From a65ad4efc1102449a087b464d3b8d4670a614b99 Mon Sep 17 00:00:00 2001 From: Dan McGee Date: Tue, 14 Aug 2007 10:14:35 -0400 Subject: package.h: implement origin_data union in pmpkg_t struct We were using a void *data element in pmpkg_t before, which is unsafe by its nature of being untyped. Reimplement data as origin_data being a union that can hold either a path to a package file or a pointer to a cache database, and make the other necesary updates in the code to reflect this. See package.h for details.
