* gh-99108: Replace SHA2-224 & 256 with verified code from HACL* (#99109)Jonathan Protzenko2023-02-06
| | | | | | | | | | | | | | | | | | | | | | 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: Add a Test to Verify GILState Matches the "Current" Thread State ↵Eric Snow2023-02-06

* gh-76961: Fix buildbot failures in test_pep3118 (#101587)Mark Dickinson2023-02-06
| | | This PR fixes the buildbot failures introduced by the merge of #5561, by restricting the relevant tests to something that should work on both 32-bit and 64-bit platforms. It also silences some compiler warnings introduced in that PR.

* gh-101334: Don't force USTAR format in test_tarfile. (GH-101572)Gregory P. Smith2023-02-05
| | | | | That causes the test to fail when run using a high UID as that ancient format cannot represent it. The current default (PAX) and the old default (GNU) both support high UIDs.

* gh-76961: Fix the PEP3118 format string for ctypes.Structure (#5561)Eric Wieser2023-02-05
| | | | | | | | | | | | | | | | | | | | 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

* gh-101266: Fix __sizeof__ for subclasses of int (#101394)Mark Dickinson2023-02-05
| | | | | | | Fix the behaviour of the `__sizeof__` method (and hence the results returned by `sys.getsizeof`) for subclasses of `int`. Previously, `int` subclasses gave identical results to the `int` base class, ignoring the presence of the instance dictionary. <!-- gh-issue-number: gh-101266 --> * Issue: gh-101266 <!-- /gh-issue-number -->

* gh-84559: Remove the new multiprocessing warning, too disruptive. (#101551)Gregory P. Smith2023-02-03

* GH-84559: Deprecate fork being the multiprocessing default. (#100618)Gregory P. Smith2023-02-02
| | | | | | | | This starts the process. Users who don't specify their own start method and use the default on platforms where it is 'fork' will see a DeprecationWarning upon multiprocessing.Pool() construction or upon multiprocessing.Process.start() or concurrent.futures.ProcessPool use. See the related issue and documentation within this change for details.

* gh-99952: [ctypes] fix refcount issues in from_param() result. (#100169)Yukihiro Nakadaira2023-01-26
| | | | | Fixes a reference counting issue with `ctypes.Structure` when a `from_param()` method call is used and the structure size is larger than a C pointer `sizeof(void*)`. This problem existed for a very long time, but became more apparent in 3.8+ by change likely due to garbage collection cleanup timing changes.

| | | | | | | When testing element truth values, emit a DeprecationWarning in all implementations. This had emitted a FutureWarning in the rarely used python-only implementation since ~2.7 and has always been documented as a behavior not to rely on. Matching an element in a tree search but having it test False can be unexpected. Raising the warning enables making the choice to finally raise an exception for this ambiguous behavior in the future.
