From e097b504af193963ab46e3d158127b01962a33fe Mon Sep 17 00:00:00 2001 From: malice Date: Sun, 17 May 2026 18:04:23 -0600 Subject: [PATCH] feat(gui): add streams view (1b-6) (#21) * feat(gui): add streams view (1b-6) Add streams list and edit routes with live JetStream data: - GET /streams: list all streams with live size/messages - POST /streams/{name}: update max_age_s with validation Features: - Live data from JetStream (bytes, messages, timestamps) - Graceful degradation when NATS unavailable - Preset chip buttons (1d, 7d, 14d, 30d, 365d) - Custom days input with Save button - Current selection highlighted - Managed by supervisor badge - Audit logging with before/after max_age_s Files: - src/central/gui/audit.py: add STREAM_UPDATE constant - src/central/gui/routes.py: add streams_list and streams_update handlers - src/central/gui/templates/base.html: add Streams nav link - src/central/gui/templates/streams_list.html: new template - tests/test_streams.py: 9 tests covering all requirements Co-Authored-By: Claude Opus 4.5 * fix(gui): use get_msg().time for stream timestamps, fix badge layout - nats-py StreamState doesn't expose first_ts/last_ts - Fetch timestamps via js.get_msg(stream, seq=N).time instead - Handle edge cases: empty streams, single-message streams, get_msg failures - Fix badge overlap using flex layout instead of float:right - Change label from "Max bytes (config)" to "Max bytes (current)" Co-Authored-By: Claude Opus 4.5 --------- Co-authored-by: Matt Johnson Co-authored-by: Claude Opus 4.5 --- src/central/gui/audit.py | 1 + src/central/gui/routes.py | 232 ++++++++ src/central/gui/templates/base.html | 1 + src/central/gui/templates/streams_list.html | 92 +++ tests/test_streams.py | 589 ++++++++++++++++++++ 5 files changed, 915 insertions(+) create mode 100644 src/central/gui/templates/streams_list.html create mode 100644 tests/test_streams.py diff --git a/src/central/gui/audit.py b/src/central/gui/audit.py index 7d2f8f1..6992537 100644 --- a/src/central/gui/audit.py +++ b/src/central/gui/audit.py @@ -10,6 +10,7 @@ AUTH_LOGOUT = "auth.logout" AUTH_PASSWORD_CHANGE = "auth.password_change" OPERATOR_CREATE = "operator.create" ADAPTER_UPDATE = "adapter.update" +STREAM_UPDATE = "stream.update" async def write_audit( diff --git a/src/central/gui/routes.py b/src/central/gui/routes.py index d548306..10c6b2e 100644 --- a/src/central/gui/routes.py +++ b/src/central/gui/routes.py @@ -1,9 +1,12 @@ """Route handlers for Central GUI.""" import json +import logging import re from typing import Any +logger = logging.getLogger("central.gui.routes") + from fastapi import APIRouter, Depends, Form, Request from fastapi.responses import HTMLResponse, RedirectResponse, Response from fastapi_csrf_protect import CsrfProtect @@ -22,6 +25,7 @@ from central.gui.audit import ( AUTH_LOGOUT, AUTH_PASSWORD_CHANGE, OPERATOR_CREATE, + STREAM_UPDATE, write_audit, ) from central.gui.db import get_pool @@ -872,3 +876,231 @@ async def adapters_edit_submit( ) return RedirectResponse(url="/adapters", status_code=302) + + +# ============================================================================= +# Streams routes +# ============================================================================= + + +@router.get("/streams", response_class=HTMLResponse) +async def streams_list( + request: Request, + csrf_protect: CsrfProtect = Depends(), +) -> HTMLResponse: + """List all streams with live data.""" + from central.gui.nats import get_js + + templates = _get_templates() + pool = get_pool() + operator = request.state.operator + js = get_js() + + async with pool.acquire() as conn: + rows = await conn.fetch( + """ + SELECT name, max_age_s, max_bytes, managed_max_bytes, updated_at + FROM config.streams + ORDER BY name + """ + ) + + streams = [] + for row in rows: + stream_data = { + "name": row["name"], + "max_age_s": row["max_age_s"], + "max_bytes_cfg": row["max_bytes"], + "managed_max_bytes": row["managed_max_bytes"], + "live_bytes": None, + "live_messages": None, + "live_first_seq": None, + "live_last_seq": None, + "live_first_ts": None, + "live_last_ts": None, + "first_ts_error": None, + "last_ts_error": None, + "error": None, + } + + #
