| Launchpad's branches are hosted in [[http://bazaar-vcs.org/|Bazaar]], using the most up-to-date repository format available. That means you'll need to use at least [[http://bazaar-vcs.org/Download|Bazaar 1.16.1]] to get Launchpad -- and please consider using [[https://lists.ubuntu.com/archives/bazaar/2009q3/060691.html|1.17]], which has just been released. | Launchpad's branches are hosted in Git.

| The '''`rocketfuel-setup`''' script first determines what release of Ubuntu you're running, then installs various lines into files under '''`/etc`''', to enable you to run Launchpad services locally. For example, it adds entries for "launchpad.dev", "bazaar.launchpad.dev", "lists.launchpad.dev", and others to your '''`/etc/hosts`''' file, so that after you build launchpad you can browse to '''`launchpad.dev`''' and see a locally-running instance. It also installs some packages, dependencies that Launchpad needs in order to run. This is why the sudo access is necessary; consult the script for details of what it's doing. | |
| Line 62: | Line 27: |
| Once it's got the system preparation out of the way, the script initializes a Bazaar repository (that's the '''`lp-branches`''' directory above), and pulls down a development trunk ('''`lp-branches/devel`'''). That will take a while. | == Where to get help == |
| Line 64: | Line 29: |
| After it gets that, it fetches the other dependencies, the third-party libraries, by invoking a separate script, '''`lp-branches/devel/utilities/rocketfuel-get`'''. That will take a while too, as there are almost thirty such libraries. Once it has all the dependencies, it links them into the trunk working tree, using the script '''`lp-branches/devel/utilities/link-external-sourcecode`'''. == Where to Get Help == Please ask questions sooner rather than later. The IRC channel '''`#launchpad-dev`''' at irc.freenode.net is where the experienced Launchpad developers will be hanging out; they can probably save you a lot of time.

Finally, please point out problems in this wiki whenever you find wrong information (we'll probably open up editing to most or all Launchpad-authenticated users soon, but for the first few days after open sourcing Launchpad, we're keeping the wiki more tightly controlled to avoid spam). |

Getting the Launchpad source code is fairly simple, but it's not the usual process of "download a package, unpack, build, and install". Since we do new rollouts of Launchpad directly from Git repositories anyway, that's how we distribute the source code to developers. There are no plans to package Launchpad; its deployment is quite complex.

The images/icons are still copyrighted traditionally, to protect Launchpad's visual identity. But they're shipped with the code and are fine to use for development and testing purposes.

Overview
Launchpad is a core of service-specific code surrounding various third-party libraries, some of which are installed. So the process of fetching Launchpad to build it looks something like this: grab the core code, grab all the libraries, unpack them into the right places in the tree, and then build the whole thing.
Fortunately, we've written scripts to take care of most of that, and instructions on using those scripts are below.
Launchpad's branches are hosted in Git. The source tree is about 90MB, although the total size of the repository you'll download is about 210MB, as you're getting the full history with it.
Getting it
To build and run a Launchpad development instance, see Running (we strongly recommend Running/LXD). If you just want to grab the development source code branch:
git clone https://git.launchpad.net/launchpad
To learn about alternative "trunk" branches, see Trunk.
