Made Sparkle.h no longer a massive multi-headed abomination: now only SUAppcastItem, SUAppcast and SUUpdater (and SUVersionComparisonProtocol because it's part of the delegate protocol) are public. COMPATIBILITY ISSUE: This means there's no longer a public SUProbingUpdateDriver or a checkForUpdatesWithDriver: method. Now use checkForUpdateInformation. I may change that API before release, though. I'm thinking it might be better to give the delegate the opportunity to reject a potential update instead: then you'd just call checkForUpdatesInBackground and override that delegate method to always return NO. We'll see.
…Sparkle. More super-unstable refactorings to come...
Sparkle now makes sure to make the update alert key when its host app becomes active.
Refactored Sparkle's unarchiving system into SUUnarchiver, a factory for SUPipedUnarchiver and SUDiskImageUnarchiver. I removed that nasty cleanUp call by now copying out the contents of the DMG into the /tmp directory and unmounting. Nice! This changed a fair amount so please test with your build and let me know if it explodes things. Works in my tests, though.
…elaunch tool out of the host before installing the update; that way, we can use the old version's tool. This insures us against future changes in the relaunch method.
…actoring. Please read: - Broke out SUUpdater functionality into update drivers. There's a basic one from which everything else inherits, then a user-initiated one, an automatic one, and a scheduled one. It's super-clean-and-shiny. - Destroyed the abomination that was SUStatusChecker. In its place is SUProbingUpdateDriver, which is like 10 lines long. - Made automatic installation less stupid. It used to install, THEN offer to relaunch. That's dumb, beacuse if the user says no, the app is running from the trash. Now it offers to install and relaunch or to install on quit. - Renamed like every method and symbol. I hope you didn't branch anything. - Reorganized the project hierarchy to be much clearer and easier to navigate. - Reworked the error system to no use NSError instead of exceptions; extra technical information is now logged to the console so that we can find problems. - A bunch of other small bugfixes in things I noticed along the way but no longer remember. - Probably a ton of other stuff. Read over the code and see what I've done. Then PLEASE test this with your app internally and let me know how it goes. This revision is hereby NOT YET DECLARED SAFE FOR PUBLIC RELEASE. But because I'm still using SVN, this is how things have to be.
