amend: query the wdir parent after taking lock (issue5266) If we query wdir parent without taking a lock, that can lead to bugs because the wdir parent can change is another process has changed the wdir parent. One such example of this was issue 5266. When a user is running amend and that amend is waiting for commit message, the user runs another amend which waits for lock. The second amend is waiting for lock, but has already read the description from the parent of working directory to use. Once the first amend completes the wdir parent changes but we still have the description from an old wdir parent. This patch fixes the bug by querying the description after taking lock. Attempts were made to add test for this but the results were unstable because they depend on time in which lock is released.

============================================
Testing obsolescence markers push: Cases B.5
============================================

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 B: pruning case
TestCase 5: Push of a children of changeset which successors is pruned

B.5 Push of a children of changeset which successors is pruned
==============================================================

.. This case Mirror A.4, with pruned changeset successors.

.. Marker exist from:

..  * `A ø⇠○ A'`
..  * `B ø⇠○ B'`
..  * chain from B
..  * `B' is pruned`
