How could I list commits in a pull request or feature branch?

[yanOnGithub]

I tried a lot of these.
https://www.google.com/search?q=git+show+commits+on+a+feature+branch

Let's use this as an example:
https://github.com/go-gitea/gitea/pull/7089/commits

There are 7 commits in this PR. Suppose I am standing in the head of the feature branch after running one of the following
git checkout "mrsdizzie:fix-7068"
git checkout 177092a

Is there any way to list the 7 commits on CLI? Any git commands? Any shell scripts? Any wget/curl/REST API?

Further question: Suppose I am in the middle (cbfc6aa), can I list the 4 commits starting from 8263e09?

ok, you can find the merge-base of the branch and the master

git merge-base master HEAD

Then you do:

git log $MERGE_BASE..HEAD

So all together:

git log $(git merge-base master branch-name)..branch-name

#7117 (comment)
git merge-base master HEAD
git log $(git merge-base master branch-name)..branch-name

I tried "git merge-base" also. Before PR merge, it produced the commit where the feature branch started as desired. After PR merge, it produced the commit where the merge occurred, which is not what I want.

#7089
I cannot even checkout 177092a now. Can we find any test cases in https://github.com/go-gitea/gitea/pulls ? git checkout 160e7ed worked at the current HEAD of the master branch. Am I missing anything?

git checkout 177092aa4b40457654123d13ebcf921843b7a877
fatal: reference is not a tree: 177092aa4b40457654123d13ebcf921843b7a877

git log $(git merge-base master branch-name)..branch-name
This behavior also changes before and after PR merge.

Yes, it would change after a pr merge because the merge base would be the merge point at that point.

You would need to use the shas of the trees pre-merge to get the original merge-base but look at git's own documentation about merge-base.

Are there any REST API? Can I wget and parse the html of the PR webpage?

What are you trying to get exactly? Using Gitea feature branches as an example for looking at commits on branches is not necessarily the most sensible - we squash our commits into a single commit with the pr # in the commit line and once those features are squashed most developers will simply delete the branch losing that information.

Other projects may use a merge branch strategy which will keep the history at a cost of a potentially complicated tree. In those cases you should be able to interrogate the git history as described above. Or if you prefer graphically with gitk and I think there's a graphical representation available in Gitea.

In terms of APIs - apart from git I don't think there is one and in general I think we should avoid creating APIs to git - git is itself an API. I think however our PullRequest APIs should give you the git URL to pull/fetch the branch - and if they don't or it's not obvious then we should change that.

Our team practice git flow. I am handling pull requests, merging, and code review for about 40 developers. When a pull requests comes, I would like to list the changed files from a feature branch and review the code. I would like to exclude files changed on the feature branch as a result of catching up with (daily merging from) the develop branch.

https://try.gitea.io/api/swagger
I am going to try the APIs here.

Since I am also the admin, I can look at the sqlite file (gitea.db) for pull_request.merge_base. Is the merge_base hash frozen at the time of PR creation? I considering doing a set operation like

(git diff --name-only feature_head..merge_base) minus (git diff --name-only develop_head..merge_base)

How can I figure out the parent of pull_request.merged_commit_id? There should be 2 parents. One on the feature branch and another on the develop branch.

git rev-parse $merged_commit_id^1 gives only one result. Maybe I have to parse the output of git log for the line Merge: <develop_hash> <feature_hash>
