Re: [QGIS-Developer] Issue with QGIS 3.16.2 standalone and GRASS 7.8.4

[Myriam63]

Hello to all
Last version (3.16.3) successfully installed!
The problem in 3.16.1 and 3.16.2 versions are no longer present and no new
issues identified.
I hope it stays that way! ;)

Re: [QGIS-Developer] QGIS composer print layout

[JD L]

Hi Giulio,

add the flags methods to tell your algorithm is not thread-safe. From the
documentation :
https://docs.qgis.org/3.16/en/docs/user_manual/processing/scripts.html#flags

If your algorithm is regularly crashing, you are probably using API calls
which are not safe to do in a background thread. Try returning the
*QgsProcessingAlgorithm.FlagNoThreading
flag from your algorithm’s flags() method* to force Processing to run your
algorithm in the main thread instead.

I just tested and it works.

Regards,

By default qgis server is built with SERVER_SKIP_ECW TRUE for debian/ubuntu and
in osgeo4w.

[QGIS-Developer] GDAL Version Mismatch - Compiled vs Running

[i-s-o]

For the Nightly-Master, I just noticed the following. Is this the expected
behavior?
Compiled against GDAL/OGR 3.1.4
Running against GDAL/OGR 3.3.0dev

I am pretty sure it used to be the same as the current Nightly-Release:
Compiled against GDAL/OGR 3.3.0dev
Running against GDAL/OGR 3.3.0dev

Re: [QGIS-Developer] ECW flags

[Vincent Picavet (ml)]

Hi Walter,

Be careful with ECW SDK licence, which requires an OEM licence for any use in a
Server software component.

See for example :
https://community.hexagongeospatial.com/t5/APOLLO-ECW-Q-A/License-for-reading-or-writing-ECW-in-third-party-software/ta-p/34074#

This may have changed since 2019, but I doubt it.

In any case, I would rather recommend using an alternate format, with free and
opensource format and drivers.

Best regards,
Vincent

[QGIS-Developer] Nightly LTR for 3.16.4 Release Candidate

[Alexandre Neto]

Hi,

Carrying on the work of QEP-180[1], we are now "metatesting" the testing
infraestructure and metodology[2] by running the set of designated test
cases  (manual tests) for the next releases 3.18.0 and 3.16.4LTR.

For the later, we would need to have the nigthly-ltr builds pointing to the
release 3.16 branch.

Question: Normally, when does the switch from the old LTR moves to the next
one happens? I was hoping that it would happen before the release itself.

Re: [QGIS-Developer] ECW flags

[Walter Lorenzetti]

Hi Vincent,

I've to do it for a customer who bought OEM licence from Erdas.

Every time I try to push my customers toward free formats, sometimes I 
can, other times not :)


Have a good Sunday
