Hi, Greg and Sasha add the "X-stable: review" to their patch bombs, with the intention that people will be able to filter these out should they desire to do so. For example, I usually want all threads that match code I care about, but I don't regularly want to see thousand-patch stable series. So this header is helpful. However, I'm not able to formulate a query for lore (to pass to `lei q`) that will match on negating it. The idea would be to exclude the thread if the parent has this header. It looks like public inbox might only index on some headers, but can't generically search all? I'm not sure how it works, but queries only seem to half way work when searching for that header. In the meantime, I've been using this ugly bash script, which gets the job done, but means I have to download everything locally first: #!/bin/bash PWD="${BASH_SOURCE[0]}" PWD="${PWD%/*}" set -e cd "$PWD" echo "[+] Syncing new mail" >&2 lei up "$PWD" echo "[+] Cleaning up stable patch bombs" >&2 mapfile -d $'\0' -t parents < <(grep -F -x -Z -r -l 'X-stable: review' cur tmp new) { [[ -f stable-message-ids ]] && cat stable-message-ids [[ ${#parents[@]} -gt 0 ]] && sed -n 's/^Message-ID: <\(.*\)>$/\1/p' "${parents[@]}" } | sort -u > stable-message-ids.new mv stable-message-ids.new stable-message-ids [[ -s stable-message-ids ]] || exit 0 mapfile -d $'\0' -t children < <(grep -F -Z -r -l -f - cur tmp new < stable-message-ids) total=$(( ${#parents[@]} + ${#children[@]} )) [[ $total -gt 0 ]] || exit 0 echo "# rm <...$total messages...>" >&2 rm -f "${parents[@]}" "${children[@]}" This results in something like: zx2c4@thinkpad ~/Projects/lkml $ ./update.bash [+] Syncing new mail # https://lore.kernel.org/all/ limiting ... # /usr/bin/curl -gSf -s -d '' https://lore.kernel.org/all/?x=m&t=1&q=(... [+] Cleaning up stable patch bombs # rm <...24593 messages...> It works, but it'd be nice to not even download these messages in the first place. Since I'm deleting message I don't want, I have to keep track of the message IDs of those deleted messages with the stable header in case replies come in later. That's some book keeping, sheesh! Any thoughts on this workflow? Jason
