You fix git rebase duplicate commits by resetting your branch to the remote state. Then you replay only your new local changes on top of that branch. Teams often face this issue when developers rewrite shared history and merge old branches. Broad branch permissions make this worse by letting anyone push rewritten commits to main.
Why git rebase duplicate commits happen and how to fix them
Rebasing does not move existing commits from one place to another. Instead, the version control system reads your changes and writes brand new commits. Each new commit gets a fresh hash ID based on its new parent commit. The old commits still exist in the history of anyone who pulled them earlier.
Duplicates appear when a developer rebases a branch that already exists on the remote server. When they pull again without rebasing, the system merges the old and new histories. Both sets of commits have the same text changes, Commit messages match too. Because their hash IDs differ, the system treats them as separate work.
To clean this up, you must align your local branch with the remote branch. First, save any uncommitted work in a safe temporary spot. Next, fetch the latest remote history and point your local branch to that exact point. You can also run an interactive rebase to drop the repeated entries by hand.
Preventing duplicate history in team workflows
Clear team rules stop duplicate commits before they enter your main codebase. Your golden rule should be to never rebase a public branch shared with others. Developers should only rebase feature branches that they work on alone. Once a branch has multiple authors, standard merges are much safer to use.
When a developer must update a rebased feature branch, a standard push will fail. The server rejects the push because the new history does not match the old one. At this point, many developers pull the remote branch and create a messy merge. Instead, they should use a safe force push that checks remote status first.
Repo hosts also offer branch rules that require linear history on main branches. You can set pull requests to squash all changes into one single commit. This removes any duplicate entries that accumulated inside the feature branch during review. Every feature then lands on the main branch as one clean record.

What native branch rules solve and what they miss
Native repo permissions control who can push or merge code into protected branches. You can block force pushes on main and require peer reviews before merging. These settings stop accidental history rewrites on your most important shared code branches. They also help teams keep a clean log of approved code changes.
Still, static repo roles only check who logs in to push code. They do not inspect what happens when those changes trigger automated jobs or database updates. A broken history can cause deployment tools to run the same migration script twice. Native git permissions cannot inspect live commands or redact emails and card numbers in results.
Once a developer or build server gets broad role access, every command runs unchecked. You need runtime controls to inspect individual statements and protect live data systems.
Govern statements and responses across databases and APIs
Good config and scoped roles are needed setup. They do not check single queries in flight or mask sensitive fields in returned rows. Across Postgres, MySQL, SQL Server, MongoDB, ClickHouse, Kubernetes APIs, SSH, and internal HTTP endpoints, hoop.dev runs beside each supported service as an open-source proxy, a sidecar for your database or API.
First, hoop.dev guardrails block banned queries before they run. Then hoop.dev data masking rewrites matched sensitive values in responses in memory. The audit trail records every statement and verdict per resource. Furthermore, hoop.dev holds SOC 2 Type II and is open source on GitHub.
Frequently asked questions
Why do I see the same commit twice after a pull?
You rebased commits that were already pushed to the remote server earlier. Pulling merged those old remote commits with your newly rewritten local commits.
How do I remove duplicate commits from my local branch?
Start an interactive rebase covering the range of your recent branch history. Delete the lines for the duplicate commits, or reset hard to the remote branch.
Should I merge or rebase when working with other developers?
Always use merge when multiple developers push to the exact same branch. Save rebase for cleaning up your own private local commits before opening a review.
