* | Cleanup hashtable.hVictor Stinner2016-03-231-22/+33
| | | | | | | | | | | | | | | | | | | | | | | | 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 Stinner2016-03-231-6/+4
| | | | | | | | | | | | | | | | * _Py_HASHTABLE_ENTRY_DATA: change type from "char *" to "const void *" * Add _Py_HASHTABLE_ENTRY_WRITE_PKEY() macro * Rename _Py_HASHTABLE_ENTRY_WRITE_DATA() macro to _Py_HASHTABLE_ENTRY_WRITE_PDATA() * Add _Py_HASHTABLE_ENTRY_WRITE_DATA() macro
* | Remove _Py_hashtable_delete()Victor Stinner2016-03-221-0/+3
| | | | | | | | | | | | Issue #26588: Remove _Py_hashtable_delete() from hashtable.h since the function is not used. Keep the C code in hashtable.c as commented code if someone needs it later.
* | Simplify implementation of hashtable.cVictor Stinner2016-03-221-47/+8
| | | | | | | | | | | | | | | | | | | | | | Issue #26588: Remove copy_data, free_data and get_data_size callbacks from hashtable.h. These callbacks are not used in Python and makes the code more complex. Remove also the _Py_HASHTABLE_ENTRY_DATA_AS_VOID_P() macro which uses an unsafe pointer dereference (can cause memory alignment issue). Replace the macro usage with _Py_HASHTABLE_ENTRY_READ_DATA() which is implemented with the safe memcpy() function.
* | hashtable.h now supports keys of any sizeVictor Stinner2016-03-211-58/+89
| | | | | | | | | | | | 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*).

* | _tracemalloc: add domain to trace keysVictor Stinner2016-03-181-43/+62

* | On memory error, dump the memory block tracebackVictor Stinner2016-03-151-3/+3
|/ | | | | | Issue #26564: _PyObject_DebugDumpAddress() now dumps the traceback where a memory block was allocated on memory block. Use the tracemalloc module to get the traceback.
