Zero PRs were merged this week, with 30 additional commits landing in the CPython repository.
Starting with new features, the Python REPL received substantial enhancements. Loïc Simon implemented auto-complete functionality for module attributes in import statements, making interactive development more efficient. Antonio Cuni integrated fancycompleter to provide colored tab completions in the new REPL,…
Moving to performance and infrastructure improvements, Pablo Galindo Salgado addressed two critical issues. First, he fixed a huge page leak in the datastack chunk allocator by moving rounding logic into the virtual memory allocator functions, ensuring proper cleanup across all virtual memory users including the JIT…
Serhiy Storchaka enhanced the Base32 and Base64 codecs by adding optional padding support. The binascii and base64 modules now include a padded parameter that controls padding behavior in both encoding and decoding functions. Notably, base64.urlsafe_b64decode no longer requires padding by default.
On the optimization front, Donghee Na improved constant folding in…
