Raymond Hettinger ade08ea8a8 Add news entries for the dictionary optimizations. 2004-03-18 09:48:12 +00:00
Raymond Hettinger b7d05db0be Optimize tuple_slice() and make further improvements to list_slice() 
and list.extend().  Factoring the inner loops to remove the constant
structure references and fixed offsets gives speedups ranging from
20% to 30%.
 2004-03-08 07:25:05 +00:00
Raymond Hettinger dd80f76265 SF patch #910929: Optimize list comprehensions 
Add a new opcode, LIST_APPEND, and apply it to the code generation for
list comprehensions.  Reduces the per-loop overhead by about a third.
 2004-03-07 07:31:06 +00:00
Raymond Hettinger 31017aed36 SF #904720: dict.update should take a 2-tuple sequence like dict.__init_ 
(Championed by Bob Ippolito.)

The update() method for mappings now accepts all the same argument forms
as the dict() constructor.  This includes item lists and/or keyword
arguments.
 2004-03-04 08:25:44 +00:00
Raymond Hettinger 79b5cf1129 Mention the optimization of list.extend(). 2004-02-17 10:46:32 +00:00
Raymond Hettinger ab517d2eac Fine tune the speed/space trade-off for overallocating small lists. 
The Py2.3 approach overallocated small lists by up to 8 elements.
The last checkin would limited this to one but slowed down (by 20 to 30%)
the creation of small lists between 3 to 8 elements.

This tune-up balances the two, limiting overallocation to 3 elements
(significantly reducing space consumption from Py2.3) and running faster
than the previous checkin.

The first part of the growth pattern (0, 4, 8, 16) neatly meshes with
allocators that trigger data movement only when crossing a power of two
boundary.  Also, then even numbers mesh well with common data alignments.

Andrew M. Kuchling 77ad829261 [Bug #780231] One of the changes described in the 2.3 "What's New" document

Andrew M. Kuchling 0ceb9b1603 Change \code to \verb, because TeX merges the two dashes into a 
hyphen, resulting in the output '-list-classifiers', not the correct

 2003-07-16 04:00:14 +00:00
Fred Drake 3605ae5966 In the description of enumerate(), the indexing operators should not

Skip Montanaro 959c7727f4 Add a little more verbiage about the bsddb module/package change. It's 
clear from recent discussions on c.l.py that people are a bit confused about
the differences between the old bsddb, the new bssdb, the bsddb3/PyBSDDB
package and changes to file formats.  Tried to clarify the issues.
