Dashboard (dashboard/src/dashboard.tsx, settings.tsx, apiAcademicPeriods.ts):
- Refactor loadHolidayStatus to useCallback with stable empty-deps reference;
removes location.pathname dependency that caused overlapping API calls at mount
and left the banner unresolved via request-sequence cancellation
- Add key prop derived from severity:text to Syncfusion MessageComponent to force
remount on state change, fixing stale banner that ignored React prop/children updates
- Correct German transliterated text to proper Umlauts throughout visible UI strings
(fuer -> für, oe -> ö, ae -> ä etc. across dashboard and settings views)
Backend (server/init_academic_periods.py):
- Refactor to idempotent two-phase flow: seed default periods only when table is
empty; on every run activate exactly the non-archived period covering date.today()
- Enforces single-active invariant by deactivating all periods before promoting match
- Emits explicit warning when no period covers current date instead of doing nothing
Deployment (docker-compose.prod.yml):
- Add init_academic_periods.py to server startup chain after migrations and defaults;
eliminates manual post-deploy step to set an active academic period
Release docs:
- program-info.json: bump to 2026.1.0-alpha.16; fix JSON parse error caused by
typographic curly quotes in the new changelog entry
- TECH-CHANGELOG.md: detailed alpha.16 section with root-cause motivation for both
dashboard refactoring decisions (unstable callback ref + Syncfusion stale render)
- DEV-CHANGELOG.md: document dashboard refactor, Syncfusion key fix, Umlaut changes,
and program-info JSON regression and fix
- README.md: add Latest Release Highlights section for alpha.16
- .github/copilot-instructions.md: sync file map, prod bootstrap note, backend and
frontend pattern additions for academic period init and Syncfusion remount pattern
Dashboard
Add top-right user dropdown using Syncfusion DropDownButton: shows username + role; menu entries “Profil” and “Abmelden”.
Replace custom dropdown logic with Syncfusion component; position at header’s right edge.
Update /logout page to call backend logout and redirect to /login (reliable user switching).
Build/Config
Add @syncfusion/ej2-react-splitbuttons and @syncfusion/ej2-splitbuttons dependencies.
Update Vite optimizeDeps.include to pre-bundle splitbuttons and avoid import-analysis errors.
Docs
README: Rework Architecture Overview with clearer data flow:
Listener consumes MQTT (discovery/heartbeats) and updates API.
Scheduler reads from API and publishes events via MQTT to clients.
Clients send via MQTT and receive via MQTT.
Worker receives commands directly from API and reports results back (no MQTT).
Explicit note: MariaDB is accessed exclusively by the API Server; Dashboard never talks to DB directly.
README: Add SplitButtons to “Syncfusion Components Used”; add troubleshooting steps for @syncfusion/ej2-react-splitbuttons import issues (optimizeDeps + volume reset).
Copilot instructions: Document header user menu and splitbuttons technical notes (deps, optimizeDeps, dev-container node_modules volume).
Program info
Bump to 2025.1.0-alpha.10 with changelog:
UI: Header user menu (DropDownButton with username/role; Profil/Abmelden).
Frontend: Syncfusion SplitButtons integration + Vite pre-bundling config.
Fix: Added README guidance for splitbuttons import errors.
No breaking changes.
