Delete/Modify all Jenkins CI jobs

Navigate to

http://jenkins-ci/script

then, to delete all jobs, run:

for(j in jenkins.model.Jenkins.theInstance.getAllItems()) {
    j.delete() 
}

for(j in jenkins.model.Jenkins.theInstance.getAllItems()) {

j.delete()

}

To filter and disable jobs, run:

for(j in jenkins.model.Jenkins.theInstance.getAllItems()) {
  if(j.name.contains("Chrome")){ 
  	println(j.name);
    j.disabled = true;
  }
}

for(j in jenkins.model.Jenkins.theInstance.getAllItems()) {

if(j.name.contains("Chrome")){

println(j.name);

j.disabled = true;

}

Python Logging Annotation – Automatically create logger for methods

This is a pattern for creating an annotation that will “inject” a logger into a python method. This allows you to decorate a python method with @logged and you will have a variable named logger created with your method name.

This is nice because you do not have to have boilerplate code all over the place. It also allows you to easily have a logger for each function instead of a global logger. This makes reading logs much easier since you can tell exactly where your logging call was made.

Here is an outline of the process, the comments in the code explain where these steps happen:

Get the global variables for the decorated function
If there is an existing logger in the function, we save it
Create a new logger with the function name as the logger name
Set the new logger as a global variable for the function
Call the function
Restore the existing logger as a global

def logged(original_function):
    def lf(*args, **kwargs):
        g = original_function.func_globals # Get globals for function
        oldlogger = g.get('logger') # Save existing logger
        logger = logging.getLogger(original_function.__name__) # Create new logger
        g['logger'] = logger # Set new logger so it is available as 'logger' inside the function
        try:
            return original_function(*args, **kwargs) # Call the function
        finally:
            g['logger'] = oldlogger # Restore the original logger
    return lf

def logged(original_function):

def lf(*args, **kwargs):

g = original_function.func_globals # Get globals for function

oldlogger = g.get('logger') # Save existing logger

logger = logging.getLogger(original_function.__name__) # Create new logger

g['logger'] = logger # Set new logger so it is available as 'logger' inside the function

try:

return original_function(*args, **kwargs) # Call the function

finally:

g['logger'] = oldlogger # Restore the original logger

return lf

Now your methods will look like this:

@logged
def logged_function(param):
    logger.debug("Called logged_function with %s" %(param))
    ...
    return True

@logged

def logged_function(param):

logger.debug("Called logged_function with %s" %(param))

...

return True

Javascript add method to date to select first day of week

Date.prototype.setToFirstDayOfWeek = function(){
    this.setDate(this.getDate() - this.getDay());
    return this;
}

Date.prototype.setToFirstDayOfWeek = function(){

this.setDate(this.getDate() - this.getDay());

return this;

}

Eclipse Luna ‘Build Automatically’ is checked but not working

Eclipse Luna – had “Build Automatically” checked when Eclipse stopped compiling my classes automatically. Finally figured out that the .project file was missing an entry for the javabuilder, so I opened it and added:

<buildCommand>
     <name>org.eclipse.jdt.core.javabuilder</name>
     <arguments>
     </arguments>
</buildCommand>

<name>org.eclipse.jdt.core.javabuilder</name>

</arguments>

</buildCommand>

Then it worked.

DJango Web Servcie

For a web service that is going to be called from an external site, we need to add the CORS headers to make sure the browser will allow it:

def _acao_response(response):
        response['Access-Control-Allow-Origin'] = '*'
        response['Access-Control-Allow-Methods'] = 'GET'

def home_view(request):
	r = { 'response': 'OK', 'data': None }
	response = HttpResponse(json.dumps(r), content_type = "application/json")
        _acao_response(response)
        return response

def _acao_response(response):

response['Access-Control-Allow-Origin'] = '*'

response['Access-Control-Allow-Methods'] = 'GET'

def home_view(request):

r = { 'response': 'OK', 'data': None }

response = HttpResponse(json.dumps(r), content_type = "application/json")

_acao_response(response)

return response

PowerShell Write-Host versus Write-Output

Working with PowerShell, I had a program that was scheduled and was using Write-Host to print messages. This works great if you’re running it in the terminal, but it is not redirectable.

This means that if you schedule it and redirect the output (powershell.exe output-demo.ps1 >out.txt), you get nothing.

However, Write-Host for a comma separated list writes all of the list items on one line. Write-Output puts a newline in between. Take a look at this script:

Write-Host "Hello", "1234"
Write-Output "Hello", "2345"

1 2	Write-Host "Hello", "1234" Write-Output "Hello", "2345"

Here is the output:

Hello 1234
Hello
2345

Hello 1234

Hello

2345

The first line is the Write-Host and the next 2 are from the Write-Output. I don’t know why this is and will update with more information.

C# Process.Start with hidden terminal window

Having issues getting the System.Disagnostics.Process.Start(…) method to run a process and hide the window. I tried all sorts of things including:

String proc = "d:\\php-5.6.8\\php-cgi.exe";
String args = "-b localhost:9000";ProcessStartInfo psi = new ProcessStartInfo();

psi.WindowStyle = ProcessWindowStyle.Hidden;
psi.RedirectStandardOutput = true;
psi.RedirectStandardError = true;
psi.UseShellExecute = false;
psi.CreateNoWindow = true;

p = new Process();
p.StartInfo = psi;
p = Process.Start(proc, args);

String proc = "d:\\php-5.6.8\\php-cgi.exe";

String args = "-b localhost:9000";ProcessStartInfo psi = new ProcessStartInfo();

psi.WindowStyle = ProcessWindowStyle.Hidden;

psi.RedirectStandardOutput = true;

psi.RedirectStandardError = true;

psi.UseShellExecute = false;

psi.CreateNoWindow = true;

p = new Process();

p.StartInfo = psi;

p = Process.Start(proc, args);

Finally came across this page on the msdn site that says:

If the UseShellExecute property is true or the UserName and Password properties are not Nothing, the CreateNoWindow property value is ignored and a new window is created.

I’m using the method:

Start(String command, String arguments)

However, there is another method that is:

Start(String command, String arguments, String user, SecureString password, String domain)

So, if we change the last line from:

p = Process.Start(proc, args);

to:

p = Process.Start(proc, args, null, null, null);

it works! Here is the complete code listing:

class Program
	{
		Process p;
		String proc = "d:\\php-5.6.8\\php-cgi.exe";
		String args = "-b localhost:9000";
		
		public Program(){
		}
		
		public void RunProgram(){
			Console.Write("Running: " + proc);
			
			ProcessStartInfo psi = new ProcessStartInfo();
			psi.WindowStyle = ProcessWindowStyle.Hidden;
			psi.RedirectStandardOutput = true;
			psi.RedirectStandardError = true;
			psi.UseShellExecute = false;
			psi.CreateNoWindow = true;
			
			p = new Process();
			p.StartInfo = psi;
			p = Process.Start(proc, args, null, null, null);
			
			Console.Write("Process started...");
		}
		
		public void Terminate(){
			p.Kill();
			p.Close();
			p.Dispose();
		}
		
		public static void Main(string[] args)
		{
			Console.WriteLine("Hello World!");
			
			Program myp = new Program();
			myp.RunProgram();
			
			Console.Write("Press any key to continue . . . ");
			Console.ReadKey(true);
			myp.Terminate();
		}
	}
