a day in sheriffing

July 3rd, 2015 by cbook

Hi,

since i talked with a lot of people about Sheriffing and what we do here is what a typical day for me look:

We care about the Code Trees like Test Failures etc

I usually start the day with checkin the trees we are responsible forΒ  for test failures using treeherder. This gives me first a overview of the current status and as well make sure that everything is ok for the Asian and European Community which is online at that time.

This Tasks is ongoing till the end of my duty shift. From time to time this means we have to do backouts for code/test regressions.
Beside this i do stuff like checkin-neededs, uplifts etc and other tasks and of course always availble for questions etc on irc πŸ™‚

Also i was thinking about some parts of my day-to-day experience:

Backouts and Tree Closures:

While backouts of code for test failures/bustages etc is one important task of sheriffs (and the managing of tree closures related to this), its always a mixed feeling to backout work from someone (and no one wants to cause a bustage) but its important to ensure quality of our products.

Try Server!!!

Tree Closures due to backouts can have the side effect that others are blocked with checkins. So if in doubt if your patch compile or could cause test regressions, please consider a try run, this helps at lot to keep tree closures for code issues at a minimum.

And last but not least Sheriffing is a Community Task! So if you want to be part of the Sheriff Team as Community Sheriff please sent me a mail at tomcat at mozilla dot com

Thanks!

Results of the Sheriff Survey

April 1st, 2015 by cbook

Hi,

we closed our Sheriff Survey on Monday and i wanted to share some highlights from the Results. Thanks for taking part in the Survey!

1.Communication with the Sheriffs

We got very good and positive Feedback about the Interaction/Communication with the Sheriffs. We know that backouts are never a good/positive thing and we sheriffs assume always the best intentions – nobody _wants_ to cause bustage, but it happens.

We also noticed a lot of comments of checkin-needed requestors and the hope we have at some time the autolander system (that lands patches automatically). There is work being done on this like as example in https://bugzilla.mozilla.org/show_bug.cgi?id=1128039

 

2. Trychooser and other Feedback

We got comments about trychooser and how this could be improved. That Feedback is very valuable and we will pass that Feedback over to the Releng Folks. For all Feedback and Suggestions we are looking at the survey what we can improve and realize. As example one result is now https://bugzilla.mozilla.org/show_bug.cgi?id=1145836 πŸ™‚

 

3. Getting Involved!

We got several Community Member with interest in helping out with Sheriffing! Thats really great and we will follow-up here soon. Also its not too late to get involved. Just drop me or the sheriff lists (sheriffs@mozilla.org) a note!

 

4. You can reach us at anytime!

While the Survey is closed now you can still contact us anytime for feedback, questions and when you want to be involved! Just drop us a note at sheriffs@mozilla.org or ping the Sheriff on duty (normally the one with the |sheriffduty tag in #developers on irc.mozilla.org).

Thanks!

First overview from the sheriff survey!

March 24th, 2015 by cbook

Hi,

thanks for all the Reply’s we got for the Sheriff Survey! If you haven’t already took part in it, its still online and you can still take part in the survey!

While we close the Survey in a few days and i will provide a comprehensive overview of course, i was feeling i could already do some quick overview what we got so far.

One big take away is how important checkin-needed requests is and how many people depend on this. We are very sorry if there are delays with picking up checkin-needed requests but since its a human task it depend how much is ongoing with the trees etc.

But there is work being done on Autoland like on https://wiki.mozilla.org/Auto-tools/Projects/Autoland πŸ™‚

Also to follow up on 2 concrete things (you might know or maybe not).

Question: How do i know why the tree is closed (when we have a tree closure) on Treeherder

Answer:Β  Just hover over the repo name in Treeherder (as example mozilla-inbound) or click on the info button right next to the repo name

Question: When i land something on like mozilla-inbound its a mess to manually copy and past the hg changeset url to bug

Answer: We have a tool called mcmerge its right next to every push in the drown-down arrow action menu and unlike the name says its not just to mark merges. During the survey we found out that the name is misleading so we trying to find a new name – https://bugzilla.mozilla.org/show_bug.cgi?id=1145836

Thanks,

Please take part in the Sheriff Survey

March 17th, 2015 by cbook

Hi,

When we moved to the “inbound” model of tree management, the Tree Sheriffs became a crucial part of our engineering infrastructure. The primary responsibility of the Sheriffs is and will always be to aid developers to easily, quickly, and seamlessly land their code in the proper location(s) and ensure that code does not break our automated tests. In the service of this objective, the Sheriffs work closely with the larger engineering organization to create and enforce landing policies that increase productivity while maintaining an efficient and robust automated testing system. Beyond the policy role, they have also become shepherds of automation quality by monitoring intermittent failures, performing uplifts and merges, and identifying poorly performing automation machines. This role has proven successful, and so a formal module for the Tree Sheriffs in the larger context of the Activities Module was created.

But of course there is always room for improvements and ideas how we can make things better. In order to get a picture from our Community how things went and how we can improve our day-to day-work.

So we created the Sheriff Survey here -> http://goo.gl/forms/kRXZDtSjSj
Thanks for taking part in that!

The past, Current and future

October 10th, 2014 by cbook

– The past –
I’m now about a year member of the A-Team (Automation and Tools Team) and also Fulltime Sheriff.

It was the end of a lot of changes personal and job wise. I moved from the Alps to the Munich Area to the City of Freising and (and NO i was not at the Beer Oktoberfest πŸ˜‰ and working as Fulltime Sheriff after my QA/Partner Build and Releng Duties.

