      py2/py3: Make Products code compatible with both python2 and python3. · a17bb910
      Arnaud Fontaine authored
      Done through various 2to3 fixers (zope.fixers, modernize, future) and manual
      changes. This is a single commit so that we have a clearer picture of how code
      converted with my2to3 should look like.
      
      Except straightforward @implementer decorator 2to3 fixer, only product/ folder
      was considered as the goal was to be able to create an ERP5Site.
      
      * Use @implementer decorator introduced in zope.interface 3.6.0 (2010):
      
        The implements syntax used under Python 2.X does not work under 3.X, since it
        depends on how metaclasses are implemented and this has changed. Instead it
        now supports a decorator syntax (also under Python 2.X).
      
        Applied thanks to 2to3 `zope.fixers` package.
      
      * Use `six.moves` rather than `future` install_aliases() feature because the
        latter use unicode_literals and "wraps" module aliases so that unicode() are
        returned for text rather than str() (Python2 standard library). This notably
        breaks BusinessTemplate code which uses urllib quote() for filesystem paths...
      
      * No more unbound methods in python3 so use six.get_unbound_function().
      
      * dict.(iteritems,iterkeys,itervalues)() => six.\1(dict) thanks to `dict_six`
        2to3 fixer from `modernize`:
        $ python-modernize -w -f dict_six product/
      
      * Manually make sure that dict.{items,values,keys}() returns a real list when it
        is latter modified rather than a dict_{items,values,keys} (ensure_list()). By
        default, 2to3 blindly does list(dict.{items,values,keys}()) which is not
        acceptable from performances point of view. With my2to3, this will be possible
        to handle such case automatically.
      
      * Replace cStringIO.StringIO() by six.moves.cStringIO() (a module alias for
        cStringIO.StringIO() on py2 and io.StringIO() on py3).
      
      * Use six.text_type which maps to unicode() on py2 and str() on py3. This also
        makes a clearer difference between text and binary strings.
      
      * Replace map()/filter() with lambda function by list comprehension (this has
        the benefit to avoid casting to list for py3 as it returns iterators).

      ZODB Components: erp5_core: Migrate Movement Document from filesystem. · e8e5f273
      Arnaud Fontaine authored
      * Import Movement Document:
        + Event
          + MailMessage
        + Project
        + ImmobilisationMovement
      * Imported by IMovement:
        + IAccountingMovement
        + IAmountGenerator
          + AmountGeneratorMixin
          + AmountGeneratorLine
        + IAssetMovement
        + IProductionMovement
      * Used by MovementGeneratorMixin:
        + IMovementGenerator
        + IMovementList
      
      Also, define providesI<INTERFACE_NAME>() on Base class for migrated Interfaces as
      these needs to be available before bt5 containing the ZODB Component Interfaces are
      upgraded (see also c86107bf). Otherwise, testUpgradeInstanceWithOldDataFs fails as
      z_catalog_item_list (newActiveProcess() from upgrader) calls providesIMovement().
