[Qgis-user] Couldn't load SIP, Python support disabled

[Ahmed Shubbar]

I recently installed Qgis on Fedora 30. But did not get python support
working and can see only 8 plugins available. I also tried installing newer
Qgis 3.6.3-Noosa, but got the same errors.

QGIS version: 3.4.6
OS: Fedora 30


### Python Error 1:

Re: [QGIS-it-user] [OSGeo4W] errore di installazione

[nformica]

Ciao Stefano,

ad alcuni amici che hanno provato ad installare QGIS 3.4 su Windows 10 con
Osgeo4w 64 bit, si è ripresentato esattamente questo problema da te
riportato qualche tempo fa.

Hanno chiesto il mio aiuto, ma non sono riuscito a risolverglielo.
Credevo fosse un bug ormai scomparso e invece a quanto pare no!
Tra l'altro non succede sempre con tutti i Windows  non capisco da cosa
può dipendere.

Avete qualche consiglio ?

Saluti
Nino Formica

Was reported at https://github.com/qgis/QGIS/issues/29885

What is annoying is that I fixed that issue 2 years ago per
https://github.com/qgis/QGIS/pull/3034.
I can't see what has changed on GDAL or QGIS side regarding how and when files 
are opened in read-only vs read-write mode since then. So perhaps this would 
be related to a change on MapInfo side how it opens files in newer versions.

Re: [Qgis-user] Version 3.4.7 (LTR) is locking MapInfo tab files

[Bo Victor Thomsen]

The original bug: https://github.com/qgis/QGIS/issues/29885

The original fix: https://github.com/qgis/QGIS/pull/3034

Excerpt from the bugfix:


 *rouault  * commented on 27 Apr 2016
 


 "Additional precision for completness. The name of the PR is maybe
 a bit misleading. It should read "concurrent opening".
 Modification in MapInfo while a dataset is opened by QGIS is not
 possible. But this was already the case with GDAL 1.X. But
 modification in QGIS is possible and MapInfo will see the changes.
 MapInfo apparently needs an exclusive access to the files to allow
 saving them. Fixing that isn't in the immediate scope of interest
 and would require both changes in GDAL and QGIS so that QGIS asks
 GDAL to close file descriptors when it doesn't need access to the
 files."

As I read this excerpt, it means that it's not possible for MapInfo to 
update a tab-file while an instance QGIS is using it whether it's for 
update or for read purposes.


I don't know if there is other bugfixes that has addressed this issue.

I've been in the same situation a while back with an organisation having 
2000 - 3000 tab files. My solution was to put all data from the tab 
files into a Postgres database and create tab files that "pointed" to 
the new tables, and let both MapInfo and QGIS users use the Postgres 
tables in stead. This was a long and exhausting process but it - for 
once and all - solved the concurrency problems.


It not the mechanical process to convert the tab-file to a table that is 
the problem. That is a task that can be solved using ex. ogr2ogr. The 
worst problem is deciding which version of each and every tab file that 
is the most current and complete and choosing this tab file for 
conversion to postgres.

Sorry,
my example was bad
QGIS_AUTH_PASSWORD_FILE already points to a full path to the text file 
containing the password

but FcgidInitialEnv vars are not mentioned by QGIS Server log
Instead it shows
Auth DB PATH: //.local/share/QGIS/QGIS3/profiles/default/qgis-auth.db

[Qgis-user] Version 3.4.7 (LTR) is locking MapInfo tab files

[Paul Wittle]

Hi,

I believe there may already be a bug ticket for this but I've found my 
deployment of QGIS is causing MapInfo errors when opening MapInfo tab files. It 
happens when you load the TAB file and also when you open the project and it 
even happens when a TAB file is open but not rendering.

This is a pretty major issue for people that are looking at a migration as we 
are so we need to get this one fixed asap. Does anyone know if there is a fix 
being worked on or is funding required to get this one fixed asap?

Hi Philip.

I’m a developer, but not a very proficient user of QGIS yet, so 
scripting sounds like music to my ears J


Is scripting inside QGIS without plugins even possible ? The example 
focuses on the script itself, not how to perform the scripting.


Or are you talking about scripting outside QGIS in a regular Python IDE ?

Hi Lars,

Should be possible to script with pyQGIS?

Example of how to add and update attributes here:

Hi Bo.

Yes, I did have a try with the Processing Modeler, but I failed to 
locate any function to update attributes.


It seems like it’s only purpose is to generate a new (temp) layer ?

Hi Lars -

Have you tried to take a look at the processing framework ? It works 
appr. like the FME Desktop, but inside QGIS.

*https://docs.qgis.org/testing/en/docs/user_manual/processing/index.html*

If you simply want to change / edit the attribute-values of multiple 
records from a layer in one operation, then have a look at:

*https://docs.qgis.org/testing/en/docs/user_manual/working_with_vector/attribute_table.html#editing-multiple-fields*

Re: [Qgis-user] Auxiliary storage: not editable if layer is not editable

[Bernhard Ströbl]

Hi Paul,

thanks for your feedback. I figured out that the label-positioning 
buttons do indeed work but I was after setting an x-y offset for a point 
symbol.

I created a ticket meanwhile:
https://github.com/qgis/QGIS/issues/30376

Indeed you're right.

Actually you just have to use the "Move Label" map tool directly on 
labels, and their positions will be stored in auxiliary storage 
automatically. If you want to manually create corresponding fields, you 
have to use the "Store Data in the project" button in data defined menu.

Hi all,
I have a PostGIS relation that is not editable in QGIS (user has only

positioning information. I cannot edit this field because "toggle

Anything I

BTW I am using QGIS 3.4.8.

Re: [Qgis-user] Plugin to perform repetetive update ?

[Bo Victor Thomsen]

Hi Lars -

It's actually easy - you can ex. use the *python console *(Ctrl-Alt-P). 
It will get you a console window like this:*

*

The rightmost window is a nifty little python editor with syntax 
highlighting and autocompletion. It is activated by clicking the third 
button (from the left) in the console window.


It's like the MapBasic window in MapInfo on steroids.

Take a look at: 
https://www.qgistutorials.com/en/docs/3/getting_started_with_pyqgis.html 
for getting you started.

Is scripting inside QGIS without plugins even possible ? The example

Or are you talking about scripting outside QGIS in a regular Python IDE ?

Re: [Qgis-user] Table manager

[Etienne Trimaille]

Indeed Table Manager was already deprecated for some functions in QGIS 2
IIRC.

But it depends what you wanted to do with TableManager. If you simply
wanted to rename fields, you can go in the vector layer properties,
"fields" tab and rename columns there. No need to use the "refactor fields"
algorithms, which will regenerate a new layer.
