Git HowTo

Push until specific commit

This how you can push until a specific commit (hash):

COMMIT=1f72f3ba764e4ece0cd556779781b414c2efacb6
echo "Summary of the commits diff:"
git --no-pager log origin/main..$COMMIT --oneline
git push origin $COMMIT:main

Fork aktualisieren

In diesem Beispiel haben wir einen Fork:

Upstream: https://github.com/Mint-System/Odoo-Build/
Origin: https://github.com/sozialinfo/Odoo-Build

Einrichten

Repo öffnen.

cd Sozialinfo-Odoo-Build
git switch 16.0

Mit git remote -v im Repo die Remotes anzeigen. Wenn nötig den Upsream hinzufügen:

git remote add upstream git@github.com:Mint-System/Odoo-Build.git

Mit git switch Mint-System-16.0 den Upstream-Branch wechseln. Wenn nötig erstellen:

git switch --oprhan Mint-System-16.0

Von dort den Upstream-Branch pullen.

git pull upstream 16.0

Ausführen

Aktualisieren Upstream-Branch.

git switch Mint-System-16.0 
git pull upstream 16.0

Submodules-Datei auschecken.

git checkout 16.0 .gitmodules
git stash

In Main-Branch wechseln.

git switch 16.0
git rebase Mint-System-16.0
git stash pop

Submodule dem Index inzufügen.

task git-submodule-add git@github.com:sozialinfo/odoo-apps-sozialinfo.git addons/sozialinfo

Referenzen der Submodule aktualisieren.

task checkout 16.0
task git-submodule-pull

Alles committen.

Run rebase

Resolve rebase conflicts

Here is a common scenario when rebasing a branch from the main branch causes a conflict:

➜  sozialinfo git:(DEV-466-advert) ✗ git rebase 16.0
Auto-merging job_portal_exporter/static/description/index.html
CONFLICT (content): Merge conflict in job_portal_exporter/static/description/index.html
error: could not apply 6af8cb6... feat: init advert base module
hint: Resolve all conflicts manually, mark them as resolved with
hint: "git add/rm <conflicted_files>", then run "git rebase --continue".
hint: You can instead skip this commit: run "git rebase --skip".
hint: To abort and get back to the state before "git rebase", run "git rebase --abort".
Could not apply 6af8cb6... feat: init advert base module

In this case the commit 6af8cb6 could not be applied to the branch, because the file index.html has been update in both branches.

Running git diff gives us more details about the conflict. Git tries to combine the conflicted files and separates the conflicting lines with markers. A merge editor can help resolving the conflict:

After resolving the conflict you run git rebase --continue. You are prompted to confirm the commit. Git will update the commit with resolved file.

Next is a more complex conlfict.

Two conflicts could be resolved automatically. The file education_professional_event.py has a conflict that needs to be resolved.

We selected Accept Incoming Change which is the change you made in the branch. When trying to continue the rebase the following message might show up:

➜  sozialinfo git:(03c8a41) ✗ git rebase --continue
education_meilisearch/models/education_professional_event.py: needs merge
You must edit all merge conflicts and then
mark them as resolved using git add

When resolving conflicts you have to add the files git add .. You should be greeted by this message once the rebase has finished:

➜  sozialinfo git:(03c8a41) ✗ git rebase --continue
[detached HEAD 7ab738a] feat: use convert datetime from mixin
 4 files changed, 13 insertions(+), 62 deletions(-)
Successfully rebased and updated refs/heads/DEV-466-advert.

Make sure to push the changes with git push -f. After a rebase the local git history is different from the remote history.
