* Issue #21424: Optimize heaqp.nlargest() to make fewer tuple comparisons.Raymond Hettinger2014-05-111-85/+0
| | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | 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.
