[3.7] bpo-9263: _PyObject_Dump() detects freed memory (GH-10061) (GH-10662)

2018-11-22T16:15:37+00:00

* 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 "" 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 (GH-5222)

2018-01-25T08:49:40+00:00

Add two new private APIs: _PyObject_LookupAttr() and _PyObject_LookupAttrId()

bpo-32544: Speed up hasattr() and getattr() (GH-5173)

2018-01-16T11:52:41+00:00

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.

Py_Main() now handles two more -X options:

* -X showrefcount: new _PyCoreConfig.show_ref_count field
* -X showalloccount: new _PyCoreConfig.show_alloc_count field

Returns tp_name itself if it doesn't contain a dot.

bpo-30860: Fix a refleak. (#3567)

Resolves bpo-31420.

(This was accidentally reverted when in #3565.)

bpo-31404: Revert "remove modules from Py_InterpreterState (#1638)" (#3565)

2017-09-14T06:46:04+00:00

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.

* Drop warnoptions from PyInterpreterState.

* Drop xoptions from PyInterpreterState.

* Don't set warnoptions and _xoptions again.

* Decref after adding to sys.__dict__.

* Drop an unused macro.

* Check sys.xoptions *before* we delete it.
