Yes, but the purpose of the issue is to enable its constructor. You cannot
instanciate a DictProxy in Python 2:
import types
types.DictProxyType
type 'dictproxy'
types.DictProxyType({})
Traceback (most recent call last):
File stdin, line 1, in module
TypeError: cannot create 'dictproxy' instances

[issue14386] Expose dictproxy as a public type
STINNER Victor victor.stin...@gmail.com added the comment: Patch version 4, it is ready for a review. Summary of the patch: - expose the internal dict_proxy() type (used for __dict__ of user classes) as types.MappingViewType (it was exposed a types.DictProxyType in Python 2) - repr(types.MappingViewType) returns 'mappingview(...)' instead of 'dict_proxy(...)' - implement mappingview.__new__() - mappingview constructors (mappingview.__new__() and PyDictProxy_New) rejects sequences - Keep PyDictProxy_New() and PyDictProxy_Type names for backward compatibility - mappingview_contains() calls PySequence_Contains() for types other than dict (instead of PyDict_Contains) - Write a doc and a lot of tests - Rename the internal dict attribute to mapping (this change may be reverted if it impacts backward compatibility) I added the new tests to test_descr. Is test_types a better place for these types (the type is exposed in the types module, but implemented in descrobject.c)? I leaved the object implementation in descrobject.c to not have to add a new short file and to keep the Mercurial history. The file does still contain this funny comment: /* This has no reason to be in this file except that adding new files is a bit of a pain */ MappingViewType constructor accepts any mapping: dict, collections.ChainMap, ... Sequences are rejected: tuple, list, dict_view, etc. -- Added file: http://bugs.python.org/file25063/mappingview-4.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue14386 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue14386] Expose dictproxy as a public type
Guido van Rossum gu...@python.org added the comment: I'd like to bikeshed a little on the name. I think it should be MappingProxy. (We don't use view much but the place where we do use it, for keys/values/items views, is very different I think. Also collections.abc already defines MappingView as the base class for KeysView and friends.) Also make sure there's no way for someone who has access to the proxy to get to the underlying mapping; preventing that access is the explicit purpose of the original dict_proxy type. You might even add a comment to this effect to the code, so someone doesn't accidentally add it in the future. Perhaps in the proxy_methods structure or in the type structure just before tp_members. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue14386 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue14386] Expose dictproxy as a public type
STINNER Victor victor.stin...@gmail.com added the comment: (We don't use view much but the place where we do use it, for keys/values/items views, is very different I think.) You are right, it's closer to a proxy because it has the same methods than a mapping (except of some methods used to modify a mapping), whereas the API of keys/values/items views is very different from the mapping API. Also collections.abc already defines MappingView as the base class for KeysView and friends.) MappingView is a strange ABC: it should probably declare __contains__ as an abstract method. I don't see why it doesn't inherit from Set (which would avoid the need of declaring __contains__, Set is a Container) whereas KeysView, ItemsView and ValuesView do inherit from Set. I suppose that MappingView is also present to factorize code but it should not be used directly. Anyway, you are not the first one who remarks that we already use view to define something else, so I wrote a new patch to use the mappingproxy name (exposed as types.MappingProxyType). Also make sure there's no way for someone who has access to the proxy to get to the underlying mapping; I don't think that we can write unit tests for such property. I suppose that the comment below is enough. You might even add a comment ...

I fixed the doc to indicate that mappingview methods operate on the *underlying mapping*. I also added test_views() test.

Raymond Hettinger raymond.hettin...@gmail.com added the comment: The weakref collections objects (sets, dicts, etc) were all put in a separate module and that has worked out well. I suggest doing the same for proxy objects. In maintaining the itertools module, I learned long ago that adding new tools to the module made the whole module more difficult to use (increasing the number of choices increases the complexity of choosing the correct tool). I believe that same also applies to the collections module and have been very reserved about adding new types there. ISTM that exposing internal types such as dict_proxy or bound/unbound methods could be collected together or that various proxy types and tools could be collected together. I don't feel that dict_proxy belongs with namedtuple, deques, or OrderedDicts. As the module maintainer, I request that dict_proxy be put elsewhere. Of course, as BDFL you are free to override that request. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue14386 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

My sandbox only needs the issue #14385, pysandbox can implement its own dictproxy class. If the issue #14385 is accepted, pysandbox can use any mapping, even a mapping implemented in Python!

Enthought's Python Distribution isn't shy about adding tools when they have a demonstrated need. Likewise, Django adds any reusable tools they need. Neither have a dict proxy. I've never run into a use case for it and haven't seen any feature requests for it. PyPi doesn't have package for it (at least not one with any uptake). The languages doesn't *need* this, nor do the other implementations which are trying to keep up with CPython. Guido may let you put in it, but that doesn't mean you should.

If the dict referenced by the dictproxy is modified, the dictproxy is also modified. dictproxy implementation supports any mapping, it is not specific to dict. It would be interesting any mapping, collections.ChainMap for example. The problem is to reject sequence in dictproxy constructor. The PyMapping_Check(dict) !PyMapping_Check(dict) fails on ChainMap. type.__new__(ChainMap) fills tp_as_sequence-sq_item slot is defined because ChainMap has a __getitem__ method. Accepting sequences would be a bad idea because dictproxy(sequence)[missing_key] raises IndexError instead of KeyError.
