Fixes from the PR #23 adversarial review (graded 35 real / 1 false positive): Security / correctness - Race-free registration: is_admin and the registration gate are now computed atomically inside a single INSERT...SELECT, so concurrent first registrations can't both become admin or bypass closed registration (fixed the whole TOCTOU cluster). - Sliding session now reaches the browser: ResolveSession returns the current expiry and requireAuth re-sets the cookie, so active users aren't logged out 30 days after login regardless of activity. - Login CSRF: csrfGuard rejects state-changing requests whose Origin doesn't match PANSY_BASE_URL (no-op when unset, so the dev proxy is unaffected). SameSite=Lax alone didn't cover this. - argon2id tuned to RFC 9106's second recommended profile (t=3). - Timing equalizer can't fail open: the dummy hash is derived deterministically (fixed salt, no RNG) so it's always present. - Password length (<=1024) enforced in the service for both register and login, not just HTTP binding tags; login rejects over-long input before spending argon2 work. Error handling / robustness - Login logs a malformed stored hash instead of silently treating it as a wrong password. - Best-effort session writes (Touch/Delete during renewal, expiry, and corrupt-expiry cleanup) now log on failure. - index sessions.expires_at via new migration 0002 (0001 is immutable). Maintainability - Extract startSessionAndRespond and abortUnauthenticated; make writeServiceError a free function; consistent error handling in decodeHash; doc/comment fixes. Tests: over-long password, CSRF guard (cross-origin/same-origin/dev no-op), and cookie refresh on authenticated requests; migration-version assertions bumped to 2.

pansy
Self-hostable garden planner: drag beds, bags, and containers onto a real-scale field, click into them to place freeform plops of plants, and zoom out to see what's planted where. Go backend + React frontend, one static binary.
See DESIGN.md for the architecture. Work is tracked in this repo's issues — start from the tracking epic.
Quickstart
Prerequisites: Go 1.26+, Node 20+.
Develop
Run the Go API and the Vite dev server together (Vite proxies /api → the API):
make dev
Then open http://localhost:5173. Or run the two halves in separate terminals for independent restarts:
make dev-api # Go API on :8080
make dev-web # Vite dev server on :5173
Build & run
Produce the single static binary with the web build embedded, then run it:
make build
./pansy
Open http://localhost:8080 — one process serves both the JSON API and the app.
Test
make test
Configuration
All configuration is via environment variables; every value has a default, so ./pansy runs with none set.
| Variable | Default | Description |
|---|---|---|
PANSY_PORT |
8080 |
TCP port the HTTP server listens on. |
PANSY_DB |
./pansy.db |
SQLite database file path (created if absent). |
PANSY_BASE_URL |
(empty) | Externally-visible base URL; used to derive the OIDC redirect URI. |
PANSY_REGISTRATION |
open |
open or closed — gates local self-service signup. |
PANSY_LOCAL_AUTH |
true |
Enable local password auth. Set false for pure-OIDC. |
PANSY_OIDC_ISSUER |
(empty) | OIDC issuer/discovery URL (Authentik). Enables SSO when set. |
PANSY_OIDC_CLIENT_ID |
(empty) | OIDC client ID. |
PANSY_OIDC_CLIENT_SECRET |
(empty) | OIDC client secret. |
PANSY_OIDC_BUTTON_LABEL |
Sign in with SSO |
Label for the OIDC button on the login page. |
PANSY_TRUSTED_PROXIES |
(none) | Comma-separated proxy CIDRs/IPs to trust for client-IP resolution. |
Local email/password auth is live (POST /api/v1/auth/register, /auth/login, /auth/logout, GET /auth/me, GET /auth/providers); the session is an HttpOnly cookie (Secure when PANSY_BASE_URL is https). The first account registered becomes admin, and it may register even when PANSY_REGISTRATION=closed to bootstrap the instance. OIDC (PANSY_OIDC_*) lands in #5.
Docker & deployment
CI (.gitea/workflows/build-image.yml) builds the single-binary image and pushes it to the Gitea registry on every branch push:
| Ref | Tag |
|---|---|
main |
gitea.stevedudenhoeffer.com/steve/pansy:latest |
| any other branch | gitea.stevedudenhoeffer.com/steve/pansy:<branch-name> |
| every build | gitea.stevedudenhoeffer.com/steve/pansy:sha-<short> (immutable; use to pin) |
The image runs as a non-root user, serves on :8080, and stores the SQLite database on the /data volume. Run it directly:
docker run -d --name pansy \
-p 8080:8080 \
-v pansy-data:/data \
gitea.stevedudenhoeffer.com/steve/pansy:latest
Or as a Komodo/Compose stack:
services:
pansy:
image: gitea.stevedudenhoeffer.com/steve/pansy:${PANSY_TAG:-latest}
ports:
- "8080:8080"
volumes:
- pansy-data:/data
environment:
PANSY_BASE_URL: https://pansy.example.com
# PANSY_OIDC_ISSUER: ... # once auth (#5) lands
restart: unless-stopped
volumes:
pansy-data:
Pin PANSY_TAG to a sha-<short> tag for reproducible deploys, or leave it at latest to track main.
