* bpo-35081: Add pycore_ prefix to internal header files (GH-10263)Victor Stinner2018-10-311-1/+1
| | | | | | | | | | | | | | | | | | | | * 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".
* bpo-34573: Simplify __reduce__() of set and dict iterators. (GH-9050)Sergey Fedoseev2018-10-201-25/+3
| | | | Simplify the pickling of set and dictionary objects iterators by consuming the iterator into a list with PySequence_List.
* bpo-1621: Avoid signed integer overflow in set_table_resize(). (GH-9059)Sergey Fedoseev2018-09-111-8/+3
| | | | | | | | 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 -->

* bpo-33012: Fix invalid function cast warnings with gcc 8 for METH_NOARGS. ↵Siddhesh Poyarekar2018-04-291-20/+20
| | | | | | | | | (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.

| | | | | | | * 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-30592: Fixed error messages for some builtins. (#1996)Serhiy Storchaka2017-06-081-2/+2
| | | | | 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.

* bpo-29949: Fix set memory usage regression (GH-943)INADA Naoki2017-04-011-6/+5
| | | | | Revert "Minor factoring: move redundant resize scaling logic into the resize function." This reverts commit 4897300276d870f99459c82b937f0ac22450f0b6.

* Reduce load factor (from 66% to 60%) to improve effectiveness of linear probing.Raymond Hettinger2017-02-041-3/+3
| | | | | | | 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).
