Steve Dower 8fc8980c96 Issue #23524: Replace _PyVerify_fd function with calls to _set_thread_local_invalid_parameter_handler. 2015-04-12 00:26:27 -04:00
Victor Stinner 82c3e4599d Issue #23836: Add _Py_write_noraise() function
Helper to write() which retries write() if it is interrupted by a signal (fails
with EINTR).

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 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 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 d81431f587 Issue #23524: Replace _PyVerify_fd function with calling _set_thread_local_invalid_parameter_handler on every thread. 2015-03-06 14:47:02 -08:00
Serhiy Storchaka 06a13f81ea Issue #23152: Move declarations back to posixmodule.c.
Declarations of Windows-specific auxilary functions need Windows types
from windows.h.  Instead of including windows.h in Python.h and making
it available to all Windows users, it is simpler and safer just move
declarations to the single file that needs them.

Serhiy Storchaka 12ebbc74f1 Issue #23152: Move declaration into a header and exclude from stable API. 2015-02-22 19:39:36 +02:00
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 f6a271ae98 Issue #18395: Rename ``_Py_char2wchar()`` to :c:func:`Py_DecodeLocale`, rename
``_Py_wchar2char()`` to :c:func:`Py_EncodeLocale`, and document these
functions.

Victor Stinner 1db9e7bb19 Issue #22054: Add os.get_blocking() and os.set_blocking() functions to get and
set the blocking mode of a file descriptor (False if the O_NONBLOCK flag is
set, True otherwise). These functions are not available on Windows.

Martin v. Löwis 1c0689c613 Issue #19526: Exclude all new API from the stable ABI. 2014-01-03 21:36:49 +01:00
Victor Stinner daf455554b Issue #18571: Implementation of the PEP 446: file descriptors and file handles
are now created non-inheritable; add functions os.get/set_inheritable(),
os.get/set_handle_inheritable() and socket.socket.get/set_inheritable().

Brett Cannon efb00c0cc1 Issue #14153 Create _Py_device_encoding() to prevent _io from having to import
the os module.

Victor Stinner 2f02a51135 PyUnicode_EncodeFS() raises an exception if _Py_wchar2char() fails
* Add error_pos optional argument to _Py_wchar2char()
 * PyUnicode_EncodeFS() raises a UnicodeEncodeError or MemoryError if
   _Py_wchar2char() fails

Victor Stinner 168e117e0a Add an optional size argument to _Py_char2wchar()
_Py_char2wchar() callers usually need the result size in characters. Since it's
trivial to compute it in _Py_char2wchar() (O(1) whereas wcslen() is O(n)), add
an option to get it.

Victor Stinner 015f4d87ab _Py_wrealpath() requires the size of the output buffer 2010-10-07 22:29:53 +00:00
Victor Stinner a4a759515e _Py_stat() and _Py_fopen(): avoid PyUnicode_AsWideCharString() on Windows
On Windows, Py_UNICODE is wchar_t, so we can avoid the expensive Py_UNICODE*
=> wchar_t* conversion.

Victor Stinner b306d7594f Fix fileutils for Windows
* Don't define _Py_wstat() on Windows, Windows has its own _wstat() function
   with a different API (the stat buffer has another type)
 * Include windows.h
2010-10-07 22:09:40 +00:00
Victor Stinner 4e31443c4d Create fileutils.c/.h
* _Py_fopen() and _Py_stat() come from Python/import.c
 * (_Py)_wrealpath() comes from Python/sysmodule.c
 * _Py_char2wchar(), _Py_wchar2char() and _Py_wfopen() come from Modules/main.c
 * (_Py)_wstat(), (_Py)_wgetcwd(), _Py_wreadlink() come from Modules/getpath.c
