Re: [boost] [range] [1.40] iterator_range::size broken for non-random access iterators

We were just upgrading from 1.34.1 to 1.39.0 and I ran into this issue which I note is still in the trunk (and I would assume the 1.40 candidate).

The definition of iterator_range::size is using operator- where it should be using std::distance as it did in boost 1.34 days:

I'm not sure why it would have changed but it's no longer working with bi-directional iterators, etc. Can we put back the old version? Can we get this fixed for 1.40? Thanks,

This change is intentional. We decided that iterator_range::size should be O(1), or else it shouldn't compile. To get the old behavior, you can use boost::distance in boost/range/distance.hpp. HTH, -- Eric Niebler BoostPro Computing http://www.boostpro.com
