* bpo-30696: Fix the REPL looping endlessly when no memory (GH-4160)xdegaye2017-11-121-18/+42
|
* bpo-28180: Fix the implementation of PEP 538 on Android (GH-4334)xdegaye2017-11-121-12/+65

* bpo-31572: Get rid of _PyObject_HasAttrId() in the ASDL parser. (#3725)Serhiy Storchaka2017-11-111-610/+774
| | | Silence only expected AttributeError.
* bpo-31572: Don't silence unexpected errors in the _warnings module. (#3731)Serhiy Storchaka2017-11-111-68/+89
| | | | | Get rid of _PyObject_HasAttrId() and PyDict_GetItemString(). Silence only expected AttributeError, KeyError and ImportError when get an attribute, look up in a dict or import a module.
* Add the const qualifier to "char *" variables that refer to literal strings. ↵Serhiy Storchaka2017-11-115-5/+6
| | | | (#4370)
* Replace KB unit with KiB (#4293)Victor Stinner2017-11-083-7/+7
| | | | | | | | | | | 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-31415: Improve error handling and caching of the importtime option. (#4138)Serhiy Storchaka2017-11-071-13/+20

* Fix miscellaneous typos (#4275)luzpaz2017-11-053-3/+3

* bpo-28994: PyErr_NormalizeException() no longer use C stack for recursion. ↵Serhiy Storchaka2017-11-051-39/+33
| | | | | (#2035) MemoryError raised when normalizing a RecursionError raised during exception normalization now not always causes a fatal error.
* bpo-31415: Support PYTHONPROFILEIMPORTTIME envvar equivalent to -X ↵Barry Warsaw2017-11-021-4/+11
| | | | | | importtime (#4240) Support PYTHONPROFILEIMPORTTIME envvar equivalent to -X importtime
* bpo-31784: Implement PEP 564: add time.time_ns() (#3989)Victor Stinner2017-11-021-19/+86
| | | | | | | | | | | | | | | | | | | | | | | | | Add new time functions: * time.clock_gettime_ns() * time.clock_settime_ns() * time.monotonic_ns() * time.perf_counter_ns() * time.process_time_ns() * time.time_ns() Add new _PyTime functions: * _PyTime_FromTimespec() * _PyTime_FromNanosecondsObject() * _PyTime_FromTimeval() Other changes: * Add also os.times() tests to test_os. * pytime_fromtimeval() and pytime_fromtimeval() now return _PyTime_MAX or _PyTime_MIN on overflow, rather than undefined behaviour * _PyTime_FromNanoseconds() parameter type changes from long long to _PyTime_t
* bpo-28936: Detect lexically first syntax error first (#4097)Ivan Levkivskyi2017-10-261-18/+16
| | | | Lexically first global and nonlocal syntax errors at given scope should be detected first.
* Fix trailing whitespaces in C files. (#4130)Serhiy Storchaka2017-10-261-1/+1
|
* bpo-30697: Fix PyErr_NormalizeException() when no memory (GH-2327)xdegaye2017-10-261-16/+30
|
* bpo-21720: Restore the Python 2.7 logic in handling a fromlist. (#4118)Serhiy Storchaka2017-10-261-1773/+1783
| | | | | | BytesWarning no longer emitted when the fromlist argument of __import__() or the __all__ attribute of the module contain bytes instances.
* bpo-31857: Make the behavior of USE_STACKCHECK deterministic (#4098)pdox2017-10-262-1/+4
|
* remove support for splitting the ceval switch into multiple switches (#4099)Benjamin Peterson2017-10-251-10/+0
| | | | | | | This kludge is from 1992. Any C99 compiler is going to be able to handle the ceval dispatch switch. Anyway, we have much bigger switches than the ceval dispatch one around. (See, e.g., Objects/unicodetype_db.h.)
* bpo-31845: Fix reading flags from environment (GH-4105)Nick Coghlan2017-10-251-14/+23
| | | | | | | | | | The startup refactoring means command line settings are now applied after settings are read from the environment. This updates the way command line settings are applied to account for that, ensures more settings are first read from the environment in _PyInitializeCore, and adds a simple test case covering the flags that are easy to check.
* bpo-30768: Recompute timeout on interrupted lock (GH-4103)Victor Stinner2017-10-242-10/+54
| | | | | | | | | | | | | | | | 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-30817: Fix PyErr_PrintEx() when no memory (#2526)xdegaye2017-10-231-3/+9
|
* Move exc state to generator. Fixes bpo-25612 (#1773)Mark Shannon2017-10-224-127/+64
| | | Move exception state information from frame objects to coroutine (generator/thread) object where it belongs.
* bpo-31825: Fixed OverflowError in the 'unicode-escape' codec (#4058)Serhiy Storchaka2017-10-201-1/+1
| | | | and in codecs.escape_decode() when decode an escaped non-ascii byte.
* Move opcode tracing to occur after the possible update to f_lineno. (GH-3798)George King2017-10-191-4/+4

