Serhiy Storchaka	41c57b3353	bpo-37994: Fix silencing all errors if an attribute lookup fails. (GH-15630) Only AttributeError should be silenced.	7 years ago
Raymond Hettinger	88ea166dad	bpo-8425: Fast path for set inplace difference when the second set is large (GH-15590)	7 years ago
Victor Stinner	bed4817d52	Make PyXXX_Fini() functions private (GH-15531) For example, rename PyTuple_Fini() to _PyTuple_Fini(). These functions are only declared in the internal C API.	7 years ago
Raymond Hettinger	1f11cf9521	bpo-37219: Remove erroneous optimization for differencing an empty set (GH-13965)	7 years ago
Jeroen Demeyer	530f506ac9	bpo-36974: tp_print -> tp_vectorcall_offset and tp_reserved -> tp_as_async (GH-13464) Automatically replace tp_print -> tp_vectorcall_offset tp_compare -> tp_as_async tp_reserved -> tp_as_async	7 years ago
Jeroen Demeyer	351c67416b	bpo-35983: skip trashcan for subclasses (GH-11841) Add new trashcan macros to deal with a double deallocation that could occur when the `tp_dealloc` of a subclass calls the `tp_dealloc` of a base class and that base class uses the trashcan mechanism. Patch by Jeroen Demeyer.	7 years ago
Serhiy Storchaka	bb86bf4c4e	bpo-35444: Unify and optimize the helper for getting a builtin object. (GH-11047) This speeds up pickling of some iterators. This fixes also error handling in pickling methods when fail to look up builtin "getattr".	7 years ago
Victor Stinner	bcda8f1d42	bpo-35081: Add Include/internal/pycore_object.h (GH-10640) Move _PyObject_GC_TRACK() and _PyObject_GC_UNTRACK() from Include/objimpl.h to Include/internal/pycore_object.h.	7 years ago
Victor Stinner	621cebe81b	bpo-35081: Rename internal headers (GH-10275) Rename Include/internal/ headers: * pycore_hash.h -> pycore_pyhash.h * pycore_lifecycle.h -> pycore_pylifecycle.h * pycore_mem.h -> pycore_pymem.h * pycore_state.h -> pycore_pystate.h Add missing headers to Makefile.pre.in and PCbuild: * pycore_condvar.h. * pycore_hamt.h * pycore_pyhash.h	7 years ago
Raymond Hettinger	f9ec1b9f52	Neaten the code without any algorithmic change. (GH-10466) Remove unneeded assertion (we already know so is a PySetObject *).	7 years ago
Raymond Hettinger	cf5863faab	Optimize set.pop() to advance a pointer instead of indexing. (GH-10429) Gives approx 20% speed-up using clang depending on the number of elements in the set (the less dense the set, the more the speed-up). Uses the same entry++ logic used elsewhere in the setobject.c code.	7 years ago
Victor Stinner	27e2d1f219	bpo-35081: Add pycore_ prefix to internal header files (GH-10263) * Rename Include/internal/ header files: * pyatomic.h -> pycore_atomic.h * ceval.h -> pycore_ceval.h * condvar.h -> pycore_condvar.h * context.h -> pycore_context.h * pygetopt.h -> pycore_getopt.h * gil.h -> pycore_gil.h * hamt.h -> pycore_hamt.h * hash.h -> pycore_hash.h * mem.h -> pycore_mem.h * pystate.h -> pycore_state.h * warnings.h -> pycore_warnings.h * PCbuild project, Makefile.pre.in, Modules/Setup: add the Include/internal/ directory to the search paths of header files. * Update includes. For example, replace #include "internal/mem.h" with #include "pycore_mem.h".	7 years ago
Sergey Fedoseev	6395844e6a	bpo-34573: Simplify __reduce__() of set and dict iterators. (GH-9050) Simplify the pickling of set and dictionary objects iterators by consuming the iterator into a list with PySequence_List.	7 years ago
Sergey Fedoseev	6c7d67ce83	bpo-1621: Avoid signed integer overflow in set_table_resize(). (GH-9059) Address a C undefined behavior signed integer overflow issue in set object table resizing. Our -fwrapv compiler flag and practical reasons why sets are unlikely to get this large should mean this was never an issue but it was incorrect code that generates code analysis warnings. <!-- issue-number: [bpo-1621](https://www.bugs.python.org/issue1621) --> https://bugs.python.org/issue1621 <!-- /issue-number -->	8 years ago
lekma	491bbedc20	bpo-33391: Fix refleak in set_symmetric_difference (GH-6670)	8 years ago
Siddhesh Poyarekar	55edd0c185	bpo-33012: Fix invalid function cast warnings with gcc 8 for METH_NOARGS. (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.	8 years ago

Serhiy Storchaka	6cca5c8459	bpo-30592: Fixed error messages for some builtins. (#1996 ) Error messages when pass keyword arguments to some builtins that don't support keyword arguments contained double parenthesis: "()()". The regression was introduced by bpo-30534.	9 years ago
Serhiy Storchaka	bf623ae884	bpo-30061: Check if PyObject_Size()/PySequence_Size()/PyMapping_Size() (#1096 ) raised an error. Replace them with using concrete types API that never fails if appropriate.	9 years ago
INADA Naoki	e82cf8675b	bpo-29949: Fix set memory usage regression (GH-943) Revert "Minor factoring: move redundant resize scaling logic into the resize function." This reverts commit `4897300276`.	9 years ago
Serhiy Storchaka	68a001dd59	Issue #29460 : _PyArg_NoKeywords(), _PyArg_NoStackKeywords() and _PyArg_NoPositional() now are macros.	9 years ago
Raymond Hettinger	5cd87a8d61	Reduce load factor (from 66% to 60%) to improve effectiveness of linear probing. Decreased density gives better collision statistics (average of 2.5 probes in a full table versus 3.0 previously) and fewer occurences of starting a second possibly overlapping sequence of 10 linear probes. Makes resizes a little more frequent but each with less work (fewer insertions and fewer collisions).	9 years ago
Raymond Hettinger	e1af6964b4	Remove unnecessary variables. * so->used never gets changed during a resize * so->filled only changes when dummies are present and being eliminated	9 years ago

Serhiy Storchaka	fbb1c5ee06	Issue #26494 : Fixed crash on iterating exhausting iterators. Affected classes are generic sequence iterators, iterators of str, bytes, bytearray, list, tuple, set, frozenset, dict, OrderedDict, corresponding views and os.scandir() iterator.	10 years ago
Raymond Hettinger	3625af5f21	Moved misplaced functions to the section for C API functions.	10 years ago
Raymond Hettinger	2c257ab0f8	Responsibility for argument checking belongs in set.__init__() rather than set.__new__(). See dict.__new__() and list.__new__() for comparison. Neither of those examine or touch args or kwds. That work is done in the __init__() methods.	10 years ago
Raymond Hettinger	b72e21b9ab	Speed-up construction of empty sets by approx 12-14%.	10 years ago
Raymond Hettinger	f50215412c	Add early-out for the common case where kwds is NULL (gives 1.1% speedup).	10 years ago

Serhiy Storchaka	5c4064e8bd	Issue #25421 : __sizeof__ methods of builtin types now use dynamic basic size. This allows sys.getsize() to work correctly with their subclasses with __slots__ defined.	10 years ago
