====================================
|
|
|
Testing head checking code: Case D-4
|
|
|
====================================
|
|
|
|
|
|
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 4: multi-changeset branch, split on multiple other, (base on its own new branch)
|
|
|
|
|
|
.. old-state:
|
|
|
..
|
|
|
.. * 2 branch (1 changeset, and 2 changesets)
|
|
|
..
|
|
|
.. new-state:
|
|
|
..
|
|
|
.. * 1 new branch superceeding the base of the old-2-changesets-branch,
|
|
|
.. * 1 new changesets on the old-1-changeset-branch superceeding the head of the other
|
|
|
..
|
|
|
.. expected-result:
|
|
|
..
|
|
|
.. * push the new branch only -> push denied (variant a)
|
|
|
.. * push the existing branch only -> push allowed (variant b)
|
|
|
.. (pushing all is tested as case A-7)
