* [3.12] gh-112088: Run autoreconf in GHA check_generated_files (GH-112090) ↵Victor Stinner2023-11-161-68/+68
| | | | | | | | | | | | | | | | | (#112159) gh-112088: Run autoreconf in GHA check_generated_files (#112090) The "Check if generated files are up to date" job of GitHub Actions now runs the "autoreconf -ivf -Werror" command instead of the "make regen-configure" command to avoid depending on the external quay.io server. Add Tools/build/regen-configure.sh script to regenerate the configure with an Ubuntu container image. The "quay.io/tiran/cpython_autoconf:271" container image (https://github.com/tiran/cpython_autoconf) is no longer used. (cherry picked from commit d9fd33a869d2be769ff596530f63ee099465b037)

* gh-101282: Apply BOLT optimizations to libpython for shared builds (#104709)Gregory Szorc2023-05-221-108/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Apply BOLT optimizations to libpython for shared builds. Most of the C code is in libpython so it is critical to apply BOLT there fully realize BOLT benefits. This change also reworks how BOLT instrumentation is applied. It effectively removes the readelf based logic added in gh-101525 and replaces it with a mechanism that saves a copy of the pre-bolt binary and restores that copy when necessary. This allows us to perform BOLT optimizations without having to manually delete the output binary to force a new bolt run. Also: - add a clean-bolt target for purging BOLT files and hook that up to the clean target - .gitignore BOLT related files Before and after this refactor, `make` will no-op after a previous run. Both versions should also share common make DAG deficiencies where targets fail to trigger as often as they need to or can trigger prematurely in certain scenarios. e.g. after this change you may need to `rm profile-bolt-stamp` to force a BOLT run because there aren't appropriate non-phony targets for BOLT's make target to depend on. To make it easier to iterate on custom BOLT settings, the flags to pass to instrumentation and application are now defined in configure and can be overridden by passing BOLT_INSTRUMENT_FLAGS and BOLT_APPLY_FLAGS.

* gh-99108: Import MD5 and SHA1 from HACL* (#102089)Jonathan Protzenko2023-02-221-2/+2

* gh-99108: Refactor _sha256 & _sha512 into _sha2. (#101924)Gregory P. Smith2023-02-161-69/+27
| | | | | | | | | This merges their code. They're backed by the same single HACL* static library, having them be a single module simplifies maintenance. This should unbreak the wasm enscripten builds that currently fail due to linking in --whole-archive mode and the HACL* library appearing twice. Long unnoticed error fixed: _sha512.SHA384Type was doubly assigned and was actually SHA512Type. Nobody depends on those internal names. Also rename LIBHACL_ make vars to LIBHACL_SHA2_ in preperation for other future HACL things.
* gh-99108: Import SHA2-384/512 from HACL* (#101707)Jonathan Protzenko2023-02-141-1/+1
| | | | | | Replace the builtin hashlib implementations of SHA2-384 and SHA2-512 originally from LibTomCrypt with formally verified, side-channel resistant code from the [HACL*](https://github.com/hacl-star/hacl-star/) project. The builtins remain a fallback only used when OpenSSL does not provide them.

* gh-99108: Replace SHA2-224 & 256 with verified code from HACL* (#99109)Jonathan Protzenko2023-02-071-1/+2
| | | | | | | | | | | | | | | | | | | | | | 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.
