Re: [QGIS-Developer] [QGIS-server] Messages: QNetworkDiskCache::prepare() unable to open temporary file

[Giovanni Manghi via QGIS-Developer]

Hi Richard,

the only way I found to have that log message go away is to add manually

[cache]
directory=/path/to/qgis_cache_folder

inside QGIS3.ini wherever your QGIS server installation has created it.

>From the QGIS Server docs it seems to me that setting
"QGIS_SERVER_CACHE_DIRECTORY" in the virtual host should be enough, but it
never worked for me. Maybe I'm not understanding the docs the right way.

Maybe a QGIS Server dev can shed some light here.

This question has been raised few times and really never got a clear
answer, see for example

[QGIS-Developer] Plugin using Pythonnet fails to start during installation

[Lars I. Nielsen via QGIS-Developer]

Hi developers.

We've developed a QGIS plugin, that utilizes Pythonnet to communicate with C# 
on Windows.

Pythonnet is not part of the chosen distribution for Python in QGIS (as of 
3.34), so we do a separate installation of this module into %APPDATA%/Python, 
which is used by all Python distributions on the PC.

But even after Pythonnet has been installed correctly, we get an error when the 
QGIS plugin installer tries to start the plugin.

[cid:image001.png@01DA8A6B.9CAF2A30]

However, the plugin has been installed correctly, and it starts just fine when 
one manually activates it in the plugin window list.


Why can't the plugin start when activated by the QGIS plugin installer ?
Is it running in some kind of restricted environment, that excludes use of the 
APPDATA location ?

Cheers.


Ps!
We are aware of different versions of Pythonnet in Python 3.7 vs 3.9. We 
install both.

Hi Tim.
I am cooked. You made me want to try NixOs now. :)

 Hello everyone,

 Here is the latest report:

- Organize table - toggle selection

- Insert/Edit expression button - display properties

- Relation Reference


 Additionally, I was focused on transitioning from WindowsOS to NixOS.

 Next week, I will continue documenting the 3.36 features. After that is
 finished, I will move on to the 3.38 features.

 Have a nice weekend,
 Selma.
