Hi John,
I think I found a problem in function ibis::column::selectValuesT.
When a query does not specify a where clause or when mask.cnt() ==
mask.size(), the method ibis::column::selectValuesT return a pointer on
raw data ...
Which cause the bundle segment method to reorder the raw data !
template <typename T>
long ibis::column::selectValuesT(const bitvector& mask,
ibis::array_t<T>& vals) const {
...
...
if (mask.cnt() == mask.size())
return getValuesArray(&vals);
...
...
if (tot == mask.size()) { // read all values
ierr = ibis::fileManager::instance().getFile(dfn, vals);
return ierr;
}
}
Regards,
Alexandre
