From 4de7457009d3dac9c93cc5b471d20a8d5e92ff33 Mon Sep 17 00:00:00 2001 From: Antoine Pitrou Date: Sat, 9 Feb 2013 23:11:27 +0100 Subject: Issue #17173: Remove uses of locale-dependent C functions (isalpha() etc.) in the interpreter. I've left a couple of them in: zlib (third-party lib), getaddrinfo.c (doesn't include Python.h, and probably obsolete), _sre.c (legitimate use for the re.LOCALE flag). --- Misc/NEWS | 3 +++ Modules/_struct.c | 4 ++-- Modules/binascii.c | 2 +- Modules/posixmodule.c | 2 +- Modules/socketmodule.c | 2 +- Objects/longobject.c | 4 ++-- Objects/stringlib/formatter.h | 2 +- Python/ast.c | 2 +- Python/dynload_aix.c | 3 +-- Python/getargs.c | 6 +++--- Python/mystrtoul.c | 6 +++--- 11 files changed, 19 insertions(+), 17 deletions(-) diff --git a/Misc/NEWS b/Misc/NEWS index a24b3de..8fe5e16 100644 --- a/Misc/NEWS +++ b/Misc/NEWS @@ -10,6 +10,9 @@ What's New in Python 3.2.4 Core and Builtins ----------------- +- Issue #17173: Remove uses of locale-dependent C functions (isalpha() etc.) + in the interpreter. + - Issue #17043: The unicode-internal decoder no longer read past the end of input buffer. diff --git a/Modules/_struct.c b/Modules/_struct.c index edbe9b9..3f20518 100644 --- a/Modules/_struct.c +++ b/Modules/_struct.c @@ -1184,7 +1184,7 @@ prepare_s(PyStructObject *self) size = 0;
