| * Issue #25003: os.urandom() doesn't use getentropy() on Solaris becauseVictor Stinner2015-10-011-4/+8
| | | | | | | | | | getentropy() is blocking, whereas os.urandom() should not block. getentropy() is supported since Solaris 11.3.

| | | | | | | | | | | | 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.
* | py_getrandom(): getrandom() *can* return EINTRVictor Stinner2015-07-301-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
