.github: set link for GH issue feature template

[aanm]

To check for backport PRs we should check the label backport/1.X.

Does the "backports" keyword search not work?

Originally I avoided setting it like is proposed here because label:backport/1.X is guaranteed to link to an empty result, and we typically do releases for multiple branches at the same time so it doesn't matter if the filter catches more than the specific branch.

That said, if this works better for you then I'm OK with merging it.

No, look at the difference between the 2 search results:

What I usually do is search and replace it automatically with a bash function that is something like:

gen_release_template(){
  # change to Cilium directory first
  local major="${1}"
  local minor="${2}"
  local patch="${3}"
  local next_patch="$(( ${patch} + 1 ))"
  sed "s/1.X/${major}.${minor}/g;s/X.Y.Z/${major}.${minor}.${patch}/g;s/X.Y.W/${major}.${minor}.${next_patch}/g;s/X.Y/${major}.${minor}/g" .github/ISSUE_TEMPLATE/release_template.md | xclip -selection c
}

then for example gen_release_template 1 9 10 and replace the GH issue with whatever is on my clipboard. This guarantees the links will work.

Can we put that somewhere in contrib/ too? I usually only put half-effort into updating the numbers since it's inconvenient.

Actually minor hack on top, I just integrated this into my local scripts:

GH_RELEASE_TEMPLATE="/path/to/cilium-master/.github/ISSUE_TEMPLATE/release_template.md"
gen_release_template(){                                                         
  if [ ! -e VERSION ]; then                                                     
    >&2 echo "No VERSION found. Are you in the Cilium directory?"               
    exit 1                                                                      
  fi                                                                            
                                                                                
  local version="$(cat VERSION)"                                                
  local major="$(echo $version | sed 's/^\([0-9]\+\).*/\1/g')"                  
  local minor="$(echo $version | sed 's/^[0-9]\+\.\([0-9]\+\).*/\1/g')"         
  local patch="$(echo $version | sed 's/^[0-9]\+\.[0-9]\+\.\([0-9]\+\).*/\1/g')"
                                                                                
  local next_patch="$(( ${patch} + 1 ))"                                        
  sed "s/1.X/${major}.${minor}/g;s/X.Y.Z/${major}.${minor}.${patch}/g;s/X.Y.W/${major}.${minor}.${next_patch}/g;s/X.Y/${major}.${minor}/g" "$GH_RELEASE_TEMPLATE" | xclip -selection c
  echo "Copied release template for ${major}.${minor}.${next_patch} to the clipboard."
}

This way I can just go into the worktree for an older release and run it without worrying about which version, and it will pick the right one.
