How to get (more) involved with Masakari

So you want to get more involved with Masakari? Or you are new to Masakari and wondering where to start?

We are working on building easy ways for you to get help and ideas on how to learn more about Masakari and how the Masakari community works.

How do I get started?

There are quite a few global docs on this:

There is more general info, non Masakari specific info here:

What should I work on?

So you are starting out your Masakari journey, where is a good place to start?

If you’d like to learn how Masakari works before changing anything (good idea!), we recommend looking for reviews with -1s and -2s and seeing why they got down voted. Once you have some understanding, start reviewing patches. It’s OK to ask people to explain things you don’t understand. It’s also OK to see some potential problems but put a +0.

Once you’re ready to write code, take a look at some of the work already marked as low-hanging fruit:

How do I get my feature in?

The best way of getting your feature in is… well it depends.

First concentrate on solving your problem and/or use case, don’t fixate on getting the code you have working merged. It’s likely things will need significant re-work after you discuss how your needs match up with all the existing ways Masakari is currently being used. The good news, is this process should leave you with a feature that’s more flexible and doesn’t lock you into your current way of thinking.

A key part of getting code merged, is helping with reviewing other people’s code. Great reviews of others code will help free up more core reviewer time to look at your own patches. In addition, you will understand how the review is thinking when they review your code.

Also, work out if any ongoing efforts are blocking your feature and helping out speeding those up. The spec review process should help with this effort.

Top Tips for working with the Masakari community

Here are some top tips around engaging with the Masakari community:

  • IRC

    • we talk a lot in #openstack-masakari

    • do ask us questions in there, and we will try to help you

    • not sure about asking questions? feel free to listen in around other people’s questions

    • we recommend you setup an IRC bouncer: https://wiki.openstack.org/wiki/IRC

  • Email

    • Use the [masakari] tag in the mailing lists

    • Filtering on [masakari] and [all] can help tame the list

  • Be Open

    • i.e. don’t review your teams code in private, do it publicly in gerrit

    • i.e. be ready to talk about openly about problems you are having, not “theoretical” issues

    • that way you can start to gain the trust of the wider community

  • Got a problem? Please ask!

    • Please raise any problems and ask questions early

    • we want to help you before you are frustrated or annoyed

    • unsure who to ask? Just ask in IRC.

  • Talk about problems first, then solutions

    • Don’t think about “merging your patch”, instead think about “solving your problem”

    • conversations are more productive that way

  • It’s not the decision that’s important, it’s the reason behind it that’s important

    • Don’t like the way the community is going?

    • Please ask why we were going that way, and please engage with the debate

    • If you don’t, we are unable to learn from what you have to offer

  • No one will decide, this is stuck, who can help me?

    • it’s rare, but it happens

    • …but if you don’t ask, it’s hard for them to help you

Process

It can feel like you are faced with a wall of process. We are a big community, to make sure the right communication happens, we do use a minimal amount of process.

If you find something that doesn’t make sense, please:

  • ask questions to find out *why* it happens

  • if you know of a better way to do it, please speak up

  • one “better way” might be to remove the process if it no longer helps

Why bother with any process?

Why is it worth creating a bug or blueprint to track your code review? This may seem like silly process, but there is usually a good reason behind it.

We have lots of code to review, and we have tools to try and get to really important code reviews first. If yours is really important, but not picked up by our tools, it’s possible you just get lost in the bottom of a big queue.

If you have a bug fix, you have done loads of work to identify the issue, and test out your fix, and submit it. By adding a bug report, you are making it easier for other folks who hit the same problem to find your work, possibly saving them the hours of pain you went through. With any luck that gives all those people the time to fix different bugs, all that might have affected you, if you had not given them the time go fix it.

It’s similar with blueprints. You have worked out how to scratch your itch, lets tell others about that great new feature you have added, so they can use that. Also, it stops someone with a similar idea going through all the pain of creating a feature only to find you already have that feature ready and up for review, or merged into the latest release.

Hopefully this gives you an idea why we have applied a small layer of process to what we are doing. Having said all this, we need to unlearn old habits to move forward, there may be better ways to do things, and we are open to trying them. Please help be part of the solution.

Why do code reviews if I am not in masakari-core?

Code reviews are the life blood of the developer community.

There is a good discussion on how you do good reviews, and how anyone can be a reviewer: http://docs.openstack.org/infra/manual/developers.html#peer-review

In the draft process guide, I discuss how doing reviews can help get your code merged faster: Masakari team process.

Let’s look at some of the top reasons why participating with code reviews really helps you:

  • Doing more reviews, and seeing what other reviewers notice, will help you better understand what is expected of code that gets merged into master

  • Having more non-core people do great reviews, leaves less review work for the core reviewers to do, so we are able get more code merged

  • Empathy is one of the keys to a happy community. If you are used to doing code reviews, you will better understand the comments you get when people review your code. As you do more code reviews, and see what others notice, you will get a better idea of what people are looking for when then apply a +2 to your code.

What are the most useful types of code review comments? Well here are a few to the top ones:

  • Fundamental flaws are the biggest thing to spot. Does the patch break a whole set of existing users, or an existing feature?

  • Consistency of behavior is really important. Does this bit of code do things differently to where similar things happen elsewhere in Masakari?

  • Is the code easy to maintain, well tested and easy to read? Code is read order of magnitude times more than it is written, so optimize for the reader of the code, not the writer.

Let’s look at some problems people hit when starting out doing code reviews:

  • My +1 doesn’t mean anything, why should I bother?

    • So your +1 really does help. Some really useful -1 votes that lead to a +1 vote helps get code into a position

  • When to use -1 vs 0 vs +1

  • I have already reviewed this code internally, no point in adding a +1 externally?

    • Please talk to your company about doing all code reviews in the public, that is a much better way to get involved. Showing how the code has evolved upstream, is much better than trying to ‘perfect’ code internally, before uploading for public review. You can use Draft mode, and mark things as WIP if you prefer, but please do the reviews upstream.

  • Where do I start? What should I review?

How do I become masakari-core?

You don’t have to be masakari-core to be a valued member of the Masakari community. There are many, many ways you can help. Every quality review that helps someone get their patch closer to being ready to merge helps everyone get their code merged faster.

The first step to becoming masakari-core is learning how to be an active member of the Masakari community, including learning how to do great code reviews.

If you feel like you have the time to commit to all the masakari-core membership expectations, reach out to the Masakari PTL who will be able to find you an existing member of masakari-core to help mentor you. If all goes well, and you seem like a good candidate, your mentor will contact the rest of the masakari-core team to ask them to start looking at your reviews, so they are able to vote for you, if you get nominated for join masakari-core.

We encourage all mentoring, where possible, to occur on #openstack-masakari so everyone can learn and benefit from your discussions.

The above mentoring is available to everyone who wants to learn how to better code reviews, even if you don’t ever want to commit to becoming masakari-core. If you already have a mentor, that’s great, the process is only there for folks who are still trying to find a mentor. Being admitted to the mentoring program no way guarantees you will become a member of masakari-core eventually, it’s here to help you improve, and help you have the sort of involvement and conversations that can lead to becoming a member of masakari-core.

Note

You can try using masakari-ptl and/or masakari-core in your IRC message to get a response from the desired people.
