   This is expected that constraints can call getConstraintType() if they are filtered:

    return context.checkConsistency(fixit=1, filter={'constraint_type': 'post_upgrade'},)
  Module Products.ERP5Type.Core.Folder, line 1476, in checkConsistency
    error_list.extend(obj.fixConsistency(filter=filter, **kw))
  Module Products.ERP5Type.Base, line 2714, in fixConsistency
    return self.checkConsistency(fixit=True, filter=filter, **kw)
  Module Products.ERP5Type.Core.Folder, line 1476, in checkConsistency
    error_list.extend(obj.fixConsistency(filter=filter, **kw))
  Module Products.ERP5Type.Base, line 2714, in fixConsistency
    return self.checkConsistency(fixit=True, filter=filter, **kw)
  Module Products.ERP5Type.Core.Folder, line 1462, in checkConsistency
    **kw
  Module Products.ERP5Type.Base, line 2686, in checkConsistency
    for constraint_instance in self._filteredConstraintList(filter):
  Module Products.ERP5Type.Base, line 2739, in _filteredConstraintList
    constraints = [x for x in constraints if x.__of__(self).getConstraintType() in \

   There is a missing "r" on the link, acording to apache documentation:

    Additionally you have to create symbolic links named hash-value.rN. And you should always make sure this directory contains the appropriate symbolic links.

This reverts commit 89aa2a6b.
The assumption that FOR UPDATE was unnecessary is wrong: when SQLDict
reserves similar activities, it will race against these primo-reservations.
So this change actually opens the possibility for duplicate activity
reservation.
Revert this change until (hopefully) a better fix is implemented.

In case of network problems, the http requests made to google during
login may take too long and cause global unavailability of the ERP5
instance.

Today we saw in long request logs:

oauth2client does not expose an API to set a timeout, but it allows
passing a custom http instance where we can set a timeout.

On Zope2 this method does not exist and this caused a test failure
