.. to classify the test as upgrade test. This helps projects to
  rely on the same code base.

When a request got retried after a conflict error, a:

    TypeError: getPublisherDeadlineValue() takes exactly 1 argument (0 given)

was raised.

Instead of adding a new test to cover this, run all tests from
ZPublisher module (except a few which had suspicious errors).

This actual error happened when running
ZPublisher.tests.testPublish.testPublisher before the fix.

This reverts commit 99185dd0.

  The bug was already fixed on nexedi/erp5@e57dd4fb

  This change is for Production instances where corruption occured only.

When a first migration was reverted for any reason (e.g. ConflictError),
the assertion failed because __setstate__ was not called yet to fix the
class back to the old one.

   Whenever used via activity nodes, it is not possible to discover IP of the server via portal absolute url.

    If two open orders are validated on the same transaction, archivePrevious script will get the an already archived as catalog will be outdated.

(cherry picked from commit 791113d0)

This reverts commit 5c8b7ab0.

    This allow including more items to be ignored, preventing diffs from pure development.

(cherry picked from commit 910b7672)

  This is required for multiple sites support and allow us write unit tests and not create a 100 lines mock.

   This allow the administrator define which Login portal types are searched.

Prefer to use Login_checkExistence from this Skins over the version on erp5_base.

Also extend tests to cover recently changes

This reverts commit 9eb3828d.

   This is an alternetive way to login using Certificates. Probably this format
   will evolve into use caucase;  however this only introduce some most basic features.

   Use Certificate Login for store login definitions

   Move test into the business template

  Please squash me in future.

  This optimisation aims reduce the potential activity leak when over launching accross multiple activities/transactions the updateSimulation.
  SubscriptionItem: Add a method to call updateSimulation from sqldict activities
    updateExpandableRootSimulation allow launch activities in a safer matter and have lower calls.

  If the user wants actitivites, it should create multiples StandardBT5ConfiguratorItems,
  This should accellerate Tests based on ERP5Configurator.

  This should be recoded, but it should speed up bootstrap of a site,
  as get modified objects are not called.

It the user don't have fully permission on the object (already changed state), this set will fail to check if source should be defined.

Ignore list is usefull when you have old business templates in production (used to include data for example) and test business templates on test environment (ie;: erp5_test_ui_core). This allow us control the dump to assert changes easily.

1 minute is too agressive for general use.

  The upgrade ordering seems buggy and requires to force reinstall it

This allow during a subscription process, create a user and them create all
documents using that user w/o rely on proxy roles (keeping good ownership
across the documents).

Without this (on slapos master ui) the redirection places value unquoted causing parser to fail later on when resolve {n.me}

  The user can be present from diferent logins, password tool only works with ERP5LoginUserMager
  users.
