 # MyFSIO
 
-MyFSIO is an S3-compatible object storage server with a Rust runtime and a filesystem-backed storage engine. The active server lives under `rust/myfsio-engine` and serves both the S3 API and the built-in web UI from a single process.
+A lightweight, S3-compatible object storage system built with Flask. MyFSIO implements core AWS S3 REST API operations with filesystem-backed storage, making it ideal for local development, testing, and self-hosted storage scenarios.
-
-The `python/` implementation is deprecated as of 2026-04-21. It remains in the repository for migration reference and legacy tests, but new development and supported runtime usage should target the Rust server.
 
 ## Features
 
-- S3-compatible REST API with Signature Version 4 authentication
+**Core Storage**
-- Browser UI for buckets, objects, IAM users, policies, replication, metrics, and site administration
+- S3-compatible REST API with AWS Signature Version 4 authentication
-- Filesystem-backed storage rooted at `data/`
+- Bucket and object CRUD operations
-- Bucket versioning, multipart uploads, presigned URLs, CORS, object and bucket tagging
+- Object versioning with version history
-- Server-side encryption and built-in KMS support
+- Multipart uploads for large files
-- Optional background services for lifecycle, garbage collection, integrity scanning, operation metrics, and system metrics history
+- Presigned URLs (1 second to 7 days validity)
-- Replication, site sync, and static website hosting support
 
-## Runtime Model
+**Security & Access Control**
+- IAM users with access key management and rotation
+- Bucket policies (AWS Policy Version 2012-10-17)
+- Server-side encryption (SSE-S3 and SSE-KMS)
+- Built-in Key Management Service (KMS)
+- Rate limiting per endpoint
 
-MyFSIO now runs as one Rust process:
+**Advanced Features**
+- Cross-bucket replication to remote S3-compatible endpoints
+- Hot-reload for bucket policies (no restart required)
+- CORS configuration per bucket
 
-- API listener on `HOST` + `PORT` (default `127.0.0.1:5000`)
+**Management UI**
-- UI listener on `HOST` + `UI_PORT` (default `127.0.0.1:5100`)
+- Web console for bucket and object management
-- Shared state for storage, IAM, policies, sessions, metrics, and background workers
+- IAM dashboard for user administration
+- Inline JSON policy editor with presets
+- Object browser with folder navigation and bulk operations
+- Dark mode support
 
-If you want API-only mode, set `UI_ENABLED=false`. There is no separate "UI-only" runtime anymore.
+## Architecture

 ## Quick Start
 
-From the repository root:
-
 ```bash
-cd rust/myfsio-engine
+# Clone and setup
-cargo run -p myfsio-server --
+git clone https://gitea.jzwsite.com/kqjy/MyFSIO
+cd s3
+python -m venv .venv
+
+# Activate virtual environment
+# Windows PowerShell:
+.\.venv\Scripts\Activate.ps1
+# Windows CMD:
+.venv\Scripts\activate.bat
+# Linux/macOS:
+source .venv/bin/activate
+
+# Install dependencies
+pip install -r requirements.txt
+
+# Start both servers
+python run.py
+
+# Or start individually
+python run.py --mode api   # API only (port 5000)
+python run.py --mode ui    # UI only (port 5100)
 ```
 
-Useful URLs:
+**Credentials:** Generated automatically on first run and printed to the console. If missed, check the IAM config file at `<STORAGE_ROOT>/.myfsio.sys/config/iam.json`.
 
-- UI: `http://127.0.0.1:5100/ui`
+- **Web Console:** http://127.0.0.1:5100/ui
-- API: `http://127.0.0.1:5000/`
+- **API Endpoint:** http://127.0.0.1:5000
-- Health: `http://127.0.0.1:5000/myfsio/health`
-
-On first boot, MyFSIO creates `data/.myfsio.sys/config/iam.json` and prints the generated admin access key and secret key to the console.
-
-### Common CLI commands
-
-```bash
-# Show resolved configuration
-cargo run -p myfsio-server -- --show-config
-
-# Validate configuration and exit non-zero on critical issues
-cargo run -p myfsio-server -- --check-config
-
-# Reset admin credentials
-cargo run -p myfsio-server -- --reset-cred
-
-# API only
-UI_ENABLED=false cargo run -p myfsio-server --
-```
-
-## Building a Binary
-
-```bash
-cd rust/myfsio-engine
-cargo build --release -p myfsio-server
-```
-
-Binary locations:
-
-- Linux/macOS: `rust/myfsio-engine/target/release/myfsio-server`
-- Windows: `rust/myfsio-engine/target/release/myfsio-server.exe`
-
-Run the built binary directly:
-
-```bash
-./target/release/myfsio-server
-```

