Subject: [PATCH] Replace not predictable build path prefix with hardcode
string in the generated output file
The build path may contain tmp dir which is not predictable, it caused
the generated output file is not stable at each build and made
the generated library is not reproducible [1] between builds
vim frozenlist/_frozenlist.cpp
...
/* BEGIN: Cython Metadata
{
"distutils": {
"depends": [],
"language": "c++",
"name": "frozenlist._frozenlist",
"sources": [
"/tmp/.tmp-frozenlist-pep517-cfdvygni/src/frozenlist/_frozenlist.pyx"
]
},
"module_name": "frozenlist._frozenlist"
}
END: Cython Metadata */
...
Replace build path prefix with hardcode `build_path', it is no harm to
tweak comments in source file, after applied this commit,
vim frozenlist/_frozenlist.cpp
...
/* BEGIN: Cython Metadata
{
"distutils": {
"depends": [],

]
},
"module_name": "frozenlist._frozenlist"
}
END: Cython Metadata */
