Victor Stinner	9aa1331c6f	Issue #22585 : os.urandom() now releases the GIL when the getentropy() is used (OpenBSD 5.6+).	11 years ago
Victor Stinner	79b74aeb20	Issue #22181 : os.urandom() now releases the GIL when the getrandom() implementation is used.	11 years ago
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.	11 years ago
Victor Stinner	c9382eb7ae	Issue #23707 : On UNIX, os.urandom() now calls the Python signal handler when read() is interrupted by a signal. dev_urandom_python() now calls _Py_read() helper instead of calling directly read().	11 years ago
Victor Stinner	c7cd12da60	Issue #22181 : Fix dev_urandom_noraise(), try calling py_getrandom() before opening /dev/urandom.	11 years ago
Victor Stinner	9eb57c5fa5	Issue #22181 : The availability of the getrandom() is now checked in configure, and stored in pyconfig.h as the new HAVE_GETRANDOM_SYSCALL define. Fix os.urandom() tests using file descriptors if os.urandom() uses getrandom().	11 years ago
Victor Stinner	59f7fb29ec	Issue #22181 : On Linux, os.urandom() now uses the new getrandom() syscall if 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.	11 years ago
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	11 years ago
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.	11 years ago
Victor Stinner	fe02e39029	Issue #22585 : On OpenBSD 5.6 and newer, os.urandom() now calls getentropy(), instead of reading /dev/urandom, to get pseudo-random bytes.	11 years ago
Victor Stinner	4d6a3d6c01	Issue #22585 : On OpenBSD 5.6 and newer, os.urandom() now calls getentropy(), instead of reading /dev/urandom, to get pseudo-random bytes.	11 years ago

Antoine Pitrou	e472aeafc3	Issue #21207 : Detect when the os.urandom cached fd has been closed or replaced, and open it anew.	12 years ago

Christian Heimes	985ecdcfc2	ssue #19183 : Implement PEP 456 'secure and interchangeable hash algorithm'. Python now uses SipHash24 on all major platforms.	12 years ago
Victor Stinner	0c083461a5	Fix compiler warning in win32_urandom(): explicit cast to DWORD in CryptGenRandom()	12 years ago
Georg Brandl	c6a2c9b466	Closes #15213 : update comment for _PyOS_URandom	12 years ago
Antoine Pitrou	4879a963d4	Issue #18756 : os.urandom() now uses a lazily-opened persistent file descriptor, so as to avoid using many file descriptors when run in parallel from multiple threads.	13 years ago
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().	13 years ago
Antoine Pitrou	ec34ab5010	Issue #18756 : Improve error reporting in os.urandom() when the failure is due to something else than /dev/urandom not existing.	13 years ago
Martin v. Löwis	3f50bf652b	Drop support for Windows 2000; allow any XP API (but not Vista+). Drop SDK version configuration for Tk compilation, to not bind it to W2k anymore. Binding it to XP would conflict with Tk's own binding of tkMenu to W2k.	13 years ago
Antoine Pitrou	e299cae230	Issue #15340 : Fix importing the random module when /dev/urandom cannot be opened. This was a regression caused by the hash randomization patch.	14 years ago

Barry Warsaw	1e13eb084f	- Issue #13703 : oCERT-2011-003: add -R command-line option and PYTHONHASHSEED environment variable, to provide an opt-in way to protect against denial of service attacks due to hash collisions within the dict and set types. Patch by David Malcolm, based on work by Victor Stinner.	14 years ago
Georg Brandl	91e5c08fe8	Fix typo in conditional.	14 years ago
Georg Brandl	12897d7d39	Fix typo in conditional.	14 years ago
Georg Brandl	2daf6ae249	Issue #13703 : add a way to randomize the hash values of basic types (str, bytes, datetime) in order to make algorithmic complexity attacks on (e.g.) web apps much more complicated. The environment variable PYTHONHASHSEED and the new command line flag -R control this behavior.	14 years ago
