Chromedriver not deleting scoped* dir in temp fold

Question

With latest chromedriver.exe running into out of disk space issues as chromedriver is not deleting the folder named scoped_* at the end of the execution. It is occupying almost 20 GB of space for 400 tests. I tried with both 2.28 and 2.29 versions of chromedriver. I am exiting the driver properly with driver.close() and driver.Quit() too. Chrome browser version is 57.

Answer 1

was reported and fixed. Checkout 2.30 or 2.31

UPD. at least works for our grid. If you still have issues it's better you report in into any scope_dir thread on productforums.google.com In addition before it was fixed we used PS script that cleared all files in ..*\AppData\Local\Temp

UPD. check out the chrome browser has completed update process. Along with this fix we had an issue that browser keep in state "restart required for update to complete" even after restart. It's maybe both browser and driver are to be updated for fix to work- can not say for sure.

UPD2. I see some people still have the issue. (maybe they re-released it?) Here the sample of a PS script that was used on Win machine at the time we had the issue. Cleaner.ps1

#infinite loop for calling  function   
$ScriptPath = $MyInvocation.MyCommand.Definition

# 2030 year error
$timeout = new-timespan -end (get-date -year 2030 -month 1 -day 1)
$sw = [diagnostics.stopwatch]::StartNew()
while ($sw.elapsed -lt $timeout){
    if (-Not (test-path  $ScriptPath)){
        write-host "v been renamed, quiting!"
        return
        }

    start-sleep -seconds 60
    # logic
$time=Get-Date
$maxdate = $time.AddMinutes(-120)
Get-WmiObject -Class Win32_UserProfile  | Foreach-Object {
    $path =  $_.LocalPath 
    if (-Not $path.Contains('Windows')){
    echo $path
    $Files = Get-ChildItem "$($path)\..\*\AppData\Local\Temp" -recurse | ?  {$_.LastWriteTime -lt $maxdate } |
     remove-item -force -recurse
    echo $Files 

    }
}   
}

run.bat

#PowerShell -Command "Set-ExecutionPolicy Unrestricted" >> "%TEMP%\StartupLog.txt" 2>&1

Answer 2

I managed this by adding deletion of temp folders that begins with "scoped_dir" after quitting driver like:

 public static void teardown_()
        {
            // quit driver
            if (driver != null)
                driver.Quit();

            // delete all "scoped_dir" temp folders 
            string tempfolder = System.IO.Path.GetTempPath();
            string[] tempfiles = Directory.GetDirectories(tempfolder, "scoped_dir*", SearchOption.AllDirectories);
            foreach (string tempfile in tempfiles)
            {
                try
                {
                    System.IO.DirectoryInfo directory = new System.IO.DirectoryInfo(tempfolder);
                    foreach (System.IO.DirectoryInfo subDirectory in directory.GetDirectories()) subDirectory.Delete(true);
                }
                catch (Exception ex)
                {
                    writeEx("File '" + tempfile + "' could not be deleted:\r\n" +
                            "Exception: " + ex.Message + ".");
                }
            }
        } 

Hope it helps!

This is a known bug that will be fixed with Chromedriver 2.30 https://bugs.chromium.org/p/chromedriver/issues/detail?id=644

This appears to be a race condition between ChromeDriver and Chrome. ChromeDriver creates these temp directories for use by Chrome, and at the end ChromeDriver tries to delete those directories. ChromeDriver waits for the main Chrome process to terminate before doing the deletion, but some Chrome child processes might still be running and holding on to those directories, causing the deletion to fail. Currently ChromeDriver doesn't retry the deletion.

Deleting the temp files like Daniel mentioned can be a temporary solution but I would remove it as soon as Chromedriver 2.30 is released.

Update

Chromedriver 2.30 is out and should fix this issue.

Using latest chromedriver 2.30.1 didn't solve the issue for me - I kept running out of storage in my %TEMP% directory when running parallel selenium jobs.

The best solution is to control the userDataDir via Chrome Options and dispose of the directory yourself after you driver.quit()

If your process is synchronous than @cdzar's solution above will work, but for parallel jobs you really need to control the directory create/dispose yourself.
