Re: [Qgis-developer] Spatialite in QGIS master

[Ramon Andinach]

Hi, 

A quick question from user land.

Does having to explicitly set that option mean that spatialite might not be 
supported in the packaged releases of QGIS 3?

As someone that has (mostly) been paying attention to the continued stream of 
"shape files are so old and decrepit" comments that come up on these lists, and 
is making an attempt to learn one of the “modern” storage types (say 
spatialite) I’d like to know before 3 is released if I should be switching to a 
different path.

Re: [Qgis-developer] OTB and LiDAR tools as separate plugins

[Alexander Bruy]

AFAIK, OTB version in OSGeo4W is very outdated (5.0 if I'm not wrong).
Right now latest version is 5.8 and OTB team is working on 5.10.
I think having OTB provider separated from core will allow to update it
faster and also support more OTB features like special parameters types.

I think we are not shipping them. OTB is available in OSGeo4W, but not
in the standalone installers, if I am right

One good thing that we have been discussing, related to this move, is
that for LiDAR tools, it should be possible to have a plugin that has
not just the code of the Processign provider, but the binaries as
well, so installing the plugin would add the algorithms to Processing
without any need to configure the paths to LASTools and FUSION
binaries, since they can be harcoded. If there is a change in the
binaries (such as an update), and the provider code has to be changed,
a new release can be made, independently of the QGIS release cycle
(unlike it happens now)

I think this is an interesting topic to discuss, and that's why I
wanted to send this email to get more feedback.

Thanks for your ideas!

Thanks Victor. I think this is a good improvement, giving OTB and
LASTools more flexibility to update new versions.
One thing that worries me is: we are shipping OTB and LASTools at least
in Windows packages, and I believe we should keep on wit this. So it
seems weird to me an user is now not able to use it straight away, but
he has to install additional software. Maybe we could find a mechanism
to avoid this (install OTB and LasTools plugin in ~/.qgis3 with a
postinstall? this may cause other problems however; (ab)use the new
profiling?)

All the best.

[Qgis-developer] OTB and LiDAR tools as separate plugins

[Victor Olaya]

Hi all,

I have set up the OTB and LiDAR tools Processing provider as separate
plugins, each of them in its own repo. The idea is to have those
providers that require 3rd party apps outside of the core Processing,
so they can be installed separately and managed independently. Alex
Bruy already did that for the TauDEM provider.

The removal of these two providers is in this PR (yet to be merged)

https://github.com/qgis/QGIS/pull/4076

LiDAR Tools and OTB plugins are in repos in my github account at the
moment, but they will be transfered. The OTB dev team has accepted
taking the ownership of the OTB plugin, and Martin Isenburg (creator
of LASTools) will take the ownership of the LiDAR tools one. They will
take care of managing them and making releases when needed

I hope this will help better organizing these pieces of Processing,
and making it clearer for users how to use these providers.

If you have any comment, please let us know.

Thanks!

Re: [Qgis-developer] Spatialite in QGIS master

[matteo]

Hi,

just finish to compile QGIS with Matthias suggestion cmake
-DWITH_PYSPATIALITE

it works now thanks!

However, even with the standard SpatiaLite add button I can load layer,
with DB Manager QGIS crashes saying:

QGIS died on signal 11Could not attach to process.  If your uid matches
the uid of the target
process, check the setting of /proc/sys/kernel/yama/ptrace_scope, or try
again as the root user.  For more details, see /etc/sysctl.d/10-ptrace.conf
ptrace: Operation not permitted.
No thread selected
No stack.
gdb returned 0

Should I open a ticket?

Thanks again guys for the time and help!

Re: [Qgis-developer] Spatialite in QGIS master

[David Marteau]

PySpatialite is a totally obsoleted python package: you must explicitely load 
the mod_spatialite extension using the spatialite load_extension(..).

Qgis use its own version of pyspatialite, but you must enable it in the build 
configuration as stated by Matthias.

Re: [Qgis-developer] Processing ctest for QGIS timeout

[matteo]

I compiled a fresh QGIS master on a virtual machine with ubuntu xenial,
so the machine is super clean (nothing else than the QGIS building
requirements installed)

I still cannot run local ctest for ProcessingQGIS, the terminal just
remains at this line:

4: -- Running /usr/bin/python3
/home/matteo/lavori/QGIS/QGIS/python/plugins/processing/tests/QgisAlgorithmsTest.py

4: Running from build directory!
4: - source directory: /home/matteo/lavori/QGIS/QGIS
4: - output directory of the build:
/home/matteo/lavori/QGIS/build-qgis3/output
4: !!! prefix path was requested, but it is not valid - we do not run
from installed path !!!



as Matthias suggested I also ran the test with gdb [0] to see where the
code gets stuck and it seems that there is a segmentation fault. Here
the pastebin [1] of the complete output.

gdb ends:

Thread 1 "python3" received signal SIGSEGV, Segmentation fault.

Thanks to all that can help on this!

[Qgis-developer] Spatialite in QGIS master

[matteo]

Hi all,

I don't know if a miss some older discussion on this topic but I'm not
able to load SpatiaLite databases in QGIS 3.

It seems there there is no pyspatialite for python3:

Traceback (most recent call last):
  File
"/home/matteo/lavori/QGIS/build-qgis3/output/python/qgis/utils.py", line
598, in spatialite_connect
from pyspatialite import dbapi2
  File

647, in _import
mod = _builtin_import(name, globals, locals, fromlist, level)
ImportError: No module named 'pyspatialite'


I checked around on the web and I found an issue the github repo [0]

Has anyone a working SpatiaLite db on QGIS?

Thanks to all

Matteo
