Ned Deily	7ae4112649	Issue #28676 : Prevent missing 'getentropy' declaration warning on macOS. Patch by Gareth Rees.	9 years ago
Victor Stinner	6d8bc46cc0	Catch EPERM error in py_getrandom() Issue #27955: Fallback on reading /dev/urandom device when the getrandom() syscall fails with EPERM, for example when blocked by SECCOMP.	9 years ago
Victor Stinner	af59732102	Cleanup random.c Issue #27955: modify py_getrnadom() and dev_urandom() * Add comments from Python 3.7 * PEP 7 style: add {...}	9 years ago
Victor Stinner	ec721f3305	py_getrandom(): use long type for the syscall() result Issue #27278. It should fix a conversion warning. In practice, the Linux kernel doesn't return more than 32 MB per call to the getrandom() syscall.	10 years ago
Victor Stinner	c72828ba33	cleanup random.c Casting Py_ssize_t to Py_ssize_t is useless.	10 years ago
Victor Stinner	b98a36e8f3	Fix os.urandom() using getrandom() on Linux Issue #27278: Fix os.urandom() implementation using getrandom() on Linux. Truncate size to INT_MAX and loop until we collected enough random bytes, instead of casting a directly Py_ssize_t to int.	10 years ago
Martin Panter	39b1025356	Fix typo and move comment to appropriate condition	10 years ago
Victor Stinner	dddf4849ec	os.urandom() doesn't block on Linux anymore Issue #26839: On Linux, os.urandom() now calls getrandom() with GRND_NONBLOCK to fall back on reading /dev/urandom if the urandom entropy pool is not initialized yet. Patch written by Colm Buckley.	10 years ago
Victor Stinner	9d24271d86	Fix os.urandom() on Solaris 11.3 Issue #26735: Fix os.urandom() on Solaris 11.3 and newer when reading more than 1,024 bytes: call getrandom() multiple times with a limit of 1024 bytes per call.	10 years ago
Serhiy Storchaka	fad85aadb0	Issue #25558 : Use compile-time asserts.	10 years ago
Victor Stinner	78cc2e8968	Issue #25003 : os.urandom() doesn't use getentropy() on Solaris because getentropy() is blocking, whereas os.urandom() should not block. getentropy() is supported since Solaris 11.3.	10 years ago
Victor Stinner	bae2d6203f	Issue #25003 : On Solaris 11.3 or newer, os.urandom() now uses the getrandom() function instead of the getentropy() function. The getentropy() function is blocking to generate very good quality entropy, os.urandom() doesn't need such high-quality entropy.	10 years ago
Victor Stinner	c51d244fc9	Issue #25171 : Fix compilation issue on OpenBSD in random.c Patch written by Remi Pointel.	10 years ago
Victor Stinner	3abf44e48f	Issue #25003 : On Solaris 11.3 or newer, os.urandom() now uses the getrandom() function instead of the getentropy() function. The getentropy() function is blocking to generate very good quality entropy, os.urandom() doesn't need such high-quality entropy.	10 years ago
Victor Stinner	61d5aab9b9	py_getrandom(): getrandom() can return EINTR See the latest version of getrandom() manual page: http://man7.org/linux/man-pages/man2/getrandom.2.html#NOTES The behavior when a call to getrandom() that is blocked while reading from /dev/urandom is interrupted by a signal handler depends on the initialization state of the entropy buffer and on the request size, buflen. If the entropy is not yet initialized, then the call will fail with the EINTR error. If the entropy pool has been initialized and the request size is large (buflen > 256), the call either succeeds, returning a partially filled buffer, or fails with the error EINTR. If the entropy pool has been initialized and the request size is small (buflen <= 256), then getrandom() will not fail with EINTR. Instead, it will return all of the bytes that have been requested. Note: py_getrandom() calls getrandom() with flags=0.	11 years ago
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	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

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	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
