Handling Chrome Undetected Driver Termination Issue with Driver.Quit() in Selenium

While working with Selenium and Chrome undetected drivers, I encountered an issue where the driver.quit() command was not terminating the Chrome sessions properly due to a bug. This resulted in lingering Chrome processes, which could lead to resource exhaustion and other issues.

To address this problem, I created a batch file named kill.bat with the following content to terminate the Chrome sessions forcibly:

set arg1=%1
taskkill /f /T /pid %arg1%

This batch file uses the taskkill command to forcefully and recursively terminate the process with the given process ID (PID).

Next, I modified my Selenium script to use this batch file for terminating the Chrome sessions. Here is the updated code snippet:

import os
from selenium import webdriver
from undetected_chromedriver.v2 import Chrome, ChromeOptions

# Initialize the Chrome undetected driver
options = ChromeOptions()
driver = Chrome(options=options)

# Perform your Selenium tasks here

# Get the browser process ID
browser_pid = driver.browser_pid

# Terminate the Chrome session using the batch file
os.system(r'kill.bat ' + str(browser_pid))

In this code:

• I import the necessary modules.
• Initialize the Chrome undetected driver with any required options.
• Perform the desired Selenium tasks.
• Retrieve the browser’s process ID (browser_pid).
• Use the os.system() method to execute the kill.bat file, passing the browser_pid as an argument.
  

This approach ensures that the Chrome sessions are terminated cleanly, avoiding any lingering processes and potential resource issues.
