Launchpad’s web interface will be read-only, with other aspects offline, for around 90 minutes from 22.00 UTC on the 8th June 2011. This is to allow for our monthly database update.
Starts: 22.00 UTC 2011-06-08
Expected back by: 23.30 UTC 2011-06-08
Guessing relevant test modules with Fault Line
Published by Aaron Bentley in General
Launchpad’s test suite takes a long time to run. Far too long to wait for when you’ve made a change. And the likelihood that you’ve broken any given test is pretty small. So you probably want to start by running the tests that were likely to break.
You can usually guess which tests to run; if you’ve changed “archive.py“, you should probably run “test_archive“. But some connections are easier to miss, so I’ve hacked up a Fault Line, a bzr plugin that uses past changes to guess which test files correlate to the files you’ve changed. You can run it like so:
bin/test -m $(bzr fault-line --module-regex)
This will look at all the files you’ve changed, look at their recent history, and see which files tended to change in the last 100 revisions where you changed the specified files. The --module-regex option causes it to output a regular expression, assuming that the test files are Python modules. Otherwise, it would just output a list of the test files it found.
Thanks to Jelmer Vernoij, this is even easier to achieve for testing bzr. You just need to run “bzr selftest --auto“.
To install Fault Line, just run:
bzr branch lp:fault-line ~/.bazaar/plugins/faultline
It currently requires bzr 2.3 or later (e.g. stock Natty bzr).
Fault line is pretty limited right now. For example, the way it guesses what’s a test file is hard-coded. But a few days ago, it wasn’t even a proof of concept. Who knows what the future holds?
team owner no longer implies team member
Published by Robert Collins May 31, 2011 in Coming changes
A short headsup about an upcoming change.
A very long time ago the team owner was always a team member. This was changed to make team owners optionally members (sometime before 2008!). However the change was incomplete – there has been an inconsistency in the codebase ever since. For the details see bug 227494.
I wanted to let everyone know about us actually finishing this change though, because for a small number of teams (about 400) their administrators may be surprised when they cannot do things.
The inconsistency was this: if a team owner leaves the team, so they just own it, then they are not listed as a team member. But if they try to exercise a privilege the team grants – e.g. if the team is a bug supervisor – the team owners were able to do this. This setup made it impossible for users to accurately determine who can carry out the responsibilities of a team : the Launchpad web UI incorrectly reported team members.
The fix which will be deployed in the next day or so corrects this inconsistency: Team ownership will no longer grant access to anything that team membership grants.
For clarity, these are the rules around team owners:
- When a team owner is assigned (or a team made) the owner defaults to being an administrator-member.
- If a team owner deactivates their team membership then they are not considered a team member anymore: resources and access that team membership grants will not be available to the owner at this point.
- Team owners can always perform adminstrative tasks on the team: creating new administrators, edit the team description, rename the team etc.
- Point 3 allows an owner to add themself to the team they own even if they deactivated their membership previously.
Countdown to the pie
Published by Francis J. Lacoste May 27, 2011 in General
We are now one month away from the Dublin Thunderdome and the stakes of the game have increased substantially since last time! At UDS, Jonathan announced he was willing to take a pie in the face if we achieved our 0 critical bugs goal. Two others joined him in the bet.
As of this writing, we have 210 critical bugs left to fix to pie Jono, Ted and Neil. (203 actually, since 7 of those are bugs escalated after the bet announcement.) Unfortunately, their face seems pretty safe :-/ If we look at the trend of the last 4 weeks, we see that we are burning down about 12 bugs per week. At this rate, we would achieve this goal in 18 weeks, so around the end of September. 3 months too late for a pie! This week, the Yellow squad is starting on maintenance, so we’ll see if they can improve on the 12 bugs a week burn-down. I mean, that number is 3 times the long-term rate which is more like 4 a week, so we are definitively improving! Both because we are better at fixing bugs, but also because the number of newly found issues is declining. You can see the combined effect of this on the burndown graph as the slope gets much sharper on the right.
It doesn’t look much better on our third objective which is to have a free slot in the stakeholders Next queue. This week the Teal squad resumed work on the our project to improve Launchpad privacy features. They did an initial break-down of the project and they have work until the next UDS! The Red squad is finishing off derived distributions, probably before the Thunderdome. But even then, at that point we would be starting on adding customizable columns on search results. And the Next queue would still be full at 2 items. On the plus side, we won’t be over our work-in-process limit anymore 🙂
I’m looking forward to see how this all turns out in Dublin, but whatever happens, at the very least, we’ll have succeeded early on our 9s timeout objective.

