[Bug 1038961] Re: Maximum override line length is too short

[Adam Conrad]

Hello Colin, or anyone else affected,

Accepted apt into precise-proposed. The package will build now and be
available at
http://launchpad.net/ubuntu/+source/apt/0.8.16~exp12ubuntu10.3 in a few
hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please change the bug tag from
verification-needed to verification-done.  If it does not, change the
tag to verification-failed.  In either case, details of your testing
will help us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

** Changed in: apt (Ubuntu Precise)
       Status: In Progress => Fix Committed

** Tags added: verification-needed

** Changed in: apt (Ubuntu Lucid)

  Maximum override line length is too short

Bug description:
  [Impact] The Launchpad publisher is producing malformed Task lines in Packages files, which has the potential to cause image builds to be incomplete.
  [Test Case] Grab the extra-override input files from the primary archive and try to run apt-ftparchive using them (perhaps cut down to include just the longest lines).  It should avoid emitting "Malformed override" messages and should produce non-truncated Task lines in Packages files.
  [Regression Potential] Barring toolchain bugs, any regressions should be confined to apt-ftparchive.  (But this change is very simple, so I'm not especially worried.)

  We see quite a few messages like this from the publisher:

    W: Malformed override /srv/launchpad.net/ubuntu-archive/ubuntu-
  overrides/override.quantal.extra.main line 14628 #2

  These correspond to override lines that are too long.  This example
  is:

    libmng1/powerpc Task    ubuntu-desktop, ubuntu-usb, kubuntu-desktop,
  kubuntu-active-desktop, kubuntu-active, edubuntu-desktop, edubuntu-
  desktop-kde, edubuntu-usb, xubuntu-desktop, mythbuntu-frontend,
  mythbuntu-frontend, mythbuntu-desktop, mythbuntu-backend-slave,
  mythbuntu-backend-slave, mythbuntu-backend-master, mythbuntu-backend-
  master, ubuntustudio-generation, ubuntustudio-video, ubuntustudio-
  audio-plugins, ubuntustudio-publishing, ubuntustudio-photography,
  ubuntustudio-graphics, ubuntustudio-recording

  This carries over into truncated Task fields in Packages files.

  Override::ReadOverride currently has "char Line[500]", which is the
  cause of this.  Ideally, this code would handle arbitrary-length
  lines.  However, in practice, the maximum line length we're seeing in
  quantal is 594, so simply doubling this to 1000 would do nicely for
  now.
