Updates VMID parameter and field types from int to uint64 throughout the Proxmox provider implementation,
including API request structures, provider structs, client methods, and LXC-related functions.
Also updates string conversion calls from strconv.Itoa to strconv.FormatUint.
This is a large-scale refactoring across the codebase that replaces the custom
`gperr.Error` type with Go's standard `error` interface. The changes include:
- Replacing `gperr.Error` return types with `error` in function signatures
- Using `errors.New()` and `fmt.Errorf()` instead of `gperr.New()` and `gperr.Errorf()`
- Using `%w` format verb for error wrapping instead of `.With()` method
- Replacing `gperr.Subject()` calls with `gperr.PrependSubject()`
- Converting error logging from `gperr.Log*()` functions to zerolog's `.Err().Msg()` pattern
- Update NewLogger to handle multiline error message
- Updating `goutils` submodule to latest commit
This refactoring aligns with Go idioms and removes the dependency on
custom error handling abstractions in favor of standard library patterns.
Add Validate() method to NodeConfig that implements the CustomValidator
interface. The method checks all services and files for invalid shell
metacharacters (&, $(), etc.) to prevent shell injection attacks.
Testing: Added validation_test.go with 6 table-driven test cases covering
valid inputs and various shell metacharacter injection attempts.
Add new `/proxmox/tail` API endpoint for streaming file contents from Proxmox
nodes and LXC containers via WebSocket. Extend journalctl endpoint to support
filtering by multiple services simultaneously.
Changes:
- Add `GET /proxmox/tail` endpoint supporting node-level and LXC container file tailing
- Change `service` parameter from string to array in journalctl endpoints
- Add input validation (`checkValidInput`) to prevent command injection
- Refactor command formatting with proper shell quoting
Security: All command inputs are validated for dangerous characters before
- Add BaseURL field to Client for node-level route configuration
- Change VMID from int to *int to support three states:
- nil: auto-discover node or VM from hostname/IP/alias
- 0: node-level route (direct to Proxmox node API)
- >0: LXC/QEMU resource route with container control
- Change Service string to Services []string for multi-service support
- Implement proper node-level route handling: HTTPS scheme,
hostname from node BaseURL, default port 8006
- Move initial UpdateResources call to Init before starting loop
- Move proxmox auto-discovery earlier in route validation
BREAKING: NodeConfig.VMID is now a pointer type; NodeConfig.Service
renamed to Services (backward compatible via alias)
This change enables Proxmox node-level operations without requiring a specific
LXC container VMID.
**Features added:**
- New `/proxmox/journalctl/{node}` API endpoint for streaming node journalctl
- Route configuration support for Proxmox nodes (VMID = 0)
- `ReverseLookupNode` function for node discovery by hostname/IP/alias
- `NodeJournalctl` method for executing journalctl on nodes
**Behavior changes:**
- VMID parameter in journalctl endpoints is now optional
- Routes targeting nodes (without specific containers) are now valid
**Bug fixes:**
- Fixed error message variable reference in route validation
The LXCCommand method contained duplicate websocket handling logic for connecting to Proxmox's VNC terminal proxy. This refactoring extracts the common websocket connection, streaming, and cleanup logic into a new NodeCommand method on the Node type, allowing LXCCommand to simply format the pct command and delegate.
The go-proxmox submodule was also updated to access the NewNode constructor, which provides a cleaner API for creating node instances with the HTTP client.
- Moves ~100 lines of websocket handling from lxc_command.go to node.go
- Adds reusable NodeCommand method for executing commands via VNC websocket
- LXCCommand now simply calls NodeCommand with formatted command
- Maintains identical behavior and output streaming semantics
- Add VMResource wrapper type with cached IP addresses for efficient lookups
- Implement concurrent IP fetching during resource updates (limited concurrency)
- Add ReverseLookupResource for discovering VMs by IP, hostname, or alias
- Prioritize interfaces API over config for IP retrieval (offline container fallback)
- Enable routes to auto-discover Proxmox resources when no explicit config provided
- Fix configuration type from value to pointer slice for correct proxmox client retrievel
- Ensure Proxmox providers are initialized before route validation
Implement a new API endpoint to retrieve real-time statistics for Proxmox
LXC containers, similar to `docker stats` functionality.
Changes:
- Add `GET /api/v1/proxmox/stats/:node/:vmid` endpoint with HTTP and WebSocket support
- Implement resource polling loop to cache VM metadata every 3 seconds
- Create `LXCStats()` method with streaming (websocket) and single-shot modes
- Format output as: STATUS|CPU%|MEM USAGE/LIMIT|MEM%|NET I/O|BLOCK I/O
- Add `GetResource()` method for efficient VM resource lookup by kind and ID
- Fix task creation bug using correct client reference

Centralize Proxmox node configuration by moving `ProxmoxConfig` from `internal/types/idlewatcher.go` to a new `NodeConfig` struct in `internal/proxmox/node.go`.
- Add `proxmox` field to route; allowing `proxy.app.proxmox` labels and corresponding route file config
- Added `service` optional field to NodeConfig for service identification
- Integrated Proxmox config directly into Route struct with proper validation
- Propagate Proxmox settings to Idlewatcher during route validation
- Updated swagger documentation to reflect schema changes
