evolvestate: add a class to wrap the state of `hg evolve` command
This patch adds a new file which contains a class which will act as a wrapper
for the data to be stored or used during the `hg evolve` command. This patch
just introduces the file and does not use it at the moment. The upcoming patches
will start using it.
====================================
Testing head checking code: Case D-7
====================================
Mercurial checks for the introduction of new heads on push. Evolution comes
into play to detect if existing branches on the server are being replaced by
some of the new one we push.
This case is part of a series of tests checking this behavior.
Category D: remote head is "obs-affected" locally, but result is not part of the push
TestCase 7: single changesets, superseeded multiple time then pruned (on a new changeset unpushed) changeset
This is a partial push variation of B6
.. old-state:
..
.. * 1 changeset branch
..
.. new-state:
..
.. * old branch is rewritten onto another one,
.. * The rewriting it again rewritten on the root
.. * the new version is then pruned.
..
.. expected-result:
..
.. * push allowed
