Overall Summary

Summary: This specification describes the steps required for storing raw debian/changelog files for all versions uploaded to Launchpad and the reasons why we are going to do it.

Goal/Deliverables: Allow users to fetch the debian/changelog file for every source version stored in Launchpad.

We will know we have finished when is not needed anymore.

Release Note



The primary reason for storing full changelog files for every source ever uploaded to Launchpad is to replace, but having this information available will also benefit uploaders and users which will have direct access to this contents (which isn't necessarily available in their system) without the need of unpacking sources.

Use cases


All debian/changelogs ever uploaded to ubuntu takes about 2.6GB (space used in c.u.c), we reckon PPAs would double it. We are talking about 5 ~ 6 GB in librarian, which doesn't seem to be a problem.

User Interface

We will be able to present the pristine changelog (probably linkified) additionally to the version we construct based on the version uploaded to ubuntu.


In upload-time, the debian/changelog file is easily reachable, it has to be uploaded to librarian and stored as a foreign key in SourcePackageRelease table. Since the file is mandatory for creating a source package upload it's very unlikely that we will need to deal with any corner-case.

Once stored the file will be published via the IArchive/+files ...
