+Subject: [PATCH] bpo-36302: Sort list of sources
+
+when building packages (e.g. for openSUSE Linux)
+(random) filesystem order of input files
+influences ordering of functions in the output .so files.
+Thus without the patch, builds (in disposable VMs) would usually differ.
+
+Without this patch, all callers have to be patched individually
+https://github.com/dugsong/libdnet/pull/42
+https://github.com/sass/libsass-python/pull/212
+https://github.com/tahoe-lafs/pycryptopp/pull/41
+https://github.com/yt-project/yt/pull/2206
+https://github.com/pyproj4/pyproj/pull/142
+https://github.com/pytries/datrie/pull/49
+https://github.com/Roche/pyreadstat/pull/37
+but that is an infinite effort.
+
+See https://reproducible-builds.org/ for why this matters.
