The strategy there +involves using a doubly-linked-list to capture the order. We keep to that +strategy, using a lower-level linked-list. + +About the Linked-List +===================== + +For the linked list we use a basic doubly-linked-list. Using a circularly- +linked-list does have some benefits, but they don't apply so much here +since OrderedDict is focused on the ends of the list (for the most part). +Furthermore, there are some features of generic linked-lists that we simply +don't need for OrderedDict. Thus a simple custom implementation meets our +needs. Alternatives to our simple approach include the QCIRCLE_* +macros from BSD's queue.h, and the linux's list.h. + +Getting O(1) Node Lookup +------------------------ + +One invariant of Python's OrderedDict is that it preserves time complexity +of dict's methods, particularly the O(1) operations. Simply adding a +linked-list on top of dict is not sufficient here; operations for nodes in +the middle of the linked-list implicitly require finding the node first. +With a simple linked-list like we're using, that is an O(n) operation. +Consequently, methods like __delitem__() would change from O(1) to O(n), +which is unacceptable. + +In order to preserve O(1) performance for node removal (finding nodes), we +must do better than just looping through the linked-list. Here are options +we've considered: + +1. use a second dict to map keys to nodes (a la the pure Python version). +2. keep a simple hash table mirroring the order of dict's, mapping each key + to the corresponding node in the linked-list. +3. use a version of shared keys (split dict) that allows non-unicode keys. +4. have the value stored for each key be a (value, node) pair, and adjust + __getitem__(), get(), etc. accordingly. + +The approach with the least performance impact (time and space) is #2, +mirroring the key order of dict's dk_enties with an array of node pointers. +While lookdict() and friends (dk_lookup) don't give us the index into the +array, we make use of pointer arithmetic to get that index. An alternative +would be to refactor lookdict() to provide the index, explicitly exposing +the implementation detail. We could even just use a custom lookup function +for OrderedDict that facilitates our need. However, both approaches are +significantly more complicated than just using pointer arithmetic. + +The catch with mirroring the hash table ordering is that we have to keep +the ordering in sync through any dict resizes. However, that order only +matters during node lookup. We can simply defer any potential resizing +until we need to do a lookup. + +Linked-List Nodes +----------------- + +The current implementation stores a pointer to the associated key only. +One alternative would be to store a pointer to the PyDictKeyEntry instead. +This would save one pointer de-reference per item, which is nice during +calls to values() and items(). However, it adds unnecessary overhead +otherwise, so we stick with just the key. + +Linked-List API +--------------- + +As noted, the linked-list implemented here does not have all the bells and +whistles. However, we recognize that the implementation may need to +change to accommodate performance improvements or extra functionality. To +that end, We use a simple API to interact with the linked-list. Here's a +summary of the methods/macros: + +Node info: + +* _odictnode_KEY(node) +* _odictnode_VALUE(od, node) +* _odictnode_PREV(node) +* _odictnode_NEXT(node) + +Linked-List info: + +* _odict_FIRST(od) +* _odict_LAST(od) +* _odict_EMPTY(od) +* _odict_FOREACH(od, node) - used in place of `for (node=...)` + +For adding nodes: + +* _odict_add_head(od, node) +* _odict_add_tail(od, node) +* _odict_add_new_node(od, key) + +For removing nodes: + +* _odict_pop_node(od, node, key) +* _odict_clear_node(od, node) +* _odict_clear_nodes(od, clear_each) + +Others: + +* _odict_initialize(od) +* _odict_find_node(od, key) +* _odict_keys_equal(od1, od2) + +Used, but specific to the linked-list implementation: + +* _odict_free_fast_nodes(od) + +And here's a look at how the linked-list relates to the OrderedDict API: + +============ === === ==== ==== ==== === ==== ===== ==== ==== === ==== === === +method key val prev next mem 1st last empty iter find add rmv clr keq +============ === === ==== ==== ==== === ==== ===== ==== ==== === ==== === === +__del__ ~ X +__delitem__ free ~ node +__eq__ ~ X +__iter__ X X +__new__ X X +__reduce__ X ~ X +__repr__ X X X +__reversed__ X X +__setitem__ key +__sizeof__ size X +clear ~ ~ X +copy X X X +items X X X +keys X X +move_to_end X X X ~ h/t key +pop free key +popitem X X free X X node +setdefault ~ ? ~ +values X X +============ === === ==== ==== ==== === ==== ===== ==== ==== === ==== === === + +__delitem__ is the only method that directly relies on finding an arbitrary +node in the linked-list. Everything else is iteration or relates to the +ends of the linked-list. + +Situation that Endangers Consistency +------------------------------------ +Using a raw linked-list for OrderedDict exposes a key situation that can +cause problems. If a node is stored in a variable, there is a chance that +the node may have been deallocated before the variable gets used, thus +potentially leading to a segmentation fault. A key place where this shows +up is during iteration through the linked list (via _odict_FOREACH or +otherwise). + +A number of solutions are available to resolve this situation: + +* defer looking up the node until as late as possible and certainly after + any code that could possibly result in a deletion; +* if the node is needed both before and after a point where the node might + be removed, do a check before using the node at the "after" location to + see if the node is still valid; +* like the last one, but simply pull the node again to ensure it's right; +* keep the key in the variable instead of the node and then look up the + node using the key at the point where the node is needed (this is what + we do for the iterators). + +Another related problem, preserving consistent ordering during iteration, +is described below. That one is not exclusive to using linked-lists. + + +Challenges from Subclassing dict +================================ + +OrderedDict subclasses dict, which is an unusual relationship between two +builtin types (other than the base object type). Doing so results in +some complication and deserves further explanation. There are two things +to consider here. First, in what circumstances or with what adjustments +can OrderedDict be used as a drop-in replacement for dict (at the C level)? +Second, how can the OrderedDict implementation leverage the dict +implementation effectively without introducing unnecessary coupling or +inefficiencies? + +This second point is reflected here and in the implementation, so the +further focus is on the first point. It is worth noting that for +overridden methods, the dict implementation is deferred to as much as +possible. Furthermore, coupling is limited to as little as is reasonable. + +Concrete API Compatibility +-------------------------- + +Use of the concrete C-API for dict (PyDict_*) with OrderedDict is +problematic. (See http://bugs.python.org/issue10977.) The concrete API +has a number of hard-coded assumptions tied to the dict implementation. +This is, in part, due to performance reasons, which is understandable +given the part dict plays in Python. + +Any attempt to replace dict with OrderedDict for any role in the +interpreter (e.g. **kwds) faces a challenge. Such any effort must +recognize that the instances in affected locations currently interact with +the concrete API. + +Here are some ways to address this challenge: + +1. Change the relevant usage of the concrete API in CPython and add + PyDict_CheckExact() calls to each of the concrete API funcions. +2. Adjust the relevant concrete API functions to explicitly accommodate + OrderedDict. +3. As with #1, add the checks, but improve the abstract API with smart fast + paths for dict and OrderedDict, and refactor CPython to use the abstract + API. Improvements to the abstract API would be valuable regardless. + +Adding the checks to the concrete API would help make any interpreter +switch to OrderedDict less painful for extension modules. However, this +won't work. The equivalent C API call to `dict.