Replace credential auto-login with a Chrome-remote-debugging session capture flow
Live testing against the real site found MassPrice's login is behind
hCaptcha, which silently blocks fully automated username/password
login outright (the form never submits) — no selector fix could work
around this. Also fixed the broken _is_logged_out() heuristic: an
unauthenticated visit to /Rule/List redirects to the public marketing
homepage, not a /login URL, so run_rule/list_rules were silently
scraping the wrong page instead of erroring.

New flow: a Session page lets the user start a headless-but-CDP-exposed
Chromium instance, log in themselves via chrome://inspect (solving the
captcha as a real click), then capture that browser's cookies into the
same auth_state.json scheduled runs already use. Required a socat proxy
in the container image, since Chromium's debug port binds loopback-only
regardless of --remote-debugging-address (confirmed by live testing),
unreachable through Docker's port mapping without it. All Playwright
objects for this now live on one dedicated thread (automation.py's
_debug_worker), since the sync API isn't safe to call across the
arbitrary threads gunicorn's gthread workers hand out per request.

Dashboard now shows a banner when the latest run failed specifically
due to a missing/expired session, rather than just looking like an
empty rule list.

name description
deploy-massprice Use when deploying MassPrice Scheduler, restarting the massprice container on Unraid, confirming a deploy landed, logging into MassPrice via the Session page, or troubleshooting its scheduled-rule automation.

Deployment

Target: Unraid server, container path /mnt/user/appdata/massprice, built from Dockerfile/docker-compose.yml in this repo. Container name massprice, port 5057 (overridable via HOST_PORT — 5056 was already taken by arr-summary, despite its own docs saying 5055) → container port 5000. Also exposes DEBUG_PORT (default 9222) for the Chrome-remote-debugging login flow — see below.

Deploy mechanism: Forgejo push-to-deploy, the same pattern as arr-summary, card-grader, lunch-notifier, n64-tracker — see arr-summary's deploy-arr-summary skill or card-grader's CLAUDE.md for the full runner mechanics. Push to main on the forgejo remote (https://git.hippofam.com/ninja_hippo/massprice.git) triggers .forgejo/workflows/deploy.yml, which syncs into /mnt/user/appdata/massprice (excluding .git, .env, data/) and runs docker compose up -d --build.

Restarting the container manually: use Compose, not the Unraid Docker UI — same reasoning as the other projects (every deploy recreates the container with a new Docker ID; Unraid's UI caches the old one). From the Unraid terminal:

cd /mnt/user/appdata/massprice && docker compose restart

docker compose up -d --force-recreate for a guaranteed-clean recreate; docker ps --filter name=massprice to check real state.

Confirming a deploy landed: the footer renders v<APP_VERSION> · <APP_VERSION_DATE> from constants near the top of app.py. Bump them every commit.

First deploy checklist

  1. Create /mnt/user/appdata/massprice on Unraid and a real .env there (copy .env.example, fill in LOGIN_PASSWORD, SECRET_KEY, HOST_PORT, DEBUG_PORT, TZ).
  2. First docker compose up -d --build — confirm the container starts and /login responds on HOST_PORT.
  3. Log into the webui, go to the Session page, and follow its instructions: click "Start Login Session", connect your own Chrome to <unraid-ip>:<DEBUG_PORT> via chrome://inspect, log in (solving the hCaptcha yourself — this cannot be automated, see CLAUDE.md), then click "Capture Session" back in the webui.
  4. Click "Refresh Rules" on the Dashboard — confirms the saved session actually works and pulls the real rule list.
  5. Set up at least one schedule and use "Run Now" once to confirm a click actually lands — cross-check by looking at MassPrice's own Activity Log (https://massprice.tcgplayer.com/Activity/List) for a fresh timestamp on that rule.
  6. Only after step 5 succeeds, go to each existing rule on massprice.tcgplayer.com (three-dot menu → Edit Schedule) and set Status to Inactive, so native scheduling stops double-triggering runs and this tool becomes the sole source of scheduled runs.

Persistent state, never touched by deploys

.env holds LOGIN_PASSWORD and SECRET_KEY. data/ (bind-mounted to /data) holds schedules.json (the schedules set from the webui), auth_state.json (the saved MassPrice browser session captured via the Session page — losing this just costs one re-login, not data), run_history.json, and rules_cache.json. Both are excluded from the deploy rsync (which runs --delete) and from git.

If scheduled runs stop working

Check, in order:

  1. Dashboard banner / Activity page — a "session expired or missing" message means go log in again via the Session page. "rule id not found" means a rule was renamed/deleted on MassPrice — click "Refresh Rules".
  2. Is the container still running — docker ps --filter name=massprice — a Chromium crash inside the container (rare, but possible if shm_size ever gets dropped from docker-compose.yml) would show as the container restarting.
  3. Timezone — TZ in .env controls what "6:00 AM" means for every schedule; confirm it matches what the user actually expects before assuming a schedule itself is wrong.
  4. Session capture stuck at "Still not logged in" — the debug session's page needs to actually be on /Rule/List or somewhere under /Rule after login for the capture check to pass; if the inspected tab is still sitting on the marketing homepage or the OAuth login page, finish clicking through to the dashboard/rules first.
