stabilize: improve unstable selection heuristic
Without argument, stabilize was picking the first in:
"unstable() and ((suspended() or obsancestors(::.))::)"
which usually returned the "oldest" unstable revision in parent
predecessors descendants. This revision is interesting because it
usually gives "soft" merges but rebasing it left the working directory
on a remote branch, which was very confusing.
The new heuristic picks an unstable changeset which can be rebased on
top of the parent revision, or on top of one of its descendants
(selected in revision order). This has the advantage of selecting a
revision which can be rebased on the current subtree, and leave the
working directory in a more convenient location.
=============================
Mutable History For Mercurial
=============================
:obsolete:
Introduce an ``obsolete`` concept that tracks new versions of rewritten
changesets.
:evolve:
A collection of commands to rewrite the mutable part of the history.
**These extensions are experimental and are not meant for production.**
See doc/ directory for details
Contribute
==================
The simplest way to contribute is to issue a pull request on bitbucket.
However, some cutting edge change may be found in a mutable repository hosted
by logilab before they are published.
