touch: prompt the user for what to do with the revived changeset This patch improves our interface for reviving changesets. This patch makes touch not assume that the user wants to create divergence by default and gives a prompt instead. The prompt is skipped for changeset that have no living successor as no divergence would be created by reviving them anyway. To restore the previous behavior, one should now use the --allowdivergence flag. The prompt looks like: [10] <description> reviving this changeset will create divergence unless you make a duplicate. (a)llow divergence or (d)uplicate the changeset? a In further patches we will want to add one more choice to that prompt, for example having a marker between the old and revived nodes but no divergence displayed on the UI.

-----------------------------------------
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 pratice 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.
