> destroying Commit information just to keep the graph tidy is a bad idea in my opinion

The commit information I see when telling teams to squash their branches on merge is not valuable.

* "fixing whitespace" * "incorporate review comments" * "fix broken test" * "fix other broken test"

(note, the broken tests were broken by the changes in the PR)

As soon as that PR is merged those commits are worthless. And there are branches with dozens of those "fixing X" commits that would otherwise pollute the commit graph.

Things like this should not be standalone commits though, they should be incorporated into the previous branch by amending the original work. It takes some effort to have a useful git history, it does not just happen on its own.

Sounds like six vs half-dozen. Why does it matter if somebody amends vs squashes?

[gray_-_wolf]

It does not matter if you have one commit. If your change is split into few commits for increased readability, in that case it does matter.

Do you really believe that if, for example, this change to btrfs filesystem https://lore.kernel.org/linux-btrfs/cover.1699470345.git.jos... would be squashed, nothing of value would be lost?

You can very easily rewrite your commit message on GitHub when squash merging. Since the organizations I work exclusively use squash merge, I often just update the commit to be more valuable, listing the important changes it contains. (And of course the PR in GitHub will contain the commit history of the branch that was squashed, as well as any discussion.)

IMO, this is a lot simpler and easier to do than rebasing your branch to have a flawless history.

I rather strongly disagree here.

Having whitespaces mucks up commit, causing you to lose focus of what's actually important.

I have `git blame` aliased to `git blame -w` which ignores whitespace-only changes.

You can also reblame when you come across this formatting commits.

Yep, intermediate commits on a branch tend to be completely worthless. I'd much rather have "git blame" point to the commit that contains the entire change together.

[dieselgate]

Agree strongly, it's nice in theory to view the intermediate commits but in practice have never needed to look at them

[lelandfe]

Those commits would be the bathwater one casts out alongside the useful commits in using squash merges.

[diek]

If the useful commits are the "baby" in your bathwater analogy, all the useful information in those commits is in the squashed commit.

This assumes a branch being merged in represents one logical change (a feature/bugfix/etc) that is "right sized" to be represented by one commit.

[mablopoule]

Yes, but now it's mixed with the bathwater, and now morph into another metaphor as it become the needle in the haystack.

It's okay to have 'low information' commits one can easily ignore in your history, as long as the 'high information' ones stay readable and coherent.

[26fingies]

You can usually see that in whatever tool youre using anyway. Blame -> find the PR -> see commit history.
