Re: [Qgis-user] Win7 with Roaming App Data and Profile Redirection - [ERROR] Can not make qgis.db private copy

[Hillers Heather]

I started QGIS 3 in a working environment as a new user and then copied the 
whole profile directory.  You do have to go through the settings first, 
particularly for Processing, and for Network and remove any paths that are 
specific to your user.  And if the user has already had the problem then you 
have to completely log them out of the system.  But then it should work.  In 
our case the directories themselves seemed to have the lock on them.  The error 
is about qgis.db but when we look at the profile, the whole profile directory 
is missing but secretly still there.  So just copying a particular file 
wouldn’t work.

Hi Heather,

Thanks for your response! In my situation, I'm getting this error for 100% of 
users with redirected app data rather than just some, but I am interested in 
your workaround.

Could you help me understand which files/folders you're copying from a known 
good/working profile to a problematic one? I can test in our environment and 
let you know if that resolves the issue for us.

Thanks again,

Re: [Qgis-user] Unable to launch QGIS with X Forwarding - Can Not make

[Hillers Heather]

I am having the same qgis.db error using a Windows Farm environment with 
profiles stored on a network drive.  It appears to be a problem with the delay 
in synchronizing the directory with the server 

After getting this error and closing QGIS 3, we find ourselves in the following 
situation

1. We open msys.
2. We cd to the parent of the profiles directory.
3. We ls. profiles does not exist.
4. We mkdir foo.  That is successful.  So we have permissions.
5. We cannot mkdir profiles.  That is an error from the file system, because it 
thinks profiles exists already.
6. We cannot remove profiles, because the system thinks it is in use by another 
program.

Restarting QGIS doesn't work.  The only solution we have found is to completely 
log the user out of the system, log back in, copy a dummy profile to the 
profile location, and start QGIS 3.

This is happening to 1 out of 4 new users on our system, as we move them from 
QGIS 2 to QGIS 3.  (QGIS 2 never had this problem.)  

Since we have 50 users, we are going to each user and doing their first startup 
and settings personally, using the dummy profile.  This isn't so bad, since it 
helps make sure the user's environment is just as they want it, but I would be 
happier if the profile problem wasn't there.

Hi everybody,
I have a ubuntu Bionic LTS server with QGIS 3.4 LTR installed
Since the Qgis project I've published connects to local postggis data I
would like to launch Qgis with X forwarding to modify directly the
published project...

The client is debian 9.8 when I try to launch qgis it shows me the import
esttings window, then the splash screen and after that an alert window with
message "ERROR Can Not make qgis.db private copy" the stdout also log the
following

ERROR: auth db directory path could not be created
ERROR: opening of authentication db FAILED

the auth db path is setted in apache. conf for qgis server: tried to set
the same path as environment variable but no change.

seems that after installation I don't have .qgis3 folder

Any suggestion?

Amedeo

There's no .qgis3 anymore - the user profiles are in

Re: [Qgis-user] Corporate Users

[Hillers Heather]

Hello,

I am administering a QGis LTR 2.14 installation for 50 users on a Citrix 
Windows 7 networked environment using OSGeo4W, using OSGeo4W and Oracle as our 
database.  We have been productive since Qgis 2.8.  We started testing at Qgis 
1.8.  My users press All The Buttons, so I feel like I've run into just about 
every problem there is.  I feel like we have a stable productive system.   I'd 
recommend looking at QGIS Enterprise from Sourcepole for support and ease of 
installation.  We didn't go that direction, but I'm still keeping an eye on 
them, and they might be the right solution for you.  Boundless also delivers an 
enterprise solution.  If you have questions about my experience with the 
system,  you can send me an email.

Regards,

Heather Hillers

[Qgis-user] LTR Upgrade 2.8 to 2.14

[Hillers Heather]

Hi,

I'm getting ready to move my (50) users from 2.8 to 2.14 on the qgis-ltr 
branch.  Would you recommend starting them on a fresh Profile directory (which 
would mean going to each user and re-doing their Settings for them) or is it 
safe to let them keep the Profile directories they had for 2.8, which would 
preserve their Settings with the new version?

Has there been any problems with 2.8 projects that are opened, edited and saved 
in 2.14?

Thanks,

Heather

[Qgis-user] Another Raster Problem

[Hillers Heather]

Hi,

I have a set of tifs that cause an AppCrash on load to 2.14.6 and 2.16, either 
immediately on load or shortly after.  I can load and work with these files 
without problem in QGIS 2.8.6

I have produced 4 small hillshade tifs, each less than 1000 Kb in size. Each 
has a world file and a kml in the same directory.  I have uploaded them to 
https://github.com/HeatherHillers/QGISRasterLoadCrash

We have a networked Windows 7 32bit environment running OSGeo4W (qgis-ltr) as 
well as a local Windows 7 32 bit environment running OSGeo4W (qgis-ltr and 
qgis)  and the problem shows in all 3 installations.  The QGIS 2.8 that loads 
the files successfully is also running on a networked Windows 32bit 
environment.  Storing the files on a networked vs. local drive doesn't seem to 
impact the problem.

