New submission from Christian Heimes <li...@cheimes.de>:
As of today 3.11-dev requires Programs/_freeze_module to compile Python code to byte code. The dependency on an extra and special tool makes cross building more complicated. The _freeze_module is trivial and can be easily implemented in pure Python code. The re-introduction of _bootstrap_python helper would allow us to use a pure Python freeze_module for all modules except two importlib bootstrap modules. I have a proof of concept implementation that works for me. Proposal for standard builds: - Use Programs/_freeze_module to create Python/frozen_modules/importlib._bootstrap.h and Python/frozen_modules/importlib._bootstrap_external.h - build _bootstrap_python - use new tool "./_bootstrap_python Tools/scripts/freezemodule.py" to create remaining Python/frozen_modules/*.h Proposal for cross builds: - use user-provider Python interpreter (./configure --with-build-python) to generate all Python/frozen_modules/*.h with new freezemodule.py tool. When cross building the user must already provide a Python interpreter with same version and bytecode version as the build target. Users would no longer need to provide a _freeze_module binary with ./configure --with-freeze-module. ---------- assignee: christian.heimes components: Build, Cross-Build messages: 407459 nosy: Alex.Willmer, christian.heimes, gvanrossum priority: normal severity: normal status: open title: Provide pure-Python implementation of Programs/_freeze_module for cross building type: enhancement versions: Python 3.11 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue45949> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
