Source: blockdiag Version: 1.5.3+dfsg-5.1 Severity: grave Tags: patch Hi,
Trying to build nova 17.0.0~rc1's sphinx doc with python3-blockdiag, I get: File "/usr/lib/python3/dist-packages/blockdiag/utils/compat.py", line 39, in <lambda> return lambda stream, *args: getreader(encoding)(stream.buffer, *args) AttributeError: '_io.BufferedRandom' object has no attribute 'buffer' Indeed, the upstream code fix for Python 3 for blockdiag is simply wrong. There's no such thing as _io.BufferedRandom.buffer. The patch should go like this: --- /usr/lib/python3/dist-packages/blockdiag/utils/compat.py.orig 2018-02-15 13:39:46.846727862 +0000 +++ /usr/lib/python3/dist-packages/blockdiag/utils/compat.py 2018-02-15 13:11:21.125447664 +0000 @@ -36,7 +36,7 @@ getreader = codecs.getreader def py3_getreader(encoding): - return lambda stream, *args: getreader(encoding)(stream.buffer, *args) + return lambda stream, *args: getreader(encoding)(stream, *args) codecs.getreader = py3_getreader
