- Issue #2115: Important speedup in setting __slot__ attributes. Also
|
||||
prevent a possible crash: an Abstract Base Class would try to access a slot
|
||||
on a registered virtual subclass.
|
||||
|
||||
- Fixed repr() and str() of complex numbers with infinity or nan as real or
|
||||
imaginary part.
|
||||
|
||||
- Clear all free list during a gc.collect() of the highest generation in order
|
||||
to allow pymalloc to free more arenas. Python may give back memory to the
|
||||
OS earlier.
|
||||
|
||||
- Issue #2045: Fix an infinite recursion triggered when printing a subclass of
|
||||
collections.defaultdict, if its default_factory is set to a bound method.
|
||||
|
||||
- Fixed a minor memory leak in dictobject.c. The content of the free
|
||||
list was not freed on interpreter shutdown.
|
||||
|
||||
- Limit free list of method and builtin function objects to 256 entries
|
||||
each.
|
||||
|
||||
- Patch #1953: Added ``sys._compact_freelists()`` and the C API functions
|
||||
``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
|
||||
to compact the internal free lists of pre-allocted ints and floats.
|
||||
|
||||
- Bug #1983: Fixed return type of fork(), fork1() and forkpty() calls.
|
||||
Python expected the return type int but the fork familie returns pi_t.
|
||||
|
||||
- Issue #1678380: Fix a bug that identifies 0j and -0j when they appear
|
||||
in the same code unit.
|
