Author: frutiger Date: Sat Oct 21 09:13:41 2017 New Revision: 316264 URL: http://llvm.org/viewvc/llvm-project?rev=316264&view=rev Log: [bindings] allow null strings in Python 3
Some API calls accept 'NULL' instead of a char array (e.g. the second argument to 'clang_ParseTranslationUnit'). For Python 3 compatibility, all strings are passed through 'c_interop_string' which expects to receive only 'bytes' or 'str' objects. This change extends this behavior to additionally allow 'None' to be supplied. A test case was added which breaks in Python 3, and is fixed by this change. All the test cases pass in both, Python 2 and Python 3.
