zstandard: vendor python-zstandard 0.13.0 Version 0.13.0 of the package was just released. It contains an upgraded zstd C library which can result in some performance wins, official support for Python 3.8, and a blackened code base. There were no meaningful code or functionality changes in this release of python-zstandard: just reformatting and an upgraded zstd library version. So the diff seems much larger than what it is. Files were added without modifications. The clang-format-ignorelist file was updated to reflect a new header file in the zstd distribution. # no-check-commit because 3rd party code has different style guidelines Differential Revision: https://phab.mercurial-scm.org/D7770

====================================
Testing head checking code: Case C-2
====================================

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 C: checking case were the branch is only partially obsoleted.
TestCase 1: 2 changeset branch, only the head is rewritten

.. old-state:
..
.. * 2 changeset branch
..
.. new-state:
..
.. * 1 new changesets branches superceeding only the head of the old one
.. * base of the old branch is still alive
..
.. expected-result:
..
.. * push denied
