We have definitions for a number of properties both from the WSP spec document and from those used by wireshark. These properties are built into samba (generated from csv files). This commit allows extra properties to be added on the fly in a custom csv file, the format of the csv file is the same as that used in the build. This allows us to add some 'unknown' properties on the fly, although we would hope that information regarding these properties would be incorporated into the build in due course.

WSP properties are described in a number of sections in the MS-WSP protocol
document. The document says that all properties are categorised as follows
"GUID and PropId: Together, these parameters establish the unique identifier
for documents.
isColumn: A boolean value set to TRUE if, and only if, the property can be
returned as a requested property as specified in the
ProjectionColumnsOffsets argument to a RunNewQuery Generic Search
Service (GSS) abstract interface call.
inInvertedIndex: A boolean value set to TRUE if, and only if, the property can
be an argument to CContentRestriction within the
RestrictionSet argument to a RunNewQuery GSS abstract
interface call.
columnIndexType: This parameter defines whether sorting, grouping, and
filtering are allowed for this property, as defined in the
SortOrders, Groupings, and Restrictions parameters of the
RunNewQuery GSS abstract interface call.
The columnIndexType parameter is a string set to one of the
following"
additionally the property type 'VT_XXXX' and max size are known
However, not all properties described match this, only properties mentioned in
the "full property table" are fully described, others mentioned e.g. in
"Standard" & "Open" property sections (and associated tables) have just the
GUID, propid & property data type described, still other properties are only
mentioned in the Example section and one needs to manually extract the info.
We need the property descriptions and some scripting helps here, in this
directory there is
librpc/wsp/allprops-from-ms-wsp-spec.csv:
a csv file made from the "full property table" exported from the html
oneline version online version of MS-WSP open specification document.
extra-props.csv:
a csv file of the same format containing the other properties mentioned
above and additionally a few more from the wireshark repo)
and in directory source4/scripting/bin
gen_wsp_props.py:
a simple python script to generate code from the csv files above,
extra-props.csv was generated by basically grabbing the property definititions
from the wireshark repo
https://github.com/wireshark/wireshark.git(epan/dissectors/packet-mswsp.c
and comparing against the properties we already have
The build generates code from the csv file mentioned above which is built into
the NDR_WSP subsystem.
