I’d still like a deeper dive into how database corruption led to data restoration
It seems like deleting a photo must just be removing the entry from the SQLite database, and not actually deleting the photo?
Media library apps have been doing this kind of stuff forever. An index of the files + metadata allows for a better and more performant experience. But, if an entry in the DB gets pooched, file remains on the drive and is hidden from the user.
Many media library apps actually have a way to repair and or rebuild the library DB if it gets out of sync or corrupted. iTunes straight up put that feature in the menu bar. The Photos app will do it if you launch the app while holding command-option.
Back when iPods were king, how many of us had old music come back to life after a fucked up iTunes library was rebuilt? It’s kind of a similar issue.
Sure, an index makes sense for quick search, but I’m confused why deleting it wouldn’t remove it from the filesystem too
Is that why iPhones seem to have no idea how much disk space they’re using?
Given the rarity of this, it could’ve just been the normal random stuff that happens in computer land. Requests that don’t complete because they were interrupted by a crash, the rare bad block, etc. Or maybe it was just a bug that occasionally reared its head under certain circumstances.
Whatever it was, it wasn’t the first time a piece of software had an index that was messed up and out of sync with the stored files.
As for the iPhone storage thing you mentioned, I don’t know what you’re talking about. There was a IOS 17 bug early on where people mentioned that the OS needed a restart to claw back space from temporary install files and caches.
That said, the corrupted DB we’re talking about appears specific to the photos app. It’s not the file system index. It’s basically a glorified preference file.
@Valmond @ozymandias117 oh so we’re still doing the baseless-accusation-without-knowing-how-it-works thing?
They keep deleted photos for a time in iCloud in case someone comes looking for them
Every cloud storage provider does it, every mail server does it, it’s incredibly commonplace
