From fc889c48edc17b9502c0aef416ce2d003dbef4e6 Mon Sep 17 00:00:00 2001 From: Brian Curtin Date: Sun, 28 Nov 2010 23:59:46 +0000 Subject: Fix for #8879. Amaury noticed that this was originally written in a way that would fail on names that can't be encoded with the mbcs codec. Restructured the function to work with wide names first then narrow names second, to fall in line with the way other functions are written in posixmodule.c. --- Lib/test/test_os.py | 5 +++++ Modules/posixmodule.c | 20 ++++++++++++++++++-- 2 files changed, 23 insertions(+), 2 deletions(-) diff --git a/Lib/test/test_os.py b/Lib/test/test_os.py index 978364c..5a37522 100644 --- a/Lib/test/test_os.py +++ b/Lib/test/test_os.py @@ -887,6 +887,11 @@ class LinkTests(unittest.TestCase): self._test_link(bytes(self.file1, sys.getfilesystemencoding()), bytes(self.file2, sys.getfilesystemencoding())) + def test_mbcs_name(self): + self.file1 += "\u65e5\u672c" + self.file2 = self.file1 + "2" + self._test_link(self.file1, self.file2) + if sys.platform != 'win32': class Win32ErrorTests(unittest.TestCase): pass diff --git a/Modules/posixmodule.c b/Modules/posixmodule.c index 3197a0d..48dbaa5 100644 --- a/Modules/posixmodule.c +++ b/Modules/posixmodule.c @@ -2252,6 +2252,22 @@ win32_link(PyObject *self, PyObject *args) char *src, *dst; BOOL rslt; + PyUnicodeObject *usrc, *udst; + if (PyArg_ParseTuple(args, "UU:link", &usrc, &udst)) { + Py_BEGIN_ALLOW_THREADS + rslt = CreateHardLinkW(PyUnicode_AS_UNICODE(udst), + PyUnicode_AS_UNICODE(usrc), NULL); + Py_END_ALLOW_THREADS + + if (rslt == 0) + return win32_error("link", NULL); + + Py_RETURN_NONE; + } + + /* Narrow strings also valid. */ + PyErr_Clear(); + if (!PyArg_ParseTuple(args, "O&O&:link", PyUnicode_FSConverter, &osrc, PyUnicode_FSConverter, &odst)) return NULL; @@ -2260,13 +2276,13 @@ win32_link(PyObject *self, PyObject *args) dst = PyBytes_AsString(odst); Py_BEGIN_ALLOW_THREADS - rslt = CreateHardLink(dst, src, NULL); + rslt = CreateHardLinkA(dst, src, NULL); Py_END_ALLOW_THREADS Py_DECREF(osrc); Py_DECREF(odst); if (rslt == 0) - return posix_error(); + return win32_error("link", NULL); Py_RETURN_NONE; } -- cgit v0.12
