SeGrid+Chromedriver = Always Starts with Logging Enabled #485

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Platform: Ubuntu/EC2
chromedriver: 2.1
Chrome Version: Google Chrome 28.0.1500.71
Selenium version: 2.33.0 (selenium-server-standalone)

What steps will reproduce the problem?
1. Create Script calling chromedriver (all of our Selenium scripts are Python)
2. Add "--disable-logging" as an option
3. Execute the test

I expect to see the browser started without the "--enable-logging and 
--log-level=1".
Instead, I see the full set of startup flags with "--disable-logging" at the 
front.  It appears that this is being overriden by the succeeding 
"--enable-logging" flag.

I suppose there are some usecases where this would be of value, but we are 
experiencing system slow downs that appear to be attributable - in part - to 
this extra logging.

Below: 
-'ps -ef' output to show everything going on
- bugtest.py to recreate

Additionally, looking at the ps output, it may be just related to the logging, 
but there are a number of processes spawned that don't seem to be relevant to 
using Chrome as a validation tool, but rather these seem to be related to 
testing Chrome itself.  Any clarification on this point would be appreciated.

We can use excludeSwitches with ChromeOptions as in sample code:

Sample Code:
ChromeOptions options = new ChromeOptions();
options.addArguments("--disable-logging");
options.setExperimentalOption("excludeSwitches", 
Arrays.asList("enable-logging","log-level"));

DesiredCapabilities capabilities = DesiredCapabilities.chrome();
capabilities.setCapability(ChromeOptions.CAPABILITY, options);

WebDriver driver = new RemoteWebDriver(new URL(
"http://localhost:4444/wd/hub"), capabilities);
driver.get("http://google.com");
Thread.sleep(1000);
long navigationStart = (long) 
((JavascriptExecutor)driver).executeScript("return 
performance.timing.navigationStart");
long responseStart = (long) ((JavascriptExecutor)driver).executeScript("return 
performance.timing.responseStart");

System.out.format("%d - %d = %d", navigationStart,responseStart, 
responseStart-navigationStart);

Please try as in sample code and let us know if we differ from what you are 
doing
