MPs do not show all replacement commits following a force push

[Robie Basak]

If I force push to the source branch of an existing MP, then some new commits are displayed, but not all of them.

For example, in https://code.launchpad.net/~racb/git-ubuntu/+git/usd-importer/+merge/424877, I force pushed an entire replacement branch since I amended the first commit of a series of commits. But the MP mentions only the addition of a single commit.

It happens that my replacement branch contains one additional commit. Did Launchpad just count the commits and assume that I only added on to the end?

Expected result: the entire set of replacement commits are presented in the history. Perhaps, if commits have disappeared as well as new ones being added, this should be mentioned, too.

I found I'd already filed bug 1849306 which is related, but this issue is that what is already being presented is misleading, whereas the other is a request to improve UX in case of a force push.

Thanks for this detailed report.

We had a quick look at it, and there might be an issue in the implementation for comment/commit interleaving.
