer API for something that might not be available for all
 users. However, your custom API loader in console should take care of those
 users who do want to use the latest.

 Larry

Re: [Qgis-developer] Console API auto-completion prepared file (.pap)

[Salvatore Larosa]

Hi Larry,

2013/8/31 Larry Shaffer lar...@dakotacarto.com

 Hi Salvatore,

 Sorry to keep messing with this, but it was causing a build error. I
 reverted adding of qsci-pap-master target, leaving it similar to as before,
 excepting the convenience target of qsci-pap-src.

 WITH_QSCIAPI is now marked as advanced, to keep casual users from thinking
 they need to regenerate the .pap file as part of building.

 Here is why I think this is the simplest, most versatile solution:

 *Casual user/dev who compiles/installs QGIS*
 Everything works as before with the default pre-prepared pyqgis.pap in
 source tree used. No generation of .pap occurs. PyQGIS.api is still built
 by default and the target for qsci-pap-src is just created.

 *QGIS dev working on bindings*
 Making qsci-pap-src will update the default .pap in source tree, which
 will be used when running from build directory or install during binding
 testing. If the dev is ready to commit, the already-updated .pap includes
 the latest completions, and everyone benefits. We can use git to revert any
 fouled-up .pap that may make its way into the repo. This assumes the
 committing dev actually ran qsci-pap-src. If not, then any other dev can
 easily do so, updating their source tree, then commit the new default .pap.


this I was not clear in my previous email about the update in the source
tree, but now it does make much sense.

No idea for a better solution at the moment, I agree with your solution.
For now we can go ahead keeping your last commit, just after on Sept 1st.
we can think for a better solution (whether it there is) IMO.


Best Regards,

-SL


 I am really done messing with this now. :^) If you have better solution,
 please let me know.

 Regards,

 Larry

 I'm not sure I understand your question. Doing periodic updates to the
 pyqgis.pap in source keeps from forcing everyone who compiles the source to
 also generate that file. There is no simple means for checking when the API
 has changed (except maybe SHA comparisons of the API file). Without such a
 check, the generation of that file may often be unnecessary, but still done.

 Everyone benefits if that file is kept up to date in the source tree. For
 example, the one I replaced with the initial commit was 11 months old,
 missing many completions for new functions.

 Alternatively, we can set it up similar to what you were suggesting. Let
 me know what you think would be a better solution.

 Regards,

 Larry



 Tonight I'll push the updated API files
 (GDAL/OGR-1.10.0,QScintilla-2.7.2 and GEOS-3.4.2 ) and will add the
 GEOS-3.4.2 APIs to the default .pap file.

 Thanks for the clarification !

Processing--Processing options in SAGA Provider ticks Enable SAGA 2.0.8
compatibility. That should allow you to run SAGA algs.

 This perplexes me. The appropriate path, /usr/local/bin shows in my qgis
 preferences. Sextante was also working at least several months ago in
 trunk. Can anyone provide any suggestions on what may be causing this to
 not work?

 Thanks,

Re: [Qgis-developer] Digitizing behavior

[Salvatore Larosa]

Hi,


2013/8/20 Andreas Neumann a.neum...@carto.net

 Hi Salvatore,

 I think you described it wrong: the former is on the top and not the
 latter. If the latter were at the top it would be more logical and like the
 other GIS.


Yes, I did mean the former is on the top and not the latter.




 I agree that the current QGIS behavior is strange and I wonder why this
 happens. Aren't objects rendered by its order in a table unless there are
 other rules?

 Andreas

 Can you shortly check if this branch would resolve the issue?

 https://github.com/matthias-kuhn/Quantum-GIS/tree/addedontop


the patch solves the problem only on digitizing of the first feature the
next are to the bottom !

 IMHO the render order should be considered arbitrary. The provider doesn't
 return the features in a particular order later anyway.

 Currently (w/o Matthias patch) while the layer is edited feature with
 changed
 geometries are rendered first (ie. bottom), then added features and then
 features from the provider (- those that are going to be deleted).

 I don't think that this must be changed.  If a layer can have overlapping
 features, it probably should be configured to show them transparently
 already.


Yes, you're right and this is a particular case and we can use transparency
if there are overlapping features,
mine was only a reflection on how other software behaved with such a
similar thing.

Nevertheless my vote is for apply Matthias's patch!

 It just might have an impact on other stuff (that false rely on new
 features
 being returned first; maybe in the attribute table, snapping, some user
 plugins).  Not sure if it actually does.

Re: [Qgis-developer] [Qgis-user] WMS of orthophotos delivers strange colours in master

[Salvatore Larosa]

Hi,

2013/8/7 Bernd Vogelgesang bernd.vogelges...@gmx.de

 Thanx Salvatore,

 was too blind too see myself:
 I didn't change anything, just added the url and picked the layer.
 But now i see that in 1.8 PNG was default, while in master, it was default
 to gif!
 I'm pretty sure i never used gif as format for anything, so how come that
 gif there is default?

