py-multidict: updated to 6.8.0

6.8.0

Bug fixes

- A segmentation fault that could be triggered when getting an item is now fixed

- Fixed reference leak in iterators, views and ``istr``

- Fixed the pure-Python :class:`~multidict.MultiDict` constructor and
  :py:meth:`~multidict.MultiDict.extend`,
  :py:meth:`~multidict.MultiDict.update`, and
  :py:meth:`~multidict.MultiDict.merge` methods over-allocating their
  internal hash table when called with both a positional argument and
  keyword arguments, because keyword arguments were counted twice in the
  size estimate

- Fixed ``__repr__`` of :class:`~multidict.MultiDict`,
  :class:`~multidict.CIMultiDict`, their proxies, and the keys/items views
  producing invalid output when keys contained quote characters --
  keys are now formatted with :func:`repr` so the result is a valid Python
  string literal

- Fixed a segfault when calling :py:meth:`~multidict.MultiDict.add` with only one of its two required arguments supplied by keyword, e.g. ``d.add(key="k")``. Extra keyword arguments passed to the 
lookup and removal methods are also now rejected with :exc:`TypeError` instead of being silently ignored.

- Fixed a segfault when constructing a multidict iterator type directly, e.g. ``type(iter(md.keys())).__new__(...)``. Such an iterator had a NULL internal pointer that ``next()`` dereferenced. The 
iterator types now forbid direct instantiation, the same way the view types were fixed in :issue:`1163`.

- Fixed a segfault when using a :py:class:`~multidict.MultiDict` or :py:class:`~multidict.CIMultiDict` created via ``__new__`` without calling ``__init__`` (for example a subclass that does not call 
``super().__init__()``). The internal state was left as NULL pointers that the first method call dereferenced. ``tp_new`` now initializes the object to a valid empty mapping.

- Fixed two crashes in the C extension caused by holding a raw pointer into a hash table across an operation that could reshape it. Updating a multidict from itself (e.g. ``d.extend(d)``) freed the 
very table being iterated -- a use-after-free; ``extend(self)`` now doubles the contents and ``update(self)``/``merge(self)`` are no-ops. Building a multidict from a list of pairs whose 
case-insensitive key ``.lower()`` shrinks that list read past the end of the list; the length is now re-checked on every iteration.

- Fixed three reference/resource leaks on error paths in the C extension: the items-view ``__contains__`` leaked the first element of a candidate pair when reading the second one raised; ``__repr__`` 
leaked its ``PyUnicodeWriter`` when the multidict was mutated during iteration; and the internal iteration helper leaked the identity reference when key materialization failed under low memory.

- Stopped several feature-detection fallbacks in the C extension from swallowing every exception. When probing an argument (``arg.items()``/``arg.keys()``) or measuring it (``len(other)``) fails, the 
code now clears only the expected :exc:`TypeError`/:exc:`AttributeError` and lets everything else -- notably :exc:`MemoryError` and :exc:`KeyboardInterrupt` -- propagate, matching the already-correct 
sites elsewhere in the module.

- Fixed a segmentation fault when extending a multidict with itself

- Fixed a memory leak when ``MultiDict`` and ``CIMultiDict`` instances are
  initialized more than once

- Fixed a reference leak in items-view set operations

- Fixed a memory leak when destroying C-extension multidict instances
  and proxies

- Fixed a reference leak from repeated ``__init__`` calls on
  ``MultiDictProxy`` and ``CIMultiDictProxy`` instances

- Fixed missing decref for :data:`None` on error in :meth:`~multidict.MultiDict.setdefault`

Features

- Added :py:func:`reversed` support to the keys, values, and items views of
  :class:`~multidict.MultiDict`, :class:`~multidict.CIMultiDict`, and their
  proxies in both the C-extension and pure-Python implementations

- Optimized key identity comparison for C Extension.

  Now it uses fast path that is equal to :c:func:`PyUnicode_Equal` from
  Python 3.14+ but without redundant type checks. It gives ~15% speed-up on benchmarks with many key comparisons.

- Changed both the pure-Python and C implementations to mark a temporarily
  removed hash table entry by setting the high bit of its hash instead of
  overwriting it with a sentinel value, so restoring the entry no longer
  recomputes the hash; :meth:`~multidict.MultiDict.getall` is faster ~10% now in C version
