* [3.7] bpo-9263: _PyObject_Dump() detects freed memory (GH-10061) (GH-10662)Victor Stinner2018-11-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | * bpo-9263: _PyObject_Dump() detects freed memory (GH-10061) _PyObject_Dump() now uses an heuristic to check if the object memory has been freed: log "<freed object>" in that case. The heuristic rely on the debug hooks on Python memory allocators which fills the memory with DEADBYTE (0xDB) when memory is deallocated. Use PYTHONMALLOC=debug to always enable these debug hooks. (cherry picked from commit 82af0b63b07aa8d92b50098e382b458143cfc677) * bpo-9263: Fix _PyObject_Dump() for freed object (#10661) If _PyObject_Dump() detects that the object is freed, don't try to dump it (exit immediately). Enhance also _PyObject_IsFreed(): it now detects if the pointer itself looks like freed memory. (cherry picked from commit 2cf5d32fd9e61488e8b0be55a2e92a752ba8b06b)
* bpo-32571: Avoid raising unneeded AttributeError and silencing it in C code ↵Serhiy Storchaka2018-01-251-2/+11
| | | | | (GH-5222) Add two new private APIs: _PyObject_LookupAttr() and _PyObject_LookupAttrId()
* bpo-32544: Speed up hasattr() and getattr() (GH-5173)INADA Naoki2018-01-161-1/+3
| | | | | AttributeError was raised always when attribute is not found. This commit skip raising AttributeError when `tp_getattro` is `PyObject_GenericGetAttr`. It makes hasattr() and getattr() about 4x faster when attribute is not found.
* bpo-32030: Add more options to _PyCoreConfig (#4485)Victor Stinner2017-11-211-1/+0
| | | | | | Py_Main() now handles two more -X options: * -X showrefcount: new _PyCoreConfig.show_ref_count field * -X showalloccount: new _PyCoreConfig.show_alloc_count field

| | | | This function returns the last component of tp_name after a dot. Returns tp_name itself if it doesn't contain a dot.
* bpo-30860: Fix a refleak. (#3567)Eric Snow2017-09-141-2/+1
| | | | | Resolves bpo-31420. (This was accidentally reverted when in #3565.)
* bpo-31404: Revert "remove modules from Py_InterpreterState (#1638)" (#3565)Eric Snow2017-09-141-1/+2
| | | PR #1638, for bpo-28411, causes problems in some (very) edge cases. Until that gets sorted out, we're reverting the merge. PR #3506, a fix on top of #1638, is also getting reverted.

* bpo-30860: Consolidate stateful runtime globals. (#3397)Eric Snow2017-09-081-2/+0
| | | | | | | * 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).

Disable test_gdb: python-gdb.py is not updated yet to the new structure of compact dictionaries (issue #28023). Patch written by INADA Naoki.
