* [3.9] bpo-41100: Support macOS 11 and Apple Silicon (GH-22855) (GH-23295)Ronald Oussoren2020-11-228-254/+981
| | | | | | | | | | | | | | | | | | | | * [3.9] bpo-41100: Support macOS 11 and Apple Silicon (GH-22855) Co-authored-by: Lawrence D’Anna <lawrence_danna@apple.com> * Add support for macOS 11 and Apple Silicon (aka arm64) As a side effect of this work use the system copy of libffi on macOS, and remove the vendored copy * Support building on recent versions of macOS while deploying to older versions This allows building installers on macOS 11 while still supporting macOS 10.9.. (cherry picked from commit 41761933c1c30bb6003b65eef1ba23a83db4eae4) Co-authored-by: Ronald Oussoren <ronaldoussoren@mac.com> * Back port of changes to _decimal to support arm64 * temp_dir is in test.support in 3.9
* bpo-40791: Make compare_digest more constant-time. (GH-20444)Miss Islington (bot)2020-11-211-1/+1
| | | | | | | | | | * bpo-40791: Make compare_digest more constant-time. The existing volatile `left`/`right` pointers guarantee that the reads will all occur, but does not guarantee that they will be _used_. So a compiler can still short-circuit the loop, saving e.g. the overhead of doing the xors and especially the overhead of the data dependency between `result` and the reads. That would change performance depending on where the first unequal byte occurs. This change removes that optimization. (This is change GH-1 from https://bugs.python.org/issue40791 .)
