Launchpad news, July 2015

Here’s a summary of what the Launchpad team got up to in July.


  • We fixed a regression in the wrapping layout of side-by-side diffs on (#1436483)
  • Various code pages now have meta tags to redirect “go get" to the appropriate Bazaar or Git URL, allowing the removal of special-casing from the “go" tool (#1465467)
  • Merge proposal diffs including mention of binary patches no longer crash the new-and-improved code review comment mail logic (#1471426), and we fixed some line-counting bugs in that logic as well (#1472045)
  • Links to the Git code browsing interface now use shorter URL forms

We’ve also made a fair amount of progress on adding support for triggering webhooks from Launchpad (#342729), which will initially be hooked up for pushes to Git repositories.  The basic code model, webservice API, and job retry logic are all in place now, but we need to sort out a few more things including web UI and locking down the proxy configuration before we make it available for general use.  We’ll post a dedicated article about this once the feature becomes available.

Mail notifications

We posted recently about improved filtering options (#1474071).  In the process of doing so, we cleaned up several older problems with the mails we send:

  • Notifications for a bug’s initial message no longer include a References header, which confuses some versions of some mail clients (#320034)
  • Package upload notifications no longer attempt to transliterate non-ASCII characters in package maintainer names into ASCII equivalents; they now use RFC2047 encoding instead (#362957)
  • Notifications about duplicate bugs now include an X-Launchpad-Bug-Duplicate header (#363995)
  • Package build failure notifications now include a “You are receiving this email because …” rationale (#410893)

Package build infrastructure

  • The sbuild upgrade last month introduced some regressions in our handling of package builds that need to wait for dependencies (e.g. #1468755), and it’s taken a few goes to get this right; this is somewhat improved now, and the next builder deployment will fix all the currently-known bugs in this area
  • In the same area, we’ve made some progress on adding minimal support for Debian’s new build profiles syntax, applying fixes to upload processing and dependency-wait analysis, although this should still be considered bleeding-edge and unlikely to work from end to end
  • We’ve been working on adding support for building snap packages (#1476405), but there’s still more to do here; we should be able to make this available to some alpha testers around mid-August


  • We’ve arranged to redirect translations for the overlay PPA used for current Ubuntu phone images to the ubuntu-rtm/15.04 series so that they can be translated effectively (#1463723); we’re still working on copying translations into place from before this fix
  • Projects and project groups no longer have separately-editable “display name” and “title” fields, which were very similar in purpose; they now just have display names (#1853, #4449)
  • Cancelled live file system builds are sorted to the end of the build history, rather than the start (#1424672)
