From 4827483f47906fecee6b5d9097df2a69a293a85c Mon Sep 17 00:00:00 2001 From: Inada Naoki Date: Mon, 29 Mar 2021 12:28:14 +0900 Subject: bpo-43510: Implement PEP 597 opt-in EncodingWarning. (GH-19481) See [PEP 597](https://www.python.org/dev/peps/pep-0597/). * Add `-X warn_default_encoding` and `PYTHONWARNDEFAULTENCODING`. * Add EncodingWarning * Add io.text_encoding() * open(), TextIOWrapper() emits EncodingWarning when encoding is omitted and warn_default_encoding is enabled. * _pyio.TextIOWrapper() uses UTF-8 as fallback default encoding used when failed to import locale module. (used during building Python) * bz2, configparser, gzip, lzma, pathlib, tempfile modules use io.text_encoding(). * What's new entry --- Python/sysmodule.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'Python/sysmodule.c') diff --git a/Python/sysmodule.c b/Python/sysmodule.c index 686b6cae3b..54d70ef056 100644 --- a/Python/sysmodule.c +++ b/Python/sysmodule.c @@ -2514,6 +2514,7 @@ static PyStructSequence_Field flags_fields[] = { {"isolated", "-I"}, {"dev_mode", "-X dev"}, {"utf8_mode", "-X utf8"}, + {"warn_default_encoding", "-X warn_default_encoding"}, {0} }; @@ -2521,7 +2522,7 @@ static PyStructSequence_Desc flags_desc = { "sys.flags", /* name */ flags__doc__, /* doc */ flags_fields, /* fields */ - 15 + 16 }; static int @@ -2560,6 +2561,7 @@ set_flags_from_config(PyInterpreterState *interp, PyObject *flags) SetFlag(config->isolated); SetFlagObj(PyBool_FromLong(config->dev_mode)); SetFlag(preconfig->utf8_mode); + SetFlag(config->warn_default_encoding); #undef SetFlagObj #undef SetFlag return 0; -- cgit v1.2.1
