[mapguide-internals] GDAL Provider update

[Trevor Wekel]

Hmm...  Now this is interesting.

I was digging around the GDAL project website and found a link to some updated GDAL 1.6 binaries.  These binaries are compiled with Visual Studio 2008.  They also include ECW and SID libraries compiled with Visual Studio 2008.

I used the 32 bit GDAL 1.6 binaries from http://vbkto.dyndns.org/sdk/release-1500-gdal-1-6-mapserver-5-6.zip and dumped them on my Windows 2008 R2 64 bit test machine.  They also have 64 bit binaries posted.

The consistent dll set seems to make a "slight" difference.  SID, ECW, and JPEG2000 seem to be working with a single user hitting them.  I haven't tried a multi-user scenario yet.

Here's the dlls I copied over:

Server\bin\libecwj2.dll
Server\bin\lti_dsdk_dll.dll
Server\bin\gdalplugins\gdal_ECW_JP2ECW.dll
Server\bin\gdalplugins\gdal_MrSID.dll
Server\Fdo\gdal16.dll
Server\Fdo\geos_c.dll
Server\Fdo\iconv.dll
Server\Fdo\libcurl.dll
Server\Fdo\libexpat.dll
Server\Fdo\libpq.dll
Server\Fdo\libtiff.dll
Server\Fdo\proj.dll
Server\Fdo\spatialite.dll
Server\Fdo\xerces-c_2_8.dll
Server\Fdo\zlib1.dll



Regards,
Trevor

No kidding :)

Did you see the patches attached to this ticket?
http://trac.osgeo.org/mapguide/ticket/462

<http://trac.osgeo.org/mapguide/attachment/ticket/462/grfp_addref.patch>Traian
found and created a patch for a reference counting issue in the provider,
but I don't think it's ever been applied (I think fixing it at the time may
have caused a problem?)

Also, I'm still not convinced that not guarding the stylization (re
mapguide_raster_stability.patch from Haris) call isn't risky.  I didn't
really understand the arguments one way or the other, but it sounded like
this was trading potential stability for performance.  I think this would be
around here now:

http://trac.osgeo.org/mapguide/browser/trunk/MgDev/Server/src/Services/Mapping/MappingUtil.cpp#L718

For the record, I've had success on Windows Server 2003, 32bit, MapGuide
2.1.  Haven't tested anything newer, or x64.
