* gh-99108: Replace SHA2-224 & 256 with verified code from HACL* (#99109)Jonathan Protzenko2023-02-0718-350/+1779
| | | | | | | | | | | | | | | | | | | | | | replacing hashlib primitives (for the non-OpenSSL case) with verified implementations from HACL*. This is the first PR in the series, and focuses specifically on SHA2-256 and SHA2-224. This PR imports Hacl_Streaming_SHA2 into the Python tree. This is the HACL* implementation of SHA2, which combines a core implementation of SHA2 along with a layer of buffer management that allows updating the digest with any number of bytes. This supersedes the previous implementation in the tree. @franziskuskiefer was kind enough to benchmark the changes: in addition to being verified (thus providing significant safety and security improvements), this implementation also provides a sizeable performance boost! ``` --------------------------------------------------------------- Benchmark Time CPU Iterations --------------------------------------------------------------- Sha2_256_Streaming 3163 ns 3160 ns 219353 // this PR LibTomCrypt_Sha2_256 5057 ns 5056 ns 136234 // library used by Python currently ``` The changes in this PR are as follows: - import the subset of HACL* that covers SHA2-256/224 into `Modules/_hacl` - rewire sha256module.c to use the HACL* implementation Co-authored-by: Gregory P.

* gh-59956: Partial Fix for GILState API Compatibility with Subinterpreters ↵Eric Snow2023-02-062-21/+7
| | | | | | | | | | | (gh-101431) The GILState API (PEP 311) implementation from 2003 made the assumption that only one thread state would ever be used for any given OS thread, explicitly disregarding the case of subinterpreters. However, PyThreadState_Swap() still facilitated switching between subinterpreters, meaning the "current" thread state (holding the GIL), and the GILState thread state could end up out of sync, causing problems (including crashes). This change addresses the issue by keeping the two in sync in PyThreadState_Swap(). I verified the fix against gh-99040. Note that the other GILState-subinterpreter incompatibility (with autoInterpreterState) is not resolved here. https://github.com/python/cpython/issues/59956
* gh-101609: Fix "‘state’ may be used uninitialized" warning in ↵Nikita Sobolev2023-02-061-2/+3

* gh-76961: Fix the PEP3118 format string for ctypes.Structure (#5561)Eric Wieser2023-02-054-33/+111
| | | | | | | | | | | | | | | | | | | | The summary of this diff is that it: * adds a `_ctypes_alloc_format_padding` function to append strings like `37x` to a format string to indicate 37 padding bytes * removes the branches that amount to "give up on producing a valid format string if the struct is packed" * combines the resulting adjacent `if (isStruct) {`s now that neither is `if (isStruct && !isPacked) {` * invokes `_ctypes_alloc_format_padding` to add padding between structure fields, and after the last structure field. The computation used for the total size is unchanged from ctypes already used. This patch does not affect any existing aligment computation; all it does is use subtraction to deduce the amount of paddnig introduced by the existing code. --- Without this fix, it would never include padding bytes - an assumption that was only valid in the case when `_pack_` was set - and this case was explicitly not implemented. This should allow conversion from ctypes structs to numpy structs Fixes https://github.com/numpy/numpy/issues/10528
