The inclusions were removed with the following very crude script and the resulting breakage was fixed up by hand. The manual fixups did either revert the changes done by the script, replace a generic header with a more specific one or replace a header with a forward declaration. find . -name "*.idl" | grep -v web-platform | grep -v third_party | while read path; do interfaces=$(grep "^\(class\|interface\).*:.*" "$path" | cut -d' ' -f2) if [ -n "$interfaces" ]; then if [[ "$interfaces" == *$'\n'* ]]; then regexp="\(" for i in $interfaces; do regexp="$regexp$i\|"; done regexp="${regexp%%\\\|}\)" else regexp="$interfaces" fi interface=$(basename "$path") rg -l "#include.*${interface%%.idl}.h" . | while read path2; do hits=$(grep -v "#include.*${interface%%.idl}.h" "$path2" | grep -c "$regexp" ) if [ $hits -eq 0 ]; then echo "Removing ${interface} from ${path2}" grep -v "#include.*${interface%%.idl}.h" "$path2" > "$path2".tmp mv -f "$path2".tmp "$path2" fi done fi done Differential Revision: https://phabricator.services.mozilla.com/D55443 --HG-- extra : moz-landing-system : lando
