From b67dc062ae9c689f0453d46bba47ceba832f676f Mon Sep 17 00:00:00 2001 From: ticktock35 Date: Sun, 14 Dec 2008 23:19:43 -0500 Subject: opkg: apply "2-pkg-vec--Optimize-gross-inefficiency.patch" from OpenEmbedded pkg_vec: Optimize gross inefficiency. This module tries to implement *unique* vector (without duplicating objects), and does this by iterating thru all already existing elements. Thus, complexity of adding N elements was O(N^2). However, there're no grave reasons to do uniqueness at all: 1. First of all, if feeds are correct, there won't be duplicates. 2. Then, even if there will be, there won't be serious problems like segfaults. 3. Finally, for quite a few operations vectors is constructed from a hashtable, thus uniqueness is guaranteed (which reduces possible cases of non-uniqueness to values of Depends: and friends). All an all, remove dup check, and make ipkg work order of magnitude faster on a feed with few thousands of packages. git-svn-id: http://opkg.googlecode.com/svn/trunk@18 e8e0d7a0-c8d9-11dd-a880-a1081c7ac358 --- (limited to 'TODO') -- cgit v0.9.1
