# anvil-python -- CPython, cross-compiled for the printer.
#
# WHY THERE IS A SECOND PYTHON ON THIS MACHINE: FlashForge built its 3.8.2
# without _sqlite3, and that single omission is what pins MOONRAKER_VERSION to
# a 2023 commit.
#
# THE PREFIX IS COMPILED IN, exactly as for s6: sys.prefix and the stdlib
# search that follows are baked in at configure time, so moving the directory
# on the printer breaks the interpreter -- it has to be rebuilt, not renamed.
#
# ONLY bin/python3.13 SHIPS, and the name matters: anvil-env.sh PREPENDS
# $MODDIR/bin to PATH, so a bin/python3 of ours would sit AHEAD of
# FlashForge's for every process that sources it, and anything saying
# `python3` rather than "$FF_PYTHON" would silently change interpreter.

# NO Depends, AND THAT IS A MEASURED CLAIM. Every C library this interpreter
# uses is linked in STATICALLY, so the only shared objects it needs are the
# printer's own libc, libm, libdl, libpthread and libatomic.so.1, all on the
# stock rootfs.
PKG_DEPENDS=""

# SEVEN LIBRARIES, EACH EXACTLY ONE stdlib MODULE: openssl is _ssl and
# _hashlib, sqlite _sqlite3, zlib zlib, libffi _ctypes, xz _lzma, bzip2 _bz2,
# expat pyexpat. build.sh gates all seven by name, because CPython's answer to
# a library it cannot link is to record the module absent and CARRY ON.

# THE HEADERS ARE THE POINT OF THE DEV SPLIT. The eighteen python-* recipes
# cross-compile C extensions against them; before this package existed they
# reached them by building inside bin/payload.sh at the one moment an untrimmed
# staging tree happened to be on disk. A -dev package makes that durable, and
# a printer installs none of it.
#
# config-3.13-* comes along because sysconfig's LIBPL points into it.
# libpython3.13.a is deleted in build.sh: 35MB of archive nothing links.

PKG_DEV_DESCRIPTION="CPython headers and build configuration for mipsel. This is what the pkgs/3rdparty/python-* recipes compile their C extensions against; nothing installs it on a printer."

PKG_DESCRIPTION="CPython $PY_VERSION for the printer, with sqlite3, ssl, lzma, bz2, ctypes and expat linked in statically. Installs as bin/python3.13 -- never as python3, which would shadow the stock interpreter on PATH."
