From 42ccc3c0183ebabaaeb5294f6de820f80103ef28 Mon Sep 17 00:00:00 2001 From: Rafael Araujo Lehmkuhl Date: Fri, 22 Nov 2024 13:26:42 -0300 Subject: [PATCH] vehicle-discovery: Fix implementation to allow finding IPs generated by a DHCP server in the vehicle The vehicle usually has some IPs generated by it's own servers (e.g.: 192.168.3.1 for USB C connections), which offers a dynamic IP for the topside computer. With this change, those IPs are also findable. This commit should be in the original PR, but got lost on the rebase process. --- electron/preload.ts | 2 +- electron/services/network.ts | 50 ++++++++------ src/components/VehicleDiscoveryDialog.vue | 8 ++- src/libs/cosmos.ts | 4 +- src/libs/electron/vehicle-discovery.ts | 84 ++++++++++------------- src/types/network.ts | 21 ++++++ 6 files changed, 96 insertions(+), 73 deletions(-) create mode 100644 src/types/network.ts diff --git a/electron/preload.ts b/electron/preload.ts index bfdd3fe8c..4312004c1 100644 --- a/electron/preload.ts +++ b/electron/preload.ts @@ -1,5 +1,5 @@ import { contextBridge, ipcRenderer } from 'electron' contextBridge.exposeInMainWorld('electronAPI', { - getNetworkInfo: () => ipcRenderer.invoke('get-network-info'), + getInfoOnSubnets: () => ipcRenderer.invoke('get-info-on-subnets'), }) diff --git a/electron/services/network.ts b/electron/services/network.ts index 991b0f60f..4f56dbbf4 100644 --- a/electron/services/network.ts +++ b/electron/services/network.ts @@ -1,39 +1,45 @@ import { ipcMain } from 'electron' import { networkInterfaces } from 'os' -/** - * Information about the network - */ -interface NetworkInfo { - /** - * The subnet of the local machine - */ - subnet: string -} - +import { NetworkInfo } from '../../src/types/network' /** * Get the network information * @returns {NetworkInfo} The network information */ -const getNetworkInfo = (): NetworkInfo => { - const nets = networkInterfaces() +const getInfoOnSubnets = (): NetworkInfo[] => { + const allSubnets = networkInterfaces() - for (const name of Object.keys(nets)) { - for (const net of nets[name] ??
