Question about displaying branches in Git

Question

git

We use git-flow in our work, today it came to a conflict with the authorities that we allegedly are developing not according to the regulations described for this approach. Is there an interface, a program, or something else where you can visually poke to a commit and it will be written there that the given branch in which this commit came from such and such a branch, plus when merging branches, when we click in merge commit, it shows which branch was poured. We use Smartgit, but stubbornly does not see it there and does not want to understand the principle of the graph in git. I will be very grateful.

Answer 1

You can show the tree like this:

log --pretty=format:'%h was %an, %ar, message: %s' --graph

Answer 2

In principle, if simply displaying the tree is enough, you can look at GitExtensions. She beautifully shows the tree with all the manipulations on the branches.
SourceTree still can do the same, but I like its display mode less, although it can do more.

Answer 3

If branches A and B were merged and branch B was deleted, then it is impossible for Git to determine which branch: A or B, or some other, now defunct C, commits were made.