Tilde or not tilde
Published by Matthew Revell in General
When Launchpad shows someone’s display name, it’s not always clear who it’s referring to.
With so many people registered in Launchpad, it’s not surprising that some of them share a name. However, every Launchpad id is unique. Mine’s matthew.revell and no matter how many other Matthew Revells there might be in Launchpad, I’ll always be the only one with that ID.
To help clarify who’s who, we’re going to show the ID in more places alongside the display name. Two of those places are the person picker — so you know for sure that you’re selecting the right person — and at the top of the profile page.
There was some discussion, though, as to whether people would recognise that we were showing the person’s Launchpad ID. One way to make it clearer, it was suggested, would be to place a tilde in front of the ID.
On Wednesday I set up a survey asking which of these you prefer:
And which of these you prefer:
Rather than say it straight out — i.e. do you like the tilde? — I wanted to see if people noticed it.
The majority of people who responded to the survey said they preferred the versions without the tilde.
For the person picker, 23.6% of the respondents preferred the version with the tilde and 76.4% preferred the version without.
For the profile page it was a little different and even more in favour of the version without the tilde: 18.4% preferred the version with the tilde, whereas 81.6% preferred the version without.
Thanks to everyone who took part. It’s now over the to Teal Squad to digest the results.

Help us test something new!
Published by Matthew Revell May 25, 2011 in General
My colleagues in the Teal Squad have been working on a small change that’ll make it easier to distinguish Launchpad users who have similar names.
We’ve got two quick questions in our new survey. Help us make it easier to tell who’s who in Launchpad.
The survey is open for 24 hours only, so get in before 18.00 UTC on the 26th May.
Take our short survey to help us make it easier to tell who’s who in Launchpad!

Congrats, nigelb and chrisjohnston!
Published by Martin Pool May 23, 2011 in General
Congratulations and virtual cupcakes to nigelb and chrisjohnston who got their first changes in to Launchpad, and to the reviewers who helped get them finished off and deployed.
jml said it so well at his recent short talk:

Coming soon: improved bug subscriptions
Published by Matthew Revell in Bug Tracking
Did you know we’re running a beta of Launchpad’s new bug subscriptions system?
If so, you may have heard that we were planning to take the new subscriptions system out of beta today.
There are, though, a couple of bugs that we want to fix before taking the new bug subscriptions system live. And one of those bugs requires an update to our database, which means a short amount of read-only time for Launchpad.
So, we’re now planning to make the new bugs subscription system live on June the 8th, which is our next scheduled database roll-out.
If you want to start using the new system straight away, join our beta team!

Love from Budapest
Published by Francis J. Lacoste May 20, 2011 in General
Jonathan (our Product Strategist) and I attended UDS-O in Budapest last week. Brad, Ian, Huw and Julian also came along for some part of it. And what great feedback we received from Ubuntu contributors! Working on a big and relatively old project like Launchpad can sometime be hard. From within, we are well aware that development is slower than it could be, that we have a lot of tech-debt and a big pile of Critical bugs, not to mention the hundreds of things that we know we could do to make Launchpad more compelling. Working distributed where you interact with users and fellow developers mostly through IRC and email, and sometime voice for “richer” communication makes it even easier to lose the perspective you get when you speak to real users face-to-face.
For me, UDS brought a nice uplifting fresh air (and that’s not a small feat when you know that this is a conference where you have sometime ~400 people in close proximity in the same room 😉 I don’t have enough fingers to count the number of people who thanked us for our performance work or for some other bug fixes we did! From their perspective, Launchpad development is going well and they want more! The performance improvements we did have been noticed! And people were thrilled by the new bug subscription work.
You can get a feel for the atmosphere by watching Jono’s 5-minutes lightning talk. The audience reaction is very much in line with the individual feedback we received.
It’s always great to know your effort are appreciated by your users. Thank to all the folks at UDS. Keep the love coming!

Nikki and the Robots
Published by Matthew Revell May 19, 2011 in Projects
Nikki and the Robots is the first game from Berlin based games studio Joyride Labs. It’s a retro-styled platformer with beautiful colours and an open source licence, with bugs tracked in Launchpad.
I asked Iwan & Sönke from Joyride Labs about the game.
Matthew: Nikki and the Robots is LGPL and Creative Commons licensed. What made you choose open source licences?
Iwan & Sönke: This one is easy! Our love of open source software and free art made us do it! Also we expect that being open will get us additional attention and love.
Our work and how we license it is an experiment too, so actually we ‘hope’ rather than expect. 🙂
Matthew: How are you planning to distribute the game once it’s ready?
Iwan & Sönke: We are working on the first part of Nikki and the Robots and will start in-dev-sales (pre-sale) once it is ready.
Game, editor and user levels will be free as in freedom. A part-proprietary organic story mode with enhanced levels and additional in-game-art will be available for pay.
Matthew: Can you tell me a bit more about the technology behind the game and the decisions you made? I see, for example, you’re using Haskell.
Iwan & Sönke: Haskell is just my (Sönke’s) favourite language. I have the impression that I can do coding in Haskell much faster than in other languages and I produce less bugs. Besides Haskell we use Qt and OpenGL as the graphics backend and Chipmunk as the physics engine. By the way: we completely rely on free software for compilation on all platforms (so, no VisualStudio or XCode, just gcc, cmake, mingw32, etc.).
Matthew: How are you finding Launchpad as a bug tracker?
Iwan & Sönke: It’s quite usable. Forum and wiki might be useful features to consider for the platform. (We use a free wiki system and will probably set up an own forum soon).
Matthew: Thanks to Iwan and Sönke. You can download an alpha of Nikki and the Robots from the Joyride Labs website.
