[Geoserver-users] Is KML support broken in 1.7.0

Amr_A_Alam · August 21, 2008, 4:54pm

I'm trying to view some layer on Google Earth, and am getting this error on Geoserver 1.7.0 running under tomcat...

This is happening for one of the default layers:
http://localhost:8080/geoserver1.7.0/wms?service=WMS&request=GetMap&format=application/vnd.google-earth.kmz+xml&width=1024&height=1024&srs=EPSG:4326&layers=topp:states&styles=population&KMScore=50&KMAttr=true&legend=false

Sending the same request to the 1.6.1 version works just fine:
http://localhost:8080/geoserver1.6.1/wms?service=WMS&request=GetMap&format=application/vnd.google-earth.kmz+xml&width=1024&height=1024&srs=EPSG:4326&layers=topp:states&styles=population&KMScore=50&KMAttr=true&legend=false

Any ideas about what's going on? BTW, this is the case with any layer, even when using the KML link from the map preview page.

Here's the exception I'm getting in the logs for 1.7.0:

Confirmed.

It appears that the recent code to remove the need for GetMapProducerFactory (GEOS-654) instances has introduced a problem. It is doing a strict match against the name of an output format. Where as the kml stuff requires a check like:

(mapFormat.startsWith(PRODUCE_TYPE) // "KMZ"
&& mapFormat.startsWith("application/vnd.google-earth.kmz"));

Due to the "+" in the output format name. This is a pretty serious regression, i am re-openning GEOS-654.

Thanks for the catch Amr!

Agreed, we don't want regressions...
Yet, I wonder about one thing.
The old KMZMapProducerFactory stated the official mime type had no "+xml" at
the end:
/**
* Official KMZ mime type
*/
static final String MIME_TYPE = "application/vnd.google-earth.kmz";

And that's why I didn't include an alias for the map producer as did for other
formats like SVG, or "rss", "application/rss xml", application/rss+xml.

I can easily add an alias for "kml" or whatever, but do we actually want the
output formats in a request to be "whatever starts with..." It doesn't seem
quite right to me. I mean, the output formats are meant to be the ones stated
in the capabilities document, not whatever starts with a given string...

That's almost it, I didn't allowed that because that was not supposed to
happen in my understanding. Yet I see now there's actually a missing alias in
order to use just "kmz". Just that before kmz where not stated in the
capabilities neither...

I propose to use the aliases as stick to what we state we support in the
capabilities. Thoughts?

Cheers,

Gabriel

I think aliases are a really good thing. I also noticed that the 'openlayers' alias went away. I think we should have that in there. When you're using the WMS reflector in particular you don't want to have to remember exactly the vnd.google-earth thing.

I think we should only say that the aliases are shortcuts, that they should not be used programmatically. But I don't think we should just support how things are reported in the caps document, since it's strict about it having to be the mime-type, which can have weird definitions. But I say we should have lots of aliases - isn't there some quote about being lax on what you accept and strict on what you return? Or maybe I'm getting it completely backwards.

Hey, thanks for the feedback.

You're right, here I made a mistake: output formats stated in getcaps shall be
MIME types so its not that right if we include the aliases as output formats.

So what if we do this: lets the GetMapProducer have only a getContentType()
method, returning the MIME type it produces, so that's the one stated in the
caps.
By the other side, replace getOutputFormat():String, which is being used as
the value of a getcaps outputformat, by a
getContentTypeAliases():List<String> and a setter so the aliases can easily
be set by setter injection in applicationContext.xml like this:

  <bean id="KMLMapProducer"
    singleton="false"
    class="org.vfny.geoserver.wms.responses.map.kml.KMLMapProducer">
    <property name="contentTypeAliases">
      <list>
        <value>kml</value>
        <value>application/kml</value>
        <value>etc...</value>
      </list>
    </property>
  </bean>

Then we can at least be strict about the formats we state in getcaps and still
write down a comment telling what aliases we support.

GetCaps being MIME types brings also an old concern that image/png8 is wrong,
and we should state instead something like "image/png;colordepth=24"
and "image/png;colordepth=16" or just "image/png"
and "image/png;colordepth=16". That's the way I guess exrta parameters are
set for a MIME type, but I still need to check the RFC to see exactly what
the rules are.

BTW, KMLReflector is sending "format=application/vnd.google-earth.kml+XML"
and "format=application/vnd.google-earth.kmz+XML". Note the upper case XML
suffix. Can I let just a single constant for the mime type and remove the
various definitions? (there are a couple repeated constants and a couple
hardcoded values)

Cheers,

Gabriel

When you're using the WMS reflector in particular you don't want to have
to remember exactly the vnd.google-earth thing.

I think we should only say that the aliases are shortcuts, that they
should not be used programmatically. But I don't think we should just
support how things are reported in the caps document, since it's strict
about it having to be the mime-type, which can have weird definitions.
But I say we should have lots of aliases - isn't there some quote about
being lax on what you accept and strict on what you return? Or maybe
I'm getting it completely backwards.

I agree, the code matching the kmz mime type is loose... but i believe it was put in place because the "+" gets transformed to a space in get requests... so straight string matching failed.

Anyways, I am all for aliases to make it simpler, but we still have to support the full mime type for backwards compatibility.

It appears that the recent code to remove the need for
GetMapProducerFactory (GEOS-654) instances has introduced a problem. It
is doing a strict match against the name of an output format. Where as
the kml stuff requires a check like:

(mapFormat.startsWith(PRODUCE_TYPE) // "KMZ"
&& mapFormat.startsWith("application/vnd.google-earth.kmz"));

Due to the "+" in the output format name. This is a pretty serious
regression, i am re-openning GEOS-654.

Agreed, we don't want regressions...
Yet, I wonder about one thing.
The old KMZMapProducerFactory stated the official mime type had no "+xml" at the end:
/**
  * Official KMZ mime type
  */
static final String MIME_TYPE = "application/vnd.google-earth.kmz";

And that's why I didn't include an alias for the map producer as did for other formats like SVG, or "rss", "application/rss xml", application/rss+xml.

I can easily add an alias for "kml" or whatever, but do we actually want the output formats in a request to be "whatever starts with..." It doesn't seem quite right to me. I mean, the output formats are meant to be the ones stated in the capabilities document, not whatever starts with a given string...

That's almost it, I didn't allowed that because that was not supposed to happen in my understanding. Yet I see now there's actually a missing alias in order to use just "kmz". Just that before kmz where not stated in the capabilities neither...

I propose to use the aliases as stick to what we state we support in the capabilities. Thoughts?

Cheers,

Gabriel

Thanks for the catch Amr!
