Service ops.\ntriggers:\n - tcharts\n - tcharts not updating\n - tcharts errors\n - charting-project\n---\n\n# TCharts Server Operations\n\nTCharts = Rust (axum + rusqlite) renko chart platform at\nhttps://tcharts.openalgo.theworkpc.com. systemd unit `tcharts.service`,\nport 5101. Single source file: `/home/ubuntu/charting-project/src/main.rs`\n(~1550 lines). Static frontend: `/home/ubuntu/charting-project/static/`\n(served by nginx directly; nginx proxies only `/api/` to 127.0.0.1:5101 with\n`proxy_read_timeout 30s`). Computed DBs live under\n`/home/ubuntu/charting-project/dbs/`.\n\nRelated: `tcharts-daily-indicator-overlay` skill for chart-UI work (daily\nlines, last-price legend, right-edge label queue — read before touching\n`static/index.html`; static edits go live without a restart, verify with\nmd5 served-vs-disk).\n\n## Architecture (REBUILT Aug 11, 2026 — incremental append + hot/cold tiers)\n\n- `#[tokio::main]` multi-thread. Boot: `fill_symbol()` for every symbol\n (~4s total — incremental), then `run_watcher()` every 60s via tokio::spawn.\n- **Incremental append**: `fill_symbol()` rebuilds bricks + indicators in\n memory from full history (fast, deterministic), then compares the DB tail\n (`MAX(brick_index)` + close). Match → INSERT only newer rows. Mismatch or\n empty table → DELETE + rebuild THAT INTERVAL only. Everything for one\n interval in ONE transaction. No global DELETEs — old rows never rewritten\n (raw 5-min candles are immutable, so bricks/snapshots are append-only).\n- **WAL mode + busy_timeout(15s)** on writer (fill_symbol) and readers\n (`open_computed`, `read_5min_db`) — API never blocks or sees partial data.\n- **Hot/cold tiers**: browser POSTs `/api/watch {\"symbol\":\"SBIN\"}` every 30s\n while the page is open. Watcher: HOT symbols (heartbeat < 3 min) recompute\n every cycle when the raw 5-min DB mtime is newer (>5s grace); COLD symbols\n only every 15th cycle. `ensure_fresh()` at the top of every computed-DB\n reader endpoint (`api_bricks/snapshots/daily_values/xover_events/\n daily_signal`) fills on-demand when stale (FILL_LOCK mutex + spawn_blocking)\n — first open of a cold symbol costs ~0.5-2s once, then it's hot.\n- **Incremental API**: `/api/bricks/<sym>?interval=5m&since=<brick_index>&\n limit=<N>` — `since` returns only newer bricks, `limit` returns last N;\n response includes `max_index`. Works on both the pre-computed path and the\n custom-brick_size on-the-fly path.\n- **Frontend**: initial load fetches `limit=max(2000, bars*2)` bricks (not\n full history — BANKNIFTY has 284k); then `refreshIncremental()` every 60s\n appends `since=<lastIdx>` + refreshes snapshot tail (limit=500) +\n daily-values

Also: the systemd service is DEAD since Aug 16 21:27 and the thing serving :5101 is a stray manual debug process with logs going to a dead pipe. Let me fix this properly~

The sync script doesn't touch sbin (0 developing_daily rows) — so SBIN's 12:36 update WAS a real fill, and fills stopped working right after. Logs from the stray process are unrecoverable (pipe has no live reader). Restart under systemd is the move — checking the build:

Fixed~ (◕‿◕)★ HAL renko is plotting again, live through 13:35 today.
What was wrong:
1. The systemd service tcharts.service was dead since Aug 16 21:27 — a manual debug process was left running instead, with all its logs going to a dead pipe. Its fill/watcher machinery silently died (~12:36 today) and NO computed DB updated after that. The API kept serving frozen Aug-14 bricks while raw candles kept flowing — so the chart showed nothing new.
2. The release binary the service would have started was also stale (built Aug 11, pre-incremental code).
What I did:
1. Rebuilt release from current source (6.9s).
2. Killed the stray process, started tcharts.service under systemd.
3. Boot fill: all 15 symbols OK — HAL 95,482 bricks in 0.4s. First watcher cycle: 14 ok / 0 failed, HAL recomputed as hot (+16 new bricks already).
4. Verified: /api/bricks/HAL now returns bricks through 13:35 (max 44392, close 5078), snapshot RSI 35.71, VIDYA 5084.65. Also removed a junk 0-byte HAL_computed.db (uppercase) some script left at 13:31 — harmless, tcharts ignores it.
5. Saved the whole diagnosis to the tcharts skill so this doesn't recur.
One thing you need to do: hard-refresh the HAL chart (Ctrl+Shift+R) — your browser is still showing the old frozen page cache.
Want me to keep an eye on the watcher for the next few cycles to confirm it stays healthy through close?
