- Add class-level caches for loader and default RAM/NVRAM values
- When multiple IOU nodes use the same image, only the first one runs
the ld-linux --verify and iou-image -h subprocesses
- Subsequent nodes reuse cached results, saving ~2 subprocess calls per node
- Cache is populated only on successful subprocess execution to avoid
overwriting explicitly set ram/nvram values with stale cached defaults
Rootful Docker recreates volume mount points as root on start,
preventing the GNS3 process from writing files into node directories
while the container is running. self._fix_permissions() would resolve
this but is currently only called at container stop time.
- _fix_permissions: capture stderr, check returncode, only set
_permissions_fixed on success instead of silently marking as fixed
- list_node_files: wrap os.scandir in try-except to handle
PermissionError gracefully
- 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
Performance improvement for project variable updates when multiple containers
are present. Previously, nodes were updated serially in a for loop, causing:
- 5 containers: ~35 seconds (7s per container)
- 10 containers: ~70 seconds
- 20 containers: ~140 seconds (2min 20sec)
Changed to parallel processing using asyncio.gather(), reducing total time
to the duration of the slowest single node update (~7 seconds regardless
of container count).
The change maintains error handling with return_exceptions=True to ensure
one node's update failure doesn't prevent others from completing.
This is particularly important for users with large topologies containing
many Docker containers that need to be recreated when project variables change.
Related to issue #2755 ghost node timeout fix.
When updating project variables while Docker containers are running, the
system now properly handles both dictionary-format variables and Pydantic
Variable objects. This prevents AttributeError when containers are recreated
after variable updates.
Changes:
- Modified DockerVM.create() to detect and handle Pydantic Variable objects
- Updated _format_env() method to support both variable formats
- Maintains backward compatibility with existing dictionary format
Fixes error: AttributeError: 'Variable' object has no attribute 'get'
Fix F821 undefined name 'status' error by importing the status
module from fastapi. This resolves build errors when using
status.HTTP_403_FORBIDDEN and status.HTTP_404_NOT_FOUND.
Add exception handling in stop_wrap_console to gracefully handle
ConnectionResetError, BrokenPipeError, and OSError when waiting
for console writer to close.
This prevents 500 errors when stopping QEMU nodes if the console
connection is reset before the writer finishes closing.
Fixes race condition where QEMU process exits and closes connections
before the console writer cleanup completes.
Remove MD5 checksum calculation from the node files API since
disk image files are dynamic and change frequently. MD5 calculation
was also causing significant performance overhead.
Changes:
- Remove md5sum field from NodeFile schema
- Remove MD5 calculation from list_node_files method
- Improve error handling for timestamp conversion
- Simplify code by removing lambda functions
Performance improvement:
- Response time reduced from ~0.5-1s to ~0.017s (30-60x faster)
- Especially beneficial for large files and multiple files

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.

When closing a Docker node, if container deletion fails, the error
is silently ignored. This can lead to stale containers remaining on
the system and causing 409 conflicts when reopening projects.
Changes:
- Distinguish between 404 (container already removed, normal) and
other DockerError (deletion failed, needs attention)
- Log warning when deletion fails with error details
- Add comment explaining stale containers will be cleaned up on
project open (via automatic 409 conflict resolution)
This improves observability without blocking project close operations.
The root cause of stale containers can now be diagnosed from logs.
Fixes#2708

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.

When a Docker container with the same name already exists (e.g., from a
previous crashed GNS3 session), Docker returns a 409 Conflict error
when trying to create a new container with that name. This causes the
project open operation to fail.
This fix adds automatic cleanup of stale containers when encountering
a name conflict:
- Added DockerHttp409Error exception class
- Updated http_query to detect 409 status codes
- Modified create() to remove conflicting containers and retry
Fixes the issue where opening a project fails with:
"Docker has returned an error: 409 Conflict. The container name
'/GNS3.xxx' is already in use by container 'xxx'"
Add an additional fallback check for the VBoxManage executable using the capitalized "VBoxManage" command name. This improves compatibility on systems where the executable may be case-sensitive or installed with a different naming convention, ensuring the VirtualBox manager can locate the necessary binary when the lowercase "vboxmanage" is not found.
asyncio.get_running_loop() raises RuntimeError when emit() is called
from a thread without an active event loop (e.g. when the disk space
check in project_manager triggers a log.warning notification from a
threadpool worker).
This causes a 500 Internal Server Error on project creation/open when
disk usage is high, instead of the intended warning notification.
Wrap the emit loop in try/except RuntimeError so that notifications
are silently dropped when no event loop is available, rather than
crashing the request.
Fixes#2502Fixes#2505
On musl-based systems (Alpine), ldd returns exit code 0 for static
binaries, unlike glibc which returns 1. This causes install_busybox()
to reject all busybox binaries as "dynamically linked" on Alpine.
Fix by also accepting binaries whose executable name contains "static"
(i.e. busybox-static, busybox.static), which are the first two
candidates checked by the function. The generic "busybox" fallback
still relies on the ldd return code check.
