Title:
  [6.1][account] slow large invoice validation because validate is
  called for every line

Status in OpenERP Addons (modules):
  Won't Fix

Bug description:
  edit account/account.py
  and introduce some traceback print statement this way:

  @@ -1378,6 +1385,9 @@
       # Validate a balanced move. If it is a centralised journal, create a move.
       #
       def validate(self, cr, uid, ids, context=None):
  +#        import traceback
  +#        traceback.print_stack()
  +        print "validate", ids
           if context and ('__last_update' in context):
               del context['__last_update']

  
  Now restart your server and try to validate an invoice with many lines, like 10 (cool you are not in production).
  As you can see, that slow validate method is called for every invoice line, making the whole process very slow. Here in production it takes like 2 minutes to validate a 50 lines (with Brazilian taxes) invoice... Not very user friendly.

  You'll see a similar traceback for every line:

    File "/opt/openerp-trunk/server/bin/osv/orm.py", line 181, in <lambda>
      return lambda *args, **argv: attr(self._cr, self._uid, [self._id], *args, **argv)
    File "/opt/openerp-trunk/addons/l10n_br_account/invoice.py", line 323, in action_move_create
      self.pool.get('account.move.line').write(cr, uid, [move_line.id for move_line in inv.move_id.line_id], {'ref': inv.internal_number})
    File "/opt/openerp-trunk/addons/account_payment_extension/account_move_line.py", line 168, in write
      return super(account_move_line, self).write(cr, uid, ids, vals, context, check, update_check)
    File "/opt/openerp-trunk/addons/account/account_move_line.py", line 1171, in write
      result = super(account_move_line, self).write(cr, uid, ids, vals, context)
    File "/opt/openerp-trunk/server/bin/osv/orm.py", line 3414, in write
      result += self._columns[field].set(cr, self, id, field, vals[field], user, context=rel_context) or []
    File "/opt/openerp-trunk/server/bin/osv/fields.py", line 830, in set
      self._fnct_inv(obj, cr, user, id, name, value, self._fnct_inv_arg, context)
    File "/opt/openerp-trunk/server/bin/osv/fields.py", line 881, in _fnct_write
      model.write(cr, uid, [t_id], {args[-1]: values}, context=context)
    File "/opt/openerp-trunk/addons/account/account.py", line 1240, in write
      self.validate(cr, uid, ids, context=context)
    File "/opt/openerp-trunk/addons/account/account.py", line 1389, in validate
      traceback.print_stack()
  validate [543]

  
  In "/opt/openerp-trunk/addons/account/account_move_line.py", line 1171, in write we still have a table of ids, so the hell loop is not born yet.
  It will actually birth inside the ORM in "/opt/openerp-trunk/server/bin/osv/orm.py", line 3414, in write
  where you'll iterate over each id.
  I tend to think this is a first bad implementation, may be the real source of the bug. After this, we call validate for each account move line...

  
  Still, it looks like you attempted to prevent this by strong a context c['novalidate'] = True flag.
  a grep gives us:

  ~# grep -r novalidate /opt/openerp-trunk/addons/account/
  /opt/openerp-trunk/addons/account/account.py:        c['novalidate'] = True
  /opt/openerp-trunk/addons/account/account.py:            c['novalidate'] = True

  But as you can see, it's a bit like marketing: totally useless. Sounds
  like a good intention but it has absolutely no effect at all, it's
  just no used.

  So, I let you determine what is the proper fix, something in the ORM
  or some "novalidate" trickery before somebody remove the trick by
  mistake again to fox some side effect bug...

  Hope this helps.
