Hey guys! :grin: do we have mentor for the plugin health project yet ?

halkeye

@DevUt: in an async environment, its usually good practice to not ask yes/no questions, but instead ask questions with details/context.

"Do we have a mentor for the plugin health project yet?"
12 hours later
"no"
12 hours later
"okay i'm interested"

vs
"I'm interested in helping out as a mentor for the plugin health project, is there a mentor yet?"

you saved a bunch of back and forth (just an example, i have no idea why your asking)

Utkarsh Tiwari

@DevUt

Oops I should have cleared my intent, I was just asking because if we have a mentor for that that means the project is an accepted idea right, so that was the sole reason. Apologies!

Hello @DevUt
Yes there are three mentors registered for that project (with one located in France).
I am working on the promotion of the project to "draft" status

I am still working on the PR. It will also give more details about the project itself

I will post here when it is merged

Hi Everyone. Tomorrow is our next GSoC office hours [Asia]. We'll start the meeting by taking questions from GSoC potential participants so come with your questions or add your questions via comments in the gdoc prior to the meeting https://docs.google.com/document/d/1OpvMWpzBKtKnYBAkhtQ1dK5zQix3D7RY5g3vDJXkSnc/edit?usp=sharing

I am interested in the automatic git cache maintenance on the Jenkins controller project from the project idea list. Is there a chat that I can join to discuss this idea because the chat provided on the ideas list does not seem to be working

Hi @aaryan-gautam:matrix.org Thank you for your interest. We'll get that link fixed but you are actually on the correct chat channel here. Feel free to chat away.

I wanted to know the expected length and size of the project whether its 175 hours (medium) or 350 hours (large) and the page also mentions to "implement similar capabilities to manage the cached copies of git repositories" so I wanted to know what it meant by the similar capabilities that could be added and is there a resource/resources that can be suggested to me for learning about the cached copies and if there are some starter bugs that can help me get familiar and get a better understanding for my proposal for this project

Read the documentation for git maintenance from https://git-scm.com/docs/git-maintenance for ideas of the types of problems that can exist for git repositories and that benefit from maintenance tasks. Consider alternatives available to perform similar maintenance tasks on a Jenkins controller or on Jenkins agents. Explore the scheduling alternatives available with Jenkins. Install a Jenkins controller, create a multibranch Pipeline with a GitHub branch source provider and look at the caches created on the Jenkins controller. Consider how the Jenkins controller created those caches and how a maintenance job would find those caches and schedule the maintenance work on those caches. Compare the maintenance task results with command line git and JGit. Are all the maintenance operations feasible in JGit.

@aaryan-gautam:matrix.org Not sure if you've read this quoted message before or not but it might help you by answering some of your questions.

Hi Aaryan Gautam Welcome to the community! Regarding the "Automatic git cache maintenance on the controller" project, there are new newbie issues with links at here. While the standard duration of GSoC is 175 hours, it can be hard to gauge whether more time will be needed as every project will be mentored on a case-by-case basis, as the duration has much to do with the GSoC contributor per se. The project length also depends on the scope and number of features you intend to add to the Jenkins controller. The most important thing to note at the beginning is what "git maintenance" is capable of, so that we could also implement this to Jenkins.

On the official git site it says:

The git maintenance command is designed to simplify the repository maintenance patterns while minimizing user wait time during Git commands. A variety of configuration options are available to allow customizing this process. The default maintenance options focus on operations that complete quickly, even on large repositories.

So this could be a point to keep in mind while developing your own proposal for the project idea.

when I run mvn clean verify on my forked cloned repository then I am failing some of the testcases. I have not made any changes. Could someone guide me why this could be happening? I am using an Intellij as my ide.

I was looking through the issues and I wanted to ask whether this issue is also something that would be addressed with the git cache maintenance on the controller.

Hey! How do I get started with git-plugin. I cloned the repo and ran mvn clean install. How do I use the plugin? Do I need to install jenkins to use the plugin or can I just run the cloned project locally?

Hey Mark! Facing an issue while adding git repo to jenkins. I created a repo on github and added it to an existing jenkin build.

Hey mark! It looks like an "out of memory error". My ram was running at 90%. After terminating the process, my system returned to normal condition.

when I run mvn clean verify on the cloned version, it takes a long time to run the testcases and slows my computer down. What could be the issue? It starts to take 100% cpu and 90% memory and disk

HI @Hrushi20 You could follow up on the issue with a PR and initiate discussion from there, otherwise it would be hard to tell exactly what you mean to do to fix the issue.

You can use the closed PR as a reference.

I am getting the following warning when I try to run mvn clean verify. However, when I try to redirect the -Dfile to Program Files\Java\jdk1.8.0_311\lib\tools.jar, it tells me that the specified file does not exist at the [relative path to]/git/plugin/C:Program. What should I put for -Dfile?

[WARNING] System artifact: com.sun:tools:jar:1.8.0:system has no file attached

Try downloading the file manually from the project website.

Then, install it using the command:
mvn install:install-file -DgroupId=com.sun -DartifactId=tools -Dversion=1.8.0 -Dpackaging=jar -Dfile=/path/to/file

Alternatively, if you host your own repository you can deploy the file there:
mvn deploy:deploy-file -DgroupId=com.sun -DartifactId=tools -Dversion=1.8.0 -Dpackaging=jar -Dfile=/path/to/file -Durl=[url] -DrepositoryId=[id]

Path to dependency:
1) com.sun:tools:jar:1.8.0

com.sun:tools:jar:1.8.0

I get 19 errors from which 17 are caused by test timed out exceptions. One of them is from the job not been triggered. Can anyone suggest me when I can start by looking into these errors? When I run the same clone on gitpod, it works fine passing all the testcases.

I don't think that is a good idea, but what is the stack trace for the errors thrown?

So some parts in the URL pattern can be made optional to satisfy the requirements

@Hrushi20: i'm slowly catching up. With regards to testing. I think the problem is your trying to test the entire problem. One of the good things about testing is to highlight when that happens. You'll find it easier to test if you pull it out into a new class/set of functions, so you don't need to create a full jenkins instance

@halkeye:g4v.dev

Is the intention to find URLs in a string? Or to validate URLs? For the first the stack overflow solutions have kinda been crowd sourced so pretty solid - https://stackoverflow.com/questions/161738/what-is-the-best-regular-expression-to-check-if-a-string-is-a-valid-url

For validating, you should use the url class. It'll be more reliable than anything you come up with
