Published by Matthew Revell August 21, 2008 in Releases

We in the Launchpad team are proud to announce the 21st August 2008 release of Launchpad 2.1.8!

This release brings two items of good news for anyone who commits code to branches registered in Launchpad:

To subscribe to your own branch commits feed, visit your code overview page and click the feed icon in your browser’s address bar.

There’s more about karma for commits in our blog post.

Bugzilla and Trac plugin beta now open

Sharing the same bug report and comment history between communities is one of Launchpad’s most useful features.

With the beta of our new plugins for Bugzilla and Trac now open, projects who run their own external bug trackers can now also share bug comment histories with Launchpad.

Graham Binns from the Launchpad Bugs team blogs about how to take part in the beta, if you run a Bugzilla or Trac instance.

Regular updates on the Launchpad API beta

If you’re following the beta of the Launchpad API, you can now get regular updates on what’s new from Leonard Richardson, one of the Launchpad team working on the API.

Leonard’s posts are in the Launchad News blog’s API category.

Full details of Launchpad 2.1.8

Full details of the features and bug fixes that went into this release are on the Launchpad 2.1.8 milestone page.

If you come across any bugs in Launchpad, please report them.

We’ll be releasing Launchpad 2.1.9 on the 17th September.

In the mean time, join us each Thursday at 18.00 UTC in #launchpad-meeting on Freenode for the Launchpad team meeting and also any time on the launchpad-users mailing list.

Bugzilla and Trac plugins now in beta

Published by Graham Binns August 20, 2008 in Bug Tracking, Cool new stuff

A few weeks ago, Matt announced the new Launchpad plugins for Bugzilla and Trac.

The plugins allow bidirectional communication between Launchpad and the remote bug trackers that have them installed. Obviously, we need to test the plugins – and that’s where we need your help.

If you know of any Trac or Bugzilla instances whose administrators might be interested in installing the requisite Launchpad plugin – or indeed if you run such a bug tracker yourself – you can find details on how to install the plugins and what you need to do to get Launchpad to work with your bugtracker on the Launchpad Help wiki:

So, what will installing the plugins do? Well, initially, installing one of the plugins will mean that:

Once we’re happy that the plugins are working correctly we can use them to add some even cooler functionality to Launchpad:

The Bugzilla plugin is licensed under the Mozilla Public License and the Trac plugin is licensed under GPLv2.

If you’ve got any questions, don’t hesitate to contact us by email at feedback@launchpad.net.

Karma for commits!

Published by Matthew Revell in Code, Cool new stuff

While in some parts they take their pay in Warcraft gold, round here we’re karma fiends!

To feed the habit, Tim in Launchpad’s Code Hosting team has provided another way of earning karma: making commits to any Bazaar branch that’s registered to a project in Launchpad.

We’re backdating the karma for commits but, as with all karma the older the action is the less it’ll count towards your karma score; really old actions don’t count at all. Also, +junk branches don’t count towards karma at all.

This week in Launchpad’s web API

Published by Leonard Richardson August 15, 2008 in API, Cool new stuff, General

Now that the Launchpad web service API has entered beta, I’ll be posting an update every week about the improvements we make to it. This way you’ll always know what’s going on, and you’ll see when something you want to do becomes possible.

Web service improvements

This week I made one major change to the web service itself. There’s now a special top-level resource that’s an alias to “you” on Launchpad. This is a nice convenience when you’re writing scripts for yourself, but it’s practically essential if other people are going to be running your program.

Here’s how to get a reference to the person who’s running the script, using launchpadlib, our Python interface to the web service.

>>> me = launchpad.me
>>> print me.name
leonardr

If you’re not using launchpadlib, GET the service root at https://api.staging.launchpad.net/beta/, and you’ll see the URL to this resource as ‘me_link’. When you GET that URL you’ll be redirected to your own user account.

launchpadlib improvements

I spent most of my time working on launchpadlib. Apart from some bugfixes and performance improvements that you won’t even notice, I made three big improvements.

Introspection

Previously, to see what capabilities a launchpadlib object had, you had to check the reference documentation. (That documentation is two weeks out of date, by the way; we’ll be fixing that next week.) Now you can just call dir() on an object, and all of its Launchpad-derived attributes and methods will show up in the list. If you only want to see the Launchpad attributes or methods and not all the internal launchpadlib stuff, you can check lp_attributes or lp_operations. This code shows what you can do with a launchpadlib person object:

>>> me.lp_attributes
['self_link', 'resource_type_link', 'longitude', ... 'homepage_content']

>>> me.lp_operations
['addMember', ... 'setLocation']

Slices

The second new feature is the ability to slice Launchpad collections as though they were Python lists. Here’s some code that gets the 10 most recently filed bugs in Launchpad.

