* bpo-31572: Get rid of _PyObject_HasAttrId() in dict and OrderedDict. (#3728)Serhiy Storchaka2017-11-112-21/+47
| | | | | Silence only AttributeError when get "key" and "items" attributes in the constructor and the update() method of dict and OrderedDict .
* Add the const qualifier to "char *" variables that refer to literal strings. ↵Serhiy Storchaka2017-11-117-21/+24
| | | | (#4370)
* Replace KB unit with KiB (#4293)Victor Stinner2017-11-082-2/+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-31626: Mark ends of the reallocated block in debug build. (#4210)Serhiy Storchaka2017-11-071-19/+57
| | | | | | Few bytes at the begin and at the end of the reallocated blocks, as well as the header and the trailer, now are erased before calling realloc() in debug build. This will help to detect using or double freeing the reallocated block.

* bpo-18835: Cleanup pymalloc (#4200)Victor Stinner2017-10-311-472/+533
| | | | | | | | | | | | | | | | | | | | | | | | | | | Cleanup pymalloc: * Rename _PyObject_Alloc() to pymalloc_alloc() * Rename _PyObject_FreeImpl() to pymalloc_free() * Rename _PyObject_Realloc() to pymalloc_realloc() * pymalloc_alloc() and pymalloc_realloc() don't fallback on the raw allocator anymore, it now must be done by the caller * Add "success" and "failed" labels to pymalloc_alloc() and pymalloc_free() * pymalloc_alloc() and pymalloc_free() don't update num_allocated_blocks anymore: it should be done in the caller * _PyObject_Calloc() is now responsible to fill the memory block allocated by pymalloc with zeros * Simplify pymalloc_alloc() prototype * _PyObject_Realloc() now calls _PyObject_Malloc() rather than calling directly pymalloc_alloc() _PyMem_DebugRawAlloc() and _PyMem_DebugRawRealloc(): * document the layout of a memory block * don't increase the serial number if the allocation failed * check for integer overflow before computing the total size * add a 'data' variable to make the code easiler to follow test_setallocators() of _testcapimodule.c now test also the context.
* bpo-31626: Fixed a bug in debug memory allocator. (#3844)Serhiy Storchaka2017-10-311-11/+2
| | | | Removed a code that incorrectly detected in-place resizing in realloc() and wrote to freed memory.
* bpo-20047: Make bytearray methods partition() and rpartition() rejecting (#4158)Serhiy Storchaka2017-10-296-28/+51
| | | separators that are not bytes-like objects.
* bpo-30697: Fix PyErr_NormalizeException() when no memory (GH-2327)xdegaye2017-10-261-32/+0

* bpo-31835: Optimize also FASTCALL using __future__ (#4087)Victor Stinner2017-10-251-2/+2
| | | | | _PyFunction_FastCallDict() and _PyFunction_FastCallKeywords() now also takes the fast path if the code object uses __future__ (CO_FUTURE_xxx flags).
* Move exc state to generator. Fixes bpo-25612 (#1773)Mark Shannon2017-10-222-23/+36
| | | 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 Storchaka2017-10-202-2/+2
| | | | and in codecs.escape_decode() when decode an escaped non-ascii byte.
* bpo-28280: Make PyMapping_Keys(), PyMapping_Values() and PyMapping_Items() ↵Oren Milman2017-10-081-27/+49

* bpo-31336: Speed up type creation. (#3279)scoder2017-10-011-52/+108
| | | | | Speed up class creation by 10-20% by reducing the overhead in the necessary special method lookups.

| | | | | (#3631) Affected classes are bytearray, array, deque, defaultdict, count and repeat.
* bpo-30486: Make cell_set_contents() symbol private (#3668)Victor Stinner2017-09-201-1/+1

| | | | attribute. (#3620)
* bpo-31497: Add private helper _PyType_Name(). (#3630)Serhiy Storchaka2017-09-173-25/+19
| | | | This function returns the last component of tp_name after a dot. Returns tp_name itself if it doesn't contain a dot.
* bpo-28411: Support other mappings in PyInterpreterState.modules. (#3593)Eric Snow2017-09-151-3/+1
| | | | | 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 Warsaw2017-09-146-70/+46
| | | | | | | * 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-30860: Fix deadcode in obmalloc.c (#3499)Victor Stinner2017-09-141-2/+2
| | | | | | Fix Coverity CID 1417587: _PyMem_Initialize() contains code which is never executed. Replace the runtime check with a build assertion.
* bpo-28411: Isolate PyInterpreterState.modules (#3575)Eric Snow2017-09-142-5/+11
| | | | | 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 Snow2017-09-141-12/+15
| | | | | Resolves bpo-31420. (This was accidentally reverted when in #3565.)
* bpo-31404: Revert "remove modules from Py_InterpreterState (#1638)" (#3565)Eric Snow2017-09-133-25/+17
| | | 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-31462: Remove trailing whitespaces. (#3564)Serhiy Storchaka2017-09-142-2/+2
|
* bpo-30860: Fix a refleak. (#3506)Eric Snow2017-09-111-12/+15
| | | | | | | | | | | | | | * 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-31373: remove overly strict float range checks (#3486)Benjamin Peterson2017-09-101-2/+2
| | | | | 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.

* optimize all_name_chars (#3442)Benjamin Peterson2017-09-071-14/+14
| | | Remove redundant PyUnicode_Check call. Use a static table for checking chars.
* bpo-31344: Per-frame control of trace events (GH-3417)Nick Coghlan2017-09-081-0/+4
| | | | | | | | | 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.
