From df7328026fb5b15d88217999b2ed0f713865d583 Mon Sep 17 00:00:00 2001 From: FriederikeHanssen Date: Tue, 23 Dec 2025 09:10:10 +0100 Subject: [PATCH 1/3] Fix workflow-monitor to support concurrent workflow monitoring MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The workflow-monitor node had a critical design flaw preventing it from monitoring multiple workflows simultaneously. When multiple workflow messages arrived in quick succession, only the most recent workflow would be monitored, causing earlier workflows to be dropped from tracking. Root causes: - Single shared intervalId variable - new workflows cleared previous intervals - Captured message context in closures - new messages replaced old contexts - clearPolling() on every input - stopped all active monitoring Solution: - Replace single intervalId with Map-based tracking (activeWorkflows) - Each workflow gets independent polling with its own interval - Preserve message context (correlationId, _context, etc.) per workflow - Only clear polling for specific workflows when they reach terminal state - Show workflow count in status display when monitoring multiple workflows - If same workflowId is triggered twice, replace the old monitor Tests added: - Verify multiple workflows can be monitored independently - Verify message context is preserved for each workflow separately - Verify proper cleanup when same workflowId is re-triggered This enables use cases like batch workflow launching where multiple pipelines need to be monitored through completion simultaneously. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 --- nodes/workflow-monitor.js | 109 ++++++++++----- test/workflow-monitor_spec.js | 250 ++++++++++++++++++++++++++++++++++ 2 files changed, 327 insertions(+), 32 deletions(-) diff --git a/nodes/workflow-monitor.js b/nodes/workflow-monitor.js index 377746e..862cd38 100644 --- a/nodes/workflow-monitor.js +++ b/nodes/workflow-monitor.js @@ -27,17 +27,27 @@ module.exports = function (RED) { return `${d.getFullYear()}-${pad(d.getMonth() + 1)}-${pad(d.getDate())} ${d.toLocaleTimeString()}`; }; - let intervalId = null; + // Track multiple workflows: Map + const activeWorkflows = new Map(); + + const clearPolling = (workflowId) => { + if (workflowId && activeWorkflows.has(workflowId)) { + const workflow = activeWorkflows.get(workflowId); + if (workflow.intervalId) { + clearInterval(workflow.intervalId); + } + activeWorkflows.delete(workflowId); + } + }; - const clearPolling = () => { - if (intervalId) { - clearInterval(intervalId); - intervalId = null; + const clearAllPolling = () => { + for (const [workflowId] of activeWorkflows) { + clearPolling(workflowId); } }; node.on("close", () => { - clearPolling(); + clearAllPolling(); }); // Helper to evaluate typedInput properties (supports JSONata) @@ -64,17 +74,19 @@ module.exports = function (RED) { return "grey"; // cancelled, unknown }; - async function fetchStatus(msg, send) { + async function fetchStatus(workflowId) { + const workflow = activeWorkflows.get(workflowId); + if (!workflow) { + return; // Workflow was cleared, stop polling + } + + const { msg, send } = workflow; + try { // Evaluate properties on every poll so that msg overrides can change - const workflowId = await evalProp(node.workflowIdProp, node.workflowIdPropType, msg); const workspaceIdOverride = await evalProp(node.workspaceIdProp, node.workspaceIdPropType, msg); const pollInterval = await evalProp(node.pollIntervalProp, node.pollIntervalPropType, msg); - if (!workflowId) { - throw new Error("workflowId not provided"); - } - const baseUrl = (node.seqeraConfig && node.seqeraConfig.baseUrl) || node.defaultBaseUrl; const workspaceId = workspaceIdOverride || (node.seqeraConfig && node.seqeraConfig.workspaceId) || msg.workspaceId || null; @@ -87,11 +99,14 @@ module.exports = function (RED) { const wfStatus = response.data?.workflow?.status || "unknown"; const statusLower = wfStatus.toLowerCase(); - // Set node status in editor + // Update node status showing count of active workflows + const activeCount = activeWorkflows.size; + const statusText = activeCount > 1 ? `${activeCount} workflows (latest: ${statusLower})` : `${statusLower}`; + node.status({ fill: mapColor(statusLower), shape: /^(submitted|running)$/.test(statusLower) ?