* bpo-28603: Fix formatting tracebacks for unhashable exceptions (#4014)Zane Bitter2017-10-171-3/+18

* bpo-31773: _PyTime_GetPerfCounter() uses _PyTime_t (GH-3983)Victor Stinner2017-10-162-42/+128
| | | | | | | | * Rewrite win_perf_counter() to only use integers internally. * Add _PyTime_MulDiv() which compute "ticks * mul / div" in two parts (int part and remaining) to prevent integer overflow. * Clock frequency is checked at initialization for integer overflow. * Enhance also pymonotonic() to reduce the precision loss on macOS (mach_absolute_time() clock).
* bpo-31780: Fix incorrect error message for ',x', ',b', ',o' specs (#4002)Dargor2017-10-151-2/+2
| | | Patch by Pablo.
* bpo-31773: time.perf_counter() uses again double (GH-3964)Victor Stinner2017-10-122-21/+27
| | | | | | | | time.clock() and time.perf_counter() now use again C double internally. Remove also _PyTime_GetWinPerfCounterWithInfo(): use _PyTime_GetPerfCounterDoubleWithInfo() instead on Windows.
* Cleanup pytime.c (#3955)Victor Stinner2017-10-111-54/+76
| | | | | * Move _PyTime_overflow() at the top * Move assertion on numerator into _PyTime_ObjectToDenominator() * PEP 7: add { ... } to if blocks
* bpo-31415: Add _PyTime_GetPerfCounter() and use it for -X importtime (#3936)Victor Stinner2017-10-102-12/+73
| | | | | * Add _PyTime_GetPerfCounter() * Use _PyTime_GetPerfCounter() for -X importtime

* bpo-25658: Implement PEP 539 for Thread Specific Storage (TSS) API (GH-1362)Masayuki Yamamoto2017-10-065-77/+228
| | | | | | | | | See PEP 539 for details. Highlights of changes: - Add Thread Specific Storage (TSS) API - Document the Thread Local Storage (TLS) API as deprecated - Update code that used TLS API to use TSS API
* bpo-31708: Allow async generator expressions in synchronous functions (#3905)Yury Selivanov2017-10-061-1/+1

* bpo-30406: Make async and await proper keywords (#1669)Jelle Zijlstra2017-10-062-190/+198
| | | Per PEP 492, 'async' and 'await' should become proper keywords in 3.7.
* PEP 553 built-in breakpoint() function (bpo-31353) (#3355)Barry Warsaw2017-10-052-0/+103
| | | Implement PEP 553, built-in breakpoint() with support from sys.breakpointhook(), along with documentation and tests. Closes bpo-31353
* remove tabs from getcompiler.c (#3892)Benjamin Peterson2017-10-051-1/+1

* bpo-30404: The -u option now makes the stdout and stderr streams totally ↵Serhiy Storchaka2017-10-041-4/+8
| | | | unbuffered. (#1667)
* bpo-31683: Py_FatalError() now supports long error messages (#3878)Victor Stinner2017-10-041-20/+42
| | | | | On Windows, Py_FatalError() now limits the size to 256 bytes of the buffer used to call OutputDebugStringW(). Previously, the size depended on the length of the error message.
* bpo-31415: Add `-X importtime` option (GH-3490)INADA Naoki2017-10-031-0/+42
| | | | | | It shows show import time of each module. It's useful for optimizing startup time. Typical usage: python -X importtime -c 'import requests'

* bpo-31588: Validate return value of __prepare__() methods (GH-3764)Oren Milman2017-09-271-0/+7
| | | | | | | | | | Class execution requires that __prepare__() methods return a proper execution namespace. Check for that immediately after calling __prepare__(), rather than passing it through to the code execution machinery and potentially triggering SystemError (in debug builds) or a cryptic TypeError (in release builds). Patch by Oren Milman.
