Revamps the entire user deletion process to resolve critical performance bottlenecks that caused the web panel and database to freeze when removing multiple users.
- **Backend:** Core scripts (`kickuser.py`, `remove_user.py`) and the database layer are re-engineered to handle multiple users in a single, efficient batch operation using MongoDB's `delete_many`.
- **API:** A new `POST /api/v1/users/bulk-delete` endpoint is introduced for batch removals. The existing single-user `DELETE` endpoint is fixed to align with the new bulk logic.
- **Frontend:** The Users page now intelligently calls the bulk API when multiple users are selected, drastically improving UI responsiveness and reducing server load.
Refactored the web panel's user link generation to resolve a major performance bottleneck. Previously, fetching links for N users would trigger N separate script executions, causing significant delays from process startup overhead.
- Introduced a new bulk API endpoint (`/api/v1/users/uri/bulk`) that accepts a list of usernames and calls the backend script only once.
- Updated the frontend JavaScript in `users.html` to use this new endpoint, replacing N parallel API calls with a single one.
- Cleaned up the `wrapper_uri.py` script for better readability and maintainability.
Refactored the aiohttp authentication server to be a purely read-only service. Removed all file write operations from the authentication logic to eliminate disk I/O and reduce CPU overhead during connection attempts.
The responsibility for persistently blocking users by writing to `users.json` is now fully delegated to the external scheduler service, allowing the auth server to function as a faster, more efficient gatekeeper.
- Replace synchronous file operations with async aiofiles
- Implement concurrent data gathering using asyncio.gather()
- Move API calls to thread pool executor
- Add LRU cache for config file reads
- Optimize parsing functions for single-pass processing
- Reduce measurement intervals for faster response times
- Add system uptime and boot time display
- Track total network traffic since last reboot from /proc/net/dev
- Separate system traffic (since reboot) from user traffic (all-time)
- Add human-readable uptime formatting
- Enhance output with clear traffic categorization
Introduces a new 'unlimited_user' flag for users. When set to true, the user is exempt from the concurrent IP limit enforcement by `limit.sh`.
- `core/scripts/hysteria2/add_user.py`:
- Adds an optional `unlimited_user` argument (defaults to false).
- Stores the `unlimited_user` boolean in the `users.json` file when adding a user.
- `core/scripts/hysteria2/limit.sh`:
- Modifies `check_ip_limit` function to first check the `unlimited_user` flag for the connecting user in `users.json`.
- If the flag is true, the script bypasses the IP limit check for that user.
- Uses `jq` for reliable parsing and includes a `grep` fallback for systems without `jq`.
- Existing users without the flag are treated as limited (default behavior).
Introduces a dedicated system for managing a list of external nodes, each with a unique name and IP address. This feature is designed for multi-node deployments.
Refactored normalsub.py to use the user's password as the identifier in the subscription URL path instead of the username, enhancing privacy by making user enumeration harder.
