- Narrow IOU lock scope to only cover application_id allocation,
allowing concurrent IOU node creation via Pool(concurrency=5)
- Parallelize link creation during project.open() using Pool(concurrency=5)
instead of sequential processing
- Add batch UDP port allocation endpoint on compute to allocate N ports
in a single HTTP call
- Pre-allocate UDP ports per compute before link creation during project
loading, reducing HTTP round-trips
- UDPLink.create() falls back to individual port allocation if no
pre-allocated port is available
Both is_safe_path rejection and PermissionError were returning 403
without a detail message, making them indistinguishable in logs.
Add specific detail strings to each:
- is_safe_path: 'Path is outside the project directory'
- PermissionError (write): 'Permission denied writing to ...'
- PermissionError (delete): 'Permission denied deleting ...'
The inner try-except caught OSError/UnicodeEncodeError with 'pass',
silently swallowing all write failures and returning HTTP 204 as if
the file was written successfully.
Remove the nested try-except and let errors propagate properly:
- OSError → 500 with error detail
- PermissionError → 403 (already handled)
- FileNotFoundError → 404 (already handled)
- Stream file GET/POST through controller without buffering in memory
- Add recursive and subdirectory filtering to node file listing
- Replace file extension with magic-based file type detection
- Add DELETE endpoint for node and project files
- Include directories in listing response
- Add params and stream support to http_query
- Fix lambda closures, streamer exception scope, and delete error codes
When a Docker node is deleted, the compute node's DELETE endpoint only calls
node.delete() which removes the working directory but does not remove the node
object from the project's self._nodes collection. This causes ghost nodes to
remain in memory.
When project variables are updated, the code iterates through ALL nodes in
memory and calls update() on them. For ghost nodes with VNC configuration, this
triggers VNC startup attempts, resulting in 60-second timeouts waiting for X11
socket files that don't exist.
The fix adds await node.project.remove_node(node) to ensure the node object is
removed from the project's node collection when deleted, matching the behavior
of other node types that use manager.delete_node() which already calls
project.remove_node().
This resolves the issue where updating project variables after deleting a VNC
Docker container would timeout with: 'x11 socket file "/tmp/.X11-unix/X100"
does not exist'
Fixes issue #2755
Enhance the node files API to include comprehensive file metadata:
- File size in bytes
- File creation time (ISO 8601 format)
- File modification time (ISO 8601 format)
- File extension
Create new NodeFile schema to support these additional fields
while keeping the existing ProjectFile schema for backward compatibility.
This provides users with better information to manage and identify
files in the Web UI.

Implement issue #2719 - Add API endpoint to list project files
- Add GET /v3/projects/{project_id}/nodes/{node_id}/files endpoint
- Add list_node_files() method to Project class
- Add security checks to prevent path traversal
- Filter out .ghost temporary files
- Return file paths with MD5 checksums
- Require Node.Audit privilege
This allows users to discover dynamically created files
such as QEMU disk images created via the disk image API.

* fix(deps): upgrade swagger-ui to 4.1.3 to fix CVE-2018-25031
CVE-2018-25031: swagger-ui < 4.1.3 has a spoofing vulnerability
where remote attackers can display remote OpenAPI definitions
via crafted URLs.
- swagger-ui: 3.30.0 → 4.1.3

* fix(api): change FastAPI version from "v3" to "3.0.0" for Swagger UI 4.1.3 compatibility
Swagger UI 4.x enforces stricter version format validation.
The version "v3" is not accepted by the new validator.
Changed from:
- version="v3"
To:
- version="3.0.0"
This affects both controller and compute API definitions.

* fix(deps): upgrade swagger-ui to 5.32.4
Fixes "Unable to render this definition" error when loading OpenAPI 3.0
docs. Swagger UI 3.x had incomplete OpenAPI 3.0 support.
- swagger-ui: 3.19.1 → 5.32.4 (latest)

Remove all SPICE WebSocket-related code due to frontend dependency issues
with spice-html5 library (missing RSAKey/BigInteger implementations).
Changes:
- Remove start_spice_websocket_console() from BaseNode
- Remove SPICE WebSocket endpoints from QEMU and Docker compute APIs
- Remove SPICE WebSocket proxy endpoint from controller API
- Remove WebSocket subprotocol handling from authentication layers
- Remove SPICE documentation
The SPICE console type remains functional for direct connections,
but WebSocket proxy support has been removed.

Add WebSocket-based console support for SPICE protocol, enabling
browser-based graphical console access with enhanced features
like clipboard sharing, USB redirection, and audio streaming.
Changes:
- Add start_spice_websocket_console() method in BaseNode for SPICE
WebSocket to TCP bridging with bidirectional binary forwarding
- Add /console/spice WebSocket endpoints in QEMU and Docker compute APIs
- Add /console/spice WebSocket proxy endpoint in controller API
- Add comprehensive API documentation in docs/features/
Supported console types:
- spice: Basic SPICE protocol support
- spice+agent: SPICE with spice-vdagent for enhanced features
Architecture:
- Browser WebSocket → Controller (JWT + RBAC) → Compute (Basic Auth)
- No external websockify processes required
- Consistent with existing VNC WebSocket implementation
Add VNC console WebSocket endpoints for Docker and QEMU nodes:
- Add /console/vnc WebSocket endpoint to compute API (Docker & QEMU)
- Add /console/vnc WebSocket endpoint to controller API
- Implement start_vnc_websocket_console() in BaseNode
- Forward VNC WebSocket traffic between controller and compute layers
The implementation provides bidirectional WebSocket to TCP forwarding
for VNC protocol (RFB) connections, allowing browser-based VNC console
access to containers and VMs.

Fixed IOU node suspend API to return proper HTTP 405 Method Not Allowed
error instead of misleading 204 No Content response.
Changes:
- Added HTTPException import to iou_nodes.py
- Fixed suspend_iou_node route from /stop to /suspend (bug fix)
- Changed response from 204 No Content to 405 Method Not Allowed
- Added clear error message: "Suspend is not supported for IOU nodes"
This fix ensures clients receive explicit feedback when attempting to
suspend IOU nodes, which do not support suspend functionality.
Related issue: IOU nodes previously returned 404 when suspend was called
due to incorrect route registration.
