I have just added serialization to Boost.Ptr container. I briefly discussed an issue with Robert, namely that the current implementation calls clear() before reading the new values.
The alternative is to provide roll-back guarantee by default by creating a local container and swap() in the end. By default this would temporarily use more memory.
IMO we should go for the strong guarantee. Any thoughts?
I think the basic guarantee is enough here. Truly paranoid users can copy+swap themselves, but for most purposes you are better off not having two copies of the container in memory. Most people need better performance more than they need the strong guarantee. Doug
