Hi, I have just tracked down another issue with the VPB serializer. This time the issue arises when you try to add an optional layer (nb: this fails at an earlier point with the code in trunk at the moment, I will be submitting a fix for that tomorrow, though the issue can be demonstrated without it).
When build options that contain an optional layer are serialized an empty entry
is added to the list.
e.g.
OptionalLayerSet 2 {
""
"AnOptionalLayerName"
}
I believe the bug is in BuildOptionsIO.cpp, probably in the SetSerializer
class, thought I haven't managed to track it down exactly yet.
The attached files can be used to reproduce the error.
original.source is a copy of the build_master.source that was written out when
I tried to add an optional set.
If you run:
osgdem -s original.source --so original_resaved.source
an error will be produced as the file cannot be read.
I have also attached 'fixed.source'. This has had the "" removed (note that the
number of items in the set is still set to 2). This file can be de-serialized
and then re-serialized but the result has the extra "" included. This can be
done by running:
osgdem -s fixed.source --so fixed_result.source
Cheers,
Brad
