I think it would be great to be able to amend changesets, however not at the cost of rewriting history. I'd prefer an approach like Fossil's where modifications to existing records are performed by adding new records.

I agree with Rupert. Just ran into that exact use case. I just checked in some changes and realized I missed a few other changes which I'll have to add to as a separate commit. It would be great to be able to amend commits that haven't been pushed to the server.

Is there even any difference between local and pushed changes if there is no amend / reset function? I'm really hoping that something like that will be added.

I'd like to be able to amend the latest changeset, at least when in distributed mode when it's not been pushed to a central server yet. I can see the value of immutable history but doesn't feel so critical when the history hasn't been shared yet.

It might be nice if amend commits were treated as a purely visual thing, while internally still treating each amend as an individual commit.
So essentially what it does is hide a bunch of nodes inside a single node, with a different description. This way, if someone works on or branches from one of those nodes, nothing breaks.

This could even add another useful feature: Select a couple of nodes and (visually) squash them into one. I'd love to be able to logically clean up our timeline at the end of the week.
And the opposite: Opening up such a node and looking at the individual commits that went into it.

There are some situations where I like to use branches to save pending work (as shelve or git stash). I prefer this workflow from shelve or git stash because it keeps track of the parent so I can revert to the exact same state I was. Also I like being able to see all my pending work in the branch explorer.

Unfortunately, save current work in a branch give a WIP changeset which often does not contains meaningful description and valid content. I wish it does not appear in the history.

I would like to be able to amend and rewrite history for at least "my private changeset": changeset only on my local computer or pushed on the server but nobody can see except me or my approval (similar to mercurial 'phase' feature).

I like history immutability but sometimes I just check-in something wrong (forgot to add a couple of files) so I would like to change latest changeset of my branch.

It works okay in Git because you can amend before pushing to the server. But in Plastic SCM it should rewrite the history :(

Personally, I value immutable history highly. I would appreciate an amend feature as long as it does not complicate questions like 'does my colleague have the latest changes from branch X in their current workspace' and 'what was the exact set of input files when build Y was produced'.

We find that working with per-task branches, it is not a problem to have extra commits for amends. It is when working on a single branch (usually directly on main) that amend operations would be valuable to us. Therefore, we try to use task branches as much as possible.

Hi Rober! :P

Rewriting history is one of the cool features in Git, but it is somehow counter intuitive in the commercial software development world where you would like version control history to be immutable.

That being said, sounds like a cool thing to do.

Now, is your graph correct? I mean, what D-E-F have to do here? Not sure if I'm missing something.