>>> recent_bugs = launchpad.bugs[:10]
>>> [bug.id for bug in recent_bugs]
[258042, 258041, 258040, 258039, 258038, 258037, 258036, 258033, 258032, 258030]

Previously, the only way to do this was to iterate over launchpad.bugs and insert a break statement when you’d had enough, which was very awkward.

Loading from bookmarks

The third new feature is the ability to bookmark launchpadlib objects and go back to them later, the way you can bookmark web pages in your browser. Here’s launchpadlib code to acquire a bug.

>>> a_bug = launchpad.bugs[251497]
>>> print a_bug.title
Make it possible to instantiate a resource from a URL

I can play around with that bug all I want within a Python session, but if I exit the Python session the bug will disappear. If I want to get the bug back later, I’ll need to find it again from scratch. Unless I store the bug’s unique ID (also known as its URL).

>>> print str(a_bug)
https://api.staging.launchpad.net/beta/bugs/251497

At this point I can write that string to a file or database. Later on, a different process might come online and load the string back into memory. That process can get the bug object back by passing the bug’s URL into launchpad.load().

>>> a_bug = launchpad.load("https://api.staging.launchpad.net/beta/bugs/251497")
>>> print a_bug.title
Make it possible to instantiate a resource from a URL

Pretty simple stuff–people have been saving URLs and passing them around to each other for over fifteen years. The advantage of our web service’s design is that it gives you the same power in a scripted environment.

Upcoming work

Next week I plan to spend most of my time on behind-the-scenes performance improvements. You won’t notice anything if you use launchpadlib. If you’re writing your own client, you’ll know what I’m talking about when I say “ETag support.”

Meanwhile, Edwin Grubbs will be working to expose Launchpad’s project registry through the web service.

See you next week!

Legal Page Updates

Published by Joey Stanford August 12, 2008 in General, Notifications

Hi,

Today I’m happy to announce two changes which appear on the Launchpad Legal page.

  1. The Launchpad Logo, previously unlicensed, is now licensed as “Creative Commons Attribution-No Derivative Works 2.0 UK: England & Wales”. “No Derivative” was chosen to preserve our branding integrity.
  2. The Launchpad Help wiki documentation and the Launchpad News blog, previously unlicensed, are now licensed as “Creative Commons Attribution 2.0 UK: England & Wales”.

These changes have been made in response to our users and other commercial entities inquiring if they can display/reuse/remix these items. Previously, any non-Launchpad use required explicit permission (except as permitted by fair-use).

Inside the new Launchpad web service API

Published by Leonard Richardson August 9, 2008 in API, Cool new stuff

If you’ve been wanting to integrate Launchpad into your development tools, or create scripts that read and write Launchpad’s dataset, your wait is over. We’ve released the initial version of our RESTful web service API to the beta testing team. Now you can integrate with Launchpad using our Python library or by making simple HTTP requests.

No longer will you need to screen-scrape or write scripts that pretend to be a web browser; your programs will be able to communicate directly with Launchpad. Our support for OAuth means your users can delegate a subset of their Launchpad privileges to your program or website, without handing over their Launchpad pasword.

Right now, the web service provides basic access to Launchpad’s people and bugs. We’re working now to expose more of Launchpad’s data–projects, milestones, and so on–and to improve the usability of the Python client. Once we’ve stabilized the framework, we’ll open up the web service API to everyone. In the meantime, you can try it out by joining the Launchpad Beta Testers team. Once you’re on the team, you can get started by visiting the help homepage.

Our Python library, launchpadlib, works as a “web service browser”. You can use it to navigate the web service from a Python script, the way you surf the Launchpad website from your web browser. You don’t need any special knowledge of web services to use launchpadlib; you can write natural-looking code like this:


>>> me = launchpad.people['my-username']
>>> me.display_name = 'My new display name'
>>> me.lp_save()

We’ll be improving launchpadlib and the web service simultaneously; this is just the beginning.

Survey about Launchpad’s upstream bug workflow

Published by Matthew Revell in General

As we’ve spoken about before on this blog, one of the cool things about Launchpad’s bug tracker is that it can link bugs together, regardless of whether they’re tracked in Launchpad or an external bug tracker.

This is great for Ubuntu, where people report issues against an Ubuntu package of an upstream project. Jorge Castro works on Ubuntu’s community team and wants to know how we could improve this for upstream projects.

So, if you’re from an upstream project and have an opinion on how we can improve the workflow between Launchpad and your external bug tracker, take Jorge’s survey.
