Yes, the discussion is here:
(the apache mailing list archive still doesn't work for me).
May I suggest an approach that doesn't force me to find expensive
workarounds for more and more missing information the svn APIs return:
Use a mask parameter which specifies which members of a returned struct
get filled in by the API and which ones are not. That way, the less one
specifies in the mask the faster the API returns, but if necessary
everything necessary can still be returned in one tree walk without the
need to invoke several other APIs which also do the very same tree walk.
If you need an example, have a look at TVM_GETITEM and the TVITEMEX struct:
The mask member specifies which members of the struct will be filled by
the TVM_GETITEM call.
This also has the advantage that new data can be added later without
changing the API.
