Łukasz Langa <luk...@langa.pl> added the comment: Hynek confirmed on Big Sur with Python 3.9.5 from asdf that test_input_tty hangs, too, if ran for the second time in the same process.
Moreover, readline is not it. First of all, it's libedit on macOS: ❯ ll /usr/lib/libreadline.dylib lrwxr-xr-x 1 root wheel 15B Feb 2 2020 /usr/lib/libreadline.dylib -> libedit.3.dylib So Python uses that by default: >>> import readline >>> readline._READLINE_LIBRARY_VERSION 'EditLine wrapper' >>> readline._READLINE_RUNTIME_VERSION 1026 >>> readline._READLINE_VERSION 1026 Unless you instruct it to use readline (for example by providing "-I$(brew --prefix readline)/include" to CFLAGS and "-L$(brew --prefix readline)/lib" to LDFLAGS before running ./configure): >>> import readline >>> readline._READLINE_LIBRARY_VERSION '8.1' >>> readline._READLINE_RUNTIME_VERSION 2049 >>> readline._READLINE_VERSION 2049 The hang is the same in both cases. Next course of action, checking if it's not due to fork shenanigans in _run_child(): https://github.com/python/cpython/blob/1841c70f2bdab9d29c1c74a8afffa45d5555af98/Lib/test/test_builtin.py#L2001 ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue44887> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
