Hello all,
I am working on #18109 which does some major restructuring of the
IntegerListsLex class.
The problem is that breaks some pickles from the pickle jar. This is
completely understandable. Now my question is: what to do to fix this?
With #17842 (needs review by the way!) I got this traceback:
sage: sage.structure.sage_object.unpickle_all()
* unpickle failure:
load('/home/jdemeyer/.sage/temp/tamiyo/22824/dir_huFT4h//pickle_jar/_class__sage_combinat_integer_list_IntegerListsLex__.sobj')
Traceback (most recent call last):
File "sage/structure/sage_object.pyx", line 1473, in
sage.structure.sage_object.unpickle_all
(build/cythonized/sage/structure/sage_object.c:14187)
object = load(os.path.join(dir,A))

sage.structure.sage_object.loads
(build/cythonized/sage/structure/sage_object.c:12709)
return unpickler.load()
UnpicklingError: NEWOBJ class argument isn't a type object
But now what? I tried
from sage.structure.sage_object import register_unpickle_override
register_unpickle_override('sage.combinat.integer_list',
'IntegerListsLex', _unpickle_old_IntegerListsLex)
but it seems that the function _unpickle_old_IntegerListsLex() is not
called.
