Re: [Geoserver-users] Gaps in tiled WMS raster layers [SEC=OFFICIAL]

[Richard Duivenvoorde]

Thanks Aaron! 

For letting us know this! I was not aware of this option.

For other wondering what this option does, from:

https://docs.geoserver.org/latest/en/user/configuration/raster_access.html#max-oversampling-factor

"When dealing with reprojection, the underlying raster read operation might do 
some oversampling in order to provide the requested output resolution"

Richard Duivenvoorde

Re: [Geoserver-users] Gaps in tiled WMS raster layers [SEC=OFFICIAL]

[Sedgmen Aaron]

For anyone encountering the same problem, I found the solution was to set the 
max oversampling factor to a lower value than the default.  A value of 3 
provided suitable results for the raster layers and CRSs I'm working with.

>From looking at the GeoTools source code, the default value is 30 in version 
>GeoTools 22.1 (used in GeoServer 2.18.2) and 1 in earlier versions of 
>GeoTools (used in GeoServer versions 2.16.1 to 2.18.1). 

The max oversampling factor is set as a java option in the GeoServer startup 
script (this is covered in the GeoServer user guide), e.g. 
-Dorg.geotools.coverage.max.oversample=3.

Aaron Sedgmen.

Yes, it does look similar.  I tried changing between JAI-EXT and JAI which was 
suggested as a possible source of the problem in GEOS-9016, to no avail.

This is looking like a bug so will log a ticket.

Betreff: Re: [Geoserver-users] No download for ArcSDE Plugin

Hi,
the ArcSDE plugin has dropped out of support, due to lack of a maintainer 
(which in turn happened due to lack of business around the datastore).

In 2.17.x the plugin can still be found among the "community modules", ready to 
be used along with a GeoServer 2.17.x nightly build:
https://build.geoserver.org/geoserver/2.17.x/community-latest/

Same happens for 2.18.x:
https://build.geoserver.org/geoserver/2.18.x/community-latest/

In the upcoming 2.19.0 the store has been completely removed. If you know 
anyone that is willing to maintain the plugin (or is interested
in sponsoring its re-integration in the source code, and the necessary 
maintenance), then it would be possible to bring it back,
the old sources are still in the version control history.

Cheers
Andrea

[Geoserver-users] Layer group not appearing in WMS GetCapabilities

[Joni Hämäläinen]

Hi,

I am struggling, as I can't get a simple layer group to be visible in 
GetCapabilities response for unauthenticated users. 
I am fairly certain there is some issue/bug regarding data security and layer 
groups.

Similar problems have been posted by other users, but I don't see any real 
solutions in the answers:
https://sourceforge.net/p/geoserver/mailman/geoserver-users/thread/CADQ3-ytgSi7mF-ap9fukMWKF_hbKcqAPVYN%2BOWHa_NBm%2BxVOJw%40mail.gmail.com/#msg36625778
https://osgeo-org.atlassian.net/browse/GEOS-9376

Use case is to bundle few cascaded layers to a single group, that would be 
listed for a web app. Listing the layers naturally is done via GetCapabilities.

I have a workspace "example.com", which contains the cascaded store, the layers 
I want to group and the layer group itself.

I can see the layer group in the GetCapabilities when I am logged in to 
Geoserver. But making the same request from unauthenticated browser session 
results in that layer group disappear from the GetCapabilities document. All 
advertised "normal layers" in the same workspace list fine in GetCapabilities 
for both authenticated and unauthenticated users.
Result is the same with either SINGLE/OPAQUE CONTAINER/NAMED TREE setting for 
the layer group. (In the end I would like to set it as OPAQUE CONTAINER).

And note: I can make GetMap requests to the layer group, it works fine as it 
should be! The inconsistency is that it does not appear in the GetCapabilities.

I've come to conclusion that there is some inconsistency with the data security 
settings and layer groups, as eventually I can get the layer group appear in 
the GetCapablities for unauthenticated users. But this requires to relax 
security to level which I'm not comfortable with.

The starting point with security settings, that make the layer group NOT 
visible in the GetCapablities for unauthenticated users (but GetMap works):
*.*.r=ADMIN
*.*.w=GROUP_ADMIN,ADMIN
example.*.r=*
mode=HIDE

I tried adding "example..r=*", no luck.
I tried adding "example..r=*", no luck

Eventually I tried to remove the "ADMIN" requirement for read all, so the 
settings became:
*.*.r=*.
*.*.w=GROUP_ADMIN,ADMIN
example.*.r=*
mode=HIDE

And tada, the layer group appeared to the GetCapabilities document for 
unauthenticated users. 

But naturally I would not like to expose everything readable by default. And I 
am confused, because having the workspace read for everybody works with normal 
layers, as in they appear in GetCapabilities. But a simple layer group in the 
workspace is not included in the GetCapabilities.

I tried to go through the source code and even some test cases, but I couldn't 
find anything relevant to this with my limited knowledge of the code base.

Can anyone confirm, that there is a problem with this regarding layer groups 
appearing in GetCapabilities? Or is this an intended feature?
I feel it pretty strange, that I can happily make a GetMap request to this 
layer group, but it doesn't appear in the Capabilities.

Thank you very much for any feedback on this.

Best regards,
Joni
