Victor Stinner ce6aa749b4 Make _PyTime_RoundHalfEven() private again 2015-09-09 22:28:09 +02:00
Victor Stinner 7667f58151 Issue #23517: fromtimestamp() and utcfromtimestamp() methods of 
datetime.datetime now round microseconds to nearest with ties going to nearest
even integer (ROUND_HALF_EVEN), as round(float), instead of rounding towards
-Infinity (ROUND_FLOOR).

pytime API: replace _PyTime_ROUND_HALF_UP with _PyTime_ROUND_HALF_EVEN. Fix
also _PyTime_Divide() for negative numbers.

_PyTime_AsTimeval_impl() now reuses _PyTime_Divide() instead of reimplementing
rounding modes.

Victor Stinner 6fb5bae252 Fix race condition in create_stdio() 
Issue #24891: Fix a race condition at Python startup if the file descriptor
of stdin (0), stdout (1) or stderr (2) is closed while Python is creating
sys.stdin, sys.stdout and sys.stderr objects. These attributes are now set
to None if the creation of the object failed, instead of raising an OSError
exception. Initial patch written by Marco Paolini.

forgot to rename it.

Victor Stinner c3c616c3d1 Issue #24707: Remove assertion in monotonic clock 
Don't check anymore at runtime that the monotonic clock doesn't go backward.
Yes, it happens. It occurs sometimes each month on a Debian buildbot slave
running in a VM.

The problem is that Python cannot do anything useful if a monotonic clock goes
backward. It was decided in the PEP 418 to not fix the system, but only expose
the clock provided by the OS.

integer (ROUND_HALF_EVEN).

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.
