Updating the Public Suffix List

PageSpeed ships with a copy of the Public Suffix List (PSL) via its dependency on domain registry provider (DRP). DRP was written at Google, and isn't used for anything else, so we've taken it on. When we build PageSpeed binaries we compile-in a cached copy of the PSL from the pinned version of DRP. So to update the PSL that we use we need to:

1. update DRP to the latest PSL
2. update PageSpeed's dependency to the latest DRP

Updating DRP

git clone git@github.com:pagespeed/domain-registry-provider.git
cd domain-registry-provider/src/
git checkout -b $USER-update-public-suffix-list
curl https://publicsuffix.org/list/effective_tld_names.dat > \
  third_party/effective_tld_names/effective_tld_names.dat
scripts/synthesize_entries.py \
  third_party/effective_tld_names/effective_tld_names.dat

Scan through the diff to make sure it looks reasonable.

Then edit domain-registry-provider/src/third_party/effective_tld_names/README.drp to update the downloaded date to today.

Then commit, push to github, and get your change reviewed. For example, here's the PR from the last time I did this: domain-registry-provider#6
