[3.7] Fix misleading mentions of tp_size in comments. (GH-9136)

2018-09-10T17:22:55+00:00

Many type object initializations labeled a field "tp_size" in the
comment, but the name of that field is tp_basicsize..

bpo-32544: Speed up hasattr() and getattr() (GH-5173)

2018-01-16T11:52:41+00:00

AttributeError was raised always when attribute is not found.
This commit skip raising AttributeError when `tp_getattro` is `PyObject_GenericGetAttr`.
It makes hasattr() and getattr() about 4x faster when attribute is not found.

Fix CID-1420310: cast PY_TIMEOUT_MAX to _Py_time_t (#4646)

2017-11-30T22:03:47+00:00

Fix the following false-alarm Coverity warning:

    Result is not floating-point
    (UNINTENDED_INTEGER_DIVISION)integer_division: Dividing integer
    expressions 9223372036854775807LL and 1000LL, and then converting
    the integer quotient to type double. Any remainder, or fractional
    part of the quotient, is ignored.

    To compute and use a non-integer quotient, change or cast either
    operand to type double. If integer division is intended, consider
    indicating that by casting the result to type long long .

Replace KB unit with KiB (#4293)

2017-11-08T22:44:44+00:00

kB (*kilo* byte) unit means 1000 bytes, whereas KiB ("kibibyte")
means 1024 bytes. KB was misused: replace kB or KB with KiB when
appropriate.

Same change for MB and GB which become MiB and GiB.

Change the output of Tools/iobench/iobench.py.

Round also the size of the documentation from 5.5 MB to 5 MiB.

bpo-30768: Recompute timeout on interrupted lock (GH-4103)

2017-10-24T23:53:32+00:00

Fix the pthread+semaphore implementation of
PyThread_acquire_lock_timed() when called with timeout > 0 and
intr_flag=0: recompute the timeout if sem_timedwait() is interrupted
by a signal (EINTR).

See also the PEP 475.

The pthread implementation of PyThread_acquire_lock() now fails with
a fatal error if the timeout is larger than PY_TIMEOUT_MAX, as done
in the Windows implementation.

The check prevents any risk of overflow in PyThread_acquire_lock().

Add also PY_DWORD_MAX constant.

bpo-31806: Use _PyTime_ROUND_TIMEOUT for the timeout argument parsing in more functions (#4026)

2017-10-18T07:13:09+00:00

Fix timeout rounding in time.sleep(), threading.Lock.acquire() and
socket.socket.settimeout() to round correctly negative timeouts between -1.0 and
0.0. The functions now block waiting for events as expected. Previously, the
call was incorrectly non-blocking.

bpo-30860: Consolidate stateful runtime globals. (#3397)

2017-09-08T05:51:28+00:00

* group the (stateful) runtime globals into various topical structs
* consolidate the topical structs under a single top-level _PyRuntimeState struct
* add a check-c-globals.py script that helps identify runtime globals

Other globals are excluded (see globals.txt and check-c-globals.py).

bpo-31370: Remove support for threads-less builds (#3385)

2017-09-07T16:56:24+00:00

* Remove Setup.config
* Always define WITH_THREAD for compatibility.

Revert "bpo-30860: Consolidate stateful runtime globals." (#3379)

2017-09-06T04:43:08+00:00

Windows buildbots started failing due to include-related errors.
