From 49176461a6b476e673e232075c95f07963750f74 Mon Sep 17 00:00:00 2001 From: Dan McGee Date: Wed, 7 Jul 2010 09:39:39 -0500 Subject: Unify caching concerns in package accessors Move almost all of the caching related stuff into a single #define (which should maybe even just be a static function) so we don't duplicate logic all over the place. This also makes the code a heck of a lot shorter and means further changes to this stuff don't have to touch each and every getter function.

which requires flushing out several assumptions from around the codebase with regards to usage of the PKG_FROM_CACHE value. Make some changes where required to allow the switch, and now the correct value should be set (via a crude hack) depending on whether a package was loaded as an entry in a local db or a sync db. This patch underwent some big rebasing from Allan and Dan.

The former method of getting the depends list for a package was the following: 1. call alpm_pkg_get_depends() 2. this method would check if the package came from the cache 3. if so, ensure our cache level is correct, otherwise call db_load 4. finally return the depends list Why did this suck? Because getting the depends list from the package shouldn't care about whether the package was loaded from a file, from the 'package cache', or some other system which we can't even use because the damn thing is so complicated. It should just return the depends list. So what does this commit change? It adds a pointer to a struct of function pointers to every package for all of these 'package operations' as I've decided to call them (I know, sounds completely straightforward, right?). So now when we call an alpm_pkg_get-* function, we don't do any of the cache logic or anything else there- we let the actual backend handle it by delegating all work to the method at pkg->ops->get_depends. Now that be_package has achieved equal status with be_files, we can treat packages from these completely different load points differently. We know a package loaded from a zip file will have all of its fields populated, so we can set up all its accessor functions to be direct accessors. On the other hand, the packages loaded from the local and sync DBs are not always fully-loaded, so their accessor functions are routed through the same logic as before. Net result? More code. However, this code now make it roughly 52 times easier to open the door to something like a read-only tar.gz database backend. Are you still reading? I'm impressed. Looking at the patch will probably be clearer than this long-winded explanation.
