MapGuide Open Source 1.1.0 Release Notes

This release is fully compatible with resources created using the previous MapGuide Open Source 1.0.x releases. If you uninstall the previous1.0.x release and then install this one in the same location your existing Resource Database will be preserved.

This release is compatible with FDO 3.2.0.

New Features

This section lists the notable new features in this release.

FDO 3.2

MapGuide Open Source now supports providers that use the FDO 3.2 API. The open source FDO 3.2 providers are available from http://fdo.osgeo.org.

Direct KML support

This feature allows layers defined in MapGuide to be displayed as layers in Google Earth. See MapGuide Open Source RFC 4 for details.

Enhanced Long Transaction Support

The FeatureService API now provides a method to change the long transaction name associated with a feature source for the caller's session.

.NET support

The collection classes now support indexing using [] and the foreach operation.

Classes now have properties where appropriate.

API Changes

MgByteReader

The MgByteReader class has new constructors and methods to make it more useful. MgByteReaders can now be created on a file, string or bytes. There is also a ToFile method to write the contents of the reader to a file, and methods to rewind the reader.

New Base classes

MgLayer, MgMap and MgSelection now have new superclasses; they are respectively MgLayerBase, MgMapBase and MgSelectionBase. No new methods have been added by this refactoring, but the methods are now distributed between the subclass and superclass. For .NET or Java applications, if the following APIs are used then casts will need to be done:

When using

• MgLayerCollection.GetItem(Int32 index)
• MgLayerCollection.GetItem(CREFSTRING name)
• MgReadOnlyLayerCollection.GetItem(Int32 index)

the returned object has type MgLayerBase. This object can always be safely cast to a MgLayer object.

For example,
MgLayer myLayer = myCollection.GetItem(i);
needs to be changed to
MgLayer myLayer = myCollection.GetItem(i) as MgLayer; // for .NET
MgLayer myLayer = (MgLayer)myCollection.GetItem(i); // for Java

When using

• MgMapCollection.GetItem(Int32 index)
• MgMapCollection.GetItem(CREFSTRING name)

the returned object has type MgMapBase. This object can always be safely cast to a MgMap object.

Note that where a MgMapBase, MgLayerBase or MgSelectionBase is the type of a parameter to a method, the respective objects of type MgMap, MgLayer and MgSelection can be used in their place.

Limitations

Compile error with FDO GenericRdms Unit test on Fedora Core 4

On Fedora Core 4, you will get an error when compiling FdoInsertTest.cpp:
OpenSource_FDO/Providers/GenericRdbms/Src/UnitTest/Common/FdoInsertTest.cpp:1492: error: integer constant is too large for 'long' type

To resolve this error, add LL to the end of line 1492 so that it becomes:
return (FdoInt64) 9223372036854775807LL;

Compile error with regex_traits.hpp on Fedora Core 6

On Fedora Core 6, in file OpenSource_FDO/Thirdparty/boost_1_32_0/boost/regex/v4/regex_traits.hpp, change lines 320 to 322 to the following (removes two occurrences of <regex_wchar_type>):

c_regex_traits()
{ init(); }
~c_regex_traits()
