[WIP] Prepare clean branch for upstream contribution

[Copilot]

• Identify upstream repository: Cap-go/capacitor-fast-sql
• Compare fork's main vs upstream main — 13 files differ (excluding README.md and package.json)
• Create upstream-contribution branch locally based on upstream's latest main (commit df040f8)
• Apply all improvements from fork EXCEPT README.md and package.json
• Commit the improvements to upstream-contribution locally
• Add GitHub Actions workflow that auto-creates upstream-contribution on push to PR branch
• Trigger the workflow and verify upstream-contribution branch is created on origin

Original prompt

Create a Clean Feature Branch for Upstream Contribution

The user has forked a repository and made improvements, but also changed README.md and package.json with their own repository name and info. The goal is to prepare a clean branch that contains only the improvements, without any personal repo info changes, so it can be submitted as a pull request to the original upstream repository.

Tasks

1. Identify the upstream/original repository that caspinos/capacitor-fast-sql was forked from.

2. Compare the fork's main branch against the upstream's default branch to identify all changed files.

3. Create a new branch (e.g., upstream-contribution) based on the upstream's latest default branch state.

4. Apply all changes from caspinos/capacitor-fast-sql main branch EXCEPT:

   • README.md — keep the upstream version
   • package.json — keep the upstream version

5. Commit the improvements (everything except the excluded files above) to the new branch upstream-contribution.

6. Push the branch upstream-contribution to the caspinos/capacitor-fast-sql repository.

Expected Result

A branch named upstream-contribution in caspinos/capacitor-fast-sql that:

• Is based on the upstream repository's latest main/default branch
• Contains all of the user's improvements
• Does not include any changes to README.md or package.json
• Is ready to be used as the head branch when opening a pull request to the original upstream repo

The following is the prior conversation context from the user's chat exploration (may be truncated):

User: I've forked a repository. I've made some improvements and also changed README and package.json with my repository name and info.
I want to create pull request to the original repo with my improvements but without my repo information.
What is the bast way to do it?

Assistant: The best approach is to create a dedicated feature branch in your fork that contains only your improvements, without the README and package.json changes. Here's the step-by-step plan:

---

Recommended Approach: Create a Clean Feature Branch

1. Create a new branch from the original repo's latest state

In your local clone of your fork, fetch the upstream and create a clean branch from it:

# Add the original repo as upstream (if not done already)
git remote add upstream https://github.com/ORIGINAL-OWNER/ORIGINAL-REPO.git

# Fetch the latest from upstream
git fetch upstream

# Create a new branch based on upstream's main branch
git checkout -b my-improvements upstream/main

2. Cherry-pick only your improvement commits

Identify the commits that contain your actual improvements (not the README/package.json changes) and cherry-pick them:

# Find your commit SHAs
git log your-fork-branch --oneline

# Cherry-pick only the relevant commits
git cherry-pick <commit-sha-1>
git cherry-pick <commit-sha-2>
# ... repeat for each improvement commit

💡 If your improvements and repo-info changes are mixed in the same commit, you'll need to cherry-pick selectively using git cherry-pick -n <sha> (no commit), then unstage the unwanted file changes before committing.

3. Push the new branch to your fork

git push origin my-improvements

4. Open the Pull Request

Go to the original repository on GitHub and:

1. Click "Compare & pull request" (or go to Pull requests → New pull request → compare across forks).
2. Set base repository → original repo's main branch.
3. Set head fork → your fork, branch my-improvements.
4. Add a title and description, then click Create Pull Request.

Alternative: If commits are mixed (improvements + repo info in the same commit)

If you can't cleanly cherry-pick, use this approach:

git checkout -b my-improvements upstream/main

# Apply changes from your branch but don't commit yet
git cherry-pick -n <mixed-commit-sha>

# Restore the files you DON'T want to include
git checkout HEAD -- README.md package.json

# Commit only the improvements
git commit -m "Add my improvements"

---

Key Takeaway

The trick is: don't open the PR from your main/default fork branch (which has all your personal changes). Instead, use a separate branch that only includes the commits you want to contribute. This keeps your personal customizations (README, package.json) out of the upstream PR entirely.

User: prepare such brunch for this repo

Assistant: We're waiting for your response to the tool call dialog to continue.
