* | Issue #23752: _Py_fstat() is now responsible to raise the Python exceptionVictor Stinner2015-03-301-2/+1
| | | | | | | | Add _Py_fstat_noraise() function when a Python exception is not welcome.

| | | | | | | | | | | | | | read() is interrupted by a signal. dev_urandom_python() now calls _Py_read() helper instead of calling directly read().

| | | | | | | | | | | | and stored in pyconfig.h as the new HAVE_GETRANDOM_SYSCALL define. Fix os.urandom() tests using file descriptors if os.urandom() uses getrandom().

| | | | | | | | | | | | available, syscall introduced in the Linux kernel 3.17. It is more reliable and more secure, because it avoids the need of a file descriptor and waits until the kernel has enough entropy.
* | Issue #23694: Enhance _Py_open(), it now raises exceptionsVictor Stinner2015-03-181-7/+3
| | | | | | | | | | | | | | | | * _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

| | | | | | | | | | | | Windows. fstat() may fail with EOVERFLOW on files larger than 2 GB because the file size type is an signed 32-bit integer.
