Why not using the hash when comparing strings?
by Victor Stinner Oct. 19, 2012

Oct. 19, 2012

Hi, I would like to know if there a reason for not using the hash of (bytes or unicode) strings when comparing two objects and the hash of the two objects was already been computed. Using the hash would speed up comparaison of long strings when the two strings are different. Something like: if ((op == Py_EQ || op == Py_NE) && a->ob_shash != -1 && b->ob_shash != -1 && a->ob_shash != b->ob_shash) { /* strings are not equal … [View More]

PEP 425 comment: package names
by martin＠v.loewis.de Oct. 18, 2012

Bumping autoconf from 2.68 to 2.69
by Trent Nelson Oct. 17, 2012

Oct. 17, 2012

Any objections to regenerating configure with autoconf 2.69? The current version is based off 2.68, which was release on the 22nd of September 2010. 2.69 was released on the 24th of April, 2012. (There are some fixes for the more esoteric UNIX platforms that Snakebite will benefit from. Also, I struggled to find a box with 2.68 even installed when I needed to regenerate configure this weekend; it seems all package management/ports have bumped to 2.69.) … [View More]

PEP 429, Release Schedule for Python 3.4, posted

It's essentially identical to the draft I posted last week--nothing new there. Looking forward to February 2014! And, to quote Barry Warsaw, let the wild rumpus begin!, //arry/
