How to implement progressiveHtml kind of an approach

[Ravi Teja Lokineni]

Hi,

I wasn't able to figure out what Jenkins is doing(for achieving the progressive html of the console logs) by looking at the code. Could someone please give me an overview of how it's implemented. I would like to use a similar approach in one of my projects I'm involved in.

Hi Ravi,

 

if you use the network tab in firebug/firefox while you see a progressing log output of a running job, you will often find something like

 

http://<jenkins url>/job/<job name>/<build nr>/logText/progrssiveHtml

 

This leads to the file /core/src/main/resources/hudson/model/Run/console.jelly and /core/src/main/resources/lib/hudson/progressiveText.jelly of the jenkins-core maven module, where this link is used in the progressiveText tag. The implementation can be found in /core/src/main/java/hudson/model/LargeText.java in the method doProgressiveText.

 

In short, its an AJAX request called every x seconds adding more console output to the <pre id="out">-html element.

 

Hope this helps.

 

Regards,

 

Frederik
