[Bug 2074330] Re: please enable framepointer for libio-dirent-perl

[Vladimir Petko]

** Also affects: libio-dirent-perl (Ubuntu Noble)
   Importance: Undecided
       Status: New

** Also affects: libio-dirent-perl (Ubuntu Oracular)
   Importance: Undecided
       Status: Fix Released

** Description changed:

- Note: libio-dirent-perl has very old packaging that has not been updated
- for a while.
+ [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
+ 
+ <package specific test plan goes here>
+ 
+ [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.
+ 
+ 
+ [Original Description]
+ Note: libio-dirent-perl has very old packaging that has not been updated for a while.
  
  The package can be switched to a modern debhelper version and this will
  allow to make it honour dpkg build flags.
