- Refactor _dedup_item, _write_item, and _undo_write methods to use
higher-level abstractions (_DedupResult and _WriteResult classes).
- Add internal _OnDup class to bundle (on_dup_key, on_dup_val, on_dup_kv)
together into a single abstraction. Signatures of methods like _put and
_update are cleaner as a result.
- Add the "_NOOP" _DedupResult abstraction.
- Make _Marker extend namedtuple, no need for it to be mutable.
- Enable the pylint messages that were disabled now that the code is cleaner.
- Make DuplicationPolicy extend _Marker and make RAISE, OVERWRITE, and
IGNORE instances of DuplicationPolicy once again. This time deprecate
access via DuplicationPolicy.(IGNORE|RAISE|OVERWRITE) to prevent
infinite chaining.
- Misc. code and docs improvements.
- Make :func:`bidict.FrozenOrderedBidict.__iter__` slightly more efficient.
- :func:`~bidict.frozenbidict.__repr__` no longer dynamically checks
for a ``__reversed__`` method to determine whether to use an ordered or
unordered ``__repr__`` delegate. Now it always just calls the new
:func:`~bidict.frozenbidict.__repr_delegate__` instead, which may be
explicitly overridden as needed.
including:
- simplify type hierarchy, merging the frozen types into the base types
- upgrade to latest hypothesis (3.38.0)
- use Reversible for order-sensitive FrozenOrderedBidict.__eq__
- fix bug where bidict._on_dup_kv was not set to ON_DUP_VAL as documented
- drop leading underscore from attrs that should be public
- improve setup.py/metadata
- rename DuplicationBehavior -> DuplicationPolicy
- drop ON_DUP_VAL duplication policy in preference to just using None
- reduce ordered bidict memory usage and speed up copy
- support Python 3.6, refactor CI/test setup, increase test coverage
- refactor BidirectionalMapping, BidictBase, OrderedBidictBase,
FrozenBidictBase, and subclasses
- move frozenorderedbidict into _frozen and looseorderedbidict into _loose
- register bidict as a virtual subclass of MutableMapping rather than
inheriting from it directly. This makes it clearer that it does not use any
of the concrete generic methods that MutableMapping provides.
- improve performance and flexibility of frozenbidict and
frozenorderedbidict hashing
- docs, including new type-hierarchy.png diagram
- rm unused imap, ifilter, izip_longest from compat, add PYPY
- update to latest versions of dependencies
- restore benchmarking on travis