Its awesome to be part of the Sheriff Team and was also awesome to get so much help from the Team like from Ed, Wes and Ryan to get started.

At one time i took over the Sheriff-Duty for my European Timezone and it was quite challenging having the responsible for all the Code Trees with Backouts etc and also later checkin-neededs πŸ™‚ What i really like as Sheriff is the work across the different Divisions at Mozilla and its exciting to work as Mozilla Sheriff too πŸ™‚

One of main contribution beside getting started was helping creating some How-To Articles at https://wiki.mozilla.org/Sheriffing/How:To . I hope that will help also others to get involved into sheriffing.

– Current –

We just switched over to use Treeherder as new tool for Sheriffing.

Its quite new and so it feels (as everything like a new car there are this questions like how i do things i used to do in my old car etc) and there are still some bugs and things we can improve but we will get there. Also its a ideal time for getting involved into sheriffing like with hammering on Treeherder.

and that leads into ….:)

– The Future is You – !

As every Open Source Project Mozilla is heavily depended on Community Members like you and there is even the oppourtunity beside all the other Areas at Mozilla to work as Community Sheriff.So let us know if you want to be involved as Community-Sheriff. You are always welcome. You can find us in the #ateam Channel on irc.mozilla.org

For myself i’m planning to work beside my other tasks more in Community Building like blogging about Sheriffing and also taking more part in the Open Source Meetings in Munich.

Getting started in the Community… -> Today! :)

October 21st, 2013 by cbook

Hey,

i’m now over 10 Years a Mozillian and Part of the Mozilla Community (and now about over 6 years employee at Mozilla) and it still rocks.

I’m sure everyone involved into Mozilla has his own story how he/she got involved and here i my story:

How i got involved:

First, i never actively planned to join the Mozilla Community it just happened πŸ™‚ I worked back in 2001 at a German Email Provider as 2nd Level Support Engineer and as part of my Job (and also to Support Customers) we used different Email Programm’s to find out how to set-up the Programm and so.

Some Friends already involved into OpenSource (the Linux Community) pointed me to this Mozilla Programm (at that time M1 or so) and i liked the Idea with this “Nightly”. Having everyday a brand new Program was something really cool and so started my way into the Community without even knowing that i’m now Part of the Community.

So over the years with Mozilla i finally filed my first bug and and was scared like hell (all this new fields in a non-native language) and not really knowing what i signed up when i clicked up this “submit” button in bugzillla πŸ™‚ (was not even sure if i’m NOW supposed to fix the bug πŸ™‚

So over the years with more involved into Mozilla and (in my case) with QA and Testing i got the offer to work at my favorite OpenSource Project and Browser in Full-time. And still super excited to work as part of this super great team.

And its still great to show new Community Members how to got involved

What i learned

Being a Community Member at Mozilla is something very special. Even from the first more active days in the QA Community i felt more than welcome and people are very thankful and helpful to show you the way and how stuff works.

I was never planning or hoping to get rewards etc when getting started, but contributing to a OpenSource Project like Mozilla is no one-way thing where you donate something to the Project. You get a lot back like interacting with a lot of people from different locations and maybe from around the world.

Also i learned a lot about Software Engineering like how stuff works and also about Teamwork and Co-working and also somehow improved my language skills a lot πŸ™‚ Also you meet and work at least online with a lot of new friends. Thats all something you never get at one place in your normal day job (at least was my experience)

Lessons learned.

The most important lesson i learned over the years is “never afraid to ask questions”. Nobody is expecting you that you know everything. So never afraid to ask questions – its much better to ask someone instead of getting stuck on something where the answer might be a “mouse-click away” on IRC πŸ™‚ Also this might also result in new insights into the Problem and Solution and maybe result in a way better solution than you were thinking.

Learn to accept that there will be mistakes – nobody is perfect – and there might be situations where you are on the wrong track or you made an error/ mistake. Happened as example to me too when i was verifying a bug wrongly in a Firefox Release that caused in the End a Re-Release of a Firefox Version. I can tell you i was super sad that day when i realized that i could have catched the Regression if i were digging deeper and with more testing etc…So yeah was a super bad feeling but then someone i got of motivation from other Team Members telling me that Errors can happen and thats its not the end of the world. So yeah that was super great at that day and reminded me that Mozilla is also not a one-man show its TEAMWORK!

We need YOU!

Open-Source lives from Contribution to the Project by the Community. So its never too late or bad timing to join the Project. There is always a place for you to join the Mozilla and also its a super great place to do you very own impact to make the web a better place to everyone. You don’t need to be a super code expert, there are a lot of Areas at Mozilla where you can contribute.

So yeah get started today!

What i do currently:

Like i said i started in QA and now working as Sheriff at Mozilla. Its part of the Auto Tools Team at Mozilla.

The primary responsibility of the Sheriffs is and will always be to aid developers to easily, quickly, and seamlessly land their code in the proper location(s) and ensure that code does not break our automated tests. In the service of this objective, the Sheriffs work closely with the larger engineering organization to create and enforce landing policies that increase productivity while maintaining an efficient and robust automated testing system. Beyond the policy role, they have also become shepherds of automation quality by monitoring intermittent failures, performing uplifts and merges, and identifying poorly performing automation machines.

And we are also looking for new Community Members!

Why not Community Sheriff πŸ™‚

A Community Sheriff is working the other Sheriffs to keep the Code-Trees in a good shape and also working with Developers and also filing bugs for failing tests etc.

We are working currently on creating documentation to get new Community Members. So when you are interested in becoming a Community Sheriff let us know in the #ateam Channel on IRC (irc.mozilla.org).

Cheers,
