From 435ec29bc75fc9efd81472ce2f53d081f8be14b8 Mon Sep 17 00:00:00 2001 From: Chantry Xavier Date: Sat, 12 Jan 2008 21:27:13 +0100 Subject: libalpm/sync.c: don't duplicate packages for the sync->data field. Packages put in the sync->data field were always duplicated with pkg_dup, and then freed, This is not needed. Killing this duplication of packages made the memory usage during base reinstall go from 10.4 MB to 8.1 MB.
