Potential memory leak when assigning MSetItem values
I've traced a memory leak to a statement which assigns the values from an
MSetItem to a dictionary which is then appended to a list in python. We're
running python 2.7.3, xapian-core 1.2.15 and xapian-bindings 1.2.15. I've
provided an example which reproduces the behavior below. The example prints
the PID and has a few statements waiting for input to make observing the
be...

Potential memory leak when assigning MSetItem values
Olly, the process size does stay constant with the results from one query
set, but running other queries will cause it to grow (once). Is it possible
that this is a bug with the SWIG python bindings?

About xapian serialization on float/double variables
...re Document values with serialization approach when given value types meet float/double.
Such an approach is deployed on sort_key related fields as well, where the xapian requires KeyMaker::operator() must return an serialized float/dobule variable. Then heap sort comes and ranks the vector<MSetItem> items (multimatch.cc MultiMatch::get_mset()) by comparing serialized sort_keys (std::string) straightforwardly according to <IEEE-754 doubles>. Subsequently sort_keys will be unserialized when user needs to read its real float/double values during iterations of result MSet.
Obviously...

Letor: returning MSet after re-ranking
...for a delayed response.
The way I was thinking of performing reranking with updated weights was to
add a class MSetRanker (basically containing a copy of MSet to be
re-ranked) to Xapian public API, which would be a friend of MSet::Internal
class so that it could access/update the weights and sort MSetItems
accordingly, returning an updated MSet.
As you pointed out, two obvious issues with this are: 1) Unnecessary
addition to Xapian public API since this class is not useful beyond letor.
2) It gives access to MSet internals to end users
What would you suggest should be the way out to access MSet in...
