* | _tracemalloc: use compact key for tracesVictor Stinner2016-03-231-1/+61
| | | | | | | | | | | | Issue #26588: Optimize memory footprint of _tracemalloc before non-zero domain is used. Start with compact key (Py_uintptr_t) and also switch to pointer_t key when the first memory block with a non-zero domain is tracked.
* | Cleanup hashtable.hVictor Stinner2016-03-231-26/+24
| | | | | | | | | | | | | | | | | | | | | | | | 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 Stinner2016-03-231-11/+27
| | | | | | | | | | | | | | * Optimize tracemalloc_add_trace(): modify hashtable entry data (trace) if the memory block is already tracked, rather than trying to remove the old trace and then add a new trace. * Add _Py_HASHTABLE_ENTRY_WRITE_DATA() macro
* | Issue #26588:Victor Stinner2016-03-231-1/+1
| | | | | | | | | | | | | | | | * _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
* | Issue #26588: Optimize tracemalloc_realloc()Victor Stinner2016-03-231-1/+6
| | | | | | | | No need to remove the old trace if the memory block didn't move.

| * Fix _tracemalloc start/stopVictor Stinner2016-03-221-14/+0
| | | | | | | | | | | | | | | | | | Issue #26588: Fix _tracemalloc start/stop: don't play with the reentrant flag. set_reentrant(1) fails with an assertion error if tracemalloc_init() is called first in a thread A and tracemalloc_start() is called second in a thread B. The tracemalloc is imported in a thread A. Importing the module calls tracemalloc_init(). tracemalloc.start() is called in a thread B.

* | Add C functions _PyTraceMalloc_Track()Victor Stinner2016-03-221-11/+71
| | | | | | | | | | | | | | | | Issue #26530: * Add C functions _PyTraceMalloc_Track() and _PyTraceMalloc_Untrack() to track memory blocks using the tracemalloc module. * Add _PyTraceMalloc_GetTraceback() to get the traceback of an object.
* | tracemalloc now supports domainsVictor Stinner2016-03-221-53/+214
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue #26588: * The _tracemalloc now supports tracing memory allocations of multiple address spaces (domains). * Add domain parameter to tracemalloc_add_trace() and tracemalloc_remove_trace(). * tracemalloc_add_trace() now starts by removing the previous trace, if any. * _tracemalloc._get_traces() now returns a list of (domain, size, traceback_frames): the domain is new. * Add tracemalloc.DomainFilter * tracemalloc.Filter: add an optional domain parameter to the constructor and a domain attribute * Sublte change: use Py_uintptr_t rather than void* in the traces key. * Add tracemalloc_config.use_domain, currently hardcoded to 1
* | Simplify implementation of hashtable.cVictor Stinner2016-03-221-6/+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 Stinner2016-03-211-37/+68
| | | | | | | | | | | | 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*).

|/ | | | | | PyObject_Calloc(), _PyObject_GC_Calloc(). bytes(int) and bytearray(int) are now using ``calloc()`` instead of ``malloc()`` for large objects which is faster and use less memory (until the bytearray buffer is filled with data).
