* bpo-40602: Write unit tests for _Py_hashtable_t (GH-20091)Victor Stinner2020-05-141-1/+1
| | | | | | | Cleanup also hashtable.c. Rename _Py_hashtable_t members: * Rename entries to nentries * Rename num_buckets to nbuckets
* bpo-40609: _Py_hashtable_t values become void* (GH-20065)Victor Stinner2020-05-131-5/+4
| | | | | | | | | | | | | | | | | | | | | _Py_hashtable_t values become regular "void *" pointers. * Add _Py_hashtable_entry_t.data member * Remove _Py_hashtable_t.data_size member * Remove _Py_hashtable_t.get_func member. It is no longer needed to specialize _Py_hashtable_get() for a specific value size, since all entries now have the same size (void*). * Remove the following macros: * _Py_HASHTABLE_GET() * _Py_HASHTABLE_SET() * _Py_HASHTABLE_SET_NODATA() * _Py_HASHTABLE_POP() * Rename _Py_hashtable_pop() to _Py_hashtable_steal() * _Py_hashtable_foreach() callback now gets key and value rather than entry. * Remove _Py_hashtable_value_destroy_func type. value_destroy_func callback now only has a single parameter: data (void*).
* bpo-40609: Add destroy functions to _Py_hashtable (GH-20062)Victor Stinner2020-05-131-13/+11
| | | | | | Add key_destroy_func and value_destroy_func parameters to _Py_hashtable_new_full(). marshal.c and _tracemalloc.c use these destroy functions.
* bpo-40609: Remove _Py_hashtable_t.key_size (GH-20060)Victor Stinner2020-05-131-4/+2
| | | | | | | | | | Rewrite _Py_hashtable_t type to always store the key as a "const void *" pointer. Add an explicit "key" member to _Py_hashtable_entry_t. Remove _Py_hashtable_t.key_size member. hash and compare functions drop their hash table parameter, and their 'key' parameter type becomes "const void *".
* bpo-40602: Rename hashtable.h to pycore_hashtable.h (GH-20044)Victor Stinner2020-05-121-1/+1
| | | | | | | * Move Modules/hashtable.h to Include/internal/pycore_hashtable.h * Move Modules/hashtable.c to Python/hashtable.c * Python is now linked to hashtable.c. _tracemalloc is no longer linked to hashtable.c. Previously, marshal.c got hashtable.c via _tracemalloc.c which is built as a builtin module.
* bpo-39943: Clean up marshal.c. (GH-19236)Serhiy Storchaka2020-03-311-57/+31
| | | | | | * Add consts. * Remove redundant casts and checks. * Use concrete C API macros. * Avoid raising and silencing OverflowError for ints.
* closes bpo-39605: Fix some casts to not cast away const. (GH-18453)Andy Lester2020-02-111-1/+1
| | | | | | | | | | | | | | | gcc -Wcast-qual turns up a number of instances of casting away constness of pointers. Some of these can be safely modified, by either: Adding the const to the type cast, as in: - return _PyUnicode_FromUCS1((unsigned char*)s, size); + return _PyUnicode_FromUCS1((const unsigned char*)s, size); or, Removing the cast entirely, because it's not necessary (but probably was at one time), as in: - PyDTrace_FUNCTION_ENTRY((char *)filename, (char *)funcname, lineno); + PyDTrace_FUNCTION_ENTRY(filename, funcname, lineno); These changes will not change code, but they will make it much easier to check for errors in consts
* bpo-39573: Use Py_SET_SIZE() function (GH-18402)Victor Stinner2020-02-071-1/+1
| | | | Replace direct acccess to PyVarObject.ob_size with usage of the Py_SET_SIZE() function.
* bpo-39573: Use Py_TYPE() macro in Python and Include directories (GH-18391)Victor Stinner2020-02-071-1/+1
| | | Replace direct access to PyObject.ob_type with Py_TYPE().

* bpo-36540: PEP 570 -- Implementation (GH-12701)Pablo Galindo2019-04-291-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit contains the implementation of PEP570: Python positional-only parameters. * Update Grammar/Grammar with new typedarglist and varargslist * Regenerate grammar files * Update and regenerate AST related files * Update code object * Update marshal.c * Update compiler and symtable * Regenerate importlib files * Update callable objects * Implement positional-only args logic in ceval.c * Regenerate frozen data * Update standard library to account for positional-only args * Add test file for positional-only args * Update other test files to account for positional-only args * Add News entry * Update inspect module and related tests
* bpo-35436: Add missing PyErr_NoMemory() calls and other minor bug fixes. ↵Zackery Spytz2018-12-071-2/+3

* Use _PyObject_CallMethodIdObjArgs()Victor Stinner2016-12-091-1/+1
| | | | | | | | | Issue #28915: Replace _PyObject_CallMethodId() with _PyObject_CallMethodIdObjArgs() in various modules when the format string was only made of "O" formats, PyObject* arguments. _PyObject_CallMethodIdObjArgs() avoids the creation of a temporary tuple and doesn't have to parse a format string.
* Replace PyObject_CallFunction() with fastcallVictor Stinner2016-12-011-1/+1
| | | | | | | | | | | | | | | | | Replace PyObject_CallFunction(func, "O", arg) and PyObject_CallFunction(func, "O", arg, NULL) with _PyObject_CallArg1(func, arg) Replace PyObject_CallFunction(func, NULL) with _PyObject_CallNoArg(func) _PyObject_CallNoArg() and _PyObject_CallArg1() are simpler and don't allocate memory on the C stack.

| | | | | | | | | | | | Issue #26588: * Pass the hash table rather than the key size to hash and compare functions * _Py_HASHTABLE_READ_KEY() and _Py_HASHTABLE_ENTRY_READ_KEY() macros now expect the hash table as the first parameter, rather than the key size * tracemalloc_get_traces_fill(): use _Py_HASHTABLE_ENTRY_READ_DATA() rather than pointer dereference * Remove the _Py_HASHTABLE_ENTRY_WRITE_PKEY() macro * Move "PKEY" and "PDATA" macros inside hashtable.c
* Issue #26588:Victor Stinner2016-03-231-1/+1

* hashtable.h now supports keys of any sizeVictor Stinner2016-03-211-5/+10
| | | | | | Issue #26588: hashtable.h now supports keys of any size, not only sizeof(void*). It allows to support key larger than sizeof(void*), but also to use less memory for key smaller than sizeof(void*).
