#23164 find_interpreter fragile across Python minor versions Issue created by cburroughs See pex-tool/pex#3113 for background In https://github.com/pantsbuild/pants/blob/2804a4673f/src/python/pants/backend/python/util_rules/pex.py#L386-L430 we hash the

python

binary, but that is not actually guaranteed to change across minor versions (So Python More generally in https://github.com/pantsbuild/pants/blob/2804a4673f/src/python/pants/core/util_rules/system_binaries.py#L110 we generally assume that the binary only changes if something like the output of

--version

changes, but that is not true in the face of dynamic linking. Ex

awk

isn't just

awk

but:

$ ldd /usr/bin/awk
	linux-vdso.so.1 (0x00007f9513b81000)
	libreadline.so.8 => /usr/lib64/libreadline.so.8 (0x00007f9513a11000)
	libmpfr.so.6 => /usr/lib64/libmpfr.so.6 (0x00007f9513955000)
	libgmp.so.10 => /usr/lib64/libgmp.so.10 (0x00007f95138ad000)
	libm.so.6 => /usr/lib64/libm.so.6 (0x00007f95137ef000)
	libc.so.6 => /usr/lib64/libc.so.6 (0x00007f9513624000)
	libtinfow.so.6 => /usr/lib64/libtinfow.so.6 (0x00007f95135e9000)
	/lib64/ld-linux-x86-64.so.2 (0x00007f9513b83000)

In the "extreme" python case from the linked issue, almost all of the code is in the

.so

files, not the "binary". pantsbuild/pants