The CRS of the files is 32619.  I have tried eliminating Reprojection in my 
settings and in the project settings.

I have produced the data by following the instructions in the following 3 
(excellent!) tutorials from LASTools, using their test data.  I didn't get any 
errors in generation, and the tiles look very nice in 2.8, so I don't .think. 
they are corrupt.

[Qgis-user] QGIS Plugin Repositories not available?

[Hillers Heather]

The last few days we have lost the ability to load the QGIS Plugin Repositories 
at 
https://plugins.qgis.org/plugins/plugins.xml?qgis=2.14

The same is happening for versions 2.8 and 2.16.  Their Status is unavailable.  
We haven't changed our system (that I am aware of) and we can load WMS Services 
fine.  The problem comes with both Default Proxy and Http Proxy.  Is there 
something going on with the system or the paths or is it just us?

[Qgis-user] Geoprocessing Tools give wierd answerd

[Hillers Heather]

Hi,

I have a Multiline layer A with about 900 Features loaded (only a few of those 
are actually multi part geometries)  in QGIS 2.14 and I try to do Vector  -> 
Geoprocessing Tools -> Difference with Layer A as the input vector layer and 
Layer A as the difference layer, expecting to get as a result an empty layer.  
But, the Output Shapefile has ~150 Features in it.  Topology Checker says, 
there are no invalid geometries, but there are about 90 pseudo nodes in the 
layer.  I started snooping around and found other line shapes that behave this 
way.  Have I fundamentally misunderstood what a difference is, or is there some 
specific geometry problem that causes difference to behave oddly?  The use case 
is silly, but I started with comparing an exported shape to its source, got 
weird results, and then tried to compare the source to itself as a sanity 
check.  Now I feel I might have lost sanity.  Help?

Thanks,

[Qgis-user] Oracle connection timeout returns

[Hillers Heather]

Since 2.8.1, Jürgen Fischer repaired an oracle timeout connection error with the
qoci spatial driver: cleanup session  connection when login 
failedhttps://github.com/qgis/QGIS/commit/4789c2361dd5d3e336838492af757f10310d0531

This patch first appeared productively in 2.8.2.

We find that on our local Windows machines and on one of our test Windows Farm 
machines, this patch works.  However, on our productive Windows Farm machines, 
we are still getting the error.   We think this is either because the load on 
the Windows Farm machines is much higher than the load on our local and test 
machines, or there is something up with the client on the windows farm 
machines.  However, since qgis comes with its own oracle client, it's really 
hard to tell what is going on.  We know there should be no difference between 
our Test Farm machine and our productive Farm machines.  That indicates to us 
that it is just the load that makes the difference.

So, a couple questions:


1.   Is it possible there is a lingering oracle timeout error in qgis? 
Something that doesn't show up in low load situations?

2.   Is it possible to use the system oracle client with qgis instead of 
the internal client?

3.   How does qgis and it's internal oracle client work?

Thanks,

Heather

[Qgis-user] QGIS-rel-dev doesn't install alone

[Hillers Heather]

We really need qgis 2.8.2 on our productive system to fix an oracle bug that is 
for us critical and becoming more and more critical as we get more users.  We 
were waiting for the point release to come, but this week we decided it was 
better not to wait and just install the qgis-rel-dev as our production version 
until the point release came.  However, when we run OSGeo4W and try to 
uninstall the qgis module and install the qgis-rel-dev module, it doesn't work. 
 We end up with qgis and qgis-rel-dev anyway, and 2 start menu items.

We get the dependency notice, qgis required by qgis-globe-plugin, 
qgis-grass-plugin, qgis-oracle-provider.  We definitely need qgis-grass-plugin 
and qgis-oracle-provider.  How can we get a clean install of qgis-rel-dev?

