From c244cfecf654d34032585530f00d68501ec63d77 Mon Sep 17 00:00:00 2001 From: Dan McGee Date: Mon, 12 Nov 2007 23:01:14 -0600 Subject: Move alpm_splitdep usage to db_read Holy inefficient batman! For a pacman -Qt operation (when we are using compute_requiredby and not database entries), splitdep was being called ~1.3 million times on my local database. By splitting when we read the DB, we drop this number to around 1700 and save a LOT of time in doing so (a 5x increase in pacman -Qt speed here). Note that the depends alpm_list_t in the package struct is no longer a string list, but a list of pmdepent_t objects.