+
+## IAM & Access Control
+
+### Users and Access Keys
+
+On first run, MyFSIO creates a default admin user (`localadmin`/`localadmin`). Use the IAM dashboard to:
+
+- Create and delete users
+- Generate and rotate access keys
+- Attach inline policies to users
+- Control IAM management permissions
+
+### Bucket Policies
+
+Bucket policies follow AWS policy grammar (Version `2012-10-17`) with support for:
+
+- Principal-based access (`*` for anonymous, specific users)
+- Action-based permissions (`s3:GetObject`, `s3:PutObject`, etc.)
+- Resource patterns (`arn:aws:s3:::bucket/*`)
+- Condition keys
+
+**Policy Presets:**
+- **Public:** Grants anonymous read access (`s3:GetObject`, `s3:ListBucket`)
+- **Private:** Removes bucket policy (IAM-only access)
+- **Custom:** Manual policy editing with draft preservation
+
+Policies hot-reload when the JSON file changes.
+
+## Server-Side Encryption
+
+MyFSIO supports two encryption modes:
+
+- **SSE-S3:** Server-managed keys with automatic key rotation
+- **SSE-KMS:** Customer-managed keys via built-in KMS
+
+Enable encryption with:
+```bash
+ENCRYPTION_ENABLED=true python run.py
+```
+
+## Cross-Bucket Replication
+
+Replicate objects to remote S3-compatible endpoints:
+
+1. Configure remote connections in the UI
+2. Create replication rules specifying source/destination
+3. Objects are automatically replicated on upload
 
 ## Docker
 
-Build the Rust image from the `rust/` directory:
-
 ```bash
-docker build -t myfsio ./rust
+docker build -t myfsio .
-docker run --rm -p 5000:5000 -p 5100:5100 -v "${PWD}/data:/app/data" myfsio
+docker run -p 5000:5000 -p 5100:5100 -v ./data:/app/data myfsio
 ```
 
-If the instance sits behind a reverse proxy, set `API_BASE_URL` to the public S3 endpoint.
-
-## Linux Installation
-
-The repository includes `scripts/install.sh` for systemd-style Linux installs. Build the Rust binary first, then pass it to the installer:
-
-```bash
-cd rust/myfsio-engine
-cargo build --release -p myfsio-server
-
-cd ../..
-sudo ./scripts/install.sh --binary ./rust/myfsio-engine/target/release/myfsio-server
-```
-
-The installer copies the binary into `/opt/myfsio/myfsio`, writes `/opt/myfsio/myfsio.env`, and can register a `myfsio.service` unit.
-
 ## Testing
 
-Run the Rust test suite from the workspace:
-
 ```bash
-cd rust/myfsio-engine
+# Run all tests
-cargo test
+pytest tests/ -v
+
+# Run specific test file
+pytest tests/test_api.py -v
+
+# Run with coverage
+pytest tests/ --cov=app --cov-report=html
 ```
 
-## Health Check

-# Deprecated Python Implementation
-
-The Python implementation of MyFSIO is deprecated as of 2026-04-21.
-
-The supported server runtime now lives in `../rust/myfsio-engine` and serves the S3 API and web UI from the Rust `myfsio-server` binary. Keep this tree for migration reference, compatibility checks, and legacy tests only.
-
-For normal development and operations, run:
-
-```bash
-cd ../rust/myfsio-engine
-cargo run -p myfsio-server --
-```
-
-Do not add new product features to the Python implementation unless they are needed to unblock a migration or compare behavior with the Rust server.