[Qgis-user] Oracle connection Timeout

[Hillers Heather]

We have a QGIS installation running with a Oracle 12 Database.
If we open the Qgis Oracle Connection window and set up a connection without 
saving our username and password, then click on the connect button, and then 
add any table to qgis, our DBA gets the error below:

We are experiencing the same problem whether we are connecting from our QGIS 
2.2 installation on Linux or our QGIS 2.6 installation on Windows. We 
experience the same problem with 2 different databases, and with 2 different 
oracle servers.  We have tried increasing the connection timeout on the oracle 
side to 200 seconds, with no effect.  From qgis, we see no hang or connection 
problems.  We are quickly asked for our credentials and the layer loads 
successfully.  The error usually comes after the load is complete.  These 
errors also come with the opening of projects with Oracle tables in them.  The 
end result is that we have to do a daily reboot of our TNS Listener.  Our DBA 
finds this unacceptable, particularly since the number of users is expected to 
rise sharply.  I am not seeing any reports of other users with this problem.  
Any ideas?

Thanks,

Heather

[Qgis-user] Qgis settings corrupted after crash.

[Hillers Heather]

Hello,

We have QGIS 2.6 running on a Windows Farm environment.  We are currently 
testing the installation with a few users to judge stability.  We have twice 
seen the following:

1.   Qgis crashes or ends badly for some reason.

2.   Qgis is restarted by the user.

3.   The user sees the settings from another user. (network settings, 
database connections, last used projects, everything)

We cannot reproduce this error.  We can only confirm that on 2 separate 
occasions in the last 2 months, 2 separate users have seen the error in the 
presence of reliable witnesses, and that on one occasion it happened in a 
workshop in which the 2 affected users, of which I was one, were sitting next 
to each other and could view each other's screens.

Our user profiles are on a networked drive K:\qgis, so that we have the same 
QGIS profile everywhere in the farm.  One upshot of this is that from the 
Windows machine it is not possible to see the profile of another user.  How one 
user's QGIS instance is reading another user's profile is a mystery.  Our 
theory is, that when QGIS crashes, perhaps it tries to restore its state from 
some  ... place, that is central, and not separate to the user, or they are in 
memory somewhere.  And maybe in that way it somehow grabs the in memory or in 
cache settings from the most recent active user in order to restore the state?

Does anyone have an idea what this problem might be, what kind of diagnostic I 
could run, where I could look for clues?  This is clearly going to be really 
bad if it happens often with all our users on the system.  I need a fix badly.

Thanks,

[Qgis-user] Issue installing compiled QGIS release_2-2

[Hillers Heather]

Hello,

I am having troubles with the results of make install for QGIS branch 
release_2-2.

I have on Ubuntu Precise a production Qgis 2.2 from Ubuntugis-unstable 
packages.  I want to test Qgis 2.2 with Oracle support in a second installation 
on the same machine.

Following the instructions in INSTALL, I compiled 2.2 and ran make install to 
prefix /usr/local. This Qgis ran, but did not have PYQGIS support.

I got the error below at program load.

When I run from build/output/bin/qgis, the program works without error.  I 
tried installing to /usr/local/qgisdev, and to $HOME/qgisdev, with the same 
error result.

The install is also failing to load the grass plugin, which also has no 
problems in the build dir.

I don't see anything where my production distribution is clobbering.  Any 
suggestions would be extremely appreciated (including a hey, but you can get 
an Ubuntu Precise Qgis 2.2 with Oracle support package from here and you don't 
really have to compile it suggestion)

Thanks, Thanks, Thanks,

Heather

[Qgis-user] Centos Raster Anomalies

[Hillers Heather]

Hello,

I have built qgis 1.8 final release from source  on Centos6.  When I run make 
check, I get failures in qgis_rasterlayertest and qgis_rendererstest.  These 
failures are the result of raster anomalies that do not match the expected 
raster anomalies stored in testdata.  Attached are the raster anomalies, which 
in many cases are similar too (but a bit worse than) the expected windows 
anomalies.  The anomalies are as follows:

Continuous_result_diff.png
Graduated_result_diff.png
Landsat_875_result_diff.png
Landsat_basic_result_diff.png
Raster_pseudo_result_diff.png
Raster_result_diff.png
Single_result_diff.png
Uniquevalue_result_diff.png

I added these raster anomalies to tests/testdata/control_images/[test case], 
and that did eliminate the unittest failures as a result of anomalies not 
matching any expected anomalies.  However, my unittests still fail after the 
anomaly match as a result of bandStatistics

   Loc: 
[/pse/edv/hil/src/qgis/18release/qgis-1.8.0/tests/src/core/testqgsrasterlayer.cpp(177)]

When I ran qgis_rasterlayertest through gdb,  this mean value was found to be 4.

Qgis is linking yum installed libpng 1.2.49.


1.   Are the anomalies a feature of the system, and just need to be added 
to testdata, or are they manifestations of a bug?

2.   What can I do about the bandStatistics error? Is this going to cause 
bad behavior in qgis, or is only going to effect image quality?

3.   Might this be coming from a library dependency?


Thanks,

MonsterMushroom
