This tool is a drop-in replacement for git branch --merged which also works when branches are rebased or cherry-picked into HEAD.

go install mvdan.cc/git-picked@latest

It tries to match commits via their Change-Id, if it is present. Otherwise, a hash is used consisting of:

• Author name
• Author email
• Author date (in UTC)
• Commit summary (first line of its message)

Note that the matching is only done with the tip commit of each branch.

Matching is done against the history of HEAD, stopping when either all commits have been found or when the main history dates fall behind the author dates of the commits left to match. This will work nicely as long as noone uses a time machine.

This is a standalone binary and does not depend on the git executable.

Note that this heuristic may get confused with release branches. As such, if you name your release branches release-x.y you likely want to use an alias like:

git-picked | grep -vE '^(master|release|backport)'

Branches with patches targeting branches other than master should also be excluded, like backport-some-feature in this case.
