Bug fixes

• Fixed a regression in 7.2.0 where a subclass of
  :class:~multidict.MultiDictProxy or :class:~multidict.CIMultiDictProxy
  that converted its argument in its own __init__() raised
  :exc:TypeError before that __init__() ran; such a subclass got an
  empty multidict until its __init__() set the proxied one

v7.2.0

Compare Source

=====

(2026-10-23)

7.2.0 drops Python 3.10, fixes a crash in a proxy built without
__init__() and a :exc:MemoryError from a huge __length_hint__(),
and is otherwise a performance release for the C extension: lookups,
adds, updates and deletes each needed a few percent fewer instructions.

Bug fixes

• Stopped a huge __length_hint__() from raising :exc:MemoryError in
  :meth:~multidict.MultiDict.extend, :meth:~multidict.MultiDict.update
  and :meth:~multidict.MultiDict.merge; the C extension capped the room
  it reserved for the hint at the largest table the constructor allocates
  up front -- by :user:asvetlov.

• Fixed a segmentation fault when using a :class:~multidict.MultiDictProxy
  or :class:~multidict.CIMultiDictProxy built by __new__() without
  __init__(); __new__() started requiring the proxied multidict, the
  same argument as the constructor -- by :user:asvetlov.

Features

• Sped up reading a multidict in the C extension. md[key],
  :meth:~multidict.MultiDict.get and :meth:~multidict.MultiDict.getone
  became up to 7% faster by returning the lookup's result by value instead
  of through a pointer to the caller's local, which had made
  -fstack-protector-strong add a stack canary to every call. On the GIL
  build a :meth:~multidict.MultiDict.get miss became 5% faster and
  key in md inlined its hash table lookup. On the free-threaded build
  :meth:~multidict.MultiDict.getall stopped taking the multidict's lock
  for a multidict without repeated keys, the way
  :meth:~multidict.MultiDict.get already avoided it. len(md.keys())
  and iterating over the keys of a multidict that holds a key more than
  once became 4% to 13% faster -- by :user:asvetlov.

• Sped up building and updating a multidict in the C extension. On the GIL
  build, constructing a multidict from a sequence of pairs needed 8% to 10%
  fewer instructions and :meth:~multidict.MultiDict.update 3.5% to 4.5%
  fewer. On the free-threaded build, building a
  :class:~multidict.MultiDict became up to 14% faster, since a table that
  is both full and unable to hold the new key in its compact form was grown
  and moved in one rebuild, and :meth:~multidict.MultiDict.add,
  md[key] = value for a new key and
  :meth:~multidict.MultiDict.setdefault needed 2% to 3% fewer
  instructions, about 1% fewer on the GIL build. Updating a multidict with
  existing keys needed 1.5% to 2.9% fewer instructions, while adding a new
  key needed about 0.5% more on the GIL build -- by :user:asvetlov.

• Sped up replacing and removing items in the C extension.
  :meth:~multidict.MultiDict.add, :meth:~multidict.MultiDict.getall,
  md[key] = value and del md[key] stopped computing the identity
  of a key that, or whose :class:~multidict.istr canonical form, already
  serves as one, as md[key] did, and checked a
  :class:~multidict.CIMultiDict key holding uppercase letters only once.
  On the GIL build del md[key] needed 4% to 5% fewer instructions,
  md[key] = value about 2% fewer and :meth:~multidict.MultiDict.pop
  1% fewer. Replacing a key that had duplicates needed 0.8% to 1.7% fewer
  instructions, and :meth:~multidict.MultiDict.clear became 6% faster on
  the free-threaded build -- by :user:asvetlov.

Removals and backward incompatible breaking changes

• Dropped support for Python 3.10 as it has reached end of life
  -- by :user:asvetlov.

Improved documentation

• Refreshed the instruction-count tables in the benchmarking reference
  against the current tree -- by :user:asvetlov.

Packaging updates and notes for downstreams

• Added the CPython 3.15 trove classifier and started testing the
  GIL and free-threaded 3.15 builds in CI -- by :user:asvetlov.

Contributor-facing changes

• Split the release publishing and signing across four parallel jobs, so
  that each one finishes well within the lifetime of its short-lived PyPI
  upload token -- by :user:asvetlov.

  :issue:1768, :issue:1822.

• Changed the clear() benchmarks to clear a thousand prebuilt
  multidicts of 0 to 99 items each, copied outside the measured region,
  since the copy inside the timed loop and the single small table it
  measured made the result swing by up to 19% between runs of the same
  commit -- by :user:asvetlov.

• Pinned Hypothesis in the MyPy pre-commit hooks and dropped a
  type: ignore comment from the Hypothesis tests that became unused
  once Hypothesis annotated run_state_machine_as_test(), which failed
  the MyPy lint job -- by :user:asvetlov.

• Fixed a test of a huge __length_hint__() failing on 32-bit builds,
  where its 2**40 hint did not fit a Py_ssize_t
  -- by :user:asvetlov.

Miscellaneous internal changes

• Split the C extension's helpers per table kind, so that the lookup
  loops of pop(), popall(), item replacement and update(), the
  table rebuild and the deferred delete of an entry call the helper for
  their own kind instead of testing it again, and moved the choice between
  overwriting and dropping each entry of a repeated key into the per-kind
  loops of update(). Folded helpers with a single caller into that
  caller: choosing the kind of a new table, reading a compact entry's
  identity and hash, filling a new entry, replacing a key's values,
  deleting a key and looking up the first value of a key that needs a
  computed identity. Merged the two per-kind checks for a deleted entry
  into one, and removed the separate watched copies of delete, pop and
  replace, folding the add that follows a missed replace into the replace
  itself -- by :user:asvetlov.

  :issue:1810, :issue:1811.

• Removed duplicated code from the C extension: the (key, default)
  methods shared their argument parsing and missing-key result, and one
  macro each replaced the copies of the lock-free compact entry match on
  the free-threaded build and of the per-kind dispatch of a single key
  lookup. Turned the watcher record, flush and pending check helpers and
  _growth_rate() into macros, so that a multidict without watchers
  skipped evaluating the event arguments, renamed the lowercase
  function-like macros to upper case, and dropped the leading underscore
  from the watcher functions that the macros call from other headers
  -- by :user:asvetlov.

• Adjusted how the C extension spends GCC's inlining budget: marked most
  checks that lead to a raised exception as unlikely, so the compiler
  moves the error paths out of the hot code, kept the event name lookup of
  a failing watcher callback report and the cleanup of a dropped watcher
  event log out of line, and dropped the inline hint from the helpers
  that compute a table's size and that rebuild, build or free a table's
  keys -- by :user:asvetlov.

• Moved the C extension's repr() of multidicts, proxies and views and
  its equality comparison out of the hash table header, each into a header
  of its own -- by :user:asvetlov.
