+Subject: [PATCH] plugins/python: use Py_CompileString
+
+Instead of the deprecated PyParser_SimpleParseString, PyParser_SimpleParseFile
+and PyNode_Compile.
+While at it fixup a possible null pointer dereference when uwsgi_open_and_read
+returns an empty string.
+
+See https://bugs.python.org/issue40939
