234fb2d503 Issue 21424: Apply the nlargest() optimizations to nsmallest() as well. 2014-05-11 14:21:23 -07:00
Raymond Hettinger
277842eff1 Issue #21424: Optimize heaqp.nlargest() to make fewer tuple comparisons. 
Consolidates the logic for nlargest() into a single function so that
decoration tuples (elem,order) or (key, order, elem) only need to
be formed when a new element is added to the heap.  Formerly, a tuple
was created for every element regardless of whether it was added to
the heap.

The change reduces the number of tuples created, the number of ordering
integers created, and total number of tuple comparisons.

Issue #21435: Segfault in gc with cyclic trash
Changed the iteration logic in finalize_garbage() to tolerate objects vanishing
from the list as a side effect of executing a finalizer.

db067af12a Issue #21233: Add new C functions: PyMem_RawCalloc(), PyMem_Calloc(), 
PyObject_Calloc(), _PyObject_GC_Calloc(). bytes(int) and bytearray(int) are now
using ``calloc()`` instead of ``malloc()`` for large objects which is faster
and use less memory (until the bytearray buffer is filled with data).

764662020b #15840: make docs consistent by saying operations on closed files raise ValueError. 
Patch by Caelyn McAulay.

Neither Caelyn nor I could find any cases in 2.7 or 3.4/5 where an
operation on a closed stream raised IOError; generally the C
implementations have a macro to check for the stream being closed, and
these macros all raised ValueError.  If we find any, a new bug should
be opened.
