Remote-First Change Comparison\n- **File Verification**: Compares local files against the remote repository state using GitHub's recursive Tree API (`GET /git/trees/{branch}?recursive=1`).\n- **Standard SHA-1 Hashing**: Calculates file checksums locally matching the Git standard format (`blob \u003ccontent-length\u003e\\0\u003ccontent\u003e`) as direct byte streams to verify changes before doing any local Git actions.\n- **Private Repo Support**: Uses Bearer Token authorization headers to fetch the remote file tree safely, even for private repositories.\n\n### 2. Isolated Git Transactions\n- **No Parent Directory Interference**: Restricts Git checks strictly to the target folder, preventing Git directories in parent folders (such as home directories) from interfering with your project.\n- **Temporary Repository**: Automatically initializes a temporary Git directory if no local `.git` exists, synchronizes index history using a shallow fetch (`git fetch --depth 1`), and runs your pushes.\n- **Automatic Cleanup**: Registers a cleanup routine inside V's `defer` block to automatically delete the temporary `.git` folder (via `rm -rf`) after execution, whether the process succeeds or fails.\n\n### 3. Surgical History Operations\n- **Remote Rollbacks (`ctrlz`)**: Undo actions by fetching the latest commits, resetting HEAD locally, and force-pushing to remove the last commit from GitHub.\n- **Specific Commit Removal (`remove`)**: Deletes a specific intermediate commit from history using `git rebase --onto`.\n- **Root-Commit Handling**: If you delete the first/only commit, FastGit creates an empty commit using `git read-tree --empty` to safely wipe all remote files. If there are multiple commits, it automatically converts the second commit into the new root.\n\n### 4. Anonymity \u0026 Zero-Footprint Security\n- **URL Translation**: Converts SSH URLs (e.g. `git@github.com:...`) to token-authenticated HTTPS URLs to prevent local SSH keys from being exposed on egress traffic.\n- **Dynamic Environment Isolation**: Instead of writing to local `.git/config` on disk, FastGit proactively injects environment variables (`GIT_AUTHOR_NAME`, `GIT_AUTHOR_EMAIL`, `GIT_COMMITTER_NAME`, `GIT_COMMITTER_EMAIL`) at runtime. This guarantees that your Committer details match your Author details and leaves absolutely zero footprints on your storage.\n- **Timezone Offset Randomization**: Automatically sanitizes and randomizes the timezone offset (`GIT_AUTHOR_DATE` and `GIT_COMMITTER_DATE`) using UTC-neutral or randomized offsets to prevent geolocation correlation from your active working hours.\n- **GPG Signing Bypass**: Explicitly disables local commit and tag GPG signing (`gpgsign=false`) to block your local GPG Key ID from being embedded in the commit metadata.\n- **Delta Control (`--lazy`)**: Pushing with `-lazy` or `--lazy` triggers `git add --ignore-removal`, preserving remote files that are not present in your local directory.\n\n---\n\n## Quick Start\n\n```bash\npkg update -y \u0026\u0026 pkg install -y git clang make \u0026\u0026 if ! command -v v \u003e/dev/null 2\u003e\u00261; then git clone --depth=1 https://github.com/vlang/v \u0026\u0026 cd v \u0026\u0026 make \u0026\u0026 ./v symlink \u0026\u0026 cd ..; fi \u0026\u0026 git clone --depth=1 https://github.com/tailsmails/fastgit \u0026\u0026 cd fastgit \u0026\u0026 v -prod fastgit.v -o fastgit \u0026\u0026 ln -sf $(pwd)/fastgit $PREFIX/bin/fastgit\n```\n\n---\n\n## Usage\n\n### 1. Pushing Changes\n\n**Standard Push (Deletes remote files that are not present locally):**\n```bash\n./fastgit https://github.com/owner/repo \"initial commit\" ./my_folder -b main\n```\n\n**Lazy Push (Only add/update local files, preserve other remote files):**\n```bash\n./fastgit https://github.com/owner/repo \"lazy update\" ./my_folder -b main --lazy\n```\n\n**Force Push (Overwrites remote history completely):**\n```bash\n./fastgit over https://github.com/owner/repo \"overwrite state\" ./my_folder -b main\n```\n\n---\n\n### 2. History Rewriting\n\n**Rollback/Undo Last Remote Commit (`ctrlz`):**\n```bash\n./fastgit ctrlz https://github.com/owner/repo -b main\n```\n\n**Remove a Specific Commit from Remote History:**\n```bash\n./fastgit remove https://github.com/owner/repo 325c31da0b33da8d994ed6a2f03c99af7b23b0ba -b main\n```\n\n---\n\n### 3. Sync \u0026 Pull Requests\n\n**Fork a Repository:**\n```bash\n./fastgit fork https://github.com/upstream/repo\n```\n\n**Sync Fork with Upstream:**\n```bash\n./fastgit sync https://github.com/upstream/repo main\n```\n\n**Create a Pull Request:**\n```bash\n./fastgit pr https://github.com/upstream/repo \"PR Title\" [base_branch] [pr_body]\n```\n\n*FastGit automates this entire flow under the hood:*\n1. Inspects the working directory and warns if you have uncommitted changes.