STINNER Victor <victor.stin...@haypocalc.com> added the comment: New implementation of finer lock grain in _hashlibopenssl: only create the lock at the first update with more than 8 KB bytes. Object creation/deallocation is faster if we hash less than 8 KB.
Changes between hashopenssl_threads-4.diff and my new patch: fix the deadlock in ENTER_HASHLIB() (for the GIL) without speed change (because we don't change the GIL state if we don't use a lock). Changes between py3k trunk and my new patch: - release the GIL with large byte string => faster with multiple CPUs - fix EVP_get_block_size() and EVP_get_digest_size(): the context was not protected by the lock!
