Ideally, I would prefer to raise an EOFError if decompress() is called after end-of-stream is reached (for consistency with BZ2Decompressor). However, accumulating the data in unused_data is closer to being backward- compatible, so it's probably the better approach to take. ---------- components: Library (Lib) files: zlib_unused_data_test.py messages: 174056 nosy: amaury.forgeotdarc, nadeem.vawda priority: normal severity: normal stage: needs patch status: open title: zlib.Decompress.decompress() after EOF discards existing value of unused_data type: behavior versions: Python 2.7, Python 3.2, Python 3.3, Python 3.4 Added file: http://bugs.python.org/file27767/zlib_unused_data_test.py _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue16350> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
