* bpo-33012: Fix invalid function cast warnings with gcc 8 for METH_NOARGS. ↵Siddhesh Poyarekar2018-04-291-19/+19
| | | | | | | | | (GH-6030) METH_NOARGS functions need only a single argument but they are cast into a PyCFunction, which takes two arguments. This triggers an invalid function cast warning in gcc8 due to the argument mismatch. Fix this by adding a dummy unused argument.
* bpo-32747: Remove trailing spaces in docstrings. (GH-5491)oldk2018-02-021-1/+1

* bpo-32544: Speed up hasattr() and getattr() (GH-5173)INADA Naoki2018-01-161-2/+4
| | | | | 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)Victor Stinner2017-11-301-1/+1
| | | | | | | | | | | | | 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)Victor Stinner2017-11-081-2/+2
| | | | | | | | | | | 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)Victor Stinner2017-10-241-2/+4
| | | | | | | | | | | | | | | | 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 ↵Pablo Galindo2017-10-181-2/+2
| | | | | | | | | more functions (#4026) 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)Eric Snow2017-09-081-5/+7
| | | | | | | * 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-30860: Consolidate stateful runtime globals. (#2594)Eric Snow2017-09-061-5/+6

* bpo-6532: Make the thread id an unsigned integer. (#781)Serhiy Storchaka2017-03-231-15/+14
| | | | | | | | | | | * bpo-6532: Make the thread id an unsigned integer. From C API side the type of results of PyThread_start_new_thread() and PyThread_get_thread_ident(), the id parameter of PyThreadState_SetAsyncExc(), and the thread_id field of PyThreadState changed from "long" to "unsigned long". * Restore a check in thread_get_ident().

* | Issue #22117: Add a new _PyTime_FromSeconds() functionVictor Stinner2015-04-031-1/+1
| | | | | | | | | | Fix also _Py_InitializeEx_Private(): initialize time before initializing import, import_init() uses the _PyTime API (for thread locks).

* | Issue #22117: Replace usage of _PyTime_ROUND_UP with _PyTime_ROUND_CEILINGVictor Stinner2015-03-301-3/+4
| | | | | | | | | | All these functions only accept positive timeouts, so this change has no effect in practice.
* | Issue #22117: The thread module uses the new _PyTime_t timestamp APIVictor Stinner2015-03-281-75/+64
| | | | | | | | | | | | | | | | | | Add also a new _PyTime_AsMicroseconds() function. threading.TIMEOUT_MAX is now be smaller: only 292 years instead of 292,271 years on 64-bit system for example. Sorry, your threads will hang a *little bit* shorter. Call me if you want to ensure that your locks wait longer, I can share some tricks with you.

| | | | | | | | | | threading.Lock.acquire(), threading.RLock.acquire() and socket operations now use a monotonic clock, instead of the system clock, when a timeout is used.
