Benjamin Peterson af580dff4a replace PY_LONG_LONG with long long 2016-09-06 10:46:49 -07:00
Victor Stinner ad8c83ad6b Avoid inefficient way to call functions without argument
Don't pass "()" format to PyObject_CallXXX() to call a function without
argument: pass NULL as the format string instead. It avoids to have to parse a
string to produce 0 argument.

Victor Stinner 84ff4abd79 Merge 3.4 (datetime rounding) 2015-09-18 14:50:18 +02:00
Victor Stinner 511491ade0 Issue #23517: Fix rounding in fromtimestamp() and utcfromtimestamp() methods
of datetime.datetime: microseconds are now rounded to nearest with ties going
to nearest even integer (ROUND_HALF_EVEN), instead of being rounding towards
zero (ROUND_DOWN). It's important that these methods use the same rounding
mode than datetime.timedelta to keep the property:

   (datetime(1970,1,1) + timedelta(seconds=t)) == datetime.utcfromtimestamp(t)

It also the rounding mode used by round(float) for example.

Add more unit tests on the rounding mode in test_datetime.

Victor Stinner 9a8b177e60 Issue #25155: Add _PyTime_AsTimevalTime_t() function
On Windows, the tv_sec field of the timeval structure has the type C long,
whereas it has the type C time_t on all other platforms. A C long has a size of
32 bits (signed inter, 1 bit for the sign, 31 bits for the value) which is not
enough to store an Epoch timestamp after the year 2038.

Add the _PyTime_AsTimevalTime_t() function written for datetime.datetime.now():
convert a _PyTime_t timestamp to a (secs, us) tuple where secs type is time_t.
It allows to support dates after the year 2038 on Windows.

Enhance also _PyTime_AsTimeval_impl() to detect overflow on the number of
seconds when rounding the number of microseconds.

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 a53ec7a91a Backed out changeset b690bf218702
Issue #23517: the change broke test_datetime. datetime.timedelta() rounding
mode must also be changed, and test_datetime must be updated for the new
rounding mode (half up).

Larry Hastings 2623c8c23c Issue #20530: Argument Clinic's signature format has been revised again.
The new syntax is highly human readable while still preventing false
positives.  The syntax also extends Python syntax to denote "self" and
positional-only parameters, allowing inspect.Signature objects to be
totally accurate for all supported builtins in Python 3.4.

Larry Hastings 581ee3618c Issue #20326: Argument Clinic now uses a simple, unique signature to
annotate text signatures in docstrings, resulting in fewer false
positives.  "self" parameters are also explicitly marked, allowing
inspect.Signature() to authoritatively detect (and skip) said parameters.

Issue #20326: Argument Clinic now generates separate checksums for the
input and output sections of the block, allowing external tools to verify
that the input has not changed (and thus the output is not out-of-date).
