depthcache: ignore permission and OS errors when writing This cache is related to the obshashrange one and we update it lazily by default. This can be an issue when pulling locally from a read only repository that was not configured for a more aggressive cache warming. The raised permission error was uncaught and could crash the whole process. Errors during Cache update should not block Mercurial operations.

====================================
Testing head checking code: Case B-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 B: simple case involving pruned changesets
TestCase 2: multi-changeset branch, head is pruned, rest is superceeded, through other

.. old-state:
..
.. * 2 changeset branch
..
.. new-state:
..
.. * old head is rewritten then pruned
.. * 1 new branch succeeding to the other changeset in the old branch (through another obsolete branch)
..
.. expected-result:
..
.. * push allowed
