Worked on the astral-sh/python-build-standalone repository to enhance build reliability and portability by integrating the Hacl_Hash_SHA2 cryptographic component directly into the Python extension. This approach involved updating the build system configuration, specifically modifying extension-modules.yml written in YAML, to compile Hacl_Hash_SHA2.c within the extension itself rather than linking against an external libHacl_Hash_SHA2.a library. By removing the external linkage, the work reduced dependency complexity, minimized potential ABI mismatches, and improved consistency across different environments. The changes streamlined continuous integration processes and ensured that the extension could be built and deployed more easily across varied platforms.
