Reporter @iitazz uploaded slicer output to Bambuddy, clicked Print,
and the printer rejected every job with "Printing stopped because
the printer was unable to parse the 3mf file". Support bundle showed
the stored library file ended in .gcode (not .gcode.3mf), and
background_dispatch.py appends ".3mf" to filenames that don't
already end in .gcode.3mf/.3mf — so raw gcode shipped to the printer
named .gcode.3mf and the firmware's 3MF parser choked. Same shape
also surfaced as "File is not a zip file" on Bambuddy's own plate
parser.
New validate_print_file_upload() helper in library.py runs at upload
time:
- Reject filenames ending in .gcode (but not .gcode.3mf) with a
clear message — Bambu printers need .gcode.3mf zip containers,
not raw gcode.
- For .3mf / .gcode.3mf uploads, verify body starts with PK\x03\x04
(ZIP magic); reject otherwise pointing at the slicer's "Export
Plate Sliced File" action.
Applied to every relevant upload route: POST /library/files (covers
File Manager + printer-card drag-drop), POST /archives/upload,
POST /archives/upload-bulk (rejects per-row so one bad file doesn't
abort the batch), POST /archives/{id}/source, POST /archives/upload-source.
Runs after _resolve_upload_destination so folder-permission errors
(403 readonly, 400 missing-path, 409 collision) still take precedence.
STL / image / other non-print uploads bypass the validator.
FileUploadModal frontend fix: the modal auto-closed after every
batch regardless of per-file results, so a 400 rejection was captured
but invisible. Now:
- Errors render inline as red text under the file row instead of
as a hover-only title tooltip.
- Modal stays open if any file ended with status='error', so the
user can read the backend's remediation message before closing.
- Successful-only batches still auto-close as before.
UploadModal (bulk archive) was already showing inline errors and
not auto-closing — no change needed there.
Audit PRs #920 (printers search/filter) and #932 (print from project
view) for regressions, i18n coverage, test gaps, and docs.
No regressions found: existing callers of the changed signatures
(archive_print, getLibraryFiles, filteredPrinters chain) are unaffected;
i18n is complete in all 7 locales for both features.
Backend tests (4 new, all passing):
- test_list_files_by_project_id — bulk JOIN returns files across all
linked folders, excludes unlinked ones
- test_list_files_folder_id_takes_precedence_over_project_id — guards
the documented precedence folder_id > project_id > include_root
- test_add_to_queue_with_project_id — project_id is persisted on the
queue row for later archive linkage
- test_add_to_queue_invalid_project_id_returns_404 — regression guard
for the validation pre-check on the queue path (mirrors the one on
the direct-print path in library.py)
These modules were already imported at the top of each file.
Removes re-imports of re, json, zipfile, and logging from
inside functions in archive.py, library.py, main.py,
printers.py, support.py, and test_library_api.py.
Resolves all 30 CodeQL py/repeated-import findings.
The File Manager (Library) backend had no permission enforcement - endpoints were returning data to any authenticated user regardless of their group permissions.
Closes#224
Track and display who performs key actions in Bambuddy:
- Archives: who uploaded each archive file
- Library: who uploaded each file in File Manager
- Queue: who added each print job to the queue
- Printers: who started the current print (reprint tracking)
Backend changes:
- Add created_by_id column to print_archives, library_files, print_queue tables
- Add database migrations for new columns (auto-run on startup)
- Update archive, library, and queue routes to capture current user
- Add current-print-user endpoint for printer reprint tracking
- Track reprint user in PrinterManager in-memory state
- Fix file uploads not sending auth headers (FormData requires explicit headers)
Frontend changes:
- Display username on archive cards, library files, queue items
- Show "Started by" on printer cards during active prints
- Add auth headers to all 12 FormData upload functions
- Update TypeScript types for user tracking fields
Tests:
- Add unit tests for PrinterManager user tracking methods (7 tests)
- Add integration tests for current-print-user endpoint (3 tests)
- Add integration tests for library file user tracking (3 tests)
Works when authentication is enabled; gracefully hidden when disabled.
Closes#206
- Implemented batch STL thumbnail generation API endpoint.
- Added Pydantic schemas for batch thumbnail requests and responses.
- Created service for generating thumbnails from STL files using trimesh and matplotlib.
- Updated file upload and ZIP extraction endpoints to include thumbnail generation option.
- Enhanced frontend to support STL thumbnail generation during file uploads and ZIP extractions.
- Added integration and unit tests for the new thumbnail generation features.
- Updated requirements to include necessary libraries for STL processing.
File Manager improvements (#121):
- New option to create folder from ZIP filename (e.g., MyProject.zip → MyProject/)
- Upload modal now accepts all file types, not just ZIP files
- Updated drop zone text to clarify all files are supported
- Both options can be combined: create folder + preserve internal structure
Camera zoom/pan improvements (#132):
- Pan range now based on actual container size instead of fixed pixels
- Users can pan across the entire zoomed image at any zoom level
- Added pinch-to-zoom gesture for mobile (two fingers)
- Added single finger pan when zoomed in on touch devices
- Pan while pinching to reposition zoom focus
- Both EmbeddedCameraViewer and standalone CameraPage updated
Features:
- ZIP file support in File Manager (Issue #121): Upload ZIP files to
automatically extract contents with option to preserve folder structure
- Delete operation loading indicator: Shows progress during folder/file
deletion operations
Fixed:
- Print time stats using actual elapsed time instead of slicer estimates
(Issue #137)
- Skip objects modal overflow with scrollable list for many objects
(Issue #134)
Removed:
- Duplicate badge feature from File Manager (per user request)
Tests:
- Added ZIP extraction backend tests (5 tests)
- Added ConfirmModal loading state frontend tests (5 tests)
- New RenameModal component with validation
- Backend endpoint supports filename updates (rejects path separators)
- Context menu "Rename" option in grid and list views
- Inline rename button in list view actions
- Add Print button to multi-selection toolbar:
- Appears when exactly one sliced file is selected
- Opens full PrintModal with plate selection and options
- Add to Queue button now uses Clock icon for clarity
- Improve mobile/PWA accessibility:
- Three-dot menu button always visible on mobile (md:opacity-0)
- Selection checkbox always visible on touch devices
- Better experience for PWA users on tablets and phones
Closes#94
