dirstate: invalidate the dirstate change on transaction failure
If the change context lives inside a transaction, the change are not flushed to
disk on exit as this is delegated to the transaction. As a result we should
also delegate the part that do cleanup on failure.
The issue was caught by tests with other change, but it seems useful to fix this
as soon as possible.
====================================
Testing head checking code: Case A-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Category A: simple case involving a branch being superseded by another.
TestCase 7: multi-changeset branch, split on multiple other, (head on its own branch), same number of head
.. old-state:
..
.. * 2 branch (1-changeset, and 2-changesets)
..
.. new-state:
..
.. * 1 new branch superseding the head of the old-2-changesets-branch,
.. * 1 new changesets on the old-1-changeset-branch superseding the base of the other
..
.. expected-result:
..
.. * push allowed
