Victor Stinner e134a7fe36 Issue #23752: _Py_fstat() is now responsible to raise the Python exception
Add _Py_fstat_noraise() function when a Python exception is not welcome.

Victor Stinner 91afbb6088 Issue #23753: Move _Py_wstat() from Python/fileutils.c to Modules/getpath.c
I expected more users of _Py_wstat(), but in practice it's only used by
Modules/getpath.c. Move the function because it's not needed on Windows.
Windows uses PC/getpathp.c which uses the Win32 API (ex: GetFileAttributesW())
not the POSIX API.

Victor Stinner f329878e74 Issue #23753: Python doesn't support anymore platforms without stat() or
fstat(), these functions are always required.

Remove HAVE_STAT and HAVE_FSTAT defines, and stop supporting DONT_HAVE_STAT and
DONT_HAVE_FSTAT.

Victor Stinner a3c0202eb5 Issue #23708: Save/restore errno in _Py_read() and _Py_write()
Save and then restore errno because PyErr_CheckSignals() and
PyErr_SetFromErrno() can modify it.

Victor Stinner 7f04d4d4b7 Issue #23708: Split assertion expression in two assertions in _Py_read() and
_Py_write() to know which test failed on the buildbot "AMD64 Snow Leop 3.x".

Victor Stinner c1cf4f7ef9 Issue #23708: Fix _Py_read() compilation error on Windows
Fix typo: self->fd => fd
2015-03-19 23:53:04 +01:00
Victor Stinner 66aab0c4b5 Issue #23708: Add _Py_read() and _Py_write() functions to factorize code handle
EINTR error and special cases for Windows.

These functions now truncate the length to PY_SSIZE_T_MAX to have a portable
and reliable behaviour. For example, read() result is undefined if counter is
greater than PY_SSIZE_T_MAX on Linux.

Victor Stinner a47fc5c2dd Issue #23694: Handle EINTR in _Py_open() and _Py_fopen_obj()
Retry open()/fopen() if it fails with EINTR and the Python signal handler
doesn't raise an exception.

Victor Stinner e42ccd2bfd Issue #23694: Enhance _Py_fopen(), it now raises an exception on error
* If fopen() fails, OSError is raised with the original filename object.
* The GIL is now released while calling fopen()

Victor Stinner a555cfcb73 Issue #23694: Enhance _Py_open(), it now raises exceptions
* _Py_open() now raises exceptions on error. If open() fails, it raises an
  OSError with the filename.
* _Py_open() now releases the GIL while calling open()
* Add _Py_open_noraise() when _Py_open() cannot be used because the GIL is not
  held

Steve Dower f2f373f593 Issue #23152: Implement _Py_fstat() to support files larger than 2 GB on Windows.
fstat() may fail with EOVERFLOW on files larger than 2 GB because the file size type is an signed 32-bit integer.

Victor Stinner 282124b8c4 Closes #22258: Fix the the internal function set_inheritable() on Illumos.
This platform exposes the function ioctl(FIOCLEX), but calling it fails with
errno is ENOTTY: "Inappropriate ioctl for device". set_inheritable() now falls
back to the slower fcntl() (F_GETFD and then F_SETFD).

ASCII/surrogateescape codec is now used, instead of the locale encoding, to
decode the command line arguments. This change fixes inconsistencies with
os.fsencode() and os.fsdecode() because these operating systems announces an
ASCII locale encoding, whereas the ISO-8859-1 encoding is used in practice.

Victor Stinner af02e1c85a Add PyUnicode_DecodeLocaleAndSize() and PyUnicode_DecodeLocale()
* PyUnicode_DecodeLocaleAndSize() and PyUnicode_DecodeLocale() decode a string
   from the current locale encoding
 * _Py_char2wchar() writes an "error code" in the size argument to indicate
   if the function failed because of memory allocation failure or because of a
   decoding error. The function doesn't write the error message directly to
   stderr.
 * Fix time.strftime() (if wcsftime() is missing): decode strftime() result
   from the current locale encoding, not from the filesystem encoding.

Victor Stinner 168e117e0a Add an optional size argument to _Py_char2wchar()

an option to get it.
