Jack: I've updated the PR, improving compatibility with the "blake3" package on PyPI. I took your notes, and also looked at the C module you wrote. The resulting commit is here: https://github.com/python/cpython/pull/31686/commits/37ce72b0444ad63fd1989ad36be5f7790e51f4f1 Specifically: * derive_key_context is now a string, which I internally encode into UTF-8. * I added the AUTO member to the module, set to -1. * max_threads may not be zero; it can be >= 1 or AUTO. * I added the reset() method. Some additional thoughts, both on what I did and on what you did: * In your new() method, your error string says "keys must be 32 bytes". I went with "key must be exactly 32 bytes"; the name of the parameter is "key", and I think "exactly" makes the message clearer. * In my new() method, I complain if the derive_key_context is zero-length. In your opinion, is that a good idea, or is that overly fussy? * In your copy() method, you hard-code Blake3Type. It's considered good form to use type(self) here, in case the user is calling copy on a user-created subclass of Blake3Type. * In your copy() method, if the original has a lock created, you create a lock in the copy too. I'm not sure why you bother; I leave the lock member uninitialized, and let the existing logic create the lock in the copy on demand. * In the Blake3_methods array, you list the "update" method twice. I suspect this is totally harmless, but it's unnecessary. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue39298> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
