* 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'

| | | | | Importlib was instrumented with two dtrace probes to profile import timing. Signed-off-by: Christian Heimes <christian@python.org>

* 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.
* bpo-31566: Fix an assertion failure in _warnings.warn() in case of a bad ↵Oren Milman2017-09-241-3/+4

* Trivial cleanups following bpo-31370 (#3649)Antoine Pitrou2017-09-182-168/+159
| | | | | | * Trivial cleanups following bpo-31370 * Also cleanup the "importlib._bootstrap_external" module
* bpo-28411: Support other mappings in PyInterpreterState.modules. (#3593)Eric Snow2017-09-155-63/+128
| | | | | The concrete PyDict_* API is used to interact with PyInterpreterState.modules in a number of places. This isn't compatible with all dict subclasses, nor with other Mapping implementations. This patch switches the concrete API usage to the corresponding abstract API calls. We also add a PyImport_GetModule() function (and some other helpers) to reduce a bunch of code duplication.
* bpo-31338 (#3374)Barry Warsaw2017-09-158-27/+15
| | | | | | | * Add Py_UNREACHABLE() as an alias to abort(). * Use Py_UNREACHABLE() instead of assert(0) * Convert more unreachable code to use Py_UNREACHABLE() * Document Py_UNREACHABLE() and a few other macros.
* bpo-28411: Isolate PyInterpreterState.modules (#3575)Eric Snow2017-09-145-47/+84
| | | | | A bunch of code currently uses PyInterpreterState.modules directly instead of PyImport_GetModuleDict(). This complicates efforts to make changes relative to sys.modules. This patch switches to using PyImport_GetModuleDict() uniformly. Also, a number of related uses of sys.modules are updated for uniformity for the same reason. Note that this code was already reviewed and merged as part of #1638. I reverted that and am now splitting it up into more focused parts.
* bpo-30860: Fix a refleak. (#3567)Eric Snow2017-09-144-27/+31
| | | | | Resolves bpo-31420. (This was accidentally reverted when in #3565.)
* bpo-31404: Revert "remove modules from Py_InterpreterState (#1638)" (#3565)Eric Snow2017-09-149-238/+111
| | | PR #1638, for bpo-28411, causes problems in some (very) edge cases. Until that gets sorted out, we're reverting the merge. PR #3506, a fix on top of #1638, is also getting reverted.
* bpo-31418: Fix an assertion failure in PyErr_WriteUnraisable() in case of an ↵Oren Milman2017-09-131-1/+1

* bpo-30860: Fix a refleak. (#3506)Eric Snow2017-09-124-27/+31
| | | | | | | | | | | | | | * Drop warnoptions from PyInterpreterState. * Drop xoptions from PyInterpreterState. * Don't set warnoptions and _xoptions again. * Decref after adding to sys.__dict__. * Drop an unused macro. * Check sys.xoptions *before* we delete it.
* bpo-31416: Fix assertion failures in case of a bad warnings.filters or ↵Oren Milman2017-09-111-3/+16
| | | | | warnings.defaultaction. (#3496) Patch by Oren Milman.
* bpo-31373: remove overly strict float range checks (#3486)Benjamin Peterson2017-09-111-4/+0
| | | | | This undoes a853a8ba7850381d49b284295dd6f0dc491dbe44 except for the pytime.c parts. We want to continue to allow IEEE 754 doubles larger than FLT_MAX to be rounded into finite floats. Tests were added to very this behavior.

* bpo-31344: Per-frame control of trace events (GH-3417)Nick Coghlan2017-09-082-9/+17
| | | | | | | | | f_trace_lines: enable/disable line trace events f_trace_opcodes: enable/disable opcode trace events These are intended primarily for testing of the interpreter itself, as they make it much easier to emulate signals arriving at unfortunate times.
