New submission from Simon Depiets <sdepi...@gmail.com>: A couple of users have been having issues on console output since the Fall 2017 Creator Update on Windows 10
An OSError is triggered randomly when rewriting data on the console (typically with progress bars, for instance when you install a module with pip), this only happens with the Microsoft Console (within Powershell or cmd.exe). It seems the windows stdout console stream returns a length double what python expects. I don't have the skills to go deeper than the bufferedio.c method _bufferedwriter_raw_write to diagnostic the issue, so I've made a very dirty fix (which I do not recommend) https://github.com/python/cpython/compare/3.5...LlianeFR:patch-1 Different unrelated use cases where an error is triggered : https://stackoverflow.com/questions/47356993/oserror-raw-write-returned-invalid-length-when-using-print-in-python https://github.com/Microsoft/vscode/issues/39149 ---------- components: IO messages: 307811 nosy: Simon Depiets priority: normal severity: normal status: open title: OSError: raw write() returned invalid length on latest Win 10 Consoles type: behavior versions: Python 3.5 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue32245> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