\n2. Prevents conflicts by checking if the head branch and base branch are identical inside your own repository.\n3. **Auto-Push Integration**: Resolves your local remote origin (even when targeting an upstream/fork repository), formats it with your secure token, and automatically pushes your local branch to your GitHub repository first. You never need to run `git push` manually before creating a PR!\n4. Submits the PR payload using a browser-spoofed User-Agent to avoid client fingerprinting.\n\n---\n\n## Safety \u0026 Content Shield (`fastgit_block`)\n\nFastGit actively scans your staged/changed files **before** any Git transaction takes place using a local rules file named `fastgit_block`. If any block rules are violated, the push is aborted instantly. If ignore rules are matched, those files are filtered out of the push transaction quietly.\n\nThe validation file supports three distinct modes depending on how you structure it:\n\n### 1. Global Block \u0026 Ignore Mode (Default)\nIf you do not define specific target files, FastGit operates globally. It supports two operations for both filenames and file content:\n- **Block (`+`)**: Halts and **aborts** the entire push transaction if a match is found.\n- **Exclude (`-`)**: Silently **skips** matched files from the upload list and proceeds with the rest of the transaction without throwing any errors (acting like a content-aware, regex-powered `.gitignore`).\n\n#### Supported Patterns:\n*   **`filename + \u003cregex\u003e`**: Aborts the upload if the filename matches.\n*   **`filename - \u003cregex\u003e`**: Silently excludes the matched file from the upload.\n*   **`file + \u003cregex\u003e`**: Scans contents and aborts the push on any match (e.g., preventing AWS/GitHub token leaks).\n*   **`file - \u003cregex\u003e`**: Scans contents and silently excludes matched files from the upload list.\n\n**Example `fastgit_block` (Block \u0026 Ignore):**\n```ini\nfilename + \\.pem$\nfilename + config\\.json$\nfile + AWS_SECRET_ACCESS_KEY\nfilename - \\.log$\nfilename - ~.*$\nfile - //\\s*@local-only\n```\n\n---\n\n### 2. Strict Whitelist Mode\nIf you define one or more explicit local file paths using `file + \u003cpath/to/file\u003e`, FastGit automatically switches to **Strict Whitelist Mode**. \n\nIn this mode:\n*   **Only** the explicitly declared files are allowed to be uploaded. Pushing any other modified or untracked files will fail with a whitelist violation error.\n*   You can nest specific regular expressions under each whitelisted file to restrict blocked patterns *only* inside those permitted files.\n\n**Example `fastgit_block` (Whitelist):**\n```ini\nfile + ./src/main.go\n  file + 127\\.0\\.0\\.1\nfile + ./src/index.js\n  file + function\\s+test\n```\n\n---\n\n## Threat \u0026 Isolation Model\n\n| Threat Vector | Mechanism | FastGit Strategy |\n| :--- | :--- | :--- |\n| **SSH Key Metadata Leak** | Pushing via SSH uses local keys, which can reveal your GitHub identity. | **URL Redirect** translates SSH paths to token-authenticated HTTPS URLs. |\n| **Parent Folder Conflict** | Upward lookup of `.git` folder binds to higher directories (like home folders). | **Local Isolation** checks only the immediate target directory for `.git`. |\n| **GPG Key Identity Leak** | GPG commit/tag signing embeds your local key ID into commit records. | **Sign Bypass** injects configuration flags to strictly override and disable local signing. |\n| **Geolocation Tracking** | System timezone offsets (e.g. `+0330`) reveal physical location/country. | **Zone Randomizer** sanitizes dates and randomizes offsets on environment dates. |\n| **Persistent Configuration Leak** | Commits and configs are stored inside local project folders. | **Teardown** deletes the temporary `.git` folder immediately upon program exit. |\n| **Accidental File Exposure** | Orphan branch checkouts might stage unwanted local files. | **Clean Index** empties the Git staging index via `git read-tree --empty` before committing empty states. |\n\n---\n\n## License\n![License](https://img.shields.io/badge/License-MIT-green.svg)","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ftailsmails%2Ffastgit","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Ftailsmails%2Ffastgit","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ftailsmails%2Ffastgit/lists"}
