Jenkins console script with power

Problem

Many times I have been on a jenkins script console wanting to do a shell script using the pipe character to chain calls together.

du -sh --max-depth=1 | sort -h

Jenkins Script console default scripting

The suggested way of doing things leaves much to be desired.  It does give you groovy to do queries in but it is not very powerful.

println "uname -a".execute().text

The Good

Works for default simple single commands.

The Bad

You cannot pipe a command to another and white space in directory names does not work.

Step better

println(['ls', '/tmp/folder with spaces'].execute().text)

The Good

This to allow folders with spaces by turning command into array of strings. You do not have to escape any spaces and it will be able to deal with it.

The Bad

You cannot chain commands together

The better Jenkins script console command

Source of Jenkins shell with pipe discussion

println new ProcessBuilder( 'sh', '-c', 'du -h --max-depth=1 /var/foo/bar/ | sort -hr').redirectErrorStream(true).start().text

The good

Can chain commands together

The Bad

Have to escape whitespace in the java way with \\

println new ProcessBuilder( 'sh', '-c', 'du -h --max-depth=1 /var/foo/bar/folder\\ with\\ spaces | sort -hr').redirectErrorStream(true).start().text

Unit testing $scope.$on(‘$viewContentLoaded’) on an Angularjs Controller

TL;DR = call

$scope.$broadcast('$viewContentLoaded');

in your unit test. This will call your

$scope.$on('$viewContentLoaded', function () {}); 

method in your controller

If you have a Controller that has a method that is not fired until the view is loaded you will have a method similar to the following:

    $scope.$on('$viewContentLoaded', function () {
       SomeService.callMethod(params);
    });

The test case needs to wire in the $scope into your test like below

describe('when the campaign controller is initialized', function () {

 beforeEach( function() {
    $scope.$broadcast('$viewContentLoaded');
 } );

 it('should call the getAllCampaignTypes service call', function () {
     expect(mockedSomeService.callMethods).toHaveBeenCalledWith( ... );
 });

The Most important thing is the call to $scope.$broadcast(‘$viewContentLoaded’);

Yeoman grunt-ngmin to grunt-ng-annotate save massive time on your grunt build.

Background

If you have build your skeleton app from yeoman using the angularjs-generator and you created it before August 3rd 2014  you are running ngmin task.

Ngmin has been deprecated and you are told this every time you do an npm install on the project.

Git Issue that resolves this for new generated projects from yeoman

https://github.com/yeoman/generator-angular/issues/801

Why to migrate.

ng-min is deprecated so it is no longer supported.

ng-min is slow.  For a mature medium-sized angularjs app ng-min was taking 50 seconds of the build time.  Running with ng-annotate instead it now takes only 2 seconds to do the same thing.

Now the uglify task takes the most time of the build at 8 seconds against the 2 seconds needed for the ngannotate task.

A savings of 48 seconds a build.  

Built Machine spec:

OSX 10.9.5 with 3.2 GHz with 24 GB of ram.  No modifications have been made to the memory settings for grunt or node.

Jenkins Fixing SCM Sync with Git and Failing with Delete Jobs

https://wiki.jenkins-ci.org/display/JENKINS/SCM+Sync+configuration+plugin

I have encountered this several times where if you try and change a job name along with any configuration for a job Git will get into a bad state and the SCM will start throwing up errors like:

delete Jobs/OLD_JOB_NAME 

The only thing I have found is to fix this is to follow the following steps:

You will have to have admin rights and the ability to restart your jenkins.

1. recreate the OLD_JOB_NAME
2. change the system configuration scm sync to none.
3. restart the jenkins.  via your_jenkins_server/restart
4. 1. change the system configuration scm sync to git.
5. Ensure that the configuration is now syncing correctly  and you do not have any more errors.
6. delete OLD_JOB_NAME again.
7. If this still does not work you can try downgrading the plugin and repeating the steps again.

Warning:

You may lose all your job configurations after you reenable the SCM sync so you will have to make a small change to each job name such as changing the description by a single letter.

 

 

Saving csv files from a Nodejs project

Update: package available on bower.  bower -S FileSaver.

I am requesting a csv from another service and I wanted to be able to prompt the customer to save the csv for use later.  I managed to get it to save the csv but the filename could not be set so it was not useful.  I found the following library to help out with this.

Angularjs Custom Form Validation

update: 9/9/14 added the ng-learn link which has  a flushed out example. If you are doing this you will need to change you test cases and include all the things like you were testing a directive.

If you want to set an input value to be invalid before submission then this is a good resource.

$scope.yourForm.nameOfElement.$setValidity( ‘reason’,  false );

E.G.: You want to add an error to your start date in a search form.

$scope.searchForm.startDate.$setValidity( ‘date’, false );

Click the launch demo button.  Then click the script.js and the spec.js to see the full example.

IE8 Angularjs

I had a problem with IE8 compatibility mode going to document Mode: IE 7 standards. This caused my javascript to act funny and radio buttons not to work.
I was also getting the error pop up too:
