[Question] Is it possible to see merged commits in a single merge ?

[mxrch]

Hi !
Is there a way to see merged commits by a merge ?
For example, this "Merge pull request" commit : jofpin/trape@6baae24
By looking at the pull request reference (https://github.com/jofpin/trape/pull/313/commits), we can see it has merged 3 commits : 98bae53, b17c6c1 and 626bca6.

In GitPython, by having the commit object 6baae24 (the merge), I can get the first merged commit (626bca6) by looking at the commit parents, but not the two others (logical, it's how Git works).
But using the git log command, I can extract them in raw :

(Pdb) repo.git.log("6baae24^..6baae24")
"commit 6baae245691997742a51979767254d7da580eadd\nMerge: e362980 626bca6\nAuthor: Jose Pino <[email protected]>\nDate:   Sun Jun 20 11:33:43 2021 -0500\n\n    Merge pull request #313 from captain-woof/typos_and_error_fixes\n    \n    Typos and error fixes\n\ncommit 626bca666b427998b2a5cf8753737425614c8a40\nAuthor: Captain Woof <[email protected]>\nDate:   Fri May 21 09:33:45 2021 +0530\n\n    Fixed the issue where user_objects module wasn't imported\n\ncommit b17c6c133e6a5a7049d28ca88faf267eb466fe65\nAuthor: Captain Woof <[email protected]>\nDate:   Fri May 21 08:59:36 2021 +0530\n\n    Fixed the 'unexpected keyword: version' issue\n\ncommit 98bae532d213b9692322fafdda1d4f9c19093bc5\nAuthor: Captain Woof <[email protected]>\nDate:   Fri May 21 08:22:38 2021 +0530\n\n    Changed 'python2' to 'python3' and os module import"

I can use a regex to parse them, but I would know if there is a more pythonic way implemented in GitPython to do this !
I didn't see ways for this in the documentation and the implemented methods. If there isn't actually a way to do this, why not adding it ?

Thank you in advance 😄

Temporary solution to extract hexsha of merged commits :

for commit in repo.iter_commits():
    if len(commit.parents) > 1:
        merged_commits = re.findall(r'\S{40}', repo.git.log(f"{commit.hexsha}^..{commit.hexsha}"))[1:]

There are no specialized facilities to support graph analysis in GitPython, so using repo.git.log(…) is the best and fastest way of doing this at the moment.
