From 490aa1a2ebda38a4e1fa3a666ba1980eef983b63 Mon Sep 17 00:00:00 2001 From: drono Date: Tue, 13 May 2025 12:28:56 +0300 Subject: [PATCH 1/3] fix: resolve HTTP request timeouts and connection issues This commit addresses several critical issues in the OpenHIM routing system: 1. Fixed socket hangup errors by creating fresh connection agents for each request 2. Resolved timeout issues by extending server socket timeouts and improving promise handling 3. Added support for Brotli compression to handle all content encoding types 4. Implemented robust error handling for secondary routes to prevent transaction failures 5. Fixed duplicate requests by removing problematic await statements and properly chaining promises 6. Added comprehensive logging for better diagnostics and troubleshooting 7. Improved secondary route processing to ensure transactions complete even when routes fail These changes significantly improve the reliability of the routing system, particularly for secondary routes that depend on primary route responses. --- src/middleware/router.js | 321 +++++++++++++++++++++++++++++---------- 1 file changed, 237 insertions(+), 84 deletions(-) diff --git a/src/middleware/router.js b/src/middleware/router.js index 944897e3..439fb5f5 100644 --- a/src/middleware/router.js +++ b/src/middleware/router.js @@ -243,31 +243,49 @@ function matchCodeOfPrimaryResponse(ctx, route) { function storingNonPrimaryRouteResp(ctx, route, options, path) { try { if ((route != null ? route.name : undefined) == null) { - route = {name: route.name} + route = {name: route.name || 'unknown'} } if ((route != null ? route.response : undefined) == null) { route.response = { status: 500, - timestamp: ctx.requestTimestamp + timestamp: ctx.requestTimestamp || new Date(), + headers: {}, + body: 'No response available' } } if ((route != null ? route.request : undefined) == null) { route.request = { - host: options.hostname, - port: options.port, - path, - headers: ctx.request.header, - querystring: ctx.request.querystring, - method: ctx.request.method, - timestamp: ctx.requestTimestamp + host: options.hostname || 'unknown', + port: options.port || 0, + path: path || 'unknown', + headers: ctx.request ? ctx.request.header : {}, + querystring: ctx.request ? ctx.request.querystring : '', + method: ctx.request ? ctx.request.method : 'GET', + timestamp: ctx.requestTimestamp || new Date() } } + // Ensure the route is in ctx.routes + if (!ctx.routes) { + ctx.routes = [] + } + + // Check if this route is already in ctx.routes + const existingRouteIndex = ctx.routes.findIndex(r => r.name === route.name) + if (existingRouteIndex >= 0) { + // Update existing route + ctx.routes[existingRouteIndex] = route + } else { + // Add new route + ctx.routes.push(route) + } + return messageStore.storeNonPrimaryResponse(ctx, route, () => {}) } catch (err) { - return logger.error(err) + logger.error(`Error in storingNonPrimaryRouteResp: ${err.message}`) + return Promise.resolve() // Don't let this error propagate } } @@ -276,6 +294,11 @@ function sendRequestToRoutes(ctx, routes, next) { secondaryPromises = [] let promise = {} ctx.timer = new Date() + + // Initialize ctx.routes array to store all route responses + if (!ctx.routes) { + ctx.routes = [] + } if (containsMultiplePrimaries(routes)) { return next( @@ -350,6 +373,11 @@ function sendRequestToRoutes(ctx, routes, next) { path ).then(routeObj => { logger.info(`Storing non primary route responses ${route.name}`) + + // Ensure the route is added to ctx.routes + if (!ctx.routes.some(r => r.name === routeObj.name)) { + ctx.routes.push(routeObj) + } return storingNonPrimaryRouteResp(ctx, routeObj, options, path) }) @@ -369,82 +397,140 @@ function sendRequestToRoutes(ctx, routes, next) { logger.info(`executing non primary: ${route.name}`) if (route.waitPrimaryResponse && matchCodeOfPrimaryResponse(ctx, route)) { - promise = buildNonPrimarySendRequestPromise( - ctx, - route, - options, - path - ).then(routeObj => { - logger.info(`Storing non primary route responses ${route.name}`) - - return storingNonPrimaryRouteResp(ctx, routeObj, options, path) - }) - - secondaryPromises.push(promise) + console.log(`Processing secondary route: ${route.name}`) + + // Create a wrapped promise that won't reject + const safePromise = new Promise(resolve => { + // Create a new agent for each request to avoid connection pooling issues + const newOptions = {...options};
