I also found this useful web page: http://ask.sagemath.org/question/123/what-is-the-standard-pickle-jar-for-and-how-do-i So assuming your shell is bash, I can: export SAGE_PICKLE_JAR="pickle" Then run the tests in sage/combinat/crystals. After that, there is a file $SAGE_ROOT/tmp/pickle_jar-4.6.2.alpha3 containing pickles, including the offending ones _class__sage_combinat_crystals_affine_AffineCrystalFromClassicalAndPromotion_with_category_element_class__.sobj _class__sage_combinat_crystals_tensor_product_CrystalOfTableaux_with_category_element_class__.sobj _class__sage_combinat_crystals_tensor_product_TensorProductOfCrystalsWithGenerators_with_category__.sobj _class__sage_combinat_crystals_tensor_product_TensorProductOfCrystalsWithGenerators_with_category_element_class__.sobj and corresponding .txt files. Next I go to $SAGE_ROOT/data/extcode/pickle_jar and extract the archive with the command: tar xjvf pickle_jar.tar.bz2 this creates a subdirectory $SAGE_ROOT/data/extcode/pickle_jar/pickle_jar into which I copy the above eight .sobj and .txt files. Then I remake the pickle_jar with tar cjvf pickle_jar.tar.bz2 pickle_jar I am in the directory $SAGE_ROOT/data/extcode/pickle_jar for this command. For me this fixed three out of four tests in sage/structure/sage_object.pyx. I still get a failure with: _class__sage_combinat_crystals_tensor_product_CrystalOfTableauxGeneric_with_category_element_class__.sobj Dan -- You received this message because you are subscribed to the Google Groups "sage-combinat-devel" group.
