* pytalloc: Build for Python 3/extrapythonPetr Viktorin2015-03-113-16/+44
| | | | | | | This enables building, installing & testing two versions for pytalloc, for two versions of Python, at the same time. Signed-off-by: Petr Viktorin <pviktori@redhat.com>
* pytalloc: Port to Python 3Petr Viktorin2015-03-114-29/+57
| | | | | | | | | | | | | | | | | | | | | | - Use native string for repr - Use rich comparison Removes the deprecated tp_compare in favor of tp_richcompare. Disparate types cannot be compared (except for == and !=), and True or False objects are returned explicitly. - Use Py_TYPE instead of ob_type This changed to conform to C aliasing rules, see http://legacy.python.org/dev/peps/pep-3123/ - Don't provide CObject creation function A PyCapsule based replacement would be possible, but might not be necessary considering the function is not used much. - Use new-style module initialization Signed-off-by: Petr Viktorin <pviktori@redhat.com>

* pytalloc: Add testsPetr Viktorin2015-03-113-1/+247
| | | | | | | | | Add tests for pytalloc. Since talloc objects can't be created from Python, a C extension with helpers is added. Signed-off-by: Petr Viktorin <pviktori@redhat.com>
* pytalloc: Fix comparison of disparate typesPetr Viktorin2015-03-111-1/+1
| | | | | | | | When fed Python objects of different types, pytalloc_default_cmp compared pointers to PyType objects that weren't part of an array, resulting in undefined behavior. This makes things a bit better (though it still casts ptrdiff_t to int).

* lib: talloc: Allow destructors to reparent the object they're called on.Jeremy Allison2015-03-081-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | If a destructor returns failure (-1) when freeing a child, talloc must then reparent the child. Firstly it tries the owner of any reference, next the parent of the current object calling _talloc_free_children_internal(), and finally the null context in the last resort. If a destructor reparented its own object, which can be a very desirable thing to do (a destructor can make a decision it isn't time to die yet, and as the parent may be going away it might want to move itself to longer-term storage) then this new parent gets overwritten by the existing reparenting logic. This patch checks when freeing a child if it already reparented itself, and if it did doesn't then overwrite the new parent. Makes destructors more flexible.

The interface to talloc_memlimit_update() is very hard to understand and use. The above functions are (to me) much clearer. The goal of these changes is to only update the memlimits on malloc/free/realloc, not on every pool allocation. That way we only count pool creation as allocation from any imposed limits, not allocation from an already created pool.
