topicmap: massive rework
Massively rework the way we build and use topicmap. This bring massive performance
benefit.
Topic map use to be a fully independant thing that we would switch on and off
globaly. The caching on disk was broken so the performance were atrocious.
Intead, now the topic are inherited from the 'immutable' map. We gave up on
storing them on disk for now since the mutable set is usually small enough.
The activation is done by hacking new "filter" on the repository and detection
when they are one. This is hacky but core is hard to wrap here.
Overall this whole wrapping is really scary and we should massage core API to
help it.

Logilab SA <contact@logilab.fr> ----------------------------------------- Good practice for (early) users of evolve ----------------------------------------- Avoid unstability ----------------- The less unstability you have the less you need to resolve. Evolve is not yet able to detect and solve every situation. And your mind is not ready neither. Branch as much as possible -------------------------- This is not MQ; you are not constrained to linear history. Making a branch per independent branch will help you avoid unstability and conflict. Rewrite your changes only ------------------------- There is no descent conflict detection and handling right now. Rewriting other people's changesets guarantees that you will get conflicts. Communicate with your fellow developers before trying to touch other people's work (which is a good practice in any case). Using multiple branches will help you to achieve this goal. Prefer pushing unstability to touching other people changesets -------------------------------------------------------------- If you have children changesets from other people that you don't really care about, prefer not altering them to risking a conflict by stabilizing them. Do not get too confident ------------------------ This is an experimental extension and a complex concept. This is beautiful, powerful and robust on paper, but the tool and your mind may not be prepared for all situations yet.
