If a
Pickler
instance already has methods in its dispatch table, do not override them. This bug showed up in cloudpipe/cloudpickle#253 and running this benchmark where theCloudpickler
instances derives from the C_Pickler
and most custom saving methods are insidedispatch_table
, notdispatch
.Given the current
set_loky_pickler
structure (private, nestedCustomizablePickler
class), it is hard to write a proper test for it.
