Downloads require an Authorization header, which <iframe>/<img> cannot
send. The previous blob: workaround broke under download managers (IDM
hooks blob URLs, fails to resolve them, and leaves a 0-byte file) and in
Chrome's mobile emulation, which has no inline PDF plugin.
Backend:
- preview_token.py: HMAC-signed token bound to one (quote, kind, file)
with a 5-minute TTL, keyed off an existing secret
- GET /quotes/{id}/preview-url/{kind}/{attachment} mints the URL
- the two file GET routes accept a Bearer session OR the signed ?t= token
(they leave the global auth dep, so the other six file routes now carry
it explicitly — nothing is open by omission)
Frontend:
- api.files.previewUrl() replaces the blob helper
- shared FilePreviewModal + useFilePreview; FileList and the dashboard
quote card both use it
- PDFs render with the browser's native viewer on desktop and pdf.js on
canvas where no inline viewer exists (mobile); pdf.js is fed the bytes
in memory so no PDF URL is exposed for a download manager to intercept
- removed the per-attachment download buttons on the dashboard card and
the modal header
Ops:
- nginx: explicit MIME types (.mjs as text/javascript) — a module worker
served as octet-stream is refused and crashed the page
- frontend service bypasses the nginx entrypoint, whose apk manifest call
hangs when the package mirror is unreachable (502s)
RUNTIME BUG (caught by live smoke tests): the global auth dependency
queried the request-scoped session, auto-beginning its transaction — any
endpoint opening 'async with db.begin()' afterwards crashed with
'transaction already begun' (POST /materials 500). get_current_user /
get_actor now resolve in a short-lived session (expire_on_commit=False
keeps the context usable detached); inventory/pm scopes keep passing the
request session explicitly.
Smoke suites rewritten against CURRENT contracts:
- assertions are behavior-based (shapes, envelopes, filters), no magic
seed counts; dynamic lookups instead of hard-coded names/ids
- rerun-tolerant: tolerate 409-on-create by reusing prior artifacts
- aligned with current rules: revert blocked after inventory receipts
(v2.6), attachments allowed in every status, termsheets optional at
quote level
- SMOKE_USER/SMOKE_PASSWORD env for login (default tester/123456)
Verified on a fresh volume: migration + audit_log bootstrap, Casdoor
seed (bcrypt), demo data, and 29+76+61 smoke checks all green.
- slowapi limiter on POST /auth/login (10/min per IP, Persian error msg);
edge-level coarse limits stay in Traefik
- mem_limit on every main-compose service (~4.4GB worst case, protects the
8GB shared host during rebuilds)
- monitoring images pinned to verified tags (prom v3.4.1, grafana 11.6.3,
loki/promtail 3.5.0, node-exporter v1.9.1, postgres-exporter v0.17.1,
cadvisor v0.49.1); exporter image name fixed to postgres-exporter
- db-backup sidecar: pg_dump -Fc of procurement+casdoor every
BACKUP_INTERVAL_SECONDS into BACKUP_DIR, retention via BACKUP_KEEP_DAYS
- audit_log table (migration.sql + runtime ensure_audit_table) with
model + transactional helper (utils/audit.record) — wired into user
create/role-change and inventory transaction creation
- get_actor: quote_events.actor now stores the VERIFIED user's display
name instead of the raw bearer token
- verify kid from the JWT header (pyjwt decode() returns claims, not the
header — the old lookup was always None and rejected every token)
- convert JWK entries to crypto keys explicitly (pyjwt 2.13 dropped dict
keys) and fetch the JWKS from /.well-known/jwks
- 401 for missing/invalid/expired/wrong-issuer/wrong-audience tokens
(was 403/400); 403 stays for valid-but-roleless users; 503 when Casdoor
is unreachable; new CASDOOR_ISSUER setting separates the in-network
endpoint from the browser-facing issuer
- dev-header fallback in inventory/pm scopes now requires an explicit
X-User-Role header (no auth info at all -> 401)
- new POST /api/v1/auth/login: password grant against Casdoor, local JWT
verification, auto-provisioning, returns token + profile with the role
resolved from the app users table
