Kubilay Kocak <[email protected]> added the comment:
For FreeBSD Python language ports, the change doesn't have a big negative
impact for the Python language/interpreter ports themselves
We have the following block in lang/python3? ports:
.if ${PORT_OPTIONS:MPYMALLOC}
ABIFLAGS:= m${ABIFLAGS}
.endif
.if ${PORT_OPTIONS:MDEBUG}
ABIFLAGS:= d${ABIFLAGS}
.endif
We then use the variable to substitute the correct suffix into the pkg-plist
items:
.if !empty(ABIFLAGS)
PLIST_FILES+= bin/python${PYTHON_VER}${ABIFLAGS} \
bin/python${PYTHON_VER}${ABIFLAGS}-config \
libdata/pkgconfig/python-${PYTHON_VER}${ABIFLAGS}.pc
<snip>
${INSTALL_DATA} ${WRKSRC}/Tools/gdb/libpython.py \
${STAGEDIR}${PREFIX}/lib/libpython${PYTHON_VER}${ABIFLAGS}.so.1.0-gdb.py
One question I have is, can/does SOABI flag removal affect any third party
package/extension builds in any way, particularly affecting the names of files
they produce?
We have a ton of python packages/extensions in the ports tree, so anything that
affected their builds, particularly when it comes to setuptools --record output
changes, would be a blocker for supporting 3.8
For example, we had to produce custom ports framework code to account for
PEP488 [1] and PEP3147 [2] filename suffixes, for these filename differences,
which was painful at the time:
# PEP 0488 (https://www.python.org/dev/peps/pep-0488/)
.if ${PYTHON_REL} < 3500
PYTHON_PYOEXTENSION= pyo
.else
PYTHON_PYOEXTENSION= opt-1.pyc
.endif
.if ${PYTHON_REL} >= 3200 && defined(_PYTHON_FEATURE_PY3KPLIST)
# When Python version is 3.2+ we rewrite all the filenames
# of TMPPLIST that end with .py[co], so that they conform
# to PEP 3147 (see https://www.python.org/dev/peps/pep-3147/)
