Always render <select> even for single-model drivers — simplifies template logic and consistent UI
Dynamic DRIVERS_DIR read (import config module, not top-level constant) so monkeypatch works in tests
TestClient context manager in conftest client fixture — required for lifespan/init_db to trigger in integration tests
HTMX-friendly 400 error: return HTMLResponse with <div id='driver-list'> wrapper so HTMX can swap error inline
HTMX partial pattern: upload returns <div id='driver-list'> fragment; page has matching hx-target; outerHTML swap replaces entire div
driver_data pattern: routes build list of dicts with {'driver': orm_obj, 'names': list[str]} to pre-parse JSON in Python rather than Jinja2
Config monkeypatch: endpoints import config module (not constants) so test fixtures can override DRIVERS_DIR/DB_PATH

Phase 02 Plan 02: Driver Upload Endpoint Summary

HTMX-driven driver ZIP upload with INF parsing, SHA256 dedup, Peewee persistence, and select dropdown returning 8/8 integration tests green

Performance

  • Duration: ~3 min
  • Started: 2026-04-10T10:18:52Z
  • Completed: 2026-04-10T10:22:00Z
  • Tasks: 2 (Task 1 TDD: RED + GREEN; Task 2 templates completed inline)
  • Files modified: 7

Accomplishments

  • POST /drivers/upload: validates ZIP, finds INF, parses via INF parser service, saves via DriverStore (SHA256 content-addressed), upserts Driver record with json.dumps(driver_names) in driver_desc — full dedup on re-upload
  • GET /drivers page renders upload form with HTMX attributes and existing driver library table
  • HTMX partial (partials/driver_list.html): wraps content in <div id="driver-list"> for outerHTML swap; shows unused-file notice with count and expandable list; renders driver names as <select> dropdown
  • 8 integration tests written TDD-first (RED commit, then GREEN): page render, valid upload, non-ZIP 400, no-INF 400, select presence, DB persistence, dedup, unused files in response

Task Commits

  1. Test RED phase: failing integration tests - 8ecfbf2 (test)
  2. Task 1 + Task 2: upload endpoint, templates, pages route, router registration - c648fc5 (feat)

Files Created/Modified

  • imptune/api/drivers.py - POST /drivers/upload endpoint with full validation, INF parsing, DriverStore save, Peewee get_or_create
  • imptune/api/pages.py - Added GET /drivers route with driver_data context
  • imptune/main.py - Registered drivers.router
  • imptune/templates/drivers.html - Drivers page extending base.html with HTMX upload form
  • imptune/templates/partials/driver_list.html - HTMX swap target with table, select dropdown, unused-files notice
  • tests/test_driver_upload.py - 8 integration tests covering all success and error paths
  • tests/conftest.py - Fixed client fixture to use TestClient as context manager

Decisions Made

  • Always render <select> even for single driver name — uniform UI and simpler template logic
  • Read _cfg.DRIVERS_DIR dynamically (not top-level constant import) so test monkeypatching works
  • TestClient(app) must be used as a context manager for Starlette 0.46+ to trigger lifespan and run init_db()
  • HTMX errors: return HTMLResponse with <div id='driver-list'> wrapper at status 400 so HTMX can swap error into target area

Deviations from Plan

Auto-fixed Issues

1. [Rule 3 - Blocking] TestClient context manager required for lifespan trigger

  • Found during: Task 1 GREEN (first test run)
  • Issue: TestClient(app) without context manager does not run lifespan in Starlette 0.46+, so init_db() never called; DB remained deferred (None), causing InterfaceError on all ORM queries
  • Fix: Changed conftest client fixture from return TestClient(app) to with TestClient(app) as c: yield c
  • Files modified: tests/conftest.py
  • Verification: All 48 tests pass including pre-existing health, static, DB, and parser tests
  • Committed in: c648fc5 (Task 1 feat commit)

2. [Rule 1 - Bug] Dynamic DRIVERS_DIR read to support monkeypatch

  • Found during: Task 1 GREEN (test_driver_persisted failure)
  • Issue: from imptune.config import DRIVERS_DIR captured the value at import time; tests patching cfg.DRIVERS_DIR had no effect — files written to /data/drivers (production path) not the tmp dir
  • Fix: Changed to import imptune.config as _cfg and use _cfg.DRIVERS_DIR at call time
  • Files modified: imptune/api/drivers.py
  • Verification: test_driver_persisted passes; file found in tmp_data_dir/drivers/
  • Committed in: c648fc5 (Task 1 feat commit)

3. [Rule 1 - Bug] Template always renders <select> for any non-empty names list

  • Found during: Task 1 GREEN (test_upload_returns_select failure)
  • Issue: Template only showed <select> for multiple names; sample INF has 1 driver name, so test failed
  • Fix: Changed template condition from {% if item.names | length > 1 %} to {% if item.names %}
  • Files modified: imptune/templates/partials/driver_list.html
  • Verification: test_upload_returns_select passes
  • Committed in: c648fc5 (Task 1 feat commit)

Total deviations: 3 auto-fixed (1 Rule 3 blocking, 2 Rule 1 bugs) Impact on plan: All three fixes necessary for correct test isolation and behavior. No scope creep.

Issues Encountered

None beyond the three auto-fixed deviations above.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

  • Driver upload feature fully functional: upload, parse, persist, dedup, UI feedback
  • Driver records in SQLite with driver_desc (JSON list), architecture, inf_filename, has_cat_file
  • Phase 03 (printer management) can reference drivers via Driver model and driver select dropdowns
  • Phase 04 (package generation) can read persisted driver ZIPs from DriverStore using sha256
