Testing obsolescence markers push: Cases A.4
============================================
Mercurial pushes obsolescences markers relevant to the "pushed-set", the set of
all changesets that requested to be "in sync" after the push (even if they are
already on both side).
This test belongs to a series of tests checking such set is properly computed
and applied. this does not tests "obsmarkers" discovery capabilities.
Category A: simple cases
Testcase 4: Push in the middle of the obsolescence chain
A.4 Push in the middle of the obsolescence chain
================================================
.. (Where we show that we should not push the marker without the successors)
..
.. {{{
.. B ◔
.. |
.. A⇠ø⇠○ A'
.. |/
.. ● O
.. }}}
..
.. Markers exist from:
..
.. * `A ø⇠○ A'`
.. * chain from A
..
.. Command runs:
..
.. * hg push -r B
..
.. Expected exchange:
..
.. * Chain from A
..
.. Expected Exclude:
..
.. * `Ai ø⇠○ A'`
