In discussing #15216, I noticed that the write_through parameter is completely unused in the Python implementation of TextIOWrapper. That also means we have a hole in the test coverage: there is no test that is run on both the C and Python versions to ensure that the data is being written directly through to the underlying buffer (e.g. by passing in a mock buffer object). |

The fact that the Python implementation doesn't look at write_through doesn't necessarily mean that it's not respected. It could always write through. Indeed, it looks like this is the case and was discussed at one point: http://bugs.python.org/issue12591#msg141006 Also, it appears that there is a test in both cases (the test class is subclassed twice), though I could be wrong: http://hg.python.org/cpython/file/0eeffeadaa1e/Lib/test/test_io.py#l2453 In any case, this could probably at least use a code comment. |

Ah, thanks. Yes, that could definitely use a comment :) |
