push: put phase in the same bundle2 than changegroup and obsmarkers

Note that the usual phase push from core will be performed in all case. But the
discovery should find already in sync phase at that time. The old ways sync will
be properly skipped when this logic is introduced into core.

=============================
Mutable History For Mercurial
=============================

This package supplies the ``evolve`` extension for Mercurial, which
provides several commands to mutate history and deal with the
resulting issues.

It also:

    - enables the "changeset obsolescence" feature of Mercurial
    - issues several warning messages when trouble appears in your repository

**This extension is experimental and not yet meant for production.**

You can enable it by adding the line below to the ``extensions``
section of your hgrc::

    evolve = PATH/TO/mutable-history/hgext/evolve.py

We recommend reading the documentation first. An online version is
available here:

    http://hg-lab.logilab.org/doc/mutable-history/html/

Or see the ``doc/`` directory for a local copy.

Contribute
==========

The simplest way to contribute is to issue a pull request on Bitbucket
(https://bitbucket.org/marmoute/mutable-history). Alternatively, you
can use the patchbomb extension to send email to mercurial
devel. Please make sure to use the evolve-ext flag when doing so. You
can use a command like this:

    hg email --to [e-mail] --flag evolve-ext --rev '<your patches>'

See also
http://mercurial.selenic.com/wiki/ContributingChanges#Patch_descriptions
for guidelines on the patch description.

Please don't forget to update and run the tests when you fix a bug or
add a feature. To run the tests:

    cd tests
    python run-tests.py --with-hg=/path/to/hg

However, some cutting-edge changes may be found in a mutable repository hosted
by logilab before they are published.

Be sure to check latest draft changeset before submitting new changesets.
