I don't think you're answering on the same level of abstraction as Thiago's question. At a high level, the commit has indeed been "replaced", but the commits D and E are both separate entities as far as Git is concerned, it's just that E's parent has been set to C and D isn't reachable from any ref; D is in a dangling state. Try this: cd /tmp git init foo cd foo touch foo git add foo git commit -a -m "Initial commit" touch bar git add bar git commit -a -m "Bar" git log --oneline # output: 2e1c949 Bar 499724c Initial commit git commit --amend # amend the message to be "Bar (edited)" git log --oneline # output: 94e441b Bar (edited) 499724c Initial commit Now look at the log starting from the commit that was amended (2e1c949): git log --oneline 2e1c949 # output: 2e1c949 Bar 499724c Initial commit 2e1c949 still exists and still has its parent set to 499724c, it's just that 2e1c949 is not reachable from, in this case, master. You can see this more explicitly in the log when specifying master and the dangling 2e1c949: $ git log --graph --oneline --decorate master 2e1c949 # two explicit places to start from * 94e441b (HEAD, master) Bar (edited) | * 2e1c949 Bar |/ * 499724c Initial commit The two are separate, as you can see. As far as an actual answer concerning `prune` and `fsck`, I'm not quite sure but it may be something to do with the default length of time before an object will actually be pruned. I'd be interested in reading a fuller answer by someone who knows. -- You received this message because you are subscribed to the Google Groups "Git for human beings" group.
