From ccc1c731529de16f6fa4064fd992a8f63d7cfc26 Mon Sep 17 00:00:00 2001 From: Dan McGee Date: Fri, 11 Jan 2008 00:01:58 -0600 Subject: Use dynamic string allocation in package structures This also affects all structures with static strings, such as depmiss, conflict, etc. This should help a lot with memory usage, and hopefully make things a bit more "idiot proof". Currently our pactest pass/fail rate is identical before and after this patch. This is not to say it is a perfect patch- I have yet to pull valgrind out. However, this should be quite safe to use in all situations from here on out, and we can start plugging the memleaks.
