[Bug 2083937] Re: [SRU] Enable frame-pointer on Noble in update-notifier

[Timo Aaltonen]

Hello Julian, or anyone else affected,

Accepted update-notifier into noble-proposed. The package will build now
and be available at https://launchpad.net/ubuntu/+source/update-
notifier/3.192.68.1 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 on 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 add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
noble to verification-done-noble. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-noble. In either case, without details of your testing we will
not be able to proceed.

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

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

** Changed in: update-notifier (Ubuntu Noble)
       Status: In Progress => Fix Committed

** Tags added: verification-needed verification-needed-noble

Title:
  [SRU] Enable frame-pointer on Noble in update-notifier

Status in update-notifier package in Ubuntu:
  Invalid
Status in update-notifier source package in Noble:
  Fix Committed

Bug description:
  [ Impact ]
  In order to help developers with profiling, Ubuntu enabled frame-pointers for packages in the main archive.

  https://ubuntu.com/blog/ubuntu-performance-engineering-with-frame-
  pointers-by-default

  The `Affects` packages were missed due to the packaging issues. These
  have been fixed on Oracular and can now be ported to Noble.

  [ Test Plan ]

  Look at the DW_AT_producer in the associated debug ELF file for flags.
  -fno-omit-frame-pointer should be present after the fix.

  The following scripts can be used as a reference
  https://gist.github.com/julian-klode/85e55553f85c410a1b856a93dce77208
  https://gist.github.com/julian-klode/95818246eaef0ac6a54588f7f368e25c

  The autopkgtests cover the Python parts, so we should start update-
  notifier on a real system and see that it still starts. We don't
  expect any regressions from compiler flag changes, so I don't want to
  do a whole bunch of UI tests or anything.

  [ Where problems could occur ]

  No source changes are made. The packaging fixes have enabled other
  security hardening flags. This could have unintended effects.

  [ Other Info ]

  changes in dpkg have been made to make sure frame-pointers are not
  enabled on s390x and ppc64el.
