Bug report

Much error generating code in the pickle module is not tested at all. As result, not only exception types and messages can differ between Python and C implementations, but other bugs are left unnoticed:

  • NameError in formatting one of error messages.
  • "Can't pickle" in the error message during unpickling.
  • Error message including the repr of wrong object.
  • Some errors are only detected in one of implementations (Python or C).
  • Crash in untested corner case (Crash after error in PickleBuffer #122306).

I am going to add more tests and fix the most odious errors. This will be backported to 3.12 and 3.13, but the backport to 3.12 will have more lenient variants of tests. Late, I will unify and improve other error messages (this is for main only).

pythongh-122311: Improve and unify pickle errors
554abbc 
* Raise PicklingError instead of UnicodeEncodeError, ValueError
  and AttributeError in both implementations.
* Chain the original exception to the pickle-specific one as __context__.
* Include the error message of ImportError and some AttributeError in
  the PicklingError error message.
* Unify error messages between Python and C implementations.
* Refer to documented __reduce__ and __newobj__ callables instead of
  internal methods (e.g. save_reduce()) or pickle opcodes (e.g. NEWOBJ).
* Include more details in error messages (what expected, what got).
* Avoid including a potentially long repr of an arbitrary object in
  error messages.
