Hi,
I made a short test with 2.7-beta and found that validation does not actually
work just as planned from the UI.
- I changed coverage name “Img_Sample” into “Img Sample” from the UI.
Observe that it is possible.
- Checked how the layer/coverage name is advertised in some services:
WMS 1.3.0 <Name>nurc:Img Sample</Name>
WCS 1.1.1 <wcs:Identifier>Img Sample</wcs:Identifier>
WCS 2.0.1 <wcs:CoverageId>nurc__Img Sample</wcs:CoverageId>
- The others are OK but I suppose that WCS 2.0.1 is not because the
spec mandates that coverageID is NCName and space is not allowed if I
understand NCName right. Name would be wrong also as WFS FeatureType name for
all versions.
- Tried to change “Img Sample” back to something acceptable but it is
not possible from UI. Error is:
“Validation failed with 1 errors. First error message is: Name 'Img Sample' is
not legal XML'”.
Validation seems to happen in a bit wrong place. First change into invalid name
was OK because the original name was acceptable. Second edit fails because the
existing name, which is wrong in this state, is checked. I had to edit XML
files in data_dir manually before UI could cope with this layer again.
We have a trouble because the default layer name or the edited name from the
Basic Resource Info is automatically used in all services. WCS 2.0.1 makes a
difference because it tries to build a valid NCName by removing colon and nurc:
is changes into nurc__. However, it does not analyze the base name of the layer
and not-allowed space is accepted.
Automatic validation and denial is probably too strong operation, but as a user
I would appreciate some kind of warnings:
WARNING: '137105_CSKS3_DGM_B_HR_01_VV_RA_FF_20141017035343_20141017035413' is
not legal name for the following services:
WFS (all versions)
WARNING: 'Img Sample' is not legal name for the following services:
WFS (all versions)
WCS 2.x
WARNING: ‘Img Sample’ name contains characters which can lead to failure with
some client programss:
White space,[list other characters].
Perhaps we will need a lookup table that allows fine grained control of
advertised layer names in different services and versions.

Aihe: Re: [Geoserver-devel] Regression in 2.7.x, valid coverage names are
rejected because not valid xml names
Ah hem, errata corrige, the commit in question was also silently backported to
2.6.x,
so we have the same regression on the stable series...
Cheers

For the record, found the pull, not the discussion:
https://github.com/geoserver/geoserver/pull/786
Found the discussion too:
http://osgeo-org.1560.x6.nabble.com/Layer-and-store-names-td5167890.html
I did agree back then... and I was wrong, probably was thinking just of
invalid feature type names.
Reading though the discussion, we all agreed about some sort of validation, but
it did not have
xml safe one.
What about using the xml safe pattern for feature types, and something more
relaxed for
everything else, like no spaces, and/or valid file name, or something of the
sort?
Cheers
Andrea