__setitem__(obj, k, v)` +is 'PyDict_SetItem(obj, k, v)`. This illustrates how subclasses in C call +the base class's methods, since there is no equivalent of super() in the +C API. Calling into Python for parent class API would work, but some +extension modules already rely on this feature of the concrete API. + +For reference, here is a breakdown of some of the dict concrete API: + +========================== ============= ======================= +concrete API uses abstract API +========================== ============= ======================= +PyDict_Check PyMapping_Check +(PyDict_CheckExact) - +(PyDict_New) - +(PyDictProxy_New) - +PyDict_Clear - +PyDict_Contains PySequence_Contains +PyDict_Copy - +PyDict_SetItem PyObject_SetItem +PyDict_SetItemString PyMapping_SetItemString +PyDict_DelItem PyMapping_DelItem +PyDict_DelItemString PyMapping_DelItemString +PyDict_GetItem - +PyDict_GetItemWithError PyObject_GetItem +_PyDict_GetItemIdWithError - +PyDict_GetItemString PyMapping_GetItemString +PyDict_Items PyMapping_Items +PyDict_Keys PyMapping_Keys +PyDict_Values PyMapping_Values +PyDict_Size PyMapping_Size + PyMapping_Length +PyDict_Next PyIter_Next +_PyDict_Next - +PyDict_Merge - +PyDict_Update - +PyDict_MergeFromSeq2 - +PyDict_ClearFreeList - +- PyMapping_HasKeyString +- PyMapping_HasKey +========================== ============= ======================= + + +The dict Interface Relative to OrderedDict +========================================== + +Since OrderedDict subclasses dict, understanding the various methods and +attributes of dict is important for implementing OrderedDict. + +Relevant Type Slots +------------------- + +================= ================ =================== ================ +slot attribute object dict +================= ================ =================== ================ +tp_dealloc - object_dealloc dict_dealloc +tp_repr __repr__ object_repr dict_repr +sq_contains __contains__ - dict_contains +mp_length __len__ - dict_length +mp_subscript __getitem__ - dict_subscript +mp_ass_subscript __setitem__ - dict_ass_sub + __delitem__ +tp_hash __hash__ _Py_HashPointer ..._HashNotImpl +tp_str __str__ object_str - +tp_getattro __getattribute__ ..._GenericGetAttr (repeated) + __getattr__ +tp_setattro __setattr__ ..._GenericSetAttr (disabled) +tp_doc __doc__ (literal) dictionary_doc +tp_traverse - - dict_traverse +tp_clear - - dict_tp_clear +tp_richcompare __eq__ object_richcompare dict_richcompare + __ne__ +tp_weaklistoffset (__weakref__) - - +tp_iter __iter__ - dict_iter +tp_dictoffset (__dict__) - - +tp_init __init__ object_init dict_init +tp_alloc - PyType_GenericAlloc (repeated) +tp_new __new__ object_new dict_new +tp_free - PyObject_Del PyObject_GC_Del +================= ================ =================== ================ + +Relevant Methods +---------------- + +================ =================== =============== +method object dict +================ =================== =============== +__reduce__ object_reduce - +__sizeof__ object_sizeof dict_sizeof +clear - dict_clear +copy - dict_copy +fromkeys - dict_fromkeys +get - dict_get +items - dictitems_new +keys - dictkeys_new +pop - dict_pop +popitem - dict_popitem +setdefault - dict_setdefault +update - dict_update +values - dictvalues_new +================ =================== =============== + + +Pure Python OrderedDict +======================= + +As already noted, compatibility with the pure Python OrderedDict +implementation is a key goal of this C implementation.

For a linked-list implementation, as +with some other implementations, that situation may lead to undefined +behavior. The documentation for dict mentions this in the `iter()` section +of http://docs.python.org/3.4/library/stdtypes.html#dictionary-view-objects. +In this implementation we follow dict's lead (as does the pure Python +implementation) for __iter__(), keys(), values(), and items(). + +For internal iteration (using _odict_FOREACH or not), there is still the +risk that not all nodes that we expect to be seen in the loop actually get +seen. Thus, we are careful in each of those places to ensure that they +are. This comes, of course, at a small price at each location. The +solutions are much the same as those detailed in the `Situation that +Endangers Consistency` section above. + + +Potential Optimizations +======================= + +* Allocate the nodes as a block via od_fast_nodes instead of individually. + - Set node->key to NULL to indicate the node is not-in-use. + - Add _odict_EXISTS()? + - How to maintain consistency across resizes?
