Hello, maybe it's a bug in later GIT versions (2.36.1 here) but I kind of struggle to get git-subtree to work properly. I even recreated the repo, I use for the subtree, from scratch to get sure there are no backreferences to the repo I've added the subtree to. This is the repo, I want to have as "subtree" in other repos: https://github.com/M-Reimer/webext-utils I now pulled this into two projects as subtree using the command https://github.com/M-Reimer/undoclosetab https://github.com/M-Reimer/savescreenshot For both projects I used the command: git subtree add --prefix utils git@xxxxxxxxxx:M-Reimer/webext-utils.git master In the first project (undoclosetab) I then added a new commit ("Add managed preference support") and pushed this back to the "subtree repo" using: git subtree push --prefix utils git@xxxxxxxxxx:M-Reimer/webext-utils.git master If I now try to pull this into my second project (savescreenshot), then git creates a merge commit for no reason. git subtree pull --prefix utils "git@xxxxxxxxxx:M-Reimer/webext-utils.git" master remote: Enumerating objects: 5, done. remote: Counting objects: 100% (5/5), done. remote: Compressing objects: 100% (2/2), done. Unpacking objects: 100% (3/3), 1.94 KiB | 497.00 KiB/s, done. remote: Total 3 (delta 1), reused 3 (delta 1), pack-reused 0 >From github.com:M-Reimer/webext-utils * branch master -> FETCH_HEAD Merge made by the 'ort' strategy. utils/storage.js | 57 +++++++++++++++++++++++++++++++++++++++++++++++++++++++- 1 file changed, 56 insertions(+), 1 deletion(-) Why does this happen? As soon as I have this merge commit a following "subtree push" also pushes this merge commit to the subtree repo and also pushes tags that are not relevant there. I'm out of ideas now. What I want to do: I want to be able to develop on modules, I have in the "subtree repo" in every project I want and then push the changes to the subtree repo for pulling into the other projects. That's why I don't want to use "squash" as I don't want to do development only in the subtree repo directly. Thanks for any hints. Manuel
