Add keyword argument support to the "dump", "dumps", and "Pickler" callables in the cPickle module. This provides better API compatibility with the pure-Python pickle module. There are several other differences, but this one is probably the most user-visible and likely to be noticed. And it's easy to fix! The callables chosen are those that take multiple arguments. This patch addresses bug #888594
Logged In: YES user_id=21627 The patch is incorrect: the first argument is called object. Please also double-check consistency with the documentation. I'm going to apply the revised version for 2.4 only, as this is a subtle behaviour change. If you think it should be backported to 2.3 as well, please indicate so.
Logged In: YES user_id=908995 The patch does what it claims to do--be more compatible with the pure-Python pickle module, which uses "obj" as the first argument. I noticed that when I made the change and should have mentioned it in the initial comment. I intend to submit a patch to the documentation to change the first argument to "obj". Although I think "object" is better, someone might be relying on the pure-Python using obj even though the documentation is wrong about that. I see no reason to backport this to 2.3.
Logged In: YES user_id=908995 Thanks Martin. I submitted the documentation update as SF #999280, and this patch addressed bug #888594, which can now be closed.