 Just tested again: when i add the WMS-Service to master, gif is picked as
 default there automatically

 Had a look now at the metadata: image/gif is there mentioned on first
 place of the list of available encodings.
 Maybe master has now a different behaviour on handling these infos than
 1.8?

 gif seems to be a pretty bad choice in any case ... but is that a matter
 of the data provider (changing order in metadata) or of qgis (defaulting
 everything to png when possible)?


I think it depends on how it is in metadata and I am not sure if changing
to defaulting everything to PNG is good.
you could bring this question to qgis developer mailing list [0] in order
to get a more specific answer !


Best regards,

  Hi,

 first i thought that those guys from the saxonian administration were

 When loading the wms in current master, the images look like being
 processed by Andy Warhol.


 I am not sure what kind of brushes were used by Andy W.,
 but are you using the same image encoding for both 1.8 and master ? for
 example PNG ?

 Then i tried it with 1.8., and there everything is ok and as expected.

 I tested on Linux and Windows, both with the same strange look in master.

 Can anyone confirm this? Is it a problem of master, the service or some
 settings?
 Couldn't find any ticket or thread on this so far.

Hi,

I like #185 also, #50 is good but it is too linear IMO I don't know if it
looks fine for other context (splashscreen, web page, desktop icon etc).
Also I think #91 and #88 are misleading for a GIS desktop application.

 Well, I don't like it. First off, I don't get it. At a glance, I have no
 idea what it's trying to convey or why there is so much text.

 Secondly, I think it is imperative for a logo design to offer a
 shortened square aspect, e.g. for an icon. The Q in QGIS obviously lends
 itself to this, and IMO works well for it; so I think a design that
 leverages that single character will be more versatile, than say one that
 only works well for a web site header.

 Hi QGIS devs!

 I'm just been playing with the new python console and it's a great
 improvement -many thanks to Salvatore Larosa.

 One feature that seems to be missing is the ability for auto-completion to
 work on runtime objects using automatic type inference.

 e.g. currently:

  iface.activeLayer().

 does not bring up autocompletion list for the QgsMaplayer object

 Or:

  layer = iface.activeLayer()
  layer.

 does not bring up the autocomplete for the layer object.

 Is this a hard thing to implement? Or is it limited by the Qsci module?

 Cheers,
 Jeremy

Re: [Qgis-developer] Capturing stdout from a plugin

2013/3/15 Gary Sherman gsher...@geoapt.com

 In the 1.x console API, you could use:

 output = sys.stdout.get_and_clean_data()

 to grab what was sent to stdout via print statements.

 Is there an equivalent way to do this with the 2.0 API? I'm not seeing
 it...

currently doesn't exist a similar method in the new console, but all the
print

I had to delete the QgisOutputCatcher class because I got some problem with

However, I think it is better revert that method or add a similar.
I'll try fix it asap.

 On the other hand, I really like the squared corners as I've already
 written in an answer to http://hub.qgis.org/issues/7211.


Ok, I dropped the aquamarine color and I changed something (not much).
Here the new look: http://lrssvt.ns0.it/img/splash_simple_new.png



 Do we keep the discussion here or should we rather move it to the bug
 tracker where it could be recorded together with all evolutionary
 steps of the design?


Yes, you're right, I started the topic for that reason !
I just added there the SVG version so everybody can work on it !

Thanks for your feedback!

Best Regards,

 Best wishes

  could we use that with an old map?

  Thanks for using my idea. I had the same intention, and accidentially
  saw that you used a quiet new (openstreet)map of Essen already in your
  first try ;-)
 
  For your new proposal, I would prefer to see the main text away from the
  interesting parts of the picture, for example more to the bottom.

 Hi Salvatore

 For me it would be a -1 I'm afraid :-(

 We made an informal decision to use old maps and place names (typically
 a previous hack fest venue) for our splashes.

 :-( I was not aware of that decision on splashes,
 anyway I'd like very much see a different splash
 in the new release slightly more elegant and if possible
 with squared borders, keeping the same logic.

 I also issued a new topic in the bug tracker [1],
 so everyone may leave any feedback on it.
 I will put there the SVG version of my proposed.

 BTW, thanks for your replies !

Re: [Qgis-developer] Extract epgs code from input layer

[Salvatore Larosa]

Hi,

2013/2/16 francescobocca...@libero.it francescobocca...@libero.it

 Hi all,
 i would like to extract epsg code from inputvector layer.
 My code is:

 vlayerA = QGisLayers.getObjectFromUri(self.getParameterValue(href.INPUT))
 self.epsg = vlayerA.crs().srsid()

 Is it corrects?
 If i print the values it show strange value.


Those are not strange values, the srs id is the primary key that reference
to SRS in sqlite db.
You should use authid() [1] to get EPSG code or description() [2] to get a
textual description of the SRS.

Regards,
